Embodiments of the present invention

In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

It should be noted that when a component is referred to as being "fixed on" or "disposed on" another component, it may be directly on the other component or indirectly on the other component. When a component is referred to as being "connected to" another component, it may be directly or indirectly connected to the other component. The orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances. The terms "first" and "second" are only used for the purpose of convenience of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. The meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

In a traditional atomizer core, the heating level of the heating element for forming the atomized gas is consistent or as consistent as possible, and thus the overall temperature of the atomizer core is relatively consistent, and its temperature should be higher than the atomization temperature of the atomizing liquid such as the e-liquid. However, the atomizer core installed in the atomizing chamber of the atomizing device does not have the oil evenly covering the surface of the atomizer core, but enters the atomizing chamber through the liquid inlet hole on the atomizing chamber, and gradually penetrates from the proximal end of the atomizer core close to the liquid inlet hole to the distal end. In this way, the oil always atomizes and rises at the proximal end of the atomizer core, and the amount of oil at the distal end is relatively small. Once the liquid supply is insufficient, the distal end of the atomizer core with too high a temperature will dry burn and burn.

In order to solve the above problems, the present application provides a heating component 100, and performs zone heating on the heating component 100, that is, ensure that the temperature of the proximal end of the heating component 100 close to the oil inlet hole of the atomization device is lower than the temperature of the distal end of the heating component 100 away from the oil inlet hole of the atomization device, so that the oil can penetrate and fill the entire heating component 100, so as to ensure that the supply amount of the oil meets the atomization amount of the oil, thereby reducing the occurrence of dry burning and core burning.

Specifically, please refer to Figures 1 and 3. The embodiment of the present application provides a heating component 100 including an atomizing carrier 10 and a heating element 20. The atomizing carrier 10 is used to absorb atomized liquid such as oil, and the heating element 20 is used to heat the atomizing carrier 10, which is electrically connected to the power supply of the external device.

Among them, the atomizing carrier 10 has a preheating part 11 and an atomizing part 12, and the preheating part 11 and the atomizing part 12 are both in contact with the oil. It can be understood that the preheating part 11 is close to the oil inlet hole of the atomizing device and belongs to the proximal end of the atomizing carrier 10, and the atomizing part 12 is far away from the oil inlet hole of the atomizing device and belongs to the distal end of the atomizing carrier 10. In this way, the oil first contacts the preheating part 11 of the atomizing carrier 10, and then is gradually transmitted to the atomizing part 12. In addition, the preheating part 11 is for preheating the atomized liquid such as the oil, and its heating temperature should be lower than the atomization temperature of the oil, and the atomizing part 12 is the part where the oil is atomized, and its heating temperature should be higher than or equal to the atomization temperature of the oil.

The heating element 20 includes a heating part 21 and a heat conducting part 22. The heating power of the heating part 21 is greater than that of the heat conducting part 22. The heating part 21 is arranged on the atomizing part 12, and the heat conducting part 22 is arranged on the preheating part 11. It can be understood that the difference in the heating power of the two heating parts leads to different working temperatures of the atomizing part 12 and the preheating part 11, thereby achieving preheating of the oil, increasing the fluidity of the oil, and maintaining good transmission properties. After the oil is preheated, it can be better transported to the atomizing part 12 of the atomizing carrier 10 for heating and atomization.

The heating power of the two heating parts of the heating element 20 is related to their own resistance and electrical connection relationship. That is, the heating part 21 and the heat conducting part 22 can be connected in series or in parallel according to the use requirements. At the same time, under the corresponding electrical connection relationship, the resistance of the heating part 21 is not equal to the resistance of the heat conducting part 22.

For example, when the heating material is the same, the differences in thickness, width, and wiring patterns of the two heating parts may ultimately lead to different resistance values of the two heating parts, and further lead to different heating powers of the two heating parts.

For example, when the width of the heating part 21 is smaller than the width of the heat-conducting part 22, the resistance value of the heating part 21 is greater than the resistance value of the heat-conducting part 22, and when the heating area of the heating part 21 is smaller than the heating area of the heat-conducting part 22, the heating power of the heating part 21 is greater than the heating power of the heat-conducting part 22.

For example, if the thickness of the heating portion 21 is smaller than that of the heat conducting portion 22 , the resistance value of the heating portion 21 is smaller than that of the heat conducting portion 22 , and the heating power of the heating portion 21 is greater than that of the heat conducting portion 22 .

For example, if the spacing between the heating wires of the heating portion 21 is smaller than the spacing between the heating wires of the heat-conducting portion 22 , then the heating power of the heating portion 21 is greater than the heating power of the heat-conducting portion 22 .

For example, when the shapes and structures of the two heating parts are the same, the materials of the two heating parts can be different, which leads to differences in the resistance values of the two heating parts.

The heating component 100 provided in the present application has a preheating part 11 and an atomizing part 12. The preheating part 11 is used to preheat the atomizing liquid such as the e-liquid, that is, the e-liquid is raised from room temperature to a preset temperature, and the atomizing part 12 is used to atomize and rise the atomizing liquid such as the e-liquid, that is, the e-liquid is heated to reach the atomizing temperature, and then the atomization phenomenon occurs. Specifically, the heating power of the heating part 21 and the heat conducting part 22 of the heating element 20 are set differently. For example, the heating power of the heating part 21 is greater than the heating power of the heat conducting part 22, so that the temperature on the atomizing part 12 and the preheating part 11 is differentiated. Then, at the preheating part 11, the heat conducting part 22 can heat and atomize a small amount of atomizing medium with a lower atomizing temperature, that is, the atomizing medium can be preheated. At the same time, the components with a lower atomizing temperature in the atomizing medium can be atomized to avoid being cracked in the atomizing part 12 with a higher temperature, thereby enriching the components of the aerosol formed by atomization and improving the user's inhalation taste. In summary, when the oil soaks the heating component 100 of the present application, the preheating unit 11 can preheat the oil to increase the fluidity of the oil and ensure that the oil is evenly distributed on the heating component 100, thereby avoiding dry burning and core sticking caused by insufficient oil supply.

Please refer to Figure 1 or Figure 3. In one embodiment, the atomizing carrier 10 has a first end 10a and a second end 10b that are relatively arranged, and a peripheral side surface connected to the first end 10a and the second end 10b. A groove structure 10c that runs through the first end 10a and the second end 10b is formed on the peripheral side surface. The atomizing portion 12 is formed at the inner wall of the groove structure 10c, and the preheating portion 11 is formed at other inner walls of the groove structure 10c that are different from the atomizing portion 12, and/or, the preheating portion 11 can also be formed on the peripheral side surface. It can be understood that when the atomizing carrier 10 is in the atomizing chamber of the atomizing device, the plane where the first end 10a and the second end 10b are located is perpendicular or approximately perpendicular to the atomization rising direction of the atomized gas. The peripheral side surface is parallel or approximately parallel to the inner wall of the atomizing chamber, thereby ensuring that the atomizing carrier 10 can be fixed in the atomizing chamber. The groove structure 10c is enclosed with the inner wall of the atomizing chamber to form a groove structure. In terms of the setting position, when the groove structure 10c can correspond to the oil inlet hole of the atomizing device, then the atomizing part 12 and the preheating part 11 can be set at different groove walls of the groove structure 10c. Alternatively, when the peripheral side of the atomizing carrier 10 corresponds to the oil inlet hole of the atomizing device, then the atomizing part 12 is formed at the groove structure 10c, and the preheating part 11 is formed at the peripheral side.

Here, the shape of the groove structure 10c is not limited, and is subject to the requirement of being able to satisfy the passage of the atomized gas. For example, on a plane parallel to the first end 10a or the second end 10b, the cross section of the groove structure 10c is square, arc-shaped or irregular. At the same time, in order to ensure that the atomized gas can quickly pass through the groove structure 10c, the groove extension length of the groove structure 10c is the minimum distance between the first end 10a and the second end 10b, so that the atomized gas can quickly pass through the atomizing carrier 10, reducing the loss during the atomization and rising process.

Please refer to Figures 2 and 7. In one embodiment, the groove structure 10c has a bottom wall 10c1 and two side walls 10c2 arranged opposite to each other. It can be understood that in this embodiment, on a plane parallel to the first end 10a or the second end 10b, the cross section of the groove structure 10c is square, and thus has a bottom wall 10c1 and two side walls 10c2 arranged opposite to each other.

Specifically, the atomizing portion 12 is formed at the bottom wall 10c1, and the preheating portion 11 is formed at at least one of the side walls 10c2. Then, the bottom wall 10c1 of the groove structure 10c is used to install the heating portion 21, and one or both side walls 10c2 are used to install the heat conducting portion 22. In this way, the distance between the atomizing portion 12 and the preheating portion 11 is small, the time from preheating to atomization of the oil is faster, and the oil flows to form a lower oil.

Alternatively, the atomizing portion 12 is formed at the bottom wall 10c1 and one of the side walls 10c2, and the preheating portion 11 is formed at the other side wall 10c2. Then, the heating portion 21 is distributed on the bottom wall 10c1 and one of the side walls 10c2 of the groove structure 10c, and the heat-conducting portion 22 is arranged on the other side wall 10c2 of the groove structure 10c. At this time, the oil adheres to or enters the atomizing carrier 10 from one side wall 10c2 of the groove structure 10c having the heat-conducting portion 22, and then enters the bottom wall 10c1 or the other side wall 10c2 of the groove from the side wall 10c2.

Please refer to Figures 4, 5 and 7. In one embodiment, the groove structure 10c has a bottom wall 10c1 and two side walls 10c2 disposed oppositely. Similarly, in this embodiment, on a plane parallel to the first end 10a or the second end 10b, the cross section of the groove structure 10c is square, and thus has a bottom wall 10c1 and two side walls 10c2 disposed oppositely.

The atomizing portion 12 is formed at the bottom wall 10c1 and/or any one of the side walls 10c2. It can be understood that the heating portion 21 can be arranged on the bottom wall 10c1, or the heating portion 21 can be arranged on one or both of the side walls 10c2, or the heating portion 21 can also be arranged on the bottom wall 10c1 and one of the side walls 10c2, or the heating portion 21 can be arranged on the bottom wall 10c1 and both of the side walls 10c2. That is, the entire groove structure 10c is only provided with the heating portion 21, regardless of the structural form of the groove structure 10c, the cross-section of the groove structure 10c can also be other shapes, and at the same time, the heating portion 21 is arranged on any one or more inner walls of the groove structure 10c.

The preheating part 11 is formed on the peripheral side. That is, the heat conducting part 22 is arranged on the peripheral side. In particular, when the oil enters or adheres to the peripheral side of the atomizing carrier 10, the entire atomizing carrier 10 can be heated up faster, and the heating effect can last longer.

Please refer to Figure 1 or Figure 3. In one embodiment, the two opposite peripheral side surfaces are both recessed inward to form a groove structure 10c that passes through the first end 10a and the second end 10b. It can be understood that, generally, the atomization carrier 10 is a cubic structure. For example, on a plane parallel to the first end 10a or the second end 10b, the cross-section of the atomization carrier 10 is square, elliptical or circular, and the two groove structures 10c are not limited to form a concave shape in a direction parallel to the first end 10a or the second end 10b, and the size of the concave shape of the two groove structures 10c is also not limited.

For example, in order to facilitate the laying of the heating element 20 and to fully contact the heating part of the heating element 20, the groove bottom surface of the groove structure 10c is a plane to meet the need for full contact with the heating part of the heating element 20. At the same time, the side wall 10c2 of the groove structure 10c can also be used for laying the heating part of the heating element 20. Of course, according to the shape design of the heating part of the heating element 20, the groove bottom surface of the groove structure 10c is also an arc surface, or a pit or a protrusion is formed on the groove bottom surface of the groove structure 10c to adapt to the shape structure of the current heating part.

For example, the concave shapes of the two groove structures 10c are the same, and the sizes of the concave shapes are also the same. Alternatively, the concave shapes of the two groove structures 10c are the same, but the sizes of the concave shapes of the two groove structures 10c are different.

Please refer to Figures 1 and 6. In one embodiment, the heating element 20 further includes a first connecting portion 24, which is used to connect in series the heating portion 21 at the corresponding groove structure 10c. The first connecting portion 24 is embedded in the atomization carrier and passes through the bottom walls of the corresponding two groove structures 10c.

It can be understood that the first connection part 24 can realize the serial connection of the heating parts 21 at the corresponding two groove structures 10c, so that the power supply circuit of the entire heating element 20 is simpler. At the same time, the use of the atomizing carrier through the setting can further improve the connection stability between the heating element 20 and the atomizing carrier 10, and when the first connection part 24 determines a suitable length, the first connection part 24 can be used to pull the two heating parts 21, so that the heating part 21 and the inner wall of the corresponding groove structure 10c can be more closely attached, thereby improving the heat transfer efficiency of the heating part 21 to the atomizing carrier 10.

Please refer to Figure 7. In one embodiment, the atomization carrier 10 includes a carrier belly 13 and carrier wings 14 connected to opposite sides of the carrier belly 13. The opposite inner walls of the two carrier wings 14 and the outer wall of the carrier belly 13 are surrounded to form two oppositely arranged groove structures 10c.

It can be understood that in the cross-sectional direction, the cross-section of the atomizing carrier 10 is an "I"-shaped structure, which has good compressive and bending strength. At the same time, the groove structure 10c is formed on the peripheral side of the atomizing carrier 10, which has a higher liquid storage capacity, and the transmission path of the atomized medium from the carrier wing 14 to the carrier belly 13 is also shorter, and the transmission time is shorter, thereby avoiding the dry burning problem caused by insufficient liquid supply.

The thickness T2 of the carrier belly 13 is greater than the thickness T1 of the carrier wing 14. The heating portion 21 is arranged on the carrier belly 13, and the outer wall surface of the carrier wing 14 is the contact surface between the atomization carrier 10 and the atomization medium. In this way, the carrier wing 14 first contacts the atomization medium, and is transferred to the carrier belly 13 through the carrier wing 14. The carrier belly 13 is heated and heated by each heating portion 21, and the atomization medium is atomized at the carrier belly 13 to form an aerogel, which also makes the amount of atomization medium in the carrier belly 13 less, so that the atomization medium has a tendency to be transmitted from the carrier wing 14 to the carrier belly 13, so as to ensure that the atomization medium at the carrier belly 13 can be continuously supplied. At the same time, on the basis of ensuring the overall structural strength of the atomizing carrier 10, the liquid conducting area of the atomizing carrier 10 is larger, and the area of the inner surface of the groove structure 10c is relatively reduced. Here, the area of the inner surface of the groove structure 10c is the atomization area of the atomizing carrier 10. In this way, on the whole, the liquid conducting area of the atomizing carrier 10 is larger than the atomization area, which can also avoid the occurrence of the "dry burning" phenomenon caused by insufficient liquid supply.

Optionally, according to the size of the atomizing device, the value ranges of T1 and T2 may be: T2 ≥ 1.5 mm, T1 ≥ 0.8 mm. It can be understood that the thickness of the carrier belly 13 is greater than or equal to 1.5 mm, and the thickness of the carrier wing 14 is greater than or equal to 0.8 mm.

Specifically, as shown in FIG. 1 or FIG. 3, on a plane parallel to the first end 10a or the second end 10b, the cross section of the atomizing carrier 10 is square, that is, the atomizing carrier 10 has four peripheral side surfaces, two of which are provided with a groove structure 10c respectively on the two opposite peripheral side surfaces, and the cross section of the groove structure 10c is also square, so that after the groove structure 10c is provided, the final cross-sectional shape of the atomizing carrier 10 is an "I" shape, and the atomizing carrier 10 of the I-shaped structure has high structural strength, especially in the two peripheral side directions where the groove structure 10c is not provided, the atomizing carrier 10 has a higher compressive strength. At the same time, compared with the internal groove structure of the atomizing carrier 10, the groove structure 10c is provided on the two opposite peripheral side walls 10c2 of the atomizing carrier 10, and the gas volume of the atomizing gas transmitted per unit time is higher.

In one embodiment, the preheating portion 11 is also formed at the first end 10a and/or the second end 10b. It can be understood that the heat conducting portion 22 is also arranged on the first end 10a, or, arranged on the second end 10b, or, arranged on the first end 10a and the second end 10b. Similarly, the preheating portion 11 is on the outer peripheral side of the atomizing carrier 10, and when the oil enters or adheres from the peripheral side of the atomizing carrier 10, the entire atomizing carrier 10 can be heated up faster, and at the same time, the heating effect lasts longer.

Please refer to Fig. 6, in one embodiment, the heating element 20 further includes a second connection portion 23, and the heat conducting portion 22 is connected to the heating portion 21 via the corresponding second connection portion 23. It can be understood that one end of the heating portion 21 away from the second connection portion 23 and one end of the heat conducting portion 22 away from the second connection portion 23 are respectively connected to the positive and negative electrodes of the power supply to form a series circuit.

For example, the ends of the heating part 21 and the heat conducting part 22 on the same side are respectively connected to the opposite ends of the second connecting part 23, so that the entire heating part has a U-shaped structure. The second connecting part 23 can be connected to the atomizing carrier 10 by passing through the atomizing carrier 10, or can be connected to the atomizing carrier 10 by being fixed on the first end 10a or the second end 10b, or can be wound around the peripheral side of the atomizing carrier 10 to meet the requirements of connecting to the atomizing carrier 10.

Please refer to Figures 3 to 5. In one embodiment, the atomization part 12 is formed at the groove structure 10c, the preheating part 11 is formed at the peripheral side, the second connection part 23 penetrates the atomization carrier 10, and the opposite ends of the second connection part 23 are respectively connected to the heating part 21 and the heat-conducting part 22. It can be understood that in this embodiment, the number of the heating parts 21 and the number of the groove structures 10c are both two, and the two heating parts 21 are respectively arranged at the corresponding groove structures 10c; the number of the heat-conducting parts 22 is four, and each two are a group, which are respectively arranged on the corresponding peripheral side, and the atomization carrier 10 is penetrated by the second connection part 23, and the two heat-conducting parts 22 on the opposite peripheral side are connected to the same heating part 21 through the second connection part 23. In this way, when the oil enters or adheres to the peripheral side of the atomization carrier 10, the entire atomization carrier 10 can be heated up faster, and at the same time, the heating effect lasts longer.

In one embodiment, the heating power of the second connection part 23 is less than the heating power of the heat conducting part 22. It can be understood that the second connection part 23 is used to realize the electrical series connection between the heating part 21 and the heat conducting part 22, so the second connection part 23 itself will also generate heat after being powered on. In order to reduce the power consumption of the second connection part 23 and ensure that the heat is concentrated on the heating part 21 and the heat conducting part 22, the heating power of the second connection part 23 should be reduced.

For example, the second connection portion 23 and the heating portion may be made of a material with the same resistance. In this case, the second connection portion 23 is thinner, and the thinner the second connection portion 23 is, the smaller the heating power is.

For example, the second connection part 23 can also be made of a material with different resistance from the heating part. In this case, the resistance of the material of the heating part is large, and the resistance of the material of the second connection part 23 is small. In this way, the heating power of the second connection part 23 can be smaller than the heating power of the heating part.

In one embodiment, the heating part 21 and/or the heat conducting part 22 are sheet structures. It can be understood that the atomizing part 12 or the preheating part 11 of the atomizing carrier 10 is mostly a planar structure, the heating part 21 is a sheet structure, or the heat conducting part 22 is a sheet structure, or the heating part 21 and the heat conducting part 22 are both sheet structures. That is, the sheet structure is more able to contact with the plane of the atomizing part 12 or the preheating part 11, the contact area between the two is larger, and the working heat of the heating part can be transferred to the atomizing carrier 10 faster.

In one embodiment, the manufacturing process of the sheet structure can be selected according to actual needs. For example, the sheet structure is a metal sheet, and the required shape structure is manufactured by stamping or etching, and then the metal sheet is fixed on the surface of the atomizing part 12 or the preheating part 11 of the atomizing carrier 10. Alternatively, the sheet structure is a conductive coating. That is, the surface of the atomizing part 12 or the preheating part 11 of the atomizing carrier 10 is directly coated by a spraying process.

In some embodiments, the atomizing carrier 10 is made of, but not limited to, porous ceramics, porous glass, cotton, fiber, or a composite material thereof. Preferably, the atomizing carrier 10 is made of porous ceramics, and the heating element 20 is an etched metal sheet, wherein the atomizing carrier 10 and the heating element 20 can be sintered into one.

Please refer to Figure 6. In one embodiment, a hole structure 22a for storing atomized liquid is provided on the heat conducting part 22. It can be understood that, firstly, the hole structure 22a can improve the adhesion of atomized liquid such as oil, increase the residence time of the oil on the heat conducting part 22, always keep the oil in full contact with the preheating part 11 of the atomizing carrier 10, and also avoid the phenomenon of dry burning of the oil at the heat conducting part 22; secondly, the hole structure 22a can reduce the resistance value of the heat conducting part 22, especially when it is made of the same material as the heating part 21, the hole structure 22a can reduce the heating area of the heat conducting part 22.

For example, as shown in FIG6 , the hole structure 22a is a through hole formed in an array on the heat conducting part 22, so that the through hole can increase the time for the atomized liquid such as oil to form and adhere to the heat conducting part 22, ensure that the oil is fully in contact with the preheating part 11 of the atomizing carrier 10, and reduce the occurrence of dry burning. At the same time, the hole structure 22a can reduce the resistance value of the heat conducting part 22.

The embodiment of the present application further provides an atomization device, comprising the above-mentioned heating component 100.

The atomizing device provided in the present application, based on the above-mentioned heating component 100, has the advantages of rapid formation of atomized gas and low probability of occurrence of dry burning, core burning and odor.

In one embodiment, the atomizing device further includes a temperature-controlled resistor and a power supply battery. Among them, the heating part 21 and the heat-conducting part 22 in the heating component 100 are electrically connected to the power supply battery in parallel, and at the same time, the temperature-controlled resistor is connected in series with the heat-conducting part 22, so as to form a partitioned temperature control circuit. The advantage of the partitioned temperature control circuit is that the heating part 21 and the heat-conducting part 22 are connected in parallel, can be independently controlled, do not interfere with each other, and when the heat-conducting part 22 is working, the temperature-controlled resistor connected in series with it also generates heat due to power-on. Once the upper limit temperature of the temperature-controlled resistor is exceeded, the series circuit is short-circuited. At this time, the heat-conducting part 22 cannot be powered on to generate heat and is in a stopped state. In this way, the heat generation of the heat-conducting part 22 can be controlled so that it can preheat the atomization of oil and the like, and the heating temperature is not too high to ensure the utilization efficiency of the power supply battery.

The above are only optional embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
