Description

Technical Field

[0001] The utility model relates to the technical field of atomization, in particular to an atomization device. Background Art

[0002] The smoke from burning cigarettes contains harmful substances such as tar, and long-term inhalation of these harmful substances will cause great harm to the human body. In order to overcome the harmful substances produced by burning cigarettes, a series of atomization devices have emerged.

[0003] A conventional atomizer device has an airflow channel and an airflow sensing element disposed therein. The airflow sensing element can drive the atomizer assembly in the atomizer device to start working when sensing airflow changes in the airflow channel. However, when the conventional atomizer device is not in use, such as during transportation or when the user does not inhale and is temporarily shelved, the influence of the external environment can easily cause the airflow / air pressure in the airflow channel to change, causing the airflow sensing element to be triggered by mistake and then causing the atomizer assembly to start by mistake, which not only wastes the atomizer matrix and unnecessary electricity, but also a heating element is usually disposed in the atomizer assembly, which may also cause safety problems.

[0004] BACKGROUND OF THE PRESENT APPLICATION The above information disclosed is only used to understand the background of the concept of the present application, and does not indicate or imply that it contains information of the prior art. Utility Model Content

[0005] Based on this, it is necessary to provide an atomization device to address the above problems.

[0006] An atomizing device, comprising:

[0007] A shell, wherein a top end of the shell is provided with an air outlet;

[0008] An atomizing assembly, wherein the atomizing assembly is disposed in the housing and an atomizing chamber is formed in the atomizing assembly, the atomizing chamber is used to generate aerosol and one end of the atomizing chamber is connected to the air outlet;

[0009] An airflow sensing component, the airflow sensing component is disposed in the housing and electrically connected to the atomizing component, one side of the airflow sensing component is communicated with the air outlet, and the airflow sensing component is used to drive the atomizing component to work when sensing airflow changes;

[0010] A bottom cover, the bottom cover is arranged at the bottom end of the shell and is provided with a first sensing hole and a first air inlet hole, the first sensing hole is communicated with the other side of the airflow sensing component, and the first air inlet hole is communicated with the other end of the atomization chamber; and

[0011] A switch structure, wherein a second sensing hole, a second air inlet hole and an opening are provided on the switch structure, and the switch structure is arranged on the bottom cover and can be rotated to a first position and a second position relative to the bottom cover; when in the first position, the switch structure blocks the first air inlet hole, and the first sensing hole is connected with the second sensing hole; when in the second position, the first air inlet hole is connected with the second air inlet hole, and the opening is connected with the first sensing hole.

[0012] The above-mentioned atomizer device can at least achieve the following beneficial effects: when the atomizer device is not in use, such as when the atomizer device is to be packaged for transportation, charged or placed idle, the switch structure can be rotated to the first position relative to the bottom cover. At this time, the first air inlet is blocked by the switch structure, that is, air cannot be introduced into the atomizer chamber, while the first sensing hole and the second sensing hole remain connected. The airflow sensing component can be a microphone, etc. One side of the airflow sensing component is connected to the outside atmosphere through the air outlet, and the other side of the airflow sensing component can be connected to the outside atmosphere through the first sensing hole and the second sensing hole. The air pressure on both sides of the airflow sensing component can be kept roughly the same, thereby avoiding the airflow sensing component from being mistakenly triggered due to the pressure difference on both sides. It can be understood that if only one side of the airflow sensing component is connected to the outside atmosphere through the air outlet, and the other side is sealed, when the air pressure on one side of the air outlet changes, the pressure difference on both sides of the airflow sensing component will be mistakenly triggered, thereby causing the atomizer component to be mistakenly started. When the atomizer device is to be used, the switch structure can be rotated to the second position relative to the bottom cover. At this time, the first air inlet is connected to the second air inlet, and the opening is connected to the first sensing hole. When the air outlet of the shell generates negative pressure, such as when the user inhales at the air outlet of the shell, the air pressure on the side where the air flow sensing component is connected to the air outlet decreases, that is, the air flow sensing component detects the pressure difference on both sides and drives the atomizer component to start, and an aerosol that can be inhaled by the user is generated in the atomizer chamber. The air flows through the atomizer chamber from the first air inlet and the second air inlet, and the air entrains the aerosol generated in the atomizer chamber and then flows out from the air outlet together. In other words, whether it is used or not, the first sensing hole on the bottom cover can always be connected to the outside atmosphere, and the two sides of the air flow sensing component can also be always connected to the outside atmosphere, ensuring that the air pressure on both sides of the air flow sensing component is consistent to avoid it being triggered, which is beneficial to energy saving and safety improvement.

[0013] In one embodiment, the atomizing device further includes a charging component disposed in the housing, and a charging port is provided on the bottom cover; when in the first position, the charging port is connected to the opening and the opening exposes the charging component; when in the second position, the switch structure blocks the charging port. In the first position, the charging port exposes the charging component, and a charging cable or the like can be inserted into the charging port to electrically connect to the charging component for charging. At this time, the first air inlet is blocked by the switch structure, while the first sensing hole and the second sensing hole remain connected, so that the air pressure on both sides of the airflow sensing component can be kept consistent to avoid triggering it, thereby ensuring that the atomizing device will not be mistakenly activated in the charging state, further improving safety.

[0014] In one embodiment, one of the switch structure and the bottom cover is provided with a positioning protrusion, and the other of the switch structure and the bottom cover is provided with a positioning recess.

The positioning protrusion can have a certain elasticity, and it can extend into the positioning recess when it is aligned with the positioning recess, and the positioning protrusion can also be moved out of the positioning recess under the action of an external force. When the positioning protrusion extends into the positioning recess, the switch structure just rotates to the first position or the second position relative to the bottom cover. In other words, the positioning protrusion can play a positioning and limiting effect on the movement of the switch structure.

DETAILED DESCRIPTION

[0050] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0051] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the present application provides an atomization device 10, which includes a housing 100, an atomization component 200, an airflow sensing component 300, a bottom cover 400, and a switch structure 500. The top of the housing 100 is provided with an air outlet 120, the atomization component 200 is disposed in the housing 100 and an atomization chamber 221 is formed in the atomization component 200, and the atomization chamber 221 is used to atomize the atomization matrix to form an aerosol. The airflow sensing component 300 is disposed in the housing 100 and is electrically connected to the atomization component 200. Figure 3As shown, the bottom cover 400 is disposed at the bottom end of the shell 100 and a first sensing hole 411 and a first air inlet hole 412 are provided on the bottom cover 400. One side of the airflow sensing component 300 is communicated with the air outlet 120, and the first sensing hole 411 is communicated with the other side of the airflow sensing component 300. The airflow sensing component 300 is used to drive the atomization component 200 to work when an airflow change is sensed. One end of the atomization chamber 221 is communicated with the air outlet 120, and the first air inlet hole 412 is communicated with the other end of the atomization chamber 221. The switch structure 500 is provided with a second sensing hole 521, a second air inlet hole 522 and an opening 510. The switch structure 500 is disposed on the bottom cover 400 and can be rotated to a first position and a second position relative to the bottom cover 400. As shown Figure 3 and Figure 4 As shown, in the first position, the switch structure 500 blocks the first air inlet 412, and the first sensing hole 411 is connected to the second sensing hole 521. Figure 5 and Figure 6 As shown, in the second position, the first air inlet 412 is connected to the second air inlet 522, and the opening 510 is connected to the first sensing hole 411. The atomization matrix may refer to a material that can be atomized to provide aerosol components under certain conditions. For example, the atomization matrix may be one or more of tobacco oil, tobacco liquid, tobacco derivatives, or tobacco substitutes.

[0052] The above-mentioned atomizing device 10 can at least achieve the following beneficial effects: when the atomizing device 10 is not in use, such as when the atomizing device 10 is to be packaged for transportation, charged or placed idle, Figure 3 and Figure 4 As shown, the switch structure 500 can be rotated to the first position relative to the bottom cover 400. At this time, the first air inlet 412 is blocked by the switch structure 500, that is, it is impossible to inlet air into the atomizing chamber 221, while the first sensing hole 411 and the second sensing hole 521 remain connected. The airflow sensing component 300 can be but is not limited to a microphone, etc. One side of the airflow sensing component 300 is connected to the outside atmosphere through the air outlet 120, and the other side of the airflow sensing component 300 can also be connected to the outside atmosphere through the first sensing hole 411 and the second sensing hole 521. Then, the air pressure on both sides of the airflow sensing component 300 can be kept roughly the same, thereby preventing the airflow sensing component 300 from being mistakenly triggered due to the pressure difference on both sides. It can be understood that if only one side of the airflow sensing component 300 is connected to the outside atmosphere through the air outlet 120, and the other side is sealed, when the air pressure on one side of the air outlet 120 changes, the pressure difference on both sides of the airflow sensing component 300 will be mistakenly triggered, thereby causing the atomizing component 200 to be mistakenly started. Figure 5 and Figure 6As shown, when the atomizer device 10 is to be used, the switch structure 500 can be rotated to the second position relative to the bottom cover 400. At this time, the first air inlet hole 412 is connected to the second air inlet hole 522, and the opening 510 is connected to the first sensing hole 411. When negative pressure is generated at the air outlet 120 of the shell 100, such as when the user inhales at the air outlet 120 of the shell 100, the air pressure on the side where the air flow sensing component 300 is connected to the air outlet 120 decreases, that is, the air flow sensing component 300 detects the pressure difference on both sides and drives the atomizer component 200 to start, and an aerosol that can be inhaled by the user is generated in the atomizer chamber 221. The air flows through the atomizer chamber 221 from the first air inlet hole 412 and the second air inlet hole 522, and the air entrains the aerosol generated in the atomizer chamber 221 and then flows out from the air outlet 120 together. In other words, whether in use or not, the first sensing hole 411 on the bottom cover can always remain connected to the outside atmosphere, and the two sides of the airflow sensing component 300 can also always remain connected to the outside atmosphere, ensuring that the air pressure on both sides of the airflow sensing component 300 is consistent to avoid it being triggered, which is beneficial to energy saving and improving safety.

[0053] Specifically, Figure 7 As shown, in some embodiments, the atomizing device 10 further includes a charging assembly 910 disposed in the housing 100, and a charging port 420 is provided on the bottom cover 400. Figure 4 , Figure 7 and Figure 8 As shown, in the first position, the charging port 420 is connected to the opening 510 and the opening 510 exposes the charging assembly 910. Figure 6 As shown, in the second position, the switch structure 500 blocks the charging port 420. Figure 4 , Figure 7 and Figure 8 As shown, in the first position, the charging port 420 exposes the charging component 910, and the charging cable can be inserted into the charging port 420 to electrically connect with the charging component 910 to perform the charging operation. At this time, the first air inlet 412 is blocked by the switch structure 500, while the first sensing hole 411 and the second sensing hole 521 remain connected, which can keep the air pressure on both sides of the airflow sensing component 300 consistent to avoid it being triggered, ensuring that the atomization device 10 will not be accidentally started in the charging state, further improving safety.

[0054] It should be noted that the rotation stroke of the switch structure 500 relative to the bottom cover 400 is controlled by the user. When in use, the switch structure 500 can be rotated to the second position so that the first air inlet 412 and the second air inlet 522 are completely aligned, thereby achieving the maximum air intake; the switch structure 500 can also be rotated relative to the bottom cover 400 to an intermediate position between the first position and the second position, that is, the first air inlet 412 is not completely aligned with the second air inlet 522, the first air inlet 412 and the second air inlet 522 are partially connected, and the air intake does not reach the maximum. In other words, the user can adjust the air intake per unit time by relatively rotating the switch structure 500 and the bottom cover 400 according to actual needs.

[0055] See also Figure 8 and Fig. 9 In some embodiments, one of the switch structure 500 and the bottom cover 400 is provided with a positioning protrusion 710, and the other of the switch structure 500 and the bottom cover 400 is provided with a positioning recess 720. When in the first position or the second position, the positioning protrusion 710 can extend into the positioning recess 720 to limit the rotation of the switch structure 500 relative to the bottom cover 400, and when the switch structure 500 rotates relative to the bottom cover 400 under the action of an external force, the positioning protrusion 710 can be moved out of the positioning recess 720. The positioning protrusion 710 can have a certain elasticity, and can extend into the positioning recess 720 when aligned with the positioning recess 720, and can also be moved out of the positioning recess 720 under the action of an external force. When the locking protrusion 710 extends into the locking recess 720 , the switch structure 500 just rotates to the first position or the second position relative to the bottom cover 400 . In other words, the locking protrusion 710 can position and limit the movement of the switch structure 500 .

[0056] For example, in some embodiments, the locking protrusion 710 includes a first locking protrusion 711, and the locking recess 720 includes a first locking recess 721 and a second locking recess 722. When in the first position, the first locking protrusion 711 extends into the first locking recess 721, and when in the second position, the first locking protrusion 711 extends into the second locking recess 722.

[0057] For example, in some embodiments, the locking protrusion 710 includes a first locking protrusion 711 and a second locking protrusion 712, and the locking recess 720 includes a first locking recess 721. When in the first position, the first locking protrusion 711 extends into the first locking recess 721, and when in the second position, the second locking protrusion 712 extends into the first locking recess 721.

[0058] For example, in some embodiments, the locking protrusion 710 includes a first locking protrusion 711 and a second locking protrusion 712, and the locking recess 720 includes a first locking recess 721 and a second locking recess 722. When in the first position, the first locking protrusion 711 extends into the first locking recess 721, and the second locking protrusion 712 extends into the second locking recess 722. When in the second position, the first locking protrusion 711 extends into the second locking recess 722, and the second locking protrusion 712 extends into the first locking recess 721.

[0059] In some embodiments, the number of the positioning protrusions 710 and the number of the positioning recesses 720 are both set to be multiple, and the multiple positioning protrusions 710 and the multiple positioning recesses 720 are arranged at intervals along the circumference of the bottom cover 400. Figure 8 and Fig. 9 In the illustrated embodiment, the positioning convex portion 710 includes a first positioning convex portion 711, a second positioning convex portion 712, a third positioning convex portion 713, and a fourth positioning convex portion 714, and the positioning concave portion 720 includes a first positioning concave portion 721, a second positioning concave portion 722, a third positioning concave portion 723, and a fourth positioning concave portion 724.

When the first assembly portion 810 and the limiting portion 830 rotate relative to the extreme position, the switch structure 500 is in the first position or the second position, which is convenient for user operation.

[0062] For example, in some other embodiments, the bottom cover 400 is provided with the first assembly portion 810, and the switch structure 500 is provided with the second assembly portion 820, the second assembly portion 820 is an assembly opening that passes through the switch structure 500, the limiting portion 830 extends in an open ring shape at the periphery of the assembly opening, one end of the first assembly portion 810 is rotatably inserted into the assembly opening, and a limiting rib 813 is provided on the outer circumferential surface of the first assembly portion 810; when the limiting rib 813 abuts against the first side, the switch structure 500 rotates to the first position relative to the bottom cover 400, and when the limiting rib 813 abuts against the second side, the switch structure 500 rotates to the second position relative to the bottom cover 400.

[0064] Furthermore, if Fig. 9 As shown, in some embodiments, the edge of the limiting rib 813 is provided with a guiding slope 814, and the guiding slope 814 is used to abut against the inner wall of the assembly opening to guide the first assembly part 810 to pass through the assembly opening. The guiding slope 814 can guide the first assembly part 810 to pass through the assembly opening, reducing the difficulty of assembling the switch structure 500 and the bottom cover 400.

[0065] See also Fig. 9 In some embodiments, the first assembly portion 810 includes a first shaft section 811 provided on the switch structure 500 and a second shaft section 812 connected to the first shaft section 811, the first shaft section 811 is rotatably provided in the assembly port, the second shaft section 812 is located outside the assembly port, and the outer peripheral surface of the second shaft section 812 is provided with the limiting rib 813, and the limiting portion 830 is provided on the side of the bottom cover 400 facing away from the switch structure 500.

The cross-sectional outer contour of the second shaft segment 812 is larger than the cross-sectional inner contour of the assembly port. During assembly, since the second shaft segment 812 has a certain elasticity, the second shaft segment 812 can squeeze through the assembly port under the action of an external force; when assembled, since the cross-sectional outer contour of the second shaft segment 812 is larger than the cross-sectional inner contour of the assembly port, the assembly port can limit the second shaft segment 812 to prevent it from falling out.
