For example, the first water pipe 50 and the second water pipe 60 can be set in a form of a combination of a flexible portion and a rigid portion. The rigid portion of the first water pipe 50 can abut the body 10, and the rigid portion of the second water pipe 60 can abut the body 10. The flexible portion of the first water pipe 50 and the flexible portion of the second water pipe 60 are opposite to each other, and the switching element 70 is disposed between the first water pipe 50 and the second water pipe 60, so that the first squeezing portion 72 can match and squeeze the flexible portion of the first water pipe 50 and the second squeezing portion 73 can match and squeeze the flexible portion of the second water pipe 60.

In this embodiment, the first water pipe 50 and the second water pipe 60 are respectively located on two sides of the switching element 70, and the first squeezing portion 72 and the second squeezing portion 73 are spaced apart from and misaligned with each other. The first squeezing portion 72 and the first water pipe 50 are located on a first side of the two sides of the switching element 70, and the second squeezing portion 73 and the second water pipe 60 are located on a second side of the two sides of the switching element 70.

In this embodiment, the body 10 comprises a fixed seat 17 having a receiving groove 171 extending along an up-and-down direction. The receiving groove 171 comprises a first squeezing matching portion 172 and a second squeezing matching portion 173 spaced apart from each other along a left-and-right direction. Each of the first water pipe 50 and the second water pipe 60 pass upward through the receiving groove 171. The switching element 70 is movably disposed in the receiving groove 171, the first water pipe 50 is located between the first squeezing portion 72 and the first squeezing matching portion 172, and the second water pipe 60 is located between the second squeezing portion 73 and the second squeezing matching portion 173.

In this embodiment, the first squeezing matching portion 172 and the second squeezing matching portion 173 are misaligned with each other along a length direction of the receiving groove 171, and the switching element 70 can move along the length direction of the receiving groove 171. Referring FIG. 6, each of the first squeezing matching portion 172 and the second squeezing matching portion 173 are rectangular.

Referring to FIGS. 1 to 7, in this embodiment, the first squeezing portion 72 and the second squeezing portion 73, which are fixedly connected to the push-sliding button portion 71, are a dual-cam structure, and the first squeezing portion 72 and the second squeezing portion 73 are misalignedly disposed on two sides of the push-sliding button portion 71 along the up-and-down direction. A cross section of the push-sliding button portion 71 is elliptical, and an outer surface of the first squeezing portion 72 and an outer surface of the second squeezing portion 73 are arc-shaped. The push-sliding button portion 71 protrudes from the front of the body 10.

The principle of waterway switching of the dual-water-tank water flosser is as follows:

Referring to FIG. 6, the push-sliding button portion 71 is pushed upward to drive the first squeezing portion 72 and the second squeezing portion 73 to move upward at the same time. During the upward movement, the first squeezing portion 72 and the first squeezing matching portion 172 cooperate with each other to squeeze the first water pipe 50 until the first water pipe 50 is completely closed. At this time, a distance between the second squeezing portion 73 and the second squeezing matching portion 173 increases to enable the second water pipe 60 to be opened. A liquid in the second water tank 40 flows through the second water pipe 60, enters the tooth-rinsing component 20, and then flows out from the water nozzle 80.

Referring to FIG. 7, the push-sliding button portion 71 is pushed downward to drive the first squeezing portion 72 and the second squeezing portion 73 to move downward at the same time. During the downward movement, a distance between the first squeezing portion 72 and the first squeezing matching portion 172 increases to enable the first water pipe 50 to be opened. At this time, the second squeezing portion 73 and the second squeezing matching portion 173 cooperate with each other to squeeze the second water pipe 60 until the second water pipe 60 is closed. A liquid in the first water tank 30 flows through the first water pipe 50, enters the tooth-rinsing component 20, and then flows out from the water nozzle 80.

Another embodiment of the present disclosure is different from the previous embodiment in that the switching element 70 can adopt a gasket structure. The gasket structure is located between the first inlet port 91 and the second inlet port 92, and the switching element 70 acts to enable the gasket structure to seal the first inlet port 91, and at this time, the first water pipe 50 is closed and the second water pipe 60 is opened. The switching element 70 acts to enable the gasket structure to seal the second inlet port 92, and at this time, the first water pipe 50 is opened and the second water pipe 60 is closed.

The aforementioned embodiments are merely some embodiments of the present disclosure, and the scope of the disclosure is not limited thereto. Thus, it is intended that the present disclosure cover any modifications and variations of the presently presented embodiments provided they are made without departing from the appended claims and the specification of the present disclosure.
