However, there is a problem that the suction force acts intensively on the surface of the stored item below the exhaust port, and the surface is adsorbed on the exhaust port, and as a result, it takes a long time to discharge the air in the storage bag. was there. Therefore, in order to prevent the surface of the stored object from blocking the exhaust port, Patent Document 1 proposes a method in which a large number of ribs are provided on the lower surface of the base of the exhaust valve to form an air passage between the ribs. There is. However, since the fabric on the surface of the stored item (for example, a futon) easily enters the air passage between the ribs and the fabric blocks a part of the air passage, it takes time to discharge the air in the storage bag. It takes.

Further, for example, since the canister type vacuum cleaner described in Patent Document 2 uses a high output electric motor, it generates a large amount of heat and is particularly contained in the storage bag in the process of sucking air in the storage bag. There was a problem that it was easy to break down as the atmospheric pressure approached the vacuum.

Further, the canister type vacuum cleaner has a problem that it is large and heavy as an air pump for sucking the air in the storage bag, and is difficult to carry and handle.

Recently, as the number of households living alone has increased, the number of households that do not own a canister type vacuum cleaner has increased, and instead, they own a hand cleaner type electric vacuum cleaner (hereinafter referred to as "hand type vacuum cleaner"). The number of households is increasing. Since the hand-held vacuum cleaner is used by holding it in a human hand, a small small output electric motor is used, and there is a problem that it takes time to suck the air in the storage bag. Further, there is a problem that the suction nozzle attached to the tip of the hand-held vacuum cleaner is thin and does not match the suction valve of the storage bag.

Further, both the canister type vacuum cleaner and the hand type vacuum cleaner have a problem that their uses and functions are limited because they can only suck.

Therefore, the present invention has been made in view of the above problems, and the time required for sucking the air in the storage bag is the same as that of the canister type vacuum cleaner, it is hard to break down, it is compact and lightweight, and it is compact and lightweight. An object of the present invention is to provide a suction / blowing air pump that can be used by switching between suction and blowing from the same mouth, and a suction valve for a storage bag that requires a short time to suck air in the storage bag. do.

Then, as will be described later, the case-side semi-cylindrical partition wall plate 88 is guided by the air entering the introduction port 84 from the central entrance / exit 112 of the flow path switching portion 100 and the inner surface of the outer shell portion 20 on the X− side to flow. The air that has reached the vicinity of the road switching unit 100 is blocked.

Further, the introduction port 84 of the case first component 82 is formed with a first component slit 85, which is a blind-shaped slit, at the opening thereof. The first component slit 85 allows air to pass through when the air entering the introduction port 84 from the central entrance / exit 112 of the flow path switching unit 100 contains foreign matter such as large dust that cannot easily pass through the fan 70. However, it prevents the foreign matter from entering.

Further, as shown in FIG. 8, the case second component 92 has a second component slit 95 so as to surround the first partition plate 94 on the X + side in a semicircular shape. The second component slit 95 prevents foreign matter from entering the suction / blowing air pump 10 from the central entrance / exit 112 when the central entrance / exit 112 of the flow path switching unit 100, which will be described later, is in the blowing state. be.

The flow path switching unit 100 is a member that switches between the connection destination of the inflow flow path of the air flowing into the introduction port 84 and the connection destination of the air discharge flow path guided by the outer shell portion 20. The flow path switching unit 100 is arranged on the lower side of the drive mechanism unit 40 and in the vicinity of the introduction port 84. The flow path switching unit 100 is rotatable with respect to the drive mechanism unit 40. The flow path switching unit 100 includes a dome-shaped main body 110 and an adapter 130 that communicates with the center of the dome-shaped main body 110 and extends in a cylindrical shape in the convex direction of the dome-shaped main body 110. The dome-shaped main body 110 is formed with a central inlet / outlet 112 that is communicated with the adapter 130 and serves as an air inlet / outlet, and an outer inlet / outlet 122 that is located radially outside the central inlet / outlet 112 and serves as an air inlet / outlet. Further, the dome-shaped main body 110 has a second partition plate 114 that covers the central entrance / exit 112 on the concave side of the dome-shaped main body 110 in a quarter spherical shape. The adapter 130 can be attached with a skirt nozzle attachment 150 that spreads like a skirt from the adapter 130 when sucking from the central inlet / outlet 112 by the suction blowout air pump 10, and a tapered nozzle attachment 160 that tapers from the adapter 130 to the tip when blowing out. Is.

The dome-shaped main body 110 of the flow path switching portion 100 has an outer shell portion such that its convexity is directed downward so as to close the lower end side of the outer shell portion 20 from the vertical intermediate position, that is, the vicinity of one end of the outer shell portion 20. It is integrally connected to the inner surface of 20. As a result, the outer shell portion 20 is rotated in the circumferential direction with respect to the handle portion 30 and the drive mechanism portion 40, so that the flow path switching portion 100 is rotated with respect to the handle portion 30 and the drive mechanism portion 40.
The central entrance / exit 112 and the outer entrance / exit 122 formed in the dome-shaped main body 110 are the introduction port 84 and the discharge port 86 of the drive mechanism unit 40 by rotating the outer shell portion 20 with respect to the drive mechanism unit 40. , 96 and the flow path connected to can be switched.

As shown in FIGS. 3 and 4, the outer entrance / exit 122 is formed by cutting out a dome-shaped main body 110 in a semi-arc-shaped fan shape having an overall shape surrounding the central entrance / exit 112. The outer entrance / exit 122 is provided with one or a plurality of blade blades 126 extending in a semicircular shape inside the entire shape so as to follow the overall shape of the fan shape of the semicircle, for example, two blades in parallel in the radial direction. ing.
As shown in FIG. 6A, the blade blade 126 has an L-shaped cross section, one end of the L-shape faces the concave side of the dome-shaped main body 110, and the other end of the L-shaped main body 110 of the dome-shaped main body 110. It is provided facing the outer peripheral side.

Further, as shown in FIGS. 4, 5 and 6, the dome-shaped main body 110 has a cylindrical switching-side cylindrical partition wall plate 116 centered on the central entrance / exit 112 and a switching-side cylindrical partition wall plate on the concave side thereof. It has two switching side bulkheads 118 that divide the 116 into two semi-cylinders so as to pass through the central doorway 112. Further, the dome-shaped main body 110 is provided with screw receivers 119 at three different positions separated by 120 degrees on the inner surface of the outer peripheral edge thereof. The screw receiver 119 is formed so as to coincide with the screw receiver 29 provided on the inner surface of the outer shell portion 20 in a plan view and to fit in a side view. Then, the dome-shaped main body 110, that is, the flow path switching portion 100 is connected to the outer shell portion 20 by connecting the screw receiver 119 and the screw receiver 29 by the screw s.

The radius of curvature of the switching-side cylindrical partition plate 116 coincides with the outermost radius of curvature of the outer entrance / exit 122, and is the radius of curvature of the case-side semi-cylindrical partition plate 88 of the case first component 82. Further, the upper end edge of the switching side cylindrical partition wall plate 116 has the same vertical position as the lower end edge of the case side semi-cylindrical partition wall plate 88, and can slide with each other. Then, as will be described later, the switching side cylindrical partition wall plate 116 guides the air entering the introduction port 84 from the central entrance / exit 112 or the outer entrance / exit 122 of the flow path switching portion 100 to the inner surface of the outer shell portion 20 on the X− side. The air that has reached the vicinity of the flow path switching portion 100 is cut off in combination with the case-side semi-cylindrical partition wall plate 88. Further, the switching side cylindrical partition plate 116 guides the air in the vicinity of the dome-shaped main body 110 in the circumferential direction.

The switching side vertical partition plate 118 is connected to the inner surface and the inner surface of the switching side cylindrical partition plate 116, and is also connected to the second partition plate 114. The switching side partition wall plate 118 does not enter the concave surface side of the second partition wall plate 114, but is continuously connected to the convex surface side along the curved surface. The switching side vertical partition wall plate 118 is sucked or blown out from the central entrance / exit 112 and the air sucked or blown out from the outer entrance / exit 122 in the vicinity of the flow path switching portion 100 and radially inside the switching side cylindrical partition wall plate 116. Shut off from air so that it does not get mixed in. In other words, the switching side vertical partition plate 118 is the air in the vicinity of the dome-shaped main body 110, and the air inside the switching side cylindrical partition plate 116 in the radial direction is on the X + side and the X− side, and the second partition plate 114. Coupled with that, it shuts off.

(Action effect)
The flow path switching unit 100 is arranged at a predetermined rotation position with respect to the drive mechanism unit 40, that is, when the scale of the outer shell portion 20 is aligned with the “IN” of the handle portion 30, that is, the outer entrance / exit 122. Is arranged so as to be on the X + side of the suction / blowing air pump 10, the inflow flow path connected to the air introduction port 84 sucked by the drive mechanism unit 40 is connected to the central inlet / outlet 112, and the drive mechanism unit 40 discharges to the outside. The air discharge channel guided by the shell portion 20 is connected to the outer inlet / outlet 122.
At this time, the second partition plate 114 of the flow path switching unit 100 and the first partition plate 94 of the drive mechanism unit 40 abut each other on the X + side of the suction blowout air pump 10 with a quarter spherical convex surface thereof. Is placed in. In other words, when the central entrance / exit 112 is in the suction state, the second partition plate 114 of the flow path switching portion 100 and the first partition plate 94 of the drive mechanism portion 40 are plane-symmetrical in the vertical direction. When this arrangement state is viewed in the cross-sectional view shown in FIG. 12 cut along the upper and lower X planes passing through the center of rotation, the first partition plate 94 and the second partition plate 114 are arranged so as to be bent in a dogleg shape. The V-shaped X-side forms an air flow path from the central inlet / outlet 112 to the introduction port 84, and the V-shaped X + side blocks the flow path from the outlets 86 and 96. It forms a flow path for air connected to the inlet / outlet 122.

Explaining from the viewpoint of the air air, as shown in FIG. 12, when the central inlet / outlet 112 is in the suction state, the air air entering from the central inlet / outlet 112 makes the X + side of the suction blowout air pump 10 a quarter spherical shape. Guided by the inner surface of the second partition plate 114 that covers the flow path, the dome-shaped main body 110 of the flow path switching portion 100 faces the X- direction. Then, it is guided to the inner surface of the cylindrical partition wall continuously formed by the switching side cylindrical partition wall plate 116 of the dome-shaped main body 110 and the case-side semi-cylindrical partition wall plate 88 of the drive mechanism unit 40, and is guided from the introduction port 84. Air is sucked by the fan 70 rotated by the electric motor 62. At this time, in the dome-shaped main body 110, although not shown in FIG. 12, the switching side vertical partition wall plate 118 blocks the air radially inside the switching side cylindrical partition wall plate 116 on the X + side and the X− side. Therefore, even at a position where the second partition plate 114 does not reach, the sucked air does not flow into the X + side but flows into the introduction port 84. Then, the air is blown out in the radial direction from the discharge ports 86 and 96 of the drive mechanism unit 40, respectively. The blown air is guided along the inner surface of the outer shell portion 20 to the lower side, which is one end side of the outer shell portion. The air that reaches the vicinity of the inner surface of the dome-shaped main body 110 from the discharge port 96 on the X + side is blocked by the dogleg-shaped partition wall formed by the first partition wall plate 94 and the second partition wall plate 114, and reaches the central entrance / exit 112. Does not enter and is discharged from the outer doorway 122 located on the X + side of the dogleg. Also at this time, since the switching side vertical partition plate 118 blocks the air radially inside the switching side cylindrical partition plate 116 on the X + side and the X− side, the air is discharged even at a position where the second partition plate 114 does not reach. The air does not flow out to the X-side, that is, the introduction port 84 or the central entrance / exit 112. Further, the air that has reached the vicinity of the inner surface of the dome-shaped main body 110 from the discharge port 86 on the radial outer side and the X- side of the switching side cylindrical partition plate 116 is the case side semi-cylindrical partition plate 88 and the switching side cylindrical partition plate 116. It is obstructed by the outer surface of the cylindrical partition wall that is continuously formed in the above, and does not flow out to the introduction port 84 or the central entrance / exit 112, but is guided in the circumferential direction to the inner surface of the dome-shaped main body 110 and the outer shell portion 20. It reaches the outer doorway 122 located on the X + side and is discharged from the outer doorway 122.

Therefore, when the flow path switching unit 100 is arranged at a predetermined rotation position with respect to the drive mechanism unit 40, the suction force generated by the drive mechanism unit 40 leads to the air introduction port 84 sucked by the drive mechanism unit 40. Since the inflow flow path is connected to the central inlet / outlet 112 to bring the central inlet / outlet 112 into a suction state, any nozzle attachment, for example, a skirt nozzle attachment 150, can be attached to the tubular adapter 130 communicating with the central inlet / outlet 112. The air in the storage bag B can be sucked from the suction valve 1001 for the storage bag of the storage bag B.

Here, the air discharged from the outer inlet / outlet 122 is changed from the downward flow to the downward direction (downward and radial outward direction) slightly toward the outer peripheral side by the blade blade 126, and the concave portion 22 of the outer shell portion 20. Is discharged to the outside of the suction / blowing air pump 10. Since the air discharged from the outer inlet / outlet 122 passes through the inside or the vicinity of the heated motor unit 60, the temperature may be higher than that of the outside air. Even in this case, it is possible to prevent the high-temperature air discharged from the outer inlet / outlet 122 from adversely affecting the suction valve 1001 or the thermoplastic resin member (unsigned) which is a constituent member of the storage bag B. Then, the discharged air is discharged to the outside of the suction / blowing air pump 10 from the recess 22 of the outer shell portion 20.

On the other hand, when the flow path switching unit 100 is arranged at a predetermined rotation position different from the rotation position with respect to the drive mechanism unit 40, that is, the scale of the outer shell portion 20 is aligned with the “OUT” of the handle portion 30. That is, when the outer inlet / outlet 122 is arranged so as to be on the X- side of the suction / outlet air pump 10, the inflow flow path connected to the air inlet 84 sucked by the drive mechanism unit 40 is connected to the outer inlet / outlet 122. The air discharge flow path discharged by the drive mechanism unit 40 and guided by the outer shell unit 20 is connected to the central inlet / outlet 112.
At this time, the first partition plate 94 of the drive mechanism unit 40 is located on the X + side in the suction / blowing air pump 10, while the second partition plate 114 of the flow path switching unit 100 is arranged on the X− side. In other words, the second partition plate 114 of the flow path switching unit 100 and the first partition plate 94 of the drive mechanism unit 40 are arranged so that their respective quarter spherical convex surfaces are bent. In other words, when the central entrance / exit 112 is in the blowout state, the second partition plate 114 of the flow path switching portion 100 and the first partition plate 94 of the drive mechanism portion 40 are point-symmetrical with respect to the center of rotation. ing. When this arrangement state is viewed in the cross-sectional view shown in FIG. 13 cut along the upper and lower X planes passing through the center of rotation, the first partition plate 94 and the second partition plate 114 are arranged so as to be bent in an S shape. On the S-shaped X-side, an air flow path connecting the outer inlet / outlet 122 to the introduction port 84 is formed, and on the S-shaped X + side, the central inlet / outlet 112 is formed from the discharge ports 86 and 96 that are cut off from the flow path. Form a flow path of air connected to.

Explaining from the viewpoint of the air air, as shown in FIG. 13, when the central inlet / outlet 112 is in the blowing state, the air air entering from the outer inlet / outlet 122 has a quarter spherical shape on the X-side of the suction blowing air pump 10. Guided by the outer surface of the second partition wall plate 114, the switching side cylindrical partition wall plate 116, and the case side semi-cylindrical partition wall plate 88, the dome-shaped main body 110 of the flow path switching portion 100 is directed toward the X + direction (center). At this time, in the dome-shaped main body 110, although not shown in FIG. 13, the switching side vertical partition wall plate 118 blocks the air radially inside the switching side cylindrical partition wall plate 116 on the X + side and the X− side. Therefore, even at a position where the second partition plate 114 does not reach, the sucked air does not flow into the X + side but flows into the introduction port 84. Then, air is sucked from the introduction port 84 by the fan 70 rotated by the electric motor 62. Then, the air is blown out in the radial direction from the discharge ports 86 and 96 of the drive mechanism unit 40, respectively. The blown air is guided along the inner surface of the outer shell portion 20 to the lower side, which is one end side of the outer shell portion. The air that reaches the vicinity of the inner surface of the dome-shaped main body 110 from the discharge port 96 on the X + side is blocked by the S-shaped partition wall formed by the first partition wall plate 94 and the second partition wall plate 114, and reaches the outer entrance / exit 122. Does not enter, but is guided to the inner surface of the dome-shaped main body 110 and is discharged or blown out from the central entrance / exit 112 and the adapter 130 which are located on the S-shaped X + side and communicate with the center of the dome-shaped main body 110. Also at this time, since the switching side vertical partition wall plate 118 shuts off the air between the X + side and the X− side, the discharged air flows out to the X− side, that is, the outer entrance / exit 122 even at a position where the second partition wall plate 114 does not reach. do not do. Further, the air that has reached the vicinity of the inner surface of the dome-shaped main body 110 from the discharge port 86 on the radial outer side and the X- side of the switching side cylindrical partition plate 116 is the case side semi-cylindrical partition plate 88 and the switching side cylindrical partition plate 116. It is obstructed by the outer surface of the cylindrical partition wall that is continuously formed in the above, and does not flow out to the outer entrance 122 or the introduction port 84, and extends to the X + side in the circumferential direction on the inner surface of the dome-shaped main body 110 and the outer shell portion 20. Guided and discharged from the central doorway 112.

Therefore, when the flow path switching unit 100 is arranged at different predetermined rotation positions with respect to the drive mechanism unit 40, the drive mechanism unit 40 is discharged by the blowout output generated by the drive mechanism unit 40 and guided by the outer shell unit 20. Since the discharged air flow path is connected to the central inlet / outlet 112 to bring the central inlet / outlet 112 into a blowout state, the dust accumulated on the object is accumulated by directing the central inlet / outlet 112 to the object to which the blown air is to be applied. , Dust, etc. can be blown off.
Furthermore, by attaching the tapered nozzle attachment 160 to the tubular adapter 130 that communicates with the central entrance / exit 112, the speed of the blown air can be further accelerated, and the dust, dust, etc. accumulated on the object can be blown off more reliably. Can be done.

Since the switching between the suction state and the blowout state can be performed only by rotating the flow path switching unit 100 even while the drive mechanism unit 40 is operating, it is possible at any time according to the user's intention. The central entrance / exit 112, which is the same entrance / exit, can be switched between a suction state and a blowout state.

Further, by attaching an arbitrary nozzle attachment 140 to the adapter 130, it is possible to suck the air in the storage bag B while conforming to the suction valve 1001 of the arbitrary storage bag B at the time of suction, or at the time of blowing out. In, the flow velocity can be accelerated and air can be blown out vigorously. Therefore, even if the electric motor 62 of the drive mechanism unit 40 has a small size and a small output, it is equivalent to a canister type vacuum cleaner by surely sucking the air in the storage bag B from the suction valve 1001 of the storage bag B. The air in the storage bag B can be sucked in the suction time, or the dust, dust, etc. accumulated on the object can be more reliably blown off.

According to the suction / blowing air pump 10, since a small and small output electric motor 62 can be used, the amount of heat generated is small and it is difficult to break down, and the suction / blowing air pump 10 itself is small and lightweight and easy to handle. ..

The compression storage bag 1002 is opened to the outside.

When the skirt nozzle attachment 150 has a large diameter as shown in FIG. 17 or 18, the air in the compression storage bag 1002 can be sucked and discharged in contact with the outer surface of the annular flange 1015 of the cover 1005. ..

Examples of the porous body 1007 include sponges having a large number of open cells, foams such as resins, non-woven fabrics, needle-punched woven fabrics, mesh bodies, and porous sheets. A known mite attractant may be carried on the porous body 1007. As the mite attractant, for example, a pheromone flavor using a fruit extract can be used. As a method of holding the mite attractant in the porous body 1007, for example, there is a method of impregnating the porous body with the liquefied mite attractant and holding the mite attractant.

The porous body 1007 is formed with a central hole 1026 as an insertion hole. On the other hand, the attachment 1008 inserts the central hole 1026 of the porous body 1007 so that the porous body 1007 is attached to the base 1004. Specifically, the mounting tool 1008 has a mounting cylinder 1027, and the mounting cylinder 1027 has a first end portion 1027a and a second end portion 1027b. The first end portion 1027a of the mounting cylinder 1027 is provided with a slit 1028 as an engaging portion that is detachably engaged with the engaged portion 1019 of the rib 1016A arranged in the cross shape of the base 1004. There is. The outer periphery of the first end portion 1027a of the mounting cylinder 1027 is adapted to fit into the inner end of the rib 1016B. Further, a pressing plate 1029 for pressing the porous body 1007 is provided on the second end portion 1027b of the mounting cylinder 1027.

According to the present embodiment, the porous body 1007 has a larger diameter than the base 1004 and covers at least the lower side (lower side and side surface at the time of suction shown in FIG. 14) of the ribs 1016A, 1016B, 1017. , The fabric on the surface of the stored object (for example, a futon) does not get in between the ribs 1016A, 1016B, 1017. Therefore, the fabric does not block or narrow the air passage 1018 between the ribs 1016A, 1016B, 1017. Moreover, since the ventilation path 1018 between the ribs 1016A, 1016B, and 1017 for communicating the inlet of the valve port 1009 of the base 1004 and the porous body 1007 communicates with the porous body 1007 in a very wide area, it is porous. Exhaust through the structure 1007 can be made much smoother. Therefore, exhaust can be reliably performed in a short time.

As a path for discharging the air in the compressed storage bag 1002, as described above, the porous body 1007 is sequentially passed through the ventilation passage 1018 between the ribs 1016A, 1016B and 1017, the valve port 1009 and the first exhaust port 23. The main route is to be discharged to the outside of the compressed storage bag 1002, but there may be a part of the route directly to the ventilation path 1018 without passing through the porous body 1007.
Further, the mounting tool 1008 can be inserted into the central hole 1026 as the insertion hole of the porous body 1007, and the porous body 1007 can be easily attached to the base 1004. Specifically, the mounting cylinder 1027 of the mounting tool 1008 is inserted through the center hole 1026 of the porous body 1007, and the slit 1028 as the engaging portion of the first end portion 1027a of the mounting cylinder 1027 is formed into a cross-shaped rib. The porous body 1007 is pressed by the pressing plate 1029 of the second end portion 1027b of the mounting cylinder 1027 in a state of being engaged with the engaged portion 1019 of the 1016A. As a result, the porous body 1007 can be easily attached to the base 1004. Further, since the porous body 1007 is pressed by the pressing plate 1029, the holding of the porous body 1007 is reliable.

Further, since the engaging portion 1028 is detachably engaged with the rib 1016A arranged in a cross shape, the attachment 1008 can be easily removed from the base 1004. Therefore, the porous body 1007 can be easily attached to and detached from the base 1004, and maintenance work such as cleaning of the porous body 1007 can be easily performed. In addition, the used porous body can be easily replaced with a new porous body.

As described above, the embodiments of the present invention are disclosed in the above description, but the present invention is not limited thereto.
That is, various changes can be made to the above-described embodiments with respect to the mechanism, shape, material, quantity, position, arrangement, etc., without departing from the scope of the technical idea and purpose of the present invention. They are, and they are included in the present invention.

That is, for example, the drive mechanism portion 40 is not fixed to the handle portion 30, but is connected and fixed to the outer shell portion 20, is rotatable with respect to the handle portion 30 together with the outer shell portion 20, and further, a flow path. The switching portion 100 may not be connected to the outer shell portion 20, but may be connected to and fixed to the handle portion 30. Also in this case, due to the rotation of the outer shell portion 20 with respect to the handle portion 30 in the circumferential direction, the positional relationship between the drive mechanism portion 40 and the flow path switching portion 100 becomes the positional relationship shown in FIG. The flow path switching unit 100 switches between the connection destination of the inflow flow path of the air flowing into the introduction port 84 and the connection destination of the air discharge flow path guided by the outer shell portion 20, respectively, and sucks the central inlet / outlet. Alternatively, it can be in a blowing state.

Further, for example, the fan 70 is not limited to the mixed flow fan, and may be a propeller, a turbo fan, or a sirocco fan. Even with these, the fan 70 can suck air from the air inlet 74 and discharge air from the air discharge port 76 by being rectified by the fan hood 72.

Also, for example, the time required to suck the air in the storage bag is the same as that of a canister type vacuum cleaner, it is hard to break down, it is compact and lightweight, and it can be used by switching between suction and blowing from the same mouth. The suction / blowing air pump 10 as possible does not have to include the handle portion 30. That is, the suction / blowing air pump 10 may be configured such that the upper end edge of the outer shell portion 20 is closed and the outer shell portion 20 includes the drive mechanism portion 40.

Further, for example, the number of switching side partition wall plates 118 may be one. However, it is possible to more reliably shut off the air on the inflow flow path side and the air on the discharge flow path side in the vicinity of the flow path switching portion 100 when the number of sheets is more than one.

Further, for example, as shown in FIGS. 17 and 18, the skirt nozzle attachment 150 is formed to have an arbitrary tip diameter according to the diameter of the suction valve provided in the arbitrary storage bag B or the compression storage bag 1002. May be. As a result, even in the storage bag B or the compression storage bag 1002 having an arbitrary suction valve, the air inside the storage bag B or the compression storage bag 1002 can be reliably and quickly sucked by the suction / blowing air pump 10.
