Embodiment 1

[0033] like figure 1 As shown, a composite heating element 1 with temperature rise and control includes: a casing 2 , welding points 3 , a heating element 4 , and a base 5 . No temperature measuring element other than the heating element 4 is arranged on the heating element 1 .

[0034] The heating element 1 is in the shape of a rod with a pointed end. The shell 2 is formed by pressing two metal sheets, the boundaries of the two sheets are pressed and sealed, and there is a cavity in the middle where the heating element 4 is placed. The heating element 4 is welded together at the welding point 3 by two different alloy materials, nickel-chromium alloy and nickel-silicon alloy. The heating element 4 is a helically wound wire-like structure with two heating circuit pins 6 exposing the casing 2 and the base 5 at the end. The base 5 is arranged on the bottom of the heating element.

Embodiment 2

[0036] A method for measuring the temperature of a composite heating element integrated with temperature rise and control. The heating element 1 described in Embodiment 1 is electrically connected to the positive and negative poles of the circuit control device through the two heating circuit pins 6 on it. The temperature control method comprises the following steps:

[0037] like figure 2 As shown, under temperature control (voltage is the state of = battery voltage), the electronic switch is regulated by PWM and then the supplied voltage is adjusted to the heating element 4, and its temperature is controlled; under temperature detection (voltage is 0 state ), the heating element 4 at t 0 Test the temperature of the heating element within a certain period of time.

Abstract

The invention belongs to the technical field of novel smoking set heating elements, and particularly relates to a composite temperature rising and controlling integrated heating element and a temperature control method. A heating element (1) comprises a heating body (4) which is welded into a whole at a welding point (3) through two different conductive materials, and a temperature measuring element except the heating body (4) is not arranged on the heating element (1). The temperature rising and controlling integrated heating element is designed for the first time, the heating body is formedby welding two kinds of conductive materials, and when high voltage is applied, the two kinds of conductive materials serve as the heating body for heating; when voltage supply is stopped, the two conductive materials are used as thermocouple temperature measurement sensors to measure the temperature of the heating element. Compared with an existing heating element, a temperature measuring sensoris omitted, the manufacturing process of the heating element is simplified, the performance of the heating element is improved, the cigarette baking effect is improved, the production cost is reduced,and better use experience is brought to consumers.

Description

technical field [0001] The invention belongs to the technical field of novel heating elements for smoking sets, and in particular relates to a composite heating element with temperature rise and control and a temperature control method. Background technique [0002] The heating element of the existing heat-not-burn cigarette smoking set is mainly to lay heating wires and thermocouples on the substrate to realize heating 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. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention has been proposed. [0004] The first aspect of the present invention provides a composite heating element with t...
