The control assembly is used for controlling the mower 100, and besides the starting trigger 410, the control assembly further comprises a starting switch 46, the starting switch 46 can be controlled by the starting trigger 410 to start the driving motor, the starting switch 46 is electrically connected with the driving motor, and the starting switch 46 is arranged in the handle 4. In this embodiment, the activation switch 46 is housed in the housing of the handle 4 at the other end of the activation trigger 410 remote from the pivot shaft 43. In the normal state, the elastic member 44 is naturally located between the base 431 of the pivot 43 and one end of the pivot 43, and the activation trigger 410 is suspended outside the housing of the handle 4 without contacting the activation switch 46. When it is desired to activate the drive motor to provide forward power to the mower 100, the user grasps the grip 41 by hand and presses the activation trigger 410 with the fingers of the four fingers pointing up, causing it to pivot upward against the tension of the resilient member 44, thereby activating the activation switch 46. During the forward propulsion of the mower 100, the user must hold the start trigger 410 in order to keep the start switch 46 on, and once the user releases his hand, the start trigger 410 will return under the force of the elastic member 44 to disconnect the start switch 46. Such operation is also a safety concern because the working environment of the mower 100 is typically on grass, which typically has children, small animals, and if the mower 100 is left to walk straight ahead without a person, a safety hazard is likely to occur.
It is worth mentioning that the pivot 43, the elastic member 44 and the activation switch 46 are also provided in two corresponding to the grip portion 41, the connecting portion 45 and the activation trigger 410, and are also symmetrical about the symmetry plane. In general, the user grips the grips 41 with both hands and then activates the trigger 410, but in the present embodiment, the user can obtain forward power to the lawn mower 100 by gripping one of the grips 41 with one hand and activating the trigger 410, so that the user with left-handed operation is facilitated, and the user has an opportunity to make a free hand for answering a call or performing other operations while pushing the lawn mower 100.
Referring to fig. 4 and 6, the hand-push type electric tool further includes an operation platform 5 connected to the end of the push rod 3, the control assembly includes other control structures, such as a speed regulating member 51, disposed on the operation platform 5, and the speed regulating member 51 controls the operating speed of the driving motor. In the present embodiment, the speed regulation member 51 is provided in the form of a speed regulation knob, and the user can adjust the forward speed of the lawn mower 100 by rotating clockwise or counterclockwise. The speed adjusting member 51 is electrically connected to the driving motor.
With continued reference to fig. 2, the mower 100 further comprises a working attachment 7 and a working motor, in the preferred embodiment the working attachment is a mowing blade 7, the chassis 1 is formed with a cutting cavity 12, the cutting cavity 12 accommodates the mowing blade, and the mowing blade 7 rotates within the cutting cavity 12. The working motor drives the mowing blade 7 to perform a mowing task. Of course, when the hand-propelled power tool is a snow blower, the working attachment is a snow chopper. In addition, the chassis 1 further comprises an air duct 11 arranged around the cutting cavity 12, the air duct 11 is of a turbine type, the small diameter of the air duct 11 is communicated with the cutting cavity 12, and the large diameter of the air duct is communicated with a grass collecting box (not shown in the figure). When the grass cutting blade 7 is driven to rotate by the working motor, negative pressure is formed in the cutting cavity 12, so that cut grass scraps are sucked into the cutting cavity 12, enter the air duct 11 along with the small diameter, and then enter the grass collecting box along with the large diameter when the air duct 11 spirals.
The working motor (not shown) may be an electric motor powered by electric power or an internal combustion engine powered by fuel combustion. The chassis 1 carries a working motor. In the preferred embodiment, the working motor is an electric motor.
Referring to fig. 3, the mower 100 further comprises a battery pack for supplying power to the working motor and also to the driving motor. In other embodiments, the working attachment 7 may be driven by a drive motor without providing a working motor. In this embodiment, the battery pack receiving case 8 and the battery pack may be integrally detachable from the chassis 1 of the lawn mower 100, and the battery pack receiving case 8 includes a cover to protect the battery pack from rainwater.
Referring to fig. 3-6, the control assembly of the mower 100 further comprises a working trigger 6 for starting the working motor, the working trigger 6 being disposed on the side of the handle 4 adjacent to the push rod 3, as before, the working trigger 6 also supports one-handed operation, i.e., may be disposed only on the front side of the left grip 41 or the right grip 41 adjacent to the push rod 3. However, in the present embodiment, the working trigger 6 is of an integral frame type structure, the working trigger 6 includes a support portion 61, the support portion 61 is rotatably supported in the housing of the operation platform 5, and the working trigger 6 is rotatable toward the handle 4 about the support portion 61 as a pivot axis. In the present embodiment, a reset element is provided between the support 61 and the housing of the operating platform 5, which reset element has a tendency to reset the working trigger 6 in the direction away from the handle 4.
The control unit further includes a drive switch (not shown) that contacts the operating trigger 6, and is triggered when the operating trigger 6 is rotated about the pivot shaft (support portion 61) to a position close to the handle 4, and is housed in the operating platform 5.
The grip portion 41, the activation trigger 410, and the working trigger 6 described above can be gripped simultaneously by a single hand of the user. In this way, when the user grips the grip 4 with the palm, the user grips the operating trigger 6 and the actuating trigger 410 with the fingers while holding the grip 41 with the palm, so that the lawnmower 100 can move toward the target lawn at a constant speed and cut grass while moving forward. The user can hold the mobile phone by one hand to operate two mutually independent actions, so that the user can conveniently leave the other hand to answer the call or do other things. Of course, it is not necessary to operate both the working trigger 6 and the start trigger 410 simultaneously, such as when a return is required to complete a mowing operation, only the start trigger 410 needs to be operated to return the mower 100 to a storage compartment with less effort, or in a relatively flat area, only the working trigger 6 needs to be operated to perform a mowing operation.
The mower 100 further includes a main switch 55 provided on the operation platform 5, and the working trigger 6 is configured to activate the working motor when the main switch 55 is turned on. The mowing blade 7 must perform mowing operation when the main switch 55 and the working trigger 6 are simultaneously triggered, which is required for safety, and there are different options whether the start trigger 410 is triggered when the main switch 55 is turned on.
The operation platform 5 is further provided with an illumination switch, in the present embodiment, the illumination switch is an illumination toggle button 57, and the illumination toggle button 57 is electrically connected to an illumination lamp disposed in front of the lawn mower 100, and is used for controlling the illumination lamp to be turned on and off, so that the illumination area is enlarged by using the illumination lamp under a dark visual field condition, and the mowing operation is continuously completed.
The operation platform 5 is further provided with a status display screen 53, and the status display screen 53 indicates the residual capacity, the motor temperature, the fault alarm and other conditions of the mower 100. The status display 53 facilitates the user to intuitively grasp the overall situation of the lawnmower 100 and to make appropriate adjustments in time according to the abnormality.
In summary, the present invention has been described with reference to the dc mower 100 as an example of a push-type electric tool, and the structure of the handle 4 of the mower 100 is greatly different from the prior art, so as to avoid the risk of sudden advance of the mower caused by the unintentional triggering of the trigger 410, and in addition, the handle 4 is designed to be compact, and can be operated with one hand or held with two hands, thereby improving the accessibility of the whole mower and enhancing the user experience. Of course, all the structures and the advantages thereof described above are equally applicable when the hand-push type electric tool according to the present invention is a snow blower.
The present invention is not limited to the above-described embodiments. It will be readily appreciated by those skilled in the art that many alternatives to the hand propelled power tool of the present invention are possible without departing from the spirit and scope of the invention. The protection scope of the present invention is subject to the content of the claims.
