Description
Technical field
The present invention relates to check valve, especially a kind of check valve for electric tooth washing device water pump.
Background technique
Check valve be liquid stream or air-flow can only a direction flowing and be unable to the directional control valve of reverse flow.It is most common
It is spring check valve, its working principle is that: when liquid stream or air-flow forward flow, compressed liquid or air overcome 41 power of spring
Ball of Non-return 42 is set to remove valve port, Open valve；When liquid stream or air-flow want reverse flow, make under the effect of 41 power of spring
Ball of Non-return 42 returns to valve port, and valve port closes (referring to Fig. 1).When this check valve is applied on tooth flusher, due to electronic punching
The water piston of tooth device high speed reciprocating motion under the driving of eccentric wheel 2 and drive rod 1, water feeding one-way valve valve ball 32 and water outlet are single
It is very big to vibrating noise of the valve valve ball 42 in switching process；Spring 31,41 flexibility decreases is used for a long time, sealing performance is unstable
It is fixed；Switch water-in and water-out check valve 3,4 also needs to overcome the starting elastic force of spring 31,41, this allows for water-in and water-out check valve 3,4
It is not high to switch sensitivity, but also to lose certain starting pressure (critical pressure).(referring to Fig. 1).
Summary of the invention
The object of the present invention is to provide a kind of check valves for tooth flusher water pump, and open and close speed is relatively fast, and performance is steady
Fixed, vibrating noise is small, at low cost, long service life.
To achieve the above object, the present invention adopts the following technical scheme:
A kind of check valve for tooth flusher water pump, including one-way water inlet valve and one-way water outlet valve, the one-way water inlet valve and list
Include: valve deck, the connectivity port being set on pump chamber shell to outlet valve and is folded between the valve deck and connectivity port
Valve component, the water inlet pipe and outlet pipe of the pump chamber are all set on valve deck, and the valve component includes a framework, the frame
Body is divided into the water inlet framework for one-way water inlet valve and the water outlet framework for one-way water outlet valve, the water inlet frame by middle part parting bead
It is connected with water inlet tongue piece on the inside of body, is connected with water outlet tongue piece on the inside of the water outlet framework；The outlet of the water inlet pipe is located at
One middle side part of water inlet tongue piece, the entrance of the outlet pipe is located at a middle side part of water outlet tongue piece, another in water inlet tongue piece
It is equipped with pump chamber water inlet at the connectivity port of side, pump chamber water outlet is equipped at the connectivity port of the water outlet tongue piece other side；
At least one connection water outlet is equipped on the pit baseplane of the valve deck of water outlet tongue piece side to water outlet tongue piece side
Water outlet groove along outside is equipped at least one connection institute on the pit baseplane of the connectivity port of the water inlet tongue piece other side
State the water inlet groove on the outside of pump chamber water inlet to water inlet tongue piece edge.
The water inlet framework, water outlet framework, water inlet tongue piece, water outlet tongue piece are integrally to tie made of rubber material
Structure.
The tooth flusher water pump includes front pump case and rear portion pump case, be installed between front pump case and rear portion pump case by
Pump case is divided into the elastic baffle of the pump chamber and cavity, the middle part of the elastic baffle and the drive rod that is arranged in cavity
Front end connection, the drive rod are driven by motor and move back and forth.
Compared with prior art the beneficial effects of the present invention are: being connected with water inlet tongue piece on the inside of water inlet framework, it is discharged frame
Water outlet tongue piece is connected on the inside of body；At least one connection institute is equipped on the pit baseplane of the valve deck of water outlet tongue piece side
The water outlet groove on the outside of water outlet to water outlet tongue piece edge is stated, the pit bottom in the connectivity port of the water inlet tongue piece other side is flat
Face is equipped with the water inlet groove on the outside of at least one connection pump chamber water inlet to water inlet tongue piece edge, and this structure is taken
For one-way water inlet valve, when pump chamber inner volume becomes smaller to form positive pressure, water inlet tongue piece is close to water inlet pipe under pressure and is gone out
Water inlet pipe is exported and is closed by mouth side, and when pump chamber inner volume becomes larger to form negative pressure, water inlet tongue piece is flapped toward under the action of negative pressure
The other side and be close to connectivity port pit baseplane, water inlet pipe by the outside of water inlet tongue piece edge, water inlet groove and pump chamber company
It is logical, when pump chamber inner volume becomes smaller to form positive pressure again, the backswing under pressure of water inlet tongue piece and be close to water inlet pipe again
Water inlet pipe is exported and is closed by outlet, realizes unidirectional water inflow；One-way water outlet valve is also same principle, is repeated no more.Of the invention
It is this into (out) water one-way valve because the tongue piece is only connected to the inside of framework on one side, tongue piece not only be will not fall off, but also be in
Free state, driving force ratio spring valve required for reciprocally swinging are much smaller, the tradition of critical pressure ratio needed for open and close
Check valve will be small, elastic baffle switchs check valve in reciprocating motion and needs the power that overcomes just small, be very suitable to elasticity every
This water pump structure of plate；It is designed into very little into (out) mouth of a river tongue piece reciprocally swinging amplitude is adjustable, open and close speed is relatively
Fastly, performance is stablized, and the vibration of especially tongue piece is small, noise is smaller；It can water flowing, pit baseplane but also branch into (out) water groove
Supportting softer tongue piece (such as rubber tongue piece) does not make its deformed depression.
