Description

A paper towel dispenser capable of preventing paper rolls from collapsing Technical Field

[0001] The present invention relates to the technical field of daily necessities, and in particular to a paper towel dispenser capable of preventing a paper roll from collapsing. Background Art

[0002] A paper towel dispenser is a device for holding paper rolls, which is suitable for use in public places such as kitchens and bathrooms. In order to facilitate use and save space, some center-pull paper towel dispensers have appeared on the market, which can pull out paper towels from the middle of the paper roll. However, the existing paper towel dispensers have the following problems when in use: when a small amount of paper roll is left, the upper part of the paper roll tends to collapse due to gravity and squeeze into a ball, which makes it easy to break or difficult to pull.

[0003] Summary of the Invention

[0004] The object of the present invention is to provide a paper towel dispenser that prevents paper rolls from collapsing, so as to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] The technical solutions adopted to solve the above technical problems are:

[0006] The present invention provides a paper towel dispenser, comprising: a housing and a paper pressing mechanism, wherein the housing comprises a bottom housing and a surface cover arranged on the front side of the bottom housing, wherein the surface cover and the bottom housing constitute a paper loading cavity for placing a paper roll, and wherein the paper loading cavity is provided with a first paper outlet located on the surface cover; and wherein the paper pressing mechanism is provided on at least one of the front inner side and the rear inner side of the paper loading cavity, and wherein the paper pressing mechanism is located above the first paper outlet.

[0007] The beneficial effects of the present invention are:

[0008] When in use, the paper roll is placed vertically in the paper loading cavity, and the rolled paper is drawn out from the first paper outlet on the front side to realize the middle-drawing paper. The present invention uses a paper pressing mechanism to press and fix the upper part of the paper roll in the front-to-back direction to prevent the paper roll from collapsing when a small amount of paper is left. This solves the problem that when a small amount of paper is left in the middle-drawing paper roll, the upper part of the paper roll collapses and squeezes into a ball due to gravity, the weakening of the arch strength of the paper roll due to thinning, or the pulling of the paper roll, which makes the paper roll easy to break or cannot be pulled out.

[0009] As a further improvement of the above technical solution, the paper pressing mechanism includes at least one paper pressing board slidingly arranged on an inner side of the paper loading cavity, and a paper pressing elastic member acting on the paper pressing board. The paper pressing board extends in the up and down directions, and the paper pressing elastic member is used to apply an elastic force to the paper pressing board toward the opposite side of the paper loading cavity.

[0010] This solution uses a paper pressing plate to abut against the upper part of the end surface of the paper roll, and cooperates with the surface cover or bottom shell under the elastic force applied by the paper pressing elastic member to press the paper roll in the front and rear directions. The paper pressing plate extends in the upper and lower directions, which can expand the range of abutment with the paper roll in the upper and lower directions, and can adapt to paper rolls of different outer diameters. The elastic and retractable performance of the paper pressing elastic member can also be used to adapt to paper rolls of different thicknesses.

[0011] As a further improvement of the above technical solution, the paper pressing mechanism also includes a paper pressing sliding groove fixed relatively to the inner wall of the paper loading cavity, the paper pressing paper board is slidably installed in the paper pressing sliding groove, the side wall of the paper pressing sliding groove is provided with a snap-fitting sliding groove, and the side wall of the paper pressing paper board is provided with a snap-fitting sliding groove that is slidably engaged with the snap-fitting sliding groove.

[0012] The paper pressing paper of this solution is installed in the paper pressing sliding groove by sliding forward and backward, and is positioned and installed in the front and back directions by sliding engagement with the snap fastener and the snap-fitting sliding groove. At this time, the elastic force of the paper pressing elastic part can keep pushing the paper pressing paper toward the paper roll, so that the paper pressing paper remains in a compressed state, which is convenient for installation.

[0013] As a further improvement of the above technical solution, the paper pressing elastic member includes at least one curved bow-shaped paper pressing elastic strip, one end of which is connected to the paper pressing board, and the other end of which abuts against the bottom of the paper pressing sliding slot.

[0014] This solution provides elastic pressure to the paper pressing board through a curved bow-shaped paper pressing elastic strip. During production, the paper pressing elastic strip and the paper pressing board are integrally injection-molded, and multiple paper pressing elastic strips can be provided according to the required pressure.

[0015] As a further improvement of the above technical solution, a surface of the paper pressing board facing the opposite side of the paper loading cavity is serrated.

[0016] The paper pressing board of this solution abuts against the end face of the paper roll through a serrated structure. The teeth can extend into the paper roll and clamp the upper part of the paper roll, thereby gripping the paper roll and effectively preventing the upper part of the paper roll from collapsing.

[0017] As a further improvement of the above technical solution, the paper loading cavity is provided with a second paper outlet located at the lower part of the bottom shell, and the second paper outlet is detachably provided with a cover.

[0018] Regarding the paper extraction method, this solution also provides a second paper outlet, which is located at the bottom of the casing. Tissue paper can be pulled out from the second paper outlet to achieve bottom paper extraction. When bottom paper extraction is not needed, the cover can be closed.

[0019] As a further improvement of the above technical solution, a paper support is provided at the lower part of the paper loading cavity, and the paper support includes a paper support plate inclined upward from the back to the front, and a mounting plate connected to the rear end of the paper support plate. The mounting plate is inserted between the cover and the bottom shell, and the cross-section of the paper support plate is arc-shaped.

[0020] When the paper roll is pulled out, the present invention provides a paper support to support the bottom of the paper roll so that the paper roll remains vertically arranged in the paper loading cavity. Specifically, the present invention supports the paper roll by a paper support plate, and the paper support plate arranged upwardly tilted has a reset elastic force in the up and down directions. When the paper roll is loaded, the paper support plate is pressed downward. At this time, the center of the paper roll is close to the first paper outlet. After a period of use, as the paper roll in the middle of the paper roll decreases, the gravity decreases. The paper support plate lifts up the bottom of the paper roll under the action of the reset elastic force to facilitate the paper roll to be pulled out from the first paper outlet. The paper support of the present invention is inserted between the cover and the bottom shell through the mounting plate. When the cover is removed, it can be removed together with the paper support, which is convenient to use.

[0021] As a further improvement of the above technical solution, a brush member is provided on the rear inner side of the paper loading cavity, and the brush member is provided above the first paper outlet.

[0022] This solution also provides a brush member to pierce the upper portion of the rear end surface of the paper roll, which can prevent the paper roll from falling forward when the cover is opened and can also fix the upper portion of the paper roll.

[0023] As a further improvement of the above technical solution, the paper pressing mechanism is arranged on the rear side of the surface cover, and the paper pressing mechanism and the brush member are arranged opposite to each other in front and back.

[0024] During installation, the paper pressing mechanism and the brush member press the upper part of the paper roll relative to each other in front and back. The paper pressing mechanism can press the upper part of the paper roll backward so that the paper roll on the upper part of the paper roll is tightly attached to the brush member.

[0025] As a further improvement of the above technical solution, the surface cover is provided with an openable paper outlet cover, the first paper outlet is provided on the paper outlet cover, and the paper pressing mechanism is provided on the back side of the paper outlet cover.

[0026] When replacing the paper roll, the paper discharge cover can be opened, and then the paper roll can be passed through the first paper discharge port, and then the paper discharge cover can be installed. At the same time, when the paper discharge cover is installed, the paper pressing mechanism follows the paper discharge cover to press the upper part of the paper roll. In addition, the paper pressing mechanism is arranged on the paper discharge cover, which can facilitate maintenance of the paper pressing mechanism. BRIEF DESCRIPTION OF THE DRAWINGS
