[0020] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. However, the present invention is not limited to this embodiment. Fig. 1(a) is a perspective view of a liquid processing unit according to the present invention, and Fig. 1(b) is a cross-sectional view taken along line AA in Fig. 1(a). Fig. 1(c) is an enlarged cross-sectional view of a portion of Fig. 1(b), in which the flow of liquid and air is indicated by arrows. An overview of the liquid processing unit according to the present invention will be described below using these figures.

[0021] In the liquid processing unit 10, a connecting pipe 2 extending from a housing 1 is detachably attached to the tip of a suction pipe provided in a suction device (not shown). Therefore, various commercially available vacuum cleaners or the like can be used as suction devices with the suction nozzle and extension pipe removed.

[0022] The liquid treatment unit 10 comprises a housing 1 connectable to a suction pipe, a liquid treatment filter body 3 formed in the housing 1, an air treatment filter body 4 formed in the housing 1 downstream of the liquid treatment filter body 3, an extension pipe 5 extending outward from the housing 1 upstream of the liquid treatment filter body 3, and a suction port 6 provided at the tip of the extension pipe 5.

[0023] The housing 1 is composed of a housing main body 1a and a cup body 7 containing a liquid treatment filter body 3, and the extension tube 5, the liquid treatment filter body 3, and the cup body 7 are removably fixed to the housing main body 1a.

[0024] The liquid processing unit 10 of the present invention can prevent the housing main body 1a from being contaminated even if liquid seeps out of the liquid processing filter body 3, by having the cup body 7 enclose the liquid processing filter body 3.

[0025] Furthermore, since the extension tube 5, the liquid treatment filter body 3, and the cup body 7 are removably fixed to the housing main body 1a, the replacement of the liquid treatment filter body 3 can be easily performed, and the cleaning of the extension tube 5 and the cup body 7 can be performed in a short time.

[0026] The extension tube 5 has a straight member 5a and a bending member 5b, and the bending member 5b has a structure in which one end fits into the straight member 5a and the other end fits into the liquid treatment filter body 3, and the bending member 5b, or the bending member 5b and the liquid treatment filter body 3 as a whole, are detachable from the housing 1. This allows the straight member 5a and the bending member 5b of the extension tube to be removed from the housing 1 in a separated state, facilitating attachment / detachment, cleaning, and disposal / attachment of the liquid treatment filter body 3.

[0027] Furthermore, the liquid-material treatment unit 10 of the present invention is arranged so that the longitudinal direction of the straight member 5a of the extension pipe and the longitudinal direction of the liquid-material treatment filter body 3 are approximately parallel, and the liquid-material treatment filter body 3 is positioned below the bent member 5b of the extension pipe during use. This prevents the liquid collected in the liquid-material treatment filter body 3 from flowing back toward the suction port 6 and contaminating the floor surface, etc.

[0028] As shown in Figure 1(c), when in use, liquid material is sucked by the suction device and passes from the suction port 6 through the extension tube 5 and is collected in the liquid treatment filter body 3. The suction port 6 is surrounded on two sides by airflow sealing means 6a made of synthetic resin, and the liquid material is sucked into the suction port 6c through an opening 6b formed at the rear.

[0029] In addition, the air passing through the liquid treatment filter body 3 passes through the gap formed between it and the cup body 7, passes through the air treatment filter body 4, and then passes through the deodorizer 8a installed in the deodorizer installation frame 8, and is sucked into the suction pipe of the suction device through the connecting pipe 2.

[0030] 2(a) is a perspective view of the cup body 7 removed from the housing body. The liquid-material treatment filter body 3 contained in the cup body 7 is detachably fixed to the cup body 7 via a partition body 9. This allows the liquid-material treatment filter body 3 to be removed from the housing body 1a while still contained in the cup body 7 and transported to a disposal location, preventing contamination of floors, etc., even if liquid seeps out from the liquid-material treatment filter body 3 during transportation.

[0031] 2(b) is a perspective view of the cup body. The cup body 7 has a cylindrical cup portion 7a that houses the liquid treatment filter body 3 and an opening 7b, and the opening 7b is formed with a hook 7c and a protrusion 7d that fit with the housing body. This allows the cup body 7 to be detachably fixed to the housing body.

[0032] 2(c) is a perspective view of the liquid-treatment filter body. The liquid-treatment filter body 3 includes a bag-shaped member 3a and an attachment plate 3c with an opening 3b. The bag-shaped member 3a is formed by overlapping four layers of breathable nonwoven fabric and contains a water-absorbent polymer. The attachment plate 3c is made of cardboard, and three points on its edge are engaged with engagement portions 9b, 9c, and 9d of the partition body 9.

[0033] 2(d) is a perspective view of the partition body. The partition body 9 includes a partition wall 9a with a U-shaped cross section, locking portions 9b, 9c, and 9d formed at one end of the partition wall 9a, and a fitting portion 9e that fits into the opening 7b of the cup body 7. The partition body 9 also defines gaps 9f and 9g between the left and right sides of the cup body 7 and the liquid-treatment filter body 3, and a gap 9h between the cup body 7 and the upper side of the liquid-treatment filter body 3. This ensures a sufficient air passage, and the gap 9i between the cup body 7 and the lower side of the liquid-treatment filter body 3 is blocked by a wall (not shown) formed on the housing body side, preventing the entire housing body from being contaminated by liquid leaking into the cup body 7.

[0034] Fig. 3 is a perspective view showing the liquid treatment unit with the lid constituting the housing body open. Fig. 4(a) is a perspective view of the air treatment filter body, and Fig. 4(b) is a perspective view showing the liquid treatment unit with the lid constituting the housing body open and the air treatment filter body and bending member removed. Fig. 4(c) is a perspective view of the bending member constituting the extension tube. The following describes the attachment and detachment of the air treatment filter body and bending member in the liquid treatment unit according to the present invention, using these figures.

[0035] In the housing body 1a of the liquid treatment unit 10 of the present invention, a lid 11 and a frame 12 are connected via a hinge 13, and the lid 11 and the frame 12 are structured so that they can be opened and closed by hooking a rotating ring 14 provided on the frame 12 onto a hook 15 on the lid 11. With the lid 11 open, the air treatment filter body 4 attached to the lid 11 side can be attached and detached, and the bending member 5b attached to the frame 12 side can also be attached and detached. This makes it easy to clean the air treatment filter body 4 and the bending member 5b.

[0036] The air treatment filter body 4 is formed of a plate-shaped filter member 4a and a lattice-shaped frame member 4b, and a deodorizer installation frame 8 is formed as part of the downstream surface of the air treatment filter body 4. This makes it possible to purify air contaminated by liquid substances, and by installing a deodorizer in the deodorizer installation frame 8, it is possible to remove the smell of gases generated from the liquid substances.

[0037] Furthermore, the air treatment filter body 4 is detachable from the housing 1, and also serves as an opening and closing lid for the deodorizer installation frame 4. This makes it easy to clean the air treatment filter body 4, and eliminates the need to provide a separate opening and closing lid for the deodorizer installation frame 8, thereby reducing manufacturing costs and allowing the housing 1 to have a compact shape.
