[0001] The present invention relates to an air purification device, and more particularly, to an air purification device capable of filtering air in multiple stages and then discharging it to the outside.
Background Art
[0002] Generally, various air purification devices are used in homes, industrial sites, etc. For example, in a garbage incinerator, a factory chimney, etc., an air purification device is used to remove harmful substances and dust contained in the exhaust gas.
[0003] And in homes as well, an air cleaner is used to maintain a clean environment, and various filters for purifying air are also installed in air conditioners, fan heaters, vacuum cleaners, etc. For example, in a room where a very clean air quality is desired, such as a clean room or a laboratory, a filter-type air purification device is used to remove pathogenic bacteria and fine dust floating in the indoor air.
[0004] However, since conventional air purification devices have a purification structure that depends on filters, the life of the filters is not long, bacteria may breed in the foreign substances collected by the filters, or the foreign substances collected by the filters may be scattered by an external force, contaminating the inside of the device, making it difficult to manage hygienically.
[0005] As a prior art document related to the present invention, there is Patent Document 1: Korean Patent Publication No. 10-2022-0072844 (June 2, 2022), and an air cleaner is disclosed in the said prior art document.

If necessary, the driving of the first pumping unit 200, the second pumping unit 300, the third pumping unit 400, the fourth pumping unit 500, and the fifth pumping unit 600 can also be stopped simultaneously.
[0023] Also, as shown in FIG. 2, a first lid 22 can be coupled to the upper end of the first tank portion 20 so as to be openable and closable. The edge of the first lid 22 can be horizontally seated on the upper end of the first tank portion 20. Although not shown, the lower surface of the first lid 22 and the upper end of the first tank portion 20 may have a structure in which they are coupled in a male-female manner.
[0024] The second tank part 30 has a second auxiliary space 31 with a certain width formed inside so that water W and air A can be introduced. The lower end can be horizontally connected to one side upper surface of the water tank 10, and the lower part of the second auxiliary space 31 communicates vertically with the storage space 11 of the water tank 10.

An installation area can be formed between the first tank part 20 and the second tank part 30 so that a water purification filter part 100 described later is arranged.
[0026] Here, the second tank part 30 can have a hexahedron shape in which four peripheral surfaces along the edge are formed at the same angle and the upper surface and the lower surface are formed horizontally. However, the shape of the second tank part 30 can be variously applied as needed, and the second tank part 30, the first tank part 20, and the water tank 10 can be arranged in the rear area of the base part 1.
[0027] And a plurality of partition plates 32 can be further included, which are horizontally provided inside the second auxiliary space 31 to vertically partition the lower storage space 11 and the second auxiliary space 31, and are arranged at intervals along the vertical direction to partition the second auxiliary space 31 into a plurality of spaces.
[0028] Also, a plurality of through holes 33 can penetrate vertically through the partition plate 32 so that the air A introduced into the storage space 11 can move upward to the uppermost layer of the second auxiliary space 31. That is, when water W and air A are introduced into the storage space 11, the water W is stored in the storage space 11, and the air A immersed in the water W in the storage space 11 can move upward through the through hole 33 and be discharged to the outside of the second tank part 30.
[0029] Also, a second lid 34 can be detachably coupled to the upper end of the second tank part 30 as shown in FIG. 2. The edge of the second lid 34 can be horizontally seated on the upper end of the second tank part 30. Although not shown, the lower surface of the second lid 34 and the upper end of the second tank part 30 can have a structure in which they are coupled in a male-female manner.
[0030] The water purification filter unit 100 is for filtering water W and air A, and one or more (such as three) can be provided at the upper part of the water tank 10 and can be arranged in the installation area formed in the interval between the first tank part 20 and the second tank part 30. Here, inside the water purification filter unit 100, a water purification filter 110 for filtering while allowing water W and air A to pass through can be provided.
[0031] One or more of the upper end and the lower end of these water purification filter units 100 can be connected to each other by a connecting pipe, and the water W and air A flowing into the inlet side can be discharged to the outlet side while passing along the water purification filter 110. The water W and air A that have passed through all the water purification filter units 100 can be introduced into the storage space 11 of the water tank 10 via the fourth connecting line 44 described later.
[0032] The water purification filter 110 can selectively use materials (such as sediment, carbon block, etc.) for filtering foreign substances (such as dust) contained in water W and air A, and the water W and air A that have passed through the water purification filter 110 can be discharged to the outside via the outlet side of the water purification filter unit 100.
[0033] The first pumping unit 200 is provided on the first connecting line 41 that connects the water tank 10 and the first tank part 20, and pumps the water W in the storage space 11 to the first auxiliary space 21 of the first tank part 20.
[0034] The first connecting line 41 has a flow path penetrating along the longitudinal direction, and both sides in the longitudinal direction are respectively connected to the front surface of the water tank 10 and the front surface of the first tank part 20, connecting the storage space 11 and the first auxiliary space 21.
[0035] And the first pumping unit 200 can be fixedly provided in the front area of the base part 1 so as to be located in front of the water tank 10, the first tank part 20, and the second tank part 30. The first pumping unit 200 can use a water pump whose inlet side and outlet side are respectively connected to the first connecting line 41.
[0036] Further, in the front region of the base portion 1, a deck 50 forming one or more layers may be provided with a certain width so that the lower end of the first pumping portion 200 can be fixedly coupled, and the deck 50 may be provided in a state separated from the upper portion of the base portion 1 by a support base 60.
[0037] Also, on the front surface of the first tank portion 20 to which the outlet side of the first connection line 41 is connected, a plurality of injection holes 23 can penetrate in the front-rear direction as shown in FIG. 5. The injection holes 23 are formed with a set diameter so that the air A introduced into the first auxiliary space 21 through the outlet side of the first connection line 41 is injected in the form of fine microbubbles.
[0038] On the other hand, the air purification device according to the present invention may further include one or more ultraviolet sterilization portions 700 provided in the first connection line 41 and irradiating ultraviolet rays UV to the water W moving to the first pumping portion 200, and the ultraviolet sterilization portion 700 can sterilize the water W moving by the pumping pressure of the first pumping portion 200.
[0039] The ultraviolet sterilization portion 700 may have a passage formed therein so that the water W can pass through, and one or more ultraviolet lamps for irradiating ultraviolet rays UV toward the water W when lit may be provided inside the passage, and it may be fixedly provided in the front region of the base portion 1.
[0040] For example, when the first pumping portion 200 is driven, the water W in the storage space 11 moves along the first connection line 41, passes through the passage of the ultraviolet sterilization portion 700, and then may be introduced into the first auxiliary space 21 through the first pumping portion 200. In this process, the water W passing through the passage is sterilized by the ultraviolet rays UV, so that harmful substances contained in the water W can be removed.
[0041] The second pumping unit 300 is connected by the first tank unit 20 and the second connection line 42. After filtering the external air W, it pumps the air into the first auxiliary space 21. On the inlet side of the second pumping unit 300, an air filter 310 may be further included to move the air A to the second pumping unit 300 while filtering it.
[0042] Here, the second connection line 42 has a flow path penetrating along the longitudinal direction, and both sides in the longitudinal direction are respectively connected to the outlet side of the air filter 310 and the front surface of the first tank unit 20 to connect the air filter 310 and the first auxiliary space 21.
[0043] And the second pumping unit 300 may be fixedly provided in the front region of the base unit 1 so as to be located in front of the water tank 10, the first tank unit 20, and the second tank unit 30. The second pumping unit 300 can use an air pump whose inlet side and outlet side are respectively connected to the second connection line 42. The air filter 310 can selectively use various filters to filter foreign substances contained in the air A.
[0044] Also, the lower ends of the second pumping unit 300 and the air filter 310 may be fixedly connected to the upper surface of the base unit 1 or the upper surface of the deck 50. The inlet side of the second pumping unit 300 and the outlet side of the air filter 310 may be connected by another connection pipe, and the inlet side of the air filter 310 can face the front of the base unit 1.
[0045] The third pumping unit 400 is provided on the third connection line 43 that connects the first tank unit 20 and the water purification filter unit 100, and pumps the water W and the air A in the first auxiliary space 21 to the water purification filter unit 100.
[0046] The third connection line 43 has a flow path penetrating along the longitudinal direction, and both sides in the longitudinal direction are respectively connected to the front surface of the first tank unit 20 and the inlet side of the water purification filter unit 100 to connect the water purification filter unit 100 and the first auxiliary space 21.
[0047] And the third pumping unit 400 can be fixedly provided in the front region of the base portion 1 so as to be positioned in front of the water tank 10, the first tank portion 20, and the second tank portion 30. The third pumping unit 400 can use a water pump whose inlet side and outlet side are respectively connected to the third connection line 43.
[0048] Also, the outlet side of the third connection line 43 can be vertically connected to the inlet side formed at the upper end of the purified water filter unit 100. The lower end of the third pumping unit 400 can be fixedly coupled to the upper surface of the base portion 1 or the upper surface of the deck 50.
[0049] The fourth pumping unit 500 is provided in the fourth connection line 44 that connects the purified water filter unit 100 and the water tank 10, and moves the water W and air A that have passed through the purified water filter unit 100 and discharges them into the storage space 11.
[0050] The fourth connection line 44 has a flow path penetrating along the longitudinal direction, and both sides in the longitudinal direction are respectively coupled to the front surface of the water tank 10 and the outlet side of the purified water filter unit 100, connecting the water purification filter unit 100 and the storage space 11.
[0051] And the fourth pumping unit 500 can be fixedly provided in the front region of the base portion 1 so as to be positioned in front of the water tank 10, the first tank portion 20, and the second tank portion 30. The fourth pumping unit 500 can use a water pump whose inlet side and outlet side are respectively connected to the fourth connection line 44. Here, the lower end of the fourth pumping unit 500 can be fixedly coupled to the upper surface of the base portion 1 or the upper surface of the deck 50.
[0052] At this time, the fourth connection line 44 can introduce the water W and the air A into the lower region of the second auxiliary space 31. The air A introduced into the lower region of the second auxiliary space 31 rises and moves into the second auxiliary space 31 through the passage hole 33 of the partition plate 32, and then is discharged to the outside through the fourth connection line 45 described later.
[0053] That is, the air A introduced into the storage space 11 through the fourth connection line 44 rises to the uppermost layer of the second auxiliary space 31 after being immersed in the water W, so that the air A in a state where foreign matters are removed can be discharged into the atmosphere.
[0054] The fifth pumping unit 600 is connected by the second tank unit 30 and the fifth connection line 80, and pumps the air A that has risen to the uppermost layer of the second auxiliary space 31 to the outside of the second tank unit 20.
[0055] The fifth connection line 45 has a flow path penetrating along the longitudinal direction, one side in the longitudinal direction is coupled to the front surface of the second tank unit 20, and the opposite other side is exposed to the atmosphere. At this time, the fifth connection line 45 can discharge the air A in the second auxiliary space 31 into the atmosphere by the pumping pressure of the fifth pumping unit 600.
[0056] And the fifth pumping unit 600 can be fixedly provided in the front region of the base unit 1 so as to be located in front of the water tank 10, the first tank unit 20, and the second tank unit 30. The fifth pumping unit 600 can use an air pump whose inlet side and outlet side are respectively connected to the fifth connection line 45. Here, the lower end of the fifth pumping unit 600 can be fixedly coupled to the upper surface of the base unit 1 or the upper surface of the deck 50.
[0057] Also, a backflow prevention member 610 for preventing the reverse inflow of the air A can be further coupled to the outlet side of the fifth connection line 45 as shown in FIG. 4. The backflow prevention member 610 has an inlet side connected to the outlet side of the fifth connection line 45, and an internal passage 611 can penetrate in the front-rear direction.
[0058] Also, a protruding pipe 612 having an internal through hole penetrating in the front-rear direction so as to protrude from the rear surface of the passage 611 forward and communicate with the flow path of the fifth connection line 45, an opening / closing port 613 protruding forward from the front end of the protruding pipe 612 and having the width of both sides gradually decreasing forward, and a slit hole 614 formed at the front end of the opening / closing port 613, slit in a direction orthogonal to the direction in which the width of the opening / closing port 613 decreases and having a length in the slitting direction may be further included.
[0059] For example, when air A flows in through the rear of the passage 611, the air A that has moved inside the opening / closing port 613 is discharged forward of the protruding pipe 612 while opening the slit hole 614 in the width direction, and the air A discharged through the front of the protruding pipe 612 is discharged forward of the backflow prevention member 610 through the front region of the passage 611.
[0060] At this time, since the opening / closing port 613 has a shape in which the width on both sides decreases toward the front, when air A flows backward to the front of the passage 611, the slit hole 614 is not opened on both sides in the width direction and maintains a close contact state. That is, since air A moves only in the discharge direction of the backflow prevention member 610, air A does not flow backward into the second auxiliary space 31.
[0061] The control unit 800 is for controlling the driving of the first pumping unit 200, the second pumping unit 300, the third pumping unit 400, the fifth pumping unit 600, and the ultraviolet sterilization unit 700 described above, and can be electrically connected to an external power supply unit (not shown), and the operation unit 810 can be electrically connected so that the user can turn the driving on / off.
[0062] On the other hand, the front region of the base portion 1 can be covered by the case 70 from above. The case 70 can have its lower end coupled to the edge side of the front region, and the first pumping unit 200, the second pumping unit 300, the third pumping unit 400, the fifth pumping unit 600, the ultraviolet sterilization unit 700, and the control unit 800 can be located in the internal space of the case 70. Through the slit holes formed in the front surface and one side surface of the case 70, the inlet side of the air filter 310 and the outlet side of the backflow prevention member 610 can be respectively exposed.
[0063] For example, when switching to the drive-on state using the operation unit 810 of the control unit 800, water W in the storage space 11 is introduced into the first auxiliary space 21 by the pumping pressure of the first pumping unit 200, and at the same time, air A in the atmosphere is introduced into the first auxiliary space 21 through the air filter 310 by the pumping pressure of the second pumping unit 300. In this process, the water W moving along the first connection line 41 is sterilized by the ultraviolet sterilization unit 700.
[0064] Next, after the water W and air A in the first auxiliary space 21 are introduced into the inlet side of the water purification filter unit 100 by the pumping pressure of the third pumping unit 400, the water W and air A that have passed through the water purification filter unit 100 are re-introduced into the storage space 11 by the pumping pressure of the fourth pumping unit 500. The air A introduced into the lower region of the second auxiliary space 31 moves upward to the uppermost layer of the first auxiliary space 31 through the passage hole 33 of the partition board 32, and the air A in the first auxiliary space 31 is discharged into the atmosphere by the pumping pressure of the fifth pumping unit 600.
[0065] As a result, the present invention can improve the air purification performance by filtering the externally inhaled air A in multiple stages. Since the water W is introduced together with the air A in a sterilized state, harmful substances contained in the water W can be removed. The collected foreign substances (such as dust) do not flow out to the outside, enabling hygienic management.
[0066] As described above, specific embodiments of the air purification device according to the present invention have been described. However, various implementation variations are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be construed as being limited to the described embodiments, but is defined not only by the following claims but also by equivalents thereof. That is, the foregoing embodiments are illustrative in all respects and not restrictive. The scope of the present invention is indicated by the following claims rather than the detailed description. All changes or variations derived from the meaning and scope of the claims and their equivalent concepts are included in the scope of the present invention.
