[0034] Referring to Fig. 1, Fig. 2 and Fig. 3, an atomizer 10 provided in one embodiment of the present application includes a base 100, a heating element 200, a liquid guide 400 and a cover plate 300. The heating element 200 is stacked on the base 100, the liquid guide 400 is stacked on the surface of the heating element 200 away from the base 100, and the cover plate 300 is connected to the base 100 and stacked on the surface of the liquid guide 400 away from the heating element 200. In view of the fact that the cover plate 300 is connected to the base 100 and the cover plate 300 is spaced apart from the base 100, the heating element 200 and the liquid guide 400 are sandwiched between the cover plate 300 and the base 100.

[0035] Referring to FIG. 1 , FIG. 2 and FIG. 3 , in some embodiments, the base 100 adopts a layered arrangement mode, that is, the base 100 may include two layers of different materials, which may be respectively recorded as a first base layer 101 and a second base layer 102, and the second base layer 102 is stacked on the first base layer 101. The hardness of the first base layer 101 may be higher than the hardness of the second base layer 102, so that the first base layer 101 and the entire base 100 have reasonable structural strength. The first base layer 101 may be made of metal or alloy material, for example, the first base layer 101 may be made of stainless steel material, and the second base layer 102 may be made of silicone material, so that the second base layer 102 has good flexibility. The heating element 200 is stacked on the second base layer 102. The thickness of the second base layer 102 is small, so that the thickness of the second base layer 102 can be much smaller than the thickness of the first base layer 101, so that the thickness of the entire base 100 can be reasonably reduced.

[0036] Referring to Fig. 1, Fig. 2 and Fig. 3, in some embodiments, the base 100 includes a substrate 110 and a stopper 120, the substrate 110 may be roughly in the shape of a cuboid, the heating element 200 is stacked on the substrate 110, the substrate 110 has a surface disposed toward the heating element 200 in the thickness direction, the surface is connected to the heating element 200, the stopper 120 is protrudingly disposed on the surface along the thickness direction of the substrate 110, and the number of the stopper 120 is multiple, so that the multiple stoppers 120 are located on the same side of the thickness direction of the substrate 110. The multiple stoppers 120 are arranged at intervals along the circumference of the substrate 110. The stopper 120 and the substrate 110 together enclose a housing space, and the heating element 200 and the liquid guide 400 are accommodated in the housing space. The stopper 120 may be provided with a matching portion, which is used to form a clamping match with the cover plate 300, so as to realize a detachable connection relationship between the cover plate 300 and the stopper 120. For example, the matching portion may be a clamping hole 121, which is used to cooperate with the cover plate 300, so as to form a detachable connection relationship between the cover plate 300 and the base 100. The clamping hole 121 maintains a certain distance from the substrate 110. For example, the stopper 120 may be a telescopic structure. When the stopper 120 is extended and retracted, the distance between the clamping hole 121 and the substrate 110 is adjustable, and the distance between the cover plate 300 and the substrate 110 can be adjusted, thereby adjusting the clamping force of the cover plate 300 on the liquid guide member 400 and the heating member 200. Obviously, the adhesion force between the heat conductor and the heating member 200 can also be adjusted. In other embodiments, the mating portion may be a convex strip, which is inserted into the hole structure of the cover plate 300, and the detachable connection relationship between the cover plate 300 and the stopper 120 can also be achieved.

[0037] Referring to FIG. 1 , FIG. 2 and FIG. 3 , in some embodiments, an air guide hole 111 is provided on the substrate 110, and the air guide hole 111 runs through the entire substrate 110 along the thickness direction of the substrate 110, so the air guide hole 111 is a through hole. The base 100 also includes a positioning column 130, and the positioning column 130 is protrudingly arranged on the substrate 110. The substrate 110 has a surface arranged toward the heating element 200, and the positioning column 130 is protrudingly arranged on the surface along the thickness direction of the substrate 110. The heating element 200 is provided with a positioning hole 250. When the heating element 200 is superimposed on the substrate 110, the positioning column 130 cooperates with the positioning hole 250, so that the heating element 200 can play a good limiting role, thereby improving the installation efficiency and installation accuracy of the heating element 200.

[0038] Referring to FIG. 1 , FIG. 2 and FIG. 3 , in some embodiments, the heating element 200 is a planar structure, and the heating element 200 includes a heating portion 210, a supporting portion 220 and a pin portion 230. There is one heating portion 210, two supporting portions 220, and two pin portions 230, wherein one supporting portion 220 is connected between one pin portion 230 and one end of the heating portion 210, and another supporting portion 220 is connected between another pin portion 230 and the other end of the heating portion 210. A plurality of mesh holes 211 are provided on the heating portion 210, and the shape of the mesh holes 211 can be circular, rhombus or regular polygon, etc. The heating portion 210 corresponds to the air guide hole 111, so that the heating portion 210 is at least partially located within the coverage range of the air guide hole 111, which can also be understood as the orthographic projection of the air guide hole 111 along the thickness direction of the substrate 110 can cover at least part of the heating portion 210. The support portion 220 may not be provided with the mesh 211. The support portion 220 is stacked on the substrate 110. The support portion 220 is at least partially located outside the coverage of the air guide hole 111. It can also be understood that the support portion 220 is at least partially located outside the coverage of the orthographic projection of the air guide hole 111 along the thickness direction of the substrate 110. The pin portion 230 is at least partially located outside the base 100. The pin portion 230 is used to be electrically connected to the power supply element, that is, the power supply element supplies power to the entire heating element 200 through the pin.

[0039] Referring to FIG. 1 , FIG. 2 and FIG. 3 , in some embodiments, a spacing gap 240 is formed between part of the pin portion 230 and the support portion 220 . By providing the spacing gap 240 , the pin portion 230 can be bent relative to the support portion 220 along the spacing gap 240 , so that it is convenient to abut against the ejector pin of the power supply element during assembly. The pin portion 230 can be located on the same side or on the opposite side of the support portion 220 . Referring to FIG. 3 , for example, the pin portion 230 can be located on opposite sides of the length direction of the heating portion 210 , so that the pin portion 230 extends from opposite sides of the length direction of the substrate 110 , and finally the pin portion 230 is located on the opposite side of the support portion 220 . Referring to FIG. 5 , for another example, the pin portion 230 can be located on the same side of the width direction of the heating portion 210 , so that the pin portion 230 extends from the same side of the width direction of the substrate 110 , and finally the pin portion 230 is located on the same side of the support portion 220 . In this way, the heating element 200 can adapt to different installation situations, ensuring that a reliable electrical connection is formed between the heating element 200 and the power supply element.

[0040] In some embodiments, the liquid guide 400 can conduct and buffer the atomized matrix of the liquid. Since the liquid guide 400 is stacked on the heating element 200, when the heating element 200 generates heat, the atomized matrix buffered on the liquid guide 400 can absorb the heat and atomize to form an aerosol, which can be inhaled by the user. The aerosol will overflow from the air guide hole 111 of the base 100.

[0041] Referring to FIG. 2, FIG. 3 and FIG. 4, in some embodiments, the cover plate 300 includes a cover portion 310 and a connection portion 320, and a liquid guide hole 311 is provided on the cover portion 310, and the liquid guide hole 311 is a through hole, so that the liquid guide hole 311 runs through the entire cover portion 310 along the thickness direction of the cover portion 310. When the cover portion 310 is stacked on the liquid guide member 400, the atomized matrix of the liquid can enter the liquid guide member 400 through the liquid guide hole 311. The connection portion 320 is protrudingly arranged at the edge of the cover portion 310, so that the connection portion 320 is protrudingly arranged at the edge in a direction that is angled with the thickness direction of the cover portion 310, for example, the connection portion 320 is protrudingly arranged at the edge of the cover portion 310 in a thickness direction perpendicular to the thickness of the cover portion 310. The number of the connection portions 320 is equal to the number of the upper limit members 120 of the base 100, so that the connection portions 320 and the limit members 120 form a one-to-one correspondence. The connecting portion 320 can be inserted into the locking hole 121 on the limiting member 120 and matched with the locking hole 121 , so that the cover plate 300 forms a detachable connection relationship with the base 100 through the connecting portion 320 .

[0042] Referring to FIG. 2 , FIG. 3 and FIG. 4 , in some embodiments, the cover plate 300 may further include reinforcing ribs 330 , and the number of the reinforcing ribs 330 may be two or more. The reinforcing ribs 330 are protruding along the thickness direction of the cover portion 310 on the surface of the cover portion 310 facing the liquid guide member 400 , so that the reinforcing ribs 330 protrude a certain height relative to the surface. When the cover plate 300 is connected to the base 100 , the reinforcing ribs 330 will abut against the liquid guide member 400 , and through the reinforcing ribs 330 , the reinforcing ribs 330 are closer to the substrate 110 relative to the cover portion 310 , so that the reinforcing ribs 330 generate a greater pressure against the liquid guide member 400 relative to the cover portion 310 , thereby increasing the pressure against the liquid guide member 400 by the entire cover plate 300 , and also generating sufficient adhesion between the liquid guide member 400 and the heating element 200 .

[0043] When the atomizer 10 is working, since the cover plate 300 stacked on the liquid guide member 400 is provided with a liquid guide hole 311, the liquid atomized matrix will flow into the liquid guide member 400 through the liquid guide hole 311, and the liquid guide member 400 will play a role in transmitting and caching the atomized matrix. When the heating element 200 is heated, since the heating element 200 and the liquid guide member 400 are stacked on each other, the atomized matrix in the liquid guide member 400 will absorb the heat of the heating element 200 and atomize to form an aerosol. During the process of the user inhaling the aerosol, the aerosol overflowing from the liquid guide member 400 will be output from the air guide hole 111 in the base 100, so that the aerosol is absorbed by the user.

[0044] In view of the planar structure of the heating element 200, the base 100, the heating element 200, the liquid guide member 400 and the cover plate 300 are stacked on each other along the thickness direction of the heating element 200, so that the entire atomizer 10 is roughly a flat structure, and the atomizer 10 can be abstracted as a plane. Compared with the traditional tubular atomizer 10, the atomizer 10 in the above embodiment has a relatively small thickness, so that the thin design of the atomizer 10 can be achieved.

[0045] The present application also provides an electronic atomization device, which includes the above-mentioned atomizer 10. The electronic atomization device has an inhalation channel 20, through which the aerosol is discharged, and the user can absorb the aerosol at the end of the inhalation channel 20. The inhalation channel 20 extends along a first direction, for example, the first direction can be a vertical direction. Referring to FIG3, during the installation process of the atomizer 10, the atomizer 10 can be installed horizontally. At this time, the plane where the heating element 200 is located extends along a second direction, and the second direction is a horizontal direction. Obviously, the first direction and the second direction are perpendicular to each other. Therefore, when the atomizer 10 is installed horizontally, the extension direction of the inhalation channel 20 is perpendicular to the plane where the heating element 200 is located, and the aerosol overflowing from the liquid guide 400 can enter the inhalation channel 20 through a roughly linear motion trajectory.

[0046] Referring to FIG. 5 , the atomizer 10 can also be installed vertically. In this case, the plane where the heating element 200 is located extends along the first direction, that is, the plane where the heating element 200 is located extends along the vertical direction, and the extension direction of the air inhalation channel 20 is parallel to the plane where the heating element 200 is located. Therefore, when the atomizer 10 is installed vertically, the extension direction of the air inhalation channel 20 is parallel to the plane where the heating element 200 is located, and the aerosol overflowing from the liquid guide 400 can first move along the plane perpendicular to the heating element 200, that is, move along the second direction, and then deflect 90°, so that the aerosol moves along the first direction to smoothly enter the air inhalation channel 20.

[0047] Therefore, by making the atomizer 10 abstracted as a plane, on the one hand, the thickness of the atomizer 10 can be reasonably reduced, and the thin design of the atomizer 10 can be achieved; on the other hand, compared with the traditional tubular atomizer 10 that can only be installed vertically, the atomizer 10 in the above embodiment can be installed horizontally and vertically, thereby achieving the diversity of the installation of the atomizer 10.

[0048] 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.

[0049] 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.
