Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, specifically to a hair dryer with noise reduction function. Background Technology

[0002] Hair dryers are primarily used for drying and styling hair, but they can also be used in laboratories, physiotherapy rooms, industrial production, and art applications for localized drying, heating, and therapeutic purposes. A hair dryer works by an electric motor driving a rotor that rotates the fan blades. As the blades rotate, air is drawn in through the inlet, and the resulting centrifugal airflow is then blown out through the nozzle. If the heating element on the heating bracket in the nozzle is energized and heated, hot air will be blown out; if the switch prevents the heating element from heating, cold air will be blown out.

[0003] For example, Chinese patent CN217999978U discloses a hair dryer with noise reduction function, including a hair dryer body, a connector fixedly connected to the top of the hair dryer body, a first mounting box threadedly connected to the top of the connector, a second mounting box threadedly connected to the bottom of the hair dryer body, sound insulation cotton fixedly installed on the inner side wall of the hair dryer body, shock-absorbing springs fixedly connected to both inner sides of the hair dryer body, and a servo motor fixedly connected to the top of the shock-absorbing springs.

[0004] However, the noise of a hair dryer mainly comes from the sound of the motor and blades rotating.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0033] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0034] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6A hair dryer with noise reduction function includes a bladeless hair dryer body 1. The bladeless hair dryer body 1 includes a hair dryer handle 11, an annular housing 12, and an air inlet 13. The top of the hair dryer handle 11 is fixedly connected to and communicates with the bottom side of the annular outer wall of the annular housing 12. Multiple sets of air inlets 13 are opened at intervals on the side wall of the hair dryer handle 11. A motor 2 is fixedly installed inside the hair dryer handle 11. An impeller 4 is fixedly connected to the output end of the motor 2. An electric heating component 3 is provided above the impeller 4. The electric heating component 3 is fixedly installed on the annular inner wall of the annular housing 12. Noise reduction components 5 for reducing noise are installed on the inner wall of the hair dryer handle 11 and the inner wall of the annular housing 12.

[0035] The left end of the ring housing 12 is provided with a clamping adjustment mechanism 6 for clamping hair. The clamping adjustment mechanism 6 includes a fixing component 61 and an adjustment component 62. The adjustment component 62 is mounted on the fixing component 61, and the fixing component 61 is threadedly connected to the left end of the ring housing 12.

[0036] In use, this invention employs a bladeless hair dryer, eliminating the need for blades inside the annular housing 12 and avoiding noise generated by blades during operation. Furthermore, a noise reduction component 5 is installed on the outside of the motor 2 to reduce noise generated during operation. The same component 5 is also installed on the inner wall of the annular housing 12 to reduce noise when the air generated by the motor 2 driving the impeller 4 collides with the inner wall of the annular housing 12, thus achieving noise reduction for the hair dryer. Additionally, this invention adds a fixing component 61 and an adjusting component 62. The fixing component 61 drives the adjusting component 62 to clamp the hair, ensuring that hot air dries the hair continuously inside the annular housing 12 during drying, guaranteeing efficient hair drying.

[0037] Example 2: In some embodiments, such as Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment of the present invention, the electric heating component 3 adopts the mature existing technology in the field. The electric heating component 3 consists of multiple infrared heating tubes, which are installed on the annular inner wall of the annular housing 12.

[0038] The noise reduction component 5 includes a first sound insulation cotton 51 and a second sound insulation cotton 52, both of which have small holes for gas to pass through. Both the first sound insulation cotton 51 and the second sound insulation cotton 52 are made of silicone, rubber, or sponge.

[0039] The first sound insulation cotton 51 is fixedly installed on the inner wall of the hair dryer handle 11, and the first sound insulation cotton 51 wraps around the outside of the motor 2 to reduce the noise of the motor 2 during operation. The second sound insulation cotton 52 is fixedly installed on the annular inner wall of the annular housing 12, and the second sound insulation cotton 52 is located inside the heating element 3.

[0040] When in use, the hair dryer is turned on by switching on the switch and adjusting it to hot air start. The infrared heating tube starts heating, the motor 2 starts, and the motor 2 drives the impeller 4 to rotate. The impeller 4 absorbs the airflow from the outside through the air inlet 13. After being heated by the infrared heating tube, the airflow is blown into the interior of the annular housing 12. Then, the air outlet of the annular housing 12 is aimed at the hair to dry it. The first sound insulation cotton 51 absorbs the noise generated by the motor 2, and the second sound insulation cotton 52 absorbs the noise generated by the wind generated by the impeller 4 when it collides with the inner wall of the annular housing 12, thereby achieving noise reduction of the hair dryer.

[0041] Example 3: In some embodiments, such as Figure 3 , Figure 4 and Figure 6 As shown, in a preferred embodiment of the present invention, the fixing component 61 includes an outer cover 611, an arc-shaped groove 612, a sliding ring 613, and a sliding block 614. The outer cover 611 has a through arc-shaped groove 612 in the middle of its annular outer wall. The sliding block 614 is provided inside the arc-shaped groove 612 and is slidably connected to the arc-shaped groove 612. The sliding ring 613 is sleeved on the annular outer wall of the outer cover 611 and is rotatably slidably connected to the annular outer wall of the outer cover 611. The outer end of the sliding block 614 is fixedly connected to the inner side of the sliding ring 613.

[0042] The inner end of the sliding block 614 is connected to the adjusting component 62. The adjusting component 62 is installed on the inner wall of the outer cover 611. An air vent is provided in the middle of the left side of the outer cover 611 for inserting and placing single clumps of hair. The inner wall of the right end of the outer cover 611 is provided with an internal thread, and the outer wall of the left end of the annular housing 12 is provided with an external thread. The right end of the outer cover 611 is threadedly connected to the left end of the annular housing 12.

[0043] The adjustment assembly 62 includes a rotating ring 621, a polygonal slot 622, a fixing frame 623, a sliding groove 624, a sliding column 625, and a polygonal block 626. The fixing frame 623 and the rotating ring 621 are arranged sequentially from left to right inside the outer cover 611. The annular outer wall of the rotating ring 621 is slidably connected to the inner wall of the outer cover 611, and the annular outer wall of the rotating ring 621 is fixedly connected to the inner end of the sliding block 614. A polygonal slot 622 is provided on the left side of the rotating ring 621. The outer side wall of the fixing frame 623 is connected to the annular inner wall of the outer cover 611. The wall is fixedly connected, and the fixed frame 623 has multiple through sliding grooves 624 at equal intervals. Multiple polygonal blocks 626 are provided, and the left ends of the multiple polygonal blocks 626 are all slidably connected to the fixed frame 323. The right sides of the multiple polygonal blocks 626 are all slidably connected to the rotating ring 621. Multiple sliding columns 625 are provided and fixedly installed on the left and right sides of the multiple polygonal blocks 626 respectively. The multiple sliding columns 625 on the left are inserted into the multiple sliding grooves 624 for limiting and sliding connection, and the sliding columns 625 on the right are inserted into the polygonal slots 622 for sliding connection.

[0044] In use, the multiple polygonal blocks 626 are initially dispersed. If a single clump of hair needs to be dried, an outer cover 611 can be installed on the left end of the annular housing 12. The single clump of hair is then placed into the annular housing 12 through the outer cover 611. The sliding ring 613 is rotated by hand, which drives the sliding block 614 to rotate. The sliding block 614 drives the rotating ring 621 to rotate, and the polygonal slot 622 rotates accordingly. The polygonal slot 622 drives the polygonal block 626 to rotate, and the polygonal block 626 drives the sliding column 625 on the left side to slide in the sliding groove 624. This causes the multiple polygonal blocks 626 to converge from the periphery to the center, thus clamping the hair. During the blow-drying process, the hot air is always inside the annular housing 12 to dry the hair, ensuring the efficiency of hair drying.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
