Detailed description of the invention
Fig. 1 schematically shows the toothbrush with handle 1 and head 2, and wherein, head 2 contains one or more cleaning of teeth elements, for example bristle 6 and/or elastomer cleaning element 7.Reservoir 11 is provided for storing flowable mass.Flowable mass is modal is the fluid of liquid form, but also can be other form, for example semisolid, paste or gel.Reservoir 11 can comprise the liquid container 11a that becomes fluid to be communicated with conveyor zones 11b.Capillary channel 14 extends to flowable mass is delivered to at least one outlet 15 from reservoir 11 along the longitudinal direction of toothbrush substantially.
On the one hand, outlet 15 can be positioned on a surface of head 2, and this surface is relative with the surface of containing cleaning of teeth element 6 and 7 substantially.On the other hand, outlet 15 can be positioned at bristle 6 and/or elastomer cleaning element 7.Optionally, multiple outlets can be located on the head surface that contains cleaning of teeth element and the surface relative with this head surface, for example, to carry the different flowable mass that come from the identical flowable mass in common feed source or come from independent feed source.
Passage 14 utilizes capillarity and flowable mass is drawn into outlet 15 from reservoir 11.Outlet 15 can be configured to the non-woven mat, diaphragm or other structure that allow the medium that contains flowable mass to pass through.The example that can be used for the material of outlet comprises porous plastics and other porous material, those that for example describe below with reference to capillary channel 14.
Capillary channel 14 has substantially capillary structure and is generally porous material.The example of applicable material comprises fibrous material, pottery and porous plastics, those that for example can obtain from Porex Technologies (Atlanta, Georgia).An example of fibrous material is can be purchased from Teibow Hanbai Co., the acryhic material that the sign model of Ltd. (Tokyo) is C10010.The mixture of porous material and/or fibrous material can be provided, and it has larger and less distribution capillaceous.Passage can be formed by many little capillaries connected to one another, or is formed as larger single capillary pipeline.
Reservoir 11 can be formed by any applicable material, and can comprise that scope can be from hydrophily variation to hydrophobic reticulated polymer foam.Hydrophobic foam can use in conjunction with non-water base liquid.The Bulpren S90 that the example of reticulated polymer foam has Recticel (Wetteren, Belgium) to manufacture.Bulpren S90 opens chamber polyurethane foam, 90 holes of its average out to per inch based on polyester.Other example that can be used for the material of reservoir 11 comprises pottery and porous plastics.In a preferred embodiment, reservoir can be the commercially available link fibrous structures that comes from Filtrona or Porex, such as but not limited to polypropylene, polyethylene or depend on selected composition and the copolymer of this base polymer within the scope of the hydrophobicity changing.
The limiting examples of spendable capillaries fabricated has been shown in Fig. 4 to Fig. 7.Device for demonstrating capillarity 10 has housing 20 substantially, and housing 20 comprises for the reservoir 11 of store fluid 13 and overflow chamber 25.For example, reservoir 11 can separate by for example separator 21 with overflow chamber 25, or referring below to like that otherwise separating described in Fig. 7.Reservoir 11 can be the integral part of housing 20 or is connected to the individual component on housing.Entrance 22 is allowed air free and flows the overflow chamber 25 of coming in and going out.
Separator 21 can comprise opening 12, and opening 12 seals by capillary channel 14.Passage 14 extends to outlet 15 and directly contacts with capillary storage member 16 from opening 12 substantially.The average capillarity of capillary storage member 16 is less than the average capillarity of passage 14 substantially.Although capillary storage member is arranged to around the periphery of capillary channel 14, capillary storage member needn't be extended around passage all the time.Capillary storage member 16 and passage 14 strict separates and is nonessential.
Capillary channel 14 can be press fit in the opening in handle 1, or as alternative, handle 1 can be coated molded around capillary channel 14.In preferable production process, passage 14 is individually formed and inserts in handle 1.Capillary channel 14 provides air to enter the unique path in the reservoir 11 of other sealing by it substantially.Passage 14 compared with fine, soft fur tubule by flowable mass be passed to outlet 15.Larger capillary allows that air enters in reservoir 11.Generally speaking, air can be at least via in maximum capillary admission passage.
Referring to Fig. 5, for instance, in the time that the interior generation air of reservoir 11 expands, a part of flowable mass 13 in reservoir 11 will be passed in the part that generally there is no flowable mass of capillary storage member 16 via opening 12 and passage 14.In other words, capillary storage member 16 receive too much flowable mass and prevent flowable mass from export 15 or the other parts of utensil leak uncontrollably.In the time that the pressure in reservoir 11 weakens, the too much flowable mass in capillary storage member 16 will be back to reservoir 11 via passage 14.When volume of air in for example temperature fluctuation causes reservoir 11 fluctuates, just can repeat this process.Because the flowable mass being stored in capillary storage member 16 is always back to reservoir 11, therefore capillary storage member is by the capacity that can not be filled in the time existing air to expand.In addition, at least in the region of opening 12, even if passage 14 is wetting constantly by flowable mass, as long as than there is flowable mass in larger storage member 16 capillaries of the largest hole in passage 14, air just can not interrupt flowable mass 13 and is back to reservoir 11.
Although outlet 15 is shown to the element separating with passage 14 in Fig. 1, Fig. 3, Fig. 5 and Fig. 6, will be appreciated that, outlet 15 can alternatively form one with passage 14 as schematically illustrated in Fig. 4 and Fig. 7.In the time that outlet 15 is formed by porous material, its hole will be less than the hole of passage 14 substantially, to guarantee that the flowable mass in passage 14 during distribution will flow to outlet 15.Referring to Fig. 4 and Fig. 6, passage 14 can be configured to so that it extends near the region 19 of reservoir pedestal 18.In the structure of this type, capillary storage member and capillary channel 14 are surrounded by pipe 24 conventionally.Pipe 24 provides the supplementary protection that prevents accidental release.
In the structure shown in Fig. 4, capillary storage member 16 and capillary channel 14 are independent structural detail, and passage 14 extends in base region 19.In the structure shown in Fig. 6, the mixture with the porous material of essential capillary dimensions combination forms overall capillary storage member 16 and passage 14.
In the structure shown in Fig. 5, passage 14 and capillary storage member 16 define the overall structure element being similar to shown in Fig. 6.The rear portion 140 of the passage of one and capillary storage member is tapered, so that it can be accommodated in opening 12.In order to ensure the tiny capillary that has enough transmission flowable mass in opening 12, the combination passage/storage member of this part can be pressed from both sides and pinched together in the mode limiting.Rear portion 140 also can be provided as the individual component being connected in capillary storage member.
For example, as shown in Figure 7, capillary channel 14' can be configured to so that it comprises radially extension, and this part makes reservoir 11 separate with overflow chamber 25.The opening between reservoir 11 and overflow chamber 25 is filled in passage 14' and radially extension.Radially the hole in extension can roughly be similar to the hole in passage 14' and allow that air passes through, but stops flowing of flowable mass.As a result, radially extension can be used for regulating flowing in air admission passage 14'.
