[0041] In the present embodiment, the provision of the pump mechanism provides stable disinfectant liquid conveying power for the sterilization and disinfection device. The pump mechanism comprises a protective shell 11, a pump body 12, a liquid inlet pipe 13 and a liquid outlet pipe 14. The protective shell 11 is fixedly installed on the solution tank 2, which protects the pump body 12 from damage caused by external factors. The pump body 12 is fixedly installed in the protective shell 11 and is the core component of the pump mechanism, which is responsible for pumping and conveying the disinfectant liquid in the solution tank 2. The liquid inlet pipe 13 is installed at the liquid inlet end of the pump body 12, and its liquid inlet end extends into the solution tank 2 to ensure that the disinfectant liquid can be smoothly introduced into the pump body 12. The liquid outlet pipe 14 is installed at the liquid outlet end of the pump body 12, and its liquid outlet end extends into the solution channel of the support column 4 through the transmission space, which is used to convey the pumped disinfectant liquid to the spray pipe 9 and then to the surface of the articles on the article circular plate 8.

In specific operation, the plunger pump 12 sucks the disinfectant liquid in the solution tank 2 through the liquid inlet pipe 13 and conveys it to the solution channel of the support column 4 in a high-pressure manner through the liquid outlet pipe 14. The disinfectant liquid then flows into the spray pipe 9 and is atomized into fine droplets by the spray heads 15, which are uniformly sprayed on the surface of the articles on the article circular plate 8. This atomized spraying method can make the disinfectant liquid more uniformly cover the surface of the articles, improving the disinfection effect.

[0058] In the embodiment, in order to improve the sterilization and disinfection effect, a vibration driving mechanism is additionally arranged. The mechanism comprises a driven shaft 38 rotatably installed on the other side of the sterilization box 1 corresponding to the cabinet door 21, and one end of the driven shaft 38 is located in the transmission space and fixedly installed with a driven bevel gear 39. The driven bevel gear 39 is engaged with the bevel gear disc 18, and the driven shaft 38 is driven to rotate by the support column 4. In addition, the bottom of each inner cylinder 5 and outer cylinder 6 is fixedly installed with a metal spring 34, the bottom of the metal spring 34 is connected with an L-shaped support 33, and the L-shaped support 33 is further fixed to the bottom of the storage circular plate 8, so as to realize the suspension support of the storage circular plate 8.

The bottom of the storage circular plate 8 is fixedly installed with a stress sheet 37 which is in contact with the push cam 36. When the camshafts 35 rotate, the push cam 36 pushes the stress sheet 37, so that the storage circular plate 8 moves upward, and the L-shaped support 33 moves upward and compresses the metal spring 34. The other end of the driven shaft 38 and the camshafts 35 located outside the sterilization box 1 are installed with synchronous pulleys 40, and the synchronous pulleys 40 are sleeved with the same synchronous belt 42 as the tension pulleys 41, so as to realize the rotation of the plurality of camshafts 35 driven by the driven shaft 38.

First, the linkage design of the driven shaft 38 and the support column 4 utilizes the rotating power of the support column 4, without the need for an additional power source, to realize stable rotation of the driven shaft 38. Second, the combination of the metal spring 34 and the L-shaped bracket 33 provides reliable suspension support for the storage circular plate 8, enabling it to remain stable during vibration. The setting of the camshaft 35 and the push cam 36 periodically pushes the stressed sheet 37, causing the storage circular plate 8 to vibrate up and down. This vibration can effectively enhance the contact between the disinfectant and the articles, making the disinfectant more evenly distributed on the surface of the articles. Especially for articles with complex shapes or irregular surfaces, vibration can make the disinfectant penetrate better into the gaps and corners of the articles, significantly improving the uniformity and completeness of disinfection. The transmission design of the synchronous wheel 40, the synchronous belt 42 and the tensioning wheel 41 ensures the synchronous rotation between the driven shaft 38 and the multiple camshafts 35, making the vibration of each storage circular plate 8 consistent, improving the stability and reliability of the equipment operation. The installation of the stabilizing frame 43 further enhances the rotation stability of the camshaft 35, reduces the impact of vibration on the equipment structure, and prolongs the service life of the equipment.
