For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0050] 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.

[0051] The present application provides an electronic atomization device, which can be used for atomization of an aerosol-generating substrate. Figure 1 The electronic atomization device may include an atomizer 100 and an electronic control component 200 which are electrically connected to each other.

[0052] The atomizer 100 is used to store a liquid aerosol-generating substrate, and heat and atomize the aerosol-generating substrate to form an aerosol that can be inhaled / inhaled by a user. The atomizer 100 can be used in different fields, such as medical treatment, beauty, leisure inhalation, etc. The atomizer 100 of the present application is described below by taking the aerosol generated by the atomizer 100 for inhalation by a user as an example.

[0053] like Figure 1As shown, the atomizer 100 may include a liquid storage chamber 1 for storing a liquid aerosol-generating substrate, and an atomizing core 2 disposed in the liquid storage chamber 1; a liquid flow channel may be formed between the liquid storage chamber 1 and the atomizing core 2, so that the aerosol-generating substrate in the liquid storage chamber 1 may flow to the atomizing core 2, and the aerosol-generating substrate is heated by the atomizing core 2. At the same time, an air flow channel 3 is formed in the electronic atomization device, and external air may flow in from one end of the air flow channel 3 (the air inlet end 31), and flow out from the other end of the air flow channel 3 (the air outlet end 32), so as to carry out the atomized aerosol-generating substrate.

[0054] In some embodiments, see Figure 2 , the atomizer core 2 may include an outer tube 21, a liquid storage part 22 and an atomizer assembly 23. Among them, the outer tube 21 may be arranged in the liquid storage chamber 1, and the outer tube 21 is provided with at least one first liquid inlet hole 211 which is in liquid communication with the liquid storage chamber 1; the liquid communication may be understood as being able to pass liquid. The liquid storage part 22 may be arranged in the outer tube 21, for absorbing the aerosol generating matrix flowing in from the first liquid inlet hole 211, and conducting it to the atomizer assembly 23; and, the liquid storage part 22 is provided with a central channel 221 for forming part of the air flow channel 3. The atomizer assembly 23 may be arranged at the central channel 221 of the liquid storage part 22, for absorbing the aerosol generating matrix conducted through the liquid storage part 22, and heating and atomizing the aerosol generating matrix.

[0055] Secondly, the present application designs that the liquid storage chamber 1 is connected to the outside world by an air path, which is used to balance the pressure difference between the liquid storage chamber 1 and the outside world during the suction process, so as to ensure that the atomizer assembly 23 is in a sufficient state to absorb the aerosol generating matrix during the suction process. The sufficient state can be understood as the amount of the aerosol generating matrix on the atomizer assembly 23 can produce an aerosol with a preset concentration or greater than the preset concentration; the preset concentration described here can be adjusted according to actual needs. When the amount of the aerosol generating matrix on the atomizer assembly 23 is insufficient, continuing to heat it will affect the aerosol concentration and taste, and may even cause dry burning. Secondly, because the liquid storage chamber 1 is generally a closed space, the pressure of the liquid storage chamber 1 will gradually decrease during the liquid discharge process, and the pressure difference between the inside and outside of the liquid storage chamber 1 will gradually increase, resulting in a decrease in the amount of liquid discharged from the aerosol generating matrix in the liquid storage chamber 1, which in turn leads to insufficient aerosol generating matrix on the atomizer assembly 23. If the atomizer assembly 23 can maintain a sufficient state of absorbing the aerosol generating matrix, the above-mentioned problem of insufficient aerosol concentration and attenuation of the taste of long draw can be solved.

[0056] Optionally, the air path formed between the liquid storage chamber 1 and the outside world can be formed in the atomizer core 2, and the first liquid inlet hole 211 is connected to the air flow channel 3 to achieve the purpose of ventilation. Figure 3One or more first air channels 4 are provided in the atomizer core 2, which connect the first liquid inlet hole 211 and the central channel 221 of the liquid storage member 22 in a ventilated manner; the ventilated connection can be understood as being able to pass gas.

[0057] Alternatively, the air path formed between the liquid storage chamber 1 and the outside world can be arranged at the liquid storage chamber 1, directly connecting the liquid storage chamber 1 with the outside world to achieve the purpose of ventilation. Fig.13 The electronic atomization device includes an injection hole 61 connected to the liquid storage chamber 1, and an injection plug 62 for blocking the injection hole 61; the aerosol generating matrix can be injected / replenished from the outside into the liquid storage chamber 1 through the injection hole 61; one or more second air channels 63 are provided on the injection plug 62, which directly connect the liquid storage chamber 1 with the outside in a ventilated manner.

[0058] It should be noted that the first air channel 4 / second air channel 63 is a channel through which gas can flow, but liquid cannot flow; for example, the air channel is a capillary pore. It can be understood that liquid has surface tension. When the diameter of the air channel is less than a certain degree, the liquid cannot enter the air channel due to the surface tension, thereby effectively avoiding the leakage caused by ventilation; as for the specific value of the diameter of the air channel, please refer to the relevant technology, which will not be elaborated here.

[0059] The electric control assembly 200 may include a battery (not shown) and a controller (not shown). The battery is used to provide power for the operation of the atomizer 100; the controller is used to control the operation of the atomizer 100. The specific structure and control method of the controller can refer to the relevant technology and will not be described here. The electric control assembly 200 may also include other components such as a battery holder and an airflow sensor, which will not be described here.

[0060] The following examples illustrate the structure of the atomizer 100 in some embodiments of the present application, and the formation position of the gas path used for ventilation. Figure 3 The side of the structure adjacent to the air outlet end 32 of the atomizer 100 is called the top / top end, and the side of the structure away from the air inlet end 31 of the atomizer core 2 is called the bottom / bottom end.

[0061] Example 1

[0062] For reference Figure 2 and Figure 3 The atomizer 100 includes a liquid storage chamber 1 and an atomizer core 2. The atomizer core 2 includes an outer tube 21, a liquid storage component 22 and an atomizer assembly 23. The matching relationship and functions between them can be found above and will not be repeated here.

[0063] like Figure 2As shown, the outer tube 21 may be cylindrical; of course, the outer tube 21 may also be in other shapes, such as a square tube, which is not limited here. A plurality of first liquid inlet holes 211 are provided on the circumference of the outer tube 21 .

[0064] The liquid storage member 22 may also be cylindrical, defining a central channel 221; of course, the liquid storage member 22 may also be in other shapes, such as a square cylinder, which is not limited here. Figure 3 As shown, the outer diameter of the liquid storage member 22 is equivalent to the inner diameter of the outer tube 21 , and the outer peripheral side surface of the liquid storage member 22 can contact the inner peripheral side surface of the outer tube 21 .

[0065] For reference Figure 2 and Figure 3 The atomizing assembly 23 may include an inner guide 231 and a heating element 232 connected to the inner guide 231. The outer surface of the inner guide 231 may contact the liquid storage element 22 to conduct the aerosol generating substrate; the heating element 232 may be arranged on the inner periphery of the inner guide 231 to heat the aerosol generating substrate on the inner guide 231.

[0066] The axial length of the inner guide member 231 may be smaller than the axial length of the liquid storage member 22. Both axial ends of the inner guide member 231 may be between both axial ends of the liquid storage member 22.

[0067] The inner guide 231 may include a cylindrical main body 2311 and a protrusion 2312 protruding from one side of the main body 2311. The outer diameter of the main body 2311 may be equivalent to the inner diameter of the liquid storage member 22, and the outer peripheral side surface of the main body 2311 may fit the inner peripheral side surface of the liquid storage member 22. The protrusion 2312 may be embedded in the liquid storage member 22, which may effectively improve the stability of the inner guide 231 fixed in the liquid storage member 22 on the one hand, and increase the contact area between the inner guide 231 and the liquid storage member 22 on the other hand, which is beneficial to liquid conduction.

[0068] The heating element 232 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 inner guide 231; when multiple heating circuits are arranged, the multiple heating circuits may be arranged at intervals along the axial direction of the inner guide 231. The electrode portion is used to connect to a power source.

[0069] The atomizing assembly 23 may further include a cylindrical mounting seat 233, which is used to provide a mounting base for the inner guide 231 to be mounted on the liquid storage member 22. The mounting seat 233 may be sleeved on the outer periphery of the inner guide 231, and the inner guide 231 may be fixed in the liquid storage member 22 by embedding the mounting seat 233 in the liquid storage member 22. The mounting seat 233 is also provided with a plurality of liquid guide openings 2331 that penetrate through the periphery thereof, so that the aerosol generating substrate in the liquid storage member 22 is transmitted to the inner guide 231.

[0070] like Figure 3 As shown, the atomizer core 2 may further include a base 24, which is installed in the outer tube 21 and blocks the bottom opening of the outer tube 21. The base 24 may be a plastic part; during assembly, the base 24 may be installed in the outer tube 21 by riveting.

[0071] The base 24 can be a cylindrical structure, and its maximum outer diameter can be equivalent to the inner diameter of the outer tube 21, and is used to seal the inner peripheral edge of the outer tube 21; at the same time, the channel 241 left in the base 24 can connect the central channel 221 of the liquid storage part 22 and the outside of the outer tube 21 to form a partial airflow channel 3.

[0072] The liquid storage member 22 can be placed on the top of the base 24, and the bottom of the liquid storage member 22 can abut against the top of the base 24. The bottom end of the mounting seat 233 can be inserted into the channel 241 of the base 24.

[0073] In this embodiment, reference may be made to Figure 4 The first liquid inlet hole 211 is located on the peripheral side of the base 24, and a liquid storage space 25 is left between the first liquid inlet hole 211 and the base 24. The liquid storage space 25 can make it easier for the aerosol-generating substrate to flow to the liquid storage part 22, thereby shortening the waiting time required for suction. The liquid storage space 25 is located on the side of the liquid storage part 22 facing the base 24; the aerosol-generating substrate can enter from the first liquid inlet hole 211, and reach the liquid storage part 22 after passing through the liquid storage space 25.

[0074] For reference Figure 3 A second air guide groove 242 is also provided on the base 24 , one end of the second air guide groove 242 is connected to the air inlet end 31 , and the other end thereof is ventilatedly connected to the first liquid inlet hole 211 to form a first air channel 4 .

[0075] Optionally, see Figure 5 , Figure 6 The base 24 may include an axially connected first barrel section 243 and a second barrel section 244; the first barrel section 243 is closer to the liquid storage member 22 than the second barrel section 244. The outer diameter of the second barrel section 244 may be equivalent to the inner diameter of the outer tube 21; and the outer diameter of the first barrel section 243 is smaller than the inner diameter of the outer tube 21, so that the above-mentioned liquid storage space 25 is formed between the outer side wall of the first barrel section 243 and the inner side wall of the outer tube 21, and the liquid storage space 25 is annular. The first barrel section 243 may also be arranged opposite to the first liquid inlet hole 211 in the radial direction.

[0076] The second air guide groove 242 may be formed on the second barrel section 244, wherein both ends of the second air guide groove 242 are designed to be open, and the openings at both ends may be respectively arranged on two axial end faces of the second barrel section 244. The airflow may flow into the second air guide groove 242 from the bottom end face of the second barrel section 244, and flow out from the end face of the second barrel section 244, and sequentially pass through the liquid storage space 25 and the first liquid inlet hole 211 to reach the liquid storage chamber 1, thereby achieving ventilation.

[0077] Preferably, the openings at both ends of the second air guide groove 242 can be arranged at opposite sides of the circumference of the base 24; the second air guide groove 242 is also provided with a connecting groove section 2421 for connecting the openings at both ends, and the connecting groove section 2421 is arranged on the outer circumference of the second barrel section 244 and extends along the circumference of the second barrel section 244. This design can effectively prevent leakage, and even if the aerosol generating substrate flows into the second air guide groove 242 by mistake, it will only remain at the connecting groove section 2421 of the second air guide groove 242 and will not easily flow out from the bottom end surface of the second barrel section 244. Optionally, the connecting groove section 2421 is in a circular shape, and its center is located on the central axis of the base 24.

[0078] Example 2

[0079] See also Figure 7 The atomizer 100 of this embodiment is modified on the basis of the embodiment 1. The main modifications are the formation position of the first air channel 4 and the relative position of the first liquid inlet hole 211; the following describes the structures of the atomizer 100 of the embodiment 2 that are different from those of the embodiment 1. The other structures of the atomizer 100 not mentioned can refer to the embodiment 1 and will not be described here.

[0080] In this embodiment, if Figure 7 As shown, the first liquid inlet 211 is located on the outer peripheral side of the liquid storage member 22, and is relatively located on the side of the base 24 facing the liquid storage member 22. The base 24 is a cylindrical structure, and its outer peripheral side wall is in contact with the inner peripheral side wall of the outer tube 21, which can play a sealing role.

[0081] like Figure 7 As shown, at least one first air guide groove 222 is provided on the liquid storage part 22 to form a first air channel 4; the first air guide groove 222 is connected to the central channel 221 of the liquid storage part 22 through the pore structure on the liquid storage part 22; and at least one first air guide groove 222 and at least one first liquid inlet hole 211 are arranged opposite to each other in the radial direction of the outer tube 21. It can be understood that the airflow entering from the air inlet end 31 can pass through the central channel 221 of the liquid storage part 22, the pore structure of the liquid storage part 22, the first air guide groove 222, the first liquid inlet hole 211, and the liquid storage chamber 1 in sequence, so as to achieve ventilation. In addition, by arranging the first air guide groove 222 and the first liquid inlet hole 211 opposite to each other, the effect of the above-mentioned liquid storage space 25 can be achieved, and the suction waiting time can be shortened.

[0082] Optionally, refer to Figure 8 , Fig. 9 , a plurality of first air guide grooves 222 arranged circumferentially may be provided on the surface of the liquid storage member 22 facing the outer tube 21; the provision method may be to dig grooves on the surface of the liquid storage member 22, or to install ridges on the liquid storage member 22. Each first air guide groove 222 is longitudinally elongated, and its length direction is the same as the axial direction of the liquid storage member 22. Secondly, the number of first air guide grooves 222 may be greater than the number of first liquid inlet holes 211, and some of the first air guide grooves 222 among the plurality of first air guide grooves 222 may be respectively arranged opposite to each first liquid inlet hole 211 in the radial direction of the outer tube 21; of course, the number of first air guide grooves 222 may also be the same as the number of first liquid inlet holes 211, and each first air guide groove 222 may be arranged opposite to each first liquid inlet hole 211 in the radial direction of the outer tube 21, which is not limited here.

[0083] Example 3

[0084] See also Fig.10 The atomizer 100 of this embodiment is modified on the basis of the embodiment 1. The main modifications are the formation position of the first air channel 4 and the relative position of the first liquid inlet hole 211; the following describes the structures of the atomizer 100 of embodiment 3 that are different from those of embodiment 1, and the other structures of the atomizer 100 not mentioned can refer to embodiment 1 and will not be described here.

[0085] In this embodiment, if Fig.10 As shown, the first liquid inlet 211 is located on the outer peripheral side of the liquid storage member 22, and is relatively located on the side of the base 24 facing the liquid storage member 22. The base 24 is a cylindrical structure, and its outer peripheral side wall fits with the inner peripheral side wall of the outer tube 21 to play a sealing role.

[0086] The atomizer core 2 further includes an inner tube 26 between the outer tube 21 and the liquid storage member 22 . The inner tube 26 can be placed on the base 24 like the liquid storage member 22 . At this time, the first liquid inlet hole 211 is relatively located on the outer peripheral side of the inner tube 26 .

[0087] A gap space 27 is left between the inner tube 26 and the outer tube 21 to form a first air channel 4; the gap space 27 is used to connect the central channel 221 of the liquid storage member 22 with the first liquid inlet hole 211. It can be understood that the airflow entering from the air inlet end 31 can pass through the central channel 221 of the liquid storage member 22, the gap space 27, the first liquid inlet hole 211, and the liquid storage chamber 1 in sequence, thereby achieving ventilation. Since the base 24 and the outer tube 21 are sealed, the airflow and liquid will not leak out from between the base 24 and the outer tube 21.

[0098] Further optionally, the injection hole 61 is cylindrical. The injection plug 62 may include a first column section 621 inserted into the injection hole 61, and a second column section 622 located outside the injection hole 61 and in contact with the outside air.
