The ventilation switching assembly 3 is used for controlling the air flow communication state, so that the fresh air component 100 can switch at least three states of a first state, a second state and a third state.

It should be noted that "adapted to.. to exhaust" and "adapted to.. to intake" herein both refer to that a ventilation state is exhibited when the ventilation switching assembly 3 does not block the airflow path of the corresponding position, and only "normally open" specifically described is that the ventilation switching assembly 3 cannot block and is always in the ventilation state. Furthermore, it should be noted that the term "adapted to intake air from a location" as used herein is to be interpreted broadly, and includes both direct intake from a location and indirect intake from a location. The term "adapted to exhaust from somewhere" is used herein in a broad sense to include both direct and indirect exhaust from somewhere.

As shown in fig. 9, in the first state, the fan assembly 2 takes in air through the fresh air inlet 11 and exhausts air through the indoor air outlet 13. From this, when the new trend is introduced from outdoor to indoor to needs, can utilize ventilation switching module 3 to switch new trend part 100 first state to at fan subassembly 2 during operation, outdoor air can get into in new trend part 100 through fresh air inlet 11, is handled by first processing module 4, then sends into indoorly through indoor air outlet 13, thereby improves indoor sense of suffocating.

The specific structure of the first processing assembly 4 is not limited, and for example, the first processing assembly 4 may include at least one of a dust removal purification module, a sterilization purification module, a heating module, and a humidification module, and by providing the first processing assembly 4, the fresh air introduced from the outside to the inside of the room meets the indoor environmental requirement.

The second processing assembly 5 is not limited to a specific configuration, and may include at least one of a dust removal purification module, a sterilization purification module, a heating module, and a humidification module, for example, and the second processing assembly 5 is provided to make the processed air meet the indoor environment requirement. In addition, it should be noted that, when the second processing assembly 5 includes a plurality of modules, in some specific examples, at least one module may be selected to operate as needed, for example, several modules may operate, and at the same time, the remaining modules do not operate.

As shown in fig. 11, in the third state, the fan assembly 2 takes in air through the indoor air inlet 12 and exhausts air through the fresh air inlet 11. Therefore, when indoor air needs to be discharged to the outdoor, the ventilation switching component 3 can be used for switching the fresh air component 100 to the third state, so that when the fan component 2 works, the indoor air can enter the fresh air component 100 through the indoor air inlet 12, is processed by the second processing component 5, and is discharged to the outdoor through the fresh air inlet 11, and therefore the effect of exhausting air from the indoor to the outdoor is achieved. In addition, because the exhaust air is treated by the second treatment component 5, the outdoor environment can be protected to a certain extent, and the environmental protection performance is better.

Therefore, according to the utility model discloses new trend part 100 can switch multiple state, satisfies different in-service use requirements. And the air flow path is simple, the wind resistance is small, and the noise effect is achieved. In addition, through set up first processing unit 4 and second processing unit 5 respectively on two different air inlet routes, can be different according to the source of process air, two processing units of separate design respectively set up first processing unit 4 and second processing unit 5 to the same or different to compromise economic nature and treatment effect. For example, the first processing unit 4 is used for processing fresh air introduced from the outdoor to the indoor, and the dust removing capability of the first processing unit 4 is required to be higher than that of the second processing unit 5 because outdoor air may be dusty relative to indoor air, while the second processing unit 5 is used for processing air discharged from the indoor to the indoor or outdoor, and the deodorizing or sterilizing capability of the second processing unit 5 is required to be stronger than that of the first processing unit 4 because indoor air may have heavy odor or more bacteria relative to outdoor air.

For example, the fresh air component 100 may include a combined exhaust air duct R1 and an exhaust air duct R3 (e.g., example two described later). For example, the fresh air component 100 may include a blowdown air passage R2 and a blowdown air passage R3.

For example, the fresh air component 100 includes: the air exhaust duct R1 and the sewage air channel R2 are combined, so that the working mode of exhausting sewage air and simultaneously feeding fresh air or the working mode of exhausting sewage air on both sides and simultaneously feeding fresh air can be realized.

The second outlet channel 2322 and the second outlet channel 2332 are in constant communication via the second communication port 234 (for example, the first open/close valve 31 is not provided at the second communication port 234, or the normally open first open/close valve 31 is provided at the second communication port 234). The second outlet channel 2322 and the indoor outlet 13 are usually blocked (for example, the second outlet channel 2322 is not opposite to the indoor outlet 13, or the position of the indoor outlet 13 opposite to the second outlet channel 2322 is usually closed by the fifth switch valve 34). Therefore, the second air outlet channel 2322 can only outlet air through the second air exhaust channel 2332, and only the air exhaust mode can be realized. When the first air outlet channel 2321 is in a fresh air mode and the second air outlet channel 2322 is in an air exhaust mode, the purposes of exhausting dirty air and simultaneously introducing fresh air can be achieved.

The first air outlet channel 2321 is constantly communicated with the indoor air outlet 13 (for example, the fifth switch valve 34 is not arranged at the position where the indoor air outlet 13 is opposite to the first air outlet channel 2321, or the normally open fifth switch valve 34 is arranged at the position where the indoor air outlet 13 is opposite to the first air outlet channel 2321), and the first air outlet channel 2321 can switch and select whether to output air to the indoor air outlet 13 or simultaneously output air to the indoor air outlet 13 and the first air outlet channel 2331 through the first switch valve 31, so as to switch and realize a fresh air mode or a combined fresh air and air exhaust mode. The second outlet channel 2322 and the second outlet channel 2332 are usually blocked (for example, the second communicating port 234 is provided with the first switch valve 31 in a normally closed state), and the second outlet channel 2322 and the indoor air outlet 13 are usually communicated (for example, the fifth switch valve 34 is not provided at a position where the indoor air outlet 13 is opposite to the second outlet channel 2322, or the normally open fifth switch valve 34 is provided at a position where the indoor air outlet 13 is opposite to the second outlet channel 2322), so that the second outlet channel 2322 can only outlet air through the indoor air outlet 13, and only the fresh air mode can be realized. When the first air outlet channel 2321 is in a fresh air mode and the second air outlet channel 2322 is in a fresh air mode, fresh air can be fed to both sides. When the first air outlet channel 2321 is in a fresh air and exhaust combined mode, and the second air outlet channel 2322 is in a fresh air mode, fresh air can be fed into both sides, and simultaneously, exhaust air is exhausted.
