Definitions

  • the present application relates to the field of atomization technology, and in particular to an atomization core, an atomizer and an electronic atomization device.
  • 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.
  • 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:
  • At least parts of the two heating parts are protruding in directions away from each other.
  • 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.
  • the first guide portion is isolated and arranged between the two heat generating portions.
  • first and second are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as “first” and “second” may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality” is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
  • a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.
  • a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature.
  • a first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the first guide portion 30 can also be arranged to be connected to the adjacent heating portion 16.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
