Description

The invention relates to liquid sprayers and sprayers and can be used to control pests and diseases of garden and vegetable crops.

Known liquid atomizer containing a spray head, a reservoir, a pump with a drive and a pipe with a check valve that informs the pump about the reservoir. The drive is made in the form of a spring-loaded pedal. To improve service conditions, the liquid atomizer is equipped with a second pump with an actuator in the form of a spring-loaded pedal. Moreover, the pedals are mounted on a stand with the ability to alternately press the feet of a serving person. The pipeline is mounted on a stand and is equipped with a handle located above the tank (see.with. N1711984 from 01/15/90, class B 05 V 9/043).

The disadvantage of this sprayer is its bulkiness and the ability to use it only in a stationary position, since the spraying process is combined with the operation of the foot drive of the pump. The spraying process is laborious.

Also known is an electric universal sprayer according to as N1729611 from 04/05/90, cl. 05 V 9/043. The sprayer contains an electromagnetic supercharger made in the form of a housing with a handle and a switch and an electromagnet installed in it with an armature, diaphragm and piston. In addition, the sprayer contains a suction hose with a filter, a pressure hose with a fluid flow regulator and exhaust nozzles. The fluid flow regulator is equipped with a check valve. The nozzles are mounted rotatably. The electromagnetic supercharger is equipped with an additional local switch connected by an extension cord to an electrical outlet.

The main disadvantage of this sprayer is insufficient safety during its operation. This is due to the fact that during operation the electric supercharger has direct contact with the employee (located in his hands), which creates an increased risk of electric shock and therefore requires a high degree of protection for the electric sprayer, which is associated with additional costs. In addition, it can be used only if there is an electrical outlet on the treated area, while the processing area is limited by the length of the extension cord connected to the outlet. The limited mobility of the sprayer is also associated with the need to use a separate container for the working fluid.

Closest to the claimed device is a sprayer OES-2, manufactured by Kiev OJSC Elektropribor (see Internet site http: //www.electropryеad.ukrbiz.net/prоd) .03htm. The sprayer contains an electric pump, intake and pressure hoses, a holder with a nozzle, and an electric cable.

The working fluid from a separate container through the intake hose is fed into an electric pump, which delivers it under pressure to the pressure hose, then into the holder and is sprayed with a nozzle mounted on the holder. The electric pump is powered through a cable from a 220 V 50 Hz network.

The disadvantages of the OES-2 sprayer are limited mobility, inconvenience in operation and insufficient safety when working with pesticides. The presence of a separate container for the working fluid, the need for a large length of the supply cable and pressure hose create a lot of inconvenience and limit the ability to move around the treated area. The presence of a 220 V 50 Hz network makes it necessary for the sprayer to have a high degree of protection against electric shock. The use of a short holder (not more than 1.5 m) limits the ability to process tall trees, and also does not provide a safe distance for the worker from the sprayed stream of toxic chemicals.

The aim of the invention is to increase ease of use, improving safety during operation, ensuring mobility and compactness of the device.

This goal is achieved in that the electric sprayer, which includes a container for working fluid, an electric pump, a holder, a spray, a hose, is additionally equipped with an autonomous power source for the electric pump, such as a battery, and the capacity for the working fluid is made sectional, in one of the sections of which the electric pump is located, and the other is an autonomous power source connected to a power button located on the holder, the holder being made telescopic and equipped with a hose winder, one end to torogo connected to the electric pump, and at the other end thereof mounted sprayer. At the same time, sections of the container for the working fluid can be made both internal and external, and the device for winding the hose can be manual or automated.

The supply of an electric sprayer with an autonomous power source, for example, a battery, eliminates the need for an electrical outlet in the treated area, which greatly expands the possibilities of using the sprayer and at the same time makes it safe against electric shock without the use of any protective equipment.

The implementation of the capacity for the working fluid sectional with the placement in the sections of the electric pump and an autonomous power source allows you to combine the components of the electric sprayer (tank, electric pump, power source) in a single compact design, which ensures the mobility of the device and significantly increases the convenience when moving around the treated area.

The implementation of the sections internal or external allows you to use containers for working fluid of various configurations.

Placing the power button on the holder makes it easy to use the sprayer.

The implementation of the telescopic holder allows you to increase the spraying height and at the same time increases the distance to the sprayed pesticides, which allows you to protect the work of the worker performing the chemical treatment. In this multi-section telescopic holder acts as a rod (the working fluid is supplied through a hose), and therefore does not require pressurized connections between sections, which allows you to increase the number of sections to the required length of the holder.

Providing the holder with a manual or automated device for winding the hose allows you to conveniently place the hose on the holder and ensures its compactness.

The installation of the spray gun on the hose eliminates leakage of the working fluid without the use of various hermetic seals, which increases the reliability of the sprayer.

Figure 1 shows a General view of the electric sprayer, figure 2 - embodiment of the container with sections made inside the container, figure 3 - section of the container is made external, figure 4 - telescopic holder in working condition with a manual device for winding the hose , Fig.5 is an embodiment of a telescopic holder with an automated device for winding a hose.

The electric sprayer contains a container 1 for the working fluid, an electric pump 2 and an autonomous power source, for example, a battery 3. The electric pump 2 is installed in section 4, and the power source 3 is in section 5 of capacity 1. Moreover, sections 4 and 5 of capacity 1 can be performed as internal both external. The electric cable 6 of the power source 3 is connected to the electric pump 2 and the power button 7 located on the holder 8. The holder 8 is made telescopic and provided with a device 9 for winding the hose 10, and one end of the hose 10 is connected to the electric pump 2, and is installed on the other end of the hose 10 atomizer 11. The container 1 is provided with a cover 12 and a shoulder or shoulder strap 13. Alternatively, the holder 8 may be equipped with an automated device 14 for winding the hose 10.

The electric sprayer operates as follows.

The tank 1 is filled with a working fluid and is closed by a cover 12. When the button 7, located on the holder 8, is turned on, the electric pump 2 is turned on, connected via a cable 6 to an autonomous power supply 3. The fluid flows from the tank 1 through a hose 10 to the atomizer 11. Direction a sprayed jet of working fluid is carried out using a telescopic holder 8, which allows you to adjust the spray height. The electric pump 2 and the power source 3 are located in sections 4 and 5 of the tank 1 and represent a single portable design. The electric sprayer is transported to the treated area using a shoulder or shoulder strap 13. After the work is completed, the telescopic holder 8 is folded, and the hose 10 is wound onto the device 13 manually or automatically using the device 14.

The proposed electric sprayer allows you to increase safety during operation, increases ease of use, provides mobility and compactness of the device.
