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 from which a power cord is led out.

(Conventional technology) Conventional hair dryers tend to suck in hair from the outside air inlet during use, and troubles due to hair sucking accounted for most of the malfunctions, especially in hair dryers that were used with attached brushes or combs. , its improvement was desired.

For this purpose, a hair dryer has been proposed in which a ventilation plate 16 having a filter function is provided at the outside air intake port 7, as shown in, for example, Japanese Utility Model Application Publication No. 57-54305 (Japanese Utility Model Publication No. 60-24241). ing.

(Problems to be Solved by the Invention) The ventilation plate 16 is detachably attached to the suction port 7 for convenience of cleaning, etc. However, the ventilation plate 16 is in a closed loop shape.
Since the power cord 11 was led out from the through hole 18 formed in the center, the ventilation plate 1
6 can be removed from the intake port 7,
Since the power plug (not shown) attached to the tip of the power cord 11 gets in the way and cannot be removed, there is a problem that the power cord 11 gets in the way and makes it impossible to clean it thoroughly, such as by washing with water. Ta. Note that the ventilation plate 16 is connected to the power cord 11.
In order to be able to completely separate it from the power plug, the inner diameter of the through hole 18 must be made larger than the power plug, which is extremely disadvantageous in terms of design and appearance. 18, the effective area of the filter decreases and the filter function deteriorates, and complete separation is not possible unless the ventilation plate 16 is moved along the long power cord 11 to its end, so it is difficult to attach or remove it. becomes extremely troublesome.

(Means for Solving the Problems) In order to solve the above problems, the present invention includes a dustproof cap that is removably attached to the outside air intake port of the main body case, and a central hole in the center of which the power cord is led out. At the same time, a net is disposed around the central hole, and a groove is formed from the central hole toward the outer periphery, so that the peripheral edge of the central hole can be freely expanded. A dustproof cap constructed in this way can be easily and completely separated from the inlet and power cord by widening the width of the kerf and enlarging the central hole. It can be easily cleaned and replaced if it is severely clogged.

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

In FIG. 1 and FIG. 2, 1 is a cylindrical main body case of the hair dryer, and 2 is the main body case 1.
an outside air intake port formed at the rear end; 3 is a motor;
4 is a fan, 5 is a power cord, and the power cord 5 is led out of the main body case 1 from the inlet 2. 6 is a rotary connector to which the power cord 5 is rotatably connected. Reference numeral 7 denotes a substantially conical dustproof cap made of synthetic resin, and is detachably attached to the suction port 2. A central hole 8 for leading out the power cord 5 is formed in the center of the dustproof cap 7, and a net 9 is stretched around the central hole 8. Reference numeral 10 denotes a notch formed from the central hole 8 toward the outer periphery, and by expanding the width of the notch 10, the central hole 8 can be freely expanded. 11 is a protrusion formed around the dustproof cap 7, and 12 is a groove that fits into the protrusion 11.

Since this dustproof cap 7 is formed as described above, when removing it from the suction port 2, the central hole 8 is expanded by deforming it so as to widen the width of the kerf 10. 10 through the power cord 5. Also, to attach it to the suction port 2, expand the cut groove 10, pass the power cord 5 through it, and insert the protrusion 11 into the groove 1.
2, just push it in to make it fit. In this way, this dustproof cap 7 is connected to the inlet 2 and the power cord 5.
It can be easily removed from and attached to these items.

(Effect of the invention) As described above, the dustproof cap 7 according to the invention has the following features:
A central hole 8 for leading out the power cord 5 is formed in the center thereof, a net 9 is arranged around the central hole 8, and a groove 10 is formed from the central hole 8 toward the outer periphery. , since the central hole 8 can be freely expanded, by widening the kerf 10 and expanding the central hole 8, it can be easily removed from the suction port 2 or the power cord 5, and attached to these. Therefore, the dustproof cap 7 can be completely separated from the power cord 5 and can be cleaned by washing with water or replaced if it is severely clogged.

Claims (1)

[Scope of utility model registration request] In a hair dryer in which a power cord 5 is led out from an outside air intake port 2 formed in a main body case 1, a central hole 8 through which the power cord 5 is led out is formed in the center, and a hole is formed around the central hole 8. A dustproof cap 7 is formed by disposing a net 9 and forming a cut groove 10 from the central hole 8 toward the outer periphery so that the central hole 8 can be freely expanded. A hair dryer characterized by being detachably attached to the mouth 2.
