[0061] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection scope of the present invention.

[0062] Embodiment 1

[0063] In a specific Embodiment 1, as Figure 1 、 Figure 2 and Figure 3 shown, an intelligent toilet includes an upper cylinder 1, a lower cylinder 2, a defecation trough 3, an automatic packing and bag-changing structure 4, a plastic bag assembly 5 and a toilet seat assembly 6; among them,

[0064] A notch is formed in the lower cylinder body 2, and the fecal discharge trough 3 is installed on the notch.

[0065] The automatic packing and bag-changing structure 4 is installed below the upper cylinder body 1, the plastic bag assembly 5 is installed above the upper cylinder body 1, and the toilet cover assembly 6 is installed above the plastic bag assembly 5.

[0066] The automatic packing and bag-changing structure 4 includes a base 4-1, a guide shaft 4-2, a bag pressing rod assembly 4-3, a fixing plate 4-4, a synchronous belt 4-5, a belt pulley 4-6, a connecting shaft 4-7, a gear 4-8, a roller pulling-down device 4-9, a sealing and cutting device 4-10, and a motor driving assembly 4-11.

[0067] The guide shaft 4-2 is installed in parallel on both sides of the base 4-1. The bag pressing rod assembly 4-3 is slidably installed at one end of the guide shaft 4-2. The fixing plate 4-4 is located at the other end of the guide shaft 4-2. The sealing and cutting device 4-10 is installed on the fixing plate 4-4. Both ends of the synchronous belt 4-5 are connected to both ends of the guide shaft 4-2. The belt pulley 4-6 is fixedly connected by the connecting shaft 4-7. The gear is installed at one end of the connecting shaft 4-7. The gear 4-8 is connected to the motor driving assembly 4-11. The roller pulling-down device 4-9 is installed on both sides of the middle of the base 4-1. The motor driving assembly 4-11 is fixed to the right side wall of the base 4-1.

[0068] In this embodiment, the fecal discharge trough 3 is used to store the excrement after automatic packing. The upper cylinder body 1 and the lower cylinder body 2 provide support for the overall structure. The plastic bag assembly 5 is used to store plastic bags. The motor driving assembly 4-11 is used to provide power for the automatic packing and bag-changing structure 4.

[0069] A through hole is provided in the middle of the base 4-1, which serves as the plastic bag feeding port. An annular groove is provided around it for positioning and placing the plastic bag assembly 5. A pair of parallel guide shafts 4-2 are provided on two opposite sides of the base 4-1. A bag pressing rod assembly 4-3 is slidably mounted on the guide rods and nested with the guide shafts 4-2 to achieve positioning and sliding. The bag pressing rod assembly 4-3 cooperates with two synchronous belts 4-5 on both sides. To ensure stability, two belt pulleys 4-6 are connected together by a connecting shaft 4-7 passing through the cavity of the base 4-1, and the other two belt pulleys 4-6 are connected together by another connecting shaft 4-7 passing through the cavity of the base 4-1. A gear is fixed on the connecting shaft 4-7, and the gear is connected to the motor drive assembly 4-11. When the motor drive assembly 4-11 rotates, it will drive the gear 4-8 to rotate. Since the gear 4-8 is fixed to the connecting shaft 4-7, the connecting shaft 4-7 is fixed to the belt pulley 4-6, the belt pulley 4-6 cooperates with the synchronous belt 4-5, and the synchronous belt 4-5 is fixed to both ends of the bag pressing rod assembly 4-3. Therefore, the bag pressing rod assembly 4-3 will move along the guide shaft 4-2. The forward and reverse movement of the bag pressing rod assembly 4-3 can be controlled by the motor drive assembly 4-11. At this time, the incision sealing device 4-10 moves with the movement of the bag pressing rod assembly 4-3. When it moves to the rightmost side, the cutting and sealing of the plastic bag are completed. Then, the roller pulling-down device 4-9 drives the plastic bag to move downward to complete the replacement of the plastic bag, realizing the function of replacing the plastic bag, so that every time the user finishes packing with a plastic bag, a new plastic bag can be automatically replenished. The packed plastic bags are stored in the defecation trough 3.

[0070] In a preferred embodiment, as Figure 4 shown, the bag pressing rod assembly 4-3 includes a bag pressing rod 4-3-1 and a soft rubber pad 4-3-2; the upper and lower ends of the bag pressing rod 4-3-1 have triangular wings. Two circular through holes are provided on both sides of the bag pressing rod 4-3-1 for nested connection with the guide shaft 4-2. Tooth-shaped notches are provided at both ends of the bag pressing rod 4-3-1 for fixing the synchronous belt 4-5; set screw holes are provided on the upper parts of both sides of the bag pressing rod 4-3-1.

[0071] The upper and lower ends of both sides of the bag pressing rod 4-3-1 have triangular wings, which can make the plastic bag converge towards the middle along the inclined plane during the process of squeezing the plastic bag by the bag pressing rod 4-3-1, achieving a more ideal converging effect. The soft rubber pad 4-3-2 is made of high-temperature resistant foamed silica gel material, which can effectively protect the bag pressing rod 4-3-1 from being damaged during use, provide buffering and a better bag pressing effect. The set screw holes can tightly fit the bag pressing rod 4-3-1 and the synchronous belt 4-5 to prevent slipping.

[0072] In a preferred embodiment, a snap ring 4-12 is provided on the outer side of the belt pulley 4-6. Both sides of the connecting shaft 4-7 are cut into a D shape, and a D-shaped groove hole is provided in the center of the belt pulley 4-6.

[0073] The outer side of the pulley 4-6 is limited by a snap ring 4-12. The D-shaped connecting shaft 4-7 is matched with the D-shaped slot hole of the pulley 4-6, and the two do not rotate relative to each other, resulting in better stability.

[0074] In a preferred embodiment, as Figure 5 shown, the motor drive assembly 4-11 includes a housing 4-11-1, a motor 4-11-2, an upper cover 4-11-3, and a multi-stage gear set 4-11-4. Corresponding grooves are provided on the inner walls of the housing 4-11-1 and the upper cover 4-11-3. The gear set 4-11-4 is installed on the grooves. The upper cover 4-11-3 and the housing 4-11-1 are fixed by screws, and the motor 4-11-2 is fixed on the housing 4-11-1.

[0075] In this embodiment, the motor 4-11-2 is a DC motor, which is small in size, low in price, and convenient to install. The motor 4-11-2 is fixedly installed on the housing 4-11-1. The housing 4-11-1 is provided with grooves for installing the gear rotating shaft. A gear set 4-11-4 is sleeved on the rotating shaft, and the gears mesh with each other to realize the change of output speed and torque to meet the use requirements. The last stage of the gear set 4-11-4 meshes with the gear 4-8 to realize power transmission. The upper cover 4-11-3 and the housing 4-11-1 are fixed by screws. When the upper and lower covers are fixed, each rotating shaft is nested in the corresponding groove. The motor drive assembly 4-11 is fixed on the side wall of the right part of the base 4-1.

[0076] In a preferred embodiment, as Figure 6 shown, the sealing and cutting device 4-10 includes a fixed seat 4-10-1, a heating element 4-10-2, and a T-shaped cutting blade 4-10-3. The heating element 4-10-2 is fixed on the fixed seat 4-10-1. The T-shaped cutting blade 4-10-3 covers the heating element 4-10-2, and a high-temperature insulating film is provided between the T-shaped cutting blade 4-10-3 and the heating element 4-10-2.

[0077] The fixed seat 4-10-1 is installed on the fixed plate 4-4. The material of the fixed seat 4-10-1 has high-temperature resistance. Both ends of the heating element 4-10-2 are connected to the circuit through wires. The T-shaped cutting blade 4-10-3 is made of a heat-conducting material, which can transfer the heat generated by the heating element 4-10-2 to thermally cut the plastic bag. To isolate the situation of mutual conduction between components, a high-temperature insulating film is provided between the T-shaped cutting blade 4-10-3 and the heating element 4-10-2.

[0078] Embodiment 2

[0079] In a preferred Embodiment 2, as Figure 3 and Figure 7As shown, the automatic packing and bag changing structure 4 also includes a buffer rod 4-13 and three sensors 4-14; the buffer rod 4-13 is provided with double-wing structures at both ends of the upper and lower sides, and the buffer rod 4-13 is slidably installed on the guide shaft 4-2; two of the sensors 4-14 are located at the initial position of the guide shaft 4-2, and the other is located at the joint between the bag pressing rod assembly 4-3 and the sealing and cutting device 4-10.

[0080] Since the garbage bag contains excrement, it has a certain weight. During hot-melt packaging, since the sealing mouth is in a molten state, it may be pulled and deformed by gravity, resulting in an unsatisfactory effect of the hot-sealing. For this reason, the buffer rod 4-13 is designed in this embodiment. The buffer rod 4-13 has double-wing structures at both ends of the upper and lower sides, which complement the bag pressing rod 4-3-1 and play a role in two-way folding of the plastic bag to achieve a better folding effect. The buffer rod 4-13 is slidably installed on the guide shaft 4-2, and springs are sleeved on the back of both sides along the guide shaft 4-2, and the bottom of the spring is supported by the fixed plate 4-4. The front of the buffer rod 4-13 is limited by the retaining ring 4-12.

[0081] When packing plastic bags, the bag pressing rod 4-3-1 first contacts the buffer rod 4-13, squeezes the buffer rod 4-13 and moves it backwards for a certain distance, and then fits with the T-shaped cutting piece 4-10-3 of the sealing and cutting device 4-10. After fitting, the motor 4-11-2 stops rotating and locks. At this time, due to the action of the spring force, the bag pressing rod 4-3-1 and the buffer rod 4-13 always clamp the plastic bag. In this way, the pulling effect of the gravity of the excrement in the plastic bag on the plastic bag during the hot melt process is eliminated, and a better hot melt plastic sealing effect is achieved.

[0082] In order to realize the automatic packaging function and ensure the accuracy of each packaging position and the packaging quality, a sensor 4-14 is installed at the specified position of the base 4-1. The sensor 4-14 is selected from one of a micro switch sensor, a photoelectric sensor or an infrared sensor. The sensor 4-14 is set at the initial position of the bag pressing rod 4-3-1 to ensure that the bag pressing rod 4-3-1 returns to the specified position after each packaging. The sensor 4-14 is installed at the place where the bag pressing rod 4-3-1 and the sealing and cutting device 4-10 are in contact, so that when the bag pressing rod 4-3-1 reaches the specified heat sealing position, it can control the motor 4-11-2 to stop rotating, preventing the motor 4-11-2 from being blocked and damaged.

[0083] In a preferred embodiment, Figure 8 and Figure 9As shown, the roller down-dropping device 4-9 includes a driving part 4-9-1, a driven part 4-9-2 and a transmission shaft 4-9-3; the driving part 4-9-1 includes a driving motor 4-9-1-1, a driving part housing 4-9-1-2, a driving part upper cover 4-9-1-3, a driving multi-stage transmission gear 4-9-1-4, a driving rubber roller 4-9-1-5 and a torsion spring 4-9-1-6; the driven part 4-9-2 includes a driven part housing 4-9-2-1, a driven part upper cover 4-9-2-2, a driven multi-stage transmission gear and a driven part rubber roller 4-9-2-3; corresponding driving part grooves are provided on the inner walls of the driving part housing 4-9-1-2 and the driving part upper cover 4-9-1-3, corresponding driven part grooves are provided on the driven part housing 4-9-2-1 and the driven part upper cover 4-9-2-2, the driving multi-stage transmission gear 4-9-1-4 is installed in the driving part groove, the driven multi-stage transmission gear is installed in the driven part groove, the driving motor 4-9-1-1 is installed on one side of the driving part housing 4-9-1-2, the driving rubber roller 4-9-1-5 and the torsion spring 4-9-1-6 are located on the other side of the driving part housing 4-9-1-2, the driving rubber roller 4-9-1-5 is installed on the outside of the driving part housing 4-9-1-2, and the torsion spring 4-9-1-6 is installed inside the driving part housing 4-9-1-2 and connected to the driving multi-stage transmission gear 4-9-1-4; the driven part rubber roller 4-9-2-3 is installed on one side of the driven part housing 4-9-2-1 and corresponds to the position of the driving rubber roller 4-9-1-5.

[0084] When the drive motor 4-9-1-1 drives the active multi-stage transmission gear 4-9-1-4 to rotate, it drives the transmission shaft 4-9-3 to operate, and at the same time drives the driven multi-stage transmission gear to rotate, and then drives the active rubber roller 4-9-1-5 to rotate relatively. Since the plastic bag is sandwiched between the rubber rollers, the garbage bag is driven to be replaced downward. In this embodiment, in this structure, the active part groove and the driven part groove are arranged at appropriate positions according to the actual meshing situation of the active multi-stage transmission gear 4-9-1-4 and the driven multi-stage transmission gear, for positioning and installing the pin shaft. When the driven part housing 4-9-2-1, the driven part upper cover 4-9-2-2, the active part housing 4-9-1-2 and the active part upper cover 4-9-1-3 are closed, the pin shaft is restricted to the designated groove position in the device. In this way, the active multi-stage transmission gear 4-9-1-4 and the driven multi-stage transmission gear are positioned at the designated positions, and the whole device is in a sealed state. All gear transmissions are carried out in the sealed cavity, which can effectively reduce the gear transmission noise heard outside. The torsion spring 4-9-1-6 is used to optimize the clamping method of the roller on the plastic bag. Although the active rubber roller 4-9-1-5 itself has elasticity and is easy to deform, by applying a downward extrusion force to the plastic bag, the two active rubber rollers 4-9-1-5 will undergo elastic deformation, and the garbage bag can be squeezed into the space between the two rollers. Then, relying on the restoring force of the elastic deformation of the two active rubber rollers 4-9-1-5, the plastic bag is clamped between the two rollers. However, the elastic deformation of rubber itself is limited. By forcibly squeezing to cause deformation, the clamping force becomes poor, the plastic bag cannot be clamped, and it may also cause damage to the plastic bag and the structure of the pulling device due to excessive force, affecting the user experience. The torsion spring 4-9-1-6 includes a rotating arm and a fixed arm. When in the initial state, the two active rubber rollers 4-9-1-5 are in contact with each other. At this time, the torsion spring 4-9-1-6 is also in the initial state and has basically no force on the pin shaft. When the plastic bag is inserted from point A, the right roller will rotate clockwise around the fixed shaft of the torsion spring 4-9-1-6, as shown in the direction B in Figure 8 shown, making it easier for the plastic bag to be inserted between the rollers. When the force is removed, due to the restoring force of the torsion spring 4-9-1-6, the two active rubber rollers 4-9-1-5 will move closer to the contact direction again. Since the plastic bag itself has a thickness, the two active rubber rollers 4-9-1-5 must be in a clamped state with respect to the plastic bag. In this way, relying on the rotation of the rotating arm of the torsion spring 4-9-1-6, the insertion of the plastic bag is more convenient and the clamping is more reliable. At the same time, it is not easy to damage the structure of the device.

[0085] In a preferred embodiment, as Figure 10As shown, the plastic bag assembly 5 includes a storage main body 5-1, a cover body 5-2, and a plastic bag 5-3. The storage main body 5-1 is provided with a first through hole, and outside the first through hole is a plastic bag groove for storing the plastic bag 5-3. The cover body 5-2 is provided with a second through hole corresponding to the first through hole. A gap is provided between the cover body 5-2 and the inner side wall of the plastic bag groove to form an outlet for the plastic bag 5-3. The inner side wall of the plastic bag groove is designed with a flanging structure, and the outer edge of the cover body 5-2 is provided with a hemming structure, which is snap-connected to the outer wall of the storage main body 5-1.

[0086] Since the plastic bag 5-3 is a consumable, there needs to be a space in the toilet for storing the plastic bag 5-3. The plastic bag 5-3 is in the shape of a cylindrical strip, and the length of the plastic bag 5-3 is about 10m (which can be lengthened or shortened according to requirements), so as to facilitate multiple hot-melt cutting and packing. After being repeatedly folded, it is placed in the plastic bag groove, and then the cover body 5-2 is covered on the opening of the plastic bag 5-3 groove to prevent the plastic bag 5-3 from swelling and overflowing. The inner side wall of the plastic bag groove is designed with a flanging structure, which can make the edge of the bag outlet smooth and not easily scratch the plastic bag 5-3.

[0087] In a preferred embodiment, as Figure 11 shown, the toilet seat assembly 6 includes a toilet seat ring 6-1, a toilet seat cushion 6-2, and a toilet cover 6-3. The toilet seat ring 6-1 is in a circular ring structure, with a through hole in the middle, and an annular toilet seat cushion groove is provided outside the through hole.
