Description

Technical Field

[0001] The present invention relates to an atomization device, and more particularly to an electronic atomization device and an atomizer, an atomization component and a composite liquid absorption structure thereof. Background Art

[0002] like Figure 1 As shown, the atomization assembly 40 of the related art generally includes a liquid-absorbing cotton 412 and a heating element 42 wound around the liquid-absorbing cotton 412. When the liquid-absorbing cotton 412 absorbs liquid, an oil film A will be formed on the surface of the liquid-absorbing cotton 412. The liquid-absorbing cotton 412 expands after absorbing liquid and bulges outward significantly, thereby increasing the thickness of the oil film A on the liquid-absorbing cotton 412. The oil film A is higher than the outer surface of the heating element 42. When the user inhales, the liquid of the electronic atomization device is replenished to the liquid-absorbing cotton 412. Due to the large temperature difference between the inside and outside of the oil film A, oil frying will occur, which not only causes the components in the electronic atomization device to be contaminated, but also affects the user experience.

[0003] Currently, sintered atomizer components are widely used in electronic atomizer devices to solve the above problems. Figure 2 As shown, the atomization component 40 generally includes a hard liquid-absorbing body and a heating element 42 for absorbing the liquid. The hard liquid-absorbing body can be a sintered porous body 411. Some of the current heating elements 42 are sheet structures formed by processes such as stamping or laser cutting. The heating element 42 is arranged on a surface of the sintered porous body 411, and the heating element 42 and the sintered porous body 411 are integrally formed by sintering. Due to the surface tension of the sintered porous body 411, an oil film A will also form on the surface of the sintered porous body 411. Since the sintered porous body 411 is not easy to deform, because the thickness of the oil film A remains unchanged before and after the absorption of the liquid, and the thickness is relatively low, generally less than the thickness of the heating element 42, when the user draws, the liquid of the electronic atomization device is supplied to the sintered porous body 411, and the temperature difference between the inside and outside of the oil film A is small, and thus the oil explosion phenomenon will not occur.

[0004] However, during the sintering process, the sintered porous body 411 will evaporate the pore-forming agent and other materials during the high-temperature sintering process, and there will be a combination of reasons such as chemical reactions, which will cause the sintered porous body 411 to shrink significantly, so that it is easy for the heating element 42 on the formed sintered porous body 411 to partially warp relative to the surface of the sintered porous body 411, or there will be a gap B between the heating element 42 and the sintered porous body 411, see Figure 3 Since the raised portion of the heating element 42 or the portion with the gap B is not in contact with the sintered porous body 411, during the heating process of the heating element 42, it is difficult for the smoke liquid to reach the raised portion of the heating element 42, resulting in dry burning of the raised portion, wasting energy and generating problems such as burnt smell.

The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0060] Figure 4 and Figure 5 shows the first embodiment of the electronic atomization device of the present invention. The electronic atomization device can be applied to heating and atomizing e-liquid, and it can include an atomizer 100 and a power supply device 200; the atomizer 100 can be partially placed in the housing of the power supply device 200, and it can heat and atomize e-liquid in an energized state.

[0061] As Figure 6As shown, the atomizer 100 may include a liquid storage device 10, a lower base body 20, an upper base body 30, and an atomization component 40. The liquid storage device 10 can be used to store e-liquid for supply to the atomization component 40.

The lower base body 20 and the upper base body 30 can be placed in the liquid storage device 10 and located at the lower part of the liquid storage cavity. The lower base body 20 and the upper base body 30 can be snap-connected by setting a snap structure, which can be used to clamp and fix the atomization component 40. The atomization component 40 can be tightly clamped between the lower base body 20 and the upper base body 30, which can be used to heat the e-liquid supplied from the liquid storage cavity and atomize it into atomized vapor for the user to inhale. In some other embodiments, the upper base body 20 and the lower base body 30 can be omitted. Further, in this embodiment, the atomizer 100 may further include a first sealing sleeve 50; the first sealing sleeve 50 can be sleeved on the outer periphery of the atomization component 40. The presence of the first sealing sleeve 50 can achieve the sealing between the atomization component 40 and the lower base body 20, prevent liquid leakage, and make the positioning of the atomization component 40 more tight in the horizontal direction. Further, in this embodiment, the atomizer may further include a second sealing sleeve 60. The second sealing sleeve 60 can be sleeved on the upper base body 30, which can be a silica gel sleeve and can be used to seal the gap between the upper base body 30 and the liquid storage device 10.

[0062] As Figures 7 to 9 shown, further, in this embodiment, the atomization component 40 may include a composite liquid absorption structure 41 and a heating element 42. The composite liquid absorption structure 41 can be used to absorb and store the e-liquid in the liquid storage cavity. The heating element 42 can be disposed on the composite liquid absorption structure 41, which can heat and atomize the e-liquid on the composite liquid absorption structure 41 by heating.

[0063] Further, in this embodiment, the composite liquid absorption structure 41 may include a rigid first liquid absorbent 411 and a soft second liquid absorbent 412. The first liquid absorbent 411 and the second liquid absorbent 412 can be combined together, and both can be used to absorb e-liquid. The first liquid absorbent 411 and the second liquid absorbent 412 can be liquid-conductively connected, and the e-liquid in the second liquid absorbent 412 and the first liquid absorbent 411 can flow through each other.

[0064] Further, in this embodiment, the first liquid absorbent 411 may be in a bowl shape. It can be understood that in some other embodiments, the first liquid absorbent 411 may not be limited to a bowl shape and can be in a columnar shape or other shapes. The first liquid absorbent 411 can be a sintered porous body. Specifically, the sintered porous body is a ceramic porous body. It can be understood that in some other embodiments, the sintered porous body may not be limited to a ceramic porous body. In some other embodiments, it can be a glass porous body or a glass-ceramic porous body.

[0065] Further, in this embodiment, through holes 4111 may be provided on the first liquid absorbent 411. The through holes 4111 may be arranged longitudinally from the first liquid absorption surface 4114 through to the first atomization surface 4113. There may be one through hole 4111, which can be used for installing the second liquid absorbent 412. It can be understood that in some other embodiments, the through holes 4111 may not be limited to one and may also be multiple. In some embodiments, the first liquid absorbent 411 may include a first atomization surface 4113 and a first liquid absorption surface 4114. The first atomization surface 4113 may be provided on the end surface of the first liquid absorbent 411 opposite to the liquid storage cavity. The first atomization surface 4113 is the surface from which atomized vapor escapes. The first liquid absorption surface 4114 may be parallel to the first atomization surface 4113. The first liquid absorption surface 4114 may be in liquid conduction connection with the second liquid absorbent 412 and can absorb the smoke liquid flowing out from the second liquid absorbent 412.

[0066] Further, in this embodiment, the second liquid absorbent 412 and the first liquid absorbent 411 may be detachably connected. The second liquid absorbent 412 may be nested with the porous body 411. The second liquid absorbent 412 may be absorbent cotton. It can be understood that in some other embodiments, it may not be limited to absorbent cotton, and the second liquid absorbent may have fibrous or spongy or foamy materials. For example, fibrous materials made by spinning or extruding fibers, such as cellulose acetate, polyester or bonded polyolefins, polyethylene, polyester or polypropylene fibers, nylon fibers, glass fibers, etc. In some embodiments, the second liquid absorbent 412 may include a liquid guiding portion 4121 and a plugging portion 4122. The liquid guiding portion 4121 may cover the surface of the first liquid absorbent 411 opposite to the first atomization surface 4113, that is, it may be provided on the first liquid absorption surface 4114 and cover the first liquid absorption surface 4114. It may be in liquid conduction connection with the first liquid absorption surface 4114 and can guide the liquid in the liquid storage cavity to the first liquid absorbent 411 and the plugging portion 4122. The plugging portion 4122 may be provided on the liquid guiding portion 4121 and can be inserted into the through hole 4111. Its shape and size may be equivalent to those of the through hole 4111. In this embodiment, the plugging portion 4122 may be integrally formed with the liquid guiding portion 4121. It can not only be used for liquid absorption but also for air exchange to facilitate the flow of the smoke liquid in the liquid storage cavity to the composite liquid absorption structure 41.

[0067] Further, in the present embodiment, the second liquid absorbent 412 may include a second atomizing surface 4123 and a second liquid absorbing surface 4124. The second atomizing surface 4123 may be disposed on the end surface of the insertion portion 4122 away from the liquid guiding portion 4121, and it is available for the atomized vapor to escape. The second atomizing surface 4123 may be located in the middle of the end surface of the first liquid absorbent 411 opposite to the liquid storage cavity, and the first atomizing surface 4113 may be located on the outer periphery of the second atomizing surface 4123. In the present embodiment, the first atomizing surface 4113 and the second atomizing surface 4123 may be in liquid guiding connection, the first atomizing surface 4113 and the second atomizing surface 4123 may be in the same direction, and they may be flush and connected to each other. Understandably, in some other embodiments, they may not be limited to being in the same direction. Understandably, in some other embodiments, the first atomizing surface 4113 may also be slightly lower than the second atomizing surface 4123. The second liquid absorbing surface 4124 may be disposed on the end surface of the liquid guiding portion 4121 opposite to the insertion portion 4122, and is parallel to the second atomizing surface 4123. It is in liquid guiding connection with the liquid storage cavity and is available for the smoke liquid to enter the liquid guiding portion 4121.

[0068] Further, in the present embodiment, in the present embodiment, the heating element 42 may be disposed on the composite liquid absorbing structure 41 and is disposed along the length direction of the first liquid absorbent 411, and it is in contact with the first atomizing surface 4113 and the second atomizing surface 4123 respectively. In some embodiments, the heating element 42 may be made of stainless steel, nickel-chromium alloy, iron-chromium-aluminum alloy, titanium metal, etc.

[0069] In the present embodiment, the heating element 42 may be integrally formed with the first liquid absorbent 411. Specifically, the heating element 42 may be integrally formed with the porous body 411 by sintering. Further, taking the first liquid absorbent 411 as a ceramic porous body as an example, the first liquid absorbent 411 blank may be formed by kaolin clay mass first, then the heating element 42 may be attached to one end of the blank or buried in the blank, and then the blank is dried and sintered. Understandably, in some other embodiments, the heating element 42 and the first liquid absorbent 411 may be a split structure and are not limited to being integrally formed.

[0070] Further, in the present embodiment, the heating element 42 may include a heating portion 421. The heating portion 421 may be in a longitudinally elongated sheet shape, which may be placed on the first atomization surface 4113 and the second atomization surface 4123, and may be arranged in an S shape in the length direction. The heating portion 421 may include a plurality of straight portions 4211 and a plurality of bending portions 4212 that connect the plurality of straight portions 4211 in series. In the present embodiment, the straight portions 4211 of the heating portion 421 may lie flat on the second atomization surface 4123, and the bending portions 4212 may lie flat on the first atomization surface 4113. Each bending portion 4212 is connected to two adjacent straight portions 4211. When the second liquid absorbent 412 can fill the gap formed by sintering between the heating portion 421 and the first liquid absorbent 411, the heating portion 421 can be brought into contact with the smoke liquid, thereby preventing dry burning. It can be understood that in some other embodiments, the number of the straight portions 4211 is not limited to a plurality, and it may be two. The number of the bending portions 4212 is not limited to a plurality, and it may be one. In some other embodiments, the bending portions 4212 may be omitted. The heating portion 421 is not limited to an S shape, and it may also be set in other shapes such as a straight long strip shape, a tape measure shape, a wavy shape, a spiral shape, etc. according to needs. And in a composite liquid absorption structure 40, the number of sheet-shaped heating portions of the heating element 122 is not limited to one, and two or more may also be provided.

[0071] Further, in the present embodiment, the heating element 42 may further include a conductive connection portion 422. The conductive connection portion 422 may be two, which are respectively arranged on two opposite sides of the heating portion 421. The conductive connection portion 422 may be in a sheet shape and may be integrally formed with the heating portion 421. Specifically, the conductive connection portion 422 and the heating portion 421 may be integrally formed by casting. The conductive connection portion 422 may be arranged on the first atomization surface 4113. The conductive connection portion 422 may be electrically connected to the power supply device 200.

[0072] As Figure 10 shown, when the smoke liquid in the liquid storage cavity supplies the second liquid absorbent 412, because the deformation amount of the second liquid absorbent 412 is greater than that of the first liquid absorbent 411, the first atomization surface 4113 will protrude from the second atomization surface 4123, so as to fill the gap between the heating portion 421 and the first liquid absorbent 411, and make the thickness of the oil film formed on the second atomization surface 4123 greater than the thickness of the oil film formed on the first atomization surface 4113. The oil in the oil film on the second atomization surface 4123 will flow to the oil film on the first atomization surface 4113, thereby balancing the thickness of the oil film between the first atomization surface 4113 and the second atomization surface 4123, preventing oil explosion and preventing the heating element arranged thereon from dry burning, reducing energy waste, avoiding the generation of burnt smell, improving the liquid locking effect, the air exchange effect, and the user experience.

[0073] Figure 11 and Figure 12 shows a second embodiment of the electronic atomization device of the present invention. The difference between this embodiment and the first embodiment is that the composite liquid absorption structure 41 can be columnar, and the heating element 42 can be spiral. The first liquid absorber 411 and the second liquid absorber 412 can be columnar, and the second liquid absorber 412 can be sleeved on the outer periphery of the first liquid absorber 411. The second liquid absorption surface 4124 can be formed on the outer peripheral surface of the second liquid absorber 412.

[0074] Further, as Figures 12 to 14 shown, in this embodiment, the through hole 4111 on the composite liquid absorption structure 41 can be arranged along the axial direction, and it is a through structure at both ends, which can be used for installing the heating element 42. The inner side wall of the through hole 4111 can form a first atomization surface 4113, and a part of the heating element 42 can be in contact with the first atomization surface 4113. Through holes 4112 can be arranged on the two side walls of the through hole 4111 opposite to each other, and the through holes 4112 can be communicated with the through hole 4111.

[0075] Further, in this embodiment, the second liquid absorber 412 can include a liquid guiding part 4121 and a plugging part 4122. The liquid guiding part 4121 can be columnar and can be sleeved on the outer periphery of the first liquid absorber 411. The plugging part 4122 can be arranged on the inner side wall of the liquid guiding part 4121. There can be two of them, which are arranged corresponding to the through holes 4112, and can penetrate into the through holes 4112. The protruding end surface can form a second atomization surface 4123. A part of the heating part 421 of the heating element 42 can be in contact with the second atomization surface 4123. The conductive connection part 422 of the heating element 42 can penetrate out of the first liquid absorber 411 and the second liquid absorber 412 to be conductively connected to the power supply device 200.

[0076] Figure 15 and Figure 16 shows a third embodiment of the electronic atomization device of the present invention. The difference between this embodiment and the first embodiment is that there can be multiple through holes 4111, and the multiple through holes 4111 can be arranged at intervals and penetrate through the first liquid absorber 411 along the thickness direction of the first liquid absorber 411 respectively. The plugging parts 4122 can be multiple, which are arranged in one-to-one correspondence with the through holes 4111, and can be inserted into the through holes 4111 one by one, and each plugging part 4122 can be columnar. The cross-sectional shape and size of each plugging part 4122 are adapted to the inner shape and size of the bent part 4212 of the heating element 42.

[0077] Further, in this embodiment, the entire heating part 421 is embedded in the composite liquid absorption structure 41 in the width direction. The top surface of the heating part 421 is flush with the first atomization surface 4223. The width direction of the heating part 421 can be substantially perpendicular to the plane where the first atomization surface 4113 is located. On the one hand, it can make the flow of the smoke liquid in the first liquid absorption composite liquid absorption structure 41 more smooth. On the other hand, it is convenient for manufacturing and reduces the manufacturing cost. Moreover, embedding the entire heating part 421 in the composite liquid absorption structure 41 in the width direction can make most of the surface of the heating part 421 contact with the composite liquid absorption structure 41, thereby improving the atomization efficiency, reducing heat loss, preventing dry burning or greatly reducing the dry burning effect. It can be understood that in some other embodiments, the heating part 421 can also be partially embedded in the composite liquid absorption structure 41, and its top surface can protrude from the first atomization surface 4113. In some other embodiments, its top surface can also be lower than the first atomization surface 4113.

[0078] Further, in this embodiment, the heating part 421 is in contact with both the second liquid absorbent 412 and the first liquid absorbent 411. Specifically, the inner surface of the bending part 4212 can be in contact with the second liquid absorbent 412. The outer surface of the bending part 4212 can be in contact with the first liquid absorbent 411. When the first liquid absorbent 411 is sintered and shrunk, due to the existence of the second liquid absorbent 412, the heating part 421 can avoid dry burning caused by the inability to contact the smoke liquid due to the existence of the gap.

[0079] In this embodiment, the two conductive connection parts 422 can be columnar, which can be located at both ends of the heating part 421, and are integrally connected to both ends of the heating 421 respectively. They can penetrate through the two opposite side walls of the composite liquid absorption structure 41 respectively to be electrically connected to the power supply device 200.

[0080] It can be understood that the above embodiments only express the preferred embodiments of the present invention. The description is relatively specific and detailed, but it cannot be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, these technical features can be freely combined, and several deformations and improvements can also be made, which all belong to the protection scope of the present invention. Therefore, all equivalent transformations and modifications made to the scope of the claims of the present invention should fall within the scope covered by the claims of the present invention.
