Embodiment Construction

[0019] The present invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present invention in a schematic manner, so it only shows the composition related to the present invention.

[0020] Such as figure 1 As shown, a micropump structure based on liquid metal at room temperature includes a channel 10, a first electrode 12, a second electrode 14 and a power generator 16, an open chamber 18 is arranged in the channel 10, and the open chamber 18 contains The liquid metal droplet 20 is used to limit the movement of the liquid metal droplet 20 through the setting of the open chamber 18, so as to maintain the relative position of the liquid metal droplet 20, and at the same time ensure that the liquid metal droplet 20 does not undergo large deformation, and the channel 10 Filled with electrolyte solution (not shown in the figu...

Abstract

The invention relates to a micropump structure based on liquid metal at room temperature, the micropump structure including a channel, a first electrode, a second electrode and a power generator. An open chamber is arranged in the channel, a liquid metal droplet is contained in the open chamber, an electrolyte solution is filled in the channel, one end of the first electrode and one end of the second electrode are in contact with the electrolyte solution, and the other end of the first electrode and the other end of the second electrode are connected with the power generator. The structure does not contain any mechanical moving parts, greatly reduces the local pressure loss caused by the micro pump structure itself in the fluid, and simultaneously avoids the heat loss caused by the heatingof the parts, at the same time, the structure can generate a larger flow rate under relatively small power consumption, the structure is simple and efficient, and the pumping effect is greatly improved.

Description

technical field [0001] The invention relates to the field of microfluidic technology, in particular to a micropump structure based on liquid metal at room temperature. Background technique [0002] Micropump technology is one of the core technologies in the field of microfluidics, and it is the mainstream direction of future research. However, at this stage, the micropump and its integrated technology are limited by their limited flow and relatively high power consumption, and their development is slow. This is largely due to the fact that it requires complex moving parts to work, which also poses a burden to maintenance. Great inconvenience. Contents of the invention [0003] The invention overcomes the deficiencies of the prior art and provides a micropump structure based on liquid metal at room temperature with simple structure. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: a micropump structure based on liq...
