When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0026] Reference Figure 1-Figure 3 , which is an embodiment of the utility model, provides a multimedia display device, including a frame unit 100, a cleaning unit 200 and an adjustment unit 300.

[0027] The frame unit 100 includes a base 101 and an installation box 103 matched with the base 101. Universal wheels 102 are fixedly installed at the four corners of the bottom of the base 101. A display screen 104 is arranged at the top of the base 101. The universal wheels 102 can move the device to a designated location.

[0028] The cleaning unit 200 includes a mounting base 202 symmetrically mounted at the bottom of the display screen 104, and the tops of the two groups of mounting bases 202 are rotatably connected to a movable rod 203 and a screw rod 205, respectively. A motor 206 is fixedly mounted at the bottom of one group of mounting bases 202, and the output end of the motor 206 is fixedly connected to one end of the screw rod 205. The outer surface of the movable rod 203 is slidably connected to a first slider 208, and the outer surface of the screw rod 205 is threadedly connected to a second slider 209, and a rotating rod 210 is fixedly mounted on the opposite surface of the second slider 209 and the first slider 208. The opposite surfaces of the two groups of rotating rods 210 are fixedly mounted. There is a cleaning block 207, and one side of the cleaning block 207 is in contact with the surface of the display screen 104. The motor 206 is started, and the motor 206 drives the screw rod 205 to start rotating. Since the second slider 209 is threadedly connected to the screw rod 205, and the second slider 209 and the first slider 208 are both connected to the cleaning block 207, the first slider 208 limits the second slider 209, ensuring that the second slider 209 moves up and down on the surface of the screw rod 205, driving the cleaning block 207 to move, so that the cleaning block 207 can wipe off the dust on the surface of the display screen 104, thereby improving the user's viewing experience.

[0029] A water tank 201 is fixedly installed on the top of the display screen 104. A plurality of extrusion columns 211 are provided at the bottom of the inner cavity of the water tank 201. A sealing plug 216 is slidably connected to the inner cavity of the extrusion column 211. The extrusion column 211 can seal the water outlet 204 to prevent the water inside the water tank 201 from flowing out.

[0030] A plurality of extrusion columns 211 are fixedly installed on the top of the cleaning block 207, and the positions of the extrusion columns 211 correspond one to one with the positions of the water outlet 204. The diameter of the extrusion columns 211 is smaller than the diameter of the water outlet 204. When the cleaning block 207 moves to the top, the extrusion columns 211 will squeeze the sealing plug 216 out of the water outlet 204, so that the water in the inner cavity of the water storage tank 201 flows into the surface of the cleaning block 207. When the cleaning block 207 moves downward, the wet cleaning block 207 can further improve the cleaning effect.

[0031] The inner cavity of the water tank 201 is symmetrically provided with a first slide groove 212, and a telescopic spring 213 is fixedly installed on the top of the first slide groove 212, and a third slider 214 is fixedly installed on the bottom end of the telescopic spring 213, and the third slider 214 is slidably connected to the first slide groove 212, and a connecting strip 215 is fixedly installed on the opposite surface of the third slider 214, and the bottom end of the connecting strip 215 is fixedly connected to the sealing plug 216. When the sealing plug 216 moves upward, the third slider 214 will squeeze the telescopic spring 213. When the squeezing column 211 moves downward, the elastic force of the telescopic spring 213 is released, and the sealing plug 216 is ejected downward, thereby completing the blocking of the water outlet 204.

[0032] The adjustment unit 300 includes a threaded rod 303 fixedly installed in the inner cavity of the installation box 103, a knob 305 is fixedly installed on the top of the threaded rod 303, a supporting plate 304 is threadedly connected to the outer surface of the threaded rod 303, a moving rod 307 is symmetrically installed on the top of the supporting plate 304, and the top of the moving rod 307 is fixedly connected to the bottom of the display screen 104, and a through hole 306 is symmetrically opened on the top of the installation box 103, and the through hole 306 and the moving rod 307 are slidably connected, and the threaded rod 303 is driven to rotate by the knob 305, and the threaded rod 303 can drive the two groups of moving rods 307 to move vertically, and the two groups of moving rods 307 can drive the upper display screen 104 to move vertically, thereby realizing the function of adjusting the height of the display screen 104, ensuring that the rear user can see the content.

[0033] The inner cavity of the installation box 103 is symmetrically provided with a second slide groove 301, and the inner cavity of the second slide groove 301 is slidably connected with a fourth slider 302, and the opposite surface of the fourth slider 302 is fixedly connected to the two sides of the supporting plate 304, thereby improving the stability of the supporting plate 304 during the moving process.

[0034] During use, the universal wheel 102 moves the device to a designated location, and the knob 305 drives the threaded rod 303 to rotate. The threaded rod 303 can drive the two sets of moving rods 307 to move vertically. The two sets of moving rods 307 can drive the upper display screen 104 to move vertically, thereby realizing the function of adjusting the height of the display screen 104 to ensure that the rear user can see the interior. The motor 206 is started, and the motor 206 controls the cleaning block 207 to move up and down. When the cleaning block 207 moves to the top, the extrusion column 211 squeezes the sealing plug 216 out of the water outlet 204, so that the water in the inner cavity of the water storage tank 201 flows into the surface of the cleaning block 207. When the sealing plug 216 moves upward, the third slider 214 squeezes the telescopic spring 213. When the cleaning block 207 moves downward, the elastic force squeezed by the telescopic spring 213 is released, and the sealing plug 216 pops out downward to complete the blocking of the water outlet 204. The wet cleaning block 207 can improve the cleaning of the display screen 104, so that the cleaning block 207 can wipe the dust on the surface of the display screen 104. When the cleaning block 207 moves to the bottom, the cleaning block 207 can be rotated by the rotating rod 210, so that the wet and dry side of the cleaning block 207 wipes the surface of the screen to avoid leaving water marks, thereby improving the user's viewing experience.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
