Burner with oxygen shortage sensor

A petroleum burner comprising:

• an outer housing containing a fuel tank and having a front opening above said tank;
• a wick for sucking up fuel stored in said tank, said wick being able to be moved by operation of a knob between an upper burning position and a lower extinguishing position;
• a combustion cylinder, located over said tank and opposite to the front opening portion, for burning fuel evaporated from said wick;
• a casing located directly above said combustion cylinder and said wick and attached on a lower surface of a roof plate of said outer housing, said casing having a lower opening;
• an oxygen shortage sensor employing tin oxide located in said casing and producing a detecting signal representative of an oxygen shortage;
• a baffle member provided in said casing and positioned in said opening for preventing direct intrusion of air from a periphery of said opening of said casing from impinging directly on said oxygen shortage sensor and affecting the detecting signal;
• and
• a control unit responsive to said detecting signal for generating a control signal to operate at least one of an external alarm means and a combustion-stopping means in response to said oxygen shortage sensor detecting a shortage of oxygen.
