[Detailed Description of the Invention] This invention relates to an improvement of an electric knife sharpener that uses a motor to rotate a grindstone at high speed to sharpen knives, scissors, and other cutlery.

Conventionally, in this type of knife sharpener, the grindstone for sharpening the knife has a sufficiently large mass and has inertia to reduce variations in the polishing condition due to uneven rotation, but after use, the motor must be stopped. Even if you turn the switch off, the grindstone will continue to rotate for a while due to its inertia, which makes it difficult for women and girls, especially those who are not used to grinding, to recognize whether or not the stop operation has been properly performed even after turning off the switch. It made me feel uneasy. Furthermore, if an unexpected situation such as a chipping of a whetstone occurs during sharpening of a knife, it is not possible to immediately stop the grinding process, which is very dangerous.

Therefore, it is conceivable to forcibly stop the grinding wheel by using a friction brake means such as a brake shoe, but this would complicate the structure and
Frictional heat is generated, which adversely affects equipment, and also limits the lifespan of the brake shoe, making it unsuitable for practical use.

In Figures 1 and 2, 1 is a battery power source 2.
4 is a recess formed in the upper wall of the case body 1, in which the motor M and the like are housed.
A grindstone 6 connected to the rotating shaft 5 side so as to be vertically displaceable is disposed in the recess 4 with a portion exposed. The motor M and the grindstone 6 are connected either directly or indirectly through a belt or gear. 7 and 8 are different types of cutlery S such as kitchen knives and scissors,
S', these are grooves for inserting these into the main surface side of the grindstone 6, and these grooves 7 and 8 are covered by a cover 9 disposed opposite to the upper surface of the grindstone 6, which is the main surface side for polishing.
This is constituted by a gap between the upper surface of the main body case 1 and the upper surface of the main body case 1.

Next, the circuit diagram of the knife sharpener is shown in FIG. is formed,
And both ends of the motor M are connected to light emitting diodes 10,
It consists of a protective resistor 11 and a parallel circuit B connected via the switch SW, and the main circuit A and the parallel circuit B connect the switch SW to either of their respective switch contacts p or q. This allows you to choose.

Therefore, when rotating the grindstone 6 during use, connect the switch SW to the switch contact p on the main circuit A side, as shown in Figure 3a.
The motor M and the battery power source 2 are energized, and the motor M rotates at high speed and becomes ready for use. Next, the switch SW is turned off, that is, the switch SW is set to the switch contact q on the parallel circuit B side as shown in Figure 3b.
When the power supply 2 is cut off, the motor M continues to rotate due to the inertia of the grinding wheel 6, but since the motor M acts as a generator, the power generation action of the motor M becomes overloaded. In other words, the electromotive force generated by the rotation of the motor M due to the inertial force of the grindstone 6 acts to brake the motor M, and the grindstone 6 is forcibly stopped. At this time, the light emitting diode 10 connected to the parallel circuit B is activated by the electromotive force generated by the power generation action of the motor M,
Light is emitted until the motor M stops. This light emitting diode 10 is disposed in a partially exposed state on the surface of the main body case 1 so as to be visible from the outside.

Here, in the actual usage condition shown in FIG. 2, insert the knife S into the groove 7, set the cutting edge of the knife S so that it comes into contact with the upper surface side of the grindstone 6, and in that state pull the knife S toward you. The cutting edge is polished over its entire length. After use, or when it becomes necessary to stop the rotation of the grinding wheel 6 due to an unexpected situation such as the grinding wheel 6 being damaged, by operating the switch SW to the OFF state, the motor M will be braked and stopped as described above. Therefore, the grindstone 6 is immediately stopped, and the electromotive force from the motor M, which rotates due to the inertia of the grindstone 6, activates the light emitting diode 10, which is a stop notification means, to notify the user of the precise stop operation. Since the device encourages women and girls to use the device in a safe manner, it does not make women and women who are unaccustomed to use the device feel uneasy, and it also provides excellent safety.
Moreover, in the above embodiment, when the switch SW is in the OFF state, the switch SW is automatically connected to the switch contact q on the parallel circuit B side, and the motor M is always braked because the motor M is always in an overload state. , unnecessary rotation of the grindstone 6 during movement or transportation can be prevented.

As explained above, the present invention provides an electric knife sharpener equipped with a power source, a motor rotated by the power source, and a grindstone transmitted and driven by the motor, in which both ends of the motor M are alerted in parallel to the power source 2. A parallel circuit B is formed which is connected via the means 10, and the above parallel circuit B is formed in conjunction with opening and closing the energization between the power source 2 and the motor M, and at the same time, the parallel circuit B is connected through the means 10 to open and close the energization between the power source 2 and the motor M. Since a switch means is provided to close and open the parallel circuit B in conjunction with the above-mentioned operation, the grinding wheel has excellent stopping performance, and furthermore, it can be confirmed visually or audibly whether the stopping operation is being performed reliably, making it easy to use. To provide a highly safe electric knife sharpener that a person can use with peace of mind.
