Description

Technical Field

[0001] The present invention relates to the technical field of atomization, and particularly to an atomizing core guiding liquid and its heating atomizing core.

Background Art

[0002] The liquid guiding cloth can be used as a liquid guiding member of an electronic atomization device, and functional elements such as the liquid transmission efficiency and heat resistance thereof affect the quality of the atomization core. At present, most of the methods in the industry pursue differences in materials such as linen fiber, long fiber cloth fiber, and mixed fiber, or pursue differences in technology (degreasing before spinning or degreasing after spinning), or adjust the density of the cloth per unit volume (that is, the weight of the cloth per unit volume). These methods are generally used in the industry and aim to achieve the liquid supply efficiency by adjusting the liquid guiding cloth. However, the liquid guiding of the guiding liquid is still uneven and the liquid guiding speed is slow.

Embodiments for Carrying out the Invention

[0023] For a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will be described in detail with reference to the drawings.

[0024] When a member is described as "fixed to" or "provided on" another member, it can be directly or indirectly located on the other member. Also, when a member is described as "connected to" another member, it can be directly or indirectly connected to the other member.

[0025] Directions or positions indicated by terms such as "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "ceiling", "bottom", "inner", "outer", etc. are based on the directions or positions shown in the drawings and are for convenience of description only, and should not be construed as limiting the present technical solution. Also, terms such as "first", "second", etc. are for convenience of description only and should not be construed as indicating relative importance or suggesting the number of technical features. Also, "a plurality" means two or more unless specifically and clearly limited otherwise.

[0026] In Example 1, as shown in FIGS. 1 to 4, the atomization core liquid guide 2 is formed by overlapping a plurality of layers of liquid guide cloths 21. The liquid guide cloth 21 is manufactured from different materials such as, for example, linen fiber, long fiber cotton fiber, spunlace non-woven fabric fiber, mixed fiber, etc. Also, at least one surface of at least one layer of the liquid guide cloth 21 has stripes. As a result, the space between at least two adjacent layers of the liquid guide cloth 21 is not completely in close contact, and minute grooves 22 are formed. Also, a plurality of minute grooves 22 communicate with each other to form a liquid storage space. Note that "overlapping" refers to spatial stacking. That is, the atomization core liquid guide 2 is formed by stacking the liquid guide cloths 21 layer by layer in space. Also, "close contact" means that there is contact between two objects and there is no gap at the contact position. The stripes in the present invention are not patterns in the conventional sense, but are depressions or protrusions formed on the surface of the liquid guide cloth 21 by knitting in the textile process of the liquid guide cloth 21. Alternatively, they are depressions or protrusions that appear on the surface of the liquid guide cloth 21 by technical means such as die pressing, adjustment of textile parameter settings, extrusion, etc. At least one surface of at least one layer of the liquid guide cloth 21 is concave or convex. In the plurality of layers of liquid guide cloths 21 that are overlapped, due to the presence of the stripes, the space between at least two adjacent layers of the liquid guide cloth 21 is not completely in close contact, and minute grooves 22 are formed. Also, a plurality of minute grooves 22 communicate with each other to form a liquid storage space, and liquid is stored in the liquid storage space. In the actual use process, it is possible to store a large amount of liquid in the minute grooves 22 。Complex By providing several layers of the liquid guide cloth 21, compared with the liquid guide cloth 21 of the conventional structure without minute grooves 22, when the liquid on the innermost liquid guide cloth 21 close to the heating element 3 is consumed during the atomization process, the liquid at other positions of the liquid guide cloth 21 transfers the liquid to the innermost liquid guide cloth 21 by capillary action. Also, since the position of the liquid storage space inside the liquid guide cloth 21 is close to the liquid tank More heating element 3 outside the liquid guide cloth 21, the liquid stored in the liquid storage space can exhibit a rapid liquid supply effect. As a result, the liquid guiding efficiency is improved, and the atomization effect is optimized.

[0027] Multiple layers of The liquid guide cloth 21 is At least two layers of vertical stripe liquid guide cloth 211, or at least two layers of horizontal stripe liquid guide cloth 212, or At least one layer of longitudinally striped liquid guiding cloth 211 and It includes at least one layer of horizontally striped liquid guiding cloth 212. As shown in Fig. 5, the longitudinally striped liquid guiding cloth 211 is provided with stripes arranged longitudinally as a whole, forming micro-grooves 22 that are longitudinally oriented as a whole. Being arranged longitudinally as a whole means that the stripes of the liquid guiding cloth 21 extend from the upper end to the lower end as a whole. That is, the micro-grooves 22 extend from the upper end to the lower end as a whole. However, it is not required that each stripe be provided from top to bottom. Based on the longitudinally oriented stripes, branched stripes may extend outward, or longitudinally oriented stripes and horizontally oriented stripes may be provided in an intersecting manner. As shown in Fig. 6, the horizontally striped liquid guiding cloth 212 is provided with stripes arranged horizontally as a whole, forming micro-grooves 22 that are horizontally oriented as a whole. Being arranged horizontally as a whole means that the stripes of the liquid guiding cloth 21 extend from the left side to the right side as a whole. That is, the micro-grooves 22 extend from the left side to the right side as a whole. However, it is not required that each stripe penetrate from left to right. Based on the horizontally oriented stripes, branched stripes may extend outward, or longitudinally oriented stripes and horizontally oriented stripes may be provided in an intersecting manner. Multiple overlapping methods can be adopted for the atomization core liquid guide formed by these two types of striped liquid guiding cloth 21. It may be composed of multiple layers of horizontally striped liquid guiding cloth 212, or multiple layers of longitudinally striped liquid guiding cloth 211, or may be formed by combining and overlapping multiple layers of horizontally striped liquid guiding cloth 212 and longitudinally striped liquid guiding cloth 211.

[0028] Due to the difference in the types of stripes of the liquid guiding cloth 21, different micro-grooves 22 can be formed by different arrangements. That is, when the longitudinally striped liquid guiding cloth 211 and the horizontally striped liquid guiding cloth 212 are overlapped in an intersecting manner, that is, when one layer of longitudinally striped liquid guiding cloth 211 is overlapped on one layer of horizontally striped liquid guiding cloth 212 and repeatedly adhered closely, In each adjacent two layers One layer of longitudinally oriented micro-grooves 22 And One layer of horizontally oriented micro-grooves 22 Having The liquid guide 2 is formed. Also, the minute grooves 22 of each layer communicate to form a liquid storage space. In this case, the liquid guide 2 has a liquid storage space of multiple layers. Alternatively, half of the liquid guide cloth 21 of the liquid guide 2 is made into a vertical stripe liquid guide cloth 211, and the other half is made into a horizontal stripe liquid guide cloth 212. That is, several vertical stripe liquid guide cloths 211 with the same stripes are overlapped, several horizontal stripe liquid guide cloths 212 with the same stripes are overlapped, and then both are overlapped, so that minute grooves 22 are formed on these contact surfaces. In this case, the liquid guide 2 has only one layer of minute grooves 22. That is, a liquid storage space is formed in the center of the liquid guide 2. Alternatively, all are made into vertical stripe liquid guide cloths 211 and the stripes are made different or partially different. In this case, when the vertical stripe liquid guide cloths 211 are overlapped, the raised or recessed portions are arranged offset. Thereby, the raised or recessed portions of the vertical stripe liquid guide cloths 211 of each layer do not completely overlap when projected in the radial direction, and vertical minute grooves 22 are formed. Also, the difference in the degree of offset can affect the size of the formed minute grooves 22, and thus also affects the size of the liquid storage space. Alternatively, all are made into horizontal stripe liquid guide cloths 212 and the stripes are made different or partially different. In this case, when the horizontal stripe liquid guide cloths 212 are overlapped, the raised or recessed portions are arranged offset. Thereby, the raised or recessed portions of the horizontal stripe liquid guide cloths 212 of each layer do not completely overlap when projected in the radial direction, and horizontal minute grooves 22 are formed. Also, the difference in the degree of offset can affect the size of the formed minute grooves 22, and thus also affects the size of the liquid storage space. Note that the size of the stripes is not limited. Also, the formation of the minute grooves 22 is not limited to the above form. Different minute grooves 22 are formed by the raised or recessed portions of the stripes being offset to a certain extent, but it is not specifically described.

[0029] The liquid guiding cloth 21 may be a liquid guiding cloth 21 having stripes on one side or a liquid guiding cloth 21 having stripes on both sides. Due to the structural differences of the liquid guiding cloth 21, different minute grooves 22 can be formed by overlapping. That is, when the non-striped surface of the liquid guiding cloth 21 is brought into close contact with the striped surface of another liquid guiding cloth 21, that is, when a single-layer liquid guiding cloth 21 having stripes on one side and a single-layer liquid guiding cloth 21 having no stripes are repeatedly overlapped, minute grooves 22 are formed on the contact surface of the two types of liquid guiding cloth 21. Also, the minute grooves 22 communicate to form a liquid storage space. In this case, the liquid guide 2 has a plurality of layers of liquid storage spaces. Alternatively, a single-layer liquid guiding cloth 21 having stripes on one side and a single-layer liquid guiding cloth 21 having stripes on both sides are repeatedly overlapped. In this case, the striped surface of the liquid guiding cloth 21 having one layer of stripes is in contact with any surface of the liquid guiding cloth 21 having two layers of stripes, so that the stripes are provided so as to intersect (that is, the depressions or protrusions on the surfaces of the two liquid guiding cloths 21 do not overlap and come into close contact). And, the non-striped surface of the liquid guiding cloth 21 having one layer of stripes is in contact with any surface of another liquid guiding cloth 21 having two layers of stripes. Also in this case, a plurality of layers of minute grooves 22 can be formed, and the minute grooves 22 communicate to form a liquid storage space. Also in this case, the liquid guide 2 has a plurality of layers of liquid storage spaces. Alternatively, half of the liquid guiding cloth 21 of the liquid guide 2 is a single-sided stripe, and half is a double-sided stripe liquid guiding cloth 212. That is, by overlapping several layers of single-sided stripe liquid guiding cloth 21, overlapping several layers of double-sided stripe liquid guiding cloth 21, and then overlapping the two, minute grooves 22 are formed on the contact surface. In this case, the liquid guide 2 has only one layer of minute grooves 22. That is, a liquid storage space is formed in the center of the liquid guide 2. Note that the size of the stripes is not limited. Also, the formation of the minute grooves 22 is not limited to the above form. Different minute grooves 22 are formed when the raised or depressed portions of the stripes are displaced to a certain extent, but will not be specifically described. Also, the liquid guiding cloth 21 is 2Although there are 8 layers provided, the specific number of the liquid guiding cloth 21 is not limited. Moreover, the arrangement positions of the minute grooves 22 between different layers are provided such that at least a part thereof intersects in the radial direction. In the present application, the expression "provided so as to intersect" means that there is a deviation in the arrangement in the radial direction of the minute grooves 22 formed when the liquid guiding cloths 21 of different layers are superposed, and they do not necessarily correspond one-to-one. The difference in the degree of this deviation may affect the size of the minute grooves 22 formed, that is, the size of the liquid storage space.

[0030] The stripe directions of the liquid guiding cloth 21 are the same and are regularly arranged. That is, the stripes are repeating units and are arranged with a certain rule. Alternatively, the stripe directions of the liquid guiding cloth 21 are the same as a whole. Thereby, when forming the stripes of the liquid guiding cloth 21, a desired stripe can be realized by using a relatively simple technical means, and it becomes even simpler when superposing the liquid guiding cloths 21, resulting in cost savings in production.

[0031] The height of the minute grooves 22 of the liquid guide 2 is within 0.1 mm. By controlling the height of the minute grooves 22, the size of the liquid storage space is controlled. The liquid guiding cloth 21 becomes saturated when adsorbing liquid to a certain extent. However, if the liquid storage space is too large, the liquid guide 2 may become supersaturated and liquid may overflow from the liquid guide 2, ultimately affecting the atomization effect.

[0032] As shown in FIGS. 1 to 2, the liquid guide 2 may have a cylindrical structure, or as shown in FIGS. 3 to 4, it may have a plate-like structure. Depending on the actual structure of the atomization core, the liquid guide 2 may be cylindrical or may have a plate-like structure, and the actual shape can be changed according to actual needs.

[0033] The minute grooves are formed in various ways. Therefore, the forms of the liquid storage space are also various, and they may be uniformly arranged on the contact surfaces of the liquid guiding cloths of each layer, or the liquid storage spaces may be arranged every other layer, and they may be vertical or horizontal, but are not specifically described here.

[0034] In Example 1-1, as shown in FIG. 1, the liquid guide 2 has a cylindrical structure. The liquid guide 2 is formed by overlapping a horizontally striped liquid guide cloth 212 and a vertically striped liquid guide cloth 211, and the two types of liquid guide cloths are each half. Also, the inside of the liquid guide 2 is the vertically striped liquid guide cloth 211, and the outside is the horizontally striped liquid guide cloth 212. Minute grooves 22 are formed on the contact surface between the horizontally striped liquid guide cloth 212 and the vertically striped liquid guide cloth 211, and a plurality of minute grooves 22 communicate with each other to form a liquid storage space. In this case, the liquid guide 2 has one layer of liquid storage space.

[0035] In Example 1-2, as shown in FIG. 2, the liquid guide 2 has a cylindrical structure. The liquid guide 2 is formed by overlapping a plurality of layers of vertically striped liquid guide cloths 211, and the vertical stripes of the vertically striped liquid guide cloths 211 of each layer are provided so as to intersect. That is, since the depressions or protrusions on the surfaces of two adjacent liquid guide cloths 21 do not overlap and adhere closely, minute grooves 22 are formed. Also, the minute grooves 22 of each layer communicate with each other to form a liquid storage space. In this case, the liquid guide 2 has a plurality of layers of liquid storage spaces.

[0036] In Example 1-3, as shown in FIG. 3, the liquid guide 2 has a plate-like structure. The liquid guide 2 is formed by overlapping a horizontally striped liquid guide cloth 212 and a vertically striped liquid guide cloth 211, and the two types of liquid guide cloths are each half. Of different layers The stripes of the vertically striped liquid guide cloth 211 are the same, Of different layers and the stripes of the horizontally striped liquid guide cloth 212 are the same. Minute grooves 22 are formed on the contact surface between the innermost horizontally striped liquid guide cloth 212 and the innermost vertically striped liquid guide cloth 211, and a plurality of minute grooves 22 communicate with each other to form a liquid storage space. In this case, the liquid guide 2 has one layer of liquid storage space.

[0037] In Example 1-4, as shown in FIG. 4, the liquid guide 2 has a plate-like structure. The liquid guide 2 is formed by overlapping a plurality of layers of horizontally striped liquid guide cloths 212, and the horizontal stripes of the horizontally striped liquid guide cloths 212 of each layer are provided so as to intersect. That is, since the depressions or protrusions on the surfaces of two adjacent liquid guide cloths 21 do not overlap and adhere closely, minute grooves 22 are formed. Also, the minute grooves 22 of each layer communicate with each other to form a liquid storage space. In this case, the liquid guide 2 has a plurality of layers of liquid storage spaces.

[0038] In Example 2, as shown in FIGS. 7 to 11, the heating atomization core includes the liquid guide 2 of Example 1 and a heating element 3 in close contact with the liquid guide 2. The heating element 3 is connected to the electrode lead wire 4. During operation, the electrode lead wire 4 supplies electricity to the heating element 3 to generate heat, atomizing the tobacco liquid in the liquid guide 2 to form atomized vapor. This is finally inhaled by the user.

[0039] As shown in FIGS. 7 to 9, the heating element 3 includes a central heating circuit, and the electrode lead wires 4 are connected to both ends. Generally, it is made of an alloy with a high electrical resistivity such as stainless steel, nickel chromium, iron chromium aluminum, nickel iron, etc. The heating element 3 can be divided into a cylindrical heating element 3 formed by winding a planar mesh-shaped heating element 3, a heating element 3 composed of a spiral wire, and a heating element 3 formed by cutting a metal tube and making it translucent. Also, the direction of the heating circuit is a heating element 3 that extends horizontally as a whole, or a heating element 3 that extends vertically as a whole, or a heating element 3 with a mesh structure These three types and is roughly classified into these.

[0040] In Example 2-1, as shown in FIGS. 10 to 11, the heating atomization core further includes an atomization core casing 1. The liquid guide 2 is provided in the atomization core casing 1, and in the atomization core casing 1 below the liquid guide 2 Electrode lead wire 4A fixing member 5 for fixing is provided. An air flow supply hole 51 is formed in the fixing member 5. The heating element 3 is in close contact with the liquid guide 2, and the liquid guide 2 is provided in the atomization core casing. By being constrained by the atomization core casing 1, both the liquid guide 2 and the heating element 3 are fixed in the atomization core casing 1. Moreover, by fixing the electrode lead wire 4 with the fixing member 5, the problem that when the electrode lead wire 4 receives force and wobbles, the heating circuit of the heating element 3 also wobbles together is avoided, and the problem of poor contact between the liquid guide 2 and the heating element 3 is solved. Further, a liquid guide hole 11 is provided in the side wall of the atomization core casing 1, and the contact area between the liquid and the liquid guide 2 is controlled by the size of the liquid guide hole 11. During operation, the liquid enters the liquid guide 2 from the liquid guide hole 11 on the side wall of the atomization core casing 1 and flows to the liquid guide 2. Also, the electrode lead wire 4 supplies electricity to the heating element 3 to generate heat, so that the tobacco liquid in the liquid guide 2 is atomized to form atomized vapor. At this time, the gas entering from the air flow supply hole 51 introduces the atomized vapor into the air flow path and is finally inhaled by the user.

[0041] As shown in FIG. 11, a positioning groove 52 is formed in the outer peripheral edge of the fixing member 5, and the electrode lead wire 4 is engaged and fixed in the positioning groove 52. The cross-sectional shape of the positioning groove 52 may be in the shape of an arc, a U shape, a V shape, a quadrangle, etc., but it is preferably a V shape with a large opening and easy insertion, and capable of completely clamping and fixing the electrode lead wire 4. The number of installation of the positioning groove 52 is at least one. When one is provided, the two electrode lead wires 4 are fixed together. Also, when two positioning grooves 52 are provided, the two electrode lead wires 4 are engaged in different positioning grooves 52. Also, when a plurality of positioning grooves 52 are provided, the plurality of positioning grooves 52 are uniformly provided on the outer peripheral edge of the fixing member 5, and the two electrode lead wires 4 are engaged in any two positioning grooves 52. Also, in another embodiment, a fixing hole penetrating the fixing member 5 is provided, and the electrode lead wire 4 is inserted into the fixing hole.

[0042] In Example 2-2, the heating circuit of the heating element 3 is fitted corresponding to being within the concave grooves of the liquid guide 2 or between the adjacent raised grooves. The term "fitted" in the text may mean that the heating circuit of the heating element 3 can be entirely arranged within the concave grooves of the liquid guide 2 or between the adjacent raised grooves, or it may mean that it can be partially arranged within the concave grooves of the liquid guide 2 or between the adjacent raised grooves. When it is entirely arranged, the heating circuit Extension direction of is the same as the grooves of the liquid guide cloth 21. Note that it is not the case that the larger the area of the heating element 3 fitted in the liquid guide 2, the better. When the area of the heating element 3 fitted in the liquid guide 2 is too large, all of the heating element 3 will be immersed in the liquid of the liquid guide 2, and during the atomization operation, all of the atomized vapor will be surrounded by the liquid, and problems such as spitback are likely to occur. Therefore, Liquid guide 2 the area of the heating element 3 fitted in

[0043] is preferably 1 / 3 to 2 / 3 of the total area of the heating circuit of the heating element 3. In this case, problems such as spitback and charring are less likely to occur. Furthermore, since the heat of the heating element 3 can be maximally utilized for the atomization operation, the atomization effect is improved, resulting in an improved inhalation experience for the user. Liquid guide 2The area of the heating circuit of the heating element 3 embedded therein increases. When the wire diameter of the heating element 3 is thick, for example, when it is 0.2 mm or more, it is preferable that the extending direction of the heating circuit of the heating element 3 and the direction of the stripes of the liquid guide 2 are generally the same. For example, when the heating circuit of the heating element 3 extends horizontally and the direction of the stripes of the liquid guide 2 is also horizontal, that is, when the minute groove 22 is a horizontal minute groove 22, the contact area between the heating element 3 and the liquid guide 2 increases and the atomization area increases. On the other hand, when the wire diameter of the heating element 3 is thin, for example, when the wire diameter is 0.15 mm or less, it is preferable that the extending direction of the heating circuit of the heating element 3 and the direction of the stripes of the liquid guide 2 do not generally match. For example, when the heating circuit of the heating element 3 extends horizontally and the direction of the stripes of the liquid guide 2 is vertical, that is, when the minute groove 22 is a vertical minute groove 22, the atomization effect of the atomization core becomes even better.
