When the wax liquid drips downward, it will first contact the conical medium collection cover and flow into the bottom medium storage cavity through the medium discharge hole, and finally fall on the surface of the bottom medium storage cavity. The bottom medium storage cavity is heated and the wax liquid will not solidify. After the transfer is completed, the bottom box is removed and the conical medium collection cover is opened to clean the liquid wax, thereby realizing the heating and melting function of the wax liquid, which is convenient for care.
