Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to a new type of environmentally friendly, anti-scalding, thermostatic shower faucet. Background Technology

[0002] Shower faucets are commonly used water control devices in the bathroom industry. They are primarily used to connect hot and cold water pipes and control the water flow and temperature through adjustable components to meet the bathing needs of homes, hotels, and other scenarios. The new environmentally friendly, anti-scalding, and thermostatic shower faucets use environmentally friendly engineering materials as the core structural carrier, integrating dedicated flow channels and temperature control and water distribution components. They can achieve precise mixing of hot and cold water, constant temperature output, anti-scalding protection, and dual-outlet switching. At the same time, the optimized structural design reduces manufacturing difficulty and meets the needs of healthy, safe, and environmentally friendly use.

[0003] Most common shower faucets use a single metal shell or a simple plastic shell structure. The water flow channel and shell of traditional faucets have strong thermal conductivity. When hot water flows through, the heat is easily and quickly conducted to the surface of the shell, which poses a risk of burns to users when they come into contact with it. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a new type of environmentally friendly anti-scalding thermostatic shower faucet, which aims to improve the problem of the risk of scalding when users come into contact with it.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel environmentally friendly, anti-scalding, thermostatic shower faucet, wherein a first clamping nut is internally threaded onto the water distribution handwheel, a water distribution valve core is fixedly connected to the outer wall of the first clamping nut, a plug is fixedly connected to the outer wall of the water distribution valve core, the outer wall of the plug is fitted with a body shell, a hot water connector is internally threaded onto the body shell, an inner shell is fixedly connected to the outer wall of the body shell, a cold water connector is internally threaded onto the body shell, a thermostatic valve core is fixedly connected to the outer wall of the body shell, a second clamping nut is threaded onto the outer wall of the thermostatic valve core, a limit ring is fitted to the outer wall of the second clamping nut, a thermostatic handwheel is rotatably connected to the outer wall of the limit ring, a first water outlet connector is internally threaded onto the body shell, a second water outlet connector is internally threaded onto the body shell, and a flow channel assembly is provided inside the body shell for regulating hot and cold thermostatic water.

[0006] Through the above technical solution, hot water enters the hot water channel of the inner shell of the main body through the hot water connector, and is then transported to the thermostatic valve core through the channel integrated with environmentally friendly engineering materials. A plug seals the process hole in the inner shell of the main body, isolating the hot water inlet from the distribution valve core. Cold water enters the cold water channel of the inner shell of the main body through the cold water connector, and is then transported to the thermostatic valve core under the guidance of the channel. The hot and cold water mix within the thermostatic valve core, and the mixed thermostatic water flows through the thermostatic channel of the inner shell into the distribution valve core. Rotating the thermostatic handwheel adjusts the hot and cold water mixing ratio of the thermostatic valve core. A limit ring is also included. The adjustment stroke of the thermostatic valve core is limited to prevent the water temperature from becoming too high. After the mixed water enters the water distribution valve core, turning the water distribution handwheel drives the water distribution valve core to switch the flow channel through the tightening nut, so that the mixed water flows into the water outlet channel one or water outlet channel two of the inner shell of the main body, and is finally output through the water outlet connector one or water outlet connector two. This not only prevents the risk of scalding caused by the hot water conducting heat through the main body shell during use, thus improving the anti-scalding function, but also reduces the manufacturing difficulty of the inner shell of the main body by increasing the process holes.

[0007] Preferably, the flow channel assembly includes a cold water flow channel, which is disposed inside the body housing.

[0008] Preferably, the interior of the inner shell of the main body is provided with a constant temperature flow channel.

[0009] Preferably, the inner shell of the main body is provided with process holes.

[0010] Preferably, the inner shell of the main body is provided with a water outlet channel.

[0011] Preferably, the inner shell of the main body is provided with a second water outlet channel.

[0012] Preferably, the interior of the inner shell of the main body is provided with a hot water flow channel.

[0013] Preferably, the outer wall of the water-dividing handwheel is rotatably connected to the outer wall of the main body shell.

[0014] Preferably, the outer wall of the thermostatic handwheel is rotatably connected to the outer wall of the main body shell, and the outer wall of the water outlet connector is threadedly connected to the inside of the main body shell.

[0015] Preferably, the outer wall of the second water outlet connector is threaded to the inside of the inner shell of the main body. The inner shell of the main body is made of environmentally friendly engineering materials and does not contain lead, which is used for heavy metal leaching. This utility model has the following beneficial effects: 1. In this utility model, by allowing mixed water to flow into the water outlet channel one or water outlet channel two of the inner shell, not only is the risk of burns caused by hot water conducting heat through the outer shell during use prevented, thus improving the anti-scalding function, but the manufacturing difficulty of the inner shell is also reduced by adding process holes.

[0016] 2. In this utility model, by setting environmentally friendly engineering materials, the use of energy is reduced and carbon emissions are controlled. The thermostatic valve core is made of lead-free environmentally friendly engineering plastic, which avoids water from coming into contact with lead-containing metal materials, reduces the risk of heavy metal leaching, and makes the product healthier and more environmentally friendly during use.

Detailed Implementation

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Reference Figure 1 , Figure 2 and Figure 3An embodiment of this utility model is provided: a novel environmentally friendly anti-scalding thermostatic shower faucet, including a water distribution handwheel 1, a clamping nut 2 internally threaded to the water distribution handwheel 1, a water distribution valve core 3 fixedly connected to the outer wall of the clamping nut 2, a plug 4 fixedly connected to the outer wall of the water distribution valve core 3, a body shell 5 attached to the outer wall of the plug 4, a hot water connector 6 internally threaded to the body shell 5, a body inner shell 7 fixedly connected to the outer wall of the body shell 5, a cold water connector 8 internally threaded to the body shell 5, a thermostatic valve core 9 fixedly connected to the outer wall of the body shell 5, a clamping nut 10 externally threaded to the outer wall of the thermostatic valve core 9, a limit ring 11 attached to the outer wall of the clamping nut 10, a thermostatic handwheel 12 rotatably connected to the outer wall of the limit ring 11, a water outlet connector 13 internally threaded to the body shell 5, a water outlet connector 14 internally threaded to the body shell 5, and a flow channel assembly inside the body shell 5 for regulating hot and cold thermostatic water; Specifically, hot water enters the hot water inlet channel of the inner shell 7 through the hot water connector 6, and is then transported to the thermostatic valve core 9 through the hot water channel 20. The water distribution handwheel 1 fixes the hot water connector 6, ensuring its position does not change, and also restricts the thermostatic valve core 9, preventing its position from shifting. This causes the plug 4 to seal the process hole 17 inside the inner shell 7, isolating the hot water inlet and the water distribution valve core 3. The outer shell 5 restricts the plug 4, ensuring it does not fall out and form a seal. The shell 7 restricts the process hole 17, ensuring its position remains unchanged, thus isolating the hot water inlet from the water distribution valve core 3. Cold water enters the cold water flow channel 15 inside the inner shell 7 through the cold water connector 8, and is then transported to the thermostatic valve core 9. The outer shell 5 restricts the cold water connector 8 to prevent its position from shifting, and the cold water flow channel 15 guides the cold water to the thermostatic valve core 9, completing the cold water transport. During thermostatic operation, cold and hot water mix within the thermostatic valve core 9, and the resulting thermostatic water flows through the thermostatic flow channel 16 of the inner shell 7 into the water distribution valve. Core 3, wherein the outer shell 5 restricts the thermostatic valve core 9 to ensure that the position of the thermostatic valve core 9 does not change, and the thermostatic flow channel 16 guides the thermostatic water to flow into the water distribution valve core 3. Rotating the thermostatic handwheel 12 adjusts the hot and cold water mixing ratio of the thermostatic valve core 9. The limit ring 11 adjusts the stroke of the thermostatic valve core 9 to prevent the mixed water temperature from becoming too high. The clamping nut 10 restricts the thermostatic handwheel 12 to ensure that its position does not change during rotation, while the limit ring 11 adjusts the stroke of the thermostatic valve core 9. By restricting the temperature of the mixed water to prevent it from becoming too high, a constant temperature is achieved. After the mixed water enters the water distribution valve core 3, the water distribution handwheel 1 is rotated, which in turn drives the water distribution valve core 3 to switch the flow channel through the clamping nut 1 2, allowing the mixed water to flow into the water outlet channel 1 18 or the water outlet channel 2 19 of the inner shell 7. Finally, the water is output through the water outlet connector 1 13 or the water outlet connector 2 14. This not only prevents the risk of scalding caused by the heat conduction of hot water through the outer shell 5 during use, thus improving the anti-scalding function, but also reduces the manufacturing difficulty of the inner shell 7 by adding process holes 17.

[0021] Reference Figure 1 , Figure 2 and Figure 3The flow channel assembly includes a cold water flow channel 15, which is disposed inside the outer shell 5 of the main body. A constant temperature flow channel 16 is disposed inside the inner shell 7 of the main body. A process hole 17 is disposed inside the inner shell 7 of the main body. A first water outlet flow channel 18 is disposed inside the inner shell 7 of the main body. A second water outlet flow channel 19 is disposed inside the inner shell 7 of the main body. A hot water flow channel 20 is disposed inside the inner shell 7 of the main body. The outer wall of the water distribution handwheel 1 is rotatably connected to the outer wall of the outer shell 5 of the main body. The outer wall of the constant temperature handwheel 12 is rotatably connected to the outer wall of the outer shell 5 of the main body. The outer wall of the first water outlet connector 13 is threadedly connected to the inner shell 7 of the main body. The outer wall of the second water outlet connector 14 is threadedly connected to the inner shell 7 of the main body. Specifically, a cold water channel 15 is provided inside the outer shell 5, allowing cold water to be transported to the thermostatic valve core 9. Simultaneously, a thermostatic channel 16 is provided inside the inner shell 7, allowing thermostatic water to be transported to the water distribution valve core 3. A process hole 17 is provided inside the inner shell 7 to isolate hot water entering the water distribution valve core 3. Furthermore, an outlet channel 18 and an outlet channel 19 are provided inside the inner shell 7 to prevent mixed water from flowing into either outlet channel 18 or outlet channel 19. It will deviate; hot water is guided by a hot water flow channel 20 set inside the inner shell 7; the water distribution handwheel 1 is restricted by the outer shell 5 to ensure that its position does not change when it rotates; at the same time, the thermostatic handwheel 12 is restricted by the outer shell 5 to prevent it from falling off when it rotates; the water outlet connector 13 is restricted by the inner shell 7 to ensure that its position does not change, and the water outlet connector 14 is restricted by the outer shell 5 to ensure that its position does not change. Reference Figure 1 , Figure 2 and Figure 3 The inner shell 7 is made of environmentally friendly engineering materials and does not contain lead, which is used for the leaching of heavy metals. Specifically, the high strength of environmentally friendly engineering materials provides support, ensuring the thermostatic valve core 9 is firmly installed. Precise alignment of the thermostatic valve core 9 interface ensures the sealing and smoothness of hot and cold water mixing and flow channel switching. Its water corrosion resistance prevents aging caused by prolonged contact with water flow, ensuring stable hot and cold water flow. Combined with the outer shell 5, it achieves double-layer anti-scalding. Furthermore, the environmentally friendly engineering materials reduce energy consumption and control carbon emissions, protecting the environment. The thermostatic valve core 9 uses lead-free environmentally friendly engineering plastics, avoiding contact between water and lead-containing metal materials, reducing the risk of heavy metal leaching, and making the product healthier and more environmentally friendly during use.

[0022] Working principle: When in use, hot water enters the hot water channel 20 of the inner shell 7 through the hot water connector 6, and is then transported to the thermostatic valve core 9 through the channel integrated with environmentally friendly engineering materials. The plug 4 seals the process hole 17 of the inner shell 7, isolating the hot water inlet from the water distribution valve core 3. Cold water enters the cold water channel 15 of the inner shell 7 through the cold water connector 8, and is then transported to the thermostatic valve core 9 under the guidance of the channel. The hot and cold water mix in the thermostatic valve core 9, and the mixed thermostatic water flows through the thermostatic channel 16 of the inner shell 7 into the water distribution valve core 3. The mixing ratio of hot and cold water in the thermostatic valve core 9 can be adjusted by rotating the thermostatic handwheel 12. For example, the limit ring 11 restricts the adjustment stroke of the thermostatic valve core 9 to prevent the water temperature from being too high. After the mixed water enters the water distribution valve core 3, the water distribution handwheel 1 is rotated to drive the water distribution valve core 3 to switch the flow channel through the clamping nut 12, so that the mixed water flows into the water outlet channel 18 or water outlet channel 29 of the inner shell 7, and is finally output through the water outlet connector 13 or water outlet connector 24. This not only prevents the risk of scalding caused by the heat conduction of hot water through the outer shell 5 during use, thus improving the anti-scalding function, but also reduces the manufacturing difficulty of the inner shell 7 by adding process holes 17. This thermostatic shower faucet not only prevents scalding caused by hot water conduction through the outer shell 5 during use, thus enhancing the anti-scalding function, but also reduces the manufacturing difficulty of the inner shell 7 by adding process holes 17. Furthermore, it reduces energy consumption and carbon emissions, protects the environment, and uses lead-free environmentally friendly engineering plastic for the thermostatic valve core 9, avoiding contact between water and lead-containing metal materials and reducing the risk of heavy metal leaching, making the product healthier and more environmentally friendly during use.
