Description

Technical Field

[0001] The present invention relates to the technical field of watering equipment, and particularly relates to a small automatic watering device. Background Art

[0002] With the continuous pursuit of the quality of life by humans, in daily life, people usually cultivate some potted flowers and plants they like in the courtyard to increase the joy of life. When taking care of the potted flowers and plants, watering needs to be carried out regularly. The traditional method is to manually water with containers such as buckets filled with water. This is rather laborious, and repeated water addition is required, with a large labor intensity and low efficiency. In addition, it is inevitable that people cannot water the flowers and plants on time due to water cut-off or other reasons in life. Once the time is delayed for too long, the normal growth of the flowers and plants will be affected. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention provides a small automatic watering device, which can replace manual watering, saving time and effort, having the functions of water storage, automatic water addition and water replenishment, and can avoid the problem that the normal growth of flowers and plants is affected due to failure to water on time.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A small automatic watering device includes a water tank. The inner cavity of the water tank is divided into a water addition cavity and a water storage cavity from top to bottom by a partition. A water addition pipe and an exhaust pipe extending into the water addition cavity are provided at the top of the water tank. A water replenishment pipe is provided at the bottom of the water addition cavity. After the water replenishment pipe extends out of the water tank, it is connected to the water storage cavity. A siphon tube is provided in the water storage cavity. After the siphon tube extends out of the water tank, it is connected to a watering cylinder. A water addition control mechanism for controlling the opening and closing of the water addition pipe, the exhaust pipe and the water replenishment pipe is provided in the water addition cavity. When the water addition control mechanism simultaneously opens the water addition pipe and the exhaust pipe, the water replenishment pipe is closed. When the water addition control mechanism simultaneously closes the water addition pipe and the exhaust pipe, the water replenishment pipe is opened. When the water addition pipe and the exhaust pipe are opened and the water replenishment pipe is closed, the water addition pipe is connected to an external water supply pipe to start adding water to the water addition cavity. During the water addition process, the water addition cavity exhausts air through the exhaust pipe. When the water in the water addition cavity is full, the water addition control mechanism simultaneously closes the water addition pipe and the exhaust pipe and opens the water replenishment pipe. The water addition cavity starts to replenish water to the water storage cavity. As the water replenishment and watering proceed, when the water in the water addition cavity is used up, the water addition control mechanism simultaneously opens the water addition pipe and the exhaust pipe and closes the water replenishment pipe, and then starts to add water to the water addition cavity, thereby realizing the functions of automatic water addition and water replenishment in a cycle.

[0006] Furthermore, ball valves are provided on both the water addition pipe and the exhaust pipe in the water addition cavity. A piston is provided at the pipe orifice of the water replenishment pipe in the water addition cavity. The water addition control mechanism controls the opening and closing of the water addition pipe and the exhaust pipe through the ball valves, and the water addition control mechanism controls the opening and closing of the water replenishment pipe through the piston.

[0007] Further, the water addition control mechanism includes a riser pipe disposed in the water addition cavity and a floating ball disposed in the riser pipe. When the floating ball floats to the top of the riser pipe, it opens the ball valve and drives the piston to block the water replenishing pipe. When the floating ball drops to the bottom of the riser pipe, it closes the ball valve and drives the piston to open the water replenishing pipe.

[0008] Further, an opening is provided on the side wall of the top of the riser pipe. The valve stem of the ball valve extends into the riser pipe through the opening. The water addition control mechanism further includes a first pulling rope and a second pulling rope disposed in the riser pipe. The valve stem of the ball valve is connected to the floating ball through the first pulling rope. The two ends of the second pulling rope are respectively connected to the piston and the valve stem of the ball valve on the water addition pipe.

[0009] Further, a slideway communicating with the riser pipe is provided on the side wall of the bottom of the riser pipe, and the piston is disposed in the slideway.

[0010] Further, the lower end of the riser pipe extends into the top of the water storage cavity, and the upper end of the riser pipe extends out of the top of the water tank.

[0011] Further, the water replenishing pipe and the water storage cavity are communicated through a water volume regulating mechanism. The water volume regulating mechanism includes a regulating box and a horizontal water storage cylinder. The water replenishing pipe is communicated with the side wall of the top of the horizontal water storage cylinder through a hose. One end of the horizontal water storage cylinder near the top of the horizontal water storage cylinder is provided with a water outlet pipe inserted into the water storage cavity. The regulating box is rotatably connected to the other end of the horizontal water storage cylinder for driving the horizontal water storage cylinder to incline. By adjusting the inclination degree of the horizontal water storage cylinder through the regulating box, the water volume replenished into the water storage cavity from the horizontal water storage cylinder is adjusted.

[0012] Further, a telescopic rod and a rotating rod are provided in the regulating box. A gear is provided on the rotating rod. The rotating rod extends out of the regulating box and is connected to a knob. One end of the telescopic rod is engaged with the gear, and the other end of the telescopic rod extends out of the regulating box and is rotatably connected to the top side wall of the end of the horizontal water storage cylinder far from the water outlet pipe.

[0013] Further, a plurality of water outlet holes are provided on the watering cylinder.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention divides the inner cavity of the water tank into a water addition cavity for storing water volume and a water storage cavity. The water stored in the water storage cavity is used for automatic watering through a siphon pipe and a watering cylinder. The water in the water addition cavity is used for replenishing water into the water storage cavity when the water in the water storage cavity cannot perform siphon. Finally, through the combined use of the water addition cavity and the water storage cavity, when the water supply is cut off or the water cannot be added into the water addition cavity on time due to other reasons, the water stored in the water addition cavity and the water storage cavity can be utilized first, playing an emergency role.

[0016] 2. During the use of the automatic watering device of the present invention, through the settings of the water filling pipe, the exhaust pipe, the water replenishing pipe and the water filling control mechanism, when the water in the water filling cavity is insufficient after watering, the water filling control mechanism opens the water filling pipe and the exhaust pipe, and closes the water replenishing pipe at the same time, thereby automatically stopping the water replenishment to the water storage cavity and starting to fill the water into the water filling cavity. When the water in the water filling cavity is full, the water filling control mechanism closes the water filling pipe and the exhaust pipe, and opens the water replenishing pipe at the same time, thereby automatically stopping the water filling and starting the water replenishment. Finally, through the cyclic automatic water filling and water replenishment, and combined with the siphon effect, automatic watering is realized, thus replacing manual watering, saving time and effort, being convenient and having high working efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0021] Embodiment 1

[0022] A small automatic watering device, as Figure 1 shown, includes a water tank 1. The inner cavity of the water tank 1 is divided into a water filling cavity 3 and a water storage cavity 4 from top to bottom by a partition board 2. A water filling pipe 5 extending into the water filling cavity 3 is fixed at the top of the water tank 1. The water filling pipe 5 is directly connected to an external water supply pipe. A siphon tube 11 is arranged in the water storage cavity 4. The siphon tube 11 extends out of the water tank 1 and is connected to a watering cylinder 12. A plurality of water outlet holes 26 are arranged on the watering cylinder 12. Both the water filling cavity 3 and the water storage cavity 4 can store a certain amount of water. Under the siphon effect, the water in the water storage cavity 4 is automatically discharged through the watering cylinder 12 for watering. As the water in the water storage cavity 4 decreases, the water in the water filling cavity 3 replenishes the water in the water storage cavity 4. When the water in the water filling cavity 3 is insufficient, the external water supply pipe fills the water into the water filling cavity 3 again.

[0023] Specifically, a water replenishing pipe 8 is fixed to the bottom of the water filling cavity 3. After the water replenishing pipe 8 extends out of the water tank 1, it is then communicated with the water storage cavity 4. Since air in the water filling cavity 3 needs to be discharged when adding water to the water filling cavity 3 to facilitate smooth water addition and filling of the water in the water filling cavity 3, an exhaust pipe 6 extending into the water filling cavity 3 is also fixed to the top of the water tank 1. In addition, ball valves 7 are installed on both the water inlet pipe 5 and the exhaust pipe 6 in the water filling cavity 3. The opening and closing of the water inlet pipe 5 and the exhaust pipe 6 are controlled by the opening and closing of the ball valves 7. A piston 10 is provided at the pipe orifice of the water replenishing pipe 8 in the water filling cavity 3. The pipe orifice of the water replenishing pipe 8 is blocked or opened by the piston 10, thereby realizing the opening and closing of the water replenishing pipe 8.

[0024] In order to improve work efficiency, realize the functions of automatic water addition and replenishment, and facilitate the control of the water addition and replenishment processes, a water addition control mechanism for controlling the opening and closing of the water inlet pipe 5, the exhaust pipe 6, and the water replenishing pipe 8 is provided in the water filling cavity 3 of this automatic watering device. The water addition control mechanism includes a riser pipe 13 provided in the water filling cavity 3, a floating ball 14 provided in the riser pipe 13, and a first pulling rope 16 and a second pulling rope 18 provided in the riser pipe 13. Specifically, an opening 15 is provided on the side wall of the top of the riser pipe 13. The valve stem of the ball valve 7 extends into the riser pipe 13 through the opening 15. The valve stem of the ball valve 7 is connected to the floating ball 14 through the first pulling rope 16. A slideway 17 communicated with the riser pipe 13 is fixed to the side wall of the bottom of the riser pipe 13. The piston 10 is provided in the slideway 17. The two ends of the second pulling rope 18 are respectively connected to the valve stem of the ball valve 7 on the piston 10 and the water inlet pipe 5.

[0025] Before watering, first fill the water addition chamber 3 and the water storage chamber 4 with water, and then start watering. As the water in the water storage chamber 4 decreases, the water addition chamber 3 gradually replenishes water to the water storage chamber 4. When the water in the water addition chamber 3 is used up, the floating ball 14 is located at the bottom of the riser pipe 13. At this time, the floating ball 14 presses against the piston 10 to block the water filling pipe 5, and the floating ball 14 pulls down the valve rod of the ball valve 7 through the first pull rope 16 to open the ball valve 7. The water in the water supply pipe will automatically flow into the water addition chamber 3 for water filling. During the water filling process, the air in the water addition chamber 3 is discharged until the water addition chamber 3 is full. As the water level in the water addition chamber 3 rises during water filling, the floating ball 14 will float to the top of the riser pipe 13. When the water is full, the floating ball 14 pushes upward against the valve rod of the ball valve 7 to rotate the valve rod of the ball valve 7 to close the ball valve 7, thereby stopping water filling. When the valve rod of the ball valve 7 rotates to close the ball valve 7, the valve rod of the ball valve 7 on the water filling pipe 5 pulls up the second pull rope 18, so that the piston 10 is pulled out of the water replenishing pipe 8 through the second pull rope 18 to open the water replenishing pipe 8 and start replenishing water to the water storage chamber 4 until the water in the water addition chamber 3 is used up and then starts to fill the water addition chamber 3 with water. Through the setting of the water filling control mechanism, when the water in the water addition chamber 3 is used up, the water filling pipe 5 and the exhaust pipe 6 are opened simultaneously and the water replenishing pipe 8 is closed, and then water starts to be filled into the water addition chamber 3; when the water in the water addition chamber 3 is full, the water filling pipe 5 and the exhaust pipe 6 are closed simultaneously and the water replenishing pipe 8 is opened, and then water starts to be replenished to the water storage chamber 4. By cycling in this way, the functions of automatic water filling and water replenishing are realized, thus replacing manual operation, reducing the workload and improving the work efficiency, making watering more convenient, time-saving and labor-saving.

[0026] Preferably, the lower end of the riser pipe 13 extends into the top of the water storage chamber 4, and the upper end of the riser pipe 13 extends out of the top of the water tank 1. The lengths of the lower end extending into the top of the water storage chamber 4 and the upper end extending out of the top of the water tank 1 are determined according to the actual situation, specifically, it can avoid that the floating ball 14 cannot open the ball valve 7 due to insufficient floating height and cannot press against the piston 10 due to insufficient descending height.

[0027] Embodiment 2

[0028] Due to the siphon effect, the water surface in the water storage chamber 4 needs to reach a certain height. When the water surface height in the water storage chamber 4 is insufficient, water needs to be replenished into the water storage chamber 4. The replenished water volume is the watering volume. Since different vegetation requires different watering volumes, it is necessary to adjust the replenished water volume according to different vegetation during water replenishment. Therefore, the automatic watering device of the present invention is connected to the water storage chamber 4 through a water volume adjustment mechanism installed at the water replenishing pipe 8 to adjust the replenished water volume into the water storage chamber 4 according to the actual situation, thereby avoiding excessive water replenishment from affecting the growth of vegetation.

[0029] Specifically, as Figure 2As shown in the figure, the water volume regulating mechanism includes a regulating box 19 and a horizontal water storage cylinder 9. The water supply pipe 8 is connected to the top side wall of the horizontal water storage cylinder 9 through a hose. When the water in the water filling cavity 3 is replenished into the water storage cavity 4, it will be stored in the horizontal water storage cylinder 9 first and then enter the water storage cavity 4 through the horizontal water storage cylinder 9. At one end of the horizontal water storage cylinder 9 near the top of the horizontal water storage cylinder 9, a water outlet pipe 21 inserted into the water storage cavity 4 is integrally formed. A telescopic rod 22 and a rotating rod 23 are provided in the regulating box 19. A gear 24 is fixed on the rotating rod 23. The rotating rod 23 extends out of the regulating box 19 and is connected to a knob 25. One end of the telescopic rod 22 is engaged with the gear 24. The other end of the telescopic rod 22 extends out of the regulating box 19 and is hinged to the top side wall of the end of the horizontal water storage cylinder 9 far from the water outlet pipe 21. In this way, by rotating the knob 25, the telescopic rod 22 can be driven to move up and down to realize the expansion and contraction of the telescopic rod 22, and then drive the horizontal water storage cylinder 9 to move to tilt it to different degrees. Since the water outlet pipe 21 is arranged near the top of the horizontal water storage cylinder 9, the amount of water replenished into the water storage cavity 4 through the horizontal water storage cylinder 9 can be controlled by adjusting the tilt degree of the horizontal water storage cylinder 9.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
