BACKGROUND

[0002] In the prior art, a vaporization method of a flavor cartridge or a cigarette is generally as follows: aerosol formed from e-liquid enters from the bottom of the flavor cartridge or the cigarette, and a tobacco substance in the flavor cartridge or the cigarette is heated to release nicotine for a user to inhale.

DETAILED DESCRIPTION

[0020] In order to have a clearer understanding of the technical features, the objectives, and the effects of the present invention, specific implementations of the present invention are now illustrated in detail with reference to the accompanying drawings.

[0021] As shown in FIG. 1 to FIG. 3, a diverging vaporization module 1 of an embodiment of the present invention is provided. The diverging vaporization module 1 is configured for use in an electronic vaporization device to vaporize a flavor aerosol-forming matrix, such as a flavor cartridge or other solid aerosol-forming matrix. The electronic vaporization device is further configured to vaporize a liquid aerosol-forming matrix. Aerosol formed after the electronic vaporization device vaporizes the liquid aerosol-forming matrix flows into the diverging vaporization module to vaporize the flavor aerosol-forming matrix.

[0022] The diverging vaporization module 1 includes an accommodating cavity 11; a heating component 12, a thermal insulation component 13, and a diverging airway 14 arranged outside the accommodating cavity 11; and an air inlet A and an air outlet B respectively configured for air intake and exhaust. The air outlet B is generally connected to a smoke outlet. After the diverging vaporization module 1 is installed in the electronic vaporization device, the accommodating cavity 11 is configured to accommodate an aerosol-forming matrix 2, the heating component 12 is configured to heat the aerosol-forming matrix 2 accommodated in the accommodating cavity 11, so as to vaporize an effective substance in the aerosol-forming matrix 2. The effective substance may be nicotine or other pharmacological ingredient, etc. The thermal insulation component 13 is arranged on an outer side of the heating component 12 and is configured to isolate heat generated by the heating component 12, so as to maintain the heating efficiency and prevent the temperature of a shell of the electronic vaporization device from being excessively high to affect the user experience. Further, the isolation of the heat by the thermal insulation component 13 can also avoid affecting the temperature of the aerosol in the diverging airway 14, thereby further improving the taste of the aerosol inhaled by the user.

[0023] The air inlet A is respectively in communication with the air inlet ends of the accommodating cavity 11 and the diverging airway 14. The air outlet B is respectively in communication with the air inlet ends of the accommodating cavity 11 and the diverging airway 14. When the diverging vaporization module 1 is installed in the electronic vaporization device and the electronic vaporization device is in an operating state, the aerosol formed after the electronic vaporization device vaporizes the liquid aerosol-forming matrix enters from the air inlet A and flows out respectively through the accommodating cavity 11 and the diverging airway 14. The aerosol flowing through the accommodating cavity 11 causes the release of an effective flavor substance from a plant-grass like substance such as the aerosol-forming matrix 2 accommodated in the accommodating cavity 11, so that the aerosol flowing out from the accommodating cavity 11 has a flavor. The aerosol with the flavor is mixed with the aerosol formed by the vaporization of the liquid aerosol-forming matrix flowing out from the diverging airway 14, so that a better taste can be obtained, which improves the user experience.

[0024] In some embodiments, the air inlet A and the air outlet B are respectively located on two ends of the diverging vaporization module 1. The air inlet A and the air outlet B may be respectively located in the centers of the two ends of the diverging vaporization module 1. As shown in FIG. 1 to FIG. 3, from the perspective of projection, 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 side surfaces (not shown) of the two ends of the diverging vaporization module 1, or the air inlet A and the air outlet B may also be respectively located on side walls (not shown) of the accommodating cavity 11 of the diverging vaporization module 1. In some embodiments, the air inlet A and the air outlet B are staggered circumferentially, allowing for more heat exchanges between the aerosol which flows in from the air inlet A and the aerosol which flows out from the air outlet B, thereby achieving a richer taste. In practice, the positions of the air inlet A and the air outlet B may be determined according to the specific structure and design of the electronic vaporization device, and is not limited in the present invention as long as the aerosol entering from the air inlet A can flow out respectively through the accommodating cavity 11 and the diverging airway 14.

[0025] In some embodiments, the heating component 12 surrounds the outer periphery of a side wall of the accommodating cavity 11. The heating component 12 may adopt resistive heating, infrared heating, electromagnetic heating, etc. The resistive heating may be realized by wrapping the accommodating cavity by a flexible printed circuit (FPC), or by printing a heating thick film outside the accommodating cavity 11. In addition, the heating component 12 may also be arranged in segments along an axial direction of the accommodating cavity 11 to realize segment-wise heating, and so on, which is not limited in the present invention. The accommodating cavity 11 may be made of a metal with high thermal conductivity, such as stainless steel. Further, the thermal insulation component 13 surrounds the outer periphery of the heating component 12 to achieve more uniform heating.

[0026] In some embodiments, the diverging airway 14 is located on the outer periphery of the thermal insulation component 13 to prevent interference from the temperature of gas in the diverging airway 14 and the temperature of gas in the accommodating cavity 11 to affect the temperature of the aerosol in the diverging airway 14. In some other embodiments, the diverging airway 14 may also be arranged between the thermal insulation component 13 and the heating component 12, so that the thermal insulation component 13 can isolate the heat generated by the heating component 12, so as to prevent the temperature of the shell of the electronic vaporization device from being excessively high to affect the user experience.

[0027] In some embodiments, an isolation pipe 15 is further sleeved outside the thermal insulation component 13, a housing 16 is sleeved outside the isolation pipe 15, and the diverging airway 14 is formed between the housing 16 and the isolation pipe 15. Such a configuration not only can prevent the gas in the diverging airway 14 from being affected by other devices, but also can prevent the heat from being conducted to the shell, thereby preventing the temperature of the shell from being excessively high to affect the user experience.

[0028] In some embodiments, an air inlet hole 141 and an air outlet hole 142 respectively in communication with the air inlet A and the air outlet B are respectively arranged on the two ends of the diverging airway 14, to allow the gas to flow smoothly.

[0029] In some embodiments, pores are provided on a side wall of a container which defines the accommodating cavity 11, and the diverging vaporization module 1 further includes a flow cavity C in communication with the diverging airway 14 and the air outlet B. The aerosol entering the accommodating cavity 11 and the aerosol formed by the vaporization of the aerosol-forming matrix 2 may enter the flow cavity C through the pores, and then mixed in the flow cavity C, to provide a better taste of the aerosol to the user.

[0030] In some embodiments, during use, the diverging vaporization module 1 is installed on a vaporizer, so that the air inlet is in communication with an outlet on the vaporizer. The aerosol-forming matrix 2 is inserted into the accommodating cavity 11. The aerosol produced by the vaporizer heating the aerosol-forming matrix 2 flows into the diverging vaporization module 1 through the air inlet A. The aerosol partly enters the diverging airway 14, and partly enters the accommodating cavity 11 to heat a plant-grass like substance such as the aerosol-forming matrix 2 in the accommodating cavity 11, so as to form a mixed aerosol containing an effective substance of the aerosol-forming matrix 2.

[0031] In addition, the heating component 12 can generate heat to heat the aerosol-forming matrix 2 after being electrified. Different heating temperatures may be selected to control the amount of effective substance such as nicotine released from the aerosol-forming matrix 2, to achieve a steadier release of the effective substance in the entire vaporization stage.

[0032] It may be understood that, in the embodiment where pores are provided on the side wall of the container which defines the accommodating cavity 11, the aerosol in the accommodating cavity 11 flows into the flow cavity C through the pores and is mixed with the aerosol flowing through the diverging airway, so that the mixed aerosol provides a steady amount of effective substance, thereby achieving a better taste.

[0033] It may be understood that the diverging vaporization module 1 may be used in combination with a specially designed aerosol-forming matrix 2, so as to achieve diverging and mixing. FIG. 4 is a schematic diagram of the diverging vaporization module 1 installed in an electronic vaporization device and accommodating the aerosol-forming matrix 2 according to an embodiment of the present invention. Circulation holes 21 for the gas in the diverging airway 14 to flow out are provided on a side wall of the aerosol-forming matrix 2. The gas flowing out from the diverging airway 14 and the gas flowing through the accommodating cavity 11 are mixed in the aerosol-forming matrix 2 to form a mixed aerosol. Since the temperatures and the concentrations of the aerosol flows mixed in the aerosol-forming matrix 2 are different, a negative pressure is formed in the aerosol-forming matrix 2, so that the effective substance such as nicotine can be better carried. In addition, the mixing of the two flows can harmonize the taste and make the taste smoother.

[0034] Further, the circulation holes 21 are distributed along a circumferential direction of the aerosol-forming matrix 2, so that the gas flowing out from diverging airway 14 enters a cigarette 17 from a circumference of the aerosol-forming matrix 2, making the mixing more uniform.

[0035] Further, the diverging vaporization module 1 may further include a temperature control assembly 18 configured to control a temperature of the heating component 12. A target temperature of heating may be adjusted according to the user's needs. The temperature control assembly 18 may include only a signal receiver, which is configured to receive a preset signal from a battery end for control, or receive a set temperature inputted by the user through keys or a screen after being powered by a battery.

[0036] It may be understood that an adjusting component may be arranged additionally on the air inlet end of the diverging vaporization module 1. The adjusting component is configured to adjust an amount of the aerosol flowing through the diverging airway 14 and an amount of the aerosol flowing through the accommodating cavity 11. By adjusting the amount of the aerosol generated from the plant-grass like substance such as the aerosol-forming matrix 2, the aerosol flavor can be adjusted to better satisfy the user's needs.

[0037] According to the embodiments of the diverging vaporization module of the present invention, vapor produced by an electronic vaporization device partly flows into the accommodating cavity through the air inlet at the bottom of the accommodating cavity so as to vaporize a plant-grass like substance such as the aerosol-forming matrix in the accommodating cavity, and partly flows out of the air outlet through the diverging airway. The two parts of the aerosol are mixed for the user to inhale. The mixed aerosol provides a steady amount of effective substance and tastes good, which improves the user experience.
