A liquid circuit switching mechanism according to an embodiment of the present invention will be described with reference to fig. 1 to 4.
As shown in fig. 1-4, the liquid circuit switching mechanism includes a liquid circuit switching assembly. The liquid circuit switching assembly includes: a liquid circuit layer 1, a pressure control layer 3 and an elastic membrane 5. The liquid circuit layer 1 is formed with a liquid circuit channel 2, and the liquid circuit channel 2 is filled with a conductive liquid. The pressure control layer 3 is arranged opposite the liquid circuit channel 2. Specifically, when the liquid circuit layer 1 is formed with one liquid circuit channel 2, the pressure control layer 3 is disposed below the liquid circuit channel 2; when the liquid circuit layer 1 is formed with two liquid circuit channels 2, the pressure control layer 3 is disposed in the middle of the two liquid circuit channels 2.
Further, a fluid passage 4 is formed on the pressure control layer 3, and an elastic membrane 5 is provided on the fluid passage 4. Wherein the fluid channel 4 and the elastic membrane 5 together form a liquid circuit switch, and the working principle of the liquid circuit switch is as follows: under the action of the fluid in the fluid channel 4, the elastic membrane 5 deforms to block the liquid circuit channel 2, and the circuit is broken.
As shown in fig. 1 and 2, when the liquid circuit layer 1 forms only one liquid circuit channel 2, the fluid channel 4 and the elastic membrane 5 form a liquid circuit switch. Specifically, as shown in fig. 1, the liquid circuit switch is in an off state. As shown in fig. 2, the liquid circuit switch is in an on state. The liquid circuit switch comprises a normally open switch and a normally closed switch;
if the liquid circuit switch is a normally closed switch, its static state is as shown in fig. 1, and its open state is a condition that the elastic membrane 5 deforms under the action of the fluid negative pressure to make the liquid circuit channel 2 flow, so that the circuit is turned on, i.e. the state in fig. 1 is switched to the state in fig. 2. The condition of being in the closed state again is that the elastic membrane 5 recovers deformation under the withdrawal of the fluid negative pressure to interrupt the liquid circuit channel 2, and the circuit is broken, namely, the state of fig. 2 is recovered to the state of fig. 1.
If the liquid circuit switch is a normally open switch, its static state is as shown in fig. 2, and its closed state is a condition that the elastic membrane 5 is deformed under the action of the positive pressure of the fluid to block the liquid circuit channel 2, and the circuit is broken, i.e. the state in fig. 2 is switched to the state in fig. 1. The condition of being in the open state again is that the elastic membrane 5 recovers deformation under the withdrawal of the positive pressure of the fluid, so that the liquid circuit channel 2 is communicated, and the circuit is conducted, namely the state of the figure 1 is recovered to the state of the figure 2.
As shown in fig. 3 and 4, when the liquid circuit layer 1 is formed with two liquid circuit channels 2, the fluid channel 4 is located in the middle of the two liquid circuit channels 2, the upper and lower surfaces of the fluid channel 4 are respectively provided with an elastic membrane 5, and each elastic membrane 5 and the fluid channel 4 are configured into a liquid circuit switch which can respectively control the conduction or the interruption of the two liquid circuit channels 2.
Specifically, as shown in FIG. 3, both liquid circuit switches are in an off state. As shown in fig. 4, both liquid circuit switches are in an open state. Similarly, the two liquid circuit switches also comprise a normally open switch and a normally closed switch;
if the two liquid circuit switches are normally closed switches, the static state of the two liquid circuit switches is as shown in fig. 3, and the condition that the two liquid circuit switches are in the open state is that the elastic membrane 5 deforms under the action of the fluid negative pressure to enable the two liquid circuit channels 2 to simultaneously flow, so that the circuit is conducted, namely, the state of fig. 3 is switched to the state of fig. 4. The condition of being in the closed state again is that the elastic membrane 5 recovers deformation under the withdrawal of the fluid negative pressure, so that the two liquid circuit channels 2 are interrupted, and the circuit is broken, namely the state of fig. 4 is recovered to the state of fig. 3.
If the two liquid circuit switches are normally open switches, the rest state is as shown in fig. 4, and the condition of the closed state is that the elastic membrane 5 is deformed under the action of the positive pressure of the fluid to respectively block the two liquid circuit channels 2, so that the circuit is broken, i.e. the state of fig. 4 is switched to the state of fig. 3. The condition of being in the open state again is that the elastic membrane 5 recovers deformation under the withdrawal of the positive fluid pressure, so that the two liquid circuit channels 2 are communicated, and the circuit is conducted, namely the state of the figure 3 is recovered to the state of the figure 4.
The liquid circuit switch provided by the embodiment of the invention enables the elastic membrane to deform under the action of the fluid, so that the channel of the liquid circuit is controlled to be closed or communicated, and the working state of the liquid electronic circuit is further changed. The design of the flexible switch not only reduces the generation of electric sparks when the switch is used, but also realizes the controllable and intelligent management of the flexible liquid electronic circuit.
In an embodiment of the present invention, the liquid circuit switch mechanism further includes a driving device, the driving device is connected to the fluid channel 4, and under the driving of the driving device, the fluid triggers the elastic membrane 5 to deform, so as to block the liquid circuit channel 2 or communicate with the liquid circuit channel 2.
Specifically, the driving device comprises a pressure driving device and a thermal driving device, when the driving device is the pressure driving device, the fluid in the fluid channel 4 can be pressurized or generate negative pressure by setting a pressure value, and when the fluid is pressurized, the fluid triggers the elastic membrane 5 to deform to block the liquid circuit channel 2. When the fluid generates negative pressure, the elastic membrane 5 is restored to the initial position under the action of the negative pressure, and the communication of the liquid circuit channel 2 is realized.
When the driving device is a thermal driving device, the fluid in the fluid channel 4 is heated, so that the fluid expands to drive the elastic membrane 5 to deform, and the liquid circuit channel 2 is blocked. When the temperature of the fluid is reduced, the elastic membrane 5 is reset, and the liquid circuit channel 2 is communicated.
Further, in one embodiment of the present invention, the pressure driving device may be a pressure pump, a syringe pump, a centrifugal sample injector, an electroosmotic pump, or the like.
Further, in one embodiment of the present invention, the thermal driving device may be an electromagnetic heater, an infrared heater, a resistance heater, or the like.
It should be noted that: the drive means may be any other type of drive means which is only required to cause the fluid to act on the elastic membrane 5 to cause the elastic membrane 5 to deform.
In one embodiment of the present invention, the cross-sectional shape of the liquid circuit channel 2 may be any one of a square shape, an arch shape, a semicircular shape, and a trapezoidal shape.
In one embodiment of the present invention, the cross-sectional shape of the fluid passage 4 may be any one of an arch shape, a semicircular shape, or a polygonal shape.

Specifically, the gallium-based alloy may be a gallium-indium alloy, a gallium-tin alloy, a gallium-indium-zinc alloy, a gallium-indium-tin-zinc alloy, or the like.

In one embodiment of the present invention, the fluid filled in the fluid channel 4 may be at least one of nitrogen, oxygen, carbon dioxide, air, water or other fluid capable of triggering the deformation of the elastic membrane 5.
The embodiment of the invention also provides a multilayer parallel liquid circuit switch, and particularly, the multilayer parallel liquid circuit switch comprises a plurality of parallel liquid circuit switch components. That is, the multilayer parallel liquid circuit switch comprises a plurality of liquid circuit layers 1 and pressure control layers 3 which are sequentially overlapped, and a plurality of liquid circuit switches are constructed, and the working states of the liquid circuit switches on different layers can be regulated and controlled simultaneously by regulating and controlling the fluid in each fluid channel 4, so that the liquid circuits on different layers are in various working states.
