Abstract: A structure for opening a grip cover of a toy gun includes a bottom cover assembly and a rear cover assembly. The bottom cover assembly has a bottom cover covering a bottom surface of the grip and a pivot penetrating the grip and the bottom cover. One end of the bottom cover adjacent to the pivot is formed with a first hook. The rear cover assembly has a rear cover covering a rear surface of the grip. The rear cover has a protrusion connected to the grip. One end of the rear cover away from the protrusion is formed with a second hook to be engaged with the first hook. With this structure, the first hook is separated from the second hook when the bottom cover rotates downwards, thereby driving the rear cover to open rearwards by using the protrusion as a center of rotation. In this way, by only opening the bottom cover, the user can open the rear cover assembly simultaneously, thereby exchanging a pressurized gas cylinder in the grip more rapidly.

Abstract: A method for controlling a constant-pressure fluid enables an inverter with a build-in controller to control rotation speed of a pump to achieve constant-pressure control thereof. In the control method, a pressure feedback value of output flow of the pump is measured and is compared with a pressure reference value to produce an error pressure value. Afterward, an operation condition of the pump, such as an abnormal handling condition, a deceleration standby handling condition, or an acceleration condition, is determined according to the pressure error value to shut down or re-start up the pump after a delay time. Hence, the control method can avoid frequently starting up or shutting down the inverter. Therefore, the power consumption and the operation cost are reduced. The use life of the pump prolongs and constant-pressure control for the pump can be implemented.
