[0026] Reference Figure 1 According to an embodiment of the present invention, a water flosser includes a handle 100, an air pump 200, and a control system 300. One end of the handle 100 is provided with a water flossing nozzle 400. The handle 100 is provided with a cavity 110 and a liquid input structure 120 for inputting liquid into the cavity 110. An output pipe 180 is provided inside the cavity 110, and the cavity 110 is connected to the water flossing nozzle 400 through the output pipe 180. The air pump 200 is located on the handle 100 and is connected to the air pump 300 through an air delivery pipe 1... Air is supplied to the cavity 110 from the air supply pipe 90. The control system 300 is located on the handle 100. The control system 300 can control the start and stop of the air pump 200, and can control the connection and disconnection between the oral irrigator nozzle 400 and the output pipe 180 or control the opening and closing of the oral irrigator nozzle 400. The distance between the inlet of the output pipe 180 and the inner wall of the cavity 110 away from the oral irrigator nozzle 400 is less than the distance between the outlet of the air supply pipe 190 and the inner wall of the cavity 110 away from the oral irrigator nozzle 400.

[0027] The water flosser provided by this utility model, when the control system 300 controls the connection between the water flosser nozzle 400 and the output pipe 180 to disconnect or close the water flosser nozzle 400, the air pump 200 can supply air and pressurize the cavity 110. During use, the water flosser nozzle 400 is located on the upper side of the cavity 110, and the inlet height of the output pipe 180 is lower than the outlet height of the air supply pipe 190. The control system 300 can control the connection between the water flosser nozzle 400 and the output pipe 180 or open or close the water flosser nozzle 400. At this time, if the cavity 110... If there is no liquid inside the cavity 110, the gas inside the cavity can be ejected from the oral irrigator nozzle 400 for oral irrigation. If there is liquid inside the cavity 110 and the liquid level is higher than the inlet of the output pipe 180, the liquid inside the cavity 110 can be pushed by the gas to the oral irrigator nozzle 400 for spraying. Thus, with the above settings, the oral irrigator provided by this utility model can meet the needs of air jet or liquid spraying with only the air pump 200, which simplifies the structure, reduces costs, helps to control the size, achieves a smaller size, and makes it more convenient for people to use the oral irrigator.

[0028] It is conceivable that since the air pump 200 can pressurize the cavity 110 with air when the water flosser is not in use, the power of the air pump 200 does not need to be too large. By trading time for power, the pressure inside the cavity 110 can also reach the required level. Therefore, the air pump 200 can be a smaller, lower-power model, which helps to control the size and cost of the water flosser, as well as reduce noise and vibration, and improve the user experience.

[0029] When the oral irrigator is normally placed, it is usually placed upright, with the oral irrigator nozzle 400 facing upwards and the cavity 110 located below the oral irrigator nozzle 400.

[0030] Reference Figure 1 and Figure 3 To reduce the risk of short circuits in the control system 300 due to leakage from the cavity 110, according to some embodiments of this invention, the cavity 110 is located at the end of the handle 100 furthest from the water flosser nozzle 400, while the air pump 200 and control system 300 are located on the side of the cavity 110 closer to the water flosser nozzle 400. Thus, when the water flosser is in use or normally stored, the air pump 200 and control system 300 are located on the upper side of the cavity 110. In this case, if leakage occurs in the cavity 110, the leaked liquid can flow downwards under gravity, reducing the probability of the leaked liquid contacting the air pump 200 and control system 300, thereby reducing the risk of short circuits in the control system 300 due to leakage from the cavity 110.

[0031] Reference Figure 1 and Figure 2 According to some embodiments of this utility model, the air supply pipe 190 extends and protrudes into the cavity 110 from the inner wall of the cavity 110 near the nozzle 400, and the air supply pipe 190 is provided with a check valve 500. This arrangement improves the sealing performance between the air pump 200 and the air supply pipe 190, and the check valve 500 prevents liquid in the cavity 110 from flowing back into the air pump 200.

[0032] If the liquid level in the cavity 110 is higher than the outlet of the air supply pipe 190, the air pump 200 will supply air to the liquid in the cavity 110 to form bubbles, thereby enabling the liquid and gas to be mixed and sprayed out from the nozzle.

[0033] Reference Figure 1 and Figure 2According to some embodiments of this utility model, the liquid input structure 120 includes a water inlet 121 and a cover 122. The water inlet 121 is located on the side of the cavity 110 away from the water rinsing nozzle 400 and communicates with the cavity 110. The cover 122 is movably or detachably installed on the handle 100 and can open and close the water inlet 121. With the above configuration, water or cleaning fluid and other liquids can be easily added to the cavity 110.

[0034] In practice, the cover 122 is detachably installed on the handle 100 by screwing, thereby achieving a seal between the cover 122 and the handle 100.

[0035] Reference Figure 1 According to some embodiments of this utility model, the control system 300 includes a switch device 310 and a circuit board 320. The switch device 310 is used to control the connection and disconnection between the dental floss nozzle 400 and the output pipe 180, or to control the opening and closing of the dental floss nozzle 400. The circuit board 320 is electrically connected to the air pump 200 and is used to control the start and stop of the air pump 200. Thus, users can control the dental floss nozzle 400 to spray gas or liquid for dental flossing through the switch device 310, which is convenient to use.

[0036] Reference Figure 1 According to some embodiments of the present invention, the switch device 310 is configured as a push-button valve, thereby the switch device 310 has a simple structure, can be manually pressed to open, and is convenient to use.

[0037] Specifically, when the switch device 310 is installed on the pipe between the rinsing nozzle 400 and the output pipe 180, the switch device 310 can control the on / off connection between the rinsing nozzle 400 and the output pipe 180. When the switch device 310 is installed on the rinsing nozzle 400, the switch device 310 can open and close the rinsing nozzle 400.

[0038] In other embodiments, the switching device 310 may also be configured in other ways. For example, the switching device 310 includes an electromagnetic control valve, which is electrically connected to the circuit board 320. The circuit board 320 is equipped with buttons or a touch panel for controlling the start and stop of the electromagnetic control valve.

[0039] Reference Figure 1 According to some embodiments of the present invention, the handle 100 is provided with a mounting cavity 130, which is located on the side of the cavity 110 near the irrigating nozzle 400. The air pump 200 is located inside the mounting cavity 130, and the control system 300 is at least partially located inside the mounting cavity 130. Thus, the air pump 200 and the control system 300 are at least partially disposed inside the handle 100, so as to protect the air pump 200 and the control system 300 through the handle 100.

[0040] Reference Figure 1 and Figure 3 According to some embodiments of this utility model, the handle 100 includes a first housing 100a, a second housing 100b, and a transition member 100c. The first housing 100a is inserted into one end of the transition member 100c, and the second housing 100b is inserted into and sealed to the transition member 100c. The oral irrigator nozzle 400 is installed at the end of the first housing 100a facing away from the second housing 100b. The mounting cavity 130 is formed by the first housing 100a and the transition member 100c, and the receiving cavity 110 is formed by the second housing 100b and the transition member 100c. This configuration facilitates the production and assembly of the oral irrigator and reduces costs.

[0041] Reference Figure 1 and Figure 3 According to some embodiments of this utility model, the first housing 100a includes a head 140 and a middle housing 150. The head 140 is inserted into one end of the middle housing 150, and the middle housing 150 is inserted into the transition piece 100c. The oral irrigator nozzle 400 is installed on the head 140. With the above configuration, the oral irrigator can be easily manufactured and assembled, and the cost can be reduced.

[0042] Reference Figure 1 and Figure 3 According to some embodiments of this utility model, the transition member 100c is provided with a first connecting pipe 160, which communicates with the output pipe 180. The head 140 is provided with a second connecting pipe 170, which is connected to the first connecting pipe 160 via a pipe. The second connecting pipe 170 is connected to the oral irrigator nozzle 400. This arrangement facilitates the connection between the output pipe 180 and the oral irrigator nozzle, simplifying assembly.

[0043] Reference Figure 1 According to some embodiments of this utility model, the control system 300 further includes a battery 330, which is disposed on the handle 100. The handle 100 is electrically connected to the circuit board 320, and the battery 330 can supply power to the air pump 200 and the circuit board 320. The battery 330 can be configured as a rechargeable non-removable type or as a removable type.

[0044] Of course, it is conceivable that in other embodiments, the water flosser may also power the circuit board 320 and the air pump 200 via a wireless power supply or a power cord, in which case the battery 330 may or may not be configured.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
