Double airway device and aerosol generating device for preventing hole blockage

Abstract

The present invention relates to the field of aerosol generating devices, and specifically discloses a dual airway device and an aerosol generating device for preventing hole blockage. By dividing the first airway of the microphone and the second airway generating aerosol into two independent flow channels, the condensate generated in the second airway cannot drip onto the microphone when refluxes, thereby avoiding the risk of short circuit. When the condensate refluxes and blocks the atomization component, the normal operation of the microphone enables the atomization component to start and heat normally, so that the oil blocked on the atomization component is heated to re-form an aerosol, thereby avoiding the blockage of the atomization component caused by the microphone being unable to start normally due to sharing an airway. There is an angle between the third airway and the second airway, so that when the aerosol generated in the second airway moves to the third airway through the suction force of the user, it needs to pass through the corner formed by the connection between the second airway and the third airway, which can block part of the condensate generated in the second airway, thereby preventing the user from sucking out the condensate during inhalation.

[0003] In the existing aerosol generating device, the start and stop of the microphone is controlled by the user's suction force. The microphone and the atomizer assembly share a ventilation pipe, so that the oil backflow of the aerosol generated by the atomizer assembly during condensation will cause blockage of the oil holes in the atomizer assembly.

[0009] Preferably, the second baffle is disposed between the air outlet and the first baffle; when the insertion portion is completely inserted into the air outlet, the first baffle is located at an end of the second air passage away from the atomization assembly.

[0010] Preferably, an inclined surface is provided between the end of the second air passage facing away from the atomization assembly and the second baffle.

[0011] Preferably, it also includes a bottom cover and an outer shell, the bottom cover is covered on one end of the outer shell, and a space for accommodating the first air duct, the second air duct, the third air duct, the air inlet, the microphone and the atomization component is formed in the outer shell; the air inlet is opened on the surface of the bottom cover; the microphone is arranged in the air inlet direction of the air inlet, and a bypass port is provided on the side of the bottom cover corresponding to the air inlet direction of the air inlet, and the bypass port is connected with the second air duct.

[0012] Preferably, oil-absorbing cotton is provided between the bypass port and the atomization assembly, and the oil-absorbing cotton is positioned on a side of the base close to the second airway.

[0013] Preferably, a battery cell and an oil storage shell are provided in the outer shell, the battery cell and the oil storage shell are arranged adjacent to each other, the first air passage is formed between the battery cell and the oil storage shell, and the second air passage is formed by the oil storage shell.

[0014] The present invention also provides an aerosol generating device, which comprises a double airway device for preventing hole blockage as described in any one of the above items.

[0015] Compared with the prior art, the dual airway device and aerosol generating device for preventing hole blockage provided by the present invention have the following advantages:

[0016] 1. By dividing the first airway of the microphone and the second airway where the aerosol is generated into two independent flow channels, the condensate generated in the second airway cannot drip onto the microphone when it flows back, thus avoiding the risk of short circuit. At the same time, when the condensate flows back and blocks the atomizer assembly, the normal operation of the microphone enables the atomizer assembly to start heating normally, so that the oil blocked on the atomizer assembly is heated and re-formed into an aerosol, thus avoiding the problem of blockage of the atomizer assembly caused by the microphone being unable to start normally due to sharing the same airway. There is an angle between the third airway and the second airway, so that when the aerosol generated in the second airway moves to the third airway through the user's suction, it needs to pass through the corner formed by the connection between the second airway and the third airway, which can block part of the condensate generated in the second airway, preventing the user from sucking out the condensate during inhalation, thereby improving the user's experience.

[0017] 2. The second air channel is arranged between the first air channel and the air outlet, that is, the second air channel is arranged close to the air outlet, so that the aerosol generated by the second air channel cannot enter the first air channel when the aerosol flows after being discharged by the user's suction, thereby avoiding the problem of the aerosol entering the first air channel after condensation, and further improving the stability of the microphone.

[0018] 3. By providing a detachable nozzle, the user can reuse the nozzle independently in multiple devices, so that the dual airway device for preventing hole blockage provided by this embodiment can be convenient for cross-use between users, and also avoid direct contact with the air outlet, thereby improving the safety of product use. In particular, when the device is used in a disposable aerosol generating device, the reusable nozzle can reduce production costs, reduce production difficulty, and improve production efficiency.

[0019] 4. The first baffle and the second baffle are set so that when the user inhales the aerosol, the condensed liquid attached to the inner wall of the third airway flows along the inner wall surface due to suction, and the first baffle and the second baffle can block the continued flow of the condensed liquid, further avoiding the problem of the condensed liquid flowing out of the third airway. The inclined first baffle and the second baffle can prevent the raised first baffle and the second baffle from reducing the exhaust diameter of the third airway while ensuring the effect of blocking the condensed liquid, thereby ensuring the ventilation volume of the third airway.

[0020] 5. By setting the position of the first baffle, when the condensate accumulates on the surface of the first baffle, the condensate will fall along the direction of the first baffle due to gravity. Based on the position of the first baffle corresponding to the second airway, the condensate falling from the first baffle can directly fall into the second airway, avoiding the accumulation of condensate at the position of the first baffle.

[0021] 6. By providing the inclined surface, the condensate accumulated at the second baffle can slide down into the second air passage based on the inclined surface, thereby avoiding the accumulation of the condensate at the second baffle position.

[0022] 7. By setting the microphone head on the air inlet direction and setting the bypass port on the side of the air inlet direction, the condensate cannot drip into the air inlet when falling, avoiding leakage of condensate and improving the safety of product use. At the same time, the external gas entering the air inlet can directly contact the microphone head, making the microphone head more sensitive in controlling the atomization component and improving the user experience.

[0023] 8. By providing the oil-absorbing cotton, the condensed liquid or insufficiently heated oil in the second air passage can be absorbed by the oil-absorbing cotton when dripping, thereby avoiding oil accumulation or splashing and improving the protection of the device.

[0024] 9. By arranging the battery cell and the oil storage shell adjacent to each other to form independent first and second air passages, the storage space in the shell can be effectively utilized, so that the device has a smaller volume, which is particularly suitable for disposable aerosol generating devices and is convenient for use and carrying of the product.

[0037] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0038] Please combine Figure 1 and Figure 2 The first embodiment of the present invention provides a dual airway device 1 for preventing hole blockage, including a bottom cover 11 and an outer shell 12, wherein the bottom cover 11 covers one end of the outer shell 13, and a space p is formed in the outer shell 12 to accommodate a battery cell 100 and an oil storage shell 101. The battery cell 100 and the oil storage shell 101 are arranged adjacent to each other, a first airway 13 is formed between the battery cell and the oil storage shell, a second airway 14 is formed in the oil storage shell 101, and a third airway 15 is provided at one end of the oil storage shell 101.

[0039] It can be understood that the gap between the battery cell 100 and the oil storage shell 101 forms the first air channel 13, the oil storage shell 101 is a hollow cylindrical or quasi-cylindrical structure, and the oil storage shell 101 encloses the second air channel 14, and the oil storage shell 101 is used to store oil.

[0040] The dual airway device 1 for preventing hole blockage further includes a microphone 16 and an atomizer assembly 17. An air inlet 111 is provided on the bottom cover 11. The air inlet 111 is respectively connected to one end of the first airway 13 and the second airway 14, and the third airway 15 is respectively connected to the other end of the first airway 13 and the second airway 14. The microphone 16 is arranged at one end of the first airway 13 close to the air inlet 111, the atomizer assembly 17 is arranged at one end of the second airway 14 close to the air inlet 111, and one end of the third airway 15 is connected to the outside. The user inhales the aerosol generated by the atomizer assembly 17 in the second airway 14 through the third airway 15.

[0041] It can be understood that the atomizing assembly 17 is in communication with the oil storage shell 101 , so that the oil in the oil storage shell 101 enters the atomizing assembly 17 to be heated and atomized to form an aerosol, and then is output to the second air passage 14 .

[0042] There is an angle a between the third airway 15 and the second airway 14. Specifically, the angle range is 90°<a<150°, wherein the angle is preferably 90°, 100°, 120° or 150°. In this embodiment, the angle a is 90° (eg Figure 2 The aerosol generated in the second air channel 14 needs to pass through the corner formed at the connection between the second air channel 14 and the third air channel 15 when it moves to the third air channel 15 through the suction force of the user, which can block part of the condensate generated in the second air channel 14, thereby preventing the user from sucking out the condensate during inhalation, thereby improving the user's experience.

[0043] It can be understood that when the user inhales through the third air channel 15, gas enters from the air inlet 111, part of the gas passes through the microphone 16 and enters the first air channel 13, so that the microphone 16 starts to drive the atomization component 17 to work, that is, the oil is heated in the second air channel 14 to generate an aerosol, and another part of the gas enters the second air channel 15, and the aerosol generated in the second air channel 15 is sent to the third air channel 16 based on the gas flow, and finally enters the user's mouth through the third air channel 16.

[0044] By dividing the first airway 13 of the microphone 16 and the second airway 14 for generating aerosol into two independent flow channels, the condensate for generating aerosol in the second airway 14 cannot drip onto the microphone 16 when it flows back, thus avoiding the risk of short circuit. At the same time, when the condensate flows back and blocks the atomizing assembly 17, the normal operation of the microphone 16 enables the atomizing assembly 17 to start heating normally, so that the oil blocked on the atomizing assembly 17 is heated to re-form aerosol, thus avoiding the problem of blockage of the atomizing assembly 17 caused by the microphone 16 not being able to start normally due to sharing the same airway.

[0045] In particular, in this embodiment, by arranging the battery cell 100 and the oil storage shell 101 adjacent to each other to form an independent first air channel 13 and a second air channel 14, the storage space in the outer shell 12 can be effectively utilized, so that the device has a smaller volume, which is particularly suitable for use in a disposable aerosol generating device, making it convenient to use and carry the product.

[0046] Please continue to combine Figure 1 and Figure 2 The third air channel 15 is provided with an air outlet 151 at one end, and the air outlet 151 contacts the user to discharge the aerosol into the user's oral cavity. The second air channel 14 is provided between the first air channel 13 and the air outlet 151, that is, the second air channel 14 is provided close to the air outlet 151, so that the aerosol generated by the second air channel 14 cannot enter the first air channel 13 when it flows after being discharged by the user's suction force, thereby avoiding the problem of the aerosol entering the first air channel 13 after condensation, and further improving the stability of the microphone 16.

[0047] Please combine Figure 1 , Figure 2 and Figure 3 The microphone 16 is arranged in the air inlet direction of the air inlet 111, that is, the microphone 16 is arranged opposite to the air inlet 111. A bypass port 112 is arranged on the side of the bottom cover 11 corresponding to the air inlet direction of the air inlet 111, and the bypass port 112 is connected to the second air channel 14, that is, after the external air enters through the air inlet 111, part of the air flows upward (such as Figure 2 b direction) enters the first airway 13 through the microphone 16, and the other part of the gas flows from the bypass port 112 to the side direction (such as Figure 3 c direction) into the second air passage 14 of the atomization assembly 17.

[0048] It can be understood that by arranging the microphone 16 in the air inlet direction of the air inlet 111 and arranging the bypass port 112 on the side of the air inlet direction of the air inlet 111, the condensate cannot drip into the air inlet 111 when falling, thus preventing the condensate from leaking out and improving the safety of the product. At the same time, the external air entering the air inlet 111 can directly contact the microphone 16, making the microphone 16 more sensitive in controlling the atomization assembly 17 and improving the user experience.

[0049] Please continue reading Figure 1 An oil-absorbing cotton 113 is provided between the bypass port 112 and the atomizing assembly 17. The oil-absorbing cotton 113 is positioned on the side of the base 11 close to the second air channel 14, so that when condensed liquid or insufficiently heated oil in the second air channel 14 drips, it can be absorbed by the oil-absorbing cotton 113, thereby avoiding oil accumulation or splashing and improving the protection of the device.

[0050] Please combine Figure 4 and Figure 5 The air outlet 151 is also provided with a suction nozzle 18, which is inserted into the air outlet 151. The suction nozzle 18 includes an insertion portion 181 and a supporting portion 182, wherein the supporting portion 182 is exposed at the air outlet 151 and the insertion portion 182 is inserted into the air outlet 151. When the insertion portion 182 is inserted into the air outlet 151 so that the supporting portion 182 is supported on the air outlet 151, the insertion portion 182 is completely inserted into the air outlet 151.

[0051] It can be understood that by providing a detachable nozzle 18, the user can reuse the nozzle 18 independently in multiple devices, so that the dual airway device 1 for preventing hole blockage provided in this embodiment can be convenient for cross-use between users, and also avoid direct contact with the air outlet 151, thereby improving the safety of product use. In particular, when the device is used in a disposable aerosol generating device, the reusable nozzle 18 can reduce production costs, reduce production difficulty, and improve production efficiency.

[0052] Please continue to combine Figure 4 and Figure 5 The inner wall surface of the insertion portion 182 is provided with a protruding first baffle 1811 and a second baffle 1812, the first baffle 1811 and the second baffle 1812 are inclined away from the air outlet 151, and the first baffle 1811 and the second baffle 1812 do not contact each other, so that the flowing aerosol can pass through the gap formed between the first baffle 1811 and the second baffle 1812.

[0053] When in use, after the aerosol flows through the third airway 15, some condensate will be generated on the inner wall surface of the third airway 15. The first baffle 1811 and the second baffle 1812 are provided so that when the user inhales the aerosol, the condensate attached to the inner wall of the third airway 15 flows along the inner wall surface due to suction, and the first baffle 1811 and the second baffle 1812 can block the continued flow of the condensate, further avoiding the problem of the condensate flowing out of the third airway 15. The first baffle 1811 and the second baffle 1812 are arranged obliquely, while ensuring the blocking of the condensate, to avoid the raised first baffle 1811 and the second baffle 1812 from reducing the exhaust diameter of the third airway 15, thereby ensuring the ventilation volume of the third airway 15.

[0054] Optionally, as an embodiment, the second baffle 1812 is disposed between the air outlet 151 and the first baffle 1811 , and when the insertion portion 182 is completely inserted into the air outlet 151 , the first baffle 1811 is located at an end of the second air passage 14 away from the atomization assembly 17 .

[0055] It can be understood that when condensate accumulates on the surface of the first baffle 1811, the condensate will fall along the direction of the first baffle 1811 due to gravity, and based on the position of the first baffle 1811 corresponding to the second air duct 14, the condensate falling from the first baffle 1811 can directly fall into the second air duct 14, avoiding the accumulation of condensate at the position of the first baffle 1811.

[0056] Optionally, as another embodiment, a slope q is provided between the end of the second air channel 14 facing away from the atomization assembly 17 and the second baffle 1812 , so that condensate accumulated at the second baffle 1812 can slide into the second air channel 14 based on the slope q, thereby avoiding accumulation of condensate at the second baffle 1812 .

[0057] The second embodiment of the present invention provides an aerosol generating device, which includes the dual airway device 1 for preventing hole blockage provided in the first embodiment. The aerosol generating device is suitable for oil-filled reusable equipment and can also be used in disposable single-use equipment.

[0058] Compared with the prior art, the double airway device for preventing hole blockage provided by the present invention has the following advantages:

[0059] By dividing the first airway of the microphone and the second airway where the aerosol is generated into two independent flow channels, the condensate generated in the second airway cannot drip onto the microphone when it flows back, thus avoiding the risk of short circuit. At the same time, when the condensate flows back and blocks the atomizer assembly, the normal operation of the microphone enables the atomizer assembly to start heating normally, so that the oil blocked on the atomizer assembly is heated to re-form aerosol, thus avoiding the problem of blockage of the atomizer assembly caused by the microphone being unable to start normally due to sharing the same airway. There is an angle between the third airway and the second airway, so that when the aerosol generated in the second airway moves to the third airway through the user's suction, it needs to pass through the corner formed by the connection between the second airway and the third airway, which can block part of the condensate generated in the second airway, preventing the user from sucking out the condensate during inhalation, thereby improving the user's experience.

[0060] The foregoing description of specific exemplary embodiments of the present invention is for the purpose of illustration and demonstration. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art can realize and utilize various different exemplary embodiments of the present invention and various different selections and changes. The scope of the present invention is intended to be limited by the claims and their equivalents.
