Abstract

FIELD: purification of drinking water.

SUBSTANCE: the invention presents a filter-nozzle for water purification and it is dealt with purification of drinking water, in particular, with means of filtration of water through adsorptive-bactericidal material in household conditions of life and may be used for purification and improvement of quality of potable water. The filter-nozzle contains a body made in the form of a cylinder with a lid, a filtrating module, a unit of connection to a source of water, a switch of water current, a unit of release of untreated water, a unit of withdrawal of purified water, a date designator. The filtrating module contains an inlet linked with a cavity of the cylinder of the body, a replaceable filtering member and an outlet linked with a unit of the purified water withdrawal. The unit of connection to a source of water consists of: a base, an adapter, a nut, a bush, a screw. The unit of release of unpurified water consists of: a base with installed in it a washer with holes, a nut with holes, a nut with holes a grid installed in it. The switch is made in the form of a valve with a lever. The valve has a ring-type groove used for a leakage of unpurified water and a longitudinal channel for water running into the filtrating module. The date designator is made as a band with inscribed on it names of months fixed in the lid holes. The unit of the purified water withdrawal is made in the form of a grove and a hole in the lid of the body. The technical result is an increase of productivity of the filter and improvement of conditions of the filter operation.

EFFECT: the invention allows to increase productivity of the filter and to improve of conditions of the filter operation.

Description

The invention relates to the purification of drinking water, in particular to means for filtering water through an adsorption-bactericidal material in domestic conditions, and can be used to purify and improve the quality of drinking water.

Known filter nozzle for water purification (certificate No. 12366, class B 01 D 24/08, publ. 09/10/99), comprising a housing with a filter module connected to a purified water outlet and a water flow switch connected to source of purified water and a channel for the release of untreated water.

The known filter does not provide the ability to connect to a water source of various designs, the ability to use a replaceable filter element, the ability to specify the filter resource, the ability to lighten the weight of the structure, the ability to improve water flow parameters.

An object of the present invention is to correct these drawbacks.

The technical result is to increase the efficiency of use of the filter and increase the usability of the filter.

The result is achieved in that in the filter nozzle for filtering water, comprising a housing with a filter module connected to a purified water outlet and a water flow switch connected to a purified water source and a raw water outlet, a connection block with a purified water source is introduced, connected to a water flow switch connected to the filtering module of the housing by a channel for supplying purified water to the filter, the housing is made in the form of a glass and a cover, the filtering module is installed in the glass of the housing and is made with By changing the filter element, the input of the filter module is hermetically connected to the housing cavity connected to the channel for supplying purified water, the output of the filter module through the channel of the housing cover is connected to the outlet for purified water, the housing cover is configured to install a data indicator, the connection block to the source of purified water is made with the ability to connect to a tap with an external or internal thread or to a tap without a thread, the water flow switch is made in the form of a spool that passes water into the feed channel chischaemoy water in the filter or in the raw water discharge unit block release of raw water is arranged to flow rassekaniya water.

The block diagram of the filter nozzle is shown in figures 1-6, where the housing 1, made in the form of a cup 2 and a cover 3, a filter module 4, a unit 5 for connecting to a water source, a switch 6 for water flow, a node 7 for the release of untreated water, the purified water output unit 8, the data indicator 9, the filter module 4 comprises an input 10 connected to the cavity 11 of the cup 2 of the housing, a replaceable filter element 12 and an output 13 connected to the purified water output unit 8, the connection unit 5 to the water source is made in the form of a base 14, adapter 15, nuts 16, bushings 17, screws 18, assembly 7 in The raw water discharge is made in the form of a base 19 with a washer 20 installed in it with holes, a nut 21 with aeration holes 22 and a mesh 23 installed in it, switch 6 is made in the form of a spool 24 with a lever 25, an annular channel 26 for flowing is made in the spool untreated water from block 5 to node 7 and a longitudinal channel 27 for water to flow into the filter module 4, the data indicator 9 is made in the form of a tape 28 with the names of months applied on it, fixed in the lid opening, the purified water outlet 8 is made in the form of a channel 29 andholes 30 in the cover 3 of the housing 1.

The filter nozzle operates as follows.

Untreated water from the tap enters the opening of block 5. If the tap is supplied without thread, the adapter 15 is attached to the tap by fastening (“tearing”) inside the tap of the sleeve 17 by compressing it with a screw 18 (hollow inside) connected to the adapter 15 carving. The adapter 15 is attached to the base 14 with a nut 16. If the water supply tap is made with an external thread, the adapter 15 is screwed onto the tap and fastened to the base 14 with a nut 16. If the water supply tap is made with an internal thread, the adapter 15 is screwed into the tap and attached to the base 14 with the nut 16. In the “without cleaning” mode, water (including hot) passes through the block 5 and the annular channel 26 of the switch 6 enters the node 7, where it passes through the holes of the washer 20 of the base 19 and the mesh 23 and leaves smooth aerated with holes 22 of the nut 21 stream.

Only cold water is cleaned at the optimum flow rate for this filter. To purify the water, the lever 25 of the switch 6 is rotated to a horizontal position (transverse to the flow). In this case, water flows along the longitudinal channel 27 of the spool 24 and through the cup 2 of the housing 1 enters the filter module 4, passes the cleaning layers in the replaceable filter element 12 and exits through the outlet 13 of the module 4 into the channel 29 of the node 8 and from there through the hole 30 to the consumer.

The filter effectively purifies cold tap water from impurities of active chlorine, phenol, organochlorine compounds, toxic and heavy metals, as well as other, including mechanical, impurities, and gives water bactericidal properties.

Activated silver-containing carbon and ion-exchange fiber materials are used as filter materials in an optimum ratio for this class of water purifiers.

To indicate the service life of the filter element, a rotating data indicator is used in the filter 9. By turning the tape 28 of the data indicator 9 in the cover window 3, the month of replacement of the replaceable filter element 12 is set.

Thus, the invention improves the efficiency of the filter and the usability of the filter.
