[0050] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0051] like Figure 1-7As shown, the multifunctional cleaning device includes a cleaning head 8; and also includes: a backpack 1, two shoulder straps 101 are provided on the back of the backpack 1; a ducted fan 2 is provided in the backpack 1, and the air outlet of the ducted fan 2 is connected to a hose 6; a humidifier 3, the humidifier 3 is installed on the air inlet of the ducted fan 2; a telescopic air outlet pipe 7, one end of the telescopic air outlet pipe 7 is fixedly connected to one end of the hose 6, and the other end of the telescopic air outlet pipe 7 is plugged into the cleaning head 8, and a self-locking mechanism 9 for locking the cleaning head 8 is installed on the end of the telescopic air outlet pipe 7 away from the hose 6; the self-locking mechanism 9 has a movable locking block 902 that is plugged into the cleaning head 8, and one end of the locking block 902 is located outside the telescopic air outlet pipe 7.

[0052] like Figure 2 As shown, the air inlet and air outlet of the ducted fan 2 are respectively arranged outside the two sides of the backpack 1, and the air inlet of the ducted fan 2 is installed with a filter 201.

[0053] The filter 201 is used to filter out dust and foreign matter to prevent them from entering the ducted fan 2 .

[0054] like Figure 1-2 As shown, it also includes a power supply 4 and a controller 5, and the power supply 4 and the controller 5 are both arranged on the top surface of the casing of the ducted fan 2.

[0055] The power source 4 is preferably a rechargeable lithium battery. The power source 4 supplies power to the ducted fan 2 and the humidifier 3, and the controller 5 provides control.

[0056] This device has multiple functions and is retractable and portable.

[0057] When performing cleaning operations, the staff carries the backpack 1 on their back using the shoulder straps 101. After carrying the backpack 1, the backpack 1 is placed in front of the chest and abdomen. The staff holds the telescopic air outlet duct 7 with their hands and stretches the telescopic air outlet duct 7 to adjust the length of the telescopic air outlet duct 7 according to the height of the facility. The ducted fan 2 is then started to generate airflow. The airflow passes through the hose 6 and the telescopic air outlet duct 7 and enters the curved pipe 801 of the cleaning head 8. The airflow is then ejected through the air outlet head 802, brushed by the bristles 803 on the cleaning head 8, and the ejected airflow is used to blow away dust and dirt.

[0058] The hose 6 is a plastic corrugated tube.

[0059] like Figure 4-6 As shown, the telescopic air outlet pipe 7 is formed by a plurality of tube bodies 701 being sleeved together, and the diameters of the plurality of tube bodies 701 gradually increase from the inside to the outside.

[0060] A retaining ring 702 is fixedly installed on the inner wall of the outermost tube body 701, and the bottom ends of the other tube bodies 701 are all provided with bottom edges 703; a sealing ring 704 is provided on the outer peripheral surface of the bottom edge 703; the top ends of several tube bodies 701 extend inward to form top edges 705.

[0061] Telescopic movement is achieved by sliding between the tube bodies 701 and adjusting the extension amount, wherein the sealing ring 704 is used to seal between two adjacent tube bodies 701. At the same time, the sealing ring 704 is in close contact with the wall of the tube body 701 and has a large friction force, which is used to limit the position after telescopic adjustment.

[0062] like Figure 5 As shown, the retaining ring 702 and the bottom edge 703 are used to allow the retractable air outlet pipe 7 to be in the retracted state, and the pipe bodies 701 are stacked on each other to maintain the retracted state.

[0063] like Figure 6 As shown, the top edge 705 of a single tube body 701 is in close contact with the outer wall of the adjacent tube body 701 on its inner side, and has a large friction force. This friction force cooperates with the friction force of the sealing ring 704 to provide a limit after extension and retraction.

[0064] like Figure 3 As shown, the cleaning head 8 includes a curved tube 801, an air outlet head 802 and bristles 803; one end of the curved tube 801 is plugged into the top end of the innermost tube body 701 of the telescopic air outlet pipe 7, and the other end of the curved tube 801 is fixedly connected to the air outlet head 802, and the air outlet head 802 is provided with bristles 803.

[0065] like Figure 7 As shown, the self-locking mechanism 9 includes a grip block 901, a first spring 903 and a guide hole 904; the guide hole 904 is provided on the innermost tube body 701 of the telescopic air outlet duct 7, the locking block 902 is cooperated with the guide hole 904, one end of the locking block 902 is fixedly connected to the grip block 901, the grip block 901 is elastically connected to the outer wall of the tube body 701 through the first spring 903, the first spring 903 is sleeved on the locking block 902, a locking hole 8013 is provided on the outer wall of the bent pipe 801, and one end of the locking block 902 is plugged into the locking hole 8013.

[0066] A chamfered surface 8011 is provided on the outer edge of the bottom end of the curved pipe 801 , and an inclined surface 9021 adapted to the chamfered surface 8011 is provided on the top of one end of the locking block 902 .

[0067] A convex ring 11 is fixedly mounted on the inner wall of the innermost tube body 701 of the telescopic air outlet duct 7 , and a sealing gasket 10 is provided on the top surface of the convex ring 11 . The sealing gasket 10 is fitted with the bottom end surface of the curved tube 801 .

[0068] A fixing block 13 is fixedly installed on the inner wall of the tube body 701, and the fixing block 13 is fixedly connected to the second spring 12. The second spring 12 passes through the convex ring 11. A retaining ring 8012 is fixedly installed inside the bottom end of the bent tube 801, and the bottom surface of the retaining ring 8012 abuts against the top of the second spring 12.

[0069] like Figure 7 As shown, the cleaning head 8 is in an installed state, wherein the second spring 12 is in a compressed state. When disassembling the cleaning head 8, by holding the grip block 901 and pulling the locking block 902, the locking block 902 slides in the guide hole 904, and the locking block 902 is pulled out of the locking hole 8013. At the same time, the first spring 903 is stretched, and the bent pipe 801 loses the limit of the locking block 902. The compressed elastic force of the second spring 12 pushes the cleaning head 8 to move, so that the locking hole 8013 and the locking block 902 are in an unaligned state. The grip block 901 is released, and the bent pipe 801 is pulled out to complete the disassembly, and the locking block 902 is reset by the elastic force of the first spring 903.

[0070] During installation, the elbow 801 is inserted into the innermost tube body 701 of the telescopic air outlet duct 7, and the chamfered surface 8011 is used to squeeze the inclined surface 9021 of the locking block 902 so that the end of the locking block 902 with the inclined surface 9021 is squeezed into the guide hole 904. At the same time, the first spring 903 is stretched, and the elbow 801 continues to move into the tube body 701. The second spring 12 is compressed by the retaining ring 8012 until the sealing gasket 10 fits with the bottom end surface of the elbow 801. At this time, the locking block 902 is at the same height as the locking hole 8013. The elbow 801 is rotated to align the locking hole 8013 with the locking block 902. The elastic force of the first spring 903 is used to insert the locking block 902 into the locking hole 8013 for positioning and completion of installation.

The scope of protection of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention. Such changes and modifications shall fall within the scope of protection of the present invention.
