Electrical air blower
Abstract
An electric air blower includes a housing being composed of two
symmetrical semi-housings. Each semi-housing has multiple feet
formed at a lower side thereof, multiple notches respectively
defined between the feet, multiple air inlets defined at a bottom
plate thereof, a middle plate formed at a middle portion thereof,
an upper plate formed at an upper portion thereof, and multiple air
outlets defined through a top surface thereof. An air impeller is
mounted between the bottom plates and the middle plates of the
semi-housings. A motor is mounted between the middle plates and the
upper plates of the semi-housings. An output axle of the motor
extends downwards for driving the air impeller. A circuit board is
installed in the housing and electrically connected with the motor.
Thus, an inflatable toy fastened on the air blower can be
continuously inflated by the electric air blower to attract
passers-by.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to an electrical air blower,
and more particularly to an electrical air blower for pumping up an
inflatable toy or doll.
[0003] 2. Description of Related Art
[0004] Inflatable toys or dolls are generally pumped up by an
inflator or a pump. The inflated toys should be detached from the
inflator or pump and are used individually. However, air will
gradually leak out from the inflated toys and thus they shrink,
thereby needing to be pumped up again. Thus, the prior art
inflators are very inconvenient for a user.
[0005] Therefore, the invention provides an electric air blower to
mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
[0006] The main objective of the present invention is to provide an
electrical air blower which can continuously blow air into an
inflatable toy.
[0007] Other objectives, advantages and novel features of the
invention will become more apparent from the following detailed
description when taken in conjunction with the accompanying
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0008] FIG. 1 is a perspective view of an electric air blower in
accordance with the invention;
[0009] FIG. 2 is an exploded perspective view of the electric air
blower of FIG. 1; and
[0010] FIG. 3 is an operationally schematic view of the electric
air blower used with an inflatable toy.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0011] With reference to FIGS. 1-2, an electric air blower (10) in
accordance with the present invention has a cylindrical housing
being composed of a first semi-housing (20) and a second
semi-housing (30) attached to the first semi-housing (20) by
fasteners (not numbered). The first semi-housing (20) and the
second semi-housing (30) are symmetrical to each other.
[0012] The first semi-housing (20) has multiple first feet (21)
formed at a lower side thereof and multiple first notches (22)
respectively defined between the first feet (21). The second
semi-housing (30) has multiple second feet (31) formed at a lower
side thereof and multiple second notches (32).
[0013] With reference to FIGS. 1-3, the first semi-housing (20) has
multiple first air inlets (23) defined at a bottom plate (not
numbered) thereof, and the second semi-housing (30) has multiple
second air inlets (33) defined at a bottom plate (not numbered)
thereof.
[0014] A first middle plate (24) is formed at a middle portion of
the first semi-housing (20), and a first upper plate (25) is formed
at an upper portion of the first semi-housing (20). A second middle
plate (34) is formed at a middle portion of the second semi-housing
(30), and a second upper plate (35) is formed at an upper portion
of the second semi-housing (30).
[0015] A first bulb cap (26) is formed at a top surface of the
first semi-housing (20), and a second bulb cap (36) is defined at a
top surface of the second semi-housing (30) and matches the first
bulb cap (26) to form a bulb chamber (not numbered) for installing
a bulb (70) therein. The first bulb cap (26) has multiple first
elongated slots (27) defined therethrough, and the second bulb cap
(36) has multiple second elongated slots (37) defined
therethrough.
[0016] A first semi-groove (28) is transversally defined at an
outer periphery of the first semi-housing (20), and a second
semi-groove (38) is defined at an outer periphery of the second
semi-housing (30) and matches the first semi-groove (28). Multiple
first air outlets (29) are defined through the top surface of the
first semi-housing (20), and multiple second air outlets (39) are
defined through the top surface of the second semi-housing
(30).
[0017] An air impeller (40) is mounted between the bottom plates of
the semi-housings (20, 30) and the middle plates (24, 34). A motor
(50) is mounted between the upper plates (25, 35) and the middle
plates (24, 34), and has an output axle (51) extending downwards to
drive the air impeller (40).
[0018] A circuit board (60) is installed in the first semi-housing
(20) and electrically connected with the motor (50). The bulb (70)
is installed in the bulb chambers being composed of the first bulb
cap (26) and the second bulb cap (36). When the bulb (70) is turned
on, light can pass through the elongated slots (29, 39).
[0019] In use, an inflatable toy (80) with an opening (81) at a
bottom thereof is provided outside the air blower (10). The bottom
of the inflatable toy (80) is fastened by a cord (not shown) in the
grooves (28, 38). Then, when the air blower (10) is actuated, the
air impeller (40) is driven by the motor (50) to rotate, and air
flows through the air inlets (23, 33) into the air blower (10) and
is blown out through the air outlets (29, 39) to inflate the
inflatable toy (80). Thus, the inflatable toy (80) can be
continuously inflated to float in air as long as the electric air
blower (10) is actuated, and can be used as an advertising mark to
attract passers-by.
[0020] Moreover, the bulb (70) can be turned on to use the
inflatable toy (80) at night.
[0021] It is to be understood, however, that even though numerous
characteristics and advantages of the present invention have been
set forth in the foregoing description, together with details of
the structure and function of the invention, the disclosure is
illustrative only, and changes may be made in detail, especially in
matters of shape, size, and arrangement of parts within the
principles of the invention to the full extent indicated by the
broad general meaning of the terms in which the appended claims are
expressed.
