2results about How to "Save quantity" patented technology

The utility model discloses a neck massager, including casing, drive motor, first transmission shaft, transmission belt, second transmission shaft, knead mechanism and knock mechanism, drive motor is installed in the casing, and first transmission shaft transmission is connected in drive motor, and transmission belt transmission is connected in first transmission shaft, and second transmission shaft transmission is connected in transmission belt, and knead mechanism transmission is connected in first transmission shaft, and knock mechanism transmission is connected in second transmission shaft. Through the transmission cooperation of a drive motor in the same casing through first transmission shaft, transmission belt, second transmission shaft, can distribute power to knead mechanism and knock mechanism simultaneously, only one motor can be in the same time output knead and knock two different movement forms, save motor quantity and internal space, two kinds of massage action are driven by the same power source, and frequency, phase is natural consistent, thoroughly eliminates the massage idle gear of traditional time-sharing switching, guarantees the continuity and superposition effect of compound technique.

The utility model belongs to the technical field of pressure swing adsorption equipment, and aims to provide energy-saving pressure swing adsorption gas production equipment which comprises a gas supply unit, an adsorption unit and a gas storage unit which are sequentially connected, the gas supply unit comprises a process air buffer tank, and a clean compressed air inlet is formed in the front end of the process air buffer tank; the adsorption unit comprises a plurality of pressure swing adsorption gas making machines; the gas storage unit comprises a process pure gas buffer tank, the side face of the upper end of the process pure gas buffer tank is connected with the main gas outlet pipeline, the side face of the lower end of the process pure gas buffer tank is provided with a finished gas pipeline, and the tail end of the finished gas pipeline is provided with a finished gas outlet and an unqualified gas discharge outlet. The energy-saving pressure swing adsorption gas production equipment disclosed by the utility model has the characteristics of compact structure, obvious energy-saving effect, high utilization rate of clean compressed gas, low equipment cost, small occupied area and the like, and can be widely applied to the technical field of production of the pressure swing adsorption gas production equipment.
