Problems solved by technology

At the same time, because the hair dryer is directly facing the head of the human body, the electromagnetic waves of the formed electric field and magnetic field directly act on the head of the human body, which is very easy to interfere with the nervous system and cause problems such as hair loss; moreover, among the users who use the hair dryer, women account for more Most, pregnant women's use safety is not guaranteed

specific Embodiment I

[0057] like Figure 1-9 , in order to realize the above method, a hair dryer electromagnetic shielding assembly applying the above electromagnetic shielding method includes: a casing 1, a gear mechanism 2 and an electromagnetic shielding mechanism 3; wherein, the gear mechanism 2 is arranged on the casing 1 above, used to adjust the wind speed of the hair dryer; the electromagnetic shielding mechanism 3 is arranged in the housing 1, linked with the gear mechanism 2, and used to adjust the wind speed of the electromagnetic shielding mechanism 3 according to the gear position of the hair dryer Filtration performance: the purpose of adjusting the electromagnetic shielding mechanism 3 according to the gear position is achieved through the linkage between the gear mechanism and the electromagnetic shielding mechanism 3 .

[0058]Specifically, the electromagnetic shielding mechanism 3 includes: an air outlet component combination 301, an air inlet component combination 302, and a li...

specific Embodiment II

[0067] Specific embodiment II: In specific embodiment I, the connecting piece 3033 is connected with the air outlet component assembly 301 and the air intake component assembly 302, such as Figure 4 In daily work, the fourth connection part 3023 or the second connection part 3013 may be suspended in the air by the rigidity of the connection part 3033, which affects product reliability.

[0068] like Figure 9 , in order to solve the above problems, an axial projection is provided in the housing 1, such as a reinforcing rib 1A, which is in contact with the outer side walls of the fourth connecting part 3023 and the second connecting part 3013, and the movement of the connecting part 3033 No interference occurs, so as to ensure that the fourth connecting part 3023 and the second connecting part 3013 are held up, and the rigidity of the connecting part 3033 is no longer used to ensure the reliability of the product; at the same time, the fourth connecting part 3023 and the The ...

specific Embodiment III

[0070] An electromagnetic shielding hair dryer includes: the hair dryer electromagnetic shielding assembly as described above; of course, it also includes: a fan, a heating unit, and a control panel. Since they are all existing technologies, they will not be described in detail herein.

[0071] It needs to be clarified that: in order to facilitate the matching between the cardan shaft 3031 and the housing 1 , bearings or other mechanisms that facilitate the rotation of the cardan shaft 3031 relative to the housing 1 can be provided at the positions where the cardan shaft 3031 is connected to the housing 1 .

[0072] It needs to be clarified that electromagnetic shielding paint coatings are provided on the outside and / or inside of the housing 1 and the rotating grip body 201 described herein, such as the multifunctional magnetic-conductive synthetic mica pearlescent pigment disclosed in Chinese patent CN103694746; or, the housing Body 1 and rotating holding body 201 are all made...

Abstract

The invention aims at providing a blower electromagnetic shielding method and assembly and a blower. The blower electromagnetic shielding assembly comprises a shell, a gear mechanism and an electromagnetic shielding mechanism. The gear mechanism is arranged on the shell and used for adjusting the air speed of the blower; the electromagnetic shielding mechanism is arranged in the shell, linked with the gear mechanism and used for adjusting the filtering performance of the electromagnetic shielding mechanism according to the gears of the blower; through linkage of the gear mechanism and the electromagnetic shielding mechanism, the purpose of adjusting the electromagnetic shielding mechanism according to gears is achieved. The telescopic electromagnetic shielding mechanisms are arranged at the air outlet and the air inlet of the blower respectively; the length of the electromagnetic shielding mechanism is controlled according to the gear of the blower, the air outlet and the air inlet are subjected to electromagnetic shielding, the electromagnetic shielding mechanism is controlled to change according to the gear change, and therefore the electromagnetic filtering performance of the electromagnetic shielding mechanism is adjusted.

Description

technical field [0001] The invention relates to the field of hair dryers, in particular to an electromagnetic shielding method, an assembly and a hair dryer for solving the electromagnetic radiation problem of the hair dryer. Background technique [0002] The hair dryers we use every day for drying hair dry wet hair or style it by blowing warm or cold air. The cold air flow or the warm air flow is exhausted and blown by the fan driven by the motor to form an electric hair dryer. [0003] The above-mentioned hair dryer generally includes a casing, a fan, a heating unit and a control panel; the above-mentioned casing generally includes a hand-held part, one end of the casing is used as an air inlet, and the other end is used as an output end for discharging the hot air heated by the heating unit. [0004] Because the existing heating units on the market generally use heating coils, such as nickel-chromium wire or nickel-iron wire. When the heating unit is energized and heate...
