[0029] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0030] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0031] See also Figures 1-8 As shown, the utility model is a portable filter screen structure, including a middle frame 1, a filter screen 4 is provided on the top of the middle frame 1, a first magnetic patch 5 is symmetrically fixedly installed on one end of the filter screen 4 close to the middle frame 1, and a second magnetic patch 6 is symmetrically provided inside the middle frame 1, the two first magnetic patches 5 and the two second magnetic patches 6 are adsorbed on each other, a panel 2 is provided at one end of the middle frame 1, and an air guide plate 3 is provided at one end of the middle frame 1.

[0032] In the air conditioner running process, the middle frame 1 plays a supporting and connecting other components. The filter screen 4 is symmetrically fixed and installed through the first magnetic sticker 5 at both ends and the second magnetic sticker 6 symmetrically arranged inside the middle frame 1, and is adsorbed to each other, so as to be stably installed on the top of the middle frame 1. When the air flows through the filter screen 4, the filter screen 4 can effectively block the dust, impurities and other pollutants in the air, improve the air quality of the air conditioner outlet air. When the air conditioner is used for a certain period of time, the filter screen 4 accumulates a lot of dust and impurities on the surface, and needs to be cleaned. Since the first magnetic sticker 5 and the second magnetic sticker 6 are only magnetically adsorbed, the user can easily take off the filter screen 4 from the middle frame 1. This design does not need professional operation, greatly improves the convenience of filter screen cleaning, and further ensures the refrigeration effect and air quality of the air conditioner outlet air. The panel 2 at one end of the middle frame 1 and the air deflector 3 respectively play the roles of protecting the internal structure of the air conditioner and guiding the direction of the air conditioner outlet air.

[0033] In addition, the middle frame 1 is provided with a mounting port 101 for mounting the filter screen 4, and the filter screen 4 is provided with a plurality of filter holes 401. The surfaces of the first magnetic sticker 5 and the second magnetic sticker 6 are of different magnetic poles.

[0034] The mounting port 101 provided on the middle frame 1 provides a mounting position for the filter screen 4. When the air conditioner is running, the air is filtered by the filter screen 4 at the mounting port 101. The plurality of filter holes 401 provided on the filter screen 4 allows air to circulate, while the filter holes 401 can block dust, impurities and other pollutants in the air, and play a role in purifying the air.

[0035] Since the surfaces of the first magnetic sticker 5 and the second magnetic sticker 6 are of different magnetic poles, according to the principle of same polarity repulsion and different polarity attraction, when installing the filter screen 4, only the end of the filter screen 4 with the first magnetic sticker 5 is close to the position provided with the second magnetic sticker 6 inside the middle frame 1. The suction force generated by the different magnetic poles will make the filter screen 4 automatically enter the mounting port 101 and be stable at the appropriate position. When it is necessary to disassemble the filter screen 4 for cleaning, the user can easily overcome the small suction force between the different magnetic poles to take off the filter screen 4 from the mounting port 101 of the middle frame 1, which is convenient and fast.

[0036] Example two: based on example one

[0037] At present, most air conditioners are usually installed at high positions, such as high walls or near ceilings. Such installation method is beneficial to air circulation and uniform distribution of indoor temperature. After the air conditioner runs for a period of time, a large amount of dust and impurities will accumulate on the filter screen 4, which needs to be cleaned or replaced regularly. Since the air conditioner is installed at a high position, it is not convenient to disassemble and install the filter screen 4.

[0038] Therefore, the installation of the filter screen 4 can also be as follows:

[0039] In one embodiment, for the above-mentioned middle frame 1, guide rods 7 are symmetrically fixedly installed on the top of the middle frame 1, the filter screen 4 is arranged inside the two guide rods 7, positioning mechanisms 8 are provided at the four corners of the bottom of the filter screen 4, and a positioning fitting plate 9 is fixedly installed inside the middle frame 1.

[0040] The guide rods 7 symmetrically fixed on the top of the middle frame 1 provide a guide for the installation of the filter 4. When the filter 4 needs to be installed, the user can stand on the ground and place the filter 4 between the two guide rods 7. The guide rods 7 can ensure that the filter 4 is accurately installed in the predetermined position to prevent the filter 4 from being offset or misaligned during the installation process. Then, the filter 4 is pushed toward the installation port 101 by hand. When the filter 4 moves to the installation port 101, due to the attraction between the opposite magnetic poles of the first magnetic tile 5 and the second magnetic tile 6, the second magnetic tile 6 on the middle frame 1 at this time will attract the first magnetic tile 5 to the second magnetic tile 6, and the installation is quickly completed. At the same time, the positioning mechanisms 8 set at the four corners of the bottom of the filter 4 cooperate with the positioning fitting plates 9 fixedly installed inside the middle frame 1, and then the positioning mechanism 8 and the positioning fitting plates 9 are accurately docked, thereby further ensuring the accuracy and stability of the installation position of the filter 4. When the air conditioner is running, the filter 4 can filter the air in a stable position to prevent the filtering effect from being affected by the improper position of the filter 4. At the same time, this positioning structure also facilitates the disassembly and installation of the filter 4, allowing the user to complete the operation of the filter 4 more quickly and accurately without having to stand in a high place.

[0041] When the filter 4 needs to be removed for cleaning or other operations, since it is mounted within the two guide rods 7, the filter 4 has a clear direction of movement during removal. First, to overcome the attraction between the first and second magnetic tiles 5, 6, the user can stand on the ground and pull the filter 4 along the two guide rods 7 away from the mounting opening 101, releasing it from the magnetic connection with the second magnetic tile 6 of the middle frame 1. The guide rods 7 then guide the filter 4 smoothly, preventing any shaking or deviation during removal.

[0042] At the same time, the positioning mechanisms 8 at the four corners of the filter 4 and the positioning plates 9 inside the middle frame 1 also assist in removal. As the filter 4 moves, the positioning mechanisms 8 gradually disengage from the positioning plates 9, ensuring smooth removal of the filter 4 from the middle frame 1. This design makes the removal of the filter 4 more convenient and efficient, allowing users to easily complete the removal of the filter 4 without having to stand at a high position.

[0043] In one embodiment, for the above-mentioned guide rod 7, a sliding groove for the filter screen 4 to slide is provided on the guide rod 7, and two of the guide rods 7 are provided with a notch at the installation port 101, the sliding groove is connected to the notch, and the connection is inclined so that the filter screen 4 can enter the installation port 101.

[0044] The positioning mechanism 8 includes a sliding rod 801 , which is slidably installed in the filter 4 , and a spring 802 is sleeved on the circumferential surface of the sliding rod 801 .

[0045] A positioning block 803 is fixedly mounted on the other end of the sliding rod 801 . The other end of the positioning block 803 is tilted. One end of the spring 802 is fixedly mounted on the filter screen 4 , and the other end is fixedly mounted on the positioning block 803 .

[0046] The positioning fitting plate 9 is provided with a circular groove 901 adapted to the plurality of positioning blocks 803 , and a side of the circular groove 901 close to the positioning block 803 is provided with a notch.

[0047] The chute on the guide rod 7 provides a specific sliding track for the filter 4, ensuring that the filter 4 can move smoothly in the designated direction during installation and removal. The notch provided at the installation opening 101 is connected to the chute, and the connection is inclined. This design allows the filter 4 to slide more smoothly into the installation opening 101 through the inclined portion during installation. When the filter 4 needs to be installed, the user can stand on the ground and manually push the filter 4 toward the installation opening 101 along the chute of the guide rod 7. The inclined connection serves as a guide, facilitating the filter 4 to quickly and accurately enter the installation position. Subsequently, the opposite magnetic poles between the first magnetic tile 5 and the second magnetic tile 6 attract the filter 4 to the second magnetic tile 6 of the middle frame 1, completing the installation. At this point, the four positioning blocks 803 fall into their corresponding circular grooves 901, positioning the filter 4. This design makes the removal of the filter 4 more convenient and efficient, allowing the user to easily remove the filter 4 without having to stand at a height.

[0048] When the filter screen 4 needs to be disassembled, the magnetic force between the filter screen 4 and the middle frame 1 is first overcome. Since the guide rod 7 is provided with a sliding groove for the filter screen 4 to slide, and the sliding groove at the mounting port 101 is connected with the missing groove, and the connection is provided in an inclined manner, which provides a clear moving path for the disassembly of the filter screen 4. At this time, the user can stand on the ground and pull the filter screen 4 away from the mounting port 101 along the sliding groove. During the movement, the positioning block 803 at the bottom of the four corners of the filter screen 4. The inclined end of the positioning block 803 first contacts the edge of the circular groove 901 on the positioning fitting plate 9, and as the filter screen 4 continues to move, the positioning fitting plate 9 exerts a pressing force on the positioning block 803. Since the sliding rod 801 is slidingly installed in the filter screen 4, and the positioning block 803 is fixed to one end of the sliding rod 801, under the action of the pressing force, the sliding rod 801 slides towards the inside of the filter screen 4, while compressing the spring 802 fitted on the circumference thereof. Since one end of the spring 802 is fixedly installed on the filter screen 4 and the other end is fixedly installed on the positioning block 803, the positioning block 803 will not fall off during movement. When the positioning block 803 completely exits from the circular groove 901 of the positioning fitting plate 9, the filter screen 4 can continue to move smoothly from the mounting port 101 of the middle frame 1 along the sliding groove and the missing groove of the guide rod 7, completing the disassembly process of the filter screen 4. This design makes the disassembly process of the filter screen 4 more convenient and efficient, and the user can easily complete the disassembly work of the filter screen 4 without standing on a high place.
