Problems solved by technology

However, the current resistance heating appliances have technical defects such as long heating preheating time, low heating efficiency, poor heating effect stability, and difficult to clean and easily damaged heating elements.
Electromagnetic heating generates an alternating magnetic field through direct current to heat the heated body, which also belongs to the category of resistance heating. It also has the disadvantages of low heating efficiency, uneven heating effect, and difficult cleaning of the heat receptor.

Embodiment 1

[0060] Embodiment 1: microwave heating non-burning smoking set of the present invention

[0061] The implementation mode of this embodiment is as follows:

[0062] The microwave heating and non-burning smoking appliance is composed of a power supply 1, a solid-state microwave source 3, a control system 4, a heating chamber 5 and an inner conductor 4 located in the heating chamber; the inner conductor is made of pure iron material and has a shape of It is umbrella-shaped, and two inner conductors are independently fixed around the heating cavity in parallel. The impedance is 40Ω, and the length is smaller than the length of the heating cavity. The microwave frequency of the solid-state microwave source is 2.45GHz.

[0063] The inner conductor of this embodiment is placed in the heating chamber of a microwave heating smoking appliance to obtain a magnetic microwave heating non-burning smoking appliance.

Embodiment 2

[0064] Embodiment 2: The conductor in the heating chamber of the microwave heating non-burning smoking appliance of the present invention

[0065] The implementation manner of this embodiment is the same as that of Embodiment 1, except that the inner conductor is made of pure copper material and is needle-shaped. It is independently fixed in the center of the heating chamber and is a coaxial line. The impedance is 35Ω, the length is less than the length of the heating cavity, and the microwave frequency of the solid-state microwave source is 2.45GHz.

[0066] The inner conductor of this embodiment is placed in the heating chamber of a microwave heating smoking appliance to obtain a magnetic microwave heating non-burning smoking appliance.

Embodiment 3

[0067] Embodiment 3: The conductor in the heating chamber of the microwave heating non-burning smoking appliance of the present invention

[0068] The implementation of this example is the same as that of Example 1, except that the inner conductor is made of copper-aluminum alloy material, and its shape is twist-shaped. It is embedded in the ceramic and then independently fixed in the center of the heating chamber. The coaxial line has an impedance of 38Ω and a length shorter than the length of the heating cavity, and the microwave frequency of the solid-state microwave source is 2.45GHz.

[0069] The inner conductor of this embodiment is placed in the heating chamber of a microwave heating smoking appliance to obtain a magnetic microwave heating non-burning smoking appliance.

Abstract

The invention relates to a microwave-heat-not-burn smoking set, which is composed of a power supply (1), a solid microwave source (3), a control system (4), a heating cavity (5) and an inner conductor (4) located in the heating cavity. The inner conductor is simple in structure, the loss of microwaves in the transmitting process is effectively reduced, and energy consumption of a system is lowered; because of the inner conductor, heat energy generated by the microwaves is only generated in a smoke formation substrate, heat is brought away by the smoke formation substrate and does not remain in the microwave-heat-not-burn smoking set, and thus the problem of overheating of a shell of the microwave-heat-not-burn smoking set is avoided; and the microwaves in the microwave-heat-not-burn smoking set are transmitted to the smoke formation substrate by the inner conductor and output from inside to outside gradually so as to penetrate through the substrate, the uniformity degree of heating of the smoke formation substrate is increased, and the microwaves are prevented from leaking and then causing harm to human bodies through structural design.

Description

【Technical field】 [0001] The invention belongs to the technical field of heating without burning. More specifically, the present invention relates to a microwave heat-not-burn smoking appliance. 【Background technique】 [0002] Heat-not-burn cigarettes are different from traditional tobacco products in the way of smoking. Compared with traditional cigarettes, heat-not-burn cigarettes use an external heat source to heat the tobacco material, and heat the tobacco material at a relatively low temperature (250-400°C) to release smoke. Heat-not-burn tobacco not only retains the smoking experience similar to traditional cigarettes, but also significantly improves the control of harmful components in smoke, sidestream smoke release, and soot pollution compared with traditional cigarettes. Therefore, heat-not-burn tobacco products are subject to The pursuit of domestic and foreign consumers has also become an important direction of technological innovation for tobacco companies. ...
