Description

The technical field to which the invention relates.

The invention relates to human hygiene, namely to shaving, and can be used in the manufacture of razors and razor cartridges.

The level of technology.

An analogue may be a razor (RF patent 2352453, published September 20, 2008), containing blades, an injection system for supplying fluid from the reservoir to the dosing hole for applying to the skin during shaving, an electric drive, an electric current source.

The disadvantages of the analogue:

- Does not produce electrical myostimulation (stimulation of facial muscle tissue).

- Does not strengthen the walls of blood vessels.

- activity of fatty glands is not suppressed.

The prototype can be a razor described in RF patent 2404044, published on 11/20/2010. The razor contains a handle, at least two blades, and an electric current source is located in the handle. These features of the prototype coincide with the features of the invention.

The razor is configured to function from a chemical power source. In the handle is a motor that provides vibration to the razor. The razor contains a button and the button is configured to transmit the force applied to the button to an elastic membrane located below the button.

The disadvantages of the prototype:

- Does not produce electrical myostimulation (stimulation of facial muscle tissue);

- does not strengthen the walls of blood vessels;

- activity of fatty glands is not suppressed.

SUMMARY OF THE INVENTION

The objective of the invention is the implementation of electrotherapy when shaving.

The problem is solved due to the fact that the razor containing the handle, at least two blades, and an electric current source is located in the handle, differs from the prototype in that the electric current source located in the handle is connected to a DC to AC device ( inverter), the terminals of the inverter are connected to the blades, the razor is configured to supply alternating electric current to the blades.

The technical results of the invention are as follows.

- the razor during shaving produces electrical myostimulation (stimulation of the facial muscle tissue). At the same time, a massage effect is achieved. The muscles during shaving are in good shape;

- a razor during shaving produces a therapeutic effect - strengthening the walls of blood vessels. The opening of reserve capillaries occurs, as a result of which the supply of blood to the facial skin area improves. The skin is saturated with oxygen;

- a razor during shaving inhibits the activity of the fatty glands - while the skin color becomes more natural and the oily sheen disappears;

- a razor during shaving improves metabolic processes in the area of the skin where shaving is carried out;

- a razor during shaving improves the functional state of skin cells.

An electric current flowing over the surface of the skin during shaving with a declared razor has a pronounced effect and causes a pleasant sensation. Stimulates the absorption and synthesis of nutrients. Rapid excretion of metabolic products occurs. Accelerates tissue repair.

Information confirming the possibility of carrying out the invention.

The razor (see FIG. 1) contains a handle 1, two blades 2 and 3. An electric current source 4 is located in the handle 1. An electric current source 4 located in the handle is connected to the blades 2 and 3, in particular, the positive terminal of the current source 4 is connected to the blade 2, and the negative is connected to the blade 3. The razor is configured to supply electric current to the blades after pressing button 6 and turning on the toggle switch 7.

Figure 2 shows a diagram of a razor powered blades 2 and 3 by alternating electric current. The current from the source 4 is fed into the device for converting direct current to alternating current (inverter) 8. The terminals of the inverter 8 are connected to the blades 2 and 3. The blade 5 is not connected to the current source.

Figure 3 shows a diagram of a razor with a vibrator 9, which is connected through a toggle switch 7 to a current source 4. In addition, in the razor, the blades 2 and 3 are supplied with alternating current from the inverter 8.

In general, the razor can be configured to feed DC blades to the vibrator.

The device operates as follows.

The shaving person presses the button 6, the contact of the toggle switch 7 is closed. Electric current from the source 4 is supplied to the blades 2 and 3 (see figure 1). In another case (see figure 2), the electric current from the source 4 through the inverter 8 is supplied to the blades 2 and 3.

During shaving, a vibrator 9 can be used.

Blades 2 and 3 are in contact with the wet surface of the skin. The liquid that contacts the blades closes an electric circuit between blades 2 and 3. Electric current flows from a current source 4 through blades 2 and 3 along the skin surface.

A constant voltage is applied to the blades, the value of which is from 0.01 V to 12 V.

An alternating or pulsating voltage is applied to the blades, the value of which is from 0.01 V to 12 V.

An alternating or pulsating voltage of more than 12 V can be applied to the blades, but the current frequency is from 25,000 Hz to 1 MHz.

The authors conducted experiments in which a voltage of 0.01 V, 0.1 V, 1 V, 3 V, 4.5 V, 12 V was applied to the blades. The current in the experiments was constant.

The authors also conducted experiments in which a voltage of 0.01 V, 0.1 V, 1 V, 3 V, 4.5 V, 12 V, 24 V, 60 V was applied to the blades. The current in the experiments was variable with a frequency of 25,000 Hz, 50,000 Hz, 150,000 Hz .

The razor during shaving produces electrical myostimulation (stimulation of the facial muscle tissue) - while achieving a massage effect. Impulses penetrate deep into the muscle tissue, thereby causing the muscles to contract more often, due to this - the facial muscles during shaving are in a tone that continues after shaving.

A razor during shaving produces a therapeutic effect - strengthening the walls of blood vessels, this is achieved by improving trophism (nutrition) of tissues and metabolism in them. During the influx of fresh blood, reserve capillaries open, resulting in improved blood supply to the facial skin. The skin is saturated with oxygen, which makes the skin more elastic.

The razor during shaving suppresses the activity of the fatty glands - while the skin color becomes more natural and the oily sheen disappears;

A razor during shaving improves metabolic processes in the area of the skin where shaving is performed.

A razor during shaving improves the functional state of skin cells, as currents increase blood flow and improve metabolic processes.

The electric current flowing over the surface of the skin during shaving with a declared razor has a pronounced effect and causes a pleasant sensation. Stimulates the absorption and synthesis of nutrients. Rapid excretion of metabolic products occurs. Accelerates tissue repair, especially in people with sensitive skin.

The experiments with the claimed experimental razor, the authors conduct for six months. The above effects during the experiments are confirmed.

Claims (1)

A razor containing a handle, at least two blades and an electric current source located in the handle, characterized in that the electric current source is connected to a device for converting direct electric current to alternating electric current in the form of an inverter, the terminals of which are connected to the blades, with the possibility of applying alternating electric current to the blades during shaving.
