Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic atomization, and in particular to an atomization main body and an electronic atomization device. BACKGROUND

[0002] Tobacco products, such as cigarettes, cigars, and the like, burn tobacco during use to produce tobacco smoke. Attempts have been made to provide alternatives to these burning tobacco products by creating products that release compounds without burning.

[0003] Examples of such products are heat-not-burn devices that release compounds by heating, rather than burning, a material. For example, the material can be tobacco or other non-tobacco products, which can or can not contain nicotine. As another example, there are aerosol provision devices, such as so-called electronic atomization devices. These devices typically contain a liquid that is heated to cause it to vaporize, thereby producing an inhalable aerosol. The liquid can contain nicotine and / or flavorants and / or an aerosol generating substance (e.g., glycerol).

[0129] For the purposes of the present application, the present application will be described in greater detail below, with reference made to the accompanying drawings and the detailed description.

[0130] The present application proposes an electronic atomization device for atomizing a liquid substrate to generate an aerosol.

[0131] Figures 1 to 8 A schematic view of an electronic atomization device is shown in one embodiment; in this embodiment, the electronic atomization device comprises a first body 100 and a second body 200; the second body 200 is mounted within the first body 100.

[0132] In some embodiments, the first body 100 and the second body 200 exist independently of each other before they are assembled; and after the first body 100 is combined with the second body 200, they jointly define the complete electronic atomization device for a user to use or to inhale the aerosol.

[0133] In some embodiments, the second body 200 is an atomization body for atomizing a liquid substrate to generate an aerosol; the first body 100 is for mounting or holding the second body 200, and for a user to operate to selectively control the atomizer in the second body 200 to generate the aerosol. In some embodiments, before the first body 100 and the second body 200 are assembled or exist independently; the second body 200 can generate the aerosol alone for a user to use or to inhale, and the first body 100 cannot generate the aerosol alone for a user to use or to inhale.

[0134] In some embodiments, the second body 200 is entirely removable or replaceable from the first body 100 after the first body 100 and the second body 200 are assembled. Alternatively, in yet other embodiments, the second body 200 is not detachable or replaceable from the first body 100 after the first body 100 and the second body 200 are assembled; they are entirely recycled or discarded after the liquid substrate within the second body 200 is consumed.

[0135] According to Figures 1 to 12 As shown, the first body 100 includes:

[0136] a proximal end 110 and a distal end 120 opposite in the longitudinal direction; a first side 130 and a second side 140 opposite in the width direction; and, a front side 150 and a back side 160 opposite in the thickness direction. In use, the proximal end 110 is the end closer to the user for ease of puffing; the distal end 120 is the end further away from the user. In some embodiments, as shown in Figures 1 to 12 As shown, the first body 100 can be flat in shape. The length dimension of the first body 100 is greater than the width dimension, which is greater than the thickness dimension.

[0137] According to Figures 1 to 12 As shown, the first body 100 includes:

[0138] the mouthpiece 20 and the main housing 10 are arranged in series in the longitudinal direction; the mouthpiece 20 is proximate to and defines the proximal end 110, and the main housing 10 is proximate to and defines the distal end 120. In some embodiments, the main housing 10 and / or the mouthpiece 20 can be formed of a metal or an alloy, such as stainless steel, aluminum, or the like; other suitable materials include various plastics, metal-plated plastics, ceramics, and the like.

[0139] According to Figures 1 to 12 As shown, the main housing 10 is generally configured in the shape of a frame or a box extending in the longitudinal direction. The main housing 10 has a longitudinally extending receiving cavity 11 formed or defined therein; the second body 200 can be received and retained within the receiving cavity 11. The receiving cavity 11 is open from the front side 150 to the back side 160. In embodiments, the receiving cavity 11 is open at the front side 150 and the back side 160.

[0140] According to Figures 1 to 6 As shown, the first body 100 further includes:

[0141] The pin 131 and the pin 141 are used to connect the second body 200 with the main housing 10 of the first body 100. In embodiments, the pin 131 and the pin 141 are arranged along the width direction of the first body 100. And, the pin 131 and the pin 141 are arranged in alignment in the width direction. Wherein, the pin 131 penetrates through the first side 130 into the accommodating cavity 11, and at least partially extends into the second body 200 to connect with the second body 200; the pin 141 penetrates through the second side 140 into the accommodating cavity 11, and at least partially extends into the second body 200 to connect with the second body 200.

[0142] According to Figures 1 to 12 As shown in FIG. 13 and / or FIG. 14, the pin 131 and / or the pin 141 provide the rotational connection of the second body 200 with the first body 100; and in embodiments, the second body 200 can rotate or flip around the first axis along the width direction of the electronic atomization device, which is defined by the pin 131 and / or the pin 141. Alternatively, the second body 200 can rotate or flip around the first axis along the width direction of the electronic atomization device, which is defined by the pin 131 and / or the pin 141.

Thus, after assembly, the second body 200 is kept connected with the first body 100 by the pin 131 and / or the pin 141, to prevent the power supply mechanism of the second body 200 from being detached from the first body 100.

[0143] According to Figures 1 to 12 As shown in FIG. 13 and / or FIG. 14, a user can operate, for example, press the second body 200 from the front side 150 and / or the rear side 160, to drive the second body 200 to rotate or flip around the first axis along the width direction of the electronic atomization device, which is defined by the pin 131 and / or the pin 141, as shown by the arrow P11 in FIG. 13 and / or FIG. 14.
