Description

Technical Field

[0001] The present invention relates to the technical field of data processing, and in particular to a method, device, equipment, medium and flue control system for determining the life of a filter. Background Art

[0002] With the development of urbanization, there are more and more high-rise buildings. According to national regulations, high-rise buildings must have public flues for users to exhaust smoke, but the problem that comes with it is that public flues are often congested. The most intuitive feeling is that the indoor range hoods (hereinafter referred to as indoor units) have poor exhaust effects. Therefore, some high-rise buildings will install a large fan (hereinafter referred to as outdoor units) on the top floor to help the indoor units extract and exhaust oil smoke. Usually, the outdoor unit needs to be equipped with a filter. The existing methods for determining the life of the outdoor unit filter in the public flue are mainly based on the calculation method of cumulative operating time and fixed operating time. Among them, the cumulative operating time filter life determination method is to determine the service life of the outdoor unit filter by accumulating the operating time of the outdoor unit, and to give an early warning when the filter operating time is reached; the fixed time filter life determination method is to start counting from the time the outdoor unit filter is installed (regardless of whether the outdoor unit is turned on), and give an early warning when the time reaches the preset time.

[0003] The shortcomings of existing filter life determination methods are as follows:

[0004] 1. Using the fixed-time filter life determination method, when no user uses the indoor unit for a long time or only a very small number of indoor units are turned on, the outdoor unit filter reaches the pre-set service life after a period of time and needs to be replaced; however, the actual life of the filter has not been reached, resulting in a waste of resources, increased user costs, and increased workload for service personnel.

[0005] 2. Use the cumulative running time method to determine the filter life. When a large number of indoor units are used at the same time for a long time (for example, 50 indoor units are turned on at the same time), the outdoor unit filter needs to filter more flue pollution than designed. At this time, the filter's pre-set life has not been reached, but the filter's actual life will be reached in advance. The filter cannot filter the oil smoke, which affects the environment and the flue smoke exhaust effect. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects that the existing method for determining the life of the filter cannot accurately predict the actual service life of the filter, resulting in the situation that the actual service life is greater than or less than the preset service life; when the actual service life is less than the preset service life, it will cause waste of resources, increased user usage costs and increased workload of service personnel; when the actual service life is greater than the preset service life, it will cause the filter to fail to filter the oil smoke in time, causing impact on the environment and affecting the smoke exhaust effect of the flue, and provide a method for determining the life of the filter, a device, equipment, medium and flue control system.

[0007] The present invention solves the above technical problems through the following technical solutions:

[0008] In a first aspect, a method for determining the life of a filter is provided, wherein the filter is provided at the air outlet of a common flue, and the common flue is connected to the indoor unit on each floor. The method comprises:

[0009] Obtaining a filter air volume influencing parameter, wherein the filter air volume influencing parameter includes at least one of a flue opening area, the number of indoor units turned on, the turn-on time, the floor information, and the gear information;

[0010] Obtaining the actual filtered air volume of the filter based on the filter air volume influencing parameter;

[0011] Obtaining the total air volume that can be filtered by the filter;

[0012] Calculating the remaining filtered air volume of the filter according to the actual filtered air volume and the total filterable air volume;

[0013] The remaining filtered air volume is positively correlated with the remaining life of the filter.

[0014] The present invention obtains different filter air volume influencing parameters, calculates the actual filtration air volume of the filter corresponding to the different filter air volume influencing parameters, obtains the total filterable air volume of the filter, calculates the residual filtration air volume of the filter according to the actual filtration air volume of the filter and the total filterable air volume of the filter, characterizes the remaining life of the filter according to the residual filtration air volume of the filter, and accurately determines the remaining life of the filter; improves the calculation accuracy of the actual filtration air volume of the filter by designing an optimization scheme, and then improves the accuracy of obtaining the residual filtration air volume that characterizes the remaining life of the filter, ensures the maximization of the service life of the filter, improves the utilization rate of the filter, effectively avoids the waste of resources caused by the actual service life of the filter not being reached, reduces user usage costs, reduces the workload of service personnel, improves the smoke exhaust effect of the flue, and at the same time avoids the environmental pollution caused by the filter's actual service life being reached early and the filter being unable to efficiently filter oil smoke.

[0015] Preferably, the filter air volume influencing parameters include the opening quantity and the opening time;

[0016] The step of obtaining the actual filtered air volume of the filter based on the filter air volume influencing parameter includes:

[0017] Obtaining actual output air volume information corresponding to each indoor unit after it is turned on;

[0018] The actual filtered air volume of the filter is calculated according to the number of opened units, the opening time, and the actual output air volume information of each opened indoor unit.

[0019] The filter air volume influencing parameters of the present invention include the number of indoor units turned on and the start-up time. By obtaining the actual output air volume information corresponding to each indoor unit after it is turned on, the actual filtering air volume of the filter is calculated according to the number of indoor units turned on, the start-up time and the actual output air volume information of each turned-on indoor unit. This solves the problem of data calculation of the actual filtering air volume of the filter when multiple indoor units are turned on at the same time, improves the calculation accuracy of the actual filtering air volume of the filter, and further improves the accuracy of obtaining the remaining filtering air volume that characterizes the remaining life of the filter, thereby ensuring that the service life of the filter is maximized and improving the utilization rate of the filter.

[0024] The actual filtered air volume of the filter is calculated based on the first air volume information of the indoor unit turned on on each floor and the corresponding turning-on time.

[0025] The filter air volume influencing parameters of the present invention include the number of indoor units turned on, the turning-on time and the floor information of the indoor units. By obtaining the actual air volume information corresponding to the floor information of the turned-on indoor units, when multiple indoor units are turned on at the same time, the first air volume information output by the indoor units on each floor at the air outlet of the public flue is calculated based on the actual air volume information of different floors. The actual filtered air volume of the filter is calculated based on the first air volume information and the corresponding turning-on time of the indoor units turned on on each floor. This solves the problem of data calculation of the actual filtered air volume of the filter when multiple indoor units on different floors are turned on at the same time, and further determines the remaining life of the filter in this case. The remaining life of the filter is accurately determined, the service life of the filter is maximized, and the utilization rate of the filter is improved.

[0026] Preferably, the filter air volume influencing parameter further includes the floor information and the gear information;

[0027] The step of calculating the actual filtered air volume based on the filter air volume influencing parameter comprises:

[0028] Obtaining the actual gear parameter of the indoor unit of the floor information;

[0030] Based on the reference gear parameter, the reference air volume and the actual gear parameter, calculating the second air volume information output by each turned-on indoor unit at the air outlet of the common flue;

[0031] The actual filtered air volume of the filter is calculated based on the second air volume information of the indoor unit turned on on each floor and the corresponding turning-on time.

[0032] The filter air volume influencing parameters of the present invention include the number of indoor units turned on, the turning-on time, the floor information and the gear information of the indoor units. By obtaining the actual gear parameters of the indoor units of the floor information where the indoor units are located, the reference gear parameters and the reference air volume corresponding to the reference gear parameters, the second air volume information output by each turned-on indoor unit at the air outlet of the public flue is calculated. Based on the second air volume information and the corresponding turning-on time of the indoor units turned on on each floor, the actual filtered air volume of the filter is calculated, which solves the problem of data calculation of the actual filtered air volume of the filter when multiple indoor units on different floors are turned on at the same time and the gears of the indoor units are different, improves the calculation accuracy of the actual filtered air volume of the filter, and further improves the accuracy of obtaining the remaining filtered air volume that characterizes the remaining life of the filter, thereby ensuring that the service life of the filter is maximized and improving the utilization rate of the filter.

[0033] Preferably, the filter air volume influencing parameter also includes the flue opening area;

[0035] Obtaining the filtration area of ​​the filter;

[0036] Calculating the ratio of the flue outlet area to the filter area;

[0037] Update the new filterable total air volume according to the ratio;

[0038] The step of calculating the remaining filtered air volume of the filter according to the actual filtered air volume and the total filterable air volume includes:

[0039] The difference between the updated total filterable air volume and the actual filtered air volume is calculated, and the difference is used as the remaining filtered air volume.

[0040] The filter air volume influencing parameters of the present invention include the flue port area, the number of indoor units turned on, the turning-on time, the floor information and the gear information. By obtaining the filtering area of ​​the filter, the ratio of the flue port area to the filtering area is calculated, and the total filterable air volume of the new filter is updated according to the ratio. The difference between the updated total filterable air volume and the actual filtered air volume of the filter is calculated, and the difference is used as the remaining filtered air volume of the filter. This solves the problem of calculating the actual filtered air volume of the filter when the flue port areas are different, when multiple indoor units on different floors are turned on at the same time and when the indoor units are in different gears, and updates the remaining filtered air volume of the filter. The total filtered air volume is then calculated, and the remaining life of the filter in this case is determined by the difference between the total filterable air volume of the updated filter and the actual filtered air volume of the filter. The multiple dimensional parameters that can affect the actual filtered air volume of the filter are comprehensively considered to finally calculate the actual filtered air volume, thereby further improving the calculation accuracy of the actual filtered air volume of the filter, and then improving the accuracy of obtaining the remaining filtered air volume that characterizes the remaining life of the filter, thereby maximizing the service life of the filter, improving the utilization rate of the filter, reducing user usage costs, reducing the workload of service personnel, improving the flue smoke exhaust effect, and being beneficial to protecting the environment.

[0081] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0082] Example 1

[0083] Figure 1 1 is a flow chart of a method for determining the life of a filter screen provided in Example 1 of the present invention, the method comprising the following steps:

[0084] Step 101: Obtain filter air volume influencing parameters.

[0085] In this embodiment, the parameters affecting the filter air volume include but are not limited to the flue outlet area, the number of indoor units turned on, the turning-on time, the floor information and the gear information.

[0086] The opening time and number of times the indoor unit is turned on will affect the actual filtering air volume of the filter; the air volume produced by indoor units on different floors in the flue is also different. Because there is air leakage in the public flue, the air volume produced by the indoor range hoods on each floor and the air volume reaching the public flue outlet are different, that is, the floor information where the indoor unit is located will affect the actual filtering air volume of the filter; the indoor unit will also produce different air volumes at different gears, that is, the gear information of the indoor unit will affect the actual filtering air volume of the filter; the outdoor unit is installed in different household types, and the flue outlets also have different sizes, and the flue outlets have different areas. The different flue outlet areas have different cross-sectional areas of the filter that actually filter the oil smoke, that is, the flue outlet area will affect the total filterable air volume of the filter, and then affect the remaining filtering air volume of the filter.

[0087] Step 102: Obtain the actual filtered air volume of the filter based on the filter air volume influencing parameter.

[0088] Different filter air volume influencing parameters correspond to different actual filtration air volumes of the filters and the total filterable air volumes of the filters.

[0089] Among them, the number of indoor units turned on, the time of turning on, the floor information, and the gear information will affect the actual filtering air volume of the filter. The actual filtering air volume of the corresponding filter is calculated according to different filter air volume influencing parameters.

[0090] Step 103: Obtain the total filterable air volume of the filter.

[0091] Among them, when the filter influencing parameters include the flue opening area, it will affect the total filterable air volume of the filter.

[0092] Step 104: Calculate the remaining filtration air volume of the filter according to the actual filtration air volume of the filter and the total filtration air volume of the filter.

[0093] Among them, the size of the residual filtering air volume of the filter is positively correlated with the remaining life of the filter.

[0094] This embodiment obtains the filter air volume influencing parameters, obtains the actual filtration air volume of the filter and the total filterable air volume of the filter under different filter air volume influencing parameters, and then calculates the residual filtration air volume of the filter. When the size of the residual filtration air volume is positively correlated with the remaining life of the filter, by improving the calculation accuracy of the actual filtration air volume of the filter, the accuracy of obtaining the residual filtration air volume that characterizes the remaining life of the filter is improved, thereby ensuring the maximization of the service life of the filter, improving the utilization rate of the filter, and effectively avoiding the waste of resources caused by the actual life of the filter not being reached, reducing user usage costs, reducing the workload of service personnel, and the environmental pollution caused by the early reaching of the actual life of the filter, thereby improving the flue smoke exhaust effect and being beneficial to protecting the environment.

[0095] Example 2

[0096] The calculation method of the filter screen life of this embodiment is a further improvement of the embodiment 1. Specifically:

[0097] Figure 2 This is a method flow chart corresponding to step 102 provided in Example 2 of the present invention; in step 102, the step of obtaining the actual filtered air volume of the filter based on the filter air volume influencing parameter includes:

[0098] Step 10211: Obtain the actual output air volume information corresponding to each indoor unit after it is turned on.

[0099] In this embodiment, the filter air volume influencing parameters include the number of indoor units turned on and the on-time. The on-time and the number of indoor units turned on will affect the actual filtered air volume of the filter.

[0100] Step 10212: Calculate the actual filtered air volume of the filter based on the number of indoor units turned on, the turn-on time, and the actual output air volume information of each turned-on indoor unit.

[0101] In this embodiment, when the number of indoor units turned on is N, the turn-on time is T, the actual output air volume information corresponding to each indoor unit turned on is Q, the total air volume that can be filtered by the filter is Vall, the remaining filtered air volume of the filter is Vrem, and the actual filtered air volume of the filter is Vact, then the actual filtered air volume of the filter is

[0102] The residual filtration air volume Vrem of the filter is calculated based on the actual filtration air volume Vact of the filter and the total filtration air volume Vall of the filter.

[0103] This embodiment calculates the actual filtering air volume of the filter by obtaining the number and opening time of the indoor units, thereby solving the data calculation of the actual filtering air volume of the filter when multiple indoor units are turned on at the same time, and then determines the remaining life of the filter in this situation, thereby improving the calculation accuracy of the actual filtering air volume of the filter, and then improving the accuracy of obtaining the remaining filtering air volume that represents the remaining life of the filter, ensuring the maximization of the service life of the filter, improving the utilization rate of the filter, and effectively avoiding the waste of resources caused by the actual life of the filter not being reached, reducing user usage costs, reducing the workload of service personnel, and the environmental pollution caused by the early expiration of the actual life of the filter.

[0104] Example 3

[0105] The calculation method of the filter screen life of this embodiment is a further improvement of the embodiment 1. Specifically:

[0106] Figure 3 This is a method flow chart corresponding to step 102 provided in Example 3 of the present invention; in step 102, the step of obtaining the actual filtered air volume of the filter based on the filter air volume influencing parameter includes:

[0107] Step 10221: Obtain the actual air volume information corresponding to the floor information where the indoor unit is turned on.

[0108] In this embodiment, the parameters influencing the filter air volume include the number of indoor units active, their activation time, and the floor they are located on. The air volume produced by indoor units on different floors in the common flue varies. Because common flues can leak, the air volume produced by the indoor range hoods on each floor, and the air volume reaching the common flue outlet, varies. Therefore, the floor location, number of indoor units active, and activation time all affect the actual filtered air volume.

[0109] In this embodiment, the indoor unit on the lowest floor (lth floor) is turned on, and the air volume at the flue outlet of the outdoor unit is measured as Ql; the indoor unit on the highest floor (hth floor) is turned on, and the air volume at the flue outlet of the outdoor unit is measured as Qh. The actual air volume information corresponding to the floor information where the indoor unit is turned on is Qh-Ql.

[0110] Step 10222: When multiple indoor units are turned on at the same time, based on the actual air volume information of different floors, calculate the first air volume information output by the indoor units on each floor at the air outlet of the public flue.

[0111] In this embodiment, n is defined to indicate that the floor where the indoor unit is located is the nth floor, h is defined to indicate that there are h floors where the indoor units are located, and the first air volume information outputted by the indoor unit on the nth floor at the air outlet of the public flue is Qn;

[0112] When the indoor unit is located on the 1st floor, based on the actual air volume information of different floors, the first air volume information output by the indoor unit on the 1st floor at the air outlet of the common flue is equal to the actual air volume information Q1 corresponding to the floor information of the indoor unit.

[0113] When the indoor unit is located on the nth floor, n is greater than or equal to 2 and h is greater than or equal to 2, based on the actual air volume information of different floors, the first air volume information output by the indoor unit on each floor at the air outlet of the public flue is calculated to be Qn, then Qn = (Qh-Ql) / (hl)*(nl).

[0114] Technical personnel in this field can obtain the actual air volume information corresponding to the floor information where the indoor unit is turned on according to actual needs. For example, when the indoor unit on the second lowest floor (2nd floor) is turned on, the air volume at the flue outlet of the outdoor unit is measured to be Q2; when the indoor unit on the second highest floor (g floor) is turned on, the air volume at the flue outlet of the outdoor unit is measured to be Qg. Then, the actual air volume information corresponding to the floor information where the indoor unit is turned on is Qg-Q2. The first air volume information output by the indoor unit on each floor at the air outlet of the public flue is Qn, then Qn=(Qg-Q2) / (g)*(nl).

[0115] The air volume on each floor may also be measured according to actual needs to obtain actual air volume information Qn corresponding to the floor information where the indoor unit is located.

[0116] Step 10223: Based on the first air volume information and the corresponding opening time of the indoor unit turned on on each floor, calculate the actual filtered air volume of the filter.

[0117] The total air volume that can be filtered by the filter is Vall, the remaining filtered air volume of the filter is Vrem, and the actual filtered air volume of the filter is Vact. Then the actual filtered air volume of the filter Vact = T1*Q1-T2*Q2-...-Tn*Qn, where Tn represents the opening time of the indoor unit on the nth floor.

[0118] The remaining filtration air volume Vrem of the filter is calculated based on the actual filtration air volume Vact of the filter and the total filtration air volume Vall of the filter;

[0119] Remaining filtered air volume Vrem = Vall - T1*Q1 - T2*Q2 - ... - Tn*Qn.

[0120] This embodiment calculates the actual filtering air volume of the filter by obtaining the number of indoor units turned on, the start-up time and the floor information of the indoor units, thereby solving the problem of calculating the data of the actual filtering air volume of the filter when multiple indoor units on different floors are turned on at the same time, and then determining the remaining life of the filter in this situation. By improving the calculation accuracy of the actual filtering air volume of the filter, the accuracy of obtaining the remaining filtering air volume that represents the remaining life of the filter is improved, thereby ensuring the maximization of the service life of the filter, improving the utilization rate of the filter, and effectively avoiding the waste of resources caused by the actual life of the filter not being reached, reducing user usage costs, and the environmental pollution caused by the early reaching of the actual life of the filter, and improving the flue smoke exhaust effect.

[0121] Example 4

[0122] The calculation method of the filter screen life of this embodiment is a further improvement of the embodiment 1. Specifically:

[0123] Figure 4 This is a method flow chart corresponding to step 102 provided in Example 4 of the present invention; in step 102, the step of obtaining the actual filtered air volume of the filter based on the filter air volume influencing parameter includes:

[0124] Step 10231: Obtain the actual gear parameters of the indoor unit of the floor information.

[0125] In this embodiment, the parameters affecting the filter air volume include the number of indoor units turned on, the time of turning on, the floor information and the gear information. The number of indoor units turned on, the time of turning on, the floor information and the gear information will affect the actual filtering air volume of the filter.

[0126] In this embodiment, when the indoor unit has multiple gears, when the gear of the indoor unit is b, the actual gear parameter corresponding to the gear b is Mb.

[0127] Step 10232: Obtain the reference gear parameters of the indoor unit and the reference air volume corresponding to the reference gear parameters.

[0128] When the indoor unit has multiple gears, the air volume at the public flue outlet of the indoor unit at each gear is tested to obtain the gear parameters M1 to Ma; the reference air volume corresponding to the gear parameter Ma is Qna, and the gear parameter Ma is used as the reference gear parameter of the indoor unit, and the reference air volume corresponding to the gear parameter Ma is Qna as the reference air volume. The reference air volume is used to calculate the air volume of the indoor unit at different gears.

[0129] Step 10233: Based on the reference gear parameter, the reference air volume, and the actual gear parameter, calculate and obtain the second air volume information output by each turned-on indoor unit at the air outlet of the common flue.

[0130] When the indoor unit gear is in gear b, its gear parameter is Mb. According to the reference air volume Qna corresponding to the reference gear parameter Ma, the second air volume information output by each turned-on indoor unit in gear b at the air outlet of the public flue is Qnb, then Qnb = Qna*Mb / Ma.

[0131] The air volume of each gear on each floor may also be measured according to actual needs to obtain the second air volume information Qnb output by each turned-on indoor unit at the air outlet of the public flue.

[0132] Step 10234: Based on the second air volume information of the indoor unit turned on on each floor and the corresponding turn-on time, the actual filtered air volume of the filter is calculated.

[0133] According to the second air volume information Qnb output by each turned-on indoor unit at the air outlet of the common flue, the actual filtered air volume Vact of the filter is calculated, Vact=T1*Q1b-T2*Q2b-...-Tn*Qnb, where Tn represents the turn-on time of the indoor unit on the nth layer.

[0134] The remaining filtration air volume Vrem of the filter is calculated based on the actual filtration air volume Vact of the filter and the total filtration air volume Vall of the filter;

[0135] Remaining filtered air volume Vrem = Vall - T1*Q1b - T2*Q2b - ... - Tn*Qnb.

[0136] This embodiment calculates the actual filtering air volume of the filter by obtaining the number of indoor units turned on, the opening time, the floor information and the gear information, thereby solving the problem of calculating the data of the actual filtering air volume of the filter when multiple indoor units on different floors are turned on at the same time and the gears of the indoor units are different, and then determines the remaining life of the filter in this situation, improves the calculation accuracy of the actual filtering air volume of the filter, and then improves the accuracy of obtaining the remaining filtering air volume that represents the remaining life of the filter, ensures the maximization of the service life of the filter, improves the utilization rate of the filter, effectively avoids the waste of resources caused by the actual life of the filter not being reached, reduces user usage costs, and avoids environmental pollution caused by the early reaching of the actual life of the filter, improves the flue smoke exhaust effect, and is beneficial to protecting the environment.

[0137] Example 5

[0138] The calculation method of the filter screen life of this embodiment is a further improvement of the embodiments 1-4. Specifically:

[0139] Figure 5 The method flow chart corresponding to step 103 and step 104 of embodiment 1-4 provided in embodiment 5 of the present invention; after obtaining the total filterable air volume of the filter in step 103, the method further includes:

[0140] Step 1031: Obtain the filtering area of ​​the filter screen.

[0141] In this embodiment, the parameters affecting the filter air volume include the flue outlet area, the number of indoor units turned on, the opening time, the floor information and the gear information; the number of indoor units turned on, the opening time, the floor information and the gear information will affect the actual filtered air volume of the filter; the flue outlet area will affect the total filterable air volume of the filter.

[0142] Step 1032: Calculate and obtain the ratio of the flue outlet area to the filter area.

[0143] The filtration area of ​​the filter is S1, the flue outlet area is S2, and the ratio of the flue outlet area to the filtration area is S2 / S1.

[0144] Step 1033: Update the new filterable total air volume according to the ratio.

[0145] The total filterable air volume Vall*S2 / S1 of the new filter is updated according to the ratio S2 / S1 of the flue outlet area to the filter area.

[0146] The step of calculating the remaining filtered air volume of the filter according to the actual filtered air volume and the total filterable air volume in step 104 includes:

[0147] Step 1041: Calculate the difference between the updated total filterable air volume and the actual filtered air volume, and use the difference as the remaining filtered air volume.

[0148] Calculate the difference between the actual filtered air volume Vact of the filter and the updated total filterable air volume Vall*S2 / S1 of the filter to obtain the remaining filtered air volume Vrem of the filter, Vrem=Vall*S2 / S1-Vact, that is, the remaining filtered air volume Vrem of the filter=Vall*S1 / S2-T1*Q1b-T2*Q2b-……-Tn*Qnb.

[0149] If the diameter of the flue outlet is D and the diameter of the filter is C, the total air volume that can be filtered by the filter is Vall*((D / 2) 2 *π) / ((C / 2) 2 *π)=Vall*D 2 / C 2 At this time, the remaining filtration air volume of the filter Vrem=Vall*D 2 / C 2 -T1*Q1b-T2*Q2b-……-Tn*Qnb.

[0150] If the flue outlet area is equal to the filter area, the ratio of the flue outlet area to the filter area is 1. At this time, the utilization rate of the filter is the highest, that is, the total filterable air volume Vall*S2 / S1 of the updated filter is equal to the total filterable air volume Vall of the filter before the update. Then the remaining filtered air volume Vrem of the filter is Vall-Vact. At this time, the remaining filtered air volume of the filter is Vrem=Vall-T1*Q1b-T2*Q2b-……-Tn*Qnb.

[0151] This embodiment obtains the actual filtered air volume of the filter by obtaining the flue mouth area, the number of indoor units opened, the opening time, the floor information and the gear information, and updates the total filterable air volume of the filter. Then, by calculating the difference between the updated total filterable air volume of the filter and the actual filtered air volume of the filter, the remaining life of the filter in this case is determined by the difference, thereby improving the calculation accuracy of the actual filtered air volume of the filter, and then improving the accuracy of obtaining the remaining filtered air volume that represents the remaining life of the filter, ensuring the maximization of the service life of the filter, improving the utilization rate of the filter, and effectively avoiding the waste of resources caused by the actual life of the filter not being reached, reducing user usage costs, and the environmental pollution caused by the early reaching of the actual life of the filter. The smoke exhaust effect of the flue is improved, which is beneficial to protecting the environment.
