[0046] The use steps of the present invention are as follows: when the integrated filter is used for automatic detection and cleaning, sewage is put into the tank body 1 from the water inlet 7, the sewage will flow through the surface of the filter barrel 302, the filtered sewage will enter the filter barrel 302, and the filtered sewage can be obtained from the water outlet 8. When it is detected that the filtering capacity of the filter barrel 302 is insufficient and needs to be cleaned, the water pump 402 is started to extract part of the filtered sewage from the water outlet 8 through the connection of the water pump 403. The water flow will be drawn into the first connecting pipe 404 for circulation through the operation of the water pump 402. The water flow in the first connecting pipe 404 will flow into the connecting pipe 306, and pass through the second bellows 305, the sliding rod 304, the first output pipe 308, and the second output pipe 310 and the water spray cover 311, water can be evenly sprayed out from the inner wall of the filter barrel 302 at the back-blowing cover 312 position. When the back-blowing cover 312 sprays water and back-blown, the debris attached to the surface of the filter barrel 302 can be blown out. The sewage pump 204 is started to generate suction from the inside of the sewage collecting cover 501 through the connection between the sewage pipe 203 and the first bellows 202. The debris blown out from the back-blowing cover 312 position will enter the inside of the sewage collecting cover 501, and the impurities entering the inside of the sewage collecting cover 501 will be sucked away with the water flow. The sucked-away impurities are discharged from the sewage outlet 205 position, completing the cleaning of the filter barrel 302. While cleaning, the coordinated operation of the first solenoid valve 413 and the second solenoid valve 414 can achieve the effect of The purpose of the movable piston 410 moving up and down continuously is that when the piston 410 moves up, the lifting rod 504 can be driven to move up through the connection between the driving rod 409 and the movable plate 411, and the lifting rod 504 can drive the dirt collecting cover 501 to move up through the connection between the lifting plate 503 and the top rod 502. When the lifting plate 503 is displaced, it can drive the sliding rod 304 to move up. When the sliding rod 304 moves up, it can drive the back-blowing cover 312 to move up through the connection between the first output pipe 308, the connecting ring 309, the second output pipe 310 and the water spray cover 311. Therefore, as the piston 410 moves up and down, the back-blowing cover 312 and the dirt collecting cover 501 can be driven to move up and down synchronously, and the back-blowing cover 312 and the dirt collecting cover 501 can cover the filter barrel 302 to move up and down. , to achieve comprehensive cleaning of the filter barrel 302. During the up and down movement of the dirt collecting cover 501 and the back-blowing cover 312, when the back-blowing cover 312 is displaced, the deformation of the second bellows 305 is utilized to ensure that the back-blowing cover 312 always remains in a connected state. When the dirt collecting cover 501 is displaced, the deformation of the first bellows 202 is utilized to ensure that the dirt collecting cover 501 always remains in a connected state. During the cleaning process, water continues to flow into the water inlet 7 position, and only a small part of the back-blowing cover 312 and the dirt collecting cover 501 are blocking the inner and outer walls of the filter barrel 302, which does not affect the normal filtering work of the filter barrel 302, thereby achieving the purpose of cleaning the filter barrel 302 when the filter is in normal use, effectively improving the use efficiency of the filter and the convenience of maintenance work.

[0047] Example 2: Figure 3 and Figure 10As shown, two fixed rods 901 are fixedly connected at the top of the partition plate 201, a support 905 is fixedly connected at the top of the top cover 6, a sliding plate 902 is slidingly connected between the outer surfaces of the two fixed rods 901, the floating plate 903 is fixedly connected at the top of the sliding plate 902, the detection rod 904 is fixedly connected at the top of the floating plate 903, the upper end surface of the detection rod 904 slidingly penetrates the top cover 6 and extends to the upper side, the distance sensor 906 is fixedly connected at the inner top of the support 905, and the distance sensor 906 is positionally matched with the detection rod 904.

[0048] The detection component 9 is used to monitor the water depth in the tank body 1 in real time, so that whether the filtering efficiency of the filter barrel 302 is abnormal can be detected, that is, the working state of the filter is detected.

[0049] Embodiment three: as shown in Figure 3 , Figure 5 and Figure 9 As shown, the inner surface of the dirt collecting cover 501 is attached to the outer surface of the filter barrel 302, the height of the dirt collecting cover 501 is consistent with that of the backwashing cover 312, and a plurality of comb teeth 505 are fixedly connected to the inner surface of the dirt collecting cover 501.

[0050] When the dirt collecting cover 501 moves up and down, the comb teeth 505 can enter the gaps of the filter barrel 302 and scrape off the stubborn impurities in the gaps, so that the cleaning effect of the filter barrel 302 is good.

[0051] The effect and working principle achieved by the entire mechanism are as follows: when the integrated filter is automatically detected and cleaned, sewage is put into the tank body 1 from the water inlet 7. The interior of the tank body 1 is divided into two parts, the upper and lower parts, by the partition 201, the mounting seat 301, the filter barrel 302 and the sealing plate 303. The sewage enters the upper part from the water outlet 8. At this time, the sewage will flow through the surface of the filter barrel 302, and the impurities in the sewage will be intercepted by the barrier of the filter barrel 302. The filtered sewage will enter the filter barrel 302, and then flow into the lower part of the tank body 1 through the center hole of the partition 201. The filtered sewage can be obtained from the water outlet 8. During the continuous operation of the filter, debris will gradually accumulate on the surface of the filter barrel 302. A large amount of attached debris will cause the filter barrel 302 to 2. The filtration efficiency of the filter element 2 is affected. When the filtration efficiency slows down, the sewage on the upper part of the tank body 1 cannot be filtered out through the filter barrel 302 in time, which will cause water to accumulate above the partition 201. When the accumulated water gradually becomes deeper, the buoyancy of the float plate 903 is utilized to keep the float plate 903 floating on the water surface. Therefore, the float plate 903 and the sliding plate 902 will continue to move upward along the fixed rod 901. The upward movement of the float plate 903 will drive the detection rod 904 to move upward. When the detection rod 904 moves upward, the distance sensor 906 above the detection rod 904 is set. The distance sensor 906 can detect the change in the position of the detection rod 904. Considering that the water injection flow rate of the water inlet 7 will change, when the water injection flow rate suddenly increases, it will cause the product to be produced. Water accumulates, so the state detection of the detection rod 904 is based on distance and time parameters. When the upward movement distance and residence time of the detection rod 904 reach the threshold value, it indicates that the filtering capacity of the filter barrel 302 in the tank body 1 is insufficient, that is, it is in a high liquid level state for a long time, and the filter barrel 302 needs to be cleaned. The depth of water accumulation inside the tank body 1 is monitored in real time by the detection component 9, and whether there is an abnormality in the filtering efficiency of the filter barrel 302 is detected, that is, the purpose of detecting the working state of the filter is achieved. When the detection structure is used, there is only a floating physical structure in the humid environment inside the tank body 1. The floating principle is used to realize the position change of the detection rod 904, and the displacement change of the detection rod 904 is realized by the operation of the distance sensor 906 outside the filter. The distance sensor 906 is in an excessive The outside of the filter has no contact with the filtering environment. Compared with the existing liquid level detection and flow detection, the electronic components of the detection are not affected by the humid environment in the filter, the failure rate is low, and the detection result is more accurate. When it is detected that the filtering capacity of the filter barrel 302 is insufficient and needs to be cleaned, the filter is self-cleaned in the working state through the coordinated operation of the water pump 402, the sewage pump 204, the flow limiting valve 406, the first solenoid valve 413 and the second solenoid valve 414. When the water pump 402 is started, part of the filtered sewage can be extracted from the water outlet 8 through the connection of the water pump 403. At this time, the water flow will be drawn into the first connecting pipe 404 through the operation of the water pump 402 for circulation, and the water flow in the first connecting pipe 404 will flow into the connecting pipe 306.At this time, through the circulation of the second bellows 305, the sliding rod 304, the first output pipe 308, the second output pipe 310 and the water spraying cover 311, water can be evenly sprayed from the inner wall of the filter barrel 302 to the outside from the back-blowing cover 312, that is, the filter barrel 302 is back-blown from the inside to the outside, and the water flow used for back-blowing is the filtered water discharged from the water outlet 8 position. The connection state is formed by the connecting ring 309 and the first output pipe 308, so that there is a large space at the center position to avoid affecting the internal circulation state of the filter barrel 302 during normal use. When the back-blowing cover 312 sprays water for back-blowing, the debris attached to the surface of the filter barrel 302 can be blown out. At the same time, the sewage pump 204 is in the starting state. After the sewage pump 204 is started, suction is generated from the inside of the sewage collecting cover 501 through the connection between the sewage pipe 203 and the first bellows 202. The dirt cover 501 and the back-blowing cover 312 are at the same height and are respectively located at the inner and outer wall positions of the filter barrel 302. Therefore, the debris blown out from the back-blowing cover 312 at this time will enter the interior of the dirt collecting cover 501, and the impurities entering the dirt collecting cover 501 will be sucked away with the water flow, and the sucked-away impurities will be discharged from the sewage outlet 205 position, completing the cleaning of the filter barrel 302. While cleaning, the water flow at the first connecting pipe 404 position will enter the second connecting pipe 405 for diversion. The flow limiting valve 406 is set to limit the water flow of the second connecting pipe 405 to avoid affecting the water pressure of the first connecting pipe 404 and thus affecting the cleaning effect of the back-blowing. The water flow entering the second connecting pipe 405 will flow to the third connecting pipe 407 position. At this time, through the coordinated operation of the first solenoid valve 413 and the second solenoid valve 414, refer to, Figure 8In the middle position state, the two groups of first solenoid valves 413 and second solenoid valves 414 always maintain a state of one flowing and the other closed. When the first solenoid valve 413 at the bottom is opened and the second solenoid valve 414 is closed, water flows into the sleeve 408 from the bottom. Under the action of the water flow, the piston 410 can be pushed up. When the piston 410 moves up to the position between the first solenoid valve 413 and the second solenoid valve 414 at the top, the first solenoid valve 413 at the top is opened and the second solenoid valve 414 is closed. The water flows into the sleeve 408 from the top and can push the piston 410 down. When the piston 410 moves down, the second solenoid valve 414 at the bottom is in an open state. When the second connecting pipe 405 is continuously in the flow state, the first solenoid valve 413 and the second solenoid valve 414 cooperate to operate, which can achieve the purpose of driving the piston 410 to move up and down continuously. When the piston 410 moves up, it can drive the lifting rod 504 to move up through the connection between the driving rod 409 and the moving plate 411. The lifting rod 504 can drive the dirt collecting cover 501 to move up through the connection between the lifting plate 503 and the top rod 502. When the lifting plate 503 is displaced, it can drive the sliding rod 304 to move up. When the sliding rod 304 moves up, it can drive the sliding rod 304 to move up through the first output pipe 308 and the second output pipe 308. The connection between the connecting ring 309, the second output pipe 310 and the water spray cover 311 drives the back-blowing cover 312 to move up, so as the piston 410 moves up and down, the back-blowing cover 312 and the dirt collecting cover 501 can move up and down synchronously, and the back-blowing cover 312 and the dirt collecting cover 501 can cover the filter barrel 302 to move up and down, so as to achieve comprehensive cleaning of the filter barrel 302. In the process of the dirt collecting cover 501 and the back-blowing cover 312 moving up and down, when the back-blowing cover 312 is displaced, the deformation of the second bellows 305 is used to keep the back-blowing cover 312 in a connected state at all times. When the dirt collecting cover 501 is displaced, the deformation of the first bellows 202 is used to keep the dirt collecting cover 501 in a connected state at all times. It always remains connected. During the cleaning process, water continues to flow into the water inlet 7. The inner and outer walls of the filter barrel 302 are only blocked by the backflush cover 312 and a small part of the dirt collecting cover 501, which does not affect the normal filtering work of the filter barrel 302. The purpose of cleaning the filter barrel 302 under normal use of the filter is achieved, and the use efficiency of the filter and the convenience of maintenance work are effectively improved. When the dirt collecting cover 501 moves up and down, the comb teeth 505 on the inner wall of the dirt collecting cover 501 can penetrate into the gap of the filter barrel 302 through the action of the comb teeth 505 on the inner wall of the dirt collecting cover 501, and the more stubborn impurities in the gap are scraped out for cleaning, which has a good cleaning effect on the filter barrel 302.
