[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] See Figures 1 to 6 This utility model discloses a hanging spray assembly, comprising: an annular mounting base 100, a plurality of nozzles 200 provided on the front side of the mounting base 100, the nozzles 200 being connected to a water supply pipe 710, and at least two mounting components 300 spaced circumferentially around the center of the mounting base 100 on the back side, the mounting components 300 including a mounting plate 310 and an elastic groove 320 formed on the mounting plate 310, the mounting plate 310 being rotatably connected to the mounting base 100 via a rotating shaft 400 perpendicular to the back side of the mounting base 100, and the elastic groove 320 being used to engage with the metal strip 11 of the mesh cover of the fan 10.

[0032] It should be noted that the metal strips 11 of the fan 10's mesh cover come in various specifications. Generally, they have multiple radially distributed metal pillars and multiple concentrically arranged metal rings that increase in size from the inside out. The hanging spray assembly with the above structure uses the hollowed-out position of the annular mounting base 100 to avoid airflow to the center position of the fan 10's mesh cover. The elastic slot 320 on the mounting component 300 can be used to engage with the metal pillars or metal rings of the fan 10's mesh cover. The angle and position of the elastic slot 320 can be adjusted by rotating the mounting plate 310 relative to the mounting base 100 to adapt to different shapes and specifications of fan 10 mesh covers. Moreover, the installation is convenient, thus improving the ease of use.

[0033] See Figure 1 In some embodiments of this utility model, the mounting base 100 is annular, and the plurality of nozzles 200 are evenly distributed circumferentially around the center of the mounting base 100. Specifically, the annular shape of the mounting base 100 and the arrangement of the plurality of nozzles 200 facilitate the uniform blowing of the water mist. Of course, in other embodiments, the mounting base 100 may also be rectangular, elliptical, or other shapes.

[0034] See Figure 3In some embodiments of this utility model, in order to facilitate the production and assembly of the hanging spray assembly of this utility model, the mounting base 100 includes an annular cover 110, the annular cover 110 has an annular cavity 111 with an opening facing backward, the annular cover 110 is provided with mounting holes 112 corresponding to the nozzles 200 one by one in the front-back direction, an annular end plate 120 is mounted on the annular cover 110 to close the opening of the annular cavity 111, the annular end plate 120 and the annular cover 110 define an annular cavity, a portion of the nozzles 200 is housed in the annular cavity, the output end of the nozzles 200 extends from the mounting hole 112 to outside the annular cover 110, and the mounting component 300 is provided on the annular end plate 120. During assembly, the nozzle 200 is passed through the mounting hole 112 so that the output end of the nozzle 200 extends out of the mounting hole 112, and the nozzle 200 is connected to the water supply pipe 710. Then, the nozzle 200 is protected by mounting the annular end plate 120 on the annular cover 110.

[0035] See Figure 3 and Figure 4 In some embodiments of this utility model, each nozzle 200 has a three-way valve 500. The three-way valve 500 has two relatively connected first input pipes 510 and a first output pipe 520 passing through the mounting hole 112. The first input pipes 510 are located within the annular cavity 111. The mounting base 100 is provided with a three-way valve 600 located between two of the nozzles 200. The three-way valve 600 has two relatively connected second output pipes 610 and a second input pipe 620 connected to the second output pipes 610. The second input pipe 620 is connected to the water supply pipeline 710. The second output pipe 610 is connected to the adjacent first input pipe 510 through a first pipe 720. The first input pipes 510 of the remaining three-way valves 500 are connected to each other through a second pipe 730. Understandably, water is input through the second input pipe 620 and output through two second output pipes 610. The water from the two second output pipes 610 then enters the first input pipe 510 of the corresponding three-way valve 500. Part of the water flows from the first output pipe 520 to the output end of the sprinkler head 200, while the rest flows from the other first input pipe 510 to the other three-way valve 500. This structure simplifies the connection between the sprinkler head 200 and the water supply pipe 710, and also allows for faster water supply.

[0036] See Figure 3 and Figure 4In some embodiments of this utility model, the annular cover 110 is provided with a limiting plate 113 located between adjacent outlet three-way valves 500. The limiting plate 113 is provided with a positioning groove 114 for engaging the first pipe 720 or the second pipe 730. Specifically, both the first pipe 720 and the second pipe 730 are made of flexible hoses. The positioning groove 114 can prevent the first pipe 720 and the second pipe 730 from tangling, shifting, or falling off.

[0037] See Figure 3 In some embodiments of this utility model, the limiting plate 113 is provided with a threaded sleeve 115 on one side of the positioning groove 114. The threaded sleeve 115, the limiting plate 113, and the annular cover 110 are an integral plastic structure. The rotating shaft 400 is a fastening bolt that passes through the mounting plate 310 and the annular end plate 120 and is threadedly connected to the threaded sleeve 115. It can be understood that the threaded sleeve 115 and the limiting plate 113 are injection molded together to provide structural reinforcement. The fastening bolt is used both to connect the annular cover 110 and the annular end plate 120 together and to provide rotational connection for the limiting plate 113, thus serving a dual purpose.

[0038] See Figure 2 and Figure 3 In some embodiments of this utility model, the mounting plate 310 is provided with an oblong hole 311 through which the rotating shaft 400 passes, and the length direction of the oblong hole 311 is arranged along the radial direction of the mounting base 100. It can be understood that when it is necessary to adjust the position of the elastic groove 320 along the radial direction of the mounting base 100, the rotating shaft 400 can be driven to move relative to the oblong hole 311, thereby adapting to more mounting positions.

[0039] See Figure 5 In some embodiments of this utility model, in order to prevent maintenance difficulties when the nozzle 200 becomes clogged, the nozzle 200 includes a nozzle 210 communicating with the first output pipe 520 and a nozzle 220 detachably connected to the nozzle 210.

[0040] See Figure 5In some embodiments of this utility model, the nozzle 220 is threadedly connected to the end of the spray pipe 210 away from the first output pipe 520. A sealing bead 230, a spring 240, and an atomizing nozzle 250 are sequentially arranged inside the spray pipe 210. One end of the spring 240 drives the sealing bead 230 to elastically abut against the internal channel of the spray pipe 210, and the other end of the spring 240 drives the atomizing nozzle 250 to elastically abut against the nozzle 220. A fluid gap communicating with the interior of the spray pipe 210 is provided between the atomizing nozzle 250 and the nozzle 220. It can be understood that when the sealing bead 230 and the spring 240 form a one-way valve, when fluid from the water supply pipe 710 enters the spray pipe 210, it pushes open the sealing bead 230, compresses the spring 240, and allows water to be sprayed outwards through the fluid gap.

[0041] See Figure 6 This utility model also discloses a fan 10, including the hanging spray assembly of any of the above-mentioned technical solutions. The fan 10 utilizes the hollowed-out position of the annular mounting base 100 to avoid airflow to the center position of the fan 10's mesh cover. The elastic slot 320 on the mounting component 300 is used to engage with the metal strip 11 of the fan 10's mesh cover. The mounting plate 310 rotates relative to the mounting base 100 to adjust the angle position of the elastic slot 320 to adapt to the mesh cover of the fan 10 with different shapes and specifications. Moreover, the installation is convenient, thereby improving the ease of use.

[0042] 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.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
