Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to a novel anti-scalding constant temperature plastic waterway. Background Technology

[0002] With the development of the bathroom industry, thermostatic water pipes, as core components of showers, bathtubs, and other sanitary ware, have become a key focus for users in terms of their anti-scalding performance, installation flexibility, and flow rate adaptability. Currently, thermostatic water pipes on the market are mainly divided into two structural forms: one is a split structure with a plastic body, where the water passages need to pass through the inside of the outer shell. Due to the limitations of water passage sealing and temperature resistance requirements, the outer shell can only be made of metal materials such as stainless steel or pure copper, which not only increases product costs but also limits the diversity of outer shell material choices; the other is a one-piece structure with a plastic body, where all water passages flow through the inside of the plastic body. Although it has a certain anti-scalding effect, it has obvious design flaws.

[0003] Existing integrated plastic thermostatic water channels only allow the thermostatic valve core to be installed on the right side, failing to meet the needs of some users who prefer left-side installation. Furthermore, their excessively long hot water flow channel results in poor scalding protection, increasing the risk of burns. Additionally, the current integrated design typically offers only a 13-15L water flow rate, suitable only for showers and unable to meet the high-flow demands of bathtubs, thus limiting its applicability. Moreover, the valve cores in existing products have poor compatibility, making them difficult to integrate with thermostatic valve cores from different brands, further restricting the product's market applicability.

[0004] Given the shortcomings of the existing technologies, there is an urgent need for a thermostatic plastic waterway that can achieve left-side constant temperature installation, is compatible with various shell materials, has a large flow output, and has excellent anti-scalding effect, in order to resolve the contradiction between current market demand and product performance. Utility Model Content

[0005] The purpose of this invention is to provide a novel anti-scalding, temperature-controlled plastic water channel to solve the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides the following solution: This utility model provides a novel anti-scalding, temperature-controlled plastic water channel, comprising: The plastic water channel body has an inlet channel extending along its internal length. Hot water inlet holes and cold water inlet holes are located on the sides of the plastic water channel body, respectively connected to both ends of the inlet channel. A valve mounting groove is located at the left end of the plastic water channel body, connected to the hot water inlet hole. An inlet flow channel is provided between the valve mounting groove and the other end of the plastic water channel body. Two sets of mixing water distribution channels are located at the other end of the plastic water channel body. Two sets of mixing water outlets are located on the sides of the plastic water channel body, respectively connected to the mixing water distribution channels. A thermostatic valve core is installed in the valve body mounting groove. A thermostatic sleeve is fitted over the thermostatic valve core. A hot water inlet is provided on the side of the thermostatic sleeve and is connected to the water inlet channel. A cold water hole and a mixing water hole are provided at the bottom of the thermostatic sleeve and are connected to the water inlet channel and the mixing water distribution channel, respectively. A sealing element is provided on the hot water inlet. The main body of the plastic waterway is installed inside the outer casing.

[0007] According to the novel anti-scalding and constant temperature plastic water channel provided by this utility model, the sealing element includes a shaped silicone sealing ring, which is installed on the hot water inlet.

[0008] According to the novel anti-scalding and constant temperature plastic water channel provided by this utility model, the bottom of the valve body mounting groove is set as an inclined surface.

[0009] According to the new anti-scalding and constant temperature plastic water channel provided by this utility model, the main body of the plastic water channel is a one-piece molded plastic water channel.

[0010] According to the novel anti-scalding thermostatic plastic water channel provided by this utility model, a sealing ring is provided between the thermostatic valve core and the thermostatic sleeve.

[0011] According to the new anti-scalding constant temperature plastic water channel provided by this utility model, the bottom of the constant temperature sleeve is equipped with a water-proof O-ring.

[0012] The present invention discloses the following technical effects: By adding a special left-side thermostatic irregular-shaped sleeve composed of plastic and silicone, the limitation of the existing one-piece plastic body that can only install thermostatic valve cores on the right is broken, meeting the left-side thermostatic needs of different customers; the irregular-shaped sleeve shortens the hot water flow channel, reducing the risk of heat conduction to the outer shell, and the anti-scalding effect is significant; and the installation can be completed simply by positioning the upper and lower connectors, which is simple to operate and reduces construction costs and time.

Detailed Implementation

[0016] 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.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Reference Figures 1-8This utility model provides a novel anti-scalding, temperature-controlled plastic waterway, comprising: The plastic water channel body 1 has an inlet channel 2 extending inside it. Hot water inlet hole 3 and cold water inlet hole 4 are provided on the side of the plastic water channel body 1. The hot water inlet hole 3 and cold water inlet hole 4 are respectively connected to the two ends of the inlet channel 2. A valve body mounting groove 5 is provided at the left end of the plastic water channel body 1. The valve body mounting groove 5 is connected to the hot water inlet hole 3. An inlet flow channel 6 is provided between the valve body mounting groove 5 and the other end of the plastic water channel body 1. Two sets of mixed water diversion channels 7 are provided at the other end of the plastic water channel body 1. Two sets of mixed water outlets 8 are provided on the side of the plastic water channel body 1. The mixed water outlets 8 are respectively connected to the mixed water diversion channels 7. Thermostatic valve core 9 is installed in valve body mounting groove 5. Thermostatic valve core 9 is covered with thermostatic sleeve 10. Hot water inlet 11 is opened on the side of thermostatic sleeve 10. Hot water inlet 11 is connected to water inlet channel 2. Cold water hole and mixing water hole are opened at the bottom of thermostatic sleeve 10. Cold water hole and mixing water hole are connected to water inlet channel 2 and mixing water watering channel 7, respectively. A sealing element is provided on hot water inlet 11. The plastic waterway body 1 is installed inside the outer shell.

[0019] Cold water enters the main body 1 through the cold water inlet 4 on the side and hot water enters the main body through the hot water inlet 3, respectively, into the internal water inlet channel 2. Both flow along the water inlet channel 2 towards the valve body mounting groove 5 on the left. The thermostatic valve core 9 inside the valve body mounting groove 5 is covered by a special left-side thermostatic sleeve 10. The hot water inlet 11 on the side of the sleeve, along with a sealing element, achieves a water circuit seal. Cold water enters the valve core cavity through the cold water hole at the bottom of the thermostatic sleeve 10, where it mixes thoroughly with the hot water whose temperature has been adjusted by the thermostatic valve core 9. The mixed water flows along the water inlet channel 6 between the valve body mounting groove 5 and the other end of the main body, into two sets of parallel mixed water separation channels 7, and finally is stably output from two sets of mixed water outlets 8 on the side of the main body. Throughout the process, the one-piece molded plastic body ensures that all water flows only internally and does not come into contact with the outer shell. Combined with the shortened hot water flow channel of the irregularly shaped thermostatic sleeve, heat loss is effectively reduced. At the same time, the large flow channel design with side inlet and bottom outlet ensures that the water flow rate is stable at over 21L, making it suitable for shower and bathtub scenarios. Furthermore, the installation method with upper and lower connector positioning does not require complicated adjustments, simplifying the assembly process.

[0020] The design was further optimized, and the sealing component includes a shaped silicone sealing ring 12, which is installed on the hot water inlet 11.

[0021] The design was further optimized by setting the bottom of the valve body mounting groove 5 as a slope.

[0022] Further optimization of the design resulted in the main body of the plastic waterway being a one-piece molded plastic waterway.

[0023] The design has been further optimized by installing a sealing ring between the thermostatic valve core 9 and the thermostatic sleeve 10.

[0024] The design has been further optimized by installing a water-proof O-ring at the bottom of the thermostatic jacket 10.
