[0028] Please refer to Figs. 1 to 4 shown, which shows the specific structure of the preferred embodiment of the utility model, including the body 10.

[0029] The body 10 is of elastic material, and the body 10 has a water passing cavity 11, the water passing cavity 11 has an input end 101 and an output end 102, the output end 102 is integrally formed with a switch part 12 that can open or close the output end 102, and the switch part is of elastic material; in this embodiment, the body 10 and the switch part 12 are both of silica gel material, and they are of the same material, and the switch part 12 is integrally formed on the output end 102, so that the product can obtain the final product through one-time molding, effectively improving the production efficiency; in addition, the water passing cavity 11 includes a water inlet section 111 and a water outlet section 112 that are in communication with each other, the water inlet section 111 is close to the input end 101, the water outlet section 112 is close to the output end 102, and the inner diameter of the water outlet section 112 gradually decreases from outside to inside, the design of the inner diameter of the water outlet section 112 is beneficial to the pressurization of the water flow when the water flow enters the water outlet section 112, facilitating the opening of the output end 102 by the switch part 12; and the switch part 12 is two, and the two switch parts 12 extend to the center position of the water passing cavity 11 from the upper and lower sidewalls of the water passing cavity 11 respectively; and the body 10 is provided with a movable cavity 13, the movable cavity 13 is in communication with the output end 102, and the aforementioned switch part 12 extends into the movable cavity 13, the movable cavity 13 provides a moving space for the switch part 12, which is more conducive to the opening of the output end 102 by the switch part 12.

[0030] The working principle of this embodiment is described in detail as follows:

[0031] Firstly, when the water flow enters the water passing cavity 11 through the input end 101, it reaches the water outlet section 112 from the water inlet section 111, and the water pressure gradually increases during the flow in the water outlet section 112, so that the water pressure of the water flow is sufficient to open the switch part 12, thereby opening the output end 102 by the switch part 12, and then the water flow flows out of the output end 102. When the water flow enters the movable cavity 13, the water pressure of the water flow makes the closing force of the switch part 13 greater, so that the water flow cannot enter the water passing cavity 11 from the movable cavity 13, so that the valve realizes the one-way movement of the water flow.

[0032] The integrated valve can be used on the oral irrigator, the water pump of the oral irrigator is communicated with two integrated valves, the output end 102 of one integrated valve is communicated with the water inlet end 21 of the water pump 20, the input end 101 of the other integrated valve is communicated with the water outlet end 22 of the water pump 20, after the water pump 20 is started, the water inlet 31 of the oral irrigator starts to suck water from the water tank and forms a water flow in the water inlet 31, the input end 101 of one integrated valve is communicated with the water inlet 31, the water flow flows into the input end 101 of one integrated valve from the water inlet 31, the switch part 12 made of elastic material is opened under the water pressure of the water flow, so that the water flow flows into the water pump 20 from the output end 102 of one integrated valve through the water inlet end 21 of the water pump 20, the water flow flows into the input end 101 of the other integrated valve from the water outlet end 22 of the water pump 20, after the switch part 12 of the other integrated valve is opened under the water pressure of the water flow, the water flow enters the water outlet 32 and flows out to the outside from the water outlet 32, after the water pump is closed, there is residual water in the water outlet 32 and the water pump 20, the residual water enters the movable cavity 13 of the corresponding integrated valve, at this time, the residual water is pressed on the switch part 13, the closing force of the switch part 13 is greater, the switch part 13 is tightly closed, so that the residual water cannot enter the water flow cavity 11 from the movable cavity 13, so that the valve realizes one-way movement of the water flow, and the anti-backflow effect is realized in the oral irrigator.

[0033] The utility model discloses the design emphasis is through setting up a water flow cavity on the body, and then forming a switch part which can open or close the output end on the output end, the switch part is made of elastic material, so that when the water flow enters the water flow cavity, the switch part opens the output end, and the water flow can smoothly pass through the water flow cavity, realizing the function of opening and closing the pipeline, and the integrated structure is simple, does not need to be assembled, saves the assembly cost, reduces the production cost, and there is no spare part, effectively reduces the damage of spare part and causes the valve to be unable to use, effectively prolongs the service life.

[0034] The above is only the preferred embodiment of the utility model, and does not limit the technical range of the utility model, so any slight modification, equivalent change and modification according to the technical essence of the utility model are still within the technical range of the utility model.
