The type of the telescopic motor 1 is a stepping motor, which can accurately control the moving distance of the piston push rod 201 and ensure the accurate measurement of the liquid. The push-pull piston 2 is made of transparent plastic material, which is convenient for observing the internal liquid condition, and the push-pull piston 2 is horizontally arranged to facilitate the control of the telescopic motor 1. Then, the piston push rod 201 is movably arranged in the push-pull piston 2, one end of the piston push rod 201 is provided with a limiting plate 202, and the piston push rod 201 is drivingly connected with the telescopic motor 1 through the limiting plate 202. That is, the telescopic shaft on the telescopic motor 1 is connected with the limiting plate 202, so as to drive the piston push rod 201 to make telescopic movement in the push-pull piston 2. The liquid storage bottle 3 is arranged on one side of the push-pull piston 2, the liquid storage bottle 3 can be made of polypropylene material, the liquid storage bottle 3 is respectively provided with a liquid inlet 301 and a liquid outlet 302, the liquid inlet 301 is communicated with the gas flow port 203 on the push-pull piston 2 through a liquid inlet pipe 303, and a liquid outlet pipe 304 is connected at the liquid outlet 302, and the liquid inlet pipe 303 and the liquid outlet pipe 304 can be silica gel pipes.

The control panel 5 has a microcontroller and is electrically connected with the telescopic motor 1, the telescopic motor 1 is accurately controlled through programming, the measurement of the liquid can be accurately controlled, the accuracy of liquid adding can be ensured every time, the need for manual operation is reduced, the possibility of human error is reduced, and the work efficiency is improved. Secondly, one end of the liquid outlet pipe 304 is located in the liquid storage bottle 3 and at the bottom of the liquid storage bottle, and the other end is located above the liquid adding port 401, the liquid in the liquid storage bottle 3 enters the liquid outlet pipe 304 through the one end of the liquid outlet pipe 304 at the bottom, and finally flows out through the other end of the liquid outlet pipe 304 above the liquid adding port 401, so that the liquid can smoothly flow from the liquid storage bottle 3 to the liquid adding box 4.

[0023] As a preferred embodiment, the control panel 5 can integrate a touch screen to facilitate user operation, the user can directly set the liquid adding amount and speed on the screen, and the control panel 5 can also integrate a liquid crystal display screen, which can display the current liquid adding amount and the remaining liquid amount.

[0024] In the embodiment, the single-connection micro switch 6 is arranged at the piston push rod 201 and is electrically connected with the control panel 5. The single-connection micro switch 6 is provided with a first limiting rod 601, which is arranged in abutment with a first end surface of the limiting plate 202. The single-connection micro switch 6 at the piston push rod 201 is a mechanical single-connection micro switch 6, which is arranged in abutment with the limiting plate 202 on the piston push rod 201 through the first limiting rod 601. When the piston push rod 201 moves forward to a predetermined position, the first end surface of the limiting plate 202 abuts against the first limiting rod 601 and triggers the single-connection micro switch 6.

The double-connection micro switch 7 is provided with a second limiting rod 701, which is arranged in abutment with a second end surface of the limiting plate 202. When the piston push rod 201 moves backward to a predetermined position, the second end surface of the limiting plate 202 abuts against the second limiting rod 701 and triggers the double-connection micro switch 7. After the control panel 5 receives the signal, the driving direction of the telescopic motor 1 is changed. In order to control more accurately, a time delay relay 9 is also used in this control process. When the second end surface of the limiting plate 202 abuts against the second limiting rod 701, the control panel receives a stop signal from the time delay relay 9, and the piston push rod 201 stops moving, effectively preventing the piston push rod 201 from moving backward excessively and causing damage to the structure of the telescopic motor 1. Further, the position of the double-connection micro switch 7 can also be adjusted according to the actual liquid outlet demand. The farther the position of the double-connection micro switch 7 is from the piston push rod 201, the greater the liquid outlet amount is.
