[0002] In the prior art, the air regulating bend of a vacuum cleaner is usually equipped with an air regulating device to adjust the air volume. Most existing air regulating devices are push-button type structures, such as the air regulating bend of the CN103211556B vacuum cleaner, which includes an air outlet and an air regulating device connected to the air outlet. The air regulating device includes a push button and a latching component connected to the push button. The latching component is slidably latched to the air outlet. The latching component has latching portions on both sides, which latch to the side of the air outlet. A support portion is provided on the side of the air outlet, and the push button is supported on the support portion. The support portion is a groove, and the side of the push button is located in the groove. The push button and the latching component are connected by a snap-fit ​​or screw connection. While the vacuum cleaner's adjustable bend with the above-mentioned structure has the advantages of good stability and reliable installation, the air adjustment device is directly fastened to the air outlet by a snap-fit ​​component. Then, the push button connected by screws or snap-fit ​​components moves within the air outlet to adjust the air volume. This makes the disassembly and assembly of the air adjustment device and the bend relatively troublesome, and there is room for improvement. Utility Model Content
