Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and more particularly to an electronic atomization device. 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.

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). Chinese patent CN221128829U proposes in a known electronic atomizing device that a porous body is arranged at an angle, and a heating element is arranged on the angled atomizing surface of the porous body to heat the liquid matrix within the porous body to generate an aerosol; in the airflow design, air is longitudinally directed from a distal air inlet toward the angled atomizing surface towards the heating element to carry the aerosol generated by the atomizing surface outwards.

[0116] According to the suction Figures 1 to 7 As shown by the middle arrow R2, the air entering from the air inlet 131 passes through the air hole 61 on the wrapping element 60 and the notch 521 of the absorption element 52 in sequence before entering the gap 57; then it passes through the air inlet connecting hole 53 and enters the atomizing chamber 156, and carries the aerosol from the output channel 155 to the air outlet 111.

[0117] according to Figure 5 As shown, output channel 155 is arranged to extend longitudinally. Figures 3 to 7 As shown, the output channel 155 has a flat shape. Specifically, the longitudinal length of the output channel 155 is greater than its width d155, and the width d155 is greater than its thickness. And according to... Figure 5 As shown, the width dimension d155 of the output channel 155 is variable. Figure 5 In the embodiment shown, the width dimension d155 of the output channel 155 gradually decreases along the direction close to the proximal end 110.

[0118] In some embodiments, the central axis of the air intake port 53 is arranged obliquely relative to the longitudinal direction of the electronic atomizing device. Specifically, the air intake port 53 has a first inner surface 531 and a second inner surface 532; the first inner surface 531 and the second inner surface 532 are parallel. The first inner surface 531 and / or the second inner surface 532 are arranged obliquely relative to the longitudinal direction of the electronic atomizing device. The angle of inclination of the first inner surface 531 and / or the second inner surface 532 relative to the longitudinal direction of the electronic atomizing device is approximately 25° to 65°.

[0119] In an embodiment, the distance between the first inner surface 531 and the second inner surface 532 is approximately between 2 and 5 mm.

[0120] In this embodiment, the first inner surface 531 and the second surface 312 of the porous body 31 are substantially parallel. Furthermore, the first inner surface 531 and the heating element 32 are arranged in parallel.

[0121] During suction, when air enters the atomizing chamber 156 through the air inlet 53, it enters the atomizing chamber 156 along a path or angle parallel to the second surface 312 of the porous body 31 and flows through the second surface 312 of the porous body 31, thereby carrying away aerosols as completely as possible and reducing the generation of condensate.

[0122] according to Figure 7 As shown, a portion of the second surface 312 of the porous body 31 in the longitudinal direction of the electronic atomizing device is opposite or aligned with the air outlet port of the air inlet communication port 53, while another portion is offset from the air outlet port of the air inlet communication port 53. Alternatively, a portion of the second surface 312 of the porous body 31 in the longitudinal direction of the electronic atomizing device projects onto a portion of the port of the air inlet communication port 53. In the longitudinal direction of the electronic atomizing device, the porous body element 31 and the air inlet communication port 53 are spaced apart. In the longitudinal direction of the electronic atomizing device, there is a distance d11 between the porous body element 31 and the air inlet communication port 53. In some embodiments, the distance d11 between the porous body element 31 and the air inlet communication port 53 is between 1 and 8 mm. In some more preferred embodiments, the distance d11 between the porous body element 31 and the air inlet communication port 53 is between 2 and 5 mm; for example, in one specific embodiment, the distance d11 between the porous body element 31 and the air inlet communication port 53 is 3.23 mm.

[0123] It should be noted that the preferred embodiments of this application are given in the specification and accompanying drawings, but are not limited to the embodiments described in this specification. Furthermore, those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
