The present invention relates to a safety cup melody sound output device and method for the visually impaired, and in particular, when a certain amount of water or drink fills the container, the alarm sounds sequentially so that the visually impaired can check the deduction of water through the warning sound. It relates to a safety cup melody sound output device and method for the visually impaired.

In general, it is well known that a cup for drinking along with water or a drink depends on the size of the content to be filled according to the size, so that the user should drink according to the amount of the desired content.

However, the visually impaired can not follow the desired amount at a time because it can not be identified by the eye, there is an inconvenience to drink a few times a little, there is a problem that if you are not careful with a little water flows can be burned in case of hot water.

This phenomenon is more frustrating for people who are visually impaired due to accidents, etc., and it is more convenient to feel frustrated if they can feel as if they can see it without looking at the sound instead of seeing it. You will feel.

That is, when you want to drink water or drink in the container, there is a hassle to check how much the container is filled while touching or judging by the sound of the container.

Meanwhile, in order to solve such a problem, a melody cup was previously filed, and Utility Model Application No. 1986-0002590 provided a melody flowing out according to the operation of the switch to enhance the auditory inspiration.

In addition, Utility Model Application No. 2001-0007103 informs the visually impaired with the volume of the contents of the container, so that the disabled can drink beverages without spilling on the floor.

However, since the prior application technology adopts a structure in which the melody is output when the beverage is filled in the container, the melody is output even when the container is filled with water.

In other words, although the visually impaired melody sound is output only when the drink is eaten and the melody is not output when the drink is filled in other situations, there are many inconveniences due to continuous melody sound output.

The present invention is to solve the above problems,

It is a first object of the visually impaired person to maximize the use of the melody sound output container by outputting the melody sound only when the beverage is poured into the container to eat the drink.

In addition, the second purpose of the melody sound output device to be displayed to the outside when the failure so that it is easy to recognize whether the failure.

In addition, the third purpose is to display the operating state through the indicator lamp to be used as a play equipment.

As a means for achieving the object of the present invention,

The present invention includes a cup including a container having a circular or polygonal shape, and a handle installed on one side of the container; An operation switch installed at one side of the handle of the cup and contacted by a pressing operation to output an electrical signal; A water level sensor installed inside the container of the cup and contacted when the liquid is in contact with the liquid level sensor to output an electrical signal; A microcomputer for controlling the melody sound to be output only when the operation switch and the water level sensor are contacted at the same time; A melody sound output device for outputting a melody sound under the control of the microcomputer; It is mounted to the lower portion of the container, characterized in that it comprises a battery for supplying electricity to the operation switch and the water level sensor and the microcomputer and melody sound output device.

In addition, it is installed on the outside of the container, characterized in that made by further installing a failure display lamp for outputting a failure signal by checking the current flow of the melody sound output device.

In addition, the outer side of the container is characterized in that the indicator is further provided to turn on the lamp only when the operation switch and the water level sensor is in contact with the electrical signal from the microcomputer.

In addition, receiving a contact signal from the operation switch; Receiving a contact signal from a water level sensor; Outputting a melody sound output signal when it is confirmed that the contact signal is simultaneously input from the operation switch and the water level sensor; It checks the current flowing from the battery to the melody sound output device, and if the current does not flow is characterized in that the step of outputting a signal to the fault indicator lamp.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

The present invention is largely the operation switch 10, the water level sensor 20, the microcomputer 30, the battery 40, the melody sound output unit 50, the current sensor 60, the indicator lamp 70 and a failure display lamp 80. Reference numeral 90 is a relay medium for recording the melody sound and the operation mode in the microcomputer 30 as a communication port.

The respective devices are all electrically connected, and in particular, the current feedback line 60 is connected between the battery 40 and the melody sound output unit 50 to signal the melody sound output unit 50 from the microcomputer 30. When the power is not applied even when the power supply is applied, it is determined that the abnormality occurs in the melody sound output unit 50, and the microcomputer 30 is configured to turn on the failure display lamp 80.

First, the cup 100 of the present invention consists of a container 110 of a circular or other polygonal shape, and a handle 120 attached to the side of the container 110, a plurality of water level inside the container 110 The sensor 20 is mounted, the operation switch 10 is installed at one side of the handle 120, and the battery 40 and the microcomputer 30 for controlling the operation are installed at the lower side.

Of course, since the battery 40 and the microcomputer 30 are sealed by the case, the handle 120 is installed in the container 110 from the outside, and the operation switch 10 can be recognized to provide a neat appearance. .

The present invention connects the microcomputer 30 to the operation switch 10 and the water level sensor 20, and the melody sound stored in the microcomputer 30 is externally only when the water level sensor 20 and the operation switch 10 are simultaneously contacted. It was configured to output.

That is, simply pressing the operation switch 10, or if only the water level sensor 20 is configured to be inoperative so that the visually impaired hand while holding the handle of the cup 100, the operation switch 10 is naturally in contact, In addition, when the water level sensor 20 contacts with water in the container 110, the microcomputer 30 recognizes this and outputs a melody sound.

The water level sensor 20 is installed a plurality of bar, preferably at least three, it is preferable, when the water level sensor 20 of the lowest point is relatively low melody sound is output, the high melody sound every time to go to the highest point The output of the water can be perceived by the visually impaired by hearing.

As a result, the visually impaired person can hear the sound of converting the melody sound or the high pitched sound and recognize how much water is filled in the container.

In particular, when hot water is filled in a container, the water overflows in the past, but there is a case of an accident, but by using the present invention, it is possible to recognize the deduction of water as a voice, thereby preventing a safety accident in advance.

In addition, in the present invention, since the melody sound is output only when both the operation switch 10 and the water level sensor 20 are in contact with each other, the melody sound is not output to the outside when the operation switch 10 is not contacted when washing dishes. It can be washed easily.

That is, since the conventional cup 100 having a melody sound output function is simply mounted only the water level sensor 20, the melody sound is continuously output to the outside even when the water is filled to wash the cup 100, which is very inconvenient.

However, in the present invention, since the melody sound is output to the outside only when both the operation switch 10 and the water level sensor 20 are contacted by dividing the switch into two, the melody sound is output to the outside except for the filling of water. You can prevent it.

In addition, the present invention can also be used as a play device for children, for this purpose, a plurality of display indicator lamps 70 are installed for this purpose, and the melody sound is output and the indicator lamp 70 is turned on according to the water level. Can be.

Of course, since the indicator lamp 70 also operates only when both the operation switch 10 and the water level sensor 20 are in contact with each other, an operation of simply pouring water or other liquid into the container as an action for washing the cup 100. By itself, the indicator lamp 70 does not work.

In addition, it is possible to check whether there is an abnormal operation by outputting it through the display lamp whether the device can be used normally from the outside, thereby increasing the convenience of use.

In addition, since the current detection sensor unit 60 is installed at one end of the melody sound output device, when the battery power is not properly applied to the melody sound output device, the failure display lamp 80 is turned on so that the external device can recognize it.

As a result, the present invention allows the melody sound to be output only when both the operation switch 10 and the water level sensor 20 are operated or the indicator lamp 70 is turned on to operate only when the user uses the water for drinking. This can minimize battery consumption due to unnecessary operation.

5 is an operational flowchart of the present invention.
