Chamber adaptor and manufacturing method thereof

A chamber adaptor, comprising a housing provided with a gas inlet, a gas outlet, a chamber inlet, and a chamber outlet;

• wherein:
• the gas inlet is configured to be removably connected to a main board device, the main board device is configured to provide oxygen and compressed air to the chamber adaptor, the gas outlet is configured to be removably connected to a respiratory pathway, the chamber inlet is configured to be removably connected to an input end of a chamber for storing liquid and the chamber outlet is configured to be removably connected to an output end of the chamber;
• the chamber adaptor further comprises a control circuit having a first end and a second end that are opposite to each other, and a distance between the first end and the second end is a total length of the control circuit;
• wherein the at least one sensing apparatus is provided at the first end of the control circuit and extends into a gas output channel formed between the gas outlet and the chamber outlet, the space defined by an inner wall of the gas output channel only comprises the at least one sensing apparatus, and the at least one sensing apparatus is configured to detect a temperature of the gas passing through the gas output channel;
• wherein a second end of the control circuit is electrically connected to the main board device, and the control circuit is configured to deliver the temperature detected by the at least one sensing apparatus to the main board device;
• wherein a first supporting element, a second supporting element, and a third supporting element are formed on the control circuit, and the first supporting element, the second supporting element, and the third supporting element are all in contact with a surface of the control circuit, so as to improve a strength of the control circuit and support the circuit board within a mold of the chamber adaptor to prevent the control circuit from warping.
