Description
Technical field
The present invention is relevant to discharging the reservoir bag blow off valve of air in reservoir bag.
Background technology
In general, bedding class, dress material class etc. have many problems when keeping, and they should occupy a large amount of storage areas when keeping; Again can be because of moisture, make to store thing aging, mouldy, produce strange taste and reproduction insect.
In order securely and effectively to take care of well described bedding class and dress material class, people have developed the contractile reservoir bag with vacuum suction.This reservoir bag generally has an opening, and the blow off valve that has exhausr port has been installed on its opening.The suction inlet of dust collecting fan is connected on the exhausr port of described blow off valve, the suction by dust collecting fan, by outside the air exhausting output in reservoir bag, reduces the volume of bedding class and dress material class as possible.
But described method has 2 problems:
1. the suction of dust collecting fan is concentrated the surface of the storage thing that acts on exhausr port below, makes its adsorption at the entrance of exhausr port, makes the Bas Discharged in reservoir bag will take a lot of time;
2. the load of duster motor is very large, has affected the service life of dust collecting fan;
Therefore, in order to prevent the described surface of described storage thing, block the entrance of described exhausr port, in patent documentation 1 (No. 3681379 communique of Japanese Patent (the 20th section, the 21st section, the 29th section, the 30th section of specification sheets)), proposed several flanges are set below blow off valve base, made to form between described flange the scheme of the passage of air; In addition, in this patent documentation 1, also having proposed need not described flange and use the breaker plate method being comprised of sponge and nonwoven fabrics etc. to replace the scheme of the air by-pass passage between described flange;
Other problem is: the skeleton of a corpse sheet that can breed acarid and can have acarid in the beddings such as bed clothes, they are that a kind of allergic reaction is former, make people produce allergy and various diseases.So, for catching acarid, the scheme that has also proposed anti-acarid thin slice in patent documentation 2 (No. 3848842 communique of Japanese Patent) has been equipped with the sticking inducing layer of tool being comprised of acarid attractant and adhesive between the outer lamella of positive and negative 2 layers of this anti-acarid thin slice.
In sum, for preventing that the blow off valve drain pipe overflow pipe obstruction of reservoir bag from having 2 methods: the 1st method is to be undertaken air-breathing by the air by-pass passage between flange; The 2nd method is without the flange below base and replace the air by-pass passage between flange to carry out air-breathing with breaker plate;
But, using the former method, the surface material distribution that stores thing (as bed clothes) easily enters in the air by-pass passage between flange, if described cloth enters, they can block portion of air passage, thereby make the longer time of Bas Dischargedization expense in reservoir bag; And using the latter's method, this patent inventor finds that by actual tests the Bas Discharged in reservoir bag also will change the time.We think: this is because the area of the entrance connect domain of breaker plate and exhausr port is too narrow, the confined relation of extraction flow.
In addition, about the anti-acarid thin slice of patent documentation 2, caught the acarid of being lured by attractant with adhesive, captive acarid is bonded on anti-acarid thin slice, is inescapable.Therefore, with the anti-acarid thin slice of crossing, be disposable, can only lose.Like this, just, violated ecology.
Summary of the invention
The object of this invention is to provide a kind of reservoir bag blow off valve that can carry out at short notice exhaust.Meanwhile, another object of the present invention is to provide a kind of ecological reservoir bag blow off valve that can effectively discharge acarid in reservoir bag that meets.
The present invention can reach object described above.
For discharging the blow off valve for reservoir bag (1) of air in described reservoir bag, be provided in the opening (3) of reservoir bag (2), described blow off valve by the base interosculating (4) and lid (5), between between described base and described lid, can stop air to enter that reverse shutoff valve (6) in reservoir bag and the porous body (7) larger than described base diameter form.Described base has valve port (9); Described lid has the exhausr port (23,24) that can be communicated with cleaner suction nozzle; (4b) upper several flange (16A that radially increase from described valve port that form below described base, 16B, 17), the below that has formed the air passage radially (18) being communicated with described valve port, the described flange of described porous body palpus covering between the described flange adjoining, it is the passage of Bas Discharged in described reservoir bag.The exhaust pathway of the air passage of described porous body is followed successively by: the described air passage between described porous body, described flange, described valve port and described exhausr port, and finally by outside reservoir bag described in Bas Discharged.
According to reservoir bag blow off valve of the present invention, because the diameter of described porous body is larger than described base diameter, and cover the below of described flange; Therefore store the surperficial material for making clothes of thing (as bed clothes), can not enter between flange, make described material for making clothes sealing or do a part of ventilation path between strait flange.And, because the entrance of valve port is connected with porous body, so the region that the air passage between flange is communicated with porous body is very wide.Like this, very well by the exhaust of porous body, at short notice can be infalliblely by outside air exhausting output.
Described porous body is provided with gangs up hole (26), and it is ganged up.And being equipped with mounting tools (8), it can be loaded on described porous body on described base.Described mounting tools can be gone here and there easily to the described centre hole of described porous body, and be easy to described porous body to be contained on described base.
Described connecting part is connected on described flange, and it can be dismantled.
Because described connecting part can load and unload connection on described flange, so can easily described mounting tools be removed from described base.Therefore, can easily pull down porous body, and can be easily to daily attentions such as the porous body removing clean.Meanwhile, with old porous body, also can upgrade easily new porous body.
Described mounting tools comprises gangs up axle (27), connecting portion (28) and binding (29), gangs up axle (27) and have the 1st and the 2nd edge part (27a, 27b), and it went here and there the described centre hole of described porous body; Described the 1st edge part of ganging up axle described in connecting portion (28) is arranged at, is connected on described flange; Described in being arranged at, binding (29) gangs up described the 2nd edge part of axle, fastening described porous body.The described connecting part of ganging up described the 1st edge part of axle described in described mounting tools is attached on described flange, like this, due to the described binding at described described the 2nd edge of ganging up axle fastening described porous body, therefore can easily described porous body be arranged on described base.And the support of porous body is also very steady and sure.
On described porous body, hold acarid attractant, it can lure acarid.Because described porous body is held acarid attractant, therefore there is following advantages.In reservoir bag, store under the state of thing, place certain hour, then draw the air in reservoir bag with dust collecting fan.The acarid of being lured by acarid attractant within the time of placing like this, is concentrated in porous body.At this moment, due to the suction of dust collecting fan, acarid is discharged reservoir bag easily.So it is effectively getting rid of the acarid storing in thing.And after dust collecting fan sucking-off acarid, these acarids can not stayed in porous body.So, as long as acarid attractant continues to have attractant effect, just can Reusability porous body.
In addition, the numeral in the bracket in foregoing the reference marks of composition of counter structure of the embodiment that narrates below, these reference marks are not placed restrictions on the application range of this patent.

Fig. 1 is the cutaway view of an embodiment of the blow off valve 1 of reservoir bag 2 of the present invention; Fig. 2 is the exploded perspective view of blow off valve 1.
Refer to Fig. 1, blow off valve 1 is arranged on the opening 3 of reservoir bag 2, and it is used to discharge the air in reservoir bag 2.Blow off valve 1 is arranged on than the large porous body 7 of base 4 and by porous body 7 by base 4, lid 5 and the reverse shutoff valve 6 between base 4 and lid 5 of the periphery 3a of the inside and outside opening 3 of clamping reservoir bag 2 and the diameter that is covered with as possible the below of base 4 that mounting tools 8 on base 4 forms, and described reverse shutoff valve 6 can stop air to enter in reservoir bag 2 at reservoir bag 2 during in negative pressure.
The elastic body that reverse shutoff valve 6 is comprised of rubber such as silaatics forms, and this reverse shutoff valve 6 has been equipped with the more smooth central portion 12 of being held by valve-supporting portion 10 and the conical portion 13 increasing from central portion 12 downwards.
As shown in Figure 1, the periphery 13a of the conical portion 13 of reverse shutoff valve 6 generally on 4a, has the periphery 9a (being equivalent to valve seat) that is flexibly contacting valve port 9 on base 4.
While reaching negative pressure in reservoir bag 2, because of the barometric pressure outside reservoir bag 2, reverse shutoff valve 6 is strongly pressed on the periphery 9a (being equivalent to valve seat) of valve port 9, by valve port 9 sealings.Like this, reverse shutoff valve 6 has the air of prevention and flows to the function in reservoir bag 2.
As shown in Figures 1 and 2, have annular recess 14 on base 4 on the neighboring of 4a, this annular recess 14 is connecting the annular flange dish 15 that is arranged at lid 5 neighborings, makes base 4 and lid 5 form one.At this moment, between annular recess 14 and annular flange dish 15, clamping the periphery 3a of the opening 3 of reservoir bag 2.
As shown in Figure 3, below base 4, on 4b, be provided with the several flange 16A, the 16B, 17 that centered by valve port 9, radially increase, they form one and emerge downwards.The height of the aspect ratio flange 17 of flange 16A, 16B is high, and highly high flange 16A, 16B and highly low flange 17 are at circumferencial direction alternative arrangement.
In addition, each flange 16A, 16B, 17 radially outward edge tilt to same direction.Its advantage is: when dust collecting fan can more insure when air-breathing, prevent that the cloth that stores thing from entering between flange 16A, 16B, 17.Between the flange 16A, the 16B that are adjoining and flange 17, have the air passage 18 radially increasing from valve port 9, as shown in Figure 1, porous body 7 is covered with the below of described air passage 18.
As shown in Figure 3, the flange 16A in highly high several flange 16A, 16B is connected on described support lugn 11 with crossing condition crisscross.And the inward flange of the described described several flange 16A that intersecting crisscross more inwardly with radial growth, forms the portion 19 that is bonded in side than the inward flange of the inward flange of remaining flange 16B and flange 17.Described being bonded in portion 19, connecting joint-cutting 28, joint-cutting 28 is as the connecting part that the mounting tools 8 of porous body 7 is installed.
As shown in Figure 2, lid 5 has circumferential body portion 20, is arranged in dome cap 22 that the connecting strap radially inwardly stretching out along main part 20 21 at main part 20 centers connecting, is formed on the 1st exhausr port 23 of several arc shapes that the merry-go-round arrangement between main part 20 and dome cap 22 and the 2nd exhausr port 24 that the several circular holes of merry-go-round arrangement on dome cap 22 form.
As shown in Figure 1, dome cap 22 is relative with reverse shutoff valve 6.Holder portion 25 is arranged on the central portion of dome cap 22, holds the central portion 12 of reverse shutoff valve 6.That is to say, the central portion 12 of reverse shutoff valve 6 is sandwiched between the holder portion 25 of dome cap 22 and the valve-supporting portion 10 of base 4 of lid 5.The 2nd exhausr port 24 is arranged on dome cap 22, and its arrangement position is relative with above-below direction with the conical portion 13 of reverse shutoff valve 6.
As shown in Figure 4, the surface that cleaner suction nozzle 30 is placed on lid 5 starts when air-breathing, air-breathing due to the 2nd exhausr port 24 of dome cap 22, and the conical portion 13 of reverse shutoff valve 6 holds the inner face of dome cap 22.Therefore, the 2nd exhausr port 24 has been closed; Meanwhile, by the 1st exhausr port 23, valve port 9 is opened outside reservoir bag 2.
The example of porous body 7 has: have the weaving cotton cloth of foaming body, nonwoven fabrics, pin perforation, reticulate body, porous thin slice of the sponge, resin etc. of many continuous air bubbles etc.Porous body 7 can be with well-known acarid attractant, and acarid attractant can be used the Fei Luomeng spices forming as fruit concentrate.About porous body 7 is had with the method for acarid attractant: allow porous body be immersed in liquid acarid attractant and make porous body contain acarid attractant.
According to embodiments of the invention, the diameter of porous body 7 is greater than the diameter of base 4, and it must be covered with flange 16A, 16B, 17 below when air-breathing (as shown in Figure 4, be covered with below or side).Therefore the surface material distribution that, stores thing (as bed clothes etc.) just can not enter between flange 16A, 16B and 17.So the surface material distribution of described storage thing can not seal or do the air passage 18 between narrow flange 16A, 16B and 17.Meanwhile, because entrance and the porous body 7 of the valve port 9 of base 4 is connected, the air passage 18 between flange 16A, 16B and 17 is connected with porous body 7 with very large region.Therefore air can be discharged by porous body 7 very wellly, and can firmly carry out in a short period of time exhaust.
In sum, as by air from the order successively of the main path of reservoir bag 2 interior discharges being: air first passes through air passage 18, valve port 9 and the 1st exhausr port 23 between porous body 7, flange 16A, 16B, 17, then discharges from reservoir bag 2.But portion of air also can directly be discharged outside reservoir bag by air passage 18 without porous body 7.
In addition, mounting tools 8 is through the centre hole of ganging up hole 26 of porous body 7, therefore can easily porous body 7 be arranged on base 4.Specifically, the installation sleeve of mounting tools 8 (ganging up axle) 27 was gone here and there the centre hole 26 of porous body 7, and joint-cutting 28, as the connecting portion of the 1st edge part 27a of installation sleeve 27, is connecting the portion that is bonded 19 of criss cross flange 16A.Like this, the binding 29 of the 2nd edge part 27b of installation sleeve 27 is fastening porous body 7, so porous body 7 can be arranged on base 4 easily.And, because of binding 29 fastening porous body 7, therefore the setting of porous body 7 is very firm.
It is upper that connecting part 28 is connected to the flange 16A arranging crisscross, and detachable.So mounting tools 8 can remove from base 4 easily.Like this, porous body 7 can be easily from base 4 handling, and people can be easily to daily attentions such as porous body 7 clean.And, with old porous body, can upgrade easily.
At the interior thing that stored of reservoir bag 2, put after certain hour, with dust collecting fan, carry out air-breathing.At this moment, owing to storing thing, placed certain hour in bag, acarid is lured in acarid attractant, and concentrates in porous body 7, and when dust collecting fan carries out air-breathing compression to reservoir bag 2, acarid can be sucked by dust collecting fan.So, can be very effectively acarid from the interior eliminating of reservoir bag 2.And, air-breathing after, acarid can not stayed on porous body 7 yet.Therefore, as long as acarid attractant continues there is attractant effect (about 3-6 month), just can Reusability porous body 7, meet ecology.And, do not use in an embodiment of the present invention that acarid prisoner as narration in patent documentation 2 to catch the adhesive that sheet is used, therefore can reduce production costs.
After bed clothes etc. are placed on to reservoir bag 2, with dust collecting fan, carry out air-breathingly at once, and compress reservoir bag 2.Then, this reservoir bag 2 is placed to certain hour, the acarid in reservoir bag 2 is lured, and be trapped on porous body 7.Then, can be again air-breathing with dust collecting fan, acarid is discharged.
Because mounting tools 8 is demountable, therefore also can remove acarid with following methods.
That is: mounting tools 8 is removed, porous body 7 has just removed from base 4 like this.At this moment, porous body 7 is put into the bed clothes that will be placed in reservoir bag etc. below, crossed certain hour, the acarid in bed clothes can lured and catch to porous body 7 just.Then, with mounting tools 8, again the porous body 7 of having caught above-mentioned acarid is arranged on base 4, then bed clothes is put into reservoir bag 2.At this moment, can use dust collecting fan to carry out reservoir bag 2 air-breathing, compression reservoir bag 2.Therefore, with dust collecting fan, can siphon away the acarid in bed clothes.
The present invention is not limited to the embodiment described in note, also can be with acarid attractant in porous body 7.Meanwhile, in porous body 7, also can contain secondary function agent, as deodorizer, aromatic, dehumidizier, antiseptic and the insect-proof agent that everybody knows, these functional agents at least can contain a kind of.For example in the fabric porous body 7 of nonwoven, can also flood the secondary function agent described at least one.
In addition, can replace mounting tools 8 with protruding connecting portion, it can make porous body 7 on base 4 bodies, connect and dismantle.
About above-described embodiment, between base 4 and lid 5, clip the periphery 3a of the opening 3 of reservoir bag 2.But, being not limited to this form, the 4a above that can the periphery 3a of the opening 3 of reservoir bag 2 be fixed on to base 4 by the method such as deposited is upper, then in the radial direction of opening 3, lid 4 is connected on base 4.
In addition,, within the scope of the claims in the present invention, can carry out many variations.
