[0004] When people use the existing device, the outer cover needs to be removed. However, since the outer cover is often connected to the outer shell through a friction cover to achieve the protection effect on the cigarette holder, this often causes the outer cover to fall off accidentally.

[0032] 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.

A first tension spring 14 and a sealing block 15 are movably connected inside the exhaust duct 10, and a first elastic spring 16 is fixedly connected to the outer side of the sealing block 15. A PCB board 25 is arranged inside the silicon wheat airflow sensor 21, and a negative pressure adjustment hole 24 is opened inside the silicon wheat airflow sensor 21. A MEMS 26 is arranged above the PCB board 25. The operator moves the slide cover 2 downward, which will cause the connecting piston 3 to move downward, thereby compressing the air pressure inside the first cavity 4 and the first pipe 5. When the bottom of the slide cover 2 contacts the inclined surface of the slider 6, the slider 6 will move away from one side of the slide cover 2, thereby connecting the first pipe 5 and the second pipe 7 through the connecting hole 8. At this time, the air pressure inside the second cavity 9 will increase rapidly, thereby lifting the piston connecting block 12 and the cigarette holder 11, so that the top of the cigarette holder 11 moves out to the top of the shell 1, and the operation is completed.

[0034] It is worth noting here that Fig. 9 , Figure 2 , Figure 6 , Figure 8 As shown: the PCB board 25 is arranged inside the silicon wheat airflow sensor 21. Considering that the starting negative pressures of different MEMS 26 are different, if the pressure formed by the incoming airflow is less than 300Pa, the negative pressure adjustment hole 24 is blocked; if the pressure is greater than 300Pa, the negative pressure adjustment hole 24 is opened; therefore, the negative pressure adjustment hole 24 arranged on the PCB board 25 is convenient for the device to match MEMS 26 of different sizes or designs, so that when the user applies suction to the silicon wheat airflow sensor 21 through the suction nozzle 11 to smoke, the silicon wheat airflow sensor 21 senses the air pressure inside the electronic cigarette during the user's smoking process, which is convenient for the user to inhale.

[0035] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 8As shown, the injection structure 18 includes a T-shaped piece 181 and an inclined block 182, the outer surface of the T-shaped piece 181 is movably connected to the bottom of the inner cavity of the shell 1 near the piston 3, the bottom of the inclined block 182 near the piston 3 is fixedly connected to a second tension spring 183, the bottom of the middle of the inner cavity of the shell 1 is movably connected to a cylindrical block 184 and a cylindrical block 185, the bottom of the inner cavity of the cylindrical block 185 is fixedly connected to a top block 186, the bottom of the inner cavity of the injection bottle 19 is fixedly connected to a fixing frame 189, the inner cavity of the fixing frame 189 is movably connected to a sealing plug 187, the outer surface of the sealing plug 187 is movably sleeved with a third tension spring 188, and the top of the cylindrical block 185 is fixedly connected to a second elastic spring 1810;

The planar slider 6 cooperates with one end of the bottom of the slide cover 2; the design of the slider 6 serves as a barrier between the first pipe 5 and the second pipe 7, thereby preventing the cigarette holder 11 from moving upward and contacting the slide cover 2 when the slide cover 2 is opened. When the connecting hole 8 on the slider 6 is connected with the second pipe 7 and the first pipe 5 respectively, the increased air pressure in the first pipe 5 and the slider 6 is quickly passed into the second cavity 9, and then when the slide cover 2 is opened, the cigarette holder 11 is quickly lifted up by the increased pressure inside the second cavity 9 to complete the operation.

At the same time, when the slide cover 2 is reset, the pressure inside the first pipe 5 and the slider 6 is reduced. Due to the elastic force of the spring sheet 17, the slider 6 will be reset. At the same time, the action of the first tension spring 14 will reset the mouthpiece 11. At this time, the gas inside the second cavity 9 will be discharged from the exhaust duct 10 and the circular holes on the sealing block 15, so that the device can be reset and used.

[0038] like Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 8 As shown, the inclined block 182 is movably connected to the inner cavity of the shell 1, the bottom of the front and rear ends of the outer surface of the T-shaped piece 181 cooperates with the inclined block 182, the second tension spring 183 is fixedly connected to the shell 1 near the end connected to the piston 3, and the top of the inclined block 182 away from the side connected to the piston 3 is located below the cylindrical block 184, and the inclined block 182 cooperates with the cylindrical block 184; the design of the second tension spring 183 plays a role in resetting the inclined block 182, and the elastic force of the second elastic spring 1810 plays a role in resetting the cylindrical block 185.

At the same time, the hose 20 and the cylindrical block 185 are matched so that when the cylindrical block 185 moves up and down, the bottom end of the hose 20 moves with the cylindrical block 185.

[0040] The working principle and use process of the present invention:

[0041] First, the operator moves the slide cover 2 downward, which will cause the connecting piston 3 to move downward, thereby compressing the air pressure inside the first cavity 4 and the first pipe 5. When the bottom of the slide cover 2 contacts the inclined surface of the slider 6, the slider 6 will move away from the side of the slide cover 2, thereby connecting the first pipe 5 and the second pipe 7 through the connecting hole 8. At this time, the air pressure inside the second cavity 9 will increase rapidly, thereby lifting the piston connecting block 12 and the cigarette holder 11, so that the top of the cigarette holder 11 moves out to the top of the housing 1, and the operation is completed;

[0042] At the same time, when the bottom of the connecting piston 3 contacts the top of the T-shaped piece 181, the descent of the connecting piston 3 will squeeze the T-shaped piece 181 to move downward, squeeze the inclined block 182 and make the inclined block 182 away from the end of the sliding cover 2 to squeeze the cylindrical block 184, so that the cylindrical block 184 squeezes the cylindrical block 185 and the top block 186 to move upward, and the sealing plug 187 will move upward. At this time, the inner cavity of the liquid injection bottle 19 will be connected to the hose 20 through the cylindrical block 185, and the silicon wheat airflow sensor 21 will connect the connecting pipe 22 and the silicon wheat airflow sensor 21, so that the mist is transported to the inside of the bellows 13 through the connecting pipe 22 and finally transported to the mouthpiece 11 to complete the operation.
