[0045] In addition, if the terms "first", "second" and the like are used only to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0046] It should be noted that the features in the embodiments of the utility model can be combined with each other without conflict.

[0047] Please refer to Figures 1-4 , Figure 1 the structure schematic diagram of the integrally formed atomizing piece shell 100 under the first visual angle provided by the embodiment; Figure 2 the structure schematic diagram of the integrally formed atomizing piece shell 100 under the second visual angle provided by the embodiment; Figure 3 the structure schematic diagram of the atomizing device 200 provided by the embodiment; Figure 4 is Figure 3 the local enlarged view of A in the figure. The X direction shown in the figure is the first direction, the Y direction is the second direction, and the Z direction is the third direction. The first direction, the second direction and the third direction are perpendicular to each other.

[0048] It can be understood that the first direction is the length direction of the integrally formed atomizing piece shell 100, the second direction is the thickness direction of the integrally formed atomizing piece shell 100, and the third direction is the width direction of the integrally formed atomizing piece shell 100.

[0049] The utility model provides a kind of atomizing device 200, which comprises ceramic ring piece 210, at least one metal diaphragm 220 and integrally formed atomizing device 200, integrally formed atomizing device 200 has two oppositely arranged first side walls 110, two oppositely arranged second side walls 120 and one third side wall 130;First side wall 110, second side wall 120 and third side wall 130 are perpendicular to each other.

[0050] Two first side walls 110, two second side walls 120 and third side wall 130 form containing cavity 140 with opening 141;Containing cavity 140 has two first parts 142 and one second part 143, second part 143 is located between two first parts 142;Wherein, metal diaphragm 220 is detachably contained in first part 142, and ceramic ring piece 210 is detachably contained in second part 143.

[0051] It can be understood that the metal diaphragm 220 and the ceramic ring piece 210 are combined together to form an atomizing piece, and the integrally formed atomizing piece shell 100 is provided with a containing cavity 140 to contain the atomizing piece and can protect the atomizing piece. Moreover, the atomizing shell in the embodiment is integrally formed, and the structure is more stable, so that the protection effect on the atomizing piece can be improved.

[0052] The containing cavity 140 has an opening 141, so that when the atomizing piece is installed, the atomizing piece can enter the containing cavity 140 from the opening 141, and when the atomizing piece is disassembled, the atomizing piece can also be taken out from the opening 141. Therefore, the atomizing piece is more convenient to install and disassemble, and the installation, maintenance and replacement efficiency of the atomizing piece can be improved.

[0053] It should be noted that the ceramic ring piece 210 in the embodiment has a hollow, and the diameter of the metal diaphragm 220 is greater than the length of the first part 142 in the first direction, and the metal diaphragm 220 has elasticity, so that after the metal diaphragm 220 is installed, the metal diaphragm 220 is in an arc shape, so that the middle part of the metal diaphragm 220 is clamped in the hollow of the ceramic ring piece 210, and the end of the metal diaphragm 220 abuts against the inner wall of the first part 142; in addition, the distance between the inner walls on the opposite sides of the second part 143 in the first direction is less than the distance between the inner walls on the opposite sides of the first part 142 in the first direction, so that the metal diaphragm 220 can also abut against the inner wall of the second part 143.

[0054] Therefore, the metal diaphragm 220 and the ceramic ring piece 210 in the embodiment can be not welded with the integrally formed atomizing piece shell 100 or integrally formed together, and through the interaction force generated when the metal diaphragm 220 abuts against the ceramic ring piece 210 and the integrally formed atomizing piece shell 100, the metal diaphragm 220 and the ceramic ring piece 210 are fixed.

[0055] Moreover, the number of the metal diaphragm 220 in the embodiment is two, and the two metal diaphragms 220 are respectively detachably contained in the two first parts 142. In other embodiments, the number of the metal diaphragm 220 can be one, and the metal diaphragm 220 is contained in any one of the two first parts 142.

[0056] When the metal diaphragm 220 is disassembled, force can be applied to the exposed metal diaphragm 220, so that the interaction force between the metal diaphragm 220 and the ceramic ring piece 210 and the integrally formed atomizing piece shell 100 is unbalanced, so that the metal diaphragm 220 is taken out, and then the ceramic ring piece 210 is taken out.

[0057] According to the above, in the embodiment, each first side wall 110 is provided with a through hole 111 so that the accommodation cavity 140 is in communication with the outside, so that the metal film 220 can be in contact with water in the outside, and then the water is converted into water mist particles, so as to achieve the purpose of atomization.

[0058] Further, in the embodiment, since the thickness of the metal film 220 is smaller than the thickness of the ceramic ring 210, the distance between the two opposite inner walls of the first part 142 in the second direction is smaller than the distance between the two opposite inner walls of the second part 143 in the second direction; so that the metal film 220 and the ceramic ring 210 can be more stably accommodated in the accommodation cavity 140, and the metal film 220 and the ceramic ring 210 are prevented from falling off.

[0059] It should be noted that the second direction is the thickness direction of the third side wall 130, so the first direction and the second direction are perpendicular.

[0062] Further, each first side wall 110 is provided with a through hole 112, and the through hole 112 is used for passing a wire to connect the wire and the metal film 220.

[0063] The wire is connected with the metal film 220 through the through hole 112, so that the metal film 220 is electrified, and then the metal film 220 can convert water in the outside into water mist particles.

[0064] It should be noted that the through hole 112 in the embodiment is circular, and in other embodiments, the shape of the through hole 112 can also be a variety of shapes such as a sector.
