Abstract
The utility model relates to an electromagnetic air pump with high flow and negative pressure. The utility model is mainly characterized in that the dimension of cylinder elements is prolonged, and a concave groove is arranged on the front face of a leather cup. The improved electromagnetic air pump has the advantages of obvious increase of the zero load flow and the negative pressure, good shock resistance and shock resistance performance, small size, light weight, long service life, low cost are and low noise, and is completely suitable for the requirement of the air source in the analyzing, testing and bacteria breeding equipment in departments, such as environmental protection, mining, metallurgy, petrochemical industry, medical hygiene, public security, etc.
Description
The utility model belongs to the improvement to Electromagnetic air pump.
In recent years; along with China's economic construction and science and technology development; tasks such as the detection of departments such as, health care metallurgical in environmental protection, mining and public transit system, assay, bacterium cultivation are heavy; but owing to little for finishing the electromagnetic pump no load discharge that above-mentioned purpose is installed on the food apparatus; have only about 2 liters; negative pressure value is low, can only be controlled between 80～90mmHG, does not satisfy needs.In addition, existing electromagnetic pump volume is big, weight is big, and it is many to consume raw material, and vibration strength and impact resistance are poor.
It is big that the purpose of this utility model provides a kind of no load discharge, negative pressure value height, the Electromagnetic air pump that vibration strength and impact resistance are good.
For reaching this purpose, the present invention extends cylinder dimensions, than former parts lengthening 5～7mm, makes the air-capacitor amount strengthen the also corresponding increase of throughput; Former leather cup front is a plane, and the utility model leather cup front is provided with a circle groove, and purpose is to increase to shrink elasticity, increases active face.Leather cup system makes with rubber or elastomeric plastics.
Fig. 1 is the Electromagnetic air pump structural drawing.1 is shell among the figure, the 3rd, annex, the 4th, the screw mold insert, the 5th, ply-yarn drill, the 6th, screw thread mold insert, the 7th, cylinder, the 8th, sealing gasket, the 9th, valve, the 10th, screw, plain cushion, the 11st, sleeve pipe, the 12nd, fork, the 13rd, screw, nut, the 14th, leather cup, the 15th, electromagnet core, the 16th, skeleton, the 17th, electromagnetic wire bag, the 18th, magnet steel, the 19th, power line, the 20th, plug.
Fig. 2 is the Electromagnetic air pump profile.The 2nd, cover plate, the 5th, ply-yarn drill, the 11st, sleeve pipe, the 22nd, compression leg, the 23rd, screw.
Fig. 3 is cylinder figure.The 21st, air door, the 24th, air door pressure pad.Wherein last figure is cylinder and leather cup socket face figure; Middle figure is the cylinder profile pattern; Figure below is the cylinder ground plan.
This Electromagnetic air pump is provided with the two-way source of the gas, both can in parallelly use, connects and use, and also can use as two-way separately. The present invention utilizes electromagnetic action. After the energising, electromagnetism promotes fork (12) move left and right, and fork (12) drives leather cup (14) advance and retreat, and the advance and retreat of leather cup (14) are impelled the air door opening and closing in the cylinder, and produce source of the gas, reach air-breathing and degassing function.
The invention has the advantages that:
1. no load discharge is big.Can reach more than 3.5 liters according to user's needs per minute; Per minute can reach more than 5 liters when two-way was in parallel.
2. negative pressure value is big.Negative pressure value 〉=130mmHg reaches as high as 150mmHg.
3. earthquake-proof function of the present invention is good, and impact resistance is also good.
4. the present invention is in light weight, noise is low, the life-span is long, continuous operation for a long time.
5. volume of the present invention is little, housing thin, can save raw material.
Embodiment: the present invention is good through test effect.The no load discharge per minute reaches more than 3.5 liters, and negative pressure 〉=130mmHg can reach 180mmHg; Vibration strength 10g50Hz～100Hz; Impact resistance is 25g60 time/minute; Temperature using scope-25 ℃～50 ℃; Relative temperature≤70%; Operating voltage is 220v ± 10%50Hz; Power consumpiton 8W; External dimension are 53 * 125 * 125mm; Weight is 0.65Kg.
