[0041] The technical solution of the utility model is now further described in conjunction with the accompanying drawings.

[0042] like Figure 1 and Figure 2 As shown, this embodiment discloses an electric lifting toilet seat, which is mounted on a toilet ceramic body when in use, and mainly comprises: a toilet seat 1, a fixed body 2 for supporting and fixing the toilet seat 1, handrails 3 movably and rotatably arranged on both sides of the toilet seat 1, a lifting assembly 4 arranged inside the fixed body 2 and a foot 5 arranged at the lower end of the fixed body 2, and the lifting assembly 4 is arranged inside the fixed body 2 through a housing 21. The toilet seat 1 can be a commercially available intelligent toilet seat or an ordinary plastic toilet seat.

[0043] like Figure 2 and Figure 4 As shown, the lifting assembly 4 of this embodiment includes a power source mechanism 41, a drive motor 42, a hollow part 43, a gear 44, a telescopic connection member 45, and a baffle 46; the power source mechanism 41 is used to provide power to the drive motor 42, so that the drive motor 42 can drive the hollow part 43 to rise and fall through the telescopic connection member 45. The power source mechanism 41 of this embodiment includes but is not limited to a battery or an external power supply. The control switch is set on the armrest 3, and the control switch is connected to the power source mechanism 41 and the drive motor 42 through a signal line, and is used to control the drive motor 42.

[0044] One end of the telescopic connecting member 45 of this embodiment is fixedly connected to the action end of the driving motor 42, and the other end of the telescopic connecting member 45 extends upward and passes through the hollow member 43 and is fixed to the upper end of the hollow member 43; Figure 5 , Figure 6 and Figure 7 As shown, the hollow part 43 of this embodiment is a hollow cavity with an arc-shaped structure, and the rear side of the hollow part 43 is an opening structure. When the hollow part 43 rises, the opening structure can prevent the hollow part 43 from touching the telescopic connecting part 45; the upper end of the hollow part 43 is fixed to the toilet seat 1 and the armrest, and the lower end of the hollow part 43 is a free end.

[0045] like Figure 4 As shown, in this embodiment, the side close to the driving motor 42 is the inner side, and a convex point 49 is provided on the inner side of the lower end of the hollow part 43. At the same time, the present application is provided with a nylon sheet 48 on the housing 21, and the setting position of the nylon sheet 48 on the housing 21 corresponds to the inner side of the hollow part 43. In other words, during the lifting process of the hollow part 43, left and right shaking may occur. When left and right shaking occurs, the convex point 49 abuts against the nylon sheet 48, thereby resisting the left and right shaking of the hollow part 43. And in order to solve the shaking caused by the hollow part 43 being too long during the lifting process, the present embodiment is provided with guide wheels 44 in pairs on both sides of the upper end of the hollow part 43. The guide wheels 44 contact the outer edge of the hollow part 43, guide the lifting of the hollow part 43, and thus control the lifting of the toilet seat 1. In order to ensure the stability of the toilet seat 1 during the lifting process, the present application is provided with two guide wheels 44 on the inner side of the hollow part 43 and two guide wheels 44 on the outer side of the hollow part 43.

[0046] like Figure 2 and Figure 8 As shown, in order to further reduce the left-right shaking, in this embodiment, a plurality of protrusions 47 are provided on the baffle 46 , and the protrusions 47 are matched with the grooves 22 provided on the housing 21 .

[0047] The driving motor 42 drives the telescopic connecting member 45 upward. When the telescopic connecting member 45 moves upward, the hollow member 43 rises synchronously. Since the hollow member 43 is an arc-shaped structure, the toilet seat 1 will be driven to rise and tilt forward during the rising process of the hollow member 43. When descending, the hollow member 43 and the telescopic connecting member 45 descend synchronously to achieve the descent and return of the toilet seat 1. In this embodiment, guide wheels 44 are provided on both sides of the hollow member 43. On the one hand, they are used to limit the hollow member 43 so that the hollow member 43 will not swing left and right at will in the horizontal direction, so that the toilet seat 1 can only move in one direction, ensuring stable lifting; on the other hand, the guide wheels 44 are in contact with the surface of the hollow member 43 to guide the lifting assembly 4 up and down.

[0048] In order to take into account different installation heights, the foot 5 of this embodiment is a height-adjustable structure.

[0049] Specifically, in some embodiments, the above-mentioned structural parts are all surrounded by injection molding parts, which greatly improves the safety and durability of the electric lifting toilet seat of this embodiment.

[0050] In this embodiment, the armrest 3 can be adjusted from 0 to 83 degrees to facilitate the user's entry and exit. Figure 2 As described, the armrest 3 of the present embodiment is connected to the upper end of the hollow member 43 via the armrest connecting seat 31, and the armrest 3 can be adjusted within the armrest connecting seat 31 by 0-83 degrees. The armrest connecting seat 31 adopted in the present embodiment is a U-shaped member, in which the armrest 3 is placed. Specifically, in the present embodiment, a damper 32 is arranged at the axis of the armrest, and the damper 32 enables the armrest to stop arbitrarily during the process of being lifted or lowered by the user. At the same time, a limiting mechanism is arranged inside the armrest connecting seat 31, and the limiting mechanism includes a hollow annular opening 34 and a limiting column 33, which are used to limit the upward and downward adjustment angles of the armrest 3. Specifically, the hollow annular opening 34 is arranged at the end of the armrest 3 and is arranged around the axis of the armrest. One end of the limiting column 33 passes through the armrest connecting seat 31 and the hollow annular opening 34 in sequence and is fixed to the end of the armrest 3. Fig.12 As shown, in order to facilitate the entry and installation of the left and right axes of the damper 32, the present embodiment provides a folding groove 35 on the armrest connecting seat 31. The folding groove 35 is composed of a horizontal groove and a vertical groove, which can not only ensure the quick installation of the damper 32, but also fix the damper 32. The electric lifting toilet seat disclosed in the present embodiment uses rounded plastic as the exterior surface, and there are no sharp metal parts exposed from beginning to end, reducing the risk of users being injured during use. At the same time, loose skin and male genitals are easily pinched between the seat and the ceramic basin body of the toilet during the descent process. The toilet seat 1 of the present embodiment is wide enough to surround the ceramic basin body downward, so pinching can be avoided. Fig.13As shown, when the toilet seat 1 drops to the bottom, a gap of about 10-15 mm is still retained between the toilet seat 1 and the fixed body 2 to achieve anti-pinch effect.

[0051] The armrest 3 of the present embodiment is wrapped with high-strength plastic, and has the advantages of good touch and easy cleaning. The fixed body 2 of the present embodiment is a box structure with rounded corners, and has the advantages of stable structure and no safety hazards.

[0052] The drive motor, toilet seat, switch button and other purchased parts used in this embodiment all reach IPX6 waterproof level. In addition, the fixed body of this embodiment is a plastic part, which is spliced ​​with mortise and tenon joints. The joint itself is a water guide. In addition, a water guide hole is left at the bottom of the fixed body 2. Even if water enters, it will be discharged through the water guide hole. Other metal parts are all made of stainless steel and surface treated.
