Detailed ways

The following describes a number of preferred embodiments of the present invention with reference to the accompanying drawings to make the technical content clearer and easier to understand. The utility model can be embodied through many different forms of embodiments, and the protection scope of the utility model is not limited to the embodiments mentioned in the text.

A preferred embodiment of a solar watering can according to the present utility model is shown in FIGS. 1-2 , which includes a water storage tank 1 and a watering can body 2 . The watering can body 2 and the water storage tank 1 are assembled through threads. The watering can body 2 includes a handle 3, a nozzle 10, a miniature water pump 7, a solenoid valve 8, a switch button 5, a solar charging board 9, and a lithium battery 4 arranged in the handle 3 and a switch button 5 arranged on the handle 3. When the switch button 5 is pressed, the elastic contact 51 connects the lithium battery 4 with the water pump 7 and the solenoid valve 8, and the water pump 7 pumps the water in the water storage tank 1 through the water inlet hose 11, and then through the water outlet hose 91 through the The solenoid valve 8 is ejected from the nozzle 10 through the nozzle inlet hose 101 .

After the user releases the switch button 5, the lithium battery 4, the water pump 7 and the electromagnetic valve 8 are disconnected, and the watering can stops spraying water. Under the action of the switch of the solenoid valve 8, when the power is cut off, the watering can can immediately close the water flow to prevent the spout from dripping.

When not using the watering can, the lithium battery 4 can be charged by the solar charging board 9. Under the irradiation of sunlight, lithium battery can be charged automatically, and anti-backflow device is housed on the solar charging board 9, when not working, energy storage is used for next time.

The watering can body 2 is provided with a charging port 6, and the watering can can also be charged through the charging port 6.

As shown in Figures 3-4, in a further embodiment according to this embodiment, a one-way valve 13 is arranged at the bottom of the water storage tank 1, and the one-way valve 13 is connected with a water-drawing pipe 15, and a pipe is provided on the water-drawing pipe 15. The joint 14, the siphon balloon 17 and the sink head 18 for drawing water are provided with a filter screen 19.

Since the volume of the water storage tank 1 is limited, increasing the water storage tank 1 will increase the weight of the watering can. Therefore for the spraying of the garden of larger area, need repeatedly add water for water storage tank 1 back and forth. And in this further embodiment, only need be that watering can 1 is connected at joint 14 and draw water pipe 15, and draw water sinker 18 and be placed in the external water source 16 such as the pool of garden, fish pond, lotus pond or water tank, waterway, brook. , then extrude the siphon balloon 17 so that the external water source 16 is communicated with the water storage tank 1, then close the atmospheric communication port of the watering can, start the water pump 7 to spray, then the watering can will be sprayed at this time, and the water level in the water storage tank 1 will drop. When the air pressure drops, the water in the external water source 16 is continuously replenished into the water storage tank 1 through the one-way valve 13 under the action of atmospheric pressure, so it can be continuously sprayed in large quantities to meet the requirements of large-area garden spraying. At this time, even if the switch button is released and the spraying is temporarily stopped, as long as the atmospheric communication port of the watering can remains closed, the water in the water pipe 15 will not flow back due to the atmospheric pressure difference between the water storage tank 1 and the outside world. Switch button 5, just can continue spraying. After spraying, remove the water-drawing pipe 15 from the pipe joint 14, the residual water in the water-drawing pipe 15 will automatically flow back to the lower external water source, and because the valve 13 is a one-way valve, the water in the water storage tank 1 Will not flow out. The filter screen 19 can filter the impurities in the external water source 16, so as to prevent the impurities from being sucked into the watering can and blocking the pipeline.

The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those skilled in the art can make many modifications and changes according to the concept of the present utility model without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the scope of protection defined by the claims .
