[0002] With the development of society and the continuous improvement of people's living standards, air conditioners have become widely popular. The air inlet filter of wall-mounted air conditioners is often installed on the top of the air conditioner. If left on for a long time, the top filter will easily accumulate dust. When the air conditioner is turned on again, the accumulated dust will be released into the air with the air conditioner fan. This not only reduces the air conditioner's performance, but also causes respiratory diseases when inhaled by the human body. Products on the market that place the air inlet filter at the bottom often use clips to attach the filter to the middle frame. However, this solution is prone to failure after repeated disassembly and cleaning, causing the filter element to fall out. Utility Model Content

[0028] In order to make the purpose, technical solution and beneficial effects of the present invention more clearly understood, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] See also Figures 1 to 6 The utility model provides a mounting structure for a filter screen 3, comprising:

[0030] Middle frame 2;

[0031] A filter 3 is detachably mounted on the middle frame 2;

[0032] a connecting assembly, comprising a first connecting portion, a second connecting portion, and a third connecting portion, wherein the first connecting portion, the second connecting portion, and the third connecting portion are configured to connect the middle frame 2 and the filter 3 to fix the filter 3 in a first direction and a second direction;

[0033] The first connecting portion and the second connecting portion are fixed in the same direction, and one of them is a contact structure, and the other and the third connecting portion are movable structures;

[0034] The first direction and the second direction are perpendicular to each other.

[0035] In this embodiment, the middle frame 2 serves as the basic frame for carrying the filter 3, and the filter 3 can be easily removed from the middle frame for easy cleaning or replacement; the connecting assembly consists of a first connecting part, a second connecting part and a third connecting part, which work together to ensure that the filter 3 can be firmly installed in the middle frame 2 in two mutually perpendicular directions (first direction and second direction). The first connecting part and the second connecting part have the same fixed direction. The first connecting part adopts a contact structure, such as magnetic attraction, and relies on physical contact to maintain the position of the filter 3. The second connecting part and the third connecting part are movable structures. In this embodiment, the second connecting part and the third connecting part are snap-on structures, which snap the filter 3 onto the middle frame 2 in the first and second directions, and cooperate with the magnetic attraction of the first connecting part to ensure the structural strength of the installation of the filter 3 while ensuring the convenient disassembly of the filter 3. Even if the second connecting part and the third connecting part fail to snap-on after multiple disassemblies, the first connecting part can ensure that the filter 3 will not fall directly from the middle frame 2, providing convenience during the installation and disassembly process.

[0036] The first connecting portion or the second connecting portion includes a plurality of magnetic component groups, wherein the magnetic component groups are a magnetic component 1 4 and a magnetic component 2 5 respectively provided on the middle frame 2 and the filter screen 3 , and the magnetic component 1 4 and the magnetic component 2 5 are magnetically attracted to each other.

[0037] In this embodiment, each magnetic component group includes two parts, magnetic component 1 4 and magnetic component 2 5. Magnetic component 1 4 is installed on the middle frame 2, and magnetic component 2 5 is installed on the filter 3. Magnetic component 1 4 and magnetic component 2 5 attract each other through magnetic force, thereby fixing the filter 3 on the middle frame 2, realizing the functions of simple installation and convenient disassembly. The magnetic connection can provide sufficient fixing force to prevent the filter 3 from loosening or falling off after the second connection part and the third connection part fail. In addition, regarding the selection of magnetic components, permanent magnets (such as neodymium iron boron magnets) or other materials with strong magnetic properties can be selected to ensure sufficient attraction.

[0038] The magnetic member 1 4 is a strip-shaped structure, and the magnetic member 2 5 is an X-shaped structure.

[0039] In this embodiment, the strip-shaped magnetic member 1 4 can provide a continuous magnetic force distribution, and the cross-shaped magnetic member 2 5 increases the contact area with the magnetic member 1 4 through its flat portion, thereby improving the magnetic attraction, and its curved portion extends in the opposite direction to increase the structural strength during installation.

[0040] The middle frame 2 is provided with a plurality of mounting grooves 201, and a mounting boss 202 is provided in the mounting groove 201. The magnetic component 2 5 is accommodated in the mounting groove 201 and is sleeved on the outside of the mounting boss 202; further, at least one of the two facing surfaces of the mounting boss 202 and the magnetic component 2 5 is provided with a raised rib 203; further, notches 204 are provided on both opposite sides of the mounting groove 201, and the two ends of the magnetic component 2 5 extend into the corresponding notches 204 to limit the movement of the magnetic component 2 5.

[0041] In this embodiment, a mounting groove 201 is provided in the middle frame 2 for mounting the magnetic part 2 5. The magnetic part 2 5 is a sheet metal spring in the shape of a "F" character. A mounting boss 202 is provided inside the mounting groove 201. The magnetic part 2 5 is mounted in the mounting groove 201 and sleeved on the mounting boss 202. When installing, first insert the left end of the sheet metal spring into the notch 204 on the left side of the mounting groove 201, press the middle of the magnetic part 2 5 downward, and extend the right end of the sheet metal spring into the notch 204 on the left side of the mounting groove 201. In the notch 204 at the right end of the slot 201, a guiding slope can be provided at the notch 204 at the right end for ease of installation. Under the action of downward pressure, the "J"-shaped sheet metal spring piece is compressed. When the right side of the sheet metal spring piece extends into the notch 204 at the right end, the middle end of the sheet metal spring piece is sleeved on the mounting boss 202, and the left and right ends of the sheet metal spring piece 2 extend into the notches 204 on the left and right sides of the mounting slot 201 to limit the movement of the sheet metal spring piece and ensure its stability in the mounting slot 201.

[0042] Both ends of the second magnetic member 5 are provided with undercut ribs 501 , and the undercut ribs 501 are elastic. When the end of the second magnetic member 5 extends into the notch 204 , the undercut ribs 501 are deformed and abut against the notch 204 .

[0043] In this embodiment, undercut ribs 501 are provided on both sides of the sheet metal spring piece. When the sheet metal spring piece is assembled on the middle frame 2, the undercut ribs 501 on the left and right ends are firmly embedded in the corresponding notches 204, thereby preventing the sheet metal spring piece from loosening left and right. At the same time, two raised ribs 203 are provided on the middle frame 2. The height of the raised ribs 203 is greater than the height of the sheet metal spring piece, so that the "J"-shaped sheet metal spring piece is simultaneously stressed and stuck on the upper and lower sides after assembly, thereby avoiding the problem of loosening of the sheet metal spring piece in the upper and lower positions.

[0044] The first connection part or the second connection part includes a plurality of matching first clips 6 and a plurality of first slots. One of the filter 3 and the middle frame 2 is provided with the first clip 6, and the other is provided with the first slot. The first slot extends along the first direction.

[0045] In this embodiment, the first direction is defined as the up-down direction, and the first connecting portion is composed of a plurality of first clips 6 provided on the filter 3 and a plurality of first slots provided on the middle frame 2. By using the structure of the first clips 6 and the first slots, the installation structure of the filter 3 is not only more stable but also easier to operate. Furthermore, the third connecting portion includes a plurality of second clips 7 and a plurality of second slots that cooperate with each other. One of the filter 3 and the middle frame 2 is provided with the second clip 7, and the other is provided with the second slot, which extends along the second direction. The second direction is defined as the front-to-back direction. By providing a plurality of second clips 7 on the filter 3 and a plurality of second slots on the middle frame 2, and by positioning the first clips 6, the first slots, the second clips 7, and the second slots in the up-down and front-to-back directions, the flexibility and stability of the installation of the filter 3 are improved.
