Abstract

The present invention relates to a target water level alarm device using a laser, and more specifically, a target water level alarm device that is light in weight and does not require separate installation, thus reducing the burden on the user, and measures the water level and notifies the user through an alarm. Regarding this, it consists of a body part that floats on water, a battery, a button to set the target water level, and a speaker that notifies the user through an alarm, preventing the user from concentrating on other tasks or working at all while filling the water to the target level. It has the effect of enabling efficient use of time by resolving problems that cannot be progressed.

Description

Target water level alarm device using a laser {TARGET WATER LEVEL ALARM DEVICE USING LASER}

The present invention relates to a water level alarm device, and more specifically, to a water level alarm device that measures the water level through irradiation and reception of a laser beam and notifies the user that the target water level has been reached.

When filling something like a bathtub with water, it is very difficult to know exactly how long it will take to reach the water level I want to target. This is because the water discharge capacity per hour and the allowable capacity of the bathtub are different for each household. In particular, when there are young children at home, there is a high risk of accidents occurring in the blink of an eye, so if you have to pay extra attention, you often cannot use your time efficiently because you cannot concentrate on other things. The present invention seeks to solve the above problems using laser irradiation and reflection. The above problem can be solved by measuring the current water level in real time using a laser and notifying the user through sound when the preset target water level is reached, allowing the user to utilize time efficiently.

U.S. Patent Registration No. 80-65759 (“McClain's bathtub monitor”, published date: October 2, 2008) Republic of Korea Patent Publication No. 1597279 (“Bathtub water level alarm”, publication date: 2016. 03. 02) Republic of Korea Patent Publication No. 2026339 (“Buoy type laser water level gauge, publication date: 2019.10.02)

The present invention solves the problem of not being able to accurately determine the time it takes to reach the desired water level when filling a place such as a bathtub, and due to this, the inability to use time efficiently, such as not being able to concentrate on other tasks by checking the water level from time to time. We want to solve the problem.

According to an embodiment of the target water level alarm device using a laser according to the present invention for achieving the above object, a laser irradiation unit and a receiver for measuring the water level, a battery and charging terminal, a display unit for displaying the current water level, and a button for setting the target water level ; It is composed of a body part that floats on water, including the irradiation unit and the receiver, and the irradiation unit and the receiver are characterized by using a laser that can penetrate water to minimize errors in irradiation and reception of the laser. The body is made of hydrophobic material and is waterproof and has the property of floating on water. The display unit, target water level setting button, and speaker are located at the top, so the target water level can be set and the current water level can be checked visually. The target water level can be confirmed through the speaker. It is characterized by notifying the user that has been reached.

The target water level alarm device using a laser of the present invention notifies the user through an alarm when the target water level is reached without the inconvenient process of requiring a person to check the water level directly from time to time, allowing the user to focus on other tasks in the meantime. is measured in real time using a laser beam and appears on a screen displaying the water level, allowing the user to directly check the current water level. The water level measurement line of the laser beam visually disappears when the target water level is reached, so it has no effect on water use.

Since it does not require separate installation, there are no installation costs and it has the advantage of being economical as it can be used in various places, including all bathtubs.

As shown in Figures 1 to 3, the target water level alarm device according to an embodiment of the present invention includes a laser irradiation unit and a receiver 102 for measuring the water level on the floating body 100, and a battery 200. And it includes a charging terminal 210, a display unit 110 that displays the current water level, a button 120 that sets the target water level, and a speaker 130.

Set the target water level by placing the water level alarm device at the desired water level and pressing the button 120 to set the target water level. Afterwards, when the water level rises, the water level is measured in real time through the laser irradiation unit and receiver 102, and the current water level is displayed on the display unit 110. Afterwards, when the target water level is reached, an alarm sound is sounded through the speaker 130 to notify the user.
