At this time, by utilizing the elastic force of the first spring 5051, the linkage block 505 can slide in the opposite direction along the second slide groove 5013 under the action of the elastic force of the first spring 5051, so that with the help of the mutual cooperation between the second rack 5054 and the second gear 5055, the valve ball 433 on the rotating rod 5018 is rotated and reset, thereby changing the flow channel of the valve ball 433.

[0060] In the above technical solution, the cylinder 63 on the top end cover 62 is used to enable the push plate to press the unused filter cotton 507 in the storage cylinder 61, so that the filter cotton 507 in the storage cylinder 61 can slide downward along the axial direction of the storage cylinder 61. Therefore, after the filter cotton 507 is pressed to a certain position, the elastic plug block 5061 is used to install the filter cotton 507 on the limiting ring 506, and the used filter cotton 507 in the limiting ring 506 can be pressed by the push plate, so that the used filter cotton 507 The filter cotton 507 can fall off from the limiting ring 506 and fall into the recovery tube 64 by its own weight, thereby achieving the effect of collecting the used filter cotton 507; and by utilizing the top end cover 62, it is possible to conveniently add new filter cotton 507 to the storage tube 61; and by utilizing the bottom end cover 66, after the recovery tube 64 collects a certain amount of filter cotton 507, by opening the bottom end cover 66, it is possible to conveniently clean the used filter cotton 507 in the recovery tube 64.

[0061] Working principle: when the filter cotton 507 needs to be replaced, the cylinder 63 on the top end cover 62 is used to enable the push plate to press the unused filter cotton 507 in the storage cylinder 61, so that the filter cotton 507 in the storage cylinder 61 can slide downward along the axial direction of the storage cylinder 61. Therefore, after the filter cotton 507 is pressed to a certain position, the elastic plug block 5061 is used to install the filter cotton 507 on the limiting ring 506, and the used filter cotton 507 in the limiting ring 506 is pressed by the push plate, so that the used filter cotton 507 07 can fall off from the limiting ring 506, and thus fall into the recovery cylinder 64 by virtue of its own weight; then, by utilizing the driving motor 5031 on the mounting plate 41, the first pulley 5032 and the plurality of second pulleys 5034 are transmitted through the transmission belt 5035, so that the process shaft 5033 on the mounting plate 41 is rotated, thereby driving the first gear 5036 on the bottom end of the shaft 5033 to rotate, and by utilizing the mutual cooperation between the first gear 5036 and the first rack 5037, the sliding drive plate 5032 on the fixed side plate 501 is enabled to move. 04 can slide along the first slide groove 5012; by using the driving plate 504 on the fixed side plate 501, the driving plate 504 can slide along the second slide groove 5013 under the action of the driving mechanism, and by using the lower plate member 5042, the lower plate groove 5043 on the lower plate member 5042 can abut against the second pulley 5025 on the T-shaped rotating plate 5023, so that the driving plate 504 can drive the sliding plate 502 to slide along the guide groove 5041 on the driving plate 504 during the sliding process of the driving plate 504 along the second slide groove 5013; and when the driving plate 504 After sliding to the position of the upper plate 5015, the upper plate 5015 is used to limit the T-shaped rotating plate 5023, so that the T-shaped rotating plate 5023 on the vertical plate 5022 can be rotated, and then the first pulley 5024 on the T-shaped rotating plate 5023 can be rotated to the upper plate groove 5016 provided on the upper plate 5015, thereby playing the effect of limiting the sliding of the sliding plate 502, and at this time, the limiting ring 506 slides between the sampling tube and the dripping tube, and the upper and lower ends of the limiting ring 506 are respectively connected to the bottom end face of the sampling tube and the top end face of the dripping tube;By utilizing the transmission assembly, after the filter cotton 507 is replaced, the limiting ring 506 on the sliding plate 502 allows the driving plate 504 to continue to slide along the first sliding groove 5012 under the cooperation between the first gear 5036 and the first rack 5037. By utilizing the lever 5044 on the driving plate 504, the driving plate 504 can drive the linkage block 505 to overcome the elastic force of the first spring 5051 and slide along the direction of the second sliding groove 5013 during the sliding process of the driving plate 504 along the first sliding groove 5012. Therefore, by utilizing the cooperation between the second rack 5054 on the linkage block 505 and the second gear 5055 on the rotating rod 5018, The valve ball 433 is driven to rotate, and the flow channel is changed by rotating the valve ball 433, so that the filtered front end waste liquid can be discharged conveniently.
