[0054] As shown in 7-9, the driving member includes two first racks 344 respectively fixed to the two sliders 342, and the teeth of the two first racks 344 are arranged correspondingly, the two first racks 344 are meshingly connected with a gear 346, and a first motor 347 is fixed on the mounting frame 341 through a support, and the output end of the first motor 347 is connected to the gear 346. When the first motor 347 is running, the two first racks 344 cooperate with the gear 346 to realize synchronous driving of the two pressure wheels 345 to move, thereby clamping or loosening the liquid storage hose 33.

[0055] like Figure 1-3 As shown, the extrusion assembly 34 is driven by a linear drive assembly to move along the length direction of the liquid storage hose 33.

[0057] When the extrusion assembly 34 moves to the lower limit position, the first motor 347 is operated in the reverse direction, and the two pressure wheels 345 will move away from each other until the first rack 344 is no longer engaged with the gear 346 and the spring 343 is compressed. When the first motor 347 continues to be operated in the reverse direction, under the action of the second rack 351 and the gear 346, the outer cylinder 352 and the inner ring magnet block 355 will continue to move downward, so that the bottom position of the liquid storage hose 33 can be quickly restored. Then the first motor 347 is operated in the forward direction to make the outer cylinder 352 rise, and at the same time, the two sliders 342 move to one side of the gear 346 under the action of the spring 343, the first rack 344 is engaged with the gear 346, and the two pressure wheels 345 are close to each other. It should be noted that: during the operation, the size design is required to avoid interference between the pressure wheel 345 and the outer cylinder 352.
