A support structure for insulating and encapsulating a temperature sensing head

Abstract

The invention relates to the technical field of thermosensitive sensing devices, and specifically relates to a temperature sensing head insulation package support structure. The temperature sensing head insulation package support structure comprises a body with a certain length, wherein the body is provided with N partition plates, N is an even number which is greater than 3, the N partition plates are arranged at equal angles in a spacing mode along the periphery of the body, the outer end of each partition plate is provided with two support pieces, and the two support pieces symmetrically extend towards two sides of the partition plate and thus form a Y-shaped integrated structure with the corresponding partition plate. The temperature sensing head insulation package support structure isreasonable in structure, welding spots of a thermistor are arranged between the partition plates, and the snowflake-shaped distributed partition plates and the support pieces perform clamping and positioning on the welding spots, so that the distance between the welding spots and a sensing head is effectively guaranteed, and the symmetric support structure enables the thermistor and the welding spots to be arranged at the middle of the sensor, thereby ensuring the electrical insulation of the sensor, being convenient for subsequent injection of a sealant, and also being capable of reducing the consumption of the sealant and improving the curing efficiency.

Description

Technical field [0001] The invention relates to the technical field of thermal sensing devices, in particular to an insulating packaging support structure for a thermal sensing head. Background technique [0002] With the rise of smart home appliances, electric heating appliances are generally equipped with various sensors and micro-processing terminals, so as to realize the purpose of self-regulating heat and controlling cooking procedures. The temperature sensor is the core of intelligent control. The temperature sensor used in electric heating appliances is generally a top temperature probe, which can sense the heat and cooking progress through direct contact. It mostly uses a temperature-sensitive metal shell and thermistor built-in structure. Thermistor The lead wires are led out from the opening of the shell and insulated with sealant. [0003] Since the temperature probe needs to be exposed to water vapor, and its temperature-sensing shell needs to meet the requirements of ...

Problems solved by technology

[0003] Since the temperature-sensing probe needs to be exposed to water vapor, its temperature-sensing shell needs to meet the requirements of food safety standards, so it is mostly made of sus304 stainless steel or aluminum, and the cost is relatively high

With the development of temperature sensing technology, in order to adapt to the overall design of the electric heating capacitor, the product structure is getting smaller and smaller, and the complex shape processing of the metal probe is becoming more and more difficult; the pins of the thermistor need to be soldered and inserted The temperature probe, its welding part is close to the metal shell, resulting in insufficient insulation, the lead wire is embedded in the insulating glue with less depth and lacks a fixed structure, and the electrical safety protection is insufficient
