Example two

In consideration of the fact that the reagent storage device 200 vibrates up and down in the actual operation process of the reagent diagnosis kit in the above embodiment, when the reagent storage device 200 vibrates to the highest point or the lowest point, the spring 320 in the spring telescopic rod 300 generates a resilience force due to deformation, and the plurality of elastic airbags 410 in the vibration damping device 400 are all independent, the middle elastic airbag 410 is squeezed or pulled to the greatest extent when the reagent storage device 200 vibrates, the generated resilience force is greater than that of the elastic airbags 410 at other positions, so that the buffering capacity of the reagent diagnosis kit is weak, and the reagent in the reagent tube 240 in the reagent storage device 200 is prone to generate too severe fluctuation.

As shown in fig. 6, 7 and 8, the damping device 400 further includes a pressure equalizing cavity 420, a liquid storage chamber 430 and an elastic water-stop film 440; the shape of pressure-equalizing cavity 420 is hemisphere, and the concave surface of pressure-equalizing cavity 420 and a plurality of elastic air bags 410 are fixedly connected, and the inside cavity that is provided with of pressure-equalizing cavity 420 communicates with the inside cavity of pressure-equalizing cavity 420 in a plurality of elastic air bags 410 for the inside atmospheric pressure of every elastic air bag 410 is the same.

The liquid storage chamber 430 is positioned below the pressure equalizing cavity 420, the inner space of the liquid storage chamber 430 is cylindrical, and the diameter of the inner space of the liquid storage chamber 430 is the same as the width of the pressure equalizing cavity 420, so that the pressure equalizing cavity 420 can only move up and down in the liquid storage chamber 430; the elastic water-stop film 440 is annular as a whole, the round edge of the inner circle of the elastic water-stop film 440 is fixedly connected with the base 220, and the round edge of the outer circle is fixedly connected with the box body 100 to separate the reagent bin 140 from the liquid storage chamber 430; the liquid storage chamber 430 is filled with aqueous solution, the volume of the aqueous solution in the liquid storage chamber 430 is two thirds of the space of the liquid storage chamber 430, and at the moment, the bottom of the pressure equalizing cavity 420 is positioned in the aqueous solution in the liquid storage chamber 430, so that the reagent storage device 200 is floated and simultaneously vibrated, and a buffer effect is achieved; the elastic water-stop film 440 is made of rubber and plays a role of sealing so that the aqueous solution inside the liquid storage chamber 430 does not flow out.

Preferably, the aqueous solution inside the reservoir 430 is a saline solution.

Further, in case that the reagent storage device 200 vibrates downward, the spring 320 in the spring telescopic rod 300 is compressed, the spring telescopic rod 300 is extended, and the reagent storage device 200 is pulled upward by the spring telescopic rod 300; the elastic air bags 410 in the vibration damping device 400 are squeezed to generate resistance on the reagent storage device 200, at the moment, the middle elastic air bag 410 is squeezed to the maximum extent, and a part of gas in the middle elastic air bag enters the pressure equalizing cavity 420, so that the air pressures of the elastic air bags 410 are the same; at this time, the damper device 400 moves downward, and the portion of the aqueous solution entering the reservoir 430 becomes larger, so that the buoyancy of the aqueous solution to the damper device 400 becomes larger, thereby increasing the damping effect of the damper device 400.

Further, in the case that the reagent storage device 200 vibrates upwards, the spring 320 in the spring telescopic rod 300 is lengthened, the spring telescopic rod 300 is shortened, and the reagent storage device 200 is pushed downwards by the spring telescopic rod 300; the elastic air bags 410 in the vibration damping device 400 are pulled to generate resistance on the reagent storage device 200, at the moment, the pulling degree of the elastic air bag 410 at the middle is the largest, and a part of gas in the pressure equalizing cavity 420 can enter the elastic air bag 410 at the bottom, so that the air pressure of the elastic air bags 410 is the same; the vibration damping device 400 moves upward, and the portion of the aqueous solution entering the reservoir 430 becomes smaller, resulting in that the buoyancy of the aqueous solution to the vibration damping device 400 becomes smaller, thereby increasing the damping effect of the vibration damping device 400.

the vibration reduction device 400 can play a good buffering role on the reagent storage device 200 when the reagent storage device 200 vibrates vertically, so that the vibration of the reagent storage device 200 is softer, and the reagent in the reagent tube 240 in the reagent storage device 200 is not easy to fluctuate too severely.
