Abstract: The present disclosure relates to the technical field of blood pressure measurement. Disclosed is a method and an apparatus of non-contact blood pressure measurement based on radar technology. The method includes: performing a signal detection operation on a target body part of a user to be measured by means of a radar detector to acquire a signal parameter of an echo signal of the user to be measured; identifying, according to the signal parameter of the echo signal, biological signal information of the user to be measured; and performing a blood pressure prediction operation, according to the biological signal information, on the user to be measured to acquire a blood pressure parameter of the user to be measured.

Abstract: A water purifier is provided, including a main housing, a waterway board component and a bracket component, the waterway board component and the bracket component are connected to form an electric-water total assembly module and are connected to the main housing. One side of the waterway board component is provided with a filter element plugging structure. A first end of the bracket component is connected to the waterway board component, the waterway board component is in “L” shaped connection with the bracket component; and the bracket component is arranged close to one side of the waterway board component. Or, the waterway board component is in “T” shaped connection with the bracket component; and the bracket component is arranged close to a middle part of one side of the waterway board component. The water purifier has a compact structure, is convenient to assemble, and has low cost.

Abstract: A water purifier is provided, including a main housing, a waterway board component, and a bracket component. A mounting opening is provided on one surface of the main housing, the waterway board component and the bracket component are inserted into the main housing from the mounting opening. At least two first and second reinforcing ribs are respectively arranged on the opposite first side wall and second side wall of the main housing. Both the first reinforcing ribs and the second reinforcing ribs extends into the main housing along the mounting opening. First limiting slots and second limiting slots are provided in two sides of the waterway board component or/and the bracket component, the first limiting slots are clamped to the first reinforcing ribs, and the second limiting slots are clamped to the second reinforcing ribs. The present disclosure has high structural stability, and provides a good user experience.
