Description

Technical Field

[0001] The utility model relates to a water flosser, in particular to a table type water flosser with double spray heads and handles. Background Art

[0002] Water flossers are an auxiliary tool for cleaning the oral cavity. They use pulsed water flow to clean teeth and gaps between teeth, and can effectively protect periodontal and oral health. As people put forward higher requirements for improving the quality of life and paying attention to personal oral health, water flossers have been rapidly popularized and applied. According to different application scenarios, water flossers mainly include pull-out type, handheld portable and desktop water flossers.

[0003] Desktop water flossers are commonly known as "home professional water flossers" in Europe and the United States. They are suitable for users who have higher requirements for oral health after using pull-out water flossers or handheld portable water flossers for the first time. As a professional version of desktop water flossers, compared with pull-out water flossers or handheld portable water flossers, they must have a better user experience, such as product functionality, convenience, hygiene, etc.

[0004] As we all know, water flossers are equipped with nozzle accessories with different functions to adapt to different application scenarios. As a professional version of desktop water flossers, all water flossers on the market are single-handle configurations. Because it is a single handle, users need to replace the nozzle according to different needs, which brings great inconvenience to people's lives. At the same time, as a professional version of a desktop water flosser for the family, different family members use the same handle to replace nozzles with different functions, which will also affect the health of family members. In severe cases, cross-infection may occur, which is not good for health. At the same time, the overall structure of the current desktop water flosser is relatively large, which requires a large area of ​​use. At the same time, the water outlet pipe is not easy to store, resulting in a messy placement of the water outlet pipe. Utility Model Content

Waterway 17, one end of the water inlet waterway 16 is connected to the water tank 2, one end of the water outlet waterway 17 and the other end of the water inlet waterway 16 are both connected to the negative pressure forming area 14, the water inlet end of the left handle 3 and the water inlet end of the right handle 4 are both connected to the other end of the water outlet waterway 17; the first one-way valve 18 and the second one-way valve 19 are respectively provided on the water inlet waterway 16 and the water outlet waterway 17, the first one-way valve 18 allows the water for flushing teeth to flow only from the water inlet waterway 16 to the negative pressure forming area 14, and the second one-way valve 19 allows the water for flushing teeth to flow only from the negative pressure forming area 14 to the water outlet waterway 17. In this embodiment, a volume compression negative pressure is formed in the negative pressure forming area 14, and the liquid is sucked and compressed and discharged by drawing, which is simple, practical and reliable, so that the product of the present invention has a long service life.

[0026] In this embodiment, the water inlet end of the left handle 3 is connected to the water outlet waterway 17 through the left water outlet pipe 25, and the water inlet end of the right handle 4 is connected to the water outlet waterway 17 through the right water outlet pipe 26. In this embodiment, the left and right sides of the base 31 are provided with water pipe storage chambers 33, and the left water outlet pipe 25 and the right water outlet pipe 26 are both spring telescopic pipes. After the left handle 3 and the right handle 4 are placed on the handle bracket 27, the telescopic parts of the left water outlet pipe 25 and the telescopic parts of the right water outlet pipe 26 are located in the water pipe storage chamber 33. When using the invented product, the user can freely stretch the spring telescopic pipe to meet the use needs of different users. At the same time, when not in use, the spring telescopic pipe can be conveniently stored through the water pipe storage chamber 33, keeping the user's table clean.

[0027] In this embodiment, the left and right sides of the seat body 1 are respectively provided with handle brackets 27 adapted to the left handle 3 or the right handle 4. In this embodiment, through the design of the handle bracket 27, the left handle 3 and the right handle 4 can be placed more standardized, ensuring that the user has a tidy use environment, and the handles will not be confused during use.

[0028] In this embodiment, the left handle 3 and the right handle 4 are both provided with a handle switch 28 for controlling the on / off of the water flow of the spray head 5. Through the design of the handle switch 28, the user can freely control the on / off of the water flow of the spray head 5.

[0029] In this embodiment, a power switch 29 and a water pressure regulating knob switch 30 electrically connected to the controller are provided on the side of the seat body 1. When in use, the user needs to turn on the power switch 29 first, and then adjust the required water pressure through the water pressure regulating knob switch 30.

[0030] In this embodiment, a base 31 is provided at the bottom of the seat body 1, and four shockproof suction cups 32 are provided at the bottom of the base 31. Through the four shockproof suction cups 32, when the user places the double-nozzle handle desktop water flosser, the impact on the double-nozzle handle desktop water flosser can be reduced, and the double-nozzle handle desktop water flosser can be well protected. At the same time, the four shockproof suction cups 32 can make the bottoms of the four shockproof suction cups 32 can be well fixed on the smooth table surface, so that the desktop water flosser will not fall.

Through the design of the fixing ring 34, the plunger seal ring 11 can be well fixed in the cavity 9, which well ensures the water outlet stability of the desktop water flosser, and at the same time, the plunger seal ring 11 can be easily replaced during later maintenance.

[0032] The present invention drives the plunger rod 12 to reciprocate by the motor 22. The plunger rod 12 forms a front negative pressure volume area during the frequent reciprocating motions to quickly bring water in and out. The water in the water tank 2 is quickly brought to the outlet of the connecting water pipe through the plunger water supply device. High-pressure pulse water enters the connecting water pipes of the left handle 3 and the right handle 4 at the same time. The user turns on the handle switches at the same time or separately, and the high-pressure pulse water cleans the oral cavity through the nozzle 5. At the same time, during the reciprocating motion of the plunger rod 12, the front negative pressure volume area forms a pulse high water pressure area and then brings out high-pressure pulse water, which meets the user experience requirements of the oral irrigator product.

[0033] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
