Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic atomization, and in particular to an electronic atomization device. BACKGROUND

[0002] Tobacco products, such as cigarettes, cigars, and the like, burn tobacco during use to produce tobacco smoke. Attempts have been made to provide alternatives to these burning tobacco products by creating products that release compounds without burning.

[0087] For the purposes of the present application, the present application will be described in greater detail below, in connection with the accompanying drawings and the detailed description.

[0088] The present application proposes an electronic atomization device for atomizing a liquid substrate to generate an aerosol.

[0089] Figure 1 And Figure 2 A schematic view of an electronic atomization device of one embodiment is shown, including several components disposed within an outer body or housing (which can be referred to as a shell). The overall design of the outer body or housing can vary, and the version or configuration of the outer body that defines the overall size and shape of the electronic atomization device can vary. Generally, the outer body or housing can be formed from a single, unitary shell, or the outer body or housing can be formed from two or more separable bodies.

[0090] In some embodiments, the outer body or housing of the electronic atomization device substantially defines the outer surface of the electronic atomization device; in Figures 1 to 8 In the particular embodiment shown, the shell of the electronic atomization device can include one or more reusable components. In some examples, all or only a portion of the shell can be formed from a metal or alloy, such as stainless steel, aluminum, or other suitable materials including various plastics (e.g., polycarbonate), metal-plating over plastic, ceramic, and the like.

[0091] In particular in Figures 1 to 8 The electronic atomization device is configured to be substantially flat circular in shape. A lanyard hole 119 is disposed on the shell of the electronic atomization device; to facilitate a user to attach or apply a lanyard to the electronic atomization device through the lanyard hole 119, to facilitate carrying the electronic atomization device on the body.

[0092] According to Figures 1 to 8 As shown, the electronic atomization device includes:

[0093] A proximal end 110 and a distal end 120 opposite in a longitudinal direction; in use, the proximal end 110 is the end close to the user for puffing; the distal end 120 is the end away from the user.

[0094] In embodiments, the electronic atomization device is configured to be puffed by a user through the nostrils, rather than through the mouth.

[0095] In Figures 1 to 8 As shown, the electronic atomization device includes:

[0096] The first air outlet 141 and the second air outlet 142 are arranged at intervals in the width direction. The first air outlet 141 and the second air outlet 142 are used to output aerosol. The first air outlet 141 and the second air outlet 142 have a recessed structure 143 therebetween, so that the first air outlet 141 and the second air outlet 142 are arranged on two protruding portions of the surface of the proximal end 110 of the electronic atomization device respectively.

[0097] Or in an embodiment, the electronic atomization device comprises:

The recessed structure 143 is located between the first protruding portion and the second protruding portion.

[0099] In use, the user inserts the first protruding portion of the electronic atomization device into one nostril and the second protruding portion into the other nostril, and then sucks the first air outlet 141 and the second air outlet 142 through the nostrils. In use, the recessed structure 143 is used for the nasal septum between the two nostrils to extend in when the user sucks through the public nose, so as to prevent the insertion of the first protruding portion into one nostril and the second protruding portion into the other nostril from being blocked.

[0100] Wherein, "nasal septum" is a biological term or medical term, which refers to the tissue structure between the left and right nostrils.

[0101] In an embodiment, the first air outlet 141 and the second air outlet 142 output aerosol at the same time; the user can suck aerosol through the first air outlet 141 and the second air outlet 142 at the same time. And in an embodiment, in order to facilitate the user to inhale through the nose, the distance between the first air outlet 141 and the second air outlet 142 is basically the distance size between the left and right nostrils of human; for example, in some specific embodiments, the distance between the first air outlet 141 and the second air outlet 142 is about 10-20mm.

Along the width direction of the electronic atomization device, the first air outlet 141 and the second air outlet 142 are respectively located on the two sides of the recessed structure 143.

[0105] Specifically, the surface of the first shell 12 has a mounting groove 124 recessed relative to other portions; after assembly, the cap 11 is mounted or arranged in the mounting groove 124. When the cap 11 is mounted or arranged in the mounting groove 124, the cap 11 is flatly engaged with the outer surface of the first shell 12.

[0106] In Figures 1 to 8 In the illustrated embodiment, the first shell 12 is provided with a first connecting structure 125, and the cap 11 is provided with a second connecting structure 118.

[0191] In some embodiments, the airflow sensor 82 is, for example, a microphone sensor or a MEMS sensor, etc. In embodiments, the airflow sensor 82 is arranged on the circuit board 80, and the circuit board 80 is arranged on the base 70. Figures 3 to 9As shown, the airflow sensor 82 includes a first sensing surface 821 and a second sensing surface 822 opposite to each other. The second sensing surface 822 faces the distal end 120. In embodiments, the first sensing surface 821 and the second sensing surface 822 are isolated from each other.

The airflow sensor 82 determines the user's puffing action according to the pressure difference sensed by the first sensing surface 821 and the second sensing surface 822.

[0192] According to Figures 3 to 9 As shown, the electronic atomization device further comprises:

[0193] The wrapping element 81 is made of a flexible material such as silicone. The wrapping element 81 has a wrapping portion 811 wrapping the airflow sensor 82.

[0196] The sensing connection channel 812 penetrates or extends from the first sensing surface 821 to the plug-in slot 815 of the connecting portion 813. The sensing connection channel 812 provides airflow communication between the first sensing surface 821 and the air inlet channel, and thus enables the first sensing surface 821 to sense the pressure of the air inlet channel.

[0197] According to Figures 3 to 9 As shown, the electronic atomization device further comprises:

[0198] A removable sealing plug 135 extends at least partially from the air inlet 133 into the air intake tube 74 to simultaneously block the air inlet 133 and the sensing connection channel 812. For example, in the retail state after the e-cigarette device has been manufactured and packaged, the sealing plug 135 extends from the air inlet 133 into the air intake tube 74, thus blocking and closing the air inlet 133 and the sensing connection channel 812 when the e-cigarette device is sold. Before use, as... Figures 3 to 9 As shown by the middle arrow P10, the user can remove or pull out the sealing plug 135 from the air inlet 133, thereby opening the air inlet 133 and the sensing connection channel 812.

[0199] according to Figure 8 As shown, the electronic atomizing device also includes:

[0200] The aerosol output channel provides a path for outputting aerosols from the atomization chamber 530.

[0201] In the embodiments, for example Figures 3 to 19 As shown, the bracket 30 also defines the following:

[0202] A window 324 is formed or arranged on one or both sides of the support 30 in the width direction; the window 324 extends from the side surface of the support 30 in the width direction to the receiving cavity 331. The window 324 communicates with the receiving cavity 331 and the atomizing chamber 530. In use, as... Figures 3 to 19 As indicated by the middle arrow R2, window 324 provides a path for the aerosol from atomizing chamber 530 to bypass receiving chamber 331 and / or atomizing assembly 50 and be output to outlet pipe 123.

[0203] Accordingly Figure 15 As shown, the first sealing portion 41 is provided with:

[0204] A clearance opening 413 is formed or located on the sidewall of the first sealing portion 41. When the atomizing assembly 50 is accommodated or located within the first sealing portion 41, the second surface 520 and / or the atomizing chamber 530 communicate with the window 324 through the clearance opening 413.

[0205] Specifically according to Figures 11 to 16 As shown, window 324 has a bottom wall 325 facing the distal end 120; the second surface 520 is closer to the proximal end 110 than the bottom wall 325.

[0206] according to Figures 11 to 16 As shown, the aerosol output channel includes:

[0207] The first aerosol output channel R21 provides a first channel path for delivering aerosols to the first outlet 141;

[0208] The second aerosol output channel R22 provides a second channel path for delivering aerosol to the second air outlet 142.

[0209] In embodiments, the first and second aerosol output channels R21 and R22 are for delivering aerosol generated by the same one atomization assembly 50 to the first and second air outlets 141 and 142, respectively; rather than delivering aerosol generated by two different atomization assemblies 50 to the first and second air outlets 141 and 142, respectively.

[0210] Specifically, according to Figures 3 to 10 As shown, the first and second aerosol output channels R21 and R22 are at least partially formed or defined between the first housing 12 and the cap 11. For example, the first and second aerosol output channels R21 and R22 comprise a slit or gap formed between the first housing 12 and the cap 11.

[0211] Specifically, according to Figures 3 to 10 As shown, the first aerosol output channel R21 further comprises a first tubular wall 116 formed on the cap 11; the first tubular wall 116 is arranged extending from the first air outlet 141 towards the distal end 120. The second aerosol output channel R22 further comprises a second tubular wall 117 formed on the cap 11; the second tubular wall 117 is arranged extending from the second air outlet 142 towards the distal end 120.

[0212] According to Figures 3 to 10 As shown, the air outlet tube 123 has a section 128 with increasing diameter; the section 128 with increasing diameter is configured to be in the shape of a trumpet or bell mouth. The diameter of the section 128 with increasing diameter gradually increases in the direction close to the proximal end 110. It is advantageous for the aerosol output by the air outlet tube 123 to be divided into two streams output via the first and second aerosol output channels R21 and R22.

[0213] In embodiments, the first and second aerosol output channels R21 and R22 are arranged mirror-imaged or symmetrically. In embodiments, the first and second aerosol output channels R21 and R22 have substantially the same path length. Then, when the user inhales through both nostrils at the same time, the two streams of airflow in the first and second aerosol output channels R21 and R22 do not generate vortex, which is advantageous for nasal inhalation.

[0214] Or in some other variant embodiments, the first and second aerosol output channels R21 and R22 have different path lengths; the different path lengths are to form aerosol output in a time sequence.

[0215] In embodiments, at least part of the first aerosol output channel R21 and / or the second aerosol output channel R22 is curved. For example, the part of the first aerosol output channel R21 and / or the second aerosol output channel R22 between the first housing 12 and the cap 11 is curved; more preferably, the part of the first aerosol output channel R21 and / or the second aerosol output channel R22 between the first housing 12 and the cap 11 is arcuately curved.

[0216] In embodiments, at least part of the first aerosol output channel R21 and / or the second aerosol output channel R22 is away from each other in a direction close to the proximal end 110. For example, the arcuately curved part of the first aerosol output channel R21 between the first housing 12 and the cap 11 and the arcuately curved part of the second aerosol output channel R22 between the first housing 12 and the cap 11 are away from each other in a direction close to the proximal end 110.

[0217] According to Figures 3 to 10 As shown in FIG. 1, the electronic atomization device further comprises:

[0218] The flexible sealing gasket 15, made of flexible silicone or the like, provides sealing at least between the first housing 12 and the cap 11. The sealing gasket 15 is annular with a perforation 151. The sealing gasket 15 has a positioning protrusion 153; the first housing 12 has a positioning groove 127. In assembly, the positioning protrusion 153 of the sealing gasket 15 is inserted into the positioning groove 127 of the first housing 12, so as to provide positioning in assembly of the sealing gasket 15 and the first housing 12, and to provide retention after assembly. The perforation 151 of the sealing gasket 15 is aligned with and communicates with the air outlet tube 123 of the first housing 12. In turn, the aerosol output from the air outlet tube 123 is divided into two paths after passing through the perforation 151 of the sealing gasket 15, and then output to the first air outlet 141 via the first aerosol output channel R21 and to the second air outlet 142 via the second aerosol output channel R22, respectively. After assembly, the first tubular wall 116 and the second tubular wall 117 are against the sealing gasket 15.

[0219] In particular, according to Figures 3 to 10 As shown in FIG. 1, the flexible sealing gasket 15 is arranged with a convex rib 152 on the surface thereof facing the cap 11; the convex rib 152 is a closed annular around the perforation 151.

[0220] According to Figures 3 to 10 As shown in FIG. 1, the sealing gasket 15 is arranged substantially perpendicular to the longitudinal direction of the electronic atomization device. In embodiments, the flexible sealing gasket 15 is arcuately curved, or curved. In particular in Figures 3 to 10 the sealing gasket 15 is curved towards the distal end 120.

[0221] In embodiments, the first and second aerosol output channels R21 and R22 are not completely separated or independent, or parts of the first and second aerosol output channels R21 and R22 are shared; for example, the first aerosol output channel R21 is shared in the part of the path between the atomization chamber 530 and the sealing gasket 15. And,

[0222] Or in embodiments, the part of the first aerosol output channel R21 between the sealing gasket 15 and the first air outlet 141 is separated or independent from the part of the second aerosol output channel R22 between the sealing gasket 15 and the first air outlet 141.

[0223] In embodiments, the first and second aerosol output channels R21 and R22 are both bypassing the recessed structure 143.

[0225] The airflow channel includes the above-mentioned air inlet channel extending from the air inlet 133 to the atomization chamber 530, and the aerosol output channel extending from the atomization chamber 530 to the first and second air outlets 141 and 142.

[0226] In embodiments, the airflow channel longitudinally passes through the electronic chamber 131 and the liquid storage chamber 121, but is isolated from both the electronic chamber 131 and the liquid storage chamber 121. For example, the part of the airflow channel passing through the electronic chamber 131 is independently surrounded by the air inlet tube 74 of the base 70 to define an isolation from the electronic chamber 131. And, the two ends of the first communication hole 743 are respectively plugged and closed by the flexible first and second plugs 75 and 76 to define an isolation from the electronic chamber 131.

[0227] In embodiments, all the paths through which the complete airflow channel flows are sealed; in particular, all the rigid components through which the complete airflow channel flows are plugged or sealed by flexible sealing elements or sealing materials. For example, the first and second sealing elements 20 and 40, the first and second plugs 75 and 76, the sealing gasket 15, etc., all provide sealing between the components through which the airflow channel passes, which is advantageous for preventing seepage.

Specifically, according to Figures 3 to 19As shown by arrow R3, when the negative pressure in the reservoir 121 exceeds a predetermined threshold, air in the aerosolization chamber 530 / retention pocket 711 passes into the reservoir 121 via a path through the first air exchange slot 714, the air exchange aperture 321, the at least one capillary channel 320, and the second air exchange slot 34, in that order, to relieve the negative pressure in the reservoir 121. When the supersaturated liquid substrate is injected into the reservoir 121 during production or when the pressure in the reservoir 121 is greater than the external pressure during use, the liquid substrate in the reservoir 121 can flow outwardly through the air exchange passage against the direction shown by arrow R3 to equalize the pressure difference between the reservoir 121 and the external environment.

[0242] According to Figure 19 Figures 3 to 19 As shown, the air exchange passage is at least partially formed between the second sealing portion 42 of the second sealing element 40 and the base portion 710 of the base 70. Also, a portion of the passage path of the air exchange passage is defined by the at least one capillary channel 320.

[0243] In embodiments, the air exchange passage is at least partially formed between the holder 30 and the first sealing element 20. For example, in embodiments, the second air exchange slot 34 defines a passage path of the air exchange passage between the holder 30 and the first sealing element 20.

[0244] It should be noted that the preferred embodiments of the present application are shown in the drawings and described above, but the present application is not limited to the embodiments described in the specification, and further, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should be within the scope of the appended claims of the present application.
