Advantages of the Invention

The stripes of the longitudinally striped liquid guiding cloth form tiny grooves or / and tiny protrusions that are arranged longitudinally as a whole, and the stripes of the horizontally striped liquid guiding cloth form tiny grooves or / and tiny protrusions that are arranged horizontally as a whole. By providing the tiny grooves or / and tiny protrusions formed in the longitudinal stripes in a manner adaptable to the circuit structure of the heating member, the heating member is slightly inserted into the liquid guiding cloth to increase the atomization area. Also, the reason for adopting the horizontal stripes is that the horizontal stripes have horizontal tiny grooves or / and tiny protrusions. By doing so, capillary gaps are formed inside the liquid guiding cloth. Since the liquid transfer speed along the direction of the tiny grooves or / and tiny protrusions is higher than that in other directions, the liquid at the liquid supply hole can be better guided in all directions. As a result, the liquid guiding of the liquid guiding member becomes uniform, the liquid guiding efficiency and atomization effect are improved, and thus the inhalation experience of the user is improved.

Embodiments for Carrying Out the Invention

[0029] To more clearly understand 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.

[0030] When a member is described as being "fixed to" or "provided on" another member, it may be directly or indirectly located on the other member. Also, when a member is described as being "connected to" another member, it may be directly or indirectly connected to the other member.

[0031] 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 only for the convenience of description and should not be construed as limiting the present technical solution. Also, terms such as "first", "second", etc. are only for the convenience of description and should not be construed as indicating relative importance or suggesting the number of technical features. Also, "a plurality" means two or more, unless otherwise clearly and specifically limited.

[0032] In Example 1, as shown in FIGS. 1 to 7, the heating atomization core includes an atomization core casing 30. A cylindrical liquid guide 33 is provided inside the atomization core casing 30, and a heating member 31 is in close contact with the inner wall of the liquid guide 33. Also, an electrode 32 is connected to the heating member 31. A liquid guide hole 301 for guiding liquid toward the liquid guide 33 is provided in the side wall of the atomization core casing 30. One or more liquid guide holes 301 may be provided, but the specific number is not limited. The liquid guide 33 has a cylindrical structure formed by stacking and winding a plurality of layers of liquid guide cloth. The liquid guide cloth At least two layers of vertical stripe liquid guiding cloth 332, or at least two layers of horizontal stripe liquid guiding cloth 331, or at least one layer of longitudinally striped liquid guide cloth 332 and includes at least one layer of horizontally striped liquid guide cloth 331. The horizontally striped liquid guide cloth 331 and / or The overlapping position of the vertical-striped liquid guiding cloth 332 is not limited, and it may be provided inside and adhered to the heat generating member 31, or it may be provided in the middle. Naturally, it may also be provided outside and brought into contact with the liquid guiding hole 301. The liquid guiding cloth may have each layer as the horizontal-striped liquid guiding cloth 331, or each layer may be the vertical-striped liquid guiding cloth 332. Naturally, it may also have both the horizontal-striped liquid guiding cloth 331 and the vertical-striped liquid guiding cloth 332. Preferably, the vertical-striped liquid guiding cloth 332 is provided on the innermost side and adhered to the heat generating member 31, and the horizontal-striped liquid guiding cloth 331 is provided on the outermost side and contacts the liquid guiding hole 301. The vertical-striped liquid guiding cloth 332 is provided with minute grooves or / and minute protrusions formed by stripes arranged vertically as a whole, and the horizontal-striped liquid guiding cloth 331 is provided with minute grooves or / and minute protrusions formed by stripes arranged horizontally as a whole. Also, inside the atomizing core casing 30 below the liquid guiding body 33, a fixing member 34 for fixing the electrode 32 is provided. An air flow supply hole 341 is formed in the fixing member 34. During operation, the liquid enters the liquid guiding body 33 from the liquid guiding hole 301 on the side wall of the atomizing core casing 30 and flows to the horizontal-striped liquid guiding cloth 331 outside the liquid guiding body 33. The liquid flows circumferentially along the minute horizontal protrusions and minute grooves and penetrates into the inner layer of the vertical-striped liquid guiding cloth 332. The heat generating member 31 is fitted into the minute grooves or between the minute protrusions on the vertical-striped liquid guiding cloth 332. Therefore, when the electrode 32 supplies electricity to the heat generating member 31 to generate heat, the tobacco liquid in the liquid guiding body 33 is atomized to form atomized vapor. At this time, the gas entering from the air flow supply hole 341 guides the atomized vapor into the air flow path and is finally inhaled by the user.

[0033] As shown in FIGS. 15 to 18, the vertical-striped liquid guiding cloth 332 stripes of is arranged vertically as a whole. Being arranged vertically as a whole means that vertical stripe liquid guiding cloth 332It means that the entire stripe extends from the upper end to the lower end. However, it is not required that each stripe penetrates from top to bottom. Based on the vertical stripes, the branched stripes may extend outward, or the vertical stripes and the horizontal stripes may be arranged in an intersecting manner. Since the vertical liquid guiding cloth 332 is provided with stripes that are generally arranged vertically, the formed minute grooves and minute protrusions can be changed to a vertical mounting path. Since the vertical heat generating circuit of the heat generating member 31 can be slightly fitted into this path, the contact area between the heat generating member 31 and the liquid guide 33 increases. Also, as shown in FIGS. 8 to 14, the horizontal liquid guiding cloth 331 stripes of is generally arranged horizontally. Generally arranged horizontally means that horizontal stripe liquid guiding cloth 331 the entire stripe extends from the left side to the right side. However, it is not required that each stripe penetrates from left to right. Based on the horizontal stripes, the branched stripes may extend outward, or the vertical stripes and the horizontal stripes may be arranged in an intersecting manner. Also, the stripes generally arranged horizontally in the horizontal liquid guiding cloth 331 can form minute grooves and minute protrusions, said and the minute grooves and minute protrusions form capillary gaps and change to a horizontal liquid guiding path. Since the transmission speed of the liquid along the direction of the horizontal minute protrusions and minute grooves is higher than that in other directions, the liquid can be guided better in all directions. As a result, the liquid guiding of the liquid guide 33 becomes uniform, the liquid guiding efficiency and the atomization effect are improved, and the inhalation experience of the user is improved.

[0034] The heating member 31 is a metal heating sheet, and the heating sheet may be wound into a columnar shape and adhered to the inner wall of the heat conductor. Generally, it may be manufactured from an alloy with a high electrical resistivity such as stainless steel, nickel chromium, iron chromium aluminum, nickel iron, etc., and the thickness may be between 0.03 and 0.2 mm, but the specific thickness is not limited. Also, the heating circuit and the electrodes 32 can be formed by cutting or corrosion techniques. And, for contact with the external electrodes 32, the lead wires of the electrodes 32 are welded. It is preferable to use an insulating coating on one end of the lead wires of the electrodes 32 that protrudes. As the material of the lead wires, pure nickel may be used, or silver may be plated on the surface of a copper wire. In addition, a fixing member 34 is further provided. Since the fixing member 34 can fix the lead wires of the electrodes 32, a situation where the internal heating member 31 moves due to the protruding lead wires receiving force and causing poor contact with the liquid guide 33 is prevented.

[0035] One to six layers of vertical stripe liquid guide cloth 332 are provided, but the specific number of layers is not limited. As the stacking method of the plurality of layers of vertical stripe liquid guide cloth 332, at least a part of the arrangement positions of the stripes of each layer of vertical stripe liquid guide cloth 332 correspond in the radial direction. The correspondence mentioned here means that the shapes and positions of the vertical stripes between the layers of the vertical stripe liquid guide cloth 332 correspond one-to-one, and the sizes and dimensions are the same or substantially the same. Thereby, at least a part of the heating circuit of the heating member 31 is fitted into the minute grooves of the stripes or between the adjacent minute ridges. Also, the correspondence mentioned here may mean that they correspond partially, and of course, they may correspond completely. By doing so, the contact area between the heating member 31 and the vertical stripe liquid guide cloth 332 can be increased. That is, the atomization area of the atomization surface can be increased. Thereby, the tobacco liquid in the liquid guide 33 can be atomized at a higher level, and the atomization effect is improved.

[0036] In some embodiments, there are multiple embodiments for the arrangement of the stripes on the vertical stripe liquid guiding cloth 332 and the horizontal stripe liquid guiding cloth 331. As shown in FIGS. 8 to 19, the stripes provided on the vertical stripe liquid guiding cloth 332 and the horizontal stripe liquid guiding cloth 331 are straight stripes, curved stripes, or combined stripes formed by at least one of them. That is, it may be stripes in which a single straight line is regularly aligned and uniformly arranged as shown in FIGS. 10 and 17, or it may be less regular branched arrangement stripes composed of straight lines as shown in FIG. 12, or it may be a broken line type formed by straight lines as shown in FIGS. 9 and 16. Also, the path of the stripe is not necessarily linear, and it may be a wave type formed by curves as shown in FIG. 11, or a combination type of straight line and curve as shown in FIG. 13. Also, the path of the stripe is not necessarily a continuous linear distribution, and it may be a long-strip distribution with intervals as shown in FIGS. 8 and 18, or a curved type intersecting vertically and horizontally as shown in FIG. 14, and of course, it may be a straight type intersecting vertically and horizontally. The direction of stripes such as broken lines and curved types has more liquid storage space than straight stripes, so it can ensure sufficient liquid supply during continuous operation and inhalation. Note that as long as the direction of the stripe satisfies the design principle during use, the shape and arrangement of the stripe are not specifically limited. The design principle means that the stripes used for the liquid guiding cloth in contact with the heating member 31 are vertically oriented as a whole, and the stripes used for the liquid guiding cloth in contact with the liquid guiding holes 301 on the outside are horizontally oriented as a whole.

[0037] There are multiple embodiments for the installation of the stripes on the vertical stripe liquid guiding cloth 332 and the horizontal stripe liquid guiding cloth 331. At least a part of the stripes provided on the vertical stripe liquid guiding cloth 332 penetrates from the ceiling part to the bottom part, and at least a part of the stripes provided on the horizontal stripe liquid guiding cloth 331 penetrates from one end to the other end. The reason for providing vertical stripes on the vertical stripe liquid guiding cloth 332 is to enable the formation of minute protrusions or minute grooves on the liquid guiding cloth that are in close contact with the vertical heating circuit of the heating member 31. Also, in order to increase these contact areas, at least a part of the stripes of the liquid guiding cloth penetrates from the ceiling part to the bottom part, but the remaining stripes may be horizontally oriented or obliquely oriented, and of course, all the stripes may penetrate from the ceiling part to the bottom part.

[0038] In some embodiments, the stripes provided on the vertical stripe liquid guiding cloth 332 at least partially conform to and match the shape of the heating member 31. That is, at least a part of the heating circuit of the heating member 31 is fitted into the minute grooves of the stripes or between the adjacent minute protrusions, so as to increase the atomization area of the heating member 31 and the vertical stripe liquid guiding cloth 332.

[0039] In some embodiments, one to six layers of horizontal stripe liquid guiding cloth 331 are provided. As the overlapping method of the plurality of layers of horizontal stripe liquid guiding cloth 331, at least a part of the arrangement positions of the stripes of each layer of horizontal stripe liquid guiding cloth 331 correspond in the radial direction. The so-called correspondence here means that the shapes and positions of the horizontal stripes on each layer of liquid guiding cloth correspond one-to-one, and the sizes are the same or substantially the same. Also, the so-called correspondence here may mean partial correspondence, and of course, it may also mean complete correspondence. Alternatively, the arrangement positions of the stripes of the adjacent layers of horizontal stripe liquid guiding cloth 331 are provided so that at least a part of them intersect in the radial direction. The so-called provided to intersect here means that the positions of the minute grooves or minute protrusions formed by the horizontal stripes in the adjacent horizontal stripe liquid guiding cloth 331 are shifted. That is, the protruding parts of the minute protrusions or minute grooves of the horizontal stripes in the horizontal stripe liquid guiding cloth 331 engage with the concave groove parts of the minute protrusions or minute grooves of the horizontal stripes in the liquid guiding cloth of the adjacent layer, so as to accelerate the liquid guiding speed. Also, the so-called intersection here may mean partial intersection, and of course, it may also mean complete intersection.

[0040] In some embodiments, the horizontal stripes of the horizontal-striped liquid guiding cloth 331 and the vertical stripes of the vertical-striped liquid guiding cloth 332 can be interpreted as minute protrusions or minute grooves on the surface of the liquid guiding cloth. Also, the width of the unevenness in one layer of the liquid guiding cloth is less than 0.5 mm, and the depth is less than 0.1 mm. By controlling the height and interval of the minute protrusions or minute grooves to control the amount of stored liquid, when the liquid guiding body 33 adsorbs the liquid to a certain level, it becomes saturated. Thereby, the problem that the liquid guiding body 33 may become supersaturated is avoided, and the problem that the liquid overflows from the liquid guiding body 33 and finally affects the atomization effect is solved.

[0041] In some embodiments, the stripes of the horizontal-striped liquid guiding cloth 331 are radial on both sides centered on the liquid guiding hole 301. By providing it in this way, after the liquid that has entered the liquid guiding hole 301 enters the liquid guiding cloth, it can be quickly guided in the circumferential directions on both sides. Alternatively, the density of the stripes of the horizontal-striped liquid guiding cloth 331 near the liquid guiding hole 301 is greater than the density at other positions. By providing it in this way, the liquid that has entered the liquid guiding hole 301 can be guided in all directions with the liquid guiding hole 301 as the center point. Alternatively, the stripes of the horizontal-striped liquid guiding cloth 331 are uniformly arranged horizontally.

[0042] The atomization core casing 30 has a straight cylinder structure. Since the shape of the liquid guiding body 33 is cylindrical, the atomization core casing 30 is designed as a straight cylinder casing to fit the liquid guiding body 33. Thereby, the liquid guiding body 33 can be fixed better, and the liquid guiding body 33 formed by winding a plurality of layers of liquid guiding cloth can be atomizing core casing 30 fixedly attached inside. Also, in some specific embodiments, in order to save costs, the atomization core casing 30 is formed by cutting a metal pipe and has a tubular structure. Also, on the side, a liquid guiding hole 301 for allowing the liquid to enter is opened.

[0043] In some embodiments, the atomizing core casing 30 may adopt a method of opening grooves on the side surface of a tubular metal. This makes it easier to install the liquid guiding member 33 and the heating member 31. Preferably, as shown in FIG. 2, one vertical groove 302 is provided on the side wall of the atomizing core casing 30. Also, the open end of the heating member 31 faces the connection port portions at both lateral ends in a plurality of layers of liquid guiding cloth wound one over another, and the connection port portions at both lateral ends in the plurality of layers of liquid guiding cloth are just engaged and fixed in the vertical groove 302. By doing so, the heating circuit of the heating member 31 can be more closely attached to the liquid guiding member 33, and the atomizing effect is improved. Also, thereby, the problem that the connection port portions at both lateral ends in the plurality of layers of liquid guiding cloth cannot be closely attached to the heating member 31 is avoided. Of course, as shown in FIGS. 1 and 7, grooves may not be opened on the side wall of the atomizing core casing 30, and a plurality of layers of liquid guiding cloth wound one over another may be fixed in the internal space of the atomizer.

[0044] In some embodiments, as shown in FIGS. 3 and 6, at least two vertical grooves 302 are provided on the side wall of the atomizing core casing 30, and the lateral ends in a plurality of layers of liquid guiding cloth wound one over another are engaged and fixed in one of these vertical grooves 302. Alternatively, as shown in FIG. 4, a plurality of sections are provided in the plurality of layers of liquid guiding cloth, and the in the same direction ends of adjacent two sections in the plurality of layers of liquid guiding cloth are both engaged and fixed in one vertical groove 302.

[0045] In some embodiments, the atomizing core casing 30 is a straight cylinder. Also, the lateral ends in the plurality of layers of liquid guiding cloth are butted one by one layer by layer to form a cylindrical structure stacked with a plurality of them. Alternatively, the entire lateral ends in the plurality of layers of liquid guiding cloth are abutted to form an integral cylindrical structure. Thereby, the cylindrical liquid guiding body 33 is fixed in the internal space of the straight cylinder atomizing core casing 30.

[0046] In some embodiments, the vertical stripe liquid guiding cloth 332 is woven from linen-cotton fibers, and the horizontal stripe liquid guiding cloth 331 is woven from spunlace non-woven fabric fibers. Since linen-cotton fibers can withstand high temperatures, the contact portion with the heating member 31 is less likely to carbonize, and the service life is longer. Also, the vertical stripes are provided to conform to the heating circuit structure of the heating member 31. Thereby, by making it possible to slightly insert the heating member 31 into the vertical stripe liquid guiding cloth 332 in the vertical direction, the contact area is increased. Also, the non-woven fabric is adopted because the non-woven fabric has excellent liquid guiding performance. If it is provided outside the liquid guide 33, the tobacco liquid can be guided to the inner heating member 31 more quickly. Also, the horizontal stripes are adopted because the horizontal stripes have minute grooves or minute protrusions in the horizontal direction. By doing so, large capillary gaps are formed in the minute grooves or minute protrusion portions of the horizontal stripe liquid guiding cloth 331. Since the transmission speed of the liquid along the direction of the minute grooves is higher than that in other directions, liquid guiding holes 301 the liquid can be guided better in the circumferential direction. Thereby, the liquid supply in the columnar liquid guide 33 becomes uniform.

[0047] In some embodiments, the lower part of the electrode 32 is bent and closely adheres to the inner wall of the atomization core casing 30. The shape of the fixing member 34 conforms to the atomization core casing 30, and the electrode 32 is pressed and fixed by the fixing member 34. Alternatively, the fixing member 34 is an elastic member, and the electrode 32 is firmly pressed by the fixing member 34 and fixed to the atomization core casing 30.

[0048] In some embodiments, concave grooves are provided on the outer wall of the fixing member 34. The electrode 32 can just be engaged in the concave grooves, and the fixing member 34 is fixed in the atomization core casing 30. Alternatively, through fixing holes are provided in the fixing member 34, and the electrode 32 is inserted and fixed in the fixing holes.

[0049] In Example 2, in some embodiments, as shown in FIG. 19, the heating atomization mechanism is provided with the heating atomization core described in Example 1 within the atomizer casing 20. The upper and lower portions of the atomizer casing 20 are respectively sealed by an upper closing member 21 and a lower closing member 23. A liquid storage chamber is provided between the heating atomization core and the atomizer casing 20, and a liquid storage wick 22 for storing the tobacco liquid is provided within the liquid storage chamber. The reason for providing the upper closing member 21 and the lower closing member 23 on the atomizer casing 20 for sealing is to prevent the leakage of the tobacco liquid within the liquid storage chamber. During operation, the tobacco liquid within the liquid storage device flows to the liquid guiding hole 301 of the atomizer casing 20, is guided to the heating atomization core, and is heated and atomized to form atomized vapor. Since conventional technologies can be adopted for other structures of the heating atomization mechanism, no further detailed description will be provided here.

[0050] In Example 3, as shown in FIG. 20, the heating atomizer includes the heating atomization mechanism described in Example 2. A gas guiding tube 11 is provided at the center of the heating atomization mechanism. One end of the gas guiding tube 11 communicates with the heat generating member 31 of the heating atomization core, and the other end communicates with the mouthpiece 10. The vapor atomized by the heat generating member 31 is led out from within the gas guiding tube 11 to the mouthpiece 10. During the operation of the heating atomizer, the tobacco liquid is heated by the heat generating member 31 to form atomized vapor, flows to the mouthpiece 10 via the gas guiding tube 11, and is finally inhaled by the user. Since conventional technologies can be adopted for other structures of the heating atomizer, no further detailed description will be provided here.

[0051] In Example 4, as shown in FIG. 21, the electronic atomization device includes the upper heating atomizer described in Example 3, the power supply device 4 in the central part, and the control device 5 at the bottom. The power supply device 4 is electrically connected to the heating atomizer and the control device 5 respectively. During the operation of the electronic atomization device, the control device 5 operates to control the activation of the power supply device 4, so that the power supply device 4 supplies electrical energy to the heating atomizer.
