The present invention relates to a moisture inflow level checker, and more specifically, to a moisture inflow level checker that is attached to various devices and can easily check with the naked eye whether and to what extent moisture is flowing into the device.

In modern society, as the demand for semiconductors, electrical and electronic products, or electronic devices, increases rapidly by incorporating office automation, artificial intelligence, and AI technology, damage to products that have been used in a few minutes may also increase rapidly.

Electronic devices may refer to portable communication devices, liquid crystal displays, computers, portable electronic calculators, and battery packs. In general, a separate moisture inflow sensor can be applied to electronic devices that can measure information such as whether moisture is inflow and time of inflow. However, since the moisture inflow sensor must be separately provided and printed separately on a printed circuit board on which the electronic circuit is implemented, unnecessary manufacturing costs may be incurred, and it is difficult for users to intuitively recognize the moisture inflow time.

In addition, there are cases where flooded vehicles are sold as normal vehicles, so an indicator is needed to indicate whether the vehicle has been flooded.

The purpose of the present invention is to provide a device that can be attached or stored in various devices to inform whether moisture is or has been introduced into the device, to easily check the degree of inflow with the naked eye, and to leave an indicator of the inflow to confirm the reliability of the transaction. It provides a moisture inflow level checker.

The moisture inflow level checker according to the present invention includes first and second transparent films coated with waterproofing; a moisture inflow member exposed to one side of the first and second transparent films and allowing moisture to flow in; and a moisture absorbing member disposed between the first and second transparent films and discolored when receiving moisture flowing into the moisture inlet member.

The first and second transparent films may be bonded to each other and sealed to prevent moisture from entering except for the moisture inflow member portion.

The moisture absorbing member may be provided with an indicator on one surface indicating the time at which the moisture was introduced, based on the moisture absorption ability.

It may further include an adhesive member formed on one of the first and second transparent films to attach it to an arbitrary electronic device, and the adhesive member may be provided with an authenticity mark through which the authenticity of the mark can be determined.

It may further include a moisture expansion member that is in contact with the moisture absorption member and expands when absorbing the moisture.

The moisture expansion member includes: a housing having a space inside, one side of which is open, and irreversible damage occurring due to external force; and an expansion agent that is disposed in the inner space of the housing and expands when it absorbs moisture.

The moisture expansion member may be arranged so that one open surface is in contact with the top or side surface of the moisture absorption member.

The housing may further include an opening frame disposed on one surface of the opening.

The moisture absorbing member is made of a different material from the moisture inlet member, and the width of the moisture absorbing member may be 1 medium and 1.5 times the width of the moisture inlet member.

A sensor that outputs a detection signal when moisture enters the moisture inflow member; And it may further include a processor that stores the inflow time of the moisture when the detection signal is input.

The moisture inflow level checker according to the present invention allows the user to easily determine the degree and time of moisture inflow into the device with the naked eye, and can reduce manufacturing costs.

It may consist of, but is not limited to this.

The thickness of the first and second transparent films 110 and 120 may be 0.1 mm to 1 mm. If it is less than 0.1 mm, water may flow in, and if it is thicker than 1 mm, the effect on water inflow will not increase and the manufacturing Costs may increase.

The first and second transparent films 110 and 120 are preferably made of an elastic material. This is because the moisture absorbing member 140 is disposed between the first and second transparent films 110 and 120.

Facing surfaces of the first and second transparent films 110 and 120 may be bonded to each other, and the sides may be sealed to prevent moisture from entering. The surfaces of the first and second transparent films 110 and 120 that face each other may be adhesive surfaces, or adhesive may be applied to the surfaces that face each other.

At least a portion of the moisture inflow member 130 may be disposed between the first and second transparent films 110 and 120 and exposed to one side of the first and second transparent films 110 and 120. Through the moisture inflow member 130, moisture may flow between the first and second transparent films 110 and 120 bonded together. That is, the moisture inflow member 130 may function as an inlet through which moisture flows between the first and second transparent films 110 and 120.

The moisture inflow member 130 may be divided into first and second regions.

The first area of the moisture inflow member 130 may be a portion exposed to one side of the first and second transparent films 110 and 120. The second region of the moisture inflow member 130 may be disposed between the first and second transparent films 110 and 120, that is, a portion that overlaps the first and second transparent films 110 and 120. The moisture inflow member 130 may extend from the first area and be connected to the moisture absorption member 140.

In the embodiment, the moisture inflow member 130 is shown as being divided into the first and second regions based on one side of the first and second transparent films 110 and 120, but the present invention is not limited thereto.

The moisture inflow member 130 may be an extension of the moisture absorption member 140 or may be made of the same material, but is not limited thereto, and may be formed of a material different from the moisture absorption member 140 and connected to the moisture absorption member 140. You can.

That is, between the first and second transparent films 110 and 120, there is no space for air or moisture other than the moisture absorbing member 140 (excluding some moisture inflow members 130). The transparent films 110 and 120 and the moisture absorbing member 140 are preferably sealed.

The moisture absorbing member 140 may be fixedly arranged in a zigzag shape on at least one of the first and second transparent films 110 and 120. Rather than being limited to a zigzag shape, the moisture absorbing member 140 may be cut into a shape having a long path on opposing surfaces of the first and second transparent films 110 and 120.

The moisture absorption member 140 may absorb moisture introduced through the moisture inflow member 130. If moisture touches the moisture absorbing member 140, the moisture absorbing member 140 may be discolored. It is desirable that the discolored color is a color compared to the color before moisture absorption so that moisture absorption can be visually confirmed.

An existing submerged label or a modified version thereof may be used as the moisture absorbing member 140. The moisture absorbing member 140 may be structured such that when moisture flows into a porous film disposed on solid ink, like a conventional submersible label, the ink melts and wets the surrounding paper, changing its color.

Existing submerged labels have a malfunction in which the label color changes when a sudden temperature change occurs, but the moisture absorbing member 140 according to this embodiment is sealed on the top, bottom, left, and right sides, so a malfunction may not occur even with a sudden temperature change. Additionally, since the moisture absorbing member 140 is sealed, the discolored color may not easily disappear.

The moisture absorbing member 140 may have the same width as the moisture inflow member 130 or may have a different width. The width of the moisture absorption member 140 may be 1 to 1.5 times the width of the moisture inflow member 130. If it is less than 1 times the width of the moisture inflow member 130, absorption is faster compared to the inflow of moisture, but the length may be long. If it is larger than 1.5 times, the inflow of moisture may not be uniform.

The moisture absorbing member 140 may be provided with an indicator indicating the inflow time of moisture. For example, based on the moisture absorbing power of the moisture absorbing member 140, an indicator representing the movement time of moisture according to the moving distance of the moisture absorbing member 140 may be expressed as a number for each distance. In other words, through the number of discolored parts, the user can know how long moisture has been flowing into the moisture inflow level checker.

In the embodiment, the moisture absorbing member 140 is shown and described as being indicated by the above numbers, but in addition to the numbers, a scale that can be checked with the naked eye may be displayed, and is not limited thereto.

In order to attach the moisture inflow level checker 100 to any electronic device, an adhesive member 150 may be formed on any one of the first and second transparent films 110 and 120.

The adhesive member 150 may be provided with an authenticity mark through which the authenticity of the mark can be determined. It is desirable that the authenticity mark is a mark that is difficult to forge or falsify, such as a hologram or biometric authentication mark. The authenticity mark can indicate the manufacturer of the product to which it is attached, the date of manufacture, etc., and the date of creation of the authenticity mark. The authenticity of an authenticity mark can be determined through a public or certified agency.

For example, if a car leaves the factory with a water ingress level checker equipped with this authenticity mark, and the car does not have this water ingress level checker or the authenticity mark is forged, the vehicle is treated as a flooded vehicle. can do.

The adhesive member 150 may be an adhesive or a film coated with an adhesive. The authenticity mark may be placed between the adhesive member 150 and the second transparent film 120, or may be placed inside the adhesive member 150.
