Description of the invention (1) 1. [Technical field to which the invention belongs] The present invention mainly relates to a piston pump, and more particularly to an electromagnetic rotary piston pump. 2. [Previous technology] A pneumatic pump is a device that uses mechanical principles to reduce gas volume to increase gas pressure. There are generally three types of reciprocating, centrifugal and axial flow. The reciprocating pump can obtain a wider pressure range , So it ’s most commonly used by people. Reciprocating pumps are mainly called reciprocating piston pumps because a piston reciprocates in a certain space to compress the gas to generate pressure. At present, in order to enable the reciprocating piston pump to obtain a large gas pressure, electromagnetic force is usually used to drive the piston, as shown in Figure 1. However, the reciprocating piston pump shown in FIG. 1 has the following problems. First, after the piston compresses and discharges the gas, the piston must return to the initial position to perform the next compression stroke, so the obtained gas pressure will have a problem of pressure discontinuity. Second, in order for the pump to obtain stable and continuous pressure, an additional pressure storage tank is usually required. Third, the intake valve, exhaust valve, and check valve that limit the direction of gas in and out of the double piston pump are composed of many parts, which not only increases the complexity of the system, but also makes it difficult to maintain the system. Fourth, the friction generated during the reciprocating movement of the piston will consume a large amount of kinetic energy of the piston, which must provide more kinetic energy to the piston, resulting in an increase in work costs and a decrease in work efficiency. In view of this, the present invention proposes an electromagnetic rotary piston pump to

For example, the exhaust opening 10b of an electromagnetic rotary piston pump 1 can be connected in series with the intake opening 2a of an electromagnetic rotary piston pump 2. The exhaust opening 2 0 b of the electromagnetic rotary piston pump 2 is connected in series with the intake opening 3 0 a of an electromagnetic rotary piston pump 3, and so on. In this way, we can finally pass the exhaust opening 3 0 b Get higher pressure and higher air volume. As mentioned above, since the piston of the electromagnetic rotary piston pump of the present invention rotates continuously in the inner annular tube, it does not need a check valve to generate and generate continuous pressure, and reaches the same pressure range as the conventional reciprocating pump. In addition, the electromagnetic energy loss of the electromagnetic rotary piston pump of the present invention is only related to the friction of the piston during acceleration, so it can effectively reduce the electromagnetic energy loss and improve the work efficiency. In addition, it should be noted that although this embodiment The outer ring is made of plastic, but the material of the outer ring is not limited to this. Similarly, the material of the inner ring pipe is not limited to brass, but can be other materials with low friction coefficient. In addition, the phase difference between the intake opening and the exhaust opening of the present invention is not limited to 180 degrees, and may be changed according to design requirements. In summary, the present invention has been described in detail through the above-mentioned embodiments and modified examples. However, those skilled in the art should understand that all the embodiments of the present invention are merely illustrative and not restrictive, that is, without departing from the present invention.
