[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] In order to solve the technical problems in the prior art, the present invention will be further described in conjunction with the accompanying drawings and embodiments:

[0024] like Figures 1 to 3 As shown in the figure, this utility model embodiment discloses a pipe cleaning device, including a cleaning nozzle 1, a fixed base 2, and a high-pressure water pipe 3. One end of the high-pressure water pipe 3 is provided with a locking seat 31 and a jet pipe 32. The high-pressure water pipe 3 is detachably connected to the fixed base 2 through the locking seat 31. The lower end of the locking seat 31 and the fixed base 2 forms a bearing cavity 4. A bearing 5 is installed in the bearing cavity 4. The upper and lower ends of the fixed base 2 are connected to form a rotating cavity 21. The lower end of the cleaning nozzle 1 is connected to a first rotating body 11. The first rotating body 11 extends into the rotating cavity 21 and is rotatably connected to the bearing 5. The first rotating body 11 is provided with a first water inlet channel. The jet pipe 32 extends into the first water inlet channel and extends into the inner cavity of the cleaning nozzle 1.

[0025] The cleaning nozzle 1, the mounting base 2, and the high-pressure water pipe 3 are connected in sequence, adopting a split structure. The first rotating body 11 at the lower end of the cleaning nozzle 1 extends into the mounting base 2 and is rotatably connected to the bearing 5, ensuring stable rotation of the nozzle. The jet pipe 32 is designed to ensure the impact force of the water flow. During use, the cleaning nozzle 1 is inserted into the pipe to be cleaned, and the high-pressure water pipe 3 is connected to the high-pressure water flow. Driven by the high-pressure water flow, it rotates freely, achieving 360-degree all-round cleaning of the inner wall of the pipe. No manual angle adjustment is required, resulting in high cleaning efficiency.

[0026] The locking seat 31 and the fixed seat 2 are detachable, making it convenient to disassemble, install, and replace parts. During assembly, a suitable cleaning nozzle 1 is inserted into the fixed seat 2. After assembling the first rotating body 11 and the bearing 5, the high-pressure water pipe 3 is fixedly connected to the fixed seat 2. The bearing 5 is confined within the bearing cavity 4. The high-pressure water pipe 3, the jet pipe 32, and the cleaning nozzle 1 are interconnected.

[0027] The cleaning nozzle 1 and the first rotating body 11 can be fixedly connected. The length of the first rotating body 11 is greater than the length of the fixed base 2. When the cleaning nozzle 1 needs to be replaced, one end of the first rotating body 11 connected to the bearing 5 moves downward, and the bearing 5 can extend out of the fixed base 2. The connection between the bearing 5 and the first rotating body 11 can be removed for replacement.

[0028] In some embodiments, a second rotating body 6 is fixedly installed in the middle of the bearing 5. The second rotating body 6 is detachably installed from the first rotating body 11. The second rotating body 6 is vertically connected to form a second water inlet channel, and the second water inlet channel is interconnected with the first water inlet channel.

[0029] The second rotating body 6 and the first rotating body 11 are detachably installed, which facilitates the replacement of different cleaning nozzles 1 to meet the needs of different pipeline cleaning. The second rotating body 6 and the bearing 5 can be pre-fixed and installed. After selecting a suitable cleaning nozzle 1, it is inserted into the fixing seat 2 to connect with the second rotating body 6.

[0030] Furthermore, the second rotating body 6 is threadedly connected to the first rotating body 11, and the rotation direction of the cleaning nozzle 1 is opposite to the direction of the thread. A second rotating body 6 is added inside the bearing 5, which is threadedly connected to the first rotating body 11, and the direction of the thread is opposite to the rotation direction of the nozzle to prevent loosening.

[0031] In some implementations, such as Figure 4 As shown, one end of the jet pipe 32 that extends into the inner cavity of the cleaning nozzle 1 is bent to form a guide head 8. The guide head 8 is formed by bending the end of the jet pipe 32 to optimize the direction of water flow impact.

[0032] When the first rotating body 11 and the second rotating body 6 are threaded together, during the rotational installation process, the water outlet direction of the guide head 8 can be observed through the first water outlet 101 and the second water outlet 102 on the cleaning nozzle 1 to ensure that the thread rotation direction is opposite to the rotation direction of the cleaning nozzle 1, thus ensuring that the cleaning process proceeds smoothly.

[0033] In some embodiments, the upper part of the cleaning nozzle 1 is provided with a plurality of first water outlets 101, and the lower part of the cleaning nozzle 1 is provided with a plurality of second water outlets 102. A second water outlet 102 is provided between adjacent first water outlets 101. The first water outlets 101 and the second water outlets 102 are inclined relative to each other or are arranged in an arc shape.

[0034] The cleaning nozzle 1 has an inclined or arc-shaped first water outlet 101 and a second water outlet 102 at its upper and lower parts, respectively. Their staggered distribution forms a multi-directional jet, enhancing the turbulence effect and improving cleaning efficiency. A high-pressure water pipe 3 is connected to an external water pump. High-pressure water flows through the jet pipe 32, impacting the inner cavity of the cleaning nozzle 1 and driving the cleaning nozzle 1 and the first rotating body 11 to rotate. The water flow from the first water outlet 101 and the second water outlet 102 creates a reaction force, maintaining the continuous rotation of the nozzle.

[0035] In some implementations, such as Figure 3As shown, a cleaning blade sleeve 7 is also provided. The cleaning blade sleeve 7 is fixedly fitted onto the outside of the cleaning nozzle 1. The cleaning blade sleeve 7 has through holes (not shown in the figure) adapted to the first water outlet 101 and the second water outlet 102. Multiple blades 71 are arranged circumferentially on the outer periphery of the cleaning blade sleeve 7.

[0036] Furthermore, the cleaning sheath 7 and the blade 71 are made of elastic materials. These elastic materials may include TPU, TPE, etc.

[0037] The blade 71 of the cleaning blade sleeve 7 scrapes dirt close to the inner wall of the pipe, and its elastic material adapts to changes in pipe diameter. When the blade sleeve needs to be replaced, the entire cleaning blade sleeve 7 is removed to complete the replacement.

[0038] In some embodiments, multiple fixed protrusions (not shown in the figure) are distributed on the outer periphery of the cleaning nozzle 1.

[0039] In some embodiments, the lower end of the fixing seat 2 is provided with a base 22, which is threaded, snap-fitted or bolted to the locking seat 31.

[0040] Furthermore, the cleaning nozzle 1, the mounting base 2, and the high-pressure water pipe 3 are made of stainless steel.

[0041] Made of stainless steel for corrosion protection; the fixing seat 2 and the locking seat 31 are flexibly connected by threads, snaps or bolts.

[0042] The main functions of this utility model are:

[0043] 1. The high-pressure water pipe and the fixed base can be quickly disassembled and installed for easy maintenance. The bearing and jet pipe design ensures stable rotation of the cleaning nozzle. The water outlets of the cleaning nozzle are distributed vertically to form a three-dimensional cleaning network. The multi-angle jet covers the inner wall of the pipe without dead corners, enhances the water flow turbulence effect, and improves cleaning efficiency.

[0044] 2. The cleaning nozzle is detachable and installable through the first and second rotating bodies, which facilitates component replacement and maintenance, and the modular structure reduces maintenance costs.

[0045] 3. Add a cleaning blade sleeve. The cleaning nozzle is designed with a fixing protrusion to improve the fixing reliability of the cleaning blade sleeve and prevent the blade sleeve from slipping and shifting. The blade scrapes the inner wall of the pipe. The blade sleeve body and blade are made of elastic material, which is not easy to damage the pipe wall.

[0046] In summary, any other corresponding modifications made by those skilled in the art after reading this utility model document, based on the technical solution and concept of this utility model without creative mental effort, shall all fall within the scope of protection of this utility model.
