Description

Pump for oxygen generator {PUMP FOR OXYGEN GENERATING APPARATUS}

The present invention relates to a pump for an oxygen generator which improves the lay-out of the suction port and the discharge port by changing the position of the pumping part with respect to the motor.

Conventionally, as a pump for an oxygen generator which improves the lay-out of a suction port and an discharge port, what was disclosed by the publication of the utility model registration No. 311886 for which the applicant applied for and registered is proposed, for example.

Figure 6 is an exploded perspective view showing an oxygen generating device applied and registered by the present applicant. As shown in FIG. 6, the pump for the oxygen generator includes a pumping part 100 including a casing 110, an upper valve seat 140, a lower valve seat 150, and a mounting bracket 200; Rotating body 177 having a rotating shaft 810 coupled to the center thereof, a pin 176 eccentrically installed at the center of the rotating body 177 so as to pump the pumping part 100, and the pin 179 can rotate freely. A cam driving unit 170 including a lifting unit 175 for installing a bearing 176 to elevate the piston 173; And a motor 700 which rotates the rotation shaft 810 to transmit rotational power to the cam driver 170. And a gas separation membrane module 300 connected to the pumping unit 100 (for details, refer to the publication).

Through this configuration, when the casing 110 is rotated 180 degrees, the two ports 110a and 110b change their positions to improve the layout of the pumping part 100.

However, the pumping part 100 is fastened and fixed to the female screw parts 810a, 810b and 820a and 820b in which the support brackets 210 and 220 of the mounting bracket 200 are installed in parallel to the front motor support bracket 800. Will be. That is, each of the through support portions 210a and 210b of the support bracket 210 is provided to the female screw portions 810a and 810b, and each of the through support portions 220a and 220b of the support bracket 220 is the female screw portions 820a and 820b. It is disposed in and fastened by a screw (not shown).

Accordingly, the female screw parts 810a and 810b 820a and 820b have a fixed structure in which the front motor support brackets 800 are installed in parallel, so that the lei of the ports 110a and 110b of the pumping part 100 is fixed. It can be constrained by out-of-limits, limiting the design of spaces such as cars.

On the other hand, the cooling of the motor 700 has a structure in which air is sucked and discharged to the outside by a suction fan installed inside or outside the rear motor support bracket 900. However, the release of hot air can only be slowed by the front motor support bracket 800. Therefore, such an air exhaust structure can not only significantly reduce the cooling efficiency of the motor, it is not possible to add a separate component for the cooling of the motor or to continuously run.

In addition, the heat inside the motor 700 in which the cooling efficiency is lowered may be transferred to the pumping part 100, and thus, the oxygen separation efficiency may be lowered, as described in the disclosure filed by the present applicant.

The present invention has been devised to solve the above-mentioned problems, and by simply arranging the suction port and the discharge port at a desired position to improve the layout of the pump, oxygen generation is easy to implement a design such as space utilization and compactness. It is an object to provide a pump for a device.
