Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

The embodiment provides a hair drier, which can be used for quickly drying hair for a user and providing convenience for the user to maintain the hair.

The blower includes a housing 400 of hollow construction, the housing 400 being generally tubular in shape. The diameter of the housing 400 may be the same along the axis of the housing 400, or may be larger at the center and smaller at the ends, or the diameter of the housing 400 may gradually decrease along the direction of the airflow. The specific structural design of the housing 400 is determined according to the requirements of different internal structures of the hair dryer, and the embodiment is not limited thereto.

It will be appreciated that the hair dryer further comprises a heating assembly 700 disposed within the housing 400, the heating assembly 700 being utilized to heat air to dry hair. Illustratively, the heating assembly 700 is a heating wire.

Further, the hair dryer further comprises a support frame 100, a driving assembly 200 and a circuit assembly 300. The supporting frame 100 is provided with an accommodating cavity 110, the driving assembly 200 is disposed in the accommodating cavity 110, the circuit assembly 300 is electrically connected to the driving assembly 200, and the circuit assembly 300 is disposed in the accommodating cavity 110. When the circuit assembly 300 is powered on, the driving assembly 200 can be controlled to rotate at a high speed to generate an air flow in the blower, the air flow flows in from the air inlet, is heated by the heating assembly 700, and then flows out from the outlet direction of the housing 400, so that an air flow circulating from the driving assembly 200 to the heating assembly 700 is formed in the housing 400. One side of the driving assembly 200 departing from the heating assembly 700 is an air inlet, and one side of the heating assembly 700 departing from the driving assembly 200 is an air outlet. Optionally, along the airflow direction generated by the driving assembly 200, the circuit assembly 300 is located at the downstream of the driving assembly 200, and by adopting the structural design, the airflow entering from the air inlet firstly passes through the circuit assembly 300 to take away the heat generated on the circuit assembly 300, and then flows through the heating assembly 700 to be heated, so that the effect of utilizing the initial airflow entering the hair dryer to dissipate the heat of the circuit assembly 300 is achieved, thereby being beneficial to avoiding the short circuit or the open circuit of the circuit assembly 300 due to high temperature, and prolonging the service life of the hair dryer.

The drive assembly 200 includes a flapper 210 and a driver 220. The baffle 210 is disposed on the inner wall of the accommodating cavity 110, and the driving member 220 is disposed on the baffle 210, so as to fix the driving member 220, and improve the safety and stability of the driving member 220 during the operation. Illustratively, the drive 220 is a fan comprising a mounting shaft and a plurality of blades. The mounting shaft is fixed to the baffle 210, and the plurality of blades are arranged in an inclined manner at intervals in the circumferential direction of the mounting shaft, and are rotated by the inclined blades to form an air flow. It can be understood that the baffles 210 may be two sets, and the two sets of baffles 210 are respectively disposed at the front and rear ends of the blower, where the baffles 210 may be fixed on the inner wall of the accommodating cavity 110 or may be non-fixed.

As an alternative, the accommodating chamber 110 sequentially includes a first accommodating chamber 111 and a second accommodating chamber 112 from upstream to downstream, the first accommodating chamber 111 is used for arranging the driving assembly 200, the second accommodating chamber 112 is used for arranging the circuit assembly 300, and the diameter of the first accommodating chamber 111 is smaller than that of the second accommodating chamber 112, so that the cross section of the fluid entering the heating assembly 700 can be increased while the heat dissipation area is further increased, and thus the air flow entering the heating assembly 700 in unit time is increased under the condition of the same air speed, and the hair drying efficiency is further improved.

Since the fan will generate a certain vibration during operation, the friction between the supporting frame 100 and the casing 400 is increased, and even noise is generated. In order to avoid this problem, the hair dryer further comprises a buffer member 500, wherein the buffer member 500 is disposed between the casing 400 and the support frame 100, and the buffer member 500 is used for absorbing and reducing noise. Illustratively, the buffer 500 may be made of sound-absorbing cotton or an elastic material, which has a good damping and noise-reducing effect, and is convenient to purchase and low in cost. Preferably, the shock absorbing member is in interference contact with the housing 400, so as to increase the shock absorbing effect and reduce the vibration space of the supporting frame 100.

As an alternative, the hair dryer further includes a filter assembly 600 detachably disposed on the support frame 100, and the filter assembly 600 is located on a side of the driving assembly 200 away from the circuit assembly 300, so that the air sucked into the inner wall of the support frame 100 by the rotation of the blades of the driving assembly 200 is filtered by the filter assembly 600, thereby preventing dust or hair in the air from being sucked into the casing 400, which is beneficial to improving the service life of the hair dryer. And the filter assembly 600 is detachably provided to facilitate cleaning of incoming dust or hair.

Further, the filter assembly 600 includes a first filter sock 610 and a second filter sock 620. Be equipped with a plurality of first filtration holes on the first filter mantle 610, the second filter mantle 620 covers and establishes on first filter mantle 610, and is equipped with a plurality of second filtration holes on the second filter mantle 620, and the diameter in first filtration hole is less than the diameter in second filtration hole to reach the fluid that gets into the hair-dryer and carry out double filtration's mesh, improve the filter effect.

After long-term use, a large amount of dust and the like are easily attached to the interior of the hair drier, so that a user is difficult to clean the hair drier. In order to facilitate the use of users, in the embodiment, the blades can rotate in the forward direction to realize the blowing effect, and can also rotate in the reverse direction to enable airflow to flow in the reverse direction, so that the airflow enters from the air outlet of the hair drier and flows out from the air inlet to realize the purpose of self-cleaning the inside of the hair drier.

When the airflow reversely flows, in order to avoid the accumulation of dust at the step position generated by the diameter difference between the first accommodating cavity 111 and the second accommodating cavity 112, the first accommodating cavity 111 and the second accommodating cavity 112 are in arc transition, so that the airflow resistance is reduced, and the dust accumulation at the transition position of the first accommodating cavity 111 and the second accommodating cavity 112 is avoided as much as possible.

Optionally, an electric wire outlet may be further disposed at the joint position of the first receiving cavity 111 and the second receiving cavity 112, the hair dryer further includes a handheld portion 800, the handheld portion 800 is connected to the housing 400 at the electric wire outlet, and the electric wire of the circuit assembly 300 may be connected to the handheld portion 800 at the electric wire outlet, connected to an external power source, or connected to circuit elements (such as a button and a light display) distributed in the handheld portion 800. Through the mode, the circuit arrangement in the hair drier can be simpler. Of course, the wire outlet may also be disposed at the position of the first receiving cavity 111 or the position of the second receiving cavity 112, which is not limited in this embodiment.

It is noted that the basic principles and main features of the present invention and the advantages of the present invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration only, and that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
