[0002] In the design of the conventional electronic atomization device, the tobacco tar is in direct contact with the oil absorbing cotton in the heating device before use. In general, the electronic atomization device needs to be transported over a long distance before reaching the consumer. The tobacco tar is in direct contact with the oil absorbing cotton during the long transportation process, which can easily lead to oxidation, deterioration or excessive oxidation and unnecessary chemical reactions, thus reducing the quality of the tobacco tar and even producing harmful substances to affect the safety of the atomized vapor and increase the health risks.

[0003] In addition, the retention of the tobacco tar between the oil storage chamber and the oil absorbing cotton can corrode the metal heating element in the oil absorbing cotton, thus reducing the conductivity and heating efficiency of the heating element. Furthermore, although the circuit part of the electronic atomization device is generally less in contact with the tobacco tar, the tobacco tar can penetrate into the circuit through the part with poor sealing in the bumpy road environment, thus causing short circuit or corrosion, affecting the atomization effect and service life of the electronic cigarette, and further affecting the user experience.

[0033] Referring to Figures 1-3 The utility model provides a kind of electronic atomization device 100, including shell 1 and the annular sealing member 2 and atomization core component 3 being arranged in shell 1, annular sealing member 2 will shell 1 inside be divided into oil storage space 21 and sliding space 22, atomization core component 3 includes atomization support 31, atomization support 31 is set through annular sealing member 2, atomization support 31 one end extends into oil storage space 21, the other end extends into sliding space 22;Shell 1 is close to the side of sliding space 22 and is provided with through-hole 11, electronic atomization device 100 further includes movable bottom sealing member 4, bottom sealing member 4 is fixedly connected with the one end of atomization support 31 extending into sliding space 22;Atomization support 31 is provided with oil inlet hole 311, annular sealing member 2 isolates oil inlet hole 311 with oil storage space 21, when bottom sealing member 4 is moved towards the side close to oil storage space 21, bottom sealing member 4 drives atomization support 31 to move, when bottom sealing member 4 moves to through-hole 11, oil inlet hole 311 is away from annular sealing member 2 and is communicated with oil storage space 21.

[0034] It can be understood that annular sealing member 2 divides the internal space of shell 1 into oil storage space 21 and sliding space 22, which effectively isolates oil storage space 21 from sliding space 22 to prevent leakage of tobacco tar; in combination with the pushing action of bottom sealing member 4, it can ensure that good sealing can be maintained when adjusting oil inlet hole 311, reducing the risk of oil leakage; by pushing bottom sealing member 4, oil inlet hole 311 can be away from annular sealing member 2, and then communicated with oil storage space 21, bottom sealing member 4 is fixedly connected with the one end of atomization support 31 extending into sliding space 22, and bottom sealing member 4 seals sliding space 22, so that the user only needs to easily push bottom sealing member 4 when using electronic atomization device 100, and the operation is more intuitive and simple; before electronic atomization device 100 is not used, annular sealing member 2 isolates oil inlet hole 311 from oil storage space 21, reducing the risk of problems such as immersion corrosion and leakage during transportation, and thus prolonging the service life of the entire electronic atomization device 100.

[0035] Specifically, shell 1 is the external frame of the entire electronic atomization device 100, for accommodating and supporting various internal components, shell 1 can be provided in the shape of an elongated cylinder or the like, so that annular sealing member 2 divides the space inside shell 1 into oil storage space 21 and sliding space 22, preventing tobacco tar from leaking from oil storage space 21 to sliding space 22, ensuring the sealing of the device, and oil storage space 21 is arranged above sliding space 22.

[0036] Shell 1 is provided with through-hole 11 on the side close to sliding space 22, through-hole 11 is butt-jointed with bottom sealing member 4, so that bottom sealing member 4 can be pushed as needed, and then the position of oil inlet hole 311 of atomization support 31 is adjusted, thereby controlling the communication between oil storage space 21 and oil inlet hole 311.

[0037] As Figure 2 shown in the cross-sectional schematic diagram of the electronic atomization device 100, the bottom sealing piece 4 is not completely pushed into the sliding space 22. Figure 1 As Figure 2 shown: the oil inlet hole 311 is blocked by the annular sealing piece 2, and does not form a communication state with the oil storage space 21.

[0038] As Figure 3 shown in the cross-sectional schematic diagram of the electronic atomization device 100, the bottom sealing piece 4 is not completely pushed into the sliding space 22. Figure 2 As Figure 3 shown: the oil inlet hole 311 is exposed, and forms a communication state with the oil storage space 21. In this state, the tobacco tar in the oil storage space 21 enters the inside of the atomization support 31 through the oil inlet hole 311, and the electronic atomization device 100 can start heating to atomize the tobacco tar.

[0039] The annular sealing piece 2 is set in a circular ring shape, and its inner and outer diameters are adaptively set according to the size of the space inside the shell 1 and the outer diameter of the atomization support 31. The outer wall of the circular ring directly contacts the shell 1, and the inner wall directly contacts the atomization support 31, which isolates the oil inlet hole 311 from the oil storage space 21 when the bottom sealing piece 4 is not pushed. The annular sealing piece 2 is made of a silicon or rubber material with elasticity, so as to ensure that the annular sealing piece 2 maintains good elasticity and sealing performance during long-term use.

[0040] The atomization support 31 penetrates the annular sealing piece 2, and is a part of supporting and fixing the atomization core assembly 3. The atomization support 31 partially extends into the oil storage space 21, and is used to transport tobacco tar from the oil storage space 21 to the atomization core. Part of the atomization support 31 extends into the sliding space 22, and is used to cooperate with the bottom sealing piece 4 to realize that when the bottom sealing piece 4 seals the through hole 11, the atomization support 31 is pushed, and the oil inlet hole 311 on the atomization support 31 sealed by the annular sealing piece 2 is exposed.

[0041] The oil inlet hole 311 is set on the side surface of the atomization support 31, and is a small circular or oval opening. The number and diameter of the oil inlet hole 311 can be set according to the demand for the amount of tobacco tar in the oil storage space 21, and are not specifically limited in the present application.

[0042] Further, referring to Figures 4-5 , a step 12 is arranged on the inner wall of the shell 1 corresponding to the annular sealing piece 2, and the annular sealing piece 2 is provided with a limiting block 23 corresponding to the step 12.

[0043] It can be understood that the limiting block 23 cooperates with the step 12 formed by the inner wall of the shell 1 to prevent the atomization support 31 from being pushed by the bottom seal 4, and the annular sealing silica gel is also moved upward to the oil storage space 21 side, so that the annular seal 2 remains in a fixed position, maintains the sealing property of the annular seal 2, the limiting block 23 avoids excessive friction between the annular seal 2 and the inner wall of the shell 1 or the atomization support 31, maintains the elasticity and durability of the annular seal 2, and the step 12 provides positioning when the annular seal 2 is installed into the inner wall of the shell 1.

[0044] Specifically, the step 12 is a stepped outward protruding structure of the inner wall of the shell 1.

[0045] The outer diameter of the annular seal 2 matches the size of the step 12 and the size of the inner wall of the shell 1, the limiting block 23 protrudes from the annular seal 2, abuts against the inner wall of the shell 1 and is limited in the sliding space 22 by the step 12, and when the atomization assembly is pushed to move by the bottom seal 4, the limiting block 23 fixes the annular seal 2 in the position of the step 12.

[0046] Further, the bottom seal 4 is provided with a limiting groove 41 on the side close to the annular seal 2, and the atomization support 31 is limited in the limiting groove 41.

[0047] It can be understood that the limiting groove 41 provided on the side of the bottom seal 4 close to the annular seal 2 limits the distal end of the atomization support 31 in the limiting groove 41, enhances the stability of the mechanical connection between the atomization support 31 and the bottom seal 4, ensures that the atomization support 31 and the bottom seal 4 always maintain a connection relationship and effectively limit the movement range of the atomization support 31, ensures the stability during the process of pushing the bottom seal 4, and helps the atomization support 31 to bear stress evenly during the process of bearing stress, avoids stress concentration, also provides clear installation positioning for installing the atomization support 31, and improves assembly efficiency.

[0048] The limiting groove 41 is provided in the shape of a ring or a groove 133, and is arranged on the side of the bottom seal 4 close to the annular seal 2.

[0049] One end of the atomization support 31 can be closely matched with the limiting groove 41 to prevent the connection between the atomization support 31 and the bottom seal 4 from being misaligned when being pushed.

[0050] Further, the atomization core assembly 3 further comprises an oil absorbing cotton 32, which is arranged in the atomization support 31 and corresponds to the oil inlet hole 311.

[0051] It can be understood that the oil absorbing cotton 32 can absorb and store a certain amount of tobacco tar through its fiber structure, ensuring that the tobacco tar can be continuously and stably supplied to the atomization area. During the operation of the electronic atomization device 100, the oil absorbing cotton 32 slowly releases the tobacco tar, ensuring the supply of atomized vapor. Corresponding to the oil inlet hole 311, the tobacco tar can quickly and smoothly enter the oil absorbing cotton 32 through the oil inlet hole 311 and be uniformly distributed in the oil absorbing cotton 32.

[0052] The oil absorbing cotton 32 can be fixed in the atomization support 31 by press-fitting or bonding. The oil absorbing cotton 32 and the oil inlet hole 311 are aligned in position to achieve the transmission of tobacco tar.

[0053] Further, the electronic atomization device 100 further comprises a heating assembly 5, which is at least partially arranged in the oil absorbing cotton 32.

[0054] It can be understood that when the heating assembly 5 is partially embedded in the oil absorbing cotton 32, the heating source can directly act on the cotton fibers, making the heating more uniform. The good heat conductivity of the oil absorbing cotton 32 can also uniformly and quickly transfer the heat of the heating assembly 5 to the entire oil absorbing cotton 32, improving the heating efficiency and obtaining more atomized vapor more quickly.

[0055] Further, the side of the shell 1 away from the through hole 11 is connected with a suction nozzle 13, and the suction nozzle 13 is clamped with the shell 1.

[0056] It can be understood that the suction nozzle 13 is directly connected to the shell 1 and designed in a clamping form, ensuring the fixation and stability of the suction nozzle 13 with the device. When not in use, the suction nozzle 13 can be easily removed from the shell 1. When the user inhales, the suction nozzle 13 comfortably fits the lips, providing a smoother and more comfortable inhalation experience for the user.

[0057] The suction nozzle 13 is connected with the shell 1 at the end away from the through hole 11, and the clamping of the suction nozzle 13 with the shell 1 can be achieved by means of a slot, a convex groove structure or a snap ring, etc.

[0058] Further, a groove 133 is arranged on the inner wall of the suction nozzle 13, and a corresponding convex part 17 is arranged on the shell 1. The convex part 17 is inserted into the groove 133 to clamp the suction nozzle 13 with the shell 1. When the user replaces the suction nozzle 13, it can be easily removed from the shell 1.

[0059] Specifically, in order to prevent the suction nozzle 13 from falling off during use, a double clamping structure can also be provided to enhance the firmness, or a sealing ring 7 can be arranged at the clamping part to provide good air tightness. The inner diameter of the suction nozzle 13 matches the inner diameter of the atomized vapor outlet channel of the electronic atomization device 100, ensuring smooth flow of tobacco tar vapor. The part of the suction nozzle 13 entered by the user conforms to the ergonomic design.

[0060] Further, the electronic atomization device 100 further comprises a sealing plug 6, and the shell 1 is provided with an oil injection hole 14 on the side facing the mouthpiece 13.

[0061] Understandably, the oil injection hole 14 is a channel for injecting tobacco tar or other liquid to be atomized into the electronic atomization device 100, and the sealing plug 6 seals the oil injection hole 14, which can effectively prevent air from entering the oil injection hole 14, prevent liquid leakage and keep the interior of the device clean.

[0062] Specifically, the oil injection hole 14 is arranged at the top of the shell 1, away from one end of the through hole 11 and in communication with the oil storage space 21, facilitating users to add tobacco tar to the oil storage space 21.

[0063] The sealing plug 6 is made of rubber or silicone, which has good elasticity and sealing performance. The outer diameter of the sealing plug 6 matches the inner diameter of the oil injection hole 14. When the sealing plug 6 is inserted into the oil injection hole 14, the liquid in the oil storage space 21 will not leak out. The sealing plug 6 also has resilience, which can be easily pulled out and restored to its original state when the user needs to add tobacco tar.

[0064] The shell 1 is further provided with a communication airflow channel between the interior and the mouthpiece 13 to ensure smooth atomization vapor flow, and the airflow channel avoids the oil injection hole 14 to ensure that the airflow channel will not be hindered by the structure of the oil injection hole 14 and the sealing plug 6.

[0065] Specifically, the mouthpiece 13 is provided with a mouthpiece hole 131, and the shell 1 is provided with a gas guide structure 15 on the side facing the mouthpiece 13, which is in communication with the mouthpiece hole 131.

[0066] Understandably, the mouthpiece hole 131 is a channel for the electronic atomization device 100 to directly communicate with the user, and the mouthpiece hole 131 is in communication with the gas guide structure 15 to optimize the airflow path, ensure stable airflow pressure when inhaling, uniform and stable vapor output, provide smooth inhalation, and the hollow inner diameter of the gas guide structure 15 can be adjusted according to different tobacco tar quality to achieve a more ideal inhalation experience.

[0067] The mouthpiece hole 131 is connected with a gas column 132, and the gas column 132 is hollowly arranged, and the gas column 132 penetrates the interior space of the mouthpiece 13 and is in communication with the gas guide structure 15.

[0068] Understandably, the gas column 132 is in direct communication with the gas guide structure 15, which directly guides the tobacco tar vapor and delivers it to the user's mouth through the mouthpiece hole 131, concentrates the vapor and improves the gas guide efficiency.

[0069] Further, the intersection between the air column 132 and the air guide structure 15 is provided with a sealing structure to enhance the sealing of the airflow in the electronic atomizer. The intersection between the air column 132 and the air guide structure 15 is close to the connection position of the oil injection hole 14 blocked by the sealing plug 6. The sealing plug 6 and the sealing structure can be integrally formed to form a sealing plug 6 with a specific shape, which has the functions of blocking the oil injection hole 14 and sealing the air column 132 and the air guide structure 15.

[0070] Further, the air guide structure 15 is hollow, and the end of the atomization support 31 extending into the oil storage space 21 is limited in the air guide structure 15. The air guide structure 15 communicates with the atomization support 31. When the bottom sealing element 4 is pushed towards the side close to the oil storage space 21, the atomization support 31 slides along the air guide structure 15.

[0071] It can be understood that the outer wall of the atomization support 31 is movably connected with the inner wall of the air guide structure 15, and the atomization support 31 can move inside the air guide structure 15. In combination with the pushing of the atomization support 31 by the bottom sealing element 4 before use, the air guide structure 15 provides a moving space for the atomization support 31 to move inside the electronic atomization device 100, prevents the atomization support 31 from damaging the internal structure of the electronic atomization device 100 during movement, and adapts to different use states of the electronic atomization device 100. The air guide structure 15 and the atomization support 31 are in communication to realize a complete conduction path of the tobacco tar from the atomization support 31 to the air guide structure 15 to the suction hole 131 after the tobacco tar is heated in the atomization support 31 to form atomized vapor.

[0072] Specifically, the end of the atomization support 31 extending into the oil storage space 21 is limited in the air guide structure 15, and the inner wall of the air guide structure 15 is smooth. The atomization support 31 is in clearance fit with the air guide structure 15, and the atomization support 31 smoothly slides in the air guide structure 15.

[0073] Further, the air guide structure 15 includes a first air guide structure 151 and a second air guide structure 152. The inner diameter of the second air guide structure 152 is greater than that of the first air guide structure 151. The suction nozzle 13, the first air guide structure 151, and the second air guide structure 152 are in communication in sequence. The end of the atomization support 31 extending into the oil storage space 21 is limited in the second air guide structure 152.

[0074] It can be understood that the inner diameter of the first air guide structure 151 is greater than that of the second air guide structure 152, which limits the excessive movement of the atomization support 31 in the air guide structure 15. The different inner diameters also affect the airflow velocity in the air guide structure 15 during inhalation. The inner diameter of the second air guide structure 152 is smaller, and the flow velocity of the atomized vapor when passing through the second air guide structure 152 is larger, so that the vapor is more concentrated, the intensity of the vapor is enhanced, and more diverse inhalation experiences are brought.

[0075] Specifically, the end of the atomization support 31 towards the side of the mouthpiece 13 can be provided with a sealing ring 7, when the atomization support 31 is pushed to completion by the bottom sealing piece 4, the end of the atomization support 31 extending into the oil storage space 21 is stopped in the second air guide structure 152, and the sealing ring 7 can correspond to the intersection of the first air guide structure 151 and the second air guide structure 152, providing effective gas isolation to prevent atomized vapor from overflowing from the intersection of the first air guide structure 151 and the second air guide structure 152.

[0076] A stop structure can be provided on the atomization support 31 to prevent the atomization support 31 from sliding excessively, and the first air guide structure 151 and the second air guide structure 152 are integrally formed to ensure the continuity of the air guide structure 15 and enhance the compactness and stability of the structure.

[0077] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and any modifications, equivalent replacements and improvements made within the principles of the present application shall be included in the protection scope of the present application.
