[0024] The present invention will now be described in conjunction with specific embodiments.

[0025] Example 1, as Figures 1 to 3 As shown, a hidden exhaust structure for a power adapter is disclosed. The power adapter includes an adapter housing 1, a PCB circuit board 2, conductive springs 4, metal pins 3, and an output line 5. The metal pins 3 are electrically connected to the PCB circuit board 2 through the conductive springs 4. The adapter housing 1 includes a main housing 11 and a cover 12 installed at the upper end of the main housing 11. The adapter housing 1 has an internal cavity 13 formed by the main housing 11 and the cover 12. The PCB circuit board 2 is embedded in the cavity 13.

[0026] Among them, such as Figures 1 to 4 As shown, the outer sheath of the output line 5 is injection molded with a retaining plastic part 6, which is snapped between the main housing 11 and the cover 12. The inner end of the output line 5 extends into the housing cavity 13 and is electrically connected to the PCB circuit board 2.

[0027] Furthermore, such as Figures 1 to 4 As shown, the retaining component 6 has an inner stop 61 and an outer stop 62 arranged at intervals. The inner stop 61 is located inside the housing cavity 13, and the outer stop 62 is located outside the adapter housing 1. The retaining component 6 has a retaining groove 63 formed between the inner stop 61 and the outer stop 62, and the main housing 11 and the cover 12 are respectively inserted into the retaining groove 63.

[0028] Furthermore, such as Figures 1 to 4 As shown, the retaining rubber part 6 has an exhaust groove 64. The inner end of the exhaust groove 64 passes through the inner stop 61 of the retaining rubber part 6, and the outer end of the exhaust groove 64 extends to the outer stop 62 of the retaining rubber part 6.

[0029] It should be explained that the retaining rubber part 6 has one venting groove 64; or, the retaining rubber part 6 has two symmetrically arranged venting grooves 64; or, the retaining rubber part 6 has at least three venting grooves 64 distributed in a ring array.

[0030] It should be noted that during the process of the retaining rubber part 6 being held and fixed by the main housing 11 and the cover 12, the main housing 11 and the cover 12 are respectively inserted into the retaining groove 63 between the inner stop 61 and the outer stop 62. Through the cooperation of the inner stop 61 and the outer stop 62, the retaining rubber part 6 is limited and fixed between the main housing 11 and the cover 12.

[0031] It should be emphasized that, regarding the venting groove 64 formed on the retaining rubber part 6, since the inner end of the venting groove 64 penetrates the inner stop 61 of the retaining rubber part 6, that is, the inner end of the venting groove 64 communicates with the outer shell receiving cavity 13 of the adapter housing 1; and since the outer end of the venting groove 64 extends to the outer stop 62 of the retaining rubber part 6, that is, the outer end of the venting groove 64 directly communicates with the outside of the adapter housing 1, the venting groove 64 with this structural design can effectively play a role in venting.

[0032] It should be further emphasized that the exhaust groove 64 in this embodiment is hidden in the retaining groove 63, and this hidden structure design will not affect the appearance of the power adapter.

[0033] In summary, the concealed exhaust structure of the power adapter in this embodiment has the advantage of novel structural design and does not affect the appearance of the power adapter.

[0034] Example 2, as Figure 4 As shown, the difference between this embodiment 2 and embodiment 1 is that the portion of the exhaust groove 64 located on the outer baffle 62 opens outward.
