DETAILED DESCRIPTION

[0020] The following describes the implementation of the present invention in conjunction with the accompanying drawings and relevant embodiments. The implementation of the present invention is not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as common knowledge in this technical field and can be known and mastered by technical personnel in this technical field.

[0021] A nozzle of a pulse cleaning device includes a nozzle body, the nozzle body includes a first coupling body 3 and a second coupling body 4, the first coupling body 3 and the second coupling body 4 are tightly fitted together to form an independent jet impact area 1 5 and a jet impact area 2 6, the jet impact area 2 6 surrounds the jet impact area 1 5, the first coupling body 3 is connected to the outside at a position corresponding to the jet impact area 1 5 and the jet impact area 2 6, and the second coupling body 4 is connected to the inside of the device body at a position corresponding to the jet impact area 1 5 and the jet impact area 2 6, that is, connected to the water outlet 2

[0022] like Figures 1 to 5 As shown, in the structure of the cleaning device of the present invention, the cleaning device includes a water inlet 1 for hand holding and a water outlet 2 for emitting pulse jets, one end of the water outlet 2 is provided with the nozzle body, wherein one end of the water inlet 1 is connected to the water outlet 2, and the other end of the water inlet 1 is connected to the outside and is provided with a pulse pump, which controls the water flow by periodically opening and closing the pulse pump to generate pulses, and achieves the effect of controlling the intensity and frequency of the pulses by adjusting the frequency of opening and closing the pulse pump.

[0023] like Figure 3 and Figure 5 As shown, in the structure of the nozzle body of the present invention, the nozzle body includes a second coupling body 4 and a first coupling body 3 arranged in sequence from the inside to the outside along the end of the water outlet body 2, and the water outlet body 2 is composed of a first shell 201 and a second shell 202. The first shell 201 and the second shell 202 are fixed by screwing or at least one fixing method. The end of the first shell 201 facing the second shell 202 is clamped with the first coupling body 3 and the second coupling body 4. The inner wall of the first shell 201 is provided with an annular clamping groove 203 adapted to the outer surface of the first coupling body 3 and the second coupling body;

[0024] It should be noted that the annular snap-fit ​​groove 203 has an opening on one side facing the second shell 202. When in use, the second connecting body 4 and the first connecting body 3 are placed into the annular snap-fit ​​groove 203 along the opening position of the first shell 201 in sequence, and the annular snap-fit ​​groove 203 is closed by connecting and fixing the second shell 202 to the first shell 201. In the process of connecting and fixing the second shell 202 to the first shell 201, the second shell 202 simultaneously presses the first connecting body 3 onto the first connecting body 3, so that the first connecting body 3 and the second connecting body 4 are in a conflicting connection state.

[0025] like Figure 1 、 Figure 2 and Figure 3 As shown, in the structure of the first coupling body 3 and the second coupling body 4 of the present invention, the end surface of the first coupling body 3 facing the second coupling body 4 is provided with a first annular protrusion 301 and a second annular protrusion 302 in sequence from the inside to the outside, and the end surface of the second coupling body 4 facing the first coupling body 3 is provided with a first annular groove 401 and a second annular groove 402 in sequence from the inside to the outside, the first annular protrusion 301 is adapted to the first annular groove 401, and the second annular protrusion 302 is adapted to the second annular groove 402, and the first coupling body 3 and the second coupling body 4 are aligned and assembled to form a jet impact area 1 5 and a jet impact area 2 6;

[0026] Furthermore, in the above scheme, a first sealing ring 403 is provided at the bottom of the first annular groove 401, and the bottom end of the first annular protrusion 301 is inserted into the bottom of the first annular groove 401 and contacts the first sealing ring 403, thereby forming a jet impact area 5 in the middle of the first connecting body 3 and the second connecting body 4. The jet impact area 5 is aligned with the middle of the water outlet end of the water outlet body 2, which is the concentrated water outlet area of ​​the pulse jet. The jet enters the jet impact area 5 along the water inlet hole 406 and impacts the inner wall of the jet impact area 5, thereby realizing jet fragmentation and carrying relatively rich bubbles in the water flow.

[0027] Furthermore, in the above scheme, a second sealing ring 404 is provided at the bottom of the second annular groove 402, and the bottom end of the second annular protrusion 302 is inserted into the bottom of the second annular groove 402 and contacts the second sealing ring 404, thereby forming a jet impact zone 2 6 surrounding the outer edge of the jet impact zone 1 5 between the first connecting body 3 and the second connecting body. The jet impact zone 2 6 surrounds the outer edge of the jet impact zone 1 5 and is the water outlet edge area of ​​the pulse jet. The two sides of the jet impact zone 2 6 are respectively closed by the first annular protrusion 301 and the first annular groove 401, and the second annular protrusion 302 and the second annular groove 402, thereby forming the jet impact zone 2 6. The principle is the same as that of the jet impact zone 1 5. The jet enters the jet impact zone 2 6 through the water inlet hole 2 407 to achieve water flow fragmentation, thereby improving the cleaning effect.

[0028] Furthermore, in the above scheme, the first connector 3 is provided with a water outlet hole 1 303 passing through along the thickness direction at a position corresponding to the jet impact zone 1 5 , and the first connector 3 is provided with a water outlet hole 2 304 passing through along the thickness direction at a position corresponding to the jet impact zone 2 6 .

[0029] It should be noted that, in one embodiment, the jet impact zone 1 5 is the concentrated water outlet area of ​​the pulse jet, and the jet impact zone 2 6 is the water outlet edge area of ​​the pulse jet. Therefore, the number of water outlet holes 1 303 set in the first connector 3 corresponding to the jet impact zone 1 5 is greater than the number of water outlet holes 2 304 set in the jet impact zone 2 6. Furthermore, the aperture of the water outlet hole 1 303 is greater than or equal to the aperture of the water outlet hole 2 304.

[0030] In one embodiment of the present invention, a transition connector 7 is provided at the position of the first connector 3 and the second connector corresponding to the jet impact zone 1 5, and the two ends of the transition connector 7 are respectively in contact with the end surfaces of the first connector 3 and the second connector 4 facing each other. A third sealing ring 405 is provided at the position where the second connector 4 and the transition connector 7 are in contact, and the outer surface of the transition connector 7 is provided with a plurality of water outlet holes 701 provided along the thickness direction.

[0031] Furthermore, in the above solution, the second connector 4 is provided with a first water inlet hole 406 communicating with the interior of the device at a position corresponding to the first jet impact zone 5, and the second connector 4 is provided with a second water inlet hole 407 communicating with the interior of the device at a position corresponding to the second jet impact zone 6;

[0032] It should be noted that the transition connector 7 is a cylinder with an open end. The open end of the transition connector 7 is connected to the water inlet hole 406, and the other end of the transition connector 7 is a closed end. The jet enters the transition connector 7 along the water inlet hole 406, hits the closed end of the transition connector 7 to change direction, and then changes direction to be ejected from the water outlet hole 701 on the outer surface of the transition connector 7, and impacts the inner wall of the jet impact area 5. The jet after collision carries relatively rich bubbles and is milky white. It is sprayed out through the water outlet, which can more efficiently clean the grease on the head.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
