Description

Technical Field

[0001] The invention relates to a toilet, in particular to an electric height-raising toilet lifting aid. Background Art

[0002] A toilet is a sanitary appliance in the field of building water supply and drainage materials. It is a toilet characterized by the human body sitting in a sitting position when in use. Existing toilets, whether direct flush or siphon type, do not have the function of automatic lifting. People need to stand up by themselves after using. If there are elderly people or patients with limited mobility at home, some handrails are generally installed on the wall to facilitate standing up after using the toilet. However, this still requires arm strength, which is still very inconvenient for the elderly or patients. For this reason, toilet chairs that can automatically lift and lower have also appeared on the market.

[0003] After investigation, the existing Chinese patent No. 201510192930.6, "An Intelligent Safety Electric Lifting Power-Assisted Commode Chair", includes three parts: a commode chair, a lifting device and a controller. The commode chair is composed of a backrest, armrests, a saddle and a commode chair frame. The saddle is located above the toilet, and the leakage hole on the saddle is consistent with the opening position of the toilet; the lifting device includes an electric lifting rod I on the front side of the commode chair and electric lifting rods II on both sides of the commode chair, wherein the upper ends of the electric lifting rods I and II are respectively fixedly connected to the commode chair frame, and the lower ends of the electric lifting rods I and II are both fixed on the base, and the electric lifting rods I and II are both electrically connected to the controller. This structure is to set a commode chair on the toilet to help people get up after defecation, but the structure is complex, the volume is large, and the cost is high.

[0004] In addition, the Chinese patent No. 201510565681.0, "A Power-Assisted Toilet Chair", includes a chair frame, a toilet seat, a power mechanism and a connecting rod mechanism. The power mechanism has a retractable movable rod, which is installed on the chair frame, and the free end of the movable rod is movably connected to the toilet seat to drive the toilet seat to rise or fall; the connecting rod mechanism is connected to the chair frame and the toilet seat, and the connecting rod mechanism is used to control the toilet seat to achieve a vertical lifting mode or switch to a tilting lifting mode. This structure is to install a toilet chair on the toilet, and the lifting of the toilet seat on the toilet chair plays a power-assisting role, but the structure is also relatively complex, the volume is also large, and the cost is high. .

A button connected to the control system for controlling the extension and retraction of the electric push rod 5 is arranged on the inner side of the lower end of the armrest 20. The control system also includes a delay module. When the toilet seat cover is raised, it will automatically reset within a set time delay; mounting holes fixed to the toilet 1 are opened on the front and back sides of the base plate 8, wherein the mounting hole on the front side of the base plate 8 is a longitudinal waist-shaped hole, and a fixing screw 30 passes through the base plate 8 and is connected to the toilet 1. The mounting holes on the rear side of the base plate 8 are two transverse waist-shaped holes 82, which are fixedly connected to the toilet 1 by two large flat head screws 40, and are suitable for application on toilets of various models.

[0033] When in use, after relieving oneself on the toilet 1, one only needs to lightly press the button below the armrest 20, and the electric push rod 5 will drive the heightening frame 2, the toilet seat 3, the cover plate 4 and the armrest 20 to rise together, so that the user can stand up easily. At the same time, the heightening frame 2, the toilet seat 3, the cover plate 4 and the armrest 20 will automatically reset after a delay (the delay time can be set as needed). In this way, the user can stand up and sit down very conveniently and comfortably, solving the problem of the elderly, pregnant women and people with mobility difficulties standing up conveniently after relieving themselves.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
