Abstract

PURPOSE:To make it possible to check remaining capacity by visually observing, from outside, change of material generated by discharge. CONSTITUTION:An external circumferential observation window 11 makes it possible to check charge of surface of a zinc plate 4 by discharge through an external circumferential insulating material 5. Change of discharge can be checked easily by making it easy the identification of color by coating the external surface of zinc plate 4 with the material which enlarges surface change by discharge. The upper surface observing window 12 provided in the positive side makes possible change of color through a support ring 7, an external circumferential insulating material 5, an anode cover 8 and a packing 9 by changing color of display plate 13 through inductive transmission of change of chemical material 2 in the dry battery to the display plate 13 with a lead wire 14.

Description

[Detailed Description of the Invention] This invention is based on the appearance that U (++ aid or i + J) can be used with one finger.
and C.

Conventionally, in order to monitor mobile phones, dry cell batteries have been used with voltage measuring meters to check for changes in the material that makes up the dry cell or the material that is completely sealed to prevent leakage to the outside. You can check the remaining capacity of the battery by connecting the terminals to the anode and cathode and pointing the meter to 1, or by turning on the light bulb, or by touching the terminals to your tongue and checking the degree of stimulation you feel. The reality is that we are checking to see if it exists.

In this invention, an observation window is provided on either the anode side, the cathode side, or the side of the dry turtle pond, so that it is possible to check the indication by color change.

To explain the embodiments of the f7H) composition of this invention shown in the drawings, (1) is a carbon body, (2) is a chemical material, (3) is cardboard, (4) 1 is a lead plate, (5) is outer insulation material, (6) is inner insulation material, (7) is support ring, (8) is anode cover, (9
) is the backing, and (lO) is the outer case, which are the parts of a commercially available dry battery. (1υ is a side observation window, and a window is drilled in a part of the outer case (10) and the transparent outer insulating material (5
) to enable observation of surface chemical changes on the zinc plate (1). On the surface of the M lead plate (4), there is an enlarged indication of chemical changes.
J-functional materials may be applied. Further, this observation window may be provided on the cathode side F blood.

α-Gun is a top observation window that is drilled in a part of the banking (9) or 1-field electrode cover (8) to see through the outer insulation material (5), support ring (7), and anode cover (8). Then, observe the instruction board 04 in a town performance. a: An indicator board is made of a material that indicates the chemical change of the chemical material (2), and is attached to the F side of the support ring (7) or the anode cover (8). 04) is a conductive wire made of a material that can transmit chemical changes in the chemical material (2), and one end is inserted into the fL element wire (2) and the inner insulation wire (6) is connected to 1"
Insert it through one end and connect the other end to the indicator board (13j).

Since the above η11 is configured, the anode 1 of the dry battery

Through the observation window at t, it is possible to observe color changes caused by the dry discharge of the pond.

The observation window may be a combination of a plurality of windows, or may be a combination of ii'1-several numbers. The outer observation window (11) is: llj

The change fL can be seen through the peripheral insulation gain (5).

A two-sided observation window (12) installed on the anode side indicates the change in the chemical material (2) inside the dry pond through the indicator board A1.
The color of the indicator board (13) is changed by guiding and transmitting the information to the support ring (7), the outer insulation material (5), the anode cover (8), and the backing (9) to confirm the chromaticity.

In this invention, changes in the constituent materials of the dry cell battery were explained using color markings, but a sticker made of a material that changes color during storage and discharge is pasted on the outside of the dry cell battery.
; +t +d, and the discharge may be sensed to check the remaining voltage of the dry cell.

As explained above, by observing the color change in the observation window provided on the outside of the dry battery, the remaining power IJt can be reduced to N1 in a short time. There is no need to carry a voltage measuring meter, no need to connect a light bulb to check for burning, and no need to touch the poles to the tongue to check for stimulation. Also, even women and P1 children who do not know how to check the residual capacity meter can issue an edict for the residual capacity at the ν1'' position.

Claims (1)

[Claims] This invention relates to an indicating device 6 that makes it possible to barely recognize from the appearance whether the discharge of a dry battery is complete or not. Inui's discharge completion indicator fR is characterized by displaying the change in the element H generated by discharge so that it can be confirmed from the outside with one finger.
