Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cartridge of an oxygen concentrator,

The present invention relates to a cartridge of an oxygen concentration apparatus for producing and supplying a gas having a high oxygen concentration by adsorbing nitrogen in air with an adsorbent.

As such an oxygen concentration apparatus, for example, an apparatus using a pressure swing adsorption (PSA) method has been conventionally known as disclosed in Japanese Unexamined Patent Application Publication No. 2008-148859 (Patent Document 1) have. In the oxygen concentration apparatus using this pressure swing adsorption method, an adsorbent is filled in the adsorption column. Then, air is introduced into the adsorption column, nitrogen of the introduced air is adsorbed by the adsorbent to concentrate the oxygen, and the oxygen-enriched gas is supplied. Since the adsorbent adsorbs a predetermined amount of nitrogen, the adsorption capacity is lowered. Therefore, the pressure in the adsorption column is lowered to release nitrogen adsorbed from the adsorbent to regenerate. In this way, the adsorbent repeatedly adsorbs and releases nitrogen, but deteriorates when the period of use is prolonged. Therefore, it is necessary to replace the deteriorated old adsorbent with a new adsorbent. Since this replacement work is difficult for a person who is not an expert, the oxygen concentrator is sent to a store or a management factory so that the operator exchanges the adsorbent and returns it to the user.

Japanese Patent Application Laid-Open No. 2008-148859

The problem to be solved is that it is necessary to send an oxygen concentrator to a store or a management plant to exchange the adsorbent

A cartridge (3) of an oxygen concentration apparatus of the present invention has a pair of adsorption columns (21) filled with an adsorbent and a flow path switching device (12) for changing the air supply flow path to be introduced into the adsorption columns, The switching device is operated to alternately switch the adsorption column to which the air is supplied and adsorb nitrogen from the air according to the pressure swing adsorption method to concentrate the oxygen and supply the oxygen enriched gas. The cartridge is accommodated in the main body of the oxygen concentrator and accommodates the pair of adsorption cylinders, and the one end of the cartridge is provided with a flow path switching device connection for connecting one end of each adsorption cylinder to the flow path switching device An oxygen concentration gas discharge vent 22a for discharging the oxygen enriched gas from the other end of each adsorption column is provided and the cartridge is mounted on the main body of the oxygen concentrator by pushing the cartridge, The flow path switching port for connecting the flow path switching device and the oxygen concentrator discharging port are connected to the corresponding main body side vent holes 36 and 37 so that the cartridge is detached and the cartridge side vent port is detached from the main vent port .

Further, the other end of each adsorption column may communicate with the oxygen-enriched gas discharge vent through the check valve (28).

The cartridge-side ventilation hole and the main body-side ventilation hole may be coupled to each other with one side protruding and the other side recessed.

At one end of the cartridge, a dilution gas inlet 23a for introducing the dilution gas is provided, and the dilution gas introduced from the dilution gas inlet is mixed with the oxygen-enriched gas in the cartridge.

The cartridge has a handle 61 on which one side of the guide 64 or the engaging part 72 is provided and the other side of the guide part or the engaging part is provided on the body of the oxygen concentrator, When the engaging portion is pushed into the main body of the oxygen concentrator, the engaging portion is engaged with the guiding portion, and when the handle is pivoted in this state, the engaging portion and the guiding portion are engaged with each other.

According to the present invention, at one end of a cartridge for accommodating a pair of adsorption columns, there are provided a flow passage switching device connection port for connecting one end portion of each adsorption container to the flow path switching device and a connection port for connection from the other end of each adsorption column to the oxygen- The cartridge can be installed in the main body of the oxygen concentrator by pushing the cartridge. Therefore, when the adsorbent deteriorates, the cartridge can be removed from the main body of the oxygen concentrator and separated, and a new replacement cartridge can be simply pushed in to perform the replacement operation. As a result, it is not necessary to send the main body of the oxygen concentrator to a store or a management factory for exchanging the adsorbent.

In addition, when the diluting gas introduced from the diluting gas vent is mixed with the oxygen-enriched gas in the cartridge, the one end of the cartridge is provided with the diluting gas vent for introducing the diluting gas, This is simplified.

When the cartridge has a handle and the handle is pivoted so that the cartridge can not be taken out by the engagement of the engaging portion and the guide portion, it is possible to prevent the cartridge from being inadvertently detached.

Further, in the partition wall 16, openings 16a and 16b for pipes are formed on the right side of the motor 4.

An opening 1a (see Fig. 3) for taking out or mounting or mounting the cartridge 3 is formed in the left portion of the case 1, and a cover (not shown) is freely opened and closed Lt; / RTI > Further, in order to take out or mount the cartridge 3 from the main body of the oxygen concentrator, the cartridge 3 is provided with the handle 19. An oxygen-enriched gas outlet 1b is formed on the surface opposite to the surface on which the opening 1a of the case 1 is formed (i.e., on the right-hand side).

3, in the central portion 3a of the replaceable cartridge 3, there is formed a pair of suction tubes 21 through which a zeolite-based adsorbent for adsorbing nitrogen, for example, Between the adsorption columns 21 is formed an oxygen-enriched gas flow passage 22 through which an oxygen-enriched gas flows and a dilution flow passage 23 through which the diluent gas flows. Further, the pair of adsorption columns 21 are arranged in parallel in the Y-axis direction, and the through holes 21, 22, and 23 extend in the X-axis direction. Although the oxygen-enriched gas flow path 22 and the dilution flow path 23 are shown in FIG. 3 as being arranged in parallel in the Y-axis direction, they are actually arranged in parallel in the direction (Z-axis direction) .

The first cover portion 3b covering the one end portion (right end portion) side of the through holes 21, 22 and 23 covers the right side of the central portion 3a and the second cover portion 3b covering the other end And the portion 3c is provided on the left side of the central portion 3a. The first cover portion 3b is formed with ventilation openings 21a, 22a and 23a (23a overlapped with 22a, not shown) communicating with the through holes 21, 22 and 23, respectively. The second cover portion 3c is provided with a flow path 27 for communicating the other ends of the adsorption cylinder 21 through a flow rate regulating portion 26 as a flow rate regulating means and a check valve 28, And the two flow paths 31 and 32 join together in the middle and the other end of the diluting flow path 23 is connected to the confluent flow path A flow path 33 for communicating is formed. In this manner, the vent holes 21a, 22a, and 23a are provided at the right end of the cartridge 3, and the vent 21a as the vent passage for connecting the flow path switching device is connected to one end (right end) The vent hole 22a serving as the oxygen enriched gas discharge vent is provided with the check valve 28, the flow paths 31 and 32 and the oxygen enriched gas flow path 22 at the other end (left end) of the adsorption cylinder 21 . The ventilation port 23a as the ventilation port for the dilution gas communicates with one end (right end) of the dilution flow passage 23.

The main body side connection port 11 is formed with recesses 36, 37, and 38, respectively, which are fitting holes through which the respective air vents 21a, 22a, and 23a of the cartridge 3 are fitted. The main body side connection port 11 is provided with five ventilation holes in addition to the ventilation holes 36, 37 and 38. The first ventilation hole 41 is communicated with a flow path in the ventilation hole 38 and the main body side connection port 11, And the second vent hole 42 is connected to the switching valve 12 through the flow path in the main body side connection port 11 by the first vent hole 41 and the third and fourth vent holes 43, 44 are communicated with the flow path in the main body side connection port 11 and connected to the switching valve 12 respectively and the fifth vent hole 45 is communicated with the vent hole 37 and the main body side contact hole 11 And is connected to the suction pump 7 for the oxygen-enriched gas. The second to fourth vents 42 to 45 are juxtaposed in the Z-axis direction and are overlapped with each other in Fig. 1 and Fig.

3, the pipe (flow path) for connecting the main body side connection port 11 and the switching valve 12 is connected to the piping opening 16a of the partition wall 16 and the main body side connection port 11 To the suction pump 7 for the oxygen-enriched gas is connected to the piping passage 16b of the partition wall 16. As shown in Fig.

When the cartridge 3 is to be mounted, the cartridge 3 is inserted into the case 1 through the opening 1a of the case 1 and is pushed toward the main body side connection port 11. Then, the vents 21a, 22a, and 23a of the cartridge 3 are connected to the vents 36, 37, and 38 of the main body side connection port 11 on the main body side. On the other hand, when the cartridge 3 is pulled out, when the cartridge 3 is pulled out, the connection between the air vents 21a, 22a, 23a of the cartridge 3 and the air vents 36, 37, It deviates and deviates.

When power is supplied to the oxygen concentrator constructed as described above, the suction pumps 6 and 7 are activated. 2, the suction pumps 6 and 7 are provided at the downstream end of the flow path, so that the flow path upstream of the flow path (i.e., most of the flow paths) becomes negative pressure To flow from the upstream to the downstream.

The air flows from the first vent hole 41 of the filter 2 and the main body side connection port 11 to the flow path in the main body side connection port 11 so that a part thereof flows into the dilution flow path 23 of the cartridge 3 And most of the other flows to the switching valve 12. The switching valve 12 is appropriately switched, but in the state shown in Fig. 2, the air from the filter 2 is introduced into the adsorption column 21 on the left side. When the switching valve 12 is completely replaced from the state shown in Fig. 2, the air from the filter 2 is introduced into the adsorption column 21 on the right side.

Then, the air introduced into the adsorption column 21 is absorbed by the adsorbent, and the oxygen concentration thereof increases to become an oxygen-enriched gas. The oxygen enriched gas flows into the adsorption column 21 on the other side (i.e., the right side) through the flow rate regulating section 26 and the other oxygen enriched gas flows into the adsorption column 21 through the check valve 28 And flows into the oxygen-enriched gas flow path (22). The oxygen enriched gas is diluted with the air from the diluting passage 23 before flowing into the oxygen enriched gas passage 22 and the diluted oxygen enriched gas is introduced into the oxygen enriched gas passage 22 of the cartridge 3, (13), the oxygen concentrate gas suction pump (7) and the check valve (13) to the oxygen-enriched gas outlet (1b). An oxygen suction device 53 such as an oxygen mask or cannula is freely detachably connected to the oxygen-enriched gas outlet 1b, and an oxygen-enriched gas is supplied to the oxygen-

On the other hand, in the adsorption column 21 on the right side, the gas is sucked into the suction pump 6 for nitrogen enrichment gas and becomes a large negative pressure, and the adsorbent releases the adsorbed nitrogen, and a nitrogen-enriched gas is produced. The nitrogen-enriched gas is introduced into the oxygen-enriched gas through the switching valve 12, the check valve 51, the suction pump 6 for the nitrogen-enriched gas, the check valve 51, .

When the switching valve 12 is switched, a nitrogen-enriched gas is generated in the adsorption column 21 on the left side and exhausted through the suction pump 6 for nitrogen enriched gas. On the other hand, in the adsorption column 21 on the right side, Gas is generated and supplied to the oxygen suction tool 53 through the suction pump 7 for oxygen enriched gas.

In this way, adsorption / release of nitrogen is repeated with the adsorbent of the adsorption column 21. Since the adsorbent is deteriorated by repetition of adsorption / discharge of nitrogen, it is necessary to exchange the adsorbent. In order to replace the adsorbent, the cartridge 3 is pulled out to separate it, and the separated cartridge 3 is sent to a retail store, a management factory, or the like. Then, the new cartridge 3 is pushed into the case 1 and mounted. Therefore, the adsorbent can be made new only by replacing the cartridge 3 without sending out the main body of the oxygen concentration apparatus.

The axis of rotation O of the handle 61, that is, the axis of the shaft 62, extends in the Y-axis direction, which is the direction in which the pair of adsorption cylinders 21 are lined. That is, the direction in which the rotation center axis O of the handle 61 extends is a direction perpendicular to the direction in which the adsorption cylinder 21 extends. The handle 61 has a "C" shape, and a circular plate portion 63 is formed integrally with the body of the handle 61 near the bottom of both ends thereof. A guide groove 64 as a guiding portion is formed on the surface of the plate portion 63 on the cartridge 3 side. The guide groove 64 has an introduction portion 64a extending in the radial direction from the periphery and an arcuate portion 64b extending in an arc shape from the end on the rotation center axis O side in the introduction portion 64a have. When the handle 61 is rotated from the cartridge inserting rotational position to the cartridge fixing rotational position, the cartridge 3 is rotated in the direction of the main body O, Side connection port 11 side and is slightly deformed instead of an arc. 7B, the distance AO between the introduction side end A of the introduction portion 64a and the axis O is equal to the distance AO between the end portion B on the side of the arc portion 64b of the introduction portion 64a, And the distance BO between the distal end portion C of the circular arc portion 64b and the axis O is larger than the distance CO between the distal end portion C of the circular arc portion 64b and the center O of the circular arc portion 64b. That is, the distance CO is smaller than the distance AO or the distance BO.

In the second embodiment, the cartridge 3 and the main body side connection port 11 are surrounded by a cartridge protection supporting chassis 71, which is a cover with an opening for inserting the cartridge 3. The cartridge protection supporting chassis 71 is fixed to the board 9 and has an engaging portion 72 protruding from the outer surface thereof to engage with the guide groove 64 of the handle 61. In the state in which the cartridge 3 is mounted, a part of the end of the cartridge protecting support chassis 71 is inserted into a gap between the main body of the cartridge 3 and the plate portion 63, which is the end of the handle 61 .
