Description

Mixed water tap with quantity control function The present invention relates to a mixing faucet having a water volume control function that can be applied to washbasins, showers, and sinks. Generally, a mixing faucet is installed in a sink or bathtub to selectively discharge hot or cold water, or to discharge a mixture of both. This mixing faucet consists of a main body formed to supply cold and hot water respectively from cold and hot water pipes, and a lever installed on the main body to control the water flow and select between cold and hot water. A mixing faucet allows the user to select cold or hot water, adjust the temperature, and shut off or supply water by grasping and rotating or raising the lever. To use a mixing faucet, the amount of water is controlled by opening and closing the lever, and in cases where hot and cold water are dispensed from a single faucet fitting, the water temperature is controlled by adjusting the rotation angle of the lever. A 'mixing faucet assembly' is disclosed in Korean Registered Utility Model No. 20-0497648. Meanwhile, referring to FIG. 5, the mixing faucet is configured such that when water is turned on by operating the handle (11), the shut-off member (31) installed inside the case (30) opens, and cold and hot water are mixed in the shut-off member (31) through the cartridge (33) connected to the high-pressure hose, and then the mixed water is discharged to the outside through the cartridge (33) and the mixed water discharge hose (not shown). The on/off state and flow rate of water can be controlled by adjusting the up and down angle of the handle, and the amount of cold and hot water mixed can be controlled by adjusting the appropriate left and right rotation angle. Meanwhile, conventionally, the handle was unintentionally adjusted to an excessive angle, which resulted in excessive discharge of water, causing water to splash onto clothes or lead to water waste. FIG. 1 is a perspective view of a mixing faucet having a water volume control function according to the present invention. FIG. 2 is a plan view showing a ‘lever angle setting part’ in a mixing faucet having a water volume control function according to the present invention. FIG. 3 is a side cross-sectional view showing an ‘overpressure warning unit’ in a mixing faucet having a water volume control function according to the present invention. FIG. 4 is a plan view showing a ‘locking part’ in a mixing faucet having a water volume control function according to the present invention. Figure 5 is a drawing showing a conventional mixing water tap. Preferred embodiments are described in detail below based on the attached drawings. The embodiments described below are intended to provide a detailed description sufficient for a person skilled in the art to easily practice the invention, and do not imply that the technical scope and concept of the invention are limited thereby. In addition, the size or shape of the components shown in the drawings may be exaggerated for clarity and convenience of explanation, and terms specifically defined in consideration of the configuration and operation of the present invention may vary according to the intent or convention of the user or operator, and it should be noted that the definitions of such terms must be based on the content throughout this specification. Among the attached drawings, FIG. 1 is a perspective view of a mixing faucet having a water volume control function according to the present invention, FIG. 2 is a plan view showing a 'lever angle setting part' of a mixing faucet having a water volume control function according to the present invention, FIG. 3 is a side cross-sectional view showing an 'overpressure warning part' of a mixing faucet having a water volume control function according to the present invention, and FIG. 4 is a plan view showing a 'locking part' of a mixing faucet having a water volume control function according to the present invention. The mixing faucet having a water volume control function according to the present invention is configured such that when water is turned on by operating the valve handle (110), the shut-off member (230) installed inside the case (210) opens, and cold and hot water are mixed in the shut-off member (230) through the cartridge (200) connected to the cold and hot water hoses (L1, L2), and then the mixed water is discharged to the outside through the mixed water discharge port (150) after passing through the cartridge (200). The cartridge (200) includes a case (210), a stopper member (230) formed within the case (210), and a lever (23) connected to the stopper member (230) and coupled to the valve handle (110). A through hole (250) is formed in the upper plate of the above case (210) to which a lever (23) is coupled. It also includes a lever angle setting part (300) formed on the upper plate of the case (210) to move the lever (23) by a certain angle and to rotate the lever (23) in steps so that the lever (23) opens
