[0039] In the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details that hinder the description of the present invention.

[0040] The present application provides an electronic atomization device, which can be used for atomization of an aerosol-generating substrate. The electronic atomization device includes an atomizer and an electric control module which are electrically connected to each other.

[0041] The atomizer is used to store the aerosol-generating matrix, and heat and atomize the aerosol-generating matrix to form an aerosol that can be inhaled / inhaled by the user. The atomizer can be used in different fields, such as medical treatment, beauty, leisure inhalation, etc. The aerosol-generating matrix is ​​a fluid, which can be a liquid or a gas. The atomizer of the present application is described below by taking the aerosol generated by the atomizer for the user to inhale as an example.

[0042] The atomizer may include a liquid storage chamber (not shown) for storing an aerosol-generating substrate, and an atomizing core 1 (see Figure 1 ); The aerosol-generating substrate in the liquid storage chamber can flow to the atomizing core 1, and the aerosol-generating substrate is heated by the atomizing core 1. Figure 2 An air flow channel 11 is formed in the atomizing core 1, and external air can flow into the atomizing core 1 from one end (the air inlet end 111) and flow out from the other end (the air outlet end 112) of the atomizing core 1 to bring out the aerosol-generating matrix.

[0043] The electric control module (not shown) may include a battery and a controller. The battery is used to provide power for the atomizer; the controller is used to control the atomizer. The specific structure and control method of the controller can refer to the relevant technology and will not be described here. The electric control module may also include other components such as a battery holder and an airflow sensor, which will not be described here.

[0044] In some embodiments, see Figure 2 , the atomizer core 1 may include an outer tube 12, a conduction component 14 and an atomizer component 13. The outer tube 12 may be disposed in a liquid storage cavity, and the outer tube 12 may be provided with at least one fluid inlet 121 in communication with the liquid storage cavity; the aerosol generating substrate may enter the outer tube 12 through the fluid inlet 121; of course, the fluid inlet 121 does not necessarily need to be formed on the outer tube 12, and may be provided on other structures of the atomizer core 1. In other words, the outer tube 12 is not a necessary component of the atomizer core 1, as long as the aerosol generating substrate can enter the interior of the atomizer core 1. The conduction component 14 is used to store and conduct the aerosol generating substrate, and it may conduct the aerosol generating substrate to the atomizer component 13. The atomizer component 13 may absorb the aerosol generating substrate, and heat and atomize the aerosol generating substrate.

[0045] like Figure 2 As shown, the atomization component 13 may include a mounting component 131 and a heating component 132 mounted on the mounting component 131 . The mounting component 131 may conduct the aerosol generating substrate conducted by the conducting component 14 to the heating component 132 , and the heating component 132 heats the aerosol generating substrate.

[0046] Looking at the structure of the conductive component 14 , the conductive component 14 may include a first conductive member 141 and a second conductive member 142 .

[0047] The first conductive member 141 can be used to store and conduct the aerosol generating matrix, and is fluidly connected to the mounting member 131. In addition, the first conductive member 141 is closer to the fluid inlet port 121 than the second conductive member 142. The aerosol generating matrix entering from the fluid inlet port 121 will first flow through the first conductive member 141, so as to guide the aerosol generating matrix in the liquid storage tank to the mounting member 131. This fluid connection can be understood as fluid transmission being able to be performed between them.

[0048] The second conductive member 142 can also be used to store and conduct the aerosol generating matrix and is connected to the fluid of the mounting member 131. However, a limiting portion 143 is provided between the second conductive member 142 and the first conductive member 141 so that the fluid conduction capacity between the first conductive member 141 and the second conductive member 142 can be worse than the fluid conduction capacity between the mounting member 131 and the first conductive member 141.

[0049] It can be understood that the above fluid conduction capacity is used to reflect the difficulty of fluid conduction between the first conduction member 141 and the second conduction member 142, and between the mounting member 131 and the first conduction member 141; the present application affects the fluid conduction capacity between the first conduction member 141 and the second conduction member 142 through the design of the limiting portion 143, so that the fluid conduction capacity between the first conduction member 141 and the second conduction member 142 can be worse than the fluid conduction capacity between the mounting member 131 and the first conduction member 141; at the same time, it should be noted that, unlike the conduction efficiency, the fluid conduction capacity is only used to indicate the performance at the structural level, and does not consider the influence of external factors on it. The influence of external factors, for example, the conduction efficiency deteriorates due to the absorption of aerosol to generate a matrix to saturation.

[0050] In order to ensure the taste, the electronic atomization device in the related art usually chooses to set a ventilation channel connecting the liquid storage cavity and the outside world to speed up the liquid flow rate of the liquid storage cavity. However, since the storage capacity of the conductive part is limited, when the liquid flow rate of the liquid storage cavity is too fast, the conductive part is easily saturated, and the aerosol generating matrix on it will be squeezed to the mounting part 131, causing the aerosol generating matrix absorbed by the mounting part 131 to be too saturated, thereby causing leakage. Especially when the electronic atomization device is left for a long time, leakage is more likely to occur.

[0051] In the present application, since the electronic atomization device is provided with a first conductive member 141 and a second conductive member 142, wherein the first conductive member 141 is used to guide the aerosol generating matrix in the liquid storage tank to the mounting member 131; and the aerosol generating matrix in the liquid storage tank will not be easily conducted to the second conductive member 142 due to the existence of the limiting part 143. When the efficiency of the heating element 132 in consuming the aerosol generating matrix is ​​equivalent to the efficiency of the first conductive member 141 in conducting the aerosol generating matrix to the mounting member 131, the aerosol generating matrix will not be conducted to the second conductive member 142, or the amount conducted to the second conductive member 142 will be very small; and when the aerosol generating matrix at the mounting member 131 is saturated and is about to leak, the aerosol generating matrix will be actively conducted to the second conductive member 142, and the second conductive member 142 can absorb part of the aerosol generating matrix on the mounting member 131 and / or the first conductive member 141, thereby solving the problem of leakage.

[0052] The following is a detailed description of the specific structure and connection relationship of the atomizer core 1 in some embodiments. Figure 2 , the side of the structure close to the air inlet end 111 of the atomizer core 1 is called the bottom / bottom end, and the side of the structure away from the air inlet end 111 of the atomizer core 1 is called the top / top end.

[0053] Example 1

[0054] See also Figure 2 The outer tube 12 may be cylindrical; of course, the outer tube 12 may also be in other shapes, such as a square tube, which is not limited here. A plurality of fluid inlet ports 121 are provided on the circumference of the outer tube 12 .

[0055] like Figure 2 As shown, the mounting member 131 includes a liquid absorption surface and an atomization surface opposite to the liquid absorption surface; the liquid absorption surface is used to be fluidly connected with the first conductive member 141 and the second conductive member 142 to conduct the aerosol generating matrix; the aerosol generating matrix on the liquid absorption surface can be conducted to the atomization surface, and the atomization surface is used to be connected to the heating element 132, and the heating element 132 heats the aerosol generating matrix conducted to the atomization surface.

[0056] Optionally, the mounting member 131 may be cylindrical, with its outer surface serving as a liquid absorbing surface and its inner surface serving as an atomizing surface.

[0057] The heating element 132 may include one or more heating circuits, and electrode portions respectively arranged on both sides of each heating circuit along the length direction thereof. The heating circuit is a sheet structure, which is arranged to be curled and attached to the inner circumferential side of the mounting member 131; when multiple heating circuits are arranged, the multiple heating circuits can be arranged at intervals along the axial direction of the mounting member 131. The electrode portion is used to connect to a power source.

[0058] See also Figure 3 The atomizing assembly 13 may further include a cylindrical mounting seat 133 for providing a foundation for connecting the mounting member 131 with the first conductive member 141 and the second conductive member 142. The mounting seat 133 may be sleeved on the outer periphery of the mounting member 131; Figure 4 The mounting seat 133 is also provided with a first liquid transfer port 1331 and a second liquid transfer port 1332 which are through and arranged in an axially spaced manner; Figure 5 The first liquid transfer port 1331 is disposed between the first conductive member 141 and the mounting member 131 to connect the first conductive member 141 and the mounting member 131 fluidly, and the second liquid transfer port 1332 is disposed between the second conductive member 142 and the mounting member 131 to connect the second conductive member 142 and the mounting member 131 fluidly.

[0059] Optionally, a plurality of first liquid transfer ports 1331 may be provided, arranged on the circumference of the mounting seat 133. Similarly, a plurality of second liquid transfer ports 1332 may also be provided, arranged on the circumference of the mounting seat 133.

[0060] The first conductive member 141 and the second conductive member 142 are made of a capillary material, which is a material that can achieve fluid conduction. Optionally, the capillary material can be a capillary material; the capillary material can be a porous material; for example, the first conductive member 141 and the second conductive member 142 are porous ceramics. Of course, the capillary material can also be a sponge-like, fibrous or foam-like material; for example, the first conductive member 141 and the second conductive member 142 are liquid-conducting cotton.

[0061] The mounting member 131, the first conductive member 141, and the second conductive member 142 can be made of the same material or different materials, and there is no specific limitation here, as long as fluid circulation can be achieved. Similarly, the pore size and porosity of the mounting member 131, the first conductive member 141, and the second conductive member 142 are not limited, as long as fluid circulation can be achieved.

[0062] Can be reviewed Figure 2 The first conductive member 141 may be cylindrical and installed in the outer tube 12. The outer diameter of the first conductive member 141 may be equal to the inner diameter of the outer tube 12, so that the outer peripheral side of the first conductive member 141 may contact the inner peripheral side of the outer tube 12. The outer surface of the first conductive member 141 may be at least partially opposite to the orifice of the fluid inlet port 121 in the radial direction of the outer tube 12 to facilitate liquid supply.

[0063] Similarly, the second conductive member 142 can be cylindrical and installed in the outer tube 12, and the second conductive member 142 is closer to the air outlet end 112 of the air flow channel 11 than the first conductive member 141; the outer diameter of the second conductive member 142 can be equivalent to the inner diameter of the outer tube 12, so that the outer peripheral side surface of the second conductive member 142 can contact the inner peripheral side surface of the outer tube 12.

[0064] like Figure 3 As shown, the first conductive member 141 can be arranged to be in fluid communication with the bottom end of the mounting member 131. Optionally, the inner diameter of the first conductive member 141 can be equivalent to the outer diameter of the mounting member 131, and the first conductive member 141 can be sleeved on the outer peripheral side of the mounting member 131, so that the inner peripheral side surface of the first conductive member 141 can contact the outer peripheral side surface of the mounting member 131; during assembly, the first conductive member 141 and the mounting member 131 are respectively tightly attached to the inner and outer side surfaces of the mounting seat 133 to ensure that the space between the first liquid transmission port 1331 and the first conductive member 141 and the mounting member 131 is sealed to avoid leakage. Optionally, the first conductive member 141 is inserted into the mounting member 131 from the bottom end of the mounting member 131; the outer peripheral side surface of the first conductive member 141 contacts the inner peripheral side surface of the mounting member 131.

[0065] Similarly, the second conductive member 142 can be arranged to be in fluid communication with the top end of the mounting member 131; the inner diameter of the second conductive member 142 can be equal to the outer diameter of the mounting member 131, so that the inner circumferential side surface of the second conductive member 142 can contact the outer circumferential side surface of the mounting member 131. During assembly, the second conductive member 142 and the mounting member 131 are respectively attached to the inner and outer circumferential side surfaces of the mounting seat 133 to ensure that the space between the second liquid transmission port 1332 and the second conductive member 142 and the mounting member 131 is sealed to avoid leakage. Alternatively, the second conductive member 142 is inserted into the mounting member 131 from the top end of the mounting member 131; the outer circumferential side surface of the second conductive member 142 contacts the inner circumferential side surface of the mounting member 131.

[0066] In Example 1, the second conductive member 142 and the first conductive member 141 are arranged at intervals in the axial direction of the mounting member 131, and there is an empty area 1431 between the two; the empty area 1431 serves as a limiting portion 143, so that the fluid conduction capacity between the first conductive member 141 and the second conductive member 142 is zero, and the aerosol generating substrate in the first external liquid storage tank needs to pass through the first conductive member 141 and the mounting member 131 in sequence to reach the second conductive member 142. Therefore, when the aerosol generating substrate at the mounting member 131 is saturated and is about to leak, the second conductive member 142 can absorb the oversaturated aerosol generating substrate at the mounting member 131, thereby solving the problem of leakage caused by saturation of the aerosol generating substrate at the mounting member 131.

[0067] Continue to refer Figure 3As shown, the first conductive member 141, the second conductive member 142 and the mounting member 131 can define a flow channel 113 together, and the flow channel 113 can be used as a part of the airflow channel 11. The second conductive member 142 is arranged at a downstream position of the flow channel 113 in the airflow direction, and the first conductive member 141 is arranged at an upstream position of the flow channel 113 in the airflow direction.

[0068] It should be noted here that after the airflow passes through the atomization component 13 to form an aerosol, the aerosol will flow along the inner circumference of the second conductive member 142 toward the air outlet end 112; during the flow process, part of the aerosol may become condensed liquid due to the lower temperature. At this time, since the second conductive member 142 is arranged at the downstream position of the airflow direction of the flow channel 113, the second conductive member 142 can absorb the condensed liquid; this allows the second conductive member 142 to transfer the absorbed aerosol generating matrix (including the aerosol generating matrix overflowing from the absorbing mounting member 131, and the condensed liquid) to the mounting member 131 when the wetness of the mounting member 131 is less than that of the second conductive member 142 (for example, when the aerosol generating matrix in the liquid storage chamber is insufficient) to the second conductive member 142. When the amount of liquid stored in the liquid storage chamber is constant, the use time of the electronic atomization device can be increased (that is, the number of puffs can be increased). In addition, the condensed liquid can be prevented from affecting the user's taste when puffing. See also Figure 2 The atomizer core 1 may further include a base 15, which is installed in the outer tube 12 and blocks the bottom opening of the shell. The base 15 may be a plastic part; during assembly, the base 15 may be installed in the outer tube 12 by riveting. At this time, the first conductive member 141 may be placed on the top of the base 15. The mounting frame may be inserted into the base 15 to fix the mounting frame in the outer tube 12.

[0069] The base 15 may be a cylindrical structure, and its maximum outer diameter may be equivalent to the inner diameter of the outer tube 12, and is used to seal the inner peripheral edge of the outer tube 12; at the same time, the inner periphery of the base 15 may connect the inside and the outside of the outer shell, and the airflow may pass through the inside of the base 15 and flow to the first conductive member 141.

[0070] Continue to see Figure 2 The atomizer core 1 may further include a sealing ring 16, which is installed in the outer tube 12 and blocks the top opening of the outer shell. During assembly, after the second conductive member 142 is installed in the outer tube 12, the sealing ring 16 is used to press the second conductive member 142 down to face the second liquid transfer port 1332 of the mounting seat 133; after assembly, the top of the second conductive member 142 abuts against the sealing ring 16.

[0071] The sealing ring 16 can be a cylindrical structure, and can be selected as a silicone member, for sealing the inner peripheral edge of the outer tube 12; at the same time, a central channel 161 is provided in the sealing ring 16, which can connect the inside and outside of the shell, and the air flow can pass through the inside of the sealing ring 16 and flow out to the outside of the shell.

[0072] Example 2

[0073] See also Figure 6 The atomizer core 1 of this embodiment is modified on the basis of the embodiment 1. The main modification is the change of the restriction portion 143. The following describes the structures of the atomizer core 1 of the embodiment 2 that are different from those of the embodiment 1. The other structures of the atomizer core 1 not mentioned can refer to the embodiment 1 and will not be described here.

[0074] In Example 2, the limiting portion 143 includes a first connecting portion 1432 for conducting an aerosol generating matrix, which is connected between the first conductive member 141 and the second conductive member 142; the limiting portion 143 also includes a recess 1433 formed on or around the first connecting portion 1432 to reduce the fluid conduction capacity between the first conductive member 141 and the second conductive member 142.

[0075] It can be understood that the recess 1433 is used to reduce the fluid conduction area between the first conductive member 141 and the second conductive member 142 , thereby achieving the purpose of reducing the fluid conduction capacity between the first conductive member 141 and the second conductive member 142 .

[0076] The first connection part 1432 may be cylindrical, and its outer diameter is smaller than the outer diameters of the first conductive member 141 and the second conductive member 142, and the recess 1433 is formed at the outer peripheral side of the first connection part 1432. Of course, the formation method of the recess 1433 is not specifically limited here. Alternatively, the first connection part 1432 is cylindrical, and its inner diameter is larger than the inner diameters of the first conductive member 141 and the second conductive member 142, and the recess 1433 is formed at the inner peripheral side of the first connection part 1432, between the first connection part 1432 and the mounting member 131. Alternatively, the recess 1433 is formed by slotting the first connection part 1432.

[0077] As for the fluid conductivity of the first connecting part 1432 itself (such as porosity), the size of the recess 1433 and the number of recesses 1433, they can be set according to product requirements, as long as the fluid conductivity between the first conductive member 141 and the second conductive member 142 is lower than the fluid conductivity between the mounting member 131 and the first conductive member 141.

[0078] Example 3

[0079] See also Figure 7The atomizer core 1 of this embodiment is modified on the basis of the embodiment 1. The main modification is the change of the restriction portion 143. The following describes the structures of the atomizer core 1 of the embodiment 3 that are different from those of the embodiment 1. The other structures of the atomizer core 1 not mentioned can refer to the embodiment 1 and will not be described here.

[0080] In Embodiment 3, the restricting portion 143 includes a second connecting portion 1434 connected between the first conductive member 141 and the second conductive member 142 .

[0081] The second connecting portion 1434 can be a capillary structure, that is, it is made of a capillary material, or is a structure manufactured with a capillary; the porosity of the second connecting portion 1434 is greater than zero and is less than the porosity of the mounting member 131 and the first conductive member 141, so that the aerosol generating matrix on the first conductive member 141 is preferentially transferred to the mounting member 131.

[0082] The second connecting portion 1434 may also be a closed structure, that is, the porosity thereof is zero, and only the aerosol generating matrix on the mounting member 131 can be conducted to the second conducting member 142 .

[0083] Secondly, the second connection portion 1434 may be cylindrical, and its outer diameter may be comparable to the outer diameters of the first conductive member 141 and the second conductive member 142 ; of course, the size may be adjusted according to actual needs, and is not specifically limited here.

[0084] In summary, the atomizer core of the present application is designed with a first conductive member 141, a second conductive member 142 and a limiting portion 143 between the first conductive member 141 and the second conductive member 142. Under normal circumstances, the first conductive member 141 is used to conduct the aerosol generating matrix entering from the fluid inlet 121 to the mounting member 131, and when the mounting member 131 is saturated, the second conductive member 142 is used to absorb the excess aerosol generating matrix due to saturation, thereby effectively alleviating / solving the problem of liquid leakage caused by the saturation of the mounting member 131.

[0085] Secondly, the second conductive member 142 can also generate a matrix by recovering condensed liquid and absorbing the aerosol overflowing from the mounting member 131, thereby extending the use time.

[0086] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should belong to the scope covered by the claims of the utility model.
