With the volume of filter 110 surface area of dictyosome 110A of having compared suboptimization again,, be used for pouring into storage tank 109 rapidly to cross the liquid that filters so that the higher ability that flows through to be provided.
In this embodiment, shank 128A is than rigidity, and is tubular to provide enhancing and maintenance dictyosome 110A's.For this structure, after perfusion storage tank 109, storage tank 109 is being fixed in spray gun (Fig. 1) before, remove filter 110 at connecting thread lid 115 with before closing hand-hole 112D.Like this, when in use extracting liquid, filter 110 does not disturb caving in of storage tank 109.Aspect other, the class of operation of this embodiment is similar to last embodiment, is therefore understood from above narration meeting.
Revise in the structure (not shown) one, can replace bracing frame 128 with many annular brace ring (not shown) that extend around dictyosome 110A, at axial disconnected position place.These rings provide intensity, keeping the tubular of dictyosome 110A when liquid is added to storage tank 109, but allow filter 110 to cave in storage tank 109 when in use extracting liquid.Like this, with after the liquid perfusion, storage tank 109 can be connected in spray gun, filter 110 is stayed in the appropriate location in the storage tank 109 simultaneously.Perhaps, bracing frame 128 can be formed and allow filter 110 to cave in, and for example shank can be flexible.
Will appreciate that because hand- hole 12D, 112D and supply orifice 12E, 112E branch are opened that from the above narration of typical embodiment liquid can be added to storage tank 9,109, storage tank 9,109 is connected in spray gun 1 simultaneously.For this reason, the normal position of spray gun 1 from its use reversed, so that storage tank 9,109 is configured to lid 12,112 in the top, and any liquid that is used for being retained in the storage tank 9,109 drains into bottom (storage tank 9,109 may extend from extract the state that caves in that liquid caused at injection timing).Can remove threaded cap 15,115 then, add more liquid again, and not have the risk of loss.And then connect lid 15,115, and spray gun 1 is put upside down normal use location to it again, be used for continuing to spray.
Perhaps, storage tank 9,109 can be pulled down from spray gun 1 and stand on the plane surface, lid 12,112 removes threaded cap 15,115 then in the top (state that caves in that storage tank 9,109 may produce from extract liquid between injection period extends) simultaneously, adds liquid again.Fixed cover 15,115 and storage tank 9,109 is connected in spray gun 1 again is used for continuing to spray afterwards.
When finishing injection, can pull down storage tank 9,109 from spray gun 1, can store any paint of staying in the storage tank 9,109 by close supply orifice 12E, 112E with any appropriate configuration temporarily.Storage tank 9,109 can be connected to spray gun 1 then, to use remaining liquid.Perhaps, after closing supply orifice 12E, 112E, storage tank 9,109 can be dropped with filter 10.
Will appreciate that the present invention is not limited to above-described embodiment.
For example, hand-hole and the supply orifice structure of separating allows filter to stay put when storage tank is connected in spray gun and can add liquid for the storage tank that is connected in spray gun.In the lid of the same side of storage tank, hand-hole and supply orifice can be set.Perhaps, hand-hole can be arranged in the sidewall of storage tank or in the diapire, supply orifice is arranged in the lid.
In another structure, lid can be provided be positioned at central authorities, be used to admit the hand-hole of filter and be used for storage tank is fixed in the connector that separates spray gun, that have outlet.Connector removably is connected in lid around hand-hole, lid is transformed into to be connected in spray gun after liquid is joined storage tank.For this structure, can dismantle storage tank from connector, liquid is added to storage tank, and filter is inserted in the inlet simultaneously.Remove filter then and storage tank is connected in connector, be used for storage tank is fixed in spray gun.As previously discussed, lid and container can for good and all be fixed together.Perhaps, lid and container can removably be fixed together.For example, container can form the liner that is used for rigid outer container, and the lasso that is screwed on the outer container by screw thread simultaneously is fixed in liner releasedly with lid.The liquid provisioning component of this type has formed our theme of announcing on July 30th, 1998 of International Patent Application WO 98/32539.
Along with extracting liquid, storage tank can cave in.In this structure, filter can be flexible, so that can cave in storage tank when filter is stayed in the appropriate location.Perhaps, filter can consequently must remove filter than storage tank than rigidity before storage tank is connected in spray gun.
Can supply and have the storage tank of the sky of the filter of an appropriate location within it, so that the user only needs to pull down threaded cap and injected liquid is wanted in perfusion.Perhaps, can supply filter dividually, so that before perfusion fluid, insert in the hand-hole by the end user.
At storage tank is the occasion that can cave in, can supply the empty tank of the shape that caves in, so that reducing to be used for stores and transportation space, the end user extended this storage tank before adding liquid.In this structure, can supplier tank, the appropriate location of filter bits in the storage tank of the state of caving in simultaneously, perhaps filter separates, so that inserted in the hand-hole by the end user.
In another structure, can supply the storage tank that is perfused with liquid in advance.In this structure, can separately supply filter, if, can be inserted into by the end user so that wish in use to add liquid to storage tank.Perhaps, can supply and have the storage tank of the filter in the appropriate location within it, so that when requiring, can add liquid by the end user.
In another structure, storage tank can be a rigidity.For this structure, filter can be flexible or rigidity and can stay in the appropriate location when storage tank is connected in spray gun.Can supply storage tank empty or that be perfused with liquid in advance, filter is fixed in the appropriate location or separately supply simultaneously.For this structure, in liquid delivery system, require a blow vent, to allow in use to extract liquid from storage tank, for example storage tank can be provided with an openable airport when storage tank is connected in spray gun.
For those skilled persons in this field, other modification and improvement will be more tangible.
As can obviously finding out now, the invention provides with being used for the high flow capacity filter that the liquid provisioning component of the spraying equipment of spray gun for example uses.Like this, liquid is filtered when being added to storage tank, to be provided for being sent to the liquid source of supply that filters of crossing of spray gun.
In addition, by the hand-hole that separates with supply orifice is provided, filter can be stayed in the appropriate location when storage tank is connected to spray gun, if so that wish that filling it up with storage tank with liquid again can use this filter.
In addition, by the filter that has flexible dictyosome is provided, filter can be used in along with extracting in the storage tank that liquid can cave in and in the storage tank of rigidity.
Will appreciate that also above-described typical embodiment is used to illustrate broad range of the present invention and various application scenario, can be individually or can use the feature of embodiment in combination with any further feature of identical or different embodiment.
And, though believe above-described and shown in typical embodiment represented the applicant's known best structure at present, will appreciate that the present invention is not limited to this, in the scope of the following stated claims, can make many modifications and improvement.
