Description

Technical Field

[0001] The utility model relates to the technical field of temperature and humidity sensors, in particular to a novel temperature and humidity sensor. Background Art

[0002] The temperature and humidity sensor is a device that measures ambient temperature and humidity and converts these physical quantities into signals that can be read by a microprocessor or electronic device. It is widely used in meteorological observation, agricultural production, industrial automation, warehouse management, laboratory research, smart home and other fields. For example, humidity sensors play a very important role in smart home systems. By monitoring the temperature and humidity in the house, smart home systems can provide a more comfortable and healthy living environment, while also achieving energy savings and optimization.

[0003] For example, a Chinese patent with publication number CN220398609U discloses a temperature and humidity sensor, which includes a temperature and humidity sensor body, a protective plate, an air blower, a display screen, a dust scraper, a control button and an audible and visual alarm. A protective plate is installed on the top of the temperature and humidity sensor body, an air blower is installed on the bottom of the protective plate, a display screen and a control button are embedded on the front surface of the temperature and humidity sensor body, the display screen is located above the control button, an air outlet of the air blower faces the display screen, a dust scraper is installed on the surface of the display screen, an audible and visual alarm is installed on the bottom of the temperature and humidity sensor body, a control host is arranged inside the temperature and humidity sensor body, and the air blower, display screen, dust scraper, control button and audible and visual alarm are all electrically connected to the control host.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] Firstly, in the utility model, by installing a filter at the air inlet of the temperature and humidity sensor body, dust particles in the air can be effectively intercepted to prevent these dust particles from entering the interior of the temperature and humidity sensor body, thereby ensuring the normal operation of the temperature and humidity sensor body and accurate measurement values. A dust sweeping component is installed on the filter, and the dust on the filter can be regularly cleaned by the dust sweeping component and collected by the dust collecting box to ensure normal air intake at the air inlet, thereby ensuring ventilation efficiency.

[0015] Secondly, in the utility model, a push rod is installed on the temperature and humidity sensor body, the push rod is connected to the bent rod, and the dust sweeping assembly is installed on the bent rod, so that the user can push the dust sweeping assembly to make it work at the filter screen, and the user can push the push rod to make the push rod slide on the first fixed rod of the first slide groove, thereby driving the bent rod to move inside the temperature and humidity sensor body, and one side of the bent rod slides on the second fixed rod in the second slide groove on the mesh frame outside the filter screen, so that the dust sweeping assembly can move stably to clean the filter screen, preventing the dust sweeping assembly from deviating during the movement, thereby reducing the cleaning effect of the dust sweeping assembly on the filter screen.
