Abstract

This application provides an atomizing component, an atomizer, and an atomizing device, belonging to the technical field of atomizing devices. The atomizing component includes an atomizing core, a first liquid guiding element, and an atomizing cover. The atomizing core has a liquid inlet hole. The first liquid guiding element is sleeved outside the atomizing core, and the atomizing cover is sleeved outside the first liquid guiding element. The atomizing cover includes a first section and a second section. The first section is directly opposite the liquid inlet hole and has a central liquid guiding hole. The second section is near the end of the atomizing cover and has a bottom liquid guiding hole. Because the first section and the second section of the atomizing cover have a central liquid guiding hole and a bottom liquid guiding hole, respectively, the aerosol matrix can penetrate into the first liquid guiding element through the bottom liquid guiding hole and the central liquid guiding hole, and then penetrate into the atomizing core. In addition, compared to making the central liquid guiding hole and the bottom liquid guiding hole connected, the area of ​​the liquid guiding holes on the atomizing cover can be reduced, and the amount of liquid entering the atomizing core is stable when the amount of aerosol matrix in the atomizer is small.

Description

Technical Field

[0001] This application belongs to the field of atomizing device technology, and particularly relates to an atomizing component, atomizer and atomizing device. Background Technology

[0002] Atomizing devices are instruments used to heat an aerosol matrix to generate an aerosol. Some atomizing devices are sold without an aerosol matrix, requiring users to inject it themselves. Each atomizing device contains an atomizing component with liquid guide holes on its outer surface. Designing these holes to ensure the aerosol matrix fully wets the atomizing component during injection while simultaneously preventing excessive liquid flow during aspiration is a crucial problem that needs to be solved. Utility Model Content

[0003] The purpose of this application is to provide an atomizing component, atomizer, and atomizing device to solve the technical problem in the prior art of how to design the liquid guiding hole so that the atomizing component can be fully wetted by the atomizing matrix when the user injects the atomizer into the atomizer, while also ensuring that the liquid inflow rate from the liquid guiding hole is not too high when the atomizer is drawn in.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: The first aspect of this application provides an atomizing component, comprising:

[0005] Atomizer core, which has a liquid inlet hole;

[0006] The first liquid guiding component is fitted outside the atomizing core;

[0007] An atomizing cover is fitted over the first liquid guiding component. The atomizing cover includes a first section and a second section. The first section faces the liquid inlet hole along the radial direction of the atomizing component. A central liquid guiding hole is provided on the first section, and a bottom liquid guiding hole faces the first liquid guiding component. The second section is near the end of the atomizing cover. A bottom liquid guiding hole is provided on the second section, and the bottom liquid guiding hole faces the first liquid guiding component.

[0008] In some implementations, the sum of the areas of the middle liquid guiding holes in the first section is greater than the sum of the areas of the bottom liquid guiding holes in the second section.

[0009] In some implementations, there are multiple central and bottom liquid guiding holes, and the area of ​​each bottom liquid guiding hole is smaller than the area of ​​any central liquid guiding hole.

[0010] In some implementations, multiple bottom liquid guiding holes are spaced apart in the circumferential direction in the second section; and / or, middle liquid guiding holes are spaced apart in the circumferential direction in the first section.

[0011] In some implementations, the central liquid guide hole includes a longitudinal extension section whose length extends along the axis of the atomizing outer cover, and a transverse section extends along the circumferential direction of the atomizing outer cover.

[0012] In some implementations, the atomizing core includes a heating element, a second liquid guiding element, and a support cylinder, which are sequentially arranged from the inside to the outside. The support cylinder is provided with a liquid inlet hole, and the first section is directly opposite the second liquid guiding element.

[0013] In some implementations, the atomizing assembly further includes a first seal, which is disposed at one end of the first liquid guide along the axial direction. The first seal is sleeved between the atomizing outer cover and the support cylinder, and the bottom liquid guide hole is close to the first seal.

[0014] In some implementations, the atomizing component also includes an atomizing base, which is inserted into the support cylinder and close to the end of the support cylinder. The outer circumferential side of the atomizing base is provided with at least two guide grooves, which are spaced apart along the circumferential direction of the atomizing base. The heating element includes pins, which are arranged one-to-one with the guide grooves, and each pin leads to the corresponding guide groove.

[0015] A second aspect of this application provides an atomizer, including the atomizing component provided by any of the above-described technical solutions.

[0016] In some implementations, the atomizer also includes a chamber and a base. The base is installed at one end of the chamber. One end of the atomizing component is sealed to the base, and the other end is sealed to the inner side of the chamber. The bottom liquid guide hole is close to the base. The chamber is provided with a liquid injection hole, which is located on the side of the chamber away from the base. A liquid injection plug is inserted into the liquid injection hole.

[0017] A third aspect of this application provides an atomizing device, including a battery unit and an atomizer provided by any of the above-described technical solutions, wherein one end of the battery unit is connected to the atomizer.

[0018] The beneficial effects of this application are as follows: In this embodiment, by providing a central liquid guiding hole and a bottom liquid guiding hole in the first and second sections of the atomizing outer cover, when an aerosol matrix is ​​injected into the liquid storage chamber, the aerosol matrix can penetrate into the first liquid guiding component through the bottom and central liquid guiding holes and then into the atomizing core. Since the first section is directly opposite the liquid inlet hole on the atomizing core, the aerosol matrix in the liquid storage chamber can directly penetrate into the atomizing core through the liquid inlet hole on the atomizing core after entering the first liquid guiding component through the central liquid guiding hole on the first section, which is beneficial for fully wetting the atomizing core; when using the atomizing core... In the atomizing device, since the first and second sections of the atomizing outer cover are respectively provided with a middle liquid guiding hole and a bottom liquid guiding hole, the area of ​​the liquid guiding holes on the atomizing outer cover can be reduced compared to the case where the middle liquid guiding hole and the bottom liquid guiding hole are connected. This is to balance the situation where the aerosol matrix in the atomizer is small, and the rate of aerosol matrix entering the first liquid guiding component from the liquid guiding hole of the atomizing outer cover increases. This makes the liquid inflow into the atomizing core stable and avoids the oil leakage caused by the excessive liquid inflow rate from the liquid guiding hole when the aerosol matrix in the atomizer is small, as is the case in existing related technologies.

[0055] Regarding the battery section 20, it typically contains a battery and circuit board, etc. The battery section 20 provides the necessary power to the atomizer 10 through the built-in battery, enabling the atomizer 10 to work normally.

[0056] Regarding the connection method between the battery section 20 and the atomizer 10, the battery section 20 and the atomizer 10 can be detachably connected, for example, they can be connected by a snap-fit ​​or magnetic adsorption; or, the battery section 20 and the atomizer 10 can be non-detachably connected.

[0057] Please see Figures 3-5 , Figure 3 This is a top view schematic diagram of the atomizer 10 provided in some embodiments of this application. Figure 4 for Figure 3 Schematic diagram of the sectional view along the middle AA direction. Figure 5 for Figure 3 Schematic diagram of sectional view in the middle BB direction ( Figure 5 The cotton swab 30 is not shown in the image.

[0058] Please see Figure 4The atomizer 10 provided in this application embodiment includes an atomizing component 1, which is located inside the atomizer 10 and is used to heat the aerosol matrix that has penetrated into it.

[0059] See some examples. Figure 4 The atomizer 10 also includes a chamber 2 and a base 3. The base 3 is installed at one end of the chamber 2. One end of the atomizing component 1 is sealed to the base 3 and the other end is sealed to the inner side of the chamber 2. The space between the chamber 2 and the atomizing component 1 forms a liquid storage chamber 4, which is used to contain the aerosol matrix.

[0060] Please see Figure 4 The chamber 2 includes a main body 21 and a suction nozzle 22. The main body 21 is connected to one end of the suction nozzle 22, and the base 3 is located at the end of the main body 21 opposite to the suction nozzle 22. Please refer to [link / reference]. Figure 4 The mouthpiece 22 has an air intake channel 221 inside, which is connected to the inside of the atomizing component 1. In some examples, the mouthpiece 22 can be integrally formed with the main body 21 of the chamber, or the mouthpiece 22 can be detachably connected to the main body 21 of the chamber.

[0061] See some examples. Figure 4 The base 3 includes a base support part 31 and a base first sealing part 32. The base support part 31 is disposed inside the chamber body 21 and connected to the chamber body 21. For example, the base support part 31 can be snapped into the chamber body 21. The base first sealing part 32 is disposed on the side of the base support part 31 facing the mouthpiece 22. The base first sealing part 32 is mounted on the base support part 31. The bottom of the atomizing component 1 is supported on the base support part 31. The base first sealing part 32 seals the bottom of the chamber body 21 and the atomizing component 1.

[0062] See some examples. Figure 4 The base 3 also includes a base second sealing part 33, which is disposed inside the main body 21 and located on the side of the base support part 31 facing away from the suction nozzle 22. The base second sealing part 33 is used to seal and cooperate with the battery part 20.

[0063] Please see Figure 4 The atomizing component 1 includes an atomizing core 11, which is electrically connected to the battery in the battery unit 20. When current flows through the atomizing core 11, it generates heat. Specifically, when the atomizing core 11 is working, it can also heat the aerosol matrix that has penetrated into the atomizing core 11, causing it to evaporate. When the user inhales through the mouthpiece 22, causing airflow within the atomizing core 11, the evaporated aerosol matrix can form mist under the condensation effect of the airflow. Finally, the mist can flow with the airflow to the mouthpiece 22.

[0064] Please see Figure 4 and Figure 5 The atomizing component 1 provided in this application embodiment also includes an atomizing cover 13 and a first liquid guiding component 12. Both the first liquid guiding component 12 and the atomizing cover 13 are cylindrical. The first liquid guiding component 12 is sleeved on the outside of the atomizing core 11, and the atomizing cover 13 is sleeved on the outside of the first liquid guiding component 12. The two ends of the atomizing cover 13 are respectively sealed to the base 3 and the chamber 2.

[0065] Please see Figure 4 The atomizing outer cover 13 is provided with a central liquid guiding hole 131 and a bottom liquid guiding hole 132. Along the radial direction of the atomizing component 1, the central liquid guiding hole 131 and the bottom liquid guiding hole 132 are both facing the first liquid guiding element 12. The aerosol matrix in the liquid storage chamber 4 can flow to the first liquid guiding element 12 through the central liquid guiding hole 131 and the bottom liquid guiding hole 132. The aerosol matrix absorbed by the first liquid guiding element 12 can penetrate into the interior of the atomizing core 11 through the liquid inlet hole 1131 on the atomizing core 11.

[0066] Regarding the positions of the middle liquid guide hole 131 and the bottom liquid guide hole 132, it can also be understood that, please refer to [the relevant documentation / reference]. Figure 4 The atomizing outer cover 13 includes a first section 133 and a second section 134, wherein the first section 133 is directly opposite the liquid inlet 1131. Figure 4 The liquid inlet 1131 is not shown in the diagram. A central liquid guide hole 131 is provided on the first section 133. A bottom liquid guide hole 132 is provided on the second section 134 near the end of the atomizing outer cover 13. Please refer to [link to relevant documentation]. Figure 4 The bottom liquid guiding hole 132 is closer to the base 3 than the middle liquid guiding hole 131.

[0067] In this embodiment, by setting the bottom liquid guiding hole 132 close to the base 3, when the aerosol matrix content in the liquid storage chamber 4 is low, it can still flow to the first liquid guiding component 12 through the bottom liquid guiding hole 132.

[0068] In some examples, multiple bottom liquid guiding holes 132 can be provided, and the multiple bottom liquid guiding holes 132 are spaced apart along the circumferential direction of the atomizing outer cover 13, so that the aerosol matrix in the liquid storage chamber 4 can be evenly penetrated into the first liquid guiding component 12 through the bottom liquid guiding holes 132.

[0069] In some examples, a ring of bottom liquid guiding holes 132 may be provided on the second section 134, or more than two rings of bottom liquid guiding holes 132 may be provided on the second section 134 along the axial direction of the atomizing cover 13.

[0070] In some examples, multiple central liquid guiding holes 131 may be provided, and the multiple central liquid guiding holes 131 are spaced apart along the circumferential direction of the atomizing outer cover 13, so that the aerosol matrix in the liquid storage chamber 4 can be evenly penetrated into the first liquid guiding component 12 through the central liquid guiding holes 131.

[0071] In some examples, a ring of bottom liquid guiding holes 132 may be provided on the first section 133, or two or more rings of middle liquid guiding holes 131 may be provided on the first section 133 along the axial direction of the atomizing cover 13.

[0072] It should be noted that in this embodiment, the first section 133 is directly opposite the liquid inlet hole 1131 on the atomizing core 11, so that the aerosol matrix in the liquid storage chamber 4 can directly penetrate into the atomizing core 11 through the liquid inlet hole 1131 on the atomizing core 11 after entering the first liquid guiding component 12 through the central liquid guiding hole 131 on the first section 133, which is beneficial to improve the efficiency of aerosol matrix penetrating into the atomizing core 11.

[0073] The material of the first liquid guiding component 12 has oil absorption properties. For example, the material of the first liquid guiding component 12 can be organic cotton, ceramic cotton, bamboo fiber cotton, or composite cotton. When the aerosol matrix in the liquid storage chamber 4 enters the first liquid guiding component 12 through the bottom liquid guiding hole 132 on the second section 134, the aerosol matrix that has seeped into the first liquid guiding component 12 will seep upward until it seeps into the atomizing core 11 through the liquid inlet hole 1131 on the atomizing core 11.

[0074] See some examples. Figure 4 The chamber 2 is provided with an injection hole 211, and an injection plug 5 is inserted into the injection hole 211 to seal the injection hole 211. When the injection plug 5 is opened, aerosol matrix can be added into the chamber 2 through the injection hole 211. When the injection plug 5 is inserted into the injection hole 211, it can also prevent the aerosol matrix in the chamber 2 from overflowing through the injection hole 211.

[0075] See some examples. Figure 4 The liquid injection plug 5 can be set on the side of the main body 21 away from the base 3, or the liquid injection plug 5 can be set on the circumferential side of the main body 21 and on the side close to the nozzle 22.

[0076] In some scenarios, the atomizing device 100 is sold without being filled with an aerosol matrix, requiring the user to inject the aerosol matrix into the atomizer 10. When injecting the aerosol matrix, it is necessary to ensure that the aerosol matrix fully wets the atomizing core 11 to prevent dry burning during use of the atomizing device 100, which would affect its normal operation. In this embodiment, since a bottom liquid guiding hole 132 and a middle liquid guiding hole 131 are respectively provided on the atomizing outer cover 13, when the aerosol matrix is ​​injected into the liquid storage chamber 4 and the liquid level of the aerosol matrix is ​​between the bottom liquid guiding hole 132 and the middle liquid guiding hole 131, the aerosol matrix can seep into the first liquid guiding element 12 through the bottom liquid guiding hole 132. When the aerosol matrix continues to be injected into the liquid storage chamber 4 and the liquid level of the aerosol matrix is ​​greater than the height of the middle liquid guiding hole 131, the aerosol matrix can seep into the first liquid guiding element 12 through the bottom liquid guiding hole 132. The aerosol matrix can penetrate into the first liquid guiding element 12 through the bottom liquid guiding hole 132 and the middle liquid guiding hole 131, and then penetrate into the atomizing core 11. Since the first section 133 is directly opposite the liquid inlet hole 1131 on the atomizing core 11, the aerosol matrix in the liquid storage chamber 4 can directly penetrate into the atomizing core 11 through the liquid inlet hole 1131 on the atomizing core 11 after entering the first liquid guiding element 12 through the middle liquid guiding hole 131 on the first section 133, which can facilitate the full wetting of the atomizing core 11.

[0077] When using the atomizing device 100, if the aerosol matrix in the storage chamber 4 is located as follows: Figure 5 When the liquid level line L1 is shown, when the user draws in the suction nozzle 22, the aerosol matrix can seep into the first liquid guiding element 12 through the bottom liquid guiding hole 132 and the middle liquid guiding hole 131, and then into the atomizing core 11. The aerosol matrix in the storage chamber 4 decreases (but the liquid level line of the aerosol matrix is ​​still above the middle liquid guiding hole 131), resulting in a decrease in the gas pressure in the storage chamber 4. Gas outside the atomizing device 100 can enter the storage chamber 4 through the atomizing core 11, the bottom liquid guiding hole 132, and the middle liquid guiding hole 131, and enter the space above the aerosol matrix; if the aerosol matrix in the storage chamber 4 is located as shown... Figure 5 When the liquid level line L2 is shown, part of the middle liquid guide hole 131 is located below the liquid level line L2. When the suction nozzle 22 is used, the aerosol matrix can penetrate into the first liquid guide element 12 through the bottom liquid guide hole 132 and the middle liquid guide hole 131, and then penetrate into the atomizing core 11. Since part of the middle liquid guide hole 131 is located above the liquid level line L2, when the gas pressure in the liquid storage chamber 4 decreases, the gas outside the atomizing device 100 can enter the liquid storage chamber 4 through the part of the middle liquid guide hole 131 located above the liquid level line; when the aerosol matrix in the liquid storage chamber 4 is located as shown, the aerosol matrix is ​​located below the liquid level line L2. Figure 5 When the liquid level line L3 is shown, when it is used for suction nozzle 22, the aerosol matrix can penetrate into the first liquid guide 12 through the bottom liquid guide hole 132 and then into the atomizing core 11. When the gas pressure in the liquid storage chamber 4 decreases, the gas outside the atomizing device 100 can enter the liquid storage chamber 4 through the middle liquid guide hole 131.

[0078] As can be seen from the above, when the aerosol matrix in the storage chamber 4 is located below the middle liquid guide hole 131, when the gas pressure in the storage chamber 4 decreases, the gas outside the atomizing device 100 can enter the storage chamber 4 through the middle liquid guide hole 131. The gas entering the storage chamber 4 will not affect the aerosol matrix entering the first liquid guide element 12 through the bottom liquid guide hole 132. That is, compared with when the aerosol matrix in the storage chamber 4 is located above the bottom liquid guide hole 132 and the middle liquid guide hole 131, the storage chamber 4... When the internal air pressure decreases, external gas needs to enter the storage chamber 4 through the atomizing core 11, the bottom liquid guide hole 132, and the middle liquid guide hole 131. This will affect the liquid inlet rate of the aerosol matrix entering the first liquid guide component 12 through the bottom liquid guide hole 132 and the middle liquid guide hole 131. In other words, when the aerosol matrix in the storage chamber 4 is located below the middle liquid guide hole 131, the rate at which the aerosol matrix enters the first liquid guide component 12 from the bottom liquid guide hole 132 will increase. In this embodiment, since the middle liquid guide hole 131 and the bottom liquid guide hole 132 are respectively provided on the first section 133 and the second section 134, the area of ​​the liquid guide hole on the atomizing cover 13 is reduced compared to the case where the middle liquid guide hole 131 and the bottom liquid guide hole 132 are connected. This is to balance the situation where the aerosol matrix rate increases when there is less aerosol matrix in the atomizer 10, so as to stabilize the liquid inflow into the atomizing core 11.

[0079] In summary, in this embodiment of the application, by providing a central liquid guiding hole 131 and a bottom liquid guiding hole 132 in the first section 133 and the second section 134 of the atomizing outer cover 13 respectively, when the aerosol matrix is ​​injected into the liquid storage cavity 4, the aerosol matrix can penetrate into the first liquid guiding component 12 through the bottom liquid guiding hole 132 and the central liquid guiding hole 131 and then penetrate into the atomizing core 11. Since the first section 133 is directly opposite the liquid inlet hole 1131 on the atomizing core 11, the aerosol matrix in the liquid storage cavity 4 can directly penetrate into the atomizing core 11 through the liquid inlet hole 1131 on the atomizing core 11 after entering the first liquid guiding component 12 through the central liquid guiding hole 131 on the first section 133, which is conducive to fully wetting the atomizing core 11. When the atomizing device 100 is used, since the first section 133 and the second section 134 of the atomizing cover 13 are respectively provided with a middle liquid guiding hole 131 and a bottom liquid guiding hole 132, the area of ​​the liquid guiding holes on the atomizing cover 13 can be reduced compared to the case where the middle liquid guiding hole 131 and the bottom liquid guiding hole 132 are connected. This is to balance the situation where the aerosol matrix in the atomizer 10 is small and the rate of aerosol matrix entering the first liquid guiding component 12 from the liquid guiding hole of the atomizing cover 13 increases as much as possible. This makes the liquid inflow into the atomizing core 11 stable and avoids the situation where the liquid inflow rate from the liquid guiding hole is too large when the aerosol matrix in the atomizer 10 is small, which leads to oil leakage, as is the case in the existing related technology.

[0080] In some embodiments, the sum of the areas of the middle liquid guiding holes 131 on the first section 133 is greater than the sum of the areas of the bottom liquid guiding holes 132 on the second section 134.

[0081] For example, when multiple central liquid guiding holes 131 are provided on the first section 133, the sum of the areas of all central liquid guiding holes 131 on the first section 133 is S1. When multiple bottom liquid guiding holes 132 are provided on the second section 134, the sum of the areas of all bottom liquid guiding holes 132 on the second section 134 is S2, where S1 is greater than S2.

[0082] In this embodiment, by setting the sum of the areas of the middle liquid guiding holes 131 on the first section 133 to be greater than the sum of the areas of the bottom liquid guiding holes 132 on the second section 134, that is, by reducing the area of ​​the liquid guiding holes on the second section 134, the oil leakage caused by the excessive liquid inlet rate from the liquid guiding holes when the aerosol matrix in the atomizer 10 is small is further effectively avoided in the prior art.

[0083] In some embodiments, see Figure 4 The atomizing device 100 also includes a cotton swab 30, which is inserted into the atomizing device 100 through the mouthpiece 22 and extends into the interior of the atomizing core 11.

[0084] When the atomizing device 100 is in transport or for sale, the cotton swab 30 is inserted into the atomizer 10 to prevent dust and other impurities from entering the atomizer 10 through the mouthpiece 22; when the user uses the atomizing device 100, the cotton swab 30 needs to be removed from the atomizer 10.

[0085] Please see Figures 6-7 , Figure 6 This is a schematic diagram of the structure of the atomizing component 1 provided in some embodiments of this application. Figure 7 for Figure 6 A magnified view of a portion of point A in the middle.

[0086] In some embodiments, the bottom liquid guiding hole 132 may be circular, elliptical, or square in shape. See [link to relevant documentation]. Figure 6 This illustrates that the bottom liquid guide hole 132 is circular.

[0087] In some embodiments, see Figure 6 The size and shape of each bottom liquid guiding hole 132 on the second section 134 can be set to be the same.

[0088] In some embodiments, the bottom liquid guiding hole 132 on the second section 134 is a circular hole, and the diameter of the bottom liquid guiding hole 132 ranges from 1 to 10 mm.

[0089] In some embodiments, the size and shape of each central liquid guiding hole 131 on the first section 133 may be the same.

[0090] In some embodiments, see Figure 6 A ring of central liquid guiding holes 131 is provided on the first section 133, and a ring of bottom liquid guiding holes 132 is provided on the second section 134. In some examples, the central liquid guiding holes 131 on the first section 133 and the bottom liquid guiding holes 132 on the second section 134 can be staggered.

[0091] In some embodiments, along the axial direction of the atomizing outer cover 13, two or more central liquid guiding holes 131 are provided on the first section 133, and the central liquid guiding holes 131 of adjacent two rings are staggered.

[0092] In some embodiments, along the axial direction of the atomizing outer cover 13, two or more bottom liquid guiding holes 132 are provided on the second section 134, and the bottom liquid guiding holes 132 of adjacent two rings are staggered.

[0093] In some embodiments, there are multiple central liquid guiding holes 131 and multiple bottom liquid guiding holes 132, and the area of ​​each bottom liquid guiding hole 132 is smaller than the area of ​​any central liquid guiding hole 131.

[0094] In some examples, when the area of ​​each bottom liquid guide hole 132 is smaller than the area of ​​any middle liquid guide hole 131, the number of middle liquid guide holes 131 in the first section 133 can be set to be the same as the number of bottom liquid guide holes 132 in the second section 134; or, the number of middle liquid guide holes 131 in the first section 133 can be set to be greater than the number of bottom liquid guide holes 132 in the second section 134; or, the number of middle liquid guide holes 131 in the first section 133 can be set to be less than the number of bottom liquid guide holes 132 in the second section 134.

[0095] In this embodiment of the application, by setting the area of ​​each bottom liquid guiding hole 132 to be smaller than the area of ​​any middle liquid guiding hole 131, the sum of the areas of each middle liquid guiding hole 131 on the first section 133 is greater than the sum of the areas of each bottom liquid guiding hole 132 on the second section 134.

[0096] The above embodiment describes that the area of ​​each bottom liquid guiding hole 132 is smaller than the area of ​​any middle liquid guiding hole 131. In other embodiments, it is not necessary to set the area of ​​each bottom liquid guiding hole 132 to be smaller than the area of ​​any middle liquid guiding hole 131. It is sufficient to satisfy that the sum of the areas of all middle liquid guiding holes 131 on the first section 133 is greater than the sum of the areas of all bottom liquid guiding holes 132 on the second section 134. For example, the area of ​​the bottom liquid guiding hole 132 can be set to be equal to the area of ​​the middle liquid guiding hole 131. By setting the number of middle liquid guiding holes 131 on the first section 133 to be greater than the number of bottom liquid guiding holes 132 on the second section 134, the sum of the areas of all middle liquid guiding holes 131 on the first section 133 is greater than the sum of the areas of all bottom liquid guiding holes 132 on the second section 134.

[0097] In some embodiments, see Figure 7 The central liquid guide hole 131 includes a longitudinal extension section 1311, the length of which runs along the axial direction of the atomizing outer cover 13.

[0098] Regarding the length direction of the longitudinal extension section 1311 along the axis of the atomizing cover 13, it can be understood that the length direction of the longitudinal extension section 1311 extends from one end of the atomizing cover 13 to the other end of the atomizing cover 13. The length direction of the longitudinal extension section 1311 can be set to be parallel to the axis of the atomizing cover 13, or the length direction of the longitudinal extension section 1311 can be set not to be parallel to the axis of the atomizing cover 13.

[0099] See some examples. Figure 7 The longitudinal extension section 1311 can be set as a rectangular hole, or it can be set as an elliptical hole or a wavy hole.

[0100] In some examples, the length dimension of the longitudinal extension segment 1311 can be set to be 5 to 10 times the width dimension.

[0101] In this embodiment, by setting the length of the longitudinal extension section 1311 along the axial direction of the atomizing cover 13, it is beneficial that when the aerosol matrix is ​​injected into the atomizer 10, as the liquid level of the aerosol matrix gradually rises, the aerosol matrix can continuously seep into the first liquid guide 12 through the longitudinal extension section 1311, which is beneficial for fully wetting the atomizing core 11. In addition, by setting the length of the longitudinal extension section 1311 along the axial direction of the atomizing cover 13, the size of the longitudinal extension section 1311 along the circumferential direction of the atomizing cover 13 can also be minimized, avoiding the liquid inlet rate being too high due to the excessive size of the central liquid guide hole 131.

[0102] In some embodiments, see Figure 7The central liquid guiding hole 131 also includes a transverse section 1312, which is provided at the end of the central liquid guiding hole 131.

[0103] In some examples, the horizontal segment 1312 can be set as a circular hole, an elliptical hole, or a square hole; or, please refer to [link to relevant documentation]. Figure 7 Alternatively, the horizontal segment 1312 can be set as a rectangular hole, and the length direction of the horizontal segment 1312 extends along the circumferential direction of the atomizing cover 13.

[0104] In some examples, the length dimension of the horizontal segment 1312 can be set to be 5 to 10 times the width dimension.

[0105] In some examples, there are multiple central liquid guide holes 131, with each transverse segment 1312 located on the same side of the longitudinal extension segment 1311; or, in other examples, please refer to [reference needed]. Figure 7 In each of the central liquid guiding holes 131, the transverse segments 1312 are staggered at the upper and lower ends of the longitudinal extension segment 1311 so that the transverse segments 1312 of two adjacent central liquid guiding holes 131 can avoid each other.

[0106] In this application, by providing a central liquid guiding hole 131, a transverse section 1312 is also included, which can help increase the area of ​​the central liquid guiding hole 131 and facilitate the aerosol matrix to flow to the first liquid guiding component 12 through the central liquid guiding hole 131.

[0111] In some examples, the second liquid guiding element 112 is cylindrical, and the material of the second liquid guiding element 112 is organic cotton, ceramic cotton, bamboo fiber cotton or composite cotton, etc.

[0112] In this embodiment of the application, by providing the atomizing core 11 with a heating element 111, a second liquid guiding element 112 and a support cylinder 113, the atomizing core 11 can heat the aerosol matrix that has penetrated into it.

[0113] In some embodiments, see Figure 8 The length of the atomizing outer cover 13 along the axial direction is greater than the length of the first liquid guiding component 12 along the axial direction.

[0114] In some embodiments, see Figure 10 The atomizing assembly 1 also includes a first sealing element 14, which is disposed on one side of the first liquid guiding element 12 along the axial direction. The first sealing element 14 is sleeved between the atomizing outer cover 13 and the support cylinder 113, and the bottom liquid guiding hole 132 is close to the first sealing element 14.

[0115] In some examples, the distance between the central axis of the bottom liquid guide hole 132 and the first seal 14 ranges from 1 mm to 5 mm.

[0116] In this embodiment, the inner and outer circumferential sides of the first sealing member 14 are respectively sealed to the support cylinder 113 and the atomizing cover 13 to prevent the aerosol matrix in the first liquid guiding member 12 from overflowing downwards out of the atomizing assembly 1.

[0117] In some embodiments, see Figure 11 The atomizing device 100 includes a second seal 6, which is used to seal the atomizing assembly 1 and the chamber 2.

[0118] See some examples. Figure 11 The chamber body 2 includes an annular plate 23, and a second sealing element 6 is disposed on the side of the annular plate 23 and the atomizing cover 13 away from the base 3. The second sealing element 6 is in sealing cooperation with the annular plate 23 and the atomizing cover 13.

[0119] See some examples. Figure 11 The nozzle 22 has an air intake channel 221 formed inside. The nozzle 22 includes a channel portion 222, and the air intake channel 221 is formed inside the channel portion 222. Please refer to [link / reference]. Figure 11 The channel section 222 is sealed to the second seal 6.

[0120] In some embodiments, see Figure 11The second sealing element 6 includes a first sealing annular segment 61, a second sealing annular segment 62, and a connecting segment 63. The second sealing annular segment 62 is fitted inside the first sealing annular segment 61 with a gap between them.

The first sealing annular segment 61 is disposed between the atomizing outer cover 13 and the annular plate 23. The second sealing annular segment 62 is sealed to the channel portion 222, and one end of the second sealing annular segment 62 is inserted between the atomizing outer cover 13 and the support cylinder 113 and abuts against the end face of the first liquid guiding element 12.

[0121] In this embodiment of the application, by setting the second sealing member 6 including the first sealing annular segment 61, the second sealing annular segment 62 and the connecting segment 63, the atomizing component 1 and the chamber 2 are sealed at the same time, and the position of the first liquid guiding member 12 inside the atomizing outer cover 13 can be limited.

[0122] In some embodiments, see Figure 10 The atomizing assembly 1 also includes an atomizing seat 15, which is inserted into the support cylinder 113 and close to the end of the support cylinder 113. The bottom liquid guiding hole 132 is closer to the atomizing seat 15 than the middle liquid guiding hole 131, that is, the atomizing seat 15 is close to the base 3 of the atomizer 10.

[0123] A guide groove 151 is provided on the outer peripheral side of the atomizing base 15, and the guide groove 151 is spaced apart along the circumferential direction of the atomizing base 153; please refer to Figure 9 The heating element 111 includes pins 1111, and the number of pins 1111 is at least two.
