Such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0039] It should be understood that the specific embodiments described herein are only for explaining the present invention and are not used to limit the present invention. In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without making creative efforts shall fall within the protection scope of this application.

[0040] The present invention provides a reference Figure 1 and Figure 2 , Figure 1 is a module structure diagram of the first embodiment of the rain and snow protection device of the present invention; the rain and snow protection device is arranged opposite to the fan assembly 500; the rain and snow protection device includes a weather detection module 100, a control module 200, a rain and snow blocking cover 300, and an attitude adjustment module 400; the output end of the weather detection module 100 is connected to the input end of the control module 200, the output end of the control module 200 is connected to the control end of the attitude adjustment module 400, and the rain and snow blocking cover 300 is arranged on the attitude adjustment module 400; wherein:

[0041] The control module 200 is configured to obtain the weather data detected by the weather detection module 100, determine the target attitude of the rain and snow blocking cover 300 according to the weather data, generate a control signal corresponding to the target attitude, and send the control signal to the attitude adjustment module 400;

[0042] The attitude adjustment module 400 is configured to adjust the attitude of the rain and snow blocking cover 300 to the target attitude according to the control signal. In the target attitude, the rain and snow blocking cover 300 blocks the rain and snow whose falling direction points to the fan assembly 500.

[0043] The fan assembly 500 includes components related to the fan in the module machine; it can be understood that the rain and snow protection device in this embodiment is to prevent the fan blades 520 from icing or snowing; therefore, the fan assembly 500 may include a second motor 510, fan blades 520, and a flow guide cover 530; the second motor 510 is used to drive the fan blades 520 to rotate, and the flow guide cover 530 is used to set the air outlet direction of the fan blades 520; the specific structure of the fan assembly 500 can be adjusted based on actual needs. At the same time, it can be understood that when the module machine is placed on the ground, the air outlet of the module machine is vertically upward facing the ground. Therefore, the air outlet direction of the fan blades 520 is also vertically upward facing the ground.

[0044] The weather detection module 100 is used to obtain weather data reflecting the real-time weather conditions; the weather detection module 100 can detect the corresponding weather data by setting relevant sensors; it can also obtain the local weather data from the Internet side such as meteorological websites and servers through the networking method. The weather data indicates the real-time weather conditions, and the weather data is composed of different weather parameters, including but not limited to temperature, humidity, wind direction, wind force, whether it is raining, and whether it is snowing.

[0045] The control module 200 is used for data processing; it should be noted that the control module 200 can be a device with data processing capabilities set in the module machine itself, or a device newly added specifically for the rain and snow protection device.

[0046] The rain and snow blocking cover 300 is used to block rain and snow for the fan assembly 500 to prevent rain and snow from falling on the blades of the fan assembly 500.

[0047] The attitude adjustment module 400 is used to adjust the attitude of the rain and snow blocking cover 300; it can be understood that when the weather conditions are different, the falling states of rain and snow are also different. For example, when the wind direction is different, the falling direction of rain and snow is different, and when the wind force is different, the falling angle of rain and snow is different; therefore, in this embodiment, the attitude adjustment module 400 is set to adjust the attitude of the rain and snow blocking cover 300 so that the rain and snow blocking cover 300 can block rain and snow for different weather conditions and prevent rain and snow from falling on the blades of the fan assembly 500.

[0048] Specifically, the corresponding relationship between the specific weather data and the attitude of the rain and snow blocking cover 300 can be determined and stored in advance based on historical data or experiments, that is, in specific weather conditions, the corresponding attitude of the rain and snow blocking cover 300 can block rain and snow and prevent rain and snow from falling on the blades of the fan assembly 500; in the application, after determining the weather data, the target attitude of the rain and snow blocking cover 300 can be matched based on the pre-stored corresponding relationship.

[0049] In this embodiment, the weather detection module 100 is set to determine the falling situation of rain and snow, and the attitude of the rain and snow blocking cover 300 is adjusted based on the falling situation of rain and snow, so that the rain and snow blocking cover 300 can block the rain and snow about to fall on the fan assembly 500, thereby preventing the wind blades 520 in the fan assembly 500 from icing or snowing; at the same time, this method does not completely seal the air outlet of the fan assembly 500, so it can also be used when the fan assembly 500 is running.

[0050] Further, refer to it together later Figure 3, the weather detection module 100 includes a rain and snow detection unit and a wind detection unit; the output end of the rain and snow detection unit is connected to the input end of the control module 200, and the output end of the wind detection unit is connected to the input end of the control module 200; wherein:

[0051] The rain and snow detection unit is used to detect the rain and snow state in the environment and send the rain and snow state to the control module 200;

[0052] The wind detection unit is used to detect the wind state in the environment and send the wind state to the control module 200.

[0053] The rain and snow detection unit is used to detect the rain and snow state; specifically, the data detected by the rain and snow detection unit includes but is not limited to whether it is raining, the rainfall, whether it is snowing, and the snowfall.

[0054] The wind detection unit is used to detect the wind state; specifically, the data detected by the wind detection unit includes but is not limited to the wind direction and the wind speed.

[0055] It can be understood that the purpose of setting the rain and snow protection device is to prevent the wind blades 520 of the fan from icing or snowing; therefore, the rain and snow protection device is only needed in rainy and snowy weather; therefore, in this embodiment, a rain and snow detection unit is set to detect the type of the current environment and determine whether the current environment is rainy and snowy weather; when the current environment is not rainy and snowy weather, the rain and snow protection device is not needed to block rain and snow, while in rainy and snowy weather, the rain and snow protection device is needed to block rain and snow.

[0056] It can be understood that different wind conditions will affect the falling situation of rain and snow; therefore, in this embodiment, a wind detection unit is set to detect the wind condition, so as to determine the falling situation of rain and snow, and then specifically design the rain and snow block based on the falling situation; realize the determination of the target posture of the rain and snow blocking cover 300.

[0057] In this embodiment, by setting the rain and snow detection unit, it can be determined whether rain and snow need to be blocked, and by setting the wind detection unit, the falling situation of rain and snow can be determined, so as to further clarify the target posture of the rain and snow blocking cover 300.

[0058] Further, the wind detection unit includes a wind speed detector; wherein:

[0059] The output end of the wind speed detector is connected to the input end of the control module 200.

[0060] The wind detection unit mainly includes a wind speed and direction detector; the wind speed and direction detector is used to detect the wind direction and wind speed in the current environment; it can be understood that when the wind direction is different, the falling direction of rain and snow is different, and when the wind speed is different, the falling angle of rain and snow is different; therefore, in this embodiment, by setting the wind speed and direction detector, the wind direction and wind speed can be detected, so as to accurately determine the falling situation of rain and snow.

[0061] Further, the attitude adjustment module 400 includes a height adjustment unit and an angle adjustment unit; the rain and snow shielding cover 300 is arranged on the angle adjustment unit, and the angle adjustment unit is arranged on the height adjustment unit; the control end of the height adjustment unit is connected to the output end of the control module 200, and the control end of the angle adjustment unit is connected to the output end of the control module 200.

[0062] In a rain and snow environment, based on different wind conditions, the falling situation of rain and snow is also different; therefore, the requirements for shielding rain and snow are also different.

[0063] Specifically, the wind direction determines the falling direction of rain and snow. Therefore, the inclination direction of the rain and snow shielding cover 300 can be determined based on the wind direction; for example, when the wind direction is southeast wind, the rain and snow fall from the southeast direction to the northwest direction. To shield the rain and snow, it is necessary to control the rain and snow shielding cover 300 to incline towards the southeast direction, that is, the side of the rain and snow shielding cover 300 pointing to the southeast direction sinks, and the side pointing to the northwest direction rises.

[0064] At the same time, the wind speed determines the falling angle of rain and snow; it can be understood that the greater the wind speed, the smaller the angle of the falling path of rain and snow relative to the ground, and the smaller the wind speed, the more perpendicular the falling path of rain and snow is to the ground; therefore, the inclination angle of the rain and snow shielding cover 300 can be determined based on the wind speed; specifically, the greater the wind speed, the smaller the angle of the falling path of rain and snow relative to the ground, and the greater the inclination angle of the rain and snow shielding cover 300; it can be understood that the initial state of the rain and snow shielding cover 300 is parallel to the ground, that is, when it is parallel to the ground, the rain and snow shielding cover 300 is not inclined, and when the rain and snow shielding cover 300 is inclined, an angle is formed between the plane where the rain and snow shielding cover 300 is located and the ground. The greater the inclination angle of the rain and snow shielding cover 300, the greater the angle formed between the plane where it is located and the ground.

[0065] In this embodiment, an angle adjustment unit is set to adjust the inclination direction and inclination angle of the rain and snow shielding cover 300 to meet the needs of different wind conditions.

[0066] Meanwhile, the greater the wind force and the smaller the angle of the falling path of rain and snow relative to the ground, the lower the position from which rain and snow are more likely to fall into the fan assembly 500. Therefore, the lower the shielding height of the rain and snow shield 300 is required; the smaller the wind force, the greater the angle of the falling path of rain and snow relative to the ground, and the higher the position from which rain and snow are more likely to fall into the fan assembly 500. Therefore, the higher the shielding height of the rain and snow shield 300 is required; in this embodiment, a height adjustment unit is provided to adjust the height of the rain and snow shield 300 to meet the needs of different wind forces.

[0067] Further, the height adjustment unit includes a first motor, a gear 411, a gearbox 412, and a slide rail 413; the control end of the first motor serves as the control end of the height adjustment unit, and the first motor and the gear 411 are disposed inside the gearbox 412; wherein:

[0068] The gear 411 is disposed on the output shaft of the first motor, and the gear 411 is meshed with the slide rail 413;

[0069] The slide rail 413 is disposed parallel to the air outlet direction of the fan assembly 500, and the angle adjustment unit is disposed at one end of the slide rail 413 away from the fan assembly 500.

[0070] The first motor is used to be controlled by the control module 200 to drive the gear 411 to rotate; it can be understood that the gear 411 is meshed with the slide rail 413. When the gear 411 rotates, the slide rail 413 moves based on the transmission of the gear 411; at the same time, since the slide rail 413 is disposed parallel to the air outlet direction of the fan assembly 500, when the gear 411 rotates, it will drive the slide rail 413 to move in the air outlet direction of the fan assembly 500; it can be understood that the air outlet direction of the fan assembly 500 is upward, so the slide rail 413 rises or falls based on the rotation of the gear 411.

[0071] The angle adjustment unit is disposed on the slide rail 413, and the rain and snow shield 300 is disposed on the angle adjustment unit. Therefore, when the slide rail 413 moves, it will drive the angle adjustment unit and the rain and snow shield 300 to move together, realizing the control of the height of the rain and snow shield 300.

[0072] The first motor and the gear 411 are disposed inside the gearbox 412, so as to avoid rain and snow from falling on the first motor or the gear 411 and ensure the usability of the height adjustment unit.

[0073] Further, the angle adjustment unit includes a steering ball and a connecting plate; wherein:

[0074] The steering ball is arranged on the height adjustment unit. The steering ball is fixedly connected to the rain and snow shield 300 through the connecting plate, and the control end of the steering ball is connected to the control module 200.

[0075] The steering ball can adjust its own rotation posture.

[0076] The rain and snow shield 300 is fixedly connected to the connecting plate. Therefore, when the steering ball rotates under the control of the control module 200, the rain and snow shield 300 will change its inclination direction and inclination angle following the steering of the steering ball.

[0077] In this embodiment, by setting the steering ball, the control of the inclination direction and inclination angle of the rain and snow shield 300 is realized.

[0078] Further, the rain and snow shield 300 is a sheet metal part made of anti-corrosion material.

[0079] It can be understood that the rain and snow shield 300 needs to block rain and snow and is exposed to the outdoor environment at the same time. Therefore, in order to improve the durability of the rain and snow shield 300, in this embodiment, the rain and snow shield 300 is set to be made of anti-corrosion material; at the same time, the rain and snow shield 300 is supported by the steering ball and the height adjustment unit in sequence. Therefore, in order to improve the durability of the device, the rain and snow shield 300 is manufactured in the form of a sheet metal part, so as to realize the light weight of the rain and snow shield 300, avoid excessive load-bearing pressure on the steering ball and the height adjustment unit caused by the overweight of the rain and snow shield 300, and at the same time, the sheet metal part can also reduce the cost.

[0080] The present utility model also protects a modular machine. Refer to Figure 3 , this modular machine includes a rain and snow protection device, and the structure of this rain and snow protection device can refer to the above embodiment and will not be elaborated here. Naturally, since the modular machine in this embodiment adopts the technical solution of the above rain and snow protection device, this modular machine has all the beneficial effects of the above rain and snow protection device.

[0081] Further, the fan assembly 500 includes a second motor 510, a wind blade 520, and a flow guide cover 530; wherein:

[0082] The wind blade 520 is connected to the output shaft of the second motor 510, the flow guide cover 530 is coaxially arranged with the wind blade 520, and the wind blade 520 is arranged at the air inlet of the flow guide cover 530.

[0083] The second motor 510 is controlled by the control module 200 in the modular machine; when the second motor 510 operates, it drives the wind blade 520 to rotate, and the wind blade 520 rotates to discharge air flow, and the air flow is output to the external environment through the flow guide cover 530. The specific structure of the fan assembly 500 can also be set according to actual needs.

[0084] Further, the rain and snow shield 300 has the same shape as the air outlet of the air deflector 530. The rain and snow shield 300 is coaxially arranged with the air deflector 530, and the diameter of the rain and snow shield 300 is larger than the diameter of the air outlet of the air deflector 530.

[0085] It can be understood that when rain and snow fall, they fall onto the wind blades 520 through the air outlet of the air deflector 530. In this embodiment, the shape of the rain and snow shield 300 is set to be the same as the shape of the air outlet of the air deflector 530, so as to reduce the material used for the rain and snow shield 300 while meeting the shielding requirements. It can be understood that when the shape of the rain and snow shield 300 is not the same as the shape of the air outlet of the air deflector 530, the inconsistent part is not necessary for shielding rain and snow. Therefore, the material of this part increases the cost of the rain and snow shield 300. At the same time, the diameter of the rain and snow shield 300 is set to be larger than the diameter of the air outlet of the air deflector 530, so as to further improve the shielding effect on rain and snow. Specifically, the degree to which the diameter of the rain and snow shield 300 is larger than the diameter of the air outlet of the air deflector 530 can be set based on actual needs.

[0086] It should be noted that in practical applications, the shape of the rain and snow shield 300 can also be set based on the actual shape of the air outlet of the air deflector 530.

[0087] The present utility model provides a control method for a rain and snow prevention device. Refer to Figure 4 , Figure 4 which is a schematic flowchart of the first embodiment of the control method for the rain and snow prevention device of the present utility model. The method includes the following steps:

[0088] Step S10: Receive the weather data obtained by the weather detection module, and determine the target posture of the rain and snow shield according to the weather data;

[0089] The weather detection module is used to obtain weather data reflecting the real-time weather conditions. The weather detection module can detect the corresponding weather data by setting relevant sensors, and can also obtain the local weather data from Internet terminals such as meteorological websites and servers through networking. The weather data indicates the real-time weather conditions, and the weather data is composed of different weather parameters, including but not limited to temperature, humidity, wind direction, wind speed, whether it is raining, and whether it is snowing.

[0090] It can be understood that when the weather conditions are different, the falling states of rain and snow are also different. For example, when the wind direction is different, the falling directions of rain and snow are different, and when the wind speed is different, the falling angles of rain and snow are different. Therefore, in this embodiment, it is necessary to adjust the posture of the rain and snow shield so that the rain and snow shield can shield rain and snow for different weather conditions and prevent rain and snow from falling onto the blades of the fan assembly.

[0091] Step S20, generate a control signal corresponding to the target attitude;

[0092] After the target attitude is determined, a corresponding control signal can be generated; the control signal is used to control the attitude adjustment module; it can be understood that the rain and snow shield is arranged on the attitude adjustment module, so the attitude of the rain and snow shield can be controlled through the attitude adjustment module; specifically, different target attitudes and corresponding control signals can be associated and stored in advance; after the target attitude is determined, the control signal corresponding to the target attitude is determined based on the stored association relationship.

[0093] Step S30, send the control signal to the attitude adjustment module, so that the attitude adjustment module adjusts the attitude of the rain and snow shield to the target attitude, wherein, in the target attitude, the rain and snow shield blocks the rain and snow whose falling direction points to the fan assembly.

[0094] After sending the control signal to the attitude adjustment module, the attitude adjustment module adjusts the attitude of the rain and snow shield to the target attitude based on the control signal; since the target attitude matches the weather data; therefore, in the target attitude, the rain and snow shield can block the rain and snow that will fall into the fan assembly; it can be understood that the rain and snow whose falling direction points to the fan assembly is the rain and snow that will fall into the fan assembly, so in order to prevent the blades in the fan assembly from icing or snowing, this part of the rain and snow needs to be blocked.

[0095] In this embodiment, by setting a weather detection module to determine the falling situation of rain and snow, and adjusting the attitude of the rain and snow shield based on the falling situation of rain and snow, the rain and snow shield can block the rain and snow that is about to fall into the fan assembly, thereby preventing the blades in the fan assembly from icing or snowing; at the same time, this method will not completely seal the air outlet of the fan assembly, so it can also be used when the fan assembly is running.

[0096] Further, see together later Figure 5 In the second embodiment of the control method of the rain and snow prevention device of the present invention proposed based on the first embodiment of the present invention, the step S10 includes the steps:

[0097] Step S11, judge whether the current weather is rain or snow weather according to the weather data;

[0098] Step S12, if the current weather is not rain or snow weather, the target attitude of the rain and snow shield is the highest target height and parallel to the air outlet direction of the fan assembly.

[0099] When the current environment is not rainy or snowy weather, there is no need to block rain or snow. Therefore, it is necessary to ensure the operation effect of the modular machine as much as possible, that is, to avoid the influence of the rain and snow shield on the air outlet of the fan assembly. Therefore, in this embodiment, when the current is not rainy or snowy weather, the target posture of the rain and snow shield is set to be the farthest from the fan assembly and parallel to the air outlet direction of the fan assembly. The farthest distance from the fan assembly means the highest height of the rain and snow shield. The larger the space between the fan assembly and the rain and snow shield, the smaller the influence of the rain and snow shield on the fan assembly. At the same time, the rain and snow shield is set to be parallel to the air outlet direction of the fan assembly. At this time, on the cross-section in the air outlet direction of the fan assembly, the part occupied by the rain and snow shield is only its side thickness part. Therefore, the air flow discharged from the fan assembly will not be blocked by the rain and snow shield, thereby reducing the influence of the rain and snow shield on the fan assembly. At this time, the rain and snow shield is fully opened.

[0100] A detection period can be set. For example, taking 5 minutes as a detection period, at the start of the detection period, it is judged whether the current is rainy or snowy weather, and subsequent operations are performed based on the judgment result.

[0101] It should be noted that since the problem of ice and snow accumulation on the wind blades occurs only in an environment with a relatively low temperature, before judging the rain and snow environment, the ambient temperature where the fan assembly is located can also be detected. When the ambient temperature is less than the preset freezing temperature, then judge whether the current is rainy or snowy weather; and when the ambient temperature is greater than or equal to the preset freezing temperature, it is determined that the current is not rainy or snowy weather.

[0102] In other embodiments, the rain and snow shield can also be moved outside the area of the air flow discharged from the fan assembly, so as to further reduce the influence of the rain and snow shield.

[0103] Further, in the third embodiment of the control method of the rain and snow prevention device of the present invention proposed based on the first embodiment of the present invention, the step S10 includes the steps:

[0104] Step S13 judges whether the current is rainy or snowy weather according to the weather data;

[0105] Step S14 if the current is rainy or snowy weather, then obtain the wind direction and wind speed in the weather data;

[0106] Step S15 determines the target tilt direction of the rain and snow shield according to the wind direction, wherein the target tilt direction is the same as the wind direction;

[0107] Step S16 determines the target height and target tilt angle of the rain and snow shield according to the wind speed;

[0108] Step S17 determines the target attitude corresponding to the target tilt direction, the target height, and the target tilt angle.

[0109] In the case where the current environment is rainy or snowy weather, it is necessary to determine the target attitude of the rain and snow shield based on the specific situation of the rain and snow.

[0110] Specifically, the wind direction determines the falling direction of the rain and snow. Therefore, the tilt direction of the rain and snow shield can be determined based on the wind direction. For example, when the wind direction is southeast wind, the rain and snow fall from the southeast direction to the northwest direction. In order to block the rain and snow, it is necessary to control the rain and snow shield to tilt towards the southeast direction, that is, the side of the rain and snow shield pointing to the southeast direction sinks, and the side pointing to the northwest direction rises. Therefore, the target tilt direction is the same as the wind direction.

[0111] At the same time, the wind speed determines the falling angle of the rain and snow. It can be understood that the greater the wind speed, the smaller the angle of the falling path of the rain and snow relative to the ground, and the smaller the wind speed, the more perpendicular the falling path of the rain and snow is to the ground. Therefore, the tilt angle of the rain and snow shield can be determined based on the wind speed. Specifically, the greater the wind speed, the smaller the angle of the falling path of the rain and snow relative to the ground, and the greater the tilt angle of the rain and snow shield. It can be understood that the initial state of the rain and snow shield is parallel to the ground, that is, when it is parallel to the ground, the rain and snow shield is not tilted. When the rain and snow shield is tilted, an angle is formed between the plane where the rain and snow shield is located and the ground. The greater the tilt angle of the rain and snow shield, the greater the angle formed between the plane where it is located and the ground. Specifically, the tilt angle of the rain and snow shield is 90° - the falling angle of the rain and snow.

[0112] In this embodiment, an angle adjustment unit is provided to adjust the tilt direction and tilt angle of the rain and snow shield to meet the requirements of different wind conditions.

[0113] At the same time, when the wind speed is greater and the angle of the falling path of the rain and snow relative to the ground is smaller, the rain and snow are more likely to fall into the fan assembly from a lower position. Therefore, the shielding height of the rain and snow shield needs to be lower. When the wind speed is smaller and the angle of the falling path of the rain and snow relative to the ground is larger, the rain and snow are more likely to fall into the fan assembly from a higher position. Therefore, the shielding height of the rain and snow shield needs to be higher. In this embodiment, a height adjustment unit is provided to adjust the height of the rain and snow shield to meet the requirements of different wind speeds.

[0114] It should be noted that when it is not rainy or snowy weather currently, the target attitude of the rain and snow shield can also be determined based on the wind direction and wind speed, so as to prevent sundries from falling into the fan assembly.

[0115] Furthermore, the step S16 includes the steps of:

[0116] Step S161, determine the wind force level corresponding to the wind force. Among them, the larger the wind turbine, the higher the corresponding wind force level.

[0117] Step S162, match the target height and the target tilt angle corresponding to the wind force level. Among them, the target height is negatively correlated with the wind force level, and the target tilt angle is positively correlated with the wind force level.

[0118] The wind force level is used to indicate the degree of wind force; the wind force level can be set by using the existing wind speed division method.

[0119] It can be understood that the higher the wind force level, the greater the wind force and the faster the wind speed. In this embodiment, the target height and the target tilt angle are set in the way of dividing levels.

[0120] For example, the wind force level is divided into three intervals: wind force level < 2, 2 ≤ wind force level < 5, wind force level ≥ 5; different wind force level intervals correspond to different target heights and target tilt angles; when the wind force level < 2, the corresponding target height is 1m, and the corresponding target tilt angle is the first angle; when 2 ≤ wind force level < 5, the corresponding target height is 0.8m, and the corresponding target tilt angle is the second angle; when the wind force level ≥ 5, the corresponding target height is 0.5m, and the corresponding target tilt angle is the third angle; among them, the first angle < the second angle < the third angle.

[0121] In practical applications, the corresponding relationship between the wind force and the target tilt angle and the target height can also be set according to actual needs; for example, the corresponding target tilt angle and target height are set for each wind force level; the corresponding target tilt angle and target height are set based on the specific wind speed.

[0122] Furthermore, in the fourth embodiment of the control method of the anti-rain and snow device of the present invention proposed based on the first embodiment of the present invention, the control method of the anti-rain and snow device further includes:

[0123] Step S40, monitor the operating state of the fan assembly and determine whether the fan assembly has stopped operating;

[0124] Step S50, if the fan assembly stops operating, the target posture of the rain and snow shield is the lowest target height and perpendicular to the air outlet direction of the fan assembly.

[0125] When the fan assembly stops running, there is no need for air flow output from the fan assembly. At this time, in order to avoid rain and snow entering the fan assembly to the greatest extent, the target height of the rain and snow shield is set to the lowest. At the same time, the rain and snow shield is perpendicular to the air outlet direction of the fan assembly. Since the shape of the rain and snow shield is the same as that of the air outlet of the flow guide cover and its diameter is larger than that of the air outlet of the flow guide cover, at this time, the rain and snow shield can completely cover the air outlet of the flow guide cover to achieve complete shielding of rain and snow. At this time, the rain and snow shield is completely closed.

[0126] In this embodiment, when the fan assembly stops running, the rain and snow shield completely shields the air outlet of the fan assembly, so as to avoid rain and snow entering the fan assembly to the greatest extent.
