Abstract

The present invention provides a pump, which includes a main body (20), a ball body (30), a main rod (40), a piston (50), and a piston tube (60) and an elastic component (70). The main body (20) includes an installation hole (22), a valve hole (23) opposite to the installation hole (22) and a valve chamber (24) communicating with the installation hole (22) and the valve hole (23). The ball body (30) is arranged inside the valve chamber (24) and can be used to close the valve hole (23). The main rod (40) passes through the installation hole (22) and can press against the ball body (30). The piston (50) sleeves the main rod (40) and contacts firmly with the valve chamber (24). The piston tube (60) sleeves the main rod (40) and is close to the piston (50). The elastic component (70) is arranged inside the valve chamber (24) and is used to provide a constant force to the main rod (40) to allow the main rod (40) and the piston (50) move away from the ball body (30). When the user presses the piston tube (60), the main rod (40) and the piston (50) move towards the valve hole (23), and the main rod (40) can press against the ball body (30) to close the valve hole (23).
