Description

Technical Field

[0001] This application relates to the field of fan technology, and more particularly to a spray fan. Background Technology

[0002] With the advancement of consumer electronics technology and people's increasing demands for quality of life, misting fans have become a common cooling device for daily travel and outdoor activities due to their practicality.

[0003] However, existing misting fans still have significant structural design flaws, resulting in bulky, heavy, and difficult-to-carry fans. Therefore, it is necessary to design a new type of misting fan to address this issue. Utility Model Content

[0004] This application provides a misting fan that solves the problem that misting fans in the related technology still have obvious defects in structural design, resulting in the misting fan being bulky, thick, and cumbersome, making it inconvenient for users to carry.

[0005] This application provides a spray fan; the spray fan includes a housing and a fan assembly. The housing has a first main surface and a second main surface disposed opposite to each other, and at least one peripheral side surface located between the first main surface and the second main surface and connected to the first main surface and the second main surface. The area of ​​each peripheral side surface is smaller than the area of ​​the first main surface and the area of ​​each peripheral side surface is smaller than the area of ​​the second main surface. The first main surface is located on the air inlet side of the spray fan, and the second main surface is located on the air outlet side of the spray fan. The second main surface is provided with air outlet holes. Along the direction from the air inlet side of the spray fan to the air outlet side of the spray fan, the diameter of at least some of the air outlet holes gradually decreases. The fan assembly is disposed corresponding to the air outlet holes and is mounted on the housing.

[0006] The spray fan based on this application achieves a flat overall housing by designing the area of ​​its peripheral side surface to be smaller than the area of ​​the first main surface and the area of ​​its peripheral side surface to be smaller than the area of ​​the second main surface. This flat housing enables a slim and lightweight design, reducing the space occupied by the spray fan and making it easier for users to carry. In the direction from the air inlet side to the air outlet side of the spray fan, the wall surface of the air outlet is designed to be at least partially tapered. This guides the airflow towards the center, concentrating the airflow towards the target area, and also increases the wind speed. Higher wind speed means greater kinetic energy, allowing the airflow to travel further, resulting in higher heat exchange or cooling efficiency. Furthermore, in the direction from the air inlet side to the air outlet side of the spray fan, the wall surface of the air outlet is designed to be at least partially tapered, providing a smooth transition for the airflow. This allows the airflow to smoothly conform to the shape of the outlet wall, greatly reducing airflow separation and the resulting large-scale turbulence, thereby reducing noise.

Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0011] Please refer to Figures 1-4 As shown in the figure, this application embodiment proposes a spray fan 1000, which can achieve a thin and light design, reduce the space occupation of the spray fan 1000, and make it easy for users to carry.

[0012] The spray fan 1000 includes a housing 1100 and a fan assembly 1200. The housing 1100 has a first main surface 110a and a second main surface 110b disposed opposite to each other, and at least one peripheral side surface 110c located between the first main surface 110a and the second main surface 110b and connected to the first main surface 110a and the second main surface 110b. The area of ​​each peripheral side surface 110c is smaller than the area of ​​the first main surface 110a and the area of ​​each peripheral side surface 110c is smaller than the area of ​​the second main surface 110b. The first main surface 110a is located on the air inlet side M of the spray fan 1000, and the second main surface 110b is located on the air outlet side N of the spray fan 1000. The second main surface 110b is provided with an air outlet hole 113a, which points from the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000. The diameter of at least a portion of the air outlet hole 113a gradually decreases. The fan assembly 1200 is provided with an air outlet 113a, and the fan assembly 1200 is mounted on the housing 1100.

[0013] The following combination Figures 1-9 The specific structure of the spray fan 1000 will be described in detail.

[0014] like Figures 1-4 As shown, the spray fan 1000 includes a housing 1100 and a fan assembly 1200.

[0015] The housing 1100 serves as the housing component of the spray fan 1000. The specific structure of the housing 1100 will be described in detail below.

[0016] The housing 1100 has a first main surface 110a and a second main surface 110b, both of which are outer surfaces of the housing 1100 and are disposed opposite to each other. The first main surface 110a and / or the second main surface 110b can be a plane, a curved surface, or a combination of a plane and a curved surface.

[0017] The housing 1100 also has at least one peripheral surface 110c located between the first main surface 110a and the second main surface 110b, and connected to both the first main surface 110a and the second main surface 110b. The peripheral surface 110c can be a plane, a curved surface, or a combination of a plane and a curved surface. For example, when both the first main surface 110a and the second main surface 110b are rectangular surfaces, the number of peripheral surface 110c is four. These four peripheral surface 110c can all be rectangular surfaces (assuming the first main surface 110a and the second main surface 110b are exactly the same size and shape) or they can all be isosceles trapezoidal surfaces (assuming the first main surface 110a and the second main surface 110b are different in size but similar in shape). For example, when both the first main surface 110a and the second main surface 110b are circular surfaces, the number of peripheral side surfaces 110c is one. This peripheral side surface 110c can be a cylindrical surface with equal diameters at both ends (when the size and shape of the first main surface 110a and the second main surface 110b are exactly the same) or a fan-shaped annular surface with unequal diameters at both ends (when the size of the first main surface 110a and the second main surface 110b are different but their shapes are similar).

[0018] The area of ​​each peripheral side surface 110c is smaller than the area of ​​the first main surface 110a, and the area of ​​each peripheral side surface 110c is smaller than the area of ​​the second main surface 110b. For example, when both the first main surface 110a and the second main surface 110b are rectangular surfaces, and all four peripheral side surfaces 110c are rectangular surfaces, by designing that the area of ​​each peripheral side surface 110c is smaller than the area of ​​the first main surface 110a and the area of ​​each peripheral side surface 110c is smaller than the area of ​​the second main surface 110b, the shell 1100 as a whole is a flat cuboid. As another example, when both the first main surface 110a and the second main surface 110b are circular surfaces, and the peripheral side surfaces 110c are cylindrical surfaces, by designing that the area of ​​each peripheral side surface 110c is smaller than the area of ​​the first main surface 110a and the area of ​​each peripheral side surface 110c is smaller than the area of ​​the second main surface 110b, the shell 1100 as a whole is a flat cylinder. The flat housing 1100 enables a slim and lightweight design for the spray fan 1000, reducing its space occupancy and making it easier for users to carry.

[0019] The first main surface 110a is located on the air inlet side M of the spray fan 1000 (that is, the side where the air supply of the spray fan 1000 flows into the fan assembly 1200), and the second main surface 110b is located on the air outlet side N of the spray fan 1000 (that is, the side where the air supply of the spray fan 1000 flows out of the fan assembly 1200).

[0020] The second main surface 110b is provided with an air outlet 113a, which, along the direction from the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000, has a gradually decreasing diameter at least part of it. For example, the diameter of the air outlet 113a may gradually decrease along the direction from the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000 (e.g.) Figure 4 As shown, along the direction from the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000, the distance between the hole wall surface of the air outlet 113a and the hole axis of the air outlet 113a gradually decreases. Alternatively, along the direction from the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000, the diameter of the air outlet 113a can first increase and then decrease. Yet another example is that along the direction from the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000, the diameter of the air outlet 113a can first decrease and then increase. Understandably, in the direction from the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000, the orifice wall of the air outlet 113a is designed to be at least partially tapered. This design serves two purposes: firstly, it guides the airflow towards the center, allowing the air volume to be more concentrated and directed towards the target area; secondly, it increases the wind speed. Higher wind speed means the airflow has greater kinetic energy and can reach further, resulting in higher heat exchange or cooling efficiency. Furthermore, in the direction from the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000, the orifice wall of the air outlet 113a is designed to be at least partially tapered, providing a smooth transition for the airflow. This allows the airflow streamline to smoothly conform to the shape of the orifice wall, greatly reducing airflow separation and the resulting large-scale turbulence, thereby reducing noise.

[0021] like Figures 1-4 As shown, the fan assembly 1200 is used to drive airflow to form an airflow. The specific structure of the fan assembly 1200 will be described in detail below.

[0022] The fan assembly 1200 is provided corresponding to the air outlet 113a, and the fan assembly 1200 is mounted on the housing 1100. The specific installation method between the fan assembly 1200 (specifically the mounting bracket 1210 described below) and the housing 1100 is not limited here, and the designer can make reasonable designs according to actual needs; for example, the fan assembly 1200 (specifically the mounting bracket 1210 described below) can be detachably connected to the housing 1100 by at least one of the following methods: screw connection, snap connection, or plug connection; or, for example, the fan assembly 1200 (specifically the mounting bracket 1210 described below) can also be non-detachably connected to the housing 1100 by adhesive bonding or riveting.

[0023] Based on the spray fan 1000 in this embodiment, by designing the area of ​​the peripheral side 110c to be smaller than the area of ​​the first main surface 110a and the area of ​​the peripheral side 110c to be smaller than the area of ​​the second main surface 110b, the housing 1100 is made to be generally flat. The flat housing 1100 enables the spray fan 1000 to be designed to be thin and light, reducing the space occupied by the spray fan 1000 and making it easier for users to carry. In the direction from the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000, the wall surface of the air outlet 113a is designed to be at least partially constricted. On the one hand, this can guide the airflow to converge towards the center, making the airflow more concentrated and blowing towards the target area. On the other hand, it can increase the wind speed. Higher wind speed means that the airflow has greater kinetic energy and can be blown to a farther place, resulting in higher heat exchange efficiency or cooling efficiency. In addition, in the direction from the air inlet side M of the spray fan 1000 to the air outlet side N of the spray fan 1000, the wall surface of the air outlet 113a is designed to be at least partially tapered, providing a smooth transition for the airflow, allowing the airflow streamline to flow smoothly in accordance with the shape of the hole wall, greatly reducing airflow separation and the resulting large-scale turbulence, thereby reducing noise.

[0024] like Figure 1 , Figure 2 , Figures 5-7 As shown, the housing 1100 includes a water tank 1110, which includes a front panel 111a, a first back panel 111b, and a first side panel 111c. The front panel 111a and the first back panel 111b are disposed opposite to each other. The first side panel 111c is located between the front panel 111a and the first back panel 111b and is sealed to both the front panel 111a and the first back panel 111b. The outer surface of the first back panel 111b is used to form a portion of the aforementioned first main surface 110a (i.e., the aforementioned first main surface 110a includes the outer surface of the first back panel 111b), and a portion of the outer surface of the first side panel 111c is used to form a portion of the aforementioned peripheral side surface 110c (i.e., the aforementioned peripheral side surface 110c includes a portion of the outer surface of the first side panel 111c). The first side plate 111c and the first back plate 111b can be either separate or integrated. When the first side plate 111c and the first back plate 111b are separate, the first side plate 111c can be ultrasonically welded to the first back plate 111b to form a single assembly. When the first side plate 111c and the first back plate 111b are integrated, the first side plate 111c can be integrally formed with the first back plate 111b by injection molding or 3D printing, but is not limited to this method. The panel 111a, together with the first side plate 111c and the first back plate 111b, forms a separate assembly, and the panel 111a can be ultrasonically welded to the assembly formed by the first side plate 111c and the first back plate 111b to form a single unit.

[0025] The housing 1100 also includes a bottom shell 1120, which is disposed on one side of the water tank 1110. The bottom shell 1120 includes a second back plate 112a and a second side plate 112b. The second side plate 112b is connected to the second back plate 112a and together with the first side plate 111c forms a receiving cavity 112c with its opening facing the air outlet side N of the spray fan 1000. The outer surface of the second back plate 112a is used to form the remaining part of the first main surface 110a (that is, the first main surface 110a also includes the outer surface of the second back plate 112a), and the outer surface of the second side plate 112b is used to form the remaining part of the peripheral side surface 110c (that is, the peripheral side surface 110c also includes the outer surface of the second side plate 112b). The second side plate 112b and the second back plate 112a can be either separate or integrated. When the second side plate 112b and the second back plate 112a are separate, the second side plate 112b can be sealed and connected to the second back plate 112a to form another assembly by ultrasonic welding. When the second side plate 112b and the second back plate 112a are integrated, the second side plate 112b can be integrally formed with the second back plate 112a by injection molding or 3D printing, but is not limited to that.

[0026] The housing 1100 also includes a front shell 1130, which has the aforementioned second main surface 110b and the aforementioned air outlet 113a. The front shell 1130 is connected to at least one of the water tank 1110 and the bottom shell 1120 to cover the panel 111a and the opening of the receiving cavity 112c. The specific connection method between the front shell 1130 and the water tank 1110 (and / or the bottom shell 1120) is not limited here; designers can design it reasonably according to actual needs. For example, the front shell 1130 can be detachably connected to the water tank 1110 (and / or the bottom shell 1120) by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the front shell 1130 can also be non-detachably connected to the water tank 1110 (and / or the bottom shell 1120) by, but not limited to, gluing or riveting.

[0027] The water tank 1110 is provided with a through hole 111f, and the face shell 1130 is provided with a mounting hole 113e corresponding to the through hole 111f. When the mounting hole 113e is a threaded hole, the screw passes through the through hole 111f and is threadedly connected to the threaded hole to achieve relative fixation between the water tank 1110 and the face shell 1130. When the mounting hole 113e is a snap-fit ​​hole, the snap-fit ​​pin passes through the through hole 111f and is snap-fit ​​connected to the snap-fit ​​hole to achieve relative fixation between the water tank 1110 and the face shell 1130.

[0028] The bottom shell 1120 is provided with at least one of a buckle 113f and a latch 112d, and the side of the front shell 1130 facing the bottom shell 1120 is provided with at least the other of a buckle 113f and a latch 112d. The buckle 113f and the latch 112d engage to achieve relative fixation of the position between the bottom shell 1120 and the front shell 1130.

[0029] By designing the housing 1100 into three independent parts, namely the water tank 1110, the bottom shell 1120, and the front shell 1130, the water tank 1110 serves as a water storage function and also acts as the outer shell of the spray fan 1000 as part of the housing 1100. This saves materials and reduces production costs. Compared to designing the water tank 1110 inside the spray fan 1000, it also helps to achieve a thinner and lighter design for the spray fan 1000.

[0030] like Figure 1 , Figure 2 , Figures 5-7 As shown, the outer surface of the first back plate 111b is provided with an air inlet 111b1, the outer surface of the front panel 111a is provided with a first through hole 111a1 corresponding to the air inlet 111b1, and the air outlet 113a is provided corresponding to the first through hole 111a1. The water tank 1110 also includes an inner side plate 111d, which surrounds the air inlet 111b1 and the first through hole 111a1. The two ends of the inner side plate 111d are respectively sealed to the front panel 111a and the first back plate 111b, so that the front panel 111a, the first back plate 111b, the first side plate 111c and the inner side plate 111d together form a water storage cavity 111e. The inner side plate 111d and the first back plate 111b can be either separate or integrated. When the inner side plate 111d and the first back plate 111b are separate, the inner side plate 111d can be ultrasonically welded to the first back plate 111b to form a single assembly. When the inner side plate 111d and the first back plate 111b are integrated, the inner side plate 111d can be integrally formed with the first back plate 111b by injection molding or 3D printing, but is not limited to this method. The assembly formed by the panel 111a, the first side plate 111c, the first back plate 111b, and the inner side plate 111d is a separate design, and the panel 111a can be ultrasonically welded to the assembly formed by the first side plate 111c, the first back plate 111b, and the inner side plate 111d to form a single unit.

[0031] The fan assembly 1200 is located within the hollow area 111d1 enclosed by the inner side plate 111d. In this way, while ensuring that the water storage chamber 111e of the water tank 1110 can hold enough water, the fan assembly 1200 and the water tank 1110 are arranged more compactly in space by making reasonable use of the hollow area 111d1 enclosed by the inner side plate 111d. This also helps to achieve the miniaturization design of the spray fan 1000, making it easier for users to carry.

[0032] The fan assembly 1200 includes a mounting bracket 1210, a motor 1220, and a fan blade body 1230. The mounting bracket 1210 is connected to the inner side plate 111d, the motor 1220 is connected to the mounting bracket 1210, and the fan blade body 1230 is connected to the shaft of the motor 1220.

[0033] The specific connection method between the mounting bracket 1210 and the inner side plate 111d is not limited here, and designers can make reasonable designs according to actual needs. For example, the mounting bracket 1210 can be detachably connected to the inner side plate 111d by at least one of the following methods: screw connection, snap connection, or plug connection. Alternatively, the mounting bracket 1210 can be non-detachably connected to the inner side plate 111d by adhesive bonding or riveting. Specifically, the mounting bracket 1210 includes a base 121a, a surrounding wall 121c, and multiple air outlet grilles 121b. The base 121a has a mounting cavity 121a1. The surrounding wall 121c is arranged circumferentially around the base 121a and spaced apart from it. The multiple air outlet grilles 121b are located in the gap between the base 121a and the surrounding wall 121c and are arranged circumferentially around the base 121a. One end of each air outlet grille 121b is connected to the base. 121a is connected, and the other end of the plurality of air outlet grilles 121b is connected to the enclosure 121c. The outer side of the enclosure 121c is provided with at least one of a snap-fit ​​flange 111g and a snap-fit ​​groove 121d. The surface of the inner side plate 111d is provided with at least another of a snap-fit ​​flange 111g and a snap-fit ​​groove 121d. The snap-fit ​​flange 111g and the snap-fit ​​groove 121d are engaged to achieve relative fixation of the position between the mounting bracket 1210 and the inner side plate 111d.

[0034] The specific connection method between the motor 1220 and the mounting bracket 1210 is not limited here, and designers can make reasonable designs according to actual needs; for example, the motor 1220 can be detachably connected to the mounting bracket 1210 by at least one of the following methods: screw connection, snap connection, or plug connection; or, for example, the motor 1220 can be non-detachably connected to the mounting bracket 1210 by adhesive bonding or riveting. Specifically, the motor 1220 is located in the mounting cavity 121a1 of the base 121a and is connected to the base 121a by screws.

[0035] The specific connection method between the fan blade body 1230 and the motor 1220 shaft is not limited here. Designers can make reasonable designs according to actual needs. For example, the fan blade body 1230 can be detachably connected to the motor 1220 shaft by at least one of the following methods: screw connection, snap connection, or plug connection.

[0036] By designing the mounting bracket 1210, motor 1220 and fan blade body 1230, the motor 1220 is connected to the inner side plate 111d of the water tank 1110 through the mounting bracket 1210. The motor 1220 drives the fan blade body 1230 to rotate, and the rotation of the fan blade body 1230 promotes airflow to form airflow, thereby achieving the purpose of cooling.

[0037] The water tank 1110 also includes an air inlet hood 111h, which is located within the hollow area 111d1 enclosed by the inner side plate 111d and adjacent to the air inlet hole 111b1. The air inlet hood 111h is connected to the inner side plate 111d. The air inlet hood 111h and the inner side plate 111d can be either separate or integrated. When the air inlet hood 111h and the inner side plate 111d are separate, the air inlet hood 111h can be sealed and connected to the inner side plate 111d to form a combined unit by ultrasonic welding. When the air inlet hood 111h and the inner side plate 111d are integrated, the air inlet hood 111h can be integrally formed with the inner side plate 111d by injection molding or 3D printing, but is not limited to this method.

[0038] like Figure 1 , Figure 2 , Figures 5-8As shown, the outer surface of panel 111a is also provided with a water outlet 111a2 communicating with the water storage chamber 111e of water tank 1110, and the outer surface of face shell 1130 is also provided with a second through hole 113b corresponding to the water outlet 111a2; the spray fan 1000 also includes a spray assembly 1300, which includes an atomizing element 1310 and a sealing element 1320; the atomizing element 1310 is provided corresponding to the water outlet 111a2, and the atomizing element 1310 is used to atomize the water in the water storage chamber 111e of water tank 1110 and form a spray; the sealing element 1320 is used to seal the gap between the atomizing element 1310 and panel 111a at the water outlet 111a2. The atomizing element 1310 may include, but is not limited to, an ultrasonic atomizer, an atomizing plate 131a, or a piezoelectric nozzle; the sealing element 1320 may include, but is not limited to, an elastic sealing ring 132a or a sealing adhesive layer. By designing the atomizing component 1310, the atomizing component 1310 is used to atomize the water in the water storage chamber 111e of the water tank 1110 and form a spray (formed by countless tiny water droplets). The heat absorption process accompanying the evaporation of the spray can carry away the heat in the air blown out from the air outlet 113a, making the air blown out from the air outlet 113a truly cooled, thereby further enhancing the cooling and heat-relieving effect. By designing the sealing component 1320, the sealing component 1320 is used to seal the gap between the atomizing component 1310 and the panel 111a at the water outlet 111a2, preventing water leakage at the water outlet 111a2 of the water tank 1110, and achieving a good sealing effect. The motor 1220 drives the fan blade body 1230 to rotate. The rotation of the fan blade body 1230 promotes airflow to form airflow (i.e., wind). At this time, the atomizing element 1310 atomizes the water in the water storage chamber 111e of the water tank 1110 and forms a spray. The spray is sprayed out from the second through hole 113b of the shell 1130. The spray evaporates and absorbs heat, carrying away the heat in the wind blown out from the air outlet 113a, so as to achieve the purpose of cooling and relieving heat.

[0039] Specifically, the outer surface of panel 111a is also provided with mounting groove 111a3, which surrounds water outlet 111a2; atomizing component 1310 includes atomizing plate 131a, and sealing component 1320 includes elastic sealing ring 132a. The elastic sealing ring 132a is fitted over the atomizing plate 131a, and the elastic sealing ring 132a is interference-fitted with the groove wall of mounting groove 111a3 to position the atomizing plate 131a on panel 111a. The spray fan 1000 also includes a first sealing plug 1400, which is movably connected to face shell 1130 to open or close the second through hole 113b of face shell 1130. The first sealing plug 1400 can be rotatably connected to the faceplate 1130. When the user needs to use the spray function of the spray fan 1000, the first sealing plug 1400 is rotated to open the second through hole 113b, and the spray formed by the atomizing plate 131a can be sprayed out from the second through hole 113b. When the user does not need to use the spray function of the spray fan 1000, the first sealing plug 1400 is rotated to close the second through hole 113b. Alternatively, the first sealing plug 1400 can be slidably connected to the faceplate 1130. In this case, when the user needs to use the spray function of the spray fan 1000, the first sealing plug 1400 is slid to open the second through hole 113b, and the spray formed by the atomizing plate 131a can be sprayed out from the second through hole 113b. When the user does not need to use the spray function of the spray fan 1000, the first sealing plug 1400 is slid to close the second through hole 113b.

[0040] By designing the atomizing element 1310 as an atomizing plate 131a and the sealing element 1320 as an elastic sealing ring 132a, the elastic sealing ring 132a is arranged around the atomizing plate 131a, which can prevent the rigid atomizing plate 131a from directly contacting the rigid panel 111a and causing damage to the atomizing plate 131a. By designing the mounting groove 111a3 on the outer surface of the panel 111a, the elastic sealing ring 132a is interference-fitted with the groove wall of the mounting groove 111a3. On the one hand, it can effectively seal the gap between the atomizing plate 131a and the panel 111a at the water outlet 111a2, preventing water leakage at the water outlet 111a2 of the water tank 1110 and playing a good sealing role. On the other hand, it can achieve relative fixation between the atomizing plate 131a and the panel 111a, reducing the assembly difficulty between the atomizing plate 131a and the panel 111a. By designing the first sealing plug 1400, the first sealing plug 1400 can close the second through hole 113b of the faceplate 1130, thereby achieving a double seal in conjunction with the design of the aforementioned sealing element 1320. Of course, the sealing element 1320 may also include a sealing adhesive layer, in which case the atomizing plate 131a achieves relative fixation between its position and the panel 111a, and achieves a seal with the panel 111a at the water outlet 111a2, through the sealing adhesive layer.

[0041] The outer surface of the first side plate 111c is provided with a water inlet 111c1 that communicates with the water storage chamber 111e of the water tank 1110. The spray fan 1000 also includes a second sealing plug 1910, which is movably connected to the first side plate 111c to open or close the water inlet 111c1. The second sealing plug 1910 can be rotatably connected to the first side plate 111c. When the user needs to add water to the water storage chamber 111e of the water tank 1110, the second sealing plug 1910 is rotated to open the water inlet 111c1, allowing water to flow from the water inlet 111c1 into the water storage chamber 111e of the water tank 1110. When the water storage chamber 111e of the water tank 1110 is full of water, the second sealing plug 1910 is rotated to close the water inlet 111c1. The second sealing plug 1910 can also be connected to the first side plate 111c by a sliding connection. When the user needs to fill the water storage chamber 111e of the water tank 1110 with water, the second sealing plug 1910 is slid to open the water inlet 111c1, so that water flows from the water inlet 111c1 into the water storage chamber 111e of the water tank 1110. After the water storage chamber 111e of the water tank 1110 is filled with water, the second sealing plug 1910 is slid to close the water inlet 111c1.

[0042] like Figure 1 , Figure 2 , Figures 5-7 As shown, the outer surface of the faceplate 1130 is also provided with a third through hole 113c communicating with the aforementioned receiving cavity 112c; the spray fan 1000 also includes a control component 1500, which includes a main control board 1510 and a first switch 1520. The main control board 1510 is located inside the receiving cavity 112c and connected to the bottom shell 1120. The first switch 1520 is electrically connected to the main control board 1510 and exposed through the third through hole 113c. The first switch 1520 is used to generate a first electrical signal under the operation of the user. The controller of the main control board 1510 controls the speed of the aforementioned motor 1220 according to the first electrical signal.

[0043] The main control board 1510 can be a rigid circuit board, a flexible circuit board, or a combination of both. It should be noted that when the main control board 1510 is a flexible circuit board, the control component 1500 may also include a reinforcing plate, which is disposed on one side of the flexible circuit board to provide support. The specific connection method between the main control board 1510 and the base shell 1120 is not limited here; designers can design it reasonably according to actual needs. For example, the main control board 1510 can be detachably connected to the base shell 1120 by at least one of the following methods: screwing, snap-fitting, or plugging. Alternatively, the main control board 1510 can be non-detachably connected to the base shell 1120 by, but not limited to, adhesive bonding or riveting. The atomizing component 1310 can be electrically connected to the main control board 1510 via a wire, and the motor 1220 can be electrically connected to the main control board 1510 via another wire.

[0044] The first switch 1520 is used to generate a first electrical signal under user operation. The controller of the main control board 1510 controls the speed of the motor 1220 according to the first electrical signal. For example, by operating the first switch 1520 multiple times, the user can make the motor 1220 operate in the following sequence: start (user operates the first switch 1520 for the first time, at which time the motor 1220 operates at the first speed) → second speed (user operates the first switch 1520 for the second time) → third speed (user operates the first switch 1520 for the third time) → fourth speed (user operates the first switch 1520 for the fourth time) → fifth speed (user operates the first switch 1520 for the fifth time) → stop (user operates the first switch 1520 for the sixth time, at which time the speed of the motor 1220 is zero). The first switch 1520 can also be a button. In this case, the first electrical signal is generated by pressing the button. Each time the button is pressed, the button generates a first electrical signal. Thus, by pressing the button multiple times, the user can make the controller of the main control board 1510 control the speed of the motor 1220 according to the first electrical signal. The first switch 1520 can also be a knob. In this case, the first electrical signal is generated by rotating the knob. Each time the knob is rotated, the knob generates a first electrical signal. In this way, the user can rotate the knob multiple times to make the controller of the main control board 1510 control the speed of the motor 1220 according to the first electrical signal.

[0045] like Figure 1 , Figure 2 , Figures 5-7 As shown, the outer surface of the faceplate 1130 is also provided with a fourth through hole 113d that communicates with the receiving cavity 112c; the spray fan 1000 also includes a display module 1600, which is set corresponding to the fourth through hole 113d and electrically connected to the main control board 1510. The display module 1600 is used to display the current wind speed level of the spray fan 1000.

[0046] The display module 1600 may include multiple digital tubes electrically connected to the main control board 1510. When the motor 1220 operates at the first speed mentioned above, the multiple digital tubes can display "F1". When the motor 1220 operates at the second speed mentioned above, the multiple digital tubes can display "F2". When the motor 1220 operates at the third speed mentioned above, the multiple digital tubes can display "F3". When the motor 1220 operates at the fourth speed mentioned above, the multiple digital tubes can display "F4". When the motor 1220 operates at the fifth speed mentioned above, the multiple digital tubes can display "F5". Of course, the display module 1600 may also include a display screen electrically connected to the main control board 1510. When the motor 1220 operates at the first speed mentioned above, the display screen can directly display "Current wind speed is level one". When the motor 1220 operates at the second speed mentioned above, the display screen can directly display "Current wind speed is level two". When the motor 1220 operates at the third speed mentioned above, the display screen can directly display "Current wind speed is level three". When the motor 1220 operates at the fourth speed mentioned above, the display screen can directly display "Current wind speed is level four". When the motor 1220 operates at the fifth speed mentioned above, the display screen can directly display "Current wind speed is level five".

[0047] By designing the display module 1600, users can easily understand the current wind speed setting of the spray fan 1000 by directly observing the display module 1600, thereby improving the ease of use of the spray fan 1000.

[0048] like Figure 1 , Figure 2 , Figures 5-7 As shown, the spray fan 1000 also includes a battery 1700, which is located inside the housing 112c and connected to the bottom shell 1120. The battery 1700 is electrically connected to the main control board 1510. The outer surface of the second back plate 112a is provided with a fifth through hole 112a1. The control assembly 1500 also includes a charging interface 1530, which is electrically connected to the main control board 1510 and exposed through the fifth through hole 112a1. The charging interface 1530 is used to connect to an external power source via a data cable so that the external power source supplies power to the battery 1700.

[0049] The specific connection method between the battery 1700 and the base casing 1120 is not limited here; designers can design it reasonably according to actual needs. For example, the battery 1700 can be detachably connected to the base casing 1120 by at least one of the following methods: snap-fit ​​or plug-in. The charging interface 1530 can be a USB interface or a Type-C interface. The external power source can include, but is not limited to, AC power or a power bank.

[0050] By designing the storage battery 1700 and charging interface 1530, when the storage battery 1700 has too low a power or zero power, the charging interface 1530 can be connected to an external power source via a data cable, so that the external power source can charge the storage battery 1700. Compared with using dry batteries, the storage battery 1700 can be recycled multiple times, reducing environmental pollution.

[0051] like Figure 1 , Figure 2 , Figures 5-7 As shown, the outer surface of the faceplate 1130 is also provided with a sixth through hole 113g that communicates with the aforementioned receiving cavity 112c; the control assembly 1500 also includes a second switch 1540, which is electrically connected to the main control board 1510 and exposed through the sixth through hole 113g. The second switch 1540 is used to generate a second electrical signal under the user's operation, and the controller of the main control board 1510 controls the atomization level of the aforementioned atomizing component 1310 according to the second electrical signal.

[0052] The second switch 1540 is used to generate a second electrical signal under user operation. The controller of the main control board 1510 controls the atomization level of the atomizing element 1310 according to the second electrical signal. For example, by operating the second switch 1540 multiple times, the user can make the atomizing element 1310 operate in the following sequence: first atomization level (user operates the first switch 1520 for the first time) → second atomization level (user operates the first switch 1520 for the second time) → third atomization level (user operates the first switch 1520 for the third time). The second switch 1540 can also be another button. In this case, the second electrical signal is generated by pressing the other button. Each time the other button is pressed, it generates a second electrical signal. Thus, by pressing the other button multiple times, the user can make the controller of the main control board 1510 control the atomization level of the atomizing element 1310 according to the second electrical signal. The second switch 1540 can also be another knob. In this case, the second electrical signal is generated by rotating the other knob. Each rotation of the other knob generates a second electrical signal. Thus, by rotating the other knob multiple times, the controller on the main control board 1510 controls the atomization level of the atomizing element 1310 according to the second electrical signal. It should be noted that the particle diameter of the spray formed by the atomizing element 1310 at the first atomization level is greater than the particle diameter of the spray formed by the atomizing element 1310 at the second atomization level, which is greater than the particle diameter of the spray formed by the atomizing element 1310 at the third atomization level.

[0053] Of course, the aforementioned display module 1600 can also be used to display the current atomization level of the spray fan 1000; when the display module 1600 includes multiple digital tubes electrically connected to the main control board 1510, if the atomizing element 1310 operates at the first atomization level, the multiple digital tubes can display "P1"; if the atomizing element 1310 operates at the second atomization level, the multiple digital tubes can display "P2"; if the atomizing element 1310 operates at the third atomization level, the multiple digital tubes can display "P2"; It can display "P3"; when the display module 1600 includes a display screen electrically connected to the main control board 1510, if the atomizing element 1310 operates according to the first atomization level mentioned above, the display screen can directly display "Current atomization level is level one"; if the atomizing element 1310 operates according to the second atomization level mentioned above, the display screen can directly display "Current atomization level is level two"; if the atomizing element 1310 operates according to the third atomization level mentioned above, the display screen can directly display "Current atomization level is level three".

[0054] The spray fan 1000 also includes a protective sheet 1920, which is light-transmitting. The protective sheet 1920 is positioned corresponding to the fourth through hole 113d and connected to the faceplate 1130. The protective sheet 1920 prevents the display module 1600 from being exposed, thus providing good protection for the display module 1600.

[0055] like Figure 9 As shown, at least one of the first main surface 110a and at least one peripheral side surface 110c is provided with a storage groove 110d; the spray fan 1000 also includes a bracket 1800, which is movably connected to the housing 1100, and the bracket 1800 can switch between a stored state within the storage groove 110d and a supported state extending out of the storage groove 110d. Specifically, the edge of the outer surface of the second back plate 112a and the outer surface of the second side plate 112b are recessed inward to form the storage groove 110d. The bracket 1800 has a semi-frame structure (such as a U-shape), and the two connecting ends of the bracket 1800 are rotatably connected to the second side plate 112b. When the bracket 1800 is in the stored state within the storage groove 110d, the user can directly hold the spray fan 1000. When the bracket 1800 is in the supported state extending out of the storage groove 110d, the user can directly place the spray fan 1000 on an external carrier such as a desktop. This allows users to choose between a handheld spray fan 1000 or place the spray fan 1000 directly on an external carrier, depending on the usage scenario, thus improving the ease of use of the spray fan 1000.
