[0042] Figure 1 A spray fan 100 is shown for spraying water mist, and the water mist diffuses into the air, capable of cooling the environment. The spray fan 100 can be applicable to outdoor places, such as basketball courts, parks, playgrounds, etc. When the spray fan 100 is used outdoors, the spray fan 100 can use the water in a bucket. The spray fan 100 can also be applicable to indoor places, such as shopping malls, factories, warehouses, etc. When the spray fan 100 is used indoors, the spray fan 100 can be connected to a water pipe. To illustrate the technical solution of this application, the front side, rear side, left side, right side, upper side, and lower side are also defined as Figure 1 shown.

[0043] As Figure 1 and Figure 2 shown, the spray fan 100 includes: a fan assembly 200, a nozzle 300, a support assembly 400, and a power supply assembly 500. Among them, the fan assembly 200 includes fan blades 210 and a first motor 220 that drives the fan blades 210 to rotate. The nozzle 300 is disposed on the fan assembly 200, specifically disposed on the front surface of the spray fan 100 (i.e., the front side of the spray fan 100), for spraying water mist outward. Optionally, the number of nozzles 300 is greater than or equal to 1, and the nozzle 300 can be as Figure 1 and Figure 2The above-described settings are on both sides of the front of the spray fan 100, and can also be set at other positions, which is not limited in this application. The support assembly 400 is used to support the fan assembly 200. The support assembly 400 includes a part disposed below the fan assembly 200 and parts connected to the left and right sides of the fan assembly 200. The power supply assembly 500 is used to supply power to the first 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 a battery pack interface configured to be electrically connected to the battery pack 530, and the second power interface 520 is a Type-C interface configured to be electrically connected to an external power supply 540. Among them, when the battery pack 530 is combined with the first power interface 510 (battery pack interface), at least part of the battery pack 530 is exposed outside the housing 410 of the support assembly 400.

[0044] In some embodiments, the power supply assembly 500 is disposed on the support assembly 400. As Figure 3 and Figure 4 shown, the first power interface 510 is disposed in the insertion space of the battery pack 530. The insertion direction of the battery pack 530 into the spray fan 100 is substantially the same as the spraying direction of the nozzle 300, that is, it is inserted from the rear side of the spray fan 100 to the front side of the spray fan 100. Optionally, the angle A between the first power interface 510 and the horizontal plane extending in the front-rear direction of the spray fan 100 is greater than or equal to 0 degree and less than or equal to 30 degrees. Optionally, the angle A between the first power interface 510 and the horizontal plane extending in the front-rear direction of the spray fan 100 can be 10 degrees. Optionally, the angle A between the first power interface 510 and the horizontal plane extending in the front-rear direction of the spray fan 100 can be 15 degrees. Optionally, the angle A between the first power interface 510 and the horizontal plane extending in the front-rear direction of the spray fan 100 can be 23 degrees.

[0045] In some embodiments, the angle between the first power interface 510 and the vertical plane extending in the front-rear direction of the spray fan 100 is greater than or equal to 0 degrees and less than or equal to 30 degrees. Among them, the angle between the first power interface 510 and the vertical plane extending in the front-rear direction of the spray fan 100 includes the angle formed by the left side of the first power interface 510 and the vertical plane extending in the front-rear direction of the spray fan 100, or the angle formed by the right side of the first power interface 510 and the vertical plane extending in the front-rear direction of the spray fan 100. Optionally, the angle between the first power interface 510 and the vertical plane extending in the front-rear direction of the spray fan 100 can be 10 degrees. Optionally, the angle between the first power interface 510 and the vertical plane extending in the front-rear direction of the spray fan 100 can be 18 degrees. Optionally, the angle between the first power interface 510 and the vertical plane extending in the front-rear direction of the spray fan 100 can be 28 degrees.

[0046] As Figure 4 shown, the second power interface 520 is provided on the housing 410 of the support assembly 400 of the spray fan 100, specifically on the back of the spray fan 100 (i.e., the rear side of the spray fan 100), opposite to the position where the nozzle 300 is provided, avoiding the water mist ejected outward by the nozzle 300 from splashing inside the second power interface 520. Optionally, there is a matching waterproof protection member 521 for the second power interface 520. When the second power interface 520 is not in use, the waterproof protection member 521 is installed on the second power interface 520, further avoiding the water mist ejected outward by the nozzle 300 from splashing on the second power interface 520. Optionally, the angle between the extension direction of the second power interface 520 and the horizontal plane extending in the front-rear direction in the spray fan 100 is greater than or equal to 0 degrees and less than or equal to 30 degrees. Among them, the extension direction of the second power interface 520 specifically refers to the direction formed by the connection line between the foremost end 5201 and the 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 in the front-rear direction in the spray fan 100 can be 15 degrees. Optionally, the angle between the extension direction of the second power interface 520 and the horizontal plane extending in the front-rear direction in the spray fan 100 can be 25 degrees. Optionally, the angle between the extension direction of the second power interface 520 and the horizontal plane can be as Figure 4 shown as 0 degrees, that is, the extension direction of the second power interface 520 is parallel to the horizontal plane extending in the front-rear direction in the spray fan 100, making it more convenient for the user to use the second power interface 520 when using the spray fan 100. Optionally, the angle between the extension direction of the second power interface 520 and the horizontal plane can be as Figure 5 shown as 30 degrees.

[0047] In some embodiments, the angle between the second power interface 520 and the vertical plane extending in the front-rear direction in the spray fan 100 is greater than or equal to 0 degrees and less than or equal to 90 degrees. Wherein, the angle between the second power interface 520 and the vertical plane extending in the front-rear direction in the spray fan 100 includes the angle formed by the second power interface 520 and the left side of the vertical plane extending in the front-rear direction in the spray fan 100, or the angle formed by the second power interface 520 and the right side of the vertical plane extending in the front-rear direction in the spray fan 100. Optionally, the angle between the second power interface 520 and the vertical plane extending in the front-rear direction in the spray fan 100 is 5 degrees. Optionally, the angle between the second power interface 520 and the vertical plane extending in the front-rear direction in the spray fan 100 is 30 degrees. Optionally, the angle between the second power interface 520 and the vertical plane extending in the front-rear direction in the spray fan 100 is 55 degrees. Optionally, the angle between the second power interface 520 and the vertical plane extending in the front-rear direction in the spray fan 100 is 83 degrees.

[0048] In some embodiments, as Figure 6 and Figure 7 shown, the power supply assembly 500 further includes a charging circuit 550, the spray fan 100 further includes a control main board 600 and a main control module 610. The control main board 600 is disposed inside the housing 410 of the support assembly 400, specifically inside the front side of the housing 410. The main control module 610 is used to control the charging mode of the spray fan 100. Wherein, the main control module 610 is powered by the power supply assembly 500, and the main control module 610 can be disposed on the control main board 600.

[0049] In some embodiments, the second power interface 520 is a direct current interface, and the external power supply 540 is direct current. Then at this time, the external power supply 540 can be a battery pack. The battery pack can be composed of a group of battery units. For example, the battery units can be connected in series into a single power branch to form a 1P battery pack. In addition, the external power supply 540 can also be direct current provided in other forms. In some embodiments, the second power interface 520 is an alternating current interface, and the external power supply 540 is alternating current, that is, 120V or 220V alternating current mains can be connected through the second power interface 520. Then at this time, the power supply assembly 500 further includes an AC-DC conversion circuit to convert the external power supply 540 into direct current. For 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, both can be converted into direct current of the voltage required by the spray fan 100 through the DC-DC conversion circuit in the power supply assembly 500. Similarly, the direct current of the battery pack 530 can also be converted into direct current of the voltage required by the spray fan 100 through the DC-DC conversion circuit.

[0050] Optionally, as Figure 6As shown, the charging circuit 550 includes an AC-DC module 551 (i.e., an AC-DC conversion circuit) and a DC-DC module 552 (i.e., a DC-DC conversion circuit). Among them, the AC-DC module 551 is used to convert alternating current into direct current when the external power supply 540 is alternating current. The DC-DC module 552 is used to change the voltage of the direct current converted when the external power supply 540 is alternating current, or to change the voltage of the direct current when the external power supply 540 itself is direct current, and output a supply voltage suitable for the first motor 220, the battery pack 530, etc. to supply power to them. At the same time, the DC-DC module 552 can also change the voltage of the direct current output by the battery pack 530 and output a supply voltage suitable for the first motor 220, etc. to supply power to it.

[0051] Optionally, as Figure 6 shown, a bi-directional conversion circuit exists between the external power supply 540, the AC-DC module 551, the DC-DC module 552, and the battery pack 530. That is, the direct current output by the battery pack 530 can first pass through the DC-DC module 552 and then be converted into alternating current by the AC-DC module 551 for external power output.

[0052] When the charging condition is met, the main control module 610 controls the charging circuit 550 to use the external power supply 540 to charge the battery pack 530. At the same time, the main control module 610 controls the external power supply 540 to supply power to the spray fan 100. At this time, the second power interface 520 needs to be electrically connected to the external power supply 540, and the first power interface 510 is electrically connected to the battery pack 530. Among them, the charging condition is that the input power of the external power supply 540 is greater than the power consumption of the spray fan 100, that is, the input power of the Type C interface is greater than the power consumption of the spray fan 100. Charge the battery pack 530 through the Type C interface. At this time, the input power of the external power supply 540 is relatively large, which can not only supply power to the spray fan 100 but also charge the battery pack 530. Thus, the battery pack 530 can be charged by the external power supply 540, reducing the situation where the battery pack 530 has insufficient power and cannot supply power to the spray fan 100. And even when the battery pack 530 has insufficient power, it can directly use the external power supply 540 for charging without replacing the battery pack 530, making the spray fan 100 have better endurance.

[0053] In some embodiments, 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 operating power required by the spray fan 100 (i.e., the input power of the Type-C interface is less than the operating power of the spray fan 100), the main control module 610 controls the battery pack 530 and the external power supply 540 to supply power to the spray fan 100 together. At this time, the input power of the external power supply 540 is relatively small. To avoid the unsatisfactory working effect of the spray fan 100 when relying solely on the external power supply 540 to supply power to the spray fan 100, the battery pack 530 and the external power supply 540 are used together to supply power to the spray fan 100.

[0054] In some embodiments, 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 operating power of the spray 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 spray fan 100 at this time.

[0055] In some embodiments, 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 connected to the second electrical device, the main control module 610 controls the battery pack 530 to supply power to the second electrical device. Among them, the second electrical device is any electrical device other than the spray fan 100, and the present application does not make any limitations.

[0056] By setting the second power interface 520 as a bidirectional Type-C interface, when the second power interface 520 is connected to the external power supply 540, it can charge the battery pack 530 or supply power to the spray fan 100. When the second power interface 520 is connected to the second electrical device, the battery pack 530 can supply power to the second electrical device. Thus, the spray fan 100 can also act as a power supply device in addition to being an electrical device.

[0057] In some embodiments, the spray fan 100 further includes a wireless communication module 620, and the wireless communication module 620 is used for communication connection with a remote device. Among them, the wireless communication module 620 adopts a Bluetooth or WiFi communication protocol. The remote device can be a mobile phone, a remote control, or any other device with a Bluetooth or WiFi communication protocol that matches the wireless communication module 620. As Figure 7 shown, the wireless communication module 620 is arranged on the control main board 600. Optionally, the wireless communication module 620 has a waterproof structure, so that the wireless communication module 620 can still be used normally after the housing 410 of the support assembly 400 is flooded.

[0058] In some embodiments, the wireless communication module 620 is powered by the power supply component 500. Specifically, the wireless communication module 620 is powered by the external power supply 540 and / or the battery pack 530. Referring to the process of the power supply component 500 powering the spray fan 100, it will not be elaborated here. As Figure 6 shown, the DC-DC module 552 of the charging circuit 550 changes the voltage and outputs a supply voltage suitable for the wireless communication module 620 to power the wireless communication module 620.

[0059] In some embodiments, the remote device can remotely control the startup and / or shutdown of the spray fan 100 based on the wireless communication module 620. Among them, the remote device can directly remotely control the startup and / or shutdown of the spray fan 100 based on the wireless communication module 620, or the remote device can remotely control the timed startup and / or timed shutdown of the spray fan 100 based on the wireless communication module 620. Optionally, the remote device controls the startup and / or shutdown of the spray fan 100 itself based on the wireless communication module 620. Optionally, the remote device controls the opening and / or closing of the water mist sprayed by the nozzle 300 of the spray fan 100 based on the wireless communication module 620. Optionally, the remote device controls the opening and / or closing of the swing function of the spray fan 100 based on the wireless communication module 620.

[0060] In some embodiments, the remote device can remotely control the wind speed of the spray fan 100 based on the wireless communication module 620. Optionally, for example, when the wind speed of the spray fan 100 includes three gears: low wind speed gear, medium wind speed gear, and high wind speed gear, the remote device controls the wind speed of the spray fan 100 to switch step by step between the low wind speed gear, medium wind speed gear, and high wind speed gear based on the wireless communication module 620. Or, the remote device can directly control the wind speed of the spray fan 100 to reach the highest gear (i.e., high wind speed gear) in one key from the lowest gear (i.e., low wind speed gear) based on the wireless communication module 620. Optionally, when the wind speed of the spray fan 100 includes any number of gears, the remote device can control the wind speed switching of the spray fan 100 and the wind speed to reach the highest gear in one key.

[0061] In some embodiments, the remote device can remotely control the amount of water mist sprayed by the nozzle 300 based on the wireless communication module 620. Optionally, for example, the amount of water mist sprayed by the nozzle 300 includes four amounts of water mist, namely the first amount of water mist, the second amount of water mist, the third amount of water mist, and the fourth amount of water mist, and the amount of water mist increases step by step from the first amount of water mist to the fourth amount of water mist. Then the remote device can control the amount of water mist sprayed by the nozzle 300 to switch step by step among these four amounts of water mist, or can also control the nozzle 300 to spray water mist to reach the maximum amount (i.e., the fourth amount of water mist) with one key from the minimum amount (i.e., the first amount of water mist). Optionally, when the amount of water mist sprayed by the nozzle 300 includes any number of amounts of water mist, the remote device can control the switching of the amount of water mist sprayed by the nozzle 300 and the amount of water mist to reach the maximum amount with one key.

[0062] In some embodiments, the remote device can remotely control the swinging angle of the fan assembly 200 based on the wireless communication module 620. Among them, the swinging angle of the fan assembly 200 is the angle at which the fan assembly 200 swings left and right. Among them, the range of the swinging angle of the fan assembly 200 left and right is -90 degrees to 90 degrees, and it is set that the angle of the fan assembly 200 swinging to the left is negative and the angle of swinging to the right is positive. Optionally, the remote device controls the fan assembly 200 to swing 30 degrees to the left (i.e., -30 degrees), that is, the included angle between the fan assembly 200 and the front and back direction of the spray fan 100 is 30 degrees. As Figure 8 shown, it is that the fan assembly 200 swings a certain angle to the left. Optionally, the remote device controls the fan assembly 200 to swing 60 degrees to the right, that is, the included angle between the fan assembly 200 and the front and back direction of the spray fan is 60 degrees. In addition, the remote device can also control the fan assembly 200 to swing at any angle within the range of the swinging angle left and right, which is not limited in this application.

[0063] In some embodiments, based on the wireless communication module 620, the remaining working duration of the spray fan 100 can be displayed on the remote device. Among them, when the spray fan 100 is powered separately by the battery pack 530, the remaining working duration of the spray fan 100 can be displayed according to the remaining power of the battery pack 530, and at the same time, the remaining power of the battery pack 530 can also be displayed on the remote device.

[0064] In some embodiments, based on the wireless communication module 620, the power supply state of the spray fan 100 can be displayed on the remote device. Specifically, it can be displayed that the spray fan 100 is powered by the external power supply 540 and the battery pack 530 is being charged; or it can be displayed that the spray fan 100 is powered by the battery pack 530; or it can be displayed that the spray fan 100 is powered by both the external power supply 540 and the battery pack 530.

[0065] In some embodiments, such as Figure 7As shown, the support assembly 400 includes a housing 410, and the housing 410 forms a coupling portion 411 and a receiving portion 412. The coupling portion 411 is used for detachably coupling the battery pack 530, and an insertion space for the battery pack 530 is formed in the coupling portion 411. When the battery pack 530 is coupled to the coupling portion 411, at least a part of the battery pack 530 is exposed from the housing 410. The receiving portion 412 is used for receiving the second motor 230 and the third motor 240. Among them, the second motor 230 is used to drive the fan assembly 200 to swing, and the third motor 240 is used to drive the water pump so that the water pump provides water source for the nozzle 300.

[0066] In some embodiments, both the second motor 230 and the third motor 240 are powered by the power supply assembly 500. Specifically, the second motor 230 and the third motor 240 are powered by the external power supply 540 and / or the battery pack 530. Referring to the process of the power supply assembly 500 supplying power to the spray fan 100 above, it will not be elaborated here. As Figure 6 shown, the DC-DC module 552 of the charging circuit 550 changes the voltage and outputs a supply voltage suitable for the second motor 230 and the third motor 240 to supply power to the second motor 230 and the third motor 240.

[0067] In some embodiments, as Figure 7 shown, in the vertical direction of the spray fan 100, the second motor 230 is disposed at a position between the coupling portion 411 and the fan assembly 200. Specifically, it is disposed above the coupling portion 411 and below the fan assembly 200. Thus, when the second motor 230 operates, it can control the left and right swing of the support portion 400 connected to the fan assembly 200, and further control the left and right swing of the fan assembly 200.

[0068] In some embodiments, the third motor 240 is disposed in the receiving portion 412 around the coupling portion 411. Specifically, the third motor 240 is disposed around the coupling portion 411 at any position on the front, left side and right side of the coupling portion 411. Optionally, the third motor 240 can be disposed as Figure 9 shown, directly in front of the coupling portion 411. Optionally, the third motor 240 can be disposed at the front side of the coupling portion 411. Optionally, the third motor 240 can be disposed at any position on the left side of the coupling portion 411. Optionally, the third motor 240 can be disposed at any position on the right side of the coupling portion 411.

[0069] In some embodiments, the coupling portion 411 is a recess formed in the housing 410 and opening towards the environment. As Figure 10As shown, the recess extends in the first direction X and is configured to receive at least a portion of the battery pack 530 in parallel with the first direction X. Optionally, the first direction X is substantially parallel to the spraying direction of the nozzle 300 for spraying water mist. The opening direction of the joint portion 411 is substantially opposite to the spraying direction of the nozzle 300, that is, the opening of the recess faces substantially opposite to the direction of the nozzle 300. The nozzle 300 sprays towards the front side of the spray fan 100, and the opening direction of the joint portion 411 is the rear side of the spray fan 100. Thus, when the battery pack 530 is installed in the joint portion 411, it can be avoided that the battery pack 530 is splashed by the water mist sprayed by the nozzle 300, ensuring the safety of the battery pack 530. In addition, the joint portion 411 is provided as a recess opening towards the environment, and the joint portion 411 is not closed relative to the rear end of the spray fan 100, that is, the joint portion 411 is closed on three sides relative to the left side, the front side and the right side of the spray fan 100, making the joint portion 411 semi-open. When the battery pack 530 fails, it is convenient to replace the battery pack 530 at any time. At the same time, setting the joint portion 411 as semi-open saves more cost, reduces the overall weight of the spray fan 100, and makes the volume of the spray fan 100 smaller and the structure more compact when the battery pack 530 is not installed, facilitating storage and carrying.

[0070] Optionally, the recess formed by the joint portion 411 is provided with a first set of electrical contact elements, and the battery pack 530 is provided with a second set of electrical contact elements 531. The first set of electrical contact elements and the second set of electrical contact elements 531 form an electrical connection when at least a portion of the battery pack 530 is inserted into the recess of the joint portion 411, so that the battery pack 530 supplies power to at least the first motor 220. In addition, the battery pack 530 can also supply power to the second motor 230 and the third motor 240. Among them, the first set of electrical contact elements provided in the recess is the first power interface 510, and the second set of electrical contact elements 531 can be the insertion interface of the battery pack 530.

[0071] Optionally, as Figure 11 shown, the width W of the recess of the joint portion 411 in the left-right direction is greater than the height H in the up-down direction, that is, the battery pack 530 is inserted horizontally into the recess formed by the joint portion 411. Thus, in the up-down direction of the spray fan 100, the height of the battery pack 530 is relatively short, making the overall height of the spray fan 100 relatively short, avoiding the problem that the height of the spray fan 100 is relatively high and the volume of the spray fan 100 becomes large and difficult to store and carry when the battery pack 530 is inserted vertically. At the same time, inserting the battery pack 530 horizontally also makes the center of gravity of the spray fan 100 more stable.

[0072] In some embodiments, the housing 410 is provided with an operation panel 700, which is used for the user to manually operate and control the spray fan 100. Optionally, a micro-pressure sensor is installed inside the operation panel 700 to sense the pressing operation of the user based on the micro-pressure sensor. As Figure 8 shown, the operation panel 700 is installed on the front side of the spray fan 100, facilitating the user to adjust the wind speed of the spray fan 100 at any time when using the spray fan 100. Optionally, the operation panel 700 is composed of a waterproof structure, so that even when the water mist sprayed by the nozzle 300 falls on the operation panel 700, it will not affect the operation panel 700, and the operation panel 700 can still be used normally.

[0073] In some embodiments, as Figure 7 shown, the angle B formed by the operation panel 700 and the horizontal plane extending in the front-back direction of the spray fan 100 is greater than or equal to 30 degrees and less than or equal to 50 degrees, facilitating the user to clearly see the operation panel 700 when using the spray fan 100, and enabling the user to conveniently press the buttons at any time during operation. Optionally, the angle B formed by the operation panel 700 and the horizontal plane extending in the front-back direction of the spray fan 100 is 35 degrees. Optionally, the angle B formed by the operation panel 700 and the horizontal plane extending in the front-back direction of the spray fan 100 is 40 degrees. Optionally, the angle B formed by the operation panel 700 and the horizontal plane extending in the front-back direction of the spray fan 100 is 47 degrees.

[0074] In some embodiments, the operation panel 700 includes a power-on and power-off button 710 for controlling the power-on and power-off of the spray fan 100. The operation panel 700 includes a button for turning on and off the swinging function of the spray fan 100 to control the left-right swinging of the spray fan 100. The operation panel 700 includes a button for turning on and off the spraying of the water mist by the nozzle 300 of the spray fan 100 to control whether the nozzle 300 sprays water mist outward.

[0075] In some embodiments, the operation panel 700 includes a wind speed adjustment button. After the spray fan 100 is in the power-on state, the wind speed of the spray fan 100 is adjusted step by step through the wind speed adjustment button. Optionally, the wind speed adjustment button can be a single button, and the wind speed is adjusted by pressing the wind speed adjustment button multiple times. Optionally, the wind speed adjustment button can be multiple buttons, and the user can directly press the button corresponding to the required wind speed according to the demand to adjust the wind speed. The operation panel 700 also includes a one-key maximum wind speed adjustment button. After the spray fan 100 is in the power-on state, the spray fan directly operates at the maximum wind speed through the one-key maximum wind speed adjustment button.

[0076] In some embodiments, the operation panel 700 includes a key for adjusting the water mist amount ejected by the nozzle 300. After the nozzle 300 starts ejecting water mist, the amount of water mist ejected by the nozzle 300 is adjusted step by step through the water mist amount key. Optionally, the water mist amount adjustment key can be a single key, and the water mist amount is adjusted by pressing the water mist amount key multiple times. Optionally, the water mist amount adjustment key can be multiple keys, and the user can directly press the key corresponding to the required water mist amount according to the demand to adjust the water mist amount. The operation panel 700 also includes a key for adjusting the maximum water mist amount with one key. After the nozzle 300 starts ejecting water mist, the nozzle 300 ejects water mist outward at the maximum water mist amount through the maximum water mist amount key with one key.

[0077] In some embodiments, the operation panel 700 includes a key for adjusting the swing angle of the fan assembly 200, specifically, a key for adjusting the left-right swing angle of the fan assembly 200. After the head-shaking function of the spray fan 100 is turned on, the left-right swing angle of the fan assembly 200 is adjusted by pressing the swing angle key of the fan assembly 200. Among them, the left-right swing angle range of the fan assembly 200 is -90 degrees to 90 degrees. It is set that the angle of the fan assembly 200 swinging to the left is negative, and the angle of swinging to the right is positive.

[0078] Optionally, the swing angle key of the fan assembly 200 is a single key. After pressing this key, the fan assembly 200 swings to the left at a preset angle first. Subsequently, after the swing angle of the fan assembly 200 to the left reaches 90 degrees (i.e., the swing angle of the fan assembly 200 is -90 degrees), pressing this key again, the fan assembly 200 continues to swing to the right at a preset angle. Optionally, the swing angle key of the fan assembly 200 is two keys, including a left swing key and a right swing key, corresponding to swinging to the left and swinging to the right respectively. When the user needs the fan assembly 200 to swing to the left, press the left swing key, and then the fan assembly 200 swings to the left at a preset angle. If the user needs the fan assembly 200 to continue swinging to the left, press the left swing key multiple times again. Similarly, when the user needs the fan assembly 200 to swing to the right, press the right swing key, and the fan assembly 200 swings to the right at a preset angle. If the user needs the fan assembly 200 to continue swinging to the right, press the right swing key multiple times again. Optionally, the preset angle can be 5 degrees. Optionally, the preset angle can be 10 degrees. Optionally, the preset angle can be 15 degrees. Optionally, the preset angle can be 30 degrees. Optionally, the preset angle can be any degree between 0 degrees and 90 degrees, which is not limited in this application.

[0079] In some embodiments, the operation panel 700 includes an indicator light 720 for displaying the remaining working duration of the spray fan 100. The number of indicator lights 720 can be 1, or can be other numbers greater than 1 such as 2, 3, 4, 6, etc., and the present application does not make a limitation.

[0080] Optionally, when the number of indicator lights 720 is 1: When the battery power of the spray fan 100 is fully charged at 100%, that is, when the remaining working duration of the spray fan 100 is the longest, the indicator light 720 can be indicated as green. When the battery power of the spray fan 100 reaches the first preset power level, that is, when the remaining working duration of the spray fan 100 is relatively long, the indicator light 720 can be indicated as yellow. When the battery power of the spray fan 100 reaches the second preset power level, that is, when the remaining working duration of the spray fan 100 is relatively short and the spray fan 100 is difficult to maintain long-term operation, the indicator light 720 can be indicated as red to remind the user that the spray fan 100 urgently needs to be charged. Among them, the second preset power level is less than the first preset power level. When the spray fan 100 is completely out of power, the indicator light 720 no longer indicates any color and the indicator light 720 goes out.

[0081] Optionally, when the number of indicator lights 720 is greater than 1, taking the number of indicator lights 720 being 3 as an example for illustration: When all 3 indicator lights 720 are on, it represents that the battery power of the spray fan 100 is fully charged at 100%; when 2 indicator lights 720 are on, it represents that the battery power of the spray fan 100 is greater than or equal to the first preset power level; when only 1 indicator light is on, it represents that the battery power of the spray fan 100 is greater than or equal to the second preset power level; when the indicator lights 720 are all off, it represents that the spray fan 100 is completely out of power. Among them, the number of indicator lights 720 can also be other numbers greater than 1 such as 2, 4, 6, etc., and the present application does not make a limitation.

[0082] In some embodiments, the operation panel 700 can also display the power supply status of the spray fan 100. Specifically, it can display that the spray fan 100 is powered by the external power supply 540 and the battery pack 530 is being charged; or it can display that the spray fan 100 is powered by the battery pack 530; or it can display that the spray fan 100 is powered by both the external power supply 540 and the battery pack 530.

[0083] In some embodiments, the support assembly 400 includes parts arranged on the left and right sides of the fan assembly 200 and connected to the fan assembly 200. Pitching clamping parts are arranged at the connections between the support assembly 400 and the left and right sides of the fan assembly 200, so that when the user adjusts the up-and-down swing angle of the fan assembly 200, it can be clamped at the corresponding position based on the pitching clamping parts. Thus, the user can not only adjust the left-and-right swing angle of the fan assembly 200 according to needs, but also adjust the up-and-down swing angle of the fan assembly 200 according to needs, which better meets the user's usage requirements.

[0084] In some embodiments, the housing 410 is formed with a groove 413 for receiving a water pipe. As Figure 10 shown, a groove 413 is formed at the bottom of the housing 410, and the water pipe can be folded and received in the groove 413. When the user needs to use the spray fan 100, the water pipe can be externally connected to a water source to implement the spray function. For example, the water pipe is externally connected to a water outlet such as a faucet, and water is supplied to the spray fan 100 through the faucet. In some embodiments, the groove 413 can also be an external component fixed to the bottom of the housing 410. Optionally, as Figure 13 shown, the groove 413 can be formed by a plurality of card slots fixed to the bottom of the housing 410.

[0085] As Figure 12 shown, the spray fan 100 can also be placed above a water bucket, the water pipe is externally connected to the water bucket, and the water in the water bucket is sucked through the water pipe to implement the spray function. Optionally, a clamping member cooperating with the water bucket can be provided on the base of the spray fan 100 for clamping the water bucket on the spray fan 100. A handle 110 is provided at the top of the spray fan 100. When the spray fan 100 is lifted by the handle 110, the water bucket can be lifted together, avoiding the need to separately lift the spray fan 100 and the water bucket, making it more convenient to use the spray fan 100.

[0086] As Figure 13 shown, the spray fan 100 further includes a water interface 800, and the water interface 800 can cooperate with an interface groove 414 formed at the bottom of the housing 410. Optionally, the interface groove 414 is a spiral groove, and the outer part 810 of the water interface 800 cooperating with the interface groove is a spiral structure. Thus, by rotating the water interface 800, the water interface 800 can be fixed inside the interface groove 414, and the water interface 800 is fixed to the bottom of the housing 410. In addition, rotating the water interface 800 can also remove the water interface 800 from the bottom of the housing 410, facilitating replacement when the water interface 800 is damaged or blocked. Optionally, the inner part 820 of the water interface 800 also includes a spiral structure. When using an external water pipe, the water interface 800 can better fix and hold the external water pipe, preventing the external water pipe from easily falling off at the interface. In this application, the interface groove 414 is provided at the bottom of the housing 410, so that the water interface 800 can be received and fixed at the bottom of the housing 410, enabling direct connection and use when an external water pipe is needed, which is convenient and fast.

[0087] The foregoing has shown and described the basic principles, main features, and advantages of the present application. Those skilled in the art should understand that the above embodiments do not limit the present application in any form. Any technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present application.
