[0002] The current cotton core heating element adopts a parallel design of multiple hexagonal heating units, in which two adjacent hexagonal heating units share a side as the middle connecting line between the two adjacent heating units. The middle connecting line is used to press the oil-conducting cotton; and the remaining sides of the heating unit are used as the area for generating Joule heat, with a higher energy density. In general, in a heating element, the number of middle connecting lines is equal to the number of hexagonal heating units. However, due to the size of the heating area of ​​the heating element, the number of hexagonal heating units of a single heating element is limited, that is, the number of middle connecting lines of a single heating element is limited, which easily leads to insufficient cotton pressing force of the middle connecting line, making the oil-conducting cotton more likely to bulge in the middle of the hexagonal heating element, causing the heating element to deform and produce a burnt smell. When the oil-conducting cotton bulges severely and causes the heating element to deform severely, it is also easy to have problems such as loose cotton pressing and leakage. Utility Model Content

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] An embodiment of the present application provides an atomizer, which includes an atomizer core and a liquid storage part. The liquid storage part is provided with an air flow channel and a liquid storage cavity, wherein the atomizer core is at least partially disposed in the air flow channel and is in liquid communication with the liquid storage cavity.

[0030] In some specific embodiments, the atomizer further includes a power supply part connected to the liquid storage part, wherein the power supply part includes a battery, and the battery is electrically connected to the atomizer core to power the atomizer core when the atomizer core is working.

[0031] See also Figure 1-3 In some embodiments, the atomizer core includes an oil guide body and a heating body, and the heating body is arranged on the oil guide body. The heating body includes a first electrode 1, a second electrode 2, and a plurality of heating units 3 connected in series between the first electrode 1 and the second electrode 2; each heating unit 3 includes a reinforcing portion and two heating portions 31 arranged in parallel; each heating portion 31 has a first connection point 311 and a second connection point 312, the first connection point 311 is close to the first electrode 1, and the second connection point 312 is close to the second electrode 2; in the same heating unit 3, the reinforcing portion is connected to at least the first connection point 311 of one of the heating portions 31, and is connected to at least the second connection point 312 of another heating portion 31; along the direction of the first electrode 1 and the second electrode 2, between two adjacent heating units 3, the second connection point 312 of the previous heating portion 31 is the first connection point 311 of the next heating portion 31.

[0032] Exemplarily, the oil-conducting body may be oil-conducting cotton. In an embodiment of the utility model, the heating body includes two electrodes and a plurality of heating units 3 connected in series between the two electrodes, and the current will flow from one of the electrodes to the heating unit 3, and then flow out from the other electrode. When the atomizer core is working, the heating unit 3 is used to heat the atomized liquid on the oil-conducting cotton. Each heating unit 3 includes a reinforcement portion and two heating portions 31 arranged in parallel. Each heating portion 31 includes a first connection point 311 close to the first electrode 1 and a second connection point 312 close to the second electrode 2. If the current flows from the first electrode 1 to the second electrode 2, when the current passes through the heating portion 31, it will flow from the first connection point 311 of the heating portion 31 to the second connection point 312. In the same heating unit 3, the reinforcement part is connected to the first connection point 311 of at least one of the heating parts 31, and is connected to the second connection point 312 of at least another heating part 31. Since the two heating parts 31 are arranged in parallel, at least part of the reinforcement part is arranged in parallel with the two heating parts 31, so that the reinforcement part can be arranged horizontally in the area defined between the two heating parts 31 to a large extent. Therefore, when the current flows from the first electrode 1 to the second electrode 2, the current will flow to the two heating parts 31 and the reinforcement part. The heating parts 31 and the reinforcement part can both be used as areas for generating Joule heat. Compared with the hexagonal heating unit 3 of the related art, the current density of the heating element of the embodiment of the utility model is more uniform, which can effectively prevent the problem of excessive local temperature of the heating element and the generation of a burnt smell. At the same time, the reinforcement part can also be used to press the oil-conducting cotton, so as to improve the compactness and uniformity of the pressed cotton of the heating element, and can effectively prevent the oil-conducting cotton from bulging, prevent the heating element from deforming, and avoid the problems of a burnt smell and liquid leakage.

[0033] It can be understood that the direction of the current may also be the direction from the second electrode 2 to the first electrode 1 .

[0034] For further information, see Figure 1 and Figure 2 In some embodiments, the reinforcement portion further includes a first reinforcement portion 32; each heating unit 3 is provided with a first reinforcement portion 32; the shape of the first reinforcement portion 32 can be a straight line, a broken line or a curve; in the same heating unit 3, the first reinforcement portion 32 is arranged between two heating portions 31; and one end of the first reinforcement portion 32 is connected to the first connection point 311 of one of the heating portions 31, and the other end is connected to the second connection point 312 of the other heating portion 31.

[0035] Specifically, a heating unit 3 is provided with a first reinforcement part 32, and one end of the first reinforcement part 32 is connected to the first connection point 311 of one of the heating parts 31, and the other end is connected to the second connection point 312 of the other heating part 31. Since the two heating parts 31 are arranged in parallel, the first reinforcement part 32 and the two heating parts 31 are arranged in parallel. The first reinforcement part 32 and the two heating parts 31 can both be used as areas for generating Joule heat, so that the current density flowing to the heating element is more uniform, which can effectively prevent the problem of excessive local temperature of the heating element and the generation of a burnt smell. At the same time, the first reinforcement part 32 can also be used for pressing the oil-conducting cotton, so as to improve the compactness and uniformity of the pressed cotton of the heating element, effectively prevent the oil-conducting cotton from bulging, prevent the heating element from deforming, and avoid the problems of a burnt smell and liquid leakage.

[0036] For further information, see Figure 1 and Figure 2 In the same heating unit 3 , the lengths of the two heating portions 31 are equal, and the length of the first reinforcing portion 32 is greater than or equal to the length of the heating portion 31 .

[0037] Specifically, in some possible implementations, see Figure 1 The length of the first reinforcement part 32 is equal to the length of the heating part 31. Therefore, the resistance of the first reinforcement part 32 is equal to that of the heating part 31. Since the first reinforcement part 32 and the heating part 31 are arranged in parallel, the current flowing through the first reinforcement part 32 and the heating part 31 is equal, so that the Joule heat generated by the first reinforcement part 32 and the heating part 31 is the same, thereby preventing the local temperature of the heating element from being too high.

[0038] For some possible implementations, see Figure 2 , the length of the first reinforcement part 32 is greater than the length of the heating part 31, therefore, the resistance of the first reinforcement part 32 is greater than the resistance of the heating part 31, so that the Joule heat generated by the first reinforcement part 32 is less than the Joule heat generated by the heating part 31. The first reinforcement part 32 is arranged between the two heating parts 31. In practical applications, the heat conduction from the middle to the surroundings is slow. Therefore, when the Joule heat generated by the first reinforcement part 32 in the middle is less, the temperature of the first reinforcement part 32 in the middle and the heating parts 31 on both sides can be made almost the same, so that the heating body as a whole is more uniform in temperature.

[0039] It can be understood that the first reinforcement portion 32 can be set to be a straight line, a broken line or a curve according to the required length of the first reinforcement portion 32.

[0040] Further, in some embodiments, see Figure 1 and Figure 2The reinforcement portion further includes a second reinforcement portion 33, with the direction from the first electrode 1 to the second electrode 2 as the first direction, and the extension direction of the second reinforcement portion 33 is perpendicular to the first direction; each heating unit 3 is provided with two second reinforcement portions 33; in the same heating unit 3, one of the second reinforcement portions 33 is connected between the two parallel heating portions 31, and the other second reinforcement portion 33 is spaced apart from the previous second reinforcement portion 33 and connected between the two parallel heating portions 31. Specifically, the two ends of the first reinforcement portion 33 are respectively connected to the first connection points 311 of the two heating portions 31, and the two ends of the other second reinforcement portion 33 are respectively connected to the two heating portions 31, that is, one end of a second reinforcement portion 33 is connected to the first connection point 311 of a heating portion 31, and the other end is connected to the first connection point 311 of another heating portion 31, one end of another second reinforcement portion 33 is connected to the second connection point 312 of one heating portion 31, and the other end is connected to the second connection point 312 of another heating portion 31; along the first direction, between two adjacent heating units 3, the second reinforcement portion 33 of the upper heating unit 3 close to the next heating unit 3 and the second reinforcement portion 33 of the next heating unit 3 close to the upper heating unit 3 are the same second reinforcement portion 33.

[0041] Specifically, the heating element includes a plurality of heating units 3 arranged in sequence, each heating unit 3 is provided with two second reinforcing portions 33, and adjacent heating units 3 share the same second reinforcing portion 33. The heating unit 3 adjacent to the first electrode 1 includes an independent (not shared with other heating units 3) second reinforcing portion 33 and a shared second reinforcing portion 33; the heating unit 3 adjacent to the second electrode 2 includes a shared second reinforcing portion 33 and an independent second reinforcing portion 33; and the two second reinforcing portions 33 of the remaining heating units 3 are respectively shared with the heating units 3 adjacent to the two sides.

[0042] In the same heating unit 3, one end of one second reinforcing portion 33 is connected to the first connection point 311 of one heating portion 31 and the other end is connected to the first connection point 311 of the other heating portion 31; one end of the other second reinforcing portion 33 is connected to the second connection point 312 of one heating portion 31 and the other end is connected to the second connection point 312 of the other heating portion 31. Both second reinforcing portions 33 are connected to the equipotential points of the two heating portions, so that the current does not pass through the second reinforcing portion 33. By arranging the second reinforcing portion 33 between the two heating portions 31, the compactness and uniformity of the heating and pressing cotton can be further improved.

[0043] For some possible implementations, see Figure 1, the first reinforcement part 32 is linear, and the linear first reinforcement part 32 is in an angle relationship with the two second reinforcement parts 33. The first reinforcement part 32 is arranged in the space enclosed by the two heating parts 31 and the two second reinforcement parts 33. By changing the size of the space, that is, changing the distance between the two heating parts 31, the distance between the two second reinforcement parts 33, etc., the length of the first reinforcement part 32 can be changed, and then the first reinforcement part 32 can be made equal to or greater than the length of the heating part 31, and the temperature distribution of the heating element can be adjusted.

[0044] For some possible implementations, see Figure 2 The first reinforcement part 32 is in a broken line shape, and the first reinforcement part 32 is arranged in the space enclosed by the two heating parts 31 and the two second reinforcement parts 33. When the size of the space is determined, by changing the bending direction and bending amplitude of the first reinforcement part 32, the length of the first reinforcement part 32 can be changed, and then the first reinforcement part 32 can be equal to or greater than the length of the heating part 31, and the temperature distribution of the heating element can be adjusted. In addition, by changing the bending direction and bending amplitude of the first reinforcement part 32, the compactness and uniformity of the oil-conducting cotton pressed by the first reinforcement part 32 can also be changed.

[0045] In some possible implementations, the first reinforcement part 32 is curved, and the first reinforcement part 32 is disposed in a space enclosed by two heating parts 31 and two second reinforcement parts 33. When the size of the space is determined, the length of the first reinforcement part 32 can be changed by changing the bending degree of the first reinforcement part 32, so that the first reinforcement part 32 can be equal to or greater than the length of the heating part 31, and the temperature distribution of the heating element can be adjusted. In addition, by changing the bending direction and bending amplitude of the first reinforcement part 32, the compactness and uniformity of the oil-conducting cotton pressed by the first reinforcement part 32 can also be changed.

[0046] For further information, see Figure 3 In some embodiments, the reinforcement portion further includes a first reinforcement portion 32; each heating unit 3 is provided with two first reinforcement portions 32; in the same heating unit 3, the two first reinforcement portions 32 are arranged in parallel between the two heating portions 31; one end of one of the first reinforcement portions 32 is connected to the first connection point 311 of one of the heating portions 31, and the other end is connected to the second connection point 312 of the same heating portion 31; one end of the other first reinforcement portion 32 is connected to the first connection point 311 of the other heating portion 31, and the other end is connected to the second connection point 312 of the same heating portion 31.

[0047] Specifically, a heating unit 3 is provided with two first reinforcement parts 32, and the two ends of one of the first reinforcement parts 32 are connected to the two connection points of one of the heating parts 31, and the two ends of the other first reinforcement part 32 are connected to the two connection points of the other heating part 31. Since the two heating parts 31 are arranged in parallel, the two first reinforcement parts 32 and the two heating parts 31 are all arranged in parallel. Both the two heating parts 31 and the two first reinforcement parts 32 can be used as areas to generate Joule heat, so that the current density flowing to the heating element is more uniform, which can effectively prevent the problem of excessive local temperature of the heating element and the generation of a burnt smell. At the same time, the two first reinforcement parts 32 can also be used to press the oil-conducting cotton, so as to improve the compactness and uniformity of the pressed cotton of the heating element, which can effectively prevent the oil-conducting cotton from bulging, prevent the heating element from deforming, and avoid the problems of a burnt smell and liquid leakage.

[0048] Further, in the same heating unit 3, the lengths of the two heating parts 31 are equal; the lengths of the two first reinforcement parts 32 are both equal to the length of the heating part 31; or, the lengths of the two first reinforcement parts 32 are both greater than the length of the heating part 31; or, the length of one of the first reinforcement parts 32 is greater than the length of the heating part 31, and the length of the other first reinforcement part 32 is equal to the length of the heating part 31.

[0049] Specifically, in some possible implementations, see Figure 3 The lengths of the two first reinforcements 32 are equal to the length of the heating portion 31, therefore, the resistances of the two first reinforcements 32 and the two heating portions 31 are equal, and because the two first reinforcements 32 and the two heating portions 31 are arranged in parallel, the currents flowing through the two first reinforcements 32 and the two heating portions 31 are equal, and the Joule heat generated by the two first reinforcements 32 and the two heating portions 31 is the same, thereby preventing the local temperature of the heating element from being too high.

[0050] In some implementations, the lengths of the two first reinforcements 32 are greater than the length of the heating portion 31, and therefore, the resistances of the two first reinforcements 32 are greater than the resistance of the heating portion 31, so that the Joule heat generated by the two first reinforcements 32 is less than the Joule heat generated by the heating portion 31. The two first reinforcements 32 are both arranged between the two heating portions 31. In practical applications, the heat conduction from the middle to the surroundings is slower. Therefore, when the Joule heat generated by the middle first reinforcement 32 is less, the temperature of the middle first reinforcement 32 and the heating portions 31 on both sides can be made almost the same, so that the heating element as a whole is more evenly heated.

[0051] In some feasible embodiments, the length of one of the first reinforcement parts 32 can be greater than that of the heat generating part 31, and the length of the other first reinforcement part 32 can be equal to that of the heat generating part 31, so that the Joule heat generated by one of the first reinforcement parts 32 is less than that generated by the heat generating part 31, and the Joule heat generated by the other first reinforcement part 32 is the same as that generated by the heat generating part 31, so that the temperature distribution of the heat generating body can be flexibly adjusted.

[0052] Further, in some embodiments, see Figure 3 The reinforcement part also includes a second reinforcement part 33, with the direction from the first electrode 1 to the second electrode 2 as the first direction, and the extension direction of the second reinforcement part 33 is perpendicular to the first direction; each heating unit 3 is provided with two second reinforcement parts 33; in the same heating unit 3, one of the second reinforcement parts 33 is connected between the two first reinforcement parts 32 in parallel, and the other second reinforcement part 33 is spaced apart from the previous second reinforcement part 33 and connected between the two first reinforcement parts 32 in parallel.

[0053] Specifically, the heating element includes a plurality of heating units 3 arranged in parallel in sequence, each heating unit 3 is provided with two second reinforcement parts 33, the current direction is parallel to the first direction, and the extension direction of the second reinforcement part 33 is perpendicular to the first direction. In the same heating unit 3, the two heating parts 31 are arranged at intervals along the extension direction of the second reinforcement part 33, the two first reinforcement parts 32 are arranged at intervals along the extension direction of the second reinforcement part 33, and the two first reinforcement parts 32 are arranged between the two heating parts 31, and the two second reinforcement parts 33 are arranged between the two first reinforcement parts 32. The two second reinforcement parts 33 are both connected to the equipotential point between the two heating parts, so that the current does not pass through the second reinforcement part 33. By arranging the second reinforcement part 33 between the two heating parts 31, the compactness and uniformity of the heating pressed cotton can be further improved.

[0054] Furthermore, the shape of the first reinforcement portion 32 may be a broken line or a curved line.

[0055] In some embodiments, in some implementations, see Figure 3 , the two first reinforcement parts 32 are both in the shape of a broken line, and the two first reinforcement parts 32 have two endpoints, and the two first reinforcement parts 32 can also have two inflection points. And each reinforcement part has a connecting line connected between the two inflection points, and the connecting line is parallel to the connecting direction of the first electrode 1 and the second electrode 2. The two second reinforcement parts 33 are arranged in parallel and spaced apart, and the two second reinforcement parts 33 and the two connecting lines enclose a quadrilateral structure located in the middle of the heating unit 3. The two endpoints of the first reinforcement part 32 extend in a direction away from the second reinforcement part 33 and are connected to the two connection points of the heating part 31.

[0056] It is understandable that the embodiment of the utility model does not limit the bending direction and bending degree of the first reinforcing portion 32. By changing the bending direction and bending degree of the first reinforcing portion 32, the length of the first reinforcing portion 32 can be changed, so that the first reinforcing portion 32 is equal to or greater than the length of the heating portion 31, and the temperature distribution of the heating element can be adjusted. In addition, by changing the bending direction and bending amplitude of the first reinforcing portion 32, the compactness and uniformity of the oil-conducting cotton pressed by the first reinforcing portion 32 can also be changed.

[0057] In some implementations, the two first reinforcement parts 32 may also be curved. By changing the bending direction and bending amplitude of the first reinforcement part 32, the length of the first reinforcement part 32 may be changed, so that the first reinforcement part 32 is equal to or greater than the length of the heating part 31, and the temperature distribution of the heating element may be adjusted. In addition, by changing the bending direction and bending amplitude of the first reinforcement part 32, the compactness and uniformity of the oil-conducting cotton pressed by the first reinforcement part 32 may also be changed.

[0058] It can be understood that, in the same heating unit 3, the shapes of the two first reinforcement parts 32 can be the same or different.

[0059] For further information, see Figure 3 In some embodiments, in the same heating unit 3, two first reinforcement parts 32 are arranged in parallel and symmetrically.

[0060] Furthermore, the shape of the heating part 31 is a straight line, a broken line or a curved line; in the same heating unit 3, the shapes of the two heating parts 31 can be the same or different. By changing the shape of the heating part 31 and the shape of the first reinforcement part 32, the length of the heating part 31 and the first reinforcement part 32 can be adjusted, the current density flowing through the heating element can be changed, and thus the temperature distribution of the heating element can be adjusted. At the same time, the compactness and uniformity of the oil-conducting cotton pressed by the first reinforcement part 32 can also be adjusted.

[0061] For further information, see Figure 1-3 In the same heating unit 3, the two heating parts 31 are symmetrically arranged. Specifically, in the same heating unit 3, the two heating parts 31 are arranged in parallel. In some embodiments, the shape of the heating part 31 is a broken line, and the two heating parts 31 are symmetrically arranged.

[0062] For some possible implementations, see Figure 1 and Figure 2The shape of the heating part 31 is <-shaped, and the two heating parts 31 and the two second reinforcement parts 33 enclose a hexagon. Each heating unit 3 is provided with a first reinforcement part 32, and the first reinforcement part 32 is arranged in the middle of the hexagon, and the first reinforcement part 32 is arranged in parallel with the two heating parts 31. The first reinforcement part 32 and the two heating parts 31 can both be used as areas for generating Joule heat, so that the current density of the heating element is more uniform, which can effectively prevent the problem of excessive local temperature of the heating element and the generation of a burnt smell. At the same time, the first reinforcement part 32 located in the middle of the hexagon can also be used for pressing the oil-conducting cotton, which can further improve the compactness and uniformity of the pressed cotton of the heating element, and can effectively prevent the oil-conducting cotton from bulging, prevent the heating element from deformation, and avoid the problems of a burnt smell and liquid leakage.

[0063] For some possible implementations, see Figure 3 The shape of the heating part 31 is <-shaped, and each heating unit 3 is provided with two first reinforcement parts 32. One of the heating parts 31 and one of the first reinforcement parts 32 enclose a pentagon, and the other heating part 31 and the other first reinforcement part 32 also enclose a pentagon. The two first reinforcement parts 32 and the two heating parts 31 can both be used as areas for generating Joule heat, so that the current density of the heating element is more uniform. At the same time, the two first reinforcement parts 32 located between the two heating parts 31 can also be used to press the oil-conducting cotton, which can further improve the compactness and uniformity of the cotton pressed by the heating element.

[0064] Furthermore, the heating element further includes support areas arranged on both sides of the heating unit 3, the atomizer core further includes a support member, the oil-conducting cotton is arranged on the heating unit 3, and the support member is pressed on the support area and presses the oil-conducting cotton.
