Description

Technical Field

[0001] This application relates to the technical field of electronic atomization, and particularly relates to an electronic atomization device. Background Art

[0002] As an alternative to traditional cigarettes, an electronic atomization device generally includes a hollow shell, an atomization component disposed inside the shell, and a liquid storage cavity for supplying atomization liquid to the atomization component. The shell has a suction port, and the atomization component has an atomization cavity leading to the suction port. The atomization component is used to heat and atomize the atomization liquid supplied by the liquid storage cavity to form an inhalable aerosol leading to the suction port in the atomization cavity. Among them, a microphone (also known as an airflow sensor, pneumatic switch, etc.) for controlling the on / off of the heating function of the atomization component is usually disposed inside the above-mentioned shell. When the user sucks, the microphone can sense the airflow generated inside the shell due to the user's sucking to activate the heating function of the atomization component.

[0003] In the related art, in order to meet the user's demand for multiple flavors, an electronic atomization device with multiple independent liquid storage cavities is proposed. The multiple liquid storage cavities are used to store atomization liquids of different flavors. Among them, multiple groups of atomization components corresponding to the multiple liquid storage cavities one by one are disposed inside the shell of the electronic atomization device. In the above-mentioned electronic atomization device, the microphone is usually disposed in the area near the air inlet of the atomization component inside the shell, and the microphone is directly connected to the atomization cavity through the induction air passage, or the microphone is disposed on the side of the battery far from the atomization component, and the microphone is connected to the atomization cavity through the gap between the battery and the inner wall of the shell. For the former, in order to ensure that the negative pressure formed by the airflow generated when the user sucks can effectively act on the microphone, the microphone usually lacks effective protection measures, so that the condensate or leakage generated when the atomization component works is likely to flow to the microphone through the induction air passage, resulting in the microphone being unable to work properly. For the latter, the airflow path between the microphone and the atomization cavity is long and the airflow is too dispersed. Coupled with the blocking effect of the battery and other electronic components (such as a circuit board) on the airflow, the airflow will be attenuated, making it difficult for the microphone to sense the change of the airflow, resulting in the microphone being insensitive.

[0038] Referring to Figures 1 to 7 , the electronic atomization device according to an embodiment of the present application includes a housing 100, a first bracket 200, a microphone 300, and an atomization assembly.

[0039] Specifically, the housing 100 has a hollow internal structure. The first bracket 200 is disposed inside the housing 100. An induction cavity 210 and at least two intake channels 220 arranged side by side and extending longitudinally are provided on the first bracket 200. The induction cavity 210 and the intake channels 220 are arranged in a dislocation manner along a direction intersecting the longitudinal direction. A communication channel a is provided between the induction cavity 210 and each intake channel 220 so that the induction cavity 210 is respectively connected to each intake channel 220. The microphone 300 is disposed inside the induction cavity 210. The number of atomization assemblies is at least two groups. The atomization assemblies are disposed inside the housing 100 and at one end of the first bracket 200. Each atomization assembly is correspondingly connected to the outlet end of each intake channel 220. The intake end of the intake channel 220 (i.e., the end of the intake channel 220 away from the atomization assembly) is connected to the external atmosphere.

[0040] It should be noted that the above-mentioned longitudinal direction is the X direction in the drawings.

[0041] When the user sucks, an air flow can be formed from the microphone 300 to the atomization component, thereby forming a negative pressure acting on the microphone 300, and then triggering the microphone 300 to start the heating function of the atomization component. Among them, since the induction cavity 210 of the microphone 300 is connected to the air inlet channel 220 through the communication channel a, and the air outlet end of the air inlet channel 220 is connected to the atomization component, the air flow path between the microphone 300 and the atomization component is short and the air flow is relatively concentrated. Moreover, the air flow between the microphone 300 and the atomization component will not be blocked by the battery and other electronic components and attenuated, so that the microphone 300 can easily sense the change of the air flow, which is conducive to improving the sensitivity of the microphone 300. In addition, since the air inlet channel 220 with the air outlet end connected to the atomization component extends longitudinally, and the induction cavity 210 and the air inlet channel 220 are arranged in a staggered manner in a direction intersecting the longitudinal direction, it is conducive to reducing the situation where the condensate or leakage flows to the microphone 300.

[0042] It should be noted that in some of the embodiments, the communication channel a has a first end connected to the induction cavity 210 and a second end connected to the air inlet channel 220. Along the extension direction of the air inlet channel 220, the first end of the communication channel a is closer to the atomization component than the second end of the communication channel a. When the electronic atomization device is in use, it can make the first end of the communication channel a higher than the second end of the communication channel a, which is beneficial to increasing the difficulty of the condensate or leakage in the air inlet channel 220 entering the induction cavity 210, thereby further reducing the situation where the condensate or leakage flows to the microphone 300.

[0043] Refer to Figures 1 to 4 , in some of the embodiments, the induction cavity 210 has an opening for facilitating the assembly of the microphone 300. The electronic atomization device further includes a seal 400. The seal 400 is at least partially located between the outer wall of the microphone 300 and the inner wall of the induction cavity 210. At least part of the communication channel a is formed between the outer wall of the seal 400 and the inner wall of the induction cavity 210. By providing the seal 400, it is beneficial to prevent the condensate or leakage from flowing to the microphone 300.

[0044] Refer to Figure 1 and Figure 2, in some of these embodiments, the induction cavity 210 is disposed at one end of the first bracket 200 away from the atomization assembly. A transverse groove 230 is provided at the end of the first bracket 200 away from the atomization assembly. A longitudinal groove 240 is provided on the inner sidewall of the induction cavity 210. One end of the transverse groove 230 communicates with the air inlet passage 220, and the other end of the transverse groove 230 communicates with the longitudinal groove 240. The seal 400 is disposed at the end of the first bracket 200 away from the atomization assembly and covers the transverse groove 230 and the longitudinal groove 240 to enclose and form the above-mentioned communication passage a. The communication passage a is formed by the mutual cooperation of the first bracket 200 and the seal 400, which is beneficial to reducing the processing difficulty compared with the case where the communication passage a is formed in an integral structure.

[0045] Referring to Figure 5 and Figure 6 , in some of these embodiments, an exhaust groove 250 communicating with the external atmosphere is provided on the inner sidewall of the induction cavity 210. During the process of installing the microphone 300 in the induction cavity 210, the exhaust groove 250 can discharge the air in the induction cavity 210, which is beneficial to preventing the diaphragm of the microphone 300 from being deformed and damaged due to excessive air pressure inside the induction cavity 210.

[0046] It should be noted that, in some of these embodiments, the cross-sectional dimension of the exhaust groove 250 is smaller than that of the communication passage a, so that the maximum air flow rate per unit time of the exhaust groove 250 is less than the maximum air flow rate per unit time of the communication passage a. When the user sucks, a negative pressure acting on the microphone 300 can be stably formed, which is beneficial to reducing the influence of the exhaust groove 250 on the sensitivity of the microphone 300.

[0047] It should be noted that, in some of these embodiments, the air inlet end of the air inlet passage 220 has an air inlet 221, and the cross-sectional dimension of the air inlet 221 is larger than that of the communication passage a, so that the maximum air flow rate per unit time of the air inlet 221 is greater than the maximum air flow rate per unit time of the communication passage a. When the user sucks, it is beneficial to reduce the air intake resistance of the air inlet passage 220, which is beneficial to ensuring the air intake volume of the air inlet passage 220.

[0048] Referring to Figure 1 , in some of these embodiments, the electronic atomization device further includes an oil cup 500 disposed in the housing 100. At least two liquid storage cavities 510 are provided inside the oil cup 500, and each liquid storage cavity 510 communicates with each atomization assembly one by one. Its structure is simple and easy to implement, which is beneficial to reducing the processing difficulty of the housing 100.

[0049] It should be noted that, in some other embodiments, the liquid storage cavity 510 can also be independently formed in the housing 100. In this case, the above-mentioned oil cup 500 does not need to be provided, and this is not limited herein.

[0050] Referring toFigure 1 and Figure 2 In some embodiments, the electronic atomization device further includes at least two second brackets 600 corresponding to each atomization component one by one. The liquid storage cavity 510 has an opening, the second brackets 600 are arranged at the opening of the liquid storage cavity 510, one end of the first bracket 200 close to the atomization component has a supporting portion 260, and the atomization component is arranged between the second bracket 600 and the supporting portion 260, that is, the atomization component is fixed by the second bracket 600 and the supporting portion 260, and its structure is simple and easy to implement.

[0051] Referring to Figure 1 、 Figure 2 and Figure 7 In some embodiments, the atomization component includes an oil guiding body 710, a heating body 720, an air passage member 730, and an electrode post 740 for accessing a power source. The oil guiding body 710 has an absorption surface and an atomization surface arranged oppositely. The heating body 720 is arranged on the atomization surface of the oil guiding body 710. One side of the air passage member 730 is provided with a diversion groove 731 with two open ends. The diversion groove 731 and the atomization surface of the oil guiding body 710 enclose an atomization cavity b communicating with the air outlet end of the air intake passage 220. The second bracket 600 is provided with an oil inlet hole 610 for fluidly connecting the liquid storage cavity 510 and the absorption surface of the oil guiding body 710. The electrode post 740 penetrates through the supporting portion 260 and is electrically connected to the heating body 720. When the user sucks, an air flow is formed from the microphone 300 to the atomization cavity b, thereby forming a negative pressure acting on the microphone 300, and then triggering the microphone 300 to start the heating body 720 to heat and atomize the atomization liquid flowing to the atomization surface of the oil guiding body 710, and finally forming an inhalable aerosol in the atomization cavity b.

[0052] Referring to Figure 1 In some embodiments, the housing 100 has a suction port 110 for the user to suck. At least two air outlet channels 520 corresponding to each atomization cavity b one by one are arranged inside the oil cup 500. The air inlet end of the air outlet channel 520 communicates with the atomization cavity b, and the air outlet end of the air outlet channel 520 communicates with the suction port 110. When the user sucks, the inhalable aerosol formed in the atomization cavity b flows to the suction port 110 through the air outlet channel 520 for the user to inhale.
