With continued reference to fig. 5, fig. 5 shows a schematic perspective view of the bracket 13 in one direction, as well as with reference to fig. 2. The bracket 13 defines a containing chamber 131, the atomizing element 15 is contained in the containing chamber 131, meanwhile, in order to keep the atomizing element 15 in the containing chamber 131, the atomizer 10 further comprises the atomizing element silica gel piece 14, the atomizing element silica gel piece 14 is tightly sleeved on the atomizing element 15 and is in interference fit with the inner wall of the containing chamber 131, and the atomizing element silica gel piece 14 can keep the atomizing element 15 in the containing chamber 131 on one hand and can seal an assembly gap between the atomizing element 15 and the inner wall of the containing chamber 131 on the other hand.

The top of the bracket 13 defines a first liquid guiding hole 132, the first liquid guiding hole 132 is in fluid communication with the liquid storage cavity 18 through the fourth liquid guiding hole 161, the cavity wall of the accommodating cavity 131 defines a second liquid guiding hole 1311, the second liquid guiding hole 1311 is in fluid communication with the first liquid guiding hole 132, the atomizing element silica gel 14 is defined with a third liquid guiding hole 141, the third liquid guiding hole 141 is in fluid communication with the second liquid guiding hole 1311, and thus the liquid matrix in the liquid storage cavity 18 can flow to the atomizing element 15 through the fourth liquid guiding hole 161, the first liquid guiding hole 132, the second liquid guiding hole 1311 and the third liquid guiding hole 141 for atomization, as shown by the route R1 in fig. 2.

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 first heating element 1511 such that the first 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 first heating element 1511 on the atomizing surface 151 heats and atomizes the first liquid matrix, so that aerosol for inhalation by a user 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 invention, the atomizing element 15 may be other atomizing methods commonly used by those skilled in the art, and only the first heating element needs to be oriented to the accommodating 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 first 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 the first heating element to heat the first liquid matrix, and in order to conduct the first liquid matrix to the first 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 first heating element.

Further, since the first 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 first 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 prevent the fingers of the child from extending into the housing cavity and touching the first 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, and the aerosol generated after the first liquid substrate is atomized is released in the atomizing chamber 152, as can be seen from fig. 3, the first 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 housing cavity 111 and the atomizing chamber 152.

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 invention, 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 invention, 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 flavor releasing device 20 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 first 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 first heating element 1511. The first conductive electrode 17 is adapted to be electrically connected to a power supply mechanism (not shown) such that the power supply mechanism may provide electrical power to the aerosol-generating system 100 via the first conductive electrode 17, thereby allowing the first heating element 1511 to obtain electrical power required for heating via the first conductive electrode 17. Specifically, the bracket 13 further defines a second through hole 133, a portion of the first conductive electrode 17 is bent and extends into the accommodating chamber 131 through the second through hole 133, and is electrically connected to the first heating element 1511, and the first conductive electrode 17 extending into the accommodating chamber 131 is electrically connected to the first 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 taste piece 23 and a filter cotton 24, wherein the air passage pipe 22 extends in the shell 21 along the length 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 flavor member 23 is filled between the outer wall of the airway tube 22 and the inner wall of the housing 21, and the flavor member 23 stores a second liquid matrix that can release a specific flavor. .

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 air duct 22, a plurality of third through holes 221 are formed in the wall of the air duct 22, and the third through holes 221 are uniformly distributed on the wall of the air duct 22, and since the flavor member 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 flavor piece 23 contacts with the high-temperature aerosol through the third air inlet 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 air inlet hole 221, and the smell released by the flavor piece 22 can be carried to escape to the air outlet hole 211 after the aerosol enters the air passage pipe 22 through the first air inlet hole 212, so that a user can inhale the aerosol with the flavor.

It is to be understood that, in other embodiments of the present invention, only one third through hole 221 may be formed on the wall of the air duct 22, and only the smell of the flavoring element 23 needs to be released into the air duct 22. In this embodiment, the third through holes 221 are formed, so that the aerosol can transfer heat to the flavor member 23 in multiple directions, and the flavor member 23 can be heated and volatilized in multiple directions to generate more smell to be released into the air passage tube 22, so that a stronger flavor can be perceived during suction. 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 flavor member 23, and the flavor member 23 is uniformly heated. In addition, the third through hole 221 is disposed near the distal end of the flavor releasing device 20 to facilitate sealing of the flavor releasing device when transporting or storing the flavor releasing device 20, for example, the flavor liquid in the flavor element 20 can be prevented from leaking out of the third through hole 221 by directly plugging the third through hole 221 from the first air inlet hole 212 through a silicone plug.

When the flavor releasing device 20 is accommodated in the accommodating cavity 111, the flavor releasing device 20 abuts against the abutting portion 1112 in the accommodating cavity 111, so that a gap 1113 exists between the flavor releasing device 20 and the baffle 1111, the first air inlet hole 212 is in fluid communication with the gap 1113, aerosol in the atomizing chamber 152 enters the gap 1113 through the first through hole 11111, and then enters the airflow channel of the flavor releasing device from the gap 1113 through the first air inlet hole 212, so that the atomizing chamber 152 is in fluid communication with the airflow channel of the flavor releasing device 20. As can be seen from the aerosol transport path shown at R2 in fig. 3, 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 invention, 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 can volatilize under the action of the high-temperature aerosol and enter the air duct 22 together with the aerosol.

It should be noted that, in other embodiments of the present invention, 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 make the aerosol flow through the flavor releasing device 20 to take out the smell of the flavor element 23, the distal housing of the flavor releasing device 20 is provided with a second air inlet hole 213, the second air inlet hole 213 is distributed at two sides of the first air inlet hole 212, at least a part of the flavor element 23 is filled between the second air inlet hole 213 and the third air inlet hole 221, so that at least a part of the aerosol can enter the flavor releasing device 20 through the second air inlet hole 213 and pass through a part of the flavor element 23 to enter the air channel 22 from the third air inlet hole 221 to form a first air channel, at this time, the third air inlet hole 221 can also be called an aerosol outlet, and the aerosol is communicated with the air channel of the flavor releasing device 20 through the outlet, that is, is communicated with the pipeline of the air channel 22 of the flavor releasing device. 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 flavor releasing device 20 is divided into a first air passage and a second air passage, a part of flavor piece 23 is arranged on the air passage of the first air passage, and the second air passage avoids the flavor piece 23. It is easy to understand that, because the first airflow channel is provided with a part of the flavor member 23, the aerosol can directly pass through the flavor member 23, so that on one hand, the flavor member 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 invention, 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 taste piece 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.

The liquid guide 25a extends into the holding medium 23a partially, and extends into the pipeline of the air passage pipe 22a through the pipe wall of the air passage pipe 22a partially, and the liquid guide 25a is used for conducting the second liquid matrix in the holding medium 23a to the second heating element 26a for heating; the second heating element 26a is disposed on the liquid guiding member 25a and is located in the pipe of the air duct 22a, and the second heating element 26a is used for heating the second liquid matrix of the liquid guiding member 25a to volatilize the second liquid matrix under heating to generate a specific odor; the second conductive electrode 27a is electrically connected to the second heating element 26a for supplying the second heating element 26a with electric energy required for heating.

With respect to the above-mentioned airway tube 22a, please continue to refer to fig. 9 and 10, fig. 9 and 10 show perspective views of the airway tube 22a in two directions.

The wall of the air duct 22a is also provided with a slit 223a for communicating the fourth through hole 221 and the fifth through hole 222a, so that the second heating element 26a is conveniently mounted on the liquid guiding member 25a through the slit 223 a. The air duct 22a is configured as a part of the air flow channel of the taste releasing device 20a, and the second heating element 26a is arranged in the pipeline of the air duct 22a, so that the volatilized smell of the second liquid matrix of the liquid guide 25a heated by the second heating element 26a is directly released into the pipeline of the air duct 22a, and the aerosol generated by the atomizer 10a can directly bring out the smell released by the second liquid matrix after entering the air flow channel of the taste releasing device 20, thereby effectively improving the sucking taste.

With continued reference to fig. 11, fig. 11 shows a schematic perspective view of the liquid guiding member 25 in one direction. The liquid guide 25a is made of a fibrous material having hygroscopicity, and is generally elongated in shape, such as cotton fiber, nonwoven fabric, glass fiber rope, or the like, or the liquid guide 25a may be a porous body having a microporous structure, such as porous ceramic, or the like, and the second heating element 26a may be bonded to the liquid guide 25 by printing, deposition, sintering, physical assembly, or the like, or wound around the liquid guide 25. For example, if the liquid guide 25 is a porous ceramic, the second heating element 26a may be printed on the surface of the porous ceramic. In this embodiment, for reducing cost and simplifying structure, the liquid guiding member 25 is a cotton rope structure made of cotton fibers, and the second heating element 26a is a resistance heating wire wound on the liquid guiding member 25 a.

The second conductive electrode 27a is electrically connected to the second heating element 26a, and at least a portion of the second conductive electrode 27a protrudes from the distal end surface of the flavour release device 20a and extends away from the distal end surface, so that when the flavour release device 20a is received in the receiving cavity 111a of the atomizer 10a, the second conductive electrode 27a protruding from the distal end surface of the flavour release device 20a can be electrically connected to the first conductive electrode 17a of the atomizer 10a through the first through hole 11111a of the baffle 1111a of the atomizer 10a, and further the second heating element 26a is parallel connected to the first heating element 1511a, and when the first conductive electrode 17a is electrically connected to the power supply mechanism, the power supply mechanism can supply electric energy to the first heating element 1511a through the first conductive electrode 17a and the second conductive electrode 27a, and at the same time can supply electric energy to the second heating element 26a, so that the first heating element 1511a and the second heating element 26a can generate heat at the same time.

Therefore, in the embodiment, by providing the independent second heating element 26a on the taste releasing device 20a, and connecting the second heating element 26a in parallel with the first heating element 1511a in the atomizer 10a, when the atomizer 10a is electrically connected with the external power supply structure, the external power supply mechanism can simultaneously supply power to the first heating element 1511a and the second heating element 26a, so that the first heating element 1511a and the second heating element 26a generate heat simultaneously, the liquid perfume in the taste releasing device 20a can be fully atomized and volatilized, the taste is more intense, and the sucked taste is effectively improved. It will be readily appreciated that to facilitate electrical connection of the first conductive electrode 17a with the second conductive electrode 27a when the flavour release device 20a is received in the receiving cavity 111a, the first heating element 1511a is configured to face the receiving cavity 111a in an axial direction of the aerosol-generating system 100a to facilitate electrical connection of the first conductive electrode 17a with the second conductive electrode 27 a.

It should be noted that, in other embodiments of the present invention, the taste releasing device 20a may also be heated by other ways. For example, an electromagnetic induction coil may be disposed around the outer wall of the housing cavity 111a, and the electromagnetic induction coil is electrically connected to the first conductive electrode 17a, and a susceptor, which is a second heating element of the taste releasing device 20a, is disposed on the liquid guiding member 25 a. When the first conductive electrode is connected to an external power source, the first conductive electrode 17a provides electrical energy to the first heating element 1511a to cause the first heating element 1511a to heat the first liquid matrix. Meanwhile, an alternating current is supplied to the electromagnetic induction coil, and the alternating current generates a changing magnetic field in the accommodating cavity 111a, so that an eddy current can be induced on the susceptor because the susceptor is positioned in the accommodating cavity 111a, and the susceptor can generate heat under the generation of the eddy current, so that the second liquid matrix on the liquid guide 25a can be heated. Alternatively, the second heating element may be heated by other means, and the second heating element may be activated only when the first heating element 1511a is activated.

Further, as in the previous embodiment, the bracket 13a of the atomizer 10a is defined with a second through hole 133a, a portion of the first conductive electrode 17a is bent and extends into the atomizing chamber 152a through the second through hole 133a, and is electrically connected to the first heating element 1511a, and the first conductive electrode 17a extending into the atomizing chamber 152a is electrically connected to the first heating element 1511a by means of a spring. When the flavor releasing device 20 is accommodated in the accommodating cavity 111a, the second conductive electrode 27a elastically abuts against the elastic sheet and provides a pressing force to the elastic sheet, the elastic sheet deforms and generates a reverse pressing force to the second conductive electrode 27a under the deformation restoring force, so that good electrical contact between the first conductive electrode 17a and the second conductive electrode 27a is ensured.

Further, in order to facilitate the electrical connection between the second conductive electrode 27a and the first conductive electrode 17a, the elastic sheet is disposed directly under the first through hole 11111a, that is, the first through hole 11111a is opposite to the elastic sheet, so that the second conductive electrode 27a can be electrically connected to the first conductive electrode 17a after vertically passing through the first through hole 11111 a.
