The atomizing device 1 includes a housing 11 and a bottom cover 12, the housing 11 includes an upper portion and a lower portion, the upper portion is a suction nozzle 111, and the lower portion is a mounting portion 112. The suction nozzle 111 is a liquefied aerosol outlet, which can be used for the user to directly suck through the mouth and the nose, or other suction devices can be used for suction. The mounting portion 112 is used to connect with a battery rod (not shown).

In this example, the atomizer 1 is inserted into the battery rod, so that the outer diameter of the mounting portion 112 is slightly smaller than the joint between the upper and lower portions. Preferably, the upper and lower part of shell 11 combines the department and sets up sealing washer 113, makes to form airtight between atomizing device 1 and the battery pole to avoid leaking gas, ensure that the air that external replenishment was advanced can fully fuse with the atomizing liquid after the atomizing, avoid the seam leak gas to bring the problem that howling sound and pneumatic switch are insensitive, also stabilized atomizing device and battery pole be connected simultaneously, avoid appearing atomizing device's rocking after the installation. The housing 11 and the bottom cover 12 define an internal cavity enclosing the atomizing core, the reservoir, the air passage, etc. The portions are explained below with reference to fig. 2.

The cavity comprises an air passage 13, the upper part of the air passage 13 is communicated with the suction nozzle, and a liquid storage bin 14 is formed between the outer wall of the air passage 13 and the shell 11 and used for storing atomized liquid. The atomizing core support 3 is arranged below the air passage 13, the atomizing core support 3 is arranged in a shape like a Chinese character 'tu', the top of the shape like the Chinese character 'tu' is provided with an opening 31 which is communicated with the air passage 13 and forms airtight connection, for example: the upper part of the bracket 3 is provided with a silica gel pad which is in interference contact with the lower part of the air passage 13 to form air tightness. The below of support 3 sets up atomizing core mounting groove for hold atomizing core subassembly 4. The shoulder of the convex bracket 3 forms an atomized liquid channel inlet 32 which is communicated with the atomized liquid core assembly 4, so that the atomized liquid in the liquid storage bin 14 can directly reach the atomized liquid core 4. Because the main components of the atomized liquid are PG (propylene glycol) and VG (vegetable glycerin), the atomized liquid has considerable viscosity, and the atomizing core support 3 is designed to be in a convex shape, so that compared with the common flat-top design, the atomized liquid passage inlet is enlarged, the atomized liquid passage is shortened, the passability of the atomized liquid is enhanced, and the problem of insufficient liquid supply is solved.

Preferably, the inner wall of the housing 11 is configured to be smaller at the top and larger at the bottom, and the inner diameter of the housing above the dividing surface 114 is smaller than that below, which can provide guidance for the assembly of the atomizing core holder 3 and the bottom cap 12, and is easier to assemble and also more favorable for the sealing member to form a seal. Referring to fig. 3, the atomizing core assembly 4 of the present invention comprises: the atomizing device comprises a sealing sleeve 41, a flow stabilizing cotton 43 and a heating element 44, wherein the heating element 44 is arranged below the flow stabilizing cotton 43 and is in contact with and in interference fit with the flow stabilizing cotton 43 so as to heat the atomized liquid in the flow stabilizing cotton 43 and atomize the atomized liquid.

The electrode 5 is mounted on the bottom cover 12, and the structure and assembly relationship of the two are shown in detail in fig. 4. Fig. 4 is an exploded cross-sectional view of the bottom cover 12, the electrode 5 and related components.

In order to make the atomizing core holder more stable, a fastening hole 123 may be provided above the side wall of the bottom cover 12, and can be engaged with a fastening hole 3b2 (see fig. 6) on the atomizing core holder 3 after installation. The electrode 5 is a crown spring terminal, the terminal 5 includes a cavity 51 therein, the cavity 51 includes a crown spring 52 therein, and the crown spring 52 protrudes inward and can elastically deform outward.

The condensate absorption cotton 6 is used for absorbing the condensed aerosol and water vapor. The side wall of the bottom cover 12 includes a groove 122 for mounting the packing 121. The sealing ring 121 is in interference fit with the inner surface of the mounting portion 112 to form a seal, so that the atomized liquid and the condensate are further prevented from leaking. An air inlet 127 is arranged below the bottom cover 12, when the suction nozzle generates negative pressure due to suction, the outside air enters the atomizing device from the negative pressure, is mixed with aerosol generated after atomization, and is discharged out of the atomizing device through the air passage 13 and the suction nozzle. The air inlet 127 is provided below the bottom cover 12, which makes the structure of the atomizer more compact and the air path more reasonable, and in embodiments where this effect is not desired, the air inlet may be provided on the housing.

In view of the fact that after the atomized liquid is reduced, it is necessary to ensure that the liquid storage bin can be timely supplemented with air, otherwise, the negative pressure in the liquid storage bin is too high, which may affect the liquid supply, for this reason, in a more preferred embodiment of the present invention, the atomizing core support 3 is designed as a split component, as shown in fig. 5 to 7, and includes: an upper holder seal 3a, a lower holder 3 b. Please refer to fig. 6-7 for the detailed structure of the frame sealing member 3a and the frame 3 b.

Comprises a liquid inlet guide surface 3b1 which inclines downwards to facilitate the enlargement of atomized liquid channel and prevent the shortage of liquid supply.

The 'convex' shape design of the support 3B makes the aperture of the lower atomizing chamber 3B3 larger than the aperture of the top opening 31, that is, the front and/or rear of the support 3B larger than the aperture of the air passage 13 is provided with an inclined surface, so that an aerosol channel 3B5 is formed between the opening 31 and the atomizing chamber 3B3, the lower end of the aerosol channel 3B5 is large, the upper end is small, and due to the venturi effect, the flow rate of the gas in the air passage 13 is increased during suction, and the air passage forms a larger negative pressure at the air passage opening, so that the aerosol can more fully enter the air passage 13, and the generation of condensate is reduced, wherein the air passage of the aerosol during suction is shown by an arrow a in fig. 2B, and the air passage is shown by an arrow B in fig. 2B.

More preferably, the air duct 3b4 is arranged on the side wall of the bracket 3b, the upper end opening 3b5 of the air duct 3b4 is covered by the sealing gasket 3a2, and the lower end opening 3b6 is opened, so that when the atomized liquid in the liquid storage bin is reduced, air can be supplemented into the liquid storage bin in time. More preferably, the air passage 3b4 is configured to be a zigzag shape, which increases the length of the air passage 3b4 and narrows the aperture of the air passage, so that even if a small amount of atomized liquid leaks into the air passage from the opening 3b5, the atomized liquid cannot flow out of the air passage due to the viscosity of the atomized liquid, and the leakage of the atomized liquid is avoided.

In conclusion, the atomizing device provided by the utility model has the advantages that the channel for the atomized liquid to enter the atomizing core from the liquid storage bin is shorter and wider, and particularly, the atomizing core support in the preferred embodiment is designed, so that the atomized liquid can easily reach the steady flow cotton, the air in the liquid storage bin can be timely supplemented, and the problem of insufficient liquid supply is avoided. The design that the cotton was absorbed in sealing member and condensation on the atomized liquid passageway has avoided the leakage of atomized liquid, and gas circuit reasonable in design simultaneously for the aerosol after the atomizing can be abundant with the air mixing, has promoted the result of use.
