Abstract
Description
Technical Field
[0001] This utility model belongs to the field of static electricity elimination technology, specifically the addition of a static electricity elimination device to a pull-out paper dispenser. Background Technology
[0002] In the production of modern household paper products, tissue paper dispensers are common equipment widely used in the manufacture of tissues in homes and public places. However, during the actual operation of these dispensers, static electricity is easily generated due to the frequent friction between the paper and the equipment components during high-speed transport and cutting. The accumulation of static electricity not only causes paper to adhere to the equipment surface, affecting normal transport and cutting efficiency, but can also lead to problems such as paper sticking and uneven stacking, thereby reducing product quality and production efficiency. Furthermore, the presence of static electricity can cause discomfort to operators and even pose safety hazards in certain environments.
[0003] Currently, most tissue paper dispensers are not equipped with dedicated static electricity elimination devices, or only use simple grounding measures to alleviate static electricity problems. However, these methods have limited effectiveness, especially in dry environments or at high production speeds, where they struggle to effectively eliminate the adverse effects of static electricity. Therefore, how to efficiently and reliably eliminate static electricity in tissue paper dispensers has become a pressing technical challenge. Developing devices that specifically address static electricity issues is of great significance for improving equipment operational stability, enhancing product quality, and optimizing the operating environment. Utility Model Content
[0004] This utility model provides a static elimination device for adding an electrostatic discharge (SED) device to a pull-out tissue dispenser, addressing the problem of static electricity adsorption caused by friction during use, which leads to inconvenience for users and hygiene concerns. The SED device for the pull-out tissue dispenser includes a main body and an SED mechanism. The SED mechanism includes a conductive brush assembly and an ion generator. The conductive brush assembly is horizontally positioned within the main body. The bristles of the conductive brush assembly extend outward in a spiral pattern, forming a first conductive groove and a first conductive protrusion on its inner side. The first conductive groove is an inward recess of the inner wall of the conductive brush assembly, and the first conductive protrusion is an outward protrusion of the inner wall of the conductive brush assembly. The first conductive groove and the first conductive protrusion are staggered. Multiple conductive holes are formed on the bristles of the conductive brush assembly. The ion generator is vertically positioned and rotatably mounted within the conductive brush assembly. The outer wall of the ion generator extends outward in a spiral pattern, forming a second conductive protrusion and a second conductive groove on its outer side. The second conductive groove is an inward recess of the outer wall of the ion generator, while the second conductive protrusion is an outward protrusion. The second conductive groove and the second conductive protrusion are staggered. The ion generator and the conductive brush assembly are spirally engaged, with the second conductive protrusion positioned at the first conductive groove. Multiple ion release holes are formed on the outer wall of the ion generator. A conductive sheet is fixedly mounted on the second conductive protrusion, abutting against the first conductive groove. The main body contains an electrostatic elimination chamber and a collection chamber. The electrostatic elimination chamber is located above the collection chamber, and the conductive brush assembly is positioned within the electrostatic elimination chamber. A first vent is also provided within the main body, connecting the electrostatic elimination chamber and the collection chamber. The electrostatic elimination mechanism also includes a lower pressure plate, which slides vertically within the collection chamber. Initially, the lower pressure plate blocks the first vent. A spring is installed inside the collection chamber, connecting the main body and the lower pressure plate. A connecting rod is fixedly installed at the lower part of the ion generator, the connecting rod is vertically arranged, and communicates with the ion generator. The lower end of the connecting rod is used to abut against the upper surface of the lower pressure plate. The tissue dispenser also includes a drive mechanism, which includes a rotating shaft and a handle. The rotating shaft is vertically arranged inside the main body and can rotate around its own axis. The rotating shaft is located inside the connecting rod, which can rotate synchronously with the rotating shaft and can move up and down relative to the rotating shaft. The handle is fixedly connected to the lower end of the rotating shaft and is located outside the main body. The rotating shaft and the connecting rod are splined together. At least one dust discharge port is provided at the bottom of the main body, communicating with the collection chamber. A sealing cover is provided at the lower end of the main body, threadedly connected to the main body, and used to seal the dust discharge port. An air inlet and an air outlet are provided on the main body, both communicating with the electrostatic elimination chamber, with the air inlet located above the conductive brush assembly. The ion generator has at least one second vent hole at its bottom, and a one-way valve is installed inside the second vent hole. The one-way valve allows airflow to flow unidirectionally from the bottom of the ion generator into the conductive brush assembly. The diameter of the conductive hole is smaller than the diameter of the ion release hole.
[0005] The beneficial effects of this invention are as follows: Through the conductive brush assembly and ion generator, the static electricity generated during the operation of the tissue dispenser is introduced into the ion generator via the conductive brush assembly. The ion generator releases negative ions to neutralize the static electricity before discharging it outside the main body. Due to the first conductive groove and the first conductive protrusion on the conductive brush assembly, during static electricity conduction, the static charge is mainly concentrated in the recessed area of the impact surface, i.e., the static charge is mainly concentrated in the first conductive groove, while static electricity residue is less likely to accumulate at the first conductive protrusion. This improves the static electricity conduction efficiency of the conductive brush assembly to a certain extent. After the static electricity has been eliminated for a period of time, the ion generator is rotated. The ion generator rotates and moves up and down relative to the conductive brush assembly. The ion generator drives the conductive plate to clean the static electricity residue on the first conductive groove and carries the residue to the lower end of the conductive brush assembly for easy collection later.

[0012] This utility model provides a static electricity elimination device for adding an electrostatic discharge device to a tissue dispenser. The specific implementation method is described in conjunction with the attached... Figure 1 To be continued Figure 4 Please provide a detailed explanation. For example... Figure 1As shown, the device includes a main body 1 and an electrostatic elimination mechanism, which consists of a conductive brush assembly 2 and an ion generator 3. The main body 1 contains an electrostatic elimination chamber 11 and a collection chamber 12. The electrostatic elimination chamber 11 is located above the collection chamber 12, and the conductive brush assembly 2 is installed in the electrostatic elimination chamber 11. The collection chamber 12 is used to collect residues generated during the electrostatic elimination process. A first vent 13 is also provided inside the main body 1, connecting the electrostatic elimination chamber 11 and the collection chamber 12 to allow gas flow. Furthermore, at least one dust discharge port 19 is provided at the bottom of the main body 1. The dust discharge port 19 communicates with the collection chamber 12 and is sealed by a sealing cap 20, which is threadedly connected to the main body 1 for easy disassembly and cleaning.
[0013] like Figure 2 As shown, the conductive brush assembly 2 is horizontally disposed within the main body 1, with its bristles extending outward in a spiral motion and forming a first conductive groove 4 and a first conductive protrusion 5 on its inner side. The first conductive groove 4 is an inwardly recessed inner wall of the conductive brush assembly 2, and the first conductive protrusion 5 is an outwardly protruding inner wall of the conductive brush assembly 2; the two are arranged alternately. This structural design ensures that static charge is mainly concentrated in the first conductive groove 4 during conduction, while static electricity residue is less likely to accumulate at the first conductive protrusion 5, thereby improving the static electricity conduction efficiency of the conductive brush assembly 2. Multiple conductive holes 6 are formed on the bristles of the conductive brush assembly 2. The diameter of these conductive holes 6 is smaller than the diameter of the ion release holes 9, which can effectively guide static charge into the interior of the conductive brush assembly 2 and further transfer it to the ion generator 3.
[0014] like Figure 3 As shown, the ion generator 3 is vertically disposed within the conductive brush assembly 2 and can rotate relative to the conductive brush assembly 2. The outer wall of the ion generator 3 extends outward in a spiral, forming a second conductive protrusion 7 and a second conductive groove 8 on the outer side. The second conductive groove 8 is an inward recess of the outer wall of the ion generator 3, and the second conductive protrusion 7 is an outward protrusion of the outer wall of the ion generator 3; the two are also staggered. The second conductive protrusion 7 cooperates with the first conductive groove 4, and a conductive sheet 10 is fixedly disposed on the second conductive protrusion 7. The conductive sheet 10 is used to abut against the first conductive groove 4, thereby achieving efficient conduction of static charge. Multiple ion release holes 9 are provided on the outer wall of the ion generator 3 for releasing negative ions to neutralize static electricity. At least one second vent hole 23 is also provided at the bottom of the ion generator 3. A one-way valve 24 is disposed in the second vent hole 23. The one-way valve 24 allows airflow to flow unidirectionally from the bottom of the ion generator 3 into the conductive brush assembly 2, ensuring stable airflow direction during the static elimination process.
[0015] like Figure 4As shown, a drive mechanism is also provided inside the main body 1, which includes a rotating shaft 17 and a handle 18. The rotating shaft 17 is vertically installed inside the main body 1 and can rotate around its own axis. The rotating shaft 17 is installed inside the connecting rod 16, and the connecting rod 16 is splined with the rotating shaft 17, so that the connecting rod 16 can rotate synchronously with the rotating shaft 17, and the connecting rod 16 can move up and down relative to the rotating shaft 17. The handle 18 is fixedly connected to the lower end of the rotating shaft 17 and is installed outside the main body 1. The user can drive the rotating shaft 17 to rotate by operating the handle 18, thereby driving the connecting rod 16 and the ion generator 3 to rotate synchronously. The lower end of the connecting rod 16 abuts against the upper end face of the lower pressure plate 14, and the lower pressure plate 14 is slidably installed in the collection chamber 12. In the initial state, the lower pressure plate 14 blocks the first vent hole 13. A spring 15 is installed inside the collection chamber 12. The spring 15 connects the main body 1 and the lower pressure plate 14. When the connecting rod 16 moves downward, the lower pressure plate 14 is pushed downward, thereby opening the first vent 13 and allowing the gas in the electrostatic elimination chamber 11 to flow into the collection chamber 12.
[0016] The main body 1 has an air inlet 21 and an air outlet 22, both of which are connected to the static elimination chamber 11. The air inlet 21 is located above the conductive brush assembly 2. In actual use, external air enters the static elimination chamber 11 through the air inlet 21. After passing through the conductive brush assembly 2 and the ion generator 3, the air carrying negative ions is discharged from the main body 1 through the air outlet 22, thereby neutralizing and eliminating static electricity. After static electricity has been eliminated for a period of time, the user can rotate the ion generator 3 by operating the handle 18. The ion generator 3 rotates and moves up and down relative to the conductive brush assembly 2. The conductive plate 10 on the ion generator 3 cleans the static electricity residue on the first conductive groove 4 and carries the residue to the lower end of the conductive brush assembly 2, where it finally falls into the collection chamber 12. The residue in the collection chamber 12 can be discharged from the dust outlet 19 by opening the sealing cover 20 for easy cleaning later.
[0017] In specific application scenarios, when a tissue dispenser is running, static electricity generated by friction can adhere to the inside of the main body 1 or the tissue paper, affecting the user's operating experience and posing hygiene risks. At this time, activating the static elimination device allows outside air to enter the static elimination chamber 11 through the air inlet 21. After passing through the conductive holes 6 of the conductive brush assembly 2 and the ion release holes 9 of the ion generator 3, static electricity is introduced into the ion generator 3 and neutralized by negative ions before being discharged outside the main body 1. During this process, the design of the first conductive groove 4 and the first conductive protrusion 5 of the conductive brush assembly 2 effectively improves the static electricity conduction efficiency, while the second conductive protrusion 7 and the conductive sheet 10 of the ion generator 3 further enhance the static electricity removal effect. When it is necessary to clean static residue, the user can rotate the ion generator 3 through the operating handle 18. The up-and-down movement of the ion generator 3 drives the conductive sheet 10 to clean the first conductive groove 4, carrying the residue into the collection chamber 12, and finally discharging it through the dust outlet 19. The entire device has a compact structure, is easy to operate, and can effectively solve the problems caused by static electricity in tissue dispensers, improving the user experience and the hygiene performance of the equipment.
[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
