The second screw is inserted into the first threaded hole and is threadedly connected to both the first threaded hole and the rivet nut 15, that is, the second screw is threadedly connected to the first threaded hole and is threadedly connected to the rivet nut 15. By providing the rivet nut 15, it is easy to install on the inner liner.

[0049] In order to improve the reliability of the connection, the rivet nut 15, the first threaded hole and the second screw are provided in multiple and one-to-one correspondence, that is, each rivet nut 15 corresponds to a first threaded hole and a second screw. Exemplarily, four rivet nuts 15 are provided at the bottom of the inner shell, and the four rivet nuts 15 are distributed in two rows and two columns. Correspondingly, the outer shell is provided with four first threaded holes, and each first threaded hole corresponds to a rivet nut 15. The four second screws are respectively connected to the corresponding first threaded holes and rivet nuts 15, so as to fix the inner shell and the outer shell.

[0050] Continue reading Figures 1 to 4 The inner pot includes a lower shell 10, an upper cover 20, a stirring assembly and a driving assembly, wherein the lower shell 10 has a first accommodating chamber 13 and a first opening communicating with the first accommodating chamber 13. The upper cover 20 is buckled on the first opening and sealedly connected with the lower shell 10. The stirring assembly is arranged in the first accommodating chamber 13 and connected with the driving assembly, and the driving assembly drives the stirring assembly to move. The material of the lower shell 10 can be metal, such as stainless steel, etc., and the material of the upper cover 20 can be plastic.

[0051] Specifically, a first accommodating cavity 13 is formed inside the lower shell 10, and a first opening is formed on the top of the lower shell 10, the first opening is opposite to the first accommodating cavity 13, and is adapted to the upper cover 20. Exemplarily, the lower shell 10 includes a bottom plate 12 and a first side plate 11, and one end of the first side plate 11 is connected to the bottom plate 12. The first side plate 11 and the bottom plate 12 enclose the first accommodating cavity 13, and one end of the first side plate 11 away from the bottom plate 12 encloses the first opening, so that the opening area of ​​the first opening is larger, which is convenient for dirt to pass through.

[0052] Among them, the first side panel 11 and the bottom panel 12 can be integrally formed, and both the first side panel 11 and the bottom panel 12 can be flat panels. The first side panel 11 and the bottom panel 12 are connected by an arc to make a smooth transition between the first side panel 11 and the bottom panel 12. Fillers can also be provided at the bottom of the first accommodating chamber 13 to allow microbial flora to grow, and then react with waste to biodegrade the waste. Four first side panels 11 can be provided, and the four first side panels 11 are connected end to end in sequence, and two first side panels 11 are arranged opposite to each other along a first direction, and two first side panels 11 are arranged opposite to each other along a second direction. The first direction is the width direction of the toilet, such as Figure 1 The X direction is shown, and the second direction is the length direction of the toilet. Figure 1 Y direction shown.

[0053] In some possible examples, the lower shell 10 faces one end of the upper cover 20 ( Figure 2 The top of the upper cover 20 is also provided with a first flange 14. For example, the first flange 14 completely surrounds the first accommodating cavity 13 in the circumferential direction, that is, the first flange 14 surrounds the first accommodating cavity 13 in the entire circumference. Among them, one end of the first flange 14 facing the upper cover 20 is flush with one end of the first side plate 11 facing the upper cover 20. The first flange 14 may be provided with a plurality of second threaded holes arranged circumferentially, and each second threaded hole may be evenly arranged.

[0054] Continue reading Figures 1 to 4 The upper cover 20 has a second accommodating cavity 23, and a second opening and a third opening 24 connected to the second accommodating cavity 23. The second opening and the third opening 24 are respectively on both sides of the second accommodating cavity 23, and the second opening is adjacent to the first opening. Exemplarily, the upper cover 20 includes a top plate 22 and a second side plate 21, and one end of the second side plate 21 is connected to the top plate 22. The second side plate 21 and the top plate 22 enclose the second accommodating cavity 23, and one end of the second side plate 21 away from the top plate 22 encloses the second opening, so that the opening area of ​​the second opening is larger, which is convenient for dirt to pass through. The top plate 22 is provided with a third opening 24, so that dirt can enter the first accommodating cavity 13 through the second accommodating cavity 23.

[0055] The second side plate 21 and the bottom plate 12 may be integrally formed, the top plate 22 may be a flat plate, and the third opening 24 may be circular. The top plate 22 may also be provided with a fourth opening 25 spaced apart from the third opening 24, the fourth opening 25 being used for exhaust, for example, the fourth opening 25 is connected to the exhaust device, and the fourth opening 25 may be rectangular.

[0056] Four second side panels 21 may be provided, and the four second side panels 21 are connected end to end in sequence, and two second side panels 21 are arranged opposite to each other along the first direction, and two second side panels 21 are arranged opposite to each other along the second direction. The two second side panels 21 opposite to each other along the first direction may be flat plates, and the two second side panels 21 opposite to each other along the second direction may be folded plates to match the outer shell.

[0057] In some possible examples, a second flange 26 ( Figure 2 The bottom end shown in the figure), illustratively, the second flange 26 completely surrounds the second accommodating cavity 23 in the circumferential direction, that is, the second flange 26 surrounds the second accommodating cavity 23 in the entire circumference. Among them, the end of the second flange 26 facing the lower shell 10 is flush with the end of the second side plate 21 facing the lower shell 10. The second flange 26 may be provided with a plurality of third threaded holes arranged circumferentially, the third threaded holes are opposite to the second threaded holes, and the third threaded holes may be evenly arranged.

[0058] like Figure 2 and Figure 3 As shown, the lower shell 10 and the upper cover 20 are respectively provided with a first flange 14 and a second flange 26 at one end adjacent to each other, the first flange 14 and the second flange 26 are in contact with each other, and are fixedly connected by a first screw 31. Specifically, the first screw 31 is threadedly connected in the second threaded hole corresponding to the first flange 14, and is threadedly connected in the third threaded hole corresponding to the second flange 26, so as to fix the lower shell 10 and the upper cover 20.

[0059] In this way, the lower shell 10 and the upper cover 20 are detachably connected. By installing or removing the first screw 31, the lower shell 10 and the upper cover 20 can be fixed and separated, which makes it easy to disassemble the lower shell 10 and the upper cover 20 so that their internal structures are exposed and visible, and it is easy to inspect, clean and construct the interior of the lower shell 10 through the larger first opening of the lower shell 10, and to inspect, clean and construct the interior of the upper cover 20 through the larger second opening of the upper cover 20.

[0060] It is understandable that the sealed connection between the lower shell 10 and the upper cover 20 can be achieved by using the first flange 14, the second flange 26 and the first screw 31, and a seal can be provided between the first flange 14 and the second flange 26 to further improve the sealing performance.

[0061] Continue reading Figures 1 to 4The stirring assembly is used to mix the dirt with the filler, and is disposed in the lower shell 10 and connected to the driving assembly. The stirring assembly can be mounted on the lower shell 10, and the lower shell 10 is used to support the stirring assembly. Exemplarily, the stirring assembly includes a rotating shaft 41, and a stirring member 40 fixedly disposed on the rotating shaft 41. The rotating shaft 41 is located in the first accommodating cavity 13 and both ends are mounted on the lower shell 10. The rotating shaft 41 can rotate relative to the outer shell, and the stirring member 40 is located in the first accommodating cavity 13.

[0062] The rotating shaft 41 may be in the shape of a rod, such as a round rod. The rotating shaft 41 is located in the first accommodating chamber 13, and the two ends of the rotating shaft 41 are respectively mounted on two opposite side walls ( Figure 3 Exemplarily, the two ends of the rotating shaft 41 are respectively mounted on two first side plates 11 opposite to each other along the second direction. The rotating shaft 41 can penetrate and extend outward from the lower shell 10.

[0063] The stirring member 40 is fixedly connected to the rotating shaft 41 so as to rotate with the rotating shaft 41 to stir. In some possible implementations, the stirring member 40 includes a spiral ribbon 42 and a connecting rod 43, wherein the spiral ribbon 42 is wound around the rotating shaft 41, and the connecting rod 43 is fixedly connected to the spiral ribbon 42 and the rotating shaft 41, and a sub-plate 44 can also be fixedly connected to the connecting rod 43 to improve the uniformity of stirring.

[0064] The spiral ribbon 42 refers to a ribbon extending in a spiral shape, and the spiral ribbon 42 is wound around the rotating shaft 41 and spaced apart from the rotating shaft 41. One end of the connecting rod 43 is connected to the spiral ribbon 42, and the other end is connected to the rotating shaft 41. For example, one end of the connecting rod 43 is connected to the end of the spiral ribbon 42, and the other end of the connecting rod 43 is connected to the outer peripheral surface of the rotating shaft 41.

[0065] At least two connecting rods 43 may be provided to ensure that the spiral belt 42 is firmly connected to the rotating shaft 41. For example, two connecting rods 43 are provided, and the two connecting rods 43 are respectively connected to the two ends of the spiral belt 42. For another example, a plurality of connecting rods 43 are provided, and two connecting rods 43 of the plurality of connecting rods 43 are respectively connected to the two ends of the spiral belt 42, and the remaining connecting rods 43 are evenly distributed between the two connecting rods 43 at the two ends. Alternatively, the spacing between two adjacent connecting rods 43 of the remaining connecting rods 43 is equal to the pitch of the spiral.

[0066] In order to improve the stirring efficiency, there are at least two spiral ribbons 42, and the ends of at least two spiral ribbons 42 on the same side are symmetrically distributed on the outer periphery of the rotating shaft 41, and a connecting rod 43 is provided between the rotating shaft 41. Specifically, the first ends of at least two spiral ribbons 42 are symmetrically distributed on the outer periphery of one end of the rotating shaft 41, and the second ends of at least two spiral ribbons 42 are symmetrically distributed on the outer periphery of the other end of the rotating shaft 41. Figure 1 As shown, the first end of the spiral ribbon 42 is the left end of the spiral ribbon 42 , and the second end of the spiral ribbon 42 is the right end of the spiral ribbon 42 .

[0067] In some possible examples, the spiral radius and spiral direction of at least two spiral ribbons 42 are the same, and further, the pitch of the two spiral ribbons 42 is the same. Such an arrangement can avoid interference between at least two spiral ribbons 42, and the processing is simple and the stirring effect is good. For example, two spiral ribbons 42 are provided, and the two spiral ribbons 42 are symmetrically distributed on the outer periphery of the rotating shaft 41. Among them, the pitch of the spiral ribbon 42 refers to the axial distance between two adjacent threads on the spiral ribbon 42, the spiral direction of the spiral ribbon 42 includes clockwise and counterclockwise directions, and the spiral radius of the spiral ribbon 42 refers to the horizontal distance from the center of the spiral ribbon 42 to the axis.

[0068] In some other possible examples, at least two spiral ribbons 42 have different spiral radii. In this way, the spiral ribbon 42 with a smaller spiral radius is located on the inner side, and can stir the dirt and filler closer to the rotating shaft 41, and the spiral ribbon 42 with a larger spiral radius is located on the outer side, and can stir the dirt and filler farther from the rotating shaft 41. Such an arrangement can reduce the stirring dead zone and improve the stirring effect. Furthermore, the spiral directions of at least two spiral ribbons 42 are different, so that the stirring directions of at least two spiral ribbons 42 are different, which can further improve the stirring effect.

[0069] like Figure 1 and Figure 3 As shown, two stirring members 40 may be provided, and the two stirring members 40 are arranged in parallel along the first direction to improve the stirring efficiency, that is, the stirring members 40 form a stirring structure of a double-axis spiral ribbon 42. The two stirring members 40 are spaced apart along the first direction to avoid interference in the movement of the two stirring members 40. The structures of the spiral ribbons 42 of the two stirring members 40 may be the same or different, and this is not limited.

[0070] Continue reading Figures 1 to 4 The toilet further includes two transmission assemblies 60 respectively arranged on both sides of the lower shell 10, and the two transmission assemblies 60 are connected to both ends of the rotating shaft 41 and to the driving assembly. The transmission assembly 60 is used to connect the stirring member 40 to the driving assembly and to rotate the stirring member 40 relative to the lower shell 10.

[0071] See also Figure 5 Each driving assembly includes a bearing seat 61, a rolling bearing 62, a first retaining ring 63 and a second retaining ring 64. The bearing seat 61 is arranged on the lower shell 10 and is located outside the first accommodating cavity 13. The rolling bearing 62 is arranged in the bearing seat 61 and can roll relative to the bearing seat 61. The rolling bearing 62 is inserted with a rotating shaft 41, and the rotating shaft 41 moves synchronously with the rolling bearing 62. The first retaining ring 63 and the second retaining ring 64 are respectively arranged on the bearing seat 61 and the rotating shaft, and are opposite to the rolling bearing 62.

[0072] The bearing seat 61 can also extend to the inside of the first accommodating cavity 13 to increase the length of the bearing seat 61 and facilitate the arrangement of other structures. The bearing seat 61 can be connected to the lower shell 10 by the third screw 32, that is, the bearing seat 61 is fixed to the outer side of the first side plate 11 by the third screw 32. The third screw 32 can be a round head square neck screw, which passes through the lower shell 10 and is fixed in the bearing seat 61, and the third screw 32 and the lower shell 10 are sealed with glue to ensure the sealing of the lower shell 10 and avoid leakage.

[0073] The rolling bearing 62 is arranged in the corresponding bearing seat 61 and can roll relative to the corresponding bearing seat 61. The rolling bearing 62 can be a ball bearing or a roller bearing. The rotating shaft 41 is inserted into the rolling bearing 62, and the rotating shaft 41 and the rolling bearing 62 move synchronously, for example, the rolling bearing 62 and the rotating shaft 41 have an interference fit or a transition fit. Among them, the rotating shaft 41 is also inserted into the corresponding bearing seat 61, and the rolling bearing 62, the bearing seat 61 and the rotating shaft 41 remain concentric.

[0074] It can be understood that both ends of the rotating shaft 41 penetrate the lower shell 10 and extend to the outside of the lower shell 10 to cooperate with the bearing seat 61 and the rolling bearing 62. Each end of the rotating shaft 41 is connected to a rolling bearing 62 and a bearing seat 61, so that the rotating shaft 41 is supported by the rolling bearings 62 and the bearing seat 61 at both ends of the rotating shaft 41, and the rolling bearings 62 and the bearing seat 61 can also reduce friction.

[0075] The first retaining ring 63 is arranged on the bearing seat 61, and the second retaining ring 64 is arranged on the rotating shaft 41. The first retaining ring 63 and the second retaining ring 64 are both located on the side of the rolling bearing 62 away from the lower shell 10, and are opposite to the rolling bearing 62 to block the rolling bearing 62. The first retaining ring 63 can be used to limit the rolling bearing 62 from radial movement during the movement, and the second retaining ring 64 can be used to limit the rotating shaft from radial movement during the movement, thereby avoiding the rolling bearing 62, the bearing seat 61 and the rotating shaft from radial movement, ensuring their rotation, and thus ensuring the stirring effect of the stirring member. Among them, the first retaining ring 63 and the second retaining ring 64 can be spring retaining rings.

[0076] In the embodiment of the utility model, the inner wall of the bearing seat 61 may be provided with a first annular groove, and the first retaining ring 63 is disposed in the first annular groove and extends outward from the first annular groove. The outer peripheral surface of the rotating shaft 41 may be provided with a second annular groove, and the second retaining ring 64 is disposed in the second annular groove and extends outward from the second annular groove. The end of the rolling bearing 62 adjacent to the lower shell 10 may be limited by the step surface of the bearing seat 61.

[0077] Continue reading Figures 1 to 4The driving assembly includes a motor 50, which is arranged on the side of the bearing seat 61 away from the lower shell 10, that is, the motor 50 can be arranged on one side, of course, the motor 50 can also be arranged on both sides. The output shaft 51 of the motor 50 is inserted into the rotating shaft 41 and abuts against the rotating shaft 41. By arranging the motor 50 outside the lower shell 10 and using the rolling bearing 62 to increase the force point of the motor 50, the motor 50 is supported, and the circuit connection of the motor 50 is facilitated to realize the control of the motor 50. The motor 50 is used to drive the stirring member 40 to stir the filler and the dirt evenly, which is time-saving and efficient.

[0078] The output shaft 51 of the motor 50 abuts against the rotating shaft 41, and the rotating shaft 41 is driven by the contact between the motor 50 and the rotating shaft 41, without the need to set other structures, thereby simplifying the overall structure. The output shaft 51 of the motor 50 can also be connected to the reduction box 52 of the motor 50 to prevent the output shaft 51 of the motor 50 from rotating too fast, thereby ensuring that the stirring speed of the stirring member is appropriate.

[0079] The end of the rotating shaft 41 facing the motor 50 has a recessed portion, and the recessed portion is the same shape and size as the output shaft 51 of the motor 50. Specifically, the recessed portion has a rotation-stopping surface, and the output shaft 51 of the motor 50 has a fitting surface, and the fitting surface abuts against the rotation-stopping surface. The output shaft 51 of the motor 50 extends into the recessed portion, and the fitting surface of the output shaft 51 of the motor 50 cooperates with the rotation-stopping surface of the recessed portion. By utilizing the fitting and abutting of the fitting surface and the rotation-stopping surface, the output shaft 51 of the motor 50 is transmitted to the rotating shaft 41 when rotating, driving the rotating shaft 41 to rotate synchronously.

[0080] In some possible implementations, the cross-sectional shape of the recessed portion is D-shaped, and the plane section of the recessed portion forms a rotation-stopping surface.
