Problems solved by technology
[0002] As shown in U.S. Patent No. 5,988,165, it is an oxygen filling device, which mainly uses a motor to drive a crank shaft through a belt, and adopts a three-stage supercharging method to achieve the purpose of boosting the oxygen to 2000PSIG, but its The source of oxygen is the high-pressure oxygen output by the oxygen concentrator, not the low-pressure oxygen source used in ordinary households, so there are considerable restrictions on its use
In addition, using the belt pulley to drive the crank shaft will have problems such as low power efficiency, short service life, low filling efficiency, and poor space utilization efficiency. Secondly, this type of oxygen filling device must be closely integrated with the oxygen generator and cannot operate independently Or compatible with other types of oxygen generators, the flexibility and practicability are insufficient. Secondly, the existing pneumatic cylinder is a fixed structure, so a piston needs to be added to offset the lateral force, so the structure is more complicated. At the same time The stroke of the cylinder is also limited

The invention relates to a family oxygen filling device, which comprises a driving device with a driving axle that mounted with several eccentric driving wheels, while each driving wheel in different eccentric positions relative to the driving axle; rotational wheels sheathing the edge of each driving wheel which can rotate relative to the driving wheel; and several compress cylinders which are axially connected a base. wherein, each compress cylinder comprises a cylinder room and a piston rod axially arranged on the rotational wheel; another end of piston rod is inserted into the cylinder room to form a pressurize room; the pressurize rooms of each compress cylinder are connected via a connecting tube. The invention can effectively improve the operation power and the filling efficiency.
Description
technical field [0001] The present invention mainly relates to an oxygen filling device for household use, especially an oxygen filling device which is convenient for users to store oxygen in an oxygen tank for convenient storage and carrying. Background technique [0002] As shown in U.S. Patent No. 5,988,165, it is an oxygen filling device, which mainly uses a motor to drive a crank shaft through a belt, and adopts a three-stage supercharging method to achieve the purpose of boosting the oxygen to 2000PSIG, but its The source of oxygen is the high-pressure oxygen output by the oxygen generator, not the low-pressure oxygen source used in ordinary households, so there are quite a lot of restrictions on its use. In addition, using the belt pulley to drive the crank shaft will have problems such as low power efficiency, short service life, low filling efficiency, and poor space utilization efficiency. Secondly, this type of oxygen filling device must be closely integrated with...
