[0029] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0030] like Figures 1 to 5As shown, an embodiment of the present application provides an atomization device, which mainly includes an oil cup 2, a base 3 and a microphone 4. The oil cup 2 is provided with an oil tank 21 and an atomizer core 6 connected to the liquid in the oil tank 21; the base 3 is arranged at the end of the oil cup away from the oil tank, and encloses an atomizer chamber 5 with the oil cup 2 and the atomizer core 6. The atomizer chamber 5 is provided with an atomizer core 6 for atomizing the tobacco oil in the oil cup 2, and the base 3 can provide support for the atomizer core 6. Among them, the side of the base 3 facing away from the atomizer chamber 5 is provided with a sensing chamber 31 and an annular airway 32 located around the sensing chamber 31. That is, the side of the base 3 facing away from the atomizer chamber 5 is provided with a sensing chamber 31 and an annular airway 32, and the annular airway 32 is provided on the circumferential outside of the sensing chamber 31. In addition, the base 3 is provided with a first connecting channel 33 connecting the atomizing chamber 5 and the annular air channel 32 and a second connecting channel 34 connecting the sensing chamber 31 and the annular air channel 32. That is, the first connecting channel 33 connects the atomizing chamber 5 and the annular air channel 32, and the first connecting channel 33 connects the sensing chamber 31 and the annular air channel 32.

[0031] Furthermore, the air inlet ends of the first connecting channel 33 and the second connecting channel 34 are staggered in the circumferential direction of the annular air passage 32, and the microphone 4 is disposed within the sensing chamber 31. In other words, the first connecting channel 33 and the second connecting channel 34 are not connected, which increases the distance the atomized gas travels from the atomizing chamber 5 to the sensing chamber 31. This reduces the probability that smoke atomized in the atomizing chamber 5, or condensed liquid or leaked liquid formed by the smoke, will flow into the sensing chamber 31, thereby reducing the probability that the microphone 4 will be blocked by condensed liquid or leaked liquid formed by the smoke, thereby ensuring the normal operation of the microphone 4.

[0032] In the atomizing device of the above structure, the base 3 and the oil cup 2 enclose an atomizing chamber 5, a sensing chamber 31 and an annular air passage 32 located on the peripheral side of the sensing chamber 31 are provided on the side of the base 3 facing away from the atomizing chamber 5, a first connecting passage 33 connecting the atomizing chamber 5 and the annular air passage 32 and a second connecting passage 34 connecting the sensing chamber 31 and the annular air passage 32 are provided on the base 3, wherein the microphone 4 is arranged in the sensing chamber 31, so as to reduce the flow of atomized flue gas to the sensing chamber 31 where the microphone 4 is located, thereby preventing condensation or leakage from blocking the microphone 4. Moreover, it is ensured that the air inlet ends of the first connecting passage 33 and the second connecting passage 34 are staggered in the circumferential direction of the annular air passage 32, so as to further reduce the flow of atomized flue gas and coolant to the position of the microphone 4 in the sensing chamber 31, and even prevent flue gas, condensation or leakage from flowing to the microphone 4, thereby preventing condensation or leakage from blocking the microphone 4, so that the microphone 4 can normally control the start and stop of the atomizing device.

[0033] In some embodiments, the atomization device also includes a shell 1 and a power supply. The base 3 and the power supply are located inside the shell 1. The oil cup 2 is detachably connected to the shell 1. The shell 1 provides installation space for the base 3 and the oil cup 2. The shell 1 is also convenient for the user to hold.

[0034] In some embodiments, in the axial direction of the oil cup 2, the distance between the air inlet end of the second connecting channel 34 and the oil cup 2 is greater than the distance between the air inlet end of the first connecting channel 33 and the oil tank 21. Figure 2 When placed vertically in the direction shown, the height of the air inlet end of the second connecting channel 34 is higher than the height of the air inlet end of the first connecting channel 33. In this way, after the atomizer core 6 in the atomizer chamber 5 atomizes the e-liquid in the oil cup 2, due to the above-mentioned height difference between the inlet ends of the first connecting channel 33 and the second connecting channel 34, and the staggered arrangement of the inlet ends of the first connecting channel 33 and the second connecting channel 34, the atomized smoke, condensate or leakage in the atomizer chamber 5 is further prevented from flowing into the atomizer chamber 5, thereby further preventing the condensate or leakage from blocking the microphone 4.

[0035] It should be noted that the axial direction of the oil cup 2 refers to Figure 2 The Y-axis shown in .

[0036] Based on the above embodiment, further, the first connecting channel 33 extends on the base 3 along the axial direction of the oil cup 2 and penetrates the base 3, and / or the second connecting channel 34 extends on the base 3 along the radial direction of the oil cup 2. Specifically, on the basis of ensuring that the inlet ends of the first connecting channel 33 and the second connecting channel 34 are staggered, the first connecting channel 33 and the second connecting channel 34 are arranged in the above manner. This can further increase the path length between the atomizing chamber 5 and the sensing chamber 31, thereby preventing atomized smoke, condensed liquid, or leaked liquid in the atomizing chamber 5 from flowing into the sensing chamber 31, thereby preventing the condensed liquid or leaked liquid from clogging the microphone 4.

[0037] For example, the axial direction of the housing 1 refers to Figure 2 The Y axis shown in FIG, the radial direction of the housing 1 refers to Figure 2 The X-axis shown in .

[0038] Of course, the first connecting channel 33 and the second connecting channel 34 can also be arranged in other ways. For example, there is an acute angle between the first connecting channel 33 and the axial direction of the shell 1, and / or there is an acute angle between the second connecting channel 34 and the radial direction of the shell 1.

[0039] In some embodiments, the end of the base 3 away from the atomizing chamber 5 is further provided with an end cap 37, and the end cap 37 is provided with an air inlet 35 connecting the annular airway 32 and the external atmosphere, and the air inlet 35 is staggered with the first connecting channel 33 and the second connecting channel 34. That is to say, in the axial direction of the oil cup 2, the air inlet 35 does not overlap with the first connecting channel 33 and the second connecting channel 34. In this way, when the user inhales through the suction nozzle 7, the external gas will enter the shell 1 of the atomizing chamber 5, and then the gas will enter the annular airway 32 through the air inlet 35 of the annular airway 32. Since the air inlet 35 is staggered with the first connecting channel 33 and the second connecting channel 34, the gas entering the annular airway 32 can be prevented from directly entering the first connecting channel 33 and the second connecting channel 34, and the gas can be dispersed in the annular airway 32. Moreover, when multiple first connecting channels 33 are set between the annular air channel 32 and the atomization chamber 5, the above-mentioned arrangement can further prevent the gas flowing into the annular air channel 32 through the air inlet hole 35 from flowing into the atomization chamber 5 through a certain first connecting channel 33. In this way, the gas can be more evenly dispersed and flowed to different areas of the atomization chamber 5 through the multiple first connecting channels 33 to ensure the smoke content in the gas sucked out by the suction nozzle 7.

[0040] In some embodiments, the second connecting channel 34 extends through the sidewall of the base 3 on the side facing away from the sensing chamber 31, and the inner wall of the oil cup 2 blocks the opening of the second connecting channel 34 in the sidewall. In other words, the second connecting channel 34 extends directly from the sidewall of the base 3 into the sensing chamber 31, and the oil cup 2 then blocks the opening of the second connecting channel 34 in the sidewall of the base 3. This arrangement ensures that gas within the annular airway 32 does not diffuse to other locations in the atomizer. Compared to a system where the second connecting channel 34 only connects the sensing chamber 31 and the annular airway 32, it reduces the difficulty of slotting the second connecting channel 34 and reduces the manufacturing cost of the base 3.

[0041] Of course, the side of the second connecting channel 34 away from the sensing chamber 31 may not pass through the side wall of the base 3, and the first connecting channel 33 is only provided between the annular channel and the sensing chamber 31, so that the communication between the annular channel and the sensing chamber 31 can also be achieved.

[0042] Furthermore, based on the above embodiment, the sidewalls of the base 3 are further provided with sealing ribs 36 located outside the opening. These ribs 36 are designed to seal against the inner wall of the oil cup 2, thereby sealing the gap between the base and the inner wall of the oil cup 2. It should be noted that the number and arrangement of these ribs 36 are not limited herein. For example, the ribs 36 may be one circumferentially disposed around the opening; two ribs 36 may be disposed circumferentially around the base 3 and located on either side of the opening; or multiple ribs 36 may be disposed circumferentially around the base 3 and located on either side of the opening. This arrangement isolates the sealed cavity connecting the annular airway 32 and the sensing cavity 31 from the space outside the base 3, thereby improving the airtightness of the contact between the base 3 and the oil cup 2. The interference fit between the ribs 36 and the oil cup 2 prevents air leakage from affecting the suction resistance and improves the sensitivity of the microphone 4 during activation.

[0043] In some embodiments, the oil cup 2 includes multiple oil tanks 21 arranged along the circumference or radial direction of the oil cup 1, and the atomizer core 6 is provided in multiple positions, and is arranged one-to-one with the oil tank 21. Exemplarily, the atomizer core 6 has a liquid suction surface connected to the liquid in the oil tank 21, and an atomizing surface facing the atomizing chamber 5, wherein the liquid suction surface and the atomizing surface are arranged opposite to each other. The atomizer core 6 can include a porous material, such as porous ceramics, porous glass or porous metal. Specifically, the atomizer core 6 can include an oil guide body made of a porous material and a heating element arranged on the oil guide body.

[0044] Specifically, the provision of multiple oil reservoirs 21 ensures a consistent supply of oil when the atomizer atomizes the liquid. By providing multiple atomizer cores 6 to simultaneously heat the oil within the multiple oil reservoirs 21, the atomization effect of the oil can be enhanced, the amount of smoke generated can be increased, and thus the atomization efficiency of the atomizer. Furthermore, a mounting groove for the atomizer cores 6 is provided on the bottom wall of the oil reservoir 21, opposite the base 3. This allows the base 3 to provide support for the atomizer cores 6. This ensures the stability of the atomizer cores 6, preventing them from shifting when the atomizer is shaken, thereby preventing leakage of liquid from the oil reservoir 21.

[0045] In some embodiments, the base is provided with a plurality of first connecting channels, each of which corresponds to a one-to-one correspondence with an atomizer core. The airflow entering through each first connecting channel 33 can more quickly carry away the smoke atomized from each oil tank 21, thereby improving the efficiency of the airflow in carrying away the smoke, thereby enhancing the user experience when using the atomizer device.

[0046] In some embodiments, the atomization device further includes a seal 9 for sealing multiple atomization cores 6. It should be noted that the number of seals 9 provided is not limited herein; one or more seals 9 may be provided. In other words, one seal 9 may seal multiple atomization cores 6, or one seal 9 may seal a single atomization core 6. When the seal 9 simultaneously seals multiple atomization cores 6, this can improve the convenience of assembling the seal 9 with the multiple atomization cores 6, enhance the installation efficiency of the atomization device, facilitate subsequent maintenance and replacement of the seal 9, and enhance the airtightness after the seal 9 is installed.

[0047] In some embodiments, a suction nozzle 7 is provided at one end of the oil cup 2 away from the base 3, and the oil cup 2 defines a third connecting channel 22 connecting the suction nozzle 7 and the atomizing chamber 5. Specifically, when a user uses the atomizing device, the user inhales through the suction nozzle 7, and the gas outside the atomizing device enters the atomizing device through the air inlet component provided in the atomizing device. The airflow then enters the annular airway 32 through the air inlet hole 35 provided on the base 3, and then the airflow respectively enters the atomizing chamber 5 through the multiple first connecting channels 33. At the same time, the microphone 4 in the sensing chamber 31, which is connected to the annular airway 32 through the second connecting channel 34, controls the operation of the atomizing core according to the received gas pressure. The multiple atomizing cores simultaneously atomize the e-liquid in the multiple oil tanks 21. The gas flowing from the multiple first connecting channels 33 to the atomizing chamber 5 converges in the atomizing chamber 5. The airflow then carries the atomized smoke through the third connecting channel 22 to the suction nozzle 7 and is finally inhaled by the user.

[0048] In some embodiments, multiple oil tanks 21 are arranged around the circumferential outside of the third connecting channel 22. That is, multiple oil tanks 21 are arranged along the circumference of the atomizer device, and the air guide channel is arranged between the multiple oil tanks 21. With this arrangement, the multiple atomizer cores 6 atomize the smoke oil flowing out of the multiple oil tanks 21 one-on-one, and the air guide channel can better guide the smoke oil produced by the multiple atomizer cores 6, thereby improving the efficiency of guiding the smoke gas after the smoke oil is atomized. Moreover, the rationality of the layout of the oil tank 21 and the air guide channel can be improved, which can increase the volume of the oil tank 21, thereby increasing the volume of the smoke oil stored in the oil tank 21 and improving the battery life of the atomizer device.

[0049] In some embodiments, the base 3 and the side facing the atomization chamber 5 are further provided with a liquid collecting tank 8 opposite to the third connecting channel 22. Specifically, the side surface of the base 3 forming the atomization chamber 5 is a concave side surface, and a liquid collecting tank 8 for storing condensate is formed on this side surface. During the operation of the atomization device, the atomization core 6 atomizes the smoke oil into smoke through high temperature. The smoke will condense into condensate when it encounters cold during the flow process. By providing the liquid collecting tank 8 on the side of the base 3 forming the atomization chamber 5, the storage of the condensate can be conveniently realized, and the condensate can be prevented from adhering to other components of the atomization device. In addition, such a configuration can also facilitate the recovery and cleaning of the condensate, prevent the condensate oil from clogging or corroding the components in the atomization device, and improve the service life of the atomization device.

[0050] In some embodiments, the first connecting channel 33 is a tapered air channel that gradually converges from the annular air channel 32 toward the atomizing chamber 5. Specifically, during the process of atomizing the e-liquid by the atomizing device, the gas flows from the annular air channel 32 to the atomizing chamber 5 through the first connecting channel 33. Setting the first connecting channel 33 as a tapered air channel can facilitate the circulation of gas and improve the efficiency of the flow from the annular air channel 32 to the atomizing chamber 5. Moreover, the tapering direction of the first connecting channel 33 is from the annular air channel 32 to the atomizing chamber 5. This can increase the resistance of the smoke in the atomizing chamber 5 to flow back to the annular air channel 32 through the first connecting channel 33, thereby preventing the atomized smoke in the atomizing chamber 5 from flowing back to the annular air channel 32 to a certain extent, thereby further preventing the smoke from flowing toward the sensing chamber 31, and further preventing the condensate after the smoke is cooled from blocking the microphone 4 located in the sensing chamber 31, so that the microphone 4 can normally control the start and stop of the atomizing device.
