Please be simultaneously with reference to Fig. 4, gas flow guiding assembly 100 comprises retaining screw 110, valve 120, outgassing nonreturn valve 130, briquetting 140 and piston body 150.The outgassing nonreturn valve fixed hole 142 of on briquetting 140 a plurality of outgassing nonreturn valves 130 being packed into, the briquetting 140 that will the install outgassing nonreturn valve 130 again valve 120 of packing into uses ultrasonic welding that its welded seal is one.Piston body 150 is passed piston cavity installation position 272 in the piston holder 270, put into piston body installation position A273.The bottom of each piston cavity 151 in the compressed tablet 210 is provided with flexible fastening cover 154 and inlet hole 155, flexible fastening cover 154 is positioned at the bottom surface of each piston cavity 151 and the side intersection all around of piston cavity 151 forms along side downward direction extension all around, adopt side intersection around bottom surface that flexible fastening cover 154 is positioned at each piston cavity 151 and the piston cavity 151 along around the integral processing that forms of side downward direction extension, technology is simple, fabricating cost is low, more compact structure, reliable.Inlet hole 155 is positioned at the center position of each piston cavity 151 bottoms, Dui Ying inlet hole 212 is positioned on the central axis of the corresponding piston body installation position 211 that is provided with on the compressed tablet 210 with it, be fixed with breather check valve 152 on the inlet hole 155, with pack into fixed cover 154 in the piston body 150 of a plurality of piston bodies installation position 211 in the compressed tablet 210, breather check valve 152 constitutes the air inlet gas circuit with the inlet hole 212 of compressed tablet 210, inlet hole 252 by being provided with on the inlet hole 261 that is provided with on the motor 260 and/or the base 250 makes the inlet hole 212 that is provided with on the compressed tablet 210 communicate with ambient air.Because being silicone rubber materials, makes the fixed cover 154 of piston body 150, after being inserted in, can cooperate closely, and inlet hole 212 is airtight on the breather check valve 152 that makes more than 150 piston cavity 151 bottom surfaces of piston body and the compressed tablet 210 with the piston body installation position 211 on the compressed tablet 210.A plurality of piston cavity 151 peripheries of piston body 150 also are provided with piston cavity seal ring 153, can effectively guarantee to increase the tightness between briquetting 140 and the piston cavity 151.
Please see figures.1.and.2 simultaneously, use retaining screw 110 that gas flow guiding assembly 100, transmitting assemblies 200 is fixing.Because the effect of screw 110, make each piston cavity 151 of piston body seal ring 153 crush seals in the piston body 150 of gas flow guiding assembly 100.
Concrete working principle is as follows:
After the motor 260 of transmitting assemblies 200 powered up, motor output shaft 263 began to rotate, and the driving wheel 230 that connects with motor output shaft 263 rotates with motor output shaft 263.Driving wheel 260 upper-end surfaces are provided with an eccentric sphere face 232, and eccentric sphere face 232 sides also are provided with installation guide wall 233.Eccentric sphere face 232 is connected the metal drive shaft 232 oblique angle fits that compressed tablet 210 central parts are pressed into sphere hole 274 on the piston holder 270.So when driving wheel 230 rotated with motor 260, it was the center of circle with the sphere hole on the piston holder 270 274 that driving wheel 230 will drive compressed tablet 210, the eccentric sphere face 232 of driving wheel 260 is done the circumference oscillating motion for radius.The fixed cover 154 of piston body 150 is inserted in the piston body installation position 211 on the compressed tablet 210, and metal drive shaft 232 can be done compression movement by the piston cavity 151 that compressed tablet 210 drives piston body 150 when doing the circumference oscillating motion.
The breather check valve lobe 152 of more than 150 piston cavity 1511 bottom surfaces of piston body, all inlet, outlet one-way valves 121,152 all are normally closed under normal conditions.Breather check valve 152 just can be inhaled and be held when being subjected to negative pressure; When being subjected to malleation, outgassing nonreturn valve 121 just can be blown open.
When metal drive shaft 220 can be done compression movement by the piston cavity 151 that compressed tablet 210 drives piston body 150 when doing the circumference oscillating motion, piston cavity 151 can be pulled on or leaves behind.Motion with a piston cavity 151 is an example, when leaving behind, produces a negative pressure in the piston cavity 151, arrives normally closed outgassing nonreturn valve 130 adhesives on the outgassing nonreturn valve lobe 130 tightr.Simultaneously because negative pressure, the breather check valve lobe 152 of piston body 150 piston cavity 151 bottom surfaces inhaled open, be positioned at the slit of the outer air of motor 260 by inlet hole 261 and motor output shaft 263 and enter base 250 inside.By the inlet hole in the compressed tablet 210 212 air is drawn in the piston cavity 151 again, finishes the air suction process in the piston cavity 151.
After air is inhaled into, it is same because metal drive shaft 220 can be done compression movement by the piston cavity 151 that compressed tablet 210 drives piston body 150 when doing the circumference oscillating motion, piston cavity is upwards promoted, be extruded in the piston cavity 151 and produce a malleation, arrive breather check valve lobe 152 adhesives of piston cavity 151 bottom surfaces tightr, simultaneously because malleation, normally closed clapper 131 on the outgassing nonreturn valve lobe 130 is pushed open, air outputs to valve 120 by piston cavity 151 by a plurality of pores 141 of giving vent to anger, by valve 121 outputs of giving vent to anger, finish the process of piston cavity 151 air pressure output again.
Because piston body 150 comprises two or more piston cavity 151, so a piston cavity 151 necessarily has another piston cavity 151 doing air pressure output in the air pressure suction process.The iterative motion of this a plurality of piston cavity 151 is effectively controlled the discontinuity problem that air pressure is exported, and has guaranteed that air pressure output continuously, steadily.
In whole process, scribble lubricant oil in the eccentric sphere face 232 of driving wheel 230 and the eccentric sphere face 274 of piston body support 270, make both ends of the surface sphere A221, the sphere B222 Ma wiping coefficient of metal drive shaft 220 drop to minimum, and because the spacing string of metal drive shaft that can effectively prevent of the installation at the two ends of metal drive shaft 220 moves the noise problem that more effective reduction is sent by driving mechanism.Also can effectively improve simultaneously product working life.
As required, gas flow guiding assembly 100, transmitting assemblies 200 means of fixation can use screw to fix, and also can use and collude the position, snak link or Plastic fastener are fixed.
The utility model is particularly suitable for being used for the minisize air lift pump of the low power consumption of electronic sphygmomanometer.
