[0025] In addition, although the terms used in this application are selected from well-known and commonly used terms, some terms mentioned in the specification of this application may be selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant parts of the description of this article.

[0026] Furthermore, it is required that the application be understood not only by the actual terms used but also by the meanings connoted by each term.

[0027] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0028] The embodiment of the present application provides a lawn mower. Figures 1 to 2 The lawn mower 100 provided in the embodiment of the present application includes: a body 110 , a roller brush driver 120 , a roller brush 130 , a cover 140 , a fan 150 and a collector 160 .

[0029] A lawn mower, also known as a weed cutter, lawn mower, or lawn trimmer, is a mechanical tool used to trim lawns, vegetation, and the like. It includes a cutterhead, an engine, and running wheels. For example, the direction of the lawn mower 100 can be manually controlled. Alternatively, the lawn mower 100 can be an intelligent lawn mower, which can move automatically.

[0030] The roller brush driver 120 is provided on the vehicle body 110. The roller brush driver 120 is driven and connected to the roller brush 130 to drive the roller brush 130 to rotate around the horizontal axis 131. The cover 140 is provided on the outer periphery of the roller brush 130, and a spacing area 140a is formed between the cover 140 and the roller brush 130. A feed area 140b and a discharge area 140c are provided at both ends of the spacing area 140a along the circumference of the roller brush 130. The feed area 140b faces the ground, and the discharge area 140c is located above the feed area 140b. The air outlet 151 of the fan 150 is directed toward the top of the discharge area 140c and the feed inlet 161 of the collector 160 in turn, so as to blow the collected materials thrown from the discharge area 140c into the collector 160. The collected materials include grass clippings. In addition, for example, the collected materials may also include fallen leaves.

[0031] In this manner, in the embodiment of the present application, the roller brush driver 120 can drive the roller brush 130 to rotate about the horizontal axis 131, thereby allowing the bottom of the roller brush 130 to roll up grass clippings and, guided by the cover 140, eject them through the discharge area 140c. Furthermore, the air outlet 151 of the fan 150 blows air toward the discharge area 140c, driving the grass clippings toward the feed inlet 161 of the collector 160, whereupon the grass clippings enter the collector 160 through the feed inlet 161. This enables the lawn mower 100 to not only mow grass but also collect grass clippings.

[0032] In some embodiments, the roller brush 130 is a plastic roller brush. Exemplarily, the roller brush 130 includes a base 132 and a plurality of bristles 133 connected to the base 132. The bristles 133 extend radially from the base 132. Exemplarily, the bristles 133 may be nylon. It should be noted that when mowing a lawn, some roots remain. Therefore, to prevent these roots from being damaged by the rotating roller brush 130, the bristles 133 of the roller brush 130 may be nylon.

[0033] In some embodiments, the cover 140 is disposed along the horizontal direction on a side of the horizontal axis 131 that is away from the feed port 161 of the collector 160. Figure 1 The feed port 161 is located on the right side of the horizontal axis 131 , and the cover body 140 is located on the left side of the horizontal axis 131 . In this way, the cover body 140 is located on the side of the horizontal axis 131 away from the feed port 161 of the collector 160 .

[0034] In some embodiments, the cover 140 is vertically arranged at one end away from the feed zone 140b. Figure 1 The top of the cover body 140 is arranged vertically, so that the objects to be collected can be thrown vertically from the discharge area 140 c, making it easier to blow the objects to be collected into the collector 160 .

[0035] In some embodiments, the collector 160 is provided with an air outlet, so that the air pressure in the collector 160 can be consistent with the air pressure of the external environment, thereby facilitating the blowing of the collected material into the collector 160 .

[0036] Exemplarily, the collector 160 is a breathable bag. In some embodiments, the lawn mower 100 further includes a support frame. The support frame is connected to the vehicle body 110. The breathable bag is mounted on the support frame. For example, the support frame can be a metal frame formed by welding metal, or a plastic frame manufactured by injection molding. Thus, by mounting the breathable bag on the support frame, the support frame can be used to support the breathable bag.

[0037] In some embodiments, the lawn mower 100 further includes a flipper 170. The flipper 170 is used to flip the collector 160 to switch between a feeding state and a discharge state. When the collector 160 is in the feeding state, the feed port 161 of the collector 160 faces the air outlet 151 of the fan 150. When the collector 160 is in the discharge state, the feed port 161 of the collector 160 faces the ground.

[0038] Specifically, when the collector 160 is needed to collect the collected material, the flipper 170 can be used to drive the collector 160 to flip so that the feed port 161 of the collector 160 faces the air outlet 151 of the fan 150. When the collected material in the collector 160 needs to be discharged, the flipper 170 can be used to drive the collector 160 to flip so that the feed port 161 of the collector 160 faces the ground. In this way, the collected grass clippings and other materials in the collector 160 can fall to the discharge position under the action of gravity.

[0039] It should be noted that, when the lawn mower 100 includes a support frame, the flipper 170 is drivably connected to the support frame, so that the collector 160 mounted outside the support frame can be flipped together with the support frame by driving the support frame to flip.

[0040] In some embodiments, the distance between the bottom of the roller brush 130 and the ground is greater than or equal to 0.5 mm and less than or equal to 5 mm. For example, the distance between the bottom of the roller brush 130 and the ground can be 1 mm. This prevents the rotating roller brush 130 from damaging the roots of the lawn. It should be noted that those skilled in the art can flexibly adjust the distance between the bottom of the roller brush 130 and the ground according to actual needs, and this will not be listed here.

[0041] In some embodiments, the roller brush driver 120 is connected to a plug connector. The roller brush 130 is plugged into the plug connector. In this way, the roller brush 130 can be plugged into the plug connector to improve the convenience of disassembly and assembly of the roller brush 130.

[0042] To facilitate those skilled in the art to understand the solution provided by the embodiment of the present application, the following briefly introduces how the lawn mower 100 collects grass clippings.

[0043] The lawn mower 100 is provided with a cutter disc, which rotates to cut the grass. Figure 1 As the lawn mower 100 moves to the left, the roller brush 130 rotates clockwise. The bottom of the roller brush 130 rolls up the grass clippings and, guided by the cover 140, throws them upward. Furthermore, the air outlet 151 of the fan 150 blows air upward from the cover 140. This airflow propels the grass clippings toward the feed port 161 of the collector 160, where they enter the collector 160 through the feed port 161.

[0044] After the collector 160 is full, the mower 100 moves to the discharge position. Then, the flipper 170 drives the collector 160 to flip so that the feed port 161 of the collector 160 faces the ground, so that the collected grass clippings in the collector 160 can fall to the discharge position under the action of gravity.

[0045] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0046] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the embodiments of the present application, and the scope of the embodiments of the present application is defined by the appended claims and their equivalents.
