Description

The utility model relates to sanitary equipment, namely to a device for raising and lowering a seat with a toilet lid in public and private toilets. The utility model is applicable to all models: toilet bowls and installations.

The closest analogue of the utility model, taken as a prototype, is a device for lifting a seat with a toilet lid. It consists of a hydraulic lift located under the seat with a toilet lid; a pipe for supplying and relieving water pressure with a hydraulic lift, and on the other hand, with a water supply tap, and made with the possibility of interacting with the water drain button located on the toilet bowl to ensure that the hydraulic lift is filled with water in order to increase it in size and ensure that the seat with the toilet cover is lifted , and on the pipe for supplying and relieving water pressure there is a safety valve necessary to limit the water pressure in the hydraulic lift, and a damper for draining water from the hydraulic lift into the drain tank (RU 206796 U1, 09/28/2021).

The disadvantage of this technical solution is the complexity of the installation, requiring the re-equipment of the drain valves of the toilet bowl.

The utility model is based on the technical problem of hygienic use when lifting and lowering a seat with a toilet lid in toilets.

The technical result of the claimed utility model is the simplification of installation.

The technical result is achieved by the fact that the device for lifting the seat with a toilet lid contains a lifting hydraulic cylinder attached under the toilet cistern at the place where the seat with the toilet lid is attached, consisting of a cylindrical housing in which a piston with a rubber cuff and a rod is located, and inlet and outlet fittings , a tee with a water flow regulator and a safety valve installed on the water supply pipe from the water supply line to the toilet flush tank, while the first outlet of the tee is made with the possibility of filling the tank, and the second outlet contains a built-in automatic valve connected to a hydraulic cylinder for lifting the lid and toilet seats, and a water pressure reducer installed in front of the tee on the water supply pipe from the water main to the toilet cistern to maintain a constant water pressure.

In addition, the hydraulic cylinder uses the pressure of the water in the water line as energy to lift the seat with the toilet lid.

In addition, additionally, the time of lifting the lid and the seat is less than or equal to the time of filling the toilet bowl.

The utility model is illustrated by drawings.

In FIG. 1 shows a general view of a device for lifting a seat with a toilet lid.

In FIG. 2 shows a tee with an automatic valve.

In FIG. 3 shows a hydraulic cylinder.

In FIG. 4 shows the arrangement of the lid and toilet seat.

Let's consider a utility model on the example of a toilet bowl and a tank with a bottom connection, the model is also applicable to a toilet bowl and a tank with an top connection.

The device for lifting a seat with a toilet lid, shown in Fig. 1 consists of three main parts connected to each other: a tee with an automatic valve (1), a hydraulic cylinder (2), a toilet seat with a lid (3).

Shown in FIG. 4, a seat with a toilet cover (3) consists of an arc-shaped bracket (15), a hydraulic cylinder rod (14), a seat mounting platform with a cover, and a hydraulic cylinder screw mounting with a seat mounting platform with a cover (3). When the lid and seat (3) are raised to the vertical position, the water from the line, which is the lifting substance, goes into the sewer from the outlet fitting (12) of the hydraulic cylinder (2).

Shown in FIG. 3 the lifting hydraulic cylinder (2) is attached under the toilet cistern at the seat attachment with the toilet lid (3). In this case, the hydraulic cylinder (2) consists of a cylindrical body, in which a piston with a weighting agent is located at the end of the rod (14), with a rubber collar, and inlet and outlet fittings (11, 12).

When exposed to the flow of water through the inlet fitting (11), the rod (14) of the hydraulic cylinder begins to descend. After the cover is fully raised, when the rod (14) of the hydraulic cylinder is in the lower position, the outlet fitting (12) opens, through which water flows into the sewer. When lowering the lid and the toilet seat (3), the rod (14) of the hydraulic cylinder rises, while the air is released through the air vent (13). The slow release of the lid is carried out by the stroke of the piston with a rubber cuff. To stop the water supply to the hydraulic cylinder from the water main, an automatic valve (9) located in the tee (1) is used. The diameter of the hydraulic cylinder is calculated based on the weight of the lid and toilet seat.

Shown in FIG. 2 tee (1) with an automatic valve (9) installed on the water supply pipe from the water main to the toilet flush tank (4). The first outlet (10) of the tee is designed to fill the tank, and the second outlet (6) contains a built-in automatic valve (9) connected to a hydraulic cylinder (2) to lift the lid and toilet seat (3). The tee (1) with the safety valve (9) is experimentally adjusted manually depending on the line pressure.

The water flow is divided into two streams. One outlet (10) goes to fill the tank, the second flow goes to the hydraulic cylinder to raise the seat with the cover. Under the influence of the adjusted water pressure in the line, the seat with the toilet lid (3) rises. After the water in the tank reaches the upper level, the flow of water into the tank stops at the outlet (10) and due to the increase in flow to the automatic valve (9) it closes by compressing the spring (8).

The device also has a water pressure reducer (7) installed in front of the tee (1) on the water supply pipe from the water main to the toilet flush tank (4) to ensure uninterrupted operation with unstable pressure in the line.

The principle of operation of lifting the lid and toilet seat (3).

The initial position of the seat with the lid (3) of the toilet bowl in the lower position. The reservoir valve is closed by water pressure in the tee.

When you press the button (5) to drain the water from the tank, water is supplied to the tee (1) with an automatic hydraulic valve (9).

After the water level in the tank (4) has risen, the pressure in the tee system (1) increases, as a result of which the automatic valve is activated, thereby blocking the flow of water to the hydraulic cylinder (2) and freeing the hydraulic cylinder cavity for a smooth reverse (up) piston stroke . The lowering of the seat with the toilet lid (3) occurs smoothly due to the resistance of the piston in the hydraulic cylinder (2).

When the piston of the hydraulic cylinder (2) is lowered, the rod (14) and the bracket (15) interact, thereby lifting the cover.

In this case, the lowering of the seat with the cover (3) occurs slowly and smoothly without slamming the toilet.

The claimed utility model can be installed on various models of toilet bowls already mounted and requires minimal installation complexity due to the fact that it is installed on the outside of the toilet bowl, and not inside, as in the prior art, patent number (RU 206796 U1, 09/28/2021). Thus, all the features presented in the formula of the utility model are essential and are in a causal relationship with the achieved technical result, which consists in simplifying the installation and hygienic use of the toilet.

In addition, the device for lifting the toilet seat with lid solves hygiene problems when using the toilet, since using the button is more hygienic than lifting the seat with lid (3) by hand, and since the button (5) is located higher, you do not need to bend down to lift the lid.
