Problems solved by technology
The temperature sensor under this framework has a long thermal equilibrium time during the temperature measurement process, (armpit temperature measurement) generally takes 5 minutes or even longer, and the temperature measurement efficiency and accuracy are low, especially in the body surface (forehead) temperature measurement scene. The temperature value obtained is generally lower than the actual temperature of the body surface
In addition, under this framework, the manufacturing process and testing process are complex and cumbersome, and the cost is high

Abstract
The invention relates to a temperature sensing assembly, a manufacturing method thereof, and a thermometer. The temperature sensing assembly comprises a heat conduction piece, a thermosensitive piece and a circuit board, the heat conduction piece is sealed on the circuit board, the thermosensitive piece is packaged between the heat conduction piece and the circuit board, the circuit board is provided with a blind hole whose size is larger than that of the thermosensitive piece, one side of the thermosensitive piece is in contact with the heat conduction piece, the other side of the thermosensitive piece is arranged in the blind hole, a heat insulation layer is formed between the thermosensitive piece and the inner wall of the blind hole in a spaced mode, and the thermosensitive piece is electrically connected with the circuit board. In terms of mechanical structure and circuit connection, through one-time operation of the sealing process, the purposes of electrical connection between the thermosensitive piece and the circuit board and airtight and watertight packaging between the heat conduction piece and the circuit board can be achieved at the same time, the process is effectively simplified, and the cost is reduced.
Description
technical field [0001] The present invention generally relates to the technical field of temperature measurement. More specifically, the present invention relates to a temperature sensing component, a manufacturing method thereof, and a thermometer. Background technique [0002] Traditional temperature sensors, especially armpit thermometers and temperature sensors on body surface (such as forehead) temperature measuring stickers, generally use stainless steel caps or stainless steel planes as heat conduction layers, and install thermistors inside or on the other side as temperature sensors. layer, and then fill the space around the thermistor with heat-conducting silicone grease and other materials to connect the temperature-sensing layer to the heat-conducting layer, and finally connect the thermistor to the detection chip, and the chip collects the thermistor value and converts it into a temperature value. The temperature sensor under this framework has a long thermal eq...
