The working principle and the beneficial effects of the scheme are as follows: in an initial state, the clamping block 917 is connected in the clamping groove 916 in a clamping manner, the movable baffle 901 closes a smoke through hole of the main body 7, when a user uses an electronic cigarette product, after a power supply is turned on, the first electromagnetic block 918 and the second electromagnet 919 are electrified, the first electromagnetic block 918 and the second electromagnet 919 are attracted to be close to each other, the position of the second electromagnet 919 is fixed, the first electromagnetic block 918 moves towards the second electromagnet, the second electromagnet 919 drives the sliding block 915 to move, the sliding block 915 drives the clamping block 917 to leave the clamping groove 916, the second spring 920 is compressed, the sliding block 915 drives the second rack 921 to move, the second rack 921 drives the second straight gear 922 to rotate clockwise through meshing connection, the second straight gear 922 drives the top block 923 to move upwards through meshing connection, the top block 923 pushes the lock block 914 to move upwards, the movable baffle 901 rotates, the smoke through hole of the main body 7 is opened, and the user can normally use the electronic cigarette, with the use of the electronic cigarette, smoke passing through the smoke through hole of the main body 7 transmits partial heat to the air bag 911 through the heat conducting rod 912, the air bag 911 is heated and expanded, the air bag 911 pushes the sliding plate 908 to move downwards, the first spring 910 is compressed, the sliding plate 908 drives the first rack 909 to move downwards, the first rack 909 drives the first straight gear 906 to rotate through meshing connection, the first straight gear 906 drives the first rotating shaft 904 to rotate, the first rotating shaft 904 drives the second bevel gear 905 to rotate, the second bevel gear 905 drives the first bevel gear 902 to rotate, the first bevel gear 902 drives the movable baffle 901 to rotate anticlockwise, because the first electromagnetic block 918 is in a state of continuous energization to the second electromagnet 919 in the use process, the top block 923 is always in a high position and drives the movable baffle 901 to rotate anticlockwise in cooperation with the heated expansion of the air bag, and it is ensured that the movable baffle 901 cannot rebound due to the first spring 910 and the second spring 920, closing the smoke aperture of the body 7. When the user finishes using the electronic cigarette, the first electromagnetic block 918 is electrified and disconnected to the second electromagnet 919, the attraction force between the first electromagnetic block 918 and the second electromagnet 919 disappears, the second spring 920 rebounds to drive the top block 923 to return to the initial position, at this time, because the air bag 911 expands when heated and can not immediately contract to the initial state because of the disappearance of a heat source, the smoke through hole of the closed main body 7 still keeps the connected state, the residual smoke in the smoke through hole of the main body 7 can be emitted by utilizing the time for gradually cooling the air bag 911, when the air bag 911 is completely cooled to the initial state, the rebounding action of the first spring 910 pushes the movable baffle 901 to rotate to the limit position, the movable baffle 901 drives the lock block 914 to extend into the third transmission chamber 913, the clamping block 917 is clamped into the clamping groove 916 again, the movable baffle 901 finishes sealing the smoke through hole of the main body 7, and avoids using the electronic cigarette without using, inside dust or other debris got into the electron cigarette through the through-smoking hole of main part 7, guaranteed the cleanliness in the through-smoking hole of main part 7, also more sanitary.

In one embodiment of the present invention, further comprising:

the alarm gives out an acousto-optic signal for giving out an alarm prompt to a user;

the detection module is used for detecting the fatigue strength safety factor of the spring part in the electronic cigarette;

the controller, controller electric connection in siren and detection module, the controller is used for according to the fatigue strength safety factor control of spring part in the electron cigarette of detection module transmission the work of siren, its step includes:

step 1: calculating the rigidity of the spring part according to the formula (1);

in the formula, K is the shear elastic modulus of the spring part, D is the section diameter of the spring wire of the spring part, n is the effective number of turns of the spring part, and D is the spring intermediate diameter of the spring part;

step 2: calculating the maximum cyclic shear stress and the minimum cyclic shear stress generated in the spring part according to the formula (2);

in the formula, P₁Is the mounting load of the spring element, P₂The load is the maximum load of the spring element during working, pi is a constant and is 3.14;

and step 3: calculating the fatigue strength safety factor of the spring part according to the formula (3);

in the formula, τ₀Is the pulsating cyclic shear fatigue limit, L, of the spring element₁Is the pre-tension deformation of the spring element, L₂The maximum tensile deformation of the spring element;

and 4, step 4: calculating the fatigue strength safety factor S of the spring part and the design safety factor S of the fatigue strength of the spring part according to the formula (3)_PComparing, if S is less than or equal to S_PThe controller controls the alarm to give an alarm if S > S_PAnd the controller controls the alarm not to work.

The working principle and the beneficial effects of the scheme are as follows:

spring part is after long-time use, because stretch out and draw back the deformation repeatedly, causes mechanical fatigue accumulation very easily, in case the fatigue strength safety factor of spring part is less than the design safety factor of this spring part fatigue strength, can cause on the one hand to use inconveniently, and on the other hand can have the potential safety hazard.

The detection module calculates a fatigue strength safety factor of the spring part by constructing a reasonable algorithm, compares the fatigue strength safety factor with a design safety factor of the fatigue strength of the spring part, outputs comparison information to the controller, controls the work of the alarm according to the comparison information, and if S is less than or equal to S_PThe controller controls the alarm to give an alarm if S > S_PThe controller controls the alarm to be out of work, the user can judge the fatigue strength safety factor of the spring part in the electronic cigarette very visually according to the working state of the alarm, and when the user receives the acousto-optic alarm signal sent by the alarm, the spring part in the electronic cigarette needs to be overhauled and replaced.
