HRP20000355A2 - Electro-compressor knapsack sprayer - Google Patents

Description

The field to which the invention relates

This invention relates to a backpack sprayer that has a built-in system for compressing air in the agent tank using a built-in battery electrocompressor.

Technical problem

This improved the classic (manual) knapsack sprayer, which solved the problem of constantly removing the ice and pumping the knapsack sprayer.

Also, in terms of protecting the human environment, there are no harmful effects for the environment when working with such a backpack sprayer compared to a backpack sprayer for internal combustion engines.

State of the art

Until now, classic knapsack sprayers (hand pump) and knapsack sprayers powered by an internal combustion engine are known.

Presentation of the essence of the invention

The main goal of the invention is the installation of a system for air compression in backpack sprayers - which will meet the highest environmental requirements, and in addition to achieving a continuous certain pressure in the body of the sprayer, noise reduction during engine operation, automatic regulation of air compression, very low weight of the sprayer.

Brief description of the drawing

The drawing shows the figure of an electric accumulator sprayer with all its elements:

1. Sprayer body

2. Electric battery compressor

3. Batteries

4. Distribution box-switch

5. Sprayer handle

6. Tank cover

7. Belt for carrying the tank

8. Pressure switch

Detailed description of the realization of the invention

The accompanying drawing, which is included in the description and forms an integral part of the description of the invention, illustrates the system and mode of operation of the electrocompressor sprayer:

1. Body of the sprayer (on which other parts of the electrocompressor, belt, battery, pressure switch, two outlets and one valve through which air enters to compress the sprayer are attached).

2. Electrocompressor (works on direct current that it receives from batteries located on the body of the sprayer).

3. Batteries (they are installed on the body of the sprayer and connected to the distribution box on which there is a switch and a socket through which the batteries can be charged without removing them from the body of the sprayer).

4. Electrical distribution box with a switch (on the electrical distribution box there is a switch for turning on the compressor which is still connected to the switch on the pressure switch that regulates the pressure in the sprayer by turning the compressor on and off; then the socket for charging the battery so that it does not have to be removed from the body of the sprayer during charging, and the socket with which the sprayer can be connected to single-phase current via an adapter, which is also used for connection to the car installation).

5. Sprayer handle (with valves and hose).

6. Sprayer body cover.

7. Belt for carrying the sprayer.

8. Pressure switch (which is located between the compressor and the body of the sprayer, is connected via the junction box to the circuit through which the electrocompressor is switched on, and has the function of controlling the air pressure in the body of the sprayer).

Method of application of the invention

This invention makes it easier to work with a backpack sprayer compared to the ones known so far. The characteristic of the electrocompressor backpack sprayer is that it is easily portable, that it does not create noise when working with it, and that it has a continuous certain pressure in the body of the sprayer, and in this way a greater effect is achieved in terms of the time it takes to spray a certain surface, as well as the the greater savings n funds.

The advantage of sprinklers is that there are no harmful effects on the environment when working with an electrocompressor.

Claims (5)

1. The knapsack sprayer, characterized by the fact that it consists of a sprayer body, batteries, a battery electrocompressor, a pressure switch and a distributor-switch, is designed so that with the help of a battery electrocompressor, the air in the sprayer body is compressed, which, due to the force of gravity, ejects the spraying agent at the opening that located at the bottom of the sprayer body. 2. The knapsack sprayer is characterized by the fact that a battery (accumulator) is located in the body of the sprayer, which serves as an energy source for the operation of the electrocompressor. 3. The knapsack sprayer is characterized by the fact that there is an electrocompressor on the body of the sprayer that compresses the air in the sprayer tank. 4. The knapsack sprayer is characterized by the fact that there is a pressure switch on the knapsack sprayer that controls the lowest and highest set values of compressed air in the sprayer body by turning on and off the electrocompressor. 5. The backpack sprayer is indicated by the fact that on the body of the sprayer there is an electrical distribution box that contains a circuit breaker between the batteries (2) and the electrocompressor (3), and between them there is also a pressure switch (4) connected to the circuit (+) that regulates compression of the air in the body of the backpack sprayer by the passing of direct electrical energy necessary for the operation of the electrocompressor.
