[0040] When the air conditioner filter dust detection device is fixed on the air conditioner, the first module is arranged on one side of the filter body, the second module is arranged on the other side of the filter body, and the controller outputs the dust state based on the first signal emitted by the controller and the second signal received by the second module.

[0041] The installation assembly enables the air conditioner filter dust detection device to be directly and quickly installed on an air conditioner without the function of detecting the dust state of the air conditioner filter, so that some air conditioners with insufficient functions can be used again, thereby preventing resource waste.

[0042] The internal circuit structure of the controller analyzes the difference after receiving the first signal and the second signal, completes the dust detection of the filter, and obtains the dust state on the filter.

[0043] Embodiment two

[0044] In order to quickly install and detach the air conditioner filter dust detection device, referring to Figures 3-6 The installation assembly 23 is a lock 231, the lock 231 comprises an elastic latch 2311 and a pin hole 2312, the elastic latch 2311 is arranged on the side wall of the assembling plate 21, the pin hole 2312 is arranged on the air conditioner body 1 of the air conditioner 100 and corresponds to the elastic latch 2311, and the elastic latch 2311 cooperates with the pin hole 2312 to realize the positioning and fixing of the assembling plate 21 on the air conditioner body 1.

[0045] The elastic latch 2311 includes a latch rod 23111 and an elastic part 23112. The latch rod 23111 has an insertion end 23113 and a connecting end 23114. The insertion end 23113 is adapted to the pin hole 2312. The elastic part 23112 is connected to the connecting end 23114 of the latch rod 23111, and 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 be firmly connected without affecting the fixation of the assembly plate 21 and the air conditioner body 1 due to being too tight or too loose. The connecting end 23114 is connected to the elastic part 23112 to provide support and power transmission for the extension and contraction of the latch rod 23111.

[0046] 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 the connecting ends 23114 are respectively and reliably connected to the two ends of the elastic part 23112, such as being fixed by welding or adhesive, to ensure that there is no loosening or falling 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.

[0047] The elastic part 23112 is usually in the form of 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 connecting 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 the assembly plate 21 is disassembled, 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.

[0048] The assembly plate 21 is provided with a sliding channel for mounting the elastic latch 2311. The sliding channel has an inner cavity for accommodating the latch rod 23111 and the elastic part 23112. The latch rod 23111 can move axially in the inner cavity of the sliding channel.

[0049] 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. The operation part 23115 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 patterns, cross patterns, 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 for easy gripping of the fingers, improving the comfort and convenience of operation.

[0050] The pin hole 2312 is arranged on the air conditioner main 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, preventing 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, achieving stable connection. On the inner wall of the pin hole 2312, a small protrusion or groove is arranged, which cooperates with the corresponding structure on the surface of the insertion end 23113 of the latch rod 23111, further enhancing the stability of the connection, preventing the latch rod 23111 from accidentally coming out during use.

[0051] The utility model discloses a lock catch 231 structure is established on air conditioner filter screen dust detection device 2, before installation, lock catch 231 is in natural state, and elastic part 23112 provides the elastic force of going out for the bolt bar 23111, and the insertion end 23113 of bolt bar 23111 protrudes 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 bolt bar 23111 is in contact with the edge of pinhole 2312, and assembly plate 21 is pressed to make the insertion end 23113 of bolt bar 23111 enter pinhole 2312 completely, thereby installing assembly plate 21 on air conditioner main body 1. Sliding operation part 23115 on assembly plate 21 is operated in the direction of moving away from pinhole 2312, and the insertion end 23113 of bolt bar 23111 is retracted from pinhole 2312, and when the insertion end 23113 of bolt bar 23111 is completely separated from pinhole 2312, the positioning and fixing effect of elastic bolt 2311 to assembly plate 21 is released, air conditioner filter screen dust detection device 2 is disassembled, the structure is convenient for washing, disinfecting and replacing filter screen main body 22, and the efficiency is improved, which is simple and quick, and is convenient for user to frequently wash and replace filter screen.

[0052] Example three

[0053] In order to make air conditioner filter screen dust detection device fast installation, disassembly, please refer to Figures 7-8 , and the mounting assembly 23 is a spring structure 234, and the spring structure 234 includes a stop spring arranged at the edge position of the assembly plate 21 corresponding to the air conditioner main body 1 of the air conditioner 100, and the stop spring is used for limiting the movement of the assembly plate 21 on the air conditioner main body 1. The stop spring is made of a material with high elasticity and fatigue resistance, which is not easy to deform, maintains good elasticity, and ensures that the stop spring can work stably for a long time.

[0054] The spring structure 234 also includes a mounting groove arranged on the air conditioner main body 1, and the stop spring includes a connecting part fixed in the mounting groove and a free part, and the free part is used to drive the stop spring to extend or retract into the mounting groove. When installing the air conditioner filter screen dust detection device 2, the free part of the stop spring is in the mounting groove, the assembly plate 21 is placed on the assembly hole of the air conditioner main body 1, and the assembly plate 21 is slid right or left to make the assembly plate 21 clamped on the assembly hole. Press the free part of the stop spring to make the stop spring extend from the mounting groove, and the free part abuts against the edge of the lateral wall of the assembly plate 21 to limit the movement of the assembly plate 21. When disassembling the assembly plate 21, press the free part of the stop spring to make the stop spring retract into the mounting groove, and slide the assembly plate 21 left or right to release the limitation of the assembly plate 21, and then disassemble the assembly plate 21 from the air conditioner main body 1. The air conditioner filter screen dust detection device 2 is quickly disassembled through the spring structure 234.

[0055] The elastic sheet structure 234 further comprises a clamping groove corresponding to the free part position on the assembly plate 21, the shape of the clamping groove is matched with the shape of the free part. When the stop elastic sheet is clamped into the clamping groove, the stop elastic sheet can limit the up-down movement of the assembly plate 21, effectively preventing the assembly plate 21 from loosening or moving during the operation of the air conditioner 100.

[0056] The air conditioner filter dust detection device 2 further comprises a positioning guide structure, the positioning structure is arranged on the side away from the elastic sheet structure 234, the positioning guide structure 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 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 body 1. The number of guide protrusions 213 is generally 2-4, which are evenly 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 usually manufactured by an integral molding process such as injection molding or die casting. The guide groove is arranged on the air conditioner body 1 and matched with the guide protrusion 213, and the shape of the guide groove is matched with the corresponding guide protrusion 213.

[0057] When installing the air conditioner filter dust detection device 2, first align the guide protrusion 213 on the assembly plate 21 with the guide groove on the air conditioner 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 body 1. When disassembling the air conditioner filter dust detection device 2, after the stop 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 shifting or shaking during movement, avoiding the assembly plate 21 from colliding with other parts of the air conditioner body 1, thereby protecting the air conditioner filter dust detection device 2 and the air conditioner body 1 from being damaged.

[0058] Embodiment four

[0059] In order to quickly install and disassemble the filter body dust detection device, please refer to Figures 9-11 The installation assembly 23 is a buckle structure 233, the buckle structure 233 comprises a buckle arranged on the edge of the assembly plate 21 and a clamping groove 12 arranged on the corresponding position of the air conditioner body 1 of the air conditioner 100, the buckle is matched and buckled with the clamping groove 12, so that the assembly plate 21 is fixed on the air conditioner body 1.

[0060] 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, and the end of the unlocking part 2332 has a guide slope 2333 for extruding the buckle to unlock it from the card slot 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 integrally molded injection, or can be installed by welding, riveting and the like to ensure stable connection. The unlocking part 2332 has a certain length and elastic coefficient, one end of which 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 be unlocked or clamped from the card slot 12. When cooperating with the card slot 12, it can be deeply inserted into the inside of the card slot 12 and tightly clamped in the card slot 12 under the action of the unlocking part 2332 to prevent the assembly plate 21 from being separated. In some embodiments, the inner side of the unlocking part 2332 is provided with anti-slip protrusions in contact with the inner wall of the card slot 12. To increase the friction between the unlocking part 2332 and the card slot 12, further improve the stability of the connection.

[0061] The buckle is made of elastic material, such as engineering plastic, i.e. polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), etc., to ensure that the buckle has certain elastic deformation capability and can withstand multiple opening and closing operations without being easily damaged.

[0062] 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 part 2332 of the buckle, so that the buckle is completely clamped 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 its shape and size are matched with the unlocking part 2332 of the buckle. The depth of the card slot 12 is designed according to the length of the unlocking part 2332 and the fixing requirement. In this embodiment, the depth of the card slot 12 can make the unlocking part 2332 completely embedded in the card slot 12. For example, for the hook-shaped unlocking part 2332, the depth of the card slot 12 can accommodate the length of the hook-shaped part, and after the hook-shaped part is embedded, the hook-shaped end has a certain distance from the bottom of the card slot 12 to avoid damage to the buckle due to collision. The width of the card slot 12 is slightly greater than the thickness of the unlocking part 2332, which can not only ensure the smooth insertion of the unlocking part 2332, but also limit the displacement of the assembly plate 21 in the horizontal direction to some extent, thereby improving the connection accuracy.

[0063] The inner wall of the card slot 12 is a smooth inner wall to reduce the friction when the unlocking part 2332 is inserted and pulled out, but in some cases where stability is extremely high, some small grooves or protrusions can be provided on the inner wall of the card slot 12, which cooperate with the anti-slip pattern or protrusions of the unlocking part 2332 to further enhance the stability of the connection. The edge of the card slot 12 is chamfered to guide the insertion of the buckle, making it easier for the unlocking part 2332 to align with the card slot 12 and smoothly insert.

[0064] The number of buckles is multiple, and the multiple buckles are evenly distributed along the edge of the assembly plate 21, and the number of card slots 12 is consistent with the number of buckles, so that the connection between the assembly plate 21 and the air conditioner main body 1 is more stable.

[0065] A sealing gasket (not shown in the figure) is provided around the card slot 12, which is compressed when the buckle cooperates with the card slot 12, which can effectively prevent dust, air and other impurities from entering from the connection between the assembly plate 21 and the air conditioner main body 1, improving the sealing performance and overall performance of the air conditioner 100.

[0066] In this embodiment, the air conditioner filter dust detection device 2 and the air conditioner main body 1 are connected by the buckle structure 233. When installing the air conditioner filter dust detection device 2, the user first aligns the buckles on the assembly plate 21 with the card slots 12 of the air conditioner main body 1, and then fixes them. When disassembling, apply pressure on the guide slope 2333 to make the unlocking part 2332 elastically deform, so that the buckle deforms and comes out of the card slot 12, and the air conditioner filter dust detection device 2 is disassembled. This structure is convenient and fast to disassemble the air conditioner filter dust detection device 2, and is convenient for replacement and cleaning of the air conditioner filter dust detection device 2.
