The invention relates to agriculture, in particular, to devices for watering houseplants. A device for drip irrigation, containing tank, a dispenser, a discharge tube, pipe, and tank provided with an air tube and the outlet tube of the air layers, placed at the same level and facing the open part up to the dispenser, which is airtight (see USSR author's certificate N 1715257, A 01 G 27/00, publ. 29.02.92).

A disadvantage of the known device is the lack of fine adjustment of the rate of fluid outflow. In this device it is impossible to get small doses for irrigation, which limits its use for watering plants that require small and infrequent doses of liquid.

A device for watering indoor plants, containing an accumulation tank, the siphon tube, the fluid dispenser, made in the form of a conical vessel, a larger base of which is directed to the funnel, and the lower base to the inlet nozzle and the cavity of the dispenser and the storage tank communicated with each other through the siphon tube (see USSR author's certificate N 1701191, MKI A 01 G 27/00, publ. 30.12.91).

However, de nozzles of different length. The device is difficult to provide watering plants in small and infrequent doses.

Known installation for automatic watering of plants containing the reservoir of feed fluid with adjustable drip reservoir-dispenser, fixed under drip through horizontal axes of rotation, and the reservoir-dispenser system pipelines, and on the side walls of the reservoir-dispenser made of vertical guides, which are placed in the axis of rotation can be locked in different positions (see USSR author's certificate N 940708, A 01 G 27/00, publ. 07.07.82).

The disadvantage of this setup is the instability of the expiration of the drops from the dropper. When full, the reservoir supplying fluid pressure fluid to drip more, when the flow rate drops higher than for minor filling of the vessel. Speed adjustment the expiration of the drops is made by a valve (change of a lumen of the tubule dropper). In this device for receiving low doses of irrigation fluid must have a sufficiently small size canaliculi, which quickly becomes clogged with salt deposits from the liquid fuel. In this case, the device becomes izvestnyh technical solutions is their inability to apply for watering one plant, which requires rare and small doses of irrigation due to the high flow rate drops, leading to waterlogging of the soil.

The invention solves the problem of watering one or more potted plants predetermined doses of a wide range of intervals of time in the simplicity of manufacture and operation of the device. The most effective device when watering one plant, requiring small doses of irrigation.

The problem is solved in that the device for watering plants containing the reservoir of feed fluid to drip and drive dose with the discharge tube, is placed under the drip in the tank feeding the liquid set air chamber, the bottom of which, in particular, is part of the bottom of the tank, and the air chamber communicates with the reservoir of feed fluid through the holes located in the lower part of its side wall, and provided with a tube (to message her with the atmosphere), performed with the regulator entering atmospheric air, moreover, the air supply regulator to the air chamber made in the form of an air valve, consisting of a sealing gasket and screws placed in the part of the tube communicating with toroi removed from the tank and is a discharge tube, and its other end is located at the bottom of the tank, with the upper part of the siphon tube is spring-loaded ring that is installed with the possibility of reciprocating vertical movement to change the position of the specified part of the tube.

In Fig. 1 shows a General view of a device for watering indoor plants.

The device comprises a sealed tank 1 which is filled with irrigation fluid, in particular through the hole in it (figure not shown), which is then tightly closed. Inside the tank 1 is the air chamber 2. In their General day made (is) dropper 3 in the form of holes. In the side wall of the chamber 2 has an opening 4, which connects the volume of the chamber 2 with the tank 1. Inside the chamber 2 is an air tube 5 passing through the common wall of the chamber 2 and the tank 1. In part of the air tube 5, a member of the chamber 2 has an opening 6, and part of the tube 5 located outside the tank 1, there is an air valve 7 formed sealing gasket 8 and the clamping screw 9, which regulates the admission of atmospheric air through the opening 10. Below the hole 10 is located the sump 11 (for collecting accidentally caught in an air tube 5 of irrigation fluid and avoid clogging of the apertures 10). Under the dropper 3 posted by the drive 12, inside of which there are flexible siphon tube 13, the upper portion 14 which is spring-loaded ring 15 mounted with the possibility of reciprocating vertical is x2">

The device operates as follows. Irrigation liquid from the reservoir 1, the filling volume of the chamber 2 through the opening 4 to the upper part of this hole goes through the dropper 5 in drive 12 doses. Filling the drive 12 doses dot the upper part 14 of the siphon tube 13, the portion of the liquid flows on the water surface through the opening 16. Serving pour the irrigation fluid is defined by vertical moving ring 15 of the drive 12 doses. This ring 15, clenching and unclenching flexible siphon tube 13, changes the height position of the upper part 14. The flow rate drops from the tank 1 via IV 3 is set by adjustment of the air valve 7, by moving the clamping screw 9. The opening 10 is covered by a sealing gasket 8, reducing or increasing the amount of air supplied to the chamber 2. The number of incoming air into the chamber 2 through the opening 6 determines the flow rate drops.

The pressure of the liquid tank 1 to port dropper 3 is constrained by the forces of exhaustion. Until the liquid level in the chamber 2 will not decrease below the upper edge of the hole 4 and a part of air from the chamber 2 is transferred to the tank 1, the leakage of fluid from reservoirl pressure of the liquid column in the chamber 2. The lowering of the liquid level in the chamber 2 is compensated by the inflow of liquid from the tank 1 to the upper part of the hole 4.

The input end of the siphon tube 13 located at the bottom of the drive 12 doses, preferably with an expanding part with the inlet of the cone-shaped (as shown in Fig.) or in the form of a hemisphere or a nozzle in the form of a tube of larger diameter to provide an uninterrupted cycle (tube 13) work by eliminating entrainment of air drops of water doses of irrigation fluid at the moment of its completion. This embodiment of the end of the tube 13 is most useful when a small diameter tube 13.

In the proposed device, when performing the clamping screw 9 from a material with a small coefficient of linear expansion, for example, of steel, and the air valve from a material with a large coefficient of linear expansion (for example, polyethylene), depending on the ambient temperature, availability and whether the lack of sunlight pressure of the clamping screw 9 on the seal 8 will be adjusted automatically, and, therefore, will be automatically adjusted and the water supply (at elevated ambient temperature frequency of doses tion, convenient to use. Provides the choice of irrigation doses of fluids in a wide range, it is not affected by the presence of salts in the irrigation liquid (due to the possibility of using holes dropper larger than in known devices) under irrigation in small doses. Technologically, the device can be run from a removable drive dose that allows you to expand the technological capabilities of the device by using, where necessary, only the tank with liquid to a continuous drip irrigation. This technical solution prototype, the operation of which confirms the above-mentioned advantages of the proposed device. On this basis it is concluded that the technical solution meets the criterion of "industrial applicability".
