DETAILED DESCRIPTION

Before any examples of this application are explained in detail, it is to be understood that this application is not limited to its application to the structural details and the arrangement of components set forth in the following description or illustrated in the above drawings.

In this application, the terms “comprising”, “including”, “having” or any other variation thereof are intended to cover an inclusive inclusion such that a process, method, article or device comprising a series of elements includes not only those series of elements, but also other elements not expressly listed, or elements inherent in the process, method, article, or device. Without further limitations, an element defined by the phrase “comprising a . . . ” does not preclude the presence of additional identical elements in the process, method, article, or device comprising that element.

In this application, the term “and/or” is a kind of association relationship describing the relationship between associated objects, which means that there can be three kinds of relationships. For example, A and/or B can indicate that A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character “/” in this application generally indicates that the contextual associated objects belong to an “and/or” relationship.

In this application, the terms “connection”, “combination”, “coupling” and “installation” may be direct connection, combination, coupling or installation, and may also be indirect connection, combination, coupling or installation. Among them, for example, direct connection means that two members or assemblies are connected together without intermediaries, and indirect connection means that two members or assemblies are respectively connected with at least one intermediate members and the two members or assemblies are connected by the at least one intermediate members. In addition, “connection” and “coupling” are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

In this application, it is to be understood by those skilled in the art that a relative term (such as “about”, “approximately”, and “substantially”) used in conjunction with quantity or condition includes a stated value and has a meaning dictated by the context. For example, the relative term includes at least a degree of error associated with the measurement of a particular value, a tolerance caused by manufacturing, assembly, and use associated with the particular value, and the like. Such relative term should also be considered as disclosing the range defined by the absolute values of the two endpoints. The relative term may refer to plus or minus of a certain percentage (such as 1%, 5%, 10%, or more) of an indicated value. A value that did not use the relative term should also be disclosed as a particular value with a tolerance. In addition, “substantially” when expressing a relative angular position relationship (for example, substantially parallel, substantially perpendicular), may refer to adding or subtracting a certain degree (such as 1 degree, 5 degrees, 10 degrees or more) to the indicated angle.

In this application, those skilled in the art will understand that a function performed by an assembly may be performed by one assembly, multiple assemblies, one member, or multiple members. Likewise, a function performed by a member may be performed by one member, an assembly, or a combination of members.

In this application, the terms “up”, “down”, “left”, “right”, “front”, and “rear” and other directional words are described based on the orientation or positional relationship shown in the drawings, and should not be understood as limitations to the examples of this application. In addition, in this context, it also needs to be understood that when it is mentioned that an element is connected “above” or “under” another element, it can not only be directly connected “above” or “under” the other element, but can also be indirectly connected “above” or “under” the other element through an intermediate element. It should also be understood that orientation words such as upper side, lower side, left side, right side, front side, and rear side do not only represent perfect orientations, but can also be understood as lateral orientations. For example, lower side may include directly below, bottom left, bottom right, front bottom, and rear bottom.

In this application, the terms “controller”, “processor”, “central processor”, “CPU” and “MCU” are interchangeable. Where a unit “controller”, “processor”, “central processing”, “CPU”, or “MCU” is used to perform a specific function, the specific function may be implemented by a single aforementioned unit or a plurality of the aforementioned unit.

In this application, the term “device”, “module” or “unit” may be implemented in the form of hardware or software to achieve specific functions.

In this application, the terms “computing”, “judging”, “controlling”, “determining”, “recognizing” and the like refer to the operations and processes of a computer system or similar electronic computing device (e.g., controller, processor, etc.).

Technical solutions proposed in the present application are described in detail in conjunction with drawings and examples.

A power tool shown in FIG. 1 is used for a user to operate to perform a tool function. In this example, the power tool is powered by a battery pack 25. The power tool is an electric tool. In an example, the electric tool is a vacuum cleaner 100, and the user uses the vacuum cleaner 100 to work on areas such as a ground, carpet, factory, car, narrow corners, etc., to absorb dust in these areas.

As shown in FIG. 1, the vacuum cleaner 100 includes a vacuum cleaner body 20, a suction pipe assembly 30, and a dust accessory 40. The vacuum cleaner body 20 includes a housing assembly 21, a power assembly 22 (as shown in FIG. 7) and a power supply device, and the power supply device is the battery pack 25 for supplying power to the power assembly 22. The vacuum cleaner body 20 and the suction pipe assembly 30 can be considered as a tool body of the electric tool, the dust accessory 40 can be considered as a tool accessory of the electric tool, and the tool accessory is detachably mounted to the tool body.

In order to facilitate the description of the technical solution of the present application, the up, down, front, rear, left and right as shown by the arrows in FIGS. 1 and 2 are also defined. The battery pack 25 is coupled to the housing assembly 21 in a direction from rear to front.

The suction pipe assembly 30 is detachably mounted to a front side of the vacuum cleaner body 20. The suction pipe assembly 30 includes a first connection end 30a connected to the housing assembly 21 and a second connection end 30b opposite to the first connection end 30a, and the dust accessory 40 is detachably mounted to the second connection end 30b.

Normally, the user rarely disassemble the suction pipe assembly 30, but often replace dust accessories with different structures. Therefore, the vacuum cleaner 100 of the present application also provides different types of dust accessories for the user to replace corresponding dust accessory 40 according to work needs. For example, a first dust accessory 41 shown in FIG. 1 can be used by the user to absorb dust on flat surfaces such as ground and carpet. As shown in FIG. 4, the vacuum cleaner 100 of the present application also provides a second dust accessory 50, and the second dust accessory 50 is usually used by the user to absorb dust in narrow areas or gaps.

As shown in FIGS. 1 and 6, the housing assembly 21 includes an upper housing 211 and a lower housing 212, and the upper housing 211 and the lower housing 212 are connected to form a first accommodating chamber 21a for accommodating dust or a dust bag. The upper housing 211 includes an outer housing 211a and a partition 211b, and the partition 211b is connected to the outer housing 211a to form a second accommodating chamber for accommodating the power assembly 22. The outer housing 211a is an upper surface of the upper housing 211, and the outer housing 211a is formed with a coupling portion 211c for coupling with the battery pack 25. The partition 211b is disposed between the outer housing 211a and the lower housing 212. As shown in FIGS. 1 and 6, the housing assembly 21 includes a locking assembly 213 for connecting the upper housing 211 and the lower housing 212, and the user can connect or separate the upper housing 211 and the lower housing 212 by operating the locking assembly 213. For example, when the user needs to clean the dust or dust bag in the first accommodating chamber 21a, the user can use the locking assembly 213 to separate the upper housing 211 from the lower housing 212.

The coupling portion 211c is arranged at a rear end of the upper housing 211, and the suction pipe assembly 30 is detachably mounted to a front end of the upper housing 211, so that the balance of the vacuum cleaner 100 can be improved.

The suction pipe assembly 30 includes a first connection portion 31 provided at the first connection end 30a and a second connection portion 32 provided at the second connection end 30b, the first connection portion 31 is used to connect the first connection end 30a of the suction pipe assembly 30 to the housing assembly 21, and the second connection portion 32 is used to connect the second connection end 30b of the suction pipe assembly 30 to the dust accessory 40. The suction pipe assembly 30 includes a connection pipe 33 provided between the first connection portion 31 and the second connection portion 32, and the connection pipe 33 is used to increase the length of the suction pipe assembly 30. In this example, the connection pipe 33 is a hose, so that the user can operate the suction pipe assembly 30 more freely to adapt to different working environments.

In this example, the first dust accessory 41 includes a first dust accessory body 411 and an extension rod assembly 412. It can be understood that the first dust accessory 41 is usually used for the user to absorb dust on the ground. By providing the extension rod assembly 412, the user can avoid bending or squatting to operate, thereby improving the comfort of operation. One end of the extension rod assembly 412 is connected to the first dust accessory body 411, and the other end is connected to the second connection portion 32. The extension rod assembly 412 includes a first extension rod 412a and a second extension rod 412b, so that the user can install one or two extension rods according to their height and work needs. As shown in FIGS. 2 to 4, when the user needs to replace the first dust accessory 41 with the second dust accessory 50, the user can remove the first dust accessory 41 and then install the second dust accessory 50 to the second connection portion 32.

As shown in FIG. 3, a second mounting portion 211d is provided on the upper housing 211. When the second dust accessory 50 is not in use, it can be mounted to the upper housing 211 through the second mounting portion 211d. The second mounting portion 211d is specifically a mounting slot extending in a front-rear direction, and the second dust accessory 50 can be inserted into the mounting slot in the front-rear direction. The mounting slot is provided on a left side of the upper housing 211.

As shown in FIG. 4, when the second dust accessory 50 is used but the first dust accessory 41 is not used, the first dust accessory 41 can be mounted on the housing assembly 21. In this example, a first mounting portion 214 for mounting the first dust accessory 41 is provided on the housing assembly 21, the first mounting portion 214 includes a clamping portion 214a for mounting the first dust accessory body 411, and the clamping portion 214a is provided on a rear side of the housing assembly 21 and provided on a rear side of the lower housing 212. The first mounting portion 214 further includes a mounting assembly 214b provided on a bottom surface of the housing assembly 21, and the two extension rods of the extension rod assembly 412 can be mounted to the bottom surface through the mounting assembly 214b.

In this example, the vacuum cleaner 100 is a movable vacuum cleaner 100, the vacuum cleaner body 20 further includes a walking assembly 23 mounted to the housing assembly 21, and the walking assembly 23 supports the vacuum cleaner body 20 on the ground. Through the walking assembly 23, a distance can be provided between the bottom surface of the housing assembly 21 and the ground, so that a mounting space for setting the mounting assembly 214b and for mounting the extension rod assembly 412 can be formed between the bottom surface and the ground. In this way, without increasing the height of the vacuum cleaner 100, the space is reasonably used to mount the extension rod assembly 412.

The walking assembly 23 includes front walking wheels 231 and rear walking wheels 232, and the front walking wheels 231 are universal wheels.

As shown in FIG. 5, the vacuum cleaner 100 further includes a third dust accessory 42 and a fourth dust accessory 43, and the third dust accessory 42 is a relatively small suction nozzle and the fourth dust accessory 43 is a brush. The vacuum cleaner 100 further includes an adapter 44, which is used to connect to the second connection portion 32 of the suction pipe assembly 30 so that the suction pipe assembly 30 can be connected to dust accessories with standard interfaces suitable for more countries, markets or users.

The upper housing 211 further includes a cover 211, the upper housing 211 is formed with a third accommodating chamber 21b for installing the third dust accessory 42, the fourth dust accessory 43 and the adapter 44, and the cover 211 covers the third accommodating chamber 21b. The cover 211 has a closed state as shown in FIG. 3 and an open state as shown in FIG. 5. In this example, the cover 211 is made of a transparent or translucent material, which makes it convenient for the user to find the dust accessories they want to use more quickly.

As shown in FIG. 3, the upper housing 211 is further provided with a handle 211e, and the user can lift the vacuum cleaner 100 by the handle 211e to move it. The upper housing 211 is further provided with a third mounting portion 211f, which is used to store the relatively long hose. The handle 211e extends in a left-right direction, two third mounting portion 211fs are provided, and the two third mounting portion 211fs are respectively disposed at the two ends of the handle 211e, so that the hose can be snapped to the third mounting portion 211f in a ring shape.

As shown in FIGS. 7 and 8, the power assembly 22 includes: a motor 221 and a fan 222, the motor 221 drives the fan 222 to rotate, and the motor 221 and the fan 222 are both arranged in the housing assembly 21. The fan 222 serves as an output member of the electric tool, and the motor 221 drives the output member to rotate. In this example, the motor 221 is an electric motor that can drive the fan 222 to rotate. When the fan 222 is driven by the motor 221 to rotate, a high-speed airflow can be generated that flows through the dust accessory 40, the suction pipe assembly 30, and the housing assembly 21 in sequence. The housing assembly 21 includes an air duct assembly 215, and the motor 221 and the fan 222 are arranged in the air duct assembly 215. The air duct assembly 215 is formed with a volute channel, and the air duct assembly 215 includes an air duct inlet 215a and an air duct outlet 215b. After the airflow enters the volute channel from the air duct inlet 215a, it passes through the motor 221 and the fan 222, then flows out from the air duct outlet 215b, and then enters into the first accommodating chamber 21a. The vacuum cleaner body 20 includes a filter assembly 24, which is used to filter dust in the airflow. The airflow entering the first accommodating chamber 21a enters the filter assembly 24 for filtration, so that the dust is retained in the first accommodating chamber 21a, and the airflow flows out of the housing assembly 21 after passing through the filter assembly 24 and enters the outside air.

As shown in FIGS. 2 and 7, the vacuum cleaner body 20 also includes a dust shaking assembly 26. When the vacuum cleaner body 20 is used for a long time, a lot of dust may be adsorbed on the filter assembly 24, which will reduce the wind force of the vacuum cleaner 100 and affect the dust collection efficiency. At this time, the user can operate the dust shaking assembly 26 to make the dust on the filter assembly 24 be patted down. Specifically, the dust shaking assembly 26 includes an operating member 261, a patting member 262 and a wind blocking member 263. The operating member 261 is used for user operation, the patting member 262 is used to pat the filter assembly 24, and the wind blocking member 263 is a protrusion set on the upper housing 211. The operating member 261 is connected to the patting member 262 to form a lever structure. When the operating member 261 is pressed, the patting member 262 is lifted, and when the operating member 261 is released, the patting member 262 sinks to pat the filter assembly 24. During operation of the vacuum cleaner 100, the user first connects one end of the extension rod assembly 412 installed on the suction pipe assembly 30 to the protrusion on the upper housing 211 as show in the dotted line in FIG. 3, so that an airflow channel 513 of the entire vacuum cleaner 100 can form a vacuum environment and a large patting force can be formed. Then, the user presses the operating member 261 to make the patting member 262 pat the filter assembly 24.

As shown in FIGS. 3 and 7, the vacuum cleaner body 20 further includes a circuit board assembly 27 and a control assembly 28. The circuit board assembly 27 is connected to the motor 221 to control the operation of the motor 221, and the control assembly 28 is used for the user to operate to control the vacuum cleaner 100. The control assembly 28 includes a power switch 281, a first start switch 282, a speed regulating element 283, and a first acceleration operating element 284. By operating the power switch 281, the user can power on the vacuum cleaner body 20, the battery pack 25 can supply power to a power system in the vacuum cleaner 100, but the motor 221 does not start. When the user operates the first start switch 282, the motor 221 rotates and the vacuum cleaner 100 starts to work to vacuum. The speed regulating element 283 is operated by the user to adjust the speed of the motor 221 so that the vacuum cleaner 100 has different suction forces. In this example, the speed regulating element 283 has two gears that respectively enable the motor 221 to have different speeds: a low speed gear and a high speed gear. Of course, it can be understood that in other examples, the speed regulating element 283 can have three or more gears. When the user operates the first start switch 282, the speed regulating element 283 is in the low speed gear by default. When the user needs to increase the suction force of the vacuum cleaner 100, the user can press the speed regulating element 283 to switch the vacuum cleaner 100 from the low speed gear to the high speed gear. In this example, when the speed regulating element 283 is in the low speed gear, the motor 221 has a first speed, and when the speed regulating element 283 is in the high speed gear, the motor 221 has a second speed, which is greater than the first speed. In this example, the control assembly 28 further includes the first acceleration operating element 284, and when the user operates the first acceleration operating element 284, the first acceleration operating element 284 controls the motor 221 to run at a maximum speed, which is greater than the first speed and greater than the second speed.

As shown in FIG. 9, a pressure relief port 32a and a pressure relief member 34 are further provided on the second connection portion 32 of the suction pipe assembly 30. The pressure relief member 34 is rotatably connected to the second connection portion 32 to open or close the pressure relief port 32a. Normally, the pressure relief member 34 closes the pressure relief port 32a, which does not affect the suction force of the vacuum cleaner 100. However, when the vacuum cleaner 100 is sucking dust on the carpet, the dust accessory 40 is easily sucked together with the carpet, and it is difficult for the user to separate the dust accessory 40 from the carpet. At this time, the user can open the pressure relief port 32a by rotating the pressure relief member 34, so that the airflow enters the suction pipe assembly 30 and the dust accessory 40 from the pressure relief port 32a, so that the dust accessory 40 can be automatically separated from the carpet.

As shown in FIGS. 1, 4 and 5, the vacuum cleaner 100 further includes a remote controller 60 for controlling the operation of the vacuum cleaner 100. The remote controller 60 is separately provided from the vacuum cleaner body 20, and is used to control the operation of the vacuum cleaner body 20 by operating the remote controller 60. In this way, when the user needs to start or turn off the vacuum cleaner 100 at any time during work, there is no need to bend down or stop the operation of the hand to operate the control assembly 28 located on the housing assembly 21. In this example, the remote controller 60 can be installed on the second connection portion 32 of the suction pipe assembly 30. We know that when the user is working, the user's hand is usually held on the second connection portion 32. In this way, the remote controller 60 is installed on the second connection portion 32, and the user's hand holding the second connection portion 32 can operate the remote controller 60 at any time without separating from the second connection portion 32, thereby improving the convenience of operation and improving work efficiency. For the electric tool, the remote controller 60 is used to control the operation of the tool body, and the remote controller 60 can be detachably installed to the tool body or the tool accessory.

In this example, the remote controller 60 is detachably mounted on the second connection portion 32 of the suction pipe assembly 30, and the remote controller 60 and the circuit board assembly 27 form a remote communication connection. For example, the remote controller 60 may be provided with a wireless communication module for forming a wireless communication connection with the circuit board assembly 27. The remote controller 60 is detachably mounted to the suction pipe assembly 30 such that there are no wires between the remote controller 60, the dust accessory 40, and the suction pipe assembly 30.

As shown in FIG. 5, the remote controller 60 may also be placed in the third accommodating chamber 21b formed by the cover 211 and the upper housing 211, so as to prevent the remote controller 60 from being lost when not in use and to prevent water from entering the remote controller 60.

The remote controller 60 is mounted to a fourth mounting portion 35 formed on the second connection portion 32 through a magnetic member 68, and the fourth mounting portion 35 is provided with a member 351 such as iron, nickel, cobalt, etc. that can be adsorbed by the magnetic member 68. Similarly, the remote controller 60 can also be mounted in the third accommodating chamber 21b through the magnetic member 68. The magnetic member 68 is disposed at a lower surface of the remote controller 60. In this way, the remote controller 60 can be effectively prevented from being lost due to being placed at random.

The remote controller 60 includes a remote controller housing 61, a second start switch 62, a second acceleration operating element 63, and an energy storage element 64. The second start switch 62 and the second acceleration operating element 63 are mounted on the remote controller housing 61 for the user to operate. The function of the second start switch 62 is the same as that of the first start switch 282 of the vacuum cleaner body 20, so that the user can operate to start or shut down the vacuum cleaner 100. The function of the second acceleration operating element 63 is also the same as that of the first acceleration operating element 284, so that the user can operate to control the motor 221 to run at the maximum speed. The energy storage element 64 is arranged in the remote controller housing 61 to store electrical energy for powering the remote controller 60. In this way, the remote controller 60 can be disconnected electrically from the vacuum cleaner body 20 without the need for power supply through the battery pack 25.

As shown in FIGS. 9 to 13, the second dust accessory 50 is detachably connected to an end of the suction pipe assembly 30 away from the housing assembly 21, that is, is mounted on the second connection portion 32 of the second connection end 30b of the suction pipe assembly 30.

The second dust accessory 50 includes a second dust accessory body 51, the second dust accessory body 51 includes an air inlet 511, an air outlet 512, and an airflow channel 513, and the airflow channel 513 connects the air inlet 511 and the air outlet 512. The airflow enters the airflow channel 513 from the air inlet 511, and then enters the suction pipe assembly 30 through the air outlet 512.

The remote controller 60 further includes a lighting element 65 and a lighting switch 66, which are mounted to the remote controller housing 61. When the user needs to illuminate a working area through the lighting element 65, the lighting switch 66 can be operated to light up the lighting element 65. In this example, the energy storage element 64 is electrically connected to the lighting element 65 to supply power to the lighting element 65.

As shown in FIG. 15, a charging interface 67 is provided on the remote controller housing 61, and the charging interface 67 is configured to charge the energy storage element 64, which may be a rechargeable battery. The charging interface 67 may be a USB interface. The charging interface 67 may be a type-c interface.

The second dust accessory 50 further includes a light guide member 52, which is mounted to the second dust accessory body 51. When the remote controller 60 is mounted to the fourth mounting portion 35 on the second connection portion 32, and the second dust accessory 50 is mounted to the second connection portion 32, the light guide member 52 can guide at least part of the light emitted by the lighting element 65. In this example, the light guide member 52 can guide the light emitted by the lighting element 65, so that when the second dust accessory 50 is working in a narrow area, the light guide member 52 can guide the light emitted by the lighting element 65 to the narrow area to illuminate the narrow area, thereby facilitating the work of the user.

In this example, the length L of the second dust accessory body 51 is greater than or equal to 20 cm. In this way, the second dust accessory 50 can be easily inserted into a narrow gap. The air inlet 511 of the second dust accessory body 51 is a flat mouth, and the air outlet 512 is a round mouth. The cross-sectional area of the flat mouth is smaller than that of the round mouth, so that the airflow can be accelerated to enter the airflow channel 513 formed by the second dust accessory body 51. The second dust accessory body 51 is made of transparent or translucent material, which can not only not hinder the observation of the narrow area, but also enable the user to see the dust entering the airflow channel 513.

The light guided by the light guide member 52 comes from the lighting element 65 on the remote controller 60, and there is no need to set the lighting element 65 on the second dust accessory 50 or the suction pipe assembly 30, thereby making the structure simpler. If the lighting element 65 is set on the second dust accessory 50 or the suction pipe assembly 30, not only will the structure of the second dust accessory 50 and the suction pipe assembly 30 become very complicated, but it is also necessary to consider that the lighting element 65 on the second dust accessory 50 and the suction pipe assembly 30 need to be connected to the vacuum cleaner body 20 to obtain electrical energy. In the present application, the light guided by the light guide member 52 comes from the remote controller 60, and the remote controller 60 supplies power to the lighting element 65 through its own power supply, so there is no need to set up additional wires connected to the vacuum cleaner body 20, and the structure is simple. Moreover, the remote controller 60 can be detached from the suction pipe assembly 30 at will, thereby increasing the scope of application. Furthermore, when using other dust accessories, the remote controller 60 can also provide lighting to the working area through the lighting element 65.

For the electric tool, the light guide member 52 can be mounted on the tool body or the tool accessory. In this way, when the remote controller 60 is mounted on the tool body or the tool accessory, the light guide member 52 can guide at least a part of the light emitted by the lighting element 65.

In other examples, in order to realize the lighting function, the remote controller 60 used to emit light to the light guide member 52 can also be replaced by an independent lighting device, which can be detachably mounted on the suction pipe assembly 30 like the remote controller 60, such that there are no wires between the lighting device, the dust accessory 50, and the suction pipe assembly 60. The only difference is that the remote controller 60 has the function of controlling the operation of the vacuum cleaner body 20, while the lighting device does not have the function of controlling the operation of the vacuum cleaner body 20. The main function of the lighting device is to emit light. In this way, when the lighting device is mounted on the suction pipe assembly 30 and the dust accessory 40 is mounted on the suction pipe assembly 30, the light emitted by the lighting device is incident on the light guide member 52, and the light guide member 52 guides at least part of the light emitted by the lighting element 65. It can be understood that the lighting device can have an energy storage element 64 for energy storage like the remote controller 60, and the energy storage element 64 is arranged in a device housing to power the lighting element 65. The device housing can also be provided with a charging interface 67 for charging the energy storage element 64 and a lighting switch 66 for lighting the lighting element 65. The specific structure of the lighting device will not be repeated here. The structure and function of the remote controller 60 that can be applied to the lighting device can be applied to the lighting device, and the specific details will not be repeated here.

In this example, the second dust accessory body 51 extends substantially along a first straight line 101, and the second dust accessory body 51 includes a round tube portion 514 connected to the second connection portion 32 and a flat mouth portion 515 away from the second connection portion 32. The light guide member 52 extends substantially along the length direction of the second dust accessory body 51.

In this example, the light guide member 52 is a light guide rod, and the cross-section of the light guide rod perpendicular to the length direction thereof is substantially circular. The light guide member 52 includes a first end 521 and a second end 522, and the second end 522 is arranged opposite to the first end 521. A light incident surface 521a is formed at the first end 521, and the light incident surface 521a is used to introduce the light emitted by the lighting element 65 into the light guide member 52. A light exit surface 522a is formed at the second end 522, and the light exit surface 522a is used to output the light. The second end 522 extends to the air inlet 511 of the second dust accessory 50 to guide the light to a front end of the second dust accessory 50. The second end 522 of the light guide member 52 is substantially aligned with the air inlet 511, so that the light emitted by the lighting element 65 can be guided to the front end of the second dust accessory 50.

The second connection portion 32 is also provided with a limiting member 36. When the remote controller 60 is mounted on the second connection portion 32, the position of the remote controller 60 on the second connection portion 32 is usually fixed. At this time, installing the second dust accessory 50 may make a circumferential position of the second dust accessory 50 relative to the second connection portion 32 uncertain, so that the light emitted by the lighting element 65 cannot be accurately directed to the light incident surface 521a of the light guide member 52. The limiting member 36 can limit the second dust accessory 50 to have a preset circumferential position relative to the suction pipe assembly 30. In this way, when the second dust accessory 50 is mounted to the preset circumferential position, the light incident surface 521a of the light guide element can face the lighting element 65.

As shown in FIGS. 11 and 14, a groove 521b is provided at the first end 521 of the light guide member 52, and the light incident surface 521a is provided in the groove 521b. When the second dust accessory 50 is installed to the preset circumferential position, the lighting element 65 is at least partially embedded in the groove 521b to be close to the light incident surface 521a.

Specifically, the lighting element 65 is an LED lamp bead, the LED lamp bead has an arc-shaped light emitting surface, and the light incident surface 521a is also an arc-shaped surface. In this way, when the lighting element 65 is partially embedded in the groove 521b, the arc-shaped light emitting surface and the arc-shaped light incident surface 521a can be arranged relative to each other, which can reduce light scattering and improve the lighting effect.

In this example, the electric tool is the above-mentioned vacuum cleaner 100. In other examples, the electric tool may also be a handheld electric tool, such as a drill tool, a saw tool, or a long-pole tool. The electric tool may also be a hand-pushed electric tool, such as a hand-pushed lawn mower. The electric tool may also be a bench tool, such as a bench saw. For example, the electric tool is the bench tool, which includes a tool body and a tool accessory mounted to the tool body, the tool accessory may be a saw blade, a remote controller is mounted on the tool body, and a light guide member may be mounted on the tool body. When the remote controller is mounted close to the light guide member, a lighting element on the remote controller can emit light that enters the light guide member.
