Description

[Detailed Description of the Invention] This invention relates to a reciprocating electric shaver having thin outer cutters.

Generally, in this type of electric shaver, the thin plate-shaped outer blade is housed in a special case and sold separately from the electric shaver itself, but this is not easy to use. It is desired that the electric razor itself hold the above-mentioned replaceable blade.

In this case, the above-mentioned replacement blade does not get in the way during normal use,
Moreover, it is necessary to adopt a structure for holding a replacement outer blade so that it can be easily attached and detached.

By the way, since the electromagnetic coil, charging circuit component, etc. inside the case body of the electric shaver generate heat during use, it is preferable to form a ventilation hole in the body to dissipate the heat.

It is better to make this vent hole as small as possible in order to prevent dust from entering, but since the case of this type of razor is generally molded with resin using a mold, it is necessary to form the vent hole with the micro diameter mentioned above. is difficult to form.

For this reason, it has been proposed to block relatively large ventilation holes with ventilation filters, but in this case, a ventilation filter must be prepared separately, and the work involved in fixing this filter by pasting etc. is accompanied by complexity.

This idea was made in view of the above circumstances, and an opening is formed in the side wall of the case body corresponding to the heat generating part, and the opening is closed with a thin plate-shaped outer blade that is stretched over the top of the body. To provide a convenient reciprocating electric shaver in which the replaceable outer blade can be held in a case body in a state where it does not get in the way during use, and can be used as it is as a ventilation filter.

An embodiment of this invention will be described below with reference to the drawings.

In FIGS. 1 and 2, 1 is a case body, which includes, for example, a handle case 2 and a blade case 3 fitted to the head of the case 2. The blade case 3 has flexibility. A thin plate-shaped outer cutter 4 is stretched.

Inside the handle case 2, an electromagnetic coil 5 for vibrating a vibrating rod (not shown) for reciprocating the inner blade, a battery to be charged 6, and a wiring board 8 are mounted with an element 7 for configuring a charging circuit.
etc. are stored.

An opening 10 is formed in the side wall of the handle case 2 to correspond to the heat generating parts such as the electromagnetic coil 5 and the element 7, and the opening 10 is formed by intersecting the crosspieces 9 vertically and horizontally. , slide grooves 11.11 are formed, respectively.

Reference numeral 12 denotes a guard plate that is fitted into the slide grooves 11, 11, and this plate 12 has a grid-like ventilation window 13 formed in correspondence with the opening 10, and a back plate extending vertically from its rear end. At both ends of the wall portion 12a, engaging claw portions 15 that are engaged with the retaining holes 14 formed in the main body 1 are integrally formed.

Reference numeral 16 denotes a replacement outer cutter prepared as a spare for the thin plate-shaped outer cutter 4, and this replacement outer cutter 16 has mounting ears 17 that also serve as reinforcement, and are arranged in the respective slide grooves 11 as shown in FIG. The inner wall surface 11a of the guard plate 12 and the inner surface 12b of the guard plate 12 fitted into the groove 11 sandwich and hold the guard plate 12, and in this state, the opening 10 is closed with the replaceable outer blade 16.

In this way, the replaceable outer blade 16 is attached to the inner wall 11 of the slide groove 11.
By simply sandwiching the blade 16 with the guard plate 12, the replaceable outer blade 16 can be removably held in the case body 1 without loosening or interfering with the use. The user can replace the outer cutter 4 at any time, making it more convenient to use.

Furthermore, since the opening 10 is closed by the replaceable outer blade 16, the hot air generated by the heat generating parts 5 and 7 inside the case body 1 can be dissipated to the outside through the numerous hair introduction holes 1B of the replaceable outer blade 16. Moreover, since the bristles introduction hole 1B of the outer cutter 16 has a minute diameter as is well known, the replaceable outer cutter 16 acts as a ventilation filter, and therefore prevents dust from entering as much as possible without losing its heat dissipation effect. It can be prevented.

If the replaceable outer blade 16 becomes dirty, it can be removed from the case body 1 and washed with water.

Note that the reason why the crosspiece 9 intersects with the opening 10 is to reliably prevent the replacement blade 16 from falling off when it is forcibly pushed in, but the dimensions of the ventilation window 13 of the guard plate 12 By adjusting the amount, there is no need to provide the above-mentioned crosspiece 9.

Further, the replaceable outer blade 16 may have a different pattern shape of the hair introduction hole 18 from the outer blade 4 stretched on the top of the case body 1 so that it can be used depending on the length of the hair, for example. Furthermore, by adjusting the width of the slide groove 11, it is possible to hold a plurality of sheets of the same type or different types.

As described above, this invention has heat generating parts 5 and 7 of the case body 1.
By closing the opening 10 formed corresponding to the main body 1 with the replacement outer blade 16 of the thin plate-like outer blade 4 stretched over the top of the main body 1, the replacement outer blade 16 can be used as a ventilation filter for the opening 10. It can be used to dissipate the hot air inside the main body, and in particular, because the holes in the replaceable blade 16 are small, it is an efficient filter that can prevent cotton dust and the like from entering from the outside. Moreover, since the filter is made of a metal outer cutter, it is possible to provide a simple reciprocating electric shaver whose outer cutters themselves have high heat dissipation properties and can reliably dissipate hot air within the main body.
