[0002] An advertising machine is a new generation of intelligent device. It constitutes a complete advertising broadcast control system through terminal software control, network information transmission, and multimedia terminal display, and conducts advertising promotion through multimedia materials such as pictures, texts, videos, and small plugins (weather, exchange rate, etc.).

[0003] In the prior art, display screens are usually provided on both sides of an outdoor advertising machine, thereby increasing the viewing angle of the advertisement and further improving the advertising effect. However, due to the large size of the display screen and the need to prevent water from entering the inside of the housing, most of the openings of the heat dissipation holes are located on the lower side. It is difficult for the heat between the two display screens to be discharged from the housing, and the filter screen at the heat dissipation hole is not convenient to remove for cleaning. Therefore, we have introduced an outdoor advertising machine. Content of the Utility Model

[0004] The purpose of the utility model is to provide an outdoor advertising machine, which can not only significantly improve the heat dissipation effect of the two display screens inside the housing, but also prevent water from entering the inside of the housing; during cleaning, the filter screen can be quickly disassembled, with high disassembly efficiency and reduced labor intensity of the staff, so as to solve the problems proposed in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] An outdoor advertising machine, including a housing, grooves are provided on both sides of the housing, mounting holes are opened at the bottom of the grooves, display screens are fixedly provided inside the two mounting holes, ventilation openings are opened at the top of the grooves, a filtering unit is provided at the ventilation openings on the upper side of the grooves, a vertical baffle is provided at the center inside the housing, an arc-shaped plate is fixedly provided under the baffle, the upper end of the baffle is fixedly connected to the top of the housing, a plurality of fans are installed at the upper ends of the two display screens inside the housing, a rectangular frame is provided under the ventilation opening, a filter screen is provided inside the rectangular frame, and a quick locking mechanism is provided between the rectangular frame and the groove.

[0007] Further, the quick locking mechanism includes a locking block and two strip-shaped blocks. The two strip-shaped blocks are respectively fixedly provided on both sides of the rectangular frame. A strip-shaped groove matching with the strip-shaped block is provided on the groove wall of the groove. A rectangular groove is provided on the upper side of the rectangular frame. A through hole is opened at the bottom of the rectangular groove. The locking block, a locking groove matching with the locking block is provided on the groove wall of the groove. A pull rod is provided inside the through hole. The upper end of the pull rod is fixedly connected to the locking block. A pull block is fixedly provided at the lower end of the pull rod. A spring is movably sleeved outside the pull rod inside the rectangular groove.

[0008] Furthermore, the wind directions of the two fans are arranged in the same direction.

[0009] Furthermore, an inclined surface is provided on the upper end of the locking block.

[0010] Furthermore, the angle of the inclined surface is set to 45°.

[0011] Furthermore, the side wall of the pull block is provided with a plurality of anti-slip protrusions.

[0012] Furthermore, the filter screen is configured as a stainless steel wire screen.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The outdoor advertising machine starts a plurality of fans through a display screen, a rectangular frame, a housing, a fan, a curved plate, a baffle, a strip block, a locking block, a spring, a pull rod, a pull block, and a filter screen. The wind directions of the plurality of fans are the same. After one group of fans inhales external cold air, the cold air is blocked by the baffle and moves downward, and takes away the heat of the display screen on one side during the downward movement. After the cold air is blocked by the curved plate, it bypasses the baffle and moves upward, and takes away the heat of the display screen on the other side during the upward movement. Then another group of fans discharges the cold air through the vents, which can significantly improve the heat dissipation of the two display screens. The display screen is located on the inner side of the shell, which has a heat dissipation effect and can also prevent water from entering the shell. The filter can filter dust in the air. When a large number of large dust particles and flocs are stuck in the filter, multiple filters need to be removed and cleaned together. When disassembling the rectangular frame, pull the pull block downward, and the pull block drives the locking block downward to squeeze the spring through the sliding rod. When the locking block moves out of the locking groove, the rectangular frame can be pulled outward and the strip block can be pulled out of the strip groove. The filter can be quickly disassembled during cleaning, and the disassembly efficiency is high, which reduces the labor intensity of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 5 , the present invention provides a technical solution:

[0023] An outdoor advertising machine includes a housing 3. Grooves are provided on both sides of the housing 3. Installation holes are opened at the bottom of the grooves. Display screens 1 are fixedly provided inside the two installation holes. Ventilation openings are opened at the top of the grooves. A filtering unit is provided at the ventilation openings on the upper side of the grooves. A vertical baffle 6 is provided at the center inside the housing 3. An arc plate 5 is fixedly provided below the baffle 6. The upper end of the baffle 6 is fixedly connected to the top of the housing 3. A plurality of fans 4 are installed at the upper ends of the two display screens 1 inside the housing 3. The wind directions of the two fans 4 are set in the same direction, so that one of the two ventilation openings can intake air and the other can exhaust air. A rectangular frame 2 is provided below the ventilation opening. A filter screen 12 is provided inside the rectangular frame 2. The filter screen 12 is set as a stainless steel wire mesh. The filter screen 12 can filter large particle dust in the air. The stainless steel material makes the filter screen 12 not easily corroded and rusted.

[0024] A quick locking mechanism is provided between the rectangular frame 2 and the groove. The quick locking mechanism includes a locking block 8 and two strip blocks 7. The two strip blocks 7 are respectively fixedly provided on both sides of the rectangular frame 2. The strip blocks 7 are horizontally arranged. Strip grooves matching the strip blocks 7 are provided on the groove walls of the grooves. A rectangular groove is provided on the upper side of the rectangular frame 2. A through hole is opened at the bottom of the rectangular groove. For the locking block 8, a locking groove matching the locking block 8 is provided on the groove wall of the groove. A pull rod 10 is provided inside the through hole. The upper end of the pull rod 10 is fixedly connected to the locking block 8. A pull block 11 is fixedly provided at the lower end of the pull rod 10. A spring 9 is movably sleeved outside the pull rod 10 inside the rectangular groove. The spring 9 is always in a compressed state. An inclined surface is provided at the upper end of the locking block 8. The angle of the inclined surface is set to 45°. The inclined surface facilitates the locking block 8 to be inserted into the locking groove, improving convenience. A plurality of anti-slip protrusions are provided on the side wall of the pull block 11. The anti-slip protrusions increase the anti-slip property of the side wall of the pull block 11, facilitating the pulling of the pull block 11.

[0025] During use, the blower 4 is started. The wind directions of the two groups of blowers 4 are the same. After one group of blowers 4 sucks in the external cold air, the cold air is blocked by the baffle 6 and moves downward. During the downward movement, the heat of one side of the display screen 1 is taken away. After the cold air is blocked by the arc-shaped plate 5, it bypasses the baffle 6 and moves upward. During the upward movement, the heat of the other side of the display screen 1 is taken away. Then the other group of blowers 4 discharges the cold air through the ventilation opening, which can significantly improve the heat dissipation effect of the two display screens 1 inside the housing 3. The filter net 12 can filter the dust in the air. When more large-particle dust and floccules are stuck in the filter net 12, it is necessary to remove multiple filter nets 12 and then clean them centrally. When disassembling the rectangular frame 2, pull down the pull block 11. The pull block 11 drives the locking block 8 to squeeze the spring 9 downward through the pull rod 10. When the locking block 8 moves out of the locking groove, the rectangular frame 2 can be pulled outwards and the strip-shaped block 7 can be pulled out of the strip-shaped groove. The filter net 12 can be quickly disassembled during cleaning, with high disassembly efficiency and reduced labor intensity of the staff.
