DETAILED DESCRIPTION
[0020] The present invention is described in detail below in conjunction with the accompanying drawings. It should be noted that the directional words (front, back, left, and right) described in this embodiment are based on the directions shown in the accompanying drawings.
[0021] An integrated aluminum shell downlight, such as Figure 1-Figure 7 As shown, it includes a downlight housing 1, a mounting block 2, a lamp body 3, an electric motor 4, an outer gear 5, an inner gear 6, a sliding rod 7, a dust cleaning wipe 8 and a telescopic mechanism. The downlight housing 1 is installed in the mounting hole of the ceiling, and the mounting block 2 is clamped in the middle of the downlight housing 1. The downlight housing 1 and the mounting block 2 are both provided with mounting grooves for mounting circuit boards. The downlight housing 1 and the mounting block 2 are both made of aluminum. The downlight housing 1 and the mounting block 2 are integrally die-cast, which greatly improves the heat dissipation performance and strength, and the control circuit board and the current stabilizing circuit board can be firmly installed in the mounting groove, which is safe and reliable. A lamp body 3 is installed on the mounting block 2, and an electric motor 4 is installed on the rear side of the downlight housing 1. The output shaft of the electric motor 4 passes through the downlight housing 1, and an external gear 5 is fixedly connected to the output shaft of the electric motor 4. An internal gear 6 is rotatably connected to the outer wall of the downlight housing, and the internal gear 6 is meshed with the external gear 5. A sliding rod 7 is slidably connected to the outer wall of the internal gear 6, and the sliding rod 7 penetrates the outer wall of the internal gear 6. A cleaning wipe 8 is slidably connected to the side of the sliding rod 7 close to the center of the internal gear 6, and the cleaning wipe 8 is made of sponge. A telescopic mechanism is connected to the side of the sliding rod 7 away from the center of the internal gear 6.
[0022] When dust accumulates on the lamp surface of the lamp body 3, the electric motor 4 drives the outer gear 5 to rotate, and the rotation of the outer gear 5 drives the inner gear 6 to rotate, so that the dust cleaning wiper 8 on the sliding rod 7 rotates along the circumference of the lamp body 3, so that the lamp surface can be cleaned to prevent the dust on the lamp surface from hindering the heat dissipation of the aluminum shell downlight. When cleaning is not needed, the sliding rod 7 is moved away from the lamp surface through the telescopic mechanism.
[0023] like Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the telescopic mechanism includes a first elastic member 10, a support plate 11, a guide block 12, a connecting plate 13, a second elastic member 14 and a plug post 15. The first elastic member 10 is fixedly connected between the cleaning wipe 8 and the inner wall of the internal gear 6. The first elastic member 10 is set as a strong coil spring. The outer wall of the internal gear 6 is fixedly connected with the support plate 11. The top of the support plate 11 is fixedly connected with two guide blocks 12. The sliding rod 7 is slidably connected to the two guide blocks 12 at the same time. The front side of the left guide block 12 is fixedly connected with the second elastic member 14, the second elastic member 14 is set as a coil spring, the front side of the second elastic member 14 is fixedly connected with the connecting plate 13, and the rear side of the connecting plate 13 is fixedly connected with the plug post 15. The sliding rod 7 and the right guide block 12 are both provided with a socket 71 adapted to the plug post 15. The inner diameter of the socket 71 is larger than the outer diameter of the plug post 15. The plug post 15 remains in the socket 71 of the right guide block 12 and slides.
[0024] When the lamp surface is cleaned, the first elastic member 10 is in an extended state, the cleaning wipe 8 is in an expanded state, and the cleaning wipe 8 is close to the lamp surface, the second elastic member 14 is in a compressed state, and the rotation of the inner gear 6 drives the telescopic mechanism to rotate along the circumferential direction of the inner gear 6. When the lamp surface does not need to be cleaned, the sliding rod 7 is manually slid away from the lamp surface, the first elastic member 10 is compressed, and the sliding rod 7 slides along the guide block 12 in the direction away from the lamp surface, and the insertion hole 71 on the outer wall of the sliding rod 7 also moves to the right. When the insertion hole 71 moves to align with the plug post 15, the second elastic member 14 returns to its original state to insert the plug post 15 into the insertion hole 71, and the connecting plate 13 moves backward to approach the sliding rod 7, and the sliding rod 7 is inserted into the plug post 15. It is locked and no longer slides, so that the sliding rod 7 can be kept away from the lamp surface. At this time, the cleaning wipe 8 is in a compressed state to prevent the cleaning wipe 8 from blocking the light of the lamp body 3 and avoiding the cleaning wipe 8 from interfering with the normal use of the aluminum shell downlight. When cleaning is required, the connecting plate 13 is pushed away from the sliding rod 7 to allow the plug post 15 to be pulled out of the socket 71. The sliding rod 7 is no longer locked by the plug post 15, and the first elastic member 10 returns to its original state to reset the sliding rod 7 to the left. A limit plate is provided at the end of the sliding rod 7 away from the lamp surface. The limit plate can ensure that the sliding rod 7 slides and resets to the accurate position under the elastic force of the first elastic member 10. The second elastic member 14 is compressed, and then the cleaning operation can be performed.
[0025] like Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a cleaning block 9 is also included. The end of the sliding rod 7 close to the center of the inner gear 6 is fixedly connected with the cleaning block 9. The cleaning block 9 is cylindrical, and the front side of the cleaning block 9 is thinner than the rear side of the cleaning block 9. When the cleaning wipe 8 cleans the lamp surface, the cleaning wipe 8 pushes the dust from the edge of the lamp surface to the center of the lamp surface. The cleaning block 9 can clean the dust accumulated in the center of the lamp surface, thereby improving the cleaning efficiency.
[0026] like Figure 5 and Figure 7 As shown, it also includes a first wedge plate 16 and a second wedge plate 20. The first wedge plate 16 is fixedly connected to the left side of the bottom of the connecting plate 13, and the inclined surface of the first wedge plate 16 faces upward. The first wedge plate 16 is located inside the inner gear 6. The front side of the downlight housing 1 is fixedly connected to the second wedge plate 20 for extrusion-matching with the first wedge plate 16, and the inclined surface of the second wedge plate 20 faces downward. When the plug 15 is inserted into the insertion hole 71, the connecting plate 13 moves backward to cause the first wedge plate 16 to move backward as well, so that the first wedge plate 16 moves backward close to the downlight housing 1. When the electric motor 4 drives the outer gear 5 to rotate the inner gear 6, the second wedge plate 20 squeezes the first wedge plate 16, so that the first wedge plate 16 moves forward away from the inner gear 6, thereby causing the connecting plate 13 to move forward and the plug 15 to move away from the insertion hole 71, so that the sliding rod 7 slides to the left close to the lamp surface under the elastic force of the first elastic member 10, and there is no need to manually pull out the plug 15.
[0027] like Figure 1 and Figure 4 As shown, a pull ring 17 is also included. The end of the sliding rod 7 away from the center of the inner gear 6 is fixedly connected with the pull ring 17. The pull ring 17 can make the movement of the sliding rod 7 more convenient. Downlights are generally installed on the ceiling, and the sliding rod 7 cannot be directly touched by human hands. When the sliding rod 7 needs to be retracted using the telescopic mechanism, the pull ring 17 can be pulled toward the side away from the center of the inner gear 6 by using a tool.
[0028] like Figure 4 and Figure 6 As shown, it also includes a dust collecting frame 18 and a shielding plate 19. The pull ring 17 is fixedly connected with the shielding plate 19. The shielding plate 19 is hingedly connected with the dust collecting frame 18 on one side close to the lamp surface. A torsion spring is provided at the hinge of the dust collecting frame 18 and the shielding plate 19. When there is a lot of dust in the dust collecting frame 18, it is only necessary to press the dust collecting frame 18 forward to make it tilt forward, and then clean the dust collecting frame 18. When the dust collecting frame 18 is released, the dust collecting frame 18 is reset by the torsion spring. The dust collecting frame 18 is located directly in front of the dust cleaning wipe 8. The dust collecting frame 18 is semi-cylindrical. When cleaning the dust on the lamp surface, heavier dust will fall into the dust collecting frame 18 to prevent dust from polluting the environment. When the sliding rod 7 is retracted, the dust collecting frame 18 and the shielding plate 19 can both shield the telescopic mechanism to improve the aesthetics of the aluminum shell downlight.
[0029] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
