Abstract
Description
Technical Field
[0001] This application relates to the field of atomization technology, and in particular to an atomization device and an electronic atomizer. Background Technology
[0002] In the field of electronic atomizers, rapid and even coil lubrication is crucial to preventing the coil from drying out. Current technologies typically employ a method of compressing the effective liquid storage volume of the oil tank to shorten the lubrication cycle. This increases the internal pressure by squeezing the oil tank, forcing the atomized liquid to quickly penetrate the liquid storage cotton in the coil, thereby accelerating the lubrication process.
[0003] However, the existing technology has flaws in the assembly and connection structure design of the oil tank and atomizing component. Common problems include simultaneous oil tank compression and channel opening, or channel opening lagging behind oil tank compression. When the oil tank is compressed, if the connection channel with the atomizing component is not fully open, the atomizing liquid inside the tank will concentrate at the semi-open channel due to pressure, causing continuous impact on the sealing structure and easily breaching the seal, leading to leakage. Summary of the Invention
[0004] The main objective of this application is to provide an atomizing device and an electronic atomizer to solve the technical problem of oil leakage caused by the incomplete opening of the communication channel between the oil tank and the atomizing component when the oil tank is compressed in the prior art.

[0008] Optionally, a vent is provided at the bottom of the connecting groove. When the push block moves the sealing seat, the space between the seat body and the limiting seat gradually increases, and a negative pressure is formed between the seat body and the limiting seat. The gap between the push block and the connecting groove forms a ventilation channel that communicates with the outside atmosphere and the vent. The outside atmosphere flows into the gradually increasing space between the seat body and the limiting seat through the ventilation channel and the vent.

[0014] Optionally, the sealing seat includes a weak area opposite to the opening, the liquid passage is the weak area, the weak area is more easily punctured by the liquid guide tube than other parts of the sealing seat, and the end of the liquid guide tube away from the atomizing shell is a pointed tip.

[0021] This application discloses an atomizing device, which includes an oil tank, an atomizing assembly, and a limiting member. The oil tank includes a tank body and a sealing seat. An opening is formed on one side of the tank body. The sealing seat seals and connects to the inner wall of the tank body, is opposite to the opening, and closes the opening. The sealing seat is movable relative to the tank body away from the opening. A liquid passage is provided on the sealing seat. The atomizing assembly includes an atomizing shell, a liquid guide tube, and an atomizing core assembly. The atomizing core assembly is at least partially disposed within the atomizing shell. One end of the liquid guide tube is connected to the side of the atomizing shell facing the opening, and the other end of the liquid guide tube is located outside the atomizing shell and facing the opening. The liquid guide tube is inserted into the tank body to open the liquid passage. The atomizing shell is used to push the sealing seat away from the opening to compress the effective liquid storage volume of the tank body. The atomizing shell also serves to connect to the tank body. The pushing force of the liquid guide tube to open the liquid passage is less than the pushing force of the atomizing shell to move the sealing seat. The limiting member connects to the tank body and is used to connect the atomizing assembly to prevent the atomizing assembly from moving further into the tank body.
[0022] In the atomizing device of this application, a gradient force design (the pushing force of the liquid guide tube to open the liquid passage is less than the pushing force of the atomizing shell to move the sealing seat) is used to achieve an orderly action of liquid passage followed by compression. This ensures that the atomizing shell pushes against the sealing seat to compress the chamber only after the connecting channel is fully open, thus completely avoiding the problem of pressure concentration and leakage caused by pressure being applied before the channel is fully open. The gradient force provides clear force feedback, allowing users to judge the assembly progress by feel and avoid incomplete or over-assembly. The limiting component provides mechanical protection, preventing deformation of the sealing seat and damage to the liquid passage caused by over-assembly.
[0023] Please see Figures 1 to 9 The following will mainly describe the specific structure of the atomizing device 10.
[0024] The atomizing device 10 of this application includes an oil tank 100, which includes a tank body 110, with an opening 111 on one side. The tank body 110 is used to store atomizing liquid. The tank body 110 may be generally cylindrical, and the opening 111 may be located at the bottom end of the tank body 110.
[0025] The oil reservoir 100 includes a sealing seat that seals against the inner wall of the reservoir body 110. The sealing seat is opposite to and closes the opening 111. The sealing seat is movable relative to the reservoir body 110 away from the opening 111. When the sealing seat moves away from the opening 111 relative to the reservoir body 110, it moves toward the interior of the reservoir body 110 to compress the effective liquid storage volume of the reservoir body 110. During the movement, the sealing seat maintains a sealed connection with the reservoir body 110, thereby preventing leakage of the atomizing liquid inside the reservoir body 110 during the movement of the sealing seat.
[0026] The sealing seat includes a seat body 120, which seals the inner wall of the chamber 110. The seat body 120 is opposite to the opening 111 and closes the opening 111.
[0027] The seat body 120 includes a sealing portion 121 and a rigid portion 122 connected to each other. The sealing portion 121 is interference-sealed to the inner wall of the chamber 110. The sealing portion 121 focuses on the sealing function and can be made of a highly elastic material (such as silicone, plastic, and / or rubber) to ensure the interference seal effect. The rigid portion 122 is made of a rigid material, such as rigid plastic. The rigid portion 122 enhances the overall structural strength of the seat body 120 and prevents the seat body 120 from deforming due to the thrust of the push rod 130. The sealing portion 121 and the rigid portion 122 can be plate-shaped. The sealing portion 121 is further away from the opening 111 than the rigid portion 122, and one side of the sealing portion 121 is fitted and connected to one side of the rigid portion 122. Therefore, the connection effect between the sealing portion 121 and the rigid portion 122 is better.
[0028] The sealing seat includes a push rod 130, which is located inside the chamber 110. One end of the push rod 130 is fixedly connected to the seat body 120, and the other end faces the opening 111. The push rod 130 is used to push the seat body 120 towards the interior of the chamber 110 under the action of external force. The push rod 130 can be made of a rigid material (such as rigid plastic), and can be fixedly connected to the rigid part 122 of the seat body 120 through an integral molding process. Through the integral molding of the rigid part 122 and the push rod 130, precise and rigid transmission of thrust can be achieved, eliminating the displacement of the sealing surface caused by direct force on the elastic seat body 120, and improving the stability of the moving seal. The push rod 130 and the rigid part 122 can also be fixedly connected by a detachable connection method (such as interference fit or bonding).
[0029] The sealing seat is provided with a liquid passage section 150. The sealing seat includes a weak area opposite to the opening 111, and the liquid passage section 150 can be the weak area. The liquid passage section 150 (weak area) can be an elastic structure on the sealing part 121 with a thickness smaller than the surrounding area, and the liquid passage section 150 (weak area) is more easily punctured than other parts of the sealing part 121. In the initial state, the liquid passage section 150 is kept closed by the tension of the elastic material itself (or the liquid passage section 150 is a closed structure), forming a seal on the opening 111 of the chamber 110. When a foreign object (such as the liquid guide tube 220 of the atomizing component 200) is inserted and pressed into the liquid passage section 150, it can undergo elastic deformation to open the liquid passage channel. After the foreign object is pulled out, it can return to its original position and close again by its own elasticity, thus re-sealing.
[0030] The liquid-passing section 150 and the sealing section 121 can be integrally molded, thereby preventing leakage of atomized liquid from the joint. At the same time, the high elasticity of the sealing section 121 ensures the uniform deformation of the liquid-passing section 150, ensuring that the liquid guide tube 220 opens evenly when pressed and accurately returns to its original position after being pulled out. The rigid section 122 has a first clearance opening 123 corresponding to the liquid-passing section 150. The first clearance opening 123 provides sufficient space for the liquid guide tube 220 to insert and press against the liquid-passing section 150. Furthermore, the sealing section 121 focuses on sealing and liquid-passing functions, while the rigid section 122 uses its rigidity to transmit the thrust of the push rod 130. The first clearance opening 123 clearly defines the functional areas of the two and prevents them from interfering with each other. This ensures both the interference seal between the sealing section 121 and the inner wall of the chamber 110 and the precise application of the push rod 130's thrust to the seat body 120, preventing the sealing surface from shifting due to stress in the liquid-passing section 150 area.
[0031] The atomizing device 10 includes a limiting seat 140, which is located on the side of the body 120 facing the opening 111. The limiting seat 140 is fixedly connected to the chamber 110. A slot 141 is formed in the limiting seat 140 corresponding to the push rod 130, and the push rod 130 is movably inserted into the slot 141. The limiting seat 140 can be made of a rigid material (such as rigid plastic), that is, the limiting seat 140 has a certain structural rigidity. The slot 141 can limit the push rod 130, preventing the push rod 130 from bending or tilting under force, thereby allowing the body 120 to move linearly and preventing the sealing failure (i.e., leakage of the oil tank 100) caused by the tilting of the body 120 and the push rod 130 during the movement. The limiting seat 140 blocks the side of the main body 120 facing the opening 111. The limiting seat 140 has a second clearance opening 147 corresponding to the liquid passage part 150. The function of the second clearance opening 147 is similar to that of the first clearance opening 123, and will not be described again.
[0032] The limiting seat 140 has a recessed connecting groove 143 on the side facing the opening 111, with a slot 141 disposed within the connecting groove 143. One end of the slot 141 is connected to the bottom of the connecting groove 143, and the other end of the slot 141 faces the opening 111. The slot 141 and the connecting groove 143 can be integrally formed. A notch 142 is provided on the side wall of the slot 141, penetrating the end face of the slot 141 near the opening 111. The connecting groove 143 and the slot 141 are connected through the notch 142.
[0033] A vent 144 is provided at the bottom of the connecting groove 143. When an external object (such as the pusher 230 of the atomizing component 200) pushes the sealing seat to move, the space between the seat body 120 (specifically the rigid part 122) and the limiting seat 140 gradually increases, and a negative pressure (the pressure is less than the pressure of the outside atmosphere) is formed between the seat body 120 and the limiting seat 140. The gap between the pusher 230 and the connecting groove 143 forms a ventilation channel that communicates with the outside atmosphere and the vent 144. The outside atmosphere flows into the gradually increasing space between the seat body 120 and the limiting seat 144 through the ventilation channel and the vent 144. The coordinated design of the vent 144 and the vent channel can compensate for the negative pressure formed by the increased space between the seat body 120 and the limiting seat 140 in real time, avoiding the reverse adsorption force generated by the negative pressure from hindering the movement of the seat body 120, making the movement of the sealing seat along the inner wall of the chamber 110 smoother and more uniform; it also avoids the seat body 120 from local deformation due to adsorption force or the gap between it and the inner wall of the chamber 110, ensuring that the seat body 120 maintains a tight interference seal with the inner wall of the chamber 110 throughout the movement, avoiding leakage of atomized liquid at the gap, and preventing the negative pressure fluctuation from causing the liquid passage part 150 to open incompletely or the reset seal to fail.
[0034] A diverter block 146 extends from the opening of the connecting groove 143 toward the interior of the connecting groove 143. The shape of the diverter block 146 is consistent with the shape of the vent 144. The diverter block 146 and the vent 144 are directly opposite each other with a gap. The diverter block 146 is used to prevent the gas in the vent duct from rushing directly to the vent 144. By changing the airflow direction, the diverter block 146 disperses the airflow rushing directly to the vent 144 into a gentle diffused airflow, weakening the instantaneous impact force of the airflow. This makes the outside air flow into the vent duct at a more uniform rate, avoiding sudden changes in airflow that cause air pressure fluctuations between the seat body 120 and the limiting seat 140, and ensuring that the movement speed of the seat body 120 is stable and controllable. The diverter block 146 allows the airflow to diffuse along its surface and then uniformly enter the vent 144. This avoids the lateral force exerted on the seat body 120 by the airflow in one direction, prevents the seat body 120 from shifting or tilting due to the impact of the airflow, ensures that the sealing seat always moves smoothly along the axial direction of the chamber 110, maintains a tight seal between the seat body 120 and the inner wall of the chamber 110, and avoids the risk of leakage caused by shifting.
[0035] The oil tank 100 includes a bottom cover 160, which connects the opening 111 and the limiting seat 140. The bottom cover 160 can enhance the connection between the limiting seat 140 and the tank body 110.
[0036] The atomizing device 10 of this application includes an atomizing assembly 200. The atomizing assembly 200 includes an atomizing shell 210, which is used to push the sealing seat away from the opening 111 to compress the effective liquid storage volume of the chamber 110. The atomizing shell 210 is also used to connect to the chamber 110. A liquid storage chamber is formed inside the atomizing shell 210.
[0037] The atomizing assembly 200 includes a liquid guide tube 220. One end of the liquid guide tube 220 is connected to the side of the atomizing shell 210 facing the opening 111 and communicates with the liquid storage chamber. The other end of the liquid guide tube 220 is located outside the atomizing shell 210 and faces the opening 111. The liquid guide tube 220 is used to insert into the chamber 110 to open the liquid passage 150. The liquid guide tube 220 and the atomizing shell 210 can be integrally formed. The liquid guide tube 220 is used to communicate between the liquid storage chamber and the chamber 110. The end of the liquid guide tube 220 away from the atomizing shell 210 can be a pointed tip, thereby facilitating the liquid guide tube 220 to push open or pierce the liquid passage 150.
[0038] The atomizing assembly 200 includes an atomizing core assembly 240, which is at least partially disposed within the atomizing shell 210. The atomizing core assembly 240 is connected to the liquid storage chamber and is used to atomize the liquid in the liquid storage chamber.
[0039] The pushing force of the liquid guide tube 220 to open the liquid passage 150 is less than the pushing force of the atomizing shell 210 to move the sealing seat. Based on the above settings, the gradient force design achieves an orderly action of liquid passage followed by compression, ensuring that the atomizing shell 210 pushes against the sealing seat compression chamber 110 only after the connecting channel is fully open. This completely avoids the problem of concentrated pressure leakage caused by pressure being applied before the channel is fully open. The gradient force provides obvious force feedback, allowing users to judge the assembly progress by feel and avoid incomplete or over-assembly. The limiting component provides mechanical protection, preventing deformation of the sealing seat and damage to the liquid passage 150 caused by over-assembly.
[0040] A push block 230 extends from the side of the atomizing shell 210 facing the opening 111, corresponding to the push rod 130. The push block 230 is used to push the push rod 130 away from the opening 111, and the push rod 130 can drive the base body 120 to move.
[0041] The atomizing component 200 (specifically, the atomizing shell 210) includes a connecting side 211 facing the opening 111. One end of the atomizing core component 240 extends out of the connecting side 211. The pusher block 230 is an arc-shaped plate that semi-encloses the atomizing core component 240. One side of the pusher block 230 is connected to the connecting side 211. One end of the liquid guide tube 220 is connected to the connecting side 211 and is located on one side of the pusher block 230. The pusher block 230 adopts an arc-shaped plate design that semi-encloses the atomizing core component 240. Combined with its fixing structure with the connecting side 211 of the atomizing shell 210, it can form a lateral limiting and support for the atomizing core component 240. It efficiently integrates the functions of liquid guiding, pushing, and support within the limited space of the connecting side 211, making the overall volume of the atomizing component 200 smaller, while avoiding interference between components and improving assembly compatibility.
[0042] The notch 142 on the slot 141 allows the push block 230 to pass through, enabling it to insert into the connecting groove 143 and the slot 141. The portion of the push block 230 opposite to the slot 141 is used to move the push rod 130. The connecting groove 143, the slot 141, and the notch 142 provide guidance and constraint for the push block 230, ensuring its precise insertion into the connecting groove 143 and the slot 141. This prevents any misalignment between the push block 230 and the push rod 130, achieving precise force transmission. The connection groove 143 and the slot 141 have a stronger overall structure and can withstand the impact force during the insertion and pushing of the push block 230 compared to the slot 141 itself, preventing cracking and deformation of the slot 141 due to localized stress concentration. The notch 142 satisfies the need for the push block 230 to pass through without excessively weakening the sidewall strength of the slot 141, balancing structural practicality and durability, and extending the service life of the limit seat 140. The matching design of the notch 142 and the pusher block 230 allows the pusher block 230 to semi-enclose the arc structure of the atomizing core assembly 240 and perfectly match the slot 141 and the connecting groove 143, avoiding interference between the pusher block 230 and the side wall of the slot 141, while reserving sufficient space for the liquid guide tube 220 to be arranged on both sides, thus improving the structural flexibility.
[0043] The shape of the connecting groove 143 can be adapted to the shape of the push block 230. Therefore, the connecting groove 143 and the push block 230 can form a full-circumferential conformal guide, guiding the push block 230 to insert precisely along a preset trajectory, preventing the push block 230 from shifting or tilting, ensuring precise alignment between the push block 230 and the push rod 130, and between the liquid guide cylinder 220 and multiple weak points, guaranteeing that the timing of the coordinated actions of each component is not deviated. The shape adaptation significantly reduces the fit gap between the two, avoiding airflow turbulence caused by excessively large / small local gaps, ensuring that outside air flows in smoothly through the vent, precisely maintaining the air pressure balance on both sides of the seat body 120, and ensuring smooth movement of the sealing seat.
[0044] The push block 230 and the connecting groove 143 can be engaged. The groove wall of the connecting groove 143 has a latch 145, and the push block 230 has a corresponding latch block for engaging with the latch 145. The precise engagement of the latch block and the latch 145 achieves rigid fixation between the atomizing component 200 and the oil tank 100. The anti-dislodgement force of the latch structure prevents accidental contact that could cause the atomizing component 200 to fall off, improving safety. The clear tactile feedback of the latch at the moment of engagement, combined with the gradient force feedback, provides a dual assembly indication, allowing the user to accurately determine whether the atomizing component 200 is properly assembled. There can be at least two latches 145 and latch blocks, with each latch 145 and each latch block corresponding to the other.
[0045] The pusher block 230 has a clearance area corresponding to the diverter block 146. The clearance area of the pusher block 230 is adapted to the diverter block 146, which can reserve sufficient space for the diverter block 146 during the process of inserting the pusher block 230 into the connecting groove 143 and the slot 141, avoiding collisions and jamming between the pusher block 230 and the diverter block 146, and ensuring that the pusher block 230 is smoothly and accurately connected to the pusher rod 130. The clearance area can adopt an adaptation design that fits the shape of the diverter block 146. In this way, the volume of the pusher block 230 or the connecting groove 143 can be increased to achieve a compatible layout between components. The pusher block 230, the diverter block 146, the liquid guide tube 220 and other components can be accommodated in a limited space, which further enhances the compactness of the overall structure of the atomizing device 10. The adaptation relationship between the avoidance zone and the diversion block 146 can also form an auxiliary positioning function, guiding the push block 230 to insert along the preset trajectory, further ensuring the precise alignment of the push block 230 with the connecting groove 143 and the push rod 130.
[0046] The number of push blocks 230 is at least one. The number of connecting grooves 143, slots 141, and push rods 130 is twice the number of push blocks 230. Two push rods 130 are arranged in a group, corresponding one-to-one with one push block 230. The two push rods 130 in a group are opposite to the two extended ends of the push block 230. At least two slots 141 are inserted into at least two push rods 130, and at least two slots 141 are connected to at least two connecting grooves 143. The above design can synchronously and evenly transmit the thrust of the push block 230 to both sides of the seat body 120, avoiding the twisting and tilting of the seat body 120 caused by a single push rod 130 or force offset, and ensuring that the sealing seat moves linearly along the axial direction of the chamber body 110. The double number of connecting grooves 143, slots 141, and push rods 130 form a symmetrical assembly structure, providing bidirectional constraint and support for the push block 230, and greatly improving the connection stability between the push block 230 and the limiting component and sealing seat. The doubled number of components creates redundant support. Even if a single push rod 130 or slot 141 experiences slight wear, the other set can still ensure thrust transmission and structural fixation, preventing direct device failure. At the same time, the symmetrical structure can adapt to greater thrust requirements and is compatible with high-pressure compression scenarios such as large-capacity oil tanks and high-viscosity atomizing liquids, thus broadening the device's applicability.
[0047] The number of push blocks 230, liquid guide tubes 220, and connecting grooves 143 can be two. Two push blocks 230 are located on opposite sides of the atomizing core assembly 240, one liquid guide tube 220 is located between one end of the two push blocks 230, and the other liquid guide tube 220 is located between the other ends of the two push blocks 230. The two push blocks 230 are symmetrically arranged on both sides of the atomizing core assembly 240. Combined with the liquid guide tubes 220 located at both ends, this achieves balanced liquid supply to both sides of the atomizing core assembly 240. Simultaneously, the symmetrical thrust transmission makes the sealing seat more stable. The liquid guide tubes 220 are located in the gap between the two ends of the two push blocks 230, fully utilizing the redundant space between the push blocks 230. This achieves a double push block 230 and double liquid guide tube 220 structure while maintaining the overall miniaturization of the device. The dual liquid guide cylinders 220 synchronously connect with the weak area of the base body 120 to supply liquid, forming a redundant liquid supply channel to avoid liquid supply interruption; at the same time, the dual push blocks 230 work together to distribute the pushing load and improve the device's fault resistance.
[0048] The atomizing device 10 of this application includes a limiting member connected to the chamber 110. The limiting member is used to connect the atomizing component 200 to prevent the atomizing component 200 from moving further into the chamber 110. The limiting member can be the limiting seat 140 mentioned above. The limiting seat 140 conveniently integrates structures such as the connecting groove 143, slot 141, bayonet 145, flow divider 146, and air vent 144, realizing a multi-functional integrated design of limiting, guiding, fixing, and air pressure balancing, making the connection between the oil chamber 100, the limiting seat 140, and the atomizing component 200 more compact and improving the overall structural synergy. The limiting member (limiting seat 140) evenly distributes the impact force and limiting stress transmitted by the atomizing component 200 to the corresponding area of the chamber 110 through a connection method that fits the chamber 110 in a full circumferential direction, avoiding deformation and cracking at the opening 111 of the chamber 110 due to local stress concentration, and taking into account both the reliability of limiting and the structural integrity of the chamber 110.
[0049] Atomizing device 10 includes a detached state; please refer to [link / reference]. Figures 4 to 6 In the detached state, the oil tank 100 and the atomizing assembly 200 are detached, the liquid passage 150 is closed, and the effective liquid storage volume of the chamber 110 is the first liquid storage volume. The atomizing device 10 includes a liquid-passing state; in the liquid-passing state, the liquid guide tube 220 is inserted into the opening 111 and the liquid passage 150 is opened. The chamber 110 is connected to the atomizing core assembly 240 through the liquid guide tube 220, and the effective liquid storage volume of the chamber 110 is the second liquid storage volume, which is smaller than the first liquid storage volume. Please refer to [link / reference]. Figures 1 to 3 The atomizing device 10 includes a push-fit state; in the push-fit state, the atomizing shell 210 is inserted into the opening 111 and pushes the sealing seat away from the opening 111. The chamber 110 is connected to the atomizing core assembly 240 through the liquid guide tube 220. The effective liquid storage volume of the chamber 110 is the third liquid storage volume, which is smaller than the second liquid storage volume.
[0050] The effective liquid storage volume is reduced in three stages. In the disassembly stage, the first liquid storage volume maximizes the liquid storage capacity. In the liquid-passing stage, the second liquid storage volume initially adapts to the liquid guiding and connection requirements. In the push-loading stage, the third liquid storage volume achieves deep compression of the chamber at 110°, gradually pushing the atomized liquid to the liquid-passing section at 150°, reducing residue and further improving the liquid storage utilization rate. At the same time, it avoids liquid shock and sudden increase in liquid supply caused by excessive single compression, ensuring a uniform and stable supply of atomized liquid. The three stages clearly distinguish the action logic of "disassembly and closure - liquid-passing and connection - deep compression". In the disassembly stage, the liquid-passing section at 150° is closed to prevent leakage of atomized liquid when not assembled. In the liquid-passing stage, the connection channel is established first and then the volume is initially controlled. In the push-loading stage, the channel is stably open during deep compression. From the state level, it prevents concentrated leakage caused by compression before liquid-passing, forming a closed loop to prevent leakage throughout the entire process. The three states correspond to clear structural positions and force feedback. Users can accurately judge the state of the device by measuring the assembly depth and force changes, avoiding incomplete assembly (remaining in the liquid flow state without entering the push-fit state) or over-assembly. At the same time, the structural constraints in each state (such as the liquid guide cylinder 220 limit in the liquid flow state and the fixed limit component in the push-fit state) can ensure the stability of the state and improve the consistency of batch assembly and the safety of use.
