Description

Handheld hairdryer with Rotating Drum

This invention comprises of two functions, one being a hair dryer and the other being a rotating drum, which can have different brush headpieces attached to it to dry hair quickly while straightening it and leaving it with a shine.

Background of the Invention

This invention relates to the hair dryer and the concept of a rotating brush. Currently there are many different hairstyles present, more importantly there are many methods of preparing those hairstyles. One of those methods being, straightening your hair by holding a brush and rotating it manually with one of your hands, while occupying the other hand with a hair dryer. In using this method of styling hair, one can get tired easily because this process is very long and extremely exhausting to carry out. You get exhausted because of two reasons, one being holding the hair dryer and moving it with the brush while keeping in close proximity, the other being rotating the brush manually. This invention has two functions, one being a hair dryer, relating to Canadian patent number 1157259, and the other being a rotating drum which can have different headpiece attachments, which is something that has not been produced yet, but its concept is related to Canadian patent number 674675. The hairdryer is a very useful tool but is usually too large and has only one purpose. The purpose of a hair dryer is to dry ones hair by blowing hot air out through a nozzle. A small- motorized fan produces the air usually, and the heat is conducted from heating up spring coils. The commonly available hairdryers have too round of a nozzle in order to release the maximum concentration of heat in one area. An example of such a hairdryer is Canadian patent number 1157259. Hairbrushes come in all different styles, designs, and sizes but still are not efficient to do the job alone of straightening hair. Motorized spinning brushes were created to make the job more efficient and easier. Still due to the motor being placed at the bottom of the device, the sturdiness of such a structure comes into question. Plus there remains the fact that the purchasers of such a device can only use one brush on a single machine. An example of such a device is

Canadian patent number 674675. The hand held hairdryer with spinning drum solves all of these problems. The main purpose of this device is to make straightening hair a one step process. The coils that conduct the heat are placed between the attachable brush headpieces under a protective cover, so that the heat is released directly threw the brush heads to the hair. The slot threw which the heat comes out of is long and narrow and so releases a large concentration of heat. The shape of the slot is a long rectangular type so that the heat is being released to a more preferable and concentrated area. The rotating drum is placed at the top of the device and is capable of spinning in two directions. Once an attachment is attached to the device and secured through the use of the two buttons in the drum, the rotating of the brush can begin to take place with a sturdy structure securing it.

DETAILED DESCRIPTION OF THE INVENTION

In the particularly advantageous embodiment of the invention as illustrated in FIG, 1, this device has a handle 1 that contours conveniently in ones hands. The switch 2 is the one that controls the speed of the fan 28, in FIG. 12, in order to release higher or lower amount of air through the air outlet 10. Switch 3 controls the heat level, hot or warm, and the safety device 31 will primarily be a bi-metallic switch to cut tl e power if the air gets too hot. Switch 4 is the controls for tlie rotating drum allowing the drum to go in either direction, left or right. Switch 4 will be connected to the switch block 30, which can supply power of either polarity to the motor, so the motor can spin in either a forward or reverse direction. The protective cover 6 is put in the inside of handle 1, located at the bottom of handle 1 in order to stop hair from being pulled into the device due to the air flow going into the device. The protective cover 6 also allows the air to flow into the device and is the inlet for the air that will be used by the fan 28 in order to release air from outlet 10. The joining piece 8 is what will hold the handle 1 and cover for coils 9 together. On the very top of FIG. 1 there is the drum piece 14 attached to the drum motor 24, through the use of the hexagonal drum motor attachment piece 32. At the bottom of FIG. 1 there is the electrical cord 5 which will be used to attach the device to its power source. The drum 14 can be seen in FIG. 2, FIG.3, and FIG. 4. FIG. 2 shows the side view of the drum 14, and so it can be seen that there are rectangular openings throughout its sides. The purpose of those openings is to allow the air from tlie outlet to be released into the headpiece attachments. The attachment stabilizers 11 are placed 180° from each other in order to help secure the attachments into place. The securing buttons 12 which are also placed 180° from each other, their purpose is also to provide security for the attachment pieces in order to prevent them from coming off of the device while in operation. The protective cap 13 is made of the same material as the protective cover 6 but its purpose is to allow some air into the drum while preventing any small objects from coming into the device in order to allow some ventilation for the drum motor 24 due to the heat. The hexagonal shape 16 is the attachment indent for the drum motor 24 attachment piece. The air vents 15 can be seen in FIG. 4 are used to allow cool air to come into the drum motor 24. The handle 1 and coil cover 9 attachment piece is 8. It is the piece drawn in FIG. 5, FIG. 6, and FIG. 7. In groove 7 the coil cover 9 will fit into place. In groove 21 the attachment piece will fit in and will rotate within that groove 21. The screw hole 18 will help secure the coil cover with the piece 8 threw the use of a screw. The air holes 22 will let the air flow from the fan to the coil cover 9 where the heat then will exit the device threw the outlet 10. The coil cover 9 can be seen in FIG. 8, FIG. 9, FIG. 10, and FIG. 11. In Fig. 8 a cross- sectional view of the coil cover 9 can be seen. In FIG. 8 the hole for the electrical wiring 17 for the drum motor 24 is shown. The drum motor 24 had to be isolated from the heating coils 25 for safety reasons. Below the hole for the electrical wiring 17 the plastic core expands. It does this so that it can fit more securely into the handle 1 and coil cover 9 attachment piece 8. In FIG. 9 the air outlet 10 can be seen, also in FIG. 9 there is shown the length 20 of the amount of coil cover 9 that will go into the handle coil cover attachment piece 8. FIG. 10 shows that top view of the coil cover 9. In FIG. 10 you can see the hole for the electrical wiring 17, and the drum motor housing space 19. In FIG. 11 the screw hole 18 is shown that will hold the coil cover 9 to the handle coil cover attachment piece 8. The drawings of all of the basic components that make the device operational are shown in FIG. 12. Inside the handle 1 there will be a switch block 30, which will control the direction of the drum motor 24. The switch block 30 will be controlled by switch 4. The fan 28 will have its contours in such a way that it will blow air in the upper direction once attached to the fan motor 27. The fan motor 27 will be held by support pieces 29 that will be part of the handle 1.

There will be two screw holes 26 also in the handle 1, which will secure the handle coil cover 8 to the handle 1 itself. The coil cover 9 will be secured down to the handle coil cover 8 by a screw that will go through the screw hole 18. The coils 25 will be wrapped around the center of the coil cover 9 but not directly. They will be going around some insulating frame. Inside the coil cover 9, against the interior walls, there will be more insulator present in order from keeping the coil cover 9 from getting to hot. There is also a safety device, which is going to be present, primarily a bi-metallic switch 31 that will serve to cut the power if the air gets too hot. The drum motor 24 will be placed in the drum motor housing space 19. On top of the drum motor 24 there will be place a hexagonal attachment piece 32 that will be attached to the drum piece 14 to the drum motor 24. FIG. 13 is how the device will look like when the attachment piece FIG. 18 is put on the groove 7. FIG. 14, 15, 16, 17, 18, and 19 are all drawings of attachments that can be put on top of the device. The device will operate through the use of the switches 2, 3 and 4. Switch 2 controls the fan motor 27, switch 3 controls the coils 25 temperature, and switch 4 controls the direction of the rotating drum. This device cannot be submerged into water at any time. Fingers should not be placed under or on the drum at any time during the rotating of the drum 14.
