TECHNICAL FIELD
[0001] The application relates to the technical field of bathtubs, in particular to a composite Corian bathtub. BACKGROUND
[0002] Corian is the world's first solid panel material invented by the American DuPont Company, and its main components are methyl methacrylate, alumina trihydrate and pigments. The composite Corian bathtub is a new type of bathtub material developed on this basis, which has many advantages such as high density, no dirt accumulation, heat resistance, not easy to crack, easy to repair, etc. Its surface is usually made of white matte, which feels like skin when touched. These characteristics make the composite Corian bathtub more comfortable, beautiful and durable in use, and can meet people's demand for high-quality bathroom products.
[0003] The existing patent (publication number: CN221430916U) discloses the application relates to the technical field of bathtubs, in particular to a Corian composite bathtub, which comprises a bathtub body, a water inlet is arranged on the inner wall of the bathtub body, a drain is arranged on the inner bottom wall of the bathtub body, a main control unit is arranged on the outer surface of the bathtub body, a buzzer alarm is fixedly installed on the outer surface of the bathtub body, and a liquid level sensor is fixedly installed on the inner wall of the bathtub body. The Corian composite bathtub is provided with a bathtub inner layer, a reinforcing layer, an intermediate filling layer, a heat preservation layer, a heat insulation layer and a bathtub outer layer. The bathtub inner layer is made of Corian material, which has excellent impact resistance and heat resistance, thereby improving the impact resistance and heat resistance of the bathtub. In combination with the heat preservation layer and the heat insulation layer, the resin perlite insulation board material has good heat preservation performance, which can reduce the heat loss in water and prevent the hot water in the bathtub from cooling down quickly due to excessive heat dissipation of the bathtub itself.
[0004] In the above-mentioned comparative document, although the Corian composite bathtub adopts a multi-layer structure design including a bathtub inner layer, a reinforcing layer, an intermediate filling layer, a heat preservation layer, a heat insulation layer and a bathtub outer layer, it can still lack a constant temperature maintaining function. For users who pursue long-term constant temperature bathing enjoyment, this defect may affect the user's purchase decision and overall satisfaction, and the introduction of the multi-layer structure increases the production complexity and maintenance difficulty of the bathtub. Practical new type content

This design not only improves the heat preservation performance of the bathtub, but also simplifies the structure, reduces the production complexity and subsequent maintenance cost of the bathtub, realizes the dual optimization of practicality and economy, and provides additional support and stability for users during use of the bathtub, ensuring the safety of users during use.
[0008] Further, the upper surface of the bathtub outer layer is fixedly connected with a limiting ring, and the inner wall of the limiting ring is fixedly connected with the outer surface of the bathtub faucet.
[0009] Through the above scheme, by setting the limiting ring, the limiting ring can limit the bathtub faucet, ensuring the stability of the bathtub faucet during long-term use.
[0010] Further, the upper surface of the bathtub outer layer is fixedly connected with two groups of fixed plates, and the inner walls of the two groups of fixed plates are respectively fixedly connected with the two ends of the two handrails.
[0011] Through the above scheme, by setting the fixed plate, the fixed plate can fix the handrail, ensuring that the handrail is still stable and reliable after long-term use.
[0012] Further, the upper surface of the bathtub outer layer is fixedly connected with a protective frame, and the inner wall of the protective frame is fixedly connected with the outer surface of the control panel.

[0014] Further, the inner bottom wall of the bathtub inner layer is fixedly connected with an anti-skid pad.
[0015] Through the above scheme, by setting the anti-skid pad, the user can be effectively prevented from slipping in the bathtub, and the safety of the user in the bathtub is improved.
[0016] Further, the outer surface of the drain plug is fixedly connected with a sealing ring.
[0017] Through the above scheme, by setting the sealing ring, the sealing effect of the drain plug can be achieved, the sealing property of the drain port when closed is ensured, and the sealing ring also has a certain elasticity, which can provide buffering and reduce wear and tear when the drain plug is inserted and pulled out.
[0018] Further, the bottom surface of the bathtub outer layer is fixedly connected with a limiting plate, and the inner wall of the limiting plate is fixedly connected with the outer surface of the drain pipe.
[0019] Through the above scheme, by setting the limiting plate, the limiting effect of the drain pipe can be achieved, the stability of the drain pipe during use is enhanced, and it is ensured that the drain pipe will not shake or fall off during use.
[0020] Further, the inner wall of the bathtub inner layer is fixedly connected with a fixing frame, and the inner wall of the fixing frame is fixedly connected with the outer surface of the liquid level sensor.

During use of the user, these components can monitor the water temperature and liquid level change in the bathtub in real time, and accurately feedback the data to the control panel in real time. The control panel quickly reacts according to the received signal, automatically adjusts the water temperature and flow rate of the bathtub faucet, so that the water temperature in the bathtub is always maintained within the ideal range preset by the user. By setting the heat preservation layer, the heat loss is effectively blocked, and the duration of hot water bath is prolonged. This design not only improves the heat preservation performance of the bathtub, but also simplifies the structure, reduces the production complexity and subsequent maintenance cost of the bathtub, realizes the dual optimization of practicality and economy, and provides additional support and stability for the user during use of the bathtub, ensuring the safety of the user during use.
