Referring to
In the embodiment, the air supply device 2 also includes a motor 23, and the motor 23 is provided with a driving rotating shaft 231. The air supply device 2 also includes a support 24. The motor 23 is arranged inside the support 24. The support 24 is provided with a first connecting part 241. The support 24 is connected with the shell 1 through the first connecting part 241. The driving rotating shaft 231 goes through the support 24 and is connected with the fan blade 21. The motor 23 is used for driving the fan blade 21 to rotate so as to produce high-speed airflow. The motor 23 is fixed in the shell 1 through the support 24.
In the embodiment, the air supply device 2 also includes a gasket 25. The gasket 25 is arranged between the motor 23 and the fan blade 21. A connecting hole 213 is also formed in the fan blade 21. The connecting hole 213 sleeves the rotating shaft 231. The gasket 25 is arranged between the motor 23 and the fan blade 21. The motor 23 is avoided from being in direct contact with the fan blade 21 to play a role of shock absorption.
In the embodiment, the fan blade 21 is also provided with a partition plate 26. The partition plate 26 is located between the first wind wheel 211 and the second wind wheel 212 and used for partitioning the first wind wheel 211 and the second wind wheel 212. The first wind wheel 211 is provided with a plurality of first wind blades 2111. The second wind wheel 212 is provided with a plurality of second wind blades 2121. The first wind blades 2111 and the second wind blades 2121 are mutually staggered. The partition plate 26 is arranged between the first wind wheel 211 and the second wind wheel 212. The airflow passing through the first wind wheel 211 and the airflow passing through the second wind wheel 212 do not interfere with each other through the partition plate 26.
In the embodiment, the air inlet 11 includes a first air inlet unit 111 and a second air inlet unit 112. A first air flue 1112 is formed between the first air inlet unit 111 and the first wind wheel 112. A second air flue 2112 is formed between the second air inlet unit 112 and the second wind wheel 212. The first wind wheel 211 drives airflow to pass through the first air inlet unit 111, the first air flue 1112, the first wind wheel 211 and the air outlet 12 in sequence to form high-speed airflow. The second wind wheel 212 drives airflow to pass through the second air inlet unit 112, the second air flue 2112, the second wind wheel 212 and the air outlet 12 in sequence to form high-speed airflow. The theoretical air volume of the air blower when in use is increased through the design of double-sided air inlet.
In the embodiment, the air blower also includes a handle 3. The handle 3 is connected with the shell 1. The product can be used more conveniently by the user through the design of the handle 3.
In the embodiment, the air blower also includes an extension device 4. The extension device 4 is detachably arranged at the air outlet 12. The extension device 4 includes an air outlet extension tube 41 and an air outlet nozzle 42. One end of the air outlet extension tube 41 is detachably connected with the air outlet 12, and the other end of the air outlet extension tube 41 is detachably connected with the air outlet nozzle 42. Through the above-mentioned structure, the effect of prolonging the air flue is achieved by using the air outlet extension tube 41 and the air outlet nozzle 42 under the condition that the air outlet 12 is short in specific usage scenarios.
In the embodiment, the partition plate is provided with an upper surface and a lower surface, the first wind blades are connected to the upper surface of the partition plate, and the second wind blades are connected to the lower surface of the partition plate.

Still further, the partition plate is a flat partition plate, the upper surface of the partition plate is a flat upper surface, and the lower surface of the partition plate is a flat lower surface. Still further, the partition plate is a circular partition plate. Still further, the wind wheels are located between the first air inlet unit 111 and the second air inlet unit 112. Still further, the first air inlet unit 111 is arranged on a left side wall 10111 of the shell, and the second air inlet unit 112 is arranged on a right side wall 10112 of the shell. Still further, the first air inlet unit 111 is arranged facing towards the second air inlet unit 112. Still further, the first air inlet unit 111 and/or the second air inlet unit 112 at least include/includes first air inlet holes 10113 and second air inlet holes 10114, and the sizes of the first air inlet holes 10113 and the second air inlet holes 10114 are different. Still further, the second air inlet unit 112 at least includes first air inlet holes 10113 and second air inlet holes 10114, the first air inlet holes 10113 are smaller than the second air inlet holes 10114, and the first air inlet holes 10113 and the second air inlet holes 10114 are arranged in sequence from the center of the right side wall 10112 to the edge of the right side wall 10112. Still further, the first air inlet holes 10113 and the second air inlet holes 10114 are all fan-shaped first air inlet holes 10113.
