Description
Technical field
The utility model 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).
Utility model content
The purpose of the utility model is to provide a kind of check valves for tooth flusher water pump, and open and close speed is relatively fast, property
It can stablize, vibrating noise is small, at low cost, long service life.
To achieve the above objectives, the present invention adopts the following technical solutions:
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
With one-way water outlet valve include: valve deck, the connectivity port being set on pump chamber shell and be folded in the valve deck and connectivity port it
Between valve component, the water inlet pipe and outlet pipe of the pump chamber be all set on valve deck, and the valve component includes a framework, institute
State framework and the water inlet framework for one-way water inlet valve and the water outlet framework for one-way water outlet valve be divided by middle part parting bead, it is described into
It is connected with water inlet tongue piece on the inside of water framework, is connected with water outlet tongue piece on the inside of the water outlet framework；The outlet of the water inlet pipe
Positioned at a 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, in water inlet dispute
It is equipped with pump chamber water inlet at the connectivity port of the piece other side, pump chamber is equipped at the connectivity port of the water outlet tongue piece other side and is discharged
Mouthful；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
Water outlet groove on the outside of edge is equipped at least one connection on the pit baseplane of the connectivity port of the water inlet tongue piece other side
Water inlet groove on the outside of the 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 utility model are: being connected with water inlet tongue piece on the inside of water inlet framework, out
Water outlet tongue piece is connected on the inside of water framework；At least one is equipped on the pit baseplane of the valve deck of water outlet tongue piece side to connect
The water outlet groove on the outside of the water outlet to water outlet tongue piece edge is connect, the pit in the connectivity port of the water inlet tongue piece other side
Baseplane 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, this knot
Structure, for one-way water inlet valve, when pump chamber inner volume becomes smaller to form positive pressure, water inlet tongue piece is close to intake under pressure
Pipe exports side and water inlet pipe is exported closing, and when pump chamber inner volume becomes larger to form negative pressure, water inlet tongue piece is under the action of negative pressure
It is flapped toward the other side and is close to connectivity port pit baseplane, water inlet pipe passes through water inlet tongue piece edge outside, water inlet groove and pump
Chamber connection, 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 again into
Water inlet pipe is exported and is closed by pipe outlet, realizes unidirectional water inflow；One-way water outlet valve is also same principle, is repeated no more.This reality
With novel this into (out) water one-way valve, because the tongue piece is only connected to the inside of framework on one side, tongue piece will not both take off
It falls, and is in free state, being much smaller for driving force ratio spring valve required for reciprocally swinging is critical needed for open and close
The traditional check valve of pressure ratio will be small, and elastic baffle switchs check valve in reciprocating motion and needs the power overcome with regard to small, very
It is suitble to this water pump structure of elastic baffle；Very little, open and close speed are designed into (out) mouth of a river tongue piece reciprocally swinging amplitude is adjustable
Spend it is relatively fast, performance stablize, the vibration of especially tongue piece is small, noise is smaller；Into (out) water groove can water flowing, pit bottom it is flat
Face can support softer tongue piece (such as rubber tongue piece) not make its deformed depression again.
