A water pump 10 is provided on the bottom inner wall of the water storage tank 8, and the water pump 10 is connected to one end of a drainage pipe 11, and the other end of the drainage pipe 11 is embedded in the inner wall of the sandbox outer frame 1. The outer wall of the drainage pipe 11 is provided with a branch, and the end of the branch is provided with an atomizing nozzle; the humidity monitoring sensor 4 is provided here to monitor the humidity inside the sandbox outer frame 1 in real time. When the humidity inside the sandbox outer frame 1 is high, the humidity monitoring sensor 4 will automatically control the power supply 5 to turn on. When the power supply 5 is turned on, the heating wire 6 will be automatically heated, and then the inside of the sandbox outer frame 1 will be automatically dried through heat transfer. When the humidity inside the sandbox outer frame 1 is low, the humidity monitoring sensor 4 will automatically control the water pump 10 to turn on. When the water pump 10 is turned on, the water inside the water tank 8 will be automatically pumped out, and then the water will be drained through the water inlet pipe 18 and finally sprayed out through the atomizing nozzle, so as to achieve the effect of increasing the humidity.

[0026] The automatic water storage replenishment mechanism includes a limit block 12, a limit rack 13, a limit gear 14 and a limit shaft 15. The outer wall of the water storage tank 8 is connected to one end of the limit block 12, and the other end of the limit block 12 is connected to the limit rack 13, and the limit rack 13 is arranged on the outside of the first limit box 2. The side of the limit rack 13 is meshed and connected with the limit gear 14, and the limit gear 14 is arranged on the outside of the limit shaft 15. One end of the limit shaft 15 is rotatably connected to the inner wall of the limit plate 16, and the other end of the limit shaft 15 is connected to the valve stem 17. The outside of the first limit box 2 is connected with a water inlet pipe 18, and the water inlet end of the water inlet pipe 18 is arranged in the first limit box 2, a valve is arranged inside the water inlet pipe 18, and the valve is connected to the valve stem 17; when the water inside the water storage tank 8 becomes less, the return spring 9 is squeezed by the water storage tank 8 and becomes smaller, and the water storage tank 8 will automatically move upward, and then the water storage tank 8 will automatically move upward to drive the limit block 12 to move and then drive the limit rack 13 to move, and when the limit rack 13 is engaged with the limit gear 14 during the movement, the limit gear 14 will automatically rotate to drive the limit shaft 15 to rotate and then drive the valve stem 17 to rotate, and then the valve stem 17 will automatically open the valve inside the water inlet pipe 18 when it rotates, so as to achieve the effect of automatic water storage.

[0027] The dust collection mechanism includes a dust suction pipe 19. The dust suction pipes 19 are symmetrically arranged on the inner walls at the bottom ends of both sides of the sandbox outer frame 1, and the outer walls of the dust suction pipes 19 are evenly spaced to open limiting holes 20.

When it is necessary to clean the dust inside the sandbox outer frame 1, the micro motor 21 needs to be turned on first. When the micro motor 21 is turned on, the fan 22 will automatically rotate. Since the fan 22 is reversely installed, suction will be generated when it rotates, so that the dust at the bottom end of the sandbox outer frame 1 is uniformly collected into the dust suction pipe 19 through the limiting holes 20, and then concentratedly collected into the second limiting box 3 through the obstruction of the filter plate 23.

[0028] Working principle of the utility model: The humidity monitoring sensor 4 is provided here to monitor the humidity condition inside the sandbox outer frame 1 in real time. When the humidity inside the sandbox outer frame 1 is high, the humidity monitoring sensor 4 will automatically control the power supply 5 to turn on. When the power supply 5 is turned on, the heating wire 6 will be automatically heated, and then the inside of the sandbox outer frame 1 will be automatically dried by heat transfer. When the humidity inside the sandbox outer frame 1 is low, the humidity monitoring sensor 4 will automatically control the water pump 10 to turn on. When the water pump 10 is turned on, the water inside the water tank 8 will be automatically pumped out, and then the water will be drained through the water inlet pipe 18 and finally sprayed out through the atomizing nozzle, so as to achieve the effect of increasing humidity. When the water inside the water tank 8 becomes less, the reset spring 9 will be squeezed by the water tank 8 and the force will become smaller, so it will automatically drive the water tank 8 upward. When the limit rack 13 is engaged with the limit gear 14 during movement, the limit gear 14 rotates and automatically drives the limit shaft 15 to rotate, thereby driving the valve stem 17 to rotate. Then, the valve stem 17 rotates and automatically opens the valve inside the water inlet pipe 18, thereby achieving the effect of automatic water storage. When it is necessary to clean the dust inside the sand table frame 1, the micro motor 21 needs to be turned on first. When the micro motor 21 is turned on, the fan 22 will be automatically driven to rotate. Since the fan 22 is installed in reverse, suction will be generated when it rotates, thereby collecting the dust at the bottom of the sand table frame 1 through the limit hole 20 to the inside of the dust suction pipe 19, and then collected to the inside of the second limit box 3 through the barrier of the filter plate 23.
