Description

Diaphragm pump

Technical field

The utility model in particular to diaphragm pump.

Background technique

Miniature diaphragm water pump, that is, diaphragm type micro pump, micro pump definition: all composition forms are motor+pump housing, And have two interfaces of one-in-and-one-out on the pump housing, water from water inlet into, discharge outlet goes out, it is all use this form, and compact, Pocket water pump, is all micro pump.

Its working principle is that: the circular motion of motor makes the diaphragm inside water pump do reciprocating by mechanical device, To compress, stretch the air in pump chamber (fixed volume), under unidirectional valve action, it is (practical defeated that positive pressure is formed at discharge outlet The resistance that pressure size is subject to pump drainage mouth out is related with the characteristic of pump)；Vacuum is formed at pump mouth, thus big with the external world Pressure difference is generated between air pressure.Under the action of pressure difference, hydraulic pressure is entered into water inlet, then be discharged from discharge outlet.In motor transmitting Under kinetic energy effect, the continual sucking of water, discharge form more stable flow.

Check valve corresponding with water inlet often only simply uses valve laminated structure, pressure-bearing in present diaphragm pump It is indifferent.

Utility model content

In order to overcome the shortcomings of background technique, the utility model provides diaphragm pump, mainly solves present diaphragm pump In check valve corresponding with water inlet often only simply use valve laminated structure, the not strong problem of bearing capacity.

The technical scheme adopted by the utility model is

Diaphragm pump, including shell and upper cover, the upper lid are equipped with water inlet pipe and outlet pipe, be equipped in the shell every Plate, the partition bottom are equipped with capsule plate, and the relatively described water inlet pipe is equipped with deflector hole on the partition, are additionally provided with valve on the partition Valve, the flap include umbrella leaf, and the umbrella leaf is axially arranged with boss, and the partition is equipped with locating piece, and the boss bottom is set There is the holding tank protruded into for the locating piece, in the deflector hole, the upper cover bottom is equipped with and institute for the umbrella foliage cover State the pressure ring that umbrella leaf upper surface is correspondingly arranged.

Reinforcing rib is additionally provided between the umbrella leaf upper wall and the boss.

The cross section of the boss is triangle, and the cross section of the locating piece is triangle.

Be additionally provided with spacer ring on the partition, the deflector hole is set in the spacer ring, the upper cover bottom be equipped with it is described The pedestal of spacer ring sealing cooperation.

The pressure ring is set to the base bottom, and the pressure ring is correspondingly arranged with the reinforcing rib.

Sealing ring is equipped between the pedestal and the spacer ring opposite face.

The sealing ring upper and lower end face is equipped with sealing bulge loop, is equipped with and the sealing on the bulge loop and the pressure ring The seal groove of bulge loop interference fit.

The beneficial effects of the utility model are: the utility model provides diaphragm pump, flap one corresponding with water inlet pipe Aspect has locating piece positioning, and another aspect the upper end has the pressure ring of upper cover bottom to limit, prevents it to be excessively stressed, increase its use Service life.
