  • ORAL CLEANING DEVICE
    Publication number: 20260033934
    Abstract: A brush head includes a shell and bristles mounted on a side of the shell. The shell includes a first airflow channel and a liquid guiding channel. The first airflow channel includes an air outlet hole facing the side of the shell on which the bristles are arranged and the liquid guiding channel includes a liquid outlet port located at the side of the shell on which the bristles are arranged such that the air output from the first airflow channel and the liquid output from the liquid guiding channel can be mixed at the area around the liquid outlet port to form abundant bubbles.

  • Method for synthesizing diaza-bridged compound and a diaza-bridged compound
    Patent number: 11649244
    Abstract: The present disclosure discloses a method for synthesizing a diaza-bridged compound and a diaza-bridged compound, belonging to the field of organic synthesis. The present disclosure includes the following reaction: in the formula, R is aryl, substituted aryl, alkyl or haloalkyl, Ra is any one of H, 2-nitrobenzenesulfonyl, 4-nitrobenzenesulfonyl or 2,4-dinitrobenzenesulfonyl, n=1 or 2. Since compound 2 and NH3 are used as raw materials, the present disclosure can not only effectively shorten the process flow and save process costs, but also improve the reaction yield to a certain extent. The present disclosure also provides a diaza-bridged compound, where the structural formula thereof is in the formula, Ra is any one of 2-nitrobenzenesulfonyl, 4-nitrobenzenesulfonyl or 2,4-dinitrobenzenesulfonyl.
