DETAILED DESCRIPTION

[0014] In the following description, numerous details are provided to facilitate a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description relates only to preferred embodiments of the present invention, and that the present invention may be practiced without one or more of these details. Furthermore, certain technical features well known in the art have not been described to avoid confusion with the present invention.

[0015] In order to more clearly illustrate the technical solutions of the present invention, specific embodiments are provided below for illustration.

[0016] Example See also Figure 1-15This embodiment provides a bagged excrement collection device, which includes: a toilet seat 1, a toilet box bracket 6, a support plate frame 7, an excrement collection bag 11 and a tightening assembly; the toilet seat 1 is installed above the toilet box bracket 6; the toilet box bracket 6 is installed above the support plate frame 7; a feces collection box 4 is detachably provided in the toilet box bracket 6; there are multiple excrement collection bags 11, and the multiple excrement collection bags 11 are stacked in sequence; the bag body of the excrement collection bag 11 is sleeved in the excrement collection box 4; a drawstring 21 is provided at the bag opening of the excrement collection bag 11. The opening of the excrement collection bag 11 is connected to multiple fixed ends 23 via tear lines 24; multiple fixing pins 16 corresponding to the fixed ends 23 are provided around the top of the toilet box bracket 6, and the fixed ends 23 are connected to the fixing pins 16; the tightening assembly is used to tighten the drawstring 21 of the excrement collection bag 11 located at the top; the tightening assembly is installed on the toilet box bracket 6, and an opening 5 is provided on the side of the excrement collection box 4 close to the tightening assembly, and the drawstrings 21 of multiple excrement collection bags 11 are connected to the tightening assembly via the opening 5.

[0017] In this embodiment, multiple feces collection bags 11 can be placed in the feces collection box 4 in sequence, and their edges can be fixed to the fixing pin 16 through the fixing end 23. In some implementations, the fixing end 23 has a pin hole that matches the fixing pin 16, and the fixing end 23 is placed on the fixing pin 16 through the pin hole. In other implementations, such as Figure 3 As shown, the device also includes a fixing sleeve 26 and a fixing ring 25 that fits with the fixing sleeve 26. The fixed ends 23 of the multiple excrement collection bags 11 are sequentially mounted on the fixing sleeve 26, and the fixing ring 25 is mounted on the fixing sleeve 26 to secure the fixed ends 23 of the multiple excrement collection bags 11. The fixing sleeve 26 is provided with a pin hole that fits with the fixing pin 16. In this embodiment, the fixed ends 23 of the multiple excrement collection bags 11 are first placed on the fixing sleeve 26. The fixing ring 25 is then installed to clamp the multiple fixed ends 23. Finally, the fixing sleeve 26 is mounted on the fixing pin 16. This completes the installation of the excrement collection bags 11. The entire installation process is simple, the fixing method is reliable, and it is user-friendly. The fixing sleeve 26 can be aligned with the axis of the fixing pin 16. This not only ensures that the toilet seat 1 and its connected components (such as the air collection ring 2 described below) are level, but also prevents these components from squeezing the periphery of the excrement collection bags 11, thereby affecting the automatic sealing of the excrement collection bags 11.

[0018] The number of feces collection bags 11 placed each time can be selected according to actual needs. For example, 20 or more feces collection bags can be placed to meet the needs of long-term use.

[0019] In this embodiment, after the user has finished defecating, the tightening assembly can be used to tighten the drawstring 21 of the topmost excrement collection bag 11. Due to the provision of the easy-tear line 24, the topmost excrement collection bag 11 is disconnected from the corresponding fixed end 23, and the excrement collection bag 11 is automatically sealed as the drawstring 21 is tightened.

[0020] The above solution, by stacking multiple excrement collection bags 11 in sequence, can be used multiple times by the user without having to put on the bag each time, which helps to improve the user experience; by providing a fixed end 23 on the excrement collection bag 11 and connecting it with a tear line 24, it can be convenient to fix the excrement collection bag 11 and prevent the fixed position from affecting the automatic tightening of the excrement collection bag 11; by providing a tightening component connected to the drawstring 21, the excrement collection bag 11 can be automatically sealed after the user defecates, which is convenient to handle; by providing a detachable excrement collection box 4, it can be easily cleaned, which helps to meet the emergency use needs in the scenario where the excrement collection bag 11 is not installed in time. In short, the bagged excrement collection device of this solution is easy to use, has a stable and reliable working process, can achieve automatic sealing, and can meet the needs of people with motor function impairments for operational convenience and stability.

[0021] See also Figure 5-11 The tightening assembly includes a fixing plate 27, the upper part of which is concave downward to form a U-shaped groove 18; a pushing chamber 35, a chute 41, a pressing chamber 44, a pushing assembly and a rotating assembly are provided on the side of the fixing plate 27 away from the toilet box bracket 6; the pushing chamber 35 is vertically arranged, the chute 41 is horizontally arranged, and the bottom of the chute 41 is flush with the top of the pushing chamber 35; the pressing chamber 44 is arranged below the chute 41, and a pressing port 46 is provided at the bottom of the chute 41, and the chute 41 is connected to the pressing port 46 via the pressing port 46. 6 is connected to the compacting chamber 44; a pressing piece 22 is provided on the drawstring 21 of the excrement collecting bag 11, and the pressing pieces 22 of multiple excrement collecting bags 11 are stacked in sequence in the pushing chamber 35, and the bottom of the target pressing piece is flush with the bottom of the chute 41. The pushing component is used to push the target pressing piece to slide along the chute 41 to the compacting port 46, and the target pressing piece enters the compacting chamber 44 through the compacting port 46 and draws the rope 21 under the drive of the rotating component; wherein, the target pressing piece is the pressing piece of the excrement collecting bag 11 located at the top.

[0022] like Figure 4 As shown, the tightening assembly may further include a housing 17 , which may be disposed outside the fixing plate 27 .

[0023] like Figure 9 As shown, a receiving groove 40 is installed on one side of the fixing plate 27 near the feces collecting box 4, and slots of the same size as the U-shaped groove 18 are provided on both sides of the receiving groove 40. The receiving groove 40 can be used to temporarily place the draw cord 21 extending outward.

[0024] like Figure 10-11 A drawstring escape groove 42 is provided below the U-shaped groove 18. The drawstring escape groove 42 is provided to accommodate the drawstring 21. The drawstring escape groove 42 may be quadrilateral in shape, while the pressing plate 22 may be circular in shape. The width of the drawstring escape groove 42 is smaller than the thickness of the pressing plate 22, which helps prevent the drawstring 21 from falling out of the push cavity 35.

[0025] In this embodiment, an opening 5 is provided at the top of the chute 41 toward the side of the feces collection box 4. This opening 5 facilitates the movement of the pull cord 21 during the movement of the pressing piece 22, ensuring the stability of the pushing process. The top wall of the chute 41 is L-shaped, which can prevent the pressing piece 22 from falling.

[0026] In some embodiments, the height of the chute 41 can be the same as the thickness of the pressing tablet 22. This ensures that only the topmost pressing tablet 22 is transported, ensuring the reliability of the tightening process. During use, the pressing tablets 22 of each feces collection bag 11 can be stacked and placed into the push chamber 35 in the order in which the feces collection bags 11 are assembled. After the user completes defecation, the topmost pressing tablet 22 (i.e., the target pressing tablet) slides along the chute 41 under the push of the push assembly and falls into the compacting chamber 44 through the compacting opening 46. The rotary assembly can then be used to drive the drawstring 21 to tighten the feces collection bag 11, thereby completing the automatic sealing of the feces collection bag 11.

[0027] The above solution cooperates with the pushing cavity 35, the chute 41 and the pressing cavity 44 to accurately tighten the drawstring 21 of the uppermost feces collection bag 11 after defecation, thereby helping to ensure the user experience.

[0028] See Figure 11 The top of the chute 41 is provided with a placement opening 45, on which a pressure block 19 is mounted. The placement opening 45 is located directly above the compacting cavity 44. The bottom of the pressure block 19 can be designed as a convex surface, and the pressure block 19 and the placement opening 45 can be assembled and matched by mechanical extrusion. The placement opening 45 facilitates the placement of the pressure piece 22. The placement of the pressure block 19 ensures that the topmost pressure piece 22 is within the chute, preventing the topmost pressure piece 22 from protruding through the placement opening 45, thereby ensuring the stability of the tightening operation.

[0029] See also Figure 6 、 7 , 11, the pushing assembly includes a pushing motor 28 and a push plate 31, and the pushing motor 28 drives the push plate 31 to slide in the slide groove 41. In this embodiment, the pushing motor 28 can be used to drive the push plate 31 to push the target tablet. In some implementation schemes, the rotational motion output by the pushing motor 28 can be converted into a linear motion by using the connection method of the screw rod and the screw nut. Specifically, the output shaft of the pushing motor 28 is connected to the screw rod, and the push plate 31 is connected to the screw nut. The rotation of the output shaft of the pushing motor 28 can drive the push plate 31 to slide in the slide groove 41.

[0030] like Figure 8As shown, a push block 39 is disposed within the push chamber 35. The top of the push block 39 contacts the bottommost pressing piece 22. The push block 39 is connected to the lifting motor 29. In the solution of this embodiment, the lifting motor 29 can be used to drive the push block 39 to push the pressing piece 22 upward, thereby ensuring that the bottom of the topmost pressing piece 22 is always flush with the bottom of the chute 41, thereby ensuring the continuity and stability of the tightening of the feces collection bag 11.

[0031] Continue reading Figure 8 A transition block 32 is provided between the lifting motor 29 and the push block 39. The push block 39 is connected to the lifting motor 29 via the transition block 32. A buffer spring 38 is provided between the push block 39 and the transition block 32. By providing the buffer spring 38, the elasticity of the buffer spring 38 can be utilized to ensure that the top of the uppermost pressing piece 22 and the bottom of the pressing block 19 are in close contact, thereby helping to ensure the reliability of the subsequent pushing action.

[0032] The rising motor 29 can be connected to the transition block 32 by a screw rod and a screw nut. Specifically, the output end of the rising motor 29 can be connected to the screw rod, and the screw nut on the screw rod can be connected to the transition block 32.

[0033] See Figure 6 The device also includes a clamping bearing 33, a pressure plate 20 and a clamping push rod 36; the clamping push rod 36 is connected to the pressure plate 20; the pressure plate 20 is located above the slide groove 41, and the clamping bearing 33 is installed below the pressure plate 20. A through hole is provided at the top of the slide groove 41, and the through hole is located directly above the clamping port 46. The clamping bearing 33 moves downward under the drive of the clamping push rod 36 and enters the slide groove 41 through the through hole. When the clamping bearing 33 moves to the lowest position, the bottom of the clamping bearing 33 is not higher than the clamping port 46; the rotating assembly includes a rotating motor 34 and a rotating wheel 43, and the rotating motor 34 is connected to the rotating wheel 43; the rotating wheel 43 passes through the bottom of the clamping cavity 44 and enters the clamping cavity 44; the target pressed piece enters the clamping cavity 44 under the push of the clamping bearing 33 and its bottom abuts against the top of the rotating wheel 43.

[0034] In the solution of this embodiment, when the target tablet reaches the pressing port 46, the pressing push rod 36 can be used to drive the pressing bearing 33 downward. The pressing bearing 33 enters the chute 41 through the through hole at the top of the chute 41, contacts the top of the target tablet (at this time, the inner ring of the pressing bearing 33 contacts the target tablet) and continues to press down, so that the bottom of the target tablet abuts against the top of the rotating wheel 43, and presses the target tablet into the pressing cavity 44. Afterwards, the rotating wheel 43 rotates driven by the rotating motor 34. Since the target tablet is clamped between the pressing bearing 33 and the rotating wheel 43, the target tablet rotates as the rotating wheel 43 rotates. The pull rope 21 is gradually wrapped around the rotating wheel 43, thereby realizing the automatic sealing of the feces collection bag 11.

[0035] The above solution can utilize the rotating wheel 43 to rotate and drive the pressing piece 22 to rotate, thereby automatically sealing the feces collection bag 11. The overall structure of this solution is simple and reliable.

[0036] like Figure 7 As shown, the rotating wheel 43 is a conical wheel; a preload spring 37 is connected below the conical wheel. Specifically, the rotating motor 34 can be fixed to a plate, with the preload spring 37 mounted below the plate. In this case, the preload spring 37 is indirectly connected to the conical wheel through the plate and the rotating motor 34. This preload spring 37 ensures that the top of the conical wheel always abuts the bottom of the target tablet, thereby ensuring the reliability of the tensioning process of the pull cord 21.

[0037] The surface of the conical wheel is smooth and preferably made of stainless steel, which can reduce the friction between the pull rope 21 and the conical surface as much as possible, ensuring that the conical wheel is separated from the pull rope 21 after descending.

[0038] See also Figure 7 、 11 In this embodiment, a lowering motor 30 is provided on the side of the fixing plate 27 away from the toilet box bracket 6, and the lowering motor 30 is connected to the conical wheel to drive the conical wheel to move up and down. Figure 7 In the example, the assembly consisting of the rotating motor 34 and the preload spring 37 can be integrally fixed to a plate, with the lowering motor 30 indirectly connected to the tapered wheel via this plate. The lowering motor 30 can drive the entire assembly consisting of the rotating motor 34, rotating wheel 43, and preload spring 37 up and down via a lead screw and lead screw nut. The specific connection method is similar to that between the raising motor 29 and the transition block 32 and will not be further described.

[0039] In this embodiment, after the feces collection bag 11 is sealed, the descending motor 30 can be used to drive the conical wheel downward. Due to the conical wheel's structural characteristics of being smaller at the top and larger at the bottom, the pull cord 21 wrapped around it can be quickly separated from the conical wheel during the downward movement, leaving the pull cord 21 and the target compressed tablet within the compacting chamber 44. This facilitates the subsequent removal of the sealed feces collection bag 11.

[0040] In this embodiment, when the pressing bearing 33 moves to the lowest position, the bottom of the pressing bearing 33 is flush with the bottom of the pressing opening 46. This prevents the drawstring 21 from being entangled in the pressing bearing 33, thereby ensuring that the sealed feces collection bag 11 can be easily removed later.

[0041] See also Figure 13 、 14A compression flap 3 is provided above the toilet bowl holder 6. The bottom of one side of the compression flap 3 extends downward to form a fixed protrusion 47. A tensioning pin 48 is vertically provided on one side of the top frame of the toilet bowl holder 6. The portion of the tensioning pin 48 located below the top frame is sheathed with a tensioning spring 49. The portion of the tensioning pin 48 located above the top frame is hingedly connected to the fixed protrusion 47. The toilet seat 1 is provided above the compression flap 3. The bottom of the tensioning pin 48 forms a stopper, and the bottom of the tensioning spring 49 abuts against the stopper, while the top abuts against the bottom of the top frame.

[0042] In this embodiment, the pressing flap 3 can rotate relative to the tension pin 48. The pressing flap 3 and the fixed protrusion 47 form an L shape as a whole. Figure 13 As shown, when the compression flap 3 is in a horizontal position, the tension pin 48 is pulled upward by the fixed protrusion 47, and the tension spring 49 is compressed. Under the tension of the tension spring 49 and the gravity of the compression flap 3, toilet seat 1, etc., the compression flap 3 and the components thereon are kept in a horizontal position. Figure 14 As shown, when the excrement collection bag 11 needs to be placed, the compression flap 3 can be manually flipped. As the compression flap 3 gradually reaches the vertical position, the tension spring 49 releases its thrust, pulling the tension pin 48 downward. When the compression flap 3 is in the vertical position, the fixing protrusion 47 is in the horizontal position. At this time, the compression flap 3 can be maintained in the open state without the need for external force, which helps facilitate the installation of the excrement collection bag 11.

[0043] See also Figure 1 、 12 The device also includes an air collecting ring 2, which is located between the compression flap 3 and the toilet seat 1. A plurality of air collecting holes 91 are provided on the inner side of the air collecting ring 2, and the air collecting holes 91 are connected to an air suction purification component to discharge the gas in the feces collection box 4 after purification. Specifically, the air suction purification component may include a purification fan, which is connected to the plurality of air collecting holes 91 through a pipe. The gas in the feces collection box 4 is purified by the purification fan and then discharged. The air collecting ring 2 may be made of a rubber material with a certain hardness. By providing the air collecting ring 2, this solution can purify the exhaust gas during the user's use, thereby avoiding the exhaust gas from polluting the environment around the device and improving the user's comfort when using the toilet.

[0044] Continue reading Figure 12 A splash-proof curtain 10 is installed between the air collecting ring 2 and the toilet seat 1. The inner side of the splash-proof curtain 10 extends downward to form a curtain body, with the bottom of the curtain body lower than the air collecting ring 2. A gap is formed between the curtain body and the air collecting hole 91. The splash-proof curtain 10 can be made of plastic and can be fixed to the air collecting ring 2 by gluing. The toilet seat 1 can also be fixed to the splash-proof curtain 10 by gluing. Both are consumable parts, and the gluing method allows for easy replacement.

[0045] The entire splash curtain 10 can be made of materials such as plastic and rubber, which will not be described in detail. The above solution, by providing the splash curtain 10, effectively prevents feces and urine from contaminating the air collection ring 2, while also preventing feces and urine from being drawn into the air collection ring 2 during the air collection purification operation. Furthermore, a certain distance is maintained between the curtain and the air collection hole 91. This design ensures that the curtain does not block the smooth entry of exhaust gas into the air collection hole 91, thereby ensuring the normal operation of the air collection purification component.

[0046] See also Figure 1 、 15 A plurality of guide shafts 8 are vertically provided on the support frame 7, and guide springs 9 are sleeved on the guide shafts 8. The toilet box holder 6 is mounted on the support frame 7 via the guide shafts 8. A support plate 12 is mounted on the support frame 7, and the support plate 12 is located below the toilet box holder 6 and is mounted on the guide shafts 8; the guide springs 9 are located between the support plate 12 and the guide shafts 8.

[0047] The guide spring 9 addresses the uneven pressure caused by varying buttock shapes. When the toilet seat 1 contacts the buttocks, the guide spring 9 cushions the pressure, preventing damage to the mechanism caused by the fixed height of the toilet bowl holder 6. It also ensures a close fit between the buttocks and the toilet seat 1. This not only effectively lifts the toilet bowl holder 6, preventing contamination of the surrounding area with feces and urine, but also facilitates the collection of feces and urine, and improves the air environment by creating a relatively sealed space.

[0048] Continue reading Figure 15 , a driving assembly is provided under the support plate 12, and the driving assembly is connected to the support plate 12 to drive the support plate 12 to move up and down along the guide shaft 8. In this embodiment, the driving assembly includes a first driving motor 13, a driving plate 15 and a lifting arm 14. The first driving motor 13 is connected to the driving plate 15 to drive the driving plate 15 to move in the horizontal direction; one end of the lifting arm 14 is hinged to the driving plate 15, and the other end is hinged to the bottom of the support plate 12. The first driving motor 13 and the driving plate 15 can be connected by a screw and a screw nut. Specifically, the first driving motor 13 is connected to the screw, and the driving plate 15 is arranged on the screw as a screw nut. When the driving plate 15 is movable, the lifting arm 14 can rotate relative to the driving plate 15, thereby pushing the toilet box bracket 6 up and down. This structural design can facilitate the integration of the device into nursing beds, wheelchairs and other devices of different heights.

[0049] The device of this embodiment is suitable for defecation management in situations such as wheelchairs and nursing beds. The device has a simple overall structure, making it easy to integrate into wheelchairs, nursing beds, and the like. Furthermore, the device fully considers user autonomy, allowing for the installation of multiple feces collection bags 11 prior to use. The entire installation process is quick and easy to operate.
