[0035] The following further describes the present utility model with specific embodiments in conjunction with the attached drawings:

[0036] See Figures 1 to 8As shown in the figure, a water-dripping device with adjustable water volume includes a water storage tank 1 and a water-dripping device 2. A fixed column 24 is arranged on the water-dripping device 2. The water-dripping device 2 includes a fixed seat 22 and a connecting seat 21 which are movably connected. A water-dripping hole 222 is arranged on the fixed seat 22, and a water outlet hole 212 communicating with the water storage tank 1 is arranged on the connecting seat 21. A connecting groove 221 is arranged on the fixed seat 22, and a connecting portion 211 is arranged on the connecting seat 21. A diversion groove 213 connecting the water outlet hole 212 and the water-dripping hole 222 is formed between the connecting portion 211 and the connecting groove 221. The cross-section of the diversion groove 213 gradually increases or decreases along the relative movement direction of the fixed seat 22 and the connecting seat 21. The water outlet hole 212, the diversion groove 213 and the water-dripping hole 222 are sequentially connected to form a water flow channel. By controlling the relative movement of the connecting seat 21 and the fixed seat 22, the water-dripping hole 222 or the water outlet hole 212 is connected to different positions of the diversion groove 213, so that the minimum cross-sectional area of the water flow channel changes, and further the water flow velocity in the water flow channel is controlled.

[0037] In the above structure, the cross-section of the diversion groove 213 gradually increases or decreases along the relative movement direction of the fixed seat 22 and the connecting seat 21. During use, by controlling the connection of the water-dripping hole 222 or the water outlet hole 212 to different positions of the diversion groove 213, the minimum cross-sectional area of the water flow channel changes, and further the water flow velocity in the water flow channel is controlled. The structure is simple and does not require additional parts for control, which is convenient for the assembly and production of the water-dripping device. Moreover, in this structure, the connecting seat 21 is not easily moved relative to the fixed seat 22 due to accidental touch, avoiding accidental changes in the flow rate of the water-dripping device and facilitating the use by the user.

The side wall of the connecting hole 11 is conical, and the diameter of the connecting hole 11 gradually increases from top to bottom. A first sealing wall 2161 adapted to the connecting hole 11 is provided on the outer periphery of the connecting protrusion 216. Under the action of gravity, the side wall of the connecting hole 11 abuts against the first sealing wall 2161 and seals the connection position between the connecting protrusion 216 and the connecting hole 11. During use, under the action of gravity, the side wall of the connecting hole 11 will abut against the first sealing wall 2161. This structure is beneficial to improving the sealing performance of the connection position between the connecting protrusion 216 and the connecting hole 11, avoiding water from flowing out of the gap between the water storage tank 1 and the connecting seat 21 during use, and facilitating the use by the user.

[0041] When the connecting portion 211 and the connecting groove 221 are slidably connected, the guiding groove 213 extends along the sliding direction of the connecting portion 211. The guiding groove 213 has side walls inclined with respect to the sliding direction of the connecting portion 211, or the guiding groove 213 has a plurality of side walls arranged in a stepped manner along the sliding direction of the connecting portion 211. The slidably connected connecting portion 211 and connecting groove 221 are both convenient for the control and adjustment of the drip irrigation device, facilitating the use by the user. The inclined side walls or stepped side walls have a simple structure, facilitating the production and processing of the guiding groove 213.

[0042] In the present utility model, it is preferably that the connecting portion 211 and the connecting groove 221 are rotatably connected. The guiding groove 213 extends along the rotating direction of the connecting portion 211. The guiding groove 213 has a spiral side wall, or the guiding groove 213 has a plurality of side walls arranged in a stepped manner along the rotating direction of the connecting portion 211.

[0043] An annular protrusion 214 is provided on the outer periphery of the connecting portion 211, and an annular clamping groove 223 is provided on the side wall of the connecting groove 221. The annular protrusion 214 is rotatably connected to the annular clamping groove 223 and can seal the connection position between the connecting portion 211 and the connecting groove 221.

[0046] During use, the floating member 4 blocks the water inlet hole 217 under the buoyancy of water. When the water in the transition cavity 25 flows out from the drip hole 222, the water level in the transition cavity 25 drops, so that the floating member 4 is separated from the water inlet hole 217, and the water in the water storage tank 1 can flow into the transition cavity 25 through the water inlet hole 217. This structure can reduce the influence of the water pressure in the water storage tank 1 on the flow rate of the water in the drip hole 222.
