The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] See Figure 1 , Figure 1 The diagram shows a schematic of a charger according to an embodiment of the present invention. The charger includes an upper housing 1, a lower housing 2, a decorative housing 3, a plug 4, and a charging circuit module 5. The decorative housing 3 is built into the upper housing 1, the charging circuit module 5 is disposed within the decorative housing 3, the plug 4 is disposed in the lower housing 2 and electrically connected to the charging circuit module 5, and the lower housing 2 is fixedly connected to the decorative housing 3 and the upper housing 1. The upper housing 1 is made of transparent material, and one side of the decorative housing 3 is an opening.

[0027] In this embodiment, the upper shell 1 can be made of transparent material such as glass or transparent plastic, wherein the plastic is a high-temperature resistant plastic to absorb the heat dissipated by the heating components. The charging circuit module 5 can be fixedly connected to the decorative shell 3 or the lower shell 2, preferably fixedly connected to the decorative shell 3. In this embodiment, the charging circuit module 5 is placed inside the decorative shell 3 to isolate the heat dissipation of the heating components 52 in the charging circuit module 5 without the need for additional heat sinks, effectively improving the shell temperature rise problem and reducing costs; at the same time, the opening on one side of the decorative shell 3 allows the circuit board 51 to be seen through the upper shell 1, making the charger look more exquisite and technologically advanced.

[0028] In some embodiments, the outer surface of the decorative housing 3 is provided with a surface-treated decorative element so that the surface-treated decorative element of the decorative housing 3 can be directly seen through the transparent material of the upper housing 1, thereby improving the aesthetic appearance of the charger.

[0029] Optionally, the surface-treated decorative part can be a water transfer pattern, a water decal pattern, an electroplated pattern, a screen-printed pattern, a laser engraving pattern, and / or a spray-painted pattern. By using patterns with various processing methods as decorations on the outer surface of the decorative housing 3, the needs of different users for different patterns can be met; at the same time, the decorative housing 3 is surrounded by the upper housing, which can protect the pattern from wear and tear during use and improve the durability of the decorative part.

[0030] In some embodiments, as Figure 2 and Figure 3 As shown, the charging circuit module 5 includes a circuit board 51 and a heating element 52 disposed on the circuit board. The circuit board 51 is adapted to the opening and disposed at the opening. The heating element 52 is surrounded by the decorative housing 3.

[0031] In this embodiment, the decorative housing 3 surrounds the heat-generating components so that the heat generated by the heat-generating components is not conducted to the charger housing (upper housing 1) in large quantities. This solves the problem of temperature rise of the charger housing without the need for additional metal heat sinks, effectively reducing costs.

[0032] Optionally, the plane on which the circuit board 51 is located is parallel to the plane on which the opening is located, so that the circuit board 51 faces the upper housing 1, allowing the user to see the circuit board 51 through the upper housing 1. The components on the circuit board 51 provide the charger with a strong sense of technology and improve its aesthetics. At the same time, the circuit board 51 effectively seals the opening, reducing the heat dissipation of the heat-generating components 52 to the upper housing 1 and alleviating the temperature rise of the charger casing.

[0033] Optionally, one end of the circuit board 51 is fixedly connected to the lower housing 2 so that the charging circuit module is separated from the decorative housing 3 and the upper housing 1, so that the charging circuit module 5 will not be interfered with when the decorative housing 3 and the upper housing 1 are disassembled.

[0034] In some embodiments, as Figure 4 and Figure 5 As shown, the circuit board 51 is electrically connected to the pin 4 via a metal spring 6. The metal spring 6 is fixedly connected to the lower housing 2, and one end of the metal spring 6 abuts against the circuit board 51, while the other end of the metal spring 6 abuts against the pin 4.

[0035] Optionally, the metal spring 6 includes an L-level spring 61 and an N-level spring 62.

[0036] In this embodiment, the L-level spring contact 61 and the N-level spring contact 62 are used to connect the pin 4 to improve the connection stability between the circuit board 51 and the pin 4.

[0037] In some embodiments, the lower housing 2 is detachably and fixedly connected to the decorative housing 3 and the upper housing 1 respectively, so as to facilitate the replacement of decorative housing 3 with different decorative parts and meet the user's personalized needs.

[0038] Optionally, the transparent material of the upper housing 1 is a colored transparent material to improve the aesthetics of the charger and meet the color requirements of different users.

[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
