Abstract: The present disclosure provides a rotation type electric toothbrush. The electric toothbrush includes a brush handle module, a vibration module and a brush head module having a brush base, a brush cover and bristles. The brush cover and the brush base are in a detachable connection. The bristles are disposed on the brush base. The brush base includes a groove. The vibration module includes a motor and an eccentric shaft having a transmission connection with the motor. The eccentric shaft inserts into the groove. When the rotation type electric toothbrush is working, the eccentric shaft rotates eccentrically to contact a side surface of the groove, so as to drive the brush base and the brush cover to have a reciprocating rotation synchronously.

Abstract: Systems and methods are provided for cross-terminal pushing of applications. For example, installation information of an application corresponding to an application-push event in a browser opened in a first terminal is acquired upon detection of the application-push event being triggered; the first terminal sends a push instruction to a server, the push instruction carrying the installation information of the application; the server sends the installation information of the application to one or more second terminals related to the first terminal; the second terminals send the installation information of the application; and the second terminals install the application based on at least information associated with the installation information of the application.

Abstract: The present invention discloses a method and apparatus for obtaining dynamic information. In the method, a first client of a first user obtains a relationship chain of the first user, wherein the relationship chain of the first user comprises at least one second user; determines an active degree of the at least one second user in a preset first time period, determines a time interval reference value of requesting dynamic information according to the active degree, determines an information updating degree of the at least one second user in a preset second time interval, determining a time interval adjustment value of requesting the dynamic information based on the information updating degree; determines a time interval value according to the time interval reference value and the time interval adjustment value of requesting the dynamic information, and requests the dynamic information of the at least one second user according to the time interval value of requesting the dynamic information.
