Abstract
An attachment for a handheld dryer includes a shell and a dryer barrel-receiving portion. A first passage is defined between the shell and the dryer and terminates in a shell inlet defined between the shell and the dryer barrel. The present attachment may be useful to increase volumetric flow and/or velocity of flow from a handheld dryer.
Claims22
An attachment for a handheld dryer of the type that has a barrel through which air flows, the attachment comprising:
- a shell at least partially coextensive with the barrel, a passage being defined between said shell and the barrel, an inlet being defined between said shell and the barrel, said passage communicating with said inlet;
- and,
- at least one barrel-receiving member linked to said shell and operative to attach said shell to the barrel, and wherein the attachment when installed on the dryer causes the motor RPM to increase by less than about 1% and increases volumetric air flow from the dryer by at least about 30% as compared to the dryer without the attachment.
An attachment for a handheld hairdryer of the type that has a barrel for dire ting an air flow through a barrel outlet, the barrel outlet having an area, the attachment comprising:
- a generally tubular shell having at least one fin as a barrel receiving member configured to removably attach said shell to a portion of the dryer barrel, said shell being at least partially coextensive with the barrel, said shell having an inlet larger in area than the barrel outlet area, said shell having an unobstructed outlet with an area smaller than said shell inlet area;
- a generally cylindrical nozzle contained in said shell, said at least one barrel receiving member configured for positioning the barrel outlet adjacent to said nozzle;
- a first passage defined between said nozzle and said shell;
- a second passage defined between said shell and the barrel and terminating at said shell inlet, said second passage communicating with said first passage, said first and second passages having a combined length of at least about 1 inch;
- and
- a mixing region defined within said shell downstream of said nozzle, said mixing region communicating with said first and second passages and said shell inlet, said mixing region having a length of at least about 1 inch.
An attachment for a dryer with a barrel, the attachment comprising:
- a generally cylindrical nozzle configured for engaging the barrel of the dryer;
- a shell at least partially coextensive with said nozzle;
- a mixing region defined within said shell and downstream of said nozzle;
- and,
- at least one passage defined between said nozzle and said shell and terminating in said mixing region;
- said passage is generally tapered from said passage inlet to said mixing region and has a substantially flared inlet at least partially defined by said shell;
- and
- a plurality of spaced apart elongated fins linked to said shell and operative to attach said shell to the barrel, and wherein said plurality of spaced apart elongated fins are configured for frictionally receiving the barrel as the only fastening structure for securing said shell to the barrel.
