Abstract
The present invention introduces an air supply pump which is composed of a motor, an air pump, etc. The present invention is characterized in that an inlet of an air inlet chamber of the air pump is provided with an air filtering cylinder; the cylinder bottom is provided with a silencing filtering layer which enable air to directly enter the air inlet chamber after the air is filtered. Meanwhile, sealing sleeves whose motion states are opposite are arranged on a piston and a piston sleeve; thus, the pressure of the air pump is almost zero at the time of operation, and the noise and the power consumption are greatly reduced. The output end of the pump is connected with a one-way check valve, so air or liquid can be prevented from flowing back.
Description
The present invention relates to a kind of air feed pump.
Existing air pump generally all is to work under the constant air amount change pressure state, and noise is bigger, and power consumption is also big.
It is little to the objective of the invention is to design a kind of noise, and power consumption is little, easy to operate, can be widely used in the minitype air-supply pump of each peasant household and family.
Structural feature of the present invention has reached above-mentioned purpose: it comprises direct current generator, circuit for controlling motor, air pump and piston, it is characterized in that being equipped with on the motor shaft eccentric wheel, eccentric wheel links to each other with piston rod, air pump suction chamber ingress is provided with air filtration cartridge, and there is the noise reduction filter layer at the tube end, and the hole of a fixing seal sheet is respectively arranged on piston nose and the piston sleeve, drive fit has diaphragm seal in the hole, is distributed with air inlet or air outlet hole around the hole in the topped scope of diaphragm seal.
Above-mentioned structural feature, can make air directly enter air pump after filtering, when piston moves ahead, diaphragm seal sealing on it, and the diaphragm seal on the piston sleeve is opened, piston extrudes the gas in the cylinder, when piston retreats, diaphragm seal sealing on the piston sleeve, and the diaphragm seal on the piston is opened, can guarantee that thus the air pressure of this air feed pump when work is near barometric pressure, be air pressure in the air chamber does not contain pressure, thereby changed air pump, again because air directly enters air chamber after through the filter cartridge noise reduction usually in the working state of constant air amount change pressure, greatly reduce air pump fricative noise of air when work, also greatly reduce the power consumption of air pump simultaneously.
In order to prevent that gas from pouring in down a chimney into the pump housing, this air feed pump output terminal is connected to an one way stop peturn valve, to guarantee that the gas folk prescription is to output.
On the said structure basis, this air feed pump is provided with a miniature bearing again between eccentric shaft and connecting rod, make link motion lighter and handier.
The present invention also can be used as solution feed pump, as long as air filtration cartridge is changed the liquid joint.
Because the present invention structurally, can be operated under the normal pressure it, and have that noise is little, advantage that low, the gas of power consumption or liquid do not reflux.
Describe the present invention in detail below in conjunction with accompanying drawing:
Fig. 1 plan view
Fig. 2 plan view
This air feed pump is made of control circuit, motor and the air pump housing, motor is fixed on the pump housing base plate, the pump housing is made of air chamber 1, eccentric wheel 2, connecting rod 3, miniature bearing 4, piston 5, piston head 6, output gas connection 7, air chamber cover 8, one- way valve 9,10 and the air filtration cartridge 11 that is fixed on the air chamber wall, motor 12 is fixed on the base plate 20 of gas pump, motor shaft 13 is connected with eccentric wheel wheel 2, eccentric shaft and connecting rod 3 are connected, in order to reduce friction and increase rotating speed, the connecting rod afterbody has a miniature bearing 14.Connecting rod one end links to each other with eccentric wheel, and the other end and piston 5 are connected.Piston 5 slides with piston sleeve 6 drive fits, and piston sleeve 6 is threaded with air chamber cover 7, and piston and piston sleeve central authorities all are attached with diaphragm seal 15,16.Air pump output terminal 17 1 ends are fixed on the air chamber cover 8, and the other end closely is connected with conduit 19.The other end of conduit links to each other with the interior one-way valve 19 that connects, and this one-way valve joins with external one-way valve again.
On suction chamber 1 wall, a hole is arranged, its internal fixation has air filtration cartridge 20.Single face copper mesh filter screen is arranged at its bottom, and foam is housed in the net, is used for filtered air and abates the noise.
This air feed pump can be used for family and breeds fish to the fish jar oxygen supply and be used for peasant household spray wine liquid pesticidal.
