It should be noted that, referring to fig. 4, in order to reduce the possibility of water leakage of the water inlet cavity and enhance the sealing performance of the water inlet cavity, and further make the irrigation water more accurate, a plurality of water leakage preventing layers 8 are integrally formed and designed on the outer peripheral walls of the first rubber plug 502 and the second rubber plug 503. In this embodiment, the leakage-proof water layer 8 has three layers, and the diameters of the three layers of leakage-proof water layers 8 are slightly larger than the diameter of the communicating pipe 4, and are in a state abutting against the inner side wall of the communicating pipe 4 when the communicating pipe 4 is in the water supply system.

In one embodiment, referring to fig. 3 and 4, the driving assembly 501 includes a first lead screw 5011, a first motor 5013, a second lead screw 5012, and a second motor 5014, the first lead screw 5013 drives the first lead screw 5011 to rotate, the second lead screw 5014 drives the second lead screw 5012 to rotate, the communication tube 4 has a first inlet 9 and a second inlet 10, the first lead screw 5011 extends into the communication tube 4 through the first inlet 9, the second lead screw 5012 extends into the communication tube 4 through the second inlet 10, the first motor 5013 and the second motor 5014 are both located on the outer side wall of the communication tube 4, the first rubber plug 502 has a first through hole 11 and a second through hole 12, the second rubber plug has a third through hole 13 and a fourth through hole 14, the first lead screw 5011 extends through the first through hole 11 and the third through hole 13, the inner side wall of the first through hole 11 has threads matching with the first lead screw 5011, the second lead screw 5012 extends through the second through hole 12 and the fourth through hole 14, and the inner side wall of the fourth through hole 14 is provided with threads matched with the second screw 5012. In this embodiment, the first through hole 11 and the second through hole 12 on the first rubber plug 502, and the third through hole 13 and the fourth through hole 14 on the second rubber plug 503 are located on the diameter and have an equal distance from the circle center, the central axes of the first through hole 11 and the third through hole 13 are the same in the vertical direction, and the central axes of the second through hole 12 and the fourth through hole 14 are the same in the vertical direction. The first lead screw 5011 and the second lead screw 5012 are both longer than the communication pipe 4 and extend from the first motor 5013 and the second motor 5014 outside the communication pipe 4 to the position inside the conical piece 3 and higher than the smaller opening. Meanwhile, the first lead screw 5011 is integrally formed by the polished rod of the upper part and the screw of the lower part, and the second lead screw 5012 is integrally formed by the polished rod of the lower part and the screw of the upper part. Thus, the polish rod of the first lead screw 5011 does not control the third through hole 13 of the second rubber plug 503, and the second lead screw 5012 does not control the second through hole 12 of the first rubber plug 502.

When the automatic watering device 20 needs water, after the automatic watering device 20 is started, the control device 5 is driven to operate, the first lead screw 5011 and the second lead screw 5012 are driven to rotate under the combined action of the first driving piece and the second driving piece, so that the first rubber plug 502 and the second rubber plug 503 are lifted upwards to the same height and then stop, the first rubber plug 502 stops, the communication space between the communication pipe 4 and the spray conduit 6 can be isolated, the stop position of the second rubber plug 503 is positioned in the conical piece 3, the space between the conical piece 3 and the communication pipe 4 is communicated at the moment, after water in the liquid storage tank 2 enters the water cavity, the second rubber plug 503 descends by rotating the second lead screw 5012, after the communication space between the communication pipe 4 and the conical piece 3 is isolated, the fixed value of the water amount in the water cavity is obtained, then the first rubber plug 502 descends by rotating the first lead screw 5011, the inner spaces of the communication pipe 4 and the spray conduit 6 are communicated, the water flows into the shower pipe 6, and thus the requirement of supplying a constant amount of water to the automatic watering device 20 is fulfilled.

It should be noted that, when the water quantity needs to be changed, the height of the first rubber plug 502 in the communicating pipe 4, that is, the inner space of the water inlet chamber, needs to be controlled only in the lifting process.

It is worth mentioning that the abutting ring 15 is installed on the inner bottom wall of the communication pipe 4, the upper surface of the abutting ring 15 abuts against the first rubber plug 502, and the abutting ring 15 covers the first inlet 9 and the second inlet 10. The upper surface of the abutting ring 15 in this embodiment is provided with a layer of soft rubber, and when abutting against the first rubber plug 502, the abutting surfaces of the two rubber plugs can be more compact.

When having water and first plug 502 to slide down in the intracavity of intaking, through the setting of butt ring 15, can make the lower surface and the butt ring 15 looks butt of first plug 502, and not only there is the flexible glue to increase the compactness of both binding faces, and butt ring 15 surrounds first entry 9 and second entry 10, and then at the in-process of rivers to spray conduit 6, can prevent that water from flowing to first entry 9 or second entry 10 along the lower surface of first plug 502, lead to reacting with first motor 5013 or second motor 5014, damage controlling means 5.
