[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0030] Components not described in detail in the following embodiments are all prior art, and those skilled in the art can use conventional technical means in this field. The positional descriptions such as "upper part," "lower part," "bottom surface," "side surface," "top," and "bottom end" used in the following embodiments are only for clearly describing the relative positional relationship between components and are not intended to limit the protection scope of this utility model.

[0031] like Figures 1-7 As shown in the figure: This utility model proposes a cleaning structure, including: stator 11, rotor 13, clamping ring 15, diversion tower 16 and cleaning brush 21;

[0032] The stator 11 is provided with a liquid inlet channel, and the rotor 13 is fixedly provided with a cleaning liquid pipe 19 through it along its axial direction. One end of the cleaning liquid pipe 19 is a liquid inlet for external cleaning liquid input, and the other end is a liquid outlet. The rotor 13 is rotatably connected to the stator 11 and is limited by the clamping ring 15.

[0033] The top outer circumference of the rotor 13 is provided with a groove 132 to form a compressed air duct 17. The wall of the cleaning fluid pipe 19 is provided with a diversion duct 18 that communicates with the compressed air duct 17. The diversion duct 18 is a spiral duct that extends spirally along the axial direction of the rotor 13. The bottom of the rotor 13 is connected to a diversion tower 16 that communicates with the outlet of the cleaning fluid pipe 19. A cleaning brush 21 is connected to the diversion tower 16.

[0034] External cleaning fluid enters the cleaning fluid pipe 19 through the inlet and is then diverted by the diversion tower 16 and delivered to the cleaning brush 21 before flowing out from the cleaning brush 21. Compressed air enters the duct 18 through the compressed air duct 17 and then acts as a backflow force on the cleaning fluid pipe 19. Since the cleaning fluid pipe 19 is fixedly connected to the rotor 13, the rotor 13 rotates relative to the stator 11 and drives the cleaning brush 21 to rotate, thereby achieving a cleaning function that combines scrubbing and washing.

[0035] It should be noted that the air duct 18 can also adopt other existing technologies, such as a tangential jet air duct, in which multiple tangential air ducts are evenly distributed around the rotor, and the outlet direction of the air duct is consistent with the rotor tangent. Compressed air is ejected from the tangential air duct, generating a reaction force to drive the rotor to rotate; another example is to use a combination of axial and tangential air ducts, in which compressed air first enters along the axial direction and then is ejected through the tangential air duct. The axial airflow provides thrust, and the tangential airflow generates rotational torque, which together drive the rotor to rotate; an annular air duct can also be used, in which an annular air duct is opened inside or on the surface of the rotor. The air duct is distributed along the circumference. When the compressed air passes through the annular air duct, it generates a uniform tangential force to drive the rotor to rotate.

[0036] In practical use, multiple cleaning structures are fixedly installed onto the inner wall of a frame via stators 11 (solid fixing methods are existing technologies, such as screwing, snap-fitting, and welding). The frame is equipped with cleaning fluid channels connected to cleaning fluid pipes 19 of each cleaning structure and compressed air channels connected to compressed air ducts 17 of each cleaning structure. Cleaning fluid and compressed air are respectively delivered to each cleaning structure through the cleaning fluid channels and compressed air channels. The frame can be adaptively designed according to the appearance of the object to be cleaned. For example, if the object is rectangular, the frame is designed as an inverted U-shape. The object moves slowly through the inverted U-shape, and the cleaning structures installed on the inner wall of the inverted U-shape clean the surface of the object.

[0037] Compared with the prior art, this utility model combines scrubbing and washing with water, and does not require mechanical power drive. The speed of the cleaning brush 21 can be flexibly adjusted. In actual use, the user can adjust the speed of the rotor 13 by controlling the air pressure of compressed air according to actual needs, thereby achieving controllable speed of the cleaning brush 21. This can effectively improve the cleaning effect without causing irreversible damage to the surface of the object to be cleaned. Moreover, the overall structure is simple and compact, easy to maintain, low in operating cost, low in energy consumption and low in noise.

[0038] As a preferred technical solution, in another embodiment of the present invention, a cavity is formed in the stator 11, and a coil 22 and a power supply component 23 are arranged in the cavity. The coil 22 is arranged around the outer periphery of the cleaning fluid pipe 19, and the power supply component 23 is electrically connected to the coil 22.

[0039] In specific configurations, coil 22 and power supply assembly 23 can be fixedly connected to stator 11 or rotor 13, generating a magnetic field around energized coil 22. Although magnetic field treatment does not change the concentration of calcium and magnesium ions in the water (i.e., it does not change the water hardness), it can change the crystal morphology of calcium and magnesium ions in the water, transforming the formed calcium carbonate and other scale crystals from a dense calcite type to a loose aragonite type. This inhibits the deposition of scale on the inner wall of the cleaning fluid pipe and the surface of the cleaning components, maintaining the cleanliness of the driving structure of the cleaning components. At the same time, magnetization treatment can improve the permeability, lubricity, and adsorption of water, which helps to improve the cleaning effect. Moreover, if the outer shell of the object to be cleaned is made of certain specific steel materials, such as 20G steel or 304 stainless steel, magnetized water can also affect the passivation film on its surface, exhibiting a significant corrosion inhibition effect.

[0040] It should be noted that both coil 22 and power supply component 23 are existing technologies. Any existing technology that can provide power to coil 22 can be used as the power supply component 23 of this utility model, and any existing technology that can generate a magnetic field when energized can be used as coil 22 of this utility model.

[0041] As a preferred technical solution, in another embodiment of this utility model, the coil 22 is arranged in a serpentine twist around the outer periphery of the cleaning fluid pipe 19.

[0042] As a preferred technical solution, in another embodiment of this utility model, one end of the rotor 13 is provided with a first sealing groove 131 and a second sealing groove 133, and a first sealing ring 12 and a second sealing ring 14 are respectively provided in the first sealing groove 131 and the second sealing groove 133 to block pollutants, reduce friction, and adapt to displacement, etc.; both ends of the rotor 13 are rotatably connected to the stator 11 through a bearing 26.

[0043] As a preferred technical solution, in another embodiment of this utility model, bearing 26 is a ceramic bearing. Ceramic bearings have advantages such as high hardness, high wear resistance, low coefficient of friction, corrosion resistance, high temperature resistance, cold resistance and low noise. Using them in this utility model will help to further optimize the performance of the cleaning structure.

[0044] As a preferred technical solution, another embodiment of this utility model further includes a first retaining ring 24 and a second retaining ring 25. The upper and lower parts of the rotor 13 are respectively provided with engaging steps 134 for mounting the first retaining ring 24 and the second retaining ring 25. The first retaining ring 24 and the second retaining ring 25 are used to axially fix the two bearings 26, ensuring the normal operation of the bearings 26 and extending their service life.

[0045] As a preferred technical solution, in another embodiment of this utility model, the diversion tower 16 is connected to one or more cleaning brushes 21 through the docking mechanism 20, and the interior of the cleaning brushes 21 is connected to the diversion tower 16 through the docking mechanism 20.

[0046] It should be noted that:

[0047] (1) The diversion tower 16 mainly serves to divert the cleaning fluid in the cleaning fluid pipeline 19 to form a cleaning flow that matches the number of cleaning brushes 21, and delivers it to each cleaning brush. Its specific structure is existing technology, and those skilled in the art can flexibly select and use it according to actual needs.

[0048] (2) The docking structure 20 mainly serves as a connection, that is, to connect the cleaning brush 21 with the diversion tower 16. Its specific structure is existing technology, and those skilled in the art can flexibly select and use it according to actual needs.

[0049] As a preferred technical solution, in another embodiment of this utility model, the cleaning brush 21 is specifically a hair follicle brush. The hair follicle brush is made of a flexible material and specifically includes a hair follicle brush body 211. Hair follicles 212 are distributed on the outer peripheral surface and the end face of the free end of the hair follicle brush body 211. The top of the hair follicle 212 is provided with a hair follicle hole 213.

[0050] The cleaning fluid, such as water, enters the cleaning fluid pipe 19 from the outside through the inlet. After being diverted by the distribution tower 16 at the outlet, it reaches the cleaning brush 21. When the water in the cleaning brush 21 reaches a certain pressure, the pores 213 of the brush open, and the water begins to atomize and be sprayed evenly from the pores 213. The water is sprayed out in the form of a mist, which performs both blowing and scrubbing functions, better dissolving the dirt adhering to the surface of the equipment to be cleaned and protecting its material from damage.

[0051] As a preferred technical solution, in another embodiment of this utility model, the number of hair follicle brushes is two, and the two hair follicle brushes have different shapes. For example, one hair follicle brush is curved and the other is arc-shaped. The two hair follicle brushes rotate under the drive of rotor 13, and can swing freely according to different resistance and power, thereby forming a mesh structure that can tightly adhere to the surface of the object to be cleaned, achieving a thorough cleaning effect without dead angles and eliminating cleaning blind spots.

[0052] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make modifications, alterations, substitutions, and variations to the above embodiments within the scope of the present invention. Furthermore, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of the different embodiments or examples.
