Embodiments for Carrying out the Invention

[0018] Hereinafter, the technical solutions included in the embodiments of the present invention will be clearly and completely described. It should be noted that the embodiments described here are only some of the embodiments of the present invention and do not cover all the embodiments. All other embodiments that can be obtained by those skilled in the art without creative labor based on the embodiments of the present invention belong to the protection scope of the present invention.

[0019] Please refer to FIGS. 1 to 8. The high-speed electric air duster with a rotatable body capable of side intake includes a main body 1 and a battery part 2. A motor 3 is installed inside the main body 1, and the motor 3 is electrically connected to the battery part 2 through a wire. The battery part 2 supplies power to the motor 3. A side air intake port 4 is provided on the outer peripheral surface of the main body 1, and the main body 1 and the battery part 2 are rotatably connected. When the main body 1 and the battery part 2 rotate relative to each other, they form an angle, and this angle can reach 90°.

[0020] In a preferred embodiment, the main body 1 includes a main body frame 5, and the motor 3 is installed inside the main body frame 5. An exhaust cover 6 is provided at one end of the main body frame 5, and an intake cover 7 is provided at the other end. The side air intake port 4 is located on the side wall of the intake cover 7, communicates with the inside of the intake cover 7 and the inside of the main body frame 5, and the inside of the exhaust cover 6 also communicates with the inside of the main body frame 5.

[0021] A filter (not shown) is installed inside the intake cover 7 to filter dust and foreign objects inhaled from the side intake port 4. The filter portion corresponding to the side intake port 4 is formed in a concave shape on the inside. Even when foreign objects such as leaves and plastic bags are strongly sucked into the intake cover 7, since the filter and the side intake port 4 are not on the same plane, it is difficult for these foreign objects to block the entire concave filter, and a partial intake path is maintained. As a result, continuous intake is possible, and the protection of the motor part is also achieved.

[0022] Different from the conventional front-back direction intake method, since the side intake rotatable high-speed electric air duster of the present invention adopts a side intake method, the rotational connection between the main body 1 and the battery part 2 can be easily realized.

[0023] In a preferred embodiment, a connection frame body 8 is provided at one end of the battery part 2, and the battery part 2 is detachably attached to the connection frame body 8. One end face of the connection frame body 8 forms a first inclined surface 9, and a rotating shaft 10 is installed on the first inclined surface 9 at an inclination angle of 45°. A second inclined surface 11 is provided at one end of the intake cover 7, and the second inclined surface 11 is aligned parallel to the first inclined surface 9. A rotation bearing 12 is installed on the second inclined surface 11, and a rotation shaft hole 13 is inclinedly installed in the rotation bearing 12, and the rotation shaft hole 13 fits with the rotating shaft 10. The rotating shaft 10 is rotatably inserted into the rotation shaft hole 13.

[0024] Due to the second inclined surface​​​A button knob 23 and a button slider 24 are installed on the connecting frame 8, and the button knob 23 is fixedly connected to the button slider 24. A spring 25 is placed between one end of the button slider 24 and one end of the battery section, and two pillars (not shown) that protrude axially are provided at the other end of the button slider 24. Two shaft holes are provided on the second inclined surface 11 of the intake cover 7, and the two pillars correspond to the two shaft holes. When the two pillars are inserted into the two shaft holes, the relative rotation of the main unit 1 and the battery section 2 is restrained.

[0026] In another preferred embodiment, the inclination angles of the first inclined surface 9 and the second inclined surface 11 are set in the range of 30° to 45°.

[0027] In a preferred embodiment, the exhaust-side end of the motor 3 is positioned close to the exhaust cover 6, and a flow straightening cover 14 is installed on the exhaust-side end of the motor 3. The flow straightening cover 14 is a conical cover body, with one end having a larger diameter attached to the exhaust-side end of the motor 3, and a circular ventilation hole 15 provided at the other end having a smaller diameter. In addition to protecting and shielding the motor, the flow straightening cover 14 also serves to guide the airflow, regulating the airflow during operation of the high-speed electric air duster, reducing ventilation resistance, and suppressing operating noise.

[0028] In the rotating high-speed electric air duster with side air intake of this invention, the main unit 1 and the battery unit 2 are arranged in a straight line when the second inclined surface 11 and the first inclined surface 9 are perfectly aligned (see Figure 7). When the motor is operated, outside air flows in from the side air intake port 4 into the intake cover 7 and the main unit frame 5, and the airflow passes through the rectifier cover 14 before being guided to the exhaust cover 6 and discharged from the exhaust cover 6. This allows for air blowing work to be performed on objects that require air blowing.

[0029] In situations where it is difficult to reach certain areas with the main unit 1 and battery unit 2 in a straight configuration, such as corners, it becomes necessary to rotate the main unit 1 and battery unit 2 by a predetermined angle. In this case, the button knob 23 is operated to slide the button slider 24 axially, disengaging the two pillars from the two shaft holes. Then, when either the main unit 1 or the battery unit 2 is rotated, the rotation shaft 10 rotates within the rotation shaft hole 13, causing the main unit 1 and battery unit 2 to rotate relative to each other and forming a predetermined angle between them (see Figure 8). This enables effective air blowing even in situations where it was previously difficult.

[0030] In a preferred embodiment, a cylindrical guide cover 16 is provided at the other end of the intake cover 7, and the guide cover 16 covers the motor 3 inside the main engine frame 5, with both ends being open. This allows the airflow to pass through the guide cover 16, which regulates the airflow entering from the side intake port 4 and guides the airflow smoothly. This solves the problem of wind noise caused by high-speed airflow and significantly reduces the operating noise of the high-speed electric air duster.

[0031] In another preferred embodiment, a wire groove 17 is installed between the outer wall of the guide cover 16 and the inner wall of the main unit frame 5, and some of the external wires of the motor 3 are housed in the wire groove 17. This prevents the wires from being exposed, thus preventing exposed wires from causing friction with the high-speed airflow, obstructing the airflow, or generating noise. Housedting the wires in the wire groove 17 also contributes to reducing the operating noise of the high-speed electric air duster.

[0032] By combining and applying the above-mentioned noise reduction measures, the operating noise of high-speed electric air dusters can be significantly reduced, improving the consumer experience.

[0033] In a preferred embodiment, a conductive plug 18 is provided at one end of the battery unit 2, allowing for conductive connection to other electrical products via this plug 18 even after the battery unit 2 has been removed. This expands the range of applications for the battery.

[0034] In another preferred embodiment, a locking claw 19 is provided at one end of the battery unit 2, and a locking groove 20 is provided in the connecting frame 8. By fitting the locking claw 19 into the locking groove 20, the connecting frame 8 and the battery unit 2 can be attached and detached easily and reliably.

[0035] In yet another preferred embodiment, the other end of the battery unit 2 is provided with a plurality of anti-tipping legs 21, two of which have mounting openings 22. When the high-speed electric air duster is not in use, these anti-tipping legs 21 prevent the device from rolling off the floor. In addition, a safety strap can be attached to the two mounting openings 22, allowing the user to hold the device by hand and increasing convenience.

[0036] The provisions described herein are merely embodiments of the present invention and do not limit the scope of the patent. Any modifications to equivalent structures or processes using the provisions of this specification, or any applications directly or indirectly to other related technical fields, shall all be similarly included within the scope of the patent protection of this invention.
