The utility model discloses an environmental climate box with a low
water level alarm function. The environmental climate box comprises an outer box body and a box door hinged to the outer box body. A
water storage tank is mounted on the inner side of the outer box body, a water inlet is formed in the top of the
water storage tank, and a display screen is mounted on the front side of the
water storage tank; a low-water-level early warning structure is arranged on the inner side of the
water storage tank, the early warning structure comprises a
buoyancy plate, and a limiting plate is mounted on the inner wall of the bottom of the
water storage tank; a limiting rod is installed on the inner wall of the top of the
water storage tank, and a water pump is arranged on the outer side of the water
storage tank. According to the environmental climate box with the low-water-level alarm function, a first through hole is formed in a
buoyancy plate, a sealing plug is installed on the upper surface of the
buoyancy plate and made of rubber, and the outer
diameter of the sealing plug is equal to the inner
diameter of a water inlet, so that when the buoyancy plate ascends and descends, the sealing plug is driven to ascend and descend together, the water inlet is blocked through the sealing plug, and the water inlet is prevented from being blocked. And therefore, the phenomenon of water overflow caused by excessive water addition is effectively prevented.
