[0024] For a clearer understanding of the technical features, objectives, and effects of the present invention, the specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0025] As Figures 1 to 3 shown, the shunt atomization module 1 in an embodiment of the present invention is used for an electronic atomization device to atomize a flavor aerosol-forming matrix, such as a flavor pod or other solid aerosol-forming matrix. The electronic atomization device is also used to atomize a liquid aerosol-forming matrix. The aerosol formed after the electronic atomization device atomizes the liquid aerosol-forming matrix flows into the shunt atomization module to atomize the flavor aerosol-producing matrix.

[0026] The shunt atomization module 1 includes a receiving cavity 11 and a heating component 12, a heat insulation component 13, a shunt air passage 14 disposed outside the receiving cavity 11, and an air inlet A for intake air and an air outlet B for outlet air respectively. The air outlet B is usually connected to the smoke outlet. After the shunt atomization module 1 is installed in the electronic atomization device, the receiving cavity 11 is used to accommodate the aerosol-forming matrix 2, and the heating component 12 is used to heat the aerosol-forming matrix 2 accommodated in the receiving cavity 11 to atomize the active substances in the aerosol-forming matrix 2. The active substances can be nicotine or pharmacological components, etc. The heat insulation component 13 is disposed outside the heating component 12 and is used to isolate the heat generated by the heating component 12 to maintain the heating efficiency and prevent the temperature of the outer shell of the electronic atomization device from being too high, thereby affecting the user experience. Further, the heat insulation component 13 isolating the heat can also avoid affecting the temperature of the aerosol in the shunt air passage 14, thereby further improving the taste of the aerosol inhaled by the user.

[0027] The air inlet A is respectively communicated with the receiving cavity 11 and the intake end of the shunt air passage 14, and the air outlet B is respectively communicated with the receiving cavity 11 and the outlet end of the shunt air passage 14. When the shunt atomization module 1 is installed in the electronic atomization device and the electronic atomization device is in the working state, the aerosol formed by the electronic atomization device atomizing the liquid aerosol-forming matrix enters from the air inlet A and flows out after passing through the receiving cavity 11 and the shunt air passage 14 respectively. The aerosol flowing through the receiving cavity 11 causes the release of the effective flavor substances of the aerosol-forming matrix 2 such as plant leaves in the receiving cavity 11, so that the aerosol flowing out of the receiving cavity 11 carries a flavor. The aerosol with the flavor is mixed with the aerosol formed by atomizing the liquid aerosol-forming matrix flowing out of the shunt air passage 14, which can obtain a better taste and improve the user experience.

[0028] In some embodiments, the air inlet A and the air outlet B are respectively located at both ends of the shunt atomization module 1. Among them, the air inlet A and the air outlet B can be respectively located at the exact centers of both ends of the shunt atomization module 1, as Figures 1 - 3As shown, that is, from the perspective of the projection effect, the air inlet A and the air outlet B are respectively located in the centers of two cross-sections. In some embodiments, the air inlet A and the air outlet B may also be respectively located on the sides at both ends of the shunt atomization module 1 (not shown in the figure), or the air inlet A and the air outlet B may also be respectively located on the side walls of the accommodation cavity 11 of the shunt atomization module 1 (not shown in the figure). In some embodiments, the air inlet A and the air outlet B are arranged staggeredly in the circumferential direction to allow more heat exchange of the aerosol flowing in from the air inlet A and flowing out from the air outlet B, so as to achieve a more layered taste. In actual use, it can be selected according to the specific structure and design of the electronic atomization device, as long as it can achieve that the aerosol entering from the air inlet A flows out through the accommodation cavity 11 and the shunt air duct 14 respectively, and the present invention does not limit this.

[0029] In some embodiments, the heating component 12 surrounds the outer circle of the side wall of the accommodation cavity 11. The heating component 12 can adopt methods such as resistance heating, infrared heating or electromagnetic heating. Resistance heating can be that the FPC wraps the accommodation cavity, or a heating thick film can be printed outside the accommodation cavity 11. In addition, the heating component 12 can also be arranged in sections along the axial direction of the accommodation cavity 11 to achieve sectional heating, etc., and the present invention does not limit this. The accommodation cavity 11 can be made of a metal with high thermal conductivity, such as stainless steel, etc. Further, the heat insulation component 13 surrounds the outer circle of the heating component 12 to improve the uniformity of heating.

[0030] In some embodiments, the shunt air duct 14 is located outside the heat insulation component 13 to prevent the temperature of the gas in the shunt air duct 14 and the gas in the accommodation cavity 11 from interfering with each other, affecting the temperature of the aerosol in the shunt air duct 14. In other embodiments, the shunt air duct 14 can also be arranged between the heat insulation component 13 and the heating component 12. In this way, the heat insulation component 13 can isolate the heat generated by the heating component 12, thereby preventing the temperature of the outer shell of the electronic atomization device from being too high and affecting the user experience.

[0031] In some embodiments, an isolation tube 15 is further sleeved outside the heat insulation component 13, and a housing 16 is sleeved outside the isolation tube 15. A shunt air duct 14 is formed between the housing 16 and the isolation tube 15, which can not only make the gas in the shunt air duct 14 not affected by other devices, but also isolate the heat conducted to the outer shell, preventing the outer shell temperature from being too high and thus affecting the user experience.

[0032] In some embodiments, air inlet holes 141 and air outlet holes 142 are respectively provided at both ends of the shunt air duct 14 to communicate with the air inlet A and the air outlet B respectively, so as to make the gas flow smoothly.

[0033] In some embodiments, small holes are provided on the side wall of the container forming the accommodation cavity 11. The shunt atomization module 1 is further provided with a flow cavity C communicating the shunt air passage 14 and the air outlet B. The aerosol entering the accommodation cavity 11 and the aerosol formed after atomizing the aerosol forming matrix 2 can enter the flow cavity C through the small holes. The aerosol from all paths is mixed in the flow cavity C, which can make the taste of the aerosol inhaled by the user better.

[0034] In some embodiments, during use, the shunt atomization module 1 is installed on the atomizer such that the air inlet is communicated with the outlet on the atomizer, and the aerosol forming matrix 2 is inserted into the accommodation cavity 11. The aerosol discharged by heating of the atomizer flows into the shunt atomization module 1 through the air inlet A. A part enters the shunt air passage 14, and a part enters the aerosol forming matrix 2 to heat the plant leaf-like substances such as the aerosol forming matrix 2 in the accommodation cavity 11 to form a mixed aerosol having the active substances in the aerosol forming matrix 2.

[0035] Meanwhile, after the heating component 12 is powered on, it can generate heat to heat the aerosol forming matrix 2. Different heating temperatures can be selected to control the release amount of active substances such as nicotine in the aerosol forming matrix 2, so that the release amount of the active substances can be more consistent before and after the entire atomization stage.

[0036] It can be understood that in the embodiments where small holes are provided on the side wall of the container of the accommodation cavity 11, the aerosol in the accommodation cavity 11 enters the flow cavity C through the small holes and is mixed with the aerosol flowing through the shunt air passage, so as to realize an aerosol with high consistency and better taste.

[0037] It can be understood that the shunt atomization module 1 can be used in cooperation with the aerosol forming matrix 2 with a specific design to achieve the effect of shunt mixing. As Figure 4 shown, it is a schematic diagram of the shunt atomization module 1 of the embodiment of the present invention assembled into an electronic atomization device and accommodating the aerosol forming matrix 2. Among them, a flow hole 21 for the gas in the shunt air passage 14 to flow out is provided on the side wall of the aerosol forming matrix 2. The gas flowing out of the shunt air passage 14 and the gas passing through the accommodation cavity 11 are mixed in the aerosol forming matrix 2 to form a mixed aerosol. Because the temperatures, concentrations, etc. of the two paths of aerosol mixed in the aerosol forming matrix 2 are different, a negative pressure is formed in the aerosol forming matrix 2, which can better carry active substances such as nicotine. In addition, the secondary mixing can coordinate the taste and make the taste smoother.

[0038] Further, the flow holes 21 are distributed along the circumferential direction of the aerosol forming matrix 2, so that the gas flowing out of the shunt air passage 14 enters the cigarette rod from the circumference, making the mixing more uniform.

[0039] Furthermore, the shunt atomization module 1 may further include a temperature control component 18 for controlling the temperature of the heating component 12, which can adjust the target temperature of heating according to user needs. The temperature control component 18 may only have a signal receiver to receive a preset signal from the battery end for control, or after obtaining power from the battery, receive the set temperature input by the user through a button or a screen.

[0040] It can be understood that an adjustment component may be additionally provided at the air inlet end of the shunt atomization module 1. The adjustment component is used to adjust the amount of aerosol flowing through the shunt air passage 14 and the accommodation cavity 11, and the amount of aerosol of plant leaf-like substances such as the aerosol formation matrix 2, so as to adjust the taste of the aerosol and better meet the user's needs.

[0041] In the embodiment of the shunt atomization module provided by the present invention, part of the aerosol after atomization by the electronic atomization device enters the accommodation cavity through the air inlet at the bottom of the accommodation cavity, so as to atomize the aerosol formation matrix and other plant leaf-like substances in the accommodation cavity, and part of it flows out towards the air outlet through the shunt air passage. The two parts of the aerosol are mixed and then inhaled by the user. The mixed aerosol has high consistency and good taste before and after, improving the user experience.

[0042] It can be understood that the above technical features can be combined arbitrarily without limitation.

[0043] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
