Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a precise metering oral rinsing solution dispenser. Background Technology

[0002] Oral irrigation, as a crucial part of modern oral care, plays a key role in maintaining oral health. Currently, syringe-type irrigators are the most widely used auxiliary tools in clinical practice. However, existing oral irrigators generally use a manual control mode to adjust the intensity and duration of the irrigating solution. While this design offers the advantage of ease of operation, it makes it difficult to achieve precise control of the irrigating solution volume. In actual use, users often need to adjust the irrigating solution volume based on subjective feeling. This not only leads to significant fluctuations in the amount of irrigating solution drawn each time, but also makes it difficult to maintain a stable and accurate final volume of irrigating solution, affecting the reliability and consistency of the irrigating effect. Utility Model Content

[0003] This invention provides a precise oral rinsing solution dispenser. Through optimized structural design, it achieves accurate dispensing of oral rinsing solution while improving ease of operation, thus solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A precise metering oral irrigator includes an injection bottle body with a handheld plate extending from it. An auxiliary metering sleeve is located on the handheld plate.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides a precise metering oral rinsing solution dispenser, which includes an injection bottle body 1. A handheld grip plate 2 extends from the injection bottle body 1 for easy gripping and operation. Its ergonomic design effectively reduces operator fatigue. An auxiliary metering sleeve 3 is located on the handheld grip plate 2. A piston rod 4 is movably inserted into the injection bottle body 1, and the rod portion of the piston rod 4 is also movably positioned inside the auxiliary metering sleeve 3. The up-and-down movement of the piston rod 4 enables the intake and discharge of oral rinsing solution. A limiting ring 5 is provided on the outside of the auxiliary metering sleeve 3, and a limiting block 6 is provided on the limiting ring 5. The limiting block 6 extends into the auxiliary metering sleeve 3, and the limiting ring 5 synchronously adjusts the position of the limiting block 6 inside the auxiliary metering sleeve 3 to achieve a limiting effect, thus restricting the movement stroke of the piston rod 4. The limiting ring 5 can slide along the side wall of the auxiliary metering sleeve 3. Therefore, a bidirectional ratchet 7 is provided in its side wall to control the sliding position of the limiting ring 5, so that the movement stroke of the piston column 4 is limited and controlled, thereby achieving accurate metering of oral rinsing fluid intake and ensuring accurate metering of oral rinsing fluid discharge.

[0022] Specifically, firstly, as Figure 3 and Figure 4 As shown, a rotating gear 8 is provided on the limiting ring 5. There are two rotating gears 8 on the limiting ring 5 to ensure the reliability and stability of operation. A bidirectional ratchet 7 is provided on the rotating gear 8. Therefore, by adjusting the different rotation directions of the bidirectional ratchet 7, the rotation direction of the rotating gear 8 can also be synchronized. Since two racks 9 are correspondingly provided in the side wall of the auxiliary metering sleeve 3 to mesh with the rotating gear 8, there are actually four rotating gears 8 on the limiting ring 5, that is, two rotating gears 8 meshing with the corresponding racks 9 at each end of the limiting ring 5. During operation, by pulling the limiting ring 5, the rotating gear 8 rolls on the racks 9. Since the rotating gear 8 is rotatably mounted on the limiting ring 5, its rotation effect can be achieved through the provided rotating shaft. Therefore, the limiting ring 5 can slide up and down on the auxiliary metering sleeve 3.

[0023] The structure of the two-way ratchet 7 is as follows Figure 4As shown, a first limiting stop 10 is rotatably mounted on one end of the bidirectional ratchet 7, and the first limiting stop 10 is connected by a spring 12. A second limiting stop 11 is rotatably mounted on the other end of the bidirectional ratchet 7, and the second limiting stop 11 is connected by a spring 12. An internal adjusting lever 13 is rotatably mounted between the first limiting stop 10 and the second limiting stop 11. By rotating the internal adjusting lever 13 to adjust the rotation direction, the first limiting stop 10 and the second limiting stop 11 are pressed against each other, thereby achieving the rotation effect of the bidirectional ratchet 7. Since the working principle of the bidirectional ratchet 7 has already been applied in the prior art, it will not be described in detail here.

[0024] Furthermore, an external adjustment lever 14 is provided on the outer side wall of the limiting ring 5. The external adjustment lever 14 and the internal adjustment lever 13 are rotatably connected to each other and can achieve synchronous connection through the internal connecting rod. The shape of the external adjustment lever 14 can be similar to that of the internal adjustment lever 13. In use, by moving the external adjustment lever 14, the internal adjustment lever 13 can be made to move synchronously, thereby changing the rotation direction of the bidirectional ratchet 7.

[0025] Furthermore, a push-pull press plate 15 is provided at the top of the piston column 4 for easy user operation. Extension baffles 16 are respectively provided on the side walls at both ends of the piston column 4. The extension baffles 16 are located inside the auxiliary metering sleeve 3 and between the handheld clamping plate 2 and the limiting ring 5. The extension baffles 16 are used to restrict the movement space of the piston column 4. During use, the movement space of the piston column 4 can be changed by adjusting the distance between the limiting ring 5 and the handheld clamping plate 2, thereby ensuring accurate metering of the oral irrigation fluid aspirated by the piston column 4.

[0026] Multiple travel scales 17 are provided on the outer side wall of the auxiliary measuring sleeve 3. The number of rotations of the rotating gear 8 is matched with the distance between each travel scale 17. The travel of the limit ring 5 can be adaptively changed according to the actual use. For example, by setting the distance of one tooth rotation of the rotating gear 8 on the rack 9, it is exactly the distance of one scale slide of the limit ring 5 on the travel scale 17. The distance between each travel scale 17 can be set to 1 mm, 2 mm or 3 mm, so as to achieve the precise operation of the limit ring 5 and thus achieve the precise measurement effect.

[0027] Furthermore, the outer sidewall of the injection bottle 1 is provided with a volume scale 18 to visually display the remaining amount of oral rinsing solution, making it easy for the user to observe. One end of the injection bottle 1 is provided with a dispensing needle 19, which has an arc-shaped structure, allowing for precise delivery of oral rinsing solution to the target area in the oral cavity during use, improving the smoothness of operation.

[0028] In summary, this utility model provides a precise oral rinsing solution dispenser. The user first controls the movement of the piston rod 4 by pushing and pulling the pressure plate 15, drawing the oral rinsing solution into the injection bottle 1. The position of the limiting ring 5 is adjusted by the external adjustment lever 14. Combined with the cooperation of the limiting ring 5, the rotating gear 8, and the bidirectional ratchet 7, precise dispensing of the oral rinsing solution is achieved, meeting the needs of different scenarios.
