Description

Technical Field

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

[0002] Outdoor temperature sensors are widely used in various fields, such as meteorology, agriculture, industrial automation, etc. They can monitor and measure outdoor temperature, helping temperature detection personnel to analyze climate change, predict weather, control agricultural irrigation systems, and monitor the operating status of industrial equipment.

[0003] The existing temperature sensors working in outdoor low-temperature environments have a lower surface temperature due to surface frost, which makes the temperature data read by the sensor lower than the actual temperature. It is also easy to block the sensor's vents and cover the sensor's temperature-sensing part, causing problems affecting the normal operation of the sensor. Therefore, an outdoor temperature and humidity sensor with a defrosting mechanism is proposed to provide temperature detection personnel with a set of temperature detection mechanisms that can be defrosted outdoors to ensure the measurement accuracy of the temperature sensor.

[0005] The technical solution adopted by the utility model to solve the technical problem is an outdoor temperature and humidity sensor with a defrosting mechanism, comprising:

[0006] Temperature sensor, used to detect outdoor temperature;

[0007] The defrost component is arranged on the temperature sensor.

[0008] By adopting the above technical solution, the temperature sensor is defrosted through the defrosting component, and a temperature detection mechanism capable of outdoor defrosting is provided to the temperature detection personnel to ensure the measurement accuracy of the temperature sensor, so that the frost on the surface of the temperature sensor can be cleared in time before detection.

[0009] Specifically, the defrosting component includes:

[0010] The air supply part is used to transfer hot air;

[0011] The heating part is connected with the air supply part.

[0013] Specifically, the air supply unit includes:

[0014] A support sleeve connected to the temperature sensor;

[0015] A metal tube connected to the support sleeve;

[0016] A metal ring connected to the metal tube;

[0017] An air outlet is provided on the metal ring;

[0018] An exhaust fan is arranged on the supporting sleeve;

[0019] The air inlet is arranged on the supporting sleeve.

[0020] Specifically, the exhaust fan is fixedly connected to the bottom of the support sleeve, at least one group of metal tubes is provided, and the metal tubes are welded and fixed at equal distances along the circumference of the top of the support sleeve, and the support sleeve and the metal tubes are communicated with each other.

[0021] Specifically, the metal ring is a hollow structure, the metal ring is sleeved on the periphery of the metal tube, the end of the metal tube away from the support sleeve is welded to the metal ring, and the metal tube is communicated with the inner cavity of the metal ring.

[0022] By adopting the above technical solution, based on the interconnected structure between the support sleeve, the metal tube and the metal ring, the wind flow generated by the exhaust fan can flow in the support sleeve, the metal tube and the metal ring, and be discharged from the exhaust port, thereby blowing air to the surface of the temperature sensor.

[0023] Specifically, the heating unit includes:

[0024] A metal heating rod, used for heating the inner cavity of the support sleeve;

[0025] A top plate, connected to the metal heating rod;

[0028] By adopting the above technical solution, the temperature generated by the metal heating rod is quickly exchanged with the air inside the support sleeve through the heat exchange fins.

[0029] The beneficial effects of the utility model are as follows: the defrosting component is used to defrost the temperature sensor, and a temperature detection mechanism capable of outdoor defrosting is provided for temperature detection personnel to ensure the measurement accuracy of the temperature sensor, so that frost on the surface of the temperature sensor can be cleared in time before detection, thereby solving the problem that the existing temperature sensors working in outdoor low-temperature environments, the surface temperature of the sensor is reduced due to surface frost, so that the temperature data read by the sensor is lower than the actual temperature, and the sensor's vents are easily blocked and the temperature-sensing part of the sensor is covered, causing the normal operation of the sensor to be affected.
