    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

    [0017] The purpose, construction, features, functions and advantages of the present invention can be appreciated and understood more thoroughly through the following detailed descriptions with reference to the attached drawings.

    [0018] Refer to FIGS. 1 to 3 respectively for a schematic diagram of a pressure stabilization structure having a built-in integrally formed booster pump according to the present invention; a cross section view of a pressure stabilization structure having a built-in integrally formed booster pump according to the present invention; and a partial enlarged view of the upper portion of a pressure stabilization structure having a built-in integrally formed booster pump shown in FIG. 2 according to the present invention.

    [0019] As shown in FIGS. 1 to 3, the present invention provides a pressure stabilization structure having a built-in integrally formed booster pump, comprising: a booster pump 1, a valve body 2, a high pressure chamber 3, and a low pressure chamber 4. The valve body 2 is formed integrally with a shell of the booster pump 1; on the valve body 2 is disposed a pressure release water input port and a pressure release water output port; a main valve core is disposed in an inner chamber of the valve body 2, that is movable to control the opening size of the pressure release water output port; and an auxiliary valve core is disposed in the inner chamber of the valve body 2, that is retractable to control the opening size of the pressure release water input port. The high pressure chamber 3 is disposed on the booster pump 1 and is connected to a water output end of the booster pump 1, and is connected to the pressure release water input port disposed on the valve body 2. The low pressure chamber 4 is disposed on the booster pump 1, and is connected to the high pressure chamber 3 through the valve body 2, the low pressure chamber 4 is connected to the pressure release water output port disposed on the valve body 2, and is connected to a water input end of the booster pump 1.

    [0020] In an embodiment of the present invention, the main valve core includes a pipe piece 5, that is connected to the inner chamber of the valve body 2 through threads, and an inner chamber of the pipe piece 5 is a water flow channel; and a water input end of the pipe piece 5 is disposed facing the auxiliary valve core, while a water output end of the pipe piece 5 is disposed facing the pressure release water output port.

    [0021] In an embodiment of the present invention, the auxiliary valve core includes: a spring 6; and a piston 7, pressed and connected on the main valve core. Wherein one end of the spring 6 is fixed in the inner chamber of the valve body 2, while one other end of the spring 6 is fixed in a guiding slot of the piston 7.

    [0022] In an embodiment of the present invention, the size of the inner chamber of the valve body 2 is fit for receiving the pipe piece 5 and the piston 7, and it provides a space sufficient for them to move therein.
