Portable bubble water bottle and control valve thereof
View Patent ↗A portable bubble water bottle includes a shell, a separation tank, a bottom cover, and a gas supply device. A liquid storage space and a gas supply space are individually defined on the upper and the lower sides of the separation tank. A hole is defined on the separation tank to connect the liquid storage space and the gas supply space. The gas supply device includes a gas cylinder and a control valve in the gas supply space. The opening of the gas cylinder is toward the bottom. The gas is transferred from the gas cylinder, through the control valve and the hole of the separation tank, to the liquid storage space. The invention has the advantages of increasing the dissolved gas in liquid, great safety in use, easy operation, reducing the gas escape rate, and customization in use.
1. A control valve of a portable bubble water bottle, comprising:
a main body, which has a top part, a bottom part and a middle part, wherein the top part and the bottom part are disposed opposite to each other, the top part and the bottom part are a protruding rounded flange, respectively, the middle part is disposed between the top part and the bottom part and a part of the middle part to form a rounded part, a holding space is within the main body and communicates with the rounded part by a through hole;
a path selection assembly, which has a first channel and a second channel, and the path selection assembly is disposed in the holding space of the main body;
a shell body, which has a control valve inlet, a control valve outlet, a first space and a second space, which are adjacent to each other, the control valve inlet is to communicate the first space with an outside and the control valve outlet is to communicate the second space with the outside, the main body is disposed in the first space of the shell body, and the rounded part of the main body together with the shell body form a fluid pre-storage space; and
a cover body, which is disposed corresponding to the first space of the shell body to seal the first space,
wherein the control valve outlet, the second channel and the fluid pre-storage space are in communication when the path selection assembly is in a first position,
wherein the control valve inlet, the first channel and the control valve outlet are in communication when the path selection assembly is in a second position.
2. The control valve of claim 1 , wherein the path selection assembly further comprises a connecting part, which is disposed on a side facing the cover body, while a control assembly is connected with the connecting part by passing through the cover body and a wall of the main body.
3. The control valve of claim 1 , wherein the path selection assembly has a spherical circumference.
4. The control valve of claim 3 , further comprising:
a first limit assembly, which is disposed in the holding space; and
a second limit assembly, which is disposed opposite to the first limit assembly in the holding space,
wherein the path selection assembly is disposed between the first limit assembly and the second limit assembly.
5. The control valve of claim 3 , further comprising:
a fixing assembly, which is disposed corresponding to the holding space to seal the holding space.
