[0025] like Figure 1 As shown, a head structure of a high-definition visual oral irrigator includes an endoscope housing 1, a spray bar 2, an endoscope module 3 located inside the endoscope housing 1, and a nozzle 4. The spray bar 2 includes a spray bar body 21 connected to the nozzle 4 and a spray bar connecting portion 22 located at the lower end of the spray bar body 21. A mounting portion 11 is provided at the bottom of the endoscope housing 1, and a positioning hole 111 is provided on the mounting portion 11 for positioning the spray bar connecting portion 22. A spray bar mounting seat 5 is connected to the bottom surface of the mounting portion 11, and a water inlet 6 is provided on the spray bar mounting seat 5, located directly below the positioning hole 111. The lower end of the spray bar connecting portion 22 can be sealed and plugged into the water inlet 6. A locking component 7 is provided at the water inlet 6 for locking the spray bar connecting portion 22.

[0026] Specifically, in this embodiment, the spray bar mounting base 5 includes an upper base 51 and a lower base 52 connected vertically; wherein, the water inlet 6 is located on the lower base 52; the upper base 51 is connected to the mounting part 11 by a locking screw 8, a locking assembly 7 is disposed on the upper base 51, and the upper base 51 has a clearance hole for exposing the water inlet 6. Furthermore, a sealing ring is provided inside the water inlet 6 to prevent water leakage at the connection.

[0027] In this embodiment, the locking assembly 7 includes a locking block 71 with a through hole 711. The locking block 71 is horizontally slidably connected to the upper seat 51, and the through hole 711 is located between the positioning hole 111 and the water inlet 6. An elastic element 72 is provided between one end of the locking block 71 and the upper seat 51, and a switching push button 73 is connected to the other end of the locking block 71. Preferably, the elastic element 72 is a spring sleeved on the guide rod 712; a guide rod 712 is provided at one end of the locking block 71 to guide the spring to extend and retract along the sliding direction of the locking block 71.

[0028] Furthermore, the upper seat 51 is provided with two guide blocks 53 for guiding the lock block 71 to slide linearly, and one end of the guide block 53 is provided with a limiting part 531 for limiting the switching push button 73.

[0029] In use, press the switching push button 73 to make the locking block 71 move horizontally relative to the upper seat 51 after overcoming the elastic force of the elastic element 72, so that the through hole 711 passes through the positioning hole 111 and the water inlet 6, so that the lower end of the spray bar connecting part 22 can be inserted into the water inlet 6; after the insertion is completed, release the switching push button 73, and the locking block 71 will reset under the elastic force of the elastic element 72, thereby locking the spray bar connecting part 22.

[0030] In this embodiment, the lower end of the spray bar body 21 is provided with an end limiting surface for limiting the insertion of the spray bar 2. A mutually fitting positioning surface 10 is provided between the spray bar body 21 and the endoscope housing 1, which can guide the accurate insertion and removal of the spray bar 2 and helps improve the structural strength of the head structure. Preferably, the sliding direction of the locking block 71 is perpendicular to the positioning surface 10.

[0031] Furthermore, a sliding guide structure is provided between the two positioning surfaces 10 to improve the insertion accuracy of the spray bar 2. In this embodiment, the sliding guide structure includes a protrusion 211 provided on the positioning surface 10 of the spray bar body 21 and a sliding groove provided on the positioning surface 10 of the endoscope housing 1, wherein the protrusion 211 can slide up and down into or out of the sliding groove.

[0032] In this embodiment, the upper and lower ends of the spray bar body 21 are set at an included angle. Preferably, the included angle between the upper and lower ends of the spray bar body 21 can be 90° or 120°, etc. The high-definition visual oral irrigator can be equipped with multiple spray bars 2, each spray bar 2 having a spray bar connecting part 22 with the same structure. During use, the appropriate spray bar 2 can be selected according to the required rinsing location.

[0033] This invention discloses a head structure for a high-definition visual oral irrigator. During use, the lower end of the spray bar connecting part 22 passes through the positioning hole 111 and is sealed and inserted into the water inlet 6, and locked by the locking assembly 7. When the spray bar 2 needs to be replaced, first release the locking assembly 7 from the spray bar connecting part 22, pull out the spray bar 2, and replace it with a new one. Therefore, it is compatible with spray bars 2 of different specifications. This invention also connects to the spray bar mounting base 5 via the mounting part 11. The positioning hole 111 on the mounting part 11 is used to position the spray bar connecting part 22. The locking assembly 7 is installed between the positioning hole 111 and the water inlet 6, thereby achieving a better and more stable connection between the spray bar 2 and the endoscope housing 1, which is beneficial for improving the oral irrigation effect.
