The nozzle assembly 100 includes a spray head 101 and a fixed pipe 102, and the spray head 101 is rotatably coupled to one end of the fixed pipe 102. The water inlet assembly 200 comprises a water inlet pipe 201 and a first connecting pipe 202, wherein one end of the first connecting pipe 202 is connected with the water inlet pipe 201, and the other end of the first connecting pipe 202 is connected with one end of the fixed pipe 102 far away from the spray head 101. With the above arrangement, the water inlet assembly 200 provides a water source, and the nozzle assembly 100 sprays water onto the filter cloth through the rotatable spray head 101.

Further, one end of the nozzle 101 is provided with a plurality of nozzles 101a, the other end of the nozzle 101 is provided with a rotating spherical cavity 101b, one end of the fixed pipe 102 is provided with a fixed spherical cavity 102a, the other end of the fixed pipe 102 is provided with a water inlet channel 102b, the water inlet channel 102b extends to the fixed spherical cavity 102a, and the rotating spherical cavity 101b and the fixed spherical cavity 102a are concentrically arranged. The fixed spherical cavity 102a is composed of two identical hemispheres, and is formed by connecting through bolts.

Further, the top of the fixed spherical cavity 102a forms a first opening 102a-1, and the diameter of the first opening 102a-1 is smaller than the diameter of the central section of the fixed spherical cavity 102a, so as to ensure that the rotating spherical cavity 101b is clamped in the fixed spherical cavity 102 a.

Further, the bottom of the rotary spherical cavity 101b is formed with a second opening 101b-1, the diameter of the second opening 101b-1 is smaller than the diameter of the central section of the rotary spherical cavity 101b, and the diameter of the water inlet passage 102b is smaller than the diameter of the second opening 101 b-1. The above arrangement ensures that the spray head 101 is free to rotate within the fixed pipe 102 through an angle of about 60.

Further, a positioning ring 102a-2 is disposed at one end of the fixed spherical cavity 102a close to the water inlet channel 102 b. The retaining ring may limit the rotational angle of the showerhead 101.

Further, the inner wall of the fixed spherical cavity 102a is provided with a gasket 102 a-3. The seal 102a-3 provides good sealing performance against water leakage at the rotating location.

Further, the end of the head 101 provided with the nozzle 101a is spherical. The spherical design can make the spray range of the spray head 101 larger.

Example 2

Referring to fig. 5, a second embodiment of the present invention is based on the previous embodiment, and specifically, further includes an air intake assembly 300. The air inlet assembly 300 comprises an air inlet pipe 301, a second connecting pipe 302 and an air inlet joint 303, wherein one end of the second connecting pipe 302 is connected with the air inlet pipe 301, the other end of the second connecting pipe 302 is connected with the air inlet joint 303, and one end, far away from the second connecting pipe 302, of the air inlet joint 303 is connected with the fixed pipe 102. High-pressure gas is introduced into the gas inlet pipe 301 and finally into the spray head 101, so that the water pressure is increased.

Further, an air inlet hole 303a is formed in the air inlet joint 303, a sealing member 304 is disposed on a side of the air inlet hole 303a close to the fixed pipe 102, and the sealing member 304 is connected to an inner wall of the fixed pipe 102 by a torsion spring 305. The sealing member 304 has two pieces which are combined to form a spherical shape just to block the air intake holes 303 a. When high-pressure gas is not introduced into the air inlet joint 303, the elastic potential energy of the torsion spring 305 enables the sealing member 304 to just block the air inlet hole 303a, so that the purpose of preventing water backflow is achieved. When high pressure gas is introduced into the inlet fitting 303, the gas pressure causes the seal 304 to move away from the inlet hole 303 a.

An air inlet check valve 306 is arranged at one end of the air inlet joint 303 far away from the fixed pipe 102, an adjustable throttle valve 307 is arranged on the side surface of the air inlet joint 303, and the second connecting pipe 302 is connected with the air inlet joint 303 through the air inlet check valve 306.

The working principle is as follows: water and high-pressure gas are respectively introduced into the water inlet pipe 201 and the air inlet pipe 301, the water is sprayed out from the spray head 101, and the spray head 101 is enabled to spray the water at a proper spraying angle by adjusting the angle between the spray head 101 and the fixed pipe 102. The pressure of the high-pressure gas is adjusted through the adjustable throttle valve 307, so that the spraying strength of the water flow is adjusted.
