As shown in fig. 1 to 12, the present embodiment provides a fresh air device 10, the fresh air device 10 includes a filter assembly 200, and the filter assembly 200 includes a filter housing 210, a filter element 220 and a wind valve assembly. Wherein the damper assembly includes a damper 231. The first side wall 216 of the filter housing has a first filter inlet 211 and a second filter inlet 212. The filter member 220 is used to filter the gas flowing into the filter housing 210 from the first filter inlet 211 and/or the second filter inlet 212. The damper 231 is configured to translate in a first direction to open the first filter intake vent 211 or the second filter intake vent 212 when the first sidewall 216 of the filter housing translates in the first direction, to translate in a second direction to switch between a first position and a second position when translated in the first direction to the first position, and to rotate relative to the first sidewall 216 of the filter housing to simultaneously open the first filter intake vent 211 and the second filter intake vent 212 when in the second position.
In the present embodiment, the shape of the filter housing 210 is not limited, and may be selected as needed. For example, the filter housing 210 may be rectangular parallelepiped in shape or other irregular shape. In the present embodiment, the first sidewall 216 of the filter housing may be a front sidewall, a rear sidewall, a right sidewall, a left sidewall, an upper sidewall, or a lower sidewall of the filter housing 210. As a specific example, as shown in fig. 1, the first sidewall 216 of the filter housing is one of a front sidewall, a rear sidewall, a right sidewall, and a left sidewall of the filter housing 210.
In this embodiment, specific applications of the first filtering intake vent 211 and the second filtering intake vent 212 are not limited, and may be selected according to needs. As a specific example, the first filtering air inlet 211 is adapted to communicate with the indoor space, and the second filtering air inlet 212 is adapted to communicate with the outdoor space. This enables the fresh air device 10 to introduce indoor air to mix with outdoor air in advance when introducing outdoor air, thereby preventing the introduced outdoor air from being overcooled or overheated. In this embodiment, the shapes of the first filtering air inlet 211 and the second filtering air inlet 212 are not limited and can be selected as needed.
In this embodiment, the relative positions of the first filtering air inlet 211 and the second filtering air inlet 212 are not limited, and may be selected according to the requirement. As a specific example, as shown in FIG. 1, the centers of the first and second filtering air inlets 211 and 212 are on the same horizontal plane. It will be clear that this is only exemplary and not exclusive. For example, the center of the first filter intake vent 211 is lower than the center of the second filter intake vent 212, that is, the second filter intake vent 212 is located obliquely above the first filter intake vent 211.
In the present embodiment, the position of the filter member 220 is not particularly limited and may be selected as needed. As a specific example, as shown in fig. 1 and 2, the filter element 220 is disposed within the filter housing 210. It will be clear that this is exemplary only and not exclusive. For example, the filter element 220 is disposed in the first filter inlet 211 and/or the second filter inlet 212.
In the present embodiment, the damper 231 is configured to translate along the first sidewall 216 of the filter housing to open the first filter intake vent 211 or the second filter intake vent 212. The first direction in which the damper 231 translates is not particularly limited and may be selected as desired. As a specific example, as shown in fig. 1, the centers of the first filtering intake vent 211 and the second filtering intake vent 212 are located on the same horizontal plane, and the first direction of the translation of the damper 231 is the horizontal direction to open the first filtering intake vent 211 or the second filtering intake vent 212, which makes the structure of the fresh air device 10 relatively compact. It will be clear that this is exemplary only and not exclusive. For example, the damper 231 may also be translated in an obliquely upward or obliquely upward direction to open the first filtering intake port 211 or the second filtering intake port 212.
In this embodiment, the specific position of the first position is not limited, and may be selected as needed. As a specific example, as shown in fig. 1, when the damper 231 is at the first position, the pivot axis 233 thereof is located at a position intermediate the first filtering air inlet 211 and the second filtering air inlet 212. It will be clear that this is exemplary only and not exclusive.
In the present embodiment, the second translation direction is not in the same direction as the first translation direction, that is, the first translation direction and the second translation direction intersect. As a specific example, as shown in fig. 1 to 5, the first translation direction is perpendicular to the second translation direction, which is obviously only exemplary and not exclusive.
In some cases, a heating element is disposed at the second filtering air inlet 212 to heat the fresh air in advance. If the damper 231 is directly rotated, structural interference may be formed between the damper 231 and the heating member, thereby preventing the damper 231 from being rotated. The air door 231 of this kind of arrangement can avoid air door 231 to interfere with the structure of other structures, and one air door 231 can make first filtration air intake 211 and second filter air intake 212 possess several kinds of circumstances such as opening alone and opening simultaneously to satisfy several kinds of circumstances such as fresh air device 10 separately enters indoor wind, separately enters outdoor wind and simultaneously enters indoor wind and outdoor wind, make fresh air device 10's function diversified.
In other embodiments, the damper assembly includes a pivot shaft 233, an output shaft 235, and a first drive 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 rotate the pivot shaft 233 when the damper 231 is in the second position. The first drive mechanism 236 is used to drive the output shaft 235 to rotate.
In the present embodiment, the extending direction of the pivot 233 is not particularly limited, and may be selected as needed. As a specific example, as shown in fig. 1 to 5, the extending direction of the pivot shaft 233 coincides with the second direction, that is, the pivot shaft 233 is disposed in a vertical direction. It will be apparent that this is merely exemplary and not exclusive. For example, the pivot shaft 233 may be disposed obliquely upward.
In the present 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 identical to the direction of the pivot shaft 233, that is, the output shaft 235 is coaxial with the pivot shaft 233. That is, when the damper 231 is in the second position, both the pivot shaft 233 and the output shaft 235 are in a vertical orientation. The pivot shaft 233 is in an obliquely upward direction, and the output shaft 235 is also in an obliquely upward direction. This enables the output shaft 235 to be coaxially connected with the pivot shaft 233 when the damper 231 is in the second position. As shown in fig. 1 to 5, the pivot shaft 233 is disposed in a vertical direction, and the output shaft 235 is also disposed in a vertical direction, which is obviously merely exemplary and not exclusive.
In the present embodiment, the specific manner of coaxial connection between the output shaft 235 and the pivot shaft 233 is not limited, and can be selected according to the requirement. For example, the output shaft 235 and the pivot shaft 233 are connected by electromagnetic attraction, adhesive connection, vacuum attraction, or the like.
In the present embodiment, when the damper 231 is in the first position, the output shaft 235 is decoupled 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 rotate the pivot shaft 233.
In other embodiments, the first end of the pivot shaft 233 is provided with a magnetic attraction 234. The output shaft 235 is disposed in the second direction, on which an electromagnetic absorption member 237 is disposed, configured to absorb the pivot shaft 233 thereto in the second direction when the damper 231 is translated to the first position.
In the present embodiment, the output shaft 235 is disposed in the second direction, and the magnetic attraction force between the output shaft 235 and the pivot shaft 233 is used to both connect the output shaft 235 and the pivot shaft 233 and move the pivot shaft 233 and the damper 231 in the second direction. This simple structure makes the structure of new trend device 10 compact.
In some 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 is switched between the first position and the second position under the gravity and the driving of the magnetic attraction member 234 and the electromagnetic attraction member 237. This simple, energy-saving and compact construction of the fresh air device 10. It is apparent that this is not the only embodiment, for example, two electromagnetic absorption members 237 are provided on both sides of the pivot shaft 233 to control the switching of the damper 231 between the first position and the second position.
In other embodiments, the filter housing 210 further includes a first recess 214 and a second recess 215. The length direction of the first groove 214 is disposed on the first sidewall 216 of the filter housing along the first direction, and is located on the upper side of the pivot shaft 233, for the first end of the pivot shaft 233 to translate, rotate and switch between the first position and the second position.
The length direction of the second groove 215 is arranged on the first side wall 216 of the filter housing along the first direction, and is located at the lower side of the pivot shaft 233, and is used for the second end of the pivot shaft 233 to translate, rotate and switch between the first position and the second position. The fresh air device 10 is simple and compact in structure. It is apparent that the manner in which the damper 231 is translated and rotated by the pivot shaft 233 being disposed in the first and second recesses 214 and 215 is merely exemplary and not exclusive. For example, first and second recesses 214 and 215 are located between the upper and lower sides of damper 231, and the respective positions of damper 231 cooperate with first and second recesses 214 and 215 to effect translation and rotation of damper 231 within first sidewall 216 of filter housing.
