Description

Technical Field

[0001] This utility model relates to the field of garden equipment technology, and in particular to a hair dryer. Background Technology

[0002] Currently, in the field of garden maintenance, hair dryers are commonly used for cleaning fallen leaves and debris, and their structural rationality directly affects work efficiency and user experience. To facilitate user grip, hair dryers often employ a D-shaped handle with a longitudinal cross-section in their structural design. While this handle combines aesthetics and grip comfort, in actual design, to balance the device's center of gravity and improve space utilization, the assembled battery usually needs to be directly coupled to the bottom or rear of the handle. However, the space below and at the rear of the D-shaped handle is inherently limited to ensure grip comfort, resulting in poor compatibility of the hair dryer with battery pack sizes.

[0003] No effective solution has yet been proposed to address the above problems. Utility Model Content

The hair dryer further includes a first protrusion and a second protrusion. The air duct assembly further includes an air pipe and a connecting portion. The air pipe is connected to the first protrusion and the second protrusion respectively through the connecting portion. The air outlet is located at the end of the air pipe away from the connecting portion, and the air inlet is located at the end of the connecting portion away from the air pipe. The first protrusion and the second protrusion are respectively located on both sides of a central plane. The first protrusion is used for electrically connecting to the battery pack, and the second protrusion is used for gripping. The central plane is a horizontal plane including a central axis.

[0006] Optionally, a support structure is provided at the bottom of the first protrusion to provide support when the hair dryer is placed.

[0007] Optionally, the fan is located inside the connector, and the motor is located at the connection between the connector and the duct.

[0008] Optionally, a guide pipe is installed inside the duct.

[0009] Optionally, a protective grille is also installed inside the duct, located on the side of the guide duct near the air outlet.

[0022] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These embodiments should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0023] Reference Figures 1-3 In one embodiment of the present invention, the hair dryer includes: a motor 1 for driving a fan 2 to rotate around a central axis; the fan 2 for generating airflow; a battery pack 3; and an air duct assembly 4 including an air inlet 41 and an air outlet 42 located at opposite ends of the air duct assembly 4. The hair dryer also includes a first protrusion 5 and a first protrusion 6. The air duct assembly 4 also includes an air pipe 43 and a connecting portion 44. The air pipe 43 is connected to the first protrusion 5 and the first protrusion 6 respectively through the connecting portion 44. The air outlet 42 is located at the end of the air pipe 43 away from the connecting portion 44, and the air inlet 41 is located at the end of the connecting portion 44 away from the air pipe 43. The first protrusion 5 and the first protrusion 6 are located on both sides of a central plane. The first protrusion 5 is used for electrically connecting to the battery, and the first protrusion 6 is used for gripping. The central plane is a horizontal plane including a central axis.

[0024] Specifically, the diameter of the inlet 41 is smaller than the diameter of the air inlet 41 at the junction of the connecting part 44 and the air duct 43. A first protrusion 5 extends directly from the bottom of the connecting part, and a pin is provided at the upper end of the first protrusion 5 for connecting the battery pack 3. It should be noted that this pin is a universal pin. The first protrusion 6 extends from the top of the connecting part 44 and can be used for gripping. The central axis surface can be a horizontal plane parallel to the placement plane when the hair dryer holder is placed alone.

[0025] Optionally, a protective cover 433 may be installed at the aforementioned air inlet 41.

[0026] In an optional embodiment, the first protrusion 6 includes a bent portion 61 and a grip structure 62. The bent portion 61 extends from above the connecting portion 44 and connects to the grip portion, and the grip structure 62 is a curved rod-shaped handle. A switch 621 is provided below the connection between the rod-shaped handle and the bent portion 61, allowing the user to press the switch 621 while holding the hair dryer. A rapid-fire button 612 is also provided above the bent portion 61, which allows the hair dryer to quickly increase its blowing efficiency when pressed. A speed adjustment button 611 is provided on the side of the bent portion 61, allowing the user to adjust the rotation angle and thus the speed setting of the hair dryer by toggling the speed adjustment button 611.

[0027] In an alternative embodiment, the aforementioned air duct and connecting part 44 can be an integral structure or they can be spliced ​​together.

[0028] Optionally, the battery pack 3 is detachably mounted on the first protrusion 5.

[0029] In an optional embodiment, a limiting device that cooperates with the battery pack 3 may be provided above the first protrusion 5, such as a quick-release pin and positioning post, or a slider and guide rail / slide groove.

[0030] It should be noted that the hair dryer provided by this utility model has its grip and base evenly distributed on both sides of the central axis, optimizing the central distribution and maintaining balance even without the battery pack 3 installed. Secondly, when the installed battery pack 3 is a suitable size, its center is very close to or located on the central axis of the hair dryer, resulting in a more uniform weight distribution. This reduces the eccentric torque during operation, minimizing wrist and arm fatigue during prolonged holding or adjusting the blowing angle, making operation more effortless. Thirdly, compared to a D-shaped handle, the rod-shaped handle used in this utility model reduces production costs and offers better economic benefits.

[0031] In an optional embodiment, a connecting piece may be provided on the side of the connecting portion 44 between it and the first protrusion 5 to reinforce the structure.

[0032] Optionally, the bottom of the first protrusion 5 is provided with a support structure to provide support when the hair dryer is placed.

[0033] Specifically, the aforementioned support structure can be a flat base, a suction cup base, or a support column base. When the support structure is a flat base, the surface of the flat structure can be treated with a certain anti-slip treatment to increase friction and improve stability; for example, by adding rubber pads or textures.

[0034] The aforementioned battery pack 3 can be of the following types: lithium-ion battery pack, lead-acid battery pack, nickel-metal hydride battery pack, hydrogen fuel cell pack, sodium-sulfur battery pack, and solar cell pack. This invention does not limit the type of battery pack, as long as it can provide power to meet the power requirements of the hair dryer.

[0035] In the above embodiments of this utility model, by directly and respectively setting the first protrusion 5 for electrically connecting the battery pack 3 and the first protrusion 6 for gripping on both sides of the central plane, the first protrusion 5 and the first protrusion 6 are connected through the connecting part 44, and the battery pack 3 is no longer directly connected to the first protrusion 6 for gripping. This reduces the influence of the space limitation below or behind the handle on the size of the battery pack, and achieves the technical effect of improving the compatibility of the hair dryer with the battery pack size.

[0036] Optionally, the fan 2 is located inside the connecting part 44, and the motor is located at the connection between the connecting part 44 and the air duct 43.

[0037] Optionally, a guide pipe 431 is provided inside the air duct 43.

[0038] Specifically, the aforementioned guide tube 431 can be cylindrical or conical, and is fitted onto the outside of the motor 1.

[0039] Optionally, a protective grille 432 is also provided inside the air duct 43, and the protective grille 432 is located on the side of the guide pipe 431 near the air outlet 42.

[0040] Specifically, the protective grille 432 can be made of alloy or plastic, preferably alloy, to prevent foreign objects from falling into the depths of the air duct and to protect the motor 1 and the fan 2.

[0041] Optionally, the first protrusion 6 includes a bend 61, a gear shift button 611 is provided on the side of the bend 61, and a speed button 612 is provided on the top of the bend 61.

[0042] Specifically, the aforementioned rapid button 612 is used to control the hair dryer to instantly increase its power, and its surface may be provided with graphic prompts.

[0043] Optionally, the guide tube 431 is conical.

[0044] Specifically, the conical airflow guide tube in the hair dryer can smoothly accelerate the airflow through a gradual change in cross-section, enhance the concentration of airflow, reduce turbulence and noise, and improve the drying efficiency and user experience.

[0045] Optionally, the bottom surface of the supporting structure is a plane.

[0046] Specifically, when the bottom surface is flat, the force on the bottom surface of the hair dryer is more even, which helps to increase the stability of the hair dryer.

[0047] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
