Description

[Detailed explanation of the invention] This invention stores the cut shavings all at once in a collection filter that communicates with the cutting chamber, and also prevents the shavings from flowing back into the blade wheel and cutting chamber when the main body is turned upside down. This is about an electric shaver.

For this type of product, various proposals have been made for the treatment of beard dregs, for example, there are products equipped with filters to collect dandruff, but these conventional products No measures were taken to prevent the electric razor from being turned upside down, and even if it was able to reliably collect the beard shavings, it had the disadvantage that the shavings would flow backwards.

This invention aims to provide an electric shaver that solves these conventional problems.

The present invention will be described below with reference to an embodiment shown in the drawings. Reference numeral 1 denotes the main body of an electric shaver, which is composed of a main body case 3 containing a motor 4 and a front case 2 attached to the main body case from the front. There is.

The front case 2 is entirely made of a synthetic resin material, and has a circular window 47 at the center of the front surface and a groove 49 extending downward from the lower circumferential surface of the window 47.

5 is a male threaded portion formed on the outer peripheral surface of the front surface of the front case 2;
8 is a front plate attached to the main body case 3 with screws 6, 8 is a mounting screw for the motor 4, and 9 is a rotating shaft fixed to the output shaft 10 of the motor 4.

The front plate 7 and the inner peripheral surface 48 of the window 47 of the front case 2 and the groove 4
A thin guide path S, which will be described later, is formed between the inner circumferential surface 50 of FIG.

11 is a cutting chamber; 14 is an outer cutter body consisting of a ring-shaped outer cutter stand 13 which is removably screwed onto the male threaded portion 5; and an outer cutter 12 stretched over the center of this outer cutter stand; and 16 is an outer cutter body. An inner cutter stand is detachably attached to the rotating shaft 9 through an engagement hole 17 formed in the center of the back surface, 15 is a plurality of inner cutters attached to this inner cutter stand, 18 is a conical guide tube, This front peripheral edge portion is held between the joint portion of the outer cutter stand 13 and the front case 2.

19 is a blade wheel like a sirocco fan attached to the rotating shaft 9, S is a guide path with an entrance 20 below this blade wheel,
It extends downward from the inlet 20 in a straight line and communicates with the outside via the outlet 21.

Reference numeral 22 denotes a filter case that is detachably attached to the front of the front plate 7 attached to the main body case 3, and has a substantially U-shaped cross section with the top and back sides open, and has many exhaust holes on the bottom. It has 23.

Furthermore, this case includes a pair of sliding protrusion plates 24, 24 and a retaining plate 25, 25 for mounting on the front plate 7 of the main case 3
, fitting holes 26, 26 are provided, respectively.

When the filter case 22 is slid from below to above along the pair of sliding grooves 29 provided on the front plate 7, the filter case 22 is engaged and held by a pair of protrusions 27 and a pair of protrusions 28 formed on the front plate 7. At this time, a sealed hair collection chamber 38 is formed between the front plate 7 and the front plate 7.

30 is a convex strip formed in two long rows in the vertical direction on the inner surface of the filter case 22, and 31 is a convex strip formed on the inner surface of the filter case 22.
A pair of protrusions 32 formed inside the filter case 22
This is a filter that is removably inserted into the interior through the upper opening 33, and includes a filter integral 34 made of a flat square tube-shaped plastic net or the like, a protective frame 35 integrated with the filter, and a pair of guide ribs 36, 36. I am admonishing you.

Reference numeral 37 denotes a flange formed at the upper end of the protective frame 35, which has a ventilation hole 39 in the center and is sized to close the upper opening 33 when installed in the filter case 22.

When the filter 32 formed in this manner is inserted into the filter case 22, the front surface of the protective frame 35 and the back surface of the guide rib 36 of the filter 32 are in sliding contact with the protrusions 30 and 31, respectively, and the flange 37 is Since the filter 32 is regulated by the stopper 40, the filter 32 is always set at a predetermined position, and a predetermined space 41 is formed in the front, rear, right and left sides of the filter unit 34, and the upper end of the filter case 22 is connected to the stage of the front case 2. The portion 51 is pressed against the front plate 7 on the main body case 3 side.

Reference numeral 42 denotes a meandering plate that is detachably inserted into the filter 32. Each inclined surface 52 is provided with a ventilation hole 44 that allows sink waste to pass through in only one direction, and a drawer plate extending along the center line of the meander is provided at the upper end. A handle 45 is formed.

Reference numeral 46 denotes a beard scraping plate integrally formed at the lower end of the meandering plate 42.

Therefore, when the meandering plate 42 is inserted into the filter 32, the tops A, B, C, D, and E of the meandering plate 42 are connected to the filter 32.
It is designed to come into contact with.

In the above configuration, when the motor 4 is now energized and the rotating shaft 9 is rotated, the inner cutter 15 and the impeller 19 rotate integrally, so the hair scraps cut by the outer cutter 12 and the inner cutter 15 are removed. The debris is sucked in the direction of the impeller 19, but since the guide tube 18 has a shape that narrows the passage smoothly as it goes toward the impeller 19, the debris is efficiently sucked into the impeller 1.
The air is forcibly blown out toward the entrance 20 of the guide path S guided to the section 9.

Therefore, the beard debris falls in a straight line along the guide path S due to the sending force given by the impeller 19 and the action of its own gravity, and is accumulated inside the filter 32.

If the razor is accidentally turned upside down for carrying or charging, etc., and if there is no meandering plate 42, the accumulated shavings will flow back into the cutting chamber 11 through the guide path S. This results in an extremely unhygienic drawback in that the particles scatter to the outside via the outer cutter 12.

However, since the meandering plate 42 is installed in this invention,
In normal use, the beard shavings meander as shown by the arrows in FIG. 1 and accumulate in the filter 32 from below. This prevents beard shavings from getting caught on the surface 52 and flowing back.

On the other hand, in order to remove the hair shavings accumulated inside the filter 32, remove the filter case 22 from the main case 3, and pull out the meandering plate 42 from inside the filter 32 by grasping the removal handle 45 formed at its upper end. For example, not only are the tops of the meandering plates 42 in contact with the inner surface of the filter, but also a scraping plate 46 is provided at the lower end, so that most of the debris accumulated inside the filter 32 is removed to the outside together with the meandering plates 42. is discharged, making it extremely easy to clean the beard shavings.

As described above, according to this invention, it is possible to efficiently collect beard shavings into the filter using the rotating impeller, and a meandering plate is provided inside the filter to prevent backflow of shavings. Even if the razor is inadvertently turned upside down, the razor shavings are prevented from scattering outside, and the shavings collected in the filter can be removed by pulling out the meandering plate, making cleaning extremely easy. This makes it possible to provide a sanitary electric shaver.
