Description

TECHNICAL FIELD

[0001] The utility model relates to a glass cleaner, in particular to a double-sided glass cleaner. BACKGROUND

[0002] At present, the magnetic double-sided window cleaner is widely used, which is mainly composed of two wiping cleaners with magnets and other accessories, wherein the one with a hand-held part is the active wiping block, and the other is the passive wiping block. When in use, the active wiping block on the side close to the human body is moved, and the passive wiping block follows the movement to wipe the glass inside and outside. With the popularization of such products, their structure and function are constantly improved. The Chinese utility model patent with the publication number CN2536179Y discloses a magnetic double-sided window cleaner with rollers, which aims to provide a magnetic double-sided window cleaner with small frictional resistance when moving on the glass. The technical solution is that at least one roller that can roll along the movement direction of the active wiping or passive wiping is arranged in the shell. This technology solves the problem of large frictional resistance and falling of the window cleaner on the glass to a certain extent during wiping, but still has some deficiencies: the roller device is fixed on the shell and cannot be detached, and cannot be replaced. During the cleaning of some glass with more dirt, the granular dirt on the surface of the glass is easy to enter the roller device, so that the roller cannot rotate, causing the whole window cleaner to be unable to be used again. SUMMARY

[0003] In order to solve the above problems in the prior art, the utility model aims to provide a double-sided glass cleaner, which can prevent the glass cleaner from falling off due to excessive resistance when moving in any direction, and the replaceable rolling member can prolong the service life of the cleaner.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a double-sided glass cleaner, comprising a main cleaner and a secondary cleaner, the main cleaner and the secondary cleaner each comprising a shell, a scraping strip, a cleaning cloth and a magnet, the shell comprising an inner shell and an outer shell, the shell on the side opposite to the secondary cleaner of the main cleaner being the inner shell, and the part of the shell other than the inner shell being the outer shell, the scraping strip and the cleaning cloth being arranged on the two opposite sides of the inner shell, and the magnet being arranged between the inner shell and the outer shell to enable the main cleaner and the secondary cleaner to be attracted together. A plurality of installation grooves are formed in the inner shell of the main cleaner and the secondary cleaner in correspondence, and a rolling member or a sliding block member is detachably arranged in the installation groove.

[0005] As a limitation of the utility model, the rolling member comprises a mounting bracket adapted to the installation groove, a rolling ball is accommodated at the top of the outward end of the mounting bracket, and the rolling ball protrudes from the surface of the shell.

[0006] As a limitation of the present invention: the rolling element includes a mounting frame adapted to the mounting groove, a roller with a roller shaft is provided on the top of one outward end of the mounting frame, and the roller protrudes from the surface where the housing is located.

[0007] As a limitation of the present invention: the slider includes a mounting frame adapted to the mounting groove, and a curved protrusion integral with the mounting frame is fixedly provided on the top of one outward end of the mounting frame, and the curved protrusion protrudes from the surface where the shell is located.

[0008] As a limitation of the present invention: a limiting protrusion is fixedly provided on the outer surface of the mounting frame, and a limiting groove corresponding to the limiting protrusion is provided in the mounting groove.

[0009] As a limitation of the present invention: the mounting groove is opened at the center of the edge of the inner shell.

[0010] As a limitation of the present invention: a mounting hole protruding outward is fixedly provided on the outwardly facing shell surface of the auxiliary wiper, and a safety rope is detachably connected to the mounting hole.

[0011] As a limitation of the present utility model: a magnetic adjustment device is provided on the main eraser, and the magnetic adjustment device includes an adjustment knob and a threaded rod. A vertical threaded hole is opened on the main eraser, and the threaded rod slides up and down in the threaded hole. The upper end of the threaded rod is threadedly connected to the adjustment knob, and the lower end of the threaded rod is fixedly connected to the magnet in the main eraser. An adjustment space for the magnet to move up and down is provided in the main eraser.

[0012] As a limitation of the present invention: the cleaning cloth is detachably arranged on one side of the inner shell of the main wiper and the auxiliary wiper, and the scraping strip is detachably arranged on the other side of the inner shell of the main wiper and the auxiliary wiper.

[0013] As a limitation of the present invention, a spacer is movably placed between the main wiper and the auxiliary wiper.

[0014] Due to the adoption of the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0015] (1) The rolling element or slider of the utility model is detachable and replaceable.

DETAILED DESCRIPTION

[0028] The preferred embodiment of the present invention will be described below with reference to the accompanying drawings. It should be understood that the double-sided glass cleaner described herein is a preferred embodiment and is only used to illustrate and explain the present invention, and does not constitute a limitation of the present invention.

[0029] Some of the directional terms or positional relationships described in the present invention are based on the directional relationships in the drawings of the present invention specification and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limiting the content protected by the present invention. Example

[0030] This embodiment Figures 1 to 6 The figure shows a double-sided glass cleaner comprising a main wiper 1 and an auxiliary wiper 2. Both the main wiper 1 and the auxiliary wiper 2 comprise a housing, a scraping strip 5, a cleaning cloth 6, and a magnet 7. The housing on the side of the main wiper 1 facing the auxiliary wiper 2 is the inner housing 3, and the outer housing refers to the portion of the housing excluding the inner housing 3. A magnet 7 is disposed between the inner and outer housings to attract the main wiper 1 and the auxiliary wiper 2 together. When not in use, a spacer 10 is movably positioned between the main wiper 1 and the auxiliary wiper 2 to isolate the strong magnet, prevent pinching, and facilitate separation of the main wiper 1 and the auxiliary wiper 2. The spacer 10 is made of non-magnetic material and can be of any shape.

[0031] like Figure 1 As shown, a detachable scraper 5 is provided on the side of the side facing the main scraper 1 and the auxiliary scraper 2. The scraper 5 is used to scrape away excess moisture on the glass. A detachable cleaning cloth 6 is provided on the other side of the side facing the main scraper 1 and the auxiliary scraper 2. The cleaning cloth 6 is used to clean the glass surface after being wetted with water. The cleaning cloth 6 can be any of an absorbent sponge, a scouring pad, or a microfiber cloth. A handle 8 is fixed to the outer shell of the main scraper 1 for holding the cleaner for cleaning.

[0032] like Figure 2 、 Figure 3As shown, the inner housing 3 of the auxiliary cleaning device 2 is provided with a plurality of mounting slots 41. Removable rolling members 4 or sliders are disposed within the mounting slots 41. Both the rolling members 4 and the sliders are designed to reduce the resistance of the cleaning device when wiping the glass, thereby preventing the auxiliary cleaning device 2 from falling off and protecting the inner housing 3 from wear. The rolling members 4 of the present invention have two structural forms. The first type includes a mounting bracket 42 adapted to fit within the mounting slots 41, and a rollable ball 43 accommodated at the top of the outward-facing end of the mounting bracket 42, with the ball 43 protruding from the surface of the housing. The second type includes a mounting bracket 42 adapted to fit within the mounting slots 41, and a roller with a shaft disposed at the top of the outward-facing end of the mounting bracket 42, with the roller protruding from the surface of the housing. The slider structure of the present invention includes a mounting bracket 42 adapted to fit within the mounting slot 41, and a curved protrusion fixed to the top of one outward end of the mounting bracket 42 and integral with the mounting bracket 42. The curved protrusion protrudes above the surface of the housing. Specifically, the portion of the slider structure that contacts the glass does not roll; it is the curved protrusion integrally formed with the mounting bracket 42. The slider structure can also reduce the resistance to movement of the cleaner to a certain extent when in contact with the surface of the glass being wiped, preventing the cleaner from falling off. However, the degree of resistance reduction is limited, so the first or second type of rolling element is preferred. Furthermore, the roller has a single rolling direction, rolling only when the window cleaner moves perpendicular to the axis of rotation. However, during actual use, it often moves in other directions to adjust the position of the cleaner. Therefore, to achieve better practical results, the first type of detachable rolling element is preferred. This embodiment uses the first type of rolling element as an example for illustration. Specifically, in this embodiment, four rolling elements 4 are located at the center of the edge of the rectangular inner housing 3. Correspondingly, the inner housing 3 of the main wiper 1 and the inner housing 3 of the auxiliary wiper 2 have identical structures, with the same number of rolling elements 4 being provided on the inner housing 3 of the main wiper 1. Specifically, a mounting groove 41 is defined on the surface of the inner housing 3. The rolling elements 4 include a mounting bracket 42 that fits within the mounting groove 41 and is completely seated within the mounting groove 41. A rolling ball 43 is secured to the top of the outward-facing end of the mounting bracket 42. The ball 43 is spherical, with a portion protruding from the top of the mounting bracket 42, allowing the ball 43 to roll in any direction on the mounting bracket 42. When the rolling elements 4 are installed, the ball 43 should slightly protrude from the surface of the inner housing 3. This allows the ball 43 to contact and roll with the surface of the glass being wiped, reducing resistance when the cleaner is moved in all directions and preventing it from falling off. Furthermore, the protruding ball 43 provides a degree of protection for the inner housing 3.

[0033] To secure the rolling element 4 in the mounting groove 41 and facilitate its removal and installation, a retaining protrusion 44 is fixed to the mounting bracket 42. A corresponding retaining groove (not shown) is defined within the mounting groove 41. Two retaining protrusions 44 are located near the upper portion of the outer surface of the mounting bracket 42. These protrusions 44 protrude from the outer surface of the mounting bracket 42, with their upper portion protruding larger than their lower portion. Correspondingly, the retaining groove within the mounting groove 41 secures these retaining protrusions 44 in place. When the rolling element 4 needs to be replaced, it is simply removed and replaced with a spare.

[0034] like Figure 4 、 Figure 5 As shown, the main wiper 1 is equipped with a magnetic force adjustment device. The magnetic force adjustment device includes an adjustment knob 11 and a threaded rod 12. A vertical threaded hole 13 is provided in the main wiper 1. The threaded rod 12 slides up and down in the threaded hole 13. The upper end of the threaded rod 12 is threadedly connected to the adjustment knob 11, and the lower end of the threaded rod 12 is fixedly connected to the magnet 7 inside the main wiper 1. The main wiper 1 has an adjustment space for the magnet 7 to move up and down. The magnetic force adjustment device is used to adjust the distance between the magnet 7 and the inner shell 3, thereby changing the magnetic force between the main wiper 1 and the auxiliary wiper 2. When the glass being cleaned is thin, the magnetic force between the main wiper 1 and the auxiliary wiper 2 is too strong. Turning the adjustment knob 11 causes the threaded rod 12 to rotate upward, which in turn drives the magnet 7 upward. The distance between the threaded rod 12 and the adjustment knob 11 is shortened, causing the magnet 7 to move away from the inner shell 3 of the main wiper 1, thereby reducing the magnetic force between the main wiper 1 and the auxiliary wiper 2. When the glass to be cleaned is thicker, the magnetic force between the main wiper 1 and the auxiliary wiper 2 is too small. The adjusting knob 11 is rotated in the opposite direction. The adjusting knob 11 drives the threaded rod 12 to rotate downward, and then drives the magnet 7 to move downward. The distance between the threaded rod 12 and the adjusting knob 11 and the magnet 7 becomes larger, and the magnet 7 moves toward the inner shell 3 of the main wiper 1, thereby increasing the magnetic force between the main wiper 1 and the auxiliary wiper 2.

[0035] like Figure 6As shown, the outer shell of the auxiliary eraser 2 is provided with an outwardly protruding mounting hole 9, into which a safety rope (not shown) is detachably connected. In the prior art, one end of the safety rope is essentially fixed to the auxiliary eraser 2, while the other end can be looped around the arm to prevent the auxiliary eraser from falling. Typically, the safety rope is passed through a relatively small hole that penetrates the outer shell of the auxiliary eraser 2 and is secured by tying a knot in the space between the auxiliary eraser and the inner shell. To replace the safety rope, the auxiliary eraser shell must be fully opened, making this approach quite inconvenient. The mounting hole 9 of the present invention is larger than the safety rope fixing eyelet of the prior art, and is protrudingly fixed on the outer shell of the auxiliary wiper 2, so that the safety rope can be directly disassembled and replaced without opening the shell. Furthermore, in order to make the disassembly and replacement of the safety rope more convenient and the connection between the safety rope and the auxiliary wiper 2 more secure, a connector with an openable and lockable function in the prior art can be used, such as a conventional mountaineering buckle (not shown in the figure). The mountaineering buckle can fix the safety rope to the auxiliary wiper 2 to replace the traditional method of tying knots. This makes it convenient to install and disassemble the safety rope and is strong and durable.

[0036] When using this embodiment, remove the spacer 10 between the main wiper 1 and the auxiliary wiper 2, check whether the scraper 5, cleaning cloth 6, and sliding device 4 are installed in place, soak the cleaning cloth 6, and place the main wiper 1 and auxiliary wiper 2 on the two sides of the glass that has been sprayed with water in advance. The main wiper 1 and auxiliary wiper 2 are adsorbed on the glass by magnetic force. Adjust the adjustment knob 11 until the magnetic force is appropriate. When moving the cleaner, it will neither fall off due to too little magnetic force nor be difficult to move due to too much magnetic force. Finally, move the main wiper 1 back and forth, driving the auxiliary wiper 2 to move together, and complete the cleaning of the glass.
