Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, and in particular to a hair dryer with a large air intake. Background Technology

[0002] With the fast pace of modern life, people want to dry their hair quickly, especially women with long hair and those with thick hair. Hair dryers with a large air intake can generate stronger airflow, thereby accelerating the evaporation of moisture from the hair surface and achieving fast drying, thus meeting people's demand for efficient hair drying.

[0003] Existing technologies, such as the utility model patent with publication number CN210203741U, disclose a hair dryer with a large air intake. This patent uses a protrusion with several through first air inlets on its axial outer wall and a through second air inlet on its circumferential outer wall. This results in a larger air intake and better performance, solving the problem that most current hair dryers only have one end face for air intake, resulting in a small air intake and mediocre performance.

[0004] In daily life, when using hair dryers, as mentioned above, users need to hold them during use. After use, when the hair dryer is placed somewhere, the air inlet may accumulate dust due to prolonged storage. This dust can then enter the hair dryer's body, potentially causing the bearings to wear more quickly due to friction with the dust, reducing the motor's rotational precision, or even causing it to jam, thus shortening the hair dryer's lifespan. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing hair dryers where, due to prolonged storage, dust accumulates in the air inlet and enters the hair dryer body. This dust can cause the bearings to wear more quickly during use, leading to decreased motor rotation accuracy and even jamming, thus reducing the lifespan of the hair dryer. The invention proposes a hair dryer with a larger air intake capacity.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a hair dryer with a large air intake capacity, comprising a cylinder, an air inlet, and a placement component. One end of the cylinder is provided with an air inlet, and the end of the cylinder away from the air inlet is provided with an air outlet. A handle is provided on the outer arc surface of the cylinder, and a placement component is provided on the outer arc surface of the handle. The placement component includes a clamping block, which is in contact with the outer arc surface of the handle. A linkage rod is fixedly connected to one side of the clamping block, and a mounting block is in contact with the side of the clamping block near the linkage rod. A positioning block is fixedly connected to one side of the mounting block, and a bidirectional lead screw is rotatably connected to the side surface of the positioning block. A knob is fixedly connected to the end of the bidirectional lead screw away from the positioning block, and a linkage rod is threadedly connected to the surface of the bidirectional lead screw. A suction cup is installed on the side of the mounting block away from the clamping block.

[0007] Preferably, the inner surface of the clamping block is arc-shaped, and there are two clamping blocks arranged symmetrically about the handle. Through the cooperation of the clamping block linkage rod, the position of the cylinder can be supported to ensure the stability of the cylinder when placed.

[0008] Preferably, the surface of the mounting block is provided with a mounting groove, the mounting block is rectangular, and the mounting block contacts one side of the knob. Through the cooperation of the mounting block and the bidirectional lead screw, the linkage rod can be moved to ensure that the distance can be adjusted according to the cylinder of different sizes.

[0009] Preferably, the suction cup is in contact with the front surface when in use. The suction cup can firmly attach the mounting block to the front surface, making it convenient to remove when using the hair dryer.

[0010] Preferably, the upper surface of the mounting block is provided with a dustproof component, which includes a guide plate. The guide plate is fixedly connected to the upper surface of the mounting block, and a first linkage block is fixedly connected to the upper surface of the mounting block. A rotating gear is rotatably connected to the arc surface of the first linkage block, and a rotating shaft is fixedly connected to the upper surface of the rotating gear. A second linkage block is fixedly connected to the upper surface of the mounting block, and a linkage gear is rotatably connected to the arc surface of the second linkage block. A rotating lead screw is fixedly connected to the upper surface of the linkage gear, and a threaded sleeve is threadedly connected to the outer surface of the rotating lead screw. A linkage plate is fixedly connected to the outer surface of the threaded sleeve, and a cover is fixedly connected to the side surface of the linkage plate. Through the cooperation of the guide plate and the cover, the direction of movement of the linkage plate can be guided to ensure that the linkage plate can move in the direction of the guide plate.

[0011] Preferably, the rotating gear meshes with the tooth groove of the linkage gear. Through the cooperation between the rotating gear and the first linkage block, the linkage gear can be driven to rotate, so that when the operator rotates the rotating shaft, the rotating screw can be driven to rotate.

[0012] Preferably, the shield is arranged in an N-shape, the shield is in contact with the surface of the air inlet, the shield is in contact with the surface of the guide plate, and the shield is in contact with the upper surface of the mounting block. Through the cooperation of the shield and the linkage plate, it can move downward along the rotating screw to ensure that the air inlet and outlet can be protected.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a placement component, when the user needs to use a hair dryer to dry their hair, they can hold the handle, turn on the hair dryer, and then aim the air outlet at their hair to begin drying. When placing the hair dryer for the first time, first align the suction cup with the wall where the plug is located, and then firmly attach it to the wall. Then, the user first holds the knob with one hand and turns the knob clockwise. As the knob turns, it drives the bidirectional lead screw to rotate. As the bidirectional lead screw rotates, it engages with the toothed groove of the linkage rod. Then, under the action of the linkage rod, the clamping block moves along the bidirectional lead screw towards the handle. Once it moves close to the handle and clamps it, the user can stop turning the knob, thus restricting the position of the handle. By setting up a placement component, the position of the hair dryer can be effectively supported, avoiding the need for the user to search for the hair dryer when needed, reducing time. When adjusting the hair, the hair dryer can be easily placed down without worrying about it falling, further improving the flexibility of use.

[0015] 2. In this utility model, by setting up a placement component, after using the hair dryer, the user can hold the rotating shaft with one hand and rotate it clockwise. Simultaneously, the rotating shaft drives the rotating gear to rotate. The rotating gear meshes with the teeth of the linkage gear, which in turn drives the linkage gear to rotate. The linkage gear, in turn, drives the rotating screw to rotate. Simultaneously, the rotating screw meshes with the threaded sleeve, causing the threaded sleeve to move towards the mounting block. At the same time, the threaded sleeve moves the linkage plate downwards, causing the linkage plate to move downwards along the guide rod. During this movement, the cover contacts the air inlet and gradually completely covers it. The rotation of the rotating shaft can then be stopped, thus protecting the air inlet. By setting up a dustproof component, dust can be effectively protected from the air inlet, preventing dust from entering the cylinder when the blower is not in use. This also reduces dust wear on the motor, further extending the motor's service life. Attached Figure Description

[0028] Specifically, the inner surface of the clamping block 51 is arc-shaped, and there are two clamping blocks 51, which are arranged symmetrically about the handle 4.

[0029] The effect achieved by the above components is that, through the cooperation of the clamping block 51 and the linkage rod 52, the position of the cylinder 1 can be supported to ensure the stability of the cylinder 1 when it is placed.

[0030] Specifically, the surface of the mounting block 53 is provided with a mounting groove, the mounting block 53 is rectangular, and the mounting block 53 is in contact with one side of the knob 56.

[0031] The effect achieved by the above components is that, through the cooperation of the mounting block 53 and the bidirectional lead screw 55, the linkage rod 52 can be moved to ensure that the distance can be adjusted according to the different sizes of the cylinder 1.

[0032] Specifically, suction cup 57 is in contact with the phase surface when in use.

[0033] The effect achieved by the above components is that the mounting block 53 can be firmly attached to the front by the suction cup 57, making it convenient to remove when using the hair dryer.

[0034] Specifically, a dustproof component 6 is provided on the upper surface of the mounting block 53. The dustproof component 6 includes a guide plate 61. The guide plate 61 is fixedly connected to the upper surface of the mounting block 53. A first linkage block 62 is fixedly connected to the upper surface of the mounting block 53. A rotating gear 63 is rotatably connected to the arc surface of the first linkage block 62. A rotating shaft 64 is fixedly connected to the upper surface of the rotating gear 63. A second linkage block 65 is fixedly connected to the upper surface of the mounting block 53. A linkage gear 66 is rotatably connected to the arc surface of the second linkage block 65.

[0040] Working principle: When the user needs to use the hair dryer to dry their hair, they hold the handle 4, turn on the hair dryer, and then point the air outlet 3 at the hair to start drying. When placing the hair dryer for the first time, first align the suction cup 57 with the wall of the plug plate and then firmly attach it to the wall. Then, the user first holds the knob 56 with one hand and turns the knob 56 clockwise. As the knob 56 turns, it drives the bidirectional lead screw 55 to rotate. As the bidirectional lead screw 55 rotates, it engages with the tooth groove of the linkage rod 52. Then, under the action of the linkage rod 52, the clamp 51 moves along the bidirectional lead screw 55 towards the handle 4. After moving close to the handle 4 and clamping the handle 4, the user can stop turning the knob 56 and thus restrict the position of the handle 4. By setting the placement component 5, the position of the hair dryer can be effectively supported, avoiding the need for the user to search for the hair dryer when needed, reducing time. When the user needs to adjust their hair, they can easily put down the hair dryer without worrying about it falling, further improving the flexibility of use.

[0041] Additionally, by setting up placement component 5, after using the hair dryer, the user can hold the rotating shaft 64 with one hand and rotate it clockwise. Simultaneously, the rotating shaft 64 drives the rotating gear 63 to rotate. The rotating gear 63 meshes with the teeth of the linkage gear 66, which in turn drives the linkage gear 66 to rotate. The linkage gear 66 then drives the rotating screw 67 to rotate, which in turn meshes with the threaded sleeve 68, causing the threaded sleeve 68 to move towards the mounting block 53. When moving, the linkage plate 69 moves downward synchronously. As the linkage plate 69 moves, the shield 610 moves downward along the direction of the guide rod. During the movement, it comes into contact with the air inlet 2 and gradually covers the air inlet 2 completely. Then the rotating shaft 64 stops rotating, thus completing the protection of the air inlet 2. By setting the dustproof component 6, the air inlet 2 can be effectively protected from dust, preventing dust from entering the cylinder 1 from the air inlet 2 when the exhaust fan is not in use. At the same time, it reduces the wear of the motor by dust, thereby further extending the service life of the motor.
