Description

Technical Field

[0001] The present invention relates to the technical field of atomization devices, and in particular to an electronic atomization device. Background Art

[0002] Conventional electronic atomization devices primarily consist of an atomizer and a power supply. The atomizer typically includes a liquid reservoir for storing atomizable medium and an atomizing assembly for heating and atomizing the atomizable medium to form an aerosol for the user. The power supply provides energy to the atomizer.

[0003] Traditional atomizers typically pre-fill the liquid reservoir with atomizer matrix. However, during transportation, the atomizer matrix in the reservoir can easily seep into the atomizer core, causing oil leakage. To prevent leakage, the atomizer core and the liquid reservoir are usually isolated before use. This ensures that the ceramic is dry and oil-free before use. Accidental triggering of the microphone during use or during production can cause dry heating of the ceramic and damage the device. Summary of the Invention

The side of the sealing seat 2 away from the liquid storage cavity 11 forms a mounting cavity 12 for accommodating the plug-in portion 411 with the inner wall of the nebulizer housing 1. In a preferred embodiment, the inner diameter of the liquid storage cavity 11 is smaller than the inner diameter of the mounting cavity 12, so that a first step 14 is formed at the connection between the liquid storage cavity 11 and the mounting cavity 12. The sealing seat 2 is accommodated in the mounting cavity 12 and abuts against the first step 14.

[0038] See also Figure 5 , Figure 5: It is a structural schematic diagram of the sealing seat in the electronic atomization device provided by the present invention. In this embodiment, an air outlet 21 and a mounting hole 22 are provided on the sealing seat 2. The air outlet 21 and the mounting hole 22 are arranged at intervals, and the air outlet 21 and the mounting hole 22 respectively extend from the side surface of the sealing seat 2 forming the liquid storage chamber 11 to the side surface opposite thereto. The position of the mounting hole 22 corresponds to the position of the plug-in portion 411, and the mounting hole 22 is used to install the plug-in portion 411 so that the end of the plug-in portion 411 blocks the liquid storage chamber 11 to prevent the matrix to be atomized in the liquid storage chamber 11 from leaking out of the mounting hole 22. The position of the air outlet 21 corresponds to the position of the air outlet channel 13, and the air outlet 21 is used to connect and communicate with the end of the air outlet channel 13.

In this embodiment, there are two mounting holes 22, symmetrically arranged around the air outlet 21. There is only one air outlet 21, and the central axis of the air outlet 21 coincides with the central axis of the sealing seat 2. The shape of the port of the air outlet channel 13 connected to the air outlet 21 matches the shape of the air outlet 21, allowing the air outlet channel 13 to be inserted into the air outlet 21.

[0039] See also Figure 6 , Figure 6 : This is a schematic diagram of the structure of the blocking member in the electronic atomization device provided by the present invention.

[0040] See also Figure 7 , Figure 7 This is a schematic diagram of the power supply assembly in the electronic atomization device provided by the present invention. A lower liquid channel 42 is provided at one end of the base 41. This lower liquid channel 42 is slidably inserted into the mounting cavity 12. The lower liquid channel 42 is part of the aforementioned plug-in portion 411. The base 41 has an installation space 427 that communicates with the lower liquid channel 42.

[0041] In one embodiment, the first end of the lower liquid channel 42 is fixedly connected to the base 41 and communicates with the mounting space 427. The second end of the lower liquid channel 42 is slidably inserted into the mounting hole 22. The second end of the lower liquid channel 42 is inserted into different positions of the mounting hole 22 to connect or block the lower liquid channel 42 from the liquid storage chamber 11. In this embodiment, the lower liquid channel 42 is provided at the end of the base 41 and is integrally formed with the base 41. In a specific embodiment, the end of the lower liquid channel 42 away from the base 41 is sealed by the bottom wall and at least one liquid inlet 422 is opened on the side wall; when the second end of the lower liquid channel 42 is inserted into the first position at the end of the liquid storage chamber 11, the lower liquid channel 42 and the liquid storage chamber 11 are separated by the bottom wall; when the second end of the lower liquid channel 42 is inserted into the second position at the end of the liquid storage chamber 11, the lower liquid channel 42 and the liquid storage chamber 11 are connected through the liquid inlet 422, so that the matrix to be atomized in the liquid storage chamber 11 reaches the atomizing core 44 through the lower liquid channel 42. In this embodiment, two liquid inlets 422 are provided on the lower liquid channel 42, and the two liquid inlets 422 are provided on the side wall of the lower liquid channel 42 facing away from each other. The sizes of the two liquid inlets 422 can be the same or different. Among them, the length of the side parallel to the central axis of the liquid inlet 422 and the lower liquid channel 42 is 0.5 mm to 50 mm; the length of the side perpendicular to the central axis of the liquid inlet 422 and the lower liquid channel 42 is 0.5 mm to 30 mm, and the endpoints of the above range may include this number or not.

[0042] In this embodiment, the second end of the lower liquid channel 42 is inserted into the first position at the port of the liquid storage chamber 11, and the liquid inlet 422 of the lower liquid channel 42 is completely covered by the inner wall surface of the mounting hole 22. The bottom wall of the lower liquid channel 42 blocks the mounting hole 22, so that the matrix to be atomized in the liquid storage chamber 11 cannot be transferred to the atomizer core 44. When the second end of the lower liquid channel 42 is inserted into the second position at the port of the liquid storage chamber 11, the liquid inlet 422 of the lower liquid channel 42 is partially exposed to the liquid storage chamber 11, and the matrix to be atomized in the liquid storage chamber 11 can be transferred to the atomizer core 44 through the lower liquid channel 42. In this embodiment, there are two lower liquid channels 42 and they are respectively provided with two mounting holes 22, and the liquid inlets 422 provided on the two lower liquid channels 42 are oriented in different directions. In a specific embodiment, the liquid inlets 422 provided on the two lower liquid channels 42 are oriented in opposite directions.

[0043] In this embodiment, a ventilation groove 423 is provided on the outer wall of the lower liquid channel 42, and the inner wall surface of the mounting hole 22 covers the ventilation groove 423 to form a ventilation channel. One end of the ventilation channel extends to the outer wall of the base 41 for communication with the outside world; the other end of the ventilation channel extends to a position corresponding to the liquid inlet 422, so that when the liquid inlet 422 of the lower liquid channel 42 is partially exposed to the liquid storage chamber 11, the end of the ventilation groove 423 close to the liquid storage chamber 11 is exposed to the liquid storage chamber 11, and the end of the ventilation groove 423 exposed to the liquid storage chamber 11 connects the liquid storage chamber 11 with the ventilation channel. When the air pressure in the liquid storage chamber 11 is lower than the external atmospheric pressure, external air can enter the liquid storage chamber 11 through the ventilation channel to balance the air pressure between the liquid storage chamber 11 and the external atmosphere. When the liquid inlet 422 of the lower liquid channel 42 is completely covered by the inner wall of the mounting hole 22, the end of the ventilation groove 423 near the liquid storage chamber 11 is completely covered by the end of the mounting hole 22, thereby isolating the end of the ventilation channel near the liquid storage chamber 11 from the liquid storage chamber 11. During the process of transferring the atomized substrate in the liquid storage chamber 11 through the liquid inlet 422 to the atomizer core 44, the ventilation groove 423 serves to balance the air pressure between the liquid storage chamber 11 and the outside atmosphere, preventing the phenomenon of liquid flow being blocked due to the pressure in the liquid storage chamber 11 being lower than the outside atmospheric pressure. The width of the ventilation groove 423 is 0.1 mm to 10 mm, and the depth of the ventilation groove 423 is 0.05 mm to 1 mm. The endpoints of the above ranges may include or exclude these numbers. In a preferred embodiment, the end of the ventilation groove 423 near the liquid storage chamber 11 is located at the same height as the side of the liquid inlet 422 near the liquid storage chamber 11. The extension direction of the ventilation groove 423 may be parallel to the central axis of the electronic atomization device 100. In another optional embodiment, the ventilation groove 423 may also be spirally arranged on the outer wall surface of the lower liquid channel 42.

[0044] In this embodiment, an exhaust groove 424 is provided on the outer wall of the lower liquid channel 42. The exhaust groove 424 is spaced apart from the ventilation groove 423. One end of the exhaust groove 424 extends to the end of the lower liquid channel 42 away from the base 41 and is in communication with the liquid storage chamber 11. When the liquid inlet 422 of the lower liquid channel 42 is completely covered by the inner wall surface of the mounting hole 22, the inner wall surface of the mounting hole 22 completely covers the exhaust groove 424. The exhaust groove 424 is provided on the outer wall of the lower liquid channel 42 to prevent excessive air pressure in the liquid storage chamber 11 during the process of the lower liquid channel 42 being slidably inserted into the mounting hole 22, thereby preventing the air in the liquid storage chamber 11 from being overly compressed and causing leakage.

[0045] In this embodiment, a first connecting portion 15 is provided on the inner wall of the mounting cavity 12, and a second connecting portion 425 is provided on the outer wall of the base 41. The base 41 is fixedly connected to the atomizer housing 1 through the first connecting portion 15 and the second connecting portion 425 to prevent the base 41 from being separated from the atomizer housing 1.

[0046] In this embodiment, the first connecting portion 15 includes a chute 16, the orientation of which is consistent with the direction in which the lower liquid channel 42 is inserted into the mounting cavity 12. The second connecting portion 425 includes a slider 426. When the slider 426 is at the end of the chute 16 away from the liquid storage cavity 11, the second end of the lower liquid channel 42 is inserted into a first position at the end of the liquid storage cavity 11. When the slider 426 is at the end of the chute 16 near the liquid storage cavity 11, the second end of the lower liquid channel 42 is inserted into a second position adjacent to the end of the liquid storage cavity 11. In another specific embodiment, the first connecting portion 15 also includes a slot 17, which is disposed on a side of the chute 16 near the liquid storage cavity 11 and in the direction in which the chute 16 extends. The slot 17 is spaced apart from the chute 16. When the slider 426 slides into the slot 17, the second end of the lower liquid channel 42 is fixedly inserted into the second position at the end of the liquid storage cavity 11, and the liquid inlet 422 of the lower liquid channel 42 is connected to the liquid storage cavity 11.

[0047] In another optional embodiment, the second connecting portion 425 includes a chute 16, the direction of which the chute 16 is arranged to coincide with the direction in which the lower liquid channel 42 is inserted into the mounting cavity 12. The first connecting portion 15 includes a slider 426. When the slider 426 is at the end of the chute 16 near the liquid storage cavity 11, the second end of the lower liquid channel 42 is inserted into a first position at the end of the liquid storage cavity 11. When the slider 426 is at the end of the chute 16 away from the liquid storage cavity 11, the second end of the lower liquid channel 42 is inserted into a second position adjacent to the end of the liquid storage cavity 11. In another specific embodiment, the second connecting portion 425 also includes a slot 17. The slot 17 is arranged on the side of the chute 16 away from the liquid storage cavity 11 and in the direction in which the chute 16 extends. The slot 17 is spaced apart from the chute 16. When the slider 426 slides into the slot 17, the second end of the lower liquid channel 42 is fixedly inserted into the second position at the end of the liquid storage cavity 11, and the liquid inlet 422 of the lower liquid channel 42 is connected to the liquid storage cavity 11.

[0048] In another specific embodiment, a limiting portion 428 is provided on the outer wall of the base 41, and the limiting portion 428 is provided on the side of the second connecting portion 425 away from the lower liquid channel 42 and is spaced apart from the second connecting portion 425. When the limiting portion 428 abuts against the end of the atomizer housing 1, the slider 426 is at the end of the slide groove 16 away from the liquid storage chamber 11, so that the position of the second end of the lower liquid channel 42 inserted at the port of the liquid storage chamber 11 is limited to the first position. Specifically, the limiting portion 428 includes a baffle, a first end of the baffle is fixedly connected to the base 41, and a second end of the baffle is spaced apart from the outer wall of the base 41. When the second end of the baffle abuts the end of the atomizer housing 1, the second end of the lower liquid channel 42 is inserted at a first position at the port of the liquid storage chamber 11, and the liquid inlet 422 of the lower liquid channel 42 is separated from the liquid storage chamber 11. When the end of the atomizer housing 1 is between the baffle and the base 41, the second end of the lower liquid channel 42 is inserted at a position at the port of the liquid storage chamber 11 away from the first position, and the liquid inlet 422 of the lower liquid channel 42 is connected to the liquid storage chamber 11.

[0049] In this embodiment, a first air inlet channel 5 is formed between the plug-in portion 411 and the inner wall of the mounting cavity 12. Specifically, the first air inlet channel 5 is formed between the inner wall of the mounting cavity 12 and the outer wall of the portion of the base 41 inserted into the mounting cavity 12. In some embodiments, the inlet end of the first air inlet channel 5 is connected to the outside atmosphere, and the outlet end of the first air inlet channel 5 is connected to the outlet channel 13. When the second end of the lower liquid channel 42 is fixedly inserted in the first position at the end of the liquid storage cavity 11, the inlet end of the first air inlet channel 5 is connected to the outside atmosphere. In this case, when suction is drawn through the outlet channel 13, it is equivalent to being directly connected to the outside atmosphere through the first air inlet channel 5. In other embodiments, the inlet end of the first air inlet channel 5 is connected to both the outside atmosphere and the atomizing cavity 452, and the outlet end of the first air inlet channel 5 is connected to the outlet channel 13. When the second end of the lower liquid channel 42 is fixedly inserted in the first position at the end of the liquid storage cavity 11, the inlet end of the first air inlet channel 5 is connected to both the outside atmosphere and the atomizing cavity 452. It can be understood that the advantage of this approach is that the first air inlet channel 5 can share a portion of the air flow channel with other channels, thereby improving space utilization and simplifying the structure. When the second end of the lower liquid channel 42 is fixedly inserted into the second position at the port of the liquid storage chamber 11, the air inlet end of the first air inlet channel 5 is isolated from the outside atmosphere, and the air inlet end of the first air inlet channel 5 is only connected to the atomizing chamber 452. In this embodiment, the power supply assembly 4 has an atomizing chamber 452 and a second air inlet channel 6, the air inlet end of the second air inlet channel 6 is directly connected to the outside atmosphere, and the air outlet end of the second air inlet channel 6 is connected to the atomizing chamber 452. An air flow sensor 462 is provided on the power supply assembly 4, and the air flow sensor 462 is used to start the battery 461 to power the atomizing core 44, so that the atomizing core 44 heats and atomizes the substrate to be atomized. The air flow sensor 462 is connected to the second air inlet channel 6 through the starting air channel 463 provided on the battery holder 46. In a preferred embodiment, the inner diameter of the end of the starting air passage 463 connected to the second air inlet passage 6 is smaller than the inner diameter of the end connected to the airflow sensor 462. In a specific embodiment, the power supply assembly 4 includes a battery holder 46, which is accommodated in the installation space 427.

[0050] In an optional embodiment, a first air inlet path is formed between the plug portion 411 and the inner wall of the mounting cavity 12. The air inlet end of the first air inlet path is directly connected to the outside atmosphere through the air inlet structure 18, and the air outlet end of the first air inlet path is connected to the air outlet channel 13. A second air inlet path is provided within the power supply assembly 4. The air inlet end of the second air inlet path is directly connected to the outside atmosphere, and the air outlet end of the second air inlet path is connected to the air outlet channel 13. The second air inlet path and the first air inlet path share a common airflow path, and the air outlet channel 13 communicates with the air outlet ends of the first air inlet path and the air outlet ends of the second path through the common airflow path. and only the second airflow path passes through the airflow sensor 462; wherein, when the atomizer housing 1 and the power supply assembly 4 are in a first connection state, the air outlet channel 13 is connected to the outside atmosphere through the first airflow path and the second airflow path respectively, and the airflow on the second airflow path is insufficient to activate the airflow sensor 462; when the atomizer housing 1 and the power supply assembly 4 are in a second connection state, the air outlet channel 13 is connected to the outside atmosphere only through the second airflow path, and the airflow on the second airflow path is sufficient to activate the airflow sensor 462. wherein, the plug-in portion 411 is inserted into different positions of the mounting cavity 12 so that the air outlet channel 13 is connected to the outside atmosphere through the first air inlet channel 5 or the second air inlet channel 6.

[0051] See also Figure 8 , Figure 8 Schematic diagram of the structure of the battery holder in the electronic atomization device provided by the present invention. In a specific embodiment, a battery 461 and an airflow sensor 462 are installed on the battery holder 46. The airflow sensor 462 is arranged on the side of the battery 461 close to the atomizer housing 1. An air inlet groove 464 is provided on the outer wall of the battery holder 46. The end of the air inlet groove 464 close to the liquid storage chamber 11 is connected to the atomization chamber 452, and the end of the air inlet groove 464 away from the liquid storage chamber 11 is directly connected to the outside atmosphere. The inner wall of the installation space 427 covers the air inlet groove 464 to form the above-mentioned second air inlet channel 6.

[0052] In one specific embodiment, the second air inlet channel 6 may include a first channel 61 and a second channel 62 connected to the first channel 61. The outlet of the first channel 61 is directly connected to the atomizing chamber 452, the inlet of the first channel 61 is directly connected to the outlet of the second channel 62, and the inlet of the second channel 62 is directly connected to the outside atmosphere. The starting air channel 463 is directly connected to the first channel 61. The second channel 62 is a Tesla valve structure, the inlet of the Tesla valve structure is connected to the outside atmosphere, and the outlet of the Tesla valve is connected to the inlet of the first channel 61. The portion between the inlet and outlet of the Tesla valve serves as an air guide. By configuring the second channel 62 as a Tesla valve structure, unimpeded air intake is facilitated during inhalation without affecting the air flow rate. During the inhalation process, some users have the habit of exhaling into the electronic atomizer device 100. The Tesla valve structure can prevent the airflow from being easily blown out of the bottom air inlet 456, or the blown aerosol has already largely condensed in the Tesla valve structure. When the liquid storage chamber 11 leaks or the atomization chamber 452 leaks, the Tesla valve structure helps to slow down or prolong the leakage time. If a small amount of liquid is leaked, it will be stored by the reverse structure of the Tesla valve and will not directly flow out of the electronic atomization device 100.

[0053] In a preferred embodiment, the bottom wall of the air inlet groove 464 forming the first channel 61 is lower than the bottom wall of the air inlet groove 464 forming the second channel 62, and the connection therebetween is a slope structure to facilitate the gas in the second channel 62 to be transferred to the first channel 61.

[0054] In an optional embodiment, the atomizer housing 1 has an air intake structure 18. When the partial base 41 inserted into the mounting cavity 12 is inserted into the first position of the mounting cavity 12, the air intake structure 18 facilitates the transmission of external atmosphere to the air intake end of the first air intake channel 5.

[0055] In one embodiment, a recessed portion 19 is provided on the inner wall of the mounting cavity 12 near the end of the mounting cavity 12. The recessed portion 19 serves as the air inlet structure 18. When the base 41 inserted into the mounting cavity 12 is in a first position, the first end of the recessed portion 19 communicates with the air inlet end of the first air inlet channel 5, and the second end of the recessed portion 19 communicates with the outside atmosphere. When the base 41 inserted into the mounting cavity 12 is in a second position, the recessed portion 19 is isolated from the air inlet end of the first air inlet channel 5 or the outside atmosphere. The outside atmosphere reaches the air outlet channel 13 only through the second air inlet channel 6 and the atomizing chamber 452. This facilitates the creation of a negative pressure state within the starting air channel 463 during inhalation, facilitating the airflow sensor 462 to activate the battery 461 to power the atomizing core 44. In one embodiment, the recessed portion 19 may be a groove. Among them, the radial dimension of the plug-in portion 411 of the base 41 is smaller than the radial dimension of other parts, so as to form a second step 429 on the base 41. When the plug-in portion 411 is inserted into the first outer portion of the installation cavity 12, the second end of the recessed portion 19 is spaced apart from the second step 429 and is connected to the outside atmosphere; when the plug-in portion 411 is inserted into the second outer portion of the installation cavity 12, the second end of the recessed portion 19 abuts against the second step 429 to be sealed by the second step 429, and the recessed portion 19 is separated from the air intake end of the first air intake channel 5 or from the outside atmosphere.

[0056] In another specific embodiment, a through hole (not shown) is provided on the side wall of the installation cavity 12 near the port of the installation cavity 12, and the through hole serves as an air intake structure 18; when the plug-in portion 411 is inserted in the first position of the installation cavity 12, the through hole is arranged corresponding to the air intake end of the first air intake channel 5, and the air intake end of the first air intake channel 5 is connected to the outside atmosphere; when the plug-in portion 411 is inserted in the second position of the installation cavity 12, the through hole is staggered with the air intake end of the first air intake channel 5 and is separated from the air intake end of the first air intake channel 5, and the outside atmosphere only reaches the air outlet channel 13 through the second air intake channel 6 and the atomization chamber 452.

[0057] In an optional embodiment, a sealing ring 43 is provided on the plug-in portion 411 of the base 41. The sealing ring 43 is used to abut against the inner wall of the installation cavity 12 when the plug-in portion 411 is inserted into the second outer portion of the installation cavity 12, thereby preventing the recessed portion 19 from being connected to the air inlet end of the first air inlet channel 5.

[0058] In a specific embodiment, the sealing ring 43 is disposed between the second connecting portion 425 and the limiting portion 428. When the second end of the lower liquid channel 42 is fixedly inserted in the first position at the end of the liquid storage chamber 11, the sealing ring 43 corresponds to the position of the recessed portion 19, and the sealing ring 43 and the recessed portion 19 cooperate to form an air intake space, so that the outside air can be transmitted to the air intake end of the first air intake channel 5 through the air intake space. When the second end of the lower liquid channel 42 is fixedly inserted in the second position at the end of the liquid storage chamber 11, the sealing ring 43 is tightly fitted with the inner wall surface of the mounting chamber 12, the recessed portion 19 slides to one side of the liquid storage chamber 11 and is corresponding to the outer wall of the base 41 on the side of the sealing ring 43 away from the liquid storage chamber 11, and the sealing ring 43 blocks the outside air from entering the air intake end of the first air intake channel 5. In a preferred embodiment, as the position of the second end of the lower liquid channel 42 fixedly inserted at the end of the liquid storage chamber 11 approaches from the first position to the second position, when the liquid inlet 422 provided on the lower liquid channel 42 begins to be exposed to the liquid storage chamber 11, the sealing ring 43 and the inner wall of the mounting cavity 12 adjacent to the recessed portion 19, which is close to the liquid storage chamber 11 and adjacent to the recessed portion 19, are tightly fitted together, thereby blocking the recessed portion 19 from providing external air to the first air inlet channel 5, and transmitting external air to the air outlet channel 13 only through the second air inlet channel 6. When the liquid storage chamber 11 is connected to the atomizer core 44 through the liquid inlet 422, the substrate to be atomized stored in the liquid storage chamber 11 is transmitted to the atomizer core 44, so that the atomizer core 44 is loaded with the substrate to be atomized first when the user draws, thereby avoiding the phenomenon of the atomizer core 44 being dry-burned after the airflow sensor 462 is activated when the user draws.

[0059] In a specific embodiment, the electronic atomization device 100 further includes a mounting seat 45, which is accommodated in the mounting space 427. Specifically, the mounting seat 45 is accommodated in the portion of the mounting space 427 close to the lower liquid channel 42, that is, the mounting seat 45 is located on the side of the battery holder 46 close to the liquid storage chamber 11. The mounting seat 45 has a receiving chamber 451 therein, and the receiving chamber 451 is used to accommodate the atomizer core 44. The mounting seat 45 includes an upper seat body 453 and a lower seat body 455 fixedly connected to the upper seat body 453. The upper seat body 453 and the lower seat body 455 cooperate to form the receiving chamber 451. The atomizer core 44 is arranged in the receiving chamber 451 and the atomizer core 44 is in close contact with the upper seat body 453. The atomizer core 44 and part of the inner wall of the receiving chamber 451 form the above-mentioned atomizer chamber 452. The lower seat body 455 is provided with an air inlet hole 456, and the air inlet hole 456 is connected to the second air inlet channel 6. In this embodiment, a window 454 is provided on the upper body 453, through which a portion of the surface of the atomizer core 44 is exposed, so that the lower liquid channel 42 is connected to the atomizer core 44 through the window 454. In one specific embodiment, the lower body 455 is integrally formed with the battery holder 46 for mounting the battery 461. An air inlet 456 is provided on the surface of the lower body 455 opposite the atomizer core 44. The air inlet 456 is used to transmit external air to the atomizer chamber 452. The material of the upper body 453 is at least one of silicone, rubber, and plastic.

[0060] See also Figures 9 to 12 , Figure 9 is a cross-sectional view of the electronic atomization device at a first angle when the lower liquid pipe provided by the present invention is in a first position; Figure 10 is a cross-sectional view of the electronic atomization device at a second angle when the lower liquid pipe provided by the present invention is in the first position; Figure 11 is a cross-sectional view of the electronic atomization device at a first angle when the lower liquid pipe provided by the present invention is in a second position; Figure 12This is a cross-sectional view of the electronic atomization device provided by the present invention when the lower liquid pipe is in the first position at a second angle. In a specific embodiment, when the electronic atomization device 100 is in a transport or unused state, the second end of the lower liquid channel 42 is fixedly inserted in the first position at the end of the liquid storage chamber 11. At this time, the end of the atomizer housing 1 close to the base 41 is in contact with the end of the baffle close to the liquid storage chamber 11. The slider 426 on the base 41 is at the end of the slide 16 away from the liquid storage chamber 11. The liquid inlet 422 on the lower liquid channel 42 is completely covered by the inner wall of the mounting hole 22, and the liquid storage chamber 11 and the atomization core 44 are in a partitioned state. The air inlet end of the first air inlet channel 5 is connected to the outside atmosphere through the recessed portion 19. The air inlet end of the first air inlet channel 5 is also connected to the atomization chamber 452. The air inlet end of the second air inlet channel 6 is directly connected to the outside atmosphere. The air outlet end of the second air inlet channel 6 is connected to the atomization chamber 452, and then connected to the air outlet channel 13 through the first air inlet channel 5. When the electronic atomization device 100 needs to be used, the baffle is bent or broken in the direction away from the base 41, and the power supply assembly 4 is inserted in the direction close to the atomizer housing 1, so that the end of the atomizer housing 1 close to the base 41 abuts against the second step 429, and the slider 426 on the base 41 is in the slot 17 on the inner wall of the mounting cavity 12, so that the second end of the lower liquid channel 42 is fixedly inserted in the second position at the port of the liquid storage cavity 11. At this time, the lower liquid port on the lower liquid channel 42 is completely exposed to the liquid storage cavity 11, the liquid storage cavity 11 is connected to the atomization core 44, and the matrix to be atomized in the liquid storage cavity 11 is transferred to the atomization core 44 and loaded and atomized. At the same time, the mounting cavity 12 is provided with a recessed portion 19 and the inner wall of one side close to the liquid storage cavity 11 is tightly fitted with the outer wall of the sealing ring 43 to prevent the outside atmosphere from entering the air inlet end of the first air inlet channel 5 through the recessed portion 19. The electronic atomization device 100 transmits external gas to the atomization chamber 452 and the air outlet channel 13 only through the second air inlet channel 6. When the user inhales, the user inhales the gas in the electronic atomization device 100 into the mouth, and the gas in the starting airway 463 is also extracted, so that the air pressure in the starting airway 463 is in a negative pressure state. The airflow sensor 462 activates the battery 461 to power the atomization core 44, so that the atomization core 44 heats the loaded substrate to be atomized, and at the same time, the external gas also enters the electronic atomization device 100 through the air inlet end of the second air inlet channel 6, so that the external atmosphere is transmitted to the atomization chamber 452 through the second air inlet channel 6, and the aerogel obtained by atomization of the atomization core 44 is taken away from the atomization chamber 452, so that the aerogel is carried by the gas to the air outlet channel 13, and then enters the user's mouth.

[0061] The electronic atomization device provided in this embodiment includes an atomizer housing, a base, and an atomizer core. A lower liquid channel is provided at one end of the base so that the lower liquid channel can be slidably inserted into different positions of the mounting cavity in the atomizer housing, and then the connection or isolation between the atomizer core and the liquid storage cavity is controlled and adjusted by the lower liquid channel. Controlling the isolation between the atomizer core and the liquid storage cavity can prevent the electronic atomization device from leaking during transportation, with a simple structure and convenient operation. A first air inlet channel is formed between the plug-in portion and the inner wall of the mounting cavity, and a second air inlet channel is provided in the power supply assembly so that the airflow sensor is connected to the second air inlet channel. By inserting the plug-in portion at different positions in the mounting cavity, the air inlet end of the first air inlet channel can be connected or isolated from the outside atmosphere. When the air inlet end of the first air inlet channel is connected to the outside atmosphere, the airflow in the second air inlet channel is insufficient to activate the airflow sensor, thereby avoiding the phenomenon of false triggering of the airflow sensor. When the airflow sensor needs to be triggered, the air inlet end of the first air inlet channel is isolated from the outside atmosphere, so that the airflow in the second air inlet channel activates the airflow sensor, which is simple to operate and convenient to control.
