[0030] To further understand the content of the present utility model, the present utility model will be described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present utility model and not for limiting it.

[0031] The following will Figures 1-5 make a further detailed description of this embodiment.

[0032] As Figures 1-4As shown in the figure, an automatically anti-overflow floor drain with intelligent control in this embodiment includes a floor body 100 and a sewer pipe body 110. A groove 301 is formed on the floor body 100. An installation plate 120 is fixedly installed in the groove 301 through an installation component. The installation plate 120 is provided with a water inlet hole communicating with the sewer pipe body 110. A rotating cylinder 210 which is rotatable and extends into the sewer pipe body 110 is arranged on the lower end surface of the installation plate 120. A plurality of rotating grooves 211 are arranged on the outer side wall of the rotating cylinder 210. A fixed cylinder 220 located inside the rotating cylinder 210 is fixedly arranged on the lower end surface of the installation plate 120. Fixing grooves 222 corresponding to the rotating grooves 211 are arranged on the side wall of the fixed cylinder 220. A driving component is arranged at the lower end of the fixed cylinder 220 for driving the rotating cylinder 210 to rotate so that the rotating grooves 211 communicate with or are misaligned with the corresponding fixing grooves 222; A cleaning component for scraping the inner wall of the fixed cylinder 220 is further arranged in the fixed cylinder 220.

[0033] When this embodiment is actually used, the outer side wall of the fixed cylinder 220 is slidably and hermetically attached to the inner wall of the rotating cylinder 210. Thus, when the installation plate 120 is installed in the groove 301 through the installation component, the rotating cylinder 210 and the fixed cylinder 220 can be better extended into the sewer pipe body 110. Among them, both the rotating cylinder 210 and the fixed cylinder 220 are arranged outside the water inlet hole. At this time, when the sewage on the floor body 100 enters the fixed cylinder 220 through the water inlet hole, the driving component drives the rotating cylinder 210 to rotate, so that the rotating grooves 211 on the rotating cylinder 210 communicate with the corresponding fixing grooves 222. At this time, the sewage in the fixed cylinder 220 can flow from the fixing grooves 222 into the rotating grooves 211, and the sewage flows into the sewer pipe body 110 from the rotating grooves 211. When all the sewage in the fixed cylinder 220 flows into the sewer pipe body 110, the driving component drives the rotating cylinder 210 to rotate again, so that the rotating grooves 211 on the rotating cylinder 210 are misaligned with the fixing grooves 222 on the fixed cylinder 220. At this time, the side wall of the rotating cylinder 210 closes the fixing grooves 222, preferably preventing the odor and bugs in the sewer pipe body 110 from overflowing into the room from this, thereby realizing the automatic anti-overflow of this automatically anti-overflow floor drain with intelligent control;

[0034] An installation ring 200 is fixedly installed on the lower end surface of the installation plate 120. The upper end of the rotating cylinder 210 is rotatably installed in the installation ring 200 through a bearing. Thus, the rotating installation of the rotating cylinder 210 on the lower end surface of the installation plate 120 is realized;

[0035] Among them, the rotating cylinder 210 is driven to rotate by a driving component, so as to realize the opening and closing of the fixing groove 222 by the rotating cylinder 210. Compared with the existing ones, when this intelligent control automatic anti-overflow floor drain is not in use, the fixing groove 222 is closed by the rotating cylinder 210, thus preventing the odor and bugs in the sewer pipe body 110 from entering the room, and the actual use effect is better.

[0036] In actual use of this embodiment, a fixing block 400 extending through the rotating cylinder 210 is fixedly installed at the lower end of the fixing cylinder 220. A fixing cavity 450 with an opening downward is provided in the fixing block 400. The driving component includes a motor 410 installed in the fixing cavity 450. The output shaft of the motor 410 extends out of the fixing cavity 450. A fixing circular plate 420 is fixedly installed at the end of the output shaft of the motor 410. A connecting plate 421 connected to the bottom wall of the rotating cylinder 210 is fixedly installed on the fixing circular plate 420, so that the rotation of the motor 410 can drive the fixing circular plate 420 to rotate, and the rotation of the fixing circular plate 420 can drive the rotating cylinder 210 to rotate through the connecting plate 421, thereby realizing the opening and closing of the fixing groove 222.

[0037] Among them, an intercepting plate 430 for intercepting the motor 410 is fixedly installed at the opening of the fixing cavity 450, thereby realizing the installation of the motor 410 in the fixing cavity 450.

[0038] Among them, a humidity sensor 440 is arranged in the fixing cylinder 220, and a control circuit board electrically connected to the humidity sensor 440 is installed in the fixing cavity 450. When the humidity sensor 440 in the fixing cylinder 220 senses sewage, the humidity sensor 440 sends a signal to the control circuit board, and the control circuit board drives the motor 410. The motor 410 drives the rotating cylinder 210 to rotate, so that the fixing groove 222 is in an open state. When the humidity sensor 440 senses that there is no sewage in the fixing cylinder 220, the humidity sensor 440 sends a signal to the control circuit board, and the control circuit board drives the motor 410. The motor 410 drives the rotating cylinder 210 to rotate, so that the fixing groove 222 is in a closed state, thus preventing the odor and bugs in the sewer pipe body 110 from entering the room. Through the setting of the control circuit board, the humidity sensor 440 and the motor 410, the intelligent control of the rotation of the rotating cylinder 210 is realized.

[0039] Among them, both the motor 410 and the control circuit board are installed in the fixing cavity 450, and the intercepting plate 430 closes the fixing cavity 450, thereby preventing the motor 410 and the control circuit board from contacting the sewage and causing damage. Of course, a power supply for supplying power to the motor and other electrical components is also provided in the fixing cavity.

[0040] Among them, both the control circuit board and the humidity sensor 440 adopt the structures disclosed in the patent with the publication number CN214833320U, which are prior arts and will not be elaborated herein.

[0041] In this embodiment, the cleaning component includes a scraper 230 that is liftably disposed in the fixed cylinder 220, and the fixed cylinder 220 is further provided with a driving member for driving the scraper 230 to lift.

[0042] In this embodiment, the scraper 230 is placed on the bottom wall of the fixed cylinder 220. When the sewage in the fixed cylinder 220 is discharged from the fixed groove 222, the particulate matters in the sewage will adhere to the inner wall of the fixed cylinder 220 and the scraper 230. When there are more particulate matters, it may block the fixed groove 222, thus affecting the actual use. At this time, the mounting plate 120 is removed through the mounting component, and the scraper 230 is driven to move upward by the driving member, so that the scraper 230 moves towards the water inlet hole. At the same time, the side wall of the scraper 230 is in sliding fit with the inner wall of the fixed cylinder 220, so that when the scraper 230 moves, it can scrape the inner wall of the fixed cylinder 220, and scrape the particulate matters on the inner wall of the fixed cylinder 220 to a position close to the water inlet hole, thereby facilitating the staff to clean the particulate matters in the fixed cylinder 220 from the water inlet hole;

[0043] Among them, a through hole for the humidity sensor 440 to extend into the fixed cylinder 220 is provided at the central position of the scraper 230. A guiding inclined surface 231 is circumferentially formed on the upper end surface of the scraper 230 around the through hole. When the fixed groove 222 is opened, the sewage in the fixed cylinder 220 will slide out of the fixed groove 222 along the guiding inclined surface 231, thereby preventing some sewage from accumulating on the scraper 230 and causing the accumulated sewage to be unable to slide out of the fixed groove 222;

[0044] Among them, through the groove 301 opened on the floor body 100, when the mounting plate 120 is installed in the groove 301, the mounting plate 120 is flush with the floor body 100, so that the sewage on the floor body 100 can flow into the mounting plate 120 and then flow into the fixed cylinder 220 through the water inlet hole on the mounting plate 120;

[0045] Among them, the mounting plate 120 can be installed in the groove 301 through the mounting component, which makes the installation of the mounting plate 120 in the groove 301 more convenient. At the same time, the installation of the mounting plate 120 in the groove 301 can be released through the mounting component, so that the mounting plate 120 can be taken out of the groove 301. Then, the particulate matters on the surface of the rotating cylinder 210 can be rinsed, and the use effect is better;

[0046] During actual use, the staff can remove the installation of the mounting plate 120 in the groove 301 through the installation component. At this time, when the particulate matter in the fixed cylinder 220 is scraped to the water inlet hole by the driving member, the staff can pour out the particulate matter on the upper part of the scraping plate 230 from the water inlet hole, so as to facilitate the staff to rinse and clean the particulate matter on the scraping plate 230, which is more convenient to use.

[0047] As Figures 1-5 shown, in this embodiment, threaded rods 240 that are opposite to each other and thread through the scraping plate 230 are provided on the bottom wall of the fixed cylinder 220. Gear 510 is provided at the upper end of each threaded rod 240. An installation slot 501 is provided on the mounting plate 120 at the water inlet hole.

[0048] The driving member includes a driving plate 520 that is rotatably provided in the installation slot 501. A driving ring 521 is provided on the driving plate 520, one end of which penetrates through the water inlet hole and extends into the fixed cylinder 220. A tooth groove is provided on the side wall of the driving ring 521 along its circumferential direction. The tooth groove is engaged with the two gears 510. The driving plate 520 drives the driving ring 521 to rotate, and the driving ring 521 drives the gear 510 to rotate, so as to realize the rotation of the threaded rod 240 to drive the scraping plate 230 to scrape the side wall of the fixed cylinder 220.

[0049] In this embodiment, through the settings of the threaded rod 240, the gear 510, the installation slot 501, the driving plate 520, the driving ring 521 and the tooth groove, the gear 510 is fixedly installed on the threaded rod 240, and the driving ring 521 is fixedly installed on the driving plate 520. When the driving plate 520 rotates, it can drive the driving ring 521 to rotate. The rotation of the driving ring 521 can drive the gear 510 to rotate through the tooth groove, and the rotation of the gear 510 can drive the threaded rod 240 to rotate. At this time, the scraping plate 230 is in threaded cooperation with the threaded rod 240, so as to realize the lifting of the scraping plate 230 in the fixed cylinder 220 and scrape the particulate matter on the side wall of the fixed cylinder 220.

[0050] Among them, through the setting of the installation slot 501, when the driving plate 520 is installed in the installation slot 501, the upper end surface of the driving plate 520 is flush with the upper end surface of the mounting plate 120, so as to prevent the driving plate 520 from protruding above the mounting plate 120 and affecting the sewage on the mounting plate 120 from entering the water inlet hole.

[0051] Wherein, a fixing plate 530 which is opposite and into which the upper end of the corresponding threaded rod 240 is inserted is fixedly installed at the upper end of the fixing cylinder 220. The other end of the threaded rod 240 is installed on the bottom wall of the fixing cylinder 220 through a bearing seat, realizing the rotational installation of the threaded rod 240 in the fixing cylinder 220, so that both ends of the threaded rod 240 can be installed in the fixing cylinder 220, making the threaded rod 240 more stable when rotating. At the same time, the two threaded rods 240 are located on both sides of the scraping plate 230 and can limit the scraping plate 230, thereby preventing the scraping plate 230 from rotating along the circumference of the threaded rod 240 when the threaded rod 240 rotates;

[0052] During its actual use, a filter plate 130 for filtering sewage is installed with internal threads in the water inlet hole. The filter plate 130 filters the sewage entering the fixing cylinder 220 and intercepts larger particulate matters in the sewage, thereby preventing larger particulate matters from entering the fixing cylinder 220 from the water inlet and causing blockage of the fixing cylinder 220. When the staff cleans the particulate matters on the scraping plate 230, the filter plate 130 needs to be disassembled from the water inlet hole.

[0053] As Figures 1-3 shown, in this embodiment, insertion holes 302 are formed on the opposite side walls of the groove 301, installation cavities 303 are formed on the opposite side walls of the installation plate 120, and blocking rings 310 are provided at the openings of the installation cavities 303;

[0054] The installation component includes a moving plate 320 arranged in the installation cavity 303. A plug rod 340 with one end passing through the blocking ring 310 and extending outside the installation cavity 303 is arranged on the moving plate 320. A spring 330 is also arranged in the installation cavity 303. The spring 330 is used to push the moving plate 320 towards the blocking ring 310, and one end of the plug rod 340 is inserted into the corresponding insertion hole 302 to realize the installation of the installation plate 120 in the groove 301.

[0055] In this embodiment, through the settings of the insertion hole 302, the installation cavity 303, the blocking ring 310, the moving plate 320, the plug rod 340 and the spring 330, by fixedly installing the plug rod 340 on the moving plate 320, threading the blocking ring 310 in the installation cavity 303, and blocking the moving plate 320 in the installation cavity 303. At the same time, the spring 330 can also be installed in the installation cavity 303. The spring 330 is used to push the moving plate 320 to move, and when the plug rod 340 on the moving plate 320 is always inserted into the insertion hole 302, the installation of the installation plate 120 in the groove 301 is realized;

[0056] Among them, an installation groove 304 communicating with the installation cavity 303 is formed in the upper end surface of the installation plate 120 along its length direction. A moving rod 321 with one end extending out of the installation groove 304 is fixed on the moving plate 320. Push plates 322 are fixedly installed on the extending ends of the moving rods 321. By moving the push plates 322, the staff can drive the moving rods 321 to move along the installation groove 304, so as to move the moving plate 320, slide the insertion rod 340 out of the corresponding insertion hole 302, and thus release the installation of the installation plate 120 in the groove 301. At this time, the staff can take out the installation plate 120 from the groove 301 and clean the outer wall of the rotating cylinder 210;

[0057] During actual use, when the insertion rod 340 is inserted into the corresponding insertion hole 302, the push plate 322 blocks the installation groove 304, so as to prevent sewage from flowing into the installation cavity 303 from the installation groove 304 and affecting the actual use.

[0058] Working principle: First, when the sewage on the floor body 100 enters the fixed cylinder 220 through the water inlet hole, when the humidity sensor 440 in the fixed cylinder 220 senses that there is sewage in the fixed cylinder 220, the humidity sensor 440 sends a signal to the control circuit board, and the control circuit board drives the driving motor 410. The driving motor 410 drives the rotating cylinder 210 to rotate, so that the fixed groove 222 is in an open state, and the sewage in the fixed cylinder 220 can flow into the sewage pipe body 110. When the humidity sensor 440 senses that there is no sewage in the fixed cylinder 220, the humidity sensor 440 sends a signal to the control circuit board, and the control circuit board drives the driving motor 410. The driving motor 410 drives the rotating cylinder 210 to rotate, so that the fixed groove 222 is in a closed state, which can prevent the odor and bugs in the sewage pipe body 110 from entering the room. When the staff needs to clean the outer wall of the rotating cylinder 210 and the particulate matter in the fixed cylinder 220, the staff moves the push plate 322 to slide the insertion rod 340 out of the insertion hole 302, so that the installation plate 120 is taken out of the groove 301. Then, the filter plate 130 is disassembled from the water inlet hole, and the driving ring 521 is driven to rotate by the driving plate 520. The rotation of the driving ring 521 can drive the gear 510 to rotate through the tooth groove, and the rotation of the gear 510 can drive the threaded rod 240 to rotate. At this time, the scraping plate 230 sweeps the particulate matter on the inner wall of the fixed cylinder 220 to the water inlet hole. At this time, the staff can clean and pour out the particulate matter in the fixed cylinder 220. Finally, the outer wall of the rotating cylinder 210 can be cleaned.
