Description

Electronic atomization device Technical Field

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

[0002] Electronic atomizers use electricity to heat a liquid, bringing it to its boiling point and transforming it into vapor. Currently widely used in the e-cigarette industry, these devices can be broadly categorized by their liquid storage structure: liquid storage tanks and porous storage tanks. Liquid storage tanks store atomized liquid in a fluidic reservoir, where the liquid remains in a fluid state, making it easy for users to monitor the remaining amount. However, due to pressure fluctuations caused by the liquid's own weight and ambient temperature, the atomized liquid in the reservoir can easily leak. Another type uses a porous storage structure, where atomized liquid is replenished by drawing atomized liquid from a porous reservoir within the fluidic reservoir. The principle is that the large gaps between the porous reservoirs create tension between the liquid and the liquid, preventing it from leaking out of the fluidic reservoir due to its own weight. Since the liquid level cannot be monitored, users cannot tell how much liquid is remaining, leading to a lack of atomized liquid and resulting in a fuming core. Therefore, these atomizers are often designed to drain the battery before the liquid level, making them common in disposable atomizers. While this solves the leakage problem, the battery cannot be recharged or reused, which poses a significant environmental risk. Therefore, an atomizer structure is needed that can completely solve the problem of liquid leakage and allow users to easily observe the remaining oil amount. Summary of the Invention

Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0050] Figures 1 to 13 show an electronic atomization device in some preferred embodiments of the present invention, including a shell 10, an atomization component 20 arranged in the shell 10, a non-flowing liquid tank 52 and the atomization component 20, the flowing liquid tank 51 and the non-flowing liquid tank 52 store atomized liquid and at least one connecting channel 50 is provided between the two, the atomization component 20 includes an atomization core 22 and a liquid inlet 211 opened toward the atomization core 22; the non-flowing liquid tank 52 is filled with a porous liquid storage 30 with a hollow structure, the atomization component 20 is arranged in the hollow structure of the porous liquid storage 30, and the liquid inlet 211 is connected to the porous liquid storage 30.

[0051] When the air outlet end of the electronic atomization device is facing upward, the connecting channel 50 is arranged in the middle and / or upper part of the flowing liquid tank 51; that is, when the electronic atomization device is placed upright, the flowing liquid tank 51 is divided into the upper part, the middle part and the lower part. The connecting channel 50 can be provided in the middle part of the flowing liquid tank 51, or the connecting channel 50 can be provided in the upper part of the flowing liquid tank 51, or the connecting channel 50 can be provided in the middle and upper parts of the flowing liquid tank 51; when the air outlet end of the electronic atomization device is placed horizontally or tilted, the liquid in the flowing liquid tank 51 at least immerses one of the connecting channels 50 to replenish the non-flowing liquid tank 52.

[0052] In the electronic atomization device of the present invention, due to the presence of the non-flowing liquid tank 52, the liquid in the non-flowing liquid tank 52 is absorbed by the porous liquid storage 30, and the atomization core 22 is covered by the porous liquid storage 30. Therefore, the atomization core 22 is subjected to less pressure from the deadweight of the atomized liquid, which is not easy to cause leakage of the atomized liquid. At the same time, the flow liquid tank 51 can observe the amount of atomized liquid inside by setting a visible shell. When the amount of liquid in the flow liquid tank is sufficient, the liquid in the flow liquid tank 51 is immersed in the connecting channel 50; after a period of use, the amount of liquid in the flow liquid tank 51 decreases, and the connecting channel 50 is exposed to the liquid-free section of the flow liquid tank. Since users generally tilt the electronic atomization device at a certain angle when using it, the liquid in the flow liquid tank 51 can be immersed in the connecting channel 50 again and enter the non-flowing liquid tank 52 and be absorbed by the porous liquid storage 30. The liquid that the porous liquid storage 30 itself can store can also be used by the electronic atomization device for a period of time. When the electronic atomization device is tilted or placed horizontally, the liquid in the flow liquid tank 51 can also be replenished into the porous liquid storage. This design is different from the original electronic atomization device in which the atomization core 22 is at the lowest position and in direct contact with the flowing liquid tank 51, so that the liquid in the flowing liquid tank 51 will not leak due to the influence of its own gravity, and it is also convenient to observe the remaining liquid amount and ensure the normal supply of atomized liquid.

[0053] In the present invention, the porous liquid reservoir 30 can be a porous structure capable of absorbing and storing atomized liquid, such as liquid storage cotton, plastic fiber liquid storage, porous ceramic liquid storage, and porous fiber liquid storage, without specific limitation. According to experimental data, 1 ml of atomized liquid can be used by the user for approximately 80-151 puffs. Therefore, it is more appropriate to design the porous liquid reservoir 30 to have a volume between 0.5-5 ml. A 0.5 ml volume of the porous liquid reservoir 30 can store liquid for at least 30-70 puffs. In other words, when there is a large amount of atomized liquid in the flowing liquid chamber 51, the atomized liquid is in contact with the porous liquid reservoir 30, and there is no need to worry about the atomizer core 22 being stuck due to insufficient atomized liquid. Since the liquid inlet 211 of the atomizer core 22 is not in direct contact with the flowing liquid chamber 51, there is no need to worry about liquid leakage. Even if the residual heat of the atomizer core 22 during use heats the porous liquid reservoir 30, reducing the high temperature tension of the atomized liquid and accelerating the flow, there will be no problem of liquid leakage. When the liquid level in the flowing liquid tank 51 is low, the electronic atomizer device can be placed horizontally, or the user can stand upside down to observe the remaining liquid level, so that the liquid in the flowing liquid tank 51 can be immersed in the connecting channel 50 and then enter the non-flowing liquid tank 52, thereby replenishing the porous liquid storage 30. Therefore, the atomizer core 22 will not have the problem of core sticking.

[0054] In a specific embodiment, the electronic atomization device further includes an oil separator 40; the atomization assembly 20 includes a mounting bracket 21 and an atomization core 22 arranged in the mounting bracket 21; a suction nozzle 11 is provided at the top of the shell 10, the upper end of the mounting bracket 21 is abutted against the lower end of the suction nozzle 11, the atomization core 22 is arranged close to the suction nozzle 11, and the interior of the mounting bracket 21 is connected to the suction nozzle 11, so that the atomized vapor atomized by the atomization core 22 can be inhaled by the user through the suction nozzle 11; an insertion hole is provided on the porous liquid storage 30, and the mounting bracket 21 is inserted outside the insertion hole, so that the porous liquid storage 30 is correspondingly sleeved outside the atomization core 22. The corresponding sleeve here means that the porous liquid storage 30 corresponds to the atomization core 22 The liquid inlet position is set so that the atomized liquid in the porous liquid storage 30 can be supplied to the atomizer core 22; a liquid inlet 211 is provided on the mounting bracket 21 to supply liquid to the atomizer core 22; a mounting hole can be provided on the oil separator 40, and the mounting bracket 21 is passed through the mounting hole. The oil separator 40 is arranged between the flowing liquid tank 51 and the non-flowing liquid tank 52. In other words, the oil separator 40 separates the flowing liquid tank 51 from the non-flowing liquid tank 52, but a connecting channel 50 is provided between the flowing liquid tank 51 and the non-flowing liquid tank 52, so that the atomized liquid in the flowing liquid tank 51 can be supplied to the porous liquid storage 30, and the stored liquid in the porous liquid storage 30 can be supplied to the atomizer core 22.

[0055] As shown in Figure 3, the atomizer core 22 includes a liquid guide 221 and a heating element 222 embedded in or attached to the liquid guide 221. The liquid guide 221 refers to a porous material that can supply liquid through. It can be a porous ceramic liquid guide, or it can be a liquid guide cloth or liquid guide cotton with a certain degree of elasticity. The heating element 222 is used to atomize the liquid on the liquid guide 221, causing the atomized liquid to be atomized to form atomized vapor. The atomizer core 22 is installed in the mounting bracket 21. The mounting bracket 21 is provided with a liquid inlet 211 to connect the porous liquid storage 30 with the liquid guide 221. In the present invention, the atomizer core 22 is arranged near the upper suction nozzle 11. Since the liquid inlet 211 on the atomizer core 22 serves as the only channel connecting the porous liquid storage 30 and the internal liquid guide 221, the atomizer core 22 can greatly reduce the pressure generated by the dead weight of the liquid, and can effectively prevent the leakage of the atomized liquid. Because the suction nozzle 11 is generally placed upward or horizontally when the electronic atomizer device is not in use, it is almost impossible to place the suction nozzle 11 downward. The atomizer core 22 does not directly contact the flowing liquid tank 51, which can prevent leakage caused by the dead weight of the liquid in the flowing liquid tank 51.

[0056] A porous liquid storage 30 of a certain volume is provided on the outside of the atomizer core 22. The function of the porous liquid storage 30 is to buffer the liquid pressure. Because the electronic atomizer device may have the nozzle 11 placed downward, the larger micropores in the porous liquid storage 30 make it less likely for the liquid to leak due to its own tension. Another thing is that when the atomized liquid in the flowing liquid tank 51 is less, the atomizer core 22 is not in contact with the flowing liquid tank 51, while a certain amount of atomized liquid can be stored in the porous liquid storage 30, and the atomized liquid can be used by the atomizer core 22 for a period of time; according to the user's usage and battery power, it is set that when the amount of liquid is relatively small, the communication channel 50 is exposed from the atomized liquid, and the liquid in the flowing liquid tank 51 cannot contact the porous liquid storage 30. When the atomizer is charged or not in use, it can only be placed horizontally. At this time, the liquid in the flowing liquid tank 51 immerses the communication channel 50, and the atomized liquid in the flowing liquid tank 51 is replenished to the non-flowing liquid tank 52, thereby replenishing the liquid in the porous liquid storage 30. When the user uses it again, the atomized liquid in the porous liquid storage 30 can be used for a period of time.

[0057] Under normal usage of the electronic atomizer device, the mouthpiece 11 part needs to be held by the human body, and the electronic atomizer device will present a certain tilt angle with the human body. When the atomized liquid in the flowing liquid tank 51 is sufficient, the liquid in the flowing liquid tank 51 is immersed in the connecting channel 50, and the liquid in the flowing liquid tank 51 is in contact with the non-flowing liquid tank 52. The capillary structure of the porous liquid storage 30 can absorb the liquid in the flowing liquid tank 51. When the atomized liquid is less, the atomized liquid has been almost consumed. According to the statistical usage habits of users, the average user uses it continuously for 20-30 mouthfuls. During the rest time or when the battery 80 is not in use, the electronic atomizer device is designed to be placed only horizontally. The tilted or horizontal placement can allow the liquid in the flowing liquid tank 51 to immerse the connecting channel 50, so that the liquid in the flowing liquid tank 51 is in full contact with the non-flowing liquid tank 52, so that the porous liquid storage 30 can absorb the liquid in the flowing liquid tank 51.

[0058] In a specific embodiment, as shown in Figures 2 to 5, the oil separator 40 is provided outside the mounting bracket 21. The top wall of the oil separator 40, the outer wall of the mounting bracket 21, and the inner wall of the housing 10 define a non-flowing liquid tank 52. The porous liquid storage 30 is filled in the non-flowing liquid tank 52. The flowing liquid tank 51 is provided below the porous liquid storage 30. It can be understood that the non-flowing liquid tank 52 and the flowing liquid tank 51 are separated by the oil separator 40. There is a connecting channel 50 between the two to allow liquid to pass through. The porous liquid storage 30 and the atomizing core 22 are designed to be biased upward so that the atomizing core 22 is less subject to the pressure of the liquid's own weight, which is not likely to cause leakage of the atomized liquid. At the same time, the flowing liquid tank 51 below can be provided with a visual material through the corresponding housing 10, which facilitates observation of the liquid volume in the flowing liquid tank 51.

[0059] In one specific embodiment, as shown in Figures 2-5 , the oil separator 40 is provided with at least one oil guide hole, which forms a communication channel 50. This oil guide hole can connect a flowing liquid reservoir 51 with a non-flowing liquid reservoir 52. The oil guide hole can be located in the center or at the edge of the oil separator 40, and the cross-section of the oil guide hole can be a straight hole, a curved hole, or a combination thereof.

[0060] In another specific embodiment, the oil separator 40 is provided with a through groove along the circumference, and the through groove cooperates with the shell 10 to form a connecting channel 50, as shown in Figures 1 and 2; when the amount of liquid in the flowing liquid tank 51 is small, and the porous liquid storage 30 needs to be supplemented with atomized liquid, the connecting channel 50 is arranged at the edge so that the atomized liquid in the flowing liquid tank 51 can be supplied to the porous liquid storage 30 through the connecting channel 50 by tilting the electronic atomization device at a small angle.

[0061] In a specific embodiment, as shown in Figures 1 to 5, the electronic atomization device also includes a seal 60 disposed below the atomization assembly 20. The inner wall of the housing 10, the bottom wall of the oil separator 40, the mounting bracket 21, and the seal 60 define a flowing liquid tank 51. The seal 60 is used to seal the mounting bracket 21 and the flowing liquid tank 51, and to seal the flowing liquid tank 51 and the housing 10 to prevent leakage. In other words, it can be understood that the flowing liquid tank 51 is disposed below the porous liquid storage 30 and the atomization core 22. The non-flowing liquid tank 52 and the flowing liquid tank 51 are separated by the oil separator 40, and there is a connecting channel 50 between the two to allow liquid to pass through. The design of the porous liquid storage 30 and the atomization core 22 not being in direct contact with the flowing liquid tank 51 means that the atomization core 22 is less subject to the pressure of the liquid's own weight, which is not likely to cause leakage of the atomized liquid. At the same time, the flowing liquid tank 51 below makes it easy to observe the amount of liquid.

[0062] In a specific embodiment, as shown in Figures 6 to 9, the shell 10 is provided with a circle of mounting walls 12 extending from top to bottom, and a gap is left between the mounting wall 12 and the inner wall of the shell 10, which forms a part of the flowing liquid tank 51; the porous liquid storage 30 and the oil separator 40 are both arranged between the mounting wall 12 and the mounting bracket 21, and the oil separator 40 is arranged at the bottom of the porous liquid storage 30. The inner wall of the mounting wall 12, the top wall of the shell 10, the mounting bracket 21 and the top wall of the oil separator 40 define the non-flowing liquid tank 52. The flowing liquid tank 51 is arranged below and to the side of the non-flowing liquid tank 52. The flowing liquid tank 51 has a similar concave structure. The non-flowing liquid tank 52 is arranged in a concave position. Part of the flowing liquid tank 51 is located below the non-flowing liquid tank 52, and part of the flowing liquid tank 51 surrounds the outside of the non-flowing liquid tank 52. It can be understood that this design allows the electronic atomization device of the same specification to have a larger area occupied by the flowing liquid tank 51, and the flowing liquid tank 51 can store more atomized liquid; the electronic atomization device can be made into a finished product with a larger diameter but not very high height. The advantage is that when the diameter of the flowing liquid tank 51 is large and the height is not high, when the atomized liquid is slightly tilted, the atomized liquid and the non-flowing liquid tank 52 can be in good contact, thereby supplying liquid to the porous liquid storage 30.

[0063] In a specific embodiment, the electronic atomization device also includes a seal 60 arranged below the atomization assembly 20. The side wall of the shell 10, the outer wall of the mounting wall 12, the bottom wall of the oil separator 40, the outer wall of the mounting bracket 21 and the seal 60 define a flowing liquid tank 51, as shown in Figures 6-9, so that the volume of the formed flowing liquid tank 51 is larger and can store more atomized liquid.

[0064] In a specific embodiment, as shown in Figures 6 to 9, the flowing liquid tank 51 is wrapped around the bottom and the non-flowing liquid tank. At this time, the connecting channel 50 connecting the flowing liquid tank 51 and the non-flowing liquid tank 52 can be arranged below, around, or both of the non-flowing liquid tank 52; at this time, an oil guide hole can be opened on the installation wall 12 to form the connecting channel 50, and the oil guide hole can be arranged along the circumference of the installation wall 12, and the oil guide hole connects the flowing liquid tank 51 and the non-flowing liquid tank 52; or an oil guide hole is opened on the oil separator 40 to form the connecting channel 50, and at this time the oil guide hole can be arranged in the middle or at the edge of the oil separator 40, and the oil guide hole connects the flowing liquid tank 51 and the non-flowing liquid tank 52; or oil guide holes are provided on both the installation wall 12 and the oil separator 40, and the oil guide holes form the connecting channel 50. This design allows the atomized liquid in the flowing liquid tank 51 to be replenished to the non-flowing liquid tank 52 more quickly, which is beneficial to improving the user experience. The cross section of the oil guide hole can be a straight hole, a curved hole or a combination thereof.

[0065] In a specific embodiment, as shown in Figures 1 and 6 to 9, the oil separator 40 is preferably provided with a through groove along the circumference, and the through groove cooperates with the mounting wall 12 to form an oil guide hole, and the oil guide hole forms a connecting channel 50. When the amount of liquid in the flowing liquid tank 51 is small and the porous liquid storage 30 needs to be supplemented with atomized liquid, the oil guide hole is arranged at the edge so that the atomized liquid in the flowing liquid tank 51 can be supplied to the porous liquid storage 30 through the oil guide hole as long as the electronic atomization device is tilted at a small angle.

[0066] In a specific embodiment, as shown in Figures 10-13, the flowing liquid tank 51 and the non-flowing liquid tank 52 are arranged side by side, and the communication channel 50 between the two is located at the upper end of the flowing liquid tank 51. The side-by-side arrangement here can be parallel or offset, and the communication channel 50 between the two is located at the upper end of the flowing liquid tank 51. It can be understood that the electronic atomization device of the present invention is provided with two liquid storage tanks connected by channels, one is a flowing liquid tank 51 storing atomized liquid, in which the atomized liquid will flow under gravity, and the other is a non-flowing liquid tank 52 filled with a porous liquid storage 30. The atomized liquid in the non-flowing liquid tank 52 is absorbed by the porous liquid storage 30, and the atomization component 20 and the porous liquid storage 30 are connected through the connecting channel 50 to supply liquid to the atomization core 22. Therefore, the non-flowing liquid tank 52 and the atomization core 22 are subjected to less pressure from the self-weight of the atomized liquid, and are not prone to leakage of the atomized liquid. At the same time, when placed horizontally or tilted, the atomized liquid in the flowing liquid tank 51 can immerse at least one of the connecting channels 50, so that the atomized liquid in the flowing liquid tank 51 can be replenished into the porous liquid storage of the non-flowing liquid tank 52.

[0067] In a specific embodiment, as shown in Figures 10 to 13, the electronic atomization device includes an oil separator 40, a seal 60 arranged at the lower part of the shell 10 and sealed with the shell 10, and a base 120 is also provided at the bottom of the shell 10; the oil separator 40 can be a plate-like structure, and the oil separator 40 is longitudinally arranged between the shell 10 and the seal 60 to divide the shell 10 into two parts, one part is a flowing liquid tank 51, and the other part is a non-flowing liquid tank 52; the seal 60 can be a sealing bottom plug that cooperates with the inner wall surface of the bottom of the shell 10 to prevent leakage of the atomized liquid.

[0068] In a specific embodiment, as shown in Figures 10 to 13, the atomizer assembly 20 includes a mounting bracket 21 and an atomizer core 22 disposed in the mounting bracket 21; a nozzle 11 is disposed at the top of the housing 10, the upper end of the mounting bracket 21 abuts against the lower end of the nozzle 11, the atomizer core 22 is disposed close to the nozzle 11, and the interior of the mounting bracket 21 is communicated with the nozzle 11, so that the atomized steam atomized by the atomizer core 22 can be inhaled by the user through the nozzle 11; a liquid inlet 211 is provided on the mounting bracket 21 to supply liquid to the atomizer core 22; A through hole is formed in the liquid reservoir 30, and the mounting bracket 21 is inserted outside the through hole, so that the porous liquid reservoir 30 is correspondingly sleeved outside the atomizer core 22. The corresponding sleeve here means that the porous liquid reservoir 30 is arranged corresponding to the liquid inlet 211 of the atomizer core 22, so that the atomized liquid in the porous liquid reservoir 30 can be supplied to the atomizer core 22; the left side of the oil separator 40, the housing 10, the mounting bracket 21, and the sealing member 60 define a non-flowing liquid tank 52; the right side of the oil separator 40, the housing 10 and the sealing member 60 define a flowing liquid tank 51.

[0069] In one embodiment, at least one oil guide hole is defined at the upper end of the oil separator 40. The oil guide hole forms a communication channel 50, and the oil guide hole can connect the flowing liquid reservoir 51 and the non-flowing liquid reservoir 52. The cross-section of the oil guide hole can be a straight hole, a curved hole, or a combination thereof.

[0070] In one embodiment, a gap is left between the oil separator 40 and the housing 10, forming a communication channel 50. When the amount of liquid in the liquid reservoir 51 is low and the porous liquid reservoir 30 needs to be replenished with atomized liquid, the communication channel 50 is located at the upper end so that the atomized liquid in the liquid reservoir 51 can be supplied to the porous liquid reservoir 30 through the communication channel 50 by simply tilting or horizontally adjusting the electronic atomization device.

[0071] In a specific embodiment, as shown in Figures 10 to 13, a plug-in portion 42 is extended from the bottom of the oil separator 40, and a plug-in groove 61 matching the plug-in portion 42 is provided on the sealing member 60. The plug-in portion 42 is sealed and plugged into the plug-in groove 61, thereby separating the flowing liquid tank 51 from the non-flowing liquid tank 52 and preventing leakage at the connection.

[0072] In a specific embodiment, as shown in Figure 1, the electronic atomization device also includes a shell 70 that cooperates with the shell 10. The shell 10 and the shell 70 cooperate to form the outer wall of the electronic atomization device. The seal 60 divides the electronic atomization device into two parts, the upper part is the shell 10, and the lower part is the shell 70; a battery 80, a PCB board 90 and a lower seal 100 are arranged in the shell 70, the battery 80 is electrically connected to the PCB board 90 and the atomization assembly 20, the battery 80 is used to power the atomization assembly 20, the PCB board 90 is used to control the conduction of the circuit of the atomization assembly 20 and to charge the battery 80, and the plug-in end of the PCB board 90 is set toward the shell for charging; the lower seal 100 is arranged at the bottom of the battery 80 and is sealed with the shell 70, and the lower seal 100 is used to seal the battery 80 and the shell 70.

[0073] The other components of the electronic atomization device adopt existing technologies and will not be described in detail here.

[0074] The implementation of the present invention has the following beneficial effects: the electronic atomization device of the present invention is provided with two liquid storage tanks connected by channels, one of which is a flowing liquid tank storing atomized liquid, in which the atomized liquid flows under gravity, and the other is a non-flowing liquid tank filled with a porous liquid storage tank, and the atomized liquid is absorbed by the porous liquid storage tank, and the atomizing component is connected to the porous liquid storage tank, and the position of the atomizing component is arranged above the flowing liquid tank. Such a design has the following advantages: due to the existence of the non-flowing liquid tank, the liquid in the non-flowing liquid tank is absorbed by the porous liquid storage tank, and the atomizing core is absorbed by the porous liquid storage tank. The porous liquid storage is covered, so the atomizing core is less subject to the pressure of the atomized liquid's own weight, which is not easy to cause leakage of the atomized liquid. At the same time, the flowing liquid tank below can easily observe the amount of atomized liquid. Since users generally tilt the electronic atomizing device at a certain angle when using it, the liquid in the flowing liquid tank can enter the non-flowing liquid tank and be absorbed by the porous liquid storage tank. The liquid that the porous liquid storage tank can store can also be used by the atomizer for a period of time. When the electronic atomizing device needs to be charged or not in use, the liquid in the flowing liquid tank can also be replenished into the porous liquid storage tank when it is tilted or placed horizontally. This design is different from the original electronic atomizing device where the atomizing core is at the lowest position, so that the liquid in the flowing liquid tank will not leak due to the influence of its own gravity. It is also convenient to observe the remaining liquid amount and ensure the normal supply of atomized liquid.
