Description

Technical Field

[0001] The present invention relates to the technical field of hair dryers, and in particular to a high-speed hair dryer with low noise and high wind pressure. Background Art

[0002] Hair dryers are common household appliances. When in use, the blower is pointed directly at the head, with the air outlet very close to the user's ears. This produces a lot of noise, which can cause ear discomfort. High-speed hair dryers are particularly prone to this, as their motors continuously run at extremely high speeds. This strong airflow is subjected to significant pressure within the blower's cavity, disrupting the main air duct and generating stray gases. These gases, under high pressure, collide with the cavity's barrier points, producing noise and abnormal sounds, which can have a greater impact on the user.

[0003] In addition to the impact of noise, the stability of the air pressure and air volume is also a factor that affects the user experience. Especially for high-speed hair dryers, a sudden increase or decrease in the air intake will directly affect the air pressure and air volume of the air outlet, making the user noticeably feel that the air volume is sometimes large and sometimes small, which is a bad user experience. Traditional hair dryers generally use a single-duct air intake structure. When the air intake of this single duct is unstable, it will directly affect the air pressure and air volume of the hair dryer. At the same time, the working efficiency of the high-speed motor will also decrease when the air intake volume decreases. Working in an unstable airflow environment for a long time will also reduce the service life of the high-speed fan. The instability of the air intake and outlet volume will change the frequency and amplitude of sound propagation, thereby generating a new source of noise.

[0004] Therefore, how to ensure the stability of the hair dryer's wind pressure and air volume through reasonable air duct design, improve the working efficiency of the high-speed motor, and reduce wind noise have become problems that high-speed hair dryers need to solve. Summary of the Invention

[0026] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1 to 3 As shown, the present invention is a low-noise, high-pressure high-speed hair dryer, comprising a hair dryer 1, a handle 2, and a high-speed motor 3. The hair dryer 1 is provided with an air outlet, a first air inlet 12, a second air inlet 13, and an air duct fusion chamber 14. The first air inlet 12 constitutes a first air duct, the handle 2 is provided with a handle air inlet hole 221, and the handle 2 is connected to the second air inlet 13 of the hair dryer 1 to constitute a second air duct. The first air duct and the second air duct converge into the air duct fusion chamber 14, and the high-speed motor 3 is arranged between the air outlet and the air duct fusion chamber 14.

[0028] The high-speed hair dryer of the present invention is provided with two air inlet structures, namely the air cylinder 1 and the handle 2, which increases the air volume of the air intake, ensures an adequate air supply, and improves the working efficiency of the high-speed motor 3. The hair dryer has the characteristics of high air pressure and high air volume, and reduces the noise generated by the high-speed motor 3 when the air volume is unstable. The air duct fusion chamber 14 is provided to centrally merge the airflows of the two air ducts, and the sound waves generated by the two airflows in different directions are partially offset by each other, thereby reducing the noise of the air intake.

[0029] The air duct 1 includes an air duct air inlet assembly 4 and an air duct air outlet assembly 5. The air duct air outlet assembly 5 is arranged at the air outlet of the air duct 1. The air duct air inlet assembly 4 is connected to the first air inlet 12 of the air duct 1 to form a first air duct. The high-speed motor 3 is arranged between the air duct air outlet assembly 5 and the air duct fusion chamber 14.

[0030] The structure of the air inlet assembly 4 of the duct cooperates with the structure of the handle air inlet hole 221 of the handle 2 to form a dual-duct air inlet structure, which ensures the stability of the air intake volume. The interior of the air outlet assembly 5 of the duct also ensures the stability of the air outlet volume through reasonable air duct design. A silencer structure is also added to the handle 2. Noise reduction designs are made at multiple air flow locations such as the air inlet, the first air inlet 12, the second air inlet 13, and the air duct fusion chamber 14, so that the whole machine has the characteristic of low noise.

[0031] The hair duct 1 also includes a hair duct shell 11, an air outlet, a first air inlet 12, and a second air inlet 13 are arranged on the hair duct shell 11, the hair duct air outlet assembly 5 is connected to the hair duct shell 1 and is located at the air outlet, the hair duct air inlet assembly 4 is connected to the first air inlet 12 of the hair duct shell 11, and the handle 2 is connected to the second air inlet 13 of the hair duct shell 11.

[0032] like Figure 4 As shown, the air duct air inlet assembly 4 includes an air inlet rear cover 41 and a dual air duct structural member 42. The air inlet rear cover 41 and the dual air duct structural member 42 are connected to form an air duct fusion chamber 14. The air inlet rear cover 41 is provided with a rear cover air inlet hole 411. The rear cover air inlet hole 411 is connected with the air duct fusion chamber 14 to form a first air duct. The dual air duct structural member 42 is provided with a main air inlet duct opening 44 in the middle and an auxiliary air inlet duct opening 45 on the side. The handle air inlet hole 221, the second air inlet 13, the auxiliary air inlet duct opening 45 and the air duct fusion chamber 14 are connected to form a second air duct. The main air inlet duct opening 44 is connected to the air inlet of the high-speed motor 3.

[0033] The airflow from the first air duct directly enters the air duct fusion chamber 14, while the airflow from the second air duct enters the air duct fusion chamber 14 through the secondary air inlet duct opening 45. After the airflow converges, it enters the high-speed motor 3 through the main air inlet duct opening 44. The dual air duct structure 42 provides the hair dryer with dual air inlets, increasing the air intake volume and reducing the wind noise of the intake air.

[0034] An inclined surface is provided on the top of the front shell 51 of the air duct outlet assembly 5, which leaves an air flow channel 15 between the second air inlet 13 and the auxiliary air inlet duct opening 45 of the dual air duct structure 42, so that the air intake airflow of the handle 2 can flow smoothly into the air duct fusion chamber 14.

[0035] The air duct inlet assembly 4 also includes a trapezoidal filter 46. The dual air duct structure 42 is provided with a first filter slot 421. The first filter slot 421 is located at the outer edge of the auxiliary air inlet duct opening 45. The bottom of the trapezoidal filter 46 is connected to the first filter slot 421. The top of the trapezoidal filter 46 is connected to the air inlet rear cover 41. The inclined surface of the air inlet rear cover 41 and the trapezoidal filter 46 form an air inlet buffer zone 43. The air inlet hole 411 of the rear cover is connected to the air inlet buffer zone 43.

[0036] The air intake buffer 43 provides a transition area for the air entering from the air inlet rear cover 41 before entering the filter, widening the air intake duct and preventing the filter from directly contacting the air intake hole, which would narrow the air intake duct and generate wind noise. Furthermore, the air intake buffer 43 also forms an air volume container, ensuring that sufficient air enters the trapezoidal filter 46, ensuring the stability of the air intake volume and improving the operating efficiency of the high-speed motor 3. The trapezoidal filter 46 is preferably made of metal. A metal trapezoidal filter 46 is more resilient, less prone to deformation, and resistant to high temperatures, making it suitable for use in electric hot air blowers.

[0037] The rear cover air intake hole 411 is arranged in a ring shape on the side wall of the air intake rear cover 41. The rear cover air intake hole 411 has a grille-like multi-hole air intake structure. The use of a grille-like multi-hole air intake structure can disperse the incoming airflow as much as possible, dividing the main airflow into multiple small air ducts, thereby dispersing noise. Compared with the problem of loud noise caused by a concentrated airflow, the dispersion of the airflow into multiple small air ducts has a noise reduction effect.

[0038] The air inlet assembly 4 of the air duct also includes a light-emitting assembly 47. A light-emitting slot 412 is provided in the middle of the air inlet rear cover 41. The light-emitting assembly 47 includes a semi-transparent light guide 471, a digital tube 472, and an adapter bracket 473. The semi-transparent light guide 471, the digital tube 472, and the adapter bracket 473 are connected in sequence. The semi-transparent light guide 471 is sealed in the light-emitting slot 412. A second filter slot 474 is provided at the bottom of the semi-transparent light guide 471. The top of the trapezoidal filter 46 is connected to the second filter slot 474.

[0039] The digital tube 472 can display electronic information about the conduit or display decorative lighting effects to enhance the overall appearance of the product. The adapter bracket 473 secures the digital tube 472 to the translucent light guide 471, allowing the display of the digital tube 472 to be seen through the translucent light guide 471. The translucent light guide 471 also acts as a seal around the center of the air intake rear cover 41, preventing air leakage and wind noise from the center.

[0040] like Figure 5 As shown, the handle 2 includes a handle shell 21, an air inlet tail cover 22, a handle filter 23, and a PCB board 24. A handle air duct chamber 25 is provided inside the handle shell 21, and the PCB board 24 is arranged in the handle air duct chamber 25. The air inlet tail cover 22 is provided with a handle air inlet hole 221. The handle filter 23 is connected to one end of the handle shell 21, and the air inlet tail cover 22 is connected to the other end of the inner shell and covers the filter. The other end of the handle shell 21 is connected to the air cylinder shell 11, and the handle air inlet hole 221 is communicated with the handle air duct chamber 25.

[0041] When the handle 2 ends are taking in air, the airflow flows in through the annular handle air inlet hole 221 of the air inlet tail cover 22, and directly enters the handle air duct chamber 25 after being filtered by the handle filter 23, and flows into the air duct fusion chamber 14 along the air duct. The PCB board 24 is located on the air duct of the air flow, and the air flow passing through also plays a role in heat dissipation for the PCB board 24. The handle air inlet hole 221 can adopt a grid-like porous structure to disperse the airflow and reduce wind noise. The handle filter 23 can also adopt a trapezoidal filter 46 such as the air duct air inlet assembly 4, and form an air intake buffer zone 43 between it and the air inlet tail cover 22 to widen the air intake buffer area, to ensure that sufficient wind enters the filter, and to ensure the stability of the air intake volume at the handle 2 ends.

[0042] The handle 2 includes a power cord 27 and a cable fastener 28 . The power cord 27 is used to connect to the PCB board 24 for power supply. The cable fastener 28 fixes the power cord 27 to the handle housing 21 to protect the power cord 27 .

[0043] The handle 2 also includes a silencer net 26, which is disposed within the handle air duct chamber 25. At the air inlet, noise is generated due to the collision of the airflow with the sidewall of the inner shell. Fixing the silencer net 26 at this position can reduce the wind noise at the air inlet of the handle 2.

[0044] like Figure 6 As shown, the air duct outlet assembly 5 includes a front shell 51, a rear shell 52, an air guide 54 with an arc boss 541, a heating wire 55, and an annular bracket 56. The front shell 51 and the rear shell 52 are buckled together to form an air outlet chamber 53. The heating wire 55 is arranged in the annular bracket 56. The air guide 54 is connected in the middle of the annular bracket 56. The heating wire 55 is located at the downwind port of the air guide 54. The rear shell 52 is provided with an annular air outlet position 521. The annular bracket 56 is connected in the air outlet chamber 53. The air outlet position 521 is aligned with the position of the heating wire 55. The front shell 51 is provided with a motor mounting slot 511. The motor mounting slot 511 is connected to the air outlet chamber 53. The high-speed motor 3 is connected in the motor mounting slot 511.

[0045] The air guide 54 is located at the downwind side of the high-speed motor 3. The arc boss 541 structure of the air guide 54 guides the air outlet of the high-speed motor 3 to the two sides, and flows into the annular heating wire 55 for hot air heating, thereby avoiding the formation of turbulence in the middle of the annular bracket 56, making the flow of the air duct smoother and greatly reducing wind noise.

[0046] The air guide 54 is fixed to the mica sheet 561 of the annular bracket 56 via corresponding slots 542, and the outer wall of the annular bracket 56 is also fixed to the interior of the rear shell 52 via corresponding slots. A stop 57 is provided on the lower edge of the front shell 51 and the upper edge of the rear shell 52, with corresponding hooks 571 and slots 572 provided on the stop 57. The stoppers of the front shell 51 and rear shell 52 are offset and docked with each other, and fixedly docked by the hooks 571 and slots 572. The stop 57 can seal the gap at the connection between the front shell 51 and rear shell 52. The front shell 51 and rear shell 52 are both integral parts, connected to the buckle position by a circle of raised stop 57, forming a sealed structure that eliminates the possibility of sound leakage. The heating wire 55 and air guide 54 are inside, greatly reducing the generation of wind noise.

[0047] The heating wires 55 are arranged in a circular pattern, which, combined with the circular air outlet holes 521 on the rear housing 52, disperse and heat the diverted air before delivering it. The entire air duct forms a single outlet surface, making the air softer when it hits the user's head, eliminating the sensation of being directly blown by strong, concentrated wind, and improving the user experience. A decorative ring 58 can be added to the bottom of the rear housing 52 to enhance the aesthetics of the air outlet.

[0048] The high-speed motor 3 can be directly installed into the motor mounting slot 511, and the dual air duct structure 42 is fixed to the motor mounting slot 511 of the front shell 51 by screws, clamping the edge of the high-speed motor 3 to prevent the high-speed motor 3 from falling off from the motor mounting slot 511 while ensuring that the air inlet is not blocked.

[0049] like Figure 7 As shown, the top of the cavity wall of the front shell 51 is higher than the bottom outlet of the motor mounting slot 511, forming an inner groove 512 facing away from the wind direction. The design of the inner groove 512 of the front shell 51 increases the volume of the entire air outlet cavity. The design of the inner groove 512 facing away from the wind direction can serve as a buffer space for airflow. When the air intake is insufficient, the airflow in the inner groove 512 can serve as a supplement, thereby stabilizing the air outlet pressure and reducing the wind noise caused by unstable air pressure and air volume.

[0050] The low-noise, high-pressure high-speed hair dryer also includes a motor buffer pad 31, which is sleeved on the outside of the high-speed motor 3. The outer surface of the motor buffer pad 31 is provided with raised points 32 that increase the roughness. The outer surface of the motor buffer pad 31 is in contact with the inner side of the motor mounting groove 511. The motor buffer pad 31 is assembled between the high-speed motor 3 and the motor mounting groove 511 to act as a buffer, so that the high-speed motor 3 does not directly hit the front housing 51 due to vibration and generate noise during operation. The high-speed motor 3 is protected and also has a noise reduction effect. The raised points 32 on the outer surface of the motor buffer pad 31 can fit more firmly with the inner side of the motor mounting groove 511 to prevent loosening and falling off.

[0051] The working principle of this low-noise, high-pressure high-speed hair dryer is:

[0052] When the high-speed motor 3 is running, a negative pressure is formed in the air duct fusion chamber 14. Air is simultaneously drawn into the air duct inlet assembly 4 and the handle 2 of the air duct fusion chamber 14 to form two air ducts that converge into the air duct fusion chamber 14. Since the airflows in the two air ducts flow in different directions, the noise waves generated by the two airflows when converging will affect each other and partially cancel each other out, thereby achieving a noise reduction effect.

[0053] The air intake process of the first air duct is as follows: the external air flows into the air intake buffer zone 43 between the trapezoidal filter 46 and the air intake rear cover 41 through the annular rear cover air intake hole 411 of the air intake rear cover 41, and a part of the air flow will enter the air duct fusion chamber 14 along the filter holes on the inclined surface of the trapezoidal filter 465, and enter the high-speed motor 3 through the main air intake duct opening 44 of the dual-duct structural member 42. Since the wind direction of the air flow entering the trapezoidal filter 46 is perpendicular to the wind direction of the air flow entering the air intake rear cover 41 or is relatively at a certain angle, the noise sound waves generated by the air flows in the two directions will affect each other and partially offset each other, thereby achieving the effect of reducing wind noise; the other part of the air flow will be temporarily cached in the air intake buffer zone 43 as a supplement to the air volume to ensure the stability of the air intake volume. Even if the air flow flowing in from the air intake rear cover 41 suddenly decreases, the air flow in the air intake buffer zone 43 can also be used as a supplementary intake without immediately affecting the air intake volume at the end of the air duct inlet assembly 4.

[0054] The air intake process of the second air duct: the external airflow will flow in from the annular handle air inlet hole 221 of the air inlet tail cover 224, and after being filtered by the handle filter 23, it will enter the handle air duct chamber 25 and flow along the handle air duct chamber 25 into the second air inlet 13 of the air duct 1. The airflow will then enter the air duct fusion chamber 14 from the secondary air inlet duct opening 45 of the dual air duct structure 42, and merge with the airflow of the first air duct. During this process, the airflow flowing through the handle air duct chamber 25 will cool the PCB board 24, and at the same time, the noise of the airflow flowing into the air duct chamber will be reduced by the silencer 26, thereby ensuring that the air is taken in by the handle 2 ends while also achieving a low noise effect.

[0055] The air duct fusion chamber 14 is transported to the air outlet chamber 53 through the rotation of the high-speed motor 3, and is guided by the arc boss 541 of the air guide 54, so that the air duct coming out of the high-speed motor 3 is divided into multiple side air ducts and enters the annular heating slot. The wind is heated by the heating wire 55 and blown out from the annular air outlet position 521 of the rear shell 52. The setting of the arc boss 541 of the air guide 54 guides the air outlet of the high-speed motor 3 smoothly to the heating wire 55, and will not form turbulence in the middle of the heating slot to emit noise, thereby playing a role in noise reduction. At the same time, part of the air volume of the high-speed motor 3 will be cached at the inner groove position 512 of the front shell 51, so that the entire air outlet chamber 53 becomes a space filled with airflow. When the air intake is sufficient, the wind will be directly heated by the heating wire 55 and blown out directly. When the air intake suddenly decreases, the air flow in the inner groove position 512 can be merged with the air intake and blown out after heating. Therefore, the air outlet component 5 end of the air duct ensures the stability of the air volume and pressure of the air outlet, so as to avoid the problem of fluctuating air volume, reduce the noise impact of unstable air volume at the air outlet, and improve the user experience.

[0056] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
