A temperature probe having an insulation structure according to an embodiment of the present invention will be described below with reference to fig. 1 to 9, including:
the shell 100 is provided with a first cavity 110 with a downward opening;
the temperature-resistant insulating elastic piece 200 is provided with a second cavity 210 with an upward opening, and the temperature-resistant insulating elastic piece 200 is arranged in the first cavity 110; specifically, the temperature-resistant insulating elastic member 200 may be a bushing made of silicone or plastic and having elasticity. The second cavity 210 may be one of a circular cavity, a polygonal cavity, or an elongated cavity.
An insulating gasket 300, wherein the insulating gasket 300 is disposed on the top of the temperature-resistant insulating elastic member 200, and at least a portion of the insulating gasket 300 is disposed to protrude from the inner sidewall of the second cavity 210;
a temperature sensor 400, wherein the temperature sensor 400 is disposed in the second cavity 210, and a lead end of the temperature sensor 400 abuts against at least a portion of the insulating gasket 300; specifically, the temperature sensor 400 may be a temperature sensor 400 such as a thermocouple sensor, a thermistor sensor, or a resistance temperature detector.
And the pushing piece 500 is used for pushing the pushing piece 500 against the bottom surface of the temperature-resistant insulating elastic piece 200 so as to push the temperature sensor 400 to be tightly attached to the top surface of the first cavity 110. The temperature sensor 400 is used to detect the temperature of the housing 100. The ejector 500 is fixedly connected to the housing 100 by means of snap connection, interference connection or adhesion.
In the embodiment of the present invention, the pushing member 500 pushes the temperature-resistant insulating elastic member 200, so that the temperature-resistant insulating elastic member 200 is deformed by the pushing force, and the bottom of the second cavity 210 protrudes upward to lift the temperature sensor 400 disposed inside the second cavity 210, so that the temperature sensor 400 is tightly attached to the top surface of the first cavity 110, thereby shortening the heat transfer path of the temperature of the housing 100 to the temperature sensor 400, reducing the heat transfer time and heat loss, reducing the heat transfer hysteresis, reducing the heat loss, and being beneficial to shortening the temperature sensing time of the temperature probe and improving the accuracy of the temperature probe.
It should be noted that, when the bottom of the second cavity 210 lifts the temperature sensor 400 due to the pushing force of the pushing member 500, the protruding portion of the insulating spacer 300 relative to the inner sidewall of the second cavity 210 serves as an insulating pressing portion, and abuts against and deforms the lead end of the temperature sensor 400, so that the temperature sensor 400 is not only tightly attached to the top surface of the first cavity 110, thereby shortening the heat transfer path from the temperature of the housing 100 to the temperature sensor 400, but also the leads at the two ends of the temperature sensor 400 do not exceed the second cavity 210 and contact the housing 100 due to the lifting of the temperature sensor 400, thereby effectively solving the problem of the leakage of the temperature sensor 400, and meeting the safety regulations.
In an alternative embodiment, the insulating spacer 300 is ring-shaped, the housing 100 has a mounting groove 111 on an inner wall of the first cavity 110, and an outer circumference of the insulating spacer 300 is embedded in the mounting groove 111.
Specifically, in an embodiment of the present invention, the second cavity 210 is a circular cavity, the insulating spacer 300 is circular, and the middle of the circular insulating spacer 300 has a through hole 310, such that the aperture of the through hole 310 is smaller than the aperture of the second cavity 210, so as to enable the inner wall of the insulating spacer 300 to protrude from the inner wall of the second cavity 210, and at least a portion of the insulating spacer 300 to protrude from the inner wall of the second cavity 210, such that the insulating spacer 300 can abut against the lead terminal of the temperature sensor 400. Further, through seting up mounting groove 111 at the inner wall of first cavity 110, make insulating gasket 300 can fix in first cavity 110, like this when tearing out temperature resistant insulating elastic component 200 after, insulating gasket 300 can also be located first cavity 110 and does not drop to do benefit to dismouting temperature probe.
In an alternative embodiment, at least one of the insulating pads 300 is located beside the lead terminal of the temperature sensor 400, and the sidewall of the insulating pad 300 close to the temperature sensor 400 protrudes from the inner sidewall of the second cavity.
Specifically, as shown in fig. 7, the insulating spacer 300 may be in the shape of a strip or a polygon, and is fixed on the top of the temperature-resistant insulating elastic member 200 by bonding. At least one insulating pad 300 is located beside the lead terminal of the temperature sensor 400, and the sidewall of the insulating pad 300 close to the temperature sensor 400 protrudes out of the inner sidewall of the second cavity, so that at least a portion of the insulating pad 300 protrudes out of the inner wall of the second cavity 210, and the insulating pad 300 can abut against the lead terminal of the temperature sensor 400.
In an alternative embodiment, the temperature-resistant insulating elastic member 200 is provided with at least two first wire outlet holes 220 arranged at intervals, the wire inlet ends of the first wire outlet holes 220 are communicated to the second cavity 210, a lead wire at one end of the temperature sensor 400 passes through one of the first wire outlet holes 220, and a lead wire at the other end of the temperature sensor 400 passes through the other first wire outlet hole 220.
The plurality of first wire outlet holes 220 are not communicated with each other by arranging at least two first wire outlet holes 220 arranged at intervals, a lead at one end of the temperature sensor 400 penetrates out of one first wire outlet hole 220, and a lead at the other end of the temperature sensor 400 penetrates out of the other first wire outlet hole 220, so that the temperature sensor 400 is prevented from being short-circuited due to the fact that leads at two ends of the temperature sensor 400 are in contact. The temperature sensor 400 is prevented from having a leakage risk, and the safety specification is met. Specifically, as shown in fig. 3, in the preferred embodiment, the temperature sensor 400 is horizontally disposed in the second cavity 210, the number of the first wire holes 220 is two, and the distance between the two first wire holes 220 is greater than or equal to the distance between the lead ends at two sides of the temperature sensor 400, so that the first wire holes 220 are located at two sides of the temperature sensor 400, and thus the leads at two ends of the temperature sensor 400 can enter the first wire holes 220 without bending toward the center, thereby avoiding the technical problem that the ejector pushes the temperature-resistant insulating elastic member 200 to break the leads of the temperature sensor 400.
More specifically, in an embodiment of the present invention, the first wire outlet 220 extends downward from the bottom surface of the second cavity 210, and after the leads at the two ends of the temperature sensor 400 pass through the first wire outlet 220, two heat shrinkable tubes are inserted into the first cavity 110 to cover the leads passing through the first wire outlet 220, and the heat shrinkable tubes are heated and shrunk to cover the leads at the two ends of the temperature sensor 400, so as to achieve an insulating effect. Then set up the through wires hole that supplies the both ends lead wire that the cladding has the pyrocondensation pipe to wear out at casing 100, realize that temperature sensor 400's both ends lead wire wears out the external world, avoid temperature sensor 400's both ends lead wire contact casing 100 and have the electric leakage risk, accord with the safety standard.
It should be noted that, the first wire hole 220 is provided in the temperature-resistant insulating elastic member 200, and the temperature-resistant insulating elastic member 200 has an insulating effect, so that a heat shrinkable tube is not required to be sleeved on a lead section penetrating through the first wire hole 220 for insulation, and only the first wire holes 220 arranged at intervals need to be provided, so that the usage amount of the heat shrinkable tube can be reduced, the assembly is convenient, and the production efficiency is improved. In addition, the larger the aperture of the first wire outlet 220 is, the worse the strength of the heat-resistant insulating elastic member 200 in the vertical direction is, so when the pushing member presses against the heat-resistant insulating elastic member 200, the heat-resistant insulating elastic member 200 is easily compressed and distorted, and it is difficult to transmit the pushing force in the vertical direction to the bottom of the second cavity 210 so as to push the temperature sensor 400 to be tightly attached to the top surface of the first cavity 110, therefore, in order to ensure the strength of the heat-resistant insulating elastic member 200 in the vertical direction, the aperture of the first wire outlet 220 should not be too large. The diameter of the lead wires at the two ends sleeved with the heat shrink tube can be increased, which is not beneficial to the lead wires at the two ends to penetrate out of the first wire outlet hole 220. Therefore, in the embodiment, the heat shrink tube is not sleeved on the lead section penetrating through the first wire outlet hole 220 for insulation processing, which not only meets the safety standard, but also facilitates the assembly of the temperature sensor 400 and improves the production efficiency.
In an alternative embodiment, the ejector 500 is provided with at least one second outlet hole 510, and the leads at two ends of the temperature sensor 400 penetrate through the first outlet hole 220 and then are communicated with the outside through the second outlet hole 510.
Specifically, in some embodiments, the number of the second wire outlet holes 510 is one, and the leads at two ends of the temperature sensor 400 penetrate through the first wire outlet hole 220 and then collectively penetrate through one second wire outlet hole 510 to the outside, so that the number of the second wire outlet holes 510 can be reduced, the processing of the ejector is facilitated, and a hole does not need to be formed in the side wall of the housing 100, so as to facilitate the improvement of the strength of the housing 100. It should be noted that, after the ejector pushes the temperature-resistant insulating elastic member 200 and fixes the temperature-resistant insulating elastic member in the first cavity 110, two heat-shrinkable tubes are inserted from the second wire hole 510, and the two heat-shrinkable tubes are sleeved on the two end leads penetrating out from the first wire hole 220 in a one-to-one correspondence manner, so that the two end leads of the temperature sensor 400 are wrapped by the heat-shrinkable tubes, and thus, there is no need to worry about the short-circuit risk existing in the two end leads of the temperature sensor 400 in the same second wire hole 510, so as to meet the safety standard.
In other embodiments, the number of the second wire holes 510 is the same as the number of the first wire holes 220, and the second wire holes 510 are arranged corresponding to the first wire holes 220. Specifically, the first wire outlet hole 220 extends downward from the bottom surface of the second cavity 210, the second wire outlet hole 510 extends downward from the top surface of the ejector, and the wire outlet end of the first wire outlet hole 220 is connected to the wire inlet end of the second wire outlet hole 510. Thus, the leads at the two ends of the temperature sensor 400 penetrate through the first wire outlet 220 and then enter the corresponding second wire outlet 510 to penetrate outside, and there is no need to form a hole on the side wall of the housing 100, which is beneficial to improving the strength of the housing 100.
In an alternative embodiment, the ejector 500 is screwed with the housing 100, the number of the second outlet holes 510 is one, and the second outlet holes 510 are disposed in the middle of the ejector 500.
In this embodiment, the pushing member 500 can slowly push the temperature-resistant insulating elastic member 200 upwards by using a threaded connection manner, so that the temperature sensor 400 can be slowly attached to the top surface of the first cavity 110, which is beneficial to controlling the movement amount of the temperature sensor 400. The technical problem that the temperature sensor 400 is damaged due to overlarge pressure stress during assembly is effectively solved. It should be noted that, when the ejector 500 is fixedly connected to the housing 100 by a threaded connection, the number of the second wire holes 510 is one, and the second wire holes 510 are disposed in the middle of the ejector 500. Thus, the second wire holes 510 are disposed in the middle of the ejector 500, so that the leads at the two ends of the temperature sensor 400 are led out from the two first wire holes 220 and then collected into the same second wire hole 510 to be led out from the outside, thereby preventing the leads at the two ends of the temperature sensor 400 from being twisted when the ejector 500 rotates, and facilitating the assembly and disassembly of the temperature probe structure.
Specifically, the ejector 500 may be screw-coupled to the casing 100 using an internal thread structure, and the ejector 500 may be screw-coupled to the casing 100 using an external thread structure. More specifically, when the ejector 500 is configured with an internal thread, the ejector 500 is a stud, the outer wall of the stud is provided with an external thread, and the inner wall of the first cavity 110 of the housing 100 is provided with an internal thread that is in threaded engagement with the ejector 500. When the ejector 500 has a structure of external thread, the ejector 500 includes an assembling portion 520 and an ejector portion 530, specifically, in a preferred embodiment of the present invention, the assembling portion 520 may be an annular wall surrounding the outer wall of the casing 100, and the ejector portion 530 may be a boss inserted into the first cavity 110 and abutting against the temperature-resistant insulating elastic member 200. The inner wall of the assembling portion 520 is provided with an internal thread, and the outer wall of the housing 100 is provided with an internal thread which is in threaded fit with the assembling portion 520. It should be noted that the assembling portion 520 is provided with an internal thread at a portion higher than the pushing portion 530, so as to prevent the pushing portion 530 from obstructing the tapping of the assembling portion 520, and facilitate the formation of the internal thread on the inner wall of the assembling portion 520. Certainly, in other embodiments, the pushing top 530 may also be a flat plate, specifically, if the pushing top 530 is a flat plate, the bottom surface of the temperature-resistant insulating elastic member 200 penetrates through the first cavity 110, and when the assembling portion 520 is fixedly connected to the housing 100, the flat plate serves as the pushing top 530 to cover the opening of the first cavity 110 and abut against the temperature-resistant insulating elastic member 200, so that the bottom surface of the temperature-resistant insulating elastic member 200 is retracted to the opening of the first cavity 110, and the pushing temperature sensor 400 is abutted against the top surface of the first cavity 110.
In other embodiments, the ejector 500 is fixedly connected to the housing 100 by a snap connection, an interference connection, or an adhesive connection, so that the ejector 500 is fixedly inserted into the first cavity 110 to push the temperature sensor 400 to be tightly attached to the top surface of the first cavity 110, thereby preventing the temperature sensor 400 from being reset due to the backward movement of the ejector 500 caused by a reaction force. So as to ensure that the ejector 500 can shorten the heat transfer path for transferring the temperature of the housing 100 to the temperature sensor 400, reduce the heat transfer time and heat loss, reduce the heat transfer lag, reduce the heat loss, shorten the temperature sensing time of the temperature probe, and improve the accuracy of the temperature probe. Specifically, when the ejector 500 is fixedly connected to the housing 100 in a snap connection, an interference connection, or an adhesion manner, the number of the second wire holes 510 may be the same as the number of the first wire holes 220, and the second wire holes 510 are arranged in a one-to-one correspondence with the first wire holes 220. Specifically, the first wire outlet hole 220 extends downward from the bottom surface of the second cavity 210, the second wire outlet hole 510 extends downward from the top surface of the ejector 500, and the wire outlet end of the first wire outlet hole 220 is connected to the wire inlet end of the second wire outlet hole 510. Thus, the leads at the two ends of the temperature sensor 400 penetrate through the first wire outlet 220 and then enter the corresponding second wire outlet 510 to penetrate outside, so that a hole does not need to be formed in the side wall of the housing 100, which is beneficial to improving the strength of the housing 100.
In an alternative embodiment, a space between the bottom surface of the second cavity 210 and the top surface of the first cavity 110 is filled with a thermally conductive and insulating material 600 in a paste form.
It should be noted that, if the thermal conductive insulating material 600 is a liquid, the liquid insulating material may leak from the wire outlet, and there is a technical problem that the thermal conductive insulating material 600 cannot be fixed between the top of the first cavity 110 and the temperature sensor 400, so that the space between the top of the first cavity 110 and the temperature sensor 400 cannot be filled to empty the air between the top of the first cavity 110 and the temperature sensor 400. If the heat conductive insulating material 600 is solid, since the space between the top of the first cavity 110 and the temperature sensor 400 is changed when the pushing member 500 pushes the temperature-resistant insulating elastic member 200, the solid heat conductive insulating material 600 is difficult to fill the space between the top of the first cavity 110 and the temperature sensor 400, and cannot exhaust the air between the top of the first cavity 110 and the temperature sensor 400.
In this embodiment, the paste-shaped heat conductive insulating material 600 is adopted, when the pushing member 500 pushes the temperature-resistant insulating elastic member 200 upwards, the paste-shaped heat conductive insulating material 600 flows under pressure, the temperature sensor 400 is covered in the second cavity 210, and the air at the top of the first cavity 110 and the air inside the second cavity 210 are removed, so as to prevent the air from reducing the accuracy of the temperature sensor 400. The shape of the heat-conducting insulating material 600 is changed along with the change of the space between the top of the first cavity 110 and the temperature sensor 300, the air at the top of the first cavity 110 and the inside of the second cavity 210 can be exhausted, and the temperature sensor 400 is coated by the heat-conducting insulating material 600, so that the accuracy of the temperature sensor 400 is ensured. More specifically, in a preferred embodiment of the present invention, the thermally conductive and insulating material 600 in the form of a paste is thermally conductive silicone grease.
In an alternative embodiment, the housing 100 includes a connecting portion 120 and a position-limiting portion 130, the position-limiting portion 130 is protruded relative to an outer sidewall of the connecting portion 120, and the position-limiting portion 130 is used for limiting the connecting portion 120 to move up and down.
For better describing the present technical solution, an embodiment in which the temperature probe having the insulating structure is mounted on the panel 700 of the induction cooking appliance is taken as an illustration, but it is not understood and limited that the temperature probe having the insulating structure can be mounted only on the panel 700 of the induction cooking appliance. Specifically, the panel 700 is provided with a mounting hole, the connecting portion 120 is used for being inserted into the mounting hole for fixed connection, and the limiting portion 130 abuts against the top surface or the bottom surface of the panel 700. The connecting portion 120 is a portion inserted into the mounting hole of the panel 700 and an extending portion thereof, and taking the structure shown in fig. 8 and 9 as an example, a portion between two dotted lines is the connecting portion 120, and a portion other than the two dotted lines is the stopper portion 130. It should be noted that, when the position-limiting portion 130 abuts against the bottom surface of the panel 700 to prevent the pot from colliding and damaging the position-limiting portion 130, the position-limiting portion 130 may abut against and be fixed on the bottom surface of the panel 700 by using an adhesive method, so that the position-limiting portion 130 can still limit the connecting portion 120 from moving up and down. More specifically, in the preferred embodiment of the present invention, the position-limiting part 130 is circumferentially disposed on the outer wall of the connecting part 120, and the first cavity 110 is disposed in the connecting part 120.
