In view of the defect of prior art vacuum pump, the present inventor develops a kind of vacuum pump overcoming above-mentioned defect, and this case produces thus.
Summary of the invention
The object of the present invention is to provide that a kind of compressing tablet is easy for installation, the better and vacuum pump that volume is less of degree of vacuum.
For reaching above-mentioned purpose, solution of the present invention is:
Vacuum pump, comprises motor, housing, cam, connecting rod, curved bar, bearing, air bag, umbrella shape one-way valve, compressing tablet, valve seat and top cover; Motor is installed in the housing, and cam is arranged in the rotating shaft of motor, and cam arranges eccentric opening; Connecting rod is placed in eccentric opening, and is connected with curved bar; The bottom of air bag is arranged on curved bar, and air bag is arranged on bearing, and support saddle frame is located on housing; Valve seat is arranged on bearing, valve seat is arranged inlet hole and air outlet hole, and inlet hole and air outlet hole are separated by the twigs of the chaste tree, and inlet hole is relative with air bag with the position of air outlet hole, and inlet hole is installed umbrella shape one-way valve, compressing tablet is pressed on air outlet hole; Top cover is arranged on valve seat, top cover is arranged suction port and air outlet, and inlet hole communicates with suction port formation gas-entered passageway, and air outlet hole communicates with air outlet formation outlet passageway.
Further, air outlet hole is set to two, arranges raised line between air outlet hole, grooving in the middle of compressing tablet, and raised line makes compressing tablet be pressed on two air outlet holes through groove.
Further, arrange concave arc in the twigs of the chaste tree two air outlet hole positions corresponding on raised line, compressing tablet arranges the convex arc corresponding with concave arc, and convex arc is placed in concave arc makes compressing tablet be pressed on two air outlet holes.
Further, air bag is set to symmetrical two, curved bar is arranged accordingly two jacks, and the bottom of air bag is inserted in jack and is fixed on curved bar.
Further, curved bar arranges central shaft hole, in axis hole, put into spring and ball successively, connecting rod one end is inserted in central shaft hole, and the other end inserts in the eccentric opening of cam.
Further, on curved bar, corresponding central shaft hole position arranges spherical projection, and bearing arranges the ball recess coordinated with spherical projection, and spherical projection is placed in ball recess.
Adopt after such scheme, the present invention arranges compressing tablet on air outlet hole, and compressing tablet is pressed on air outlet hole, replaces traditional on air outlet hole, installing umbrella shape one-way valve; Compared with prior art, it has the following advantages:
One, air outlet hole arranges compressing tablet, it is easy for installation, only need be pressed on air outlet hole by compressing tablet, can save a large amount of installation times in production assembly process, thus improves installation efficiency;
Two, air outlet hole arranges compressing tablet, air outlet hole is pushed down by compressing tablet, even if the impact of being expanded with heat and contract with cold, also can not affect the sealing between compressing tablet and air outlet hole, thus ensure that vacuum pump has better degree of vacuum;
Three, air outlet hole arranges compressing tablet, when vacuum pump need arrange two or more air outlet hole, only slightly need do to change to the shape of compressing tablet, a compressing tablet is used just can just to push down by all air outlet holes, its space occupied is little, reduce the volume of minipump, thus adaptation is used in relevant device better.
