[0002] Advertising refers to a systematic marketing activity in which enterprises, organizations or individuals pay to spread information to the public through specific media or strategies to achieve goals such as promoting products, shaping brands or guiding consumption.

[0003] In the process of using traditional advertising devices, the content to be advertised is often displayed through a display screen. In order to enable the display screen to display corresponding advertisement content and sound according to the needs of users, the content of the display screen is often changed through a console. After repeated use, bacteria are likely to be adsorbed on the surface of the console. Existing advertising devices are not convenient for disinfecting and sterilizing the console, and the display screen and the frame are often fixed, making it inconvenient to use different-sized display screens in combination with the frame according to the different pedestrian flows in the vicinity. Since the surface of the display screen is likely to adsorb dust during outdoor use, existing advertising devices are not convenient for cleaning the surface of the display screen, and the effect of saving resources during use is not good enough.

Through the drying component, the hot air of the console and the output device is extracted, and the external air is introduced into the frame. Part of the air will dry the disinfectant through the exhaust pipe, part of the air will be blown from the blowing pipe to the solar panel through the blowing head, and the air inside the blowing pipe will also enter the sliding shell, so that the cleaning component cleans and blows the front side of the display screen.

[0020] Advantages of the present invention: According to the size of the display screen, the first fan is used or the first fan and the second fan are used simultaneously, avoiding poor heat dissipation of a large display screen when the display screen is large and excessive resource waste when a small display screen is used. By using the solar panel, electric energy can be absorbed, playing a role in saving electric energy. The use of the square heat sink, the first circular heat sink, and the second circular heat sink can cool the passing gas, so that the temperature of the wind blowing on the surface of the solar panel and the display screen can be lowered. When the first fan is used or operates simultaneously with the second fan, external gas is extracted through the bottom of the frame body, so that air exchange can be performed on the inside of the frame body.

The inside of the piston 103g is hollow. When the piston 103g moves downward, the first ball 103d and the second ball 103k will rise. At this time, the suction pipe 103c will suck out the disinfectant liquid inside the liquid storage barrel 103a and spray it out from the pressing block 103j. Using the physical principle of controlling the gas pressure difference and balancing the spring force, their coordinated work realizes the one-way flow of the liquid, referring to the principle of the pressing pump.

[0048] Further, first, the support block 101c at the bottom of the display screen 101b is fitted to the top of the frame body 101a. The plug-in block 105a is inserted into the inside of the support block 101c, and the contact block 105c and the corresponding threaded hole 105b are fixed with bolts to fix the display screen 101b to the frame body 101a. If the installed contact block 105c touches the contact sensor 105d, the second fan 201c will run; otherwise, it will stop running.

[0049] When installing the display screen 101b, the bottom of the output device 101e will fit against the top of the telescopic tube 104a. The telescopic tube 104a will be squeezed to drive the connecting piece 104c to move downward, and the two mating blocks 104f will move downward. The two return springs 104e will deform, and the telescopic tube 104a will move downward inside the fixed tube 104b, allowing heat to enter the inside of the frame 101a. The display screen 101b will drive the baffle 101b-1 to move downward, and the baffle 101b-1 will squeeze the top of the sliding shell 203g, thereby changing the height of the sliding shell 203g.

[0050] When it is necessary to use the console 101d to change the content of the display screen 101b, by pulling the protective shell 102a upward, the two connecting magnets 102b at the bottom are separated from the two magnetic attraction magnets 102c at the bottom, and the protective shell 102a is moved upward until the two connecting magnets 102b at the top fit against the two magnetic attraction magnets 102c at the top. At this time, the protective shell 102a can be released, so that the console 101d can be used to control the output device 101e. After using the console 101d, the protective shell 102a is moved back to its original position, and the heat of the console 101d will enter the inside of the frame 101a.

[0051] When the protective shell 102a is pressed down, it will squeeze the pressing block 103j. When the pressing block 103j moves downward, the piston 103g will move downward. The piston 103g will squeeze the compression spring 103f. Due to the movement of the piston 103g, the air pressure inside the piston 103g and the liquid storage barrel 103a will change, causing the first ball 103d and the second ball 103k to move upward. At this time, the disinfectant liquid will be sprayed out from the pressing block 103j. Based on the physical principles of gas pressure difference control and spring force balance, their coordinated work realizes the one-way flow of the liquid. Referring to the principle of a pressing pump, the disinfectant liquid is sprayed onto the surface of the console 101d.

[0057] Specifically, the air discharged from the two air outlet blocks 201f can enter the interior of the protective shell 102a through the air outlet holes 101a-4, thereby drying the disinfectant solution on the surface of the console 101d. The gas inside the protective shell 102a can be discharged from the center of the top. The first fan 201b is in a normal use state. The operation of both the first fan 201b and the second fan 201c can extract the heat of the display screen 101b and the console 101d, and at the same time, the air outside the frame 101a can be drawn in from the bottom of the frame 101a to achieve cooling of the interior of the frame 101a. Part of the air extracted by the first fan 201b and the second fan 201c will enter the interior of the air duct 202a, and then be discharged from the air outlet head 202c through the vertical pipe 202b. The air discharged from the air outlet head 202c can blow to the top and bottom of the solar panel 101a-3 to achieve cleaning and heat dissipation. The top of the sliding shell 203g can fit with the bottom of the baffle 101b-1. The installation of the display screen 101b will change the position of the sliding shell 203g. There are multiple round holes inside both the moving shell 203f and the sliding shell 203g, and the aperture gradually decreases from the inside to the outside, and the air outlet path faces the front side of the display screen 101b. The height of the sliding shell 203g changes with the height of the display screen 101b and rebounds through the deformation of the elastic spring 203h. The square heat sink 201d-1, the first circular heat sink 202a-1, and the second circular heat sink 201e-1 all play a limiting role to reduce the temperature inside the air guide block 201d, inside the air duct 202a, and inside the exhaust duct 201e.

[0058] Furthermore, when the first fan 201b and the second fan 201c operate simultaneously, the heat at the bottom of the console 101d and the heat at the bottom of the fixed pipe 104b will be extracted, and the gas outside the frame 101a will be introduced into the interior of the frame 101a to achieve cooling. The gas extracted by the first fan 201b and the second fan 201c will enter the interior of the air guide block 201d, part of the gas will enter the interior of the exhaust duct 201e, and enter the interior of the air duct 202a. The gas entering the interior of the exhaust duct 201e will be discharged from the air outlet block 201f and blow into the interior of the protective shell 102a to dry the disinfectant solution, and then the gas will be discharged from the center of the top of the protective shell 102a.

[0059] The gas entering the interior of the air duct 202a will enter the interior of the vertical pipe 202b and finally be ejected from the air outlet head 202c. The gas ejected from the air outlet head 202c will blow to the top and bottom of the solar panel 101a-3 to achieve cleaning and heat dissipation of the top and bottom of the solar panel 101a-3. Part of the gas entering the interior of the vertical pipe 202b will enter the interior of the sliding shell 203g from the ventilation pipe 203j. The gas inside the sliding shell 203g will enter the interior of the moving shell 203f from the round holes on the left and right sides, and the gas inside the moving shell 203f will be discharged from the round holes on the left and right sides.

[0060] Run the motor 203c to drive the screw 203d to rotate. The screw 203d will cause the threaded block 203e to move in the left - right direction. The movement of the threaded block 203e will cause the moving shell 203f to drive the sliding shell 203g to move. The air blown out from the moving shell 203f and the sliding shell 203g will blow to the front side of the display screen 101b, thereby cleaning and dissipating heat from the front side of the display screen 101b.

[0061] It should be noted that the ventilation pipe 203j is made of flexible hose material and has elasticity.

[0062] The remaining structure is the same as that of the second embodiment.

[0063] Embodiment 4 Refer to Figures 1 to 12 , which is the fourth embodiment of the present invention. The difference between this embodiment and the third embodiment is that this embodiment provides an advertising device.

[0064] First, fit the support block 101c at the bottom of the display screen 101b to the top of the frame 101a. Insert the plug - in block 105a into the inside of the support block 101c, and use bolts to fix the contact block 105c to the corresponding threaded hole 105b, so as to fix the display screen 101b to the frame 101a. If the contact block 105c contacts the contact sensor 105d after installation, then run the second fan 201c; if not, stop running.

[0065] When installing the display screen 101b, the bottom of the output device 101e will fit against the top of the telescopic tube 104a. The telescopic tube 104a will be squeezed to drive the connecting member 104c to move downward, and cause the two mating blocks 104f to move downward. The two return springs 104e will deform. The telescopic tube 104a will move downward inside the fixed tube 104b, allowing heat to enter the inside of the frame 101a. The display screen 101b will drive the baffle 101b - 1 to move downward, and the baffle 101b - 1 will squeeze the top of the sliding shell 203g, thereby changing the height of the sliding shell 203g.

[0066] When it is necessary to use the console 101d to change the content of the display screen 101b, pull the protective shell 102a upward to separate the two bottom connecting magnets 102b from the two bottom magnetic - attracting magnets 102c. Move the protective shell 102a upward until the two top connecting magnets 102b fit against the two top magnetic - attracting magnets 102c. At this time, release the protective shell 102a, so that the console 101d can be used to control the output device 101e. After using the console 101d, move the protective shell 102a back to its original position. The heat of the console 101d will enter the inside of the frame 101a, and the rear side of the output device 101e can play the sound of the advertisement.

[0067] When the protective case 102a is pressed down, it will squeeze the pressing block 103j. When the pressing block 103j moves downward, the piston 103g will move downward. The piston 103g will squeeze the compression spring 103f. Due to the movement of the piston 103g, the air pressure inside the piston 103g and the liquid storage barrel 103a will change, causing the first ball 103d and the second ball 103k to move upward. At this time, the disinfectant liquid will be ejected from the pressing block 103j. Based on the physical principle of gas pressure difference control and spring force balance, their coordinated work realizes the one-way flow of the liquid. Referring to the principle of the pressing pump, the disinfectant liquid is sprayed onto the surface of the console 101d.

[0068] When the first fan 201b and the second fan 201c operate simultaneously, they will extract the heat at the bottom of the console 101d and the heat at the bottom of the fixed pipe 104b, and introduce the external gas of the frame 101a into the interior of the frame 101a to achieve cooling. The gas extracted by the first fan 201b and the second fan 201c will enter the interior of the air guiding block 201d. Part of the gas will enter the interior of the exhaust duct 201e and the interior of the blowing duct 202a. The gas entering the interior of the exhaust duct 201e will be discharged from the air outlet block 201f and blown into the interior of the protective case 102a to dry the disinfectant liquid, and then the gas will be discharged from the center of the top of the protective case 102a.

[0069] The gas entering the interior of the blowing duct 202a will enter the interior of the vertical pipe 202b and finally be ejected from the blowing head 202c. The gas ejected from the blowing head 202c will blow onto the top and bottom of the solar panel 101a-3 to clean and dissipate heat from the top and bottom of the solar panel 101a-3. Part of the gas entering the interior of the vertical pipe 202b will enter the interior of the sliding case 203g through the ventilation pipe 203j. The gas inside the sliding case 203g will enter the interior of the moving case 203f through the round holes on the left and right sides, and the gas inside the moving case 203f will be discharged from the round holes on the left and right sides.

[0070] Operate the motor 203c to drive the screw 203d to rotate. The screw 203d will cause the threaded block 203e to move in the left and right directions. The movement of the threaded block 203e will cause the moving case 203f to drive the sliding case 203g to move. The wind blown from the moving case 203f and the sliding case 203g will blow onto the front side of the display screen 101b, thereby cleaning and dissipating heat from the front side of the display screen 101b.

[0071] In summary, when the bottom of the display screen 101b is installed on the frame body 101a, if the contact sensor 105d is not in contact with the contact block 105c, the second fan 201c will not operate. If there is contact, the second fan 201c will operate. When the display screen 101b is small, only the first fan 201b operates, saving resources. When the display screen 101b is large, the first fan 201b and the second fan 201c operate simultaneously, enhancing the heat dissipation effect for the large display screen 101b. By closing the protective case 102a, the disinfection component 103 sprays disinfectant on the console 101d, which can prevent users from being infected by bacteria and improve safety. As the drying component 201 operates, the gas path will be changed. Some of the gas can dry the disinfectant, and some of the gas can blow to the top and bottom of the solar panel 101a-3 and the front side of the display screen 101b.
