[0055] Firstly, referring to Figures 1 to 3 This application provides a water system for use with a spray fan, comprising:

[0056] Water source interface 101 includes an inlet 101a and an outlet 101b; the inlet 101a of the water source interface is used to communicate with an external water source liquid.

[0057] Pipe 109 is in liquid communication with water source interface 101. Pipe 109 is also in liquid communication with water pump 102 and one-way valve 103 respectively, so that liquid flows from external water source to water pump 102 through pipe 109 and liquid flows from external water source to one-way valve 103 through pipe 109.

[0058] A water spray pipe 108 is connected to a water pump 102 and a one-way valve 103 for liquid communication; the water spray pipe 108 is also connected to a nozzle 104 for liquid communication; this allows liquid to flow from the water pump 102 to the nozzle 104, or allows liquid to flow from the one-way valve 103 to the nozzle 104; wherein...

[0059] The one-way valve 103 is used for one-way flow from the pipe 109 to the spray pipe 108; the water pump 102 transports liquid from the outlet 101b to the nozzle 104 when it is in operation.

[0060] The water system provided in this application is installed in a spray fan. The water source interface 101 is connected to an external water source outside the spray fan. The external water source can be a static water source without external water pressure or a dynamic water source with external water pressure. The outlet 101b of the water source interface 101 is used to connect the water pump 102 and the one-way valve 103, so that water from the static water source can enter the water pump 102 through the outlet 101b of the water source interface 101, and then enter the nozzle 104 through the water pump 102; or water from the dynamic water source can enter the one-way valve 103 through the outlet 101b of the water source interface 101, and then enter the nozzle 104 through the one-way valve 103. When the external water source connected to water source interface 101 is a static water source, water pump 102 is in operation. The water source system draws water through water pump 102 and flows to nozzle 104. Even if some water passes through check valve 103, it cannot flow back from check valve 103 to water source interface 101, affecting the smooth flow of water and ensuring the water spraying efficiency of the water system under static water source conditions. Similarly, when the external water source connected to water source interface 101 is a dynamic water source, water pump 102 is in a static state. The water pressure of the dynamic water source itself transports water to check valve 103 and water pump 102. Because the conduction direction of water pump 102 requires high water pressure, water flows more easily from check valve 103 to nozzle 104. Even if the water pressure exceeds the requirements of the conduction direction of water pump 102, due to the unidirectional conduction of water pump 102, water cannot flow back from water pump 102 to water source interface 101, affecting the smooth flow of water and still ensuring the water spraying efficiency of the water system.

[0061] Specifically, pipe 109 is connected to water pump 102 and check valve 103 via water source interface 101, and spray pipe 108 forms a water path connecting water pump 102 to nozzle 104 and check valve 103 to nozzle 104. This allows water to flow through water source interface 101 to water pump 102 or check valve 103, and then to nozzle 104. In response to external water pressure, water flows through pipe 109 to check valve 103 and through spray pipe 108 to nozzle 104, forming a unidirectional water path. In response to the absence of external water pressure, water pump 102 draws water through pipe 109 and transports it to spray pipe 108, then to nozzle 104, forming a unidirectional water path.

[0062] In some embodiments, the water system of this application further includes:

[0063] The first tee 105 is directly connected to the pipe 109 in liquid communication; the first tee 105 is also connected to the water pump 102 and the one-way valve 103 in liquid communication respectively; liquid flows into the first tee 105 through the pipe 109; liquid flows directly into the water pump 102 through the first tee 105, and liquid flows directly into the one-way valve 103 through the first tee 105.

[0064] Specifically, refer to Figure 1 and Figure 3 This application connects the outlet 101b of the water source interface 101, the one-way valve 103 and the water pump 102 respectively through the first tee 105, thereby enabling the water source interface 101 to extend through the pipe 109 to the inside of the spray fan to connect the first tee 105, and then connect the one-way valve 103 and the water pump 102, thereby simplifying the water circuit and ensuring the stability of the water circuit in the water circuit system.

[0065] In some embodiments, the water system of this application further includes:

[0066] The second three-way valve 106 is directly liquid-connected to the water spray pipe 108; the second three-way valve 106 is also liquid-connected to the water pump 102 and the one-way valve 103 respectively; the liquid flows directly into the second three-way valve 106 through the water pump 102, and then directly into the water spray pipe 108 through the second three-way valve 106; or, the liquid flows directly into the second three-way valve 106 through the water pump 102, and then directly into the water spray pipe 108 through the second three-way valve 106.

[0067] Specifically, refer to Figure 1 and Figure 3 This application achieves the separate connection of nozzle 104 to check valve 103 and water pump 102 through second three-way valve 106, providing passages from check valve 103 to second three-way valve 106 and from water pump 102 to second three-way valve 106, and connecting second three-way valve 106 to nozzle 104 through water spray pipe 108, simplifying the water path between check valve 103, water pump 102 and nozzle 104, and ensuring the stability of the water path in the water system.

[0068] In some embodiments, the water system of this application further includes a second nozzle 104, a third tee 107, and a component pipe 110; wherein...

[0069] Specifically, refer to Figure 1 and Figure 3The third tee 107 is directly liquid-connected to the water spray pipe 108; the third tee 107 is also directly liquid-connected to the component pipe 110 and the nozzle 104 respectively; the second nozzle 104 is directly liquid-connected to the component pipe 110; liquid flows directly from the second tee 106 into the third tee 107 through the water spray pipe 108, and then directly into the nozzle 104 through the third tee 107, and also directly into the second nozzle 104 through the third tee 107.

[0070] The water system of this application also includes a second nozzle 104b, a component pipe 110, and a third tee 107. The three ports of the third tee 107 are respectively connected to the component pipe 110, nozzle 104a, and spray pipe 108. The component pipe 110 is then connected to the second nozzle 104b to form a water path from the third tee 107 to the second nozzle 104b, thereby forming a water path from the spray pipe 108 to the nozzles 104a and 104b, thus achieving uniform water spraying. The nozzles 104a and 104b can be arbitrarily positioned within the spray fan, ensuring that the spray direction and uniformity meet user requirements.

[0071] The third tee 107 provided in this application connects the second tee 106, nozzle 104a, and second nozzle 104b of the water system, forming a passage from the water pump 102 or the one-way valve 103 to the nozzle 104, simplifying the water system and improving the stability of the water passage.

[0072] In some embodiments, the water source interface of this application further includes a valve 101c, an interface body 101d, a filter screen 101e, and a water outlet cover 101f; wherein

[0073] The inlet 101a is located on the interface body 101d; the outlet 101b is located on the outlet cover 101f;

[0074] A filter screen 101e is provided at the connection between the interface body 101d and the outlet cover 101f; the filter screen 101e is used to seal the connection between the interface body 101d and the outlet cover 101f; a valve 101c is enclosed in the interface body 101d, and the valve 101c is located between the inlet 101a and the filter screen 101e; wherein

[0075] The liquid flows into the water source interface through the inlet 101a, and flows out of the water source interface through the valve 101c, the filter screen 101e, and the outlet 101b in sequence.

[0076] Specifically, refer to Figure 3Different water sources can flow into the water system provided in this application through the water source interface 101. The water source interface 101 includes an interface body 101d and an outlet cover 101f. The outlet cover 101f covers the interface body 101d, a valve 101c is disposed inside the interface body 101d, and a filter screen 101e is disposed at the connection between the interface body 101d and the outlet cover 101f to seal the connection between the interface body 101d and the outlet cover 101f. An inlet 101a is provided on one side of the interface body 101d, and an outlet 101b is provided on one side of the outlet cover 101f, allowing water to flow into the cavity through the inlet 101a and out through the outlet 101b. Through the valve 101c, the water source interface 101 can control the flow of water when connected to a water source; through the filter screen 101e, water can be filtered when passing through the water source interface 101 to prevent blockage and ensure the stability of the water system.

[0077] In some specific embodiments, the water inlet 101a is threaded, allowing it to be screwed onto a garden water pipe or placed directly in a bucket. Water is then drawn by the water pump 102 and flows into the water system through the water source interface 101. The valve 101c can be a ball valve, which controls the on / off state of the water source interface 101 by rotating the ball valve.

[0078] In some specific embodiments, a metal hook is provided inside the outlet 101b, and the pipe 109 is made of soft material. After being inserted into the outlet 101b, the metal hook can hook onto the outer wall of the pipe 109, preventing the pipe 109 from being pulled out of the outlet 101b. A rubber ring is provided between the metal hook of the outlet 101b and the outlet cover 101f, allowing the pipe 109 to be pressed against the rubber ring when inserted into the outlet 101b, thus ensuring that liquid does not leak at the outlet 101b. Specifically, the metal hook is accommodated in the outlet 101b and can move a slight distance relative to the pipe 109 in the direction of insertion / removal, allowing the pipe 109 inserted into the outlet 101b to have a slight relative movement relative to the outlet cover 101f.

[0079] In some embodiments, the filter screen 101e of this application is provided with a sealing part, the filter screen 101e and the sealing part are integrally formed, and the sealing part is disposed between the water outlet cover 101f and the interface body 101d along the liquid flow direction; the filter screen 101e is configured to protrude in a direction away from the water outlet cover 101f.

[0080] Specifically, refer to Figure 3The filter screen 101e can be a metal mesh structure. The sealing part is made of rubber. During the thermoforming process, the metal filter screen 101e is inserted into the sealing part, and then integrally formed with the filter screen 101e after the sealing part cools. The outer diameter of the sealing part should be slightly larger than the inner diameter of the water outlet cover 101f, so that the sealing part can fit tightly inside the water outlet cover 101f, thus providing a sealing effect when the interface body 101d and the water outlet cover 101f are connected. Specifically, the interface body 101d is provided with external threads, and the water outlet cover 101f is provided with internal threads. The interface body 101d and the water outlet cover 101f are screwed together by the internal and external threads, so that the sealing part is clamped between the interface body 101d and the water outlet cover 101f, thereby ensuring the filtration capacity of the filter screen 101e. The filter screen 101e is designed to protrude in the direction away from the water outlet cover 101f in order to maximize the area of ​​the filter screen 101e and improve its filtration capacity.

[0081] In some embodiments, the pipe 109 of this application is provided with branches, through which liquid can flow from the pipe 109 into the water pump 102 and the one-way valve 103 respectively. The system also includes:

[0082] The outlet 101b is connected to the pipe 109, and the liquid flows into the branch through the pipe 109. The branch is connected to the water pump 102 and the one-way valve 103 respectively, so that the liquid flows directly to the water pump 102 through the branch and directly to the one-way valve 103 through the branch.

[0083] Specifically, the pipe 109 is provided with branches, which can be Y-shaped. Specifically, liquid enters the branch from the outlet 101b through the pipe 109 and flows to the pump 102, forming one water path; or, liquid enters the branch from the outlet 101b through the pipe 109 and flows to the check valve 103, forming another water path. The two water paths are identical in the section of the pipe 109 and split into two different paths at the branch point. The check valve 103 also ensures that liquid flowing out of the pump 102 flows back to the pipe 109 from the pump 102, thus ensuring the stability of the water path.

[0084] In some embodiments, the water pump 102 of this application is configured as a plunger pump, and the water pump 102, in the stopped state, conducts unidirectionally from the outlet 101b to the nozzle 104; wherein

[0085] When there is water pressure from an external water source and the water pressure is greater than a preset value, the liquid flows into the branch through the pipe 109 and directly into the water pump 102 through the branch. In response to the water pressure from the external water source, the liquid flows directly from the water pump 102 to the nozzle 104 through the spray pipe 108. The liquid also flows directly into the branch through the pipe 109 and directly into the check valve 103 through the branch. The liquid then flows directly from the check valve 103 to the nozzle 104 through the spray pipe 108.

[0086] Specifically, both the one-way valve 103 and the water pump 102 have one-way flow capability, but the water pump 102 requires high water pressure to conduct when it is stopped. The water pressure driven by the one-way valve 103 in the flow direction is much lower than that of the water pump 102, meaning that water is more likely to flow through the one-way valve 103 to the nozzle 104.

[0087] Specifically, the water pump 102 is configured as a plunger pump or the like, equipped with a check valve 103. When there is water pressure in the external water source and the water pressure is greater than the water pressure threshold of the check valve 103 in the water pump 102, the water pump 102 is turned on in the stopped state, so that the liquid enters the pipe 109 from the outlet 101b of the water source interface, flows into the water pump 102 through the branch of the pipe 109, and flows out of the water pump 102 to the spray pipe 108, and then flows to the nozzle 104.

[0088] In some embodiments, the one-way valve 103 of this application blocks the flow of liquid from the spray pipe 108 to the pipe 109; when the water pump 102 is in operation, the liquid flows from the pipe 109 to the water pump 102 and from the water pump 102 to the spray pipe 108, and cannot flow back from the spray pipe 108 to the pipe 109 through the one-way valve 103.

[0089] Specifically, refer to Figures 1 to 3 The one-way valve 103 is configured to open from pipe 109 to spray pipe 108 and close from spray pipe 108 back to pipe 109. When water pump 102 is operating, suction is generated at pump 102, drawing liquid from pipe 109 to pump 102 and discharging it from pump 102 to spray pipe 108. Since spray pipe 108 connects both pump 102 and one-way valve 103, liquid may backflow in spray pipe 108 to one-way valve 103. Due to the one-way flow function of one-way valve 103, the liquid cannot flow back into pipe 109 after backflowing from spray pipe 108 to one-way valve 103, thus preventing turbulence in the water circuit and ensuring stable liquid flow in the water system.

[0090] Secondly, referring to Figures 4 to 9 This application provides a spray fan, comprising:

[0091] The water system provided by the first aspect of this application, and,

[0092] The base has an internal cavity and an interface groove 201 on its outer surface. The interface groove 201 is used to accommodate a water source interface 101. The base is also used to accommodate a one-way valve 103 and a water pump 102.

[0093] The fan body is located on the upper part of the base, and the nozzle 104 is located on the fan body.

[0094] The spray fan provided in this application includes a base and a fan body. The base has an internal cavity that connects to an interface slot 201, which is located on the outer surface of the base. A water pump holder 205 is located inside the cavity to secure a water pump 102 within it. Specifically, the interface slot 201 is located at the bottom of the base relative to the overall spray fan structure, directly exposed to a static water source. The water pump holder 205 is located at the bottom of the cavity of the base, stably securing the water pump 102 within the cavity and maintaining a fixed relative position. A one-way valve 103 is confined within the cavity, ensuring that the one-way valve 103 is fixed relative to the base, thereby ensuring a stable water flow. It is understood that the placement direction of the one-way valve 103 should be the same as or similar to the water flow direction to maintain unobstructed water flow.

[0095] The fan body is located on the upper part of the base and is used to enclose or partially enclose the nozzle 104. The nozzle 104 is partially or completely enclosed by a portion of the fan body structure to fix its position.

[0097] In some embodiments, refer to Figures 4 to 9 The base provided in this application consists of an upper shell 203 and a lower shell 204. The inner surface of the lower shell 204 and the inner surface of the upper shell 203 form a cavity. The upper shell 203 is located above the lower shell 204, wherein:

[0098] The bottom shell 204 is provided with a through hole 204a that extends through the inner and outer surfaces;

[0099] The outer surface of the bottom shell 204 is recessed in the direction of the upper shell 203 to form an interface groove 201; the inner surface of the bottom shell 204 protrudes in the opposite direction to the upper shell 203 to form a pipe groove 204b; the interface groove 201 communicates with the pipe groove 204b and communicates with the cavity through the through hole 204a; the pipe groove 204b is used to accommodate the pipe 109.

[0100] The bottom shell 204 is also provided with a water pump fixing component 205; the water pump fixing component 205 is used to fix the water pump 102 in the cavity;

[0101] Specifically, refer to Figure 7 and Figure 8 The base of the spray fan provided in this application is assembled from a bottom shell 204 and an upper shell 203. After the upper shell 203 and the bottom shell 204 are assembled, their inner surfaces are connected to form a cavity. The outer surface of the bottom shell 204 is recessed towards the upper shell 203, that is, towards the interior of the cavity, to form an interface groove 201. The interface groove 201 can be detachably snapped into a water source interface 101. The inner surface of the bottom shell 204 protrudes in the opposite direction to the upper shell 203, that is, protrudes outward from the spray fan, to form an outwardly protruding pipe groove 204b. The pipe groove 204b is connected to the interface groove 201, so that the pipe 109 can be detachably accommodated in the combined groove of the pipe groove 204b and the interface groove 201. The user can choose to fix the water pipe in the pipe groove 204b and the interface groove 201, or detach the water pipe from the pipe groove 204b and the interface groove 201, depending on the type of water source. The base shell 204 has a through hole 204a extending through its inner and outer surfaces, allowing the pipe groove 204b to connect from the outside of the spray fan to the cavity of the base via the through hole 204a, thereby allowing the pipe 109 to enter the cavity through the pipe groove 204b. It is understood that a fixing member is provided within the pipe groove 204b, which, together with the protruding wall of the pipe groove 204b, acts on the pipe 109, clamping it within the pipe groove 204b. In a particular embodiment, the pipe groove 204b is spiral-shaped, with one side connected to the interface groove 201 and the other side connected to the through hole 204a.

[0102] Specifically, the bottom shell 204 is provided with a water pump fixing member 205 to fix the water pump 102 in the cavity, thereby ensuring that the water pump 102 can still be fixed relative to the spray fan in the working state, thereby ensuring the stability of the water path of the spray fan.

[0103] Specifically, pipe 109 is connected to the outlet 101b of water source interface 101, check valve 103, and water pump 102, respectively, to enable water to flow from water source interface 101 to check valve 103 and / or water pump 102. A portion of pipe 109 is placed in the cavity, and another portion is exposed to the outside of the spray fan, that is, to provide a passage for water to enter the cavity of the spray fan from the outside of the spray fan.

[0104] In some embodiments, refer to Figures 4 to 9 The spray fan provided in this application also includes a support structure, wherein:

[0105] The support structure includes at least one support component 500, which includes a first tube 501, a bend 502, and a second tube 503. The first tube 501 is partially housed in the bottom shell 204 and is in liquid communication with the bottom shell 204. The second tube 503 is set at a first angle to the first tube 501 and is in liquid communication with the fan body. The first tube 501 and the second tube 503 are in liquid communication through the bend 502.

[0106] The support structure includes at least one support component 500, or two support components 500, which are respectively disposed on both sides of the spray fan. Taking any support component 500 as an example, the support component 500 is composed of a first tube 501, a bending portion 502, and a second part connected to each other. The first tube 501 is partially housed in the bottom shell 204 and partially housed in the upper shell 203, that is, it is inserted into the cavity formed by the bottom shell 204 and the upper shell 203, and is connected to the second tube 503 through the bending portion 502. The second tube 503 is set at a first angle to the first tube 501, and the first angle can be an acute angle, so that the fan body fixed to the second tube 503 can be fixed relative to the base.

[0107] In some embodiments, refer to Figures 4 to 9 The spray fan provided in this application also includes a movable adjustment member 600, and the second tube 503 is pivotally connected to the fan body through the movable adjustment member 600; the fan body adjusts its relative tilt angle with the base through the movable adjustment member 600.

[0108] The movable adjustment component 600 provided in this application can movably connect the second tube 503 to the fan body and control the fixation of the fan body and the second tube 503 at specific angles. In a specific embodiment, the movable connection component can be composed of bolts, nuts, and rubber pads. The second tube 503 and the fan body are pivotally connected by bolts and nuts. A rubber pad is sandwiched between the second tube 503 and the fan body, and the second tube 503 and the fan body are respectively pressed onto the rubber pad. The friction of the rubber pad itself allows the fan body to be suspended at any angle during rotation, thereby allowing the fan body to tilt relative to the base at any angle. The user can thus adjust the wind direction and spray direction of the spray fan.

[0109] In some embodiments, refer to Figures 4 to 9 The water spray pipe 108 provided in this application is housed in the support assembly 500. The water spray pipe 108 extends from the first pipe 501 through the bend 502 into the second pipe 503, and passes through the second pipe 503 to connect with the nozzle 104.

[0110] The water spray pipe 108 provided in this application extends from the first pipe 501 through the bend 502 into the second pipe 503, and then passes through the bend 502 to connect to the nozzle 104, thus realizing a flow path for water to the nozzle 104. The water spray pipe 108 disposed within the support assembly 500 ensures the water spray stability of the spray fan, while simplifying the structure of the spray fan.

[0111] In some embodiments, refer to Figures 4 to 9 The spray fan provided in this application also includes a first switch 701, which is disposed on the upper housing 203 and electrically connected to the water pump 102. The first switch 701 is used to set the water pump 102 to a working state or a stopped state. The first switch 701 is used to control the working state of the water pump 102, so that the user can control the operation of the water pump 102 in response to the type of water source connected.

[0112] In some embodiments, refer to Figures 4 to 9 The spray fan provided in this application also includes a second switch 702, and the fan body also includes a motor 402 and fan blades 401. The motor 402 is connected to the fan blades 401 and is used to drive the fan blades 401 to rotate. The second switch 702 is disposed on the upper housing 203 and is electrically connected to the motor 402. The second switch 702 is used to control the motor 402 to drive the fan blades 401 to rotate. The second switch 702 can control the motor 402, thereby controlling the working state of the spray fan.

[0113] In some embodiments, refer to Figures 4 to 9 The misting fan also includes a handle 403, which is disposed on the fan body and fixed relative to the fan body. Specifically, the handle 403 is located at the highest point in the vertical direction of the fan body, making it convenient for the user to move the misting fan.

[0114] In some embodiments, refer to Figures 4 to 9 The cavity provided in this application includes a battery receiving cavity 204c, which is connected to the inner surface of the bottom shell 204 and the inner surface of the upper shell 203. The battery receiving cavity 204c is used to detachably house the battery pack 707. Specifically, the battery receiving cavity 204c consists of walls connected to the inner surfaces of the bottom shell 204 and the upper shell 203, as well as portions of the inner surfaces of the bottom shell 204 and the upper shell 203. The walls connecting the bottom shell 204 and the upper shell 203 can be fixedly connected by screws or clips. A limiting mechanism is provided inside the battery receiving cavity 204c, through which the battery pack 707 can be detachably fixed inside the battery receiving cavity 204c.

[0115] In some embodiments, refer to Figures 4 to 9The battery housing 204c provided in this application has a movable plate 204d on one side. The movable plate 204d is movably connected to the base, and the connection state between the base and the movable plate 204d is changed to allow the battery pack 707 to be directly exposed from the battery housing 204c. Specifically, the movable plate 204d can be pivotally connected to the base shell 204 behind the spray fan, so that the movable plate 204d can rotate relative to the base shell 204 to open the battery housing 204c. By changing the connection method between the movable plate 204d and the base, the movable plate 204d is partially separated from the battery housing 204c, thereby allowing the battery pack 707 to be directly exposed outside the battery housing 204c, thus making it easy to disassemble or install the battery pack 707.

[0116] In some embodiments, refer to Figures 4 to 9 The outer surface of the base shell 204 is provided with a movable connecting portion, and the movable connecting portion 706 is used for detachably connecting a water bucket, which is used to store water. The base provided in this application can be connected to the water bucket through the base shell 204, thereby making the spray fan and the water bucket form a relatively fixed whole, so that the spray fan can draw water from the water bucket through the water source interface 101 and spray it out through the nozzle 104, which is convenient for users. In particular, the movable connecting portion 706 can be a groove adapted to the shape of the outer edge of the water bucket opening to lock the water bucket, or it can be other fixing parts or fixing mechanisms, without limitation.

[0117] In a complete embodiment, refer to Figures 1 to 9This application provides a spray fan that includes a water system. The water system is connected from the outlet 101b of the water source interface 101 to a first tee 105. The first tee 105 is connected to a water pump 102 and a one-way valve 103. The one-way valve 103 and the water pump 102 are connected to a second tee 106. The second tee 106 is then connected to a third tee 107. The third tee 107 is connected to the first component 104a and the second component 104b of the nozzle 104. This forms two pathways: water source interface 101—one-way valve 103—nozzle 104, and water source interface 101—water pump 102—nozzle 104. Specifically, the water source interface 101 is provided with both a threaded port and a static port. When the inlet 101a of the water source interface 101 is connected to a static water source, in response to the operation of the water pump 102, water is drawn into the water pump 102 and pumped to the nozzle 104, thereby extracting and spraying water from the static water source. At the same time, a small amount of water is simultaneously transported to the one-way valve 103. However, due to the one-way flow function of the one-way valve 103, the water cannot flow back to the water source interface 101 after passing through the one-way valve 103, thus avoiding internal turbulence in the water circuit and affecting the water flow efficiency. When the inlet 101a of the water source interface 101 is connected to a dynamic water source, such as a faucet, there is an initial water pressure that pushes water simultaneously to the water pump 102 and the one-way valve 103. At this time, the liquid can pass through the one-way valve 103 more easily and be further transported to the nozzle 104. Due to the obstruction of the pump itself, water delivered to the pump 102 flows less easily than through the check valve 103. Even if it does flow, the internal structure of the pump 102 is similar to that of the check valve 103, preventing water from flowing back to the water source interface 101. This also avoids internal turbulence in the water path, which would affect the efficiency of water flow. Water transported to the nozzle 104 via the check valve 103 or the pump 102 will first be transported to the third three-way valve 107, and then transmitted through the third three-way valve 107 to the first component 104a and the second component 104b of the nozzle 104, from which the water is evenly sprayed.

[0118] The spray fan provided in this application secures various components of the water system to ensure a stable spraying effect for different water sources. Specifically, the spray fan includes a base and a pipe 109. The base can be placed on any flat surface and connected to a dynamic water source via a water source interface 101; or it can be secured to the upper edge of a water tank via a movable connecting part 706, preventing the water source interface 101, which is movably connected to the base, from inside the water tank, thereby drawing water from a static water source in the tank and transporting it to the nozzle 104. The base consists of an upper shell 203 and a lower shell 204, with the upper shell 203 located above the lower shell 204. The inner surfaces of the upper shell 203 and the lower shell 204 are combined to form a cavity. The cavity is equipped with a water pump fixing component 205, a first slot 704, and a second slot 705. The water pump fixing component 205 is used to fix the water pump 102, the first slot 704 is used to fix the first tee 105, and the second slot 705 is used to fix the second tee 106, thereby providing a stable water circuit connection. The outer surface of the bottom shell 204 is recessed towards the upper shell 203 to form an interface groove 201. The interface groove 201 has fixing components such as hooks 201a and 201b to allow the water source interface 101 to be detachably stored in the interface groove 201. The outer surface of the bottom shell 204 protrudes in the opposite direction to the upper shell 203 to form a pipe groove 204b. The pipe groove 204b is similar to the interface groove 201 and is also equipped with fixing components such as slots 204b1, 204b2, 204b3, and 204b4 to detachably fix the pipe 109 to the pipe groove 204b. The pipe groove 204b connects to the interface groove 201, allowing the water source interface 101 to communicate with the pipe 109. The pipe groove 204b can be spirally arranged on the outer surface of the bottom shell 204. One end of the spiral pipe groove 204b connects to the water source interface 101, and the other end connects to a through hole 204a that penetrates the inner and outer surfaces of the bottom shell 204, allowing the pipe 109 to enter the cavity through the through hole 204a. The pipe 109 can be a hollow flexible tube, which is inserted into the pipe groove 204b and connected to the water source interface 101. Users can choose whether to disassemble the pipe 109 and the water source interface 101 to meet the needs of different usage scenarios. In addition, a first switch 701 and a second switch 702 are provided on the upper shell 203 of the base. The first switch 701 is electrically connected to the water pump 102, and the second switch 702 is electrically connected to the motor 402 of the fan body. The working state of the water pump 102 can be controlled by the first switch 701, and the working state of the motor can be controlled by the second switch 702, thereby controlling the rotation of the fan blade 401.The combined state of the upper shell 203 and the bottom shell 204 forms the inner cavity of the base. The upper shell 203 extends towards the bottom shell 204, and the bottom shell 204 extends towards the upper shell 203 and connects with the plate extending from the upper shell 203, thus forming a battery housing cavity 204c. A movable plate 204d is provided at the rear of the battery housing cavity 204c. The movable plate 204d is pivotally connected to the bottom shell 204 via a shaft, allowing the movable plate 204d to move relative to the base according to the shaft. Opening the movable plate 204d exposes the battery housing cavity 204c from the cavity, making it easy to disassemble the battery pack 707 installed inside the battery housing cavity 204c. It is understood that the battery pack 707 is used to power various electrical components within the spray fan, enabling the corresponding components to perform their functions. It is also understood that the spray fan provided in this application can be powered by an adapter 708, or the adapter 708 can power the battery pack 707 to indirectly power the various electrical components within the spray fan, enabling the corresponding components to perform their functions.

[0119] The spray fan also includes a fan body, which can fix the positions of the first component 104a and the second component 104b of the nozzle 104, such as on both sides of the outer edge of the fan body symmetrical about the center of the fan body, thereby ensuring uniform spraying of water mist. The first component 104a and the second component 104b are connected by a component pipe 110 and a third tee 107. That is, water flows into the third tee 107 through the spray pipe 108, and from the third tee 107 flows into the second component 104b through the component pipe 110, and also flows directly into the first component 104a through the third tee 107. The fan body consists of a main body, a mesh cover, fan blades 401, and a motor 402. The fan blades 401 and the motor 402 are interconnected and contained within the structure formed by the main body and the mesh cover. The spray fan also includes two support components 500, each support component 500 consisting of a first pipe 501, a bend 502, and a second pipe 503. The base has fixing holes, and the first tube 501 is inserted into the fixing holes and positioned parallel to the base, and connected to the second tube 503 through the bending part 502. The second tube 503 forms an acute angle with the first tube 501 and is movably connected to the fan body through a movable adjusting member 600. The fan body can rotate relative to the second tube 503 through the movable adjusting member 600, which ensures that the fan body can be fixed in any position. There is space inside the support assembly 500, and the water spray pipe 108 can extend from the second tee 106 to the fan body through the support assembly 500. Specifically, the support assembly 500 connects to the third tee 107, and then connects to the first assembly 104a and the second assembly 104b. In particular, the support assembly 500 can be formed by bending a single metal tube, that is, the first tube 501, the bending part 502, and the second tube 503 are integrally formed.
