Definitions

  • the present invention relates to a forced flow-guiding device having perforated mesh surface branched guiding tubes which is a perforated mesh-like, flexible, flat surface structure having a set of single or double faces, a set of hollow guiding manifolds being disposed on one surface or between sandwiched layers.
  • the guiding manifolds are provided with a plurality of fine holes, and a fluid pump is disposed on one end of the main tube such that fluid of suitable pressure is delivered into the guiding manifolds and flows uniformly out from the perforated structure enabling the surface of the object contacting therewith to perform necessary exchanges of physical and chemical properties between said object and fluid.
  • a coping measure taken by workers of this type is to place a flat mattress with a thickness of interstices between the body and the chair, thereby to obtain limited gaps, thus reducing the blocked area.
  • gaps are discontinuous and the fluid (air) is not forced driven, only insignificant comforting effect can be obtained by air flowing through the region.
  • the present invention is to provide effective fluid exchange in a blocked area by means of a perforated mesh-like surface with a set of hollow guiding manifolds disposed thereon, the manifolds being distributed all over the mesh-like surface and provided with a suitable number of fine holes, and a fluid being forced introduced into the hollow guiding manifolds and flowing uniformly out from the mesh-like surface by a fluid pump.
  • the primary object of the present invention is to provide forced fluid exchange in the blocked area created between two relatively contacting objects such that desired physical or chemical effects can be obtained on the contact surface.
  • the forced flow guiding device having perforated mesh surface branched guiding tubes of the present invention consists essentially of a perforated mesh-like, flat surface object 1 having a set of single or double faces, a branched guiding tubular object 2 and a fluid pump 24.
  • the perforated mesh-like flat surface object 1 and branched guiding tubular object 2 are flat and are flexible structures joined together in a flat stacking manner.
  • a drain tube 26 extends from the main tube 22 of the branched guiding tubular object 2 with the fluid pump 24 connected at an appropriate length.
  • the branched guiding tubular object 2 is a flat surface object having flow guiding manifolds in tubular distribution thereon, comprising the main tube 22 as its trunk.
  • the trunk has provided thereon a plurality of branch tubes 23 uniformly distributed over its planar extent, a plurality of fine holes 25 which penetrate through the tube wall and are provided on the surface of the main tube 22 or on the branch tubes 23 facing the perforated mesh-like flat surface object 1.
  • a support structure 21 (arranged as post shaped bodies) of the same height as the main tube 22 and branch tubes 23 is provided in the space between individual branch tubes 23 of the branched guiding tubes such that the joined perforated mesh-like flat surface object 1 has a junction surface of equal height and uniform support.
  • the main tube 22 will gradually change (decrease) its area of cross section in the direction of the end because of distribution of the branch tubes 23 to accommodate the fluid flow and pressure therein.
  • the branched guiding tubular object 2 produces significant pressure difference between the fluid pressures at the inlet (the fluid pump) and the fine holes 25 such that the fluid will flow due the pressure and will flow out uniformly at the fine holes.
  • the fluid pump is provided for supplying suitable fluid pressure in the main and branch tubes so as to overcome the resistance to flow in and out the tubes.
  • One of the embodiments of application for the above structure includes a chair mattress 3 as shown in Fig. 2.
  • Said chair mattress has two sets of perforated mesh-like flat surface objects 1 joined to a branched guiding tubular object 2 serving as a mattress for the chair seat and back, respectively, both being connected by a flexible tube 31 between the main tubes 22, wherein a fluid pump 24 is provided at a suitable position on one end of each of the main tubes.
  • Said fluid pump provides blowing effect for air to blow in from the main tube 22 and to blow out through the perforated mesh-like flat surface objects 1 from individual fine holes 25.
  • Fig. 3 there is shown another embodiment for application of the invention.
  • the perforated mesh-like flat surface object 1 and the branched guiding tubular object 2 are fitted directly inside a chair and at the bottom, and fine holes 25 are provided such that pressurized air produced by the fluid pump can flow out from the fine holes 25 through the main tube 22 and the branch tubes 23.
  • the air blown out will pass through the soft, fine textured chair mattress and flow out uniformly from the surface of the chair.
  • the fluid pump can be connected to a cool air outlet for air of low temperature to flow out from the chair surface, thereby to relieve the suffering due to the legs and the back being pressed against the chair surface for a long time.
  • the fine holes could be modified as showed in Fig. 5 and Fig. 6.
  • a micro-valve 27 is inserted in the fine hole 25 with a micro-spring 28 to supply a suitable supporting force to close fine hole 25 when no object contacting force presses micro-valve 27 inward, and to open fine hole 25 when micro-valve 27 is pressed inward by the object contacting force.
  • the branched guiding tubular object 2 of the present invention which includes a plurality of branch tubes 23, the main tube 2, and the fluid pump 24, can be arranged as a pair of two sets.
  • Each single branch tube 23 of a set is inserted between other branch tubes 23 of another set, and the tubes are placed together one by one of each set to form a layer which is covered by the perforated mesh surface 1.
  • One pump functions to increase the pressure of the fluid in the end of the main tube of a set, and the other one to decrease the pressure of the fluid in the end of the main tube of another set. Thereby the physical and chemical property exchanges between said object and fluid of the blocking region can be improved.
  • the fluid in the branched guiding tubular object 2 of present invention is supplied at a proper difference of pressure between their two ends, from the end of main tube to the fine hole of the branch tube, by some certain physical and chemical circumstances.
  • the fluid pump 24 can be omitted in the present invention by such certain environment.
  • FIG. 4 shows still another embodiment for application of the invention.
  • a fractured limb 4 is shown fixed for treatment by wrapping with a plaster 41.
  • the forced flow-guiding device has perforated mesh surface branched guiding tubes which are provided between the plaster 41 and the limb 4 such that the surface of the perforated mesh-like flat surface object 1 contacts the skin of the limb, the branched guiding tubular object 2 being wrapped around the limb, and then fixed by the plaster or a bandage.
  • a drain tube 26 extends from the end of the main tube to be connected to a fluid pump 24 for fluid to flow over the surface of the limb, thus providing a dry and cool effect.
  • a solution for surface soaking end coating treatment can be injected, thereby to perform the necessary cleaning or attachment, thus improving the surface condition in the affected area by the uniform flow of fluid.
  • an electric heating device and a selection switch can be fitted to the fluid pump 24 to provide another type of quilted cover, pillow, chair or bed mattress which supplies warm fluid or for other uses where a warming effect is required.
  • the present invention can be used for the garments or the protective clothing for sports, for example for use on the inside of a raincoat when the present invention can be used as a forced fresh air flow pad to push the outside fresh air to follow the guiding tubes into the raincoat, and to remove the warm and sweat laden air from the surface of the body, thereby preventing an uncomfortable feeling from the high humidity and temperature caused by blocking a region of the surface of the body which is covered by the raincoat.
  • Another example is a use in sports, such as in football, baseball, or other kind of sports, etc., for wearing the protector for a long time during competitions. The same reason applies namely that it is very uncomfortable due to the high humidity and temperature.
  • protective clothing such as a helmet, chest protector and shoulder pad, etc. they can be made to function in the same manner as the raincoat described above.
  • Another embodiment of the present invention is for use in a storage operation.
  • the invention can supply forced fresh air flow to laminated constructions of a piled up stack, as each layer of merchandise has the forced air flow coming in from outside to adjust the humidity and temperature of the contacting blocking surface to prevent deterioration of the merchandise due to bad storage environments.
  • Commercial benefits can thus result from improving the conditions of storage.
  • the present invention can offer an effective solution for heat conducting in these operations.
  • the traditional steamer can be replaced by putting the present invention into a closed space.
  • the processing speed can be improved and a uniform result can be obtained in each layer.
  • the present invention can provide a forced fluid flow, in the operation of a chemical reaction, for solid objects piled up layer by layer with the fluid surrounding the objects to effect a chemical reaction. Between the layers, forced fluid improves the speed of the chemical reaction and achieves a better and more uniform result.
  • more than one set of the branched guiding tubular object 2 may be arranged together with each one branch being separated apart from and independent of the others. By putting the branched tubes together one by one to another set, the fluid in each tubular is mixed uniformly and is restricted to the area of the blocking region.
  • the present invention aims at forcing fluid to be guided through branched guiding tubes into which a fluid having pressure difference is supplied by a fluid pump.
  • the fluid flows out from the fine holes, the planar fluid effect provided by the perforated mesh-like flat surface object being applied to chairs, bed mattresses, fractured limbs or other surfaces requiring exchange of physical or chemical properties with fluid, all giving good results.
