2. Whether the infrared sensing part is connected with the waterproof plug by epoxy resin sealing or moisture-proof treatment, the circuit is controlled by a low-power single chip microcomputer, which has anti-interference ability to light and will not be misoperated; The sensing distance can be adjusted by the remote controller, and manual adjustment can easily damp the circuit board, shorten the sensing distance and affect the normal use; The technology of automatic distance adjustment is immature, which will shorten the distance because of color change. The remote control makes the product more user-friendly.
3. The solenoid valve has good waterproof performance. Because it is installed under the basin for a long time, the machine will cause poor contact after being wetted, which will make the machine unable to work. The minimum service life of solenoid valve should reach the industry implementation standard (654.38+0.5 million times or more).
4. Try to choose qualified professional induction faucet manufacturers. Because more than 90% of the induction faucets in domestic professional sanitary ware factories are outsourced, the quality, after-sales and price are not satisfactory; Domestic induction faucet industry lacks brands and leading brands. Many customers take bathroom and bathroom-related brands as reference standards when choosing, mainly recognizing bathroom brands, pursuing unity in brand selection, and often lacking product accessories and professional services in later maintenance.
Don't trust too many promises and guarantees in after-sales service ability. In order to expand sales and attract customers' attention at low prices, some manufacturers and businesses promise a five-year free warranty. This enterprise has developed for less than two years. When there is a real product quality problem or the product is over-guaranteed, they charge the maintenance fee to the customer and fail to implement the three guarantees policy related to the product.
The consumer rights of many users are not guaranteed.
