## Abstract

The disclosed device includes a water storage container, an evaporation cover, a funnel, an indicator rod and a float. The water storage container has an evaporation cover. The evaporation cover is a gas permeable structure. A funnel is connected to the evaporation cover and an indication is provided in the leakage tube of the funnel. A rod. A float is connected to the lower end of the indicator rod and the float drives the indicator rod to indicate the water level in the water storage container. The method is as follows: the water storage container and the evaporation cover are buried in the soil of the plant root, and the water is filled into the water storage container through the funnel. The water in the water container naturally evaporates into the soil through the evaporation hood, which maintains the water in the soil to maintain the survival of the plant.

## Claims

### Claim 1

A device for aiding plant survival, the device comprising: a first water storage container, an evaporation cover, a funnel, an indicating rod and a float, wherein: the first water storage container is used for storing water, the first water storage container has the evaporation cover on top, the evaporation cover has a gas permeable structure, and the evaporation cover is connected to the funnel, the indicator rod is arranged in a leak tube of the funnel, a gap exists between the leak tube of the funnel and the indicator rod; a lower end of the indicator rod extends to the first water storage container and is connected with a float; the float drives the indicator rod to indicate a water level inside of the first water storage container,
wherein the funnel has an inner thread buckle, the funnel with the inner thread buckle is provided with a filter tower, the outer end of the filter tower has an outer thread buckle, the filter tower has a filter hole at the upper end and the indicator rod passes through the hole; the funnel passes through a conduit and the evaporating cover is connected, and the lower end of the conduit is connected with an elbow; the other end of the elbow has a backstop on the water outlet, and after stopping the water injection, the water outlet is blocked to prevent the water in the first water storage container from evaporating to the atmosphere along the conduit; the elbow includes a through hole for receiving the indicator rod, and the indicator rod is connected to the float.

### Claim 2 (depends on 1)
