Due to the flow barrier of the guide plate and the inverted plate, the water vapor is reduced from directly entering the detection cavity through the top of the annular partition. When the air is gathered in large quantities at the top of the annular partition, part of the water vapor it carries will form water droplets on the top surface of the protective shell and flow down from the slits of the support frame. Some of the water droplets are guided on the triangular guide plate and enter the guide cavity through the guide port on the front side of the inclined guide plate and flow out from the flow hole, thereby preventing water vapor from accumulating in the detection cavity and affecting the normal operation of the temperature sensor. The temperature sensor can be kept dry during operation, thereby reducing the aging of parts and increasing its service life.
