Atomizer and aerosol generating device

Abstract

This invention provides an atomizer and an aerosol generating device. In the atomizer structure, an atomizing element and an airflow splitter are arranged inside the atomizing cartridge body. A mixing chamber is provided between the atomizing element and the airflow splitter. The atomizing element has a vent hole connecting the mixing chamber and the airflow channel. The airflow splitter has a first guide channel and a second guide channel. When the user inhales, external air introduced through the air inlet of the atomizing cartridge body is partially dispersed into the mixing chamber through the first guide channel, quickly and fully carrying the aerosol in the mixing chamber to the vent hole. Simultaneously, another portion of the air is concentrated and introduced into the vent hole through the second guide channel, converging with the aerosol-carrying mixed air and flowing into the vent hole. This allows the aerosol-carrying airflow to be quickly guided to the outlet through the airflow channel, reducing aerosol loss on the walls, in bends, and in airflow stagnation areas, improving aerosol carrying efficiency, and preventing a decrease in aerosol concentration.

[0002] Aerosol generating devices typically include an atomizer and a power supply electrically connected to the atomizer. Driven by the power supply, the atomizer heats and atomizes the liquid stored within it to form an aerosol. In current atomizer designs, airflow is easily affected by bends in the air intake channel and airflow stagnation areas, resulting in significant aerosol loss and a decrease in aerosol concentration. This leads to insufficient aroma reproduction and intensity, resulting in a poor taste experience for the user and negatively impacting the overall user experience. Summary of the Invention

[0003] Based on the aforementioned problems in the prior art, one of the objectives of this invention is to provide an atomizer to solve the problem that the airflow is easily affected by the bends in the air intake channel and the airflow stagnation area, resulting in a large loss of aerosols carried by the airflow and a decrease in aerosol concentration.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: to provide an atomizer, comprising:

[0005] The atomizing bullet body has an internal storage chamber for storing atomizing liquid. The atomizing bullet body has an air inlet, an air outlet, an air guide channel communicating with the air outlet, and a liquid guide port communicating with the storage chamber.

[0006] An atomizing element, used to atomize a liquid into an aerosol, is disposed inside the atomizing bullet body; the liquid in the storage chamber can be transferred to the atomizing element via the liquid guide port; and

[0007] An airflow diverter is disposed inside the atomizing bullet body at a position corresponding to the atomizing element;

[0008] The atomizing element and the airflow splitter are provided with a mixing chamber. The aerosol formed by the atomizing element can be released into the mixing chamber. The atomizing element is provided with a vent hole that connects the mixing chamber and the air guide channel. The airflow splitter is provided with a first guide channel for dispersively introducing airflow into the mixing chamber and a second guide channel for concentrating airflow into the vent hole. The first guide channel and the second guide channel are respectively connected to the air inlet.

[0009] Furthermore, the second guide channel is a straight central channel directly opposite the vent, and the first guide channel is an annular channel surrounding the central channel.

[0010] Furthermore, the ratio of the flow cross-sectional area of ​​the first guide channel to the flow cross-sectional area of ​​the second guide channel is (4-9):1.

[0011] Furthermore, the atomizing element has an atomizing surface on the side facing the airflow splitter for heating the atomizing liquid and releasing aerosol, and the first guiding channel is an annular channel for guiding airflow toward the atomizing surface.

[0012] Furthermore, the annular channel is inclined radially outward.

[0013] Furthermore, the atomizing surface is an annular concave surface recessed on the atomizing element and surrounding the vent hole.

[0014] Furthermore, the airflow splitter is provided with multiple branch channels, which are arranged in a ring to form the annular channel, and the annular channel surrounds the second guide channel.

[0015] Furthermore, a nozzle is provided on the airflow splitter at the outlet corresponding to the second guide channel, the nozzle's air outlet is connected to the outlet of the second guide channel, and the nozzle's air outlet is directly opposite the vent.

[0016] Furthermore, the atomizing element is a porous ceramic heating element with micropores, and a liquid storage tank for storing atomizing liquid is provided on the side of the porous ceramic heating element facing away from the airflow diverting element, and the opening of the liquid storage tank is connected to the liquid guide port.

[0017] Based on the aforementioned problems in the prior art, a second objective of this invention is to provide an aerosol generating device having an atomizer as described in any of the above solutions.

[0018] To achieve the above objectives, the technical solution adopted by the present invention is to provide an aerosol generating device, including the atomizer provided by any of the above solutions.

[0019] Compared with the prior art, one or more technical solutions in the embodiments of the present invention have at least one of the following beneficial effects:

[0020] In the atomizer and aerosol generating device of the present invention, the atomizer structure includes an atomizing element and an airflow splitter inside the atomizing bullet body, a mixing chamber between the atomizing element and the airflow splitter, a vent on the atomizing element connecting the mixing chamber and the air guide channel, and a first guide channel for dispersively introducing airflow into the mixing chamber and a second guide channel for converging airflow into the vent. When the user inhales, the external air introduced through the air inlet of the atomizing cartridge is divided into two parts by the airflow splitter and flows to the vent of the atomizing component: one part of the air is dispersed into the mixing chamber through the first guide channel, and carries the aerosol in the mixing chamber quickly and fully to the vent; at the same time, the other part of the air is gathered into the vent through the second guide channel, and flows into the vent together with the air mixed with aerosol. This allows the airflow carrying aerosol to be quickly guided to the air outlet through the air guide channel, which can significantly reduce the loss of aerosol on the wall, in bends and in the airflow stagnation area, thereby improving the efficiency of the airflow carrying aerosol, preventing the aerosol concentration from decreasing, and thus ensuring that the aerosol has sufficient aroma reproduction and intensity, ensuring that the user has a better taste when inhaling the aerosol.

Therefore, the phrases "in one embodiment," "in some embodiments," or "in some of these embodiments" appear in various places throughout the specification, and not all refer to the same embodiment. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0041] Please refer to the following: Figures 1 to 7 The atomizer provided in the embodiments of the present invention will now be described. The atomizer provided in the embodiments of the present invention is applicable to aerosol generating devices. The aerosol generating device mentioned in the embodiments of the present invention generally includes an atomizer and a power supply device 5 electrically connected to the atomizer. When using the aerosol generating device, the power supply device 5 can provide electrical energy to the atomizer. Under the action of electric drive, the atomizing element 2 of the atomizer atomizes the atomizing liquid stored in the atomizer to form an aerosol that can be inhaled by the user.

[0042] Please refer to further details. Figure 1 , Figure 2 and Figure 3The atomizer provided in this embodiment of the invention includes an atomizing cartridge body 1, an atomizing element 2, and an airflow divider 3. The atomizing cartridge body 1 has a storage chamber 14 for storing atomized liquid. The atomizing cartridge body 1 has an air inlet 15 for introducing outside air, an air outlet 16 for the user to inhale aerosol, an air guide channel 17 communicating with the air outlet 16, and a liquid guide port 18 communicating with the storage chamber 14. The atomizing element 2 is disposed inside the atomizing cartridge body 1. The atomized liquid in the storage chamber 14 can be transferred to the atomizing element 2 via the liquid guide port 18. The atomizing element 2 can atomize the atomized liquid to form an aerosol. The atomizing element 2 can be, but is not limited to, a ceramic atomizing core capable of atomizing liquid to form an aerosol. The airflow divider 3 is disposed inside the atomizing cartridge body 1 at a position corresponding to the atomizing element 2. The airflow divider 3 can be, but is not limited to, a silicone component. A mixing chamber 19 is provided between the atomizing element 2 and the airflow splitter 3, and the aerosol formed by the atomization of the atomizing element 2 can be released into the mixing chamber 19. The atomizing element 2 is provided with a vent 21 connecting the mixing chamber 19 and the air guide channel 17. The shape of the vent 21 can be, but is not limited to, circular, elliptical, or square. The airflow splitter 3 is provided with a first guide channel 31 for dispersing the airflow into the mixing chamber 19 and a second guide channel 32 for concentrating the airflow into the vent 21. The first guide channel 31 and the second guide channel 32 are respectively connected to the air inlet 15. When the atomizer is in use, the user inhales through the air outlet 16. Under the action of suction negative pressure, outside air is first introduced through the air inlet 15. A portion of the introduced airflow is dispersed into the mixing chamber 19 through the first guide channel 31, and a portion of the introduced airflow is concentrated into the vent 21 through the second guide channel 32. A portion of the airflow is dispersedly introduced into the mixing chamber 19 through the first guide channel 31, where it is thoroughly mixed with the aerosol released into the mixing chamber 19 and carried to the vent 21. At this time, another portion of the airflow is concentrated and introduced into the vent 21 through the second guide channel 32, where it merges with the air mixed with the aerosol. The airflow carrying the aerosol is then transmitted linearly through the vent 21 to the air guide channel 17, which then guides the airflow carrying the aerosol to the air outlet 16, allowing the user to draw in the aerosol.

[0043] Compared with the prior art, the atomizer provided in this embodiment of the invention has an atomizing element 2 and an airflow splitter 3 arranged inside the atomizing bullet body 1. A mixing chamber 19 is provided between the atomizing element 2 and the airflow splitter 3. The atomizing element 2 is provided with a vent hole 21 that connects the mixing chamber 19 and the air guide channel 17. The airflow splitter 3 is provided with a first guide channel 31 for dispersively introducing airflow into the mixing chamber 19 and a second guide channel 32 for concentrating airflow into the vent hole 21. When the user inhales, the external air introduced through the air inlet 15 of the atomizing cartridge body 1 is divided into two parts by the airflow splitter 3 and flows to the vent 21 of the atomizing component 2: one part of the air is dispersed into the mixing chamber 19 through the first guide channel 31, and the aerosol in the mixing chamber 19 is quickly and fully carried to the vent 21. At the same time, the other part of the air is gathered into the vent 21 through the second guide channel 32, and flows into the vent 21 together with the air mixed with the aerosol. This allows the airflow carrying the aerosol to be quickly guided to the air outlet 16 through the air guide channel 17, which can significantly reduce the loss of aerosol on the wall, in bends and in the airflow stagnation area, thereby improving the efficiency of the airflow carrying the aerosol, preventing the aerosol concentration from decreasing, and thus ensuring that the aerosol has sufficient aroma reproduction and intensity, ensuring that the user has a better taste when inhaling the aerosol, which can significantly improve the user's inhalation experience.

[0044] Please refer to further details. Figure 2 , Figure 3 and Figure 4In some embodiments, the second guide channel 32 is a straight central channel directly opposite the vent 21, and the first guide channel 31 is an annular channel surrounding the central channel. In this embodiment, the second guide channel 32 is positioned centrally on the airflow divider 3, and the second guide channel 32 is a straight central channel directly opposite the vent 21, so that the air guided by the second guide channel 32 flows directly into the vent 21 of the atomizer 2, which facilitates the rapid flow of the aerosol-carrying airflow through the air guide channel 17 to the air outlet 16. Furthermore, the first guide channel 31 is arranged around the second guide channel 32 on the airflow divider 3, making the first guide channel 31 an annular channel surrounding the central channel, so that the air passing through the first guide channel 31 forms a dispersed airflow that blows in an annular pattern toward the mixing chamber 19, which can quickly and fully mix the airflow with the aerosol, improving the efficiency of the airflow carrying the aerosol. Furthermore, since the first guide channel 31 is an annular channel surrounding the central channel (second guide channel 32), the air guided by the second guide channel 32 flows directly into the vent 21 of the atomizing element 2. The airflow velocity in the second guide channel 32 is relatively higher than that in the first guide channel 31. According to Bernoulli's theorem, the pressure at the vent 21 of the atomizing element 2 is lower, which can guide the airflow in the annular channel (first guide channel 31) carrying aerosol particles to flow quickly towards the vent 21 of the atomizing element 2. This improves the efficiency of the airflow carrying aerosols and ensures that the airflow carrying aerosols is quickly guided to the outlet 16 through the air guide channel 17, significantly reducing aerosol losses on the wall, in bends, and in airflow stagnation areas. Understandably, to further reduce aerosol losses on the wall, in stepped surfaces, in bends, and in airflow stagnation areas, the air guide channel 17 is a straight channel with its central axis collinear with the central axis of the vent 21.

[0045] In some embodiments, the flow cross-sectional area of ​​the first guide channel 31 is larger than that of the second guide channel 32, ensuring that the airflow velocity of the second guide channel 32 is relatively higher than that of the first guide channel 31, which is beneficial to improving the efficiency of airflow carrying aerosols. Specifically, the ratio of the flow cross-sectional area of ​​the first guide channel 31 to that of the second guide channel 32 is (4-9):1, which can avoid aerosol retention and deposition above the vent 21 of the atomizing element 2 and also prevent aerosol retention and deposition in the mixing chamber 19. When the ratio of the flow cross-sectional area of ​​the first guide channel 31 to that of the second guide channel 32 is greater than 9:1, because the airflow rate guided by the second guide channel 32 is too small and the airflow rate guided by the first guide channel 31 is too large, aerosol retention and deposition are likely to occur above the vent 21 of the atomizing element 2. When the ratio of the flow cross-sectional area of ​​the first guide channel 31 to the flow cross-sectional area of ​​the second guide channel 32 is less than 4:1, the air flow rate guided by the second guide channel 32 is too large and the air flow rate guided by the first guide channel 31 is too small, which can easily lead to a large amount of aerosol retention and deposition in the mixing chamber 19.

[0046] Please refer to further details. Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 In some embodiments, the atomizing element 2 has an atomizing surface 22 on the side facing the airflow splitter 3. The atomized aerosol can be released into the mixing chamber 19 through the atomizing surface 22. The first guide channel 31 is an annular channel for blowing air towards the atomizing surface 22. In this embodiment, the atomizing surface 22 is provided on the side of the atomizing element 2 facing the airflow splitter 3, and the first guide channel 31 is an annular channel for guiding airflow towards the atomizing surface 22. This allows the air passing through the first guide channel 31 to form a dispersed airflow that blows annularly towards the atomizing surface 22, which can quickly, timely, and fully carry away the aerosol released on the atomizing surface 22, thus improving the efficiency of airflow carrying aerosol. Understandably, the atomizing surface 22 is an annular surface that matches the annular channel. The atomizing surface 22 is provided with a heating element for heating the atomized liquid and atomizing it to form an aerosol. The heating element can be, but is not limited to, a heating wire, heating plate, or heating film made of metal material.

[0047] Please refer to further details. Figure 2 and Figure 4 In some embodiments, the first guide channel 31 is an annular channel for blowing air towards the atomizing surface 22. The annular channel is inclined radially outward, so that the air passing through the first guide channel 31 forms a dispersed airflow that blows in an annular direction towards the atomizing surface 22. This can more quickly, timely and fully carry away the aerosols released on the atomizing surface 22, which is beneficial to improving the efficiency of airflow carrying aerosols.

[0048] Please refer to further details. Figure 1 , Figure 6 and Figure 7 In some embodiments, the atomizing surface 22 is an annular concave surface recessed on the atomizing element 2 and surrounding the vent 21, which facilitates the rapid convergence of the airflow carrying aerosol to the vent 21, and then the airflow is straight-lined into the guide channel through the vent 21, reducing the loss of aerosol on the wall, stepped surface, bend and airflow stagnation area.

[0049] Please refer to further details. Figure 2 , Figure 3 and Figure 4 In some embodiments, the airflow splitter 3 is provided with multiple branch channels 311, which are arranged in a ring to form an annular channel, and the annular channel surrounds the second guide channel 32. In this embodiment, the multiple branch channels 311 on the airflow splitter 3 are arranged in a ring to form an annular channel, so that the annular channel (first guide channel 31) surrounds the second guide channel 32. This facilitates the first guide channel 31 to guide the airflow toward the atomizing surface 22 for dispersion and purging, and can more quickly, timely and fully remove the aerosols released on the atomizing surface 22, thereby improving the efficiency of airflow in carrying aerosols.

[0050] Please refer to further details. Figure 2 , Figure 3 and Figure 4 In some embodiments, a nozzle 33 protrudes from the airflow splitter 3 at the outlet corresponding to the second guide channel 32 to prevent aerosol from accumulating and depositing at the outlet of the airflow splitter 3 at the outlet of the second guide channel 32. The nozzle 33's air outlet 34 is connected to the outlet of the second guide channel 32, and the nozzle 33's air outlet 34 is directly opposite the vent 21, so that the airflow ejected from the nozzle 33's air outlet 34 can directly enter the vent 21, improving the efficiency of airflow carrying aerosol.

[0051] Please refer to further details. Figure 2 In some embodiments, to further prevent aerosols from accumulating and depositing at the outlet of the second guide channel 32 of the airflow splitter 3, the end face of the nozzle 33 facing away from the airflow splitter 3 is configured as a hemispherical surface 35. It can be understood that, to further prevent aerosols from accumulating and depositing at the outlet of the second guide channel 32 of the airflow splitter 3, the end face of the nozzle 33 facing away from the airflow splitter 3 may also be configured as a frustoconical surface.

[0052] Please refer to further details. Figure 5 , Figure 6 and Figure 7In some embodiments, the atomizing element 2 is a porous ceramic heating element with micropores. A liquid storage tank 23 for storing atomizing liquid is provided on the side of the porous ceramic heating element away from the airflow diverter 3. The opening of the liquid storage tank 23 is connected to the liquid guide port 18. In this embodiment, a liquid storage tank 23 is provided on the side of the porous ceramic heating element facing the liquid guide port 18. As long as the opening of the liquid storage tank 23 is connected to the liquid guide port 18, the atomized liquid in the liquid storage chamber 14 can first flow out to the liquid storage tank 23 through the liquid guide port 18. The atomized liquid flowing out through the liquid guide port 18 can be temporarily stored in the liquid storage tank 23 of the porous ceramic heating element. On the one hand, this can avoid the formation of negative pressure in the liquid storage chamber 14 due to the consumption of atomized liquid in the liquid storage chamber 14, so that the atomized liquid can be smoothly, timely and stably transmitted to the atomization surface 22 of the porous ceramic heating element, and prevent the interruption of liquid supply. On the other hand, it can shorten the distance of the atomized liquid in the liquid storage chamber 14 to the atomization surface 22 of the porous ceramic heating element, so that the atomized liquid can be smoothly, timely and stably transmitted to the atomization surface 22 of the porous ceramic heating element, and ensure timely and sufficient liquid supply.

[0053] Please refer to further details. Figure 1 , Figure 2 and Figure 5 In some embodiments, the atomizing bullet body 1 includes a shell 11, an air guide pipe 12 disposed in the shell 11, and a base assembly 13 assembled in the bottom opening of the shell 11. The top of the shell 11 is provided with an air outlet 16. The pipe of the air guide pipe 12 forms an air guide channel 17 connecting the air outlet 16 and the air vent 21. The part of the shell 11 outside the air guide pipe 12 defines a liquid storage chamber 14. The base assembly 13 is provided with a liquid guide port 18 and an air inlet 15. The atomizing element 2 and the airflow diverting element 3 are disposed inside the base assembly 13. The base assembly 13 is provided with a mixing chamber 19. The air vent 21 of the atomizing element 2 connects the mixing chamber 19 and the air guide channel 17. When the atomizer is working, outside air is introduced into the first guide channel 31 and the second guide channel 32 on the airflow splitter 3 through the air inlet 15. A portion of the air is dispersed into the mixing chamber 19 through the first guide channel 31, and the aerosol in the mixing chamber 19 is quickly and fully carried to the vent 21 of the atomizer 2. At the same time, another portion of the air is gathered into the vent 21 through the second guide channel 32, and flows into the vent 21 with the air mixed with the aerosol. This allows the airflow carrying the aerosol to be quickly guided to the air outlet 16 through the air guide tube 12, which can significantly reduce the loss of aerosol on the wall, in bends and in the airflow stagnation area, thereby improving the efficiency of the airflow carrying the aerosol, preventing the aerosol concentration from decreasing, and thus ensuring that the aerosol has sufficient aroma reproduction and intensity, ensuring that the user has a better taste when inhaling the aerosol and improving the user's inhalation experience.

Figure 1In some embodiments, the base assembly 13 includes a sealing seat 131 fitted into the bottom opening of the housing 11, a support seat 132 supporting the airflow diverter 3, and an outer sleeve 133 fitted onto the housing 11. The sealing seat 131 has a positioning groove for positioning and installing the atomizing element 2. The atomizing element 2 is accommodated and installed in the positioning groove of the sealing seat 131. The positioning groove has a liquid guide port 18 communicating with the liquid storage chamber 14. The outer sleeve 133 has at least one air inlet 15. When the outer sleeve 133 has multiple air inlets 15, the multiple air inlets 15 are arranged at intervals along the circumference of the outer sleeve 133. It is understood that the sealing seat 131 may be, but is not limited to, a silicone part or a rubber part.

[0055] Please refer to further details. Figure 1 In some embodiments, the atomizer further includes a conductive rod 4 for electrically connecting the atomizing element 2 to the power supply device 5. The conductive rod 4 is mounted on the support base 132, and the airflow splitter 3 has a through hole 36 for the conductive rod 4 to pass through, with the conductive rod 4 inserted into the through hole 36. The power supply device 5 also has a conductive pin 6 for the conductive rod 4 to abut against the power supply device 5. The first end of the conductive rod 4 abuts against the conductive pin 6, and the second end of the conductive rod 4 abuts against the electrode on the atomizing element 2, thereby realizing the electrical connection between the atomizing element 2 and the power supply device 5.

[0056] Please refer to further details. Figure 1 In some embodiments, the atomizing element 2 is located below the liquid storage chamber 14, so that the atomizing liquid in the liquid storage chamber 14 can be completely consumed by the atomizing element 2, reducing the amount of atomizing liquid remaining in the liquid storage chamber 14. A sealing sleeve 7 is provided on the side of the atomizing element 2 where the liquid storage groove 23 is formed, and a sealing gasket 8 is provided between the atomizing element 2 and the support base to enhance the sealing performance and prevent leakage.
