[0002] In building water supply and drainage systems, faucets, as terminal water-using devices, directly affect water resource utilization efficiency due to their water-saving performance and ease of use.

[0003] Existing faucets have the following shortcomings: most faucets only have a single opening and closing control function, and cannot accurately adjust the water flow according to actual water demand, resulting in serious water waste in unnecessary high-flow water use scenarios and poor water-saving effect; some faucets with integrated flow adjustment function have their flow adjustment mechanism and opening and closing control mechanism designed as one unit, which are prone to mutual interference during operation; some faucets have complex structures, are difficult to assemble and maintain, and are not conducive to widespread application.

[0004] Existing faucets have poor water-saving performance, interference between flow regulation and on / off control, poor sealing performance, and are inconvenient to maintain. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This application provides a water-saving building water supply and drainage device that solves the problems of poor water-saving effect, mutual interference between flow regulation and on / off control, poor sealing performance and inconvenient maintenance of existing faucets. It realizes independent operation of flow regulation and on / off control, improves water-saving effect and ease of use, and optimizes sealing structure and assembly method to reduce maintenance costs.

[0026] This utility model discloses a water-saving building water supply and drainage device.

[0027] According to the appendix Figures 1-6 As shown, this is a faucet, including a valve body 1, a valve core 2, and a water inlet pipe 3. These components work together to achieve water supply, flow regulation, and on / off control functions.

[0028] Furthermore, the valve core 2 is inserted into the inner side of the valve body 1 and is the core component for realizing flow regulation and opening and closing. It includes a throttle valve 21 and an opening and closing valve 22. The opening and closing valve 22 is fixed to the top of the throttle valve 21 by a threaded connection. The two are coaxially arranged to ensure smooth water flow. The core function of the throttle valve 21 is to control the water flow rate of the faucet, while the opening and closing valve 22 is used to control the overall opening and closing state of the faucet.

[0029] Furthermore, to achieve precise flow regulation, a ball core 213 is inserted into the inner side of the throttle valve 21. The ball core 213 has a hollow structure and a flow regulation hole on its side wall. A connecting rod 214 is integrally formed on one side of the ball core 213. The connecting rod 214 extends horizontally through the side wall of the throttle valve 21 to the outside of the device. A knob 211 is sleeved on the outer part of the connecting rod 214. The knob 211 has a threaded hole along the radial direction. A connecting bolt 212 is inserted into the threaded hole. The connecting bolt 212 passes through the knob 211 and is inserted into a pre-set positioning hole on the outer side of the connecting rod 214 to achieve a fixed connection between the knob 211 and the connecting rod 214. When the knob 211 is rotated, the ball core 213 can be rotated inside the throttle valve 21 through the connecting rod 214. By adjusting the overlapping area of ​​the flow hole on the ball core 213 and the water inlet channel of the throttle valve 21, continuous and precise regulation of the outlet flow rate can be achieved.

[0030] Specifically disclosed, the valve housing 1, serving as a support and protective component of the device, includes a plug-in housing 11, a valve handle 12, and a fixing ring 13. The valve handle 12 is installed above the plug-in housing 11 and is used to control the opening and closing of the valve 22. The fixing ring 13 is sleeved on the outside of the plug-in housing 11. A positioning ring 111 is integrally formed on the outside of the plug-in housing 11. The positioning ring 111 is located above the fixing ring 13. During installation, the fixing ring 13 and the positioning ring 111 cooperate to securely fix the plug-in housing 11 in the preset mounting hole in the wall or mounting platform, preventing the device from becoming loose.

[0031] Specifically disclosed, a water outlet pipe 112 is welded to the outside of the plug-in housing 11. The water outlet end of the water outlet pipe 112 is threadedly connected to an aerator 113. The aerator 113 is a conventional bubble generating component that can mix air into the water flow to form bubble water. While ensuring the visual flow rate and the feel of use, it reduces the actual water flow rate and further enhances the water-saving effect. A sealing ring 114 is glued to the inside of the plug-in housing 11. The sealing ring 114 is made of aging-resistant rubber material and is used to improve the sealing performance between the opening and closing valve 22 and the plug-in housing 11 to prevent water leakage.

[0032] It is particularly important to emphasize that the inner side of the valve handle 12 is connected to the sleeve 121 by an interference fit. The sleeve 121 is made of metal to enhance the structural strength. The top of the opening and closing valve 22 has an integrally formed insert rod 221, which is inserted into the inner side of the sleeve 121 and the two are connected by a flat key to ensure that the valve handle 12 can drive the insert rod 221 to rotate synchronously. The opening and closing valve 22 adopts a conventional ceramic sealing plate structure. The insert rod 221 drives the sealing plate to rotate, realizing the contact and separation of the sealing surface, thereby controlling the water flow. At the same time, the opening and closing valve 22 is inserted into the inner side of the insert shell 11, and its top forms a gap seal with the sealing ring 114, further improving the sealing reliability.

[0033] It is particularly important to emphasize that a nut 31 is fitted on the outside of the water inlet pipe 3, and one end of the water inlet pipe 3 is inserted into the water inlet of the throttle valve 21. A rubber sealing ring is provided at the joint between the two to enhance the sealing performance. The nut 31 is used to fix the water inlet pipe 3 to the external water supply pipeline to ensure a stable water supply.

[0034] Working principle:

[0035] 1. Opening and Flow Regulation: Rotate valve handle 12, which drives insert rod 221 to rotate through sleeve 121, causing the ceramic sealing plate of opening and closing valve 22 to separate, and water flows through inlet pipe 3 into throttle valve 21; according to water demand, rotate knob 211 clockwise or counterclockwise, which drives ball core 213 to rotate through connecting rod 214, adjusting the overlapping area of ​​flow hole of ball core 213 and water inlet channel of throttle valve 21 to increase or decrease flow rate; water flows through throttle valve 21 and opening and closing valve 22 into the inner cavity of plug shell 11, and finally flows out from aerator 113 of outlet pipe 112 to form aerated water.

[0036] 2. Closing: Rotate valve handle 12 in the reverse direction to drive the plug rod 221 and the sealing plate of the opening and closing valve 22 to rotate, so that the sealing plate is in contact, cut off the water flow, and complete the closure.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
