Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to an electronic atomizer. Background Technology

[0002] An electronic atomizer includes an atomizing device, which comprises a liquid reservoir and an atomizing component located within the reservoir. The atomizing component atomizes the atomizing matrix within the reservoir into an aerosol. The reservoir is a semi-enclosed chamber. When the atomizing component operates, it generates heat, causing the air within the reservoir to expand. Simultaneously, the volume of the aerosol-state atomizing matrix increases hundreds to thousands of times compared to its liquid state, resulting in high pressure within the reservoir. When the pressure within the reservoir exceeds the tolerance limits of the reservoir structure and its sealing components, some of the liquid atomizing matrix leaks out of the reservoir under the pressure. Utility Model Content

[0003] The main objective of this application is to provide an electronic atomizer that solves the technical problem of leakage caused by high pressure in the liquid storage chamber.

[0004] To achieve the above objectives, this application proposes an electronic atomizer, the electronic atomizer comprising:

[0005] Top shell;

[0006] The mounting base is inserted into the bottom end of the upper shell. The upper shell and the mounting base together form a liquid storage chamber and a pressure relief chamber, which are arranged in a horizontal direction.

[0007] An atomizing component is disposed within the liquid storage chamber;

[0008] A pressure balancing component is slidably disposed within the pressure relief chamber, dividing the pressure relief chamber into a first sub-chamber and a second sub-chamber that are not interconnected. The top end of the first sub-chamber is connected to the top end of the liquid storage chamber.

[0009] A battery holder is disposed below the mounting base. The periphery of the battery holder is sealed to the periphery of the mounting base. An air cavity is formed between the battery holder and the mounting base. The air cavity is connected to the outside atmosphere, the bottom end of the atomizing component, and the second sub-cavity.

[0010] Optionally, the air pressure balancing component slides in the vertical direction, with the first sub-cavity and the second sub-cavity arranged vertically.

[0011] Optionally, the pressure balancing component includes an integrally formed outer cylinder, a middle cylinder, an inner cylinder, an outer ring, and an inner ring. The axial directions of the outer cylinder, the middle cylinder, and the inner cylinder are all parallel to the moving direction of the pressure balancing component. The outer cylinder and the middle cylinder are both open, while the inner cylinder is closed. The middle cylinder is spaced inside the outer cylinder, and the outer ring is sealed between the outer cylinder and the middle cylinder. The inner cylinder is spaced inside the middle cylinder, and the inner ring is sealed between the middle cylinder and the inner cylinder.

[0012] Optionally, the outer cylinder is in the shape of a flared funnel, with the top and bottom peripheral walls of the outer cylinder being interference-fitted to the wall of the pressure relief chamber. The interference amount of the interference connection is greater than or equal to 0.01 and less than or equal to 0.07.

[0013] Optionally, the middle cylinder is completely located inside the outer cylinder, and the outer ring connects the middle part of the outer cylinder and the bottom end of the middle cylinder.

[0014] Optionally, the inner cylinder is completely located inside the outer cylinder, the inner ring connects the top end of the middle cylinder and the top end of the inner cylinder, the axial length of the inner cylinder is greater than the axial length of the middle cylinder, the radius of the inner cylinder is greater than the width of the inner ring, the radius of the inner cylinder is greater than the width of the outer ring, and the bottom end of the inner cylinder is closed.

[0015] Optionally, the annular surface of the outer ring and the annular surface of the inner ring are both perpendicular to the moving direction of the pressure balancing component.

[0016] Optionally, the pressure balancing component is made of polypropylene material, and the Ra of the pressure balancing component is ≤0.01μm.

[0017] Optionally, the mounting base includes a seal and a mounting member. The seal is disposed between the upper shell and the mounting member, and the seal is used to seal the connection between the upper shell and the mounting member. The seal is made of an elastic material, and the mounting member is made of a rigid material.

[0018] Optionally, the bottom surface of the mounting base is recessed towards the second sub-cavity to form a mounting groove, the mounting groove connecting the air chamber and the second sub-cavity, and the electronic atomizer further includes:

[0019] A liquid suction element is disposed in the mounting groove, and the liquid suction element is used to absorb the liquid flowing from the second sub-cavity to the mounting groove.

[0020] Optionally, the electronic atomizer further includes:

[0021] The lower shell is located outside the mounting base. The lower shell has an opening that connects to the outside atmosphere. The top surface of the battery holder has a connecting hole that connects to the air chamber. An air passage is formed between the battery holder and the lower shell. The two ends of the air passage are respectively connected to the connecting hole and the opening.

[0022] In the electronic atomizer of this application, when the air pressure in the liquid storage chamber increases, because the first sub-chamber is connected to the liquid storage chamber, a high pressure is also formed in the first sub-chamber. This high pressure pushes the pressure balancing component to move away from the liquid storage chamber, meaning the volume of the first sub-chamber increases and the volume of the second sub-chamber decreases. Since the second sub-chamber is connected to the outside atmosphere, the high pressure generated by the decrease in the volume of the second sub-chamber can be released to the outside atmosphere in a timely manner, thereby achieving timely depressurization of the liquid storage chamber and preventing leakage. Conversely, when the air pressure in the liquid storage chamber decreases, the pressure balancing component moves in the opposite direction, and the air pressure in the liquid storage chamber can be kept balanced. In this application, the second sub-chamber is connected to the air chamber (the liquid storage chamber is under high pressure, and the gas discharged from the second sub-chamber will not re-enter the liquid storage chamber, but will only be discharged to the outside atmosphere through the air chamber). Compared with the setting where the second sub-chamber is directly connected to the outside atmosphere, this allows for a more compact overall layout of the electronic atomizer, and the second sub-chamber is not directly exposed to the external environment, effectively preventing external dust, moisture, oil, and other impurities from entering the second sub-chamber.

[0039] This application discloses an electronic atomizer, which includes an upper shell, a mounting base, an atomizing component, a pressure balancing component, and a battery holder. The mounting base is inserted into the bottom end of the upper shell, and the upper shell and the mounting base together enclose a liquid storage chamber and a pressure relief chamber, which are arranged horizontally. The atomizing component is disposed in the liquid storage chamber. The pressure balancing component is slidably disposed in the pressure relief chamber, and the pressure balancing component divides the pressure relief chamber into a first sub-chamber and a second sub-chamber that are not interconnected. The top end of the first sub-chamber is connected to the top end of the liquid storage chamber. The battery holder is disposed below the mounting base, and the periphery of the battery holder is sealed to the periphery of the mounting base. An air chamber is formed between the battery holder and the mounting base, and the air chamber is connected to the outside atmosphere, the bottom end of the atomizing component, and the second sub-chamber.

[0040] In the electronic atomizer of this application, when the air pressure in the liquid storage chamber increases, because the first sub-chamber is connected to the liquid storage chamber, a high pressure is also formed in the first sub-chamber. This high pressure pushes the pressure balancing component to move away from the liquid storage chamber, meaning the volume of the first sub-chamber increases and the volume of the second sub-chamber decreases. Since the second sub-chamber is connected to the outside atmosphere, the high pressure generated by the decrease in the volume of the second sub-chamber can be released to the outside atmosphere in a timely manner, thereby achieving timely depressurization of the liquid storage chamber and preventing leakage. Conversely, when the air pressure in the liquid storage chamber decreases, the pressure balancing component moves in the opposite direction, and the air pressure in the liquid storage chamber can be kept balanced. In this application, the second sub-chamber is connected to the air chamber (the liquid storage chamber is under high pressure, and the gas discharged from the second sub-chamber will not re-enter the liquid storage chamber, but will only be discharged to the outside atmosphere through the air chamber). Compared with the setting where the second sub-chamber is directly connected to the outside atmosphere, this allows for a more compact overall layout of the electronic atomizer, and the second sub-chamber is not directly exposed to the external environment, effectively preventing external dust, moisture, oil, and other impurities from entering the second sub-chamber.

[0041] Please combine Figures 1 to 8 The following will mainly describe the specific structure of the electronic atomizer 100.

[0042] The electronic atomizer 100 of this application includes an upper shell 110 and a mounting base 120. The mounting base 120 is inserted into the bottom end of the upper shell 110, and the mounting base 120 and the upper shell 110 can be interference-fitted. The upper shell 110 and the mounting base 120 together enclose a liquid storage chamber 130 and a pressure relief chamber 140, which are arranged horizontally. The top end of the liquid storage chamber 130 is connected to the top end of the pressure relief chamber 140. The liquid storage chamber 130 is used to store the atomizing matrix, and the pressure relief chamber 140 is an empty cavity. The upper shell 110 includes an integrally formed shell body and a partition plate. The partition plate divides the inner cavity of the shell body into two cavities. The inner walls of the two cavities and the top wall of the mounting base 120 respectively form the liquid storage chamber 130 and the pressure relief chamber 140. The top end of the partition plate has a first through hole 143 connecting the two cavities, so that the top end of the liquid storage chamber 130 is connected to the top end of the pressure relief chamber 140. Mounting base 120 includes a seal 121 and a mounting member 122. The seal 121 is disposed between the upper housing 110 and the mounting member 122. The seal 121 is used to seal the connection between the upper housing 110 and the mounting member 122. The seal 121 is made of an elastic material (silicone, plastic and / or rubber), and the mounting member 122 is made of a rigid material (e.g., plastic).

[0043] The electronic atomizer 100 of this application includes an atomizing component 150, which is disposed within a liquid storage chamber 130. The atomizing component 150 is used to atomize the atomizing matrix within the liquid storage chamber 130 into an aerosol. The bottom end of the atomizing component 150 is inserted into a mounting base 120.

[0044] The electronic atomizer 100 of this application includes a lower shell 180, which is connected to the bottom end of an upper shell 110. The lower shell 180 and the upper shell 110 can be connected by interference fit, snap-fit, adhesive bonding, or screw connection. The lower shell 180 is located outside a mounting base 120, and the inner wall of the lower shell 180 can be sealed to the mounting base 120 (e.g., by interference fit). The lower shell 180 has an opening 181 that connects to the outside atmosphere.

[0045] The electronic atomizer 100 of this application includes a pressure balancing component 160, which is slidably disposed within a pressure relief chamber 140. The pressure balancing component 160 divides the pressure relief chamber 140 into a first sub-chamber 141 and a second sub-chamber 142 that are not interconnected. The top end of the first sub-chamber 141 is connected to the top end of a liquid storage chamber 130. The second sub-chamber 142 is connected to the outside atmosphere. The pressure balancing component 160 can slide in the vertical direction, that is, the first sub-chamber 141 and the second sub-chamber 142 are arranged vertically. When the air pressure inside the liquid storage chamber 130 increases, because the first sub-chamber 141 is connected to the liquid storage chamber 130, a high pressure will also be formed inside the first sub-chamber 141. This high pressure will push the pressure balancing component 160 to move away from the liquid storage chamber 130, meaning the volume of the first sub-chamber 141 increases and the volume of the second sub-chamber 142 decreases. Since the second sub-chamber 142 is connected to the outside atmosphere, the high pressure generated by the decrease in the volume of the second sub-chamber 142 can be released to the outside atmosphere in a timely manner, thereby achieving timely pressure relief of the liquid storage chamber 130 and preventing leakage. Conversely, when the air pressure inside the liquid storage chamber 130 decreases, the pressure balancing component 160 moves in the opposite direction, thus maintaining the air pressure balance inside the liquid storage chamber 130.

[0046] The electronic atomizer 100 of this application includes a battery holder 190, which is located below a mounting base 120. The periphery of the battery holder 190 extends toward the mounting base 120 to form a cylindrical structure, and / or the periphery of the mounting base 120 extends toward the battery holder 190 to form a cylindrical structure. The periphery of the battery holder 190 is sealed to the periphery of the mounting base 120. An air chamber 191 is formed between the battery holder 190 and the mounting base 120, that is, there is a gap between the top surface of the battery holder 190 and the bottom surface of the mounting base 120. The battery holder 190 is located inside a lower shell 180. A connecting hole 192 is opened on the top surface of the battery holder 190 to connect to the air chamber 191. An air passage 193 is formed between the battery holder 190 and the lower shell 180. The two ends of the air passage 193 are connected to the connecting hole 192 and the opening 181, respectively. The air chamber 191 is connected to the outside atmosphere through the connecting hole 192, the air passage 193, and the opening 181. The air chamber 191 is also connected to the bottom of the atomizing component 150. When the user inhales, the outside air flows into the atomizing component 150 in sequence through the opening 181, the air passage 193, the connecting hole 192 and the air chamber 191.

[0047] The wall of the second sub-cavity 142 (i.e., the mounting base 120) is provided with a second through hole 144, which connects to the air chamber 191. Compared with the arrangement where the second sub-cavity 142 is directly connected to the outside atmosphere, the above arrangement makes the overall layout of the electronic atomizer 100 more compact, and the second sub-cavity 142 is not directly exposed to the external environment, which can effectively prevent external dust, water vapor, oil and other impurities from entering the second sub-cavity 142.

[0048] The bottom surface of the mounting base 120 (specifically, the mounting element 122) is recessed towards the second sub-cavity 142, forming a mounting groove 123. The mounting groove 123 connects the air chamber 191 and the second sub-cavity 142. The electronic atomizer 100 also includes a liquid suction element 170, which is disposed within the mounting groove 123 and faces the second through hole 144. The liquid suction element 170 is used to absorb the liquid flowing from the second sub-cavity 142 to the mounting groove 123. Therefore, the condensate in the second sub-cavity 142 will not flow into the battery holder 190, preventing damage to the electronic control device on the battery holder 190. The liquid suction element 170 can fill the mounting groove 123. The liquid suction element 170 has an air passage connecting the second sub-cavity 142 and the air chamber 191, thus ensuring airflow while providing good leak-proof performance.

[0049] The air pressure balancing component 160 includes an integrally formed outer cylinder 161, a middle cylinder 163, an inner cylinder 165, an outer ring 162, and an inner ring 164. The axial directions of the outer cylinder 161, the middle cylinder 163, and the inner cylinder 165 are all parallel to the moving direction of the air pressure balancing component 160. The outer cylinder 161 and the middle cylinder 163 are both open, while the inner cylinder 165 is closed. The middle cylinder 163 is spaced inside the outer cylinder 161. The outer ring 162 is sealed between the outer cylinder 161 and the middle cylinder 163. The inner cylinder 165 is spaced inside the middle cylinder 163. The inner ring 164 is sealed between the middle cylinder 163 and the inner cylinder 165.

[0050] In the pressure balancing component 160 of this application, since the outer cylinder 161, middle cylinder 163, inner cylinder 165, outer ring 162, and inner ring 164 are integrally formed, the weak points in the connection caused by separate assembly are avoided, which significantly improves the overall rigidity of the pressure balancing component 160. The force of each component can be evenly transmitted to the overall structure, effectively preventing local deformation and ensuring long-term stability. The cooperation between the multi-level cylindrical structure (outer cylinder 161-middle cylinder 163-inner cylinder 165) and the sealing ring (outer ring 162-inner ring 164) greatly increases the contact area between the pressure balancing component 160 and the gas, which can disperse the force of high-pressure gas to a larger area, avoiding wear and deformation of components caused by local stress concentration, thereby avoiding sealing failure. The middle cylinder 163 and inner cylinder 165 act as airflow guides when the air pressure pushes the balancing component to move, preventing uneven force on the air pressure balancing component 160 caused by airflow turbulence. Simultaneously, the middle cylinder 163 and inner cylinder 165, as motion guide shafts, limit the radial displacement of the air pressure balancing component 160, ensuring its movement trajectory remains consistent with the preset direction, thus avoiding jamming or leakage problems caused by tilting. The ring structures of the outer ring 162 and inner ring 164 are connected to the cylinder wall structures of the outer cylinder 161, middle cylinder 163, and inner cylinder 165 via radial planes. The fit of these radial planes is unaffected by axial movement. During the axial movement of the air pressure balancing component 160, the planar fit between the ring structure and the cylinder wall structure remains constant, preventing the sealing gap from increasing due to axial displacement, thereby avoiding dynamic seal failure under high pressure.

[0051] The outer cylinder 161 is flared outwards at both ends, and its top and bottom peripheral walls are both interference-fitted with the walls of the pressure relief chamber 140. The interference fit is greater than or equal to 0.01 mm and less than or equal to 0.07 mm. Both ends of the outer cylinder 161 are sealed to the walls of the pressure relief chamber 140, preventing gas from entering from the outside of the outer cylinder 161. This eliminates the tilting of the pressure balancer 160 caused by lateral forces, ensuring that the thrust direction is completely consistent with the movement direction. This fundamentally avoids jamming caused by force direction deviation, thus ensuring the sealing performance of the pressure balancer 160 to prevent air pressure leakage, and allowing the pressure balancer 160 to move smoothly under pressure difference. The 0.01–0.07 mm interference fit buffer prevents the seal from opening due to temperature changes, ensuring that the independent sealed spaces of the first sub-chamber 141 and the second sub-chamber 142 are not disturbed by external factors.

[0052] The middle cylinder 163 is completely located inside the outer cylinder 161, meaning the outer cylinder 161 provides full axial coverage of the middle cylinder 163. The outer ring 162 connects the middle of the outer cylinder 161 and the bottom of the middle cylinder 163. This design ensures that the force-bearing (gas-driven) area of ​​the pressure balancing component 160 is between its two ends. Even if the middle cylinder 163 tilts due to gas propulsion, because the outer ring 162 connects to the middle of the outer cylinder 161, the movement of the middle cylinder 163 will only cause adaptive deformation in the middle of the outer cylinder 161, without affecting the sealing connection between the two ends of the outer cylinder 161 and the wall of the pressure relief chamber 140. Thus, the movement of the pressure balancing component 160 driven by gas is relatively stable. At the same time, the concave gap formed between the outer cylinder 161 and the middle cylinder 163 (relative to the direction of gas outflow from the liquid storage chamber 130) can buffer the high-pressure gas.

[0053] The inner cylinder 165 is completely located inside the outer cylinder 161, meaning the outer cylinder 161 also provides full axial coverage of the inner cylinder 165. The inner ring 164 connects the top of the middle cylinder 163 and the top of the inner cylinder 165. The staggered arrangement of the outer ring 162 and the inner ring 164 axially separates the stress points of the outer ring 162 and the inner ring 164, distributing stress across structures at different heights. This avoids localized stress concentration and improves the overall rigidity of the pressure balance component 160. Furthermore, the outer ring 162 and the inner ring 164 together form an axial stepped support structure, further limiting the relative displacement of the components and enhancing the overall structural stability. Similarly, the above design ensures that the pressure balancer 160 is only in the area between its two ends. Even if the inner cylinder 165 tilts due to the gas, the movement of the inner cylinder 165 will not affect the sealing connection between the two ends of the outer cylinder 161 and the wall of the pressure relief chamber 140, since only the outer ring 162 is connected to the middle of the outer cylinder 161.

[0054] The inner cylinder 165 has a longer axial length than the middle cylinder 163, and its radius is greater than the width of the inner ring 164 and the outer ring 162 (meaning the inner cylinder 165 has the largest contact area with the gas). The bottom of the inner cylinder 165 is closed. During the movement of the pressure balancing component 160, the inner cylinder 165, as the core guiding component with the largest contact area with the gas and the main stress point, can reduce the stress load on the outer cylinder 161, allowing the outer cylinder 161 to maintain a sealed connection with the wall of the liquid storage chamber 130 while moving. This ensures that the pressure balancing component 160 always moves along the axis throughout the entire movement process, without the risk of tilting or jamming. The closed bottom of the inner cylinder 165 provides maximum buffer space in its structure, resulting in a better buffering effect for high-pressure gas.

[0055] The annular surfaces of the outer ring 162 and the inner ring 164 are both perpendicular to the moving direction of the pressure balancer 160, that is, the annular surfaces of the outer ring 162 / inner ring 164 are perpendicular to the axial direction of the outer cylinder 161 / middle cylinder 163 / inner cylinder 165. Based on the above configuration, the outer ring 162 forms a lateral tensile constraint on the middle cylinder 163 and the outer cylinder 161, limiting the lateral displacement of the middle cylinder 163 and the outer cylinder 161. Similarly, the inner ring 164 can limit the lateral displacement of the middle cylinder 163 and the inner cylinder 165. As a result, the relative positions of the outer cylinder 161, the middle cylinder 163, and the inner cylinder 165 in the radial direction are fixed, and radial misalignment will not occur. The overall structure of the pressure balancer 160 has good resistance to deformation.

[0056] The pressure balancing component 160 can be made of polypropylene (PP). As a result, the pressure balancing component 160 has moderate elasticity and rigidity, and can produce slight elastic deformation during interference fit, so that the top and bottom peripheral walls of the outer cylinder 161 can fit tightly against the wall of the pressure relief chamber 140.

[0057] The air pressure balancer 160 has a Ra ≤ 0.01 μm. This ultra-precision surface with Ra (arithmetic mean deviation) ≤ 0.01 μm allows the air pressure balancer 160 to ensure its sealing performance through interference fit while reducing sliding resistance with its smooth surface, thus enabling smoother movement of the air pressure balancer 160 under pressure differential. Simultaneously, the surface roughness of Ra ≤ 0.01 μm reduces wear, ensuring the air pressure balancer 160 maintains a stable interference seal over the long term, preventing air pressure leakage due to wear.

[0058] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
