As a specific embodiment, as shown in Figure 5, the center of the first filter air inlet 211 and the center of the second filter air inlet 212 are on the same horizontal plane, and the first direction of translation of the damper 231 is the horizontal direction to open the first filter inlet. The air inlet 211 or the second filtered air inlet 212 makes the structure of the fresh air device 10 relatively compact. Obviously, this is only illustrative and not exclusive. For example, the damper 231 can also be translated in an obliquely upward or obliquely upward direction to open the first filtered air inlet 211 or the second filtered air inlet 212 .

In this embodiment, the specific position of the first position is not limited and can be selected as needed. As a specific embodiment, as shown in FIG7 , when the damper 231 is in the first position, its pivot shaft 233 is located between the first filtered air inlet 211 and the second filtered air inlet 212. Obviously, this is only exemplary and not exclusive.

In this embodiment, the second translation direction and the first translation direction are not in the same direction, that is, the first translation direction and the second translation direction intersect. As a specific embodiment, as shown in FIGS. 7 to 12 , the first translation direction is perpendicular to the second translation direction. Obviously, this is only exemplary and not unique.

In some cases, a heating element may be provided at the second filtered air inlet 212 to heat the fresh air in advance. If the damper 231 rotates directly, there will be structural interference between the damper 231 and the heating element, which will hinder the rotation of the damper 231. This arrangement of the air door 231 can avoid structural interference between the air door 231 and other structural components. At the same time, one air door 231 can enable the first filter air inlet 211 and the second filter air inlet 212 to be opened individually or simultaneously, so as to The fresh air device 10 can meet several situations such as entering indoor air alone, entering outdoor air alone, or simultaneously entering indoor air and outdoor air, making the functions of the fresh air device 10 diversified.

In some other embodiments, the damper assembly further includes a pivot shaft 233 , an output shaft 235 and a first driving mechanism 236 . The pivot shaft 233 is provided on the damper 231. The output shaft 235 is configured to be disconnected from the pivot shaft 233 when the damper 231 is in the first position, and is coaxially connected to the pivot shaft 233 to drive the pivot shaft 233 to rotate when the damper 231 is in the second position. The first driving mechanism 236 is used to drive the output shaft 235 to rotate.

In this embodiment, the extension direction of the pivot axis 233 is not specifically limited and can be selected as needed. As a specific embodiment, as shown in FIGS. 7 to 12 , the extension direction of the pivot axis 233 is consistent with the second direction, that is, the pivot axis 233 is arranged along the vertical direction. Obviously, this is only illustrative and not exclusive. For example, the pivot shaft 233 may be provided obliquely upward.

In this embodiment, the direction of the output shaft 235 is related to the direction of the pivot shaft 233. That is, when the damper 231 is in the second position, the direction of the output shaft 235 is consistent with the direction of the pivot shaft 233. That is, the output shaft 235 is consistent with the direction of the pivot shaft 233. The rotating shaft 233 is coaxial. That is, when the damper 231 is in the second position, the pivot shaft 233 and the output shaft 235 are both in the vertical direction. The pivot shaft 233 is tilted upward, and the output shaft 235 is also tilted upward. This allows the output shaft 235 to be coaxially connected to the pivot shaft 233 when the damper 231 is in the second position. As shown in FIGS. 7 to 12 , the pivot shaft 233 is arranged along the vertical direction, and the output shaft 235 is also arranged along the vertical direction. Obviously, this is only exemplary and not unique.

In this embodiment, the specific manner of coaxial connection between the output shaft 235 and the pivot shaft 233 is not limited and can be selected as needed. For example, the output shaft 235 and the pivot shaft 233 are connected through electromagnetic adsorption, adhesive connection, or vacuum adsorption.

In this embodiment, when the damper 231 is in the first position, the output shaft 235 is disconnected from the pivot shaft 233, which prevents the output shaft 235 from affecting the translation of the damper 231 in the first direction. When the damper 231 is in the second position, the output shaft 235 is connected to the pivot shaft 233 to drive the pivot shaft 233 to rotate.

In some other embodiments, the first end of the pivot shaft 233 is provided with a third magnetic adsorption component 234 . The output shaft 235 is disposed along the second direction, and a third electromagnetic component 237 is disposed on it, configured to attract the pivot shaft 233 to the damper 231 when it is translated to the first position along the second direction.

In this embodiment, the output shaft 235 is arranged along the second direction, and the magnetic attraction force between the output shaft 235 and the pivot shaft 233 is used not only to connect the output shaft 235 and the pivot shaft 233, but also to make the pivot shaft 233 and the damper 231 move in the second direction. This simple structure makes the fresh air device 10 compact.

In other embodiments, the first direction is a horizontal direction, the second direction is a vertical direction, the output shaft 235 is disposed above the pivot shaft 233 , and the pivot shaft 233 operates under the influence of gravity, the third magnetic adsorption component 234 and the third electromagnetic component. 237 is driven to switch between the first and second positions. The structure of the fresh air device 10 is simple, energy-saving and compact. Obviously, this is not the only implementation. For example, two third electromagnetic components 237 are disposed on both sides of the pivot shaft 233 to control the damper 231 to switch between the first position and the second position.

In some other embodiments, the filter housing 210 further includes a first groove 214 and a second groove 215 . The length direction of the first groove 214 is provided on the second side wall 216 of the filter housing along the first direction, located on the upper side of the pivot shaft 233, and is used for the first end of the pivot shaft 233 to translate, rotate and move along the first end of the pivot shaft 233. Switch between first position and second position.

The length direction of the second groove 215 is provided on the second side wall 216 of the filter housing along the first direction, located on the lower side of the pivot shaft 233, and is used for the second end of the pivot shaft 233 to translate, rotate and move along the second end of the pivot shaft 233. Switch between first position and second position. This fresh air device 10 has a simple and compact structure. Obviously, the way in which the damper 231 realizes its translation and rotation through the pivot shaft 233 disposed in the first groove 214 and the second groove 215 is only exemplary and not unique. For example, the first groove 214 and the second groove 215 are located between the upper side and the lower side of the air door 231. The corresponding positions of the air door 231 cooperate with the first groove 214 and the second groove 215 to realize the position of the air door 231 in the filter housing. Translation and rotation of the second side wall 216.

In some other embodiments, the fresh air device 10 further includes a sensor assembly 240 . The sensor assembly 240 is disposed in the second groove 215 and is configured to be pressed by the second end of the pivot shaft 233 to detect the translation of the pivot shaft 233 to the first position when the pivot shaft 233 translates to the first position along the first direction.

In this embodiment, the sensor component 240 may include a pressure sensor or a capacitive sensor. When the damper 231 moves to the first position, the second end of the pivot shaft 233, that is, the bottom end of the pivot shaft 233 exerts pressure on the sensor assembly 240. At this time, it can be determined that the damper 231 is in the first position. When the damper 231 moves out of the first position, the bottom end of the pivot shaft 233 no longer exerts pressure on the sensor assembly 240, and based on this, it is determined that the damper 231 is out of the first position. This makes the structure of the fresh air device 10 simple and compact.

In some other embodiments, the damper assembly further includes a second driving mechanism. The second driving mechanism is configured to cooperate with the damper 231 to drive the damper 231 to translate in the first direction when the damper 231 is in the first position, and to disengage from the cooperation with the damper 231 when the damper 231 is in the second position.

In this embodiment, the type of the second driving mechanism is not limited and can be selected as needed. The second driving mechanism can be used to drive the damper 231 to translate along the first direction. When the damper 231 is in the second position, the second driving mechanism is out of cooperation with the damper 231 , which prevents the second driving mechanism from affecting the rotation of the damper 231 .

In some other embodiments, the damper 231 has a rack extending along the damper 231 from the pivot axis 233 toward the other side of the damper 231 opposite to the pivot axis 233, and the teeth thereof are arranged downward. The second drive mechanism includes gear 238 . The gear 238 is disposed below the rack 232 and is configured to disengage from the rack 232 when the damper 231 moves to the second position. When the damper 231 moves to the first position, it engages with the rack 232 to drive the damper 231 to translate. The gear 238 meshes with the rack 232 to control the translation of the damper 231, so that the translation of the damper 231 is relatively stable.
