PROBLEM TO BE SOLVED: To disclose a device for indoor sterilization and dust removal and an apparatus for increasing oxygen content of air. [Solution] An oxygen production chamber is installed in the body, an ejection chamber is installed on a left side wall of the oxygen production chamber, and a top chamber is installed on a top wall of the ejection chamber. A driving chamber is installed on the upper side of the chamber, and an oxygen manufacturing device capable of manufacturing oxygen is installed between the driving chamber, the oxygen manufacturing chamber, and the top chamber. A large amount of oxygen is produced under the action, and the purity of the produced oxygen is high at the same time, and the device can control the contact amount of the hydrogen peroxide solution and manganese oxide through the up and down movement of the oxygen production device, thereby The rate is controlled, which eliminates the need for the patient to wear an oxygen mask and inhale oxygen. [Selection diagram] Figure 1【課題】本発明は室内用の殺菌除塵と空気の酸素含有量を増やす装置を開示した。【解決手段】ボディーを含み、前記ボディーの中には酸素製造チャンバが設置され、前記酸素製造チャンバの左側壁には弾き出しチャンバが設置され、前記弾き出しチャンバの頂壁には頂部チャンバが設置され、前記酸素製造チャンバの上側には駆動チャンバが設置され、前記駆動チャンバと前記酸素製造チャンバと前記頂部チャンバとの間には酸素を製造できる酸素製造装置が設置され、本装置は過酸化水素水が酸化マンガンの触媒作用のもとで大量の酸素を作り出し、同時に作り出した酸素の純度が高く、装置が酸素製造装置の上下移動を通じて過酸化水素水と酸化マンガンとの接触量を制御でき、これにより酸素の生成の速度を制御し、これにより患者が酸素マスクをつけて酸素を吸入する必要がなくなる。【選択図】図１
