Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0039] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0044] Please see Figures 1 to 2One or more embodiments of this application provide an air supply device 100, which includes a support structure 10, a body 11, a head 12, an evaporative cooling pad 13, a water inlet 14, and a water outlet 15. The body 11 includes a main body 111 and a water tank 112. The main body 111 includes a receiving cavity and an opening communicating with the receiving cavity, and the water tank 112 is fitted into the receiving cavity. The head 12 is fitted onto the body 11 and has an airflow channel 121 formed therein, communicating with the opening of the receiving cavity. The evaporative cooling pad 13 is fitted onto the support structure 10. The water inlet 14 connects the water tank of the air supply device 100 to the support structure 10. The water outlet 15 connects the water tank of the air supply device 100 to the support structure 10.

[0045] Thus, during the operation of the air supply device, the water inlet 14 transports water from the water tank of the air supply device 100 to the support structure 10. The water flowing into the support structure 10 wets the evaporative cooling pad 13. Finally, any excess water in the evaporative cooling pad 13 is transported back to the water tank of the air supply device 100 through the water outlet 15. At the same time, the airflow blown out of the duct can carry away and mix the moisture in the evaporative cooling pad 13, thereby achieving a cool air effect below room temperature.

[0046] Further, please see Figures 3 to 7 The support structure 10 includes a bracket 101 and a water distribution component 102. The water distribution component 102 and the bracket 101 are separate units, which facilitates the disassembly, assembly, and maintenance of the water distribution component 102 and the bracket 101. Furthermore, the water distribution component 102 enables the connection between the bracket 101 and the water inlet component 14, which is beneficial for the flexible assembly of the bracket 101.

[0047] Specifically, please see Figures 1 to 4 The bracket 101 has a mounting cavity 1011 for assembling the evaporative cooling pad 13 of the air supply device 100. The bracket 101 also has a first connecting port 10121 that communicates with the mounting cavity 1011. The evaporative cooling pad 13 is detachably attached to the mounting cavity 1011. The water distribution component 102 has a flow channel 1021 and is detachably attached to the bracket 101, with its outlet 1023 communicating with the first connecting port 10121.

[0048] Understandably, during the operation of the air supply device 100, the water inlet 14 transports the water in the water tank 112 to the flow channel 1021 of the water distributor 102. Then, the water in the flow channel 1021 flows into the mounting cavity 1011 through the first connecting port 10121 and wets the wet curtain 13. Finally, the excess water in the wet curtain 13 flows out from the second connecting port 10122 and is transported back to the water tank 112 via the water outlet 15. At the same time, the airflow blown out of the flow duct can carry out and mix the moisture in the wet curtain 13, thereby achieving a cooling effect below room temperature.

[0049] In this application, by separating the water distribution component 102 from the bracket 101, it is convenient to disassemble and repair the water distribution component 102 and the bracket 101; and by using the water distribution component 102 to connect the bracket 101 and the water inlet component 14, it is beneficial to the flexible assembly of the bracket 101.

[0050] In some embodiments, see Figure 4 and Figure 5 The bracket 101 is also provided with a second communication port 10122 that communicates with the mounting cavity 1011. The first communication port 10121 and the second communication port 10122 are respectively located on the two opposite surfaces of the bracket 101.

[0051] Under normal circumstances, when the bracket 101 is fitted into the air passage 121 of the head unit 12, the surface of the bracket 101 with the first connecting port 10121 and the surface of the bracket 101 with the second connecting port 10122 are spaced apart relative to each other along the direction of gravity. Thus, the first connecting port 10121 and the second connecting port 10122 are spaced apart along the direction of gravity. In this way, the water entering the mounting cavity 1011 through the first connecting port 10121 can flow downward under the action of gravity and wet the wet curtain 13. At the same time, after wetting the wet curtain 13, the excess water will also flow downward under the action of gravity to flow out from the second connecting port 10122, and finally be transported back to the water tank 112 through the water outlet 15.

[0052] Further, please see Figure 4 and Figure 5 The bracket 101 has an axis (such as...) Figure 2 As shown in X), the axis passes through the center point of the first connecting port 10121 and the center point of the second connecting port 10122, and the bracket 101 is symmetrical about the axis.

[0053] Understandably, in the existing technology, a support structure 10 is attached to both ends of the fan blades inside the head 12 to ensure the cooling effect of the air supply device 100. Therefore, two brackets 101 need to be installed inside the head 12. However, the space inside the head 12 is small, and the water inlet pipe can only be led out from one end. This means that the two brackets 101 need to be adapted to the installation space when assembled, and the two brackets 101 are not mirror images, resulting in different structures for the two brackets 101. As a result, two sets of molds are required when producing the two brackets 101, which affects the overall cost of the machine.

[0054] In this application, the direction of the axis coincides with the direction of gravity. The opposite sides of the support 101 along the axial direction are defined as the upper and lower sides, and the opposite sides of the support 101 along the direction perpendicular to the axis are defined as the left and right sides. Therefore, the left-side structure of the support 101 about the axis is equivalent to the right-side structure of the support 101 about the axis. Thus, with a support 101 installed at both ends along the axial direction of the fan blade inside the head 12, the two supports 101 can be mirror-arranged within the head 12, and their positions can be interchanged. Assembly is flexible and convenient, and the two supports 101 can be produced using a single mold, saving costs.

[0055] In addition, please see Figure 6 and Figure 7 The water distribution component 102 is about its own longitudinal axis (e.g., Figure 4 (As shown in the Y diagram) Symmetrical. In this way, the water distribution component 102 can adapt to the position of the water inlet component 14, so that its own water inlet 1022 is arranged facing the left or right side of the bracket 101, which is beneficial to improving the flexibility and versatility of the assembly of the wet curtain 13 and the water distribution component 102.

[0056] In some embodiments, see Figure 4 and Figure 5 The bracket 101 also has a water storage cavity 1012 that connects the mounting cavity 1011 and the second communication port 10122.

[0057] It is understandable that excess water can be collected in the water storage chamber 1012 so that the water can be discharged through its second connecting port 10122. When the excess water exceeds the drainage efficiency of the second connecting port 10122, the water storage chamber 1012 can better accommodate the excess water to reduce the chance of water accumulation and overflow.

[0058] In some embodiments, see Figure 4 and Figure 5 The bracket 101 includes several side plates, all of which enclose a frame. The frame has a through mounting cavity 1011. A first connecting port 10121 and a second connecting port 10122 are respectively disposed on two opposite side plates of the frame. Thus, the bracket 101 has a simple structure, which helps to save production costs.

[0059] In some embodiments, see Figure 4 and Figure 5The side plate with the first connecting port 10121 is defined as the first side plate 1013, and the first connecting port 10121 extends along the longitudinal direction of the first side plate 1013. The water distribution component 102 has an inlet 1022 and an outlet 1023 that communicate with the flow channel 1021. There are multiple outlets 1023, and all outlets 1023 are spaced apart on the same side surface of the water distribution component 102 along the longitudinal direction of the water distribution component 102.

[0060] When the water distribution component 102 is detachably connected to the bracket 101, all water outlets 1023 are connected to the first connecting port 10121.

[0061] Understandably, during the operation of the air supply device 100, the water inlet 14 transports the water in the water tank 112 through the water inlet 1022 of the water distributor 102 to the flow channel 1021 of the water distributor 102. Then, the water in the flow channel 1021 flows into the installation cavity 1011 through the water outlet 1023 and the first connecting port 10121, wetting the wet curtain 13. Finally, the excess water in the wet curtain 13 flows out from the second connecting port 10122 and is transported back to the water tank 112 via the water outlet 15. By opening multiple water outlets 1023 on the water distributor 102, this application can improve the water output and water output efficiency of the water distributor 102 to ensure the wetting effect of the wet curtain 13. At the same time, it can further ensure that the airflow blown out of the flow channel continuously carries out and mixes the water in the wet curtain 13, thereby achieving a cold air effect below room temperature.

[0062] It should be noted that the specific design of the water distribution component 102 is not limited. For example, in this application, the water distribution component 102 is a pipe.

[0063] In some embodiments, see Figure 4 and Figure 5 The bracket 101 also includes two limiting members 1015. Both limiting members 1015 protrude from the side of the first side plate 1013 away from the mounting cavity 1011 and are respectively disposed on opposite sides of the first connecting port 10121 along the width direction of the first side plate 1013.

[0064] It is understandable that the water distribution component 102 is assembled between two limiting components 1015. The limiting components 1015 can improve the stability of the assembly of the water distribution component 102 to prevent the water distribution component 102 from shifting.

[0065] In some embodiments, see Figure 5 and Figure 6 The bracket 101 is provided with a fastening part 1017, and the water distribution component 102 is provided with a mating part 1024. The fastening part 1017 and the mating part 1024 fasten to each other to realize the detachable assembly of the bracket 101 and the water distribution component 102.

[0066] In some embodiments, see Figure 6 and Figure 7 The water distribution component 102 is bent at least one end along its longitudinal direction to form a limiting part 1025. When the water distribution component 102 is detachably attached to the bracket 101, the limiting part 1025 is in a limiting fit with the side plate attached to one end of the first side plate 1013.

[0067] It is understandable that the water distribution component 102 can be fitted to the first side plate 1013 and the side plate connected to one end of the first side plate 1013 respectively. This can improve the ease of assembly for users and help improve the stability of the assembly of the water distribution component 102, so as to avoid the water distribution component 102 from shifting.

[0068] In some embodiments, see Figure 4 and Figure 5 The side plate with the second communication port 10122 is defined as the second side plate 1014. The bracket 101 also includes a first baffle 1016. A first baffle 1016 is respectively attached to both sides of the frame along the through direction of the mounting cavity 1011, and each first baffle 1016 is connected to the second side plate 1014 and the side plates attached to both ends of the second side plate 1014, and together they form a water storage cavity 1012.

[0069] In some embodiments, see Figure 4 and Figure 5 The second side plate 1014 includes a first section 10141 and a second section 10142 connected to each other. The ends of the first section 10141 and the second section 10142 that are opposite to each other are inclined towards the mounting cavity 1011. The second connecting port 10122 is opened at the connection between the first section 10141 and the second section 10142.

[0070] Understandably, the connection point between the first segment 10141 and the second segment 10142 is the lowest point of the second side plate 1014 along the direction of gravity. When excess water flows onto the second side plate 1014, it can flow to the second connecting port 10122 under the guiding action of the first segment 10141 and the second segment 10142. In this way, the efficiency of water drainage can be improved, thereby reducing the probability of water accumulation and overflow.

[0071] In some embodiments, see Figure 4 and Figure 5 The bracket 101 also includes a second baffle 1018, which is disposed on the side of the frame near the fan blades and motor of the air supply device 100; in the air supply direction along the air flow channel 1021, the projection of the motor is included in the projection of the second baffle 1018.

[0072] Understandably, the two support structures 10 are respectively arranged on opposite sides of the fan blades and motor along the air supply direction of the flow channel 1021, and both support structures 10 are equipped with wet curtains 13. During the operation of the air supply device 100, the moisture in the wet curtains 13 located on the air inlet side of the flow channel 1021 will be blown towards the fan blades and motor under the action of airflow, which can easily cause the motor and other circuit equipment to come into contact with water and short circuit, posing a significant safety hazard.

[0073] Based on this, this application adds a second baffle 1018 to block the airflow and moisture blowing towards the motor, thereby preventing the motor and other circuit equipment from short-circuiting due to water contact, and effectively improving the safety performance of the air supply device 100.

[0074] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0075] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
