Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure generally relate to the field of atomizers, and in particular, to an atomization device. BACKGROUND

[0002] In an atomization device, an atomization core converts an atomization substrate into a usable state by heating. In a conventional atomization device, the atomization core, by virtue of its internal porous structure, is able to store a certain amount of atomization substrate, which can ensure the smooth progress of the atomization process. However, these atomization cores are relatively large in volume and thickness, which is not conducive to the miniaturization of the atomization device and the saving of space. When thinner atomization cores are used, their porous structure is weakened in its ability to store atomization substrate, and the longer oil supply path can not be able to provide atomization substrate in time for the atomization surface of the atomization core, which can cause problems such as dry burning or interruption of the atomization film.

[0031] Preferred embodiments of the present disclosure will be described in greater detail below, with reference to the accompanying drawings. While preferred embodiments of the present disclosure are shown in the drawings, it is understood that the present disclosure can be embodied in various forms without being limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0032] The term "includes" and its variants are meant to cover non-exclusive inclusions, i.e., that the listed items are included, but other items are not precluded. The term "or" is meant to be inclusive, i.e., to include the possibility that a selection of one or more of the listed items is made. The term "based on" is meant to be "based, at least in part, on."

The term "another embodiment" is meant to be at least one, but not necessarily two, additional embodiments. The terms "first," "second," etc. can refer to different or the same objects.

[0033] As described above, in a conventional atomization device, the atomization core can store a certain amount of atomization substrate by virtue of its internal porous structure, which can ensure the smooth progress of the atomization process. However, these atomization cores are relatively large in volume and thickness, which is not conducive to the miniaturization and space saving of the atomization device. When thinner atomization cores are used, the ability of their porous structure to store atomization substrate is weakened, and the longer oil supply path can not be able to provide atomization substrate in time for the atomization surface of the atomization core, which can cause dry burning or atomization film interruption problems.

[0034] Embodiments of the present disclosure provide an atomization device. The atomization device includes a body, a bracket, and a heating assembly. The body includes an air suction channel and an oil tank. The air suction channel is formed inside the body, and the air suction channel includes an air suction port arranged at the top of the body and an air exhaust port arranged at the bottom of the air suction channel. The oil tank is arranged on one side of the air suction channel in the radial direction, and an end of the oil tank away from the air suction port is provided with an opening. The bracket is coupled to the end of the body away from the air suction port. The bracket includes a positioning slot that penetrates through the bracket and corresponds to the opening. The heating assembly is arranged in the positioning slot along an arrangement direction. The heating assembly includes a suction side and an atomization side. The suction side faces the opening of the oil tank to receive the atomization substrate in the oil tank. The atomization side defines an atomization cavity that communicates with the air exhaust port. In this way, the heating assembly is mounted on the bracket at the bottom of the oil tank, and the heating assembly is soaked in the atomization substrate in the oil tank, which shortens the oil supply path between the oil tank and the heating assembly. The oil tank can sufficiently supply the heating assembly with atomization substrate, thereby avoiding dry burning or film interruption problems of the heating assembly. The principles of the present disclosure will be described in detail below with reference to Figures 1 to 12

[0035] Figures 1 to 6 a schematic diagram of an atomization device of a first embodiment of the present disclosure is shown, Figures 7 to 8 a schematic diagram of an atomization device of a second embodiment of the present disclosure is shown, Figures 9 to 12 a schematic diagram of an atomization device of a third embodiment of the present disclosure is shown. First, Figures 1 to 6 the specific structure of the atomization device of the first embodiment of the present disclosure and its working principle are described.

[0036] As Figures 1 to 5 ​As shown, the atomization device includes a body 10, a bracket 17 and a heating assembly 20. The body 10 forms an accommodation space inside and can support other functional components. The body 10 is internally formed with an air suction channel 14. The air suction channel 14 includes an air suction port 12 arranged at the top of the body 10 and an air exhaust port 11 arranged at the bottom of the air suction channel 14. The air exhaust port 11 and the air suction port 12 are arranged at opposite positions and can achieve air circulation. When a user inhales through the air suction port 12, atomized vapor and external air can enter the air suction channel 14 from the air exhaust port 11 and then be discharged from the air suction port 12.

[0037] As shown, Figure 1 An oil tank 13 is arranged inside the body 10 and is used to store atomization substrate. The oil tank 13 is arranged on one side of the air suction channel 14 in the radial direction, and an end of the oil tank 13 away from the air suction port 12 is provided with an opening 130. The opening 130 penetrates the inner and outer walls of the oil tank 13 and can allow the atomization substrate in the oil tank 13 to flow to the heating assembly 20, ensuring the efficiency of oil supply. In this way, the oil tank 13 can supply sufficient atomization substrate to the heating assembly 20, avoiding the problems of dry burning or film breakage caused by insufficient oil supply.

[0038] As shown, Figure 1 The bracket 17 is coupled to an end of the body 10 away from the air suction port 12. The bracket 17 includes a positioning groove 170. The positioning groove 170 penetrates the bracket 17 and corresponds to the opening 130.

[0039] As shown, Figure 1 , Figure 2 and Figure 5 The heating assembly 20 is arranged in the positioning groove 170 along the arrangement direction Y and can convert the atomization substrate in the oil tank 13 into vapor. The heating assembly 20 includes a suction side 201 and an atomization side 202. The suction side 201 faces the opening 130 of the oil tank 13 and can directly contact and receive the atomization substrate in the oil tank 13. In this way, the heating assembly 20 can always be soaked in the atomization substrate, thereby shortening the oil supply path and improving the oil supply efficiency. Since the heating assembly 20 is installed at the end of the oil tank 13, it can fully utilize the atomization substrate in the oil tank 13 and ensure sufficient oil supply each time.

[0040] The atomization side 202 of the heating assembly 20 defines an atomization cavity 15, which communicates with the air suction channel 14 and the air exhaust port 11. When the heating assembly 20 is working, the heated atomization substrate forms vapor in the atomization cavity 15, which can promote the mixing of vapor and air. In the atomization cavity 15, the vapor can be more uniformly distributed in the inhaled air, thereby improving the inhalation experience of the user. In addition, the atomization cavity 15 communicates with the air suction channel 14 and the air exhaust port 11, which can make the airflow flow smoothly.

[0041] In this way, the heating assembly 20 is installed at the end of the oil tank 13 far from the suction port 12, and the heating assembly 20 can be soaked in the atomized substrate in the oil tank 13, shortening the oil supply path between the oil tank 13 and the heating assembly 20. The oil tank 13 can fully supply the heating assembly 20 with the atomized substrate, thereby avoiding the problem of dry burning or film breakage of the heating assembly 20.

[0042] In some embodiments, as shown in Figure 1 , Figure 2 and Figure 5 , the end of the oil tank 13 close to the opening 130 is provided with a funnel-shaped inclined surface 16 to guide the flow of the atomized substrate in the oil tank 13 to the suction side 201.

[0043] As shown in Figure 1 , Figure 2 and Figure 5 , the funnel-shaped inclined surface 16 gradually shrinks from the inner wall of the oil tank 13 to the center, thereby forming an inclined flow channel. When the atomized substrate in the oil tank 13 flows under the action of gravity, the inclined surface 16 can concentrate and guide the atomized substrate to the suction side 201. In this way, not only the distance between the oil tank 13 and the heating assembly 20 is shortened, but also the resistance of the atomized substrate during flow is reduced, avoiding the problem of insufficient oil supply or flow breakage. In addition, the funnel-shaped inclined surface 16 can also prevent the atomized substrate from accumulating at the bottom of the oil tank 13, and the atomized substrate in the entire oil tank 13 can be fully utilized, thereby prolonging the service life of the atomization device.

[0044] In some embodiments, as shown in Figure 1 and Figure 5 , the atomization device further comprises a base 30. The base 30 is arranged on the side of the heating assembly 20 away from the oil tank 13 and coupled to the body 10. The base 30 is spaced apart from the atomization side 202, and a atomization cavity 15 is formed therebetween. The base 30 comprises an air inlet 31. In this way, external air can enter the atomization cavity 15 along the air inlet 31 and mix with the vapor in the atomization cavity 15.

[0045] In some embodiments, as shown in Figure 1 and Figure 5 , the arrangement direction Y of the heating assembly 20 is perpendicular to the extension direction X of the body 10. In this way, the heating assembly 20 is transversely arranged at the bottom of the oil tank 13, and the suction side 201 of the heating assembly 20 is parallel to the bottom of the oil tank 13, which can expand the contact area between the heating assembly 20 and the atomized substrate. When the oil tank 13 is filled with atomized substrate, the liquid can cover the entire surface of the heating assembly 20 under the action of gravity, and this uniform distribution not only can improve the heating efficiency of the heating assembly 20, but also can avoid the problem of local overheating or uneven heating.

[0046] In some embodiments, such as Figure 1 and Figure 5 As shown, the opening direction Z of the air inlet 31 is parallel to the arrangement direction Y. When external air enters the main body 10 through the air inlet 31, since the airflow direction inside the air inlet 31 is perpendicular to the arrangement direction Y of the heating component 20, the air can directly reach the atomizing chamber 15 via the shortest path. After entering the atomizing chamber 15, the air quickly mixes with the vapor atomized by the heating component 20 to form an aerosol. In this way, the user's inhalation experience can be improved.

[0047] In some embodiments, the position of the air inlet 31 corresponds to the position of the heating component 20, which can further enhance the mixing effect of aerosol and air.

[0048] In some embodiments, such as Figure 3 As shown, the heating assembly 20 includes a heating element 21 and a flow stabilizer 22. The heating element 21 is disposed within the positioning groove 170, located at the bottom of the oil tank 13 near the atomizing matrix. This arrangement allows the heating element 21 to be directly immersed in the atomizing matrix, thereby shortening the oil supply path and improving oil supply efficiency. The heating element 21 can be a metal component or a non-metallic component coated with a thin metal film, which can atomize the atomizing matrix when conductive.

[0049] As an example, heating element 21 can be a thinner heating element, such as a porous glass heating element. Porous glass heating elements have the advantages of efficient heat conduction, uniform heating and corrosion resistance. They can rapidly heat up in a short time to quickly heat the atomizing matrix to the temperature required for atomization. In addition, the porous structure helps to distribute heat evenly, avoids local overheating, and improves the uniformity and quality of atomization.

[0050] When the heating element 21 conducts electricity, the temperature of the heating element 21 rises rapidly. The high temperature of the heating element 21 can instantly heat the contacting atomized matrix and convert it into an aerosol.

[0051] It should be understood that in other embodiments, the heating element 21 may also be other metal parts or non-metal parts coated with a metal film, which can atomize the atomizing matrix when conducting electricity. This disclosure is not intended to limit this.

[0052] like Figure 3 As shown, the flow stabilizer 22 is disposed in the positioning groove 170 and located on the side of the heating element 21 near the opening 130. The function of the flow stabilizer 22 is to evenly distribute the atomizing matrix in the oil tank 13 to the surface of the heating element 21, which can improve the atomization effect of the heating element 21 and thus avoid the problem of dry burning caused by uneven oil supply.

[0053] As an example, the flow stabilizer 22 can be made of flow-stabilizing cotton. The flow-stabilizing cotton is a material with a flocculent structure. The flow-stabilizing cotton has the ability to adsorb liquid, can absorb the atomization matrix in the oil tank 13, and guide it to the surface of the heating element 21. In this way, the atomization matrix can be evenly distributed on the heating element 21, avoiding problems such as local accumulation or poor flow, and preventing local overheating of the heating element 21.

[0054] It should be understood that in other embodiments, the flow stabilizer 22 can also be other flocculent structures, such as wire meshes, etc. The mesh structure of the wire mesh helps to evenly distribute the atomization matrix. The present disclosure is not intended to limit the specific material.

[0055] In some embodiments, as Figure 3 shown, the heating assembly 20 further includes a gasket 24. The gasket 24 is disposed in the positioning groove 170 and on the side of the flow stabilizer 22 away from the heating element 21. In this way, the gasket 24 can prevent the atomization matrix in the oil tank 13 from leaking along the gap between the positioning groove 170 and the heating assembly 20, ensuring the sealing performance of the device. In addition, the gasket 24 can also maintain the stability of the internal pressure of the oil tank 13, so that the atomization matrix flows stably to the heating assembly 20.

[0056] In some embodiments, as Figure 3 shown, the heating assembly 20 further includes a support pad 23. The support pad 23 is disposed between the gasket 24 and the flow stabilizer 22. As an example, the support pad 23 is composed of a plurality of intersecting support bars. These support bars abut against the flow stabilizer 22, can maintain the shape of the flow stabilizer 22, and avoid the phenomenon of swelling and deformation of the flow stabilizer 22 after long-term contact with the atomization matrix, so as to maintain the flow splitting effect of the flow stabilizer 22. The support pad 23 can form, for example, a "day" - shaped or "field" - shaped structure. In this way, the support pad 23 can not only provide mechanical support for the flow stabilizer 22, but also allow the atomization matrix to flow smoothly without hindering the oil supply path.

[0057] In some embodiments, as Figure 6 shown, the atomization device further includes a battery module 40. The battery module 40 is detachably coupled to the body 10, and the user can install the battery module 40 to the body 10 or remove it from the body 10. In addition, the battery module 40 is electrically connected to the heating assembly 20. The battery module 40 can provide power for the heating assembly 20 to support its efficient atomization work. Here, the electrical connection usually uses reliable electrical interfaces, such as spring pins or contact pads, which can ensure good electrical conductivity and reduce problems of poor contact caused by vibration or movement.

[0058] In some embodiments, as Figure 6As shown, a sealing ring 41 is also arranged between the battery module 40 and the body 10. The sealing ring 41 can ensure the air tightness between the two, so that air can enter the air inlet 31 according to the designed air channel, and then smoothly flow into the atomization cavity 15 and the air suction channel 14. When the user inhales, the external air can only enter through the air inlet 31, and flow along the predetermined path, fully mix with the atomization substrate in the heating assembly 20 in the atomization cavity 15, and then enter the air suction channel 14, and finally be discharged along the air suction port 12. In this way, the problem of poor air flow or poor inhalation effect caused by air leakage can be avoided.

[0059] The principle of the atomization device of the second embodiment of the present disclosure will be described in detail below in combination with Figure 7 and Figure 8 The structure of the atomization device of the second embodiment is similar to the structure of the first embodiment described in combination with Figures 1 to 6 In the following, the differences between them will be mainly described, and the same parts will not be described again.

[0060] As shown in Figure 7 and Figure 8 , the arrangement direction Y of the heating assembly 20 forms an angle less than 90° with the extension direction X of the body 10. In this way, the atomization side 202 of the heating assembly 20 forms a bevel structure between the air inlet 31 and the air suction channel 14. The bevel structure not only helps to reduce the resistance when the air flows, but also improves the smoothness and comfort when the user inhales. When the heating assembly 20 is arranged at an inclined angle, the air entering from the air inlet 31 can flow along the bevel. Compared with the vertical arrangement, the inclined structure reduces the turbulence of the air flow when entering the atomization cavity 15, thereby reducing the air flow resistance and ensuring the smooth flow of the air flow.

[0061] In order to realize the inclined arrangement of the heating assembly 20, the positioning groove 170 on the support 17 at the bottom of the oil tank 13 is also arranged correspondingly. When the heating assembly 20 is installed at the bottom of the oil tank 13, the heating assembly 20 can be placed at an inclined angle following the angle of the positioning groove 170.

[0062] In addition, when the heating assembly 20 is arranged at an inclined angle, the accumulation of air bubbles at the inhalation side 201 of the heating assembly 20 can be prevented. The inclined inhalation side 201 can promote the rapid discharge of air bubbles, avoiding the influence of air bubbles on the atomization effect.

[0063] The principle of the atomization device of the third embodiment of the present disclosure will be described in detail below in combination with Figures 9 to 12 The structure of the atomization device of the third embodiment is similar to the structure of the first embodiment described in combination with Figures 1 to 6 In the following, the differences between them will be mainly described, and the same parts will not be described again.

[0064] AsFigures 9 to 12 As shown, the atomizing device also includes a base 30. The base 30 is arranged on the side of the heating assembly 20 away from the oil tank 13 and coupled to the main body 10. The base 30 is spaced apart from the atomizing side 202, and an atomizing chamber 15 is formed between them. The base 30 includes an air inlet 31. The opening direction Z of the air inlet 31 is at a 90° angle to the arrangement direction Y of the heating assembly 20.

[0065] like Figure 9 and Figure 10 As shown, the air inlet 31 serves as the entrance for external air into the atomizing chamber 15. The air inlet 31 is directly connected to the atomizing chamber 15, allowing external air to participate in the cooling and mixing process of the steam. In the embodiments of this disclosure, the opening direction Z of the air inlet 31 is perpendicular to the arrangement direction Y of the heating component 20, that is, the opening direction Z of the air inlet 31 is parallel to the extension direction X of the body 10. This allows the air inlet 31 to be arranged on one side of the atomizing side 202 of the heating component 20, rather than directly below it. In this way, condensate can be prevented from entering the air inlet 31 under the action of gravity, thereby preventing the problem of condensate clogging the air inlet 31.

[0066] In other embodiments, the angle between the opening direction Z of the air inlet 31 and the arrangement direction Y of the heating component 20 is less than 90°, and the atomizing side 202 of the heating component 20 is separated from the air inlet 31, so that the condensate cannot directly enter the air inlet 31.

[0067] In some embodiments, such as Figure 9 As shown, the air inlet 31 and the air intake channel 14 are located on different sides of the atomizing chamber 15. When external air enters the atomizing chamber 15 through the air inlet 31, because its position is opposite to the air intake channel 14, the air must flow throughout the entire atomizing chamber 15 and pass through the aerosol area, thereby ensuring sufficient contact and mixing between the air and the aerosol. In this way, the contact time between the air and the vapor is increased, promoting uniform mixing between the two.

[0068] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the embodiments in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
