Embodiment 1

[0031] see Figure 1-Figure 3 As shown, this embodiment discloses a pneumatic opening and closing system 10 . The pneumatic opening and closing system 10 includes a housing and a closing device 200 .

[0032] In this embodiment, the housing is in the shape of a cuboid. It is not difficult to understand that the housing may also be in other regular or irregular shapes. The cross-section of the housing along the long axis is square, and the two square surfaces form the bottom surface and the upper surface of the housing. The housing has a cavity and a plurality of fluid channels 123 . The bottom surface of the cavity is in the shape of a smooth curved surface.

[0033] There are multiple fluid channels 123, two in this embodiment. One ends of the two fluid passages 123 are both open to the bottom of the cavity, and the other ends are both open to the outer wall of the casing. In this embodiment, two fluid passages 123 are provided on the housing, and one end of the fluid pa...

Embodiment 2

[0046] This embodiment discloses a linkage opening and closing system.

[0047] In this embodiment, multiple pneumatic opening and closing systems 10 involved in Embodiment 1 can be combined to form a linked opening and closing system.

[0048] The linkage opening and closing system further includes a sealing plug 300 on the basis of the pneumatic opening and closing system 10 of the first embodiment. Three fluid channels 123 are now provided on the housing. One ends of the three fluid passages 123 are all opened on the bottom of the cavity, and the other ends are respectively opened on three sides of the casing.

[0049] see figure 2 As shown, the middle part of the sealing plug 300 has a vent hole. A side groove 124 is provided on the side of the housing, and the fluid channel 123 opens in the side groove 124. The above-mentioned sealing plug 300 can be matched with the side groove 124, and when the sealing plug 300 is located in the side groove 124, through The air hol...

Embodiment 3

[0058] This embodiment discloses a linkage opening and closing system.

[0059] In this embodiment, for example, the three pneumatic opening and closing systems 10 involved in Embodiment 1 can be combined to form a linked opening and closing system.

[0060] The linkage opening and closing system further includes a sealing plug 300 on the basis of the pneumatic opening and closing system 10 of the first embodiment. In this case, two fluid channels 123 are provided on the housing. One ends of the two fluid passages 123 are both opened on the bottom surface of the cavity, and the other ends are respectively opened on two opposite sides of the housing.

[0061] The middle part of the sealing plug 300 has a vent hole. A side groove 124 is provided on the side of the housing, and the fluid channel 123 opens in the side groove 124. The above-mentioned sealing plug 300 can be matched with the side groove 124, and when the sealing plug 300 is located in the side groove 124, through ...

Abstract

The invention discloses a linkage opening and closing system and a linkage opening and closing method thereof. The linkage opening and closing system comprises a plurality of pneumatic opening and closing systems which are provided with shells and closing devices. The shells are provided with cavities and a plurality of fluid channels. One ends of the fluid channels are provided with openings in the bottom faces of the cavities. The other ends of the fluid channels are provided with openings in the outer walls of the shells. The closing devices are provided with supporting parts and elastic cap hoods. The supporting parts are located in the cavities. The bottoms of the supporting parts are covered with the elastic cap hoods. When the elastic cap hoods are in the natural state, first cavities are formed in the inner walls of the elastic cap hoods and the bottom faces of the supporting parts, and the outer walls of the elastic cap hoods make contact with the bottom faces of the cavities to form second cavities; and air inlet channels penetrate the supporting parts, one ends of the air inlet channels are provided with openings in the bottom faces of the supporting parts, and the other ends of the air inlet channels are provided with openings used for being communicated with an air inlet source. The pneumatic opening and closing systems are communicated in series or in parallel through the openings in the outer walls of the shells. The linkage opening and closing system is accurate in control and compact in structure.

Description

technical field [0001] The invention relates to the field of bioengineering, in particular to a linkage opening and closing system and a linkage opening and closing method thereof. Background technique [0002] In scientific research fields such as bioengineering, it is necessary to use some miniaturized and automated laboratory devices, such as some processes including liquid storage, liquid transmission, or switching between different liquid channels. In the process of liquid storage, liquid transmission or switching between different liquid channels, valves are often used to control the amount required for liquid storage, liquid transmission or switching between different liquid channels. If the amount of liquid is very small, it is difficult for traditional valves to achieve precise control during the control process. Contents of the invention [0003] Based on this, it is necessary to provide a linkage opening and closing system with accurate control. [0004] A lin...
