Description

Technical Field

[0001] The invention relates to the technical field of cleaning tools, and in particular to a handheld electric descaling brush which is convenient for self-cleaning. Background Art

[0002] As an outstanding representative of modern cleaning technology, the electric cleaning brush is rapidly changing the way we clean with its unique structure and significant advantages. It has a compact structure and is usually composed of core components such as a motor, a brush head, a battery pack and a control panel. The motor, as a power source, drives the brush head to rotate at high speed to generate a strong cleaning force; the brush head is made of highly wear-resistant and highly elastic materials, which can fit tightly to the surface to be cleaned and effectively remove stains and impurities; the battery pack ensures the portability and durability of the electric cleaning brush in an environment without an external power supply; and the control panel provides a simple and clear operating interface, allowing users to easily control the cleaning process.

[0003] There are two types of electric cleaning brushes, one is a flat rotating brush head and the other is a roller rotating brush head.

[0004] For example, patent CN222264683U discloses an electric cleaning brush of a flat rotating brush head type, which includes a lower shell cover, an upper shell cover is fixedly connected to the top of the lower shell cover, a fixed ring plate is fixedly connected to the head inside the upper shell cover, a mounting hole is provided inside the fixed ring plate, a driving motor is provided inside the mounting hole, the output end of the driving motor passes through the lower shell cover and is fixedly connected to the rotating head, a brush head is sleeved and installed on the surface of the rotating head, and a fixing piece is fixedly installed inside the lower shell cover and the upper shell cover and located at the handle. In the present invention, the cleaning brush can start the driving motor by pressing the control button, the driving motor starts to drive the rotating head to rotate, and the rotating head rotates to drive the brush head to rotate, which can automatically clean the object, thereby reducing the labor of the user, and at the same time, the rotating head is embedded in the brush head, which can be easily disassembled and replaced.

[0005] For example, patent CN221511249U discloses an electric cleaning brush of roller rotation type, which includes a handle and a brush handle assembly, the brush handle assembly includes a frame, a motor and a roller brush, the roller brush includes a roller, the handle is connected to the frame, the motor is mounted on the frame, a fixed shaft is also provided on the frame, the motor has an output shaft, and the output shaft and the fixed shaft are arranged on the same central axis; the two ends of the roller are respectively provided with a first sleeve groove and a second sleeve groove, a connecting hole is provided between the first sleeve groove and the second sleeve groove, the motor and the fixed shaft are respectively located in the first sleeve groove and the second sleeve groove, the output shaft is inserted in the connecting hole, and the output shaft rotates synchronously with the roller; the output shaft and the roller share the same central axis, and the length direction of the handle is perpendicular to the axial direction of the output shaft; this structure is easy to control and easier to use, which helps to improve cleaning efficiency and clean more thoroughly.

[0006] The advantages of an electric cleaning brush are obvious. It greatly improves cleaning efficiency and can clean larger areas in a shorter time than traditional manual cleaning tools. At the same time, its cleaning effect is more thorough and can reach hard-to-reach corners and crevices. In addition, the electric cleaning brush also reduces the user's physical burden, making cleaning easier and more enjoyable.

[0007] Although electric cleaning brushes are popular in the market for their high efficiency and convenience, they also have some disadvantages that cannot be ignored. This is due to the complex structure and sophisticated manufacturing process of electric cleaning brushes. The procurement and assembly costs of core components such as motors and battery packs are not low, which makes the market price of electric cleaning brushes often higher than traditional manual cleaning tools. For consumers with limited budgets, this may become a major obstacle for them to choose electric cleaning brushes. In sharp contrast to its high price, the brush head of the electric cleaning brush is easy to wear out. Since the brush head needs to be in direct contact with the surface to be cleaned, it will inevitably be contaminated and worn during use. The contamination and loss of the brush head will not only affect the cleaning effect, but may also increase the user's maintenance costs. Although some brands provide replaceable brush head designs, frequent replacement of brush heads will also bring additional economic burdens. Summary of the invention

[0041] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are only illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0042] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are directions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0043] like Figure 1 As shown, a handheld electric descaling brush that is convenient for self-cleaning includes an axial brush 100 and a brush body 200 with a brush handle 201. The axial brush 100 is rollably connected to the front end of the brush body 200 in a detachable manner. This design is not only convenient for replacing worn brush heads, but also allows users to select a suitable type of brush head according to cleaning needs. The brush body 200 is composed of a base 1 and a first supporting side wall 2 and a second supporting side wall 3 on both sides, which together form an installation position W for transversely installing the axial brush 100, ensuring the stability of the axial brush 100 and the flexibility of operation.

[0044] like Figure 3 As shown, the shaft brush 100 includes a shaft-shaped support assembly 5 and a metal cleaning mesh sleeve 4 detachably connected to the shaft-shaped support assembly 5. The shaft-shaped support assembly 5 includes a column 51 and a first shaft portion 52 and a second shaft portion 53 located at both ends of the column 51, and the metal cleaning mesh sleeve 4 is tightly sleeved on the column 51. This design not only makes the cleaning mesh sleeve easy to disassemble, clean or replace, avoiding dirt accumulation after long-term use, but also the selection of metal material greatly enhances the durability and cleaning efficiency of the brush head, and is particularly suitable for removing stubborn stains and rust.

[0045] like Figure 1 , 3As shown, the first supporting side wall 2 and the base 1 have an inner cavity connected to each other, in which a motor and a transmission assembly are arranged, the first supporting side wall 2 supports the outer end of the first shaft portion 52, and the motor is connected to the first shaft portion 52 through the transmission assembly. The motor directly drives the first shaft portion 52 through the transmission assembly, thereby driving the entire shaft brush 100 to rotate at a high speed, generating a strong cleaning force, improving work efficiency, and maintaining the stability of operation.

[0046] like Figure 1-4 As shown, the second supporting side wall 3 is hinged with the base 1 so that the second supporting side wall 3 can be closed and opened relative to the base 1. At the same time, a locking assembly 6 is provided between the second supporting side wall 3 and the base 1 to fix the positions of the two in the closed state. The second shaft portion 53 is connected to the second supporting side wall 3 in a shelving manner. When the locking assembly 6 is in a locked state, the second supporting side wall 3 firmly supports the outer end of the second shaft portion 53 to ensure the stability of the shaft brush 100 during use. When the shaft brush 100 needs to be cleaned or replaced, the locking assembly 6 is simply unlocked, and the second supporting side wall 3 can be opened relative to the base 1, so that the mounting position W is fully opened, and the second shaft portion 53 is easily detached from the support. The whole process does not require any tools, which greatly simplifies the maintenance and replacement operations. It should be noted that when the second supporting side wall 3 is opened, one side of the shaft brush 100 is in a free state, so the metal cleaning mesh sleeve 4 can be easily removed from the column 51 or installed on the column 51 through this side. At the same time, the installation position W is in an open state, which is also convenient for deep cleaning of the entire installation position W.

[0047] In the past, when the brush head of the electric cleaning brush was worn or seriously dirty due to long-term use, the user often needed to replace the brush head as a whole, which not only increased the cost of use, but also may lead to waste of resources. However, in this embodiment, we abandoned this traditional practice and adopted a more efficient and economical method-replacing the metal cleaning mesh sleeve 4. Through the design, we can easily remove the metal cleaning mesh sleeve 4 from the axial support assembly 5 for cleaning or replacement. When the mesh sleeve is worn or accumulates too much dirt due to long-term use, the user only needs to buy a new mesh sleeve for replacement without replacing the entire shaft brush 100. This design not only greatly reduces maintenance costs, but also reduces the waste of resources, reflecting the concept of green and environmental protection. The replacement process of the metal cleaning mesh sleeve 4 is also extremely simple. The user only needs to open the second support side wall 3 and peel off the mesh sleeve by hand without professional skills or complicated operations. This design not only improves the user's operating convenience, but also improves the usability and satisfaction of the product.

[0048] Preferably, the two ends of the metal cleaning mesh sleeve 4 are wrapped around the end surface of the column 51, and the two ends of the metal cleaning mesh sleeve 4 have a constriction so that the metal cleaning mesh sleeve 4 is tightly clamped on the column 51. The constriction can be achieved by adjusting the combined position of the two free ends of the constriction line. In a more preferred embodiment, the metal cleaning mesh sleeve 4 is elastic and the two ends are wrapped around the end surface of the column 51, and the two ends of the metal cleaning mesh sleeve 4 have an elastic constriction so that the metal cleaning mesh sleeve 4 is tightly clamped on the column 51.

[0049] like Figure 1 , 3 -4, the locking assembly 6 includes a threaded hole 61 located at the side of the base 1 and a locking member 62 located on the second supporting side wall 3, and the locking member 62 includes an operating portion 621 and a threaded portion 622. The operating portion 621 is located on the outside of the second supporting side wall 3, and the threaded portion 622 passes through the second supporting side wall 3 and is threadedly engaged with the threaded hole 61. The operating portion 621 is designed in the form of a knob, and a gripping portion c protruding from the outer side of the second supporting side wall 3 is provided on it. This design not only improves the comfort and convenience of user operation, but also forms a distinct visual mark, which is convenient for users to quickly identify and operate. An elastic member is provided between the operating portion 621 and the second supporting side wall 3, and the elastic member maintains an outward force on the locking assembly 6. When locking, the user presses the knob inward, and the threaded portion 622 completely extends out of the inner side of the second supporting side wall 3, so as to facilitate threaded connection with the threaded hole 61. The threaded connection method of the locking assembly 6 is not only simple in structure and convenient in operation, but also improves the stability and firmness of the connection. During the connection process, the elastic member always exerts an outward force on the locking assembly 6, and the threaded portion 622 is threadedly engaged with the base 1 to pull the base 1 toward the second supporting side wall 3, so that the structure always maintains a reliable connection. When unlocking, the outward force of the elastic member can also make the unlocking process easier.

[0050] like Figure 2 As shown, the rear edge of the side wall of the base 1 and the rear edge of the upper portion of the second supporting side wall 3 are hinged via a vertical pivot L, so that the second supporting side wall 3 can be unfolded backwards, providing the user with more convenient operating space and viewing angle adjustment.

[0051] like Figure 3As shown, the end of the second shaft portion 53 is in the shape of a cone with a gradually decreasing diameter, and the second supporting side wall 3 is provided with a corresponding tapered hole k, which not only simplifies the connection process, but also enables the second shaft portion 53 and the second supporting side wall 3 to be easily and quickly docked. At the same time, when disassembly is required, the user only needs to apply moderate force to achieve a smooth separation of the two, which greatly improves the convenience and efficiency of operation. Although the connection process is simple, the close fit between the conical end and the tapered hole k ensures the stability of the structure. When subjected to external force, the two can fit tightly together to effectively prevent loosening or falling off, thereby ensuring the stability and safety of the overall structure. In addition, the center of the cone surface is normalized, which makes the rotation axis of the shaft brush 100 more stable, less prone to shaking, and better cleaning efficiency.

[0052] like Figure 3-4 As shown, a positioning recess m is provided on the outer side of the base 1, a positioning boss n is provided on the inner side of the second supporting side wall 3, and the locking assembly 6 is provided between the positioning recess m and the positioning boss n. An arc-shaped concave surface e is provided on the lower side of the base 1, and a convex portion h is provided on the second supporting side wall 3. When the second supporting side wall 3 is closed relative to the base 1, the convex portion h enters under the arc-shaped concave surface e.

[0053] The arcuate convex surface f on the upper surface of the raised portion h is in close contact with the arcuate concave surface e. The ingenious cooperation between the positioning recess m and the positioning boss n, as well as the setting of the locking assembly 6, ensure the precise positioning of the base 1 and the second supporting side wall 3 during connection, and effectively prevent the problem of unstable connection caused by misalignment. At the same time, the positioning cooperation between the raised portion h and the arcuate concave surface e further enhances the stability and position accuracy of the connection. The user can easily achieve the closing and separation of the base 1 and the second supporting side wall 3 during operation, which greatly improves the convenience and efficiency of operation. In addition, the strength of the overall structure is enhanced to a certain extent. This design makes the product more stable and durable when subjected to external forces, and extends its service life.

[0054] like Figure 3-5 As shown, the shaft-shaped support assembly 5 includes a rotating shaft 7 and a support body 8. The support body 8 is detachably mounted on the rotating shaft 7 to form a column 51, and the two ends of the rotating shaft 7 exceed the support body 8 to form a first shaft portion 52 and a second shaft portion 53. After the second support side wall 3 is opened, the support body 8 with the metal cleaning mesh sleeve 4 can be detached from the rotating shaft 7 as a whole, so that the support body 8 can also be cleaned or replaced, which further simplifies the cleaning and maintenance process, improves the cleaning efficiency, and enables the equipment to always maintain the best working state.

[0055] Based on the above, it should be recognized that the shaft brush includes a rotating shaft and a brush body detachably mounted on the rotating shaft; the rotating shaft includes a first shaft portion and a second shaft portion at both ends, and when the second supporting side wall 3 is flipped open, the brush body can be peeled off the rotating shaft as a whole.

[0056] like Figure 4-6 As shown, the support body 8 includes an elastic support portion 81 located on the outer layer, and the elastic support portion 81 provides good support and elasticity, so that the metal cleaning mesh sleeve 4 can be evenly distributed and closely fit the surface to be cleaned. This combination not only enhances the durability and cleaning effect of the brush body, but also improves the adaptability of the brush body, enabling it to cope with surfaces of different hardness and roughness.

[0057] like Figure 2 As shown, the elastic support portion 81 includes a plurality of raised areas and a plurality of recessed areas that are distributed at intervals. The raised areas serve as the supporting structure of the metal cleaning mesh sleeve 4, which promotes the effective distribution of the metal cleaning surface structure and ensures uniform cleaning force. The recessed areas play a key role in sewage and debris removal, effectively collecting and guiding debris and dirt out of the cleaning area to prevent blockage and maintain the long-lasting cleaning performance of the brush body. This concave-convex structure also increases the specific surface area of ​​the action, increases the friction of the cleaning surface, and thus improves the cleaning effect. Preferably, the elastic support portion 81 is made of silicone, and thus has good elastic support and antibacterial and mildew-proof properties.

[0058] like Figure 4-6 As shown, in the preferred technical solution, the elastic support portion 81 includes annular ridges a and annular depressions b spaced apart along the axis, thereby forming a raised area and a depressed area. The alternating appearance of the annular ridges a and the depressions improves the elastic deformation ability of the elastic support portion 81, and also provides additional friction and cleaning effects, which helps to remove deeper stains and impurities, and is also more conducive to sewage discharge. The metal cleaning mesh sleeve 4 is wrapped around the end of the elastic support portion 81 to form an annular portion extending from the outer periphery of the elastic support portion 81, and the metal cleaning mesh sleeve 4 is shrunken, so that the metal cleaning mesh sleeve 4 can be stably connected to the elastic support portion 81 without the need for other structures.

[0059] like Figure 4-6 As shown, the width of the annular ridge a gradually increases from the outside to the inside in the diameter direction to form a ridge shape. The width of the annular ridge a gradually increases from the outside to the inside in the diameter direction. This ridge-shaped design can significantly enhance the stability of the structure. When subjected to external forces, it can more effectively disperse stress and reduce the risk of structural damage caused by stress concentration.

[0060] like Figure 5-6As shown, the support body 8 includes an annular hard portion 82 located in the inner ring, the annular hard portion 82 and the elastic support portion 81 are combined into a whole through a rubber coating process, the annular hard portion 82 is provided with a non-circular shaft hole, and the annular hard portion 82 is circumferentially fixed to the rotating shaft 7. The setting of the annular hard portion 82 not only realizes the synchronous rotation with the rotating shaft 7, but more importantly, avoids the flexible elastic support portion 81 from being directly connected to the rotating shaft 7. Since the elastic support portion 81 is usually relatively soft and easy to wear, direct connection may cause it to be damaged quickly. As a hard component, the annular hard portion 82 can withstand greater pressure and wear, thereby enhancing the stability and durability of the entire structure.

[0061] like Figure 1 As shown, the front surface of the brush body 200 is a slope g that tilts forward from top to bottom, and a lighting component 9 is provided on the slope g above the installation position W. The setting of the lighting component 9 enables the user to easily observe the area to be cleaned without having to find an additional light source or adjust the lighting angle during the cleaning process. This not only simplifies the operation steps, but also improves the convenience of operation and the user's experience.

[0062] Furthermore, if Figure 1 , 6 As shown, the lighting surface y of the lighting component 9 is arranged on a convex block u, and the lighting surface y is perpendicular to the front surface of the brush body 200. The lighting component 9 can irradiate the shaft brush 100 and can irradiate the object to be cleaned in front of the cleaning brush. The lighting surface y of the lighting component 9 can directly irradiate the object to be cleaned in front of the cleaning brush, so that the user can clearly see the specific conditions of the area to be cleaned, such as the distribution of dust and stains. This helps the user to more accurately control the movement trajectory and strength of the cleaning brush, thereby avoiding repeated cleaning or missing cleaning areas, and significantly improving the cleaning efficiency. Through the irradiation of the lighting component 9, the user can more clearly observe the contact between the cleaning brush and the object to be cleaned. This helps the user to promptly discover and adjust the state of the cleaning brush to ensure that the cleaning brush can always maintain the best cleaning effect. Preferably, the upper surface of the brush handle 2013 is provided with a button f for controlling the motor and the lighting component 9.

[0063] like Figure 3 , 7 As shown, a guide plate 10 is detachably provided between the first supporting side wall 2 and the second supporting side wall 3, and the guide plate 10 is inclined from the rear side of the shaft brush 100 to the bottom of the shaft brush 100. The guide plate 10 helps to guide the sewage flow generated by the brush body during the rotation process to flow smoothly downward along the guide plate 10, avoiding the accumulation of sewage around the brush body, thereby improving the cleaning efficiency. Especially in the scene where liquid stains or fine particles need to be removed, this design can more effectively remove stains and particles and reduce cleaning dead corners.

[0064] Preferably, the guide plate 10 is a flexible silicone plate with snap ears t on both sides thereof and corresponding snap holes p on the front wall of the base facing the mounting position W, thereby realizing a detachable snap connection.

[0065] Preferably, the surface of the guide plate 10 facing the shaft brush 100 is an arc surface that is consistent with the bending direction of the shaft brush 100, so that the guide plate 10 can better fit the surface of the brush body, reduce the resistance of the water flow on the contact surface, and improve the diversion effect. At the same time, this design also helps to maintain the stability and balance of the brush body, and reduce the deformation or wear of the brush body caused by uneven force during the cleaning process.

[0066] Furthermore, the guide plate 10 is detachably connected to the brush body 200, so that the user can easily remove the guide plate 10 from the brush body 200 for cleaning or replacement. This not only helps to keep the guide plate 10 clean and sanitary, and prolong its service life, but also facilitates the user to perform deep cleaning and maintenance on the brush body 200, thereby improving the use effect of the entire cleaning device.

[0067] like Figure 3 , 7 As shown, the front end of the guide plate 10 is curled downward and backward to form a curling structure j, which not only helps to increase the strength and rigidity of the guide plate 10, preventing it from being deformed or damaged due to excessive force during the cleaning process, but also provides a certain protection for the brush body, reducing damage to the brush body caused by collision or friction. At the same time, the curling design can guide the sewage to the front end of the guide plate 10 to prevent sewage backflow.

[0068] The above is an introduction to a handheld electric descaling brush that is easy to clean by itself provided by the present invention. The principle and implementation method of the present invention are described in this article using specific examples. The description of the above embodiments is only used to help understand the present invention and its core ideas. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present invention without departing from the principle of the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
