Abstract

The utility model relates to a miniature dual-purpose steam water pump which comprises a supporting seat, a motor, a connecting rod, an eccentric shaft, a diaphragm, a cover, a base, etc., wherein the motor is fixed to the supporting seat; the connecting rod is sheathed with the eccentric shaft; a bearing is arranged between the connecting rod and the eccentric shaft; an extending-out shaft of the motor is sheathed with the eccentric shaft; the diaphragm is arranged below the supporting seat; the cover is arranged below the diaphragm, and the base is arranged below the cover; the base, the cover and the supporting seat are fixed together. The utility model is characterized in that the miniature dual-purpose steam water pump bases on an elastic diaphragm principle; the motor is started to drive the eccentric shaft and the connecting rod; the miniature dual-purpose steam water pump makes the eccentric shaft do eccentric motion up and down along a central point, making the connecting rod force the diaphragm to stretch and retract up and down, and the miniature dual-purpose steam water pump automatically controls the motion of media (gas or liquid). The utility model provides a very effective valve pump which has the advantages of simple and compact structure, durability and good gas-tightness and water-tightness. The utility model is suitable for pumping and conveying the gas and the liquid.

Description

Miniature air water two-purpose pump

One, affiliated technical field

The utility model belongs to the pump valve technical field, refers in particular to a kind of miniature air water two-purpose pump.

Two, background technique

Chinese patent once disclosed a kind of " miniature water and gas dual-purpose pump " (ZL00239492.8, CN2446306Y, open day: 2001.09.05), with the gentle pump shaft of water pump to being fixed in same motor two ends, the air pump part is being provided with suction port and relief opening on the sidewall of electric machine main shaft, be provided with bowl-shape elastic capsule simultaneously, bowl-shape elastic capsule is fixed in the position of Off center axis on the sidewall of electric machine main shaft and covers suction port and exhaust pipe mouth on the sidewall, form the air pump Seal cage, the off-centre that coexists bowl-shape capsule afterbody is fixed under the guide rod effect on the motor bent axle can periodically apply pressure to capsule, the plectrum of pulling force links to each other, the water that this device energy delivery pressure and aqueous vapor proportioning are stable is gentle, is used for electric atomizing.But because it is to adopt water pump and air pump to realize water, air pump dual functions simultaneously, so structure also is not very simple compactness.

Three, model utility content

The purpose of this utility model is to provide a kind of miniature air water two-purpose pump, and it is simple and compact for structure, and is durable in use, and tightness and water tightness height are applicable to that gas and liquid pumps.

For achieving the above object, the solution that the utility model is taked is: a kind of miniature air water two-purpose pump, fixed electrical machinery in the bearing, connecting rod socket eccentric shaft has bearing between connecting rod and the eccentric shaft, motor projecting shaft socket eccentric shaft, under the bearing diaphragm is set, under the diaphragm lid is set, lid is divided into the bottom set seat, and base, lid and bearing are fixed together.

The utility model is based on a kind of elastic diaphragm principle, and starting electrical machinery drives eccentric shaft and connecting rod, allows eccentric shaft make eccentric motion up and down along a central point, makes connecting rod force diaphragm flexible up and down, controls the motion of media (gas or liquid) automatically.This is a kind of highly effective valve pump, and is simple and compact for structure, durable in use, and tightness and water tightness height are applicable to that gas and liquid pumps.
