When the main body is inserted into the power supply device, the main body further includes a third part exposed out of the power supply device, and the third part is further provided with at least one buckle part. The technical scheme of present disclosure can effectively facilitate the user to plug in/out the atomizing device and effectively prevent the nozzle cover from detaching from the main body. ## Claims ### Claim 1 An atomizing device of an electronic cigarette, the atomizing device comprising: a nozzle cover; and a main body comprising a first part, a second part, and a third part, wherein the first part is covered by the nozzle cover, the second part is configured to be inserted into a power supply device of the electronic cigarette, and the third part is exposed outside when the main body is inserted into the power supply device, wherein the third part is further provided with at least one buckle part, wherein the main body is convexly provided with at least one limiting block on the second part, wherein when the main body is inserted into the power supply device, the limiting block will abut against the outer edge of the power supply device, and the surface of the limiting block facing away from the second part is exposed to form the third part. ### Claim 2 (depends on 1) The atomizing device of claim 1, wherein the outer surface of the limiting block protrudes beyond the outer surface of the power supply device to form the buckle part. ### Claim 3 (depends on 1) The atomizing device of claim 1, wherein the outer surface of the limiting block is lower than or flush with the outer surface of the power supply device, and the limiting block is provided with a groove abutted by inserted finger of user and forms the buckle part. ### Claim 4 (depends on 3) The atomizing device of claim 3, wherein the main body is provided with a chamber for storing tobacco juice, wherein the wall of the groove facing towards the notch is a transparent area, and the transparent area is used for a user to check the tobacco juice stored in the chamber. ### Claim 5 (depends on 1) The atomizing device of claim 1, wherein the power supply device is provided with an avoidance groove matching the side structure of the limiting block, wherein when the second end of the main body is inserted into the power supply device, the limiting block will locate third part the avoidance groove. ### Claim 6 (depends on 5) The atomizing device of claim 5, wherein one end of the limiting block away from the nozzle cover is an arc-shape, and the avoidance groove is in a corresponding arc-shape. ### Claim 7 (depends on 1) The atomizing device of claim 1, wherein the nozzle cover is provided with a notch matching the side structure of the limiting block, and the limiting block partially locate in the notch. ### Claim 8 (depends on 7) The atomizing device of claim 7, wherein one end of the limiting block facing towards the nozzle cover is an arc-shape, and the notch is in a corresponding arc-shape. ### Claim 9 (depends on 1) The atomizing device of claim 1, wherein two opposite ends of the nozzle cover are provided with connecting slots, and the main body is correspondingly provided with two connecting clips, wherein the nozzle cover can buckle-connects with the main body as well as cover the first part, wherein two opposite surfaces of the second part of the main body are convexly provided with the limiting blocks, and the two limiting blocks form the third part, wherein the two limiting blocks and the two connecting clips locate on each adjacent outer surface of the main body respectively. ### Claim 10 (depends on 9) The atomizing device of claim 9, wherein the main body includes a long axis and a short axis, wherein the two connecting clips are oppositely provided on the two outer surfaces of side main body along the direction of the long axis, and the two limiting blocks are oppositely provided on the two outer surfaces of side main body along the direction of the short axis. ### Claim 11 An electronic cigarette comprising: a power supply device; and an atomizing device that includes: a nozzle cover; and a main body comprising a first part, a second part, and a third part, wherein the first part is covered by the nozzle cover, the second part is configured to be inserted into a power supply device of the electronic cigarette, and the third part is exposed outside when the main body is inserted into the power supply device, wherein the third part is further provided with at least one buckle part, wherein the main body is convexly provided with at least one limiting block on the second part, wherein when the main body is inserted into the power supply device, the limiting block will abut against the outer edge of the power supply device, and the surface of the limiting block facing away from the second part is exposed to form the third part. ### Claim 12 An atomizing device of an electronic cigarette, the atomizing device comprising: a nozzle cover; and a main body comprising a first part, a second part, and a third part, wherein the first part is covered by the nozzle cover, the second part is configured to be inserted into a power supply device of the electronic cigarette, and the third part is exposed outside when the main body is inserted into the power supply device, wherein the third part is further provided with at least one buckle part, wherein two opposite ends of the nozzle cover are provided with connecting slots, and the main body is correspondingly provided with two connecting clips, wherein the nozzle cover can buckle-connects with the main body as well as cover the first part, wherein two opposite surfaces of the second part of the main body are convexly provided with the limiting blocks, and the two limiting blocks form the third part, wherein the two limiting blocks and the two connecting clips locate on each adjacent outer surface of the main body respectively. ### Claim 13 An electronic cigarette comprising: a power supply device; and an atomizing device that includes: a nozzle cover; and a main body comprising a first part, a second part, and a third part, wherein the first part is covered by the nozzle cover, the second part is configured to be inserted into a power supply device of the electronic cigarette, and the third part is exposed outside when the main body is inserted into the power supply device, wherein the third part is further provided with at least one buckle part, wherein two opposite ends of the nozzle cover are provided with connecting slots, and the main body is correspondingly provided with two connecting clips, wherein the nozzle cover can buckle-connects with the main body as well as cover the first part, wherein two opposite surfaces of the second part of the main body are convexly provided with the limiting blocks, and the two limiting blocks form the third part, wherein the two limiting blocks and the two connecting clips locate on each adjacent outer surface of the main body respectively.
