During the process of the driving motor 303 driving the threaded shaft 301 to rotate, the moving part 302 can move along the threaded shaft 301 in the direction of approaching or moving away from each other.

[0034] like Figure 1 As shown, the main unit 1 includes a sterilization tank body 101 and support feet 102 installed at the bottom of the sterilization tank body 101. The setting of the support feet 102 provides support for the stable operation of the entire sterilization tank.

[0035] like Figure 1 and Figure 2 As shown, the main unit 1 also includes a sealing cover 103 arranged on the top of the sterilization tank body 101, and a lifting handle 104 installed on the top of the sealing cover 103.

The provision of the lifting handle 104 facilitates the movement of the sealing cover 103.

[0048] like Figure 3 As shown, the heating unit 2 also includes a plurality of heating tubes 205 installed between the steam delivery tube 201 and the heating cylinder 203, and the plurality of heating tubes 205 are arranged in a circular array. The arrangement of the heating tubes 205 can heat the steam again.

[0049] like Figure 4 As shown, the connecting member 305 includes a lower connecting seat 3051 installed on the top of the movable member 302, an upper connecting seat 3052 installed on the bottom of the placement plate 304, and a connecting rod 3053 with one end movably connected to the upper connecting seat 3052 and the other end movably connected to the lower connecting seat 3051. The setting of the connecting member 305 can convert the left and right movement of the movable member 302 along the threaded shaft 301 into the up and down movement of the placement plate 304.

[0050] like Figure 4As shown, there are two groups of integral structures composed of moving parts 302 and connecting parts 305, and the integral structures composed of the two groups of moving parts 302 and connecting parts 305 are symmetrically arranged about the bisecting plane of the threaded shaft 301, so as to facilitate the up and down movement of the placement plate 304.

[0051] like Figure 3 As shown, the warning unit 4 includes a baffle 401 installed on the top of the placement tray 304, and a receiving plate 402 installed on the bottom of the sealing cover 103.
