Description

Technical Field

[0001] This invention relates to the tobacco industry, specifically to non-contact heated tobacco products and aerosol generation systems. Background Technology

[0002] With increasingly stringent global tobacco control policies and rising consumer health awareness, traditional tobacco faces pressure to reduce harm and diversify its products. Heated cigarettes, through low-temperature heating technology (typically below 350°C), release nicotine and flavor compounds from tobacco. Compared to traditional combustion cigarettes (burning at 800-900°C), this significantly reduces the formation of harmful components such as tar and carbon monoxide, aligning with the trend towards harm reduction. Heated cigarettes represent a leap from traditional combustion to low-temperature heating, meeting consumers' demands for health and convenience.

[0003] Currently, in most heated cigarettes on the market, the cigarette's smoke-generating material is in direct contact with the heating element of the device. The smoke-generating material closer to the heating element is prone to charring. The charred smoke-generating material sticks to the heating element, and after the cigarette is removed, residue remains on the heating element. When a new cigarette is inserted for the next smoke, the charred residue is reheated, producing an off-flavor and affecting the smoking experience. The common practice for cleaning the heating element is to dry-burn the heating material at a high temperature, causing the residue to carbonize and fall off. This method can only remove some of the larger residues. However, if the heating element is physically cleaned for deep cleaning, it is easily damaged. Summary of the Invention

[0004] In view of this, the technical problem to be solved by the present invention is to provide a non-contact heated tobacco product and an aerosol generation system. The smoking material in the non-contact heated tobacco product provided by the present invention can be physically isolated from the heating element. The two exchange heat through a material with strong heat transfer capacity placed in the middle, which solves the problem that the smoking material is easy to char when it is in direct contact with the heating element. At the same time, there are no decomposition residues of the smoking material on the heating element, which solves the problem that the decomposition residues of the smoking material are difficult to clean when they adhere to the heating element.

[0005] The present invention provides a non-contact heated tobacco product, which is a cup-shaped assembly 1 formed by combining a main body 100 and a heat management cover 200, wherein the cup-shaped assembly has a cavity 300 surrounded by the main body 100 and the heat management cover 200;

[0006] The main body 100 is a cup-shaped body with open ends, one end of which is provided with a mouthpiece 110;

[0007] The heat management cover 200 is a cup-shaped body that is closed at one end and open at the other end. The open end of the heat management cover 200 is connected to the end of the main body 100 away from the mouthpiece 110.

[0008] The cup-shaped assembly 1 is provided with an opening 120 for gas to enter, flow through the cavity 300 and then flow out from the mouthpiece 110.

A smoke-generating material 3 is disposed within the cavity 300 of the present invention. The smoke-generating material 3 of the present invention can be one or a combination of various forms such as strips, flakes, blocks, granules, powders, and pastes.

[0010] The main body 100 of this invention is a cup-shaped body open at both ends, with a mouthpiece 110 provided at one end. In some embodiments of this invention, the main body 100 narrows from one end to the other, with the mouthpiece 110 provided at the narrower end. A breathable baffle 130 is provided between the mouthpiece 110 and the cavity 300. The breathable baffle 130 prevents the smoke-generating material 3 from entering the mouthpiece 110, while allowing the aerosol generated by the atomization of the smoke-generating material 3 to enter the mouthpiece 110. Preferably, the breathable baffle 130 is a fibrous material and / or a baffle with openings (140); the fibrous material is preferably one or more of cotton, cellulose acetate, and polypropylene fiber.

[0011] To facilitate the insertion of the smoke-generating material 3 into the enclosed cavity 300, the mouthpiece 110 of the present invention is preferably detachably disposed at one end of the main body 100. More preferably, the mouthpiece 110 is preferably detachably disposed at one end of the main body 100, and the breathable baffle 130 is disposed within the mouthpiece 110.

[0012] The thermal management cover 200 of this invention is a cup-shaped body that is closed at one end and open at the other. Its cross-sectional shape is preferably a rounded rectangle, ellipse, circle, or rectangle. The material of the thermal management cover 200 is a material with strong radiative heat penetration or a metal material with high thermal conductivity, preferably stainless steel, copper, aluminum, quartz glass, or borosilicate glass.

Preferably, the wall thickness of the thermal management cover 200 of this invention is 0.1 mm to 3 mm.

[0013] The open end of the thermal management cover 200 of the present invention is combined with the end of the main body 100 away from the mouthpiece 110, so that the main body 100 and the thermal management cover 200 are combined to form the cup-shaped assembly 1. Specifically, the periphery of the end of the main body 100 away from the mouthpiece 110 of the present invention is provided with an inner edge 150, and the open end of the thermal management cover 200 and the end of the main body 100 away from the mouthpiece 110 are combined on the side of the inner edge 150. More specifically, the periphery of the end of the main body 100 away from the mouthpiece 110 of the present invention is provided with an inner edge 150, and the side of the inner edge 150 is provided with a groove, and the open end of the thermal management cover 200 and the end of the main body 100 away from the mouthpiece 110 are combined through the groove of the inner edge 150.

[0014] To improve ease of production and sealing when assembling the main body 100 with the thermal management cover 200, the inner edge 150 of the present invention is preferably detachably disposed on the periphery of the end of the main body 100 away from the mouthpiece 110. The inner edge 150 of the present invention can be made of a rigid material or a soft material.

[0015] The cup-shaped assembly 1 of the present invention is provided with an opening 120 for gas to enter, flow through the cavity 300, and exit from the mouthpiece 110. Specifically, at least one of the inner edge 150 and the main body 100 of the cup-shaped assembly 1 of the present invention is provided with an opening 120, so that external airflow can enter the closed cavity 300 through the opening 120. When the opening 120 is provided on the main body 100, the position of the opening 120 is preferably close to the inner edge 150, so that the airflow entering from the opening 120 can also carry out the aerosol generated by the smoke-generating material near the bottom cover. In one embodiment of the present invention, the opening 120 is provided on the inner edge 150 of the main body 100 of the cup-shaped assembly 1.

[0020] The housing 210 of the present invention is provided with an air hole 250 communicating with the receiving cavity. Specifically, the air hole 250 is communicating with the cavity 300 of the non-contact heated tobacco product. The airflow during inhalation can enter the receiving cavity of the power supply device 2 through the air hole 250, and then enter the cavity 300 of the tobacco product through the opening 120. Through the smoke-generating material 3, the aerosol generated by the atomization of the smoke-generating material 3 is finally discharged from the mouthpiece 110.

[0021] This invention provides a non-contact heated tobacco product and an aerosol generation system. The non-contact heated tobacco product provided by this invention can be combined with this power supply device to form an aerosol generation system. The non-contact heated tobacco product and the power supply device are configured for very convenient combination and disassembly.
