Description

Technical Field

[0001] The invention relates to the technical field of bathroom robots, and in particular to an intelligent toilet robot. Background Art

[0002] In the last few years or even twenty or thirty years of their lives, the elderly will experience symptoms such as physical inconvenience, semi-disability, slow movements, and difficulty going to the toilet and defecating. Semi-disabled elderly people, patients, people with Alzheimer's disease, and some frail elderly people cannot or can barely go to the toilet independently, and their movements are slow. Elderly people, patients, and semi-disabled people with physical disabilities need the help of others to move from the bedroom to the bathroom, and defecation is very inconvenient. In more serious cases, the bedroom and bathroom are far apart, and they may become incontinent or urinate during the transfer due to the long transfer time. It can be seen that it is a great burden for elderly people, patients, and semi-disabled people with physical disabilities to go to the toilet independently, and it is even more difficult to go to the toilet at night.

[0003] Therefore, it is a practical demand for the elderly, patients, and semi-disabled people with physical disabilities to go to the toilet by the bed in the bedroom. The development of equipment to help the elderly, patients, and semi-disabled people with physical disabilities solve the problem of going to the toilet is an urgent problem that society needs to solve. People with physical disabilities are eager to use the flush toilets they are used to in life like normal people to solve defecation and urination. At present, relying on advanced solution technologies, some solutions have been developed at home and abroad, such as using a transport robot to transfer the elderly to the bathroom and use the toilet in the bathroom. However, the transport robot has great power, there is a hidden danger of accidental injury to the human body, and the cost is high, making it difficult to promote and popularize. The more common solutions are a bedpan and a mobile plastic toilet. However, using a bedpan is directly exposed to the air, and the odor will be directly spread in the indoor space environment. The mobile plastic toilet is a portable device for cars and needs to be flushed with water. The overall weight is large, it is inconvenient to carry it manually, and the defecation odor is also directly spread in the indoor space environment. The odor is spread in the indoor space environment, attached to the surface of walls, clothes, furniture, and textiles. Even if it is ventilated frequently, there will still be obvious odor in the room. Moreover, toilet paper is needed for defecation and cleaning, and the used toilet paper must be placed in a plastic bag and discarded separately, which affects indoor hygiene and pollutes the environment.

[0113] The intelligent toilet robot in the embodiment of the present invention can be freely transferred between the bedroom and the bathroom by relying on the mobile system. The toilet system is used for defecation in the bedroom, and sewage is discharged through the sewer system in the bathroom, thereby achieving the purpose of using the toilet to solve the problem of defecation and urination in areas other than the bathroom, meeting the normal toilet needs of the elderly, patients, and semi-disabled people with physical disabilities, helping the elderly, patients, and semi-disabled people with physical disabilities to obtain the same defecation method as healthy people, and is highly convenient to use.

[0114] In some embodiments, based on the above embodiments, the preset distance is 10-30 mm.

[0115] Specifically, the preset distance is the above-mentioned safe distance, preferably 10 mm, 15 mm, 20 mm, 25 mm and 30 mm. The specific size can be determined according to the volume and use environment of the intelligent toilet robot in the embodiment of the present invention.

[0116] In some embodiments, based on the above embodiments, the moving wheel structure includes a fixed universal wheel and an electric telescopic universal wheel 134, the fixed universal wheel is arranged on the lower surface of the mobile platform, and the electric telescopic universal wheel 134 is arranged on the upper surface of the mobile platform. When the intelligent toilet robot moves, the wheel of the electric telescopic universal wheel 134 extends downward, and when the intelligent toilet robot is stationary, the wheel of the electric telescopic universal wheel 134 retracts upward.

[0117] Specifically, the mobile system is composed of a mobile platform, a three-dimensional frame and a mobile wheel structure.

[0118] The mobile platform is a basic frame or basic platform, and has two upper and lower surfaces. The upper surface is used to support and install equipment such as the side-row toilet 210, the crusher 138, the water pump 136, the electric telescopic universal wheel 134, the electric handrail 133, and the 220V / 24V power adapter 119. The lower surface is equipped with a fixed universal wheel, which supports the mobile platform and realizes the movement of the mobile platform.

[0119] The three-dimensional frame is bolted or welded to the mobile platform and is the three-dimensional installation foundation of the equipment. It is used to support and install the septic tank 213, the clean water tank 203, the air treatment box 220, the air-water separator 219, the water supply distributor 204, the fan 132, the water inlet 201, the shrink cable drum 117, the leakage protection air switch 118, the controller 100 and various electric ball valves, solenoid valves, power supply sockets and other equipment.

[0120] In some embodiments, based on the above embodiments, the wheel of the fixed universal wheel is 5-8 inches, and the wheel of the electric telescopic universal wheel 134 is 2 inches.

[0121] Specifically, the wheels of the fixed universal wheels are preferably 5 inches, 6 inches, 7 inches and 8 inches. The specific size can be determined according to the volume and use environment of the intelligent toilet robot in the embodiment of the present invention.

[0122] Specifically, the intelligent toilet robot adopts wheeled movement, and there are two optional wheel train structures, namely fixed universal wheels and electric telescopic universal wheels 134. One of them is selected according to user requirements and fixed to the surface of the mobile platform with bolts. Among them:

[0123] Fixed universal wheels, that is, ordinary universal wheels, are universal accessories, commonly found in airports or shopping luggage carts, trolleys, etc., with a full range of categories and flexible choices. The fixed universal wheels are fixed and installed under the mobile platform with bolts. The mobile platform can be moved by manual pushing. Fixed universal wheels will raise the smart toilet robot. If the diameter of the wheel is too small, the movement resistance is large, and it is difficult to cross the sliding door track. If the diameter of the wheel is too large, the toilet is too high, which can easily cause inconvenience to the user. In the embodiment of the present invention, the fixed universal wheel uses a 5-inch to 8-inch universal wheel.

[0124] The wheel of the electric telescopic universal wheel 134 is also a universal wheel, which is installed at the lower end of the electric telescopic mechanism. The wheel and the electric telescopic mechanism together constitute the electric telescopic universal wheel 134. The electric telescopic universal wheel 134 is installed on the mobile platform. The electric telescopic universal wheel 134 can be retracted upward and extended downward. The wheel of the electric telescopic universal wheel 134 extends downward, and the mobile platform can be moved by manual pushing. The wheel of the electric telescopic universal wheel 134 retracts upward, the mobile platform lands, and the toilet seat height is the lowest, which is convenient for use. Due to the limitation of the installation space, the wheel of the electric telescopic universal wheel 134 in the embodiment of the present invention uses a 2-inch universal wheel.

[0125] In some embodiments, based on the above embodiments, the toilet system further includes a smart toilet seat cover 140, and the smart toilet seat cover 140 is disposed above the side toilet seat 210 and is electrically connected to the control system.

[0126] Specifically, the toilet system is composed of a side-row toilet 210 and a smart toilet cover 140. Among them:

[0127] The side-discharge toilet 210 uses a side-discharge method for excretion. Usually, toilets are commonly known as toilets, and are divided into lower discharge and side discharge according to the excretion method. The lower discharge method means that the discharge port is at the bottom and discharges downward, and the side discharge method means that the discharge port is at the back and discharges horizontally. Most of the toilets installed in homes, offices, and factory buildings are of the lower discharge method, which requires the installation of sewer pipes at the bottom of the floor. A small number of modified buildings are restricted by building conditions and cannot install sewer pipes at the bottom of the floor. Sewer pipes can only be installed on the current floor or on the roof, so the side discharge method is adopted. The intelligent toilet robot in the embodiment of the present invention is mobile and cannot have a lower sewer pipe, so the side discharge method is adopted, that is, the side-discharge method is selected.
