[0039] As Figures 1 to 2 shown, an electronic cigarette according to an embodiment of the present utility model includes a condensate recovery structure 100. As Figures 3 to 8 shown, the condensate recovery structure 100 is used to recover the condensate formed by the condensation of the smoke during the use of the electronic cigarette.

[0040] Please refer to Figures 3 to 5 , the condensate recovery structure 100 includes a housing 11, a connection seat 12 assembled on the inner top of the housing 11, a mouthpiece 13 assembled on the housing 11, and an oil absorption cotton 15; a cavity 14 is provided on one side of the connection seat 12 facing the housing 11, and an air inlet hole 16 communicating with the cavity 14 is provided at the bottom of the connection seat 12; the mouthpiece 13 communicates with the cavity 14 and the air inlet hole 16; the oil absorption cotton is arranged in the cavity 14, and a through groove 151 is formed in the middle of the oil absorption cotton 15, and the inner wall of the through groove 151 forms an adsorption surface 152.

[0041] During the use of the electronic cigarette, the smoke formed by atomization passes through the connection seat 12 and the mouthpiece 13 in sequence and is sucked by the user at the mouthpiece 13. Since the working temperature at the mouthpiece 13 is lower than the working temperature of the atomization component, the smoke will condense to form condensate when passing through the connection seat 12 and the mouthpiece 13. Among them, the condensate will converge at the air inlet hole 16 and the mouthpiece 13; both the air inlet hole 16 and the mouthpiece 13 are in contact with the oil absorption cotton 15, so the condensate formed by the condensation of the smoke will be adsorbed by the oil absorption cotton 15. At the same time, a through groove 151 is formed in the center of the oil absorption cotton 15, which helps the condensate to diffuse outward inside the oil absorption cotton 15; in addition, the free condensate can also be adsorbed by the oil absorption cotton 15 through the adsorption surface 152.

[0042] Specifically, a connecting post 111 is provided inside the outer shell 11. The connecting post 111 is a vertically penetrating structure. One end of the connecting post 111 is connected to the external environment, and the other end is communicated with the cavity 14. The suction nozzle 13 is assembled in the connecting post 111, and the bottom of the connecting post 111 abuts against the oil-absorbing cotton 15. The connecting post 111 provides an installation position for the suction nozzle 13, and the suction nozzle 13 is assembled in the connecting post 111 by threads to achieve the assembly connection with the outer shell 11. During use, the condensate formed in the suction nozzle 13 flows to the bottom of the connecting post 111 under the action of gravity and is finally adsorbed by the oil-absorbing cotton 15. Further, an inclined liquid guide surface 112 is provided at the lower end opening of the connecting post 111 to prevent the condensate from accumulating at the lower end of the connecting post 111 and affecting the recovery of the condensate.

[0043] Please refer to Figures 5 to 6 , in order to increase the recovery amount of the condensate, a condensate accommodating groove 17 is opened at the inner bottom of the connecting seat 12, and the condensate accommodating groove 17 is communicated with the through groove 151. Specifically, the condensate accommodating groove 17 and the air inlet hole 16 are respectively provided at two ends of the bottom surface of the cavity 14 and are spaced apart. For the convenience of description, as Figure 8 shown, the end of the oil-absorbing cotton 15 close to the air inlet hole 16 is the proximal end 15a, and the end of the oil-absorbing cotton 15 close to the condensate accommodating groove 17 is the distal end 15b; after the condensate converging at the air inlet hole 16 and the suction nozzle 13 is adsorbed by the oil-absorbing cotton 15; at this time, the density of the condensate at the proximal end 15a of the oil-absorbing cotton 15 is greater than the density of the condensate at the distal end 15b of the oil-absorbing cotton 15. Therefore, the condensate will diffuse from the proximal end 15a towards the distal end 15b. When the oil-absorbing cotton 15 is nearly saturated, the condensate will enter the condensate accommodating groove 17 and be recovered.

[0044] Specifically, as Figure 6 and Figure 7 shown, a convex block 18 is provided at the lower end of the connecting seat 12, and the condensate accommodating groove 17 is arranged in the convex block 18. The convex block 18 is used for the structural support inside the electronic cigarette, and arranging the condensate accommodating groove 17 in the convex block 18 can save space.

[0045] Specifically, as Figure 8 shown, a plurality of liquid drainage channels 153 are provided inside the oil-absorbing cotton 15. The end of the liquid drainage channel 153 facing the air inlet hole 16 is the liquid suction end 154, and the end of the liquid drainage channel 153 facing the condensate accommodating groove 17 is the liquid discharge end 155; the liquid drainage channels 153 play a role in guiding the condensate, and the condensate can diffuse along the liquid drainage channels 153 from the liquid suction end 154 to the liquid discharge end 155, and then diffuse from the proximal end 15a of the oil-absorbing cotton 15 to the distal end 15b of the oil-absorbing cotton 15 and finally enter the condensate accommodating groove 17. Further, in order to increase the diffusion speed, the liquid drainage channels 153 are arranged in parallel and evenly spaced.

[0046] Specifically, the top surface of the oil-absorbing cotton 15 is a diversion surface 19, and the diversion surface 19 is inclined. One end of the diversion surface 19 close to the air inlet hole 16 is higher than the end close to the condensate receiving groove 17. A height difference is formed at both ends of the diversion surface 19, which helps to provide the speed for the condensate to diffuse from the proximal end 15a towards the distal end 15b.

[0047] Specifically, the diversion surface 19 is provided with a guiding groove 191. One end of the guiding groove 191 is connected to the condensate receiving groove 17, and the other end of the guiding groove 191 is also connected to the condensate receiving groove 17. During use, part of the condensate is not adsorbed by the oil-absorbing cotton 15 and accumulates on the surface of the diversion surface 19. Under the action of the guiding groove 191, the condensate can flow along the guiding groove 191 into the condensate receiving groove 17.

[0048] Please refer to Figures 1 to 2 , which is an electronic cigarette of the present utility model. It includes the above-mentioned condensate recovery structure 100, and also includes an oil storage cotton 200 assembled at the lower end of the connection seat 12, an atomizing core 300 arranged inside the oil storage cotton 200, and a battery assembly 500 for supplying power to the atomizing core 300. An air outlet pipe 400 is arranged inside the oil storage cotton 200. The lower end of the air outlet pipe 400 is communicated with the atomizing core 300, and the upper end of the air outlet pipe 400 is communicated with the cavity 14 through the air inlet hole 16. The battery assembly 500 supplies power to the atomizing core 300. The atomizing core 300 heats up to atomize the e-liquid in the oil storage cotton 200 into smoke. The smoke passes through the air outlet pipe 400, the connection seat 12 and the mouthpiece 13 in sequence and is inhaled by the user. The condensate formed when the smoke passes through the connection seat 12 and the mouthpiece 13 will be adsorbed by the oil-absorbing cotton 15.

[0049] Compared with the prior art, for the condensate recovery structure and the electronic cigarette involved in the present utility model, the condensate recovery structure 100 is provided with a connection seat 12, and an oil-absorbing cotton 15 is arranged inside the connection seat 12. The oil-absorbing cotton 15 can adsorb the condensate converging at the mouthpiece 13, avoiding the condensate from being inhaled by the user and seeping into the battery main board, improving the use experience and safety. Specifically, a hole is opened in the central part of the oil-absorbing cotton 15 to expand the contact area between the condensate and the oil-absorbing cotton 15, which is beneficial to the outward diffusion of the condensate and improves the recovery efficiency of the oil-absorbing cotton 15. At the same time, a condensate receiving groove 17 is arranged on the connection seat 12 to recover the condensate overflowing from the oil-absorbing cotton 15 and further recover the condensate. The electronic cigarette provided with the condensate recovery structure 100 can prevent the user from inhaling the condensate and optimize the taste.

[0050] The above only expresses the preferred technical solutions of the present utility model, and the description thereof 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 variations.
