Description
Technical field
The present invention protects micro air pump, is particularly suited for the flat formula micro air pump of small-sized sphygmomanometer.
Background technology
The profile of the micro air pump used on Arm-cuff device currently on the market, great majority are all cylindric, and basic structure principle is by driven by motor eccentric wheel, make support drive three air bags to do and compress/extensional motion, thus form exhaust/air-breathing.This structure uses the purpose of three air bags to be contemplated to increase amount of pressurization, because the amount of pressurization of Arm-cuff device is bigger.Existing a kind of the thinnest lighter with the most portable ultrathin type Arm-cuff device taking direction as the leading factor, limitation because of its size and shape, needing to realize the small size of used micro air pump on the premise of ensureing amount of pressurization, existing cylindric micro air pump can not meet this demand.
Summary of the invention
nullThe flat formula micro air pump that the present invention provides，Including electric machine assembly、Compression assembly and air chamber component，Electric machine assembly includes motor、Motor driving shaft and eccentric shaft，Compression assembly includes multiple piston and piston holder，Motor driving shaft is in transmission connection mutually with described eccentric shaft，Together with eccentric shaft is relatively fixed with piston holder，Piston holder forms socket with piston and coordinates，Air chamber component includes air chamber base、Umbrella one-way exhaust valve、Air bleeding valve support and valve，Piston seals with air chamber base joins merga pass breather check valve air-breathing，By the venthole on air bleeding valve support and umbrella one-way exhaust valve exhaust，The axis of multiple pistons of flat formula micro air pump is in one plane，There is the angle of inclination of 20～40 degree at the two ends of described piston holder and air bleeding valve support both with respect to its respective mid portion towards piston side，Wherein the preferred number of piston is 4，Angle of inclination is preferably 30 degree.
The present invention is ensureing amount of pressurization and on the premise of the micro air pump life-span, the profile of electronic sphygmomanometer micro air pump is being become thinner.
Accompanying drawing explanation
The sectional view of the flat formula micro air pump that Fig. 1 provides for the present invention.
Detailed description of the invention
Below according to specific embodiment, the present invention is described in detail.nullAs shown in Figure 1，This flat formula micro air pump，Including electric machine assembly、Compression assembly and air chamber component，Electric machine assembly includes motor 1 and motor driving shaft 2 and eccentric shaft 3，Compression assembly includes piston 4(piston 41、42、43、44 are referred to as piston 4) and piston holder 5，Motor driving shaft 2 is in transmission connection with eccentric shaft 3 phase，Together with eccentric shaft 3 is relatively fixed with piston holder 5，Piston holder 5 forms socket with piston 4 and coordinates，Air chamber component includes air chamber base 6、Umbrella one-way exhaust valve 7、Air bleeding valve support 8 and valve 9，Piston 4 seals with air chamber base 6 joins merga pass breather check valve 10 air-breathing，By the venthole 11 on air bleeding valve support 8、Umbrella one-way exhaust valve 7 and valve 9 are vented，The axis of four pistons is in one plane，Four piston cross direction profiles，And coordinate on piston holder 5，The two ends of piston holder 5 and air bleeding valve support 8 all extend，The part of elongation has the angle of inclination of 20-40 degree both with respect to its respective mid portion towards piston side，The most preferably 30 degree.Four piston base are separately fixed on piston holder 5.When motor 1 and eccentric shaft 3 rotate, be relatively fixed with piston holder 5 because of eccentric shaft 3 together with, piston holder 5 forms socket with piston 4 and coordinates, and four pistons, along with the up and down motion of piston holder 5, compress two-by-two or stretch, the exhaust of formation micro air pump or air-breathing.Due to by piston 4 cross direction profiles, so in the case of not changing air inflow, the thickness making micro air pump is the most thinning, 8mm can be reached thick.Because the power of this flat formula micro air pump is driven by motor eccentric shaft turns, together with eccentric shaft 3 is relatively fixed with piston holder 5, four pistons compress two-by-two along with the up and down motion of piston holder 5 or stretch, i.e. piston 41 and the equidirectional operation of piston 42, piston 43 and the equidirectional operation of piston 44, and piston 41 is contrary with piston 43 traffic direction.If piston holder 5 top is in one plane, i.e. in one plane, then piston 41 and piston 44 at two ends are longer relative to piston 42 and piston 43 tensile elongation in running, and piston 4 can be caused to harden and lifetime for the upper plane of four pistons.The structure that the present invention uses, the two ends of piston holder 5 and air bleeding valve support 8 the most all extend, elongation part relative to its respective mid portion at the angle of inclination having 20～40 degree towards piston 4 side, there is the angle of inclination of 20～40 degree of degree at the i.e. two ends of piston holder 5 and air bleeding valve support 8 both with respect to its respective mid portion towards piston side, and optimized angle is 30 degree.Piston 41 and piston 44 are positioned at the two ends of above-mentioned elongation, therefore suitable with piston 42 and piston 43 tensile elongation in running, thus are not result in piston hardening and lifetime, it is possible to extend the bulk life time of the flat formula micro air pump that the present invention provides.
The realization of this scheme, can make the light and handy degree of micro air pump even Arm-cuff device and portable degree more preferable, adapt to the fashion trend on market, makes client more easily go experience and use Arm-cuff device product.
