Description

TECHNICAL FIELD

[0002] The aerosol generating device is a kind of electronic product that atomizes aerosol generating liquid to generate aerosol for users to smoke.

The existing aerosol generating device includes a shell, an atomization assembly, a battery and an airflow sensor arranged in the shell. The aerosol generating device detects the smoking action of the user through the airflow sensor to control the power supply of the battery, so that the heating element in the atomization assembly generates heat, and the aerosol generating liquid in the atomization assembly is atomized to form aerosol.

[0003] In the existing aerosol generating device, the airflow sensor and the battery are usually installed at the end of the atomization assembly away from the user, the atomization assembly is located between the user and the airflow sensor, and the battery is coaxially arranged with the atomization assembly. However, when the aerosol generating device is placed vertically or the user smokes the aerosol generating device, the condensed liquid formed by the condensation of the aerosol is easy to flow into the airflow sensor. The condensed liquid and the leaked aerosol generating liquid not only block the airflow sensor, causing the airflow sensor to fail, but also cause the aerosol generating device to be unable to start, resulting in a short service life of the aerosol generating device. In addition, after smoking, part of the aerosol will condense in the mist outlet hole of the mouthpiece to form condensed liquid.

[0034] Please refer to Figures 1 to 6 The present application discloses an aerosol generating device, which comprises a body 100 and a mouthpiece cover 200, the body 100 comprising a mouthpiece 1, a shell 2, a sealing top cover 3, a first atomization assembly 4, a second atomization assembly 5, an airflow sensor 6 and an air path blocking assembly 7, the mouthpiece 1 being connected to the shell 2, the mouthpiece 1 being provided with an aerosol outlet hole 11 for discharging the aerosol generated by the first atomization assembly 4 to the outside of the aerosol generating device for the user to smoke.

[0035] The shell 2 is provided with an elastic reset member 8, i.e. the elastic reset member 8 is accommodated in the shell 2, and the elastic reset member 8 is connected to the air path blocking assembly 7. In this embodiment, the shell 2 is provided with a first cavity 201 and a second cavity 202 arranged side by side, and the first cavity 201 is communicated to the outside of the shell 2. The airflow sensor 6 is arranged in the mouthpiece 1 and located at the cavity opening of the first cavity 201, and the second cavity 202 accommodates a porous liquid absorbing body 91, which is used to absorb the aerosol generating liquid for atomization by the first atomization assembly 4. The porous liquid absorbing body 91 can be made of natural fibers, artificial fibers or ceramic materials.

[0036] In a preferred embodiment of the present application, the shell 2 comprises a first sleeve 21, a second sleeve 22 and a third sleeve 23, the second sleeve 22 is detachably arranged in the first sleeve 21, the first sleeve 21 and the second sleeve 22 form the first cavity 201, and the second sleeve 22 forms the second cavity 202. The first sleeve 21 is located in the third sleeve 23, and the third sleeve 23 and the first sleeve 21 form a tubular heat insulation gap, so as to avoid overheating of the third sleeve 23 in use. One end of the third sleeve 23 is connected with a bottom cover 24, and the bottom cover 24 is provided with an air inlet hole 241 communicating with the second atomization assembly 5. The mouthpiece 1 is connected with the first sleeve 21, the second sleeve 22 and the third sleeve 23, and the bottom cover 24 and the mouthpiece 1 are located at opposite ends of the third sleeve 23, respectively.

[0037] The sealing top cover 3 is located in the mouthpiece 1 and is sealingly connected with the shell 2, and the sealing top cover 3 is provided with a mounting groove 31, an air outlet groove 32, a plug hole 33, a connecting groove 34 and a fixing groove 35. The mounting groove 31 is used for mounting the airflow sensor 6 and is in communication with the air outlet groove 32. The air outlet groove 32 is used for communicating with the mist outlet hole 11. Specifically, the air outlet groove 32 is arranged to extend along the transverse direction of the aerosol generating device. The plug hole 33 is in communication with the air outlet groove 32, and the plug hole 33 is arranged to extend along the longitudinal direction of the aerosol generating device. The connecting groove 34 is located between the air outlet groove 32 and the fixing groove 35, the first end of the connecting groove 34 is in communication with the air outlet groove 32 and the plug hole 33, and the second end of the connecting groove 34 is in communication with the fixing groove 35. The air outlet groove 32 communicates with the mist outlet hole 11 through the connecting groove 34.

[0038] The airflow sensor 6 is mounted in the mounting groove 31 at the sealing top cover 3 and is in communication with the air outlet groove 32 to communicate with the mist outlet hole 11 through the air outlet groove 32. The height of the bottom wall of the air outlet groove 32 is higher than the height of the connecting groove 34, so that the condensate is not easy to flow into the air outlet groove 32 and into the airflow sensor 6. More preferably, a plurality of capillary grooves 321 are further arranged at the bottom wall of the air outlet groove 32, and the condensate is adsorbed through the capillary grooves 321, so as to further prevent the condensate from flowing into the airflow sensor 6. The sealing top cover 3 is further provided with an air inlet groove 36 in communication with the airflow sensor 6, and the air inlet groove 36 is located below the airflow sensor 6.

[0039] The first atomization assembly 4 is located in the shell 2. In the embodiment, the first atomization assembly 4 comprises a first liquid absorbing cotton column 41 and a first heating element 42. The first liquid absorbing cotton column 41 is located in and in contact with the porous liquid body 91. The first heating element 42 is located in and in contact with the first liquid absorbing cotton column 41, and is used to atomize the aerosol generating liquid in the first liquid absorbing cotton column 41. The first heating element 42 can be a heating wire or a heating sheet, and the structure thereof is not limited here.

[0040] The second atomization assembly 5 is located at the sealing top cover 3 and abuts against the orifice of the mist outlet hole 11. The second atomization assembly 5 is used to atomize the condensed liquid at the mist outlet hole 11. In the embodiment, the second atomization assembly 5 comprises a second liquid absorbing cotton column 51 and a second heating element 52. The second liquid absorbing cotton column 51 is in a cylindrical shape. The first end of the second liquid absorbing cotton column 51 is inserted into the fixing groove 35, and the second end of the second liquid absorbing cotton column 51 abuts against the orifice of the mist outlet hole 11, so that the condensed liquid flowing down from the mist outlet hole 11 can be well absorbed, and the condensed liquid can be prevented from flowing around.

[0041] Preferably, the center line of the second liquid absorbing cotton column 51 coincides with the center line of the mist outlet hole 11, and the aperture of the second liquid absorbing cotton column 51 is smaller than the aperture of the mist outlet hole 11. Thus, the condensed liquid can be well absorbed, and the aerosol generating liquid in the porous liquid body 91 can be prevented from being polluted by the condensed liquid. In order to prevent the condensed liquid from flowing into the porous liquid body 91, the second liquid absorbing cotton column 51 is spaced apart from the porous liquid body 91, so that the two are not in contact with each other.

[0042] In the embodiment, the second heating element 52 is located in and in contact with the second liquid absorbing cotton column 51, and is used to atomize the aerosol generating liquid in the second liquid absorbing cotton column 51. The second heating element 52 can be a heating wire or a heating sheet, and the structure thereof is not limited here. It can be understood that, in an embodiment, the second liquid absorbing cotton column 51 can be replaced by a porous ceramic, and thus the material thereof is not limited here, as long as the condensed liquid can be absorbed.

[0043] The nozzle cover 200 is provided with a liquid pushing plug 2001, and a silica gel ring 2002 is sleeved on the liquid pushing plug 2001. The nozzle cover 200 is detachably connected with the body 100. In the first state, the nozzle cover 200 is separated from the nozzle 1, and the air path blocking assembly 7 closes the air outlet groove 32, that is, when the present application is not used, the nozzle cover 200 is separated from the body 100, and under the elastic force of the elastic reset member 8, the air path blocking assembly 7 automatically closes the air outlet groove 32, thereby hindering the condensate from flowing towards the air flow inductor 6.

[0044] In the second state, the nozzle cover 200 is covered on the nozzle 1, and the liquid pushing plug 2001 is inserted into the mist outlet hole 11 to push the condensate in the mist outlet hole 11 to flow towards the second atomization assembly 5, and at the same time, the nozzle cover 200 drives the air path blocking assembly 7 to open the air outlet groove 32, so that the air outlet groove 32 is communicated with the mist outlet hole 11, and thus the user can normally use the present application. Therefore, the problem that the user easily inhales the condensate when smoking this time is avoided, because the residual aerosol is condensed in the mist outlet hole 11 to form the condensate when the user smokes last time. In order to avoid too much condensate remaining in the liquid pushing plug 2001, the length of the liquid pushing plug 2001 is less than one fourth of the length of the mist outlet hole 11, and specifically, the length of the liquid pushing plug 2001 is preferably within 2.5 mm.

[0045] In a preferred embodiment of the present application, the air path blocking assembly 7 comprises a blocking piece 71 and a first magnetic piece 72 connected with the blocking piece 71, the blocking piece 71 is connected with the elastic reset member 8 and movably connected with the sealing top cover 3. The nozzle cover 200 comprises a cover body 2003 and a second magnetic piece 2004 connected with the cover body 2003, and the liquid pushing plug 2001 is arranged in the cover body 2003. In the first state, the elastic reset member 8 drives the blocking piece 71 to close the air outlet groove 32. In the second state, the second magnetic piece 2004 and the first magnetic piece 72 repel each other magnetically, so that the air path blocking assembly 7 opens the air outlet groove 32.

[0046] That is, in the absence of the present application, the barrier 71 is pushed to close the air outlet slot 32 by the elastic force of the elastic reset member 8. When the mouthpiece cover 200 covers the mouthpiece 1, the air path barrier assembly 7 is driven by the repulsive force between the second magnetic member 2004 and the first magnetic member 72, so that the elastic reset member 8 is compressed, thereby causing the air path barrier assembly 7 to open the air outlet slot 32. It can be understood that the elastic reset member 8 can be a spring or a spring sheet, and its structure is not specifically limited here. In the present embodiment, the first magnetic member 72 and the second magnetic member 2004 are both magnets.

[0047] In a preferred embodiment of the present application, the aerosol generating device further comprises a push air plug 92 connected to the barrier 71; in the first state, the push air plug 92 is at least partially inserted into the air inlet slot 36, and in the second state, the push air plug 92 is spaced apart from the slot opening of the air inlet slot 36. That is, when the user finishes smoking and removes the mouthpiece cover 200, the elastic reset member 8 drives the barrier 71 to move towards the mouthpiece 1, and at the same time, the barrier 71 drives the push air plug 92 to insert into the air inlet slot 36. Therefore, during the process of the user finishing smoking and then removing the mouthpiece cover 200, the airflow in the air outlet slot 32 continues to flow towards the mist outlet hole 11 by the driving of the push air plug 92, avoiding the aerosol remaining in the mouthpiece 1 from flowing into the airflow inductor 6. In addition, when the barrier 71 moves to the preset position, it is separated from the airflow inductor 6 and the mist outlet hole 11. This structure is ingenious, low in cost, convenient to use, easy to implement, and good in effect.

[0048] Specifically, the barrier 71 comprises a connecting arm 711 extending in the horizontal direction, a fixed arm 712 extending in the horizontal direction, and a gas blocking arm 713 extending in the vertical direction, the connecting arm 711 is connected to the first end of the gas blocking arm 713 and the elastic reset member 8, and the push air plug 92 is fixed at the connecting arm 711. The gas blocking arm 713 extends into the insertion hole 33, and the fixed arm 712 is located in the connecting slot 34 and connected to the second end of the gas blocking arm 713. The first magnetic member 72 is fixed at the fixed arm 712. In the first state, the gas blocking arm 713 extends to one end of the air outlet slot 32 to cover the port of the air outlet slot 32 away from the airflow inductor 6, and in the second state, the gas blocking arm 713 is spaced apart from the air outlet slot 32 by a predetermined distance, so that the air outlet slot 32 is communicated with the connecting slot 34 to be communicated to the mist outlet hole 11. This structure has the advantages of easy manufacturing and high production efficiency.

[0049] Preferably, the cross-sectional area of the push air plug 92 is equal to that of the air inlet groove 36, and the distance between the push air plug 92 and the top wall of the air inlet groove 36 is greater than that between the air blocking arm 713 and the plane of the slot opening of the air outlet groove 32 away from the shell 2. In the embodiment, the distance between the push air plug 92 and the top wall of the air inlet groove 36 is L1, and the distance between the air blocking arm 713 and the plane of the slot opening of the air outlet groove 32 away from the first cavity 201 is L2, and L1>L2. That is, when the air blocking arm 713 completely blocks the air outlet groove 32 in use, the elastic return member 8 continues to push the connecting arm 711 to move for a preset time, so that the air pressure at the air flow sensor 6 is greater than that at the mist outlet hole 11. Therefore, even if there is excessive condensed liquid, it is not easy to seep into the air flow sensor 6 from the connecting groove 34. This structure can better avoid the problem that, during carrying, if the air pressure at the air flow sensor 6 is less than that at the mist outlet hole 11, the condensed liquid easily seeps into the air flow sensor 6 from the connecting groove 34.

[0050] In a preferred embodiment of the present application, the aerosol generating device further comprises a third magnetic member 93 and a fourth magnetic member 94. The third magnetic member 93 is fixed in the mouthpiece 1, and the fourth magnetic member 94 is fixed in the mouthpiece cover 200. In the second state, the third magnetic member 93 and the fourth magnetic member 94 are magnetically attracted to each other. Therefore, without a complex connecting structure between the mouthpiece cover 200 and the mouthpiece 1, reliable connection between the two can be achieved through the magnetic attraction of the third magnetic member 93 and the fourth magnetic member 94, which is not only convenient for users to use, but also has long service life and reliable connection.

[0051] Preferably, the repulsive force between the second magnetic member 2004 and the first magnetic member 72 is F1, and the attractive force between the third magnetic member 93 and the fourth magnetic member 94 is F2, and F2>F1. Therefore, the system has high reliability, and the production process is reduced, and the production efficiency is high. It can be understood that the third magnetic member 93 and the fourth magnetic member 94 can both be magnets, or one of them is a magnet and the other is a ferromagnetic material that can be attracted to a magnet.

[0052] In a preferred embodiment of the present application, the aerosol-generating device further comprises an elastic sealing sheet 95 located on the side of the sealing top cover 3 opposite to the first cavity 201 and covering the slot of the air outlet groove 32 to seal the slot on the side opposite to the first cavity 201. Therefore, when a user inhales, the airflow in the installation groove 31 area can quickly flow to the mist outlet hole 11, thereby quickly triggering the airflow sensor 6, so as to improve the sensitivity of the airflow sensor 6 and improve the user experience. In addition, this structure is convenient to manufacture, reduces the manufacturing process, and improves the production efficiency. It can be understood that in the first state, the air path blocking component 7 abuts against the elastic sealing sheet 95. It can be understood that in an embodiment, the elastic sealing sheet 95 can not be provided, and the slot of the air outlet groove 32 on the side opposite to the first cavity 201 elastically abuts against the mouthpiece 1. In the first state, the air path blocking component 7 abuts against the mouthpiece 1.

[0053] The aerosol-generating device further comprises a capacitor 96, a battery 97, and a controller 98. The capacitor 96 corresponds to the position of the second atomization component 5 and is used to detect the remaining amount of condensate in the second atomization component 5. The capacitor 96 comprises a first electrode plate 961 and a second electrode plate 962, which are oppositely arranged and located at the outer circumferential surface of the second atomization component 5. The first electrode plate 961 and the second electrode plate 962 are both electrically connected to the controller 98. The controller 98 calculates the remaining amount of condensate in the second atomization component 5 according to the capacitance of the capacitor 96. It can be understood that the condensate in the second atomization component 5 includes the condensate flowing down from the mouthpiece 1 and the condensate formed when the aerosol passes through the second atomization component 5.

[0054] The battery 97 and the controller 98 are both located in the first cavity 201. The battery 97 is electrically connected to the controller 98. The controller 98 is electrically connected to the airflow sensor 6, the first heating element 42, and the second heating element 52. After the user covers the mouthpiece 1 with the mouthpiece cover 200 to make the air path blocking component 7 open the air outlet groove 32, when the user inhales from the mouthpiece cover 200, the airflow sensor 6 is triggered. The controller 98 controls the first atomization component 4 to atomize the aerosol-generating liquid according to the trigger signal of the airflow sensor 6 to form aerosol for the user to inhale.

[0055] In a preferred embodiment of the present application, the aerosol generating device further comprises a fifth magnetic member 991, a Hall sensor 992, a first fan 993 and a second fan 994. The fifth magnetic member 991 is installed at the mouthpiece cover 200 and cooperates with the Hall sensor 992. The Hall sensor 992 is installed in the sealing top cover 3 and electrically connected to the controller 98, and is used to detect whether the mouthpiece cover 200 is covered on the mouthpiece 1. The first fan 993 is located in the first cavity 201 and electrically connected to the controller 98 and the battery 97, and is used to drive the airflow to move towards the air inlet groove 36 when the mouthpiece cover 200 starts to move away from the mouthpiece 1. Thus, the aerosol remaining in the mouthpiece 1 is not easy to flow into the airflow sensor 6. The second fan 994 is located in the second cavity 202 and electrically connected to the controller 98 and the battery 97, and is used to drive the airflow to move towards the second atomization assembly 5 when the second atomization assembly 5 works, so as to blow the aerosol generated by the second atomization assembly 5 out of the present application.

[0056] In the present embodiment, the second fan 994 is located at the bottom of the second cavity 202, and the second fan 994 is communicated to the second atomization assembly 5 through the first atomization assembly 4. Therefore, when the user does not smoke, the second fan 994 blows the aerosol generated by the first atomization assembly 4 and the aerosol generated by the second atomization assembly 5 to the outside of the present application, reducing the probability of condensation of the aerosol in the present application.

[0057] Please refer to Figure 7 An aerosol generating device control method suitable for the aerosol generating device described above, comprising the following steps:

[0058] S1, obtaining a smoking start signal transmitted by the airflow sensor 6;

[0059] After the user covers the mouthpiece cover 200 on the mouthpiece 1, the user can start smoking. When smoking, the airflow at the air outlet groove 32 flows towards the air outlet hole 11, thereby forming a negative pressure, which can trigger the airflow sensor 6. The airflow sensor 6 sends a smoking start signal to the controller 98. The smoking start signal can be a high-level signal.

[0060] S2, controlling the first atomization assembly 4 to heat and atomize the aerosol generating liquid according to the smoking start signal;

[0061] After receiving the smoking start signal, the controller 98 controls the battery 97 to supply power to the first atomization assembly 4 to atomize the aerosol generating liquid.

[0062] S3, obtaining a smoking end signal transmitted by the airflow sensor 6;

[0063] When the user does not smoke, the air pressure at the air outlet groove 32 is equal to the air pressure at the air inlet groove 36, and the airflow sensor 6 sends an end-of-smoking signal to the controller 98. The end-of-smoking signal can be a low-level signal.

[0064] S4. According to the end-of-smoking signal, the residual amount of the condensed liquid at the second atomization assembly 5 is determined.

[0065] After each puff of the aerosol is smoked, the controller 98 determines the residual amount of the condensed liquid at the second atomization assembly 5 according to the capacitance of the capacitor 96.

[0066] S5. When the residual amount of the condensed liquid at the second atomization assembly 5 is greater than a preset value, the second atomization assembly 5 is controlled to heat to atomize the condensed liquid, and the second fan 994 is controlled to drive away the aerosol formed by the atomization of the condensed liquid.

[0067] That is, when the residual amount of the condensed liquid is large enough to prevent the second liquid absorbing cotton column 51 from drying out when the second heating element 52 is working, the second atomization assembly 5 can be controlled to heat to atomize the condensed liquid, thereby preventing the condensed liquid from being oversaturated and thus being inhaled by the user. In addition, by controlling the second fan 994 to drive away the aerosol formed by the atomization of the condensed liquid, the aerosol can be better prevented from being re-condensed in the mouthpiece 1. It should be understood that the residual amount can be set according to the size of the volume of the second atomization assembly 5, and the specific value is not limited herein.

[0068] Preferably, in the control method, before the step S4, the following step is further included:

[0069] According to the end-of-smoking signal, the first fan 993 is controlled to drive the airflow towards the air inlet groove 36.

[0070] That is, after each puff of the aerosol is smoked, the first fan 993 is used to blow the gas in the air outlet groove 32 towards the air outlet hole, thereby better preventing the residual aerosol from flowing and forming condensed liquid in the present application.

[0071] Preferably, in the control method, after the step S5, the following step is further included:

[0072] The number of puffs of the user is counted, and when the number of puffs is greater than a preset number and the cumulative amount of the condensed liquid at the second atomization assembly 5 is less than the preset value, a condensed liquid leakage alarm signal is sent.

[0073] Because of smoking, there must be condensation, and with the increase of the number of smoking, the condensate must increase. Assuming that the preset number is 200 times, if the cumulative amount of condensate after 200 times of smoking is still less than the preset value, it means that the second atomization assembly 5 is not assembled in place, and the condensate in the mist outlet hole 11 has leaked to other areas, and the controller 98 sends a condensate leakage alarm signal, thus protecting the user's health well.

[0074] Preferably, in the control method, the step S2 specifically comprises:

[0075] According to the smoking start signal, it is detected whether the suction nozzle cover 200 is covered at the suction nozzle 1. When it is detected that the suction nozzle cover 200 is not covered at the suction nozzle 1, the first atomization assembly 4 is prohibited from heating and a sealing failure signal is sent, otherwise, the first atomization assembly 4 is controlled to heat to atomize the aerosol generating liquid.

[0076] After the controller 98 obtains the smoking start signal transmitted by the airflow sensor 6, it is detected by the Hall sensor 992 whether the suction nozzle cover 200 is covered at the suction nozzle 1. When it is detected that the suction nozzle cover 200 is not covered at the suction nozzle 1, it means that the air path blocking assembly 7 has failed, and the controller 98 sends a sealing failure signal. This method not only can simply and efficiently detect the sealing property of the air path blocking assembly 7, but also protects the airflow sensor 6 well. It can be understood that the controller 98 can include a single-chip microcomputer, a loudspeaker and a light alarm electrically connected with the single-chip microcomputer, the loudspeaker is used to send a condensate leakage alarm signal, and the light alarm is used to send a sealing failure signal.

[0077] In summary, first, in the first state, the suction nozzle cover 200 is separated from the suction nozzle 1, and the air path blocking assembly 7 is closed by the elastic restoring member 8, the airflow sensor 6 is in a sealed space, thus avoiding the condensate flowing into the airflow sensor 6, thereby improving the service life, and in the transportation process, the airflow sensor 6 will not be triggered by the external negative pressure of the application; second, when smoking is needed, the suction nozzle cover 200 is covered at the suction nozzle 1, the suction nozzle cover 200 automatically drives the air path blocking assembly 7 to open the air outlet groove 32, and the liquid plug 2001 pushes the condensate in the mist outlet hole 11 to flow towards the second atomization assembly 5, so that the user will not smoke the condensate at the suction nozzle 1 during smoking, and when smoking is finished, the second atomization assembly 5 can atomize the accumulated condensate, avoiding too much condensate, thus protecting the airflow sensor 6 better.
