Thermohygrometer is a precision measuring device used to monitor the temperature and humidity in the environment in real time. It consists of a temperature sensor and a humidity sensor, which can accurately measure and display the temperature and humidity data of the environment.

[0003] In the prior art, in order to more conveniently observe and record the temperature and humidity data in the environment, digital thermometers and hygrometers are mostly used to detect the current environment. However, during the use of digital thermometers and hygrometers, since the internal temperature and humidity sensors need to be in contact with the air of the detection environment, after long-term use, dust in the air will scatter and accumulate on the surface of the sensor, causing its detection accuracy to deteriorate or even fail. In addition, since the sensor is inside the thermometer and hygrometer, it is not easy to clean, and the accumulation of dust on the surface will affect the detection of temperature and humidity. Therefore, it is necessary to propose a digital thermometer and hygrometer to solve the above-mentioned problems. Utility Model Content

The dust removal block is driven to move horizontally by rotating the threaded transmission rod, and the cleaning strip on the surface of the dust removal block cleans the dust on the sensor surface.

[0009] Furthermore, in order to remove the dust that falls during cleaning from the protective shell, a cleaning shovel is fixedly installed at the bottom of the dust removal block, and a cleaning port is opened on the outer wall of one side of the protective shell.
