Cordless hairdryer
Abstract
A cordless portable hairdryer that is being used with-out a line
cord install to the electricity, using a rechargeable battery
sandwiching in the handset, connected to a multiple speed control
switch, joined to a motor; that turns the fan to blow air. The
device includes a cordless charger. This circuit, charges the
interchangeable battery until the battery is charged, then it
reduces the corrent to a trickle rate. It will completely recharge
a dead battery in several hours, and the device can be left in the
charger indefinitely, also carries a Led as a visual indication of
full charge. The present solution helps a user to easily carry the
device anywhere to be used and the user is not limited to a confine
area, since the present invention carries a re-chargeable battery
with no memory, providing a long lasting life to the battery.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a Cordless Hairdryer, and
more particularly to a manual portable cordless hairdryer without a
connecting line cord.
[0003] 2. Description to the Related Art
[0004] Many designs for hairdryers have been designed in the past.
These designs are used with line cord. None of the designs
available today, however, includes a Cordless Hairdryer without a
line cord connected to the electricity. The present solution helps
a user to easily carry the device anywhere to be used and the user
is not limited to a confine area, since the present invention
carries a re-chargeable battery-no memory.
[0005] Other designs incorporating the closest subject matter
provide for a number of more or less complicated features that fail
to solve the problem in an efficient and economical way. None of
these designs suggest the novel features of the present
invention.
SUMMARY OF THE INVENTION
[0006] It is one of the main objects of the present invention to
provide a manual portable use.
[0007] It is another object of this invention to be used without a
connecting line cord installed to the electricity.
[0008] It is still another object of the present invention to
provide a manual portable cordless hairdryer that blends with the
surroundings with minimal use of available space.
[0009] It is yet another object of this invention to provide such
an assembly that is inexpensive to manufacture and maintain while
retaining its effectiveness.
[0010] It is another object of the present invention to provide a
manual cordless hairdryer that can be operated without utility
power once is charged.
[0011] It is another object of the present invention to provide a
interchangeable battery system, meaning that the user can change
the battery when needed.
[0012] Further objects of the invention will be brought out in the
following part of the specification, wherein detailed description
is for the purpose of fully disclosing the invention without
placing limitation thereon.
BRIEF DESCRIPTION OF THE DRAWINGS
[0013] With the above and other related objects in view, the
invention consists in the details of construction and combination
of parts as will be more fully understood from the following
description, when read in conjuction with the accompanying drawings
in which:
[0014] FIG. 1 is a cross-sectional view of a hairdryer embodying
the present invention.
[0015] FIG. 2 illustrates bottom view of the battery.
[0016] FIG. 3. represents an isometric cross-sectional view of the
hairdryer charger.
[0017] FIG. 4. is a schematic diagram view of the electrical
circuit of the hairdryer.
[0018] FIG. 5. is a schematic diagram view of the electrical
circuit of the battery charger.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0019] This invention relates to a cordless hairdryer which is made
of any suitable plastic material.
[0020] Referring now to the drawings, where the present invention
is generally referred to with numeral 8 and C as a cross-sectional
view where it can be observed that it basically includes a manual
portable cordless hairdryer being used with-out a line cord install
to the electricity, as shown in FIG. 1 using a rechargeable and
interchangeable battery 1 (5 being the bottom), sandwiching in the
handset, connected to a multiple speed control switch 2 connected
to a battery contact 4 (+), and metal contact 4' (-) joined to a
motor 3; that turns the fan, F to blow air.
[0021] The bottom part of the battery, 5 and the contacts 5' (+)
and 5" (-) are reflected in FIG. 2.
[0022] The device includes a cordless charger 12, together with a
plug 14, a transformer 13, a device holder 11, and a battery
rechargeable rest piece 6 as shown in FIG. 3. The charger charges
the battery then it reduces the corrent to a trickle rate. It will
completely recharge the battery once the battery is plugged to
contact 9, and 10 and the device can be left in the charger
indefinitely. Also carries a Led 7, as a visual indication of full
charge. Thereby, the user (s) may easily recharge the battery at
any time, by installing the hairdryer contiguous to the battery
charger.
[0023] Once the present invention is charged, can be easily carried
by the user(s) anywhere to be used, and with-out the inconvenience
and danger of a connecting line cord attached, which can cause
electric shock, whereby the cordless appliance will maintain the
user(s) from a distance of any personal injury and damage, and the
user(s) is not limited to a confine area:
[0024] Referring to FIG. 4, the present invention comprises the
following essential parts: (1) battery, (2) speed control switch,
(3) motor, (L) low speed, (H) high speed, and (R) resistor.
[0025] As shown in FIG. 5. (13) transformer, (R) resistors, (15)
transistor, (7) Diode light emitting (Led), (18) zener diode, (16)
transistor, (17) zener diode.
[0026] The foregoing description conveys the best understanding of
the objectives and advantages of the present invention. Different
embodiments may be made of the inventive concept of this invention.
It is to be understood that all matter disclosed herein is to be
interpreted merely as illustrative, and not in a limiting
