Problems solved by technology

The door and window automatic closing system mainly uses its function of kinetic energy storage. When opening the door or window, the work done to the door or window is stored in the system inner spring and converted into elastic potential energy. When you let go and stop opening the door or window, the elastic potential energy quickly Release, the doors and windows close quickly, but it is easy to generate a lot of noise and certain damage
The sustained-release effect of these two kinds of impulse sustained-release devices is not ideal enough

Abstract

The invention relates to an impulse slow-releasing technology and discloses an impulse slow-releasing device. The impulse slow-releasing device comprises a cylinder body provided with an upper cylinder hole and a lower cylinder hole; an upper piston is matched inside the upper cylinder hole in a sealed manner; a piston rod is connected with the upper part of the upper piston; an upper oil cavity is formed by the bottom of the upper piston and the upper cylinder hole; a lower piston is matched inside a lower cylinder hole in the sealed manner; a lower oil cavity is formed by the top of the lower piston and the lower cylinder hole; a lower end cover is threaded connection with the bottom of the lower cylinder hole; a potential storage slow-releasing spring is arranged between the lower piston and the lower end cover; an air vent is formed in the lower end cover; a cylinder base is arranged between the upper cylinder hole and the lower cylinder hole; a step-shaped vertical hole and a step-shaped bending hole, which are communicated with the upper cylinder hole and the lower cylinder hole, are formed in the cylinder base; a one-way valve for guiding oil from the upper oil cavity to the lower oil cavity is arranged inside the step-shaped vertical hole; and a flow adjusting valve for communicating the upper oil cavity and the lower oil cavity are arranged inside the step-shaped bending hole.

Description

technical field [0001] The invention relates to impulse sustained release technology, in particular to an impulse sustained release device. Background technique [0002] At present, common impulse slowing release devices mainly include water resistance time delay switches and automatic closing systems for doors and windows. The water-resistance time-delay switch uses its time-delay function and is mainly used in faucets and flush toilets. When the valve is pressed by hand for a moment, the valve will rebound slowly under the action of the spring and the water flow. During this process, the water flow will maintain A certain period of time, so as to realize its function. The door and window automatic closing system mainly uses its function of kinetic energy storage. When opening the door or window, the work done to the door or window is stored in the system inner spring and converted into elastic potential energy. When you let go and stop opening the door or window, the elas...
