For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Below is the attached figure Figures 1 to 4 The technical solution of the utility model is further illustrated by specific implementation methods.

[0027] like Figure 1-4 As shown, a sterilizable assembled three-in-one gun for stomatology includes a three-in-one gun body 1 and a connecting assembly 3 for connecting the three-in-one gun body 1 with a dental treatment instrument, one end of the connecting assembly 3 is installed on the pipeline of the dental treatment instrument;

[0028] The three-in-one gun body 1 has a first end and a second end that are oppositely disposed, the first end of the three-in-one gun body 1 is detachably mounted with a nozzle 2, and the other end of the connecting assembly 3 is detachably mounted on the second end of the three-in-one gun body 1;

[0029] The connection assembly 3 includes a docking shell 31, a connection ring 32 and a limit ring 33;

[0030] The limiting ring 33 is fixedly sleeved on the outer side wall of the docking shell 31, and the connecting ring 32 is slidably sleeved on the outer side of the docking shell 31. The limiting ring 33 is used to prevent the connecting ring 32 from detaching from the docking shell 31. The inner side wall of the connecting ring 32 is provided with an internal thread, and the outer side wall of the second end of the three-purpose gun body 1 is provided with an external thread matching the internal thread.

[0031] In this solution, the connection ring 32 is threadedly connected to the second end of the three-in-one gun body 1, which can facilitate the disassembly and assembly between the connection component 3 and the three-in-one gun body 1, thereby facilitating the removal of the three-in-one gun body 1 from the dental treatment instrument for disinfection and preventing cross infection.

[0032] It is worth mentioning that the three-way gun body 1 can be detachably mounted on one end of the connecting component 3 by means of cooperation between external threads and internal threads, and the other end of the connecting component 3 is fixedly mounted on the pipeline of the dental treatment instrument. At this time, the three-way gun body 1 is connected with the pipeline of the dental treatment instrument, and the pipeline is used to provide water and air to the three-way gun body 1. When disinfection is required, the three-way gun body 1 is separated from the connecting component 3, and then the three-way gun body 1 is disinfected. Moreover, the connecting component 3 can also be connected to a high-speed mobile phone for stomatology, and there is no need to add a new interface on the pipeline of the dental treatment instrument to connect to the high-speed mobile phone.

[0033] like Figure 3 As shown, the inner side wall of the connecting ring 32 is provided with a sliding groove 321 , and the limiting ring 33 is slidably installed in the sliding groove 321 .

[0034] Specifically, the limiting ring 33 is disposed in the sliding groove 321 , which can prevent the connecting ring 32 from being separated from the docking housing 31 and does not affect the rotation of the connecting ring 32 .

[0035] like Figure 4 As shown, the outer side wall of the connecting ring 32 is provided with a groove 322 , and a plurality of anti-slip protrusions are provided in the groove 322 .

[0036] Specifically, the anti-slip protrusions provided in the groove 321 can increase the friction between the user and the connecting ring 32, thereby avoiding slipping when rotating the connecting ring 32, and allowing the user to quickly rotate the connecting ring 32 when disassembling the spray gun.

[0037] like Figure 3 As shown, a control valve body is provided in the three-purpose gun body 1, and a flow channel connected to the nozzle 2 is provided on the control valve body. The other end of the flow channel away from the nozzle 2 is connected to at least one first pipe joint 11, and at least one control button 12 is provided on the control valve body. Each of the control buttons 12 passes through the three-purpose gun body 1 and extends to the external setting. Each of the control buttons 12 controls the opening or closing of one of the first pipe joints 11.

[0038] In this embodiment, two control buttons 12 are provided on the control valve body, which respectively control the two first pipe connectors 11. The two control buttons 12 respectively control the two first pipe connectors 11 to transport gas or water into the flow channel. When the user presses the two control buttons 12 at the same time, the two first pipe connectors 11 respectively transport gas and water into the flow channel, so that the nozzle 2 sprays out gas and water at the same time to clean the teeth.

[0039] like Figure 3 and 4 As shown, a docking seat 34 is disposed in the docking housing 31 , and at least one second pipe connector 35 that cooperates with the first pipe connector 11 is disposed on the docking seat 34 .

[0040] In this embodiment, two second pipe connectors 35 are provided on the docking seat 34, which are respectively connected to an external gas source and a water source. When the second pipe connector 35 and the first pipe connector 11 are connected together, the gas and water flow to the corresponding first pipe connector 11 through the corresponding second pipe connector 35 respectively.

[0041] like Figure 3 and 4 As shown, the butt joint ends of the first pipe connector 11 and the second pipe connector 35 that cooperate with each other are both quick connectors.

[0042] Specifically, the butt joint ends of the first pipe connector 11 and the second pipe connector 35 adopt quick connectors, which can facilitate the connection and separation of the first pipe connector 11 and the second pipe connector 35. When the butt joint shell 31 is butt jointed with the second end of the three-purpose gun body 1, the first pipe connector 11 and the second pipe connector 35 can be quickly connected so that the first pipe connector 11 and the second pipe connector 35 are connected.

[0043] like Figure 3 and 4 As shown, the three-purpose gun body 1, the first pipe connector 11 and the control button 12 are all made of copper material.

[0044] Specifically, during the use of the three-purpose gun body 1, medical staff need to hold the three-purpose gun body 1 and press the control button 12 for control, so bacteria will remain on the three-purpose gun body 1 and the control button 12. Copper is cheap and has good bactericidal and antibacterial effects. Cooperating with an external sterilization device can be more conducive to killing the bacteria remaining on the three-purpose gun body 1, the first pipe connector 11 and the control button 12, and the three-purpose gun body 1 has a good service life.

[0045] like Figure 3 and 4 As shown, the external thread and the internal thread are both British threads.

[0046] Specifically, in order to facilitate the export and sale of the three-way gun, both the external thread and the internal thread adopt the internationally common British thread, which can facilitate the manufacture and promotion of the three-way gun.

[0047] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
