[0003] In view of the defects in the prior art, the main purpose of the utility model is to overcome the shortcomings of the prior art, and a pipe outer cleaning assembly for pipe is disclosed, which comprises a body and a cover plate, a through hole allowing the pipe to pass through is arranged between the body and the cover plate, an outer wall and an inner wall are axially arranged on the outer periphery and the inner periphery of the body, the cover plate is installed on the body, a liquid guide cavity is formed between the cover plate and the body, and the water outlet is formed between the cover plate and the inner wall.

[0004] Further, a liquid passage hole is arranged on the outer wall of the body.

[0005] Further, the liquid passage hole is provided with one or two.

[0006] Further, when the liquid passage hole is provided with two, the liquid passage holes are symmetrically arranged on both sides of the body.

[0007] Further, an annular groove is arranged on the abutting surface of the body and the cover plate, and a sealing ring is arranged in the annular groove.

[0008] Further, the sealing ring protrudes from the surface of the body.

[0009] Further, the cover plate and the body are fastened by screws.

[0010] Further, first chamfers are arranged at both ends of the through hole on the body.

[0011] The utility model has the following beneficial effects:

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] An external cleaning assembly for pipes, such as Figures 1-3 As shown, it includes a body 1 and a cover plate 2. A through hole 3 is provided between the body 1 and the cover plate 2 to allow the pipe to pass through. An outer wall 11 and an inner wall 12 are axially protruding from the outer and inner circumferences of the body 1. The cover plate 2 is installed on the body 1. A liquid guiding cavity 4 is formed between the cover plate 2 and the body 1. An outlet 14 is formed between the cover plate 2 and the inner wall 12.

[0020] In one embodiment, such as Figures 1-3 As shown, a liquid passage hole 13 is provided on the outer wall 11 of the main body 1; it is used to connect a water source so that the cleaning liquid is sent into the liquid guiding cavity and then sprayed out from the water outlet.

[0021] In one embodiment, such as Figures 1-3 As shown, one liquid passage hole 13 is provided, and multiple cleaning components are connected in parallel through water pipes.

[0022] In another embodiment, such as Figures 1-3 As shown, two fluid passage holes 13 are provided, located on opposite sides of the outer wall 11. During installation, the fluid passage holes 13 are distributed left and right, and adjacent fluid passage holes are connected by pipes to connect the cleaning components in series, reducing the use of pipes. Of course, two fluid passage holes 13 can also be provided in parallel, that is, one of the fluid passage holes 13 can be blocked with a plug.

[0023] In one embodiment, such as Figures 1-3As shown, an annular groove 15 is provided on the mating surface of the body 1 and the cover plate 2, and a sealing ring is provided in the annular groove 15.

[0024] In the above embodiments, such as Figures 1-3 As shown, the sealing ring protrudes from the surface of the body 1. After the cover plate 2 is placed on the body 1, the sealing ring fits tightly against the cover plate 2, achieving a seal between the body 1 and the cover plate 2. This ensures that liquid can only be sprayed out from the outlet, preventing leakage from affecting the pressure of the water sprayed from the outlet and thus affecting the cleaning effect.

[0025] In one embodiment, such as Figures 1-3 As shown, the cover plate 2 and the body 1 are fastened together by screws. Specifically, the body 1 and the cover plate 2 are respectively provided with screw holes 16 and connecting holes 21. The screws pass through the connecting holes 21 and connect to the screw holes 16. By rotating the screws, the cover plate 2 can be tightly pressed onto the body 1. Preferably, at least three sets of connecting holes 21 and screw holes 16 are provided, and they are equally spaced on the same circumference.

[0026] In one embodiment, such as Figures 1-3 As shown, both ends of the through hole on the body 1 are provided with a first chamfer 17, which facilitates the pipe to enter the through hole.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Any modifications or equivalent substitutions to the present utility model without departing from the spirit and scope thereof should be covered within the protection scope of the claims of the present utility model.
