Description

Technical Field

[0001] The utility model relates to the technical field of cleaning tools, in particular to a window wiper with adjustable magnetic force. Background Art

[0002] Traditional double-sided window wipers rely on magnetic attraction. Wiper plates are respectively arranged inside and outside the glass. Through magnetic attraction, when the inner wiper plate moves, the outer one will move synchronously. The current disadvantages of such double-sided window wipers are as follows:

[0003] 1. Non-adjustable magnetic force: When the magnetic force is small, due to friction, the outer wiper plate is likely to fall off. If the magnetic force is large, it will cause too much friction and increase the labor intensity of cleaning the glass.

[0004] 2. No easy-separation structure: That is, it is rather laborious to open the inner and outer wipers after they are attracted together when not in use. Content of the Utility Model

[0005] To solve the above problems, the utility model provides a window wiper with adjustable magnetic force. The specific technical solution is as follows: It includes an inner wiper and an outer wiper.

[0037] The present utility model will be further described below in conjunction with the accompanying drawings.

[0038] Embodiment 1:

[0039] Referring to Figures 1-11 a window wiper with adjustable magnetic force shown in the figure, which includes an inner wiper 100 and an outer wiper 200. The inner parts of the inner wiper 100 and the outer wiper 200 are respectively provided with a first magnet 101 and a second magnet 201. The first magnet 101 and the second magnet 201 can interact with each other so that the inner wiper 100 and the outer wiper 200 can attract each other to realize synchronous cleaning of the inside and outside of the glass.

[0040] Specifically, the first magnet 101 and the second magnet 201 can be permanent magnets, electromagnets or hybrid magnets, and have appropriate sizes and shapes to form a suitable magnetic field strength and direction. In addition, either the first magnet 101 or the second magnet 201 can be replaced with metallic iron, and the attraction can also be achieved by the attraction of the magnet to the metallic iron. However, this will lead to too high requirements for the magnet. Therefore, it is preferred to use magnets for both.

[0041] In addition, the first magnet 101 and the second magnet 201 are not a single whole magnet, but are composed of a plurality of relatively small magnets. This can avoid magnet breakage and also avoid the concentration of the attraction force at one place. Moreover, in this embodiment, the magnets are fixed by glue bonding.

[0042] In this embodiment, the inner wiper 100 is provided with a glass cleaning surface 102 and an operation surface 103. The glass cleaning surface 102 of the inner wiper 100 is a surface that contacts the glass surface of the window. The operation surface 103 of the inner wiper 100 is an area for operating the window wiper, and there are, for example, buttons, handles or other types of easy-to-operate control devices in the area.

[0043] The interior of the inner wiper 100 is also provided with a base 104. The base 104 is a support structure for mounting the first magnet 101, and the first magnet 101 is dispersedly fixed within the base 104. At the same time, the base 104 is arranged to allow its linear displacement relative to the glass cleaning surface 102. This linear movement can effectively adjust the magnetic attraction force of the first magnet 101. It should be noted that this magnetic attraction force refers to the effective adjustment of the distance between the first magnet 101 and the second magnet 201 through the linear movement of the base 104 in the use state. The smaller the distance, the greater the magnetic attraction force, and vice versa, the larger the distance, the smaller the magnetic attraction force.

[0044] In the inner wiper 100, an adjustment assembly 300 is also provided. This adjustment assembly 300 can be used to control the movement of the base 104, thereby controlling the magnitude of the magnetic attraction force of the first magnet 101. The adjustment assembly 300 can be a manual control device, such as a screw provided on the operation surface 103 of the inner wiper 100. The base 104 is fixed on the screw, and the screw is spirally connected to the inner wiper 100. The linear displacement of the base 104 relative to the glass cleaning surface 102 is controlled by the rotation of the screw. It can also be an electric control, such as setting a motor inside and controlling it with a button. No matter what type the adjustment assembly 300 is, it should be able to precisely control the movement of the base 104 to achieve the best adjustment effect.

[0045] Based on considerations of cost and precise control, the adjustment component 300 in this embodiment is specifically as follows: It includes a knob base 301 provided on the operating surface 103 of the inner wiper 100. This knob base 301 is used as a support structure to accommodate some of the following parts and is also used as a control device like a handle to make the inner wiper 100 easy to operate by hand. A ring-shaped gear ring 302 is fixed on the knob base 301. There are digital markings 302a on the gear ring 302, and elastic buckles 302b are provided at the bottom of the gear ring 302. These elastic buckles 302b can be locked and fixed after being installed in place.

[0046] The adjustment component 300 further includes a knob 303 provided inside the knob base 301, and the knob 303 can rotate within the gear ring 302. There are indication markings 303a on the knob 303, and the digital markings 302a pointed to by these indication markings 303a represent different gears. In addition, there is a stop step 303b at the edge below the knob 303. The part above the stop step 303b is arranged in the middle of the gear ring 302 to limit the rotation of the knob 303 so that the knob 303 can rotate in the middle of the gear ring 302, and this part protrudes from the gear ring 302 for easy operation by hand. The part below the stop step 303b is pressed below by the gear ring 302 to fix the knob 303.

[0047] The adjustment component 300 further includes a stepped ring 304 rotatably installed inside the knob base 301. The knob 303 is in transmission connection with the stepped ring 304. Multiple steps 304a are provided along the circumferential direction on the inner wall of the stepped ring 304. A positioning sleeve 305 is provided inside the stepped ring 304. The positioning sleeve 305 is inserted into the stepped ring 304, and a positioning ear 305a is provided on the outer wall of the positioning sleeve 305. The positioning ear 305a cooperates with the multiple steps 304a on the inner wall of the stepped ring 304. There is a connecting column 104a on the base 104, which is fixed to the positioning sleeve 305.

[0048] When we place the outer window wiper 200 and the inner window wiper 100 on the inside and outside of the window respectively and suck them together, under the action of magnetic attraction, the first magnet 101, the base 104, the connecting column 104a and the positioning sleeve 305 will linearly displace towards the glass cleaning surface 102 of the inner window wiper 100. Then, the positioning ear 305a on the outer wall of the positioning sleeve 305 will be stopped by one of the multi-level steps 304a on the stepped ring 304, so that the position of the first magnet 101 is fixed; when the rotary knob 303 is rotated, the rotary knob 303 will drive the stepped ring 304 to rotate, and the multi-level steps 304a of the stepped ring 304 will also rotate. Since the step heights of the multi-level steps 304a are different and decrease gradually, the stop position of the positioning sleeve 305 will also change. When the rotary knob 303 is rotated step by step, the distance between the first magnet 101 and the second magnet 201 in the outer window wiper 200 will gradually approach, so that the magnetic attraction will gradually increase, thus realizing more precise control without increasing the cost.

[0049] The adjustment assembly 300 is also provided with a reset device for resetting the rotary knob 303 to the initial gear position. The reset device includes a first compression spring 401 disposed inside the connecting column 104a and a torsion spring 402 disposed inside the knob base 301. The first compression spring 401 abuts between the inner wall of the glass cleaning surface 102 and the inner wall of the end of the connecting column 104a. The two ends of the torsion spring 402 are stuck on the first clamping position 303c provided on the rotary knob 303 and the second clamping position 301a on the knob base 301. Under the action of magnetic attraction, the first magnet 101, the base 104, the connecting column 104a and the positioning sleeve 305 will linearly displace towards the glass cleaning surface 102 of the inner window wiper 100, and the rotary knob 303 is rotated, so both the first compression spring 401 and the torsion spring 402 will be deformed; after the window is cleaned or the inner window wiper 100 and the outer window wiper 200 are separated, resulting in the disappearance of magnetic attraction, the reset of the first compression spring 401 will cause the first magnet 101, the base 104, the connecting column 104a and the positioning sleeve 305 to return to their original positions, and the torsion spring 402 will also reset to cause the rotary knob 303 and the stepped ring 304 to rotate back to their original positions.

[0050] Embodiment Two:

[0051] This embodiment is another major improvement of the present invention.

[0052] The improvement of this embodiment lies in:

[0053] Refer to Figures 1-11As shown, a positioning post 500 that can be telescoped relative to the operating surface 103 is provided inside the inner wiper 100. This design can help leave enough space when the inner wiper 100 and the outer wiper 200 are suctioned together, allowing the operator to easily separate the two. After separation, the positioning post 500 can also retract into the operating surface 103 so that the operating surface 103 of the inner wiper 100 can normally contact the surface of the window.

[0054] Specifically, there are four positioning posts 500. Connecting plates 503 are provided between every two of the positioning posts 500. The four positioning posts 500 can be divided into a first positioning post group 501 and a second positioning post group 502. Inside the inner wiper 100, a guide post 600 is provided corresponding to each positioning post 500. The positioning post 500 is sleeved on the guide post 600 and can move along the guide post 600. A second compression spring 700 is sleeved on each guide post 600. Inside the inner wiper 100, a first connecting rod 801 and a second connecting rod 802 are respectively provided in cooperation with the first positioning post group 501 and the second positioning post group 502. A push switch 900 is provided on the operation surface 103 of the inner wiper 100. The push switch 900 forms a sector-shaped flap 901 inside the inner wiper 100. The first connecting rod 801 and the second connecting rod 802 are symmetrically arranged along the flap 901. One end of each of the first connecting rod 801 and the second connecting rod 802 is provided with an inclined piece 804. The two inclined pieces 804 are in contact with the waist position of the flap 901. The other end of each of the first connecting rod 801 and the second connecting rod 802 is provided with a top block 803. The two top blocks 803 are respectively located on the back surface of the connecting plates 503 of the first positioning post group 501 and the second positioning post group 502. Inside the inner wiper 100, a third compression spring 1000 is also respectively provided corresponding to the first connecting rod 801 and the second connecting rod 802; when the window wiper is not in use, the positioning post 500 extends out of the glass cleaning surface 102 of the inner wiper 100. The top blocks 803 are on the back surfaces of the first positioning post group 501 and the second positioning post group 502 to prevent the positioning post 500 from retracting. Therefore, although the inner wiper 100 and the outer wiper 200 are attracted together, the positioning post 500 in the middle can prevent the inner wiper 100 and the outer wiper 200 from being face-to-face, leaving enough space for the operator to easily separate the two. When in use, the push switch 900 on the operation surface 103 uses the flap 901 to push the first connecting rod 801 and the second connecting rod 802 to move to both sides, so that the top blocks 803 leave the back surfaces of the first positioning post group 501 and the second positioning post group 502. At this time, the inner wiper 100 and the outer wiper 200 are attached to the glass surface. The positioning post 500 can retract inside under the action of pressure and magnetic attraction, enabling the window wiper to work properly; it should be noted that after the first connecting rod 801 and the second connecting rod 802 move to both sides, the third compression spring 1000 will be compressed. When the positioning post 500 retracts inside, the second compression spring 700 will be compressed. When the inner wiper 100 leaves the glass surface, under the action of the spring, the positioning post 500, the first connecting rod 801 and the second connecting rod 802 will reset.
