Description

Technical Field

[0001] This utility model relates to the technical field of faucet testing machines, specifically a hot and cold water supply mechanism for a faucet life testing machine. Background Technology

[0002] The hot and cold water supply mechanism used in a faucet life testing machine is essentially a core device that provides stable water temperature and hydraulic conditions for the testing environment. It is often figuratively understood as a water tank within an intelligent circulating water supply system with dual hot and cold pools. The core components of this mechanism include a cold water tank and a hot water tank for storing low-temperature and high-temperature water respectively, a water circulation system connecting the various components, and an intelligent control system that ensures accurate water temperature and constant pressure. Its working principle involves independently controlling the water temperature in the dual tanks through built-in heating and cooling units. Then, with the help of a circulating water pump and pressure regulating device, water meeting the testing requirements is continuously delivered to the faucet under test. The outflowing water is recycled and re-injected into the tanks, forming a closed intelligent cycle. This system can accurately simulate the thermal shock, pressure fluctuations, and long-term fatigue encountered by faucets in actual use. It is crucial for objectively evaluating the lifespan and reliability of faucets and is a mature and fundamental testing and assurance device in existing technology.

[0003] However, in existing technologies, the design of such hot and cold water supply mechanisms usually focuses on the realization of their internal functions, while neglecting the safety protection of the external operation level. Specifically, during testing, an open water storage tank is often installed at the bottom of the equipment to collect splashed water. When operators approach the tank to observe the test status or adjust the equipment, the high-temperature water jets sprayed from the test nozzles at a height continuously impact the water in the tank, which can easily cause violent splashing of hot water. Since no effective isolation or shielding devices are installed on the outside of the mechanism, if the splashed high-temperature water droplets come into contact with the operator's skin, there is a safety hazard of burns, posing a potential danger to personnel safety.

[0014] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: a hot and cold water supply mechanism for a water tap life testing machine, comprising: a water tank body 1 of a dual-pool intelligent circulating water supply system, wherein a cold water outlet and a hot water outlet are installed on the water tank body 1, thereby connecting the input end of the water tap to the cold water outlet and the hot water outlet, so that water can be sprayed from the water tap; a water storage tank 19 is opened on one side of the bottom of the water tank body 1, which is used to collect the outflowing wastewater; a fixing frame 2 is symmetrically fixedly installed on one side of the water tank body 1, which provides fixed support for the entire device; each fixing frame 2 has three foldable and openable protective plates 3 longitudinally arranged inside, for protection. The protective plate 3 is made of high-temperature resistant, waterproof, and transparent material. A drive component is connected to one side of the protective plate 3. The drive component is used to drive the protective plate 3 to fold and open. By driving the protective plate 3 to fold and open, it can block one side of the water storage tank 19 for protection during the test. After the test is completed, the protective plate 3 slides upward and folds, so that the water nozzle can be disassembled. The water tank body 1 of the hot and cold dual-tank intelligent circulating water supply system is fixedly installed in the U-shaped frame 4. The U-shaped frame 4 provides fixed support for the entire device. A magnetic suction groove 5 is opened on one side wall of the U-shaped frame 4. The inner wall of the water storage tank 19 is slidably inserted into one end of the filter plate 6. The other end of the filter plate 6 passes through the U-shaped frame 4 and is fixedly connected to the magnetic suction block 7. The magnetic suction block 7 and the magnetic suction groove 5 are magnetically connected.

[0016] In use, when testing the water nozzle via the water tank body 1 of the dual-pool intelligent circulating water supply system, the water nozzle is connected and fixed to the hot water outlet and cold water outlet on the water tank body 1. The opening and closing of the water nozzle is then adjusted using a cylinder clamp to release hot and cold water. The released wastewater is collected in the storage tank 19. Simultaneously, the storage tank 19 is magnetically connected to the magnetic block 7 via a magnetic groove 5, facilitating the disassembly of the filter plate 6. During use, the filter plate 6 filters impurities from the wastewater, preventing impurities from entering. Upon reaching the water tank body 1 of the hot and cold dual-pool intelligent circulating water supply system, it affects the normal discharge of subsequent water. During the water nozzle test, the three protective plates 3 are vertically spliced ​​together, which then shield one side of the water storage tank 19, avoiding the problem of hot water splashing and creating safety hazards when operators are nearby. In addition, when it is necessary to disassemble the water nozzle, the three protective plates 3 can be moved upward and rotated into a tilted state by the drive component, thereby exposing the operation panel of the hot and cold dual-pool intelligent circulating water supply system water tank body 1, which is convenient for operators to operate. Example 2: Based on Example 1, a pump body 8 is fixedly connected to one side wall of the U-shaped frame 4 with a magnetic suction groove 5. The input end of the pump body 8 is connected to the water storage tank 19 through a suction pipe, and the output end of the pump body 8 is connected to the inside of the water tank body 1 of the hot and cold dual-tank intelligent circulating water supply system. The pump body 8 is electrically connected to an external control device, so as to facilitate the control of the pump body 8 to extract wastewater from the water storage tank 19 for recycling. A fixing block 9 is fixedly connected to the side of the fixing frame 2 near the water tank body 1 of the hot and cold dual-tank intelligent circulating water supply system. The fixing block 9 facilitates the limiting of the electric cylinder 10.

[0017] Example 3: Based on Example 2, the drive assembly includes an electric cylinder 10. The electric cylinder 10 is electrically connected to the control device mounted on the U-shaped frame 4. The bottom end of the electric cylinder 10 is rotatably connected to the fixed block 9 via a fixing pin. The top output end of the electric cylinder 10 is rotatably connected to one end of the drive plate 11 via a connecting pin. The middle part of the drive plate 11 is rotatably connected to the fixed frame 2 via a fixing pin. The other end of the drive plate 11 is fixedly connected to one side of the topmost protective plate 3. The middle and lower protective plates 3 are respectively fixedly connected to the side of the topmost protective plate 3 where the drive plate 11 is mounted. The drive plate 11 is connected to the first transmission plate 12 and the second transmission plate 13. The drive plate 11 is rotatably connected to the first transmission plate 12 through the cooperation of the first connecting plate 14, the second connecting plate 15 and the limiting pin. The first transmission plate 12 and the second transmission plate 13 are rotatably connected through the cooperation of the second connecting plate 15, the third connecting plate 16 and the limiting pin. The inner wall of the fixed frame 2 near the electric cylinder 10 is provided with a sliding groove 17. The bottom end of the third connecting plate 16 is rotatably connected to the slider 18 through the fixing pin. The sliding groove 17 limits the slider 18, and the slider 18 is slidably installed in the sliding groove 17.

[0018] In the initial state, the three protective plates 3 are folded at an angle on the top of the fixed frame 2. At this time, the output end of the electric cylinder 10 retracts. After the water nozzle is installed in the water tank body 1 of the hot and cold dual pool intelligent circulating water supply system, the controller controls the output end of the electric cylinder 10 to extend, so that the electric cylinder 10 drives the drive plate 11 to move. Under the limit of the fixed pin, the drive plate 11 drives the protective plate 3 fixedly connected to it to rotate downward. Thus, with the cooperation of the first transmission plate 12, the second transmission plate 13, the first connecting plate 14 and the third connecting plate 16, the other two protective plates 3 also rotate towards a vertical state. At the same time, with the cooperation of the slider 18 and the slide groove 17, the three protective plates 3 move downward until the three protective plates 3 are in a vertical state, blocking the water tank 19 on one side, blocking the splashing of water, avoiding hot water splashing onto the operator, and reducing safety hazards.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
