A spring is arranged between the slider and the corresponding cross plate. The spring is sleeved outside the sliding rod. One end of the spring is fixedly connected to the slider, and the other end of the spring is fixedly connected to the cross plate. An arc plate is fixedly connected between the corresponding two sliders. The arc plate is in an arc-shaped structure. The surfaces of the two arc plates facing each other are concave surfaces.

[0008] Preferably, the driving component includes a rotating shaft and a motor. The rotating shaft is rotatably connected to the side wall of the box body.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The present invention provides a cleaning and disinfection device for an experimental instrument as shown in Figures 1-6 the figure, including a box body 1. A placement opening 21 is provided on the box body 1, and operations on the experimental instrument are carried out through the opening. A square pipe 2 is rotatably arranged inside the box body 1, and a driving component for driving the square pipe 2 to rotate is arranged on the box body 1. The driving component includes a rotating shaft 19 and a motor 20. The rotating shaft 19 is rotatably connected to the side wall of the box body 1, the square pipe 2 is fixedly connected to the rotating shaft 19, the motor 20 is fixedly connected to the outer wall of the box body 1, and the rotating shaft 19 is fixedly connected to the driving shaft of the motor 20.

[0026] Specifically, the rotation of the motor 20 drives the rotation of the rotating shaft 19, and the rotation of the rotating shaft 19 drives the rotation of the square pipe 2.

[0027] A plurality of round pipes 3 are penetrated through the upper and lower ends of the square pipe 2. The plurality of round pipes 3 are equidistantly distributed, and the round pipes 3 at the upper and lower ends correspond to each other one by one. The round pipe 3 is rotatably connected to the square pipe 2. One end of the round pipe 3 located outside the square pipe 2 is fixedly connected with a bracket 9. The bracket 9 is in an L-shaped structure. Two brackets 9 are provided, and the two brackets 9 are symmetrically distributed about the round pipe 3, forming a U-shaped structure. When the round pipe 3 rotates, it will drive the two brackets 9 to rotate synchronously. During the rotation of the square pipe 2, the round pipes 3 at the upper and lower ends alternately exchange positions. When it is at the lower end, cleaning operations are carried out, and when it is at the upper end, air drying operations are carried out.

[0028] A rotating rod 10 is rotatably connected to the support 9. One end of the rotating rod 10 away from the support 9 is fixedly connected to a cross plate 11, and the experimental instrument is positioned between the two cross plates 11. A sliding rod 12 is fixedly connected between the two cross plates 11. There are two sliding rods 12. Both ends of the sliding rod 12 are slidably connected with a slider 13. A spring 14 is arranged between the slider 13 and the corresponding cross plate 11. The spring 14 is sleeved outside the sliding rod 12. One end of the spring 14 is fixedly connected to the slider 13, and the other end of the spring 14 is fixedly connected to the cross plate 11. An arc plate 15 is fixedly connected between the corresponding two sliders 13. The arc plate 15 is of an arc-shaped structure, and the mutually approaching surfaces of the two arc plates 15 are concave surfaces. Specifically, the experimental instrument is inserted between the two arc plates 15, and the spring 14 is compressed to contract. The reset elastic force of the spring 14 enables the experimental instrument to be clamped and positioned between the two arc plates 15.

[0029] A counterweight 16 is fixedly connected to the cross plate 11, and the counterweight 16 is of a trapezoidal structure, and the length of the end away from the cross plate 11 is greater. Specifically, the opening position of the experimental instrument and the position of the counterweight 16 are on the same side of the cross plate 11. During the rotation of the square pipe 2, the circular pipes 3 at the upper and lower ends alternately exchange positions, and the counterweight 16 drives the experimental instrument to flip through structures such as the rotating rod 10, the cross plate 11, and the arc plate 15, so that the opening of the experimental instrument always faces downwards.

[0030] One end of the square pipe 2 away from the rotating shaft 19 is fixedly connected to a rotating pipe 17. The rotating pipe 17 is communicated with the square pipe 2. One end of the rotating pipe 17 away from the square pipe 2 penetrates to the outside of the box body 1. One end of the rotating pipe 17 located outside the box body 1 is communicated with a rotary joint 18, and one end of the rotary joint 18 away from the rotating pipe 17 is communicated with the air supply pipeline of the laboratory. When the square pipe 2 drives the rotating pipe 17 to rotate, the rotary joint 18 can ensure that the air supply pipeline can always supply gas to the square pipe 2. In addition, a heating device can be arranged in cooperation with the air supply pipeline to supply hot air to improve the air drying effect.

[0031] A rotating assembly is arranged at one end of the circular pipe 3 located inside the square pipe 2. The rotating assembly includes a fan blade 8. There are multiple fan blades 8. The fan blade 8 is fixedly connected to the circular pipe 3, and the multiple fan blades 8 are evenly distributed around the circular pipe 3. When the gas enters the inside of the square pipe 2 from the rotating pipe 17, it will drive the circular pipe 3 to rotate through the fan blade 8.

[0032] A circular groove 4 is opened inside the square pipe 2. A circular block 6 is slidably connected inside the circular groove 4. A circular hole 7 is opened inside the circular block 6. A blocking block 5 is fixedly connected inside the circular pipe 3. The blocking block 5 cooperates with the circular hole 7. The width of the blocking block 5 is greater than the diameter of the circular hole 7. When the circular block 6 fits on the blocking block 5, the blocking block 5 can seal the circular hole 7; the width of the blocking block 5 is less than the inner diameter of the circular pipe 3, so that there is a gap between the blocking block 5 and the circular pipe 3. Refer to Figure 4, for the circular tube 3 located at the upper end of the square tube 2, the circular block 6 inside the corresponding circular groove 4 slides downward under the action of gravity, and the gas can blow upward through the circular hole 7, the circular groove 4, and the gap between the baffle 5 and the circular tube 3, blowing into the interior of the experimental instrument and accelerating the drying speed of the experimental instrument; at this time, for the circular tube 3 located at the lower end of the square tube 2, the circular block 6 inside the corresponding circular groove 4 slides downward under the action of gravity, and the circular block 6 fits on the baffle 5, and the baffle 5 can seal the circular hole 7 to prevent the gas from blowing downward to the experimental instrument being cleaned, improving the utilization efficiency of the gas.

[0033] Multiple cleaning components are provided at the bottom of the box body 1, and the cleaning components include support rods 24 and cleaning brushes 25. Both the support rods 24 and the cleaning brushes 25 are provided in multiple numbers, and the cleaning brushes 25 are fixedly connected to the support rods 24.

A support plate 23 is fixedly connected between the two strip plates 22, and the support rods 24 are fixedly connected to the upper surface of the support plate 23. A strip pipe 28 is fixedly connected to the inner wall of the box body 1, the strip pipe 28 is connected to the water supply pipeline of the laboratory, and a nozzle 29 is connected to the strip pipe 28. The nozzles 29 are provided in multiple numbers, and the multiple nozzles 29 correspond to the multiple cleaning brushes 25 one by one.

[0035] A disinfection device 30 is provided inside the box body 1. The disinfection device 30 includes structures such as ultraviolet disinfection lamps and can disinfect the interior of the box body 1 and simultaneously disinfect the experimental instrument.

[0036] During operation, external water source is transported to the strip pipe 28 and sprayed from the nozzles 29 onto the cleaning brushes 25, making the cleaning brushes 25 wet. Start the electric push rod 27 and control the telescopic end of the electric push rod 27 to retract. Drive the cleaning brushes 25 to move upward through the strip plate 22, the support plate 23, and the support rods 24. The cleaning brushes 25 are inserted into the interior of the experimental instrument. After the gas enters the interior of the square tube 2 through the rotating tube 17, it will drive the circular tube 3 to rotate through the fan blade 8, and then drive the experimental instrument to rotate through structures such as the rotating rod 10, the horizontal plate 11, and the arc plate 15. The cleaning brushes 25 cooperate with the nozzles 29 to clean the experimental instrument; After cleaning, the motor 20 rotates to drive the rotating shaft 19 to rotate, and the rotating shaft 19 drives the square tube 2 to rotate, making the cleaned experimental instrument rotate to the upper position. The counterweight block 16 drives the experimental instrument to flip through structures such as the rotating rod 10, the horizontal plate 11, and the arc plate 15, so that the opening of the experimental instrument continues to face downward. At this time, the circular block 6 inside the circular groove 4 slides downward under the action of gravity, and the gas can blow upward through the circular hole 7, the circular groove 4, and the gap between the baffle 5 and the circular tube 3, blowing into the interior of the experimental instrument and accelerating the drying speed of the experimental instrument.

[0037] After the air drying is completed, remove the experimentally-apparatus that has been cleaned, disinfected, and air-dried, and install the experimentally-apparatus to be cleaned to ensure the continuity of cleaning and disinfection.
