The tobacco liquid contains tobacco components such as nicotine, and forms air flow easy for human body to inhale after being heated and atomized. The electromagnetic atomizer heats the smoke liquid of the atomized electronic cigarette by utilizing the electromagnetic induction principle and delivers the airflow formed by atomization to the mouth of a user. In the working process of the electromagnetic atomizer, the induction coil can generate an alternating magnetic field after alternating current is introduced, so that the surface of a conductor (heating element) in the magnetic field forms induced eddy current, the conductor rapidly heats by utilizing the eddy current and the internal resistance of the conductor, and the atomization of smoke liquid is realized. It should be noted that the application scenario type of the embodiment of the present utility model does not limit the structure of the atomizing assembly of the present utility model.

As shown in fig. 1, the electromagnetic atomizer comprises an atomizing assembly 1, a cartridge 2, an inductance coil 3, a circuit board 4 and a power supply 5, wherein the atomizing assembly 1 is arranged inside the electromagnetic atomizer. Fig. 2 is an enlarged partial schematic view of fig. 1 in the vicinity of the atomizing assembly, which includes a base 11 and a heat generating body 12, as shown in fig. 2. In the case where the atomizing assembly is provided in the electromagnetic atomizer, the atomizing assembly may be provided in the tube 10, the tube 10 is hollow, and the base 11 and the heating element 12 are provided in the tube 10. As shown in fig. 1 and 2, the tube body 10 has an opening at least at one end in the longitudinal direction, so that the air flow formed after atomization of the smoke liquid can be discharged from the tube body 10. Of course, it will be appreciated by those skilled in the art that the atomizing assembly could be provided in other shapes and/or configurations of the tube body 10 without affecting the scope of the atomizing assembly.
In some embodiments, as shown in fig. 2, the substrate 11 absorbs the liquid to be atomized. It should be noted that, the substrate 11 may be made of a porous solid material, and the pores formed by connecting the plurality of micropores may suck the liquid by capillary action, so that the liquid to be atomized is temporarily stored in the substrate 11. The material of the substrate 11 is not limited in the embodiment of the present utility model, and may be, for example, silica gel or ceramic. In the placement position shown in fig. 2, the tube body 10 has a cavity therein extending in the up-down direction of fig. 2, and the length direction of the base 11 coincides with the extending direction of the cavity inside the tube body 10, thereby contributing to space saving.
As shown in fig. 2 and 3, the heat-generating body 12 has two opposite surfaces, a first surface 121 and a second surface 122, respectively. Where the first surface 121 is disposed adjacent to the substrate 11, it is understood that all portions of the first surface 121 are adjacent to the substrate 11, and not only two ends are adjacent to the substrate, for example, the substrate 11 is provided with a groove, and the heating element is disposed in the groove, and then the surface of the heating element 12 near the bottom surface of the groove is the first surface 121. The first surface 121 is located on the back of the heat-generating body 12 at the view angle of fig. 3, so that fig. 3 illustrates the position of the first surface 121 with a broken line. It will be appreciated that the first surface 121 of the heating element 12 may be adjacent to the substrate in a variety of forms, for example, the first surface may be in direct contact with the substrate 11, or the first surface may not be in direct contact with the substrate 11 but may be in close proximity to the substrate 11, thereby allowing space for the gas flow to be ejected after the gas flow is atomized, and that in the case where there is a space between the first surface 121 and the substrate 11, no other physical component is provided in the space.
Fig. 4 is a simplified schematic diagram of the positional relationship among the base 11, the heating element 12, and the tube 10, and the dimensions of the respective components are not shown in fig. 4 in accordance with their actual dimensional ratios in order to more clearly show the positions of the respective surfaces. As shown in fig. 2 and fig. 4, the heating element 12 has a second surface 122, the second surface 122 is opposite to the first surface 121, and the opposite can be understood that the directions of the external normals of the first surface 121 and the second surface 122 are on the same straight line and opposite, for example, the substrate 11 is provided with a groove, and the heating element is disposed in the groove, so that the surface of the heating element 12 far from the bottom surface of the groove is the second surface 122. In some embodiments, first surface 121 and second surface 122 may both be considered approximately planar, such that the two planes are parallel. As shown in fig. 3, the heat generating element 12 is provided with a plurality of through holes 123 penetrating from the first surface 121 to the second surface 122, and the penetrating through holes 123 communicate the first surface 121 and the second surface 122 of the heat generating element 12. It can be understood that the heat generated by the heating element 12 can atomize the smoke liquid approaching to the heating element 12 to form an air flow, the first surface 121 of the heating element 12 is adjacent to the substrate 11, and the through hole 123 is formed in the heating element 12, so that the contact area between the smoke liquid adsorbed on the substrate and the heating element not only comprises the area of the first surface 121 but also comprises the area of the wall surface of the through hole 123, thereby increasing the contact area between the smoke liquid and the heating element relative to the scheme that the heating element 12 is not provided with the through hole, further increasing the area where atomization occurs, and being beneficial to improving the atomization efficiency. In addition, the atomized air flow can be orderly discharged from the through hole 123, so that the through hole 123 can be used as a channel for discharging the air flow of the atomizing assembly, which is beneficial to improving the stability of the air flow.
The shape of the through hole 123 is not limited in the embodiment of the present utility model, and for example, the through hole may be a circular hole, a square hole, a polygonal hole or other shaped holes, so as to be capable of adapting to the requirements of different atomization speeds on the basis of saving cost. The material of the heating element 12 is not limited to the material of the heating element 12, and any conductor may be used, for example, the material of the heating element 12 may be metal, or an alloy such as 430 stainless steel or 410 stainless steel, which is beneficial to adapting to different electromagnetic induction eddy current heating conditions and atomization environments.
The embodiment of the utility model provides an atomization assembly and an electromagnetic atomizer. The atomization assembly comprises a substrate and a heating body, wherein the substrate absorbs liquid to be atomized, a first surface of the heating body is arranged adjacent to the substrate, and a second surface of the heating body is arranged opposite to the first surface; wherein, the heat-generating body is offered and is run through to a plurality of through-holes of second surface from first surface. According to the embodiment of the utility model, the through holes are formed in the heating body, so that the contact area between the heating body and the liquid to be atomized is increased, and the heating body can heat and atomize more liquid at the same time, thereby being beneficial to improving the atomization efficiency; and the through holes can guide the airflow formed by atomization to be sprayed out of the holes, so that the stability of the airflow flowing direction is improved, and the atomization quality is improved.
In some embodiments, as shown in fig. 3 and 4, a groove 111 open at one end is opened on a side of the base 11 facing the heating element 12. The one-end opening means that the recess 111 is opened only at one end near the heating element 12, so that the air flow formed by atomization is guided to be discharged from the opened one end. The heating element 12 is at least partially located in the groove 111, and the other part may be located outside the groove 111, or the heating element 12 may be entirely located in the groove 111. For example, as shown in fig. 3, the heat-generating body 12 is fixed in the groove 111 by the engaging piece 124 surrounding the first surface 121 and the second surface 122 being engaged in the engaging groove 115 adjacent to the groove 111, to fixedly connect the heat-generating body 12 and the base 11.
Compared with the situation that the heating element is adjacent to only one surface of the substrate, the heating element provided by the embodiment of the utility model is adjacent to a plurality of wall surfaces surrounding the groove, so that the contact area between the heating element and the substrate can be increased, and the heating atomization efficiency is improved; and the grooves are also beneficial to storing the tobacco liquid oozing out of the matrix in the grooves, so that sufficient tobacco liquid is provided for atomization without waiting for the time of leading in the tobacco liquid, and the atomization efficiency is improved.
In some embodiments, as shown in fig. 3, the grooves 111 are open along the length of the substrate 11, the length of the substrate 11 representing the greatest dimension thereof. The heat-generating body 12 is disposed in the recess 111 so that the longitudinal direction of the heat-generating body 12 may also be along the longitudinal direction of the base 11 in order to increase the contact area of the heat-generating body 12 with the base 11. As shown in fig. 3, the base 11 has a third surface 113 surrounding the recess 111. Wherein, the base 11 is provided with a groove 111 having one end opened at a side facing the heating element 12, and the third surface 113 is a surface of the base 11 near the side of the heating element 12, so that the third surface 113 surrounds an opening of the groove 111.
As shown in fig. 3, the bottom wall 112 of the recess 111 is disposed opposite the opening of the recess 111. Wherein, the base 11 is provided with a groove 111 with one open end, and the bottom wall 112 is far away from the open end of the groove 111. As shown in fig. 4, the second surface 122 is adjacent to the bottom wall 112 of the recess 111 relative to the third surface 113 such that the third surface 113 is at a distance L from the bottom wall 112 1 Greater than or equal to the distance L from the second surface 122 to the bottom wall 112 2 It will be appreciated that the higher temperature gas stream formed by atomization will tend to condense into droplets due to temperature differences when it encounters a lower temperature object and will adhere to the lower temperature object, and the higher temperature gas stream may condense when it exits the heater, for example, the inner wall 101 of the tube. In some embodiments, as shown in FIG. 4, the inner wall 101 of the tube 10 is disposed opposite the second surface 122 of the heat-generating body, and the temperature of the inner wall 101 is relatively low compared to the heat-generating body 12, so that the gas flow with a relatively high temperature is easily adsorbed on the inner wall 101 and condensed into liquid after encountering the inner wall 101Drops, which may lead to reduced atomization efficiency; in the embodiment of the utility model, the distance from the heating element 12 to the inner wall 101 is increased by arranging the second surface 122 close to the bottom wall 112 of the groove 111 relative to the third surface 113, i.e. the condition that the third surface protrudes relative to the second surface, so that the atomized gas generated at the position of the heating element 12 has a longer distance to reach the inner wall 101, and in the process, the atomized gas has more sufficient contact and heat exchange with other gases along the path, so that when reaching the inner wall 101, the temperature difference between the atomized gas and the inner wall 101 can be correspondingly reduced, and droplets are relatively difficult to condense and form, thereby being beneficial to improving the atomization efficiency and the utilization rate of smoke liquid. Of course, it will be understood by those skilled in the art that other positional relationships between the tube and the heat generating body are possible, and that the atomizing air flow may be condensed by contacting other objects, and the above features merely provide one possible embodiment, and the structure of the tube and the positional relationship between the tube and the heat generating body do not affect the protection range of the atomizing assembly.
In some embodiments, as shown in FIG. 3, the first surface 121 of the heat-generating body 12 is attached to the bottom wall 112 of the recess 111, thereby shortening the distance of the heat-generating body 12 from the substrate 11. The distance between the heating element and the matrix is closer, and heat in the heating element is absorbed by liquid to be atomized in the matrix more easily, so that the heating efficiency is improved, and the atomizing efficiency is improved.
In some embodiments, as shown in fig. 4, the distance L between the second surface 122 and the third surface 113 3 Less than or equal to 2mm. It will be appreciated that the distance L of the third surface 113 from the bottom wall 112 1 Greater than the distance L from the second surface 122 to the bottom wall 112 2 So that the heating element 12 is positioned in the groove 111, the distance L from the third surface 113 to the bottom wall 112 1 Distance L from second surface 122 to bottom wall 112 2 The difference between the second surface 122 and the third surface 113 is the distance L 3 And L is 3 Less than or equal to 2mm but L 3 Greater than or equal to 0 (because L) 1 Greater than or equal to L 2 ). For example, as shown in FIG. 5, L 3 May be 0.5mm so that the second surface 122 is farther from the inner wall 101 than the third surface 113, resulting in an atomized shapeThe resulting air flow is less likely to contact components other than the atomizing assembly, such as the inner wall of the tube, and condensation occurs. It will be appreciated that while increasing the distance between the second surface and the third surface may reduce the likelihood of condensation of the atomized air stream on components other than the atomizing assembly, if L 3 Too large means that the third surface 113 of the base 11 is far from the heat generating body 12, and accordingly, there is a possibility that the temperature of the third surface 113 will be greatly different from the temperature of the heat generating body 12, and thus, condensation of the atomized air flow may occur at the third surface 113.
The embodiment of the utility model is realized by arranging L 3 The distance from the heating element to the part outside the atomizing assembly is increased by less than or equal to 2mm and more than or equal to 0, and the heating element is not far away from the third surface of the base body, so that atomized air flow is not easy to contact the part outside the atomizing assembly or the third surface of the base body to be condensed, and the atomization efficiency is improved.
In some embodiments, as shown in fig. 3, the bottom wall 112 is provided with a plurality of projections 114, the projections 114 protruding from the bottom wall 112 of the recess 111 toward the opening direction. Wherein each of the protrusions 114 is inserted into a corresponding one of the through holes 123. The protruding members 114 serve as a part of the base 11, smoke liquid to be atomized is sucked in, and each protruding member 114 is inserted into the corresponding through hole 123, so that the smoke liquid in the protruding member 114 can be atomized by the wall surface of the through hole 123, the contact area between the smoke liquid and the heating body 12 is increased, and the atomization efficiency is improved. It will be appreciated that the heating element 12 need only be in close proximity to the substrate 11 and need not be in full contact with the substrate 11 to heat the smoke liquid in the substrate 11. As shown in fig. 3, the protrusion 114 has a gap with the wall surface of the through hole 123, so that the air flow formed by atomization can be rapidly discharged from the gap without being retained and affecting the atomization of the remaining smoke liquid, which is advantageous for improving the atomization speed.
In some embodiments, as shown in fig. 4 and 6, the height L of the boss 114 4 Less than or equal to the distance L between the bottom wall 112 and the third surface 113 5 . Wherein the distance L between the bottom wall 112 and the third surface 113 5 Is larger than the heating element 12 from the firstThe distance from the surface 121 to the second surface 122 may be equal to the distance from the first surface 121 to the second surface 122 of the heat generating body 12, so that the protrusion 114 just passes from the first surface 121 of the heat generating body 12 to the second surface 122 of the heat generating body 12 along the X direction, which is beneficial to saving materials and reducing cost on the basis that the protrusion 114 is fully contacted with the wall surface of the through hole 123.
The shape of the protruding member 114 is not limited, for example, the shape of the protruding member 114 may be the same as the corresponding through hole 123, and when the through hole 123 is a circular hole, a square hole, a polygonal hole or other special-shaped holes, the protruding member 114 may be a cylinder, a quadrangular prism or other corresponding shapes, which is beneficial for the tobacco liquid in the protruding member 114 to be sufficiently atomized by the heating element 12, and further improves the atomization amount.
In some embodiments, as shown in FIG. 3, the length L of the heating element 12 in the longitudinal direction 6 Thickness L in thickness direction with heating element 12 7 The ratio is 10 or more, and the thickness direction is the direction in which the through hole 123 penetrates the heating element 12. Wherein the through hole 123 penetrates from the first surface 121 to the second surface 122 of the heating element 12, and the thickness L of the heating element 12 7 Representing the distance from the first surface 121 to the second surface 122. The longitudinal direction indicates the direction in which the heating element 12 extends, and the length L of the heating element 12 6 And thickness L 7 Ratio L of 6 /L 7 10 or more so that the appearance of the heat-generating body 12 assumes a lamellar structure. On one hand, the space is saved, the material cost is reduced, and on the other hand, the volume of the heating body 12 is reduced, so that the temperature rising speed of the heating body 12 is increased.
According to the embodiment of the utility model, the heating body 12 is arranged in the shape of the sheet, so that the heating time of the heating body 12 is reduced, the feedback speed of a user instruction is accelerated, the cost is saved, the atomization efficiency is improved, and the user experience is improved.
In some embodiments, the heating element 12 is integrally formed with the substrate 11, or the heating element 12 is an electromagnetic induction film printed on the surface of the substrate 11. The heating element 12 may be made of metal or alloy which can be heated by electromagnetic induction eddy current, and the heating element 12 and the substrate 11 may be molded without multiple processing. The heating element 12 may be a thin film which can be heated by electromagnetic induction eddy current, and may be printed on the surface of the substrate 11 during processing. The area of the electromagnetic induction film is smaller than the area of the surface of one side of the base 11, so that the electromagnetic induction film can be attached to the base 11. Through holes can be formed in the electromagnetic induction film as well, so that the contact area with smoke liquid is increased. According to the embodiment of the utility model, the heating body 12 and the base body 11 are integrally formed or the heating body 12 is an electromagnetic induction film, so that the material cost and the processing cost are saved, the heating speed is improved, and the atomization is accelerated.

The tube body 10 has a hollow cavity therein, and the atomizing assembly 1 can be placed in the cavity instead of being directly exposed to the outer surface of the atomizer, so that the atomizing assembly 1 is not easily polluted or damaged. An atomizing chamber 102 is formed between the second surface 122 of the heat-generating body 12 and the tube body 10 to accommodate an air stream, such as an aerosol, atomized by the heat-generating body 12.
