Description

Anti-overflow cup for the blind

technical field

The invention relates to an anti-overflow cup for the blind, which belongs to the technical field of daily household items.

Background technique

The blind are a group that needs care. With the development of society, there are more and more designs for the blind to solve their life obstacles. Water is vital to the human body, but due to visual impairment, it is very inconvenient for the blind to pour and drink water, especially when pouring water, because they cannot see the rise of the water level, they can only rely on their senses, sometimes they feel wrong or have inattention Concentrate and the water will overflow from the cup. This has not only caused the waste of water resources but also affected the cleanliness of the surrounding environment, and brought certain psychological pressure to the blind. If the water with a higher temperature overflows, it will cause burns.

In order to solve this problem, some similar patents existing on the market now. For example, "Patent No.: 2012201898371 Utility Model Name: Water Cup for the Blind" uses sensors and alarms to prompt the water level, but the utility model is relatively expensive, and electronic products not only increase the psychological burden of the blind, but also bring charging troubles, which discourages many blind people. For example, "Patent No.: 2013103268101 Name of Invention: Water Cup for the Blind" utilizes one end of the connecting rod to touch the water surface to float, and the other end drops to touch the finger of the blind person to prompt the change of the water level of the blind person. However, the volume of the connecting rod in contact with the water is too small, which may easily cause problems of insufficient buoyancy and low sensitivity to water level changes. At the same time, after the connecting rod is impacted by the force of the water flow vortex in the cup, the connecting rod will be subjected to the lateral or lateral resistance of the fulcrum when it rotates around the fulcrum, which will affect the stability of the floating direction of the connecting rod and its response to the change of water level. Sensitivity, the direct exposure of the connecting rod to touch the fingers lacks attention to the self-esteem of the blind. At the same time, the distance between the connecting rod touching the water and the cup mouth is too close, which does not allow enough reaction time for the blind. For example, "Patent No.: 2014107880089 Invention Name: Water Cup for the Blind". It raises the other end of the connecting rod structure and turns it downwards to make a sound reminder. The sound will bring a psychological burden to the user and cannot provide enough reaction time. , still presents a risk of burns.

The working principle of this specific embodiment is: when the blind person pours water, the index finger of the blind person touches the positions 2-3 of the rectangular braille hole when holding the cup. The foam float 3-1 rises along with the rise of the water level, and the end of the buoy connecting rod 3-2 near the foam float 3-1 rises thereupon, and the other end will use the rotating hole 3-3 as the lever fulcrum to generate a downward force. Arc motion. Now, I-shaped latch 4-2 is subjected to the traction of buoy connecting rod 3-2 descending end and descends thereupon. Due to the existence of the rounded rectangular sliding hole 3-4, the I-shaped latch 4-2 can slide in the rounded rectangular sliding hole 3-4 on the basis of ensuring that the horizontal distance from the rotating hole 3-3 is basically unchanged, thereby producing The relative position of the rounded rectangular sliding hole 3-4 changes. At this time, the I-shaped latch 4-2 moves downward in an almost vertical direction, and then drives the U-shaped connecting rod main body 4-1 in the vertical direction. Move Downward. The braille column 4-4 will move down thereupon, passing through the rectangular braille hole 2-3 on the turning surface 2-2 at the bottom of the outer mask layer 2, giving the hand of the blind a sense of touch, and prompting the water level of the blind with the Braille "full" character full. After the foam float 3-1 floats and triggers the Braille post 4-4, since the water surface is still a certain distance away from the mouth of the cup, enough reaction time is reserved for the blind, which solves the problem that the blind is prone to overflowing and scalding when pouring water.
