Description

The invention relates to the field of satisfying human needs, in particular, to the design of a hair care device for drying and / or styling hair.

Currently, hand-held hair dryers are used for hair care, in particular for drying hair, which are convenient due to the possibility of the targeted supply of strong air pressure (cold or hot), the expense of short drying time and due to the fact that these devices are suitable for home use. If there is a need to curl hair, then the user uses a separate device or device that allows one or another known method to curl hair. With all the positive qualities that reduce time and ease of use, there are drawbacks to using it as a hairdryer. and curling devices, consisting in the need to control the air temperature and drying time to avoid drying out and burning the hair. In general, exposure to hot air when drying or heating curls during curling is undesirable for hair, as it changes its structure and violates the protective scaly layer. The use of hair dryers for drying requires strict compliance with the requirements of the instructions for this device in terms of choosing the air temperature, the distance from the hair dryer nozzle to the hair, drying time, etc. These requirements are generally not met. Similar requirements must be strictly followed when curling to avoid brittle hair and damage.

In addition, when using a hand-held hairdryer, you need to use a comb, as a result, both hands of the user are occupied. A similar situation occurs with the use of special curling devices such as plates or tongs. All this creates inconvenience and carries the risk of damage to the hair.

The practice of drying hair while maintaining its structure intact shows that the best drying technology is natural drying, that is, drying of raw (not wet) hair with air without using heat is more than the temperature in a living room (natural home environment), with periodic shaking of hair or separation them on new locks for ensuring uniform air exchange. This is a rather long procedure, but it allows you to keep the hair intact, especially their scaly protective cover. Drying time is almost the only drawback, but it was he who did not give the possibility of widespread use of this healthy technology.

Attempts have been made to create devices that would accelerate this process of natural drying by increasing the speed of movement of air around raw hair. Historically, it has been observed that moisture without air circulation will remain hanging around the laundry with a steam cloud, preventing further evaporation, which means drying of the laundry. That is why on the street, with a light breeze, things dry faster than in the sun, but with complete calm. The transported air stream naturally captures droplets of moisture from the surface of the crude object and is carried away by the air stream, thereby drying it. This principle was the basis of the created devices for drying hair without the use of heating elements.

So. A device for drying and curling hair is known, comprising a nozzle in communication with an air injection source (blower), the other end of which is connected to rubber tubes located around the head, in the walls of which there are through holes communicating with this nozzle and directed away from the hair (US 4692594, A45D 20/12, A45D 20/46, A45D 20/52, publ. 08.09.1987).

The tubes are made of rather large lengths, fan out from the nozzle and are interconnected by transverse leather straps, due to which the tubes are not adjacent to each other, but spaced at certain distances relative to each other. In this case, the tubes are made with hollow protrusions having through holes. To dry the hair, the pipe is laid along the back with its end with the tube attachment unit in the lower occipital zone of the head, then the tubes are laid on top of raw hair from above, spreading the tubes to the length of the leather jumpers. And the protrusions are deepened into the hair before contact with the scalp. After that, the blower pumps air into the tubes.

The disadvantage of this device is the inconvenience of its use, due to the fact that it is difficult for the user to correctly place everything on his head and turn on the blower. The tubes are not attached to the head in any way, they simply lie on the hair and any tilting of the head can lead to displacement of the tubes. Therefore, the placement of the device on raw hair should be done by an assistant. The main disadvantage of this device is that during drying, the technology of natural drying is violated. Tubes are laid on raw hair and when air is applied, drying occurs only along the outer layer of hair. The holes in the rubber tubes are located outside, and the tubes themselves lie on raw hair. The supplied air leaves the tubes in the direction away from the head, creating the effect of turbulence in the area around the head (simulating a light breeze).

Internally located hair remains almost raw. Entering through the protrusions recessed in the hair, the air passes through the hair close to the protrusion, but does not fall on the hair located between the protrusions. In this case, after laying the tubes, all hair becomes pinned.

The uniformity of drying of all hair is disturbed. With such drying, an unremovable vapor-air mixture is formed in the internally located hair. Therefore, there is a greenhouse effect, leading to stretching and rupture of hair.

The technology of natural drying is based on the fact that air should blow all the hair or strands made up of them simultaneously and from all sides. In this case, all hair will dry at the same time.

The present invention is aimed at achieving a technical result, which consists in improving performance due to uniform blowing of the separated hair strands simultaneously from all sides.

The specified technical result is achieved in that the device for drying and curling hair, containing a pipe for supplying air, to which are connected located around the head of the tube, in the walls of which there are through holes communicated with this pipe, is provided with a support element in the form of a hollow located on the user's head the housing associated with the specified pipe for communication with a source of air injection and which is made with elements of support on the forehead and the back of the head or lower neck area, and the tubes are made then walled of polymer material with holes in the walls along the entire wall surface of each tube, located around the head in the direction from the body down to the shoulders of the user and curved convex in the direction from the user's head, the transverse dimension of at least part of these holes is greater than the thickness of the tube wall and more than the transverse the size of the bridge between adjacent openings, each tube being made with radially extending radially protruding from the wall, located on the outer side not with respect to the tube side of the tube facing towards the user.

In addition, seats can be made in the housing for installing at least one fan and an autonomous power source supplying it to supply air from the environment through the pipe. A heating element can also be placed in the housing for heating the flow of air entering the tubes.

These features are significant and interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

The present invention is illustrated by a specific example of execution, which, however, is not the only possible, but clearly demonstrates the possibility of achieving the desired technical result.

FIG. 2 is a front view in a 3/4 view of the device of FIG. 1

According to the present invention, there is considered a design of a device for drying and curling long and medium length hair, which does not require the use of the user's hands during use. At the same time, this device allows air to dry all hair in a short period of time due to the natural blowing of each strand. This device also allows you to curl hair during a drying session.

The device for drying and curling hair (Figs. 1 and 2) contains a support element located on the user's head in the form of a hollow body 1 made or connected with a nozzle 2. This nozzle can be used to communicate with an air injection source (hair dryer, vacuum cleaner, blower and any device that generates air flow at the outlet). In this case, the air flow is forced into the cavity of the housing. A design variant is possible when a fan with power from a battery (battery) is placed in the housing. In this case, when the fan is turned on, air is sucked into the cavity of the housing.

The body is made with an element 3 supporting on the forehead and an element 4 supporting on the back of the head or lower neck area of the head. The supporting elements 3 and 4 are made in the form of arched plates (in the form of concavity, in fact, repeating the shape of the surface of the forehead or neck). These elements are connected to the housing by jumpers or rod elements or plates in the form of ribbons. Jumpers or rod elements, bearing elements, as well as the body, are made of polymer material. For supporting elements and for jumpers or stubble plates or tapes, an elastically deformable polymer can be used, which, after putting the case on the head, press the supporting elements against the user's head. Rigid polymeric material can also be used for jumpers: since jumpers or rod elements are made of small thickness with a sufficient length, these jumpers will work as an elastic element. The supporting elements 3 and 4 can be rigidly connected to the jumpers, but can be connected to them through an adjustable swivel joint, by means of which it is possible to adjust the fit of the supporting element to the corresponding part of the head.

The housing with supporting elements and elements of their connection to the housing can be made in the form of a single non-separable part or collapsible.

Tubes 5 made of a polymeric material are rigidly connected to the housing or, for example, are inserted into the housing (connected with it). The tubes are made thin-walled with through holes 6 in the walls along the entire wall surface of each tube and communicated with the body cavity. The tubes are located around the user's head in the direction from the body down to the shoulders of the user and are arched convex in the direction from the user's head. The transverse dimension of at least a portion of these holes is greater than the wall thickness of the tube and larger than the transverse dimension of the bridge between adjacent openings. Each tube is made with radially extending from the wall beam-shaped protrusions 7 located on the outside of the tube with respect to the side of the tube facing the user. The ends of the tubes are muffled. When injection air is fed into the cavity of the housing, this air is distributed over the volume of the cavity and enters the tubes, air leaves the tubes through openings in the walls of the tube.

From the casing the tubes go down distantly with respect to each other: they can have a parallel arrangement or diverge to the sides. In any case, the tubes are located around the head and at some distance from it. This creates ease of use, as there is no contact with the head. This is also necessary so that there is free space around the tubes for air to escape from the tubes.

A design feature of the claimed device is that the tubes, in fact, are support rods for twisting strands of hair on them. The user, having put the case with tubes on his head, spins strands on the tubes. The hair is divided into strands and each strand is laid on the corresponding tubular support. Hold the strands on the tubes radially directed beam-like protrusions 7. They provide fixation of the strands on the tube. The through holes in the tube are made over the entire area of the tube wall and have dimensions at which these holes are not a resistance (choke) for air to flow. Air without resistance penetrates out of the tube, blowing hair. The strand is dried simultaneously along its entire length and from all sides. After going outside, the air rises up, carrying out external blowing with an upward flow.

When reducing the size of the through holes, braking of the injected air occurs, since part of the holes is blocked by a strand. In this case, a whistle or hiss appears, indicating an increase in the rate of air exit from the tube. But an increase in speed is a negative result, since the air outlet velocity is high, and this exit stream captures only part of the surface of the strand. The natural airflow mode stops. Local drying occurs, in which part of the strand dries faster than the rest of the hair in this strand. A strand of hair twisted on the tube forms a hair column. To dry it, it is necessary that, with such a column, holes remain in the tube in a sufficient volume of air permeability to ensure that the entire strand is blown. This is subject to the condition that any transverse dimension of at least a portion of the holes in the tube must be greater than the thickness of the tube wall and larger than the transverse dimension of the bridge between adjacent openings.

Since, during the drying process, the hair strands on the tubes are in a spiral state, after drying, the freed strand has a wavy appearance, which indicates a curl.

A possible embodiment of the device (Fig. 4 and 5), in the housing 1 of which there are seats for installing the fans 8 and the batteries 9 or batteries supplying them. The current supply wires are connected to the electrical part with a power switch 10 and a button for switching the operation modes of the fans. Such a device is fully autonomous. An example of execution is also possible, when only fans 8 are placed in the housing 1, connected through conductive wires and a power switch 10 with a plug, which allows connecting the fans to the centralized power supply system of the room.

An embodiment of the device is possible in which a heating unit or a heating element with a spiral is additionally built into the housing. The unit operates in two modes: in the first, the temperature corresponds to the first minimum heating position of ordinary hair dryers. In the second mode, significantly warm air is blown out. There is also a position in which the heating is turned off, putting the device into ECO mode.

The process of natural hair drying requires periodic shaking of the hair to remove vapor-air clusters between the strands. In the inventive device, due to the separation of hair into strands, there is no need for shaking and combing, since there are no areas of accumulation of raw hair with stale unbroken air in them.

The use of warm or hot air, by analogy with the work of ordinary hair dryers, the curling and drying process is accelerated with all the negative consequences inherent in the use of ordinary hair dryers. But for gentle drying of hair there is no need to use hot air. It is enough to use room temperature air. It is also essential that there is no need to create a high pressure of the air supplied to the tubes. Drying takes place due to blowing off raw hair with a stream of air at which this moisture is captured from the hair. That is, the drying process is determined only by the presence of air movement relative to the hair. And for this, even a slight pressure of air is enough. In this regard, the device provides gentle drying. Naturally, increasing ambient temperature speeds up the drying process. And an increase in the pressure or the rate of exit of air from the tubes can create discomfort during drying due to the difference in the temperature of raw hair and the incoming cool air (an increase in the speed of air movement lowers its temperature).

The present invention can significantly reduce the time for drying hair, allows you to simultaneously do a curl. This eliminates the likelihood of damage to the hair by temperature drying.
