Description

Technical Field

[0001] This utility model relates to a hair dryer with an adjustable air outlet. Background Technology

[0002] Portable handheld hair dryers are popular for home care and commercial environment beautification. Common handheld hair dryers are powered by gasoline engines or electric motors. The hair dryer housing contains a fan that is driven by the power source to rotate inside the hair dryer housing, generating airflow that is discharged outward through the housing's outlet.

[0003] To enhance user experience, hair dryers need to be able to adjust the speed and pressure of the exhaust airflow in different working environments. Many existing hair dryers change the airflow speed and pressure at the outlet by altering the fan speed. However, this method has certain drawbacks. When a higher fan speed is needed, more electricity or fuel is required, leading to increased overall energy consumption. Especially in battery-powered portable hair dryers, higher energy consumption can significantly shorten the device's operating time. Additionally, higher fan speeds usually mean that the motor or engine needs to work harder, generating more heat. If the heat dissipation design is poor, this can lead to overheating problems, affecting the device's lifespan and performance. Some hair dryers adjust the airflow by providing multiple replaceable nozzles, each with an air outlet of a different diameter. However, this method requires manual nozzle replacement, which is cumbersome. Utility Model Content

[0037] (Example 1)

[0038] See Figure 1-7 The adjustable air blower of this embodiment includes a housing 1 and an air outlet adjustment device. The housing 1 is equipped with a fan. The air outlet adjustment device includes an air outlet adjustment pipe 3, an adjustment ring 4 and multiple blades 5. One end of the air outlet adjustment pipe 3 is connected to the housing 1, and the other end is connected to multiple blades 5. The adjustment ring 4 is slidably connected to the adjustment pipe along the axial direction of the adjustment pipe. When the adjustment ring 4 moves along the axial direction of the air outlet adjustment pipe 3, it adjusts the closing and opening of the blades 5.

[0039] Specifically, the adjusting ring 4 is provided with a locking device 6, which includes a button and a button groove provided on the air outlet adjusting pipe 3; when the button is pressed, the button can slide in the button groove to make the adjusting ring 4 move axially along the air outlet adjusting pipe 3.

[0040] The blade 5 includes a blade body 5-1, a blade rotating part 5-2, and a blade support part 5-3. The blade body 5-1 and the blade support part 5-3 are respectively arranged on both sides of the blade rotating part 5-2. The adjusting ring 4 includes a groove 4-2 with one side open. The blade support part 5-3 is embedded in the groove 4-2. The blade 5 is fixed relative to the groove 4-2.

[0041] A bushing 3-2 is provided on the air outlet regulating pipe 3. The blade rotating part 5-2 is hollow inside. The bushing 3-2 and the blade rotating part 5-2 are spaced apart. A rotating shaft is provided in the bushing 3-2 and the blade rotating part 5-2. When the regulating ring 4 moves along the axial direction of the air outlet regulating pipe 3, it drives the blade 5 to rotate around the rotating shaft. In this embodiment, the regulating ring 4 is provided with an regulating ring fixing part 4-1 along the moving direction. The air outlet regulating pipe 3 is provided with a fixing groove 3-1 that cooperates with the regulating ring fixing part 4-1. One of the fixing grooves 3-1 is opened on the bushing 3-2. The cooperation between the regulating ring fixing part 4-1 and the fixing groove 3-1 prevents the regulating ring 4 from shaking around the circumference of the air outlet regulating pipe 3. Of course, a sliding groove can also be opened on the regulating ring 4, and a sliding rail can be provided on the air outlet regulating pipe 3. The same effect can be achieved by the cooperation between the sliding rail and the sliding groove.

[0042] A first protrusion 4-2-1 is provided on the inner sidewall of the groove 4-2. The blade support part 5-3 includes a first support rod 5-3-1 and a second support rod 5-3-2, and the first protrusion 4-2-1 and the first support rod 5-3-1 cooperate with each other. A second protrusion 4-2-2 is provided inside the groove 4-2, and the second protrusion 4-2-2 and the second support rod 5-3-2 cooperate with each other. The first protrusion 4-2-1 is close to the opening of the groove 4-2, and the second protrusion 4-2-2 is close to the bottom of the groove 4-2. The second protrusion 4-2-2 in the groove 4-2 is located at the bottom of the groove 4-2, and its width is equivalent to the size of the second support rod 5-3-2. When the blade 5 is in the retracted state, the blade support part 5-3 is located at the bottom of the groove 4-2. One side of the second support rod 5-3-2 abuts against the second protrusion 4-2-2, and the other side abuts against the inner sidewall of the groove 4-2, so that the blade support part 5-3 is stuck in the groove 4-2. At this time, the blade 5 and the adjusting ring 4 are relatively fixed. As the adjusting ring 4 moves axially along the air outlet adjusting pipe 3, the blade support 5-3 gradually disengages from the bottom of the groove 4-2. The second support rod 5-3-2 is offset from the second protrusion 4-2-2, while the first support rod 5-3-1 abuts against the first protrusion 4-2-1. The blade 5 rotates around the axis in the blade rotating part 5-2 under force. When the blade 5 is in the open state, the first support rod 5-3-1 abuts against the first protrusion 4-2-1, and the second support rod 5-3-2 abuts against the inner wall of the groove 4-2. At this time, the blade 5 and the adjusting ring 4 are relatively fixed. As a preferred embodiment, both the first protrusion 4-2-1 and the second protrusion 4-2-2 are provided with inclined surfaces to facilitate the change of the blade 5 between the open and closed states.

[0043] The blade 5 at least partially covers the end of the air outlet regulating pipe 3. The blade 5 includes alternating first blades 51 and second blades 52, with the two wings of the first blade 51 overlapping the adjacent second blade 52; when the blade 5 is in the retracted state, the inner ring of the blade 5 forms a ring surface and cooperates with the inner sidewall of the air outlet regulating pipe 3. The blade 5 arrangement in this embodiment allows the blade 5 to maintain good closure and opening in different states, ensuring both concentrated airflow and convenient large-area air supply, while reducing noise during the air supply process.

[0044] This invention controls the blades 5 to close and open by adjusting the ring 4 along the axial direction of the air outlet adjusting pipe 3. The size of the air outlet can be adjusted as needed, thereby controlling the air distribution and concentration, and improving the flexibility and applicability of the blower.

[0045] (Example 2)

[0046] The difference between this embodiment and Embodiment 1 is that it also includes an extension tube 2. One end of the extension tube 2 is connected to the housing 1, and the other end is connected to the air outlet regulating tube 3. In this embodiment, the extension tube 2 is detachably connected to the housing 1, and the air outlet regulating tube 3 is detachably connected to the extension tube 2. The connection structure between the extension tube 2 and the housing 1, and between the air outlet regulating tube 3 and the extension tube 2, is consistent, which facilitates cleaning and maintenance. At the same time, users can replace parts of different lengths or types according to actual needs, increasing the flexibility and adaptability of the product, while also facilitating transportation and storage, and improving the overall user experience.

[0047] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model.
