If the filter component and the heating component are installed at the same time, the system starts the fan component with a fourth power to meet the needs of filtering and heating at the same time, ensuring the comfort and cleanliness of the indoor air. When the system receives purification signals and heating signals at the same time, if both the filter component and the heating component are installed, the system will dynamically adjust the working power of the heating component and the fan component according to the air filtration requirements and the heating requirements. This can effectively regulate the indoor temperature and provide a comfortable living environment while ensuring air quality.

[0022] In one embodiment, the specific steps of step S4 are as follows: S41, matching the working power of the fan assembly according to the purification level of the purification signal; S42, matching the initial heating power of the heating assembly according to the working power of the fan assembly and the heating level in step S41; S43, collecting the temperature value at the air outlet in real time, adjusting the heating power of the heating assembly according to the temperature at the air outlet and the air volume corresponding to the purification level, so that the heating effect of the warm air finally output matches the heating level. By matching the working power of the fan assembly according to the purification level of the purification signal, the system can ensure that appropriate air flow is provided under different purification requirements. This matching can improve the purification efficiency, provide strong wind when efficient purification is required, and save energy when the demand is low. After determining the working power of the fan assembly, the system will match the initial heating power of the heating assembly in combination with the heating level. This step ensures that when heating starts, appropriate heat can be provided according to the air flow situation, improve the heating efficiency, and avoid insufficient or excessive initial heating. By monitoring the temperature value at the air outlet in real time, the heating power of the heating assembly is dynamically adjusted. This real-time adjustment can continuously optimize the temperature of the warm air according to the actual situation, so that the output warm air effect always matches the set heating level. By combining the outlet temperature and the air volume corresponding to the purification level, the system can provide a comfortable temperature while ensuring air quality. This design ensures that the system can provide the best air treatment effect under different working environments and requirements.

[0023] In one of the embodiments, the specific steps of step S43 are as follows: S431, pre-set the corresponding air volume for each purification level, and match the corresponding air volume according to the purification level; S432, collect the actual temperature value at the air outlet, obtain the target temperature value required for the current heating level according to the air volume corresponding to the heating level and the purification level, and calculate the temperature difference between the target temperature value and the actual temperature value; S433, adjust the heating power of the heating component according to the temperature difference and the air volume corresponding to the purification level, so that the heating effect matches the heating level, and the adjusted heating power is expressed as: , where Q a Indicates the adjusted heating power, Q i is the initial heating power, k is the adjustment coefficient, which is used to convert the temperature difference and air volume into power adjustment, T t is the target temperature value, T a is the actual temperature value, V aThe air volume corresponding to the purification level. By pre-setting the air volume corresponding to each purification level, and automatically matching the corresponding air volume according to the current purification level. This ensures that under different purification needs, the air volume can always meet the preset standards, thereby achieving the best purification effect. Monitor the actual temperature at the air outlet in real time, and calculate the required target temperature value based on the heating level and the corresponding air volume. By comparing the target temperature value and the actual temperature value, the system can accurately calculate the current temperature difference and provide a basis for subsequent heating power adjustment. Adjusting the heating power of the heating component according to the temperature difference and the air volume corresponding to the purification level can accurately and dynamically adjust the power of the heating component according to the temperature difference and the air volume, ensuring that the output warm air effect matches the set heating level.

If the filter component 3 or the heating component 5 is not installed, a third prompt message is issued.

[0068] The second aspect of the present application discloses a purification method, which ensures that the system can monitor the installation status of key components in real time by detecting the installation status of the filter component 3 and the heating component 5. By displaying the installation status, the user can clearly understand the current configuration of the device and ensure the effectiveness and safety of the device operation. When the system receives a purification signal, it will match the corresponding working power according to the preset purification level. If only the filter component 3 is installed, the system starts the fan component 2 with the first power, which can effectively ensure that energy is saved and a suitable air flow effect is provided when only filtering is required. If the filter component 3 and the heating component 5 are installed at the same time, the system starts the fan component 2 according to the second power to meet higher purification requirements and possible heating requirements. When the system receives a warm air signal, it will match the corresponding working power according to the heating level. If only the heating component 5 is installed, the system starts the fan component 2 with the third power to provide an appropriate warm air effect.

When the system receives the purification signal and the warm air signal at the same time, if the filter component 3 and the heating component 5 are installed at the same time, the system will dynamically adjust the working power of the heating component 5 and the fan component 2 according to the air filtration demand and the warm air demand. This can effectively adjust the indoor temperature and provide a comfortable living environment while ensuring the air quality. If the filter component 3 or the heating component 5 is not installed, the system will issue a corresponding prompt message to remind the user to perform necessary configuration or maintenance to ensure the normal operation and efficiency of the equipment. The purification method can accurately control the working state of the equipment according to different signals and installation configurations through an intelligent response mechanism, thereby achieving energy-saving, high efficiency and comfort. This reasonable design not only improves the practicality and user experience of the equipment, but also helps to maintain the performance and stability of the equipment in the long term.

By matching the working power of the fan assembly 2 according to the purification level of the purification signal, the system can ensure that appropriate air flow is provided under different purification requirements. This matching can improve the purification efficiency, provide strong wind when efficient purification is required, and save energy when the demand is low. After determining the working power of the fan assembly 2, the system will match the initial heating power of the heating assembly 5 in combination with the heating level. This step ensures that when heating starts, appropriate heat can be provided according to the air flow situation, improve the heating efficiency, and avoid insufficient or excessive initial heating. By real-time monitoring of the temperature value at the air outlet 103, the heating power of the heating component 5 is dynamically adjusted. This real-time adjustment can continuously optimize the temperature of the warm air according to the actual situation, so that the output warm air effect always matches the set heating level. By combining the air outlet temperature and the air volume corresponding to the purification level, the system can provide a comfortable temperature while ensuring air quality. This design ensures that the system can provide the best air treatment effect under different working environments and requirements.

[0070] like Fig. 20 As shown, in addition to the features of the above-mentioned embodiment, the present embodiment further defines: the specific steps of step S43 are as follows: S431, pre-set the corresponding air volume for each purification level, and match the corresponding air volume according to the purification level; S432, collect the actual temperature value at the air outlet 103, obtain the target temperature value required for the current heating level according to the air volume corresponding to the heating level and the purification level, and calculate the temperature difference between the target temperature value and the actual temperature value; S433, adjust the heating power of the heating component 5 according to the temperature difference and the air volume corresponding to the purification level, so that the heating effect matches the heating level, and the adjusted heating power is expressed as: , where Q a Indicates the adjusted heating power, Q i is the initial heating power, k is the adjustment coefficient, which is used to convert the temperature difference and air volume into power adjustment, T t is the target temperature value, T a is the actual temperature value, V aThe air volume corresponding to the purification level. The air volume corresponding to each purification level is pre-set, and the corresponding air volume is automatically matched according to the current purification level. This ensures that the air volume can always meet the preset standards under different purification requirements, thereby achieving the best purification effect. The actual temperature at the air outlet 103 is monitored in real time, and the required target temperature value is calculated according to the heating level and the corresponding air volume. By comparing the target temperature value and the actual temperature value, the system can accurately calculate the current temperature difference and provide a basis for subsequent heating power adjustment. Adjusting the heating power of the heating component 5 according to the temperature difference and the air volume corresponding to the purification level can accurately and dynamically adjust the power of the heating component according to the temperature difference and the air volume, ensuring that the output warm air effect matches the set heating level.
