[0024] See also Figures 1 to 3The drip irrigation device for gardening provided by the utility model is now described. The drip irrigation device for gardening includes a water supply assembly 10, a drip irrigation head 20, a push rod 30, a guide rod 40 and an elastic member 50. The lower part of the water supply assembly 10 is provided with a water pipe 11 extending to one side; the drip irrigation head 20 is connected to the lower part of the water pipe 11 through a connecting pipe 21, the bottom of the drip irrigation head 20 is connected to a water outlet pipe 22, and the top of the drip irrigation head 20 is provided with an extension pipe 23 extending downward into the drip irrigation head 20, and the extension pipe 23 is arranged opposite to the water outlet pipe 22; the push rod 30 slides The push rod 30 is arranged in the extension tube 23, and can be moved downward and inserted into the water outlet pipe 22. The upper end of the push rod 30 is provided with a pressing platform 31 protruding toward the outer periphery; the guide rod 40 is connected to the top of the drip irrigation head 20 and is arranged to penetrate the pressing platform 31 upward, and the guide rod 40 and the pressing platform 31 are slidably matched; the elastic member 50 is sleeved on the outer periphery of the guide rod 40, and the upper end of the elastic member 50 is connected to the pressing platform 31, and the lower end is connected to the top wall of the drip irrigation head 20, and is used to elastically push the pressing platform 31 upward.

[0025] The embodiment of the present application provides a drip irrigation device for landscaping. In its actual use, the water supply assembly 10 is used to provide a water source for the drip irrigation head 20. When the water outlet pipe 22 is blocked, the pressing platform 31 can be pressed downward to move the push rod 30 downward and insert it into the water outlet pipe 22, thereby pushing the soil out of the water outlet pipe 22 to clear the water outlet pipe 22, thereby preventing the soil from entering the drip irrigation head 20 and improving the blockage clearing effect. After the pressing platform 31 is released, the elastic member 50 pushes the pressing platform 31 upward, and under the guidance of the guide rod 40, the pressing platform 31 drives the push rod 30 to return to the initial position, thereby preventing the push rod 30 from being in the water outlet pipe 22 for a long time and blocking the water outlet pipe 22.

[0026] Compared with the prior art, the drip irrigation device for landscaping provided in this embodiment, by pressing the pressing platform 31 downward, moves the push rod 30 downward and inserts it into the water outlet pipe 22, thereby pushing the mud out of the water outlet pipe 22 to clear the water outlet pipe 22, thereby preventing the mud from entering the drip irrigation head 20 and following the water flow to block the water outlet pipe 22 again, thereby improving the clearing effect.

[0027] In a possible implementation, the drip irrigation head 20 is as follows: Figures 1 to 3 The structure shown, see Figures 1 to 3 A partition plate 60 is provided in the drip irrigation head 20 between the connecting pipe 21 and the water outlet pipe 22 . A water hole 61 is penetrated through the partition plate 60 . The water hole 61 is located at the lower part of the partition plate 60 .

[0028] Specifically, there is a certain distance between the water hole 61 and the inner bottom wall of the drip irrigation head 20, so that after small-sized impurities enter the drip irrigation head 20 from the water outlet pipe 22, they follow the water flow and flow out of the water outlet pipe 22 again under the limitation of the partition plate 60, thereby preventing impurities from entering the side of the partition plate 60 close to the connecting pipe 21 and gradually accumulating, thereby preventing impurities from clogging the connecting pipe 21.

[0029] In some embodiments, see Figures 1 to 3 A one-way valve 70 for blocking the water hole 61 is rotatably connected to one side of the partition plate 60 close to the water outlet pipe 22 . The one-way valve 70 can swing vertically under the action of water pressure to open the water hole 61 .

[0030] Specifically, when water accumulates to a certain extent on the side of the partition plate 60 close to the connecting pipe 21, the one-way valve 70 can be squeezed open to allow water to enter the side of the partition plate 60 close to the outlet pipe 22 from the water hole 61. When the outlet pipe 22 is blocked, the one-way valve 70 prevents turbid water with impurities on the side of the partition plate 60 close to the outlet pipe 22 from entering the side of the partition plate 60 close to the connecting pipe 21, thereby preventing the connecting pipe 21 from being blocked to the greatest extent.

[0031] The one-way valve 70 is rotatably connected to the partition plate 60 via a rotating shaft. The rotating shaft is located at the upper portion of the one-way valve 70 and above the water passage hole 61 .

[0032] In some embodiments, see Figures 1 to 3 A receiving groove 62 for receiving the one-way valve 70 is provided on one side of the partition plate 60 close to the water outlet pipe 22 , and a sealing ring 63 located on the outer periphery of the water passing hole 61 is embedded on the bottom wall of the receiving groove 62 , and the sealing ring 63 is used to abut and cooperate with the one-way valve 70 .

[0033] Specifically, when the one-way valve 70 is in a closed state, the side wall of the one-way valve 70 close to the partition plate 60 fits tightly against the sealing ring 63 , thereby enhancing the airtightness and preventing turbid water with impurities from entering the side of the partition plate 60 close to the connecting pipe 21 .

[0034] In some embodiments, see Figure 1 and Figure 2 A piston 80 is sleeved on the outer peripheral wall of the push rod 30 and abuts against the inner peripheral wall of the extension tube 23 . The piston 80 is locked by a locking member 90 .

[0035] Specifically, the partition plate 60 is defined to separate the drip irrigation head 20 into a water storage chamber and a water outlet chamber, the extension tube 23 is located in the water outlet chamber, the water outlet tube 22 is connected to the water outlet chamber, and the connecting tube 21 is connected to the water storage chamber. The piston 80 is in abutment with the inner peripheral wall of the extension tube 23 and can move along the axial direction of the extension tube 23 under the drive of the push rod 30, which can not only prevent the water in the drip irrigation head 20 from overflowing from the extension tube 23, but also can make the push rod 30 drive the piston 80 to move downward when the water outlet tube 22 is blocked to increase the pressure in the water outlet chamber, and cooperate with the one-way valve 70 to always be in a closed state under the pressure in the water outlet chamber to ensure stable pressure increase in the water outlet chamber, so that the mud in the water outlet tube 22 is pushed out of the water outlet tube 22 under the pressure in the water outlet chamber and the push rod 30, thereby improving the cleaning effect.

[0036] In some embodiments, see Figure 1 and Figure 2 A limit platform 32 is provided on the outer peripheral wall of the push rod 30, which protrudes toward the outer periphery and is located above the piston 80. The locking piece 90 is threadedly sleeved on the outer periphery of the push rod 30 and is located below the piston 80. The locking piece 90 can axially push the piston 80 to abut against the limit platform 32 to lock the axial position of the piston 80.

[0037] Specifically, the axial displacement of the piston 80 is limited by the upper and lower limit cooperation of the locking member 90 and the limit platform 32, so that the piston 80 can stably move up and down following the push rod 30, and when the piston 80 needs to be replaced, it is only necessary to pull out the push rod 30 and disassemble the locking member 90 for replacement, thereby improving practicality.

[0038] In a possible implementation, the water supply assembly 10 is configured as follows: Figure 1 The structure shown, see Figure 1 The water supply assembly 10 includes a mixing tank 12 and a stirring member 14. The mixing tank 12 is used to contain a mixed liquid. A liquid inlet pipe 13 is provided on the top of the mixing tank 12. The water guide pipe 11 is connected to the lower part of the mixing tank 12. The stirring member 14 is rotatably connected to the top of the mixing tank 12 and extends downward into the mixing tank 12 for stirring the mixed liquid.

[0039] Specifically, water and agents required for plant growth are often added into the mixing tank 12 through the liquid inlet pipe 13 so that they are uniformly mixed into a mixed liquid under the stirring of the stirring element 14, thereby accelerating the mixing rate and improving the mixing effect.

[0040] When no medicine is added, the stirring element 14 may not be used.

[0041] In some embodiments, see Figure 1The stirring member 14 includes a disturbance shaft 142 and a paddle 143. The disturbance shaft 142 is rotatably connected to the top of the mixing tank 12 and extends downward into the mixing tank 12. The upper end of the disturbance shaft 142 is connected to a rotating drive member 141, and the rotating drive member 141 is located above the mixing tank 12; the paddle 143 is connected to the outer periphery of the disturbance shaft 142 for stirring the mixed liquid.

[0042] Specifically, when water and the medicine required for plant growth enter the mixing tank 12, the rotating drive member 141 drives the disturbance shaft 142 to rotate, so that the paddle 143 stirs the mixed liquid in the mixing tank 12 to accelerate the mixing. The setting of the rotating drive member 141 can accurately control the stirring rate and avoid the tedious process of manual stirring.

[0043] In some embodiments, see Figure 1 The outer end of the paddle 143 extends obliquely outward and downward.

[0044] Specifically, the blades 143 stir the mixed liquid, which speeds up the uniform mixing efficiency of the mixed liquid and improves the mixing effect. The blades 143 extending obliquely downward increase the disturbance depth of the blades 143, and at the same time, the number of blades 143 can be reduced, thereby reducing the use cost.

[0045] In a possible implementation, the water conduit 11 is as follows: Figure 1 The structure shown, see Figure 1 A water pump 111 is provided on the water conduit 11 , and the water pump 111 is located between the water supply assembly 10 and the connecting pipe 21 .

[0046] Specifically, a plurality of drip irrigation heads 20 are arranged at intervals along the direction of the water pipe 11 . The water pump 111 can pump water in the water supply assembly 10 into the drip irrigation head 20 , thereby increasing the conveying efficiency and avoiding the situation where the conveying power is insufficient due to the excessive length of the water pipe 11 .

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
