[0037] In the description of the present invention, it should also be noted that unless otherwise clearly defined and limited, the terms "set", "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or a connection through an intermediate medium. It can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0038] As Figures 2 to 10 shown, it is the bottom rotation air adjustment structure of the present invention. As Figure 1 shown, it is arranged at the bottom of the electronic cigarette and is used to adjust the smoke volume of the electronic cigarette. The bottom rotation air adjustment structure includes a base 10 and an adjustment member 20 rotatably connected to the lower end of the base 10. A gas flow channel 30 is provided between the base 10 and the adjustment member 20; wherein the base 10 includes a bottom shell 12, the bottom shell 12 includes a side wall 18, a mounting portion 120 connecting the side wall 18, and a sealing seat 13 provided at the inner bottom of the mounting portion 120. An air intake gap 40 is provided between the lower end surface of the side wall 18 and the upper end surface of the adjustment member 20, and the air intake gap 40 communicates the gas flow channel 30 with the external atmosphere; an air intake groove 11 is provided through the sealing seat 13, and the air intake groove 11 communicates the gas flow channel 30 with the inside of the base 10; when the user uses the electronic cigarette, the flow direction of the external air is as Figure 10 shown, and it sequentially enters the inside of the electronic cigarette through the air intake gap 40, the gas flow channel 30, and the air intake groove 11, and forms smoke through the e-liquid atomizer. The adjustment member 20 is provided with a gas blocking protrusion 21, as Figure 9 and Figure 10As shown, the air-blocking bump 21 does not overlap with the air intake groove 11, and at this time, the air intake volume and the smoke volume of the electronic cigarette reach the maximum value. As Figure 6 and Figure 7 shown, at this time, the air-blocking bump 21 can block a part of the area of the air intake groove 11, thereby reducing the air intake volume of the electronic cigarette. The rotation of the adjusting member 20 relative to the base 10 drives the air-blocking bump 21 to rotate relative to the air intake groove 11 to adjust the blocking area of the air intake groove 11; during use, the smoke volume is determined by the air intake volume of the external air; the user rotates the adjusting member 20, and the air-blocking bump 21 moves with the adjusting member 20. During the movement displacement process, the blocked area of the air intake groove 11 changes accordingly, thereby adjusting the air intake volume of the external air. The adjustment is convenient and fast, and can meet the needs of users for different smoke volumes.

[0039] As Figure 7 and Figure 8 shown, a connecting bottom surface 120a is provided at the bottom of the mounting portion 120, and an inner bottom surface 20a is provided on the side of the adjusting member 20 facing the mounting portion 120. After the adjusting member 20 and the base 10 are assembled, the connecting bottom surface 120a abuts against the inner bottom surface 20a. At this time, an air inlet 40a is formed between the upper end surface of the adjusting member 20 and the lower end surface of the side wall 18. At the same time, there is an intermediate gap 40b between the outer wall of the mounting portion 120 and the inner wall of the adjusting member 20; the air inlet 40a and the intermediate gap 40b are interconnected to form an air intake gap 40. It can be understood that in other embodiments, when the size of the mounting portion 120 is small (satisfying the abutment of the connecting bottom surface 120a of the mounting portion 120 and the inner bottom surface 20a of the adjusting member 20), the air inlet 40a can be directly connected to the gas flow channel 30. In addition, a ring groove 24 is provided on the adjusting member 20 to ensure the passage of gas; specifically, the ring groove 24 is a part of the gas flow channel 30 and is connected to the air intake gap 40 and the air intake groove 11.

[0040] In some embodiments, the cross-sectional shape of the air intake groove 11 is arc-shaped, and the cross-sectional shape of the air-blocking bump 21 is also arc-shaped to cooperate with the rotation adjustment action of the adjusting member 20; wherein the width of the air-blocking bump 21 is greater than the width of the air intake groove 11 to ensure that a partial area of the air intake groove 11 can be blocked. Specifically, the arc length of the air-blocking bump 21 is less than the arc length of the air intake groove 11. When the air-blocking bump 21 completely enters the range of the air intake groove 11, there is still a ventilation gap left.

[0041] In some embodiments, the sealing seat 13 and the mounting portion 12 are connected by threads, and are specifically arranged at the bottom of the inner cavity of the electronic cigarette; the sealing seat 13 is made of silica gel material to ensure the airtightness between the sealing seat 13 and the bottom shell 12, and ensure that external gas can only enter the electronic cigarette through the gas flow channel 30, and ensure the air intake volume adjustment function.

[0042] Furthermore, as Figure 4As shown, a sunken clearance groove 131 is provided on the lower end surface of the sealing seat 13. The clearance groove 131 is arranged around the air inlet groove 11. The upper part of the air blocking bump 21 is movably connected within the clearance groove 131. Providing the clearance groove 131 can shorten the distance between the sealing seat 13 and the adjusting member 20, making the structure of the electronic cigarette more compact.

[0043] In some embodiments, as Figure 3 and Figure 4 shown, a connecting shaft 121 is provided at the central part of the lower end surface of the mounting seat 120. The connecting shaft 121 is specifically cylindrical. A connecting hole 22 is provided through the central part of the adjusting member 20. The connecting hole 22 cooperates with the connecting shaft 121 to realize the rotational connection between the adjusting member 20 and the bottom shell 12. Specifically, the inner wall of the connecting hole 22 is in close contact with the outer wall of the connecting shaft 121 to ensure the airtightness of the structure and prevent gas from passing through and affecting the air intake adjustment function.

[0044] In some embodiments, as Figure 5 shown, a plurality of arc-shaped connecting grooves 122 are opened on the inner bottom of the bottom shell 12. The connecting grooves 122 are arranged in a circumferential array around the connecting shaft 121. A connecting member 23 is fixedly provided on the upper end surface of the adjusting cover. The connecting member 23 is provided corresponding to the connecting grooves 122 one by one. When the electronic cigarette is assembled, the connecting member 23 is connected in cooperation with the connecting grooves 122 to realize the assembly connection between the adjusting member 20 and the bottom shell 12. In addition, the length of the connecting groove 122 is greater than the length of the connecting member 23. When the adjusting member 20 rotates relative to the bottom shell 12, the connecting member 23 can move along the connecting groove 122 to avoid interfering with the rotation of the adjusting member 20. Specifically, a barb portion 231 is provided at one end of the connecting member 23, and a connecting platform 123 is provided on one side of the connecting groove 122. The barb portion 231 is buckled on the connecting platform 123 to improve the connection stability.

[0045] In some embodiments, an arc-shaped limiting hole 124 is opened on the inner bottom of the bottom shell 12. The upper end of the air blocking soil block passes through the limiting hole 124 and always displaces within the limiting hole 124. The limiting hole 124 limits the displacement amount of the air blocking bump 21 to ensure that the air blocking bump 21 is always within the range of the air inlet groove 11.

[0046] As Figure 1 shown, the electronic cigarette involved in the present invention includes the above-mentioned bottom rotary air adjustment structure. When the user sucks the mouthpiece at the top of the electronic cigarette and manually rotates the adjusting member 20 at the bottom, the amount of smoke is adjusted.

[0047] Compared with the prior art, for the bottom rotation air-adjusting structure and the electronic cigarette according to the present utility model, a base 10 and an adjusting member 20 capable of relatively rotating are provided at the bottom of the electronic cigarette. A gas flow channel 30 is provided between the base 10 and the adjusting member 20. An air intake groove 11 communicating with the gas flow channel 30 is provided on the base 10. A gas-blocking convex block 21 is provided on the adjusting member 20. The gas-blocking convex block 21 is specifically located within the range of the air intake groove 11. Rotating the adjusting member 20 can drive the gas-blocking convex block 21 to displace, adjust the blocking area of the gas-blocking convex block 21 on the air intake groove 11, and further adjust the air intake amount of the electronic cigarette. Rotating the adjusting member 20 to adjust the air intake amount, the adjustment operation is simple. Adopting this gas flow scheme can prevent foreign matters such as water and dust from entering the interior of the electronic cigarette and improve the working reliability. At the same time, since this air-adjusting structure is provided at the bottom of the electronic cigarette, the appearance of the electronic cigarette is tidy and more beautiful.

[0048] The above only expresses the preferred technical solutions of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and the present utility model also intends to include these modifications and improvements.
