[0158] It should be noted that the various embodiments / implementations provided in this application can be combined with each other without causing any contradiction. The detailed description in the specific implementation manner should be understood as an explanation of the purpose of this application and should not be regarded as an improper limitation on this application.

[0159] In the description of this application, the terms "upper" and "lower" are based on the orientation shown in Figure 1. It should be understood that these directional terms are merely for the purpose of facilitating the description of this application and simplifying the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "first" and "second" are merely used to distinguish between different objects and do not imply any similarity or connection between the two.

[0160] 1 and 2 , an electronic atomization device 100 according to one embodiment includes an atomization assembly 1 and a replacement assembly 2. The electronic atomization device 100 can be used to contain an atomization medium, such as a liquid medium such as liquid medicine or tobacco liquid, or a semi-solid medium, and atomize it to generate an aerosol for inhalation by a user.

[0161] The atomizer assembly 1 includes an atomizer support 11 and an atomizer core 12. A receiving slot 11b and an assembly slot 11a are formed within the atomizer support 11. The receiving slot 11b stores atomizing medium and supplies it to the atomizer core 12. The atomizing medium introduced from the receiving slot 11b to the atomizer core 12 is atomized into an aerosol by the atomizer core 12. The assembly slot 11a is used to assemble the replacement assembly 2.

[0162] The replacement component 2 is detachably connected to the atomizing component 1, and is used to supply atomizing medium to the receiving tank 11b. In one embodiment, an additional metering chamber 21a can be provided in the replacement component 2 according to the needs of the user. When the replacement component 2 is assembled into the assembly tank 11a, the metering chamber 21a is connected to the receiving tank 11b, and a continuous supply of atomizing medium to the receiving tank 11b can be achieved. A part of the replacement component 2 can be accommodated in the assembly tank 11a. The accommodation method of the replacement component 2 and the assembly tank 11a is not limited. For example, in one embodiment, the replacement component 2 is formed with a first magnetic surface, and the assembly tank 11a has a second magnetic surface, and the first magnetic surface and the second magnetic surface are magnetically matched. In another embodiment, the assembly tank 11a is a groove with an assembly port, and the replacement component 2 is accommodated in the assembly tank 11a through the assembly port and is sealed with the atomizing component 1.

[0163] According to the above-mentioned electronic atomization device 100, since the atomization bracket 11 of the atomization component 1 has a receiving groove 11b for storing the atomization medium and an assembly groove 11a for assembling the replacement component 2, compared with the existing electronic atomization device with only one liquid storage tank, the replacement component 2 can seal the assembly groove 11a when liquid supply is not needed, and the atomization medium is less likely to leak during transportation.

[0164] In one embodiment, referring to Figures 2 and 3, the atomizer assembly 1 also includes an atomizer seat 13 disposed in the receiving groove 11b. The atomizer seat 13 is formed with a mist guide channel 13a and a liquid supply port 13b. The atomizer core 12 is disposed in the mist guide channel 13a of the atomizer seat 13, and the liquid supply port 13b connects the receiving groove 11b and the atomizer core 12. The replacement component 2 has a mist outlet channel 211a and a suction nozzle 211b connected to one end of the mist outlet channel 211a. The mist guide channel 13a is connected to the mist outlet channel 211a. In this embodiment, the atomizer seat 13 is a hollow tubular structure extending up and down, the mist guide channel 13a is a hollow area in the atomizer seat 13, and the liquid supply port 13b is a circular through hole opened on the side wall of the atomizer seat 13. The upper end of the mist guide channel 13a is connected to the lower end of the mist outlet channel 211a. After the atomizing medium in the receiving groove 11b is atomized into an aerosol by the atomizing core 12, the aerosol can flow around the atomizing core 12 into the mist guide channel 13a, and then flow out through the mist outlet channel 211a and the suction nozzle 211b for the user to inhale. In this embodiment, the atomizing core 12 has a hollow mesh structure. In other embodiments, the atomizing core 12 can also have a plate-like structure. In this case, the structure of the atomizing seat 13 can be adapted to the structure of the atomizing core 12, for example, it can also have a plate-like structure.

[0165] The atomization method of the atomizer core 12 is not limited, including but not limited to ultrasonic atomization, vibration atomization, heating atomization and the like. In one embodiment, please refer to Figures 2 and 3, the atomizer core 12 includes a heating body 121 and a liquid conductive liquid 122 coated on the heating body 121. The liquid conductive liquid 122 is used to absorb the atomization medium from the liquid supply port 13b and conduct it to the heating body 121. The material of the liquid conductive liquid 122 includes but is not limited to cotton, porous ceramics, fiber ropes and other porous materials. The atomizer assembly 1 also includes an electrode 14 electrically connected to the heating body 121. When the electrode 14 is energized, it can make the heating body 121 heat up, so that the atomization medium in the liquid conductive liquid 122 is atomized into an aerosol.

[0166] In one embodiment, a cotton wick for storing atomized medium is disposed within the receiving groove 11b, and the cotton wick can supply atomized medium to the guiding liquid 122. The cotton wick has a good adsorption effect on the atomized medium, and the electronic atomization device 100 is unlikely to leak atomized medium during transportation or abnormal upside-down placement.

[0167] In one embodiment, please refer to Figure 2, the replacement component 2 includes a sleeve 21, and the assembly groove 11a is used to detachably accommodate the sleeve 21 of the replacement component 2. That is, the sleeve 21 can be assembled into the assembly groove 11a or removed from the assembly groove 11a according to the actual needs of the user. In one embodiment, the sleeve 21 includes an inner ring shell 211 and an outer ring shell 212, and the outer ring shell 212 is located on the outer periphery of the inner ring shell 211. The outer ring shell 212 is connected to the atomizer bracket 11, and the end of the outer ring shell 212 away from the receiving groove 11b is connected to the end of the inner ring shell 211 away from the receiving groove 11b. The mist outlet channel 211a and the suction nozzle 211b are formed in the inner ring shell 211. Specifically, as shown in Figure 2, the outer ring shell 212 and the inner ring shell 211 are both hollow cylindrical structures extending in the up and down directions. The outer peripheral wall of the lower part of the outer ring shell 212 is sealed and accommodated in the assembly groove 11a. The upper end of the inner ring shell 211 smoothly connects to the upper end of the outer ring shell 212. The inner circumferential wall of the inner ring shell 211 surrounds and forms a mist channel 211a. The upper end of the inner ring shell 211 opens to form a suction nozzle 211b. The lower end of the inner ring shell 211 is connected to the atomizer seat 13, so that the mist outlet channel 211a is connected to the mist guide channel 13a.

[0168] In other words, compared to a solid casing, the casing 21 of this embodiment has a double-layered annular structure consisting of an inner ring shell 211 and an outer ring shell 212, making it lighter. Furthermore, the hollow area between the inner ring shell 211 and the outer ring shell 212 provides thermal insulation, effectively reducing the risk of burns caused by excessive temperature when the aerosol flows through the mist outlet channel 211a of the casing 21, thereby improving the user experience.

[0169] The inner ring shell 211 and the outer ring shell 212 may be in the shape of a circular ring shell, an elliptical ring shell, a square ring shell, or other annular cylindrical structures. The inner ring shell 211 and the outer ring shell 212 are integrally formed, which allows the housing 21 to have a higher structural strength.

[0170] It is understandable that when the mist outlet channel 211a of the electronic atomization device 100 is not provided in the replacement component 2, the replacement component 2 can be a sealing structure that only seals the assembly groove 11a, for example, it is only a cover that is sealed and sleeved in the assembly groove 11a.

[0171] In one embodiment, please refer to Figures 2 and 3, the atomizer bracket 11 includes an annular sleeve 111 with openings at both ends and a partition plate 112 located in the annular sleeve 111. The thickness direction of the partition plate 112 is the same as the up and down direction, and the one side surface (i.e., the upper surface) of the partition plate 112 along the thickness direction is enclosed with the inner circumferential wall of the annular sleeve 111 to form an assembly groove 11a with an opening at the upper end. The other side surface (i.e., the lower surface) of the partition plate 112 along the thickness direction is enclosed with the inner circumferential wall of the annular sleeve 111 to form a receiving groove 11b with an opening at the lower end. A through hole 112a is provided on the partition plate 112, and one end of the mist guide channel 13a is connected to the mist outlet channel 211a through the through hole 112a. In one embodiment, the annular sleeve 111 and the partition plate 112 are integrally formed parts, so that the atomizer bracket 11 has a higher structural strength.

[0172] One end of the inner ring shell 211 is sealed and sleeved with the atomizer seat 13. The sleeve connection method of the inner ring shell 211 and the atomizer seat 13 is not particularly limited. The inner ring shell 211 can be sleeved in the atomizer seat 13, or the atomizer seat 13 can be sleeved in the inner ring shell 211. Please refer to Figure 3. The replacement component 2 also includes a sealing sleeve 22, which is clamped between the inner ring shell 211 and the atomizer seat 13. The sealing sleeve 22 is roughly annular, and the lower end of the inner ring shell 211 extends into the atomizer seat 13 through the through hole 112a of the partition plate 112. The sealing sleeve 22 is sleeved between the outer circumferential wall of the inner ring shell 211 and the inner circumferential wall of the outer ring shell 212. The material of the sealing sleeve 22 is not particularly limited, and includes but is not limited to flexible sealing materials such as rubber, silicone, etc. with good sealing effect and certain elasticity. Because the sealing sleeve 22 is sandwiched between the inner ring shell 211 and the atomizer seat 13, it ensures the tight connection between the mist guide channel 13a and the mist outlet channel 211a. Therefore, the aerosol formed by the atomization core 12 flows entirely from the mist guide channel 13a into the mist outlet channel 211a and then out of the mouthpiece 211b, preventing aerosol from leaking out of other locations and causing waste.

[0173] In one embodiment, referring to FIG3 , the replacement assembly 2 further includes a sealing ring 25 , which is sandwiched between the outer circumferential wall of the housing 21 and the inner circumferential wall of the assembly groove 11a. Specifically, the sealing ring 25 is an annular ring that fits between the outer circumferential wall of the outer ring housing 212 and the inner circumferential wall of the annular sleeve 111 to provide a seal therebetween. The material of the sealing ring 25 is not particularly limited, and includes, but is not limited to, flexible sealing materials such as rubber and silicone that have good sealing properties and a certain degree of elasticity. In this embodiment, to facilitate assembly of the sealing ring 25 on the housing 21, a positioning groove 212a is formed on the outer circumferential wall of the outer ring housing 212. The positioning groove 212a is an annular groove formed in the opening of the annular sleeve 111 and adapted to the shape of the sealing ring 25. The sealing ring 25 is disposed within the positioning groove 212a.

[0174] In one embodiment, please refer to Figures 2 and 3, a further measuring chamber 21a is formed between the inner ring shell 211 and the outer ring shell 212. Specifically, the further measuring chamber 21a is formed by the outer peripheral wall of the inner ring shell 211 and the inner peripheral wall of the outer ring shell 212. The electronic atomization device 100 also includes a conducting structure 3 provided on the atomization bracket 11 or the replacement component 2, and the further measuring chamber 21a can be connected to the accommodating groove 11b through the conducting structure 3. As shown in Figure 3, in this embodiment, the conducting structure 3 is provided on the partition plate 112, and the conducting structure 3 can achieve conduction between the further measuring chamber 21a and the accommodating groove 11b under certain conditions.

[0175] In the related art, the liquid storage tank of the electronic atomizer device 100 has limited storage space. When a cotton wick is used to store liquid in the liquid storage tank, the cotton wick itself has a certain volume, which will reduce the liquid output of the liquid storage tank to a certain extent. At the same time, to prevent the cotton wick from leaking, the wick's liquid storage cannot reach 100% saturation, resulting in a small overall liquid storage capacity in the liquid storage tank. Furthermore, when the cotton wick's liquid storage capacity remains at 20%, the atomization consistency of the atomized medium decreases significantly, producing a burnt odor. Therefore, with limited storage space in the liquid storage tank, existing electronic atomizer devices have a short service life, a small number of suction ports, and low atomization medium utilization. In this embodiment, by providing a metering chamber 21a within the housing 21 to accommodate the atomized medium, the atomized medium in the metering chamber 21a can flow into the receiving tank 11b through the conductive structure 3. Given the limited space in the receiving tank 11b, the housing 21 with the metering chamber 21a can continuously supply liquid to the receiving tank 11b, ensuring the saturation of the cotton wick in the receiving tank 11b at all times. The consistency of the atomization of the electronic atomization device 100 will not decay, the use time of the electronic atomization device 100 is longer, the number of puffs is more, and the utilization rate of the electronic atomization device 100 is improved. Moreover, when the atomization medium in the receiving tank 11b is about to be used up, the atomization medium is injected into the metering chamber 21a, so that the atomization medium in the metering chamber 21a will not come into contact with the atomization core 12 too early, thereby maintaining the freshness of the atomization medium in the metering chamber 21a and improving the quality of the aerosol produced by atomization. In addition, it is also possible to directly replace it with a replacement component that stores the atomization medium in the metering chamber 21a, so that the atomization medium in the receiving tank 11b can be replenished after it is used up, and the atomization core 12 can be reused. The storage form of the atomization medium in the metering chamber 21a is not particularly limited. In one embodiment, the metering chamber 21a is provided with a cotton core, and the atomization medium is stored by the cotton core. The cotton core has a good effect in absorbing the atomization medium and is not prone to leakage of the atomization medium. In another embodiment, the cotton core can also be omitted, that is, the atomizing medium is directly stored in the metering chamber 21a. This arrangement can increase the liquid storage capacity of the metering chamber 21a, extend the service life of the electronic atomization device 100, and increase the number of puffs.

[0176] The structure of the conducting structure 3 is not particularly limited. In one embodiment, the conducting structure 3 is a regulating valve, which can adjust the amount of liquid flowing from the metering chamber 21a into the containing tank 11b according to the remaining liquid storage amount in the containing tank 11b, so as to achieve continuous liquid supply to the containing tank 11b.

[0177] In one embodiment, the conducting structure 3 is a one-way pump that only allows the atomized medium in the after-dosing chamber 21a to flow into the receiving tank 11b. By compressing the volume of the after-dosing chamber 21a, the one-way pump is activated, and the atomized medium in the after-dosing chamber 21a is introduced into the receiving tank 11b through the one-way pump, thereby achieving a continuous liquid supply to the receiving tank 11b.

[0178] In one embodiment, the conductive structure 3 is a consumable component that blocks the further metering chamber 21a from the receiving tank 11b. The consumable component can undergo a phase change under certain physical conditions to connect the further metering chamber 21a with the receiving tank 11b. For example, the consumable component is a hot melt medium, such as a gel. The gel is solid at room temperature, such as 25°C. When heated to a melting temperature, such as 50°C to 70°C, the gel liquefies, connecting the further metering chamber 21a to the receiving tank 11b.

[0179] Please refer to Figures 4 and 5. The structure of the electronic atomization device 100 of another embodiment of the present application is relatively similar to that of the electronic atomization device 100 shown in Figures 2 to 3. The difference is that the replacement component 2 includes a sealing cover 23 covering the opening of the refilling chamber 21a. The conductive structure 3 includes a piercing member 31 provided on the partition plate 112. In the process of installing the replacement component 2 from top to bottom into the assembly tank 11a, the piercing member 31 can abut against the sealing cover 23 and pierce the sealing cover 23, so that the atomized medium in the refilling chamber 21a can flow into the receiving tank 11b through the guide channel 31c, so as to achieve continuous liquid supply to the receiving tank 11b.

[0180] 5 , the sealing cover 23 includes an outer ring sleeve 231, an inner ring sleeve 232, and an annular cover plate 233 connected between the inner ring sleeve 232 and the outer ring sleeve 231. The outer ring sleeve 231 is located on the outer periphery of the inner ring sleeve 232, and the outer ring sleeve 231 is sealed and sleeved with the outer ring shell 212.

[0181] In one embodiment, as shown in Figures 5 and 19 , an outwardly protruding latch 2121 is formed on the outer circumferential wall of the outer ring housing 212. An insertion hole 231a is formed on the outer ring sleeve 231, and the latch 2121 snaps into the insertion hole 231a. This prevents the sealing cover 23 from falling off the outer ring housing 212, providing a high degree of sealing reliability.

[0182] The inner ring sleeve 232 is sandwiched between the inner ring shell 211 and the partition plate 112. In one embodiment, as shown in Figure 5, the outer peripheral wall of the inner ring shell 211 is formed with a stepped surface 211d facing the partition plate 112. One end of the inner ring sleeve 232 abuts against the stepped surface 211d, while the other end of the inner ring sleeve 232 is sandwiched between the outer peripheral wall of the inner ring shell 211 and the peripheral side wall of the atomizer seat 13. The stepped surface 211d facilitates the installation and fixation of the inner ring sleeve 232.

[0183] The piercing member 31 can penetrate the annular cover plate 233 to achieve continuous liquid supply from the continuous measuring chamber 21a to the containing groove 11b.

[0184] In one embodiment, the outer ring sleeve 231, the inner ring sleeve 232, and the annular cover plate 233 are integrally formed, thereby improving the overall sealing performance of the sealing cover 23. It is understood that in other embodiments, the outer ring sleeve 231 can be sleeved on the inner side or the outer side of the outer ring shell 212. Similarly, the inner ring sleeve 232 can be sleeved on the inner side or the outer side of the inner ring shell 211.

[0185] The sealing cover 23 is made of, but not limited to, a flexible sealing material such as rubber or silicone that has good sealing properties and a certain degree of elasticity. Thus, the sealing cover 23 can seal both the metering chamber 21a and the assembly slot 11a, thereby reducing the number of components in the replacement assembly 2 and simplifying assembly.

[0186] Referring to Figure 3 , the piercing member 31 is formed with a piercing opening 31a, an outlet 31b, and a flow guide channel 31c. The outlet 31b communicates with the receiving tank 11b, and the flow guide channel 31c connects the piercing opening 31a and the outlet 31b. Referring to Figure 5 , the portion of the annular cover plate 233 corresponding to the piercing opening 31a is relatively thin. During the downward installation of the replacement assembly 2 into the assembly tank 11a, the piercing member 31 can abut against the thinner portion of the annular cover plate 233, separating this portion from the rest of the annular cover plate 233, thereby connecting the refill chamber 21a to the receiving tank 11b. As shown in Figure 3 , the piercing member 31 is a syringe-like structure extending in the vertical direction. The upper end of the piercing member 31 forms the piercing opening 31a, the lower end forms the flow guide channel 31c, and the interior of the syringe-like structure forms the flow guide channel 31c.

[0187] In this embodiment, the piercing member 31 is integrally formed with the partition plate 112, ensuring a secure connection and high structural strength. It is understood that, in another embodiment, the piercing member 31 may also be disposed on the sealing cover 23 of the replacement assembly 2. During the downward installation of the replacement assembly 2 into the assembly tank 11a, the piercing member 31 can pierce the partition plate 112, allowing the atomized medium in the refill chamber 21a to flow through the guide channel 31c into the receiving tank 11b, thereby ensuring a continuous supply of liquid to the receiving tank 11b. Of course, in another embodiment, the piercing member 31 may also be disposed on both the partition plate 112 and the sealing cover 23. During the downward installation of the replacement assembly 2 into the assembly tank 11a, the piercing member 31 can simultaneously pierce the sealing cover 23 and the partition plate 112, ensuring a continuous supply of liquid from the refill chamber 21a to the receiving tank 11b.

[0188] In one embodiment, referring to Figures 3 and 5 , the conducting structure 3 further includes a liquid guide 4 disposed within the flow channel 31c to adjust the liquid flow rate. Specifically, the liquid guide 4 may include, but is not limited to, cotton, porous ceramics, fiber rope, or other porous materials. By adjusting the porosity of the liquid guide 4, the liquid supply rate to the continuous metering chamber 21a can be adjusted. Furthermore, the liquid guide 4 prevents the liquid medium within the receiving tank 11b from leaking when the replacement assembly 2 is disassembled.

[0189] Please refer to FIG. 6 to FIG. 8 . The electronic atomization device 100 of another embodiment of the present application is similar in structure to the electronic atomization device 100 shown in FIG. 4 to FIG. 5 . The difference is that the replacement component 2 further includes a packaging member 24 .

[0190] Please refer to Figure 7, the wrapping member 24 is coated on the side of the annular cover plate 233 away from the metering chamber 21a and the outer peripheral side of the outer ring sleeve 231. Specifically, the wrapping member 24 is coated on the lower end surface of the annular cover plate 233 and the outer peripheral wall of the outer ring sleeve 231. The wrapping member 24 is formed with at least one avoidance hole for avoiding interference when the replacement component 2 is installed in the assembly groove 11a. In this embodiment, the at least one avoidance hole includes a first avoidance hole corresponding to the piercing member 31, a second avoidance hole corresponding to the portion of the inner ring sleeve 232 extending into the atomizer seat 13, and a third avoidance hole corresponding to the pin 2121 of the outer ring shell 212.

[0191] The wrapping member 24 can restrain and secure the connection between the sealing cover 23 and the housing 21. The material of the wrapping member 24 is not particularly limited. For example, the wrapping member 24 can be made of a common cold-rolled steel plate (SPCC) to improve the securing and covering effect of the sealing cover 23.

[0192] In one embodiment, referring to Figures 7 and 8 , the replacement assembly 2 is formed with a ventilation channel 211c connecting the metering chamber 21a and the mist guide channel 13a. As the metering chamber 21a continuously supplies atomized medium to the receiving tank 11b, the atomized medium in the metering chamber 21a gradually decreases. The ventilation channel 211c replenishes the air in the mist guide channel 13a into the metering chamber 21a, balancing the air pressure in the metering chamber 21a with the external air pressure, ensuring that the atomized medium in the metering chamber 21a can be smoothly introduced into the receiving tank 11b.

[0193] The location of the ventilation channel 211c is not particularly limited. The ventilation channel 211c can be a channel located within the inner ring shell 211 or the sealing cover 23, or it can be a groove-shaped structure located on the outer peripheral wall of the inner ring shell 211 or the sealing cover 23. For example, in one embodiment, referring to FIG8 , the ventilation channel 211c is a ventilation groove formed by an inwardly recessed portion of the outer peripheral wall of the inner ring shell 211. This arrangement simplifies the molding process of the ventilation channel 211c. Specifically, a ventilation groove is formed on the outer peripheral wall of the inner ring shell 211 on which the inner ring sleeve 232 is provided, and the opening of the ventilation groove faces the inner peripheral wall of the inner ring sleeve 232. The ventilation groove includes a first groove section 211ca extending in the up and down directions and a second groove section 211cb extending in a direction perpendicular to the up and down directions. The second groove section 211cb is located on the step surface 211d. The outer peripheries of the first groove section 211ca and the second groove section 211cb are both covered with the inner ring sleeve 232. The lower end of the first groove section 211ca is connected to the mist guide channel 13a, the upper end of the first groove section 211ca is connected to one end of the second groove section 211cb, and the other end of the second groove section 211cb is connected to the continuous metering chamber 21a.

[0194] Please refer to Figures 9 and 10. The electronic atomization device 100 of another embodiment of the present application is relatively similar in structure to the electronic atomization device 100 of the aforementioned embodiment, and includes an atomization component 1 and a replacement component 2. The atomization component 1 includes an atomization bracket 11, an atomization core 12 and an atomization seat 13. The difference is that there is no assembly groove in the atomization component 1, and the replacement component 2 is detachably connected to the atomization component 1 by being sleeved on the atomization seat 13. In addition, the replacement component 2 includes a sealing cover 23 covering the opening of the metering chamber 21a. The conducting structure 3 includes a puncturing member 31 provided on the partition plate 112. The conducting structure 3 also includes a first protective cap 31d provided on the puncturing member 31. The function of the first protective cap 31d is to prevent the smoke oil in the receiving groove 11b of the atomization component 1 from flowing out of the internal guide channel of the puncturing member 31. In addition, since the tip of the puncture member 31 is particularly sharp, in order to ensure the safety of the atomizer assembly 1, when the atomizer assembly 1 is sold or transported separately, a first protective cap 31d can be used to protect the puncture hole 31a at the upper end of the puncture member 31 to prevent people from accidentally touching the puncture member 31 and causing damage.

[0195] As shown in Figure 10, when the replacement assembly 2 needs to be installed in the atomizer assembly 1, the first protective cap 31d can be removed first, thereby exposing the piercing member 31. During the process of installing the replacement assembly 2 from top to bottom into the assembly tank 11a, the piercing member 31 can abut against and pierce the sealing cover 23, thereby allowing the atomized medium in the after-dosing chamber 21a to flow into the receiving tank 11b through the guide channel 31c, thereby achieving a continuous liquid supply to the receiving tank 11b.

[0196] Please refer to Figures 9 and 10 again. In this embodiment, the top of the atomizer seat 13 can be provided with a suction nozzle 13c that is connected to the mist guide channel 13a. The atomizer seat 13 is also provided with a second protective cap 13d for sealing the suction nozzle 13c. When it is necessary to install the replacement component 2 into the assembly groove 11a of the atomizer component 1, the second protective cap 13d can be removed first to keep the suction nozzle 13c unobstructed. In addition, since the suction nozzle 13c is provided on the atomizer component 1, the replacement component 2 can also be provided with no suction nozzle. In this case, the replacement component 2 can be a sealing structure that only serves as the metering chamber 21a. For example, the shape of the replacement component 2 can be an annular sleeve.

[0197] 11 to 14 , the electronic atomization device 100 of another embodiment of the present application is similar in structure to the electronic atomization device 100 of the aforementioned embodiment, except that the sealing cover 23 includes an annular cover plate 233 and a blocking member 234 provided on the annular cover plate 233 .

[0198] The annular cover plate 233 is provided with two diversion holes 233a corresponding to the piercing member 31. Referring to Figure 14 , the blocking member 234 comprises a main body 234a and two blocking portions 234b. The main body 234a is generally annular. The two blocking portions 234b are movably connected to the main body 234a via two cantilever arms 234c. The blocking portions 234b are shaped like plugs and completely seal the diversion holes 233a.

[0199] When the replacement assembly 2 is not mounted on the atomizer assembly 1 , the two blocking portions 234 b are respectively located in the two flow guide holes 233 a , thereby preventing the atomized medium in the refill chamber 21 a from flowing out of the flow guide holes 233 a .

[0200] During the installation of the replacement assembly 2 from top to bottom into the assembly tank 11a, the piercing member 31 can abut against the blocking portion 234b and further push the blocking portion 234b upward to disengage from the guide hole 233a, thereby allowing the atomized medium in the refill chamber 21a to flow into the receiving tank 11b through the guide hole 233a and the guide channel 31c, thereby ensuring a continuous supply of liquid to the receiving tank 11b. After the blocking portion 234b is separated from the guide hole 233a, since the blocking portion 234b is always connected to the main body 234a via the cantilever 234c, the blocking portion 234b will not move around in the refill chamber 21a and produce abnormal noise.

[0201] It is understood that in another embodiment, the blocking member 234 may include only the blocking portion 234b. The blocking portion 234b can block the diversion hole 233a and can also be separated from the diversion hole 233a under the action of the piercing member 31. In this case, the main body 234a can also be omitted.

[0202] Referring to Figures 15 to 17 , another embodiment of the electronic atomization device 100 of the present application has a similar structure to the electronic atomization device 100 of the aforementioned embodiment, differing in that a first latching protrusion 213 is formed on one of the outer circumferential wall of the casing 21 and the annular sleeve 111, while a first latching groove 11aa is formed on the other. In other words, when the outer circumferential wall of the casing 21 is provided with the first latching protrusion 213, the annular sleeve 111 is provided with the first latching groove 11aa; and when the outer circumferential wall of the casing 21 is provided with the first latching groove 11aa, the annular sleeve 111 is provided with the first latching protrusion 213. The first latching protrusion 213 and the first latching groove 11aa engage with each other.

[0203] As shown in FIG15 , in one embodiment, the first locking protrusion 213 is provided on the outer peripheral wall of the outer ring shell 212. As shown in FIG22 , the first locking groove 11aa is provided on the annular sleeve 111.

[0204] As shown in Figure 17 , both end faces of the first latching protrusion 213, facing toward and away from the sliding direction, are sloped surfaces a, forming an obtuse angle with the outer wall of the housing 21. The direction in which the outer ring housing 212 enters the assembly slot 11a from top to bottom in Figure 17 is defined as the sliding direction. The sloped surface a is planar and forms an obtuse angle α with the outer wall of the outer ring housing 212. This arrangement allows for seamless assembly and disassembly between the housing 21 and the atomizer support 11, particularly when replacing the housing 21 containing the refill chamber 21a storing the atomizing medium.

[0205] Referring to Figures 18 to 22 , another embodiment of the electronic atomization device 100 of the present application has a similar structure to the electronic atomization device 100 of the aforementioned embodiment, differing in that a second latching protrusion 214 is formed on one of the outer circumferential wall of the casing 21 and the annular sleeve 111, while a second latching groove 11ab is formed on the other. In other words, when the outer circumferential wall of the casing 21 is provided with the second latching protrusion 214, the annular sleeve 111 is provided with the second latching groove 11ab; when the outer circumferential wall of the casing 21 is provided with the second latching groove 11ab, the annular sleeve 111 is provided with the second latching protrusion 214. The second latching protrusion 214 and the second latching groove 11ab engage with each other.

[0206] Please refer to Figures 18 and 19. In this embodiment, the second latching protrusion 214 is provided on the outer peripheral wall of the outer ring shell 212. As shown in Figure 22, the second latching groove 11ab is provided on the annular sleeve 111, and the second latching protrusion 214 is engaged in the second latching groove 11ab.

[0207] As shown in Figure 20, the end surface of the second latching protrusion 214 facing the sliding direction is a sloped surface a, and the end surface of the second latching protrusion 214 facing away from the sliding direction is a stop surface b. The angle between the sloped surface a and the outer peripheral wall of the sleeve 21 is an obtuse angle, while the angle between the stop surface b and the outer peripheral wall of the sleeve 21 is a right angle or an acute angle. Assuming that the direction in which the outer ring shell 212 enters the assembly groove 11a from top to bottom in Figure 20 is the sliding direction, the sloped surface a is planar and forms an obtuse angle α with the outer peripheral wall of the outer ring shell 212, while the stop surface b is planar and forms a right angle β with the outer peripheral wall of the outer ring shell 212. Thus, the assembly between the sleeve 21 and the atomizer bracket 11 is a loose fit, making it relatively easy to install the sleeve 21 into the assembly groove 11a in the sliding direction. However, the disassembly between the sleeve 21 and the atomizer bracket 11 is a fixed fit, making it relatively difficult to remove the sleeve 21 from the assembly groove 11a in the direction opposite to the sliding direction. This makes it difficult to disassemble the housing 21 after assembly, especially when the housing 21 has a metering cavity 21a and needs to supply liquid to the receiving groove 11b, thereby ensuring a more reliable connection between the housing 21 and the assembly groove 11a.

[0208] Referring to Figure 2 , in one embodiment, the electronic atomization device 100 includes a power supply module 200 , which is used to power the atomization assembly 1 to provide the energy required for the atomization core 12 to heat the atomized medium. Specifically, the power supply module 200 is disposed at one end of the atomization bracket 11 near the receiving groove 11b .

[0209] In one embodiment, the power supply module 200 includes a battery 201, a control panel assembly 202 and a power supply bracket 203. The battery 201 and the control panel assembly 202 are both arranged on the power supply bracket 203. The power supply bracket 203 is used to fix and support the battery 201 and the control panel assembly 202. The battery 201 is used to provide electrical energy to the control panel assembly 202 and the heating element 121. The lower end of the annular sleeve 111 of the atomizer bracket 11 is socketed with the upper end of the power supply bracket 203. The atomizer assembly 1 includes a sealing plug 15 for closing the receiving groove 11b. The sealing plug 15 is sealingly sleeved at the opening of the receiving groove 11b away from the partition plate 112 to prevent the atomizing medium in the receiving groove 11b from penetrating into the power supply bracket 203.

[0210] In one embodiment, referring to FIG. 2 and FIG. 3 , the electronic atomization device 100 includes a housing 300 , and the atomization assembly 1 and the power supply module 200 are both disposed in the housing 300 to maintain the overall appearance of the electronic atomization device 100 .

[0211] In one embodiment, referring to Figure 2 , the gaps between the housing 300 and the battery 201, the gaps between the power supply bracket 203 and the sealing plug 15, and the gaps between the battery 201 and the power supply bracket 203 are all filled with absorbent members 204, such as absorbent cotton. The absorbent cotton further prevents the atomized medium in the receiving groove 11b from penetrating into the power supply module 200, thereby improving the operational reliability of the electronic atomization device 100.

[0212] In one embodiment, the connection method between the power supply bracket 203 and the atomizer bracket 11 is not limited. That is, the power supply bracket 203 and the atomizer bracket 11 can be integrally formed, or the power supply bracket 203 and the atomizer bracket 11 can be manufactured separately and then assembled and connected in a detachable manner.

[0213] In this application, the orientation or positional relationship of the "extension direction" is based on the orientation or positional relationship shown in FIG25. It should be understood that these orientation terms are only used to facilitate the description of this application and simplify the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting this application.

[0214] 23 and 24 , an electronic atomization device according to one embodiment includes a housing assembly 10 , an atomization assembly 20 , and a ventilation and pressure stabilization structure 30 .

[0215] The housing assembly 10 includes an outer shell 12 and an outlet pipe 11 having an outlet passage 10b. A liquid reservoir 10a (i.e., the continuous metering chamber 21a in FIG. 5 ) is formed between the outer shell 12 and the outlet pipe 11. Specifically, the liquid reservoir 10a is used to hold aerosolized liquids such as liquid medicine and tobacco oil. During inhalation, the aerosolized liquid in the liquid reservoir 10a is directed to the atomizer assembly 20, which heats the aerosolized liquid to form an aerosol for the user to inhale.

[0216] The air outlet channel 10b is a channel for the air flow in the housing assembly 10 to flow out. The housing assembly 10 has an air inlet. During the suction process, the air inlet and the air outlet channel 10b are connected to form an air flow path.

[0217] 25 , the atomizing assembly 20 is disposed within the housing assembly 10. The atomizing assembly 20 encloses the liquid storage tank 10a and has an atomizing channel 20a communicating with the air outlet channel 10b.

[0218] Specifically, the atomizer assembly 20 is used to atomize the atomized liquid from the liquid storage tank 10a into an aerosol. The atomizer channel 20a is located along the airflow path. During a user's inhalation, ambient air flows from the air inlet into the housing assembly 10, flows along the airflow path through the atomizer channel 20a, and exits through the air outlet channel 10b. The aerosol formed within the atomizer channel 20a can flow with the airflow for inhalation by the user.

[0219] The ventilation and pressure stabilizing structure 30 (i.e., the sealing sleeve 22 in FIG3 ) is connected to at least one of the atomizing assembly 20 and the air outlet pipe 11. The ventilation and pressure stabilizing structure 30 can form a stable ventilation resistance that hinders the flow of gas between the atomizing channel 20a and the liquid storage tank 10a, thereby preventing the liquid storage tank 10a from being directly connected to the atmosphere.

[0220] Specifically, referring to Figure 25 , the ventilation and pressure-stabilizing structure 30 includes an insertion portion 31 extending into the liquid reservoir 10a. The insertion portion 31 is sleeved onto the end of the outlet pipe 11 near the atomizer assembly 20. The insertion portion 31 and the outlet pipe 11 cooperate to form a ventilation resistance that hinders the flow of gas between the atomizer passage 20a and the liquid reservoir 10a. When the atomizer is in the ventilation state, a ventilation passage 10c is formed between the insertion portion 31 and the outlet pipe 11, connecting the liquid reservoir 10a and the atomizer passage 20a.

[0221] It should be noted that the atomized liquid in the liquid storage tank 10a flows to the atomizing assembly 20 for atomization, and is not achieved through the ventilation channel 10c. The ventilation channel 10c is only an air intake channel set up to balance the liquid storage tank 10a and the external air pressure.

[0222] Specifically, please refer to Figure 25. In some embodiments, the extension portion 31 and the air outlet pipe 11 are in contact with each other, and the ventilation channel 10c is formed only when the atomizer is in the ventilation state. The gas in the atomization channel 20a can overcome the ventilation resistance and flow along the ventilation channel 10c to the liquid storage tank 10a.

[0223] In some embodiments, there may always be a ventilation channel 10c between the insertion portion 31 and the air outlet pipe 11, but the ventilation channel 10c is connected to the atomizing channel 20a and the liquid storage tank 10a only when the atomizer is in the ventilation state, and when the atomizer is in other states (such as the suction process), the ventilation channel 10c is blocked to form a ventilation resistance. When the atomizer is in a non-ventilation state, such as during the suction process, the air flow in the atomizing channel 20a flows to the air outlet channel 10b, so that a negative pressure is formed in the atomizing channel 20a, and the atomized liquid in the liquid storage tank 10a flows to the atomizing assembly 20 for atomization. There is a ventilation resistance between the atomizing channel 20a and the liquid storage tank 10a, and thus no air flow exists.

[0224] When the suction action is completed, there is no airflow flowing through the atomizing channel 20a and normal pressure is restored. There is negative pressure in the liquid storage tank 10a due to the reduction of atomized liquid during the suction process. When the pressure difference reaches a certain level, the atomizer enters the ventilation state. The air in the atomizing channel 20a can overcome the ventilation resistance and flow along the ventilation channel 10c to the liquid storage tank 10a to balance the air pressure in the liquid storage tank 10a and the outside world.

[0225] It should be noted that no matter how the atomized liquid in the liquid storage bin 10a changes, the insertion portion 31 and the air outlet pipe 11 can cooperate to form a ventilation resistance. In other words, even if the atomized liquid in the liquid storage bin 10a is completely consumed, the insertion portion 31 and the air outlet pipe 11 can still cooperate to form a ventilation resistance.

[0226] Thus, by providing the extending portion 31, it is possible to ensure that there is always ventilation resistance between the liquid storage tank 10a and the atomizing channel 20a, so that the air in the atomizing channel 20a must overcome this ventilation resistance before it can flow into the liquid storage tank 10a. This prevents the liquid storage tank 10a from being directly connected to the atmosphere, thereby preventing excessive liquid supply per puff during the puffing process, thereby preventing problems such as smoke reduction and severe leakage.

[0227] In one embodiment, referring to Figure 25 , the extension portion 31 is spaced apart from the air outlet pipe 11, forming a capillary space 31d therebetween. Capillary space 31d constitutes at least a portion of the ventilation passage 10c. Capillary space 31d is connected to the liquid reservoir 10a. Atomized liquid within the liquid reservoir 10a can fill capillary space 31d under capillary action, creating ventilation resistance between the atomization passage 20a and the liquid reservoir 10a.

[0228] Specifically, the distance between the extending portion 31 and the air outlet pipe 11 is less than or equal to 1 mm, which can cause the atomized liquid in the liquid storage tank 10a to fill the capillary space 31d under the capillary action.

[0229] Therefore, even if the atomized liquid level in the liquid storage tank 10a drops below the top of the capillary space 31d, or even if it is completely consumed, the atomized liquid in the capillary space 31d will not easily flow out. Moreover, even if part of the atomized liquid in the capillary space 31d leaks out under special circumstances, the atomized liquid in the liquid storage tank 10a can be quickly replenished into the capillary space 31d. This ensures that the insertion portion 31 can cooperate with the air outlet pipe 11 to always form a ventilation resistance, thereby forming a stable ventilation resistance between the liquid storage tank 10a and the atomization channel 20a, so that the liquid storage tank 10a and the atomization channel 20a are not easily connected.

[0230] It is understandable that the capillary space 31d can be a part of the ventilation channel 10c or the entire area of ​​the ventilation channel 10c. When the atomizer is in the ventilation state, a ventilation path passing through the capillary space 31d is formed between the atomizing channel 20a and the liquid storage tank 10a.

[0231] It should be noted that the extending portion 31 may have only a portion of its area cooperating with the outlet pipe 11 to maintain a stable ventilation resistance, or the entire area may cooperate with the outlet pipe 11 to form ventilation resistance. The ventilation resistance depends on the capillary force between the capillary space 31d and the atomized liquid, and is therefore related to the material of the extending portion 31, the specific dimensions of the capillary space 31d, etc.

[0232] In one embodiment, referring to Figure 25 , the extending portion 31 has a first communication port 31a and a second communication port 31b at opposite ends along its extension direction. The first communication port 31a connects the atomizing channel 20a with the capillary space 31d, while the second communication port 31b connects the capillary space 31d with the liquid reservoir 10a. A liquid supply groove 31c (see Figure 28 ) is formed on the sidewall of the extending portion 31, connecting the liquid reservoir 10a with the capillary space 31d.

[0233] Specifically, when the atomizer is in the ventilation state, a ventilation path is formed between the atomizing channel 20a and the liquid storage tank 10a, passing through the first communication port 31a, the capillary space 31d, and the second communication port 31b. By forming the liquid supply groove 31c, the liquid storage tank 10a and the capillary space 31d are connected, and liquid can be continuously supplied to the capillary space 31d.

[0234] It should be noted that the specific shape, number and location of the liquid supply grooves 31 c are not limited, and they can be, for example, round holes or square holes.

[0235] Exemplarily, referring to FIG. 28 , the liquid supply groove 31 c is a strip-shaped groove extending along the extending direction of the extending portion 31 , and one end of the liquid supply groove 31 c along the extending direction is connected to the second communication port 31 b .

[0236] Specifically, one end of the liquid supply groove 31 c extends to the second communication port 31 b , and the other end may extend to the first communication port 31 a , or may not be connected to the first communication port 31 a .

[0237] In one embodiment, referring to FIG. 28 , two liquid supply grooves 31 c are formed on the side wall of the extending portion 31 . The two liquid supply grooves 31 c are staggered relative to the center of the air outlet pipe 11 .

[0238] Specifically, the two liquid supply grooves 31c are offset relative to the center of the air outlet pipe 11, meaning that the line connecting the two liquid supply grooves 31c does not pass through the center of the air outlet pipe 11, that is, the two are relatively offset. This prevents the atomized liquid in the capillary space 31d from easily leaking out of the liquid supply port 31c when the atomizer is placed on its side, thereby preventing the atomized liquid in the capillary space 31d from failing to block the atomized liquid.

[0239] In one embodiment, referring to Figures 26 and 27 , a ventilation groove 11a is formed on the outer surface of the end of the outlet pipe 11 near the atomizer assembly 20. This groove 11a forms part of the ventilation channel 10c. One end of the groove 11a communicates with the atomizer channel 20a, while the other end of the groove 11a extends to the insertion portion 31. When the atomizer is in the ventilation mode, the capillary space 31d communicates with the liquid reservoir 10a and the ventilation groove 11a, respectively.

[0240] Specifically, the ventilation channel 10c includes a ventilation groove 11a and a capillary space 31d. The extending portion 31 blocks the end of the ventilation groove 11a away from the atomizing assembly 20, so that ventilation resistance is formed between the atomizing channel 20a and the liquid storage tank 10a.

[0241] It should be noted that the side of the ventilation groove 11a has an opening facing the extension portion 31, and the extension portion 31 covers the opening. When the atomizer is in the non-ventilation state, the extension portion 31 blocks one end of the ventilation groove 11a. The other end of the ventilation groove 11a is connected to the atomization channel 20a, allowing the ventilation groove 11a to be filled with air. When the atomizer is in the ventilation state, gas can pass through the ventilation groove 11a to push the extension portion 31, separating at least a portion of the extension portion 31 from the outlet pipe 11.

[0242] That is to say, by providing the ventilation groove 11a, more air can be gathered, so that the force-bearing area of ​​the extension portion 31 is larger in the ventilation state, and the extension portion 31 can be opened more easily, thereby facilitating the air in the atomization channel 20a to push the extension portion 31 open.

[0243] In one embodiment, referring to FIG. 27 , the ventilation groove 11a includes a first sub-groove 11aa and a second sub-groove 11ab located at an end of the first sub-groove 11aa facing away from the atomizer assembly 20. Opposite ends of the first sub-groove 11aa along the extension direction are connected to the second sub-groove 11ab and the atomizer passage 20a, respectively. The cross-sectional area of ​​the first sub-groove 11aa is smaller than that of the second sub-groove 11ab. This reduces the size of the connection between the ventilation groove 11a and the atomizer passage 20a, preventing the atomized liquid in the liquid storage tank 10a from flowing out through the ventilation groove 11a into the atomizer passage 20a and causing leakage.

[0244] Referring to Figures 29 and 30, an atomizer according to another embodiment has a structure similar to that of the atomizer of the aforementioned embodiment, including a housing assembly 10, an atomizing assembly 20, and a ventilation and pressure-stabilizing structure 30. The difference is that in this embodiment, when the atomizer is in a non-ventilation state, at least a portion of the insertion portion 31 is in contact with the air outlet pipe 11 to separate the atomization channel 20a from the liquid storage tank 10a. When the atomizer is in a ventilation state, at least a portion of the insertion portion 31 is separated from the air outlet pipe 11 to form a ventilation channel 10c that connects the liquid storage tank 10a with the atomization channel 20a.

[0245] Specifically, depending on the actual situation, the entire area of ​​the extension portion 31 can be in contact with the outlet pipe 11, or only a portion of the area can be in contact with the outlet pipe 11. In addition, the contact between the extension portion 31 and the outlet pipe 11 does not mean that the two are inseparable. In fact, the extension portion 31 is in contact with the outlet pipe 11 in a detachable manner. In other words, when the atomizing channel 20a is at normal pressure and the liquid storage tank 10a is at negative pressure, the atomizer is in a ventilation state, and the air in the atomizing channel 20a can push the extension portion 31 to separate from the outlet pipe 11, thereby entering the liquid storage tank 10a through the ventilation channel 10c.

[0246] It should be noted that the size of the ventilation resistance formed by the contact between the extending portion 31 and the outlet pipe 11 and the size of the ventilation channel 10c can be determined according to actual conditions, which are related to the material properties of the extending portion 31 itself.

[0247] For example, when the insertion portion 31 is made of silicone, the distance between the insertion portion 31 and the air outlet pipe 11 in the ventilation channel 10c is greater than 0.2mm and less than 0.4mm, such as 0.3mm. Of course, the insertion portion 31 can also be made of plastic, steel plate or other materials.

[0248] The extension portion 31 and the air outlet pipe 11 may be separated only partially to form the ventilation channel 10c. Of course, according to actual conditions, the entire extension portion 31 may be separated from the air outlet pipe 11 to form the ventilation channel 10c.

[0249] When atomized liquid is stored in the liquid storage bin 10a, the atomized liquid can squeeze the insertion portion 31. Thus, when the atomizer is in a non-ventilated state (such as during suction), the insertion portion 31 and the air outlet pipe 11 can be more closely fitted to prevent leakage.

[0250] In another embodiment, an oil film seal may be formed between the extending portion 31 and the air outlet pipe 11 to improve the separation effect of the extending portion 31 on the atomization channel 20a and the liquid storage tank 10a, thereby achieving a better pressure stabilization effect.

[0251] In one embodiment, referring to FIG. 30 and FIG. 31 , the extending portion 31 includes two valve plates 311 detachably attached to opposite sides of the air outlet pipe 11 in the radial direction. The two valve plates 311 are opposite to each other and spaced apart.

[0252] Specifically, the two valve plates 311 are two elastic arc-shaped plates arranged on opposite sides of the outlet pipe 11. Thus, under the pushing effect of the airflow in the ventilation groove 11a, the two valve plates 311 can move away from each other, thereby separating from the outlet pipe 11.

[0253] In addition, the number of ventilation grooves 11a is not limited. A plurality of ventilation grooves 11a can be provided so that different valve plates 311 correspond to different ventilation grooves 11a. Of course, only one ventilation groove 11a can be provided to correspond to two valve plates 311 at the same time.

[0254] As shown in Figures 25 and 30, the atomizing assembly 20 includes a central tube (i.e., the atomizing seat 13 in Figure 3), an atomizing core and a liquid-absorbing cotton. The atomizing core and the liquid-absorbing cotton are arranged in the central tube. The liquid-absorbing cotton is located between the central tube and the air outlet pipe 11. The atomizing core has an atomizing chamber connected to the air inlet. The air outlet pipe 11 has a flow channel at both ends corresponding to the flow channel connecting the air outlet channel 10b and the atomizing chamber. The flow channel and the atomizing chamber together constitute at least a part of the atomizing channel 20a. The ventilation channel 10c is connected to the flow channel.

[0255] Another embodiment of the present application further provides an electronic atomization device, comprising a power supply assembly and the atomizer described in any of the above embodiments, wherein the power supply assembly is electrically connected to the atomization assembly 20.

[0256] Referring to Figures 32 to 34 , one embodiment of the present application provides an electronic atomization device that can be used to contain atomized liquids such as liquid medicine and e-liquid and atomize them to generate an aerosol for inhalation by the user. The electronic atomization device includes a housing assembly 10 and an atomization assembly 20. The housing assembly 10 has an air inlet, a guide channel 12a (see Figure 35 ) connected to the air inlet, and an outlet channel 10d having an air outlet 10e. The guide channel 12a and the outlet channel 10d are spaced apart.

[0257] The atomizing assembly 20 is disposed within the housing assembly 10 and is located between the flow guiding channel 12a and the air outlet channel 10d. The atomizing assembly 20 has an atomizing channel 20a. The end surfaces of the atomizing assembly 20 at opposite ends contact the housing assembly 10 so that the atomizing channel 20a is connected to the air outlet channel 10d and the flow guiding channel 12a, respectively. An air flow path including the flow guiding channel 12a, the atomizing channel 20a, and the air outlet channel 10d is formed between the air inlet and the air outlet. A liquid guide path including the atomizing channel 20a is formed between the air outlet channel 10d and the flow guiding channel 12a.

[0258] The above-mentioned electronic atomization device includes a shell assembly 10 and an atomization assembly 20. An air flow path is formed between the air inlet and the air outlet 10e of the shell assembly 10, passing through at least the guide channel 12a, the atomization channel 20a and the air outlet channel 10d. A liquid guide path is formed between the air outlet channel 10d and the guide channel 12a, passing through the atomization channel 20a. The end faces at opposite ends of the atomization assembly 20 are in contact with the shell assembly 10, so that the atomization channel 20a is connected to the air outlet channel 10d and the guide channel 12a respectively. As a result, no step surface is formed between the two ends of the atomization assembly 20 and the shell assembly 10, so that the leaked liquid can flow along the liquid guide path, thereby preventing the leaked liquid from converging at the two ends of the atomization assembly 20, thereby preventing the electronic atomization device from producing a gurgling sound when the user inhales, thereby improving the user experience.

[0259] The air inlet is used to allow ambient air to flow into the housing assembly 10. During inhalation, air flows from the air inlet into the housing assembly 10, along the airflow path, through the atomization channel 20a and the air outlet channel 10d, and out through the air outlet 10e. The aerosol formed in the atomization channel 20a can flow with the airflow for inhalation by the user.

[0260] The size of the atomization channel 20a significantly impacts the user's puff experience. In one embodiment, the inner diameter of the atomization channel 20a is greater than 2.2 mm and no greater than 2.5 mm. Preferably, the inner diameter of the atomization channel 20a is 2.3 mm, 2.4 mm, or 2.5 mm. The inner diameter of the atomization channel 20a should not exceed 2.5 mm to avoid compromising the user's puff experience. The inner diameter of the atomization channel 20a should also not be too small to prevent leaked liquid from flowing along the liquid guide path.

[0261] It should be noted that one end of the atomizer assembly 20 contacts the area of ​​the housing assembly 10 having the air outlet channel 10d, thereby connecting the atomizer channel 20a to the air outlet channel 10d. The other end of the atomizer assembly 20 contacts the area of ​​the housing assembly 10 having the flow guide channel 12a, thereby connecting the atomizer channel 20a to the flow guide channel 12a. In this way, a continuous channel can be formed for leaked liquid to flow along the liquid guide path.

[0262] The specific structure of the atomizing assembly 20 is not limited and can be set according to actual conditions.

[0263] Referring to Figure 35 , in this embodiment, the atomizer assembly 20 includes a first flow guide 21 having a first channel 21a and an atomizer core 22 having a second channel 22a. The first channel 21a and the second channel 22a together constitute a portion of the atomizer channel 20a. Opposite end surfaces of the first flow guide 21 respectively contact the atomizer core 22 and the housing assembly 10, allowing the second channel 22a to communicate with the outlet channel 10d through the first channel 21a.

[0264] Specifically, the second channel 22a, the first channel 21a, and the outlet channel 10d are continuous. The atomizer core 22 is a structure in the atomizer assembly 20 used to heat the atomized liquid. By providing the first flow guide 21 between the atomizer core 22 and the outlet channel 10d, the atomizer core 22 and the outlet channel 10d are isolated from each other to prevent the atomizer core 22 from overheating and damaging the outlet channel 10d. Furthermore, the specific dimensions of the second channel 22a, the first channel 21a, and the outlet channel 10d can be set according to actual conditions.

[0265] It should be noted that the inner walls of the air outlet channel 10d, the atomizing channel 20a and the guide channel 12a are continuously arranged, and no step surface is formed at the connection between the two, so the guide effect can be further improved to prevent the leakage from converging. In other embodiments, there may be a narrow gap between the end faces of the atomizing component 20 and the shell component 10, or a smaller step surface may be formed between the inner walls of the channel, but the narrow gap and the smaller step surface do not affect the leakage flowing along the guide path. For example, due to errors in actual production, there is a smaller gap or step surface at the junction of the atomizing component 20 and the shell component 10, but in actual use, the gap or step surface cannot cause the leakage to converge here, and does not affect the leakage flowing along the guide path.

[0266] In one embodiment, the inner wall of the first channel 21a is coplanar with the inner wall of the second channel 22a and the inner wall of the outlet channel 10d. In other words, the first channel 21a, the second channel 22a, and the outlet channel 10d have the same dimensions at their junctions, and the transition between the three can be smooth.

[0267] The first channel 21 a and the second channel 22 a together constitute a portion of the atomization channel 20 a . That is, the atomization channel 20 a may only include the first channel 21 a and the second channel 22 a , and may also include other channels.

[0268] Referring to Figure 35, the atomizer assembly 20 also includes a sealing plug 24 disposed on the side of the atomizer core 22 facing away from the first flow guide 21 and used to seal the flow guide chamber 10f. The sealing plug 24 has a third channel 24a. The opposite ends of the sealing plug 24 are in contact with the atomizer core 22 and the bracket assembly 12, respectively, so that the flow guide channel 12a is connected to the second channel 22a through the third channel 24a. The first channel 21a, the second channel 22a, and the third channel 24a together constitute the atomizer channel 20a. There is no step between the opposite ends of the sealing plug 24 and the atomizer core 22 and the bracket assembly 12, so that the inner walls of the flow guide channel 12a, the third channel 24a, and the second channel 22a are continuously arranged. The sealing plug 24 can be a silicone cover.

[0269] The specific dimensions of the diversion channel 12a and the third channel 24a can be set according to actual conditions. For example, the inner wall of the diversion channel 12a and the inner wall of the third channel 24a can be coplanar. In other words, the walls of the diversion channel 12a and the third channel 24a have the same dimensions at least where they meet, allowing for a smooth transition.

[0270] In one embodiment, referring to Figures 34 and 35 , the housing assembly 10 includes a shell 11 and a bracket assembly 12 having a fluid guide channel 12a. The bracket assembly 12 is disposed within the shell 11. The housing assembly 10 also includes a liquid suction chamber 10a located on one side of the bracket assembly 12. The end of the fluid guide channel 12a facing away from the third channel 24a is connected to the liquid suction chamber 10a, so that the fluid guide path extends into the liquid suction chamber 10a.

[0271] Specifically, the liquid suction chamber 10a is used to accommodate and absorb liquid leakage from the ventilation channel 10c and the atomization channel 20a. The atomization channel 20a is connected to the liquid suction chamber 10a via the diversion channel 12a. As a result, the leaked liquid in the atomization channel 20a can flow along the liquid diversion path and flow into the liquid suction chamber 10a through the diversion channel 12a.

[0272] The specific location of the liquid absorption chamber 10a is not limited. In this embodiment, the liquid absorption chamber 10a is a battery chamber, which is used to place the battery of the electronic atomization device and the liquid absorption cotton, wherein the liquid absorption cotton is used to absorb and store the leaked liquid flowing along the liquid guide path.

[0273] In one embodiment, referring to Figure 38 , the bracket assembly 12 includes a bracket 121 and a second air guide 122. The bracket 121 defines an air passage cavity 121a (see Figure 35 ), and the second air guide 122 is disposed within the air passage cavity 121a. A flow channel 12a is disposed within the second air guide 122, and the air passage cavity 121a and the flow channel 12a constitute a portion of the air flow path.

[0274] Specifically, the external airflow flowing in from the air inlet flows along the air flow path in sequence through the air cavity 121a, the guide channel 12a, the atomization channel 20a and the air outlet channel 10d, and flows out from the air outlet 10e of the air outlet channel 10d.

[0275] The air passage cavity 121a facilitates the flow of air from the air outlet 10e into the flow guide channel 12a. No absorbent cotton is required in the air passage cavity 121a to prevent the absorbent cotton from obstructing the flow of air, thereby ensuring that the bracket assembly 12 has sufficient space for gas exchange.

[0276] In some embodiments, while ensuring the flow effect of the air flow, absorbent cotton can be arranged in the air cavity 121a to absorb the leaked liquid flowing along the guide path.

[0277] 38 , in this embodiment, the second flow guide 122 includes two flow guide columns 1221 spaced apart within the air cavity 121a, with the flow channel 12a formed at the interval between the two flow guide columns 1221. The shape of the flow guide columns 1221 significantly affects the flow guiding effect of the flow channel 12a.

[0278] In this embodiment, the surfaces of the two guide posts 1221 on the side close to each other are continuously arranged with the inner wall of the atomization channel 20a. The above continuous arrangement means that they are continuous along the extension direction of the liquid guide path.

[0279] In one embodiment, referring to Figure 34 , the housing assembly 10 includes a liquid storage tank 10b (i.e., the metering chamber 21a in Figure 5 ) and a flow guide chamber 10f (i.e., the receiving groove 11b in Figure 5 ) communicating with the liquid storage tank 10b . A sealing plug 24 is used to seal the flow guide chamber 10f . The electronic atomization device also includes a first liquid guide cotton 30 disposed within the flow guide chamber 10f . The housing assembly 10 also includes a mounting chamber 30a for mounting the atomizer core 22 .

[0280] Specifically, the liquid storage tank 10b is a structure for storing atomized liquids such as liquid medicine and tobacco oil in the electronic atomization device. During the user's inhalation process, the atomized liquid in the liquid storage tank 10b can be guided to the atomization assembly 20 for the atomization assembly 20 to heat the atomized liquid to atomize and form an aerosol.

[0281] During the user's inhalation process, the atomizer core 22 can atomize the atomized liquid, and the first liquid guiding cotton 30 can continuously guide the atomized liquid from the liquid storage tank 10 b to the atomizer core 22 .

[0282] In one embodiment, referring to Figures 34 to 37, the housing assembly 10 further includes a ventilation channel 10c, through which the liquid storage tank 10b is connected to the first channel 21a. The ventilation channel 10c has a ventilation inlet 10ca connected to the first channel 21a, and a ventilation outlet 10cb connected to the liquid storage tank 10b. The distance between the ventilation outlet 10cb and the central cross-section of the liquid storage tank 10b is a first spacing, and the distance between the connection point between the liquid storage tank 10b and the diversion cavity 10f and the central cross-section is a second spacing, and the first spacing is not less than the second spacing. It should be noted that the central cross-section of the liquid storage tank 10b refers to the plane corresponding to the cross-section of the liquid storage tank 10b passing through the center point. Taking this central cross-section as a reference, the distance between the ventilation outlet 10cb and it should be greater than or equal to the distance between the connection point between the liquid storage tank 10b and the diversion cavity 10f and it.

[0283] Specifically, the atomized liquid in the liquid storage tank 10b flows to the atomizing assembly 20 for atomization, and this is not achieved through the ventilation channel 10c. The ventilation channel 10c is only a channel provided for balancing the liquid storage tank 10b and the external air pressure. In one embodiment, one end of the ventilation channel 10c is connected to the liquid storage tank 10b, and the other end is connected to the atmosphere. For example, the ventilation channel 10c is connected to the atomizing channel 20a or the air outlet channel 10d. When the user inhales, part of the atomized liquid in the liquid storage tank 10b will leak out through the ventilation channel 10c. At the same time, the atomized liquid that flows to the atomizing assembly 20 for heating and atomization will also leak into the atomizing channel 20a. Therefore, by setting a liquid guide path, the leaked liquid at both places can be diverted to the liquid suction tank 10a, thereby achieving the purpose of preventing leakage.

[0284] On the other hand, the first flow guide 21 can play a flow guiding role, and can guide the atomized liquid leaking out of the ventilation channel 10c into the first channel 21a to flow along the liquid guide path.

[0285] When the electronic atomizer device is in use or placed vertically, the height of the ventilation outlet 10cb from the ground is greater than the height from the ground of the connection point between the liquid storage tank 10b and the diversion cavity 10f. It should be noted that when the liquid level of the atomized liquid in the liquid storage tank 10b is consumed below the ventilation outlet 10cb, the ventilation outlet 10cb is directly connected to the cavity in the liquid storage tank 10b, causing the liquid storage tank 10b to be directly connected to the outside world. The atomized liquid in the liquid storage tank 10b continues to flow to the atomizer assembly 20 under the action of gravity, thereby causing serious leakage problems. By forming a height difference between the connection point between the liquid storage tank 10b and the diversion cavity 10f and the ventilation outlet 10cb, it can be ensured that the atomized liquid in the liquid storage tank 10b is always located in the atomized liquid before it is completely consumed, and there is negative pressure in the cavity in the liquid storage tank 10b, thereby avoiding serious leakage from the atomizer assembly 20.

[0286] Referring to Figure 40, the first flow guide 21 includes a third liquid-conducting cotton 211 having a first channel 21a. The shape of the third liquid-conducting cotton 211 is roughly C-shaped. Part of the area of ​​the third liquid-conducting cotton 211 is interrupted to form a flow port 21b, and the flow port 21b is connected to the first channel 21a and the ventilation channel 10c respectively. Therefore, when the electronic atomization device is ventilated through the ventilation channel 10c, the gas in the first channel 21a can enter the ventilation channel 10c through the flow port 21b and flow into the liquid storage tank 10b along the ventilation channel 10c.

[0287] Please refer to Figure 39. The atomizer assembly 20 includes a tube body 23, and the atomizer core 22 is arranged in the tube body 23. Part of the area of ​​the tube body 23 is opened to form a flow groove 23a, so that the atomized liquid of the first liquid-conducting cotton 30 flows to the atomizer core 22 through the flow groove 23a. The tube body 23 can play a role in limiting the supply amount of the atomized liquid flowing to the atomizer core 22. Specifically, the cross-sectional area of ​​the flow groove 23a satisfies that the supply amount of the atomized liquid flowing to the atomizer core 22 is not greater than the atomization amount of the atomizer core 22. By reasonably setting the cross-sectional area of ​​the flow groove 23a, the liquid supply amount per mouth per unit time of the atomized liquid flowing from the liquid storage tank 10b to the atomizer assembly 20 through the first liquid-conducting cotton 30 can be controlled, thereby reducing the amount of leakage in the atomizer channel 20a.

[0288] It is understandable that when the supply amount of atomized liquid flowing to the atomizer core 22 is not greater than the atomization amount of the atomizer core 22, the leakage amount in the atomization channel 20a can be greatly reduced, thereby reducing the accumulation of leakage and preventing the generation of gurgling sounds, thereby improving the user experience.

[0289] Of course, the amount of atomized liquid flowing to the atomizer core 22 cannot be too low and should meet the user's inhalation needs. For example, the amount of atomized liquid flowing to the atomizer core 22 can be equal to the atomization amount of the atomizer core 22.

[0290] In one embodiment, the atomizer assembly 20 is located at the bottom of the air outlet channel 10d, the bracket assembly 12 is located at the bottom of the atomizer assembly 20, and the liquid suction chamber 10a is located at the bottom of the flow channel 12a. The liquid flow path extends from top to bottom, and the air flow path extends from bottom to top.

[0291] 35 , the atomizer core 22 includes a heating element 221 and a second liquid-conducting sponge 222 having a second channel 22a. The heating element 221 is disposed within the second channel 22a. Specifically, the type of the heating element 221 is not limited, and it can be a heating sheet disposed on the inner wall of the second channel 22a.

[0292] Referring to Figures 41, 42, 44, and 45, an embodiment of the present application provides a power supply assembly for an electronic atomization device. The power supply assembly includes a housing assembly 10 and a microphone 40. The housing assembly 10 has an air inlet 10a and an air outlet 10b, and an air flow path is formed between the air inlet 10a and the air outlet 10b. The air flow path is a channel for air flow between the air inlet 10a and the air outlet 10b. The external air flow flows in from the air inlet 10a, flows along the air flow path, and finally flows out from the air outlet 10b.

[0293] As shown in FIG45 , the microphone 40 is disposed within the housing assembly 10. The microphone 40 has a normal pressure sensing surface 40b and a negative pressure sensing surface 40a. The normal pressure sensing surface 40b is used to sense atmospheric pressure, while the negative pressure sensing surface 40a is used to sense negative pressure within the airflow path. The method by which the normal pressure sensing surface 40b senses atmospheric pressure is not limited, as long as the normal pressure sensing surface 40b maintains normal pressure. For example, at least a portion of the normal pressure sensing surface 40b is connected to the airflow path, that is, the normal pressure sensing surface 40b is connected to the outside of the housing assembly 10 by connecting to the airflow path. Of course, in addition to connecting to the airflow path, the normal pressure sensing surface 40b can also connect to the outside of the housing assembly 10 through other openings. For example, the housing assembly 10 further includes a through hole that connects to the normal pressure sensing surface 40b. The normal pressure sensing surface 40b connects to the outside of the housing assembly 10 through this through hole.

[0294] During the suction process, negative pressure is formed on the negative pressure sensing surface 40a of the microphone 40, while the normal pressure sensing surface 40b of the microphone 40 is connected to the outside of the shell assembly 10 and can maintain normal pressure. The microphone 40 is activated by sensing the pressure difference on both sides.

[0295] It should be noted that, as shown in Figure 44 , the angle γ between the normal direction α of the negative pressure sensing surface 40a and the extension direction β of the air outlet 10b is greater than 90° and less than or equal to 180°. The normal direction α of the negative pressure sensing surface 40a refers to the direction perpendicular to the negative pressure sensing surface 40a. In one embodiment, the angle γ is equal to 180°, meaning that the negative pressure sensing surface 40a is disposed opposite the air outlet 10b.

[0296] When the electronic atomizer device is placed vertically, the external airflow will move toward the air outlet 10b. Since the negative pressure sensing surface 40a is located on the side of the microphone 40 away from the air outlet 10b, and the normal pressure sensing surface 40b is located on the side of the microphone 40 close to the air outlet 10b, that is, on the leeward side of the microphone, the external airflow will not impact the normal pressure sensing surface 40b in the opposite direction, so that the microphone 40 will only be activated due to the pressure difference formed between the negative pressure sensing surface 40a and the normal pressure sensing surface 40b during the suction process. Therefore, it can avoid the situation where the microphone 40 is easily activated due to the direct impact of the external airflow when the normal pressure sensing surface 40b of the microphone 40 is away from the side of the air outlet 10, thereby avoiding the accidental activation of the microphone 40.

[0297] Referring to Figures 42, 43, and 45, the power supply assembly further includes a bracket assembly 20 disposed within the housing assembly 10. Bracket assembly 20 defines a microphone mounting cavity 20c, within which a microphone 40 is mounted. The area of ​​microphone mounting cavity 20c located to the side of negative pressure sensing surface 40a communicates with the airflow path. Referring to Figure 44, the housing assembly 10 further includes a bottom cover 11. An air inlet 10a is defined within bottom cover 11. Bottom cover 11 encloses microphone mounting cavity 20c and is spaced apart from negative pressure sensing surface 40a.

[0298] The bottom cover 11 is located on the side of the microphone mounting cavity 20c facing away from the air outlet 10b. This ensures that the microphone mounting cavity 20c maintains a good seal in addition to being in communication with the airflow path. Specifically, the microphone mounting cavity 20c is in communication only with the airflow path. When a user inhales through the air outlet 10b, the suction at the air outlet 10b creates a negative pressure in the area of ​​the microphone mounting cavity 20c on the side of the negative pressure sensing surface 40a.

[0299] In this embodiment, the microphone 40 is not mounted on the bottom cover 11, but is spaced apart from the bottom cover 11. This increases the space between the microphone 40 and the bottom cover 11, preventing liquid in the airflow path from entering the microphone mounting cavity 20c and damaging the microphone 40, thereby preventing the microphone 40 from failing.

[0300] In addition, a liquid absorption structure may be provided on the bottom cover 11 to absorb or lock the liquid that enters the microphone mounting cavity 20c.

[0301] Referring to Figures 52 and 53 , the portion of the bottom cover 11 located within the microphone mounting cavity 20c forms a liquid reservoir 111 with a capillary effect. Once liquid enters the reservoir 111, it accumulates relatively stably due to capillary forces and is unlikely to easily flow out due to movement of the electronic atomization device. This effectively prevents liquid damage to the microphone 40, thereby preventing microphone 40 from failing.

[0302] The specific formation method of the liquid storage tank 111 is not limited. It can be formed by protruding from the part of the bottom cover 11 located in the microphone mounting cavity 20c, or it can be formed by being recessed.

[0303] Exemplarily, referring to Figure 53, the liquid storage tank 111 includes a first liquid absorbent member 112, a second liquid absorbent member 113 and a third liquid absorbent member 114. The first liquid absorbent member 112 includes a first liquid absorbent groove 112a having a first opening 112b. The second liquid absorbent member 113 is arranged on the outer peripheral side of the first liquid absorbent member 112, and is spaced from the first liquid absorbent member 112 to form a second liquid absorbent groove 113a having a second opening 113b. The third liquid absorbent member 114 is arranged on the outer peripheral side of the second liquid absorbent member 113, and is spaced from the second liquid absorbent member 113 to form a third liquid absorbent groove 114a having a third opening 114b. The first liquid absorbent groove 112a, the second liquid absorbent groove 113a and the third liquid absorbent groove 114a are connected to each other.

[0304] The dimensions of the first, second, and third liquid aspiration grooves 112a, 113a, and 114a need to be sufficient to create a capillary effect, that is, to allow liquid entering the microphone mounting cavity 20c to sequentially fill the third, second, and first liquid aspiration grooves 114a, 113a, and 112a under capillary force. For example, the cross-sectional dimensions of the first, second, and third liquid aspiration grooves 112a, 113a, and 114a are no greater than 1 mm x 1 mm.

[0305] The shapes of the first absorbent member 112 , the second absorbent member 113 and the third absorbent member 114 are not limited, such as arc-shaped, square with an opening, etc.

[0306] In one embodiment, as shown in Figures 45 and 49 to 51 , the bracket assembly 20 includes a microphone mounting base 23. The microphone mounting base 23 comprises a base 233 mounted on the bottom cover 11, and a circuit board 234 located on the side of the base 233 facing away from the bottom cover 11. The base 233 and circuit board 234 together enclose a microphone mounting cavity 20c. The circuit board 234 has a through-hole 234a, through which at least a portion of the normal pressure sensing surface 40b communicates with the airflow path.

[0307] Specifically, the side of the circuit board 234 facing away from the microphone mounting cavity 20c is located in the airflow path. A microphone 40 is mounted on the circuit board 234. The side of the microphone 40 facing away from the circuit board 234 serves as a negative pressure sensing surface 40a, while the side of the microphone 40 facing closer to the circuit board 234 serves as a normal pressure sensing surface 40b. The circuit board 234 includes a via 234a corresponding to the normal pressure sensing surface 40b. In other words, the microphone 40 is inverted, and the normal pressure sensing surface 40b communicates with the airflow path through the via 234a, thereby connecting to the outside of the housing assembly 10. This ensures that normal pressure is maintained and prevents accidental activation due to airflow shock.

[0308] Furthermore, the connection between the circuit board 234 and the base 233 may also be sealed. For example, a first sealing rib may be provided between the end surface of the base 233 and the end surface of the circuit board 234. Referring to Figures 45 and 54, at the junction of the base 233 and the circuit board 234, a portion of one of the end surface of the base 233 and the end surface of the circuit board 234 protrudes to form a first sealing rib 235. In other words, the first sealing rib 235 may be formed on the end surface of the base 233 to seal with the end surface of the circuit board 234, thereby enhancing the sealing effect at the junction between the base 233 and the circuit board 234. Alternatively, the first sealing rib 235 may be formed on the end surface of the circuit board 234 to seal with the end surface of the base 233.

[0309] In one embodiment, the outer diameter of the microphone 40 may also be slightly larger than the inner diameter of the microphone mounting cavity 20 c so as to improve the sealing effect between the microphone 40 and the base 233 through interference fit with the base 233 .

[0310] Referring to Figure 43 , the airflow path includes a first flow opening 20a and a second flow opening 20b provided on the bracket assembly 20. Along the extension direction of the airflow path, the second flow opening 20b is located downstream of the first flow opening 20a, and the connection between the microphone mounting cavity 20c and the airflow path is located upstream of the second flow opening 20b.

[0311] As shown in Figures 42 and 43, the airflow path is the passage for airflow from the air inlet 10a to the air outlet 10b. The arrows in Figure 42 represent the direction of airflow. The first and second flow ports 20a, 20b are part of the airflow path, meaning that airflow along the airflow path also passes through the first and second flow ports 20a, 20b. The airflow path extends from the air inlet 10a toward the air outlet 10b. The second flow port 20b is located downstream of the first flow port 20a, meaning that airflow along the airflow path first passes through the first flow port 20a and then through the second flow port 20b.

[0312] The microphone mounting cavity 20c is connected to the area of ​​the air flow path located upstream of the second flow opening 20b. Therefore, the effect of forming a negative pressure in the microphone mounting cavity 20c can be adjusted by adjusting the cross-sectional area ratio of the first flow opening 20a and the second flow opening 20b.

[0313] The cross-sectional area of ​​the first flow opening 20a is the minimum cross-sectional area of ​​the airflow path, and the cross-sectional area of ​​the second flow opening 20b is not less than twice the cross-sectional area of ​​the first flow opening 20a and is the minimum cross-sectional area of ​​the airflow path downstream of the first flow opening 20a.

[0314] Specifically, the first flow opening 20a is the region with the smallest cross-sectional area in the airflow path, and the second flow opening 20b is the region of the airflow path downstream of the first flow opening 20a and with the smallest cross-sectional area. The cross-sectional area of ​​the second flow opening 20b can be equal to or greater than twice the cross-sectional area of ​​the first flow opening 20a.

[0315] It should be noted that because the connection between the microphone mounting cavity 20c and the airflow path, as well as the first flow opening 20a, are both located upstream of the second flow opening 20b, when the user inhales, a suction force is generated, causing the outside air to flow in through the air inlet 10a and out through the air outlet 10b. Therefore, the larger the cross-sectional area of ​​the second flow opening 20b and the smaller the cross-sectional area of ​​the first flow opening 20a, the greater the negative pressure generated within the microphone mounting cavity 20c due to the suction force.

[0316] Thus, by increasing the ratio of the cross-sectional area of ​​the second flow opening 20b to that of the first flow opening 20a, the second flow opening 20b can have a larger cross-sectional area relative to the first flow opening 20a, and the connection point between the microphone mounting cavity 20c and the airflow path is located upstream of the second flow opening 20b, thereby enhancing the effect of forming a negative pressure in the microphone mounting cavity 20c during inhalation, thereby facilitating the microphone 40 disposed in the microphone mounting cavity 20c to sense the pressure difference between the inside and outside of the microphone mounting cavity 20c, thereby ensuring that a sufficient negative pressure is formed in the microphone mounting cavity 20c to activate the microphone 40. This allows the user to activate the microphone 40 even when inhaling lightly (i.e., when the suction force is relatively low), thereby improving the activation sensitivity of the electronic atomization device.

[0317] The shapes and specific sizes of the first flow opening 20a and the second flow opening 20b are not limited. For example, the first flow opening 20a and the second flow opening 20b are both square holes, the size of the first flow opening 20a is 1.25mm×1.25mm, and the size of the second flow opening 20b is 1.8mm×1.8mm. For another example, the cross-sectional area of ​​the first flow opening 20a is 1.44mm 2 .

[0318] It should be noted that the cross-sectional area of ​​the first flow opening 20a is larger than the cross-sectional area of ​​the air inlet 10a, thereby reducing the inhalation resistance and facilitating inhalation for the user.

[0319] Furthermore, the relative positions of the connection point between the microphone mounting cavity 20c and the airflow path and the first flow opening 20a are not limited. The connection point between the microphone mounting cavity 20c and the airflow path can be located between the air inlet 10a and the first flow opening 20a, or between the first flow opening 20a and the second flow opening 20b.

[0320] In one embodiment, referring to FIG. 43 , the bracket assembly 20 includes a battery bracket 22 and a microphone mounting base 23 located between the battery bracket 22 and the housing assembly 10. The battery bracket 22 is a bracket for mounting the battery of the electronic atomization device. For example, the battery bracket 22 includes a first wall, a second wall, and a third wall. The first wall and the second wall are spaced apart, and the third wall is located between the first and second walls. A first flow opening 20a is provided in the first wall, and a second flow opening 20b is provided in the second wall. The first wall, the second wall, the third wall, and the housing assembly 10 together form a first channel 20f. The first wall is located on the side of the third wall near the air inlet 10a, and the second wall is located on the side of the third wall near the air outlet 10b. The first wall has a threading hole connecting the accommodating cavity and the airflow path, which facilitates the entry of the wire into the accommodating cavity. In addition, after the wire passes through the threading hole, it can be sealed by applying glue. Specifically, the first wall, the second wall, and the third wall can be integrally formed or spliced.

[0321] In one embodiment, referring to Figures 43, 46, 47, and 48, the airflow path includes a first channel 20f located upstream of the second flow outlet 20b. The bracket assembly 20 has a connecting port 20e connecting the microphone mounting cavity 20c and the first channel 20f. The first channel 20f has a bottom wall 21 on the side away from the air outlet 10b. A portion of the bottom wall 21 forms a liquid-conducting boss 211 that protrudes into the first channel 20f, such that the liquid-conducting boss 211 protrudes relative to other areas of the bottom wall 21. The connecting port 20e is disposed on the liquid-conducting boss 211. In this embodiment, both the first flow outlet 20a and the connecting port 20e are disposed on the liquid-conducting boss 211. The formation of the heat-conducting boss 211 prevents liquid flowing into the first channel 20f from flowing directly through the connecting port 20e into the microphone mounting cavity 20c, thereby preventing damage to the microphone 40.

[0322] In one embodiment, the first flow opening 20a is disposed on the liquid guiding boss 211 and upstream of the communication opening 20e, so that the airflow along the airflow path flows along the top surface of the liquid guiding boss 211 and flows through the communication opening 20e.

[0323] Because both the communication port 20e and the first flow port 20a are located on the liquid-guiding boss 211, with the first flow port 20a located upstream of the communication port 20e, the airflow from the first flow port 20a flows along the top surface of the liquid-guiding boss 211 and through the communication port 20e. Consequently, when liquid is present in the area of ​​the airflow path between the first flow port 20a and the air inlet 10a, as well as within the microphone mounting cavity 20c, some of the liquid flows upward into the first channel 20f under the action of suction, and is then blown off the liquid-guiding boss 211 by the airflow flowing along the top surface of the liquid-guiding boss 211.

[0324] It should be noted that the diameter of the communication port 20e should not be too small, as it would be difficult to machine. It should also not be too large, as it would easily allow liquid in the airflow path to enter the microphone mounting cavity 20c through the communication port 20e. For example, the diameter of the communication port 20e is no less than 0.6 mm and no greater than 1 mm, for example, 0.6 mm, 0.8 mm, or 1 mm.

[0325] Referring to FIG. 43 , in one embodiment, the electronic atomization device further includes a liquid-absorbing cotton 30 disposed within the first channel 20 f. Specifically, the liquid-absorbing cotton 30 absorbs liquid within the first channel 20 f to prevent liquid within the first channel 20 f (such as leaked atomized liquid, condensed liquid, etc.) from flowing into the microphone mounting cavity 20 c and damaging the microphone 40.

[0326] Furthermore, at least a portion of the absorbent cotton 30 is positioned at a lower height than the top surface of the liquid-guiding boss 211. Thus, when the electronic atomizer device is in the suction state with the air outlet 10b facing upward, the bottom end of the absorbent cotton 30 is positioned lower than the top ends of the first flow port 20a and the communication port 20e, thereby better absorbing the liquid in the first channel 20f and further reducing the possibility of the liquid in the first channel 20f entering the microphone mounting cavity 20c through the communication port 20e.

[0327] In one embodiment, as shown in Figures 43, 44, 45, and 54, the microphone mounting cavity 20c is disposed on the microphone mounting base 23. The microphone mounting base 23 also has a second channel 23a. One end of the second channel 23a communicates with the microphone mounting cavity 20c, located on the side of the negative pressure sensing surface 40a facing away from the air outlet 10b. The other end of the second channel 23a communicates with the first channel 20f.

[0328] The end of the second channel 23a that communicates with the microphone mounting cavity 20c is located on the side of the negative pressure sensing surface 40a that faces away from the air outlet. Therefore, after liquid enters the microphone mounting cavity 20c through the second channel 23a, it will not come into contact with the negative pressure sensing surface 40a and damage the microphone 40.

[0329] Furthermore, to further enhance the negative pressure generated within the microphone mounting chamber 20c during suction, it is necessary to ensure the sealing performance of the microphone mounting chamber 20c. This prevents the microphone mounting chamber 20c from being directly connected to the outside world in addition to being connected to the airflow path via the second channel 23a, thereby preventing the formation of a strong negative pressure within the microphone mounting chamber 20c. Referring to Figures 45, 54, and 55, the battery holder 22 has a communication port 20e that connects the first channel 20f and the second channel 23a. At the point where the communication port 20e connects to the second channel 23a, a second sealing rib 231 is provided between the end surface of the microphone mounting base 23 and the end surface of the battery holder 22.

[0330] Specifically, the end surface of the microphone mounting base 23 may be formed with a second sealing rib 231 to seal against the end surface of the battery holder 22, thereby improving the sealing effect at the connection point between the communication port 20e and the second channel 23a. Of course, the end surface of the battery holder 22 may also be formed with a second sealing rib 231 to seal against the end surface of the microphone mounting base 23.

[0331] In one embodiment, a third sealing rib 232 is provided between the end surface of the microphone mounting base 23 and the end surface of the housing assembly 10 at the junction of the microphone mounting base 23 and the housing assembly 10. Specifically, the third sealing rib 232 can be formed on the end surface of the microphone mounting base 23 to seal with the end surface of the housing assembly 10, thereby improving the sealing effect at the junction of the microphone mounting base 23 and the housing assembly 10. Of course, the third sealing rib 232 can also be formed on the end surface of the housing assembly 10 to seal with the end surface of the microphone mounting base 23.

[0332] In one embodiment, the outer diameter of the outer wall surface of the battery holder 22 on the side close to the microphone mounting seat 23 is slightly larger than the inner diameter of the shell assembly 10, so as to improve the sealing effect between the battery holder 22 and the shell assembly 10 through interference fit with the shell assembly 10.

[0333] Another embodiment of the present application provides an electronic atomization device, comprising an atomization assembly 50 and a power supply assembly as described in any of the above embodiments. The atomization assembly 50 is disposed within the housing assembly 10 and is electrically connected to the microphone 40.

[0334] The atomizer assembly 50 is used to liquefy the atomized liquid to generate an aerosol, which then flows out of the air outlet 10b along the airflow path. When a user inhales through the air outlet 10b, a pressure differential is created between the negative pressure sensing surface 40a and the normal pressure sensing surface 40b of the microphone 40, activating the microphone 40 and causing the atomizer assembly 50 to operate and generate aerosol. When the user stops inhaling, the pressure in the microphone mounting cavity 20c returns to normal, the microphone 40 deactivates, and the atomizer assembly 50 ceases operation.

[0335] Referring to Figures 56-58, 63-65, and 69-71, an embodiment of the present application provides an electronic atomization device 100 / 200 / 300 for heating an atomization medium to generate an aerosol for use by a user. The atomization medium includes but is not limited to liquid medicines and oils of materials used for medical, health, wellness, and beauty purposes.

[0336] The electronic atomization device 100 / 200 / 300 includes an atomization assembly 110 / 210 / 310, a battery assembly 120 / 220 / 320, and a refill assembly 130 / 230 / 330. The atomization assembly 110 / 210 / 310 stores atomizing medium. The battery assembly 120 / 220 / 320 is electrically connected to the atomization assembly 110 / 210 / 310 to power the atomization assembly 110 / 210 / 310. The atomization assembly 110 / 210 / 310 heats the atomized aerosol using the electrical energy to generate the aerosol.

[0337] The refill assembly 130 / 230 / 330 is provided with an air outlet channel 130b / 230b / 330b that allows airflow, and a refill chamber 130a / 230a / 330a for storing atomized medium. During transportation and storage, the refill assembly 130 / 230 / 330 and the atomizer assembly 110 / 210 / 310 can be placed separately. When the electronic atomizer device 100 / 200 / 300 is in use, the refill assembly 130 / 230 / 330 can be installed on the atomizer assembly 110 / 210 / 310. The aerosol generated by the atomizer assembly 110 / 210 / 310 can flow out through the air outlet channel 130b / 230b / 330b, while the refill chamber 130a / 230a / 330a is used to replenish the atomizer assembly 110 / 210 / 310 with atomized medium.

[0338] In some other embodiments, an air outlet channel may be directly provided in the atomizer assembly 110 / 210 / 310. Thus, even when the refill assembly 130 / 230 / 330 is not installed, inhalation may be performed directly through the atomizer assembly 110 / 210 / 310. In other embodiments, a nozzle 140 / 240 / 340 may be installed in the atomizer assembly 110 / 210 / 310, and the aerosol generated by the atomizer assembly 110 / 210 / 310 may be discharged through the nozzle 140 / 240 / 340.

[0339] The atomizer assembly 110 / 210 / 310 includes an atomizer bracket 112 / 212 / 312, an atomizer core 114 / 214 / 314, and a sealing member 115 / 215 / 315. The atomizer core 114 / 214 / 314 is located within the atomizer bracket 112 / 212 / 312. The atomizer core 114 / 214 / 314 and the atomizer bracket 112 / 212 / 312 together define a liquid storage chamber 110a / 210a / 310a for storing atomized medium. The atomizer bracket 112 / 212 / 312 defines a liquid inlet channel 113a / 213a / 313a that communicates with the liquid storage chamber 110a / 210a / 310a. The blocking member 115 / 215 / 315 can be switched between a first position, which blocks the liquid inlet of the liquid inlet channel 113a / 213a / 313a, and a second position, which opens the liquid inlet. When the further metering assembly 130 / 230 / 330 is mounted on the atomizer bracket 112 / 212 / 312, the blocking member 115 / 215 / 315 can be switched to the second position, which opens the liquid inlet of the liquid inlet channel 113a / 213a / 313a.

[0340] It can be understood that in some embodiments, after the continuing component 130 / 230 / 330 is detachably installed in the atomizer component 110 / 210 / 310, when the continuing component 130 / 230 / 330 is consumed, the current continuing component 130 / 230 / 330 can be removed to be replaced with a new continuing component 130 / 230 / 330. In other embodiments, when the continuing component 130 / 230 / 330 is inseparable from the atomizer component 110 / 210 / 310, the continuing component 130 / 230 / 330 cannot be removed from the atomizer component 110 / 210 / 310 after it is installed in the atomizer component 110 / 210 / 310.

[0341] Before the further metering assembly 130 / 230 / 330 is installed on the atomizing assembly 110 / 210 / 310, the blocking member 115 / 215 / 315 blocks the liquid inlet of the liquid inlet channel 113a / 213a / 313a, so that the atomized medium in the liquid storage chamber 110a / 210a / 310a will not leak through the liquid inlet channel 113a / 213a / 313a.

[0342] When the further metering assembly 130 / 230 / 330 is installed on the atomizing assembly 110 / 210 / 310, the blocking member 115 / 215 / 315 moves to a position to open the liquid inlet of the liquid inlet channel 113a / 213a / 313a, and the further metering chamber 130a / 230a / 330a is connected to the liquid storage chamber 110a / 210a / 310a through the liquid inlet channel 113a / 213a / 313a, and the atomized medium in the further metering chamber 130a / 230a / 330a can flow into the liquid storage chamber 110a / 210a / 310a through the liquid inlet channel 113a / 213a / 313a.

[0343] In this way, the atomizer assembly 110 / 210 / 310 can be placed separately from the refill assembly 130 / 230 / 330 during transportation and storage. The liquid inlet channel 113a / 213a / 313a of the atomizer assembly 110 / 210 / 310 is sealed by the sealing member 115 / 215 / 315, thereby preventing leakage and deterioration of the atomized medium. When the electronic atomizer device 100 / 200 / 300 is needed, the liquid inlet of the atomizer assembly 110 / 210 / 310 is opened synchronously with the installation of the refill assembly 130 / 230 / 330, and is quickly connected to the refill assembly 130 / 230 / 330, thereby avoiding the risk of leakage in the liquid storage chamber 110a / 210a / 310a.

[0344] Furthermore, the liquid inlet of the liquid inlet channel 113a / 313a is opened on the top surface or side surface of the liquid inlet channel 113a / 313a, and the blocking member 115 / 315 is located in the liquid inlet channel 113a / 313a to block the liquid inlet when in the first position. In other embodiments, the liquid inlet of the liquid inlet channel 213a is opened on the side surface of the liquid inlet channel 213a, and the blocking member 215 is disposed outside the liquid inlet channel 213a to block the liquid inlet.

[0345] In some embodiments, the continue metering assembly 130 / 230 includes a resisting portion that protrudes from the end surface of the continue metering assembly 130 / 230 that contacts the atomizer assembly 110 / 210. In other embodiments, the atomizer assembly 310 includes a resisting portion that protrudes from the end surface of the atomizer assembly 310 that contacts the continue metering assembly 330. When the continue metering assembly 130 / 230 / 330 is installed on the atomizer assembly 110 / 210 / 310, the blocking member 115 / 215 / 315 moves under the push of the resisting portion to open the liquid inlet channel 113a / 213a / 313a.

[0346] It can be understood that the setting position and formation method of the supporting portion can be set as needed, as long as it can synchronously push the blocking member 115 / 215 / 315 to move to open the liquid inlet of the liquid inlet channel 113a / 213a / 313a when the refill assembly 130 / 230 / 330 is installed on the atomization assembly 110 / 210 / 310.

[0347] Referring to Figures 58, 65, and 71, the atomizer bracket 112 / 212 / 312 includes a bracket body 111 / 211 / 311. The bracket body 111 / 211 / 311 has a hollow, rotating body structure, with the central axis of the bracket body 111 / 211 / 311 being defined as a first direction (i.e., the vertical direction in Figure 58). The bracket body 111 / 211 / 311 includes an annular sleeve 1112 / 2112 / 3112 and a partition plate 1114 / 2114 / 3114 disposed at one axial end of the annular sleeve 1112 / 2112 / 3112. The annular sleeve 1112 / 2112 / 3112 and the partition plate 1114 / 2114 / 3114 together form a storage space for accommodating the atomizer core 114 / 214 / 314. Specifically, in some embodiments, the partition plate 1114 / 2114 is located outside the annular sleeve 1112 / 2112, and the outer diameter of the partition plate 1114 / 2114 is larger than the outer diameter of the annular sleeve 1112 / 2112. In other embodiments, the partition plate 3114 is located inside the annular sleeve 3112. The atomizer core 114 / 214 / 314 is accommodated in the accommodating space formed by the bracket body 111 / 211 / 311. A liquid storage chamber 110a / 210a / 310a for storing atomized medium is formed between the atomizer core 114 / 214 / 314 and the partition plate 1114 / 2114 / 3114.

[0348] Furthermore, the bracket body 111 / 211 / 311 also includes a central tube 1116 / 2116 / 3116, one end of the central tube 1116 / 2116 / 3116 is connected to the partition plate 1114 / 2114 / 3114, and the other end of the central tube 1116 / 2116 / 3116 extends along the first direction until it is inserted into the atomizer core 114 / 214 / 314, and a central airway 1116a / 2116a / 3116a is formed in the central tube 1116 / 2116 / 3116 to connect the atomizer core 114 / 214 / 314 and the follow-up assembly 130 / 230 / 330.

[0349] The atomizer core 114 / 214 / 314 includes an atomizer base 1141 / 2141 / 3141, a top cover 1142 / 2142 / 3142, a heating element 1143 / 2143 / 3143, a positive conductive electrode 1144 / 2144 / 3144, and a negative conductive electrode 1145 / 2145 / 3145. The atomizer base 1141 / 2141 / 3141 is coupled to an end of the bracket body 111 / 211 / 311 away from the partition plate 1114 / 2114 / 3114, and the top cover 1142 / 2142 / 3142 is coupled to an end of the atomizer base 1141 / 2141 / 3141 facing the partition plate 1114 / 2114 / 3114. The atomizer base 1141 / 2141 / 3141 and the top cover 1142 / 2142 / 3142 jointly define an atomizer chamber 114a / 214a / 314a, and the liquid storage chamber 110a / 210a / 310a is formed between the top cover 1142 / 2142 / 3142 and the partition plate 1114 / 2114 / 3114 of the bracket body 111 / 211 / 311.

[0350] Furthermore, the top cover 1142 / 2142 / 3142 includes a top cover top wall and a top cover side wall extending from the edge of the top cover top wall in a direction away from the partition plate 1114 / 2114 / 3114, and the top cover top wall is provided with a top cover center hole and at least one lower liquid hole. The top cover center hole is located at the center position of the top cover 1142 / 2142 / 3142 and is connected to the atomization chamber. One end of the central tube 1116 / 2116 / 3116 of the atomization bracket 112 / 212 / 312 can be inserted into the top cover center hole, so that the central airway 1116a / 2116a / 3116a of the atomization bracket 112 / 212 / 312 is connected to the atomization chamber. The lower liquid hole is located on the periphery of the center hole of the top cover and is used to connect the atomizing chamber 114a / 214a / 314a with the liquid storage chamber 110a / 210a / 310a. The atomizing medium in the liquid storage chamber 110a / 210a / 310a can flow into the atomizing chamber 114a / 214a / 314a through the lower liquid hole.

[0351] The heating element 1143 / 2143 / 3143 is housed in the atomizing chamber 114a / 214a / 314a and includes a substrate and a heating element. In some embodiments, the substrate can be formed of a high-temperature resistant porous material such as ceramic, and the heating element is formed on the surface of the substrate, and the heating element can generate heat under the action of electrical energy. One end of the positive conductive electrode 1144 / 2144 / 3144 and the negative conductive electrode 1145 / 2145 / 3145 are electrically connected to the heating element 1143 / 2143 / 3143, and the other end of the positive conductive electrode 1144 / 2144 / 3144 and the negative conductive electrode 1145 / 2145 / 3145 are electrically connected to the battery assembly 120 / 220 / 320.

[0352] In some other embodiments, the heating element includes a heating body and liquid storage cotton wrapped around the heating body. The atomized medium in the liquid storage cavity 110a / 210a / 310a can be absorbed by the liquid storage cotton and directed to the surface of the heating body.

[0353] In this way, the atomized medium in the liquid storage chamber 110a / 210a / 310a flows into the atomizing chamber 114a / 214a / 314a through the lower liquid hole, the heating element 1143 / 2143 / 3143 in the atomizing chamber 114a / 214a / 314a absorbs the atomized medium and generates heat under the action of the electric energy of the battery assembly 120 / 220 / 320 to heat the atomizing medium. The atomized medium is atomized by the heat to produce aerosol, and the aerosol in the atomizing chamber 114a / 214a / 314a flows out through the central airway 1116a / 2116a / 3116a and the air outlet channel 130b / 230b / 330b in sequence. To ensure that the air pressure within the liquid storage chamber 110a / 210a / 310a is balanced with the external atmosphere, the top cover 1142 / 2142 / 3142 is further formed with a ventilation channel connected to the liquid storage chamber 110a / 210a / 310a. The ventilation channel can be formed in the side wall of the top cover or in the top wall of the top cover. In other embodiments, the ventilation channel can also be formed between the heating top cover 1142 / 2142 / 3142 and the heating element 1143 / 2143 / 3143.

[0354] Please refer to Figures 58, 59 and 60. The first embodiment of the present application provides an electronic atomization device 100.

[0355] The atomizer bracket 112 also includes two conductive members 113. These two conductive members 113 are protruding from a side of the partition plate 1114 away from the liquid storage chamber 110a. The two conductive members 113 are spaced apart along a radial direction of the partition plate 1114. Each conductive member 113 includes a first conductive portion 1132 and a second conductive portion 1134 that are interconnected. The first conductive portion 1132 is connected to the partition plate 1114 and has a hollow cylindrical structure. The liquid inlet channel 113a is formed within the first conductive portion 1132. The open end of the first conductive portion 1132 away from the partition plate 1114 forms the liquid inlet of the liquid inlet channel 113a, thereby forming the liquid inlet at the top surface of the liquid inlet channel 113a. The second conductive portion 1134 is connected to one end of the first conductive portion 1132 away from the partition plate 1114. The second conductive portion 1134 extends from the inner side wall of the first conductive portion 1132 in a direction away from the partition plate 1114, and the cross-section of the second conductive portion 1134 perpendicular to the first direction is semicircular. The second conductive portion 1134 is used to extend into the continue metering component 130 to open the continue metering cavity 130a.

[0356] There are two sealing members 115, each cylindrical structure with a shape and size that matches the liquid inlet channel 113a. Before the metering assembly 130 is installed on the atomizer bracket 112, each sealing member 115 is at least partially embedded in a corresponding liquid inlet channel 113a. The sealing members 115 and the liquid inlet channels 113a have an interference fit to seal the liquid inlet of the liquid inlet channel 113a.

[0357] Before the further metering assembly 130 is installed on the atomizer bracket 112, the blocking member 115 is at least partially embedded in the liquid inlet channel 113a formed by the first conductive portion 1132. The blocking member 115 and the liquid inlet channel 113a form an interference fit to seal the liquid inlet of the liquid inlet channel 113a, thereby preventing the leakage of the atomized medium in the liquid storage chamber 110a. When the further metering assembly 130 is installed on the atomizer bracket 112, the blocking member 115 is pushed away from the liquid inlet channel 113a by the further metering assembly 130, thereby opening the liquid inlet of the liquid inlet channel 113a. At the same time, the second conductive portion 1134 extends into the further metering assembly 130 to open the further metering chamber 130a. As a result, the atomized medium in the further metering chamber 130a can flow into the liquid storage chamber 110a through the liquid inlet channel 113a.

[0358] It can be understood that the number of the conducting member 113 and the blocking member 115 is not limited thereto. In some other embodiments, the number of the conducting member 113 and the blocking member 115 can be one or more.

[0359] Furthermore, the blocking member 115 is flexibly connected to the atomizing bracket 112 , so the blocking member 115 can move under the push of the continuing assembly 130 to open the liquid inlet channel 113 a .

[0360] Specifically, in conjunction with Figures 58, 59 and 61, the atomizer assembly 110 also includes a blocking connector 116, which is integrally formed with two blocking members 115. Specifically, the blocking connector 116 is an annular structure, and the blocking connector 116 is connected to the atomizer bracket 112 through a central tube 1116 that is sleeved on the atomizer bracket 112. The two blocking members 115 are respectively located on opposite sides of the blocking connector 116 in a radial direction, and each blocking member 115 is rotatably connected to the blocking connector 116. In this way, the blocking member 115 is flexibly connected to the atomizer bracket 112 through the blocking connector 16. When the further metering assembly 130 is installed on the atomizer bracket 112, the blocking member 115 rotates with its connection with the blocking connector 116 as the rotation center under the push of the further metering assembly 130 and disengages from the liquid inlet channel 113a.

[0361] Since the blocking member 115 is always connected to the blocking connector 116, and the blocking connector 116 is always mounted on the central tube 1116 of the atomizer bracket 112, the blocking member 115 that is separated from the liquid inlet channel 113a can be prevented from floating in the liquid storage chamber 110a. At the same time, the number of parts of the electronic atomizer device 100 is reduced, and the overall structure of the electronic atomizer device 100 is simplified.

[0362] Referring again to Figures 58, 59, and 60, the atomizer assembly 110 further includes two channel seals 117. The two channel seals 117 are respectively disposed outside the first conductive portions 1132 of the two conductive members 113. When the further metering assembly 130 is mounted on the atomizer bracket 112, the second conductive portion 1134 is inserted into the further metering assembly 130 and forms an interference fit therewith, thereby preventing the atomized medium from leaking through the gap between the sealing cover 133 and the atomizer bracket 112. In a preferred embodiment, the two channel seals 117 are integrally formed and interconnected, thereby reducing the number of parts in the electronic atomizer device 100 and simplifying its overall structure. In other embodiments, the channel seals 117 may also be disposed within the further metering assembly 130. When the further metering assembly 130 is mounted on the atomizer bracket 112, the second conductive portion 1134 may be inserted into the channel seals 117 and form an interference fit therewith.

[0363] As shown in Figures 58 and 59, the metering assembly 130 includes a metering housing and a sealing member 134. The metering housing includes an outer ring housing 131, an inner ring housing 132, and a sealing cover 133. The outer ring housing 131 is a hollow cylindrical structure with one end open, and the central axis of the outer ring housing 131 extends along a first direction. The inner ring housing 132 extends from the closed end of the outer ring housing 131 along the first direction to the open end of the outer ring housing 131. An outlet passage 130b extending along the first direction is formed within the inner ring housing 132. One end of the outlet passage 130b passes through the closed end of the outer ring housing 131 to communicate with the external atmosphere, and the other end of the outlet passage 130b communicates with the central airway 1116a of the atomizer bracket 112. In other embodiments, the central airway 1116a may not be provided in the metering assembly 130, and the central airway 1116a may be used only to store the atomizing medium, and the aerosol generated by the atomizer assembly 110 may flow out through the atomizer assembly 110 itself.

[0364] The sealing cover 133 is a body of revolution. It is mounted on the open end of the outer ring housing 131 and sleeved onto the inner ring housing 132. The outer ring housing 131, inner ring housing 132, and sealing cover 133 collectively form a further flow chamber 130a that circumferentially surrounds the inner ring housing 132. The sealing cover 133 is formed with two communication holes 1331 extending through the further flow chamber 130a. These two communication holes 1331 are spaced apart along a radial direction of the sealing cover 133, with the central axis of each communication hole 1331 extending along a first direction. Each communication hole 1331 includes a first communication end 1331a and a second communication end 1331b that communicate with each other. The first communication end 1331a is located on the side of the second communication end 1331b closer to the sealed end of the outer ring housing 131, and the inner diameter of the second communication end 1331b is either larger or smaller than the inner diameter of the first communication end 1331a.

[0365] When the continue metering assembly 130 is mounted on the atomizer bracket 112, the first conducting portion 1132 of the conducting member 113 can extend through the first connecting end 1331a into the continue metering cavity 130a. The second conducting portion 1134 of the conducting member 113 is located within the second connecting end 1331b. The conducting seal 134, which is sleeved around the second conducting portion 1134, is located within the second connecting end 1331b. The conducting seal 134 has an interference fit with the second conducting portion 1134 and the second connecting end 1331b, respectively, thereby sealing the gap between the conducting member 113 and the wall of the communicating hole 1331. In another embodiment, a channel seal 117 is disposed within the second connecting end 1331b. When the continue metering assembly 130 is mounted on the atomizer bracket 112, the second conducting portion 1134 can be inserted into the channel seal 117.

[0366] Furthermore, the sealing cover 133 is provided with a protruding abutment 1333 for pushing the sealing member 115. When the further metering assembly 130 is mounted on the atomizer bracket 112, the sealing member 115 moves under the push of the abutment 1333 to open the liquid inlet channel 113a. Specifically, one end of the abutment 1333 is connected to the inner wall of the first connecting end 1331a of the communicating hole 1331, and the other end of the abutment 1333 extends through the second connecting end 1331b along the first direction to extend out of the communicating hole 1331. The cross-section of the abutment 1333 perpendicular to the first direction is a semicircular arc.

[0367] As shown in Figures 58, 59 and 62, there are two seals 134 installed on the sealing cover 133. Each seal 134 is a cylindrical structure with a shape and size matching the first connecting end 1331a of the connecting hole 1331.

[0368] Before the atomizer assembly 110 is mounted on the further metering assembly 130, each sealing member 134 is at least partially embedded within the first connecting end 1331a of a corresponding communication hole 1331, and the sealing member 134 forms an interference fit with the communication hole 1331 to seal the communication hole 1331. When the further metering assembly 130 is mounted on the atomizer bracket 112, the conductive member 113 extends through the communication hole 1331 into the further metering chamber 130a. The sealing member 134 located in the liquid inlet channel 113a is pushed away from the communication hole 1331 by the second conductive portion 1134 of the conductive member 113. Therefore, the atomized medium in the further metering chamber 130a can enter the liquid inlet channel 113a through the communication hole 1331.

[0369] Furthermore, the atomizer assembly 110 also includes a sealing connector 135, which is integrally formed with the two sealing members 134. Specifically, the sealing connector 135 includes an inner connecting ring 1352, an outer connecting ring 1354, and a connecting arm 1356 connected between the inner connecting ring 1352 and the outer connecting ring 1354. The inner connecting ring 1352 is a hollow annular structure to be sleeved on the inner ring shell 132, and the outer connecting ring 1354 is a hollow annular structure to surround the edge of the sealing cover 133. The two sealing members 134 are respectively connected to opposite sides of the outer connecting ring 1354 in a radial direction. In this way, the sealing member 134 is flexibly mounted on the sealing cover 133 through the sealing connector 135. When the continuous metering assembly 130 is mounted on the atomizer assembly 110, the sealing member 134 rotates with its connection with the sealing connector 135 as the rotation center under the push of the conductive member 113 and disengages from the communicating hole 1331.

[0370] Since the seal 134 is always connected to the sealing connector 135, it can prevent the seal 134 from floating in the metering chamber 130a after being separated from the connecting hole 1331. At the same time, the number of parts of the electronic atomization device 100 is reduced and the overall structure of the electronic atomization device 100 is simplified.

[0371] The connection principle of the atomizing assembly 110 and the continuing assembly 130 of the first embodiment is as follows:

[0372] Before installing the further metering assembly 130 in the atomizer assembly 110: In the atomizer assembly 110, the blocking member 115 is embedded in the first conducting portion 1132 of the conducting member 113. The blocking member 115 and the first conducting portion 1132 form an interference fit to block the liquid inlet of the liquid inlet channel 113a. In the further metering assembly 130, the sealing member 134 is embedded in the first connecting end 1331a of the connecting hole 1331 of the sealing cover 133. The sealing member 134 and the first connecting end 1331a form an interference fit to block the connecting hole 1331.

[0373] When the further metering assembly 130 is installed on the atomizer assembly 110, the conducting member 113 of the atomizer assembly 110 extends through the communicating hole 1331 of the sealing cover 133 into the further metering chamber 130a. The sealing member 134, pushed by the conducting member 113, rotates to disengage from the communicating hole 1331. Simultaneously, the abutting portion 1333 of the sealing cover 133 passes through the liquid inlet channel 113a and extends into the liquid storage chamber 110a. The blocking member 115, pushed by the abutting portion 1333, rotates to disengage from the liquid inlet channel 113a. The channel sealing member 117 is located in the second communicating end 1331b of the communicating hole 1331 and has an interference fit with the second communicating end 1331b. Therefore, the metering chamber 130a and the liquid storage chamber 110a are connected to each other through the liquid inlet channel 113a, and the atomized medium in the metering chamber 130a can enter the liquid storage chamber 110a through the liquid inlet channel 113a. At the same time, the metering chamber 130a and the liquid storage chamber 110a can also exchange gas to balance the air pressure.

[0374] During the above installation process, since the further measuring chamber 130a and the liquid storage chamber 110a are connected at the same time, the risk of liquid leakage caused by the liquid storage chamber 110a being connected to the atmosphere first can be avoided.

[0375] As shown in FIG. 65 and FIG. 66 , the second embodiment of the present application provides an electronic atomization device 200 .

[0376] Referring to Figures 65, 66, and 67, the atomizer bracket 212 further includes two conductive members 213. These two conductive members 213 are protruding from the side of the partition plate 2114 away from the liquid storage chamber 210a. The two conductive members 213 are spaced apart along a radial direction of the partition plate 2114. Each conductive member 213 has a hollow cylindrical structure. A liquid inlet channel 213a is formed within the conductive member 213, and the liquid inlet of the liquid inlet channel 213a is located on the side of the end of the liquid inlet channel 213a away from the liquid storage chamber 210a. There are also two blocking members 215, each of which has a hollow cylindrical structure and is sleeved onto the conductive member 213.

[0377] Before the atomizer bracket 212 is mounted on the metering assembly 230, the blocking member 215 is mounted on the end of the conducting member 213 away from the partition plate 2114 and blocks the liquid inlet of the liquid inlet channel 213a, thereby preventing the atomized medium in the liquid storage chamber 210a from flowing out through the liquid inlet channel 213a. When the metering assembly 230 is mounted on the atomizer bracket 212, the end of the conducting member 213 provided with the liquid inlet of the liquid inlet channel 213a extends into the metering chamber 230a. Under the force of the metering assembly 230, the blocking member 215 slides in the first direction to the end of the conducting member 213 closer to the liquid storage chamber 210a, thereby opening the liquid inlet of the liquid inlet channel 213a. Therefore, the atomized medium in the metering chamber 230a can flow into the liquid storage chamber 210a through the liquid inlet channel 213a.

[0378] Furthermore, when the blocking member 215 slides to one end of the conducting member 213 close to the liquid storage chamber 210a under the push of the continue metering component 230, the blocking member 215 is interference fit with the conducting member 213 and the continue metering component 230 respectively to close the gap between the conducting member 213 and the continue metering component 230.

[0379] Please continue to refer to Figures 65 and 66. The structure of the metering component 230 of the electronic atomization device 200 of the second embodiment is roughly the same as that of the metering component 130 in the first embodiment, including a metering shell, a seal 234 and a sealing connector 135. The metering shell includes an outer ring shell 231, an inner ring shell 232 and a sealing cover 233. An air outlet channel 230b is formed in the inner ring shell 232, and the outer ring shell 231, the inner ring shell 232 and the sealing cover 233 together form a metering chamber 230a. The sealing cover 233 is provided with a connecting hole 2331 connecting to the metering chamber 230a. Each connecting hole 2331 includes a first connecting end 2331a and a second connecting end 2331b that are connected to each other. The sealing connector 135 and the sealing component 134 are integrally formed, and the sealing component 134 is flexibly mounted on the sealing cover 133 through the sealing connector 135.

[0380] The difference between the continue metering component 230 of the second embodiment and the continue metering component 130 of the first embodiment is that the inner diameter of the second connecting end 2331b of the sealing cover 233 of the continue metering component 230 is larger or smaller than the inner diameter of the first connecting end 2331a, and a step surface is formed between the first connecting end 2331a and the second connecting end 2331b to serve as a supporting portion for supporting the sealing member 215.

[0381] In this way, when the further metering component 230 is installed on the atomizer bracket 212, the conducting member 213 can pass through the first connecting end 2331a and extend into the further metering chamber 230a. Under the support of the step surface (i.e., the supporting portion) formed between the first connecting end 2331a and the second connecting end 2331b, the blocking member 215 remains in the second connecting end 2331b and is interference fit with the second connecting end 2331b, thereby playing a sealing role while conducting the liquid inlet channel 213a, preventing the atomized medium from flowing out of the gap between the atomizer bracket 212 and the further metering component 230.

[0382] The connection principle of the atomizing assembly 210 and the continuing assembly 230 of the second embodiment is as follows:

[0383] Before installing the refill assembly 230 on the atomizer assembly 210: In the atomizer assembly 210, the blocking member 215 is sleeved over the conducting member 213 to seal the liquid inlet of the liquid inlet channel 213a. In the refill assembly 230, the sealing member 234 is embedded in the first connecting end 2331a of the connecting hole 2331 of the sealing cover 233. The sealing member 234 and the first connecting end 2331a have an interference fit to seal the connecting hole 2331.

[0384] When the metering assembly 230 is installed in the atomizer assembly 210, the conducting member 213 of the atomizer assembly 210 extends through the connecting hole 2331 of the sealing cover 233 into the metering chamber 230a. The sealing member 234 rotates under the push of the conducting member 213 to disengage from the connecting hole 2331. The blocking member 215, supported by the stepped surface within the connecting hole 2331 of the sealing cover 233, remains within the second connecting end 2331b and forms an interference fit with the second connecting end 2331b. Therefore, the metering chamber 230a and the liquid storage chamber 210a are connected to each other through the liquid inlet channel 213a. The atomized medium in the metering chamber 230a can enter the liquid storage chamber 210a through the liquid inlet channel 213a. At the same time, gas exchange can occur between the metering chamber 230a and the liquid storage chamber 210a to balance the air pressure.

[0385] During the above installation process, since the further measuring chamber 230a and the liquid storage chamber 210a are connected at the same time, the risk of liquid leakage caused by the liquid storage chamber 210a being connected to the atmosphere first can be avoided.

[0386] Please refer to Figures 71, 72 and 73. The third embodiment of the present application provides an atomization assembly 310.

[0387] There are two conductive members 313, which are protruding from the side of the partition plate 3114 away from the liquid storage chamber 310a. The two conductive members 313 are spaced apart in a radial direction of the partition plate 3114, and each conductive member 313 includes at least one conductive portion 3132. Specifically, in one embodiment, each conductive member 313 includes two conductive portions 3132, which are spaced apart in the radial direction of the atomizer bracket 312 (as shown in Figure 77). A liquid inlet channel 313a is formed between the two conductive portions 3132, and the height of one conductive portion 3132 protruding from the bracket body 311 is greater than the height of the other conductive portion 3132 protruding from the bracket body 311. The width of the conductive portion 3132 with a higher height, which is farther from the bracket body 311, gradually decreases from the end closer to the bracket body 311 to the end farther from the bracket body 311 to form a tapered structure. It can be understood that the number of the conductive members 313 is not limited thereto. In other embodiments, there may be only one conductive member 313 or more conductive members 313 .

[0388] When the further metering component 330 is installed on the atomizing bracket 312, the two conducting parts 3132 successively contact the further metering component 330 and puncture the further metering component 330, thereby connecting the further metering chamber 230a with the liquid inlet channel 313a. Therefore, the atomized medium in the further metering chamber 230a can flow into the liquid storage chamber 310a through the liquid inlet channel 313a.

[0389] Please refer to Figures 72, 73, 78 and 79. The atomizer assembly 310 also includes a supporting portion 316. The supporting portion 316 is roughly T-shaped, including a connecting end 3161 and a supporting end 3163. The connecting end 3161 is a rod-shaped structure extending along the first direction. The supporting end 3163 and the blocking member 315 are respectively arranged at opposite ends of the connecting end 3161, and the cross-sectional areas of the supporting end 3163 and the blocking member 315 are both larger than the cross-sectional area of ​​the connecting end 3161. The supporting end 3163 extends out of the liquid inlet channel 313a through the gap between the two conducting portions 3132.

[0390] When the further metering assembly 330 is mounted on the atomizing bracket 312 , since the two conducting portions 3132 are spaced apart from each other, the abutting end 3163 is located between the two conducting portions 3132 and abuts against the bracket body 311 .

[0391] Thus, before the metering assembly 330 is installed on the atomizing bracket 312, the blocking member 315 is positioned within the liquid inlet channel 313a to block the liquid inlet. When the metering assembly 330 is installed on the atomizing bracket 312, the conducting member 313 pierces the metering assembly 330, and the abutting portion 316, supported by the metering assembly 330, moves until the abutting end 3163 abuts the partition plate 3114 of the bracket body 311. Driven by the abutting portion 316, the blocking member 315 disengages the liquid inlet channel 313a and enters the liquid storage chamber 310a. A gap exists between the connecting end 3161 of the abutting portion 316 and the liquid inlet channel 313a. Therefore, the atomized medium in the metering chamber 230a flows into the liquid storage chamber 310a from between the connecting end 3161 and the wall of the liquid inlet channel 313a. Furthermore, the connecting end 3161 serves to drain the atomized medium. Furthermore, the blocking member 315 is limited relative to the bracket body 311 by the abutting end 3163 of the abutting portion 316 , thereby preventing the blocking member 315 from falling off the bracket body 311 and floating in the liquid storage cavity 310 a .

[0392] Furthermore, the atomizer assembly 310 also includes a puncture portion 317, which is arranged on the side of the supporting end 3163 of the supporting portion 316 away from the connecting end 3161. The cross-sectional area of ​​the puncture portion 317 gradually decreases from close to the supporting end 3163 to away from the supporting end 3163. When the refill assembly 330 is installed on the atomizer bracket 312, the puncture portion 317 can puncture the sealing cover 333 together with the conductive member 313.

[0393] Furthermore, in some embodiments, the blocking member 315, the supporting portion 316 and the puncturing portion 317 are integrally formed (as shown in FIG. 78 ); in other embodiments, as shown in FIG. 79 , the blocking member 315 includes a blocking member body 3152 and a sealing ring 3154 sleeved on the outside of the blocking member body 3152; the blocking member body 3152, the blocking member 315 and the supporting portion 316 are integrally formed; the sealing ring 3154 is sleeved on the outside of the blocking member body 3152 to interference fit with the follow-up component 330.

[0394] Referring to Figures 74 and 75 , in one embodiment, a curved and extending ventilation groove 3142a is formed on the outer surface of the top cover sidewall. One end of the ventilation groove 3142a connects to an end of the top cover sidewall away from the liquid storage chamber 310a, and the other end of the ventilation groove 3142a curves and extends to the middle of the top cover sidewall. A ventilation hole 3142b is formed on the bottom wall of the ventilation groove 3142a, which connects to the liquid storage chamber 310a. The ventilation groove 3142a and the ventilation hole 3142b together form a ventilation channel, so that air outside the top cover 3142 can enter the liquid storage chamber 310a through the ventilation channel. Furthermore, the top cover sidewall is also provided with a sealing rib 3142c protruding around the ventilation groove 3142a. The sealing rib 3142c can abut against the atomizer bracket 312 to seal the ventilation channel.

[0395] In another embodiment, as shown in FIG77 , the top wall of the top cover is provided with an air inlet 3142d connected to the liquid storage chamber 310a. The atomizer assembly 310 further includes a ventilation valve 3146, which is rotatably mounted on the top cover 3142. The ventilation valve 3146 is located within the liquid storage chamber 310a and covers the air inlet 3142d. Thus, when the external atmospheric pressure is greater than the air pressure within the liquid storage chamber 310a, the external atmospheric pressure pushes the ventilation valve 3146 to rotate to open the air inlet 3142d, allowing external air to flow into the liquid storage chamber 310a through the air inlet 3142d. When the force exerted on the ventilation valve plate 3146 by the oil film adsorption force, the oil smoke gravity and the air pressure in the liquid storage chamber 310a is equal to the force exerted on the ventilation valve plate 3146 by the external atmospheric pressure, the ventilation valve plate 3146 re-covers the air inlet hole 3142d to close the liquid storage chamber 310a, thereby realizing the one-way conduction function.

[0396] Continuing with Figures 72 and 73, the metering assembly 330 includes an outer ring housing 331, an inner ring housing 332, and a sealing cap 333. The outer ring housing 331 is a hollow cylindrical structure with one end open, and its central axis extends along a first direction. The inner ring housing 332 extends from the closed end of the outer ring housing 331 along the first direction to the open end of the outer ring housing 331. An outlet passage 230b extending along the first direction is formed within the inner ring housing 332, and one end of the outlet passage 230b extends through the closed end of the outer ring housing 331 to communicate with the outside atmosphere. The sealing cap 333 is formed of a puncturable structure such as a metal film. The sealing cap 333 is mounted on the open end of the outer ring housing 331 and fits over the inner ring housing 332.

[0397] Thus, the outer ring shell 331, the inner ring shell 332, and the sealing cover 333 collectively form a further metering chamber 230a that circumferentially surrounds the inner ring shell 332. When the further metering assembly 330 is mounted on the atomizer bracket 312, the conducting member 313 pierces the sealing cover 333. The abutting portion 316, pushed by the sealing cover 333, moves the blocking member 315 to open the liquid inlet channel 313a.

[0398] In a preferred embodiment, the sealing cover 333 is provided with two puncture areas, each of which has an edge corresponding to an edge of the conductive member 313. The thickness of the edge of the puncture area is thinner than that of the other areas of the sealing cover 333, allowing it to be easily pierced by the conductive member 313. The center of the puncture area corresponds to the blocking member 315, and this area is thicker, thus pushing the conductive member 313 downward to open the liquid inlet channel 313a.

[0399] As shown in Figures 76 and 77, two guide rails 3312 are projected from the outer wall of the continue assembly 330. The two guide rails 3312 are located on opposite sides of the continue assembly 330 along a radial direction of the continue assembly 330, and each guide rail 3312 extends longitudinally along a first direction. The atomizer bracket 312 defines two guide grooves 3112a. The two guide grooves 3112a are located on opposite sides of the atomizer bracket 312 along a radial direction of the atomizer bracket 312, and each guide groove 3112a extends longitudinally along the first direction. It will be understood that the number of guide rails 3312 and guide grooves 3112a is not limited and can be provided as needed to meet different requirements.

[0400] Based on the arrangement of the guide rail 3312 and the guide groove 3112a, the electronic atomization device 300 has a first installation state and a second installation state. When the electronic atomization device 300 is in the first installation state, one end of the guide rail 3312 abuts against the edge of the atomization bracket 312, and the atomization assembly 310 and the follow-up assembly 330 can rotate relative to each other. When the guide rail 3312 is aligned with the guide groove 3112a, the follow-up assembly 330 is provided with one end of the guide rail 3312 which can be inserted into the atomization assembly 310 along the first direction, and the guide rail 3312 is inserted into the guide groove 3112a along the first direction, thereby limiting the relative position of the atomization assembly 310 and the follow-up assembly 330 in the circumferential direction, ensuring that the puncture area of ​​the conductive member 313 and the sealing cover 333 are accurately aligned.

[0401] In some embodiments, the outer wall of the refill component 330 is further provided with at least one elastic buckle 3314, and the inner wall of the atomizer bracket 312 is provided with at least one snap-fitting groove matching the elastic buckle 3314. When the refill component 330 is installed on the atomizer component 310, the elastic buckle 3314 can be engaged in the snap-fitting groove to fix the refill component 330 and the atomizer component 310 relative to each other.

[0402] As a preferred embodiment, the length of the guide rail 3312 is greater than the height of the conductive member 313 protruding from the bracket body 311. When one end of the guide rail 3312 is against the edge of the atomizer bracket 312, the distance between the end face of the continue component 330 for contacting the atomizer component 310 and the end face of the atomizer component 310 for contacting the continue component 330 is greater than the protruding height of the conductive member 313. The end of the conductive member 313 facing the sealing cover 333 is in a suspended state, thereby preventing the sealing cover 333 and the conductive member 313 from contacting each other during the relative rotation of the continue component 330 and the guide rail 3312, while ensuring that the conductive member 313 can be fully inserted into the continue component 330.

[0403] In some embodiments, a sealing ring 336 is embedded in the outer ring shell 331 of the metering assembly 330. When the metering assembly 330 is installed on the atomizing assembly 310, the sealing ring 336 forms an interference fit with the inner wall of the atomizing bracket 312 to close the gap between the two. As a preferred embodiment, the inner sidewall of the bracket body 311 of the atomizing bracket 312 forms a circumferentially extending avoidance groove 3112b. When one end of the guide rail 3312 abuts the edge of the atomizing bracket 312, the portion of the sealing ring 336 protruding from the outer ring shell 331 is located within the avoidance groove 3112b, thereby allowing the atomizing assembly 310 and the metering assembly 330 to rotate freely relative to each other, facilitating the mutual insertion of the guide rail 3312 and the guide groove 3112a.

[0404] As shown in Figures 74 and 80, the battery assembly 320 includes a battery holder 321, a bottom cover 322, a battery 323, a mainboard 324, a sensing unit 325, an airway liquid suction piece 326, and a conductive ejector pin 327. The battery holder 321 is a hollow shell-like structure. One end of the battery holder 321 is connected to the end of the atomizer assembly 310 away from the refill assembly 330. A battery accommodating cavity and an air inlet duct are formed adjacent to each other within the battery holder 321. A holder air inlet 321a is provided to connect the air inlet duct with the atomizer assembly 310. The bottom cover 322 is connected to the end of the battery holder 321 away from the atomizer assembly 310. A mainboard accommodating cavity is formed between the battery holder 321 and the bottom cover 322. The bottom cover 322 is provided with a bottom cover air inlet hole to connect the mainboard accommodating cavity with the external atmosphere. The main board 324 and the sensing unit 325 are both housed in the main board 324 housing cavity, the battery 323 is housed in the battery 323 housing cavity, the airway liquid suction piece 326 is housed in the air inlet duct, and the conductive ejector pin 327 is inserted into one end of the battery bracket 321 facing the atomizer assembly 310 and is electrically connected to the battery 323.

[0405] In this way, the battery 323 is electrically connected to the heating element 3143 of the atomizer assembly 310 through the conductive ejector pin 327. When the user inhales the electronic atomizer device 300, the airflow in the external atmosphere passes through the air inlet hole of the bottom cover 322, the accommodating cavity of the mainboard 324, the air inlet duct, and the air inlet 321a of the bracket into the atomizer chamber 314a in sequence. During this process, the sensing unit 325 can sense the change in air pressure difference to send a sensing signal to the mainboard 324. The mainboard 324 can control the battery 323 to power the atomizer assembly 310 to heat the atomized medium according to the sensing signal.

[0406] In some embodiments, at least one positioning post 3212 is convexly provided on one end face of the battery holder 321 facing the atomizer assembly 310, and the atomizer base 3141 of the atomizer assembly 310 is also provided with a positioning hole that matches the positioning post 3212. When the atomizer assembly 310 and the battery assembly 320 are mated with each other, the positioning post 3212 is inserted into the positioning hole, thereby achieving circumferential positioning of the atomizer base 3141 and the battery holder 321. Furthermore, at least one magnetic member 3214 is embedded in one end face of the battery holder 321 facing the atomizer assembly 310, and the magnetic member 3214 can adsorb the atomizer base 3141 to connect the battery holder 321 and the atomizer base 3141 to each other.

[0407] The connection principle of the atomizing assembly 310 and the continuing assembly 330 of the third embodiment is as follows:

[0408] Before the refill assembly 330 is installed on the atomizer assembly 310, the blocking member 315 is inserted into the liquid inlet channel 313a in the atomizer assembly 310, and the second blocking portion 3154 of the blocking member 315 blocks the liquid inlet channel 313a. In the refill assembly 330, the sealing cover 333 seals the refill chamber 230a.

[0409] When installing the further metering assembly 330 on the atomizer assembly 310, first insert one end of the further metering assembly 330 into the atomizer assembly 310, with one end of the guide rail 3312 resting against the edge of the atomizer bracket 312. Then, rotate the atomizer assembly 310 and the further metering assembly 330 relative to each other in the circumferential direction. When the guide rail 3312 is aligned with the guide groove 3112a, the further metering assembly 330 can be further inserted into the atomizer assembly 310. During the process of mutual insertion of the guide rail 3312 and the guide groove 3112a, the first conducting portion 3132, the blocking piece 315, and the second conducting portion 3134 successively pierce the sealing cover 333 of the further metering component 330, and the blocking piece 315 moves under the push of the sealing cover 333. The second blocking portion 3154 is pushed away from the liquid inlet channel 313a and enters the liquid storage chamber 310a by the further metering component 330. There is a gap between the first blocking portion 3152 and the wall of the liquid inlet channel 313a, and the atomized medium in the further metering chamber 230a flows into the liquid storage chamber 310a from between the first blocking portion 3152 and the wall of the liquid inlet channel 313a.

[0410] The above-mentioned electronic atomization device 100 / 200 / 300, by providing a detachable refilling component 130 / 230 / 330, allows the atomization component 110 / 210 / 310 and the refilling component 130 / 230 / 330 to be transported and stored separately. Not only is it not easy to leak during transportation and storage, but the refilling component 130 / 230 / 330 can be installed on the atomization component 110 / 210 / 310 so that the liquid storage chamber 110a / 210a / 310a of the atomization component 110 / 210 / 310 is synchronously connected to the refilling chamber 130a / 230a / 330a of the refilling component 130 / 230 / 330. While improving the convenience of use and the recycling rate of the electronic atomization device 100 / 200 / 300, it effectively prevents the liquid storage chamber 110a / 210a / 310a from leaking under the action of external atmospheric pressure at the moment of opening.

[0411] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
