Description

Technical Field

[0001] The utility model relates to the technical field of gardening and garden irrigation, in particular to a water dripper. Background Art

[0002] Plants need to be supplied with water regularly and quantitatively within a certain period of time to avoid withering. Native plants have huge roots, which can absorb water from the soil in the natural ecology, or rely on natural rainwater to survive. However, because of potted plants and their inherent characteristics, domestic plants, vegetables or some delicate flowers and plants have more stringent maintenance conditions and require targeted care. In the past, a large amount of watering at one time would cause the soil to harden and suffocate the roots, so people developed drip irrigation, which can continuously moisten the soil in small amounts and is also very friendly to people who are away from home for short-term travel. Existing drippers mainly achieve this type of drip irrigation, but there are some problems, such as:

[0003] The interface of the dripper to connect to the water source has poor adaptability and can only be connected to a bottle with a single caliber;

[0004] The ability of the dripper to remove external impurities is not strong. Some drippers have exposed water sources and are easily blocked by external impurities or fallen leaves. Utility Model Content

[0005] In view of the above-mentioned defects of the prior art, the purpose of the present utility model is to provide a water dripper.

[0006] The technical solution of the utility model is: a water dripper, comprising a water tank, a top cover fixedly connected to the outside of the water tank, a joint sleeved on the upper end of the top cover and a dripping head threadedly connected to the bottom of the water tank, the lower end of the water tank is provided with a ground plug extending up and down, the joint is connected up and down, the joint, the top cover, the water tank, and the dripping head are connected in sequence from top to bottom, the lower end of the dripping head is provided with a dripping hole opening downward, the outer wall of the joint is provided with a plurality of circular steps with different outer diameters, and the outer diameter of each step gradually increases from top to bottom.

DETAILED DESCRIPTION

[0021] In order to more intuitively and completely understand the technical solution of the utility model, the following non-limiting feature description is now provided in conjunction with the accompanying drawings of the utility model:

[0022] like Figure 1 — Figure 4As shown, the dripper includes a water tank 1, a top cover 2 fixedly connected to the outside of the water tank 1, a joint 3 sleeved on the upper end of the top cover 2, and a drip head 4 threadedly connected to the bottom of the water tank 1, the lower end of the water tank 1 is provided with a ground plug 5 extending up and down, the joint 3 is passed through up and down, the joint 3, the top cover 2, the water tank 1, and the drip head 4 are connected in sequence from top to bottom, the lower end of the drip head 4 is provided with a drip hole 41 with an opening facing downward, and the outer wall of the joint 3 is provided with a plurality of circular steps 31 with different outer diameters, and the outer diameter of each step 31 gradually increases from top to bottom.

[0023] like Figure 3 As shown, in order to facilitate the disassembly and assembly of the water tank 1, the water tank 1 is fixed to the top cover 2 by means of a threaded connection, and a sealing ring 6 is clamped between the upper end of the water tank 1 and the inner wall of the top cover 2.

[0024] like Figure 3 and Figure 4 As shown, the top cover 2 has a stepped column 21 at the middle of the upper end, the joint 3 is sleeved outside the stepped column 21, and the joint 3 has a stepped hole 32 inside for the stepped column 21 to be inserted into. The outer wall of the stepped column 21 fits tightly with the inner wall of the stepped hole 32, so that the joint 3 is connected to the top cover 2 more firmly, and a stable joint 3 can better connect the water bottle.

[0025] like Figure 3 and Figure 4 As shown, the outer edge of the bottom of the water tank 1 has a downwardly protruding water outlet pipe 11, the water outlet pipe 11 is connected with the water tank 1 and the drip head 4, the outer wall of the water outlet pipe 11 has an external threaded portion 111, and the drip head 4 has a threaded hole 42 with an opening facing upward and for the external threaded portion 111 to be screwed in. The water outlet pipe 11 has a guide hole 112, and the drip head 4 has a blocking column 43 extending up and down, the guide hole 112 is for the blocking column 43 to extend into, and the outer diameter of the blocking column 43 gradually increases from top to bottom. The drip head 4 has a water outlet hole 44 in the middle position, the water outlet hole 44 is located below the blocking column 43, and the water outlet hole 44 is connected with the drip hole 41. The outlet pipe 11 also has a first through hole 113 and a second through hole 114. The first through hole 113, the guide hole 112, and the second through hole 114 are connected in sequence from top to bottom. The first through hole 113 is connected to the water tank 1, and the second through hole 114 is connected to the outlet hole 44 of the drip head 4. The inner diameters of the first through hole 113 and the second through hole 114 are larger than the inner diameter of the guide hole 112. The drip head 4 can be moved upward by rotating it forward and reversely, so that the blocking column 43 can be moved up and down, that is, the position of the blocking column 43 extending into the guide hole 112 can be adjusted. The more the blocking column 43 moves upward, the smaller the gap between the outer wall of the blocking column 43 and the inner wall of the guide hole 112 will be, and the less water can pass through. The water outlet rate is adjusted by changing the water flow rate, so the dripping rate can be regulated by rotating the drip head 4.

[0026] like Figure 2As shown, the ground plug 5 is a semi-enclosed structure, the bottom of which is sharp, and there are reinforcing ribs 51 inside the ground plug 5. The ground plug 5 of the semi-enclosed structure has a good grip, and the dripper can be more firmly inserted into the ground.

[0027] The joint 3 is a soft rubber joint 3 , which is convenient for it to be better connected to the step column 21 of the top cover 2 , and is also convenient for a water bottle to be put on the joint 3 .

[0028] The connector 3 can be connected to a variety of water bottles with different calibers, such as Figure 4 As shown, there are three steps 31, so three caliber water bottles can be connected. Mineral water bottles, Sprite bottles, etc. can be adapted for use, and these bottles are commonly used in daily life, and are also economical and practical, and can achieve waste utilization; of course, in actual use, the bottom of the water bottle should be opened to maintain the pressure inside and outside the bottle body to facilitate water discharge.

[0029] Of course, the above are only preferred embodiments of the present invention, and the patent scope of the present invention is not limited thereto. All simple modifications and equivalent structural changes made using the description and drawings of the present invention should be included in the patent protection scope of the present invention.
