Technical Field
[0001] This utility model relates to the field of tongue coating removal technology, specifically to an oral tongue coating removal device. Background Technology
[0002] Tongue coating refers to a thin film that forms on the surface of the tongue. It is usually composed of food debris, bacteria, dead cells, and other substances. The color and thickness of the tongue coating can reflect a person's oral health and overall health. Tongue cleaning is part of oral hygiene, which mainly removes bacteria, food debris, and dead cells accumulated on the surface of the tongue. Good tongue cleaning helps maintain fresh breath, prevent oral diseases, and promote overall health.
[0003] Traditional tongue cleaning devices use hard scrapers, which are inefficient and leave little to no residue. Food debris and bacteria can accumulate in the mouth, leading to serious oral diseases and posing a significant health risk. Furthermore, these devices require regular disassembly and replacement of the scraper and other cleaning components. Disassembly and reassembly of the scraper in conventional devices are cumbersome and time-consuming. To address these issues, a novel oral tongue cleaning device is proposed. Utility Model Content

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0020] Reference Figure 1-4 As shown, an oral cavity and tongue coating cleaning device includes a handle 1. A control plate 2 is fixedly installed at the center of the front side of the handle 1 to facilitate the control of the rotation speed of the motor 8 and the brightness of the light 18. A battery cover 3 is threadedly connected to the upper side of the handle 1. Several handle grooves 4 are opened on the surface of the battery cover 3. A partition plate 5 is fixedly connected to the upper end of the inside of the handle 1. The inside of the handle 1 and the top of the partition plate 5 form a battery groove 6.
[0021] Specifically, a mounting plate 7 is fixedly connected to the middle of the handle 1. A motor 8 is fixedly installed at the upper center of the mounting plate 7. The output end of the motor 8 passes through the upper side of the mounting plate 7 and is fixedly connected to a fixing plate 9. A connecting rod 10 is fixedly connected to the lower right end of the fixing plate 9. A spherical sliding block 11 is fixedly connected to the lower side of the connecting rod 10. A sliding plate 12 is slidably connected to the lower end of the handle 1. A sloping groove 13 is provided at the upper center of the sliding plate 12. The height of the right end of the sloping groove 13 is higher than that of the left end. The lower side of the spherical sliding block 11 is slidably connected to the interior of the sloping groove 13. A lifting rod 14 is fixedly connected to the lower center of the sliding plate 12. A spring 15 is sleeved on the surface of the lifting rod 14. The upper end of the spring 15 is fixedly connected to the lower side of the sliding plate 12. The lower end of the spring 15 is fixedly connected to the upper side of the bottom plate of the handle 1, ensuring that the spherical sliding block 11 abuts against the bottom of the sloping groove 13.
[0022] Specifically, the lower side of the lifting rod 14 passes through the bottom plate of the handle 1 and is fixedly connected to the connecting sleeve 16. The lower end of the connecting sleeve 16 is threaded with a soft brush 17, which can effectively clean the tongue coating. The front and rear ends of the lower side of the handle 1 are fixedly connected with lights 18, which makes it easy to observe the cleaning status of the tongue coating in the oral cavity. The left and right ends of the lower side of the handle 1 are fixedly connected with mounting rods 19. The lower sides of the two mounting rods 19 are fixedly connected with limit plates 20. The lower sides of the two limit plates 20 are fixedly connected with threaded rods 21. The surfaces of the two threaded rods 21 are slidably connected with hard scrapers 22 for secondary cleaning of the tongue coating. The lower side of the threaded rods 21 is threaded with a fixing cap 23, which makes it easy to remove and install the hard scrapers 22.
[0023] Working principle: When the hard scraper 22 needs to be replaced, rotate the fixing cap 23 to remove it, take off the hard scraper 22, install the replacement hard scraper 22 on the threaded rod 21, and rotate the fixing cap 23 to fix the hard scraper 22. When cleaning the tongue coating, the rotation speed of the motor 8 and the brightness of the light 18 are controlled by the control board 2. Under the elastic force of the spring 15, the spherical sliding block 11 abuts against the inside of the inclined groove 13. As the motor 8 and the fixing plate 9 rotate, the spherical sliding block 11 rotates inside the inclined groove 13. The height of the right end of the inclined groove 13 is higher than that of the left end. The slide plate 12 and the lifting rod 14 will move up and down in a straight line as the spherical sliding block 11 rotates. Correspondingly, the soft brush 17 cleans the tongue coating once in the reciprocating motion. The control handle 1 moves the hard scraper 22 from the depth of the oral cavity to the outside for a second cleaning of the tongue coating, effectively improving the cleaning efficiency of the tongue coating.
