[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Reference Figure 1 , showing the first state appearance diagram of a circulating fan dust baffle device of the present invention; referring to Figure 2, showing a schematic diagram of the first state structure of a circulating fan dust baffle device of the present invention; referring to Figure 3 , showing the appearance of a circulating fan dust baffle device in the second state of the present invention; referring to Figure 4 , shows a schematic diagram of the second state structure of a circulating fan dust baffle device of the present invention; specifically, it may include the following components:

[0041] The baffle 100 is arranged between the air duct plates on both sides of the circulation fan;

[0042] A connecting rod assembly 200, one end of which is connected to one side of the baffle 100;

[0043] The driving assembly 300 is connected to the other end of the connecting rod assembly 200, and is used to drive the baffle 100 to open when the circulation fan is running, and to drive the baffle 100 to close when the circulation fan is closed, so as to close the circulation fan.

[0044] In an embodiment of the present invention, the dust baffle 100 device of a circulation fan may include a baffle 100, a connecting rod assembly 200 and a driving assembly 300. The driving assembly 300 is an active component, which drives the baffle 100 to move through the connecting rod assembly 200. The baffle 100 is arranged between the air duct plates on both sides of the circulation fan, that is, one side of the baffle 100 is connected to the air duct plate on one side of the circulation fan, and the other side of the baffle 100 is connected to the air duct plate on the other side of the circulation fan. The connecting rod assembly 200 is an intermediate connecting component, one end of which is connected to one side of the baffle 100, and the other end is connected to the other end of the driving assembly 300. The driving assembly 300 controls the movement of the baffle 100 based on the operating state of the circulation fan. Figure 2 and Figure 4 When the circulation fan is running, the driving assembly 300 drives the baffle 100 to open to ensure that the air outlet is unobstructed. Figure 1 and Figure 3 When the circulation fan is turned off, the driving assembly 300 drives the baffle 100 to close, completely covering the air outlet to close the circulation fan.

[0045] When the circulation fan is turned on, the blower or fan built into the circulation fan is turned on by Figure 5 The air duct shown blows out the fresh air, and then when the baffle 100 is opened, it is output from the air outlet to realize the transportation of the fresh air.

[0046] Further, please refer to Figure 6 The driving assembly 300 is eccentrically connected to the connecting rod assembly 200. The eccentric connection between the driving assembly 300 and the connecting rod assembly 200 can drive the connecting rod assembly 200 more efficiently, thereby better driving the baffle 100 to move, thereby blocking dust and keeping the air outlet open.

[0047] Furthermore, the number of the baffles 100, the connecting rod assembly 200 and the driving assembly 300 is the same, that is, one baffle 100 is driven by a corresponding and unique connecting rod assembly 200 and driving assembly 300, and each baffle 100 can be driven independently, so that the corresponding functions can be realized and the use requirements can be met.

[0048] Specifically, the baffle 100 includes:

[0049] A plate member is arranged between the air duct plates on both sides of the circulation fan;

[0050] The rotating shaft is arranged on the plate and connected to one end of the connecting rod assembly 200 .

[0051] In the embodiment of the present invention, the baffle 100 may include a plate and a rotating shaft. The plate is a thin plate-like part, which may be made of engineering plastic or metal material, and the embodiment of the present invention does not specifically limit this. The plate is arranged between the air duct plates on both sides of the circulation fan, and the rotating shaft is located on the plate, and the length of the rotating shaft is greater than the length of the plate, so that it can be connected to one end of the connecting rod assembly 200, which is convenient for driving the connecting rod assembly 200.

[0052] The plate is arc-shaped, and the arc matches the arc of the air duct plate of the circulation fan, so that the circulation can be better sealed and the air outlet can be better prevented from being blocked by dust.

[0053] Specifically, the connecting rod assembly 200 includes:

[0054] An active rod, one end of which is connected to the driving assembly 300;

[0055] A connecting rod, one end of which is connected to the other end of the active rod;

[0056] One end of the driven rod is connected to the other end of the connecting rod, and the other end is connected to the baffle 100 .

[0057] The connecting rod assembly 200 may be a multi-link structure, including an active rod, a connecting rod and a driven rod. The connecting rod is located between the active rod and the driven rod, that is, one end of the connecting rod is connected to the active rod, and the other end of the connecting rod is connected to the active rod. The active rod is connected to the driving assembly 300, and the driven rod is connected to the baffle 100. That is, during movement, the driving assembly 300 drives the active rod to move, the active rod drives the connecting rod to move, the connecting rod drives the driven rod to move, and the movement of the driven rod drives the baffle 100 to move, thereby realizing the opening and closing of the baffle 100.

[0058] Specifically, refer to Figure 7 , the driving assembly 300 comprises:

[0059] The motor is connected to the other end of the connecting rod assembly 200 and fixed on the air duct plate.

[0060] The driving assembly 300 may be composed of a motor assembly, the motor is fixed on the air duct plate, and the output end of the motor is connected to the connecting rod assembly 200, thereby driving the connecting rod assembly 200 to move.

[0061] Furthermore, the motor may be a micro motor, including the following types:

[0062] The basic principle of DC Micro Motor is to generate a magnetic field through direct current to drive the rotor to rotate.

[0063] A stepper micro motor is a motor that rotates at a certain step distance. It drives the motor to step by current pulses, and the angle of each step is fixed.

[0064] A servo micro motor is a motor with a feedback control system that can accurately control angle, speed, and position. Servo motors are usually equipped with sensors that can adjust their motion according to external signals.

[0065] AC Micro Motor uses the principle of electromagnetic induction to generate a rotating magnetic field in the stator, thereby driving the rotor to rotate.

[0066] The specific components include: stator, rotor, commutator, bearings and brushes. The stator is the fixed part of the micro motor, usually composed of electromagnetic coils, iron cores, etc., which plays the role of generating a magnetic field. The rotor is the rotating part of the micro motor, usually made of conductive materials (such as copper or aluminum), and rotates under the action of the magnetic field generated by the stator. The commutator is a device used to reverse the direction of the current to ensure that the motor can continue to rotate. The bearings are used to support the rotor, reduce friction, and ensure smooth rotation of the rotor. The brushes are used to contact the commutator to transfer current to the stator or rotor.

[0067] The working principles of different micro motors are as follows:

[0068] In a DC motor, current is conducted to the stator coils via brushes and a commutator, creating a magnetic field. The motor continues to turn because the direction of the current is constantly reversing.

[0069] A stepper motor controls the position of the rotor by activating the stator coils in steps. Each time a stator coil is activated, the rotor moves a fixed angle.

[0070] Servo motors use a feedback system to precisely control the movement of the rotor. The motor position, speed and other parameters are fed back to the control system in real time through sensors, and the controller adjusts the movement of the motor based on the feedback signal.

[0071] Further, the active rod is connected to the driving assembly 300 via screws, and / or,

[0072] The active rod is connected to the connecting rod by screws, and / or,

[0073] The driven rod is connected to the connecting rod by screws, and / or,

[0074] The driven rod is connected to the baffle 100 via screws.

[0075] In practical applications, the active rod and the driving assembly 300 can be connected by screws. The active rod and the connecting rod can be connected by screws. The driven rod and the connecting rod can be connected by screws. The driven rod and the baffle 100 can be connected by screws. The circulating fan dust baffle 100 device is conveniently and detachably connected by screws, thereby improving the efficiency of disassembly and assembly.

[0076] In an optional embodiment of the present invention, the circulating fan dust baffle 100 device further includes: a status indicator light, connected to the baffle 100 and used to display the status of the baffle 100.

[0077] At least one status indicator light may be provided in the circulating fan dust baffle 100 device. The status indicator light is electrically connected to the baffle 100, and the status indicator light displays the status of the baffle 100. The user can intuitively understand the status of the baffle 100 through the status of the status indicator light. For example, when the baffle 100 is in an open state, the status indicator light is on; when the baffle 100 is in a closed state, the status indicator light is off.

[0078] In an optional example, the status indicator light can use a light emitting diode (LED), which is a semiconductor device that can convert electrical energy into light energy. The working principle is that the flow of current causes electrons and holes in the semiconductor material to recombine, thereby releasing energy and generating photons (i.e., light). Specifically, LED is a diode composed of semiconductor materials, and its structure is similar to that of an ordinary diode, with two electrodes (anode and cathode). When current passes through the LED, electrons flow from the cathode to the anode and recombine with holes (missing positions of electrons) inside the semiconductor material. This recombination process releases energy, and part of the energy is released in the form of light. When current is input into the LED from the power supply, electrons enter the LED at the cathode and flow to the anode. In the semiconductor material, electrons recombine with holes and release energy. This released energy is emitted in the form of photons, which is the principle of LED light emission. The color (wavelength) of the emitted light depends on the energy band structure of the semiconductor material, and different materials emit light of different colors.

[0079] The components of LED mainly include: Semiconductor chip: This is the core of LED and determines the color of LED light. Usually III-V semiconductor materials (such as gallium arsenide GaAs, gallium nitride GaN, etc.) are used. Different materials will cause different wavelengths of light to be emitted. Lead frame: Used to connect the semiconductor chip to the external circuit to ensure the flow of current. Lens (or package): Protect the semiconductor chip from damage by the external environment and help scatter or focus light. Packaging material: Usually epoxy resin or silicone, used to encapsulate and protect LED chips. Heat dissipation system: LED will generate a certain amount of heat when working, so a heat dissipation design is required to avoid overheating and damage to the LED chip.

[0080] In summary, the assembly and operation process of the circulating fan dust baffle 100 device is described:

[0081] When the air ducts on both sides are not assembled, first install the baffle 100 at the corresponding hole position of the left air duct plate, and then install the driven rod on the rotating shaft of the baffle 100. The driven rod is connected to the active rod through a connecting rod, and a motor is installed at the other end of the active rod. Then, the motor is fixed and installed at the corresponding position of the air duct plate and screwed. Each motor controls a baffle 100 respectively.

[0082] Each baffle 100 is linked to the switch of the circulation fan through the motor. When the circulation fan is turned off, the motor drives the active rod to move, and the baffle 100 is automatically closed through the connecting rod and the driven rod to completely cover the air outlet; when the circulation fan is turned on, the motor drives the active rod, and the baffle 100 is automatically opened through the connecting rod and the driven rod to ensure that the air outlet is unobstructed.

[0083] In the embodiment of the present invention, a baffle is arranged between the air duct plates on both sides of the circulation fan; a connecting rod assembly has one end connected to one side of the baffle; and a driving assembly is connected to the other end of the connecting rod assembly, and is used to drive the baffle to open when the circulation fan is running, and to drive the baffle to close when the circulation fan is closed, so as to close the circulation fan.

When the circulation fan is closed, the driving assembly drives the baffle to close automatically to completely cover the air outlet; when the circulation fan is running, the driving assembly drives the baffle to open automatically to ensure that the air outlet is unobstructed; dust accumulation at the air outlet of the circulation fan can be reduced, ensuring that the air blown out when the user turns on the machine is cleaner, and extending the service life of the circulation fan, reducing the maintenance cost caused by dust accumulation.

[0085] The above-mentioned circulating fan dust baffle device is arranged on the housing. Through the circulating fan dust baffle device, it is automatically closed when the circulating fan is turned off, effectively protecting the air duct from dust intrusion; when it is turned on, the baffle is automatically opened to ensure that the normal use of the fan is not affected.

[0109] An embodiment of the present invention discloses a circulation fan, comprising the fan casing as described above.

[0110] A circulation fan is an electric device used for air circulation and improving indoor ventilation, and is mainly used to improve the comfort of the environment through the circulation and flow of air. The circulation fan in the embodiment of the present invention includes the fan housing described above; it may also include a fan motor and fan blades that operate together.

[0111] The main function of a circulation fan is to make the air in the room flow more evenly by circulating it around the room. This helps to reduce air stagnation and prevent certain places from being too hot or too cold, thereby improving the ventilation of the room. Unlike ordinary fans, circulation fans are usually designed with a larger fan blade, a wider range of wind speed settings, and the direction of the fan's wind propagation can usually be adjusted to deliver air to every corner of the room.

[0112] The working principle of the circulation fan usually includes the following points:

[0113] Air Circulation: Circulation fans move air around a room using a built-in blower or fan. They are usually gentle and distribute air more evenly by creating a natural air flow.

[0114] Multi-angle wind direction adjustment: Many circulation fans support multi-angle adjustment, which can more flexibly adjust the air blowing direction. Some products even support vertical and horizontal bidirectional adjustment.

[0115] Wind speed adjustment: There are usually multiple wind speed levels, and users can adjust the strength of air flow as needed to adapt to different usage environments.

[0116] The main functions of the circulation fan include:

[0117] Air circulation and temperature balance: The main function of the circulation fan is to help indoor air flow, especially in summer or winter to help air convection and balance the temperature of various areas of the room. For example, in summer, through air circulation, the air in the air-conditioned room can be prevented from being locally cold due to concentrated cold air, thereby increasing comfort.

[0118] Improve indoor humidity: In a humid environment, air circulation can help moisture dissipate better and avoid problems such as musty odors caused by excessive humidity.

[0119] Air purification: Some circulation fans are also equipped with air filtration systems, such as built-in HEPA filters or negative ion generators, which can help freshen the air and remove indoor dust, bacteria, odors, etc.

[0120] Power saving and energy saving: Compared with air conditioners, circulation fans consume less electricity. In the process of air circulation, it can enhance air flow through wind power without relying too much on electricity consumption for heating or cooling.

[0121] Advantages of circulating fans:

[0122] Low energy consumption: Compared with large household appliances such as air conditioners, circulation fans have lower energy consumption and more economical operating costs.

[0123] Easy to install and use: Users can easily place it where they need it, adjust the wind direction, and even set the timing, etc.

[0124] Improve air quality: In addition to general air circulation functions, many modern circulation fans are equipped with air purification, negative ion release and other functions to further improve indoor air quality.

[0125] Relatively quiet: Most circulation fans produce low noise when in operation and are suitable for use in places where a quiet environment is required, such as bedrooms and offices.

[0126] The circulation fan type can be any of the following:

[0127] Tower type circulation fan: This type of circulation fan is taller and more compact, suitable for placement in limited spaces. It has more uniform wind force and is commonly used in homes and offices.

[0128] Vertical circulation fans: Vertical fans usually have stronger wind power and a wide adjustment range. They are suitable for larger spaces and can provide air flow in multiple directions.

[0129] Desktop circulation fan: This type of circulation fan is smaller in size and is usually suitable for desktop use. It can provide local air flow and is suitable for personal use.

[0130] Wall-mounted circulation fans: This type of fan is mounted on the wall and is suitable for places with limited space. It can provide air circulation without taking up floor space.

[0131] Specifically, the circulating fan dust baffle device comprises:

[0132] The baffle is arranged between the air duct plates on both sides of the circulation fan;

[0133] A connecting rod assembly, one end of which is connected to one side of the baffle;

[0134] A driving assembly is connected to the other end of the connecting rod assembly and is used to drive the baffle to open when the circulating fan is running, and to drive the baffle to close when the circulating fan is closed, so as to close the circulating fan.

[0153] In the embodiment of the present invention, a baffle is arranged between the air duct plates on both sides of the circulation fan; a connecting rod assembly has one end connected to one side of the baffle; and a driving assembly is connected to the other end of the connecting rod assembly, and is used to drive the baffle to open when the circulation fan is running, and to drive the baffle to close when the circulation fan is closed, so as to close the circulation fan.

[0154] An embodiment of the present invention discloses a fresh air system, comprising the circulation fan as described above.

[0155] In the fresh air system of the embodiment of the present invention, a circulation fan is provided, which can adjust the air in the deployment environment of the fresh air system so that the fresh air system meets the use requirements.

[0156] In some examples, the fresh air system can be a home air conditioning system, a commercial / office environment ventilation system, a smart home system, a temperature control and ventilation system, an air purification system, a greenhouse and agricultural planting system, a data center and server room ventilation system, a laboratory environment ventilation system, a vehicle air conditioning and ventilation system, etc.

[0157] A home air conditioning system generally consists of an indoor unit and an outdoor unit. The indoor unit is responsible for regulating the indoor temperature, humidity and air quality, while the outdoor unit handles heat exchange through components such as compressors and condensers. Air conditioning cools or heats through the flow of refrigerant. Combined with a circulating fan: One of the main problems with home air conditioning is uneven air flow, which leads to inconsistent temperatures. Using a circulating fan can help the air flow evenly and avoid the phenomenon of "uneven cold and hot". For example, when the air conditioner is cooling, the cold air tends to concentrate below the air conditioner, while the hot air stagnates above. The circulating fan can push this part of the hot air back to the air conditioner outlet to help evenly distribute the temperature. Effect: Improve air conditioning efficiency and reduce energy consumption. Improve indoor air flow to ensure consistent temperature in each area. Prevent air stagnation around the air outlet of the air conditioner.

[0158] The smart home system connects various devices in the home (such as air conditioners, lights, security, curtains, etc.) through Internet technology, and users can control the devices through mobile phones, voice assistants, etc. Smart home systems usually integrate sensors, controllers, actuators, etc. Combined with circulation fans: In smart homes, circulation fans can be used as part of smart devices and linked with other devices through Wi-Fi or Bluetooth. For example, a temperature sensor can be set to automatically sense changes in indoor temperature. When the temperature is too high or too low, the circulation fan is automatically started to even out the air flow. Users can also adjust the wind speed and time the start through the mobile phone APP. Effect: Automated control to improve comfort. Link with air conditioners, humidifiers and other equipment to improve environmental comfort. More convenient operation through voice control.

[0159] Commercial / office environment ventilation systems contain multiple air conditioning zones (such as split type, central air conditioning, etc.). In order to adapt to large areas of space, central air conditioning is often used in these places. Central air conditioning distributes air to different areas through a duct system. Combined with circulating fans: In large commercial spaces, air conditioning often cannot ensure uniform air flow in every corner. Circulating fans can help promote airflow, thereby avoiding excessively high or low temperatures in some places. Especially in large open offices, circulating fans can assist air flow throughout the area, avoiding local air stagnation and excessive temperature differences. Effect: Improve the efficiency of the air conditioning system and reduce energy waste. Improve the comfort of employees and customers and create a more pleasant working environment. Reduce moisture and odor in the air and keep the indoor air fresh.

[0160] Temperature control and ventilation system (HVAC system) is a system that integrates heating, ventilation and air conditioning, and is widely used in commercial, industrial, medical and other places. The core function of this system is to regulate indoor temperature, humidity, air quality and air flow. Combined with circulation fans: HVAC systems usually include air handling units, duct systems, heating or cooling equipment, etc. Circulation fans can help improve the flow of air in the system, especially inside the building, to ensure that the air does not stagnate in certain areas, but is evenly distributed through the air ducts. Effect: Enhance air flow and optimize the overall performance of the HVAC system. Help regulate humidity and temperature to improve the comfort of the living or working environment. Reduce the energy consumption of the HVAC system and improve energy efficiency.

[0161] The air purification system removes pollutants from the air, including dust, bacteria, viruses, odors, smoke, etc., through filtration, adsorption, photocatalysis and other technologies. Modern air purifiers usually use technologies such as HEPA filters and activated carbon filters, and some devices also support UV light sterilization. Combined with a circulating fan: The efficiency of an air purifier is usually related to air circulation. A circulating fan can assist the air purifier in cleaning pollutants in the air more effectively. For example, using a circulating fan can speed up the flow of air, allowing the air purifier to process more air in a shorter time. Effect: Improve the working efficiency of the air purifier and expand the coverage of air cleaning. Accelerate the removal of pollutants and improve indoor air quality. Make the air purification process more efficient and ensure a healthy indoor environment.

[0162] Greenhouses and agricultural planting systems are designed to control the environment in which plants grow, including temperature, humidity, light, CO2 concentration, etc. Heating, ventilation, humidity control and supplemental lighting may be used in greenhouses to ensure that plants grow in the most ideal conditions. Combined with circulating fans: In greenhouses, circulating fans can be used to enhance air flow, reduce uneven distribution of heat or moisture, and avoid overheating or overhumidity in certain areas. In addition, circulating fans can help to enhance the uniform distribution of carbon dioxide concentration in the air, ensuring that plant photosynthesis is more effective. Effect: Improve the climate conditions in the greenhouse and help plants grow healthily. Reduce the occurrence of pests and diseases, maintain air flow, and reduce the breeding of humid environments. Improve the uniformity of CO2 concentration distribution in the greenhouse and promote plant photosynthesis.

[0163] Data center and server room ventilation systems, because servers generate a lot of heat when running, are usually equipped with sophisticated cooling systems (such as air conditioning, liquid cooling systems, etc.) to ensure that the equipment does not crash due to overheating. Combined with circulation fans: Circulation fans are used to help air flow and reduce heat retention in the room, especially in corners that are difficult to reach with air conditioners. By enhancing air convection, circulation fans can promote uniform air flow and ensure that the temperature in the room is as consistent as possible. Effect: Improve air flow in the room and improve cooling effect. Reduce the risk of equipment overheating and ensure stable operation of the server. Extend equipment life and reduce maintenance and downtime.

[0164] Laboratory Environmental Ventilation System Air quality and temperature control are critical, especially in biological, chemical, and physical laboratories. Air purification, HVAC, ventilation systems, and environmental monitoring equipment are common configurations. Combined with circulation fans: Circulation fans can enhance air flow in the laboratory, especially where harmful gases or chemicals may accumulate. By effectively promoting air exchange, circulation fans help keep the air fresh and reduce the accumulation of harmful gases or temperature and humidity fluctuations. Effect: Keep the laboratory air fresh and avoid the accumulation of harmful gases. Provide a uniform temperature and humidity environment, which is conducive to precise experiments. Improve air purification and ventilation effects to ensure the safety of the experimental environment.

[0165] The vehicle air conditioning and ventilation system regulates the temperature in the vehicle through compressors, condensers and other equipment, and cooperates with the ventilation system to circulate air. The air in the vehicle usually circulates through the vents, and the vehicle air conditioning system is usually equipped with heating and cooling functions. Combined with a circulating fan: The space in the vehicle is small and closed, and air is easily trapped. The circulating fan can help the air in the vehicle circulate, avoid odor accumulation, and improve the comfort of the owner and passengers. By promoting air flow in the vehicle, the circulating fan can help the air conditioner regulate the temperature more effectively. Effect: Improve the air circulation in the vehicle and reduce odor. Promote the air conditioning system to work more efficiently. Improve the comfort of passengers and reduce the stuffiness in the vehicle.
