[0051] By providing a mark cleaning device, water marks on the inner side of the observation window 5 can be avoided to affect the observation effect.

A water pump 18 is fixedly installed on the surface of the water suction pipe 15.

[0057] In the embodiment of the utility model, when in use, the water pump 18 is started, and the water in the water storage tank 26 is pumped into the water storage plate 16 through the water suction pipe 15, and then sprayed out through the atomizing nozzle 17 at the bottom, so that the humidity inside the working chamber 2 is increased;

[0058] By setting up a mist unit, it is convenient to control the internal humidity.

[0059] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment of the utility model, temperature rise and fall devices 28 are provided on the left and right sides of the experimental box body 1, and heat conduction plates 25 are provided in array on the left and right sides of the working chamber 2.

[0060] In the embodiment of the utility model, when in use, the temperature raising and lowering devices 28 on both sides of the experimental box body 1 are started, and then the temperature of the working chamber 2 of the experimental box body 1 is indirectly raised and lowered through the heat conducting plate 25;

[0061] The heat conduction plates 25 are arranged at intervals to conduct heat, thereby preventing water vapor from entering the temperature raising and lowering device 28 and causing damage thereto.

[0062] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment of the utility model, fans 3 are arranged in an array on the surface of the rear side of the working chamber 2, and racks 14 are arranged in an array on the left and right sides of the surface of the working chamber 2.

[0063] In the embodiment of the utility model, when in use, by setting the fan 3, when it is opened, when the water mist and temperature inside the working chamber 2 are too high, the fan 3 is started to blow air outward, so as to blow the residual hot air and water mist inside outward, so as to achieve rapid cooling, thereby making it convenient for the experimenter to take out the experimental equipment, and by setting the placement rack 14, the experimenter will place the placement plate on a suitable placement rack 14 according to the size of the experimental equipment.

[0064] The above embodiment of the utility model provides a moisture-proof and dust-proof high and low temperature humidity test chamber.

[0066] When the humidity is controlled, the water pump 18 is started to pump the water in the water storage tank 26 into the water storage plate 16 through the water suction pipe 15, and then spray it out through the atomizing nozzle 17 at the bottom, so that the humidity inside the working chamber 2 increases;

[0067] When water marks are found on the inner side of the observation window 5, the explosion-proof motor 7 in the protection frame 6 is started to rotate the lifting screw 8, which in turn drives the moving block 9 to move upward, so that the water-cleaning cotton board 10 moves out from the inner side of the pressing plate 12, absorbs the water marks on the inner side of the observation window 5, and then returns to the inner side of the pressing plate 12;

[0068] When the clean water cotton board 10 enters and exits the inner side of the pressing plate 12, the upper end of the pressing plate 12 will be lifted up. Since a traction unit is provided at the lower end of the pressing plate 12, when the pressing plate 12 is lifted up, the traction unit will cause the pressing plate 12 to apply pressure to the surface of the clean water cotton board 10, thereby squeezing out the excess water contained in the clean water cotton board 10, so that the clean water cotton board 10 is kept dry to a certain extent, thereby facilitating the subsequent water absorption and cleaning work, and the squeezed water flows back into the working chamber 2 through the opening at the bottom of the movable groove 27;

[0069] When it is necessary to clean the water accumulated in the working chamber 2, the rotating rod 21 is started to rotate the movable leak plate 22, and then the through holes 24 on the surface of the movable leak plate 22 are aligned with the fixed leak plates 23 on the upper and lower sides of the lower water tank 19 and the through holes 24 on the surface of the supporting leak plate 20, so that the water flowing onto the lower water tank 19 will flow back into the water tank through the through holes 24, thereby avoiding a large amount of water remaining in the working chamber 2.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
