Their main function is to generate airflow through the rotation of the wind wheel, which is used for air circulation and cooling of the indoor environment. However, the structural design of most traditional fans is relatively simple, and they usually adopt a single-direction air outlet method. This design has certain limitations in meeting the ventilation needs of local areas. Specifically, fans that outlet air in a single direction can usually only concentrate the airflow in a specific direction.

[0028] The present application is further described in detail below in conjunction with the accompanying drawings.

[0029] In one embodiment, if Figure 1 As shown, the present application discloses a filtering multi-sided air outlet fan, a filtering multi-sided air outlet fan, and the filtering multi-sided air outlet fan comprises: Support seat 1; A housing 2 connected to the support base 1; A control circuit board 3 is located inside the housing 2; A motor 4, one end of which is connected to one side of the housing 2, and the other end of which is connected to a wind wheel 5; The air chamber 6 is located inside the housing 2, and includes an air inlet 61, an air guide cavity 62, and a plurality of air outlets 63. The plurality of air outlets 63 are distributed along the circumference of the housing 2. The wind wheel 5 is located between the plurality of air outlets 63 and is arranged opposite to the air inlet 61 to form an air guide duct for air to enter from the air inlet 61, pass through the air guide cavity 62, and then exit at each of the air outlets 63. A filter component 7, located on the housing 2 and electrically connected to the control circuit board 3; The heating component 8 is located between the air outlet 63 and the housing 2 , and is electrically connected to the control circuit board 3 .

[0030] In this embodiment, the filtering multi-faceted air outlet fan is firmly connected to the housing 2 through the support base 1. The support base 1 provides stability and support for the entire device, and provides a reliable mechanical basis for the operation of the fan. After the housing 2 is connected to the support base 1, the external frame of the entire device is formed. The housing 2 contains key functional components, including a control circuit board 3, a motor 4, a wind wheel 5, a wind chamber 6, a filter component 7, and a heating component 8. The housing 2 not only protects the internal components, but also provides space support for the wind guide function of the wind chamber 6 and the operation of the filter component 7 through a reasonable internal structure layout.

[0031] The control circuit board 3 is located on the inner side of the housing 2. It realizes control and signal transmission of other functional components in the device through electrical connection, and is the control center of the entire device. It coordinates the working status of each component, such as adjusting the speed of the motor 4, monitoring the operating status of the filter component 7, and controlling the heating power of the heating component 8, so that the fan can achieve different functional modes according to environmental requirements. One end of the motor 4 is fixed to one side of the housing 2, and the other end is connected to the wind wheel 5, which is driven to rotate by the power transmission of the motor 4. As the core component of air flow, the wind wheel 5 is used to inhale external air into the air inlet 61 of the wind chamber 6, guide the airflow through the air guide cavity 62, and finally discharge it through multiple air outlets 63. The arrangement of the wind wheel 5 between the multiple air outlets 63 and the design opposite to the air inlet 61 enable the airflow to be evenly distributed to the circumference of the housing 2, providing a key technical guarantee for achieving uniform air discharge in multiple directions.

[0032] The air chamber 6 is located inside the casing 2 and is the main structure of the air flow channel, including an air inlet 61, an air guide cavity 62 and multiple air outlets 63. The air inlet 61 is responsible for introducing external air, the air guide cavity 62 guides and distributes the airflow, and the design of multiple air outlets 63 distributed along the circumference of the casing 2 ensures that the airflow can be evenly transported to all directions after passing through the air guide cavity 62. This design avoids the problem of air dead corners caused by the unidirectional air outlet of traditional fans, and effectively improves the uniformity and coverage of indoor air circulation. The role of the air chamber 6 is also reflected in its cooperation with the wind wheel 5. It can reduce the airflow resistance and improve the operating efficiency of the fan through reasonable air duct design.

[0033] The filter component 7 is mounted on the housing 2, and its working state is regulated by electrical connection with the control circuit board 3. The main function of the filter component 7 is to purify the air entering from the air inlet 61, filter out particulate matter and impurities in the air, and thus improve the indoor air quality. The coordinated installation of the filter component 7 and the housing 2 ensures the sealing of the filtering process and prevents unfiltered air from entering the air outlet 63. At the same time, the installation design of the filter component 7 is easy to disassemble and replace, which improves the maintenance convenience of the equipment.

[0034] The heating component 8 is located between the air outlet 63 and the housing 2, and is electrically connected to the control circuit board 3 to achieve linkage control. The main function of the heating component 8 is to heat and regulate the air discharged from the air outlet 63, and provide air outlet effects of different temperatures according to user needs. Its position design enables the heating component 8 to accurately control the temperature of the air before it is discharged, and at the same time, through the signal feedback of the control circuit board 3, the safety and stability of the heating process are guaranteed. The setting of the heating component 8 works together with the filtering component 7, which can not only improve the air quality, but also adjust the air temperature, providing users with a more comfortable environment experience.

[0035] In general, the support base 1, the housing 2, the control circuit board 3, the motor 4, the wind wheel 5, the wind chamber 6, the filter component 7 and the heating component 8 constitute a complete system of the filtering multi-sided air outlet fan through reasonable structural connection and electrical coordination. Through the dynamic regulation of the core components by the control circuit board 3, the fan can perform air purification, temperature regulation and multi-directional air outlet according to different environmental conditions. This design not only realizes multi-functional integration, but also significantly improves the performance and user experience of the fan.

[0036] In summary, the stable connection between the support base 1 and the housing 2 provides a reliable support foundation for the core components. The core part drives the wind wheel 5 through the motor 4, and combines with the air inlet 61 and the air guide cavity 62 located in the wind chamber 6 to form a through wind guide structure. The wind guide design inside the wind chamber 6 effectively converts the airflow in a single direction into a wind flow evenly distributed in multiple directions through the circumferential distribution of multiple air outlets 63, thereby meeting the air circulation needs of multiple regions; in order to improve the air quality, the device also introduces a filter component 7, which realizes real-time control through electrical connection with the control circuit board 3, and can efficiently filter particulate matter in the air and improve the indoor environmental quality. At the same time, in order to adapt to different seasons and temperature conditions, the device integrates a heating component 8 near the air outlet 63, and controls it through the control circuit board 3 to achieve precise adjustment of the outlet temperature, thereby taking into account the dual functions of air purification and temperature control. Such a design not only overcomes the limitations of the single-direction air outlet of traditional fans, but also improves the functional diversity of the equipment, and meets the comprehensive needs of users for multi-region ventilation, air purification and ambient temperature regulation.

[0037] Further, such as Figure 1 , Figure 3 and Figure 4 As shown, the casing 2 includes a first shell 21 and a second shell 22 that are detachably connected, the first shell 21 is connected to the motor 4, the second shell 22 is provided with a limiting groove 221 protruding in the direction close to the first shell 21, the limiting groove 221 is limitedly matched with the filter component 7, and a protective net 222 is provided on the bottom of the limiting groove 221.

[0038] To sum up, by the casing 2 including a detachably connected first shell 21 and a second shell 22, it is convenient for users to maintain and clean the inside of the fan, thereby improving the convenience of use of the equipment and extending the service life; by the limiting cooperation between the limiting groove 221 on the second shell 22 and the filter component 7, the filter component 7 can be firmly installed, thereby preventing the filter component 7 from loosening during operation and causing performance degradation; by providing a protective net 222 on the bottom of the limiting groove 221, it is possible to prevent external foreign matter from entering the interior of the fan, thereby protecting the internal components of the fan and improving the operating safety of the equipment.

[0039] Further, such as Figure 3 and Figure 4 As shown, the limiting groove 221 includes a first groove body 2211 and a second groove body 2212 arranged in sequence along the direction close to the first shell body 21, the filtering component 7 includes a HEPA net 71, and a first PCT heater 72 electrically connected to the control circuit board 3, the first PCT heater 72 and the HEPA net 71 are stacked on the second groove body 2212 in sequence, and are limited in position with the second groove body 2212, the HEPA net 71 is closely fitted with the protective net 222, and the first groove body 2211 is limited in position with an air inlet grille 23.

[0040] In this embodiment, the limiting groove 221 constructs a layered installation structure by sequentially arranging the first groove body 2211 and the second groove body 2212 in the direction close to the first shell 21. This design enables different components to be fixed in the first groove body 2211 and the second groove body 2212 according to functional requirements, thereby optimizing the installation order and operating performance of the components. The first groove body 2211 is connected to the air inlet grille 23 by limiting the matching method. The function of the air inlet grille 23 is to regulate and guide the entry path of external air, while blocking larger particles or foreign matter from entering the air chamber 6, thereby protecting the safe operation of the subsequent filter component 7 and other components. The limiting matching design of the air inlet grille 23 ensures the stability of its installation and avoids displacement or loosening during operation.

[0041] The second slot body 2212 is connected to the filter component 7 through a limit fit, which provides precise positioning and stable support for the installation of the filter component 7. The filter component 7 includes a HEPA net 71 and a first PCT heating element 72, which are stacked in sequence on the second slot body 2212. The HEPA net 71 is used as the main air filter component, which can efficiently intercept particulate matter, dust and impurities in the air and improve the air quality. The HEPA net 71 is fitted with the protective net 222. The function of the protective net 222 is to provide physical protection for the HEPA net 71 to prevent it from being damaged by external collision or friction during long-term use, thereby extending the service life of the HEPA net 71. This fitting design ensures that the filter component 7 can maintain high-efficiency filtering performance during normal operation, while reducing the risk of performance degradation due to external interference.

[0042] The first PCT heater 72 is located on the other side of the HEPA net 71 and is electrically connected to the control circuit board 3, and can preliminarily heat the air entering the air chamber 6 according to environmental requirements. The function of the first PCT heater 72 is not only to increase the temperature of the air, but also to optimize the operating environment of the HEPA net 71 by adjusting the temperature, for example, to avoid the reduction of filtration efficiency due to moisture condensation under low temperature conditions. Through this arrangement, the stacking layout of the first PCT heater 72 and the HEPA net 71 enables the filtering and heating functions to be integrated, and at the same time, its limiting matching structure with the second slot body 2212 ensures the stability of the overall component, avoiding the impact of vibration or airflow on operation.

[0043] The structure of the entire limit slot 221 forms an efficient multifunctional integrated layout through the layered design of the first slot body 2211 and the second slot body 2212, as well as the installation method of the filter component 7 and its limit fit. The air inlet grille 23, the HEPA net 71, the first PCT heater 72 and the protective net 222 cooperate with each other in this system to achieve the functions of air guidance, filtration, heating and protection. In terms of control logic, the control circuit board 3 can adjust the heating power of the first PCT heater 72 according to the real-time detected environmental parameters, thereby dynamically adjusting the temperature of the air and ensuring that the filter component 7 operates under optimal conditions. This design logic not only ensures the efficient operation of the equipment, but also improves the overall reliability and user experience.

[0044] To summarize, by means of the limiting groove 221 including the first groove body 2211 and the second groove body 2212 arranged in sequence along the direction close to the first shell body 21, it is possible to realize the partitioned installation of the filter component 7, improve the rationality of the layout of the components, and further optimize the filtering effect and installation convenience of the fan; by means of the stacking design of the filter component 7 including the HEPA net 71 and the first PCT heating element 72, it is possible to simultaneously realize air filtration and preliminary heating, thereby improving the air purification and temperature control efficiency; by means of the close coordination of the HEPA net 71 and the protective net 222, the HEPA net 71 can be effectively protected from external damage, thereby extending the service life of the filter component 7; by means of the limiting coordination of the first groove body 2211 with the air inlet grille 23, the air intake path can be standardized, thereby improving the filtering efficiency.

[0045] Further, such as Figure 4 As shown, the heating component 8 includes a limit frame 81, and a second PCT heating body 82 that is limited by the limit frame 81 and electrically connected to the control circuit board 3. The air inlet 61 is connected to one side of the limit frame 81, and the other side of the limit frame 81 is connected to an air guide plate 9. The side of the air guide plate 9 away from the limit frame 81 is connected to an air outlet grille 24. The casing 2 is provided with a snap-in through hole 25, and the snap-in through hole 25 is snap-fitted with the air outlet grille 24.

[0046] In this embodiment, the heating component 8 realizes the stable installation and positioning function of its internal core components through the limiting cooperation design of the limiting frame 81. The limiting frame 81 serves as the basic supporting structure of the heating component 8, and its function is to provide stable mechanical support. At the same time, through the limiting cooperation with the second PCT heating body 82, it provides reliable fixing conditions for the installation and operation of the heating body. The limiting cooperation between the second PCT heating body 82 and the limiting frame 81 ensures that the heating component will not be displaced due to airflow vibration or external interference during operation. At the same time, it is linked with the control circuit board 3 through electrical connection, and the heating power can be dynamically adjusted according to environmental requirements. As the core heating component, the second PCT heating body 82 has the main function of efficiently heating the airflow passing through the fan and providing the user with controllable warm air output.

[0047] One side of the limit frame 81 is connected to the air inlet 61. The logic of this connection design is to optimize the airflow entry path so that the outside air can directly enter the limit frame 81 after passing through the air inlet 61 and undergo a heating treatment. The other side of the limit frame 81 is connected to an air guide plate 9. The function of the air guide plate 9 is to guide the airflow after the heating treatment so that it flows to the air outlet grille 24 and is discharged in a reasonable direction, thereby ensuring the uniformity and circulation efficiency of the airflow. The side of the air guide plate 9 away from the limit frame 81 is connected to the air outlet grille 24. The logic of this structural layout is that through the transition effect of the air guide plate 9, the airflow can be fully evenly distributed when it reaches the air outlet grille 24, thereby avoiding the local area effect differences caused by uneven airflow in traditional fans.

[0048] The air outlet grille 24 is matched with the snap-in hole 25 on the housing 2 by snap-in connection. This connection design not only facilitates the installation and removal of the air outlet grille 24, but also ensures the sealing of the airflow channel during the operation of the fan, avoiding the leakage of unfiltered or heated airflow, which affects the overall effect. The air outlet grille 24 is the terminal component for the discharge of airflow. Its function is to regulate the output direction of the airflow, so that the airflow evenly guided by the air guide plate 9 can be discharged to the external space at a suitable angle and strength. The snap-in design of the snap-in hole 25 and the air outlet grille 24 not only improves the structural stability, but also facilitates the user to perform maintenance or cleaning operations in the later stage.

[0049] In terms of control logic, the control circuit board 3 realizes precise control of the heating process through electrical connection with the second PCT heating body 82. Specifically, when the outside temperature is low, the control circuit board 3 can increase the power output of the second PCT heating body 82, so that the airflow is quickly heated to the temperature set by the user when passing through the heating component; when the outside temperature is high or the user does not need the heating function, the control circuit board 3 can reduce the heating power or completely turn off the heating body, thereby saving energy and extending the service life of the component. In addition, the coordinated design of the air guide plate 9 and the air outlet grille 24 not only optimizes the path of the airflow, but also improves the overall fan experience by guiding the airflow. This close structural connection and dynamic control logic together constitute an efficient heating and air guide system, which meets the user's dual needs for air temperature control and uniform airflow distribution.

[0050] To summarize, by the design that the heating component 8 includes a limit frame 81 and a second PCT heating body 82, the heating component 8 can be stably installed and an efficient heating function can be achieved, thereby improving the fan's air outlet temperature control capability; by connecting the air inlet 61 to one side of the limit frame 81, the stability of the airflow before entering the heating component 8 can be ensured, thereby improving the heating efficiency; by connecting the air guide plate 9 to the other side of the limit frame 81, the heated airflow can be evenly guided, thereby achieving uniform air outlet in multiple directions; by connecting the air guide plate 9 to the side away from the limit frame 81, the air outlet grille 24 can be further optimized to further optimize the air outlet path, thereby improving the air flow rate and air flow effect; by connecting the snap-in through hole 25 on the casing 2 with the air outlet grille 24, the heating component and the air outlet component can be conveniently disassembled and assembled, thereby improving the maintenance efficiency of the equipment.

[0051] Further, such as Figure 4 As shown, the second PCT heating body 82 includes a heating body 821 that is limited by the limiting frame 81, and a connecting terminal 822 located on one side of the heating body 821. The limiting frame 81 is provided with a clearance groove 811, and the clearance groove 811 is in contact with the connecting terminal 822 so that the connecting terminal 822 passes through the limiting frame 81 and is electrically connected to the control circuit board 3.

[0052] In this embodiment, the second PCT heating body 82 is stably installed by limiting the position with the limiting frame 81, wherein the heating body 821, as the core functional component of the second PCT heating body 82, can realize direct heating treatment of the air. The installation of the heating body 821 depends on the supporting function of the limiting frame 81. The limiting frame 81 not only provides precise positioning for the heating body 821, but also ensures the stability of the heating body 821 during the operation of the fan through the limiting design. A connecting terminal 822 is provided on one side of the heating body 821. The function of the connecting terminal 822 is to realize the electrical connection between the heating body 821 and the control circuit board 3, so that the heating body 821 can receive the signal command from the control circuit board 3 and dynamically adjust the heating power according to environmental requirements.

[0053] The design of the limit frame 81 includes a clearance groove 811, which is matched with the connection terminal 822 to provide space support for the connection terminal 822 to pass through and connect electrically. The existence of the clearance groove 811 ensures that the connection terminal 822 can pass through the limit frame 81 smoothly, while avoiding deformation or damage of the connection terminal 822 due to insufficient space. Through the way of clearance, the connection terminal 822 can not only achieve electrical connection, but also maintain stable integrity with the heating body 821, thereby avoiding loosening or failure of the connection parts due to air flow vibration or heat changes during equipment operation. After the connection terminal 822 passes through the limit frame 81, it establishes an electrical connection with the control circuit board 3. The function of the control circuit board 3 is to adjust the working state of the second PCT heating body 82 according to the real-time detected environmental parameters, such as adjusting the heating power to adapt to different temperature control requirements.

[0054] The overall structure of the limit frame 81 not only provides a basis for the installation and positioning of the heating body 821, but also realizes the functional separation of electrical connection and mechanical installation through the design of the matching of the clearance groove 811 and the connection terminal 822. Through this separation design, it is ensured that the heating body 821 will not interfere with the electrical performance of the connection terminal 822 while providing high-temperature output, and at the same time, it also avoids the instability of the circuit board connection terminal 822 in a high-temperature environment. The reasonable arrangement of the clearance groove 811 optimizes the internal space utilization while also improving the compactness and layout rationality of the internal structure of the device.

[0055] In terms of control logic, the control circuit board 3 accurately controls the operation of the second PCT heating body 82 through the electrical connection established with the connection terminal 822. Specifically, the control circuit board 3 can adjust the output power of the heating body 821 in real time according to the temperature changes of the external environment, thereby realizing dynamic regulation of the air temperature. This control logic can not only ensure that the air temperature output by the fan is always within the range of user requirements, but also save energy while avoiding component damage or safety risks caused by overheating. Through the organic coordination of the limit frame 81, the heating body 821 and the connection terminal 822, the structure realizes the efficient integration of functional modules, laying a reliable foundation for the stable operation and multi-functional expansion of the fan.

[0056] To sum up, through the design of the second PCT heating body 82 including the heating body 821 and the connecting terminal 822, efficient electric energy conversion and stable heating can be achieved, thereby improving the temperature control performance of the fan; through the clearance groove 811 provided on the limit frame 81, the connecting terminal 822 can pass through the limit frame 81 and be electrically connected to the control circuit board 3, thereby ensuring the stability of the electrical connection, while optimizing the internal space layout, and further improving the operating safety and reliability of the heating component.

[0057] like Figure 5 As shown, a control method of a filtering multi-sided air outlet fan is applied to a filtering multi-sided air outlet fan, and the control method includes: S10, if it is detected that no established scene mode is currently matched, then obtaining inlet and outlet air environment data in real time, the inlet and outlet air environment data at least including particle concentration data and regional temperature data of each outlet air area; In this embodiment, real-time acquisition of inlet and outlet environmental data refers to collecting relevant environmental parameters of the air inlet 61 and the air outlet 63 respectively through multiple high-precision sensors installed inside the filter-type multi-sided air outlet fan. Specifically, the particle concentration data is collected in real time by the particle sensor to reflect the condition of air quality, such as the concentration changes of PM2.5, PM10 and other particles. These data can directly indicate the degree of pollution in the air. The regional temperature data of each outlet area is collected by the temperature sensors distributed in each outlet 63, which can accurately measure the temperature value of each outlet area to determine the uniformity and effectiveness of temperature control. These data are transmitted to the central processing unit in real time through the signal processing module of the control circuit board 3 for analysis and storage. For example, when the particle concentration sensor detects that the PM2.5 concentration at the air inlet 61 is 120 micrograms / cubic meter, and the outlet concentration is only 30 micrograms / cubic meter, it indicates that the purification efficiency of the filter component is high, but if it is detected that the temperature of some outlet areas is lower than 18°C, and the temperature of other areas is 22°C, it can be judged that the current temperature control function fails to achieve uniform distribution. This real-time data acquisition method can help the system fully understand the current operating environment of the fan and provide accurate basic data for subsequent control decisions. For example, in spring when the pollen concentration is high, by acquiring the particle concentration data in real time, the efficient purification mode can be activated, and the distribution of the air outlet temperature can be optimized by combining the temperature data of each area.

[0058] S20, judging whether to perform a corresponding temperature control operation according to the inlet and outlet air environment data; In this embodiment, judging whether to perform the corresponding temperature control operation according to the inlet and outlet air environment data means judging whether to start the air purification or temperature control function by analyzing the real-time collected particulate matter concentration data and regional temperature data, combined with the pre-set threshold conditions. The specific implementation method includes: when the particulate matter concentration data is higher than the set threshold (such as PM2.5 concentration exceeds 100 micrograms / cubic meter), the system will automatically trigger the air purification mode, adjust the wind speed to high, and start the filter component to enhance the purification effect; when it is detected that the temperature of some outlet areas does not reach the temperature control range set by the user (for example, 20°C to 24°C), the system will judge that it is necessary to perform regional temperature control operations, and adjust the output power of the heating component 8 or control the angle of the air guide plate 9 to ensure that the outlet air temperature of each area can reach the set range. For example, in winter, when the system detects that the air temperature at the air inlet is low (such as 10°C), and finds that the temperature of some outlet areas is only 15°C, the system will start the high-power mode of the heating component 8, and guide the hot air to the low-temperature area by controlling the air guide plate 9 to quickly increase the local temperature. This operating logic not only ensures the uniformity of indoor air temperature, but also avoids the regional temperature difference problem existing in the traditional fan temperature control process.

[0059] S30, recording the number of occurrences and occurrence conditions of the temperature control operation, and if the number of occurrences exceeds a determined number threshold, establishing a new scene mode based on the temperature control operation, and associating the new scene mode with a scene mapping relationship of the occurrence condition; In this embodiment, recording the number of occurrences and conditions of the temperature control operation means that the system records the temperature control operation and its triggering conditions each time through the storage module built into the control circuit board 3. Specifically, it includes the particle concentration data when the operation is triggered, the temperature data of each air outlet area, the time of operation execution, the duration of operation, etc. Each time the temperature control operation is triggered, the system will store these data as a structured record. For example, when the system detects that the temperature of a certain area is lower than 18°C ​​for many times and triggers the local heating operation, the system will record detailed information such as "the temperature of the area is low (lower than 18°C), the power of the heating component 8 is 60W, and the operation lasts for 5 minutes"; when the particle concentration exceeds 120 micrograms / cubic meter continuously and the air purification function is started many times, the system will record the operating conditions and execution times such as "particle concentration>120 micrograms / cubic meter, wind speed is set to high, and filter components are started". The recording of these data provides an important basis for the subsequent generation of scene modes. For example, when the system finds that the number of triggers of certain conditions exceeds the threshold (such as 5 times), a new scene mode will be generated based on these records. For example, in the operation of a certain household, if the system detects that the particle concentration exceeds the standard between 22:00 and 23:00 every night and triggers the air purification operation multiple times, the system can generate a "night air purification mode" and automatically switch to this mode under similar environmental conditions in the future.

[0060] S40, determining in real time whether the occurrence condition is met, if not, re-determining, and if so, executing a new scene mode according to the scene mapping relationship.

[0061] In this embodiment, real-time judgment of whether the occurrence condition is met means that the system continuously monitors the environmental parameters and compares the real-time data with the recorded trigger conditions to determine whether it is necessary to switch to the newly generated scene mode. For example, when the system detects that the current particle concentration or temperature data is consistent with the recorded trigger conditions, such as the PM2.5 concentration is 120 micrograms / cubic meter, or the temperature of some outlet areas is lower than 18°C, the system will determine that the conditions are met and immediately activate the corresponding scene mode; if the conditions are not met, such as the particle concentration is lower than 50 micrograms / cubic meter or the temperature of all outlet areas is within the normal range (such as 20°C to 24°C), the system will continue to monitor environmental changes until the conditions match. This real-time judgment logic ensures the accuracy and timeliness of the execution of the scene mode and avoids unnecessary function switching. For example, during the summer afternoon, if the system detects that the particle concentration exceeds the standard and the regional temperature distribution is uniform, it will activate the "High-efficiency Purification Mode". At night, when the particle concentration decreases and the temperature control demand decreases, it will exit the current mode and enter a low-power standby state, thereby achieving energy-saving and efficient intelligent control.

[0062] In summary, by detecting that any established scene mode is not currently matched, real-time judgment of the device's operating status can be achieved, thereby ensuring the dynamic adaptability of the control logic; by obtaining the inlet and outlet air environment data in real time, the particle concentration and regional temperature distribution can be grasped in real time, thereby providing an accurate basis for subsequent intelligent control; by judging whether to perform corresponding temperature control operations based on the inlet and outlet air environment data, it can ensure that the equipment is adjusted according to actual environmental requirements, thereby improving energy efficiency and user experience; by recording the number and conditions of temperature control operations, operating data can be accumulated and used for scene mode optimization, thereby improving the intelligence level of the fan; by establishing a new scene mode and associating the scene mapping relationship, self-learning and dynamic optimization of the device's operating logic can be achieved, thereby improving operating efficiency and user satisfaction.

[0063] In one embodiment, if Figure 6 As shown, in step S20, i.e., the step of determining whether to perform a corresponding temperature control operation according to the inlet and outlet air environment data, the temperature control operation includes an inlet air environment temperature control operation and a regional temperature control operation, and the step further includes: S201, performing corresponding air inlet environment temperature control operation according to the particle concentration data; In this embodiment, performing the corresponding air inlet environment temperature control operation according to the particle concentration data refers to collecting the concentration data of the particles (such as PM2.5 or PM10) in the air in real time through the particle concentration sensor installed at the fan air inlet 61, and comparing the data with the preset air quality threshold. If the particle concentration is detected to exceed the set range, for example, the PM2.5 concentration exceeds 100 micrograms / cubic meter, the system will automatically adjust the wind speed according to the concentration level and activate the working state of the filter component 7, while regulating the operating mode of the heating component 8 on the one hand, and regulating the operating state of the filter component 7, specifically the first PCT heating element 72 on the other hand; Specifically, when the particle concentration is high, the system may increase the wind speed to accelerate air circulation and enhance the purification effect of the filter component; when the particle concentration is low, the wind speed will automatically decrease to save energy and extend the service life of the device. For example, in a poorly ventilated indoor environment, the particle sensor detects that the PM2.5 concentration reaches 150 micrograms / cubic meter, the system will immediately start the high-efficiency filtration mode, adjust the wind speed to high, and turn off the heating component 8 to concentrate resources on purification until the particle concentration drops to a safe range; In addition, the quality of the filtration effect can be optimized by adjusting the temperature. The fundamental reason is that temperature changes can directly or indirectly affect the physical and chemical conditions in the filtration process, thereby improving the removal efficiency of particles or pollutants. First of all, the performance of the filter device (such as the HEPA net) is most stable and efficient within a specific temperature range. When the air temperature is too low, moisture may condense on the surface of the filter to form a water film. This phenomenon will cause the filter pores to be partially blocked, thereby reducing air circulation and weakening the ability to capture particles. By appropriately raising the air temperature, moisture condensation can be prevented, and the permeability of the filter material can be maintained, enabling it to efficiently intercept particles. Conversely, when the air temperature is too high, some filter materials (such as composite fiber filters) may reduce the filtration efficiency due to thermal expansion or changes in material properties. Therefore, appropriately lowering the air temperature in a high temperature environment can avoid the decline in material performance and ensure the filtration effect.

[0064] In addition, temperature regulation also has a significant effect on the flow state of particulate matter. Higher air temperatures will cause the particles in the airflow to move faster, increasing the probability of contact with the filter surface, thereby improving capture efficiency. In a low temperature environment, the movement of particles is relatively slow, which is not conducive to the interception of the filter. Therefore, the capture capacity of the filter can be optimized by increasing the temperature. In addition, during the filtration of gaseous pollutants (such as formaldehyde and volatile organic compounds), temperature regulation can also promote the volatilization or chemical adsorption of pollutant molecules. For example, under appropriate temperature conditions, activated carbon filter materials can more efficiently adsorb formaldehyde and other harmful gases, while too low a temperature may reduce its adsorption capacity. Therefore, for different types of pollutants, reasonable temperature regulation can significantly improve the filtration effect.

[0065] At the same time, temperature regulation can also indirectly improve the operating environment of the filter components. For example, the heating device in the filter system can keep the filter material dry under low temperature conditions to avoid mold growth and microbial contamination caused by moisture or water vapor. This temperature regulation measure can not only extend the service life of the filter material, but also maintain its long-term high-efficiency filtering ability. In addition, temperature regulation can also be used in conjunction with wind speed regulation. By controlling the synergistic effect of temperature and air flow speed, the flow rate and pressure distribution of the air flow when passing through the filter can be optimized, making it easier for particles to be captured and stay in the filter layer, rather than escaping or clogging the filter due to too fast or too slow air flow.

[0066] S202, determining the regional threshold interval of each air outlet area; In this embodiment, determining the regional threshold intervals of each air outlet area means allocating a corresponding temperature control target range to each air outlet area according to the temperature requirements set by the user and the changes in the ambient temperature. These regional threshold intervals can be customized by the user through the device interface, or they can be automatically calculated by the system according to the external environment. The role of the regional threshold interval is to define an allowable temperature range for each air outlet area. For example, the temperature control target of a certain area is 20°C to 24°C, and another area may be 22°C to 26°C to meet the comfort needs of users in different locations. The system collects real-time temperature data from different areas and compares it with the regional threshold interval to determine whether further temperature control operations are required. For example, in a large living room, the user can set the temperature threshold of the sofa area to 23°C to 25°C, and the area near the door to 21°C to 23°C. The system will adjust the temperature distribution of different air outlets 63 according to these settings to ensure that the temperature of all areas meets user needs.

[0067] S203, determine whether the regional temperature data falls within the corresponding regional threshold interval, and if so, re-judge; in this embodiment, judging whether the regional temperature data falls within the corresponding regional threshold interval refers to real-time monitoring of the temperature of each air outlet area by a temperature sensor installed at the air outlet 63, and comparing the collected data with the regional threshold interval set in the previous step. If the temperature data of a certain area falls within its set threshold range, the system will determine that the current regional temperature control has met the requirements, without the need to perform additional temperature control operations, and continue to monitor other areas or wait for environmental changes. For example, when the set threshold of an area is 22°C to 24°C, and the real-time monitored temperature is 23°C, the system determines that the temperature control state of the area is normal, and the device will maintain the current working mode while avoiding unnecessary energy waste, thereby improving the operating efficiency of the equipment.

[0068] S204: If not, execute the corresponding regional temperature control operation.

[0069] In this embodiment, if not, the corresponding regional temperature control operation is performed, which means that when the temperature data of a certain air outlet area does not fall into the threshold interval set by it, the system will automatically trigger the temperature control function, adjust the power of the heating component 8 of the corresponding air outlet 63, the angle of the air guide plate or the wind speed, and ensure that the temperature of the area is quickly restored to the set range. Specific operations include: increasing or decreasing the power of the heating component to directly change the air outlet temperature, or guiding the warm air from other areas into the target area by adjusting the angle of the air guide plate to achieve uniform temperature distribution. For example, when the target threshold of an area is 22°C to 24°C, but the real-time detection temperature is 20°C, the system will increase the power of the heating component 8 of the air outlet 63 of the area to the rated value, and at the same time reduce the heating power of other areas to quickly increase the temperature of the area. In this way, not only can the temperature control needs of each area be met, but also the differences in user experience caused by uneven temperature control can be avoided, thereby achieving efficient temperature management and comfortable environmental control.

[0070] In summary, by performing air inlet environment temperature control operations based on particulate matter concentration data, the temperature control strategy can be accurately adjusted according to air quality requirements, thereby improving the effects of air purification and temperature regulation; by determining the regional threshold intervals of each air outlet area, the target temperature control range of each area can be clarified, thereby achieving independent control of the zones; by judging whether the regional temperature data falls into the corresponding regional threshold interval, the temperature control strategy can be dynamically monitored and adjusted, thereby further optimizing the local temperature control effect.

[0071] In one embodiment, if Figure 7 As shown, in step S201, that is, the step of performing the corresponding air inlet environment temperature control operation according to the particle concentration data, the particle concentration data includes the particle concentration at the air inlet and the particle concentration at the air outlet, including: S2011, obtaining the particle concentration T1 at the air inlet and the particle concentration T2 at the air outlet in the same time period; In this embodiment, obtaining the inlet particle concentration T1 and the outlet particle concentration T2 in the same time period refers to collecting the concentration data of the particles in the air in real time through the particle sensors installed at the fan inlet 61 and the outlet 63. Among them, the inlet particle concentration T1 is used to reflect the unfiltered air quality status, such as the concentration of PM2.5 or PM10 in the air, and the outlet particle concentration T2 is used to evaluate the air quality level after filtration. By collecting the data of T1 and T2 in the same time period, the accuracy of the data comparison can be guaranteed and the error caused by the difference in sampling time can be avoided. For example, in an environment with severe air pollution, the PM2.5 concentration detected by the inlet particle sensor is 150 micrograms / cubic meter, while the PM2.5 concentration detected by the outlet particle sensor is 30 micrograms / cubic meter, which indicates that the filter component effectively removes most of the particles under the current working conditions, providing a data basis for the subsequent calculation of the filtration efficiency.

[0072] S2012, calculating the filtration efficiency data T0 according to the inlet particle concentration T1 and the outlet particle concentration T2, the calculation formula is:

[0073] In this embodiment, the filtration efficiency data T0 is calculated based on the inlet particle concentration T1 and the outlet particle concentration T2, which means that the collected T1 and T2 data are processed by a preset calculation formula to quantify the purification capacity of the filter component. The calculation formula of the filtration efficiency T0 is usually: Indicates the percentage of particulate matter removed by the filter component to the total amount of particulate matter at the air inlet. For example, when T1 is 150 μg / m3 and T2 is 30 μg / m3, the calculated filtration efficiency T0 is 80%, which indicates that the filter component can remove 80% of the particulate matter under the current operating state. Through this calculation, the system can evaluate the performance of the filter component in real time and provide a basis for subsequent adjustments. If the filtration efficiency T0 is lower than the preset performance threshold (for example, 60%), the system may increase the fan speed or prompt the user to clean the filter to restore the filtration effect; when T0 reaches a higher level, the system can reduce the wind speed to save energy and extend the service life of the filter component. For example, during a certain operation, if T0 gradually drops from 80% to 50%, the system can issue a maintenance reminder to prompt the user to replace the HEPA filter 71, thereby ensuring that the air quality always meets the usage requirements.

[0074] In summary, by obtaining the inlet particle concentration T and the outlet particle concentration T in the same time period, the difference in air quality between inlet and outlet can be accurately monitored, thereby providing basic data for the calculation of filtration efficiency; by calculating the filtration efficiency data T based on T and T, the performance of the filter component 7 can be evaluated in real time, thereby providing a scientific basis for the adjustment and maintenance of the equipment operating status.

[0075] In one embodiment, if Figure 8 As shown, in step S30, that is, the step of establishing a new scene mode based on the temperature control operation, it includes: S3011. Extract key data according to the operation record of the temperature control operation, where the key data includes execution parameters and execution effects; In this embodiment, extracting key data according to the operation record of the temperature control operation means that the system screens and extracts the core information related to the operation from the stored temperature control operation log. This information includes the triggering conditions of each temperature control operation, the specific execution parameters, the duration of the operation, and the final effect. The execution parameters in the key data specifically refer to the power setting value of the heating component, the wind speed level of the fan, the angle adjustment of the air guide plate 9, and the target temperature range, etc.; the execution effect reflects whether these parameter adjustments have achieved the expected temperature control target, such as whether the temperature of the target area has reached the set range, whether the concentration of particulate matter in the air has been effectively reduced, etc. For example, in a certain operation, the system recorded that the operation trigger condition was that the temperature of the target area was lower than 18°C, the execution parameters were that the power of the heating component was set to 80W, the wind speed level was adjusted to "medium", the angle of the air guide plate was adjusted to 20 degrees, the operation duration was 15 minutes, and the temperature of the target area was finally raised to 22°C. By extracting these data, the system can accurately analyze the effectiveness and efficiency of the operation and provide a scientific basis for the generation and optimization of scene modes.

[0076] S3012, determining the matching degree between the key data and each of the established scene modes and the matching threshold according to the key data; In this embodiment, according to the key data, determining the matching degree between each of the established scene modes and the matching threshold means that the system compares the currently extracted key data with the parameters of the existing scene modes one by one to evaluate the similarity between these data and each scene mode. The matching degree is calculated based on the similarity of parameters, the coincidence of execution effects, etc., for example, whether the currently executed heating power, wind speed level and target temperature are consistent with the parameter range of a scene mode. The matching degree is expressed as a percentage value, reflecting the degree of adaptation of the current operation to a scene mode; the matching threshold is a preset reference value used to determine whether the current operation can be directly classified into an existing mode. For example, assuming that there is a "winter heating mode" in the system, the parameter range is 50W to 100W for heating power and 20℃ to 25℃ for target temperature, and the record of the current operation shows that the heating power is 90W and the target temperature is 23℃, the matching degree may be calculated as 92%. The system compares this matching degree with the preset matching threshold (such as 90%). If the matching degree is higher than the threshold, it means that the current operation can be classified into the scene mode.

[0077] S3013, determining whether each of the matching degrees is greater than the matching threshold, and if so, adjusting the mode parameters of the corresponding established scene mode according to the key data; In this embodiment, it is determined whether each of the matching degrees is greater than the matching threshold. If so, the mode parameters of the corresponding established scene mode are adjusted according to the key data. This means that when the system detects that the matching degree of the current operation is higher than the matching threshold of a scene mode, the key parameters of the current operation will be included in the scene mode to expand the scope of application of the mode and improve its accuracy. Specifically, the system will dynamically optimize the parameter range of the established scene mode according to the execution parameters of the current operation. For example, the original parameter range of the "winter heating mode" is a heating power of 50W to 100W, and a target temperature range of 20℃ to 25℃. If the heating power of the current operation is 90W and the target temperature is 26℃, the system will expand the target temperature range to 20℃ to 26℃, thereby covering more actual operation scenarios. This adjustment not only makes the existing scene mode more flexible, but also reduces unnecessary mode switching operations caused by insufficient matching. For example, during a certain operation, if it is found that a certain area needs to frequently raise the temperature to 26°C, but the original target temperature range of the more matching "winter heating mode" only covers 20°C to 25°C, the system will adjust the mode parameters to include this temperature in the existing mode range, avoid generating a new mode, and thus improve efficiency.

[0078] S3014: If not, determine the mode parameters and mode type according to the execution parameters, and determine the corresponding scene priority according to the execution effect.

[0079] In this embodiment, if not, the mode parameters and mode types are determined according to the execution parameters, and the corresponding scene priority is determined according to the execution effect, which means that when the system detects that the matching degree of the current operation is lower than the matching threshold of all established scene modes, a new scene mode will be automatically generated. The generation process of the new mode includes two key parts: determining the mode parameters and mode types, and assigning scene priorities. The determination of the mode parameters is based on the execution parameters of the current operation, such as the heating component power is 80W, the wind speed level is "high", the target temperature is 22℃ to 24℃, the wind deflector angle is 30 degrees, and the operation duration is 10 minutes. These parameters will be directly used as the initial configuration of the new mode. The mode type is automatically classified according to the functional characteristics of the current operation. For example, if the operation is mainly based on raising the air temperature, the new mode type may be "regional heating mode"; if the operation is based on particulate matter concentration adjustment, the new mode type may be "air purification priority mode". The scene priority is determined based on the execution effect of the current operation and the frequency of user needs. For example, if the current operation can quickly increase the temperature of the target area from 18°C ​​to 24°C, the effect is significant and the trigger frequency is high, the system will assign a higher priority to this mode to ensure that it can be activated first under similar environmental conditions in the future. For example, in a home environment, the system detects that the temperature of the living room area needs to be increased from 20°C to 25°C between 22:00 and 23:00 every night, and the current operation matching degree is lower than the established mode threshold. The system will generate a "nighttime living room heating mode" with a heating power range of 70W to 100W and a target temperature range of 24°C to 26°C, and set its priority to "high" to ensure that it can respond quickly and activate the mode under the same conditions in the future. Through this process, the generation of new scene modes is both scientific and efficient, and can meet the diverse needs of users, while continuously improving the intelligence level of the system.

[0080] In summary, by extracting key data based on the operation records of temperature control operations, it is possible to capture the execution parameters and execution effects during the operation process, thereby providing data support for the optimization of scene modes; by determining the degree of match with established scene modes, it is possible to dynamically evaluate the applicability of existing modes, thereby avoiding mode redundancy or mismatch problems; by adjusting the mode parameters of established scene modes, it is possible to optimize the operating logic of existing modes, thereby improving the mode execution effect; by determining the scene priority based on the execution effect, it is possible to reasonably allocate operating resources, thereby improving the overall efficiency of the equipment.

[0081] In one embodiment, if Fig. 9 As shown, in step S30, that is, the step of associating the new scene mode with the scene mapping relationship of the occurrence condition, the scene mapping relationship includes a first mapping relationship and a second mapping relationship, and the step includes: S3021, classifying each occurrence item included in the occurrence condition to generate one or more classification packages; In this embodiment, the occurrence conditions are classified to generate one or more classification packages, which means that the system analyzes the recorded occurrence conditions, classifies the conditions according to their attributes and logical relationships, and classifies the conditions with similar trigger mechanisms or targets into the same classification package. For example, the occurrence conditions may include multiple items such as particulate matter concentration exceeding a certain threshold, regional temperature below a set interval, and a high frequency of triggering within a specific time period. The system will analyze and integrate these items through rules or algorithms, for example, "particulate matter concentration greater than 100 micrograms / cubic meter" and "PM2.5 concentration significantly increased" are classified into the "air quality related" classification package, and "target temperature below 18°C" and "temperature difference in a certain area greater than 5°C" are classified into the "temperature control adjustment related" classification package. The purpose of this classification is to simplify the management of conditions so that complex condition combinations can be structured, thereby providing a clear logical basis for subsequent scene mode mapping. For example, in a certain operation record, the system detected that air quality conditions and temperature control conditions occurred simultaneously multiple times, and classified them into the "air purification" package and the "regional temperature control" package respectively, preparing for the subsequent establishment of mapping relationships.

[0082] S3022. If the classification package is one, then the new scene mode is associated with the first mapping relationship of the classification package; in this embodiment, if the classification package is one, then the first mapping relationship of the new scene mode and the classification package is associated, which means that when the system analysis results show that all occurrence conditions are classified into the same classification package, a simple mapping relationship will be directly established between the newly generated scene mode and the classification package. The characteristic of this first mapping relationship is that the mapping logic is relatively simple, and the scene mode only needs to consider whether the conditions in the classification package are met to be triggered, without further distinguishing the priority. For example, when the system detects that all occurrence conditions belong to the "air quality related" package, including "particulate matter concentration is higher than 120 micrograms / cubic meter" and "PM2.5 continues to rise for more than 10 minutes", the system will generate an "air purification mode" and directly associate it with the classification package. In this way, when the air quality condition is detected to be triggered again in the future, the system can quickly match the "air purification mode", so as to adjust the parameters such as wind speed and filtration intensity in time without complex calculations. For example, in a confined space, when the particle concentration continues to exceed the standard, the system will immediately activate the air purification mode based on the first mapping relationship to ensure indoor air quality.

[0083] S3023: If there are multiple classification packages, assign corresponding conditional priorities to each of the classification packages based on the established priority allocation model, and associate a second mapping relationship between a new scene mode and the classification package based on the conditional priorities.

[0084] In this embodiment, if there are multiple classification packages, then based on the established priority allocation model, the corresponding condition priority is assigned to each of the classification packages, and based on the condition priority, the second mapping relationship between the new scene mode and the classification package is associated, which means that when the occurrence condition is classified into multiple classification packages, the system will set the priority for each classification package according to the priority allocation model, and thereby establish a complex scene mode mapping relationship. The priority allocation model can be based on factors such as the triggering frequency of the condition, the importance to user needs, and the resource consumption when executing the scene mode. For example, the priority of the "temperature control adjustment related" condition may be higher than the "air quality related" condition because temperature control directly affects the user's somatosensory comfort. In this case, the new scene mode will first meet the conditions of the higher priority classification package, and then consider the lower priority conditions. For example, the system generates a "night purification and heating mode", and its associated two classification packages are "temperature control adjustment related" and "air quality related". The system will give priority to the regional temperature control conditions to ensure that the target temperature reaches the set range, and then adjust the filter components and wind speed according to the air quality. In actual applications, if the temperature in a certain area is detected to be lower than 18°C ​​and the particle concentration is higher than 100 micrograms per cubic meter, the system will prioritize increasing the heating power to restore the temperature to the target range, and then adjust the wind speed according to the air quality conditions. This second mapping relationship based on priority makes the execution of scene modes more targeted and hierarchical, thereby achieving efficient intelligent control under complex conditions.

[0085] To sum up, by classifying the occurrence items contained in the occurrence conditions, complex conditions can be simplified and structured, thereby improving the processing efficiency of the mapping relationship; by associating the new scene mode with the first mapping relationship of the classification package, a rapid response to a single condition can be achieved, thereby improving the mode switching speed; by assigning condition priorities to the classification package based on the priority allocation model, a multi-condition environment can be reasonably allocated, thereby avoiding resource conflicts and improving operational stability; by associating the new scene mode with the second mapping relationship of the classification package, intelligent switching of multiple scene modes can be achieved in a multi-condition environment, thereby improving the intelligence level and adaptability of the equipment.
