Description

Technical Field

[0001] The utility model relates to the technical field of medicine cabinets, in particular to a portable PP purification box. Background Art

[0002] Medicine cabinets are devices for placing medicines. Medicine cabinets are usually equipped with multiple layers of racks to ensure a larger storage capacity of medicines. Since medicines emit volatile organic compounds (VOC) gases, medicine cabinets need to be equipped with purification boxes to extract and filter the gases in the medicine cabinets to avoid air pollution.

[0003] At present, the commonly used purification method is adsorption, which uses the adsorption effect of activated carbon to purify organic compound gases. In order to ensure the purification effect, other filter plates are set for multiple filtration. However, it is difficult to determine whether the gas discharged from the medicine storage cabinet meets the emission standards. Some organic compound gases without irritating odors are difficult to detect in time if they are not purified. Utility Model Content

[0004] The purpose of the utility model is to provide a portable PP purification box to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solutions: a portable PP purification box, comprising a box body, a hollow bracket is installed inside the box body, a fan is installed in the middle of the hollow bracket, a first VOC sensor is installed on the inner wall of the hollow bracket, and the first VOC sensor is located on the side of the fan;

[0006] Activated carbon filters, wherein a plurality of activated carbon filters are provided and installed at the upper and lower ends of the hollow bracket, the fan is located between two layers of activated carbon filters, and the first VOC sensor is also located between the two layers of activated carbon filters to perform a first detection on the VOC gas discharged from the medicine cabinet;

[0007] A second VOC sensor and a temperature and humidity sensor are installed on the inner wall of the box. The second VOC sensor and the temperature and humidity sensor are located outside the right side of the two layers of activated carbon. The second VOC sensor detects the purified VOC gas. By comparing the detection results of the first VOC sensor and the second VOC sensor, it can be determined whether the activated carbon filter needs to be replaced, and it can be monitored whether the VOC gas is purified to the standard.

[0008] Furthermore, a primary filter is provided at the lower part of the box body, and the primary filter is located below the lower activated carbon filter. The VOC gas is filtered by the primary filter and the two layers of activated carbon filters, thereby improving the purification effect of the VOC gas.

[0009] Furthermore, a support plate is installed on the surface of the box body, and a display controller and a power switch are installed on the surface of the support plate, and the power switch is electrically connected to the fan, and the first VOC sensor, the second VOC sensor, and the temperature and humidity sensor are electrically connected to the display controller. The display controller allows the numerical value of the VOC gas to be visualized for easy viewing. The display controller has an alarm function. When the detection result of the second VOC sensor exceeds a preset value, the display controller alarms through a buzzer.

[0010] Furthermore, a flange pipe is provided on the lower surface of the box body, and the flange pipe is connected to the medicine cabinet, so that the fan can smoothly extract the VOC gas in the medicine cabinet.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The first VOC sensor detects the VOC gas purified by the primary filter and the lower activated carbon filter. If the value of the first VOC sensor exceeds the standard, the display controller will issue an alarm and the lower activated carbon filter and the primary filter will need to be replaced. The second VOC sensor detects the VOC gas content in the air. If the value exceeds the standard, the display controller will also issue an alarm and the upper activated carbon filter will need to be replaced.

[0013] (2) The concentration and temperature and humidity of the VOC gas after being filtered and adsorbed by two layers of activated carbon are monitored by the first VOC sensor, the second VOC sensor, and the temperature and humidity sensor to ensure that the purified VOC gas is clean. The detection results are viewed through the display controller to facilitate the use of the medicine cabinet. BRIEF DESCRIPTION OF THE DRAWINGS
