Description

Technical Field

[0001] This utility model relates to the field of pit and fissure sealant application technology, specifically to an extrusion coating device for pit and fissure sealant. Background Technology

[0002] Pit and fissure sealant, also known as anti-caries coating, is a new type of dental polymer material developed in the 1960s. It is applied to the pits and fissures on the tooth surface, and after curing, it forms a barrier that effectively seals the pits and fissures, isolating tooth-causing factors in the oral environment and preventing tooth decay. This has opened up new avenues for caries prevention in oral medicine. Pit and fissure sealant is one of the important methods for preventing caries. When used in combination with fluoride caries prevention, it can eliminate the vast majority of caries in the population. Extrusion coating devices can apply the sealant, but existing extrusion coating devices are mostly unidirectional extrusion structures, squeezing out only the internal sealant. Multiple tools are needed to evenly apply the sealant, and feeding is inconvenient, making it rather cumbersome to use. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-4 This utility model provides a technical solution: an extrusion coating device for pit and fissure sealant, comprising a main body 10, a friction block 20, a slide rod 30, a connecting block 301, a rubber block 302, a connecting rope 40, a blocking block 401, a feed inlet 402, an outlet pipe 50, a guide pipe 501, a connecting rod 60, and a brush 601;

[0032] The extrusion coating device for this pit and fissure sealant facilitates its application. The specific implementation method is as follows:

[0033] The main body 10 is a hollow cylindrical shell, and friction blocks 20 are continuously arranged on the surface of the main body 10. A slide rod 30 is embedded in one side of the surface of the main body 10, and a rubber block 302 is connected to one side of the slide rod 30 inside the main body 10. A connecting block 301 is connected to one side of the slide rod 30, and the connecting block 301 is located on the outside of the main body 10. A feed inlet 402 is embedded in the surface of the main body 10, and a blocking block 401 is embedded inside the feed inlet 402. A connecting rope 40 is connected to the surface of the blocking block 401, and the other end of the connecting rope 40 is connected to the main body 10. An outlet pipe 50 is installed on one side of the surface of the main body 10, and a guide pipe 501 is sleeved on the surface of the outlet pipe 50. A connecting rod 60 is connected to one side of the surface of the main body 10, and the bottom of the connecting rod 60... The body is equipped with a brush 601. The bottom surface of the main body 10 is rounded, and the main body 10 and the slide rod 30 are slidably connected. The bottom of the main body 10 is provided with a hole, and the hole of the main body 10 is connected to the outlet pipe 50. The bottom of the friction block 20 is set with an arc-shaped structure, and the friction block 20 is in contact with the inner wall of the main body 10. The main body 10 and the friction block 20 are slidably connected. The block 401 is embedded in the inlet 402 and is located on the surface of the main body 10 near the slide rod 30. The outlet pipe 50 and the guide pipe 501 are slidably connected, and the guide pipe 501 is sleeved and installed at the bottom of the outlet pipe 50. The connecting rod 60 is located on the outside of the guide pipe 501, and the brush 601 is located on the bottom side of the guide pipe 501.

[0034] like Figure 1Pull the plug 401 outward to remove it from the inlet 402. The blockage is removed, allowing the inlet 402 to be opened. Simultaneously, the rubber block 302 pulls the plug 401 to prevent it from being lost. The pit sealant can then be poured into the main body 10 through the inlet 402 for easy replenishment and application. After sealing, install the plug 401 inside the inlet 402 to block it. Simultaneously, push the connecting block 301 downward, causing the sliding rod 30 to move downward within the main body 10. This pushes the rubber block 302 downward, allowing it to move within the main body 10. The body 10 moves downwards, causing the rubber block 302 to push the fissure sealant to the bottom of the body 10.
