DETAILED DESCRIPTION

[0019] In order to make the technical solution of the utility model clearer, the utility model is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Embodiment 1:

[0021] like Figure 1- 2, according to one aspect of the utility model, a waterproof structure of an ultrasonic cleaning machine is provided, including a body 1, an opening and closing cover 2, and a power switch 3 on the surface of the body 1, an inner plate 4 is provided on the inner side of the opening and closing cover 2, wherein a power supply board 8 is fixedly installed between the opening and closing cover 2 and the inner plate 4, four sterilization lamps 5 are installed on the surface of the power supply board 8, and four openings 10 are provided on the surface of the inner plate 4, and the four openings 10 correspond to the positions of the four sterilization lamps 5 one by one. Four sterilization lamps 5 are arranged inside the opening and closing cover 2, so that after the object to be processed is placed inside the body 1, the four sterilization lamps 5 can sterilize the object inside the body 1 without dead angles.

[0022] Embodiment 2:

[0023] like Figure 1 - As shown in FIG. 4 , a lifting seal ring 6 capable of lifting and lowering is provided between the inner edge of the opening and closing cover 2 and the outer edge of the inner plate 4, and a limiting ring 12 (such as Figure 4 As shown in the figure, the limiting ring 12 can prevent the lifting seal ring 6 from detaching from the opening and closing cover 2. A sealing base 13 is provided at the inner edge of the opening and closing cover 2, and an annular airbag 11 is provided between the sealing base 13 and the limiting ring 12, wherein the upper part of the annular airbag 11 is connected to the inner surface of the limiting ring 12. Sealing cylinders 9 are provided on the inner surfaces of the left and right sides of the inner plate 4, wherein the interior of the sealing cylinder 9 is an extrusion cavity 16 with a smooth inner wall, and the bottom of the sealing cylinder 9 is connected to a connecting pipe 14, and the other end of the connecting pipe 14 is connected to the sealing base 13. Pressure columns 7 are provided throughout the interior of the sealing cylinders 9 on both sides, and a lifting ring 17 is provided at the bottom end of the pressure column 7 and located inside the sealing cylinder 9, and the surface of the lifting ring 17 is provided with two rubber rings 18, wherein the rubber ring 18 is in sealing contact with the inner surface of the sealing cylinder 9.
