The inventive utility model relates to stationary household filters in which water is purified when moving through the filtering medium from top to bottom by gravity under the influence of gravitational forces, in particular household filters for the purification of cold tap water, which purifies the water or passes it when switching to the corresponding mode.

Currently, there are a large number of stationary water filters designed for mounting on a faucet, differing in the original design and variety of materials from which the filter elements are made.

The prior art filter for water purification (certificate of the Russian Federation for utility model X214928 from 01/15/2000, C02F 1/18), containing a housing, a sorption porous filter element placed in it, an inlet pipe for introducing purified water into the spout filter and an outlet pipe to remove purified water. The filter element of the known filter is made of sintered ceramic material obtained by the method of self-propagating high-temperature synthesis in the form of a disk with a conical lateral surface with an angle of inclination of 10-30 °, installed in the filtration direction with a cone pointing down, sealed in the housing with a rubber conical gasket and fixed with a cover . The inlet pipe is equipped with a rubber sleeve and a union nut for connection to the water supply.

The known device is quite effective in purifying tap water, however; it does not provide the use, if necessary (for household needs) of water coming from the tap without additional treatment, since it does not contain a switch for the direction of water flow.

The prior art filter for the purification of drinking water according to the certificate of the Russian Federation for utility model No. 12366 of 08/26/1999, 7B01D 24/08. The known filter comprises a housing with a filter element and means for changing the direction of the flow of water, placed in a housing provided with a fastening element on the spout of water, a pipe

and switch. A removable adapter connects the filter housing

element and pipe body means changing the direction of flow of water.

In one embodiment, a means of changing the direction of the flow of water

installed at the entrance to the spout of water.

The disadvantages of the decision on the certificate of the Russian Federation on the utility model JVb 12366 can

the difficulty of replacing the filter element. When replacing the filter

element is necessary to disconnect the filter from the water tap and its disassembly.

In addition, the known device is not equipped with an aerator (means for saturation

water with oxygen), which improves the quality of ordinary water that has not passed filtration.

The last of the analogues, in our opinion, is the closest in

the technical nature of the claimed utility model and is selected as a prototype.

The objective of the utility model is to overcome these shortcomings and create

devices structurally uncomplicated, reliable and easy to use,

allowing quick replacement of the filter element without removing

filter from the tap and without disassembling it.

The technical result consists in increasing the reliability of the filter for

water and simplifying its use.

The technical result is achieved by the fact that in the water filter, including

a filter element housed in a housing with a nozzle and a removable cover,

means for changing the direction of the flow of water placed in a housing provided

a fastening element on a spout of water, a branch pipe and the switch, removable

adapter connecting the nozzle of the filter element housing and the nozzle

housing means for changing the direction of water flow,

a removable cover is installed in the bottom of the filter element housing and

additionally provided with at least one protrusion, the switch

made in the form of a three-way valve, and the adapter is additionally equipped with

at least one ledge.

For aeration of the water flow, a means of changing the direction of the water flow may be

additionally equipped with an aerator.

To ensure the transmission of a stream saturated with oxygen (in the mode of water discharge

washing without filtering) and effective filtering (in filtering mode)

the cross section of the inlet channel of the tap, and the side channel of the tap directing water to the adapter for subsequent filtration with a cross section of an area exceeding at least 50% of the cross section of the inlet channel of the three-way tap.

Installing a removable housing cover of the filter element in its bottom allows you to replace the filter material without removing the device from the tap. To facilitate removal, at least one protrusion is made on the lid. The number of protrusions depends on the size of the filter and, accordingly, the cover, as well as the material from which the filter element housing is made.

Three-way valve simplifies the regulation of the direction of flow of water, and the aerator allows you to get oxygen-saturated water. The protrusion on the removable adapter performs a function similar to the function of the protrusion on the removable cover of the filter element housing.

The claimed utility model is illustrated by the following graphic materials: FIG. 1 is a General view of the device in section
