Description

Technical Field

[0001] This utility model belongs to the field of glass cleaning technology, and in particular relates to a magnetic glass cleaner with anti-pinch function. Background Technology

[0002] Magnetic glass cleaners are a common type of glass cleaner. They generally consist of an inner cleaning body on the inside side of the glass and an outer cleaning body on the outside side. The outer cleaning body contains an external magnet, and the inner cleaning body contains an internal magnet. The external and internal magnets attract each other, thus fixing the two cleaning bodies together. To prevent the magnetic glass cleaner from falling off while cleaning glass, existing magnetic glass cleaners often have a relatively strong attraction between the external and internal magnets. However, when the inner and outer cleaning bodies are magnetically attracted, especially when there is no glass between them, there is a possibility of pinching the user's hand. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a magnetic glass cleaner with a reasonable design, simple structure, and anti-pinch function that can prevent fingers from being pinched.

[0004] A magnetic glass cleaner with anti-pinch function includes two cleaning bodies, each of which contains a magnet. The two cleaning bodies are fixed to each other by mutual attraction of the internal magnets. One of the cleaning bodies contains an anti-pinch mechanism and a switching mechanism.

[0005] The anti-pinch mechanism includes a limiting member and anti-pinch members that are slidably disposed on the left and right sides of the wiping body in a vertical direction. The wiping body has a through hole on its lower side for the anti-pinch members to pass through. At least one first elastic member is provided between the end of the anti-pinch member near the limiting member and the wiping body, which gives the anti-pinch member a tendency to move away from the limiting member.

[0006] The switching mechanism includes an operating component, a transmission structure, and a reset structure. The operating component is slidably disposed on the upper side of the wiping body along the length direction of the wiping body. The two ends of the transmission structure are respectively connected to the operating component and the limiting component. The transmission structure includes a first transmission component and two second transmission components. One end of the first transmission component is connected to the operating component, and the left and right sides of the other end of the first transmission component have driving inclined surfaces. One end of the second transmission component is connected to the limiting component, and the other end of the second transmission component has a driven inclined surface. The driven inclined surfaces of the two second transmission components abut against the driving inclined surface on the left and right sides of the first transmission component, respectively. The reset structure includes two second elastic components disposed along the width direction of the wiping body and causing the second transmission component to have a tendency to move towards the first transmission component. The two ends of the second elastic components abut against the wiping body and the second transmission component, respectively.

[0007] When in the anti-pinch state, the driving inclined surface abuts against the front part of the driven inclined surface, one end of the limiting member abuts against one end of the anti-pinch member, and the other end of the anti-pinch member extends out of the wiping body; when in the cleaning state, the driving inclined surface abuts against the rear part of the driven inclined surface, one end of the limiting member is away from the sliding path of the anti-pinch member, and the other end of the anti-pinch member can slide towards the inside of the wiping body.

[0008] When switched to anti-pinch mode, the other end of the anti-pinch component can press against the other cleaning body, so that the inner sides of the two cleaning bodies will not come into direct contact, thus preventing fingers from being pinched; when switched to cleaning mode, the two cleaning bodies are magnetically attracted to each other through the glass, and the other end of the anti-pinch component can retract into the cleaning body, so as not to affect the cleaning of the glass.

[0009] Preferably, the anti-pinch component includes two anti-pinch posts and a connecting block. The two ends of the connecting block are respectively connected to the two anti-pinch posts. There are two first elastic elements, one end of which abuts against one end of each anti-pinch post. When in the anti-pinch state, one end of the limiting member abuts against the connecting block. By providing the connecting block, the limiting member's action on the anti-pinch component does not affect the first elastic elements. Simultaneously, the limiting member is located in the middle position between the two anti-pinch posts and the two first elastic elements, resulting in a relatively stable action on the anti-pinch component.

[0010] Preferably, the cleaning body has a guide channel located on the sliding path of the anti-pinch component, and a switching opening is provided on one side of the guide channel for the limiting component to pass through; when in the anti-pinch state, the limiting component is located inside the guide channel; when in the cleaning state, the limiting component is located outside the guide channel. The guide channel provides support for the sliding of the anti-pinch component.

[0011] Preferably, the guide channel has a switching plane flush with one end of the switching port on the outer side. When the limiting member switches between the inside and outside of the guide channel, the lower side of the limiting member abuts against a plane, facilitating the switching operation.

[0012] Preferably, the transmission structure is located above the magnet, and the upper surface of the first transmission member is flush with the upper surfaces of the two second transmission members. Incorporating an anti-pinch mechanism only increases the height of the rubbing body by the thickness of one transmission structure, thus saving more space.

[0013] Preferably, the end face of the limiting member connected to the second transmission member is flush with the upper side face of the second transmission member.

[0014] Preferably, the anti-pinch mechanism further includes an anti-pinch plate disposed between the two wiping bodies. The anti-pinch plate includes an anti-pinch body, the upper side of which is flat, and the lower side of the front end of the anti-pinch body has a downward slope to form a wedge shape. The anti-pinch body can be placed between the two wiping bodies to prevent the inner sides of the two wiping bodies from directly contacting each other; when the inner sides of the two wiping bodies accidentally come into direct contact, by aligning the front end of the anti-pinch body with the rear end of the contact position of the two wiping bodies and pressing the rear end of the anti-pinch body, the two wiping bodies in direct contact can be pried apart.

[0015] Preferably, the front end of the anti-pinch body is provided with a left inclined surface and a right inclined surface on its left and right sides, respectively. By providing the left and right inclined surfaces, the cross-section of the front end of the anti-pinch body is further reduced, and the pressure is greater when the same force is applied. When the inner sides of the two rubbing bodies are in direct contact, it is easier to pry open the two rubbing bodies that are in direct contact.

[0016] Preferably, a pressure plate is provided at the rear end of the anti-pinch body, and the projection of the pressure plate on the anti-pinch body along its length direction covers the projection of the anti-pinch body along its length direction. The pressure plate includes a middle plate and two side plates, with each end of the middle plate connected to one end of one of the two side plates, and the angle between the plane of the middle plate and the plane of the two side plates is less than 90°. When the pressure plate is fully inserted between the two abrasive bodies, one end of each of the two side plates abuts against the rear end of the abrasive body. By providing the pressure plate, when the inner sides of the two abrasive bodies are in direct contact, pressing the pressure plate with force, and the projection of the pressure plate on the anti-pinch body along its length direction covering the projection of the anti-pinch body along its length direction, not only is it more convenient for the user to apply force, but it also allows for striking with a hammer or other striking object, thereby increasing the instantaneous force applied to the anti-pinch body and making it easier to pry open the two abrasive bodies that are in direct contact.

[0017] Preferably, the lower side of the anti-pinch body is provided with at least one strip-shaped groove extending along the length direction of the anti-pinch body; the number of strip-shaped grooves is at least two and arranged along the width direction of the anti-pinch body, with reinforcing ribs formed between adjacent strip-shaped grooves. The strip-shaped grooves reduce the area of ​​the lower plane of the anti-pinch body, thereby reducing the contact area between the lower side of the anti-pinch body and the rubbing body, thus reducing a certain amount of friction and reducing the forward resistance of the anti-pinch body; while providing strip-shaped grooves to reduce the contact area between the lower side of the anti-pinch body and the rubbing body, it can also form a reinforcing rib structure to maintain the strength of the anti-pinch body itself as much as possible.

[0018] Compared with existing technologies, the advantages of a magnetic glass cleaner with anti-pinch function are:

[0019] 1. When switched to anti-pinch mode, the other end of the anti-pinch component can press against the other cleaning body, so that the inner sides of the two cleaning bodies will not come into direct contact, thus preventing the hand from being pinched; when switched to cleaning mode, the two cleaning bodies are magnetically attracted to each other through the glass, and the other end of the anti-pinch component can retract into the cleaning body, so as not to affect the cleaning of the glass.

[0020] 2. By setting a connecting block, the limiting component will not affect the first elastic component when it acts on the anti-pinch component. At the same time, the limiting component is located in the middle position between the two anti-pinch posts and the two first elastic components, so it acts relatively smoothly when it acts on the anti-pinch component.

[0021] 3. When the limiting component switches between the inside and outside of the guide channel, the lower side of the limiting component abuts against a flat surface, which facilitates the switching operation;

[0022] 4. Adding an anti-pinch mechanism only increases the height of the wiping body by the thickness of one transmission structure, thus saving more space;

[0023] 5. The anti-pinch body can be placed between two wipers to prevent the inner sides of the two wipers from directly contacting each other; when the inner sides of the two wipers accidentally come into direct contact, the two wipers can be pried apart by aligning the front end of the anti-pinch body with the rear end of the contact position of the two wipers and pressing the rear end of the anti-pinch body.

[0024] 6. By setting the left and right bevels, the cross-section of the front end of the anti-pinch body is further reduced. When the same force is applied, the pressure is greater, and it is easier to pry open the two directly contacting friction bodies when their inner sides are in direct contact.

[0025] 7. By setting a pressure plate, when the inner sides of the two rubbing bodies are in direct contact, the pressure plate is pressed down. The projection of the pressure plate on the anti-pinch body in the length direction covers the projection of the anti-pinch body in the length direction. Therefore, it is not only more convenient for the user to apply force, but also allows hammers and other striking objects to strike, thereby increasing the instantaneous force applied to the anti-pinch body and making it easier to pry open the two rubbing bodies that are in direct contact.

[0026] 8. The strip groove reduces the area of ​​the lower plane of the anti-pinch body, thereby reducing the contact area between the lower side of the anti-pinch body and the rubbing body, thus reducing friction and reducing the forward resistance of the anti-pinch body; while reducing the contact area between the lower side of the anti-pinch body and the rubbing body by setting the strip groove, it can also form a reinforcing rib structure to maintain the strength of the anti-pinch body itself as much as possible.

[0034] To make the technical problems, technical solutions and beneficial effects solved by this utility model clearer, the utility model will be further described below with reference to the accompanying drawings and specific embodiments. However, this utility model is not limited to the described embodiments. On the contrary, this utility model includes all modifications, variations and equivalents that fall within the scope of the appended claims.

[0035] like Figure 1-4 As shown, a magnetic glass cleaner with anti-pinch function includes two cleaning bodies 1, each of which is provided with a magnet 11. The two cleaning bodies 1 are fixed to each other by mutual attraction of the internal magnets 11. One of the cleaning bodies 1 is provided with an anti-pinch mechanism and a switching mechanism.

[0036] The anti-pinch mechanism includes a limiting member 42 and anti-pinch members 41 that are slidably disposed on the left and right sides of the wiping body 1 in a vertical direction. The wiping body 1 has a through hole on the lower side for the anti-pinch members 41 to pass through. At least one first elastic member 43 is provided between the end of the anti-pinch member 41 near the limiting member 42 and the wiping body 1, so that the anti-pinch member 41 has a tendency to move away from the limiting member 42.

[0037] The switching mechanism includes an operating component 51, a transmission structure 6, and a reset structure 52. The length direction of the wiping body 1 is the front-to-back direction of the wiping body 1. The operating component 51 is slidably disposed on the upper side of the wiping body 1 along the length direction of the wiping body 1. The two ends of the transmission structure 6 are respectively connected to the operating component 51 and the limiting component 42. The transmission structure 6 includes a first transmission component 61 and two second transmission components 62. One end of the first transmission component 61 is connected to the operating component 51, and the other end of the first transmission component 61 has driving inclined surfaces 611 on both the left and right sides. One end of the second transmission component 62 is connected to the limiting component 42. The components 42 are connected. The other end of the second transmission component 62 has a driven inclined surface 621. The driven inclined surfaces 621 of the two second transmission components 62 abut against the driving inclined surface 611 on the left and the driving inclined surface 611 on the right of the first transmission component 61, respectively. The width direction of the rubbing body 1 is the left and right direction of the rubbing body 1. The reset structure 52 includes two second elastic members arranged along the width direction of the rubbing body 1 and giving the second transmission component 62 a tendency to move towards the direction close to the first transmission component 61. The two ends of the second elastic members abut against the rubbing body 1 and the second transmission component 62, respectively.

[0038] When in the anti-pinch state, the driving inclined surface 611 abuts against the front part of the driven inclined surface 621, one end of the limiting member 42 abuts against one end of the anti-pinch member 41 and the other end of the anti-pinch member 41 extends out of the wiping body 1; when in the cleaning state, the driving inclined surface 611 abuts against the rear part of the driven inclined surface 621, one end of the limiting member 42 is away from the sliding path of the anti-pinch member 41 and the other end of the anti-pinch member 41 can slide towards the inside of the wiping body 1.

[0039] When switched to the anti-pinch state, the other end of the anti-pinch member 41 can abut against the other cleaning body 1, so that the inner sides of the two cleaning bodies 1 will not directly contact each other, thus preventing the hand from being pinched; when switched to the cleaning state, the two cleaning bodies 1 are magnetically attracted to each other through the glass, and the other end of the anti-pinch member 41 can retract into the cleaning body 1, so as not to affect the cleaning of the glass.

[0040] The anti-pinch component 41 includes two anti-pinch posts 411 and a connecting block 412. Both ends of the connecting block 412 are connected to the two anti-pinch posts 411 respectively. There are two first elastic elements 43, one end of which abuts against one end of an anti-pinch post 411. When in the anti-pinch state, one end of the limiting member 42 abuts against the connecting block 412. By setting the connecting block 412, the limiting member 42 does not affect the first elastic elements 43 when acting on the anti-pinch component 41. Simultaneously, the limiting member 42 is located in the middle position between the two anti-pinch posts 411 and the two first elastic elements 43, resulting in a relatively stable action when acting on the anti-pinch component 41.

[0041] The cleaning body 1 has a guide channel 12 located on the sliding path of the anti-pinch member 41 inside. A switching opening 13 for the limiting member 42 to pass through is opened on one side of the guide channel 12. When in the anti-pinch state, the limiting member 42 is located inside the guide channel 12; when in the cleaning state, the limiting member 42 is located outside the guide channel 12. A switching plane 14, flush with one end of the switching opening 13, is provided on the outer side of the guide channel 12. The guide channel 12 provides support for the sliding of the anti-pinch member 41. When the limiting member 42 switches between inside and outside the guide channel 12, the lower side of the limiting member 42 abuts against a flat surface, facilitating the switching operation.

[0042] The transmission structure 6 is located above the magnet 11, and the upper side of the first transmission member 61 is flush with the upper side of the two second transmission members 62. The end face of the limiting member 42 connected to the second transmission member 62 is flush with the upper side of the second transmission member 62. Setting up an anti-pinch mechanism only increases the height of the rubbing body 1 by the thickness of the transmission structure 6, thus saving more space.

[0043] like Figure 5-6 As shown, the anti-pinch mechanism also includes an anti-pinch plate disposed between the two wiping bodies 1. The anti-pinch plate includes an anti-pinch body 2, the upper side of which is flat, and the lower side of the front end of the anti-pinch body 2 has a downward slope to form a wedge shape. The anti-pinch body 2 can be placed between the two wiping bodies 1 to prevent the inner sides of the two wiping bodies 1 from directly contacting each other; when the inner sides of the two wiping bodies 1 accidentally come into direct contact, by aligning the front end of the anti-pinch body 2 with the rear end of the contact position of the two wiping bodies 1, and pressing the rear end of the anti-pinch body 2, the two wiping bodies 1 that are directly in contact can be pried apart.

[0044] The front end of the anti-pinch body 2 is provided with a left inclined surface 21 and a right inclined surface 22 on the left and right sides, respectively. By setting the left inclined surface 21 and the right inclined surface 22, the cross-section of the front end of the anti-pinch body 2 is further reduced. When the same force is applied, the pressure is greater. When the inner sides of the two rubbing bodies 1 are in direct contact, it is easier to pry open the two rubbing bodies 1 that are in direct contact.

[0045] A pressure plate 3 is provided at the rear end of the anti-pinch body 2. The length direction of the anti-pinch body 2 is the front-to-back direction. The projection of the pressure plate 3 on the length direction of the anti-pinch body 2 covers the projection of the anti-pinch body 2 on the length direction, that is, the upper, lower, left, and right boundaries of the pressure plate 3 all exceed the upper, lower, left, and right boundaries of the anti-pinch body 2. The pressure plate 3 includes a middle plate 32 and two side plates 33. The two ends of the middle plate 32 are respectively connected to one end of the two side plates 33, and the angle between the plane of the middle plate 32 and the plane of the two side plates 33 is less than 90°. When the pressure plate 3 is fully inserted between the two abrasive bodies 1, one end of the two side plates 33 abuts against the rear end of the abrasive body 1. By setting the pressure plate 3, when the inner sides of the two abrasive bodies 1 are in direct contact, pressing the pressure plate 3 with force, and the projection of the pressure plate 3 on the length direction of the anti-pinch body 2 covers the projection of the anti-pinch body 2 on the length direction, it is not only more convenient for the user to apply force, but also allows for striking with hammers or other striking objects, thereby increasing the instantaneous force applied to the anti-pinch body 2, making it easier to pry open the two abrasive bodies 1 that are in direct contact.

[0046] The lower side of the anti-pinch body 2 is provided with at least one strip groove 23 extending along the length direction of the anti-pinch body 2; the number of strip grooves 23 is preferably at least two and arranged along the width direction of the anti-pinch body 2, and a reinforcing rib 24 is formed between adjacent strip grooves 23. The strip grooves 23 reduce the area of ​​the lower plane of the anti-pinch body 2, thereby reducing the contact area between the lower side of the anti-pinch body 2 and the rubbing body 1, thus reducing a certain amount of friction and reducing the forward resistance of the anti-pinch body 2; while setting the strip grooves 23 to reduce the contact area between the lower side of the anti-pinch body 2 and the rubbing body 1, it can also form a reinforcing rib 24 structure to maintain the strength of the anti-pinch body 2 itself as much as possible.

[0047] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0048] Although this document frequently uses terms such as rubbing body 1, magnet 11, guide channel 12, switching port 13, switching plane 14, anti-pinch body 2, left inclined surface 21, right inclined surface 22, strip groove 23, reinforcing rib 24, pressure plate 3, middle plate 32, side plate 33, anti-pinch component 41, anti-pinch column 411, connecting block 412, limiting component 42, first elastic component 43, operating component 51, reset structure 52, transmission structure 6, first transmission component 61, driving inclined surface 611, second transmission component 62, and driven inclined surface 621, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
