Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an atomizer and an atomizing body for the atomizer. Background Technology

[0002] Tobacco products (such as cigarettes, cigars, etc.) produce tobacco smoke by burning tobacco during use. Efforts are being made to replace these tobacco-burning products by creating products that release compounds without combustion.

[0003] Examples of such products are heating devices that release compounds by heating rather than burning materials. For example, the material could be tobacco or other non-tobacco products, which may or may not contain nicotine. As another example, aerosol-providing articles exist, such as so-called electronic atomizing devices. These devices typically contain a liquid that is heated to vaporize, thereby producing an inhalable aerosol. The liquid may contain nicotine and / or flavorings and / or aerosol-generating substances (e.g., glycerin). Known electronic atomizing devices replenish a liquid matrix to a reusable atomizing body via a separate, replaceable liquid source; when the liquid source is attached to the atomizing body, a liquid transfer channel is established between them, thereby replenishing the atomizing body with the liquid matrix from the liquid source. The liquid source is equipped with a movable valve. When the liquid source is connected to the atomizing body, the magnetic core formed between the liquid source and the atomizing body repels the valve to move to the open position, thereby opening and connecting the liquid transmission channel. When the liquid source is separated from the atomizing body, the valve can be reset to the closed position to close the liquid transmission channel and prevent the liquid matrix from leaking.

[0048] One embodiment of this application provides an electronic atomizing device, which can be found in [reference needed]. Figure 1 As shown, it includes an atomizer 100 that stores a liquid matrix and atomizes it to generate an aerosol, and a power supply mechanism 200 that supplies power to the atomizer 100. Figure 1In the illustrated embodiment, the atomizer 100 and power supply mechanism 200 of the electronic atomizing device are detachable from each other; electronic atomizing devices with such detachable atomizer 100 and power supply mechanism 200 are, for example, so-called "refillable" electronic atomizing devices. Alternatively, in some further variations, the atomizer 100 and power supply mechanism 200 of the electronic atomizing device are securely enclosed and fixed by a housing component of the electronic atomizing device, thereby preventing the atomizer 100 and power supply mechanism 200 from being detachable from each other within the housing component. Electronic atomizing devices with such non-detachable atomizer 100 and power supply mechanism 200 are, for example, so-called "integrated or disposable" electronic atomizing devices.

[0049] One embodiment of this application provides an electronic atomizing device, which can be found in [reference needed]. Figure 1 As shown, it includes an atomizer 100 that stores a liquid matrix and atomizes it to generate an aerosol, and a power supply mechanism 200 that supplies power to the atomizer 100.

[0050] In an alternative embodiment, for example Figure 1 As shown, the power supply mechanism 200 includes a receiving cavity 270 disposed 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 within the receiving cavity 270 for electrically connecting with the atomizer 100 when at least a portion of the atomizer 100 is received and accommodated within the power supply mechanism 200, thereby supplying power to the atomizer 100.

[0051] according to Figure 1 In the embodiment shown, an electrical contact 21 is provided on the end of the atomizer 100 opposite to the power supply mechanism 200 along the length direction. When at least a portion of the atomizer 100 is received in the receiving cavity 270, the electrical contact 21 forms an electrical conductivity by contacting and abutting against the electrical contact 230.

[0052] A sealing element 260 is provided inside the power supply mechanism 200, and the sealing element 260 divides at least a portion of the internal space of the power supply mechanism 200 to form the receiving cavity 270. Figure 1 In the illustrated embodiment, the seal 260 is configured to extend in a longitudinal direction perpendicular to the power supply mechanism 200, and is preferably made of a flexible material such as silicone, thereby preventing the liquid matrix that seeps from the atomizer 100 into the receiving cavity 270 from flowing into components such as the controller 220 and sensor 250 inside the power supply mechanism 200.

[0053] exist Figure 1In the illustrated embodiment, the power supply mechanism 200 further includes a battery cell 210 for power supply located at the other end of the receiving cavity 270 along its length; and a controller 220 disposed between the battery cell 210 and the receiving cavity 270, the controller 220 being operable to guide current between the battery cell 210 and the electrical contact 230.

During removal or detachment, an elastic force is provided by the elastic element 334 to drive the valve core 331 from the open position to the closed position.
