DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] To make the technical means, creative features, achieved objectives and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] As Figures 1 - 4 shown, a fallen leaf blowing machine with adjustable cleaning range includes a main machine box 1, a driving motor 3 and an operating handle 4. The driving motor 3 is fixedly installed at the rear end of the main machine box 1, the operating handle 4 is fixedly installed outside the driving motor 3, a rotating pipe 5 is fixedly installed on one side of the main machine box 1, a connecting rotating shaft 6 is fixedly installed on the outside of the rotating pipe 5, a rotating mounting plate 7 is movably installed at the upper end of the connecting rotating shaft 6, an adjusting handle 8 is welded at the upper end of the rotating mounting plate 7, an adjusting connecting rod 9 movably penetrates through the rotating mounting plate 7, one end of the rotating pipe 5 is fixedly installed with a first bent pipe 10, one end of the first bent pipe 10 is fixedly installed with a first adjusting ring 11, a first docking block 12 is integrally formed on the outside of the first adjusting ring 11, one end of the first adjusting ring 11 is fixedly installed with a wind guiding pipe 13, one end of the wind guiding pipe 13 is fixedly installed with a second bent pipe 14, one end of the second bent pipe 14 is fixedly installed with a second adjusting ring 15, a second docking block 16 is integrally formed on the outside of the second adjusting ring 15, and an air outlet 17 is fixedly installed at one end of the second adjusting ring 15.

[0020] In this embodiment, an air inlet 2 is fixedly installed at the front end of the main machine box 1. The air inlet 2 communicates with the inside of the main machine box 1 and serves to introduce air.

[0021] In this embodiment, the rotating pipe 5 communicates with the inside of the main machine box 1, and the interiors of the rotating pipe 5, the first bent pipe 10, the first adjusting ring 11, the wind guiding pipe 13, the second bent pipe 14, the second adjusting ring 15 and the air outlet 17 are all communicated. Air sequentially passes through the rotating pipe 5, the first bent pipe 10, the first adjusting ring 11, the wind guiding pipe 13, the second bent pipe 14 and the second adjusting ring 15, and finally is discharged from the air outlet 17.

[0022] In this embodiment, the rotating mounting plate 7 rotates around the connecting rotating shaft 6, and the adjusting connecting rod 9 expands and contracts around the inside of the rotating mounting plate 7. The connecting rotating shaft 6 serves to movably install the rotating mounting plate 7.

[0023] In this embodiment, the front end of the adjusting connecting rod 9 is inserted into the first docking block 12 for mating connection. The second docking block 16 is located in front of the adjusting connecting rod 9. When the rotating mounting plate 7 rotates, the first docking block 12 is rotated through the adjusting connecting rod 9.

[0024] In this embodiment, the middle part of the rotating pipe 5 is provided with a rotating structure. The connecting rotating shaft 6 rotates through the rotating pipe 5, and the rotating pipe 5 changes the installation position of the connecting rotating shaft 6 through the rotation of the middle part.

[0025] It should be noted that the present utility model is a leaf blowing machine with adjustable cleaning range. When in use, the blowing machine is grasped by using the operating handle 4. The operation of the driving motor 3 drives the fan blades in the main machine box 1 to rotate, so that the main machine box 1 sucks air from the air inlet 2 and conveys the air under high pressure through the rotating pipe 5. The air is discharged from the air outlet 17 through the rotating pipe 5, the first bent pipe 10, the first adjusting ring 11, the air guiding pipe 13, the second bent pipe 14 and the second adjusting ring 15, thereby using the blown air to carry out the leaf blowing operation;

[0026] When it is necessary to adjust the air discharge angle of the air outlet 17, grasp the adjusting handle 8 and rotate it, so that the rotating mounting plate 7 rotates around the connecting rotating shaft 6, and at the same time drives the adjusting connecting rod 9 to rotate. Then the adjusting connecting rod 9 drives the first adjusting ring 11 to rotate through the first docking block 12, so that the first adjusting ring 11 pulls the first bent pipe 10 to bend in parallel, so as to change the parallel angle of the air outlet 17 and carry out leaf blowing in different angle ranges;

[0027] When it is necessary to adjust the up and down angle of the air outlet 17, move the adjusting connecting rod 9 to one side to disconnect the connection with the first docking block 12. The rotation of the rotating pipe 5 makes the connecting rotating shaft 6 and the rotating mounting plate 7 rotate by 45°. Then extend the adjusting connecting rod 9 and insert it into the second docking block 16. Therefore, when the adjusting handle 8 and the rotating mounting plate 7 are rotated again, the adjusting connecting rod 9 drives the second adjusting ring 15 to rotate through the second docking block 16, so that the second adjusting ring 15 pulls the second bent pipe 14 to bend up and down, so as to change the up and down angle of the air outlet 17 and carry out leaf blowing at different up and down positions.

[0028] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
