DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways defined and covered by the claims.

[0028] As Figures 1-6As shown in the figure, an embodiment of the present invention discloses a multifunctional toilet for a nursing bed chair. The multifunctional toilet is installed below the nursing bed chair and includes a bucket body 1, a bucket body lifting mechanism 2, a perineum flushing pipe 3, and an anal cleaning mechanism 4. When not in use, the bucket body lifting mechanism 2 drives the bucket body 1 to descend. When in use, the bucket body lifting mechanism 2 drives the bucket body 1 to ascend. The perineum flushing pipe 3 is arranged towards the perineum of the user and is used for spraying water to clean the urination position of the patient. The anal cleaning mechanism 4 can wipe and clean the anus and perform automatic cleaning work after the patient defecates. Specifically, the bucket body lifting mechanism 2 is installed on the lower side of the bucket body 1. Among them, the bucket body lifting mechanism 2 includes a lifting drive motor 17, a screw sleeve 18, and a screw rod 19. The output shaft of the lifting drive motor 17 is provided with a worm 20. The outer part of the screw sleeve 18 is a worm gear structure, and the worm 20 is in transmission connection with the teeth outside the screw sleeve 18. The lower end of the screw rod 19 is threadedly sleeved with the screw sleeve 18, and the upper end is pivotally connected to the bucket body 1. When the lifting drive motor 17 operates, the screw sleeve 18 can rotate, and then it can drive the screw rod 19 to drive the bucket body 1 to ascend or descend, so that the bucket body 1 can fit the buttocks of the patient, thereby avoiding the splashing of excrement or the overflow of irritating odors. The perineum flushing pipe 3 is arranged at the front end of the bucket body 1, and the perineum flushing pipe 3 penetrates from the lower side of the bucket body 1 into the inner cavity 5 of the bucket body 1. Both sides of the inner cavity 5 are provided with air blowing pipes 31 for blowing hot air or cold air. The air blowing pipes 31 are provided with air blowing ports 32 to dry or bake the anus after cleaning. The anal cleaning mechanism 4 is arranged at the rear end of the bucket body 1. The anal cleaning mechanism 4 includes an anal cleaning pipe 6 and a telescopic and rotary drive mechanism for driving the anal cleaning pipe 6 to stretch and clean the anus and rotate and store. When the user finishes defecating, the cleaning pipe rotation motor 30 of the telescopic and rotary drive mechanism drives the sleeve 10 to rotate outward by 90 degrees. Then, when the cleaning pipe telescopic motor 11 of the telescopic and rotary drive mechanism drives the anal cleaning pipe 6 to extend, the work of wiping and cleaning the anus is completed through the end interface of the anal cleaning pipe 6 (the perineum flushing pipe 3 simultaneously flushes the urine in the perineum, etc.). One end of the anal cleaning pipe 6 located in the inner cavity 5 is provided with a water outlet hole 7 that can discharge water upward, and the other end is provided with a water inlet 8. After cleaning, hot air or cold air is blown out through the air blowing port 32 arranged on one side of the inner cavity 5 to dry the anus and the perineum. Thus, while spraying water, the anus is wiped, improving the cleaning degree and cleaning efficiency of the anus, and completely eliminating the need for nursing staff to intervene, avoiding irritating the shame and self-esteem of the patient.

[0029] In this embodiment, in order to better wipe the anus, one end of the anal cleaning tube 6 located in the inner cavity 5 is an elastic hose portion 9 formed of a flexible material, such as medical soft silicone, which will not harm the anal structure. The elastic hose portion 9 is arranged to incline upward, so as to assist in achieving the scraping effect and the anal cleaning effect is better. For the sleeve 10, the cleaning tube telescopic motor 11 and the cleaning tube rotating motor 30 on the telescopic and rotating drive mechanism, when specifically arranged, the other end of the anal cleaning tube 6 is slidably connected in the sleeve 10. The sleeve 10 is provided with driven teeth, and the gear on the output shaft of the cleaning tube telescopic motor 11 meshes with the driven teeth. Of course, the same function can also be achieved by other telescopic drive mechanisms. The sleeve 10 and the output shaft of the cleaning tube rotating motor 30 are slidably connected up and down through splines. At the same time, a spring 29 that abuts against the sleeve 10 is arranged on the output shaft of the cleaning tube rotating motor 30, so as to ensure that the anal cleaning tube 6 can flexibly fit the anal positions of different users through the spring 29. When the anal cleaning mechanism 4 rotates to the storage state, the excrement is prevented from contaminating the anal cleaning tube 6 by the arc-shaped baffle 28 fixed on the sleeve 10.

[0030] In this embodiment, in order to expand the flushing range of the perineum flushing tube 3, a perineum flushing tube omnidirectional swinging mechanism is further included. The perineum flushing tube omnidirectional swinging mechanism includes a left-right swinging component and an up-down swinging component. The left-right swinging component is installed on the barrel body 1, the up-down swinging component is installed on the left-right swinging component, and the perineum flushing tube 3 is installed on the left-right swinging component. Specifically, the left-right swinging component includes a left-right yaw motor 12, the up-down swinging component includes an arc-shaped slide rail 13 and an up-down swinging motor 14. The arc-shaped slide rail 13 is installed on the left-right yaw motor 12, and the perineum flushing tube 3 is installed on the up-down swinging motor 14, and the up-down swinging motor 14 moves along the arc-shaped slide rail 13.

[0031] In this embodiment, in order to ensure the sealing performance at the connection between the perineum flushing tube 3 and the barrel body 1, a through hole 15 for the perineum flushing tube 3 to penetrate is provided on the barrel body 1. An elastic rubber body 16 is sleeved in the through hole 15. The elastic rubber body 16 is in a compressed state. The perineum flushing tube 3 is hermetically penetrated through the elastic rubber body 16, and the elastic rubber body 16 will closely fit the perineum flushing tube 3, so as to achieve the sealing effect.

[0032] In this embodiment, in order to ensure the precise guidance during the rising process of the barrel body 1 and prevent the influence of the eccentric load of the barrel body 1, a guide rod 21 and a guide slide block 22 are further included. The guide rod 21 is vertically and fixedly installed on the nursing chair, and the guide slide block 22 is installed on the barrel body 1 and is slidably connected with the guide rod 21 through the internal chute.

[0033] In this embodiment, taking into account the uncertainty of the flow direction of urine during urination, a urine shield 23 and a shield rotating motor 24 are also included that are installed on the barrel body 1. The urine shield 23 is set at the front end of the barrel body 1, so that once the urine passes over the upper end of the barrel body 1, it can be blocked by the urine shield 23. The shield rotating motor 24 drives the urine shield 23 to rotate and be stored in the inner cavity 5 or set vertically, that is, when not in use, the urine shield 23 can be rotated to the inside of the inner cavity 5 by the shield rotating motor 24.

[0034] In this embodiment, it also includes a barrel cover 25, a parallel four-bar mechanism 26 and a cover drive motor 27. The barrel cover 25 is arranged on both sides of the barrel body 1 and is a split-type structure. One end of the parallel four-bar mechanism 26 is hinged to the barrel cover 25, and the other end is connected to the cover drive motor 27 to close or open the space above the barrel body 1. When the barrel body 1 is used up, the barrel body lifting mechanism 2 drives the barrel body 1 to descend. At this time, the cover drive motor 27 is activated to drive the barrel body cover 25 to move relative and upward, closing the isolation barrel body 1, thereby realizing the patient's lying function.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
