Description

Technical field

[0001] The utility model relates to the technical field of atomizers, in particular to an atomization device and an electronic atomizer. [Background Technology]

[0002] Electronic vaporizers use electronic technology to heat the stored liquid to be atomized to generate vapor, reducing the harmful emissions found in traditional cigarettes and gaining popularity among consumers. However, due to their complex internal structure, which includes multiple key components such as the atomizer assembly, oil storage assembly, and control assembly, the air pressure inside the electronic vaporizer can fluctuate during transportation due to changes in the external environment, such as temperature fluctuations and air pressure differences. This pressure fluctuation can cause a number of problems, the most common of which are self-priming and oil leakage.

[0003] Self-priming typically occurs when the air pressure inside an electronic atomizer changes dramatically, causing the control system to misjudge and prematurely activate the heating element, causing the e-liquid to evaporate even when not in use. This not only wastes the e-liquid but can also damage the atomizer itself. Leakage is even more common and can be caused by a variety of factors, such as worn rubber seals and vibration during transportation. Leakage not only affects the user experience of the atomizer but can also pollute the surrounding environment.

[0004] To address this technical issue, existing electronic atomizers have introduced some blocking structures to block the air inlet and oil tank outlet, serving as an effective barrier to prevent self-priming and oil leakage. However, the blocking effect of existing blocking structures is not obvious and cannot effectively prevent self-priming and oil leakage in electronic atomizers. [Utility Model Content]

[0005] In order to solve the problem of unsatisfactory blocking effect of the blocking structure of the existing electronic atomizer, the utility model provides an atomization device and an electronic atomizer.

[0006] The solution to the technical problem solved by the present invention is to provide an atomizing device, comprising a shell, an atomizing assembly and a support member arranged in the shell, a bottom shell clamped with the shell, and a sealing structure, an air flow channel is formed in the atomizing assembly, a suction nozzle opening is provided at one end of the shell corresponding to the air flow channel, a plug is detachably provided in the suction nozzle opening, the support member is provided on a side of the atomizing assembly away from the suction nozzle opening, and a coaxial first through hole and a second through hole are respectively provided on the support member and the bottom shell corresponding to the end of the air flow channel away from the suction nozzle opening; the sealing structure comprises a sealing portion, the sealing portion comprises a supporting section, a breaking section and a sealing section connected in sequence, the sealing section of the sealing portion passes through the second through hole into the first through hole and blocks the first through hole, and the diameter of at least part of the sealing section is larger than the diameter of the first through hole.

[0007] Preferably, at least one annular protrusion is provided on the blocking section.

[0008] Preferably, the diameters of the supporting segment and the blocking segment are both larger than the diameter of the fracture segment.

[0009] Preferably, the blocking structure further includes an external portion connected to the supporting section of the blocking portion.

[0010] Preferably, a boss is provided on the inner wall of the bottom shell around the second through hole, and the boss is hollow to form an accommodating space. When the peripheral part is pulled away, the blocking section detaches from the first through hole and enters the accommodating space.

[0011] Preferably, the inner diameter of the accommodating space is equal to the diameter of the first through hole.

[0012] Preferably, the inner diameter of the second through hole is smaller than the inner diameter of the accommodating space.

[0013] Preferably, the bottom shell is provided with an air intake column avoiding the second through hole, the inner wall of the bottom shell and the support member form a cavity, and oil-absorbing cotton is provided in the cavity close to the inner wall of the bottom shell, and the thickness of the oil-absorbing cotton does not exceed the height of the air intake column protruding relative to the inner wall of the bottom shell.

[0014] In order to solve the above technical problems, the present utility model provides another technical solution as follows: an electronic atomizer, comprising a battery assembly and the above-mentioned atomization device, the atomization assembly comprising an atomization core and a heating wire pin, one end of the heating wire pin being connected to the atomization core, and the other end being connected to the battery assembly.

[0015] Preferably, a fixing member is provided at one end of the support member close to the atomizer assembly, and a third through hole is opened on the fixing member corresponding to the first through hole. The end of the heating wire pin away from the atomizer core passes through the first through hole and the third through hole to be connected to the battery assembly.

[0016] Compared with the prior art, the atomization device and electronic atomizer provided by the present invention have the following advantages:

[0017] The atomizing device provided in the embodiment of the present invention has a plug detachably provided in the mouthpiece, and the blocking section of the blocking structure passes through the second through hole into the first through hole and blocks the first through hole. The first through hole and the mouthpiece are respectively arranged corresponding to the two ends of the air flow channel of the atomizing assembly, and the first through hole and the mouthpiece are blocked by the blocking section and the plug respectively, that is, both ends of the air flow channel are blocked. The air flow channel is the only channel for the exchange of the internal air pressure of the atomizing device with the external environment. When both ends of the air flow channel are blocked, the influence of the external environment air pressure fluctuation on the internal air pressure of the atomizing device can be effectively blocked, and the self-starting phenomenon caused by the air pressure change can be effectively reduced. At the same time, the sealing performance of the atomizing device is enhanced, and the risk of the liquid to be atomized stored in the oil cup shell overflowing from the air flow channel is greatly reduced, which can effectively avoid the risk of oil leakage during transportation. The blocking portion is designed to be connected in sequence with a supporting section, a breaking section and a blocking section, and the diameter of at least part of the blocking section is larger than the diameter of the first through hole, which improves the sealing performance and enables the blocking section to achieve a tight seal on the first through hole. The supporting section supports the blocking section to enter the first through hole through the second through hole, and when the blocking section needs to be removed, a pulling force can be applied to the supporting section to pull the blocking section out of the first through hole, and the breaking section is broken under the force, so that the blocking section is separated from the breaking section and remains inside the atomizing device to further block the second through hole, thereby preventing condensed water from overflowing from the second through hole.

[0018] In the electronic atomizer provided in the embodiment of the present invention, a fixing member is provided at one end of the support member close to the atomizer assembly, and a third through hole is provided on the fixing member corresponding to the first through hole. The end of the heating wire pin away from the atomizer core passes through the first through hole and the third through hole to connect to the battery assembly. The fixing member and the support member jointly fix the heating wire pin, preventing the heating wire pin from being displaced during transportation or use, thereby affecting the operation of the atomizer core, and improving the overall reliability and safety of the electronic atomizer. The electronic atomizer also includes all the beneficial effects of the atomizer device, which will not be repeated here.

[0039] Please combine Figure 1 and Figure 2The first embodiment of the present invention provides an atomizing device 1, comprising a shell 10, an atomizing assembly 11 and a support member 12 arranged in the shell 10, a bottom shell 13 clamped with the shell 10, and a blocking structure 14. An air flow channel 110 is formed in the atomizing assembly 11, and a suction nozzle 100 is opened at one end of the shell 10 corresponding to the air flow channel 110. A plug 1000 is detachably provided in the suction nozzle 100, and the support member 12 is arranged on a side of the atomizing assembly 11 away from the suction nozzle 100. A coaxial first through hole 120 and a second through hole 130 are respectively opened at one end of the support member 12 and the bottom shell 13 corresponding to the air flow channel 110 away from the suction nozzle 100.

[0040] Please see further Figure 3a and Figure 3b The blocking structure 14 includes a blocking portion 140, which includes a supporting segment 1400, a breaking segment 1401 and a blocking segment 1402 connected in sequence. The blocking segment 1402 of the blocking portion 140 passes through the second through hole 130 into the first through hole 120 and blocks the first through hole 120. The diameter of at least part of the blocking segment 1402 is larger than the diameter of the first through hole 120.

[0041] It can be understood that the first through hole 120 and the suction nozzle 100 are respectively arranged corresponding to the two ends of the air flow channel 110 of the atomizing assembly 11, and the first through hole 120 and the suction nozzle 100 are respectively blocked by the blocking section 1402 and the plug 1000, that is, both ends of the air flow channel 110 are blocked. The air flow channel 110 serves as a necessary channel for the exchange of the internal air pressure of the atomizing device 1 with the external environment. When both ends of the air flow channel 110 are blocked, the influence of the external environment air pressure fluctuation on the internal air pressure of the atomizing device 1 can be effectively blocked, and the self-starting phenomenon caused by the air pressure change can be effectively reduced.

[0042] Please see further Figure 4 The atomizing device 1 further includes an oil cup shell 17 arranged between the outer shell 10 and the atomizing assembly 11, an oil storage cotton 18 arranged in the oil cup shell 17, and a sealing member 19 arranged at one end of the oil cup shell 17 away from the support member 12. The sealing member 19 has a through hole corresponding to the air flow channel 110, and the through hole connects the air flow channel 110 and the suction nozzle 100.

[0043] As can be understood, the oil cup housing 17 is a tubular structure with openings at both ends. One end is connected to the support member 12, and the other end is connected to the seal 19. The seal 19 and the support member 12 seal the oil cup housing 17, preventing the atomized liquid stored in the oil reservoir 18 from spilling out. The oil reservoir 18 absorbs and stores the liquid awaiting atomization, ensuring a constant supply of atomized liquid in the atomizing device 1. The size and shape of the oil cup housing 17 and the oil reservoir 18 match each other, ensuring a tight fit.

[0044] It can be understood that the first through hole 120 and the suction nozzle 100 are respectively blocked by the blocking section 1402 and the plug 1000, that is, both ends of the air flow channel 110 are blocked, which also enhances the sealing performance of the atomization assembly 11, greatly reduces the risk of the liquid to be atomized stored in the oil cup shell 17 overflowing from the air flow channel 110, and can effectively avoid the risk of oil leakage during transportation.

[0045] It can be understood that the blocking portion 140 is designed to be a supporting section 1400, a breaking section 1401 and a blocking section 1402 connected in sequence. The supporting section 1400 supports the blocking section 1402 to pass through the second through hole 130 into the first through hole 120, and when the blocking section 1402 needs to be removed, a pulling force can be applied to the supporting section 1400 to pull the blocking section 1402 out of the first through hole 120, and the breaking section 1401 is broken under the force, so that the blocking section 1402 is separated from the breaking section 1401 and remains inside the atomizing device 1 to further block the second through hole 130, thereby preventing condensed water from overflowing from the second through hole 130.

[0046] It can be understood that at least part of the diameter of the blocking section 1402 is larger than the diameter of the first through hole 120, so that the blocking section 1402 can achieve a tight seal on the first through hole 120, improve the sealing performance, and more effectively prevent the atomization device 1 from self-starting and oil leakage.

[0047] Please continue reading Figure 3a and Figure 3b At least one annular protrusion 1403 is provided on the blocking section 1402 .

[0048] As can be understood, the design of annular protrusion 1403 allows sealing section 1402 to more tightly seal first through-hole 120, and increases the friction between sealing section 1402 and the inner wall of first through-hole 120, preventing the sealing section 1402 from loosening due to bumps and vibrations during transportation, thereby enhancing the sealing reliability. Furthermore, annular protrusion 1403 has a simple structure and is easy to manufacture.

[0049] It can be understood that the function of the annular protrusion 1403 is to increase friction and make the sealing tighter, so other shapes can also be set on the peripheral side of the sealing section 1402 to achieve the same effect.

[0050] Furthermore, the diameters of the supporting segment 1400 and the blocking segment 1402 are both larger than the diameter of the fracture segment 1401 .

[0051] It can be understood that when a pulling force is applied to the supporting section 1400 to pull out the blocking section 1402, the breaking section 1401 has less toughness and strength and the stress is concentrated in this area, making it easier to break, so that the blocking section 1402 can remain on the inner wall of the atomizing device 1 and continue to play a role, blocking the first through hole 120 to prevent condensed water from flowing out.

[0052] It can be understood that the breaking segment 1401 can be further designed into a truncated cone-shaped structure, with the end with a smaller diameter connected to the blocking segment 1402 and the end with a larger diameter connected to the supporting segment 1400, so that when the breaking segment 1401 breaks, it can guide the direction of the break and break off from the end close to the blocking segment 1402, thereby reducing damage to the blocking structure and improving the overall appearance quality of the product to meet users' needs for aesthetics.

[0053] Furthermore, the blocking structure 14 also includes an external portion 141 connected to the supporting section 1400 of the blocking portion 140 .

[0054] It is understandable that the external portion 141 can prevent the entire blocking portion 140 from entering the interior of the electronic cigarette and being unable to be removed. At the same time, the configuration of the external portion 141 can better grip and apply tension to the support section 1400. In this embodiment, the specific shape of the external portion 141 is not limited.

[0055] Please combine Figure 2 、 Figure 5 and Figure 6 The inner wall of the bottom shell 13 is provided with a boss 131 protruding inward around the second through hole 130 , and the boss 131 is hollow to form an accommodating space 132 . When the peripheral part 141 is pulled away, the blocking section 1402 detaches from the first through hole 120 and enters the accommodating space 132 .

[0056] It is understandable that the blocking section 1402 can function a second time after being separated from the first through hole 120, blocking the accommodating space 132 connected to the second through hole 130. During use of the atomizing device 1, especially under conditions of frequent use or large fluctuations in ambient temperature, the hot vapor will partially condense into condensate as it cools. The second through hole 130 is arranged corresponding to the airflow channel 110, so the condensate is easily discharged from the second through hole 130, affecting the user experience. Blocking the accommodating space 132 can effectively prevent the condensate generated in the airflow channel 110 from flowing out of the second through hole 130.

[0057] Furthermore, the inner diameter of the accommodating space 132 is equal to the diameter of the first through hole 120 .

[0058] It can be understood that the inner diameter of the accommodating space 132 is consistent with the diameter of the first through hole 120, ensuring that at least part of the diameter of the sealing section 1402 is larger than the inner diameter of the accommodating space 132, so that when the sealing section 1402 seals the accommodating space 132 for the second time, it can still achieve tight sealing and effectively prevent condensation water from overflowing from the second through hole 130.

[0059] Furthermore, the inner diameter of the second through hole 130 is smaller than the inner diameter of the accommodating space 132 .

[0060] Understandably, this design creates a step between the second through-hole 130 and the accommodating space 132. When a tensile force is applied to the supporting section 1400, the step exerts a force opposite to the tensile force on the blocking section 1402, making it easier for the breaking section 1401 to break, thus ensuring that the blocking section 1402 can remain within the accommodating space 132 and provide a seal. This also ensures that during use, the blocking section 1402 will not slide due to reduced friction between the blocking section 1402 and the inner wall of the accommodating space 132 caused by condensation, etc., nor will it fall off due to bumps or vibrations.

[0061] Preferably, the overall diameter of the blocking section 1402 should be larger than the inner diameter of the second through hole 130, so that it can better separate from the broken section 1401. At the same time, the blocking section 1402 as a whole can stay in the accommodating space 132, which can better block the second through hole 130 and be more aesthetically pleasing.

[0062] Furthermore, the bottom shell 13 is provided with an air intake column 133 avoiding the second through hole 130, and the inner wall of the bottom shell 13 and the support member 12 form a cavity 15. Oil-absorbing cotton 16 is provided in the cavity 15 close to the inner wall of the bottom shell 13, and the thickness of the oil-absorbing cotton 16 does not exceed the height of the air intake column 13 protruding relative to the inner wall of the bottom shell 13.

[0063] It can be understood that in the working room of the atomizing device 1, the air inlet column 133 is used to introduce external air, and the oil-absorbing cotton 16 serves as a protective layer to prevent the liquid to be atomized from overflowing or leaking, while effectively absorbing the condensate inside the atomizing component 11, thereby extending the service life of the entire equipment and reducing the need for frequent cleaning.

[0064] It can be understood that the thickness of the oil-absorbing cotton 16 does not exceed the height of the air inlet column 133 protruding relative to the inner wall of the bottom shell 13, which can effectively prevent the liquid to be atomized or condensed liquid absorbed by the oil-absorbing cotton 16 from overflowing through the air inlet column 133, thereby affecting the user experience and further improving the overall reliability and safety of the equipment.

[0065] Please further combine Figure 3b Optionally, a plunger 1410 may be further provided on the side where the peripheral portion 141 connects to the support section 1400. The position, shape, and size of the plunger 1410 match the air inlet column 133. When the blocking section 1402 blocks the first through hole 120, the plunger 1410 simultaneously enters the air inlet column 133 to seal it. The provision of the plunger 1410 further enhances the airtightness of the atomizing device 1, reduces the impact of external ambient air pressure fluctuations on the internal air pressure of the atomizing device 1, and effectively reduces the self-priming phenomenon caused by air pressure fluctuations.

[0066] See also Figure 7 and Figure 8The second embodiment of the present invention provides an electronic atomizer 2, comprising a battery assembly 21 and the above-mentioned atomization device 1, wherein the atomization assembly 11 comprises an atomization core 111 and a heating wire pin 112, wherein one end of the heating wire pin 112 is connected to the atomization core 111, and the other end is connected to the battery assembly 21.

[0067] It can be understood that the battery assembly 21 is used to power the atomizer device 1, and the atomizer core 111 is used to heat the atomized liquid and atomize it into vapor. The battery assembly 21 further includes a battery and a PCB board electrically connected to the battery. A control circuit is provided on the PCB board, and the heating wire pin 112 is electrically connected to the control circuit, thereby realizing the control circuit of the atomizer core 111.

[0068] Furthermore, a fixing member 22 is provided at one end of the support member 12 close to the atomizer assembly 11 , and a third through hole 220 is opened on the fixing member 22 corresponding to the first through hole 120 . The end of the heating wire pin 112 away from the atomizer core 111 passes through the first through hole 120 and the third through hole 220 to be connected to the battery assembly 21 .

[0069] It can be understood that the fixing member 22 and the supporting member 12 jointly fix the heating wire pin 112, preventing the heating wire pin 112 from being displaced during transportation or use, thereby affecting the operation of the atomizer core 111, and improving the overall reliability and safety of the electronic atomizer 2.

[0070] It can be understood that the electronic atomizer 2 also includes all the beneficial effects of the atomization device 1, which will not be repeated here.

[0071] Compared with the prior art, the atomization device and electronic atomizer provided by the present invention have the following advantages:

[0072] 1. The atomizing device provided in the embodiment of the present invention has a plug detachably provided in the mouthpiece, and the blocking section of the blocking structure passes through the second through hole into the first through hole and blocks the first through hole. The first through hole and the mouthpiece are respectively arranged corresponding to the two ends of the air flow channel of the atomizing assembly. The first through hole and the mouthpiece are blocked by the blocking section and the plug respectively, that is, both ends of the air flow channel are blocked. The air flow channel is the only channel for the exchange of the internal air pressure of the atomizing device with the external environment. When both ends of the air flow channel are blocked, the influence of the external environment air pressure fluctuation on the internal air pressure of the atomizing device can be effectively blocked, and the self-starting phenomenon caused by the air pressure change can be effectively reduced. At the same time, the sealing performance of the atomizing device is enhanced, and the risk of the liquid to be atomized stored in the oil cup shell overflowing from the air flow channel is greatly reduced, which can effectively avoid the risk of oil leakage during transportation. The blocking portion is designed to be a supporting section, a breaking section and a blocking section connected in sequence, and the diameter of at least part of the blocking section is larger than the diameter of the first through hole, which improves the sealing performance and enables the blocking section to achieve a tight seal on the first through hole. The supporting section supports the blocking section to enter the first through hole through the second through hole, and when the blocking section needs to be removed, a pulling force can be applied to the supporting section to pull the blocking section out of the first through hole, and the breaking section is broken under the force, so that the blocking section is separated from the breaking section and remains inside the atomizing device to further block the second through hole, thereby preventing condensed water from overflowing from the second through hole.

[0073] 2. The atomizing device provided in the embodiment of the present invention is provided with at least one annular protrusion on the sealing section. The design of the annular protrusion makes the sealing section seal the first through hole more tightly, and increases the friction between the sealing section and the inner wall of the first through hole, so that it will not loosen due to bumps and vibrations during transportation, thereby enhancing the reliability of the sealing.

[0074] 3. In the atomization device provided in the embodiment of the present invention, the diameters of the supporting section and the blocking section are both larger than the diameter of the breaking section. When a tensile force is applied to the supporting section to pull out the blocking section, the breaking section is more likely to break due to its lower toughness and strength and the stress is concentrated in this area, so that the blocking section can remain on the inner wall of the electronic atomization device and continue to function.

[0075] 4. The atomizing device provided in the embodiment of the present invention has a blocking structure which further includes an external portion connected to the supporting section of the blocking portion. The external portion can prevent the entire blocking portion from entering the interior of the electronic cigarette and being unable to be removed. At the same time, the setting of the external portion can better grip the supporting section to apply tension.

[0076] 5. In the atomizing device provided in the embodiment of the present invention, a boss is provided on the inner wall of the bottom shell surrounding the second through hole and protruding inwardly. The boss is hollow to form an accommodating space. When the peripheral part is pulled away, the blocking section detaches from the first through hole and enters the accommodating space. After detaching from the first through hole, the blocking section can still function a second time to block the accommodating space connected to the second through hole. During the use of the atomizing device, especially in the case of frequent use or large changes in ambient temperature, the hot vapor will partially condense into condensate when cooling. The second through hole is arranged corresponding to the air flow channel. Therefore, the condensate is easy to flow out of the second through hole, affecting the user experience. Blocking the accommodating space can effectively prevent the condensate generated in the air flow channel from flowing out of the second through hole.

[0077] 6. In the atomization device provided in the embodiment of the present invention, the inner diameter of the accommodating space is equal to the diameter of the first through hole, which ensures that at least part of the diameter of the blocking section is larger than the inner diameter of the accommodating space, so that the blocking section can achieve a tight seal on the accommodating space.

[0078] 7. In the atomizing device provided in the embodiment of the present invention, the inner diameter of the second through hole is smaller than the inner diameter of the accommodating space. This design creates a step between the second through hole and the accommodating space. When a tensile force is applied to the supporting section, the step applies a force opposite to the tensile force to the blocking section, making it easier for the breaking section to break, ensuring that the blocking section can remain within the accommodating space to block the liquid. This also ensures that during use, the blocking section will not slip due to reduced friction between the blocking section and the inner wall of the accommodating space caused by condensation, etc., nor will it fall off due to bumps or vibrations.

[0079] 8. In the atomizer device provided in the embodiments of the present invention, the oil-absorbing cotton acts as a protective layer, preventing the atomized liquid from overflowing or leaking. It also effectively absorbs condensate within the atomizer assembly, extending the service life of the entire device and reducing the need for frequent cleaning. The thickness of the oil-absorbing cotton does not exceed the height of the protrusion of the air inlet column relative to the inner wall of the bottom shell. This effectively prevents the atomized liquid or condensate absorbed by the oil-absorbing cotton from overflowing through the air inlet column, further improving the overall reliability and safety of the device.

[0080] 9. In the electronic atomizer provided in the embodiment of the present invention, a fixing member is provided at one end of the support member close to the atomizer assembly. The fixing member is provided with a third through hole corresponding to the first through hole. The end of the heating wire pin away from the atomizer core passes through the first through hole and the third through hole to connect to the battery assembly. The fixing member and the support member jointly fix the heating wire pin, preventing the heating wire pin from being displaced during transportation or use, thereby affecting the operation of the atomizer core, and improving the overall reliability and safety of the electronic atomizer. The electronic atomizer also includes all the beneficial effects of the atomizer device, which will not be repeated here.

[0081] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the principles of the present invention should be included in the scope of protection of the present invention.
