Abstract
The invention discloses a life monitoring device which comprises a compressor. A diaphragm pump serves as the compressor. The compressor comprises a diaphragm assembly, a drive assembly and a shell. The diaphragm assembly and the drive assembly are arranged in the shell. The diaphragm assembly comprises a cavity, a first valve block, a diaphragm and a second valve block. The first valve block, the diaphragm and the second valve block are sequentially arranged in the cavity. The life monitoring device is characterized in that the drive assembly comprises a connecting rod, a crank arm and a motor, one end of the connecting rod is connected with the diaphragm, the other end of the connecting rod is hinged to one end of the crank arm, the other end of the crank arm is connected to a motor shaft of the motor, and the crank arm has the degree of freedom for the crank arm to freely rotate in the plane perpendicular to the axis of the motor shaft. The microminiaturization of the medical compressor is achieved, and meanwhile the service life of the medical compressor is prolonged and noise of the medical compressor is reduced.
Description
Technical field
The present invention relates to a kind of monitoring device, be specifically related to a kind of life monitoring device.
Background technique
At present in compressor or the field of vacuum of medical industry, product category is a lot, and volume span is also very large, various aspects of performance requires very high, and the micro-compressor such as on life monitoring device is all the time large by noise, life-span is short, and bulky problem perplexed.Along with improving constantly of medical technology, impel modality constantly past microminiaturization, the long lifetime, high stable, the future development of low noise, and these demands just commercially display rapidly.
Summary of the invention
Goal of the invention of the present invention is to provide that a kind of noise is low, and volume is little, the microminiature compressor for life monitoring device that the life-span is long.
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of life monitoring device, comprise compressor, described compressor is diaphragm pump, comprise septum assembly, driven unit and housing, described septum assembly and driven unit are arranged in described housing, wherein, described septum assembly comprises cavity, the first valve block, diaphragm and the second valve block, described first valve block, diaphragm and the second valve block are set in turn in described cavity, and described driven unit comprises connecting rod, cranks arm and motor; One end of described connecting rod connects described diaphragm; The one end of cranking arm described in the other end of described connecting rod is articulated with; The motor shaft that the described the other end of cranking arm is connected to described motor has and transports dynamic degrees of freedom at the plane internal rotation vertical with described motor shaft axis.
In technique scheme, described valve block is floating type valve block.
In technique scheme, described diaphragm is quality of rubber materials.
Because technique scheme is used, the present invention compared with prior art has following advantages: diaphragm pump adopts curved arm rod mechanism, the motion of band dynamic diaphragm, and then the corresponding opening and closing of band moving valve plate, produces the gas circuit of single stable; Adopt open type housing, not only simplify assembly technology, and control the volume of complete machine; Adopt floating type valve block, improve the stability of product, and reduce the volume of cavity chamber.
Accompanying drawing explanation
Fig. 1 is structure front view of the present invention;
Fig. 2 is structure plan view of the present invention;
Fig. 3 is structure left view of the present invention.
Wherein, 1. the floating type valve block of housing 21. cavity 22. first 23. second floating type valve block 24. round rubber diaphragm 31. connecting rod 32. is cranked arm 33. motor shaft 34. motors.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment one
See Fig. 1-Fig. 3, as shown in legend wherein: a kind of life monitoring device, comprise three side open type housings 1 and the septum assembly be located in described three side open type housings 1 and a driven unit, described septum assembly comprises a cavity 21, be located at the second floating type valve block 23 of first of described chamber inlet the floating type valve block 22 and outlet and be fixed on a round rubber diaphragm 24 at position, described cavity stage casing, and described driven unit comprises 31, one, a connecting rod and to crank arm 32 and a motor 34; The free end of described connecting rod 31 connects described circular round rubber diaphragm 24; Crank arm described in the other end of described connecting rod 31 is articulated with 32 one end; The motor shaft 33 that the described the other end of cranking arm 32 is connected to described motor 34 is transported dynamic at the plane internal rotation with described motor shaft 33 axes normal.
Introduce working principle of the present invention below.
After opening motor 34, motor shaft 33 starts to rotate, drive to crank arm simultaneously and 32 to move in a circle in the plane vertical with motor shaft 33, and then drivening rod 31 carries out the motion of similar elliptical orbit, the round rubber diaphragm 24 be connected on connecting rod 31 also moves back and forth, when round rubber diaphragm 24 outwards moves, first floating type valve block 22 side-to-side movement discharges space, and the closely sealed cavity 21 of the floating type valve block in outlet port about 23, air is inhaled within cavity 21 thereupon, when round rubber diaphragm 24 moves inwards, the closely sealed cavity 21 of first floating type valve block about 22, and the second floating type valve block 23 side-to-side movement discharges space, air is spued outside cavity 21 thereupon.
Embodiment two
All the other are identical with described embodiment one, and difference is, the diaphragm being fixed on cavity stage casing opening part is oval elastomer diaphragm.
Claims (3)
