[0077] Embodiment 1

[0078] As Figure 1 and Figure 2 shown, the oral irrigation device of this embodiment includes an irrigation working tip 1, a protective sleeve 2, an angle adjustment device 3, a first connecting rod 4, an eccentric shaft 5, a second connecting rod 6, an oscillation device 7, a housing 8, an oscillation intensity adjustment chip module 9, and a control button 10. In some embodiments, the oral irrigation device of this embodiment further includes a rechargeable battery 11 and a charging socket 12.

[0079] As Figure 3 shown, the angle adjustment device 3 includes a fixed housing 301 and a rotating component 302. The outer contour of the fixed housing 301 is a sphere or a spherical-like shape. The fixed housing 301 is a hollow structure, which forms a cavity and has an opening. The outer surface of the rotating component 302 has a convex curved surface. At least a part of the rotating component 302 is located inside the cavity of the fixed housing 301. The concave curved surface inside the cavity of the fixed housing 301 can partially fit with the convex curved surface of the outer surface of the rotating component 302. The opening of the fixed housing 301 can accommodate the rotation angle of the rotating component 302. The opening of the fixed housing 301 should not be too large, otherwise it is not conducive to the stable fitting of the fixed housing 301 and the rotating component 302, and is not conducive to maintaining the stability of the irrigation working tip 1 during operation.

[0080] As Figure 4As shown in the figure, the opening of the fixed housing 301 has a first opening edge 30111, a second opening edge 30112, a third opening edge 30113, and a fourth opening edge 30114. The first opening edge 30111 and the second opening edge 30112 are oppositely arranged, and the third opening edge 30113 and the fourth opening edge 30114 are oppositely arranged. The included angle between the plane formed by the third opening edge 30113 and the center of the fixed housing 301 and the plane formed by the fourth opening edge 30114 and the center of the fixed housing 301 is about 60°. In this way, it can not only meet the rotation angle of the rotating member 302, but also enable the rotating member 302 to stably fit with the fixed housing 301, ensuring the stability of the flushing working tip 1 during operation.

[0081] A first fixing mechanism 3012 and a first track 3013 are arranged in the cavity of the fixed housing 301.

[0082] A first fixing mechanism groove is arranged in the fixed housing 301. The first fixing mechanism 3012 is connected to the first fixing mechanism groove through an elastic member. The elastic member can be a spring. When the elastic member is in the first compression state, the first fixing mechanism 3012 is located in the first fixing mechanism groove. In this embodiment, the first fixing mechanism 3012 is a tenon head. The tenon head is hemispherical.

[0083] In this embodiment, three first fixing mechanisms 3012 are provided. Each first fixing mechanism 3012 is respectively provided with a first fixing mechanism groove. The three first fixing mechanisms 3012 are arranged along the length direction of the first opening edge 30111. Of course, the number of the first fixing mechanisms 3012 can be set arbitrarily. In a certain area, the more the number of the first fixing mechanisms 3012 is set, the smaller the minimum adjustable angle of the flushing working tip 1 is, and the higher the adjustment accuracy is, but the adjustment resistance will increase. When the number of the first fixing mechanisms 3012 is fixed, the larger the area where the first fixing mechanisms 3012 are distributed, the larger the adjustable range of the flushing working tip 1 is, and the larger the minimum adjustable angle is.

[0084] The first track 3013 can be a strip-shaped protrusion. The first track 3013 is arranged along the length direction of the first opening edge 30111. One end of the first track 3013 is arranged close to the fourth opening edge 30114.

[0085] As Figure 5 and Figure 6As shown, the rotating member 302 has a first plane 30211, a second plane 30212, and a convex surface 30213. The first plane 30211 and the second plane 30212 are arranged oppositely. The first plane 30211 and the second plane 30212 are substantially parallel. The areas of the first plane 30211 and the second plane 30212 are substantially equal. The convex surface 30213 is located between the first plane 30211 and the second plane 30212. The area of the projection of the convex surface 30213 on the plane where the first plane 30211 is located is larger than the area of the first plane 30211. The rotating member 302 is drum-shaped. This is beneficial for the rotating member 302 to rotate within the fixed housing 301.

[0086] A second fixing mechanism 3022 is provided on the convex surface 30213. In this embodiment, the second fixing mechanism 3022 is a tenon groove. The first fixing mechanism 3012 is matched with the second fixing mechanism 3022. In this embodiment, the tenon groove is a hemispherical groove.

[0087] A second track 3023 is provided on the convex surface 30213. In this embodiment, the second track is a groove. The first track 3013 is located in the second track 3023, so that the rotating member 302 moves in the fixed housing 301 along a preset path.

[0088] The irrigation working tip 1 is located on the convex surface 30213. The irrigation working tip 1 can be arranged oppositely to the second fixing mechanism 3022. The irrigation working tip 1 is arranged to irrigate the lesion site. The lesion site can be a root canal or the root apex.

[0089] The protective sleeve 2 is sleeved on the connection part between the irrigation working tip 1 and the rotating member 302. The protective sleeve 2 shields the angle adjustment device 3. This avoids the contact between the liquid and the angle adjustment device 3 when the irrigation working tip 1 is working, causing adverse effects.

[0090] As Figure 7As shown, the rotating member 302 moves along the directions of the first track 3013 and the second track 3023. During the movement, when the second fixing mechanism 3022 on the rotating member 302 meets the first fixing mechanism 3012 on the fixed housing 301, the elastic member gradually elongates from the first compressed state, and then places the first fixing mechanism 3012 into the second fixing mechanism 3022, thereby fixing the relative positions of the fixed housing 301 and the rotating member 302. At this time, the position of the flushing working tip 1 also changes and is fixed. If the user needs to adjust the angle again, an external force is required to overcome the frictional force between the first fixing mechanism 3012 and the second fixing mechanism 3022, so that the rotating member 302 continues to move along the directions of the first track 3013 and the second track 3023. When other first fixing mechanisms 3012 meet the second fixing mechanism 3022, the relative position of the rotating member 302 and the fixed housing 301 is fixed again. At this time, the position of the flushing working tip 1 also changes and is fixed.

[0091] In this embodiment, when the second fixing mechanism 3022 cooperates with different first fixing structures 3012, the angles between the flushing working tip 1 and the first connecting rod 4 are 90°, 120°, and 150° respectively.

[0092] As Figure 2 shown, one end of the first connecting rod 4 is connected to the fixed housing 301. The minimum included angle formed between the first connecting rod 4 and the flushing working tip 1 is about 90°.

[0093] The eccentric shaft 5 is connected to the other end of the first connecting rod 4.

[0094] A driving motor (not shown) is provided in the oscillation device 7. The driving motor is connected to the eccentric shaft 5 through the second connecting rod 6. The oscillation device 7 is an oscillation rod.

[0095] The oscillation wave of the oscillation device 7 is transmitted to the eccentric shaft 5. Since its vibration axis is not at the geometric center, the eccentric shaft 5 will vibrate strongly and transmit the vibration to the angle adjustment device 3 and the flushing working tip 1.

[0096] The housing 8 is connected to the oscillation device 7.

[0097] The oscillation intensity adjustment chip module 9 is located in the housing 8. The oscillation intensity adjustment chip module 9 controls the rotation speed of the rotor in the driving motor, thereby controlling the vibration frequency of the oscillation device 7.

[0098] The control button 10 is located on the housing 8. The control button 10 includes an oscillation intensity adjustment knob and a switch knob.

[0099] When in the use state, the rechargeable battery 11 is located in the housing 8 and is connected to the oscillation intensity adjustment chip module 9.

[0100] When not in use, the rechargeable battery 11 is located in the charging position of the charging socket 12. At this time, the charging socket 12 charges the rechargeable battery 11.

[0101] When in use, the rotating component 302 is rotated to adjust the position of the flushing working tip 1. The switch knob is turned to start the flushing device, and the vibration intensity adjustment knob is turned to make the vibration device 7 at a suitable vibration frequency.

[0102] The present invention is not limited to the above-mentioned embodiments. Without departing from the essential content of the present invention, any deformation, improvement and substitution that can be conceived by those skilled in the art shall fall within the scope of the present invention.
