Assembly plate 21 is provided with the arrangement structure for installing filter screen 22, filter screen 22 is detachably arranged at the arrangement structure, and assembly plate 21 is detachably connected on air conditioner main body 1 through positioning assembly 23. In other embodiments of the utility model, filter holes (not shown in the drawing) are arranged on assembly plate 21, the function of filter holes is similar to that of the arrangement structure, as the air inlet of air conditioner 100, when filter screen 22 is not arranged on assembly plate 21, it is arranged in air conditioner main body 1 opposite the position of filter hole, and filter screen 22 and assembly plate 21 are connected together through magnetic attraction structure or other detachable structure, so that when assembly plate 21 is mounted or removed from air conditioner main body 1, filter screen 22 is mounted to or removed from air conditioner main body 1 along with the action of assembly plate 21, and the quick mounting or removal of filter screen is completed.

[0036] The filter screen module 2 of the utility model is simple in structure, can quickly and conveniently detach assembly plate 21 with filter screen 22 from air conditioner main body 1, is beneficial to replacing filter screen 22 or cleaning and disinfecting filter screen 22, avoids damaging filter screen 22 due to excessive force when filter screen 22 is separately detached from air conditioner 100, or causes filter screen 22 to be not cleaned for a long time due to difficult detachment, so that the problem that the filtering effect of filter screen 22 is poor is caused.

[0037] In other embodiments, as shown in FIG. 2, the installation structure is a filter screen mounting hole 211 or a plurality of air inlet holes 212, and the filter screen 22 is arranged in the filter screen mounting hole 211 or on the surface of the air inlet hole 212. Figures 2-3

[0038] When the installation structure is a filter screen mounting hole 211 structure, it is a specific hole structure formed on the assembly plate 21, and the shape, number, and size thereof are determined according to the actual filtering requirements and the design of the assembly plate 21. For example, the shape can be a regular shape such as a circle, a square, a rectangle, or a special-shaped hole according to the special design of the filter screen 22. In some scenarios with high requirements for filtering precision and efficiency, a plurality of small filter screen mounting holes 211 can be arranged on the assembly plate 21, and a small filter screen 22 is arranged in each hole, so that the filtering area is increased and the filtering effect is improved. For some air conditioners 100 with limited space and high requirements for installation convenience, one or more large square or rectangular mounting holes 211 can be used. The shape and size of the mounting hole 211 are matched with the structure of the filter screen 22, so that the filter screen 22 is arranged in the filter screen mounting hole 211.

[0039] In other embodiments, the filter screen 22 and the filter screen mounting hole 211 are connected by a plurality of detachable connection modes (not shown in the figure). If a clamping mode is used, a plurality of clamping grooves 12 are arranged on the hole wall of the filter screen mounting hole 211. The clamping grooves 12 can be continuous clamping grooves 12 uniformly distributed around the hole wall, or a plurality of independent clamping grooves 12 distributed at intervals. Correspondingly, a clamping block matched with the clamping groove 12 is arranged on the circumferential side of the filter screen 22, and the shape and size of the clamping block are accurately matched with the clamping groove 12. During installation, the clamping block on the filter screen 22 is aligned with the clamping groove 12 on the hole wall of the mounting hole 211, and the filter screen 22 is gently pressed or rotated, so that the clamping block is clamped into the clamping groove 12, and the stable installation of the filter screen 22 is realized. During disassembly, the clamping block is only required to be separated from the clamping groove 12 by applying a certain external force, and then the filter screen 22 can be removed.

[0040] In this embodiment, the filter screen mounting hole 211 is used as the installation structure, which can accurately position the filter screen 22 and ensure the close cooperation between the filter screen 22 and the assembly plate 21, so as to reduce the leakage of unfiltered air and improve the filtering efficiency. Since the shape and size of the mounting hole 211 can be customized according to the filter screen 22, it can better adapt to filter screens 22 with different materials, thicknesses, and filtering characteristics, and provide support for diversified filtering requirements. Through the detachable connection mode, the filter screen 22 can be easily installed and disassembled from the assembly plate 21, which is convenient for cleaning and replacing the filter screen 22.

[0041] Please refer to Figure 3 ​When the mounting structure is configured with multiple air inlets 212, these air inlets 212 are evenly or regularly distributed on the mounting plate 21. The shape of the air inlets 212 can be circular, elliptical, square, etc., and their size and spacing are designed according to the air intake requirements and filtration requirements of the air conditioner 100. For example, in some high-volume air conditioners 100, the diameter of the air inlets 212 will be larger, and the spacing will also be relatively larger to ensure sufficient air intake; while in air conditioners 100 with extremely high filtration accuracy requirements, the air inlets 212 may be designed to be smaller and denser, so as to ensure a certain air intake while allowing the air to pass through the filter screen 22 for filtration.

[0042] In other embodiments, the filter screen 22 is disposed on the surface of the air inlet 212, and the filter screen 22 is connected to the mounting plate 21 by magnetic attraction, snap-fit ​​connection, screw connection, etc. When using magnetic attraction, a magnetic element is embedded in the edge or surrounding of the air inlet 212, and a magnetic mating element, such as an iron sheet or iron product, is provided at the corresponding position on the filter screen 22. When the filter screen 22 approaches the air inlet 212, the magnetic element and the magnetic mating element attract each other, firmly adhering the filter screen 22 to the surface of the air inlet 212. Snap-fit ​​connection involves providing mutually cooperating snap-fit ​​structures, such as male and female snaps, around the air inlet 212 and on the filter screen 22. During installation, the male and female snaps are aligned and pressed together to secure the filter screen 22. Screw connection involves corresponding screw holes on the mounting plate 21 and the filter screen 22, using screws for fixing. In this embodiment, air can enter directly from the air inlet 212 and be filtered by the filter screen 22, which reduces the resistance to airflow and improves the air intake efficiency of the air conditioner 100.

[0043] In other embodiments, such as Figures 5-7 The positioning component 23 shown is a locking component 231. The locking component 231 includes an elastic pin 2311 and a pin hole 2312. The elastic pin 2311 is located on the side wall of the assembly plate 21. The pin hole 2312 is opened on the air conditioner body 1 of the air conditioner 100 at a position corresponding to the elastic pin 2311. The elastic pin 2311 and the pin hole 2312 cooperate to realize the positioning and fixation of the assembly plate 21 on the air conditioner body 1.

[0044] In other embodiments, the elastic latch 2311 includes a latch rod 23111 having an insertion end 23113 and a connection end 23114, the insertion end 23113 being adapted to the pin hole 2312, and an elastic part 23112 connected to the connection end 23114 of the latch rod 23111, which is used to provide the elastic force for the extension and contraction of the latch rod 23111. In some embodiments, the insertion end 23113 of the latch rod 23111 is provided with a chamfer (not shown in the figure), which is used to guide the smooth insertion of the latch rod 23111 into the pin hole 2312. The diameter tolerance between the insertion end 23113 and the pin hole 2312 is controlled within a small range, generally about ±0.05mm, which ensures that the insertion end 23113 and the pin hole 2312 can achieve stable connection without affecting the fixation of the assembly plate 21 and the air conditioner body 1 due to being too tight or too loose. The connection end 23114 is connected to the elastic part 23112 to provide extension and contraction support and power transmission for the latch rod 23111.

[0045] In other embodiments, the number of latch rods 23111 is 2, which can enhance the stability of the fixation of the assembly plate 21. The two latch rods 23111 are symmetrically distributed on both sides of the elastic part 23112, and their connection ends 23114 are reliably connected to the two ends of the elastic part 23112, such as being fixed by welding or adhesive, to ensure that they do not loosen or fall off during use. Correspondingly, the number of pin holes 2312 is also 2, so that the insertion end 23113 of the latch rod 23111 is inserted into the air conditioner body 1 for fixation.

[0046] In other embodiments, the elastic part 23112 usually adopts a spring structure, such as a spiral compression spring. The spiral compression spring has good elasticity and stability. The material of the spring is usually a metal material with high elasticity and fatigue resistance, which can provide the required elastic force for the latch rod 23111 even if it is frequently subjected to compression and stretching during long-term use. One end of the spring is firmly connected to the connection end 23114 of the latch rod 23111, and the other end is fixed to the side wall of the assembly plate 21. When the latch rod 23111 is inserted into the pin hole 2312, the spring releases the insertion end 23113 to be pushed away from the assembly plate 21, so that the insertion end 23113 is locked in the pin hole 2312. When disassembling the assembly plate 21, an external force is applied to the latch rod 23111 to compress the spring, and the latch rod 23111 is retracted, thereby releasing the fixation of the assembly plate 21.

[0047] In other embodiments, as shown in Figures 6-7 The assembly plate 21 is provided with a sliding channel for mounting the elastic latch 2311, the sliding channel has an inner cavity accommodating the latch rod 23111 and the elastic part 23112, and the latch rod 23111 can make extension and contraction movement in the inner cavity of the sliding channel.

[0048] In other embodiments, the elastic latch 2311 further comprises an operation part 23115, which is arranged at the end of the latch rod 23111 away from the insertion end 23113, and penetrates the assembly plate 21 so that the operation part 23115 can slide on the sliding groove corresponding to its position on the assembly plate 21. The outer surface of the operation part 23115 is provided with anti-slip textures, such as diamond textures, cross textures or granular protrusions, etc. These anti-slip textures can increase the friction between the fingers and the operation part 23115, so that the user can easily push the operation part 23115 to unlock. The shape of the operation part 23115 is usually flat or block-shaped with a certain curvature, so as to better fit the user's fingers and facilitate the user to apply force. In other embodiments, the operation part 23115 can also be provided with grooves or protrusions to facilitate the gripping of the fingers, improving the comfort and convenience of operation.

[0049] In other embodiments, the pin hole 2312 is opened on the air conditioner body 1 at a position corresponding to the elastic latch 2311, and its shape and size are adapted to the insertion end 23113 of the latch rod 23111. The pin hole 2312 is generally a cylindrical hole, and its inner diameter is slightly larger than the outer diameter of the insertion end 23113 of the latch rod 23111. Preferably, the tolerance is controlled between 0.1-0.3mm, so that the latch rod 23111 can be smoothly inserted into the pin hole 2312, and at the same time, a certain fitting precision between the two can be ensured to prevent the assembly plate 21 from shaking or shifting after installation. The depth of the pin hole 2312 is longer than the length of the insertion end 23113 of the latch rod 23111, so as to ensure that the latch rod 23111 can be fully inserted into the pin hole 2312 to achieve stable connection. On the inner wall of the pin hole 2312, a small protrusion or groove is arranged to cooperate with the corresponding structure on the surface of the insertion end 23113 of the latch rod 23111, further enhancing the stability of the connection and preventing the latch rod 23111 from accidentally coming out during use.

[0050] The utility model discloses a lock catch assembly 231 structure is established on filter screen module 2, before installation, lock catch assembly 231 is in natural state, and elastic part 23112 provides the elastic force of going outwards for latch bar 23111, makes the insertion end 23113 of latch bar 23111 protrude on the lateral wall of assembly plate 21.When pushing assembly plate 21 close to air conditioner main body 1, the insertion end 23113 of latch bar 23111 is contacted with the edge of pin hole 2312, and assembly plate 21 is pressed to make the insertion end 23113 of latch bar 23111 enter pin hole 2312 completely, thereby installing assembly plate 21 on air conditioner main body 1. Sliding operation part 23115 is operated in the direction of moving away from pin hole 2312 along the sliding groove on assembly plate 21, and the insertion end 23113 of latch bar 23111 is retracted from pin hole 2312, and when the insertion end 23113 of latch bar 23111 is completely separated from pin hole 2312, the positioning and fixing effect of elastic latch 2311 to assembly plate 21 is released, realizes that filter screen module 2 is dismantled, and the structure is convenient for washing, disinfecting and replacing filter screen module 2, simple and quick operation improves the efficiency, and it is convenient for user to frequently wash and replace filter screen.

[0051] In other embodiments, as shown in Figure 8 The positioning assembly 23 is a magnetic positioning assembly 232, which includes a first magnetic sheet arranged on the air conditioner main body 1 of the air conditioner 100 and a second magnetic sheet arranged at a corresponding position of the assembly plate 21. The first magnetic sheet and the second magnetic sheet are coupled by magnetic force to position and fix the assembly plate 21 on the air conditioner main body 1.

[0052] In other embodiments, the number of first magnetic sheets and second magnetic sheets is multiple. Each second magnetic sheet is arranged on the inner wall of the edge of the assembly plate 21 and is uniformly distributed or arranged according to the structural features of the assembly plate 21. The first magnetic sheets are correspondingly distributed along the positions of the edges of the assembly plate 21 on the air conditioner main body 1 to ensure that each second magnetic sheet can generate magnetic force with the corresponding first magnetic sheet and fix the assembly plate 21 from multiple positions to prevent the assembly plate 21 from shaking or shifting during the operation of the air conditioner 100.

[0053] In other embodiments, as shown in Figure 8 The filter screen module 2 further includes a positioning guide plate 2321 arranged on the air conditioner main body 1. The positioning guide plate 2321 is in contact with the edge of the assembly plate 21 to guide the coupling and positioning of the first magnetic sheet and the second magnetic sheet.

[0054] In other embodiments, the first magnetic sheet is a permanent magnet, and the second magnetic sheet is a magnetic matching part that generates magnetic attraction with the first magnetic sheet. The permanent magnet is a neodymium-iron-boron permanent magnet, and the magnetic matching part is made of iron, cobalt, nickel, or an alloy thereof.

[0055] In other embodiments, the first magnetic sheet is in a columnar structure, and its cross section is circular, square or polygonal, and the second magnetic sheet has a shape and size adapted to the first magnetic sheet. In some embodiments, the first magnetic sheet and the second magnetic sheet have different shapes.

[0056] In other embodiments, the inner side wall of the assembly plate 21 is provided with a notch 11. The overall weight of the assembly plate 21 can be reduced, and on the other hand, the notch 11 provides a convenient force point for the user when installing and disassembling the filter screen module 2. The user can more easily grab and move the assembly plate 21 through the notch 11, especially when disassembling, to facilitate the application of external force to separate the assembly plate 21 from the air conditioner body 1. In some embodiments, the notch 11 is provided on the air conditioner body 1, and here, the shape and position of the notch 11 are not limited.

[0057] In other embodiments, as shown in Figures 9-10 The positioning assembly 23 is a buckle structure 233, which includes a buckle provided on the edge of the assembly plate 21 and a buckle groove 12 opened in the corresponding position of the air conditioner body 1 of the air conditioner 100. The buckle and the buckle groove 12 are adapted to be buckled to fix the assembly plate 21 on the air conditioner body 1.

[0058] In other embodiments, the buckle is in a hook structure, which includes a fixed part 2331 connected with the assembly plate 21 and an unlocking part 2332 bent to one side. The end of the unlocking part 2332 has a guide slope 2333 for extruding the buckle to unlock it from the buckle groove 12. The fixed part 2331 is used to fix the buckle on the assembly plate 21, which can be connected with the assembly plate 21 by injection molding, or can be installed by welding, riveting and other methods to ensure stable connection. The unlocking part 2332 has a certain length and elastic coefficient, one end is connected with the fixed part 2331, and the other end is bent to form the guide slope 2333. When the guide slope 2333 is subjected to external force, the unlocking part 2332 can be elastically deformed to unlock or buckle from the buckle groove 12. When cooperating with the buckle groove 12, it can penetrate into the inside of the buckle groove 12 and tightly hold the buckle groove 12 under the action of the unlocking part 2332 to prevent the assembly plate 21 from separating. In some embodiments, the inner side of the unlocking part 2332 is provided with anti-slip protrusions which contact the inner wall of the buckle groove 12. To increase the friction between the unlocking part 2332 and the buckle groove 12, further improve the stability of the connection.

[0059] In other embodiments, the buckle is made of elastic material, such as engineering plastic, i.e. polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS) and the like, which ensures that the buckle has a certain elastic deformation capability and can withstand multiple opening and closing operations without being easily damaged.

[0060] In other embodiments, as shown inFigure 11 As shown, the shape of the card slot 12 is matched with the buckle, the depth of the card slot 12 is greater than the height of the unlocking portion 2332 of the buckle, so that the buckle is completely inserted into the card slot 12, and the width of the card slot 12 is greater than the thickness of the buckle, so that the buckle is inserted into the card slot 12. The card slot 12 is opened on the air conditioner main body 1 at a position corresponding to the buckle, and the shape and size thereof are matched with the unlocking portion 2332 of the buckle. The depth of the card slot 12 is designed according to the length of the unlocking portion 2332 and the fixing requirement. In the embodiment, the depth of the card slot 12 can completely embed the unlocking portion 2332 into the card slot 12. For example, for the hook-shaped unlocking portion 2332, the depth of the card slot 12 can accommodate the length of the hook-shaped portion, and after the hook-shaped portion is embedded, the hook-shaped end portion has a certain distance from the bottom of the card slot 12, so as to avoid damage of the buckle due to collision. The width of the card slot 12 is slightly greater than the thickness of the unlocking portion 2332, so that the unlocking portion 2332 can be smoothly inserted, and the displacement of the assembly plate 21 in the horizontal direction can be limited to a certain extent, so as to improve the connection accuracy.

[0061] In other embodiments, the inner wall of the card slot 12 is a smooth inner wall, so as to reduce the friction force when the unlocking portion 2332 is inserted and pulled out. However, in some occasions with extremely high stability requirement, some small grooves or protrusions can be arranged on the inner wall of the card slot 12, which are matched with the anti-skid lines or protrusions of the unlocking portion 2332, so as to further enhance the stability of the connection. The edge of the card slot 12 is chamfered, so as to guide the insertion of the buckle, and make the unlocking portion 2332 more easily aligned with the card slot 12 and smoothly inserted.

[0062] In other embodiments, the number of buckles is multiple, and the multiple buckles are uniformly distributed along the edge of the assembly plate 21. The number of the card slots 12 is consistent with that of the buckles, so that the connection between the assembly plate 21 and the air conditioner main body 1 is more stable.

[0063] In other embodiments, a sealing gasket (not shown in the figure) is arranged around the card slot 12. When the buckle is matched with the card slot 12, the sealing gasket is compressed, which can effectively prevent impurities such as dust and air from entering from the connection between the assembly plate 21 and the air conditioner main body 1, so as to improve the sealing performance and overall performance of the air conditioner 100.

[0064] In the embodiment, the filter screen module 2 and the air conditioner main body 1 are connected through the buckle structure 233. When the filter screen module 2 is installed, the user first aligns the buckle on the assembly plate 21 with the card slot 12 of the air conditioner main body 1, and then completes the fixation. When disassembling, pressure is applied on the guide inclined surface 2333 to make the unlocking portion 2332 elastically deform, so that the buckle is deformed and comes out of the card slot 12, and the disassembly of the filter screen module 2 is completed. The structure is convenient and fast for disassembling the filter screen module 2, and is convenient for replacing and cleaning the filter screen module 2.

When the stop spring 234 is arranged on the air conditioner main body 1 and the assembly plate 21 is placed in the assembly hole of the air conditioner main body 1, the stop spring 234 abuts against the side edge of the assembly plate 21 to limit the movement of the assembly plate 21 and fix it on the air conditioner main body 1. When the stop spring 234 is arranged at the side edge of the assembly plate 21 in the waiting installation state, the stop spring 234 is arranged on the side of the assembly plate 21 away from the air conditioner main body 1. The assembly plate 21 is placed on the assembly hole of the air conditioner main body 1, the stop spring 234 is clamped into the installation slot of the air conditioner main body corresponding to the position of the stop spring 234 to limit the movement of the assembly plate 21 and fix it on the air conditioner main body 1.

[0066] In other embodiments, the stop spring is made of a material with high elasticity and fatigue resistance, which is not easy to deform and maintains good elasticity to ensure that the stop spring can work stably for a long time.

[0067] In other embodiments, the spring structure 234 further includes an installation slot arranged on the air conditioner main body 1. The stop spring includes a connecting part fixed in the installation slot and a free part. The free part is used to drive the stop spring to extend or retract into the installation slot. When the filter screen module 2 is installed, the free part of the stop spring is in the installation slot. The assembly plate 21 is placed on the assembly hole of the air conditioner main body 1. The assembly plate 21 is slid to the right or left to make the assembly plate 21 clamped on the assembly hole. The free part of the stop spring is pressed to make the stop spring extend from the installation slot. The free part abuts against the side wall edge of the assembly plate 21 to limit the movement of the assembly plate 21. When the assembly plate 21 is disassembled, the free part of the stop spring is pressed to make the stop spring retract into the installation slot. The assembly plate 21 is slid to the left or right to release the limitation of the assembly plate 21 and disassemble the assembly plate 21 from the air conditioner main body 1. The filter screen module 2 is quickly disassembled through the spring structure 234.

[0068] In other embodiments, the spring structure 234 further includes a clamping groove arranged on the assembly plate 21 corresponding to the position of the free part. The shape of the clamping groove is matched with the shape of the free part. When the stop spring is clamped into the clamping groove, the stop spring can limit the movement of the assembly plate 21 in the up-down direction to effectively prevent the assembly plate 21 from loosening or displacing during the operation of the air conditioner 100.

[0069] In other embodiments, the number of the spring structure 234 is multiple.

[0070] In other embodiments, as shown in FIG. 8, the spring structure 234 is arranged on the assembly plate 21. Figure 13As shown, the filter screen module 2 further comprises a positioning guide structure, which is arranged on the side away from the elastic sheet structure 234, and comprises a guide protrusion 213 arranged on the assembly plate 21 and a guide groove (not shown in the figure) arranged on the air conditioner main body 1, the guide protrusion 213 is matched with the guide groove, and the guide protrusion 213 can be slid into the guide groove to position the assembly plate 21 and the air conditioner main body 1. The number of guide protrusions 213 is generally 2-4, which are uniformly distributed on the side edge of the assembly plate 21 away from the elastic sheet structure 234. In order to enhance the connection strength of the guide protrusion 213 and the assembly plate 21, the guide protrusion 213 is generally manufactured by an integral molding process such as injection molding or die casting. The guide groove is arranged on the air conditioner main body 1 and matched with the guide protrusion 213, and the shape of the guide groove corresponds to the guide protrusion 213.

[0071] In the installation of the filter screen module 2, the guide protrusion 213 on the assembly plate 21 is first aligned with the guide groove on the air conditioner main body 1. Through the contact between the guide protrusion 213 and the guide groove, the assembly plate 21 is guided to adjust the position to the assembly hole of the air conditioner main body 1. When disassembling the filter screen module 2, after the stopper elastic sheet is unlocked, the assembly plate 21 slides to the left or to the right, the guide protrusion 213 slides along the guide groove, preventing the assembly plate 21 from deviating or shaking during movement, avoiding the collision between the assembly plate 21 and other components of the air conditioner main body 1, thereby protecting the filter screen module 2 and the air conditioner main body 1 from being damaged.
