[0038] The electric push rod 302 can be a common electric telescopic rod or a linear motor in the prior art.

[0039] In this embodiment, the rear end connecting rod 206 and the lower end connecting rod 207, the lower end connecting rod 207 and the outer wall of the H-shaped structure of the front end fixing frame 201, the rear end connecting rod 206 and the upper end connecting rod 205, the upper end connecting rod 205 and the top of the upper support foot of the H-shaped structure of the front end fixing frame 201, and the upper end connecting rod 205 and the auxiliary rod 301 or the electric push rod 302 are all rotatably connected through pin shafts.

[0040] In summary, the working method of this embodiment is as follows:

[0041] Move the device to the use position, first adjust the front fixing frame 201 up and down to the specified height according to the height of the toilet, rotate the bracket 101 so that the fixed suction cup 1011 on it is parallel to the ground, and extract the air inside the fixed suction cup 1011 to complete the fixation of the device at the corresponding position of the toilet.

[0042] Start the electric push rod 302 to slowly extend it, and the upper end of the electric push rod 302 drives the upper connecting rod 205, and under the linkage cooperation of the upper connecting rod 205, the rear connecting rod 206, and the lower connecting rod 207 (equivalent to a four-bar linkage), the seat plate 203 rises and tilts toward the user, and the odor-proof partition 202 slowly leaves the toilet, and the first spring 3011 inside the auxiliary rod 301 extends to assist the electric push rod 302.

[0043] When the electric push rod 302 reaches the travel limit, the seat plate 203 reaches the maximum inclination angle and the maximum height. At this time, the top surface of the seat plate 203 forms a bearing surface (not marked) for the user to lean on. The user can lean on the seat plate 203 and hold the armrest 204 during the leaning process.

[0044] When the user leans firmly, the electric push rod 302 is started to descend. At this time, under the linkage cooperation of the upper connecting rod 205, the rear connecting rod 206, and the lower connecting rod 207, the seat plate 203 is driven to descend and the inclination angle is reduced. The first spring 3011 inside the auxiliary rod 301 is compressed to balance the force on the mechanism.

[0045] When the electric push rod 302 reaches the minimum limit, the upper surface of the seat 2 reaches a horizontal position, and the odor-proof partition 202 is close to the toilet to prevent odor from overflowing.

[0046] When the user finishes using the toilet, the electric push rod 302 is activated to extend, so that the seat 2 rises and tilts to a leaning position, helping the user to get up from the toilet, and the user completes a single use of the device.

[0047] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
