Description

[Detailed description of the invention] 1. Purpose of the invention The present invention relates to a carbonated water maker, which is a device for making carbonated water by injecting carbon dioxide gas into fresh water.

Conventionally, foreign-made and well-known devices of this kind have the disadvantage of being difficult to handle, and also have the disadvantage that it is not possible to clean the pot by inserting one's hand inside the pot. Therefore, the object of the present invention is to provide a new and practical carbonated water maker that eliminates these drawbacks of conventional devices.

2 Structure and operation of the invention The structure and operation of the invention will be explained with reference to the embodiments shown in the drawings.

Reference numeral 1 denotes a container body having a cylindrical shape as a whole, and a mouth portion 2 of this container has a wide diameter. 3 is a rubber base provided at the bottom of the vessel 1; 4 is a lid that is screwed onto the mouth 2 to seal it; a knob 6 with a safety valve 5 is provided in the center of the lid; There is. Reference numeral 7 denotes a connector having a through hole 8 installed in an opening provided in the upper side of the container 1, and a tube 9 extending to near the bottom surface is connected to the inner protrusion of this connector. Reference numeral 10 denotes a holder connected to the outer protrusion of the connector 7, and a space 11 formed inside the holder is provided with an extension bullet 12 and a cylinder 13 that abuts the rear end of the bullet.
The rod 14 of this cylinder 13 passes through the opening 15 of the holder 10 and has its rear end slightly projecting outward from the holder. The rod 14 is provided with a vertical hole 16. 17 is the rod 14
A pressing plate is fixed to the rear end, and this pressing plate is always fitted to the rear end of the holder 10 with a small gap 18 therebetween. Reference numeral 19 denotes a projecting portion integrally provided downward from a part of the holder 10, and a water injection hole 20 communicating with the opening 15 is provided in this projecting portion. A spiral portion 21 is formed on the circumferential surface of the protrusion 19 .
Reference numeral 22 denotes a cylinder case with a carbon dioxide gas cylinder 23 built therein, and a spiral part 24 is formed on the upper peripheral surface of this cylinder case, and this spiral part 24 is screwed into the spiral part 21 of the protruding part 19 and tightened. It becomes like this. 25 is the mouth part 2 of the carbon dioxide gas cylinder 23
3' breaking needle 26 and feed hole 27 adjacent to this needle.
This cap is placed on the cylinder 23 when the cylinder case 22 is screwed onto the protrusion 19.

First, when making carbonated water, fresh water is stored in the container 1 and the lid 4 is sealed. After that, in order to screw the cylinder case 22 containing the carbon dioxide gas cylinder 23 into the protrusion 19 of the holder 10,
After placing the cap 25 on the upper surface of the mouth of the cylinder 23, it is screwed onto the protrusion 19. Then, the needle 26 protruding from the lower end of the cap 25 gradually breaks the opening 23' of the cylinder 23, and the cylinder case 2
2 is completely screwed into the protrusion 19, the cylinder opening 23' is completely torn, and carbon dioxide gas leaks from the supply hole 27 adjacent to the needle 26 and flows from the water injection hole 20 of the protrusion 19. Vertical hole 16 → opening 15 → space 11
→It comes to be supplied to the inside of the vessel 1 from the tube 9 through the through hole 8. On the way, the cylinder 13 whose opening 15 is pressed by the bullet 12 is opened by gas pressure. In this way, part of the carbon dioxide gas is absorbed and dissolved in the water, and the rest remains as gas pressure inside the vessel and is used as pressure to push out the carbonated water (see Figure 1). After the supply of carbon dioxide gas in the cylinder 23 is finished, the cylinder case 22 is unscrewed and the protrusion 1 is removed.
The water injection hole 20 of No. 9 is exposed.

In addition, after supplying carbon dioxide gas, the cylinder case 22
You can carry the container without removing it, using the case as a handle.

Next, when using carbonated water, when you lightly press your thumb against the pressing plate 17, the bullet 12 contracts and a flow path is created between it and the cylinder 13 that had closed the opening 15. Due to the gas pressure inside the vessel, the passage from the tube 9 to the through hole 8 → the space 11 → the opening 15 → the vertical hole 1
6 and is then poured out of the vessel from the water injection hole 20 (see Fig. 2).

Moreover, if the remaining beer or Chu-Hi is stored in the container 1 and carbon dioxide gas is supplied, the beer or Chu-Hi is returned to the original state again, so it can be drunk while being stored in the container.

Also, when you want to clean the dirt on the inner wall of the container body 1, remove the lid body 4 and open the wide-diameter mouth part 2.
You can just put your hands in it.

3. Effects of the invention In this way, the present invention has a part of the container body 1 which is entirely cylindrical in shape, has a wide opening, and is screwed and sealed with a lid body equipped with a knob equipped with a safety valve. A tube 9 is installed inside the through hole 8 of the external connection tool 7 provided.
A holder 10 is connected to the outside of the holder, and a pressing plate 17 is provided by protruding the end of the rod 14 of the cylinder 13 that presses against the bullet 12 provided inside the holder, and is integrated with the holder. A water injection hole 20 communicating with the through hole 8 is provided in the downwardly protruding portion 19 provided at the bottom, and a cylinder case 22 containing a carbon dioxide gas cylinder 23 is connected to a needle 26 that breaks the opening 23' of the cylinder case 22 and a hole 27 for supplying gas. Since this carbonated water maker is characterized in that it is removably attached to the protruding portion with a cap 25 interposed therebetween, the following effects can be achieved.

First, carbon dioxide gas can be supplied into the fresh water of the vessel by a simple means, and moreover, the supply can be carried out reliably. Furthermore, carbonated water can always be poured quickly and reliably.

Second, there is no need to install a special handle on the container body for carrying the container, and the cylinder case can be reliably used as a handle with the cylinder case attached.

Thirdly, since the opening of the vessel has a wide diameter, dirt on the vessel wall can be cleaned reliably and quickly by hand.

Fourth, the overall structure is relatively simple and concise, so manufacturing costs can be reduced.
