Embodiment 1

[0036] Such as figure 1 As shown, an air heating element integrating temperature measurement and control includes: a receiving chamber 1 , a connecting plate 2 , a heating element 4 , and a heating chamber 5 .

[0037] The accommodating chamber 1 is used for accommodating the smoking base, and is located above the heating chamber 5 and the two are integrated into a whole through the connecting plate 2 . The connecting plate 2 is made of stainless steel.

[0038] The heating chamber 5 is a closed chamber, which communicates with the accommodating chamber 1 only through the through hole 6 on the connecting plate 2 . The heating element 4 is located in the heating chamber 5 to heat the air.

[0039] The heating element 4 is welded at the welding point 3 by two alloy materials, nickel-chromium-nickel-silicon. After the two alloy materials are welded, they will heat up and generate heat under the condition of electrification, and can be used as a thermocouple temperature sensor ...

Embodiment 2

[0042] A temperature measurement and control method for an air heating element integrated with temperature measurement and control. The heating element described in Embodiment 1 is electrically connected to the positive and negative poles of the circuit control device through the two heating circuit pins 7 on it. The temperature measurement and control method Include the following steps:

[0043] Such as image 3 shown, under temperature control (voltage V 0 = under the battery voltage state), the electronic switch is regulated by PWM, and then the voltage supplied to the heating element 4 is periodically regulated to control its temperature;

[0044] During temperature detection (in the state where the voltage is 0), the heating element 4 is at t 0 Within the time, the temperature of the heating chamber 5 is tested.

Abstract

The invention belongs to the technical field of novel smoking set heating elements, and particularly relates to a temperature measurement and control integrated air heating element and a temperature measurement and control method. The temperature measurement and control integrated air heating element comprises an accommodating cavity (1), a connecting plate (2), a heating cavity (5) and a heatingbody (4), wherein the connecting plate (2) is arranged between the accommodating cavity (1) and the heating cavity (5); the heating body (4) is arranged in the heating cavity (5), the heating body (4)is formed by welding two different conductive materials at a welding point (3) integrally, and the heating element is not provided with a temperature measuring element other than the heating body (4). By adopting the temperature measurement and control integrated air heating element, the air is heated through using the heating body, heat is transmitted to the connecting plate through hot air, andthen the heat is transmitted to a fuming substrate in the accommodating cavity for achieving the purpose of heating, thereby avoiding the situation that the heating body is damaged since the fuming substrate makes direct contact with the heating body frequently.

Description

technical field [0001] The invention belongs to the technical field of novel heating elements for smoking utensils, and in particular relates to an air heating element integrating temperature measurement and control and a temperature measurement and control method. Background technique [0002] The heating elements of existing heat-not-burn cigarette appliances mainly lay heating wires and thermocouples on the substrate to realize heat generation and temperature measurement. Due to the short distance between the thermocouple and the heating wire, the heating element is prone to short circuit, and the manufacturing process of the heating element is complicated. Moreover, the heating circuit and the temperature measuring circuit are designed separately, and the circuit is complicated. [0003] In addition, the contact area between the solid heating element and the heating product is limited, and it is easy to heat unevenly, which affects the user's suction experience. Conte...
