Description

[Technical Field]

[0001] The present invention relates to a flow path diversion valve, which can supply a specific gas from a location that provides a specific gas to a location that requires a specific gas at a constant concentration, or can allow the specific gas to flow out, or can supply a specific gas to a location that requires a specific gas at a constant concentration and block the flow of the specific gas to the outside. [Background technology]

[0002] As society develops, there is a phenomenon in which people become materially richer while emotionally poorer.

[0003] Therefore, they welcome companion animals into their family to provide emotional stability.

[0004] Because these companion animals are living beings, it takes a lot of effort and money to keep them alive.

[0005] The most important issue here is the health of companion animals.

[0006] However, in the case of ordinary pet owners who are not experts on pets, it is currently difficult to grasp the health status of their pets in detail.

[0007] Also, if your pet's illness becomes severe, you can take it to the veterinary hospital, but it can be difficult to visit the veterinary hospital every time it shows minor symptoms.

[0008] Therefore, when the health condition of a companion animal is in doubt, a chamber is needed to care for the companion animal so that its health condition can improve or prevent further deterioration.

[0009] Oxygen (O2) therapy is commonly used to care for companion animals, and a constant oxygen concentration is required for such therapy.

[0010] However, if oxygen is continuously supplied to the chamber from an oxygen tank or oxygen generator, excessive oxygen concentration in the chamber may cause non-therapeutic side effects in the pet.

[0011] Therefore, a flow channel switching valve is required that can switch the flow channel so that oxygen supplied from an oxygen tank or oxygen generator can flow into or out of the chamber depending on the oxygen concentration in the chamber, thereby maintaining a constant oxygen concentration in the chamber. Summary of the Invention [Problem to be solved by the invention]

[0012] The problem to be solved by the present invention is to provide a flow path switching valve that can supply a specific gas from a location that provides a specific gas to a location that requires a constant concentration of the specific gas, or that can flow out to the outside, or that can supply a specific gas to a location that requires a constant concentration of the specific gas and block out flow out to the outside, thereby maintaining a constant concentration of the specific gas in the location where the specific gas is to be supplied.
