Technical Field

The present application relates to the field of atomization technology, and in particular to an atomization core, an atomizer and an electronic atomization device.

Background Art

Aerosol is a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gas medium. Since aerosol can be absorbed by the human body through the respiratory system, it provides users with a new alternative absorption method. For example, electronic atomization devices that can heat liquid or solid aerosol-generating substrates to generate aerosols are used in different fields to deliver inhalable aerosols to users, replacing conventional product forms and absorption methods.

Generally, electronic atomization devices atomize aerosol-generating substrates, which are substrate materials that can generate aerosols after atomization. However, in traditional electronic atomization devices, the central area of the heating film is high in temperature, the two sides are low in temperature, and the temperature field is unevenly distributed, which makes it easy for local high-temperature carbon deposition to occur when the heating film is working normally, thus affecting the service life of the heating film and the user's taste experience.

Summary of the invention

Based on this, it is necessary to provide an atomization core, an atomizer and an electronic atomization device to address the problems of short service life of the heating film in traditional electronic atomization devices and poor taste for users.

An atomizing core includes a liquid absorbing member and a heating element, wherein the heating element is arranged on the liquid absorbing member, and the heating element includes:

A heating body, the heating body comprising a first conductive part, a second conductive part and two heating parts, each of the heating parts is connected between the first conductive part and the second conductive part along a first direction, and the two heating parts are spaced apart from each other along a second direction intersecting the first direction; and

A first guide portion, wherein the first guide portion is disposed between the two heating portions;

Wherein, at least parts of the two heating parts are protruding in directions away from each other.

In the above-mentioned atomizer core, the heating part is connected between the first conductive part and the second conductive part and is located in the middle area of the heating element. In addition, at least part of the two heating parts are protruded in a direction away from each other, so that the two heating parts are expanded outward, the heating area of the middle area of the heating element is reduced, and the heating temperature of the middle area of the heating element is reduced, and the heating temperature of the middle area and the peripheral area of the heating element is more uniform, which reduces the possibility of local high-temperature carbon deposition when the heating element is working, and improves the service life of the heating element and the user's taste experience.

Furthermore, compared with a blank setting in the interval area between two heating parts, by setting the first guide part in the interval area between two adjacent heating parts, the thickness of the aerosol generating matrix entering the interval area will become higher, thereby increasing the contact area between the aerosol generating matrix and the side wall of the heating element, improving the lateral oil supply capacity of the heating element, and enhancing the atomization effect.

In one of the embodiments, the heating portion includes an arc segment, and the two arc segments of the two heating portions are bent in directions away from each other.

In one of the embodiments, the two arc segments of the two heating parts are symmetrically arranged relative to an axis extending along the first direction.

In one embodiment of the present application, an electronic atomization device is provided, including an atomizer, which heats an atomized aerosol generating matrix when in operation to form an aerosol for a user to inhale. Generally, the electronic atomization device also includes a power supply component, a power supply component, and a power supply component. The power supply assembly is used to supply power to the atomizer.

Referring to FIG. 1 , the atomizer includes an atomizer core, and an aerosol generating matrix is stored inside the atomizer. After the aerosol generating matrix flows to the atomizer core, the atomizer core heats and atomizes the aerosol generating matrix. Specifically, the atomizer core includes a liquid absorbing member (not shown) and a heating element 100. The heating element 100 is disposed on the liquid absorbing member. The liquid absorbing member absorbs the aerosol generating matrix. The heating element 100 heats the aerosol generating matrix on the liquid absorbing member and atomizes it to form an aerosol. Optionally, the liquid absorbing member is a porous material structure, such as ceramic.

The heating element 100 includes a heating body 10, and the heating body 10 includes a first conductive portion 12, a second conductive portion 14, and two heating portions 16. Each heating portion 16 is connected between the first conductive portion 12 and the second conductive portion 14 along a first direction, and along a second direction intersecting the first direction, the two heating portions 16 are spaced apart from each other, and at least parts of the two heating portions 16 are protruded in a direction away from each other.

In this way, the heating part 16 is connected between the first conductive part 12 and the second conductive part 14, so that the heating part 16 is connected to the circuit through the first conductive part 12 and the second conductive part 14, so that the heating part 16 is powered on and generates heat. In addition, the two heating parts 16 are arranged at intervals from each other in the second direction, and at least parts of the two heating parts 16 are arranged to protrude in a direction away from each other, so that the two heating parts 16 are expanded outward, and the distribution amount of the heating parts 16 in the middle area is reduced, thereby reducing the heating temperature of the middle area of the heating element 100, and the heating temperature of the middle area and the peripheral area of the heating element 100 is more uniform, reducing the possibility of local high-temperature carbon deposition when the heating element 100 is working, and improving the service life of the heating element 100 and the user's taste experience.

According to some embodiments of the present application, the heating portion 16 includes an arc segment 161, and the two arc segments 161 of the two heating portions 16 are bent in a direction away from each other. In this way, the space between the two heating portions 16 is increased by the arc segment 161 that bends outward. On the one hand, the temperature difference between the central area and the peripheral area is reduced by increasing the hollow area of the central area, and the temperature field of the heating element 100 is uniform. On the other hand, the arc segment 161 is used to increase the contact length between the heating portion 16 and the aerosol generating matrix on the liquid absorbing member, thereby improving the atomization effect of the heating element 100.

Optionally, the two arc segments 161 of the two heating parts 16 are symmetrically arranged relative to the axis extending along the first direction, and the two arc segments 161 are symmetrically arranged so that the two heating parts 16 can evenly heat and atomize the aerosol to generate the substrate. For example, in the heating element 100 shown in FIG1 , the two heating parts 16 are symmetrically arranged up and down.

Specifically, the arc segment 161 is an arc, which is equivalent to the two arc segments 161 being two opposite parts on the same virtual circle. The two concentrically oppositely arranged arc segments 161 are symmetrical to each other, and can symmetrically and evenly heat the atomized aerosol-generating substrate. At the same time, the two oppositely arranged arc segments 161 balance the atomization temperature difference between the center and the periphery by expanding outward, thereby improving the atomization uniformity.

It can be understood that the arc segment 161 can also be set to a non-circular arc shape, for example, the arc segment 161 can be set to other shapes such as a wave shape.

According to some embodiments of the present application, the heating portion 16 further includes a straight section 163, one end of the straight section 163 and the arc section 161, and the other end of the straight section 163 is connected to the first conductive part 12 or the second conductive part 14. In this way, the arc section 161 and the first conductive part 12 or the second conductive part 14 are transitionally connected through the straight section 163, which is convenient for production and manufacturing.

According to some embodiments of the present application, the heating element 100 further includes a first guide portion 30, which is disposed between two adjacent heating portions 16. Compared with a blank arrangement in the interval area between two adjacent heating portions 16, the arrangement of the first guide portion 30 in the interval area between two adjacent heating portions 16 increases the thickness of the aerosol generating matrix entering the interval area, thereby increasing the contact area between the aerosol generating matrix and the side wall of the heating element 100, improving the lateral oil supply capacity of the heating element 100, and enhancing the atomization effect.

Among them, the lateral oil supply capacity refers to the ability to supply oil to the heating element 100 in a direction parallel to the plane where the heating element 100 is located. When the first guide portion 30 is arranged in the interval area between the two heating portions 16, the thickness of the aerosol generating matrix in the interval area becomes higher, and the contact area with the side wall of the heating element 100 in the direction parallel to the plane where the heating element 100 is located becomes larger, and the oil supply capacity is improved.

It can be understood that the area size of the first guide portion 30 can be set according to the atomization requirements and is not limited here.

Specifically in this embodiment, the first guide portion 30 is isolated and disposed between the two heating portions 16. The first guide portion 30 is not connected to the two adjacent heating portions 16, and there is a gap between the first guide portion 30 and the two heating portions 16, so that the aerosol generating substrate can flow smoothly between the heating portion 16 and the first guide portion 30, thereby improving the work uniformity and the atomization effect. It can be understood that in some other embodiments, the first guide portion 30 can also be arranged to be connected to the adjacent heating portion 16.

Referring to FIG. 2 , according to some embodiments of the present application, the heating element 100 further includes a second guide portion 50, and the second guide portion 50 is spaced and surrounds the outer periphery of the heating body 10. In this way, the second guide portion 50 is spaced and surrounds the outer periphery of the heating body 10, so as to enclose another gap between the second guide portion 50 and the heating body 10, and the aerosol generating matrix flows from the liquid absorbing member to the gap, and the aerosol generating matrix film formed when it is retained in the gap is relatively thick, which can fully supply liquid to the heating element 100 in a plane parallel to the heating element 100, thereby improving the lateral liquid supply capacity and enhancing the atomization effect.

Among them, the lateral oil supply capacity refers to the ability to supply oil to the heating element 100 in a direction parallel to the plane where the heating element 100 is located. When the second guide portion 50 is arranged at intervals outside the heating body 10, the thickness of the aerosol generating matrix on the periphery of the heating body 10 becomes higher, and the contact area between the aerosol generating matrix and the side wall of the heating element 100 in a direction parallel to the plane where the heating element 100 is located becomes larger, and the oil supply capacity is improved.

Furthermore, the second guide portion 50 is constructed as a closed annular structure, so that a closed annular gap can be formed between the second guide portion 50 and the heating body 10, so that the aerosol generating matrix can be more stably retained in the closed annular gap, and the retained aerosol generating matrix is more and thicker, and the liquid supply and atomization effects are better.

Specifically, in one embodiment, the heating element 100 includes a heating body 10, a first guide portion 30 and a second guide portion 50. The two heating portions 16 in the heating body 10 are arranged at intervals to form a hollow gap in the central area of the heating element 100, so as to reduce the possibility of high-temperature carbon deposition in the central area of the heating element 100, thereby improving the service life of the heating element 100 and the user's mouth. In addition, by providing the first guide portion 30 in the gap between two adjacent heating portions 16, the thickness of the aerosol generating matrix in the gap can be increased, thereby improving the liquid supply and atomization effects. At the same time, a second guide portion 50 can also be provided around the periphery of the heating body 10 to increase the thickness of the aerosol generating matrix around the periphery of the heating body 10, thereby further improving the liquid supply and atomization effects.

According to some embodiments of the present application, the present application further provides the above-mentioned atomizer. After the atomizer is powered on, the atomizer core is used to heat the atomized aerosol to generate a matrix.

According to some embodiments of the present application, the present application further provides an atomizer core as described above. The atomizer core comprises a liquid absorbing member and a heating element 100, wherein the heating element 100 is disposed on the liquid absorbing member and heats and atomizes the aerosol-generating matrix conducted by the liquid absorbing member when the heating element 100 generates heat.

The heating element 100 includes a heating body 10, and the heating body 10 includes a first conductive portion 12, a second conductive portion 14, and two heating portions 16. Each heating portion 16 is connected between the first conductive portion 12 and the second conductive portion 14 along a first direction, and along a second direction intersecting the first direction, the two heating portions 16 are spaced apart from each other, and at least parts of the two heating portions 16 are protruded in a direction away from each other.

In this way, the heating part 16 is connected between the first conductive part 12 and the second conductive part 14, so that the heating part 16 is connected to the circuit through the first conductive part 12 and the second conductive part 14, so that the heating part 16 is powered on and generates heat. In addition, the two heating parts 16 are arranged at intervals from each other in the second direction, and at least parts of the two heating parts 16 are arranged to protrude in a direction away from each other, so that the two heating parts 16 are expanded outward, and the distribution amount of the heating parts 16 in the middle area is reduced, thereby reducing the heating temperature of the middle area of the heating element 100, and the heating temperature of the middle area and the peripheral area of the heating element 100 is more uniform, reducing the possibility of local high-temperature carbon deposition when the heating element 100 is working, and improving the service life of the heating element 100 and the user's taste experience.

Moreover, after the two heating parts 16 are designed to be expanded outward, the distance between the two heating parts 16 becomes larger, and the aerosol generating matrix entering the pores between the two heating parts 16 is spread out. The thickness of the aerosol generating matrix is relatively low, and the contact area between the aerosol generating matrix and the side wall of the heating part 16 is relatively small, which will affect the atomization effect.

Based on this, in order to ensure the atomization effect while achieving uniform heating temperature, the heating element 100 further includes a first guide portion 30, which is disposed between two adjacent heating portions 16. Compared with a blank arrangement in the interval area between two adjacent heating portions 16, the thickness of the aerosol generating matrix entering the interval area will be increased by arranging the first guide portion 30 in the interval area between the two adjacent heating portions 16, thereby increasing the contact area between the aerosol generating matrix and the side wall of the heating element 100, improving the lateral oil supply capacity of the heating element 100, and enhancing the atomization effect.

Among them, the lateral oil supply capacity refers to the ability to supply oil to the heating element 100 in a direction parallel to the plane where the heating element 100 is located. When the first guide portion 30 is arranged in the interval area between the two heating portions 16, the thickness of the aerosol generating matrix in the interval area becomes higher, and the contact area with the side wall of the heating element 100 in the direction parallel to the plane where the heating element 100 is located becomes larger, and the oil supply capacity is improved.

The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
