The present application belongs to the technical field of inspection robots, and discloses an unlocking and door opening device, an unlocking and door opening method and an inspection robot. The unlocking and door opening device comprises a rack, a press-lock mechanism, a rotating mechanism and a door opening mechanism arranged on the rack. The press-lock mechanism can press the lock hole of a pop-up flat lock to make the rotating handle pop up. The rotating mechanism can operate the rotating handle to rotate to unlock. The door opening mechanism is used to pull the cabinet door to open the cabinet door. The unlocking and door opening device provided by the present application is used for unlocking and opening the cabinet door with a pop-up flat lock. When the rack is close to the cabinet door and faces the pop-up flat lock, the press-lock mechanism, the rotating mechanism and the door opening mechanism act in turn to realize a series of automatic control of pressing the lock to pop up the rotating handle, rotating the rotating handle to unlock and pulling the cabinet door to open the door. Thus, the remote control unlocking and door opening of the cabinet door with the pop-up flat lock are easily realized, and the execution efficiency is high, and the success rate of unlocking and door opening is high.

The invention discloses a multifunctional wireless air pulse oscillation type sputum excretion instrument. The technical problems that in the prior art, the operation range is limited, the application range is not wide, and the function is single are solved. The system comprises a main control board, a vibration fan connected with the main control board, a direct-current brushless fan connected with the main control board and used for conveying a large amount of air to the vibration fan, and a blood oxygen clamp socket, an atomization machine pump and a serial port screen which are connected with the main control board; the main control board comprises a main control chip, and a power supply circuit, a direct current brushless motor control circuit, a vibration fan control circuit, an atomization machine pump control circuit and a signal transmission circuit which are connected with the main control chip.
