[0026] Example 1

[0027] Example 1 is basically as shown in the appendix. Figures 1-2 As shown, Figure 1 The illustrated air-blasting dental cleaning device includes a body 1, with an air-blasting pipe 2 running through the inside of the body 1. A nozzle 3 is connected to the left end of the air-blasting pipe 2, and an air pump is connected to the right end. A sand tank 4 is fixedly installed on the upper end of the body 1. The sand tank 4 is used to store the salt sand required for air-blasting and can be connected to the air-blasting pipe 2.

[0028] It also includes an adjustment component, which includes a mounting shell 5, an input pipe 6, and an output pipe 7. The mounting shell 5 is fixedly installed on the upper end of the sand tank 4. The input pipe 6 and the output pipe 7 are both located between the mounting shell 5 and the machine body 1. The input pipe 6 is located on the right side of the sand tank 4, and the output pipe 7 is located on the left side of the sand tank 4. One end of the output pipe 7 and the input pipe 6 are connected to the mounting shell 5, and the other end is connected to the sandblasting pipe 2.

[0029] like Figure 2 As shown, a spring 8 is fixedly installed on the inner wall of the upper end of the mounting shell 5. A moving block 9 is fixedly installed on the lower end of the spring 8. An adjusting rod 10 extending into the sand tank 4 is fixedly installed on the lower end of the moving block 9. A material conveying trough 11 is provided between the sand tank 4 and the sandblasting pipe 2, and the material conveying trough 11 passes through the sand tank 4 and the machine body 1. A baffle post 12 is fixedly installed on the lower end of the adjusting rod 10. The baffle post 12 is slidably disposed in the material conveying trough 11 and contacts the inner wall of the material conveying trough 11. The length of the baffle post 12 is greater than the moving distance of the moving block 9. The wall has a through groove 13, and the distance between the through groove 13 and the upper end of the baffle column 12 is set to 2-5cm. The inlet pipe 6 of the through groove 13 is equipped with a regulating valve 14, and the outlet pipe 7 is equipped with a one-way valve 15. Six support blocks 16 are evenly fixedly installed on the outer wall of the regulating rod 10. The support blocks 16 can support the regulating rod 10, thereby extending the service life of the spring 8. At the same time, the spring 8 is always in a compressed state, so that the baffle column 12 and the conveying trough 11 fit more tightly, preventing the salt sand from leaking from the sand tank 4 due to the shaking of the sandblasting and cleaning equipment.

[0030] The specific implementation process is as follows:

[0031] When in use, the staff opens the air pump, and when the compressed gas enters into the sand blasting pipeline 2, part of the compressed gas will enter into the inside of the installation shell 5 through the input pipe 6. With the gradual increase of the air pressure in the installation shell 5, the moving block 9 moves upwards, thereby increasing the inside space of the installation shell 5 and reducing the air pressure in the installation shell 5. When the moving block 9 moves upwards, the adjusting rod 10 will be driven to move upwards, so that the blocking column 12 leaves the feeding groove 11, and the salt sand in the sand tank 4 enters into the feeding groove 11 through the through slot 13 on the outer wall of the blocking column 12, and finally enters into the sand blasting pipeline 2, and is sprayed out from the nozzle 3 along with the airflow in the sand blasting pipeline 2, thereby cleaning the surface of the teeth. When stopping working, the staff closes the air pump, and the air pressure in the installation shell 5 decreases, and the moving block 9 is reset downwards under the action of the spring 8, so that the blocking column 12 blocks the feeding groove 11, thereby preventing the salt sand from leaking and directly contacting with the external environment. In this process, the sand blasting dental cleaning device can perform sand blasting as long as the compressed gas is input, and when stopping working, the salt sand will be closed in the sand tank 4 by the blocking column 12, which can effectively prevent the leakage of the salt sand and prevent the salt sand from being affected by moisture and solidification, thereby affecting the cleaning effect.

[0032] Embodiment 2

[0033] The principle of embodiment 2 is basically the same as that of embodiment 1, and the difference lies in that, as shown in Figure 3 , the rotating disc 17 is rotatably installed on the inner wall of the upper end of the installation shell 5, and the spring 8 is fixedly installed on the lower end of the rotating disc 17. A plurality of rotating blades 18 are uniformly fixedly installed on the outer wall of one end of the adjusting rod 10 in the installation shell 5, as shown in Figure 4 , the mounting block 19 is fixedly installed on the lower end of the adjusting rod 10, and the auger 20 is fixedly installed on the lower end of the mounting block 19. The mounting block 19 and the auger 20 are in abutment with the inner wall of the feeding groove 11.

[0034] By arranging the rotating disc 17 on the inner wall of the upper end of the installation shell 5, the moving block 9 and the adjusting rod 10 can rotate. When the compressed gas enters into the installation shell 5 through the input pipe 6, the compressed gas will blow the rotating blades 18, so that the adjusting rod 10 rotates in the sand tank 4. The rotating adjusting rod 10 drives the support blocks 16 on the outer wall of the adjusting rod 10 to stir in the sand tank 4, so that the salt sand in the sand tank 4 is more uniform, and the salt sand can also prevent the feeding groove 11 from being blocked. At the same time, the auger 20 also rotates with the adjusting rod 10. The faster the rotating speed of the adjusting rod 10 is, the faster the speed of the auger 20 for conveying the salt sand is. The slower the rotating speed of the adjusting rod 10 is, the slower the speed of the auger 20 for conveying the salt sand is, thereby controlling the amount of salt sand by controlling the rotating speed of the adjusting rod 10.

[0035] Embodiment 3

[0036] The principle of the embodiment 3 is substantially same as that of the embodiment 1, except that the upper end of the adjusting rod 10 is slidably penetrated through the mounting shell 5, and the adjusting rod 10 is rotatably and sealingly connected with the mounting shell 5, and the staff can manually pull the adjusting rod 10 upward, so that the sudden situation can be responded more quickly.

[0037] The above is only the embodiment of the present application, and the specific technical solutions and / or common knowledge of the scheme are not described in detail. It should be pointed out that for those skilled in the art, without departing from the technical scheme of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like in the specification can be used to explain the content of the claims.
