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.

[0003] Examples of such products are heating devices that release compounds by heating rather than burning materials. For example, the material may 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). The applicant has proposed an electronic atomizing device with two atomizers arranged opposite each other in Chinese patent CN210581021U. The two atomizers are rotatably arranged within the power supply section of the electronic atomizing device, allowing the user to rotate the intended atomizer towards the proximal end for inhalation via a rotational operation.

[0067] To facilitate understanding of this application, a more detailed description of this application will be provided below in conjunction with the accompanying drawings and specific embodiments.

[0068] This application proposes an electronic atomizing device for atomizing a liquid matrix to generate an aerosol.

[0069] Figures 1 to 8A schematic diagram of an electronic atomizing device according to one embodiment is shown; in this embodiment, the electronic atomizing device includes a first body 100 and a second body 200; the second body 200 is installed within the first body 100.

[0070] In some embodiments, the first body 100 and the second body 200 exist independently of each other before assembly; and after the first body 100 is combined with the second body 200, they together define a complete electronic atomizing device for use or inhalation of aerosol by a user.

[0071] In some embodiments, the second body 200 is an atomizing body for atomizing a liquid matrix to generate an aerosol; the first body 100 is used to mount or hold the second body 200 and is operated by a user to selectively control the atomizer in the second body 200 to generate an aerosol. In some embodiments, the first body 100 and the second body 200 exist before assembly or independently; the second body 200 can generate an aerosol independently for user use or inhalation, while the first body 100 cannot generate an aerosol independently for user use or inhalation.

[0072] In some embodiments, after the first body 100 and the second body 200 are assembled, the second body 200 can be completely removed from or replaced from the first body 100. Alternatively, in other embodiments, after the first body 100 and the second body 200 are assembled, the second body 200 cannot be disassembled from or replaced from the first body 100; and when the liquid matrix within the second body 200 is consumed, it is recycled or discarded as a whole.

[0073] according to Figures 1 to 12 As shown, the first body 100 includes:

[0074] The device comprises a proximal end 110 and a distal end 120 that are opposite to each other in the longitudinal direction; a first side 130 and a second side 140 that are opposite to each other in the width direction; and a front side 150 and a rear side 160 that are opposite to each other in the thickness direction. In use, the proximal end 110 is the end closer to the user for easy suction; the distal end 120 is the end farther from the user. Figures 1 to 12 In some embodiments shown, the first body 100 may be flat. The length dimension of the first body 100 is greater than its width dimension, and the width dimension is greater than its thickness dimension.

[0075] according to Figures 1 to 12 As shown, the first body 100 includes:

[0076] A suction nozzle 20 and a main housing 10 are arranged longitudinally in sequence; the suction nozzle 20 is adjacent to and defines a proximal end 110, and the main housing 10 is adjacent to and defines a distal end 120. In some embodiments, the main housing 10 and / or the suction nozzle 20 may be formed of a metal or alloy such as stainless steel or aluminum; other suitable materials include various plastics, metal-plated plastics, ceramics, etc.

[0077] according to Figures 1 to 12 As shown, the main housing 10 is generally configured as a longitudinally extending frame or truss. A longitudinally extending receiving cavity 11 is formed or defined within the main housing 10; the second body 200 can be received and held within the receiving cavity 11. The receiving cavity 11 extends from the front side 150 to the rear side 160. In an embodiment, the receiving cavity 11 is open at both the front side 150 and the rear side 160.

[0078] according to Figures 1 to 6 As shown, the first body 100 also includes:

[0079] Pins 131 and 141 are used to connect the second body 200 to the main housing 10 of the first body 100. In this embodiment, pins 131 and 141 are arranged along the width direction of the first body 100. Furthermore, pins 131 and 141 are aligned in the width direction. Pin 131 extends from the first side 130 into the receiving cavity 11 and at least partially extends into the second body 200 to connect with it; pin 141 extends from the second side 140 into the receiving cavity 11 and at least partially extends into the second body 200 to connect with it.

[0080] according to Figures 1 to 12 As shown, pins 131 and / or 141 provide a rotatable connection between the second body 200 and the first body 100; furthermore, in this embodiment, the second body 200 is rotatable or flip-around a first axis defined by pins 131 and / or 141 in the width direction of the electronic atomizing device. Alternatively, the second body 200 is rotatable or flip-around a first axis defined by pins 131 and / or 141 in the width direction of the electronic atomizing device. Furthermore, pins 131 and / or 141 are riveted or tightly fitted to the main housing 10 of the first body 100, and pins 131 and / or 141 are not detachable from the main housing 10. Thus, after assembly, pins 131 and / or 141 keep the second body 200 connected to the first body 100, preventing the power supply mechanism of the second body 200 from being detached from the first body 100.

[0081] according to Figures 1 to 12As shown, the user can operate the second body 200 from the front side 150 and / or the rear side 160, for example, by pressing, thereby driving the second body 200 to rotate or flip about a first axis defined by pins 131 and / or 141 in the width direction of the electronic atomizing device, such as... Figure 4 As indicated by the middle arrow P11. Figure 1 or Figure 2 As shown, when the second body 200 rotates to coincide with the longitudinal direction of the first body 100, at least one aerosol outlet of the second body 200 is connected to the air outlet 21 of the mouthpiece 20, thereby defining the usage state of the electronic atomizing device. When the second body 200 rotates to form an inclined angle with the longitudinal direction of the first body 100, the connection between at least one air outlet of the second body 200 and the air outlet 21 of the mouthpiece 20 is disconnected. Furthermore, when the second body 200 rotates to form an inclined angle with the longitudinal direction of the first body 100, as... Figure 4 As shown, the first end 210 and / or the second end 220 of the second body 200 can at least partially extend beyond the front side 150 and / or the rear side 160.

[0082] according to Figures 1 to 14 As shown, the second body 200 includes:

[0083] The first end 210 and the second end 220 are opposite to each other in the longitudinal direction, the first side 230 and the second side 240 are opposite to each other in the width direction, and the front side 250 and the rear side 260 are opposite to each other in the thickness direction.

[0084] The outer casing defines the outer surface of the second body 200; the outer casing has a first side 230 defining a plug hole 2311 for a pin 131 to be inserted and connected, and a second side 240 defining a plug hole 2411 for a pin 141 to be inserted and connected.

[0085] When the second body 200 is installed or housed in the receiving cavity 11 of the first body 100, the pin 131 of the first body 100 is inserted into the insertion hole 2311 and the pin 141 is inserted into the insertion hole 2411, thereby establishing a rotational connection between the second body 200 and the first body 100.

[0086] In this embodiment, the electronic atomizing device further includes:

[0087] The first limiting mechanism provides a limiting and / or positioning between the second body 200 and the first body 100 when the second body 200 rotates to a first orientation and / or a second orientation that coincides with the longitudinal direction of the first body 100, thereby keeping the second body 200 in a first orientation and / or a second orientation that coincides with the longitudinal direction of the first body 100.

[0088] according to Figures 1 to 14In the illustrated embodiment, the first limiting mechanism includes:

[0089] At least one or more limiting protrusions and at least one or more limiting grooves adapted to the limiting protrusions, and their cooperation is used to provide limiting during rotation of the second body 200.

[0090] In some embodiments, a limiting protrusion is formed or disposed on one of the first body 100 and the second body 200, and a limiting groove is formed or disposed on the other of them.

[0091] exist Figures 1 to 14 In the specific embodiment shown, the limiting protrusion includes at least one or more first limiting ridges 1311 formed or arranged on the pin 131, and at least one or more first limiting ridges 1411 formed or arranged on the pin 141; the first limiting ridges 1311 and 1411 extend along a first axis in the width direction of the electronic atomizing device. Furthermore, a plurality of first limiting ridges 1311 and / or a plurality of first limiting ridges 1411 are arranged around the first axis in the width direction of the electronic atomizing device. Figures 1 to 14 In the specific embodiment shown, the limiting groove includes at least two or more first limiting grooves 2314 formed or arranged on the inner surface of the insertion hole 2311, and at least two or more first limiting grooves 2414 formed or arranged on the insertion hole 2411. The first limiting grooves 2314 and / or the first limiting grooves 2414 are arranged to extend along a first axis in the width direction of the electronic atomizing device.

[0092] In use, when the second body 200 is rotated or flipped to a predetermined orientation, the limiting protrusion extends into the limiting groove to form a fit to provide a limit when the second body 200 is rotated or flipped to a predetermined orientation.

[0093] In some embodiments, the predetermined orientation includes at least a first orientation in which the longitudinal direction of the second body 200 coincides with the longitudinal direction of the first body 100 and the first end 210 faces the proximal end 110, and a second orientation in which the longitudinal direction of the second body 200 coincides with the longitudinal direction of the first body 100 and the first end 210 faces the distal end 120.

[0094] Alternatively, in some other embodiments, the predetermined orientation may further include a third orientation in which the longitudinal direction of the second body 200 has a predetermined tilt angle with the longitudinal direction of the first body 100. In some embodiments, the predetermined tilt angle is, for example, 30°, 45°, 60°, 75°, 90°, 120°, or 150°, which is advantageous for providing limitation at more positions during the rotation of the second body 200.

[0095] In some embodiments, the first limiting ridge 1311 and / or the first limiting ridge 1411 of the limiting protrusion have a protrusion height of approximately 0.2 mm to 2.0 mm; and the first limiting groove 2314 and / or the first limiting groove 2414 of the limiting groove have a recess depth of approximately 0.2 mm to 2.0 mm. In some embodiments, the surface of the first limiting ridge 1311 and / or the first limiting ridge 1411 of the limiting protrusion is a smooth arcuate surface.

[0096] Alternatively, in some other variations, the first limiting mechanism may further include magnetic elements for providing retention by magnetic attraction when the second body 200 rotates to the first and / or second orientation. For example, the magnetic elements may include a first magnetic element disposed on pins 131 and / or 141, and a second magnetic element disposed on the second body 200. The second magnetic element is disposed near or adjacent to the insertion holes 2311 and / or 2411. Limitation and retention are provided by the magnetic attraction of the first and second magnetic elements when the second body 200 rotates to the first and / or second orientation.

[0097] according to Figures 1 to 12 In the illustrated embodiment, the first body 100 further includes:

[0098] At least two or more connecting ports, such as a first connecting port 31 and a second connecting port 32, are arranged or defined on the inner surface of the receiving cavity 11 near or toward the proximal end 110. When the second body 200 is rotated to coincide with the longitudinal direction of the first body 100, the first connecting port 31 and the second connecting port 32 are aligned with and connected to the aerosol output port of the second body 200, thereby enabling the output of aerosols generated by the second body 200.

[0099] according to Figures 1 to 12 In the illustrated embodiment, the first connection port 31 and the second connection port 32 are defined by a flexible sealing element 30. The first body 100 also includes:

[0100] A flexible sealing element 30 is at least partially housed or arranged between the nozzle 20 and the main housing 10 to provide a seal between them.

[0101] In one embodiment, the sealing element 30 has a first flange 33 extending through a first mounting hole 12 of the main housing 10 into a receiving cavity 11, and a second flange 34 extending through a second mounting hole 13 of the main housing 10 into a receiving cavity 11. The first flange 33 surrounds and defines a first communication port 31, and the second flange 34 surrounds and defines a second communication port 32.

[0102] In this embodiment, when the second body 200 rotates to a first orientation within the receiving cavity 11 of the first body 100, the first connecting port 31 aligns with and communicates with the first aerosol output port 2111 of the first end 210 of the second body 200, and the second connecting port 32 aligns with and communicates with the first aerosol output port 2112 of the first end 210 of the second body 200. When the second body 200 rotates to a second orientation within the receiving cavity 11 of the first body 100, the first connecting port 31 aligns with and communicates with the second aerosol output port 2211 of the second end 220 of the second body 200, and the second connecting port 32 aligns with and communicates with the second aerosol output port 2212 of the second end 220 of the second body 200.

[0103] In one embodiment, at least a portion of the first flange 33 and / or the second flange 34 protrudes from the inner surface of the receiving cavity 11 near or toward the proximal end 110. When the second body 200 rotates within the receiving cavity 11 of the first body 100 to a first orientation, at least a portion of the first flange 33 and the second flange 34 abuts against and is at least partially pressed or compressed by the second body 200, thereby providing flexible damping and / or a seal between them. When the second body 200 rotates within the receiving cavity 11 of the first body 100 to a second orientation, at least a portion of the first flange 33 and the second flange 34 abuts against and is at least partially pressed or compressed by the second body 200, thereby providing flexible damping and / or a seal between them.

[0104] according to Figures 1 to 12 As shown, the main housing 10 has a mounting groove 16 arranged towards the proximal end 110 for partially accommodating and retaining the sealing element 30. An annular flange 15 is arranged within the mounting groove 16, surrounding and defining a nozzle connection hole. This nozzle connection hole extends from the mounting groove 16 into the receiving cavity 11. A pin 23 is arranged on the nozzle 20, passing through the nozzle connection hole defined by the flange 15, and connecting it to the main housing 10 within the receiving cavity 11 to prevent separation of the nozzle 20 from the main housing 10. In an embodiment, at least one barb is arranged on the pin 23; the barb on the pin 23 then connects to the main housing 10 to prevent separation of the nozzle 20 from the main housing 10.

[0105] according to Figures 1 to 12 As shown, the suction nozzle 20 can be operated by the user, thereby rotating about the pin 23 relative to the main housing 10 between a first position and a second position, as... Figure 5 As indicated by the middle arrow P12. Alternatively, the nozzle 20 can rotate about a second axis defined by the pin 23 along the longitudinal direction of the electronic atomizing device. For example, in Figure 6 and Figure 8 In the middle, the suction nozzle 20 is rotated to the first position. For example, in Figures 1 to 4 , Figure 7 In this embodiment, the suction nozzle 20 is rotated to a second position; in the first position, the suction nozzle 20 is relatively closer to the first side 130; in the second position, the suction nozzle 20 is relatively closer to the second side 140. Alternatively, in the first position, the distance between the suction nozzle 20 and the second side 140 is greater than the distance between the suction nozzle 20 and the first side 130; and in the second position, the distance between the suction nozzle 20 and the second side 140 is less than the distance between the suction nozzle 20 and the first side 130.

[0106] In this embodiment, the suction nozzle 20 is arranged off-center from the longitudinal central axis of the main housing 10 / first body 100.

[0107] according to Figures 1 to 12 As shown, the suction nozzle 20 also includes:

[0108] A connecting channel 22 extends from the air outlet 21 toward the distal end 120. In the first position, the nozzle 20 has a first connecting port 31 connected to the air outlet 21 via the connecting channel 22 within the nozzle 20, and a second connecting port 32 is closed by the nozzle 20.
