The invention provides a hard pressurizing
oxygen chamber and belongs to the field of
hyperbaric oxygen chambers. According to the technical purposes, a seal door can be sealed with a main chamber body through an air cylinder, the sealing effect is better, and insiders easily operate on the
oxygen chamber by using internal and external double operation panels. In order to achieve the technical purposes, the hard pressurizing
oxygen chamber comprises the main chamber body and a power case, the pull-push type seal door is arranged on the side wall of the main chamber body, and the seal door is sealed with the main chamber body through the air cylinder. The main chamber body is provided with a controller, one operation panel is arranged on the outer side of the controller, and the
control circuit board is arranged in the controller. The main chamber body is internally provides with a temperature sensor and a
pressure sensor, the main chamber body is connected with the
control circuit board, the power case is internally provided with an
air compressor, an oxygen generator and a
refrigeration dryer, the main chamber body is provided with gas inlets, and the power case is correspondingly provided with gas outlets, and each gas outlet is separately connected with the
air compressor and the oxygen generator.
