Description

Technical Field

[0001] The present invention belongs to the technical field of oral cleaning, and in particular relates to a water-powered telescopic vibration nozzle of a water flosser. Background Art

[0002] An oral irrigator is an auxiliary tool for cleaning the oral cavity. It uses pulsed water flow to clean teeth and the spaces between teeth. It is mainly available in portable and desktop models. The high-speed water flow of the oral irrigator has its unique cleaning and health care functions and is easy to use. In the past, the oral irrigator has been used as an auxiliary supplement to the toothbrush. It is designed with a single water column and limited water volume to flush the spaces between teeth and the gingival sulcus, which are difficult to clean with a toothbrush.

[0003] The current water irrigators are only auxiliary cleaning tools. Although there are many types of nozzles, the current water irrigators cannot replace the cleaning effect of traditional toothbrushes. Secondly, the electric toothbrushes on the market cannot achieve watering and brushing at the same time, so the cleaning effect of the water irrigator cannot be guaranteed, resulting in the overall practicality of the water irrigator being low. For this purpose, a water-powered telescopic vibrating nozzle for the water irrigator is provided. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that current water flossers cannot achieve the two functions of water flossing and brushing teeth at the same time, and to propose a water-powered telescopic vibrating nozzle for water flossers.

[0005] In order to achieve the above object, the present invention adopts the following technical solution: a water-powered telescopic vibration nozzle of a water irrigator, comprising: a water stop switch, wherein the upper surface and the lower surface of the water stop switch are both provided with notches;

[0006] A brush rod, wherein a through hole is provided inside the brush rod;

[0007] Among them, 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 perform telescopic movement.

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

[0009] A groove is provided on the upper surface of the connecting rod, 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 be rotated inside the water stop switch to turn on and off the water.

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

[0011] One end of the brush rod passes through the notch on the upper surface of the water stop switch and penetrates the inside of the spring. One 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 seepage.

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

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

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

[0015] The brush head is provided with a perforation inside, and the perforation is aligned with the inside of the through hole of the brush rod.

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

[0017] A pipe hole is provided inside the connecting rod, and the pipe hole and the water stopper 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 after the overall assembly. 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 the present invention are:

[0021] In the present invention, a spring and a water stop plug are provided, and a spring is installed in the water stop switch. When the pump body piston absorbs water, the spring applies a force to the water in the water channel. The piston will first absorb the water in the water channel, and use the water to transmit the force to the brush head, thereby forming a reciprocating cycle of pumping out and sucking the same volume of water to achieve expansion and contraction. The nozzle vibrates with high frequency expansion and contraction to brush the teeth. For the residue inside the teeth, the deep part of the teeth can be cleaned by turning on the nozzle switch, realizing the synchronous operation of brushing and irrigating, improving the efficiency and cleaning power of brushing, and thus improving the practicality of the toothbrush irrigator nozzle. In terms of toothbrushes, the irrigator has its own water tank, which is more convenient for cleaning the ointment foam generated during brushing. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] When implementing it specifically, Figure 1-Figure 4 As shown, the present invention provides a technical solution: a water-dynamic telescopic vibrating nozzle for a water flosser, comprising a water stop switch 1, the upper and lower surfaces of which are provided with notches; a brush rod 2, the interior of which is provided with a through hole; wherein, a spring 7 is fixedly mounted on the inner wall of the top surface of the water stop switch 1, and a connecting rod 4 is fixedly mounted on one end of the spring 7, the upper surface of the connecting rod 4 is provided with a groove, a sealing ring 6 is fixedly mounted on the inner wall of the bottom surface of the groove, and a water stop plug 5 is rotatably mounted on the inner wall of the bottom surface of the groove, one end of the brush rod 2 passes through the interior of the spring 7 through the notch on the upper surface of the water stop switch 1, and 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, and a brush head 3 is fixedly mounted on one end of the brush rod 2, and bristles are fixedly mounted 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 water on and off. Then assemble the water stop switch 1, spring 7, sealing ring 6 and the connecting rod 4 together. After the assembly is completed, 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 turning the water on and off;

[0031] like Figure 2-Figure 4 As shown, the brush head 3 is provided with a perforation inside, which is aligned with the through hole inside the brush rod 2. The connecting rod 4 is provided with a pipe hole inside, and the pipe 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 overall assembly, it becomes a telescopic vibrating toothbrush nozzle.

[0032] When the water stop plug 5 is in the closed state, the brush rod 2 and the brush head 3 are not connected. When the piston of the water flosser pump body 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, and 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, thereby realizing the extension and contraction of the brush rod 2 and the brush head 3; when the water stop plug 5 is in the closed state, the brush rod 2 and the brush head 3 are not connected. Then, turn the water stop switch 1 and rotate the brush head 3. At this time, the brush rod 2 and the water stop plug 5 are in the connected state, and then high-pressure water is ejected from the through holes and perforations of the brush rod 2 and the brush head 3, realizing 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 water on and off. Then assemble the water stop switch 1, spring 7, sealing ring 6 and connecting rod 4 together. After the assembly is completed, 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 turning the water on and off.

[0034] When the water stop plug 5 is in the closed state, the brush rod 2 and the brush head 3 are not connected to each other. 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, thereby realizing the extension and retraction of the brush rod 2 and the brush head 3.

[0035] When the water stop plug 5 is in the closed state, the brush rod 2 and the brush head 3 are not connected. Then, the water stop switch 1 is turned to rotate the brush head 3. At this time, the brush rod 2 and the water stop plug 5 are in the conductive state. Then, high-pressure water is ejected from the through-holes and perforations of the brush rod 2 and the brush head 3 to realize the flushing principle.

[0036] There is a high-pressure water pump in the oral irrigator. The piston in the water pump expands and contracts back and forth at a high frequency to pump out high-pressure water through the catheter. Based on this basic principle, liquid is an incompressible medium, so the volume of water sucked in and pumped out by the piston remains constant in the entire water channel. A spring 7 is installed in the water stop switch 1. When the pump piston absorbs water, the spring 7 applies a force to the water in the water channel. The piston will preferentially absorb the water in the water channel and use the water to transmit the force to the brush head 3, thereby forming a reciprocating cycle of pumping out and sucking the same volume of water to achieve expansion and contraction. The high-frequency expansion and contraction will produce a constant vibration frequency, and the frequency of the piston movement is the frequency of vibration of the brush head 3.

[0037] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
