[0040] Below, embodiments of the present invention are described in detail with reference to the accompanying drawings. 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 below in conjunction 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, rather than 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 invention claimed for protection, but merely represents selected embodiments of the present invention. All other embodiments obtained by ordinary technicians in the field based on the embodiments of the present invention without making any creative work are within the scope of protection of the present invention.

[0042] Example 1

[0043] like Figure 1-Figure 5 As shown, the magnetic adjustment structure of a double-sided window cleaner provided in the present embodiment is mainly composed of a containing shell 10, a control component 20 arranged in the containing shell 10, a rotation adjustment component 30 transmission-connected to the control component 20, and a magnetic attraction component 40 which cooperates with the rotation adjustment component 30 and has magnetic force. The control component 20 can drive the rotation adjustment component 30 to make a rotational motion under the action of an external force, 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, and the two 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 assembly 20 includes an upper cover 21 disposed on the accommodating shell 10 , specifically, on the upper shell 11 , a pressing member 22 disposed on the inner cavity 211 , a clutch member 23 disposed in the pressing member 22 , and a second transmission member 24 .

[0046] Among them, the upper cover body 21 has an inner cavity 211, the position of the inner cavity 211 corresponds to the position of the groove 111 on the upper shell body 11, and a limiting groove 212 is set on the inner cavity 211. A limiting protrusion 221 is set on the pressing member 22, and the limiting protrusion 221 can only move along the limiting groove 212, ensuring that the pressing member 22 can only move linearly in the inner cavity 211 instead of rotating.

[0047] In addition, a rotation groove 231 is not completely surrounded on the clutch 23, and the rotation groove 231 is bent. The clutch 23 cooperates with the rotation adjustment component 30 in transmission, and the transmission member 24 passes through the pressing member 22 and the rotation groove 231. Therefore, the pressing member 22 can drive the transmission member 24 to move in the vertical direction under the action of external force, and then drive the clutch 23 to rotate, thereby realizing the switching of vertical force to rotational force.

[0048] Among them, an elastic member 51 is arranged between the pressing member 22 and the clutch member 23, and the elastic member 51 is used to provide elastic force to eject the clutch member 23. An elastic member 52 is arranged between the pressing member 22 and the accommodating shell 10, and the elastic member 52 is used to provide elastic force to reset the pressing member 22.

[0049] Among them, the rotation adjustment component 30 includes a gear rotating member 31, an elastic member 353 and a transmission member 301. The gear rotating member 31 is incompletely surrounded by a gear slot 32. The gear slot 32 has multiple continuous gear surfaces 321 in different planes. The gear surfaces 321 are generally horizontal, and two adjacent gear surfaces 321 are connected by a slope. The transmission member 301 passes through the magnetic suction component 40 and the gear slot 32, and is located on one of the gear surfaces 321. The magnetic suction component 40 is sleeved on the gear rotating member 31 and is connected to the gear rotating member 31 through the transmission member 301. The clutch member 23 drives the gear rotating member 31 to rotate synchronously, and drives the transmission member 301 and the magnetic suction component 40 to move vertically along the gear slot 32, thereby realizing the switching of rotational force to vertical force.

[0050] Furthermore, the elastic member 3 53 is disposed between the gear rotating member 31 and the accommodating shell 10 , specifically, the lower shell 12 . The elastic member 3 53 is a torsion spring to provide a torsional force for resetting the gear rotating member 31 .

[0051] Furthermore, a transmission tooth 1 232 is disposed on the lower end surface of the clutch member 23 , and a transmission tooth 2 311 is disposed on the upper end surface of the gear rotating member 31 . The transmission tooth 1 232 and the transmission tooth 2 311 are in transmission cooperation with each other, and the two constitute a ratchet cooperation structure.

[0052] In addition, a convex edge 312 is provided at the upper end of the gear rotating member 31 , and the convex edge 312 half surrounds the outer side of the second transmission tooth 311 . The convex edge 312 is provided with gear information, such as low, medium, and high, and is wound around the outer side of the groove 111 .

[0053] Furthermore, the magnetic attraction assembly 40 is conventionally composed of a shell and a magnet inside the shell.

[0054] The magnetic adjustment structure of the window cleaner mentioned above can constitute a window cleaner with window cleaning function after being assembled with conventional components such as cleaning cotton.

[0055] When the present invention is in use, two window cleaners are docked on the corresponding sides of the window to clean it. When the magnetic force needs to be adjusted, the pressing member 22 is pressed down, and the pressing member 22 overcomes the elastic force of the elastic member 2 52 until the clutch member 23 is lowered to contact and mesh with the teeth of the gear rotating member 31. The pressing member 22 is continued to be pressed down, and the clutch member 23 rotates under the cooperation of the rotating groove 231 and the transmission member 2 24, and drives the gear rotating member 31 to rotate. At this time, the transmission member 1 301 moves in the gear groove 32. Until the transmission member 1 301 falls from the high gear surface 321 to the next lower gear surface 321, the position of the magnetic suction component 40 changes accordingly, that is, a 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 elastic member 2 52, so that the clutch member 23 is separated from the gear rotating member 31. Since the two window wipers are in the adsorption state, the magnetic suction force generated is greater than the reset force of the elastic member 3 53, the gear rotating member 31 cannot rotate, and the gear is in a stable state.

[0056] When the two window cleaners are separated, due to the absence of magnetic attraction, the elastic member three 53 will drive the gear rotating member 31 to rotate, driving the transmission member 1 301 and the magnetic attraction assembly 40 back to the starting gear. In addition, in this state, even after the pressing member 22 is pressed down to complete the gear adjustment, when the pressing member 22 is released, it will also be reset under the action of the elastic member three 53 and return to the starting magnetic weakest gear, thereby ensuring that the window cleaner is in the magnetic weakest gear when it is initially used, ensuring safe use.

[0057] Example 2

[0058] like Figure 6-Figure 7As shown, the difference from Example 1 is that the control component 20 here is composed of a turning piece 201 and an upper cover 202. The structure of the upper cover 202 is consistent with the structure of the upper cover body 21 in Example 1. The turning piece 201 is fixedly connected to the gear rotating piece 31 here. The turning piece 201 is mainly composed of a knob part and a columnar connecting part. The knob part is exposed to the outside for easy twisting, and the connecting part is coaxially fixed with the gear rotating piece 31. Therefore, by rotating the turning piece 201, the gear rotating piece 31 can be driven to rotate synchronously, thereby realizing the lifting and lowering adjustment of the magnetic suction component 40. When resetting, the turning piece 201 rotates with the gear rotating piece 31 to return to its original position.
