[0083] The controller is used to detect dust on the filter based on the light emitted by the filter and the light reflected by the filter to obtain the dust status on the filter. It should be noted that the number of sensors can be changed according to the accuracy and precision of the dust status detection result, and the number of sensors is not limited here.

[0084] From the above description, it can be seen that the above embodiment of the present application realizes the detection of the dust status on the filter net in the air-conditioning system through the photoelectric sensor, and can monitor the cleanliness of the filter net in real time, so as to facilitate the user to clean the dust on the filter net in time or replace the filter net, thereby reducing the detection cost, reducing the risk of dust blockage, maintaining the air inlet of the air-conditioning system unobstructed, and ensuring the efficient operation of the air-conditioning system; at the same time, it avoids energy waste, thereby extending the service life of the air-conditioning system and providing users with a more comfortable and energy-saving experience.

In this embodiment, the first module 111 and the second module 112 are both fixedly connected to the filter 140.

[0097] According to one embodiment of the present application, Figure 7 and 8 As shown, the present application also provides an air conditioning system 100, which at least includes a front cover 120, an air conditioning body 130, and a dust detection device 110, wherein the front cover 120 and the air conditioning body 130 cover the dust detection device 110 and the filter 140.

This design not only improves the sensitivity and accuracy of the detection, but also effectively reduces the impact of external interference factors on the detection results, making the entire dust detection process more efficient and reliable.

[0100] 2. Deep Learning Model

[0107] 3. Differential pressure sensor

[0108] The inventors have found that based on Bernoulli's principle, there is a certain relationship between air velocity (i.e. wind force) and pressure. When the filter is blocked by dust to different degrees, different pressures will be formed on both sides when air flows through the filter installed above and below.

This method can not only effectively evaluate the dust accumulation of the filter, thereby determining whether it needs to be cleaned or replaced, but also optimize the equipment operation mode based on accurate data, improve energy efficiency and extend the service life of the filter. In addition, this design simplifies the maintenance process, reduces the cost of manual inspection, and ensures that the air purification equipment always operates in an efficient state, providing users with a continuously healthy air environment.

[0112] As can be seen from the above description, the above embodiment of the present application accurately measures the pressure on each side by installing multiple pressure sensors on both sides of the filter, and calculates the pressure difference on both sides of the filter based on these data. This method not only improves the accuracy and reliability of pressure detection, but also more accurately reflects the dust accumulation condition of the filter.

[0113] According to one embodiment of the present application, reference is still made to Fig.11 As shown, the dust detection device of the present application further includes: a plurality of geometric pipes for fixing the positions of a plurality of pressure sensors, wherein each geometric pipe is used to fix the position of any one of the pressure sensors.

[0115] As can be seen from the above description, the dust detection device of the above embodiment of the present application uses multiple geometric pipes to fix the position of each pressure sensor, ensuring that each sensor can accurately measure the pressure at a specific position of the filter. This design not only improves the stability of the pressure sensor installation and the accuracy of positioning, reduces the measurement error caused by position offset, but also enhances the reliability of the dust detection device and the consistency of data by optimizing the sensor layout.

[0118] As can be seen from the above description, the dust detection device of the above embodiment of the present application uses an image sensor to shoot the filter, and controls the shooting process and analyzes the image of the filter through the fourth controller to detect the state of dust on it. This method provides a non-contact, intuitive and efficient dust detection method, which can accurately identify the distribution and density of dust on the filter.

[0119] According to one embodiment of the present application, Fig.13 As shown, the image sensor includes a first image sensor 121, the first image sensor 121 is connected to the fourth controller, the first image sensor 121 is arranged on one side of the filter 140, the fourth controller can transmit a shooting signal to the first image sensor 121, the first image sensor 121 is used to shoot the filter 140 to obtain a first image of the filter 140 and transmit it to the fourth controller, the fourth controller analyzes the image of the filter 140 based on an internal algorithm and then outputs the dust status. According to one embodiment of the present application, still refer to Figure 7 , Fig.14 , Fig.15 , Fig.16 As shown, the first image sensor 121 of the dust detection device 110 may also be fixed on the inner surface of the front cover 120 .

[0121] Among them, according to one embodiment of the present application, the image sensor includes a second image sensor, the second image sensor is arranged on the other side of the filter 140, the second image sensor is connected to the fourth controller, the fourth controller can transmit a shooting signal to the second image sensor, the second image sensor is used to shoot the filter 140 to obtain a second image of the filter 140 and transmit it to the fourth controller, the fourth controller analyzes the first image and the second image based on the internal algorithm and then outputs the dust status.

[0122] It should be noted that the present invention does not limit the number of the first image sensor and the second image sensor, and they can be flexibly configured according to system requirements and accuracy.

[0123] It can be seen from the above description that by detecting the dust state on the filter screen through multiple image sensors, a more accurate dust detection result can be obtained.

[0124] Among them, according to one embodiment of the present application, the first controller, or the second controller, or the third controller, or the fourth controller, or the processor is preset with a corresponding dust status threshold, and the first controller, or the second controller, or the third controller, or the fourth controller, or the processor can compare the dust status with the threshold.

[0125] It can be seen from the above description that by setting a corresponding threshold value to give an early warning of the dust status on the filter, it is convenient for the user to clean the dust on the filter in time.

[0126] 5. Quickly disassembled dust detection device

[0127] According to one embodiment of the present application, Fig.17 and Fig.18 As shown, the air conditioning system 100 includes an air conditioning body 130 and a quickly detachable dust detection device 110-1 for installation on the air conditioning body 130, and the quickly detachable dust detection device 110-1 is detachably connected to the air conditioning body 130. The quickly detachable dust detection device 110-1 includes an assembly plate 21 and an installation component 23. The assembly plate 21 is provided with a placement structure for installing a filter body 22, and the assembly plate 21 is detachably connected to the air conditioning body 130 through the installation component 23.

[0128] According to one embodiment of the present application, the quickly detachable dust detection device 110-1 of the present application includes: a detachable mounting component, a first module, a second module and a target controller, the first module, the target controller and the second module are connected in sequence and are all fixed to the detachable mounting component, the detachable mounting component includes an assembly plate, and the assembly plate is used to fix the quickly detachable dust detection device 110-1 to the air-conditioning system 100.

[0129] In which, when the quickly detachable dust detection device 110-1 is fixed to the air-conditioning system 100, the first module is arranged on one side of the filter, and the second module is arranged on the other side of the filter, and the target controller outputs the dust status based on the first signal emitted by the first module and the second signal received by the second module.

[0130] Among them, the first module is the first light-emitting tube or the second light-emitting tube, the second module is an infrared light detector or a laser light detector, the first signal is infrared light or laser light, and the second signal is infrared light or laser light; the target controller is the first controller or the second controller.

[0131] As can be seen from the above description, the installation assembly of the above embodiment of the present application allows the dust detection device that can be quickly disassembled and assembled to be directly and quickly installed on an air-conditioning system that does not have a filter dust status detection function, and can easily replace the dust detection device in the air-conditioning system, so that the air-conditioning system can be used again to prevent waste of resources. The internal circuit structure of the target controller receives the first signal and the second signal and analyzes the difference, completes the dust detection of the filter, and obtains the dust status on the filter.

[0132] In order to enable the quickly detachable dust detection device 110-1 to be quickly installed and disassembled, according to an embodiment of the present application, Fig.19 , Fig. 20 , Fig.21 , Fig. 22 As shown, the installation component 23 is a lock 231, which includes an elastic latch 2311 and a pin hole 2312. The elastic latch 2311 is arranged on the side wall of the assembly plate 21, and the pin hole 2312 is used to be opened on the air-conditioning body 130 of the air-conditioning system 100 at a position corresponding to the elastic latch 2311. The elastic latch 2311 cooperates with the pin hole 2312 to realize the positioning and fixation of the assembly plate 21 on the air-conditioning body 130.

[0133] The elastic latch 2311 includes a latch rod 23111 and an elastic portion 23112. The latch rod 23111 has an insertion end 23113 and a connection end 23114. The insertion end 23113 is adapted to the pin hole 2312. The elastic portion 23112 is connected to the connection end 23114 of the latch rod 23111, and is used to provide a telescopic elastic force for 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), and the chamfer is used to guide the latch rod 23111 to smoothly insert into the pin hole 2312. The diameter tolerance of the insertion end 23113 and the pin hole 2312 is controlled within a small range, generally about ±0.05mm, to ensure that the insertion end 23113 and the pin hole 2312 can be firmly connected, and the fixing of the assembly plate 21 and the air conditioner body 130 will not be affected by being too tight or too loose. The connecting end 23114 is connected to the elastic portion 23112 to provide telescopic support and power transmission for the latch rod 23111 .

[0134] There are two latch rods 23111, which can enhance the stability of the assembly plate 21. The two latch rods 23111 are symmetrically distributed on both sides of the elastic part 23112, and their connecting ends 23114 are respectively reliably connected to the two ends of the elastic part 23112, such as by welding or adhesive fixation, to ensure that they will not loosen or fall off during use. Correspondingly, there are also two pin holes 2312, so that the insertion end 23113 of the latch rod 23111 can be inserted into the air conditioner body 130 for fixation.

[0135] The elastic part 23112 usually adopts a spring structure, such as a helical compression spring. The helical compression spring has good elasticity and stability. The material of the spring is mostly a metal material with high elasticity and fatigue resistance to ensure that the required elastic force can be provided to the latch rod 23111 even if it is frequently squeezed and stretched 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 on the assembly plate 21. When the latch rod 23111 is inserted into the pin hole 2312, the spring is released to push the insertion end 23113 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, the external force acts on the latch rod 23111 to compress the spring, and the latch rod 23111 retracts, thereby releasing the fixation of the assembly plate 21.

[0136] The assembly plate 21 is provided with a sliding channel for installing 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 perform telescopic movement along the axial direction in the inner cavity of the sliding channel.

[0137] The elastic latch 2311 also includes an operating portion 23115, which is arranged at one end of the latch rod 23111 away from the insertion end 23113. The operating portion 23115 passes through the assembly plate 21 so that the operating portion 23115 can slide on the sliding groove corresponding to its position on the assembly plate 21. The outer surface of the operating portion 23115 is provided with anti-skid textures, such as diamond patterns, horizontal patterns or granular protrusions. These anti-skid textures can increase the friction between the fingers and the operating portion 23115, so that the user can easily push the operating portion 23115 to unlock. The shape of the operating portion 23115 is usually flat or block-shaped with a certain curvature to better fit the user's fingers and facilitate the user to apply force. In other embodiments, the operating portion 23115 may also be provided with grooves or protrusions that are convenient for finger gripping to improve the comfort and convenience of operation.

[0138] The pin hole 2312 is provided on the air conditioner body 130 at a position corresponding to the elastic pin 2311, and its shape and size are adapted to the insertion end 23113 of the pin 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 pin rod 23111. Preferably, the tolerance is controlled between 0.1-0.3 mm, so that the pin rod 23111 can be smoothly inserted into the pin hole 2312, and a certain matching accuracy can be ensured between the two 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 pin rod 23111, so as to ensure that the pin rod 23111 can be fully inserted into the pin hole 2312 to achieve a stable connection. A tiny protrusion or groove is provided on the inner wall of the pin hole 2312, which cooperates with the corresponding structure on the surface of the insertion end 23113 of the latch rod 23111 to further enhance the stability of the connection and prevent the latch rod 23111 from accidentally falling out during use.

[0139] According to an embodiment of the present application, a lock buckle 231 structure is provided on the dust detection device 110-1 that can be quickly disassembled and assembled. Before installation, the lock buckle 231 is in a natural state, and the elastic part 23112 provides an outward elastic force for the latch rod 23111, so that the insertion end 23113 of the latch rod 23111 protrudes from the side wall of the assembly plate 21. When the assembly plate 21 is pushed close to the air conditioner body 130, the insertion end 23113 of the latch rod 23111 contacts the edge of the pin hole 2312, and the assembly plate 21 is pressed hard to make the insertion end 23113 of the latch rod 23111 completely enter the pin hole 2312, thereby installing the assembly plate 21 on the air conditioner body 130. Slide the operating part 23115 along the sliding groove on the assembly plate 21 in the direction away from the pin hole 2312, driving the latch rod 23111 to move synchronously in the sliding channel, and the insertion end 23113 of the latch rod 23111 retracts from the pin hole 2312. When the insertion end 23113 of the latch rod 23111 is completely out of the pin hole 2312, the positioning and fixing effect of the elastic latch 2311 on the assembly plate 21 is released, thereby realizing the disassembly of the dust detection device 110-1 that can be quickly disassembled and assembled. This structure facilitates the cleaning, disinfection and replacement of the filter 140, is simple and quick to operate, improves efficiency, and is convenient for users to frequently clean and replace the filter.

[0140] In order to enable the quickly detachable dust detection device 110-1 to be quickly installed and disassembled, according to an embodiment of the present application, Fig.23 and Fig.24As shown, the mounting assembly 23 is a spring structure 234, which includes a stop spring arranged at the edge of the air-conditioning body 130 of the air-conditioning system 100 corresponding to the mounting plate 21, and the stop spring is used to limit the movement of the mounting plate 21 on the air-conditioning body 130. The stop spring is made of a material with high elasticity and fatigue resistance, is not easily deformed, maintains good elasticity, and ensures that the stop spring can work stably for a long time.

[0141] The spring structure 234 also includes a mounting groove, which is arranged on the air conditioner body 130. The stop spring includes a connecting portion and a free portion fixed in the mounting groove, and the free portion is used to drive the stop spring to extend or retract to the mounting groove. When installing the dust detection device 110-1 that can be quickly disassembled, the free portion of the stop spring is in the mounting groove, the assembly plate 21 is placed on the assembly hole of the air conditioner body 130, and the assembly plate 21 is slid to the right or left so that the assembly plate 21 is clamped on the assembly hole. Press the free portion of the stop spring to make the stop spring extend from the mounting groove, and the free portion abuts against the edge of the side wall of the assembly plate 21 to limit the movement of the assembly plate 21. When disassembling the assembly plate 21, press the free portion of the stop spring to make the stop spring retract into the mounting groove, slide the assembly plate 21 to the left or right, release the restriction of the assembly plate 21, and remove the assembly plate 21 from the air conditioner body 130. The quickly detachable dust detection device 110 - 1 is quickly disassembled through the spring structure 234 .

[0142] The spring structure 234 also includes a snap-in groove provided on the assembly plate 21 at a position corresponding to the free portion, and the shape of the snap-in groove matches the shape of the free portion. When the stop spring is inserted into the snap-in groove, the stop spring can limit the movement of the assembly plate 21 in the up and down directions, effectively preventing the assembly plate 21 from loosening or shifting during the operation of the air conditioning system 100.

[0143] The dust detection device 110-1 that can be quickly disassembled and assembled also includes a positioning guide structure, which is arranged on a side away from the spring structure 234. The positioning guide structure includes 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 130. The guide protrusion 213 is adapted to the guide groove, and the guide protrusion 213 can slide into the guide groove to position the assembly plate 21 and the air conditioner body 130. The number of the guide protrusions 213 is generally 2-4, which are evenly distributed on the edge of one side of the assembly plate 21 away from the spring structure 234. In order to enhance the connection strength between the guide protrusion 213 and the assembly plate 21, the guide protrusion 213 is usually manufactured with the assembly plate 21 by an integrated molding process, such as injection molding or die casting. The guide groove is provided on the air conditioner body 130, adapted to the guide protrusion 213, and the shape of the guide groove corresponds to the guide protrusion 213.

[0144] When the dust detection device 110-1 that can be quickly disassembled is assembled, first align the guide protrusion 213 on the assembly plate 21 with the guide groove on the air conditioner body 130. Through the contact between the guide protrusion 213 and the guide groove, the assembly plate 21 is guided to adjust its position to the assembly hole of the air conditioner body 130. When the dust detection device 110-1 that can be quickly disassembled is disassembled, after the stop spring is unlocked, the assembly plate 21 slides to the left or right, and the guide protrusion 213 slides along the guide groove to prevent the assembly plate 21 from deflecting or shaking during the movement, and to prevent the assembly plate 21 from colliding with other parts of the air conditioner body 130, thereby protecting the dust detection device 110-1 that can be quickly disassembled and assembled and the air conditioner body 130 from damage.

[0145] In order to enable the quickly detachable dust detection device 110-1 to be quickly installed and disassembled, according to an embodiment of the present application, Fig.25 , Fig.26 , Fig. 27 As shown, the mounting assembly 23 is a snap-on structure 233, which includes a snap-on arranged on the edge of the assembly plate 21, and a slot 12 opened at a corresponding position of the air-conditioning body 130 of the air-conditioning system 100, and the snap-on and the slot 12 are adapted to fit together so that the assembly plate 21 is fixed to the air-conditioning body 130.

[0146] The buckle is a hook-shaped structure, which includes a fixing portion 2331 connected to the assembly plate 21 and an unlocking portion 2332 bent to one side, and the end of the unlocking portion 2332 has a guiding slope 2333, and the guiding slope 2333 is used to squeeze the buckle so that the buckle is unlocked from the slot 12. The fixing portion 2331 is used to fix the buckle on the assembly plate 21. It can be connected to the assembly plate 21 by injection molding, or it can be installed by welding, riveting, etc. to ensure a stable connection. The unlocking portion 2332 has a certain length and elastic coefficient, one end is connected to the fixing portion 2331, and the other end is bent to form a guiding slope 2333. When the guiding slope 2333 is subjected to an external force, the unlocking portion 2332 can be elastically deformed and unlocked or stuck in the slot 12. When it cooperates with the slot 12, it can penetrate into the slot 12, and the slot 12 is tightly clamped under the action of the unlocking portion 2332 to prevent the assembly plate 21 from detaching. In some embodiments, an anti-skid protrusion is provided on the inner side of the unlocking portion 2332, and the anti-skid protrusion contacts the inner wall of the card slot 12, so as to increase the friction between the unlocking portion 2332 and the card slot 12, and further improve the stability of the connection.

[0147] The buckle is made of elastic material, such as engineering plastics, namely polycarbonate (PC), acrylonitrile-butadiene-styrene copolymer (ABS), etc., to ensure that the buckle has a certain elastic deformation ability while withstanding multiple opening and closing operations without being easily damaged.

[0148] The shape of the card slot 12 is adapted to the buckle, and the depth of the card slot 12 is greater than the height of the buckle unlocking portion 2332, 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 provided at a position corresponding to the buckle on the air conditioner body 130, and its shape and size match the unlocking portion 2332 of the buckle. The depth of the card slot 12 is designed according to the length and fixing requirements of the unlocking portion 2332. In this embodiment, the depth of the card slot 12 can enable the unlocking portion 2332 to be completely embedded in the card slot 12. For example, for the hook-shaped unlocking portion 2332, the depth of the card slot 12 should be able to accommodate the length of the hook-shaped portion, and after the hook-shaped portion is embedded, there is a certain distance between the hook-shaped end and 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 portion 2332 , which can ensure that the unlocking portion 2332 is smoothly inserted and limit the horizontal displacement of the assembly plate 21 to a certain extent, thereby improving the connection accuracy.

[0149] The inner wall of the card slot 12 is smooth to reduce the friction when the unlocking part 2332 is inserted and removed. However, in some occasions where stability is extremely high, some tiny grooves or protrusions can be provided on the inner wall of the card slot 12 to cooperate with the anti-slip grooves or protrusions of the unlocking part 2332 to further enhance the stability of the connection. Chamfers are provided on the edge of the card slot 12 to guide the insertion of the buckle, so that the unlocking part 2332 is more easily aligned with the card slot 12 and inserted smoothly.

[0150] There are multiple buckles, which are evenly distributed along the edge of the assembly plate 21 , and the number of the slots 12 is consistent with the number of the buckles, so that the connection between the assembly plate 21 and the air conditioner body 130 is more stable.

[0151] A sealing gasket (not shown in the figure) is arranged around the card slot 12. When the buckle is engaged with the card slot 12, the sealing gasket is compressed, which can effectively prevent dust, air and other impurities from entering from the connection between the assembly plate 21 and the air-conditioning body 130, thereby improving the sealing performance and overall performance of the air-conditioning system 100.

[0152] In this embodiment, the quickly detachable dust detection device 110-1 is connected to the air conditioner body 130 through the buckle structure 233. When installing the quickly detachable dust detection device 110-1, the user first aligns the buckle on the assembly plate 21 with the card slot 12 of the air conditioner body 130 to complete the fixation. When disassembling, pressure is applied to the guide slope 2333 to cause the unlocking part 2332 to be elastically deformed, so that the buckle is deformed and escapes from the card slot 12, and the quickly detachable dust detection device 110-1 is disassembled. This structure is convenient and quick to disassemble the quickly detachable dust detection device 110-1, and is convenient for the replacement and cleaning of the quickly detachable dust detection device 110-1.

[0153] In order to enable the quickly detachable dust detection device 110-1 to be quickly installed and disassembled, according to an embodiment of the present application, Fig.28 As shown, the positioning component 23 is a magnetic positioning component 232, which includes a first magnetic sheet arranged on the air-conditioning body 130 of the air-conditioning system 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 magnetically engaged to provide for the positioning and fixation of the assembly plate 21 on the air-conditioning body 130.

[0154] There are multiple first magnetic sheets and second magnetic sheets, and each second magnetic sheet is arranged on the inner side wall of the edge of the assembly plate 21, and is evenly distributed or arranged according to the structural characteristics of the assembly plate 21; the first magnetic sheets are distributed correspondingly along the positions of the edges of the assembly plate 21 on the air-conditioning body 130, ensuring 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 displacement when the air-conditioning system 100 is running.

[0155] The quickly disassembled dust detection device 110-1 also includes a positioning guide plate 2321, which is disposed on the air conditioner body 130. The positioning guide plate 2321 contacts the edge of the assembly plate 21 to guide the first magnetic sheet and the second magnetic sheet to snap into position.

[0156] The first magnetic attraction piece is a permanent magnet, the second magnetic attraction piece is a magnetic attraction fitting that produces magnetic attraction with the first magnetic attraction piece, the permanent magnet is a neodymium iron boron permanent magnet, and the magnetic attraction fitting is a component made of iron, cobalt, nickel and their alloys.

[0157] The first magnetic sheet is a columnar structure, and its cross section is circular, square or polygonal, and the second magnetic sheet has a shape and size that matches the first magnetic sheet. In some embodiments, the first magnetic sheet and the second magnetic sheet have different shapes.

[0158] 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. On the other hand, the notch 11 provides a convenient force application point for the user when installing and disassembling the quickly detachable dust detection device 110-1. The user can more easily grab and move the assembly plate 21 through the notch 11, especially when disassembling, it is convenient to apply an external force to separate the assembly plate 21 from the air conditioner body 130. In some embodiments, the notch 11 is set on the air conditioner body 130, and here, the shape and setting position of the notch 11 are not limited.
