Embodiment 1, referring to fig. 1, 2 and 3, there is provided a portable dental three-purpose gun apparatus comprising: the spray gun comprises a hand-held handle 100, a spray gun head 200, a spray switch 210, a gas injection switch 220, a gas compressing device 300, a liquid storage tank 206, a first one-way valve 203, a second one-way valve 204, a first pipeline 205 and a second pipeline 202, wherein the spray gun head 200 is provided with a nozzle, the nozzle is provided with a gas inlet 211, a liquid inlet 222 and a total outlet 223, and the total outlet 223 is communicated with the gas inlet 211 and the liquid inlet 222; an accommodating cavity is formed in the hand grip 100, an opening of the accommodating cavity is hermetically connected with the lower part of the spray gun head 200, the liquid storage tank 206 is arranged in the accommodating cavity, an air pressure chamber is formed between the outer wall of the liquid storage tank 206 and the inner wall of the accommodating cavity, the air pressing device 300 is arranged in the spray gun head 200, an air output end of the air pressing device 300 is communicated with the air pressure chamber through a first one-way valve 203, and a valve of the first one-way valve 203 is opened in a one-way manner from the air output end of the air pressing device 300 to the air pressure chamber; the liquid storage tank 206 is provided with a liquid outlet, a liquid storage chamber and an air inlet, the liquid outlet and the air inlet are respectively communicated with the liquid storage chamber, the liquid outlet is communicated with the input end of a liquid spraying switch 210 through a first pipeline 205, the air pressure chamber is communicated with the input end of an air spraying switch 220 through a second pipeline 202, the output end of the liquid spraying switch 210 is communicated with a liquid inlet 222 through a pipeline, and the output end of the air spraying switch 220 is communicated with a gas inlet 211 through a pipeline; the air inlet is connected with the air pressure chamber in a one-way mode through a second one-way valve 204, and a valve of the second one-way valve 204 is opened from the air pressure chamber to the liquid storage chamber in a one-way mode.

The portable dental three-purpose gun device is arranged to realize the function of the three-purpose gun in an independent device mode. For this reason, the portable dental triple-purpose gun device needs to take the factors of a liquid source and an air source into consideration. Of course, in order to make the three-way gun apparatus capable of performing the functions of spraying, jetting and misting, it is necessary to consider a certain pressure for the liquid source and the gas source.

With respect to the fluid source, the fluid source may be addressed by providing a fluid reservoir 206 and then placing a quantity of fluid (e.g., water) within the fluid reservoir 206. The air supply is considered to be a solution to the problem of air supply by forming an air pressure chamber between the outer wall of the reservoir 206 and the interior of the receiving cavity through which air is stored.

Besides the problems of liquid source and air source, the pressure problem of liquid source and air source also needs to be solved. For this reason, this portable three way gun device for dentistry through setting up aerostatics device 300, the user can be through pressing aerostatics device 300, extrudes the air through aerostatics device 300 to the atmospheric pressure room. Because the air pressure chamber is communicated with the air compressing device 300 through the first one-way valve 203, the air output by the air compressing device 300 is extruded into the air pressure chamber. The air pressure of the air pressure chamber is increased by the extrusion of the air compressing device 300, so that the air pressure is provided for the air source.

The liquid storage tank 206 is provided with an air inlet which is communicated with the liquid storage chamber through a second one-way valve 204. Thus, the high pressure gas in the pressure chamber acts on the liquid storage chamber through the gas inlet. Thereby providing pressure to the liquid in the liquid storage chamber and solving the pressure problem of the liquid source.

In order to solve the pressure problem of the gas source and the liquid source, the embodiment pressurizes the gas pressure chamber, and then pressurizes the liquid source by using the gas pressurized by the gas pressure chamber. The pressure problem of the liquid source and the air source is solved skillfully by only pressurizing the air source. Provides a structural basis for realizing the functions of liquid spraying, air spraying and spraying.

When the portable dental triple-purpose gun device works, a user presses the liquid spraying switch 210 when the liquid spraying function is needed. At this time, the first pipe 205 is communicated with the external environment through the main outlet 223 of the nozzle, since the air pressure of the pneumatic chamber is greater than that of the external environment. Therefore, under the action of the pressure difference, the gas extrudes the liquid in the liquid storage chamber, so that the liquid in the liquid storage chamber flows out through the liquid outlet. Liquid enters the liquid inlet 222 of the nozzle through the first conduit 205 and is then ejected from the main outlet 223 of the nozzle, thereby performing a liquid ejection function.

When the air injection function is required, the user presses the air injection switch 220. At this time, the second pipe 202 communicates with the external environment through the total outlet 223 of the nozzle, since the air pressure of the pneumatic chamber is greater than that of the external environment. Therefore, the gas enters the gas inlet 211 of the nozzle through the second pipe 202 and is then ejected from the overall outlet 223 of the nozzle by the pressure difference, thereby performing the gas injection function.

When it is desired to perform the spraying function, the user can press the spray switch 210 and the air injection switch 220 at the same time. Under the pressure of the pneumatic chamber, both the liquid and the gas are ejected towards the main outlet 223 of the nozzle. The liquid and the gas interact to form mist, and the function of spraying is realized.

The portable dental three-purpose gun device integrates a liquid source and an air source through the arrangement structure. Meanwhile, the air compressing device 300 is utilized to realize manual pressurization of the air source. Through the structure mode, the liquid spraying function, the air spraying function and the spraying function are realized. Moreover, the whole device has independent functions, gets rid of the constraint of the dental comprehensive therapeutic apparatus, and realizes the portability and the mobility of the three-purpose gun.

In some preferred embodiments, the portable dental triple-purpose gun apparatus further comprises a nozzle 400, the nozzle 400 being in communication with the main outlet 223. The overall outlet 223 may be extended by the nozzle 400 to spray at specific locations to facilitate spraying.

In some preferred embodiments, the opening of the accommodating cavity is provided with internal threads, and the lower portion of the lance head 200 is provided with external threads, and the internal threads are in threaded connection with the external threads. The hand grip 100 and the nozzle 400 are detachable from each other by providing internal and external threads.

In some preferred embodiments, the portable dental triple-purpose gun device further comprises a sealing ring (not shown), the lower portion of the gun head 200 is provided with an abutting edge, the abutting edge is located at the tail end of the external thread, the sealing ring is sleeved with the external thread, and the upper edge of the opening of the accommodating cavity is in compression joint with the abutting edge through the sealing ring. By adding the sealing ring, the air tightness of the accommodating cavity can be improved.

In some preferred embodiments, the inlet of the second check valve 204 is provided with a stepped structure for facilitating the insertion and extraction of the second pipe 202. The stepped structure is arranged at the inlet of the second one-way valve 204, so that the second pipeline 202 can be conveniently plugged and pulled out, and the second pipeline 202 can be conveniently maintained and replaced in the future.
