Fig. 2 is a schematic perspective view of a specific embodiment of the casing of the lawnmower of the present invention.

Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

As shown in FIGS. 1 and 2 , the present invention provides a lawn mower, which includes: a housing 1 , a motor 2 , a blade 3 , and a grass collecting box 4 .

The top surface of the housing 1 is provided with a first grass collection channel 11 and a second grass collection channel 12 , and the motor 2 is located between the first grass collection channel 11 and the second grass collection channel 12 . Wherein, the cut grass can enter the grass collecting box 4 through the first grass collecting channel 11 and the second grass collecting channel 12 .

Specifically, the grass collecting box 4 is detachably installed on the top surface of the housing 1 , and the first grass collecting channel 11 , the second grass collecting channel and the motor 2 are accommodated in the grass collecting box 4 . Installing the grass collecting box 4 on the top surface of the housing 1 increases the height of the grass collecting box 4 and facilitates the installation and disassembly of the grass collecting box 4 . In one embodiment, the grass collecting box 4 can be detachably mounted on the top surface of the housing 1 through buckles.

In addition, in order to facilitate the installation and fixing of the motor 2 , an installation cavity is recessed in the middle position of the top surface of the housing 1 , and the motor 2 is accommodated in the installation cavity.

In order to realize that the broken grass is collected through the first grass collection passage 11 and the second grass collection passage 12, any grass collection passage has an inlet communicated with the housing 1 and communicated with the grass collection box 4 export. Thereby, the cut grass enters the grass collecting box 4 under the guidance of the grass collecting channel for collection.

Further, the outlet of the first grass-collecting passage 11 is set towards the end where the entrance of the second grass-collecting passage 12 is located, and the outlet of the second grass-collecting passage 12 is facing the entrance of the first grass-collecting passage 11 set at one end. Thus, the broken grass discharged from the outlet will slide along the outer wall surface of the grass collection channel under the action of the airflow. When it approaches the outer wall surface of the motor 2, the flow direction of the airflow will change, and the broken grass will rotate accordingly. Finally fall in the grass collecting box 4 under the drive of air-flow.

Therefore, the lawnmower of the present invention adopts a cyclone-type grass collection method, so that the broken grass can be collected into the grass collection box 4 more evenly, avoiding gaps between the broken grass, and improving the grass full rate of the lawn mower. Wherein, the grass full rate refers to the ratio of the volume of the grass in the grass box to the volume of the grass box, that is, under a certain power condition, the grass full rate can reflect the maximum capacity of the grass collected by the grass box. When cutting Grass can no longer enter the grass collection box. At this time, the volume of grass / the volume of the grass collection box = grass full rate.

In a preferred embodiment, in order to facilitate the formation of the cyclone, any grass-collecting channel is arc-shaped, and the height of any grass-collecting channel gradually increases from its inlet to its outlet. At this time, the first grass-collecting channel 11 and the second grass-collecting channel 12 are arranged symmetrically about the center. Thus, the motor 2 and the first grass-collecting channel 11 and the second grass-collecting channel 12 on both sides thereof form a cyclone space for the airflow blown from the outlet.

In order to provide power for collecting broken grass, steam turbines are also arranged in the first grass collecting channel 11 and the second grass collecting channel 12 . The efficiency of collecting broken grass is improved by setting two steam turbines.

The blade 3 is used to cut the lawn, specifically, the blade 3 is located in the housing 1 and is connected to the motor 2 in transmission. In one embodiment, the middle of the blade 3 is in drive connection with the motor 2 through a rotating shaft, and the height of one end of the blade 3 is greater than the height of the other end of the blade 3 . With this arrangement, when the blade 3 rotates once, it can cut at two positions, thereby making the length of cut grass shorter, further improving the grass fullness rate, and reducing the number of times of weeding.

In addition, the mower also includes front wheels 5 and rear wheels 6, wherein the front wheels 5 and rear wheels 6 are mounted on the housing 1 through brackets, and the distance between the rear wheels 6 is larger than the The diameter of front wheel 5 is arranged like this, helps to improve the stability of running when the lawnmower mows.

To sum up, the lawnmower of the present invention adopts the cyclone grass collection method, which is beneficial to the collection of broken grass and has a higher grass full rate. Simultaneously, the lawn mower of the present invention arranges the grass collecting box on the upper part of the casing, which facilitates the installation and disassembly of the grass collecting box.

It will be apparent to those skilled in the art that the invention is not limited to the details of the above-described exemplary embodiments, but that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Accordingly, the embodiments should be regarded in all points of view as exemplary and not restrictive, the scope of the invention being defined by the appended claims rather than the foregoing description, and it is therefore intended that the scope of the invention be defined by the appended claims rather than by the foregoing description. All changes within the meaning and range of equivalents of the elements are embraced in the present invention. Any reference sign in a claim should not be construed as limiting the claim concerned.

In addition, it should be understood that although this specification is described according to implementation modes, not each implementation mode only contains an independent technical solution, and this description in the specification is only for clarity, and those skilled in the art should take the specification as a whole , the technical solutions in the various embodiments can also be properly combined to form other implementations that can be understood by those skilled in the art.
