Description

Technical Field

[0001] This invention relates to the field of nursing equipment technology, and in particular to a foot bath basin suitable for the elderly. Background Technology

[0002] As my country's population ages, the health of the elderly is receiving increasing attention. In addition to building sports facilities and encouraging physical exercise, it is also important to cultivate good lifestyle habits, such as foot baths. Regular foot baths can help dispel cold, keep warm, accelerate metabolism, reduce cardiac afterload, and improve heart function. They do not require strenuous exercise, have no venue restrictions, and can be done at home, making them particularly suitable for the elderly.

[0003] Elderly people often encounter problems when washing their feet, such as difficulty in movement, inability to lift heavy objects, inability to fetch water, lift buckets, move buckets, pour out buckets, or clean buckets. While traditional foot basins come in many styles and functions, most only serve the purpose of soaking feet and cannot effectively remove dirt from between the toes. Furthermore, washing feet requires rubbing with hands, which can cause discomfort for elderly people with limited mobility due to prolonged pressure on the abdomen. In special cases, assistance from others may be necessary. In addition, rubbing feet with hands is unhygienic if there are skin diseases on the feet. After washing, people are accustomed to drying their feet with a foot towel, which can easily lead to cross-infection and more foot diseases, causing further trouble for the elderly. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a foot bath suitable for the elderly, which can not only automatically add and drain water, but also heat and keep the water warm, and can perform rinsing, massage and drying of the feet without the need for hand intervention.

[0005] This invention is achieved through the following technical solutions:

[0006] A foot bath basin suitable for the elderly includes a basin body and a drying mechanism and a circulating flushing mechanism mounted on the basin body. The basin body has a water inlet at the upper end of its side wall and a water outlet at the lower end. A baffle plate is rotatably connected to the bottom of the basin body's inner cavity. The baffle plate has a circular structure, with several baffles evenly distributed along the circumference on its upper surface and several driving blocks evenly distributed along the circumference on its lower surface. The driving blocks are powered to rotate by a driving mechanism mounted on the basin body. The drying mechanism includes an upper ring-shaped air distribution duct and a lower ring-shaped air distribution duct. The upper ring-shaped air distribution duct is fixed to the upper opening edge of the basin body, and the lower ring-shaped air distribution duct is fixed to the bottom end of the basin body. The upper and lower ring-shaped air distribution ducts are powered by a hot air mechanism. The circulating flushing mechanism includes a water pump and a flushing pipe connected to the water pump outlet. The flushing pipe is fixed to the inner wall of the basin body, and several spray nozzles are evenly distributed on the pipe wall. In this technical solution, the water inlet can be connected to the water inlet pipe for adding water to the foot bath, and the water outlet pipe can be connected to the floor drain for draining wastewater from the foot bath. The baffle plate can be driven by a drive mechanism to rotate when the foot bath needs cleaning, causing the water in the basin to rotate and clean the inner wall of the foot bath. The drying mechanism includes an upper ring-shaped air distribution pipe and a lower ring-shaped air distribution pipe. The hot air blown out by the upper ring-shaped air distribution pipe can dry the inner wall of the basin and the feet, and the hot air blown out by the lower ring-shaped air distribution pipe can clean and dry the water accumulated on the ground near the foot bath, preventing the elderly from slipping and falling. The circulating flushing mechanism includes a water pump and a flushing pipe connected to the water pump outlet. The flushing pipe is fixed to the inner wall of the basin, and several spray nozzles are evenly distributed on the pipe wall. The water inlet of the water pump is connected to the inner cavity of the basin, and the high-pressure water flow generated can massage the feet and promote blood circulation.

[0007] Preferably, the driving mechanism includes several driving units evenly distributed along the circumferential direction at the bottom of the basin. Each driving unit includes an iron core and a heat insulation sleeve wrapped around the iron core. A coil is wound around the outer wall of the heat insulation sleeve. The driving block is a permanent magnet. An encoder for sensing the position of the permanent magnet is provided on the bottom of the basin. In this technical solution, as a mature existing motor drive technology, the coil of a single driving unit can generate a magnetic field after being energized. Several driving units can form a rotating magnetic field under the control of the control unit, directly driving the permanent magnet to rotate, eliminating the need for an intermediate transmission structure. It should be noted that when several driving units are supplied with the same high-frequency alternating current, the iron core will generate a large amount of heat under the action of eddy currents, which heats or insulates the water in the basin. The heat insulation sleeve can protect the energized coil and prevent it from being damaged at high temperatures. The encoder can detect the position of the spoiler in real time and assist the control unit in accurately controlling the direction and speed of the spoiler.

[0008] Preferably, the basin includes a bottom plate and side plates, the bottom plate and side plates are detachably connected, and the lower end of the bottom plate is provided with a mounting hole adapted to the drive unit; the iron core extends into the inner cavity of the basin; in this technical solution, the detachable connection between the bottom plate and side plates facilitates the processing and assembly of parts; the mounting hole facilitates the positioning of the drive unit; and the iron core extending into the inner cavity of the basin can directly contact the water in the basin, improving the efficiency of water heat transfer.

[0009] Preferably, the upper surface of the spoiler is provided with a plurality of rubber protrusions, which are placed between the spoilers and have their heads higher than the upper edge of the spoilers. In this technical solution, the rubber protrusions can increase the comfort of the spoiler's support for the feet. When the feet move on the rubber protrusions, they can massage the soles of the feet and promote blood circulation.

[0010] Preferably, the lower wall of the upper annular air duct is evenly distributed with several air outlets, and the outer wall of the lower annular air duct is provided with an air intake. The upper and lower annular air ducts are connected by a pipe, and a fan and an electric heating device are provided on the connecting pipe. In this technical solution, the fan and electric heating device are directly arranged in the connecting pipe. When drying feet, the upper annular air duct serves as the air outlet and can directly dry the feet, while the lower annular air duct serves as the air inlet and can create negative pressure near the bottom of the basin, causing the surrounding air to flow towards it and accelerating the drying of water on the nearby ground. It should be noted that when there is a large amount of water on the ground near the foot bath, the fan can be reversed so that the upper annular air duct serves as the air inlet and the lower annular air duct serves as the air outlet, blowing out hot air to dry the water on the ground near the foot bath.

[0011] Preferably, the flushing pipe has a ring-shaped structure; the water inlet of the water pump is located at the bottom of the basin; in this technical solution, the water pump can transport the hot water at the bottom of the basin to the top, improve the efficiency of heat exchange, and make the water temperature distribution in the basin more uniform.

[0012] Preferably, both the inlet and outlet are equipped with solenoid valves, and the bottom of the inner cavity of the basin is equipped with a liquid level sensor and a temperature sensor. In this technical solution, the liquid level sensor can sense the water level in real time, and the temperature sensor can sense the water temperature in real time. The liquid level sensor and the temperature sensor are electrically connected to the control unit of the device.

[0013] Preferably, a cleaning ball is placed in the basin; in this technical solution, the cleaning ball can be thrown towards the basin wall by centrifugal force and move close to the basin wall to clean the basin wall and improve the cleaning effect.

[0014] A control method for a foot bath basin suitable for the elderly, based on any of the above-mentioned methods, involves the following steps: When the aqueous solution inside the foot bath basin needs to be heated, the energized coils of several drive units are input with high-frequency alternating current of the same frequency under the control of the control unit, causing the iron core to generate heat; when the inner wall of the foot bath basin needs to be cleaned, the several drive units, under the control of the control unit, form a rotating magnetic field, causing the motor rotor to rotate; In this technical solution, the drive unit can be used as a "motor stator" to drive the permanent magnet to rotate, causing the turbulence disk to rotate and driving the water flow to clean the inner wall of the basin, and can also be used as a heating element utilizing the eddy current heating effect to heat or keep the water in the foot bath basin warm. This dual-purpose design reduces both the manufacturing cost and the size of the device.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The foot bath basin is equipped with an inlet and an outlet, and electromagnetic valves are installed on the inlet and outlet to realize automatic filling and drainage, reducing the labor intensity of the elderly; 2. The foot bath basin is equipped with a circulating flushing mechanism, which can accelerate the flow of water in the basin and also rinse and massage the feet without the need for hand intervention; 3. The bottom of the foot bath basin is equipped with a baffle plate, which can clean the inner wall of the basin after washing the feet; 4. The foot bath basin is equipped with a drying mechanism, which can dry the water accumulated on the feet and the ground near the foot bath basin; 5. The drive mechanism of the foot bath basin can be used as a "motor stator" to drive the permanent magnet to rotate, causing the baffle plate to rotate and drive the water flow to clean the inner wall of the basin, and can also be used as a heating element using the eddy current heating effect to heat or keep the water in the foot bath basin. It has two functions, which reduces the manufacturing cost of the device and reduces the size of the device. Attached Figure Description
