Technical Field

The embodiment of the application relates to the technical field of electronic atomization, in particular to an electronic atomization device and a power supply mechanism for the electronic atomization device.

Background

Smoking articles (e.g., cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. Attempts have been made to replace these tobacco-burning products by making products that release the compounds without burning.

An example of such a product is a heating device that releases a compound by heating rather than burning a material. For example, the material may be tobacco or other non-tobacco products that may or may not contain nicotine. As another example, there are aerosol provision articles, for example, so-called electronic atomizing devices. These electronic atomizing devices typically comprise a liquid aerosol-generating substrate that is heated to vaporize it, thereby producing an inhalable aerosol.

According to the implementation shown in fig. 1, the nebulizer 100 is provided with electrical contacts 11 on the end opposite the power supply mechanism 200 in the length direction, so that when at least a portion of the nebulizer 100 is received in the receiving chamber 27, the electrical contacts 11 come into electrical conduction by coming into contact with the electrical contacts 23.

A seal 26 is provided in the power supply mechanism 200, and at least a part of the internal space of the power supply mechanism 200 is partitioned by the seal 26 to form the above receiving chamber 27. In the embodiment shown in fig. 1, the seal 26 is configured to extend in a cross-sectional direction of the power supply mechanism 200, and optionally is made of a flexible material such as silicone, thereby preventing aerosol-generating substrate of liquid that seeps from the atomizer 100 to the receiving chamber 27 from flowing into the interior of the power supply mechanism 200.

In the implementation shown in fig. 1, the power supply mechanism 200 further includes a battery cell 21 for supplying power; and, a circuit board assembly 30 operable to direct electrical current between the electrical core 21 and the electrical contacts 23.

The embodiment of fig. 2 and 3 shows a schematic structural diagram of one embodiment of the power supply mechanism 200 of fig. 1, including:

The housing 210 is a long cylindrical shape; and in practice, the length of the housing 210 is greater than the width, and the width is greater than the thickness, such that the housing 210 is configured to be flat.

And in some implementations, the length dimension d11 of the housing 210 is between 70-100 mm; and, the width dimension d21 of the housing 210 is between 15 and 25mm; and, the thickness dimension d31 of the housing 210 is between 8 and 15mm.

In some examples, the housing 210 may be formed of a metal or alloy such as stainless steel, aluminum, or the like. Other suitable materials include various plastics (e.g., polycarbonate), metal-plated plastics (metal-plating over plastic), ceramics, and the like.

Housing 210 includes a proximal end 2110 and a distal end 2120 facing away from each other in the length direction; in use, proximal end 2110 is the end for receiving and receiving nebulizer 100, and distal end 2120 is the end for connecting to an external charging device for charging power mechanism 200.

The housing 210 has a front side 2150 and a rear side 2160 facing away from each other in the thickness direction; housing 210 has a surface 2111 at proximal end 2110, surface 2111 being sloped. Specifically, as shown by arrow R1 in fig. 2, surface 2111 is disposed obliquely from front side 2150 to rear side 2160 in the thickness direction. Specifically, the distance d11 of the surface 2111 from the distal end 2120 at the front side 2150 is the length dimension d11 of the housing 210. And, surface 2111 is at a distance d12 from distal end 2120 at rear side 2160 that is less than a length dimension d11 of housing 210; surface 2111 is at a distance d12 of 75-95 mm from distal end 2120 at back side 2160.

The receiving cavity 27 of the power mechanism 200 is open at the proximal end 2110 for receiving the atomizer 100. And, the extension dimension d13 of the receiving chamber 27 in the longitudinal direction of the power supply mechanism 200 is 20 to 30mm.

Housing 210 has an opening 2122 at distal end 2120 for exposing or revealing charging interface 24. And, the housing 210 has a section 2122 near or at the distal end 2120; the width dimension and/or thickness dimension of the section 2122 is tapered in a direction toward the distal end 2120, thereby causing the portion of the housing 210 near the distal end 2120 to be in a tapered or collapsed shape. And in some embodiments, the extension d14 of the section 2122 is between 8 and 20mm.

And further according to fig. 2 and 3, the housing 210 further includes:

a first side 2130 and a second side 2140 facing away in the width direction.

And further according to fig. 2 and 3, the housing 210 is further provided with:

An air inlet 213 for external air to enter the receptacle 27 and further to reenter the nebulizer 100 as the user draws the nebulizer 100, such as shown by arrow R2 in fig. 2 and 3. The air inlets 213 are located or disposed on the first side 2130 and/or the second side 2140. And in the embodiment shown in fig. 3, air inlet 213 is substantially flush with the end of receiving cavity 27 facing away from proximal end 2110, along the width of power mechanism 200.

And, further according to fig. 2 and 3, the housing 210 is further provided with:

An input element 211 for user operation to form an input signal for user operation; the power supply mechanism 200 then selectively switches the power supply mechanism 200 between the locked state and the unlocked state in response to a user input signal. For example, the power mechanism 200 is in a locked state to block power from being output to the atomizer 100 and in an unlocked state to allow power to be output to the atomizer 100.

In some implementations, the input element 211 is selected from a mechanical button, a membrane button, a mechanical switch, a rotary encoder, a dial, a knob, a capacitive touch button, a resistive touch button, a joystick, a slider, a trigger button, a touch screen, and a magnetic switch.

the light source hole 212 is used for allowing the light emitted by the light source 41 to penetrate through the light source hole 212 to the outside of the housing 210 and be received by a user. In some implementations, a user may observe the light emitting state of the light source 41 through the light source aperture 212 to determine the current power of the power mechanism 200.

In some embodiments, the number of light sources 41 is multiple, and the user may be prompted for different amounts of power by activating one or more of the light sources 41 to illuminate. For example, in a specific embodiment, the number of light sources 41 is 4, and are arranged in order along the length direction. In practice, it is possible to inform the user that the current charge is full or sufficient by making 4 of the light sources 41 emit light simultaneously; and, by making only 1 of the light sources 41 emit light, informing the user that the current power is in a low power state, prompting the user to charge. And, only 2 or 3 of the light sources 41 may be simultaneously lighted to prompt the user of the extent of the current electric quantity; for example, 3 of the light sources 41 are simultaneously illuminated to indicate that the current power is below 4 simultaneous illumination and greater than 2 simultaneous illumination, and for example, 2 of the light sources 41 are simultaneously illuminated to indicate that the current power is below 3 simultaneous illumination and greater than only 1 illumination.

In some embodiments, the light source 41 comprises an LED.

And in some embodiments, both the input element 211 and the light source aperture 212 are disposed on the second side 2140. And in some embodiments, the light source aperture 212 is closer to the proximal end 2110 than the input element 211. And, the input element 211 and the light source aperture 212 are shielded from the receiving cavity 27; or the input element 211 and the light source aperture 212 may be closer to the distal end 2120 than the receiving chamber 27.
