Description

Technical Field

[0001] The utility model relates to the technical field of hair dryers, in particular to a housing component of a hair dryer and the hair dryer. Background Art

[0002] The hair dryer is composed of a set of electric heating wires and a small fan with a high speed. When powered on, the electric heating wires will generate heat, and the wind blown out by the fan will become hot air after passing through the electric heating wires. If only the small fan rotates, but the electric heating wires are not hot, then the wind blown out is just wind without heat.

[0003] Hair dryers are mainly used for hair drying and shaping, but they can also be used for local drying, heating and physical therapy in laboratories, physiotherapy rooms, industrial production, art and other fields. According to the type of motor it uses, it can be divided into AC series-excited type, AC shaded-pole type and DC permanent-magnet type. The advantages of the series-excited hair dryer are large starting torque and high speed, which are suitable for manufacturing high-power hair dryers; the disadvantages are high noise and the commutator has certain interference with telecommunication equipment. The advantages of the shaded-pole hair dryer are low noise, long life and no interference with telecommunication equipment; the disadvantages are low speed, poor starting performance and heavy weight. The advantages of the permanent-magnet hair dryer are light weight, high speed, simple manufacturing process, low cost and good quality at a low price.

[0004] The air outlet of current hair dryers does not blow air evenly, which causes the hair to be rough and tangled easily after being blown, resulting in a poor user experience. Utility Model Content

[0027] See also Figure 1 An embodiment of the utility model provides a housing assembly of a hair dryer, comprising: a housing 10 and an air outlet structure 20.

[0028] An air duct is arranged in the shell 10, and an air outlet structure 20 is arranged at the outlet of the air duct. A plurality of air outlets 21 are arranged on the air outlet structure 20, and the air outlet 21 is connected to the air duct. The plurality of air outlets 21 are arranged on the air outlet structure 20, and the air outlet 21 is in a strip shape, extending in a direction perpendicular to the air outlet direction of the air outlet 21. The extension directions of the plurality of air outlets 21 are parallel to each other. Since the air outlets 21 are arranged side by side and in a strip shape, the airflows blown out by the air outlet structure 20 are all side by side and horizontal, and the airflow is not easy to be chaotic, making the airflow softer, especially.

[0029] In some optional embodiments, multiple air outlets 21 are evenly arranged along the air outlet direction of the surrounding air duct, thereby increasing the blowing range and preventing the air flow from being blown out at a single position, thereby improving the uniformity and stability of the air outlet pressure of each air outlet 21.

[0030] In some optional embodiments, multiple air outlets 21 are symmetrically arranged relative to the center of the air outlet structure 20 to improve the stability of the air outlet structure 20. Since the air outlet structure 20 is arranged at the outlet of the air duct, the center of the air outlet structure 20 is equivalent to being located at the center of the air duct. Therefore, multiple air outlets 21 are symmetrically arranged relative to the center of the air outlet structure 20, which is also conducive to making the wind pressure at the outlet of the air duct from each air outlet 21 similar.

[0031] The size of the air outlet 21 can be designed according to actual needs. For example, in some optional embodiments, the area of ​​the cross section of the air outlet 21 perpendicular to the central axis of the air duct is 200-400 mm2. The wind speed and wind pressure of the air outlet 21 within this area range are relatively gentle, which is beneficial to protecting the hair.

[0032] In some optional embodiments, the width of the air outlet 21 is 1.5-2.5 mm, and the width of the air outlet 21 is controlled to be a suitable width, so that the air outlet 21 is relatively thin, the air outlet is delicate, and the blown air does not excessively heat the hair, thereby avoiding hair damage.

[0033] See also Figure 2In some optional embodiments, a symmetry line 12 is preset on the air outlet structure 20, and the symmetry line 12 is parallel to the extension direction of the air outlet 21 and passes through the center of the air outlet structure 20. The length of the air outlet 21 is longer than the length of the air outlet 21 adjacent to and closer to the symmetry line 12, that is, the length of the air outlet 21 farther from the symmetry line 12 is longer than the length of the air outlet 21 closer to the symmetry line 12. Since an assembly structure 22 is usually required to be provided in the middle of the air outlet structure 20, the assembly structure 22 is used for assembly with the shell 10, and the length of the air outlet 21 close to the symmetry line 12 is relatively short and is distributed on both sides of the assembly structure 22, which is convenient for avoiding the assembly structure 22, and the air outlet 21 far from the symmetry line 12 can be parallel to the side of the assembly structure 22, and its length can be designed to be relatively long, which is beneficial to increase the air output. In this embodiment, the assembly structure 22 protrudes from the side of the air outlet structure 20 away from the air duct, and a recessed structure can be formed on the side of the air outlet structure 20 close to the air duct. The position of the recessed structure corresponds to the position of the assembly structure 22, and the recessed structure and the outer shell 10 are assembled with each other. For example, the recessed structure can be assembled with a bracket set in the air duct.

[0034] It should be noted that the symmetry line 12 is not an actual structure but only a virtual reference line.

[0035] In some optional embodiments, the end faces of both ends of the air outlet 21 are curved surfaces, and the end faces of both ends of the air outlet 21 are arc-shaped in a cross-section perpendicular to the central axis of the air duct, and the end faces smoothly transition to the sides of the air outlet 21, thereby avoiding the formation of corners between the ends and the sides of the air outlet 21, avoiding the corners from easily hiding dirt and being difficult to clean, and also avoiding hair from being easily caught in the corners.

[0036] In some optional embodiments, the air outlet structure 20 is a heat dissipation air outlet structure 20, that is, the air outlet structure 20 is made of a heat dissipation material, and the heat dissipation material can be a plastic with good thermal conductivity, such as polyphenylene ether, polyurethane, polyether amide, etc.

[0037] In some optional embodiments, a handle 11 is provided on the housing 10 to facilitate the user to hold the housing 10 .

[0038] The housing assembly of a hair dryer described above can be applied to a hair dryer, which comprises: a hair dryer assembly and a housing assembly of a hair dryer described above, wherein the hair dryer assembly is connected to the air duct of the housing 10. The hair dryer assembly generally comprises a fan blade and a motor connected to the fan blade, and the fan blade rotates under the drive of the motor and drives the gas to flow.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
