DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0024] Example:

[0025] like Figure 1-Figure 6 As shown, the present invention provides a technical solution for an LED advertising light box:

[0026] As shown in the figure, an LED advertising light box, the structure of which includes a light box body 1 and a support base 2 on the lower surface of the light box body 1, the light box body 1 includes a light box body 11, a bottom plate 12 arranged on the lower surface of the light box body 11 and a cover plate 13 arranged on the upper surface of the light box body 11, the light box body 11 includes a light box frame 111, a guide plate 112 symmetrically installed on the left and right sides of the inner wall of the light box frame 111, a movable push plate 113 matched with the guide plate 112, a wiping frame 114 arranged on the surface of the movable push plate 113 and movably fitted with the guide plate 112, a support screw 115 matched with both sides of the movable push plate 113, a sealing frame strip 116 arranged at the edge of the lower surface of the light box frame 111 and a sealing frame strip 116 arranged on the four sides of the lower surface of the light box frame 111 The bottom plate 12 comprises a bottom plate body 121, a sleeve hole 122 provided in the middle of the lower surface of the bottom plate body 121, a water collecting collar 123 provided inside the sleeve hole 122 and matched therewith, a support frame 124 which fits with the sleeve hole 122 and whose end is connected to the support base 2, a filter ring 125 which is provided on the upper surface of the support frame 124 and connected to the upper edge of the water collecting collar 123, an inclined plate 126 which is symmetrically installed on the inner surface of the bottom plate body 121, a groove sleeve edge 127 which is provided at the four corners of the bottom plate body 121 and matched with the sealing frame strip 116, and a positioning sleeve 128 which is provided at the four corners of the groove sleeve edge 127 and corresponds to the positioning rod 117.

[0027] The guide plate 112 is arranged in an eight-shaped structure, and the side with the largest opening faces outward. The guide plate 112 is made of a mirror material and is used to reflect the light generated by the LED light strip, thereby enhancing the high brightness of the LED advertising light box.

[0028] Both ends of the movable push plate 113 are provided with through holes adapted to the support screw 115 , and both ends of the movable push plate 113 are provided with driving screw nuts.

[0029] The number of wiping frames 114 is the same as that of guide plates 112, and they are arranged correspondingly. An absorbent cotton layer is arranged inside the wiping frame 114 to wipe the dust and moisture on the surface of the guide plate, so as to keep the inside of the advertising light box dry.

[0030] A water-absorbing sponge is arranged inside the water-collecting collar 123 , and the water-collecting collar 123 and the bottom plate body 121 are arranged in a detachable structure.

[0031] A driving motor and a humidity sensor are provided at the connection position between the cover plate 13 and the support screw 115, which are used to sense the humidity in the light box body. When the humidity reaches the set value, the driving motor will be energized, so that the movable push plate can move up and down with the cooperation of the support screw, so as to wipe the moisture and dust retained on the surface of the guide plate.

[0032] It should be noted that an LED light strip is arranged inside the light box body 11, and the control power supply of the advertising light box is an external power supply. This arrangement is a prior art and will not be described any more.

[0033] The specific implementation principle is as follows: guide plates 112 are set on the left and right sides of the advertising light box body 1. Since the guide plates 112 are mirror structures, when the LED light bar inside the light box body 11 is lit, the light generated can be reflected again with the mirror setting, thereby enhancing the overall brightness of the light box body 1 and avoiding the phenomenon of dim brightness on both sides of the light box body 11. When the humidity sensor set on the cover plate 13 detects that the humidity inside the light box body 11 is greater than the set value, it cooperates with the drive motor to realize the activity The push plate 113 pushes back and forth on the support screw 115, so that the wiping frame 114 wipes back and forth the moisture and dust retained on the surface of the guide plate 112, and the moisture that falls after wiping cooperates with the inclined plate 126 to fall into the water collecting ring 123. At the same time, the water collecting ring 123 is provided with a water-absorbing sponge, which can expand and absorb the moisture to prevent it from gathering and causing odor. In addition, the water collecting ring 123 is detachable, so the water collecting ring 123 can be disassembled and cleaned regularly, and its water-absorbing sponge can be replaced.

[0034] Since the filter ring 125 is disposed on the upper portion of the support frame 124 , foreign objects larger than the filter ring 125 can be isolated.

[0035] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the attached claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution.
