Abstract
The utility model discloses an ultra-small type compressor for a life monitor. The ultra-small type compressor is a membrane pump, and comprises a shell, a membrane assembly and a driving mechanism; the membrane pump assembly and the driving mechanism are fixedly arranged in the shell; the membrane assembly comprises a cavity, valve sheets arranged at an inlet and an outlet of the cavity, and a membrane sheet arranged on the middle section of the cavity; and the driving mechanism comprises a connecting rod, a crank and a motor. The ultra miniaturization of the medical compressor is realized. Meanwhile, the service life of the medical compressor is prolonged, and the noise of the medical compressor is reduced.
Description
Technical field
The utility model relates to a kind of microminiature compressor, particularly relates to a kind of microminiature compressor that is used for life monitor.
Background technique
In the compressor or the field of vacuum of medical industry, product category is a lot of at present, and the volume span is also very big, and various aspects of performance requires very high, and is big by noise all the time such as the micro-compressor that is used on the life monitor, and the life-span is short, and bulky problem perplexs.Along with improving constantly of medical skill, impelling modality constantly toward microminiaturized, the long lifetime, high stable, the direction of low noise develops, and these demands display on market just rapidly.
The model utility content
The purpose of the utility model is, provides a kind of noise low, and volume is little, the microminiature compressor that is used for life monitor that the life-span is long.
For realizing above-mentioned purpose; The utility model provides a kind of microminiature compressor that is used for life monitor; Be a diaphragm pump, comprise casing and the diaphragm pump of being located in the said casing, said diaphragm pump comprises septum assembly and driving mechanism; The diaphragm that said septum assembly comprises cavity, is located at the valve block of said cavity entrance and exit and is fixed in said cavity stage casing opening part, said driving mechanism comprise connecting rod, crank arm and motor; The free end of said connecting rod connects said diaphragm; The other end of said connecting rod is articulated in a said end of cranking arm; The said the other end of cranking arm be connected on the motor shaft of said motor and with the plane of said motor shaft axis normal in rotatablely move.
Preferably, said valve block is floating type valve block.
Preferably, said diaphragm is the rubber material.
Preferably, said casing is open casing.
Preferably, said open casing is the open open casings of three sides.
Adopt the beneficial effect of above technological scheme to be: diaphragm pump adopts curved arm rod mechanism, drives the motion of diaphragm, and then drives the corresponding opening and closing of valve block, produces the gas circuit of single stable; Adopt open casing, not only simplified assembly technology, and controlled the volume of complete machine; Adopt floating type valve block, improved the stability of product, and dwindled the volume of cavity chamber.
Description of drawings
Fig. 1 is the structure front view of the utility model;
Fig. 2 is the structure plan view of the utility model;
Fig. 3 is the structure left view of the utility model.
Wherein, 1. floating type valve block 24. round rubber diaphragms 31. connecting rods 32. of floating type valve block 23. outlets of the open casing of three sides 21. cavitys 22. inlets 33. motor shafts, 34. motors of cranking arm.
Embodiment
Specify the preferred implementation of the utility model below in conjunction with accompanying drawing.
Referring to Fig. 1; Fig. 2 and Fig. 3; A kind of microminiature compressor that is used for life monitor; Be a diaphragm pump, comprise one three an open casing 1 of side and a diaphragm pump of being located in the open casing 1 of said three sides, said diaphragm pump comprises septum assembly and a driving mechanism; Said septum assembly comprises a cavity 21, be located at the floating type valve block 22 of inlet and the floating type valve block 23 of outlet of outlet and a round rubber diaphragm 24 that is fixed in position, said cavity stage casing of said cavity inlet, and said driving mechanism comprises a connecting rod 31, the 32 and motors 34 of cranking arm; The free end of said connecting rod 31 connects said circular round rubber diaphragm 24; The other end of said connecting rod 31 is articulated in said 32 the end of cranking arm; Said 32 the other end of cranking arm be connected on the motor shaft 33 of said motor 34 and with the plane of said motor shaft 33 axis normal in rotatablely move.
Introduce the working principle of the utility model below.
After opening motor 34, motor shaft 33 begins to rotate, and driving simultaneously cranks arm 32 moves 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 that is connected on the connecting rod 31 also moves back and forth, and when round rubber diaphragm 24 outwards moved, floating type valve block 22 side-to-side movements that enter the mouth discharged the space; And floating type valve block 23 left and right sides driving fit cavitys 21 in outlet port; Air is inhaled within the cavity 21 thereupon, and when round rubber diaphragm 24 moved inwards, floating type valve block 22 left and right sides driving fit cavitys 21 entered the mouth; Discharge the space and export floating type valve block 23 side-to-side movements, air is spued outside the cavity 21 thereupon.
Embodiment 2
All the other are identical with said embodiment 1, and difference is that the diaphragm that is fixed in cavity stage casing opening part is oval elastomer diaphragm.
Adopt the beneficial effect of above technological scheme to be: diaphragm pump adopts curved arm rod mechanism, drives the motion of diaphragm, and then drives the corresponding opening and closing of valve block, produces the gas circuit of single stable; Adopt open casing, not only simplified assembly technology, and controlled the volume of complete machine; Adopt floating type valve block, improved the stability of product, and dwindled the volume of cavity chamber.
Above-described only is the preferred implementation of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; Can also make some distortion and improvement, these all belong to the protection domain of the utility model.
Claims (5)
