Technical Field

[0001] The utility model belongs to the technical field of seedling cultivation, and particularly relates to a low-pressure watering device. Background Art

[0002] Low-pressure watering devices are used for watering vegetation cultivation, such as the cultivation of seedlings. Existing methods for humidifying the seedling tray mostly use sprinkler irrigation to humidify the soil. As the seedlings continue to grow, the distance between the seedlings and the sprinkler gradually decreases, resulting in the water being unable to completely penetrate the soil in the spray state, so that the roots of the seedlings cannot absorb water well. At the same time, the existing humidification watering device needs to increase the pressure of the sprinkler head to achieve fluid spraying. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0022] The following combination Figure 1-5 The present invention is described in detail in a specific embodiment. A low-pressure watering device includes a fluid delivery pipe 1, wherein a fluid cavity 11 is formed within the fluid delivery pipe 1. The fluid delivery pipe 1 is used to deliver fluid for drip irrigation of seedlings, which can be used to fertilize or moisturize the seedlings. The fluid delivery pipe 1 is provided with a plurality of fluid drippers 2, which are in communication with the fluid cavity 11, and whose water inlet ends extend into the fluid stored in the fluid cavity 11. The fluid drippers 2 deliver the fluid stored in the fluid cavity 11 under low pressure, thereby delivering fluid to the seedlings. In some embodiments, the number of fluid drippers 2 can be any number, and the distance between each dripper can be adjusted based on the actual needs of the seedling cultivation. In this embodiment, the number of fluid drippers 2 is multiple, and the plurality of fluid drippers 2 are evenly spaced along the length of the fluid delivery pipe 1, achieving uniform fluid delivery to different sections of the seedling tray. The fluid is delivered to the seedlings in the tray under low pressure, and the fluid drips along the seedlings onto the soil.

[0023] Please refer to Figure 1-2 As shown, fluid input ports 13 are formed at both ends of the fluid delivery tube 1, and plugs 12 are provided on the fluid input ports 13. The plugs 12 are detachably connected to the fluid delivery tube 1. Fluid input ports 13 are formed at both ends of the fluid delivery tube 1, and fluid can be input into the fluid cavity 11 through the fluid input ports 13 to ensure uniform output of fluid from multiple fluid drippers 2.

[0024] In the first embodiment of the fluid dripper 2

[0025] Please refer to Figure 1 、 3As shown in Figure 4, the fluid dripper 2 is a direct current dripper 21, which includes a first sealing plug 212, which is installed and connected to the fluid delivery pipe 1, and a cavity tube 211 is sleeved in the first sealing plug 212, and the cavity tube 211 extends to the inside of the fluid cavity 11 and is connected to the fluid cavity 11. A first drip nozzle 213 is installed at the bottom of the first sealing plug 212, and the first drip nozzle 213 is connected to the fluid cavity 11 through the first sealing plug 212. The direct current dripper 21 is provided at the lower end of the fluid delivery pipe 1, wherein the amount of water filled in the fluid cavity 11 needs to cover the upper end surface of the cavity tube 211, and the water level difference and the pressure difference formed by the water level difference can force the air to squeeze the fluid to flow out from the end of the first drip nozzle 213.

[0026] Please refer to Figure 2 As shown, the liquid level stored in the fluid cavity 11 is higher than the installation height of the cavity tube 211 in the fluid cavity 11. By controlling the input of the fluid, the liquid level stored in the fluid cavity 11 is controlled to ensure the output of the fluid.

[0027] In the second embodiment of the fluid dripper 2

[0028] Please refer to Figure 4 As shown, the fluid dripper 2 is a curved tube dripper 22, which includes a second sealing plug 222, which is installed and connected to the fluid delivery pipe 1. A fluid output pipe 221 is sleeved inside the second sealing plug 222, and one end of the fluid output pipe 221 forms a water outlet, and the other end extends to the top of the fluid cavity 11. The curved tube dripper 22 is installed on the top of the fluid delivery pipe 1 to squeeze and discharge the fluid in the fluid cavity 11 upward. The fluid output pipe 221 is installed and connected to the fluid delivery pipe 1 through the second sealing plug 222, so that the fluid in the fluid cavity 11 is discharged through the fluid output pipe 221.

[0029] Please refer to Figure 5 As shown, a second drip nozzle 223 is provided at one end of the second sealing plug 222 away from the elbow dripper 22 , and the second drip nozzle 223 is communicated with the fluid output pipe 221 and the fluid cavity 11 respectively.

[0030] Please refer to Figure 5 As shown, the fluid stored in the fluid cavity 11 fills the fluid cavity 11 , wherein the liquid level stored in the fluid cavity 11 basically fills the fluid cavity 11 , and the fluid input pressure at both ends of the fluid delivery tube 1 is used to press the fluid in the fluid cavity 11 out.

[0031] Working principle of this utility model:

[0032] Connect both ends of the fluid delivery pipe 1 to a fluid storage tank, which can store, for example, water, a fertilizer solvent, or other insecticide solvents;

[0033] In the first embodiment of the fluid dripper 2, fluid is input into the fluid cavity 11 so that the liquid level of the fluid in the fluid cavity 11 is submerged above the upper end surface of the cavity tube 211. Under the action of gravity difference and the pressure difference formed by the gravity difference, the fluid is pressed out through the cavity tube 211 and the first drip nozzle 213, without the need for additional pressurizing equipment to increase the pressure in the fluid cavity 11.

[0034] In the second embodiment of the fluid dripper 2, by filling the entire fluid cavity 11 with the solvent, the fluid in the fluid cavity 11 can achieve uniform outflow of the fluid without the need for pressure. After being squeezed out, the fluid drips onto the seedlings and then drips onto the soil on the seedling tray, which facilitates the absorption of water by the roots of the seedlings and ensures the normal growth of the seedlings.

[0035] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0036] The above content is merely an example and explanation of the structure of the present utility model. Technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner.
