[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a device for cleaning and sterilizing biological experimental equipment, including a cleaning box 1. The upper surface of the cleaning box 1 is fixedly connected to a connecting box 2. The interior of the cleaning box 1 communicates with the interior of the connecting box 2 through a circular through hole. A circular through hole is provided on the upper surface of the cleaning box 1 for the vertical movement of a rack 16. The inner wall of the circular through hole is bonded and fixed to a sealing ring. The sealing ring prevents heat from the interior of the cleaning box 1 from dissipating through gaps during the vertical movement of the rack 16, thus reducing air contamination inside the cleaning box 1. The side of the cleaning box 1 is fixedly connected to an electric push rod 19 by bolts. The output end of the electric push rod 19 is fixedly connected to a top plate 20. The top plate 20 and the top end of the sleeve 13 are rotatably engaged by a bearing. A circular through hole is provided on the upper surface of the connecting box 2 for the vertical movement of the rack 16, thereby facilitating the user to remove the equipment on the rack 16.

[0021] The cleaning tank 1 is fixedly connected to the fixing plate 3. The fixing plate 3 divides the interior of the cleaning tank 1 into an upper cleaning chamber and a lower liquid storage chamber. Several reflux holes are formed on the surface of the fixing plate 3 to connect the cleaning chamber and the liquid storage chamber. The upper surface of the fixing plate 3 is provided with a slope for guiding the flow, preventing the cleaning fluid from accumulating in the center of the fixing plate 3. The reflux holes facilitate the recycling and reuse of the cleaning fluid. A drain pipe and a liquid inlet pipe are provided on the side of the cleaning tank 1 for easy addition and discharge of the cleaning fluid by the user.

[0022] The fixed plate 3 is rotatably connected to the outer side of the rotating shaft 4 via a sealed bearing. The outer side of the rotating shaft 4 is fixedly connected to the driven gear 5. The bottom surface of the fixed plate 3 is fixedly connected to the partition plate 8, forming a closed space to prevent liquid in the storage chamber from entering the interior of the partition plate 8. Heat dissipation holes for the motor 6 are provided at the bottom of the cleaning tank 1. The partition plate 8 is fixedly connected to the motor 6 via bolts. The output end of the motor 6 is connected to the drive gear 7. Both the driven gear 5 and the drive gear 7 are bevel gears, and the drive gear 7 meshes with the outer side of the driven gear 5.

[0023] The bottom end of the rotating shaft 4 is rotatably connected to one end of the steam pipe 9, and the other end of the steam pipe 9 is fixedly connected to the output end of the steam generator.

[0024] The fixing plate 3 is connected to the outside of the spray pipe 10. Several spray heads are fixedly installed on the outside of the spray pipe 10. The pump body 11 is fixedly installed inside the liquid storage chamber. The output end of the pump body 11 is connected and fixed to the spray pipe 10.

[0025] An air hole 12 is provided on the outer side of the rotating shaft 4. The air hole 12 is inclined to prevent the air from being blocked by the outer side of the placement rack 16 and thus unable to blow air onto the instruments. A sleeve 13 is fitted on the outer side of the rotating shaft 4. The outer side of the sleeve 13 is fixedly connected to the clamping plate 15. A placement rack 16 is provided on the outer side of the sleeve 13. The placement rack 16 can be different types of supports according to actual use, that is, different instruments can be placed through different placement racks 16. A sterilization lamp 18 is fixedly installed on the inner wall of the connecting box 2.

[0026] The rotating shaft 4 is hollow inside, and a limiting groove 14 is formed on the outer side of the rotating shaft 4. The rotating shaft 4 slides with the sleeve 13 through the limiting groove 14, so that the sleeve 13 and the rotating shaft 4 rotate synchronously. The sleeve 13 has a relief hole on its outer side that matches the air hole 12. The clamping plate 15 and the relief hole are alternately distributed. The clamping plate 15 is an L-shaped plate, and the clamping plate 15 is engaged with the clamping groove 17. The mounting bracket 16 has a clamping groove 17 on its side.

[0027] Working principle: In use, connect one end of the steam pipe 9 to the output end of the steam generator. The electric push rod 19 causes the top plate 20 to move the placement rack 16 upwards until it is removed from the connection box 2. Then, the user places the cleaning equipment onto the placement rack 16 one by one. The user can select different placement racks 16 according to the actual needs and adjust the spacing between the placement racks 16. When installing the placement rack 16, insert the retaining plate 15 into the placement rack 16 to fix it to the outside of the sleeve 13. Conversely, the placement rack 16 can be disassembled.

[0028] The placement rack 16 is then moved into the cleaning tank 1. The cleaning liquid is sprayed out from the nozzle outside the spray pipe 10 by the pump body 11. The motor 6 drives the drive gear 7 to rotate the rotating shaft 4 and the driven gear 5. The rotation of the placement rack 16 enhances the spraying effect of the spray pipe 10 and reduces cleaning dead corners. At the same time, the steam pipe 9 sprays high-temperature steam from the air hole 12, which enhances the sterilization effect of the instrument and disperses the liquid on the outside of the instrument. The electric push rod 19 moves the top plate 20 to lift the placement rack 16 so that the instrument can be taken out. During the process, the sterilization lamp 18 further achieves the sterilization effect.
