[0026] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application.

[0027] The following is in conjunction with the appendix Figure 1-6 The embodiments of this application will be described in further detail.

[0028] This application discloses a leaf blower with reversible wind direction. (Refer to...) Figures 1-4 A leaf blower with reversible airflow direction includes a leaf blower assembly and an airflow control mechanism. The leaf blower assembly includes a frame 5 and a fan cover 1 mounted on the frame 5. The bottom of the fan cover 1 has a horizontal air outlet channel 11. In this embodiment, the forward or backward movement of the leaf blower is the direction of travel of the leaf blower, and the horizontal direction is perpendicular to the direction of travel. In this embodiment, the air outlet channel 11 is located on the left side of the fan cover 1. An air guide assembly 2 is installed inside the air outlet channel 11 in the fan cover 1. The air guide assembly 2 includes a horizontal air guide 21 and a vertical air guide 22. In this embodiment, the upper and lower ends of the horizontal air guide 21 are both identical circular plates. The two circular plates are connected together by vertical plates, so that the space between the two circular plates forms an air outlet that communicates with the air outlet channel 11. The horizontal air guide 21 is a single plate, forming an air guide plate. On both sides of the air outlet, the horizontal air guide 21 has flared plates 25 that are inclined to both sides, making the air outlet funnel-shaped.

[0029] A circular groove 12 is provided on the bottom side of the fan cover 1 located in the air outlet channel 11. The bottom end of the horizontal air guide 21 is rotatably disposed in the groove 12, allowing the horizontal air guide 21 to rotate horizontally on the air outlet channel 11. The vertical air guide 22 is oscillatingly disposed between two flared plates 25. In this embodiment, there are two vertical air guides 22, arranged one above the other. The two ends of the two vertical air guides 22 on the side closer to the air outlet channel 11 are rotatably disposed on the two flared plates 25, while the side of the two vertical air guides 22 away from the air outlet channel 11 is movable, allowing the two vertical air guides 22 to oscillate up and down within the horizontal air guide 21, adjusting the vertical air outlet direction of the horizontal air guide 21.

[0030] Reference Figures 3-6 The wind direction control mechanism includes a horizontal wind direction control component 3 and a vertical wind direction control component 4 for controlling the airflow direction. The horizontal wind direction control component 3 includes an operating lever 31 and adjusting ropes 32. The operating lever 31 is set on one of the handrails of the frame 5. There are two adjusting ropes 32, one end of which is connected to the operating lever 31. Two cable lugs 28 are fixed at the top of the horizontal air guide 21 near the edges on both sides. The two adjusting ropes 32 are respectively connected to the two cable lugs 28. By operating the operating lever 31, the two adjusting ropes 32 can pull the horizontal air guide 21, so that the horizontal air guide 21 can rotate 180 degrees in the horizontal direction, thereby adjusting the horizontal airflow of the horizontal air guide 21. The vertical wind direction control component 4 includes an operating handle 41 and a pull rope 42. The operating handle 41 is set on another handrail of the frame 5. One end of the pull rope 42 is connected to the operating handle 41, and the other end of the pull rope 42 is connected to two vertical air guides 22. By operating the operating handle 41, the pull rope 42 is controlled to pull the two vertical air guides 22 to swing.

[0031] Reference Figure 3 and Figure 4 A cover plate 24 is fixedly installed on the top of the horizontal air guide 21. The cover plate 24 has a round hole for installing the horizontal air guide 21. The top of the horizontal air guide 21 can just pass through the round hole and can rotate. The cover plate 24 is fixed to the top of the air outlet channel by bolts. The cover plate 24 can seal the space between the top wall of the air outlet channel 11 and the top of the horizontal air guide 21. At the same time, in order to better seal the cover plate 24 and the horizontal air guide 21, an annular groove is provided on the periphery of the end of the horizontal air guide 21 that passes through the cover plate 24. An annular elastic retaining ring 27 is inserted in the groove. In this embodiment, the elastic retaining ring 27 is a rubber ring. The bottom side of the elastic retaining ring 27 abuts against the cover plate 24 and can seal the gap between the cover plate 24 and the horizontal air guide 21.

[0032] Reference Figure 2 , Figure 3 and Figure 4The air outlet duct 11 is equipped with baffles 23 on both sides to seal the space between the side walls of the air outlet duct 11 and the horizontal air guide 21. The fan cover 1 has grooves 13 on both sides at the bottom of the air outlet duct 11. The bottom of the baffles 23 is slidably disposed in the grooves 13. In this embodiment, the baffles 23 are roller shutters. Bosses 211 are provided on the side walls of the horizontal air guide 21. Long strip-shaped limiting holes 231 are opened on both baffles 23 in the horizontal direction. The bosses 211 on the two side walls of the horizontal air guide 21 are inserted into the limiting holes 231. When the horizontal air guide 21 rotates, the bosses 211 can drive the baffles 23 to stretch and roll up, sealing the space between the horizontal air guide 21 and the side walls of the air outlet duct 11, and preventing air leakage between the horizontal air guide 21 and the side walls of the air outlet duct 11.

[0033] Reference Figure 3 and Figure 4 Each of the two flared plates 25 has two arc-shaped guide grooves 251, with one guide groove on each side positioned vertically. Each of the two vertical air guides 22 has a guide rod 221 on its swinging side, with both ends of the guide rod 221 passing through the guide groove 251. When the vertical air guide 22 swings up and down, the ends of the guide rod 221 can slide within the guide groove 251. In this embodiment, the swing angle of the two vertical air guides 22 is 30°, allowing the vertical airflow direction of the blower to be adjusted up and down by 30°. Simultaneously, the guide groove 251 also limits the swing of the two vertical air guides 22, preventing excessive swing angles that could lead to wasted power in the blower. In other embodiments, the length of the guide groove 251 can be designed to limit the swing angle of the vertical air guide 22 according to actual conditions.

[0034] Reference Figure 3 and Figure 4 In order to enable the two vertical air guides 22 to swing up and down simultaneously, a pull rod 26 is connected between the same end of the two guide rods 221. The pull rod 26 is located on the opposite side of the two flared plates 25. A cable lug 28, the same as described above, is fixedly installed on one of the pull rods 26. The pull rope 42 is connected to the cable lug 28. When adjusting the vertical air outlet direction, the pull rod 26 is pulled by the pull rope 42. The pull rod 26 drives the two guide rods 221 to slide in the guide groove 251, so that the two vertical air guides 22 swing in the same direction, thereby adjusting the vertical air outlet direction.

[0035] Reference Figure 3 and Figure 4To prevent the adjusting rope 32 and the pull rope 42 from getting tangled on the leaf blower, a rubber tube is fixed on the leaf blower. Pull rope lugs 28 are installed on both sides of the top of the cover plate 24 and on the flared plate 25 where the pull rope lugs 28 are provided. The rubber tube is fixed on these three pull rope lugs 28. The adjusting rope 32 passes through the rubber tube and is fixed on the pull rope lug 28 at the top of the horizontal air guide 21. The pull rope 42 passes through the rubber tube and is fixed on the pull rope lug 28 on the pull rod 26. This can prevent the adjusting rope 32 and the pull rope 42 from getting tangled on various parts of the leaf blower when moving.

[0036] The operating principle of the air outlet direction control device for this type of leaf blower is as follows: When the leaf blower is turned on, the operating lever 31 moves the two adjusting ropes 32 in opposite directions. During this movement, the two adjusting ropes 32 pull the horizontal air guide 21 to rotate, allowing it to rotate 180° horizontally, thus adjusting the horizontal air outlet direction of the leaf blower. The operating handle 41 then moves the pull rope 42. During this movement, the pull rope 42 pulls the pull rod 26, which in turn moves the two guide rods 221 within the guide groove 251, causing the two vertical air guides 22 to swing simultaneously in the same direction, thus adjusting the vertical air outlet direction of the leaf blower.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application, and all such modifications or substitutions should be covered within the scope of the claims of this application.
