Description

Hair dryer structure

The utility model provides a hair dryer, in particular to a structure of a hair dryer which breaks through the traditional wind blade and has the advantages of excellent balance when the blade is running at a high speed and which does not vibrate when the sound is small.

According to the hair dryer, the air is sucked into the casing through a fan inlet through a fan, and the air is heated by a heating device in the casing, and then blown outward through the air outlet of the casing for the hair. Provide functions such as drying or shaping.

At present, the hair dryers on the market focus on the size of the wind, heating effect or appearance to enhance the value of the product. However, the value of the product is limited to this, and there is still a gap in the actual function, such as safety. The hair dryer easily sucks the user's hair into the fan from the rear during the operation of the fan, causing the hair to accumulate in the fan and the motor for a long time, causing the motor to burn out, and the balance is poor when the fan rotates at a high speed, and the noise is low. The vibration is also large, and the heating temperature of the heating coil is very high, and the user often gets burnt when holding the air duct casing.

Therefore, how to solve the above problems and problems in the past, that is, the creators of the new type and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Therefore, in view of the above-mentioned shortcomings, the applicants of this new type have collected relevant information, and through multi-party evaluation and consideration, and through years of experience in the industry, through continuous trial and modification, they have designed such breakthrough traditional blades. A new patented person who makes the wind blade operate at high speed and has a good balance, and the sound is small and does not vibrate.

The main purpose of the present invention is to effectively increase the balance of the rotation of the fan element and prevent the hair from being sucked by the power unit through the ring portion and the stop portion of the fan member, thereby effectively maintaining the smooth operation of the shaft of the power unit and protecting the shaft. User's hair.

A further main object of the present invention is to further enhance the air guiding property through the deflector of the outer side wall of the motor seat.

Another main object of the present invention is to achieve a shorter time in the assembly through the modular heating coil set, and the heat generation effect is better.

Another main object of the present invention is to allow the heat generated by the heat generating device to be insulated from the ribs of the outer side wall of the guiding member, so that the user does not have a hot accident when the user holds the outer casing.

The main structure of the present invention capable of achieving the above object includes an outer casing in which a power device, a fan element, a heat generating device, and a guiding member are housed, and in a structural connection relationship, the power device connects the fan member, and the heat generating device It is disposed on one side of the power device, and is provided with a guiding element between the heat generating device and the inner wall of the outer casing; and further described by a more detailed component, the outer side wall of the motor seat has a plurality of baffles, and the heat generating device comprises a base And a modular heating coil set fixed on the base, and the outer side wall of the guiding element has a plurality of ribs to form at least one passage between the guiding element and the inner wall of the outer casing; The power unit drives the fan element to rotate at a high speed. In the operation, the ring portion can be used to increase the rotation balance of the fan element, and at the same time, the stop portion can prevent the hair from being entangled and accumulated on the power unit shaft through the use time in a more effective manner. The heart affects the operation of the power unit and causes damage; in addition, the heat generated by the heat device is carried out by the wind energy generated by the fan element to the outer casing. In addition, the wind can be guided by the baffle to make the overall wind conductivity better. In addition, the heat generated by the heat generating device is very high in temperature, so the cold passage is formed through the isolation of the ribs. With the hot aisle, the temperature of the outer casing is not too hot and very safe. In addition, since the heating coil set is modularized during production, it can be assembled without any manual winding when combined with the base, which is very time-saving. Labor saving.

With the above technology, it is easy to suck the user's hair into the fan from the rear for the conventional hair dryer, causing the hair to accumulate in the fan and the motor for a long time, causing the motor to burn out, and the heating temperature of the heating coil Very high, the user often breaks through the problem of being burnt when holding the air duct casing, and achieves the practical progress of the present invention as the above advantages.

In order to achieve the above objects and effects, the technical means and structure adopted by the present invention are described in detail in the preferred embodiment of the present invention, and the features and functions thereof are as follows.

Please refer to the first to fourth figures, which are cross-sectional views of the preferred embodiment of the present invention to the first line AA of the first drawing. It can be clearly seen from the figure that the present invention comprises: an outer casing 1; In the power unit 2 in the outer casing 1, the power unit 2 includes a motor base 21, a motor 22 coupled to the motor base 21, and a rotating shaft 23 coupled to the motor 22. The end of the rotating shaft 23 is as follows The fan element 3 is fixed, and the outer side wall of the motor base 21 has a plurality of baffles 212, and the baffle 212 is a curved surface; a fan element 3 coupled to the power unit 2 has a side edge The ring portion 31 has a rotation balance for increasing the rotational balance of the fan element, and the other side has a stop portion 32 for preventing the hair from being caught in the axial center of the power unit 2; and is housed in the outer casing 1 and located at the power a heat generating device 4 on the side of the device 2, the heat generating device 4 includes a base 41, and a modular heating coil set 42 fixed on the base 41; and a heat generating device 4 and the outer casing a guiding element 5 between the inner walls of the body 1, the outer side wall of the guiding element 5 has a plurality of ribs 51, The at least one guide element 5 and passage 6 between the inner wall of the housing body 1 is formed.
