The second cavity 210 may also be an elongated cavity, and when the second cavity 210 is an elongated cavity, the insulating crimping portion 220 may be a convex portion disposed at two ends of the elongated cavity. Specifically, as shown in the embodiment shown in fig. 1, the temperature sensor 300 is horizontally disposed in the second cavity 210, the number of the first wire outlets 230 is two, a lead at one end of the temperature sensor 300 penetrates through one of the first wire outlets 230, and a lead at the other end of the temperature sensor 300 penetrates through the other first wire outlet 230, so as to avoid short circuit of the temperature sensor 300 caused by connection of the leads at the two ends of the temperature sensor 300. And the spacing distance between the two first wire outlet holes 230 is greater than or equal to the distance between the lead ends at the two sides of the temperature sensor 300, so that the first wire outlet holes 230 are located at the two sides of the temperature sensor 300, and thus the leads at the two ends of the temperature sensor 300 can enter the first wire outlet holes 230 without bending towards the center, thereby avoiding the problem that the pushing force pushes the first temperature-resistant insulating elastic body 200 to press off the leads of the temperature sensor 300.
A temperature sensor 300, wherein the temperature sensor 300 is disposed in the second cavity 210, and a lead end of the temperature sensor 300 is abutted against at least a portion of the insulating crimping portion 220; specifically, the temperature sensor 300 may be a temperature sensor 300 such as a thermocouple sensor, a thermistor sensor, or a resistance temperature detector.
A second temperature-resistant insulating elastic body 400, wherein the second temperature-resistant insulating elastic body 400 is arranged in the first cavity 110, and the top surface of the second temperature-resistant insulating elastic body 400 abuts against the bottom surface of the first temperature-resistant insulating elastic body 200; the second temperature-resistant insulating elastic body 400 is provided with at least two second wire outlet holes 410, the bottom of the second temperature-resistant insulating elastic body 400 is provided with an extension portion 430 extending downwards, the second wire outlet holes 410 extend from the top surface of the second temperature-resistant insulating elastic body 400 to the bottom surface of the extension portion 430, and the wire inlet ends of the at least two second wire outlet holes 410 are communicated with the wire outlet end of the first wire outlet hole 230 in a one-to-one correspondence manner; it should be noted that the first temperature-resistant insulating elastic body 200 and the second temperature-resistant insulating elastic member may be elastic bushings made of silicone or plastic.
The ejecting piece 500 is in threaded connection with the shell 100, and the ejecting piece 500 is used for ejecting the second temperature-resistant insulating elastomer 400 so as to eject the temperature sensor 300 to be tightly attached to the top surface of the first cavity 110; the temperature sensor 300 is used to detect the temperature of the housing 100. Specifically, in the embodiment shown in fig. 5 and fig. 6, the pushing member 500 is abutted against the bottom surface of the second temperature-resistant insulating elastic body 400 except the extension portion 430, so as to push the second temperature-resistant insulating elastic body 400. An avoidance hole 510 is formed in the middle of the ejector 500, the extending portion 430 is inserted into the avoidance hole 510, and the bottom surface of the extending portion 430 protrudes out of the bottom surface of the ejector 500 or is flush with the bottom surface of the ejector 500.
It should be noted that the pushing member 500 pushes the second temperature-resistant insulating elastic body 400 and the first temperature-resistant insulating elastic body 200 so that the temperature sensor 300 is tightly attached to the top wall of the first cavity 110. Because assembly errors easily occur in assembly modes such as buckle connection, interference connection or adhesion, the phenomenon that the pushing force of the pushing piece 500 is too large to damage the temperature sensor 300 can occur, and when the assembly errors occur, the movement amount of the temperature sensor 300 cannot be adjusted by the connection modes, so that the production and the assembly of the temperature probe are not facilitated. And this embodiment adopts threaded connection's mode to enable ejector 500 to push up second temperature resistant insulating elastomer 400 and first temperature resistant insulating elastomer 200 slowly, makes temperature sensor 300 hug closely the top surface of first cavity 110 slowly, does benefit to the amount of movement of control temperature sensor 300, for assembly methods such as buckle connection, interference connection or bonding, this embodiment adopts threaded connection's technical scheme can effectively solve the problem that causes temperature sensor 300 compressive stress too big and damage during the equipment because of assembly error. It should be further noted that, the number of the avoiding holes 510 is one, and the avoiding holes 510 are disposed in the middle of the pushing member 500, so that the leads of the temperature sensor 300 are led out from the second wire outlet 410, and then collected in the same avoiding hole 510 and led out from the outside, so as to prevent the leads at two ends of the temperature sensor 300 from being twisted when the pushing member 500 rotates.
In the embodiment of the present invention, the second temperature-resistant insulating elastic body 400 and the first temperature-resistant insulating elastic body 200 are pushed by the pushing member 500 in the first cavity 110, so that the first temperature-resistant insulating elastic body 200 is deformed by the pushing force, and the bottom of the second cavity 210 is raised upward to lift the temperature sensor 300 disposed in the second cavity 210, so that the temperature sensor 300 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 transferred to the temperature sensor 300, reducing the heat transfer time and heat loss, making the heat transfer hysteresis smaller, and reducing the heat loss, which is 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 300 by the pushing force of the pushing member 500, the insulating wire pressing portion 220 protruding from the inner sidewall of the second cavity 210 abuts against and deforms the lead end of the temperature sensor 300, so that the temperature sensor 300 is not only tightly attached to the top surface of the first cavity 110, the heat transfer path for transferring the temperature of the housing 100 to the temperature sensor 300 is shortened, but also the leads at the two ends of the temperature sensor 300 do not exceed the second cavity 210 and contact the housing 100 due to the lifting of the temperature sensor 300, thereby effectively solving the problem of electrical leakage of the temperature sensor 300 and meeting the safety regulations.
Furthermore, the wire inlet ends of the at least two second wire outlet holes 410 are communicated with the wire outlet end of the first wire outlet hole 230 in a one-to-one correspondence manner, so that the lead wires of the temperature sensor 300 can directly enter the second wire outlet holes 410 after penetrating out of the first wire outlet hole 230, the problem that the lead wires of the temperature sensor 300 can enter the second wire outlet holes 410 after being bent between the first temperature-resistant insulating elastic body 200 and the insulating line concentration is avoided, the bending position of the lead wires is prevented from being pressed between the first temperature-resistant insulating elastic body 200 and the second temperature-resistant insulating elastic body 400 by ejection force, and the problem that the lead wires of the temperature sensor 300 are easily broken by the ejection piece 500 is effectively solved. In addition, the lead of the temperature sensor 300 is led out to the outside through the second wire outlet hole 410 and the avoiding hole 510, and a hole does not need to be formed in the side wall of the casing 100, so that the strength of the casing 100 is improved.
The first wire outlet 230 is arranged in the first temperature-resistant insulating elastomer 200, the second mounting hole is arranged in the second temperature-resistant insulating elastomer 400, and the first temperature-resistant insulating elastomer 200 and the second temperature-resistant insulating elastomer 400 have an insulating effect, so that a heat-shrinkable tube does not need to be sleeved on a lead section penetrating through the first wire outlet 230 and the second wire outlet 410 for insulation, and only the first wire outlet 230 and the second wire outlet 410 which are arranged at intervals need to be arranged. Therefore, in the present embodiment, there is no need to sleeve a heat shrinkable tube on the lead wire section passing through the first wire hole 230 and the second wire hole 410 for insulation treatment. Further, by inserting the extending portion 430 into the avoiding hole 510, and the bottom surface of the extending portion 430 protrudes from the bottom surface of the ejector 500 or is flush with the bottom surface of the ejector 500, the lead of the temperature sensor 300 can directly pass through the outside along the second wire outlet 410, so as to avoid the problem that the lead of the temperature sensor 300 is short-circuited due to the existence of the avoiding hole, and avoid the problem of difficult assembly due to the insertion of a heat shrink tube into the housing 100 for insulation treatment. Not only accords with the safety standard, but also facilitates the assembly of the temperature probe.
In an alternative embodiment, the top surface of the second temperature-resistant insulating elastic body 400 is provided with a wire inlet concave portion 420 at the wire inlet end of the second wire outlet hole 410, and the wire outlet end of the first wire outlet hole 230 is communicated with the wire inlet concave portion 420.
As shown in fig. 2, in the embodiment, the wire inlet concave portion 420 is used as a switching port between the first wire outlet hole 230 and the second wire outlet hole 410, so that the lead of the temperature sensor 300 passes through the first wire outlet hole 230 and then bends in the wire inlet concave portion 420 to enter the second wire outlet hole 410, so that the pushing force does not break the lead. Thus, in this embodiment, the second wire outlet 410 may extend downward without being inclined, so as to facilitate the demolding of the second temperature-resistant insulating elastic body 400.
In an alternative embodiment, the ejector 500 includes an ejector 520 and an assembling portion 530, the assembling portion 530 is provided with an internal thread at a portion higher than the ejector 520, and an external thread matching the internal thread is provided on an outer wall of the housing 100.
Specifically, in the preferred embodiment of the present invention, the assembling portion 530 is an annular wall surrounding the outer wall of the casing 100, and the pushing portion 520 is a boss inserted into the first cavity 110 and abutting against the second temperature-resistant insulating elastic body 400. Certainly, in some embodiments, the pushing top portion 520 may also be a flat plate, specifically, if the pushing top portion 520 is a flat plate, the bottom surface of the second temperature-resistant insulating elastic body 400 penetrates through the first cavity 110, and when the assembling portion 530 is fixedly connected to the housing 100, the flat plate serves as the pushing top portion 520 to cover the opening of the first cavity 110 and abut against the second temperature-resistant insulating elastic body 400, so that the bottom surface of the second temperature-resistant insulating elastic body 400 is retracted to the opening of the first cavity 110, and the pushing temperature sensor 300 is close to the top surface of the first cavity 110. It should be noted that the assembling portion 530 is provided with an internal thread at a portion higher than the pushing portion 520, so as to prevent the pushing portion 520 from obstructing the tapping of the assembling portion 530, and facilitate the formation of the internal thread on the inner wall of the assembling portion 530.
In an alternative embodiment, the second cavity 210 is filled with a thermally conductive and insulating material 600 in the form of a paste.
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 300, so that the space between the top of the first cavity 110 and the temperature sensor 300 cannot be filled to empty the air between the top of the first cavity 110 and the temperature sensor 300. If the heat conductive insulating material 600 is solid, since the space between the top of the first cavity 110 and the temperature sensor 300 is changed when the pushing member 500 pushes the first temperature-resistant insulating elastic body 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 300, and cannot evacuate the air between the top of the first cavity 110 and the temperature sensor 300.
In this embodiment, the paste-shaped heat conductive and insulating material 600 is used, when the pushing member 500 pushes the first temperature-resistant insulating elastic body 200 upwards, the paste-shaped heat conductive and insulating material 600 flows under pressure, the second cavity 210 covers the temperature sensor 300, and the air in the top of the first cavity 110 and the inside of the second cavity 210 is removed, so as to prevent the air from reducing the accuracy of the temperature sensor 300. 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 300 is coated by the heat-conducting insulating material 600, so that the accuracy of the temperature sensor 300 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 optional embodiment, the housing 100 further 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.

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 extended portion thereof, and taking the structure shown in fig. 5 and 6 as an example, the portion between two dotted lines is the connecting portion 120, and the 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.
In an alternative embodiment, the position-limiting surface of the position-limiting part 130 is provided with a sealing filling groove 131, and the sealing filling groove 131 is used for filling a sealing material.
It should be noted that the limiting surface is a surface where the limiting portion 130 abuts against the panel 700, for example, when the limiting portion 130 abuts against the top surface of the panel 700, the limiting surface is a bottom surface of the limiting portion 130; when the position-limiting portion 130 abuts against the bottom surface of the panel 700, the position-limiting surface is the top surface of the position-limiting portion 130. By opening the sealing filling groove 131 on the limiting surface of the limiting portion 130, a sealing material, specifically, a sealing ring or a sealing gasket, can be filled in the sealing filling groove 131, so as to prevent water drops falling to the panel during cooking from flowing into the cooking appliance from the gap between the mounting hole and the connecting portion 120, and damage to the internal circuit is prevented. More preferably, sealing material chooses the sealed material of silicone for use, not only can play the bonding effect to realize the bonding between spacing portion 130 and the panel, can also play waterproof leak protection's effect, prevent to drop to the water droplet of panel in the culinary art process and flow into to cooking utensil's inside from the clearance between mounting hole and the connecting portion 120, cause the internal circuit to damage.
