Description

Technical Field

[0001] The present invention relates to the technical field of intelligent doors and windows, and particularly to a system capable of intelligently detecting and automatically replacing filters. Background Art

[0002] With the aggravation of air fine particulate matter pollution, the deficiencies of traditional filter systems in terms of intelligence have become increasingly prominent. The existing technologies (such as CN216498083U) mainly have three major defects: First, there is a lack of real-time monitoring ability for the actual clogging state of the filter, and key parameters such as particulate matter loading rate and wind speed pressure difference change cannot be accurately obtained; Second, the replacement strategy depends on a fixed cycle or manual judgment, resulting in large fluctuations in filtration efficiency; Finally, there is a lack of intelligent coordination among the components of the system, making it difficult to achieve a continuous and stable purification effect. In response to these problems, the present invention innovatively constructs an intelligent monitoring and automatic replacement system. Through a multi-source perception network composed of a high-precision PM2.5 sensor (±1 μg / m 3 ), a wind speed sensing unit (±0.01 m / s) and a usage duration module, combined with an adaptive decision-making engine based on a fuzzy PID algorithm, real-time monitoring and precise control of the filter state are achieved. The system realizes millisecond-level coordination of each component through a standard CAN bus. When the filter health score is lower than the threshold, the replacement program is automatically triggered to ensure the continuous and stable purification efficiency.

[0003] The Chinese utility model patent with the authorization number CN216498083U provides a mechanism for automatically replacing a dust removal filter for a substation cabinet, including a control device, a frame body and a dust removal filter. The upper part of the frame body is provided with an upper roller shaft, and the lower part of the frame body is provided with a lower roller shaft. The upper roller shaft winds the unused part of multiple layers of dust removal filters. There is a dust removal filter for blocking dust between the upper roller shaft and the lower roller shaft; one end of the dust removal filter is wound and fixed to the lower roller shaft, and the lower roller shaft is connected with a driving motor that drives the lower roller shaft to rotate and pulls the dust removal filter to run in the direction of the lower roller shaft; the control device is provided with a single-chip microcomputer, a motor control circuit and a control panel; the single-chip microcomputer obtains the control instructions input by the user through connection with the control panel, and controls the driving motor to run through the motor control circuit to replace the dust removal filter between the upper roller shaft and the lower roller shaft. The present utility model achieves the purpose of automatic replacement, and realizes that when the dust removal filter screen is full of dust or has a large amount of dust accumulation, it can be automatically replaced.

[0004] However, the above-mentioned patent, a mechanism for automatically replacing a dust removal filter for a substation cabinet, has the problems that it cannot intelligently monitor the actual usage condition of the filter and replace the filter in a timely manner, and the filter replacement is not convenient. Therefore, a solution is needed to improve this problem. Summary of the Invention

[0005] The object of the present invention is to provide a system capable of intelligently detecting and automatically replacing a filter screen, so as to monitor the filter screen in real time and make it more convenient to replace the filter screen.

[0006] A system capable of intelligently detecting and automatically replacing a filter screen provided by the present invention includes an openable and closable window frame, a fixing component fixed on the openable and closable window frame, and a material changing component detachably fixed on the fixing component. The system further includes a driving component for driving the material changing component to change materials. The material changing component includes a driving shaft and a driven shaft of the same specification fixed on the left and right sides of the fixing component, and a filter screen wound on the driven shaft. One end of the filter screen is fixed on the driving shaft. The fixing component includes a fixing piece and a cooperating piece fixed on the fixing piece, and further includes a spring buckle slidably reset on the fixing piece. A groove corresponding to the spring buckle is provided on the cooperating piece. The fixing piece and the cooperating piece are combined to form a circular groove with the same specification as the driving shaft and the driven shaft.

[0007] With the above technical solution, the filter screen is sleeved on the driven shaft, and the driving component drives the driving shaft to rotate, driving the filter screen to rotate and discharge on the driven shaft, and the other end of the filter screen rotates and winds on the driving shaft. In this way, the filter screen whose service life reaches the limit can be wound on the driving shaft. When all the filter screens are wound on the driving shaft, the spring buckle on the cooperating piece can be pulled outwards, and then the fixing piece can be detached from the cooperating piece. Furthermore, the driving shaft and the driven shaft can be taken off from the cooperating piece, so that the filter screen on the driving shaft can be quickly scrapped or cleaned. In addition, a new filter screen can be sleeved on the driven shaft to quickly replace the filter screen. After replacing the filter screen, the spring buckle can be pulled outwards to fix the fixing piece on the cooperating piece again.

[0008] Optionally, one end of the filter screen is provided with a T-shaped fixing feature, and the driving shaft is provided with a socketing feature corresponding to the fixing feature of the filter screen.

[0009] With the above technical solution, it can be avoided that the filter screen slips during winding, and the T-shaped feature can improve the convenience for the user to replace.

[0010] Optionally, the driving component includes a motor and a power source for supplying energy to the motor, and further includes a small platform for fixing the power source. The motor is fixed on the top of the driving shaft, and the driving shaft of the motor is connected to the driving shaft.

[0011] With the above technical solution, the motor connected to the power source can continuously supply energy to the driving shaft and the driven shaft, and the driving shaft of the motor has the same T-shaped feature as the driving shaft, so that the motor can conveniently drive the driving shaft to rotate.

[0012] Optionally, the power supply of the driving component is connected to a control system based on a dynamic algorithm and a wireless communication module, and the control system based on a dynamic algorithm and the wireless communication module include a light bulb and a PCB control board, and the PCB board is used to control the motor drive.

[0013] By adopting the above technical solution, the control system based on the dynamic algorithm and the PCB control board of the wireless communication module can control the motor drive. When the filter usage time reaches the specified time, the PCB control board can automatically control the motor rotation to rewind the filter and retract the new filter into the working area.

[0014] Optionally, dustproof boxes are provided on both sides of the openable and closable window frame, and the fixing assembly and the driving assembly are arranged in the dustproof box, and hinges for rotation and closure are provided on the sides of the dustproof box.

[0015] By adopting the above technical solution, the filter is placed in the dustproof box, and the dustproof box hinges form a closed space, thereby preventing the non-working filter from being exposed to the air and causing particles in the air to adhere to the non-working filter.

[0016] Optionally, a push buckle is provided on the hinge, and a rebound buckle corresponding to the push buckle is provided in the dustproof box, and a rebound piece is provided at the bottom of the rebound buckle.

[0017] By adopting the above technical solution, the hinge can be fixed on the dust box by pressing the push buckle on the hinge onto the rebound buckle. When a new filter needs to be replaced, the hinge fixed on the dust box can be pressed to press the top of the pressing piece onto the rebound piece at the bottom of the rebound buckle, so that the pressing piece can be popped out of the rebound buckle by the rebound piece, thereby releasing the fixed state of the dust box and the hinge.

[0019] By adopting the above technical solution, when the filter is in use, the wind speed sensor can be used to sense the latest air flow, and the digital display device can display the sensed data on the screen to facilitate observation by users. The sensor battery box can supply power to the wind speed sensor and the digital display device. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Apparently, the described embodiments are only a part rather than all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings as understood by those of ordinary skill in the art to which the present invention pertains. The words such as "including" used herein are intended to mean that the elements or items appearing before this word cover the elements or items listed after this word and their equivalents, without excluding other elements or items.

[0031] An embodiment of the present invention provides a system capable of intelligently detecting and automatically replacing a filter screen, including an openable and closable window frame 8, a fixing component fixed on the openable and closable window frame 8, and a material-changing component detachably fixed on the fixing component. The system further includes a driving component for driving the material-changing component to change materials. The material-changing component includes a pair of same-specification driving shafts 18 and driven shafts 19 fixed on the left and right sides of the fixing component, and a filter screen 1 wound around the driven shaft 19. One end of the filter screen 1 is fixed on the driving shaft 18. The fixing component includes a fixing member 21 and a fitting member 20 fixed on the fixing member 21, and further includes a spring buckle 2 slidably and resiliently arranged on the fixing member 21. A groove corresponding to the spring buckle 2 is provided on the fitting member 20. The fixing member 21 and the fitting member 20 are combined to form a circular groove 5 having the same specification as the driving shaft 18 and the driven shaft 19.

[0032] See Figures 1-9 , when installing the filter screen 1, the filter screen 1 is sleeved on the driven shaft 19. The driving component drives the driving shaft 18 to rotate, driving the filter screen 1 to rotate and discharge on the driven shaft 19, and the other end of the filter screen 1 rotates and winds on the driving shaft 18. The used area of the filter screen 1 can be moved onto the driving shaft 18. In addition, the new filter screen 1 is moved to the frame opening of the openable and closable window frame 8, so that a new filter screen 1 can be automatically replaced at the frame opening of the openable and closable window frame 8. When the filter screen 1 is all wound on the driving shaft 18, the spring buckle 2 on the fitting member 20 can be pulled outwards, and then the fixing member 21 can be detached from the fitting member 20. Further, the driving shaft 18 and the driven shaft 19 can be removed from the fitting member 20, so that the filter screen 1 on the driving shaft 18 can be quickly scrapped or cleaned. In addition, a new filter screen 1 can be sleeved on the driven shaft 19 to quickly replace the filter screen 1. After replacing the filter screen 1, the spring buckle 2 can be pulled outwards, so that the fixing member 21 can be re-fixed on the fitting member 20 while the spring buckle 2 is loosened. A reset member is provided at the bottom of the spring buckle 2, and the spring buckle 2 resets and inserts into the corresponding groove on the fixing member 21.

[0033] In some embodiments, one end of the filter net 1 is provided with a T-shaped fixing feature, and the driving shaft 18 is provided with a socketing feature corresponding to the fixing feature of the filter net 1.

[0034] In fact, the T-shaped feature can prevent the filter net 1 from slipping during rewinding, and the T-shaped feature can improve the convenience for the user to replace. The user can directly insert the T-shaped end of the filter net 1 into the driving shaft 18.

[0035] In some embodiments, the driving assembly includes a motor and a power source 11 for supplying energy to the motor, and further includes a small platform 16 for fixing the power source 11. The motor is fixed on the top of the driving shaft 18, and the driving shaft of the motor is connected to the driving shaft 18.

[0036] In fact, the connection between the motor and the power source 11 can continuously supply energy to the driving shaft 18 and the driven shaft 19, and the driving shaft of the motor has the same T-shaped feature as the driving shaft 18, so that the motor can conveniently drive the driving shaft 18 to rotate.

[0037] In some embodiments, the power source 11 of the driving assembly is connected with a control system based on a dynamic algorithm and a wireless communication module. The control system based on the dynamic algorithm and the wireless communication module include a light bulb 14 and a PCB control board 17. The PCB board is used to control the driving of the motor.

[0038] In fact, the PCB control board 17 of the control system based on the dynamic algorithm and the wireless communication module can control the driving of the motor. When the usage time of the filter net 1 reaches the specified time, the PCB control board 17 can automatically control the rotation of the motor to wind up the filter net 1 and wind up a new filter net 1 to the working area.

[0039] In some embodiments, dust-proof boxes are provided on both sides of the openable and closable window frame 8, and the fixing assembly and the driving assembly are arranged in the dust-proof boxes. The side of the dust-proof box is provided with a rotatable and closable hinge 3.

[0040] In fact, the filter net 1 is placed in the dust-proof box, and the dust-proof box and the hinge 3 form a closed space, so as to prevent the unworking filter net 1 from being exposed to the air and allowing particles in the air to adhere to the filter net 1 that is not in the working state.

[0041] In some embodiments, a pressing buckle 4 is provided on the hinge 3, and a rebounding buckle 6 corresponding to the pressing buckle 4 is provided in the dust-proof box. A return force member is provided at the bottom of the rebounding buckle 6.

[0042] In fact, by pressing the pressing buckle 4 on the hinge 3 against the rebounding buckle 6, the hinge 3 can be fixed on the dust-proof box. When it is necessary to replace the new filter net 1, the pressing member at the top can be pressed against the return member at the bottom of the rebounding buckle 6 by pressing the hinge 3 fixed on the dust-proof box, so that the pressing member can be ejected from the rebounding buckle 6 by the return member, thereby releasing the fixed state between the dust-proof box and the hinge 3.

[0043] In some embodiments, an intelligent monitoring unit integrating multiple types of sensors is provided on the closable window frame. The intelligent monitoring unit integrating multiple types of sensors includes a wind speed sensor 13, a digital display device 12, and a sensor battery box 15 that are interconnected. The wind speed sensor 13 is located on the inner side of the window of the openable and closable window frame 8.

[0044] In fact, when the filter net 1 is in use, the latest air flow can be sensed by the wind speed sensor 13, and the digital display device 12 can display the sensed data on the screen, so as to facilitate the observation by the user. The sensor battery box 15 can supply power to the wind speed sensor 13 and the digital display device 12.

[0045] Although the embodiments of the present invention have been described in detail above, it is obvious to those skilled in the art that various modifications and changes can be made to these embodiments. However, it should be understood that such modifications and changes are all within the scope and spirit of the present invention described in the claims. Moreover, the present invention described herein may have other embodiments and can be implemented or realized in various ways.
