Description

Technical Field

[0001] This utility model relates to the field of cleaning tool technology, and in particular to a magnetic window cleaner. Background Technology

[0002] A double-sided magnetic window cleaner is a window cleaning tool made using the interaction of magnets. Its structure typically includes an inner cleaning body and an outer cleaning body that can be attracted to each other through the glass. Each inner and outer cleaning body is equipped with a magnetic attraction component. When in use, the inner cleaning body is placed on the inner side of the glass and the outer cleaning body is placed on the outer side of the glass. Under the attraction of the magnetic components, when the inner cleaning body is moved, the outer cleaning body will also move accordingly, thus allowing both sides of the glass to be cleaned simultaneously.

[0003] Although double-sided magnetic window cleaners have the advantage of being able to clean both sides of the glass at the same time, the sliding friction between the inner and outer cleaning surfaces and the glass, coupled with the strong magnetic force of the magnetic components, results in significant frictional resistance during cleaning. This makes operation more strenuous and affects cleaning efficiency. Furthermore, the significant frictional resistance makes it difficult for the outer cleaning surface to move synchronously with the inner cleaning surface, increasing the risk of the outer cleaning surface falling off.

[0004] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a magnetic window cleaner with a simple and reasonable structure, easy and labor-saving operation, which helps to improve cleaning efficiency and reduce the risk of windows falling off during cleaning.

[0006] To achieve the above objectives, the present invention adopts the following technical solution.

[0007] A magnetic window cleaner includes an inner window cleaner body and an outer window cleaner body that are adapted to each other. The inner window cleaner body includes an inner window cleaner housing, and an inner magnetic attraction component is disposed within the inner window cleaner housing. The outer window cleaner body includes an outer window cleaner housing, and an outer magnetic attraction component that corresponds to and cooperates with the inner magnetic attraction component is disposed within the outer window cleaner housing. The outer window cleaner housing is provided with an outer ball bearing assembly, and the outer ball bearing assembly includes a plurality of balls arranged in the central region of the outer magnetic attraction component. The balls are rolled relative to the outer window cleaner housing, and a portion of the spherical surface of the balls protrudes from the window cleaner surface of the outer window cleaner housing.

[0008] Furthermore, several of the balls are arranged linearly or radially in the central region of the external magnetic attraction assembly.

[0009] Furthermore, several of the ball bearings are evenly arranged in a straight line or cross shape in the central area of ​​the external magnetic attraction component.

[0010] Furthermore, the outer cleaning window housing is provided with a ball bearing mounting seat inside, and the outer ball bearing assembly also includes a ball bearing limiting seat. The ball bearing limiting seat is connected to the outer cleaning window housing, and an accommodating space for placing the ball bearing is formed between the ball bearing mounting seat and the ball bearing limiting seat. The accommodating space is provided with a plurality of ball grooves corresponding one-to-one with the ball bearing, and the ball bearing limiting seat is provided with a plurality of clearance holes corresponding one-to-one with the ball bearing. Through the clearance holes, a portion of the spherical surface of the ball bearing protrudes from the cleaning surface of the outer cleaning window housing.

[0011] Furthermore, the external magnetic attraction assembly includes a magnet bracket and a plurality of magnets evenly distributed on the magnet bracket with the magnet bracket as the center, and the magnet bracket is provided with a receiving groove corresponding to the ball bearing mounting seat.

[0012] Furthermore, the ball bearing mounting base is integrated with the outer cleaning window housing.

[0013] Furthermore, the outer surface of the ball bearing limiting seat does not protrude from the cleaning surface of the outer cleaning window housing.

[0014] Furthermore, all the balls are arranged with equal diameters.

[0015] Furthermore, the inner magnetic suction component and the outer magnetic suction component are respectively disposed in the central areas of the inner window cleaning housing and the outer window cleaning housing.

[0016] Furthermore, the inner cleaning window housing is provided with an inner ball assembly opposite to the outer ball assembly.

[0017] The beneficial effects of this utility model are as follows: The magnetic window cleaner provided by this utility model, by setting an outer ball bearing assembly on the outer window cleaning housing, arranges the balls of the outer ball bearing assembly in the central area of ​​the outer magnetic attraction assembly, and makes part of the spherical surface of the ball bearing protrude from the window cleaning surface of the outer window cleaning housing. During the window cleaning process, the outer window cleaning body can form a rolling engagement with the glass surface using the balls, thereby reducing the frictional resistance between the outer window cleaning body and the glass. Furthermore, since the balls of the outer ball bearing assembly are located in the central area of ​​the outer magnetic attraction assembly, the magnetic attraction pressure in the area of ​​concentrated magnetic force can be dispersed to the greatest extent, making the outer window cleaning body more responsive, the window cleaning more flexible, the operation less strenuous and convenient, and helping to improve cleaning efficiency and reduce the risk of the outer window cleaning body falling.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] Example 1: As Figures 1 to 4 The magnetic window cleaner shown includes an inner window cleaner body 1 and an outer window cleaner body 2 that are adapted to each other. The inner window cleaner body 1 includes an inner window cleaner housing 11, and an inner magnetic attraction component is disposed within the inner window cleaner housing 11. The outer window cleaner body 2 includes an outer window cleaner housing 21, and an outer magnetic attraction component 22 that corresponds to and cooperates with the inner magnetic attraction component is disposed within the outer window cleaner housing 21. In this embodiment, in order to improve the mutual magnetic attraction effect between the inner window cleaner body 1 and the outer window cleaner body 2, the inner magnetic attraction component and the outer magnetic attraction component 22 are respectively disposed in the central regions of the inner window cleaner housing 11 and the outer window cleaner housing 21. The working principle of the magnetic window cleaner provided in this embodiment is the same as that of the existing double-sided magnetic window cleaner, and will not be described in detail here.

[0025] In this embodiment, see Figures 2 to 4 The outer window cleaning housing 21 is provided with an outer ball bearing assembly 23, which includes a plurality of balls 231 arranged in the central region of the outer magnetic suction assembly 22. The balls 231 are rolled relative to the outer window cleaning housing 21, and a portion of the spherical surface of the balls 231 protrudes from the window cleaning surface 24 of the outer window cleaning housing 21. The surface of the outer window cleaning housing 21 near the glass 3 is the window cleaning surface 24.

[0026] The magnetic window cleaner provided in this embodiment, by setting an outer ball bearing assembly 23 on the outer window cleaning housing 21, arranges the balls 231 of the outer ball bearing assembly 23 in the central region of the outer magnetic attraction assembly 22, and makes part of the spherical surface of the balls 231 protrude from the window cleaning surface 24 of the outer window cleaning housing 21, during the window cleaning process, the outer window body 2 can form a rolling engagement with the surface of the glass 3 using the balls 231, thereby reducing the frictional resistance between the outer window body 2 and the glass 3. Furthermore, for a double-sided magnetic window cleaner, due to its magnetic force concentration area... The area is located in the central region of the inner magnetic attraction component and the outer magnetic attraction component 22. That is, the surface of the glass 3 is subjected to the greatest pressure in the area where the magnetic force is concentrated. In this invention, the ball 231 of the outer ball component 23 is set in the central region of the outer magnetic attraction component 22. Compared with setting the ball 231 in other regions, this invention can disperse the magnetic attraction pressure in the area where the magnetic force is concentrated to the greatest extent, so that the outer cleaning window 2 has better follow-up, the window cleaning is more flexible, the operation is labor-saving and convenient, which is conducive to improving cleaning efficiency and reducing the risk of the outer cleaning window 2 falling off.

[0027] Preferably, to make the magnetic attraction pressure more uniform, a plurality of balls 231 are linearly arranged in the central region of the outer magnetic attraction component 22. Specifically, in this embodiment, see Figure 2 As shown, a number of balls 231 are evenly arranged in a straight line in the central area of ​​the outer magnetic component 22. Of course, as an equivalent alternative, in other embodiments, depending on the specifications or application scenario of the magnetic window cleaner, the number of balls 231 can also be arranged radially in the central area of ​​the outer magnetic component 22, for example, the balls 231 can be evenly arranged in a cross shape in the central area of ​​the outer magnetic component 22.

[0028] Further, see Figures 2 to 4 As shown, in order to facilitate the installation of the ball bearing 231 and improve the positional accuracy of the ball bearing 231, a ball bearing mounting seat 25 is provided inside the outer cleaning window housing 21. The outer ball bearing assembly 23 also includes a ball bearing limiting seat 232. The ball bearing limiting seat 232 is connected to the outer cleaning window housing 21. A receiving space 233 for placing the ball bearing 231 is formed between the ball bearing mounting seat 25 and the ball bearing limiting seat 232. A plurality of ball grooves 234 corresponding to the ball bearing 231 are provided in the receiving space 233. The ball bearing limiting seat 232 is provided with a plurality of clearance holes 235 corresponding to the ball bearing 231. The diameter of the clearance holes 235 is smaller than the diameter of the ball bearing 231. Through the clearance holes 235, part of the spherical surface of the ball bearing 231 protrudes out of the cleaning window surface 24 of the outer cleaning window housing 21.

[0029] Preferably, see Figure 3 and Figure 4As shown, the external magnetic suction assembly 22 includes a magnet bracket 221 and a plurality of magnets 222 evenly distributed on the magnet bracket 221 with the magnet bracket 221 as the center. In this embodiment, the plurality of magnets 222 are evenly distributed around the periphery of the magnet bracket 221. The magnet bracket 221 is provided with a receiving groove 223 corresponding to the ball bearing mounting seat 25. By providing the receiving groove 223, the ball bearing mounting seat 25 is accommodated therein, which can reduce the thickness of the external window cleaning housing 21 and make the overall design of the magnetic window cleaner thinner and lighter.

[0030] Furthermore, for ease of processing, the ball bearing mounting base 25 is integrated with the outer cleaning window housing 21. Specifically, in this embodiment, the outer cleaning window housing 21 and the ball bearing mounting base 25 are integrally injection molded, which can reduce production costs and improve the assembly accuracy of the ball bearing 231.

[0031] Preferably, the outer surface of the ball bearing limit seat 232 does not protrude from the window cleaning surface 24 of the outer window cleaning housing 21, thereby reducing the distance between the outer window cleaning housing 21 and the glass and ensuring the magnetic attraction effect.

[0032] Preferably, all the balls 231 are arranged with the same diameter. By using balls 231 of the same diameter, the balls 231 protruding from the spherical surface of the outer cleaning window housing 21 can form a coplanar plane, thereby making the magnetic attraction pressure on the glass surface more uniform and further improving the flexibility of operation.

[0033] Example 2: See Figures 1 to 4 As shown, the magnetic window cleaner provided in this embodiment has the same main structure and working principle as the one described in Embodiment 1 above. The difference is that in this embodiment, the inner window cleaning housing 11 is provided with an inner ball assembly (not shown in the figure) opposite to the outer ball assembly 23. By configuring the inner ball assembly, the friction between the inner window cleaning body 1 and the glass surface is reduced, which can further improve the operational flexibility. It should be noted that in implementation, the structure of the inner ball assembly in this embodiment can refer to the outer ball assembly 23, so it will not be described in detail here.

[0034] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
