Description

Technical Field

[0001] The present invention relates to the technical field of aerosol generation, and in particular to an aerosol generating device. Background Art

[0002] Currently, aerosol generating devices include an atomizer and a main unit. The atomizer's housing houses a liquid reservoir and an atomizer core, which is directly connected to the liquid in the reservoir. The main unit houses a battery. The atomizer is mounted on the main unit, electrically connecting the atomizer core to the battery. The atomizer core heats and atomizes the liquid in the reservoir, generating an aerosol.

[0003] The atomizer core has a liquid inlet that is directly connected to the liquid storage chamber, making it impossible to automatically control the connection between the liquid storage chamber and the atomizer core according to the use of the atomizer core. In addition, when the atomizer core needs to be replaced, the liquid in the liquid storage chamber must be emptied first, otherwise the liquid in the liquid storage chamber will spill, which will not provide a good user experience. Summary of the Invention

[0004] Based on this, it is necessary to provide an aerosol generating device in which the atomizer core and the liquid storage chamber are separately arranged without affecting each other, and the atomizer core and the liquid storage chamber are automatically connected or the liquid inlet is closed to solve the problem of how to meet the requirements ...

[0005] An aerosol generating device comprising:

[0006] The main unit is provided with a first mounting port and a second mounting port;

[0007] a liquid storage unit, provided on the first mounting port, and capable of storing liquid inside the liquid storage device;

[0008] an elastic sealing member movably disposed on the liquid storage unit, wherein the elastic sealing member is hollow inside and has a liquid inlet on the outside thereof communicating with the inside; when the elastic sealing member is in a reset state, the liquid inlet is sealed by the liquid storage unit;

[0009] an atomizing core assembly, disposed on the second mounting port, for atomizing liquid; and

[0010] An elastic opening member is movably provided on the atomizer core assembly. The elastic opening member is hollow inside and has openings at both ends. The elastic opening member can lift the elastic sealing member to connect the liquid inlet with the liquid in the liquid storage unit. The openings at both ends of the elastic opening member are respectively connected with the interior of the elastic sealing member and the interior of the atomizer core assembly.

[0011] In the above-mentioned aerosol generating device, the liquid storage unit and the atomizer core assembly are both independently provided on the main unit. In one embodiment, the liquid storage unit is first installed on the first mounting port of the main unit, and then the atomizer core assembly is installed on the second mounting port of the main unit. At this time, the elastic opening member will lift the elastic seal, exposing the liquid inlet to the liquid storage unit. In addition, the liquid in the liquid storage unit can flow into the elastic seal through the liquid inlet, and then the liquid flows into the atomizer core assembly through the elastic seal and the elastic opening member to be atomized to form an aerosol. When the atomizer core assembly is removed from the second mounting port of the main unit, the elastic opening member separates from the elastic seal, causing the elastic seal to return to its original position, and the liquid inlet is hidden in the liquid storage unit, thereby preventing the liquid in the liquid storage unit from flowing out, effectively preventing liquid leakage when the atomizer core assembly is removed. The atomizer core assembly and the liquid storage unit are provided separately, do not affect each other, and meet the requirements of automatically opening or closing the liquid inlet of the atomizer core assembly and the liquid storage unit.

[0012] In one embodiment, a sealing member is further included. The sealing member is disposed within the liquid storage unit, and the elastic sealing member passes through the sealing member. In a normal state, the liquid inlet is concealed within the sealing member. When abutted by the elastic opening member, the elastic sealing member moves into the liquid storage unit and separates the liquid inlet from the sealing member. The provision of the sealing member facilitates the concealment and exposure of the liquid inlet.

[0013] In one embodiment, the elastic sealing member includes a sealing cover and a first elastic component. The first elastic component is movably mounted on the liquid storage unit and communicates with the elastic opening member. The first elastic component is provided with the liquid inlet, and the sealing cover is mounted on the first elastic component. In a normal state, the sealing cover abuts the blocking member, concealing the liquid inlet. When the elastic opening member abuts, the first elastic component drives the sealing cover and the blocking member apart, allowing the liquid inlet to communicate with the interior of the liquid storage unit. In a normal state, under the elastic force of the first elastic component, the sealing cover presses against the blocking member. The sealing cover and the blocking member cooperate to seal the liquid inlet, effectively preventing the liquid in the liquid storage unit from flowing out. When the first elastic component is pressed by the elastic opening member, the sealing cover separates from the blocking member, allowing the liquid inlet to communicate with the liquid in the liquid storage unit. When the atomizer core assembly is disassembled, the pressure of the elastic opening member is released. Under the elastic restoring force of the first elastic component, the sealing cover returns to its original position and once again cooperates with the blocking member to seal the liquid inlet.

[0014] In one embodiment, the first elastic component includes a first elastic component and a sealing body, the liquid storage unit is provided with a movable cavity, the first elastic component is sleeved on the sealing body and abuts against the cavity wall of the movable cavity, so that the sealing body can move closer to or away from the interior of the liquid storage unit, the interior of the sealing body is hollow and connected to the elastic opening member, the liquid inlet is provided on the sealing body, and the sealing cover is provided on the top of the sealing body.

[0015] In one embodiment, a first mating portion is provided on the second mounting port, and a second mating portion is provided on the elastic opening member. When the atomizer core assembly is installed into the second mounting port, the second mating portion slides with the first mating portion, so that the elastic opening member is pressed into the atomizer core assembly after being installed into the second mounting port. The elastic opening member and the elastic sealing member are aligned in position and then the elastic sealing member is lifted up. This allows the elastic opening member to be pressed into the atomizer core assembly more smoothly when the atomizer core assembly is installed. Moreover, when the atomizer core assembly is disassembled, the atomizer core assembly only needs to be moved a few millimeters outward from the main unit to disengage the elastic opening member from the elastic sealing member. The elastic sealing member can then quickly return to its original position and seal the liquid inlet in a timely manner.

[0016] In one embodiment, the first matching portion is a first inclined surface provided on the outer opening end of the second mounting port, and the second matching portion is a second inclined surface provided on the outer periphery of the top end of the elastic opening member.

[0017] In one embodiment, the elastic opening member includes a driving member and a second elastic member that pass through the upper and lower parts. The atomization core assembly is provided with an installation cavity and an atomization cavity. The installation cavity is communicated with the atomization cavity. The second elastic member is arranged in the installation cavity. The driving member abuts against the second elastic member. The driving member can move into the installation cavity to compress the second elastic member. Under the action of the elastic restoring force of the second elastic member, the driving member moves away from the installation cavity and lifts the elastic sealing member.

[0018] In one embodiment, a third mating portion is provided on the end of the driving member away from the mounting cavity, and a fourth mating portion is provided on the elastic sealing member. The third mating portion and the fourth mating portion are slidably engaged with each other to enable the driving member to lift the elastic sealing member or to stagger and separate the driving member from the elastic sealing member. This allows the driving member to lift the elastic sealing member more smoothly, and when the atomizer core assembly is disassembled, the driving member can be separated from the elastic sealing member more quickly and smoothly.

[0019] In one embodiment, the third matching portion is a third inclined surface provided on the outer periphery of the top end of the driving member, and the fourth matching portion is a fourth inclined surface provided on the outer periphery of the bottom end of the elastic sealing member.

[0020] In one embodiment, at least one of the following technical solutions is included:

[0021] The driving member includes a fixing cap and a top cap provided on the fixing cap, the top cap and the fixing cap are connected vertically, the fixing cap abuts against the cavity wall of the mounting cavity and the second elastic component respectively, the fixing cap is in communication with the atomizing cavity, and the top cap can be in communication with the elastic sealing member;

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0043] See also Figure 1 and Figure 2 In one embodiment, an aerosol generating device 100 includes: a main unit 1, a liquid storage unit 2, an elastic seal 3, an atomizing core assembly 4, and an elastic opening member 5. The main unit 1 is provided with a first mounting port 11 and a second mounting port 12. The liquid storage unit 2 is provided on the first mounting port 11 and is capable of storing liquid therein. The atomizing core assembly 4 is provided on the second mounting port 12 and is used to atomize liquid. The elastic seal 3 is movably provided on the liquid storage unit 2. The elastic seal 3 is hollow inside and has a liquid inlet 31 on the outside that communicates with the interior. When the elastic seal 3 is in the reset state, the liquid inlet 31 is sealed by the liquid storage unit 2. The elastic opening member 5 is movably provided on the atomizing core assembly 4. The elastic opening member 5 is hollow inside and has openings at both ends. The elastic opening member 5 can lift the elastic seal 3 to connect the liquid inlet 31 with the liquid in the liquid storage unit 2. The openings at both ends of the elastic opening member 5 communicate with the interior of the elastic seal 3 and the interior of the atomizing core assembly 4, respectively.

[0044] In the aerosol generating device 100, the liquid storage unit 2 and the atomizing core assembly 4 are independently provided on the main unit 1. In one embodiment, please refer to Figure 3 and Figure 4 , first install the liquid storage unit 2 on the first installation port 11 of the host 1, please refer to Figure 5 and Figure 6, then the atomizer core assembly 4 is installed on the second mounting port 12 of the main unit 1. At this time, the elastic opening member 5 will lift the elastic seal 3, exposing the liquid inlet 31 to the liquid storage unit 2, and the liquid in the liquid storage unit 2 can flow into the elastic seal 3 through the liquid inlet 31, and then the liquid flows into the atomizer core assembly 4 through the elastic seal 3 and the elastic opening member 5 to be atomized and form an aerosol. When the atomizer core assembly 4 is removed from the second mounting port 12 of the main unit 1, the elastic opening member 5 separates from the elastic seal 3, causing the elastic seal 3 to return to its original position, and the liquid inlet 31 is closed in the liquid storage unit 2, thereby preventing the liquid in the liquid storage unit 2 from flowing out, effectively preventing liquid leakage when the atomizer core assembly 4 is removed. The atomizer core assembly 4 and the liquid storage unit 2 are set separately and do not affect each other, and meet the automatic connection or closing of the liquid inlet 31 between the atomizer core assembly 4 and the liquid storage unit 2.

[0045] See also Figure 3 In one embodiment, a first mounting opening 11 is defined at the top of the main unit 1, and a second mounting opening 12 is defined on the outer circumference of the main unit 1. Specifically, the liquid storage unit 2 is mounted at the top of the main unit 1, and the atomizer core assembly 4 is inserted into the main unit 1 from the outer circumference of the main unit 1. The liquid storage unit 2 is located above the atomizer core assembly 4. A cavity 16 is defined within the main unit 1 for accommodating the atomizer core assembly 4. The top of the cavity 16 communicates with the first mounting opening 11, and the cavity 16 communicates with the second mounting opening 12 along the transverse direction of the main unit 1. An airway hole 111 is defined in the center of the first mounting opening 11, as well as a liquid passage opening 112 located to one side of the airway hole 111. Liquid inlet seals 17 are located on both sides of the liquid passage opening 112 to prevent leakage. When the liquid storage unit 2 and the atomizer core assembly 4 are installed on the main unit 1, the airway hole 111 is connected to the interior of the liquid storage unit 2 and the atomizer core assembly 4 respectively. The top of the elastic opening member 5 enters the liquid channel opening 112 and lifts the elastic sealing member 3. The liquid channel opening 112 is connected to the elastic opening member 5 and the elastic sealing member 3 respectively.

[0046] See also Figure 2 To facilitate the concealment and exposure of the liquid inlet 31, a sealing member 6 is provided within the liquid storage unit 2, through which the elastic seal 3 passes. When the atomizer core assembly 4 is not installed, the liquid inlet 31 is concealed within the sealing member 6. After the atomizer core assembly 4 is installed, the elastic opening member 5 lifts the elastic seal 3, causing it to move into the liquid storage unit 2 and separate the liquid inlet 31 from the sealing member 6, allowing the liquid in the liquid storage unit 2 to flow out and be atomized. After the atomizer core assembly 4 is removed, the elastic seal 3 moves back out of the liquid storage unit 2, and the liquid inlet 31 is once again concealed within the sealing member 6.

[0047] See also Figure 7In one embodiment of the elastic sealing member 3, the elastic sealing member 3 includes a sealing cover 32 and a first elastic component 33. The first elastic component 33 is movably mounted on the liquid storage unit 2. A liquid outlet 333 is provided at one end of the first elastic component 33, which communicates with the liquid inlet 31. The first elastic component 33 communicates with the elastic opening member 5 through the liquid outlet 333. The liquid inlet 31 is provided on the sidewall of the first elastic component 33, and the sealing cover 32 is mounted on the end of the first elastic component 33. In a normal state, the sealing cover 32 abuts the blocking member 6, concealing the liquid inlet 31. Under the abutment of the elastic opening member 5, the first elastic component 33 drives the sealing cover 32 to separate from the blocking member 6, thereby establishing liquid communication between the liquid inlet 31 and the interior of the liquid storage unit 2. The blocking member 6 may be made of sealing silicone.

[0048] It is understood that under normal conditions, under the elastic force of the first elastic component 33, the sealing cover 32 presses against the blocking member 6. The sealing cover 32 and the blocking member 6 cooperate to seal the liquid inlet 31, effectively preventing the liquid in the liquid storage unit 2 from flowing out. When the first elastic component 33 is pressed by the elastic opening member 5, the sealing cover 32 separates from the blocking member 6, allowing the liquid inlet 31 to communicate with the liquid in the liquid storage unit 2. When the atomizer core assembly 4 is disassembled, the pressing force of the elastic opening member 5 is removed. Under the elastic restoring force of the first elastic component 33, the sealing cover 32 returns to its original position and cooperates with the blocking member 6 again to seal the liquid inlet 31.

[0049] Furthermore, the first elastic component 33 includes a first elastic component 331 and a sealing body 332. The liquid storage unit 2 is provided with a movable cavity 21. The first elastic component 331 is sleeved on the sealing body 332. The first elastic component 331 is always in a compressed state and abuts against the cavity wall of the movable cavity 21, allowing the sealing body 332 to move closer to or away from the interior of the liquid storage unit 2. When the sealing body 332 is lifted up, the first elastic component 331 is compressed more severely. The sealing body 332 is hollow inside, and the bottom end of the sealing body 332 is connected to the elastic opening member 5. A liquid inlet 31 is provided on the circumferential outer side of the top of the sealing body 332, and a sealing cover 32 is provided on the top of the sealing body 332. The first elastic component 331 can specifically be a spring, and the sealing body 332 is a metal tube.

[0050] The sealing body 332 may include a truncated cone end with a larger diameter and a cylindrical end with a smaller diameter. The bottom end of the cylindrical end is connected to the truncated cone end, and the cylindrical end is connected to the middle of the truncated cone end. The first elastic component 331 is sleeved on the cylindrical end, and the two ends of the first elastic component 331 are respectively in contact with the truncated cone end and the cavity wall of the movable cavity 21. The liquid inlet 31 is provided on the outer side of the top end of the cylindrical end. The sealing cover 32 is sleeved on the top end of the cylindrical end. A step is provided on the bottom end of the sealing cover 32, and the sealing cover 32 is in contact with the sealing member 6 through the step to seal the liquid inlet 31. Of course, the sealing cover 32 may also not be provided with a step, and may be sealed by sliding down as a whole into the opening of the sealing member 6 to achieve the sealing of the liquid inlet 31.

[0051] See also Figure 8 and Figure 9 In another embodiment, the second mounting opening 12 is provided with a first mating portion 121, and the elastic opening member 5 is provided with a second mating portion 51. When the atomizer core assembly 4 is installed into the second mounting opening 12, the second mating portion 51 slides with the first mating portion 121, causing the elastic opening member 5 to be pressed into the atomizer core assembly 4 after being installed into the second mounting opening 12. The elastic opening member 5 then aligns with the elastic seal 3, lifting the elastic seal 3. This allows the elastic opening member 5 to be pressed more smoothly into the atomizer core assembly 4 when the atomizer core assembly 4 is installed. A chamfer 1121 is provided on the bottom sidewall of the liquid passage opening 112. When removing the atomizer core assembly 4, the second mating portion 51 of the elastic opening member 5 slides with the chamfer 1121. Simply moving the atomizer core assembly 4 a few millimeters outward from the main unit 1 disengages the elastic opening member 5 from the elastic seal 3, allowing the elastic seal 3 to quickly return to its original position, promptly sealing the liquid inlet 31.

[0052] See also Figure 5 Based on the above embodiment, the first matching portion 121 is a first inclined surface provided on the outer opening end of the second mounting port 12, and the second matching portion 51 is a second inclined surface provided on the outer periphery of the top end of the elastic opening member 5.

[0053] See also Figure 8 In one embodiment of the elastic opening member 5, the elastic opening member 5 includes a driving member 52 and a second elastic member 53 that extend vertically. The atomizer core assembly 4 is provided with a mounting chamber 41 and an atomizing chamber 42, and the mounting chamber 41 is connected to the atomizing chamber 42. The second elastic member 53 is disposed in the mounting chamber 41, and the driving member 52 abuts against the second elastic member 53. The driving member 52 can move into the mounting chamber 41 to compress the second elastic member 53. Under the action of the elastic restoring force of the second elastic member 53, the driving member 52 moves away from the mounting chamber 41 and lifts the sealing body 332. The second elastic member 53 can specifically be a spring.

[0054] In some embodiments, the driving member 52 includes a fixed cap 521 and a top cap 522 provided on the fixed cap 521. The top cap 522 and the fixed cap 521 are connected from top to bottom. The fixed cap 521 is respectively in contact with the cavity wall of the mounting cavity 41 and the second elastic component 53. The fixed cap 521 is in communication with the atomizing cavity 42, and the top cap 522 can be in communication with the sealing body 332. Specifically, the cavity wall of the mounting cavity 41 extends toward the middle to form a limiting portion 411. The opposite ends of the fixed cap 521 are respectively in contact with the limiting portion 411 and the second elastic component 53, which can drive the top cap 522 to extend or be retracted into the atomizing core assembly 4. There is a spacing space 43 between the top of the limiting portion 411 and the top surface of the atomizing core assembly 4. When the fixed cap 521 drives the top cap 522 to be retracted into the atomizing core assembly 4, the top cap 522 is stored in the spacing space 43.

[0055] It is understood that in order for the top cap 522 to lift the sealing body 332, the elastic force of the second elastic component 53 must be greater than the elastic force of the first elastic component 331. Under the elastic force of the second elastic component 53, the top cap 522 can overcome the elastic force of the first elastic component 331 and compress the first elastic component 331, thereby lifting the sealing body 332.

[0056] See also Figure 10 In other embodiments, a third mating portion 5221 is provided at the top of the top cap 522, and a fourth mating portion 3321 is provided at the bottom of the sealing body 332. The third mating portion 5221 and the fourth mating portion 3321 slide together to allow the top cap 522 to lift the sealing body 332, or to stagger and separate the top cap 522 from the sealing body 332. This allows the top cap 522 to lift the sealing body 332 more smoothly, and when the atomizer core assembly 4 is disassembled, the top cap 522 can be separated from the sealing body 332 more quickly and smoothly, allowing the sealing body 332 to return to its original position more quickly, sealing the liquid inlet 31. The third mating portion 5221 is a third inclined surface provided on the outer periphery of the top end of the top cap 522, and the fourth mating portion 3321 is a fourth inclined surface provided on the outer periphery of the bottom end of the sealing body 332.

[0057] See also Figure 2 The atomizer core assembly 4 includes a bracket 44 and an atomizer core 45. A second liquid storage chamber 46 is provided within the bracket 44 and communicates with the drive member 52. The atomizer core 45 is disposed within the second liquid storage chamber 46 and has an atomizer chamber 42 therein. Liquid within the liquid storage unit 2 can flow into the second liquid storage chamber 46 through the liquid inlet 31, the sealing body 332, the top cap 522, the fixing cap 521, and the mounting chamber 41, and is then heated and atomized by the atomizer core 45.

[0058] See also Figure 8 and Figure 11An air intake channel 22 is provided in the liquid storage unit 2 , and an air intake channel 7 communicating with the outside is formed between the bracket 44 and the second mounting port 12 , or an air intake channel 7 communicating with the outside is provided on the bracket 44 .

[0059] The atomizing chamber 42 is respectively connected to the air inlet channel 22 and the air inlet channel 7. After the external air enters the atomizing chamber 42 through the air inlet channel 7, the aerosol generated by atomization is taken out through the air inlet channel 22 and is inhaled by the user.

[0060] See also Figure 11 and Figure 12 A long ridge 122 extends inward from the outer end surface of the second mounting opening 12. A long groove 441 is provided on the outer side of the bracket 44, communicating with the atomizing chamber 42. When the atomizing core assembly 4 is installed in the main unit 1, the long groove 441 slides along the long ridge 122. The air inlet channel 7 can be formed directly within the long ridge 122 or between the long ridge 122 and the long groove 441.

[0061] See also Figure 8 It should be noted that in order to ensure that when the liquid flows into the second liquid storage chamber 46, there will be no leakage at other positions, a second sealing silicone 47 is provided on the top of the bracket 44. The second sealing silicone 47 is sealed with the top of the atomizer core 45 and the outer side of the top cap 522.

[0062] See also Figure 9 In other embodiments, the host 1 further includes a battery 13, a PCB control board 14, and a spring electrode 15. The spring electrode 15 is protruding from the inner bottom wall of the second mounting opening 12, and the spring electrode 15 is electrically connected to the battery 13.

[0063] See also Figure 5 An electrode 48 electrically connected to the atomizer core 45 is provided at the bottom of the bracket 44 of the atomizer core assembly 4. When the bracket 44 slides laterally into the second mounting opening 12, the electrode 48 elastically abuts the spring-loaded electrode 15, forming an electrical connection. The PCB control board 14 is electrically connected to the atomizer core 45 and the battery 13. The PCB control board 14 controls the atomization operation of the atomizer core 45, including but not limited to starting and stopping atomization, atomization power, and atomization duration.

[0064] See also Figure 12 In some embodiments, the electrode 48 includes a positive electrode and a negative electrode, and the spring-loaded electrode 15 includes a positive spring-loaded electrode and a negative spring-loaded electrode.
