[0016] In the atomizer and electronic atomization device provided in the above embodiments, the atomizer includes a main body and a liquid storage member connected to the main body. The liquid storage member and the main body respectively have a first liquid storage tank and a second liquid storage tank.

[0043] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0044] The terms "first", "second" and "third" in this application are only used for descriptive purposes and cannot be understood as indicating or suggesting the quantity or order of the technical features indicated relative to importance or implicitly indicating the indicated technical features. In the embodiments of the present application, all directional indications (such as up, down, left, right, front, back ...) are only used to explain the relative position relationship or movement situation between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or equipment that includes a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or equipment.

[0045] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0046] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be one or more intermediate elements in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0047] See also Figure 1 、 Figure 2 and Figure 3The present invention provides an atomizer 100, comprising a main body 1, a liquid reservoir 2, a heating assembly 3, an air flow channel 4, and a first sealing member 5. The heating assembly 3, the air flow channel 4, and the first sealing member 5 are disposed within the main body 1. The main body 1 and the liquid reservoir 2 are independent components that can be connected in a detachable or non-detachable manner. For example, in some examples, the main body 1 and the liquid reservoir 2 are separated when the product is sold. Upon first use, the user can combine the two to form the atomizer 100, and the two cannot be separated.

[0048] The liquid storage member 2 is connected to the main body 1 and contains a first liquid reservoir 21 for storing a liquid matrix. The main body 1 contains a second liquid reservoir 11 for storing a liquid matrix or receiving a liquid matrix from the first liquid reservoir 21. The liquid storage member 2 is configured to connect the first liquid reservoir 21 with the second liquid reservoir 11 when connected to the main body 1. In some examples, the liquid matrix capacity of the second liquid reservoir 11 is smaller than the liquid matrix capacity of the first liquid reservoir 21. For example, the liquid matrix capacity of the second liquid reservoir 11 can be 1 ml to 2 ml, while the liquid matrix capacity of the first liquid reservoir 21 can be 5 ml to 10 ml. For example, the liquid matrix capacity of the second liquid reservoir 11 can be 2 ml, while the liquid matrix capacity of the first liquid reservoir 21 can be 5 ml, 6 ml, 7 ml, 8 ml, 9 ml, or 10 ml.

[0049] The main body 1 further includes a heating component 3 , which is located inside the main body 1 and is used to heat and atomize the liquid matrix from the second liquid storage tank 11 to generate an aerosol.

[0050] An air flow channel 4 is provided inside the atomizer 100 . At least a portion of the air flow channel 4 is provided inside the main body 1 . The air flow channel 4 is connected to the outside and provides a path for air to flow through the atomizer 100 during the inhalation process.

[0051] The first sealing member 5 is used to seal the second liquid storage tank 11 and is located at an end of the second liquid storage tank 11 away from the first liquid storage tank 21. The first sealing member 5 can be made of a soft plastic or silicone material, and an interference fit can be provided between the first sealing member 5 and the second liquid storage tank 11. Thus, by providing the first sealing member 5 at the end of the second liquid storage tank 11 away from the first liquid storage tank 21, the second liquid storage tank 11 can be sealed to prevent leakage of the liquid matrix inside the second liquid storage tank 11.

[0052] The first sealing member 5 is provided with a ventilation channel 6, which connects the second liquid storage chamber 11 and the air flow channel 4, thereby providing a channel for air to be introduced into the second liquid storage chamber 11 or to be discharged from the second liquid storage chamber 11. By providing the ventilation channel 6 connecting the second liquid storage chamber 11 and the air flow channel 4 on the first sealing member 5, a channel for air to be introduced into the second liquid storage chamber 11 or to be discharged from the second liquid storage chamber 11 can be provided. For example, in high-altitude transportation or negative pressure testing environments, the ventilation channel 6 can adjust the pressure inside the second liquid storage chamber 11 to maintain it at the same level as the external air pressure, thereby preventing excessive pressure inside the second liquid storage chamber 11 from causing the liquid matrix to leak from the heating assembly 3.

[0053] Exemplarily, the liquid matrix can be a nicotine salt solution or a liquid formula containing other alkaloids, or a liquid matrix containing other functional ingredients, such as but not limited to nicotine salt, propylene glycol, glycerol, sweeteners, cooling agents or flavoring agents. The liquid matrix can be heated by the heating component 3 to generate an aerosol that can be inhaled.

[0054] In some embodiments, see Figure 2 、 Figure 4 、 Figure 5 and Figure 6 The ventilation channel 6 may include an air guide hole 61 that passes through the first sealing member 5 and an air guide groove 62 that is connected to the air guide hole 61 and is located on the side of the first sealing member 5 facing away from the second liquid storage chamber 11. The air guide groove 62 may be connected to the air flow channel 4, so that the arrangement of the air guide hole 61 and the air guide groove 62 can provide a channel for air to be introduced into or discharged from the second liquid storage chamber 11, thereby regulating the pressure inside the second liquid storage chamber 11 and preventing the pressure inside the second liquid storage chamber 11 from being too high relative to the external environment, thereby preventing the liquid matrix from leaking from the heating assembly 3. Furthermore, the air guide holes 61 and the air guide grooves 62 are located on the side of the second liquid storage chamber 11 away from the liquid storage element 2. Even if liquid matrix leaks into the air guide holes 61 and / or the air guide grooves 62, a liquid film can form at the air guide holes 61 or the air guide grooves 62. When the liquid film forms, the entire space formed by the connection between the first liquid storage chamber 21 and the second liquid storage chamber 11 can be blocked by the liquid film, thereby forming a sealed space and further preventing leakage of the liquid matrix within the second liquid storage chamber 11. For example, the first sealing member 5 is made of silicone. Because silicone has a hydrophobic or oleophobic effect, it can, to a certain extent, prevent the liquid matrix from entering the air guide holes 61 and / or the air guide grooves 62 and continuing to conduct outward, thereby promoting the formation of the liquid film.

[0055] In some embodiments, see Figure 5The air guide groove 62 can be arranged around the end of the air guide hole 61 away from the liquid storage part 2, and the air guide groove 62 has a main opening away from the air guide hole 61, and a side opening connected to the main opening, so as to ensure that the first sealing member 5 is not completely blocked by other components after being assembled, thereby ensuring the communication between the air guide groove 62 and the air flow channel 4, which is conducive to the second liquid storage tank 11 to achieve gas exchange with the outside world through the air guide hole 61 and the air guide groove 62, so as to realize the regulation of the internal air pressure of the second liquid storage tank 11.

[0056] In some embodiments, the ventilation channel 6 may also only include the air guide hole 61 passing through the first sealing member 5 .

[0057] In some embodiments, see Figure 2 、 Figure 3 、 Figure 7 and Figure 8 The heating assembly 3 is located within the second liquid storage chamber 11. A capillary element 7 for adsorbing and retaining a liquid matrix may also be disposed within the second liquid storage chamber 11. At least a portion of the capillary element 7 is disposed around the heating assembly 3. Exemplarily, the heating assembly 3 may include a heating mesh 31 and liquid-conducting cotton 32 surrounding the heating mesh 31. The capillary element 7 may be disposed around the periphery of the liquid-conducting cotton 32, thereby allowing the liquid-conducting cotton 32 to fully contact the capillary element 7 and transfer the liquid matrix stored within the capillary element 7 to the heating mesh 31, where it is heated to generate an aerosol. Exemplarily, the capillary element 7 may be a liquid-reservoir cotton.

[0058] In some embodiments, see Figure 2 、 Figure 5 and Figure 8, the heating net 31 can include a first heating net 312, a second heating net 313, and a pin 311. The first heating net 312 and the second heating net 313 have connected ends and free ends, and the two connected ends are connected. The free ends can be bent relative to the connected ends, so that the first heating net 312 and the second heating net 313 can be configured as an open tube, and the two free ends are spaced apart. The pin 311 can include a first pin 3111, a second pin 3112 and a third pin 3113 which are spaced apart. The first pin 3111 is connected to the connected end of the first heating body 312 and the second heating body 313; the second pin 3112 is connected to the free end of the first heating body 312; and the third pin 3113 is connected to the free end of the second heating body 313. Therefore, when the first pin 3111 and the second pin 3112 are electrically connected, the first heating net 312 can be started to heat, and when the first pin 3111 and the third pin 3113 are electrically connected, the first heating net 312 and the second heating net 313 can be started to heat simultaneously. Therefore, by switching the specific heating position of the heating net 31, the switching of different working powers of the atomizer 100 can be realized, so that the user can adjust the working power of the atomizer 100 according to the needs, and realize the selection of different aerosol generating amounts.

[0059] In some embodiments, referring to Figure 5 , three spaced apart pin grooves 64 can be formed on the first sealing member 5 corresponding to the pins 311 on the heating net 31, and the three pin grooves 64 can be used to accommodate the first pin 3111, the second pin 3112 and the third pin 3113 respectively. The pin grooves 64 can be used for positioning and protecting the pins 311, preventing the pins 311 from being damaged or short-circuited during use.

[0060] In some embodiments, referring to Figure 7 , an air passage 71 can be formed on the side of the capillary element 7, which penetrates between the two ends of the capillary element 7. The air passage 71 can communicate the air at the upper and lower ends of the second liquid storage chamber 11 close to and away from the liquid storage member 2, so as to balance the air pressure in the second liquid storage chamber 11, preventing the liquid matrix in the second liquid storage chamber 11 from leaking due to excessive air pressure at the end close to the liquid storage member 2.

[0061] In some embodiments, for example when the atomizer 100 is being puffed, a negative pressure can be formed in the internal passage of the heating assembly 3, which can be transmitted to the air cavity below the capillary element 7 and the outer surface of the capillary element 7 through the airflow passage 4 and the air exchange passage 6, and promote the conduction of the liquid substrate in the capillary element 7 from the upper end to the lower end, and further promote the conduction of the liquid in the first liquid storage 21 to the second liquid storage 11 when the liquid content in the upper end is not saturated, so that the liquid substrate in the second liquid storage 11 can be replenished in time while being puffed, and dry burning of the heating assembly 3 can also be prevented.

[0062] In some embodiments, for example when the atomizer 100 is in high-altitude transportation and negative pressure test, the pressure inside the second liquid storage 11 can be relatively large relative to the outside, which can cause the liquid substrate to leak from the position of the heating assembly 3. Therefore, in the present embodiment, the atomizer 100 is provided with the air exchange passage 6, so that when in high-altitude transportation and negative pressure test, the negative pressure of the outside can be transmitted to the second liquid storage 11 through the airflow passage 4 and the air exchange passage 6, so that the outer surface of the capillary element 7 also maintains a negative pressure, i.e. the same as the air pressure of the heating assembly 3 inside the capillary element 7, so that the pressure inside and outside the capillary element 7 is in a state of relative balance, thereby avoiding the leakage of the liquid substrate from the position of the heating assembly 3.

[0063] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3 , the side of the first sealing member 5 facing the capillary element 7 can have a recess 51, and the recess 51 and the capillary element 7 can jointly define an air cavity in communication with the air exchange passage 6. Thus, the air pressure near the liquid storage member 2 and away from the liquid storage member 2 in the second liquid storage 11 can be adjusted through the air cavity and the air exchange passage 6, so as to prevent the air pressure near the liquid storage member 2 from being too large and causing the liquid substrate to leak. In addition, by providing the recess 51, when the amount of liquid substrate in the second liquid storage 11 exceeds the carrying capacity of the capillary element 7, a certain storage space can be provided for the liquid substrate, preventing the liquid substrate from leaking out through the air guide hole 61. Further, the outer periphery of the air guide hole 61 can be provided with a boss 63, and the height of the boss 63 relative to the bottom of the recess 51 away from the liquid storage member 2 has a certain height, so that when a certain amount of liquid substrate is stored in the recess 51, the part of the liquid substrate cannot easily leak through the air guide hole 61.

[0064] In some embodiments, please refer to Figure 4A plurality of protruding support columns 52 may be provided within the air cavity to support the capillary element 7. For example, some of the support columns 52 may be provided within the recessed portion 51, for example, extending from the side of the recessed portion 51 away from the liquid storage element 2 to the side closer to the liquid storage element 2. Furthermore, the height of the support columns 52 may be higher than the edge of the air guide hole 61 to prevent the end of the capillary element 7 away from the liquid storage element 2 from blocking the air guide hole 61, thereby facilitating the formation of the air cavity and maintaining the balance of the air pressure within the second liquid storage tank 11.

[0065] In some embodiments, see Figure 3 、 Figure 9 and Figure 10 The liquid storage member 2 may include a liquid guide member 8, which is located at one end of the liquid storage member 2 near the second liquid storage tank 11. The liquid guide member 8 can at least partially block the first liquid storage tank 21. Exemplarily, one of the liquid storage member 2 and the liquid guide member 8 can be provided with a slot, and the other can be provided with a buckle, and the liquid storage member 2 and the liquid guide member 8 can be connected through the slot and the buckle. The liquid guide member 8 can include at least one liquid guide tube 81 extending away from the first liquid storage tank 21. The liquid guide tube 81 is configured to be at least partially inserted into the main body 1, thereby connecting the first liquid storage tank 21 and the second liquid storage tank 11. The liquid matrix in the first liquid storage tank 21 can be introduced into the second liquid storage tank 11 through the liquid guide tube 81 to replenish the liquid matrix in the second liquid storage tank 11.

[0066] Furthermore, a third sealing member 22 may be provided on the side of the liquid guide member 8 near the first liquid reservoir 21. This third sealing member 22 may be connected to the liquid guide member 8. The third sealing member 22 may be disposed around the liquid guide tube 81 on the liquid guide member 8 near one end of the first liquid reservoir 21. The end of the third sealing member 22 near the first liquid reservoir 21 may abut against the inner wall of the first liquid reservoir 21, thereby sealing the first liquid reservoir 21 and preventing leakage of the liquid matrix from the clearance between the inner wall of the first liquid reservoir 21 and the liquid guide member 8. Furthermore, to facilitate the introduction of the liquid matrix in the first liquid reservoir 21 into the second liquid reservoir 11 via the liquid guide tube 81, a groove may be provided on the third sealing member 22, recessed toward the second liquid reservoir 11. The bottom of this groove closest to the second liquid reservoir 11 may be the opening of the end of the liquid guide tube 81 near the first liquid reservoir 21. Exemplarily, the groove may be a "funnel-shaped" groove. By setting the "funnel-shaped" groove, the liquid matrix in the first liquid storage tank 21 can be fully utilized to avoid waste of resources.

[0067] In some embodiments, two liquid guide tubes 81 may be provided on the liquid guide member 8, and two grooves may be provided on the third sealing member 22. A through hole may be opened in the groove near the bottom of the second liquid storage tank 11, and the through hole may surround the liquid guide tube 81. The inner wall of the through hole may be interference fit with the end of the liquid guide tube 81 near the first liquid storage tank 21.

[0068] In some embodiments, see Figure 3 、 Figure 9 and Figure 10 The end of the liquid conduit 81 is sealed, and a liquid conduit hole 811 for liquid flow can be opened in the side wall of the liquid conduit 81. The diameter of the liquid conduit hole 811 is smaller than the inner diameter of the liquid conduit 81. The portion of the liquid conduit 81 with the liquid conduit hole 811 can be inserted into the interior of the second liquid storage tank 11. When the liquid matrix in the second liquid storage tank 11 is heated and consumed, a certain negative pressure will be generated in the second liquid storage tank 11. This negative pressure will create a certain air pressure difference with the first liquid storage tank 21. This air pressure difference can promote the liquid matrix in the first liquid storage tank 21 to be transferred into the second liquid storage tank 11 through the liquid conduit hole 811, thereby replenishing the liquid matrix in the second liquid storage tank 11 and eliminating the negative pressure. Furthermore, the elimination of this negative pressure is also related to the exchange of gas between the first liquid storage tank 21 and the outside world through the ventilation channel 6. When negative pressure is generated in the first liquid storage tank 21, gas exchange with the outside world can also be carried out through the ventilation channel 6 to achieve air pressure balance in the first liquid storage tank 21. The air pressure balance inside the second liquid storage tank 11 is a dynamic balance process of replenishing the liquid matrix through the first liquid storage tank 21 and exchanging gas with the outside through the ventilation channel 6.

[0069] In addition, since the interior of the heating component 3 can be a vent tube, and the vent tube is connected to the air flow channel 4 (such as the conventional arrangement of the electronic atomization device 100 such as an electronic cigarette, which will not be repeated here), if the ventilation channel 6 is not provided, when the liquid matrix in the second liquid storage tank 11 is excessive or the air pressure is too high, the liquid matrix will leak from the heating component 3 into the vent tube through the capillary element 7, thereby affecting the puffing taste. However, by providing the ventilation channel 6 in the embodiment of the present application, the air pressure balance inside the second liquid storage tank 11 can be adjusted through the ventilation channel 6, so that the liquid matrix in the second liquid storage tank 11 is maintained in a relatively reasonable range, thereby preventing the liquid matrix inside the second liquid storage tank 11 from leaking due to the air pressure difference.

[0070] In some embodiments, see Figure 3 、 Figure 9 、 Figure 10 and Figure 11The main body 1 may further include a shell 13 and a bottom cover 14. At least a portion of the first sealing member 5 is located inside the shell 13. For example, the first sealing member 5 may be located to seal the end of the shell 13 away from the liquid storage member 2, and may be collectively enclosed with the shell 13 to form a second liquid storage tank 11. The bottom cover 14 may be located at an end of the first sealing member 5 away from the liquid storage member 2 and connected to the shell 13. A slot may be provided on one of the bottom cover 14 and the shell 13, and a buckle may be provided on the other to match the slot. The bottom cover 14 is engaged with the shell 13.

[0071] Also, see Figure 11 The end of the housing 13 of the main body 1 near the liquid storage element 2 can be provided with a recessed cavity that is recessed toward the second liquid storage chamber 11. A second sealing member 12 can be disposed within this cavity. The end of the cavity near the liquid storage element 2 can also be provided with an upper cover 15.
