[0042] The current filter screen assembly can only filter dust and particles in the air to prevent them from entering the air conditioning system, thereby protecting the normal operation of the air conditioner and reducing the emission of air pollutants. However, for indoor environment, dust is not much, but bacteria breeding odor, toxic gas, smoke seriously affect air quality.

[0043] In this regard, the first thought of the research and development personnel is to fixedly arrange an air purification module on the filter screen to purify bacteria or odor. However, since the air purification module is fixedly arranged, it will affect the air flux of the filter screen when it is not needed to purify bacteria or odor. Therefore, the research and development personnel thought of rotatingly arranging the air purification module to avoid the air purification module from affecting the air flux of the filter screen when the air purification module is not needed to purify air. Since the air purification module is rotatingly arranged, it is easy to collide with the filter screen in daily use and generate noise.

[0044] In this regard, please refer to Figures 1 to 4The embodiment of the present application provides a filter screen assembly 100, which comprises a filter screen body 10 and an air purification module 20, the filter screen body 10 is provided with a matching part; one end of the air purification module 20 is rotatably installed on the filter screen body 10, so that the free end 23 of the air purification module can rotate in the direction close to or away from the filter screen body 10, the air purification module 20 is provided with a fixing part, wherein the air purification module 20 has a working position and an avoiding position; when the air purification module 20 is in the working position, the free end 23 of the air purification module is arranged close to the filter screen body 10, part of the air purification module 20 is shielded on one side of the filter screen body 10, so that the air purification module 20 can purify the air flow flowing to or through the filter screen body 10, and the fixing part is positioned and matched with the matching part, so as to suspend the air purification module 20 in the working position; when the air purification module 20 is in the avoiding position, the free end 23 of the air purification module is away from the filter screen body 10, so as to avoid the air flow flowing to or through the filter screen body 10.

[0045] The embodiment of the present application rotatably installs one end of the air purification module 20 on the filter screen body 10, when the air purification module 20 needs to work, the air purification module 20 is in the working position, at this time, the free end 23 of the air purification module is arranged close to the filter screen body 10, part of the air purification module 20 is shielded on one side of the filter screen body 10, so that the air purification module 20 can purify the air flow flowing to or through the filter screen body 10, thereby purifying bacteria or peculiar smell, thereby enriching the function of the existing filter screen assembly 100, when the air purification module 20 does not need to work, it is rotated to the avoiding position, at this time, the free end 23 of the air purification module is away from the filter screen body 10, so as to avoid the air flow flowing to or through the filter screen body 10, thereby avoiding that the air purification module 20 affects the air flux of the filter screen body 10, when the air purification module 20 is in the working position, the fixing part is positioned and matched with the matching part, so as to suspend the air purification module 20 in the working position, thereby avoiding the impact between the swing of the air purification module 20 and the filter screen body 10 to generate noise.

[0046] It should be emphasized that the air purification module 20 can be arranged on the air inlet side of the filter screen body 10, or can be arranged on the leeward side of the filter screen body 10, which is not limited here.

[0047] It should be noted that the specific positions of the working position and the avoiding position are not limited, as long as the included angle between the air purification module 20 and the filter screen body 10 in the avoiding position is greater than the included angle between the air purification module 20 and the filter screen body 10 in the working position. For example, the included angle between the air purification module 20 and the filter screen body 10 in the avoiding position is 50°-130°, the included angle between the air purification module 20 and the filter screen body 10 in the working position is 0°-50°, and the like, which are not limited herein.

[0048] Specifically, in an embodiment, in the working position, the air purification module 20 is arranged in close contact with the filter screen body 10, so that the air purification module 20 can be perpendicular to the airflow direction, and the airflow can be purified to the maximum extent.

[0049] In addition, in an embodiment, when the air purification module 20 is in the avoiding position, the included angle between the air purification module 20 and the filter screen body 10 is a, and 80°≤a≤100°, specifically, it can be 81°, 82°, and the like. In this way, the included angle between the air purification module 20 and the filter screen body 10 is close to 90°, so that the air purification module 20 can be arranged in parallel with the airflow direction, thereby avoiding affecting the air flux.

[0050] The specific implementation form of the fixed part and the cooperating part is not limited, which can be in the form of combination of multiple magnetic attraction parts, or in the form of multiple buckles, and the like, which are not limited herein.

[0051] In an embodiment, when the air purification module 20 is in the working position, the fixed part and the cooperating part are buckled and matched. In this way, compared with the screwing form, the fixing mode is relatively simple. In the process of directly driving the air purification module 20 to rotate by using the driving device, the cooperating part and the fixed part can be stably connected or separated, and compared with the magnetic attraction mode, the stability of the fixed part is better.

[0052] Further, the parts of the fixed part and / or the cooperating part that are in relative connection are elastically arranged. In this way, in the process of rotating the air purification module 20, at least one of the fixed part and / or the cooperating part can be elastically deformed, so as to realize the buckling or separation of the fixed part and the cooperating part.

[0053] It should be noted that the part of the fixed part and / or the part of the cooperating part relative to the interface is elastically arranged, which can be that the part of the fixed part used for the interface of the cooperating part is elastically arranged, or the part of the cooperating part and the fixed part can be elastically arranged, or the part of the fixed part and the cooperating part can be elastically arranged, which is not limited here, and specifically, the elastic arrangement can be that the corresponding part is made of elastic material, or the interface part can be arranged in a shape that can elastically deform to a certain extent, such as a sheet shape, an arc shape, etc., which is not limited here.

[0054] The specific form of the fixed part and the cooperating part is not limited, which can be a combination of buckles and card holes, or a combination of multiple buckles, etc., which is not limited here.

[0055] Please refer to Figures 5 to 7 In an embodiment, a first abutting part 30 is formed on the fixed part, a second abutting part 40 is formed on the cooperating part, the first abutting part 30 has a first abutting surface 31 abutting the second abutting part 40, and the second abutting part 40 has a second abutting surface 41 abutting the first abutting surface 31; wherein the first abutting surface 31 and the second abutting surface 41 are both arranged as arc surfaces, and the centers of the first abutting surface 31 and the second abutting surface 41 correspondingly are located on both sides of the abutting place 42 of the first abutting part 30 and the second abutting part 40.

[0056] In the technical solution of the embodiment, by arranging the first abutting part 30 and the second abutting part 40, the fixing and separation between the air purification device and the filter screen body 10 can be realized by the abutting and separation of the first abutting part 30 and the second abutting part 40, and the first abutting surface 31 and the second abutting surface 41 are both arranged as arc surfaces, so that when the air purification module 20 rotates, the relative rotation between the first abutting surface 31 and the second abutting surface 41 is more smooth, thereby improving the smoothness of the buckling and separation process.

[0057] At the same time, the specific shape of the first abutting part 30 and the second abutting part 40 is not limited, which can be a spherical shape, so that the spherical outer surface forms the first abutting surface 31 and the second abutting surface 41, or it can be a ring shape, etc., which is not limited here.

[0058] In further embodiments, the first abutting portion 30 and / or the second abutting portion 40 are formed by bending an elastic plate, so arranged that the first abutting portion 30 and / or the second abutting portion 40 are in the shape of a half ring, in the process of rotating abutting, the first abutting surface 31 and / or the second abutting surface 41 are more easily deformed inwardly, so that the first abutting surface 31 and / or the second abutting surface 41 have a greater deformation amount, thereby improving the smoothness of the first abutting portion 30 and the second abutting portion 40 when buckling and separating, and also improving the stability of the two in the buckling process.

[0059] Further, please refer to Figures 4 to 7 It should be noted that when the air purification module 20 is in the working position, the position of the abutting portion 42 between the first abutting surface 31 and the second abutting surface 41 is not limited, which can be the abutting of the end points of the two abutting surfaces, which can be the abutting of the end point of one surface and the non-end point position of the other surface, etc., which is not limited here, in some embodiments, when the air purification module 20 is in the working position, the connection direction between the rotating installation end and the free end of the air purification module 20 is the first direction, the first abutting surface 31 and the second abutting surface 41 have end points in the first direction; when the air purification module 20 is in the working position, the abutting portion 42 of the first abutting portion 30 and the second abutting portion 40 is located at the end point 32 of the first abutting portion close to one side of the air purification module 20, and at the end point 43 of the second abutting portion away from the other side of the air purification module 20.

[0060] It should be noted that taking the first direction as the up-down direction as an example, the end point 32 of the first abutting portion is the lowest point of the first abutting portion 30, and the end point 43 of the second abutting portion is the highest point of the second abutting portion 40. Of course, when the first direction is the left-right direction, the end point can be the leftmost point or the rightmost point.

[0061] In the scheme of the present embodiment, when the air purification module 20 is in the working position, if the air purification module 20 continues to rotate in the direction of the filter screen body 10, the abutting portion 42 of the first abutting portion 30 and the second abutting portion 40 will move in the direction away from the air purification module 20 along the second abutting surface 41, at this time, the mutual abutting deformation between the second abutting portion 40 and the first abutting portion 30 generates a deformation force, thereby preventing it from continuing to move, similarly, when the air purification module 20 wants to return to the avoiding position, the air purification module 20 has a tendency to rotate, at this time, the deformation force of the first abutting portion 30 and the second abutting portion 40 will also prevent it from returning to the avoiding position to a certain extent, thereby suspending the air purification module 20 in the working position.

[0062] Therefore, by locating the abutting position 42 of the first abutting portion 30 and the second abutting portion 40 at the side of the end point 32 of the first abutting portion close to the air purification module 20 and at the side of the end point 43 of the second abutting portion away from the air purification module 20 when the air purification module 20 is located at the working position, the air purification module 20 will be hindered by the deformation force between the first abutting portion 30 and the second abutting portion 40 and prevented from moving in the direction close to or away from the filter screen body 10, of course, when the driving force is greater than a certain value, the first abutting portion 30 and the second abutting portion 40 can rotate relative to each other to generate sliding friction, at this time, the air purification module 20 can also rotate to move between the working position and the avoiding position.

The specific implementation form of the air purification module 20 is not limited, which can only include a purification assembly, or can further include a rotationally arranged mounting piece 21, etc., which is not limited here.

[0066] And, at this time, the first abutting portion 30 is mounted on the rotating shaft 22, and the second abutting portion 40 is mounted on the second skeleton 52 corresponding to the first abutting portion 30, so that, since the first abutting portion 30 is mounted on the rotating shaft 22, the rotating stroke of the first abutting portion 30 can be minimized during the rotation of the air purification device, and interference between other components during the rotation of the first abutting portion 30 is avoided.

[0067] It should be noted that the specific mounting mode of the rotating shaft 22 is not limited, and a rotating hole can be provided on the filter screen, and the rotating shaft 22 is mounted in the rotating hole. In an embodiment, the filter screen body 10 comprises a frame, the mounting bracket 50 is mounted on the frame, and a mounting ring is provided on the frame, and the rotating shaft 22 is mounted on the mounting ring.
