Abstract: A pressure-compensation controlled hydraulic pump, comprising an electric proportional pressure compensator, a hydraulic pump, a hydraulic control reversing valve and a servo cylinder; the electric proportional pressure compensator can be electrically connected to a controller, a first hydraulic control port of the hydraulic control reversing valve is connected to an internal oil drain path, and is connected to an internal output oil path by means of a hydraulic control oil inlet path provided with a first throttle valve, a second hydraulic control port is connected to the internal output oil path, and the pressure difference between an opening pressure of the electric proportional pressure compensator and an oil outlet pressure of the hydraulic pump can drive the hydraulic control reversing valve to perform reversing, and selectively enable a piston chamber of the servo cylinder to be in communication with the internal output oil path or the internal oil drain path.

Abstract: The present invention relates to a cigarette smoking device having an electronic atomization function, including a cigarette holder and an electronic atomization component cooperatively assembled with one another, wherein the cigarette holder includes a cigarette holding cavity and an optional end cap for closing the open end of a shell; the electronic atomization component includes the shell and the following components located in the shell: a power supply, an airflow sensor switch and an atomizer provided with a central airflow channel; the cigarette holding cavity is in air communication with the central airflow channel of the atomizer; the cigarette smoking device further includes an airflow sensor switch air inlet penetrating the shell and/or the end cap of the cigarette holder. Also provided is a method for improving cigarette smoking quality, the method includes smoking after mainstream smoke generated by an end-lighting cigarette, dilution air and atomization vapor are mixed.
