[0038] This invention provides a heating element temperature measuring device, comprising a support assembly, a mounting assembly, and a temperature sensor. The support assembly is a cylindrical structure, and its diameter is not greater than the aperture of the heating cavity of the heating appliance. The mounting assembly includes a pull rod and a guide. The pull rod is slidably disposed on the support assembly and can slide radially or parallel to the radial direction of the support assembly. The guide is movably disposed on the pull rod and can move axially along the support assembly. The temperature sensor is disposed on the guide. The support assembly extends into the heating cavity of the heating appliance, providing support for the overall structure. The mounting assembly allows the temperature sensor to move radially via the pull rod and axially via the guide, enabling more flexible adjustment of the temperature sensor's position and ensuring contact with the heating element for accurate temperature measurement. The heating element temperature measuring device can measure the surface temperature of the heating element without disassembling the heating appliance, thus protecting the overall structure of the heating appliance.

[0039] Please refer to the following: Figs. 1 to 3 In one embodiment, a heating element temperature measuring device 100 is provided, which is mainly used to measure the temperature of the surface of the heating element 200 in the heating appliance.

[0040] The heating element temperature measuring device 100 includes a support assembly 10, a mounting assembly 20, and a temperature sensor 30. The support assembly 10 is mainly used to extend into the heating chamber of the heating appliance and abut against the appliance; the support assembly 10 is the main support structure of the entire device. The mounting assembly 20 is used to install the temperature sensor 30, which is mainly used to measure the temperature of the heating element 200.

[0041] The support component 10 has a cylindrical structure, and its diameter is not greater than the aperture of the heating cavity of the heating appliance. In other words, the diameter of the support component 10 is less than or equal to the aperture of the heating cavity, so that when the heating element temperature measuring device 100 is in use, the support component 10 can be smoothly inserted into the heating cavity, allowing it to abut against the inner wall of the heating cavity.

[0042] The mounting assembly 20 includes a pull rod 21 and a guide member 22. The pull rod 21 is slidably disposed on the support assembly 10 and can slide radially or parallel to the support assembly 10. The guide member 22 is movably disposed on the pull rod 21 and can move axially along the support assembly 10. The temperature sensor 30 is disposed on the guide member 22. In other words, the mounting assembly 20 has at least two movable components with different directions of movement. The pull rod 21 can slide radially or parallel to the support assembly 10, while the guide member 22 can move axially along the support assembly 10. Furthermore, since the temperature sensor 30 is disposed on the guide member 22, the radial and axial positions of the temperature sensor 30 can be flexibly adjusted by sliding the pull rod 21 and moving the guide member 22, ensuring that the temperature sensor 30 can be moved to a position in contact with the heating element 200.

[0043] Understandably, in the existing technology, measuring the temperature of the heating element surface requires disassembling the heating appliance, which can damage the appliance and affect its subsequent use.

[0044] The heating element temperature measuring device 100 provided in this embodiment can be directly inserted into the heating cavity through the support component 10 during temperature measurement. Then, the position of the temperature sensor 30 is adjusted by the mounting component 20 so that the temperature sensor 30 contacts the surface of the heating element 200, thereby measuring the surface temperature of the heating element 200. The temperature measuring device does not need to be held by hand during the measurement process, making it compact and convenient. The heating element temperature measuring device 100 can measure the surface temperature of the heating element 200 without disassembling the heating appliance, protecting the overall structure of the heating appliance. Furthermore, the mounting component 20 allows for more flexible and precise adjustment of the position of the temperature sensor 30, ensuring that the temperature sensor 30 can contact the heating element 200, ensuring the accuracy of the temperature measurement, and also allowing the temperature sensor 30 to perform multi-point measurements of the heating element 200. In addition, it is understood that since the position of the temperature sensor 30 can be flexibly adjusted through the mounting component 20, the heating element temperature measuring device 100 can also be adapted to different types of heating appliances for temperature measurement.

[0045] Preferably, in one embodiment, the guide member 22 is a hollow structure, with one end of the guide member 22 located outside the support assembly 10 and the other end extending into the support assembly 10. The temperature sensor 30 passes through the guide member 22, and the temperature probe of the temperature sensor 30 extends outside the guide member 22 and is located within the support assembly 10. This structure provides better protection for the temperature sensor 30. Specifically, the guide member 22 is made of a rigid material. By wrapping the temperature sensor 30 with a rigid material, the position of the temperature sensor 30 can be prevented from changing during the positioning process.

[0046] Preferably, in one embodiment, the guide member 22 is engaged with the pull rod 21, and the outer surface of the guide member 22 is provided with multiple locking positions 221. Along the axial direction of the guide member 22, one locking position 221 is provided at 1mm intervals. By providing one locking position 221 at 1mm intervals, the vertical movement distance of the guide member 22 is more precise and controllable.

[0047] Specifically, in one embodiment, the locking position 221 of the guide member 22 can be made of an elastic material (such as an elastic rubber ring), so that when the position of the guide member 22 needs to be adjusted, the locking position 221 can be deformed by manual force, allowing the guide member 22 to move smoothly up and down. When the adjustment is complete and no force is applied, other locking positions 221 can be used to lock onto the pull rod 21 to restrict the position of the guide member 22. Of course, in other embodiments, the position on the pull rod 21 that contacts the locking position 221 can be made of an elastic material, while the locking position 221 can be made of a rigid material. It is even possible that both the position on the pull rod 21 that contacts the locking position 221 can be made of an elastic material. That is to say, the guide member 22 can be stably fixed on the pull rod 21 without force; and when adjustment is needed, the position of the guide member 22 can be smoothly adjusted by applying force.

[0048] Preferably, in one embodiment, the support assembly 10 is a hollow cylindrical structure with one open end, the guide member 22 extends into the interior of the support assembly 10, and the temperature probe of the temperature sensor 30 is located inside the support assembly 10. The support assembly 10 includes a top wall 11 and a side wall 12 connected to the top wall 11, and the pull rod 21 is movably disposed on the top wall 11. That is, in this embodiment, the heating element temperature measuring device 100 is mainly used to measure the temperature of a center-heated smoke appliance. When the support assembly 10 is inserted into the heating chamber, the heating element 200 is correspondingly inserted into the support assembly 10, thereby measuring the temperature of the heating element 200 through the temperature probe of the temperature sensor 30 located in the internal region of the support assembly 10.

[0049] Preferably, in one embodiment, the sidewall 12 includes a support body 121 and a base 122. The support body 121 is connected to the top wall 11, and the base 122 is disposed at the bottom of the support body 121. The base 122 is mainly used to abut against the inner bottom wall of the heating chamber.

[0050] More preferably, in one embodiment, the support 121 is a telescopic structure. That is, the support 121 is a telescopic tubular structure. By setting the support 121 as a telescopic structure, the overall height of the support assembly 10 can be adjusted according to actual needs, and the support assembly 10 can be adapted to heating cavities of different depths for use.

[0051] More preferably, in one embodiment, the bottom of the base 122 is provided with wear-resistant and high-temperature-resistant contact feet 1221. That is, the base 122 contacts the inner bottom wall of the heating chamber through the contact feet 1221 located at the bottom, and the contact feet 1221 are made of a high-temperature-resistant material with a high coefficient of friction. Specifically, in one embodiment, the contact feet 1221 are made of rubber, and the contact feet 1221 are rubber contact feet. Specifically, in one embodiment, multiple contact feet 1221 are provided.

[0052] Preferably, in one embodiment, a slide rail 111 is provided on the top wall 11, and the pull rod 21 is slidably disposed on the slide rail 111. The slide rail 111 guides the sliding position of the pull rod 21 to ensure that the pull rod 21 can slide in the correct position. Specifically, in one embodiment, the slide rail 111 extends radially along the top wall 11, and the slide rail 111 passes through the center of the top wall 11.

[0053] Preferably, in one embodiment, the temperature sensor 30 is a thermocouple, which enables faster and more accurate temperature measurement of the heating element 200.

[0054] Specifically, in one embodiment, the pull rod 21 is made of a rigid material with low thermal conductivity, thereby facilitating operation by the operator.

[0055] When measuring the surface temperature of the heating element 200 using the heating element temperature measuring device 100, the support assembly 10 is placed inside the heating chamber of the heating appliance, with all the contact feet 1221 tightly fitted to the bottom of the heating chamber. After determining the temperature measurement point according to the size of the heating element 200, the pull rod 21 is pulled horizontally, and the vertical position of the guide 22 is adjusted so that the temperature sensor 30 is in close contact with the position of the heating element 200 to be measured to complete the temperature measurement.

[0056] The above description is merely an embodiment of this utility model. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this utility model, but these improvements all fall within the protection scope of this utility model.
