Description

Technical Field

[0001] The present invention relates to the technical field of fans, and particularly to a fan structure and a fan. Background Art

[0002] With the continuous improvement of living standards, users' requirements for fans are also getting higher and higher. The cold fan can bring better comfort to users, so it is very popular among users.

[0003] Traditional cold fans generally come with a corresponding water distribution box to supply water to the wet curtain. As a type of cold fan, the tower cold fan is generally provided with a wet curtain assembly. When the tower cold fan is in the humidification state, it will drive the wet curtain assembly to rotate up and down and shake its head. When the wet curtain rotates to an inclined or horizontal direction, with the traditional water distribution box, water is likely to spill out of the water distribution box, affecting the safety of the components inside the tower cold fan. Summary of the Invention

[0004] Based on this, in view of the problem that when the tower cold fan is in use, water is likely to spill out of the water distribution box, affecting the safety of the components inside the tower cold fan, a fan structure and a cold fan are proposed. When the fan structure and the cold fan are in use, water will not spill out of the water distribution member, and the safety of the components inside the cold fan will not be affected.

[0005] The specific technical solutions are as follows:

[0006] On the one hand, the present application relates to a fan structure, including a wet curtain assembly and a water distribution member. The water distribution member is connected to the wet curtain assembly. The water distribution member is provided with a sealed channel, an inlet and an outlet communicating with the sealed channel. The water distribution member supplies water to the wet curtain assembly through the outlet.

[0007] The technical solutions are further described below:

[0008] In one embodiment, the water distribution member is tubular, and the water distribution member is arranged with both ends sealed and the inlet and the outlet are provided in the middle.

[0009] In one embodiment, both ends of the water distribution member are sealed by rubber plugs.

[0010] In one embodiment, the number of outlets is multiple, and all the outlets are arranged at intervals along the length direction of the water distribution member.

[0011] In one embodiment, the wet curtain assembly includes a wet curtain and a first water receiving member. The first water receiving member is connected to the wet curtain and faces the air inlet surface of the wet curtain to receive the water dripping along the air inlet surface of the wet curtain.

[0012] In one embodiment, the first water receiving member includes at least two water receiving portions spaced apart in the thickness direction of the first water receiving member. Each water receiving portion is provided with a first water receiving groove, and the first water receiving grooves in adjacent two water receiving portions are arranged in a staggered manner.

[0013] In one embodiment, the fan structure further includes a second water receiving member. The second water receiving member is engaged and cooperated with the water outlet end of the wet curtain for receiving the water discharged from the water outlet end of the wet curtain, and the first water receiving groove is communicated with the second water receiving member.

[0014] In one embodiment, the first water receiving member includes a first water receiving body and a second water receiving body. The first water receiving body is connected to the wet curtain, and the second water receiving body is rotatably connected to the first water receiving body. The first water receiving body is provided with a second water receiving groove, and the second water receiving body is provided with a third water receiving groove;

[0015] When the second water receiving body rotates relative to the first water receiving body to overlap with the first water receiving body, the second water receiving groove and the third water receiving groove are spaced apart in the thickness direction of the first water receiving member, and the second water receiving groove and the third water receiving groove are staggered to receive the water dripping from the air inlet surface of the wet curtain.

[0016] In one embodiment, the number of the second water receiving grooves is at least two. The two second water receiving grooves are spaced apart to form a first air inlet gap. When the second water receiving body rotates relative to the first water receiving body to overlap with the first water receiving body, the water inlet of the third water receiving groove completely covers the first air inlet gap along the orthographic projection of the first water receiving body; or

[0017] The spaced arrangement of the second water receiving grooves and the spaced arrangement of the second water receiving grooves and the edge of the first water receiving body both form a first air inlet gap. The number of the third water receiving grooves is at least two. The two third water receiving grooves are spaced apart. When the second water receiving body rotates relative to the first water receiving body to overlap with the first water receiving body, the water inlet of one third water receiving groove completely covers one first air inlet gap along the orthographic projection of the first water receiving body.

[0018] On the other hand, the present application further relates to a fan, including the fan structure in any of the above embodiments, and further including a fan and a support rod. The fan and the wet curtain assembly are both rotatably connected to the support rod.

[0019] When the above-mentioned fan structure and the fan including the fan structure are in use, water is supplied to the water inlet end of the wet curtain assembly through the water distributor. Since the sealing channel inside the water distributor is sealed, water can only be discharged along the water outlet to the water inlet end of the wet curtain assembly. When the wet curtain assembly rotates, there is no relative movement between the wet curtain assembly and the water distributor, and the wet curtain assembly will drive the water distributor to rotate together. Therefore, the water distributor will not sprinkle water onto other parts and will not cause damage to the components inside the fan. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0042] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0043] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0044] Please refer to Figures 1 to 4 , a fan (not shown) in an embodiment includes a blower 40, a support rod 30, and a fan structure (not shown). The fan structure includes a wet curtain assembly 10. Both the blower 40 and the wet curtain assembly 10 are rotatably connected to the support rod 30.

[0045] Please refer to Figure 4 , the fan structure further includes a water distributor 20. The water distributor 20 is connected to the wet curtain assembly 10. The water distributor 20 is provided with a sealed channel (not shown), a water inlet 800 and a water outlet 700 communicating with the sealed channel. The water distributor 20 supplies water to the wet curtain assembly 10 through the water outlet 700.

[0046] Please refer to Figures 1 to 4 , when the above-mentioned fan structure and the fan including the fan structure are in use, water is supplied to the water inlet end of the wet curtain assembly 10 through the water distributor 20. Since the sealed channel inside the water distributor 20 is sealed, the water can only be discharged to the wet curtain assembly 10 along the water outlet 700. When the wet curtain assembly 10 rotates, the wet curtain assembly 10 and the water distributor 20 do not move relative to each other, and the wet curtain assembly 10 drives the water distributor 20 to rotate together. Therefore, the water distributor 20 will not sprinkle water to other parts and will not cause damage to the components inside the fan.

[0047] Please refer to Figure 5In one embodiment, the water distribution member 20 includes multiple water outlets 700 spaced apart along the length of the water distribution member 20. Water enters the sealed channel through the water inlet 800 and is distributed according to a predetermined ratio and discharged through each water outlet 700. Specifically, the water distribution member 20 can evenly distribute the water and discharge it through each water outlet 700 toward the wet curtain assembly 10.

[0048] Please refer to Figure 5 The water distribution member 20 is tubular, sealed at both ends and equipped with a water inlet 800 and a water outlet 700 in the middle. This tubular shape helps increase the pressure within the sealed channel. When the wet curtain assembly 10 rotates to a horizontal position, water can be sprayed from the water outlet 700 to the water inlet of the wet curtain assembly 10. Specifically, the water distribution member 20 is sealed at both ends with rubber plugs.

[0049] When the wet curtain assembly 10 is rotating, there is a risk that the water on the wet curtain assembly 10 will enter the interior of the machine body. Figure 3 Specifically, in one embodiment, the wet curtain assembly 10 includes a wet curtain 100 and a first water receiving member 200. The first water receiving member 200 is connected to the wet curtain 100 and faces the air inlet surface 130 of the wet curtain to receive water dripping along the air inlet surface 130 of the wet curtain. When the wet curtain assembly 10 rotates, the wet curtain 100 rotates with the first water receiving member 200. When the wet curtain assembly 10 rotates to a certain angle, water dripping along the air inlet surface 130 of the wet curtain is likely to be received by the first water receiving member 200, thereby reducing the risk of water dripping from the wet curtain assembly 10 into the interior of the machine and improving user safety.

[0050] Please refer to Figure 3 In one embodiment, the first water receiving member 200 includes at least two layers of water receiving portions 210 spaced apart in the thickness direction of the first water receiving member 200, each layer of the water receiving portion 210 is provided with a first water receiving groove 212, and the first water receiving grooves 212 in two adjacent layers of the water receiving portion 210 are staggered. Figure 3 The thickness direction of the wet curtain 100 is the L direction in the figure.

[0051] Please refer to Figures 1 to 3When the wet curtain assembly 10 and the fan including the wet curtain assembly 10 in the aforementioned embodiment are in use, when the wet curtain assembly 10 rotates, the wet curtain 100 rotates together with the first water receiving member 200; when rotated to a certain angle, water on the wet curtain 100 drips along the air inlet surface 130 of the wet curtain and just falls into the water receiving portion 210; since the first water receiving member 200 includes at least two layers of water receiving portions 210 spaced apart in the thickness direction of the first water receiving member 200, each layer of water receiving portion 210 is provided with a first water receiving groove 212, and the first water receiving grooves 212 of the two adjacent layers of water receiving portions 210 are staggered. Therefore, the water discharged along the air inlet surface 130 of the wet curtain is highly likely to be received by the first water receiving groove 212 of one layer of the water receiving portion 210, thereby reducing the risk of water on the wet curtain assembly 10 dripping into the interior of the machine body and improving the safety of use.

[0052] Specifically, the number of the first water receiving troughs 212 in each layer can be 2 or more, and the first water receiving troughs 212 of each layer are arranged at intervals. It is understandable that the specific number of the first water receiving troughs 212 in each layer can be set according to the specific size of the wet curtain 100.

[0053] Optionally, the first water receiving trough 212 may be V-shaped or U-shaped.

[0054] Please refer to Figure 3 and Figure 8 In this embodiment, the first water receiving member 200 includes two layers of water receiving portions 210. By providing the two layers of water receiving portions 210, the risk of water dripping into the interior of the fuselage is reduced, thereby improving the safety of use.

[0055] In other embodiments, the number of layers of the water receiving part 210 can be 3 layers or more, all the water receiving parts 210 are arranged at intervals along the thickness direction of the first water receiving part 200, and each layer of the water receiving part 210 is provided with a first water receiving groove 212, and the first water receiving grooves 212 in two adjacent layers of the water receiving parts 210 are staggered. Therefore, the water discharged along the air inlet surface 130 of the wet curtain is likely to be received by the first water receiving groove 212 of one layer of the water receiving part 210, thereby reducing the risk of water on the wet curtain assembly 10 dripping into the interior of the fuselage and improving the safety of use.

[0056] Please refer to Figure 2 The wet curtain 100 includes a wet curtain body 110 and a mounting bracket 120 . The mounting bracket 120 forms a mounting cavity 122 . The wet curtain body 110 is disposed in the mounting cavity 122 . The first water receiving member 200 is connected to the mounting bracket 120 .

[0057] Please refer to Figure 1 and Figure 2, in one embodiment, the wet curtain assembly 10 further includes a limiting member 500. The limiting member 500 is connected to the mounting bracket 120 and is in limiting cooperation with the wet curtain body 110 to limit and install the wet curtain body 110 in the installation cavity 122. In this way, the limiting cooperation between the limiting member 500 and the wet curtain body 110 restricts the wet curtain body 110 from falling off from the installation cavity 122.

[0058] Please refer to Figure 1 and Figure 2 , the shape of the installation cavity 122 is set to a U shape. At this time, in order to fit and install in the installation cavity 122, the shape of the wet curtain body 110 is also set to a U shape.

[0059] Specifically, in one embodiment, the mounting bracket 120 and the limiting member 500 are snap-connected. In this way, it is convenient for the disassembly and assembly between the mounting bracket 120 and the limiting member 500.

[0060] Optionally, in one embodiment, one of the mounting bracket 120 and the limiting member 500 is provided with a card hole 126, and the other forms a card convex 510. The mounting bracket 120 and the limiting member 500 are snap-connected through the card hole 126 and the card convex 510.

[0061] Please refer to Figure 1 and Figure 7 , in this embodiment, the mounting bracket 120 is provided with a buckle, and the limiting member 500 is provided with a card convex 510. The mounting bracket 120 and the limiting member 500 are snap-connected through the card hole 126 and the card convex 510.

[0062] In other embodiments, the mounting bracket 120 and the limiting member 500 can be connected by screws, or the mounting bracket 120 and the limiting member 500 can be fixed by other fasteners. Of course, in other embodiments, other fastening methods can also be used to fix the two, as long as the limiting member 500 limits and installs the wet curtain body 110 in the installation cavity 122, which will not be elaborated here one by one.

[0063] Please refer to Figure 1 , the mounting bracket 120 can be in a mesh structure. In other embodiments, the mounting bracket 120 can also be a mounting rod or a mounting block.

[0064] Please refer to Figure 2 , the mounting bracket 120 is provided with a drain port 128 communicating with the installation cavity 122. When the wet curtain body 110 is installed in the installation cavity 122, the water outlet end of the wet curtain 100 is communicated with the second water receiving member 300 through the drain port 128. In this way, the water along the water outlet end of the wet curtain 100 can be discharged to the second water receiving member 300 through the drain port 128, and the second water receiving member 300 receives the water, and then the second water receiving member 300 conveys the water to a water tank (not shown) for reuse.

[0065] Please refer to Figure 5 , the water distribution member 20 is connected to the mounting bracket 120, and the water distribution member 20 is used to supply water to the water inlet end of the wet curtain 100.

[0066] Please refer to Figure 1 and Figure 2 , in one embodiment, the wet curtain assembly 10 further includes a second water receiving member 300. The second water receiving member 300 is engaged with the water outlet end of the wet curtain 100 for receiving the water discharged along the water outlet end of the wet curtain 100. After the water entering from the water inlet end of the wet curtain 100 is transmitted on the wet curtain 100, it will be discharged along the water outlet end of the wet curtain 100 and received by the second water receiving member 300. Please refer to Figure 1 exchange and Figure 2 , the second water receiving member 300 is connected to the mounting bracket 120.

[0067] Optionally, the second water receiving member 300 can be a water receiving box.

[0068] In one embodiment, the first water receiving member 200 and the second water receiving member 300 are communicated. Specifically, the first water receiving groove 212 is communicated with the second water receiving member 300. In this way, the water received by the first water receiving member 200 can be discharged to the second water receiving member 300. Further, the second water receiving member 300 can be communicated with the water tank of the cooling fan. In this way, the water in the second water receiving member 300 can flow back into the water tank for reuse.

[0069] Please refer to Figure 2 , the first water receiving groove 212 is arranged to extend along the direction from the water inlet end of the wet curtain 100 to the water outlet end of the wet curtain 100. In order to facilitate the second water receiving member 300 to receive the water in the first water receiving groove 212 in the first water receiving member 200, corresponding through holes can also be opened at the end of the first water receiving member 200, so that the first water receiving groove 212 can directly discharge the water onto the second water receiving member 300. In other embodiments, the second water receiving member 300 can also cover the end of the first water receiving member 200. When the first water receiving member 200 rotates with the wet curtain assembly 10, the water directly overflows and is conveyed onto the second water receiving member 300.

[0070] When the wet curtain 100 rotates up and down, the water on the wet curtain 100 will directly hit the first water receiving member 200, causing the water on the first water receiving member 200 to splash. Based on this, please refer to Figure 2 , in one embodiment, the wet curtain assembly 10 further includes a filter member 600. The filter member 600 is arranged between the air inlet surface 130 of the wet curtain and the first water receiving member 200. In this way, the setting of the filter member 600 can play a certain role in blocking the water dripping along the wet curtain 100, and thus can prevent the water from directly falling onto the first water receiving member 200.

[0071] Optionally, the filter member 600 can be a filter net. It should be noted that there is a second air inlet gap 2122 between two adjacent water receiving parts 210. Air enters along this second air inlet gap 2122, passes through the filter member 600 and reaches the wet curtain 100. Therefore, by arranging the filter member 600 between the first water receiving member 200 and the wet curtain 100, the filter member 600 can play a role in dust prevention, avoiding dust being blown towards the wet curtain 100 by the wind and polluting the wet curtain 100.

[0072] It can be understood that although a second air inlet gap 2122 is formed between the first water receiving grooves 212 in two adjacent layers, this second air inlet gap 2122 is small enough to only allow air flow. Therefore, when the fan is in use, the influence of the water dripping along the wet curtain 100 entering the fuselage interior along the second air inlet gap 2122 on the fuselage can be completely ignored.

[0073] In one embodiment, the shape of the filter member 600 matches the shape of the first water receiving member 200, so as to ensure that the water flowing out along the wet curtain 100 will not directly fall into the first water receiving member 200.

[0074] Please refer to Figure 15 and Figure 16 , in one embodiment, the filter member 600 and the first water receiving member 200 are both U-shaped. Of course, in other embodiments, the filter member 600 and the first water receiving member 200 can also be square or other shapes, which will not be elaborated here one by one.

[0075] Please refer to Figure 3 and Figure 6 , in one embodiment, the mounting bracket 120 is provided with a receiving groove 124, and both the first water receiving member 200 and the filter member 600 are inserted into the receiving groove 124. In this way, it is convenient to install the first water receiving member 200 and the filter member 600 on the mounting bracket 120, and it is also convenient to disassemble.

[0076] Furthermore, in order to fix the first water receiving member 200 and the filter member 600, the total thickness of the parts of the filter member 600 and the first water receiving member 200 extending into the receiving groove 124 can be set to be equal to or slightly greater than the width of the receiving groove 124. In this way, the filter member 600 and the first water receiving member 200 can be fixed more firmly in the receiving groove 124.

[0077] Please refer to Figure 2 and Figure 6 , in this embodiment, a plugging protrusion 220 is formed at the edge of the first water receiving member 200, and the first water receiving member 200 is in plugging fit with the receiving groove 124 through this plugging protrusion 220.

[0078] When the fan in the foregoing embodiment is assembled, both the filter element 600 and the first water receiving member 200 extend into the receiving groove 124 on the mounting bracket 120 for limit installation, so that both the filter element 600 and the first water receiving member 200 are tightly fastened to the mounting bracket 120. Then, the wet curtain 100 is installed into the installation cavity 122 of the mounting bracket 120, and the limiting member 500 is used to engage with the mounting bracket 120 to prevent the wet curtain 100 from coming out. Finally, the second water receiving member 300 is installed at the lower end of the mounting bracket 120 for receiving the water discharged from the water outlet end of the wet curtain 100 and the first water receiving member 200. When the fan (not shown) is in use, the water is evenly distributed to the wet curtain 100 through the water distribution member 20. When the wet curtain assembly 10 swings up and down, the already wet wet curtain 100 will start to drip water. At this time, the first water receiving member 200 and the filter element 600 will catch the water dripping from the wet curtain 100, so that the water dripping from the wet curtain 100 will flow along the first water receiving groove 212 on the first water receiving member 200 to the second water receiving member 300 and then fall back into the water tank for repeated use.

[0079] Please refer to Figures 9 to 12 , in another embodiment, the first water receiving member 200 includes a first water receiving body 230 and a second water receiving body 240. The first water receiving body 230 is connected to the wet curtain 100. Specifically, the first water receiving body 230 is connected to the mounting bracket 120. The second water receiving body 240 is rotatably connected to the first water receiving body 230. The first water receiving body 230 is provided with a second water receiving groove 232, and the second water receiving body 240 is provided with a third water receiving groove 242; when the second water receiving body 240 rotates relative to the first water receiving body 230 to overlap with the first water receiving body 230, the second water receiving groove 232 and the third water receiving groove 242 are arranged at intervals along the thickness direction of the first water receiving member 200, and the second water receiving groove 232 and the third water receiving groove 242 are offset to receive the water dripping from the air inlet surface 130 of the wet curtain.

[0080] Please refer to Figures 9 to 12 , when the wet curtain assembly 10 and the fan including the wet curtain assembly 10 are in use, when the wet curtain assembly 10 rotates, the wet curtain 100 will rotate together with the first water receiving member 200; when rotating to a certain angle, due to the offset arrangement of the second water receiving groove 232 and the third water receiving groove 242, the water falling along the air inlet surface 130 of the wet curtain will probably be received by the second water receiving groove 232 or the third water receiving groove 242 at this time, thereby reducing the risk of water droplets on the wet curtain assembly 10 falling into the fuselage interior and improving the use safety. Further, since the first water receiving body 230 and the second water receiving body 240 are rotatably connected, compared with the integrally formed structure of the first water receiving body 230 and the second water receiving body 240, the second water receiving groove 232 in the first water receiving body 230 and the third water receiving groove 242 in the second water receiving body 240 are convenient for mold release.

[0081] Since the fan draws in air along this side of the first water receiving member 200 during use, in order to enable the air to be delivered to the wet curtain 100 through this side of the first water receiving member 200, a first air inlet gap 2322 needs to be formed between the edge of the second water receiving groove 232 and the first water receiving body 230. Or when there are at least two second water receiving grooves 232, the spaced arrangement of the second water receiving grooves 232 and the spaced arrangement of the second water receiving grooves 232 and the edge of the first water receiving body 230 both form the first air inlet gap 2322.

[0082] In order to prevent water from dripping into the body interior along the first air inlet gap 2322, in one embodiment, when only the first air inlet gap 2322 is formed between the second water receiving grooves 232, when the second water receiving body 240 rotates relative to the first water receiving body 230 to overlap with the first water receiving body 230, the water inlet of the third water receiving groove 242 completely covers the first air inlet gap 2322 in the orthographic projection along the first water receiving body 230. At this time, the third water receiving groove 242 located in the second water receiving body 240 will collect the water dripping along the first air inlet gap 2322, thereby preventing water droplets from dripping into the body interior along the aforementioned first air inlet gap 2322 and damaging the components inside the body.

[0083] In other embodiments, the spaced arrangement of the second water receiving grooves 232 and the spaced arrangement of the second water receiving grooves 232 and the edge of the first water receiving body 230 both form the first air inlet gap 2322. At this time, the number of the second water receiving grooves 232 is at least two, and the two second water receiving grooves 232 are spaced apart. When the second water receiving body 240 rotates relative to the first water receiving body 230 to overlap with the first water receiving body 230, the water inlet of one third water receiving groove 242 completely covers one first air inlet gap 2322 in the orthographic projection along the first water receiving body 230. At this time, the third water receiving groove 242 located in the second water receiving body 240 will collect the water dripping along the first air inlet gap 2322, thereby preventing water droplets from dripping into the body interior along the aforementioned first air inlet gap 2322 and damaging the components inside the body.

[0084] In the above two parallel embodiments, the number of the second water receiving grooves 232 and the third water receiving grooves 242 can both be set to at least two. When the second water receiving body 240 rotates relative to the first water receiving body 230 to overlap with the first water receiving body 230, the second water receiving grooves 232 and the third water receiving grooves 242 are spaced apart along the thickness direction of the first water receiving member 200, and the second water receiving grooves 232 are spaced apart, and the third water receiving grooves 242 are spaced apart. In this way, it is possible to ensure that the water dripping from the wet curtain 100 is collected and also ensure that the air flow can be delivered to the wet curtain 100 along this first water receiving member 200.

[0085] Please refer to Figure 13 and Figure 14, in one embodiment, the wet curtain assembly 10 further includes a third water receiving member 400, and the third water receiving member 400 is connected and cooperated with the water outlet end of the wet curtain 100 to receive the water discharged along the water outlet end of the wet curtain 100. After the water entering along the water inlet end of the wet curtain 100 is transmitted on the wet curtain 100, it will be discharged along the water outlet end of the wet curtain 100 and received by the third water receiving member 400. Please refer to Figure 13 and Figure 14 , the third water receiving member 400 is connected to the mounting bracket 120.

[0086] Please refer to Figure 13 and Figure 14 , in one embodiment, the third water receiving member 400 is provided with a receiving cavity 410. When the second water receiving body 240 rotates relative to the first water receiving body 230 to overlap with the first water receiving body 230, the third water receiving member 400 is sleeved on the water outlet end of the wet curtain 100 through the receiving cavity 410, and the inner wall of the receiving cavity 410 cooperates with the outer wall of the wet curtain 100 to clamp and fix the second water receiving body 240 and the first water receiving body 230 between the inner wall of the receiving cavity 410 and the outer wall of the wet curtain 100.

[0087] During installation, first fix the first water receiving body 230 on the mounting bracket 120. In one embodiment, the mounting bracket 120 is provided with a limiting groove (not shown), and the first water receiving body 230 is inserted into the limiting groove. Then rotate the second water receiving body 240 to make the second water receiving body 240 overlap with the first water receiving body 230. At this time, the third water receiving member 400 is sleeved on the water outlet end of the wet curtain 100 through the receiving cavity 410, and the inner wall of the receiving cavity 410 cooperates with the outer wall of the wet curtain 100 to clamp and fix the second water receiving body 240 and the first water receiving body 230 between the inner wall of the receiving cavity 410 and the outer wall of the wet curtain 100.
