[0028] The embodiment of the present application discloses a heat-not-burn device, which includes a shell 10, a battery 30, a circuit board 40 and a wireless charging component. A mounting cavity 11 is formed inside the shell 10, and the shell wall of the shell 10 has an appearance surface facing away from the mounting cavity 11; the battery 30 and the circuit board 40 are both located in the shell 10, and the battery 30 and the circuit board 40 are electrically connected. The wireless charging component includes a charging coil 21 and a wireless charging module (not shown in the figure). The charging coil 21 is installed on the shell 10, specifically on the shell wall of the shell 10. The wireless charging module and the appearance surface of the shell 10 are spaced apart in the shell wall thickness direction, so that the charging coil 21 is not exposed, which helps Ensure the appearance of the entire heat-not-burn device; the wireless charging module is arranged on the circuit board 40, and the wireless charging module may include a wireless charging circuit arranged on the circuit board 40 and a wireless charging chip installed on the circuit board 40. The wireless charging circuit is electrically connected to the wireless charging chip, and the wireless charging module as a whole is electrically connected to the charging coil 21.

[0029] Specifically, in some embodiments, please refer to Figures 1 to 5 The heating without burning device includes an atomization assembly 50 located in the installation cavity 11 of the shell 10, the atomization assembly 50 has an atomization channel, and the heating without burning device is arranged in the extension direction of the atomization channel. The heating without burning device has a first direction and a second direction arranged perpendicular to the extension direction of the atomization channel. The cross-sectional shape of the shell 10 perpendicular to the extension direction of the atomization channel is square, which can be a rectangle or a square. The first direction and the second direction are respectively the width direction and the length direction of the cross-sectional shape of the shell 10, or the extension direction of two adjacent sides of the square cross-sectional shape of the shell 10.

[0030] The housing 10 comprises a first housing wall 12 and a second housing wall 13 arranged opposite each other in a first direction. The first housing wall 12 and the second housing wall 13 are arranged parallel to each other and perpendicular to the first direction. The charging coil 21 can be mounted on the first housing wall 12. In one embodiment, the housing 10 is made of plastic. The charging coil 21 can be integrally molded onto the inner wall of the first housing wall 12 facing the mounting cavity 11 via in-mold printing, or can be integrally molded within the first housing wall 12 via overmolding. In a preferred embodiment, in-mold printing improves the positioning accuracy of the charging coil 21 within the housing 10 and improves the yield rate. The exterior surface of the housing 10 includes the first outer wall of the first housing wall 12 facing away from the mounting cavity 11. The charging coil 21 is spaced apart from the first outer wall in the thickness direction of the first housing wall 12. This prevents the charging coil 21 from being exposed outside the housing 10, thereby enhancing the appearance of the heat-not-burn device.

[0031] In one embodiment, please refer to Figures 1 to 4 The shell body 10 includes a shell body 16 and a substrate 17. The shell body 16 includes a second shell wall 13 and at least part of the first shell wall 12. The shell body 16 has a mounting position, which is located at the first shell wall 12. The substrate 17 is located at the mounting position and is connected to the shell body 16. The substrate 17 and the shell body 16 are arranged in a first direction. The thickness direction of the substrate 17 is in the same direction as the first direction. The substrate 17 has a first mounting surface 171 facing the shell body 16 in the first direction. The shell body 16 has a second mounting surface 162 facing the substrate 17 in the first direction at the mounting position.

[0032] The housing body 16 and the base plate 17 can be made of different materials. For example, the housing body 16 can be made of metal to enhance the quality of the housing 10, while the base plate 17 can be made of plastic. The charging coil 21 can be fixed to the first mounting surface 171 of the base plate 17 by in-mold printing. Alternatively, the charging coil 21 can be molded into the base plate 17 by overmolding, with the external connection end of the charging coil 21 exposed on the base plate 17. The outer surface of the base plate 17, facing away from the housing body 16 in the first direction, forms part of the exterior surface of the housing 10. The charging coil 21 is spaced apart from the outer surface of the base plate 17 along the thickness direction of the base plate 17 to prevent the charging coil 21 from being exposed on the housing 10, thereby ensuring the integrity and consistency of the heat-not-burn device's appearance. In this embodiment, the base plate 17 and the housing body 16 are made of different materials. The base plate 17, which is made of a different material than the housing body 16, can be used to determine the position of the charging coil 21 on the housing 10, thereby facilitating alignment of the charging coil 21 with the transmitting coil on an external wireless charging device and facilitating charging of the heat-not-burn device.

[0033] In another embodiment, please continue to refer to Figures 1 to 4The shell 10 and the substrate 17 can both be made of plastic material, and the charging coil 21 can be integrally formed or fixed on the first mounting surface 171 or the second mounting surface 162 by in-mold printing, so that the charging coil 21 and the outer side surface of the substrate 17 are spaced apart in the thickness direction of the substrate 17 to ensure the appearance of the heat-not-burn device.

[0034] In one embodiment, in order to further improve the consistency of the appearance of the heat-not-burn device, please refer to Figure 1 and Figure 2 The shell body 16 is provided with a mounting groove 161 at the mounting position. The mounting groove 161 can be a rectangular structure. The shape of the substrate 17 matches the shape of the mounting groove 161, and the thickness of the substrate 17 is equal to the groove depth of the mounting groove 161. The substrate 17 can be fixed in the mounting groove 161 by interference fit or by gluing, so that the substrate 17 can be just installed in the mounting groove 161, and the outer side surface of the substrate 17 facing away from the shell body 16 in the first direction is flush with the outer surface of the shell body 16 on the first shell wall 12 facing away from the mounting cavity 11 in the first direction, thereby improving the consistency of the appearance of the heat-not-burn device.

[0035] Of course, in other embodiments, the substrate 17 may also be arranged to protrude from the shell body 16 , or the outer side surface of the substrate 17 may be lower than the outer surface of the shell body 16 at the first shell wall 12 .

[0036] In an embodiment in which the charging coil 21 is fixed to the first mounting surface 171 by in-mold printing, insulating glue (not shown) is applied to the first mounting surface 171 of the substrate 17 and the portion of the charging coil 21 exposed on the first mounting surface 171. The substrate 17 with the charging coil 21 mounted thereon is fixedly connected to the metal shell body 16 via the insulating glue, thereby achieving insulation between the charging coil 21 and the shell body 16.

[0037] For some examples, please refer to Figure 2 、 Figure 3 and Figure 5 The charging coil 21 mounted on the housing 10 is connected to the circuit board 40 within the housing 10 via an electrical connector. The bottom wall of the mounting slot 161 on the housing body 16 serves as the second mounting surface 162. The substrate 17 is secured to the second mounting surface 162 by adhesive. In embodiments where the charging coil 21 is mounted on the first mounting surface 171 or the second mounting surface 162, or is integrally formed within the substrate 17, a through hole 163 is provided on the bottom wall of the mounting slot 161, communicating with the mounting cavity 11 within the housing 10. An electrical connector is provided through this through hole 163.

The size of the through hole 163 is slightly larger than the cross-sectional size of the electrical connector. The size of the through hole 163 is only sufficient to allow the electrical connector to pass through, thereby reducing the probability of external foreign matter or dust entering the mounting cavity 11 through the through hole 163. Of course, in other embodiments, a second mounting surface 162 can be arranged around the through hole 163 to ensure the sealing at the connection position between the substrate 17 and the shell body 16. In the embodiment in which the substrate 17 is connected to the shell body 16 by gluing, no glue layer is provided at the position corresponding to the through hole 163 on the substrate 17, and the charging coil 21 is exposed to the substrate 17 at the position of the through hole 163 to facilitate the electrical connection between the charging coil 21 and the electrical connector passing through the through hole 163.

[0039] In an embodiment in which the substrate 17 is not provided on the housing 10 and the charging coil 21 is molded within the first housing wall 12 by overmolding, the through hole 163 is not provided on the housing 10. The external connection end of the charging coil 21 is exposed on the inner side surface of the housing 10 to facilitate electrical connection of the charging coil 21 to the circuit board 40 within the mounting cavity 11 via an electrical connector.

[0040] For some examples, please refer to Figure 2 and Figure 3 The electrical connector includes a flexible circuit board 60.

The first mounting surface 171 or the second mounting surface 162 on which the charging coil 21 is located is perpendicular to the circuit board 40. In one embodiment, the flexible circuit board 60 is generally an L-shaped plate structure, with the width of the flexible circuit board 60 oriented in the same direction as the atomization channel extension. The flexible circuit board 60 includes a first portion 61 and a second portion 62 arranged along its length.

The charging interface 141 and the charging connector 41 are arranged correspondingly. When the battery 30 cannot be charged through an external wireless charging device, the battery 30 can be charged through the charging interface 141 and the charging connector 41 by wired charging.

[0046] Accordingly, in order to prevent external foreign matter from entering the installation cavity 11 through the charging interface 141, a plug can be provided in one embodiment to seal the charging interface 141 and the charging connector 41 to improve the reliability of the entire heat-not-burn device.
