[0025] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] As an embodiment of a walking type electric tool, Figure 1 As shown, the walking type electric tool is a snow blower 100, and specifically, the snow blower 100 is a hand-push snow blower.

Optionally, the power supply assembly 12 includes at least one battery pack 121, and the battery pack 121 includes a lithium battery cell for storing electrical energy arranged inside the battery pack housing. The housing is formed with a battery compartment, and the battery pack is installed in the battery compartment. In some embodiments, the nominal voltage range of the battery pack is: 10V~60V.

[0029] The walking assembly 13 includes a walking wheel 131 and a walking motor 132 for driving the walking wheel. The number of the walking wheels is 2, and the number of the walking motor 132 can be one, for driving two walking wheels at the same time; the number of the walking motor 132 can also be 2, for driving two walking wheels respectively.

[0030] The snow-clearing assembly 14 includes a snow-clearing paddle 141 and a snow-clearing motor 142 for driving the snow-clearing paddle 141, and the snow-clearing motor 142 is contained in the housing 111. The snow-clearing paddle 141 is a functional element of the snow-clearing machine 100, and is used to stir the snow on the ground. The snow-clearing assembly 14 also includes a snow-clearing bucket 144 and a propeller 145, and the snow-clearing motor 142 is also used to drive the propeller 145 to work. The snow-clearing bucket 144 is used to accommodate the propeller 145, and the snow-clearing paddle 141 rotates in the snow-clearing bucket 144. The snow-clearing bucket 144 includes two side walls 144a that are substantially perpendicular to the ground and parallel to each other, and the snow-clearing paddle 141 is installed between the two side walls 144a. The propeller 145 is installed inside the snow sweeping bucket, at the rear side of the snow sweeping paddle 141. Under the action of the snow sweeping paddle 141, snow enters the snow sweeping bucket 144 from the snow inlet (not shown) of the snow sweeping bucket, and is further acted upon by the propeller 145 and discharged from the snow outlet 142b to the snow throwing device 15. The snow throwing device 15 is used to throw the snow to a distant place. The snow throwing device 15 includes a snow throwing trough 151 installed at the snow outlet 144b of the snow sweeping assembly 14, and is rotatably connected to the snow sweeping assembly 14.

[0031] refer to Figures 2 to 3 An operating device 16 of one embodiment is shown, and the operating device 16 includes a connecting rod 161 connected to the housing 11, a power switch 162 (lock-off), a handle 163, a self-propelled trigger 164, a start trigger 165 (Auger), a self-propelled speed regulating assembly 166, a snowplow speed regulating assembly 167, and a snow throwing trough adjusting assembly 168. The snow throwing trough adjusting assembly 168 and the steering part adjusting assembly 169 are respectively used to adjust the position of the snow throwing trough 151 and the position of the steering part 152 of the snow throwing device 15. Among them, the two handles 163 are respectively arranged on the left and right sides. In order to facilitate the user's holding, the handles 163 are tilted outward and downward relative to the operating device 16. The self-propelled trigger 164 and the start trigger 165 are respectively connected to the two handles 163. For the convenience of explanation, as shown in FIG. Figure 3 As shown, the left and right directions are set according to the position where the user faces the operating device 16 to operate the snow blower 100. Specifically, in this embodiment, the left trigger is the self-propelled trigger 164, and the right trigger is the start trigger 165, but the absolute positions of the self-propelled trigger 164 and the start trigger 165 are not limited. The self-propelled trigger 164 and the start trigger 165 both have a released state and a triggered state. Triggering the self-propelled trigger 164 controls the second motor 132 to start, and triggering the start trigger 165 controls the first motor 142 to start. Figure 2 and Figure 3The self-propelled trigger 164 is in a released state, and the start trigger 165 is in a triggered state. When the self-propelled trigger 164 and the start trigger 165 are in the triggered state, they are at least partially attached to the handle 163. In fact, the user can hold the handle 163 with one hand while keeping the self-propelled trigger 164 or the start trigger 165 in the triggered state. That is, the operating device 16 includes: a first trigger mechanism, such as the power switch 162, which can be operated to be triggered; a second trigger mechanism, such as the start trigger 165, which can be operated to be triggered.

[0032] like Figure 4 As shown, in some embodiments, the operating device 16 and the tool body 11 are detachably connected. Therefore, the operating device 16 has a connection state located on the tool body 11 and a separation state separated from the tool body 11. When the operating device 16 is connected to the tool body 11 (connection state), it communicates with the tool body 11 via wired data to control the operation of the snowplow 100; when the operating device 16 is separated from the tool body 11 (separation state), it communicates with the tool body 11 via wireless data to control the operation of the snowplow 100. Specifically, when the operating device 16 is separated from the tool body 11, the user can remotely control the snowplow 100 within a preset range through the operating device 16 to perform operations, including: starting and shutting down the snowplow 100, moving the snowplow 100, adjusting the speed of the snowplow paddle and the snow throwing chute. When the distance between the operating device 16 and the tool body 11 exceeds the preset range, the operating device 16 cannot control the operation of the snowplow 100, and the snowplow 100 shuts down after a preset time. This makes it easier for users to use the tool and improves the operability of the walking electric tool.

[0033] refer to Figure 5 and Figure 6 As shown, as a schematic diagram of a partial circuit system 200 of a snowplow 100 and a circuit system 300 of an operating device 16 as an embodiment, the snowplow 100 also includes a main body interface 21, a power circuit 22, a first control module 23, a first wired communication module 24, and a first wireless communication module 25.

[0034] The main body interface 21 is provided on the tool body 11. In some embodiments, the main body interface 21 is formed on the housing 111 and is used to access the operating device 16. The operating device 16 also includes an operating interface 31, and the operating interface and the main body interface 21 can be connected via a cable. In other embodiments, the operating interface and the main body interface 21 are adapted to enable the operating device 16 to be directly attached to the tool body 11. Usually, a connecting portion is provided on the operating device 16, and a matching portion is provided on the tool body 11. In some embodiments, the connecting portion forms a guide groove, and the matching portion forms a guide rail, which is used in conjunction with the guide groove so that the operating device 16 can be slidably connected to the tool body 11 along the slide rail. In addition, the main body interface 21 includes at least a first communication terminal 211, and the operating interface includes at least a second communication terminal 311. When the operating device 16 is connected to the tool body 11, the first communication terminal 211 and the second communication terminal 311 are electrically connected to realize wired data communication between the operating device 16 and the tool body 11.

[0035] The power supply circuit 22 is connected to the first control module 23, and is used to convert the electric energy from the power supply component 12 into electric energy that can be used by the first control module 23 and other circuit components. For example, in some embodiments, the power supply circuit 22 reduces the voltage output by the power supply component 12 to 15V to power the first control module 23, and reduces the voltage output by the power supply component 12 to 3.2V to power other power modules. The power supply circuit 22 may include a DC-DC conversion chip.

[0036] The first control module 23 is used to control the operation of the snowplow 100. In some embodiments, the first control module 23 is used to control at least the operation of the travel motor 132.

The second drive circuit 27 is connected to the winding of the snowplow motor 142 to drive the operation of the rotor of the snowplow motor 142. Taking the first drive circuit 26 as an example, the first drive circuit 26 includes switch elements Q1, Q2, Q3, Q4, Q5, and Q6, and the switch elements Q1~Q6 can be selected from field effect transistors, IGBT transistors, etc. For the field effect transistor, the gate end of each switch element is electrically connected to the drive signal output end of the first control module 23, and the drain or source of each switch element is electrically connected to the winding of the travel motor 132. The switch elements Q1~Q6 change the on state according to the drive signal output by the first control module 23, thereby changing the voltage state of the power supply component 12 loaded on the winding of the travel motor 132, and driving the travel motor 132 to operate.

[0038] The first wireless communication module 25 is connected to the first control module 23, and the first wireless communication module 25 transmits control signals to the first control module 23. In this embodiment, when the operating device 16 is separated from the tool body 11, the first wireless communication module 25 is communicatively connected to the operating device 16 to receive the control signal of the operating device 16, and transmits the control signal to the first control module 23 to control the operation of the travel motor 132 and the snowplow motor 142. During the operation of the snowplow 100, when the distance between the operating device 16 and the tool body 11 exceeds the preset range, the first wireless communication module 25 does not receive the control signal of the operating device 16 within the preset time, and the operating device 16 will send a stop signal to the first control module 23 to control the snowplow 100 to stop.

[0039] The first wired communication module 24 is connected between the main body interface 21 and the first control module 23. Specifically, the first wired communication module 24 is connected between the first communication terminal 211 and the first control module 23 to transmit wired communication signals. In this embodiment, when the operating device 16 is connected to the tool body 11, the operating device 16 sends a control signal to the first wired communication module 24, and the first wired communication module 24 transmits the control signal to the first control module 23 to control the operation of the travel motor 132 and the snow-clearing motor 142. The first wireless communication module 25 is a wireless data transmission radio or a Bluetooth module.

[0040] The first control module 23 is configured to: turn off the first wireless communication module 25 when the operating device 16 is connected to the tool body 11, disconnect the communication connection between the first wireless communication module 25 and the operating device 16, receive a control signal from the first wired communication module 24 and send a first drive signal to the first drive circuit 26 according to the control signal to control the operation of the travel motor 132 and send a second drive signal to the second drive circuit 27 to control the operation of the snowplow motor 142.

In this embodiment, the operation unit 32 can detect state changes or signal changes of the connecting rod 161, the power switch 162, the handle 163, the self-propelled trigger 164, the start trigger 165, the self-propelled speed adjustment component 166, the snow paddle speed adjustment component 167, the snow throwing chute adjustment component 168, the steering part adjustment component 169, etc. For example, the user triggers the start trigger 165, and the operation unit 32 detects that the start trigger 165 is in the triggered state, thereby outputting a start control signal. When the user releases the start trigger 165, the operation unit 32 detects that the start trigger 165 is in the released state, and the operation unit 32 outputs a stop control signal. When the user operates the snow throwing adjustment component 168 or the steering part adjustment component 169, the operation unit 32 outputs an adjustment signal by detecting the position change of the snow throwing adjustment rod 168 or the steering part adjustment rod. The operation unit 32 may include one or a combination of a signal switch, a pressure sensor, and a Hall sensor.

[0043] The battery unit 33 is connected to the second control module 34, and is used to provide power for the second control module 34 and other circuit components, such as the operating unit 32, the second wired communication module 36, and the second wireless communication module 35. In some embodiments, the battery unit 33 provides a 15V voltage to the second control module 34, and the battery unit 33 can also provide a 3.2V voltage to power other circuit components. The battery unit 33 can be in the form of a button battery, a dry cell, etc., which can reduce the weight while ensuring power supply to facilitate user portability and operation.

[0044] The second control module 34 is connected to the operating unit 32 and is used to transmit a control signal to the second wired communication module 36 or the second wireless communication module 35.

[0045] The second wireless communication module 35 is communicatively connected to the first wireless communication module 25. Specifically, when the operating device 16 is separated from the tool body 11, that is, when the operating device 16 is in a separated state, the second wireless communication module 35 wirelessly communicates with the first wireless communication module 25 to transmit control signals to the first control module 23. The second wireless communication module 35 may be a wireless data transmission radio or a Bluetooth module.

[0046] The second wired communication module 36 is connected between the operation interface 31 and the second control module 34, specifically, the second wired communication module 36 is connected between the second communication terminal 311 and the second control module 34 to transmit control signals. In this embodiment, when the operation device 16 is connected to the tool body 11, that is, when the operation device 16 is in a connected state, the second wired communication module 36 and the first wired communication module 24 communicate by wire, and transmit the control signal from the second control module 34 to the tool body 11, that is, transmit the control signal to the first control module 23 through the main body interface 21 and the first wired communication module 24, and control the operation of the travel motor 132 and the snow-clearing motor 142. Specifically, the second wired communication module 36 transmits the control signal of the second control module 34 to the first communication terminal 211 to transmit the control signal to the first control module 23, and control the operation of the travel motor 132 and the snow-clearing motor 142.

In some embodiments, the power supply component 12 provides electrical energy to the battery unit 33 to charge the battery unit 33. In addition, the power supply component 12 also provides electrical energy to the second control module 34 and other circuit components of the operating device 16. In some embodiments, when the operating device 16 is connected to the tool body 11, the power supply component 12 charges the battery power source and supplies power to the operating device 16. When the operating device 16 is separated from the tool body 11 , the battery unit 33 provides power to the operating device 16 .
