Description

Technical Field

[0001] The utility model specifically relates to the technical field of sensors, in particular to a domestic hot water sensor. Background Art

[0002] A temperature sensor is a sensor that can sense temperature and convert it into a usable output signal. Temperature sensors are the core of temperature measuring instruments and come in a wide variety of types. They can be divided into contact and non-contact types based on the measurement method, and into thermal resistors and thermocouples based on the sensor material and electronic component characteristics.

[0003] Chinese patent announcement number CN 214855842 U provides a temperature sensor shell for a tea kettle, including a shell body and a fixing mechanism; a long groove is opened inside the shell body; a fixing ring is fixedly connected to the outer wall of the top end of the shell body; the fixing mechanism is arranged on the inner wall of the fixing ring; the fixing mechanism includes a fixing rod, a fixing block, a first spring and a slider; a first slide groove is opened on the inner wall of the fixing ring; the fixing rod is slidably connected to the inside of the first slide groove; the fixing block is fixed to the end of the fixing rod and is located inside the long groove; the first spring is arranged inside the first slide groove; one end of the first spring is fixedly connected to the bottom of the fixing rod, and the other end is fixedly connected to the bottom of the first slide groove.

[0004] When the temperature sensor housing in the above patent is installed, the bottom of the temperature sensor is inserted into the installation ring in the long groove, so that when the support plate is squeezed, the second spring is compressed by the support plate, and the telescopic rod contracts, so that after the temperature sensor is installed in place, the support plate can play a role of fixing and supporting the temperature sensor due to the recovery effect of the second spring. The above structure is relatively complex and inconvenient to install; and the spring will produce elastic fatigue after long-term use, causing the temperature sensor to become loose during installation, resulting in the inability to continue to use.
