Detailed Description

To facilitate an understanding of the present application, the present application is described in more detail below with reference to the following figures and detailed description.

As shown in fig. 1-4, an embodiment of the present application provides an aerosol-generating system comprising a charging device 100 and an aerosol-generating device 200.

As shown in fig. 5 to 6, the charging device 100 includes a main housing 101, a sub-housing 102, a bottom cover 103, a battery cell 104, a circuit board 105, and a fixing member 106.

The main casing 101 has a notch 101c, and the notch 101c is disposed on one of the side walls of the main casing 101 in the width direction, for example, the right side wall. The notch 101c has an arc shape curved in a direction approaching the bottom wall of the main casing 101. The top wall of the main housing 101 has an opening 101d, and the opening 101d communicates with the notch 101 c. The sub-housing 102 is fitted at the notch 101 c; when assembled, a portion of the secondary housing 102 covers the notch 101c, and another portion of the secondary housing 102 covers the opening 101d. Part of the outer surface of the secondary housing 102 defines a receiving cavity B1 with an opening, and at least part of the aerosol-generating device 200 can be received in the receiving cavity B1.

As will be understood in conjunction with fig. 7, the inner surface of the left side wall of the main housing 101 has a female buckle 101a, and the left end of the secondary housing 102 has a male buckle 102a; when the secondary housing 102 is assembled at the notch 101c, the female buckle 101a and the male buckle 102a cooperate to realize a snap connection, so as to limit the secondary housing 102 from moving upward (toward the top wall of the primary housing 101) and separating from the primary housing 101.

As will be understood in conjunction with fig. 8, the inner surfaces of the front and rear side walls (i.e., the two side walls opposite to each other in the thickness direction) of the main housing 101 further have a female buckle 101b, and the sub housing 102 has a male buckle 102b; when the secondary housing 102 is assembled in the notch 101c, the female buckle 101b and the male buckle 102b are matched to realize a snap connection, so that the secondary housing 102 can be limited to move back and forth and left and right along the horizontal direction to be separated from the primary housing 101.

As shown in fig. 9-10, in a preferred implementation, the female buckle 101b includes a first baffle 101b1, a second baffle 101b2, and a third baffle 101b3; the first baffle 101b1 and the second baffle 101b2 are arranged at intervals and extend in the longitudinal direction; the third baffle 101b3 extends from the first baffle 101b1 toward the second baffle 101b2 while maintaining a space from the second baffle 101b 2. The male buckle 102b has a substantially L-shaped cross section, and includes a base plate extending in the thickness direction and an extension plate extending in the width direction from the base plate. The sub-housing 102 may be provided with a plurality of male buckles 102b, the plurality of male buckles 102b being arranged at intervals in the longitudinal direction. During assembly, the extension plate near the male buckle 102b at the lower end of the secondary housing 102 is placed in the female buckle 101b (i.e., in the structure formed by the inner surfaces of the front and rear side walls of the main housing 101, the first baffle 101b1, the second baffle 101b2, and the third baffle 101b 3), the substrate thereof is clamped between the third baffle 101b3 and the second baffle 101b2, and then the secondary housing 102 is pushed down along the gap between the third baffle 101b3 and the second baffle 101b2 until the male buckle 102a is buckled in the female buckle 101a or the secondary housing 102 is completely assembled to the notch 101c of the main housing 101. After assembly, the first shutter 101b1, the second shutter 101b2, and the third shutter 101b3 can restrict the L-shaped pin 102b from moving in a direction perpendicular to the assembly direction, that is, in a horizontal direction, back and forth and left and right.

It should be noted that the longitudinal direction, the thickness direction, the width direction, and the horizontal direction may be defined with reference to the charging device 100 shown in fig. 5, for example.

The snap connection may be, for example: the positions of the female buckle 101a and the male buckle 102a, and the female buckle 101b and the male buckle 102b are interchangeable. For example: the female buckle 101b is provided on the sub-housing 102, and the male buckle 102b is provided on the main housing 101. The female snap 101a or the female snap 101b may be configured as a groove, a hole, or the like.

The bottom wall of the main housing 101 has a through hole 101e, the sub-housing 102 further has a fixing hole 102c corresponding to the through hole 101e, and the fixing member 106 is fixed in the fixing hole 102c after passing through the through hole 101 e. Thus, the main housing 101 and the sub-housing 102 are fixedly coupled by the fixing member 106. The fasteners 106 may be screws, pins, or the like.

The bottom cover 103 is assembled on the bottom wall of the main housing 101, and the bottom cover 103 can completely shield the fixing member 106 exposed on the bottom wall of the main housing 101, thereby achieving the aesthetic effect. In a preferred embodiment, the bottom cover 103 and the main housing 101 may be connected by a snap connection, for example: a male buckle is arranged on the main shell 101, and a female buckle matched with the male buckle is arranged on the bottom cover 103; the structure of the male and female fasteners is not limited, and reference can be made to the above.

The battery cell 104 is used for providing power. In a preferred implementation, the battery cell 104 is a rechargeable battery cell, and the battery cell 104 can be charged through the charging port B2. The battery cell 104 is fixed in the main casing 101.

The wiring board 105 is used for control of the charging device 100. The circuit board 105 may be fixed to the sub-housing 102 by a connector (not shown), and the circuit board 105 is fitted into the main housing 101 when the sub-housing 102 is fitted at the notch 101 c. The circuit board 105 integrates various components such as a single chip microcomputer, a charge control chip, and the like. The charging device 100 further includes an electrical connection terminal B3, one end of the electrical connection terminal B3 is electrically connected to the circuit board 105 or the battery cell 104, and the other end of the electrical connection terminal B3 is exposed in the accommodating cavity B1 after passing through the sub-housing 102.

As shown in fig. 11-12, an aerosol-generating device 200 for heating an aerosol-forming substrate in an aerosol-generating article 300 for atomisation to generate an aerosol comprises a first portion 21, and a second portion 22 removably connected to the first portion 21.

The first part 21 comprises a cavity 210 having an opening through which at least part of the second part 22 is received within the cavity 210 when the second part 22 is connected to the first part 21. Disposed within the chamber 210 is a heating element 211, the heating element 211 being in the form of a needle or pin, the heating element 211 being configured to be insertable into an aerosol-forming substrate of an aerosol-generating article 300 to heat it.

The first portion 21 is provided with a notch 212 communicating with the opening of the chamber 210, and the second portion 22 can open or close the notch 212 by an operation of removably connecting or removing the first portion 21. The notch 212 is disposed on one of the side walls of the first portion 21 in the width direction, for example, the right side wall. The notch 212 has an arc shape curved in a direction approaching the key A4. The user may thus reach into the chamber 210 through the gap 212 to clean the heating element 211.

The heating element 211 comprises a resistive heating element, for example, the heating element 211 may comprise an electrically conductive trace, and the heating element 211 may be heated when an electrical current flows through the electrically conductive trace. The heating element 211 may be connected to the cell 213 within the first portion 21 by means of a lead, pin, electrical terminal, etc. to generate heat to heat the aerosol-generating article 300 under power supplied by the cell 213. The cell 213 is disposed between the bottom wall of the chamber 210 and the bottom wall of the first portion 21. The battery cell 213 is a rechargeable battery cell, and the battery cell 213 can be charged through the charging port A3.

A circuit board 214 is also provided between the bottom wall of the chamber 210 and the bottom wall of the first section 21. The circuit board 214 is used for control of the aerosol-generating device 200. The circuit board 214 integrates various components such as a single chip microcomputer, a charging control chip, a key switch, and the like. The aerosol-generating device 200 may be operated by means of a key A4, for example: activating the heating element 211 to begin heating, etc.

The aerosol-generating device 200 further comprises an electrical connection terminal A2, one end of the electrical connection terminal A2 is electrically connected to the battery cell 213 or the circuit board 214 or another circuit board, and the other end of the electrical connection terminal A2 is exposed on the housing of the first portion 21: specifically, the housing of the first portion 21 is provided with a through hole in which the other end of the electrical connection terminal A2 is exposed. When the aerosol-generating device 200 is combined with the charging device 100, the electrical connection terminal A2 is kept in contact with the electrical connection terminal B3 to form an electrical connection; at this point, the charging device 100 may provide power to the aerosol-generating device 200. Generally, the capacity of the battery cell 104 is larger than that of the battery cell 213; therefore, the charging device 100 can directly charge the battery cell 213. When the heating element 211 is operated, the charging device 100 may supply power to the heating element 211 while charging the battery cells 213.

The second part 22 is provided with an insertion opening A1; when the second part 22 is connected to the first part 21, the aerosol-generating article 300 may be removably received within the chamber 210 through the insertion opening A1. Meanwhile, a slide cover 221 for opening or closing the aerosol-generating article 300 is provided on the second part 22, the slide cover 221 being movably provided on the second part 22 and having a first position and a second position opposite to the second part 22; the slide cover 221 opens the insertion opening A1 at the first position, and blocks or closes the insertion opening A1 at the second position.

Based on the usage requirements that promote ease of operation of receiving and removing the aerosol-generating article 300, the second part 22 is also provided with a cylindrical extractor 223 in spatial communication with the insertion opening A1, the extractor 223 is inserted or received within the chamber 210 of the first part 21 when the second part 22 is connected to the first part 21, and the space inside the extractor 223 forms a holding space for holding the aerosol-generating article 300. The heating element 211 heats by penetrating into the aerosol-generating article 300 held within the extractor 223. The retained state of the aerosol-generating article 300 within the extractor 223 is maintained when the second portion 22 is removed from separation from the first portion 21.

In the foregoing example, the aerosol-generating device 200 is an electrically heated smoking device that heats a solid aerosol-forming substrate, and the heating element 211 is of a resistive heating type. In other examples, the heating manner of the heating element 211 is not limited to resistance heating, but may be infrared heating, electromagnetic heating, air heating, or the like; nor is it limited to the heating means inserted into the aerosol-generating article 300 but may also be heating means surrounding at least part of the aerosol-generating article 300, so-called circumferential heating or peripheral heating. In other examples, the aerosol-generating device 200 may also be a device that atomizes a liquid aerosol-forming substrate, may be heat nebulization, may also be ultrasonic nebulization, or the like.

As will be appreciated in conjunction with fig. 13-14, the aerosol-generating device 200 also includes a first magnetic element 215 and a second magnetic element 222. The first magnetic element 215 and the second magnetic element 222 are both square; preferably made of permanent magnetic materials, such as magnets, ru Tiepeng, and the like. The first magnetic element 215 is disposed within the first portion 21 (between the bottom wall of the chamber 210 and the bottom wall of the first portion 21) and is disposed proximate to the bottom wall of the chamber 210. A second magnetic element 222 is disposed within the second portion 22; specifically, the second magnetic element 222 is located on one side of the extractor 223 and is disposed proximate to the bottom end of the second portion 22.

In this way, when the second part 22 is connected to the first part 21, the projections of the first magnetic element 215 and the second magnetic element 222 on the bottom wall of the second part 22 at least partially coincide, and the separation distance between the first magnetic element 215 and the second magnetic element 222 is as small as possible. Typically, the first magnetic element 215 is spaced from the second magnetic element 222 by a distance of between 2mm and 3 mm; in a specific example, it may be 2.5mm. When the second portion 22 is coupled to the first portion 21, the first magnetic element 215 magnetically attracts the second magnetic element 222, thereby enabling the second portion 22 to be retained on the first portion 21.

In a preferred embodiment, the first magnetic element 215 is eccentrically disposed with respect to the second magnetic element 222. As shown in fig. 14, S1 is a center line of the second magnetic element 222, S2 is a center line of the first magnetic element 215, and the center line S1 and the center line S2 are not coincident, i.e., are spaced apart. Generally, the distance d (eccentric distance) between the center lines S1 and S2 is between 1mm and 2mm, and in a specific example, may be 1.5mm. Thus, when the second portion 22 is connected to the first portion 21, the second magnetic element 222 receives one force in the longitudinal direction (F1 in the drawing) and another force in the width direction (F2 in the drawing). The force F2 in the width direction is directed toward the left side wall of the first portion 21 or the second portion 22. In this way, production tolerances and assembly tolerances of the absorbent material are facilitated, and a minimum assembly gap can be ensured between the second part 22 and the first part 21 when they are connected. It should be noted that the longitudinal direction and the width direction can be defined with reference to the aerosol-generating device 200 shown in fig. 12, for example.

It should be noted that the description and drawings of the present application illustrate preferred embodiments of the present application, but are not limited to the embodiments described in the present application, and further, those skilled in the art can make modifications or changes according to the above description, and all such modifications and changes should fall within the scope of the claims appended to the present application.
