When the clamping frame 2012 and the clamping block 2013 are clamped, the return spring 2014 is in a contracted state.

[0027] When in use, the connecting rod 2011 is fixed under the engagement of the card block 2013 and the card frame 2012, so that the blocking piece 202 covers the outside of the oil inlet hole 102, blocks the oil inlet hole 102, separates the oil core, and prevents the atomizer 103 from being in contact with the smoke oil for a long time. If the electronic cigarette shell 1 needs to be inhaled, the connecting rod 2011 can be pulled. Since the reset spring 2014 is in a contracted state when the card frame 2012 is engaged with the card block 2013, when the connecting rod 2011 is pulled to separate the card block 2013 from the card frame 2012, the reset spring 2014 is reset, driving the connecting rod 2011 to move upward, driving the blocking piece 202 upward, and making the blocking piece 202 away from the oil inlet hole 102, so that the smoke oil enters the inside of the atomizer 103 through the oil inlet hole 102, and is heated into smoke by the atomizer 103, so as to realize the leak-proof function of the leak-proof structure.

[0028] Furthermore, if Figure 4 As shown, the electronic cigarette shell 1 and the bottom shell 101 are detachably connected through the maintenance mechanism 3, the interior of the maintenance mechanism 3 includes a maintenance component 301 and a sealing ring 302, the interior of the bottom shell 101 is adhered with a sealing ring 302, the electronic cigarette shell 1 and the bottom shell 101 are detachably connected through the maintenance component 301, the maintenance component 301 is composed of an internal thread groove 3011, an external thread ring 3012 and a fixing ring 3013, a fixing ring 3013 is fixed to the bottom of the electronic cigarette shell 1, the surface of the fixing ring 3013 is tightly fitted with the surface of the sealing ring 302, an external thread ring 3012 is fixed to the surface of the bottom shell 101, the inner wall of the external thread ring 3012 is bonded and fixed to the surface of the sealing ring 302, an internal thread groove 3011 is opened at the bottom of the electronic cigarette shell 1, and the internal thread groove 3011 and the external thread ring 3012 are threadedly matched with each other.

[0029] When in use, the electronic cigarette shell 1 and the bottom shell 101 are fixed under the thread cooperation of the internal thread groove 3011 and the external thread ring 3012. At the same time, the fixing ring 3013 is inserted into the bottom shell 101 along the internal thread groove 3011, and the electronic cigarette shell 1 and the bottom shell 101 are sealed under the action of the sealing ring 302. If maintenance is required, the bottom shell 101 can be rotated to quickly separate the internal thread groove 3011 and the external thread ring 3012, and then the electronic cigarette shell 1 and the inside of the bottom shell 101 can be inspected to realize the function of the leak-proof structure that is easy to maintain.

[0030] Furthermore, if Figure 5As shown, the interior of the electronic cigarette shell 1 is provided with a high-efficiency sealing mechanism 4, and the high-efficiency sealing mechanism 4 is composed of an oil-proof pad 401 and an oil-proof component 402.

[0034] At this time, the electronic cigarette shell 1 and the bottom shell 101 are fixed under the thread cooperation of the internal thread groove 3011 and the external thread ring 3012. At the same time, the fixing ring 3013 is inserted into the bottom shell 101 along with the internal thread groove 3011, and the electronic cigarette shell 1 and the bottom shell 101 are sealed under the action of the sealing ring 302. If maintenance is required, the bottom shell 101 can be rotated to quickly separate the internal thread groove 3011 and the external thread ring 3012. Then the electronic cigarette shell 1 and the inside of the bottom shell 101 can be inspected to realize the function of facilitating maintenance of the leak-proof structure, thereby improving the convenience of maintenance of the leak-proof structure and finally completing the use of the leak-proof structure.
