[0080] One embodiment of the present application provides an electronic atomization device, which can be found in Figure 1 As shown, the invention comprises a nebulizer 100 storing a liquid matrix and vaporizing it to generate an aerosol, and a power supply mechanism 200 for supplying power to the nebulizer 100. Figure 1 In the illustrated embodiment, the atomizer 100 and the power supply mechanism 200 of the electronic atomization device can be separated or disassembled relative to each other; the electronic atomization device having such atomizer 100 and the power supply mechanism 200 can be separated or disassembled relative to each other, such as the so-called "replaceable cartridge" electronic atomization device. Or in some other variant embodiments, the atomizer 100 and the power supply mechanism 200 of the electronic atomization device are tightly wrapped and fixed by the shell component of the electronic atomization device, so that the atomizer 100 and the power supply mechanism 200 cannot be detachable relative to each other from the inside of the shell component; the electronic atomization device having such atomizer 100 and the power supply mechanism 200 cannot be detachable relative to each other, such as the so-called "integrated or disposable" electronic atomization device.

[0081] In an alternative embodiment, for example Figure 1 As shown, the power supply mechanism 200 includes a receiving cavity 270 arranged at one end along the length direction for receiving and accommodating at least a portion of the atomizer 100, and an electrical contact 230 at least partially exposed on the surface of the receiving cavity 270, for supplying power to the atomizer 100 when at least a portion of the atomizer 100 is received and accommodated in the power supply mechanism 200.

[0082] according to Figure 1 In the exemplary embodiment shown, an electric contact 21 is provided on the end of the atomizer 100 opposite to the power supply mechanism 200 along the length direction, so that when at least a portion of the atomizer 100 is received in the receiving cavity 270, the electric contact 21 contacts and abuts against the electric contact 230 to form conductivity.

[0083] A sealing member 260 is disposed in the power supply mechanism 200, and the sealing member 260 separates at least a portion of the internal space of the power supply mechanism 200 to form the above receiving cavity 270. Figure 1In the exemplary embodiment shown, the seal 260 is configured to extend along the cross-sectional direction of the power mechanism 200, and is preferably made of a flexible material, thereby preventing the liquid matrix that seeps from the atomizer 100 into the receiving chamber 270 from flowing to the controller 220, sensor 250 and other components inside the power mechanism 200.

[0084] exist Figure 1 In the exemplary embodiment shown, the power supply mechanism 200 also includes a battery cell 210 for supplying power at the other end away from the receiving cavity 270 along the length direction; and a controller 220 arranged between the battery cell 210 and the receiving cavity, which can be operated to guide current between the battery cell 210 and the electrical contact 230.

[0085] During use, the power supply mechanism 200 includes a sensor 250 for sensing the suction airflow generated when the atomizer 100 is inhaled, and then the controller 220 controls the battery cell 210 to output current to the atomizer 100 according to the detection signal of the sensor 250 .

[0086] exist Figure 1 In the exemplary embodiment shown, the power supply mechanism 200 is provided with a charging interface 240 at the other end away from the receiving cavity 270 for charging the battery cell 210 .

[0087] according to Figures 2 to 9 As shown, in one embodiment, the atomizer 100 includes:

[0088] In some embodiments, the housing 10 may be a transparent structure, and the atomizer 100 further includes a color-recognizable identification structure, which is disposed on the inner surface of the housing 10 and is visible through the transparent housing 10. The color-recognizable identification structure is used to provide a visual indication associated with a unique property of the atomizer 100, so that a user can observe or receive the color of the color-recognizable identification structure through the transparent housing 10 to obtain information about the unique property of the atomizer 100.

[0089] In some embodiments, the identification structure of the identifiable color can be a color pattern formed or sprayed or combined on the inner surface of the housing 10, or a groove structure with a color, or an identification element, etc., so as to realize the provision of functions associated with the unique properties of the atomizer 100. In some embodiments, the identification structure of the identifiable color can be made of food-grade hardware plastic or silicone and other materials, and can be used to mark the flavor of the atomizer 100 to simplify the manufacturing process of the atomizer 100 and reduce the manufacturing cost of the atomizer. In some representative embodiments, the identification structure of the identifiable color is presented in the form of a color pattern, and the pattern can be integrated or combined with the product LOGO to present it as a whole.

[0090] In some specific implementations, the unique properties of the above atomizer 100 may include the flavor of the flavor contained in the liquid matrix, such as peach flavor, mint flavor, and orange flavor. For example, in some specific implementations, the identification structure with a recognizable color has a color associated with the flavor of the flavor contained in the liquid matrix, for example, the identification structure with a recognizable color has a yellow color that identifies or indicates a liquid matrix containing orange flavor, or the identification structure with a recognizable color has a green color that identifies or indicates a liquid matrix containing mint flavor, etc., to respectively identify or indicate the flavor of the flavor contained in the liquid matrix.

[0091] For example, in some specific implementations, the above unique properties may include the strength of nicotine contained in the liquid matrix, such as the nicotine content.

[0092] For another example, in some specific implementations, the above unique properties may include a maximum capacity of the liquid storage chamber 112 in the nebulizer 100, such as 2 mL / 3 mL.

[0093] For example, in some specific implementations, the above unique properties may include an optimal vaporization power or vaporization temperature of the liquid matrix in the atomizer 100 .

[0094] For another example, in some specific implementations, the above unique properties may include at least one of the viscosity, specific heat, boiling point, or vaporization efficiency of the liquid matrix in the atomizer 100 .

For example, in some implementations, the housing 10 is transparent; and the identification structure of the identifiable color has at least one color of yellow, green, red or blue, purple, etc.

[0096] It is understandable that the specific connection method between the identification structure of the identifiable color and the shell 10 is not limited in the present embodiment, and may be, for example, a fixed connection method such as integral molding or welding, or one of a variety of detachable connection methods such as screw connection or magnetic attraction. It should be noted that when the internal components of the atomizer 100 are adjusted, compared with the prior art method of printing the identification structure of the identifiable color on the shell, the identification structure of the identifiable color can also be detachably replaced to avoid re-manufacturing the shell, thereby reducing the manufacturing cost of the atomizer 100.
