[0038] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the following further elaborates on the present application in conjunction with the attached Figure 1-10 drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] An embodiment of the present application discloses a violent fan.

[0044] Optionally, the power supply port 5 has multiple types. For example, the power supply port 5 includes a USB port, a DC power jack, a Lightning port, etc. Further, the power supply port 5 is also used to charge the violent fan.

[0045] In some other embodiments, a temperature sensor is further installed inside the air duct 2, and the temperature sensor is located at one end of the air duct 2 close to the air inlet 21.

[0046] In some other embodiments, a humidity sensor is further installed inside the air duct 2, and the humidity sensor is located at one end of the air duct 2 close to the air inlet 21.

[0047] In some other embodiments, a motion sensor is further installed inside the holding housing 1, and the motion sensor is used to detect the motion state of the violent fan.

[0048] In summary, on the premise of ensuring the basic functions of the fan, a power supply port is provided on the holding housing of the violent fan, and the power supply port is electrically connected to the battery, so that the fan has the function of external power supply, expanding the functions of the fan.

[0049] The embodiment of the present application discloses a schematic flowchart of a power supply method for a violent fan. Refer to Figure 3 , the method includes: Step S301: In response to a power supply operation, obtain the charging parameters and device type of the target device, where the charging parameters include at least one of the rated charging voltage and the rated charging current.

[0050] The power supply operation refers to an operation that triggers the violent fan to supply power externally. Exemplarily, the power supply operation is that the user uses a data cable to connect the power supply port to the charging port on the target device.

[0051] In some embodiments, a voltage detection circuit is provided inside the violent fan, and the rated charging voltage of the target device can be obtained through the voltage detection circuit.

[0052] In some embodiments, the brute-force fan sends a charging parameter request to the target device. After obtaining the charging parameter request, the target device returns the charging parameters to the brute-force fan. Among them, the brute-force fan and the target device use the same communication protocol.

[0053] Step S302: Set the power supply voltage according to the charging parameters.

[0054] Exemplarily, if the rated charging voltage in the charging parameters is less than the maximum power supply voltage of the brute-force fan, the power supply voltage is set to the rated charging voltage; if the rated charging voltage in the charging parameters is greater than the maximum power supply voltage of the brute-force fan, the power supply voltage is set to the maximum power supply voltage.

[0055] Exemplarily, the power supply voltage is set to the rated charging voltage, and the power supply current of the brute-force fan is detected in real time; when it is detected that the power supply current is less than the rated charging current and the difference between the power supply current and the rated charging current is greater than the preset current difference, the power supply voltage is increased until the difference between the power supply current and the rated charging current is less than the preset current difference; when it is detected that the power supply current is greater than the rated charging current and the difference between the power supply current and the rated charging current is greater than the preset current difference, the power supply voltage is decreased until the difference between the power supply current and the rated charging current is less than the preset current difference.

[0056] Step S303: When the device type is a power storage device type, obtain the remaining power of the target device.

[0057] The device type includes a power storage device type and a non-power storage device type. The power storage device type refers to a device with a structure for storing electric energy inside, and the non-power storage device type refers to a device without a structure for storing electric energy inside. For example, the structure for storing electric energy is a battery.

[0058] Exemplarily, the brute-force fan sends a remaining power request to the target device. After obtaining the remaining power request, the target device returns the remaining power to the brute-force fan.

[0059] Step S304: Set the stop power supply power of the target device according to the battery parameters of the target device, where the battery parameters include the battery capacity and the battery type.

[0060] When the remaining power of the target device is greater than the stop power supply power, the brute-force fan stops supplying power to the target device.

[0061] The battery type includes but is not limited to nickel-metal hydride batteries, nickel-cadmium batteries, lithium-ion batteries, lead-acid batteries, etc. Further, look up the conversion parameter corresponding to the battery type in the first mapping table, where the first mapping table is used to record the correspondence between the battery type and the conversion parameter. For example, when the battery type is a lithium-ion battery, the conversion parameter is 80%.

[0062] In this embodiment, the battery capacity refers to the actual battery capacity of the target device, rather than the calibrated battery capacity. The battery will experience wear and tear due to use, resulting in the actual battery capacity being less than the calibrated battery capacity when the battery leaves the factory.

[0063] Exemplarily, calculate the product of the battery capacity and the conversion parameter to obtain the power-off power.

[0064] Step S305: Calculate the power supply time according to the supply voltage, the remaining power, and the power-off power.

[0065] Exemplarily, calculate the difference between the power-off power and the remaining power to obtain the total power supply provided by the brute-force fan to the target device; calculate the power supply power of the brute-force fan to the target device through the supply voltage; calculate the ratio of the total power supply to the power supply power to obtain the power supply time. Among them, the total power supply is expressed in watt-hours (Wh).

[0066] Step S306: Supply power to the target device according to the supply voltage and the power supply time.

[0067] Exemplarily, within the power supply time, the brute-force fan uses the supply voltage to supply power to the target device.

[0068] In summary, when the brute-force fan supplies power externally, it will adjust the supply voltage and the power supply time according to the device type to achieve intelligent power supply, ensure power supply safety and speed, and will not damage the target device.

[0069] In the following embodiment, in an implementation scenario of the brute-force fan provided in this application, the brute-force fan can supply power to the ignition device on the vehicle. When the weather is cold, the ignition device cannot be used due to the cold. Even if the brute-force fan supplies electrical energy to the ignition device, the ignition device still cannot start. At this time, use the brute-force fan to blow hot air towards the ignition device, thereby increasing the temperature of the ignition device to achieve the normal start of the ignition device. Therefore, this application embodiment discloses a flow schematic diagram of an application method of a brute-force fan. Refer to Figure 4 , the method includes: Step S401: Monitor the supply current of the brute-force fan.

[0070] Optionally, a current detection circuit is installed inside the brute-force fan, and the supply current of the brute-force fan can be detected through the current detection circuit.

[0071] Step S402: In the case where a current mutation occurs in the detected supply current and the current mutation value is within a preset current range, determine whether the target device is in an abnormal working state.

[0072] If the target device is in an abnormal working state, then execute step S403; If the target device is not in an abnormal operating state, then perform steps S404 to S405.

[0073] The preset current range is a preset range, and the endpoints of the preset current range can be adjusted according to actual requirements.

[0074] Exemplarily, when there is a current mutation in the supply current, there are two possibilities. One is that the target device is damaged or faulty, resulting in a mutation in the internal resistance of the target device, which in turn affects the supply current. The other is that when the target device is operating normally, its own internal resistance will change. For example, the target device is an ignition device on a vehicle.

[0075] In another alternative implementation of this embodiment, the brute-force fan sends a device name request to the target device; the target device sends the device name to the brute-force fan according to the device type request; when the device name is an ignition device, perform step S404.

[0076] Step S403: If so, then disconnect the electrical connection between the brute-force fan and the target device.

[0077] When the target device is in an abnormal operating state, it is necessary to disconnect the electrical connection between the brute-force fan and the target device to protect the brute-force fan and the target device.

[0078] Step S404: If not, then obtain the ambient temperature.

[0079] When the target device is not in an abnormal operating state, and there is a current mutation in the supply current and the current mutation value is within the preset current range, it indicates that the target device is an ignition device on a vehicle.

[0080] Exemplarily, a temperature sensor is provided in the brute-force fan, and the ambient temperature is obtained through the temperature sensor.

[0081] Step S405: In the case where the ambient temperature is less than the first preset temperature threshold, turn on the brute-force fan to make the brute-force fan generate hot air.

[0082] The first preset temperature threshold is a preset temperature value, and the first preset temperature threshold can be adjusted according to the actual situation.

[0083] In the case where the ambient temperature is less than the first preset temperature threshold, it indicates that the ambient temperature is too low and affects the normal operation of the target device. Therefore, in this step, the brute-force fan will be made to generate hot air to increase the temperature of the target device through the hot air.

[0084] In summary, in the case where there is a current mutation in the supply current and the current mutation value is within the preset current range, turn on the brute-force fan and make it generate hot air. This solution can predict and meet the needs of users.

[0085] In the following embodiments, in the embodiments shown in the figure, when the brute-force fan powers the target device, it is necessary to judge under what circumstances the brute-force fan should stop working. Therefore, the embodiment of the present application discloses a schematic flowchart of a control method for a brute-force fan. Refer to Figure 5 , the method includes: Step S501: When it is detected that the supply current remains stable within a preset duration, obtain the current state of the brute-force fan.

[0086] The preset duration is a preset empirical value, and the specific value of the preset duration can be adjusted according to actual needs. For example, the preset duration is set to 5 minutes.

[0087] The current state includes a moving state and a stationary state.

[0088] In some embodiments, a motion sensor is installed inside the brute-force fan, and the current state of the brute-force fan is obtained through the motion sensor.

[0089] Step S502: When the current state is the moving state, continuously turn on the brute-force fan.

[0090] When the current state is the moving state, it means that the user is using the brute-force fan. Therefore, continuously turn on the electric fan for the user to use.

[0091] In some embodiments, the motion trajectory of the brute-force fan is extracted from the current state. When the motion trajectory conforms to the preset motion trajectory, continuously turn on the brute-force fan; when the motion trajectory does not conform to the preset motion trajectory, turn off the brute-force fan. Among them, the preset motion trajectory is the trajectory formed by the brute-force fan making a reciprocating motion, or the trajectory formed by the brute-force fan rotating around an axis.

[0092] Step S503: When the current state is the stationary state, judge whether the brute-force fan is in the held state.

[0093] If the brute-force fan is in the held state, execute step S504; If the brute-force fan is not in the held state, execute step S505.

[0094] When the brute-force fan is in the stationary state, the brute-force fan may be being used or may not be used by the user. Therefore, it is necessary to judge the usage state of the brute-force fan.

[0095] Step S504: If so, continuously turn on the brute-force fan.

[0096] When the brute-force fan is in the held state, it means that the user is still using the brute-force fan. Therefore, continuously turn on the electric fan for the user to use.

[0097] Step S505: If not, turn off the violent fan to stop it from blowing air.

[0098] When the violent fan is not in the held state, it means that the user is not currently using the violent fan. Therefore, turn off the violent fan to stop it from blowing air.

[0099] In summary, according to the current state of the violent fan, determine whether to control the violent fan to continue blowing air, realizing the intelligent operation of the violent fan and reducing the operation steps of the user.

[0100] In the following embodiments, during the process of the violent fan supplying power to the target device, it is also necessary to consider whether the maximum output power of the violent fan itself can match the actual charging power, actual heating power, and actual fan power. For this reason, the embodiments of the present application disclose a flow schematic of a power control method for a violent fan. Figure 1 . Refer to Figure 6 , the method includes: Step S601: When the violent fan is supplying power to the target device and the violent fan is in the air-blowing state, obtain the rated heating power and rated fan power of the violent fan and the rated charging power of the target device.

[0101] Optionally, the violent fan stores the rated heating power and rated fan power.

[0102] Exemplarily, calculate the product of the rated charging voltage and the rated charging current to obtain the rated charging power.

[0103] Step S602: Calculate the sum of the rated heating power, rated fan power, and rated charging power to obtain the target output power of the violent fan.

[0104] The sum of the rated heating power, rated fan power, and rated charging power represents the output power of the violent fan when the violent fan is working normally and the target device is charging normally.

[0105] Step S603: Determine whether the target output power is less than the maximum output power of the violent fan.

[0106] If the target output power is less than the maximum output power of the violent fan, then execute Step S604; If the target output power is less than the maximum output power of the violent fan, then execute Steps S605 to S606.

[0107] Step S604: If so, supply power to the target device according to the rated charging power, and control the violent fan to work according to the rated heating power and rated fan power.

[0108] When the target output power is less than the maximum output power of the brute-force fan, it means that the brute-force fan can provide sufficient output power. While ensuring the normal operation of the brute-force fan, the rated charging power is provided to the target device.

[0109] Step S605: If not, then according to the device type of the target device, the rated charging power is converted to obtain the actual charging power.

[0110] When the target output power is greater than the maximum output power of the brute-force fan, it means that the brute-force fan cannot provide sufficient output power, and the brute-force fan cannot both operate normally by itself and provide the rated charging power to the target device.

[0111] Optionally, when the device type is a non-electricity storage device type, the actual charging power is set to the rated charging power.

[0112] Optionally, when the device type is an electricity storage device type, the actual fan power is set to the rated fan power, and the actual heating power is set to the rated heating power.

[0113] Step S606: According to the maximum output power and the actual charging power, the rated heating power and the rated fan power are updated to obtain the actual heating power and the actual fan power.

[0114] Optionally, calculate the difference between the maximum output power and the actual charging power to obtain the remaining power; allocate the remaining power to obtain the actual heating power and the actual fan power.

[0115] Exemplarily, an electric heating wire is installed inside the brute-force fan, and the actual heating power is generated by the electric heating wire. Further, obtain the first working voltage across the electric heating wire and the first working current passing through the electric heating wire. Calculate the product of the first working voltage and the first working current to obtain the actual heating power.

[0116] Exemplarily, a motor is installed inside the brute-force fan, and the rated fan power is generated by the motor. Further, obtain the second working voltage across the motor and the second working current passing through the motor. Calculate the product of the second working voltage and the second working current to obtain the actual fan power.

[0117] Step S607: Supply power to the target device according to the actual charging power, and control the operation of the brute-force fan according to the actual heating power and the actual fan power.

[0118] Exemplarily, the brute-force fan charges the target device using the actual charging power, and controls the operation of the electric heating wire using the actual heating power and controls the operation of the motor using the actual fan power.

[0119] In summary, according to the rated charging power of the target device, the rated heat generation power of the violent fan itself, and the rated fan power, the power output of the violent fan is allocated so that the violent fan can stably output power.

[0120] In the following embodiments, for the scenario where the target output power is greater than the maximum output power of the violent fan, the violent fan can adjust the power supply strategy of the violent fan according to the remaining power of the target device. The following is a schematic flowchart of a power supply method for a violent fan disclosed in an embodiment of the present application. Figure 2 . Refer to Figure 7 , the method includes: Step S701: When the remaining power of the target device is less than the first preset power threshold, set the actual charging power to the rated charging power.

[0121] The first preset power threshold is a preset empirical value, and the specific value of the first preset power threshold is not limited in the embodiments of the present application. For example, the first preset power threshold is 170% or less of the battery capacity of the target device.

[0122] When the remaining power of the target device is less than the first preset power threshold, the remaining power of the target device is too low. At this time, the main demand of the user is to charge the target device. Therefore, the violent fan gives priority to charging the target device, and the remaining power is allocated to the actual fan power and the actual heat generation power of the power supply device.

[0123] Step S702: Calculate the difference between the maximum output power and the rated charging power to obtain the first remaining output power.

[0124] The first remaining output power is the power used by the violent fan.

[0125] Step S703: Divide the first remaining output power according to a preset ratio to obtain the actual heat generation power and the actual fan power.

[0126] The preset ratio is a preset empirical value, and the specific value of the preset ratio is not limited in the present application.

[0127] Optionally, calculate the heat increase value of the heating wire per unit time according to the actual heat generation power. Calculate the wind speed of the violent fan according to the actual fan power. According to the wind speed and the surface area of the heating wire, calculate the heat loss value of the heating wire per unit time. Control the heat loss value and the heat increase value to be the same.

[0128] Step S704: Control the violent fan to work according to the actual charging power, the actual heat generation power, and the actual fan power.

[0129] Exemplarily, power is supplied to the target device using the actual charging power, the heating wire in the violent fan is controlled to work using the actual heating power, and the motor in the violent fan is controlled to work using the actual fan power.

[0130] Step S705: When the remaining power is greater than the second preset power threshold, set the actual heating power to the rated heating power, and set the actual fan power to the rated fan power.

[0131] The second preset power threshold is a preset empirical value, and the specific value of the second preset power threshold in the embodiments of the present application is not limited. For example, the second preset power threshold is 570% or more of the battery capacity of the target device. Further, the second preset power threshold is less than the power-off power.

[0132] When the remaining power of the target device is greater than the second preset power threshold, the remaining power of the target device has reached a certain amount. At this time, power supply to the target device is no longer the main requirement, so the normal operation of the violent fan itself is preferentially satisfied.

[0133] Step S706: Calculate the difference between the maximum output power and the rated heating power and the rated fan power to obtain the second remaining output power.

[0134] Exemplarily, calculate the sum value of the rated heating power and the rated fan power; calculate the difference between the maximum output power and the aforementioned sum value to obtain the second remaining output power.

[0135] Step S707: Set the actual charging power to the second remaining output power.

[0136] Exemplarily, power is supplied to the target device using the actual charging power.

[0137] In summary, the actual charging power, the actual heating power, and the actual fan power of the violent fan are set according to the remaining power of the target device, so that the violent fan can provide the rated charging power required by the target device, which is beneficial to the charging of the target device.

[0138] In the following embodiments, the violent fan has both power supply and blowing functions at the same time. When the ambient temperature changes, the power of the violent fan also changes. Therefore, the embodiments of the present application disclose a flow schematic of a power supply method for a violent fan Figure 3 . Refer to Figure 8 , this method includes: Step S801: Monitor the ambient temperature.

[0139] Exemplarily, a temperature sensor is installed in the violent fan, and the ambient temperature is monitored through the temperature sensor.

[0140] Step S802: When the ambient temperature is lower than the second preset temperature threshold and the remaining power is greater than the preset power, calculate the average power consumption of the target device per unit time.

[0141] The second preset temperature threshold is a preset empirical value, and the specific value of the second preset temperature in this application is not limited. For example, the second preset temperature threshold is -280 °C.

[0142] Exemplarily, calculate the theoretical power increment of the target device per unit time according to the actual power supply of the violent fan; detect the actual power increment of the target device per unit time; calculate the difference between the theoretical power increment and the actual power increment to obtain the average power consumption.

[0143] Step S803: Adjust the actual charging power according to the average power consumption.

[0144] Adjust the actual charging power to the average power consumption. At this time, the electric energy provided by the violent fan per unit time is the same as the electric energy consumed by the target device per unit time.

[0145] Step S804: Calculate the difference between the maximum output power and the actual charging power to obtain the actual heating power and the actual fan power.

[0146] Exemplarily, divide the difference between the maximum output power and the actual charging power according to a preset ratio to obtain the actual heating power and the actual fan power.

[0147] Furthermore, calculate the heat increment of the heating wire per unit time according to the actual heating power. Calculate the wind speed of the violent fan according to the actual fan power. According to the wind speed and the surface area of the heating wire, calculate the heat loss value of the heating wire per unit time. Control the heat loss value and the heat increment to be the same.

[0148] Step S805: Control the violent fan to work according to the actual charging power, the actual heating power, and the actual fan power.

[0149] Exemplarily, supply power to the target device using the actual charging power, control the heating wire in the violent fan to work using the actual heating power, and control the motor in the violent fan to work using the actual fan power.

[0150] In summary, adjusting the actual charging power according to the ambient temperature and the average power consumption of the target device per unit time enables the power supply device to provide electric energy that meets the average power consumption of the target device, which is beneficial for the power supply device to provide both functions of air supply and power supply simultaneously.

[0151] In the following embodiments, in the actual usage scenario of a brushless fan, the brushless fan is also affected by the environmental humidity, which will affect the user's functional requirements for the brushless fan. The embodiments of this application disclose a flowchart of a power supply method for a brushless fan. Figure 4 . Refer to Figure 9 , the method includes: Step S901: Obtain the environmental humidity.

[0152] Exemplarily, a humidity sensor is installed inside the brushless fan, and the environmental humidity is monitored through the humidity sensor.

[0153] Step S902: When the environmental humidity is greater than the preset environmental humidity, control the brushless fan to work according to the rated heating power and the rated fan power.

[0154] The preset environmental humidity is a preset empirical value, and this application does not limit the specific value of the preset environmental humidity. For example, the preset environmental humidity is 70%.

[0155] When the environmental humidity is greater than the preset environmental humidity, the main demand of the user is to use the power-supplied air outlet function. At this time, the brushless fan takes air outlet as the main function, controls the brushless fan to work according to the rated heating power and the rated fan power, so that the brushless fan can work normally.

[0156] Step S903: When the working duration of the brushless fan reaches the preset working duration threshold, detect the current state of the brushless fan.

[0157] The preset working duration threshold is a preset empirical value, and the embodiments of this application do not limit the preset working duration threshold. For example, the preset working duration threshold is 10 minutes.

[0158] The current state includes a stationary state and a moving state.

[0159] Exemplarily, a motion sensor is installed inside the brushless fan, and the current state of the brushless fan is obtained through the motion sensor.

[0160] Furthermore, when the working duration of the brushless fan reaches the preset working duration threshold, the probability of the user using the brushless fan decreases with time. Therefore, it is necessary to judge whether the user is still using the brushless fan through the current state of the brushless fan.

[0161] Step S904: When the current state is the stationary state, reduce the actual fan power to the target fan power and reduce the actual heating power to the target heating power.

[0162] The target fan power and the target heating power are preset empirical values, and this application does not specifically limit the specific values of the target fan power and the target heating power.

[0163] In summary, according to the environmental humidity, the user's needs are predicted, and when the current state is a stationary state, the actual fan power and the actual heating power are reduced to realize the intelligence of the violent fan.

[0165] In summary, when the violent fan supplies power externally, the power supply voltage and the power supply time are adjusted according to the device type to realize intelligent power supply, ensure power supply safety and power supply speed, and will not cause damage to the target device.
