Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a hair dryer, and particularly to the structure of a dustproof cap attached to an outside air intake port of a main body case.

(Prior technology) As a hair dryer, a brush, comb, etc. is attached to the hair dryer, and the main body case is attached to the back of the main body case so that hair can be styled by holding the main body case in the hand and rotating it around its axis. It is known that the power cord is led out from the end (Japanese Patent Application Laid-Open No. 1973
-93154).

(Problem to be solved by the invention) However, in the conventional device described above, the outside air inlet was formed directly around the cord lead-out part of the main body case, so the opening window area of each inlet was limited due to processing and molding. It cannot be made microscopic, but rather large, so it can prevent the intrusion of fingertips and other large foreign objects, but it is not effective in preventing the intrusion of small particles, and especially during use as described above, There was a problem with hair being easily sucked in from the inlet.

As a means to solve this problem, it is conceivable to attach a dustproof cap to the outside air intake port to prevent hair from being sucked in. In this case, an outlet hole for the power cord is formed in the dustproof cap and the power cord is led out from there, but this makes it easier to rotate the main case to curl the hair as described above. , the power cord strongly presses against the periphery of the outlet hole, and due to this pressing force,
This causes problems such as the peripheral edge becoming deformed and damaged, or the dustproof cap falling off unnecessarily from the main body case. Furthermore, if the dust-proof cap becomes clogged with cotton dust etc. during long-term use, the suction efficiency will decrease and abnormal heat generation will occur.

SUMMARY OF THE INVENTION An object of the present invention is to provide a hair dryer equipped with a dustproof cap that is convenient for leading out the power cord.

(Means for Solving the Problems) For this purpose, the present invention provides a hair dryer in which a power cord 5 is led out from an outside air inlet 2 formed in a main body case 1, and a dustproof cap 7 is attached to this outside air inlet 2. is attached. The dustproof cap 7 is formed into an elastic substantially conical shape from an inner circumferential edge 12, an outer circumferential edge 11, and a net 14 formed between these.
The rotary connector 6 provided at the tip of the power cord 5 is inserted into the lead-out hole 8 surrounded by the power cord 5, and the outer peripheral edge 11 side is detachably fitted to the main body case 1. be.

(Function) According to the above configuration, the pressing force F acting on the inner peripheral edge 12 of the outlet hole 8 of the dustproof cap 7 from the rotary connector 6 is transmitted outward, but the dustproof cap 7 has a substantially conical shape. Therefore, this pressing force F is applied to the inner peripheral edge 12
This pressing force F
is absorbed by the net 14, so this pressing force F is transmitted to the outer peripheral edge 11, and the pressing force F is transmitted to the outer peripheral edge 11.
will not fall off from the main body case 1.

(Example) Next, an example of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, 1 is a main body case of the hair dryer, 2 is an outside air intake port formed at the rear end, and 3 and 4 are a motor and a fan housed inside the main body case. 7 is a dustproof cap,
It is detachably attached to the outside air intake port 2. The dustproof cap 7 is made of synthetic resin and has an elastic, substantially conical shape. 11 is its outer peripheral edge, 1
2 is an inner peripheral edge portion, both edge portions 11 and 12 are connected by a radial connecting portion 13, and each portion 11 to
A net 14 is formed in the portion surrounded by 13. Reference numeral 5 denotes a power cord led out from the outside air intake port 2, and 6 is a rotary connector provided at the tip of the power cord. 8 and is rotatably inserted into the hole. 10 is a notch formed from the outlet hole 8 toward the outer periphery;
By expanding the width of 0, the outlet hole 8 can be freely expanded.

15a is a rib provided radially on the outside air intake port 2, 15b is a rib provided annularly on this rib 15a, and both ribs 15a, 15b are connected to the grid body 1.
5. This lattice body 15 can be used to prevent people from accidentally inserting their fingertips into the outside air intake port 2 with the dustproof cap 7 removed and injuring their fingertips due to the fan 4, or allowing large foreign objects to enter the main body case 1 and damaging internal equipment. prevent Note that the rotary connector 6 is attached to the grid body 15 at its tip.

The partially enlarged view of FIG. 1 shows the means for attaching the dustproof cap 7. Reference numeral 21 is a stepped portion formed on the outer circumferential surface 1a of the main body case 1 surrounding the outside air intake port 2. Fitting part 22 in part
is installed protrudingly. Further, a fitting part 23 is provided on the inner circumferential surface of the outer peripheral edge part 11 of the dust-proof cap 7 to protrude from the fitting part 22 and is elastically and removably fitted to the fitting part 22. 22, the dustproof cap 7 is attached to the main body case 1. In this state, by forming the stepped portion 21 in the main body case 1, the outer circumferential surface 1a of the main body case 1 and the outer circumferential surface 11a of the outer circumferential edge portion 11 become substantially flush and continuous surfaces.

By configuring the attachment means for the dustproof cap 7 in this manner, the diameter of the main body case 1 can be utilized to the maximum extent as the diameter of the outside air intake port 2. Furthermore, when holding the body case 1 in your hand and rotating it in order to curl your hair, the power cord 5 may bend, causing the rotation connector 6 to be pushed strongly against the inner peripheral edge 12. However, this pressing force F is dispersed from the inner circumferential edge 12 toward the outer circumferential edge 11, and a highly flexible net 14 is provided between the two parts 11 and 12.
exists, this pressing force F is absorbed by the net 14, and therefore, this pressing force F is transmitted to the outer peripheral edge 11, deforming the outer peripheral edge 11, and preventing it from falling off from the main body case 1. do not have.

In addition, since the dustproof cap 7 has its outer peripheral edge 11 fitted onto the outer peripheral surface 1a of the main body case 1, it is possible to prevent the dustproof cap 7 from reducing the effective suction area of the outside air intake port 2 as much as possible. Surface 1a,
11a is a continuous surface with no steps, so when you hold the main body case 1 in your hand and turn it to style your hair, your hand will not get caught, and since there are no steps, the appearance will be better. Furthermore, since the fitting parts 22 and 23 are located outside the suction passage,
The fitting parts 22 and 23 are not easily clogged with dirt and can always be reliably attached and detached. In addition, when separating the dustproof cap 7 from the main case 1 for cleaning etc., remove it from the outside air intake port 2 and deform it so as to widen the width of the cut groove 10 to open the outlet hole 8. If you expand the power cord 5 through the widened groove 10, the dustproof cap 7
can be completely separated from the main body case 1 and power cord 5. Also, when attaching to the suction port 2, the cut groove 10 may be expanded in the same manner and the power cord 5 may be passed through the cut groove 10.

(Effect of the invention) As explained above, the present invention provides a hair dryer in which the power cord 5 is led out from the outside air intake port 2 formed in the main body case 1, and the dustproof cap 7 is attached to the outside air intake port 2. In addition, the dustproof cap 7 is formed into an elastic substantially conical shape from an inner circumferential edge 12, an outer circumferential edge 11, and a net 14 formed between these.
The rotary connector 6 provided at the tip of the power cord 5 is inserted into the lead-out hole 8 surrounded by the power cord 5, and the outer peripheral edge 11 side is removably fitted to the main body case 1. So, power cord 5
Even if a strong pressing force F acts on the inner peripheral edge 12 of the outlet hole 8 due to bending, this pressing force F will be applied to the inner peripheral edge 12 of the elastic, substantially conical dustproof cap 7.
from the outer peripheral edge portion 11, and both portions 1
Since a highly flexible net 14 exists between 1 and 12, this pressing force F is absorbed by the net 14, and therefore this pressing force F is applied to the outer peripheral edge 11.
As a result, the outer peripheral edge 11 is deformed and does not fall off from the main body case 1. Furthermore, if the net 14 becomes clogged during long-term use, the dustproof cap 7 can be removed from the main body case 1 and cleaned easily.
