RELATED APPLICATION INFORMATION

This application claims the benefit under 35 U.S.C. § 119(a) of Chinese Patent Application No. 202410345863.6, filed on Mar. 25, 2024, Chinese Patent Application No. 202421897374.3, filed on Aug. 6, 2024, Chinese Patent Application No. 202421902511.8, filed on Aug. 6, 2024, and Chinese Patent Application No. 202421901469.8, filed on Aug. 6, 2024, which applications are incorporated herein by reference in their entireties.

TECHNICAL FIELD

The present application relates to the field of fan technology and, in particular, to a misting fan.

BACKGROUND

A misting fan includes fan blades and a nozzle. The fan blades are driven by an electric motor to rotate to accelerate air circulation. The nozzle is connected to an external liquid source to perform spraying, thereby achieving cooling, summer relief, air circulation, and a good moisturizing effect. Moreover, a mist is evaporated faster under the action of an airflow and quickly absorbs heat from the surrounding environment, thereby further achieving the purpose of cooling.

The misting fan is generally provided with a power interface mating with a battery pack to power the misting fan. Thus, the misting fan cannot be powered in other manners. If the battery pack has insufficient power, it needs to be replaced with a fully charged battery pack. If the battery pack cannot be replaced, the battery life of the misting fan is difficult to guarantee.

This part provides background information related to the present application, and the background information is not necessarily the existing art.

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.).

FIG. 1 shows a misting fan 100 for spraying a water mist, and the water mist diffuses into the air and can cool the environment. The misting fan 100 can be applied to outdoor places, such as a basketball court, a park, and an amusement park. When the misting fan 100 is used outdoors, the misting fan 100 may use water in a bucket. The misting fan 100 can also be applied to indoor places, such as a shopping mall, a workshop, and a warehouse. When the misting fan 100 is used indoors, the misting fan 100 may be connected to a tap water pipe. To illustrate technical solutions of the present application, a front side, a rear side, a left side, a right side, an upper side, and a lower side shown in FIG. 1 are defined.

As shown in FIGS. 1 and 2, the misting fan 100 includes a fan assembly 200, a nozzle 300, a support assembly 400, and a power supply assembly 500. The fan assembly 200 includes fan blades 210 and a first electric motor 220 for driving the fan blades 210 to rotate. The nozzle 300 is disposed on the fan assembly 200 and specifically on a front surface of the misting fan 100 (that is, the front side of the misting fan 100) and configured to spray a water mist outward. Optionally, the number of nozzles 300 is greater than or equal to 1. Nozzles 300 may be disposed on two sides of the front surface of the misting fan 100, as shown in FIGS. 1 and 2, or may be disposed at other positions, which are not limited in the present application. The support assembly 400 is configured to support the fan assembly 200, and the support assembly 400 includes a portion below the fan assembly 200 and connecting portions on the left and right sides of the fan assembly 200. The power supply assembly 500 is configured to supply power to the first electric motor 220. The power supply assembly 500 includes at least two power interfaces, one of the at least two power interfaces is a Type-C interface, and one of the at least two power interfaces is a battery pack interface. Optionally, the at least two power interfaces included in the power supply assembly 500 include a first power interface 510 and a second power interface 520, the first power interface 510 is the battery pack interface and configured to be electrically connected to a battery pack 530, and the second power interface 520 is the Type-C interface and configured to be electrically connected to an external power supply 540. When the battery pack 530 is coupled to the first power interface 510 (the battery pack interface), at least part of the battery pack 530 is exposed out of a housing 410 of the support assembly 400.

In some examples, the power supply assembly 500 is disposed on the support assembly 400. As shown in FIGS. 3 and 4, the first power interface 510 is disposed in a space for insertion of the battery pack 530, and an insertion direction of the battery pack 530 into the misting fan 100 is substantially the same as a spraying direction of the nozzle 300, that is, the battery pack is inserted from the rear side of the misting fan 100 towards the front side of the misting fan 100. Optionally, the angle A between the first power interface 510 and a horizontal plane extending along a front and rear direction of the misting fan 100 is greater than or equal to 0° and less than or equal to 30°. Optionally, the angle A between the first power interface 510 and the horizontal plane extending along the front and rear direction of the misting fan 100 may be 10°. Optionally, the angle A between the first power interface 510 and the horizontal plane extending along the front and rear direction of the misting fan 100 may be 15°. Optionally, the angle A between the first power interface 510 and the horizontal plane extending along the front and rear direction of the misting fan 100 may be 23°.

In some examples, the angle between the first power interface 510 and a vertical plane extending along the front and rear direction of the misting fan 100 is greater than or equal to 0° and less than or equal to 30°. The angle between the first power interface 510 and the vertical plane extending along the front and rear direction of the misting fan 100 includes an angle between the first power interface 510 and the left side of the vertical plane extending along the front and rear direction of the misting fan 100 or an angle between the first power interface 510 and the right side of the vertical plane extending along the front and rear direction of the misting fan 100. Optionally, the angle between the first power interface 510 and the vertical plane extending along the front and rear direction of the misting fan 100 may be 10°.

Optionally, the angle between the first power interface 510 and the vertical plane extending along the front and rear direction of the misting fan 100 may be 28°.

As shown in FIG. 4, the second power interface 520 is disposed on the housing 410 of the support assembly 400 of the misting fan 100 and specifically on a rear surface of the misting fan 100 (that is, the rear side of the misting fan 100), and the second power interface faces away from the nozzle 300 in position, preventing the inside of the second power interface 520 from being sprayed by the water mist sprayed by the nozzle 300. Optionally, the second power interface 520 has a matching waterproof protector 521. When the second power interface 520 is not used, the waterproof protector 521 is mounted on the second power interface 520, further preventing the second power interface 520 from being sprayed by the water mist sprayed by the nozzle 300. Optionally, the angle between an extension direction of the second power interface 520 and the horizontal plane extending along the front and rear direction of the misting fan 100 is greater than or equal to 0° and less than or equal to 30°. The extension direction of the second power interface 520 specifically refers to a direction formed by a line between a foremost end 5201 and a rearmost end 5202 of the second power interface 520. Optionally, the angle between the extension direction of the second power interface 520 and the horizontal plane extending along the front and rear direction of the misting fan 100 may be 15°. Optionally, the angle between the extension direction of the second power interface 520 and the horizontal plane extending along the front and rear direction of the misting fan 100 may be 25°. Optionally, the angle between the extension direction of the second power interface 520 and the horizontal plane extending along the front and rear direction of the misting fan 100 may be 0°, as shown in FIG. 4, that is, the extension direction of the second power interface 520 is parallel to the horizontal plane extending along the front and rear direction of the misting fan 100, so that a user can more conveniently use the second power interface 520 when using the misting fan 100. Optionally, the angle between the extension direction of the second power interface 520 and the horizontal plane may be 30°, as shown in FIG. 5.

In some examples, the angle between the second power interface 520 and the vertical plane extending along the front and rear direction of the misting fan 100 is greater than or equal to 0° and less than or equal to 90°. The angle between the second power interface 520 and the vertical plane extending along the front and rear direction of the misting fan 100 includes an angle between the second power interface 520 and the left side of the vertical plane extending along the front and rear direction of the misting fan 100 or an angle between the second power interface 520 and the right side of the vertical plane extending along the front and rear direction of the misting fan 100. Optionally, the angle between the second power interface 520 and the vertical plane extending along the front and rear direction of the misting fan 100 is 5°.

Optionally, the angle between the second power interface 520 and the vertical plane extending along the front and rear direction of the misting fan 100 is 83°.

In some examples, as shown in FIGS. 6 and 8, the power supply assembly 500 further includes a charging circuit 550, the misting fan 100 further includes a control motherboard 600 and a main control module 610, the control motherboard 600 is disposed inside the housing 410 of the support assembly 400 and specifically inside the front side of the housing 410, and the main control module 610 is configured to control a charging manner of the misting fan 100. The main control module 610 is powered by the power supply assembly 500, and the main control module 610 may be disposed on the control motherboard 600.

In some examples, the second power interface 520 is a direct current interface, and the external power supply 540 provides a direct current. In this case, the external power supply 540 may be a battery pack, and the battery pack may be composed of a group of battery units. For example, the battery units may be connected in series into a single power supply branch to form a 1P battery pack. Additionally, the external power supply 540 may be another form of direct current. In some examples, the second power interface 520 is an alternating current interface, and the external power supply 540 provides an alternating current, that is, 120 V or 220 V alternating current mains power may be connected through the second power interface 520. In this case, the power supply assembly 500 further includes an alternating current-direct current conversion circuit to convert the external power supply 540 into a direct current. The direct current provided by the external power supply 540 or the direct current converted from the alternating current of the external power supply 540 may be converted by a direct current-direct current conversion circuit in the power supply assembly 500 into a direct current with a voltage required by the misting fan 100. Similarly, a direct current of the battery pack 530 may be converted by the direct current-direct current conversion circuit into the direct current with the voltage required by the misting fan 100.

Optionally, as shown in FIG. 6, the charging circuit 550 includes an AC-DC module 551 (that is, the alternating current-direct current conversion circuit) and a DC-DC module 552 (that is, the direct current-direct current conversion circuit). The AC-DC module 551 is configured to convert the alternating current into the direct current when the external power supply 540 provides the alternating current. The DC-DC module 552 is configured to change a voltage of the direct current converted from the alternating current of the external power supply 540 or to change a voltage of the direct current of the external power supply 540 itself and output a power supply voltage suitable for the first electric motor 220, the battery pack 530, and so on to supply power to the first electric motor 220, the battery pack 530, and so on. Meanwhile, the DC-DC module 552 may also change a voltage of the direct current output from the battery pack 530 and output the power supply voltage suitable for the first electric motor 220 and so on to supply power to the first electric motor 220 and so on.

Optionally, as shown in FIG. 6, circuits between the external power supply 540, the AC-DC module 551, the DC-DC module 552, and the battery pack 530 are all bidirectional conversion circuits, that is, the direct current output from the battery pack 530 may pass through the DC-DC module 552 and then be converted by the AC-DC module 551 into an alternating current, so as to output power to the outside.

When the power of the external power supply 540 is greater than a preset power threshold, the external power supply 540 may charge the battery pack 530 and simultaneously supply power to the misting fan 100. When the power of the external power supply 540 is less than the preset power threshold, the external power supply 540 and the battery pack 530 jointly supply power to the misting fan 100. When the power of the external power supply 540 is equal to the preset power threshold, the external power supply 540 supplies power to the misting fan 100. A specific working mode of the external power supply 540 is described below.

When the charging condition is satisfied, the main control module 610 controls the charging circuit 550 to charge the battery pack 530 using the external power supply 540. At the same time, the main control module 610 controls the external power supply 540 to supply power to the misting fan 100. In this case, the second power interface 520 needs to be electrically connected to the external power supply 540, and the first power interface 510 needs to be electrically connected to the battery pack 530. The charging condition is that input power of the external power supply 540 is greater than a required power for use of the misting fan 100, that is, input power of the Type-C interface is greater than the required power for use of the misting fan 100. The battery pack 530 is charged through the Type-C interface. In this case, the external power supply 540 has relatively large input power and can not only supply power to the misting fan 100 but also charge the battery pack 530. Thus, the battery pack 530 can be charged by the external power supply 540, avoiding the case where the battery pack 530 has insufficient power and cannot supply power to the misting fan 100. Even if the battery pack 530 has insufficient power, the external power supply 540 can be directly used for charging without replacing the battery pack 530 so that the misting fan 100 has relatively good endurance.

In some examples, when the second power interface 520 is electrically connected to the external power supply 540, the first power interface 510 is electrically connected to the battery pack 530, and the input power of the external power supply 540 is less than the required power for use of the misting fan 100 (that is, the input power of the Type-C interface is less than the required power for use of the misting fan 100), the main control module 610 controls the battery pack 530 and the external power supply 540 to jointly supply power to the misting fan 100. In this case, the external power supply 540 has relatively small input power. To avoid a poor work effect of the misting fan 100 when only the external power supply 540 supplies power to the misting fan 100, the battery pack 530 and the external power supply 540 are used to jointly supply power to the misting fan 100.

In some examples, when the second power interface 520 is electrically connected to the external power supply 540 and the input power of the external power supply 540 is equal to the required power for use of the misting fan 100, or when the second power interface 520 is electrically connected to the external power supply 540 and the first power interface 510 is not electrically connected to the battery pack 530, the main control module 610 controls only the external power supply 540 to supply power to the misting fan 100.

In some examples, the second power interface 520 is a bidirectional Type-C interface. When the first power interface 510 is electrically connected to the battery pack 530 and the second power interface 520 is electrically connected to a second powered device (that is, an external powered device), the main control module 610 controls the battery pack 530 to supply power to the second powered device. The second powered device is any powered device other than the misting fan 100, which is not limited in the present application. The second powered device may be a power tool, a household appliance, or a personal powered device, such as an electric drill 100a, a chainsaw 100b, a string trimmer 100c, a blower 100d, a power bank 100e, a notebook 100f, or a smartphone 100g, as shown in FIG. 7.

The second power interface 520 is configured to be the bidirectional Type-C interface so that when the second power interface 520 is connected to the external power supply 540, the battery pack 530 can be charged or the misting fan 100 can be powered; and when the second power interface 520 is connected to the second powered device, the battery pack 530 can supply power to the second powered device. Thus, the misting fan 100 can be used as a power supply device in addition to a powered device.

In some examples, the misting fan 100 further includes a wireless communication module 620 communicatively connected to a remote device 621. The wireless communication module 620 is configured to communicate with the remote device 621. The wireless communication module 620 is configured to enable bidirectional communication with the remote device 621 to transmit data information to the remote device 621 and receive input information from the remote device 621. The wireless communication module 620 adopts a Bluetooth or Wi-Fi communication protocol. The remote device 621 may be a mobile phone, a remote control, or any other device with a Bluetooth or Wi-Fi communication protocol matching the wireless communication module 620. The Bluetooth or Wi-Fi communication protocol is used for scanning the remote device 621 surrounding the misting fan 100 and connecting the misting fan 100 to the remote device 621. As shown in FIG. 8, the wireless communication module 620 is disposed on the control motherboard 600. Optionally, the wireless communication module 620 adopts a waterproof structure so that after water enters the housing 410 of the support assembly 400, the wireless communication module 620 can still be used normally.

In some examples, the wireless communication module 620 is powered by the power supply assembly 500. For the specific power supply of the wireless communication module 620 by the external power supply 540 and/or the battery pack 530, reference is made to the preceding process of powering the misting fan 100 by the power supply assembly 500, and the details are not repeated here. As shown in FIG. 6, the DC-DC module 552 in the charging circuit 550 changes the voltage and outputs a power supply voltage suitable for the wireless communication module 620 to supply power to the wireless communication module 620.

In some examples, the wireless communication module 620 is configured to transmit state information about the misting fan 100 to the remote device 621. After being connected to the remote device 621 through the Bluetooth or Wi-Fi communication protocol, the wireless communication module transmits to the remote device 621 information about the misting fan 100 and acquired through the Bluetooth or Wi-Fi communication protocol and transmits other information about the misting fan 100 to an external device. The transmitted information is not limited in the present application. For example, the transmitted information may be a working state of the misting fan, such as whether the misting fan is powered on, whether the misting fan is spraying, and a wind speed. Additionally, the misting fan 100 may receive information from the remote device 621 based on the Bluetooth or Wi-Fi communication protocol. The received information is not limited in the present application. The received information is any information for controlling the operation of the misting fan 100.

In some examples, the remote device 621 may remotely control, based on the wireless communication module 620, the misting fan 100 to be powered on and/or off. The remote device 621 may remotely and directly control, based on the wireless communication module 620, the misting fan 100 to be powered on and/or off. Alternatively, the remote device 621 may remotely control, based on the wireless communication module 620, the misting fan 100 to be powered on and/or off at a scheduled time. For example, the misting fan 100 is remotely controlled by the remote device 621 to be powered on and/or off at a preset time or to be powered on and/or off in a certain time. Optionally, the remote device 621 controls, based on the wireless communication module 620, the misting fan 100 itself to be powered on and/or off. Optionally, the remote device 621 controls, based on the wireless communication module 620, the spraying of the nozzle 300 of the misting fan 100 to be enabled and/or disabled. Optionally, the remote device 621 controls, based on the wireless communication module 620, an oscillation function of the misting fan 100 to be enabled and/or disabled.

In some examples, the remote device 621 may remotely control, based on the wireless communication module 620, the wind speed of the misting fan 100. Optionally, for example, when the wind speed of the misting fan 100 includes three gears: a low wind speed, a medium wind speed, and a high wind speed, the remote device controls, based on the wireless communication module 620, the wind speed of the misting fan 100 to be switched step by step between the low wind speed, the medium wind speed, and the high wind speed. Alternatively, the remote device 621 may directly control, based on the wireless communication module 620, the wind speed of the misting fan 100 to reach the highest gear (that is, the high wind speed) from the lowest gear (that is, the low wind speed) with one push. Optionally, when the wind speed of the misting fan 100 includes any number of gears, the remote device 621 may control the wind speed of the misting fan 100 to be switched or the wind speed to reach the highest gear with one push.

In some examples, the remote device 621 may remotely control, based on the wireless communication module 620, a volume of the water mist sprayed by the nozzle 300. Optionally, for example, the volume of the water mist sprayed by the nozzle 300 includes four water mist volumes: a first water mist volume, a second water mist volume, a third water mist volume, and a fourth water mist volume, which increase step by step from the first water mist volume to the fourth water mist volume. The remote device 621 may control the volume of the water mist sprayed by the nozzle 300 to be switched step by step between the four water mist volumes or may control the water mist sprayed by the nozzle 300 to reach the maximum volume (that is, the fourth water mist volume) from the minimum volume (that is, the first water mist volume) with one push. Optionally, when the volume of the water mist sprayed by the nozzle 300 includes any number of water mist volumes, the remote device 621 may control the volume of the water mist sprayed by the nozzle 300 to be switched or the volume of the water mist to reach the maximum volume with one push.

In some examples, the remote device 621 may remotely control, based on the wireless communication module 620, an angle of oscillation of the fan assembly 200. The angle of oscillation of the fan assembly 200 is an angle of left and right oscillation of the fan assembly 200. The angle of left and right oscillation of the fan assembly 200 ranges from −90° to 90°. It is set that an angle of left oscillation of the fan assembly 200 is negative and an angle of right oscillation of the fan assembly 200 is positive. Optionally, the remote device 621 controls the fan assembly 200 to oscillate left by 30° (that is, −30°), that is, when looking down at the misting fan 100, the fan assembly 200 is rotated 30° counterclockwise. At this time, the angle between a surface where the fan assembly 200 is located and the left and right direction of the misting fan 100 is 30°. As shown in FIG. 9, the fan assembly 200 oscillates left by a certain angle. Optionally, the remote device 621 controls the fan assembly 200 to oscillate right by 60°, that is, when looking down at the misting fan 100, the fan assembly 200 is rotated 30° clockwise. At this time, the angle between the fan assembly 200 is located and the left and right direction of the misting fan is 60°. Additionally, the remote device 621 may control the fan assembly 200 to oscillate by any angle within the range of the angle of left and right oscillation, which is not limited in the present application.

In some examples, the remote device may separately control, based on the wireless communication module 620, the wind speed of the misting fan 100, the volume of the water mist sprayed by the nozzle 300, or the angle of oscillation of the fan assembly 200. After the wind speed of the misting fan 100 is controlled, the volume of the water mist sprayed by the nozzle 300 and/or the angle of oscillation of the fan assembly 200 are controlled. Alternatively, after the volume of the water mist sprayed by the nozzle 300 is controlled, the wind speed of the misting fan 100 and/or the angle of oscillation of the fan assembly 200 may be controlled. Alternatively, after the angle of oscillation of the fan assembly 200 is controlled, the wind speed of the misting fan 100 and/or the volume of the water mist sprayed by the nozzle 300 may be controlled.

In some examples, the remote device may remotely control, with one push and based on the wireless communication module 620, any two or all three of the wind speed of the misting fan 100, the volume of the water mist sprayed by the nozzle 300, and the angle of oscillation of the fan assembly 200. Specific combinations of any two or three of the wind speed, the volume of the water mist sprayed, and the angle of oscillation are not limited in the present application. Optionally, the remote device may remotely control, with one push, the wind speed of the misting fan 100 to be maximum and meanwhile the water mist volume of the nozzle 300 to be maximum. Optionally, the remote device may remotely control, with one push, the wind speed of the misting fan 100 to be maximum and meanwhile the fan assembly 200 to oscillate within −90° to 90°.

In some examples, a remaining working duration of the misting fan 100 may be displayed on the remote device based on the wireless communication module 620. When the misting fan 100 is powered by the battery pack 530 alone, the remaining working duration of the misting fan 100 may be displayed according to remaining power of the battery pack 530, and the remaining power of the battery pack 530 may also be displayed on the remote device.

In some examples, a power supply state of the misting fan 100 may be displayed on the remote device based on the wireless communication module 620. Specifically, it may be displayed that the misting fan 100 is being powered by the external power supply 540 and the battery pack 530 is being charged, that the misting fan 100 is being powered by the battery pack 530, or that the misting fan 100 is being powered jointly by the external power supply 540 and the battery pack 530.

In some examples, as shown in FIG. 8, the support assembly 400 includes the housing 410, and the housing 410 forms a coupling portion 411 and an accommodation portion 412. The coupling portion 411 is used for detachably coupling the battery pack 530, and the coupling portion 411 forms the space for insertion of the battery pack 530. When the battery pack 530 is coupled to the coupling portion 411, at least part of the battery pack 530 is exposed out of the housing 410. The accommodation portion 412 is used for accommodating a third electric motor 230 and a second electric motor 240. The third electric motor 230 is configured to drive the fan assembly 200 to oscillate, and the second electric motor 240 is configured to drive a water pump 241 to supply a water source to the nozzle 300.

In some examples, both the third electric motor 230 and the second electric motor 240 are powered by the power supply assembly 500. For the specific power supply of the third electric motor 230 and the second electric motor 240 by the external power supply 540 and/or the battery pack 530, reference is made to the preceding process of powering the misting fan 100 by the power supply assembly 500, and the details are not repeated here. As shown in FIG. 6, the DC-DC module 552 in the charging circuit 550 changes the voltage and outputs a power supply voltage suitable for the third electric motor 230 and the second electric motor 240 to supply power to the third electric motor 230 and the second electric motor 240.

In some examples, as shown in FIG. 8, the third electric motor 230 is disposed between the coupling portion 411 and the fan assembly 200 along an up and down direction of the misting fan 100. Specifically, the third electric motor 230 is disposed above the coupling portion 411 and below the fan assembly 200. Therefore, the third electric motor 230 in operation may control a support portion 400 connected to the fan assembly 200 to oscillate left and right to control the fan assembly 200 to oscillate left and right.

In some examples, the second electric motor 240 is disposed in the accommodation portion 412 and surrounds the coupling portion 411. Specifically, the second electric motor 240 surrounds the coupling portion 411 and is disposed at any position on the front, left, or right side of the coupling portion 411. Optionally, the second electric motor 240 may be disposed directly in front of the coupling portion 411, as shown in FIG. 10. Optionally, the second electric motor 240 may be disposed in front of a side of the coupling portion 411. Optionally, the second electric motor 240 may be disposed at any position on the left side of the coupling portion 411. Optionally, the second electric motor 240 may be disposed at any position on the right side of the coupling portion 411.

In some examples, the coupling portion 411 is a recess formed by the housing 410 and having an opening facing the environment. As shown in FIG. 11, the recess extends along a first direction X and is configured to receive at least part of the battery pack 530 in a direction parallel to the first direction X. Optionally, the first direction X is substantially parallel to a direction in which the nozzle 300 sprays the water mist. The coupling portion 411 is opened in a direction substantially opposite to the spraying direction of the nozzle 300, that is, an orientation of the opening of the recess is substantially opposite to an orientation of the nozzle 300. The nozzle 300 sprays towards the front side of the misting fan 100, and the coupling portion 411 is opened towards the rear side of the misting fan 100. Thus, when mounted in the coupling portion 411, the battery pack 530 can be prevented from being sprayed by the water mist sprayed by the nozzle 300, ensuring the safety of the battery pack 530. Additionally, the coupling portion 411 is configured to be the recess with the opening facing the environment, and the coupling portion 411 is not closed relative to the rear end of the misting fan 100, that is, the coupling portion 411 is closed relative to the left, front, and right sides of the misting fan 100 so that the coupling portion 411 is semi-open, making it convenient to replace the battery pack 530 at any time when the battery pack 530 fails. Meanwhile, the coupling portion 411 is configured to be semi-open, saving a cost and reducing the overall weight of the misting fan 100. Moreover, when the battery pack 530 is not mounted, the misting fan 100 is smaller in volume and more compact in structure and is convenient to store and carry.

Optionally, the recess formed by the coupling portion 411 is provided with a first set of electrical contact elements, the battery pack 530 is provided with a second set of electrical contact elements 531, and the first set of electrical contact elements and the second set of electrical contact elements 531 form an electrical connection when at least part of the battery pack 530 is inserted into the recess of the coupling portion 411 so that the battery pack 530 supplies power to at least the first electric motor 220. Additionally, the battery pack 530 may supply power to the third electric motor 230 and the second electric motor 240. The first set of electrical contact elements disposed on the recess is the first power interface 510, and the second set of electrical contact elements 531 may be an insertion interface of the battery pack 530.

Optionally, as shown in FIG. 12, the width W of the recess of the coupling portion 411 along a left and right direction is greater than the height H of the recess along the up and down direction, that is, the battery pack 530 is inserted horizontally into the recess formed by the coupling portion 411. Thus, along the up and down direction of the misting fan 100, the height of the battery pack 530 is relatively small so that the overall height of the misting fan 100 is relatively small, avoiding the following problem: the misting fan 100 is relatively high in height and becomes larger in volume and thus is difficult to store and carry when the battery pack 530 is inserted vertically. Meanwhile, the battery pack 530 is inserted in the flat manner so that the misting fan 100 has a more stable center of gravity.

In some examples, the housing 410 is provided with an operation panel 700 for the user to manually operate to control the misting fan 100. Optionally, a micropressure sensor is mounted inside the operation panel 700 to sense a pressing operation of the user. As shown in FIG. 9, the operation panel 700 is mounted on the front side of the misting fan 100 to facilitate operations of the user for adjusting the wind speed of the misting fan 100 and so on at any time during use of the misting fan 100. Optionally, the operation panel 700 includes a waterproof structure so that even if the water mist sprayed by the nozzle 300 falls on the operation panel 700, the operation panel 700 is not affected and can still be used normally.

In some examples, as shown in FIG. 8, the angle B between the operation panel 700 and the horizontal plane extending along the front and rear direction of the misting fan 100 is greater than or equal to 30° and less than or equal to 50° so that the user can clearly see the operation panel 700 during use of the misting fan 100, and the user can conveniently press a button at any time to operate the operation panel 700. Optionally, the angle B between the operation panel 700 and the horizontal plane extending along the front and rear direction of the misting fan 100 is 35°. Optionally, the angle B between the operation panel 700 and the horizontal plane extending along the front and rear direction of the misting fan 100 is 40°. Optionally, the angle B between the operation panel 700 and the horizontal plane extending along the front and rear direction of the misting fan 100 is 47°.

In some examples, the operation panel 700 includes an on-off button 710 for controlling the misting fan 100 to be powered or off. The operation panel 700 includes an enable-disable button for the oscillation function of the misting fan 100, which is configured to control the misting fan 100 to oscillate left and right. The operation panel 700 includes an enable-disable button for the spraying of the nozzle 300 of the misting fan 100, which is configured to control whether the nozzle 300 sprays the water mist outward.

In some examples, the operation panel 700 includes a wind speed adjustment button. After the misting fan 100 is in an on state, the wind speed of the misting fan 100 is adjusted step by step through the wind speed adjustment button. Optionally, one wind speed adjustment button may be provided, and the wind speed adjustment button is pressed multiple times so that the wind speed is adjusted. Optionally, multiple wind speed adjustment buttons may be provided, and the user may directly press a button corresponding to a required wind speed to adjust the wind speed as needed. The operation panel 700 further includes a one-push maximum wind speed adjustment button. After the misting fan 100 is in the on state, the one-push maximum wind speed adjustment button enables the misting fan to directly operate at a maximum wind speed.

In some examples, the operation panel 700 includes an adjustment button for the volume of the water mist sprayed by the nozzle 300. After the spraying of the nozzle 300 is enabled, the volume of the water mist sprayed by the nozzle 300 is adjusted step by step through a water mist volume button. Optionally, one water mist volume adjustment button may be provided, and the water mist volume button is pressed multiple times so that the water mist volume is adjusted. Optionally, multiple water mist volume adjustment buttons may be provided, and the user may directly press a button corresponding to a required water mist volume to adjust the water mist volume as needed. The operation panel 700 further includes a one-push maximum water mist volume adjustment button. After the spraying of the nozzle 300 is enabled, the one-push maximum water mist volume button enables the nozzle 300 to spray the water mist outward at a maximum water mist volume.

In some examples, the operation panel 700 includes a button for adjusting the angle of oscillation of the fan assembly 200, which is specifically a button for adjusting the angle of left and right oscillation of the fan assembly 200. After the oscillation function of the misting fan 100 is enabled, the button for the angle of oscillation of the fan assembly 200 is pressed so that the angle of left and right oscillation of the fan assembly 200 is adjusted. The angle of left and right oscillation of the fan assembly 200 ranges from −90° to 90°. It is set that the angle of left oscillation of the fan assembly 200 is negative and the angle of right oscillation of the fan assembly 200 is positive.

Optionally, one button is provided for the angle of oscillation of the fan assembly 200. After the button is pressed, the fan assembly 200 oscillates left by a preset angle. Then, after the fan assembly 200 oscillates left by 90° (that is, the angle of oscillation of the fan assembly 200 is −90°), the button is pressed again so that the fan assembly 200 continues to oscillate right by a preset angle. Optionally, two buttons are provided for the angle of oscillation of the fan assembly 200 and include a left oscillation button and a right oscillation button, which correspond to left oscillation and right oscillation, respectively. When the user requires the fan assembly 200 to oscillate left, the left oscillation button is pressed and then the fan assembly 200 oscillates left by the preset angle. If the user requires the fan assembly 200 to continue to oscillate left, the left oscillation button is pressed again multiple times. Similarly, when the user requires the fan assembly 200 to oscillate right, the right oscillation button is pressed and then the fan assembly 200 oscillates right by the preset angle. If the user requires the fan assembly 200 to continue to oscillate right, the right oscillation button is pressed again multiple times. Optionally, the preset angle may be 5°. Optionally, the preset angle may be 10°. Optionally, the preset angle may be 15°. Optionally, the preset angle may be 30°. Optionally, the preset angle may be any degree between 0° and 90°, which is not limited in the present application.

In some examples, the operation panel 700 includes an indicator light 720 for displaying the remaining working duration of the misting fan 100. The number of indicator lights 720 may be 1, 2, 3, 4, 6, or any other number greater than 1, which is not limited in the present application.

Optionally, the number of indicator lights 720 may be 1. When the power of the misting fan 100 is sufficient (100%), that is, the remaining working duration of the misting fan 100 is the longest, the indicator light 720 may be green. When the power of the misting fan 100 reaches first preset power, that is, the remaining working duration of the misting fan 100 is relatively long, the indicator light 720 may be yellow. When the power of the misting fan 100 reaches second preset power, that is, the remaining working duration of the misting fan 100 is relatively short and the misting fan 100 is difficult to keep working for a relatively long time, the indicator light 720 may be red to remind the user that the misting fan 100 is in urgent need for being charged. The second preset power is lower than the first preset power. When the misting fan 100 is completely out of power, the indicator light 720 no longer indicates any color and the indicator light 720 is off.

Optionally, the number of indicator lights 720 is greater than 1, for example, the number of indicator lights 720 is 3. When three indicator lights 720 are all on, it indicates that the power of the misting fan 100 is sufficient (100%). When two indicator lights 720 are on, it indicates that the power of the misting fan 100 is greater than or equal to the first preset power. When only one indicator light is on, it indicates that the power of the misting fan 100 is greater than or equal to the second preset power. When the indicator lights 720 are all off, it indicates that the misting fan 100 is completely out of power. The number of indicator lights 720 may be 2, 4, 6, or any other number greater than 1, which is not limited in the present application.

In some examples, the operation panel 700 may also display the power supply state of the misting fan 100. Specifically, it may be displayed that the misting fan 100 is being powered by the external power supply 540 and the battery pack 530 is being charged, that the misting fan 100 is being powered by the battery pack 530, or that the misting fan 100 is being powered jointly by the external power supply 540 and the battery pack 530.

In some examples, the support assembly 400 includes portions disposed on the left and right sides of the fan assembly 200 and connected to the fan assembly 200. Pitch fasteners are disposed at connections between the support assembly 400 and the left and right sides of the fan assembly 200. Thus, when the user adjusts an angle of up and down oscillation of the fan assembly 200, the fan assembly 200 may be clamped at a corresponding position through the pitch fasteners. Therefore, the user can not only adjust the angle of left and right oscillation of the fan assembly 200 as needed but also adjust the angle of up and down oscillation of the fan assembly 200 as needed so that use requirements of the user are better satisfied.

In some examples, the housing 410 forms a groove 413 for storing a water pipe. As shown in FIG. 11, the groove 413 is formed at the bottom of the housing 410, and the water pipe may be folded and stored in the groove 413. When the user needs to use the misting fan 100, the water pipe may be connected to an external water source to implement the spraying function. For example, the water pipe is connected to a water outlet such as a faucet, and the faucet delivers water to the misting fan 100. In some examples, the groove 413 may be an external component fixed to the bottom of the housing 410. Optionally, as shown in FIG. 14, the groove 413 may be formed by multiple snap slots fixed on the bottom of the housing 410.

As shown in FIG. 13, the misting fan 100 may be placed on the bucket, the water pipe is connected to the bucket, and water in the bucket is drawn through the water pipe to implement the spraying function. Optionally, a base of the misting fan 100 may be provided with fasteners mating with the bucket and configured to clamp the bucket to the misting fan 100. A handle 110 is disposed at the top of the misting fan 100. When the misting fan 100 is lifted through the handle 110, the bucket may be lifted together, avoiding a need to separately lift the misting fan 100 and the bucket and making the misting fan 100 more convenient to use.

As shown in FIG. 14, the misting fan 100 further includes a water interface 800, and the water interface 800 may mate with an interface groove 414 formed at the bottom of the housing 410. Optionally, the interface groove 414 is a spiral groove, and an outer portion 810 of the water interface 800 mating with the interface groove has a spiral structure. Thus, the water interface 800 is rotated so that the water interface 800 can be fixed into the interface groove 414. The water interface 800 is fixed to the bottom of the housing 410. Additionally, the water interface 800 is rotated so that the water interface 800 can be removed from the bottom of the housing 410 and can be conveniently replaced when the water interface 800 is damaged or clogged. Optionally, an inner portion 820 of the water interface 800 also includes a spiral structure. When an external water pipe is used, the water interface 800 can relatively well fix and clamp the external water pipe so that the external water pipe is prevented from easily falling off the interface. In the present application, the interface groove 414 is disposed at the bottom of the housing 410 so that the water interface 800 can be stored and fixed at the bottom of the housing 410. Thus, when the external water pipe needs to be used, the external water pipe can be directly connected for use, which is convenient and quick.

The basic principles, main features, and advantages of this application are shown and described above. It is to be understood by those skilled in the art that the aforementioned examples do not limit the present application in any form, and all technical solutions obtained through equivalent substitutions or equivalent transformations fall within the scope of the present application.
