[0040] Below, the embodiments of the present invention are described in detail with reference to the accompanying drawings. In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described in combination with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0041] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the present invention for which protection is sought, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0042] Example 1

[0043] like Figures 1-5 As shown, the magnetic adjustment structure of a double-sided window cleaner provided in this embodiment is mainly composed of a accommodating shell 10, a control component 20 arranged in the accommodating shell 10, a rotation adjustment component 30 transmission-connected to the control component 20, and a magnetic attraction component 40 that cooperates with the rotation adjustment component 30 and has magnetic force. Under the action of external force, the control component 20 can drive the rotation adjustment component 30 to make a rotational motion, and drive the magnetic attraction component 40 to make a vertical motion, thereby adjusting the magnetic distance between the other window cleaner and then adjusting the magnitude of the magnetic attraction force between the two.

[0044] Specifically, the accommodating shell 10 is composed of an upper shell 11 and a lower shell 12 connected to each other. Both can be locked by fasteners such as bolts or fixed by plugging. A groove 111 can be provided in the middle of the upper shell 11 to accommodate part of the control component 20.

[0045] The control component 20 includes an upper cover body 21 provided on the accommodating housing 10, specifically the upper housing 11, a pressing member 22 provided on the inner cavity 211, a clutch member 23 provided inside the pressing member 22, and a second transmission member 24.

[0046] Among them, an inner cavity 211 is provided inside the upper cover body 21, and the position of the inner cavity 211 corresponds to the position of the groove 111 on the upper housing 11. A limiting groove 212 is provided on the inner cavity 211, and a limiting convex block 221 is provided on the pressing member 22. The limiting convex block 221 can only move along the limiting groove 212, ensuring that the pressing member 22 can only perform linear motion rather than rotation inside the inner cavity 211.

[0047] In addition, a rotating groove 231 is incompletely surrounded on the clutch member 23, and the rotating groove 231 is bent. The clutch member 23 is in transmission cooperation with the rotation adjustment component 30. The second transmission member 24 passes through the pressing member 22 and the rotating groove 231. Thus, when the pressing member 22 is acted on by an external force, it can drive the second transmission member 24 to make a vertical movement, and then drive the clutch member 23 to rotate, realizing the switching of the vertical force to the rotational force.

[0048] Among them, a first elastic member 51 is provided between the pressing member 22 and the clutch member 23. The first elastic member 51 is used to provide an elastic force for ejecting the clutch member 23. A second elastic member 52 is provided between the pressing member 22 and the accommodating housing 10. The second elastic member 52 is used to provide an elastic force for resetting the pressing member 22.

[0049] Among them, the rotation adjustment component 30 includes a gear position rotating member 31, a third elastic member 53, and a first transmission member 301. The gear position rotating member 31 is incompletely surrounded with a gear position groove 32. The gear position groove 32 has a plurality of continuous gear position surfaces 321 in different planes. The gear position surfaces 321 are generally in a horizontal state, and two adjacent gear position surfaces 321 are connected by a slope. The first transmission member 301 passes through the magnetic attraction component 40 and the gear position groove 32, and is located on one of the gear position surfaces 321. The magnetic attraction component 40 is sleeved on the gear position rotating member 31 and is connected to the gear position rotating member 31 through the first transmission member 301. The clutch member 23 drives the gear position rotating member 31 to rotate synchronously, and drives the first transmission member 301 and the magnetic attraction component 40 to make a vertical movement along the gear position groove 32, thereby realizing the switching of the rotational force to the vertical force.

[0050] In addition, the third elastic member 53 is provided between the gear position rotating member 31 and the accommodating housing 10, specifically the lower housing 12. The third elastic member 53 is a torsion spring and is used to provide a torsional force for resetting the gear position rotating member 31.

[0051] In addition, a first transmission gear 232 is provided on the lower end surface of the clutch member 23, and a second transmission gear 311 is provided on the upper end surface of the gear rotating member 31. The first transmission gear 232 is in transmission cooperation with the second transmission gear 311, and the two constitute a ratchet tooth cooperation structure.

[0052] In addition, a convex edge 312 is provided at the upper end of the gear rotating member 31. The convex edge 312 semi - surrounds the outside of the second transmission gear 311. Gear position information, such as low, medium, and high gears, is provided on the convex edge 312 and is wound around the outside of the groove 111.

[0053] In addition, the magnetic attraction assembly 40 generally consists of a housing and a magnet inside the housing.

[0054] After assembling conventional components such as cleaning cotton on the magnetic field - adjusting structure of the above window wiper, a window wiper with a window - wiping function can be formed.

[0055] When the present utility model is in use, the two window wipers are butted on the corresponding two sides of the window, and then window scrubbing can be carried out. When the magnetic force needs to be adjusted, the pressing member 22 is pressed down. The pressing member 22 overcomes the elastic force of the second elastic member 52 until the clutch member 23 descends to contact and engage with the tooth part of the gear rotating member 31. Continuing to press down the pressing member 22, the clutch member 23 rotates under the cooperation of the rotating groove 231 and the second transmission member 24, and drives the gear rotating member 31 to rotate. At this time, the first transmission member 301 moves in the gear position groove 32 until the first transmission member 301 drops from the higher gear position surface 321 to the next lower gear position surface 321. The position of the magnetic attraction assembly 40 changes accordingly, that is, one gear shift is completed. At this time, the pressing member 22 is released, and the pressing member 22 rebounds and resets under the action of the second elastic member 52, so that the clutch member 23 is separated from the gear rotating member 31. And because the two window wipers are in an adsorbed state, the generated magnetic attraction force is greater than the reset force of the third elastic member 53, and the gear rotating member 31 cannot rotate back, and the gear position is in a stable state.

[0056] When the two window wipers are separated, due to the absence of magnetic attraction force, the third elastic member 53 drives the gear rotating member 31 to rotate back, driving the first transmission member 301 and the magnetic attraction assembly 40 back to the starting gear position. And in this state, even if the pressing member 22 is pressed down to complete the gear position adjustment and then the pressing member 22 is released, it will also be reset under the action of the third elastic member 53 and return to the starting weakest magnetic force gear, thereby ensuring that the window wiper is in the weakest magnetic force gear when initially used, ensuring the use safety.

[0057] Embodiment 2

[0058] As Figures 6-7As shown, the difference from Embodiment 1 is that the control component 20 is here composed of a twisting member 201 and an upper cover 202. The structure of the upper cover 202 is the same as that of the upper cover body 21 in Embodiment 1. The twisting member 201 is fixedly connected to the gear rotating member 31 here. The twisting member 201 is mainly composed of a knob part and a columnar connecting part. The knob part is exposed for easy twisting, and the connecting part is coaxially fixed with the gear rotating member 31. Thus, by rotating the twisting member 201, the gear rotating member 31 can be driven to rotate synchronously, and then the lifting adjustment of the magnetic attraction component 40 can be realized. When resetting, the twisting member 201 rotates back to its original position along with the gear rotating member 31.
