The smoke liquid of the electronic atomization device usually has only one specific taste, and a user cannot obtain experiences of different tastes in the same electronic atomization device.

In the prior art, the above technical problem is solved by a flavor releasing device separated from an electronic atomizing device main body, no flavor is added in smoke liquid of the electronic atomizing device, the flavor releasing device is inserted into the electronic atomizing device main body when in use, and the flavor in the flavor releasing device is brought out by aerosol generated by the electronic atomizing device, so that different atomized flavors can be obtained by replacing the flavor releasing device, but the flavor in the flavor releasing device is not fully volatilized, so that the taste is not good enough when in suction.

The atomizing element 15 is a porous body having a microporous structure therein, such as a porous ceramic, the porous body being configured to be substantially in the shape of, but not limited to, a block structure in the embodiment, which includes an arch shape according to a preferred design of the present embodiment, and its specific structure is described in patent application CN 212590248U. In a generally functional configuration, the porous body has an atomizing face 151 facing the receiving chamber 111 and a liquid-absorbing face (not shown) facing away from the atomizing face 151, the atomizing face 151 being provided with a heating element 1511 such that the heating element 1511 is also facing the receiving chamber 111. The porous body has a microporous structure (not shown) therein for conducting the first liquid matrix, the first liquid matrix flows from the liquid storage cavity 18 to the atomizing element 15 to be absorbed by the liquid absorbing surface of the atomizing element 15, then the first liquid matrix is conducted to the atomizing surface 151 through the microporous structure of the porous body, and the heating element 1511 on the atomizing surface 151 heats and atomizes the first liquid matrix, so that aerosol for the user to inhale is generated.

It should be noted that, the configuration of the atomizing element 15 is not limited to this, and in other embodiments of the present application, the atomizing element 15 may be other atomizing methods commonly used by those skilled in the art, and only the heating element 1511 needs to be oriented to the housing cavity 111 in the axial direction of the atomizer 10. For example, the atomizing element 15 may be a flat porous body (not shown) having opposite upper and lower surfaces, the upper surface being configured as an atomizing surface, the atomizing surface being also directed toward the housing chamber 111. The lower surface of the porous body is covered with liquid-guiding cotton (not shown), the heating element 1511 is disposed on the atomizing surface of the porous body, the liquid-guiding cotton is used for absorbing the liquid matrix and transmitting the absorbed liquid matrix to the porous body, and the microporous structure of the porous body transmits the liquid matrix to the atomizing surface. Alternatively, the atomizing element 15 may not be in the form of a porous body, for example, the atomizing element 15 may atomize the first liquid matrix by using liquid-guiding cotton in combination with a flat metal heating mesh, the metal heating mesh serves as a heating element to heat the first liquid matrix, and in order to conduct the first liquid matrix to the heating element for heating, the flat metal heating mesh may be covered with liquid-guiding cotton, the first liquid matrix in the liquid storage cavity 18 may flow onto the liquid-guiding cotton, and the liquid-guiding cotton further conducts the first liquid matrix to the heating area of the heating element.

Further, since the heating element 1511 faces the housing cavity 111, in order to prevent the fingers of the child from extending into the housing cavity 111 and touching the heating element 1511 to generate a risk of scalding, a baffle 1111 is disposed at the bottom of the housing cavity 111, the baffle 1111 is circumferentially connected to the inner wall of the housing cavity 111 to block the fingers of the child from extending into the housing cavity and touching the heating element 1511, the baffle 1111 and the atomizing surface 151 of the atomizing element 15 define the atomizing chamber 152 of the atomizer 10, the aerosol generated after the first liquid substrate is atomized is released in the atomizing chamber 152, and as can be seen from fig. 3, the heating element 1511 and the housing cavity 111 are distributed on opposite sides of the atomizing chamber 152, and the baffle 1111 is used for separating the atomizing chamber 152 and the housing cavity 111.

Further, in order to guide the aerosol generated after atomization into the flavor releasing device 20, the baffle 1111 is provided with a plurality of first through holes 11111, and the plurality of first through holes are uniformly distributed on the baffle 1111, so that the aerosol can enter the accommodating cavity 111 through the first through holes 11111, and thus enter the flavor releasing device 20. It is easy to understand that in other embodiments of the present application, only one first through hole 1111 may be formed, and in this embodiment, forming a plurality of first through holes 11111 is beneficial to enabling the aerosol to smoothly enter the accommodating cavity 111, and uniformly distributing the plurality of first through holes 11111 on the baffle is more beneficial to enabling the aerosol to smoothly enter the accommodating cavity 111, so as to effectively reduce turbulence of the aerosol.

It should be noted that, the arrangement of the baffle 1111 is not limited to this, and in other embodiments of the present application, the baffle 1111 may not be circumferentially connected to the inner wall of the accommodating chamber 111, but may span the inner wall of the accommodating chamber 111 in the radial direction, so that a certain gap is kept between the baffle 1111 and the inner wall of the accommodating chamber 111, and the aerosol may enter the accommodating chamber 111 through the gap.

Further, an abutment portion 1112 is further provided at the bottom of the accommodating cavity 111, and the abutment portion 1112 is configured to abut against the distal end of the flavor releasing device 20, so as to limit the flavor releasing device 20 when accommodated in the accommodating cavity 111. The abutment 1112 comprises an abutment boss extending from the surface of the baffle 1111 towards the proximal direction of the atomizer 10, such that a certain gap 1113 is maintained between the abutment 1112 and the baffle 1111 in the axial direction of the atomizer 10, i.e. such that a gap 1113 exists between the flavour release means 20 and the baffle 1111, and aerosol flows through the through hole 11111 into the gap 1113 and from the gap 1113 into the flavour release means 20.

For the above-mentioned conductive electrode 17, a part thereof is fixedly mounted on the base 12, and the other part extends into the accommodating chamber 131 to be electrically connected with the heating element 1511. The conductive electrode 17 is adapted to be electrically connected to a power supply mechanism (not shown) so that the power supply mechanism can supply power to the atomizer 100 via the conductive electrode 17 and so that the heating element 1511 can obtain the power required for heating via the conductive electrode 17. Specifically, the bracket 13 further defines a second through hole 133, a portion of the conductive electrode 17 is bent and extends into the accommodating chamber 131 through the second through hole 133, and is electrically connected to the heating element 1511, and the conductive electrode 17 extending into the accommodating chamber 131 is electrically connected to the heating element 1511 by means of a spring plate.

With respect to the flavor releasing device 20 described above, with continued reference to fig. 6, fig. 6 shows a schematic perspective view of the flavor releasing device 20 in one direction, the flavor releasing device 20 having a proximal end and a distal end opposite in length, the proximal end defining an air outlet 211 for the aerosol to escape the flavor releasing device 20, and the distal end defining a first air inlet 212 for the aerosol to enter the flavor releasing device 20.

The taste releasing device 20 comprises a shell 21, an air passage pipe 22, a holding medium 23 and a filter cotton 24, wherein the air passage pipe 22 extends in the shell 21 along the axial direction of the taste releasing device 20, two ends of the air passage pipe 22 are provided with openings, one end of the air passage pipe 22 extends to the far end of the taste releasing device 20 and is in fluid communication with the first air inlet hole 212, and the other end of the air passage pipe is in fluid communication with the air outlet hole 211; the filter cotton 24 is arranged between the air outlet hole 211 and the air passage pipe 22 and is used for filtering large particulate matters in aerosol smoke, and meanwhile, condensate formed after the aerosol is condensed can be filtered out, so that the sucked aerosol smoke is finer and finer, and the suction taste is effectively improved; the holding medium 23 is filled between the outer wall of the airway tube 22 and the inner wall of the housing 21, the holding medium 23 storing a second liquid matrix that can release a specific taste. .

The holding medium 23 is made of a material having hygroscopicity, and may be, for example, glass fiber, cotton fiber, nonwoven fabric, or the like, and the second liquid matrix may be adsorbed in the holding medium 23 because the holding medium 23 has hygroscopicity. In this embodiment, the holding medium 23 is cotton, and the second liquid matrix can be stored in the taste releasing means 20 by filling the cotton-like holding medium 23 between the outer wall of the airway tube 22 and the inner wall of the housing 21.

For the above-mentioned air duct 22, the wall of the air duct 22 is provided with a plurality of third through holes 221, and the third through holes 221 are uniformly distributed on the wall of the air duct 22, and since the holding medium 23 is filled between the outer wall of the air duct 22 and the inner wall of the housing 21, a part of the holding medium can be exposed in the pipe of the air duct 22 through the third through holes 221. The high-temperature aerosol enters the air passage pipe 22 through the first air inlet hole 212, the holding medium 23 contacts with the high-temperature aerosol through the third through hole 221 and volatilizes under the action of high temperature, the volatilized smell can be released into the pipeline of the air passage pipe 22 through the third through hole 221, and after the aerosol enters the air passage pipe 22 through the first air inlet hole 212, the smell released by the holding medium 22 can be carried to escape to the air outlet hole 211, so that a user can inhale the aerosol with taste. It is to be understood that, in other embodiments of the present application, only one third through hole 221 may be formed on the wall of the air passage tube 22, and only the odor of the retaining medium 23 needs to be released into the air passage tube 22.

In this embodiment, a plurality of third through holes 221 are formed, so that the aerosol can transfer heat to the holding medium 23 in a plurality of directions, and further the holding medium 23 can be heated and volatilized in a plurality of directions to generate more smell to be released into the air passage tube 22, so that a stronger taste can be felt during suction. And the third through holes 221 are uniformly distributed on the wall of the air passage pipe 22, so that the heat of the aerosol can be uniformly transferred to the holding medium 23, and the holding medium 23 is uniformly heated. In addition, the third through hole 221 is disposed near the distal end of the taste releasing means 20 to facilitate sealing of the taste releasing means when transporting or storing the taste releasing means 20, for example, the taste releasing means may be plugged directly through a silicone plug from the first air inlet hole 212 so that the third through hole 221 may be sealed, preventing the taste liquid in the holding medium 20 from leaking out of the third through hole 221.

When the flavour release device 20 is received in the receiving cavity 111, the distal end of the flavour release device 20 abuts against the abutment 1112 in the receiving cavity 111 such that a gap 1113 is present between the flavour release device 20 and the baffle 1111, the first air inlet aperture 212 is in fluid communication with the gap 1113, aerosol in the atomising chamber 152 enters the gap 1113 through the first through aperture 11111 and then enters the airflow channel of the flavour release device from the gap 1113 through the first air inlet aperture 212 such that the atomising chamber 152 is in fluid communication with the airflow channel of the flavour release device 20. As can be seen from the aerosol transport path shown at R2 in fig. 2, the receiving chamber 111 is downstream of the heating element 1511 in the direction of airflow travel.

In addition, in other embodiments of the present application, the axial distance that the holding medium 23 extends between the outer wall of the air duct 22 and the inner wall of the housing 11 is greater than the axial extension of the air duct 22, so that at least a portion of the holding medium 23 is exposed to the aerosol transmission path, and after the high-temperature aerosol generated by the atomization of the atomizer 100 enters the accommodating cavity 111, the holding medium 23 can contact with the exposed holding medium 23, and the holding medium 23 is partially volatilized under the action of the high-temperature aerosol and enters the air duct 22 together with the aerosol.

It should be noted that, in other embodiments of the present application, when the flavor releasing device 20 is accommodated in the accommodating cavity 111, the flavor releasing device 20 may be directly abutted against the baffle 1111, that is, there is no gap 1113 between the flavor releasing device 20 and the baffle 1111, and at this time, the aerosol in the atomizing chamber 152 may also directly enter the airflow channel of the flavor releasing device 20 through the first through hole 11111 and the first air inlet 212, but part of the aerosol may be blocked by the baffle, so that the amount of smoke is not strong enough during the suction. In this embodiment, a gap 1113 is provided between the taste releasing device 20 and the baffle 1111, and aerosol can flow into the gap 1113 during suction, and then enter the airflow channel of the taste releasing device 20 from the gap 1113 through the first air inlet hole 212, so that the amount of smoke during suction is more intense, and the suction taste is improved.

Further, in order to better carry out the smell of the holding medium 23 when the aerosol flows through the taste releasing device 20, the distal housing of the taste releasing device 20 is provided with second air inlet holes 213, the second air inlet holes 213 are distributed on both sides of the first air inlet holes 212, and at least a part of the holding medium 23 is filled between the second air inlet holes 213 and the third air inlet holes 221, so that at least a part of the aerosol can enter the taste releasing device 20 through the second air inlet holes 213 and pass through a part of the holding medium 23 to enter the air channel tube 22 from the third air inlet holes 221 to form a first air flow channel, and at this time, the third air inlet holes 221 can be also called aerosol outlet, and the aerosol can enter the air channel of the air channel tube 20 of the taste releasing device 20 through the outlet. At least a part of aerosol directly enters the air passage pipe 22 through the first air inlet hole 212 to form a second air passage, so that the air passage of the taste releasing device 20 is divided into a first air passage and a second air passage, a part of the holding medium 23 is arranged on the air passage of the first air passage, and the second air passage avoids the holding medium 23. It is easy to understand that, because the first airflow channel is provided with a part of the holding medium 23, the aerosol can directly pass through the holding medium 23, so that on one hand, the holding medium 23 can be heated more fully and volatilized better; on the other hand, the volatile smell can be fully taken away, so that the taste is more intense. It is to be understood that, in other embodiments of the present application, only one second air inlet hole 213 is required, and in this embodiment, a plurality of second air inlet holes 213 are provided, and the second air inlet holes 213 are distributed on two sides of the first air inlet hole 212, so that the entering aerosol enters the taste releasing device 20 from multiple directions through the second air inlet holes 213, and the holding medium 23 is heated more uniformly, so that the taste of the sucked food is better.

In some embodiments, the proximal end of the flavour release device 20 may extend outside the receiving cavity 111 as a mouthpiece of an aerosol generating system and at the proximal end there is defined an outlet aperture 211 for the aerosol discharge, where the user may directly inhale through the flavour release device 20 without the need for additional mouthpiece.

According to the above description, since the heating element 1511 of the atomizer 10 is adjacent to the taste releasing means 20 when the taste releasing means 20 is accommodated in the atomizer 10, the heat released by the heating element 1511 can be better transferred to the holding medium 23 of the taste releasing means 20, and the second liquid medium of the holding medium 23 can be volatilized more sufficiently with the heat sufficient. And the high-temperature aerosol generated by heating the first liquid matrix by the heating element 1511 in the atomizer 10 can pass through or flow through the holding medium 23, so that more taste released by the second liquid matrix can be taken away when the aerosol passes through the holding medium 23, and the taste can be more intense when the aerosol is sucked by a user, and the sucking taste is better.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application, and are not limiting; the technical features of the above embodiments or in the different embodiments may also be combined within the idea of the application, the steps may be implemented in any order, and there are many other variations of the different aspects of the application as described above, which are not provided in detail for the sake of brevity; although the application has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the application.
