Summary of the invention
The objective of the invention is to overcome the weak point of prior art, and a kind of water container of the plant cultivation apparatus that can be automatically water container be supplied water is provided.
A kind of water container of plant cultivation apparatus comprises water tank, and its structural feature is: the bottom of water tank is provided with water inlet; This water inlet is communicated with the water source, and water inlet is provided with water intaking valve, in water tank, is provided with a ball float; Above water inlet, be provided with a lever; Lever is supported in the water tank, and ball float and water intaking valve are divided into the two ends of lever, and the drive unit of water intaking valve is articulated on the lever.
The water container of the plant cultivation apparatus of this structure is provided with water intaking valve through the water inlet at water tank, and water intaking valve is passed through lever and ball float interlock, like this water level step-down in water tank; The ball float dehydration descends, and the lever that drives the ball float side presses down, and makes the lever of opposite side upwarp, and the water intaking valve that the lever that upwarps then drives side moves; From water inlet, when water intaking valve separates with water inlet, water will get into water tank by water inlet with its band, when the water that gets into water tank acquires a certain degree; Hold up ball float, make the lever of ball float side rise, the lever of opposite side presses down; The lever drives water intaking valve that presses down presses down, and covers water inlet, thereby stops the water supply to water tank.Therefore the container of plant cultivation apparatus of the present invention can be realized the automatic water-supply to the plant cultivation water tank.
The structure of described water intaking valve has a lot, below is several kinds of forms that the applicant provides:
A kind ofly be: described water intaking valve is the valve gap that is placed on the water inlet.
Another kind is: described water intaking valve is a piston of filling in water inlet.
Hinged for offering the through hole that the drive unit that can supply water intaking valve slides within it along the axis direction of lever between the drive unit of described water intaking valve and the lever, also be provided with on the drive unit of water intaking valve the restriction drive unit move up and down with respect to the through hole on the lever distance on keeper and following keeper.
Described upper and lower keeper or for to be arranged at the backstay on the water intaking valve drive unit, or be positioning convex.
Described drive unit is the driving rod that is fixed on the water intaking valve, itself or with water intaking valve be integral structure, or be being connected of movable detachable with water intaking valve.
Ball float being set on lever, or be movable detachable being connected with lever, or for being fixedly connected.
Can also the structure of ball float and lever being processed integral type between ball float and the lever.
Described ball float is the goblet of reverse buckling type, or orbicule, or cover-shaped body.
In sum, the present invention compares the following advantage of prior art:
The present invention introduces the water intaking valve structure by ball float, lever control in the water tank of the water container of plant cultivation apparatus, drive the up-down of the water intaking valve that is positioned at the lever other end through the up-down of ball float, thereby realizes the automatic water inlet of the water container of this plant cultivation apparatus.
Embodiment
Below in conjunction with embodiment the present invention is described in more detail.
Embodiment 1
A kind of water container of the plant cultivation apparatus shown in Fig. 1-2 comprises water tank 1, and the bottom of water tank is provided with water inlet 11; This water inlet is communicated with the water source, and water inlet is provided with water intaking valve 12, in water tank, is provided with a ball float 13; Above water inlet, be provided with a lever 14; Lever is supported in the water tank, and ball float and water intaking valve are divided into the two ends of lever, and the drive unit of water intaking valve is articulated on the lever.Described water intaking valve is a piston of filling in water inlet.The drive unit of water intaking valve is a driving rod 15; Driving rod and water intaking valve are the structure of integral type; Hinged for offering the through hole 16 that the drive unit that can supply water intaking valve slides within it along the axis direction of lever between driving rod and the lever, also be provided with on the drive unit of water intaking valve the restriction drive unit move up and down with respect to the through hole on the lever distance on keeper and following keeper 151.Described upper and lower keeper is the backstay that is arranged on the drive unit.Ball float and lever are for processing integral structure.Ball float is the goblet of reverse buckling type.
It is identical with prior art that present embodiment is not stated part.
