Description
Far infrared hair dryer

The invention relates to a far infrared hair dryer in which an air-conducting, conical sleeve is provided in a main body so that the shape of the main body can be designed in a streamlined manner, wherein two opposite cross-shaped positioning frames are accommodated in the conical sleeve, which are also conical in shape corresponding to the conical sleeve, between which a ceramic heating element is clamped, which can emit high-temperature far infrared radiation, so that no dry feeling occurs during use.

A conventional hair dryer is mainly a hot air hair dryer, which, as shown in Figure 4, consists of a tubular main body (30) whose end sections form an air outlet opening (31) and an air inlet opening (33), the air inlet opening (31) being provided with a filter net (32). A fan motor (34) is provided on the air inlet side in the main body (30), whereby the air is sucked in and discharged by rotating a fan (35) so that the air is circulated along the tubular main body

(30) flows out of the air outlet opening (31). On the air outlet side in the main body (30) there is a heating element (36) which is designed as a resistance coil and is connected via a power line to a switch (38) by means of which the hot or cold air and the air speed can be selected.

The above-mentioned conventional hair dryer belongs to the group of products with high heat energy consumption and is widely used. However, there is no temperature control for cost and stability reasons, so that the temperature of the hot air fluctuates with the selected air speed and the duration of use. In particular, when used at a low air speed and for a long time, overheating is often caused, which either leads to the resistance coil burning or the air outlet opening deformation.

(31) of the main body (30), so that the safety requirement is not met. In addition, the hair is damaged by the air that is too hot.

For this reason, the inventor, considering the disadvantages of conventional solutions, has developed the far infrared hair dryer according to the invention, which provides a honeycomb-shaped ceramic heating element which, when heated, emits far infrared

·

can emit radiation, thereby achieving temperature control and ensuring operational safety.

The invention is based on the object of creating a far infrared hair dryer, the heating element of which has a high degree of efficiency and enables easy assembly, through which the high temperature can be maintained, so that the manufacturing costs are reduced and the safety of use is ensured.

The invention is based on a further object of creating a far infrared hair dryer which is easy to install due to the simple heating element and has a health-care effect due to the far infrared radiation.

The structure, features and functioning of the invention are explained in more detail below using the attached drawings. They show:

As shown in Figures 1-3, the far infrared hair dryer according to the invention has a shape similar to that of a conventional hair dryer and consists essentially of a hollow main body (10), which can also be streamlined and thus has an L-like shape, and a rear cover (11) which covers the rear of the main body (10). The main body (10) is designed as a conical tube, the end with a smaller diameter forming the air outlet opening (12) into which a flat air guide tube (13) can be inserted in order to concentrate the air. In the main body (10) there is provided a conical sleeve (25) for guiding the air, which has a smooth inner surface and in which a cross-shaped positioning frame (20) is received, which consists of two plates which have the same conicity as that of the sleeve (25), so that the positioning frame (20) rests tightly against the inner surface of the sleeve (25). The end with a larger diameter has a recess (201) in which a metal ring (202) is housed, which is connected to a power line and on the outside of which a heating element (22) made of ceramic and is a product of patent 69696 is glued. The two sides of the heating element (22) are coated with conductive silicon in order to be heated by current from the metal ring (202). When the ceramic heating element reaches a predetermined temperature, a large amount of far infrared radiation is emitted. Due to the diffusion of the far infrared radiation and the constant property of its high temperature, dry and hot air is not produced. On the outside of the heating element (22) there is also provided a conical positioning frame (21) which has a shape similar to the positioning frame (20). On the side of the positioning frame (21) facing the heating element (22), a recess (211) is also provided, in which a metal ring (212) is also accommodated. Therefore, the heating element (22) can conduct current by contact with the front and rear metal rings (202, 212), so that an electric circuit is closed. On the outside of the positioning frame (21), an axle seat (23) is provided, which is provided with a recess and serves for mounting the fan motor (24), wherein a projection (241) is provided on the frame of the fan motor (24), which can be brought into engagement with the recess of the axle seat (23), so that the fan motor (24) can be easily positioned on the axle of the main body (10). The fan motor (24)

is then attached to the main body (10) using two screws (16) and covered by the air inlet net (14) of the rear cover (11), whereby the main body (10) and the rear cover (11) can be connected to one another by the projections and recesses on the connecting surfaces and the screws (16) that are screwed into the main body through the screw hole (15) on the periphery of the cover. The slide switches (18) on the handle (17) can be used to select hot or cold air and adjust the air speed.

The hair dryer according to the invention is mainly a ceramic or glass heating body (22) coated with a heating layer and formed in a honeycomb shape. This heating body is clamped between two conical cross-shaped positioning frames (20), (21) each provided with a recess (201), (202) and accommodated in a conical air-conducting sleeve (25) which can adapt to various shapes of the main body (1) and protect the main body from heat. In addition, the heating body (22) has a high temperature constant property, thereby ensuring safety in using the hot air and minimizing the noise of the fan motor at a speed of over 10,000 due to the pressure reducing effect of the heating body (22). Since the heating body (22) is formed in a honeycomb shape, its volume can be reduced so that the hair dryer can have a compact shape. The circuit is provided with slide switches (18) which are arranged outside the main body (10) on the handle (17) and enable multi-stage adjustment. Furthermore, the constant high temperature property can protect the hair dryer from overheating, so that safe use is guaranteed. The far infrared radiation of the hair dryer according to the invention also has a health-promoting effect.

In summary, it can be said that the far infrared hair dryer according to the invention allows easy installation, ensures safe use and has a health-promoting effect.
