Description

FIELD

[0001] The invention relates to the technical field of aerosol generation, in particular to a heat-not-burn aerosol-generating product.

BACKGROUND

[0002] Heat-not-burn aerosol-generating products generate aerosols by heating aerosol-generating materials instead of burning. When the aerosol-generating materials are sucked by using electronic heating equipment, consumers can not only feel the fragrance of the aerosol-generating materials, but also the heat-not-burn aerosol-generating products are heated at low temperature, which can greatly reduce the undesirable substances produced by traditional cigarettes when they are burned at high temperature.

[0003] At present, in the process of smoking, air enters from the end of the heat-not-burn aerosol-generating product, passes through the heated material, takes out the aerosol generated by distillation and cracking of the heated material, and then enters the mouth of the smoker through the transmission structure. In the process of airflow, air passes through the substrate in the heating zone, exchanging heat in the form of thermal convection and carrying out aerosol. However, when the external cold air is mixed into the substrate heating zone, it will inevitably cause the temperature of the heated substrate to drop, which will lead to large fluctuations in the temperature of the substrate heating zone, different types and degrees of cracking reactions generated by materials at different temperatures, and different aroma substances released, resulting in poor suction consistency.

In addition, the heat-not-burn aerosol-generating product also includes a wrapping layer 4, which is at least arranged outside the airflow channel section 2. The wrapping layer 4 shown in Figures 1 to 2 is in its unfolded state. In this embodiment, the filter section 1, the airflow channel section 2, and the aerosol-generating material section 3 are all contained in the wrapping layer 4. It should be noted that the wrapping layer 4 only needs to at least wrap the airflow channel section 2. In other embodiments, the filter section 1, the airflow channel section 2, and the aerosol-generating material section 3 can be wrapped by different packaging materials and then assembled into a whole, which can be selected according to the actual situation, and the present invention does not limit this.

[0025] The airflow channel section 2 is provided with at least one central air channel 21 in the center, and further, at least one central air channel 21 penetrates through the center of the airflow channel section 2 in an axial direction. Specifically, the center of the airflow channel section 2 is provided with at least one central hole, and at least one central hole axially penetrates through the airflow channel section 2 to form a central air channel 21. There is gap 23 between the airflow channel section 2 and the wrapping layer 4, the gap 23 forms a lateral airflow channel; the gap 23 communicates with the central air channel 21, specifically, the gap 23 communicates with the central air channel 21 at the intersection of the aerosol-generating material section 3 and the airflow channel section 2; the wrapping layer 4 is provided with air inlet 22 at the position corresponding to the airflow channel section 2, and further, the air inlet 22 includes air inlet hole 221 or air inlet groove 222, the air inlet hole 221 or the air inlet groove 222 is arranged at any position of the part of the wrapping layer 4 wrapping the airflow channel section 2 to form an air inlet channel and communicate with the outside air. The air inlet channel communicates with the lateral airflow channel, and the external air enters the central air channel 21 through the air inlet channel. During suction, external air is sucked into the air inlet channel from the air inlet hole 221 or the air inlet groove 222, and the air enters the airflow channel section 2 downward along the lateral airflow channel, and then with lateral airflow channel enters the central air channel 21 at the intersection of the bottom of the airflow channel section 2 and the aerosol-generating material section 3, where negative pressure is formed to extract the aerosol generated by the aerosol-generating material section 3, and then passes through the central air channel 21 of the airflow channel section 2 and then enters the mouth of the smoker through the filter section 1.

[0026] Further, the cross-sectional shape of the central air channel 21 can be set to any one of circular, rectangular, zigzag, pentagonal, elliptical, honeycomb, and other shapes to extract aerosol.

[0027] Concerning Figure 3, in this embodiment, the cross-sectional shape of the central air channel 21 is set in a zigzag shape. Further, at least one groove is provided on the airflow channel section 2, and a gap 23 is formed between at least one groove and the inner wall of the wrapping layer 4, and at least one gap 23 form a lateral airflow channel. In this embodiment, at least one of the grooves is axially arranged on the outer wall of the airflow channel section 2, and the groove extends from one end of the airflow channel section 2 close to the filter section 1 to one end close to the aerosol-generating material section 3. Specifically, the groove can extend vertically or spirally from one end of the airflow channel section 2 close to the filter section 1 to one end close to the aerosol-generating material section 3, and the length of the groove is approximately equal to the height of the airflow channel section 2, that is, the outer wall of the airflow channel section 2 is completely provided with the groove in the vertical direction.

[0028] As shown in Figures 4 to 6, in some embodiments, the airflow channel section 2 may comprise a first airflow channel section 201 and a second airflow channel section 202, wherein the first airflow channel section 201 is connected with the filter section 1 and the second airflow channel section 202 is connected with the aerosol-generating material section 3; the outer wall of the first airflow channel section 201 is attached to the inner wall of the wrapping layer 4, and the gap 23 is provided between the second airflow channel section 202 and the wrapping layer 4.

The outer wall of the sealing fastener 5 is attached to the inner wall of the wrapping layer 4, and the cross-sectional area of the sealing fastener is larger than the cross-sectional area of the airflow channel section 2, so that all air entering the airflow channel section 2 from the air inlet hole or the air inlet groove flows down along the lateral air channel, enters the central air channel 21 at the intersection of the bottom of the airflow channel section 2 and the aerosol-generating material section 3, where negative pressure is formed to extract the aerosol generated by the aerosol-generating material section 3, then passes through the central air channel 21 of the airflow channel section 2 and enters the mouth of the smoker through the filter section 1.

[0031] Further, a filter material can be optionally added into the central air channel 21 of the airflow channel section 2 to form a filter to filter the aerosol; the material of the filter can be acetate fiber, polylactic acid fiber, plant polysaccharide or plant porous material. The aerosol generated by the aerosol-generating material section 3 can be primarily filtered by the filter material arranged in the central air channel 21, and then the aerosol after preliminarily filtered is secondarily filtered by the filter section 1, and finally enters the mouth of the smoker.

[0032] Further, wrapping layer 4 includes a side wall and a bottom wall. The side wall wraps the sides of the filter section 1, the airflow channel section 2 and the aerosol-generating material section 3, and the bottom wall of the wrapping layer 4 wraps the end of the aerosol-generating material section 3 away from the airflow channel section 2. Specifically, the bottom wall of the wrapping layer 4 can be set as a sealed structure, so that the bottom of the heat-not-burn aerosol-generating product is sealed and unventilated, and only the side of the heat-not-burn aerosol-generating product is ventilated, and the aerosol-generating material is heated in an oxygen-free environment, which is purer. In another embodiment, the bottom wall of the wrapping layer 4 is provided with an air inlet hole, the air inlet hole is in airflow communication with the central air channel 21, so that the bottom and the side of the heat-not-burn aerosol-generating product can be air-fed at the same time, which is helpful to increase the atomization amount and reduce the suction resistance and the inlet temperature during smoking.
