The top of described upper cover is provided with upper cover outlet nozzle.
The top of described valve plate is provided with the first suction chamber and the second suction chamber, enters the first suction chamber after air-flow enters the second suction chamber through the first guiding gutter, and the air-flow in the first suction chamber gathers through the second guiding gutter and enters upper cover outlet nozzle.
Be provided with sealed groove in the middle of the bottom of described bottom, sealing gasket is arranged in sealed groove, and the outer surface of described bottom is also provided with bottom air inlet nozzle.
Described barrier film and umbrella fourth adopt quality of rubber materials to make.
Compared with prior art, the utility model at least has the following advantages:
By above-mentioned the technical solution of the utility model, design dual suction chamber, be respectively the first suction chamber and the second suction chamber, the second suction chamber is utilized to cover umbrella fourth to reduce noise, enter the first suction chamber again by the first guiding gutter after simultaneously air-flow enters the second suction chamber, the air-flow then in the first suction chamber gathers through the second guiding gutter again and enters outlet nozzle, thus reaches the effect reducing air pump noise, and by connecting two guiding gutters outward at suction chamber, considerably increase the throughput of micropump.
Accompanying drawing explanation
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of a kind of low noise micropump that the utility model embodiment provides;
Fig. 2 is the mounting structure schematic diagram of the upper cover of a kind of low noise micropump that the utility model embodiment provides, valve plate and umbrella fourth;
Fig. 3 is the valve board structure schematic diagram of a kind of low noise micropump that the utility model embodiment provides.
Embodiment
Below in conjunction with the accompanying drawing in the utility model, be clearly and completely described the technological scheme in the utility model, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-Figure 3, for a kind of low noise micropump that the utility model embodiment proposes, this micropump forms by passing through upper cover 2, valve plate 4, cylinder body 6, bottom 8 and the motor 13 that long screw 1 is fixedly connected with, it is characterized in that: assembled by umbrella fourth 3 between upper cover 2 and valve plate 4, barrier film 5 is installed with between cylinder body 6 and valve plate 4, be provided with rocker 7 between cylinder body 6 and bottom 8, rocker 7 comprises the air inlet system that three inlet holes are formed by connecting; Be provided with eccentric wheel 11 above the rotating shaft of motor 13, be provided with draw point 9 and steel ball 10 in the inclined hole of eccentric wheel 11, the other end of draw point 9, steel ball 10 is fixedly connected in the middle part of rocker 7, and rocker 7 and barrier film 5 be reciprocal upper and lower swing in cylinder body 6.
Further, the top of upper cover 2 is provided with upper cover outlet nozzle 21.
Preferably, the top of valve plate 4 is provided with the first suction chamber 41 and the second suction chamber 42, enters air-flow in the first suction chamber 41, first suction chamber 41 to gather through the second guiding gutter 44 and enter upper cover outlet nozzle 21 after air-flow enters the second suction chamber 42 through the first guiding gutter 43.
Preferably, be provided with sealed groove in the middle of the bottom of bottom 8, sealing gasket 12 is arranged in sealed groove, and the outer surface of bottom 8 is also provided with bottom air inlet nozzle 82.
Preferably, barrier film 5 and umbrella fourth 3 adopt quality of rubber materials to make.
Be described as follows below in conjunction with the working procedure of accompanying drawing to this device:
When vacuum pump leads to direct current work, after motor 13 is energized and rotates, band movable eccentric wheel 11 rotates together, eccentric wheel 11 drives the draw point 9 of inclined hole internal fixtion on rocker 7 and steel ball 10 to move, and causes rocker 7 and diaphragm of rubber 5 in cylinder body 6, do reciprocal upper and lower oscillating motion.Diaphragm of rubber 5 has three cylinders, bleed at bottom air inlet nozzle 82 when barrier film 5 moves up and down, enter in barrier film 5 by three inlet hole air inlets in the middle of rocker 7, then pressurized gas is discharged through valve plate 4, rubber umbrella fourth 3 and upper cover outlet nozzle 21, diaphragm of rubber 5 does reciprocatory motion, thus compression, air in stretching pump chamber, form vacuum at bottom air inlet nozzle 82, form positive pressure at upper cover outlet nozzle 21 place.
