Description

Technical Field

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

Background Art

[0002] An electronic atomization device is a device that heats a liquid using electricity to reach the boiling point of the liquid and convert it into vapor, and is currently widely used in the fields of electronic cigarettes and beauty medicine.

[0003] An electronic atomization device includes an atomizer. The core of the atomizer is an atomization core. As shown in FIG. 1, generally, the atomization core includes a liquid guide 100 and a heating element 200 that are combined with each other. Among them, a hard liquid guide material of a porous ceramic system is widely used because it is easy to assemble. Usually, the liquid guide 100 has a block structure, and generally supplies liquid from the side surface (the part indicated by reference numeral 101 or 102), and a heating element 200 is provided on the bottom surface (atomization surface) to heat the atomization liquid.

[0004] The aerosol formed by atomization by heating is led out from the atomizer through the circumferential side surface of the liquid guide 100 and inhaled by the consumer. In this case, since the flow path of the aerosol becomes long, the temperature drops during the flow process, which changes the inhalation feeling, and as a result, some aerosols may condense. This deteriorates the consistency of the inhalation feeling during atomization, and inhaling the condensate is also not good for the body. In addition, since the liquid guide 100 arranged in the vertical direction supplies liquid from the side surface, there is a problem that liquid leakage is likely to occur.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The technical problem to be solved by the present invention is to provide an atomization device and its atomization core.

Means for Solving the Problems

[0006] The technical solution employed by this invention to solve the technical problems is as follows:

[0007] That is, it constitutes an atomizing core. The atomizing core includes a guide liquid and a heating element. The guide liquid is provided with airflow holes that penetrate in the longitudinal direction. The guide liquid is further provided with at least one liquid storage groove. The liquid storage groove is provided on the outer circumference of the airflow holes. The liquid storage groove includes at least one first sub-liquid storage groove and at least one second sub-liquid storage groove. The first sub-liquid storage groove and the second sub-liquid storage groove are in communication with each other.

[0008] An atomizing surface is formed on the wall surface where the airflow hole and the second sub-liquid storage groove face each other, and the heating element is provided on the atomizing surface.

[0009] In some embodiments, the depth of the first sub-reservoir is less than the depth of the second sub-reservoir, and the width of the longitudinal cross-section of the first sub-reservoir is equal to the width of the longitudinal cross-section of the second sub-reservoir.

[0010] In some embodiments, the depth of the first sub-reservoir is smaller than the depth of the second sub-reservoir, and the width of the longitudinal cross-section of the first sub-reservoir is larger than the width of the longitudinal cross-section of the second sub-reservoir.

[0011] In some embodiments, the reservoir includes two first sub-reservoirs and one second sub-reservoir. Both ends of the second sub-reservoir are connected to and communicate with the two first sub-reservoirs.

[0012] In some embodiments, the number of liquid storage grooves is at least two. At least two of the liquid storage grooves are provided at intervals around the outer circumference of the airflow hole.

[0013] In some embodiments, the wall surface facing the airflow hole and the second sub-liquid storage groove is an arcuate or flat surface.

[0014] In some embodiments, the heating element includes a heating portion and at least two electrode portions connected to the heating portion. The heating portion is attached to or fitted onto the atomizing surface, and the ends of at least two electrode portions are attached to or fitted onto the guide liquid.

[0015] In some embodiments, a receiving groove is provided at the bottom of the fluid guide.

[0016] In some embodiments, the width of the receiving groove is 0.1 to 0.8 mm.

[0017] In some embodiments, the cross-section of the receiving groove has a C-shaped structure, a U-shaped structure, or a straight-line structure.

[0018] In some embodiments, the fluid guide is at least one of porous ceramics, foamed metals, or porous glass.

[0019] The present invention further comprises an atomizing apparatus including the atomizing core described in any of the above embodiments. [Effects of the Invention]

[0020] The present invention provides the following beneficial effects. Specifically, the atomizing core includes a guide liquid and a heating element. A vertically penetrating airflow hole is provided in the center of the guide liquid. The guide liquid is further provided with at least one liquid storage groove. The liquid storage groove is provided on the outer circumference of the airflow hole. The liquid storage groove includes at least one first sub-liquid storage groove and at least one second sub-liquid storage groove. The first sub-liquid storage groove and the second sub-liquid storage groove are in communication. An atomizing surface is formed on the wall surface where the airflow hole and the second sub-liquid storage groove face each other, and a heating element is provided on the atomizing surface. The airflow hole is provided at a central position of the guide liquid close to the air inlet of the atomizing device. Because the flow path of the aerosol generated by the atomizing core is short, it is less likely that the vaping experience will be affected by a drop in temperature, and the vaping experience will be closer to the original taste of the atomizing liquid. Furthermore, since aerosol condensation due to temperature decrease during the flow process can be effectively avoided, the situation in which the generated condensate flows with the aerosol and is inhaled by the consumer can be prevented. In addition, the situation in which the condensate damages the atomizing device can be prevented, thus effectively extending the service life of the atomizing device. Moreover, since the guide liquid is supplied from the top, liquid leakage and spillage are less likely to occur compared to when the liquid is supplied from the side.

It should be understood that the following drawings are merely examples of some embodiments of the present invention and should not be considered limiting in scope.

[0023] For a clearer understanding of the technical features, objectives, and effects of the present invention, the specific embodiments of the present invention will be described in detail with reference to the drawings. In the following description, it should be understood that the directions or positional relationships indicated by "front", "rear", "upper", "lower", "left", "right", "vertical", "horizontal", "ceiling", "bottom", "inner", "outer", "beginning", "end", etc. are the directions or positional relationships based on the illustrations, and the configurations and operations in specific directions are only for the convenience of describing this technical solution, and do not indicate that the indicated devices or members must have a specific direction. Therefore, it should not be construed as limiting the present invention.

[0024] Furthermore, it should be explained that, unless otherwise explicitly specified and limited, terms such as “attach,” “connect,” “bond,” “fix,” and “install” should be interpreted broadly. For example, a connection may be fixed, removable, or form a single unit. It may also be mechanical or electrical. It may be a direct connection, an indirect connection via an intermediate medium, internal communication between two members, or an interaction relationship between two members. Also, when one member is said to be “above” or “below” another member, that member can be located on the other member “directly” or “indirectly,” and there may be one or more intermediate members. In addition, terms such as “first,” “second,” and “third” are merely for convenience in describing this technical solution and should not be interpreted as explicitly or implicitly indicating relative importance, nor as suggesting the number of technical features being pointed out. Therefore, when features such as "first," "second," and "third" are defined, they may explicitly or implicitly include one or more such features. A person skilled in the art can interpret the specific meaning of the above terms in the present invention according to the specific circumstances.

[0025] In the following description, specific details such as particular systems, structures, and techniques are presented for illustrative purposes, not for limitation, so that embodiments of the present invention may be fully understood. However, as will be apparent to those skilled in the art, the present invention can also be realized in other embodiments in which these specific details are absent. Furthermore, in other circumstances, detailed descriptions of well-known systems, apparatus, electrical circuits, and methods are omitted so as not to hinder the description of the present invention by unnecessary details.

[0026] Referring to Figure 1, the present invention presents an atomizing core 10. The atomizing core 10 includes a guide liquid 11 and a heating element 12. The guide liquid 11 is provided with vertically penetrating airflow holes 111. The guide liquid 11 is further provided with at least one liquid storage groove 112. The liquid storage groove 112 is provided on the outer circumference of the airflow holes 111. The liquid storage groove 112 includes at least one first sub-liquid storage groove 1121 and at least one second sub-liquid storage groove 1122. The first sub-liquid storage groove 1121 and the second sub-liquid storage groove 1122 are in communication.

[0027] An atomizing surface A is formed on the wall surface where the airflow hole 111 and the second sub-liquid storage groove 1122 face each other, and a heating element 12 is provided on the atomizing surface A.

[0028] To make it clear, the airflow holes 111 are located at the center of the guide liquid 11, close to the air inlet of the atomizing device. Because the flow path of the aerosol generated by the atomizing core 10 is short, it is less likely that the vaping experience will be affected by a drop in temperature, and the vaping experience will be closer to the original taste of the atomizing liquid. Furthermore, since the condensation of the aerosol due to a drop in temperature during the flow process can be effectively avoided, it is possible to prevent the generated condensed liquid from flowing with the aerosol and being inhaled by the consumer. In addition, it is possible to prevent the condensed liquid from damaging the atomizing device or power supply device, etc., thus effectively extending the service life of the atomizing device.

[0029] Furthermore, the heating element 12 is mainly installed on the wall surface where the airflow hole 111 and the second sub-liquid reservoir 1122 face each other. The heating element 12 primarily heats and atomizes the atomizing liquid in the second sub-liquid reservoir 1122. In the atomizing device, the atomizing liquid in the liquid reservoir chamber first passes through the first sub-liquid reservoir 1121 before being able to enter the second sub-liquid reservoir 1122. Moreover, when the atomizing liquid in the second sub-liquid reservoir 1122 is consumed, the atomizing liquid in the first sub-liquid reservoir 1121 is replenished into the second sub-liquid reservoir 1122. This ensures smooth liquid supply and reduces the likelihood of leakage or seepage.

[0030] Specifically, the fluid guide 11 has a roughly hexahedral structure and has an upper surface and a lower surface that are opposite each other. The fluid storage groove 112 is a non-penetrating groove structure formed so as to be recessed from the upper surface toward the lower surface.

[0031] Referring to Figure 4 or Figure 7, the depth of the first sub-liquid storage groove 1121 is less than the depth of the second sub-liquid storage groove 1122. Furthermore, the width of the longitudinal section of the first sub-liquid storage groove 1121 is equal to the width of the longitudinal section of the second sub-liquid storage groove 1122.

[0032] In some embodiments, the depth of the first sub-liquid reservoir 1121 is less than the depth of the second sub-liquid reservoir 1122. Furthermore, the width of the longitudinal cross-section of the first sub-liquid reservoir 1121 is greater than the width of the longitudinal cross-section of the second sub-liquid reservoir 1122.

[0033] In some embodiments, as shown in Figures 2 and 3, there are at least two liquid storage grooves 112. At least two liquid storage grooves 112 are provided at intervals around the outer circumference of the airflow hole 111.

[0034] In some embodiments, as shown in Figures 5 and 6, the liquid reservoir 112 is provided on the outer circumference of the airflow hole 111. The liquid reservoir 112 may also have a substantially C-shaped or U-shaped structure. The liquid reservoir 112 may include two first sub-liquid reservoirs 1121 and one second sub-liquid reservoir 1122. Both ends of the second sub-liquid reservoir 1122 are connected to and communicate with the two first sub-liquid reservoirs 1121. The atomizing liquid can first pass through the two first sub-liquid reservoirs 1121 before being introduced into the second sub-liquid reservoir 1122.

[0035] In some embodiments, the wall surface where the airflow hole 111 and the second sub-liquid storage groove 1122 face each other is either an arcuate or a flat surface. That is, the atomizing surface A may have an arcuate structure (shown in Figure 3) or a flat structure (shown in Figure 6).

[0036] In some embodiments, a receiving groove 113 is further provided at the bottom of the fluid guide 11. The width of the receiving groove 113 is 0.1 to 0.8 mm. Preferably, the cross-section of the receiving groove 113 has a C-shaped structure, a U-shaped structure, or a straight-line structure. The structure and size of the receiving groove 113 can be selected and installed according to the actual needs and are not specifically limited herein.

[0037] Specifically, the storage groove 113 avoids the liquid storage groove 112 in order to avoid direct communication with the liquid storage groove 112. The storage groove 113 may be installed with its opening facing downwards. The groove width of the storage groove 113 may be 0.1 to 0.8 mm, for example, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, or 0.8 mm may be selected. The groove depth of the storage groove 113 may be 0.5 to 2 mm, for example, 0.5 mm, 1 mm, 1.5 mm, or 2 mm.

[0038] As can be understood, in some special environments, for example, when the outside air pressure is low, if the air pressure inside the atomizer becomes higher than the outside air pressure, a pressure difference will exist between them. Then, the gas inside the atomizer will expand, and some of the atomizing liquid in the guide liquid 11 may be pushed out of the guide liquid 11. In response to this, the internal space of the containment groove 113 can form a containment space that can accommodate this portion of the atomizing liquid. Furthermore, since the groove width of the containment groove 113 is relatively narrow, the atomizing liquid can be located in the containment groove 113 without leaking out of the guide liquid 11 due to capillary tension. This makes it possible to achieve good liquid leakage prevention and liquid leakage prevention effects.

[0039] In some embodiments, the heating element 12 includes a heating portion 121 and at least two electrode portions 122 connected to the heating portion 121. The heating portion 121 is attached to or fitted onto the atomizing surface A, and the ends of at least two electrode portions 122 are attached to or fitted onto the guide liquid 11. Preferably, the heating element 12 has a planar structure. A planar structure is relatively flat and resistant to deformation, and makes bonding with and processing with the guide liquid 11 easier. Furthermore, when the ends of the electrode portions 122 are embedded in the bottom of the guide liquid 11, it is possible to avoid instability of the circuit contact due to factors such as the electrode portions 122 being pulled, thereby improving the stability of the atomizer's operation.

[0040] In some embodiments, the fluid guide 11 is at least one of porous ceramic, foamed metal, or porous glass. Specifically, the fluid guide 11 may be made of porous ceramic. As can be understood, the material used to manufacture the fluid guide 11 may be a porous material having a capillary effect due to micropores, such as foamed metal, porous glass, or rigid fiberglass pipe.

[0041] The heating element 12 generates an aerosol that the user can directly inhale by heating the atomizing liquid stored in the second sub-liquid reservoir 1122 after power is applied. The heating element 121 may be a sheet-shaped heating mesh. The heating element 121 is attached to and fixed to the atomizing surface A. The heating element 121 may also be a heating wire that can be bent to form a tray shape, or a grid-shaped heating sheet. The heating element 121 may also be sintered to form an integral structure with the guide liquid 11 and attached to the atomizing surface A. In some embodiments, the heating element 121 may further be a heating circuit, heating trajectory, heating coating layer, or heating film formed on the atomizing surface A. The structure and shape of the heating element 121 can be varied and selected as needed. The heating mesh, heating wire, heating sheet, heating circuit, heating trajectory, heating coating layer, or heating film described above are provided corresponding to the second sub-liquid reservoir 1122. This minimizes the distance between the second sub-liquid reservoir 1122 and the heating element 121, allowing the atomizing liquid, such as tobacco liquid, to quickly reach the heating element 121 and be atomized. Furthermore, the electrode 122 may be a sheet-like structure, or it may be a columnar or rod-like structure.

[0042] Preferably, the material of the heating element 12 may be a metallic material, a metallic alloy, graphite, carbon, a conductive ceramic, or a composite material of a metallic material and other ceramic materials having appropriate impedance. Metals or alloy materials having appropriate impedance include at least one of nickel, cobalt, zirconium, titanium, nickel alloys, cobalt alloys, zirconium alloys, titanium alloys, nickel-chromium alloys, nickel-iron alloys, iron-chromium alloys, iron-chromium aluminum alloys, titanium alloys, iron-manganese aluminum alloys, or stainless steel.

[0043] Referring to Figure 8, the present invention further discloses an atomizing device applicable to electronic cigarettes. The atomizing device may include an atomizing core 10. It may also include an atomizing case 20 and a mounting unit 30. The atomizing core 10 is mounted within the mounting unit 30 and together with the atomizing case 20. The atomizing case 20 may be provided with an air passage and a liquid storage space (liquid storage chamber). The atomizing liquid in the liquid storage chamber is introduced into the liquid storage groove 112 of the atomizing liquid 11 through the liquid passage provided in the mounting unit 30. The air passage is in communication with an airflow hole 111. The aerosol generated by the atomizing core 10 is discharged from the atomizing device through the air passage and provided to the consumer.

[0044] As can be understood, the above embodiments merely illustrate preferred embodiments of the present invention, and although the description is relatively specific and detailed, this should not be interpreted as limiting the scope of the rights of the present invention. It should be noted that those skilled in the art can freely combine the above technical characteristics and make some modifications and improvements, provided that they do not depart from the concept of the present invention, and all of these fall within the scope of protection of the present invention. Therefore, any equivalent modifications and additions made within the scope of the claims of the present invention shall all fall within the scope covered by the claims of the present invention.
