The lower end of the water reservoir 42 is provided with a water outlet hole 421 for connecting the water pipe 37.
However, if the water reservoir 42 is in a normally open state, when the sealing property between the pressing plate 321 and the first receiving cavity 311 is insufficient, the water reservoir 42 always supplies water, which may cause water to continuously overflow from the gap between the pressing plate 321 and the first receiving cavity 311, resulting in water waste, and also may not realize long-term independent self-supply. Based on the above problem, the outlet hole 421 is located at the lowest position of the water reservoir 42, a sealing member 43, such as a sealing ball, is further disposed in the water reservoir 42, the density of the sealing member 43 is slightly greater than that of water, the sealing member can sink to the outlet hole 421 of the water bottom, and when the sealing member 43 blocks the outlet hole 421, the sealing member plays a role in sealing the outlet hole 421. The above structure can cause the fluid pressure in the first receiving chamber 311 to increase when the pressing plate 321 acts downwards, and by controlling the height of the water reservoir 42, the fluid in the first receiving chamber 311 can impact the sealing member 43 upwards along the water pipe 37, so that the sealing member 43 is flushed away from the water outlet hole 421, and the water reservoir 42 can continuously supply water to the first receiving chamber 311 before the sealing member 43 falls on the water outlet hole 421 again. Further, in order to prolong the time that the sealing member 43 falls on the water outlet hole 421 again, the inner wall of the water storage device 42 is provided with the delay plate 422, the delay plate 422 is inclined, so that the sealing member 43 can move downwards along the delay plate 422, and the time that the sealing member 43 falls on the water outlet hole 421 can be further prolonged according to the inclination degree of the delay plate 422, so as to meet the time requirement of water replenishing operation.
In addition, in order to reduce the evaporation of water from the water reservoir 42, the end cover 423 of the water reservoir 42 is in a closed state and is activated to be opened only in rainy weather. Specifically, the end cover plate 423 is hinged at one end, the container 44 can contain rainwater by arranging the container 44 outside the water reservoir 42, the container 44 and the end cover plate 423 are connected by arranging a set of levers, the container 44 is gradually weighted due to the containing of rainwater in rainy days, so that the levers start to incline, and after the conversion of the lever set, the end cover plate 423 is opened. It should be noted that the outer drainage holes 441 are disposed on the container 44 to drain internal rainwater, so that after the rain stops, the weight of the container 44 is continuously reduced, and the container 44 cannot maintain the open state of the end cover plate 423 due to the reduction of weight, so that the end cover plate 423 is reset and closed again under the action of the reset piece 426.
