Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
A liquid circuit switching mechanism according to an embodiment of the present invention is described below with reference to fig. 1 to 4.
As shown in fig. 1 to 4, the liquid circuit switching mechanism includes a liquid circuit switching assembly. The liquid circuit switch 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 to 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 are jointly formed into 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 break the circuit.
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 are configured as one 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 rest state is as shown in fig. 1, and the condition of the liquid circuit switch in the on state is that the elastic membrane 5 deforms under the action of the negative pressure of the fluid to enable the liquid circuit channel 2 to circulate, and the circuit is switched from the state of fig. 1 to the state of fig. 2. The condition of being in the closed state again is that the elastic membrane 5 resumes deformation under the withdrawal of the fluid negative pressure to interrupt the liquid circuit channel 2 and the circuit is broken, i.e. the state of fig. 2 is restored to the state of fig. 1.
If the liquid circuit switch is a normally open switch, the static state is as shown in fig. 2, and the condition of the liquid circuit switch in the closed state is that the elastic membrane 5 deforms under the action of the positive pressure of the fluid to block the liquid circuit channel 2, and the circuit is broken, namely, the state of the liquid circuit switch is switched from the state of fig. 2 to the state of fig. 1. The condition of the elastic membrane 5 in the open state again is that the elastic membrane is deformed under the withdrawal of the positive pressure of the fluid, so that the liquid circuit channel 2 circulates, and the circuit is conducted, namely, the state of the liquid circuit channel is recovered from the state of fig. 1 to the state of fig. 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 elastic films 5, and each elastic film 5 and the fluid channel 4 are configured into a liquid circuit switch, and the liquid circuit switch can respectively control the conduction or 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 on 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 is as shown in fig. 3, and the condition of the two liquid circuit switches in the open state is that the elastic membrane 5 deforms under the action of the negative pressure of the fluid to enable the two liquid circuit channels 2 to circulate simultaneously, and the circuit is switched on, 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 resumes deformation under the withdrawal of the fluid negative pressure to interrupt the two liquid circuit channels 2, and the circuit is broken, i.e. the state is restored from the state of fig. 4 to the state of fig. 3.
If the two liquid circuit switches are normally open switches, the static state is as shown in fig. 4, and the condition of the two liquid circuit switches in the closed state is that the elastic membrane 5 deforms under the action of the positive pressure of the fluid to respectively block the two liquid circuit channels 2, and the circuit is broken, namely, the state of fig. 4 is switched to the state of fig. 3. The condition of the elastic membrane 5 in the open state again is that the elastic membrane is deformed under the withdrawal of the positive pressure of the fluid, so that the two liquid circuit channels 2 circulate, and the circuit is conducted, namely, the state of the elastic membrane is recovered from the state of fig. 3 to the state of fig. 4.
According to the liquid circuit switch provided by the embodiment of the invention, the elastic membrane is caused to deform under the action of the fluid, so that the liquid circuit channel is controlled to be turned off or circulated, and the working state of the liquid electronic circuit is 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 one embodiment of the present invention, the liquid circuit switching mechanism further includes a driving device, which is connected to the fluid channel 4, and driven by the driving device, the fluid triggers the elastic membrane 5 to deform, so as to block the liquid circuit channel 2 or connect 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 negative pressure can be generated by setting the 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, so that the liquid circuit channel 2 is communicated.
When the driving device is a thermal driving device, the fluid in the fluid channel 4 is heated, so that the expansion of the fluid causes the elastic membrane 5 to deform, and the liquid circuit channel 2 is blocked. When the fluid temperature decreases, the elastic membrane 5 resets and the liquid circuit channel 2 communicates.
Further, in one embodiment of the present invention, the pressure driving device may alternatively be a pressure pump, a syringe pump, a centrifugal sampler, an electroosmotic pump, or the like.
Further, in one embodiment of the present invention, the thermal drive may alternatively be an electromagnetic heater, an infrared heater, a resistive heater, or the like.
It should be noted that: the driving device may be any other driving device, and the driving device may be only capable of causing 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 alternatively be any one of square, arch, semicircle, or trapezoid.
In one embodiment of the present invention, the cross-sectional shape of the fluid passage 4 may alternatively be any one of an arch, a semicircle, or a polygon.

Specifically, the gallium-based alloy may be gallium indium alloy, gallium tin alloy, gallium indium zinc alloy, gallium indium tin zinc alloy, or the like.
In one embodiment of the invention, alternatively, the elastic membrane 5 may be: one or two of PDMS (dimethyl siloxane) film, PMMA (polymethyl methacrylate) film, PVC (polyvinyl chloride) film, PE (polyethylene) film, PP (polypropylene) film, PET (polyethylene terephthalate) film, PC (polycarbonate) film or other deformable plastic film.
In one embodiment of the present invention, the fluid filled in the fluid channel 4 may be optionally at least one of nitrogen, oxygen, carbon dioxide, air, water or other fluid that may trigger the deformation of the elastic membrane 5.
The embodiment of the invention also provides a multi-layer parallel liquid circuit switch, in particular to a multi-layer parallel liquid circuit switch which comprises a plurality of parallel liquid circuit switch components. That is, the liquid circuit switch with multiple parallel layers comprises a plurality of liquid circuit layers 1 and pressure control layers 3 which are sequentially overlapped to form a plurality of liquid circuit switches, and through regulating and controlling the fluid in each fluid channel 4, the working states of the liquid circuit switches in different layers can be regulated and controlled simultaneously, so that the liquid circuits in different layers are in various working states.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
