[0002] An oral irrigator is an auxiliary tool for cleaning the oral cavity. It uses a pulsed water flow to clean teeth and the gaps between teeth. It mainly includes portable and desktop types. An oral irrigator is a structure used for oral care. The oral irrigator uses a certain pressure to spray a column of cleaning water from the nozzle of the oral irrigator to clean the user's mouth. The front end of the existing oral irrigator nozzle is mostly curved at a specific angle, which conforms to the ergonomic design. When the nozzle enters the oral cavity, the front end of the nozzle is curved at a certain angle, so the front end of the nozzle can just face the gaps between teeth and the surface of the teeth.

[0003] However, the bending angle of the front end of the existing oral irrigator nozzle is mostly specific and cannot be flexibly adjusted, and there is still much room for improvement.

[0004] In view of the above situation, the present utility model is proposed. Utility Model Content

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0029] like Figure 1-3 As shown, an angle-adjustable oral irrigator nozzle includes a nozzle rod 1, an adapter block 2, and a nozzle head 3. The adapter block 2 is threadedly connected to the upper end of the nozzle rod 1, and the nozzle head 3 is installed at the end of the adapter block 2 away from the nozzle rod 1. The adapter block 2 is curved, so that the nozzle rod 1 and the nozzle head 3 are in a bent state.

[0030] A first liquid chamber 12 is provided inside the nozzle rod 1, and a second liquid chamber 32 is provided inside the nozzle head 3. The first liquid chamber 12 penetrates the nozzle rod 1 along the length direction of the nozzle rod 1, and the second liquid chamber 32 penetrates the nozzle head 3 along the length direction of the nozzle head 3. Water can flow freely in the first liquid chamber 12 and the second liquid chamber 32.

[0031] The adapter block 2 is provided with a protective layer 23, an isolation layer 24 and an inner tube 25 in sequence from the outer layer to the inner layer. The lower end of the cavity of the inner tube 25 is connected to the first liquid cavity 12, and the upper end of the cavity of the inner tube 25 is connected to the second liquid cavity 32, that is, water can flow inside the adapter block 2;

[0032] The adapter block 2 is a flexible metal tube or a corrugated tube. The outer diameter of the upper end of the connecting block 2 is consistent with the outer diameter of the lower end of the nozzle head 3, and the outer diameter of the lower end of the connecting block 2 is consistent with the outer diameter of the upper end of the nozzle rod 1. That is, when the connecting block 2 is connected between the nozzle rod 1 and the nozzle head 3, the outer surfaces of the nozzle rod 1, the connecting block 2 and the nozzle head 3 are all flat.

[0033] A first convex ring 21 is provided at the lower end of the connecting block 2, a second groove 22 is provided at the upper end of the connecting block 2, a second convex ring 31 is provided at the lower end of the nozzle head 3, and a first groove 11 is provided at the upper end of the nozzle rod 1. The first convex ring 21 is threadedly connected in the first groove 11, and the second convex ring 31 is threadedly connected in the second groove 22; in this way, a detachable connection is achieved among the nozzle rod 1, the adapter block 2 and the nozzle head 3.

[0034] The height of the first protruding ring 21 is consistent with the depth of the first groove 11 , and the height of the second protruding ring 31 is consistent with the depth of the second groove 22 .

[0035] The second groove 22 is provided on the upper surface of the isolation layer 24 , and the first protruding ring 21 is provided on the lower surface of the isolation layer 24 .

[0036] The inner diameter of the inner tube body 25 gradually decreases from bottom to top. The inner diameter of the lower end of the inner tube body 25 is consistent with the inner diameter of the upper end of the first liquid cavity 12, and the inner diameter of the upper end of the inner tube body 25 is consistent with the inner diameter of the lower end of the second liquid cavity 32. That is, when water flows in the first liquid cavity 12, the inner tube body 25 and the second liquid cavity 32, the speed of the water flow can be gradually accelerated due to the gradual decrease in the inner diameter.

[0037] The surface of the adapter block 2 is evenly spaced with multiple anti-slip ridges along the height direction of the adapter block 2, which makes it easy to pinch or hold the adapter block 2 to achieve disassembly and assembly between the nozzle rod 1, the adapter block 2 and the nozzle head 3.

[0038] The maximum angle between the plane where the lower surface of the adapter block 2 is located and the plane where the upper surface is located is 70°, and the minimum angle is 0°. At this time, the lower surface and the upper surface of the adapter block 2 are parallel, and the nozzle rod 1 and the nozzle head 3 are vertical.

[0039] On the other hand, the present invention also provides a water flosser, comprising the water flosser nozzle.

[0040] In summary, the adapter block 2 connects the upper end of the nozzle rod 1 and the lower end of the nozzle head 3, and the first liquid chamber 12, the cavity of the inner tube 25, and the second liquid chamber 32 are interconnected. In this way, water can flow from the first liquid chamber 12 into the inner tube 25, then into the second liquid chamber 32, and finally be ejected from the front end of the nozzle head 3.

[0041] The first protruding ring 21 is threadedly connected to the first groove 11, and the second protruding ring 31 is threadedly connected to the second groove 22, so that the nozzle rod 1, the adapter block 2 and the nozzle head 3 can be directly disassembled;

[0042] The protective layer 23, the isolation layer 24, and the inner tube 25 are all bendable, so that the bending angle of the entire adapter block 2 itself can be adjusted, that is, the angle between the nozzle rod 1 and the nozzle head 3 can be adjusted. When used by different people, the adapter block 2 and the nozzle head 3 can be bent to the desired position in advance according to the position of the teeth and usage habits. In this way, when the nozzle rod 1 enters the oral cavity, the water flow can be sprayed out through the nozzle head 3;

[0043] By bending the adapter block 2 itself, the bending angle of the front end of the oral irrigator nozzle can be adjusted, making it more flexible and easy to use and suitable for a wider range of people with different habits.

[0044] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
