[0001] The utility model relates to the field of household appliances, in particular to an air inlet shell and an electric hair dryer. BACKGROUND

[0002] With the development of economy and the improvement of people's living standards, people's requirements for the quality of life are also higher and higher, so that the electric hair dryer gradually becomes an essential product for most families. In the prior art, the air inlet channel of the electric hair dryer is unique, which leads to insufficient air inlet of the electric hair dryer, so that the air outlet is affected, the user's experience is reduced, and the insufficient air inlet may cause the internal electronic components of the electric hair dryer to be difficult to dissipate heat, shortening the service life of the electric hair dryer. SUMMARY

[0003] Therefore, it is necessary to provide an air inlet shell and an electric hair dryer for the problem of insufficient air inlet of the electric hair dryer.

[0004] An air inlet shell for an electric hair dryer, comprising: a rear cover assembly provided with a first air inlet hole; a mounting shell, the rear cover assembly being arranged on the mounting shell; a front shell assembly provided with a receiving cavity, the mounting shell being arranged on the front shell assembly, the front shell assembly being provided with a third air inlet hole; a fan assembly built in the receiving cavity; a filter cover arranged on the mounting shell and / or the fan assembly, the filter cover being provided with a second air inlet hole, the second air inlet hole being in communication with the third air inlet hole, a negative pressure port of the fan assembly being in communication with the filter cover, the first air inlet hole, the second air inlet hole and the negative pressure port of the fan assembly sequentially communicating to form a first fluid channel; and a handle assembly arranged on the front shell assembly, the handle assembly being provided with a air supply cavity, the air supply cavity, the third air inlet hole, the second air inlet hole and the negative pressure port of the fan assembly sequentially communicating to form a second fluid channel.

[0005] The above discloses an air inlet shell for a hair dryer, which provides the first step support for the hair dryer to realize the blowing function by providing the first air inlet hole in the rear cover assembly, that is, providing sufficient air for the fan assembly and heating element inside the hair dryer to generate continuous and stable airflow output, while keeping the air pressure inside and outside the hair dryer balanced to ensure that the airflow can smoothly pass through and blow out. The rear cover assembly is arranged on the mounting shell to provide stable support for the rear cover assembly, avoiding falling off due to vibration generated when the hair dryer is working, and increasing the overall structural strength and stability of the rear cover assembly. The fan assembly is arranged in the accommodating cavity provided in the front shell assembly, and the negative pressure port of the fan assembly is in communication with the filter cover, and the second air inlet hole provided in the filter cover is in communication with the first air inlet hole and the negative pressure port to form a first fluid channel, which provides the first air inlet channel for the hair dryer to realize the basic function of the hair dryer, and this structure enables the air entering the hair dryer to be concentrated in one position for effective filtration, improving the filtration effect and reducing the entry of dust and impurities into the interior to cause harm to the user by blowing out foreign matter inside the hair dryer, while also protecting the components inside the hair dryer and prolonging the service life of the hair dryer. In addition to the air inlet channel provided in the above structure, a second air inlet channel is also provided in the handle assembly of the hair dryer. Since the handle assembly is arranged on the front shell assembly, and the air supply cavity provided in the handle assembly is in communication with the third air inlet hole provided in the front shell assembly, the airflow entering from the handle assembly passes through the air supply cavity to the fourth air inlet hole, then from the fourth air inlet hole to the third air inlet hole, and finally through the filter cover into the interior of the hair dryer. The air supply cavity, the third air inlet hole, the second air inlet hole and the negative pressure port of the fan assembly are in communication in sequence to form a second fluid channel, and in combination with the first fluid channel, the design of this double air inlet structure can increase the air inlet amount of the hair dryer, thereby improving the air speed and air volume of the hair dryer, while the motor and circuit board assembly of the hair dryer generate a large amount of heat when working, and the double air inlet structure can more effectively suck in external cold air to help the motor and circuit board assembly dissipate heat and reduce temperature, ensuring normal use. In addition, the double air inlet structure avoids the singleness of the air inlet channel, which can reduce the noise of the hair dryer to a certain extent, meet the actual use requirements of users, and improve the market competitiveness of the hair dryer.

[0006] In one embodiment, the first air inlet hole is provided in a plurality of numbers, and the plurality of first air inlet holes are arranged along the circumference of the rear cover assembly. By providing a plurality of first air inlet holes in the rear cover assembly, the amount of air entering the interior of the hair dryer can be greatly increased, thereby improving the strength and speed of the air outlet and accelerating the efficiency of drying the hair of the user, while the plurality of air inlet holes in the groove help to more evenly distribute the entering air in the interior of the hair dryer, ensuring that the blown air is more stable and uniform. Compared with a single air inlet hole, the plurality of air inlet holes can more effectively suck in air to improve the air speed and air volume of the hair dryer. The structure of the groove can reduce the resistance of the airflow when entering the hair dryer, thereby reducing the noise generated by the airflow.

[0007] In one of the embodiments, the mounting shell is provided with a through hole, the filter cover is inserted into the through hole, and part of the filter cover is located between the mounting shell and the rear cover assembly. By setting a through hole at the bottom of the mounting shell and inserting the filter cover into the through hole, the air flow can be made more fine and soft, avoiding the overloading of the fan assembly due to the too large air flow intensity, prolonging the service life of the fan assembly, and at the same time, the part of the filter cover located between the mounting shell and the rear cover assembly plays a filtering role, avoiding some large objects from entering the inside of the hair dryer to interfere with the normal work of the internal components.

[0008] In one of the embodiments, the second air inlet hole is provided in multiple numbers, and the multiple second air inlet holes are arranged at the bottom of the filter cover and the sidewall of the filter cover. By arranging multiple second air inlet holes at the bottom and sidewall of the filter cover, since the second air inlet hole is smaller than the first air inlet hole, it plays a further filtering role to filter some hair, paper scraps and other sundries in life, and the arrangement of multiple second air inlet holes can make the air pass through the filter cover from different directions, increasing the filtering opportunity and improving the filtering effect, better protecting the elements inside the hair dryer, and also reducing the influence of impurities on hair, and at the same time, the smaller air inlet hole is more helpful to make the entering air more evenly distributed in the inside of the hair dryer, and the uniform air inlet can make the wind generated by the hair dryer more stable and continuous, avoiding the situation of too large or too small local air volume, and improving the use experience.

[0009] In one of the embodiments, part of the filter cover is clamped between the mounting shell and the fan assembly. By clamping part of the filter cover between the mounting shell and the fan assembly, the filter cover can be stably installed in the inside of the hair dryer, avoiding the filter cover from falling off due to the vibration generated during the work of the hair dryer, affecting the normal use of the hair dryer, and ensuring the user experience.

In addition, the arrangement of the plurality of first buckles can effectively prevent the rear cover assembly from loosening due to vibration or other external forces during use, further improving the fastening of the rear cover assembly.

[0011] In one of the embodiments, the first buckle hole is provided with a mounting slot and a buckle hole, the mounting slot and the buckle hole are communicated, and the plurality of first buckles can enter the mounting slot and be arranged in the buckle hole one by one. By arranging the first buckles in the buckle hole of the first buckle hole, the stable connection between the rear cover assembly and the mounting shell is realized. Only the rear cover assembly needs to be rotated to match the first buckle with the first buckle hole of the mounting shell, which greatly saves the installation and disassembly time, improves the production efficiency, and is also convenient for users to maintain the hair dryer daily, prolonging the service life of the hair dryer.

[0012] In one of the embodiments, the mounting shell is further provided with a plurality of second buckle holes, and the plurality of second buckle holes are arranged along the circumference of the outer side wall of the mounting shell. By arranging a plurality of second buckle holes on the mounting shell and arranging the plurality of second buckle holes around the outer side wall of the mounting shell, the uniform distribution of the plurality of buckle holes can make the connection between the mounting shell and other parts more stable.
