Description

The utility model relates to agriculture and can be used for chemical and biological protection of plants from pests and diseases, for sanitary treatment of rooms for animals and birds, for disinfection of rooms, and also for other purposes.

Known hand-held portable sprayers with an air pump (for example, a portable garden sprayer with an elliptical capacity, US 5072884, A 01 M 7/00; B 05 V 9/08, 12/17/1991) and sprayers with a hydraulic pump (for example, a backpack sprayer, EP 0410940, A 01 M 7/00; B 05 B 9/08, 01/30/1991).

Sprayer designs are also known, for example, RU 2256322, A 01 M 7/00, 07/20/2005; RU 2253230, A 01 M 7/00, 06/10/2005; RU 2253229, A 01 M 7/00, 10.06.2005, which have a complex structure, heavy weight, difficult to operate.

The closest is a hand-held portable sprayer, which contains a fluid container, a manual air pump, a fluid supply hose, a valve and a spray tube with the ability to move relative to the fluid reservoir, while the manual air pump is attached to the valve and the spray tube and connected to the reservoir for liquids with an air supply hose, a fluid supply hose is located inside the air supply hose (RU 2220785, 05 V 11/06, A 01 M 7/00, 01/10/2004).

A disadvantage of the known sprayer is the need to use a large operator effort to operate a hand-held air pump, which reduces processing productivity.

The utility model solves the problem of simplifying the design and increasing labor productivity and limiting the possibility of movement.

The problem is solved by the design, which is presented in FIG.

The sprayer contains: a container 1 with a working fluid 2, a submersible pump placed in a fluid 3, a solution level indicator 4, a spray nozzle 5, a nozzle mounted singly or multiple in a frame,

a control unit for fixed supply of working solution 6, a hose for supplying working fluid 7, a light source 8, an inverter 9, an electric power source 10, a counter for adjusting the supply of working solution - 11.

The sprayer works as follows.

The working fluid is poured into the tank, the power cable of the submersible pump is connected to the power source, the nozzle-sprayer is directed to the object being processed. Before the nozzle, a filter for cleaning the working fluid (not shown in Fig.) Is installed to prevent clogging. Through the inverter or directly from the power supply voltage is supplied to the pump. Processing is stopped either by turning off the power or by stopping the flow of the solution through the shut-off valve of the spray nozzle. When the minimum fluid level is reached, the pump shuts off automatically.

The proposed sprayer has several advantages compared with known devices.

Firstly, when working with a sprayer, the operator’s energy is not used, which leads to reduced fatigue and increased labor productivity. In this case, the operator’s attention is not distracted by bringing the sprayer into action, which increases the accuracy of spraying (it is important, for example, when painting).

Secondly, the possibility of using a battery current source for operation allows you to use the device autonomously, even in the field, and the ability to use a network current source ensures the efficiency of the device.

Thirdly, the ease of use of the sprayer (assembly, refueling, washing and changing filters), as well as the availability of all parts that can be bought at a hardware store, allows it to be used in small garden areas.

Fourth, a very important advantage is the absence of the need to seal the container with the working solution, as well as the completeness of the use of the working solution.

And, finally, the possibility of the most diverse application of the sprayer is the treatment of plants, soil, animals and birds, painting, applying fire-retardant coatings, etc.
