[0002] Oral irrigator is an auxiliary tool for cleaning oral cavity, which uses proper pressure to increase water flow to form high-speed water column under certain pressure to achieve the effect of cleaning teeth.

[0003] Most of the oral irrigators using electromagnetic pump as power source on the market use valve plate in cooperation, but the existing valve plate is mostly designed with the same thickness, which requires electromagnetic pump to use more force to make the valve plate deform to push water flow, resulting in unnecessary loss of electromagnetic pump force and insufficient water flow pressure of the oral irrigator, which affects the cleaning effect of the oral irrigator.

[0004] Based on the above reasons, it is necessary to improve the existing technology. INVENTION CONTENTS

DETAILED DESCRIPTION

[0022] The specific implementation of the utility model will be described in further detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

[0023] Please refer to Figures 1-3 The utility model provides a kind of oral irrigator structure, including pump body 1, the pump body 1 inside is provided with plug rod 10;

[0024] Pump head 2, the pump head 2 is arranged in the pump body 1 side, the pump head 2 has internal cavity, and the water inlet pipeline 20 that is communicated with internal cavity is provided in the pump head 2 side;

[0025] Oral irrigator nozzle 3, the oral irrigator nozzle 3 is connected in the pump head 2 end, and with the internal cavity of the pump head 2 is communicated;

[0026] Valve piece 4, the valve piece 4 is arranged in the pump head 2 inside, and with the plug rod 10 is fixed;

[0027] The top of the plug rod 10 is fixedly provided with a valve seat 5 and the valve piece 4, the valve piece 4 is recessed with a groove portion 40 at the abutting position with the valve seat 5, the valve seat 5 is provided in a bowl shape, the edge of the valve seat 5 is protruded with a first limiting portion 50, the valve piece 4 is provided in a bowl shape, and the periphery thereof is protruded with a second limiting portion 41 abutting with the first limiting portion 50.

[0028] In the above structure, the bowl-shaped valve seat is simple in structure and convenient to manufacture, and the bowl-shaped design can wrap the bottom of the valve piece to enhance the carrying capacity of the valve seat. When the oral irrigator is used, the water flow is input from the water inlet pipe to the valve piece position, the plug rod in the pump body moves to the oral irrigator nozzle position, the plug rod drives the valve seat provided on the top thereof to move upward, the valve seat drives the groove portion provided on the bottom of the valve piece to move upward, the groove portion of the valve piece is recessed to make the wall portion of the valve piece thin, the valve piece is deformed upward under force to push the water flow upward, the thin wall portion of the valve piece reduces the pushing force required for the deformation of the valve piece, thereby increasing the pressure of the plug rod on the water flow, and ensuring that the water flow ejected from the oral irrigator has sufficient pressure to realize the cleaning function.

[0029] Specifically, the first one-way valve 200 is fixedly arranged in the water inlet pipe 20, and the arrangement of the first one-way valve can ensure that the water flow entering the water inlet port cannot flow back, thereby effectively controlling the position of the water flow to prevent backflow.

[0030] Specifically, the second one-way valve 21 is arranged at the communication position between the pump head 2 and the oral irrigator nozzle 3, and the second one-way valve is designed in a regular triangular shape. When the water flow flows from the pump head to the oral irrigator nozzle, the water flow deforms the side walls on both sides of the second one-way valve to the two sides to pass through the water flow, and when the water flow flows from the oral irrigator nozzle to the pump head, the water flow squeezes the side walls on both sides of the second one-way valve to the middle to block the water flow from flowing back from the oral irrigator nozzle to the pump head.

[0031] Specifically, the sealing ring 30 is arranged between the oral irrigator nozzle 3 and the pump head 2, and the sealing ring can ensure that the connection position between the oral irrigator nozzle and the pump head does not have a water leakage phenomenon, thereby increasing the sealing performance of the whole oral irrigator.

[0032] The above is only a preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the technical principles of the present application, and these improvements and refinements should also be regarded as the protection range of the present application.
