Description

Technical Field

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

[0002] Temperature and humidity sensors mostly use integrated temperature and humidity probes as temperature measuring elements, collect temperature and humidity signals, and convert them into current or voltage signals that are linearly related to temperature and humidity after voltage stabilization and filtering, operational amplification, nonlinear correction, V / I conversion, constant current, and reverse protection circuit processing. They can also be directly output through 485 or 232 interfaces through the main control chip. Most of the temperature and humidity sensors currently used are fixed installations.

[0003] According to the Chinese patent with the announcement number "CN117824751A", a new type of temperature and humidity sensor is disclosed, including a temperature and humidity sensor body, one end of the temperature and humidity sensor body is fixedly connected to an antenna, and a sensor probe is fixedly connected to one side of the lower end of the temperature and humidity sensor body. A ventilation window is provided on the inner sleeve of the sensor and a dustproof net is installed on it. Air can enter the inner sleeve of the sensor to contact the sensor probe and block dust in the air from entering. When cleaning the dustproof net, a push plate is pushed by a push rod, and the push plate slides in a slide groove on the outer sleeve of the sensor. The push plate drives the mounting ring to slide on the outer sleeve of the sensor. The wiping pad on the inner wall of the mounting ring moves back and forth up and down, which can effectively clean the four dustproof nets and prevent the dustproof nets from being blocked and affecting the sensitivity of the sensor probe. Through these improvement measures, the influence of the vent blockage on the sensitivity of the sensor probe can be effectively reduced, ensuring the normal operation and accurate monitoring of the temperature and humidity sensor.

[0004] It can be known from the above structure that a dust screen is installed on the air vent window provided on the inner sleeve of the sensor, so that air can enter the inner sleeve of the sensor to contact the sensor probe and block the dust in the air from entering. When cleaning the dust screen, the push plate is pushed by the push rod, and the push plate slides in the slide groove on the outer sleeve of the sensor, and the push plate drives the mounting ring to slide on the outer sleeve of the sensor, and the wiping pad on the inner wall of the mounting ring is moved up and down reciprocatingly, so as to effectively clean the four dust screens and prevent the dust screens from being blocked and affecting the sensitivity of the sensor probe. Through these improvement measures, the influence of the blockage of the ventilation holes on the sensitivity of the sensor probe can be effectively reduced, so as to ensure the normal operation and accurate monitoring of the temperature and humidity sensor. Although the above structure achieves the effect of cleaning dust, most of the receiving antennas on the existing temperature and humidity sensors are directly fixed on the temperature and humidity sensors, and the extended receiving antennas are exposed to the outside and are likely to cause scratches and damage. At the same time, during use, when the receiving antenna on the temperature and humidity sensor is impacted, it is easy to be damaged, thereby affecting the normal use of the temperature and humidity sensor in the later stage.
