Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a cleaning component drive structure with water softening function. Background Technology

[0002] As is well known, mechanical cleaning replaces manual cleaning, which has the advantages of saving manpower, high cleaning intensity, and high cleaning efficiency. However, existing mechanical cleaning still has the following drawbacks: (1) Mechanical power drive requires more electrical energy to drive the movement of the cleaning parts to wipe the objects to be cleaned, resulting in high energy consumption and high operating costs; (2) Most use tap water as the cleaning fluid, which is hard water and easily forms scale during the cleaning process. This scale can clog pipes, nozzles and other parts, leading to a decrease in cleaning efficiency or even damage. It can also easily adhere to the surface of the equipment to be cleaned, affecting the cleaning effect. Therefore, more frequent maintenance and upkeep may be required afterward, such as replacing brush heads, cleaning pipes and nozzles, which further increases the operating cost. How to improve the driving structure of the cleaning parts to reduce energy consumption, save cleaning fluid, and improve the surface quality of the cleaned parts is a technical problem that needs to be solved. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the present invention provides a cleaning component drive structure with water softening function.

[0004] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0006] The rotor is located inside the stator and is rotatably connected to the stator and limited by a clamping ring; a liquid inlet channel is provided inside the stator, and a cleaning liquid pipe is fixedly inserted through the rotor along its axial direction. One end of the cleaning liquid pipe is the liquid inlet, and the other end is the liquid outlet and is used to connect the cleaning components; a cavity is opened inside the stator, and a coil and a power supply component are provided in the cavity. The coil is arranged around the outer periphery of the cleaning liquid pipe, and the power supply component is electrically connected to the coil.

[0007] The top outer circumference of the rotor is provided with a groove to form a compressed air duct. The cleaning fluid pipe is provided with a guide duct that is connected to the compressed air duct. The guide duct is a spiral duct that extends spirally along the rotor axis.

[0008] Compressed air enters the duct through the compressed air duct, and then the backflow acts on the rotor, causing the rotor to rotate relative to the stator and drive the cleaning component to rotate.

[0009] Preferably, a diversion component is also provided at the liquid outlet, and a cleaning component connection structure is provided on the diversion component.

[0010] Preferably, the coil is twisted in a serpentine shape and then arranged around the outer periphery of the cleaning fluid pipe.

[0025] 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.

[0026] 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.

[0027] like Figures 1-6 As shown in the figure: This utility model proposes a cleaning component drive structure with water softening function, including: stator 11, rotor 13 and clamping ring 15;

[0028] The rotor 13 is located inside the stator 11 and is rotatably connected to the stator 11 and limited by the clamping ring 15; the stator 11 is provided with a liquid inlet channel, and a cleaning liquid pipe 19 is fixedly inserted through the rotor 13 along its axial direction. One end of the cleaning liquid pipe 19 is a liquid inlet, and the other end is a liquid outlet and is used to connect to the cleaning component; a cavity is opened inside the stator 11, and a coil 22 and a power supply component 23 are provided in the cavity. The coil 22 is arranged around the outer periphery of the cleaning liquid pipe 19, and the power supply component 23 is electrically connected to the coil 22. The coil 22 and the power supply component 23 can be fixedly connected to the stator 11 or to the rotor 13.

[0029] The top outer circumference of the rotor 13 is provided with a groove 132 to form a compressed air duct 17. The cleaning fluid pipe 19 is provided with a guide air duct 18 that communicates with the compressed air duct 17. The guide air duct 18 is a spiral duct that extends spirally along the axial direction of the rotor 13.

[0030] Compressed air enters the duct 18 through the compressed air duct 17. The backflow of compressed air acts 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 component to rotate.

[0031] In use, tap water is introduced into the inlet of the self-cleaning liquid pipe 19, and existing cleaning components such as cleaning brushes are installed at the outlet of the cleaning liquid pipe 19. Compressed air enters the duct 18 through the compressed air duct 17. Users can adjust the speed of the rotor 13 by controlling the air pressure of the compressed air according to actual needs, thereby achieving controllable speed of the cleaning components. 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.

[0032] It should be noted that:

[0033] (1) 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. Any existing technology that can generate a magnetic field when energized can be used as coil 22 of this utility model.

[0034] (2) Other existing technologies can also be used for the air duct 18, such as tangential jet air duct, that is, multiple tangential air ducts are evenly distributed around the rotor, and the outlet direction of the air duct is consistent with the tangent of the rotor. Compressed air is ejected from the tangential air duct, generating a reaction force to drive the rotor to rotate; another example is the use of a combination of axial and tangential air ducts, where 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; annular air ducts can also be used, that is, annular air ducts are opened inside or on the surface of the rotor. The air ducts are distributed along the circumference. When the compressed air passes through the annular air duct, a uniform tangential force is generated to drive the rotor to rotate.

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] (1) Reduce scale formation

[0037] A magnetic field is generated around the energized coil 22. This magnetic field acts on the cleaning fluid flowing through the cleaning fluid pipe 19. Although the 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, causing the formed calcium carbonate and other scale crystals to change 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, the magnetization treatment can improve the permeability, lubricity, and adsorption of water, which helps to improve the cleaning effect.

[0038] (2) Extend equipment life

[0039] Scale can clog important components in the drive structure of cleaning devices, leading to reduced drive efficiency or even damage. Magnetizing hard water reduces scale formation, thus reducing equipment maintenance needs and extending equipment lifespan.

[0040] (3) Saves on detergent usage and improves cleaning efficiency

[0041] When water is used as a solvent and other cleaning agents are added, the magnetized water is less likely to react with the cleaning agents, so it will not reduce its cleaning ability and will help the cleaning agents to perform better cleaning and improve cleaning efficiency.

[0042] (4) Improve the quality of the cleaned surface

[0043] Hard water can leave water stains or spots on cleaned surfaces, while magnetized water effectively avoids these problems, leaving surfaces cleaner and shinier. Furthermore, if the object being cleaned has a casing made of certain types of steel, such as 20G steel or 304 stainless steel, magnetized water can also affect the passivation film on its surface, exhibiting a significant corrosion-inhibiting effect.

[0044] (5) Environmental protection

[0045] Reducing the amount of cleaning agents used and the formation of limescale helps to make wastewater treatment easier and reduce environmental pollution.

[0046] As a preferred technical solution, in another embodiment of this utility model, a diversion component is further provided at the liquid outlet, and a cleaning component connection structure is provided on the diversion component. For example, a diversion tower 16 (prior art) with two outlets is provided at the liquid outlet, and each outlet is connected to a cleaning brush 21 (prior art) through a docking mechanism 20 (prior art). The cleaning brush 21 is preferably a soft cleaning brush. The diversion tower 16 diverts the cleaning liquid in the cleaning liquid pipeline 19 to form a cleaning flow matching the number of cleaning brushes 21 and delivers it to each cleaning brush 21 respectively.

[0047] To achieve a strong magnetic field with a limited current, the coil in this invention preferably adopts one of two arrangements: One arrangement is that the coil 22 is twisted in a serpentine shape and wrapped around the outer periphery of the cleaning fluid pipe 19. The other arrangement is that the coil 22 is spirally wound around the outer periphery of the cleaning fluid pipe 19 and extends along the axial direction of the pipe. These two arrangements result in a more concentrated magnetic field and a stronger magnetic field.

[0048] Furthermore, based on the above coil arrangement, in order to further enhance the magnetic field strength, it is possible to use a high permeability material as the magnetic core inside the coil, that is, to set an iron core or soft magnetic material inside the cleaning fluid pipe 19, and to significantly enhance the magnetic field strength through magnetic separation winding.

[0049] As a preferred technical solution, in another embodiment of this utility model, another coil is provided inside the cleaning fluid pipe 19. The internal coil and the coil arranged around the outer periphery of the cleaning fluid pipe 19 are coaxially arranged, which can superimpose the magnetic fields and enhance the overall magnetic field strength.

[0050] 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 contaminants, reduce friction, and adapt to displacement, etc.; both ends of the rotor 13 are rotatably connected to the stator 11 through a bearing 26; the bearing 26 is preferably a ceramic bearing with advantages such as high hardness, high wear resistance, low coefficient of friction, corrosion resistance, high temperature resistance, cold resistance and low noise.

[0051] As a preferred technical solution, another embodiment of the present invention further includes a first retaining ring 24 and a second retaining ring 25 for axially fixing the two bearings 26, so as to ensure the normal operation of the bearings 26 and extend their service life; the upper and lower parts of the rotor 13 are respectively provided with engagement steps 134 for installing the first retaining ring 24 and the second retaining ring 25.

[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.
