[0002] When sanitation workers handle fallen leaves, they usually use a portable leaf blowing machine. The existing portable leaf blowing machine includes a main body, a blowing tube and a suction tube connected to the main body. When in use, hold the main body, use the blowing tube to blow the scattered fallen leaves together, and then the suction tube sucks the gathered fallen leaves into the main body for crushing and storing in a hanging bag. Finally, the crushed fallen leaves collected and stored in the hanging bag for many times are processed.

[0055] See Figures 1 to 7 , this embodiment provides a portable leaf blower, which includes a main body 10, a first blowing tube 20, a first connecting member 21, a second blowing tube 22 and a connecting tube 23.

[0056] The main body 10 adopts the prior art. An inhalation tube is also connected to the main body 10. Air can be conveyed from the main body 10 to the blowing tube, and the main body 10 can inhale air from the inhalation tube.

[0057] The end of the first blowing tube 20 is in communication with the main body 10. The first connecting member 21 is rotatably connected to the end of the first blowing tube 20 away from the main body 10. The second blowing tube 22 is connected to the end of the first connecting member 21 away from the first blowing tube 20. The connecting tube 23 is bendable, and the two ends of the connecting tube 23 are respectively connected to the first blowing tube 20 and the second blowing tube 22. A roller 24 is rotatably provided at the end of the second blowing tube 22 away from the first blowing tube 20. The first blowing tube 20 and the second blowing tube 22 can remain relatively stationary.

[0058] In this embodiment, the sanitation worker holds the main body 10, and the roller 24 at the lower end of the second blower 22 is placed on the ground. The sanitation worker then pushes the main body 10 to blow the fallen leaves on the ground. At this time, the second blower 22 is in an inclined state. When the fallen leaves gather into a pile, the second blower 22 is adjusted so that the second blower 22 rotates around the first blower 20 by a certain angle and then the relative static state between the two is maintained. At this time, the second blower 22 can be in a horizontal state, and the blown air can blow horizontally towards the upper layer of the fallen leaf pile, thus more efficiently blowing the fallen leaf pile. In addition, the sanitation worker does not need to greatly adjust the height of the main body 10 at one end of the main body 10, which is relatively labor-saving.

[0059] In one embodiment, the connecting pipe 23 is a corrugated pipe.

[0060] In one embodiment, the portable fallen leaf blowing machine further includes a first sprocket 30, a second sprocket 31, a chain 32, and a driving mechanism 40.

[0061] The first sprocket 30 is rotatably arranged on the outer wall of the end of the first blower 20 away from the main body 10 and is fixedly connected to the end of the first connecting member 21. The second sprocket 31 is rotatably arranged on the outer wall of the end of the first blower 20 close to the main body 10. The chain 32 is wound around the first sprocket 30 and the second sprocket 31 and meshes with the first sprocket 30 and the second sprocket 31 respectively. The driving mechanism 40 can drive the chain 32 to move, and the driving mechanism 40 can also keep the chain 32 stationary relative to the first blower 20.

[0062] In this embodiment, the driving mechanism 40 drives the chain 32 to move, thereby driving the first sprocket 30 and the second sprocket 31 to rotate. The rotation of the first sprocket 30 can drive the first connecting member 21 to rotate, and further drive the second blower 22 to rotate relative to the first blower 20. When the second blower 22 rotates to the position, the driving mechanism 40 can be used to keep the chain 32 stationary relative to the first blower 20, so that the first blower 20 and the second blower 22 are relatively stationary.

[0063] In one embodiment, the driving mechanism 40 includes a pushing block 41 and a second connecting member 42.

[0064] The pushing block 41 is slidably arranged below the first blower 20, and the pushing block 41 can slide along the length direction of the first blower 20. Specifically, a first suction cylinder 25 is arranged below the first blower 20, a second suction cylinder 26 is arranged below the second blower 22, and the first suction cylinder 25 and the second suction cylinder 26 are connected by a corrugated pipe. A connecting block 27 is arranged between the first suction cylinder 25 and the first blower 20.

[0065] One end of the second connecting member 42 is connected to the pushing block 41, and the other end of the second connecting member 42 is connected to the chain 32.

[0066] In this embodiment, the sanitation worker holds the main body 10 with the right hand and places the left hand on the pushing block 41 below the first hair dryer 20. When the roller 24 touches the ground, the pushing block 41 is used to push the chain 32 to move. When the roller 24 leaves the ground and the sanitation worker lifts the entire portable leaf blower for operation, holding the pushing block 41 with the left hand can support the first hair dryer 20, and at this time, it is more convenient to drive the pushing block 41 with the left hand.

[0067] In one embodiment, the second connecting member 42 is provided with a mounting hole 421.

[0068] The driving mechanism 40 further includes a rack 43, a sliding block 44, a locking block 45 and a locking tooth 46.

[0069] The rack 43 is connected to the first hair dryer 20 and is located between the second connecting member 42 and the first hair dryer 20. The teeth on it face away from the second connecting member 42, and tooth grooves 431 are formed between adjacent teeth thereon. Specifically, the rack 43 is connected to the first hair dryer 20 through a connecting block 27.

[0070] One end of the sliding block 44 slides through the mounting hole 421 and is located below the rack 43. The locking block 45 is connected to the end of the sliding block 44, and the locking block 45 is located between the rack 43 and the first hair dryer 20. The locking tooth 46 is connected to the locking block 45, and the locking tooth 46 can be inserted into the corresponding tooth groove 431. In addition, both the locking tooth 46 and the teeth on the rack 43 include tooth arms with interconnected tooth ends. The tooth arms are rectangular parallelepipeds, and the tooth ends are triangular prisms. When the locking tooth 46 is inserted into the tooth groove 431, the tooth arm of the locking tooth 46 fits with the tooth arm of the tooth on the rack 43. More than one locking tooth 46 is provided.

[0071] In this embodiment, push the sliding block 44 towards the first hair dryer 20. At this time, the locking tooth 46 on the locking block 45 at the end of the sliding block 44 disengages from the tooth groove 431 on the rack 43, so that the second connecting member 42 can slide relative to the rack 43, that is, the second connecting member 42 and the pushing block 41 can slide relative to the first hair dryer 20, and at this time the chain 32 can move. The sanitation worker pulls the sliding block 44 to move it away from the first hair dryer 20, and the locking tooth 46 is inserted into the tooth groove 431, which can realize the locking of the pushing block 41 and the second connecting member 42 on the first hair dryer 20, and the chain 32 remains stationary on the first hair dryer 20.

[0072] In one embodiment, the sliding block 44 is provided with a mounting window 441 along its length direction.

[0073] The driving mechanism 40 further includes a limiting rod 47, a limiting ring 48 and a spring 49.

[0074] The limiting rod 47 has its two ends respectively connected to the inner walls on both sides of the installation window 441, and its axial direction is the same as the sliding direction of the sliding block 44. The limiting ring 48 is slidably sleeved on the limiting rod 47, and the limiting ring 48 is connected to the second connecting member 42. The spring 49 is sleeved on the limiting rod 47, and the two ends of the spring 49 are respectively connected to the limiting ring 48 and the inner wall of the installation window 441.

[0075] In this embodiment, when the sanitation worker pushes the sliding block 44 to slide in the installation hole 421, the spring 49 is stretched or compressed, so that the sliding block 44 has a tendency to reset. Once the sanitation worker releases the sliding block 44, the sliding block 44 resets, causing the locking tooth 46 to re-insert into the tooth groove 431, completing the locking of the chain 32 and the second connecting member 42.

[0076] In the description of the present invention, a large number of specific details are set forth. However, it can be understood that the embodiments of the present invention may be practiced without these specific details. In some instances, well-known methods, structures, and technologies are not shown in detail so as not to obscure the understanding of this description.

[0077] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
