Method used

The advantage of the present invention is: by setting pressurization chamber on handle, the diameter of pressurization chamber cross-section is greater than the nozzle diameter of sprinkler cross-section, so water force increases when coming out from nozzle, thereby need not utilize motor in addition The driving water is sprayed from the nozzle, which saves cost and facilitates popularization.
[0022] Specifically, the diameter of the cross-section of the booster chamber 103 is 8.0 mm to 12.0 mm, while the diameter of the cross-section of the nozzle 112 is 1.0 mm to 0.5 mm. More specifically, the diameter of the cross-section of the pressurization chamber 103 may be 10.0 mm, and the diameter of the cross-section of the nozzle 112 may be 0.7 mm. When the hose 2 is connected to the water source, the water flows through the hose 2 and the connecting device 12, and enters the pressurized chamber 103 from the water i...

Example Embodiment

[0020] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0021] figure 1 It shows a schematic structural diagram of a water-driven tooth flusher in an embodiment according to the present invention. Reference figure 1 , The water-driven tooth flusher 1 includes: a handle 10 and a nozzle 11. The handle 10 has a water inlet 101, a water outlet 102, and a pressurizing cavity 103, and the water inlet 101 can be connected with a hose 2 to access a water source. It should be particularly noted here that the water source can be a household tap water source, and the location of the water source should be higher than that of the handle 10. In order to facilitate the connection of the hose 2 to the handle 10, threads may be provided on the outer surface of the handle 10. The pressurizing cavity 103 connects the water inlet 101 with the water outlet 102. The nozzle 11 is connected to the water outlet 102. The nozzle 11 has a passage 111 and a nozzle 112. The nozzle 112 is connected to the passage 111. In addition, the passage 111 communicates with the boosting chamber 103, and the cross-sectional diameter of the nozzle 112 is smaller than that of the boosting chamber 103. The diameter of the cross section.
[0022] Specifically, the diameter of the cross section of the pressurizing chamber 103 is 8.0 mm to 12.0 mm, and the diameter of the cross section of the nozzle 112 is 1.0 mm to 0.5 mm. More specifically, the diameter of the cross section of the pressurizing chamber 103 may be 10.0 mm, and the diameter of the cross section of the nozzle 112 is 0.7 mm. When the hose 2 is connected to the water source, the water flows through the hose 2 and the connecting device 12, from the water inlet 101 of the handle 10 into the pressurizing chamber 103, and then the water in the pressurizing chamber 103 passes through the water outlet 102 of the handle 10. It flows into the channel 111 of the nozzle 11, and finally the water flows out from the nozzle 112. Because the diameter of the cross-section of the nozzle 112 is smaller than the diameter of the cross-section of the boosting chamber 103, when water flows from the boosting chamber 103 into the nozzle 11 and out of the nozzle 112, the force will increase and the water flow will be sprayed from the nozzle 112. Then, you can use this jet of water to clean your teeth, which is simple and convenient. In addition, in this embodiment, the handle 10 and the spray head 11 are integrally formed, and the two materials may be plastic materials. The spray head 11 can be arranged in an L shape, which can better align the teeth.
[0023] figure 2 It shows an exploded view of the structure of the hydraulic tooth flusher in another embodiment according to the present invention. Reference figure 2 In order to better realize the connection between the handle 10 and the hose 2, in this embodiment, the water-driven dental flusher 3 further includes a connecting device 12 that connects the hose 2 to the handle 10. More specifically, one end of the connecting device 12 has a cylindrical body 121, and the other end is provided with an opening 122, and the hose 2 can be sleeved on the cylindrical body 121 to realize the connection of the connecting device 12 and the hose 2. A protrusion 104 is provided on the water inlet 101 of the handle 10 to match the opening 122 of the connecting device 12, and the protrusion 104 is snapped into the opening 122 of the connecting device 12. Therefore, the connecting device 12 is connected to the handle 10, thereby The connection between the hose 2 and the handle 10 is realized. In addition, a sealing ring 13 can be provided, and an annular groove 123 is provided on the water inlet 101 of the handle 10. The annular groove 123 is matched with the sealing ring 13 so that the sealing ring 13 is locked in the annular groove 123, To ensure the tightness of the connection between the hose 2 and the connecting device 12. The sealing ring 13 may be made of rubber material.
[0024] The advantage of the present invention is that by providing a booster cavity on the handle, the cross-sectional diameter of the booster cavity is larger than the diameter of the nozzle of the nozzle cross-section, so when the water comes out of the nozzle, the force increases, so there is no need to use a motor to drive the water from The nozzle sprays, which saves cost and facilitates promotion.
[0025] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the industry should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the description only illustrate the principles of the present invention. The present invention will have various aspects without departing from the spirit and scope of the present invention. Various changes and improvements, these changes and improvements fall within the scope of the claimed invention. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
