[0027] The second embodiment differs from the first embodiment mainly in that:

[0028] The positioning member 5 includes a cylinder 51 arranged in an array corresponding to the movable groove 415. A filter plate 52 is provided at the upper end of the inner side of the cylinder 51. Four sets of slide rods 53 are slidably connected to the inner edge of the cylinder 51 near the upper side of the filter plate 52. A positioning block 54 is installed on the slide rod 53 near the middle of the filter plate 52.

The slide rod 53 is released. Under the action of the spring 55, the positioning block 54 clamps the container. When the cylinder 51 is located in the protective shell 412 and the discharge ring 414 sprays water, the cylinder 51, positioning block 54, spring 55, and filter plate 52 are sprayed and cleaned, and the excess water is discharged to the waste liquid recovery end through the drain pipe 56.

[0030] At the same time, the contents not described in detail in this specification belong to the existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0031] During use, the user positions the container containing the biological tissue slices on the filter plate 52 inside the barrel 51 through the array slide bar 53, the positioning block 54, and the spring 55. After the container is positioned, the electric push rod assembly 2 is started. The electric push rod assembly 2 drives the positioning member 5 and the container upward through the push plate 3. After the barrel 51 drives the filter plate 52, the slide bar 53, the positioning block 54, and the spring 55 to be introduced into the protective shell 412 through the movable groove 415, and the bottom of the dropper 413 is inserted into the open end of the container, the electric push rod assembly 2 is closed, and the dye is supplied to the dropper 413 through the liquid supply part 44.

After the dyeing is completed, each link is reset and the container is taken out.

[0032] The upper side of the cylinder 51 is re-entered into the protective shell 412, and the water pump 425 is started. The water pump 425 draws water from the outside, and then the drawn water is sprayed out through the branch pipe 426, the three-way valve 424, the bifurcated pipe 43, and the discharge ring 414. The discharge ring 414 sprays water to clean the inner wall of the protective shell 412, the cylinder 51, the positioning block 54, the spring 55, and the filter plate 52, thereby promoting the separation of the residual dye attached to the surface of the above components. The mixture of the residual dye and water is discharged through the drainage pipe 5 6 is discharged to the external waste liquid recovery end, and then the water pump 425 is turned off to supply heat to the heating plate in the heating shell 423, so that the three-way valve 424 is reversed, and the air pump 421 is turned on. The air pump 421 extracts external gas and introduces it into the heating shell 423 through the conduit 422. The heating shell 423 converts the gas into hot gas, and then the hot gas blows and dries the inner wall of the protective shell 412, the positioning block 54, the spring 55, and the filter plate 52 through the three-way valve 424, the bifurcated pipe 43, and the discharge ring 414.
