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.

For example, the material can be tobacco or other non-tobacco products, which can or can not contain nicotine. As another example, there are aerosol provision devices, such as so-called electronic atomization devices. These devices typically contain a liquid that is heated to cause it to vaporize, thereby producing an inhalable aerosol. The liquid can include nicotine and / or flavorings and / or an aerosol generating substance, such as glycerol. Known electronic atomization devices provide air intake through a gap between an electric core and a housing. SUMMARY

[0124] To facilitate understanding of this application, a more detailed description of this application will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0125] This application proposes an electronic atomizing device for atomizing a liquid matrix to generate an aerosol.

[0126] Figure 1 and Figure 2 A schematic diagram of an embodiment of an electronic atomizing device is shown, including several components disposed within an outer body or housing (which may be referred to as a casing). The overall design of the outer body or housing may vary, and the type or configuration of the outer body that defines the overall size and shape of the electronic atomizing device may vary. Typically, the outer body or housing may be formed from a single integral casing, or the outer body or housing may be formed from two or more separable bodies.

[0127] In some embodiments, the outer body or housing of the electronic atomizing device substantially defines the outer surface of the electronic atomizing device; Figures 1 to 8In the illustrated embodiment, the housing of the electronic atomization device can include one or more reusable components. In some examples, all or only a portion of the housing 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.

[0128] In particular embodiments, Figures 1 to 8 The electronic atomization device is configured to be substantially flat circular shape. The housing of the electronic atomization device is provided with a lanyard hole 119; so as to facilitate the user to connect or apply a lanyard on the electronic atomization device through the lanyard hole 119, thereby facilitating the user to carry it on the body.

[0129] According to Figures 1 to 8 The electronic atomization device comprises:

[0130] A proximal end 110 and a distal end 120 opposite to each other in the longitudinal direction; in use, the proximal end 110 is the end close to the user's suction; the distal end 120 is the end away from the user.

[0131] In embodiments, the electronic atomization device is configured to be used by the user to inhale through the nostrils, rather than through the mouth.

[0132] In Figures 1 to 8 The electronic atomization device comprises:

[0133] A first air outlet 141 and a second air outlet 142 are arranged spaced apart 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 recess structure 143 therebetween, so that the first air outlet 141 and the second air outlet 142 are arranged on two protruding portions of the proximal end 110 of the electronic atomization device, respectively.

[0134] Or in embodiments, the electronic atomization device comprises:

[0135] A first protruding portion and a second protruding portion are located at the proximal end 110, and the first protruding portion and the second protruding portion are arranged spaced apart in the width direction; the first air outlet 141 is formed or arranged on the first protruding portion, and the second air outlet 142 is formed or arranged on the second protruding portion. The recess structure 143 is located between the first protruding portion and the second protruding portion.

[0136] In use, a user inserts the first protruding portion of the electronic atomization device into one nostril, 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, so as to prevent the insertion of the first protruding portion into one nostril and the second protruding portion into the other nostril from forming an obstruction.

[0137] Wherein, "nasal septum" is a biological term or medical term, which refers to the tissue structure between the left and right nostrils.

[0138] In embodiments, the first air outlet 141 and the second air outlet 142 output aerosol at the same time; a user can suck aerosol through the first air outlet 141 and the second air outlet 142 at the same time. In embodiments, 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 a human being; for example, in some specific embodiments, the distance between the first air outlet 141 and the second air outlet 142 is about 10-20 mm.

Figures 3 to 19 The window 324 is formed or disposed at one or both sides of the holder 30 in the width direction of the holder 30; the window 324 extends from the side surface of the holder 30 in the width direction to the receiving cavity 331. The window 324 is in communication with the receiving cavity 331 and the atomization chamber 530. In use, as shown by arrow R2 in FIG. 9, the window 324 provides a path for the aerosol of the atomization chamber 530 to bypass the receiving cavity 331 and / or the atomization assembly 50 to be output to the air outlet tube 123.​​

[0240] Accordingly, according to Figure 15 As shown, the first sealing portion 41 is arranged with:

[0241] An avoidance opening 413 is formed or located on the sidewall of the first sealing portion 41. When the atomization assembly 50 is accommodated or located within the first sealing portion 41, the second surface 520 and / or the atomization chamber 530 is in communication with the window 324 through the avoidance opening 413.

[0242] In particular, according to Figures 11 to 16 As shown, the 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.

[0243] According to Figures 11 to 16 As shown, the aerosol output passage comprises:

[0244] A first aerosol output passage R21 providing a first passage path for delivering aerosol to the first air outlet 141;

[0245] A second aerosol output passage R22 providing a second passage path for delivering aerosol to the second air outlet 142.

[0246] In embodiments, the first aerosol output passage R21 and the second aerosol output passage R22 are for delivering aerosol generated by the same atomization assembly 50 to the first air outlet 141 and the second air outlet 142, respectively; rather than delivering aerosol generated by two different atomization assemblies 50 to the first air outlet 141 and the second air outlet 142, respectively.

[0247] In particular, according to Figures 3 to 10 As shown, the first aerosol output passage R21 and the second aerosol output passage R22 are at least partially formed or defined between the first housing 12 and the cap 11. For example, the first aerosol output passage R21 and the second aerosol output passage R22 comprise a slit or gap formed or located between the first housing 12 and the cap 11.

[0248] In particular, according to Figures 3 to 10 As shown, the first aerosol output passage R21 further comprises a first tubular wall 116 formed on the cap 11; the first tubular wall 116 is arranged to extend from the first air outlet 141 towards the distal end 120. The second aerosol output passage R22 further comprises a second tubular wall 117 formed on the cap 11; the second tubular wall 117 is arranged to extend from the second air outlet 142 towards the distal end 120.

[0249] According to Figures 3 to 10As 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 a wide 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 able to be divided into two streams output via the first aerosol output channel R21 and the second aerosol output channel R22.

[0250] In embodiments, the first aerosol output channel R21 and the second aerosol output channel R22 are arranged to be mirror images of each other or symmetrically arranged. In embodiments, the first aerosol output channel R21 and the second aerosol output channel 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 aerosol output channel R21 and the second aerosol output channel R2 do not generate vortexes, which is advantageous for nasal inhalation.

[0251] Alternatively, in some other variant embodiments, the first aerosol output channel R21 and the second aerosol output channel R22 have different path lengths; the different path lengths are to form aerosol outputs in a time sequence.

[0252] 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 first aerosol output channel R21 and / or the second aerosol output channel R22 is curved between the first housing 12 and the cap 11; more preferably, the first aerosol output channel R21 and / or the second aerosol output channel R22 is curved in an arc shape between the first housing 12 and the cap 11.

[0253] 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 first aerosol output channel R21 and / or the second aerosol output channel R22 is curved between the first housing 12 and the cap 11; more preferably, the first aerosol output channel R21 and / or the second aerosol output channel R22 is curved in an arc shape between the first housing 12 and the cap 11.

[0254] According to Figures 3 to 10 As shown, the electronic atomization device further comprises:

[0255] A flexible gasket 15, made of flexible silicone or the like, provides a seal at least partially between the first housing 12 and the cap 11. The gasket 15 is annular with a perforation 151. The gasket 15 has a positioning protrusion 153; the first housing 12 has a positioning recess 127. In assembly, the positioning protrusion 153 of the gasket 15 is inserted into the positioning recess 127 of the first housing 12, so as to provide positioning in assembly of the gasket 15 and the second housing 12, and to provide retention after assembly. The perforation 151 of the 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 split into two paths after passing through the perforation 151 of the gasket 15, and is 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 gasket 15.

[0256] In particular, according to Figures 3 to 10 as shown, the flexible gasket 15 is arranged with a protrusion 152 on the surface facing the cap 11; the protrusion 152 is a closed annular around the perforation 151.

[0257] According to Figures 3 to 10 as shown, the gasket 15 is arranged substantially perpendicular to the longitudinal direction of the electronic atomization device. In embodiments, the flexible gasket 15 is arc-shaped, or curved. In particular in Figures 3 to 10 , the gasket 15 is curved towards the distal end 120.

[0258] In embodiments, the first aerosol output channel R21 and the second aerosol output channel R22 are not completely separate or independent, or parts of the first aerosol output channel R21 and the second aerosol output channel R22 are shared; for example, the first aerosol output channel R21 is shared in the path portion between the atomization chamber 530 and the gasket 15. And,

[0259] Or in embodiments, the portion of the first aerosol output channel R21 between the gasket 15 and the first air outlet 141 is separate or independent from the portion of the second aerosol output channel R22 between the gasket 15 and the first air outlet 141.

[0260] In embodiments, both the first aerosol output channel R21 and the second aerosol output channel R22 bypass the recessed structure 143.

[0261] According to Figures 3 to 10 as shown, the electronic atomization device can include:

[0262] The airflow passage includes the above-mentioned air inlet passage extending from the air inlet 133 to the atomization chamber 530, and the aerosol outlet passage extending from the atomization chamber 530 to the first air outlet 141 and the second air outlet 142.

[0263] In an embodiment, the airflow passage 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 portion of the airflow passage passing through the electronic chamber 131 is independently defined by the air inlet tube 74 of the base 70, and thus is isolated from the electronic chamber 131. In addition, the two ends of the first communication hole 743 are respectively plugged and closed by the flexible first plug 75 and the second plug 76, and thus are isolated from the electronic chamber 131.

[0264] In an embodiment, all the paths through which the complete airflow passage flows are sealed; in particular, all the rigid components through which the complete airflow passage flows are plugged or sealed by flexible sealing elements or sealing materials. For example, the first sealing element 20, the second sealing element 40, the first plug 75 and the second plug 76, the sealing gasket 15, etc., all provide sealing between the components through which the airflow passage passes, which is advantageous for preventing seepage.

[0265] According to Figures 3 to 19 As shown, the outer side surface of the holder 30 is further provided with:

[0266] At least one or more capillary grooves 320; the capillary grooves 320 are arranged in circumferential extension of the holder 30. The capillary grooves 320 can generally have a width and / or depth of 0.5mm-2.0mm. Adjacent capillary grooves 320 are also in communication with each other.

[0267] In an embodiment, the capillary grooves 320 are in communication with the window 324; thus, in use, the capillary grooves 320 can adsorb the aerosol condensate generated in the window 324 by capillary action.

[0268] According to Figures 3 to 19 As shown by the arrow R3, the electronic atomization device further comprises:

[0269] The air exchange passage is in communication between the atomization chamber 530 / retention recess 711 and the liquid storage chamber 121, for adjusting the pressure in the liquid storage chamber 121.

[0270] According to Figures 3 to 19 As shown, the air exchange passage comprises:

[0271] The first air exchange groove 714 is formed on the surface of the base 710 facing the proximal end 110. The first end of the first air exchange groove 714 is connected to the retention recess 711 and thus in air communication, and the second end is in air communication with the cavity 334 of the holder 30.

[0272] Specifically after assembly, a portion of the first air exchange slot 714 proximate to the first end is covered by the second sealing portion 42 of the second sealing element 40; and, a portion of the first air exchange slot 714 proximate to the second end is uncovered and exposed, thereby in air communication with the cavity 334.

[0273] According to Figures 3 to 19 As shown, the air exchange passage further comprises:

[0274] An air exchange hole 321 is formed through the inner surface of the cavity 334 to the at least one capillary groove 320, thereby connecting the cavity 334 with the at least one capillary groove 320.

[0275] According to Figures 3 to 19 As shown, the air exchange passage further comprises:

[0276] At least one second air exchange slot 34 is formed or arranged on the holder 30; specifically, the second air exchange slot 34 is formed or arranged on the outer surface of the holder 30. The second air exchange slot 34 is in communication between the liquid delivery passage 311 and the at least one capillary groove 320, to provide communication between the liquid delivery passage 311 and the at least one capillary groove 320.

[0277] According to Figures 3 to 19 As shown, the second air exchange slot 34 extends from the surface of the holder 30 towards the proximal end 110 to the peripheral surface of the holder 30.

[0278] In embodiments, the complete air exchange passage is defined by the first air exchange slot 714, the air exchange hole 321, the at least one capillary groove 320 and the second air exchange slot 34. Specifically according to Figures 3 to 19 As shown by the arrow R3 in FIG. 11, when the negative pressure in the reservoir cavity 121 exceeds a predetermined threshold, the air in the aerosolization chamber 530 / retention cavity 711 sequentially passes through the first air exchange slot 714, the air exchange hole 321, the at least one capillary groove 320 and the second air exchange slot 34 into the reservoir cavity 121, thereby relieving the negative pressure in the reservoir cavity 121. When the over-saturated liquid substrate is injected into the reservoir cavity 121 during production preparation or in use when the pressure in the reservoir cavity 121 is greater than the external pressure, the liquid substrate in the reservoir cavity 121 will seep outwardly through the air exchange passage in the direction shown by the arrow R3 to balance the pressure difference between the reservoir cavity 121 and the external pressure.

[0279] 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. And, a portion of the passage path of the air exchange passage is defined by the at least one capillary groove 320.

[0280] In embodiments, the venting passage is at least partially formed between the carrier 30 and the first sealing element 20. For example, in embodiments, the second venting groove 34 defines a passage path of the venting passage between the carrier 30 and the first sealing element 20.

[0281] It should be noted that the above-mentioned embodiments illustrate rather than limit the application, and that those skilled in the art will be able to design many alternative embodiments without departing from the scope of the appended claims. The word "comprising" does not exclude the presence of elements or steps other than those listed in a claim.
