[0040] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration, not limitation, to facilitate a thorough understanding of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention may 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 obscuring the description of the present invention with unnecessary detail.

[0041] The utility model constructs an electronic atomization device, which may include an atomization assembly 100 (refer to Figure 1 ) and a host (not shown). The host is coupled to one end of the atomizer assembly 100 and is electrically connected to the atomizer assembly 100 to supply power to drive the atomizer assembly 100 to operate. The atomizer assembly 100 may store a liquid aerosol-generating matrix, such as a liquid medicine or a liquid such as a plant leaf. Furthermore, when powered, the atomizer assembly 100 heats and atomizes the aerosol-generating matrix to form an aerosol.

[0042] The aerosol can be used in different places, such as atomization treatment, atomization beauty, leisure inhalation, etc. The following embodiments are all described by taking the electronic atomization device as an example of generating aerosol for user inhalation.

[0043] Furthermore, the atomizer assembly 100 and the main unit can be of a separate design, that is, the atomizer assembly 100 and the main unit can be disassembled and connected; this design can facilitate the independent production and sales of the atomizer assembly 100 and the main unit. For example, the atomizer assembly 100 and the main unit can be connected by magnetic attraction, plug-in connection, etc.

[0044] The specific structure and related functions of the atomization assembly 100 can be found in the following embodiments and are not discussed here.

[0045] The main unit may include a battery and a controller. The battery is used to provide power to the atomizer assembly 100; the controller is used to control the operation of the atomizer assembly 100. The main unit may also include other components such as a battery holder and an airflow sensor. These components can be found in related art and will not be described in detail here.

[0046] The electronic atomization device further includes a first air flow channel 1 formed in the atomization assembly 100 (see Figure 2 ), and a second air flow channel (not shown) formed in the host; the first air flow channel 1 and the second air flow channel can be connected to each other, and can be connected to the outside of the electronic atomization device respectively; the first air flow channel 1 is arranged at a downstream position of the second air flow channel. When the user draws air to the electronic atomization device, the ambient air can flow through the second air flow channel to reach the first air flow channel 1, and mix with the atomized aerosol-generating matrix to form an aerosol. At the same time, the airflow generated by the suction can bring the aerosol to the outside of the electronic atomization device, and then be inhaled by the user.

[0047] The structure of the atomizing assembly 100 is described in detail below. Figure 2 and Figure 3 The atomization assembly 100 may include an outer tube 2 and a heating module 3 .

[0048] Please refer to Figure 3 A cavity 23 for at least loading an aerosol generating matrix is ​​provided in the outer tube 2 , and the heating module 3 can be inserted into and installed in the cavity 23 .

[0049] Then see Figure 2 The heating module 3 may be provided with a first liquid storage space 41, which together with part of the space in the cavity 23 forms a liquid storage chamber 4 for storing the aerosol-generating substrate. The heating module 3 also includes a heating core 31 in fluid communication with the first liquid storage space 41. The fluid communication described herein can be understood as allowing liquid to flow between the first liquid storage space 41 and the heating core 31. The aerosol-generating substrate in the liquid storage chamber 4 can be transferred to the heating core 31, where it is heated and atomized.

[0050] Secondly, review Figure 3 A first flow channel 11 is formed inside the outer tube 2, and at the same time, a second flow channel 12 is formed in the heating module 3; the first flow channel 11 and the second flow channel 12 can be connected to form the first airflow channel 1 mentioned above; wherein, the second flow channel 12 is arranged at the upstream position of the first flow channel 11.

[0051] Continuing to look at the structure of outer tube 2 and heating module 3, you can refer to Figure 3 , the outer tube 2 can be a longitudinal structure. Secondly, the outer tube 2 can also be a transparent tube body, so that the user can observe the liquid storage situation of the liquid storage chamber 4 from the outside of the outer tube 2.

[0052] like Figure 3 As shown, the outer tube 2 has two opposite ends in the longitudinal direction (parallel to / coinciding with the length direction or axial direction of the outer tube 2); a cavity 23 is formed between the two ends. The cavity 23 can be a flat cylindrical channel. Of course, the shape of the cavity 23 can also be other shapes, such as cylindrical, square column, etc., which are not limited here. An air outlet 25 is provided at one end of the outer tube 2; for the sake of simplicity, the end of the outer tube 2 provided with the air outlet 25 is referred to as the first end 21, and the other end of the outer tube 2 is referred to as the second end 22; the second end 22 of the outer tube 2 is open to allow the heating module 3 to be inserted into the cavity 23. At the same time, a hollow conduit 24 is provided in the cavity 23 of the outer tube 2; one end of the conduit 24 is connected to the first end 21 of the outer tube 2 and is communicated with the air outlet 25 to jointly form a first flow channel 11, and the other end of the conduit 24 is provided in the cavity 23 and maintains a distance from the second end 22 to provide a basis for connecting with the heating core 31 of the heating module 3.

[0053] The heating module 3 can be inserted into and installed in the cavity 23 from the second end 22. Figure 2 When the heating module 3 is inserted, the second flow channel 12 in the heating module 3 and the first flow channel 11 in the outer tube 2 can be connected; at the same time, the heating module 3 and the wall of the cavity 23 synchronously define the liquid storage cavity 4, and the liquid storage cavity 4 can include a first liquid storage space 41 located in the heating module 3, and a second liquid storage space 42 located in the cavity 23, between the inner top of the cavity 23 (which can be understood as the side of the cavity 23 close to the first end 21) and the heating module 3.

[0054] Continue to refer Figure 2The atomizer assembly 100 may also include two sealing plugs 5 for blocking the first air flow channel 1. The two sealing plugs 5 may respectively block the two ports of the first air flow channel 1, namely the ports of the first flow channel 11 and the second flow channel 12 away from each other. It can be understood that when the atomizer assembly 100 is assembled, under the influence of air pressure, the aerosol generating matrix is ​​likely to seep from the heating core 31 of the atomizer assembly 100, and eventually develop into leakage; and if the first air flow channel 1 is blocked, the interior of the atomizer assembly 100 can be made relatively airtight, and the influence of atmospheric pressure on the atomizer assembly 100 is reduced, which can effectively slow down the seepage of the aerosol generating matrix from the heating core 31, which is beneficial to the storage and transportation of the atomizer assembly 100. It can be supplemented here that in other related technologies, the atomizer assembly 100 and the host may be an integrated design; in this case, the two sealing plugs 5 can choose to respectively block the ports of the first air flow channel 1 and the second air flow channel away from each other.

[0055] Further, see Figure 3 , the cavity 23 forms a rated capacity filling line (hereinafter referred to as the rated filling line 6) during assembly. It can be supplemented here that in the production process of the atomizer assembly 100 of the present invention, the second end 22 of the outer tube 2 will be set upward; then, the aerosol generating matrix is ​​injected into the outer tube 2. At this time, the liquid level of the aerosol generating matrix is ​​based on the top of the cavity 23, and the height line in the cavity 23 is the filling line; and the rated filling line 6 is the liquid level height line when the injection amount is the same as the rated capacity of the liquid storage chamber 4. Optionally, a scale line can be set on the wall of the cavity 23 to indicate the rated filling line 6 to ensure that the assembler has filled the liquid in place; of course, if the filling step is performed by a robot, since the injection amount of each outer tube 2 is controllable, a scale line may not be set.

[0056] During assembly, a portion of the heating module 3 can displace a portion of the aerosol-generating substrate into the first liquid storage space 41 to fill the liquid storage chamber 4. This ensures that the aerosol-generating substrate fills the entire liquid storage chamber 4, provided that the liquid storage chamber 4 has sufficient capacity. This portion of the heating module 3 can be referred to as a filling structure 323.

[0057] It is understandable that the rated liquid filling line 6 generally cannot exceed the end of the conduit 24 close to the second end 22 or the end of the heating core 31 close to the second end 22, because if it exceeds, the aerosol generating substrate will flow into the conduit 24. Therefore, the electronic atomization device in the related art may have the following problems:

[0058] The first case is that the rated capacity of the liquid storage chamber 4 is designed to be relatively small; in some related technologies, the side of the liquid storage chamber 4 close to the second end 22 is arranged between the first end 21 and the conduit 24, and the rated liquid filling line 6 is arranged to be flush with the position of the side of the liquid storage chamber 4 close to the second end 22, so that the aerosol generating matrix can fill the entire liquid storage chamber 4. However, with this design, the total time that the electronic atomization device can support inhalation is relatively short.

[0059] The second situation is that the rated capacity of the liquid storage chamber 4 is designed to be relatively large; in some related technologies, the side of the liquid storage chamber 4 close to the second end 22 is set between the conduit 24 and the end of the heating core 31 close to the second end 22, and the rated liquid filling line 6 is set to be flush with the position of the side of the liquid storage chamber 4 close to the second end 22, so that the aerosol generating matrix can fill the entire liquid storage chamber 4; however, this method will cause the atomization assembly 100 to be assembled within a preset time after liquid filling, otherwise the contact time between the aerosol generating matrix and the heating core 31 is too long, and the aerosol generating matrix will leak from the heating core 31. It can be supplemented here that in this related technology, the atomization assembly 100 generally needs to complete the remaining assembly within 2 minutes after liquid filling.

[0060] The third situation is that the shape of the liquid storage chamber 4 is designed to be relatively large, so as to control the position of the side of the liquid storage chamber 4 close to the second end 22 to be between the first end 21 and the conduit 24 under the premise of ensuring that the rated capacity of the liquid storage chamber 4 is sufficient. However, this method is not conducive to the miniaturization of the electronic atomization device, and is not conducive to the carrying and holding of the electronic atomization device.

[0061] The fourth case is that the design of the liquid storage chamber 4 is the same as that of the second case, but the liquid storage chamber 4 is not filled, that is, the liquid filling line is located between the heating core 31 and the inner top of the cavity 23, so as to avoid the aerosol generating matrix from being in contact with the heating core 31 for too long during the assembly of the atomizing assembly 100. However, this method will cause the internal air pressure of the liquid storage chamber 4 to be relatively high, making the atomizing assembly 100 before formal use easily affected by the air pressure, causing the aerosol generating matrix to leak from the heating core 31, thereby affecting the user's initial experience. It can be supplemented here that since the aerosol generating matrix will be in contact with the heating core 31; if the internal air pressure of the liquid storage chamber 4 is greater than the external air pressure, the downward liquid tendency will become stronger, and the aerosol generating matrix will easily leak into the heating core 31, thereby causing leakage.

[0062] In the present invention, during the liquid injection, the rated capacity of the aerosol generating matrix is ​​injected with the second end 22 of the outer tube 2 facing upward to form the rated liquid injection line 6. Subsequently, the heating module 3 is installed in the cavity 23, as shown in Figure 3. At this time, the filling structure 323 of the heating module 3 is located between the inner top of the cavity 23 and the rated liquid injection line 6 in the longitudinal direction. In other words, the filling structure 323 will be immersed in the aerosol generating matrix. According to the principle of volume displacement, the liquid level of the aerosol generating matrix rises, and the aerosol generating matrix occupied by the filling structure 323 can flow into the space in the liquid storage chamber 4 above the rated liquid injection line 6 and fill it; in this way, it can be ensured that the liquid storage chamber 4 has sufficient rated capacity and can also be fully loaded.

[0063] At the same time, the full filling of the liquid storage chamber 4 of the present invention can also help reduce the total volume of bubbles in the liquid storage chamber 4, thereby further preventing leakage. It is understandable that during the liquid filling process, air will escape into the aerosol generating matrix, generating multiple bubbles of varying sizes. The presence of bubbles will cause the air pressure in the liquid storage chamber 4 to increase. By filling the liquid storage chamber 4, the volume of large bubbles can be reduced and the number of small bubbles can be reduced, thereby reducing the total volume of bubbles in the liquid storage chamber 4.

[0064] Secondly, since the heating module 3 can be used as an integral module, during the mass production of the atomization assembly 100, the heating module 3 can be assembled first, and after the outer tube 2 is uniformly filled with liquid, the heating module 3 can be directly pressed into the corresponding outer tube 2 to complete the assembly.

[0065] Understandably, such a design can improve the feasibility of production operations, ignoring the requirement that the atomizer assembly 100 must be assembled after liquid injection within a specified time. As mentioned above, the aerosol generating matrix can leak from the heating core 31; and in the related art, with respect to the second case mentioned above, the assembly steps are to first install the heating core 31 into the outer tube 2 to form a complete liquid storage chamber 4, then inject liquid, and finally install the other loose parts of the atomizer assembly 100 into the outer tube 2. Therefore, it is necessary to complete the assembly as soon as possible after liquid injection, because the completion of liquid injection means that the heating core 31 is in contact with the aerosol generating matrix. If the contact time between the aerosol generating matrix and the heating core 31 is too long, the aerosol generating matrix will leak from the heating core 31. In the present invention, influenced by the design of the internal structure of the atomizing assembly 100, on the one hand, the liquid can be injected first and then the heating module 3 can be installed, so that the heating core 31 will not come into contact with the aerosol generating matrix before the heating module 3 is installed. On the other hand, the two sealing plugs 5 can be pre-sealed at the ports of the first flow channel 11 and the second flow channel 12 that are away from each other. Then, when the heating module 3 is inserted into the outer tube 2, the first air flow channel 1 is sealed, which greatly limits the penetration of the aerosol generating matrix into the heating core 31.

[0066] Optionally, see Figure 4 , the heating module 3 may include a sealing member 32. The sealing member 32 may be used for sealing; the external shape and circumferential size of the sealing member 32 may be comparable to that of the cavity 23; the external shape of the sealing member 32 may be a flat columnar shape, a cylindrical shape, a square columnar shape, etc., which is not limited here. That is to say, after the sealing member 32 is inserted into the outer tube 2, at least part of the circumferential wall of the sealing member 32 is in close contact with the wall of the cavity 23 to prevent liquid from leaking from between the sealing member 32 and the wall of the cavity 23, thereby achieving a sealing effect. The sealing member 32 is provided with a chamber 3221, which may be used to form a first liquid storage space 41 and to accommodate the heating core 31.

[0067] Please read back Figure 3 The heating core 31 can be a longitudinal structure, and the end of the heating core 31 close to the second end 22 is inserted into the side of the chamber 3221 close to the second end 22, which can also play a role in preventing the aerosol generating matrix from directly leaking out; the end of the heating core 31 close to the first end 21 extends toward the first end 21 and is located in the chamber 3221.

[0068] Continue as Figure 3 As shown, there is a distance between the outer peripheral side wall of the heating core 31 and the peripheral wall of the chamber 3221. The remaining space in the chamber 3221 except the space occupied by the heating core 31 can be used as the first liquid storage space 41. At least part of the space of the first liquid storage space 41 is distributed on the outer circumference of the heating core 31, for example, on two opposite sides of the circumference of the heating core 31. The aerosol generating matrix can penetrate into the heating core 31 from the two opposite sides of the circumference of the heating core 31. Since the aerosol generating matrix can reach the heating core 31 along the circumferential direction of the heating core 31, there is sufficient contact area between the aerosol generating matrix and the heating core 31, which is conducive to weakening the burnt taste produced during inhalation.

[0069] Optionally, refer to Figure 4The wall of the chamber 3221 may also be provided with a plurality of microgrooves 3223 for generating capillary forces. These microgrooves 3223 can reduce the size of bubbles in the liquid storage chamber 4 and eliminate bubbles, thereby solving the problem of bitter and burnt taste in the puff and reducing leakage of the atomization assembly 100 during transportation. It can be understood from the above that bubbles will affect the air pressure inside the liquid storage chamber 4, thereby causing leakage problems; in addition, during the puffing period, bubbles can move to the contact position between the aerosol generating matrix and the heating core 31, hindering the aerosol generating matrix from being transferred to the heating core 31. The heating core 31 does not receive sufficient aerosol generating matrix, and naturally dry burning will occur, resulting in a bitter and burnt taste in the puffing; and the capillary force will further decompose the bubbles into smaller bubbles, or even make them disappear. Further optionally, each microgroove 3223 is generally arranged longitudinally. The generally longitudinal arrangement mentioned here means that the microgroove 3223 extends from the side close to the first end 21 toward the second end 22. The length direction of the microgroove 3223 can be completely parallel to the longitudinal direction or inclined to the longitudinal direction.

[0070] In some embodiments, see Figure 4 The sealing member 32 may include a base 321 and a sealing seat 322. The base 321 is used to seal the second end 22; an air inlet duct 3211 for air to pass through is also provided in the base 321. The sealing seat 322 is provided in the cavity 23 and is installed on the side of the base 321 away from the second end 22. The sealing seat 322 may be a longitudinal structure, such as Figure 3 As shown, one end of the filling structure 323 is positioned between the inner ceiling of the cavity 23 and the nominal filling line 6, while the other end extends toward the second end 22 and connects to the base 321. The filling structure 323 is a structure on the sealing seat 322, bounded by the nominal filling line 6 and near the first end 21. The volume of the filling structure 323 is comparable to the volume of the space within the liquid storage chamber 4, bounded by the nominal filling line 6 and near the second end 22, thereby ensuring that the liquid storage chamber 4 can be fully loaded with the aerosol-generating substrate.

[0071] like Figure 4 As shown, the chamber 3221 is formed in the sealing seat 322, which is concave along the side of the sealing seat 322 toward the first end 21. The sealing seat 322 is further provided with a through hole 3222 between the chamber 3221 and the air inlet channel 3211 of the base 321 to connect the chamber 3221 and the air inlet channel 3211.

[0072] Can be reviewed Figure 3The heating element 31 is placed in the sealing seat 322. The heating element 31 also has a central channel 311 for air circulation. The atomized aerosol-generating substrate can be precipitated into the central channel 311. In this way, the through hole 3222 of the sealing seat 322 and the air inlet channel 3211 of the base 321 can form an internal channel of the sealing member 32, which is connected to the central channel 311 of the heating element 31 to form the second flow channel 12.

[0073] For reference Figure 2 The end of the conduit 24 away from the first end 21 extends into the sealing seat 322 and connects with the end of the heating core 31 closer to the first end 21, thereby completing the connection between the first flow channel 11 and the second flow channel 12. A sealing ring 7 can also be provided at the connection between the heating core 31 and the conduit 24, that is, at the junction of the first flow channel 11 and the second flow channel 12, to ensure the sealing of the connection between the first flow channel 11 and the second flow channel 12 and prevent leakage of the aerosol generating substrate.

[0074] For reference Figure 5 The heating core 31 may include a cylindrical conducting portion 312 and a heating portion 313 installed in the conducting portion 312. The aerosol-generating matrix in the liquid storage chamber 4 can be conducted by the conducting portion 312 to the heating portion 313, and then heated and atomized by the heating portion 313. It can be explained here that the conducting portion 312 can achieve liquid conduction through capillary action; for example, the conducting portion 312 is made of a porous material, or a plurality of capillary channels are provided on the conducting portion 312. The heating portion 313 can generate heat based on the principle of resistive heating.

[0075] In order to achieve heating when powered on, please refer to Figure 4 The heating module 3 may further include two conductive members 33 inserted into the sealing member 32. The heating portion 313 is electrically connected to the two conductive members 33. The electrical energy released by the battery of the host can be conducted to the heating portion 313 through the two conductive members 33. It can be understood that the two conductive members 33 are a preferred solution to avoid the trouble of wiring and facilitate the design of the atomization assembly 100 and the host to be separated. In other embodiments, the heating portion 313 can also be directly connected to the battery through electrode leads.

[0076] The two conductive members 33 are independently positioned. Each conductive member 33 is inserted from the base 321 and extends into the sealing seat 322. One end of the conductive member 33 is exposed outside the base 321 to facilitate electrical connection with the host's battery. This insertion of the conductive member 33 from the base 321 into the sealing seat 322 also helps improve the reliability of the connection between the sealing seat 322 and the base 321.

[0077] Look again Figure 6The present invention also provides another atomizing assembly 100. The difference between the atomizing assembly 100 of this embodiment and the atomizing assembly 100 described above is that, in this embodiment, Figure 6 As shown, the filling structure 323 is coupled to the side of the sealing seat 322 facing the first end 21, and the filling structure 323 is disposed between the rated filling line 6 and the first end 21. The chamber 3221 may include a first cavity segment disposed in the filling structure 323 and a second cavity segment disposed in the sealing seat 322; the first cavity segment is relatively close to the first end 21 and communicates with the second cavity segment.

[0078] For reference Figure 7 The filling structure 323 may include two filling blocks 3231 arranged on the end of the sealing seat 322 facing the first end 21. The two filling blocks 3231 are arranged at intervals and are respectively located on opposite sides of the sealing seat 322. A first cavity section is formed between the two filling blocks 3231.

[0079] In summary, the atomizer assembly 100 of the present invention is provided with a filling structure 323 at the heating module 3. When the cavity 23 is loaded with an aerosol generating matrix and the heating module 3 is installed in the cavity 23, the filling structure 323 can be immersed in the aerosol generating matrix, and part of the aerosol generating matrix is ​​expelled to the side of the liquid storage chamber 4 close to the second end 22, thereby reducing the volume occupied by the air in the liquid storage chamber 4, and effectively reducing the probability of seepage and leakage of the atomizer assembly 100 before it is officially used.

[0080] In particular, when the cavity 23 is fully loaded with the aerosol generating matrix, the filling structure 323 can allow the aerosol generating matrix to fill the entire liquid storage cavity 4, and the volume occupied by the air in the liquid storage cavity 4 is greatly reduced, or even zero, effectively avoiding the occurrence of liquid seepage and leakage of the atomization assembly 100 before formal use.

[0081] Moreover, a heating core 31 is provided in the heating module 3, and the heating module 3 is directly installed in the cavity 23 as an integral module after liquid injection. In this way, the requirement that the atomization assembly 100 of the related technology needs to complete the assembly after liquid injection within a specified time can be ignored, thereby avoiding the problem of leakage caused by the contact time between the aerosol generating matrix and the heating core 31 being too long, and also improving the feasibility of production operations.

[0082] It can be understood that the above embodiments only express the preferred implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the present invention. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present invention, the above technical features can be freely combined, and several deformations and improvements can be made, all of which fall within the scope of protection of the present invention. Therefore, all equivalent changes and modifications made to the scope of the claims of the present invention should fall within the scope of coverage of the claims of the present invention.
