Detailed Description

The technical scheme of the utility model is further explained by the specific implementation mode in combination with the attached drawings.

One embodiment of the present application, as shown in figures 1 through 5,

a temperature probe structure 100, comprising: a housing 110 and a temperature sensor 120 disposed inside a mounting cavity 111 of the housing 110; the temperature sensor comprises a temperature sensing body 121 and a power supply lead 122 connected with the temperature sensing body 121; a heat-conducting mounting sleeve 130 is arranged in the mounting cavity 111; a temperature sensing mounting hole 131 is horizontally formed in the top of the heat conducting mounting sleeve 130, and a wrapping part 132 is formed in the heat conducting mounting sleeve 130 in a downward extending manner; the temperature sensor 120 is mounted in the temperature sensing mounting hole 131; the power supply lead 122 is led out from the temperature sensing mounting hole 131 and is wrapped by the wrapping portion 132; the top of the heat-conducting mounting sleeve 130 is attached to the top surface of the mounting cavity 111, so that the temperature sensor 120 can detect the temperature of the top of the mounting cavity 111.

In temperature probe structure 100 heat conduction installation cover 130 can make temperature sensor 120's installation is more convenient, when temperature sensor 120's power supply wire 122 can be effectively protected, temperature sensor 120 can with the installation cavity 111 of casing 110 is hugged closely the installation, thereby makes temperature probe is in practical application, and the structure is more warm long service life, the temperature of the detection pan that again can be real-time accurate.

Specifically, the temperature sensor 120 has different patterns, and the installation embodiment of the heat-conducting installation sleeve 130 also has a difference.

For example, when the temperature is detected, the two ends of the temperature sensing body 121 are both provided with the power supply wires 122 extending outwards; the temperature sensing mounting hole 131 is a through hole structure, the temperature sensing body 121 is horizontally mounted in the temperature sensing mounting hole 131, and the power supply wires 122 at the two ends of the temperature sensing body 121 are respectively led out from the two ends of the temperature sensing mounting hole 131 and are wrapped by wrapping portions 132 arranged at the two sides of the heat conduction mounting sleeve 130.

For example, when one end of the temperature sensing body 121 is extended outward, the power supply lead 122 is provided; at least one end of the temperature sensing mounting hole 131 is provided with an opening, the temperature sensing is mounted in the temperature sensing mounting hole 131, and the power supply wire 122 at one end of the temperature sensing body 121 is led out from the opening of the temperature sensing mounting hole 131 and is wrapped by the wrapping portion 132 provided at a corresponding position. In the temperature sensor 120, only one end of the temperature sensing body 121 is provided with the power supply lead 122, the temperature sensing body 121 may be horizontally installed in the temperature sensing installation hole 131, or may be vertically installed in the temperature sensing installation hole 131, and the power supply lead 122 may be led out from an opening portion at one end of the temperature sensing installation hole 131 to the wrapping portion 132 for wiring, or may be led out from both ends of the temperature sensing installation hole 131 to the wrapping portion 132 provided at both sides for wiring, respectively.

In order to further reduce the hysteresis when the temperature sensor 120 detects the temperature of the housing 110, it is necessary to further eliminate the influence of the structure provided between the temperature sensor 120 and the top surface of the mounting cavity 111, that is, to further improve the temperature transmission efficiency between the temperature sensor 120 and the top surface of the mounting cavity 111; there are many ways to further improve the efficiency of heat transfer between the two,

for example, a hollow portion 133 is disposed at the top of the temperature sensing mounting hole 131; the hollow-out part 133 is filled with a heat conduction material 134; the temperature sensor 120 is mounted against the bottom of the thermally conductive material 134. The heat conductive material 134 can completely exhaust air between the temperature sensor 120 and the top surface of the mounting cavity 111, and the heat conductive material 134 can more quickly and efficiently transfer the temperature of the housing 110 to the temperature sensor 120, so that the temperature detection accuracy of the temperature probe structure 100 is higher and the hysteresis is lower.

For another example, a hollow portion 133 is disposed at the top of the mounting hole; the top of the temperature sensing mounting hole 131 is made of an elastic material; the heat-conducting mounting sleeve 130 is press-mounted in the mounting cavity 111, and the temperature sensor 120 is in contact with the top surface of the mounting cavity 111 at the hollow portion 133. The heat-conducting mounting sleeve 130 is made of an elastic material as a whole, or the top of the temperature-sensing mounting hole 131 is made of an elastic material, when the heat-conducting mounting sleeve 130 is extruded, the top of the temperature-sensing mounting hole 131 deforms, and the top of the temperature sensor 120 partially enters the hollow-out portion 133 and then directly contacts with the top surface of the mounting cavity 111; by utilizing the characteristics of the elastic material, when the temperature sensor 120 is extruded into the hollow-out portion 133, the air in the hollow-out portion 133 is discharged, and other gaps are filled up by the elastic material, so that the detection accuracy and the real-time performance of the temperature sensor 120 can be improved while the temperature sensor 120 is installed in contact with the top surface of the installation cavity 111.

The wrapping portion 132 may be implemented in various ways, and may be a structure integrated with the heat-conducting mounting sleeve 130, or may be a separate part assembled to the heat-conducting mounting sleeve 130. The specific shape of the wrapping portion 132 is various, so that the power supply lead 122 in the mounting cavity 111 can be led out downward, and the power supply lead 122 can be prevented from contacting the mounting cavity 111.

In some embodiments, the wrapping portion 132 is a vertical through hole structure opened in the heat-conducting mounting sleeve 130.

In some embodiments, the wrapping portion 132 of the temperature sensing mounting hole 131 is made of an elastic material; the wrapping portion 132 is a vertical groove structure 135 formed in the side surface of the heat-conducting mounting sleeve 130. When the heat-conducting mounting sleeve 130 is mounted in the mounting cavity 111 by extrusion, two sides of the vertical groove structure 135 made of an elastic material are further bent towards each other, so as to completely wrap the power supply wire 122 located in the vertical groove structure 135.

The bottom of the mounting cavity 111 is detachably plugged and provided with a plugging piece 140; the blocking piece 140 presses and installs the heat-conducting installation sleeve 130 in the installation cavity 111; the blocking member 140 is provided with a wire through hole 141, and the power supply wire 122 sequentially passes through the wrapping portion 132 and the wire through hole 141 to extend to the outside of the housing. The heat-conducting mounting sleeve 130 can be more stably mounted in the mounting cavity 111 through the plugging piece 140, so that the power supply lead 122 of the temperature sensor 120 is more convenient and faster to wire.

Specifically, the blocking piece 140 may be a nut provided with an external thread, the bottom end of the mounting cavity 111 is provided with an internal thread, and the blocking piece 140 is mounted at the bottom of the mounting cavity 111 through thread blocking.

Specifically, the elastic material is rubber or silica gel; the heat-conducting mounting sleeve 130 is made of heat-conducting silica gel; the heat conductive material 134 is a fillable existing material with heat conductive, curing and elastic properties, and may be specifically a heat conductive silicon or silicone adhesive.

The temperature sensor 120 may be a thermistor, and two ends of the temperature sensing body 121 are respectively extended with a power supply wire 122.

The casing 110 is in contact with a heating body including a pot body, the casing 110 needs to transfer temperature to the temperature sensor 120 after being heated, and in order to reduce the hysteresis of detection of the temperature sensor 120, the temperature sensor 120 needs to be attached to the top surface of the installation cavity 111 of the casing 110 as much as possible; the temperature sensor 120 is an electrical component, and although the types and styles of electrical components with temperature detection in the prior art are very various, all the modified electrical components have a temperature sensing body 121 for sensing temperature by contacting with other objects, and the temperature sensing body 121 is further connected with a power supply lead 122; when the temperature sensor 120 is closely attached to the mounting cavity 111, the power supply lead 122 is also easily contacted with the housing 110, and when the temperature of the housing 110 is high, the power supply lead 122 is directly damaged, so that the temperature sensor 120 cannot normally work.

The temperature sensing mounting hole 131 is horizontally arranged on the heat conduction mounting sleeve 130, when the temperature sensor 120 is mounted, the temperature sensing body 121 is inserted into the temperature sensing mounting hole 131 along the horizontal direction, the power supply lead 122 is led out from the opening part of the temperature sensing mounting hole 131, the power supply lead 122 penetrates through the wrapping part 132, and the wrapping part 132 can wrap the power supply lead 122, so that the power supply lead 122 can extend to the lower part of the mounting cavity 111, wiring is more convenient and reasonable, power supply can be avoided from contacting with the shell 110, and the structure stability of the power supply lead 122 is protected.
