First embodiment
Referring to fig. 1 to 9 in combination, the present embodiment provides a fresh air device 10, which can selectively use the air filtering and purifying functions, so as to avoid the waste caused by the filtering function of the air which does not need to be filtered and purified, and thereby reduce the burden of the filtering component 400, improve the service life of the filtering component 400, and reduce the use cost of users.
Referring to fig. 1 to 3, a fresh air device 10 provided in this embodiment includes a fan assembly 300, a switching member 200, a filter assembly 400, and a device body. The equipment body is provided with an air inlet 101, a first air outlet 102 and a second air outlet 103; the filter assembly 400 is positioned in the equipment body and is arranged close to the first air outlet 102, and the fan assembly 300 is arranged in the equipment body and is used for entering air through the air inlet 101; the switching member 200 is movably connected with the apparatus body to open or close the second air outlet 103. When the second air outlet 103 is in a closed state, the air flows along the air inlet 101, the filter assembly 400 and the first air outlet 102; when the second air outlet 103 is in an open state, the air flows along the air inlet 101 and the second air outlet 103.
It should be noted that, the switching member 200 can open or close the second air outlet 103, and the first air outlet 102 may be in an open state all the time, or may be closed when the second air outlet 103 is opened. The filter assembly 400 is disposed at the first air outlet 102, so that the air flow discharged from the first air outlet 102 is filtered by the filter assembly 400 and then discharged. When the second air outlet 103 is opened,
compared with the fresh air fan in the prior art, the fresh air device 10 provided in this embodiment has at least the following effects: in the case of good air, the air flow entering from the air inlet 101 is discharged through the second air outlet 103; when the air quality is poor, the air flow entering from the air inlet 101 is filtered by the filter assembly 400 and then discharged through the first air outlet 102. That is, in the case that the air is good, the air flow does not pass through the filter assembly 400, so that the ventilation resistance is greatly reduced, the ventilation efficiency is improved, and the indoor efficient ventilation is realized; meanwhile, the burden of the filter assembly 400 is reduced, the service life of the filter assembly 400 is prolonged, and the use cost of a user is reduced. When the air quality is poor, the air flow needs to pass through the filter assembly 400 and then be exhausted from the first air outlet 102, so that the quality of the air exhausted from the first air outlet 102 can be ensured. The fresh air device 10 provided in this embodiment can selectively use the air filtering and purifying functions, so that the waste caused by using the filtering functions without filtering and purifying air is avoided, the burden of the filtering component 400 is reduced, the service life of the filtering component 400 is prolonged, and the use cost of a user is reduced.
Note that, the switching device 200 may be switched automatically or manually. The fresh air device 10 may further be provided with an air detection module, for example, for detecting parameters such as particulate matters and gas components in the air, where the detected result by the air detection module is compared with the preset values of the parameters under ideal conditions, and when the detected air quality after comparison is lower, the switching element 200 is controlled to operate so as to close the second air outlet 103, so that the gas is discharged from the first air outlet 102 after passing through the filter assembly 400. I.e., when the air quality is poor, the incoming air flow is discharged from the first air outlet 102 through the filter assembly 400. Of course, when the air detection module detects that the air outlet needs to be switched, the switching piece 200 may be manually operated to switch the air outlet between the first air outlet 102 and the second air outlet 103.
It can be appreciated that the second air outlet 103 is selectively opened, which ensures the ventilation efficiency when the air quality is good, and also ensures the ventilation quality when the air quality is bad, thereby providing better experience for the user.
In addition, it should be noted that, in the fresh air device 10 provided in this embodiment, an air inlet pipe connected to the air inlet 101 may be provided, and the air inlet pipe is used for transmitting the outdoor air to the air inlet 101 when the fan assembly 300 is in the working state.
Referring to fig. 5, optionally, the apparatus body includes a first panel 110, a second panel 120 and a shroud 130, an air inlet 101 is disposed on the first panel 110, a first air outlet 102 is disposed on the shroud 130, a second air outlet 103 is disposed on the second panel 120, the first panel 110 and the second panel 120 are disposed opposite to each other and are connected with the shroud 130, the first panel 110, the second panel 120 and the shroud 130 enclose an installation space, the fan assembly 300 and the filter assembly 400 are both installed in the installation space, and the switching member 200 is rotatably disposed in the installation space and is used for opening or closing the second air outlet 103 when rotating relative to the installation space.
It should be noted that, the switching member 200 is turned to open or close the second air outlet 103. Specifically, in the above implementation, the coaming 130, the first panel 110 and the second panel 120 enclose an installation space, and the installation space is also a flow channel of the gas after passing through the air inlet 101; when the switching piece 200 closes the second air outlet 103, the air in the installation space is discharged from the first air outlet 102 after passing through the filter assembly 400; when the switching member 200 opens the second air outlet 103, the air in the installation space is directly discharged from the second air outlet 103. Obviously, when the air quality is good, the air is directly discharged from the second air outlet 103, so that the ventilation efficiency can be improved; because the filter assembly 400 is not used, the service life of the filter assembly 400 can be ensured, and the cost of a user is saved. When the air quality is poor, the air flows out through the filter assembly 400 and the first air outlet 102 on the coaming 130, so that the ventilation quality can be ensured.
Optionally, the first air outlet 102 and the second air outlet 103 are both in a grille air outlet structure, the coaming 130 may be provided with the first air outlet 102 in a grille structure, and the second panel 120 may also be provided with the second air outlet 103 in a grille structure.

It is to be understood that the air outlet grille 140 may be separately disposed on the second air outlet 103, or the second air outlet 103 may have a grille structure. In this embodiment, the second air outlet 103 is provided with a separate air outlet grille 140, and the first air outlet 102 is an opening of a grille structure.
Meanwhile, it should be noted that, during the rotation process, the switching member 200 shields or exposes the air outlet hole 141 for air outlet: when the switching piece 200 shields the air outlet 141, the air outlet 141 is in a closed state, and the air flow cannot pass through, i.e. the second air outlet 103 is in a closed state; when the switching member 200 exposes the air outlet 141, the air outlet 141 is opened, and the air flow can pass through, i.e., the second air outlet 103 is opened.
Alternatively, the switching member 200 is provided with an air outlet portion 210 and a wind shielding portion 220, and the air outlet portion 210 and the wind shielding portion 220 are selectively engaged with the air outlet hole 141; when the air outlet portion 210 is engaged with the air outlet hole 141, the air outlet hole 141 is exposed, and when the wind shielding portion 220 is engaged with the air outlet hole 141, the air outlet hole 141 is completely shielded.
It can be appreciated that when the air outlet portion 210 is opposite to the air outlet hole 141 of the air outlet grille 140, the second air outlet 103 outputs air, and when the air blocking portion 220 is opposite to the air outlet hole 141, the second air outlet 103 does not output air. It should be appreciated that the air outlet 210 is a through hole, and its shape is identical to or slightly larger than the air outlet 141 of the air outlet grille 140, so as to ensure air outlet; the shape of the wind shielding part 220 is identical to or slightly larger than the air outlet 141 to ensure a good wind shielding effect.
