Description

[Technical field]

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

[0002] As society develops, the phenomenon of people becoming materially richer while at the same time becoming emotionally poorer is occurring.

[0003] Therefore, they are welcoming companion animals into their family to help them feel more emotionally stable.

[0004] These companion animals are living beings and require a lot of effort as well as financial costs to keep them alive.

[0005] Here, the most important issue is the health of companion animals.

[0006] However, in the case of ordinary pet owners who are not experts on companion animals, the current situation is that they are unable to grasp the detailed health conditions of their pets.

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

[0008] Thus, when the health of a companion animal is in doubt, a chamber is needed to care for the companion animal so that its health condition improves or prevents it from worsening further.

[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 concentrations in the chamber may cause non-therapeutic side effects in companion animals.

[0011] Therefore, a flow path switching valve is required that can switch the flow path 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 the 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.

[0013] The problems to be solved by the present invention are not limited to those mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the following description. [Means for solving the problem]

[0014] In order to achieve the above object, the present invention provides a flow path diversion valve, which includes a valve body having an inlet pipe and first and second outlet pipes on one side, and including an inlet hole corresponding to one end of the inlet pipe and first and second cam receiving grooves corresponding to one end of each of the first and second outlet pipes, first and second cams received in the first and second cam receiving grooves, respectively, to block the outflow of a specific gas, a cam disc including first and second cam compression protrusions for compressing at least one of the first and second cams to divert the flow path of the specific gas, and a first or second cam compression protrusion for compressing one of the first or second cams to block the outflow of the specific gas, a cover that covers the cam disc and is coupled to the valve body, and a motor provided on the cover to rotate the cam disc to divert the flow path of the specific gas. The motor can redirect the flow path of the specific gas to discharge the specific gas to the outside when the concentration of the specific gas in the place where the specific gas is supplied is higher than a set value, and can redirect the flow path of the specific gas to discharge the specific gas to the place where the specific gas is supplied when the concentration of the specific gas in the place where the specific gas is supplied is lower than a set value.

[0015] The flow path diversion valve may include first and second cam springs that are received in the first and second cam receiving grooves, respectively, and receive portions of the first and second cams to provide elastic force to the first and second cams, respectively.

[0016] The flow diversion valve is fitted to the shaft of the motor and may include a sealing O-ring provided between the cam disc and the cover.
