Definitions

  • an alternative design is to make limited pressure flaps on the outer part of exhaust holes. When the pressure inside the exhaust holes becomes excessively pressured by a blocked or half-blocked blowing opening, the flaps may be pushed open. When over-loaded, the highly pressured air flow may be released through the exhaust holes.
  • One more step ahead it may be designed to have an adjustable mixing flow air-window at the same time.
  • siphoning effect it may inhale the outer cool air and blow it into the back section of the air blow blades of a hair dryer enabling to adjust the heated air flow temperature by a mixing method.
  • this improvement on a hair dryer supplies one kind of a dryer that has multiple exhaust holes with height differential on the air blowing opening.
  • the exhaust holes perform,leading the air function and mitigate the eclectic heat wire from rapid rising temperature.
  • a sliding cover controls the size of a mixing air flow window on the dryer housing at the back portion of the blowing blades and by applying siphoning effect, it inhales outer air, mixes removing hot air flow inside. By intermingling, the air flow temperature adjustment can be made under the same air flow volume.
  • multiple exhaust holes 2 are made on the rim wall around the blowing opening 10 of a housing 1 of a hair dryer of this invention.
  • the total opening area of these exhaust holes areas must be at least larger than half of the blowing opening 10 area.
  • exhaust holes 2 may be made on the blowing opening 10 cover body that is attached to a hair dryer.
  • the cover body has one of the above stated various structures.
  • the above stated exhaust holes 2 may have limited pressure flaps 3 on the outer housing. While flaps are not pushed by the air flow, the exhaust holes 2 remain covered.
  • the flange is used to fix the limited pressure flap 3 with a twisting spring.
  • the limited pressure flaps 3 as stated above, one step ahead, may be controlled by twisting spring or other mechanical spring plate, enabling the limited pressure flaps to raise to certain degrees and then open completely and automatically.
  • an adjustable window 4 may consist of a snapping plate 41 and a pushing base 42. After it is snapped onto the mixing flow opening 12, the pushing base 42 is located near the pistol-grip, making it easy to push while operating. After the snapping plate 41 is snapped in, its end and the front rim end of the adjustable window 4 have a proper differential. Thus, while exhausting, the reverse flow of the heated air does not in a direct collision with an out-blow, heated flow.
  • an exhaust pipe cap 5 having exhaust windows 52 may be mounted on it.
  • This supplies a complete hair dryer and produce an exhaust function, shown as Figure 4 and Figure 5.
  • the mounting end of this exhaust pipe only a short portion of it, has an outer annular 51 with knurls on it.
  • the outer rim of the blowing opening of a hair dryer are threaded and the inner rim of the exhaust pipe cap 5 are threaded correspondingly.
  • the exhaust pipe cap 5 may be screwed on the end of the blowing opening. It also enables the exhaust windows 52 tow move amount and change covering a blowing opening position. the variations for the uncovered opening area may be gained.
  • This exhaust pipe cap 5 may have multiple open sleeves enabling it to be mounted directly on the complete outer pipe of the blowing opening.
  • the mounting end of the exhaust pipe cap 5, one step ahead, may have multiple angle shaped pipe or multiple angle, arc shape pipe 7.
  • the protruding part of each angle becomes an exhausting hole.
  • the end of the pipe cap 7 is blocked, the air flow is exhausted through the gap of protruding apart of each angel to the outside of the blowing pipe 1.
  • the above mentioned blowing opening of a hair dryer which applies the mounting connection method and exhausting flow function, may have another design.
  • the pipe body of a blowing opening 10 may be a multiple-angel shaped end having uneven waves. As it gradually extends backward, it becomes a complete round, annular pipe.
  • Its exhausting cap may be a complete annular pipe 811.
  • the inner diameter of the annular pipe cap 811 may reduce gradually toward its end. When it is mounted on an uneven waves shaped blowing opening body 10, it caps about 1/2 length of the uneven waves shape. When the annular pipe cap 811 is blocked, the heated air flow may be led out smoothly through the gap created by the indented part of the blowing opening 10.
  • the shaped of this uneven waves blowing opening 10 may have a triangle, square, or more than five angles shaped waves.
  • the improvement of an hair dryer includes at least one set of cuttings 101 at the blowing opening of a hair dryer. From these cuttings, in case the blowing opening is blocked, the heated air flow can be exhausted, as shown in the Figure 13.
  • the side exhaust cuttings 101 are designed, like a traditional hair dryer, to avoid a heating wire from being touched (the extension of a blowing opening).
  • the heated air flow may be exhausted through side cuttings 101. Before it is completely blocked, when the opening begins to be blocked, part of the heated air flow starts to flow out. Thus, it prevents the air flow at the blowing opening from over heating. It avoids blowing over heated air toward an object, such as scorching the hair.
  • At least one set of exhaust holes 142 opening from inside toward outside, in the reverse direction to the air flow blowing, are made.
  • This blow focusing cap 143 has a blowing passage 144 which tapering toward the exhaust mouth.
  • the heated wind at the exhaust mouth can be concentrated and strengthened. It also can slide to move around the column shaped structure 141 that is in parallel to a blowing opening.
  • a blow focusing cap 143 is placed on the exhaust holes 142 of the end section side wall of a paralleled column shaped blowing opening 141 of a hair dryer, it produces unadjusted temperature concentrated wind as shown in the Figure 15.
  • a blow focusing cap 143 is placed on the position allowing exhaust holes 142 to be exposed. If blowing opening is blocked, exhaust holes 142 may induct exhaustion, thus preventing the skin from being hurt by overheated blowing.
  • This design one step ahead, can be designed to have windows 170 allowing the exposure of exhaust holes 142 which are made on a paralleled column 141 where a blow focusing cap 143 and a blowing opening meet as shown in the Figure 17.
  • the windows 170 When the windows 170 are positioned to allow the exhaust holes 142 to be exposed, it provides exhaust function. While on the position to cover up, it provides unadjusted temperature concentrated blowing function. If the cap is taken off, it provides the wide spread blowing function.
  • blow focusing cap 143 may have an additional position fixing annular indented groove 180 as shown in the Figure 18.
  • Several protruding points 181 that fit into the groove are made on the paralleled column shaped blowing opening 141.
