[0040] Example

[0041] To address the issue that existing vacuum cleaners require complex operations using hoses to achieve their blowing function, refer to... Figures 1-9 As shown, in some embodiments, the handheld vacuum cleaner with blower and suction integrated according to this application includes a motor unit 10, a rotating cover plate 20, a fixed cover plate 30 and a dust cup 40.

[0042] The rotating cover 20 is rotatably mounted on the bottom of the motor unit 10, and the fixed cover 30 is mounted on the bottom of the rotating cover 20 and fixed to the motor unit 10. The rotating cover 20 can be adjusted to form an air blowing channel and an air suction channel. The dust cup 40 is fixedly mounted on the bottom of the fixed cover 30 for blowing and suction.

[0043] In addition, it also includes a battery pack 50, which consists of a handle 51, a battery assembly 52, and a control assembly 53. The handle 51 is located above the motor rear cover 13, and the battery assembly 52 and the control assembly 53 are both located inside the handle 51. In actual use, the operator can hold the handle 51 to move the handheld vacuum cleaner, and the control assembly 53 can control the battery assembly 52 to supply power to the motor body 12.

[0044] When the rotating cover plate 20 and the fixed cover plate 30 form an air blowing channel, the motor unit 10 will blow out gas through the air blowing channel to the dust cup 40 when it is powered on. At this time, the blown gas will blow away dust or other debris in the external environment.

[0045] When the rotating cover plate 20 and the fixed cover plate 30 form an air intake channel, the motor unit 10 will be powered on and will draw air through the air intake channel. At this time, dust or other debris in the external environment will enter the dust cup 40.

[0046] With the above structural design, the operator can change the air intake and exhaust direction by simply operating the rotating cover 20 to achieve blowing or suction, which reduces the difficulty of operation.

[0047] In one specific embodiment, the motor part 10 of this application includes a motor housing 11, a motor body 12, and a motor rear cover 13. The motor body 12 is disposed inside the motor housing 11, and the motor rear cover 13 is disposed on the top of the motor housing 11. During specific operation, the motor body 12, as a power component, generates negative pressure to allow external gas to enter the motor housing 11. In a preferred embodiment, this application has an integrally provided positioning ring 115 on the inner bottom surface of the motor housing 11, and a motor sealing ring 14 is provided at the bottom of the motor body 12 and assembled in the positioning groove. This method achieves sealed installation of the motor body 12 and improves the quality of air intake and blowing.

[0048] In order to enable the rotating cover 20 to form an air blowing channel and an air suction channel with the fixed cover 30 by switching the angle, this application discloses the following structure of motor housing 11, rotating cover 20 and fixed cover 30.

[0049] <Motor housing 11>, the bottom center of the motor housing 11 is integrally provided with a wind chamber 111 connected thereto, the side wall of the wind chamber 111 is provided with a first air vent 1111, and the bottom edge of the motor housing 11 is also provided with a second air vent 112.

[0050] <Rotating cover plate 20>, the rotating cover plate 20 is a hollow structure, and an annular groove 21 is integrally formed on the upper edge of the rotating cover plate 20. A third air vent 22 is opened at the bottom of the annular groove 21. A blocking part 23 communicating with the hollow structure is provided in the annular groove 21 away from the third air vent 22. Air ducts 24 communicating with the blocking part 23 and close to but not communicating with the third air vent 22 are respectively opened on both sides of the rotating cover plate 20. In order to prevent the air ducts 24 on the periphery of the rotating cover plate 20 from flowing with the third air vent 22, this application provides a number of partitions 25 inside the annular groove 21.

[0051] <Fixed cover plate 30>, a fourth air vent 31 is provided on one side of the fixed cover plate 30; a fifth air vent 32 is provided along the edge of the fixed cover plate 30;

[0052] When the rotating cover plate 20 rotates and the blocking part 23 blocks the fourth air outlet 31, the third air outlet 22 and the fifth air outlet 32 ​​form an air blowing channel; when the rotating cover plate 20 rotates and the blocking part 23 blocks the fifth air outlet 32, the fourth air outlet 31 and the hollow structure form an air intake channel.

[0053] Based on the above structure, during the suction process: the operator first twists the rotating cover plate 20 to block the fifth air outlet 32 ​​with the blocking part 23. When the motor body 12 is powered on, the external gas is drawn from the dust cup 40 and passes through the fourth air outlet 31 of the fixed cover plate 30, the hollow structure of the rotating cover plate 20, the first air outlet 1111 of the air chamber 111 to the motor housing 11. Then it is discharged from the second air outlet 112 of the motor housing 11 to the air groove 24 of the rotating cover plate 20, which is not connected to the third air outlet 22. At this time, external dust or other debris is drawn into the dust cup 40 for collection.

[0054] During the blowing process: The operator first twists the rotating cover plate 20 to block the fourth air outlet 31 with the blocking part 23. When the motor body 12 is powered on, the gas is drawn from the air groove 24 connected to the blocking part 23 into the hollow structure of the rotating cover plate 20, and then through the first air outlet 1111 of the air chamber 111 to the motor housing 11. Finally, the gas coming out of the motor housing 11 passes through the second air outlet 112 of the motor housing 11, the third air outlet 22 of the rotating cover plate 20, and the fifth air outlet 32 ​​of the fixed cover plate 30 to the dust cup 40 and is blown out. At this time, dust or other debris in the external environment will be blown away.

[0055] In one specific embodiment, the present application has an integrally formed suction head 41 at the bottom of the dust cup 40, and an integrally formed blowing head 42 extending into the dust cup 40 on the side; when the rotating cover plate 20 and the fixed cover plate 30 form a suction channel, external air will enter the dust cup 40 from the suction head 41.

[0056] When the rotating cover plate 20 and the fixed cover plate 30 form an air blowing channel, the blown gas will be blown out from the blower head 42; Reference Figure 9 As shown, the suction head 41 of this application has a round hole with a large inner diameter, which allows it to draw in more air. The blower head 42 has a flat hole with a small inner diameter, which allows the blown gas to have a greater force to blow away dust that cannot be drawn in from the external environment.
