Referring to fig. 1 and fig. 2 in combination, fig. 1 is a schematic structural diagram of an electronic atomization device according to some embodiments of the present utility model, and fig. 2 is a schematic structural diagram of a host in the embodiment of fig. 1.

The electronic atomizing device 1 may include a main body 10 and an atomizer 20. The atomizer 20 may be mounted on the host 10 or may be separated from the host 10. It should be understood that the terms "comprising" and "having," and any variations thereof, as used in the specification and the appended claims, are intended to cover non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.

In one embodiment, a slot 101 is provided on one side of the host 10. The atomizer 20 may be mounted in the tank 101 of the host 10 to achieve docking with the host 10, where the host 10 may control the atomizer 20 to atomize. In other words, the atomizer 20 can be moved into or out of the tank 101. The atomizer 20 may be electrically connected to the built-in power supply of the host computer 10 when the atomizer 20 is moved into the tank 101. When the atomizer 20 moves out of the tank 101, the atomizer 20 is separated from the main body 10.

Alternatively, one host 10 may be adapted to a plurality of atomizers 20, such that a user may realize a continuous use of the electronic atomizing device 1 by replacing an atomizer 20 when one of the atomizers 20 is damaged or the atomizing medium is insufficient. Similarly, one atomizer 20 can be adapted to a plurality of hosts 10, so that when one of the hosts 10 is damaged or has insufficient power, a user can realize continuous use of the electronic atomizing device 1 by replacing the host 10.

It should be noted that the meaning of "a plurality" in the description of the present utility model is two or more, unless explicitly defined otherwise.

In an embodiment, the slot 101 of the host 10 may extend from the surface of the housing to the interior of the housing, so that the atomizer 20 may be partially accommodated in the host 10 when moving into the slot 101, and thus the size of the electronic atomizing device 1 may be reduced in the direction in which the atomizer 20 moves into or out of the slot 101.

Of course, the through hole 103 may be a through hole having both ends penetrating to the side wall and the bottom wall of the main body 10, respectively.

In some embodiments, the through hole 103 may be a through hole with two ends penetrating through the top wall and the bottom wall, the side wall and the bottom wall, different parts of the top wall, different parts of the side wall, or different parts of the bottom wall, respectively, so that the host 10 takes different forms when hung.

Referring to fig. 3 in combination, fig. 3 is a schematic structural diagram of a host according to some embodiments of the present utility model.

In some embodiments, the slot 101 of the host 10 has a bottom wall 1011 and a first through hole 104 penetrating the bottom wall 1011. The first through hole 104 can be used as an air outlet hole of the host 10, and air in the host 10 can enter the tank 101 through the first through hole 104. When the atomizer 20 is assembled in the tank 101, the gas fed into the tank 101 through the first through hole 104 may further flow into the atomizer 20.

The main body 10 may further include an electrode terminal 210 penetrating the bottom wall 1011. One end of the electrode terminal 210 is exposed to the space within the tub 101 to collide with the atomizer 20 when the atomizer 20 is moved into the tub 101. The internal power supply of the main unit 10 may be electrically connected to the atomizer 20 through the electrode terminals 210, so that the atomizer 20 may be supplied with electricity required for atomization.

The host 10 may also include a magnetic attraction member 220 provided on the bottom wall 1011. The magnetic component 220 may be fixed to the bottom wall 1011 by means of adhesion, clamping, or the like, so as to adsorb the atomizer 20 when the atomizer 20 moves into the tank 101, so as to improve the docking stability of the atomizer 20 and the host 10.

Wherein the magnetic attraction member 220 is at least partially composed of a magnetic material. The atomizer 20 moved into the tank 101 has a magnetic attraction structure that can be mated with the magnetic attraction member 220. For example, the magnetic attraction member 220 is a magnet, and the end of the atomizer 20 facing the tank 101 has a magnet or steel that can be attracted to the magnetic attraction member 220, so that the atomizer 20 can be attracted to the magnetic attraction member 220 when moved into the tank 101.

Optionally, the magnetic attraction member 220 is disposed around the periphery of the electrode terminal 210, so as to save the assembly space on the bottom wall 1011. The magnetic attraction member 220 may be in a ring shape, a square ring or other ring shape, or a plurality of magnetic structural members which are arranged at intervals and are matched with each other to surround the electrode terminal 210.

The second circuit board 720 may be further fixed to the bottom 510 of the second cover 500 by using a fixing member such as a screw or a pin, so as to further improve the stability of the charging structure of the host 10.

In summary, when the atomizer is in butt joint with the host, the atomizer can move into the groove body of the host in the first pipe body along the axial direction of the host, so that the size of the electronic atomization device in the axial direction of the host is reduced; the host of the electronic atomization device can also form a first accommodating cavity and a second accommodating cavity by utilizing the first pipe body and the second pipe body which are arranged side by side of the accommodating piece and matching with the first cover body and the second cover body, and a plurality of structural members are distributed in the first accommodating cavity and the second accommodating cavity, so that the axial size of the host is reduced; in addition, the first pipe body and the second pipe body can also have different outer diameters so as to form the undulating outer side surface of the host machine by matching with the first cover body and the second cover body, thereby improving the holding feeling of the host machine.

The foregoing description is only of embodiments of the present utility model, and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes using the descriptions and the drawings of the present utility model or directly or indirectly applied to other related technical fields are included in the scope of the present utility model.
