Description

Technical Field

[0001] This utility model relates to the field of nursing bed technology, specifically to a negative pressure toilet structure for an intelligent commode nursing bed. Background Technology

[0002] With the increasing aging of my country's population, the health and quality of life of the elderly have become the focus of social attention. Currently, there are 35 million elderly and disabled people in my country who are completely disabled and whose main mode of living is bedridden and require full-time care. In response to this emerging market demand, many companies at home and abroad have launched intelligent nursing bed products with their own unique features.

[0003] Although these nursing beds are all touted as intelligent, they are essentially just using traditional electromechanical control methods, such as PLC control, to manipulate the bed to produce certain degree of shape changes in order to assist patients. However, in actual use, their toilet structure is mostly in a fixed position. Bedridden patients, due to their limited physical activity, cannot adjust their body posture as freely as healthy people. As a result, it is difficult to align the toilet for urination and defecation, and it is also difficult to ensure that the flushing is effective. Without the assistance of nursing staff, the mattress often gets dirty and wet, causing great inconvenience and trouble for patients and nursing staff. It may also increase the possibility of other health risks caused by hygiene problems for patients, and increase the workload and difficulty of subsequent cleaning for nursing staff. Therefore, we propose a negative pressure toilet structure for intelligent commode nursing beds. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a negative pressure toilet structure for an intelligent commode care bed, comprising:

[0005] A guide frame is installed at the lower end of the bed frame, and a bracket is provided on the upper end surface of the guide frame;

[0006] The negative pressure toilet body is installed on the upper end of the bracket;

[0007] An X-axis moving component is mounted on the guide frame, and the X-axis moving component is used to realize the movement of the bracket along the X-axis;

[0008] A lifting platform is located above the negative pressure toilet body, and a toilet seat is detachably mounted on the upper surface of the lifting platform.

[0009] A lifting assembly is mounted on the bed frame, and the lifting assembly is used to move the lifting platform closer to or further away from the negative pressure toilet body.

[0010] In some embodiments, the X-axis moving component includes a first stepper motor mounted on a guide frame, the output end of which is connected to a first lead screw via a reducer, and the exterior of the first lead screw is connected to a bracket via a nut seat.

[0011] In some embodiments, guide strips are connected to both side walls of the bracket, and guide grooves are provided along the length direction on the inner side wall of the guide bracket, with the guide strips slidably engaged with the guide grooves.

[0012] In some embodiments, the lifting assembly includes a second stepper motor, the output end of which is connected to a second lead screw via a reducer, and a connecting frame is mounted on the outside of the second lead screw via a nut seat, the connecting frame being connected to the lifting platform.

[0013] In some embodiments, the toilet seat includes two seat plates and two backrests, with the two seat plates fixed parallel to each other between the two backrests.

[0014] In some embodiments, the mounting plate is provided with a square groove, through which the toilet seat fits into the lifting platform.

[0015] In some embodiments, a block is fixed to the lower end face of the platform, and a groove is provided on the upper end face of the lifting platform, with the block inserted into the groove.

[0016] This utility model has at least the following beneficial effects:

[0017] 1. By setting up an X-axis moving component to adjust the position of the negative pressure toilet body and a lifting component to adjust the height of the toilet seat, the position of the negative pressure toilet body and toilet seat can be adjusted according to the specific circumstances of patients with different physical conditions, body types, and bedridden postures during urination and defecation. This ensures that the position of urination and defecation remains accurate, effectively avoiding many inconveniences and hygiene problems caused by a fixed toilet position. It provides a more comfortable, convenient, and hygienic excretion experience for bedridden patients, reduces the workload of nursing staff in subsequent cleaning, and significantly improves the quality and efficiency of overall nursing care.

[0018] 2. When the bracket is in motion, its guide bar moves smoothly in a straight line along the predetermined trajectory of the guide groove, which can effectively limit various unnecessary shaking, deviation or torsion and other unstable phenomena that may occur during the movement of the bracket, and ensure that the bracket maintains straightness and stability throughout the entire movement.

[0019] 3. For detachable toilet seats, when installing the toilet seat, the insert can be embedded into the corresponding groove, which strictly limits the horizontal movement of the toilet seat. The toilet seat can always maintain its stable position on the lifting platform and will not easily shift, slide or shake horizontally. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figures 1-5As shown, this utility model provides a technical solution: a negative pressure toilet structure for an intelligent commode care bed, including a guide frame 1, a negative pressure toilet body 2, an X-axis moving component 4, a lifting component 5, and a lifting platform 6. The guide frame 1 is installed at the lower end of the bed frame, and a bracket 3 is provided on the upper end surface of the guide frame 1. The negative pressure toilet body 2 is installed on the upper end surface of the bracket 3. The negative pressure toilet body 2 is an intelligent toilet with a warm water washing head, which is existing technology. The specific internal structure will not be described in detail here. The X-axis moving component 4 is installed on the guide frame 1, and the X-axis moving component 4 is used to realize the bracket 3 moving along the X-axis... The lifting platform 6 is located above the negative pressure toilet body 2, and a toilet seat 7 is detachably mounted on the upper surface of the lifting platform 6. The toilet seat 7 can be installed by screw fastening. The lifting component 5 is located on the bed frame and is used to move the lifting platform 6 closer to or further away from the negative pressure toilet body 2. The nursing bed is equipped with a control system, which uses a control program to control the X-axis moving component 4 to drive the negative pressure toilet body 2 to move in the X-axis direction, moving it below the toilet seat 7, so that the patient can urinate and defecate. In addition, the lifting component 5 can adjust the toilet seat 7 to a suitable height to facilitate the patient's urination and defecation.

[0029] The aforementioned negative pressure toilet body 2 is a smart toilet with a warm water washing head. This is existing technology, and its specific internal structure will not be described in detail here. Its working principle can be explained as follows:

[0030] Negative pressure formation: This is generally achieved by installing an exhaust duct, a fan, and a ventilation duct between the toilet seat and the water tank. When the fan is running, the exhaust duct draws air from the annular area above the flush nozzle of the toilet seat, creating a negative pressure state inside the toilet and thus preventing odors from escaping.

[0031] Warm water supply: Instantaneous warm water cleaning heads typically use high-power heating elements, such as ceramic heaters, which can heat cold water to the set temperature in a short time, providing users with a stable supply of warm water. When the cleaning function is activated, the cold water is rapidly heated by the heating element and sprayed out through the nozzle.

[0032] Among them, see Figure 2 and Figure 3 As shown, the X-axis moving component 4 includes a first stepper motor 41 mounted on the guide frame 1. The output end of the first stepper motor 41 is connected to a first lead screw 42 through a reducer. The outside of the first lead screw 42 is connected to the bracket 3 through a nut seat. When the first stepper motor 41 is started, the first lead screw 42 can be rotated by the first stepper motor 41, thereby realizing the movement of the bracket 3 along the length direction of the guide frame 1, and thus adjusting the negative pressure toilet body 2 to move below the toilet seat 7.

[0033] Further, see Figure 4As shown, guide bars 9 are connected to both sides of the bracket 3. The inner side wall of the guide 1 is provided with a guide groove 10 along the length direction. The guide bars 9 are slidably engaged with the guide groove 10. When the bracket 3 is in a moving state, the guide bars 9 are in the guide groove 10 and move smoothly in a straight line along the predetermined trajectory of the guide groove 10. This can effectively limit various unnecessary shaking, offset or torsion and other unstable phenomena that may occur during the movement of the bracket 3, and ensure that the bracket 3 maintains straightness and stability throughout the entire movement.

[0034] See Figure 2 and Figure 3 As shown, the lifting assembly 5 includes a second stepper motor 51. The output end of the second stepper motor 51 is connected to a second lead screw 52 through a reducer. A connecting frame 8 is installed on the outside of the second lead screw 52 through a nut seat. The connecting frame 8 is connected to the lifting platform 6. When the second stepper motor 51 is started, the second lead screw 52 can be rotated by the second stepper motor 51, thereby realizing the lifting of the lifting platform 6 installed on the connecting frame 8, thus realizing the rapid adjustment of the height of the lifting platform 6.

[0035] Example 2

[0036] Please see Figure 5 As shown, this embodiment is an extension based on embodiment 1. The toilet seat 7 includes two seat plates 71 and two mounting plates 72. The two seat plates 71 are fixed in parallel between the two mounting plates 72. The mounting plates 72 are provided with square grooves. The toilet seat 7 fits into the lifting platform 6 through the grooves. An insert 12 is fixed on the lower end face of the mounting plate 72. The upper end face of the lifting platform 6 is provided with a groove 11. The insert 12 is inserted into the groove 11.

[0037] As described above, when installing the toilet seat 7 on the lifting platform 6, the mounting plate 72 can be placed on the lifting platform 6, and the insert 12 can be embedded into the corresponding groove 11. This strictly limits the horizontal movement of the toilet seat 7. Whether it is subjected to slight external force collisions or friction during daily use, or lateral external force interference caused by the user's body movements, the toilet seat 7 can always maintain its stable position on the lifting platform 6 and will not easily shift, slide or shake horizontally.

[0038] When removing the toilet seat 7 for cleaning, simply lift the toilet seat 7 to disengage the insert 12 from the groove 11. This allows for easy and quick separation of the toilet seat 7 from the lifting platform 6, making the process convenient and time-saving.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
