Description

Technical Field

[0001] This utility model relates to a push-button shower faucet, and in particular to a flow regulating valve located between the mixing section and the dispensing section. Background Technology

[0002] The existing technology, Chinese patent 202111216651.0, describes a shower mechanism and faucet with automatic reset via button linkage. It includes a body and a control mechanism. The body has a water inlet channel, at least two water outlet channels, a main valve core, and button-type switch valve cores corresponding to each water outlet channel. The control mechanism includes button modules connected to the button-type valve cores, a drive component connected to the main valve core, and a linkage rod slidably connected to the body. Each button module has a first elastic reset component and a first hook. The linkage rod has a second hook and a second elastic reset component for engaging the second hook with the first hook of the pressed button module. The drive component is movably connected to one of the button modules. When the drive component drives the main valve core to block the water inlet channel, it drives the connected button module to open the corresponding water outlet channel via the button-type switch valve core. The problem is that it can only adjust the hot and cold water ratio, not the water flow rate.

[0003] Chinese Patent CN200920150796.3 discloses a water proportional valve assembly, including a valve body with a water flow channel within it, and an inlet and outlet communicating with the water flow channel on the valve body. It also includes a valve core with a valve core hole, adjustable in flow rate, located within the water flow channel, and a spindle fixed at one end to the valve core. The key feature is the presence of a valve core hole on the valve core. Furthermore, it includes a housing fixedly connected to the valve body, a rotatable internal gear located within the housing, and a motor mounted on the housing. A sealing ring is provided between the housing and the valve body, and the other end of the spindle is fixed to the internal gear. A sealing ring is also provided between the spindle and the housing. Additionally, it includes an external gear located within the internal gear, meshing with it, and the motor drives the external gear to rotate. It also includes a water flow sensing component located within the water flow channel and at the inlet, and a Hall effect sensor fixed outside the valve body. Finally, it includes a circuit board located within the housing and a permanent magnet on the internal gear. The problem is its complex structure, requiring a rotary knob for operation.
