Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The lawn mower of the embodiment is an intelligent robot lawn mower, comprises a battery pack for providing working energy, and further comprises an intelligent control system, and can automatically walk on a lawn and mow the lawn under the unattended condition.
Fig. 1 shows an intelligent lawn mower 100 according to an embodiment of the present invention, where the intelligent lawn mower 100 includes a housing 10, and a receiving cavity is formed in the housing 10, and a plurality of components supported by each other are received in the receiving cavity, and are used to jointly support the implementation of each function of the intelligent lawn mower 100. The housing comprises a housing bottom 12 and an opposite housing top, the housing bottom 12 mounting a cutter 14 and a wheel set 16. In addition, the intelligent mower 100 further has a walking motor, a cutting motor, a battery pack, etc., which are all parts of a common intelligent mower known to those skilled in the art, and which are not the essential point of the present invention, and thus they will not be described in detail herein and are not labeled in the drawings.
A channel 18 is arranged in the accommodating cavity of the intelligent mower 100, one end of the channel 18 is a grass collecting opening 20, the grass collecting opening 20 extends towards the bottom 12 of the housing of the intelligent mower 100, a grass outlet 22 is further arranged on the housing 10 of the intelligent mower 100, and the other end of the channel 18 is connected with the grass outlet 22, which only lists schematic diagrams of the channel 18. A centrifugal fan 24 is also arranged in the channel 18 between the grass collecting opening 20 and the grass outlet 22, the fan 24 is driven by a motor 26, and the motor 26 is powered by a battery pack. When the fan 24 is turned on, an airflow is formed in the passage 18 between the grass collecting opening 20 and the grass outlet 22, and the airflow flows from the grass collecting opening 20 to the grass outlet 22. In this way, when the lawn has fallen leaves in autumn, the fallen leaves on the ground will be sucked into the grass collecting opening 20 and move towards the grass outlet 22 under the action of the airflow when the intelligent lawn mower 100 walks, and the fallen leaves will be broken by the leaf breaking fan 24 when passing through the leaf breaking fan 24 and finally discharged from the grass outlet 22. The fan 24 may be mounted at any position in the channel 18, but in order to increase the suction force and thus obtain a better suction effect, the fan 24 is preferably mounted at the end of the channel 18 near the grass-collecting opening 20. When the fan 24 is installed in the channel 18, it is preferable that the axis X of the rotating shaft of the fan 24 coincides with or is tangent to a center line (not shown) of the channel 18, and the axis X of the rotating shaft coincides with the center line in the present schematic diagram. In practice, the channel 18 may be arranged in a linear or non-linear manner, and the shaft axis X coincides with the center line when the channel 18 is arranged in a linear manner, and the shaft axis X is tangent to the center line when the channel 18 is arranged in a non-linear manner. Such an angular disposition of the sirocco fan 24 in the passage 18 is also intended to increase the suction force of the sirocco fan 24 to obtain a better suction effect.
In this way, the intelligent lawn mower 100 can automatically suck fallen leaves on the ground into the grass collecting opening 20, and the fallen leaves in the channel 18 are smashed by the leaf smashing fan 24 and finally discharged from the grass outlet 22, so that the problem of fallen leaves on the lawn of a user is effectively solved. In the process, the intelligent lawn mower 100 can autonomously complete the processing work of lawn fallen leaves without manual direct control and operation, so that the manual operation is greatly reduced, time and labor are saved, and a user can be really relieved from the labor of lawn care.
As shown in fig. 2, the intelligent lawn mower 100 is detachably mounted with a grass collection box 28, and the grass collection box 28 is used for collecting the crushed grass which is crushed by the blade crushing fan 24 in the channel 18 and discharged from the grass outlet 22. The length of the grass collecting box 28 in the longitudinal direction is 1/4-2/3 of the length of the intelligent mower 100 in the longitudinal direction, so that the stability of the intelligent mower 100 with the grass collecting box 28 mounted and the necessary grass collecting and storing capacity can be well guaranteed. Since the intelligent lawn mower 100 is generally small in size and light in weight, if the grass collecting box 28 is hung too much, the center of gravity of the intelligent lawn mower 100 is unstable when the intelligent lawn mower 100 travels, and conversely, if the grass collecting box 28 is too small, the necessary grass collecting and storing capacity cannot be ensured, and the intelligent lawn mower needs to be frequently disassembled, dumped and installed, which is quite cumbersome, the length of the intelligent lawn mower 100 in the longitudinal direction 1/4-2/3 is selected as the length of the grass collecting box 28 in the longitudinal direction.
The leaf sucking and crushing functions of the intelligent mower 100 solve the problem of leaf falling on the lawn in autumn, great convenience is brought to users, but fertilization on the lawn still needs to be completed by the users themselves. To enable the user to be completely relieved from lawn care, we provide an intelligent lawn mower 100 that is further improved in addition to having leaf-sucking and leaf-breaking functions.
The top of the grass collecting box 28, which is far away from the ground, is provided with a fertilizer adding port 30 for adding fertilizer into the grass collecting box 28, and the fertilizer adding port 30 is positioned at the front end of the grass collecting box 28, which is close to the grass outlet 22 of the intelligent mower 100, on the top of the grass collecting box 28. The bottom of the grass collecting box 28 close to the ground is provided with a fertilizer applying opening 32 for applying fertilizer in the grass collecting box 28 to the ground, and the fertilizer applying opening 32 is positioned at the rear end of the grass collecting box 28, which is far away from the grass outlet 22 of the intelligent mower 100, at the bottom of the grass collecting box 28. The grass collecting box 28 is further provided with a grass collecting opening (not shown), and when the grass collecting opening is mounted on the intelligent mower 100, the grass collecting opening is in butt joint with the grass outlet 22 of the intelligent mower 100, so that the crushed leaves or grass clippings discharged from the grass outlet 22 are collected. In use, when a user adds fertilizer through the fertilizer adding opening 30 at the top of the grass collecting box 28, the leaf crushing fan 24 generates an airflow in the channel 18 after being turned on, the airflow flows from the grass collecting opening 20 to the grass outlet 22, and the airflow flows from the grass outlet 22 to the grass collecting opening 28 and finally flows out from the fertilizer applying opening 32 of the grass collecting box. The fertilizer added into the grass collecting box 28 is driven by the airflow to gradually flow to the fertilizing port 32 and finally flow out of the fertilizing port 32, so that the fertilizer is spread on the lawn on the ground, and the intelligent mower 100 always moves in a defined area, so that the automatic fertilization of the intelligent mower 100 can be realized in the defined lawn area basically, and a good fertilizing effect can be realized. And in addition, the broken leaves or grass scraps collected by the grass collecting box 28 can also be discharged as fertilizer to be scattered on the lawn through the fertilizing opening 32. The fertilizer applying opening 32 of the grass collecting box 28 can be always opened, and the opening or closing of the fertilizer applying opening 32 can be controlled by additionally arranging the inductor 34. When the sensor 34 is arranged in the grass collecting box 28, a corresponding controller (not shown in the figure) needs to be installed on the fertilizer applying port 32, the sensor 34 can control the opening and closing of the fertilizer applying port 32 by sensing the weight of the fertilizer, when the weight of the fertilizer reaches a preset value, the sensor 34 sends a signal to the controller of the fertilizer applying port 32, and the controller opens the fertilizer applying port 32 through corresponding mechanical structures after receiving the signal. Through the design, the intelligent mower 100 has the functions of leaf suction and leaf crushing and better automatic fertilization besides the basic automatic mowing function, so that the client is really relieved from the heavy labor of lawn care.
Referring to fig. 3, the intelligent lawn mower 100 further includes a movable support 36 of the grass collecting box 28 and a switch 38 for controlling the on and off of the fan 24, wherein the movable support 36 includes a hook 40 for hanging the grass collecting box 28. The movable support 36 has a first state in which the grass collecting box 28 is installed and a second state in which the grass collecting box 28 is removed. When the movable support 36 is in the first state, the grass-collecting box 28 is mounted to apply pressure to the movable support 36, and the movable support 36 is pressed to abut against the switch 38 to close the circuit of the fan 24, so that the fan 24 starts to operate when the fan 24 is powered on. When the movable support 36 is in the second state, the originally installed grass collecting box 28 is removed, and the movable support 36 is out of contact with the switch 38 of the broken blade fan 24 under the condition of no force, so as to break the circuit of the broken blade fan 24, and at the moment, the broken blade fan 24 stops running. Due to the design, the operation of the leaf crushing fan 24 can be ensured under the condition that the intelligent mower 100 is prepared to treat fallen leaves of a lawn or fertilize after the grass collecting box 28 is installed, and the operation of the leaf crushing fan 24 can be correspondingly stopped after the grass collecting box 28 is removed, so that the safety of a user can be well ensured, and the damage to the user caused by the contact of the leaf crushing fan 24 which is still in the operation state after the grass collecting box 28 is removed and the user can be prevented. Of course, those skilled in the art will appreciate that other implementations of such a linked switch structure between the grass collecting box 28 and the fan 24 are also possible, and only one specific implementation is listed here, and the linked switch implementation between the grass collecting box 28 and the fan 24 is not limited in the present invention.
