Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a humidity monitoring device for environmental protection monitoring. Background Art

[0002] Humidity refers to the amount of water vapor in the air, which has an important impact on air quality. In many places, air humidity changes frequently, causing significant changes in air quality. The impact of humidity on air quality is achieved through the transmission of particulate matter in the air. Water molecules are very small, and they tend to attach to larger particulate matter, such as dust, pollen, bacteria, etc. When the humidity is high, water molecules will more easily attach to these particulate matter, making them heavier and easier to settle. Therefore, in a high humidity environment, particulate matter in the air will gather together, reducing their dispersion in the air, thereby reducing air quality. Secondly, in a high humidity environment, the reproduction of microorganisms such as bacteria and molds is The speed will increase, and these microorganisms will release some substances that are harmful to health, such as bacterial endotoxins, volatile organic compounds, etc., which will aggravate the degree of air pollution. Therefore, maintaining an appropriate humidity range is very important for maintaining good air quality. When protecting the environment, the ambient humidity needs to be strictly tested to avoid the impact of humidity on the environment. During the detection process, traditional humidity monitoring equipment is more sensitive to the placement. Improper placement will cause inaccurate monitoring results. This problem can be solved by active air collection humidity monitoring equipment, but this will cause a large amount of dust and impurities to enter the detection equipment. Although adding filters can block dust and impurities, it also causes the humidity monitoring equipment to need frequent maintenance. Utility Model Content

[0031] The switching structure includes: a switching motor 9, which is fixedly installed inside the upper cover 2, and the lower end of the output shaft of the switching motor 9 is fixedly connected to an adjusting gear 10, a rotating switching wheel 11 is installed inside the side surface of the upper cover 2, and a yielding groove 12 is opened on the upper surface of one end of the switching wheel 11, and a sliding closing rod 13 is installed inside the upper cover 2;

[0032] A gear block is fixedly arranged on the inner surface of the lower end of the switching wheel 11, and the switching wheel 11 is meshed and connected with the adjusting gear 10 through the gear block. The yielding groove 12 is designed to be concave downward in an arc shape. The closing rod 13 and the air inlet 4 are arranged in a one-to-one correspondence, and the upper end of the closing rod 13 penetrates the outer surface of the air inlet 4, and the closing rod 13 and the upper cover 2 are connected by sliding friction. A spring is connected between the closing rod 13 and the upper cover 2, and the lower end of the closing rod 13 is magnetic;

[0033] During normal operation, the air intake motor 7 starts to drive the fan blades 8 to rotate, and the fan blades 8 inject the air filtered by the filter 5 into the interior of the upper cover 2 through the air inlet duct 4. The injected air flows through the humidity sensor 3 and is detected, and finally flows out of the cavity between the base 1 and the upper cover 2 through the air outlet 6. After a preset period of time, the switching motor 9 starts to drive the adjusting gear 10 to rotate, and the adjusting gear 10 drives the yield groove 12 to rotate by engaging with the switching wheel 11. The yield groove 12 rotates to the bottom of another closing rod 13. At this time, the closing rod 13 that the yield groove 12 turns away from slides up with the support of the switching wheel 11 to close the upper air inlet 4, and the closing rod 13 that the yield groove 12 turns to loses the support of the switching wheel 11 and slides down with the support of the spring to release the closure of the upper air inlet 4, thereby realizing the switching of the air inlet 4 for inhaling air. Example

[0034] This embodiment is disclosed on the basis of the embodiment 1: a flow guide mechanism is provided on the side surface of the upper cover 2, and the filter screen 5 is back-blown and cleaned by the flow guide mechanism;

[0035] The flow guiding mechanism includes: a pressure valve 14, which is fixedly mounted at one end of the air outlet 6 facing the outside of the upper cover 2, a flow guiding pipe 15 is provided on the side surface of the upper cover 2, and a sliding closing plate 16 is installed inside the middle section of the flow guiding pipe 15;

[0036] The lower end of the flow guide pipe 15 penetrates the inner surface of the air outlet 6, and the upper end of the flow guide pipe 15 penetrates the inner surface of the air inlet 4;

At this time, the closing plate 16 slides under the pull of the spring to release the closing of the middle section of the guide tube 15. At this time, the airflow discharged from the lower air outlet 6 is blocked by the pressure valve 14 and discharged upward through the guide tube 15 to the upper air inlet 4. Since one end of the upper air inlet 4 is closed by the closing rod 13 at this time, the exhausted air is blown out through the inner side of the filter 5 to achieve backblowing and cleaning of the filter 5. When the closing rod 13 slides down, the closing rod 13 closes the guide tube 15 by repelling the closing plate 16. The airflow pressure discharged from the air outlet 6 is greater than the opening and closing pressure of the pressure valve 14 and is discharged through the pressure valve 14.
