Abstract

The utility model relates to a dry battery indicating the capacity though self color. The dry battery comprises positive electrode power, a negative electrode zinc can and electrolyte, wherein a thin wall is arranged on the wall of the negative electrode zinc can, the thickness of the thin wall is the same as that of zinc being consumed until the battery is discharged off, PH test paper is pasted to the outer part of the thin wall; the PH test paper is sleeved with a brand sheath of the battery; and a transparent window is reserved in the position of the PH test paper on the brand sheath. When the battery capacity is used up, the thin wall is punched, and the electrolyte is in contact with the PH test paper, so that the changed color of the PH test paper can directly be seen on the brand sheath of the battery. Therefore, the dry battery has the advantages of simple structure and reliability.

Description

Dry cell by self color indication electric weight

Technical field

The utility model is a kind of dry cell.

Background technology

Dry cell in use, chemical reaction constantly takes place in positive and negative pole material, final discharge off fully.Battery has and does not have electricity, can't with the naked eye discern, and electrical equipment is judged by accident easily in use and is fault, causes trouble.Existing dry cell can't be from showing in appearance whether electricity is arranged, and is not directly perceived.

The utility model content

The dry cell of variable color in appearance when the purpose of this utility model is to provide a kind of electric weight to exhaust uses with convenient.

Scheme of the present utility model is: by the dry cell of self color indication electric weight, comprise positive mix, negative pole zinc tube, electrolyte, it is characterized in that: be shaped on thin-walled on the barrel of negative pole zinc tube; the zinc thickness that the thickness of thin-walled consumes when equaling the battery discharge termination; thin-walled is glued with the PH test paper outward; the trade mark crust of battery is enclosed within outside the PH test paper, and the trade mark crust leaves transparent window on the position of PH test paper.

The utility model has the advantages that: the zinc thickness that consumes when equaling the battery discharge termination owing to the walled thickness on the zinc tube, when battery electric quantity exhausts; thin-walled perforation; electrolyte contacts with the PH test paper; the test paper variable color; just can intuitively see on the trade mark crust of battery, has simple in structure, reliable advantage.

Description of drawings

The utility model is described in further detail with embodiment with reference to the accompanying drawings below.

Accompanying drawing is the utility model structural representation.

Among the figure: 1 positive electrode cap, 2 seal, 3PH test paper, 4 thin-walleds, 5 barrier papers, 6 trade mark crusts, 7 carbon-points, 8 positive mixs, 9 zinc tubes.

Embodiment

Referring to accompanying drawing, the battery of embodiment comprises positive mix 8, negative pole zinc tube 9 and the electrolyte of infiltration in positive mix, and structure is identical with existing dry cell.

Be shaped on thin-walled 4 on the barrel of negative pole zinc tube 9, the zinc thickness that the thickness of thin-walled 4 consumes when equaling the battery discharge termination.Because the zinc tube of dry cell all leaves surplus, also has certain thickness when electric weight exhausts, when this battery is made on this basis, the thickness of grinding thin-walled on the zinc tube, the size of thin-walled is ￠ 3mm-￠ 5mm.

The thin-walled 4 outer PH test paper 3 that are glued with.

The trade mark crust 6 of battery is enclosed within outside the PH test paper 3, is seeped into the outside in order to prevent electrolyte, and trade mark crust 6 adopts adhesive sticker, sticks on the zinc tube 9.

Trade mark crust 6 leaves transparent window on the position of PH test paper 3, to observe the color of test paper.

When battery electric quantity exhausts, the thin-walled perforation, electrolyte contacts with the PH test paper, and the test paper variable color just can intuitively be seen on the trade mark crust of battery.

Claims

1. the dry cell by self color indication electric weight, comprise positive mix (8), negative pole zinc tube (9), electrolyte, it is characterized in that: be shaped on thin-walled (4) on the barrel of negative pole zinc tube (9); the zinc thickness that the thickness of thin-walled (4) consumes when equaling the battery discharge termination; the outer PH test paper (3) that is glued with of thin-walled (4); the trade mark crust (6) of battery is enclosed within outside the PH test paper (3), and trade mark crust (6) leaves transparent window on the position of PH test paper (3).
