[0022] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0023] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0024] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0025] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0026] The present application provides a temperature detection device for a smoking device. When the spring is in a compressed state, the first bending portion drives the temperature sensing element to move toward the center hole. After reaching equilibrium, the temperature sensing element is pressed against the heating plate to avoid inaccurate temperature detection caused by loosening or shaking of the temperature sensing element, thereby improving the accuracy of temperature detection.

[0027] like Figure 1 and 2 As shown, the temperature detection device of the smoking device provided in the present application includes a temperature collecting element (not shown in the figure), a plurality of temperature sensing elements 50, an upper seat 10 and a lower seat 20 arranged at intervals, and a plurality of rigid support members 30 and a plurality of springs 40 arranged at intervals between the upper seat 10 and the lower seat 20.

[0028] The upper body 10 and the lower body 20 have coaxial central holes for the heating plate in the smoking device to pass through. Figure 1 and 2 As shown, the upper seat body 10 is provided with a center hole 11, and the lower seat body 20 is also provided with a coaxial and same-diameter center hole.

[0029] As an embodiment, the upper body 10 and / or the lower body 20 are provided with threaded holes connected to the smoking utensils, so as to facilitate the stable connection between the smoking utensils and the temperature detection device. Figure 1 and 2 As shown, a threaded hole 12 is provided on the upper seat body 10 .

[0030] At least one spring sheet is provided between adjacent rigid support members. Figure 1 and 2 As shown, the temperature detection device includes two rigid support members 30 and two spring plates 40. A spring plate 40 is provided between two adjacent rigid support members 30, and a rigid support member 30 is provided between two adjacent spring plates 40. It can be understood that more than two rigid support members and more than two spring plates can be provided along the circumference of the seat body, and the relative positions and quantities of the rigid support members and the spring plates can also be provided according to actual needs.

[0031] As an embodiment, the rigid support member 30 is a metal thin plate. On the one hand, it reduces the overall weight of the temperature detection device while meeting the rigid support requirements. On the other hand, the two ends of the thin plate can be bent and then connected to the upper and lower base bodies and adhered to the bottom and top surfaces of the upper and lower base bodies, thereby improving the compactness of the entire structure.

[0032] As an embodiment, the rigid support member 30 is made of brass, which has good plasticity and is easy to process and shape.

[0033] The spring sheet 40 is a metal material formed by multiple bending sections, wherein the first bending section 41 is closer to the center hole 11 than the second bending sections 42 on both sides thereof, and the temperature sensing element 50 is positioned inside the first bending section 41, and the temperature sensing element 50 is connected to the temperature collection element through a wire. In the installed state, the spring sheet 40 is compressed, and in the compressed state of the spring sheet 40, the backlog of the second bending section 42 causes the first bending section 41 to drive the temperature sensing element 50 to move toward the center hole 11, and after reaching equilibrium, the temperature sensing element 50 is pressed against the heating sheet 60.

[0034] As an example, Figure 1 As shown, the first bending portion 41 is a first U-shaped notch opening toward the center hole 11 , and the size of the first U-shaped notch matches the temperature sensing element 50 , so that at least a portion of the temperature sensing element 50 is snapped into the first U-shaped notch to achieve positioning of the temperature sensing element 50 .

[0035] On this basis, the second bent portion 42 is a second U-shaped notch opening toward the center hole, and at least a portion of the side wall 421 of the second U-shaped notch close to the first U-shaped notch forms a certain angle with the axis of the center hole 11, that is, the two are not perpendicular. The adjacent side walls of the first bent portion 41 and the second bent portion 42 are connected by bending of the material to form a third bent portion 43, thereby increasing the elastic compression force of the first bent portion 41 through the third bent portion 43, increasing the clamping force on the temperature sensing element 50 and the elastic clamping force toward the center hole 11.

[0036] Preferably, the heights of the first bending portions 41 on different spring sheets 40 are the same or different, preferably different, so that different temperature sensing elements can detect the temperatures at different axial positions on the heating plate, making the final temperature more accurate.

[0037] As an embodiment, the spring piece 40 is made of brass, which has good plasticity and is conducive to bending and forming.

[0038] As an embodiment, the temperature sensing element 50 is a platinum resistor or a thermocouple.

[0039] In the working state, the temperature detection device is inserted into the heated cigarette holding cavity of the smoking device so that the heating plate passes through the center hole, and the temperature detection device is fixed to the smoking device by screws. At this time, the temperature sensing element is in contact with the heating plate in the smoking device. After the connection is stable, the heating function of the smoking device is turned on, and the heat of the heating plate is transferred to the temperature sensing element. The temperature sensing element outputs the corresponding resistance value to the temperature conversion module of the temperature acquisition element through a wire. After the temperature conversion module converts the resistance value into the corresponding temperature, it is transmitted to the host computer through the communication module. The host computer comprehensively processes the temperature information of all temperature sensing elements, obtains the heating temperature of the heating rod, and displays it on the display screen for the user's reference. It should be noted that the host computer uses the existing technology to process and display the temperature information, and this application does not improve the data processing and display technology.

[0040] Although some specific embodiments of the present application have been described in detail by way of example, it should be understood by those skilled in the art that the above examples are only for illustration, not for limiting the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
