DETAILED DESCRIPTION OF THE INVENTION

[0021] To make technical means, creative features, achieved objectives and effects of the present disclosure easy to understand, a specific elaboration of the present disclosure is made in the following embodiments with reference to the accompanying drawings.

[0022] Referring to FIG. 1, FIG. 2 and FIG. 3, a leaf blower 5 is illustrated, which includes structures of a conventional leaf blower such as a machine head 1, an air inlet channel 2, and a leaf collection bag 3, etc. The machine head 1 communicates with the air inlet channel 2, and the machine head 1 is internally provided with a fan blade for smashing leaves and a motor driving the fan blade to rotate. A lower end communicating with an inner cavity of the machine head 1 is connected to the leaf collection bag 3. As an improvement of the present disclosure, a side of the air inlet channel 2 is provided with an opening 4 which is provided with a collecting box 5 used for collecting heavier small stones and small animals sucked by the leaf blower into the air inlet channel 2. Under the action of gravity, these heavier small stones and small animals may fall into the collecting box 5. Therefore, the collecting box 5 is arranged at the lower end of the air inlet channel 2 to prevent things in the collecting box 5 from being sucked into the air inlet channel 2 again. The upper end and the lower end of the opening 4 are respectively provided with a first baffle 61 and a second baffle 62, and the first baffle 61 and the second baffle 62 are integrally-molded with the air inlet channel. A specific location relation between the upper end and the lower end needs to be described here. When an operator uses the leaf blower, the air inlet channel 2 inclines to the ground. That is, by taking the ground as a flat surface, an angle is formed between the air inlet channel 2 and the ground, the upper end of the opening 4 is an end away from the ground, and the lower end of the opening 4 is an end close to the ground. In a vertical direction, the upper end of the air inlet channel 2 is an end away from the ground, and the lower end of the opening 4 is an end close to the ground.

[0023] As an improvement of the present disclosure, the length of the first baffle 61 is not greater than that of the second baffle 62. The first baffle 61 is positioned at the upper end of the opening 4, and the second baffle 62 is positioned at the lower end of the opening 4. After the small stones or small animals fall into the collecting box 5, they are at the lower end of the collecting box 5, such that the small stones or small animals may be prevented from being smashed by the fan blade. Generally, the second baffle 62 is longer than the first baffle 61, or the second baffle 62 is equal to the first baffle 61 in length. Preferably, the second baffle 62 is three times as long as the first baffle 61, which can effectively prevent things in the collecting box 5 from being sucked into the air inlet channel 2 again.

[0024] As another improvement of the present disclosure, an edge of the first baffle 61 and an edge of the second baffle 62 are respectively provided with a first flange 71 perpendicular to the first baffle 61 and a second flange 72 perpendicular to the second baffle 62. That is, the edge of the first baffle 61 is provided with the first flange 71 perpendicular to the first baffle 61, and the edge of the second baffle 62 is provided with the second flange 72 perpendicular to the second baffle 62. Both the first flange 71 and the second flange 72 are perpendicular to an axis direction of the air inlet channel 2, and both the first baffle 61 and the second baffle 62 are parallel to the axis direction of the air inlet channel 2. Presence of the flanges may further prevent things in the collecting box 5 from being sucked into the air inlet channel 2 again. Likewise, the length of the first flange 71 is not greater than that of the second flange 72. Generally, the second flange 72 is longer than the first flange 71, or the second flange 72 is equal to the first flange 71 in length. Preferably, the second flange 72 is twice as long as the first flange 71.

[0025] To clearly see the things in the collecting box 5, the collecting box 5 is made of a transparent material, such that it is convenient to observe and timely dump out the small stones or smaller animals in the collecting box 5, thereby preventing the small stones or smaller animals from being sucked into the air inlet channel 2 again.

[0026] In addition, generally the collecting box 5 is in threaded connection with the air inlet channel 2 by means of a bolt. Specifically, a mounting frame 8 is disposed along a periphery of an edge of the opening 4, and an opening of the collecting box 5 is sleeved on the mounting frame 8. A threaded hole is respectively provided on the collecting box 5 and the mounting frame 8, such that the collecting box 5 may be fixed to the mounting frame 8 by means of a bolt, and thus mounting or dismounting the collecting box 5 is convenient.

[0027] The above are merely preferred embodiments of the present disclosure, but implementations and the scope of protection of the present disclosure are not limited thereto. Those skilled in the art should appreciate that all solutions obtained based on equivalent substitutions and apparent variations by using the specification described and contents illustrated in the present disclosure shall fall within the scope of protection of the present disclosure.
