Description

  The present invention relates to a suction blowout air pump capable of switching between suction and blowout of air, and a suction valve for a storage bag used to suction and exhaust air in a storage bag.

  2. Description of the Related Art Conventionally, household canisters for storing clothes, bedding, etc. (hereinafter referred to as "stored items") in a storage bag in a general household, and thereafter sucking air in the storage bag to compress stored items. Type electric vacuum cleaners (hereinafter referred to as "canister type vacuum cleaners") are used.

  The storage bag is usually provided with a suction valve having an exhaust port.

  However, the suction force acts intensively on the surface of the storage under the exhaust port, the surface is adsorbed to 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 closing 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 material on the surface of the stored item (for example, a futon) can easily enter the air passage between the ribs and a part of the air flow path is blocked by the material, it takes time to discharge the air in the storage bag. I need it.

  Also, for example, the canister type vacuum cleaner described in Patent Document 2 uses a high output electric motor, and thus generates a large amount of heat, and particularly in the storage bag in the process of sucking the air in the storage bag. There is a problem that as the air pressure approaches a vacuum, it is more likely to fail.

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

  In addition, recently, with the increase of single-living households, households that do not possess a canister type vacuum cleaner are increasing, and instead, a hand cleaner type electric vacuum cleaner (hereinafter referred to as "hand type vacuum cleaner") is owned. Households are increasing. The hand type vacuum cleaner has a problem that it takes a long time to suck the air in the storage bag because a small and small output electric motor is used because it is held by human hands and used. Furthermore, the suction nozzle attached to the tip of the hand type vacuum cleaner is thin and has a problem that it does not match the suction valve of the storage bag.

  In addition, there is a problem that the use and function of the canister type vacuum cleaner or the hand type vacuum cleaner are limited because only the suction can be performed.

  Therefore, the present invention has been made in view of the above problems, and the time required for suctioning the air in the storage bag is equivalent to that of a canister type vacuum cleaner, is less likely to break down, and is compact and lightweight, An object of the present invention is to provide a suction blowout air pump capable of switching between suction and blowout from the same port and a suction valve for a storage bag in which the time required for suctioning air in the storage bag is short. Do.

  The suction blowout air pump according to the present invention has an electric motor and a fan, has an inlet for introducing air to the fan, an outlet for discharging air blown out from the fan, and is rotated by the electric motor. A drive mechanism that blows out air sucked from the inlet by the fan radially outward from the discharge port, and is formed in a substantially cylindrical shape, and is disposed to cover the drive mechanism in a nested manner with an appropriate interval. And an outer shell portion for guiding the air blown out radially outward from the discharge port to one end along the inner surface, and a connection destination of the inflow path of the air flowing into the introduction port and the outer shell portion And a flow path switching unit for switching between the air discharge flow path and the connection destination of the air flow path, wherein the flow path switching unit is in communication with the dome-like main body and the center of the dome-like main body and is dome-like Cylindrical toward convex direction of main body And an extending adapter, which is rotatable with respect to the drive mechanism, and the dome-like main body is in communication with the adapter to be an air inlet and outlet, and an air located at a radially outer side than the air inlet and outlet. An outer inlet / outlet serving as an inlet / outlet of the flow passage is formed, and the flow passage switching portion connects the inflow flow passage leading to the introduction port of the air suctioned by the drive mechanism portion when disposed at a predetermined rotational position with respect to the drive mechanism portion. The central inlet / outlet is brought into a suction state by connecting to the central inlet / outlet and connecting the exhaust passage of the air guided by the outer shell portion to the outer inlet / outlet, and the rotational position is different from the rotational position with respect to the drive mechanism. When disposed at a predetermined rotational position, the inflow channel connected to the inlet of the air sucked by the drive mechanism is connected to the outer port, the drive mechanism is discharged, and the discharge channel of the air guided by the outer shell is Center entry and exit And blowing state central doorway by connecting to, characterized in that a suction outlet air pump.

When the drive mechanism portion is disposed at a predetermined rotational position, the inflow flow path connected to the inlet port of the air to be sucked by the drive mechanism portion is connected to the center port and the drive mechanism portion is discharged and guided by the outer shell portion Since the central inlet / outlet is brought into the suction state by connecting the air discharge flow path to the outer inlet / outlet, the optional nozzle attachment is attached to the cylindrical adapter communicated with the central inlet / outlet by the suction force generated by the drive mechanism. Thus, air in the storage bag can be suctioned from the storage bag suction valve for any storage bag. That is, the storage items stored in any storage bag can be compressed.

  Furthermore, according to the suction blowout air pump according to the present invention, when the flow path switching unit is disposed at a predetermined rotation position different from the rotation position with respect to the drive mechanism unit, the flow passage switching unit The central inlet / outlet is brought out by connecting the inflow passage connected to the inlet to the outer inlet / outlet port and connecting the discharge passage of the air guided by the outer shell portion to the central inlet / outlet by the drive mechanism portion. By directing the central entrance to an object to which air is to be applied, dust, dirt and the like accumulated on the object can be blown away.

  Furthermore, according to the suction blow-out air pump according to the present invention, the flow path switching unit is set to a predetermined rotational position or a rotational position different from the rotational position with respect to the drive mechanism, that is, to the drive mechanism. By being rotated relative to each other, it is possible to switch between the connection destination of the inflow channel of the air flowing into the inlet and the connection destination of the discharge channel of the air guided by the outer shell, and this switching is a drive mechanism Since it is possible only by rotating the flow path switching unit even while the unit is in operation, it is possible to switch between the suction and discharge states at any time and use the center port, which is the same port. .

At the time of suction, it is possible to suction only the air in the storage bag without suctioning the outside air while conforming to the suction valve of any storage bag, or at the time of blowout, accelerate the flow velocity to force air vigorously. It can blow out. Therefore, even if the electric motor of the drive mechanism portion has a small size and a small output, by suctioning the air in the storage bag from the suction valve of the storage bag with certainty, the storage bag has a suction time equivalent to that of a canister type vacuum cleaner. It is possible to suction the air inside, or more reliably blow away the dust, dust and the like accumulated on the object.

  Furthermore, according to the suction blowout air pump according to the present invention, since a small and small output electric motor can be used, the amount of heat generation is small and it becomes difficult to break down, and the suction blowout air pump itself becomes small and lightweight. It is easy.

  The suction blowout air pump according to the present invention further includes a handle portion constituting the uppermost portion, and the dome-shaped main body of the flow path switching portion is integral with the inner surface of the outer shell portion so as to close one end of the outer shell portion. And the outer shell portion rotatably connects the other end edge to the handle portion, the drive mechanism portion is connected to the handle portion, and the flow path switching portion rotates the outer shell portion relative to the drive mechanism portion It is also possible to switch the connection destination of the inflow passage and the connection destination of the discharge passage by being switched.

The outer shell portion rotatably connects the other end edge to the handle portion, the drive mechanism portion is connected to the handle portion, and the flow path switching portion has an outer shell portion to the drive mechanism portion Since it is possible to switch the connection destination of the inflow passage and the connection destination of the discharge passage by being rotated, the user does not touch the flow passage switching portion which is to be positioned on the bottom side of the suction blowout air pump. In either case, by rotating the outer shell portion with respect to the handle portion, the flow path switching portion can be rotated with respect to the drive mechanism portion, and it is possible to switch between the suction state and the blowout state of the center inlet and outlet of the flow path switching portion.

  In the suction / blowing air pump according to the present invention, the outer inlet / outlet port is formed by cutting out the dome-like main body in a semicircular arc fan shape so as to surround the central inlet / outlet. One or more blade wings extending in a semicircular arc shape are provided in parallel inside the overall shape, the blade wings are formed in an L shape in cross section, and one end of the L shape faces the concave side of the dome shaped body The other end of the L-shape may be provided toward the outer peripheral side of the dome-like main body.

  According to the suction blowout air pump according to the present invention, the outer entrance and exit is formed by cutting out the dome-like main body in the shape of a semicircular arc that surrounds the center entrance and exit. The suctioned air is discharged radially outward from the center port at one time, and one or a plurality of blade blades extending in the shape of a semicircular arc along the entire shape of the semicircular arc fan in a semicircular arc shape Provided side by side, the blade wing is formed to have an L-shaped cross section, one end of the L-shape facing the concave side of the dome-like body, and the other end of the L-shape facing the outer circumferential side of the dome-like body Thus, the air discharged from the outer inlet / outlet can be discharged obliquely toward the outer peripheral side. Therefore, it is possible to avoid that the high temperature air discharged from the outer inlet / outlet adversely affects the suction valve or the thermoplastic resin member which is a component of the storage bag.

The case-side semi-cylindrical partition plate 88 is guided by the air entering the inlet 84 from the center entrance 112 of the flow path switching unit 100 and the inner surface on the X− side of the outer shell 20 as described later. The air that has reached the vicinity of the road switching unit 100 is shut off.

  Further, the inlet 84 of the case first component 82 is formed with a first component slit 85 which is a bowl-shaped slit at the opening thereof. The first component slit 85 allows air to pass through when air entering the inlet 84 from the center inlet / outlet 112 of the flow path switching unit 100 contains foreign matter such as large dust that can not easily pass through the fan 70. However, it prevents the entry of foreign matter.

  Furthermore, 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 in a semicircular arc shape on the X + side. The second component slit 95 prevents foreign matter from entering the suction blowout air pump 10 from the center entrance 112 when the center entrance 112 of the flow path switching unit 100 described later is in a blowout state. is there.

  The flow path switching unit 100 is a member that switches the connection destination of the inflow path of the air flowing into the inlet 84 and the connection destination of the discharge flow path of the air guided by the outer shell 20. The flow path switching unit 100 is disposed below the drive mechanism 40 and in the vicinity of the inlet 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 communicating with the center of the dome-shaped main body 110 and extending in a cylindrical shape in a convex direction of the dome-shaped main body 110. The dome-shaped main body 110 is formed with a central inlet / outlet 112 communicated with the adapter 130 and serving as an air inlet / outlet, and an outer inlet / outlet 122 located radially outward of the central inlet / outlet 112 and serving as an air inlet / outlet. In addition, the dome-shaped main body 110 has a second partition plate 114 that covers the center entrance 112 on the concave side of the dome-shaped main body 110 in a quarter sphere. The adapter 130 can attach a skirt nozzle attachment 150 that spreads like a skirt from the adapter 130 when suctioning from the center port 112 by the suction blowout air pump 10, and can attach a tapered nozzle attachment 160 that narrows from the adapter 130 to the tip when blowing. It is.

The dome-shaped main body 110 of the flow path switching unit 100 has the convex portion facing downward, and the outer shell portion so as to close the lower end side, that is, one end vicinity of the outer shell portion 20 than the intermediate position in the vertical direction of the outer shell portion 20. It is integrally connected to the inner surface of 20. As a result, when the outer shell portion 20 is rotated in the circumferential direction with respect to the handle portion 30 and the drive mechanism portion 40, the flow path switching portion 100 is rotated with respect to the handle portion 30 and the drive mechanism portion 40.
The central entrance 112 and the outer entrance 122 formed in the dome-shaped main body 110 are configured such that the outer shell 20 rotates with respect to the drive mechanism 40 to introduce the inlet 84 and the outlet 86 of the drive mechanism 40. , 96 can be switched.

As shown in FIG. 3 and FIG. 4 and the like, the outer entrance 122 is formed by cutting out the dome-shaped main body 110 in the shape of a semicircular arc that surrounds the center entrance 112. The outer inlet / outlet port 122 is provided with one or a plurality of, for example, two, blade wings 126 extending in the shape of a semicircular arc along the entire shape of the semicircular arc fan-shaped along the radial direction. ing.
The blade wing 126 is L-shaped in cross section as shown in FIG. 6A, one end of the L-shape faces the concave side of the dome-like main body 110 and the other end of the L-shape faces the dome-like main body 110. It is provided facing the outer peripheral side.

  Furthermore, as shown in FIG. 4, FIG. 5 and FIG. 6, on the concave side of the dome-like main body 110, a cylindrical switching side cylindrical partition plate 116 centering on the center entrance 112 and its switching side cylindrical partition plate And two switching side vertical partition plates 118 which divide 116 into two half cylinders so as to pass through the center entrance 112. Further, the dome-shaped main body 110 is provided with screw receptacles 119 at three different positions separated by 120 degrees on the inner surface of the outer peripheral edge thereof. The screw receptacle 119 is formed to coincide with the screw receptacle 29 provided on the inner surface of the outer shell 20 in plan view and to fit in side view. Then, in the dome-shaped main body 110, that is, the flow path switching unit 100, the screw receptacle 119 and the screw receptacle 29 are connected by the screw s, and are connected to the outer shell 20.

  The radius of curvature of the switching side cylindrical partition plate 116 matches the radius of curvature of the outermost side of the outer entrance / exit port 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 plate 116 can be slid relative to the lower end edge of the case side semi-cylindrical partition plate 88 at the same vertical position. The switching side cylindrical partition plate 116 guides the air entering the inlet 84 from the center entrance 112 or the outside entrance 122 of the flow path switching unit 100 and the inner surface on the X− side of the outer shell 20 as described later. Thus, the air that has reached the vicinity of the flow path switching unit 100 is blocked in combination with the case-side semi-cylindrical partition plate 88. Furthermore, the switching side cylindrical partition plate 116 guides air in the vicinity of the dome-shaped main body 110 in the circumferential direction.

  The switching side standing partition plate 118 is connected to the inner surface and the inner surface of the switching side cylindrical partition plate 116 and is connected to the second partition plate 114. The switching side standing partition plate 118 does not enter the concave side of the second partition plate 114, and is connected continuously along the curved surface on the convex side. The switching side standing partition plate 118 is sucked or blown out from the outside inlet / outlet 122 with air sucked or blown out from the center inlet / outlet 112 in the vicinity of the flow path switching unit 100 and radially inner than the switching side cylindrical partition plate 116 Shut off with air, so as not to mix. In other words, the switching side standing partition plate 118 is the air in the vicinity of the dome-shaped main body 110, and the air radially inward of the switching side cylindrical partition plate 116 is divided into the X + side and the X − side. Couple with, shut off.

(Action effect)
When the flow path switching unit 100 is disposed at a predetermined rotational position with respect to the drive mechanism unit 40, that is, when the scale of the outer shell unit 20 is aligned with “IN” of the handle unit 30, that is, the outer entrance 122 Is arranged to be on the X + side of the suction blowout air pump 10, the inflow passage connected to the inlet 84 of the air to be sucked by the drive mechanism 40 is connected to the center inlet 112 and the drive mechanism 40 is discharged The discharge passage of the air guided by the shell 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 on their quarter spherical convexes on the X + side in the suction blowout air pump 10. Is arranged. 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 when the central entrance 112 is in the suction state are plane symmetrical in the vertical direction. The first partition plate 94 and the second partition plate 114 are arranged to be bent in a V-shape when viewed in the cross-sectional view shown in FIG. The X-side of the V-shape forms a flow path of air connected from the center inlet / outlet 112 to the inlet 84, and the X + side of the V-shape cuts off the flow path outside the exhaust port 86, 96 A flow path of air connected to the inlet / outlet 122 is formed.

  Explaining from the viewpoint of air air, as shown in FIG. 12, when the center inlet / outlet 112 is in the suction state, the air air entering from the center inlet / outlet 112 has a quarter spherical shape on the X + side of the suction outlet air pump 10. It is guided by the inner surface of the covering second partition plate 114 and directed in the X-direction of the dome-shaped main body 110 of the flow path switching unit 100. Then, it is guided by the inner surface of the cylindrical partition formed continuously by the switching side cylindrical partition plate 116 of the dome-shaped main body 110 and the case-side semi-cylindrical partition plate 88 of the drive mechanism 40, and The air is drawn 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 switch side vertical partition plate 118 blocks air radially inside the switch side cylindrical partition plate 116 between the X + side and the X− side. Therefore, even at a position where the second partition plate 114 does not extend, the air to be sucked does not flow into the X + side, but flows into the inlet 84. Then, the air is blown radially outward from the discharge ports 86 and 96 of the drive mechanism 40. The blown out air is guided along the inner surface of the outer shell 20 to the lower side which is one end side of the outer shell. The air that has reached the vicinity of the inner surface of the dome-like main body 110 from the discharge port 96 at the X + side is blocked by the letter-like partition formed by the first partition plate 94 and the second partition plate 114 and Does not enter and is discharged from the outer entrance 122 located on the X + side of the V-shape. Also at this time, since the switching side standing partition plate 118 blocks the air radially inward of the switching side cylindrical partition plate 116 between the X + side and the X− side, discharge is performed even at a position where the second partition plate 114 does not extend. Air does not flow out to the X-side, i.e., the inlet 84 or the center port 112. Further, air that has reached the inner surface of the dome-like main body 110 from the discharge port 86 radially outward of the switching side cylindrical partition plate 116 and on the X− side is the case side semi-cylindrical partition plate 88 and the switching side cylindrical partition plate 116 And is not guided to the inlet port 84 or the center port 112, and is guided circumferentially to the inner surface of the dome-like main body 110 and the outer shell 20, It reaches the outer entrance 122 located on the X + side, and is discharged from the outer entrance 122.

  Therefore, when the flow path switching unit 100 is disposed at a predetermined rotational position with respect to the drive mechanism 40, the flow passage switching unit 100 is connected to the inlet 84 for the air sucked by the drive mechanism 40 by the suction force generated by the drive mechanism 40. Since the inflow channel is connected to the center inlet / outlet 112 and the center inlet / outlet 112 is in a suction state, any nozzle attachment such as the skirt nozzle attachment 150 is attached to the cylindrical adapter 130 communicating with the center inlet / outlet 112. The air in the storage bag B can be sucked from the storage bag suction valve 1001 of the storage bag B.

  Here, the air discharged from the outer inlet / outlet port 122 is diverted downward (downward and radially outward) from the downward flow toward the outer peripheral side by the blade wing 126, and the recess 22 of the outer shell portion 20 Then, the air is discharged to the outside of the suction blowout 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, it may be hotter than the outside air. Also in this case, it is possible to avoid that the high temperature air discharged from the outer inlet / outlet 122 adversely affects the suction valve 1001 which is a component of the storage bag B or the thermoplastic resin member (without the reference numeral). Then, the discharged air is discharged from the concave portion 22 of the outer shell portion 20 to the outside of the suction blowout air pump 10.

On the other hand, when the flow path switching unit 100 is disposed at a predetermined rotational position different from the rotational position with respect to the drive mechanism 40, that is, the scale of the outer shell 20 is aligned with the “OUT” of the handle 30. In other words, when the outer outlet port 122 is disposed on the X− side of the suction outlet air pump 10, the inflow channel connecting to the inlet port 84 of the air sucked by the drive mechanism 40 is connected to the outer outlet port 122 The drive mechanism 40 discharges and connects the discharge passage of the air guided by the shell 20 to the center port 112.
At this time, while the first partition plate 94 of the drive mechanism 40 is positioned on the X + side in the suction blowout air pump 10, the second partition plate 114 of the flow path switching unit 100 is disposed 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 such that the respective quarter spherical convexes are bent. Furthermore, 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 when the center inlet / outlet 112 is in the blowout state are point symmetrical with respect to the rotation center. ing. When this arrangement state is seen in the cross-sectional view shown in FIG. 13 which is cut at the upper and lower X planes passing through the rotation center, the first partition plate 94 and the second partition plate 114 are arranged in an S-shape. The flow path of the air connected from the outer inlet / outlet 122 to the inlet 84 at the S-shaped X-side is formed, and the central inlet / outlet 112 from the discharge ports 86 and 96 which block the flow path at the X + side of the S-shape. Form a flow path of air connected to the

  To explain from the viewpoint of the air air, as shown in FIG. 13, when the center inlet / outlet port 112 is in the blowout state, the air air entering from the outer inlet / outlet port 122 has a quarter sphere on the X− side of the suction blowout air pump 10 Is guided by the outer surface of the second partition plate 114 and the switch-side cylindrical partition plate 116 and the case-side semi-cylindrical partition plate 88, and travels in the X + direction (center) of the dome-shaped main body 110 of the flow path switching unit 100. At this time, in the dome-shaped main body 110, although not shown in FIG. 13, the switching side vertical partition plate 118 blocks air radially inward of the switching side cylindrical partition plate 116 between the X + side and the X- side. Therefore, even at a position where the second partition plate 114 does not extend, the air to be sucked does not flow into the X + side, but flows into the inlet 84. Then, the air is sucked from the inlet 84 by the fan 70 rotated by the electric motor 62. Then, the air is blown radially outward from the discharge ports 86 and 96 of the drive mechanism 40. The blown out air is guided along the inner surface of the outer shell 20 to the lower side which is one end side of the outer shell. The air that has reached the vicinity of the inner surface of the dome-like main body 110 from the outlet 96 at the X + side is blocked by the S-shaped partition formed by the first partition plate 94 and the second partition plate 114 and It does not enter, but is guided by the inner surface of the dome-like body 110 and discharged or blown out from the central entrance 112 and adapter 130 located on the X + side of the S-shape and in communication with the center of the dome-like body 110. Also at this time, since the switching side partition wall plate 118 blocks the air between the X + side and the X− side, the discharged air flows out to the X− side, that is, the outer inlet / outlet 122 even at a position where the second partition plate 114 does not reach. do not do. Further, air that has reached the inner surface of the dome-like main body 110 from the discharge port 86 radially outward of the switching side cylindrical partition plate 116 and on the X− side is the case side semi-cylindrical partition plate 88 and the switching side cylindrical partition plate 116 And is not blocked by the outer surface of the cylindrical partition formed continuously, and does not flow out to the outer inlet / outlet port 122 or the inlet port 84, to the inner surface of the dome-shaped main body 110 and the outer shell portion 20 circumferentially to the X + side. It is guided and discharged from the central entrance 112.

Therefore, when the flow path switching unit 100 is disposed at a different predetermined rotational position with respect to the drive mechanism unit 40, the drive mechanism unit 40 is discharged by the blowing output generated by the drive mechanism unit 40 and guided by the outer shell 20 Since the discharge passage of the stored air is connected to the central inlet 112 and the central inlet 112 is brought into the blowout state, dust directed to the object to which the blown air is to be applied is directed to the dust. Dust can be blown away.
Furthermore, by attaching the tapered nozzle attachment 160 to the cylindrical adapter 130 in communication with the central inlet / outlet 112, the speed of the blown-out air is further accelerated to more reliably blow away dust, dirt and the like accumulated on the object. Can.

  The switching between the suction state and the blowout state is possible only by rotating the flow path switching unit 100 even while the drive mechanism unit 40 is in operation, and therefore, at any time according to the intention of the user The central entrance 112, which is the same entrance, can be switched between the suction state and the blowing state for use.

  In addition, by attaching an optional nozzle attachment 140 to the adapter 130, the air in the storage bag B can be sucked while conforming to the suction valve 1001 of any storage bag B at the time of suction, or at the time of blowout The air flow can be accelerated and the air can be blown out vigorously. Therefore, even if the electric motor 62 of the drive mechanism 40 has a small size and a small output, by suctioning the air in the storage bag B from the suction valve 1001 of the storage bag B with certainty, it is equivalent to a canister type cleaner. The air in the storage bag B can be sucked in the suction time, or dust, dirt and the like accumulated on the object can be more reliably blown off.

  According to the suction blowout air pump 10, since the small and small output electric motor 62 can be used, the amount of heat generation becomes small and it becomes difficult to break down, and the suction blowout air pump 10 itself becomes small and light and easy to handle .

Therefore, the valve port 1009 is divided into a plurality of radial support ribs 1011.

The check valve 1006 is formed of, for example, an elastic body made of rubber such as silicone rubber. The check valve 1006 comprises a generally flat central portion 1012 received by the valve holding portion 1010 and a conical portion 1013 extending downwardly from the central portion 1012.

It is in contact. The check valve 1006 is strongly pressed against the valve seat portion 1009 a formed on the periphery of the valve port 1009 by the atmospheric pressure outside the compression storage bag 1002 when the inside of the compression storage bag 1002 becomes negative pressure. , Block the valve port 1009. Thus, the check valve 1006 functions to block the flow of air into the compression storage bag 1002.

The base 1004 has an annular valve seat portion 1009a formed on the upper surface 1004a so as to be continuous with the support rib 1011, and has an annular recess 1014 at the outer peripheral edge of the valve seat portion 1009a at a position lower than the upper surface of the valve seat 1009a.

The height of the ribs 1016A and 1016B is higher than the height of the rib 1017. The high ribs 1016A and 1016B and the low ribs 1017 are alternately arranged in the circumferential direction.

Further, the radial outer ends of the ribs 1016A, 1016B, 1017 are inclined in the same direction, whereby the material of the stored matter gets into the space between the ribs 1016A, 1016B, 1017 when air is sucked by the suction blowout air pump 10. Has the advantage of being able to prevent things more reliably.
An air passage 1018 radially extending from the valve port 1009 is formed between the adjacent ribs 1016A and 1016B and the rib 1017. As shown in FIG. 14, a porous body 1007 covers the lower side of the air passage 1018.

  Of the plurality of ribs 1016A and 1016B having a high height, as shown in FIG. 16, the rib 1016A is continuous with the support rib 1011 in a state of intersecting in a cross shape. Further, the inner ends of the plurality of ribs 1016A intersecting in the cross shape extend radially inward of the inner ends of the remaining ribs 1016B and the inner ends of the ribs 1017, and form the engaged portions 1019. .

A receiving portion 1025 provided at the central portion of the circular dome 1022 receives the central portion 1012 of the check valve 1006. That is, the central portion 1012 of the check valve 1006 is sandwiched between the receiving portion 1025 of the circular dome 1022 of the cover 1005 and the valve holding portion 1010 of the base 1004. The second exhaust port 1024 provided in the circular dome 1022 is disposed at a position facing the conical portion 1013 of the check valve 1006 in the vertical direction.

The porous body 1007 may carry a known mite attractant. As a mite inducer, a pheromone flavor obtained by using, for example, a fruit extract can be used. As a method of holding the mite inducer on the porous body 1007, for example, there is a method of impregnating the porous body with the mite inducer which has been made liquid, and holding the same.

  In the porous body 1007, a central hole 1026 as an insertion hole is formed. On the other hand, the fixture 1008 is inserted into the center hole 1026 of the porous body 1007 to attach the porous body 1007 to the base 1004. Specifically, the fixture 1008 has a mounting cylinder 1027, and the mounting cylinder 1027 has a first end 1027a and a second end 1027b. The first end 1027a of the mounting cylinder 1027 is provided with a slit 1028 as an engaging portion which is detachably engaged with the engaged portion 1019 of the cross-shaped rib 1016A of the base 1004. There is. The outer periphery of the first end 1027a of the mounting cylinder 1027 is fitted to the inner end of the rib 1016B. In addition, a pressing plate 1029 for pressing the porous body 1007 is provided at the second end 1027 b of the mounting cylinder 1027.

  According to the present embodiment, the porous body 1007 has a diameter larger than that of the base 1004 and covers at least the lower side (the lower side and the side at the time of suction shown in FIG. 14) of the ribs 1016A, 1016B, 1017. , The material on the surface of the stored item (for example, a duvet) does not enter 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 air passage 1018 between the ribs 1016A, 1016B, 1017 for communicating the inlet of the valve port 1009 of the base 1004 with the porous body 1007 communicates with the porous body 1007 in a very wide area, Exhaustion through the body 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 compression storage bag 1002, as described above, from the porous body 1007 through the air passage 1018 between the ribs 1016A, 1016B, 1017, the valve port 1009 and the first exhaust port 23 sequentially In addition, although the main path is a path discharged out of the compression storage bag 1002, a path directly leading to the air path 1018 without the porous body 1007 may be present in part.
In addition, the porous body 1007 can be easily attached to the base 1004 by inserting the attachment 1008 into the center hole 1026 as the insertion hole of the porous body 1007. Specifically, the mounting cylinder 1027 of the mounting fixture 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 1027a of the mounting cylinder 1027 is a cross-shaped rib In a state of being engaged with the engaged portion 1019 of 1016 A, the porous body 1007 is pressed by the pressing plate 1029 of the second end 1027 b of the mounting cylinder 1027. Thereby, 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 porous body 1007 can be reliably held.

  In addition, since the engaging portion 1028 is detachably engaged with the cross-shaped rib 1016A, the fixture 1008 can be easily removed from the base 1004. Therefore, the porous body 1007 can be easily attached and detached from the base 1004, and maintenance work such as cleaning of the porous body 1007 can be easily performed. Also, a 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 added to the embodiments described above with respect to the mechanism, the shape, the material, the number, the position, the arrangement, and the like without departing from the scope of the technical idea and object of the present invention. 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, and can rotate with the outer shell portion 20 with respect to the handle portion 30. The switching unit 100 may not be connected to the outer shell 20 and may be connected and fixed to the handle 30. Also in this case, the positional relationship between the drive mechanism 40 and the flow path switching unit 100 becomes the positional relationship of FIG. 12 or FIG. 13 by the circumferential rotation of the outer shell 20 with respect to the handle 30. The flow path switching unit 100 switches the connection destination of the inflow channel of the air flowing into the inlet 84 and the connection destination of the discharge channel of the air guided by the outer shell 20, and sucks the central inlet / outlet. Or it can be in a blowing state.

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

  Also, for example, the time required for suctioning the air in the storage bag is equivalent to that of a canister type vacuum cleaner, is less likely to break down, is small and lightweight, and switching between suction and blowout from the same port may be used. Suction blow-out air pump 10 as what can be done does not need to be equipped with handle part 30. That is, the suction blowout air pump 10 may be configured such that the upper end edge of the outer shell 20 is closed and the outer shell 20 includes the drive mechanism 40.

  Also, for example, the number of switching side standing partition plates 118 may be one. However, when there are a plurality of sheets, it is possible to more reliably block the air on the inflow channel side near the flow channel switching unit 100 and the air on the discharge channel side.

  Also, for example, as shown in FIGS. 17 and 18, the skirt nozzle attachment 150 is formed at an arbitrary tip diameter according to the diameter of the suction valve provided in the optional storage bag B or the compression storage bag 1002. It may be As a result, even with the storage bag B or the compression storage bag 1002 having an arbitrary suction valve, the suction / blowing air pump 10 can suction the air inside the storage bag B reliably and in a short time.
