Embodiment 1 of the aerosol generating product of the present application

Embodiment 1 of the present application provides an aerosol generating product, referring to FIG. 1 to FIG. 5 , the aerosol generating product includes a housing 110 and an aerosol generating component 120 . The housing 110 is provided with an air passage 131 inside, and the side wall of the housing 110 is provided with an air inlet 111 , and the air passage 131 communicates with the outside atmosphere through the air inlet 111 . The aerosol generating assembly 120 is disposed inside the housing 110, and the airflow channel 131 is located downstream of the aerosol generating assembly 120. The airflow channel 131 is used to form a vortex airflow under the action of suction to bring out the air in the aerosol generating assembly 120. Sol, the end of the aerosol generating component 120 away from the aerosol channel 1311 is sealed.

It can be understood that the working principle of the aerosol generating product is as follows:

After the aerosol generating component 120 is heated in the housing 110 to generate aerosol, the aerosol accumulates in the aerosol generating component 120, and the end of the aerosol generating component 120 away from the aerosol channel 1311 is sealed so that the aerosol generating component 120 Separated from the outside world, outside air will not pass through the aerosol generating component 120 . When a user inhales an aerosol, the user applies a suction force to the airflow channel 131 at the end of the airflow channel 131 away from the aerosol generating component 120. At this time, the outside air does not pass through the aerosol generating component 120, but directly passes through the opening on the side wall of the housing 110. The air inlet 111 enters into the airflow channel 131 . The airflow channel 131 is located downstream of the aerosol generating assembly 120, so that outside air enters the airflow channel 131 to form a vortex airflow downstream of the aerosol generating assembly 120, and the vortex airflow makes the air pressure of the airflow channel 131 lower than the air pressure of the aerosol generating assembly 120 , a pressure difference is formed between the airflow channel 131 and the aerosol generating component 120, and the vortex airflow sucks the aerosol in the aerosol generating component 120, and takes the aerosol out of the aerosol generating product.

It should be noted that the airflow channel 131 is located downstream of the aerosol generating component 120 , which means that the aerosol flows from the aerosol generating component 120 to the airflow channel 131 .

Compared with the prior art, the aerosol generating product has at least the following technical effects:

In the embodiment of the present application, an airflow channel 131 is arranged downstream of the aerosol generating component 120, and the airflow channel 131 communicates with the outside through the air inlet 111 on the side wall of the housing 110, and the end of the aerosol generating component 120 away from the airflow channel 131 is sealed. , so that the outside air does not pass through the aerosol generating assembly 120, but directly enters the airflow channel 131 from the air inlet 111 to form a vortex airflow, so as to suck out the aerosol formed in the aerosol generating assembly 120, so that the external air does not When passing through the aerosol generating assembly 120, the aerosol is taken out, avoiding the impact of the outside air on the heating temperature of the aerosol generating assembly 120, so that the heating temperature of the aerosol generating assembly 120 can be higher (can be higher than 350°C), the atomization effect is better, and the aerosol generating component 120 can also have a better temperature storage effect, and can further enhance the flavor of the aerosol. After the aerosol is sucked into the airflow channel 131, it flows along the airflow channel 131 together with the vortex airflow, which can also realize efficient heat dissipation of the aerosol, so that the aerosol can be cooled and discharged, thereby improving user experience.

In this embodiment, the airflow channel 131 is in a spiral shape. Specifically, the airflow channel 131 is in a spiral spiral shape in a section perpendicular to the axial direction (as shown in FIG. 3 ). After the gas enters the gas flow channel 131, there are two flow directions, one is to flow around the axial direction, and the other is to flow along the axial direction. When the outside air is sucked into the airflow channel 131 from the air inlet 111, it will flow spirally around the axial direction under the guidance of the airflow channel 131, and gradually approach the area of the vortex axis 1312. When the airflow enters the vortex When it is near the center of rotation 1312 , it will flow axially under the action of external suction to be discharged out of the casing 110 . When the gas forms a helical vortex airflow under the guidance of the airflow channel 131, the vortex airflow will generate a suction force on the aerosol in the aerosol generating component 120 downstream thereof, sucking the aerosol into the airflow channel 131, and Other gases are discharged out of the housing 110 together, so that the aerosol generating component 120 can discharge the aerosol without new outside air flowing through. After the aerosol enters the airflow channel 131, it can also flow in a spiral around the axial direction for a certain distance and then flow outward along the axial direction. During the process of the aerosol flowing around the axial direction, it can cool down the aerosol. Realize the heat dissipation of aerosol.

In this embodiment, the area of the vortex axis of the air flow channel 131 is an aerosol channel 1311 , and the aerosol channel 1311 is connected to the gas outlet of the aerosol generating component 120 . It can be understood that the aerosol channel 1311 is a part of the air flow channel 131 for the aerosol in the aerosol generating component 120 to pass through. The airflow velocity in the area of the vortex axis 1312 of the airflow channel 131 is relatively fast, and the suction force is large. The area of the vortex axis 1312 of the airflow channel 131 is partially connected to the outlet end of the aerosol generating component 120, and the aerosol can be sucked out more easily. Into the aerosol channel 1311, the aerosol is discharged outside through the aerosol channel 1311.

It can be understood that at least the area of the vortex axis 1312 of the airflow channel 131 is aligned with the gas outlet of the aerosol generating component 120 . In this embodiment, the air outlet end of the aerosol generating component 120 can also cover the part outside the area of the vortex axis 1312, and expand the outlet of the aerosol to be discharged to the airflow channel 131. After the aerosol enters the airflow channel 131, it can also go around The vortex axis 1312 flows for a certain distance before being discharged. When the aerosol flows around the vortex axis 1312, the cooling effect of the aerosol can be achieved.

In this embodiment, the airflow channel 131 is formed by surrounding the air guide 130 , the air guide 130 is disposed inside the casing 110 , and the cross section of the air guide 130 is spiral. Specifically, the cross section of the deflector 130 is arranged spirally in the shape of an Archimedes line. It can be understood that the deflector 130 may be installed inside the housing 110 through assembly, or may be integrally formed with the inside of the housing 110 .

In one embodiment, the cross-section of the air guide 130 is spiral, and the interval between adjacent layers of the spiral cross-section gradually decreases from the outside to the inside, that is, the closer to the center of the spiral, the interval between adjacent layers The smaller the airflow channel 131 is, the smaller it is from the outside to the inside, so that the external air is gradually compressed when it spirally flows around the axis along the airflow channel 131, and the compressed air can increase the absorption effect on aerosol.

In some embodiments, the deflector 130 can be selected from a sheet composed of metal foil, polymer sheet, and non-porous paper or cardboard, and can also be selected from polyethylene, polypropylene, polyvinyl chloride, polyterephthalmic A sheet composed of any one of ethylene glycol formate, polylactic acid, cellulose acetate and aluminum foil, after the aerosol enters the airflow channel 131, the flow guide can absorb the heat of the aerosol, thereby realizing the cooling output of the aerosol . In some implementations, the flow guide 130 can also be made of phase change materials.

In this embodiment, the air inlet 111 is disposed on the side wall of the casing 110 and is disposed correspondingly to the flow guide 130 . Specifically, the air inlet 111 and the deflector 130 are located at the same level, which reduces the distance of air entering the airflow channel 131 from the air inlet 111 and improves the efficiency of forming the vortex airflow.

In this embodiment, there are multiple air inlets 111 , and the multiple air inlets 111 may be arranged to be distributed around the outer side of the housing 110 , and/or arranged to be distributed along the axial direction of the housing 110 . Multiple air intake holes can improve the efficiency of air entering the airflow channel 131 . It should be noted that the multiple mentioned in this application specifically means that the number is greater than one.

In some implementations, when the multiple air inlets 111 are arranged to be distributed along the axial direction of the housing 110, the multiple air inlets 111 can be arranged to face the air inlet end 1313 of the airflow channel 131, that is, the multiple air inlets The opening 111 is disposed facing the outermost opening of the air guide 130 , so as to shorten the path of outside air entering the airflow channel 131 .

In some implementations, when the multiple air inlets 111 are arranged to be distributed along the axial direction of the housing 110, the multiple air inlets 111 can be arranged such that the distance between adjacent air inlets 111 is from bottom to top in the axial direction. Gradually increase to form a dense arrangement at the bottom and sparse at the top, so that the air intake of the lower part of the air inlet 111 is larger, and the air intake of the upper part of the air inlet 111 is less, thereby balancing the concentration and temperature of the aerosol to avoid Excessive air intake will cause the aerosol to be diluted, which will affect the taste of the user.

In other embodiments, the number of the air inlet 111 can also be set to one. When the number of the air inlet 111 is set to one, the efficiency of air entering the airflow channel 131 can be improved by increasing the area of the air inlet 111 .

The aerosol in the inner cavity is sucked out, thereby realizing the natural uptake of the aerosol. The tubular heating element 121 can centrally store the overflowing aerosol in the gap between the user inhaling the aerosol, and when the aerosol is sucked out, the aerosol can be more concentrated and the inhalation taste is better. Moreover, adopting this method of naturally ingesting aerosols can ensure that the inhaled aerosols are generated after the aerosol generating substrate 122 is fully heated, effectively reducing the output of harmful substances and ensuring the health of consumers. It can be understood that, in this embodiment, the top opening of the heating element 121 is the gas outlet of the aerosol generating component 120 .

Further, in order to enhance the guiding effect of the heating element 121 on the aerosol, the heating element 121 can be set as an inverted trumpet-shaped tube with a narrow top and a wide bottom, or an inverted tapered guide tube can be formed on the top of the heating element 121, so that the aerosol After the inner cavity of the heating element 121 is collected, it enters into the airflow channel 131 .

The above-mentioned shape of the air hole 1211 specifically refers to the cross-sectional shape of the air hole 1211 .

Of course, in other embodiments, the heating element 121 may also be made of a metal product with air permeability, such as metal felt. When the heating element 121 is made of metal felt, since the material porosity of the heating element 121 is relatively large, the setting of the vent hole 1211 can be omitted on the side wall of the tubular heating element 121, and the aerosol can directly overflow through the tube wall of the heating element 121 to the heating element. body 121 lumen.
