Technical Field

The invention belongs to the technical field of machinery, and relates to a sprayer, in particular to a sprayer with multiple liquid supply modes.

Background

In agricultural production, a wide range of users operate the portable sprayer by a single person. The current agricultural sprayer mainly comprises a manual sprayer and an electric sprayer. Wherein, the manual sprayer drives the piston to realize high-pressure spraying by manually pushing the push rod. The electric sprayer is powered by a high-pressure water pump to realize spraying. Due to the application of the storage battery and the light water pump, the electric sprayer is widely applied to agricultural production, and the labor intensity of farmers is reduced to a great extent. The existing electric sprayer mostly adopts a diaphragm pump as a power element, and the diaphragm pump has the characteristics of high pressure and good reliability. However, the conventional electric sprayer is heavier than a manual sprayer due to the additional power supply and water pump, and requires a certain space for disposing the power supply and the water pump, resulting in a relatively smaller amount of water to be carried by the electric sprayer than the manual sprayer.

In order to solve the above problems, a new sprayer has been designed, for example, chinese patent application No. 200910189103.6 discloses a sprayer with a water absorption function, which comprises a water tank; the dispensing device is connected with the water tank; the water absorption and liquid spraying reversing device is arranged in the bottom box at the lower part of the water tank; the liquid spraying device is provided with a spray head capable of spraying liquid and absorbing water, the liquid spraying device is arranged outside the water tank and is connected with the water absorbing and liquid spraying reversing device, the spray head can spray liquid or absorb water through switching of the liquid spraying and water absorbing functions of the water absorbing and liquid spraying reversing device, and the pesticide stock solution can be quantitatively added into the water tank through the pesticide supplying and dispensing device. Although the problem that the existing electric sprayer carries a small amount of water is solved to a certain extent by the scheme, the electric sprayer has the following defects: because the water absorption and the liquid spraying are realized by the same nozzle, the liquid can not be sprayed simultaneously in the water absorption process once, and the spraying efficiency in the agricultural production process is seriously influenced. In addition, if the water absorption function is started, the electric energy of the storage battery is consumed, and if long-time spraying operation is needed, higher requirements are provided for the cruising ability of the storage battery, so that the cost is increased.
