In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0027] Example:

[0028] like Figure 1-6 As shown, in this embodiment, the electronic atomization device includes an atomizer 2 and a power supply device, wherein the power supply device is connected to the atomizer 2, an atomization channel 2a is formed in the atomizer 2, and the air inlet 11a is connected to the atomization channel 2a.

[0029] Specifically, the power supply device can supply power to the atomizer 2, and the side wall of the atomization channel 2a can be provided with a heating sheet 21 for conductive connection with the power supply device. After power is turned on, the heating sheet 21 can heat the stored atomization liquid to generate aerosol, and the generated aerosol can be discharged along the atomization channel 2a to the outside of the atomizer 2 for the user to inhale.

[0030] In this embodiment, the power supply device includes: a main body 1 with an air inlet hole 11a formed therein, the air inlet hole 11a is used to communicate with the atomization channel 2a of the atomizer 2, the main body 1 also includes a first oil absorption member 113 and a ventilation member 111 provided with a microphone hole 11c; the axis of the air inlet hole 11a intersects with the axis of the microphone hole 11c, and an air passage cavity 11b for gas circulation is formed between the air inlet hole 11a and the microphone hole 11c; a flange 1111 is provided at one end of the microphone hole 11c facing the air passage cavity 11b.

[0031] Specifically, the microphone hole 11c and the air inlet hole 11a can be inclined at a certain angle, or can be perpendicular to each other. Preferably, the axis of the microphone hole 11c and the axis of the air inlet hole 11a are perpendicular to each other, and the axis of the air inlet hole 11a is parallel to the longitudinal axis of the power supply device; an air cavity 11b is provided between the air inlet hole 11a and the microphone hole 11c, that is, the air inlet hole 11a and the microphone hole 11c are not directly connected, and the air inlet hole 11a and the microphone hole 11c are not directly opposite, when the smoke oil accidentally leaks to the air inlet hole 11a along the atomization channel 2a, the leaked smoke oil will not directly enter the microphone hole 11c, thereby effectively preventing the smoke oil from entering the microphone hole 11c and entering other parts of the atomizer along the microphone hole 11c to affect the use function of related components, and the anti-leakage effect is good. The flange 1111 is located in the air cavity 11b, and the flange 1111 can be an annular flange integrally connected to the vent 111. Due to the presence of the flange 1111, even if the leaked liquid enters the air cavity 11b, it is difficult to directly enter the microphone hole 11c, thereby further improving the anti-leakage effect of the electronic atomization device.

[0032] In this embodiment, a first oil-absorbing member 113 is arranged in the air passage cavity 11b, and the lowest side of the microphone head hole 11c in the height direction is higher than the lowest side of the first oil-absorbing member 113. The first oil-absorbing member 113 defines an air flow channel between a portion of the air passage cavity 11b and the microphone air inlet hole 11a and the head hole 11c, respectively, so that the smoke oil leaking from the air inlet hole 11a can be preferentially and quickly absorbed by the first oil-absorbing member 113, thereby effectively preventing the smoke oil from entering the microphone head hole 11c and entering other parts of the atomizer along the microphone head hole 11c to affect the use functions of related components, and having a good anti-leakage effect.

[0033] In this embodiment, the first oil-absorbing member 113 is wrapped around the outer peripheral side of the flange 1111, so that the smoke oil can be directly absorbed by the first oil-absorbing member 113 regardless of whether it reaches the upper side of the flange 1111 or the lower side of the flange 1111 first, so as to prevent the smoke oil from entering the microphone hole 11c. Further, in this embodiment, the end of the flange 1111 close to the air cavity 11b deviates from the bottom of the air inlet hole 11a, so that the distance from the bottom end of the air inlet hole 11a to the entrance of the microphone hole 11c is increased, so that the leaked smoke oil can be fully absorbed by the first oil-absorbing member 113 in the air cavity 11b, further improving the anti-leakage effect of the electronic atomization device.

[0034] In this embodiment, the end of the ventilator 111 away from the first oil-absorbing member 113 is also connected to the second oil-absorbing member 114, and the main body 1 further includes a microphone 13 disposed on the side of the second oil-absorbing member 114 away from the ventilator 111, the microphone 13 and the second oil-absorbing member 114 are spaced apart from each other, and the second oil-absorbing member 114 is provided with a clearance port 114a for gas to flow between the microphone hole 11c and the microphone 13. Specifically, a mounting cavity is provided in the main body 1, and the mounting cavity is located on the side of the ventilator 111 away from the air cavity 11b, the second oil-absorbing member 114 and the microphone 13 are both fixed in the mounting cavity, and the second oil-absorbing member 114 and the microphone 13 are spaced apart from each other; the second oil-absorbing member 114 is located between the microphone 13 and the microphone hole 11c, and the second oil-absorbing member 114 is provided with a clearance port 114a for gas to flow between the microphone hole 11c and the microphone 13. When the leaked smoke oil accidentally enters the microphone hole 11c and passes through the microphone hole 11c, the second oil absorption member 114 can absorb it, thereby preventing the smoke oil from reaching the microphone 13, reducing the risk of damage to the microphone 13. The second oil absorption member 114 is provided with a clearance port 114a for gas to flow between the microphone hole 11c and the microphone 13, so that an air intake auxiliary air path is formed between the microphone hole 11c and the microphone 13, and when the user inhales, the microphone 13 is driven to start.

[0035] like Figure 2-4As shown, in the first implementation of the present embodiment, a side of the vent 111 away from the air cavity 11b is further connected to a blocking shell 112 directly opposite to the microphone hole 11c, the blocking shell 112 is located in the clearance port 114a, and a guide groove 1121 is formed in the blocking shell 112, and the guide groove 1121 is used to guide the smoke oil leaking from the microphone hole 11c to flow to the second oil suction member 114. The setting of the blocking shell 112 can prevent the smoke oil from flowing directly to the microphone 13, and the guiding effect of the guide groove 1121 can guide the smoke oil leaking from the microphone hole 11c to the second oil suction member 114, so that it is absorbed by the second oil suction member 114, reducing the risk of the smoke oil flowing to the microphone 13 and causing the microphone 13 to short-circuit. Furthermore, an L-shaped channel is formed between the guide groove 1121 and the microphone hole 11c for gas to flow between the microphone hole 11c and the microphone 13. Specifically, the guide groove 1121 is perpendicular to the microphone hole 11c and extends downward. There is a space for gas to flow between the lower end of the guide groove 1121 and the microphone 13, and the lowest side of the microphone 13 is higher than the lowest side of the second oil suction member 114. External gas can pass through the microphone hole 11c and the L-shaped channel in sequence and then reach the microphone 13, and be detected by the microphone 13; the accidentally leaked smoke oil will first be blocked by the blocking shell 112 after passing through the microphone hole 11c, and then flow downward along the guide groove 1121, and then be absorbed by the second oil suction member 114. The L-shaped channel is set in this way, which is not only simple in structure, but also conducive to further improving the anti-leakage effect of the atomizer.

[0036] like Figure 5 and 6 As shown, in the second implementation of the present embodiment, a transition chamber 11d is formed in the main body 1, which is at least partially opposite to the air inlet 11a, and a third oil suction member 115 is arranged in the transition chamber 11d. A gas flow channel connecting the air inlet 11a and the air passage 11b is formed in the transition chamber 11d. Specifically, one or more abutting parts can be arranged in the transition chamber 11d to lift up the third oil suction member 115 and abut and fix the third oil suction member 115, and sufficient space is reserved in the transition chamber 11d for gas circulation. The third oil suction member 115 can be deviated from the right below the air inlet 11a. Of course, the third oil suction member 115 can also be located right below the air inlet 11a, as long as it is ensured that sufficient space is reserved in the transition chamber 11d for gas to flow between the air inlet 11a and the air passage 11b, and no limitation is made here. The third oil-absorbing member 115 defines an air flow channel in which at least part of the transition cavity 11d is connected to the air inlet hole 11a and the air passage cavity 11b respectively, so that when the smoke oil accidentally leaks into the air inlet hole 11a, it can be preferentially absorbed by the third oil-absorbing member 115, thereby reducing the possibility of the smoke oil leaking into the microphone hole 11c, thereby improving the anti-leakage effect of the electronic atomization device.

[0037] In this embodiment, the main body 1 includes a fixing frame 11 and a shell 12 sealed and connected to the outside of the fixing frame 11, and the air inlet 11a, the vent 111, and the microphone hole 11c are all formed in the fixing frame 11, and the fixing frame 11 and the shell 12 are enclosed to form an air cavity 11b. Specifically, the sealing connection between the fixing frame 11 and the shell 12 can prevent the leaked smoke oil from leaking out from the connection between the fixing frame 11 and the shell 12 after reaching the air cavity 11b. It can be understood that in some other embodiments, the air cavity 11b can also be formed as a whole in the fixing frame 11, which is not limited here. Further, a receiving groove connecting the air inlet 11a and the microphone hole 11c is provided in the fixing frame 11, and a sealing bone position 1162 is provided at the edge of the groove of the receiving groove, and the sealing bone position 1162 is sealed and connected to the inner wall of the shell 12 to form the air cavity 11b. Specifically, an annular sealing bone 1162 may be provided at the edge of the notch of the receiving groove. When the fixing frame 11 is installed in the shell 12, the sealing bone 1162 may be in airtight contact with the inner wall of the shell 12, thereby preventing the smoke oil from leaking from the connection between the notch of the receiving groove and the inner wall of the shell 12. In some specific embodiments, an annular groove matching the shape of the sealing bone 1162 may be provided on the inner wall of the shell 12, so that when the fixing frame 11 is installed in the shell 12, the sealing bone 1162 is fixed with the annular groove by interference fit, and the sealing effect is good.

[0038] In this embodiment, a groove 1161 is provided on the outside of the fixing frame 11, and the groove 1161 and the inner wall of the shell 12 are enclosed to form an airflow channel 1a connecting the air cavity 11b and the outside. The formed airflow channel 1a deviates from the bottom of the air inlet 11a. When the user inhales, the external gas can directly enter the air cavity 11b along the airflow channel 1a and then pass through the air inlet 11a to reach the atomization channel 2a. That is, when the user inhales, the smoke does not flow through the battery core and other parts of the atomizer 2, which is conducive to improving the purity of the smoke and reducing the odor, thereby improving the user's smoking experience. Further, in this embodiment, the main body 1 also includes a battery assembly 14, and the fixing frame 11 is provided with a leakproof wall 116 forming a groove 1161, and the battery assembly 14 is fixed to the side of the leakproof wall 116 away from the groove 1161. The leakproof wall 116 can completely separate the battery assembly 14 from the airflow channel 1a, so as to prevent the smoke oil from leaking into the battery assembly 14 and damaging it.

[0039] In this embodiment, the electronic atomization device includes an atomizer 2 movably mounted on the top side of a fixing frame 11, and an atomization channel 2a is formed in the atomizer 2. The power supply device also includes an electrode 15 fixed at one end on the fixing frame 11, a connecting tube 117 is provided on the top of the fixing frame 11, an air inlet 11a passes through the connecting tube 117, and a diaphragm corresponding to the position of the connecting tube 117 and the electrode 15 is provided on the bottom side of the atomizer 2; when the electronic atomization device is not activated, the electrode 15 and the connecting tube 117 are separated from the atomization channel 2a; when the electronic atomization device is activated, the fixing frame 11 can be moved toward the atomizer 2 under the action of an external force, and during the movement, the connecting tube 117 and the electrode 15 can pierce the corresponding diaphragm and enter the atomizer 2, so that the air inlet 11a and the atomization channel 2a are connected, and the electrode 15 and the heating sheet 21 of the atomizer 2 are conductively connected. Specifically, when not activated, the atomizer 2 and the fixing frame 11 are first set to a semi-assembled state, and the bottom of the atomizer 2 is sealed by a diaphragm, that is, the atomization channel 2a and the air inlet 11a are separated by the diaphragm, which can prevent the smoke oil from leaking into the air inlet 11a along the atomization channel 2a, and effectively prevent the smoke oil from leaking from the bottom of the atomizer 2 during transportation. When it is necessary to activate, the connecting tube 117 and the electrode 15 are respectively pierced through the corresponding diaphragms to enter the atomizer 2, so that the air inlet 11a and the atomization channel 2a are connected, and the electrode 15 and the heating sheet 21 of the atomizer 2 are conductively connected, thereby obtaining a fully assembled electronic atomization device, which is simple to operate and convenient for users to experience smoking.

[0040] Further, in this embodiment, the outer peripheral side of the atomizer 2 is provided with a first buckle groove and a second buckle groove arranged in sequence along the insertion direction of the connecting tube 117 during the assembly operation, and the inner wall of the shell 12 is provided with a buckle; when the electronic atomization device is not activated, the buckle is buckled and connected with the first buckle groove, at this time, the electrode 15 and the connecting tube 117 are separated from the atomization channel 2a; when the electronic atomization device is activated, the shell 12 and the fixing frame 11 are moved toward the atomizer 2 as a whole under the action of external force until the buckle is buckled and fixed with the second buckle groove. In this way, through the arrangement of the buckle of the shell 12 and the first buckle groove, the second buckle groove and other structures, the atomizer 2, the fixing frame 11 and the shell 12 are initially fixed and the position alignment is completed when shipped. When it is necessary to activate, it is only necessary to apply force to bring the shell 12 and the atomizer 2 closer to each other until the buckle is snapped into the second buckle groove. There is no need for the user to specifically control the atomizer 2 to align with the power supply device. The operation is simple, easy to use, and the leak-proof effect is good.
