Problems solved by technology

The disadvantage is that the solenoid solenoid valve consumes a lot of power, especially for electronic sphygmomanometers using dry batteries, the battery life is poor, and at the same time, it will also have a certain impact on environmental pollution
Moreover, because the total volume of the air pump and solenoid valve is too large, it is impossible to miniaturize the end product

Embodiment 1

[0022] Such as figure 1 , 2 As shown, a micro air pump suitable for electronic sphygmomanometers includes an inflation and deflation mechanism, an inflation component and a power component. The inflation and deflation mechanism includes an upper cover 2, a lower cover 6, and a The movable spool assembly and the rubber one-way valve 5 in between, the upper cover 2 is provided with an air outlet 201 and an air release hole 202, the movable spool assembly includes a spool 4 and a rubber reducing valve sleeved inside the spool 4 Shock pad 3; the inflatable part includes a cylinder 7, a cylinder holder 8 and a swing rod assembly 9, the number of the cylinder 7 is two and assembled on the cylinder holder 8, and the end of the cylinder 7 is sleeved on the swing On the rod assembly 9; the power part includes a motor 14, a motor fixing seat 13 and an eccentric shaft 11, and one end of the shaft center of the swing rod assembly 9 is also inserted into the oblique hole of the eccentric ...

Embodiment 2

[0024] Such as image 3 , 4 , 5, and 6, further, the movable valve core assembly and the air outlet hole 201 form an external air chamber, and the upper cover 2, the movable valve core assembly, the rubber check valve 5 and the lower cover 6 form an internal air chamber, A matching gap 203 is provided between the movable valve core assembly and the upper cover, and the external air chamber communicates with the internal air chamber through the gap 203 .

[0025] Further, the lower cover 6 is provided with six first air inlet holes 602 and a tiny air release groove 601, the number of the rubber one-way valve 5 is two and assembled on the lower cover 6, the rubber one-way valve 5 The canopy cover covers the first air intake hole 602 and the tiny air leakage groove 601.

[0026] Further, the upper cover 2 and the lower cover 6 are fixed together by welding, and the lower cover 6 is fixed together by the cylinder fixing seat 8 of the stud 1 and the motor fixing seat 13 .

[002...

Embodiment 3

[0029] Such as figure 1 , 7 As shown, further, the cylinder 7 includes a cylinder cavity 701 and a cylinder valve 702. When the cylinder cavity 701 is driven upward by the swing rod assembly 9, the cylinder valve 702 will close the cylinder fixing seat 8, so that the gas in the cylinder chamber 701 flushes through the rubber check valve 5 of the lower cover 6 and communicates with the air outlet 201 of the upper cover 2 to complete an inflation; the rubber on the lower cover 6 When the one-way valve 5 is closed naturally, the cylinder flap 702 will open the second air intake hole 801 of the cylinder fixing seat 8 to realize the air intake of the cylinder cavity 701 .

[0030] The structure is purely mechanical, does not need to consume electric energy, can realize the seamless connection of inflation and exhaust, is small in size, and is suitable for portable medical products.

Abstract

The invention provides a miniature air pump suitable for an electronic sphygmomanometer, and relates to the field of electronic sphygmomanometers. The miniature air pump comprises an inflation and deflation mechanism, an inflation part and a power part, wherein the inflation and deflation mechanism comprises an upper cover, a lower cover, and a movable valve core assembly and rubber one-way valveslocated between the upper cover and the lower cover; the inflation part comprises air cylinders, an air cylinder fixing seat and a swing rod assembly, the two air cylinders are arranged and assembledon the air cylinder fixing seat, and the tail ends of the air cylinders are arranged on the swing rod assembly in a sleeving mode; and the power part comprises a motor, a motor fixing seat and an eccentric shaft, one end of the axis of the swing rod assembly is inserted into an inclined hole of the eccentric shaft of the power part, and the motor drives the eccentric shaft to rotate to drive theair cylinders to carry out piston up and down reciprocating movement to output air. The miniature air pump suitable for the electronic sphygmomanometer is provided, and the structure is of a purely mechanical structure, does not need to consume electric energy, can achieve seamless connection of air inflation and air exhaust, is small in size and is suitable for a portable medical product.

Description

technical field [0001] The invention relates to the field of electronic sphygmomanometers, in particular to a miniature air pump suitable for electronic sphygmomanometers. Background technique [0002] At present, when people use an electronic sphygmomanometer to measure blood pressure, after the measurement is completed, the compressed gas in the air bag of the cuff or wristband needs to be discharged. At present, people use a solenoid solenoid valve in the electronic sphygmomanometer. Its disadvantage is that the solenoid valve consumes a lot of power, especially for electronic sphygmomanometers using dry batteries, its battery life is poor, and at the same time, it will also have a certain impact on environmental pollution. And because the total volume of the air pump and the solenoid valve is too large, it is impossible to make the terminal product miniaturized. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention prov...
