The present application is described in detail below with reference to the accompanying drawings and examples.

Referring to fig. 1 to 7, in the present embodiment, an atomizer and an electronic atomization device are provided, and the electronic atomization device can be applied to the technical fields of medical treatment, beauty treatment, electronic cigarette, and the like, and is used for heating an aerosol generating substrate to form an aerosol when being electrified. The aerosol-generating substrate may be a liquid formulation, a tobacco tar, or any other liquid suitable for electronic atomization, wherein the drug is dispersed in a liquid solvent. Specifically, the atomizer may include an atomizing core 7 and a base 4.

As shown in fig. 1 to 4, an atomizing chamber 14 is formed between the atomizing core 7 and the base 4, wherein the atomizing core 7 is used for heating an aerosol-generating substrate, the aerosol-generating substrate is atomized in the atomizing chamber 14 to form aerosol, an air inlet hole 9 is arranged on the base 4, external air enters the atomizing chamber 14 through the air inlet hole 9, and the aerosol in the atomizing chamber 14 is taken out to be sucked by a user.

Specifically, be provided with atomizing core 7 and base 4 in the atomizer, be formed with atomizing chamber 14 between atomizing core 7 and the base 4, atomizing core 7 is arranged in atomizing aerosol generation matrix in order to produce the aerosol, the aerosol is filled in atomizing chamber 14, be provided with inlet port 9 on base 4, inlet port 9 runs through base 4, the air inlet and the external gas intercommunication of inlet port 9, the gas outlet intercommunication atomizing chamber 14 of inlet port 9, when electronic atomizing device carries out work, external gas enters into inlet port 9 through the air inlet, and enter into atomizing chamber 14 through the gas outlet, take out the aerosol in the atomizing chamber 14 outwards, for the user to inhale. Because the air outlet of the air inlet hole 9 is closer to the atomization core 7, when the atomization core 7 atomizes the aerosol generating substrate to generate aerosol, the atomization core 7 can emit radiant heat outwards, and the radiant heat can lead the air outlet of the air inlet hole 9 to be fused so as to block the hole, so that external air cannot enter the atomization cavity 14, and the aerosol in the atomization cavity 14 is taken out outwards. In order to effectively solve the above-mentioned problem, in this application, the inlet port 9 on the base 4 is set to the first air inlet section 91 and the second air inlet section 92, the cross-sectional area of the second air inlet section 92 is greater than that of the first air inlet section 91, the first air inlet section 91 and the second air inlet section 92 are communicated, and the second air inlet section 92 is located between the first air inlet section 91 and the atomizing cavity 14, one end of the second air inlet section 92 is close to the atomizing cavity 14, namely close to the atomizing core 7, and after the external air enters the second air inlet section 92 through the first air inlet section 91, the external air enters the atomizing cavity 14 from the second air inlet section 92 to carry out aerosol.

When the user uses the electronic atomization device for a long time, the second air inlet section 92 is deformed by heat and even is partially melted, and the cross section area of the second air inlet section 92 is larger than that of the first air inlet section 91, so that when the second air inlet section 92 is deformed due to the radiation heat of the atomization core 7, the second air inlet section 92 not only has a larger deformation space, but also can store a part of molten material, and the deformation of the second air inlet section 92 is prevented from affecting the air inlet effect of the first air inlet section 91. Meanwhile, the inner wall of the first air inlet section 91 has a supporting effect on the second air inlet section 92, so that the air inlet hole 9 is not easily blocked by molten materials due to deformation, the air inlet effect is further improved, and meanwhile, part of energy can be taken away by air flow, so that the phenomenon of burning of the atomizing core 7 can be avoided, and aerosol in the atomizing cavity 14 can be discharged outwards for a user to inhale. Therefore, in this application, need not to add a metal cover or other heat-resistant material in the gas outlet department of inlet port 9, set up inlet port 9 into first section 91 and second section 92 that admits air to set up the cross-sectional area of second section 92 that admits air is greater than the cross-sectional area of first section 91 can, the operation process is comparatively simple and convenient, need not to assemble, has the advantage of being convenient for make and with low costs.

Referring to fig. 1 to 2, the first air inlet section 91 and the second air inlet section 92 on the base 4 are coaxially disposed, and meanwhile, since the cross-sectional area of the second air inlet section 92 is larger than that of the first air inlet section 91, the distance from the circumferential side wall of the first air inlet section 91 to the circumferential side wall of the second air inlet section 92 is consistent, so that no matter where the circumferential side wall of the second air inlet section 92 is deformed, the air inlet effect of the first air inlet section 91 is not affected, and the phenomenon of air flow obstruction can be further reduced. In this embodiment, the base 4 is provided with a plurality of air intake holes 9, that is, a plurality of first air intake sections 91 and second air intake sections 92, and the plurality of air intake holes 9 disposed on the base 4 are arranged at equal intervals, and the distance between the air intake holes 9 on the base 4 is not specifically limited in this application, and can be set according to practical situations.

The first air inlet section 91 and the second air inlet section 92 are coaxially arranged, so that external air can quickly enter the second air inlet section 92 after entering the first air inlet section 91 and enter the atomizing cavity 14 from the second air inlet section 92, the external air can smoothly enter the atomizing cavity 14 through the first air inlet section 91 and the second air inlet section 92, the required time is shortest, the shortage of air inflow is effectively avoided, and the radiation heat released by the atomizing core 7 can be quickly taken away along with the air flow, so that the problem that aerosol in the atomizing cavity 14 cannot be timely taken out to burn is avoided.

In the present embodiment, the center lines of the first air intake section 91 and the second air intake section 92 are arranged on the same line, and the cross-sectional area of the second air intake section 92 located at the upper end of the first air intake section 91 is larger than that of the first air intake section 91, so that a blocking step is formed at the junction of the first air intake section 91 and the second air intake section 92. Specifically, for example: the first air inlet section 91 and the second air inlet section 92 are both cylindrical, the radius of the first air inlet section 91 is 2cm, the radius of the second air inlet section 92 is 5cm, and as the second air inlet section 92 is arranged above the first air inlet section 91 and the circle centers of the first air inlet section 91 and the second air inlet section 92 are arranged on the same straight line, an annular ring with the radius of an inner ring of 2cm, the radius of an outer ring of 5cm and the thickness of 3cm is formed between the first air inlet section 91 and the second air inlet section 92, and the annular ring is a blocking step, so that when the inner wall of the second air inlet section 92 is deformed due to the radiation heat of the atomizing core 7, the blocking step is used for blocking and accumulating molten materials, thereby avoiding the molten materials from entering the first air inlet section 91 and causing the blocking of the air inlet hole 9 by the molten materials.

The blocking step formed by the first air inlet section 91 and the second air inlet section 92 is arranged facing the atomizing core 7, and since the atomizing core 7 atomizes the aerosol generating substrate to generate aerosol, the aerosol in the atomizing cavity 14 can be discharged outwards for a user to inhale, but a part of aerosol is not discharged outwards, aerosol condensate is formed after the inside of the second air inlet section 92 is cooled, and the generated aerosol condensate can flow downwards under the action of gravity, so that the aerosol condensate can flow into the blocking step along the inner wall of the second air inlet section 92 and adhere to the step surface, the aerosol condensate is prevented from flowing outwards from the first air inlet section 91, and since the aerosol condensate is generated after being cooled, the temperature of the aerosol condensate is lower, when the aerosol condensate adheres to the blocking step, the heat of the aerosol core 7 acting on the blocking step can be absorbed, and therefore the blocking step is not easy to deform.

Referring to fig. 1 to 2, the length of the first air inlet section 91 disposed on the base 4 is not less than the length of the second air inlet section 92, wherein the lengths of the first air inlet section 91 and the second air inlet section 92 are axial lengths, and the length of the first air inlet section 91 is greater than or equal to the length of the second air inlet section 92, for example: the second air intake section 92 has a length of 4cm, and the first air intake section 91 has a length of 4cm or more, including 4cm. Since the cross-sectional area of the first air intake section 91 is smaller than that of the second air intake section 92, the longer the length of the first air intake section 91, the better the support, so the first air intake section 91 does not need to be easily deformed; when the length of the second air intake section 92 is close to the length of the first air intake section 91, the first air intake section 91 is farther from the atomizing core 7, and the radiant heat away from the atomizing core 7 is weakened, so that the first air intake section 91 is not easily deformed; and is also provided with

The second air inlet section 92 is disposed above the first air inlet section 91, so that when the air inlet hole 9 is subjected to the radiation heat released by the atomizing core 7, the second air inlet section 92 can play a role of protecting the first air inlet section 91, so that the first air inlet section 91 is not easy to deform, and the second air inlet section 92 can be better supported.

A plurality of air inlets 9 are arranged in the extension column 10, namely, a first air inlet section 91 and a second air inlet section 92 are arranged in the extension column 10 of the seat body, the first air inlet section 91 and the second air inlet section 92 are axially extended along the extension column 10, and the air inlets 9 are positioned in the extension column 10 of the first accommodating groove 6, so that the distance from the air outlets of the air inlets 9 to the atomization core 7 is shorter than the distance from the bottom wall of the first accommodating groove 6 to the atomization core 7; it should be noted that, the air outlet of the air inlet hole 9 is the air outlet of the second air inlet section 92, so that even if the aerosol is cooled inside the first accommodating groove 6 to generate aerosol cooling liquid, the aerosol condensate inside the first accommodating groove 6 is not easy to enter the first air inlet section 91 and the second air inlet section 92, so that the aerosol condensate is effectively prevented from flowing out from the first air inlet section 91 and the second air inlet section 92, and the risk of leakage of the aerosol condensate is avoided.

Wherein, the pedestal sets up for integrated into one piece with the connected mode of base 4, and integrated into one piece sets up to mean that the connected mode between pedestal and the base 4 is the undetachable connection, for example: welding or integral casting, not specifically limited in this application, wherein, the connection of extension post 10 and pedestal on the pedestal also sets up for integrated into one piece, and a cross-sectional area of extension post 10 towards atomizing core 7 one end is less than the cross-sectional area of extension post 10 back to atomizing core 7 one end, and extension post 10 wholly presents the tower shape promptly, and extension post 10 is towards atomizing core 7's one end terminal surface just is the extension post 10 upper end that is provided with the second air inlet section 92 gas outlet, and extension post 10 back to atomizing core 7's one end just is the extension post 10 lower extreme that is provided with first air inlet section 91 gas inlet.

One end of the air inlet groove 11 is communicated with the outside atmosphere, the other end of the air inlet groove 11 is connected with air inlets of the first air inlet sections 91, and the air inlets of the first air inlet sections 91 are located at the groove wall of the air inlet groove 11 facing the atomizing core 7, so that the sum of the cross sectional areas of the first air inlet sections 91 is smaller than the cross sectional area of the air inlet groove 11, and external air enters the atomizing cavity 14 through the air inlet groove 11, the first air inlet sections 91 and the second air inlet sections 92 and discharges aerosol in the atomizing cavity 14 outwards. By arranging the air inlet groove 11, enough air inflow can be ensured, so that external air enters the first air inlet section 91 and the second air inlet section 92 through the air inlet groove 11, and the air entering the first air inlet section 91 and the second air inlet section 92 is not easy to be blocked due to the enough air inflow, so that the air entering the atomizing cavity 14 is ensured to be stable, and the user can feel smoother when sucking aerogel, and the experience of the user is improved; the sufficient air inflow takes away the aerosol in the atomizing cavity and then takes away the radiation heat, so that the end part of the extension column 10 provided with the air inlet hole 9 can be cooled, and the phenomenon that the second air inlet section 92 and the first air inlet section 91 are scalded and melted is reduced.

Referring to fig. 5 to 6, in another embodiment, in order to prevent the air inlet 9 from being deformed inwardly of the air inlet 9 by the influence of the radiant heat, a groove 16 surrounding the outer sidewall of the extension column 10 is provided on the outer circumferential surface of one end of the extension column 10 provided with the air inlet 9, so that when the atomization core 7 performs atomization on the aerosol-generating substrate, the heat emitted from the extension column 10 provided with the air inlet 9 acts on the end surface of the atomization core 7, and at this time, the material of the end surface is softened first, and then is inclined or collapsed to the outside of the air inlet 9 through the space of the groove 16, thereby reducing the flow of molten material into the air inlet 9, avoiding the air inlet 9 from being blocked, and ensuring that external gas can smoothly enter the atomization cavity 14.

Wherein, in order to further reduce the radiant heat applied to the extension column 10, a silica gel ring is provided on the groove 16 on the outer circumferential surface of the extension column 10, and the silica gel ring is detachably mounted on the groove 16, so that when the external heat is applied to the extension column 10, part of the heat can be absorbed through the silica gel ring, thereby effectively reducing the deformation of the extension column 10 due to the heating, thereby ensuring the smoothness of the air inlet 9 inside the extension column 10, so that the external air enters the atomizing cavity 14 after passing through the air inlet groove 11, the first air inlet section 91 and the second air inlet section 92, and the aerosol in the atomizing cavity 14 is carried outwards and enters the oral cavity of a user from the air outlet channel 12.

Because the second air inlet section 92 is relatively close to the atomizing core 7, when the atomizing core 7 works, the radiated heat firstly acts on the second air inlet section 92, the second air inlet section 92 is easier to deform or melt, so that the length of the second air inlet section 92 is set to be larger than that of the first air inlet section 91, the accommodating space of the second air inlet section 92 is relatively larger, more air can be accommodated, after the heat enters the second air inlet section 92, the heat reaches the first air inlet section 91 after a period of time, and therefore the heat is in a decreasing state, and meanwhile, the heat is absorbed in the second air inlet section 92, so that the heat is reduced to be transferred to the first air inlet section 91, the first air inlet section 91 is prevented from being melted and blocked, and the sufficient amount of external air is ensured to flow into the atomizing cavity 14 through the first air inlet section 91 and the second air inlet section 92.

Referring to fig. 9 to 10, in another embodiment, the first air inlet section 91 and the second air inlet section 92 inside the extension column 10 are configured in another optimized structure, specifically, the second air inlet section 92 inside the extension column 10 is provided with an air outlet area, the air outlet area includes a plurality of first air inlet sections 91, the plurality of first air inlet sections 91 are communicated with the second air inlet section 92, external air enters through the air inlet groove 11 and enters into the air outlet area of the second air inlet section 92 from the plurality of first air inlet sections 91, and finally enters into the atomizing cavity 14 from the air outlet area, wherein the inner shape of the second air inlet section 92 is configured in a conical shape, that is, the end with a larger cross-sectional area faces the atomizing cavity 14, the end with a smaller cross-sectional area faces the plurality of first air inlet sections 91, the inner part of the second air inlet section 92 forms a larger air outlet area, when the end with a larger cross-sectional area of the second air inlet section 92 melts, the molten material flows obliquely toward the outer wall of the extension column 10, and the air outlet area can also be contained, so that the first air inlet section 91 of the second air inlet section 92 can be further prevented from blocking; more air can also be contained in this air outlet region so that the first air inlet section 91 is farther from the atomizing core 7. The heat that the atomizing core 7 during operation sent can be consumed a large amount of heat by second air inlet section 92 when passing through second air inlet section 92, only little partial heat is used in first air inlet section 91 to the effectual influence that avoids the heat to cause first air inlet section 91 prevents that first air inlet section 91 from being melted and changing the resistance of inhaling, makes outside gas can enter into atomizing chamber 14 smoothly, and outwards brings the aerosol in the atomizing chamber 14 to user's oral cavity, effectually promotes user's use experience.
