[0002] Humidity chambers are often used in laboratories to test the humidity of experimental items. Humidity chambers are equipment for calibrating the indication of hygrometers, also known as humidity calibration chambers. The purpose of humidity control is to adjust the water content of the air in a specific space. The device is highly modernized, and the humidification, dehumidification and stabilization processes in the humidity chamber are all achieved through program settings. From data collection to the processing of calibration results, everything can be completed automatically, thereby greatly improving the precision and accuracy of humidity instrument calibration.

[0003] After searching, for example, a temperature and humidity calibration box is provided by the Chinese utility model patent publication number CN220490107U. Through relevant settings, the device can evenly inject moisture into the upper cavity to evenly humidify the upper cavity. However, the device has defects. Its disadvantage is that after the calibration, the device will condense into water droplets inside due to the increase in humidity. Since the device is not equipped with a cleaning component, manual cleaning is required. Therefore, a laboratory adjustable humidity box is proposed to solve the above problem. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 In this embodiment, an adjustable humidity chamber for a laboratory includes an upper box body 1, a partition 2 is fixedly installed on the bottom of the upper box body 1, a lower box body 3 is fixedly installed on the bottom of the partition 2, and a cleaning component 11 is provided inside the upper box body 1.

[0021] The cleaning assembly 11 includes two electric telescopic rods 111, which are fixedly mounted on the inner left wall of the upper box body 1. A dust collection cleaning plate 112 is fixedly mounted on the right side of the two electric telescopic rods 111, and two dust collection heads 113 are fixedly mounted on the right side of the dust collection cleaning plate 112. Absorbent cotton 114 is bonded to the outer walls of the dust collection cleaning plate 112. A dust removal box 115 is fixedly mounted on the left outer surface of the upper box body 1, and a dust collection fan 118 and a filter plate 117 are installed inside the dust collection box 115.

[0022] like Figure 1 As shown, the humidification process is to first start the ultrasonic atomizer 5, which atomizes the water inside the water tank 4, and then start the heating wire to increase the temperature inside the water tank 4, thereby increasing the rate of molecular movement, so that the atomized water vapor produces a hot air flow effect, and then enters the interior of the spray plate 8 through the delivery pipe 6, and then is sprayed out through the nozzle 9, thereby achieving the purpose of humidification, and then the water vapor delivery rate is adjusted by the control of the solenoid valve 7, so as to achieve the purpose of uniform water vapor delivery.

[0023] like Figure 1 and Figure 2 As shown, by setting up a control panel, and the control panel is electrically connected to the humidity sensor, solenoid valve 7, etc. through wires, the solenoid valve 7 can be controlled by the control panel to control the water vapor transmission rate, and by setting up the humidity sensor, the humidity inside the device can be monitored in real time.

[0024] like Figure 1 As shown, a placement component 10 is set up, and the placement component 10 includes a water accumulation platform 101 and a porous placement plate 102. When in use, the object to be tested is placed on the top of the porous placement plate 102, and then as the humidity increases, the water droplets condensed on its surface will fall through the holes into the interior of the water accumulation platform 101.

[0025] like Figure 1 and Figure 4 As shown, the vacuum cleaning plate 112 is hollow and an opening is provided inside the vacuum cleaning plate 112. The opening can prevent the movement of the vacuum cleaning plate 112 from affecting the use of the placement component 10, and absorbent cotton 114 is adhered to the outer wall around it. The absorbent cotton 114 fits tightly with the inner wall of the device, which can achieve the effect of cleaning the inner wall around the device.

[0026] like Figure 1 and Figure 3 As shown, a dust suction hose 116 is provided, and both ends of the dust suction hose 116 can extend to the inside of the dust removal box 115 and the upper box body 1 respectively, so that dust can be easily sucked onto the filter plate 117 through the dust suction hose 116.

[0027] like Figure 3 As shown, by setting up an air duct, the interior of the dust removal box 115 can be exhausted, and by setting up an installation slot, the filter plate 117 can be conveniently connected to the interior of the dust removal box 115, and a baffle is provided on the surface of the dust removal box 115. By opening the baffle, the filter plate 117 can be taken out and cleaned.

[0028] During implementation, follow these steps:

[0029] 1) First open the door of the upper box 1;

[0030] 2) The object to be tested is then placed on top of the porous placement plate 102;

[0031] 3) The ultrasonic atomizer 5 is started again to atomize the water in the water tank 4, and the heating wire is started at the same time, so that the atomized water vapor can generate a hot air flow effect, enter the spray plate 8 through the delivery pipe 6, and then be sprayed out through the nozzle 9;

[0032] 4) By regulating the solenoid valve 7, the moisture delivery is adjusted to ensure the uniformity of the internal humidity;

[0033] 5) After the final inspection is completed, the interior of the upper box body 1 is cleaned by the cleaning component 11.

[0034] To sum up, the adjustable humidity box of the laboratory is provided with a cleaning component 11. After the device is calibrated, the electric telescopic rod 111 is started. The electric telescopic rod 111 drives the absorbent cotton 114 to absorb water from the inner wall of the device by driving the movement of the dust cleaning plate 112, thereby cleaning the water droplets on the inner wall of the device. At the same time, the dust suction fan 118 can be started. The dust suction fan 118 sucks the dust onto the filter plate 117 through the cooperation of the dust suction hose 116 and the dust suction head 113, thereby cleaning the dust inside the device. Through the above-mentioned arrangement, not only the water droplets condensed inside the device can be cleaned, but also the dust inside the device can be cleaned, thereby saving labor and improving work efficiency.
