Description

Technical Field

[0001] The present invention relates to a sudden air supply and pest repelling device and a working method thereof, more specifically, to a device and a working method thereof that can simulate sudden fan action, sudden reversal, and sudden physical action as needed, and provide a high-quality experience and practical effect for heat-relieving and cooling for human and animal husbandry, repelling mosquitoes, and physical pest repelling in planting and vegetation protection applications, thereby avoiding the "electric fan disease (air-conditioning disease)" caused by existing electric fans for human use, replacing chemical (drug) pest repelling with an effective physical pest repelling method, and avoiding the serious harm caused by chemical (drug) pest repelling in the world. Background Art

[0002] Fanning has been an important way for humans to dispel heat and cool down, and to repel mosquitoes since ancient times. Vibrations such as tail flicking and wings are effective ways for humans and poultry and livestock to repel mosquitoes themselves, and to repel moth pests, birds, mice and other harmful animals in growing areas. Despite thousands of years of technological development, the fan has been passed down to this day and has never disappeared, which shows that it is highly practical and effective.

[0003] Technological advances in mechanization are often driven by the desire to replace high-intensity or tedious continuous physical activity. This motive led humanity to invent electric fans driven by rotating motors to replace the manual fanning motion. Traditional fans are also used in breeding and animal husbandry. However, as we all know, continuous, stable airflow creates a poor user experience for humans and animals, and can cause "fan illnesses" such as chills and colds. To address this, electric fan technology has been improved mechanically to include a swaying fan head (shaking head) or a swinging wind direction (swinging wind) structure, and control technology to include a so-called natural wind method with variable speed (gusts). These improvements aim to break the stable, continuous air supply model and pursue variability in air supply to improve the user experience.

[0004] While chemical (drug) and physical pest control methods are used in operations such as animal husbandry, animal husbandry, cropping, and vegetation pest control, chemical (drug) pest control has become a globally recognized public nuisance, and its side effects are well known. Current physical pest control technologies are still limited to sound repelling (playing or creating sounds believed to frighten pests), motion repelling (similar to traditional scarecrows, or causing objects like scarecrows to sway or rotate), and industrial fans (limited to small, enclosed areas such as breeding sheds and greenhouses). These methods, due to their strong regularity, can repel pests for a few minutes or at most a few hours, but soon after the regularity recurs, pests identify them as "natural phenomena" and ignore them. It is precisely the failure of physical pest control technologies that has made chemical (drug) pest control a last resort for the crop industry.

[0005] On the other hand, traditional fans may encounter unexpected obstacles and debris at any time during operations such as breeding, animal husbandry, pest control in planting areas, and vegetation pest control due to livestock activities, natural forces (wind and rain, etc.), etc., causing resistance to the shaking mechanism and causing motor stalling and other faults.

[0006] Research and personal experience collected from numerous volunteers revealed that, compared with the services provided by numerous electric fans (including swing-type air conditioners) with shaking head and gust functions, and the services provided by hand-cranked fans, the experience provided by hand-cranked fans is still the first choice; and through experiments on applying physical disturbances to mosquitoes, moths, mice, and sparrows (experience animals), it was found that continuous, unchanging, and regularly changing wind disturbances have a disturbing effect on the experiencing animals within 5 to 13 minutes, after which the experiencing animals develop an instinctive adaptability; continuous, unchanging (such as constant voltage and frequency, high frequency modulated by low frequency) and regularly changing (such as looping recordings) sound disturbances have a disturbing effect on the experiencing animals within 1 to 3 minutes, after which the experiencing animals develop an instinctive adaptability; and traditional fanning, sudden slapping sounds, flapping sounds, sound effects simulating the attack of natural enemies, and flashing lights and shadows, etc., are still the preferred options for disturbing the experiencing animals.

[0007] The research concluded that traditional hand-cranked fans remain relevant for cooling down and repelling mosquitoes. Meanwhile, traditional fanning, sudden slapping and flapping sounds, and simulated predator attack sound effects and light and shadow flashes are also preferred for pest control in aquaculture, animal husbandry, crop cultivation, and vegetation protection. Research on the commonalities between these two needs revealed that intermittent, sudden, simulated flashes, and simulated sounds are crucial for meeting both requirements.

[0008] In the current electric fan (including air conditioning) technology, due to the characteristics of fan-type loads and the inertia of the rotation of the fan blades, it is difficult for the wind wheel itself to achieve "sudden" movement; and the current head swing and wind swing technologies are: through the mechanical structure to drive the wind wheel to rotate as a whole to achieve head swing, or set a wind guide plate driven by the mechanical structure in the wind path to achieve wind swing; because the mechanical structure that drives the wind wheel or the wind guide plate itself is driven by an independent motor + reduction mechanism, or driven by the fan main shaft through a reduction mechanism, or driven by the wind force generated by the wind wheel, it can only achieve periodic movement, and is destined to be difficult to achieve "sudden" movement. Even if sudden head swing is achieved, the large inertia of the wind wheel will cause large vibration, which requires extremely high strength and shock resistance of the mechanical structure. At present, no related technology has appeared.

[0009] Based on the above research, sudden movement air supply is the key to cooling down and repelling mosquitoes for high-experience people; sudden physical occurrence is also the key to physical pest control in planting and vegetation protection applications, and it is worth investing in it. Summary of the Invention

[0010] The present invention aims at the problems of "electric fan disease (air-conditioning disease)" and poor user experience caused by current electric fans for people, and the hazards of chemical (drug) pest control in aquaculture, animal husbandry, planting and vegetation protection applications, and the ineffectiveness of physical pest control. The present invention combines the analysis of background technology, and the experience survey of electric fans for people and animals and hand-cranked fans, the effect test of physical pest control in existing aquaculture, animal husbandry, planting and vegetation protection applications, and the comparative test of physical pest control methods such as fanning, sudden slapping sounds, flapping sounds, and sound and light effects simulating the attack of natural enemies, to obtain intermittent and sudden fan technology for people and animals, which plays a key role in the needs of cooling down the heat, repelling mosquitoes, and pest control needs in aquaculture, animal husbandry, planting and vegetation protection applications. Furthermore, a sudden air supply and pest control device and a working method thereof are provided.

[0011] To achieve the above objectives, the present invention provides the following technical solutions:

[0012] A sudden air supply and harm repellent device (hereinafter referred to as "the device of the present application") and a working method thereof (hereinafter referred to as "the method of the present application"), wherein:

[0013] 1) Apparatus of the present application: The apparatus of the present application is provided with a plurality of independently driven wind rotors fixed together. Wind direction is changed by the difference in the propulsive torque exerted by each wind rotor on the air. The speed of wind direction change is controlled by controlling the magnitude of the difference in the propulsive torque exerted by each wind rotor on the air. The apparatus of the present application includes a working head, a support shaft, a rotary power transmission device, a control circuit board, a base, and necessary human-machine interface devices.

[0014] The working head includes at least two wind wheel assemblies and a rigid bracket. Each wind wheel assembly is composed of a wind wheel, a shield and its drive motor. Each wind wheel assembly is fixed to the bracket. The drive motor of each wind wheel is electrically connected to the control circuit board.

[0015] The support shaft includes an axis and a bearing, wherein the axis is fixed to the base and the bearing is fixed to the bracket, or vice versa;

[0016] The rotary electric power transmitter comprises a slip ring and a brush, wherein the brush is elastic and in close contact with the slip ring to achieve a movable electrical connection between the two; the brush is fixed to the bracket, and the slip ring is fixed to the axis, or vice versa;

[0017] The control circuit board includes an energy storage element, a motor drive circuit, a central processing unit, and necessary power management circuits, and is electrically connected to the human-computer interaction device; the motor drive circuit corresponds to the wind wheel one by one and is electrically connected to achieve independent driving of each wind wheel.

[0018] 2) The method of the present application includes the following steps in no particular order and which may be arranged and combined with each other:

[0019] S1. Balanced Drive: The central processing unit provides balanced electrical signals to the drive circuits of each impeller drive motor, balancing the driving torque of each impeller on the air, thereby keeping the working head stationary relative to the base or driving the working head to rotate at a constant speed along the support shaft;

[0020] S2. Micro-differential drive: The central processing unit provides short-term or micro-differential unbalanced electrical signals to the drive circuits of each wind rotor drive motor, causing a short-term or micro-differential difference in the driving torque of each wind rotor on the air, thereby causing the working head to generate a short-term or micro-differential acceleration along the support shaft;

[0021] S3. Large differential drive: The central processing unit provides a braking signal or a reverse driving signal to at least one wind wheel drive motor, so that the driving torque of each wind wheel on the air produces a large difference, thereby driving the working head to rotate rapidly along the support shaft.

[0022] This technical solution breaks through the hard-driving idea of ​​the shaking head and swinging air mechanism in the traditional air supply device (the shaking head and swinging air mechanism are driven by the air supply main shaft after being decelerated by the reducer, or the shaking head and swinging air mechanism are driven by the additional electric motor after being decelerated by the transmission mechanism), and breaks through the driving idea of ​​the swinging air mechanism in the traditional air supply device that the wind outlet of the air supply device blows the passive impeller to move it and thus constrain the wind direction. It utilizes multiple separately driven wind wheels fixed to the same working head, and applies unbalanced drive to different wind wheels, so that the working head is subjected to unbalanced force, thereby causing the working head to rotate along the support shaft to complete the change of air supply direction.

[0023] 1) Since the device of the present application does not involve a special shaking head or swinging air mechanism, it is not subject to the trajectory, stroke, etc. of the traditional shaking head or swinging air mechanism, and does not need to work periodically in synchronization with the air supply main shaft, making the wind direction change of the device of the application more "irregular", that is, it has the flexibility of sudden air supply and sudden change of direction of air supply.

[0024] 2) The wind direction change of the device of the present application relies on the torque difference of the reaction force of each wind wheel on the air. It is a soft drive and will not cause the main shaft motor or the shaking motor to get stuck or malfunction due to obstacles or resistance encountered during the wind direction change process, thereby eliminating the mechanical (rigid) and rigidity of traditional designs in application.

[0025] 3) Compared with the traditional design, in the traditional design, the wind speed regulation is limited by the rotational inertia of the wind wheel and the response speed is slow, and the head shaking and swinging wind regulation is limited by the response speed of the driving mechanism, and cannot realize the rapid change of wind speed + wind direction to simulate the effects of sudden fanning and flapping. In the device of the present application, multiple independently driven wind wheels are used, and the rotational inertia of each wind wheel is balanced with each other around the support shaft. The power for the head shaking and swinging wind regulation comes from the torque difference applied by each wind wheel to the support shaft. The tiny torque difference can drive the working head to move, and can realize head shaking and swinging wind in a wide speed range, providing the possibility for rapid rotation to simulate the effects of sudden fanning and flapping. The rapid rotation of the working head can utilize the difference between the main wind and the side wind to realize rapid change of wind speed - that is, the device of the present application can bypass the rotational inertia limitation of the wind wheel and realize rapid response of wind speed and wind direction.

[0026] As a preferred technical solution, the multiple wind wheels of the device of the present application have different sizes and the powers of their driving motors. The wind wheels with larger sizes and larger powers of their driving motors are working wheels, and the rest are regulating wheels. Moreover, within all speed ranges of the working wheels, the regulating wheels have working points that balance the driving torques of the wind wheels on the air.

[0027] This technical solution uses a large, high-power wind wheel as the working wheel, and a small, low-power wind wheel as the regulating wheel. The device in this application adjusts the resultant torque received by the working head by controlling the speed and direction of the regulating wheel, causing it to rotate or stop as required. Because the regulating wheel is small and has low power, it has low inertia and a fast response speed during speed and direction adjustment, allowing the working head to turn faster and meet sudden air supply requirements.

[0028] As a further preferred technical solution, the central axes of the wind rotors of the device of the present application are parallel, and the distances from the centers of the wind rotors to the support shaft are different; or

[0029] The central axes of the working wheel and the regulating wheel are not parallel to each other, so as to reduce the size of the working head.

[0030] When the central axes of the wind wheels are parallel, due to the different sizes and powers of the wind wheels, in order to achieve balance, the lengths of the force arms of the wind wheels need to be different. Therefore, in this solution, the adjusting wheel needs to have a longer force arm to balance the torque of the working wheel. The overall structure is simple and the torque calculation is simple, but the size of the working head is slightly larger.

[0031] When the central axes of the wind rotors are not parallel, this solution preferably positions the central axis of the regulating wheel perpendicular to the support axis, while the central axis of the impeller is not perpendicular to the support axis. This reduces the effective torque between the impeller and the support axis, requiring a shorter lever arm for the regulating wheel to balance the torque of the impeller, thus reducing the overall size of the work head.

[0032] As a further preferred technical solution, the drive circuit for the regulating wheel is a bridge circuit, capable of implementing forward and reverse drive and dynamic braking on the regulating wheel. Specifically, the central processing unit can adjust the control signal to the drive circuit of the regulating wheel, causing the drive circuit to drive the regulating wheel to achieve adjustable forward rotation, adjustable reverse rotation, dynamic braking, reverse braking, and other functions, thereby diversifying the operating modes of the working head. Crucially, by implementing dynamic braking, reverse braking, and reverse rotation of the regulating wheel, rapid rotation of the working head can be achieved, i.e., sudden air supply, simulating the effects of traditional rapid fanning and flapping.

[0033] As a further preferred technical solution, the working head is further provided with: (1) an acoustic wave generator, correspondingly provided with an acoustic wave drive circuit on the control circuit board; and / or (2) a light generator, correspondingly provided with an optical drive circuit on the control circuit board. The emission directions of the acoustic wave generator and light generator are coordinated with the air supply direction of the working head.

[0034] In this technical solution, the "emission direction of the sound wave generator and the light generator is coordinated with the air supply direction of the working head (hereinafter referred to as "emission coordination")", including but not limited to the emission directions being consistent or parallel or slightly angled, the emission paths being consistent or parallel or slightly angled, etc.

[0035] Sound waves, including frequencies within the hearing range of harmful animals, and ultrasonic waves.

[0036] The addition of the sound wave generator can add the function of driving away harmful animals such as birds and mice that have hearing by making threatening sounds and / or simulating the scene of natural enemies attacking (sound of rapid approach).

[0037] The addition of a light generator can add the function of scaring away insects, butterflies, moths, birds and mice that have vision by scaring away insects and butterflies and moths and driving away harmful animals such as birds and mice.

[0038] Combined with the launch coordination technology, the comprehensive effect of sound and wind, and / or the comprehensive effect of light and wind can be achieved, better simulating the scene of attack from heaven and earth and providing better harm-repelling effect.

[0039] As a further preferred technical solution, the device of the present application is also provided with a position sensing device, which includes but is not limited to a travel switch, and / or a rotary rheostat, and / or an encoder; the position sensing device includes a movable part and a fixed part, which are respectively linked to the axis and bearing of the support shaft.

[0040] After setting the position sensor, the central controller can obtain the current relative angle of the working head relative to the base through the status and data of the position sensor, and can also sense the current rotation direction and rotation speed of the working head relative to the base through the status of the position sensor, data changes and change speed. Therefore, by adjusting the signal of the control circuit of each wind wheel, the rotation direction, speed and position of the working head can be closed-loop and accurately controlled to further accurately achieve various expected swinging effects. In particular, ① in the application of heat-relieving air supply for humans and breeding, the swing range of the working head can be set according to the actual space needs, avoiding the drawbacks of the traditional shaking head fan technology that the swing range is fixed and cannot be changed; ② It can realize directional or time-sharing scanning in a certain direction or a certain range of sudden air supply and pest control actions, which is conducive to realizing sudden attacks in a certain direction or a certain range without dead angles, better simulating actions such as sudden fanning and flapping, and having better pest control effects.

[0041] As a further preferred technical solution, the position sensing device of the device of the present application includes a circular baffle, a pair of photoelectric switches, and a necessary light shield (for shielding interference from ambient light); a plurality of slots are provided on the circular periphery of the circular baffle; the photoelectric switch includes a light-emitting element, a photosensitive element and its supporting circuit, which are respectively arranged on both sides of the circular baffle, corresponding to the slot positions on the circular baffle; the circular baffle and the photoelectric switch are respectively linked to the axis and bearing of the support shaft.

[0042] This solution preferably uses a photoelectric position sensor, including but not limited to: ① multiple photoelectric switches are arranged in a fixed position + a single slot on the circular baffle to detect multiple angular positions of the working head; ② photoelectric switches + multiple slots evenly arranged on the circular baffle to detect the direction and speed of the working head (i.e., drawing on the incremental photoelectric encoder technology); ③ on the basis of ②, a mark photoelectric switch is added at a radius deviating from the location of the photoelectric switch in ②, and correspondingly, a mark slot is added on the circular baffle of ② at the radius corresponding to the mark photoelectric switch, so that each time the working head rotates to the mark photoelectric switch and is triggered by the mark slot, the position sensor is calibrated once, and the operation effect of the absolute photoelectric encoder can be obtained, and accurate detection of the working head position, speed, and direction can be achieved, thereby achieving a better air supply range and its harm repelling effect.

[0043] As a further preferred technical solution, a mechanical limiter is provided on the base of the device of the present application to limit the reciprocating swing range of the working head.

[0044] In traditional fan oscillating structures, the following technical solutions are often used: ① The main shaft of the wind wheel is decelerated by a reduction gear and then drives the mechanical oscillating mechanism; ② The independent motor is decelerated and then drives the mechanical oscillating mechanism. The traditional fan oscillating structure has a fixed oscillating stroke. When encountering resistance during the oscillating stroke, it can only try to forcibly break through the resistance to continue to complete the unfinished stroke. Once the resistance cannot be broken through, it will be stuck in the current position and cannot continue to oscillate. It may even cause overcurrent and damage to the motor due to obstruction. In this solution, since the rotation of the working head is driven by the torque difference generated by the thrust of multiple wind wheels on the air, it is a soft drive. Even if resistance is encountered during the oscillating stroke, it will not cause overcurrent or damage to the motor or the oscillating structure, and no abnormal noise will occur. A mechanical limiter is provided on the base, that is, an obstacle is provided in the oscillating stroke of the working head, which can limit the reciprocating swing range of the working head and make it oscillate back and forth within the range set by the mechanical limiter.

[0045] As a further preferred technical solution, the mechanical limiter of the device of the present application is detachable, and a sliding groove or multiple slots are provided corresponding to the mechanical limiter.

[0046] This solution provides users with technology that allows them to freely adjust the range of their head shaking, making it more practical.

[0047] As a further preferred technical solution, the device of the present application is also provided with a photovoltaic power generation device and a secondary battery, so as to be suitable for planting and vegetation protection application scenarios.

[0048] This solution provides energy-saving and environmentally friendly technical solutions for outdoor use where power supply is inconvenient.

[0049] As a further preferred technical solution, the method of the present application further includes the following steps in no particular order, which can be arranged and combined with each other and can be arranged and combined with steps S1 to S4:

[0050] S4. Irregular sound drive: The central processor generates multiple random numbers corresponding to the starting frequency, frequency conversion rule, starting amplitude, amplitude change rule, and time parameters of the sound drive. The central processor drives the sound generator according to the above parameters;

[0051] S5. Threatening Sound Drive: The central processing unit generates multiple random numbers corresponding to the starting frequency of the sound drive, the frequency conversion rule, and the parameters of this step time. During this step time, the central processing unit drives the sound generator according to the rule that the sound power gradually decreases from the maximum amplitude, or according to the rule that the sound power gradually increases from a certain amplitude (0-80% of the maximum sound power) to the maximum, to simulate the sound effect of a predator's sudden attack;

[0052] S6. Irregular light drive: The central processor generates multiple random numbers corresponding to the starting light intensity of the light drive, the light intensity conversion rule, and the time parameters of this step. The central processor drives the light generator to work according to the above parameters;

[0053] S7. Threatening Light Drive: The CPU generates multiple random numbers corresponding to the intensity change rule of the light drive and the parameters of this step. During this step, the CPU drives the light generator according to the rule that the light intensity gradually decreases from the maximum amplitude, or according to the rule that the light intensity gradually increases from a certain amplitude (0-80% of the maximum light intensity) to the maximum intensity, to simulate the visual effect of a predator's sudden attack.

[0054] S8. Mute: The CPU disables the sound generator;

[0055] S9. Light off: The central processing unit prohibits the light generator from working.

[0056] In this solution, multiple driving modes of the acoustic and optical generators are provided, including:

[0057] S4 is driven by irregular sound, aiming to create a completely irregular sound field and cause unexpected disturbances to the target object.

[0058] The S5 is driven by threatening sounds, using sudden changes in sound power, and pursuing unexpected frequencies, variations, and durations to provide sudden acoustic disturbances. This can simulate the sound effects of an incoming enemy attack (e.g., a "wow" sound rapidly approaching from a distance, a "wow" sound rapidly passing by), targeting pests with hearing. If the sound frequency is in the ultrasonic range, the sudden ultrasonic waves can also cause disturbances to insects that are sensitive to touch but cannot hear.

[0059] S6 is a random light drive, which pursues completely random and unexpected light disturbances towards the target object;

[0060] The S7 is a scare light driver that uses sudden changes in light intensity and unexpected variables to provide sudden light disturbances. It can simulate the light effects of a sudden enemy attack (such as a figure rapidly approaching from a distance or passing by), targeting pests with vision.

[0061] S8 and S9 are silent and light-off drives, respectively, that is, they do not work. They are used to insert a period of silence when the above driving sub-modes are used in combination. ①A serves as part of the sound and light effect; ② can be combined with S4 and / or S6 to provide a surprise effect, that is: after a long period of S4 and / or S6, silence is suddenly implemented to simulate the terrifying effect of an impending enemy attack; ③ can be combined with S5 and / or S7 to provide a surprise effect, that is: in a long period of silence, a sudden burst of sound and / or light intimidation suddenly breaks out to simulate the effect of an impending enemy attack.

[0062] This solution features sound and / or light generators, providing a disruptive and disturbing effect. Compared to traditional mechanical pest repellents, this solution significantly outperforms conventional mechanical pest repellents by simulating an actual enemy attack in multiple modes. Combined with the air supply device's simulated gusts and gusts of wind, this provides an immersive experience for the repelled creatures, resulting in significantly improved repellent effectiveness.

[0070] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0071] Example 1 - Dual-wind wheel sudden air supply and damage repellent device

[0072] like Figure 1 As shown, the device A is composed of a left air cover 1, a right air cover 2, a left impeller 3, a right impeller 4, a working head 5, a base 6, etc., wherein:

[0073] The left and right hoods 1 and 2 are both grating structures with bars 11 and 12, and fixing ears 12 and 22. The function of each hood is to shield the impeller installed behind it to prevent the impeller from injuring people or objects when rotating at high speed; the function of the fixing ears is to fix the hood to the work head;

[0074] The left impeller 3 and the right impeller 4 are rotary impellers, each having a hub in the center thereof, and a fixing hole (not shown) in the center of the hub;

[0075] The working head 5 is a double-socket fan body, which is provided with a fan shell 51, two fan chambers 50 for installing impellers, a swing shaft 56, and a slip ring 57 fixed to the swing shaft 56. The slip ring 57 is electrically connected to the control circuit board (not shown) installed inside the working head. Each fan chamber 50 is provided with a plurality of spokes 52 for fixing each drive motor 53 and a buckle 54 for fixing the wind cover. A motor output shaft 55 is provided in the center of each drive motor 53. The left impeller 3 and the right impeller 4 are fixed to the motor output shaft 55 through fixing holes (not shown) on their hubs. When the drive motor 53 is working, it can drive the impeller to rotate. The working head 5 rigidly fixes the left and right impellers into one body.

[0076] The base 6 is a disc-shaped structure with a flat bottom, which is used to sit stably on a table, countertop, etc.; a central protrusion on the upper part of the base 6 forms a bearing 61 for the support shaft, and the center of the bearing 61 is a hollow structure, and an elastic brush 62 is provided on the inner wall; a power socket 63 is provided on one side of the base 6; the power socket 63 is electrically connected to the elastic brush 62 through a wire; the working head 5 is inserted into the bearing 61 of the base 6 through the swing shaft 56, so that the working head 5 can rotate around the bearing 61. At the same time, the slip ring 57 on the swing shaft 56 is one-to-one connected to the elastic brush 62 on the inner wall of the bearing 61, realizing the electrical connection between the slip ring 57 and the elastic brush 62, and transmitting the electrical energy from the power socket 63 to the control circuit board through the elastic brush 62→slip ring 57.

[0077] During operation, power is transmitted to a control circuit board (not shown) through the power socket 63, elastic brushes 62, and slip rings 57. The circuit board then electrically connects the drive motors 53 of each wind wheel. The control circuit board (not shown) houses a central processing unit (CPU) and drive circuits (not shown) for each drive motor 53. When the CPU applies balanced drive signals to each drive motor 53, the rotation speeds of the wind wheels are consistent, and the reaction forces and torques exerted by the air on each wind wheel are consistent. The working head 5 is subjected to balanced forces and is in a constant speed or stationary state. This device A rotates smoothly and delivers air, or delivers air in a fixed direction. When the CPU applies unbalanced drive signals to each drive motor 53, the working head 5 is subjected to unbalanced forces, experiencing acceleration along the support axis, and the air delivery device changes from a fixed to a gradually increasing speed. The CPU, using the aforementioned basic drive rules, changes or fixes the orientation of the working head, thereby determining the air delivery direction of this device A.

[0078] Compared with the traditional fan shaking mechanism, this device does not require a special deceleration + shaking rigid drive mechanism, and the shaking power comes from the reaction force of the air, which is a soft drive. Therefore, it has a simple structure and a low failure rate. Especially in applications such as breeding, animal husbandry, and outdoor activities, the environment is complex and unpredictable obstacles and debris may appear at any time. The shaking technology of traditional fans may be hindered at any time, but this device A can easily cope with it without causing motor jams and other failures due to accidents.

[0079] The central controller can flexibly call the following steps as needed to achieve irregular air supply (simulating natural wind) or simulate the sudden fan effect of a hand-cranked fan. It can not only provide natural wind cooling and heat relief services, but also provide sudden air supply randomly or regularly, 360° without dead angle scanning or fixed direction to simulate sudden fanning, flapping and other pest-repelling actions. It can also use the random and rapid rotation of the working head to provide random and arbitrarily changing wind force (simulating a hand-cranked fan) in an alternating manner of positive wind and side wind to avoid the low experience caused by direct blowing.

[0080] S1. Balanced Drive: The central processing unit provides balanced electrical signals to the drive circuits of each impeller drive motor, balancing the driving torque of each impeller on the air, thereby keeping the working head stationary relative to the base or driving the working head to rotate at a constant speed along the support shaft;

[0081] S2. Micro-differential drive: The central processing unit provides short-term or micro-differential unbalanced electrical signals to the drive circuits of each wind rotor drive motor, causing a short-term or micro-differential difference in the driving torque of each wind rotor on the air, thereby causing the working head to generate a short-term or micro-differential acceleration along the support shaft;

[0082] S3. Large differential drive: The central processing unit provides a braking signal or a reverse driving signal to at least one wind wheel drive motor, so that the driving torque of each wind wheel on the air produces a large difference, thereby driving the working head to rotate rapidly along the support shaft.

[0083] Obviously, the implementation of this embodiment has the following obvious advantages:

[0084] 1) It breaks through the design of the traditional air supply device that uses a speed reducer to rigidly drive the shaking and swinging structure. The structure is simplified and the motor is prevented from stalling due to obstacles or resistance during the rotation of the working head.

[0085] 2) It breaks through the technical problem of traditional technology that is limited by the rotational inertia of the wind wheel and cannot achieve rapid fan. The central processor can use different driving signals of each wind wheel to simulate the effects of natural wind, rapid fan, slow fan, etc., which can not only provide a high-experience heat-removing and cooling service through natural wind, but also provide harm-repelling services through rapid fan.

[0086] Example 2 - Double-impedance straight-arm unbalanced sudden air supply and damage control device

[0087] like Figure 2 As shown, the device B consists of a working head (composed of a working wind wheel module M1, an adjusting wind wheel module M2, a bracket M21, a control circuit board, a human-machine interaction device P1, etc.), a support shaft 7, a base 6, etc., wherein:

[0088] The internal structure of the working wind wheel module M1 and the regulating wind wheel module M2 can be referred to Figure 1 , are assembled from fan shell, impeller, spokes, drive motor, etc.;

[0089] The bracket M21 rigidly connects the working wind wheel module M1 and the regulating wind wheel module M2 into one, forming a working head. The working head is connected to the base 6 through the swing shaft 7, so that the working head can rotate around the support shaft 7.

[0090] refer to Figure 1 , a swing shaft (not shown) and a slip ring (not shown) are provided in the support shaft 7, and a bearing (not shown) and an elastic brush (not shown) are provided on the corresponding base 6. A power socket 63 is provided on the base 6. Power is provided from the power socket 63 to the present device B, and is transmitted to the control circuit board inside the working head via the elastic brush (not shown) and the slip ring (not shown), and then is controllably transmitted to the working wind wheel module M1 and the regulating wind wheel module M2 via the control circuit board;

[0091] The human-machine interaction device P1 located above the support shaft 7 is electrically connected to the control circuit board (not shown) inside the working head, and is used to receive the operator's operation and display the operating status;

[0092] The size and power of the working wind wheel module M1 are greater than those of the regulating wind wheel module M2, and the two are arranged in parallel, that is, the air outlet directions are parallel.

[0093] During operation, the combined reaction forces exerted by the working rotor module M1 and the regulating rotor module M2 on the air are F1 and F2, respectively, and the lengths of their lever arms are L1 and L2, respectively. Due to the different sizes and powers of the working rotor module M1 and the regulating rotor module M2, the combined reaction force F1≠F2 on the air is unequal. To maintain force balance between the two rotor modules, this device B is designed as an unbalanced straight-arm structure. That is, the working rotor module M1 and the regulating rotor module M2 are arranged in parallel, but with different lever arms (L1≠L2), such that F1﹒L1=F2﹒L2.

[0094] Because the size and power of the regulating impeller module M2 are much smaller than those of the working impeller module M1, its response speed to changes in the drive signal from the central controller is also much faster than that of the working impeller module M1. Therefore, by adjusting the low-power, small-sized, and fast-responding regulating impeller module M2, this device B can quickly adjust the force applied to the entire working head, achieving rapid rotation of the working head and the actual effect of rapid fanning and flapping air supply.

[0095] In summary, after implementation, this embodiment has the advantages of Embodiment 1 and also has the following advantages:

[0096] 1) The adjustment response speed is faster and the sudden effect achieved is better;

[0097] 2) Control high power with low power, which can improve the utilization rate of electric energy.

[0098] Example 3 - Double-impedance non-straight-arm non-balanced sudden air supply and damage-repelling device

[0099] like Figure 3 As shown, the device C consists of a working head (composed of a working wind wheel module M1, an adjusting wind wheel module M2, a bracket M21, a control circuit board, a human-machine interaction device P1, etc.), a support shaft 7, a base 6, etc., wherein:

[0100] The internal structure of the working wind wheel module M1 and the regulating wind wheel module M2 can be referred to Figure 1 , are assembled from fan shell, impeller, spokes, drive motor, etc.;

[0101] The bracket M21 rigidly connects the working wind wheel module M1 and the regulating wind wheel module M2 into one, forming a working head. The working head is connected to the base 6 through the swing shaft 7, so that the working head can rotate around the support shaft 7.

[0102] refer to Figure 1 , a swing shaft (not shown) and a slip ring (not shown) are provided in the support shaft 7, and a bearing (not shown) and an elastic brush (not shown) are provided on the corresponding base 6. A power socket 63 is provided on the base 6. Power is provided from the power socket 63 to the present device B, and is transmitted to the control circuit board inside the working head via the elastic brush (not shown) and the slip ring (not shown), and then is controllably transmitted to the working wind wheel module M1 and the regulating wind wheel module M2 via the control circuit board;

[0103] The human-machine interaction device P1 located above the support shaft 7 is electrically connected to the control circuit board (not shown) inside the working head, and is used to receive the operator's operation and display the operating status;

[0104] The size and power of the working wind wheel module M1 are greater than those of the regulating wind wheel module M2. The two are arranged non-parallel, that is, there is a certain angle between the air outlet directions.

[0105] During operation, the combined reaction forces exerted on the air by the working rotor module M1 and the regulating rotor module M2 are F1 and F2, respectively. Since the two are not parallel, the component force F1y of F1 in the direction parallel to F2 acts as a countervailing force to F2. Correspondingly, the effective lever lengths of both are L1 and L2, respectively. Due to the different sizes and powers of the working rotor module M1 and the regulating rotor module M2, the combined reaction force F1 ≠ F2 on the air. To maintain force balance between the two rotor modules, this device B is designed as an unbalanced, non-straight-arm structure. That is, the working rotor module M1 and the regulating rotor module M2 are arranged non-parallel, but F1﹒L1=F2﹒L2.

[0106] Compared with Embodiment 2, since the working wind wheel module M1 and the adjusting wind wheel module M2 are arranged non-parallelly, in the direction parallel to the resultant force of the reaction on the air, the corresponding component force F1y of the working wind wheel module M1 < F1. Therefore, to balance the torque between M1 and M2, the lever arm of the adjusting wheel M2 can be shorter. That is: The device C can use a shorter lever arm of the adjusting wheel to adjust the working wheel, which can make the volume of the device C smaller, the working radius occupied during rotation smaller, the control more flexible, or an adjusting wheel with a smaller size and smaller power can be used to adjust the working wheel.

[0107] Similar to Embodiment 2, since the size and power of the adjusting wind wheel module M2 are much smaller than those of the working wind wheel module M1, its response speed to changes in the drive signal from the central controller is also much faster than that of the working wind wheel module M1. Therefore, the device C can quickly adjust the force on the entire working head by adjusting the small-power, small-size, and fast-response adjusting wind wheel module M2, and can achieve the rapid rotation of the working head, achieving the actual effect of rapid fanning and flapping air supply.

[0108] In summary, after the implementation of this embodiment, in addition to having the advantages of Embodiments 1 and 2, it also has:

[0109] 1) The overall volume of the machine is smaller, and the working radius is smaller (occupying less working space);

[0110] 2) The size and power of the adjusting wheel can be smaller, the cost is lower, and the control is more flexible.

[0111] Embodiment 4 - Working Head with Acoustic-Optical Generation Device

[0112] See Figure 4 , the working head 5 has 2 wind wheels. Between the fan shells 51 where the two wind wheels are located, there are a sound generator 58 and a light generator 59. Correspondingly, inside the working head 5, there is a control circuit board (not shown). On the control circuit board, there are a sound drive circuit (not shown) and a light drive circuit (not shown), which are electrically connected to the sound generator 58 and the light generator 59 respectively.

[0113] Compared with Embodiments 1, 2, and 3, in this embodiment, after the implementation of this embodiment, the sound generator 58 and the light generator 59 provide the hardware basis for adding the functions of sound驱赶 and light驱赶 to this device.配合 the control strategy of the control circuit board for the sound generator 58 and the light generator 59, it can cooperate with the shaking and variable wind speed process of the working head to provide the effect of disturbing and startling harmful substances, achieving a better harmful substance驱赶 effect than traditional physical驱赶 devices.

[0114] Embodiment 5 - Photoelectric Position Sensor Arranged on the Support Shaft

[0115] As Figure 5As shown, as part of a sudden air supply and damage repellent device, this device D is equipped with a slip ring 57 for transmitting electrical energy and a photoelectric position sensor for sensing the rotation angle and speed of the swing shaft 56 on the working head. The photoelectric position sensor includes a disc-shaped baffle 8 fixed vertically to the swing shaft 56, and a light source plate 84 and a detection plate 83 fixed to both sides of the baffle 8.

[0116] The baffle 8 is made of an opaque material. On its edge, a plurality of light-transmitting grooves 81 are evenly distributed on the same radius with the swing shaft 56 as the center. At a different radius from the grooves 81, a marking groove 82 is provided.

[0117] The light source board 84 and the detection board 83 are both electrically connected to the control circuit board;

[0118] The light source board 84 is provided with a light-emitting element (not shown for angle reasons), which is aligned with the seal 81 and the mark slot 82 on the baffle 8 so that light can pass through the seal slot 81 and the mark slot 82 and reach the detection plate 83 on the opposite side. The light source board 84 is also provided with a current control circuit (not shown) for the light-emitting element.

[0119] The detection board 83 is fixedly installed relative to the light source board 84, and is provided with a dense groove photosensitive element 85 facing the light-emitting element on 83, and a flag photosensitive element 86. The detection board 83 is also provided with a signal processing circuit (not shown) for converting the state change of the photosensitive element into a switch signal and transmitting it to the control circuit board so that the central processing unit on it can detect the rotation angle and speed of the pendulum shaft in real time.

[0120] Compared with embodiments 1, 2, 3, and 4, in this embodiment, after implementation, the central controller can obtain the angle and speed of the working head in real time, so that the control system forms a closed loop.

[0121] 1) The central controller can output more accurate control signals and make timely adjustments in a short time, so that the working head can get a faster response;

[0122] 2) Generally, as the equipment is used for a longer time, its performance will decline due to wear, aging, etc. This embodiment closes the control loop and can adjust the control strategy in real time according to the actual measurement results, compensating for wear, aging, etc. through control measurement, so that the equipment always maintains the optimal control effect.

[0123] Example 6 - Air supply and pest repellent device with manually adjustable swing head angle

[0124] like Figure 6As shown, the base 6 of the air supply and repellent device is the same as in Example 1, in which a bearing 61 for supporting the shaft is formed by a protrusion in the upper center of the disc seat 60, and an elastic brush 62 is provided on the inner wall of the bearing 61. A power socket 63 is provided on one side of the base 6; in addition, a plurality of gear holes 64 are provided on the upper side of the disc seat 60, and a stop column 65 is provided, wherein the stop column 65 can be fixed to any gear hole 64 and is higher than the upper surface of the disc seat 60 by a distance.

[0125] refer to Figure 1 、 Figure 2 、 Figure 3 When working, the working head of the air supply and pest repellent device rotates along the support shaft under the drive of the central controller. When it rotates to a certain angle, the bottom of the working head touches the blocking column 65, and the rotation action is blocked. The working head stops rotating, thereby achieving the purpose of limiting the rotation angle of the working head.

[0126] If the stopper 65 is manually inserted into different gear holes 64, the rotation angle of the working head can be limited to different angular positions. That is, after the present embodiment is implemented, the rotation angle of the working head can be manually arbitrarily limited to be within a suitable range.

[0127] If the technology of Example 5 is used, the central processing unit can detect in real time when the working head suddenly changes from normal speed to 0 (rotation is blocked), i.e., recognize that the limit has been reached. The central processing unit can then change the control strategy to rotate the working head in the opposite direction until it encounters another blocking post 65. In this way, the rotation range of the air supply and pest repellent device can be arbitrarily limited by manually adjusting the insertion position of the blocking post 65.

[0128] In most usage scenarios, such as when used by a single person or when the fan is placed in a corner, the fixed swing range of traditional fan technology results in a large amount of wasted airflow, resulting in low airflow utilization and a poor user experience. This embodiment can effectively alleviate the drawbacks of such scenarios.

[0129] Example 7 - Control strategy for simulating rapid fan effects

[0130] Taking the case where the air supply and damage repellent device is provided with two wind wheels as an example, the central controller controls according to the following steps:

[0131] F1. Energy storage: Provides balanced drive for the two wind turbine motors, ensuring that at least one of the wind turbines (working rotors) reaches the highest speed (or the speed agreed upon through human-machine interaction), and that the working head remains stationary (not rotating).

[0132] F2. Waiting for command: Maintain the state of step F1 for a period of time T1;

[0133] F3. Rapid fan: brakes or reverses one of the wind wheels (regulating wheel), quickly destroying the torque balance between the two wind wheels and causing the working head to rotate rapidly.

[0134] F4. Braking: After detecting that the working head has turned to the target angle, or after a delay of T2 after executing the F3 action, the drive of the braked or reversed wind wheel is restored and made greater than the drive amount in the F2 step, so that the working head stops rotating.

[0135] The core idea of ​​this embodiment is: step F1 stores energy for the wind wheel so that it can provide sufficient wind force in the subsequent steps; step F2 maintains a windless state for a certain period of time in the area to be rapidly fanned, so as to provide a contrast effect for the subsequent rapid fanning; step F3 enables the working head to carry the highest (or the value agreed upon by human-computer interaction) wind force and blow rapidly towards the target direction, completing the rapid fanning action in that direction; step F4 is the end of the rapid fanning action.

[0136] If the technical solutions of Examples 2 and 3 are adopted, that is, a small-sized, low-power regulating wheel is used to control a large-sized, high-power working wind wheel, then since the rotational inertia of the small wind wheel is much smaller than that of the large wind wheel, its braking or reverse speed is faster, and a better quick turn effect can be obtained.

[0137] As can be seen, after real-time operation, this embodiment achieves rapid swinging of the working head (in the air supply direction) through the rapid imbalance of torque between the two impellers, which can simulate the rapid fanning action of a hand-cranked fan, making it an optimal action for relieving summer heat and driving away harmful substances, and achieving the best effect. This is something that the swinging technology of traditional fans cannot achieve, and is one of the outstanding technical effects of this invention.

[0138] Example 8 - Control Strategy for Simulating the Sound of an Incoming Enemy Attack

[0139] Taking the case where the air supply and damage repellent device is provided with two wind wheels as an example, the central controller controls according to the following steps:

[0140] E1. Stop the sound generator (silent);

[0141] E2. Generate three random numbers, corresponding to the starting frequency of the acoustic drive, the frequency variation rule, and the duration of the current cycle;

[0142] E3. Drive the sound generator to operate by determining parameters according to E2, based on the rule that the sound power gradually decays from the highest amplitude, or the sound power gradually increases from a certain amplitude (0-80% of the highest sound power) to the highest amplitude;

[0143] E4. Stop the sound generator (silence).

[0144] The core idea of ​​this embodiment is: in a silent state, a short-term (the duration of this cycle determined in step E2) sound disturbance is suddenly released to disturb harmful objects with hearing in real time.

[0145] If the rapid fanning action of Example 7 is combined with the steps of this embodiment and the F3 step of Example 7 is started synchronously, the acoustic disturbance can be caused to suddenly appear in an area in a specified direction under the influence of the wind, thereby simulating the effect of an attack by natural enemies, effectively disturbing harmful objects in that direction, and achieving a better pest-repelling effect.

[0146] In other embodiments, it is possible to:

[0147] 1) Use more than two wind wheels to obtain more options for use;

[0148] 2) Set up a light generator and match it with the corresponding driving strategy to simulate the flashing effect of the natural enemy attacking, or simulate the effect during the day to enhance the pest repellent effect;

[0149] 3) Set up human-computer interaction in remote control mode, etc.

[0150] In addition, in the present invention, unless otherwise clearly specified and limited, the term "and / or" means: either of the two situations connected by the term is selected, or both are selected.

[0151] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention's description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
