Description

Blower handle {A blower handle}

The present invention relates to a blower handle, and more particularly to a blower handle to facilitate the switch assembly during the assembly and use of the wiring during the manufacture of the blower, and to solve the switch breakage caused by the packaging or external contact of the finished product.

The blower 1 as shown in FIG. 1 is a blower in which a motor M for driving a fan F is mounted by a bracket B inside a cylindrical drum 3 having a handle 7 upward. It is mainly used for pipe blowing to inhale turbid air and gas generated in underground construction sites, sewers or closed working spaces that require the exhausting of toxic gases and to discharge it through the pipe or to supply fresh air. .

By the way, the above-mentioned conventional blower had the following problems.

First, as shown in FIG. 1, since the power switch 9 is installed on the side of the base 5 mounted below the drum 3, the user bends his back a lot while the switch 9 is operated. There is discomfort.

Second, when assembling the blower, it is necessary to put condenser parts and peripheral wiring to increase the maneuverability in the internal space of the base 5, and in this process, the base 5 is turned upside down to work. In addition to this inconvenience, there is a high possibility that a scratch is generated on the handle 7 or the upper portion of the drum 3 around the handle.

Third, the switch 9 exposed to the outside of the base 5 under the drum 3 is damaged due to the use environment of the blower which is frequently used in the construction site, and is damaged by the surrounding objects during transportation or use. In some cases, the switch 9 was damaged during logistical operation, resulting in malfunction.

The present invention devised to solve these various problems is easy to process the assembly of the condenser and wiring in the manufacture of the blower, the power switch operation is convenient in use, and can be generated by the packaging or contact with the outside of the finished blower product. It aims to provide a new blower handle that can solve the problem of breakage of the power switch.

Blower handle of the present invention for achieving the above object,

It has a condenser accommodating space and a wiring accommodating space therein, and a power switch connected to the motor and wired on one side of the handle portion is mounted.

The power switch is positioned separately from the portion of the user's hand by a restricting jaw formed on one side of the ruler, so that the power switch does not interfere with the ruled hand when carrying the blower.

The blower handle of the present invention configured as described above simplifies the operation of the power switch, and also eliminates the possibility of damage to the power switch due to contact with the outside during transport or use of the blower, and improves the workability of power supply assembly of the blower. This provides an advantage.

Hereinafter, the present invention will be described as a preferred embodiment based on the accompanying drawings.

2 is an assembled perspective view of the blower to which the handle of the present invention is applied, and FIG. 3 is an exploded perspective view of the blower to which the handle of the present invention is applied, and FIG. 4 is a bottom perspective view of the blower of the present invention. For reference, in describing the present invention, the same reference numerals will be given to the same parts of the blower body as in the prior art.

Blower handle 70 of the present invention is provided with side bodies (72, 73) formed with a threaded through hole 74 for screwing the drum (3) to both sides of the hanging portion (71), the side body (72, Inside the capacitor 73, the accommodation spaces 72a and 73a of the capacitor C and the wiring W are formed.

In addition, the side body 73 formed at one end of the handle portion 71 of the handle 70 is mounted with a power switch 79 wired with the motor M in the longitudinal direction of the handle portion 71 to protrude outward. Not located.

The power switch 79 is positioned and separated from the portion which grips the user's hand by a restricting jaw 75 formed to be biased to one side on the lower surface of the barrier portion 71 to hold the barrier portion 71 when the blower is transported. It is a structure to prevent the user's hand from hitting and interfering.

In addition, the upper surface of the hanging portion 71 has a structure in which the upper portion opened and opened is fastened to the handle body 1 and the screw SC by the cover 82, and when the cover 82 is removed, both side bodies ( A space 78 is formed to interconnect the internal spaces 72a and 73a between the 72 and 73, and the beads 77 are formed in the center of the space 78 in the longitudinal direction of the hanging portion 71. have. The bead 77 increases the reinforcing force corresponding to the total weight of the blower when the blower is mounted, and also secures a seat for forming the screw fastener 77a for coupling the cover 82.

In FIG. 3, reference numeral 76 denotes a small hole formed to prevent shrinkage of a thick portion during injection molding of the handle 70 body.

The blower handle 70 configured as described above has more space in the inner space 72a of the opposite side body 72a than the one side body inner space 73a in which the power switch 79 is installed at the time of wiring (W). Place the capacitor (C) here.

Then, the wiring W is connected from the condenser C to the power switch 79 through the inner spaces 72a and 72b of the lug portion 71 and is connected to the fan driving motor M mounted inside the drum 3. (W) Connect and assemble.

The power switch 79 is inserted into the switch body 79a into the side body 73a and through the groove 73b formed in the side body 73a so that the knob is located outside, and then tighten the side body by tightening with a nut NU. And (73).

By employing the blower handle 70 of the present invention described above, the user can easily check the on, off operation operation and operation state of the power switch 79 without bending the waist or lifting the blower.

In addition, the user can turn off or turn on the power switch 79 even while the user grabs the blower handle 70 and moves the position of the blower, so that various works are performed in an underground construction site, a closed work space that requires the exhaust of toxic gas or the like. Reduce the time spent on

In addition, the condenser (C) and the wiring (W) can be put together in a normal state in which the base (5) is positioned downward, without working in a state of inverting the blower as in the prior art during assembly work. Likewise, there is no fear that scratches may occur on the handle 70 or the upper portion of the drum 3 around the handle.

In addition, when the blower handle 70 of the present invention is adopted, the power switch 79 may be damaged or damaged due to pressure on the surrounding objects during transport or use of the blower, or under pressure during product packaging or logistics operation. There is an effect that can prevent.
