[0032] Before any embodiments of the present application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the foregoing drawings.

[0033] In this application, the terms "comprises," "includes," "has," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of 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 apparatus that includes the element.

[0034] In this application, the term "and / or" describes a relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Additionally, the character " / " in this application generally indicates that the related objects are in an "and / or" relationship.

[0035] In this application, the terms "connect," "combine," "couple," and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation.

[0036] In this application, it will be understood by those skilled in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerance caused by manufacturing, assembly, use, etc. associated with a specific value. Such terms should also be considered to disclose a range defined by the absolute values of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values that do not use relative terms should also be disclosed as specific values with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0037] In this application, it will be understood by those skilled in the art that the function performed by an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts.

[0040] In this application, the terms "device", "module" or "unit" can be implemented in the form of hardware or software to achieve specific functions.

[0041] In this application, the terms "calculate", "judge", "control", "determine", "identify", etc. refer to the operations and processes of a computer system or similar electronic computing device (e.g., controller, processor, etc.).

[0042] Figure 1 A spray fan 100 is shown for spraying water mist, which diffuses into the air and can cool the environment. The spray fan 100 can be used in 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 the bucket. The spray fan 100 can also be used in 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 tap water pipe. In order to illustrate the technical solution of this application, the following is also defined. Figure 1 Front, back, left, right, top and bottom sides shown.

[0043] like Figure 1 and Figure 2 As 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 a fan blade 210 and a first motor 220 that drives the fan blade 210 to rotate. The nozzle 300 is set on the fan assembly 200, specifically on the front 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 follows Figure 1 and Figure 2The arrangement shown is on both sides of the front of the spray fan 100, but it can also be arranged in other locations, which is not limited by this application. The support assembly 400 is used to support the fan assembly 200. The support assembly 400 includes a portion arranged below the fan assembly 200 and portions 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 the external power supply 540. When the battery pack 530 is combined with the first power interface 510 (battery pack interface), at least a portion of the battery pack 530 is exposed from the housing 410 of the support assembly 400.

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

[0045] In some embodiments, the angle between the first power interface 510 and a vertical plane extending along the front-to-back direction of the mist fan 100 is greater than or equal to 0 degrees and less than or equal to 30 degrees. The angle between the first power interface 510 and the vertical plane extending along the front-to-back direction of the mist fan 100 includes the angle between the first power interface 510 and the left side of the vertical plane extending along the front-to-back direction of the mist fan 100, or the angle between the first power interface 510 and the right side of the vertical plane extending along the front-to-back direction of the mist fan 100. Alternatively, the angle between the first power interface 510 and the vertical plane extending along the front-to-back direction of the mist fan 100 may be 10 degrees. Alternatively, the angle between the first power interface 510 and the vertical plane extending along the front-to-back direction of the mist fan 100 may be 18 degrees. Alternatively, the angle between the first power interface 510 and the vertical plane extending along the front-to-back direction of the mist fan 100 may be 28 degrees.

[0046] like Figure 4 As shown, the second power interface 520 is disposed on the housing 410 of the support assembly 400 of the spray fan 100, specifically on the back side of the spray fan 100 (i.e., the rear side of the spray fan 100), opposite the nozzle 300. This prevents water mist from being sprayed outward from the nozzle 300 from splashing onto the interior of the second power interface 520. Optionally, the second power interface 520 includes a matching waterproof protective member 521. When the second power interface 520 is not in use, the waterproof protective member 521 is installed on the second power interface 520 to further prevent water mist from being sprayed outward from the nozzle 300 from splashing onto the second power interface 520. Optionally, the angle between the extension direction of the second power interface 520 and a horizontal plane extending along the front-to-back direction of the spray fan 100 is greater than or equal to 0 degrees and less than or equal to 30 degrees. The extension direction of the second power interface 520 specifically refers to the direction formed by a line connecting the frontmost 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-to-back direction of 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-to-back direction of 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 extending in the front-to-back direction of the spray fan 100 can be 25 degrees. Figure 4 The angle shown is 0 degrees, that is, the extension direction of the second power interface 520 is parallel to the horizontal plane extending in the front-to-back direction of the spray fan 100, so that the user can use the second power interface 520 more conveniently 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 follows: Figure 5 30 degrees shown.

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

[0048] In some embodiments, as Figure 6 and Figure 7 As shown, the power supply assembly 500 further includes a charging circuit 550, and the mist fan 100 further includes a control mainboard 600 and a main control module 610. The control mainboard 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 method of the mist fan 100. The main control module 610 is powered by the power supply assembly 500 and can be disposed on the control mainboard 600.

[0049] In some embodiments, the second power interface 520 is a DC interface, and the external power supply 540 is a DC power supply. In this case, the external power supply 540 can be a battery pack, which can be composed of a group of battery cells. For example, the battery cells can be connected in series to form a single power branch, forming a 1P battery pack. Furthermore, the external power supply 540 can also be DC power provided in other forms. In some embodiments, the second power interface 520 is an AC interface, and the external power supply 540 is AC power, meaning that the second power interface 520 can be connected to 120V or 220V AC mains power. In this case, the power supply assembly 500 also includes an AC-DC conversion circuit to convert the external power supply 540 into DC power. The DC power provided by the external power supply 540, or the DC power converted from the AC power of the external power supply 540, can be converted to DC power of the voltage required by the spray fan 100 by the DC-DC conversion circuit in the power supply assembly 500. Similarly, the DC power from the battery pack 530 can also be converted to DC power of the voltage required by the spray fan 100 by the DC-DC conversion circuit.

[0050] Alternatively, 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). The AC-DC module 551 is used to convert AC power into DC power when the external power supply 540 is AC power. The DC-DC module 552 is used to change the voltage of the DC power converted when the external power supply 540 is AC power, or to change the voltage of the DC power when the external power supply 540 itself is DC power, and output a supply voltage suitable for the first motor 220, the battery pack 530, etc. to power them. At the same time, the DC-DC module 552 can also change the voltage of the DC power output by the battery pack 530, and output a supply voltage suitable for the first motor 220, etc. to power them.

[0051] Alternatively, as Figure 6 As shown, there are bidirectional conversion circuits between the external power supply 540, the AC-DC module 551, the DC-DC module 552 and the battery pack 530, that is, the DC power output by the battery pack 530 can first pass through the DC-DC module 552, and then be converted into AC power through the AC-DC module 551 to output electricity to the outside.

[0052] When charging conditions are met, the main control module 610 controls the charging circuit 550 to use the external power source 540 to charge the battery pack 530. Simultaneously, the main control module 610 controls the external power source 540 to power the mist fan 100. At this point, the second power interface 520 must be electrically connected to the external power source 540, and the first power interface 510 must be electrically connected to the battery pack 530. The charging condition requires that the input power of the external power source 540 is greater than the operating power of the mist fan 100, that is, the input power of the Type-C interface is greater than the operating power of the mist fan 100. The battery pack 530 is charged via the Type-C interface. In this case, the external power source 540 has a higher input power, allowing it to both power the mist fan 100 and charge the battery pack 530. This allows the battery pack 530 to be charged by the external power source 540, reducing the chance of the battery pack 530 running low and unable to power the mist fan 100. Even if the battery pack 530 is low, it can be directly charged using the external power source 540, eliminating the need to replace the battery pack 530, thus improving the battery life of the mist fan 100.

[0053] In some embodiments, when the second power interface 520 is electrically connected to the external power source 540, the first power interface 510 is electrically connected to the battery pack 530, and the input power of the external power source 540 is less than the power required by the spray fan 100 (i.e., the input power of the Type C interface is less than the power required by the spray fan 100), the main control module 610 controls the battery pack 530 and the external power source 540 to jointly power the spray fan 100. In this case, the input power of the external power source 540 is relatively low. To avoid unsatisfactory operating performance of the spray fan 100 when relying solely on the external power source 540, the battery pack 530 and the external power source 540 are used to power 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 power the spray fan 100.

[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 a second power-consuming device, the main control module 610 controls the battery pack 530 to supply power to the second power-consuming device. The second power-consuming device can be any power-consuming device other than the mist fan 100, and this application does not limit this.

[0056] By configuring the second power interface 520 as a bidirectional Type C interface, when the second power interface 520 is connected to an external power source 540, it can charge the battery pack 530 or power the mist fan 100. When the second power interface 520 is connected to a second power-consuming device, the battery pack 530 can power the second power-consuming device. Thus, the mist fan 100 can function not only as a power-consuming device but also as a power supply device.

[0057] In some embodiments, the spray fan 100 further includes a wireless communication module 620, which is used to communicate with a remote device. The wireless communication module 620 uses a Bluetooth or WiFi communication protocol. The remote device can be a mobile phone, a remote control, or any other device that has a Bluetooth or WiFi communication protocol that matches the wireless communication module 620. Figure 7 As shown, the wireless communication module 620 is provided on the control mainboard 600. Optionally, the wireless communication module 620 is a waterproof structure, so that the wireless communication module 620 can be used normally even 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 assembly 500. Specifically, the wireless communication module 620 is powered by the external power supply 540 and / or the battery pack 530. The process of powering the spray fan 100 by the power supply assembly 500 is referred to above and will not be repeated here. Figure 6 As 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 power on and / or power off of the spray fan 100 based on the wireless communication module 620. Specifically, the remote device can remotely and directly control the power on and / or power off of the spray fan 100 based on the wireless communication module 620, or the remote device can remotely control the scheduled power on and / or scheduled power off of the spray fan 100 based on the wireless communication module 620. Optionally, the remote device controls the power on and / or power off 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 spraying from 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 head shaking 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, the medium wind speed gear, and the high wind speed gear based on the wireless communication module 620. Alternatively, the remote device can directly control the wind speed of the spray fan 100 from the lowest gear (i.e., low wind speed gear) to the highest gear (i.e., high wind speed gear) with one click 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 can reach the highest gear with one click.

[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 types of water mist, namely, a first water mist amount, a second water mist amount, a third water mist amount, and a fourth water mist amount, and the amount of water mist increases step by step from the first water mist amount to the fourth water mist amount. The remote device can then control the amount of water mist sprayed by the nozzle 300 to switch step by step between these four water mist amounts, or it can control the water mist sprayed by the nozzle 300 to reach the maximum amount (i.e., the fourth water mist amount) from the minimum amount (i.e., the first water mist amount) in one click. Optionally, when the amount of water mist sprayed by the nozzle 300 includes any number of water mist amounts, the remote device can control the switching of the water mist output of the nozzle 300, and the water mist output reaches the maximum amount in one click.

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

[0063] In some embodiments, the remaining operating time of the mist fan 100 can be displayed on a remote device based on the wireless communication module 620. Specifically, when the mist fan 100 is powered solely by the battery pack 530, the remaining operating time of the mist fan 100 can be displayed based on the remaining power of the battery pack 530. At the same time, the remaining power of the battery pack 530 can also be displayed on the remote device.

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

[0065] In some embodiments, as Figure 7As shown, the support assembly 400 includes a housing 410, which forms a coupling portion 411 and a receiving portion 412. The coupling portion 411 is used to detachably couple the battery pack 530, and the coupling portion 411 forms a space for inserting the battery pack 530. When the battery pack 530 is coupled to the coupling portion 411, at least a portion of the battery pack 530 is exposed from the housing 410. The receiving portion 412 is used to accommodate the second motor 230 and the third motor 240. 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 to the nozzle 300.

[0066] In some embodiments, the second motor 230 and the third motor 240 are both powered by the power supply assembly 500. The second motor 230 and the third motor 240 are specifically powered by the external power supply 540 and / or the battery pack 530. The process of the power supply assembly 500 supplying power to the spray fan 100 is referred to above and will not be repeated here. Figure 6 As shown, the DC-DC module 552 of the charging circuit 550 performs voltage conversion 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 As shown, the second motor 230 is positioned between the coupling portion 411 and the fan assembly 200 along the vertical direction of the spray fan 100. Specifically, it is positioned above the coupling portion 411 and below the fan assembly 200. Thus, when the second motor 230 is in operation, it can control the support portion 400 connected to the fan assembly 200 to swing left and right, thereby controlling the fan assembly 200 to swing left and right.

[0068] In some embodiments, the third motor 240 is disposed in the accommodating portion 412 around the coupling portion 411. Specifically, the third motor 240 is disposed in any position on the front, left side, and right side of the coupling portion 411 around the coupling portion 411. Figure 9 As shown, the third motor 240 is disposed in front of the joint 411. Alternatively, the third motor 240 may be disposed in front of the side of the joint 411. Alternatively, the third motor 240 may be disposed at any position on the left side of the joint 411. Alternatively, the third motor 240 may be disposed at any position on the right side of the joint 411.

[0069] In some embodiments, the joint 411 is a recessed portion of the housing 410 that is open to the environment. Figure 10As shown, the recess extends along the first direction X and is configured to receive at least a portion of the battery pack 530 in a direction parallel to the first direction X. Optionally, the first direction X is substantially parallel to the spray direction of the water mist sprayed by the nozzle 300. The opening direction of the joint 411 is substantially opposite to the spray direction of the nozzle 300, that is, the opening direction of the recess is substantially opposite to the direction of the nozzle 300. The nozzle 300 sprays toward the front side of the spray fan 100, and the opening direction of the joint 411 is toward the rear side of the spray fan 100. Therefore, when the battery pack 530 is installed in the joint 411, it can avoid being splashed by the water mist sprayed by the nozzle 300, thereby ensuring the safety of the battery pack 530. Furthermore, the joint 411 is configured as a recessed portion open to the environment. The joint 411 is not closed relative to the rear end of the mist fan 100. Specifically, the joint 411 is closed on three sides, namely, the left, front, and right sides of the mist fan 100. This makes the joint 411 semi-open, facilitating the replacement of the battery pack 530 should a malfunction occur. Furthermore, the semi-open configuration of the joint 411 further reduces costs and the weight of the mist fan 100. Furthermore, when the battery pack 530 is not installed, the mist fan 100 is smaller and more compact, making it easier to store and carry.

[0070] Optionally, the recess formed by the coupling 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. When at least a portion of the battery pack 530 is inserted into the recess in the coupling portion 411, the first set of electrical contact elements and the second set of electrical contact elements 531 form an electrical connection, enabling the battery pack 530 to at least power the first motor 220. Furthermore, the battery pack 530 can also power the second motor 230 and the third motor 240. The first set of electrical contact elements provided in the recess serves as the first power interface 510, and the second set of electrical contact elements 531 may serve as the plug-in interface for the battery pack 530.

[0071] Alternatively, as Figure 11 As shown, the width W of the recess in the coupling portion 411 along the left-right direction is greater than its height H along the vertical direction. That is, the battery pack 530 is inserted horizontally into the recess formed by the coupling portion 411. As a result, the battery pack 530 is shorter in the vertical direction of the spray fan 100, reducing the overall height of the spray fan 100. This avoids the problem of inserting the battery pack 530 vertically, which would increase the height of the spray fan 100 and make it bulky and difficult to store and carry. Furthermore, inserting the battery pack 530 horizontally also stabilizes the center of gravity of the spray fan 100.

[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 user's pressing operation based on the micro-pressure sensor. Figure 8 As shown, the operation panel 700 is mounted on the front side of the spray fan 100, so that the user can adjust the wind speed of the spray fan 100 at any time when using the spray fan 100. Optionally, the operation panel 700 is made of a waterproof structure, so that even if 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 As shown, the angle B formed between the operation panel 700 and the horizontal plane extending along the front-to-back direction of the spray fan 100 is greater than or equal to 30 degrees and less than or equal to 50 degrees. This allows the user to clearly see the operation panel 700 when using the spray fan 100, and allows the user to easily press buttons at any time during operation. Optionally, the angle B formed between the operation panel 700 and the horizontal plane extending along the front-to-back direction of the spray fan 100 is 35 degrees. Optionally, the angle B formed between the operation panel 700 and the horizontal plane extending along the front-to-back direction of the spray fan 100 is 40 degrees. Optionally, the angle B formed between the operation panel 700 and the horizontal plane extending along the front-to-back direction of the spray fan 100 is 47 degrees.

[0074] In some embodiments, the operation panel 700 includes a power on / off button 710 for controlling the power on and off of the mist fan 100. The operation panel 700 also includes a start / stop button for the mist fan 100's oscillation function, for controlling the left and right oscillation of the mist fan 100. The operation panel 700 also includes a start / stop button for the mist spraying nozzle 300 of the mist fan 100, for controlling whether the mist spraying nozzle 300 sprays outward.

[0075] In some embodiments, the operation panel 700 includes a wind speed adjustment button. When 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 to adjust the wind speed according to needs. The operation panel 700 also includes a one-button maximum wind speed adjustment button. When the spray fan 100 is in the power-on state, the one-button maximum wind speed adjustment button is used to make the spray fan run directly at the maximum wind speed.

[0076] In some embodiments, the operation panel 700 includes an adjustment button for the amount of water mist discharged from the nozzle 300. After the nozzle 300 is in the on state for spraying water mist, the amount of water mist discharged from the nozzle 300 is adjusted step by step through the water mist amount button. Optionally, the water mist amount adjustment button can be a single button, and the water mist amount is adjusted by pressing the water mist amount button multiple times. Optionally, the water mist amount adjustment button can be multiple buttons, and the user can directly press the button corresponding to the required water mist amount to adjust the water mist amount according to needs. The operation panel 700 also includes a one-touch maximum water mist amount adjustment button. After the nozzle 300 is in the on state for spraying water mist, the one-touch maximum water mist amount button causes the nozzle 300 to spray water mist outward according to the maximum water mist amount.

[0077] In some embodiments, the operating panel 700 includes a button for adjusting the swing angle of the fan assembly 200, specifically a button for adjusting the left and right swing angle of the fan assembly 200. When the mist fan 100's swing function is enabled, the swing angle of the fan assembly 200 can be adjusted by pressing the swing angle button. The swing angle of the fan assembly 200 can range from -90 degrees to 90 degrees. A leftward swing angle of the fan assembly 200 is set to a negative angle, while a rightward swing angle is set to a positive angle.

[0078] Optionally, the fan assembly 200's swing angle button is a single button. After pressing this button, the fan assembly 200 first swings to the left at a preset angle. Then, after the fan assembly 200 reaches a swing angle of 90 degrees to the left (i.e., the fan assembly 200 swings to a swing angle of -90 degrees), pressing this button again causes the fan assembly 200 to continue swinging to the right at a preset angle. Optionally, the fan assembly 200's swing angle button is two buttons, including a left swing button and a right swing button, corresponding to swinging to the left and right, respectively. When the user desires the fan assembly 200 to swing to the left, the user presses the left swing button, which causes the fan assembly 200 to swing to the left at a preset angle. If the user desires the fan assembly 200 to continue swinging to the left, the user presses the left swing button multiple times. Similarly, when the user desires the fan assembly 200 to swing to the right, the user presses the right swing button, which causes the fan assembly 200 to swing to the right at a preset angle. If the user desires the fan assembly 200 to continue swinging to the right, the user presses the right swing button multiple times. Optionally, the preset angle can be 5 degrees. Optionally, the preset angle may be 10 degrees. Optionally, the preset angle may be 15 degrees. Optionally, the preset angle may be 30 degrees. Optionally, the preset angle may be any number 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 that displays the remaining operating time of the spray fan 100. The number of indicator lights 720 can be 1, 2, 3, 4, 6, or any other number greater than 1, which is not limited in this application.

[0080] Optionally, when the number of indicator lights 720 is 1: when the power level of the spray fan 100 is 100%, that is, when the remaining operating time of the spray fan 100 is the longest, the indicator light 720 may be green. When the power level of the spray fan 100 reaches a first preset power level, that is, the remaining operating time of the spray fan 100 is relatively long, the indicator light 720 may be yellow. When the power level of the spray fan 100 reaches a second preset power level, that is, the remaining operating time of the spray fan 100 is relatively short and the spray fan 100 cannot maintain operation for a long time, the indicator light 720 may be red to remind the user that the spray fan 100 urgently needs to be charged. 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 one, the example of three indicator lights 720 is provided: when all three indicator lights 720 are on, it indicates that the mist fan 100 has a full charge of 100%; when two indicator lights 720 are on, it indicates that the mist fan 100 has a charge level greater than or equal to a first preset charge level; when only one indicator light is on, it indicates that the mist fan 100 has a charge level greater than or equal to a second preset charge level; and when all indicator lights 720 are off, it indicates that the mist fan 100 has no power at all. The number of indicator lights 720 may also be two, four, six, or any other number greater than one, and this application is not limited thereto.

[0082] In some embodiments, the operation panel 700 may also display the power supply status of the mist fan 100. Specifically, it may display that the mist fan 100 is powered by the external power supply 540 and the battery pack 530 is charging; or it may display that the mist fan 100 is powered by the battery pack 530; or it may display that the mist 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 portions connected to the fan assembly 200 on both the left and right sides. Pitch clips are provided at both the left and right connections between the support assembly 400 and the fan assembly 200, allowing the user to adjust the vertical swing angle of the fan assembly 200 by snapping the pitch clips into place. This allows the user to adjust not only the horizontal swing angle of the fan assembly 200 but also the vertical swing angle of the fan assembly 200, better meeting the user's usage needs.

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

[0085] like Figure 12 As shown, the spray fan 100 can also be placed on a bucket, with a water pipe connected to the bucket. Water in the bucket can be drawn through the pipe to achieve the spray function. Optionally, a clip that mates with the bucket can be provided at the base of the spray fan 100 for attaching the bucket to the spray fan 100. A handle 110 is provided on the top of the spray fan 100. When the spray fan 100 is lifted by the handle 110, the bucket can be lifted along with it, eliminating the need to lift the spray fan 100 and the bucket separately, making the use of the spray fan 100 more convenient.

[0086] like Figure 13 As shown, the spray fan 100 also includes a water interface 800, which can cooperate with the interface groove 414 formed at the bottom of the shell 410. Optionally, the interface groove 414 is a spiral groove, and the outer portion 810 of the water interface 800 that cooperates 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 shell 410. In addition, rotating the water interface 800 can also remove the water interface 800 from the bottom of the shell 410, making it easy to replace the water interface 800 when it is damaged or blocked. Optionally, the inner portion 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 connect the external water pipe to prevent the external water pipe from easily falling off from the interface. The present application sets an interface groove 414 at the bottom of the shell 410, so that the water interface 800 can be stored and fixed at the bottom of the shell 410, so that when an external water pipe is needed, it can be directly connected and used, which is convenient and quick.

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