Description

Temperature sensor capable of realizing flexible installation Technical Field The utility model relates to the technical field of temperature sensors, in particular to a temperature sensor capable of realizing flexible installation. Background The temperature sensor is suitable for beverage containers such as self-heating cups and intelligent coffee cups which need quick temperature feedback by eliminating a traditional packaging shell and adopting a flexible bending structure to be directly thermally coupled with a cup body, and has at least the following defects in the use process of the traditional NTC probe, namely 1, the traditional NTC probe greatly occupies the space of the cup body in the installation process, such as a hole, a fixed support and the like, thereby influencing the attractiveness and portability, the heat conduction speed is slowed down by a shell body and an internal packaging layer, and the beverage is overheated due to temperature control response delay, and 2, the traditional NTC probe needs to be installed in a way of singly pressing the structure or screwing, so that the production efficiency is reduced. Disclosure of utility model The utility model mainly aims to provide a temperature sensor capable of realizing flexible installation, which can effectively solve the problems in the background technology. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: the utility model provides a can realize flexibly mounted's temperature sensor, includes NTC thermistor, NTC thermistor surface right part has cup jointed pyrocondensation pipe No. one, pyrocondensation pipe left end punch-through fixedly connected with pyrocondensation pipe No. two, NTC thermistor left end fixedly connected with two leads, two the common fixedly connected with connector of lead left end, NTC thermistor surface has paintd the heat conduction silicone grease layer, insulating protection layer has all been paintd to pyrocondensation pipe No. one and pyrocondensation pipe surface No. two, two connectors have been seted up to the connector right-hand member, two the inoxidizing coating has all been paintd to the lead surface. Preferably, both the leads are positioned inside the first heat-shrinkable tube and the second heat-shrinkable tube. By adopting the technical scheme, the welding spots and the thermistor pins are prevented from being shorted together through the first heat shrinkage tube and the second heat shrinkage tube. Preferably, the outer surface of the heat-conducting silicone grease layer is contacted with the inner wall of the first heat-shrinkable tube. By adopting the technical scheme, the response speed of the NTC probe can be greatly shortened after the heat conduction silicone grease is smeared on the outer surface of the NTC thermistor. Preferably, the two leads are respectively in one-to-one correspondence with the two connection ports. Preferably, the two protective layers are contacted with the inner walls of the first heat shrinkage tube and the second heat shrinkage tube. Compared with the prior art, the utility model has the following beneficial effects: 1. By arranging the NTC thermistor and coating a heat conduction silicone grease layer on the outer surface of the NTC thermistor, the installation structure of the traditional NTC probe with a shell is abandoned, so that the physical interlayer of the NTC thermistor and a heat source is changed from an insulating layer, a potting layer, a shell and a glass packaging layer into two layers of an insulating layer and a glass packaging layer, and the response speed of the NTC probe can be greatly shortened after the heat conduction silicone grease is coated in a matched manner (the thermal time constant can be shortened to 0.5s from 3s of the traditional probe); 2.
