Description

{Blade Rotary Heat Coil Shaver}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a blade rotation type heat ray shaver, and more particularly, to a blade rotation type heat ray shaver for cutting or removing hair or hair by a heat ray coil inserted into a heat ray axis portion of a blade unit as a rotating cruciform blade.

In general, a razor or epilator is a tool of means for removing or shaving hair, i.e. hair, on the skin of a human body.

Such a razor or epilator may include a razor that cuts or cuts hair using a razor blade, a descender-type forced epilator that removes hair by force, a high-frequency epilator that uses a tweezer to remove hair by using high frequencies, and a laser epilator that uses a laser .

There are aspects of these shavers that I prefer to manually shave, but it is dangerous to give a big and small scar on my face as I have to put the knife right on my face. That is, if the user manually shaves the skin, it scatters the skin of the face finely but not invisibly, causing confusion in the texture of the skin and ultimately making the skin rough.

In addition, the electric shavers change the operation and the operation according to the structure and structure of the electric shaver itself in order to improve the quality and feel of the shaver. In addition to not stabilizing the razor blade, the razor blade is fundamentally stabilized, In many cases.

Therefore, if it is important for the shaver, it is possible to cut the hair more gently, not only to increase the quality and feel of shaving, but also to increase the effect of shaving.

As a conventional technique for solving the aforementioned problems, a heat-transfer type epilator is known in Korean Patent Registration No. 10-0915371.

[0003] However, in the conventional technique, the friction roller is rotated in contact with the skin, and the heat generated from the heat ray is used to remove the hair while the friction roller rotates in contact with the skin. There is the inconvenience that the skin directly contacts with excessive heat generation due to direct skin contact.

Also, users who are familiar with the use of general rotary blade electric shavers have a limitation that provides a sense of shaving different from electric shavers.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art described above, and it is an object of the present invention to provide a device for shaving and removing hair by a heat treatment using a hot wire coil of a platinum alloy inserted in a ceramic- .

It is another object of the present invention to provide a device for safe and hygienic shaving and hair removal through heat sensing by a thermal protection net for protecting skin, a motor with built-in reduction gear capable of speed control finely, and a temperature sensor.

Wherein the pair of unidirectional blades of the blade unit is constituted of a heat ray shaft portion for applying heat to the hair and a brush shaft portion for shaving off the hair which has been squeezed out.

Therefore, the blade rotation type heat ray shaver of the present invention uses a blade unit that is a rotating cross blade instead of a friction roller type, and has a shaving effect similar to that of a general rotary blade type electric shaver, while being shaved by the characteristics of a heat ray shaver .

In addition, the present invention has the effect of removing hairs without pain and skin damage through shaving by heat.

In addition, the present invention has an effect of improving stability through heat sensing by a motor and a temperature sensor with a speed reduction gear built-in type capable of finely controlling the speed and preventing an uncomfortable feeling at the time of shaving.

Further, the present invention provides an effect of ensuring durability, flame retardance and reliability by using a ceramic-based blade unit, a hot-wire coil of a platinum alloy, a brush of a flame-retardant synthetic resin, and a thermal protection network.

FIG. 1 is a schematic view illustrating a configuration of a blade rotary type heat ray shaver according to an embodiment of the present invention. As shown in FIG. 1, a main body housing 100 of the razor includes a thermal protection network 110, a temperature sensor 120, A circuit 130, a motor 140, an embedded battery 150, and a blade unit 160. [

Therefore, the present invention takes the structure of a razor type used to shave or depilate human hair.

In this case, the thermal protection network 110 is a safety net in the form of a metal mesh in the upper part of the main body housing 100. This is a safety net in which the thermal wire coil 172 inserted in the blade unit 160 rotating under the thermal protection network 110 ) Is a protective device designed to protect skin from direct contact with heat due to heat release and to protect skin.

The thermal protection net 110 may be included in a screw-type top cover (not shown) that can be opened and closed to clean and repair the residue of the hair that falls to the inside of the main body housing 100 .

The temperature sensor 120 is connected to one side of the thermal protection network 110 and converts the detected temperature of the thermal protection network 110 into an electric signal in response to heat emission from the hot- And transmits it to the control circuit 130.

The control circuit 130 functions to shut off the power of the hot wire coil 172 when the temperature of the thermal protection network 110 is transmitted by the temperature sensor 120 in excess of 40 degrees.

In addition, the control circuit 130 may include a user input signal such as power on / off inside the main body housing 100, a charging control of the built-in battery 150, a rotation speed of the motor 140, And controls the temperature of the fuel cell 110 automatically.

Fig. 2 is a plan view of a blade unit viewed from above, according to an embodiment of the present invention, Fig. 3a is an axial cross-sectional view of a heat ray shaft portion viewed from A in Fig. 2, Fig. 8 is an axial cross-sectional view of the brush shaft portion as desired;

As shown in the drawing, the blade unit 160 is in the form of a cruciform blade that closely rotates at a lower side of the thermal protection net 110. The pair of unidirectional blades of the cruciform blades are heated by applying heat to the heat ray shaft portion 170, The pair of wings is constituted by a brush shaft portion (180) which shakes off the hair.

Further, the blade unit 160 is made of a ceramic-based synthetic material and has a strong heat and abrasion resistance.

The blade unit 160 of the present invention rotates at a speed of 1 to 5 rps per second by receiving the rotational power of the motor 140 located at the lower part of the blade unit 160 so that the crossing action of the heat ray axis unit 170 and the brush axis unit 180 Can be said to be a wing unit that whips out the hair of the human body while it is slurred. The rotation speed per second can be appropriately adjusted through a control loop.

The rotation speed of the blade unit 160 per second is slower than that of a general rotary blade electric shaver. The rotation speed of the blade unit 160 increases the use time of the motor 140 and reduces power.

At this time, the hot-wire shaft portion 170 generates a hot-wire groove 171 at a predetermined depth, and a hot-wire coil 172 is formed in the hot-wire groove 171 so as to be twisted into a double- As shown in Fig.

In order to drive the hot-wire coil 172 at a low current, it is necessary to sufficiently secure the coil length and increase the resistance. By making the hot-wire coil 172 have a double-spiral structure, the coil length can be sufficiently secured, Can be guaranteed.

For this purpose, the hot wire coil 172 is made of platinum, which is excellent in tensile properties, has high resistance, is very stable in air, moisture, etc., and does not change even when heated to a high temperature and is resistant to acid and alkali and has high corrosion resistance. .

In addition, when a small amount of iridium is added to the platinum, the advantage of pure platinum is maintained and the alloy becomes harder and stronger.

Therefore, the heat coil 172 of the present invention is a heat generating coil having a double spiral structure made of an alloy using platinum (Pt), and receives power from the built-in battery 150 to generate heat of 800 to 1000 degrees Celsius And the hair is heated by applying heat to the human hair to rotate.

The brush shaft part 180 is a wing shaft corresponding to the heat ray shaft part 170 of the uniaxial blade. A brush 181 made of acrylonitrile butadiene styrene copolymer formed at the center of the brush shaft part 180 is formed in such a manner that the brush 181 is formed so as to protrude like the height of the heat ray shaft part 170 and rotate. Therefore, the blade unit of the brush shaft unit 180 is formed to be thinner to some extent by the height of the brush 181 than the heat ray shaft unit 170.

At this time, the brush 181 serves to blow off the hair, which is caught by the hot wire coil in the hot wire shaft portion 170, through the rotation of the brush shaft portion 180.

The motor 140 is a device for transmitting a rotational force to the blade unit 160. The motor 140 may be a DC motor with a reduction gear incorporated therein, which can reduce noise, power consumption and speed control.

The positive and negative contact terminals connected to the hot wire coil 172 are connected to the motor 140 so that power can be supplied without twisting the hot wire coil 172 of the rotating blade unit 160. [ (+) And minus (-) power supply, which are added in the power supply unit (not shown).

Therefore, like the blade unit 160, the hot wire coil 172 can be smoothly supplied with current without being twisted. At this time, a spring is inserted into the contact terminal so as to make contact with the circular electrode more tightly. This is similar to the design of a typical rotatable electrode terminal.

The built-in battery 150 may use a low voltage power source such as a battery or a rechargeable battery that supplies power to the motor 140 and the heat coil 172. At this time, the rechargeable battery may be any one of nickel-cadmium (Ni-Cd), lithium ion, a lithium ion polymer, or a nickel-metal hydride It is possible.

Therefore, the built-in battery 150 not only rotates the motor 140 but also supplies a proper current to the hot-wire coil 172 by the control circuit 130 to heat uniform heat from the hot-wire coil 172 .

In addition, the main body housing 100 of the present invention includes a suction storage module (not shown) for sucking and storing the hairs when the hairs that are caught by the heat ray shafts 170 are shaken by the brush shaft portion 180, ). ≪ / RTI >

Therefore, the present invention relates to a blade-type electric wire coil-type electric razor for cutting or removing hair or hair by a hot-wire coil 172 as described above, It is based on various technical factors that can make texture feel.
