Description

Technical Field

[0001] This utility model relates to daily necessities, specifically to a toilet paper roll box with an automatic paper-cutting function. Background Technology

[0002] Toilet paper is a daily necessity, and existing toilet paper dispensers have a relatively simple structure, mostly consisting of an internally perforated box with a paper-pulling opening. When using it, it is often impossible to pull out and tear the paper with one hand, requiring two hands to operate, which is quite inconvenient. In addition, the toilet paper inside the dispensers in public places is often pulled out in large quantities, resulting in a significant waste of toilet paper. While there is a toilet paper roll technology that aims to save paper, its design is complex and costly, hindering its widespread adoption and failing to fundamentally solve the problem of toilet paper waste in restrooms.

The support shaft is installed in the center position inside the shell. The shell is provided with a paper outlet. The paper roll box also includes a paper cutting unit and an eccentric structure.

[0005] The paper-cutting unit includes a limiting groove, a limiting groove mounting plate, a limiting block, and a limiting block mounting base.

[0006] The limiting groove mounting plate is circular and fixed at the center inside the outer shell, with the support shaft located at the center of the limiting block mounting plate. The limiting groove is installed on the edge of the limiting groove mounting plate near its outer circle.

[0007] The limiting block mounting base is annular and fixed to one end of the eccentric structure facing the limiting groove mounting plate. The limiting block is disposed on the limiting block mounting base.

[0008] The eccentric structure is mounted on the support shaft and rotates around the support shaft, driving the limiting block to rotate and thus cooperating with the limiting groove.

[0009] Furthermore, the eccentric structure includes an elliptical outer cylinder, a counterweight, a bearing mounting cylinder, a bearing, and two balance plates;

[0010] The bearing mounting cylinder and the counterweight are both disposed inside the elliptical outer cylinder. The bearing mounting cylinder is located at the center of the inner circle of the elliptical outer cylinder, and the bearing is disposed inside the bearing mounting cylinder.

[0011] The counterweight is located on the major axis of the elliptical outer cylinder, with one end fixed to the inner wall of the elliptical outer cylinder and the other end fixed to the outer wall of the bearing mounting cylinder. The two balance plates are symmetrically arranged on both sides of the counterweight.

[0012] Furthermore, the eccentric structure also includes a return spring, which is disposed on the support shaft and connected to the inner wall of the bearing mounting cylinder.

[0013] Furthermore, the limiting groove is a U-shaped groove.

[0014] Furthermore, the counterweight is a rectangular block, and its length is the same as the length of the elliptical outer cylinder.

[0015] Furthermore, the limiting groove and the limiting groove mounting plate are made of metal.

[0016] Furthermore, the elliptical outer cylinder, counterweight, limiting block, limiting block mounting base, and bearing mounting cylinder are made of engineering plastics.

[0017] Furthermore, the outer casing is made of stainless steel or plastic.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: due to the adoption of the above technical solution, this utility model has the following characteristics: simple structure and low cost; and with the cooperation of the paper cutting unit and the eccentric structure, this utility model can pull paper in both directions without restricting the direction of paper pulling; and each time only about 25-50 cm of paper towel can be pulled out, which does not affect the use and saves paper, reduces waste and saves resources.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 This utility model discloses a paper roll box with an automatic paper cutting function. The paper roll box includes a shell 1 and a support shaft 3. The support shaft 3 is installed in the center position inside the shell 1. The shell 1 is provided with a paper outlet 2. The paper roll box also includes a paper cutting unit 5 and an eccentric structure 4.

[0028] The paper-cutting unit 5 includes a limiting groove 5-2, a limiting groove mounting plate 5-1, a limiting block 5-3, and a limiting block mounting base 5-4.

[0029] The limiting groove mounting plate 5-1 is circular and fixed at the center inside the outer shell 1. The support shaft 3 is located at the center of the limiting block mounting plate 5-1. The limiting groove 5-2 is installed on the edge of the limiting groove mounting plate 5-1 near the outer circle.

[0030] The mounting base of the limiting block 5-3 is annular and is fixed to one end of the eccentric structure 4 facing the mounting plate of the limiting groove 5-1. The limiting block 5-3 is disposed on the mounting base 5-4 of the limiting block.

[0031] The eccentric structure 4 is mounted on the support shaft 3 and rotates around the support shaft 3, driving the limiting block 5-3 to rotate, thereby cooperating with the limiting groove 5-2.

[0032] The eccentric structure 4 includes an elliptical outer cylinder 4-1, a counterweight 4-2, a bearing mounting cylinder 4-5, a bearing 4-4, and two balance plates 4-3;

[0033] The bearing mounting cylinder 4-5 and the counterweight 4-2 are both disposed inside the elliptical outer cylinder 4-1. The bearing mounting cylinder 4-5 is located at the center of the inner circle of the elliptical outer cylinder 4-1, and the bearing 4-4 ​​is disposed inside the bearing mounting cylinder 4-5.

[0034] The counterweight 4-2 is located on the long axis of the elliptical outer cylinder 4-1, with one end fixed to the inner wall of the elliptical outer cylinder 4-1 and the other end fixed to the outer wall of the bearing mounting cylinder 4-5. The two balance plates 4-3 are symmetrically arranged on both sides of the counterweight 4-2.

[0035] like Figure 5 As shown, the eccentric structure 3 also includes a return spring 6, which is disposed on the support shaft 3 and connected to the inner wall of the bearing mounting cylinder 4-5.

[0036] The limiting groove 5-2 is a U-shaped groove.

[0037] The counterweight 4-2 is a rectangular block, and its length is the same as that of the elliptical outer cylinder 4-1.

[0038] The limiting groove 5-2 and the limiting groove mounting plate 5-1 are made of metal.

[0039] The elliptical outer cylinder 4-1 counterweight, limit block 4-2, limit block mounting base 5-4, and bearing mounting cylinder 5-4 are made of engineering plastics.

[0040] The outer casing 1 is made of stainless steel or plastic.

[0041] Working principle: When using the toilet paper saver, first assemble it. The outer shell 1 is fixed to the wall, and the toilet paper roll is installed on the eccentric structure 3. When the toilet paper is pulled at the paper outlet 2, the eccentric structure 3 is rotated together. When the limiting groove 5-2 collides with the limiting block 5-3, the toilet paper roll can no longer rotate, and the roll breaks under force. At this time, about 25-50 cm of toilet paper is pulled out. Then, due to the eccentric structure 3 being affected by the weight, the toilet paper roll reverses back to its original position for the next use.
