Description

Technical Field

[0001] The present disclosure generally relates to a vaporization device, and more particularly to an electronic device for providing an inhalable aerosol. Background Art

[0002] An electronic cigarette is an electronic product that heats and atomizes a vaporizable solution and produces aerosol for users to inhale. In recent years, major manufacturers have begun to produce a variety of electronic cigarette products. Generally speaking, an electronic cigarette product includes a shell, an oil storage chamber, an atomization chamber, a heating component, an air inlet, an air flow channel, an air outlet, a power supply device, a sensing device, and a control device. The oil storage chamber is used to store a vaporizable solution, and the heating component is used to heat and atomize the vaporizable solution and produce aerosol. The air inlet and the atomization chamber are connected to each other, and air is provided to the heating component when the user inhales. The aerosol generated by the heating component is first generated in the atomization chamber, and then inhaled by the user through the air flow channel and the air outlet. The power supply device provides the power required by the heating component, and the control device controls the heating time of the heating component according to the user's inhalation action detected by the sensing device. The shell covers each of the above components.

[0003] When users use electronic cigarettes, the generated aerosol may condense into liquid in various cavities or channels. For example, the aerosol may condense into liquid in cavities or channels such as the atomization chamber, the air inlet, the air flow channel, or the air outlet. The liquid in such cavities or channels may leak during the user's use of the electronic cigarette, contaminating the user's clothes, pants or other valuables carried with them, thereby causing a poor user experience. With the increasing frequency of use, how to make electronic cigarettes better meet the needs of users through various improvements and thus improve the user experience is an indispensable part of the development of electronic cigarettes.

[0004] Therefore, an atomizing device is proposed to solve the above problems. Summary of the invention

[0005] Some embodiments of the present application provide an atomizing device. The proposed atomizing device includes a housing, a top cover, and a heating component. The housing and the top cover define a storage compartment, and the top cover surrounds the heating component.

[0006] Some embodiments of the present application provide an atomization device. The proposed atomization device includes a housing, a heating component, and a top cover. The top cover is connected to the housing and the heating component. BRIEF DESCRIPTION OF THE DRAWINGS

When the user uses the atomizer, the atomized smoke oil mixes with the low-temperature air, which may cause the atomized smoke oil to condense. The condensed smoke oil can be absorbed by the oil absorption pad 151 to prevent the smoke oil from overflowing outside the cigarette cartridge 1. However, the condensed smoke oil may not be completely absorbed by the oil absorption pad 151, and may overflow outside the cigarette cartridge 1 through the tube 17.

[0074] The opening 761 is exposed to the heating base 74 (eg Figure 8 The opening 762 is close to the heating assembly 73. The heating base 74 and the heating assembly 73 define an atomization chamber 75. The lower portion of the heating assembly 73 is exposed to the atomization chamber 75. The aerosol generated by the heating assembly 73 is formed in the atomization chamber 75. The aerosol generated by the heating assembly 73 is inhaled by the user through the tube channel 711. The channel 711 is fluidly connected to the atomization chamber 75. The groove 7221 (as shown in FIG. 222 ) is formed in the atomization chamber 75. Fig. 9 As shown) is fluidly connected to the atomization chamber 75.

[0075] Fig.10The dotted arrow in the figure shows the air outlet channel P2 of the cartridge 7. External fluid (such as air) flows in from the opening 761 of the tube 76, passes through the tube 76, and flows out from the opening 762 of the tube 76. The air flowing out from the opening 762 of the tube 76 flows into the atomization chamber 75 at the bottom of the heating component 73, and the aerosol generated by the heating component 73 mixes with the air, and then is inhaled by the user through the channel 711 of the shell 71. When the user inhales, the air passes through the atomization chamber 75 at the bottom of the heating component 73, and the atomized oil mixes with the cold air, which may cause the atomized oil to condense and overflow outside the cartridge 7. The condensed oil may also overflow outside the cartridge 1 through the tube 76.

Fig.11 The multiple dotted arrows in the figure show the air outlet channel P2 of the cigarette cartridge 7. External fluid (such as air) flows in from the opening 761 of the tube 76, passes through the tube 76, and flows out from the opening 762 of the tube 76. The air flowing out from the opening 762 of the tube 76 flows into the atomization chamber 75 at the lower part of the heating component 73, and the aerosol generated by the heating component 73 mixes with the air, then passes through the groove 7221, through the openings 7222 and 7212, and through the channel 711 of the shell 71 to be inhaled by the user. Fig.10 and Fig.11 The passage P2 shown does not pass through the space 732, the opening 7226, and the opening 7231. When the user inhales, the air passes through the atomization chamber 75 at the bottom of the heating assembly 73, and the heated and atomized tobacco oil mixes with the air, which may cause the atomized tobacco oil to condense and overflow outside the cigarette cartridge 7. The condensed tobacco oil may also overflow outside the cigarette cartridge 1 through the tube 76.
