Abstract: A downhole throttling device based on wireless control includes an inlet nozzle, a throttling assembly, an electrical sealing cylinder, a gas guide cylinder, a lower adapter sleeve, an end socket, a female sleeve, and electrical components. The inlet nozzle is connected to the throttling assembly, the throttling assembly is connected to the electrical sealing cylinder and the gas guide cylinder, the electrical sealing cylinder and the gas guide cylinder are both connected to the lower adapter sleeve, the lower adapter sleeve is respectively connected to the end socket and the female sleeve, and the electrical components are arranged in the electrical sealing cylinder. A throttling effect is achieved by detecting the temperature and pressure in a tube by a temperature/pressure sensor in the electrical components and controlling a motor to rotate a movable valve in the throttling assembly by a circuit control assembly, thereby achieving wireless control over downhole throttling.

Abstract: The present invention relates to a processing cartridge, comprising a developing unit and a photosensitive unit, of which the latter consists of a photosensitive member and a developer chamber and has a developer outlet connecting the chamber and a sealing cap matching the developer outlet and used to seal the said outlet. Based on the said technical proposal, the photosensitive unit is designed with a developer outlet connecting the chamber and with a sealing cap matching the developer outlet and used to seal the said outlet, so, when the photosensitive unit becomes full with developer, the sealing cap can be opened to remove the developer in the photosensitive unit, which facilitates the cleaning without affecting the normal operation of the processing cartridge.
