Contracting and expansion, when the first pump chamber P21 expands, the gas in the first inlet plenum P20 is first sucked into the first pump chamber P21, when
When being compressed in the first pump chamber P21, the gas in the first pump chamber P21 is discharged in first exhaust room.
Specific work process is as follows：So that the first barrier film pump housing 20 vacuumizes for the first space as an example, motor for double-ended drive 10
During work, one end D10 of output shaft drives the first eccentric driving part 204 to swing, and the first eccentric driving part 204 drives the again
One membrane compresses component 202 moves, and then causes the first pump chamber P21 alternate compressions and expansion, when the first pump chamber P21 expands,
Gas is entered in the first inlet plenum P20 by air inlet H20 in first space, and is sucked into from the first inlet plenum P20
In one pump chamber P21, when the first pump chamber P21 compresses, the gas in the first pump chamber P21 is extruded to first row air chamber again, finally,
It is expelled to from the first row gas port of the first pump head 203 in external environment condition, hereby it is achieved that being vacuumized to the first space.
In the present embodiment, drive the first membrane compresses component 202 right by the oscillating motion of the first eccentric driving part 204
First pump chamber P21 carries out alternate compression and expansion, realizes that gas is quickly flowed into from air inlet H20 and arranged from the first gas outlet H21
Go out, its is simple in construction, easy to assembly, and operating efficiency is high.
Reference picture 2 is to shown in Fig. 4, in one embodiment of the invention, the first membrane compresses component 202 include first every
The barrier film 2022 of film seat 2021 and first, wherein, the first barrier film seat 2021 is arranged on first motor base 201, and with it is described
First motor base 201 limits the first inlet plenum P20.
First barrier film 2022 is arranged on the first barrier film seat 2021, and first barrier film 2022 has at least three
Towards the first leather cup 2023 of the direction of the first motor base 201 depression, three first leather cups 2023 are around the output shaft
Circumferentially-spaced arrangement, first pump is each limited between first leather cup 2023 and first pump head 203
Room P21, and the bottom wall of each first leather cup 2023 is provided with the first valve block 2024, each first valve block 2024 allows institute
State corresponding to the gas flow in the first inlet plenum P20 in first leather cup 2023.
That is, at least three first leather cups 2023 are circumferentially arranged at intervals with the first barrier film 2022, in Fig. 4 examples
In, the first leather cup 2023 is three, and the bottom of each first leather cup 2023 sets first valve block 2024, first valve block
2024 can control the circulating direction of gas, i.e., when the first pump chamber P21 expands, gas in the first inlet plenum P20 can be by
It is sucked into the first pump chamber P21, and gas can not reversely flow into the first inlet plenum P20 in the first pump chamber P21, and first
When pump chamber P21 is compressed, the gas in the first pump chamber P21 can only be expelled in first exhaust room, without reversely flowing into the
One inlet plenum P20, and then enable the reliable and stable work of the first barrier film pump housing 20.
First eccentric driving part 204 is connected with first leather cup 2023, to drive first leather cup 2023 to move
The first pump chamber P21 is set to expand or compress.
That is, the first eccentric driving part 204 is to be connected to the output shaft of the first leather cup 2023 and motor for double-ended drive 10
One end D10 between, when output shaft drive the first eccentric driving part 204 wave when, first eccentric driving part 204 can
To drive the first leather cup 2023 flexible, and then cause the first pump chamber P21 expansions or compression.
In the present embodiment, at least three first leather cups 2023 are set on the first barrier film 2022, utilize the first eccentric drive
Part 204 drives at least three first leather cups 2023 to stretch in turn, and then make it that at least three first pump chamber P21 are alternated
Expansion and compression, and then continuous suction gas and discharge gas are realized, improve its operating efficiency.
Shown in reference picture 4, more specifically, in one embodiment of the invention, the first eccentric driving part 204 includes the
