Description

Technical Field

For example, the unpowered automatic watering device submitted in the patent application with announcement number CN208708334U can be referred to.

[0003] However, the unpowered automatic irrigation device still has the following defects and shortcomings during use:

[0004] 1) Due to its own structural reasons, after a single irrigation, when the buoyancy of the water in the lower cavity is insufficient to float the second float 11, the second valve plate 16 cannot be opened, so that the irrigation liquid cannot be discharged from the instantaneous irrigation port 6, so that a lot of water will still remain in the lower cavity and cannot be discharged.

[0005] 2) When the liquid level in the lower cavity of the unpowered automatic watering device is high, the flap gate is fully open and the watering flow is very large. When the liquid level is low, the flap gate is close to closing and the watering flow becomes very small. If there are multiple points of watering outside, the watering flow is unstable and the watering effect is poor.

[0006] Therefore, there is an urgent need to provide a non-powered siphon irrigation device to improve and optimize the defects and shortcomings in the above-mentioned prior art. Utility Model Content

[0032] [First embodiment]

[0033] like Figure 1-7 The figure shows a non-powered siphon irrigation device provided by the first embodiment of the utility model. Figure 1 As shown, it includes a shell 1, and the interior of the shell 1 is formed with an upper cavity A and a lower cavity B. Figure 1 As shown, as one of the preferred embodiments, a bracket 11 is provided in the middle of the shell 1, and the upper cavity A is supported on the top of the lower cavity B through the bracket 11.

[0034] like Figure 1As shown, a liquid inlet 2 is provided at the top of the housing 1, and the irrigation liquid can enter the housing 1 at a uniform speed through the liquid inlet 2, so as to achieve uniform and stable discharge of the irrigation liquid. An overflow port 3 and a water replenishment component are provided inside the upper cavity A, and the upper cavity A can be connected to the lower cavity B through the overflow port 3 and the water replenishment component. A float component and an irrigation pipe 10 are provided inside the lower cavity B. The float component is connected to the water replenishment component to control the opening and closing of the water replenishment component, and the irrigation pipe 10 uses a siphon tube, and the water inlet of the irrigation pipe 10 is located inside the lower cavity B, and the water outlet of the irrigation pipe 10 extends out of the housing 1. On the one hand, by providing an irrigation pipe to replace the second buoyancy valve device of the prior art, and by providing the irrigation pipe as a siphon pipe, since there is no need for buoyancy to drive the valve to open, and the water inlet of the siphon pipe extends into the liquid level of the lower cavity, the lower cavity can be basically emptied. Therefore, under the condition of the same irrigation amount, the irrigation device can be miniaturized and lightweight. On the other hand, by providing an irrigation pipe to replace the second buoyancy valve device of the prior art, and by providing the irrigation pipe as a siphon pipe, the water inlet of the siphon pipe can discharge the irrigation liquid as long as it extends into the liquid level of the lower cavity, the irrigation water flow rate changes little, and the irrigation effect is good. Correspondingly, in order to achieve the siphon effect, it is necessary to ensure that the water inlet height of the irrigation pipe 10 is higher than the water outlet height.

[0035] like Figure 1 As shown, the water replenishment assembly includes a water replenishment hole 4 opened at the bottom of the upper cavity A and connected to the lower cavity B, a flap door 5 is hinged at the top of the water replenishment hole 4, and the end of the flap door 5 away from the hinge point is connected to one end of the pull rope 6; and the float assembly includes a slide rod hole 7 opened at the bottom of the upper cavity A and connected to the lower cavity B, a slide rod 8 is slidably connected inside the slide rod hole 7, one end of the slide rod 8 is connected to the other end of the pull rope 6, and the other end of the slide rod 8 is fixedly connected to a float 9, and the float 9 is located inside the lower cavity B and can rise and fall synchronously with the liquid level inside the lower cavity B. This arrangement makes it possible that: when the float 9 can rise and fall synchronously with the liquid level inside the lower cavity B, it drives the slide rod 8 to rise and fall synchronously inside the slide rod hole 7, so that the flap door 5 is synchronously pulled or released around the hinge point by stretching 6 at the top of the slide rod 8, thereby realizing the opening and closing of the flap door 5.

[0036] As a further preference of this embodiment, the height of the water replenishment hole 4 is lower than the height of the overflow port 3, so that when the liquid level inside the upper cavity A is too high, it can preferentially flow into the lower cavity B through the water replenishment hole 4; at the same time, the height of the slide rod hole 7 is greater than the height of the overflow port 3, so as to avoid the pouring liquid from unexpectedly entering the slide rod hole 7 when the liquid level inside the upper cavity A is too high.

[0037] In addition, the flap door 5 is further inclined at the top of the water supply hole 4 to control the opening and closing of the water supply hole 4, so that when the flap door 5 is closed, the flap door 5 can rely on its own gravity to close the water supply hole 4 tightly, reducing the possibility that the flap door 5 cannot be completely closed due to failure to align with the water supply hole 4.

[0038] Since the present embodiment replaces the second buoyancy valve device of the prior art by providing an irrigation pipe, and the irrigation pipe is provided as a siphon pipe, the water inlet of the siphon pipe can discharge the irrigation liquid as long as it extends into the liquid level of the lower cavity, and the irrigation water flow rate changes little. Therefore, the single irrigation amount of the unpowered siphon irrigation device can be controlled by changing the volume of the upper cavity A and the lower cavity B, and the irrigation cycle of the unpowered siphon irrigation device can be controlled by changing the liquid inlet flow rate of the liquid inlet 2.

[0039] The specific working process of this embodiment is:

[0040] The liquid used for irrigation flows into the upper cavity A through the water inlet 2. Figure 2 As shown; the liquid level in the upper cavity A gradually rises, and after it passes the overflow port 3, the liquid enters the lower cavity B through the overflow port 3. Figure 3 As the irrigation liquid enters, the liquid level inside the lower cavity B gradually rises, and the float 9 rises slowly and synchronously under the action of buoyancy, and drives the top slide bar 8 to rise synchronously inside the slide bar hole 7, and starts to pull the pull rope 6. At this time, Figure 4 As the float 9 continues to rise slowly, the flap door 5 also begins to be opened, at this time Figure 5 As shown, after the flap door 5 is opened, the liquid enters the lower cavity B through the water replenishment hole 4, the liquid level inside the lower cavity B rises faster and quickly submerges the irrigation pipe 10, and the irrigation pipe 10 forms a siphon, water enters the lower cavity B from the water inlet, and quickly drains to the outside through the water outlet. At this time, the flap door 5 is opened to the maximum opening, as shown in FIG. Figure 6 As shown; when the water inlet 2 stops flowing, the liquid level in the lower chamber B drops, driving the slide bar 8 and the stretching 6 to drop synchronously, and the flap door 5 falls due to its own gravity to close the water supply hole 4. At this time, Figure 7 As shown, the irrigation process is finished.

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
