[0049] In the following, the term "comprising" or "may comprise" that can be used in various embodiments of the present application indicates the presence of the disclosed functions, operations, or elements, and does not limit the addition of one or more functions, operations, or elements. In addition, as used in various embodiments of the present application, the terms "comprising", "having" and their cognates are only intended to represent specific features, numbers, steps, operations, elements, components, or combinations of the foregoing items, and should not be construed as precluding the existence or addition of the possibility of one or more other features, numbers, steps, operations, elements, components, or combinations of the foregoing items.

[0050] As Figures 1-5 shown, the present application provides a high - pressure cleaning gun, comprising:

[0051] A main body 1, including a housing 11, a fluid pipeline 12, and a driving device 13. The fluid pipeline 12 is arranged inside the housing 11. One end of the fluid pipeline 12 penetrates to the outside of the housing 11 to form a water inlet end 121 for connecting with external fluid, and the other end of the fluid pipeline 12 also penetrates to the outside of the housing 11 to form a water outlet end 122; The driving device 13 is arranged inside the housing 11 and is used to drive external fluid to flow in from the water inlet end 121 and flow out from the water outlet end 122;

[0052] A spraying body 2. There is a rotary clamping structure 4 between the spraying body 2 and the water outlet end 122. The spraying body 2 is connected to the water outlet end 122 through the rotary clamping structure 4. The inner cavity 21 of the spraying body communicates with the inner cavity 123 of the fluid pipeline. The spraying body 2 is used to dock the external fluid flowing out from the water outlet end 122 and spray.

[0053] In this application, a detachable connection between the ejector body 2 and the water outlet end 122 of the main body 1 is achieved through a rotary clamping structure 4, making it convenient to disassemble and assemble the ejector body 2 and the main body 1, so as to facilitate maintenance and replacement.

[0054] As Figures 1-5 shown, the rotary clamping structure 4 includes at least one clamping block 41 and at least one clamping groove 42. At least one clamping block 41 is arranged at the end of the ejector body 2, and at least one clamping groove 42 is arranged on the inner wall of the water outlet end 122. The clamping block 41 moves and rotates along the clamping groove 42 for clamping the ejector body 2 to the water outlet end 122. In this application, through the cooperation of the clamping block 41 and the clamping groove 42, a detachable connection between the ejector body 2 and the water outlet end 122 of the main body 1 is achieved, making it convenient to disassemble and assemble the ejector body 2 and the main body 1, so as to facilitate maintenance and replacement.

[0055] Specifically, as Figures 6-11 shown, the clamping groove 42 has a first part 421 and a second part 422. The first part 421 extends along the extending direction of the water outlet end 122 for guiding the ejector body 2 to move along the first part 421; the second part 422 is connected to the first part 421 and extends along the circumferential direction of the water outlet end 122 for restricting the movement of the clamping block 41 when the clamping block 41 rotates to the second part 422, so that the clamping block 41 is clamped to the water outlet end 122. In this application, the first part 421 guides the movement of the clamping block 41, and the second part 422 restricts the movement of the clamping block 41 to achieve the clamping of the clamping block 41 to the water outlet end 122, making the connection between the ejector body 2 and the main body 1 stable; when disassembling the ejector body 2, the clamping block 41 is rotated away from the second part 422 and moved along the first part 421 to move out of the water outlet end 122, thereby realizing the disassembly between the ejector body 2 and the main body 1, which is convenient for disassembly and assembly and has a stable structure.

[0056] Among them, the first part 421 includes a groove, and the depth of the groove is not less than the thickness of the clamping block 41; the second part 422 includes a clamping hole, and the depth of the clamping hole is also not less than the thickness of the clamping block 41, and the depth of the clamping hole is greater than the depth of the groove.

[0057] In this embodiment, the depth of the groove is equal to the thickness of the clamping block 41, and the clamping block 41 moves along the groove, making the structure between the ejector body 2 and the water outlet end 122 more stable and reliable, and the movement of the ejector body 2 in the water outlet end 122 more stable.

[0058] The locking process of the ejector body 2 and the water outlet end 122 in this application is as follows:

[0059] As Figure 6 、 7 shown, the ejector body 2 enters the water outlet end 122, and the clamping block 41 moves along the first part 421, and then as Figure 8 、 9As shown, the ejector 2 rotates, and the clamping block 41 rotates until the second part 422 abuts against the inner wall of the second part 422. At this time, the ejector 2 continues to penetrate into the water outlet end 122 until Figure 10 , 11 as shown, the clamping block 41 is completely located in the second part 422 to achieve locking.

[0060] As Figures 1-11 shown, at least one clamping block 41 includes two clamping blocks 41, and the two clamping blocks 41 are circumferentially spaced along the end of the ejector 2; at least one clamping groove 42 includes two clamping grooves 42, and the two clamping grooves 42 are circumferentially spaced along the water outlet end 122. The two clamping blocks 41 and the two clamping grooves 42 correspond to each other and are used to rotate and clamp the ejector 2 to the water outlet end 122. Through the design of the two clamping blocks 41 and the two clamping grooves 42 in this application, the stability and reliability of the connection between the ejector 2 and the water outlet end 122 are further enhanced.

[0061] As Figures 1-5 shown, the driving device 13 includes a booster pump 131 and a motor 132. The motor 132 is drivingly connected to the booster pump 131, and the booster pump 131 is connected to the fluid pipeline 12. Among them, the booster pump 131 is used to increase the pressure of the fluid in the fluid pipeline 12, and the motor 132 is used to drive the booster pump.

[0062] As Figures 1-5 shown, the water outlet end 122 includes a first connecting portion 1221 and a second connecting portion 1222 connected to each other. The inner cavity of the first connecting portion 1221 is larger than the inner cavity of the second connecting portion 1222, and the clamping groove 42 is located on the inner wall of the first connecting portion 1221; the ejector 2 includes a first acting portion 22 and a second acting portion 23 connected to each other, and the clamping block 41 is located on the first acting portion 22. When the first acting portion 22 is located in the first connecting portion 1221 and the clamping block 41 is placed in the clamping groove 42, the outer wall of the second acting portion 23 contacts the inner wall of the second connecting portion 1222. In this application, through the cooperation of the first acting portion 22 and the first connecting portion 1221, the ejector 2 and the water outlet end 122 are clamped, and through the cooperation of the second acting portion 23 and the second connecting portion 1222, the outer wall of the ejector 2 and the inner wall of the water outlet end 122 are tightly connected, so that the ejector 2 and the water outlet end 122 are tightly connected, and the fluid of the water outlet end 122 can better enter the water outlet end 122.

[0063] Among them, a sealing ring is provided between the second acting portion 23 and the second connecting portion 1222, and the tightness of the connection between the second acting portion 23 and the second connecting portion 1222 is further improved through the sealing ring.

[0064] As Figures 1-6As shown, the outer diameter of at least one section of the second connecting portion 1222 decreases from one end close to the first connecting portion 1221 to the other end, and the inner diameter of the second connecting portion 1222 is the same. By designing different outer diameters, the connection between the second connecting portion 1222 and the second acting portion 23 is made more stable.

[0065] In this embodiment, the outer diameter of one end of the second connecting portion 1222 close to the first connecting portion 1221 is greater than the outer diameter of one end of the second connecting portion 1222 close to the driving device 13, and the outer diameter of the middle portion of the second connecting portion 1222 decreases from one end close to the first connecting portion 1221 to the other end.

[0066] As Figure 4 shown, a nozzle 24 is provided on the side of the ejector 2 away from the main body 1. The nozzle 24 includes a conical nozzle 24 or a flat nozzle 24. By designing different nozzles 24, they can be replaced according to different cleaning requirements, with higher flexibility.

[0067] As Figures 12-14 shown, the high-pressure cleaning gun further includes a power supply body 3. There are a first connecting component 5 and a second connecting component 6 between the power supply body 3 and the main body 1. The power supply body 3 is detachably connected to the main body 1 through the first connecting component 5 and is electrically connected to the main body 1 through the second connecting component 6. In this application, the detachable connection and electrical connection between the power supply body 3 and the main body 1 are realized through the first connecting component 5 and the second connecting component 6, so that the main body 1 and the power supply body 3 are independent of each other, improving the safety and reliability of the product, and at the same time being convenient for disassembly and replacement for maintenance.

[0068] In this embodiment, the first connecting component 5 includes a socket 51 and a plug 52. The socket 51 is provided on the main body 1, and the plug 52 is provided on the power supply body 3.
