[0002] The central air conditioning thermostat is a control box that manually adjusts the temperature and humidity of the central air conditioner. It is usually installed on the wall of the home. The thermostat uses the sensors installed inside it to sense the indoor temperature and humidity, and automatically adjusts the temperature and humidity to the set mode to make the home more comfortable. The sensor is set to a plug-in type similar to a USB flash drive. Different module sensors can be purchased according to the needs of the family, and it is more convenient to replace the sensor.

[0003] The sensor of the existing module-mounted central air conditioner thermostat is usually fixed to the bottom of the back of the central air conditioner thermostat with multiple screws. When the sensor fails, it is necessary to first remove the central air conditioner thermostat from the wall, and then use tools to loosen the screws fixing the sensor one by one before removing the sensor and replacing it. This operation is very inconvenient and reduces the maintenance efficiency of the central air conditioner thermostat. Utility Model Content
