Description

Technical Field

[0001] This utility model belongs to the field of oral hygiene technology, and in particular relates to a water-powered telescopic vibration nozzle for a water flosser. Background Technology

[0002] A water flosser is an auxiliary tool for cleaning the oral cavity. It uses pulsed water jets to clean teeth and between teeth. It is mainly available in portable and countertop models. The high-speed water jet of a water flosser has unique cleaning and health care functions and is easy to use. Water flossers were originally used as an auxiliary tool to toothbrushes. They are designed with a single water jet and limited water volume to clean areas that are difficult to clean with a toothbrush, such as between teeth and gum line.

[0003] Current water flossers are only auxiliary cleaning tools. Although there are many types of nozzles, current water flossers cannot replace the cleaning function of traditional toothbrushes. Furthermore, electric toothbrushes on the market cannot simultaneously irrigate and brush teeth, thus failing to guarantee the cleaning effect of water flossers. As a result, the overall practicality of water flossers is low. To address this, a water-powered telescopic vibrating nozzle for water flossers has been developed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that current oral irrigators cannot simultaneously perform both oral irrigation and brushing functions, and to propose an oral irrigator with a water-driven telescopic vibration nozzle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a water-powered telescopic vibration nozzle for a dental irrigator, comprising: a water-stop switch, wherein the upper and lower surfaces of the water-stop switch are provided with slots;

[0006] The brush rod has a through hole inside.

[0007] A spring is fixedly installed on the inner wall of the top surface of the water-stop switch, and a connecting rod is fixedly installed on one end of the spring. The spring is installed inside the water-stop switch and acts on the brush rod and the water-stop plug to make telescopic movements.

[0008] As a further description of the above technical solution:

[0009] The upper surface of the connecting rod is provided with a groove, a sealing ring is fixedly installed on the inner wall of the bottom surface of the groove, and a water stop plug is rotatably installed on the inner wall of the bottom surface of the groove. The water stop plug can rotate inside the water stop switch to turn the water on and off.

[0010] As a further description of the above technical solution:

[0011] One end of the brush rod passes through the groove on the upper surface of the water-stop switch and enters the interior of the spring. The other end of the brush rod extends into the groove of the connecting rod. The sealing ring is located between the brush rod and the water-stop plug. The sealing ring is used to seal between the brush rod and the water-stop plug to prevent water leakage.

[0012] As a further description of the above technical solution:

[0013] A brush head is fixedly installed at one end of the brush rod, and bristles are fixedly installed on the side wall of the brush head.

[0014] As a further description of the above technical solution:

[0015] The brush head has a perforation inside, which is aligned with the through hole in the brush handle.

[0016] As a further description of the above technical solution:

[0017] The connecting rod has a pipe hole inside, and the pipe hole and the water stop plug of the connecting rod are aligned with the through hole of the brush rod.

[0018] As a further description of the above technical solution:

[0019] The water stop switch, spring, sealing ring and connecting rod are assembled together to form a telescopic vibrating toothbrush nozzle. The rotation of the water stop switch can drive the brush rod to rotate to turn the water on and off.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] In this invention, a spring and a water stop plug are incorporated. The water stop plug contains a spring. When the pump piston draws in water, the spring applies a force to the water in the water path. The piston preferentially draws in the water in the water path, and the force is transmitted to the brush head, thus forming a reciprocating cycle of pumping out and drawing in the same volume of water to achieve expansion and contraction. The nozzle vibrates at high frequency to brush the teeth. For residue inside the gaps between teeth, simply opening the nozzle switch cleans the deep gaps. This achieves simultaneous brushing and flossing, improving brushing efficiency and cleaning power, thereby enhancing the practicality of the toothbrush and flosser nozzle. In terms of the toothbrush, the built-in water tank of the flosser makes it easier to clean the toothpaste foam produced during brushing. Attached Figure Description

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] In specific implementation, such as Figures 1-4 As shown, this utility model provides a technical solution: a water-powered telescopic vibrating nozzle for a dental irrigator, including a water-stop switch 1, with grooves on both the upper and lower surfaces of the water-stop switch 1; a brush rod 2, with a through hole inside the brush rod 2; wherein, a spring 7 is fixedly installed on the inner wall of the top surface of the water-stop switch 1, a connecting rod 4 is fixedly installed on one end of the spring 7, a groove is provided on the upper surface of the connecting rod 4, a sealing ring 6 is fixedly installed on the inner wall of the bottom surface of the groove, a water-stop plug 5 is rotatably installed on the inner wall of the bottom surface of the groove, one end of the brush rod 2 passes through the groove on the upper surface of the water-stop switch 1 and enters the interior of the spring 7, one end of the brush rod 2 extends into the groove of the connecting rod 4, the sealing ring 6 is located between the brush rod 2 and the water-stop plug 5, a brush head 3 is fixedly installed on one end of the brush rod 2, and bristles are fixedly installed on the side wall of the brush head 3.

[0030] Assemble the connecting rod 4 and the water stop plug 5 together. The water stop plug 5 can rotate inside the water stop switch 1 to control the opening and closing of the water. Then assemble the water stop switch 1, spring 7, sealing ring 6 and connecting rod 4 together. After assembly, rotate the water stop switch 1. At this time, the water stop switch 1 will drive the brush rod 2 to rotate, thereby realizing the function of opening and closing the water.

[0031] like Figures 2-4 As shown, the brush head 3 has a perforation inside, which is aligned with the through hole of the brush rod 2. The connecting rod 4 has a tube hole inside, and the tube hole and water stop plug 5 of the connecting rod 4 are aligned with the through hole of the brush rod 2. The water stop switch 1, spring 7, sealing ring 6 and connecting rod 4 are assembled together. After the whole assembly, it is a telescopic vibrating toothbrush nozzle.

[0032] When the stop plug 5 is closed, the brush rod 2 and brush head 3 are not internally connected. When the piston of the water flosser pump pushes out high-pressure water, the stop plug 5 and brush rod 2 move from the first position to the second position inside the stop switch 1. Then, under the elastic force of the spring 7, the stop plug 5 and brush rod 2 move from the second position to the first position inside the stop switch 1 again, forming a reciprocating motion to realize the extension and retraction of the brush rod 2 and brush head 3. When the stop plug 5 is closed, the brush rod 2 and brush head 3 are not internally connected. Then, the stop switch 1 is rotated to rotate the brush head 3. At this time, the brush rod 2 and stop plug 5 are connected. Then, high-pressure water flows out from the through holes and perforations of the brush rod 2 and brush head 3 to realize the flushing principle.

[0033] Working principle: Assemble the connecting rod 4 and the water stop plug 5 together. The water stop plug 5 can rotate inside the water stop switch 1 to control the opening and closing of the water. Then assemble the water stop switch 1, spring 7, sealing ring 6 and connecting rod 4 together. After assembly, rotate the water stop switch 1. At this time, the water stop switch 1 will drive the brush rod 2 to rotate, thereby realizing the function of opening and closing the water.

[0034] When the water stop plug 5 is in the closed state, the brush rod 2 and the brush head 3 are not internally connected. When the piston of the water flosser pump pushes out high-pressure water, the water stop plug 5 and the brush rod 2 move from the first position to the second position inside the water stop switch 1. Then, under the elastic force of the spring 7, the water stop plug 5 and the brush rod 2 move from the second position to the first position inside the water stop switch 1 again, forming a reciprocating motion to realize the extension and retraction of the brush rod 2 and the brush head 3.

[0035] When the water stop plug 5 is closed, the brush rod 2 and the brush head 3 are not connected internally. Then, turn the water stop switch 1 to rotate the brush head 3. At this time, the brush rod 2 and the water stop plug 5 are connected. Then, high-pressure water flows out from the through holes and perforations of the brush rod 2 and the brush head 3 to achieve the flushing principle.

[0036] The water flosser contains a high-pressure water pump. The piston inside the pump reciprocates at high frequency, pumping out high-pressure water through a conduit. Based on the principle that liquid is an incompressible medium, the volume of water drawn in and pumped out by the piston remains constant throughout the water circuit. The stop switch 1 contains a spring 7. When the pump piston draws in water, the spring 7 applies a force to the water in the water circuit. The piston will preferentially draw in water from the water circuit and use the water to transfer the force to the brush head 3, thus forming a reciprocating cycle of pumping out and drawing in the same volume of water to achieve expansion and contraction. The high-frequency expansion and contraction will generate a constant vibration frequency, and the frequency of the piston movement is the vibration frequency of the brush head 3.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
