Description

A mobile toilet for the elderly

Technical field:

The invention relates to the field of toilets, in particular to a mobile toilet for the elderly.

Background technology:

The number of elderly people in my country is growing rapidly. The living problems of the elderly have become an important social issue and an important design issue. Whether the elderly can be provided with comfortable and humanized facilities to meet their actual needs in life has also been increasingly concerned and valued by many aspects of society. Relevant experts believe that there are many problems with the facilities related to the elderly due to relevant pension policies, management regulations, design research and other factors. With the major challenges faced by elderly care, living and life, the design problems of elderly facilities in my country need to be solved as soon as possible. In daily life, toilets play an important role in bathroom facilities. As a special group of people, most of the elderly have weak physical activity, inconvenience in movement, and stay at home for a relatively long time. Therefore, the ease of use, practicality, safety and comfort of toilets are particularly important to them. However, today, toilets for the elderly that are safe, functional, healthy, and environmentally friendly are still rare in the market, and cannot provide more affectionate and humanized services for the elderly. Moreover, the products for the elderly on the market are uneven and cannot keep up with market changes.

Universal toilets can meet the needs of both normal people and the elderly with good mobility. In some places where elderly people live in large numbers, considering the number of elderly people living there, the complex and changeable physical and mobility conditions, and at the same time reducing the workload of caregivers and improving the elderly's ability to take care of themselves, safety handrails are installed next to the toilets to facilitate the use of elderly people with poor legs and feet, which can meet the different needs of elderly people with good mobility to a certain extent. However, the device requires the elderly to use their arm strength to squat and stand up. If the elderly's palm slips out of the handrail, the consequences will be disastrous.

Summary of the invention:

The purpose of the present invention is: the present invention is a mobile toilet for the elderly designed for the elderly living alone, which can assist the elderly to go to the toilet and reduce the risk of the elderly falling when going to the toilet; at the same time, the toilet frame can move up and down, and the toilet can be moved by the wheels at the bottom of the toilet, especially for the night time, avoiding the elderly to walk to the toilet, thereby reducing the risk of the elderly falling when going to the toilet at night; further, the toilet can lock the handrail, reducing the risk of the elderly falling due to the rotation of the handrail due to excessive pressure on the handrail when standing up and sitting down. The interior of the toilet can isolate the odor of urine, thereby improving the quality of life of the elderly.

In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: the present invention comprises a moving lifting device (1), a sliding pushing device (2), an auxiliary sitting device (3), and a supporting armrest device (4).

The specific operation process is as follows: when using the mobile toilet for the elderly at night, the elderly first wake up the toilet, and the profile three (21) contacts the ground before waking up. After waking up, the electric push rod one (17) of the mobile push-lift device (1) extends out. Since the electric push rod one (17) is connected to the lower connecting plate (16) of the electric push rod, the lower connecting plate (16) of the electric push rod is connected to the profile two (19), and the profile two (19) is connected to the profile one (13) through the angle code (14). The first (13) is connected to the motor support connecting plate (100), the motor support connecting plate (100) is connected to the motor support (12), the motor support (12) is connected to the motor (11), and the motor (11) is connected to the wheel (10), so that the wheel (10) starts to contact the ground, and the profiles three (21), four (22), five (23), and six (24) connected by the angle code (14) are lifted as a whole, so that only the wheel (10) of the entire toilet is on the ground. After the toilet is lifted as a whole, the motor (11) drives the wheel (10) to rotate, so that the toilet is moved as a whole and reaches the elderly according to the planned route. After reaching the elderly, the electric push rod one (17) of the moving push device (1) is retracted, the wheel (10) leaves the ground, and the profile three (21) starts to contact the ground, thereby achieving a larger contact area, preventing the toilet from tipping over due to the small contact area between the toilet and the ground when the elderly use the toilet.

After the profile 3 (21) begins to fully contact the ground, the stepper motor 1 (208) begins to rotate, driving the gear (206) to rotate. Since the gear (206) is meshed with the rack (205), the rack (205) is connected to the rack connecting plate (204), the rack connecting plate (204) is connected to the slide (203), the slide (203) is connected to the slide connecting plate (26), the slide connecting plate (26) is connected to the guide rail (27), the guide rail (27) is connected to the slider (28), the slider (28) is connected to the urinal support plate (29), the bottom of the urinal (200) is bonded to the urinal support plate (29), the urinal support plate (29) is positioned with the slider connecting plate (26) through the stop pin (20), and thus the urinal (200) is driven to move forward. 00) contacts the lower end of the toilet trough (214) and the side of the rotating baffle (201), the threaded sleeve (223) is embedded in the hole below the toilet trough (214), the spring (222) is embedded in the groove below the toilet trough (214), the rotating baffle (201) is located above the baffle screw (213), fits with the lower end of the toilet trough (214), and is loosely sleeved on the baffle screw (213), and the baffle screw (213) is connected to the toilet trough (214) through the threaded sleeve (223); therefore, the forward movement of the urinal (200) will force the rotating baffle (201) to rotate, and the rotating baffle (201) will compress the spring (222) during the rotation process, and finally the top round opening of the urinal (200) will overlap with the bottom round opening of the toilet trough (214), so as to achieve the purpose of introducing the urine of the elderly into the urinal (200). The rotation of stepper motor 1 (208) also drives synchronous pulley 1 (209) to rotate. The rotation of synchronous pulley 1 (209) drives synchronous pulley 2 (212) through synchronous belt 1 (210). Since synchronous pulley 2 (212) and synchronous pulley 4 (219) are both connected to shaft 1 (211), synchronous pulley 2 (212) drives shaft 1 (211) to rotate, thereby driving synchronous pulley 4 (219) to rotate. The rotation of synchronous pulley 4 (219) drives synchronous belt 1 (210). The second (215) drives the synchronous pulley three (217) to rotate. Since the synchronous pulley three (217) and the profile eight (216) are both connected to the second shaft (220), the synchronous pulley three (217) will drive the second shaft (220) to rotate, thereby driving the profile eight (216) to rotate. The cover (218) is connected to the profile eight (216), so that the cover (218) is finally rotated to achieve the purpose of opening the toilet cover, providing space for the auxiliary sitting device (3) to move.

After the cover (218) rotates 90 degrees, the stepper motor 1 (208) stops rotating. The electric push rod 2 (33) and the electric push rod 3 (37) extend simultaneously. Since the profile 10 (31) is connected to the profile 4 (22) through the angle code (14), the profile 11 (310) is connected to the profile 10 (31) through the angle code (14), the electric push rod bracket 1 (32) is connected to the profile 10 (31) and the profile 11 (310), the electric push rod bottom plate (36) is connected to the profile 10 (31) and the profile 11 (310), the electric push rod 2 (33) is connected to the electric push rod bracket 1 (32), and the electric push rod 3 (37) is connected to the electric push rod bottom plate. (36) is connected, so the bottom of the electric push rod two (33) and the electric push rod three (37) are fixed; because the seat cushion support plate (35) is connected to the electric push rod bracket two (34), the electric push rod bracket two (34) is connected to the electric push rod two (33) through the shaft four (39), and the electric push rod bracket two (34) is connected to the electric push rod three (37) through the shaft three (38), the seat cushion support plate (35) will rise with the extended parts of the electric push rod two (33) and the electric push rod three (37), so as to achieve the purpose of lifting the support armrest device (4).

When the supporting handrail device (4) rises to a suitable height, the electric push rod 2 (33) and the electric push rod 3 (37) stop extending. The stepper motor 2 (48) starts to rotate. Since the coupling 2 (412) connects the shaft of the stepper motor 2 (48) and the shaft 5 (49), the profile 12 (43) is connected to the profile 13 (47) through the profile connecting plate (44), and the profile 12 (43) is also connected to the shaft 5 (49). Therefore, the rotation of the stepper motor 2 (48) drives the coupling 2 (412) to rotate, the rotation of the coupling 2 (412) drives the shaft 5 (49) to rotate, and the rotation of the shaft 5 (49) drives the profile 12 (43) to rotate, and finally the rotation of the profile 13 (47) is realized to achieve the purpose of supporting the hands of the elderly, further reducing the risk of falling due to insufficient hand strength when the elderly use the toilet. Furthermore, in order to prevent the profile 12 (43) from rotating due to the elderly grasping and supporting it, the reduction motor (403) starts to rotate. Since the coupling 1 (404) connects the shaft of the reduction motor (403) and the screw rod (407), the nut flange (405) is connected to the screw rod (407) through a thread, the sliding pin (406) is connected to the nut flange (405) through a screw, and the groove below the sliding pin (406) fits with the protrusion in the fixing seat (409) on the sliding pin, and the long flange (42) is connected to the sliding pin (406) through a screw. Finally, the reduction motor (403) drives the coupling 1 (404) and the screw rod (407) to rotate, and the nut flange (405), the sliding pin (406), and the long flange (42) move axially at the same time, so that the protruding outer circle of the long flange (42) is inserted into the hole inside the profile 12 (43), thereby achieving the purpose of limiting the rotation of the profile 12 (43) due to force.

After all the above steps are completed, the elderly person sits on the cushion (45) and places his hands on the profile 13 (47). After the elderly person is ready, he issues a command to start using the toilet. At this time, the electric push rod 2 (33) and the electric push rod 3 (37) are retracted at the same time, and the support armrest device (4) is lowered together with the elderly person. When the electric push rod 2 (33) and the electric push rod 3 (37) are lowered to a height that the elderly person finds appropriate, the electric push rod 2 (33) and the electric push rod 3 (37) stop moving at the same time, and the elderly person starts to urinate.

After the elderly person finishes urinating, he/she issues a command to end the toileting. At this time, the second electric push rod (33) and the third electric push rod (37) extend simultaneously, raising the support armrest device (4) together with the elderly person. After rising to a suitable height, the second electric push rod (33) and the third electric push rod (37) stop moving simultaneously. The elderly person gently pushes the profile thirteen (47) with both hands, and the buttocks leave the cushion (45), and the elderly person's toileting action is completed.

After the elderly person leaves the toilet, the reduction motor (403) rotates in the reverse direction, and the long flange (42) leaves the hole inside the profile twelve (43), and no longer restricts the rotation of the profile twelve (43). The stepper motor two (48) rotates in the reverse direction, and the profile twelve (43) rotates to be parallel to the ground. The electric push rod two (33) and the electric push rod three (37) retract to the starting position at the same time, driving the support armrest device (4) to the lowest position.
