[0007] Preferably, telescopic rods with telescopic ends fixed to the bottom of the support plate are installed at both ends of the top of the base, and springs arranged on the outside of the telescopic rods are installed at both ends of one end of the base opposite to the support plate.

[0008] Preferably, a second thread groove is provided at the top center of the base, the internal thread of the second thread groove is connected to a threaded rod, and the top of the threaded rod is rotatably connected to the bottom center of the support plate.

[0009] Preferably, a clamping hole is provided at the center of the top of the threaded sleeve rod to form a clamping structure with the cleaning needle.

[0010] Preferably, a two-way pipe is installed at the bottom center of the first thread groove, and a transport pipe is connected to the top of the two-way pipe and passes through the inside of the cleaning needle.

[0011] Preferably, first openings are formed at both ends of the outer wall of the cleaning needle, second openings are formed at the front and rear ends of the outer wall of the cleaning needle, and the first opening and the second opening have different heights.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model can connect an external water source with a two-way pipe through an opening, and then the external water source is transported to the inside of the cleaning needle through a transport pipe and then sprayed through the needle head for oral cleaning. The support plate can move up and down relative to the base through the arranged telescopic rod and spring, and the support plate can be adjusted to move up and down by rotating the threaded rod and the second threaded groove threaded connection, so that the needle head of the cleaning needle can be extended to a deeper part of the oral cavity. The depth of the cleaning needle entering the patient's oral cavity can be adjusted without changing the size of the cleaning needle, so as to meet the needs of more patients.

[0014] The utility model provides a clamping hole at the top center of the threaded sleeve rod, which can be used to disassemble and fix the cleaning needle, thereby realizing replacement of the cleaning needle and reducing secondary infection of the patient. When the needle head of the cleaning needle is blocked, water can be discharged for cleaning through the first opening and the second opening. Moreover, the first opening and the second opening are set at different heights, so that the possibility of blockage together is greatly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.

[0022] See also Figure 1-4 A needle assembly for oral irrigation includes a base 1, a support plate 2 that can move up and down is connected to the top of the base 1, a mounting seat 3 is connected to the top of the support plate 2, a first thread groove 4 is opened inside the mounting seat 3, a threaded sleeve rod 5 is installed inside the first thread groove 4, a cleaning needle 6 that passes through the top of the mounting seat 3 is connected to the top of the threaded sleeve rod 5, and an opening 301 is opened at the bottom of one end of the mounting seat 3.

[0023] like Figure 1-4 As shown, telescopic rods 7 with telescopic ends fixed to the bottom of the support plate 2 are installed at both ends of the top of the base 1, and springs 8 arranged on the outside of the telescopic rods 7 are installed at both ends of the base 1 opposite to the support plate 2. The support plate 2 can move up and down relative to the base 1 through the arrangement of the telescopic rods 7 and the springs 8.

[0024] like Figure 1-4As shown, a second thread groove 9 is provided at the top center of the base 1, and a threaded rod 10 is connected to the internal thread of the second thread groove 9. The top of the threaded rod 10 is rotatably connected to the bottom center of the support plate 2. The up and down movement of the support plate 2 can be adjusted by threading the threaded rod 10 and the second thread groove 9.

[0025] like Figure 1-4 As shown, a clamping hole 11 is opened at the top center of the threaded sleeve 5 to form a clamping structure with the cleaning needle 6. The cleaning needle 6 can be disassembled and fixed by opening the clamping hole 11 at the top center of the threaded sleeve 5, so that the cleaning needle 6 can be replaced.

[0026] like Figure 1-4 As shown, a two-way pipe 12 is installed at the bottom center of the first threaded groove 4, and a transport pipe 13 is connected to the top of the two-way pipe 12 and passes through the inside of the cleaning needle 6. An external water source can be connected to the two-way pipe 12 through the opening 301, and then the external water source is transported to the inside of the cleaning needle 6 through the transport pipe 13 and then sprayed through the needle for oral cleaning.

[0027] like Figure 1-4 As shown, first openings 14 are provided at both ends of the outer wall of the cleaning needle 6, and second openings 15 are provided at the front and rear ends of the outer wall of the cleaning needle 6, and the heights of the first opening 14 and the second opening 15 are different. When the needle head of the cleaning needle 6 is blocked, water can be discharged for cleaning, and the different heights of the first opening 14 and the second opening 15 greatly reduce the possibility of being blocked together.

[0028] Working principle: When in use, the external water source can be connected to the two-way pipe 12 through the opening 301, and then the external water source is transported to the inside of the cleaning needle 6 through the transport pipe 13 and then sprayed through the needle head for oral cleaning. The support plate 2 can move up and down relative to the base 1 through the telescopic rod 7 and the spring 8, and the up and down movement of the support plate 2 can be adjusted by rotating the threaded rod 10 and the second threaded groove 9, so that the needle head of the cleaning needle 6 extends deeper into the oral cavity. The depth of the cleaning needle 6 entering the patient's oral cavity can be adjusted without changing the size of the cleaning needle 6 to meet the needs of more patients. The cleaning needle 6 can be disassembled and fixed by opening a clamping hole 11 at the top center of the threaded sleeve 5, so that the cleaning needle 6 can be replaced, reducing the secondary infection of the patient. When the needle head of the cleaning needle 6 is blocked, water can be discharged for cleaning through the first opening 14 and the second opening 15, and the possibility of being blocked together is greatly reduced by the different heights of the first opening 14 and the second opening 15.
