[Prior art]
Conventionally, coin-type or button-type batteries are small, thin, and lightweight, and thus have been widely used as batteries for small electronic devices. In general, the storage structure for coin-type or button-type batteries in electronic devices is that a coin-type or button-type battery is installed in the battery cover, and the battery cover to which this battery is attached is attached to or detached from a battery holder fixed to a predetermined device. Many battery storage cases that can be freely mounted are used. The peripheral wall of the battery cover is formed so as to be substantially the same height as the upper position of the stored battery in order to stabilize the storage state of the battery.
[0003]
However, after the coin-type or button-type battery is stored in the battery storage case, when the battery needs to be replaced, the battery cover is taken out from the battery holder fixed to a predetermined device, and the battery is taken out from the battery cover. However, since the entire periphery of the battery is covered with the wall surface of the battery cover that is almost the same height as the upper position of the battery, it is difficult to remove the battery even if it is to be taken out. Even if the entire periphery of the battery is not covered, coin-type or button-type batteries are often small, thin, and lightweight, and thus often cannot be taken out using fingers. Accordingly, various battery covers have been provided for facilitating battery removal.
[0004]
For example, in a water purifier that displays the replacement time of a filtration cartridge to a user, it is necessary to use a battery as a power source when driving a liquid crystal panel or a light emitting diode in order to notify the replacement time. With the downsizing, coin-type or button-type batteries have come to be used frequently. For example, in Patent Document 1 below, a notch is provided as a battery cover for a water purifier so that a coin-shaped or button-shaped battery attached inside the water purifier can be removed by hooking a finger (hereinafter, “ "Notched structure") is disclosed. Hereinafter, the battery cover of the water purifier currently disclosed by this patent document 1 is demonstrated using FIG.
[0005]
FIG. 5 is an exploded perspective view of the battery storage case 50 used in the water purifier. The battery storage case 50 includes a battery cover 52 and a battery holder 53 having a notch structure 51, and the battery cover 52 is detachably attached to the battery holder 53 by a bayonet mechanism 54 and an O-ring 55. . When the coin-type or button-type battery 56 is attached, the battery 56 is first attached in the battery cover 52, and then the battery cover 52 is attached to the battery holder 53 by the bayonet mechanism 54 together with the battery 56. Yes.
When it is necessary to replace the coin-type or button-type battery attached to the battery cover 50, the battery cover 52 is first detached from the battery holder 53 by a bayonet mechanism, and then provided on the wall surface of the battery cover 52. The battery is taken out by directly hooking a finger from the recessed portion of the cut-out structure 51 to a part of the outer peripheral side surface of the battery. According to this, even when the entire outer peripheral side surface of the battery is covered with a wall surface that is substantially the same height as the upper position of the battery, it is possible to directly touch a part of the outer peripheral side surface of the battery. Can be easily taken out.
