A moving block 6 is connected to the outer wall of the middle of the lead screw 5 through a bearing thread. The moving block 6 is embedded in the driving box 4. A driving rod 7 is connected to the bottom of one outer wall of the moving block 6. A limit ring 8 is connected to one side of the top of the driving rod 7. An electric push rod 9 is connected to the upper part of one outer wall of the moving block 6. The output end of the electric push rod 9 is connected with a moving frame 10. The limit ring 8 is embedded in the frame groove of the moving frame 10. A guide rod 11 is connected to the inner wall of the middle of the moving frame 10. The guide rod 11 penetrates through the limit ring 8. Display boards 12 are connected to the ends of the two moving frames 10 through bolts. The display boards 12 correspond to the transparent display door 3.

[0020] Among them, the display cabinet body 1 plays a supporting role. The objects to be displayed can be placed and displayed through multiple display platforms 2, and then protected by the transparent display door 3. The transparent display door 3 is made of transparent glass material, which is convenient for people outside the display cabinet body 1 to observe and appreciate. The driving box 4 is specifically a trough-shaped body with an open side. Through the driving box 4, the lead screw 5 can be supported to rotate. The rotation of the lead screw 5 drives the moving block 6 to perform lifting and translational movements, so as to clean the transparent display door 3 in all directions up and down. When cleaning, the lifting of the moving block 6 can drive the driving rod 7 to move synchronously. The driving rod 7 drives the moving frame 10 and the display board 12 to perform synchronous lifting movements, so as to displace the cleaning pad 15 up and down. At the same time, the electric push rod 9 can push the moving frame 10 to perform translational movements in the horizontal direction, thereby driving the display board 12 to perform synchronous translational movements in the horizontal direction, so as to make the cleaning pad 15 closely adhere to the transparent display door 3, so as to better clean it.

[0021] Embodiment 2 On the basis of Embodiment 1, the solution in Embodiment 1 will be further refined and introduced in combination with the following specific working methods, as Figures 1 to 7 shown, for details, see the following description: As a preferred embodiment, springs 13 are arranged in a row below the outer wall on one side of the display board 12 close to the transparent display door 3.

The servo motor 27 drives the lead screw 5 to rotate. When one side lead screw 5 rotates, it drives the corresponding drive gear 25 to rotate synchronously. The rotation of the drive gear 25 drives the drive belt 26 to rotate. The rotation of the drive belt 26 drives the two drive gears 25 to rotate synchronously, thereby driving the two lead screws 5 to rotate synchronously. Among them, the drive belt 26 is located at the top of the display cabinet 1 and is covered with a protective cover at the same time. The servo motor 27 plays a driving role and can drive the lead screw 5 to rotate. Through the cooperative rotation of the drive gear 25 and the drive belt 26, the two lead screws 5 can rotate synchronously, so as to synchronously control the lifting movement of the display board 12.

[0024] As a preferred embodiment, a movable groove 28 is provided on one side of the bottom of the display cabinet 1. A water collecting tray 29 is embedded in the middle of the movable groove 28. An electric telescopic rod 30 is connected to the inner wall of one side of the movable groove 28. The output end of the electric telescopic rod 30 is connected to the outer wall of the water collecting tray 29. A water collecting tank 31 is connected to the bottom end of the display cabinet 1 on the side far from the transparent display door 3. Among them, the water collecting tray 29 can move horizontally inside the movable groove 28. During the cleaning process of the display cabinet, the electric telescopic rod 30 can be used to push the water collecting tray 29 out of the movable groove 28. The cleaning liquid dripping during the cleaning process can be collected by the water collecting tray 29, preventing the cleaning liquid from dripping on the ground and causing water accumulation on the ground. The waste water collected by the water collecting tray 29 can flow into the water collecting tank 31 through the drain pipe 32 for collection for subsequent cleaning.

[0025] As a preferred embodiment, a drain pipe 32 is communicated with one side of the water collecting tank 31.

The slider 34 is embedded in the slideway 33. Among them, the drain pipe 32 serves to connect the water collecting tank 31 and the water collecting tray 29. At the same time, the drain pipe 32 has a certain degree of flexibility, enabling it to still play a guiding role during the movement of the water collecting tray 29. The slider 34 embedded in the slideway 33 plays a limiting role.

[0026] As a preferred embodiment, humidity and temperature sensors 35 are provided on both the inner and outer walls of the display cabinet 1. At the center of the outer wall at the top of the display cabinet 1, a dust and moisture-proof mechanism 36 is provided. The dust and moisture-proof mechanism 36 includes a ventilation box 37, an air inlet 38, a dust removal filter screen 381, an air duct 39, a fan 40, and an activated carbon filter layer 41. The air inlets 38 are arranged on the surface of the ventilation box 37, and the dust removal filter screen 381 is provided on the surface of the air inlet 38. Among them, by providing humidity and temperature sensors 35 on both the inner and outer walls of the display cabinet 1, the humidity conditions in different internal and external environments can be detected, so as to facilitate the moisture-proof work inside the display cabinet 1. When it is detected that the external humidity is lower than the internal humidity, the external dry air can enter through the air inlet 38 of the ventilation box 37, pass through the filtration of the dust removal filter screen 381, and then enter the display cabinet 1 through the air duct 39, thereby playing a role in moisture-proofing.

[0027] As a preferred embodiment, the bottom end of the ventilation box 37 is connected to the inside of the display cabinet 1 through the air duct 39. A fan 40 is provided in the middle of the ventilation box 37, and an activated carbon filter layer 41 is provided in the middle of the air duct 39. A drying box 42 is provided on one side inside the display cabinet 1. Among them, the external air flow is blown into the display cabinet 1 by the fan 40. After the external dry air flow further absorbs moisture through the activated carbon filter layer 41, the dry and clean air flow is blown into the display cabinet 1 to keep the inside dry, so that the inside is in a positive pressure environment. The air flow is discharged through the gaps of the display cabinet 1. Under the positive pressure environment, the dust diffuses out due to the pressure of the air flow and cannot enter the main frame, thus achieving dust-proofing while moisture-proofing. When the humidity and temperature sensor 35 detects that the external humidity is greater than the inside of the display cabinet 1 on rainy days, the controller 44 controls the fan 40 to stop blowing, and the moisture-proof function is performed by the drying box 42 inside the display cabinet 1. The inside of the drying box 42 is filled with silica gel desiccant. The silica gel particles have a porous structure and can physically adsorb moisture.

[0028] As a preferred embodiment, a timer 43 is provided on one side of the humidity and temperature sensor 35, and a controller 44 is provided on one side of the timer 43. The controller 44 is electrically connected to both the humidity and temperature sensor 35 and the timer 43. Spotlights 45 are provided on the tops of multiple display platforms 2. Among them, the timer 43 can be used to set the interval time for automatic cleaning, and the controller 44 automatically controls the start for cleaning, thereby realizing the function of automatic cleaning. The multiple spotlights 45 can irradiate the exhibits to improve the aesthetics.

[0029] The working process of this application is as follows: First, multiple display platforms 2 can be used to place and display the items to be displayed, and then they are protected by the transparent display door 3. The transparent display door 3 is made of transparent glass material, which is convenient for people outside the display cabinet 1 to observe and appreciate. The driving box 4 is specifically a trough-shaped body with an open side. Through the driving box 4, the lead screw 5 can be supported to rotate. The rotation of the lead screw 5 drives the moving block 6 to perform lifting and translational movements, so as to clean the transparent display door 3 in all directions up and down. When cleaning, the lifting of the moving block 6 can drive the driving rod 7 to move synchronously. The driving rod 7 drives the moving frame 10 and the display board 12 to perform synchronous lifting movements, so as to displace the cleaning pad 15 up and down. At the same time, the electric push rod 9 can push the moving frame 10 to perform translational movements in the horizontal direction, thereby driving the display board 12 to perform synchronous horizontal movements, so as to make the cleaning pad 15 close to the transparent display door 3, so as to better clean it. During the movement of the display board 12, the cleaning pad 15 can clean the surface of the transparent display door 3, preventing external dust from falling on the surface of the transparent display door 3 and affecting the display. During the cleaning process, the vibration motor 16 drives the connecting plate 14 and the cleaning pad 15 to vibrate. The high-frequency vibration can quickly decompose the dried water stains, oil stains, dust, etc. on the surface of the transparent display door 3, reducing the number of repeated wipes. Only by moving the cleaning pad 15 can the cleaning be completed. Through the micro water pump 20, the cleaning liquid in the water tank 18 can be pumped into the diversion pipe 19 and then diverted into the shunt pipe 21. During the cleaning process, the electric control valve 24 at the water inlet of the first nozzle 22 is opened, and the electric control valve 24 at the water inlet of the second nozzle 23 is closed. The cleaning liquid in the shunt pipe 21 is sprayed onto the surface of the transparent display door 3 through the first nozzle 22, cooperating with the cleaning pad 15 to clean the transparent display door 3 and ensuring the cleanliness of the display cabinet; The external air flow is blown into the interior of the display cabinet 1 by the blower 40. After the external dry air flow further absorbs moisture through the activated carbon filter layer 41, the dry and clean air flow is blown into the display cabinet 1, making its interior in a positive pressure environment. The air flow is discharged through the gaps of the display cabinet 1. Under the positive pressure environment, the dust diffuses outward due to the air flow pressure, so that it cannot enter the main frame, thus achieving the purpose of dust prevention. When the temperature and humidity sensor 35 detects that the external humidity is greater than the interior of the display cabinet 1 on rainy days, the blower 40 is controlled to stop blowing through the controller 44, and the moisture-proof function is performed by the drying box 42 inside the display cabinet 1. The inside of the drying box 42 is filled with silica gel desiccant. The silica gel particles have a porous structure and can physically adsorb moisture. The above is the working principle of this dust-proof and moisture-proof automatic cleaning display cabinet.
