The bottom end of the connecting tube 412 is close to the bottom wall of the closed cavity 401, which helps the connecting tube 412 to continuously deliver paraffin liquid.

[0049] A sealing ring 413 is provided on the inner wall of the connection hole 411.

[0050] Reference Figures 2 to 3As shown, multiple paraffin containers 400 are placed in the receiving groove 110. The connecting seats 410 on the top of the multiple paraffin containers 400 are inserted into the multiple positioning grooves 311 of the positioning mechanism 300 one by one. The connecting holes 411 of the multiple connecting seats 410 abut against the multiple docking holes 320 of the positioning mechanism 300 one by one. The paraffin delivery tube in the docking hole 320 is inserted into the connecting hole 411. The sealing ring 413 seals the gap between the outer wall of the paraffin delivery tube and the inner wall of the connecting hole 411 to prevent paraffin liquid from leaking from the gap between the outer wall of the paraffin delivery tube and the inner wall of the connecting hole 411.

[0051] When the paraffin in the paraffin container 400 needs to be replaced, open the door 200 on the front side of the receiving chamber 100, remove the paraffin container 400 from the opening 111 of the receiving groove 110, and separate the connecting hole 411 from the docking hole 320 to allow the paraffin delivery tube to detach from the connecting hole 411, thus completing the disassembly of the paraffin container 400. After replacing the paraffin in the paraffin container 400, put the paraffin container 400 back into the receiving groove 110. The positioning part 310 of the positioning mechanism 300 positions the paraffin container 400 in the left-right direction, ensuring that the connecting hole 411 of the connecting seat 410 of the paraffin container 400 is aligned with the docking hole 320 of the positioning mechanism 300. Then, push the paraffin container 400 to move from front to back, thereby allowing the paraffin delivery tube on the docking hole 320 to be inserted into the connecting hole 411, so that the paraffin delivery tube is connected to the interior of the paraffin container 400, thus completing the installation of the paraffin container 400. Therefore, the operation of removing or installing the paraffin container 400 from the paraffin storage component is relatively convenient.

[0052] In some embodiments, the paraffin storage assembly is further provided with a temperature control device, which is disposed on the top and bottom walls of the container. The temperature control device is an electric heater. The temperature control device is activated to heat the container 110, so that the multiple paraffin containers 400 in the container 110 are kept within a constant temperature range. In this embodiment, in order to ensure that the paraffin in the paraffin containers 400 is in a molten liquid state, the temperature control device controls the temperature of the container 110 between 60°C and 65°C.

[0053] In some embodiments, the positioning part 310 of the positioning mechanism 300 may take various forms.

[0054] For example, the positioning part 310 is a vertical plate arranged in the front-to-back direction. The two vertical plates are respectively arranged on the left and right sides of the connecting seat 410, and the connecting seat 410 is positioned in the left-to-right direction by the two vertical plates.

[0055] Alternatively, the positioning part 310 is located at the top of the receiving groove 110. The positioning part 310 is a downward protruding guide block. The bottom of the connecting seat 410 is provided with a sliding groove that runs through the front and back. The sliding groove cooperates with the guide block to restrict the position of the connecting seat 410 in the left and right directions.

[0056] Alternatively, the positioning part 310 is a forward-extending tube, the position of which corresponds to the position of the connecting hole 411 of the connecting seat 410. A paraffin delivery tube is installed inside the tube, and the tube is inserted into the connecting hole 411 to restrict the position of the connecting seat 410 in the left and right directions.

[0057] This invention also provides a tissue dehydrator, including the paraffin storage component described in the above embodiments.
