Description

Technical Field

[0001] The present invention relates to the technical field of toilet feces treatment, and in particular to a flushing-free ecological toilet. Background Art

[0002] A toilet refers to a place built by humans specifically for human physiological excretion and placement of excreta. Traditional toilets can be roughly divided into two structures: dry toilets and flush toilets. In rural areas with water shortages, traditional dry toilets are mostly open-air or semi-enclosed structures. The exposure of feces leads to the breeding of mosquitoes and flies and the diffusion of stench, which is particularly serious in summer and threatens the health of residents. Flush toilets, on the other hand, consume a large amount of water resources, making areas with water shortages wasteful. Moreover, water flushing toilets rely on tap water, and the water fee expenditure poses a pressure on rural families. In addition, low water pressure results in incomplete flushing, and repeated flushing further increases the cost. Therefore, in view of the above problems, it is necessary to propose a more hygienic and water-saving flushing-free ecological toilet. Summary of the Invention

[0003] In view of the above deficiencies of the prior art, the present invention provides a flushing-free ecological toilet.

[0004] To achieve the above invention purpose, the technical solution adopted by the present invention is as follows:

A left pedal and a right pedal are respectively provided on both sides of the defecation port. A first switch and a second switch are respectively provided at the bottoms of the left pedal and the right pedal. The first switch and the second switch are electrically connected to a PLC controller. A feces receiving cart is provided at the bottom of the toilet main body. A discharge port cooperating with the feces receiving cart is provided at the bottom of the toilet main body. A discharge door is provided at the discharge port. An inclined U-shaped guide plate is fixed below the defecation port. A superhydrophobic coating is provided on the outer wall of the U-shaped guide plate. A material receiving mechanism is provided below the U-shaped guide plate. The material receiving mechanism is used for collecting the feces falling from the U-shaped guide plate. A feeding mechanism is provided above the material receiving mechanism. The feeding mechanism is used for conveying a covering material covering the feces. The material mechanism is connected to a foot-operated material receiving turning mechanism, and the foot-operated material receiving turning mechanism drives the material receiving mechanism to perform one-way turning.

[0006] Further, the material receiving mechanism includes a material receiving hopper, a rotating cylinder, a driven rotating shaft and a counterweight. The driven rotating shaft is fixed on the toilet main body. The rotating cylinder is installed on the driven rotating shaft and can rotate. The top of the rotating cylinder is fixedly connected to the bottom of the material receiving hopper. A counterweight is fixed at the bottom of the rotating cylinder.

[0007] Further, in the normal state, the counterweight makes the top opening of the feeding hopper face upward.

[0008] Further, the feeding mechanism includes a feeding pipe and a feeding hopper. The top of the feeding pipe is communicated with the bottom of the feeding hopper. The bottom of the feeding pipe is located above the material receiving mechanism. A feeding through hole matching with the feeding pipe is arranged at the top of the toilet main body. A clearance fit is adopted between the feeding through hole and the feeding pipe. At least one vibration motor is fixed on the feeding pipe or the feeding hopper. The vibration motor is electrically connected with the PLC controller.

[0009] Further, a material plate is arranged in the feeding hopper. A plurality of discharging holes are arranged on the material plate. The discharging holes are round holes or strip-shaped holes.

[0010] Further, the foot-operated material receiving and flipping mechanism includes a driven sprocket, a chain, a driving sprocket, a driving rotating shaft, a rotating shaft bracket and a pedal. The driven sprocket is installed on the driven rotating shaft. The driving rotating shaft is installed on the toilet main body through two rotating shaft brackets. One end of the driving rotating shaft is fixedly connected with the pedal. The driving sprocket is fixed on the driving rotating shaft. The driven sprocket is connected with the driving sprocket through the chain.

[0011] Further, a ratchet tooth ring groove is arranged on the driven sprocket. Two ratchet teeth matching with the ratchet tooth ring groove are arranged on the driven rotating shaft. One end of each ratchet tooth is rotatably connected with the driven rotating shaft through a hinged rotating shaft. A return spring or a return spring piece matching with the ratchet tooth is arranged on the driven rotating shaft.

[0012] Further, when the pedal is stepped on to the bottommost position, the material receiving hopper flips 90 degrees.

[0013] Further, a closed movable plank house is arranged at the top of the toilet main body. A toilet door that can be opened and closed is arranged on the front side of the movable plank house.

[0014] Further, two guide rails matching with the feces receiving trolley are arranged at the bottom of the toilet main body.

[0015] The beneficial effects of the present invention are as follows:

[0016] The flushing-free ecological toilet of the present invention can use powder to wrap and collect feces. The covering material is agricultural waste, such as wood chips, sawdust, sandy soil, fine soil, corn stalk powder, corn cob powder, etc. Water is not used in the feces collection process, which saves water and can also consume agricultural waste. The agricultural waste can also adsorb the moisture of the feces, keep the feces dry, reduce the odor of the feces, and facilitate the subsequent use and transfer of the feces. The toilet of the present invention wraps feces with agricultural waste, so that the feces and agricultural waste can ferment together. The collected feces can be used as farmland fertilizer, making the collected feces recyclable.

[0017] A first switch and a second switch are respectively arranged below the left pedal and the right pedal of the present invention. The first switch and the second switch can cooperate with the material receiving mechanism, the material feeding mechanism and the foot-operated material receiving and turning mechanism to realize the wrapped collection of feces. The material receiving mechanism includes a material receiving hopper and a counterweight. The counterweight can keep the top of the material receiving hopper facing upwards all the time, so as to collect the feces falling from the U-shaped guide plate. The material feeding mechanism includes a material feeding pipe, a material feeding hopper, a material plate and a vibration motor. When the second switch triggered in cooperation with the first switch is triggered, the first laying of materials and the second covering of materials for the material receiving hopper are realized, so as to wrap the feces. The foot-operated material receiving and turning mechanism includes a pedal, a driving rotating shaft, a driving sprocket, a chain and a driven sprocket. By stepping the pedal to the bottommost position, the pedal drives the driving rotating shaft, the driving sprocket, the chain, the driven sprocket and the driven rotating shaft in sequence, so as to drive the material receiving hopper and the collected feces to rotate by 90 degrees, and then pour the material receiving hopper and the feces into the feces receiving trolley to complete the feces collection operation.

[0018] When in use of the present invention, when the user squats on the left pedal and the right pedal with both feet respectively, when both the left pedal and the right pedal are stepped down, the left pedal and the right pedal trigger the first switch and the second switch. At this time, the PLC controller controls the vibration motor to perform the first material feeding operation, sending the covering of the material feeding hopper into the material feeding hopper to lay the covering for the material feeding hopper. When the user finishes using the toilet and lifts both feet from the left pedal and the right pedal, when the first switch and the second switch change from being triggered simultaneously to not being triggered simultaneously, at this time, the PLC controller controls the vibration motor to perform the second material feeding operation, sending the covering of the material feeding hopper into the material feeding hopper to cover the feces falling into the material feeding hopper. Through the two material feeding operations, the full wrapping of the feces is realized, so as to facilitate the subsequent use and transfer of the feces. Description of the Drawings

[0035] As Figures 1 to 4As shown in the figure, the flushing-free ecological toilet includes a box-shaped toilet main body 1. A defecation port 11 is provided at the top of the toilet main body 1. A left pedal 13 and a right pedal 14 are respectively provided on both sides of the defecation port 11. A first switch 15 and a second switch 16 are respectively provided at the bottoms of the left pedal 13 and the right pedal 14. The first switch 15 and the second switch 16 are electrically connected to a PLC controller. A feces receiving trolley 5 is provided at the bottom of the toilet main body 1. Two guide rails 6 that cooperate with the feces receiving trolley 5 are provided at the bottom of the toilet main body 1, so as to facilitate the movement and pushing out of the feces receiving trolley 5. An outlet 17 that cooperates with the feces receiving trolley 5 is provided at the bottom of the toilet main body 1. An outlet door 18 is provided at the outlet 17. The outlet door 18 adopts a double-door structure. A handle and a door switch are provided on the outlet door 18. An inclined U-shaped guide plate 12 is fixed below the defecation port 11. The width of the defecation port 11 is smaller than the width of the U-shaped guide plate 12, so that the U-shaped guide plate 12 can cover the defecation port 11. The cross-section of the U-shaped guide plate 12 is U-shaped, and the concave surface of the U-shaped guide plate 12 faces upward. A superhydrophobic coating is provided on the outer wall of the U-shaped guide plate 12. The superhydrophobic coating enables the surface of the U-shaped guide plate 12 to have a good guiding effect on feces, avoiding feces from sticking to the U-shaped guide plate 12. A material receiving mechanism 2 is provided below the U-shaped guide plate 12. The material receiving mechanism 2 is used to collect the feces falling from the U-shaped guide plate 12. A feeding mechanism 3 is provided above the material receiving mechanism 2. The feeding mechanism 3 is used to convey the covering material covering the feces. The material mechanism 2 is connected to a foot-operated material receiving turning mechanism 4. The foot-operated material receiving turning mechanism 4 drives the material receiving mechanism 2 to perform one-way turning. The present invention can be powered by 220v or by solar energy and storage batteries.

[0036] As Figure 6 shown, the material receiving mechanism 2 includes a material receiving hopper 21, a rotating cylinder 22, a driven rotating shaft 23 and a counterweight 24. Superhydrophobic coatings are also provided on the inner wall and the outer wall of the material receiving hopper 21. The driven rotating shaft 23 is fixed on the toilet main body 1. The rotating cylinder 22 is installed on the driven rotating shaft 23 and can rotate. The top of the rotating cylinder 22 is fixedly connected to the bottom of the material receiving hopper 21. A counterweight 24 is fixed at the bottom of the rotating cylinder 22. The counterweight 24 is arranged on the side opposite to the material receiving hopper 21. Specifically, in the normal state, the counterweight 24 makes the material receiving hopper 21 in the top balance position, so that the top opening of the feeding hopper 32 faces upward.

[0037] As Figure 5As shown in the figure, the feeding mechanism 3 is used to store and convey the covering material. The covering material is used to wrap the feces, which is convenient for the collection of feces. The covering material can be wood chips, sawdust, sand, fine soil, corn stalk powder, corn cob powder, etc. The average diameter of the covering material should be less than 1 mm, so that the covering material has a better wrapping effect on the feces. The feeding mechanism 3 includes a feeding pipe 31 and a feeding hopper 32. The top of the feeding pipe 31 is communicated with the bottom of the feeding hopper 32. The bottom of the feeding pipe 31 is located above the receiving hopper 21 of the receiving mechanism 2. A feeding through hole matching with the feeding pipe 31 is arranged at the top of the toilet main body 1. A clearance fit is adopted between the feeding through hole and the feeding pipe 31. At least one vibration motor 35 is fixed on the feeding pipe 31 or the feeding hopper 32. The vibration motor 35 is electrically connected with the PLC controller. A material plate 33 is arranged in the feeding hopper 32. A number of discharging holes 34 are arranged on the material plate 33. The discharging holes 34 are round holes or strip-shaped holes. The material plate 33 plays a role similar to a filter screen. Under normal conditions, the covering material above the material plate 33 will not fall. When the feeding pipe 31 and the feeding hopper 32 vibrate in cooperation with the vibration motor 35, the covering material above the material plate 33 will fall due to vibration, so as to discharge the covering material in the feeding hopper 32 from the feeding pipe 31. The feeding hopper 32 is installed on the toilet main body 1 through a hopper support 37. The hopper support 37 includes a support plate fixed on the toilet main body 1 and a sleeve for installing the feeding hopper 32. A rubber layer is arranged between the sleeve and the feeding hopper 32, so as to cooperate with the vibration of the feeding hopper 32 to realize the feeding operation of the feeding hopper 32. There is a hopper cover 36 at the top of the feeding hopper 32. The hopper cover 36 is fixed on the top of the feeding hopper 32 in a detachable flip or plug-in form, which is convenient for adding the covering material through the top of the feeding hopper 32.

[0038] As Figure 7 shown, the foot-operated receiving and flipping mechanism 4 includes a driven sprocket 41, a chain 42, a driving sprocket 43, a driving rotating shaft 44, a rotating shaft support 45 and a pedal 46. The driven sprocket 41 is installed on the driven rotating shaft 23. The driving rotating shaft 44 is installed on the toilet main body 1 through two rotating shaft supports 45. One end of the driving rotating shaft 44 is fixedly connected with the pedal 46. The driving sprocket 43 is fixed on the driving rotating shaft 44. The driven sprocket 41 and the driving sprocket 43 are connected by a chain 42. A ratchet tooth ring groove 411 is arranged on the driven sprocket 41. Two ratchet teeth 231 matching with the ratchet tooth ring groove 411 are arranged on the driven rotating shaft 23. One end of each ratchet tooth 231 is rotatably connected with the driven rotating shaft 23 through a hinge rotating shaft 233. A return spring 232 or a return spring piece matching with the ratchet tooth 231 is arranged on the driven rotating shaft 23. Specifically, when the pedal 46 is stepped on to the bottommost position, the receiving hopper 21 flips 90 degrees. When the pedal 46 is stepped on, the driven sprocket 41 drives the driven rotating shaft 23 to rotate. The diameter of the driving sprocket 43 is smaller than that of the driven sprocket 41. The tooth number ratio of the driving sprocket 43 to the driven sprocket 41 is less than or equal to 0.5.

[0039] AsFigure 8 and 9 As shown in 9 , a closed movable shed 7 is provided at the top of the toilet main body 1. A closed space is formed between the top of the toilet main body 1 and the movable shed 7. A toilet door 71 that can be opened and closed is provided on the front side of the movable shed 7, and the toilet door 71 facilitates the entry and exit of users. A staircase 8 is provided at the toilet door 71 to facilitate the entry and exit of users.

[0040] In this embodiment, a crusher is provided at the top of the feeding hopper 32. The crusher can adopt the Xinada crusher s260. Through the crusher, materials such as wooden blocks, corn stalks, and corn cobs can be directly crushed and refined for use in covering feces. A visual transparent opening can also be provided on one side of the feeding hopper 32 to facilitate observing the capacity of the covering material in the feeding hopper.

[0041] Working process and principle:

[0042] S1. During use, when the user squats on the left pedal 13 and the right pedal 14 respectively, when both the left pedal 13 and the right pedal 14 are stepped on, the left pedal 13 and the right pedal 14 trigger the first switch 15 and the second switch 16. At this time, the PLC controller controls the vibration motor 35 to perform the first feeding operation, sending the covering material of the feeding hopper 32 into the feeding hopper 32 to lay the covering material on the feeding hopper 32;

[0043] S2. During the use process, feces fall from the U-shaped guide plate 12 into the receiving hopper 21, and the covering material in the feeding hopper 32 collects the feces;

[0044] S3. When the user finishes using the toilet and lifts their feet from the left pedal 13 and the right pedal 14, when the first switch 15 and the second switch 16 change from being triggered simultaneously to not being triggered simultaneously, at this time, the PLC controller controls the vibration motor 35 to perform the second feeding operation, sending the covering material of the feeding hopper 32 into the feeding hopper 32 to cover the feces that have fallen into the feeding hopper 32;

[0045] S4. After the user finishes using the toilet, by stepping on the pedal 46 to the bottommost position, the pedal 46 drives the driving sprocket 43 to rotate through the driving rotating shaft 44. The driving sprocket 43 drives the driven sprocket 41 to rotate through the chain 42. The driven sprocket 41 drives the driving rotating shaft 44 to rotate through the one-way ratchet cooperation of the ratchet tooth ring groove 411 and the ratchet tooth 231. The driving rotating shaft 44 thus drives the receiving hopper 21 and the counterweight 24 to rotate. When the pedal 46 is at the bottommost position, it drives the receiving hopper 21 to rotate 90 degrees. Since the receiving hopper 21 is in the shape of an inverted isosceles trapezoid, the receiving hopper 21 that rotates 90 degrees pours out the feces and the covering material together, pouring the feces wrapped with the covering material into the feces receiving cart 5;

[0046] S5. After the user lifts the leg from the pedal 46, under the action of the counterweight 24, since the ratchet tooth ring groove 411 of the driven sprocket 41 cannot be engaged with the ratchet tooth 231, the receiving hopper 21 returns to the position where it is vertically upward, so as to perform the next feces collection operation;

[0047] S6. After a certain amount of feces is collected in the feces receiving trolley 5, open the discharge door 18, pull out the feces receiving trolley 5, and the feces receiving trolley 5 can be used for fertilization or centrally transferred to the next link.
