According to media reports, Mr. Jin from Fangcun, Guangzhou, took his family on a trip when he suddenly received a phone call from the property, saying that black smoke was coming out of his home, emitting a smell of burnt wires. < / P > < p > after obtaining Mr. Jin’s consent, the property quickly entered Mr. Jin’s home and found that the culprit was the intelligent toilet lid of the toilet, which caused “tragedy” due to spontaneous combustion. < p > < p > after Mr. Jin went home, not only was the smell of scorching for a long time, but the furniture and countertops were not covered with a thick layer of soot. According to the preliminary assessment, the loss was nearly 100000 yuan, which was basically the rhythm of redecoration. < / P > < p > so the question is, why should the intelligent toilet cover use fireproof materials? Although the traditional toilet cover hand in hand with smart home, add a lot of humanized functions, such as automatic flushing with warm water after defecation, the jet water can also move back and forth to achieve the effect of water mill. < / P > < p > not to mention whether you can be used to it, but as for the function of heating, there is the possibility of fire caused by electric leakage, so the use of fireproof materials is the top priority. < p > < p > fire retardant materials can be divided into “strong” and “weak” ones. Generally, the flame retardant grades of plastics are divided into different grades: from Hb, V-2, V-1 to V-0, and V-0 is the highest standard, which means that after twice 10 second combustion tests, the flame will be extinguished within 30 seconds and no combustibles can be dropped. < / P > < p > fire resistant materials are the last line of defense after a fire, and we should pay more attention to how manufacturers of smart toilet covers can strangle the danger in the cradle – mainly depending on the waterproof grade. < / P > < p > the humid environment in the toilet provides natural conditions for the “leakage” behavior. Even if the separation of dry and wet in the toilet is achieved, it is still unable to stop the invasion of the water source in the sink or even the toilet to the circuit, so the waterproof measures and waterproof grade are particularly important. < / P > < p > the waterproof grade is divided into nine grades from 0 to 8. The higher the level, the better the waterproof effect. The intelligent toilet cover must reach the IPx4 level at least, in order to prevent the water splashing from all directions to invade the electrical appliances and cause damage. < / P > < p > in addition, it should be reminded that even if the waterproof level reaches IPx4, the shower head should not be used to directly spray the toilet cover in daily use, and it is recommended to use the wiping method for cleaning and disinfection. < / P > < p > there is no airtight wall and no electric appliances that do not leak electricity. Only by combining two measures can we make the intelligent life experience safer. Relatively speaking, some famous brands are relatively reliable and professional in leakage protection measures. < / P > < p > for ordinary consumers, when searching and evaluating on the Internet, they can see some dismantling contents. Generally, the intelligent toilet cover processed by glue filling process can better and comprehensively protect the circuit board and avoid the invasion of water. < / P > < p > it is also very important to support the grounding of the intelligent toilet cover. If the electrical insulation of the intelligent toilet cover is damaged in case of accident, it is necessary to rely on the grounding measures to flow the leakage current to the ground, so as to avoid injury to users and cause electric shock hazard. < p > < p > at the same time, the happiness function of the intelligent toilet cover, PP water jet massage gun, is a nest of bacteria and viruses. < / P > < p > therefore, in terms of health and safety, careful evaluation should be made when purchasing. The self-cleaning function of the nozzle can wash and remove the urine and other stains stuck in the use, and prolong the breeding cycle of bacteria. < / P > < p > in terms of water spray heating function, it is recommended that you choose the instant hot type intelligent toilet cover. Although it is a little expensive, it can effectively avoid the risk of bacteria breeding in the water tank of the heat storage toilet cover while saving energy and electricity. However, for China’s domestic market, it is still an emerging product. The threshold for enterprises to enter the industry is relatively low. At present, there is also a lack of professional compulsory certification (CCC). The technology research and development and quality level of different brands are uneven. Therefore, when purchasing, do not save “safety” money just for the sake of convenience.
