Description

Photo-thermal type air comb

Technical Field

The application relates to the technical field of hairdressing tools, in particular to a photo-thermal type air comb.

Background

The hair drying principle of the traditional hair dryer is that cold air sucked by a fan is blown out from an outlet of the fan, the cold air is heated by a high-power heating element and then is quickly blown to hair through an air outlet, and moisture of the hair is heated and evaporated or is taken away by the quickly flowing hot air, so that the purpose of drying the hair is achieved. However, the traditional blower has high power, large electric power waste and high temperature of heating wires/sheets, and increases the risk of scalding skin and damaging hair when in use; the higher the blower power, the higher the temperature, the more likely the hair and scalp will be damaged; when the hair is wet, the hair scales with the outer layer structure are in an open state (the effect of the hair scales is to protect nutrients in the hair), and when the hair scales are opened, high temperature is directly applied to hair fibers and hair cores, so that moisture in the hair marrow is quickly evaporated (the effect of the hair marrow is to influence the luster and the shade of the hair, and the high temperature changes the coloring agent of the hair), so that the hair is tarnished and yellow and is bifurcated; the higher the power and the higher the temperature of the blower, the higher the rotating speed requirement of the blower is under the condition of rapidly applying hot air to hair, the larger the noise generated therewith is, and the cost is correspondingly increased; in order to meet the power requirement of the high-power heating and high-speed fan, the instrument cannot adopt wireless power supply, so that the trouble of storage is increased, and the convenience of use is greatly reduced.

The hot air comb is a modified product of the electric hair drier, and the hair nursing tool can comb hair and massage scalp when drying hair, so the hot air comb becomes a necessary hair dressing article gradually. However, in the prior art, the comb heads of the hot air comb are connected with the machine body in an interference fit and hot stamping mode, but the interference fit has high requirements on machining tolerance precision of the comb heads and the machine body, the relative rotation difficulty of the comb heads and the machine body is high, the control is inconvenient, the hot stamping operation efficiency is low, and the operation is troublesome. The existing hot air comb also has the effect of sterilizing by the infrared lamp tube arranged on the machine body, but the light rays irradiated on the comb head are too divergent to achieve the effect of sterilizing. And the existing hot air comb has a complex structure and is inconvenient to carry.

Referring to fig. 10-11 in combination, dry hair gas flow path 200 is shown with arrowed lines: under the action of the fan 40, external cold air is sucked from the intervals of the comb teeth and the hair areas on the comb teeth, enters the fan 40 through the ventilation channel 11, flows to the two lamp tubes 30 through the fan ventilation opening 42, heats cold air flowing through the surfaces of the lamp tubes 30 (namely, the inside of the lamp tube grooves 150) into hot air by the heat energy effect of the luminous fields of the lamp tubes 30 (tungsten wires or carbon wire light sources such as halogen lamp light sources), and then flows through the hair areas after the cold air is heated into hot air by the heat energy effect of the luminous fields of the lamp tubes 30, so that the air flow completes the first circulation and enters the next circulation; the hot air flows through the hair area and then flows out through the ventilation channel 11 and is sucked into the fan 40 again, flows to the two lamp tubes 30 through the fan ventilation opening 42 to be heated for the second time to form hot air, and flows out through the ventilation channel 11 and enters the next internal circulation after flowing through the hair area again, so that the circulating air is repeatedly circulated, the flowing air is short in heating time, high in heat stability and more in moisture carried away.

Specifically, under the fan 40, external cold air is sucked from the gaps inside the hair area on the comb teeth and the intervals inside the comb teeth, the cold air is sucked into the fan 40 through the ventilation channel 11 and the fan ventilation opening 43, is guided into the lamp tube groove 15 through the fan ventilation opening 42 from the inside of the guide cover 103, and after the cold air flowing through the surface of the lamp tube 30 is heated into hot air by the heat energy effect of the luminous field of the (tungsten wire or carbon wire light source such as halogen lamp light source) lamp tube 30, the hot air flows to the hair area from the side opening 150 of the lamp tube groove 15, and the hair is divided into a plurality of small parts by the comb teeth 13, so that the contact area between the hot air and the hair and the flow speed of the hot air are increased conveniently; after flowing through the hair area, the hot air flows out through the ventilation channel 11 and is sucked into the fan 40 again through the fan ventilation opening 43 (at the moment, the temperature of the air flow of the first circulation is slightly higher than that of the initial ambient air flow), flows to the tungsten filament or carbon filament light source lamp tube 30 through the fan ventilation opening 42 to heat for the second time to form hot air, and after flowing through the hair area again (at the moment, the moisture of the hair is reduced compared with that of the first circulation due to the action of near red light, the external heat energy required by the hair is correspondingly reduced), the hot air flows out through the ventilation channel 11 to enter the next internal circulation (repeated circulation is performed in such a way, the flowing air is heated for a short time, the heat stability is high, and more moisture is taken away).

The photo-thermal type air comb 100 of the present embodiment is provided with an auxiliary dry-hair airflow path, referring to fig. 10: under the action of the fan 40, external cold air is sucked from the auxiliary ventilation opening 18 of the comb shell and is sucked into the fan 40 through the ventilation channel 11 to participate in the circulation of the air flow for drying hair.

The photo-thermal air comb 100 of this embodiment dries the hair principle:

1) Near infrared light action: the near infrared light with the wavelength of 900-2500nm can be absorbed by water molecules and generate high-frequency vibration to generate internal heat so as to evaporate the water; the lamp tube 30 of tungsten filament or carbon filament light source is adopted, and the near infrared light wave is utilized to irradiate the wet hair, so that the light wave and water molecules on the surface layer of the hair generate internal heat to promote the evaporation of water on the surface of the hair, and the light generated by the light source irradiates the hair hung on the comb teeth through the side opening 15 of the lamp tube groove 15, thereby achieving the effect of assisting in drying the hair;

2) The action of heat energy: cold air is sucked by the fan 40 and flows to the lamp tube (tungsten filament or carbon filament light source) 30 through the fan ventilation opening 4, the flowing cold air is heated into hot air by utilizing the heat energy effect of the luminous field of the lamp tube 30 and then flows to the hair area, and meanwhile, the hair is divided into a plurality of small parts by utilizing the comb teeth, so that the contact area between the hot air and the hair and the flow speed of the hot air are increased conveniently; the hot air flows through the hair area and then flows out through the ventilation channel 11 (serving as a circulating air outlet), then is sucked into the fan again through the ventilation opening of the fan, flows to the tungsten filament or the carbon filament light source through the ventilation opening of the fan for secondary heating to form hot air, and flows through the hair area again, and the hot air is repeatedly circulated in such a way, so that the flowing air is short in heating time, high in heat stability and more in moisture carried away;

3) Cyclic induced draft action: because the traditional hair dryer needs to suspend a certain distance from the head, part of hot air is lost in the environment space due to heat dissipation of wind during hair drying and does not effectively act on the hair, and cold air which is required to be sucked into the environment from beginning to end in the hair drying process is heated into hot air through the heating wire and then acts on the hair through space radiation, so that the power consumption of the product is greatly increased due to heat loss and continuous input of the cold air, and the hair drying efficiency is reduced;

the embodiment adopts the circulating heating air, so that the timeliness of hair drying is improved, and the beneficial effects of the circulating heating are that the later section of the hair drying process is less and less in moisture content of hair, the hair is drier, and the heat consumed by the hot air when acting on the hair is less and less; therefore, the power consumption required by the later stage in the hair drying process is smaller and smaller, the heat maintenance degree is high, the heating time is short, the utilization rate of heat energy is effectively improved, and the waste of heat energy is reduced.

In the above embodiments, the comb 1 is not limited to the rectangular parallelepiped shape, and may be, for example, a cylinder perpendicular to the axis of the handle, and accordingly, the lamp tube 30 may be mounted on the comb 1 in a diametrical direction or in a direction parallel to the diametrical direction.

It will be appreciated that the tubes 30 may be mounted on either side of the comb housing, in a diametric, axial direction, or in other suitable locations.

The photo-thermal air comb 100 of the present application has the following advantages:

1) Low power consumption, high efficiency: due to the action of the tungsten filament or carbon filament light source double energy sources (light energy and heat energy), the heat source (the tungsten filament or carbon filament light source lamp tube 30 is adopted) can be infinitely close to the hair, the temperature is lower than that of a traditional blower, the heat energy loss and the power loss generated between the traditional blower and the hair due to the distance are eliminated, and the double beneficial effects of low power consumption and high-efficiency hair drying are realized;

2) Portability: under the dual beneficial effects of reducing power consumption and improving efficiency, the product can realize wireless battery design, and the convenience and the storage property of the product in use are greatly improved;

3) Hair care: due to the effect of near infrared light energy generated by a tungsten wire or carbon wire light source, the external heat energy required by the evaporation of the moisture of the hair is greatly reduced; the loss of nutrients caused by high temperature of hair scales and hair medulla is avoided, and the hair structure is effectively protected.

Although embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the present application as defined by the appended claims and their equivalents.
