[02] The utility model relates to devices for cleaning liquids, in particular to devices for filtering tap water through the adsorption-bactericidal material of filter elements in domestic conditions and can be used to purify and improve the quality of drinking water by filtering.

[03] State of the art

[04] From the prior art, devices for purifying liquids, in particular water by multi-stage filtration, are widely known.

[05] Among the currently popular household water filters, one can point out devices of the Aquaphor trademark manufactured by Aquaphor LLC (https://www.aquaphor.ru), Geyser trademark manufactured by Aquatoria LLC (https: //shop.geizer.com), Aquabright trademark produced by Terra Water Group LLC (https://aquabright.ru/ru).

[06] The devices known to the Applicant have a similar design, which is characterized by the presence of a housing that has an inlet for supplying purified water and an outlet for purified water and filter element holders mounted on the housing, each of which has bayonet mounts for filter elements, while the holders filter elements are located in the lower working position without the possibility of rotation in a vertical plane, which makes it inconvenient for the user to install replaceable filter elements in a vertical position, as well as their replacement, the frequency of which can reach more than once every six months.

[07] The closest analogue (prototype) of the utility model is the attachment unit for filter elements for water purification, described in the Korean patent KR101281585B1, 04/04/2011. Said filter element attachment unit includes a housing that has an inlet for supplying purified water and an outlet for purified water and filter element holders mounted on the housing, each of which has bayonet mounts for filter elements, an outlet for supplying water to the filter element, an inlet for return water from the filter element into the body of the attachment unit, connected with the inlet and outlet, forming together with the filter elements a single channel for the passage of treated water. At the same time, the filter element holders are installed on the housing with the possibility of rotation in a vertical plane independent of other holders between the raised installation position and the lowered working position.

[08] The main disadvantage of the analog is the inconvenience of servicing the filter element attachment unit, which consists in the need to hold the filter elements with the user's hand during their installation. When replacing filter elements, it is not possible to fix the holder without an installed filter element in a position convenient for the user, as well as to smoothly move the installed filter element to the working lower position under its own weight without contact with the user's hand. If the user does not hold the filter element, the risk of damage to the filter element as a result of impact on the adjacent surface to which the filter element attachment unit is attached increases.

[013] In particular cases of implementation of the utility model:

[014] - the inlet for returning liquid from the filter element housing to the housing of the filter element attachment unit is made in the center of the filter element holder, and the outlet for supplying liquid to the filter element housing is made annular and placed concentrically around the inlet;

[015] - filter element holders are mounted on the housing of the filter element mounting unit with the possibility of the specified rotation in the vertical plane at an angle of not more than 90°;

[016] - means for fixing the filter element holder is made in the form of a microlift with a friction element;

[017] - means for fixing the holder includes a support and a friction element placed between said support and the hinged part of the holder;

[018] - the friction element of the means for fixing the filter element holder is made in the form of at least one elastic ring;

[019] - control marks are applied on the filter element holders;

[020] - the control mark of the holder is made in the form of a triangular pointer;

[021] - the housing of the filter element attachment unit has means of attachment to a vertical surface;

[022] - means of fastening to a vertical surface are made in the form of mounting holes.

[023] Unlike the closest analogue, the housing of the claimed filter element mounting block provides a fixation means that ensures that the empty filter element holder is held in a raised installation position at any angle convenient for the user, the value of which can reach up to 90 ° from the vertical surface to which the block is attached fastening of filter elements for liquid purification, as well as smooth lowering of the filter element holder to the lower working position under the weight of the installed filter element. This action of the fixation means is due to the effect of the holding force (in particular, due to the frictional force) on the hinged part of the holder.

[024] Thus, the design of the filter element attachment unit for liquid purification provides:

[025] - simplification of the installation and replacement of filter elements due to a more convenient location of the filter element and the absence of the need to hold the filter element by hand when lowering it;

[026] elimination of the impact of the filter element on the adjacent vertical surface due to the smooth lowering of the filter element holder under the weight of the installed filter element.

In the version of the block with three holders (4), it contains four fixing means (9), two of which are placed between the holders (4), the remaining two fixing means (9) are placed in the extreme left and extreme right positions, respectively. In this case, each means of fixation (9) includes a support (10) (body) and at least one friction element (11) placed between the support (10) and the hinged part (15) of the holder (4) with frictional effect on the specified hinged part (15). The friction element (11) is made, in particular, in the form of an elastic rubber ring. The number of friction elements (11) (rings), their size, material and gap between the hinged part (15) and the support (10) can be selected based on the weight of the filter element (12). Other embodiments of the fixation means (9) are also possible, for example, using a spring mechanism or a gas spring (gas lift).

[040] The housing (1) of the block may have means of fastening (14) to a vertical surface, such as a sink wall or a wall. Mounting means (14) can be made in the form of mounting holes.

[041] On the holder (4), as well as on the upper part of the filter element (12), control marks (13), (16) can be placed to control the correct installation of the filter element (12) when the mark (13) of the holder (4) is aligned with the mark ( 16) filter element (12). Control marks (13), (16) can be made, in particular, in the form of a triangular pointer.

[042] The filter element mounting unit for cleaning the liquid functions as follows. The body (1) of the unit is fixed to a vertical surface, for example, to the wall of a sink or a wall with self-tapping screws using the fastening means (14) provided on the body (1), and connected to a source of liquid (tap water) and to a tap of a purified liquid (pure water). ) by connecting plastic tubes to the inlet (2) and outlet (3) holes of the housing (1), respectively. The tubes are fixed in these holes (2), (3) by means of collet bushings installed in the holes (2), (3). When the liquid being cleaned is supplied to the developed device, the liquid sequentially passes from the inlet (2) opening of the housing to the outlet (6) to supply liquid to the filter element housing (12), then the liquid returns from the filter element housing (12) to the housing (1) of the filter element attachment unit through the inlet (7), then the liquid, according to the described scheme, alternately passes through all available filter elements (12), providing the necessary purification steps, so that ultimately the purified liquid through the outlet (3) enters the tap of the purified liquid (pure water ). To install the filter element (12), the empty holder (4) is lifted into the installation position at any convenient angle, the value of which can reach up to 90° from the vertical surface to which the housing (1) of the filter element attachment unit is attached. The holder (4) without the filter element (12) is held in this installation position by actuation of the locking device (9). Next, the filter element (12) is inserted into the bayonet mount (5) of the holder (4), rotated at an angle of up to 90° clockwise until a characteristic click and control marks (13), (16) in the form of triangular indicators in the upper part of the filter element (12) are aligned. ) and the holder (4), after which the holder (4) with the installed filter element (12) is smoothly lowered under its own weight into a vertical position under the influence of the friction element (11) of the fixation means (9) on the hinged part (15) of the holder (4).

[043] Thus, a technical result is achieved, which consists in simplifying the processes of installing and replacing the filter elements of the filter element attachment unit for cleaning the liquid due to the presence in the filter element attachment unit of the possibility of holding the holder without the filter element placed in it in a raised installation position and smoothly lowering the holder to the lower working position under the weight of the filter element installed in the holder, as well as the exclusion of the impact of the filter element on the adjacent vertical surface to which the filter element fastening unit is attached.
