[0039] Please see Figure 1 , Figure 2 As shown, this application provides an electronic atomizing device, including a base assembly 1, a housing 2, a top cover assembly 3, and an atomizing core 4.

[0040] In some embodiments, the outer shell 2 is mounted on the base assembly 1; the upper cover assembly 3 is mounted on the outer shell 2; and the atomizing core 4 is mounted on the base assembly 1 and located inside the outer shell 2.

[0041] In this embodiment, the upper cover assembly 3 and the outer shell 2 are designed separately, with the upper cover assembly 3 mounted on the outer shell 2; in other embodiments, the upper cover assembly 3 and the outer shell 2 can also be designed as a single piece, thereby improving the connection and sealing between the upper cover assembly 3 and the outer shell.

[0042] In this embodiment, the electronic atomizing device further includes a mouthpiece assembly 5, which is mounted on the side of the upper cover assembly 3 away from the outer shell 2.

[0043] Please see Figures 2 to 4 As shown, in some embodiments, the upper cover assembly 3 includes an upper cover 31, the upper cover 31 having a mating groove 311 on the side facing the base assembly 1, and the bottom of the mating groove 311 having a through air intake hole 312.

[0044] One end of the atomizing core 4 is mounted on the base assembly 1, and at least part of the end of the atomizing core 4 away from the base assembly 1 is inserted into the docking groove 311. In this embodiment, the end of the atomizing core 4 is press-fitted with the docking groove 311 to achieve a sealed installation of the atomizing core 4 and the docking groove 311. A gas guiding channel 41 is formed inside the atomizing core 4, and the gas guiding channel 41 is coaxially connected with the air intake hole 312. The diameter of the gas guiding channel 41 on the side closer to the docking groove 311 is larger than the diameter of the air intake hole 312.

[0045] Please see Figure 3 As shown, in this embodiment, a liquid storage cavity is formed between the inner wall of the upper cover 31, the inner wall of the outer shell 2, and the outer wall of the atomizing core 4.

[0046] Please see Figure 5 As shown, in this embodiment, when the electronic atomizing device is in atomization mode, water vapor and other substances contact the side wall of the air guide channel 41 and condense to form condensate. When the user inhales the atomized aerosol, the condensate moves along the side wall of the air guide channel 41 towards the mouthpiece assembly 5 under suction. Figure 5 As indicated by arrow 100; since the diameter of the suction hole 312 in this application is smaller than the diameter of the air guiding channel 41, when the condensate moves along the side wall of the air guiding channel 41 towards the nozzle assembly 5 and reaches the docking groove 311, the bottom of the docking groove 311 acts as a barrier to the condensate, and the condensate flows back under the action of gravity, as shown ... Figure 5 As indicated by arrow 200, this is to prevent condensate from entering the user's mouth along with the aerosol.

[0047] The electronic atomizing device provided in this application embodiment can position and install the atomizing core 4 by setting a docking groove 311 on the upper cover 31, thereby improving the installation efficiency and quality of the atomizing core 4. At the same time, by setting an air intake hole 312 with a diameter smaller than that of the air guide channel 41 in the docking groove 311, a baffle is formed at the air outlet end of the air guide channel 41, which blocks the condensate formed on the side wall of the air guide channel 41, thereby improving the user experience.

[0048] Please see Figure 4 As shown, in this embodiment, the bottom of the docking groove 311 is provided with at least one return groove 313, the return groove 313 is arranged around the air intake hole 312, and the return groove 313 is at least partially connected to the air guide channel 41.

[0049] In this embodiment, there are four return channels 313, which are arranged around the air intake 312 and are separated by baffles.

[0050] Please seeFigure 5 As shown, in this embodiment, the condensate moves along the sidewall of the air guide channel 41 towards the nozzle assembly 5 under the action of suction. Figure 5 As indicated by arrow 100, when the condensate enters the return tank 313, the suction disappears, and therefore the condensate flows back under gravity, as shown in the image. Figure 5 As indicated by arrow 200, this is to prevent condensate from entering the user's mouth along with the aerosol.

[0051] Please see Figure 6 As shown, in this embodiment, when the electronic atomizing device is inverted, the atomizing liquid will move along the side wall of the air guide channel 41 towards the mouthpiece assembly 5 under the action of gravity, as... Figure 6 As indicated by arrow 300, the liquid enters the return tank 313 for storage to prevent leakage. When the electronic atomizing device is upright, the atomizing liquid stored in the return tank 313 will flow back to the storage chamber under the action of gravity.

[0052] In this embodiment, a return groove 313 is provided around the air intake 312. During normal use, it can collect condensate and return the condensate to the atomizing core 4. When the electronic atomizing device is inverted, it can also collect and store the atomized liquid that leaks down the side wall of the air guide channel 41, thus preventing leakage of the atomized liquid.

[0053] Please see Figure 3 As shown, in some embodiments, a liquid storage cavity is formed between the inner wall of the top cover 31, the inner wall of the outer shell 2, and the outer wall of the atomizing core 4.

[0054] Please see Figure 2 , Figure 4 As shown, in some embodiments, the side wall of the upper cover 31 is provided with at least one mounting groove 314, and at least one air inlet hole 315 is passed through the mounting groove 314, and the air inlet hole 315 is in communication with the liquid storage chamber.

[0055] In this embodiment, the side wall of the upper cover 31 is provided with two mounting grooves 314, which are symmetrically arranged on opposite sides of the upper cover 31. Three air inlet holes 315 pass through the mounting grooves 314.

[0056] In this embodiment, by providing the air inlet 315, air can be supplied to the liquid storage chamber during the use of the electronic atomizing device, thereby improving the overall airflow performance of the electronic atomizing device, increasing the air circulation rate, and maintaining the air pressure balance in the liquid storage chamber.

[0057] Please see Figure 2As shown, in some embodiments, the upper cover assembly 3 further includes at least one first seal 32, one first seal 32 being installed in one of the mounting grooves 314, and the first seal 32 having at least one through hole 321 communicating with the air inlet 315.

[0058] In this embodiment, the upper cover assembly 3 includes two first sealing elements 32, which are respectively installed in two mounting grooves 314. The first sealing elements 32 are provided with three through holes 321, and each through hole 321 is connected to a corresponding air inlet 315.

[0059] In this embodiment, the first sealing element 32 is used to seal the air supply hole 315 to prevent leakage of atomizing liquid when the electronic atomizing device is replenished with air.

[0060] Please continue reading. Figure 2 As shown, in some embodiments, the upper cover assembly 3 further includes an air regulating cover 33, which is rotatably mounted on the upper cover 31. The air regulating cover 33 is provided with an air regulating groove 331, which is located at the same height as the mounting groove 314.

[0061] In this embodiment, an elastic sealing ring is also provided between the gas regulating cover 33 and the upper cover 31. The sealing between the gas regulating cover 33 and the upper cover 31 is achieved by setting the Tangxing sealing ring.

[0062] In this embodiment, the rotation of the air regulating cover 33 relative to the upper cover 31 adjusts the overlap between the air regulating groove 331 and the mounting groove 314, thereby adjusting the opening degree of a single air replenishment hole 315 or adjusting the number of air replenishment holes 315 open, thus adjusting the air replenishment amount of the electronic atomizing device during use, and achieving the effect of maintaining the air pressure balance in the liquid storage chamber.

[0063] Please continue reading. Figure 2 As shown, in some embodiments, the outer shell 2 is provided with a liquid injection hole 21, which is connected to the liquid storage chamber. The electronic atomizing device also includes a second sealing member 6, which is installed on the liquid injection hole 21 to seal the liquid injection hole 21.

[0064] Please see Figure 2 , Figure 3 As shown, in some embodiments, the base assembly 1 includes a base 11 and a bracket 12, the bracket 12 being mounted on the base 11, and the outer shell 2 being sealed on the base 11 and supported by the bracket 12.

[0065] In this embodiment, an elastic sealing ring is installed on the outer wall of the base 11. When the outer shell 2 is installed on the base 11, the outer shell 2 squeezes the elastic sealing ring, causing the elastic sealing ring to deform, thereby achieving a waterproof seal between the outer shell 2 and the base 11.

[0066] In this embodiment, an elastic sealing ring is provided on the base 11, and the sealing effect on one side of the electronic atomizing device base 11 is achieved by the cooperation between the outer shell 2 and the elastic sealing ring; in addition, the structural strength of the electronic atomizing device is improved by the provision of the bracket 12.

[0067] In this embodiment, the base assembly 1 further includes at least one magnetic member 13, which is mounted on the side of the base 11 away from the outer shell 2.

[0068] The embodiments of this application aim to ensure the structural and electrical connection stability of the electronic atomizing device with the power supply component.

[0069] Please continue reading. Figure 2 , Figure 3 As shown, the suction nozzle assembly 5 includes a suction nozzle 51 and a filler 52.

[0070] The suction nozzle 51 is sealed on the side of the upper cover 31 away from the outer shell 2. The side wall of the end where the suction nozzle 51 is connected to the upper cover 31 is fitted with several elastic sealing rings. When the suction nozzle 51 is installed on the upper cover 31, the seal between the suction nozzle 51 and the upper cover 31 is achieved by squeezing the elastic sealing rings.

[0071] In this embodiment, the suction nozzle 51 is provided with an air outlet channel 511, which is connected to the air guide channel 41 through the air intake hole 312.

[0072] Please see Figure 3 As shown, the filler 52 is installed between the suction nozzle 51 and the upper cover 31. In this embodiment, the filler 52 is disposed between the elastic sealing ring and the upper cover 31.

[0073] In this embodiment, the filling element 52 ensures the sealing and connection stability between the mouthpiece 51 and the top cover 31. At the same time, the filling element 52 can guide the heated and atomized liquid to smoothly enter the user's mouth, improving the user experience.
