[0033] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0034] Please refer to Figure 1 and Figure 2, this application provides an aerosol generating device 100, which includes a housing assembly 10, an atomization core 20 and a shielding member 30. The housing assembly 10 includes a mouthpiece 11 and a liquid storage cavity 12 disposed inside the housing assembly 10. The liquid storage cavity 12 is used to store a liquid matrix. The liquid storage cavity 12 is in liquid conduction connection with the atomization core 20 to provide the liquid matrix for the atomization core 20 to generate aerosol. There is a main airway 71 between the atomization core 20 and the mouthpiece 11, and the main airway 71 is used to direct the aerosol generated by the atomization core 20 to the mouthpiece 11 for the user to inhale. The shielding member 30 is connected to the mouthpiece 11, and the mouthpiece 11 is configured to communicate with the outside of the aerosol generating device 100 and the main airway 71 when the shielding member 30 is removed or when the shielding member 30 is broken. Among them, the liquid storage cavity 12 and the main airway 71 are in gas conduction connection to balance the air pressure between the main airway 71 and the liquid storage cavity 12.
[0035] In the aerosol generating device of this application, the shielding member 30 is connected to the mouthpiece 11 to shield the air flow between the outside and the main airway 71, which is convenient for the airtight storage and transportation of the aerosol generating device, helps to prevent the liquid matrix from volatilizing, being oxidized and deteriorating, and can also prevent external foreign matters such as dust from falling into the main airway 71 to contaminate the main airway 71. It can also reduce the influence of the air pressure change in the storage environment on the internal air pressure of the aerosol generating device. By setting the liquid storage cavity 12 and the main airway 71 to be in gas conduction connection, the liquid storage cavity 12 and the main airway 71 maintain air pressure balance during the airtight storage and transportation of the aerosol generating device, so as to prevent the liquid matrix from leaking due to the air pressure change in the liquid storage cavity 12 caused by the change of air pressure and / or temperature in the environment during the airtight storage and transportation of the aerosol generating device.
[0036] In some embodiments, please refer to Figure 1 and Figure 2 , an end of the liquid storage cavity 12 is provided with a first opening 121. There is a first sealing member 40 between the mouthpiece 11 and the liquid storage cavity 12. The first sealing member 40 is disposed at the first opening 121 to block the first opening 121, and the first sealing member 40 is hermetically connected to the housing assembly 10, thereby preventing the liquid matrix in the liquid storage cavity 12 from leaking to the mouthpiece 11. The liquid storage cavity 12 and the main airway 71 can be in gas conduction connection through an auxiliary channel 41.
[0037] Please refer to Figure 3 and Figure 4 , as an embodiment, the first sealing member 40 is provided with a through hole 411, and the through hole 411 constitutes at least a part of the auxiliary channel 41. Please refer to Figure 4, the diameter D2 of the through hole 411 satisfies: 0.1 mm ≤ D2 ≤ 1.5 mm. For example, D2 can be 0.1 mm, 0.2 mm, 0.5 mm, 0.7 mm, 0.9 mm, 1.1 mm, 1.3 mm, 1.5 mm. By controlling the diameter of the through hole 411 within the above range, the through hole 411 can not only conduct air to connect the liquid storage cavity 12 and the main air duct 71 when the air pressure in the liquid storage cavity 12 reaches the preset value, but also ensure that the liquid storage cavity 12 has good sealing performance when the air pressures in the liquid storage cavity 12 and the main air duct 71 are roughly balanced, preventing the liquid matrix in the liquid storage cavity 12 from leaking through the through hole 411 and preventing the fluid in the main air duct 71 from easily entering the liquid storage cavity 12 through the through hole 411. Of course, during the use of the aerosol generating device, if the air pressure in the liquid storage cavity 12 is too low, resulting in a decrease in the flow rate of the liquid matrix into the atomization core 20, the gas in the main air duct 71 can flow reversely into the liquid storage cavity 12 through the through hole 411, making the air pressures in the liquid storage cavity 12 and the main air duct 71 roughly balanced and preventing the atomization core 20 from dry burning.
[0038] Specifically, when the diameter of the through hole 411 is less than 0.1 mm, the air conduction flux of the through hole 411 is small. If the air pressure change in the liquid storage cavity 12 is relatively drastic, it will cause the liquid storage cavity 12 and the main air duct 71 to not reach air pressure balance in time, easily resulting in the leakage of the liquid matrix in the liquid storage cavity 12 or easily causing the atomization core 20 to dry burn. When the diameter of the through hole 411 is greater than 1.5 mm, the sealing performance of the liquid storage cavity 12 will be damaged, and the liquid matrix in the liquid storage cavity 12 can easily leak through the through hole 411.
[0039] It should be noted that the diameter D2 of the above through hole 411 refers to the minimum distance between the two opposite inner walls of the through hole. For example, if the through hole 411 includes a circular hole, the diameter D2 of the through hole 411 of the circular hole is basically the inner diameter of the circular hole; for example, if the through hole 411 includes a strip-shaped hole, the diameter D2 of the through hole 411 of the strip-shaped hole is basically the length of the short side of the strip-shaped hole. The present application does not limit the hole shape of the through hole 411.
[0040] Among them, the through hole 411 can extend linearly in the first seal 40 or can extend in a bent shape in the first seal 40. The present application does not limit the extension shape of the through hole 411 in the first seal 40.
[0041] In order to prevent the liquid matrix in the liquid storage cavity 12 from leaking through the through hole 411 in some cases, a fiber absorption element 50 can be provided between the mouthpiece 11 and the first seal 40. The fiber absorption element 50 can absorb the liquid matrix leaking through the through hole 411, preventing the leaked liquid matrix from being inhaled into the user's mouth and preventing the leaked liquid matrix from being discharged outside the aerosol generating device.
[0042] In one embodiment, there is a first gap 412 between the first seal 40 and the fibrous absorbent element 50. The first gap 412 communicates with the main airway 71, and the through-hole 411 communicates the first gap 412 and the liquid storage chamber 12. In this way, the first gap 412 is a component of the auxiliary channel 41, and the gas in the liquid storage chamber 12 can enter the main airway 71 through the through-hole 411 and the first gap 412 in sequence to balance the air pressure in the liquid storage chamber 12 and the air pressure in the main airway 71.
[0043] The fibrous absorbent element 50 may be provided with a through-hole 51, and the through-hole 51 is a component of the main airway 71, that is, the inner wall of the through-hole 51 defines a partial boundary of the main airway 71. The aerosol generated at the atomization core 20 flows through the through-hole 51 to the mouthpiece 11. Therefore, the fibrous absorbent element 50 can also absorb at least part of the condensate formed in the main airway 71 due to aerosol condensation.
[0044] In some embodiments, refer to Figure 3 , the first seal 40 has a first surface 42, the first surface 42 defines a partial boundary of the first gap 412, and an annular boss 43 is provided on the first surface 42. The inner wall of the annular boss 43 defines a partial boundary of the main airway 71. The annular boss 43 can hold the liquid matrix that leaks to the first gap 412 through the through-hole 411 and is not absorbed by the fibrous absorbent element 50 in time in the first gap 412, and can prevent the liquid matrix from leaking into the main airway 71.
[0045] Wherein, there is a second gap 44 between the annular boss 43 and the fibrous absorbent element 50. The first gap 412 communicates with the main airway 71 through the second gap 44. Thus, the second gap 44 is a component of the auxiliary channel 41, so that the gas in the liquid storage chamber 12 can enter the first gap 412 from the through-hole 411 and then enter the main airway 71 through the second gap 44.
[0046] The fiber absorption element 50 includes fibers with minute gaps between adjacent fibers, such that there are a number of minute pores in the fiber absorption element 50. The fiber absorption element 50 absorbs liquid through these pores. In fact, part of the gas discharged from the liquid storage cavity 12 through the through-hole 411 can also enter the pores of the fiber absorption element 50 and then enter the air guide hole 51 through the pores in the fiber absorption element 50. However, the pores on the fiber absorption element 50 have a small diameter and a very small air conduction flux. Although gas can flow between the through-hole 411 and the air guide hole 51 through these pores, when the air pressure in the liquid storage cavity 12 changes violently, there will still be a situation where the air pressure balance between the liquid storage cavity 12 and the main air passage 71 cannot be achieved in time, resulting in leakage of the liquid matrix in the liquid storage cavity 12 or dry burning of the atomization core 20. To overcome this problem, in this embodiment, a second gap 44 is provided between the first seal 40 and the fiber absorption element 50 to directly connect the first gap 412 and the main air passage 71. The minimum distance D1 between the second gap 44 and the first surface 41 is significantly greater than the gap between adjacent fibers in the fiber absorption element 50, and the air conduction flux of the second gap 44 is significantly greater than the air conduction flux of the pores on the fiber absorption element 50.
[0047] Moreover, after the fiber absorption element 50 absorbs liquid, at least part of the pores in the fiber absorption element 50 will be blocked by the liquid, making it difficult for gas to flow through the fiber absorption element 50, which is not conducive to the air conduction connection between the through-hole 411 and the main air passage 71. In this embodiment, providing a second gap 44 between the first seal 40 and the fiber absorption element 50 can perfectly overcome this problem.
[0048] In some embodiments, please refer to Figure 4 and Figure 5 , the depth D3 of the second gap 44 satisfies: 0.1 mm ≤ D3 ≤ 1.5 mm. For example, D3 can be 0.1 mm, 0.2 mm, 0.5 mm, 0.7 mm, 0.9 mm, 1.1 mm, 1.3 mm, 1.5 mm. By controlling the depth D3 of the second gap 44 within the above range, it can ensure that when the air pressure between the liquid storage cavity 12 and the main air passage 71 is unbalanced, the air flow between the first gap 412 and the main air passage 71 is smooth, without damaging the sealing of the liquid storage cavity 12, and also helps to prevent the liquid matrix from leaking into the main air passage 71.
[0049] As an embodiment, please refer to Figure 4, the annular boss 43 is in abutting connection with the bottom of the fiber absorption element 50, and the annular boss 43 supports the fiber absorption element 50, that is, the annular boss 43 holds up the fiber absorption element 50 relative to the first surface 42, so that a first gap 412 is formed between the first seal 40 and the fiber absorption element 50. A notch 431 is provided on the annular boss 43, and the notch 431 penetrates through the side wall of the annular boss 43. The notch 431 constitutes a second gap 44 between the annular boss 43 and the fiber absorption element 50. That is, the gas in the first gap 412 can enter the main air duct 71 through the notch 431. The notch 431 constitutes the second gap 44. The depression depth of the notch 431 can be D3.
[0050] The notch 431 is spaced from the first surface 42 to form a step between the notch 431 and the first surface 42, so as to prevent the liquid that is not absorbed by the fiber absorption element 50 in time in the first gap 412 from flowing through the notch 431 into the main air duct 71. Wherein, the height of the step or the minimum distance D1 between the boundary of the second gap 44 and the first surface 42 satisfies: 0.5 mm ≤ D1 ≤ 3.5 mm. For example, D1 can be 0.8 mm. Since at least part of the first gap 412 is arranged between the first seal 40 and the fiber absorption element 50, and the fiber absorption element 50 is used to absorb at least part of the liquid matrix leaking through the through hole 411, D1 should not be too large, otherwise it will affect the absorption of the liquid matrix in the first gap 412 by the fiber absorption element 50, but D1 should not be too small either. If the fiber absorption element 50 is too close to the first surface 42, the fiber absorption element 50 will instead absorb the liquid matrix in the liquid storage cavity 12 through the through hole 411 based on the capillary principle, resulting in loss and waste of the liquid matrix.
[0051] Of course, reference can also be made to Figure 3 and Figure 5 , a support platform 45 can also be provided on the first surface 42 of the first seal 40. The support platform 45 is used to support the fiber absorption element 50, so that a first gap 412 is formed between the fiber absorption element 50 and the first surface 42.
[0052] In one embodiment, the height of the annular boss 43 relative to the first surface 42 can be substantially equal to the height of the support platform 45 relative to the first surface 42, so that the annular boss 43 and the support platform can cooperate to support the fiber absorption element 50.
[0053] In another embodiment, reference can be made to Figure 5, the height of the support platform 45 relative to the first surface 42 is greater than the height of the annular boss 43 relative to the first surface 42, and the annular boss 43 is spaced apart from the fiber absorption element 50 and has no contact with the fiber absorption element 50, thereby forming a second gap 44 between the annular boss 43 and the fiber absorption element 50. In this embodiment, the height of the annular boss 43 relative to the first surface 42 may be D1, and the height of the support platform 45 relative to the first surface 42 is greater than D1. In this embodiment, the annular boss 43 may not have a notch 431.
[0054] In some embodiments, see Figure 4 The aerosol generating device 100 further includes a liquid storage cotton 60, which is disposed in the liquid storage chamber 12 and is used to absorb the liquid matrix to keep the liquid matrix in the liquid storage chamber 12. A clearance space 61 is provided between the first sealing member 40 and the end of the liquid storage cotton 60, and the through hole 411 and the liquid storage cotton 60 are arranged at intervals through the clearance space 61, and the through hole 411 communicates with the first gap 412 and the clearance space 61. By providing the clearance space 61 between the first sealing member 40 and the liquid storage cotton 60, on the one hand, space can be reserved to accommodate the volume of the liquid storage cotton 60 when it expands, and on the other hand, the liquid storage cotton 60 can be prevented from directly abutting against the through hole 411, and the liquid matrix on the liquid storage cotton 60 directly flows from the through hole 411 to the first gap 412.
[0055] In some embodiments, see Figure 4 The first sealing member 40 is further provided with a blocking portion 46 arranged around the through hole 411, and the blocking portion 46 extends toward the liquid storage cotton 60. The blocking portion 46 can ensure that there is a certain distance between the opening of the through hole 411 and the top wall of the clearance space 61. When the aerosol generating device 100 is inverted or tilted, the liquid matrix in the liquid storage chamber 12 that is free from the liquid storage cotton 60 will be blocked at the top of the clearance space 61 and will not enter the through hole 411 to block the through hole 411, thereby ensuring that the through hole 411 can be effectively ventilated and minimizing the leakage of the liquid matrix.
[0056] In some embodiments, see Figure 1 and Figure 2, the liquid storage cavity 12 is provided with a second opening 122 opposite to the first opening 121. The aerosol generating device 100 further includes an airway tube 70 and a second seal 80. At least a part of the main airway 71 is formed in the airway tube 70. At least a part of the airway tube 70 is inserted through the liquid storage cavity 12. The end of the airway tube 70 is connected with an atomization core 20. The side wall of the atomization core 20 is provided with liquid guiding holes 21. The liquid matrix on the liquid storage cotton 60 flows to the atomization core 20 through the liquid guiding holes 21 and is heated to form aerosol. The second seal 80 is arranged at the second opening 122. At least a part of the liquid storage cavity 12 is arranged between the first seal 40 and the second seal 80. The second seal 80 is in a sealed connection with both the housing assembly 10 and the airway tube 70, so as to prevent the liquid matrix from leaking from the second opening 122. Among them, the first opening 121 and the second opening 122 are arranged at the end of the liquid storage cavity 12, which can facilitate the installation of the liquid storage cotton 60 in the liquid storage cavity 12. In other embodiments, the liquid storage cavity 12 may be provided with only the first opening 121.
[0057] In some embodiments, please refer to Figure 2 and Figure 4 , the mouthpiece 11 includes an air inlet 111 communicating with the outside and an air guide tube 112 communicating the air inlet 111 with the main airway 71. One end of the air guide tube 112 defines the boundary of the air inlet 111, and the other end of the air guide tube 112 abuts against the fiber absorption element 50. Thus, the fiber absorption element 50 can be held between the mouthpiece 11 and the first seal 40.
[0058] In some embodiments, please refer to Figure 2 , the mouthpiece 11 further includes a housing 113. The air guide tube 112 is arranged inside the housing 113 and is spaced from the housing 113, so that there is a cavity 1131 between the outer wall surface of the air guide tube 112 and the housing 113, which can reduce the amount of raw materials used when manufacturing the mouthpiece 11 and helps to reduce costs.
[0059] In such as Figure 4In the illustrated embodiment, the aerosol generating device 100 further includes a shielding sheet 90. The shielding sheet 90 covers the surface of the fibrous absorption element 50 facing away from the first seal 40, that is, the shielding sheet 90 is located between the mouthpiece 11 and the fibrous absorption element 50. The shielding sheet 90 is generally in a plate-like structure. The shielding sheet 90 is configured to block the aerosol in the main airway 71 from entering the cavity 1131 through the second gap 44, the first gap 412, and the fibrous absorption element 50, so as to avoid the formation of condensate in the cavity 1131 and reduce the loss of the aerosol. Of course, the shielding sheet 90 can also prevent the liquid absorbed by the fibrous absorption element 50 from entering the cavity 1131. In this embodiment, the outer shell 113 of the mouthpiece 11 can be transparent. Under the shielding of the shielding sheet 90, the transparency of the outer shell 113 can be maintained, so that during the long-term use of the aerosol generating device 100, the aerosol generating device 100 has a good appearance.
[0060] In some embodiments, referring to Figure 2 , the shielding member 30 includes a soft plug. A part of the soft plug is removably disposed in the air duct 112, and the soft plug is in interference fit with the air duct 112 so that the soft plug can be fixed on the mouthpiece 11 to ensure that the mouthpiece 11 and the air duct 112 are not contaminated and blocked by external debris during transportation or storage. A part of the soft plug is exposed to the outside for the user to operate. For example, during the inhalation of the aerosol, the user pulls out the soft plug to communicate the main airway 71 with the outside, so as to ensure that the aerosol generated at the atomization core 20 can smoothly pass through the mouthpiece 11.
[0061] In the aerosol generating device 100 according to the embodiment of the present application, it includes a housing assembly 10, an atomization core 20, and a shielding member 30. The housing assembly 10 includes a mouthpiece 11 and a liquid storage cavity 12 formed inside the housing assembly 10. The liquid storage cavity 12 is used for storing a liquid matrix. The liquid storage cavity 12 is in liquid guiding communication with the atomization core 20 to provide the liquid matrix for the atomization core 20 to generate aerosol. There is a main air passage 71 between the atomization core 20 and the mouthpiece 11. The main air passage 71 is used for guiding the aerosol generated by the atomization core 20 to the mouthpiece 11 for the user to inhale. The shielding member 30 is connected to the mouthpiece 11, and the mouthpiece 11 is configured to communicate with the outside of the aerosol generating device 100 and the main air passage 71 when the shielding member 30 is removed or when the shielding member 30 is broken. Among them, the liquid storage cavity 12 and the main air passage 71 are in air guiding communication to balance the air pressure between the main air passage 71 and the liquid storage cavity 12. In the aerosol generating device 100 of the present application, by arranging the liquid storage cavity 12 and the main air passage 71 to be in air guiding communication, when the temperature and pressure outside the aerosol generating device 100 cause the pressure and temperature in the liquid storage cavity 12 to increase, the gas in the liquid storage cavity 12 can be discharged to the main air passage 71 in time to balance the air pressure inside the liquid storage cavity 12, thereby preventing the air pressure inside the liquid storage cavity 12 from being too high and pressing out and leaking the liquid matrix from the liquid guiding connection between the liquid storage cavity 12 and the atomization core 20.
[0062] It should be noted that the shielding member 30 is optional rather than essential.
[0063] The above are only the embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present application by the same token.
