[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 11 As shown, this embodiment discloses a wall-mounted air conditioner air purifier, including an air filtration device. The air filtration device includes a rectangular adjustable frame 1, inside which is a placement rack 2. An air filter element 3 is fixed inside the placement rack 2. Specifically, the upper and lower surfaces of the placement rack 2 are open, and a support rib 21 is provided at the lower part of the placement rack 2. The lower part of the air filter element 3 abuts against the upper part of the support rib 21. A grid plate 4 is covered at the upper opening of the placement rack 2, and the lower part of the grid plate 4 abuts against the upper part of the air filter element 3. The air filter element 3 and the placement rack 2 are connected. The utility model patent with number 202422998096.7 describes a filter device used in an air purification module of an air conditioner. When in use, the air filter device is placed above the return air vent on the top of the indoor unit of the wall-mounted air conditioner, with the lower part of the adjustment bracket 1 abutting against the upper part of the indoor unit. The air filter element 3 can perform the function of air filtration when the air conditioner is in use. When the air filter element 3 needs to be cleaned, simply remove the grid plate 4 and then remove the air filter element 3. After cleaning, it can be directly put back into the placement bracket 2.

[0031] like Figure 4 and Figure 6 As shown, the adjustment frame 1 includes two adjustment units 11, which can move closer to or further away from each other. Specifically, each adjustment unit 11 includes a side plate 111, and adjustment plates 112 are fixed at both ends of the side plate 111. The two adjustment plates 112 are respectively inserted into both sides of the placement frame 2 and can move along the length of the placement frame 2. The upper and lower surfaces of both sides of the placement frame 2 are provided with first limiting grooves 22. The upper and lower ends of the adjustment plates 112 are provided with first limiting ribs 113 adapted to the first limiting grooves 22. The first limiting ribs 113 are inserted into the first limiting grooves 22. By inserting the first limiting ribs 113 into the first limiting grooves 22, the connection between the adjustment unit 11 and the placement frame 2 can be realized. Since the length of the indoor air conditioner unit is not uniform, the overall length of the adjustment frame 1 can be increased by stretching the adjustment unit 11, thereby meeting the usage requirements of indoor air conditioners of different lengths.

[0032] like Figure 2 and Figure 4As shown, the end of the placement rack 2 is connected to the end of the adjustment rack 1 via a corrugated filter 12. One end of the corrugated filter 12 is fixedly connected to the inner side of the side plate 111, and the other end is fixedly connected to the side of the placement rack 2 facing the side plate 111. The two adjustment units 11 are movable to stretch or contract the corrugated filter 12. The corrugated filter 12 is made of mesh fabric. When the adjustment rack 1 is extended, a cavity will appear between the adjustment unit 11 and the placement rack 2, causing some air at the air return vent of the indoor unit of the air conditioner to pass directly through the cavity without passing through the air filter element 3. By setting the corrugated filter 12, this cavity can be covered, thereby achieving coverage of the air return vent of the indoor unit of the air conditioner and improving the filtration effect.

[0033] like Figures 1-4 As shown, an air guide device is also used in conjunction with the air filtration device. The air guide device includes two connecting arms and an air guide cover 8. Since the air guide device also needs to be adapted to air conditioner indoor units of different lengths, the two connecting arms can be close to or far apart from each other. The lower ends of the two connecting arms are connected by the air guide cover 8. By setting the air guide cover 8, the air outlet of the air conditioner indoor unit can be blocked, preventing the air from the air outlet of the air conditioner indoor unit from blowing directly on the human body, which helps to improve the user experience.

[0034] The air guide cover 8 includes two first air guide plates 81 that are hinged to two connecting arms respectively. The two first air guide plates 81 are connected by a second air guide plate 82. Specifically, the two ends of the second air guide plate 82 are inserted into the two first air guide plates 81 respectively. The inner walls of both sides of the first air guide plate 81 are provided with second limiting ribs 811. The two sides of the second air guide plate 82 are provided with protrusions 821 adapted to the second limiting ribs 811. The protrusions 821 are inserted into the area enclosed by the second limiting ribs 811 and the inner walls of the first air guide plates 81. Through the above design, not only can the movable connection between the first air guide plate 81 and the second air guide plate 82 be realized, but it is also convenient to disassemble and assemble the first air guide plate 81 and the second air guide plate 82, which is beneficial to the transportation of the air guide device and the installation by the user.

[0035] like Figure 4 and Figure 5As shown, the connecting arm includes a fixed arm 5, a movable arm 7, and a connecting seat 73. A connecting piece 6 is fixed to the inner side of the fixed arm 5. The connecting piece 6 is a stainless steel metal sheet. The connecting piece 6 includes a vertical section 61 and a horizontal section 63. The vertical section 61 includes a limiting hole 62. The inner side of the fixed arm 5 is provided with a first slot 52. The inner side of the first slot 52 is provided with a protruding buckle 53. The vertical section 61 is inserted into the first slot 52, and the protruding buckle 53 is inserted into the limiting hole 62 for limitation. In use, the vertical section 61 is embedded in the gap between the indoor unit of the air conditioner and the inner wall, and the horizontal section 63 abuts against the top of the indoor unit of the air conditioner, thereby realizing the installation of the air guide device. In order to improve the reliability of its installation, the two connecting pieces 6 can also be connected by ropes after installation. The connecting piece 6 and the fixed arm 5 are limited by the first slot 51 and fixed by the protruding buckle 53, which can not only ensure the fixing effect of the connecting piece 6, but also facilitate the assembly of the connecting piece 6 and the fixed arm 5.

[0036] like Figure 1 and Figure 7 As shown, the fixed arm 5 and the movable arm 7 are hinged together, and the movable arm 7 and the connecting seat 73 are hinged together. Specifically, the movable arm 7 includes a first connecting rod 71 and a second connecting rod 72. One end of the second connecting rod 72 is inserted into the first connecting rod 71, and the other end is hinged to the connecting seat 73 through a connecting member 9. The fixed arm 5 includes a connecting part 51. The upper end of the first connecting rod 71 is provided with a first hinge seat 712. The first hinge seat 712 and the connecting part 51 are also connected through a connecting member 9. The connection method of the first hinge seat 712 and the connecting part 51 is consistent with the connection method of the second connecting rod 72 and the connecting seat 73. With the above design, the air guide shroud 8 can be adjusted at multiple angles, thereby improving the air guiding effect.

[0037] Furthermore, such as Figure 7 and Figure 10As shown, the second connecting rod 72 has a second hinge seat 721 at one end extending beyond the first connecting rod 71. The second hinge seat 721 includes a plurality of second protruding teeth 726, which form an annular region. The connecting seat 73 includes a first annular platform 734, and the outer wall of the first annular platform 734 is provided with three second protruding ribs 735, which are evenly distributed. The first annular platform 734 is inserted into the annular region formed by the plurality of second protruding teeth 726, and the second protruding ribs 735 are inserted into two adjacent second protruding teeth. Between the teeth 726, the second protruding tooth 726 and the second protruding rib 735 can play a locking role, so that the relative positions of the fixed arm 5, the first connecting rod 71, the second connecting rod 72 and the connecting seat 73 will not change during normal use of the air guide device. However, if a rotational force is applied between the second connecting rod 72 and the connecting seat 73, the first annular platform 734 will deform slightly so that the second protruding rib 735 can pass over the second protruding tooth 726, thereby realizing the angle adjustment of the second connecting rod 72 and the connecting seat 73 to meet the air guide requirements.

[0038] Furthermore, the second hinge seat 721 also includes a sleeve 722, the connecting seat 73 includes a through hole 731, the sleeve 722 is inserted into the through hole 731, the connecting member 9 includes a first cover plate 91 and a second cover plate 92 located on both sides of the connecting seat 73, the first cover plate 91 includes a second annular platform 911, the end of the second annular platform 911 is provided with a plurality of buckles 912, the first annular platform 734 passes through the through hole 731 and is inserted into the sleeve 722, the protrusion of the buckle 912 abuts against the side of the sleeve 722 away from the connecting seat 73, and the second cover plate 92 includes a third ring The third annular platform 921 has an annular rib 922 on its outer wall. The third annular platform 921 is inserted into the area surrounded by multiple buckles 912. The annular rib 922 abuts against and squeezes the inner wall of the buckle 912, so that the buckle 912 tends to deform outward. After the second connecting rod 72, connecting seat 73, first cover plate 91 and second cover plate 92 are installed, the buckle 912 can be firmly fastened to the end of the sleeve 722 by the squeezing of the annular rib 922. Moreover, the reaction force of the buckle 912 on the annular rib 922 can fix the second cover plate 92 and prevent the second cover plate 92 from falling off.

[0039] like Figure 10As shown, the connecting seat 73 is snapped into the air guide shroud 8. Specifically, the lower part of the connecting seat 73 is provided with two connecting ribs 732, which are connected by a crossbar 733. The first air guide plate 81 is provided with a protruding plate 83, which includes a fourth limiting groove 84. The protruding plate 83 is inserted between the two connecting ribs 732, and the crossbar 733 passes through the fourth limiting groove 84. The cross sections of the crossbar 733 and the fourth limiting groove 84 are not circular, and the crossbar 733 and the fourth limiting groove 84 are tightly fitted. Through the above cooperation, the quick-installation design of the first air guide plate 81 can be realized, and the rotation of the first air guide plate 81 can also be avoided.

[0040] like Figure 7 , Figure 8 and Figure 11 As shown, the second connecting rod 72 can extend and retract along the length of the first connecting rod 71. Specifically, the first connecting rod 71 includes a second slot 711, and the interior of the second slot 711 is provided with a first rib 713 along its length. The side of the first rib 713 is provided with a plurality of first teeth 714 arranged along its length. The second connecting rod 72 is inserted into the second slot 711. The second connecting rod 72 includes a mounting groove 725, and the first rib 713 and the first teeth 714 are located in the mounting groove 725. A spring sheet 100 is fixed inside the second connecting rod 72. The end of the spring sheet 100 is embedded between two adjacent first teeth 714. A second limiting device is provided inside the second connecting rod 72. The spring piece 100 includes a first bent portion 1001, with second bent portions 1002 connected to both sides of the first bent portion 1001. The first bent portion 1001 is embedded in the second limiting groove 723 for fixation. The two second bent portions 1002 respectively pass through the corresponding third limiting groove 724 and are inserted between two adjacent first protrusions 714. When the second connecting rod 72 is stretched, the second bent portions 1002 of the spring piece 100 will continuously pass over the first protrusions 714. After the position of the second connecting rod 72 is adjusted, the second bent portions 1002 are inserted between the first protrusions 714, thereby preventing the second connecting rod 72 from falling due to the gravity of the air guide 8, thus achieving a self-locking function.
