Abstract
The utility model relates to a miniature diaphragm pump with multiply air chambers, which is composed of an electric motor (2), a pump body (5) and a pump cover (11). The pump body comprises an eccentric component (3), an inclined shaft (4), an umbrella-shaped wheel (6) and an elastic bowl (15); a valve gate piece (10), air gate holes (9, 13) and an air fountain (12) are arranged on the pump cover (11); more than two pump hangs (7) are arranged on the umbrella-shaped wheel (6); the umbrella-shaped wheel (6), the elastic bowl and the pump cover form air chambers (14) with corresponding quantity. The umbrella-shaped wheel swings according to a definite rule; all the air chambers rapidly carry out air inlet and air jet, generating high-pressure air. Compared with the existing electromagnetic miniature air compression pumps, the utility model has the advantages of large air jet quantity, high air pressure, power consumption saving and general purpose for alternating current-direct current.
Description
The utility model relates to a kind of many air chambers gas compression pump, particularly a kind of rotary diaphragm pump.
Existing minitype gas compressor pump adopts the electromagnetic type structure mostly, its structure is the runout of mounted permanent magnet in the open core of coil, and it is raised one's arm to go up and connects the bowl-shape film of an elasticity, it and air chamber composition active chamber, active chamber has air inlet/outlet, and corresponding one-way cock sheet is housed respectively on air inlet/outlet.When runout was swung in magnetic field, the cycle elasticity modification by bowl-shape film produced pressurized gas.Because the runout of this working method is generally all smaller, thereby discharge tolerance is few, and gas pressure is also very little, inefficiency, and must not satisfy usage requirement with the former power supply of Ac.
The purpose of this utility model is a kind of new minitype gas compressor pump of design, exists exhaust pressure to hang down the air displacement minor issue to overcome present electromagnetic gas compressor pump.
The design's scheme is, many air chambers miniature diaphragm pump, it is made up of motor, the pump housing and pump cover, it is characterized in that the pump housing by offset assembly, inclined shaft, umbrella shape wheel, pump hangs down and the elasticity bowl is formed, offset assembly is affixed with the inclined shaft end on one side, and the inclined shaft the other end places the umbrella shape caster middle and affixed, establishes 2 above pumps on the wheel face of umbrella shape wheel at interval and hangs down and the affixed elasticity bowl of outer rim, establish valve port, valve sheet and air nozzle on the pump cover, valve sheet, pump hang down, elasticity bowl and pump cover surround an air chamber.
The advantage of such scheme is to adopt motor to be used as power, when motor shaft rotates a week, 3 air chambers on the pump housing are all successively finished one time air inlet compression exhaust process, working efficiency improves greatly, and air displacement heightens, the pressure height, compact structure, volume is little, power consumptive province, but and characteristics such as power of alterating and direct current is general.
Fig. 1 is the utility model overall structure sectional drawing.
Fig. 2 is that the A of Fig. 1 is to view.
Among the above-mentioned figure, 1 is power line, and 2 is motor, and 3 is offset assembly, and 4 is inclined shaft, and 5 is the pump housing, 6 are the umbrella shape wheel, and 7 for pump hangs down, and 8 is the pump circle, and 9 is inlet hole, and 10 is valve sheet, 11 is pump cover, and 12 is air nozzle, and 13 for pressurized gas portals, and 14 is air chamber, and 15 is the elasticity bowl.
Embodiment's structure and working procedure are described below in conjunction with accompanying drawing.
The utility model is made up of miniature motor (2), the pump housing (5) and pump cover (11), miniature motor can be AC motor or direct current generator, it is directly affixed that the pump housing (5) includes offset assembly (3), inclined shaft (4), umbrella shape wheel (6), pump vertical (7) and elasticity bowl (15), offset assembly (3) and motor (2) axle, inclined shaft (4) one ends and offset assembly (3) are affixed, the defeated pin internal fixation of its other end and umbrella shape wheel (6).On umbrella shape wheel (6) wheel 2 above pumps are set at interval and hang down (7), present embodiment is provided with 3 pumps and hangs down (7), and 3 valve sheets (10) are arranged under the pump cover (11), and forms 3 air chambers with pump cover (11).As shown in Figure 1, every vertical affixed elasticity bowl of (7) outer rim (15) of pump, establish valve port (9), valve sheet (10) and air nozzle (12) on the pump cover (11), valve sheet (10) passes pump cover (11) and hangs down (7) corresponding end face expansion for opening and closing the diaphragm of inlet hole (9) with pump, elasticity bowl (15) also has pressurized gas to portal (13), every pressurized gas portal (13) communicate with air nozzle (12).Pressurized gas portal (13) the exhaust diaphragm is arranged, when air inlet, the exhaust diaphragm is close to pressurized gas and is portalled on (13), does not allow the pressed gas in the exhaust port to blow back into air chamber, when the air chamber exhaust, the exhaust diaphragm is open, pressurized gas enters air nozzle (12).
Referring to accompanying drawing 1,2 describe the present embodiment working procedure, after motor (2) energising, umbrella shape wheel (6) is subjected to offset assembly (3) effect, swing according to certain rules, be arranged at umbrella shape wheel (6) last 3 pumps and hang down (7) respectively along axially making back and forth movement, as shown in Figure 1, if certain moment, first pump hung down (7) in minimum point, air chamber (14) air pressure is low, valve sheet (10) is inhaled out, air enters air chamber by inlet hole (9), second vertical (7) place air chamber (14) of pump mediates, and the 3rd pump vertical (7) is in the extreme higher position, and air is compressed, valve sheet (10) is pressed to pump cover (11) by air pressure and is stopped up inlet hole (9), and this moment, pressurized gas was by air outlet hole (13).Push the exhaust diaphragm open, pressurized gas is pressed towards air nozzle, forms the high pressure air ejection, and motor speed is higher, 3 air chamber air inlets, and exhaust velocity is faster, air nozzle.Gas output is big more, and the air pressure of giving vent to anger is also high more.
