Technical Field

The utility model relates to the technical field of electronic atomization, in particular to an atomization core, an atomizer and an electronic atomization device.

Background

The atomization process of the atomizer is generally as follows: atomized liquid flows into the region where the liquid guide body of the atomization core is connected with the heating body from the liquid storage cavity, the atomized liquid around the heating body is atomized under the heating action of the heating body to form aerosol which can be sucked by a user, when the user sucks, suction airflow is formed in the airflow channel, and the aerosol flows out of the atomizer along with the suction airflow to be sucked by the user.

In the related art, liquid-guiding cotton has good liquid-guiding performance, so the liquid-guiding cotton is widely used as liquid-guiding of an atomization core, and at present, an atomization core structure adopting the liquid-guiding cotton as the liquid-guiding is generally manufactured by adopting the following modes:

firstly, preparing a piece of cuboid-shaped sheet liquid-guiding cotton, a cylindrical atomizing core support with slits and a cylindrical heating body, wrapping the liquid-guiding cotton around the heating body in a doubling mode, so that the liquid-guiding cotton presents a cylindrical structure with a lug (the lug is formed by overlapping two ends of the liquid-guiding cotton), aligning the lug part of the liquid-guiding cotton with the slits of the atomizing core support, inserting the cylindrical main body part of the liquid-guiding cotton and the heating body into the atomizing core support along the axial direction of the atomizing core support until the bottom of the lug abuts against the bottom of the slits of the atomizing core support, and finally removing part of the lug exposed outside the atomizing core support through tools such as scissors, thereby obtaining a complete atomizing core structure adopting the liquid-guiding cotton as the liquid-guiding body.

However, the applicant has found that the following problems are generally encountered with such an atomizing core structure employing liquid-conducting cotton as the liquid-conducting material at present:

Referring to fig. 1-4, an embodiment of the present utility model provides an atomizing core.

Specifically, the atomizing core includes an atomizing core holder 100, a liquid guide 200, and a heat generating body 300.

The inside of atomizing core support 100 is equipped with mounting channel 110, and mounting channel 110 link up the both ends of atomizing core support 100 along the axial of atomizing core support 100 to, offer on the lateral wall of atomizing core support 100 and be linked together with mounting channel 110 slotting 120, along the axial of atomizing core support 100, slotting 120 extends the setting from the one end terminal surface of atomizing core support 100 to the other end terminal surface of atomizing core support 100, and slotting 120's length is less than the length of atomizing core support 100 and forms a spacing terminal surface 130.

The liquid guide body 200 is made of soft fiber materials, the liquid guide body 200 is provided with a main body part 210, a clamping part 220 and an extension part 230, the main body part 210 is arranged in a surrounding mode, the clamping part 220 is arranged on the outer peripheral side wall of the main body part 210 in a protruding mode, the extension part 230 is arranged on one end face of the main body part 210, the main body part 210 is located in the mounting channel 110, the outer peripheral side wall of the main body part 210 is in tight contact with the inner wall of the mounting channel 110, the clamping part 220 is at least partially located in the slit 120, the extension part 230 is located in the mounting channel 11, and the outer wall of the extension part 230 is at least in tight contact with the joint of the inner wall of the mounting channel 110 and the limiting end face 130.

The heating element 300 is connected to the inner wall of the main body 210.

In this embodiment, since the slit 120 extends from the one end surface of the atomizing core support 100 toward the other end surface of the atomizing core support 100 in the axial direction of the atomizing core support 100, and the length of the slit 120 in the axial direction of the atomizing core support 100 is smaller than the length of the atomizing core support 100, the slit 120 only penetrates through the one end surface of the atomizing core support 100 and does not penetrate through the other end surface of the atomizing core support 100, so that a limiting end surface 130 can be formed on the side wall of the atomizing core support 100, the limiting end surface 130 is used for limiting the bottom of the clamping portion 220 of the liquid guide 200, and the liquid guide 200 can be ensured to be installed in place when the atomizing core is mounted, specifically, when the bottom of the clamping portion 220 abuts against the limiting end surface 130 of the slit 120 in the process of inserting the liquid guide 200 into the atomizing core support, the liquid guide 200 is indicated to be installed in place, and at this time, the main body portion 210 and the extending portion 230 of the liquid guide 200 are all placed in the mounting channel 110 of the atomizing core support 100. The end face of one end of the atomizing core support 100 is an upper end face of the atomizing core support 100, and the end face of the other end of the atomizing core support 100 is a lower end face of the atomizing core support 100. Of course, in other embodiments, one end surface of the atomizing core support 100 is a lower end surface of the atomizing core support 100, and the other end surface of the atomizing core support 100 is an upper end surface of the atomizing core support 100, which is not limited herein.

When the liquid guide 200 is mounted in the mounting channel 110 of the atomizing core support 100, since the entire liquid guide 200 is made of soft fiber material, the outer peripheral side wall of the main body 210 can be tightly contacted with the inner wall of the mounting channel 110 under the action of the elastic force of the soft fiber material, and the outer wall of the extension portion 230 can be tightly contacted with at least the joint of the inner wall of the mounting channel 110 and the limiting end surface 130 under the action of the elastic force of the soft fiber material, so that no matter whether a structural gap is formed between the bottom of the clamping portion 220 and the bottom of the slot 120 (i.e. the limiting end surface 130) on the atomizing core support 100, the atomized liquid is difficult to leak from the joint of the outer wall of the main body 210 and the inner wall of the mounting channel 110 and the inner wall of the limiting end surface 130 into the space of the mounting channel 110 except the main body 210 and the extension portion 230, thereby effectively avoiding the occurrence of liquid leakage of the atomizing core.

In the present embodiment, the main body 210 of the liquid guide 200 has a tubular structure, and when the liquid guide 200 is embodied, the heating element 300 is disposed around the inner wall of the main body 210, that is, the main body 210 is wrapped around the outer periphery of the tubular heating element 300. The heating element 300 may be any one of a spiral heating wire, a cylindrical metal heating net, a cylindrical metal heating sheet, and a cylindrical conductive ceramic heating sheet, and of course, the heating element 300 may be any other heating structure capable of generating heat by energizing, so long as the atomized liquid provided by the liquid guide 200 can be heated and atomized, which is not particularly limited in this embodiment. The material of the liquid guide body 200 may be soft fiber material such as cotton fiber, non-woven fabric, blend fiber, etc., and the blend fiber may be polyester/nylon blend fabric blended from polyester and nylon, cotton/polyester blend fabric blended from cotton and nylon, cotton/nylon blend fabric blended from cotton and nylon, cotton/aramid blend fabric blended from cotton and aramid, etc., which is not particularly limited in this embodiment.

In the technical scheme provided by the utility model, through arranging the atomizing core support 100 with the mounting channel 110 and the slit 120 and the liquid guide 200 with the main body part 210, the clamping part 220 and the extension part 230, when assembling the atomizing core, the clamping part 220 positioned on the outer peripheral side wall of the main body part 210 can be aligned with the slit 120 on the atomizing core support 100 and is in close contact with the inner wall of the mounting channel 110 along the axial direction of the atomizing core support 100, the main body part 210 and the extension part 230 of the liquid guide 200 are inserted into the mounting channel 110 of the atomizing core support 100 from one end port of the atomizing core support 100, so that the main body part 210 and the extension part 230 of the liquid guide 200 are completely arranged in the mounting channel 110 of the atomizing core support 100, and the clamping part 220 is at least partially positioned in the slit 120 of the atomizing core support 100 and is limited by the limiting end face 130 of the slit 120, and in the obtained atomizing core, the outer peripheral side wall of the main body part 210 can be in close contact with the inner wall of the mounting channel 110 under the elastic action of a soft fiber material, and the outer wall of the extension part 230 can be in close contact with the inner wall of the mounting channel 110 under the effect of the soft fiber material, even though the elastic force of the soft fiber material can not be in contact with the inner wall of the mounting channel 110, and the sealing end face of the sealing core can not be completely formed, and the sealing joint structure can be difficult to realize, even if the joint structure can be formed to the inner sealing joint between the inner end of the sealing end surface and the slit and the sealing end surface of the slit can be completely contacted with the inner end face and the sealing end face of the slit 100.

Since the outer wall of the extension 230 is in close contact with at least the junction between the inner wall of the mounting channel 110 and the limiting end surface 130, in this embodiment, the outer wall of the extension 230 may be in close contact with only the inner wall of the junction between the inner wall of the mounting channel 110 and the limiting end surface 130, or may be in close contact with the inner wall of the mounting channel 110 near the bottom of the slit 120 (the inner wall includes the inner wall of the junction between the mounting channel 110 and the limiting end surface 130, and the inner wall forms a closed loop). Preferably, the outer wall of the extension 230 is in close contact with the inner wall of the mounting channel 110 near the bottom of the slit 120, so that the inner wall of the mounting channel 110 near the bottom of the slit 120 can be sealed by the extension 230, thereby better preventing the atomized liquid from leaking into the atomized core support 100 through the structural gap formed between the bottom of the clamping portion 220 and the bottom of the slit 120.

Further, in some alternative embodiments, the extension 230 is disposed around to form a closed loop structure, and the extension 230 is disposed coaxially with the body 210. In this embodiment, the extension portion 230 is a cylindrical structure that is disposed around, and the inner space of the extension portion 230 is communicated with the inner space of the main body portion 210, so that the inner space of the extension portion 230 and the inner space of the main body portion 210 are communicated with the space of the mounting channel 110 except for the extension portion 230 and the main body portion 210. The heating element 300 may be disposed around the inner space of the main body 210, and the inner space of the extension 230, and is not limited thereto.

In this embodiment, in implementation, in some alternative embodiments, as shown in fig. 5-6, the height d1 of the main body 210 may be equal to the height d3 of the clamping portion 220 along the axial direction of the liquid guiding body 200, and in other alternative embodiments, the height d1 of the main body 210 may be greater than the height d3 of the clamping portion 220. As shown in fig. 6, when the height d1 of the main body 210 is equal to the height d3 of the fastening portion 220, the whole liquid guiding body 200 may be formed by enclosing a piece of sheet-shaped soft fiber material in an inverted "convex" shape; when the height d1 of the main body 210 is greater than the height d3 of the fastening portion 220, the entire liquid guiding body 200 may be formed by enclosing a sheet of inverted cross-shaped soft fiber material.

In this embodiment, in the implementation, the number of slits 120 formed on the side wall of the atomizing core support 100 may be flexibly set according to actual needs, and may be one or more, which is not limited in this embodiment.

Alternatively, in some structural designs, as shown in fig. 3 and 4, the number of slits 120 may be one, and the number of the clamping portions 220 is equal to the number of slits 120, where the liquid guiding body 200 may be formed by enclosing a piece of sheet-shaped soft fiber material body in an inverted "convex" shape. Specifically, as shown in fig. 6, the protruding portion A1 of the sheet-shaped soft fiber material body is surrounded to form a cylindrical extension portion 230, the middle portion A2 corresponding to the protruding portion A1 is surrounded to form a cylindrical main body portion 210, and opposite surfaces of the two side portions A3 located at the middle portion A2 are abutted together to form a protruding clamping portion 220, so that the liquid guide body 200 having the main body portion 210, the clamping portion 220 and the extension portion 230 is formed. In this embodiment, it can be understood that, in some specific application scenarios, the heat generating body 300 is wrapped by doubling up the sheet-shaped soft fiber material body in the shape of an inverted "convex" along the circumferential direction of the cylindrical heat generating body 300, so that the liquid guiding body 200 having the main body 210, the clamping portion 220 and the extension portion 230 can be formed, and the cylindrical heat generating body 300 can be in close contact with the annular inner wall of the main body 210.

Alternatively, in other structural designs, as shown in fig. 1-2 and fig. 8, the number of the slits 120 may be two, the number of the clamping portions 220 is equal to the number of the slits 120, each clamping portion 220 is disposed in one-to-one correspondence with each slit 120, and at this time, the liquid guide 200 may be formed by enclosing two inverted "convex" sheet-shaped soft fiber material bodies together. Specifically, as shown in fig. 7, two inverted-convex sheet-shaped soft fiber material bodies are enclosed by folding, wherein the end surfaces of two opposite sides of the protruding portion B1 of the two soft fiber material bodies are respectively closely abutted together to form an extension portion 230, the middle portion B2 of the two soft fiber material bodies corresponding to the protruding portion B1 is enclosed to form a main body portion 210, and the opposite surfaces of two opposite side portions B3 of the two soft fiber material bodies located at the middle portion B2 are respectively abutted together to form two clamping portions 220, so that a liquid guide 200 having the main body portion 210, the extension portion 230 and the two clamping portions 220 can be formed. In this embodiment, it can be understood that, in some specific application scenarios, by placing two sheets of soft fiber material bodies in the shape of inverted "convex" on opposite sides of the tubular heating element 300, the two sheets of soft fiber material bodies are disposed at opposite intervals, and the tubular heating element 300 is located between two middle portions B2 of the two sheets of soft fiber material bodies, and then wrapping the heating element 300 in a manner of folding the two sheets of soft fiber material bodies in half along the circumferential direction of the tubular heating element 300, the liquid guide 200 having the main body 210, the extension portion 230, and the two clamping portions 220 can be formed, and the tubular heating element 300 can be in close contact with the annular inner wall of the main body 210.

In this embodiment, it is understood that the inverted "convex" shaped sheet-like soft fiber material body is not limited to the regular inverted "convex" shape structure, but may be an irregular inverted "convex" shape structure, for example, the above-mentioned convex portion A1 or convex portion B1 is not limited to the square structure, and may be a combination of the square structure and other structures, for example, a combination of the square structure and the circular arc structure, so long as the liquid guiding body 200 having the main body portion 210, the clamping portion 220 and the extending portion 230 can be enclosed. Based on the above-mentioned structural design of the atomizing core, when the liquid guide 200 is mounted on the atomizing support 100, the clamping portion 220 formed by the two side portions A3 and B3 has three structures, namely, the outer peripheral wall of the atomizing core support 100 is protruded from one side of the clamping portion 220 away from the main body 210 (as shown in fig. 8), one side surface of the clamping portion 220 away from the main body 210 is flush with the outer peripheral wall of the atomizing core support 100 (as shown in fig. 1 and 3), and one side of the clamping portion 220 away from the main body 210 is located between the inner and outer peripheral walls of the atomizing core support 100 (i.e. located in the slit 120). In this embodiment, preferably, a side surface of the clamping portion 220 facing away from the main body portion 210 is flush with the outer peripheral wall of the atomizing core holder 100, so that the appearance of the entire atomizing core can be more attractive.

In the present embodiment, it is understood that the atomizing core shown in fig. 1 can be obtained on the basis of the atomizing core shown in fig. 8, specifically, in the actual production process, no part of the clamping portion 220 protruding from the outer circumferential wall of the atomizing core holder 100 can be cut out by cutting, so that the clamping portion 220 is flush with the outer circumferential wall of the atomizing core holder 100.

In addition, when the atomizing core is of a structure in which the engaging portion 220 protrudes from the outer peripheral wall of the atomizing core holder 100 as shown in fig. 8, a portion of the engaging portion 220 protruding from the outer peripheral wall of the atomizing core holder 100 may be left. At this time, the atomizing core can be assembled by adding the liquid storage mode, specifically, the atomizing core further comprises a cylindrical liquid storage body (not shown), the liquid storage body is sleeved outside the atomizing core support 100, the clamping portion 220 protrudes out of the outer peripheral wall of the atomizing core support 100, the part of the outer peripheral wall of the liquid storage body can be inserted into the inner wall of the liquid storage body, at this time, atomized liquid absorbed by the liquid storage body can be conducted into the main body 210 through the clamping portion 220, and needed atomized liquid is provided for atomizing the heating element 300. In some embodiments, as shown in fig. 1 and 3, at least one liquid inlet 140 is formed on a side wall of the atomizing core support 100, the liquid inlet 140 and the slit 120 are spaced along the circumferential direction of the atomizing core support 100, and the inner wall of the liquid storage and the outer peripheral side wall of the main body 210 each block each liquid inlet 140, so that the atomized liquid can sequentially pass through the liquid storage and the liquid inlet 140 and enter the main body 210 of the liquid guide 200, and the atomized liquid adsorbed on the inner wall of the main body 210 can be atomized into aerosol for the user to suck after the heating element 300 is electrified and heated. It will be appreciated herein that in some embodiments where no reservoir is provided, the aerosolized liquid may be directed into the body portion 210 of the liquid guide 200 through the liquid inlet aperture 140 in the aerosolized wick support 100.

Alternatively, in the embodiment, the liquid storage may be made of the same material as the liquid guiding body 200, or may be made of a different material from the liquid guiding body 200, so long as the use requirement of absorbing and conducting the atomized liquid can be satisfied, which is not particularly limited in this embodiment. In some application scenarios using an atomization core, the main effect of the liquid storage is that the risk of dry combustion caused by lack of liquid in the atomization core can be reduced, and in particular, in the process of applying electricity to heat the heating element 300, the atomized liquid absorbed by the main body 210 of the liquid guide 200 is gradually consumed, and because a certain amount of atomized liquid is stored in the liquid storage, when the atomized liquid contained in the main body 210 is reduced, the atomized liquid can be timely supplemented to the main body 210 through the liquid storage, so that the heating element 300 can timely obtain enough atomized liquid to heat and atomize, and thus the risk of lack of liquid and dry combustion caused by the heating element 300 can be effectively reduced.

Further, to better prevent leakage of the atomized liquid into the atomized core support 100, in some alternative embodiments, as shown in fig. 5, the height d2 of the extension portion 230 is 1/7-1/3 of the height d1 of the main body portion 210 along the axial direction of the liquid guide 200. By means of the arrangement, the contact area between the extension part 230 and the joint of the inner wall of the mounting channel 110 and the limiting end face 130 can be increased, so that the sealing effect between the extension part 230 and the joint of the mounting channel 110 and the limiting end face 130 is better, and the problem of liquid leakage of the atomization core can be better prevented.

Further, in some alternative embodiments, the length of the slit 120 is 1/3 to 3/4 of the length of the atomizing core support 100 along the axial direction of the atomizing core support 100, so that the atomizing core support 100 can accommodate the liquid guide 200 and the heating element 300 with larger volume on the premise that the diameter of the atomizing core support 100 is kept unchanged, and the aerosol generated in unit time of the atomizing core can be improved.

Further, in some alternative embodiments, the height of the clamping portion 220 is less than or equal to the length of the slot 120 along the axial direction of the atomizing core support 100, such that the clamping portion 220 can be completely disposed within the slot 120. By this arrangement, the upper end portion of the engaging portion 220 can be prevented from affecting the appearance of the atomizing core by protruding the upper end portion of the atomizing core holder 100.

Further, in some alternative embodiments, the width of the clamping portion 220 is less than or equal to the width of the slit 120 along the radial direction of the atomizing core support 100, so that the clamping portion 220 is clamped in the slit 120.

Further, in some alternative embodiments, the clamping portion 220 is disposed at a right angle to the extending portion 230, and an end surface of the clamping portion 220 near the limiting end surface 130 contacts the limiting end surface 130, so that the whole liquid guiding body 200 can be more stably clamped in the atomizing core support 100, and the risk that the atomized liquid leaks into the atomizing core support 100 from a gap between the bottom of the clamping portion 220 and the limiting end surface 130 is further reduced.

Correspondingly, referring to fig. 9, an embodiment of the present utility model further provides an atomizer, which includes a housing 1 and an atomization core in any of the above embodiments, wherein the atomization core is installed in the housing 1, an air flow channel 11 communicating with the outside and a liquid storage cavity 12 for storing atomized liquid are provided in the housing 1, the atomization core is installed in the air flow channel 11, and the liquid guide 200 is communicated with the liquid storage cavity 12.

In this embodiment, the atomizer of this embodiment also has the same technical effects as the above-mentioned atomizing core thanks to the improvement of the above-mentioned atomizing core, and will not be described again here.

Correspondingly, referring to fig. 10, the embodiment of the present utility model further provides an electronic atomization device, which includes a power supply assembly 2 and the atomizer in any of the above embodiments, wherein the power supply assembly 2 is electrically connected to the heating element 300, and the power supply assembly 2 is used for providing electric energy for the heating element 300, so that the heating element 300 can be electrified to generate heat and vaporize the atomized liquid located on the inner wall of the main body 210 of the liquid guide 200 into aerosol for the user to inhale.
