DETAILED DESCRIPTION

[0021] The present application will be further described in detail below in combination with the drawings and the specific embodiments.

[0022] Referring to the drawings, the embodiment provides a spray head 10 for the corridor dust reduction, which comprises a water pipe connector 100, a water mist supply pipe 200, a gear adjusting device 500, a nozzle unit 300 and a valve seat 400. Figure 1 Figure 2

[0023] ​​One end of the water pipe connector 100 is connected with the external water pipe 20, and the other end of the water pipe connector 100 is connected with one end of the water mist supply pipe 200, and the one end of the water mist supply pipe 200 is connected on the outer surface of the other end of the water pipe connector 100, and the one end of the water mist supply pipe 200 is rotatably connected on the other end of the water pipe connector 100.

[0024] Referring to the drawings Figure 2 and the drawings Figure 4 As shown in the drawings, a plurality of spray holes 201 are arranged on the outer surface of the other end of the water mist supply pipe 200 in the circumferential direction, and the gear adjusting device 500 is fixedly installed on the outer surface of the water mist supply pipe 200, and the function of the gear adjusting device 500 is to drive the water mist supply pipe 200 to rotate in the circumferential direction.

[0025] Referring to the drawings Figure 2 As shown in the drawings, specifically, the gear adjusting device 500 includes a cylindrical mounting seat 501, and the mounting seat 501 is internally formed with a cavity, and an internal threaded connection part is formed on the inner wall of the mounting seat 501. Correspondingly, an external threaded connection part is formed on the outer surface of the water mist supply pipe 200 in the circumferential direction, so that the mounting seat 501 can be fixedly installed on the water mist supply pipe 200 through the threaded cooperation between the internal threaded connection part and the external threaded connection part. In this way, when it is necessary to adjust the water output, the mounting seat 501 can be conveniently rotated to synchronously drive the water mist supply pipe 200 to rotate, thereby conveniently adjusting the water output.

[0026] Referring to the drawings Figure 2 As shown in the drawings, in order to ensure that the water mist supply pipe 200 cannot easily rotate by itself, the locking device 600 is further arranged on the mounting seat 501, and the locking device 600 includes a locking screw 602 and a screw hole 601 opened on the mounting seat 501, and the locking screw 602 is installed in the screw hole 601. After the rotation adjustment of the water mist supply pipe 200 is completed, the locking screw 602 is rotated to make the bottom end of the locking screw 602 abut against the outer surface of the water mist supply pipe 200, thereby locking the water mist supply pipe 200 to prevent the water mist supply pipe 200 from rotating. When it is necessary to rotate the water mist supply pipe 200, the locking screw 602 is reversely rotated to make the bottom end of the locking screw 602 away from the outer surface of the water mist supply pipe 200, thereby unlocking the water mist supply pipe 200.

[0027] Continuing to refer to the drawings Figure 2As shown, the nozzle unit 300 comprises a nozzle shell 301 and a plurality of rotating bodies 302, the nozzle shell 301 is rotationally mounted on the outer surface of the mounting seat 501, a plurality of mounting holes are formed on the end surface of the nozzle shell 301 away from the water pipe connector 100 in the circumferential direction, and the rotating bodies 302 are rotationally mounted in the mounting holes in correspondence, and the outer surface of the rotating body 302 is formed with a helical groove 303 in the axial direction thereof.

[0028] The valve seat 400 comprises a valve seat shell 401 and a valve pipe 403, the outer surface of the valve pipe 403 is provided with a plurality of communication holes 402 in the circumferential direction, the valve seat shell 401 is mounted on the nozzle shell 301 at the end surface of the mounting hole, one end of the valve pipe 403 is fixedly mounted on the valve seat shell 401, the valve pipe 403 is mounted in the inner cavity of the water mist supply pipe 200, and the valve seat shell is fixedly mounted on the nozzle shell 301, the communication hole 402 and the spray hole 201 are located at the same radial position, and the water in the water mist supply pipe 200 can enter the helical groove through the communication hole 402 and the spray hole 201 and be sprayed outwards.

[0029] In order to ensure that the external water source can smoothly enter the nozzle unit 300 from the communication hole 402 in the valve pipe 403, the opening size of the communication hole 402 is greater than the opening size of the spray hole 201, for example, the opening size of the communication hole 402 is 1.5 to 2 times the opening size of the spray hole 201.

[0030] Referring to the accompanying drawings Figure 2 to the accompanying drawings Figure 6 As shown, in order to better understand the spray head for reducing dust in the corridor in the embodiment, the working principle thereof is briefly described as follows:

[0031] Referring to the accompanying drawings Figure 2 , the accompanying drawings Figure 4 and the accompanying drawings Figure 6As shown, in this embodiment, the sprinkler head 10 is installed in the area above the stairwell and is connected to an external water source via a water pipe connector 100. During spray cleaning operations (e.g., at night), the operator turns on the external water source. The external water source enters the water mist supply pipe 200 through the water pipe connector 100. The water flowing into the water mist supply pipe 200 then enters the inner cavity of the valve pipe 403. The water flowing into the inner cavity of the valve pipe 403 enters the spray hole 201 in the water mist supply pipe 200 through the connecting hole 402, and then enters the inner cavity of the nozzle housing 301 from the spray hole 201. Finally, it enters the spiral groove 303 on the rotating body 302. The water flows outward from the spiral groove 303 on the outer surface of the rotating body 302. When the water source flows through the spiral groove 303, it exerts a force on the rotating body 302, causing the rotating body 302 to rotate. This causes the sprayed water to be sprayed evenly in a circumferential direction, which has a dust reduction effect on the stairwell area below. This avoids the need for manual cleaning of the stairwell, and the cleaning method using this type of spray head is also more cost-effective. Furthermore, the water output in this embodiment can be flexibly adjusted. Specifically, the water mist supply pipe 200 can be rotated via the gear adjustment device 500, changing the size of the communication area between the spray hole 201 and the connecting hole 402, thereby altering the flow rate of the water source. Additionally, the spray hole 201 can be closed within the water mist supply pipe 200 (see attached diagram). Figure 3 and attached Figure 5 As shown in the figure, when there is no overlapping area between the spray hole 201 and the connecting hole 402, the water cannot enter the spiral groove 303 and spray outward, thus achieving the closure of the spray head.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
