DETAILED DESCRIPTION

[0026] In order to facilitate the understanding of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “front”, “rear”, “left”, “right”, “up”, “down”, and “inside” are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of description. They do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0028] The fresh air assembly disclosed in the present invention has a specific structural design so that the fresh air supply angle and range of the fresh air assembly can be adjusted. Figure 1 As shown, the fresh air assembly is composed of a fixed connection part 100, a movable air outlet part 200 and a wireless receiving module. The fixed connection part 100 is used as the structural basis of the fresh air assembly to connect the movable air outlet part 200, and the fixed connection part 100 is used as a communication channel with the outdoor environment. An air inlet is provided on the fixed connection part 100, and the air inlet is connected to the outdoor environment through a pipeline, and the fresh air of the outdoor environment enters the fresh air assembly through the air inlet on the fixed connection part 100. The movable air outlet part 200 is connected to the fixed connection part 100 to form an air duct cavity inside the fresh air assembly to transport fresh air. The movable air outlet part 200 is connected to the fixed connection part 100 in a rotatable connection through a rotating drive mechanism. The air outlet 210 is provided on the movable air outlet part 200, and the outlet direction of the air outlet 210 can be changed by rotating the movable air outlet part 200, thereby changing the outlet angle of the fresh air at the air outlet 210. A fan assembly 220 is also provided in the movable air outlet portion 200. The fan assembly 220 is generally composed of a fan and a fan motor. The operation of the fan assembly 220 forms a negative pressure inside the fresh air assembly, thereby drawing fresh air from the external environment into the fresh air assembly through the air inlet on the fixed connection portion 100, and then delivering the fresh air into the indoor environment through the air outlet 210 under the action of the fan assembly 220; the size of the fresh air supply can be changed by changing the rotation speed of the fan in the fan assembly 220, thereby achieving the purpose of adjusting the fresh air volume and air supply range.

[0029] In the present invention, the fresh air component receives the control signal by setting a wireless receiving module, and a power interface 110 is set on the fresh air component. The power interface 110 can supply power to each fresh air component, so that the fresh air component can be used separately. The user can send a control command to the fresh air component through a remote control, and the wireless receiving module in the fresh air component receives the control command and issues a control signal. Figure 5 As shown, when using fresh air components, multiple fresh air components can be installed on different indoor walls respectively, and different installation heights can be adopted. The air outlet angles and fan speeds of different fresh air components can also be adjusted to be different. Then, fresh air can be supplied from different angles, directions, and heights at different wind speeds, achieving an all-round three-dimensional air supply effect indoors, allowing the fresh air to flow fully in the user's home, bringing the user a better fresh air experience.

[0030] When installing the fresh air component, the fixed connection part 100 of the fresh air component can be directly fixed on the indoor wall by fasteners, but this installation method requires the provision of corresponding mounting holes or other mounting structures on the fixed connection part 100, which will undoubtedly increase the production cost and may also affect the fresh air function of the fresh air component. Therefore, the present invention adds a fresh air bracket 300 to install the fresh air component. Figure 1 and Figure 2 As shown, the fresh air bracket 300 is detachably connected to the fixed connection part 100, and the fixed connection part 100 can be installed on the fresh air bracket 300 by means of magnetism, buckle, etc., and the fresh air bracket 300 is then fixed to the wall by fasteners. The fresh air bracket 300 can adopt an "L"-shaped bending plate, which can cover both sides of the fixed connection part 100 at the same time, protect the fresh air components, and also facilitate the connection between different fresh air components.

[0031] like Figure 1 As shown, the specific structure of the fixed connection part 100 used in the fresh air assembly of the present invention is composed of a fixed upper shell 120, a fixed lower shell 130 and a filter assembly 140. The fixed upper shell 120 and the fixed lower shell 130 are detachably connected by a buckle structure or a fastener to form a shell structure that can accommodate the filter assembly 140; the internal cavity of the fresh air assembly is connected to the external environment by connecting the air inlet duct to the air inlet; the fixed upper shell 120 is connected to the movable air outlet 200 so that the external fresh air entering the fixed connection part 100 can enter the movable air outlet 200 through the air duct in the fixed connection part 100. The filter assembly 140 is installed in the shell structure formed by connecting the fixed upper shell 120 and the fixed lower shell 130. The filter assembly 140 can filter and purify the external air entering the fixed connection part 100, and air treatment functions such as fragrance can be added to the filter assembly 140, so that the filtered air has fragrance, which brings a better user experience.

[0032] In order to facilitate the installation and replacement of the filter assembly 140, the present invention adopts an insertion method to install and fix the filter assembly 140. Specifically, openings are opened at the top of the fixed part upper shell 120 and the fixed part lower shell 130, and the openings at the top of the fixed part lower shell 130 of the fixed part upper shell 120 are arranged relatively and matched with each other. When the fixed part upper shell 120 and the fixed part lower shell 130 are connected, the openings at the top of the fixed part lower shell 130 of the fixed part upper shell 120 are connected to form a filter installation port, and the length and width of the filter installation port are matched with the filter assembly 140. When installing the filter assembly 140, the filter assembly 140 is directly aligned with the filter installation port and then vertically inserted into the fixed connection part 100. The filter assembly 140 is inserted at an angle perpendicular to the airflow direction, thereby forming a complete partition in the cavity of the fixed connection part 100, ensuring that there is no dead angle for filtering and no omission of air filtering.

[0033] like Figure 1 As shown, the specific structure of the movable air outlet part 200 adopted by the fresh air component in the present invention includes, in addition to the fan assembly 220, an air outlet upper shell 230 and an air outlet lower shell 240. The air outlet upper shell 230 and the air outlet lower shell 240 are detachably connected by a snap-type structure or fasteners to form a shell structure with an inner cavity. The fan assembly 220 is installed in the shell structure composed of the air outlet upper shell 230 and the air outlet lower shell 240; the shell structure composed of the air outlet upper shell 230 and the air outlet lower shell 240 is connected to the shell structure composed of the fixed part upper shell 120 and the fixed part lower shell 130.

[0034] In the present invention, the rotatable connection between the fixed connection part 100 and the movable air outlet part 200 is realized by a rotation drive mechanism, such as Figure 1 As shown, the rotation drive mechanism is composed of a drive motor 410, a transmission gear 420 and a rotating ring 430. The drive motor 410 is fixed on the fixed part upper shell 120 of the fixed connection part 100, the transmission gear 420 is fixed on the output end of the drive motor 410, the rotating ring 430 is fixed on the lower shell 240 of the air outlet part and is coaxially arranged with the lower shell 240 of the air outlet part, and the rotating ring 430 is provided with a tooth shape meshing with the transmission gear 420. When the drive motor 410 is working, the transmission gear 420 can be driven to rotate, and the rotation of the transmission gear 420 drives the rotating ring 430 meshing with it to rotate, so that the gear transmission structure composed of the transmission gear 420 and the rotating ring 430 drives the movable air outlet 200 to rotate, and the air outlet angle of the air outlet 210 on the movable air outlet 200 is adjusted. The operation of the rotation drive mechanism depends on the control command received by the wireless receiving module to open and close, and the power interface 110 can be connected to the power supply to provide power for the rotation drive mechanism. In addition, a pressure plate 500 may be added between the fixing portion upper shell 120 and the air outlet portion lower shell 240 to perform axial limiting.

[0035] like Figure 1 As shown, the air outlet 210 of the movable air outlet portion 200 may be covered with a grille or a mesh-like structure to protect the internal structure of the fresh air component; the grille or mesh may be detachably connected to the air outlet 210, or may be integrally formed with the shell of the movable air outlet portion 200.

[0036] In addition to being used alone, the fresh air component of the present invention can also be installed on a conventional air conditioner and used in conjunction with the air conditioner. The present invention also discloses an air conditioner, such as Figures 2 to 4 As shown, the fresh air component described above is installed on the air conditioner body 600, and a wireless transmitting module is provided in the air conditioner body 600 for use in conjunction with the wireless receiving module in the fresh air component. When the fresh air component and the air conditioner are used in conjunction, the wireless transmitting module outputs working parameters including motor start-up, rotation angle, rotation speed, etc. to the wireless receiving module in the fresh air component.

[0037] Users can choose the number of fresh air components on the air conditioner according to their needs, for example Figure 3 As shown, a set of fresh air components is installed at the end of one end of the air conditioner body 600, and it can also be installed as shown in FIG. Figure 4 As shown, two groups of fresh air components are installed at the end of one end of the air conditioner body 600, so as to realize parallel expansion of multiple groups of fresh air components. The fresh air components and the air conditioner body 600 and different fresh air components can be connected by means of magnetic attraction, buckle, etc.; a power interface is also provided at the corresponding position on the air conditioner body 600 to supply power to the installed fresh air components. A position sensor can also be provided in the fresh air component to monitor the distance and height difference between the fresh air component and the air conditioner body 600.

[0038] In order to achieve a better air quality improvement effect, the present invention limits the air outlet angle of the air conditioner body 600 and the air outlet angle of the fresh air component, so that the air outlet angle of the air conditioner body 600 and the air outlet angle of the fresh air component satisfy the following relationship:

[0039] When H 空 -H 新 <0, and ɑ 空 When ≥5°, ɑ 新 =-5°;

[0040] When H 空 -H 新 <0, and ɑ 空 When ≤5°, 新 =-5°;

[0041] When H 空 -H 新 >0,ɑ 新 =(H 空 -H新 )+tgɑ 空 +ɑ 修 ;

[0042] Among them, 空 is the angle between the air supply direction of the air conditioner body 600 and the horizontal direction, 新 H is the angle between the air supply direction of the fresh air component and the horizontal direction. 空 H is the installation height of the air conditioner body 600, 新 is the installation height of the fresh air component, 修 To correct the angle.

[0043] The coordination relationship of the above angles can enable the user to enter the linkage mode when using the air conditioner and the fresh air component at the same time. The fresh air outlet angle of the fresh air component is linked with the air supply range of the air conditioner, and the user can get a better user experience.

[0044] In the present invention, the user experience can be improved by dividing the air supply speed of the air conditioner body and the fresh air component into gears. The air supply speed of the air conditioner body can be divided into seven gears from 1 to 7, and the air supply speed of the fresh air component can be divided into three gears: large, medium, and small; in the linkage mode, the corresponding relationship between the air supply speed of the fresh air component and the air supply speed of the air conditioner body is set as follows: the small gear of the fresh air component corresponds to the two gears 1 and 2 of the air conditioner body; the medium gear of the fresh air component corresponds to the three gears 3, 4, and 5 of the air conditioner body; the large gear of the fresh air component corresponds to the two gears 6 and 7 of the air conditioner body.

[0045] When the fresh air component in the present invention works in conjunction with the air conditioner, when the air conditioner body is turned on or the control APP downloaded by the user is started / refreshed, the number of fresh air components nearby is automatically detected and the signal is connected to identify, manage and control the fresh air components.

[0046] After the fresh air component is started, it automatically enters the linkage mode. The wireless receiving module in the fresh air component receives the instructions output by the wireless transmitting module in the air conditioner body, and sets the air outlet angle and air outlet speed of the fresh air component according to the air outlet angle and air outlet speed of the air conditioner body. In the linkage mode, the air outlet angle of the fresh air component is directly proportional to or quasi-proportional to the air outlet angle of the air conditioner body, and is corrected according to the height difference between the fresh air component and the air conditioner body. The speed of the driving motor in the fresh air component is also directly proportional to or quasi-proportional to the motor speed of the air conditioner body.

[0047] When the fresh air component receives a non-linked command issued by the user through the APP or remote control, the fresh air component enters the single mode, that is, the fresh air component adjusts the angle and speed according to the instructions of the APP or remote control, and no longer responds to the instructions of the air conditioner body.

[0048] When the fresh air component receives a linkage command from the air conditioner body, the user through the APP or the remote control, the fresh air component re-enters the linkage mode with the air conditioner body.

[0049] As one of the preferred schemes, the air supply speed of the air conditioner body is divided into 7 levels from 1 to 7, and the air supply speed of the fresh air component module is divided into 3 levels: large, medium and small. In the linkage mode, the corresponding relationship between the air supply speed of the fresh air component module and the air supply speed of the air conditioner body is: small - 1st and 2nd levels, medium - 3rd, 4th and 5th levels, and large - 6th and 7th levels.
