Description

  The present invention relates to a hair razor used in a barber shop or a beauty salon.

  When a woman's long hair is mainly prepared in a beauty salon, a method called leather cut may be used. Leather cut is literally a method of cutting hair using “Razor”, and is used for the purpose of reducing the sense of volume by tapering the tip of the hair and directing movement and lightness. The hair-shaving razor used for leather cutting in a beauty salon has a structure generally shown in FIG. 4 and has a cutting tool 54 for cutting the hair, a guard 53 for holding the cutting tool 54 in between, and a guard 53 for inserting the guard 53. It is comprised from the main body 51 etc. provided with the holder 52 etc., and grips the grip part 55 formed in the main body 51 at the time of use, and performs cutting operation | work by making a blade edge | tip contact a head hair.

  As shown in FIG. 4, the cutting tool 54 has a rectangular shape, a sharp cutting edge is formed on one long side, and the guard 53 has a structure in which a thin plate is bent about 180 degrees near the center, and the cutting tool 54 is sandwiched and held inside. it can. When the cutting tool 54 is sandwiched between the guards 53, the cutting edge is projected from the end of the guard 53. However, a wavy groove 56 is machined at the end of the guard 53 to ensure safety. For this reason, when the cutting tool 54 is accommodated in the guard 53, the blade tip does not protrude outside when the blade tip is positioned lower than the top of the groove 56. Therefore, even when a finger or the like approaches the blade tip, the guard 53 is touched before touching the blade tip. Therefore, accidents such as injury can be prevented. However, since a thing with a small cross-sectional area such as hair enters the groove 56, it is cut by touching the blade edge. By changing the size and interval of the grooves 56 formed in the guard 53, the amount of hair that is cut at a time can be adjusted, and can be selectively used according to the situation.

  Leather cut cuts the hair with a razor, so if the contact angle with the cutting tool is not appropriate, the cutting surface may become sharp or the tip of the hair may become needle-like. In addition to problems such as jumping up, the hair acting on the hair is torn off by the force acting at the time of cutting, and this tends to cause split ends. In addition, when cutting leather, it is necessary to have a pre-process to soften the hair with moisture, so the hairstyle changed from its natural state, and after drying with a drier etc., it became a strange hairstyle You may notice.

  When performing a leather cut, a large amount of hair is cut at one time in the initial stage, but it is necessary to cut it little by little while considering the style in the finishing stage. In addition, there are a portion where there is no problem even if a large amount is cut at a time and a portion which should be cut carefully from the beginning, and the contents of the work vary greatly depending on the situation. Therefore, it is necessary to use razors with different applications on the way, and the practitioner needs to prepare a plurality of razors with different guards and cutting tools in advance and replace them with the most suitable one according to the degree of hair conditioning. Therefore, in addition to the work of changing the razor, there is a problem in that it is necessary to secure a place for placing them and the work efficiency is lowered.

  The present invention has been developed on the basis of such a situation, and an object thereof is to provide a hair-shaving razor that has little damage to the hair, can cut the hair in a natural state, and is excellent in workability.

  The invention according to claim 1, which solves the above problem, includes a main body having a holder for inserting a guard, a guard for holding the cutting tool, and a cutting tool, and the main body generates heat capable of heating the holder. A hair-shaving razor characterized in that the body is incorporated.

  The present invention is characterized by improving a conventional hair-shaving razor and incorporating a heating element for heating the blade. The heat generated from the heating element is transmitted through a material having excellent thermal conductivity such as metal to heat the holder. The holder is in contact with the blade through the guard, and when the holder is heated, heat is quickly conducted to the blade. The heating element may take any form, but one that uses electricity is simple and highly safe, and specific examples include a ceramic heater.

  The power supplied to the heating element can be easily supplied by connecting an electric cord to the main unit, but it can be cumbersome to handle the electric cord when styling, and it is possible to incorporate a power source such as a battery into the main unit. It is. In addition, in order to prevent accidents such as fires and burns, the heating element needs to be protected by using a fuse or thermostat to prevent overheating, as well as safety measures such as stopping energization after a certain period of time. In addition to using heat-resistant materials around the heating element, it is necessary to take measures to prevent heat from being transferred to the handle.

  By overheating the cutting tool, the hair was conventionally cut only by force, but in the present invention, since the action of heating the hair is added, the hair is locally softened by heat, and the load required for cutting is increased. It can be reduced and damage can be suppressed. Moreover, since the cut surface hardens after being softened, the occurrence of split ends can also be prevented. However, if the temperature of the blade is too high, the hair may be damaged by heat, and there is a problem such as the generation of a specific odor. If the temperature is low, the effect is not exhibited, so sufficient temperature control is necessary. In the present invention, it is not intended to burn off the hair with heat, and a heating element is used to support haircutting with a razor.

  The invention described in claim 2 is a hair razor characterized in that the main body is provided with a plurality of holders for mounting a plurality of guards, and at least one holder can be heated by the heating element.

  Conventional hair-shaving razors have been provided with one cutting tool attached to one main body, but the present invention is characterized in that a plurality of holders are provided in one main body, and a plurality of cutting tools can be attached simultaneously. The number and position of the holders are not limited, but the individual cutting tools are often used for different applications and should be arranged so as not to affect each other as much as possible. For example, when there are two holders, It arranges symmetrically with respect to. With this arrangement, when cutting the hair, if the hand holding the main body is moved toward the body, it can be cut with one blade, and conversely, if the hand is moved away from the body, the other blade can be cut. . At this time, use holders with different groove sizes and intervals for each cutting tool, and increase the cutting amount with one cutting tool at the initial stage, and reduce the cutting amount with the other for finishing. It can be easily used according to the usage.

  In addition, when multiple holders are provided in one body, various forms are possible, such as heating one holder intensively with one heating element, or having individual heating elements for each holder, but restrictions on size etc. Therefore, a structure in which heat is conducted from one heating element to all holders is generally used.

  According to a third aspect of the present invention, the main body is composed of a grip portion and a tip portion having a plurality of holders, and the tip portion has a structure that can turn around an axis extending in the longitudinal direction of the main body. It is characterized by that. When cutting hair, the most natural action is to move the hand holding the body closer to the body. On the other hand, the invention described in claim 2 is provided with a plurality of holders in one main body, and it is desirable that the cutting tool sandwiched between any holders can be used in this natural operation. Therefore, when the main body is divided into a tip portion provided with a holder and a grip portion gripped by a hand during use, and the tip portion can be turned around an axis extending in the longitudinal direction of the main body, the grip portion is It is possible to change the arrangement of the cutting tools by turning only the tip while gripping.

  Simply making the tip of the main body turnable is extremely dangerous and inconvenient because the cutting tool is not fixed. Therefore, the joint portion between the tip portion and the grip portion is provided with some kind of locking means so that it cannot normally rotate, and it is necessary to take measures such as releasing the locking means by performing an operation such as pressing a button. In addition, when the heating element is incorporated inside the tip of the main body, the structure should be able to cope with the twisting of the wire.

  Moreover, when performing an ideal cut, like the invention of Claim 4, it is desirable to set the temperature at which a cutter is heated by a heat generating body to the range of 130 to 180 degreeC. By limiting the heating temperature in this way, heat is transferred instantly when the hair touches the blade, the hair becomes soft quickly, the blade becomes more smooth, and the tip of the hair also changes to a spherical shape. In addition to preventing such troubles, it is not hot enough for the hair to burn, so there is no specific odor. Therefore, workability is improved, the life of the cutting tool is extended, and it is possible to provide the customer with a fancy hairstyle. The hair-shaving razor according to the present invention is heated to such an extent that it will cause burns if it is accidentally contacted with the skin, but it is assumed that it is used by a limited technician having expertise such as a beautician. There is no problem at all, and the blade is heated to a temperature that is impossible to achieve with a general-purpose razor that directly touches the skin, such as shaving, in order to achieve ideal hair conditioning.

  As in the first aspect of the invention, by providing the function of heating the cutting tool with a heating element, the force acting when cutting the hair can be reduced to prevent the occurrence of damage, and the cutting surface can be heated by heat. Since it becomes hemispherical, the occurrence of split ends is also prevented. Also, by reducing the load at the time of cutting, conventionally it was necessary to give moisture to the hair prior to hair conditioning, but in the present invention it can be used in a dry state and the hairstyle can also be confirmed sequentially, so as desired. It can be finished in style.

  A plurality of guards having different purposes such as a guard capable of cutting a large amount of hair and a guard capable of cutting a small amount of hair for finishing by providing a plurality of holders in one main body as in the invention of claim 2 Cutting tools can be attached to the main body in advance, and different cutting tools can be selected immediately when necessary, so various haircuts can be performed continuously without interrupting operation, reducing time and labor. Can be reduced.

  Since the tip portion provided with the holder can be turned as in the invention described in claim 3, the arrangement of the cutting tool can be changed while the grip portion is gripped by hand, so that a plurality of holders are placed in an unreasonable posture. It can be used easily and can be further reduced in time and labor.

  By limiting the heating temperature of the cutting tool as in the invention described in claim 4, it is possible to adjust the hair while suppressing damage to the hair as much as possible, and the cutting edge of the cutting tool becomes in an optimum state, and the working time is shortened. In addition, there is an advantage of extending the life of the blade and the blade, and in addition, there is no unique odor when the hair burns, and the most ideal leather cut can be provided.

  FIG. 1 is a perspective view showing a structural example of a hair razor 1 according to the present invention. The main body 2 for attaching the cutting tool 7 is composed of a tip part 3 provided with holders 5a and 5b and a grip part 4 provided with irregularities on the outer surface so as to fit the hand when used, and the two holders 5a and 5b are provided at the tips. Centering on the part 3, it is installed so that it may oppose. Each holder 5 can be fitted with a standard cutting tool 7 via guards 6a and 6b, and each holder 5 has the same shape as the cutting tool 7, but the guards 6a and 6b The form is different. Since the guard 6a attached to the holder 5a has a narrow gap between adjacent grooves 8, a large amount of hair can touch the cutting edge 9 at a time and cut, but the guard 6b attached to the holder 5b at the opposite position is Since the distance between adjacent grooves 8 is wide and the amount of hair touching the blade edge 9 is limited, it is mainly used during finishing. Since the end of the guard 6 is located outside the cutting edge 9, even if a finger or the like approaches the cutting tool 7, there is no danger of injury due to contact with the guard 6 alone.

  A heating element 11 using ceramics is incorporated in the distal end portion 3 of the main body 2 as shown by a broken line, and the heat generated therefrom is first transmitted to the holder 5, and the cutting tool 7 is passed through the guard 6. Overheated. Electric power supplied to the heating element 11 is supplied from an electric cord 12 extending from the end of the grip part 4, and a switch 13 for energizing the heating element 11 and a lamp 14 indicating an operating state are provided on the upper surface of the grip part 4. Equipped. In addition, the tip 3 has a structure that can turn around an axis 10 that penetrates the main body 2 in the longitudinal direction. However, the tip 3 does not always turn freely, and usually a gripping portion is provided by a locking mechanism 17 incorporated therein. 4 and one. However, when the button 18a installed on the upper end side of the distal end portion 3 is pressed, the locking mechanism 17 is released, and the device can turn freely. In the process of cutting the hair, if it is desired to replace the blade 7 to be used for the final finishing, the user presses the button 18a with the finger while grasping the grip 4, and then turns the tip 3 in the middle of FIG. ) And then the state shown in FIG. The state shown in FIG. 1C is a state after the tip 3 is turned 180 degrees, the guard 6b having a wide interval between the adjacent grooves 8 is on the upper side, and the tip 3 is fixed by the locking mechanism 17 again.

  2 is a cross-sectional view showing the structure of the distal end portion 3 of the main body 2 and its surroundings. FIG. 2 (a) is a cross-sectional view taken along the line AA in FIG. 1, and FIGS. A cross section is shown. However, illustration of the guard 6 and the cutting tool 7 is omitted in FIG. The distal end portion 3 and the grip portion 4 are connected to each other via a joint 19 so that the distal end portion 3 and the grip portion 4 can be freely rotated about the axis 10. The joint 19 has a sliding surface with a circular cross section and can be freely swung in the circumferential direction, but movement in the direction of the axis 10 is restricted. Further, the heating element 11 is incorporated in the distal end portion 3, but the heating element 11 is fixed to the arm 20 extending from the grip portion 4, and the heating element 11 does not move even when the distal end portion 3 rotates. In addition, in order to monitor the temperature of the heating element 11, a temperature sensor 15 is also incorporated in the distal end portion 3, and it is possible to detect a case where the temperature becomes abnormally high or a prescribed temperature is not reached. In addition to the heating element 11 and the temperature sensor 15, the switch 13 and the lamp 14 are connected to a control device 16 incorporated in the grip portion 4.

  The locking mechanism 17 for restricting the turning of the distal end portion 3 has a structure in which a notch is formed at a location where the outer edge of the joint 19 is extended, and the bottom of the button 18 is engaged with the notch. When the button 18a is not pressed as shown in FIG. 2 (a), the bottom of the button 18a is engaged with the notch, and the distal end portion 3 does not pivot freely. At this time, the locking mechanism 17 does not exist on the lower button 18b. And when a practitioner turns the front-end | tip part 3 in order to change the cutting tool 7, the button 18a is pushed first and the latching mechanism 17 is cancelled | released. When the tip 3 is turned 180 degrees, the bottom of the button 18b engages with the notch and is fixed again.

  2 (b) and 2 (c) show the cross-sectional shape of the tip 3, and (b) shows a state in which the tip 3 is fixed so that it cannot turn, and (c) shows a state in which the tip 3 is turning. Is shown. The holder 5 for attaching the blade 7 penetrates the inside and outside of the outer skin of the tip 3 and is in contact with the heating element 11 inside. When the tip portion 3 is turned, the holder 5 may slide on the outer peripheral surface of the heating element 11, so that the outer periphery of the heating element 11 is formed in a curved surface and covered with a film with little wear. Since the heating element 11 is fixed in a floating state in the distal end portion 3, most of the generated heat is transmitted to the holder 5.

  FIG. 3 is a diagram showing a configuration example of an electric device incorporated in the razor 1 of the present invention. In order to quickly soften the hair with heat and perform the work without generating odor, it is desirable to adjust the temperature of the blade edge 9 to around 150 ° C. Therefore, a control device 16 is incorporated in the grip portion 4 so that the blade edge 9 can maintain this temperature and can prevent abnormal heat generation. The lamp 14 indicating the operating state uses a light emitting diode, and can be lit in three colors of green, red and orange. When the electric cord 12 is plugged into the outlet and the switch 13 is turned on during use, the energization of the heating element 11 is started, and the temperature sensor 15 starts measuring the temperature of the heating element 11. When the specified temperature is not reached from the information from the temperature sensor 15, the lamp 14 is lit in orange to indicate this to the user. When the specified temperature is reached, the lamp 14 is lit in green to notify that the temperature has reached an appropriate temperature. Further, when the temperature rise greatly exceeds the regulation, the power supply to the heating element 11 is stopped and the lamp 14 is lit red at the same time. In addition, the control device 16 has a timer function. When a certain time such as 15 minutes elapses after the switch 13 is turned on, the power supply to the heating element 11 is stopped and the lamp 14 is lit in red and turned off. Prevent accidents caused by forgetting.
