[0037] An aerosol generating device is a small device that can use the heat not burn (Heat Not Burning, HNB) technology to act on an aerosol generating product and generate an aerosol. In current aerosol generating devices, in order to improve the atomization efficiency of the aerosol generating substrate, the heating power of the heating element is usually relatively large. However, when the power of the heating element is relatively large, the noise generated when the heating element is working (atomizing) is relatively large, and the noise transmitted from the heating element to the outside of the aerosol generating device is relatively large. In order to solve this problem, an embodiment of the present application provides a nebulizer 100 ( Figure 1 ) and aerosol generating device 1000 ( Figure 7 shown).

[0038] See also Figures 1 to 3The atomizer 100 of the embodiment of the present application includes an atomizer seat 10, a heating element 30, a liquid storage element 50 and a silencer assembly 70. The atomizer seat 10 is provided with an atomizer chamber 11. The heating element 30 is installed in the atomizer chamber 11. The liquid storage element 50 includes a first end 51 and a second end 53 opposite to each other. The first end 51 of the liquid storage element 50 is connected to the atomizer seat 10. The liquid storage element 50 includes an air guide portion 55. The air guide portion 55 is provided with an air passage 551. The air passage 551 is communicated with the atomizer chamber 11. The silencer assembly 70 is connected to the second end 53 of the liquid storage element 50 and is located outside the liquid storage element 50. The silencer assembly 70 is provided with a channel 71. The channel 71 is communicated with the air passage 551. The silencer assembly 70 is used to reduce the transmission of sound waves in the atomizer 100 to the outside.

[0039] Specifically, please combine Figure 7 The atomizer 100 of the present application is a structure disposed in the aerosol generating device 1000, and is used to energize to heat the aerosol generating substrate to generate an aerosol for the user to inhale. The heating method of the atomizer 100 to heat the aerosol generating substrate may be, but is not limited to, resistive heating, microwave heating, or laser irradiation heating.

[0040] The aerosol generating device 1000 is a structure capable of generating an aerosol by heating an aerosol generating substrate. The aerosol may be visible or invisible and may include vapor (e.g., fine particulate matter in a gaseous state, which is usually liquid or solid at room temperature) and liquid droplets of gas and condensed vapor. The aerosol generating substrate is a product that has been processed and heated to generate an aerosol. The form of the aerosol generating substrate may be liquid, or may be fully solid or semi-solid. In the case where the aerosol generating substrate is liquid, the liquid aerosol generating substrate is a mixed liquid in which substances such as nicotine and nicotine are dissolved, and its solute is a common organic solute and / or inorganic solute such as propylene glycol, vegetable glycerin and pure water. In the present application, the aerosol generating substrate may be a high-viscosity tobacco oil (e.g., sesame oil, etc.), which can generate an aerosol when heated.

[0041] See also Figure 2 and Figure 3 The atomizer seat 10 is a structure for heating and atomizing the aerosol generating substrate therein to form an aerosol. The atomizer chamber 11 is a spatial structure for accommodating the aerosol. After the aerosol generating substrate is heated by the heating element 30, the generated aerosol flows into the atomizer chamber 11 and flows from the atomizer chamber 11 into the airway 551. The atomizer seat 10 may include a shell 17, which is used to be connected to the liquid storage member 50, so that the connection between the atomizer seat 10 and the liquid storage member 50 is relatively stable. The shell 17 is also used to protect other components located in the atomizer seat 10. For example, the shell 17 can be used to protect the heating element 30 located in the atomizer seat 10.

[0042] The heating element 30 is a structure that can generate heat when powered. The heating element 30 generates heat to heat the aerosol generating matrix located near the heating element 30, and the heated aerosol generating matrix can generate an aerosol for the user to inhale. The heating element 30 can be a porous ceramic material. The porous ceramic is usually prepared by mixing a ceramic slurry with a pore-forming agent and then sintering. The sintered ceramic body has a large number of micropores. The aerosol generating matrix can enter the porous ceramic through the micropores. When the heating element 30 generates heat, the aerosol generating matrix that contacts the heating element 30 and enters the micropores will be heated to generate aerosols.

[0043] See also Figure 2 and Figure 3 The liquid storage part 50 is a structure for storing an aerosol-generating matrix. When the user draws inhalation, the aerosol-generating matrix in the liquid storage part 50 flows toward the heating element 30 and enters the micropores of the heating element 30. When the heating element 30 generates heat, the aerosol-generating matrix in the micropores of the heating element 30 absorbs the heat to form an aerosol. The aerosol enters the atomizing chamber 11 and flows out of the airway 551 to the outside of the atomizer 100, so as to facilitate the user's inhalation.

[0044] In the height direction H of the atomizer 100, the first end 51 of the liquid storage member 50 is the lower end, and the lower end of the liquid storage member 50 is connected to the housing 17. Preferably, the first end 51 of the liquid storage member 50 is detachably connected to the housing 17, so that it is convenient to disassemble and repair when the atomizer seat 10 or the liquid storage member 50 is damaged. Among them, the detachable connection method includes but is not limited to threaded connection, screw connection or snap connection. The second end 53 of the liquid storage member 50 is the upper end, and the upper end of the liquid storage member 50 is connected to the silencer assembly 70. The second end 53 of the liquid storage member 50 is detachably or non-detachably connected to the silencer assembly 70, wherein the detachable installation method includes but is not limited to threaded connection, screw connection or snap connection. Non-detachable installation methods include but are not limited to welding, gluing connection or interference fit.

[0045] The air guide 55 is a structure for guiding the aerosol in the atomizing chamber 11 to the outside of the atomizer 100 for the convenience of the user to inhale. The liquid storage part 50 also includes a body 59, and the body 59 and the air guide 55 can be an integral structure or a split structure. In the case where the body 59 and the air guide 55 are an integral structure, the body 59 and the air guide 55 can be integrally formed. At this time, the processing steps of the liquid storage part 50 are relatively simple. In the case where the body 59 and the air guide 55 are a split structure, the body 59 and the air guide 55 are detachably or non-detachably connected. The body 59 surrounds the air guide 55, and the gap between the body 59 and the air guide 55 forms a liquid storage chamber 57, which is used to store the aerosol generating matrix therein. The cross-sectional shape of the air guide 55 can be, but is not limited to, circular, elliptical, triangular, quadrilateral or other polygons. The airway 551 is used to allow the aerosol in the atomizer 100 and the external gas (air) to flow out of the atomizer 100.

[0046] See also Figure 2 and Figure 3 When the heating element 30 heats the aerosol-generating matrix, the noise generated by the heating element 30 passes through the silencer assembly 70. The silencer assembly 70 can reduce the output of the noise toward the outside of the atomizer 100, so that the user hears less noise during the inhalation process or the user can hardly hear the noise transmitted from the atomizer 100, and the user has a better experience. The silencer assembly 70 is sleeved on the second end 53 of the liquid storage part 50. When the sound waves generated by the heating element 30 pass through the second end 53 of the liquid storage part 50 during operation, the part of the sound waves will all enter the silencer assembly 70, and thus be intercepted by the silencer assembly 70. The silencer assembly 70 can effectively reduce the noise inside the atomizer 100 from being transmitted to the outside of the atomizer 100. The channel is used for the aerosol in the atomizer 100 and the external gas (air) to flow out of the atomizer 100. During the inhalation process of the user, the aerosol flows from the atomization chamber 11 into the airway 551 , and from the airway 551 into the channel 71 , and finally flows out of the atomization chamber 11 for inhalation by the user.

[0047] In the atomizer 100 of the embodiment of the present application, the silencer assembly 70 is connected to the second end 53 of the liquid storage member 50 and is located outside the liquid storage member 50. When the heating element 30 generates noise during operation, the silencer assembly 70 can reduce the transmission of the sound waves of the heating element 30 to the outside of the atomizer 100, so that during the user's inhalation process, the noise transmitted from the heating element 30 to the outside of the atomizer 100 is small, the noise heard by the user is small, and the user's experience is good.

[0048] The atomizer 100 is further described below with reference to the accompanying drawings.

[0049] See also Figures 3 to 5In some embodiments, the silencer assembly 70 includes a silencer 73, which is connected to the second end 53 of the liquid storage member 50 and is located outside the liquid storage member 50. The silencer 73 includes a top wall 731, a peripheral wall 733 extending from the periphery of the top wall 731, and an extension portion 735. The top wall 731 and the peripheral wall 733 form a cavity, and the extension portion 735 extends from the top wall 731 into the cavity. The silencer 73 is provided with a first channel 737 that passes through the top wall 731 and the extension portion 735. The first channel 737 is connected to the airway 551. The top wall 731, the peripheral wall 733 and the extension portion 735 together form a silencer cavity 75. The silencer cavity 75 is used to reduce the transmission of sound waves in the atomizer 100 to the outside.

[0050] Specifically, the muffler 73 is a structure for reducing the transmission of sound waves in the atomizer 100 to the outside. The peripheral wall 733 of the muffler 73 is detachably or non-detachably connected to the second end 53 of the liquid storage member 50. The material of the muffler 73 can be, but is not limited to, plastic or silicone. The first channel 737 is used for the aerosol and external gas in the atomizer 100 to flow out of the atomizer 100. After the sound waves generated by the heating element 30 when working enter the muffler cavity 75 from the second end 53 of the liquid storage member 50, the sound waves are reflected and interfered with each other inside the muffler cavity 75, causing the main noise spectrum components in the sound waves to interfere and be weakened, so that the muffler cavity 75 can reduce the output of noise. The number of muffler cavities 75 of the present application is two, and the two muffler cavities 75 are surrounded by the top wall 731, the peripheral wall 733 and the extension 735, and the two muffler cavities 75 are spaced apart from each other and surround the extension 735.

[0051] See also Figure 4 and Figure 5 Furthermore, in some embodiments, a partition 77 is provided in the silencing cavity 75 , and the partition 77 is used to divide the silencing cavity 75 into a plurality of silencing sub-cavities 751 , and the plurality of silencing sub-cavities 751 are distributed at intervals and surround the extension portion 735 .

[0052] The partition 77 is connected to the top wall 731, the peripheral wall 733 and the extension 735 of the muffler 73, so that the partition 77 can be stably installed in the muffler cavity 75. The partition 77 and the muffler 73 can be an integral structure or a split structure. In the case where the partition 77 and the muffler 73 are an integral structure, the partition 77 and the muffler 73 can be integrally formed, and in this case, the processing steps of the muffler 73 are relatively simple. In the case where the partition 77 and the muffler 73 are a split structure, the partition 77 can be detachably or non-detachably connected to the muffler 73. In this case, the material of the partition 77 can be the same as the material of the muffler 73, or the material of the partition 77 can be different from the material of the muffler 73.

[0053] The number of the partitions 77 may be, but is not limited to, one, two, three, four or more. When the number of the partitions 77 is one, the partition 77 may be arbitrarily disposed in one of the muffler chambers 75, and the muffler chamber 75 is divided into two muffler sub-chambers 751 spaced apart from each other. When the number of the partitions 77 is two, the two partitions 77 may be respectively disposed in the two muffler chambers 75. In this case, each muffler chamber 75 is divided into two muffler sub-chambers 751 spaced apart from each other, and the four muffler sub-chambers 751 are spaced apart and surround the extension 735. When the number of the partitions 77 is four, the four partitions 77 may be respectively disposed in the two muffler chambers 75. In this case, each muffler chamber 75 is divided into three muffler sub-chambers 751 spaced apart from each other, and the six muffler sub-chambers 751 are spaced apart and surround the extension 735.

[0054] When there are multiple partitions 77, there are multiple silencer sub-cavities 751. When there are multiple silencer sub-cavities 751, after the sound waves generated by the heating element 30 when working enter the silencer 73, the sound waves are dispersed in multiple silencer sub-cavities 751. The sound waves are constantly reflected and interfered in each silencer sub-cavity 751, so that the output of noise can be more effectively reduced. The noise propagated from the heating element 30 to the outside of the atomizer 100 when working is small, and the user's experience when inhaling is better. There are two partitions 77 in the present application, and the two partitions 77 can be respectively arranged in two silencer cavities 75, so that there are four silencer sub-cavities 751 in the present application, which can effectively reduce the output of noise.

[0055] See also Figure 2 and Figure 3 Furthermore, in some embodiments, the silencer assembly 70 also includes a sound absorbing member 79, which is connected to the silencer 73 and / or the liquid storage member 50, and the sound absorbing member 79 is provided with a second channel 791, the first channel 737 is connected to the second channel 791, the channel 71 includes the first channel 737 and the second channel 791, and the sound absorbing member 79 is used to reduce the transmission of sound waves in the atomizer 100 to the outside.

[0056] The sound absorbing member 79 can absorb the sound waves transmitted to the muffler assembly 70 and convert the sound waves into heat energy or other forms of energy, thereby further reducing the transmission of the sound waves in the atomizer 100 to the outside. The noise transmitted from the heating element 30 to the outside of the atomizer 100 is small, the noise heard by the user during inhalation is small, and the user's experience is good.

[0057] The second channel 791 is used to allow the aerosol in the nebulizer 100 and external gas to flow out of the nebulizer 100. The opposite ends of the second channel 791 are respectively connected to the airway 551 and the first channel 737. During the user's inhalation process, the aerosol in the atomization chamber 11 enters the airway 551, flows from the airway 551 into the second channel 791, and then flows into the first channel 737 through the second channel 791, and finally flows out of the nebulizer 100 for the user to inhale.

[0058] See also Figure 2 and Figure 3 In some embodiments, the sound absorbing member 79 is a porous medium. At this time, after the sound wave enters the sound absorbing member 79, the sound wave will continue to bounce in the multiple micropores of the sound absorbing member 79 until the sound wave is absorbed by the sound absorbing member 79. In the case where the sound absorbing member 79 is a porous medium, the sound absorbing member 79 can be, but is not limited to, porous sound absorbing cotton, porous ceramics, porous plastics, or porous metals.

[0059] See also Figure 3 In some embodiments, the sound absorbing member 79 is disposed between the second end 53 of the liquid storage member 50 and the extension portion 735, and the opposite ends of the sound absorbing member 79 are respectively abutted against the second end 53 of the liquid storage member 50 and one end of the extension portion 735 close to the liquid storage member 50. At this time, there is no need to connect the liquid storage member 50, the silencer 73 and the sound absorbing member 79, and the structures of the liquid storage member 50, the silencer 73 and the sound absorbing member 79 are relatively simple, which is convenient for design and processing. In addition, the aerosol in the airway 551 can flow out of the atomizer 100 directly from the second channel 791 and the first channel 737, and the loss of aerosol is small. When the silencer assembly 70 and the liquid storage member 50 are installed, the sound absorbing member 79 can be placed on the second end 53 of the liquid storage member 50 first, and then the silencer 73 is connected to the liquid storage member 50. The second end 53 of the liquid storage member 50 and the extension portion 735 jointly clamp the sound absorbing member 79 , so that the sound absorbing member 79 can be stably located between the second end 53 of the liquid storage member 50 and the extension portion 735 .

[0060] In other embodiments, the sound absorbing member 79 is sleeved on the extension portion 735, and the opposite ends of the sound absorbing member 79 are respectively in contact with the second end 53 of the liquid storage member 50 and the top wall 731 of the silencer 73. In this case, the installation between the silencer assembly 70 and the liquid storage member 50 is more convenient. The sound absorbing member 79 can be sleeved on the extension portion 735, and the silencer assembly 70 is then connected to the liquid storage member 50. In addition, the aerosol in the airway 551 can directly flow out of the nebulizer 100 from the second channel 791 and the first channel 737, and the loss of the aerosol is relatively small.

[0061] In some other embodiments, the sound absorbing member 79 is sleeved on the extension portion 735, the sound absorbing member 79 is spaced from the second end 53 of the liquid storage member 50, and the sound absorbing member 79 is spaced from the top wall 731 of the muffler 73. At this time, in the height direction H of the atomizer 100, the height dimension of the sound absorbing member 79 is small, so that less material is used for the sound absorbing member 79, which can save a certain amount of material cost.

[0062] In some other embodiments, the sound absorbing member 79 is sleeved on the extension portion 735, the sound absorbing member 79 is spaced from the second end 53 of the liquid storage member 50, and the sound absorbing member 79 abuts against the top wall 731 of the muffler 73. At this time, in the height direction of the atomizer 100, the height dimension of the sound absorbing member 79 is small, so that less material is used for the sound absorbing member 79, which can save a certain amount of material cost.

[0063] In some other embodiments, the sound absorbing member 79 is sleeved on the extension portion 735, the sound absorbing member 79 abuts against the second end 53 of the liquid storage member 50, and the sound absorbing member 79 is spaced from the top wall 731 of the muffler 73. At this time, in the height direction of the atomizer 100, the height dimension of the sound absorbing member 79 is small, so that less material is used for the sound absorbing member 79, which can save a certain amount of material cost.

[0064] See also Figure 2 , Figure 3 and Figure 6 In some embodiments, the atomizer seat 10 includes a cover body 13 and a seat body 15 that are combined, and the cover body 13 and the seat body 15 together form an atomizer chamber 11. The cover body 13 is provided with a liquid inlet 131 corresponding to the heating element 30, and the liquid storage chamber 57 is connected to the liquid inlet 131.

[0065] The base 15 is used to support the structure of the heating element 30 and the cover 13 and other components. The cover 13 and the base 15 are detachably connected, and the remaining structures of the atomizer base 10 can be installed on the cover 13 and / or the base 15. The detachable installation method includes but is not limited to threaded connection, screw connection or snap connection. The cover 13 and the base 15 of the present application are snap-fit ​​connection. In other embodiments, the cover 13 and the base 15 can also be integrally formed.

[0066] The liquid inlet 131 is used to supply the aerosol generating substrate to flow from the liquid storage chamber 57 to the heating element 30. The heating element 30 corresponds to the position of the liquid inlet 131, and the aerosol generating substrate can flow directly to the heating element 30 through the liquid inlet 131. The aerosol generating substrate enters the micropores of the heating element 30 and is heated by the heating element 30. The aerosol generated by the heated aerosol generating substrate enters the atomizing chamber 11. The aerosol in the atomizing chamber 11 enters the airway 551 and flows out from the second channel 791 and the first channel 737.

[0067] Preferably, a first seal 40 may be provided between the heating element 30 and the cover 13. The first seal 40 is used to seal the gap between the heating element 30 and the cover 13 to prevent the aerosol-generating matrix in the liquid storage chamber 57 from flowing into the atomizing chamber 11 from the gap between the heating element 30 and the cover 13, thereby reducing or even avoiding the waste of the aerosol-generating matrix. Preferably, the first seal 40 is an annular structure. While sealing the gap, the annular first seal 40 can also allow the aerosol-generating matrix in the liquid storage chamber 57 to enter the heating element 30 through the hollow structure of the first seal 40 to be heated by the heating element 30. The first seal 40 can be made of materials such as rubber, silicone, plastic or synthetic fiber. Among them, the rubber material includes but is not limited to natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber or silicone rubber. When the first sealing member 40 is made of rubber material, the first sealing member 40 is more closely in contact with the heating element 30 and the cover 13 , thereby improving the sealing effect of the first sealing member 40 on the gap between the heating element 30 and the cover 13 .

[0068] See also Figure 2 , Figure 3 and Figure 6 In some embodiments, the atomizer 100 further includes a second seal 20 , which is sleeved on the outer peripheral wall 733 of the cover body 13 and / or the seat body 15 , and is used to seal the gap between the atomizer seat 10 and the liquid storage member 50 .

[0069] Among them, the second seal 20 is used to prevent the aerosol-generating matrix in the liquid storage chamber 57 from flowing into the gap between the atomizer seat 10 and the liquid storage member 50, thereby avoiding the waste of the aerosol-generating matrix. In one embodiment, the second seal 20 is sleeved on the peripheral wall 733 of the cover body 13. At this time, the second seal 20 uses less material, which can save material costs. In another embodiment, the second seal 20 is surrounded by the peripheral wall 733 of the seat body 15. At this time, the second seal 20 uses less material, which can save material costs. In another embodiment, the second seal 20 is sleeved on the peripheral wall 733 of the cover body 13 and the seat body 15. At this time, the second seal 20 has a better sealing effect on the gap between the atomizer seat 10 and the liquid storage member 50, and the second seal 20 can effectively prevent the aerosol-generating matrix in the liquid storage chamber 57 from flowing into the gap between the atomizer seat 10 and the liquid storage member 50.

[0070] The second sealing member 20 can be made of rubber, silicone, plastic or synthetic fiber. The rubber material includes but is not limited to natural rubber, nitrile rubber, fluororubber, polyurethane rubber, EPDM rubber or silicone rubber. When the second sealing member 20 is made of rubber material, the sealing effect of the second sealing member 20 on the gap between the atomizer seat 10 and the liquid storage member 50 can be improved.

[0071] See also Figure 2 , Figure 3 and Figure 6 In some embodiments, a heating layer 31 is provided on the heating element 30, and the atomizer 100 further includes an electrical connector 90, which is mounted on the base 15, one end of the electrical connector 90 is electrically connected to the heating layer 31, and the other end of the electrical connector 90 extends from one end of the base 15 away from the cover body 13.

[0072] Specifically, the heating layer 31 is a structure for generating heat by energizing. The heating layer 31 of the present application is arranged on the side of the heating element 30 facing the atomization chamber 11, so that after the aerosol generating matrix entering the heating element 30 is heated by the heating layer 31, the generated aerosol can enter the atomization chamber 11 and flow out of the atomization chamber 11 for the user to inhale. The heating layer 31 can be, but is not limited to, a heating circuit, a heating film, a heating sheet, a heating wire or a heating net, etc., which is not limited here.

[0073] The electrical connector 90 is used to electrically connect the battery assembly 300 and the heating element 30 of the aerosol generating device 1000 so as to conduct the heating layer 31 with the battery assembly 300. One end of the electrical connector 90 is electrically connected to the heating layer 31, and the other end of the electrical connector 90 extends from the base 15 and is electrically connected to the battery assembly 300 of the aerosol generating device 1000. When the user inhales, the battery assembly 300 can provide electrical energy to the heating layer 31 of the heating element 30 through the electrical connector 90, so that the heating layer 31 generates heat. The aerosol generating matrix in the heating element 30 absorbs heat to generate aerosol. The electrical connector 90 can be, but is not limited to, an elastic ejector pin, a metal connector or a wire. The electrical connector 90 is firmly mounted on the base 15, so that the electrical connector 90 can stably conduct the heating layer 31 and the battery assembly 300 of the aerosol generating device 1000.

[0074] See also Figure 6 and Figure 7 The aerosol generating device 1000 of the embodiment of the present application includes a battery assembly 300 and the atomizer 100 of the above embodiment, and the atomizer 100 is electrically connected to the battery assembly 300. The battery assembly 300 is used to supply power to the heating element 30, so that the heating element 30 can generate heat to heat the aerosol generating matrix. The battery assembly 300 and the atomizer 100 are detachably connected by means of threads or buckles.

[0075] In the aerosol generating device 1000 of the embodiment of the present application, the silencer assembly 70 is connected to the second end 53 of the liquid storage member 50 and is located outside the liquid storage member 50. When the heating element 30 generates noise during operation, the silencer assembly 70 can reduce the transmission of the sound waves of the heating element 30 to the outside of the atomizer 100, so that during the user's inhalation process, the noise transmitted from the heating element 30 to the outside of the atomizer 100 is small, the noise heard by the user is small, and the user's experience is good.
