[0039] The liquid inlet control valve 204 and the first control valve 316 are both electrically controlled one-way valves, and a controller is arranged outside. The pH detection element 202 transmits the signal of the detected pH value to the controller, and the controller controls the opening and closing of the liquid inlet control valve 204, the first control valve 316 and the second control valve 319, wherein the controller controls the opening and closing of the corresponding first control valve 316 and the second control valve 319 according to the pH value; in this embodiment, the first liquid storage grid 317 stores alkalinity regulating liquid, and the second liquid storage grid 325 stores acidity regulating liquid; by controlling the on and off of the third electromagnet 106, the inertial motion in the fermentation liquid is utilized, causing the two first motion sliders 104 in the second autonomous sliding ring 102 to continuously move and collide, and the ball 101 can enter the fermentation liquid.

[0042] Example 2

[0043] Reference Figures 5 to 9, which is the second embodiment of the present invention, provides a microfluidic device for detecting and maintaining fermented wine indicators. The difference from the first embodiment 1 is that when the regulating liquid in the liquid storage grid is discharged outward, the refluxed fermentation liquid will not flow back into the liquid outlet regulating tube 318.

[0044] Specifically, two groups of drainage components 300 corresponding to the first liquid storage grid 317 and the second liquid storage grid 325 are included. The drainage component 300 includes a drainage pipe 302 connected to the outer end of the sphere 101. The end of the drainage pipe 302 away from the sphere 101 has a liquid outlet 302a. The drainage pipe 302 is provided with at least one liquid outlet channel 302b that is always connected to the end of the corresponding liquid outlet regulating pipe 318. In this embodiment, two groups of liquid outlet channels 302b are provided on one drainage pipe 302. The two groups of liquid outlet channels 302b are symmetrically arranged about the center of the drainage pipe 302. The drainage pipe 302 at the end of the liquid outlet channel 302b away from the sphere 101 is provided with a liquid control channel 302c. An isolation seat 303 is fixedly connected to the discharge pipe 302 at the control liquid flow channel 302c, and a regulating valve body 305 moving toward the direction of the periphery of the liquid outlet 302a is connected to the isolation seat 303. A plurality of discharge holes 303a are arranged on the isolation seat 303. The regulating valve body 305 includes a moving part 305b, and a plurality of sealing parts 305a corresponding to the discharge holes 303a are arranged on the moving part 305b. When the moving part 305b contacts the liquid outlet seat, the sealing part 305a is in the discharge hole 303a, and the liquid outlet flow channel 302b is isolated from the liquid outlet 302a under the action of the sealing part 305a; when the sealing part 305a moves toward the direction of the liquid outlet 302a and leaves the discharge seat, the sealing part 305a is in the discharge hole 303a. When the liquid hole 303a is formed, the liquid outlet channel 302b is connected to the liquid outlet port 302a through the liquid outlet hole 303a, and the liquid control seat 312 is fixedly connected to the liquid outlet pipe 302 at the liquid outlet channel 302b. Two outer baffles 314 and inner baffles 313 are slidably connected to the liquid control seat 312. The liquid control seat 312 is provided with a liquid control hole 312a that can be connected to the liquid outlet channel 302b and the liquid control channel 302c. The outer baffle 314 and the inner baffle 313 can independently seal the liquid control hole 312a. When viewed in the axial direction, the inner baffle 313 is between the outer baffle 314 and the sphere 101, and one end of the inner baffle 313 is arranged relative to the direction where the center of the liquid outlet pipe 302 is located. A moving rod 309 is fixedly connected, and the moving rod 309 and the moving part 305b are fixedly connected. At least one first return spring 315 is fixedly connected to one end of the outer baffle plate 314 facing the direction of the central axis of the discharge pipe 302. In this embodiment, two first return springs 315 are fixedly connected to the outer baffle plate 314, and one end of the first return spring 315 away from the outer baffle plate 314 is fixedly connected to the discharge pipe 302; in the initial state, the sealing part 305a is in the discharge hole 303a, and the outer baffle plate 314 and the inner baffle plate 313 do not cover the liquid control hole 312a. When the sealing part 305a leaves the discharge hole 303a and reaches a suitable position, the inner baffle plate 313 blocks the liquid control hole 312a.

[0045] When the pH value of the fermentation liquid needs to be adjusted, the corresponding third control valve 323, the first control valve 316, and the second control valve 319 are controlled to open, and the fan 321 is activated. The fan 321 outputs high-pressure gas, and the high-pressure gas pushes the regulating liquid to be transported in the direction of the liquid outlet regulating pipe 318. The regulating liquid output from the liquid outlet regulating pipe 318 enters the liquid outlet flow channel 302b. The pressure in the liquid outlet flow channel 302b is greater than the hydraulic pressure at the liquid outlet 302a, and the moving part 305b is pushed to move in the direction of the central axis of the drainage pipe 302. The regulating liquid is discharged from the drainage pipe 302 through the liquid outlet 302a. After the drainage is completed, the fan 321 stops operating. The hydraulic pressure in the tank body is greater than the pressure in the liquid outlet flow channel 302b. The moving part 305b moves toward the direction of the isolation seat 303. The moving part 305b contacts the isolation seat 303 again, and the sealing part 305a is inserted into the drainage hole 303a to achieve controllable drainage.

[0046] Specifically, a sliding plate 306 is slidably connected to the drain pipe 302, and the end of the sliding plate 306 away from the sealing portion 305a is fixedly connected to the second return spring, and the end of the second return spring away from the sliding plate 306 is fixedly connected to the drain pipe 302, the sliding plate 306 is fixedly connected to the moving portion 305b, and the end of the sliding plate 306 away from the moving portion 305b in the axial direction is fixedly connected to the connecting bracket 307, and the connecting bracket 307 is fixedly connected to the first electromagnet, and the connecting bracket 307 is fixedly connected to the moving rod 309, and the outer baffle 314 faces the drain pipe. One end of 302 in the direction of the central axis is also fixedly connected to a sliding rod 311, and the end of the sliding rod 311 away from the outer baffle plate 314 is fixedly connected to a second electromagnet 308 arranged in the axial direction relative to the first electromagnet. When the sealing part 305a leaves the drainage hole 303a to a suitable position, the first electromagnet and the second electromagnet 308 are actuated, and the sliding rod 311 and the connecting bracket 307 are connected together. When the sealing part 305a leaves the drainage hole 303a to a suitable position and is reinserted into the drainage hole 303a, the outer baffle plate 314 covers the liquid control hole 312a.

[0047] The second return spring is in a compressed state. When the high-pressure gas pushes the regulating liquid to open the sealing part 305a, the moving part 305b drives the connecting bracket 307 to move through the sliding plate 306, and the second return spring is further compressed. When the sealing part 305a leaves the isolation seat 303 to a suitable position, the inner baffle plate 313 covers the liquid control hole 312a, controls the first electromagnet and the second electromagnet 308 to act, and the connecting bracket 307 is connected to the outer baffle plate 314 through the sliding rod 311. The fan 321 stops moving, and the hydraulic pressure outside the discharge pipe 302 is greater than the pressure at the liquid outlet channel 302b. The moving part 305b moves in the opposite direction under the action of the external hydraulic pressure and the second return spring, and at the same time drives the outer baffle plate 314 to move toward the direction of the liquid control hole 312a. The outer baffle plate 314 covers the liquid control hole 312a. When the moving part 305b contacts the isolation seat 303 again, the liquid outlet channel 302b and the liquid outlet 302a are separated again.

[0048] Specifically, a recovery box 301 corresponding to the liquid outlet flow channel 302b is fixedly connected to the outside of the liquid discharge pipe 302, and a recovery flow channel 301b is opened on the recovery box 301. A sealing flow channel 301c connected to the liquid outlet flow channel 302b is opened at one end of the recovery box 301 relative to the liquid discharge pipe 302. The sealing flow channel 301c is arranged between the outer baffle plate 314 and the liquid control seat 312. One end of the recovery flow channel 301b is connected to one end of the sealing flow channel 301c. The end of the recovery box 301 relative to the spherical body 101 is provided with a device for storing liquid that flows back through the liquid outlet 302a, the liquid discharge flow channel and the liquid outlet flow channel 302b in sequence. One end of the recovery flow channel 301b is connected to the recovery flow channel 301c. The cavity is connected, the other end of the recovery channel 301b is connected to the sealing channel 301c, and a recovery liquid rod 304 is movably connected in the recovery channel 301b.

In the initial state, the recovery liquid sealing plate 310 blocks the sealing channel 301c; when the inner baffle plate 313 covers the drainage hole 303a, the recovery liquid sealing plate 310 leaves the sealing channel 301c, so that the sealing channel 301c and the recovery channel 301b are connected.

[0049] When the connecting bracket 307 drives the outer baffle plate 314 to move via the sliding rod 311, the outer baffle plate 314 drives the recovery liquid sealing plate 310 away from the sealing flow channel 301c via the recovery liquid rod 304, and a small amount of fermentation liquid entering the outlet flow channel 302b enters the recovery chamber 301a via the sealing flow channel 301c and the recovery flow channel 301b. When the sealing portion 305a is pressed against the liquid control seat 312, the first electromagnet and the second electromagnet 308 are controlled to be disconnected, and the outer baffle plate 314 moves toward the direction of the central axis of the discharge pipe 302 under the action of the first return spring 315, leaving the liquid control hole 312a, and the recovery liquid sealing plate 310 is inserted into the sealing flow channel 301c again, so that the recovery flow channel 301b and the outlet flow channel 302b are isolated, which is convenient for the discharge of the regulating liquid later and further realizes the pH value adjustment at other positions.

[0050] In addition, an electrically controlled one-way valve (not shown in this application, which is prior art) may be installed on the recovery box 301 at the bottom of the recovery chamber 301a, and the electrically controlled one-way valve may be opened by timing control to discharge the fermented wine in the recovery chamber 301a into the tank.

[0051] Each control valve in the present application is prior art, and the connection between it and the corresponding pipeline is also prior art, and the connection method and specific structure thereof are not described in detail in the present application.

[0054] Specifically, the sphere 101 is connected to a first liquid replenishing tube 327 and a second liquid replenishing tube 328 for replenishing the regulating liquid. The inner ends of the first liquid replenishing tube 327 and the second liquid replenishing tube 328 are fixedly connected to the first liquid storage grid 317 and the second liquid storage grid 325 respectively. The first liquid replenishing tube 327 and the second liquid replenishing tube 328 are respectively connected to different liquid pumps outside the tank body via two hoses at one end away from the first liquid storage grid 317 and the second liquid storage grid 325 respectively. The liquid pump is connected to the liquid storage tank. The hose is not drawn. The hose and the liquid storage tank are both existing technologies. When liquid replenishment is needed, the liquid pump is activated to pump the regulating liquid into the corresponding liquid storage grid.
