Spot checks found that 11 batches of product grounding measures failed the project, and may have potential risk of electric shock during use; 2 batches of heat-resistant and flame-resistant projects were unqualified, and non-flame-retardant materials or materials with poor flame retardance were used, and there was a fire. Risks: 1 batch of product input power and current items are unqualified, and the input power detection value of the product is lower than the indicated value. When it is used, it will cause some functions (such as cleaning, massage, heating, drying, etc.) to fail to operate normally; 1 The power connection and external cord items of the batch product were not qualified. The cross-sectional area of the product's nominal power cord was ≥1.0mm2, and the actual measurement was only 0.75mm2. There were 12 batches of products that did not meet the standard requirements in the product or user manual. Mark the prescribed signs, instructions and warnings.
