Referring to fig. 3, the atomizing cup 1 includes a cup cover 10, a cover body 11, a cup body 12, a flow guide structure 13, and a collision body 14. Wherein the body 11 has a nebulization chamber 111, in which nebulization chamber 111 the aerosol-generating substrate is impinged by a high-velocity gas stream to generate an aerosol. The cup cover 10 is provided with a mist outlet 101, and the mist outlet 101 is used for guiding generated aerosol out. Wherein, the cup cover 10 and the cover body 11 can be detachably connected or integrally formed. The cup cover 10 and the cup body 11 cooperate to form a mist outlet channel. One end of the mist outlet channel is communicated with the atomizing cavity 111, and the other end is communicated with the mist outlet 101.

Cup 12 sets up in the one end that the lid 10 was kept away from to lid body 11, can be for dismantling the connection between lid 10, lid body 11 and the cup 12, also can be integrated into one piece. The cup 12 has a reservoir (not shown) for storing the aerosol-generating substrate, and an end of the cup 12 adjacent the host 2 is adapted to be removably connected to the host 2.

The collision body 14 is arranged in the atomization cavity 111, and the collision body 14 is coaxial with and spaced from the flow guide structure 13, so that the gas and the aerosol-generating substrate from the flow guide structure 13 collide with the collision body 14 at high speed to realize atomization.

Specifically, when the electronic atomization device is operated, the gas guided out of the gas guide tube and the aerosol-generating substrate guided out of the liquid guide tube impact the collision body 14 at high speed in the atomization cavity 111, so that atomization is realized.

Since the air pump 30 generates a large amount of heat during operation, in order to effectively dissipate heat of the air pump 30, referring to fig. 4 and 5, a first air flow channel 34 is formed between the air pump 30 and the housing 20, when the electronic atomization device operates, the air pump 30 operates simultaneously, and the external air flows through the outer surface of the air pump 30 through the first air flow channel 34 and then enters the compression cavity 310 of the air pump 30. It can be understood that, when the external air flows through the first air flow channel 34, specifically, the external air flows through the external surface of the air pump 30, so as to take away the heat generated by the air pump 30, thereby dissipating heat of the air pump 30, and the air pump 30 preheats the external air flowing through the external surface thereof at the same time, when the external air enters the compression cavity 310, the external air has a certain temperature, thereby reducing the power consumption required by the air pump 30 when compressing the air, realizing the preheating of the air, and improving the comfort level of the user.

Referring to fig. 2, the housing 20 further has an air inlet 25 communicating with the first air flow path 34, and when the air pump 30 is operated, the external air enters the first air flow path 24 through the air inlet 25.

In an embodiment, the first end of the air inlet pipe 32 is communicated with the compression chamber 310, and the second end of the air inlet pipe 32 is communicated with the first air flow passage 34, so that the external air can sequentially enter the compression chamber 310 through the air inlet 25, the first air flow passage 34 and the air inlet pipe 32, and thus when the air pump 30 enters air, the air pump 30 is cooled, and independent heat dissipation holes do not need to be formed, thereby ensuring the overall attractiveness of the electronic atomization device. Moreover, the air pump 30 can pump the air in the first air flow channel 34, i.e. the air between the air pump 30 and the housing 20, so as to accelerate the air flow on the surface of the air pump 30, which is beneficial to heat dissipation of the air pump 30. More specifically, heat dissipation from the motor in the air pump 30 is facilitated.

In one embodiment, air inlet 25 is a charging interface, such as a USB interface, at an end of housing 20 distal from air inlet tube 32. In other embodiments, the air inlet 25 may be a gap between the main body 21 and the main body cover 22, an air hole specially formed in the housing 20 for air intake, or a heat dissipation hole in the housing 20. It is understood that heat dissipation can be continued when the air pump 30 stops operating by using the heat dissipation holes of the housing 20 as the air inlet 25.

In an alternative embodiment, to ensure the heat dissipation effect on the air pump 30, the air inlet 25 is disposed in the lower region of the housing 20, i.e., the side of the middle of the housing 20 away from the atomizing cup 1, so that the air entering from the air inlet 25 flows through at least a half region of the outer surface of the air pump body 31.

In another embodiment, the air inlet 25 is disposed at one end of the housing 20 away from the air inlet pipe 32 or away from the atomizing cup 1, that is, the tail end or the bottom end of the air pump 30, so that the air entering from the air inlet 25 can flow through the entire outer surface of the air pump body 31 before entering the air inlet pipe 32, and the heat dissipation effect on the air pump 30 is achieved to the greatest extent.

In an embodiment, the main body 2 further includes a sealing member 60, and the sealing member 60 is disposed on an outer side of the air inlet pipe 32 and at least partially contacts the housing 20 to seal and fix the air inlet pipe 32. The sealing element 60 has a second air flow channel 61, and the air inlet pipe 32 is communicated with the first air flow channel 34 through the second air flow channel 61, so that the outside air can only enter the air pump 30 through the first air flow channel 34 of the second air flow channel 61, but cannot enter the air pump 30 through other modes, and the heat dissipation effect on the air pump 30 is ensured.

In an alternative embodiment, the second air flow channel 61 is a plurality of air flow channels opened inside the sealing member 60, and the air in the first air flow channel 34 passes through the plurality of air flow channels inside the sealing member 60 to enter the air inlet pipe 32.

In other alternative embodiments, the inner surface of the seal 60 and/or the outer surface of the air inlet tube 32 may have grooves, the seal 60 and the air inlet tube 32 cooperate to form a second air flow passage 61, and air in the first air flow passage 34 may enter the air inlet tube 32 through the gap between the seal 60 and the air inlet tube 32.

In some alternative embodiments, the material of the sealing member 60 may be silicone, rubber, or a combination thereof, as long as it can perform a sealing function.

5-6, the sealing member 60 includes a hollow cylindrical body 62 and a top cover 63 connected to each other, the hollow cylindrical body 62 is at least partially sleeved on the outer surface of the air inlet pipe 32, and the hollow cylindrical body 62 and the air inlet pipe 32 are matched to form a second air flow passage 61; the top cover 63 is spaced apart from the second end of the air inlet pipe 32 to form an air passing space, and the external air in the second air flow passage 61 enters the air inlet pipe 32 through the air passing space.

The top cover 63 includes a cover 631 and a projection 632. The protruding portion 632 is inserted into the hollow cylindrical body 62, and a gas passing space is formed by one end of the protruding portion 632 close to the gas inlet pipe 32, the second end of the gas inlet pipe 32 and the inner surface of the hollow cylindrical body 62.

Wherein, the hollow cylindrical body 62 and the top cover 63 are of a split structure and are detachably connected; alternatively, the hollow cylinder 62 may be integrally formed with the top cover 63 (as shown), but is not limited thereto. Because the top cover 63 is too small, the top cover may not be found after the top cover 63 accidentally falls off, and the hollow cylindrical body 62 and the top cover 63 are integrally formed, so that the top cover 63 can be conveniently and newly installed after the top cover 63 accidentally falls off.

In one embodiment, referring to fig. 5 and 7, the inner surface of the hollow cylindrical body 62 has a first groove 621, and the first groove 621 cooperates with the outer surface of the air inlet pipe 32 to form the second air flow passage 61. In another embodiment, the outer surface of the air inlet pipe 32 has a first groove 621 (not shown), and the first groove cooperates with the inner surface of the hollow cylindrical body 62 to form the second air flow passage 61. In yet another embodiment, both the inner surface of the hollow cylindrical body 62 and the outer surface of the air inlet pipe 32 have a first groove 621, and the first groove 621 of the inner surface of the hollow cylindrical body 62 and the first groove 621 of the outer surface of the air inlet pipe 32 cooperate to form the second air flow passage 61. The selection is specifically selected according to actual needs, and is not limited herein.

The extending direction of the first groove 621 may be designed to be circuitous along the inner surface of the hollow cylindrical body 62, and the extending direction of the first groove 621 may also be parallel to the height direction of the air inlet pipe 32. It can be understood that when the extending direction of the first groove 621 is parallel to the height direction of the air inlet duct 32, the length of the first groove 621 is shortest, and the air intake resistance is smallest.

It will also be appreciated that the inner surface of the hollow cylindrical body 62 also has raised formations 622, the hollow cylindrical body 62 abutting the outer surface of the air inlet pipe 32 via the raised formations 622. It can be understood that the hollow cylindrical body 62 abuts against the air inlet pipe 32 through the raised structures 622 on the inner surface, and the gap between the raised structures 622 corresponds to the first groove 621, and forms the second air flow passage 61 by surrounding with the outer surface of the air inlet pipe 32 and the inner surface of the hollow cylindrical body 62.

The hollow cylindrical body 62 may be in line contact with the air inlet pipe 32. Referring to fig. 8, the protrusion 622 includes a plurality of protrusions 6221 spaced along the circumference of the hollow cylinder 62. In the present embodiment, the protruding strip 6221 extends from the bottom of the hollow cylindrical body 62 to the middle of the hollow cylindrical body 62, and the protruding strip 6221 is not provided on the upper portion of the hollow cylindrical body 62, so that the top cover 63 can be sealed. Alternatively, referring to fig. 9, the protrusion 622 includes a plurality of protruding rings 6222 spaced along the axial direction of the hollow cylindrical body 62, and each protruding ring 6222 has at least one notch 6223, and the notch 6223 is used to conduct the air passages on both sides of the protruding ring 6222, so as to communicate the first air flow passage 34 with the air inlet 25.

The hollow cylindrical body 62 may be in point contact with the intake pipe 32. For example, referring to fig. 10, the protrusion 622 includes a plurality of protrusions 6224 spaced along the circumference of the hollow cylinder 62, and the shape of the protrusions 6224 may be circular, rectangular, triangular, etc.

In one embodiment, referring to fig. 5, the hollow cylindrical body 62 and the outer surface near one end of the air pump body 31 are further provided with an annular flange 623. Specifically, the radius of the annular flange 623 is greater than that of the hollow cylindrical body 62, and the annular flange 623 is disposed between the housing 20 and the end of the air pump body 31, so as to limit the sealing element 60 under the cooperation of the housing 20, and prevent the sealing element 60 from moving in a direction away from the air pump 30. For example, the seal 60 is prevented from moving away from the air pump 30 due to vibration when the air pump 30 is in operation.

In one embodiment, referring to fig. 13, to increase the intake air flow rate, the outer surface of the air pump body 31 has a second groove 313, and the second groove 313 cooperates with the inner surface of the housing 20 to form the first air flow passage 34. In another embodiment, the inner surface of the housing 20 has a second groove 313 (not shown), and the second groove 313 cooperates with the outer surface of the air pump body 31 to form the first air flow channel 34. In yet another embodiment, both the outer surface of the air pump body 31 and the inner surface of the housing 20 have the second groove 313, and the second groove 313 of the outer surface of the air pump body 31 and the second groove 313 of the inner surface of the housing 20 cooperate to form the first air flow passage 34.

Referring to fig. 5, in an embodiment, the main body 2 further includes an air filter 70 disposed at the second end of the air inlet pipe 32, i.e., at the air inlet of the air inlet pipe 32, and accommodated in the air passing space formed between the top cover 63 and the air inlet pipe 32, for filtering the outside air entering the air pump 30, so as to prevent impurities, particles and the like from entering the compression cavity 310 and damaging the air pump 30. And the top cover 63 simultaneously fixes and protects the filter member 70.

The host 2 and the electronic atomization device provided by the application comprise a shell 20 and an air pump 30, wherein the shell 20 is provided with an accommodating cavity; the air pump 30 is accommodated in the accommodating cavity, and a first air flow channel 34 is formed between the air pump and the housing 20; wherein, when the air pump 30 is operated, the external air can flow through the outer surface of the air pump 30 through the first air flow passage 34. With the above arrangement, when the air pump 30 operates, the external air can flow through the outer surface of the air pump 30 to take away the heat generated by the operation of the air pump 30.

Since the air pump 30 generates relatively large vibration and noise during operation, the air compression type electronic atomization device using the air pump 30 generates corresponding vibration and noise during operation.
