Description

Rechargeable electric watering can

Technical Field

The utility model relates to the technical field of watering cans, in particular to a rechargeable electric watering can.

Background

The watering can is a device which pumps water through a water pumping pipe and then discharges water from a spray head to spray water in a refined mode, and is generally suitable for garden technology, agricultural production, cleaning and disinfection and air humidification. The principle is that the water is sprayed from the spray head by the high pressure in the kettle by utilizing the pressure difference generated by the height difference of the water level. The traditional watering can is pressurized manually to generate pressure difference in the can, so that the process is complicated, and in the using process, the pressure of the watering can is always needed to be interfered by manpower.

Aiming at the problems, an electric watering can driven by a water pump is arranged, the electric watering can is powered by a battery, a strong pressure difference is generated through high-speed operation of the water pump, water is sucked from a water suction pipe and then sprayed from a spray head, and therefore high-speed water flow is formed, and water spraying operation is completed. One of the working principles is that the Bernoulli principle is applied, in a certain fluid, the flow speed is larger, the pressure is smaller, the flow speed is smaller, the pressure is larger, and the fluid flows from a high pressure place to a low pressure place.

The current electric watering can mostly adopts rechargeable battery as the power supply, when the electric quantity in rechargeable battery is exhausted, need take out the battery and charge it, install back in the electric watering can after charging is accomplished, this mode is complex in operation not only, if still can carry out the operation when the electric quantity is exhausted in addition, then need prepare two batteries and reserve, in actual operation in-process simultaneously, often because the staff's hand is stained with the in-pot liquid, battery electric quantity is exhausted, the staff is when tearing down the battery, liquid on hand can cause certain harm to the battery, thereby reduce life. In this respect, the improvement point of the prior art is to add a solar panel, but this cannot solve the problem that the battery needs to be detached and replaced. In addition, the existing electric watering can adopts the water pump to absorb water and spray water, however, when the power supply is turned off, the water pump stops running, the liquid in the water spray pipe still can go out water for a period of time through the water outlet holes, and the liquid can not be sprayed in a mist form but can flow out in a water flow form due to insufficient pressure.
