[0033] By setting up decorative part 2 and housing 1, a heat dissipation channel is formed between decorative part 2 and housing 1 to dissipate heat, thus meeting the heat dissipation requirements of the projection device; by reusing the first mounting hole 11 through which the projection lens passes as a heat dissipation channel, the aesthetics of housing 1 are improved, avoiding the reduction in aesthetics caused by additional heat dissipation holes 331 on housing 1, thus solving the problem of reduced aesthetics of housing 1 caused by heat dissipation holes 331 on housing 1.

[0034] Please see Figures 2-4 The decorative component 2 includes a first decorative part 21, a second decorative part 22, and a third decorative part 23 connected in sequence. In this embodiment, both the first decorative part 21 and the third decorative part 23 are arranged in a ring shape. The first mounting hole 11 and the second mounting hole 24 are both circular holes. One end of the second decorative part 22 is connected to the first decorative part 21, and the other end is connected to the third decorative part 23. The first decorative part 21 is located on one side of the housing 1, the second decorative part 22 passes through the first mounting hole 11, and the third decorative part 23 is located on the other side of the housing 1. The second mounting hole 24 passes through the first decorative part 21, the second decorative part 22, and the third decorative part 23. A first heat dissipation channel 25 is formed between the first decorative part 21 and the housing 1, and a second heat dissipation channel 26 is formed between the second decorative part 22 and the hole wall of the first mounting hole 11. The first heat dissipation channel 25 and the second heat dissipation channel 26 are connected, and heat can be discharged to the outside of the projection device through the second heat dissipation channel 26 and the first heat dissipation channel 25.

[0035] Please see Figure 2 and Figure 3Furthermore, a decorative groove 221 is provided on the side of the second decorative part 22 away from the housing 1. The groove wall of the decorative groove 221 is inclined towards the outer side of the second decorative part 22 along the direction from the third decorative part 23 to the first decorative part 21, so that the second decorative part 22 forms a trumpet-shaped structure, which is beneficial for the projection of the image by the lens of the projection device. Multiple decorative rings 222 are integrally formed on the groove wall of the decorative groove 221. The multiple decorative rings 222 are arranged sequentially along the direction from the third decorative part 23 to the first decorative part 21. The arrangement of the decorative rings 222 helps to improve the aesthetics of the decorative part 2, thereby improving the overall aesthetics of the projection device.

[0036] Please see Figure 3 and Figure 4 The projection device also includes a mounting component 3, which is located on the other side of the housing 1. The mounting component 3 covers the first mounting hole 11. The mounting component 3 has heat dissipation holes 331.
