Description

Technical Field

[0001] This invention relates to the field of cleaning device technology, and more particularly to an oral examination device for dental use. Background Technology

[0002] The oral cavity is a very important structure in the human body. Regular oral examinations have different meanings for different people. For example, in childhood, the main issues are tooth decay and malocclusion, and parents should take their children for a check-up every six months. In adulthood, the main issues are tooth decay and periodontal disease. In dental examinations, the most common focus is on monitoring the teeth. This process requires the use of some devices to complete the work, such as using a mouth mirror to reflect the teeth that are difficult to observe.

[0003] However, existing examination devices often have the following problems in actual operation: First, in addition to reflecting light to the teeth, existing mouth mirrors are also used to open up the soft tissue in the mouth for easy observation. Since a lot of saliva is produced in the mouth when the mouth needs to be opened for examination, the mouth mirror will inevitably be contaminated with a lot of saliva and other mucus when used in the mouth, which will seriously affect the smoothness of the mirror surface and thus affect the observation effect of medical staff. It is necessary to use cleaning tools such as alcohol swabs to clean and wipe the mouth mirror.

[0004] Secondly, the cleaning effectiveness of cleaning tools such as alcohol swabs decreases rapidly with repeated use. In order to ensure the cleaning effect of the mouth mirror, it is necessary to constantly prepare cleaning tools such as alcohol swabs, which is cumbersome and time-consuming, and cannot achieve quick and effective cleaning, thus affecting subsequent use. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by providing a dental examination device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] In the above-mentioned dental examination device, the bottom of the rack is engaged with a transmission tooth, which is rotatably connected to the inside of the connecting cylinder. The bottom of the transmission tooth is engaged with a tooth groove, which is located on the top of the cleaning box.

[0012] In the above-mentioned dental examination device, four springs are fixedly connected inside the fixed ring, and a locking block is fixedly connected to the other end of the spring. The four springs are distributed in a circular pattern inside the fixed ring, and the locking block is engaged with the fixed sleeve.

[0013] In the above-mentioned dental examination device, a plug is fixedly connected to the surface of the rack, and a slot is provided at the bottom of one of the support rods, and the plug is inserted into the slot.

[0014] In the above-mentioned dental examination device, a connecting block is fixedly connected to the top of the cleaning box, and the cleaning box is slidably connected to the bottom of the connecting cylinder through the connecting block.

[0015] In the above-mentioned dental examination device, the surface of the top support is symmetrically fixedly connected with a fixing head, and the inside of the cleaning box is symmetrically fixedly connected with two elastic blocks, which are engaged with the fixing head.

[0016] In the above-mentioned dental examination device, three retaining ring blocks are fixedly connected inside the fixed sleeve, and the three retaining ring blocks are distributed in a circumferential manner inside the fixed sleeve.

[0017] Compared with existing technologies, the advantages of this dental examination device are:

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] Reference Figures 1-9A dental examination device includes a connecting cylinder 1, a fixing sleeve 2 slidably connected inside the connecting cylinder 1, two support rods 3 fixedly connected to one side of the surface of the fixing sleeve 2, a positioning sleeve 4 fixedly connected to the other end of the support rods 3, a fixing ring 5 rotatably connected inside the connecting cylinder 1, the fixing ring 5 slidably engaging with the fixing sleeve 2, a mouth mirror 6 engaging inside the fixing sleeve 2, the mouth mirror 6 slidably connected to the positioning sleeve 4, a connecting groove 7 is formed inside the connecting cylinder 1, one of the support rods 3 is slidably connected to the connecting groove 7, a rotating wheel 8 is rotatably connected inside the connecting groove 7, a toothed tooth 9 is fixedly connected to one side of the surface of the rotating wheel 8, a rack 10 is engaged at the bottom of the toothed tooth 9, the rack 10 is slidably connected to the connecting groove 7, the surface of the rack 10 is inserted into the support rod 3, and a cleaning box is fixedly connected to the bottom of the connecting cylinder 1. 11. A top support 12 is inserted into one side of the surface of the cleaning box 11. A contraction spring 13 is fixedly connected inside the top support 12. A push plate 14 is fixedly connected to the surface of the contraction spring 13. A cleaning cotton 15 is fixedly connected to the surface of the push plate 14. The cleaning cotton 15 is inserted into the interior of the cleaning box 11. A storage groove 16 is opened on the surface of the cleaning box 11. Two sliding slots 17 are opened inside the storage groove 16, and the two sliding slots 17 are symmetrically opened on both sides of the cleaning cotton 15. A connecting spring 18 is fixedly connected inside the sliding slot 17. A cutting plate 19 is fixedly connected to the other end of the connecting spring 18. The cutting plate 19 slides through the storage groove 16 and is slidably connected to the interior of the cleaning box 11. A linkage block 20 is fixedly connected to the surface of the cutting plate 19 and is slidably connected to the interior of the storage groove 16.

[0034] The rotating wheel 8 drives the toothed gear 9 to rotate, which in turn drives the rack 10 to slide through the meshing effect. This causes the fixing sleeve 2 to enter the fixing ring 5 and be fixed. During the sliding of the rack 10, the cleaning box 11 will slide and extend from the bottom of the connecting cylinder 1 to adapt to the length of the mouth mirror 6. Then, by rotating the fixing ring 5, the mouth mirror 6 is forced to rotate as well. The mouth mirror 6 will eventually enter the interior of the cleaning box 11 through the storage slot 16 and push the cutting plate 19 to slide. This forces the contraction spring 13 to push the cleaning cotton 15 to slide out and, after contacting the mirror surface, clean and wipe the mirror surface in conjunction with the rotation of the mouth mirror 6. After cleaning, the mouth mirror 6 rotates out of the cleaning box 11. The cutting plate 19 slides again due to the elastic recovery effect of the connecting spring 18, and cuts the used cleaning cotton 15 during the sliding process. This facilitates wiping and cleaning and ensures the overall cleaning effect.

[0035] The bottom of the rack 10 is engaged with a transmission tooth 21, which is rotatably connected to the inside of the connecting cylinder 1. The bottom of the transmission tooth 21 is engaged with a tooth groove 22, which is located at the top of the cleaning box 11. A connecting block 27 is fixedly connected to the top of the cleaning box 11. The cleaning box 11 is slidably connected to the bottom of the connecting cylinder 1 via the connecting block 27. Through the rotation of the transmission tooth 21, the meshing effect between the transmission tooth 21 and the tooth groove 22 during the sliding of the rack 10 forces the cleaning box 11 to slide towards the side closer to the mirror surface via the sliding effect of the connecting block 27. This adapts to the working length of the mouth mirror 6 and ensures that the mirror surface can smoothly enter the interior of the cleaning box 11.

[0036] Four springs 23 are fixedly connected inside the fixed ring 5. The other end of each spring 23 is fixedly connected to a locking block 24. The four springs 23 are arranged in a circular pattern inside the fixed ring 5. The locking block 24 engages with the fixed sleeve 2. Three retaining spring blocks 30 are fixedly connected inside the fixed sleeve 2. The three retaining spring blocks 30 are arranged in a circular pattern inside the fixed sleeve 2. The retaining spring blocks 30 can clamp and fix the handle of the mouth mirror 6, fixing it inside the fixed sleeve 2. After the fixed sleeve 2 slides into the fixed ring 5, the springs 23 push the locking block 24 to clamp and fix the fixed sleeve 2, ensuring that the mouth mirror 6 can rotate smoothly when the fixed ring 5 rotates.

[0037] A plug 25 is fixedly connected to the surface of the rack 10. A slot 26 is provided at the bottom of one of the support rods 3. The plug 25 is inserted into the slot 26. Through the insertion effect between the plug 25 and the slot 26, the support rod 3 can be smoothly driven to slide during the sliding process of the rack 10. When the support rod 3 rotates, the rack 10 will not hinder the rotation effect.

[0038] The surface of the top support 12 is symmetrically fixed with a fixing head 28, and the inside of the cleaning box 11 is symmetrically fixed with two elastic blocks 29. The elastic blocks 29 are engaged with the fixing heads 28. The top support 12 is inserted into one side of the cleaning box 11 through the fixing head 28. The fixing effect of the elastic blocks 29 on the fixing head 28 can ensure the fixation effect of the top support 12.

[0039] The working principle and usage of this invention are explained in detail below: In use, firstly, the handle of the mouth mirror 6 can be clamped and fixed by the three snap ring blocks 30, so that it is fixed inside the fixing sleeve 2. Through the rotation effect of the rotating wheel 8, the rack 10 can be driven to slide through the meshing effect, and the fixing sleeve 2 can be driven into the fixing ring 5 and fixed. Through the rotation action of the transmission tooth 21, during the sliding of the rack 10, the meshing effect of the transmission tooth 21 and the tooth groove 22 forces the cleaning box 11 to slide towards the side closer to the mirror surface through the sliding effect of the connecting block 27, so as to adapt to the working length of the mouth mirror 6 and ensure that the mirror surface can smoothly enter the cleaning box 11.

[0040] The second step involves rotating the fixing ring 5, which forces the mouth mirror 6 to rotate as well. The mouth mirror 6 eventually enters the cleaning box 11 through the storage slot 16 and pushes the cutting plate 19 to slide, forcing the contraction spring 13 to push the cleaning cotton 15 to slide out. After contacting the mirror surface, the cutting plate 19 rotates out of the cleaning box 11 in conjunction with the rotation of the mouth mirror 6. After cleaning, the mouth mirror 6 rotates out of the cleaning box 11, and the cutting plate 19 slides again due to the elastic recovery effect of the connecting spring 18, cutting the used cleaning cotton 15 during the sliding process.

[0041] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
