Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0013] In view of this, and to solve the above problems, this application provides a fan. Please refer to it as well. Figures 1-6 , Figure 1 This is a three-dimensional structural diagram of the fan in the first air outlet mode according to one embodiment of this application. Figure 2 for Figure 1 The fan shown is a side view. Figure 3 for Figure 1 The diagram shows a three-dimensional cross-section of the fan.

Figure 6 for Figure 4 The diagram shows a three-dimensional cross-section of the fan.

[0014] This embodiment provides a fan 1, which includes a housing assembly 10. The housing assembly 10 is provided with a first air outlet 200 and a second air outlet 100. The housing assembly 10 is provided with a fan assembly 30, an air outlet regulating assembly 50, and a controller (not shown in the figure). The controller is configured to: detect an abnormal operating state of the fan 1, the abnormal operating state being determined based on at least one of the following states: the housing assembly 10, the first air outlet 200, the second air outlet 100, the fan assembly 30, and the air outlet regulating assembly 50; and in response to the abnormal operating state, execute at least one control action, the control action including at least one of the following: issuing an alarm prompt to the user, disabling the air outlet regulating assembly 50, preventing the start of the air outlet regulating assembly 50, and controlling the air outlet regulating assembly 50 to operate in reverse.

[0015] Fan 1 is a device capable of blowing air outwards. In terms of usage scenarios, the fan 1 provided in this embodiment includes, but is not limited to, household fans and industrial fans. In terms of type, it includes, but is not limited to, table fans and standing fans. This embodiment only illustrates the use of a household table fan. The air blown out by fan 1 can be cold or hot air.

[0016] The fan 1 includes a housing assembly 10, a first air outlet 200, a second air outlet 100, a fan assembly 30, an air outlet adjustment assembly 50, and a controller. The first air outlet 200 and the second air outlet 100 are disposed on the housing assembly 10, while the fan assembly 30, the air outlet adjustment assembly 50, and the controller are all disposed within the housing assembly 10. The housing assembly 10 constitutes the outer shell of the fan 1 and is arranged in a ring shape, forming an overall cylindrical structure. Furthermore, most of the structural components of the fan 1 can be installed inside the housing assembly 10 for effective protection. Optionally, the housing assembly 10 includes a front shell 11 and a rear shell 12. The front shell 11 has an operation panel, and the rear shell 12 has an air inlet 120. Optionally, the fan 1 also includes a base 40, with one end of the housing assembly 10 along its height direction, i.e., the lower end, disposed on the base 40.

[0017] The fan assembly 30 is the core component of the fan 1. The fan assembly 30 includes a fan and a fan drive motor. Driven by the fan drive motor, it generates airflow, which is transmitted through the air guide channel within the housing assembly 10 and finally blown out from the air outlet. Simultaneously, external air enters the housing assembly 10 through the air inlet 120 of the rear housing 12. Optionally, the fan assembly 30 may include, but is not limited to, a centrifugal fan, a cross-flow fan, or an axial flow fan. The fan assembly 30 is disposed within the housing assembly 10 and located at one end of the housing assembly 10, i.e., the lower end. The fan assembly 30 may also be mounted on the base 40 below, and the airflow generated by the fan assembly 30 is blown out towards the other end of the housing assembly 10, i.e., the upper end, allowing airflow from one end of the housing assembly 10 to the other, in other words, airflow from bottom to top.

[0018] In this embodiment, the fan 1 has two air outlets. The air generated by the fan assembly 30 is output from the first air outlet 200 and the second air outlet 100. The first air outlet 200 is located at the top opening of the housing assembly 10 and is arranged in a ring shape so that air blows out from all sides of the fan 1. The second air outlet 100 is located on the side of the housing assembly 10 so that air blows out from one side of the fan 1. Therefore, this embodiment can switch between a ring-shaped air outlet mode and a unidirectional air outlet mode, which can well cope with scenarios of single-person heating and multiple people heating at the same time. Of course, in other embodiments, the first air outlet 200 can be a unidirectional air outlet and the second air outlet 100 can be a ring-shaped air outlet.

[0019] The air outlet adjustment component 50 is used to change the air volume of the first air outlet 200 and the second air outlet 100, thereby realizing the switching of the air outlet mode of the fan 1. The air outlet mode of the fan 1 includes, but is not limited to, the air outlet mode of the first air outlet 200 and the air outlet mode of the second air outlet 100.

[0020] The fan 1 is also equipped with a controller for real-time monitoring and intelligent control of the overall operating status. The controller establishes signal connections with relevant detection elements inside the fan assembly 30, the air outlet adjustment assembly 50, and the housing assembly 10, and can comprehensively determine whether the fan 1 is in an abnormal operating state based on the operating status of each core component of the fan 1. The abnormal operating state can be determined based on the actual state of at least one of the housing assembly 10, the first air outlet 200, the second air outlet 100, the fan assembly 30, and the air outlet adjustment assembly 50.

[0021] When the controller detects any of the above-mentioned abnormal operating states, it will proactively execute corresponding control actions to quickly halt the development of the abnormality and prevent the fault from escalating. Control actions may include at least one of the following: issuing an alarm to the user, disabling the air outlet regulating component 50, preventing the air outlet regulating component 50 from starting, or reversing the operation of the air outlet regulating component 50. Through the above control logic, the controller achieves timely response and safety protection to fan 1 abnormalities, ensuring stable equipment operation and safe use, while also improving user experience and overall machine reliability.

[0022] In summary, this embodiment provides two air outlets on the fan 1: a first air outlet 200 and a second air outlet 100. When the fan 1 is in the first air outlet mode, the air generated by the fan assembly 30 can be blown out from the first air outlet 200 (e.g., ...). Figure 2 (As indicated by the black arrow), at this time, air can be blown out from the first wind deflector 501 above. When the fan 1 is in the second air outlet mode, the air generated by the fan assembly 30 can be blown out from the second air outlet 100 (as shown by the black arrow). Figure 5(As indicated by the black arrow), air can be blown out from the side of the housing assembly 10, enabling air to exit from different positions in different states, increasing the number of air outlet modes, and realizing a dual air outlet mode. This allows for switching between application scenarios and handling airflow situations at varying distances. The first and second air outlet modes of fan 1 are two different states, and the switching between them is controlled by the air outlet adjustment assembly 50. The controller receives user operation commands, controls the air outlet adjustment assembly 50 to perform mode switching, and monitors the working status of each component in real time. When an abnormality is detected, it executes corresponding protective actions to ensure the stable and safe operation of fan 1.

[0023] In some embodiments, the abnormal operating state of the housing assembly 10 is determined based on at least one of the following: the temperature of the housing assembly 10.

[0024] In some embodiments, the fan assembly 30 includes a fan drive motor, and the control action further includes at least one of the following: disabling the fan drive motor, preventing the fan drive motor from starting, and changing the driving force of the drive motor.

[0025] In some embodiments, the temperature of the housing assembly 10 is associated with at least one of the following states: the airflow of the fan drive motor, the first air outlet 200, and / or the second air outlet 100.

[0026] The abnormal operating state of the housing assembly 10 is determined based on its temperature, which is primarily determined by the operating conditions of the fan assembly 30 and the unobstructedness of the air outlet duct. When the fan assembly 30 operates under high load for extended periods, when the air outlet duct is blocked by foreign objects leading to poor heat dissipation, or when internal heat cannot be expelled in time with the airflow, the temperature of the housing assembly 10 will abnormally rise. When the temperature of the housing assembly 10 is too high, on the one hand, it can easily cause thermal deformation and accelerated aging of the housing material, affecting structural strength and service life; on the other hand, users may be at risk of burns when touching the housing, and the high temperature environment may also accelerate the aging of internal electrical components, leading to further risks such as short circuits and malfunctions. Therefore, the controller monitors the temperature of the housing assembly 10 in real time to determine whether it is in an abnormal operating state and executes corresponding control actions when the temperature rises abnormally, ensuring safe use and stable equipment operation.

[0027] After the controller detects that the housing assembly 10 is in an abnormal working state, it performs at least one of the following control actions: issuing an alarm prompt to the user, disabling the air outlet adjustment assembly 50, prohibiting the start of the air outlet adjustment assembly 50, adjusting the air outlet adjustment assembly 50 to reverse operation, disabling the fan drive motor, prohibiting the start of the fan drive motor, and changing the driving force of the drive motor.

[0028] In practice, the controller performs differentiated control actions to address temperature anomalies in the housing component 10 caused by different factors, thereby mitigating the risks in a targeted manner: If the temperature of the housing assembly 10 rises abnormally, it is due to the fan assembly 30 operating under high load for a long time, the motor continuously generating heat, and the heat accumulating inside the housing. The controller can perform the following actions: issue an alarm to inform the user that the fan 1 has been running under overload for a long time; or directly stop the fan drive motor and prevent it from starting, locking the fan operation function to avoid continuous heat generation; or change the driving force of the drive motor, reduce the motor output power and speed, reduce its own heat generation, and gradually reduce the internal temperature of the housing.

[0029] If the temperature of the housing assembly 10 rises abnormally, it is due to obstruction of the air outlet duct by foreign objects or jamming of the air outlet regulating component 50, resulting in abnormal duct closure. This prevents smooth airflow from the fan, hinders internal air circulation, and causes heat dissipation failure, leading to rapid heat accumulation. Such abnormalities can increase the motor load, causing overload and overheating, and can also lead to excessively high housing temperatures, posing risks of burns to users, housing deformation, and damage to internal components. To address such abnormalities, the controller can perform a combination of actions: issue an alarm to indicate duct blockage and poor airflow; simultaneously disable and prevent the start of the air outlet regulating component 50 to avoid exacerbating the blockage; simultaneously reverse the operation of the air outlet regulating component 50 to reset components and clear the airflow duct; and adjust the motor drive force to reduce speed, or directly disable the motor to cut off the heat source. Once the housing temperature returns to normal, the start restriction can be lifted to ensure equipment and operational safety.

[0030] In some embodiments, the fan 1 further includes a heating component, which specifically includes a heating element, and the control action further includes at least one of the following: disabling the heating element or preventing the heating element from being started.

[0031] In some embodiments, when a heating component is provided inside the fan 1, the temperature of the housing component 10 is associated with at least one of the following states: the fan drive motor, the airflow of the first air outlet 200 and / or the second air outlet 100, and the heating element.

[0032] Optionally, the fan 1 also includes a heating component (not shown in the figure). The heating component includes a heating element, which is located on one side of the fan assembly 30. In other words, the heating element is located in the path of the air duct. When the heating element is working, it generates heat, which can increase the temperature of the air and make the blown air warm or hot. In this case, the fan 1 can also be called a heater. When the fan 1 has a built-in heating component, the temperature anomaly monitoring range of the housing assembly 10 is further expanded. The temperature of the housing assembly 10 is related to at least one of the following states: the operating condition of the fan drive motor, the air volume of the first air outlet 200 and / or the second air outlet 100, and the working status of the heating element. The heating element will continuously generate heat when it is working. If the air volume of the fan is insufficient, the air duct is blocked and cannot remove the heat in time, or the heating element works continuously for a long time, the heat generated by the fan will be superimposed, which will quickly raise the temperature of the housing assembly 10, greatly increasing the risk of overheating burns, component aging and damage, and even safety hazards.

[0033] In response to abnormal shell temperature after the heating element is activated, in addition to performing the aforementioned control actions, the controller can also simultaneously disable the heating element and prevent its activation, directly cutting off additional heat sources. In conjunction with the relevant control actions of the fan and air outlet regulating component 50, the shell temperature can be quickly reduced.

[0034] In some embodiments, the abnormal operating state of the first air outlet 200 is determined based on at least one of the following: the air volume and air temperature of the first air outlet 200; the abnormal operating state of the second air outlet 100 is determined based on at least one of the following: the air volume and air temperature of the second air outlet 100.

[0035] The controller uses built-in sensors to collect real-time airflow and temperature data from the first air outlet 200 and the second air outlet 100. It compares the actual measured values ​​with preset values ​​for the corresponding airflow level and heating setting to determine if the air outlet is abnormal. When the actual airflow from the outlet does not match the set airflow level, the actual airflow temperature deviates significantly from the preset temperature corresponding to the heating setting, or a single air outlet has no airflow or experiences sudden temperature fluctuations, the corresponding air outlet is determined to be in an abnormal operating state. Such abnormalities are often caused by factors such as blocked air ducts, failure of the air guide component 60, misalignment of the air outlet adjustment component 50, abnormal operation of the fan drive motor, or malfunction of the heating element.

[0036] In response to abnormal airflow or temperature at the air outlet, the controller shall perform at least one of the following control actions: issue an audible and visual alarm to the user and provide feedback on the abnormal air outlet information; reverse the operation of the air outlet regulating component 50, reset the wind deflector and lifting mechanism 51, and clear the air duct; change the driving force of the fan drive motor to correct the airflow; disable the air outlet regulating component 50 and prevent its start to avoid the abnormality from escalating; disable the fan drive motor and prevent its start; if the fan 1 is equipped with a heating component, simultaneously disable the heating element and prevent its start to prevent abnormally high temperature from causing safety risks. The relevant start restrictions shall be lifted after the airflow and temperature at the air outlet return to normal and the fault is resolved.

[0037] Please see Figures 7-8 The air outlet adjustment assembly 50 includes a first wind deflector 501 and a second wind deflector 502. The first wind deflector 501 is adapted to the first air outlet 200, and the second wind deflector 502 is adapted to the second air outlet 100. The first wind deflector 501 and the second wind deflector 502 are connected and move synchronously up and down in the vertical direction under the drive of the controller to change the air volume of the first air outlet 200 and the second air outlet 100. When the two wind deflectors move upward as a whole, the air volume of the first air outlet 200 and the second air outlet 100 is adjusted. The first wind deflector 501 releases its obstruction of the first air outlet 200, and the second wind deflector 502 obstructs the second air outlet 100, so that air flows out of the first air outlet 200 and not from the second air outlet 100; when the two wind deflectors move down as a whole, the first wind deflector 501 obstructs the first air outlet 200, and the second wind deflector 502 releases its obstruction of the second air outlet 100, so that air flows out of the first air outlet 200 and not from the second air outlet 100.

[0038] The size and shape of the first wind deflector 501 are adapted to the first air outlet 200. The first wind deflector 501 is disposed on the first air outlet 200. By moving vertically up and down, or moving closer to or further away from the first air outlet 200, the airflow volume of the first air outlet 200 is changed. The size and shape of the second wind deflector 502 are adapted to the second air outlet 100. The second wind deflector 502 is disposed within the housing assembly 10. By moving vertically up and down, or changing the obstruction state of the second air outlet 100, the airflow volume of the second air outlet 100 is changed. Furthermore, the first wind deflector 501 and the second wind deflector 502 are connected and move synchronously when moving vertically up and down. By obstructing one air outlet while simultaneously unobstructing the other, the switching between the two airflow modes is achieved.

[0039] In practice, when the two wind deflectors move upward as a whole, the first wind deflector 501 releases its obstruction of the first air outlet 200, and the second wind deflector 502 obstructs the second air outlet 100, thereby allowing air to flow from the first air outlet 200 and preventing air from flowing from the second air outlet 100; when the two wind deflectors move downward as a whole, the first wind deflector 501 obstructs the first air outlet 200, and the second wind deflector 502 releases its obstruction of the second air outlet 100, thereby allowing air to flow from the first air outlet 200 and preventing air from flowing from the second air outlet 100.

[0040] In this embodiment, the vertical movement of the first windbreak 501 and the second windbreak 502 is achieved by the lifting mechanism 51. That is, the fan 1 also includes the lifting mechanism 51. Figures 7-8 The air outlet adjustment assembly 50 further includes a lifting mechanism 51, which is disposed within the housing assembly 10 of the fan 1 and connected to the second windshield 502. The lifting mechanism 51 is configured to drive the two windshields to move up and down along the vertical direction. The lifting mechanism 51 includes a lifting drive part 513, a fixed guide part 511, and a rotating guide part 512. Under the drive of the lifting drive part 513, the rotating guide part 512 can rotate relative to the fixed guide part 511. The fixed guide part 511 extends along the vertical direction. The first slide groove 5113 is provided, and the rotation guide part 512 is provided with a second slide groove 5121 extending in the inclined direction; the second windproof part 502 is provided with a linkage pin 5021, which simultaneously slides and engages with the first slide groove 5113 and the second slide groove 5121; when the rotation guide part 512 is configured to rotate, the linkage pin 5021 is driven to move up and down along the first slide groove 5113 in the vertical direction through the second slide groove 5121, thereby driving the second windproof part 502 and the first windproof part 501 to move up and down.

[0041] The lifting mechanism 51 is disposed inside the housing assembly 10 and above the air outlet mechanism, and is connected to the second air baffle 502. The first air baffle 501 and the second air baffle 502 are connected, and thus connected to the first air baffle 501. The lifting mechanism 51 mainly functions as a lifting mechanism. Therefore, the lifting mechanism 51 can drive the second air baffle 502 and the first air baffle 501 to rise or fall vertically, so that the fan 1 can switch between two air outlet modes.

[0042] In this embodiment, the lifting mechanism 51 includes a lifting drive unit 513, a fixed guide unit 511, and a rotating guide unit 512. The fixed guide unit 511 is normally fixed to other components, thus remaining stationary. The lifting drive unit 513 is rotatably connected to the rotating guide unit 512, providing the rotating guide unit 512 with the power to rotate relative to the fixed guide unit 511. When the lifting drive unit 513 is working, it can drive the rotating guide unit 512 to rotate relative to the fixed guide unit 511.

[0043] Optionally, the inner side of the rotating guide 512 has a gear ring, and the lifting drive 513 includes a drive member and a gear member. The power output shaft of the drive member is connected to the gear member. When the drive member is turned on, it drives the gear member to rotate. The gear member meshes with the gear ring to drive the rotating guide 512 to rotate relative to the fixed guide 511.

[0044] In this embodiment, the transmission method employing gears meshing with a gear ring ensures stable power transmission and precise transmission ratio, preventing slippage and free rotation. This allows for adjustable rotation angle and speed of the rotating guide 512 relative to the fixed guide 511, thereby achieving precise control over the lifting position of the second windshield 502. Simultaneously, the gear ring is positioned inside the rotating guide 512, maximizing internal space and resulting in a more compact overall structure, smaller footprint, and easier assembly of the lifting mechanism 51, thus improving its performance.

[0045] The fixed guide portion 511 is provided with a first slide groove 5113 extending in the vertical direction, and the rotating guide portion 512 has a second slide groove 5121 that is inclined. Understandably, the second slide groove 5121 is inclined so that when the fan 1 is supported on the ground or a table waiting for support, the second slide groove 5121 is inclined relative to the horizontal direction, and / or the second slide groove 5121 is inclined relative to the direction of gravity.

[0046] A linkage pin 5021 is provided on the second windshield 502. One end of the linkage pin 5021 is fixed to the second windshield 502, and the other end is inserted into the first slide groove 5113 of the fixed guide part 511 and the second slide groove 5121 of the rotating guide part 512. When the lifting drive part 513 drives the rotating guide part 512 to rotate relative to the fixed guide part 511, the side wall of the second slide groove 5121 of the rotating guide part 512 applies a thrust to the linkage pin 5021 along the extension direction of the second slide groove 5121, thereby causing one end of the linkage pin 5021 to move relative to the second slide groove 5121 along the extension direction of the second slide groove 5121. The thrust provided by the rotating guide 512 to the linkage pin 5021 can be decomposed into a horizontal component and a vertical component. The horizontal component is canceled or constrained by the first slide groove 5113 of the fixed guide seat, while the vertical component can drive the linkage pin 5021 to move relative to the first slide groove 5113 along its extension direction, so that the linkage pin 5021 descends or rises in the height direction, thereby driving the second windshield 502 and the first windshield 501 to rise and fall smoothly. This embodiment, by setting the cooperation structure of the first slide groove 5113, the second slide groove 5121 and the linkage pin 5021, can efficiently convert the rotational motion of the rotating guide 512 into the linear lifting motion of the second windshield 502, without the need for complex transmission components such as connecting rods and lead screws, making the overall structure simpler and more compact. Meanwhile, through the rotational drive and the guiding cooperation of the first slide groove 5113 and the second slide groove 5121, the lifting movement of the linkage pin 5021 is characterized by uniform force distribution, smooth transmission, and minimal jamming. This ensures stable movement and accurate positioning of the second baffle 502 during its ascent and descent, thereby improving the operational reliability and service life of the lifting mechanism 51. When the lifting mechanism 51 is applied to the fan 1, it can precisely adjust the relative height of the first baffle 501, the second baffle 502, and other components within the fan 1. This allows for smooth switching between different airflow modes, meeting the fan 1's requirements for efficient, stable, and low-noise airflow mode switching and enhancing the performance of the fan 1.

[0047] Understandably, during this process, the second windshield 502 does not rotate relative to the fixed guide 511. By restricting the second windshield 502 to only perform linear lifting and lowering movements and preventing it from rotating circumferentially with the rotating guide 512, rotational deviation, swaying, or jamming of the second windshield 502 during lifting and lowering can be avoided, making the lifting and lowering movement of the second windshield 502 smoother and its positioning more precise. At the same time, it can prevent the second windshield 502 from interfering with or wearing with the surrounding structure, significantly improving the operational stability, reliability, and service life of the lifting mechanism 51, and effectively reducing operating noise.

[0048] In addition, the second wind deflector 502 is connected to the first wind deflector 501. When the fan 1 is in the rising state, the second wind deflector 502 rises and blocks the second air outlet 100. When the fan 1 is in the falling state, the second wind deflector 502 falls and exposes the second air outlet 100.

[0049] In some embodiments, the abnormal operating state of the air outlet adjustment assembly 50 is determined based on at least one of the following states: the lifting drive unit 513.

[0050] In conjunction with the above-described structure of the air outlet regulating component 50, in some embodiments, the abnormal working state of the air outlet regulating component 50 is determined by at least one of the following states: first windshield 501, second windshield, linkage pin, fixed guide 511, rotating guide 512, and lifting drive 513.

[0051] In specific implementation, the abnormal operating states of the air outlet adjustment component 50 are determined by the states of the aforementioned components, including but not limited to internal component failures and abnormal external operating conditions. In one possible example, the abnormal operating states of the air outlet adjustment component 50 include at least one of the following: a heavy object is placed on the first wind deflector 501, causing abnormal up-and-down movement of the lifting mechanism 51; the lifting mechanism 51 is jammed by a foreign object, causing abnormal up-and-down movement of the lifting mechanism 51; the first wind deflector 501 or the second wind deflector 502 is caught in the downward movement of the first wind deflector 501 or the second wind deflector 502. A heavy object is placed on the first wind deflector 501, exceeding the normal load-bearing range of the component, causing the synchronous lifting of the wind deflector to be obstructed and the mode switching to fail; a foreign object enters the first slide groove 5113 of the fixed guide part 511 or the second slide groove 5121 of the rotating guide part 512, obstructing the sliding of the linkage pin, or the rotation path of the rotating guide part 512 is blocked, causing the lifting of the wind deflector to be jammed; during the downward movement of the first wind deflector 501 or the second wind deflector 502, the path comes into contact with the user's limbs, causing sudden clamping resistance and posing a personal safety risk.

[0052] All the above-mentioned abnormalities of the air outlet adjustment components 50 will ultimately be reflected in the changes of the operating parameters of the lifting drive unit 513. The controller can accurately detect abnormalities by collecting core parameters such as the working current, output load torque, actual operating speed, and position feedback signal of the lifting drive unit 513 in real time: if the parameters suddenly change, exceed the standard, stop or have no feedback, the corresponding abnormality can be determined. There is no need to add additional complex detection devices, and the detection logic is simple and reliable.

[0053] In some embodiments, disabling the air outlet adjustment component 50 specifically means: disabling the lifting drive unit 513; prohibiting the start of the air outlet adjustment component 50 specifically means: prohibiting the start of the lifting drive unit 513; and controlling the air outlet adjustment component 50 to rotate in the opposite direction specifically means: changing the driving direction of the lifting drive unit 513 so that the rotation guide unit 512 rotates in the opposite direction.

[0054] Upon detecting any abnormality in any of the aforementioned air outlet adjustment components 50, the controller will respond and execute at least one of the following control actions, providing general adaptability to various abnormalities and specifically mitigating risks: Issue audible and visual alarm prompts to users, clearly indicating the type of abnormality, to facilitate user troubleshooting and handling; Disabling the air outlet adjustment component 50 means directly disabling the lifting drive unit 513, cutting off power output, and preventing abnormal expansion and damage to parts; The start of the air outlet adjustment component 50 is prohibited, that is, the start permission of the lifting drive unit 513 is locked to prevent accidental restart before the abnormality is resolved; Adjusting the air outlet adjustment component 50 to operate in reverse, that is, changing the driving direction of the lifting drive unit 513, causing the rotating guide unit 512 to rotate in the opposite direction, driving the linkage pin and the windshield to move in the opposite direction, thereby realizing jamming release, clamping release, and misalignment reset.

[0055] In response to serious anomalies such as malfunctions of the lifting drive unit 513 itself or failure of transmission coordination, in addition to the above actions, the whole machine protection logic can be used simultaneously to further ensure equipment safety. All control actions are directly executed by the lifting drive unit 513, which is highly compatible with the component structure and has a closed-loop and efficient protection logic.

[0056] Furthermore, before any of the above-mentioned air outlet adjustment components 50 malfunctions are resolved, in order to prevent the malfunction from causing a chain of failures, avoid abnormal increases in the overall load or expansion of safety risks, and at the same time ensure user safety and the lifespan of internal components, the controller will also perform at least one of the following control actions: disable the fan drive motor, prohibit the start of the fan drive motor; when a heating component is provided, the control action also includes at least one of the following: disable the heating element, prohibit the start of the heating element.

[0057] Furthermore, in this embodiment, the fixed guide portion 511 includes a fixed side portion 5111 and a fixed bottom portion 5112 that are bent and connected together. The fixed side portion 5111 is arranged around the outer periphery of the rotating guide portion 512, and the fixed bottom portion 5112 extends inward. The rotating guide portion 512 is supported by the fixed bottom portion 5112. The rotating guide portion 512 includes a rotating member 5122 and a connecting member 5123. The rotating member 5122 is rotatably connected to the fixed guide portion 511, and the connecting member 5123 connects to the side of the rotating member 5122 that is away from the fixed bottom portion 5112. The connecting member 5123 has the second sliding groove 5121.

[0058] In this embodiment, the fixed guide portion 511 includes a fixed side portion 5111 and a fixed bottom portion 5112 that are bent and connected together. The fixed side portion 5111 is arranged around the outer periphery of the rotating guide portion 512, so the fixed side portion 5111 can circumferentially limit and protect the rotating guide portion 512 to prevent the rotating guide portion 512 from radially deviating, shaking, or falling out. At the same time, the rotating guide portion 512 is supported by the fixed bottom portion 5112, which can provide a stable support surface for the rotating guide portion 512, so that the rotating guide portion 512 is subjected to uniform force during rotation. The fixed side portion 5111 and the fixed bottom portion 5112 cooperate with each other to form a ring-shaped support structure, which provides stable axial support and circumferential limitation for the rotating guide portion 512, improves the rotational stability of the rotating guide portion 512 relative to the fixed guide portion 511, and thus improves the operational stability of the lifting mechanism 51.

[0059] In addition, the rotating guide 512 includes a rotating member 5122 and a connecting member 5123. The connecting member 5123 is located on the side of the rotating member 5122 away from the fixed bottom 5112. This allows the mating position of the second slide groove 5121 and the linkage pin 5021 to be far away from the support area of ​​the fixed bottom 5112. As a result, during the movement of the linkage pin 5021 along the second slide groove 5121, interference, friction or jamming between the linkage pin 5021 and the fixed guide 511, the rotating member 5122 or other peripheral structures is effectively avoided, ensuring that the lifting and lowering movement of the second windshield 502 is smoother and more stable.

[0060] In some embodiments, the abnormal working state of the fixed guide portion 511 is determined by at least one of the following: fixed side portion 5111, fixed bottom portion 5112, and first slide groove 5113. In some embodiments, the abnormal working state of the rotating guide portion 512 is determined by at least one of the following: rotating member 5122, connecting member 5123, and second slide groove 5121.

[0061] Please refer to this again. Figure 1In this embodiment, the housing assembly 10 has an operation area 14, and the second air outlet 100 and the operation area 14 are located on the same side of the housing assembly 10.

[0062] An operation area 14 may be provided on one side of the housing assembly 10. An operation panel is provided within the operation area 14, allowing the user to perform various operations, such as turning the machine on and off, controlling the fan 1 to rise and fall, adjusting the airflow, and setting a timer. The operation area 14 typically needs to face the user directly for easy operation. In this embodiment, the second air outlet 100 and the operation area 14 are located on the same side of the housing assembly 10, allowing the air blown from the second air outlet 100 to directly reach the user.

[0063] In some embodiments, the abnormal operating state is further determined based on at least one of the following states: the operation panel. As a core component of human-computer interaction, an abnormality in the operation panel directly affects user operation and the overall stability of the machine, and thus falls within the scope of controller anomaly monitoring.

[0064] Furthermore, the abnormal operating state of the operation panel is determined based on at least one of the following: the internal circuit board of the operation panel. The controller collects and monitors the corresponding electrical signal parameters in real time through the circuit board to determine whether the operation controls and the display screen are in an abnormal state. The core determination logic is as follows: The control panel includes interactive components such as buttons and touch areas. The core issue with its malfunction is the inability or failure of control commands to be transmitted correctly. When the control panel is insensitive or malfunctions, its own trigger resistance and trigger voltage signals are first fed back to the circuit board, and then transmitted from the circuit board to the controller. The key physical parameters collected by the controller are: abnormally high trigger resistance, no normal high / low transitions in trigger voltage, missing or delayed control command signals. Based on these parameters, the control panel is determined to be faulty, specifically manifested as no response to pressing or touching, mis-triggered commands, and ineffective multiple operations.

[0065] Display screen malfunctions include black screen, distorted screen, backlight not working, missing / garbled parameters, and no screen updates. The power supply and communication drive signals of the display screen are first transmitted through the circuit board. The controller collects relevant electrical signals of the screen through the circuit board. When a malfunction occurs, the core parameters are: abnormal power supply voltage of the display screen, interruption of communication data transmission, and low or no display drive current. The controller directly determines the display screen malfunction based on the abnormal signals returned by the circuit board.

[0066] After the controller detects any abnormality on the operation panel, in addition to issuing an alarm, it will simultaneously perform the following protective actions before the abnormality is resolved to avoid machine failure, incorrect airflow mode, or safety risks caused by misoperation: disable the airflow adjustment component 50 and prohibit the start of the airflow adjustment component 50; furthermore, it can also disable the fan drive motor and prohibit the start of the fan drive motor; when the fan 1 is equipped with a heating component, it will simultaneously disable the heating element and prohibit the start of the heating element, thus comprehensively ensuring the safety of the equipment and the user.

[0067] In some embodiments, the fan 1 further includes an anti-tipping component configured to control the on / off state of the fan power supply circuit according to the tilt angle of the fan 1; the abnormal operating state of the anti-tipping component is also determined based on at least one of the following: the tilt angle.

[0068] In some embodiments, the control action further includes at least one of the following: disconnecting the fan power supply circuit or preventing the fan power supply circuit from being turned on.

[0069] The anti-tipping component is used to detect the overall tilt angle of fan 1 and adaptively control the conduction or disconnection of the fan power supply circuit according to the tilt angle, thereby cutting off the power supply to the entire machine in a timely manner when fan 1 tilts or the tilt angle is too large, improving the safety of use. Accordingly, the abnormal working state of fan 1 in this application can also be further determined based on the tilt angle of the fan to achieve more comprehensive safety monitoring. When the tilt angle of the fan exceeds the preset angle range, it is determined that the fan is in an abnormal working state, and corresponding control actions are executed.

[0070] In some embodiments, the anti-tipping component is disposed at the bottom of the fan 1, specifically including a tilt switch and a control circuit. The tilt switch is configured to determine the on / off state of the control circuit according to the tilt angle of the fan 1. The control circuit is connected in series with the fan power supply circuit and is configured to control the on / off state of the fan power supply circuit.

[0071] Furthermore, the anti-tipping component is preferably located at the bottom of the fan 1 or in the base 40 area to more sensitively detect changes in the overall machine's posture. The anti-tipping component specifically includes a tilt switch and a control circuit. The tilt switch is used to sense the real-time tilt posture of the fan 1, while the control circuit is connected in series with the power supply circuit of the fan 1. The tilt switch can control the on / off state of the control circuit according to changes in the tilt angle of the fan 1, further controlling the on / off state of the fan's power supply circuit to achieve tilt protection.

[0072] In some embodiments, when the tilt angle of the fan 1 does not exceed a preset angle range, the tilt switch is in a first state, the control circuit is in a connected state, and the fan power supply circuit is in a connected state; when the tilt angle of the fan 1 exceeds the preset angle range, the tilt switch is in a second state, the control circuit is in a disconnected state, and the fan power supply circuit is in a disconnected state.

[0073] During operation, when fan 1 is placed stably and its tilt angle is within the preset normal range, the tilt switch is in the first state, the control circuit remains conductive, the fan power supply circuit is normally connected, and fan 1 can start and run normally. When fan 1 tilts over or its tilt angle exceeds the preset safety range, the tilt switch switches to the second state, the control circuit is disconnected, and the fan power supply circuit is disconnected, causing fan 1 to stop working and avoiding safety hazards caused by continuous operation.

[0074] In some embodiments, the tilt switch includes a conductive ball and at least one pair of conductive contacts, wherein the first state is that the conductive ball is stationary between the conductive contacts; and the second state is that the conductive ball rolls and changes its contact state with the conductive contacts.

[0075] Optionally, the tilt switch can employ a mechanical triggering structure, specifically including a conductive ball and at least one pair of conductive contacts. When the fan 1 is in a normal posture, the conductive ball remains stationary between the conductive contacts, keeping the tilt switch on, which is the aforementioned first state; when the fan 1 tilts beyond its limit, the conductive ball rolls under the influence of gravity, causing it to contact one of the conductive contacts, changing the contact mode with the conductive contacts, thus changing the on state of the tilt switch, which is the aforementioned second state, thereby achieving reliable detection and triggering of the tilt angle.

[0076] In this embodiment, the anti-tipping component, by setting a tilt switch containing conductive balls and conductive contacts at the bottom of the fan 1 and cooperating with a control circuit connected in series in the power supply circuit, can sense the tilt posture of the fan 1 in real time. When the tilt angle of the fan 1 exceeds the preset range, the conductive balls roll to change the conduction state of the tilt switch, and then the control circuit cuts off the fan power supply circuit to stop the whole machine. This can effectively avoid safety hazards such as electric shock, pinching injury, component damage or fire caused by the fan 1 continuing to run after tipping over, further enriching the safety protection level of the fan 1 and improving the safety and stability of the equipment.

[0077] In some embodiments, the fan 1 further includes a fan power supply circuit, and the abnormal operating state is further determined based on at least one of the following states: the fan power supply circuit; the control action further includes at least one of the following: disconnecting the fan power supply circuit, or preventing the fan power supply circuit from being turned on.

[0078] Furthermore, fan 1 is also equipped with a fan power supply circuit to provide operating power to load components such as the fan assembly 30, the air outlet regulating assembly 50, and the heating assembly. The on / off state of the fan power supply circuit directly determines whether the entire unit can start and operate normally. Accordingly, the criteria for determining abnormal operating states described in this application may further include the operating state of the fan power supply circuit, such as short circuit, open circuit, abnormal current and voltage, abnormal conduction, or inability to conduct, all of which constitute abnormal operating states of the entire unit.

[0079] Correspondingly, the safety control actions performed by the controller are also expanded. When high-risk scenarios such as abnormal fan, abnormal heating, stuck air outlet adjustment component 50, anti-tipping trigger, or abnormal power supply circuit itself are detected, in addition to controlling each component individually, the control actions also include disconnecting the fan power supply circuit and prohibiting the fan power supply circuit from conducting. By directly cutting off the power supply source of the whole machine, the highest level of safety protection is achieved to avoid serious safety accidents such as electric shock, fire, and component burnout caused by abnormal power supply or component failure.

[0080] By incorporating the fan power supply circuit into the status monitoring and control scope, the safety protection system of this fan 1 is upgraded from single component control to whole-machine power supply level safety cut-off, enabling various high-risk anomalies to be quickly stopped by cutting off the total power supply, further improving the thoroughness and reliability of the safety response, and forming a multi-layered and all-round safety protection architecture with component-level control, tilt protection, and abnormal alarm.

[0081] In addition, the fan 1 provided in this application also includes: Please refer again Figure 6 In this embodiment, when the fan 1 is in the lowered state, the first windbreak portion 501 seals against the portion of the other end of the housing assembly 10. The first windbreak portion 501 and the remaining portion of the other end of the housing assembly 10 form a third air outlet 23, from which air can also be blown out. The third air outlet 23 and the second air outlet 100 are located on the same side of the housing assembly 10. Please refer to [reference needed]. Figure 6 and Figure 9 , Figure 9 for Figure 1 This is a partial schematic diagram of the fan from another perspective. In this embodiment, the other end of the housing assembly 10 has a guide slope 13 that faces the first windshield 501 and is inclined upward, so that air is blown out obliquely upward from the third air outlet 23.

[0082] As can be seen from the above, the first windbreak 501 only seals against the other end of the housing assembly 10. The part of the other end of the housing assembly 10 that does not abut against the first windbreak 501 has a surface facing the first windbreak 501, i.e., the upper surface. In this embodiment, this surface can be inclined upward. At this time, this surface can also be called the guide slope 13. When some air is blown out from the third air outlet 23, due to the guiding effect of the inclined guide slope 13, the air can be blown out from the third air outlet 23 at an angle.

[0083] Please refer to this again. Figure 2 In this embodiment, when the fan 1 is in the rising state, the air outlet 200 has two directions: a first direction D1 and a second direction D2. The two directions are opposite, and the first direction is the same as the air outlet 100. The air volume of the first direction is greater than that of the second direction.

[0084] When fan 1 is in the rising state, the second air outlet 100 is blocked, and the first air outlet 200 is open, achieving a ring-shaped airflow. The airflow on the same side as the second air outlet 100 is the first direction, and the airflow on the other side is the second direction. By increasing the airflow in the first direction, the direct blowing effect on the user side can be enhanced, improving heat dissipation or heating efficiency.

[0085] Please refer to the above. Figure 3 , Figure 6 , Figure 10 In this embodiment, the fan 1 further includes an air guide assembly 60, which is disposed within the housing assembly 10 and located on the air outlet side of the air outlet mechanism, and includes an air guide plate 61. The air guide plate 61 is inclined and used to guide the airflow. When the fan is in the descending state, the air guide plate 61 directs the airflow to the second air outlet 100, forming concentrated air supply, reducing internal eddies and resistance, improving air outlet efficiency, and reducing noise. When the fan is in the ascending state, the air guide plate 61 directs the airflow to the annular first air outlet 200, making the circumferential air volume distribution uneven, with the air volume in the first direction being significantly greater than that in the second direction, thereby taking into account both large-area annular air outlet and localized enhanced air outlet, meeting the needs of different usage scenarios. There are multiple air guide plates 61, which are spaced apart along the thickness direction and each is curved in an arc shape, which can evenly distribute and smoothly guide the airflow, further reducing resistance and noise, and improving air outlet stability. In this embodiment, the air volume of the first air outlet 200 and the second air outlet 100 are different when the fan is in the ascending and descending states. Depending on the usage scenario, the air volume of the first air outlet can be set to be greater or less than that of the second air outlet, so as to achieve uniform airflow over a wide area or strong direct airflow in a local area, thereby improving the flexibility of use.

[0086] Please refer to this again. Figure 3 and Figure 9In this embodiment, the first windbreak 501 includes an annular air outlet grille 21, which is disposed at the first air outlet 200. Along the radial direction of the annular air outlet grille 21, the first air outlet 200 includes a first sub-air outlet 201 and a second sub-air outlet 202. The first sub-air outlet 201 is disposed further inward than the second sub-air outlet 202, and the area of ​​the first sub-air outlet 201 is larger than the area of ​​the second sub-air outlet 202.

[0087] The annular air outlet grille 21 is circular, matching the shape of the opening at the other end of the housing assembly 10. The annular air outlet grille 21 has multiple holes arranged in an array, which constitute the aforementioned first air outlet 200. These holes are arranged in a 360° circumferential pattern, allowing air to be blown outwards from the annular air outlet grille 21. Along the radial direction of the annular air outlet grille 21, the first air outlet 200 can be divided into a first sub-air outlet 201 and a second sub-air outlet 202, with the first sub-air outlet 201 positioned further inwards than the second sub-air outlet 202. Along the circumferential direction of the annular air outlet grille 21, the multiple first sub-air outlets 201 located in the inner ring are evenly distributed, and the multiple second sub-air outlets 202 located in the outer ring are evenly distributed. This embodiment allows the area of ​​the first sub-air outlet 201 to be larger than the area of ​​the second sub-air outlet 202. The area of ​​the first sub-air outlet 201 in the inner ring is larger, and the area of ​​the second sub-air outlet 202 in the outer ring is smaller, thereby preventing the user's fingers from being inserted into the fan 1 through the second sub-air outlet 202 in the outer ring.

[0088] The first wind deflector 501 also includes a top cover 22, which is disposed above the annular air outlet grille 21. The surface of the top cover 22 facing the annular air outlet grille 21 is arc-shaped so that the air blown out from the annular air outlet grille 21 is guided by the arc-shaped surface and eventually blows out roughly horizontally, thereby better blowing towards the user.

[0089] Please refer to Figure 11 , Figure 11 for Figure 9 The diagram shows a partial view of the fan after some structural components have been removed. In this embodiment, a one-way air outlet grille 15 is provided at the second air outlet 100 of the housing assembly 10, and the inner wall of the one-way air outlet grille 15 is inclined outward.

[0090] The housing assembly 10 has a second air outlet 100 on its peripheral sidewall. In this embodiment, a one-way air outlet grille 15 may also be provided at the second air outlet 100, and the inner wall of the one-way air outlet grille 15 may be inclined outward, thereby increasing the air outlet area, reducing the air outlet speed, and preventing hot air from impacting the user at too high a speed and causing discomfort. In addition, the outwardly inclined inner wall can optimize the airflow direction and increase the user's heat-receiving area.

[0091] As can be seen from the above, the fan 1 provided in this application embodiment, as a device with multi-mode air outlet function, achieves the dual goals of diversified air supply needs and high safety operation through the coordinated cooperation of various components. Its overall structural design is scientific and reasonable, with clear division of labor and efficient linkage of each component. Combined with the intelligent control of the controller, it forms a complete operation and protection system, which comprehensively improves the practicality, reliability and safety of the device.

[0092] From an overall structural perspective, the housing assembly 10 serves as the mounting and protective carrier for the fan 1, providing a stable installation space for the various internal functional components. Its internal airflow channels guide the orderly transmission of airflow. Outside air enters the housing through the air inlet 120 of the rear housing 12, is processed, and then blown out from the first air outlet 200 and the second air outlet 100, achieving multi-directional and multi-mode air delivery. The base 40 provides stable support for the entire fan 1, ensuring the stability of the equipment during operation and preventing vibrations and other factors from affecting the user experience.

[0093] As the core power component of the fan 1, the fan assembly 30 is the key to generating airflow. It includes a fan and a fan drive motor. Driven by the fan drive motor, the fan can stably generate airflow and provide sufficient power for the air outlet. Different types of fans, such as centrifugal fans, cross-flow fans, and axial fans, can be selected to adapt to different air outlet needs and scenarios. The fan assembly 30 is installed on the base 40 at the lower end of the housing assembly 10. The generated airflow is transmitted from bottom to top in the air guide channel, and finally achieves effective air delivery.

[0094] The air outlet adjustment component 50 is the core component for achieving multi-mode air outlet switching. Through the cooperation of structures such as the lifting drive unit 513, the lifting mechanism 51, the rotation guide unit 512, the first wind deflector 501, and the second wind deflector 502, it can flexibly change the air volume distribution of the first air outlet 200 and the second air outlet 100, thereby realizing the switching of different air outlet modes and meeting the user's air supply needs in different scenarios. Among them, the lifting drive unit 513 serves as the power source for the air outlet adjustment component 50, and its operating state directly determines the stability and accuracy of air outlet adjustment. Driven by the lifting drive unit 513, the lifting mechanism 51 moves the wind deflector up and down. By adjusting the position of the wind deflector, the air outlet channel can be switched and the air volume can be adjusted.

[0095] The heating component, as an optional functional component, includes a heating element that can heat the blown air when needed, enabling the fan 1 to have a warm air function, further expanding the application scenarios of the device, especially suitable for use in low-temperature environments, and improving user comfort.

[0096] The anti-tipping component is located at the bottom of fan 1 or in area 40 of the base. It includes a tilt switch and a control circuit. The tilt switch has a built-in conductive ball and conductive contacts, which can switch the on / off state according to the tilt posture of fan 1. The control circuit is connected in series with the fan's power supply circuit to control the power supply circuit's on / off state based on the tilt switch's state. When fan 1 is placed stably and the tilt angle is within a preset range, the tilt switch remains on, and the power supply circuit is normally connected. When fan 1 tilts or falls beyond its limit, the conductive ball rolls, triggering the tilt switch to activate. The control circuit then immediately cuts off the power supply circuit, causing fan 1 to stop immediately. This prevents the fan from continuing to run after tipping over, thus avoiding safety hazards such as electric shock, component damage, fire, or personal injury. It complements the overall machine's safety control logic, providing complementary protection.

[0097] The fan power supply circuit, as an independent power supply management module, is used to connect to an external power source and stably supply operating power to all electrical components such as the fan assembly 30, air outlet regulating assembly 50, heating assembly, and controller. It serves as the power source for the entire unit and possesses independent on / off and fault monitoring attributes. The abnormal operating states of this module cover various scenarios, including internal short circuits, open circuits, abnormal conduction, inability to conduct, unstable power supply voltage, and external power supply failure or abnormal input power. These are all incorporated into the overall unit safety monitoring system as independent anomaly detection dimensions. Its operating state is independent of other functional components and directly determines whether the entire unit can be powered and operated normally.

[0098] As the core of fan 1, the controller is responsible for status monitoring, anomaly identification, and safety handling, and is crucial to ensuring the safe and stable operation of fan 1. The controller establishes signal connections with the housing assembly 10, the first air outlet 200, the second air outlet 100, the fan assembly 30, the air outlet adjustment assembly 50, the heating assembly, the anti-tipping assembly, and the fan power supply circuit, respectively, to achieve full-process monitoring and intelligent control of the entire machine's operating status. On one hand, the controller collects real-time operating status information from the housing assembly 10, the first air outlet 200, the second air outlet 100, the fan assembly 30, the air outlet adjustment assembly 50, the heating assembly, the anti-tipping assembly, and the fan power supply circuit. Abnormal operating states of the fan assembly 30 can be determined based on feedback signals such as the current, speed, and start / stop status of the fan drive motor. Abnormal operating states of the air outlet adjustment assembly 50 are determined based on parameters such as the operating current, load torque, position signal, operating speed, or stall signal of the lifting drive unit 513, including situations where the first baffle 501 is carrying heavy objects causing the lifting... The abnormalities of the lifting mechanism 51 include overload, obstruction by foreign objects, and contact with the user during the downward movement of the windshield. Abnormalities in the housing assembly 10 can be determined based on the housing temperature. Abnormalities in the first air outlet 200 and the second air outlet 100 can be determined based on the corresponding airflow and temperature. Abnormalities in the heating assembly can be determined based on the working status of the heating element. Abnormalities in the anti-tipping assembly are determined based on parameters such as the operation status and conductivity reliability of the tilt switch. Abnormalities in the fan power supply circuit are determined based on fault states such as short circuit, open circuit, abnormal conduction, and unstable power supply. Each type of abnormality corresponds to a detectable characteristic feedback signal to ensure accurate and reliable abnormality identification. Furthermore, when the controller detects any of the above abnormal working states, it executes corresponding control actions individually or in combination, depending on the abnormality type and safety level. In response to the abnormality of the air outlet regulating component 50, the lifting drive unit 513 should be controlled first. Since the air outlet regulating component 50 directly controls the air outlet distribution and air outlet mode switching, its abnormality can easily cause air duct blockage, motion interference or abnormal fan load. Therefore, by disabling the lifting drive unit 513, prohibiting the starting of the lifting drive unit 513, or changing the driving direction of the lifting drive unit 513 to make the rotation guide unit 512 rotate in the opposite direction, the abnormality can be quickly resolved and the risk can be avoided from expanding.In response to malfunctions in the housing assembly 10, the first air outlet 200, or the second air outlet 100, the controller can adaptively adjust the driving force of the fan drive motor, or execute actions to disable or prohibit the start of the fan drive motor. For malfunctions in the fan assembly 30, the controller can disable or prohibit the start of the fan drive motor. For malfunctions in the heating assembly, the controller can disable or prohibit the start of the heating element. In cases where the anti-tipping assembly is triggered or malfunctions, the controller can perform protective actions such as power-off locking and alarm prompts. For high-risk malfunctions such as fan power supply circuit failures or hand-clamping or heating abnormalities, the controller adds source-level control actions to disconnect or prevent the fan power supply circuit from conducting, directly cutting off the power supply to the entire unit and completely avoiding major safety risks. The above control actions for different components can be implemented individually or in combination simultaneously depending on the actual malfunction, and alarm prompts will be issued to the user simultaneously for timely troubleshooting and handling.

[0099] In response to the possibility of multiple concurrent anomalies during actual operation, the controller adopts a priority control strategy. It prioritizes handling anomalies with higher safety risk levels and greater harm to the whole machine (such as hand pinching, jamming, heating element abnormalities, fan power supply circuit failures, and other high-risk, high-hazard anomalies), while also taking into account other anomalies. It can execute multiple control actions simultaneously to achieve linkage protection under multiple anomaly scenarios and avoid the superposition and expansion of faults.

[0100] In summary, this fan 1, through the coordinated structure of the housing assembly 10, fan assembly 30, air outlet adjustment assembly 50, base 40, heating assembly (optional), anti-tipping assembly, and fan power supply circuit, achieves diverse functions such as multi-mode air outlet, warm air supply, and automatic safety control, meeting the usage needs of different users and different scenarios. The controller's intelligent management system, through precise anomaly identification, adaptive emergency response, and priority handling of multiple concurrent anomalies, effectively solves the problems of single-mode safety management, insufficient hierarchy, and lack of closed-loop management in existing equipment. It comprehensively avoids damage, escalation of faults, and personal safety hazards caused by abnormal component operation, significantly improving the stability, reliability, and safety of fan 1 operation, extending the overall service life of the machine, and reducing user maintenance costs, providing users with a safe, convenient, and comfortable user experience.
