Description
Technical field
The utility model relates to a kind of hair dryer equipment, is specially the quiet hair dryer of a kind of impedance type, belongs to technical field of living goods.
Background technology
At present, hair dryer has very large deleterious noise in use, the sound source composition of sound is complicated: produced primarily of motor blade when air inlet and air intake and airflow strikes, here noise is maximum, general is to arrive 105-115db at top grade, in addition, clash into air outlet air-flow and outer casing inner wall in motor air-out, the noise sent with heating wire and other structural impact inner and the airflow noise of air outlet, form the sound source of noise pollution, and hair dryer air duct is little, air-flow and collision in air duct and the complex structure sent, noise is that many places send, return resonance mutually, the simple noise problem suppressing hair dryer from aerodynamic principle, different model need be related to and have different internal structures, it is large that technology contains face, and air quantity and the wind speed facing upward only noise and also need to ensure air outlet should be taken into account, hair dryer noise problem has become a long-standing problem like this, so the noise pollution at one's side that hair dryer produces never well solves.
For solving each above technical problem, the utility model provides the quiet hair dryer of a kind of impedance type, its structure is simple, easy to use, reliable, by studying for a long period of time and feasibility preliminary experiment, utilize advanced noise elimination, the technology such as acoustic insulation shock-proof, targeted subsection harnessing, the noise after noise abatement reaches country's the 4th class Standard of Environmental Noise.
Summary of the invention
For above-mentioned situation, for solving the defect of prior art, the object of the utility model just there is provided the quiet hair dryer of a kind of impedance type, it comprises shell, motor, PTC fever tablet, adjustable noise blast pipe back pressure core, sound-absorbing antidetonation film and copper silencer, it is characterized in that, shell is provided with air inlet and air outlet, motor is arranged on inside air inlet end, PTC fever tablet is arranged on inside air opening end, the air outlet slitless connection of adjustable noise blast pipe back pressure core and motor, the outer casing inner wall of the surrounding of the fan blade of motor sticks fire-retardant sound-absorbing antidetonation film, air inlet is provided with copper silencer.
Further, as preferably, copper silencer is the copper silencer of grains of sand type.
Further, as preferably, the air inlet diameter of quiet hair dryer is greater than the diameter of the air outlet of quiet hair dryer.
Further, as preferably, the inwall at 4 millimeters, the air outlet place apart from quiet hair dryer is provided with counterclockwise internal thread.
The beneficial effects of the utility model: the utility model provides the quiet hair dryer of a kind of impedance type, its structure is simple, easy to use, reliable, by studying for a long period of time and feasibility preliminary experiment, utilize advanced noise elimination, the technology such as acoustic insulation shock-proof, targeted subsection harnessing, the noise after noise abatement reaches country's the 4th class Standard of Environmental Noise.
Accompanying drawing explanation
The structural representation of the quiet hair dryer of a kind of impedance type that Fig. 1 provides for the utility model.
Wherein, 1, PTC fever tablet, 2, counterclockwise internal thread, 3, adjustable noise blast pipe back pressure core, 4, sound-absorbing antidetonation film, 5, copper silencer.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, the utility model provides the quiet hair dryer of a kind of impedance type, it comprises shell, motor, PTC fever tablet 1, adjustable noise blast pipe back pressure core 3, sound-absorbing antidetonation film 4 and copper silencer 5, shell is provided with air inlet and air outlet, motor is arranged on air inlet end, PTC fever tablet 1 is arranged on air opening end, the air outlet slitless connection of adjustable noise blast pipe back pressure core 3 and motor, the outer casing inner wall of the surrounding of the fan blade of motor sticks fire-retardant sound-absorbing antidetonation film 4, air inlet is provided with copper silencer 5.
In the present embodiment, copper silencer 5 is the copper silencer of grains of sand type.The air inlet diameter of quiet hair dryer is greater than the diameter of the air outlet of quiet hair dryer.The inwall at 4 millimeters, the air outlet place apart from quiet hair dryer is provided with counterclockwise internal thread 2.
The utility model installs the copper silencer 5 of grains of sand type by the air inlet at quiet hair dryer, it is the air outlet diameter being greater than quiet hair dryer by the air inlet diameter design of quiet hair dryer, such when can resist wind speed in noise elimination impedance, air quantity and the wind speed of air outlet can be ensured, should be noted that, want the rotating speed of expanded motor, keep the wind speed of normal electrical blowing, the noisiness of air inlet can be suppressed simultaneously.By around motor blower fan contact position, namely at the inwall place of position hair dryer, the acoustic insulation shock-proof film 4 of the flame-proof environmental protection of exchange premium mouth, effectively can lower noise sound source herein.At the air outlet of motor, adopt the back pressure core 3 of adjustable noise blast pipe, directly and its slitless connection, air-flow sound is out by after a series of impedances such as the backflow of this device turns to, noise can deduct original about 20 decibels, make counterclockwise internal thread 2 at the inwall in distance 4 millimeters, hair dryer exit, effectively can increase wind speed.Meanwhile, electro-heat equipment of the present utility model does not adopt heating wire, and the PTC fever tablet 1 adopting thickness thicker, eliminate original noise sent because of heating wire and airflow strikes.Because noise can produce resonance, like this when the noise at the above-mentioned each position of subsection harnessing hair dryer, the noise that quiet hair dryer of the present utility model produces, the noise after noise abatement reaches country's the 4th class Standard of Environmental Noise.
