The utility model relates to the technical field of cleaning, and provides a powder chamber gun barrel and gun body powder cleaning device which comprises a powder chamber, a sliding groove is formed in the side face of the powder chamber, a bottom moving seat is arranged on the side face of the powder chamber, a sliding plate is connected to the top of the bottom moving seat in a sliding mode, and an adjusting device is arranged on the sliding plate. According to the utility model, when the motor is started, the output shaft of the motor drives the threaded rod to rotate, and the threaded rod is in threaded connection with the threaded sleeve, so that the rotation of the threaded rod is converted into the linear movement of the threaded sleeve. And movement of the threaded sleeve further drives the moving plate, the connecting plate, the connecting column, the fixing block and the powder spraying gun to integrally conduct lifting motion, the powder spraying gun moves up and down and left and right, the powder spraying gun can be moved out of the powder room to be cleaned, and through the technical scheme, the technical problem that the powder spraying gun cannot be cleaned in the related technology is solved.

This invention discloses a fuel atomization system suitable for the combustion chamber of a regenerative micro gas turbine, comprising: a T-shaped evaporator, a swirling oil-gas duct, a coaxial atomizing nozzle, an air intake pipe, and a fuel line protection sleeve; the T-shaped evaporator, the swirling oil-gas duct, and the coaxial atomizing nozzle are arranged coaxially, the air intake pipe is eccentrically connected to the side wall of the coaxial atomizing nozzle and can introduce high-pressure gas from the section before the regenerator after the compressor, the initially atomized mixed oil and gas enters the swirling oil-gas duct for further atomization and then evaporates and is ejected through the T-shaped evaporator, the fuel line protection sleeve is coaxially arranged on the outside of the swirling oil-gas duct and the coaxial atomizing nozzle and can avoid the direct impact of high-temperature backflow gas on the coaxial atomizing nozzle. This invention can significantly optimize fuel atomization quality, shorten the combustion chamber length, improve combustion efficiency, and improve the uniformity of combustion chamber outlet temperature distribution by adding a coaxial atomizing nozzle and an air intake pipe upstream of the traditional evaporator.

A liquid ejection head capable of ensuring stable ejection characteristics is provided. A liquid ejection head according to one embodiment includes an actuator portion, a nozzle plate, and a throttle portion. The actuator portion has grooves that constitute a plurality of pressure chambers and a plurality of side walls formed between the grooves that constitute the pressure chambers. The nozzle plate is disposed opposite one side of the plurality of pressure chambers. The throttle portion has a throttle wall that blocks a portion of a communication port of the pressure chamber of the actuator portion that communicates with the common chamber and forms a throttle port in which the width of the one side is reduced in the depth direction of the pressure chamber.
