Description

Technical Field

[0001] This utility model relates to the field of ultrasonic sandblasting handle technology, and in particular to a detachable dual-function ultrasonic sandblasting handle. Background Technology

[0002] Air polishing equipment uses compressed gas to propel dental polishing powder onto the tooth surface, where it mixes with a liquid medium to clean the teeth. Ultrasonic scaling equipment uses ultrasonic waves to propel a vibrating scaling tip deep into the mouth, loosening plaque and tartar, breaking down surface debris, while continuous rinsing with water removes tartar. The effective combination of ultrasonic and air polishing can effectively remove plaque, soft deposits, early tartar, tobacco stains, and tea stains from both above and below the gum line, effectively preventing periodontal disease and maintaining dental health.

[0003] A flexible hose is connected between the sandblasting handle and the equipment to ensure that the sandblasting can be smoothly ejected from the handle. However, the handle and the hose are usually fixedly connected, which makes it inconvenient to disassemble when the hose is damaged or needs to be cleaned. Based on this, this application proposes a detachable dual-function sandblasting ultrasonic handle to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a detachable dual-function ultrasonic sandblasting handle.

[0005] The purpose of this utility model is achieved through the following technical solution: a detachable dual-function ultrasonic sandblasting handpiece, including a handpiece and an air tube, a connecting tube installed below the handpiece, one end of the air tube being sleeved with the connecting tube, four threaded posts installed below the handpiece, arranged in a circumferential array around the connecting tube, a cover plate installed at one end of the air tube, all four threaded posts penetrating the cover plate, and a sealing ring installed on the cover plate.

[0006] Optionally, multiple oblique sealing plates are installed on the outside of the connecting pipe.

[0007] Optionally, all four threaded posts are externally threaded with locking caps.

[0008] Optionally, the outer surface of the cover plate is provided with a groove, and the sealing ring is installed in the groove.

[0009] Optionally, the cover plate has four through holes on its exterior, the positions of which correspond to the positions of the four threaded posts.

[0010] This utility model has the following advantages:

[0011] This detachable dual-function ultrasonic sandblasting handpiece has a connecting tube installed at the bottom of the handpiece, allowing the air tube to be fitted onto the connecting tube. Threaded posts are installed around the connecting tube, and a cover plate is installed at one end of the air tube. All four threaded posts penetrate the cover plate, and locking caps are installed on the external threads of the threaded posts, ensuring a tight connection between the air tube and the handpiece. This facilitates disassembly and assembly. Furthermore, to improve the seal between the two, a sealing ring is installed on the cover plate. The sealing ring can be deformed under pressure to ensure a good seal between the two components. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0017] like Figures 1 to 3 As shown, a detachable dual-function ultrasonic sandblasting handpiece includes a handpiece 1 and an air tube 2. A connecting tube 4 is installed below the handpiece 1. One end of the air tube 2 is fitted with the connecting tube 4. Four threaded posts 6 are installed below the handpiece 1, arranged in a circumferential array around the connecting tube 4. A cover plate 7 is installed at one end of the air tube 2. All four threaded posts 6 penetrate the cover plate 7. A sealing ring is installed on the cover plate 7.

[0018] As an optional technical solution of this utility model, multiple inclined sealing plates 5 are installed on the outside of the connecting pipe 4, which can improve the sealing effect between the connecting pipe 4 and the air pipe 2, so that the two can achieve an interference fit.

[0019] As an optional technical solution of this utility model, the four threaded posts 6 are all threaded with locking caps 3, which makes it easy to tightly fit the cover plate 7 and the handle 1 by tightening the locking caps 3.

[0020] As an optional technical solution of this utility model, a groove 8 is provided on the outer surface of the cover plate 7, and the sealing ring is installed in the groove 8. This facilitates the installation of the sealing ring, and the size between the two is compatible to prevent the sealing ring from falling off.

[0021] As an optional technical solution of this utility model, the cover plate 7 has four through holes on its exterior, the positions of which correspond to the positions of the four threaded posts 6, which facilitates the assembly and disassembly of the cover plate 7.

[0022] In summary, the features, assembly method, usage process, and functions of each component in this utility model are as follows: A connecting tube 4 is installed below the handle 1, allowing the air tube 2 to be fitted onto the connecting tube 4. Threaded posts 6 are installed around the connecting tube 4, and a cover plate 7 is installed at one end of the air tube 2. All four threaded posts 6 penetrate the cover plate 7, and a locking cap 3 is installed on the external threads of the threaded posts 6, ensuring a tight connection between the air tube 2 and the handle 1, facilitating disassembly and assembly. Furthermore, to improve the sealing between the two, a sealing ring is installed on the cover plate 7. The sealing ring can be deformed under pressure to ensure a good seal between the two components.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
