[0006] The object of the present invention is to provide an intelligent squat toilet for public toilets, so as to solve the problem of objects falling into the sewer mentioned in the above background technology.

[0007] The technical solution adopted by the present invention is as follows: an intelligent squat toilet for public toilets, comprising a toilet bowl, a base is welded to the side wall of the toilet bowl, and the shape of the base is rectangular; a groove is provided on the squat toilet standing part and the urinal standing part of the base, a pressure switch is installed in the groove, and a pedal is installed at the opening of the groove, and the material of the pedal is rubber or plastic; a flushing port is provided on the rear side of the toilet bowl, and a sewage outlet is provided on the bottom surface of the toilet bowl; symmetrically arranged rotating shafts are rotatably connected on the short side of the toilet bowl, and the number of rotating shafts is two, which are arranged horizontally and It is placed near the long side of the toilet bowl; the shaft end of the rotating shaft extends to the outside of the toilet bowl and is connected to a servo, and the two rotating shafts are controlled by two servos respectively; a cover plate is welded to the side wall of the rotating shaft, and the cover plates on both sides are buckled to form a plane; a pivot is rotatably connected to the long side of the toilet bowl, and there is one pivot, which is horizontally arranged at the center line of the toilet bowl, and the pivot limits the two cover plates to rotate only to form a V shape in the height direction, and a blocking plate is fixed to the side wall of the pivot, and the pivot is located at the center line of the blocking plate to form a seesaw structure, and a counterweight is fixed to the left half of the blocking plate.

[0008] The beneficial effect of adopting the above scheme is: by setting the blocking plate, its initial state is inclined, lower on the left and higher on the right. When the cover plate is opened, the blocking plate is pushed into a horizontal state, forming a trapezoidal groove structure, which can prevent things from falling into the sewer when the user discharges dirt. If personal belongings fall into the toilet bowl, they can be taken out in time. The blocking plate can carry the dirt. After use, the user leaves the pedal and starts flushing. The servo rotates in the opposite direction, and the covers on both sides begin to buckle. As the opening gradually shrinks, the blocking plate tilts, and the dirt is drawn into the sewage outlet. A flat surface is formed behind the cover plate, which can prevent the spread of odor and also prevent items from falling into the sewer.

[0009] Further, the top opening of the toilet bowl is a rounded rectangular cavity, and a conical ring is welded below the opening, and the conical ring is connected to the opening; the middle section of the toilet bowl is a rectangular cavity; the lower part of the toilet bowl is a double-conical cavity, and the lowest section of the double-conical cavity is communicated with the sewage outlet, and the lowest point of the plug plate is located above the demarcation point of the double-conical cavity.

[0010] The beneficial effects of adopting the above further scheme are as follows: by setting the conical ring, it can prevent filth from falling on the rotating shaft; by setting the rectangular cavity, it is convenient for the installation of the cover plate and the plug plate, and can ensure a good sealing effect, with a good anti-odor effect; by setting the double-conical cavity, the dry filth on the plug plate falls into the sewage outlet on the left, and the wet filth on the plug plate falls into the sewage outlet on the right.

[0011] Further, the shape of the cover plate on the left side is Z-shaped, the length of the cover plate is the same as or slightly smaller than the length of the long side of the toilet bowl, the width of the cover plate is greater than half of the length of the short side of the toilet bowl, and the rotating shaft is arranged on the left side of the cover plate; the shape of the cover plate on the right side is flat, the length of the cover plate is the same as or slightly smaller than the length of the long side of the toilet bowl, the width of the cover plate is greater than half of the length of the short side of the toilet bowl, and the rotating shaft is arranged on the right side of the cover plate; after the cover plates are buckled, the cover plate on the right side is embedded in the L-shaped groove of the cover plate on the left side to form a flat surface.

[0012] The beneficial effects of adopting the above further scheme are as follows: by defining the structure and position of the cover plate, a flat surface can be formed, and when the flat surface is horizontal, it fits with the bottom edge of the conical ring on the toilet bowl, realizing the sealing of the toilet bowl.

[0013] Further, through holes are formed on the surface of the plug plate, the through holes are evenly arranged, the size of the through holes is 0.5 - 1 cm, and the through holes are located above the double-conical cavity on the right side of the toilet bowl.

[0014] The beneficial effects of adopting the above further scheme are as follows: by setting the through holes, urine and flushing water fall into the sewage outlet on the right side, while dry filth enters the sewage outlet on the left side under the action of gravity and the thrust of flushing water, realizing the solid-liquid separation of the filth and facilitating the reuse of the filth.

[0015] Further, a limiting plate is fixedly connected to the long side of the toilet bowl, and the limiting plate is located at the lower left position of the plug plate.

[0016] The beneficial effects of adopting the above further scheme are as follows: by setting the limiting plate, after the plug plate is tilted, the lowest point of the plug plate is always located above the demarcation point of the double-conical cavity, and the crosswise arrangement of the plug plate can block the sewage flowing out from the through holes and prevent the sewage from entering the sewage outlet on the left side.

[0017] Further, one end of the pivot is fixedly connected with an anti - reverse head, and the shape of the anti - reverse head is a figure - six shape; the end face of the toilet bowl is fixedly connected with anti - reverse heads arranged oppositely, and the bent arms of the two anti - reverse heads are buckled on the horizontal plane.

[0018] The beneficial effect of adopting the above - mentioned further solution is that by setting the anti - reverse head, the blocking plate can only rotate to the left and cannot rotate to the right.

[0019] Further, a shell is fixedly connected to the long side of the toilet bowl, and the shell slides with the side of the blocking plate. A connecting rod is hinged inside the shell, and the hinge point is located in the left - hand part of the blocking plate and close to the horizontal plane where the blocking plate is located. A compression spring is hinged to the side wall of the connecting rod, the free end of the compression spring is hinged to the toilet bowl, and the free end of the connecting rod is fixedly connected with a push rod. The side wall of the push rod is slidably connected with the upper surface of the blocking plate; a guiding groove is opened on the shell, and the guiding groove plays a guiding role for the sliding of the push rod.

[0020] The beneficial effect of adopting the above - mentioned further solution is that by using the reset function of the compression spring, a thrust for the blocking plate to tilt to the left is generated, ensuring the solid - liquid separation and sewage discharge process.

[0021] Further, a through - slot is opened on the long side of the toilet bowl, and the through - slot is located at the clamping position between the base and the toilet bowl; an air - extraction hood is installed in the through - slot in an in - wedging manner. The shape of the air - extraction hood is a right - angled trapezoid, and the inclined surface of the air - extraction hood is the air inlet; a wind door is hinged on the air inlet, and the position of the wind door is controlled by a traction rope. In the free state, the wind door just blocks the air inlet; the rear end of the air - extraction hood is connected with a photocatalyst air purifier through an air duct. The model of the photocatalyst air purifier is DSG - 100, and the photocatalyst air purifier is connected with a negative - pressure fan through an air duct; the wind door is opened through a rotating cover plate, and a U - shaped groove is opened on the short side of the cover plate.

[0022] The beneficial effect of adopting the above - mentioned further solution is that by setting the wind door, the odor from the sewer can be prevented from directly entering the air - extraction hood; when the negative - pressure fan is started, the odor at the toilet - bowl opening enters the air - extraction hood through the U - shaped groove respectively, and then is discharged from the toilet under the deodorizing and bactericidal effects of the photocatalyst air purifier. In this way, the rising of the odor can be effectively prevented, the use effect is improved, and the wind door is automatically opened as the cover plate rotates, which is more intelligent.

[0023] The beneficial effect of the present invention lies in that: on the basis of being used as a toilet, this application can prevent personal items from falling into the sewer, ensuring people's property safety, and at the same time can avoid the emission of odors.

[0038] As Figure 1 shown, an intelligent squat toilet for public toilets includes a toilet bowl 1, which is welded by stainless steel, facilitating the installation of the components of this application. A base 2 is welded to the side wall of the toilet bowl 1. The base 2 is rectangular in shape. The top surface of the base 2 is flush with or lower than the upper edge of the toilet bowl 1. The flush arrangement is convenient for cleaning work, and the lower arrangement can prevent the user's feet from slipping and stepping into the toilet bowl 1. Grooves 3 are provided at the squatting position part and the urinating position part of the base 2. A pressure switch 4 is installed in the grooves 3, which is used to control the on-off of the electrical appliance. A pedal 5 is installed at the opening of the grooves 3. The pedal 5 is made of rubber or plastic. When the user steps on the pedal 5, it deforms, and the downward pressure triggers the pressure switch 4. By limiting the installation position, it is convenient for both men and women to use. A water flush port 6 is provided on the rear side of the toilet bowl 1. The water flush port 6 is connected to a water pump 8 through a water delivery pipe 7. The water pump 8 is connected to a water storage tank 9 through a water delivery pipe 7. When the water pump 8 is started, the water in the water storage tank 9 is pumped out, and the water flushes the toilet bowl 1 from the rear to the front. A sewage outlet 10 is provided on the bottom surface of the toilet bowl 1. Symmetrically arranged rotating shafts 11 are rotatably connected to the short sides of the toilet bowl 1. The number of the rotating shafts 11 is two, which are horizontally arranged near the long sides of the toilet bowl 1 respectively, to avoid dirt directly falling on the rotating shafts 11. The shaft ends of the rotating shafts 11 extend to the outside of the toilet bowl 1 and are connected to servo motors 12. The two rotating shafts 11 are respectively controlled by two servo motors 12. The number of rotations of the servo motors 12 can control the opening angle of the cover plate 13, and the action sequences of the two servo motors 12 are in sequence, so as to prevent the two side cover plates 13 from colliding when closing. As Figure 2As shown, a cover plate 13 is welded to the side wall of the rotating shaft 11. After the two cover plates 13 are buckled, a plane is formed, which fits with the opening of the toilet bowl 1 to close the opening of the toilet bowl 1, preventing things from falling into the sewer when no one is using the toilet. When the servo 12 drives the cover plate 13 to open, the two cover plates 13 form a V shape, playing a guiding role and forming a barrier in the long side direction of the toilet bowl 1. A pivot 14 is rotatably connected to the long side of the toilet bowl 1. The number of pivots 14 is one, which is horizontally arranged at the midline position of the toilet bowl 1. And the pivot 14 restricts the two cover plates 13 to only rotate to form a V shape in the height direction. A blocking plate 15 is fixedly connected to the side wall of the pivot 14, and the pivot 14 is located at the midline position of the blocking plate 15, forming a seesaw structure. A counterweight 16 is fixedly connected to the left half of the blocking plate 15, making the blocking plate 15 in an inclined state with the left side lower and the right side higher initially, as Figure 7 shown. When the cover plate 13 opens, the blocking plate 15 is pushed into a horizontal state, forming a trapezoidal groove structure, which can prevent things from falling into the sewer when the user discharges filth. If personal items fall into the toilet bowl 1, they can be taken out in time. The blocking plate 15 can carry filth. After use, when the user leaves the pedal 5, the pressure switch 4 automatically returns to its original position and transmits a signal to the controller to inform it that the squat toilet has been used up. The controller controls the water pump 8 to work and starts flushing. The servo 12 rotates in the reverse direction, and the two cover plates 13 start to buckle. As the opening gradually shrinks, the blocking plate 15 inclines, and the filth slides into the sewage outlet 10. And a plane is formed after the cover plate 13, which can prevent the smell from spreading. Based on the toilet, this application can prevent personal items from falling into the sewer, protecting people's property safety, and at the same time can avoid the spread of smell.

[0039] As Figure 3 shown. As an optimization of the embodiment, considering the influence of the above toilet bowl 1 structure on installation, the top opening of the toilet bowl 1 is a rounded rectangular cavity 17, and a conical ring 18 is welded below the opening. The conical ring 18 is connected to the opening, and the conical ring 18 can prevent filth from falling on the rotating shaft 11. The middle section of the toilet bowl 1 is a rectangular cavity 19, which is convenient for the installation of the cover plate 13 and the blocking plate 15, and can ensure a good blocking effect and a good odor prevention effect. The lower part of the toilet bowl 1 is a double-cone-shaped cavity 20. The lowest section of the double-cone-shaped cavity 20 is communicated with the sewage outlet 10. The lowest point of the blocking plate 15 is located above the demarcation point of the double-cone-shaped cavity 20, so that the dry filth on the blocking plate 15 falls into the left sewage outlet 10, and the wet filth on the blocking plate 15 falls into the right sewage outlet 10.

[0040] As Figure 6As shown in the figure, as an optimization of the embodiment, considering the influence of the above-mentioned cover plate 13 structure on odor prevention, the cover plate 13 on the left side is in a Z shape. The length of the cover plate 13 is the same as or slightly smaller than the length of the long side of the toilet bowl 1, and the width of the cover plate 13 is greater than half of the length of the short side of the toilet bowl 1. The rotating shaft 11 is arranged on the left side of the cover plate 13. The cover plate 13 on the right side is in a planar shape. The length of the cover plate 13 is the same as or slightly smaller than the length of the long side of the toilet bowl 1, and the width of the cover plate 13 is greater than half of the length of the short side of the toilet bowl 1. The rotating shaft 11 is arranged on the right side of the cover plate 13. After the cover plates 13 are buckled, the cover plate 13 on the right side is embedded in the L-shaped groove of the cover plate 13 on the left side to form a flat surface. Preferably, the corners of the cover plate 13 are rounded. When this flat surface is horizontal, it fits with the bottom edge of the conical ring 18 on the toilet bowl 1, realizing the closure of the toilet bowl 1.

[0041] As Figure 4 shown in the figure, as an optimization of the embodiment, considering that the present application cannot perform solid-liquid separation and discharge and cannot recycle the filth, through holes 21 are opened on the surface of the blocking plate 15. The through holes 21 are evenly arranged, and the size of the through holes 21 is 0.5 - 1 cm to prevent solids from falling into the right sewage outlet 10 through the through holes 21. The through holes 21 are located above the double-cone-shaped cavity 20 on the right side of the toilet bowl 1. Preferably, the corners of the blocking plate 15 are rounded. The arrangement of the through holes 21 enables urine and flushing water to fall into the right sewage outlet 10, while dry filth enters the left sewage outlet 10 under the action of gravity and the thrust of flushing water, realizing the solid-liquid separation of the filth, facilitating the recycling of the filth. The separated solids can be directly landfilled or used as organic fertilizers for landscaping after harmless treatment, and the separated sewage is discharged into the municipal sewage treatment plant for treatment.

[0042] As Figure 5 shown in the figure, as an optimization of the embodiment, considering that the angle of the above-mentioned blocking plate 15 tilting to the left lacks limitation, if the cover plate 13 is horizontal, the right side of the blocking plate 15 contacts the bottom surface of the cover plate 13, resulting in solids being unable to enter the left sewage outlet 10. A limiting plate 22 is fixedly connected to the long side of the toilet bowl 1. The limiting plate 22 is located at the lower left position of the blocking plate 15. By setting the limiting plate 22, after the blocking plate 15 tilts, the lowest point of the blocking plate 15 is always above the demarcation point of the double-cone-shaped cavity 20, ensuring that solids are guided into the left sewage outlet 10. Moreover, the arrangement of the blocking plate 15 spanning can block the sewage flowing from the through holes 21 and guide the sewage into the right sewage outlet 10.

[0043] As Figure 5As shown, as an optimization of the embodiment, considering that the bearing weight on the right side of the plugging plate 15 is greater than the weight of the counterweight 16, the problem that the plugging plate 15 may tilt to the left may occur, resulting in solid substances entering the right sewage outlet 10. One end of the pivot 14 is fixedly connected with an anti-reverse head 23, and the shape of the anti-reverse head 23 is a figure 6; the end face of the toilet bowl 1 is fixedly connected with anti-reverse heads 23 arranged oppositely, and this anti-reverse head 23 is located on the right side of the previous anti-reverse head 23. The bent arms of the two anti-reverse heads 23 are buckled on the horizontal plane, so that the plugging plate 15 can only rotate to the left and cannot rotate to the right.

[0044] As Figure 5 and 8 shown, as an optimization of the embodiment, considering that the bearing weight on the right side of the plugging plate 15 is greater than the weight of the counterweight 16, the plugging plate 15 may not be able to rotate to the left. A housing 24 is fixedly connected to the long side of the toilet bowl 1, and the housing 24 slides with the side of the plugging plate 15. A connecting rod 25 is hinged in the housing 24, and the hinge point is located on the left side part of the plugging plate 15 and close to the horizontal plane position of the plugging plate 15. A compression spring 26 is hinged to the side wall of the connecting rod 25, and the free end of the compression spring 26 (this point is above the hinge point of the connecting rod 25) is hinged to the toilet bowl 1. The free end of the connecting rod 25 is fixedly connected with a push rod 27, and the side wall of the push rod 27 is slidably connected with the upper surface of the plugging plate 15. Considering the sliding stability of the push rod 27, a guide groove 28 is opened on the housing 24, and the guide groove 28 plays a guiding role in the sliding of the push rod 27. The reset function of the compression spring 26 is used to generate a thrust for the plugging plate 15 to tilt to the left, ensuring the solid-liquid separation and sewage discharge process, and having an anti-reverse function at the same time. Embodiment

[0045] As Figure 9 shown, different from Embodiment 1, considering that the odor generated by the filth will rise during the use of this application, affecting the use effect, a through groove 29 is opened on the long side of the toilet bowl 1, and the through groove 29 is located at the included angle between the base 2 and the toilet bowl 1; a ventilation hood 30 is installed in the through groove 29 in an embedded manner, and the shape of the ventilation hood 30 is a right trapezoid, and the inclined surface of the ventilation hood 30 is an air outlet 31; an air door 32 is hinged on the air outlet 31. Preferably, the corners of the air door 32 are rounded. The air door 32 controls its position through a traction rope 33. In the free state, the air door 32 just blocks the air outlet 31. By setting the air door 32, the odor from the sewer can be prevented from directly entering the ventilation hood 30; the rear end of the ventilation hood 30 is connected with a photocatalyst air purifier 34 through an air pipe 35. The model of the photocatalyst air purifier 34 is DSG-100. The photocatalyst air purifier 34 is connected with a negative pressure fan 36 through an air pipe 35; the air door 32 is pushed open by the rotating cover plate 13, as Figure 10As shown in the figure, further to prevent the cover plate 13 from blocking the air flow, a U-shaped groove 37 is provided on the short side of the cover plate 13. When the user urinates or defecates, the feet will be placed on the pedal 5 and then step on the pressure switch 4. The pressure switch 4 sends information to the controller to inform it that someone is using the squat toilet. The controller controls the negative pressure fan 36 to work, so that the odor at the mouth of the toilet bowl 1 passes through the U-shaped groove 37 into the air extraction hood 30 respectively, and then is discharged from the toilet under the deodorizing and bactericidal effects of the photocatalyst air purifier 34. This can effectively prevent the odor from rising, improve the use effect, and the air damper 32 automatically opens as the cover plate 13 rotates, making it more intelligent.

[0046] Application scenario and working principle: Installing this application in public toilets or tidal toilets can greatly improve the intelligence level of the toilets. When the user urinates or defecates, the feet will be placed on the pedal 5 and then step on the pressure switch 4. The pressure switch 4 sends information to the controller to inform it that someone is using the squat toilet. The controller controls the servo motor 12 to work, and the cover plate 13 starts to rotate. When the cover plate 13 opens, the blocking plate 15 is pushed into a horizontal shape, forming a trapezoidal groove structure. At this time, the user can urinate or defecate (as Figure 7 shown); at the same time, the air damper 32 automatically opens as the cover plate 13 rotates, and the negative pressure fan 36 is started, so that the odor at the mouth of the toilet bowl 1 passes through the U-shaped groove 37 into the air extraction hood 30 respectively, and then is discharged from the toilet under the deodorizing and bactericidal effects of the photocatalyst air purifier 34. This can effectively prevent the odor from rising (as Figure 10 shown); such a structure can prevent things from falling into the sewer when the user discharges filth, and if something is dropped into the toilet bowl 1, it can be taken out in time; after the user leaves the pedal 5 after use, the pressure switch 4 automatically returns to its original position and transmits a signal to the controller to inform it that the squat toilet has been used up. The controller controls the servo motor 12 to work, and the cover plate 13 starts to rotate in the reverse direction. At the same time, flushing starts. The water flow first flushes the filth on the cover plate 13, and the water flow flows down to flush the filth on the blocking plate 15, and the structure of the blocking plate 15 can realize the solid-liquid separation of the filth; as the opening gradually shrinks, the blocking plate 15 tilts, and a flat surface is formed behind the cover plate 13. When this flat surface is horizontal, it fits with the bottom edge of the conical ring 18 on the toilet bowl 1, realizing the sealing of the toilet bowl 1 (as Figure 1 shown); such a structure can prevent odor and prevent items from falling into the sewer, and if something is dropped into the toilet bowl 1, it can be taken out in time. During the use process, only two operations of stepping on the pedal 5 and leaving the pedal 5 are required, so that the cover plate 13 automatically opens, the blocking plate 15 automatically seals, the air damper 32 automatically opens, and the flushing port 6 automatically discharges water, showing the intelligence of this application; on the basis of being used as a toilet, this application can prevent personal items from falling into the sewer, protect people's property safety, and at the same time avoid the spread of odor.
