Description

Technical Field

[0002] At present, most aerosol generating devices adopt side atomization, that is, the heating element is placed sideways in the atomizer, and the aerosol generating matrix in the oil storage tank (storage chamber) contacts one side of the heating element and enters the other side of the heating element to be heated by the heating element to generate aerosol. A ventilation channel is usually provided in the oil storage tank, and the ventilation channel is used to allow external gas to enter the oil storage tank to balance the air pressure in the oil storage tank. However, in the process of external gas entering the oil storage tank from the ventilation channel, large bubbles are easily accumulated at the outlet of the ventilation channel. The large bubbles will hinder the flow of the aerosol generating matrix in the oil storage tank toward the heating element, resulting in less aerosol generating matrix near the heating element, and the user will experience the problem of burning during the inhalation process.

The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0036] At present, most aerosol generating devices adopt a side atomization method, that is, the heating element is placed sideways in the atomizer, and the aerosol generating matrix in the oil storage tank (storage chamber) contacts one side of the heating element and enters the other side of the heating element to be heated by the heating element to generate an aerosol. A ventilation channel is usually provided in the oil storage tank, and the ventilation channel is used to allow external gas to enter the oil storage tank to balance the air pressure in the oil storage tank. However, in the process of external gas entering the oil storage tank from the ventilation channel, large bubbles are easily accumulated at the outlet of the ventilation channel. The large bubbles will hinder the flow of the aerosol generating matrix in the oil storage tank toward the heating element, resulting in less aerosol generating matrix near the heating element, and the user will have a burning problem during the inhalation process. In order to solve this problem, the embodiment of the present application provides an atomizer 100( Figure 2 ) and aerosol generating device 1000 ( Figure 1 shown).

[0037] See also Figure 1 The aerosol generating device 1000 of the embodiment of the present application includes a battery assembly 300 and an atomizer 100, and the atomizer 100 is electrically connected to the battery assembly 300. The battery assembly 300 can be used to supply power to the heating element 30 in the atomizer 100, so that the heating element 30 of the atomizer 100 can generate heat to heat the aerosol generating substrate.

[0038] See also Figures 2 to 5The atomizer 100 of the embodiment of the present application includes a storage element 10 and a heating element 30. The storage element 10 is provided with a storage cavity 11 and a ventilation channel 13. The storage element 10 includes a guide portion 15. The ventilation channel 13 passes through the bottom of the storage element 10 and is connected to the storage cavity 11. The guide portion 15 is arranged at the bottom of the storage element 10 and surrounds the ventilation channel 13. The surface of the guide portion 15 facing the ventilation channel 13 is a curved surface (please refer to the embodiment of the present invention). Figure 8 The heating element 30 is mounted on the storage element 10 , and the heating element 30 is used to heat the aerosol generating substrate flowing from the storage chamber 11 to the heating element 30 to generate aerosol.

[0039] Specifically, see Figure 2 The atomizer 100 of the present application is a structure for heating an aerosol-generating substrate by powering on to generate an aerosol for a user to inhale. The atomizer 100 may heat the aerosol-generating substrate by, but is not limited to, resistive heating, microwave heating, or laser irradiation heating.

[0040] Please combine Figure 1 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 solutes are common organic solutes and / or inorganic solutes 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 Figures 3 to 6 The storage element 10 is a structure for storing an aerosol generating matrix, and the storage element 10 is also used to allow aerosols and gases to flow therethrough. The storage cavity 11 is used for storing the aerosol producing matrix therein. The cross-sectional shape of the storage element 10 may be, but is not limited to, circular, elliptical, triangular, quadrilateral or other polygonal shapes. The cross-sectional shape of the storage element 10 of the present application is roughly circular, that is, the storage element 10 is roughly a cylindrical structure. The material of the storage element 10 may be, but is not limited to, metal or plastic. In the case where the material of the storage element 10 is metal, the structural strength of the storage element 10 is high and the service life is long. In the case where the material of the storage element 10 is plastic, the cost of the storage element 10 is low, and the weight is light, and it is easy to carry. The material of the storage element 10 of the present application is plastic.

[0042] See also Figure 4 , Figure 5 and Figure 7 The first end 131 of the ventilation channel 13 of the embodiment of the present application is located in the storage cavity 11, and the second end 133 is located outside the storage cavity 11. The ventilation channel 13 is used to allow external gas to enter the storage cavity 11 to balance the air pressure in the storage cavity 11. During the user's inhalation, the aerosol generating substrate in the storage cavity 11 flows to the heating element 30 and is heated by the heating element 30 to form an aerosol. The aerosol generating substrate in the storage cavity 11 is continuously consumed. At this time, the external gas enters the storage cavity 11 from the ventilation channel 13, which can balance the air pressure in the storage cavity 11, so that the aerosol generating substrate in the storage cavity 11 can flow smoothly to the heating element 30, which can avoid the problem of no aerosol generating substrate or less aerosol generating substrate around the heating element 30, and the problem of burning when the user inhales.

[0043] See also Figure 4 , Figure 5 , Figure 7 and Figure 8 During the user's inhalation, external gas enters the storage chamber 11 from the ventilation channel 13 in the form of bubbles. If multiple bubbles gather at the first end 131 of the ventilation channel 13, multiple bubbles are easily accumulated to form large bubbles. Large bubbles will hinder the aerosol generating matrix in the storage chamber 11 from flowing toward the heating element 30, resulting in no aerosol generating matrix or less aerosol generating matrix near the heating element 30. The user is prone to burn problems during the inhalation process, and the user experience is poor. In the length direction X of the atomizer 100, the guide part 15 is used to guide the bubbles in the ventilation channel 13 upward. The guide part 15 can make the bubbles in the ventilation channel 13 flow into the storage chamber 11 and separate from the ventilation channel 13, thereby avoiding the bubbles from gathering at the first end 131 of the ventilation channel 13 and avoiding the formation of large bubbles, so as to ensure that the aerosol generating matrix in the storage chamber 11 can flow smoothly to the heating element 30. Preferably, the surface of the guide portion 15 facing the ventilation channel 13 is an arcuate surface. When the bubbles in the ventilation channel 13 come into contact with the arcuate guide portion 15, the arcuate guide portion 15 can play a better guiding role for the bubbles due to its tension, so that the guide portion 15 can guide the bubbles in the ventilation channel 13 upward, so that the bubbles flow from the first end 131 of the ventilation channel 13 into the storage cavity 11, avoiding the bubbles from gathering at the first end 131 of the ventilation channel 13.

[0044] See also Figure 5 and Figure 8, when the aerosol generating substrate is sesame oil, the diameter of the cross section of the ventilation channel 13 is at least greater than 1 mm. At this time, during the user's inhalation, the external gas enters the ventilation channel 13 to form bubbles, and can enter the storage chamber 11 in the form of bubbles, so that the aerosol generating substrate in the storage chamber 11 flows smoothly to the heating element 30. When the diameter of the cross section of the ventilation channel 13 is less than 1 mm, the resistance of the inner wall surface of the ventilation channel 13 is relatively large. During the user's inhalation, it is difficult for the external gas to enter the ventilation channel 13 and form bubbles in the ventilation channel 13. In addition, the bubbles formed at this time are also relatively small. The small bubbles coming out of the first end 131 of the ventilation channel 13 are not easy to move along the curved surface of the guide portion 15, and the curved surface of the guide portion 15 has a poor guiding effect on the small bubbles. It is understandable that the diameter of the cross section of the ventilation channel 13 cannot be too large. In the case where the diameter of the cross section of the ventilation channel 13 is too large, when the user is inhaling, after the external gas enters the ventilation channel 13, the bubbles formed in the ventilation channel 13 are relatively large, and the buoyancy of the large bubbles coming out of the first end 131 of the ventilation channel 13 is greater than the tension, and the large bubbles are easy to directly break away from the guide part 15, and the arc surface of the guide part 15 has a poor guiding effect on the large bubbles. In addition, when the large bubbles move to the vicinity of the heating element 30, the large bubbles will hinder the aerosol generating matrix in the storage chamber 11 from flowing to the heating element 30, and the aerosol generating matrix near the heating element 30 will be insufficient, and the problem of burning will occur when the user inhales. The specific parameters of the cross section of the ventilation channel 13 can be designed according to different types of aerosol generating matrix, and are not limited here.

[0045] See also Figures 3 to 5 , the heating element 30 is a structure that can generate heat when powered. When the battery assembly 300 supplies power to the heating element 30, the heating element 30 can generate heat to heat the aerosol generating matrix located near the heating element 30, and the heated aerosol generating matrix can generate aerosol. The heating element 30 can be a porous ceramic material, and 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 heating element 30 is installed at the bottom of the storage element 10, and the heating element 30 is at least partially connected to the storage cavity 11, so that the aerosol generating matrix in the storage cavity 11 can contact the heating element 30 and 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 an aerosol for the user to inhale.

[0046] The atomizer 100 may further include a seal, which is disposed around the heating element 30 and is used to seal the gap between the heating element 30 and the storage element 10. The seal may be made of materials such as rubber, silicone, plastic or synthetic fiber. Preferably, the number of seals may be two. When the number of seals is two, the sealing effect of the seal is better. The seal can prevent the aerosol generating substrate in the storage cavity 11 from flowing out of the gap between the heating element 30 and the storage element 10, thereby avoiding the waste of the aerosol generating substrate.

[0047] In the atomizer 100 of the embodiment of the present application, during the inhalation process of the user, the external gas enters the ventilation channel 13 in the form of bubbles. The arc-shaped guide portion 15 can guide the bubbles in the ventilation channel 13 into the storage chamber 11 and separate from the ventilation channel 13, thereby preventing multiple bubbles from accumulating near the ventilation channel 13 to form large bubbles, and the aerosol generating matrix in the storage chamber 11 can flow smoothly to the heating element 30. The aerosol generating matrix near the heating element 30 is relatively sufficient, which can prevent the problem of burning when the user inhales.

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

[0049] See also Figure 5 and Figure 8 In the length direction X of the atomizer 100, the guide portion 15 is arranged at the bottom of the storage element 10 and extends toward the storage cavity 11. The highest point of the guide portion 15 is higher than the first end 131 of the ventilation channel 13, so that the guide portion 15 can guide the bubbles in the ventilation channel 13 into the storage cavity 11 and away from the ventilation channel 13, which can avoid the problem of multiple bubbles gathering near the ventilation channel 13 to form large bubbles. In some embodiments, the guide portion 15 is a closed annular structure surrounding the ventilation channel 13. The inner side surface of the closed annular structure is a curved surface, and the inner side surface (curved surface) of the guide portion 15 can play a good guiding role on the bubbles in the ventilation channel 13, so that the bubbles can leave the ventilation channel 13 and enter the storage cavity 11. In other embodiments, the guide portion 15 partially surrounds the ventilation channel 13. At this time, the side of the guide portion 15 facing the ventilation channel 13 is a curved surface, which can play a good guiding role on the bubbles in the ventilation channel 13, so that the bubbles can escape from the ventilation channel 13 and enter the storage chamber 11. At this time, the material used for the guide portion 15 is also less, which can save material costs, and the atomizer 100 is also lighter as a whole, which is convenient for users to carry. The guide portion 15 of the embodiment of the present application partially surrounds the ventilation channel 13.

[0050] See also Figure 4 , Figure 5 and Figure 8In some embodiments, the ventilation channel 13 is staggered with the heating element 30 in the longitudinal direction X of the vertical atomizer 100. At this time, the ventilation channel 13 is far away from the heating element 30, and the bubbles coming out of the first end 131 of the ventilation channel 13 are not easy to move to the vicinity of the heating element 30, thereby preventing the bubbles entering the storage chamber 11 from the ventilation channel 13 from flowing to the vicinity of the heating element 30 to hinder the aerosol generation substrate from flowing to the heating element 30.

[0051] See also Figure 4 , Figure 5 , Figure 7 and Figure 8 Furthermore, in some embodiments, the storage element 10 also includes a blocking portion 17, which is disposed on the top surface of the ventilation channel 13, and the blocking portion 17 is located between the heating element 30 and the guide portion 15, and the blocking portion 17 is used to block the bubbles guided by the guide portion 15 from moving toward the direction close to the heating element 30.

[0052] In the vertical direction X of the atomizer 100, when the ventilation channel 13 and the heating element 30 are staggered, the blocking portion 17 is arranged between the heating element 30 and the guide portion 15. During the user's inhalation, external gas enters the ventilation channel 13 in the form of bubbles, and the arc surface of the guide portion 15 guides the bubbles in the ventilation channel 13 so that the bubbles enter the storage cavity 11 from the first end 131 of the ventilation channel 13. The blocking portion 17 is used to block the bubbles flowing out from the first end 131 of the ventilation channel 13 from moving toward the heating element 30. In this way, on the one hand, it can be avoided that the bubbles flow to the vicinity of the heating element 30 to hinder the aerosol generating matrix from flowing to the heating element 30, and on the other hand, it can be avoided that the bubbles block the surface of the heating element 30, so that the surface of the heating element 30 contacts less aerosol generating matrix, and the problem of burning occurs when the user inhales.

[0053] See also Figure 4 , Figure 5 , Figure 7 and Figure 8In some embodiments, in the length direction X of the atomizer 100, the height of the blocking portion 17 is the same as the height of the guide portion 15. At this time, the blocking portion 17 has a better blocking effect on the bubbles guided by the guide portion 15, and the blocking portion 17 can effectively block the bubbles guided by the curved surface of the guide portion 15 from moving toward the heating element 30, so that the aerosol-generating matrix in the storage chamber 11 can flow smoothly to the heating element 30, which can avoid the problem of burning during the user's inhalation. In other embodiments, in the length direction X of the atomizer 100, the blocking portion 17 is higher than the guide portion 15. At this time, the blocking portion 17 has a better blocking effect on the bubbles guided by the guide portion 15. On the one hand, the blocking portion 17 can effectively block the bubbles guided by the curved surface of the guide portion 15 from moving toward the direction close to the heating element 30. On the other hand, the partial structure of the blocking portion 17 that is higher than the guide portion 15 can also block the bubbles that have separated from the guide portion 15 from moving toward the direction close to the heating element 30, thereby further avoiding the problem of bubbles flowing toward the vicinity of the heating element 30 to hinder the aerosol generating matrix in the storage cavity 11 from flowing toward the heating element 30.

[0054] See also Figure 4 , Figure 5 , Figure 7 and Figure 8 In some embodiments, the blocking portion 17 includes a first side surface 171 facing the ventilation channel 13, a second side surface 173 opposite to the first side surface 171, and a top surface 175 connecting the first side surface 171 and the second side surface 173. The blocking portion 17 is provided with an opening 177, and the opening 177 passes through the first side surface 171, the second side surface 173 and the top surface 175.

[0055] Among them, the opening 177 is used for the aerosol generating substrate in the storage chamber 11 to flow into the ventilation channel 13. In the length direction X of the atomizer 100, the opening 177 is recessed downward from the top surface 175 of the blocking portion 17. Preferably, the lowest point of the opening 177 can be flush with the top surface 175 of the ventilation channel 13. At this time, in the case where there is less aerosol generating substrate in the storage chamber 11, the aerosol generating substrate in the storage chamber 11 can still flow into the ventilation channel 13 through the opening 177, which can avoid the problem of no aerosol generating substrate or less aerosol generating substrate in the ventilation channel 13. In the case where there is no aerosol generating substrate or less aerosol generating substrate in the ventilation channel 13, the ventilation channel 13 will be connected to the external atmosphere, so that the storage chamber 11 will be connected to the external atmosphere, and the aerosol generating substrate in the storage chamber 11 will leak out of the storage chamber 11 through the heating element 30, resulting in a waste of aerosol generating substrate.

[0056] See also Figures 3 to 5In some embodiments, the storage element 10 is further provided with an air guide cavity 19 which is not connected to the storage cavity 11; the atomizer 100 further includes a bracket 50, which is connected to one end of the storage element 10 on which the heating element 30 is installed, and the bracket 50 and the storage element 10 together form an atomization cavity 51, and the atomization cavity 51 is connected to the air guide cavity 19 and the ventilation channel 13, and the air guide cavity 19 is used to guide the aerosol in the atomization cavity 51 to flow out of the atomizer 100.

[0057] The bracket 50 is detachably connected to the storage element 10, wherein the detachable connection method includes but is not limited to a snap connection, a threaded connection or a screw connection. The atomization chamber 51 is used for the heating element 30 to heat the aerosol generating matrix therein, and the heated aerosol generating matrix generates an aerosol. The air guide chamber 19 is used for the aerosol and gas in the atomization chamber 51 to flow out of the atomizer 100 to be inhaled by the user. Preferably, the volume of the storage chamber 11 is larger than the volume of the air guide chamber 19, so that more aerosol generating matrix can be stored in the storage element 10. The user does not need to frequently add the aerosol generating matrix to the storage element 10, and the user's experience is better.

[0058] The storage unit 10 may include a body and a partition. The body may be a columnar structure. The partition is installed in the body and divides the cavity of the body into a storage cavity 11 and an air guide cavity 19 that are not connected to each other. The body and the partition may be an integral structure or a split structure. In the case where the body and the partition are an integral structure, the body and the partition can be integrally formed, and the assembly steps of the storage unit 10 are relatively simple. In the case where the body and the partition are split structures, the replacement and maintenance of the partition can be facilitated. At this time, the partition can be detachably or non-detachably installed on the body. Among them, the detachable installation method includes but is not limited to threaded connection, screw connection or snap connection, etc. The non-detachable installation method includes but is not limited to welding, gluing connection or interference fit, etc.

[0059] See also Figures 3 to 5 Furthermore, in some embodiments, the bottom wall of the atomizing chamber 51 is provided with at least one air guide portion 53, and the air guide portion 53 is provided with an air guide port 531 that passes through the bottom wall of the atomizing chamber 51 and the air guide portion 53, and the air guide port 531 is used to guide external gas into the atomizing chamber 51.

[0060] Among them, the air guide portion 53 is used to guide external gas into the atomizing chamber 51. The air guide portion 53 and the bottom wall of the atomizing chamber 51 can be an integral structure or a split structure. In the case where the air guide portion 53 and the bottom wall of the atomizing chamber 51 are an integral structure, the air guide portion 53 and the bottom wall of the atomizing chamber 51 can be integrally formed. At this time, the processing steps of the bracket 50 are relatively simple. In the case where the air guide portion 53 and the bottom wall of the atomizing chamber 51 are a split structure, the air guide portion 53 and the bottom wall of the atomizing chamber 51 are detachably or non-detachably connected. Among them, the detachable installation method includes but is not limited to threaded connection, screw connection or snap connection, etc. The non-detachable installation method includes but is not limited to welding, gluing connection or interference fit, etc.

[0061] A small portion of the aerosol-generating substrate in the storage chamber 11 will flow into the atomizing chamber 51 from the ventilation channel 13 and the micropores of the heating element 30, and this portion of the aerosol-generating substrate will gather at the bottom of the atomizing chamber 51. In the height direction of the atomizer 100, the highest point of the air guide portion 53 is at least higher than the bottom wall of the atomizing chamber 51. At this time, the air guide portion 53 can block the aerosol-generating substrate at the bottom of the atomizing chamber 51 from entering the air guide port 531, thereby preventing the aerosol-generating substrate from blocking the air guide port 531.

[0062] The air guide port 531 is used to allow external gas to enter the atomizing chamber 51. The cross-sectional shape of the air guide port 531 may be, but is not limited to, circular, elliptical, triangular, quadrilateral or other polygonal shapes. During the user's inhalation, external gas enters the atomizing chamber 51 from the air guide port 531 and the air guide port 531, and the gas entering the atomizing chamber 51 carries the aerosol in the atomizing chamber 51 and flows out of the atomizer 100 from the air guide chamber 19 and is inhaled by the user. At the same time, the gas entering the atomizing chamber 51 also enters the ventilation channel 13 in the form of bubbles, and is guided to the storage chamber 11 by the guide portion 15, so that the air pressure in the storage chamber 11 can be balanced, ensuring that the aerosol generating matrix in the storage chamber 11 flows smoothly to the heating element 30.

[0063] The number of air guides 53 includes, but is not limited to, one, two, three, four or more. The number of air guides 53 of the present application includes two, and the number of air guide ports 531 also includes two (a first air guide port 531 and a second air guide port 531). In a plane perpendicular to the length direction X of the atomizer 100, the projection of the first air guide port 531 at least partially overlaps with the projection of the air guide cavity 19, and the projection of the second air guide port 531 is spaced from the projection of the air guide cavity 19. During the user's suction process, the first air guide port 531 can be used for external gas to enter the atomization cavity 51, and the part of the gas carries the aerosol in the atomization cavity 51 out of the air guide cavity 19 and is sucked by the user. The first air guide port 531 can minimize the problem of aerosol contacting the side wall of the bracket 50 and / or the side wall of the air guide cavity 19 and condensing. The second air guide port 531 allows external gas to enter the atomization chamber 51. When the condensed liquid formed by the aerosol falls, the condensed liquid is not easy to fall into the second air guide port 531, and the second air guide port 531 is not easy to be blocked, thereby avoiding the problem that the external gas cannot enter the atomization chamber 51.

[0064] See also Figures 3 to 5 In some embodiments, the atomizer 100 further includes a nozzle 70, which is detachably connected to an end of the storage element 10 that is away from the bracket 50. When the user uses the aerosol generating device 1000, the battery assembly 300 supplies power to the atomizer 100, and the user inhales the aerosol generated in the atomizer 100 through the nozzle 70. The nozzle 70 is provided with a channel 71, and the channel 71 is connected to the air guide cavity 19. When the user inhales, external gas enters the aerosol generating device 1000 from the battery assembly 300, and the gas enters the atomizing cavity 51 from the battery assembly 300 through the air guide port 531. The gas carries the aerosol in the atomizing cavity 51 from the air guide cavity 19 into the channel 71, and flows out from the channel 71 to the outside of the aerosol generating device 1000 for the user to inhale.
