Description
Technical Field
The utility model relates to a temperature sensor technical field, especially an embedded temperature sensor.
Background
The temperature sensor is a sensor which can sense temperature and convert the temperature into a usable output signal, in the prior art, when the temperature of a heating plate of an electric cooker or an electric kettle is detected, the temperature sensor is usually abutted against the heating plate, but the arrangement has the defects that the sensor is only partially contacted with the heating plate, the temperature sensing is not accurate enough, and the sensor part is also contacted with air to generate heat transfer, so that the detected temperature value is generally low.
Disclosure of Invention
To the problem that exists among the prior art, the utility model aims to provide an embedded temperature sensor.
In order to solve the above problems, the utility model adopts the following technical proposal.
The utility model provides an embedded temperature sensor, includes the protective housing, be provided with thermistor in the protective housing, the one end that thermistor was kept away from to the protective housing is provided with the screw, thermistor electric connection has the lead wire, and this lead wire passes protective housing and screw in proper order, and this screw can screw in the internal thread that outside heating coil bottom set up so that the protective housing can imbed to the outside in the dish that generates heat.
As a further improvement of the present invention, the lead wire is electrically connected to the connector.
As a further improvement of the utility model, the protective housing is filled with resin, the resin is wrapping up the thermistor.
As a further improvement of the utility model, be provided with the sealing washer between protective housing and the screw.
As a further improvement of the utility model, the lead wire is wrapped with a first heat-shrinkable sleeve.
The beneficial effects of the utility model
Compared with the prior art, the utility model has the advantages of:
the utility model discloses a screw imbeds thermistor completely to the dish that generates heat in, and the temperature value that thermistor detected is exactly the actual temperature value of the dish that generates heat, and temperature sensing is accurate reliable.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiment of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention based on the embodiments of the present invention.
Referring to fig. 1, an embedded temperature sensor includes a protective housing 2, a thermistor 1 is disposed in the protective housing 2, a screw 5 is disposed at one end of the protective housing 2 away from the thermistor 1, the thermistor 1 is electrically connected to a lead 8, the lead 8 sequentially penetrates through the protective housing 2 and the screw 5, and the screw 5 can be screwed into an internal thread disposed at the bottom of an external heating disc so that the protective housing 2 can be embedded into the external heating disc. The dish bottom that generates heat is provided with the appearance chamber that can hold protective housing 2 and supplies screw 5 precession protective housing 2 inside internal thread, the utility model discloses a screw 5 imbeds thermistor 1 completely to the dish that generates heat in, and the temperature value that thermistor 1 detected is exactly the actual temperature value of the dish that generates heat, and temperature sensing is accurate reliable.
Further, the lead 8 is electrically connected with a connector 9 for connecting with an external detection and analysis device.
Further, the protective housing 2 is filled with resin 3, the thermistor 1 is wrapped by the resin 3, and the resin 3 plays a role in protecting and conducting heat to the thermistor 1 and can also avoid rigid collision between the thermistor 1 and the housing.
In order to prevent from being thermally conducted with the outside, the temperature value detected by the thermistor 1 is more accurate, a sealing ring 4 is arranged between the protective shell 2 and the screw 5, the sealing ring 4 is used for sealing the containing cavity of the heating disc, and the temperature in the containing cavity and the heat conduction between the outside are isolated.
The lead 8 is wrapped with a first heat-shrinkable sleeve 7. The heat-shrinkable sleeve has the technical effects of high-temperature shrinkage, softness, flame retardance, insulation, corrosion prevention and the like. In the design, the connector 9 is wrapped with a second heat-shrinkable sleeve 10, and the connection between the leads is connected by an old copper strip 6.
The above description is only the preferred embodiment of the present invention; the scope of the present invention is not limited thereto. Any person skilled in the art should also be able to cover the technical scope of the present invention by replacing or changing the technical solution and the improvement concept of the present invention with equivalents and modifications within the technical scope of the present invention.
