Description

Technical Field

[0001] The present invention relates to the technical field of aerosol generation, and particularly to non-combustion heating type aerosol generation products.

Background Art

[0002] Non-combustion heating type aerosol generation products generate aerosol by heating aerosol generation materials instead of by combustion. When the consumer sucks the aerosol generation material with an electronic heating device, the consumer can not only feel the smell of the aerosol generation material, but also the non-combustion heating type aerosol generation product can be heated under low temperature conditions, and the undesirable substances generated in conventional cigarettes during high temperature combustion can be significantly reduced.

[0003] In the suction process of current non-combustion heating type aerosol generation products, air enters from the end of the aerosol generation product, passes through the heated material, extracts the aerosol generated by the distillation and decomposition of the heated material, and enters the smoker's mouth through the delivery structure. During the process of air flow, the air passes through the base material in the heating area, performs heat exchange in the form of heat convection, and extracts the aerosol. However, when external cold air mixes into the heating area of the base material, it will inevitably cause a decrease in the temperature of the heated base material, resulting in a large temperature fluctuation in the heating area of the base material. Different temperature decomposition reaction types and degrees of the material are different, and the released aroma substances are also different, resulting in a problem of poor suction At the time of taste consistency.

In addition, the non-combustion heating type aerosol generating product further includes a coating layer 4, and the coating layer 4 is installed at least outside the air flow path segment 2. The coating layer 4 shown in FIGS. 1 to 2 is in the state of being unfolded. In this embodiment, the filter segment 1, the air flow path segment 2, and the aerosol generating material segment 3 are all accommodated in the coating layer 4. Note that the coating layer 4 only needs to cover at least the air flow path segment 2. In other embodiments, the filter segment 1, the air flow path segment 2, and the aerosol generating material segment 3 may be assembled together after being covered with different packaging materials respectively, and can be selected based on the actual situation, and the present invention does not limit this.

[0025] Specifically, the material of the filter segment 1 includes any one of materials such as cellulose acetate fiber, polypropylene fiber, paper filter plug, sheet tobacco, polylactic acid fiber, resin, plant polysaccharide, resin, and plant porous material, etc., filters and adsorbs the aerosol, and achieves the effect of improving the cleanliness and comfort of the aerosol.

Further, the aerosol generating material segment 3 may also be called a base material segment, and the material of the aerosol generating material segment 3 may include any one or more of solid base materials such as grooved, sheet-like, particulate, powdery, and paste-like.

[0026] At least one central gas flow path 21 is provided at the center of the air flow passage segment 2. Further, at least one central gas flow path 21 is provided axially through the center of the air flow passage segment 2. Specifically, at least one central hole is provided at the center of the air flow passage segment 2, and at least one central hole axially penetrates the air flow passage segment 2 to form the central gas flow path 21. Between the air flow passage segment 2 and the coating layer 4 At least one There is a gap 23, and the gap 23 forms a side gas flow path. The gap 23 is in air flow communication with the central gas flow path 21. Specifically, the gap 23 communicates with the central gas flow path 21 at the interface between the aerosol generating material segment 3 and the air flow passage segment 2. At the position of the coating layer 4 corresponding to the air flow passage segment 2 At least one An air inlet 22 is provided, and further, the air inlet 22 At least one Includes an air inlet hole 221 or At least one An air inlet groove 222. The air inlet hole 221 or the air inlet groove 222 is provided at any position of the coating layer 4 covering a part of the air flow passage segment 2, forms an air inlet passage, and communicates with the outside air. The air inlet passage communicates with the side gas flow path, and the outside air passes through the air inlet passage Via the side gas flow pathIt enters the central gas flow path 21. During suction, outside air is inhaled into the intake passage from the intake holes 221 or the intake grooves 222. The air enters the air flow path segment 2 downward along the side gas flow path, and enters the central gas flow path 21 at the intersection of the bottom of the air flow path segment 2 and the aerosol generating material segment 3 along the side gas flow path. A negative pressure is formed here to extract the aerosol generated in the aerosol generating material segment 3. Then, it passes through the central gas flow path 21 of the air flow path segment 2 and enters the smoker's mouth through the filter segment 1.

[0027] Furthermore, the cross-sectional shape of the central gas flow path 21 may be set to any of shapes such as circular, rectangular, serrated, star-shaped, elliptical, and honeycomb-shaped to extract the aerosol.

[0028] Referring to FIG. 3, in this embodiment, the cross-sectional shape of the central gas flow path 21 is set to be serrated. Furthermore, at least one groove is provided in the air flow path segment 2, and a At least one gap 23 is formed between at least one groove and the inner wall of the coating layer 4, and a plurality of gaps 23 form one side gas flow path. In this embodiment, at least one groove is axially provided on the outer wall of the air flow path segment 2, and the groove extends from one end close to the filter segment 1 of the air flow path segment 2 to one end close to the aerosol generating material segment 3. Specifically, the groove may extend vertically or spirally from one end close to the filter segment 1 of the air flow path segment 2 to one end close to the aerosol generating material segment 3. The length of the groove is approximately equal to the height of the air flow path segment 2, that is, the structure of the groove is provided throughout the entire vertical direction of the outer wall of the air flow path segment 2.

[0029] As shown in FIGS. 4 to 6, in some embodiments, the air flow path segment 2 may include a first air flow path segment 201 and a second air flow path segment 202. The first air flow path segment 201 is connected to the filter segment 1, the second air flow path segment 202 is connected to the aerosol generating material segment 3. The outer wall of the first air flow path segment 201 is in close contact with the inner wall of the coating layer 4, and the gap 23 is provided between the second air flow path segment 202 and the coating layer 4. In this embodiment, the first air flow path segment 201 refers to the segment located downstream of the air flow path segment 2, that is, the segment connected to the filter segment 1, and the second air flow path segment 202 refers to the segment located upstream of the air flow path segment 2, that is, the segment connected to the aerosol generating material segment 3. Therefore, in this embodiment, grooves are provided only in the second air flow path segment 202. Further, the length of at least one groove is substantially equal to the height of the second air flow path segment 202. A gap 23 is formed between the position where the groove of the second air flow path segment 202 is provided and the coating layer 4. The plurality of gaps 23 form one side gas flow path. No groove is provided in the first air flow path segment 201, and the first air flow path segment 201 is in direct contact with the coating layer 4. Therefore, the cross-sectional area of the first air flow path segment 201 is larger than the cross-sectional area of the second air flow path segment 202. The purpose is that the air 221 or the intake hole 222 entering the air flow path segment 2 from or the intake groove directly flows upward to the filter segment 1, preventing it from affecting the taste. The air 221 or the intake hole 222 entering the air flow path segment 2 from or the intake groove all flows downward along the side gas flow path, enters the central gas flow path 21 at the intersection of the bottom of the air flow path segment 2 and the aerosol generating material segment 3, forms a negative pressure here, and ensures that the aerosol generated in the aerosol generating material segment 3 is extracted. Then, it passes through the central gas flow path 21 of the air flow path segment 2 and enters the smoker's mouth through the filter segment 1.

[0030] Furthermore, as shown in FIG. 7, in some other embodiments, the structure of this embodiment is similar to the structure of the embodiment shown in FIG. 1, and the difference is that a sealing member 5 is further provided between the filter segment 1 and the air flow path segment 2 of this embodiment.

As can be understood, in some other embodiments, the shape of the central air guide hole 51 of the sealing member 5 may be a gear shape or other shapes, which are not limited herein.

[0031] As can be understood, the function of the sealing member 5 is similar to that of the first air flow path in the above embodiment Segment 201, and the air intake hole 221 or the air intake groove 222 prevents the air entering the air flow path segment 2 from directly flowing upward through the filter segment 1 and affecting the taste. The outer wall of the sealing member 5 is in close contact with the inner wall of the coating layer 4, and the cross-sectional area of the sealing member 5 is larger than the cross-sectional area of the air flow path segment 2. All the air entering the air flow path segment 2 from the air intake hole 221 or the air intake groove 222 flows downward along the side gas flow path and enters the central gas flow path 21 at the intersection of the bottom of the air flow path segment 2 and the aerosol generating material segment 3, where a negative pressure is formed to ensure the extraction of the aerosol generated in the aerosol generating material segment 3. Then, it passes through the central gas flow path 21 of the air flow path segment 2, passes through the filter segment 1, and enters the smoker's mouth.

[0032] Furthermore, a filter material is selectively added to the central gas flow path 21 of the air flow path segment 2 to form a filter member, and the aerosol can be filtered. The material of the filter member may be cellulose acetate fiber, polylactic acid fiber, plant polysaccharide or plant porous material. The aerosol generated in the aerosol generating material segment 3 first passes through the filter material provided in the central gas flow path 21 to complete the initial filtering. Then, the aerosol after the initial filtering further undergoes secondary filtering through the filter segment 1 and finally enters the smoker's mouth.

[0033] Furthermore, the coating layer 4 includes a side wall and a bottom wall. The side wall covers the sides of the filter segment 1, the air flow path segment 2, and the aerosol generating material segment 3.

Specifically, the bottom wall of the coating layer 4 may be installed as a sealed structure, whereby the non-combustion heated aerosol generating product has a sealed bottom and does not allow air to pass through, and air is only inhaled from its side. The aerosol generating material is heated in an oxygen-free environment and becomes cleaner. In another embodiment, intake holes are provided in the bottom wall of the coating layer 4, and the intake holes are in air flow communication with the central gas flow path 21, whereby air is inhaled simultaneously from the bottom and the side of the non-combustion heated aerosol generating product, contributing to increasing the atomization amount, reducing the inhalation resistance, and lowering the temperature entering the mouth during inhalation.

[0034] Furthermore, the shape of the coating layer 4 may be sheet-like or tube-like, and the material of the coating layer 4 includes any one or more of paper material, tin foil, and aluminum foil.

[0035] Specifically, the coating layer 4 is in the form of a bendable sheet, which may be formed by winding a paper material, or may be in the form of a paper leaf when unfolded, and can form a single hollow column structure that can entirely cover the filter segment 1, the air flow passage segment 2, and the aerosol generating material segment 3 when bent. In another embodiment, the coating layer 4 may be tubular, that is, it may be a pre-formed paper tube, and the tubular coating layer 4 is entirely fitted outside the filter segment 1, the air flow passage segment 2, and the aerosol generating material segment 3.
