DETAILED DESCRIPTION

[0050] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0051] Traditional toilets have strong odors, are difficult to clean, are prone to breeding bacteria, and also have serious problems such as waste of water resources.

[0052] The biodegradable toilet of the present application can decompose feces and sewage through the internal decomposition medium. The decomposition medium may include microorganisms and other fillers. Therefore, the decomposition medium can decompose feces and sewage into harmless substances, thereby reducing the pollution of feces and sewage to the surrounding environment. In addition, the biodegradable toilet of the present application does not need to add additional water or other media to decompose feces and sewage, and can achieve water-free treatment, which is conducive to saving water resources.

[0053] For example, the decomposition medium can be a hypersensitive protein complex enzyme. The hypersensitive protein complex enzyme is a complex enzyme in the form of protein, which is chelated from a variety of plant monomer enzymes or plant extracts through a unique secondary low-temperature aerobic fermentation. The hypersensitive protein complex enzyme has a high decomposition efficiency. The hypersensitive protein complex enzyme is stirred and fully contacted with feces and sewage inside the toilet to achieve full decomposition of the feces and sewage.

[0054] The harmless substances formed by the supersensitive protein complex enzyme after decomposing feces can be gas, liquid or solid. Harmless gas can be directly discharged into the surrounding environment. Harmless liquid or solid can be collected and processed.

[0055] It is understandable that sufficient contact between feces and the hypersensitive composite protease can achieve sufficient decomposition of the feces. In the related art, the biodegradable toilet includes a barrel. An agitator is usually provided inside the barrel. The agitator includes a spiral ribbon. Among them, if the size of the spiral ribbon is designed to be larger, the barrel body requires a larger internal space, which is likely to cause the volume of the barrel body to increase, thereby increasing the height of the barrel body and affecting the user's convenience. If the size of the spiral ribbon is designed to be smaller, there is a large gap between the spiral ribbon and the inner wall of the barrel body, which is prone to uneven stirring, resulting in low decomposition efficiency and long time consumption.

[0056] Based on the above technical problems, the applicant has improved the structure of the existing biodegradable toilet. In the embodiment of the present application, the stirring device includes two stirrers arranged side by side in the horizontal direction. On the one hand, the internal space occupied by the stirrers can be reduced while the internal space of the reaction chamber remains unchanged, thereby improving the utilization rate of the internal space of the reaction chamber. On the other hand, the feces and the decomposition medium can be fully stirred and contacted in the reaction chamber, which is conducive to improving the decomposition efficiency.

[0057] The biodegradable toilet of the embodiment of the present application can be applied to public toilets, mobile vehicles, etc. For example, the biodegradable toilet can be applied to rural toilet reform to improve the environmental sanitation of rural toilets.

[0058] The biodegradable toilet provided by the present application is described below with reference to the accompanying drawings and in combination with specific embodiments.

[0059] See also Figures 1 to 3 As shown, the biodegradable toilet 100 of the embodiment of the present application includes a toilet body 110 , a stirring device, a driving device 130 and a control module 140 .

[0060] A reaction chamber 111 is provided in the toilet body 110. The reaction chamber 111 can accommodate a decomposition medium. The reaction chamber 111 has an opening. The decomposition medium and feces can enter the reaction chamber 111 through the opening. The decomposition medium and feces can undergo a decomposition reaction in the reaction chamber 111 to form harmless substances.

[0061] The stirring device is located in the reaction chamber 111. The stirring device may include two stirrers 120 arranged side by side along the horizontal direction X. The stirrer 120 may include a rotating shaft 121 and a screw ribbon assembly 122. The rotating shaft 121 is rotatably connected to the reaction chamber 111. The screw ribbon assembly 122 is sleeved on the outside of the rotating shaft 121. The screw ribbon assembly 122 rotates synchronously with the rotating shaft 121.

[0062] The driving device 130 can drive the stirring device to rotate. For example, the driving device 130 can drive the rotating shafts 121 of the two stirrers 120 to rotate, and the rotating shafts 121 can drive the screw ribbon assembly 122 to rotate synchronously. The screw ribbon assembly 122 can be used to stir the decomposition medium inside the reaction chamber 111 so that the decomposition medium can fully contact the feces. Among them, the two stirrers 120 can rotate in opposite directions.

[0063] The driving device 130 can be electrically connected to the control module 140. The control module 140 can control the start and stop of the driving device 130. When the user uses the biodegradable toilet 100, the control module 140 can control the driving device 130 to start, and the feces and sewage in the reaction chamber 111 begin to be decomposed. When the user uses the biodegradable toilet 100, the control module 140 can control the driving device 130 to stop running. The control module 140 of the embodiment of the present application can realize the intelligence of the biodegradable toilet 100.

[0064] On the premise that the volume of the reaction chamber 111 remains unchanged, by arranging two agitators 120 distributed side by side in the horizontal direction X in the reaction chamber 111, the internal space occupied by the two agitators 120 in the reaction chamber 111 can be effectively reduced, thereby improving the internal space utilization rate of the reaction chamber 111. The interior of the reaction chamber 111 can accommodate more decomposition media and feces to improve the feces decomposition efficiency.

[0065] Specifically, see Figure 4 In the direction shown, along the horizontal direction X, the size of the reaction chamber 111 is M. When one agitator 120 is provided in the reaction chamber 111, the diameter of the ribbon assembly 122 is close to the size of M. When two agitators 120 are provided in the reaction chamber 111, the diameter of one ribbon assembly 122 is approximately M / 2, that is, the size of one ribbon assembly 122 in the vertical direction Z is also M / 2. Since the two agitators 120 are arranged side by side along the horizontal direction X, the size of the internal space of the reaction chamber 111 occupied by the two agitators 120 along the vertical direction Z is still M / 2. Therefore, when two agitators 120 are provided in the reaction chamber 111 along the horizontal direction X, the internal space of the reaction chamber 111 occupied by the stirring device can be reduced.

[0066] In addition, the two agitators 120 rotate in opposite directions in the reaction chamber 111 to improve the fluidity of the internal decomposition medium, and reduce the possibility that when one agitator 120 rotates, the decomposition medium moves to one side in the reaction chamber 111, resulting in local accumulation of the decomposition medium, thereby affecting the decomposition effect. The stirring device of the embodiment of the present application can improve the contact between the feces and the decomposition medium and improve the decomposition efficiency.

[0067] In some examples, the horizontal direction X of the reaction chamber 111 may include a length direction and a width direction. The stirring device may be arranged along the length direction of the reaction chamber 111, that is, the axial direction Y of the rotating shaft 121 may be in the same direction as the length direction of the reaction chamber 111. The two stirrers 120 may be arranged side by side along the width direction of the reaction chamber 111.

[0068] In some possible implementations, see Figure 4As shown, the spiral ribbon assembly 122 of the embodiment of the present application includes a spiral ribbon 1221. Along the axial direction Y of the rotating shaft 121, the spiral ribbon 1221 is arranged outside the rotating shaft 121. The distance t1 between the outer contour of the spiral ribbon 1221 and the inner wall of the reaction chamber 111 is greater than the size of a single particle of the decomposition medium and less than four times the size of a single particle of the decomposition medium.

[0069] It should be noted that the outer contour of the spiral belt 1221 refers to the outer contour of the orthographic projection of the spiral belt 1221 along the axial direction Y of the rotating shaft 121 .

[0070] In some examples, the decomposition medium of the present application can be a hypersensitive protein complex enzyme. The hypersensitive protein complex enzyme can be in a granular form.

[0071] If the distance t1 between the outer contour of the spiral ribbon 1221 and the inner wall of the reaction chamber 111 is too large, it is easy to cause the decomposition medium to accumulate, and part of the decomposition medium cannot be fully utilized. If the distance t1 between the outer contour of the spiral ribbon 1221 and the inner wall of the reaction chamber 111 is too small, it is easy for particles of the decomposition medium to get stuck, and there is even the possibility that the spiral ribbon 1221 collides with the inner wall of the reaction chamber 111 during the rotation of the spiral ribbon 1221, resulting in an operational failure. Therefore, when the distance t1 between the outer contour of the spiral ribbon 1221 and the inner wall of the reaction chamber 111 is greater than the size of a single particle of the decomposition medium, and less than four times the size of a single particle of the decomposition medium, the above problem can be effectively solved.

[0072] Exemplarily, the size of a single particle of the hypersensitive protein complex enzyme may be between 3 mm and 5 mm. In this case, the distance t1 between the outer contour of the spiral ribbon 1221 and the inner wall of the reaction chamber 111 may be 1 cm.

[0073] In some possible implementations, see Figure 4 As shown, in the two agitators 120 of the embodiment of the present application, the distance t2 between the outer contour of the spiral ribbon 1221 of one agitator 120 and the outer contour of the spiral ribbon 1221 of the other agitator 120 is greater than the size of a single particle of the decomposition medium and less than four times the size of a single particle of the decomposition medium.

[0074] Along the axial direction Y of the rotating shaft 121, there is a distance t2 between the outer contour of the orthographic projection of one spiral belt 1221 and the outer contour of the orthographic projection of another spiral belt 1221. If the size of the distance t2 is too large, the decomposition medium is likely to accumulate below the gap, resulting in insufficient utilization of part of the decomposition medium. If the size of the distance t2 is too small, it is likely that the two spiral belts 1221 will collide during operation, resulting in the possibility of operating failure. In the embodiment of the present application, the minimum value of the size of the distance t2 is greater than the size of a single particle of the decomposition medium and less than four times the size of a single particle of the decomposition medium, which can effectively solve the above problems.

[0075] In some possible implementations, see Figures 3 to 5 As shown, the screw belt assembly 122 of the embodiment of the present application further includes an external sleeve 1222. The screw belt 1221 is disposed outside the external sleeve 1222. Along the axial direction Y of the rotating shaft 121, the external sleeve 1222 is sleeved outside the rotating shaft 121. The external sleeve 1222 is detachably connected to the rotating shaft 121.

[0076] The screw belt assembly 122 of the embodiment of the present application can be detachably connected to the rotating shaft 121 through the external sleeve 1222, so it is convenient for staff to install and maintain the screw belt assembly 122.

[0077] For some examples, see Figures 3 to 5 The agitator 120 of the embodiment of the present application shown further includes a plurality of fixing rods 1223. The plurality of fixing rods 1223 can be evenly arranged outside the outer sleeve 1222. The spiral belt 1221 is connected to the outer sleeve 1222 through the fixing rods 1223.

[0078] Exemplarily, the fixing rod 1223 may be welded to the outer sleeve 1222. The screw belt 1221 may be welded to the fixing rod 1223. The outer sleeve 1222, the fixing rod 1223 and the screw belt 1221 may be welded into an integral structure and then detachably connected to the rotating shaft 121.

[0079] In some possible implementations, see Figure 5 As shown, the reaction chamber 111 may include two side walls 1111 disposed opposite to each other along the axial direction Y of the rotating shaft 121. Along the axial direction Y of the rotating shaft 121, both ends of the rotating shaft 121 may be rotatably connected to the reaction chamber 111 via bearings. The screw belt assembly 122 may be located inside the reaction chamber 111. The size of the external sleeve 1222 may be smaller than the distance between the two opposite inner walls of the reaction chamber 111 along the axial direction Y of the rotating shaft 121.

[0080] When the ribbon 1221 is worn out after long-term use, the staff can replace the ribbon assembly 122 without replacing the entire agitator 120, which is conducive to reducing maintenance costs. In addition, when the staff replaces the ribbon assembly 122, the rotating shaft 121 can be taken out of the reaction chamber 111 along the axial direction Y. At this time, the rotating shaft 121 can be separated from the ribbon assembly 122, and the staff can easily remove the ribbon assembly 122, thereby reducing the maintenance difficulty of the staff and improving the maintenance efficiency.

[0081] In some possible implementations, see Figure 3 and Figure 5As shown, a first positioning hole may be provided on the rotating shaft 121 of the embodiment of the present application. A second positioning hole may be provided on the side wall 1111 of the external sleeve 1222. The first positioning hole and the second positioning hole are correspondingly arranged. The agitator 120 may also include a positioning column 123. The positioning column 123 is inserted into the first positioning hole and the second positioning hole. The positioning column 123 can constrain the external sleeve 1222 and the rotating shaft 121 to produce relative movement.

[0082] The positioning column 123 of the embodiment of the present application can be penetrated through the rotating shaft 121 and the external sleeve 1222 along the radial direction of the rotating shaft 121, so as to constrain the external sleeve 1222 and the rotating shaft 121 to move along the axial direction Y through the positioning column 123.

[0083] In some examples, an outer surface of the positioning column 123 near one end may be provided with an external thread along the axial direction of the positioning column 123. The agitator 120 may further include a locking nut 124. The locking of the positioning column 123 and the locking nut 124 may constrain the relative movement of the external sleeve 1222 and the rotating shaft 121 along the radial direction of the rotating shaft 121, which is conducive to improving the connection reliability of the rotating shaft 121 and the screw belt assembly 122.

[0084] For some examples, see Figure 5 As shown, the outer surface of the external sleeve 1222 may be provided with a recess 1222a. The second positioning hole may be provided on the bottom wall of the recess 1222a. When the positioning column 123 and the locking nut 124 are locked with each other, the locking nut 124 may abut against the bottom wall of the recess 1222a. The bottom wall of the recess 1222a may be a planar structure, so that the locking nut 124 may fit with the bottom wall of the recess 1222a, which is beneficial to improve the locking effect, thereby reducing the possibility of loosening between the locking nut 124 and the external sleeve 1222 after the agitator 120 is used for a long time.

[0085] In some examples, there may be multiple positioning posts 123. The axial directions of the multiple positioning posts 123 may form an angle, that is, the axial directions of the multiple positioning posts 123 may be in different directions.

[0086] It is understandable that the number of the positioning posts 123 can match the number of the first positioning holes and the second positioning holes. The positioning posts 123 are arranged correspondingly to the first positioning holes and the second positioning holes.

[0087] In some possible implementations, see Figure 3 As shown, the driving device 130 may be disposed in the reaction chamber 111. The driving device 130 may include a first power unit 131 and a second power unit 132. The first power unit 131 and the second power unit 132 may respectively drive the two agitators 120 to operate.

[0088] The first power unit 131 and the second power unit 132 of the embodiment of the present application can be independent of each other. The control module 140 can control the first power unit 131 to drive one of the agitators 120 to operate, and the control module 140 can also control the second power unit 132 to drive the other agitator 120 to operate.

[0089] It is understandable that if one power unit is used to drive two agitators 120 to operate at the same time, a complex transmission structure is usually required. For example, gear transmission, belt transmission, etc. However, the method of driving two agitators 120 to operate at the same time through gear transmission is likely to lead to a complex structural design, which is prone to failure and is also likely to increase costs. In addition, noise is likely to be generated during the gear transmission process, thereby affecting the user experience. The first power unit 131 and the second power unit 132 of the embodiment of the present application independently control the two agitators 120, which can effectively solve the above problems.

[0090] In some examples, the first power unit 131 and the second power unit 132 may both be motors, and the motors may drive the rotating shaft 121 to rotate via a driving shaft.

[0091] In some possible implementations, see Figure 2 As shown, along the vertical direction Z, the reaction chamber 111 of the embodiment of the present application may have an upward opening. The biodegradable toilet 100 may also include a fan 150 and a guide pipe 160. The fan 150 is electrically connected to the control module 140. The guide pipe 160 is connected to the reaction chamber 111. The fan 150 may be located in the space where the guide pipe 160 is connected to the reaction chamber 111, and the fan 150 is close to the opening of the reaction chamber 111.

[0092] The decomposition medium of the embodiment of the present application can decompose feces into harmless gas and solid. The gas can move upward, so that the harmless gas can be discharged to the outside of the toilet body 110 through the guide pipe 160 by the fan 150.

[0093] In some examples, the control module 140 can control the operation time of the fan 150. During the operation of the stirring device, the decomposition medium can decompose the feces into harmless gas, and the fan 150 can be started to discharge the harmless gas. When the stirring device stops running, the control module 140 can stop the fan 150.

[0094] In some possible implementations, see Figure 2 As shown, the biodegradable toilet 100 of the embodiment of the present application may further include a temperature sensor and a heating plate 180. The heating plate 180 may be disposed on the outer wall of the reaction chamber 111. The temperature sensor may detect the temperature inside the reaction chamber 111 to control the heating plate 180 to be turned on or off.

[0095] The reaction chamber 111 of the embodiment of the present application needs to be maintained at a constant temperature to promote the decomposition of feces by the decomposition medium. Therefore, a preset temperature can be set for the internal temperature of the reaction chamber 111 through the control module 140. The preset temperature can be the temperature at which the decomposition medium has the highest efficiency in decomposing feces. When the temperature sensor detects that the temperature inside the reaction chamber 111 is lower than the preset temperature, a signal can be sent to the control module 140, so that the control module 140 can start the heating plate 180 to heat the reaction chamber 111. When the temperature sensor detects that the temperature inside the reaction chamber 111 reaches the preset temperature, the control module 140 can stop the heating function of the heating plate 180.

[0096] In some examples, the heating plate 180 may be disposed on the bottom wall of the reaction chamber 111. The heating plate 180 may be in contact with the bottom wall of the reaction chamber 111.

[0097] In some examples, the biodegradable toilet 100 of the embodiment of the present application may further include a shielding plate 170. The shielding plate 170 may be a cylindrical structure along the vertical direction Z. The shielding plate 170 has two openings along the vertical direction Z. Feces and sewage may slide into the reaction chamber 111 through the shielding plate 170 through the opening located at the top. The shielding plate 170 may shield part of the stirring device.

[0098] In some possible implementations, see Figure 1 and Figure 2 As shown, the biodegradable toilet 100 of the embodiment of the present application may further include a toilet cover 190 and a position sensor 200. The toilet cover 190 covers the opening of the reaction chamber 111. The position sensor 200 is electrically connected to the control module 140. The position sensor 200 may be disposed on the toilet cover 190.

[0099] The position sensor 200 of the embodiment of the present application can be used to sense the closed state of the toilet lid 190 to determine whether the biodegradable toilet 100 is in an application state. For example, when the toilet lid 190 is in an open state, it means that the biodegradable toilet 100 is in use. The position sensor 200 can transmit a signal to the control module 140, and the control module 140 controls the stirring device to stop running. When the toilet lid 190 is in a closed state, it means that the biodegradable toilet 100 is not occupied. The position sensor 200 can transmit a signal to the control module 140, and the control module 140 can control the stirring device to start, so as to decompose and process the feces in the reaction chamber 111.

[0100] In addition, the position sensor 200 of the embodiment of the present application can also monitor the opening and closing time of the toilet cover 190. It is understandable that the control module 140 can confirm whether the feces and sewage are feces or urine according to the information transmitted by the position sensor 200. If the opening and closing time of the toilet cover 190 is long, the feces and sewage are feces, and the control module 140 can control the operation time of the stirring device to increase so as to fully decompose the feces and sewage through the decomposition medium. Similarly, if the opening and closing time of the toilet cover 190 is short, the feces and sewage are urine, and the control module 140 can control the operation time of the stirring device to decrease.

[0101] In addition, the position sensor 200 of the embodiment of the present application can also monitor the number of times the toilet lid 190 is opened and closed, so as to confirm the amount of feces and sewage according to the number of times the toilet lid 190 is opened and closed, thereby appropriately increasing or decreasing the decomposition time. The more times the toilet lid 190 is opened and closed, the more times the biodegradable toilet 100 is used, and the greater the amount of feces and sewage in the reaction chamber 111, the control module 140 can increase the rotation time of the stirring device to fully decompose the feces and sewage. Similarly, if the toilet lid 190 is opened and closed less times, the biodegradable toilet 100 is used less times, and the amount of feces and sewage in the reaction chamber 111 is also less, the control module 140 can shorten the rotation time of the stirring device.

[0102] For some examples, see Figure 2 As shown, the control module 140, the fan 150, the temperature sensor, the heating plate 180 and the driving device 130 can all be arranged on the outer wall of the reaction chamber 111. The biodegradable toilet 100 of the embodiment of the present application can also include a cover plate 210. The cover plate 210 can be connected to the toilet body 110 to shield the control module 140, the fan 150, the temperature sensor, the heating plate 180 and the driving device 130.

[0103] Exemplarily, the cover plate 210 can be detachably connected to the toilet body 110 to facilitate the maintenance of the control module 140 , the fan 150 , the temperature sensor, the heating plate 180 and the driving device 130 by the staff.

[0104] The working principle of the biodegradable toilet 100 of the embodiment of the present application may be as follows.

[0105] When the toilet lid 190 is closed, the position sensor 200 can transmit a signal to the control module 140. The control module 140 can start the stirring device. The two stirrers 120 of the stirring device can stir the decomposition medium and the feces and sewage uniformly. In addition, the control module 140 can start the fan 150 to operate so as to guide the gas generated by the decomposition of the feces and sewage to the outside of the toilet body 110 through the guide pipe 160.

[0106] The control module 140 can control the operation time of the stirring device according to the opening and closing times and time of the toilet lid 190 transmitted by the position sensor 200. After the feces decomposition process is completed or the toilet lid 190 is opened again, the control module 140 can stop the operation of the stirring device, and the fan 150 also stops moving.
