Description

[Detailed Description of the Invention] The present invention relates to an improvement of a scum suction type electric razor.

Conventionally, this type of electric razor has a blade wheel rotated by the motor between an inner blade that rotates in sliding contact with the inner surface of the outer blade, and a blade wheel rotated by the motor. It is known that a case is equipped with a filter on the bottom side, and the beard shavings are sucked in by blowing air and collected in the filter.

In such an electric razor, when cleaning the cutting part of the beard, etc., the outer blade body, inner blade body, sink waste guide tube, etc. are removed, and after cleaning is completed, these parts are reinstalled. As for the inner cutter that supports the inner cutter, the protruding blade surface made it difficult to handle, and it was difficult to fit it smoothly onto the motor's drive shaft, making attachment and detachment laborious. .

Therefore, in view of the above-mentioned conventional circumstances, the present invention has been developed so that the inner blade body can be fitted and integrated with the inner periphery of the air blowing guide cylinder, which is detachably attached to the outer periphery of the inner blade body. To provide an electric razor in which handling of the inner cutter body is facilitated by a simple improvement in which the inner cutter body is detachable, and the operation of attaching and detaching the inner cutter body during cleaning etc. is facilitated.

An embodiment of the present invention is shown in FIGS. 1 and 2A below.

The explanation will be based on B.

In FIG. 1, 1 is a main body case, and 2 is the main body case 1.
The outer cutter body is configured at the tip, and 2A is the outer cutter stand that is detachably screwed into the upper front of the main body case 1, and 2B is the outer cutter stand 2.
A curved outer cutter attached to the front surface, 3 is the inner cutter body, 3A is the inner cutter stand, 3B is the inner cutter attached to the front of the inner cutter stand 3A, and its cutting edge is the outer cutter 2B. It is designed to make sliding contact with the inner surface.

Reference numeral 4 denotes an air blowing guide tube, which will be described later, which is disposed on the outer periphery of the inner cutter base 3A, and the large diameter side opening periphery, which is formed in a conical shape and has a conical inner surface embossed on the downstream side of the air blowing side, is the first section of the main body case. It is clamped and fixed between the end and the outer cutter stand 2A.

Reference numeral 5 denotes a blade wheel such as a sirocco fan, which is integrally connected to the inner cutter body 3 by removably fitting the connecting shaft 5A at the center into the connecting hole 3a at the rear of the inner cutter stand 3A.

Reference numeral 6 denotes a ventilation passage provided downstream of the impeller 5, and 7 denotes a filter for collecting hair debris that is detachably installed downstream of the ventilation passage 6, that is, at the lower front of the case body 1.
It consists of a plastic net, etc.

8 is a ventilation hole formed below the filter 7 at the bottom of the main body case 1, and 9 is a drive motor, which is fixedly supported inside the main body case 1 by 10 screws.

The connecting shaft 5A is inserted into the drive shaft 9A of the motor 9 and connected to the impeller 4 and the inner blade 3.

11 is a power plug blade. In the electric razor having the above configuration, in the present invention, a conical surface B that can be brought into close contact with the conical inner circumferential surface A of the air blowing guide cylinder 4 is formed on the outer circumferential surface of the inner cutter body 3 that supports the inner cutter.

That is, in this embodiment, as shown in FIG. 2A, 12 ring-shaped frames are fitted and attached to the rear end of the inner cutter stand 3A, and a conical surface B is formed on the outer peripheral surface of the frames 12. Make it.

In such a configuration, when cleaning the cut portion of the crack, first remove the outer blade 2 and remove the outer blade 2 and the main body case 1.
When the air blow guide cylinder 4 is released from the clamp and is pulled out forward, the inner blade body 3 is attached to the inner circumferential surface A of the air blow guide cylinder 4 as shown in FIG. 2B.
The conical surface B on the outer periphery of the frame 12 is in close contact with the guide tube 4 and the inner cutter body 3, which can be removed from the main body case 1 in a fitted and integrated state.

After cleaning is completed, in order to install the inner blade body 3 into the main body case 1, the guide tube 4 and the inner blade body 3 are fitted and integrated as shown in FIG. Just insert it.

In this case, the connecting hole 3a of the inner blade 3 is always located on the center line of the guide tube 4, and can be smoothly inserted into the connecting shaft 5A connected to the motor 9.

In this way, the inner blade body 3 is fitted and integrated inside the air blowing guide tube 4 during cleaning, etc., and the inner blade body 3 is attached and detached together with the guide tube 4. As a result, the inner blade body 3 can be easily handled. It is not dangerous and can be easily attached and detached during cleaning.

In the electric razor according to the present invention, by simply improving the shape of the inner blade, it is possible to fit and integrate the inner blade inside the air guide tube. The inner cutter body can be handled easily and safely, it can be easily attached to and detached from the main body case, and the cleaning work can be carried out efficiently, which has great practical effects.
