As shown in FIGS. 1 and 2, the apparatus for inflating and blowing, provided by the embodiment of the present invention, includes an air pump 10, an air-blowing device 20, a motor 30, and a housing 40, such as an outer shell 40.

The motor 30 is connected to the air-blowing device 20 and is connected to the air pump 10, so as to drive the air-blowing device 20 and/or the air pump 10 to operate.

The air pump 10, the air-blowing device 20, and the motor 30 may be all located inside the outer shell 40.

In a preferred embodiment, the air-blowing device 20, the motor 30, and the air pump 10 are arranged in sequence along the first direction of the outer shell 40 (for example, the length or width direction of the outer shell; what the FIG. 2 shows is along the length direction).

The outer shell 40 is provided with an air inlet 40a. The air-blowing device 20 (for example, an impeller 20, as shown in FIG. 4) is located adjacent to the air inlet 40a. An airflow enters the air-blowing device 20 from the air inlet 40a on the outer shell, and then enters the blowing passage 40b. The blowing passage 40b is used to guide the blowing airflow flowing inside the housing 40. The blowing passage 40b is connected to the air-blowing device 20 and is also connected to the air outlet 50.

Preferably, a part of the blowing passage 40b is located between the air pump 10 and the housing 40. More preferably, the space between the air pump 10 and the housing 40 forms a part of the blowing passage 40b.

Further preferably, a part of the blowing passage 40b is located between the motor 30 and the housing 40. More preferably, the space between the motor 30 and the housing 40 forms a part of the blowing passage 40b.

The outer shell 40 is provided with a first interface 51 and a second interface 52. The first interface 51 is used for connecting to an external to-be-blown device, and the second interface 52 is used for connecting to an external to-be-inflated device. Therein, the first interface 51 includes a blowing hole 51a, and the second interface 52 includes an air outlet hole 52a. The first interface 51/blowing hole 51a is in communication with the air-blowing device 20, and is used for the air-blowing device 20 to output air; the second interface 52/air outlet hole 52a is in communication with the air pump 10, and is used for the air pump 10 to output air.

In a preferred embodiment, the second interface 52 is located inside the first interface 51. For example, an enclosed area where the first interface 51 and the outer shell 40 are connected completely covers an enclosed area where the second interface 52 and the outer shell 40 are connected. More preferably, the second interface 52 and the first interface 51 are coaxially arranged, for example, the second interface 52 and the first interface 51 form concentric rings/circles, wherein one of them is located at a relatively inner side and the other one is located at a relatively outer side.

In another embodiment, the first interface 51 and the second interface 52 may be two interfaces that do not overlap each other, that is to say, two independent interfaces.

It should be understood that when the air pump 10 inflates the to-be-inflated device through the second interface 52, it is able to inflate the to-be-inflated device with high-pressure air. Therefore, the to-be-inflated device is normally a device that needs to be inflated with high-pressure air, for example, automobile tires, etc. When the air-blowing device 20 blows air to the to-be-blown device through the first interface 51, it is able to quickly input a large amount of air to the to-be-blown device. Therefore, the to-be-blown device is normally a device that needs a large amount of air, for example, air mattresses, etc. The present invention is able to choose to use the air pump 10, or use the air-blowing device 20, or use the air pump 10 and the air-blowing device 20 at the same time, according to an use scenario.

It should be understood that the present invention preferably uses the same motor 30 to drive the air-blowing device 20 and to drive the air pump 10. For example, the present invention preferably provides only one motor 30 to drive the air pump 10 and the air-blowing device 20 to operate.

The motor is drivingly connected to the air-blowing device. The motor is drivingly connected to the air pump.

For example, as shown in FIG. 8, an output end (output shaft) 302 of the motor 30 is connected to the air-blowing device 20, for example, connected to the impeller of the air-blowing device 20, so as to drive the impeller to rotate; another output end (output shaft) 301 of the motor 30 is connected to the air pump 10, for example, connected to the piston assembly 11 of the air pump. For example, the output end 301 of the motor is provided with a gear assembly, and the piston assembly 11 of the air pump is provided with another gear assembly. Through the meshing of the gear assemblies, the motor drives the piston assembly 11, and drives a piston rod to move.

Preferably, the output shaft 302 of the motor 30 being connected to the air-blowing device 20 and the output shaft 301 of the motor 30 being connected to the air pump 10 are collinear (located on the same line), or even coaxial (belonging to the same output shaft). For example, the output shaft 302 and the output shaft 301 may come from the output of the same rotating shaft in the motor 30.

In the embodiment shown in FIG. 8, the motor 30 is drivingly connected to the air-blowing device 20 and to the air pump 10, through the output ends 302 and 301 located on the two sides (left and right sides), respectively.

In another embodiment, the motor 30 may be drivingly connected to the air-blowing device 20 and to the air pump 10 in sequence, through an output end on the same side (for example, through the output end 301 on the left side). For example, along the axial direction, the output end 301 of the motor 30 is first drivingly connected to the air-blowing device 20 (for example, the impeller of the air-blowing device 20 is fixedly connected to the output end 301 through a fastener), and then drivingly connected to the air pump 10 (for example, the air pump 10 is drivingly connected to the output end 301 through a gear assembly).

In the present invention, the motor 30 may drive the air pump 10 and the air-blowing device 20 to operate at the same time.

In a preferred embodiment, when the motor 30 is running, both the air pump 10 and the air-blowing device 20 are running at the same time. When the motor 30 stops, both the air pump 10 and the air-blowing device 20 stop.

In another embodiment, the motor 30 of the present invention is able to drive the air pump and the air-blowing device 20 to operate separately. That is, the motor 30 may be configured to, in an inflating mode, drive only the air pump 10 to operate, while the air-blowing device 20 does not operate; and/or, the motor 30 may be configured to, in an air-blowing mode, drive only the air-blowing device 20 to operate, while the air pump 10 does not operate.

It should be understood that the first interface 51 and the second interface 52 of the present invention may be combined together, and of course, the first interface 51 and the second interface 52 may be independent interfaces.

In one embodiment of the apparatus for inflating and blowing of this embodiment, the air pump 10 can inflate the to-be-inflated device through the second interface 52, and the air-blowing device 20 can blow air to the to-be-blown device through the first interface 51. Moreover, during inflating and/or blowing, both the air pump 10 and the air-blowing device 20 are driven by the same motor 30. Thus, compared with the prior art, the space occupied by another additional motor 30 can be saved, which can reduce the size of the outer shell 40, reduce the volume and weight of the apparatus for inflating and blowing, and facilitate the portability and use of the apparatus. For example, in a practical application scenario, the apparatus for inflating and blowing can be used as an emergency device for vehicles, so it will be placed in a vehicle for a long time. Reducing the volume and weight of the apparatus for inflating and blowing can make it more convenient to be carried in the vehicle and be used in emergencies.

As shown in FIGS. 1 and 2, in an embodiment of the present invention, the air-blowing device 20 and the air pump 10 are arranged in sequence along the first direction a. Therein, the first direction a is preferably the direction of the length of the outer shell 40, that is, the longitudinal direction of the outer shell 40. This arrangement allows the air-blowing device 20 and the air pump 10 to be more compactly disposed inside the outer shell 40, which is beneficial for the structural integration inside the outer shell 40, and further miniaturizies the apparatus for inflating and blowing, so as to facilitate the portability and use of the apparatus.

As shown in FIGS. 1 and 2, in an embodiment of the present invention, an air outlet 50 is provided at an end of the outer shell 40 in the first direction a. The air outlet 50 includes a first interface 51. A blowing passage 40b is provided between the air pump 10 and the inner wall of the outer shell 40. The air-blowing device 20 is in communication with the air outlet 50 (for example, in communication with the blowing hole 51a) through the blowing passage 40b. It can be understood that there is a distance between the first interface 51 and the air-blowing device 20, and the blowing passage 40b is able to guide the air outputted by the air-blowing device 20. It helps to achieve a directional airflow from the air-blowing device 20. Moreover, since the blowing passage 40b directly utilizes the space between the air-blowing device 20 and the inner wall of the outer shell 40, it will not occupy additional space in the apparatus for inflating and blowing. It should be understood that, in this embodiment, the blowing passage 40b may be a pipe provided between the air pump 10 and the inner wall of the outer shell 40, alternatively, it may be a passage directly formed by the space between a main body of the air pump 10 and the inner wall of the outer shell 40.

For example, the space between the main body of the air pump 10 and the inner wall of the outer shell 40 forms at least a part of the blowing passage 40b. Thereby, on the one hand, the structure of the apparatus for inflating and blowing can be simplified, and its weight can be reduced, so as to facilitate the portability; on the other hand, when the air-blowing device 20 outputs air along the blowing passage 40b, the airflow of the blowing passage 40b can also provide sufficient-and-stable ambient airflow for the air pump 10. When the air pump 10 is working, the airflow in the blowing passage 40b can serve as the ambient air of the air pump, and can directly enter the air pump 10. Therefore, this arrangement is also beneficial to the airflow and air output of the air pump 10.

As shown in FIGS. 1 and 2, in an embodiment of the present invention, one end of the outer shell 40 is provided with an air inlet 40a, for example, the front end along the first direction a is provided with an air inlet 40a. It should be understood that since the air-blowing device 20 and the air pump 10 are arranged in sequence along the first direction a, an air intake port of the air-blowing device 20 is close to the air inlet 40a. Thereby, it helps to introduce outside air into the apparatus for inflating and blowing, through the air-blowing device 20. Combined with the arrangement that the first interface 51 is arranged at the other end of the outer shell 40 along the first direction a, the air intaking and the air outputting of the air-blowing device 20 are arranged along the length direction of the outer shell 40, and the air can flow quickly along the first direction a, under the guidance of the air-blowing device 20. Thereby, it helps the air-blowing device 20 to output air and to provide a large amount of air to the to-be-blown device.

As shown in FIGS. 1 and 2, in an embodiment of the present invention, the other end of the outer shell 40 along the first direction a is provided with a second interface 52. The air flows in through the air inlet 40a, and enters the blowing passage 40b as ambient air, and enters the air intake port of the air pump 10. When the air pump 10 is running, the high-pressure air is outputted through the second interface 52, so as to provide high-pressure air to the to-be-inflated device. It should be noted that in the present invention, with the guidance of the air-blowing device 20, the outside air is accelerated to enter the blowing passage 40b, so that the air pump 10 can be provided with stable-and-sufficient ambient air, and the inflating efficiency is thus improved. Of course, even when the air-blowing device 20 is not running, the outside air can also pass through the air-blowing device 20, and enter the blowing passage 40b, and enter the air pump 10, so as to achieve the inflating by the air pump 10. In addition, since both the first interface 51 and the second interface 52 are arranged at the other end of the outer shell 40, it is convenient for a user to connect an to-be-blown device and/or an to-be-inflated device, and thus easy to use.

As shown in FIGS. 1 and 2, in an embodiment of the present invention, the motor 30 is located between the air pump 10 and the air-blowing device 20. The motor 30 may be close to the air-blowing device 20 and at the same time close to the air pump 10, which makes it more convenient for the motor 30 to be drivingly connected to the air pump 10 and to the air-blowing device 20. The structural connection can be simple, and there is no need to additionally lengthen the driving shaft, which makes the structure of the apparatus for inflating and blowing more compact and reasonable. Moreover, placing the motor 30 between the air pump 10 and the air-blowing device 20 also allows the air-blowing device 20 to be closer to the air inlet 40a, which facilitates the air-blowing device 20 to guide outside air into the apparatus for inflating and blowing. It can be understood that by this arrangement, the air pump 10, the motor 30, and the air-blowing device 20 are arranged in sequence along the first direction a, thereby, the overall shape may better fit the shape of the outer shell 40, further miniaturizing the apparatus for inflating and blowing, so as to facilitate the portability and use of the apparatus. Of course, in some other embodiments, the motor 30 may be located on a side of the air-blowing device 20 wherein the side of the air-blowing device 20 is away from the air pump 10. That is, the motor 30, the air-blowing device 20, and the air pump 10 are arranged in sequence along the first direction a.

As shown in FIGS. 1 and 2, in an embodiment of the present invention, one end of the motor 30 is provided with a first output shaft 301, and another end of the motor 30 is provided with a second output shaft 302. The first output shaft is configured to drive the air pump 10, and the second output shaft is configured to drive the air-blowing device 20. Thereby, the motor 30 can drive the air-blowing device 20 and the air pump 10 to operate, so to achieve air outputting and air blowing.

In some embodiments, a clutch is provided between the first output shaft of the motor 30 and the first driving shaft for the air pump 10, and/or a clutch is provided between the second output shaft of the motor 30 and the second driving shaft for the air-blowing device 20. Thereby, the user can, according to his needs, connect only the clutch between the first output shaft of the motor 30 and the first driving shaft for the air pump 10, so as to drive the air pump 10 to operate alone; or, connect only the clutch between the second output shaft of the motor 30 and the second driving shaft for the air-blowing device 20, so as to drive the air-blowing device 20 to operate alone; or, connect the clutches at both ends of the motor 30 at the same time, so that the motor 30 drives the air pump 10 and the air-blowing device 20 to operate at the same time.

In some embodiments, a clutch is provided between the first output shaft of the motor 30 and the first driving shaft for the air pump 10, while the second output shaft of the motor 30 and the second driving shaft for the air-blowing device 20 are directly drivingly connected. Thereby, the user may, according to his needs, connect the clutch between the first output shaft of the motor 30 and the first driving shaft for the air pump 10, so that the motor 30 drives the air pump 10 and the air-blowing device 20 to operate at the same time; or, not activate the clutch, so as to drive the air-blowing device 20 to operate alone.

In some embodiments, the first output shaft of the motor 30 and the first driving shaft for the air pump 10 are directly drivingly connected, while a clutch is provided between the second output shaft of the motor 30 and the second driving shaft for the air-blowing device 20. Thereby, the user may, according to his needs, connect the clutch between the second output shaft of the motor 30 and the second driving shaft for the air-blowing device 20, so that the motor 30 drives the air pump 10 and the air-blowing device 20 to operate at the same time; or, not activate the clutch, so as to drive the air pump 10 to operate alone.

For example, the clutch includes an electromagnetic friction clutch. Therein, the electromagnetic friction clutch includes an input end, an output end, an electromagnetic plate, a friction plate, and an armature. The electromagnetic plate and the friction plate are located at the input end, the input end is connected to the output shaft, the armature is located at the output end, and the output end is connected to the driving shaft. When the clutch is not powered, the input end and the output end are disconnected and a torque cannot be transmitted. When the clutch is powered, the armature is attached/connected to the friction plate through the electromagnetic plate, and a torque can be transmitted between the input end and the output end, so that the output shaft of the motor 30 is able to drive the corresponding driving shaft. Of course, the clutch may be of some other types, which will not be described here.

As shown in FIGS. 1 to 3, in an embodiment of the present invention, the apparatus for inflating and blowing further includes an air-passing component 60.

The air-passing component 60 is located in an air outlet direction of the air-blowing device. The air-passing component 60 helps to guide the airflow from the air-blowing device 20 into the blowing passage 40b. In order to make the structure more compact, it is preferred that the air-passing component 60 is so installed as to surround at least a part of the motor 30 (or of the air pump 10).

For example, the air-passing component 60 is provided with a mounting hole 60a. At least one selected from the air-blowing device 20, the motor 30, and the air pump 10 may be fixed in the mounting hole 60a. On the one hand, at least one selected from the air-blowing device 20, the motor 30, and the air pump 10 can be stably installed by the help of the air-passing component 60. On the other hand, the air-passing component 60 can be used as an air guiding structure inside the apparatus for inflating and blowing, to direct the airflow from the air-blowing device 20 into the blowing passage 40b, so as to facilitate the air output of the air-blowing device 20 and the air output of the air pump 10. It should be understood that the air-passing component 60 can be used to fix only one among the air-blowing device 20, the motor 30, and the air pump 10, or simultaneously fix two or more among the air-blowing device 20, the motor 30, and the air pump 10, as long as the air-passing component 60 can guarantee a smooth air output of the air-blowing device 20 as well as a smooth air output of the air pump 10.

As shown in FIGS. 2 and 3, for example, a periphery of the air-passing component 60 is adapted to the inner wall of the outer shell 40 and is connected to the inner wall of the outer shell 40 by snap-fit connection. Thereby, the air-passing component 60 can be stably installed, so as to achieve a stable support for the at least one selected from the air-blowing device 20, the motor 30, and the air pump 10. In another embodiment, the air-passing component 60 and the outer shell 40 may be integrated into one piece.

As shown in FIGS. 1 to 3, for example, the mounting hole 60a is located in the air-passing component 60, and in the middle of the outer shell 40 of a direction that is perpendicular to the first direction a. Thereby, at least one selected from the air-blowing device 20, the motor 30, and the air pump 10 can be stably installed in the middle of the outer shell 40, so that air-blowing device 20, the motor 30, and the air pump 10 as a whole are centrally located inside the outer shell 40, especially the impeller of the air-blowing device 20 is centrally located, so that the air-blowing device 20 can be compactly arranged as a whole in the housing. In this example, the air inlet 40a, the air outlet hole 52a, and the blowing hole 51a may be also located in the middle of the outer shell 40 of a direction that is perpendicular to the first direction a, so that the apparatus for inflating and blowing can have stable-and-balanced air outlet and air output.

As shown in FIGS. 2 and 3, for example, the mounting hole 60a of the air-passing component 60 may be used for fixing the motor 30. When the motor 30 is located between the air-blowing device 20 and the air pump 10, the motor 30 may be stably fastened in the mounting hole 60a, so as to stably drive the air pump 10 and/or the air-blowing device 20. In this example, a periphery at an end of the motor 30 is adapted to the mounting hole 60a, so as to achieve stable installation of the motor 30.

As shown in FIGS. 1 to 3, in an embodiment of the present invention, the apparatus for inflating and blowing includes an air-passing component 60. The air-passing component 60 is provided with a through hole 60b for blowing, and the air-blowing device 20 is provided with an air outlet port. The air outlet port is in communication with the blowing hole 51a through the through hole 60b for blowing. The air-passing component 60 is able to guide the air output of the air-blowing device 20, so as to help to output air to the to-be-blown device, thereby improving the blowing efficiency.

As shown in FIGS. 2 and 3, for example, the through holes 60b for blowing are arranged at an outer circumference of the air-passing component 60 in a surrounding manner, so that the through holes 60b for blowing can be arranged to face the air outlet port of the air-blowing device 20, so as to guide the air output of the air-blowing device 20. Specifically, the air-blowing device 20 is arranged around the mounting hole 60a. Thereby, the air-passing component 60 can, on the one hand, stabilize the internal structure of the apparatus for inflating and blowing, and on the other hand, guide the air output of the air-blowing device 20 and improve the blowing efficiency.

As shown in FIGS. 1 and 2, in an embodiment of the present invention, the air-blowing device 20, the motor 30, and the air pump 10 are arranged in sequence along the first direction a. The air-passing component 60 is located close to the air-blowing device 20, and the mounting hole 60a is used to fix an end of the motor 30 which is close to the air-blowing device 20, so that the second output shaft of the motor 30 can stably support and drive the air-blowing device 20 to operate. The through holes 60b for blowing are arranged around the mounting hole 60a. One end of the through hole 60b for blowing is in communication with the air outlet port of the air-blowing device 20, and the other end of the through hole 60b for blowing is in communication with the blowing passage 40b, which is formed among the motor 30, the air pump 10, and the inner wall of the outer shell 40. Thereby, the air outlet port of the air-blowing device 20 is in communication with the blowing hole 51a, through the through hole 60b for blowing and the blowing passage 40b in sequence. As shown in FIG. 2, when the air-blowing device 20 is running, the outputted air can pass through the through hole 60b for blowing, the blowing passage 40b, and the blowing hole 51a, to achieve the air output of the air-blowing device 20.

As shown in FIGS. 1 and 4, in an embodiment of the present invention, the air-blowing device 20 includes an impeller, and the motor 30 is connected to the impeller, so as to drive the impeller to rotate. Under the rotation of the impeller, the air in the air intake port of the air-blowing device 20 can be guided to the air outlet port, so as to achieve air output.

As shown in FIGS. 1 and 4, in an embodiment of the present invention, the drive axis (rotation axis) of the impeller is arranged along the first direction a. Thereby, the impeller is able to output air along the first direction a. Combined with the above embodiment, the air outputted by the air-blowing device 20 can be outputted through the blowing hole 51a along the first direction a, which is beneficial to efficient air output of the air-blowing device 20.

As shown in FIGS. 1 and 4, in an embodiment of the present invention, the impeller includes a rotating member 21 and multiple blades 22. The rotating member 21 is connected to the motor 30, and the multiple blades 22 are connected to the circumference of the rotating member 21 in a surrounding manner.

Preferably, the impeller further includes a baffle 23. Preferably, the baffle 23 is located on a plane perpendicular to the rotation axis (first direction a) of the impeller. The baffle 23 is located on a side which is close to the air inlet 40a. The baffle 23 is used to prevent airflow from flowing toward the air inlet, thereby prompting the airflow to flow toward the air outlet. In addition, since the blades 22 of the air-blowing device 20 often have a relatively large area, the baffle 23 can also play a role of fixing and strengthening, so as to prevent the blades 22 from breaking during rotation.

The rotating member 21 and the multiple blades 22 are connected to the baffle 23. An air intake port is provided on a circumferential side of the multiple blades 22, and an air outlet port is provided on a side of the multiple blades 22 facing away from the baffle 23. The motor 30 drives the rotating member 21 to rotate, so as to drive the multiple blades 22 to rotate around the rotating member 21. Through the rotation of the multiple blades 22, the air around the multiple blades 22 (the air at a circumferential side of the multiple blades 22) is guided to the air outlet port, and the airflow flows from a side of the impeller to the axial direction of the impeller, so as to achieve the air output of the air-blowing device 20.

In one embodiment, a plane or a curved surface where a blade 22 is located is perpendicular to the baffle 23. In other words, the plane or the curved surface where the blade 22 is located is parallel to the rotation axis (first direction a) of the impeller 22. In another embodiment, in order to strengthen the direction of the air output, the plane or the curved surface where the blade 22 is located may not be perpendicular to the baffle 23. In other words, the plane or the curved surface where the blade 22 is located is not parallel to the rotation axis (first direction a) of the impeller 22, but has a certain inclination angle.

In this embodiment, the baffle 23 is arranged toward the air inlet 40a, which can prevent external dust from directly entering the air-blowing device 20 and some other structures, so as to ensure that the apparatus for inflating and blowing can work stably. Of course, in some other embodiments, the baffle 23 may be omitted. Thereby, a side of the multiple blades 22 facing the air inlet 40a is the air intake port, and the airflow flows directly along the axial direction of the impeller, to achieve the air output of the air-blowing device 20. Especially when the plane or the curved surface where the blade 22 is located is not parallel to the rotation axis (first direction a) of the impeller 22, and has a certain inclination angle, the airflow can flow toward the direction of the air outlet even without a baffle.

As shown in FIG. 3b, the air-passing component 60 of the present invention has an inner wall 601, an outer wall 602, and multiple partitions 603 located between the inner wall 601 and the outer wall 602.

Therein, the outer wall 602 may have a shape of a ring (or a part of a ring); the inner wall 601 may have a shape of a ring (or a part of a ring).

The inner wall 601 forms the mounting hole 60a. It can be used for installing at least a part of the motor 30 or a part of the air pump 10 therein, thereby making the structure more compact.

A notch 60c may be formed on the outer wall 602 and the inner wall 601. For example, the notch 60c is used for placing electric wires of the motor 30.

Several partitions 603 are provided between the inner wall 601 and the outer wall 602. Preferably, a plane or a curved surface where a partition 603 is located is not parallel to the rotation axis (first direction a) of the impeller 22, but has a certain inclination angle (as shown in FIG. 3b), thereby an air-guiding duct 60b from the direction of air inlet to the direction of air outlet (from the air inlet 40 to the blowing passage 40b) is formed.

As shown in FIGS. 1 and 4, in an embodiment of the present invention, the through holes for blowing (air-guiding ducts) 60b are arranged toward the first direction a, and are inclined toward the rotation direction of the multiple blades 22. It should be understood that when the multiple blades 22 rotate to output air, the outputted airflow is not arranged along the axial direction of the impeller, but has a certain angle with the circumferential direction of the impeller. Through the above-mentioned inclined arrangement, the through holes 60b for blowing can be adapted to the air output flow of the air-blowing device 20, so that the air-blowing device 20 can efficiently output a large amount of air, thereby the blowing efficiency of the air-blowing device 20 is improved.

For example, the air-passing component 60 is provided with multiple through holes 60b for blowing, and an inclinedly arranged partition 603 is arranged between two adjacent through holes 60b for blowing, so that the inclinedly-arranged through holes 60b for blowing are formed as above mentioned.

As shown in FIG. 1, in an embodiment of the present invention, the apparatus for inflating and blowing further includes an air outlet pipe 54 for the air output of the air pump 10.

The air pump 10 includes a piston assembly 11 and a piston pipe 12. The piston assembly 11 is connected to the piston pipe 12, and the piston pipe 12 is connected to the air outlet hole 52a through the air outlet pipe 54. The piston assembly 11 is provided with a movable piston, the piston is located in the piston pipe 12, and the motor 30 is connected to the piston assembly 11, so as to drive the piston to reciprocate in the piston pipe 12. For example, the motor 30 drives the piston assembly 11 through the meshing of gears, the piston assembly 11 is connected to drive the piston rod, and the piston rod moves in the piston pipe 12.

In an embodiment, the air pump 10 is a piston pump, one side of the piston assembly 11 is an air inlet, and the piston is driven by the motor 30 to reciprocate in the piston pipe 12. For example, the motor 30 can drive a transmission part of the piston assembly 11 to rotate, thereby driving one end of the piston to perform swinging motion. When one end of the piston performs swinging motion, the other end can reciprocate in the piston pipe 12, so as to repeatedly press the air into the piston pipe 12, and then high-pressure air can be outputted through the air outlet pipe 54 and the air outlet hole 52a, so that the high-pressure air is outputted. Of course, in some other embodiments, the air pump 10 may be a diaphragm pump.

For example, one end of the piston pipe 12 is sleeved by the inner wall of the air outlet pipe 54. Thereby, the piston pipe 12 can be stably connected to the air outlet hole 52a through the air outlet pipe 54, so as to achieve stable air output. In the present invention, the air pump 10 may be installed at different positions of the outer shell 40 along the first direction a, according to needs. Thereby, the air pump 10 and the air outlet hole 52a can be connected by simply placing an air outlet pipe 54 with a corresponding (different) length, so as to ensure stable air outlet.

As shown in FIGS. 1 and 2, in an embodiment of the present invention, the piston assembly 11, the piston pipe 12, and the air outlet pipe 54 are arranged in sequence along the first direction a. This arrangement allows the air pump 10 to better fit the shape of the outer shell 40 and be more compactly arranged in the outer shell 40, which is beneficial to the structural integration inside the outer shell 40, further miniaturizing the apparatus for inflating and blowing, so as to facilitate the portability and use of the apparatus.

As shown in FIGS. 1 and 2, in an embodiment of the present invention, both the piston pipe 12 and the air outlet pipe 54 are arranged along the first direction a. By this arrangement, on the one hand, some structures in the air pump 10 and the structures connected to the air pump 10 can better fit the shape of the outer shell 40, so that the structures inside the shell 40 can be more compact, which is beneficial to the structural integration inside the outer shell 40. On the other hand, the air pump 10 outputs air along the first direction a, in combination with the above embodiment that the air output direction of the blowing device 20 is along the first direction a, thereby, the air output of the air pump and the air output of the blowing device can be smoother without affecting each other, which facilitates use.

As shown in FIGS. 1 and 5, in an embodiment of the present invention, an air nozzle structure 50 is provided. The air nozzle structure 50 includes the first interface 51 and second interface 52 as above mentioned, and the second interface 52 is located inside the first interface 51. The first interface 51 is used for connecting to an external to-be-blown device. The second interface 52 is used for connecting to an external to-be-inflated device.

It should be understood that since the air outputted by the air pump 10 is high-pressure air, when the high-pressure air is being outputted through the air outlet hole 52a, high temperature might be generated at the second interface 52, which might easily burn the human body.

Through the air nozzle structure 50 of this embodiment, inflating a to-be-inflated device and blowing air to a to-be-blown device can be performed separately. When an external to-be-inflated device is connected through the second interface 52, and the to-be-inflated device is being inflated by the air pump 10, since the second interface 52 is located inside the first interface 51, a user can be prevented from directly contacting the second interface 52 and being burned by the second interface 52. Moreover, a user can choose a mode according to needs (or in the default mode), and turn on the air-blowing device 20 while the air pump 10 is working, so that the air from the air-blowing device 20 can pass through the blowing hole 51a. Since the second interface 52 is located inside the first interface 51, the air passing through the blowing hole 51a can further dissipate heat and cool the second interface 52, thus, even if a user accidentally touches the second interface 52, burning by the second interface 52 can be avoided, and the user experience can be improved. It should be understood that when a user is inflating a to-be-inflated device, the user can also not turn on the air-blowing device 20, but only turn on the air pump 10, so as to inflate the to-be-inflated device through the air outlet hole 52a.

In addition, in an embodiment of the present invention, an external to-be-blown device may be connected through the first interface 51, and air is blown to the to-be-blown device through the air-blowing device 20. Since the second interface 52 is located inside the first interface 51, a user can choose a mode according to needs (or in the default mode), and turn on the air pump 10 while the air-blowing device 20 is working, so that the air outputted by the air pump 10 and the air outputted by the air-blowing device 20 meet together, which increases the air volume and the blowing air pressure of the blowing device 20, and improves the blowing efficiency. It should be understood that when a user is blowing air to a to-be-blown device, the user can also not turn on the air pump 10, but only turn on the air-blowing device 20, so as to blow air to the to-be-blown device through the blowing hole 51a.

As shown in FIGS. 1 and 5, in an embodiment of the present invention, the air nozzle structure 50 further includes an air outlet pipe 54. One end of the air outlet pipe 54 is connected to the air outlet hole 52a, and an air outlet passage is formed by an inner wall of the air outlet pipe 54 and the air outlet hole 52a. The air outlet passage is used for the air pump 10 to output air. The other end of the air outlet pipe 54 can be connected to the air pump 10, and the air outputted by the air pump 10 can pass through the air outlet passage and enter the to-be-inflated device. A detailed connection method between the air outlet pipe 54 and the air pump 10 can be referred to above. In this embodiment, since the air outlet pipe 54 is connected to the air outlet hole 52a, when the to-be-inflated device is being inflated by the air pump 10, the high-pressure air is outputted through the air outlet passage. Thereby, the high-pressure air will be outputted from the air outlet pipe 54 or the air outlet hole 52a, which reduces the heat directly generated on the second interface 52, and therefore, the temperature of the second interface 52 can be lowered to a certain extent, which avoids burning the user.

For example, one end of the air outlet pipe 54 is flush with the outer surface of the second interface 52. Thereby, the second interface 52 is actually provided around the end of the air outlet pipe 54, and the high-pressure air is actually output from the end of the air outlet pipe 54, which reduces the heat generated on the second interface 52. Therefore, the temperature of the second interface 52 can be reduced to a certain extent, which avoids burning the user.

For example, a stepped protrusion is provided around the air outlet pipe 54. When one end of the air outlet pipe 54 is connected to the air outlet hole 52a, the one end of the air outlet pipe 54 is adapted to and embedded in the air outlet hole 52a, and the stepped protrusion abuts against a side of the second interface 52 wherein the side of the second interface 52 faces toward the inside of the outer shell 40, so as to achieve a stable connection between the air outlet pipe 54 and the air outlet hole 52a.

As shown in FIG. 6, in an embodiment of the present invention, the outer shell 40 is further provided with a fixing assembly 53. One end of the fixing assembly 53 surrounds the second interface 52, and the other end of the fixing assembly 53 may be connected to the inner wall of the first interface 51. Through the fixing assembly 53, the first interface 51 and the second interface 52 can be stably connected, so as to ensure a stable support for the second interface 52, and the second interface 52 can be stably connected to the air pump 10, so as to allow the air pump 10 to output air. Of course, in some other embodiments, the other end of the fixing assembly 53 may be fixedly connected to the outer shell 40, so as to stably support the second interface 52.

As shown in FIG. 6, in an embodiment of the present invention, multiple blowing holes 51a are provided. And the multiple blowing holes 51a are spaced apart from the air outlet hole 52a. Through the multiple blowing holes 51a, the volume of air output can be increased, which achieves a better blowing effect of the air-blowing device 20. Moreover, the multiple blowing holes 51a are all spaced apart from the air outlet hole 52a, so that the inflating and the blowing can work independently in the apparatus for inflating and blowing, which facilitates use. Of course, in some other embodiments, the multiple blowing holes 51a may be in communication with each other, to form one hole, so that the air output is achieved through a big blowing hole.

For example, the space between the second interface 52 and the first interface 51 may be divided into multiple blowing holes 51a by the above-mentioned fixing assembly 53. Thereby, not only the support of the second interface 52 is achieved, but also the blowing holes 51a can be used to output air.

As shown in FIG. 6, in a preferred embodiment of the present invention, the multiple blowing holes 51a are arranged to surround the air outlet hole 52a. For example, the multiple blowing holes 51a are arranged in a surrounding manner, with the air outlet hole 52a as the center. Thereby, each of the multiple blowing holes 51a is able to dissipate heat and cool the second interface 52 when air is being outputted through the air-blowing device 20. Thus, even if a user accidentally touches the second interface 52, burning by the second interface 52 can be avoided, and the user experience can be improved. In addition, this arrangement allows the apparatus for inflating and blowing to output air and/or blow air in a balanced and stable manner.

As shown in FIG. 6, for example, the fixing assembly 53 includes multiple connecting members 531 arranged around the second interface 52 and arranged at intervals. Two ends of the connecting members 531 are respectively connected to the inner wall of the first interface 51 and the outer wall of the second interface 52. The above-mentioned surrounding air outlet holes 51a may be formed by the inner wall of the first interface 51, the multiple connecting members 531, and the outer wall of the second interface 52. Further, the connecting member 531 is wide at two ends and narrow in the middle. Thereby, on the one hand, stable and reliable support for the second interface 52 can be ensured, and on the other hand, the blowing hole 51a can be enlarged as much as possible to ensure that the blowing hole 51a can output a large amount of air. Further, the multiple connecting members 531 are arranged around the second interface 52, and are evenly spaced. For example, the fixing assembly 53 includes three connecting members 531 which surround the second interface 52 at even intervals.

As shown in FIGS. 1 and 6, in an embodiment of the present invention, a air-blowing passage is formed among the outer shell 40, the fixing assembly 53, the blowing hole 51a, and the outer wall of the air outlet pipe 54. The air-blowing passage is used for the air-blowing device 20 to output air. Thereby, the air-blowing passage and the air outlet passage are independent of each other and do not affect each other, which can ensure a better effect of air blowing and air outputting, so as to facilitate the use of the apparatus for inflating and blowing.

For example, the air-blowing passage is in communication with the above-mentioned blowing passage 40b, and the air outputted by the air-blowing device 20 passes through the blowing passage 40b and the air-blowing passage, so as to achieve air output.

As shown in FIG. 6, in an embodiment of the present invention, the first interface 51 is provided with a first end away from the apparatus for inflating and blowing, and the second interface 52 is provided with a second end away from the apparatus for inflating and blowing. The second end is located at a side of the first end wherein the side faces toward the outer shell 40. It can be understood that the second interface 52 is located inside the first interface 51, facing the inside of the apparatus for inflating and blowing. Thereby, it can further prevent the user from directly contacting the second interface 52 and being burned by the second interface 52.

As shown in FIG. 6, in an embodiment of the present invention, the first interface 51 protrudes from the surface of the outer shell 40. Thereby, on the one hand, it is convenient to connect the first interface 51 with the to-be-blown device, and on the other hand, it can achieve the structure in which the second interface is located inside the first interface 51 facing the inside of the apparatus for inflating and blowing.

As shown in FIG. 6, in an embodiment of the present invention, the first interface 51, the second interface 52, and the fixing member may be integrally formed on the outer shell 40. That is to say, when manufacturing the outer shell 40, a part of the structure of the air nozzle structure 50 can be directly formed by injection molding, thereby improving the structural strength of the air nozzle structure 50.

As shown in FIG. 6, in an embodiment of the present invention, the first interface 51 and the second interface 52 are circular interfaces, so as to facilitate the connection with the to-be-blown device and the to-be-inflated device.

As shown in FIG. 7, in an embodiment of the present invention, the air nozzle structure 50 further includes a fixing member. The fixing member is provided on the first interface 51 or the second interface 52, and the fixing member is used for fixedly connecting the to-be-blown device or the to-be-inflated device. Through the fixing member, the air nozzle structure 50 is fixed with an air using device, which helps to blow air to a to-be-blown device or inflate a to-be-inflated device.

As shown in FIG. 7, in an embodiment of the present invention, the fixing member may include a first fixing member 71. The first fixing member 71 is arranged around the outside of the first interface 51 and is used to at least guide the air output by the air-blowing device 20 to the to-be-blown device. This facilitates blowing air to the to-be-blown device. It should be understood that when blowing air to the to-be-blown device, the air-blowing device 20 and the air pump 10 may be turned on at the same time, so as to blow air to the to-be-blown device at the same time, which increases the air volume, or alternatively, the air-blowing device 20 may be turned on individually, to blow air to the to-be-blown device.

As shown in FIG. 7, for example, a protrusion is provided on the outer side of the first interface 51, and an L-shaped snap-in groove is provided on an inner wall of an interface of the first fixing member 71 for connecting to the first interface 51. One end of the L-shaped snap-in groove is in communication with the outside of the interface of the first fixing member 71. When a user connects the first fixing member 71, the interface of the first fixing member 71 can be placed around the outside of the first interface 51 so that the protrusion is placed in the L-shaped snap-in groove, and then the interface of the first fixing member 71 can be rotated so that the protrusion is stuck in the L-shaped snap-in groove. Thereby, the interface of the first fixing member 71 will not be easily detached along the axial direction of the first interface 51, which achieves a stable connection between the first fixing member 71 and the first interface 51. It ensures that the apparatus for inflating and blowing can achieve stable blowing through the first fixing member 71. Of course, in some other embodiments, the interface of the first fixing member 71 and the first interface 51 may be connected through another snap-fitting method, or may be connected through magnetic attraction or threaded connection, which is not limited.

As shown in FIG. 7, for example, the first fixing member 71 has a shape like a trumpet. Specifically, one end of the first fixing member 71 with a larger circumference is fixed to the air nozzle interface, and the other end of the first fixing member 71 with a smaller circumference extends outward, which facilitates air guidance and increases the flow rate of the airflow into the to-be-blown device, so as to improve the blowing efficiency of the apparatus for inflating and blowing.

In another embodiment, the fixing member may include a second fixing member. The second fixing member is arranged in a surrounding manner, and is arranged between the air outlet hole 52a and the blowing hole 51a, and is configured to guide the air outputted by the air pump 10 to the to-be-inflated device. This facilitates inflating the to-be-inflated device. It should be understood that when air is being blown to the to-be-blown device, both the air-blowing device 20 and the air pump 10 can be turned on at the same time, so that the second interface 52 can be cooled during inflating, or alternatively, the air pump 10 may be turned on individually, to inflate the to-be-inflated device.

For example, the inner wall of the second interface 52 or the inner wall of the air outlet pipe 54 is provided with an internal thread, and an interface end of the second fixing member is provided with an external thread. The second fixing member and the air nozzle structure 50 are connected by threaded connection, so as to achieve a stable connection between the second fixing member and the air nozzle structure 50. It ensures that the apparatus for inflating and blowing can perform a stable inflating through the second fixing member. Of course, in some other embodiments, the interface of the second fixing member and the second interface 52 may be connected by snap-fitting or magnetic attraction, which is not limited.

For example, the second fixing member has a shape like a trumpet. Specifically, one end of the second fixing member with a larger circumference is fixed to the air nozzle structure 50, and the other end of the second fixing member with a smaller circumference extends outward, which facilitates air guidance and increases the flow rate of the airflow into the to-be-inflated device, so as to improve the inflating efficiency of the apparatus for inflating and blowing.

In addition, the present invention may provide a set of fixing members, such as a kit including the first fixing member 71 and the second fixing member 72. When an external to-be-blown device is connected, the first fixing member 71 is used to connect the to-be-blown device and the apparatus for inflating and blowing of the present invention. When an external to-be-inflated device is connected, the second fixing member 72 is replaced with and is used to connect the to-be-inflated device and the apparatus for inflating and blowing of the present invention.

In the apparatus for inflating and blowing of the present invention, the fixing member may be connected to the to-be-blown device or the to-be-inflated device, by snap-fitting or threaded connection. Thereby, a stable connection between the fixing member and the to-be-blown device or the to-be-inflated device is ensured, so as to achieve stable blowing and inflating.

As shown in FIGS. 1 and 2, in an embodiment of the present invention, the apparatus for inflating and blowing further includes a switch (not shown in the figure). The switch is located on the outer shell 40. The switch is configured to control the apparatus for inflating and blowing, to enter different modes. For example: inflating mode, blowing mode, or inflating-and-blowing mode. Through the provided switch, a user can select a use mode for the apparatus for inflating and blowing, which improves the user experience. Therein, in the inflating mode, the motor 30 only drives the air pump 10 to operate, and does not drive the air-blowing device 20 to operate. The apparatus for inflating and blowing can be used for inflating the to-be-inflated device; in the blowing mode, the motor 30 only drives the air-blowing device 20 to operate, and the air pump 10 does not operate. The apparatus for inflating and blowing can be used for blowing air to the to-be-blown device; in the inflating-and-blowing mode, the motor 30 drives the air pump 10 and the air-blowing device 20 to operate at the same time. The apparatus for inflating and blowing can be used for blowing air to the to-be-blown device, and at the same time, the air output is increased by the air pump 10. Or, the apparatus for inflating and blowing can be used for inflating the to-be-inflated device. While the inflating is performed by the air pump 10, the air-blowing device 20 can cool down the air nozzle structure 50 by blowing air.

As shown in FIGS. 1 and 2, in an embodiment of the present invention, the apparatus for inflating and blowing further includes an energy storage module (not shown in the figure) and an output interface for emergency starting power supply (not shown in the figure). The energy storage module is located in the outer shell 40, and the output interface for emergency starting power supply is electrically connected to the energy storage module. The energy storage module can store electric energy. When needed, the output interface for emergency starting power supply can be used to supply emergency power to the vehicle, for example, for emergency starting of the vehicle. This makes the apparatus for inflating and blowing more convenient to carry and use. It should be understood that the energy storage module of the present invention may be used to supply power to the motor 30, so as to enable the motor 30 to perform corresponding work.

As shown in FIGS. 1 and 2, in an embodiment of the present invention, the apparatus for inflating and blowing further includes one or more selected from a USB interface, an AC socket, a DC interface, and a cigarette lighter socket. The USB interface, the AC socket, the DC interface, the output interface for emergency starting power supply, and/or the cigarette lighter socket is/are electrically connected to the energy storage module. Various electrical connection interfaces can be used to supply power to some other electronic devices. According to different electronic devices, the types of electrical connection interfaces can be changed correspondingly, so as to achieve multi-functional power supply.

The various electrical connection interfaces as above can be located on the outer shell 40, which facilitates connection and use.

As shown in FIGS. 1 and 2, in an embodiment of the present invention, the apparatus for inflating and blowing further includes an inverter module (not shown in the figure). The energy storage module is connected to the electrical connection interface of the energy storage device through the inverter module, so as to provide alternating current to the electrical connection interface.

As shown in FIGS. 1 and 2, in an embodiment of the present invention, the apparatus for inflating and blowing further includes a charging interface (not shown in the figure). The charging interface is electrically connected to the energy storage module. The charging interface is located on the outer shell 40. The charging interface is used for charging the energy storage module, which facilitates the charging of the energy storage module and achieves a convenient use of the apparatus for inflating and blowing.

As shown in FIGS. 1 and 2, in an embodiment of the present invention, the apparatus for inflating and blowing is further provided with a main control board (not shown in the figure). The main control board is connected to electrical components such as various electrical connection interfaces, charging interface, energy storage module, switch, motor 30, etc., so as to achieve corresponding control functions.

As shown in FIGS. 1 and 2, in an embodiment of the present invention, the outer shell 40 includes a first shell 41 and a second shell 42. Both the first shell 41 and the second shell 42 extend along the first direction a. The first shell 41 is provided with a mounting groove 41a. The above-mentioned air nozzle structure 50 and air inlet 40a are both provided on the first shell 41. When installing the air-blowing device 20, the motor 30, and the air pump 10, the air pump 10 and the motor 30 may be fixed to the bottom of the mounting groove 41a with screws. The air-passing component 60 may be installed at one end of the motor 30 wherein the end of the motor 30 is close to the air inlet 40a, and the mounting hole 60a of the air-passing component 60 is located around the end of the motor 30. The motor 30 is connected to the air-blowing device 20 through the second output shaft, and supports the air-blowing device 20. The second shell 42 covers the opening of the mounting groove 41a and is connected to the first shell 41, so that the air-blowing device 20, motor 30, and air pump 10 are installed inside the outer shell 40.

As shown in FIGS. 1 and 2, in an embodiment of the present invention, the above-mentioned main control board, energy storage module, etc. are installed inside the outer shell 40 and may be located at the blowing passage 40b. Thereby, when air is being outputted by the air-blowing device 20, the blowing air can also cool down the main control board, the energy storage module, etc., which ensures the stable operation of the apparatus for inflating and blowing.

For example, the main control board, the energy storage module, etc. may be installed at a side of the motor 30 and/or the air pump 10 wherein the side is away from the bottom of the mounting groove 41a, and located at a side of the air-passing component 60 wherein the side is away from the air-blowing device 20, which ensures the stable air output of the air-blowing device 20 and also the stable installation of the main control board, the energy storage module, etc. At the same time, this arrangement can also make full use of the remaining space in the outer shell 40 and does not require additional space for installation, making the internal structure of the apparatus for inflating and blowing more compact, which facilitates the portability and use of the apparatus.

Another embodiment of the present invention is shown in FIGS. 9a and 9b. The difference between this embodiment and the embodiment shown in FIGS. 1 and 2 is that the apparatus for inflating and blowing shown in FIGS. 9a and 9b uses an L-shaped air pump. As shown in FIG. 9b, the direction a of the driving shaft of the motor 30 driving the air pump (such as the direction a of the motor output shaft 301 driving the piston assembly 11 as shown in FIG. 8) and the movement direction b of the piston rod of the air pump (that is, the longitudinal direction of the piston pipe 12) are perpendicular to each other, that is, they are L-shaped. This is the characteristic of a L-shaped air pump on the market.

In the embodiment shown in FIGS. 9a and 9b, the air-blowing device 20, the motor 30, and the air pump 10 of the present invention are all located inside the housing 40. The housing 40 is provided with an air inlet 40a. The air-blowing device 20 (for example, an impeller 20, as shown in FIG. 4) is located close to the air inlet 40a, and is driven by the motor 30. The same motor 30 is used not only for driving the air-blowing device 20 but also for driving the air pump 10.

For example, as shown in FIG. 8, the motor 30 is drivingly connected to the air-blowing device 20 and to the air pump 10, through the output ends 302 and 301 located on the left and right sides, respectively. For example, the output shaft 302 and the output shaft 301 may come from the output of the same rotating shaft in the motor 30. In another embodiment, the motor 30 may be drivingly connected to the air-blowing device 20 and the air pump 10 in sequence, through an output end on the same side (for example, through the output end 301 on the left side).

In this embodiment, it is preferred that the air-blowing device 20, the motor 30, and the air pump 10 are arranged in sequence along the first direction a (the length or width direction of the housing 40; in FIG. 9b, the first direction a is the width direction). Nevertheless, since the air pump itself is L-shaped, the air-blowing device 20, the motor 30, and the air pump 10 form an L-shaped structure as a whole.

A blowing passage 40b is provided inside the housing 40.

Preferably, a part of the blowing passage 40b is located between the air pump 10 and the housing 40. More preferably, a space between the air pump 10 and the housing 40 forms a part of the blowing passage 40b.

Therein, the housing 40 may refer to the outer shell frame of the apparatus for inflating and blowing, or it may be the inner shell frame (for example, the inner shell frame 410 in FIG. 9b). As shown in FIG. 9b, the blowing passage 40b may be surrounded and formed by a part of the outer shell frame 40 and a part of the inner shell frame 410.

Moreover, preferably, a part of the blowing passage 40b is located between the motor 30 and the housing 40. More preferably, a space between the motor 30 and the housing 40 forms a part of the blowing passage 40b.

More preferably, the apparatus for inflating and blowing further includes an air-passing component 60 (as shown in FIG. 3). The air-passing component 60 is located in the air outlet direction of the air-blowing device 20. The air-passing component 60 is beneficial for guiding the airflow from the air-blowing device 20 into the blowing passage 40b. In order to make the structure more compact, the air-passing component 60 is preferably so installed as to surround at least a part of the motor 30 (or the air pump 10). For example, the air-passing component 60 is provided with a mounting hole 60a, and at least one selected from the motor 30 and the air pump 10 is fixed in the mounting hole.

The outer shell 40 is provided with an air outlet 50. The air outlet 50 may include a first interface 51 and a second interface 52. The first interface 51 is used for connecting to an external to-be-blown device, and the second interface 52 is used for connecting to an external to-be-inflated device. The outlet end of the air pump 10 may be connected with an air outlet pipe 54.

In this embodiment, the parts that may be the same as those in the embodiments of FIGS. 1 and 2 will not be further described in detail.

It is particularly noteworthy that, due to the arrangement of the L-shaped air pump, the overall blowing passage 40b is also L-shaped. For example, a part of the blowing passage 40b is the airflow passage formed by the space between the motor 30 and the housing 40, and another part of blowing passage 40b is the airflow passage formed by the space between the piston pipe 12 and the housing 40. The two parts are perpendicular to each other and are L-shaped.

Correspondingly, the air outlet 50 (the first interface 51 and the second interface 52) may be provided on a surface of the housing wherein the surface is perpendicular to the air inlet 40a. Therefore, the overall blowing passage presents an L-shape.

In addition, as shown in FIG. 9b, the apparatus for inflating and blowing may be provided with an energy storage module 90, a main control board 80, and the like, inside the outer shell. For example, the energy storage module 90 and/or the main control board 80 may be located in a space/corner outside the L-shaped blowing passage 40b (for example, a space/corner separated by the inner shell frame 410 and thus outside the blowing passage 40b).

The design of L-shaped structure in this embodiment can effectively utilize the two-dimensional space, and prevent one dimension of the finished product from being too long, which may be beneficial for reducing the storage size.

The above are only some preferred embodiments of the present invention, and will not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention and the drawings under the application concept of the present invention, or by directly/indirectly applying the present invention in another related technical field, shall fall within the patent protection scope of the present invention.
