In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] As Figures 1 to 5 shown, the oral irrigation device of the embodiment of the present utility model includes a triple-purpose syringe 1, a connecting tube 2 and a quick-release assembly 3. The triple-purpose syringe 1 is detachably connected to the connecting tube 2 through the quick-release assembly 3. The quick-release assembly 3 includes a connecting seat 31 and a screw sleeve 32. A first liquid channel 315 and a first gas channel are provided on the connecting seat 31. The first liquid channel 315 is used to connect to an external water source through the connecting tube 2, and the first gas channel communicates with an external gas source through the connecting tube 2. An inlet liquid tube and an inlet gas tube are provided in the connecting tube 2. The first liquid channel 315 is used to connect to an external water source through the inlet liquid tube, and the first gas channel communicates with an external gas source through the inlet gas tube. The triple-purpose syringe 1 is provided with a second liquid channel 11 and a second gas channel 12. The screw sleeve 32 is movably connected to the connecting seat 31. A first thread 321 is provided on the inner side surface of the screw sleeve 32, and a second thread 13 is provided on the outer peripheral wall of the triple-purpose syringe 1. The first thread 321 is connected to the second thread 13 so that the triple-purpose syringe 1 is pressed against the connecting seat 31. The first liquid channel 315 communicates with the second liquid channel 11, and the first gas channel communicates with the second gas channel 12.

[0032] It can be understood that, through the detachable setting of the triple-purpose gun 1 and the connecting pipe 2, it is convenient to disassemble and replace the triple-purpose gun 1 to avoid cross-infection, improve the use safety of the triple-purpose gun 1, reduce the use of traditional anti-contamination films to reduce material waste, and thus reduce the cost of oral treatment; by using the screw sleeve 32 to be threadedly connected with the triple-purpose gun 1, the connection is stable, and only by screwing the screw sleeve 32 to lock the first thread 321 and the second thread 13, the connection seat 31 fixedly connected with the connecting pipe 2 is tightened against the triple-purpose gun 1 to complete the installation of the triple-purpose gun 1. Unscrewing the screw sleeve 32 to separate it from the triple-purpose gun 1 can realize the disassembly of the triple-purpose gun 1, and the disassembly and assembly are convenient. In addition, it should be noted that the whole triple-purpose gun 1 is made of high-temperature resistant materials, such as stainless steel, etc., which is convenient for high-temperature sterilization of the triple-purpose gun 1 after disassembly for subsequent use, and further improves the use safety of the triple-purpose gun 1.

[0033] Optionally, as Figure 5 shown, the screw sleeve 32 includes a sleeve portion 322 and a clamping portion 323. The inner side wall of the sleeve portion 322 is annularly protruded along its own central axis direction with the clamping portion 323. The sleeve portion 322 is sleeved on the outer periphery of the connection seat 31. The inner side wall of the sleeve portion 322 is provided with a first thread 321. The outer peripheral wall of the connection seat 31 is annularly recessed along its own central axis direction with a clamping groove 314. The clamping portion 323 is inserted into the clamping groove 314. Through the cooperative setting of the clamping portion 323 and the clamping groove 314, the clamping portion 323 is always located in the clamping groove 314 and can rotate relative to the sliding groove, that is, the connection stability between the screw sleeve 32 and the connection seat 31 is ensured. Of course, on the premise that the connection seat 31 does not have the clamping groove 314, the clamping portion 323 is located on the side of the connection seat 31 away from the triple-purpose gun 1. When installing the triple-purpose gun 1, screw the screw sleeve 32 to clamp the connection seat 31 between the clamping portion 323 and the triple-purpose gun 1, so as to complete the abutment between the connection seat 31 and the triple-purpose gun 1.

[0034] Furthermore, as Figure 2 and Figure 3 shown, a gas guide pipe 14 and a liquid guide pipe 15 are protruded on one side of the triple-purpose gun 1 facing the connection seat 31. The gas guide pipe 14 is communicated with the second gas channel 12, and the liquid guide pipe 15 is communicated with the second liquid channel 11. A gas guide groove 311 and a liquid guide groove 312 are recessed on one side of the connection seat 31 facing the triple-purpose gun 1. The gas guide groove 311 is communicated with the first gas channel, and the liquid guide groove 312 is communicated with the first liquid channel 315. The gas guide pipe 14 is inserted into the gas guide groove 311, and the liquid guide pipe 15 is inserted into the liquid guide groove 312. Through the cooperation of the gas guide pipe 14 and the gas guide groove 311, and the liquid guide pipe 15 and the liquid guide groove 312, the connection accuracy between the first gas channel and the second gas channel 12, the first liquid channel 315 and the second liquid channel 11 can be improved, thereby improving the installation accuracy of the triple-purpose gun 1 and the connection seat 31.

[0035] Even further, as Figure 2As shown, the oral irrigation device further includes a gasket 4, which is disposed between the triple-purpose syringe 1 and the connecting seat 31. By providing the gasket 4, the sealing performance between the triple-purpose syringe 1 and the connecting seat 31 is effectively enhanced, and the leakage of gas or liquid is reduced.

[0036] Preferably, the gasket 4 includes a first sealing portion 41 disposed between the triple-purpose syringe 1 and the connecting seat 31. The first sealing portion 41 is provided with an air guide hole 42 corresponding to the position of the air guide groove 311. A second sealing portion 43 is protrudingly provided on the side of the first sealing portion 41 facing the connecting seat 31, and the second sealing portion 43 is annularly arranged around the outer edge of the air guide hole 42. The second sealing portion 43 can be sleeved on the outer periphery of the air guide tube 14 and inserted into the air guide groove 311. The first sealing portion 41 is provided with a liquid guide hole 44 corresponding to the position of the liquid guide groove 312. A third sealing portion 45 is protrudingly provided on the side of the first sealing portion 41 facing the connecting seat 31, and the third sealing portion 45 is annularly arranged around the outer edge of the liquid guide hole 44. The third sealing portion 45 can be sleeved on the outer periphery of the liquid guide tube 15 and inserted into the liquid guide groove 312. By inserting the second sealing portion 43 into the air guide groove 311 and the third sealing portion 45 into the liquid guide groove 312, the installation accuracy of the gasket 4 can be improved, and the gasket 4 can be prevented from shifting during installation or extrusion, thereby affecting the sealing performance between the triple-purpose syringe 1 and the connecting seat 31.

[0037] Certainly, the second sealing portion 43 is sleeved on the outer periphery of the air guide tube 14 and inserted into the air guide groove 311, which can improve the connection sealing performance between the air guide tube 14 and the air guide groove 311, thereby ensuring the connection sealing performance of the first gas passage and the second gas passage 12. The third sealing portion 45 is sleeved on the outer periphery of the liquid guide tube 15 and inserted into the liquid guide groove 312, which can improve the connection sealing performance between the liquid guide tube 15 and the liquid guide groove 312, thereby ensuring the connection sealing performance of the first liquid passage 315 and the second liquid passage 11.

[0038] In some embodiments, an anti-fooling post 16 is further protrudingly provided on one side of the triple-purpose gun 1 facing the connecting seat 31, and an anti-fooling groove 313 is recessedly provided on one side of the connecting seat 31 facing the triple-purpose gun 1. The anti-fooling post 16 is inserted into the anti-fooling groove 313. Through the cooperation of the anti-fooling post 16 and the anti-fooling groove 313, the installation accuracy of the triple-purpose gun 1 and the connecting seat 31 can be improved, and the situation where the air guide tube 14 is inserted into the diversion groove 312 and the diversion tube 15 is inserted into the air guide groove 311 can be avoided. It should be noted that the connection lines of the anti-fooling post 16, the air guide tube 14, and the diversion tube 15 are distributed in a triangular shape. Of course, the size of the anti-fooling post 16 can also be set to be different from that of the air guide tube 14 and the diversion tube 15. In addition, in other embodiments, the connection line of the air guide tube 14 and the diversion tube 15 can also be spaced from the central axis of the triple-purpose gun 1. When the medical staff inserts the triple-purpose gun 1 into the connecting seat 31, if the air guide tube 14 is inserted into the diversion groove 312 and the diversion tube 15 is inserted into the air guide groove 311, the outer periphery of the triple-purpose gun 1 and the outer periphery of the connecting seat 31 will deviate from each other, and at this time, the screw sleeve 32 cannot be screwed.

[0039] In addition, it is not limited to setting the anti-fooling post 16 on the side of the triple-purpose gun 1 facing the connecting seat 31 and setting the anti-fooling groove 313 on the side of the connecting seat 31 facing the triple-purpose gun 1. It is also possible to set the anti-fooling post 16 on the side of the triple-purpose gun 1 facing the connecting seat 31 and set the anti-fooling groove 313 on the side of the connecting seat 31 facing the triple-purpose gun 1. Similarly, it is not limited to setting the air guide tube 14 and the diversion tube 15 on the side of the connecting seat 31 facing the triple-purpose gun 1 and setting the diversion groove 312 and the air guide groove 311 on the side of the connecting seat 31 facing the triple-purpose gun 1. It is also possible to set the diversion groove 312 and the air guide groove 311 on the side of the connecting seat 31 facing the triple-purpose gun 1 and set the diversion tube 15 and the air guide tube 14 on the side of the connecting seat 31 facing the triple-purpose gun 1. Of course, it is also possible to set the air guide tube 14 and the diversion groove 312 on the side of the connecting seat 31 facing the triple-purpose gun 1, and set the diversion tube 15 and the air guide groove 311 on the side of the triple-purpose gun 1 facing the connecting seat 31.

[0040] Furthermore, as Figure 2 and Figure 3 shown, a first magnet 5 is provided on the anti-fooling post 16, and a second magnet is provided at the bottom of the anti-fooling groove 313. The first magnet 5 and the second magnet attract each other, that is, the first magnet 5 and the second magnet are two magnets with opposite magnetic polarities. The connection of the triple-purpose gun 1 and the connecting seat 31 requires the cooperation of multiple people. That is, one operator abuts and stabilizes the triple-purpose gun 1 and the connecting seat 31, and another operator screws the screw sleeve 32. In this embodiment, through the setting of the first magnet 5 and the second magnet, pre-fixation can be carried out when the two flanges are connected, and one person can complete the connection of the flanges, reducing the input of operators and facilitating the connection.

[0041] In other embodiments, the three-in-one gun 1 includes a gun body 17, a nozzle 18, a jet button 19 and a water spray button 20. A mixing chamber is provided inside the gun body 17. The nozzle 18 is provided on the gun body 17, and the inner channel of the nozzle 18 communicates with the mixing chamber. At one end of the gun body 17 away from the nozzle 18, a second liquid channel 11 and a second gas channel 12 communicating with the mixing chamber are further provided. A jet button 19 for controlling the opening and closing of the second gas channel 12 and a water spray button 20 for controlling the opening and closing of the second liquid channel 11 are movably provided on the gun body 17.

[0042] It can be understood that the gun body 17 is detachably connected to the connecting seat 31. By pressing the jet button 19 alone, the second gas channel 12 is communicated with the mixing chamber, and high-pressure jetting of the nozzle 18 can be achieved. By pressing the water spray button 20 alone, the second liquid channel 11 is communicated with the mixing chamber, and high-pressure liquid spraying of the nozzle 18 can be achieved. By pressing the jet button 19 and the water spray button 20 simultaneously, both the second gas channel 12 and the second liquid channel 11 are communicated with the mixing chamber, so that high-pressure gas and high-pressure liquid are mixed in the mixing chamber and high-pressure water mist is ejected from the nozzle 18. This structure is simple and convenient to use.

[0043] Furthermore, the jet button 19 can only control the opening and closing of the second gas channel 12 and cannot control the magnitude of the flowing air pressure in the second gas channel 12. Medical staff can only control the magnitude of the flowing air pressure by controlling the output power of the external air source, and the operation is complicated. Therefore, a pressure regulating component is further provided on the connecting seat 31. The pressure regulating component includes a first sphere, a first valve rod and a first knob. The first sphere is arranged in the first gas channel. The first valve rod is rotatably arranged on the connecting seat 31, and one end of the first valve rod is connected to the first sphere. The first sphere is provided with a first communication hole, and the central axis of the first communication hole is arranged at an angle to the rotation axis of the first valve rod. The end of the first valve rod away from the first sphere extends outside the connecting seat 31 and is connected to the first knob. By screwing the first knob to drive the rotation of the first valve rod on the first sphere, the adjustment of the penetration size of the first communication hole and the first gas channel is realized, so as to realize the adjustment of the magnitude of the flowing air pressure in the air flow channel, and the operation is simple.

[0044] Optionally, as Figure 4 and Figure 5As shown, the water spray button 20 can only control the opening and closing of the second liquid channel 11, but cannot control the magnitude of the flowing hydraulic pressure in the second liquid channel 11. Medical staff can only control the magnitude of the flowing hydraulic pressure by controlling the output power of the external water source, and the operation is complicated. Therefore, a hydraulic pressure regulating assembly 6 is provided on the connecting seat 31. The hydraulic pressure regulating assembly 6 includes a second sphere 64, a second valve rod 63 and a second knob. The second sphere 64 is disposed in the first liquid channel 315. The second valve rod 63 is rotatably disposed on the connecting seat 31, and one end of the second valve rod 63 is connected to the second sphere 64. The second sphere 64 is provided with a second communication hole 641. The central axis of the second communication hole 641 is disposed at an angle to the rotation axis of the second valve rod 63. The end of the second valve rod 63 away from the second sphere 64 extends outside the connecting seat 31 and is connected to the second knob. By screwing the second knob to drive the rotation of the second valve rod 63 on the second sphere 64, the adjustment of the penetration magnitude between the second communication hole 641 and the first liquid flow channel is realized, so as to realize the adjustment of the magnitude of the flowing hydraulic pressure in the liquid channel, and the operation is simple. Of course, in some embodiments, an air pressure regulating assembly and the hydraulic pressure regulating assembly 6 can be provided at the same time to regulate both the air flow channel and the liquid channel.

[0045] In addition, the external water source can be pure water or a cleaning liquid containing anti-inflammatory and bactericidal drugs.

[0046] Furthermore, an internal gear ring 61 is provided on the connecting seat 31. The second knob includes a gear 62. The second valve rod 63 includes a first support rod 631 and a second support rod 632. The first support rod 631 is rotatably connected to the connecting seat 31, and one end of the first support rod 631 is connected to the second sphere 64. The second support rod 632 is provided with a chute. One end of the first support rod 631 away from the second sphere 64 is provided with a first anti-rotation plane 6311. The chute is provided with a second anti-rotation plane corresponding to the first anti-rotation plane 6311. One end of the first support rod 631 away from the second sphere 64 is inserted into the chute, and the first anti-rotation plane 6311 abuts against the second anti-rotation plane. One end of the second support rod 632 away from the first support rod 631 is provided with a gear 62. The second support rod 632 is slidably disposed on the connecting seat 31 along the rotation axis direction of the gear 62, and the gear 62 can be engaged with the internal gear ring 61.

[0047] It should be noted that one end of the first rod 631 away from the second sphere 64 is always inserted into the chute. Through the cooperation of the first anti-rotation and the second anti-rotation planes, it can avoid slipping when the first rod 631 and the second rod 632 rotate relative to each other. By way of example, the cross-section of the end of the first rod 631 away from the second sphere 64 is quadrilateral, and the corresponding chute is also quadrilateral. Then, the four side surfaces of the end of the first rod 631 away from the sphere are all the first anti-rotation planes 6311, and the four groove walls of the chute are also the second anti-rotation planes. Of course, it is not limited to setting one, two, three, four or even more anti-rotation planes. The setting of the anti-rotation planes effectively ensures the installation stability between the first rod 631 and the second rod 632.

[0048] In addition, during adjustment, only the gear 62 needs to be pulled out from the internal gear ring 61, and the gear 62 is rotated to drive the second rod 632, thereby driving the first rod 631 and the second sphere 64 to rotate, so as to adjust the communication size between the communication hole and the channel. After the adjustment is completed, the gear 62 is inserted into the internal gear ring 61. By using the meshing of the internal gear ring 61 and the gear 62, the stability of the gear 62 can be ensured, and it can avoid the sphere from driving the valve rod to rotate under high-pressure impact, effectively ensuring the structural stability of the adjustment assembly. It should be noted that the air pressure adjustment assembly has the same structure as this hydraulic adjustment assembly 6.
