Abstract

Usage: the invention relates to household appliances, in particular to siphons for preparing carbonated drinks and creams. SUMMARY OF THE INVENTION: the siphon head contains a non-return valve, which is made in the form of a channel connecting the nozzle channel to the internal cavity of the head, and an elastic collar with a flange mounted with a tension in the cylindrical groove of the internal cavity of the head and overlapping the channel exit surface. Gas from the canister passes through the channels, acts on the outer surface of the shell of the elastic sleeve, squeezes it and enters the siphon flask. After removing the canister from the needle and setting the pressure equal to atmospheric in the channels, the sleeve shell is additionally pressed by the pressure inside the flask and prevents the gas from escaping through the nozzle. The seal of the neck of the can is made in the form of a ring of round profile. 2 ill.

Description

The invention relates to devices using compressed air or gas acting directly or indirectly on drinks in tanks, in particular to the device for household siphons for preparing carbonated drinks and creams.

The purpose of the invention is to simplify, increase durability and reliability.

To do this, in the siphon head containing the housing, the release mechanism and the safety valve combined with it, a nozzle with a needle for piercing the diaphragm of the can, a neck seal of the can and a non-return valve, the latter is made in the form of a channel connecting the channel of the nozzle to the internal cavity of the head, in the latter an elastic collar with a flange is installed, overlapping the channel exit by the outer surface.

Comparative analysis with the prototype allows us to conclude that the siphon head is characterized in that the non-return valve is made in the form of a channel connecting the nozzle channel to the internal cavity of the head, and an elastic sleeve with a flange installed in the internal cavity of the head and overlapping the outer surface channel output.

Figure 1 presents the head of the siphon; figure 2 - cross section aa in fig. 1.

The siphon head contains a housing 1, in which an exhaust valve 2 is mounted, combined with a safety valve. A nozzle 3 with a center channel 4 is also mounted in the housing 1. A needle 5 is installed in the upper part of the channel 4 to pierce the diaphragm of the gas can. For sealing, a rubber o-ring 6 is installed in the upper part of the fitting 3.

ABOUT

the measure is in communication with the internal cavity 7 of the siphon head by channel 8. In the cylindrical recess of the internal cavity 7, a sleeve 9 of rubber with flanging 10 is installed with tension. The sleeve 9 externally closes the outlet of channel 8. When the head is screwed onto the siphon body (not shown) the flange 10 serves as a sealing gasket between the head and the housing.

To charge the siphon, the decorative cover 11 is opened and a cartridge holder (not shown) is screwed onto the nozzle 3, Needle 5 pierces the cartridge’s diaphragm, and gas, passing through channels 4 and 8, squeezes the sleeve 9 and enters the internal cavity of the head 7 and then into siphon flask. When the can is removed from the needle and the pressure in the channels 4 and 8 drops to the atmospheric sleeve 9, the gas pressure inside the flask is pressed against the walls of the inner surface of the head with even greater gain and provides reliable sealing of the siphon. With excessive pressure in the flask, the gas lifts the safety valve 2 and exits through the outlet channel 12.

For the carbonated beverage body, the handle 13 is pressed, the stem 14 is lifted and the valve 2 opens, releasing the beverage through channel 12.

The inventive siphon head is structurally simpler, in manufacture, repair and maintenance, less metal consuming. The design is simplified by the transfer of

a check valve from the fitting to the head cavity, eliminating from the fitting the valve stem with gas passage channels, which reduces manufacturing costs and simplifies assembly. The ring for sealing the can works on a smooth section of its neck, less force is required to seal this section, the ring deforms less and lasts longer. For flushing the non-return valve, disassembly of the nozzle is not required, access to the valve is open when filling the siphon with water. The exception of the threaded sleeve fitting and valve stem saves non-ferrous metal, which, for example, when releasing 100 thousand siphons per year will be at least 2.5 tons. SUMMARY OF THE INVENTION Siphon head comprising a housing, an exhaust mechanism and a safety valve combined with it, a nozzle with a needle and a seal that connects the can with gas and communicates with the channel with the inner cavity of the head, and a non-return valve, characterized in that, in order to increase reliability, the inner cavity of the head is made in the form ilindricheskogo recess for accommodating a non-return valve in form of an elastic sleeve flare mounted with interference and the possibility of overlapping its outer nozzle channel exit surface, wherein the seal fitting is configured as a ring of rubber round profile.  and g
