Description

Technical Field

[0001] The invention belongs to the field of novel cigarette smoking articles, and in particular relates to a matching component of an aerosol generating device which is convenient to replace and clean, and a smoking article comprising the same. Background Art

[0002] When tobacco burns, the smoke produced contains harmful substances such as tar, nicotine, carbon monoxide, aldehydes, and amines. As people pay more and more attention to health, more and more consumers are trying new products. Heat-not-burn smoking products have rapidly emerged and are showing a rapid growth trend, leading to profound changes in the product structure of the world tobacco market. Heat-not-burn smoking means smoking tobacco through a controllable heating method. While satisfying consumers' tobacco characteristics, it reduces the release of harmful components in the smoke and only heats the tobacco without burning it, so that it produces neither second-hand smoke nor ash.

[0003] When the current heat-not-burn smoking device is working, when the cigarette is heated and baked at high temperature, aerosols including smoke agents, moisture, flavors and solvents will be produced. The aerosols will continuously seep from the bottom of the smoking device to the outer surface of the smoking device, affecting the user experience. Summary of the invention

[0004] The present invention is proposed to solve at least one of the above problems.

[0005] A first aspect of the present invention provides an aerosol generating device supporting component that is easy to replace and clean, and the aerosol generating device supporting component comprises:

[0006] The aerosol storage chamber 4 is a hollow structure, and an aerosol guide member 5 is arranged / formed on the inner surface of the bottom thereof. The aerosol storage chamber 4 can be detachably connected to the external component;

[0007] The aerosol guide member 5 is a protruding portion protruding upward and arranged / formed on the inner surface of the bottom of the aerosol storage chamber 4, and the upper surface of the protruding portion is an arc-shaped convex surface.

[0008] Preferably, the aerosol storage chamber 4 also has a connection portion that is detachably connected to an external component.

[0009] Preferably, an acute angle α formed between a tangent line of the arc-shaped convex surface and a horizontal line is between 0° and 90°.

[0010] Preferably, the aerosol guide member 5 is made of a high temperature resistant and aerosol-repellent material, such as polytetrafluoroethylene or PEEK (polyetheretherketone);

[0011] High temperature resistance means that under atmospheric pressure, at 350 degrees Celsius, no deformation occurs without external force.

[0012] Aerosol-repellent material refers to a material that is both oleophobic and hydrophobic.

[0013] Preferably, the aerosol guiding member 5 is made of polytetrafluoroethylene, has a bright surface, is resistant to high temperatures and is aerosol-repellent.

[0014] Preferably, the aerosol guide member 5 has a heating element insertion hole 5-1. In this case, it is suitable for a central heating type smoking device.

[0015] Preferably, the aerosol generating device supporting assembly further comprises: a hollow cigarette accommodating chamber 2;

[0016] The lower end of the cigarette accommodating chamber 2 is detachably connected to the upper end of the aerosol storage chamber 4 .

[0017] Preferably, the side wall of the cigarette accommodating chamber 2 is provided with an air inlet 3.

[0018] Preferably, the lower end of the cigarette accommodating chamber 2 and the upper end of the aerosol storage chamber 4 are detachably connected via a connecting buckle 8 .

[0019] Preferably, the aerosol storage chamber 4 is an H-shaped hollow structure, including an upper hollow structure portion, a lower hollow structure portion, and an aerosol guide member 5 located therebetween;

[0020] The upper hollow structure portion is a cigarette accommodating cavity, and an air inlet 3 is provided on its side wall.

[0021] Preferably, the heating element 7 is fixed on the heating element fixing seat 6, and the heating element fixing seat 6 is accommodated in the lower hollow structure part.

[0022] The second aspect of the present invention provides an electrically heated smoking device comprising the aerosol generating device supporting components described in the first aspect.

[0023] The above technical solutions can be freely combined under the premise of no contradiction.

[0024] The present invention has the following beneficial effects:

[0025] The present invention provides an aerosol generating device supporting component that is easy to replace and clean. The aerosol storage chamber 4 can be replaced, which solves the problem that the aerosol generated after the smoking device has been working for a long time is accumulated at the bottom of the heating cup body and is difficult to clean, or easily seeps out to the outer surface of the smoking device. In particular, the present invention designs an arc-shaped aerosol guide member 5 at the bottom of the aerosol storage chamber 4, which is both resistant to high temperatures and can guide the aerosol, and can guide the aerosol to the lowest point of the arc, so that the aerosol is not easy to overflow.

[0026] The present invention also provides two specific schemes. In scheme 1, the aerosol storage chamber 4 and the cigarette holding chamber 2 are designed to be detachably connected, and can be disassembled at will to replace and clean the aerosol storage chamber 4; in scheme 2, the cigarette holding chamber 2 is omitted, and the aerosol storage chamber 4 is designed to both fix cigarettes and store aerosols, and can be disassembled to replace and clean the aerosol storage chamber 4.
