Description

  The present invention relates to the treatment of electric razors, particularly antibacterial and scrap metal on blades.

  The electric razor cuts the rivet introduced into the outer blade from the blade hole provided in the outer blade with the outer blade and the inner blade that is in sliding contact with the inner surface of the outer blade, and stores the shavings at the bottom of the inner blade storage chamber It has become.

  And the waste accumulated in the inner blade storage chamber was cleaned with a brush or the like by opening the inner blade storage chamber, or washed with water in a waterproof structure.

  When the sledges are cut, not all swarf enters the inner blade storage chamber, and the amount of swarf scattered is large. In addition, scraps adhere to the inner blade and the outer blade, and the adhered scraps remain even after cleaning, which is a sanitary problem.

  The present invention has been made in view of these points, and an object of the present invention is to provide an electric shaver that eliminates the scattering of swarf and sanitary problems.

Accordingly, the present invention provides a pole on the ground side of the high voltage generation circuit in a body housing where the user grips and the head portion is provided at one end, and connects the other pole of the high voltage generation circuit to the head portion. The high voltage generating circuit is provided in the inner blade housing chamber in which the inner blade is arranged, and is characterized in that a high voltage is applied when the inner blade is driven . In this case, the other pole of the high voltage generation circuit may be an inner blade, or may be disposed at the bottom of the inner blade storage chamber.

  In the present invention, an antibacterial action is generated by an electric field generated by corona discharge to prevent generation of scum and lipids adhering to the inner blade, thereby suppressing the generation of an unpleasant odor, or scouring with a gradient force. Is introduced into the inner blade storage chamber, or the charged sawdust is adsorbed to the electrode, thereby preventing the dust from being scattered. Further, if the blade portion is brought close to the skin, wrinkles are raised by the induction charging phenomenon, and the introduction efficiency of the wrinkle into the blade portion is increased.

  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. In FIG. 3, reference numeral 1 denotes a main body housing incorporating a drive motor, and an inner blade 3 is provided on a driver element 10 protruding from the upper end surface of the main body housing 1. Are connected. The inner blade 3 in which a plurality of blades 30 are arranged is reciprocated by the driver 10.

  The main body housing 1 incorporates a high voltage generating circuit 5, and one pole (ground side) of the high voltage generating circuit 5 is connected to each blade 30 of the inner blade 3. A needle-like discharge electrode 50 that is a pole is raised from the upper end surface of the main body housing 1 (the bottom surface of the inner blade storage chamber), and the upper end is positioned in the vicinity of the inner blade 3. The high voltage generation circuit 5 applies corona discharge between the discharge electrode 50 and the blade 30 of the inner blade 3 by applying a high voltage of about 0.1 kV to 100 kV to the discharge electrode 50, and generates an electric field by the discharge. An antibacterial action is generated to prevent generation of bacteria due to scraps and lipids adhering to the inner blade 3.

  As shown in FIG. 4, the discharge electrode 50 may be one in which the connecting pin 11 that is a connecting engagement portion with the inner blade 3 in the driver 10 is the discharge electrode 50.

  FIG. 5 shows a discharge electrode 50 having a triangular cross section disposed between the blades 30 of the inner blade 3 and the blades 30 connected to the ground. In this case, a gradient force is generated by applying a high voltage of about 0.1 kV to 100 kV between the discharge electrode 50 and the inner blade 3, and the waste between the blades 30 of the inner blade 3 is moved downward. By dropping, scraps are prevented from adhering to the inner blade 3. As shown in FIG. 6, the same action can be obtained even if every other blade 30 in the inner blade 3 is used as the discharge electrode 50 and the other blades 30 are connected to the ground.

  In the example shown in FIG. 7, a rod-shaped discharge electrode 50 is disposed at the center of the arched blade 30 in the inner blade 3. By applying a high voltage of about 0.1 kV to 100 kV between the discharge electrode 50 and the inner blade 3, the chips are ionized by the induction charging phenomenon due to surface discharge, and the remaining chips between the inner blades 3 are removed. By attracting to the discharge electrode 50, adhesion of scraps to the blade 30 of the inner blade 3 is prevented.

  The power supply side of the high voltage generation circuit 5 is connected to the conductive plate 51 disposed on the upper end surface of the main body housing 1 (the bottom of the inner blade storage chamber), and the other electrode on the output side of the high voltage generation circuit 5 is connected to the inner blade 3. FIG. 8 shows the blade 30 connected to form the discharge electrode 50. In this case, a high voltage of about −0.1 kV to −100 kV is applied to the inner blade 3, and the shaved shavings are ionized by the induction charging phenomenon. To be collected. The discharge electrode 50 may be the outer blade 4 held by the outer blade frame 40 as shown in FIG. 9, or may be disposed on the lower surface of the inner blade 3 facing the conductive plate 51 as shown in FIG.

  FIG. 11 shows an inner surface of the outer blade frame 40 provided with a needle-like discharge electrode 50 whose tip is directed to the conductive plate 51. The discharge electrode 50 is approximately 0.1 kV to 100 kV with respect to the conductive plate 51. When a high DC voltage is applied to report a corona discharge, the electric field exerts a force that presses the scrap against the conductive plate 51, thereby preventing the scattering of the scrap.

  As shown in FIG. 12, a corona discharge may be generated by providing a needle-like discharge electrode 50 whose tip is directed to the conductive plate 51 on the lower surface of the inner blade.

  In FIG. 13, the conductive plate 51 disposed on the upper end surface of the main body housing 1 (the bottom surface of the inner blade storage chamber) is divided into two, and one 51 a is connected to one pole of the high voltage generation circuit 5. The other 51b is connected to the other pole, and the conductive plates 51a and 51b are inclined so that the central portions of the conductive plates 51a and 51b are lowest. If a gradient force is generated by applying a DC high voltage of about 0.1 kV to 100 kV between the conductive plates 51a and 51b to cause surface discharge, scraps are collected between the conductive plates 51a and 51b. The dividing direction of the conductive plate 51 is arbitrary, and the number of divisions is not limited to the illustrated example.

  In the example shown in FIG. 14, a planar external discharge plate 52 is disposed in the inner blade storage chamber, and a high voltage of several kV minus is applied to the outer discharge plate 52 and negative to the inner blade 3. Since dust is attracted to the positive external discharge plate 52 by the dust collection action of induction charging, it is possible to prevent the dust from being scattered and adhering to the inner blade 3.

  The negative side of the high voltage generating circuit 5 may be connected to the outer blade 4 as shown in FIG. 15, or may be connected to the conductive plate 51 at the bottom of the inner blade storage chamber as shown in FIG. In any case, since the waste is adsorbed to the external discharge plate 52, it prevents the attachment of the waste to the outer blade 4 and the scattering of the waste, and prevents the waste from spreading on the conductive plate 51. be able to. The negative side of the high voltage generation circuit 5 may be connected to all of the inner blade 3, the outer blade 4, and the conductive plate 51, or the connection may be switched.

  An example in which one pole (ground side) of the high voltage generation circuit 5 is connected to at least a part of the main body housing 1 and the other pole is connected to the inner blade 3 is shown in FIGS. Since the main body housing 1 is where the user grips when shaving, the user's body is at the same potential as the ground of the high voltage generation circuit 5. For this reason, if a DC high voltage of about 0.1 kV to 100 kV is applied to the inner blade 3, the user's body is in a state where a high voltage is applied between the inner blade 3 and the body.

  Therefore, when the blade portion is brought close to the skin in order to shave the eyelid, an induction charging phenomenon occurs between the inner blade 3 and the eyelid is pulled toward the inner blade 3. For this reason, the wrinkle can also be easily introduced into the blade portion, and there is no shave residue. In addition, the surface of the inner blade 3 is insulated to prevent a short circuit due to contact with the skin.

  The other pole of the high voltage generating circuit 5 having one pole (ground side) connected to the main body housing 1 is connected to the outer blade 4 whose surface is insulated as shown in FIGS. 17 and 18, or as shown in FIG. In this way, the outer cutter frame 40 may be connected in the vicinity of the outer cutter 4. As shown in FIG. 18, since the wrinkles are raised by the induction charging phenomenon, the efficiency of introducing the wrinkles into the blade portion is increased. When the discharge electrode 50 is installed in the vicinity of the outer blade 4, the insulation treatment is easier than when the outer blade 4 is used as the discharge electrode 50.

  Even if the other pole of the high voltage generating circuit 5 having one pole (ground side) connected to the main body housing 1 is connected to the conductive plate 51 located at the bottom of the inner blade storage chamber as shown in FIG. In addition, since the shaved shavings are attracted to the conductive plate 51 side by an induction charging phenomenon, a dust collecting effect can also be obtained.

  In the electric razor provided with the trimmer unit 6, as shown in FIG. 21, the power supply side of the high voltage generation circuit 5 is connected to the outer blade 4, and the other pole is connected to the trimmer unit 6 through the high voltage generation circuit 5, When a DC high voltage of about −0.1 kV to −100 kV is applied to the trimmer portion 6 with respect to the outer blade 4, the shaved shavings are ionized by the induction charging phenomenon and drawn toward the trimmer portion 6 side. Therefore, the scraps that have not entered the outer blade 4 are attracted to the trimmer part 6 without being scattered. Therefore, if the dust collecting part 60 is provided in the trimmer part 6, You can collect scraps.

  Instead of connecting the power supply side to the outer blade 4, it may be connected to the inner blade 3 as shown in FIG. 22, and further to the conductive plate 51 arranged at the bottom of the inner blade storage chamber as shown in FIG. You may connect.

  By the way, the on / off of the high voltage generating circuit 5 may be performed simultaneously by an on / off switch 7 for the motor M for driving the inner blade 3, as shown in FIG. When the main housing 1 is openable and closable, a switch 8 that interlocks with the opening and closing of the outer blade frame 40 is provided so that the high voltage generating circuit 5 is turned on and off by the switch 8 as shown in FIG. It is good to keep. A high voltage is generated only when the outer blade frame 40 is closed. Of course, the switch 7 and the switch 8 may be connected to the high voltage generation circuit 5 in series.

  FIG. 26 shows another example. The discharge electrode 50 is provided with a needle-like member 50 a with the tip directed to the conductive plate 51 and a needle-like member 50 b facing the opposite direction to the conductive plate 51, and the high-voltage generating circuit 5 has the conductive plate 51 and In addition to connecting the discharge electrodes 50a and 50b, switches 7a and 7b linked to the switch 7 are provided between the high voltage generation circuit 5 and the discharge electrodes 50a and 50b. When the switch 7 is on, the switch 7a Is closed and a high voltage is applied between the discharge electrode 50a and the conductive plate 51 to cause corona discharge, and the waste is pressed against the conductive plate 51. When the switch 7 is off, the switch 7b is closed and the discharge electrode 50b A high voltage is applied between the conductive plate 51 and the conductive plate 51 so that an antibacterial action is generated by an electric field generated by corona discharge.
