With continuous innovation of intelligent closestool products, the intelligent development of the products is continuously upgraded, and the product quality is also improved to a new level.
The toilet bowl and the intelligent toilet bowl mainly comprise a main body, a seat ring and a cover plate, wherein the main body is mainly made of ceramic materials, and with the development of the technology, the existing parts are made of materials such as artificial marble, glass fiber reinforced plastic and the like; and for the seat ring and the cover plate part, the materials are very many, including PP, acrylic materials, PVC materials and the like, and different materials show different performances. The intelligent toilet bowl is different from a common toilet bowl, and a seat part of the intelligent toilet bowl is provided with a heating wire for heating so as to have the functions of heat preservation and heating; in addition, the toilet bowl has electromechanical system or program control, so that the toilet bowl product can complete the basic functions of hip washing, women washing and the like. However, in any configuration, in the actual use of the toilet seat, the human body load directly contacts the toilet seat and performs different operations such as vertical loading, integral loading (squat toilet), and one-sided side-to-side swinging according to different use characteristics. In recent years, related devices are available in the market in connection with the occurrence of cracks and fractures in the seat of toilet bowls, particularly intelligent toilet bowl products. However, there are several problems:

There is a need for improvements in existing equipment.
In the aspect of a test method, in the force loading direction, the force with a certain inclination is currently used for loading, and the force is inconsistent with the actual use state and cannot meet the actual use condition of a product; in addition, in the aspect of the intelligent toilet bowl, the intelligent toilet bowl has the functions of heating the seat ring and the like, the test results of the intelligent toilet bowl are greatly different under different heating modes, test times, test temperatures and simulation states, and the test method is not specified at home and abroad.
