The proposed invention relates to the field of drinking water supply, specifically to devices for electrochemical purification of drinking water, and can be used for purification of tap water in field and domestic conditions, as well as for purification of natural waters and bringing the physicochemical and organoleptic properties to meet the requirements for drinking water.

Electrochemical methods make it possible to most effectively purify water from anthropogenic impurities (Miklashevsky N.V. et al., Pure water. Purification systems and household filters. St. Petersburg: VHV-Saint Petersburg, publishing house "Arlit", 2000, p. 154) ...

A device is known that implements the method of electrochemical purification of drinking water according to patent RU 2043308, containing a container in which a package of electrodes with a soluble anode is placed, as well as a container with a filter element. The device also contains a power and control source with a step-down transformer and a rectifier connected to the AC mains and to the electrodes of the device.

There is also known a device for the electrochemical purification of drinking water (utility model) according to patent No. 36824, containing a power source, a reactor container with a package of soluble electrodes located in it and a filter container with a filter element, in the upper part of the reactor container is installed with the possibility of vertical movement, a buoyant open from above there is an easily removable reverse cone with a vertical handle, the filter tank is equipped with an easily removable fine filtering element, and a funnel with a ring magnet attached to the drain pipe is installed above the reactor tank.

The disadvantage of this device is that when creating a device for electrochemical purification of drinking water of small volumes for individual use, it is difficult to implement a set of design solutions used to miniaturize devices.

The known design of the device according to the patent RU No. 175909, which allows the manufacture of a device for electrochemical cleaning of small volumes for an individual user.

In this device, the inner surface of the reactor vessel in its open part is made partially conical so that the diameter of the lower base of this cone is less than the diameter of the base of an easily removable in the vertical direction of the reverse cone, made in the form of a float, equipped at the base with a seating band, mating with the inner conical surface of the container of the reactor, and having grooves for the contacts of the electrodes, the electrode package is formed by side removable strips with grooves for the electrodes, while the electrodes are located perpendicular to the bottom without touching it, and their contacts inside the upper part of the reactor vessel are simultaneously guides for the grooves of the easily removed reverse cone, ensuring its stable movement inside the reactor in the vertical direction, the funnel cover with a ring magnet is equipped with removable coarse and fine filters, the power supply cables are equipped with removable terminals for fastening to the electrodes contacts, while the terminals are equipped with fi by xators for deepening and holding at a predetermined depth of a buoyant reverse cone that is easily retrieved in the vertical direction after filling the reactor vessel with water. For transportation purposes, the individual parts that make up the device are housed in soft covers.

This device is taken as a prototype.

The disadvantage of the prototype is the lack of a single assembly structure for the device for electrochemical cleaning of small volumes for an individual user in field conditions, which is due to the implementation of the prototype in the form of separate blocks that must be assembled into a single device with each use. In addition, the implementation of the connection of the package of soluble electrodes to the power source through the slots in the reverse cone is unreliable and inconvenient in handling the device, leading to the need to maintain the balance of the reverse cone using an additional pair of contacts. This does not allow providing a device for electrochemical purification of small volumes for an individual user in addition to the properties of hermetic storage of water in field conditions and thus expanding functional devices.

The problem to be solved by the claimed technical solution is to expand the functionality of the prototype device.

The solution to this technical problem is achieved by the fact that in the known device for electrochemical water purification containing a power source, a reactor vessel with a package of soluble electrodes located in it, a filter vessel made in the form of a funnel, inside which removable coarse and fine filters are located, on a drain pipe of which an annular magnet is installed, while the surface of the reactor vessel is made partially conical in its open part, an easily removable reverse cone open from above is installed with the ability to move, and the electrode package is formed by side removable strips with grooves for electrodes, while the electrodes are located perpendicular to the bottom of the reactor vessel , the inverse cone is made in the form of a float, mating with the conical part of the surface of the reactor vessel, and the funnel of the filter vessel is made with the ability to remove it from the reactor vessel, in addition, the reactor vessel is equipped with a sealing cover-glass connected to p the surface of the reactor vessel using a hermetically sealed threaded connection, and the power source is located in a compartment connected along the perimeter with the surface of the reactor, while the power source is installed on a removable cover, using screws and stands fixed on the bottom of the reactor vessel from the compartment side, and the electrodes of the package soluble electrodes are made with the possibility of detachable hermetic connection through the bottom of the reactor vessel with the poles of the power source, while the device contains a unit for fine purification of electrolytically treated water, the inlet of which is connected to the reactor vessel through a pipeline, and the outlet with the discharge of purified water.

Supplementing the reactor vessel with a sealing glass lid connected to the surface of the reactor vessel using a sealed, threaded, detachable connection and making the electrodes of the package of soluble electrodes with the possibility of a detachable hermetic connection through the bottom of the reactor vessel with the poles of the power source (for example, in the form of poles, into which the pins of the electrodes are inserted) and a unit for fine purification of electrolytically treated water, the inlet of which is connected to the reactor tank through a pipeline, and the outlet with the discharge of purified water, makes it possible to expand the functionality of the prototype device and create a device convenient for use in field conditions.
