Description

Technical Field

[0002] See Figure 1 In atomization technology, a heating element and a liquid guide are typically combined to form a heating assembly. The liquid guide conducts the liquid to the heating element for heating and atomization. The liquid guide often uses liquid-guiding cotton or porous ceramic as the guiding element, while the heating element generally consists of a heating wire spirally wound around the outer edge of the liquid-guiding cotton rope. Such heating assemblies are commonly used in e-cigarettes to heat and atomize e-liquid. The airflow passes through the heating assembly and carries the vapor out. However, problems exist: either a burnt taste is easily produced, the flavor of the smoke is not fully realized, or carbon buildup easily forms, affecting the lifespan of the device.

Detailed Implementation

[0046] To provide a clearer understanding of the technical features, objectives, and effects of this invention, specific embodiments are now described in detail with reference to the accompanying drawings. It should be understood that the use of terms such as "front," "rear," "upper," "lower," "left," "right," "longitudinal," "horizontal," "vertical," "horizontal," "top," "bottom," "inner," "outer," "head," and "tail" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings, and refers to construction and operation in a specific orientation. This is merely for the purpose of describing the technical solution and does not indicate that the device or element referred to must have a specific orientation; therefore, it should not be construed as a limitation of the invention. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "install," "connect," "join," "fix," and "set" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. When an element is referred to as being "on" or "below" another element, the element can be located "directly" or "indirectly" on the other element, or there may be one or more intermediary elements. If the terms "first," "second," "third," etc., appear in the text, they are merely for the convenience of describing the technical solution and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0047] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0048] See Figure 2Research has revealed that the problems mentioned in the background technology—either the smoke flavor is not produced or carbon buildup easily forms, affecting service life—are due to the fact that the heating element 41 generates heat in all directions, with little difference in heat distribution. However, the airflow passes through the lower semicircular part of the heating element 41, resulting in uneven temperature distribution because the upper semicircular part generates more heat than the lower semicircular part. To address this, the present invention provides an improved atomizing device heating element with different heating effects in different parts. As for the problem of burnt smell, the reason is that existing heating components typically draw liquid from both ends of the liquid guide 41, with the liquid entering from both ends and reaching the middle position. This long liquid flow path can easily lead to insufficient liquid supply and burnt smell when the heating component is continuously heating.

[0049] See Figure 3-5 In one embodiment of the present invention, the heating element 1 of the atomizing device, which exhibits different heating effects at different locations, is used to heat and atomize liquid. It is tubular in shape with a radial dimension of 1-17 mm, an axial dimension of 2-33 mm, and a wall thickness of 0.02-0.9 mm. The heating element 1 can be a round or square tube. For a square tube, the aforementioned radial dimensions correspond to the width and height, and the axial dimension corresponds to the length. Heating elements of this size typically have suitable resistance and thus provide a good heating effect. The heating element 1 includes two electrode portions 12 respectively disposed at both ends in the axial direction and a heating circuit portion 11 electrically connected between the two electrode portions 12. The heating circuit portion 11 includes a set of first connecting portions 111, a set of second connecting portions 112, a set of third connecting portions 113 and a set of fourth connecting portions 114 arranged in circumferentially in sequence. The set of first connecting portions 111 includes a plurality of first connecting portions 111 distributed axially at intervals. The set of second connecting portions 112 includes a plurality of second connecting portions 112 distributed axially at intervals. The set of third connecting portions 113 includes a plurality of third connecting portions 113 distributed axially at intervals. The set of fourth connecting portions 114 includes a plurality of fourth connecting portions 114 distributed axially at intervals.

[0050] The axial dimensions of the first connecting part 111 and the third connecting part 113 are larger than the axial dimensions of the second connecting part 112 and the fourth connecting part 114. Each first connecting part 111 connects two adjacent second connecting parts 112 and two adjacent fourth connecting parts 114, and each third connecting part 113 connects two adjacent second connecting parts 112 and two adjacent fourth connecting parts 114, so that the first connecting part 111, the second connecting part 112 and the third connecting part 113 are connected to form a first circuit 11a, and the third connecting part 113, the fourth connecting part 114 and the first connecting part 111 are connected to form a second circuit 11b. The first circuit 11a and the second circuit 11b are connected in parallel. When the electrode part 12 is energized, the first circuit 11a and the second circuit 11b generate heat. The heat generated per unit time on the radial side A of the heating body 1 is less than the heat generated per unit time on the radial side B.

[0051] The structure of the heating circuit section 11 can be formed by hollowing out, and the heating element 1 is preferably integral.

[0052] When the heating element 1 is used in an atomizing device, the liquid guide 2 can be inserted into the heating element 1. The liquid guide 2 conducts the liquid to the heating element 1 for heating and atomization, and the airflow carries the atomized gas out through the heating element 1. When the atomizing device is an electronic cigarette, the heating element 1 heats and atomizes the e-liquid in the electronic cigarette.

[0053] The heating element 1 has its heating surface concentrated on one side, B, while the other side, A, generates little or no heat. When this heating element 1 is used in atomizing devices such as electronic cigarettes, the airflow can pass through side B, thus avoiding a large temperature difference, improving the flavor of the smoke, and preventing carbon buildup due to excessive heat. Furthermore, liquid can enter the liquid guide 2 through the gap on side A, preventing insufficient liquid supply and the resulting burnt taste caused by liquid entering from both ends and having an excessively long liquid flow path.

[0054] In some embodiments, see Figure 3-5 The electrode portion 12 is in the shape of a ring around the axis of the heating element 1; in other embodiments, the electrode portion 12 is in the shape of axial or radial protrusion.

[0055] In some implementations, see Figure 3-5 The first connecting part 111 is provided on one radial side A, and the second connecting part 112, the third connecting part 113 and the fourth connecting part 114 are provided on the other side B. The cross-sectional area of ​​the first connecting part 111 is larger than the circumferential cross-sectional area of ​​the third connecting part 113, and the circumferential dimension of the first connecting part 111 is larger than the circumferential dimension of the second connecting part 112, the third connecting part 113 and the fourth connecting part 114. Because the cross-sectional area is large and the resistance is small, the heat generated per unit time is small. Therefore, the heat generated by the first connecting part 111 per unit time is less than the heat generated by the second connecting part 112, the third connecting part 113 and the fourth connecting part 114 per unit time, so that the heat generated on one radial side A of the heating body 1 per unit time is less than the heat generated on the other radial side B per unit time.

[0056] See Figure 3-5 Preferably, from the middle to both ends of the heating body 1, the circumferential dimensions of the first connecting portion 111 are equal, the circumferential dimensions of the second connecting portion 112 are equal, the circumferential dimensions of the fourth connecting portion 114 are equal, and the circumferential dimension of the second connecting portion 112 is equal to the circumferential dimension of the fourth connecting portion 114.

[0057] See Figure 3-5Preferably, the first connecting part 111 is provided with a liquid inlet hole 1111 that runs through the inside and outside. When the heating element 1 is applied in the atomizing device, the liquid can enter the liquid guide 2 from the side of the first circuit 11a. The liquid inlet hole 1111 can improve the liquid inlet efficiency to achieve a more sufficient liquid supply.

[0058] See Figure 13-14 The dimensions of the connecting portions of the heating element 1 can also be such that, from the middle to both ends of the heating element 1, the circumferential dimension of the first connecting portion 111 increases, the circumferential dimension of the second connecting portion 112 decreases, and the circumferential dimension of the fourth connecting portion 114 decreases. The circumferential dimension changes of the first connecting portion 111, the second connecting portion 112, and the fourth connecting portion 114 can be gradual (see...). Figure 13-14 It can also be phased (see...). Figure 15 When the heating element 1 is applied in the atomizing device, liquid can enter the liquid guide 2 from the side of the first circuit 11a. Due to the principle of heat radiation, the temperature in the middle section is high, and the air inlet is also in the middle part of the heating element 1. In this embodiment, the heating element concentrates the heating area in the middle part of the heating element. In this way, the middle section has a larger heating atomization area and a larger air flow, which can achieve the effect of heat balance.

[0059] See Figure 16-17 The dimensions of the connecting portions of the heating element 1 can also be such that, from the middle to both ends of the heating element 1, the circumferential dimension of the first connecting portion 111 decreases, the circumferential dimension of the second connecting portion 112 increases, and the circumferential dimension of the fourth connecting portion 114 increases. The circumferential dimension changes of the first connecting portion 111, the second connecting portion 112, and the fourth connecting portion 114 can be gradual (see...). Figure 16-17 It can also be phased (see...). Figure 18 When heating element 1 is used in an atomizing device, a liquid feeding method can be adopted, where liquid is fed from both ends of the heating element along its axial direction towards the middle. Because the heating circuit in the middle section of the heating element in this embodiment is shorter and the circuits at both ends are longer (the atomization area is smaller in the middle and larger at both ends), it can better match the liquid supply distance, achieving a balanced effect. This avoids the possibility of insufficient liquid supply in the middle section due to the high heat of the heating element 1 and the long liquid supply distance, which could lead to wick clogging.

[0060] In some implementations, see Figure 6-8 The circumferential dimension of the second connecting part 112 is greater than that of the fourth connecting part 114. The heat generated by the second connecting part 112 per unit time is less than that generated by the fourth connecting part 114 per unit time, so that the heat generated by one radial side A of the heating body 1 per unit time is less than that generated by the other radial side B per unit time.

[0061] See Figure 6-8Preferably, the axial dimensions of the second connecting part 112 and the fourth connecting part 114 are equal; thus, the heating line of the first circuit 11a is much longer than that of the second circuit 11b, and the resistance of the first circuit 11a is much greater than that of the second circuit 11b. Since the first circuit 11a and the second circuit 11b are parallel circuits with the same voltage across them, according to I=U / R, the current in the first circuit 11a is much smaller than that in the second circuit 11b. Therefore, according to the power P=I 2 R = UI. The power of the first circuit 11a is much less than that of the second circuit 11b. Therefore, the heat of the first circuit 11a is much lower than that of the second circuit 11b.

[0062] In some implementations, see Figure 9-12 The second connecting part 112 and the fourth connecting part 114 are respectively provided on the radial sides of the heating body 1. The axial dimension of the second connecting part 112 is smaller than the axial dimension of the fourth connecting part 114. The distance between the second connecting parts 112 is greater than the distance between the fourth connecting parts 114. The heat generated by the second connecting part 112 per unit time is less than the heat generated by the fourth connecting part 114 per unit time, so that the heat generated by one radial side A of the heating body 1 per unit time is less than the heat generated by the other radial side B per unit time.

[0063] See Figure 9-12 Preferably, the circumferential dimensions of the second connecting portion 112 and the fourth connecting portion 114 are equal.

[0064] In the above Figure 6-12 In the embodiment, preferably, the circumferential dimensions of the first connecting portion 111 and the third connecting portion 113 are smaller than the circumferential dimensions of the second connecting portion 112 and the fourth connecting portion 114.

[0065] In the above technical solution, preferably, the circumferential dimensions of each second connecting portion 112 are equal, the circumferential dimensions of each fourth connecting portion 114 are equal, the circumferential dimensions of each first connecting portion 111 are equal, and the circumferential dimensions of each third connecting portion 113 are equal. The thickness of each part of the heating element 1 is equal, that is, the radial dimensions are equal.

[0066] In the above technical solution, preferably, the first connecting part 111 and the third connecting part 113 are offset in the axial direction.

[0067] In the above technical solution, preferably, the heating circuit part 11 is connected to the two electrode parts 12 through the first connecting part 111 or the third connecting part 113.

[0068] See Figure 19-21An atomizing device according to one embodiment of the present invention includes the heating element 1 described above, and further includes a housing 3 and a liquid guide 2. The liquid guide 2 passes through the heating element 1. The housing 3 is provided with a liquid channel 31, an air inlet 32, and an air outlet 33. A liquid storage chamber 34 can be disposed in or outside the housing 3 and communicates with the liquid channel 31. The liquid channel 31 and the air inlet 32 ​​respectively lead to the radial sides of the heating element 1. When the heating element is energized, the heat generated per unit time on the side of the heating element 1 connected to by the liquid channel 31 is less than the heat generated per unit time on the side of the heating element 1 connected to by the air inlet 32. Figure 19-21 In this embodiment, the liquid channel 31 leads to the upper side of the heating body 1, and the air inlet 32 ​​leads to the lower side of the heating body 1. The liquid passes through the upper side of the heating body 1 and enters the liquid guide 2. The liquid guide 2 conducts the liquid to the heating body 1 for heating and atomization. The external airflow enters the housing 3 through the air inlet 32, passes through the heating body 1, and carries the atomized gas out of the housing 3 through the air outlet 33.

[0069] The liquid in this atomizing device is supplied directly from the radial side of the tubular heating element along the radial direction, resulting in a shorter path and more ample liquid supply. The lower side has higher heating efficiency and a better match with the airflow path, avoiding the problem of high surface heat in areas where the upper airflow is less likely to pass. Heat from the lower part of heating element 1 is conducted to the upper side, preheating the e-liquid and reducing its kinematic viscosity, ensuring a more sufficient liquid supply. This further prevents problems such as dry burning due to insufficient liquid supply and the generation of harmful substances from excessively high temperatures.

[0070] See Figure 22-24 Another embodiment of the atomizing device of the present invention includes a heating element 1 as described above, a housing 3, and a liquid guide 2. The liquid guide 2 passes through the heating element 1 and extends axially out of the heating element 1 at both ends. The housing 3 is provided with a liquid channel 31, an air inlet 32, and an air outlet 33. A liquid storage chamber 34 can be disposed in or outside the housing 3 and communicates with the liquid channel 31. The liquid channel 31 leads to the two ends of the liquid guide 2 extending out of the heating element 1. The air inlet 32 ​​leads to a radial side of the heating element 1. The heat generation per unit time on the side of the heating element 1 to which the air inlet 32 ​​leads is greater than the heat generation per unit time on the other side. Figure 22-24 In this embodiment, the air inlet 32 ​​leads to the lower side of the heating body 1, and the two sides are the upper side; the liquid and the liquid guide 2 are in contact at both ends, and the liquid guide 2 conducts the liquid to the heating body 1 for heating and atomization. The external airflow enters the housing 3 through the air inlet 32, passes through the heating body 1, and carries the atomized gas out of the housing 3 through the air outlet 33.

[0071] Compared to traditional methods where the heating element is wrapped around the middle of the liquid-guiding cotton, where heat is generated circumferentially but the airflow doesn't pass directly above it, failing to carry the high-temperature atomized vapor out of the atomization chamber, resulting in poor atomization and some e-liquid flavors not being extracted. Furthermore, the ineffective heating area at the top wastes energy, leading to poor battery life. This atomization device, through its heat distribution design of the tubular heating element 1, achieves a perfect match between the heated atomization surface and the liquid-guiding fluid 2 through which the airflow passes, resulting in a balanced heat distribution. This ensures that the heat generated by the atomization components is more evenly distributed during use, even with airflow, resulting in better atomization, longer battery life, and avoiding unnecessary energy waste.

[0072] The atomizing device of the present invention can be applied to electronic cigarettes. The liquid storage tank 34 stores e-liquid, and the atomized e-liquid is heated by the heating element 1.

[0073] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications, combinations, and variations.
