Without further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or device comprising that element.

[0029] In this application, the term "and/or" is a kind of association relationship describing the relationship between associated objects, which means that there can be three kinds of relationships. For example, A and/or B can indicate that A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" in this application generally indicates that the contextual associated objects belong to an "and/or" relationship.

[0030] In this application, the terms "connection", "combination", "coupling" and "installation" may be direct connection, combination, coupling or installation, and may also be indirect connection, combination, coupling or installation.

In addition, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, and may include electrical connections or couplings.

[0031] In this application, it is to be understood by those skilled in the art that a relative term (such as "about", "approximately", and "substantially") used in conjunction with quantity or condition includes a stated value and has a meaning dictated by the context. For example, the relative term includes at least a degree of error associated with the measurement of a particular value, a tolerance caused by manufacturing, assembly, and use associated with the particular value, and the like. Such relative term should also be considered as disclosing the range defined by the absolute values of the two endpoints. The relative term may refer to plus or minus of a certain percentage (such as 1%, 5%, 10%, or more) of an indicated value. A value that did not use the relative term should also be disclosed as a particular value with a tolerance. In addition, "substantially" when expressing a relative angular position relationship (for example, substantially parallel, substantially perpendicular), may refer to adding or subtracting a certain degree (such as 1 degree, 5 degrees, 10 degrees or more) to the indicated angle.

[0032] In this application, those skilled in the art will understand that a function performed by an assembly may be performed by one assembly, multiple assemblies, one member, or multiple members.

The auger 22 is mounted on the rotating shaft 21, and the snow sweeping motor drives the rotating shaft 21 to rotate and thus drives the auger 22 to rotate to sweep the snow on the ground. A connector may be a bearing, an inner ring of the bearing is connected to the rotating shaft 21, and an outer ring of the bearing is connected to the body housing 11. The handle 3 is for a user to hold and connected to the body 1. In a traveling direction of the snow thrower, the handle 3 is disposed behind the body 1, and the handle 3 is held to control the traveling direction of the snow thrower.

In this example, the control module 5 is disposed on the handle 3. In some examples, the control module 5 is disposed on the body 1.

[0041] As shown in FIGS. 2 and 3, the operating device 6 is configured to be operated by the user to send a temperature control signal to a wireless communication module 7 when separated from the snow thrower, and the wireless communication module 7 is configured to transmit the temperature control signal to the control module 5. The control module 5 is switched to the power-on state according to the temperature control signal, and the control module 5 in the power-on state controls the temperature of at least part of the snow thrower.

The temperature control signal may be directly forwarded by the wireless communication module 7 to the control module 5 or may be sent to the control module 5 after being processed by the wireless communication module 7, which is not limited here as long as the temperature control signal enables the user to remotely control the temperature of part of the snow thrower to increase or decrease. In some examples, the operating device 6 may be disposed on the snow thrower or separated from the snow thrower. The user may control the temperature of at least part of the snow thrower at a short distance and/or at a long distance through the operating device 6.

[0042] In some examples, the snow thrower further includes a visual display device 8 and a button assembly 9, where the visual display device 8 and the button assembly 9 are disposed on the body 1 or the handle 3. The visual display device 8 is configured to display some information about a working state of the snow thrower, making it easier for the user to learn the working state of the snow thrower in time. The button assembly 9 includes functional operating members such as a power switch, a self-moving trigger, and a start-up trigger.

[0043] When the control module 5 is in the power-on state, the temperature of one or more of the visual display device 8, the button assembly 9, the handle 3, and the working assembly 2 is controlled through the operating device 6, so as to prevent the above parts from freezing that affects the normal operation of the snow thrower. Moreover, the pre-heating of the above parts can be remotely controlled through the operating device 6, and the user does not need to wait outdoors, thereby shortening the time for which the user works outdoors.

[0044] In some other examples, the heating is not limited to the visual display device 8, the button assembly 9, the handle 3, and the working assembly 2 of the snow thrower, and other parts of the snow thrower that are likely to freeze or fog may also be heated, which is not specifically limited here.

[0045] The snow thrower further includes a temperature adjustment device 10, the temperature adjustment device 10 is separately disposed on one or more of at least part of the visual display device 8, at least part of the button assembly 9, at least part of the handle 3, and at least part of the working assembly 2, and the control module 5 is configured to control the temperature of the temperature adjustment device 10. After the operating device 6 sends the temperature control signal to the wireless communication module 7, the wireless communication module 7 transmits the temperature control signal to the control module 5, and the control module 5 controls the temperature of the temperature adjustment device 10 to be the temperature set by the user through the operating device 6. In this manner, the user adjusts the temperature of at least part of the snow thrower by adjusting the temperature of the temperature adjustment device 10. The temperature adjustment device 10 may be a heating wire, or the temperature may be adjusted in one or more manners of electromagnetic heating, electric resistance heating, infrared light heating, and airstream flowing, which is not specifically limited here. In this example, the temperature adjustment device 10 is the heating wire, and the heating wire is wound round part of the handle 3.

[0046] In some examples, as shown in FIGS. 5 and 6, the visual display device 8 includes a display screen 81 configured to display information. The temperature of at least part of the visual display device 8 is adjustable, that is, the preceding temperature adjustment device 10 may be added on the outer side or the inner side of the visual display device 8 to heat the visual display device 8, so as to prevent the visual display device 8 from lagging in a cold environment and effectively prevent the display screen 81 from fogging that affects the viewing of information by the user.

In some examples, the PCB 814 may be disposed at other positions.

[0049] In some examples, as shown in FIG. 7, the temperature of at least part of the working assembly 2 is adjustable, so as to prevent the working assembly 2 from freezing in the cold environment, which affects the normal use of the snow thrower.

[0050] The rotating shaft 21 is connected to the body housing 11 and the auger 22. The temperature of at least part of the rotating shaft 21 is adjustable, so as to prevent the rotating shaft 21 from freezing that affects the normal operation of the auger 22. The two ends of the rotating shaft 21 are connected to the body housing 11 separately through the connectors. To ensure that the rotating shaft 21 can rotate normally at a low temperature, the temperature of the connector is configured to be adjustable. In some examples, the temperature adjustment device 10 is disposed on the connector to adjust the temperature of the connector. In some examples, the connector is the bearing, and the temperature adjustment device 10 is disposed on the bearing.

[0051] The temperature of at least part of the auger 22 is adjustable. After use of the snow thrower, snow attached to the auger 22 is prevented from freezing in the cold environment, which affects the next use. In some examples, the temperature adjustment device 10 is disposed on a part of the auger 22 where snow is easily accumulated, so as to heat the snow on the auger 22 and prevent freezing.

[0052] The preceding operating device 6 sends the control signal to the control module 5 through the wireless communication module 7. In some examples, still referring to FIG. 2, the wireless communication module 7 includes a Wi-Fi unit, and the operating device 6 sends the temperature control signal to the control module 5 through the Wi-Fi unit, thereby implementing a wireless communication connection between the operating device 6 and the control module 5.

[0053] Referring to FIG. 3, the wireless communication module 7 includes a Bluetooth unit, and the operating device 6 sends the temperature control signal to the control module 5 through the Bluetooth unit, so as to implement a wireless communication connection between the operating device 6 and the control module 5.

[0054] In some other examples, the wireless communication module 7 includes the Wi-Fi unit and the Bluetooth unit, and the operating device 6 may send the temperature control signal to the control module 5 through any one of the Wi-Fi unit and the Bluetooth unit, so as to increase selectivity of a wireless connection between the operating device 6 and the control module 5.

[0055] The operating device 6 sends the temperature control signal to the control module 5 through the wireless communication module 7. In some other examples, the operating device 6 may send, through the wireless communication module 7 and to the control module 5, control signals for controlling components such as the snow sweeping motor and the walking motor or a control signal for adjusting a working mode of the snow thrower.

[0056] The operating device 6 may be a remote control or a smart device such as a mobile phone, a smart watch, a tablet computer, or a computer. The operating device 6 may be mounted on the body 1 of the snow thrower. The operating device 6 has a matching key. Pressing the matching key may enable pairing and connection with the control module 5 of the snow thrower so that the corresponding operation control is performed on the snow thrower.

[0057] Referring to FIG. 4, the preceding control module 5 may control the temperature adjustment device 10 to heat a component provided with the temperature adjustment device 10, such as the handle 3, the visual display device 8, and the working assembly 2. The control module 5 performs information exchange with the wireless communication module 7, and the operating device 6 sends signals to the wireless communication module 7. The energy device 4 powers the control module 5, and the energy device 4 can also power the wireless communication module 7. When the energy device 4 is mounted on the snow thrower but the entire machine is not powered on, the control module 5 is not powered by the energy device 4, and the snow thrower is in a standby state. That is to say, when the snow thrower is in the standby state, the energy device 4 is connected to the snow thrower but does not power parts of the snow thrower excluding the wireless communication module 7. Only the wireless communication module 7 is always in a power-on state to receive an instruction sent by the user, thereby reducing energy consumption. In the standby state, the energy device 4 powers only the wireless communication module 7 to maintain the normal operation of the wireless communication module 7. In this case, the wireless communication module 7 has low energy consumption and can receive, at any time, a signal sent by the operating device 6. After receiving the signal sent by the operating device 6, the wireless communication module 7 wakes up the energy device 4 through the control module 5 so that the parts of the snow thrower excluding the wireless communication module 7 are powered on, thereby achieving convenience, low energy consumption, and environmental friendliness. The control module 5 includes a step-down module. The step-down module is disposed on the PCB 814. The energy device 4 powers at least part of the wireless communication module 7 through the step-down module. The step-down module may reduce a voltage provided by the energy device 4 to a voltage required by the wireless communication module 7. In some examples, the step-down module reduces a voltage of 60 V, 56 V, 48 V, or 40 V, etc. to 5 V, 3.3 V, 2.5 V, or 1.8 V, etc.

[0058] In some examples, the wireless communication module 7 may be powered by a separate second energy device such as a button cell or a dry cell so that the wireless communication module 7 is always in the power-on state.

[0059] As shown in FIG. 8, the control module 5 includes a switchboard 12 and a battery management system 13. The user operates the operating device 6 and sends the signal to the wireless communication module 7 remotely. After receiving the signal sent by the operating device 6, the wireless communication module 7 sends a signal to the switchboard 12. The switchboard 12 grounds an enable pin of the battery management system 13 through an EIA-485 communication protocol or another communication protocol. The battery management system 13 is activated and the snow thrower is powered. The control module 5 controls the temperature of part of the snow thrower to change. In this manner, the temperature of part of the snow thrower is adjusted.

[0060] In this example, a control process for heating the handle 3 is described below. The user operates the operating device 6 and sends the signal to the wireless communication module 7. The wireless communication module 7 sends the signal to the switchboard 12. The switchboard 12 activates the battery management system 13, and the battery management system 13 makes the PCB 814 powered on. The PCB 814 converts a large voltage provided by the energy device 4 into a small voltage through the step-down module and increases the temperature of the temperature adjustment device 10. The snow thrower includes a first temperature sensor 14. The first temperature sensor 14 is disposed on the switchboard 12. The first temperature sensor 14 detects an ambient temperature, and the control signal is sent to the PCB according to the detected ambient temperature. When the temperature is relatively low, the PCB 814 controls the temperature adjustment device 10 heated with relatively large heating power. When the temperature is relatively high, the PCB 814 makes the temperature adjustment device 10 heated with relatively small heating power. In this example, the heating power includes P1, P2, P3, and P4, where P1 > P2 > P3 > P4. When the temperature is lower than -10 °C, the heating power is P1. When the temperature is higher than or equal to -10 °C and lower than 0 °C, the heating power is P2. When the temperature is higher than or equal to 0 °C and lower than 15 °C, the heating power is P3. When the temperature is higher than or equal to 15 °C, the heating power is P4. The control module 5 includes the temperature sensor for detecting the temperature, thereby improving heating efficiency and saving energy.

[0061] The snow thrower includes a temperature switch 15. The temperature switch 15 is disposed in a circuit of the temperature adjustment device 10. The temperature switch 15 detects the temperature of the temperature adjustment device 10 and controls, according to the temperature of the temperature adjustment device 10, the circuit to be connected or disconnected. When the temperature of the temperature adjustment device 10 is higher than a preset temperature, the temperature switch 15 turns off. When the temperature of the temperature adjustment device 10 is higher than 50 °C, the temperature switch 15 turns off, and the temperature adjustment device 10 is no longer heated. In some examples, the preset temperature is higher than or equal to 30 °C and lower than or equal to 70 °C. When the temperature of the temperature adjustment device 10 is higher than 40 °C, the temperature switch 15 turns off, and the temperature adjustment device 10 is no longer heated. In some examples, when the temperature of the temperature adjustment device 10 is higher than 30 °C, the temperature switch 15 turns off, and the temperature adjustment device 10 is no longer heated. In some examples, when the temperature of the temperature adjustment device 10 is higher than 60 °C, the temperature switch 15 turns off, and the temperature adjustment device 10 is no longer heated. In some examples, when the temperature of the temperature adjustment device 10 is higher than 70 °C, the temperature switch 15 turns off, and the temperature adjustment device 10 is no longer heated. In some examples, the temperature switch 15 detects the temperature of the handle 3.

[0062] In some examples, a second temperature sensor is disposed near the temperature adjustment device 10. The second temperature sensor is connected to the switchboard 12 or the PCB 814 and detects the temperature of the temperature adjustment device 10. When the second temperature sensor detects that the temperature near the temperature adjustment device 10 is higher than 50 °C, the PCB 814 stops the power supply to the temperature adjustment device 10. A maximum heating temperature is set for the temperature adjustment device 10 through the temperature switch 15 or the second temperature sensor, thereby improving safety and preventing the user from being scalded.

[0063] The basic principles, main features, and advantages of the present application are shown and described above. It is to be understood by those skilled in the art that the preceding examples do not limit the present application in any form, and all technical solutions obtained through equivalent substitutions or equivalent transformations fall within the scope of the present application.
