Description

Technical Field

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

[0002] An electronic atomization device usually has an air flow channel and a starting air passage communicating with the air flow channel, and a microphone is arranged in the starting air passage to control the operation of the atomization component through the microphone, so that the atomization liquid is atomized into aerosol under the operation of the atomization component for use by users as an electronic product.

[0003] When a user uses an electronic atomization device, an air flow is generated in the air flow channel, causing a negative pressure in the starting air passage, and further causing the conductive film of the microphone to deform, resulting in a capacitance change of the microphone to control the operation of the atomization component.

[0004] After the user stops using the electronic atomization device, some uncondensed aerosol will flow back into the starting air passage under the influence of air pressure. When the aerosol condenses into liquid in the starting air passage, it will interfere with the normal operation of the microphone, and even damage the microphone, resulting in the self-starting of the electronic atomization device. In severe cases, it will even cause the electronic atomization device to catch fire, leading to major safety accidents. Utility Model Content

[0007] The housing assembly is provided with an air flow channel, a liquid storage cavity, and a starting air passage. The air flow channel is communicated with the outside, and the liquid storage cavity and the starting air passage are respectively communicated with the air flow channel;

[0008] The atomization component is arranged at the communication position of the air flow channel and the liquid storage cavity;

[0009] The microphone is arranged in the housing assembly and is electrically connected to the atomization component to control the operation of the atomization component;

[0010] A convex portion is protruded on the end surface of the starting air passage away from the air flow channel. The outer wall of the circumferential side of the convex portion is spaced from the inner wall of the circumferential side of the starting air passage, and a ventilation hole communicating with the microphone is opened on the end surface of the convex portion.

[0011] In some embodiments of the present application, the shell assembly includes a bracket and a mounting seat, the bracket is provided with an air groove along the vertical direction, the air groove is connected to the air flow channel above the vertical direction, the mounting seat is arranged at the slot below the air groove in the vertical direction, and is enclosed with the air groove to form the starting air channel, and the protrusion is located on the mounting seat.

[0012] In some embodiments of the present application, the microphone is installed on a side of the mounting base facing away from the air groove, and the mounting base is provided with a through hole extending through the vertical direction. The shell assembly also includes a hollow tube body, which is installed in the through hole, and one end of the hollow tube body is connected to the microphone, and the other end of the hollow tube body is protruding from a side of the mounting base facing away from the microphone to form the protrusion.

[0013] In some embodiments of the present application, the protrusion and the mounting seat are integrally formed.

[0014] In some embodiments of the present application, the bracket is provided with a cooling groove connected to the starting airway above the vertical direction, and the shell assembly also includes a liquid storage tank, which is connected to the bracket and covers the notch of the cooling groove to enclose a cooling cavity. The liquid storage tank is penetrated by the airflow channel, one end of the airflow channel is connected to the outside and is provided with a suction nozzle, and the other end of the airflow channel is connected to the cooling cavity.

[0015] In some embodiments of the present application, the bracket is also provided with an air inlet channel connected to the cooling cavity, and the air inlet channel is connected to the outside world at one end away from the cooling cavity, so that the air flow channel is connected to the outside world through one end away from the suction nozzle through the cooling cavity and the air inlet channel.

[0016] In some embodiments of the present application, a switch is movably provided at one end of the air intake passage away from the cooling chamber to movably open or close the air intake passage.

[0017] In some embodiments of the present application, the shell assembly further includes a shell, the shell is provided with an air inlet hole connected to the air inlet channel, the shell is further provided with a slide groove at the air inlet hole, and the switch is slidably installed in the slide groove.

[0018] In some embodiments of the present application, a connecting hole communicating with the air inlet passage is formed on the bottom wall of the cooling groove, and a stop ring is further provided on the periphery of the connecting hole extending along the vertical direction.

[0020] The electronic atomization device provided by the present application, when in use by a user, drives external air into the air flow channel by the user sucking at one end of the air flow channel.

In this way, the atomization liquid can be atomized into aerosol under the operation of the atomization component for the user to inhale and use; after the user stops using it, the uncondensed part of the aerosol flows back into the starting airway.

At the same time, the atomization liquid leaked from the liquid storage cavity can also be stored between the outer wall on the circumference of the convex part and the inner wall on the circumference of the starting airway through the air flow channel, avoiding the contact between the leaked atomization liquid and the microphone, thereby preventing the electronic atomization device from self-starting. In addition, the microphone is communicated with the starting airway through the air permeable holes on the convex part, and is arranged at an interval between the outer wall on the circumference of the convex part and the inner wall on the circumference of the starting airway. It can be known that the inner diameter of the air permeable hole must be smaller than the inner diameter of the starting airway. In this way, the negative pressure of the starting airway is transmitted to the microphone through the air permeable hole, thereby reducing the space volume of the communication path between the microphone and the air flow channel, enabling the microphone to quickly sense the air flow in the air flow channel, improving the starting speed of the microphone, and enhancing the user experience.

[0032] Please refer to Figures 1 to 4 , This application proposes an electronic atomization device 100, and the electronic atomization device 100 includes a housing assembly 10, an atomization assembly 20 and a microphone head 30.

[0033] This electronic atomization device 100 can also be referred to as an electronic cigarette. When in use, the user inhales at one end of the air flow channel 142, driving external air into the air flow channel 142, and sucking the aerosol in the air flow channel 142 into the mouth through the air flow with suction, thus realizing the suction process.

[0034] The housing assembly 10 is provided with an air flow channel 142, a liquid storage cavity 141, and a starting air duct 18. The air flow channel 142 is communicated with the outside. The liquid storage cavity 141 and the starting air duct 18 are respectively communicated with the air flow channel 142. The atomization assembly 20 is arranged at the communication position between the air flow channel 142 and the liquid storage cavity 141. The microphone 30 is arranged in the housing assembly 10 and is electrically connected to the atomization assembly 20 to control the operation of the atomization assembly 20. A convex portion is provided on the end surface of the starting air duct 18 far from the air flow channel 142. The outer wall of the circumferential side of the convex portion is spaced from the inner wall of the circumferential side of the starting air duct 18. A ventilation hole 131 communicated with the microphone 30 is provided on the end surface of the convex portion.

[0035] The outer contour shape of the housing assembly 10 has various forms. The housing assembly 10 can be in the shape of a long rod, or it can also be in the shape of a cuboid box. Generally, the housing assembly 10 is composed of multiple components, and different components can be made of different materials. It can be understood that the air flow channel 142, the liquid storage cavity 141, and the starting air duct 18 provided in the housing assembly 10 can also be formed by splicing two or more components.

[0036] It should be noted that usually, the opening at one end of the air flow channel 142 is directly exposed on the outer surface of the housing assembly 10 for the user to directly suck with the mouth. The opening at the other end of the air flow channel 142 can be directly exposed on the outer surface of the housing assembly 10, or can be indirectly communicated with the outside through the air intake channel 114, or can also be indirectly communicated with the outside through the air intake port.

[0037] The liquid storage cavity 141 is used to store the atomization liquid. The atomization assembly 20 is arranged at the communication position between the air flow channel 142 and the liquid storage cavity 141. In this way, the atomization liquid in the liquid storage cavity 141 can directly enter the atomization cavity of the atomization assembly 20. After the atomization assembly 20 atomizes the atomization liquid, the aerosol can also directly flow out along the air flow channel 142.

[0038] The electronic atomization device 100 provided by the present application, when in use by a user, drives external air into the air flow channel 142 by the user inhaling at one end of the air flow channel 142. At this time, since the starting airway 18 is communicated with the air flow channel 142, a negative pressure is generated in the starting airway 18 under the influence of the air flow. At the same time, since the microphone 30 is communicated with the starting airway 18 through the air permeable holes 131 on the convex part, the conductive film of the microphone 30 deforms, and then a capacitance change is generated to control the operation of the atomization component 20. In this way, the atomization liquid can be atomized into aerosol under the operation of the atomization component 20 for the user to inhale and use; after the user stops using it, the uncondensed part of the aerosol flows back into the starting airway 18. When the aerosol condenses into liquid in the starting airway 18, it can be stored between the outer wall of the circumferential side of the convex part and the inner wall of the circumferential side of the starting airway 18, avoiding the contact between the condensate and the microphone 30, thereby preventing the electronic atomization device 100 from self-starting. At the same time, the atomization liquid leaked from the liquid storage cavity 141 can also be stored between the outer wall of the circumferential side of the convex part and the inner wall of the circumferential side of the starting airway 18 through the air flow channel 142, avoiding the contact between the leaked atomization liquid and the microphone 30, thereby preventing the electronic atomization device 100 from self-starting. In addition, the microphone 30 is communicated with the starting airway 18 through the air permeable holes 131 on the convex part, and is spaced from the inner wall of the circumferential side of the starting airway 18 by the outer wall of the circumferential side of the convex part. It can be known that the inner diameter of the air permeable holes 131 must be smaller than the inner diameter of the starting airway 18. In this way, the negative pressure of the starting airway 18 is transmitted to the microphone 30 through the air permeable holes 131, thereby reducing the space volume of the communication path between the microphone 30 and the air flow channel 142, enabling the microphone 30 to quickly sense the air flow in the air flow channel 142, improving the starting speed of the microphone 30, and improving the user experience.

[0039] In some embodiments, as Figure 2 and Figure 4 shown, the housing assembly 10 includes a bracket 11 and a mounting seat 12. The bracket 11 is provided with an air groove in the vertical direction. The upper part of the air groove in the vertical direction is communicated with the air flow channel 142. The mounting seat 12 is arranged at the notch of the air groove in the lower part in the vertical direction, and encloses with the air groove to form the starting airway 18. The convex part is located on the mounting seat 12.

[0040] It should be noted that the mounting seat 12 can be arranged at the notch of the air groove in the lower part in the vertical direction by connecting with the bracket 11, or the mounting seat 12 can also be arranged at the notch of the air groove in the lower part in the vertical direction by connecting with other components of the housing assembly 10.

[0041] The convex part can be integrally provided with the mounting base 12. In some examples, the convex part is integrally formed with the mounting base 12. In some examples, the convex part is provided on the mounting base 12 by means of fixed connection. The mounting base 12 also provides a mounting position for other components of the electronic atomization device 100. For example, it provides a mounting position for the circuit board.

[0042] Such a setting is intended to facilitate the processing or assembly of the convex part.

[0043] In some embodiments, as Figure 2 and Figure 4 shown, a microphone 30 is installed on the side of the mounting base 12 facing away from the air groove. The mounting base 12 is provided with a through hole 121 penetrating in the vertical direction. The housing assembly 10 further includes a hollow tube 13. The hollow tube 13 is installed in the through hole 121, and one end of the hollow tube 13 is communicated with the microphone 30. The other end of the hollow tube 13 protrudes from the side surface of the mounting base 12 facing away from the microphone 30 to form a convex part.

[0044] The hollow tube 13 can be installed in the through hole 121 in a detachable manner. For example: plugging, threaded connection; the hollow tube 13 can also be installed in the through hole 121 in a non-detachable manner. For example: bonding.

[0045] Such a setting is intended to further facilitate the assembly of the convex part.

[0046] Considering that, in some examples, as Figures 2 to 4 shown, a part of the mounting base 12 is embedded in the notch of the air groove and encloses a starting air passage 18 with the air groove. Thus, when a part of the mounting base 12 is assembled in the air groove, the starting air passage 18, a part of the mounting base 12, and the ventilation holes 131 may all be deformed due to being squeezed, affecting the size of the ventilation holes 131. The mounting base 12 has a microphone mounting part 122 for mounting the microphone 30. The through hole 121 is formed in the microphone mounting part 122. The material of the microphone mounting part 122 is a flexible material, and / or the side wall material of the starting air passage 18 is a flexible material. Such a setting enables the outer wall of the hollow tube 13 to support and stabilize the inner wall of the through hole 121 of the microphone mounting part 122 and the inner wall of the starting air passage 18, so that the ventilation holes 131 and the through hole 121 can better withstand the external force, thereby making the connection between the ventilation holes 131 and the microphone 30 more stable.

[0047] In some embodiments, the convex part is integrally formed with the mounting base 12. The convex part and the mounting base 12 can be made by processes such as injection molding and hot pressing. In some examples, the convex part and the mounting base 12 are made of silica gel material to improve the airtightness of the starting air passage 18. Such a setting is intended to improve the production efficiency of the electronic atomization device 100.

[0048] In some embodiments, as Figures 1 to 4 shown, a cooling groove 113 communicating with the starting air passage 18 is provided above the bracket 11 in the vertical direction. The housing assembly 10 further includes a liquid storage chamber 14. The liquid storage chamber 14 is connected to the bracket 11 and covers the notch of the cooling groove 113 to enclose a cooling cavity 19. An air flow passage 142 is provided through the liquid storage chamber 14. One end of the air flow passage 142 communicates with the outside and is provided with a suction nozzle 15, and the other end of the air flow passage 142 is communicated with the cooling cavity 19.

[0049] With such a setting, it is intended to reduce the backflow of the uncondensed aerosol into the starting air passage 18 under the influence of air pressure when the user stops using the electronic atomization device 100. In addition, after the aerosol condenses in the cooling cavity 19, it can be stored in the condensation cavity, avoiding the condensate flowing into the starting air passage 18.

[0050] In some embodiments, as Figures 2 to 4 shown, the bracket 11 is further provided with an air intake passage 114 communicating with the cooling cavity 19. One end of the air intake passage 114 away from the cooling cavity 19 communicates with the outside, so that one end of the air flow passage 142 away from the suction nozzle 15 communicates with the outside through the cooling cavity 19 and the air intake passage 114.

[0051] With such a setting, when the electronic atomization device 100 is in use, the user inhales at one end of the air flow passage 142 to drive the outside air to enter the air flow passage 142 through the air intake passage 114 and the cooling cavity 19. Of course, in other embodiments, an air intake port communicating with the outside can be opened on the groove wall of the cooling groove 113.

[0052] In some embodiments, as Figure 2 and Figure 3 shown, a switch 16 is further movably provided at one end of the air intake passage 114 away from the cooling cavity 19 to movably open or close the air intake passage 114. With such a setting, when the user does not use the electronic atomization device 100, the air intake passage 114 can be closed through the switch 16 to avoid gas flow in the air flow passage 142 and the starting air passage 18, prevent the electronic atomization device 100 from self-starting, and improve the safety of the electronic atomization device 100.

[0053] In some embodiments, as Figure 1 and Figure 2 shown, the housing assembly 10 further includes a housing 17. The housing 17 is provided with an air intake hole 171 communicating with the air intake passage 114, and the housing 17 is further provided with a sliding groove 172 at the air intake hole 171. The switch 16 is slidably installed in the sliding groove 172. With such a setting, it is intended to facilitate the user to open or close the air intake passage 114. Of course, in other embodiments, the switch 16 can also be rotatably installed on the housing 17.

[0054] In some embodiments, as Figures 2 to 4As shown, a connection hole 115 communicating with the air intake passage 114 is formed in the bottom wall of the cooling tank 113, and a stop ring 111 is further arranged along the vertical direction at the periphery of the connection hole 115. Such an arrangement is intended to prevent the aerosol from flowing into the air intake passage 114 after condensation. Of course, in other embodiments, the connection hole 115 communicating with the air intake passage 114 may be formed in the peripheral wall of the cooling tank 113,

[0055] The bracket 11 is further provided with a battery compartment for storing a battery that provides electrical energy for the electronic atomization device 100. In one embodiment, the air intake passage 114 and the battery compartment share a chamber. In another embodiment, the bracket 11 is provided with a pipe passing through the battery compartment, and the interior of the pipe forms the air intake passage 114.

[0056] In some embodiments, such as Figure 2 and Figure 4 As shown, a tapered flared opening 112 is formed in the wall of the cooling tank 113, and the flared opening 112 communicates with the starting air passage 18. With such an arrangement, the gas flows in the air flow passage 142 and the cooling chamber 19, which is conducive to generating negative pressure in the starting air passage 18, aiming to improve the sensitivity of the microphone 30.

[0057] The above are only the optional embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structural transformation made by using the content of the specification and drawings of the present application under the inventive concept of the present application, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
