Description

Technical Field

[0001] The invention relates to a toilet step stool. Background Art

[0002] The toilet step stool is a footstool placed in front of the toilet. The traditional step stool consists of a stool surface and a fixed-height support leg. After sitting on the toilet, the person puts his feet on the step stool and lifts the stool surface to change the angle between the thigh and the trunk, which is equivalent to sitting but squatting, making it easier to open the nodes that control defecation (scientific research shows that 35 degrees is the best), so that defecation can be smooth, the convenience time is shortened, and the chance of inducing constipation, hemorrhoids and other diseases due to long-term toilet sitting is reduced. However, due to different ages and heights, the requirements for the height of the step stool are also very different. Each family will have multiple members, including the elderly, children or pregnant women. The step stool for adults is obviously not suitable for them, so later a step stool with adjustable stool surface height appeared. For example, Chinese invention patent CN 206630537 U. However, the existing step stool with adjustable seat surface is to raise and lower the entire seat surface. Since a driving mechanism needs to be set under the seat surface, the driving mechanism has a height. Even if the seat surface is lowered to the lowest point, it is still at a certain height (at least ten centimeters) from the ground. When using it, the user needs to raise his legs and step on the seat surface, which is very laborious or impossible for the elderly and other people with mobility impairments to do it by themselves. Summary of the invention

[0003] The invention aims to provide a toilet step stool so that the lowest position of the foot pedal can be close to the ground for easy use.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a toilet step stool, including a fixed chassis, a lifting drive mechanism, an N-shaped connecting piece and two foot pedals; the bottom end of the lifting drive mechanism is fixed on the fixed chassis, the driving end of the lifting drive mechanism extends upward and is fixedly connected to the middle cross bar of the N-shaped connecting piece; the two ends of the N-shaped connecting piece extend downward and are respectively fixedly connected to one of the foot pedals; thus, the two foot pedals are arranged on both sides of the lifting drive mechanism, and are lifted up and down by the drive of the lifting drive mechanism, and have a raised position and a lowest starting position close to the ground.

[0005] The above scheme also includes a shell, which is arranged on the fixed chassis to cover the lifting drive mechanism, the foot pedal is exposed on both sides of the front of the shell, and an avoidance groove is opened on the shell corresponding to the lifting stroke of the N-shaped connecting piece.

[0006] The above scheme also includes a handrail, which is arranged above both sides of the rear end of the shell; a handrail driving mechanism is also arranged in the shell to drive the handrail to rise and fall.

[0007] In the above solution, a pedal sensor is provided on the pedal to obtain a signal indicating that the pedal is stepped on.

[0008] In the above solution, a circuit device is arranged in the shell, and the circuit device includes a control unit, and the control unit is connected to the pedal sensor to receive a signal sent by the pedal sensor indicating that the pedal sensor is being stepped on.

[0009] In the above solution, the circuit device also includes a wireless transmitting device to send signals to the outside world.

[0010] In the above solution, the circuit device also includes a wireless receiving device to receive external control instructions.

[0011] In the above solution, the circuit device also includes a timer.

[0012] In the above scheme, a weighing device is provided on the foot pedal to obtain a weight signal of the foot pedal being stepped on.

[0013] In the above solution, the lifting drive mechanism can be an electric push rod mechanism, a cylinder mechanism or a hydraulic cylinder mechanism.

[0014] The toilet step stool of the present invention is provided with a foot pedal, and the foot pedal is connected to the lifting drive mechanism through an N-shaped connecting piece, so that the foot pedal can be lowered to the lowest position and basically covered on the ground, so that the elderly and people with inconvenience in legs and feet can step on the foot pedal more easily and safely, and the use process is also more convenient and safe. In addition, since the lifting drive mechanism is located between the two foot pedals, the stability is better. BRIEF DESCRIPTION OF THE DRAWINGS
