At this time, the liquid inlet hole 14, the connecting hole 13, the second space 50 and the second liquid outlet hole 16 are connected.

[0074] Please also see Figure 7 and Figure 8 The driving member 30 is connected to the first movable member 23, and the driving member 30 is used to drive the first movable member 23 to move away from the groove bottom 113 of the first diverter groove 11 so that a first space 40 is formed between the end of the first movable member 23 and the groove bottom 113 of the first diverter groove 11, and drive the second sealing member 22 on the second movable member 25 to abut against the groove bottom 123 of the second diverter groove 12, so that the liquid inlet hole 14 is connected to the first liquid outlet hole 15 through the connecting hole 13 and the first space 40, or drive the first sealing member 21 on the first movable member 23 to abut against the groove bottom 113 of the first diverter groove 11, and drive the second movable member 25 away from the groove bottom 123 of the second diverter groove 12 so that a second space 50 is formed between the end of the second movable member 25 and the groove bottom 123 of the second diverter groove 12, so that the liquid inlet hole 14 is connected to the second liquid outlet hole 16 through the connecting hole 13 and the second space 50. In this embodiment, the driving member 30 can be a cylinder.

[0075] It can be understood that the first liquid outlet 15 is used to transport qualified liquid, such as clean liquid without bubbles, impurities, etc., and the second liquid outlet 16 is used to transport unqualified liquid, such as unclean liquid containing bubbles, impurities, etc., or the first liquid outlet 15 is used to transport unqualified liquid and the second liquid outlet 16 is used to transport qualified liquid. The liquid can be water, glue, etc.

[0076] The liquid separation device 100 provided in the embodiment of the present application can drive the first movable member 23 and the second movable member 25 to move in the first diverter groove 11 and the second diverter groove 12 respectively through the driving member 30, and then when the first movable member 23 is away from the groove bottom 113 of the first diverter groove 11 and the second movable member 25 abuts against the groove bottom 123 of the second diverter groove 12, the liquid inlet hole 14 is connected with the first liquid outlet hole 15 through the connecting hole 13. When the first movable member 23 abuts against the groove bottom 113 of the first diverter groove 11 and the second movable member 25 is away from the groove bottom 123 of the second diverter groove 12, the liquid inlet hole 14 is connected with the second liquid outlet hole 16 through the connecting hole 13. In this way, liquid can be injected through the liquid inlet hole 14, one of the first liquid outlet hole 15 and the second liquid outlet hole 16 is used to supply liquid to the outside, and the other is used to discharge liquid containing bubbles and impurities. The above-mentioned liquid separation device 100 is provided with a first seal 21 and a second seal 22, which improve the sealing performance when the first movable part 23 abuts against the bottom 113 of the first diverter groove 11 and the sealing performance when the second movable part 25 abuts against the bottom 123 of the second diverter groove 12. The first seal 21 is movably arranged to abut against the bottom 113 of the first diverter groove 11, and the second seal 22 is movably arranged to abut against the bottom 123 of the second diverter groove 12, which can reduce the friction between the first seal 21 and the second seal 22 and other structures, improve the service life, and avoid the formation of debris due to friction of the seal entering the liquid, thereby affecting the product quality.

[0077] In some embodiments, see Figure 7 and Figure 8 The first annular groove 231 and the second annular groove 251 are dovetail grooves. Specifically, the notch width of the first annular groove 231 is smaller than the diameter of the first seal 21, and the diameter of the first seal 21 is smaller than the width of the bottom of the first annular groove 231. The notch width of the second annular groove 251 is smaller than the diameter of the second seal 22, and the diameter of the second seal 22 is smaller than the width of the bottom of the second annular groove 251. In this way, the first seal 21 can be embedded in the first annular groove 231, and the second seal 22 can be embedded in the second annular groove 251, so as to prevent the first seal 21 and the second seal 22 from falling off.

[0078] See also Figure 7 and Figure 8 The first sealing member 21 has a circular cross section, is disposed in the first annular groove 231 and partially extends out of the first annular groove 231, so that when the first movable member 23 abuts against the groove bottom 113 of the first shunt groove 11, the first sealing member 21 abuts against the groove bottom 113 of the first shunt groove 11. The second sealing member 22 has a circular cross section, is disposed in the second annular groove 251 and partially extends out of the second annular groove 251, so that when the second movable member 25 abuts against the groove bottom 123 of the second shunt groove 12, the second sealing member 22 abuts against the groove bottom 123 of the second shunt groove 12.

[0079] The cross-sections of the first seal 21 and the second seal 22 are both set to be circular, which can improve the force uniformity when the first seal 21 abuts the groove bottom 113 of the first diverter groove 11 and the second seal 22 abuts the groove bottom 123 of the second diverter groove 12, thereby improving the sealing performance. At the same time, the circular cross-section has better elasticity and recovery, and can quickly restore its original shape after being compressed or deformed. The first seal 21 extends out of the first annular groove 231, so that the first seal 21 abuts the groove bottom 113 of the first diverter groove 11, thereby improving the sealing performance. The second seal 22 extends out of the second annular groove 251, so that the second seal 22 abuts the groove bottom 123 of the second diverter groove 12, thereby improving the sealing performance.

[0080] In some embodiments, see Figure 4 , Figure 7 and Figure 8 , the radius of the connecting portion 24 is smaller than the radius of the connecting hole 13, and the length of the connecting portion 24 is greater than the length of the connecting hole 13. It can be understood that the radius of the connecting portion 24 is smaller than the radius of the connecting hole 13, so that the liquid can flow between the side wall of the connecting hole 13 and the side wall of the connecting portion 24. The length of the connecting portion 24 is greater than the length of the connecting hole 13, so that when the second movable member 25 abuts against the groove bottom 123 of the second diverter groove 12, a first space 40 can be formed between the first movable member 23 and the groove bottom 113 of the first diverter groove 11, and when the first movable member 23 abuts against the groove bottom 113 of the first diverter groove 11, a second space 50 can be formed between the second movable member 25 and the groove bottom 123 of the second diverter groove 12.

[0081] In some embodiments, see Figure 5 , Figure 6 , Figure 7 and Figure 8 , the two ends of the connecting portion 24 have a first step portion 241 and a second step portion 242. When the first sealing member 21 on the first movable member 23 abuts against the bottom 113 of the first shunt groove 11, the first step portion 241 is inserted into the connecting hole 13. When the second sealing member 22 on the second movable member 25 abuts against the bottom 123 of the second shunt groove 12, the second step portion 242 is inserted into the connecting hole 13. The radii of the first step portion 241 and the second step portion 242 are the same as the radius of the connecting hole 13. In this way, when the first sealing member 21 on the first movable member 23 abuts against the bottom 113 of the first shunt groove 11, the first step portion 241 is inserted into the connecting hole 13 to improve the sealing performance. When the second sealing member 22 on the second movable member 25 abuts against the bottom 123 of the second shunt groove 12, the second step portion 242 is inserted into the connecting hole 13 to improve the sealing performance.

[0082] In some embodiments, see Figure 3 , Figure 7 and Figure 8The liquid separation device 100 further includes a first guide sleeve 60 and a second guide sleeve 70. The first guide sleeve 60 is partially covered on one end surface of the liquid separation seat 10 and partially inserted into the first diverter groove 11, and is sleeved outside the first movable member 23. The first guide sleeve 60 is used to guide the first movable member 23. The second guide sleeve 70 is partially covered on the other end surface of the liquid separation seat 10 and partially inserted into the second diverter groove 12, and is sleeved on the second movable member 25. The second guide sleeve 70 is used to guide the second movable member 25.

[0083] The first guide sleeve 60 is used to guide the first movable member 23, and the second guide sleeve 70 is used to guide the second movable member 25, so that the first movable member 23 and the second movable member 25 can always move in the direction from the first guide sleeve 60 to the second guide sleeve 70, avoiding the movement direction of the first movable member 23 and the second movable member 25 from being offset, causing interference between the first movable member 23 and the first diverter groove 11, and interference between the second movable member 25 and the second diverter groove 12, thereby improving the stability of operation.

[0084] In some embodiments, see Figure 7 and Figure 8 The first shunt groove 11 and the second shunt groove 12 are step grooves. The first shunt groove 11 includes a first movable groove 111 and a first liquid flow groove 112 connected to form a step shape. The second shunt groove 12 includes a second movable groove 121 and a second liquid flow groove 122 connected to form a step shape. The first movable member 23 sequentially passes through the first movable groove 111 and the first liquid flow groove 112 and forms a first space 40 with the bottom of the first liquid flow groove 112 (i.e., the bottom 113 of the first shunt groove 11). The second movable member 25 sequentially passes through the second movable groove 121 and the second liquid flow groove 122 and forms a second space 50 with the bottom of the second liquid flow groove 122 (i.e., the bottom 123 of the second shunt groove 12). The first guide sleeve 60 is partially covered on the end surface of the liquid separation seat 10 and partially inserted into the first movable groove 111, and is sleeved outside the first movable member 23. The second guide sleeve 70 is partially covered on the end surface of the liquid dispensing seat 10 , partially inserted into the second movable groove 121 , and sleeved outside the second movable member 25 .

[0085] In some embodiments, the liquid separation device 100 further includes a third seal 80 and a fourth seal 90. The third seal 80 is sleeved outside the first movable member 23, and the first guide sleeve 60 presses the third seal 80 against the first movable groove 111, which is used to seal the first liquid flow groove 112, and prevent the liquid transported to the first liquid flow groove 112 from overflowing from the connection between the groove wall of the first liquid flow groove 112 and the first guide sleeve 60, which is beneficial to improve the stability of liquid transport by the liquid separation device 100. The fourth seal 90 is sleeved outside the second movable member 25, and the second guide sleeve 70 presses the fourth seal 90 against the second movable groove 121, which is used to seal the second liquid flow groove 122, and prevent the liquid transported to the second liquid flow groove 122 from overflowing from the connection between the groove wall of the second liquid flow groove 122 and the second guide sleeve 70, which is beneficial to improve the stability of liquid transport by the liquid separation device 100. In this embodiment, the third seal 80 and the fourth seal 90 can be oil seals, i.e., V-shaped sealing rings.

[0086] In some embodiments, see Figure 3 , Figure 5 and Figure 6 The first movable member 23 is further provided with a first mounting groove 2311, which is communicated with the first annular groove 231, and the second movable member 25 is further provided with a second mounting groove 2511, which is communicated with the second annular groove 251. The first mounting groove 2311 is provided to facilitate installation and removal of the first sealing member 21, and the second mounting groove 2511 is provided to facilitate installation and removal of the second sealing member 22.

[0087] In some embodiments, see Figure 3 The first movable member 23 has a snap-in groove 232 at one end away from the connecting portion 24, and the snap-in groove 232 is used to snap-in the output end of the driving member 30 so as to connect the driving member 30 and the first movable member 23. By providing the snap-in groove 232, the connection between the driving member 30 and the first movable member 23 can be facilitated. Moreover, when disassembling the first movable member 23 and the second movable member 25, the driving member 30 can be removed first, and then a pin or a rod can be inserted into the snap-in groove 232, and then the second movable member 25 can be disassembled.
