Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent bathroom, and in particular to an intelligent aging bathroom device based on human posture recognition. BACKGROUND

[0002] The bathroom space occupies an important position in the family residence and is relatively private, and the bathroom space is usually used independently by a single person. The decline of the body function of the elderly leads to the decline of the action ability and the sensory ability, and when a single person uses the ordinary bathroom space, the single person is in a small and special closed space, and it is difficult to find and rescue in time when an accident occurs, causing a safety risk.

[0003] In order to meet the independent self-care and personal privacy needs of the elderly in their later years, the bathroom space needs to be modified for the elderly, so as to meet the independent use of the elderly. However, the existing aging modification usually only simply sets handrails on the walls of the shower and the toilet for the elderly to use for support, so as to avoid the elderly from falling, or sets an infrared human body sensor in the bathroom space to monitor whether the elderly fall.

[0004] The existing aging modification in the bathroom space fails to realize the functional integration between different bathroom products, but only simply increases some equipment, which makes it more inconvenient to move in the small bathroom space, and instead causes inconvenience and an increase in safety risks.

[0024] The lifting seat 221 is provided with a storage battery, and the lifting millimeter wave radar 4 is connected with the storage battery through wires. The lifting millimeter wave radar 4 is powered by the storage battery in the lifting seat 221, which avoids wiring and improves the flexibility of lifting.

[0025] Working principle: when the bathroom space is adapted for the old, the functions of the closestool 1 and the shower device 2 are integrated, the closestool 1 can be used as a “sitting tool” for the old when using the shower device 2, so as to avoid the old standing for a long time when bathing, the shower device 2 and the closestool 1 are integrated, the idle area of the bathroom space is increased, the convenience of movement is improved, and the old can be accompanied and assisted by others in special circumstances. Through the setting of the posture detection module, the bathroom product is intelligently transformed, the fixed millimeter wave radar 3 is used to identify the posture change of the human body and detect the falling action, and the height of the shoulder of the human body detected by the lifting millimeter wave radar 4 is used to control the lifting seat 221 of the driving mechanism 22 to move up and down along the vertical direction, so that the height of the shower nozzle 24 is within the set range from the height of the shoulder of the human body, so that the old can keep the shower nozzle 24 within the range that can be contacted by the hands regardless of sitting or standing when bathing, on the one hand, the water pressure is weakened and the water temperature is unstable due to the too far distance between the shower nozzle 24 and the human body, and on the other hand, the old can easily rotate and adjust the cleaning direction of the shower nozzle 24, thereby improving the convenience of bathing.

[0026] The bathroom fixed millimeter wave radar 3 is powered and signals are transmitted through the cable in the wall, so it can be kept in an enabled state for a long time, while the lifting millimeter wave radar 4 is powered by a battery in the lifting seat 221, and the endurance time is short, so it is only enabled after the switch seat 21 opens the shower head 24, and the controller controls the lifting seat 221 to rise or fall by a fixed distance based on the body posture change detected by the fixed millimeter wave radar 3 when the lifting millimeter wave radar 4 fails, such as standing, the lifting seat 221 rises to the set highest point, and the body posture is sitting, the lifting seat 221 falls to the set lowest point, realizing centimeter-level cooperative tracking of the double radars, and avoiding single millimeter wave radar failure. Embodiment 2

[0027] The first handrails 11 are arranged symmetrically on both sides of the closestool 1, the first handrails 11 are in a "U" shape, and the end portions of the first handrails 11 are fixedly installed on the bathroom wall, so as to support the elderly to stand off the closestool 1 and perform standing shower.

[0028] Further, the first rubber sleeve 111 is arranged on the first handrail 11, and a plurality of first convexes are arranged in an array on the first rubber sleeve 111, so as to improve the anti-slip ability of the surface of the first handrail 11. Embodiment 3

[0029] The second handrails 12 are arranged in parallel on the bathroom wall, and the water supply hose 25 is connected to the water supply metal pipe 23 after passing through the gap between the second handrails 12 and the bathroom wall.

[0030] The second handrails 12 not only facilitate the elderly to stand, but also limit the position of the water supply hose 25, so as to avoid that the water supply hose 25 that is too long to adapt to the lifting of the shower affects the elderly to take a shower.

[0031] Similarly, the second rubber sleeve is arranged on the second handrail 12, and a plurality of second convexes are arranged in an array on the second rubber sleeve, so as to improve the anti-slip ability of the surface of the second handrail 12. Embodiment 4
