[0031] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0032] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figure 1-4 As shown, a vacuum cleaner duct structure includes a first tube body 1, a main unit connector 2, a second tube body 3, an accessory connector 4, a first connector 5, a second connector 6, a telescopic hose 7, and an anti-rotation component. The main unit connector 2 is fixedly connected to the end of the first tube body; the accessory connector 4 is fixedly connected to the end of the second tube body; the first connector 5 is fixed to the end of the first tube body; the second connector 6 is rotatably connected to the first connector via a hinge 10 and is fixed to the second tube body; the telescopic hose 7 is a corrugated pipe, with one end fixed to the first connector and the other end fixed to the second connector; the anti-rotation component restricts the rotation between the first connector and the second connector. When cleaning low spaces, rotating the first connector causes the first tube body to rotate, forming a bent tube body, allowing the second tube body and the accessories connected to its accessory connector to be inserted into the low space for easy cleaning. When cleaning normal spaces, the first tube body can be rotated to a position where the axes of the first tube body and the second tube body coincide, forming a straight tube body. The anti-rotation component then restricts the rotation of the first connector, allowing for cleaning of normal spaces.

[0034] Specifically, the anti-rotation assembly includes a control plate 81, a latch 82, and an elastic element 83. The control plate 81 is rotatably connected to the first connector. The control plate has protrusions on both sides, and the first connector has a round hole 51 for the protrusions to be inserted and rotated. The latch 82 is fixed to the end of the control plate, and the second connector has a slot 61 for the latch to be engaged. The elastic element 83 is a metal spring, one end of which is fixed to the bottom surface of the control plate, and the other end is fixed to the first connector. When it is necessary to restrict the rotation of the first connector, the latch can be pressed into the slot, and the first connector will not be able to rotate. When it is necessary to rotate the first connector, one end of the control plate is pressed, and the control plate is rotated, thereby turning the latch out of the slot, and thus releasing the rotation restriction. The elastic element 83 is provided to prevent the latch from automatically dislodging from the slot.

[0035] In other embodiments, a groove 811 is provided on the top surface of the control plate 81 to increase the friction at the pressing point, making it easier to unlock the control plate by pressing. Pressing the groove 811 on the top surface of the control plate 81 releases the latch 82, and the first tube 1 and the second tube 3 are rotated by the hinge to form a bent tube, so that the second tube and the accessories connected to its accessory joint can be inserted into the low space, making cleaning very convenient. When cleaning the normal space, the first tube can be rotated to a position where the axes of the first tube and the second tube coincide, and the first tube and the second tube will form a straight tube. The latch will automatically engage in the slot for locking, and the rotation of the first joint is restricted by the anti-rotation component, so that the normal space can be cleaned.

[0036] In other embodiments, a fixing frame 62 is integrally formed on the second connector 6, a rotating shaft 63 is rotatably connected to the fixing frame, and a roller 64 is fixed on the rotating shaft. The roller can prevent the second pipe from directly contacting the ground during use.

[0037] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
