[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] It should be noted that the descriptions of "first", "second", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their 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 addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0032] Different from the electrode connection structure in the prior art which cannot support large current, occupy a small area and have high electrical connection reliability, the present invention provides an electrode sheet, an atomizer and an atomizing device.

[0033] Please refer to Figure 1 , Figure 1 Schematic diagram of the structure of an electrode sheet according to an embodiment of the present invention. In the embodiment of the present invention, the electrode sheet comprises: an electrode body 72 arranged in a ring shape, and at least one elastic connecting arm 71 arranged in the electrode body 72, one end of the elastic connecting arm 71 is connected to the electrode body 72, and the other end of the elastic connecting arm 71 forms a gap 73 with the electrode body 72 and protrudes from the electrode body 72.

[0034] Specifically, the electrode sheet is elastically electrically connected to the second contact piece through the elastic connecting arm 71, avoiding the use of hard metal connection between the two, which can improve the reliability of the electrical connection and avoid the problems of open circuit and false connection; on the other hand, the electrode body 72 has a large contact area with the first contact piece, so a large current can pass.

[0035] In this embodiment, the electrode body 72 is arranged in a ring shape, and at least one elastic connecting arm 71 is formed in the inner circle of the electrode body 72. Of course, considering the stability of the electrical connection, the number of elastic connecting arms 71 can be set to two or more, and two or more elastic connecting arms 71 are evenly distributed. At this time, the entire electrode sheet is a stacked ring electrode. One end of the elastic connecting arm 71 is suspended. When connected, the suspended end of the elastic connecting arm 71 is elastically squeezed on the second contact member to achieve elastic electrical contact. Furthermore, a protrusion is formed in the middle of the elastic connecting arm 71, which is away from the electrode body and elastically abuts against the second contact member. The provision of the protrusion can improve the mechanical strength of the elastic connecting arm 71 and ensure the reliability of the elastic connection.

[0036] Furthermore, the elastic connecting arm 71 is arranged in a bent sheet shape as a whole. In this way, the elastic connecting arm 71 forms a sheet-pressing structure, and when the first contact piece and the second contact piece are close to each other, the elastic connecting arm 71 of the electrode sheet is pressed against the second contact piece. In addition, the sheet-like structure not only reduces the assembly space, but also has a better deformation effect.

[0037] Specifically, at least two arc-shaped recesses 73 distributed in a ring shape are formed in the electrode body 72, and the elastic connecting arm 71 is arranged corresponding to the arc-shaped recess 73, and one end of the elastic connecting arm 71 is fixed to one side of the arc-shaped recess 73, and the other end of the elastic connecting arm 71 is suspended from the other side of the arc-shaped recess 73.

[0038] In this embodiment, the number of the elastic connecting arms 71 is at least two, one end of the elastic connecting arm 71 is connected to one side of the arc-shaped notch 73, the other end of the elastic connecting arm 71 is connected to the other side of the arc-shaped notch 73, and the entire elastic connecting arm 71 protrudes from the electrode body 72 to facilitate electrical connection with the second contact member. It can be understood that the number of the elastic connecting arms 71 can be three, four, etc., and the specific number can be set according to actual requirements.

Among them, the base 10, the atomizer core 50 and the electrode sheet 70 constitute the atomizer. Please refer to the following embodiments for the specific structure.

[0040] In an embodiment of the present invention, the atomizer comprises:

[0041] A base 10, wherein a mounting hole 11 is provided at the bottom of the base 10;

When the electrode sheet is applied to the atomizer, the first contact member is specifically the base of the atomizer, and the second contact member is specifically the core seat of the atomizer core.

[0045] In this embodiment, the outer side of the base 10 is sleeved with an outer cover 40. The power electrode 60 and the base 10 can be connected to the positive and negative electrodes of the power supply respectively, and the power electrode 60 directly abuts and electrically contacts the core of the atomizer core 50; the base 10 is electrically connected to the core seat of the atomizer core 50 through the electrode sheet 70, so that the normal operation of the atomizer core 50 can be achieved.

On the other hand, the side of the electrode sheet 70 away from the base 10 is elastically abutted with the core seat, that is, the electrode sheet 70 is squeezed and contacted with the core seat, so that the problems of easy circuit breaking and virtual connection caused by the hard connection of the metal can be avoided, and the reliability of the electrical connection is improved; the electrode sheet 70 is in surface contact with the core seat, and the contact area is large, which can support the passage of large current and meet the demand for high power; in addition, the electrode sheet 70 is roughly annular, occupies a small hole area, can save assembly space, and is conducive to the design of miniaturization of the product.

[0046] Please refer to Figure 7 , Figure 7 Schematic diagram of the combination of the power electrode, the first insulating ring, the electrode sheet, the core electrode and the second insulating ring of the present invention.
