Description

Technical Field

[0001] The utility model relates to the technical field of oral irrigators, in particular to an oral irrigator nozzle with adjustable flow rate and an oral irrigator. Background Art

[0002] An oral irrigator is an auxiliary tool for oral cleaning. It is a tool that uses the impact of pulsed water flow to clean teeth and dental floss. There are mainly portable and desktop types. The front end of the oral irrigator is provided with a slender nozzle. A cavity is arranged inside the nozzle, and a water outlet hole is arranged at the front end of the nozzle. When water flows in the cavity and sprays out from the water outlet hole, a slender water column with a certain pressure can be generated. As long as the water outlet hole is aimed at the tooth surface or the tooth gap, the sprayed thin water column can wash the tooth surface and the gap position clean.

[0003] However, the flow rate of the thin water column sprayed by the existing oral irrigators is mostly fixed, which is related to the working intensity of the internal water pump. However, different users have different requirements for the flow rate of the sprayed water column, and there is still a large room for improvement based on the existing nozzle structure.

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

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present utility model is to provide an oral irrigator nozzle with adjustable flow rate and an oral irrigator to solve the problems mentioned in the background art.

[0006] To solve the above technical problems, the present utility model provides the following technical solutions.

[0007] The present utility model provides an oral irrigator nozzle with adjustable flow rate, including a nozzle neck, a nozzle head and a water stop block. The nozzle head is arranged at the front end of the nozzle neck. The nozzle head is inclined. A liquid cavity that communicates with each other is arranged inside the nozzle head and the nozzle neck.

[0008] A support ring is arranged on the inner wall at a lower position in the liquid cavity. A sleeve is arranged on the upper surface of the support ring. The water stop block is located directly above the center position of the support ring. The water stop block is located inside the liquid cavity. Convex blocks are arranged around the water stop block. A telescopic rod is vertically arranged on the lower surface of the convex block. The lower end of the telescopic rod is inserted into the sleeve.

[0009] A spring is vertically arranged on the inner bottom surface of the sleeve. The lower end of the spring is fixed on the inner bottom surface of the sleeve, and the upper end of the spring is fixed on the lower surface of the telescopic rod.

[0010] A central column is vertically arranged at the center of the inner bottom surface of the sleeve. The central column is located in the middle of the spring. An electromagnet is arranged on the upper surface of the central column, and a permanent magnet is arranged on the lower surface of the telescopic rod. The electromagnet is located below the permanent magnet and close to the permanent magnet.

[0011] Preferably, the outer surface of the support ring is fixed on the inner wall of the liquid cavity. There are four to six sleeves, which are evenly distributed in an equidistant and circumferential manner on the upper surface of the support ring.

[0012] Preferably, the inner diameter of the liquid cavity gradually decreases in the direction from bottom to top. The water stop block is frustum-shaped, with the large circular surface facing upward and the small circular surface facing downward. The water stop block is located in the middle of the liquid cavity.

[0013] Preferably, the number of the bumps is the same as that of the sleeves. A plurality of the bumps are evenly distributed in an equidistant and circumferential manner around the surface of the water stop block, and the bumps are aligned with the sleeves up and down.

[0014] Preferably, a guiding chute is arranged on the inner wall of the sleeve, and a guiding rib is arranged on the surface of the telescopic rod. The guiding rib is slidably installed in the guiding chute.

[0015] Preferably, the outer surface of the spring abuts against the inner wall of the sleeve.

[0016] Preferably, the inner surface of the spring abuts against the outer surface of the central column.

[0017] On the other hand, the present utility model also provides a dental irrigator, including the dental irrigator nozzle described above.

[0018] Compared with the prior art, the present utility model has the following beneficial effects:

[0019] When the electromagnet is energized, an upward thrust can be generated on the permanent magnet on the lower surface of the telescopic rod, so that the telescopic rod, the bumps and the water stop block can move upward as a whole. Since the water stop block is frustum-shaped and the liquid cavity gradually decreases from bottom to top, the distance between the surface of the water stop block and the inner wall of the liquid cavity gradually decreases;

[0020] That is, when the water flows upward in the liquid cavity, due to the decrease in the distance between the water stop block and the inner wall of the liquid cavity, the flow velocity and flow rate of the water passing through are both reduced. When the thrust generated by the electromagnet is small, under the downward pulling force of the spring, the water stop block can move downward, and the distance between the water stop block and the inner wall of the liquid cavity becomes larger, so that the water flow and flow rate can increase;

[0021] That is, under the action of the magnetic thrust of the electromagnet and the reaction force of the spring, the water stop block can move up and down, so that the distance between the water stop block and the inner wall of the liquid cavity can be adjusted, and the water flow and flow rate passing through can also be adjusted accordingly. The water flow rate and flow rate at the outlet of the liquid cavity can be adjusted according to the user's habits. Brief Description of the Drawings

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a 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 orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0029] As Figures 1-4 shown, a water flosser nozzle with adjustable flow rate includes a nozzle neck 1, a nozzle 2 and a water stop block 3. The nozzle 2 is arranged at the front end of the nozzle neck 1. The nozzle 2 is inclined. A liquid cavity 11 that communicates with each other is arranged inside the nozzle 2 and the nozzle neck 1, that is, water flow can flow inside the liquid cavity 11;

[0030] There is a support ring 12 provided on the inner wall at a lower position inside the liquid chamber 11. A sleeve 13 is provided on the upper surface of the support ring 12. The water stop block 3 is located directly above the center position of the support ring 12. The water stop block 3 is located inside the liquid chamber 11. There are convex blocks 31 provided around the water stop block 3. A telescopic rod 14 is vertically provided on the lower surface of the convex block 31. The lower end of the telescopic rod 14 is inserted into the sleeve 13; and the telescopic rod 14 can move up and down inside the sleeve 13.

[0031] There is a spring 131 vertically provided on the inner bottom surface of the sleeve 13. The lower end of the spring 131 is fixed to the inner bottom surface of the sleeve 13, and the upper end of the spring 131 is fixed to the lower surface of the telescopic rod 14.

[0032] There is a central column 132 vertically provided at the center of the inner bottom surface of the sleeve 13. The central column 13 is located in the middle of the spring 131. An electromagnet 133 is provided on the upper surface of the central column 13. A permanent magnet is provided on the lower surface of the telescopic rod 14. The electromagnet 133 is located below the permanent magnet and close to the permanent magnet; when the electromagnet is energized, it can push the permanent magnet 133 and the telescopic rod 14 to generate an upward thrust, causing the water stop block 3 to move upward. When the magnetic thrust of the electromagnet becomes smaller, under the reaction force of the spring 131, the water stop block 3 can move downward; that is, through the cooperation of the electromagnet 133 and the spring 131, the up and down movement of the water stop block 3 can be realized.

[0033] The outer surface of the support ring 12 is fixed to the inner wall of the liquid chamber 11. There are four to six sleeves 13, which are evenly distributed in an equidistant and circumferential manner on the upper surface of the support ring 12. In this way, the multiple sleeves 13 have a better supporting force for the telescopic rod 14 and the water stop block 3.

[0034] The inner diameter of the liquid chamber 11 gradually becomes smaller in the direction from bottom to top. The water stop block 3 is frustum-shaped, with the large circular surface of the water stop block 3 facing upward and the small circular surface facing downward. The water stop block 3 is located at the middle position of the liquid chamber 11. That is, as the water stop block 3 moves up and down, the distance between the water stop block 3 and the inner wall of the liquid chamber 11 changes.

[0035] The number of the convex blocks 31 is the same as the number of the sleeves 13. The multiple convex blocks 31 are evenly distributed in an equidistant and circumferential manner around the surface of the water stop block 3, and the convex blocks 31 are vertically aligned with the sleeves 13.

[0036] There are guiding chutes provided on the inner wall of the sleeve 13, and guiding protrusions are provided on the surface of the telescopic rod 14. The guiding protrusions are slidably installed in the guiding chutes. In this way, when the telescopic rod 14 slides up and down, it is more stable.

[0037] The outer surface of the spring 131 abuts against the inner wall of the sleeve 13.

[0038] The inner surface of the spring 131 abuts against the outer surface of the central column 132; that is, the left and right positions of the spring 131 can be fixed, and the spring 131 can only move up and down and will not sway left and right.

[0039] On the other hand, the present utility model also provides a dental irrigator, including the dental irrigator nozzle described above.

[0040] In summary: When the electromagnet 133 is energized, an upward thrust can be generated on the permanent magnet on the lower surface of the telescopic rod 14, so that the telescopic rod 14, the convex block 31 and the water stop block 3 can move upward as a whole. Since the water stop block 3 is frustum-shaped and the liquid cavity 11 gradually becomes smaller from bottom to top, the distance between the surface of the water stop block 3 and the inner wall of the liquid cavity 11 gradually becomes smaller;

[0041] That is, when the water flow flows upward in the liquid cavity 11, due to the decrease in the distance between the water stop block 3 and the inner wall of the liquid cavity 11, the flow rate and the flow volume of the water flow passing through are both reduced. When the thrust generated by the electromagnet 133 is small, under the downward pulling force of the spring 131, the water stop block 3 can move downward, and the distance between the water stop block 3 and the inner wall of the liquid cavity 11 becomes larger, so that the water flow and the flow volume can increase;

[0042] That is, under the action of the magnetic thrust of the electromagnet 133 and the reverse pulling force of the spring 131, the water stop block 3 can move up and down, so that the distance between the water stop block 3 and the inner wall of the liquid cavity 11 can be adjusted, and the water flow and the flow volume passing through can also be adjusted accordingly. The outflow speed and the flow volume of the water flow at the outlet of the liquid cavity 11 can be adjusted according to the user's habit.

[0043] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
