Description

DETAILED DESCRIPTION OF THE INVENTION The present invention uses a pressure gas cylinder as a source of carbon dioxide, which cylinder is removably mounted within the apparatus and which selects the gas in the bolt into the water to be carbonated. The present invention relates to a portable carbonated water production device of the type that includes a manual member for opening the device.

The gas cylinders used in such devices are fitted with valves and are therefore relatively expensive. The carbonated water production device of the present invention includes a valve adapter assembly, this assembly includes a rotating main body, the rotating main body has a valve chamber, a valve set is housed in the valve chamber, and the rotating main body has a valve chamber. A valve set is normally closed at one end of the chamber to isolate the inlet from the outlet, and the device has an actuating plunger, the actuating plunger being configured to facilitate selective opening of the valve set. Actuated on a valve set, the body comprises an internally threaded receiver, bid, for receiving a threaded neck of a pressure gas cylinder, and the inlet has an axially extending projection in the receiving hole. formed by a through pin, said through pin having an axial passage communicating said receiving hole with a valve chamber, said receiving hole having a gas cylinder engaged in said receiving hole at an inner end thereof; a sealing washer for engaging the neck of the receiving hole, and a small communication hole communicating a location within the receiving hole with the atmosphere.

This arrangement allows a cylinder with a relatively expensive valve to be replaced by a relatively cheap gas cylinder, which does not need to be sealed off by a breakable diaphragm. It has a threaded neck of the same type as before, with the exception that the small passage hole alerts the user when he attempts to remove a partially gas-filled cylinder. emanate.

When the sealing contact between the gas cylinder and the sealing washer is broken, the pressure gas escapes, and the outlet of the flow hole makes an audible sound, which prompts the user to re-tighten the cylinder into the receiving hole. This will give you a warning.

Preferably, the upper part of the valve body is fixed in a frame member of the device, and this fixation is reinforced by a rigid bracket fixed on one side to the frame member and on the other hand to the body of the valve. An embodiment of the present invention will be described below with reference to the drawings. The device of the present invention shown in FIG. 1 includes a casing 1 in which a sealing plug 2 and a gas radiation lance 3 are housed, and the lance. 3 cooperates with a bolt 4 temporarily installed in the device and also with a pivoting lever 5 and a cooperating sealing plunger 6 connected to the mounting block 7;
The mounting block 7 is provided with an outlet channel 8 and a threaded hole extending into the lance 3! Moreover, a valve adapter assembly 10 and a sealing washer 9 are housed in this hole.

The assembly 10 supports a replaceable carbon dioxide cylinder 11 having a threaded neck and sealed by a 4 breakable diaphragm prior to use of the device. The assembly 10
The structure of is shown in detail in FIG.

The assembly comprises a body 12 having an axial valve chamber 13 which accommodates a valve set, which valve set is connected to the annular seat member 1.
4, and this sheet member 14 is fixed in a sealing manner in the receiving hole at the upper end of the chamber. The valve set includes a valve member 16 having an annular sealing member 17 which is normally held to the seat member by a valve spring 18. A plunger 19 connected to the valve member projects upwardly through the seat member, thereby facilitating opening of the valve set. During use of the device, the plunger 19 is engageable with the sealing plunger 6 as shown in FIG.・
When the valve is open, an annular passage formed between the plunger 19 and the seat member 14 forms an outlet from the chamber 13. An inwardly threaded receiving hole 20 is formed at the lower end of the main body, and a piercing pin 21 extending in the axial direction is provided at the inner/side end (or upper end) of this receiving hole 20. pin 2
1 has a shaft passing through a passage 22 which connects the receiving hole to one end of the valve chamber 13 and forms an inlet for gas into the chamber. A sealing washer 23 is provided around the piercing pin,
The main body has a communication hole 24 extending in the direction of the half mold below the washer. As a normal safety precaution, the valve chamber 13 has a side boat 27 which is sealed by a rupture disc 28 which ruptures when excessive pressure is applied from within the valve chamber. It's becoming like that. Said mounting block 7 forming a fixed frame member has a transverse flange 30 to which said body 1 is attached.
The attachment of 2 is reinforced by a bracket 31 forming an inverted L-shaped part, a vertical top 32 screwed to said body at position 33 and two spaced apart horizontal webs secured to the flange 30 at position 35. ing. The bracket mounts the valve body 12 to the block 7.
This strengthens the threaded connection between the blocks which is subject to lateral forces inadvertently applied by the user to the body of the valve and the gas cylinder. During use, the gas cylinder 11 is screwed into the receiving hole 20, and at the final stage of insertion of the gas cylinder 11 into the receiving hole 20, the gas cylinder 11 is fitted with the washer 23.
The gas cylinder 11 is engaged in a sealing state with the gas cylinder 11.
has a diaphragm pierced by a pin 21;
For this reason, the chamber 13 is exposed to the pressure of carbon dioxide gas through the filter 26 located upstream of the inlet flow path 22 within the cylinder.

Excess pressure is released through the flow hole 24 when the cylinder is removed and any residual pressure is normally exhausted through the hole 24 by the time the cylinder neck is completely removed from the receiving hole. The jet of pressurized gas provides an audible warning, which informs the user that he is discarding a cylinder with residual gas and reminds him to re-tighten the cylinder into the receiving hole 20. will arise.
