Detailed Implementation

[0017] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0018] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the figures only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0019] Example 1: like Figures 1-4As shown, a paper dispensing structure for a wall-mounted tissue box includes a frame, a paper feeding device 2, a control device, and a paper cutting component 3. The control device uses an existing control circuit board and is not shown in the attached drawing. The paper feeding device 2 includes a first paper feeding tube 21, a second paper feeding tube 22, and a power component 23. The first paper feeding tube 21 and the second paper feeding tube 22 are rotatably and adjacently arranged on the frame, and the first paper feeding tube 21 is also connected to the power component 23. In this example, the first paper feeding tube 21 drives the tissue to be transported to the area between the first paper feeding tube 21 and the second paper feeding tube 22. The power component 23 is fixedly mounted on the frame and is electrically connected to the control device fixedly mounted on the frame. The frame is also equipped with a paper outlet hole that runs vertically through the paper. The gap between the first paper feed tube 21 and the second paper feed tube 22 corresponds to the paper outlet hole, which facilitates the feeding of tissues that have passed through the first paper feed tube 21 and the second paper feed tube 22 out of the tissue box. The paper cutter 3 includes a serrated blade, which is fixedly set on one side edge below the paper outlet hole on the frame. It should be noted that the serrated blade is located on the side edge of the paper outlet hole away from the wall where it is mounted, and the serrations on the serrated blade face inwards from the paper outlet hole. In this way, after the user in front of the tissue box has obtained enough tissues, he or she only needs to pull the tissues outwards, and the tissues will come into contact with the serrated blade, which is also located on the outside of the paper outlet hole, making it easy to tear the tissues.

[0020] The frame is horizontally arranged, and the axes of the first paper feeding tube 21 and the second paper feeding tube 22 on the frame are both located in the horizontal direction. There is a set height difference between the axes of the first paper feeding tube 21 and the second paper feeding tube 22. The axis of the first paper feeding tube 21, which is connected to the power component 23, is higher than the axis of the second paper feeding tube 22. In this way, the paper towels fed from top to bottom will first come into contact with the first paper feeding tube 21 located above, which is convenient for feeding into the area between the first paper feeding tube 21 and the second paper feeding tube 22.

[0021] The power component 23 is a motor, which is connected to the first paper feeding tube 21 by gear transmission, including a first gear, a second gear and a third gear. The second gear is rotatably mounted on the frame and meshes with the first gear fixed on the motor and the third gear fixed on the first paper feeding tube 21 to achieve transmission. It should be noted that in this example, the number of teeth of the first gear is much smaller than the number of teeth of the second gear to achieve a speed reduction effect and prevent the first paper feeding tube 21 from rotating too fast.

[0022] The paper feeding device 2 also includes a counting disk 24 and a photoelectric sensor 25. The counting disk 24 is fixedly disposed at one end of the first paper feeding tube 21. Several petal-shaped markers are disposed on the edge of the counting disk 24. The photoelectric sensor 25 is fixedly disposed on the frame. When the counting disk 24 rotates, the markers pass through the sensing area of ​​the photoelectric sensor 25 in sequence to estimate the paper feeding length, so as to limit the paper feeding length at one time and avoid waste.

[0023] The frame is provided with a square paper outlet hole that penetrates the frame. The first paper feed tube 21 and the second paper feed tube 22 are both located inside the paper outlet hole. The two ends of the first paper feed tube 21 are respectively supported on the frame on both sides of the paper outlet hole, and are slidably engaged with the frame to avoid affecting the rotation of the first paper feed tube 21 and the second paper feed tube 22. The two ends of the second paper feed tube 22 are also supported on the frame on both sides of the paper outlet hole. Cover plates 11 are also fixedly provided on the frame corresponding to the two ends of the first paper feed tube 21 and the second paper feed tube 22. The cover plates 11 clamp the ends of the first paper feed tube 21 and the second paper feed tube 22 onto the frame, restricting the rotation of the first paper feed tube 21 and the second paper feed tube 22 within a certain range of motion. After the cover plate 11 is connected to the frame, the protruding part of the second paper feed tube 22 is set as an elongated hole 12. The second paper feed tube 22 can slide along the elongated hole 12 away from the first paper feed tube 21 to adjust the distance between the second paper feed tube 22 and the first paper feed tube 21. Tension springs 27 are also provided between the two ends of the second paper feed tube 22 and the two ends of the first paper feed tube 21, respectively. The tension springs 27 pull the second paper feed tube 22 towards the first paper feed tube 21, so that the two are kept in close contact without external force, clamping the paper towel passing between them, increasing the friction between the paper towel and the paper feed tube, and preventing the paper towel from not being fed. Inside the paper outlet, on both sides corresponding to the axis of the paper feed tube, there are support blocks 13 protruding into the paper outlet; the support blocks 13 support and abut against the bottom of the first paper feed tube 21 and the second paper feed tube 22 respectively, and slide with the paper feed tube; it should be noted that the support blocks 13 on both sides are not merged together, but leave a gap for the paper towel to pass through; the end of the support block 13 is also provided with a slope for guiding the paper towel. In this example, the slope is located on the support block 13 below the second paper feed tube 22, and the slope is inclined from the second paper feed tube 22 to the first paper feed tube 21 in the downward direction.

[0024] The first paper feed tube 21 and the second paper feed tube 22 are also provided with friction sleeves 28 to enhance the coefficient of friction. The friction sleeves 28 can be rubber sleeves with patterns on their outer periphery. The friction sleeves 28 are respectively fitted on the outer periphery of the first paper feed tube 21 and the second paper feed tube 22. It should be noted that the friction sleeves 28 do not contact the support blocks 13 on the frame. That is to say, the friction sleeves 28 are located in the areas on both sides of the support blocks 13 to avoid affecting the rotation of the first paper feed tube 21 and the second paper feed tube 22.

[0025] It should be noted that in this embodiment, the control device can control the paper feeding device 2 to start or stop in the manner of existing switch control or infrared sensing control.

[0026] The above description is merely a specific example of this utility model and does not constitute any limitation on this utility model. Obviously, those skilled in the art, after understanding the content and principle of this utility model, may make various modifications and changes in form and details without departing from the principle and structure of this utility model. However, these modifications and changes based on the concept of this utility model are still within the protection scope of the claims of this utility model.
