Technical Field

[0001] The utility model relates to the technical field of hair removal devices, in particular to an inclined tearing type labor-saving roller. Background Technique

[0002] The sticky paper inclined tearing type hair removal device is a tool for removing hair, dust and other fine particles on the surfaces of clothes and furniture. Its function is to adhere impurities such as hair to it through the stickiness of the sticky paper, so as to achieve the cleaning effect. The structure of this kind of hair removal device is relatively simple but very practical. It usually consists of a handle and a replaceable sticky paper roll. The handle part is usually made of plastic or metal, with a comfortable hand feeling and easy to hold. The sticky paper roll is a special sticky paper that can firmly adhere hair and dust to it. This kind of sticky paper usually adopts an inclined tearing type design, which is convenient for users to replace and tear off the used part;

[0003] For example, a roller hair removal device disclosed in the authorized publication number CN214458906U includes a hair removal roller, an outer shell and a handle. The hair removal roller is rotatably installed in the outer shell. A first handle connection port is opened at the end of the outer shell, and a handle connection head is also provided in the middle of the outer shell. A second handle connection port is opened on the handle connection head. The handle can be respectively connected with the first handle connection port and the second handle connection port. It has two usage methods, and the handle is convenient to install and disassemble, stable and reliable. However, in this technical solution, the connection part between the outer shell and the handle is a hard connection. When the hair removal roller rolls, it can only move in a straight line, and it is difficult to change the direction or turn without lifting itself. During its use, it is difficult to flexibly adjust the angles or positions of the handle and the hair removal roller, which causes inconvenience when cleaning surfaces of different shapes or angles. For example, when cleaning the surface of furniture, due to the design of the furniture, there may be some uneven places, and the straight-rolling hair removal roller may not be able to completely fit the surface, resulting in some hair or dust not being completely cleaned.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-5 , an embodiment provided by the present utility model: an inclined paper tearing labor-saving roller, including a handle 1 and a front U-shaped seat 2 fixed to one end of the handle 1. The outer peripheral surface of the handle 1 is provided with a helically wound anti-slip groove. The inside of the front U-shaped seat 2 is provided with a cross-axis four-way yaw structure 3, and both sides of the cross-axis four-way yaw structure 3 are provided with Z-shaped connecting plates 4. An inclined paper tearing roller 6 is installed between the two Z-shaped connecting plates 4 through a bolted rotary structure. The bolted rotary structure is used to connect the Z-shaped connecting plates 4 and the inclined paper tearing roller 6. The tops of the two Z-shaped connecting plates 4 are jointly fixed with a cylinder cover 5;

[0021] The bolted rotary structure includes an internal thread counterbore 401 provided on the outer wall of one side of the Z-shaped connecting plate 4, and an external thread pin shaft 402 installed inside the internal thread counterbore 401. Internal thread holes are provided on the outer plane walls of both sides of the inclined paper tearing roller 6. When installing the Z-shaped connecting plate 4 and the inclined paper tearing roller 6, the staff screws the external thread pin shaft 402 into the internal thread counterbore 401 and the inside of the inclined paper tearing roller 6. At this time, the inclined paper tearing roller 6 needs to be in a fixed state to facilitate the external thread pin shaft 402 to be tightened in place. At this time, when the inclined paper tearing roller 6 rotates, it rotates around the external thread pin shaft 402 as the central axis;

[0022] The cross-axis four-way yaw structure 3 includes a square rotating block 301 rotatably installed inside the front U-shaped seat 2, and rotating shafts 302 rotatably installed on the outer walls on both sides of the square rotating block 301. The Z-shaped connecting plate 4 is fixed to the rotating shafts 302. When adjusting the rolling angle of the inclined paper tearing roller 6, the handle 1 deflects up and down through the front U-shaped seat 2 and the rotating shafts 302 together with the Z-shaped connecting plate 4 to adjust the angle between the handle 1 and the inclined paper tearing roller 6. The square rotating block 301 rotates relative to the front U-shaped seat 2 to adjust the left and right yaw structure of the Z-shaped connecting plate 4 and the inclined paper tearing roller 6, and it performs four-way yaw, which makes the user more comfortable and at ease during use. Whether cleaning the surface of furniture, the corners of clothes or the fine dust inside the car, the user can easily adjust the angle of the lint remover to better meet different cleaning needs;

[0023] On the inner wall of the side of the front U-shaped seat 2 close to the handle 1, there are two symmetric yaw centering and resetting structures 7. The movable end of the yaw centering and resetting structure 7 is in contact with the outer wall of one side of the square rotating block 301. The yaw centering and resetting structure 7 includes a C-shaped seat 701 fixed to the inner wall of one side of the front U-shaped seat 2, and a short shaft 702 rotatably installed inside the C-shaped seat 701. An inclined triangular block 703 is fixed to the outer peripheral surface of the short shaft 702. A torsion spring 704 is installed on the outer peripheral surface of the short shaft 702 on one side of the inclined triangular block 703. Two symmetric rubber wheels are installed at the top of the inclined triangular block 703. The top of the inclined triangular block 703 is in contact with the outer wall of one side of the square rotating block 301 through the rubber wheels;

[0024] After the inclined paper tearing roller 6 and the Z-shaped connecting plate 4 yaw, and when the user no longer applies force to the inclined paper tearing roller 6, the two yaw centering and resetting structures 7 can force the square rotating block 301 to automatically center, realizing the function of automatically resetting after the Z-shaped connecting plate 4 and the inclined paper tearing roller 6 yaw; when the square rotating block 301 and the Z-shaped connecting plate 4 yaw left and right, the inclined triangular block 703 yaws with the short shaft 702 as the center, and the torsion spring 704 is in a compressed state. When the inclined paper tearing roller 6 is no longer subjected to force, the torsion spring 704 begins to deform and reset, thereby using the inclined triangular block 703 to push the square rotating block 301 to make the square rotating block 301 reset.

[0025] When the embodiment of the present application is in use, first, the user takes out the inclined paper tearing roller 6, places it in the cylinder cover 5, and uses the bolted rotary structure to connect the Z-shaped connecting plate 4 and the inclined paper tearing roller 6, thus completing the assembly work of the inclined paper tearing roller 6 and the Z-shaped connecting plate 4. At this time, the user can hold the handle 1 and press the inclined paper tearing roller 6 against the surface to be defurred. Then the user pushes the handle 1, the Z-shaped connecting plate 4, and the inclined paper tearing roller 6 to move, and the inclined paper tearing roller 6 firmly adheres the hair and dust to its own surface. The inclined adhesive paper is usually designed in an inclined tearing manner, which is convenient for the user to replace and tear off the used part. During this process, the user can manually deflect the handle 1, so that the cylinder cover 5 swings left and right with the cross-axis four-way swing structure 3 as the center. When the user swings the handle 1 up and down, the angle between the handle 1 and the inclined paper tearing roller 6 can also be adjusted. By adding the front U-shaped seat 2 and the cross-axis four-way swing structure 3 at the end of the handle 1, the inclined paper tearing roller 6 can rotate flexibly in four directions, namely left and right and up and down. This means that when cleaning surfaces of different shapes and angles, the user can more flexibly adjust the angle and position of the roller, no longer limited by the straight-line movement, so as to better fit the surface and improve the cleaning effect. Whether it is cleaning the uneven parts on the furniture surface or the fine dust in narrow spaces, it can be completed more easily.

[0026] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
