The fixing section 31 is sleeved outside the inner fixing sleeve 151, and the inner circumferential surface of the fixing section 31 is in sealing contact with the outer circumferential surface of the inner fixing sleeve 151, so as to realize a sealing connection relationship between the fixing section 31 and the inner fixing sleeve 151, and prevent the smoke liquid flowing into the check valve 30 through the inner fixing sleeve 151 from leaking between the connecting surface of the fixing section 31 and the inner fixing sleeve 151. The lower end face of the fixed section 31 abuts against the upper end face of the communicating piece 15, so that the fixed section 31 is connected with the communicating piece 15 in a sealing mode, and smoke liquid leakage is further prevented. The liquid inlet 321 is opened at the top of the deformation section 32, and the deformation section 32 can deform under the pressure action of the tobacco juice to open the liquid inlet 321, so that the tobacco juice enters the second tobacco juice channel after passing through the liquid inlet 321.

Meanwhile, the outer diameter dimension of the fixing section 31 is larger than that of the deforming section 32. The outer fixing sleeve 40 is roughly in a hollow cylindrical structure with an opening at the lower end, and the inner cavity of the outer fixing sleeve 40 is matched with the fixing section 31, so that when the outer fixing sleeve 40 is sleeved outside the one-way valve 30, a gap 401 is formed between the outer fixing sleeve 40 and the deformation section 32, and the gap 401 can store part of smoke liquid; the inner peripheral surface of part of the outer fixing sleeve 40 is in sealing contact with the outer peripheral surface of the fixing section 31, so that the sealing effect between the inner peripheral surface and the fixing section is realized, and the smoke liquid in the gap 401 is prevented from leaking.

The lower end face of the outer fixing sleeve 40 is abutted against the upper end face of the communicating piece 15, the upper end face of the outer fixing sleeve 40 is convexly provided with a tubular protruding part 402 along the axial direction of the outer fixing sleeve 40, the protruding part 402 is inserted into the lower end of the connecting pipe 14, and the protruding part 402 is communicated with the gap 401 and the connecting pipe 14, so that the connection relation between the outer fixing sleeve 40 and the connecting pipe 14 is realized.

In addition, the lower end of the fixed section 31 is provided with a fixed supporting leg 311 along the radial direction of the fixed section 31, the inner peripheral surface of the lower end of the outer fixed sleeve 40 is provided with a fixed groove 403 matched with the fixed supporting leg 311, when the outer fixed sleeve 30 is installed in place, the fixed supporting leg 311 is accommodated in the fixed groove 403, and the top wall of the fixed groove 403 abuts against the upper end surface of the fixed supporting leg 311, so that the fixed section 31 of the check valve 30 is pressed on the communicating piece 15, on one hand, the displacement of the check valve 30 caused by the pressure of the smoke liquid is avoided, on the other hand, the sealing performance between the check valve 30 and the communicating piece 15 is enhanced, and the effect of preventing the smoke liquid from leaking is further achieved.

In the present embodiment, the one-way valve 30 is made of silicone material, and is made of elastic material, and it should be understood that in other embodiments not shown, the one-way valve 30 may also be made of rubber or other materials, and is not limited herein.

When the pressurization mechanism 18 works, the smoke liquid enters the one-way valve 30 from the first smoke liquid channel, and then pushes the liquid inlet 321 open under the pressure of the smoke liquid to enter the second smoke liquid channel. In the process, the inner wall of the outer fixing sleeve 40 limits the deformation of the deformation section 32 on the one-way valve 30 in the range of restorable deformation, and prevents the deformation section 32 from failing due to overlarge deformation; in addition, the tobacco juice flowing into the check valve 30 through the first tobacco juice channel does not impact the fixing section 31 of the check valve 30, so that the fixing section 31 of the check valve 30 is prevented from being deformed irreversibly, and the sealing effect of the check valve 30 is ensured. When the pressurization mechanism 18 stops working, the liquid inlet 321 on the one-way valve 30 is closed due to the pressure of the smoke liquid, and the smoke liquid in the second smoke liquid channel is prevented from flowing back to the liquid storage cavity 161 through the first smoke liquid channel. Meanwhile, as the gap 401 is filled with the backflow tobacco juice quickly, the part of the tobacco juice has an extrusion effect on the deformation section 32, plays a promoting role in resetting the one-way valve 30, and can quickly close the liquid inlet 321, so that the one-way valve 30 can quickly respond, and the sensitivity of the one-way valve is improved.

According to the above, when the pressurization mechanism 18 stops operating, the one-way valve 30 can prevent the backflow of the smoke liquid in the second smoke liquid channel, that is, the second smoke liquid channel is filled with the smoke liquid, and when the pressurization mechanism 18 is restarted next time, the pressurization mechanism 18 can immediately press the smoke liquid into the atomizer, so that the dry burning of the atomizer caused by the time difference of the flow of the smoke liquid in the smoke liquid channel can be effectively prevented.
