Oxygen therapy patients can be mainly classified as non-mobile and mobile. Eighty percent of patients require 1.5 to 2.0 liters of oxygen per minute, 15 hours a day. Mobile patients may need both portable and fixed oxygen devices in their lives. While the patient is exercising, the oxygen flow demand may increase to 4 to 6 liters per minute. Oxygen concentrators separate oxygen from the air, and the key components are: medical grade compressors need to develop advanced technology and innovative electromechanical structure design to meet the needs of mobile patients. A single-chamber cylinder compressor is disclosed in the first embodiment of the present invention. As shown in the first figure, the design of the armature and the piston is the stator and the electromagnet winding is the stator. When the electromagnet winding is connected to the voltage of the parent, the electromagnet winding intermittently generates a magnetic force to attract the armature, and does not move, thereby driving the piston connected to the rear end of the armature to push forward, and shrinking the front end of the armature a spring; when the magnetic force disappears, the spring reverts and pushes the armature and the piston back. This compressor design uses the aforementioned electromagnetic force f spring restoring force as the driving force of the mover, and the generated thrust is small. Furthermore, the compressor requires a longer length, making it larger. In addition, this type of compressor uses a single-chamber fixed-volume cylinder.

The permanent magnet type linear brushless pump 1 is described below as an air compressor to explain its operation mechanism. Referring to FIG. 3A and FIG. 4A, when the current does not pass into the pair of fixed electromagnet winding groups 14a and i4b of the permanent magnet linear brushless pump, the pair of fixed electromagnet windings The lateral branches of the groups 14a and 14b do not generate a magnetic field, and each pair of adjacent opposing magnetic fields of the permanent magnet arrays 24 & and 124b of the movable cylinder 12 attracts the pair of stationary electromagnets. One of the lateral branches corresponding to the winding sets Ma and 14b maintains the movable cylinder 12 in the center equilibrium position. In this case, the internal air pressure of the first cylinder chamber 120a and the second cylinder chamber 120b are balanced with the outside atmospheric source. Referring to FIG. 3B and FIG. 4B, when the alternating current phase of the pair of fixed electromagnet winding groups 14a and 14b is positive, the pair of stationary electromagnets 200925420 are wound on the sides of the groups 14a and Hb. An alternating positive and negative magnetic field is generated to the branch to attract the corresponding magnets of the pair of permanent magnet arrays 124a and 124b, thereby causing the movable cylinder 12 to be pushed forward to the side to cause the second cylinder chamber 120b to be Compressed' and the first cylinder chamber 120a expands. In this case, the high pressure air is generated inside the second cylinder chamber 120b, and flows to the sub air chamber 164b through the one-way valve 168b, and then is sent to the connected oxygen concentrator via the passage hole 182b (refer to the first figure). High pressure gas receiving line. The air pressure inside the first cylinder chamber 120a is lowered, so that the external air flows into the first cylinder chamber 120a via the passage hole 180a (refer to the first figure), the auxiliary air chamber 162a, and the check valve 166a. . Further, after the sub air chamber 164b of the fixed piston seat 16b is introduced into the high pressure air from the second cylinder chamber 120b, the sub air chamber 16 is expanded outward, so that the fixed piston seat 16b and the movable portion The engagement between the cylinders 12 is more compact. Referring to the third C diagram and the fourth C diagram 'when the alternating current phase of the pair of fixed electromagnet winding groups 14a and 14b is negative, the adjacent pairs of the fixed electromagnet winding groups 14a and 14b The alternating positive and negative magnetic fields generated by the lateral branches are reversed, and the movable cylinder 12 is pushed rearward to the other side, causing the first primary cylinder chamber 120a to be compressed' and the second secondary cylinder chamber 120b to expand. In this case, 'the first cylinder chamber 12〇a generates high-pressure air inside, and flows through the one-way valve 168a to the sub-air chamber 164a' and then feeds the connected oxygen via the passage hole 182a (refer to the first figure). The high pressure gas receiving line of the concentrator. The internal air pressure of the second cylinder chamber 120b is lowered, so that the outside air flows into the second cylinder chamber 120b via the passage hole 180b (refer to the first figure), the sub air chamber 162b, and the check valve 166b. Moreover, after the sub air chamber 164a of the fixed piston seat 16a is introduced into the high pressure air from the first cylinder chamber 120a, the sub air chamber 164a expands outward, so that the fixed piston seat 16a and the movable type The engagement between the cylinders 12 is more compact. 12 200925420 The partition m in the movable cylinder u is detachable, and the movable cylinder 12 can be adjusted by replacing the partition 122' of different thickness; the air compression ratio (ie, the first cylinder chamber) The ratio of the maximum volume after expansion of the 12〇a or second steam red chamber 120b to the minimum volume after compression is further adjusted to further adjust the pressure and flow performance of the compressed air. Furthermore, the permanent magnet linear brushless of the present invention The pump i can expand the PWM frequency frequency controller and the ^ know g road to precisely control the high pressure air pressure and its flow rate.
