[0039] See also Figure 1 , Figure 1 It is a schematic diagram of the structure of the electronic atomization device provided in this application.

[0040] The electronic atomization device can be used for atomization of liquid substrates. The electronic atomization device includes an atomizer 1 and a battery assembly 2. The atomizer 1 is used to store the substrate to be atomized and atomize the substrate to be atomized to form an aerosol that can be inhaled by the user; the atomizer 1 can be specifically used in different fields, such as medical treatment, electronic aerosolization, etc. The battery assembly 2 includes a battery assembly housing 20, and the battery assembly housing 20 forms an installation space 200, and part of the atomizer 1 is arranged in the installation space 200; the battery assembly 2 is used to power the atomizer 1 and control the operation of the atomizer 1 so that the atomizer 1 can atomize the substrate to be atomized to form an aerosol. The atomizer 1 and the battery assembly 2 can be arranged in an integrated manner or detachably connected, and are designed according to specific needs.

[0041] See also Figure 2 , Figure 2 It is a structural schematic diagram of the first embodiment of the atomizer provided by the present application.

[0042] The atomizer 1 includes an atomizer housing 11, an air outlet pipe 12, and a reinforcing rib 13; and the atomizer housing 11, the air outlet pipe 12, and the reinforcing rib 13 are integrally formed to form a housing 10. In one embodiment, the atomizer housing 11, the air outlet pipe 12, and the reinforcing rib 13 are integrally injection molded. In another embodiment, the atomizer housing 11, the air outlet pipe 12, and the reinforcing rib 13 can also be fixed together to form the housing 10 by means of adhesive or in-mold injection molding.

[0043] The atomizing housing 11 forms a receiving chamber 110, and the air outlet pipe 12 is arranged in the receiving chamber 110; the air outlet pipe 12 is located in the axial direction of the atomizer 1. In other embodiments, the air outlet pipe 12 may deviate from the axial direction of the atomizer 1. A liquid storage chamber 14 is formed between the air outlet pipe 12 and the atomizing housing 11, and an atomizing channel is formed inside the air outlet pipe 12. The liquid storage chamber 14 is arranged around the air outlet pipe 12, and the liquid storage chamber 14 is used to store the matrix to be atomized, and the atomizing channel is used to guide the atomized aerosol out for the user to use. That is, the receiving chamber 110 includes a liquid storage chamber 14. The reinforcing rib 13 is arranged between the atomizing housing 11 and the air outlet pipe 12, specifically, the reinforcing rib 13 is arranged between the inner surface of the atomizing housing 11 and the outer surface of the air outlet pipe 12; it can be understood that one side of the reinforcing rib 13 abuts against the inner surface of the atomizing housing 11, and the other side abuts against the outer surface of the air outlet pipe 12.

[0044] The electronic atomization device is plate-shaped as a whole; that is, the cross-section of the electronic atomization device is roughly rectangular. One way to make the electronic atomization device thinner and lighter is to reduce the thickness of the atomization housing 11, by setting a reinforcing rib 13 between the atomization housing 11 and the air outlet pipe 12, thereby increasing the rigidity of the atomization housing 11 and reducing the deformation of the atomization housing 11 under pressure; thereby avoiding excessive deformation, squeezing the liquid storage chamber 14, squeezing the matrix to be atomized in the liquid storage chamber 14 to the outside, causing leakage, and improving the performance of the electronic atomization device.

[0045] One end of the atomizer housing 11 is provided with a suction hole 112, and the other end is an open end; the suction hole 112 is connected to the air outlet pipe 12, and the user inhales the aerosol through the suction hole 112. The air outlet pipe 12 and the reinforcing rib 13 extend straightly from the end of the atomizer housing 11 provided with the suction hole 112 to the open end thereof; the length of the reinforcing rib 13 is less than the length of the air outlet pipe 12, and the length of the air outlet pipe 12 is less than the length of the atomizer housing 11.

[0046] A first step structure 113 is formed on the outer surface of the atomizer housing 11. When the atomizer 1 is inserted into the battery assembly housing 20, the step of the first step structure 113 abuts against the end of the battery assembly housing 20, so that part of the atomizer 1 is arranged in the installation space 200 formed by the battery assembly housing 20. In other words, the first step structure 113 is used to abut against the battery assembly housing 20 of the battery assembly 2 to limit the atomizer 1. The end of the open end close to the reinforcing rib 13 does not exceed the step of the first step structure 113. In one embodiment, the end of the reinforcing rib 13 away from the suction hole 112 is flush with the step of the first step structure 113. It is understandable that the stiffness of the atomizing housing 11 in this area is improved by reinforcing ribs 13 between the end of the atomizing housing 11 where the suction hole 112 is provided and the step of the first stepped structure 113 to prevent deformation; the atomizing housing 11 in this area is prevented from being deformed by force by the battery assembly housing 20 between the stage of the first stepped structure 113 and the open end of the atomizing housing 11; the reinforcing ribs 13 and the battery assembly housing 20 work together to prevent the deformation of the atomizing housing 11 under pressure, thereby avoiding leakage of the liquid storage chamber 14 caused by deformation. In other embodiments, the length of the reinforcing ribs 13 can be designed as needed. The reinforcing ribs 13 extend from the top of the atomizer 1 to be flush with the step of the first stepped structure 113, or not exceeding the step of the first stepped structure 113. Under the condition of ensuring strength and rigidity, it is convenient for injection molding of the product, improves the qualified rate of the product, reduces costs, and ensures the manufacturability of the mold.

[0047] Specifically, at least two reinforcing ribs 13 are arranged between the atomizing housing 11 and the air outlet pipe 12, and the at least two reinforcing ribs 13 are symmetrically arranged along the outer surface of the air outlet pipe 12. By symmetrically arranging the reinforcing ribs 13, the atomizing housing 11 is subjected to uniform force at various positions under the action of external force, that is, the rigidity of the atomizing housing 11 is uniformly improved.

[0048] See also Figure 3 , Figure 3 It is a schematic diagram of the assembly structure of the reinforcing ribs in the first embodiment of the atomizer provided by the present application.

[0049] At least two reinforcing ribs 13 are arranged between the atomizing housing 11 and the air outlet pipe 12, and the at least two reinforcing ribs 13 are symmetrically arranged in the thickness direction of the atomizer 1. In one embodiment, two reinforcing ribs 13 are arranged between the atomizing housing 11 and the air outlet pipe 12. In the thickness direction of the atomizer 1, the two reinforcing ribs 13 are symmetrically arranged; that is, along the thickness direction, one reinforcing rib 13 is arranged on one side of the air outlet pipe 12, and the other reinforcing rib 13 is arranged on the other side of the air outlet pipe 12, and the two reinforcing ribs 13 are located in the same plane, and the plane where the two reinforcing ribs 13 are located is perpendicular to the width direction of the atomizer 1, such as Figure 3 As shown. Since the span of the side wall of the atomizer housing 11 in the thickness direction is smaller than that in the width direction, the larger the span, the easier it is to deform under force; by symmetrically arranging the reinforcing ribs 13 in the thickness direction, the atomizer housing 11 is prevented from deformation under the action of external force, thereby preventing leakage.

[0050] See also Figure 4 , Figure 4 This is another schematic diagram of the assembly structure of the reinforcing ribs in the first embodiment of the atomizer provided by the present application.

[0051] In another embodiment, the cross-sectional shape of the atomizer 1 is roughly rectangular, and four reinforcing ribs 13 are arranged between the atomizer housing 11 and the air outlet pipe 12, and the four reinforcing ribs 13 are arranged symmetrically with each other. Along the thickness direction of the atomizer 1, two reinforcing ribs 13 are arranged on one side of the air outlet pipe 12, and the other two reinforcing ribs 13 are arranged on the other side of the air outlet pipe 12. The two reinforcing ribs 13 on the same side of the air outlet pipe 12 are located in the same plane, and the plane where the two reinforcing ribs 13 are located is arranged along the diagonal line. The four reinforcing ribs 13 divide the cross-sectional area of ​​the atomizer housing 11 in the axial direction perpendicular to the atomizer 1 into four equal parts, such as Figure 4 shown.

[0052] In other configurations, two reinforcing ribs 13 are provided between the atomizing housing 11 and the air outlet pipe 12, and the reinforcing ribs 13 may also be symmetrically arranged in the width direction of the atomizer 1. The number of the reinforcing ribs 13 and their specific configuration may be designed as required.

[0053] See also Figure 5a , Figure 5a It is a schematic diagram of the structure of the atomizer seat in the first embodiment of the atomizer provided in the present application.

[0054] Continue to see Figure 2As shown in Figure 5, the accommodating chamber 110 formed by the atomizing housing 11 also includes a receiving chamber 111, which is located on the side of the liquid storage chamber 14 away from the suction hole 112, and the end of the receiving chamber 111 away from the suction hole 112 is an open end; that is, the housing 10 is formed with a liquid storage chamber 14, a receiving chamber 111 and an atomizing channel. The atomizer 1 also includes an atomizing seat 15 and an atomizing core 16. The atomizing seat 15 includes an atomizing top seat 151 and an atomizing base 152, and the atomizing top seat 151 and the atomizing base 152 can be connected by a snap-fit ​​structure. For example, a protrusion can be set on the atomizing top seat 151, and a card groove can be set on the atomizing base 152; or a protrusion can be set on the atomizing base 152, and a card groove can be set on the atomizing top seat 151. The atomizing top seat 151 and the atomizing base 152 cooperate to form an installation cavity 153, and the installation cavity 153 is connected to the air outlet pipe 12. The atomizer core 16 is disposed in the mounting cavity 153, and the two ends of the atomizer core 16 are overlapped on the atomizer seat 15, and the middle part of the atomizer core 16 is suspended in the mounting cavity 153; the atomizer core 15 and the atomizer seat 15 are disposed in the receiving cavity 111 and cover the open end thereof. In other words, the atomizer seat 15 is disposed at the open end of the atomizer housing 11 and covers the open end of the atomizer housing 11.

[0055] Specifically, one end of the atomizer seat 15 abuts against the air outlet pipe 12 and the liquid storage chamber 14, and the other end covers the open end of the atomizer housing 11. That is, the atomizer top seat 151 is arranged between the liquid storage chamber 14 and the atomizer base 152; the top wall of the atomizer top seat 151 is provided with a first lower liquid channel 1511, a second lower liquid channel 1512 and a connecting hole 1513, and the first lower liquid channel 1511 and the second lower liquid channel 1512 are arranged on both sides of the connecting hole 1513; one end of the first lower liquid channel 1511 and the second lower liquid channel 1512 are connected to the liquid storage chamber 14, and the other end is connected to the atomizer core 16, so that the substrate to be atomized in the liquid storage chamber 14 is guided to the atomizer core 16 through the first lower liquid channel 1511 and the second lower liquid channel 1512; the connecting hole 1513 is connected to the air outlet pipe 12, and the connecting hole 1513 connects the air outlet pipe 12 and the installation chamber 153. An air inlet 1521 is provided on the atomizing base 152 , and the air inlet 1521 is in communication with the mounting cavity 153 , so that the air inlet 1521 is in communication with the outside and the mounting cavity 153 .

[0056] An atomizing chamber 17 is formed between the atomizing surface of the atomizing core 16 and the atomizing seat 15. The atomizing core 16 is arranged in the mounting chamber 153. The mounting chamber 153 is connected with the air inlet 1521 and the air outlet pipe 12. That is to say, the atomizing chamber 17 is connected with the air inlet 1521 and the air outlet pipe 12. The air inlet 1521, the atomizing chamber 17, the connecting hole 1513, the air outlet pipe 12 and the suction hole 112 form an air flow channel of the atomizer 1. When a user uses the electronic atomizing device and inhales at the suction nozzle hole 112, the outside air enters the atomizing chamber 17 through the air inlet 1521 on the atomizing seat 152, and carries the atomized aerosol of the atomizing core 16 in the atomizing chamber 17 through the connecting hole 1513 into the air outlet pipe 12, and reaches the suction nozzle hole 112 to be inhaled by the user.

[0057] A first sealing member 18 is provided between the liquid storage chamber 14 and the atomizing top seat 151 to achieve sealing between the atomizing seat 15 and the liquid storage chamber 14 and the air outlet pipe 12, so as to prevent the liquid in the liquid storage chamber 14 from leaking into the atomizing chamber 17 or the air outlet pipe 12, thereby affecting the performance of the atomizer 1. The first sealing member 18 includes a top wall and a side wall, wherein the top wall is provided on the surface of the atomizing top seat 151 close to the liquid storage chamber 14, and the side wall is provided on the side wall of the atomizing top seat 151; that is, the side wall of the first sealing member 18 is located between the atomizing top seat 151 and the atomizing housing 11.

[0058] A second sealing member 19 is provided between the atomizing base 152 and the atomizing housing 11; the second sealing member 19 is sleeved on the bottom of the atomizing base 152 and abuts between the atomizing base 152 and the atomizing housing 11. The second sealing member 19 is used to prevent liquid from flowing out of the atomizing housing 11, and to prevent liquid from leaking into the battery assembly 2, thereby affecting the operation of the battery assembly 2.

[0059] See also Figure 5b , Figure 5b It is a schematic diagram of force analysis of the first embodiment of the atomizer provided in this application.

[0060] Under the action of external force, due to the use of a thinner atomizing housing 11, its rigidity is low and it is easy to deform. On the one hand, increasing the reinforcing ribs 13 can improve the rigidity of the atomizing housing 11 and reduce the change in the volume of the liquid storage chamber 14. On the other hand, since the first seal 18 is provided between the atomizing top seat 151 and the liquid storage chamber 14, the side wall of the first seal 18 is located between the atomizing top seat 151 and the atomizing housing 11, and the contact point between the first seal 18 and the atomizing housing 11 is used as a fulcrum, and the open end of the atomizing housing 11 has a tendency to deform to the outer shape, which may cause leakage. Further, a bottom cover 40 is provided at the open end of the atomizing housing 11, and the bottom cover 40 includes a bottom wall and a side wall, and the side wall of the bottom cover 40 is arranged in contact with the outer surface of the atomizing housing 11, and the bottom wall of the bottom cover 40 is arranged in contact with the surface of the atomizing seat 15, that is, the bottom wall of the bottom cover 40 is arranged in contact with the atomizing base 152 away from the surface of the atomizing top seat 151.

[0061] Through the above-mentioned setting mode of the bottom cover 40, the bottom cover 40 limits the direction of the circumference of the atomizer housing 11 perpendicular to the axis of the atomizer 1, preventing the open end of the atomizer housing 11 from warping under pressure, thereby preventing leakage caused by the warping of the open end of the atomizer housing 11; at the same time, the deformation caused by the warping of the open end of the atomizer housing 11 is prevented from causing the size change of the open end of the atomizer housing 11, thereby preventing the atomizer 1 from being unable to be installed in the battery assembly housing 20; at the same time, the first seal 18 and the second seal 19 are pressed tightly, and a pressure perpendicular to the axial direction of the atomizer 1 is applied to them, thereby improving the sealing performance of the thickness and width direction of the atomizer 1, and avoiding the leakage caused by sealing failure. At the same time, the bottom cover 40 also applies a force in the longitudinal direction to improve the longitudinal sealing and limiting effects.

[0062] A second step structure 114 is formed on the outer surface of the atomizer housing 11 near its open end, and the side wall of the bottom cover 40 abuts against the second step structure 114, that is, the end of the side wall of the bottom cover 40 away from its bottom wall abuts against the step of the second step structure 114. By setting the second step structure 114, the outer surface of the atomizer 1 is made flush, which is more conducive to inserting into the battery assembly housing 20, and ensures that the inner surface of the battery assembly housing 20 is the same as the distance between the outer surface of the atomizer 1. It can be understood that the second step structure 114 may not be set; the setting method and size of the second step structure 114 are designed according to needs.

[0063] See also Figure 6 , Figure 6 It is a schematic diagram of the size identification of each component in the atomizer provided in this application.

[0064] In one embodiment, the height of the atomizer seat 15 is L1, and the height of the side wall of the bottom cover 40 is L2, L1:L2=1:0.1~1:0.8; optionally, L1 is 10% of L2. The distance L3 between the end of the reinforcing rib 13 close to the open end of the atomizer housing 11 and the end of the side wall of the bottom cover 40 close to the reinforcing rib 13 is 10~25mm; optionally, the distance is 15mm. The distance L4 between the end of the reinforcing rib 13 close to the open end of the atomizer housing 11 and the end of the atomizer seat 15 close to the suction hole 112 is 3~15mm; optionally, the distance is 10mm. It can be understood that the height of the atomizer seat 15, the number and length of the reinforcing ribs 13, the height of the side wall of the bottom cover 40, the distance between the reinforcing rib 13 and the bottom cover 40, and the distance between the reinforcing rib 13 and the atomizer seat 15 can be designed according to the thickness of the atomizer housing 11 and the volume requirements of the atomizer 1.

[0065] The atomizer core 16 includes a heating element and a porous element. The liquid in the liquid storage chamber 14 enters the porous element through the first lower liquid channel 1511 and the second lower liquid channel 1512. The porous element is used to store the liquid and guide the liquid to the atomization surface of the heating element through capillary action; the heating element is used to heat and atomize the liquid on the atomization surface. The porous element can be made of cotton core or porous ceramic. Since the porous element can guide the liquid through capillary action, a third sealing element 30 is provided on the atomizer core 16 to prevent the liquid from entering the atomization chamber 17 through the capillary action of the porous element, thereby affecting the atomization of the liquid in the liquid storage chamber 14 by the atomizer 1.

[0066] See also Figure 7 and Figure 8 , Figure 7 is a schematic diagram of the assembly of the third sealing member and the atomizing top seat provided in the present application, Figure 8 It is an exploded schematic diagram of the first embodiment of the third sealing member provided in the present application and the atomizer seat.

[0067] The third sealing member 30 is disposed between the atomizer core 16 and the atomizer top seat 151. In the height direction of the atomizer core 16, the third sealing member 30 exposes at least a section of the side surface of the atomizer core 16 to the air flow channel.

[0068] Further, in the thickness direction of the atomizer 1, the atomizer core 16 includes a first surface and a second surface that are opposite to each other; the third seal 30 makes the first surface portion and / or the second surface portion fit with the cavity wall of the installation cavity 153. Specifically, the third seal 30 includes a side wall and a bottom wall, the bottom wall of the third seal 30 is arranged on the surface of the atomizer core 16 away from the air inlet 1521, and the side wall of the third seal 30 is arranged on the side surface of the atomizer core 16. A first notch 31 is arranged on the side wall of the third seal 30, so that the first surface portion and / or the second surface portion of the atomizer core 16 fits with the inner surface of the installation cavity 153.

[0069] By setting the first notch 31 on the third sealing member 30, the first surface portion and / or the second surface portion of the atomizer core 16 are arranged to fit the inner surface of the mounting cavity 153, so that the thickness of the atomizer 1 can be further reduced, and the electronic atomization device can be made thinner and lighter without affecting the heating efficiency of the atomizer core. The atomized aerosol has a better taste. That is, in the thickness direction of the atomizer 1, there is no seal between one of the first surface and the second surface of the atomizer core 16 and the atomization top seat 151, so as to achieve the purpose of thinning. At the same time, since the first notch 31 completely exposes the first surface and / or the second surface of the atomizer core 16, the airflow flows through the entire surface of the first surface and / or the second surface of the atomizer core 16, which can achieve the cooling of the atomizer core 16 and avoid deformation of the atomization shell 11 caused by excessive temperature. Furthermore, since the first surface and / or the second surface of the atomizer core 16 is not blocked by the third sealing member 30, after the inhalation is completed, the path of the condensate in the air outlet pipe 12 flowing back to the porous member of the atomizer core 16 becomes shorter, and the condensate can be absorbed by the porous member more quickly, thereby achieving secondary atomization and reuse of the condensate.

[0070] A second notch 1514 is provided on the side wall of the atomizer top seat 151 corresponding to the first notch 31 , so that at least part of the first surface and / or the second surface of the atomizer core 16 is exposed, and an air passage connecting the communicating hole 1513 and the air inlet 1512 is formed between the inner surface of the accommodating cavity 111 .

[0071] See also Figure 7 , the edge of the third sealing member 30 corresponding to the first surface and / or the second surface does not protrude from the first surface and / or the second surface. In other words, the edge of the third sealing member 30 is flush with the edge of the atomizer core 16 or slightly lower than the edge of the atomizer core 16

[0072] In the first embodiment of the third sealing member 30, the third sealing member 30 only exposes the first surface of the third sealing member 30 completely to the airflow passage except for the portion that is in contact with the cavity wall of the mounting cavity 153; the third sealing member 30 covers the second surface. Further, the portion of the third sealing member 30 corresponding to the second surface is in contact with the inner surface of the housing 10.

[0073] Specifically, only one first notch 31 is provided on the side wall of the third sealing member 30, so that the first surface portion of the atomizer core 16 is fitted with the inner surface of the mounting cavity 153; the side wall of the third sealing member 30 is only provided on the second surface of the atomizer core 16 and the side surface of the atomizer core 16 in the width direction of the atomizer 1.

[0074] Optionally, an air passage connecting the connecting hole 1513 and the air inlet 1521 is formed between the first surface of the atomizer core 16 and the inner surface of the receiving chamber 111, and an air passage connecting the connecting hole 1513 and the air inlet 1521 is formed between the outer surface of the third sealing member 30 corresponding to the second surface of the atomizer core 16 and the inner surface of the receiving chamber 111; that is, both sides of the first surface and the second surface of the atomizer core 16 can allow airflow to pass. In order to make the thickness of the atomizer core 1 as thin as possible, on the premise of satisfying the atomization of the substrate to be atomized, the distance between the first surface of the atomizer core 16 and the inner surface of the receiving chamber 111 is set to be greater than or equal to 0.3 mm; the distance between the outer surface of the third sealing member 30 corresponding to the second surface of the atomizer core 16 and the inner surface of the receiving chamber 111 is set to be greater than or equal to 0.3 mm.

[0075] Optionally, an airway connecting the connecting hole 1513 and the air inlet 1521 is formed only between the first surface of the atomizer core 16 and the inner surface of the receiving chamber 111; and the side wall of the third seal 30 corresponding to the second surface of the atomizer core 16 is fitted with the inner surface of the receiving chamber 111, that is, no airflow will pass through the side wall of the third seal 30 corresponding to the second surface of the atomizer core 16. In order to make the thickness of the atomizer core 1 as thin as possible, the distance between the first surface of the atomizer core 16 and the inner surface of the receiving chamber 111 is set to be greater than or equal to 0.3 mm on the premise of satisfying the atomization of the matrix to be atomized. It can be understood that forming an airway connecting the connecting hole 1513 and the air inlet 1521 only on one side of the first surface or the second surface of the atomizer core 16 is conducive to thinning the thickness of the atomizer core 16, thereby reducing the volume of the electronic atomization device.

[0076] See also Fig. 9 , Fig. 9 It is an exploded schematic diagram of the second embodiment of the third sealing member provided in the present application and the atomizer seat.

[0077] In the second embodiment of the third sealing member 30 , the location and function of the third sealing member 30 are the same as those in the first embodiment, except for the location of the first notch 31 on the third sealing member 30 .

[0078] In this embodiment, the third seal 30 makes the first surface and the second surface of the atomizer core 16 completely exposed to the airflow channel except for the part that is in contact with the cavity wall of the mounting cavity 153. Specifically, two first notches 31 are provided on the side wall of the third seal 30, so that the first surface part and the second surface part of the atomizer core 16 are both in contact with the inner surface of the mounting cavity 153. In other words, the side wall of the third seal 30 is only provided on the side of the atomizer core 16 in the width direction of the atomizer 1, so that the first surface and the second surface of the atomizer core 16 are completely exposed. An airway connecting the connecting hole 1513 and the air inlet 1521 is formed between each of the first surface and the second surface of the atomizer core 16 and the inner surface of the accommodating cavity 111; that is, both sides of the first surface and the second surface of the atomizer core 16 can allow airflow to pass through. It can be understood that, compared with the first embodiment, the second embodiment of the third seal 30 is configured such that the first surface and the second surface of the atomizer core 16 are both fitted with the inner surface of the mounting cavity 153, that is, the third seal 30 is not arranged between the first surface and the second surface of the atomizer core 16 and the inner surface of the mounting cavity 153, so that the atomizer 1 is thinner in its thickness direction, further reducing the volume of the electronic atomization device; and the two first notches 31 expose a larger area of ​​the side of the atomizer core 16, which is more conducive to cooling the atomizer core 16 by the airflow flowing through it; the technical effect that can be achieved by setting the first notch 31 on the third seal 30 is the same as that in the first embodiment and will not be repeated.

[0079] In order to make the thickness of the atomizer core 1 as thin as possible, under the premise of atomizing the substrate to be atomized, the distance between each of the first surface and the second surface of the atomizer core 16 and the inner surface of the receiving cavity 111 is greater than or equal to 0.3 mm.

[0080] See also Fig.10 , Fig.10 It is an exploded schematic diagram of a third embodiment of a third sealing member and an atomizer seat provided in the present application.

[0081] In the second embodiment of the third sealing member 30 , the location and function of the third sealing member 30 are the same as those in the first embodiment, and the difference lies in the structure of the third sealing member 30 .

[0082] In this embodiment, the third sealing member 30 is a sheet-like structure, and openings are provided at positions corresponding to the first lower liquid channel 1511, the second lower liquid channel 1512, and the connecting hole 1513; that is, the third sealing member 30 is provided on the surface of the atomizer core 16 away from the air inlet 1521, and the side of the atomizer core 16 is completely exposed. An air passage connecting the connecting hole 1513 and the air inlet 1521 is formed between each of the first surface and the second surface of the atomizer core 16 and the inner surface of the accommodating cavity 111; that is, both sides of the first surface and the second surface of the atomizer core 16 can allow airflow to pass through. It can be understood that, compared with the first embodiment, the third embodiment of the third seal 30 has the same effect as the first embodiment, because the side surfaces of the atomizer core 16 are fitted with the inner surface of the mounting cavity 153, that is, the third seal 30 is not arranged between the side surfaces of the atomizer core 16 and the inner surface of the mounting cavity 153, so that the atomizer 1 is thinner in its thickness direction and width direction, and the volume of the electronic atomization device is further reduced; and the third seal 30 completely exposes the side surfaces of the atomizer core 16, which is more conducive to the cooling of the atomizer core 16 by the airflow flowing through it; the technical effect that can be achieved by the third seal 30 completely exposing the side surfaces of the atomizer core 16 is the same as the technical effect that can be achieved by setting the first notch 31 on the third seal 30 in the first embodiment, and will not be repeated.

[0083] In order to make the thickness of the atomizer core 1 as thin as possible, under the premise of atomizing the substrate to be atomized, the distance between each of the first surface and the second surface of the atomizer core 16 and the inner surface of the receiving cavity 111 is greater than or equal to 0.3 mm.

[0084] See also Fig.11 , Fig.12 and Fig.13 , Fig.11 is a schematic diagram of a structure of a part of the second embodiment of the atomizer provided by the present application in the first direction, Fig.12 is a partial second direction structural diagram of the second embodiment of the atomizer provided by the present application, Fig.13 It is a partial cross-sectional schematic diagram of the second embodiment of the atomizer provided by the present application.

[0085] In the second embodiment of the atomizer 1, the structure of the atomizer 1 is basically the same as that of the first embodiment, except that the sealing structures used to achieve the sealing between the atomizer top seat 151 and the liquid storage chamber 14 and the air outlet pipe 12, and the sealing between the atomizer base 152 and the atomizer housing 11 are different.

[0086] In this embodiment, the atomizer 1 includes a sealing assembly 40, which is sleeved on the atomizer seat 15. The sealing assembly 40 includes an atomizer top seat sealing portion 43, an atomizer base sealing portion 44 and a connecting portion 45; the atomizer top seat sealing portion 43 seals between the liquid storage chamber 14 and the atomizer top seat 151; the atomizer base sealing portion 44 seals between the atomizer base 152 and the housing 10; the connecting portion 45 connects the atomizer top seat sealing portion 43 and the atomizer base sealing portion 44; the atomizer top seat sealing portion 43, the atomizer base sealing portion 44 and the connecting portion 45 are integrally formed. It can be understood that one end of the sealing assembly 40 is arranged between the atomizer top seat 151 and the liquid storage chamber 14, that is, the atomizer top seat sealing portion 43 is arranged between the atomizer top seat 151 and the liquid storage chamber 14, and the atomizer top seat 151 and the liquid storage chamber 14 and the air outlet pipe 12 are sealed; the other end of the sealing assembly 40 is arranged between the atomizer base 152 and the inner surface of the shell 10, that is, the atomizer base sealing portion 44 is arranged between the atomizer base 152 and the inner surface of the shell 10, and the atomizer base 152 and the shell 10 are sealed.

[0087] The sealing assembly 40 includes a top wall 41 and an annular side wall 42, and the top wall and the annular side wall are integrally formed; that is, the sealing assembly 40 is integrally formed. It can be understood that the top wall of the atomizing top seat sealing part 43 forms the top wall 41 of the sealing assembly 40, and the side wall of the atomizing top seat sealing part 43, the atomizing base sealing part 44 and the connecting part 45 form the annular side wall 42. By making the sealing assembly 40 integrally formed, the number of components is reduced, the process flow is simplified, and the material cost and assembly cost are reduced; at the same time, since the sealing assembly 40 is integrally formed, the part arranged between the atomizing top seat 151 and the liquid storage chamber 14 and the part arranged between the atomizing base 152 and the cavity wall of the receiving cavity 111 play a limiting role with each other, and can prevent the sealing part between the atomizing base 152 and the cavity wall of the receiving cavity 111 from flanging during the assembly process, improve the air tightness between the atomizing base 152 and the cavity wall of the receiving cavity 111, and then improve the air tightness of the atomizer 1. Optionally, the material of the sealing assembly 40 is silicone.

[0088] The top wall 41 is provided with openings at positions corresponding to the first lower liquid channel 1511, the second lower liquid channel 1512 and the connecting hole 1513 provided on the atomizing top seat 151, so as to expose the first lower liquid channel 1511, the second lower liquid channel 1512 and the connecting hole 1513. The top wall 41 is provided with an extension portion (not shown) at a position corresponding to the connecting hole 1513, and the extension portion extends from the surface of the atomizing top seat 151 close to the liquid storage chamber 14 to the hole wall of the connecting hole 1513, so as to achieve sealing between the air outlet pipe 12 and the hole wall of the connecting hole 1513, that is, to achieve sealing between the atomizing top seat 151 and the air outlet pipe 12; accordingly, an avoidance groove is provided on the outer surface of one end of the air outlet pipe 12 close to the atomizing top seat 151, and is arranged in close contact with the extension portion of the top wall 41, so that the air outlet pipe 12 is partially inserted into the connecting hole 1513.

[0089] The outer surface of the annular side wall 42 close to the liquid storage chamber 14 has a first annular protrusion 421, and the first annular protrusion 421 abuts against the inner surface of the receiving chamber 111 to achieve sealing between the atomizing top seat 151 and the liquid storage chamber 14. The outer surface of the annular side wall 42 away from the liquid storage chamber 14 has a second annular protrusion 422, and the second annular protrusion 422 abuts against the inner surface of the receiving chamber 111 to achieve sealing between the atomizing base 152 and the receiving chamber 111, that is, to achieve sealing between the atomizing base 152 and the housing 10. In other words, the outer surface of the side wall of the atomizing top seat sealing part 43 has a first annular protrusion 421; the outer surface of the atomizing base sealing part 44 has a second annular protrusion 422; the first annular protrusion 421 and the second annular protrusion 422 both abut against the cavity wall of the receiving chamber 111.

[0090] Specifically, in the thickness direction of the atomizer 1, the atomizer core 16 includes a first surface and a second surface opposite to each other; the connecting portion 45 of the sealing assembly 40 exposes at least a section of the first surface and / or the second surface of the atomizer core 16 to the air flow channel. In other words, a through hole 423 is provided on the annular side wall 42 to expose at least a portion of the first surface and / or the second surface of the atomizer core 16, so that an air passage connecting the communication hole 1513 and the air inlet 1521 is formed between the first surface and / or the second surface of the atomizer core 16 and the inner surface of the receiving chamber 111.

[0091] In one embodiment, the connection portion 45 only exposes at least a section of the first surface of the atomizer core 16 to the air flow channel. Further, the third sealing member 30 allows the first surface portion of the atomizer core 16 to be fitted with the inner surface of the mounting cavity 153, and the first surface is completely exposed to the air flow channel except for the portion that is fitted with the inner surface of the mounting cavity 153; the third sealing member 30 covers the second surface of the atomizer core 16, and the portion of the third sealing member 30 corresponding to the second surface of the atomizer core 16 is embedded in the connection portion 45, and together with the sealing assembly 40, is fitted with the inner surface of the accommodating cavity 111 to completely separate the atomizer core 16 from the housing 10.

[0092] It can be understood that the annular side wall 42 of the sealing assembly 40 includes a first side wall 424 and a second side wall 425 that are arranged opposite to each other. The third sealing member 30 only exposes the first surface of the atomizer core 16 to the airflow channel except for the part that is arranged in contact with the inner surface of the mounting cavity 153. Through holes 423 are provided on both the first side wall 424 and the second side wall 425, and part of the side wall of the third sealing member 30 is embedded in the through hole 423 on the first side wall 424, so that the third sealing member 30 cooperates with the sealing assembly 40 to isolate the second surface of the atomizer core 16 from the inner surface of the receiving cavity 111; that is, the side wall of the third sealing member 30 cooperates with the first side wall 424 to expose the first surface of the atomizer core 16 to the airflow channel, so that the first surface of the atomizer core 16 and the inner surface of the receiving cavity 111 form an airway connecting the connecting hole 1513 and the air inlet 1521; the second surface is completely isolated from the inner surface of the receiving cavity 111. In other words, only one side of the atomizer core 16 allows airflow to pass. It can be understood that in order to reduce the thickness of the atomizer 1, the first side wall 424 embedded in the side wall of the third sealing member 30 can be arranged to fit the inner surface of the accommodating cavity 111, that is, the first side wall 424 of the sealing assembly 40 and the third sealing member 30 are arranged to fit the inner surface of the accommodating cavity 111; because the side wall of the third sealing member 30 cooperates with the first side wall 424 of the sealing assembly 40 to completely isolate the atomizer core 16 from the inner surface of the accommodating cavity 111, the heat generated by the heating of the atomizer core 16 can be effectively isolated, and high-temperature deformation of the shell 10 can be avoided.

[0093] Alternatively, only the through hole 423 is provided on the first side wall 424, so that an air passage connecting the connecting hole 1513 and the air inlet 1521 is formed only between the first surface of the atomizer core 16 and the inner surface of the accommodating cavity 111; that is, only one side of the atomizer core 16 can allow airflow to pass. It can be understood that in this embodiment, the third sealing member 30 can make the first surface and the second surface of the atomizer core 16 completely exposed except for the part that fits with the inner surface of the mounting cavity 153, or only the first surface of the atomizer core 16 can be completely exposed except for the part that fits with the inner surface of the mounting cavity 153; if the third sealing member 30 is selected to expose only the first surface of the atomizer core 16, the thickness of the atomizer 1 is thicker than when the third sealing member 30 exposes both the first surface and the second surface of the atomizer core 16. In this embodiment, since only one side of the atomizer core 16 allows airflow to pass through, in order to reduce the thickness of the atomizer 1, the second side wall 425 of the sealing assembly 40 can be arranged to fit the inner surface of the accommodating cavity 111; at the same time, the second side wall 425 completely isolates the atomizer core 16 from the cavity wall of the accommodating cavity 111, which can effectively isolate the heat generated by the atomizer core 16 and avoid high-temperature deformation of the shell 10.

[0094] In another embodiment, the connecting portion 45 allows at least one section of the first surface and the second surface of the atomizer core 16 to be exposed to the air flow channel. Further, the third sealing member 30 allows the first surface portion and the second surface portion of the atomizer core 16 to be fitted with the inner surface of the mounting cavity, and allows the first surface and the second surface, except for the portion fitted with the inner surface of the mounting cavity 153, to be completely exposed to the air flow channel.

[0095] It is understood that through holes 423 are provided on the first side wall 424 and the second side wall 425, so that the first surface and the second surface of the atomizer core 16 are at least partially exposed, and the first surface and the second surface of the atomizer core 16 form an airway connecting the connecting hole 1513 and the air inlet 1521 with the inner surface of the accommodating cavity 111; that is, both sides of the atomizer core 16 can allow airflow to pass. It is understood that in this embodiment, the third sealing member 30 makes the first surface and the second surface of the atomizer core 16 completely exposed to the airflow channel except for the part that is arranged in contact with the inner surface of the mounting cavity 153. The structural dimensions of the through hole 423 on the first side wall 424 and the structural dimensions of the through hole 423 on the second side wall 425 can be the same or different, and can be designed according to needs, and it is only necessary to expose the first surface and the second surface of the atomizer core 16.

[0096] In the first and second embodiments of the atomizer 1, optionally, the heating element in the atomizer core 16 is arranged on the side of the porous member away from the first lower liquid channel 1511 and the second lower liquid channel 1512; that is, the side of the atomizer core 16 away from the first lower liquid channel 1511 and the second lower liquid channel 1512 is the atomization surface. In another embodiment, the heating element in the atomizer core 16 is arranged on the side of the porous member close to the first lower liquid channel 1511 and the second lower liquid channel 1512; that is, the side of the atomizer core 16 close to the first lower liquid channel 1511 and the second lower liquid channel 1512 is the atomization surface. The position of the atomization surface on the atomizer core 16 is different, and the setting method of the electrode connected to the atomizer core 16 is changed accordingly. Regardless of how the atomization surface of the atomizer core 16 is set, the specific structure of the atomizer 1 is as described above. The materials of the first seal 18, the second seal 19 and the third seal 30 are silicone, plastic, etc., which can achieve sealing.

[0097] See also Fig.14 , Fig.14 It is a schematic diagram of the structure of the battery assembly provided in this application.

[0098] The battery assembly 2 further includes a bracket 21, an electrode contact 22, a first circuit board 23, a battery 24, a second circuit board 25 and an interface 26. The electrode contact 22, the first circuit board 23, the battery 24, the second circuit board 25 and the interface 26 are arranged on the bracket 21, and are assembled together with the bracket 21 in the empty installation space 200 formed by the battery assembly housing 20. Among them, the interface 26 can be any one or a combination of common external interfaces such as a USB interface, a Type-C interface, and a Lightning interface.

[0099] A connection seat 211 is formed at the end of the bracket 21, and the connection seat 211 is used to connect the battery assembly 2 to the atomizer 1. The battery assembly 2 and the atomizer 1 can be connected by magnetic attraction or by snap-on connection, and the specific connection method is designed according to needs. The first circuit board 23 is arranged on the side of the connection seat 211 away from the atomizer 1, the battery 24 is arranged on the side of the first circuit board 23 away from the connection seat 211, and the second circuit board 25 is arranged on the side of the battery 24 away from the first circuit board 23. The first circuit board 23 and the second circuit board 25 are both electrically connected to the battery 24, and the interface 26 is electrically connected to the second circuit board 25. The first circuit board 23 can control the battery 24 to supply power to the atomizer 1; the battery 24 can be charged through the interface 26, and the second circuit board 25 can control when the interface 26 stops inputting current to the battery 24.

[0100] See also Fig.15 , Fig.15 It is a schematic diagram of the partial structure of the battery assembly provided in this application.

[0101] The electrode contact 22 penetrates the connection base 211; both ends of the electrode contact 22 are exposed, one end is exposed to the side of the connection base 211 close to the atomizer 1, and the other end is exposed to the side of the connection base 211 away from the atomizer 1. One end of the electrode contact 22 is connected to the atomizer 1, and the other end is connected to the first circuit board 23, and the first circuit board 23 is electrically connected to the battery 24; the electrode contact 22 is used to realize the electrical connection between the atomizer 1 and the battery 24, and the first circuit board 23 controls the battery 24 to supply power to the atomizer 1.

[0102] A first groove 231 is provided at one end of the first circuit board 23 near the connection seat 211, and part of the electrode contact 22 is accommodated in the first groove 231, and the end of the electrode contact 22 is electrically connected to the first conductive member on the first circuit board 23. By providing the first groove 231 on the first circuit board 23, and part of the electrode contact 22 is provided in the first groove 231, the length of the battery assembly 2 is shortened, and the length of the electronic atomization device is shortened; at the same time, the air-avoiding area on the first circuit board 23 is reduced, and the utilization rate of the first circuit board 23 is improved. The electrode contact 22 is electrically connected through the first conductive member on the bottom wall of the first groove 231, and then realizes electrical connection with the first circuit board 23, reducing the welding wire between the electrode contact 22 and the first circuit board 23, and reducing the cost.

[0103] In one embodiment, one end of the first circuit board 23 close to the connection seat 211 is in contact with the connection seat 211. By setting the one end of the first circuit board 23 close to the connection seat 211 to be in contact with the connection seat 211, the portion of the electrode contact 22 exposed to the side of the connection seat 211 away from the atomizer 1 is completely accommodated in the first groove 231, the size of the battery assembly 2 in the length direction is reduced as much as possible, the air-avoiding area of ​​the first circuit board 23 is reduced to the maximum extent, and the utilization rate of the first circuit board 23 is improved.

[0104] In one embodiment, the electrode contact 22 is a pogo pin (also called a Pogo pin); optionally, the electrode contact 22 is a split pogo pin. The end of the electrode contact 22 away from the first circuit board 23 is retractable, and the end of the electrode contact 22 close to the first circuit board 23 is welded to the first conductive member on the bottom wall of the first groove 231 to achieve electrical connection between the electrode contact 22 and the first circuit board 23. That is, when the end of the electrode contact 22 away from the first circuit board 23 moves, the end of the electrode contact 22 close to the first circuit board 23 does not move.

[0105] See also Fig.16 , Fig.17 and Fig.18 , Fig.16 is another partial structural schematic diagram of the battery assembly provided by the present application, Fig.17 is a partial cross-sectional schematic diagram of a battery assembly provided in the present application, Fig.18 It is a schematic diagram of the structure of the battery provided in this application.

[0106] The battery 24 includes a battery cell 241, a positive electrode ear 242 and a negative electrode ear 243. The battery cell 241 includes a battery cell body 2411 and a battery cell seal 2412, and the battery cell seal 2412 is a sheet structure and has a thickness less than the thickness of the battery cell body 2411. The second circuit board 25 is at least partially stacked with the battery cell seal 2412 to achieve electrical connection between the positive electrode ear 242 and the negative electrode ear 243 and the second circuit board 25. It can be understood that the positive electrode ear 242 and the negative electrode ear 243 are arranged on the surface where the battery cell seal 2412 contacts the second circuit board 25. By making the second circuit board 25 at least partially stacked with the battery cell seal 2412, the size of the battery assembly 2 in the length direction is shortened; at the same time, the space in the thickness direction of the battery cell seal 2412 is fully utilized, and the thickness of the battery assembly 2 is further thinned, making the electronic atomization device thinner and lighter.

[0107] In one embodiment, the battery cell seal 2412 includes a first surface and a second surface relative to each other, the first surface of the battery cell seal 2412 is flush with a surface in the thickness direction of the battery cell body 2411, and the positive electrode ear 242 and the negative electrode ear 243 are arranged on the second surface of the battery cell seal 2412. The second circuit board 25 is stacked with the second surface of the battery cell seal 2412. The thickness of the second circuit board 25 is less than the distance between the second surface of the battery cell seal 2412 and the other surface of the battery cell body 2411. By setting the first surface of the battery cell seal 2412 to be flush with a surface in the thickness direction of the battery cell body 2411, after the second circuit board 25 is stacked with the second surface of the battery cell seal 2412, the size of the battery assembly 2 in the thickness direction is minimized, thereby reducing the thickness of the electronic atomization device.

[0108] Specifically, the surface of the second circuit board 25 in contact with the cell seal 2412 is provided with a second conductive member, and the positive electrode ear 242 and the negative electrode ear 243 cooperate with the second conductive member to realize the electrical connection between the cell 241 and the second circuit board 25. Optionally, the positive electrode ear 242 and the negative electrode ear 243 are in contact with the second conductive member to realize the electrical connection between the cell 241 and the second circuit board 25; optionally, the positive electrode ear 242 and the negative electrode ear 243 are welded to the second conductive member to realize the electrical connection between the cell 241 and the second circuit board 25. It can be understood that the setting position of the second conductive member on the second circuit board 25 corresponds to the setting of the positive electrode ear 242 and the negative electrode ear 243. Through the above setting, the welding wire between the positive electrode ear 242 and the negative electrode ear 243 and the second circuit board 25 is reduced, which is conducive to saving material costs and reducing assembly costs.

[0109] In one embodiment, the second circuit board 25 is in contact with the battery cell body 2411 on one side thereof, thereby minimizing the length dimension of the battery assembly 2 and making the electronic atomization device thinner and lighter.

[0110] A second groove 251 is provided at one end of the second circuit board 25 away from the battery cell 241 , and the interface 26 is embedded in the second groove 251 , which reduces the length dimension of the battery assembly 2 , reduces the air-avoidance area of ​​the second circuit board 25 , and improves the utilization rate of the second circuit board 25 .

[0111] The atomizer of the present application includes an atomizer seat, an atomizer core and a seal; the atomizer seat includes an atomizer top seat and an atomizer base, and the atomizer top seat and the atomizer base cooperate to form an installation cavity; the atomizer core is arranged in the installation cavity; the seal is arranged between the atomizer core and the atomizer top seat, and in the height direction of the atomizer core, the seal exposes at least one side of the atomizer core to the air flow channel. Through the above arrangement, the atomizer is thinned in the thickness direction without affecting the heating efficiency of the atomizer core, and the atomized aerosol has a better taste.
