[0040] Based on this, the utility model provides a medical sandblasting device, which adopts multiple powder tanks 2, can increase the storage capacity of sand powder, and can be used to store different types of sand powder. During the teeth cleaning process, there is no need to frequently replace the powder tanks 2, which helps to improve the teeth cleaning efficiency.

[0041] Embodiment 1

[0042] like Figures 1 to 4 As shown, the embodiment of the present application provides a medical sandblasting device, including a sandblasting machine body 1, a plurality of powder tanks 2, a plurality of first transport components 3 and a second transport component 4. The plurality of powder tanks 2 can be detachably mounted on the sandblasting machine body 1. The plurality of first transport components 3 are respectively connected to the plurality of powder tanks 2 and are located in the sandblasting machine body 1. The second transport component 4 is connected to the plurality of first transport components 3 and is configured to be able to collect sand powder in the plurality of first transport components 3 under the action of an external air compressor.

[0043] It should be noted that in this embodiment, the number of powder tanks 2 and the number of first transport components 3 are both set to three for illustration. Of course, in other embodiments, the number of powder tanks 2 and the number of first transport components 3 can also be set to two, four, five, etc., according to actual application requirements, which are not limited here.

[0044] Specifically, when the device is used, the sand powder in the powder tank 2 is lifted up by the external air compressor and enters the first transport component 3. It should be noted that the working principle of the powder tank 2 can be found in the Chinese utility model patent (patent application number 202222689280.4). The sand powder enters the second transport component 4 through the first transport component 3, and under the action of the external air compressor, the sand powder is output from the second transport component 4 and mixed with the water in the external waterway and sprayed out together.

[0045] The medical sandblasting device provided in the present application stores the same or different types of sand powder in multiple powder tanks 2 according to actual application requirements. During the teeth cleaning process, when only the same type of sand powder is needed for sandblasting, after the sand powder in one of the powder tanks 2 is exhausted, the sand powder in the remaining powder tanks 2 can be used to continue sandblasting. During the teeth cleaning process, if different types of sand powder need to be replaced for sandblasting, or different types of sand powder need to be mixed for sandblasting, medical staff select the corresponding powder tank 2 for sandblasting according to actual application requirements. For example, powder with a hardness slightly lower than that of tooth enamel is used for polishing and removing pigments, powder with a hardness between enamel and essence is used for removing carious enamel, and powder with a hardness less than that of dentin is used for removing carious dentin, so as to realize precise medical treatment of the oral cavity. In summary, during the teeth cleaning process, avoiding medical staff from frequently changing powder tanks 2 can reduce teeth cleaning time, help improve teeth cleaning efficiency, and also help improve convenience of use.

[0046] Optionally, the medical sandblasting device further comprises a water tank 6 , which is mounted on the sandblasting machine body 1 .

[0047] It should be noted that in this embodiment, the water tank 6 is set to be a truncated cone shape for illustration. Of course, in other embodiments, the water tank 6 can also be set to other shapes such as a cylinder according to actual application requirements, which is not limited here.

[0048] In one embodiment of the present application, see Figures 1 to 4 The first transport component 3 includes a first transport pipe 31 and an electromagnetic switch valve 32. The first transport pipe 31 is connected between the powder tank 2 and the second transport component 4. The electromagnetic switch valve 32 is installed on the first transport pipe 31 and is used to control the opening and closing of the first transport pipe 31.

[0049] Specifically, when the three powder tanks 2 contain the same type of sand powder, during the teeth cleaning process, one of the electromagnetic switch valves 32 is in an open state, and the other two electromagnetic switch valves 32 are in a closed state. Therefore, the sand powder in the corresponding powder tank 2 enters the second transport component 4 through the first transport pipe 31, until the sand powder in the powder tank 2 is consumed, and the electromagnetic switch valve 32 switches to a closed state. At the same time, another electromagnetic switch valve 32 switches from a closed state to an open state, and the corresponding powder tank 2 enters the second transport component 4 through the first transport pipe 31.

[0050] When the three powder tanks 2 contain different types of sand powder, in this embodiment, the three types of sand powder are respectively named as the first sand powder, the second sand powder and the third sand powder. Similarly, the three powder tanks 2 are respectively named as the first powder tank 2, the second powder tank 2 and the third powder tank 2, and the three electromagnetic switch valves 32 are respectively named as the first electromagnetic switch valve 32, the second electromagnetic switch valve 32 and the third electromagnetic switch valve 32.

[0051] When only the first sand powder is needed, the first electromagnetic switch valve 32 is in an open state, and the first sand powder enters the second transport assembly 4 through the first electromagnetic switch valve 32 and the corresponding first transport pipe 31. At the same time, the second electromagnetic switch valve 32 and the third electromagnetic switch valve 32 are both in a closed state.

[0052] When only the second sand powder is needed, the second electromagnetic switch valve 32 is in an open state, and the second sand powder enters the second transport assembly 4 through the second electromagnetic switch valve 32 and the corresponding first transport pipe 31. At the same time, the first electromagnetic switch valve 32 and the third electromagnetic switch valve 32 are both in a closed state.

[0053] When only the third sand powder is needed, the third electromagnetic switch valve 32 is in an open state, and the third sand powder enters the second transport assembly 4 through the third electromagnetic switch valve 32 and the corresponding first transport pipe 31. At the same time, the first electromagnetic switch valve 32 and the second electromagnetic switch valve 32 are both in a closed state.

[0054] When the first sand powder and the second sand powder need to be mixed for use, the first electromagnetic switch valve 32 and the second electromagnetic switch valve 32 are in an open state, and the third electromagnetic switch valve 32 is in a closed state.

[0055] When the first sand powder and the third sand powder need to be mixed for use, the first electromagnetic switch valve 32 and the third electromagnetic switch valve 32 are in an open state, and the second electromagnetic switch valve 32 is in a closed state.

[0056] When the second sand powder and the third sand powder need to be mixed for use, the second electromagnetic switch valve 32 and the third electromagnetic switch valve 32 are in an open state, and the first electromagnetic switch valve 32 is in a closed state.

[0057] When the first sand powder, the second sand powder and the third sand powder need to be mixed for use, the first electromagnetic switch valve 32 , the second electromagnetic switch valve 32 and the third electromagnetic switch valve 32 are all in an open state.

[0058] In this way, the electromagnetic switch valve 32 is used, and the on-off of the first transport pipe 31 can be controlled by controlling the on-off of the electromagnetic switch valve 32. In actual application, it is convenient for medical personnel to accurately select corresponding sand powder, and the control is convenient, which helps to improve the convenience of use.

[0059] In one embodiment of the present application, please refer to Figures 1 to 4 The second transport assembly 4 includes a first transport seat 41, a second transport seat 42, a second transport pipe 43 and a third transport pipe 44. The first transport seat 41 is connected to one end of multiple first transport pipes 31 away from the electromagnetic switch valve 32, the second transport seat 42 is connected to the first transport seat 41, the second transport pipe 43 is installed between the second transport seat 42 and the external air compressor, and the third transport pipe 44 is installed on the second transport seat 42 and is used to output sand powder.

[0060] Specifically, when different types of sand powder need to be mixed for use, the different types of sand powder enter the first transport seat 41 through the corresponding first transport pipe 31, and enter the second transport seat 42 after being mixed in the first transport seat 41. The second transport pipe 43 is located between the second transport seat 42 and the external air compressor. Under the action of the external air compressor, the mixed sand powder is output from the third transport pipe 44. It should be noted that the end of the third transport pipe 44 away from the second transport seat 42 is connected to the external water pipe. Therefore, the mixed sand powder can be mixed with water again after passing through the third transport pipe 44, and finally output from the external gun head.

[0061] In this way, the first transport seat 41 can be connected to multiple first transport pipes 31 at the same time, so that the sand powder in the multiple first transport pipes 31 can enter the second transport seat 42. In addition, different types of sand powder can be mixed to ensure that the sandblasting is carried out normally. The second transport seat 42 can be used to transport the mixed sand powder. With the cooperation of the external air compressor, the sand powder can be output to the third transport pipe 44.

[0062] In one embodiment of the present application, see Figures 1 to 4 The first transport seat 41 includes a first seat body 411 and a collecting chamber 412. The first seat body 411 is installed at one end of the multiple first transport pipes 31 away from the electromagnetic switch valve 32. The collecting chamber 412 is opened in the first seat body 411 and is connected to the multiple first transport pipes 31.

[0063] With such arrangement, the collecting chamber 412 can be connected to multiple first transport pipes 31 at the same time, so as to facilitate the collection of sand powder and ensure that the sand powder can be normally transported to the second transport seat 42.

[0064] In one embodiment of the present application, see Figures 1 to 4 The second transport seat 42 includes a second seat body 421, an input passage 422, an air intake passage 423 and an output passage 424. The second seat body 421 can be detachably installed on the first seat body 411. The input passage 422 is opened in the second seat body 421 and is connected to the collecting chamber 412. The air intake passage 423 is opened in the second seat body 421 and is connected to the second transport pipe 43. The output passage 424 is opened in the second seat body 421 and is connected to the third transport pipe 44.

[0065] With such arrangement, the sand powder can enter the second seat body 421 from the collecting chamber 412 through the input passage 422. The compressed gas can enter the second seat body 421 through the air inlet passage 423. Through the output passage 424, under the action of the compressed gas, the sand powder can enter the second seat body 421 from the input passage 422 and then be output from the output passage 424.

[0066] In one embodiment of the present application, please refer to Figures 1 to 4 The second transport component 4 also includes a one-way valve 45, which is installed on the second transport pipe 43.

[0067] With such arrangement, the one-way valve 45 is used, and the compressed gas can only flow from the air compressor to the second seat body 421, which can prevent the compressed gas from driving the sand powder back to the external air compressor, and can effectively protect the external air compressor.

[0068] In one embodiment of the present application, see Figures 1 to 4The first transport seat 41 further includes a guide surface 413 , which is opened at one end of the collecting cavity 412 close to the second transport seat 42 .

[0069] With such arrangement, the guide surface 413 is used, and after the sand powder enters the collecting chamber 412, it is convenient for the sand powder to enter the input passage 422 from the collecting chamber 412, so that the sand powder is easily transported, and the blockage of the collecting chamber 412 can be avoided as much as possible, which helps to improve the convenience of use.

[0070] In one embodiment of the present application, see Figures 1 to 5 The powder tank 2 includes a tank body 21, a cover body 22 and a plurality of stirring members 23. The tank body 21 is detachably mounted on the sandblasting machine body 1. The cover body 22 is detachably mounted on the tank body 21. The stirring members 23 are mounted on the tank body 21 and are configured to stir the sand powder in the tank body 21.

[0071] Specifically, in actual application, since different types of sand powder have different physical properties, the sand powder is easily agglomerated and blocked when stored in the tank body 21 for a long time, resulting in the sand powder being unable to enter the first transport pipe 31 from the tank body 21.

[0072] In this way, the stirring member 23 can be used to stir the sand powder in the tank body 21 to prevent the sand powder from agglomerating in the tank body 21, which is convenient for sandblasting and helps to improve the convenience of use. The cover body 22 and the tank body 21 are designed to be detachably connected, which is convenient for cleaning the tank body 21 and the cover body 22, and for adding sand powder, which helps to further improve the convenience of use.

[0073] In one embodiment of the present application, please refer to Figures 1 to 5 , the stirring member 23 is configured as an air inlet pipe.

[0074] With such arrangement, the external air compressor injects gas into the tank body 21 through the air inlet pipe, and generates vortex to stir the sand powder in the tank body 21 , thereby achieving a good stirring effect and preventing the sand powder in the tank body 21 from agglomerating.

[0075] Embodiment 2

[0076] This embodiment is basically the same as the first embodiment, and the difference is only that: Figures 1 to 7 As shown, the medical sandblasting device also includes a sandblasting gun head 5, which is installed at one end of the multiple first transport pipes 31 away from the sandblasting machine body 1. The second transport component 4 includes multiple second transport seats 42 and multiple second transport pipes 43, the multiple second transport seats 42 are respectively installed on the multiple first transport pipes 31, and the multiple second transport pipes 43 are respectively installed on the multiple second transport seats 42, and are all connected to the external air compressor. The second transport component 4 also includes multiple one-way valves 45, and the multiple one-way valves 45 are respectively installed on the multiple second transport pipes 43.

[0077] Specifically, when the three powder tanks 2 contain different types of sand powder, when the medical staff replaces the corresponding sand powder according to the specific conditions of the patient, they need to first spray out the other types of sand powder in the third transport tube 44, and then they can spray out the relative sand powder. For example, when the third sand powder is needed, the first sand powder and / or the second sand powder in the third transport tube 44 need to be sprayed out first, and then the second sand powder can be used. More specifically, when sandblasting above and below the gums, the sand powder materials used in the two positions are completely different, and mixed use will cause damage to the subgingival soft tissue. Therefore, when the first sand powder and / or the second sand powder are sprayed out, due to the distance between the third transport tube 44 and the sandblasting gun head 5, it is easy to cause a large amount of waste of sand powder in the third transport tube 44, and the treatment cost is high.

[0078] It should be noted that in this embodiment, the number of the second transport base 42, the number of the second transport pipe 43 and the number of the one-way valve 45 are all set to three. Of course, in other embodiments, according to actual application requirements, the second transport base 42, the second transport pipe 43 and the one-way valve 45 can also be set to two, four, five... other numbers, which are not limited here.

[0079] In this way, the plurality of second transport seats 42 and the plurality of first transport pipes 41 are arranged one by one, and the plurality of first transport pipes 41 are joined at the sandblasting gun head 5. Compared with the first embodiment where the first embodiment is joined in the sandblasting machine body 1, different types of sand powder can be separately transported to the sandblasting gun head 5. When different types of sand powder are replaced, the amount of sand powder sprayed can be greatly reduced, avoiding a large amount of sand powder waste, which helps to reduce the cost of treatment.

[0080] One or more embodiments of the present application are intended to cover all such substitutions, modifications and variations that fall within the broad scope of the present application. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of the present application should be included in the protection scope of the present application.
