[0038] Figure 1 1 is a schematic structural diagram of a swing blade assembly 100 according to an embodiment of the present invention. Figure 1As shown, and reference Figure 2-8 An embodiment of the present invention provides a swing blade assembly 100, which includes a swing blade body 110. The swing blade body 110 is configured to swing to control the switching state of the air inlet 210 of the air conditioner. A filter duct 120 for accommodating a filter material 150 is formed on the swing blade body 110. The filter duct 120 is configured to communicate with the air inlet 210 and / or form the air inlet 210 when the air inlet 210 is opened, so that the intake air flow flows through.

[0039] In this embodiment, the swing blade assembly 100 is installed at the air inlet 210 of the air conditioner. By swinging the swing blade assembly 100, the air inlet 210 of the air conditioner can be opened or closed. Specifically, when the air conditioner is turned off, the swing blade assembly 100 is in the initial position, which can close the air inlet 210 of the air conditioner. When the air conditioner is turned on, the swing blade assembly 100 swings to a set angle, which can open the air inlet 210 of the air conditioner and enable the filter duct 120 to communicate with the air inlet 210 and / or form the air inlet 210, thereby filtering the intake air flow.

[0040] "The filter duct 120 is connected to the air inlet 210 and / or forms the air inlet 210" includes the following situations: the first situation: the filter duct 120 is connected to the air inlet 210, specifically referring to the filter duct 120 being located upstream or downstream of the air inlet; the second situation: the filter duct 120 forms the air inlet 210, specifically referring to the filter duct 120 can occupy and serve as part or all of the air inlet; the third situation: the filter duct 120 is connected to the air inlet 210 and the filter duct 120 forms the air inlet 210; specifically referring to the filter duct 120 being located upstream or downstream of the air inlet and the filter duct occupies and serves as part of the air inlet.

[0041] Because the present invention provides a swing blade assembly 100 at the air inlet 210 of the air conditioner, when the air conditioner is turned off, the swing blade assembly 100 closes the air inlet 210, thereby preventing small particles of foreign matter from entering the air conditioner. Furthermore, when the air conditioner is turned on, the swing blade assembly 100 opens the air inlet 210, connecting the filter duct 120 with the air inlet 210 and / or forming the air inlet 210. The filter material 150 within the filter duct 120 filters the return air flow, thereby reducing the possibility of particles of foreign matter entering the air conditioner and removing odors or distributing fragrance. Furthermore, by providing the filter material 150 on the swing blade assembly 100, the present invention eliminates the need for a filter device within the air conditioner, thereby saving space within the air conditioner.

[0042] In some optional embodiments of the present invention, the swing blade body 110 further includes a back portion configured to reside inside the air conditioner when the air inlet 210 is closed, and the inlet and outlet 122 of the filter duct 120 are both located on the back portion. In other words, the swing blade body 110 further includes a front portion configured to reside outside the air conditioner when the air inlet 210 is closed. This arrangement allows the filter duct 120 to reside inside the air conditioner when the air inlet 210 is closed, thereby extending the service life of the filter material 150.

[0043] In some alternative embodiments of the present invention, the front and rear of the blade body 110 both have filter ducts 120; when the air inlet 210 of the air conditioner is opened, filter ducts 120 are provided on both sides of the blade body 110 to improve the filtering effect.

[0044] like Figure 3-4 As shown, in some optional embodiments of the present invention, the swing blade body 110 is further formed with a bidirectional swing structure. The bidirectional swing structure is configured to control the swing blade body 110 to open the air inlet 210 from a first end during forward swing or from a second end during reverse swing, wherein the first end and the second end are opposite to each other. By providing the bidirectional swing structure, the swing blade body 110 can swing in both directions, thereby allowing the swing blade body 110 to open the air inlet 210 in both directions.

[0045] Preferably, a windward portion 111 is formed on the first end, and an inlet 121 of the filter air duct 120 is located on the windward portion 111; and a closed wind guiding portion 112 is formed on the second end.

[0046] In this embodiment, by adjusting the swing direction of the swing blade assembly 100, a filtered air intake mode and a normal air intake mode can be achieved, thereby enabling the air conditioner to have both a deodorization mode and a normal mode, thereby providing the air conditioner with multiple functions and better meeting user needs. In other words, this embodiment is primarily intended to conserve filter material 150. When deodorization is not required, filter material 150 can be left unused, thereby extending the service life of filter material 150 and reducing maintenance frequency.

[0047] Specifically, when the air conditioner is operating in the deodorization mode, the swing blade body 110 swings forward to open the air inlet 210 from the first end, and the intake air flow can enter the filter duct 120 through the inlet 121 of the filter duct 120, and the filter material 150 in the filter duct 120 can filter the intake air flow; when the air conditioner is operating in the normal mode, the swing blade assembly 100 swings in the opposite direction to open the air inlet 210 from the second end. Since the air guide part is a closed structure, the intake air flow cannot enter the filter duct 120 at this time, but directly enters the interior of the air conditioner.

[0048] Further preferably, a concave windward surface is formed on the windward portion, and the inlet 121 is located on the windward surface. Specifically, the windward surface is an arc surface, and a plurality of inlets 121 are evenly distributed on the windward surface.

[0049] In this embodiment, the windward surface is set as a concave structure, which can increase the area of ​​the windward surface on the one hand, thereby increasing the number of filter duct 120 inlets 121 on the windward surface; on the other hand, it can hinder the intake air flow from flowing along the windward surface, thereby improving the effective air intake rate of the filter duct 120 inlet 121 and improving the filtering efficiency of the filter duct 120.

[0050] In some alternative embodiments of the present invention, the windward surface is an outward convex structure, for example, the windward surface is an outward convex arc structure; or the windward surface is a planar structure.

[0051] like Figure 1-4 As shown, in some optional embodiments of the present invention, the swing blade body 110 has a first side and a second side relative to each other, the first side is closed, and the second side is configured to face the interior of the air conditioner when the air inlet 210 is closed, and a reverse slope section 113 is formed on the second side, which gradually approaches the first side from the second end to the first end, and the outlet 122 of the filter duct 120 is located on the reverse slope section 113.

[0052] In this embodiment, when the swing blade assembly 100 swings in the opposite direction to open the air inlet 210 from the second end, since the inlet 121 of the filter duct 120 is located at the first end and the outlet 122 of the filter duct 120 is located on the reverse slope, both the outlet 122 and the inlet 121 of the filter duct 120 are located in the low-pressure area. This not only further prevents the incoming airflow from entering the filter duct 120 during normal air intake mode, thereby better implementing normal air intake mode, but also further extends the service life of the filter material 150, reducing maintenance frequency.

[0053] In some optional embodiments of the present invention, the swing blade body 110 has a first side and a second side relative to each other, the first side is closed, and the second side is configured to face the interior of the air conditioner when the air inlet 210 is closed; and the windward surface gradually approaches the second end from the first side to the second side, and the outlet 122 of the filter duct 120 is located at a position on the second side close to the windward part.

[0054] In this embodiment, because the windward surface gradually approaches the second end from the first side to the second side, on the one hand, when the swing body 110 swings in the reverse direction and air enters from the second end, it can effectively prevent the intake airflow from entering the filter channel in normal mode. On the other hand, when the swing body 110 swings in the forward direction and air enters from the first end, it can reduce wind resistance, thereby reducing noise. In addition, because the outlet 122 of the filter duct 120 is located on the second side near the windward portion, on the one hand, when the swing body 110 swings in the reverse direction and air enters from the second end, it can effectively prevent the intake airflow from entering the filter channel in normal mode. On the other hand, when the swing body 110 swings in the forward direction and air enters from the first end, it can reduce the filter stroke, thereby improving filtration efficiency.

[0055] In some optional embodiments of the present invention, the swing blade body 110 includes a box body 114 and a box cover 115. The box body 114 is open on one side, and the filter air duct 120 is located within the box body 114. The inlet 121 and outlet 122 of the filter air duct 120 are both located on the box wall of the box body; the box cover 115 is detachably connected to the opening of the box body.

[0056] In this embodiment, the housing 114 and the removable lid 115 allow for easy opening and closing of the opening of the housing 114, thereby facilitating installation of the filter material 150 within the filter channel and facilitates replacement of the filter material 150 after a period of use. Compared to an integrated swing blade body, the removable swing blade body has a longer service life, thereby reducing operating costs.

[0057] like Figure 3-4 As shown, preferably, a partition 130 is formed within the box body, separating the first and second opposing ends. The partition 130 is formed with a communication hole (not shown) extending in a direction relative to the first and second ends. Furthermore, the inlet 121 of the filter duct 120 is located at the first end, and the outlet 122 is located on the bottom of the box body between the partition 130 and the first end and / or between two adjacent partitions 130. Preferably, outlets 122 are provided on the bottom of the box body, both between the partition 130 and the first end and between two adjacent partitions 130. Further preferably, three partitions 130 are provided within the box body.

[0058] In this embodiment, by setting up partitions 130, the filter duct 120 can be divided into multiple areas, and different filter materials 150 can be conveniently accommodated in different areas; in addition, since different filter materials 150 have different service lives, any filter material can be easily replaced; and the customer's favorite filter material 150 can also be installed in different areas according to their needs.

[0059] Furthermore, the area of ​​the box cover 150 is larger than the opening area of ​​the box body 114. This arrangement is convenient for removing the box cover 150 from the box body 114, thereby making it easy to replace the filter material 150.

[0060] Furthermore, the first end of the box body 114 is a concave windward surface, and the partition 130 in the box body is a curved plate. The curved plate can increase the area of ​​the partition 130 and increase the number of connecting holes on the partition 130, thereby improving the filtering efficiency of the filter duct 120.

[0061] Furthermore, the windward surface gradually approaches the second end from the opening of the box body 114 toward the bottom of the box body 114; the side of the curved plate facing the first end is concave, and the side facing the second end is convex, and the curved plate gradually approaches the second end from the opening of the box body toward the bottom of the box body. The advantages of this arrangement are: on the one hand, when the swing blade body 110 swings in the reverse direction to allow air to enter from the second end, it can enhance the prevention of intake airflow from entering the filter channel in normal mode; on the other hand, when the swing blade body 110 swings in the forward direction to allow air to enter from the first end, both the windward surface and the curved plate can reduce wind resistance, thereby reducing noise.

[0062] Furthermore, the second end of the box body 114 is a closed convex arc structure. When the swing blade body 110 swings in the opposite direction to take in air from the second end, the convex arc structure can reduce wind resistance, improve air intake efficiency, and reduce noise.

[0063] Furthermore, the bottom of the box body 114 is formed with a reversed bevel section 113 and a flat section 116. The reversed bevel section 113 is located near the first end, while the flat section 116 is located near the second end. The outlet 122 of the filter duct 120 is located on the reversed bevel section. Specifically, the reversed bevel section 113 gradually approaches the opening of the box body 114 from the second end toward the first end. When the box cover 115 is placed on the box body 114, the flat section 116 is arranged parallel to the box cover 115. The reversed bevel section 113 is located inside the flat section 116. The bottom of the box body 114 may include multiple reversed bevel sections 113 (e.g., one, two, three, four, or five) spaced apart. Preferably, there are three reversed bevel sections 113. In this embodiment, when the swing blade assembly 100 swings in the opposite direction to open the air inlet 210 from the second end, the outlet 122 and the inlet 121 of the filter duct 120 can be located in the low-pressure area, thereby not only further preventing the incoming air flow from entering the filter duct 120 in the normal air intake mode to better realize the normal air intake mode; it can also further extend the service life of the filter material 150 to reduce the maintenance frequency.

[0064] In some alternative embodiments, the bottom of the box body 114 is flat.

[0065] In some alternative embodiments of the present invention, the partition 130 may also be a flat plate structure or an inclined plate structure; or the partition 130 may be an arc-shaped plate, the side of the arc-shaped plate facing the first end is convex, and the side facing the second end is concave; or, the partition 130 may also be a V-shaped plate, and the concave part of the V-shaped plate faces the first end or the second end.

[0066] In some optional embodiments of the present invention, a rotating shaft 140 is integrally provided or connected to both sides of the length direction of the swing blade body 110. The swing blade body 110 is rotatably mounted at the air inlet 210 of the air conditioner via the rotating shaft 140.

[0067] In some alternative embodiments of the present invention, the inlet of the filter duct 120 is located at the first end of the swing body 110, and the outlet of the filter duct 120 is located at the second end of the swing body 110. In this case, whether the swing body 110 swings forward or backward to open the air inlet of the air conditioner, the intake air can be filtered. In other words, the swing body 110 only has a filtering air intake mode, allowing the air conditioner to only have a deodorizing mode.

[0068] In some optional embodiments of the present invention, the filter material 150 in the filter duct 120 includes odor removal material and / or scented solid particles. Preferably, the odor removal material is activated carbon.

[0069] Figure 5 FIG. 1 is a schematic structural diagram of an air conditioner according to an embodiment of the present invention. Figure 5-8 As shown, an embodiment of the present invention further provides an air conditioner, which includes a body 200 and a swing blade assembly 100. An air inlet 210 is formed on the body 200, and the swing blade assembly 100 is the swing blade assembly 100 as described in any of the above embodiments.

[0070] In this embodiment, when the air conditioner is turned off, the swing blade assembly 100 is swung to close the air inlet 210 of the air conditioner; when the air conditioner is turned on, the swing blade assembly 100 is swung to open the air inlet 210 of the air conditioner.

[0071] Specifically, the air conditioner is a wall-mounted air conditioner, the air inlet 210 is arranged at the top of the body 200, and the swing blade assembly 100 is rotatably installed at the air inlet 210 of the body 200. Mounting holes are provided on both sides of the length direction of the air inlet 210 on the body 200. The mounting holes are used to install the rotating shaft 140 located on both sides of the length direction of the swing blade body 110. The swing blade assembly 100 is rotatably installed in the mounting hole through the rotating shaft 140.

[0072] Preferably, the body 200 is provided with a drive mechanism for driving the swing blade assembly 100 to swing to open or close the air inlet 210. Specifically, the drive mechanism is a motor, wherein the main shaft of the motor is connected to the rotating shaft 140 of the swing blade assembly 100. The swing blade assembly 100 swings in the forward direction through the forward rotation of the motor main shaft, and swings in the reverse direction through the reverse rotation of the motor main shaft.

[0073] In this embodiment, by providing a driving mechanism, the swing blade assembly 100 can be driven to swing according to the instructions of the control device.

[0074] In some alternative embodiments, the air inlet 210 of the air conditioner may also be disposed on the side of the body 200 .

[0075] At this point, those skilled in the art will recognize that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
