The utility model discloses a power bank with a telescopic line structure, which relates to the technical field of power banks, and comprises a shell, the top end of the shell is covered with a top cover, one side of the shell is provided with a charging head and a charging line, the shell is internally provided with a storage disc, the storage disc is internally provided with a telescopic assembly, and the telescopic assembly is connected with the charging head and the charging line. The telescopic assembly comprises a center pipe, a lifting rod, a moving rod, a spring, a connecting line, a fixing clamping piece and a handle rope. According to the power bank with the telescopic line structure, the telescopic assembly is arranged, four springs are used for replacing a single metal elastic piece in the prior art, elastic stretching and retracting of the charging line are achieved, the service life of stretching and retracting of the charging line can be effectively prolonged, and the stretching and retracting effect can be guaranteed; according to the portable power bank, a user can conveniently carry the portable power bank to hook or carry the portable power bank, and the portable power bank can be pulled out for charging only by pulling the handle rope upwards to drive the four moving rods to retract inwards, so that the use functions of the portable power bank are enriched, and the use experience is improved.

This utility model belongs to the field of hydrogen fuel cell technology and relates to an ejector assembly with a pressurization function. It includes an ejector body, a return valve body installed on the top of the ejector body, and the inner cavity of the return valve body communicating with the return port at the top of the ejector body. A turbine fan is rotatably mounted inside the return valve body to compress the fuel cell return gas flowing back to the return valve body. A solenoid valve is installed at the inlet end of the ejector body, and a nozzle is installed on the solenoid valve. The nozzle extends into the mixing chamber of the ejector body, and the nozzle outlet extends to the gas channel inlet end of the ejector body. This assembly can effectively improve the intake efficiency of the return hydrogen gas, and has high structural reliability and is easy to maintain.

The utility model belongs to the technical field of packaging mechanical equipment, and relates to a weighing hopper structure which comprises a weighing cylinder and a discharger arranged at the top of the weighing cylinder in a matched mode, and a discharger driving motor is installed on one side of the discharger so as to drive a discharger discharging valve to rotate and control the discharging end of the lower portion of the discharger to be opened and closed. A baffle is arranged on the top of the weighing cylinder corresponding to the closed side of the discharging valve of the discharger, a clamping groove in the lower portion of the baffle is clamped on a frame plate on the top of the discharger and fixed through a bolt, and the upper portion of the baffle is provided with a folding portion so that when the discharging valve of the discharger is closed, materials blocked by the discharging valve of the discharger can fall into the weighing cylinder after being folded. According to the hopper structure, in the closing process of the discharging valve, materials can be effectively collected, and the materials are prevented from splashing into a workshop.
