DETAILED DESCRIPTION
[0030] The following is combined with Figure 1-7The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.
[0031] The embodiment of the present application discloses a grass collecting system for a lawn mower.
[0032] Reference Figure 1 and Figure 2 A grass collecting system for a lawn mower of the present embodiment includes a cover body 1 and a box body 2. The front end of the box body 2 has a grass inlet 23. The top of the box body 2 is provided with an opening 211 and a plurality of air holes 212. The air holes 212 are located on a side of the opening 211 away from the grass inlet 23. The cover body 1 is movably connected to the box body 2. The cover body 1 is used to cover the opening 211 during grass collecting operation.
[0033] Reference Figure 1 and Figure 2 The lawn mower includes a housing 3, a mowing assembly and a handle frame 4. A rotating shaft 11 is fixedly provided at one end of the cover body 1. The rotating shaft 11 is rotatably connected to the handle frame 4 of the lawn mower. A torsion spring 12 is installed on the rotating shaft 11. The torsion spring 12 is used to drive the cover body 1 to always rotate downward toward the side away from the housing 3. Two hooks 213 are provided on the box body 2. The two hooks 213 are respectively located on both sides of the cover body 1 and are used to hang on the rotating shaft 11. After the box body 2 is on the rotating shaft 11, the box body 2 will abut against the housing 3 under the action of gravity. At this time, the grass inlet 23 is facing the mowing assembly, and the box body 2 is in a grass collecting state. At this time, the cover body 1 also abuts against the top surface of the box body 2 under the action of the torsion spring 12, and the opening 211 is completely blocked.
[0034] Reference Figure 1 and Figure 2 The operator can see the grass collection status in the box 2 from the air vent 212. The lawn mower continuously throws the grass clippings into the box 2, and the excess air will come out from the air vent 212. After the box 2 is full of grass, the air vent 212 is blocked. Therefore, the operator can judge the grass collection status in the box 2 by feeling the air outlet size of the air vent 212.
[0035] Reference Figure 2 and Figure 3 , wherein the box body 2 includes an upper cover 21 and a lower cover 22 , the upper cover 21 is buckled on the lower cover 22 , and the hook portion 213 , the opening 211 and the vent hole 212 are all located on the upper cover 21 .
[0036] Reference Figure 2-Figure 6A grass collecting system for a lawn mower in this embodiment further includes a baffle 5 and two detection members 7. A plurality of buckles 214 are provided on the upper cover 21. The plurality of buckles 214 are evenly distributed around the plurality of air holes 212. A plurality of card slots 51 are provided on the baffle 5. The plurality of buckles 214 are snapped onto the plurality of card slots 51. When the baffle 5 is installed on the upper cover 21, the baffle 5 only forms an air outlet gap 6 between the left and right sides and the housing 2. The detection member 7 is provided on the baffle 5. The two detection members 7 are respectively used to detect the gas flow rate passing through the two air outlet gaps 6. The detection member 7 detects the gas flow rate of the two air outlet gaps 6 to determine the grass collecting state in the housing 2.
[0037] Reference Figure 6 and Figure 7 The detection member 7 includes a fixed block 71, a movable block 72, a spring 73 and a wind shield 74. The fixed block 71 is fixedly arranged on the bottom wall of the cover 5. A slide groove 711 is opened at one end of the fixed block 71 toward the outside of the air outlet gap 6. The movable block 72 slides in the slide groove 711 along the air outlet direction. The two ends of the spring 73 are respectively arranged on the bottom wall of the slide groove 711 and the fixed block 71. The wind shield 74 is arranged on the movable block 72. The wind shield 74 is located on the air outlet path of the air outlet gap 6. When the lawn mower stops working or the box body 2 is full of grass during work, the movable block 72 is always located in the air outlet gap 6; when the lawn mower works normally and the box body 2 is not full of grass, the end of the movable block 72 extends out of the air outlet gap 6.
[0038] Reference Figure 6 and Figure 7 As the lawn mower continuously throws the grass clippings into the housing 2, the air passes through the air vents 212 and comes out of the air outlet gap 6. The wind deflector 74 is blown by the wind and drives the movable block 72 to overcome the elastic force of the spring 73 and move out of the air outlet gap 6. The operator can directly see the end of the movable block 72. This indicates that the housing 2 is not full of grass. If the housing 2 is full of grass and the air vents 212 are blocked, the wind deflector 74 can no longer be blown by the wind. Under the action of the spring 73, the movable block 72 returns to the air outlet gap 6, and the operator can no longer see the end of the movable block 72.
[0039] Reference Figure 6 and Figure 7 A prism 721 is provided at one end of the moving block 72 near the outside. When the air vent 212 is normally venting air, the prism 721 extends out of the air outlet gap 6. When the box 2 is full of grass and the air vent 212 cannot vent air normally, the prism 721 is always located in the air outlet gap 6. Since the mowing operation environment is usually open air during the day, the prism 721 can reflect part of the sunlight, appearing brighter and easier for operators to see.
[0040] Reference Figure 3 , Figure 5-Figure 7The air outlet gap 6 is tilted downward. A first handle 24 is provided at the rear end of the box body 2, and a bucket 25 is provided at the front end of the lower cover 22. A cross-shaped anti-slip depression 221 is provided at the bottom end of the lower cover 22. A second handle 13 is provided on the top surface of the cover body 1.
[0041] Of course, the above are only typical examples of the present application. In addition, the present application may have many other specific implementation methods. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present application.
