Abstract

The utility model relates to the technical field of calculators, in particular to a portable calculator which comprises a shell. The shell is provided with a display screen, keypads and a solar power supply module used for conducting auxiliary power supply for a main battery which is arranged in the shell; and as the solar power supply module and the main battery conduct dual-power supply, the portable calculator can prolong the service life of the main battery, avoid the troublesome of changing the main battery frequently, reduce the discarded quantity of waste batteries, and achieve the purpose of energy conservation and environmental protection.

Description

Hand-held calculator

Technical field:

The utility model relates to the counter technical field, relates in particular to a kind of hand-held calculator.

Background technology:

In daily life work, counter is used by people widely as basic office tools.Particularly aspect financial, calculate owing to often need carry out a large amount of accounts, so counter is one of the office appliance of staff such as accounting, cashier indispensability especially, and hand-held calculator, because it is easy to carry, very popular especially.

Existing hand-held calculator, it mainly comprises housing, is provided with the lithium battery that is used to power in the housing, still, this hand-held calculator only adopts single lithium battery power supply usually, when counter uses when frequent, lithium battery is easy to use up electricity, causes the electricity shortage of counter, need often to change lithium battery, especially be sealed in lithium battery in the housing for some and do not allow easily detachable counter, some user may will abandon counter, causes the waste of resource.

The utility model content:

The purpose of this utility model is to provide a kind of hand-held calculator at the deficiencies in the prior art, and it adopts solar powered module and main battery to carry out dual power supply, thereby prolongs the serviceable life of main battery.

The purpose of this utility model realizes by following technical measures:

A kind of hand-held calculator, it includes housing, and housing is provided with display screen, button, is provided with main battery in the housing, also is provided with on the described housing to be used to main battery to carry out the solar powered module of auxiliary power supply.

Described main battery is a lithium battery.

Described button is arranged.

Also be provided with rubber blanket in the described housing with the button coupling.

Also be provided with control circuit board in the described housing.

The back side of described housing is provided with the battery cover that is used for the cover cap main battery.

Described battery cover offers screw.

Described housing comprises loam cake, lower cover, and loam cake and lower cover fasten mutually.

Described display screen is LCDs (LCD).

The utility model beneficial effect is:

The utility model includes housing, and housing is provided with display screen, button, is provided with main battery in the housing, also is provided with on the housing to be used to main battery to carry out the solar powered module of auxiliary power supply; Owing to adopted solar powered module and main battery to carry out dual power supply, therefore, the utility model can prolong the serviceable life of main battery, avoids often changing the trouble of main battery, also can reduce the quantity that abandons of refuse battery, reaches the purpose of energy-conserving and environment-protective.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described, shown in Fig. 1～3, a kind of hand-held calculator that the utility model provides includes housing 1, housing 1 is provided with display screen 2, button 3, be provided with main battery 4 in the housing 1, main battery 4 is a lithium battery, it is responsible for the main power supply of counter, also be provided with on the housing 1 and be used to main battery 4 to carry out the solar powered module 5 of auxiliary power supply, when counter full load full speed operation, solar powered module 5 can be carried out auxiliary power supply for main battery 4, thereby prolongs the serviceable life of main battery 4.

The button 3 of present embodiment is arranged, to form compact arrangement, reduces the volume that button 3 takies counter; Also be provided with the rubber blanket 6 that mates with button 3 in the housing 1, rubber blanket 6 unclamps finger after button 3 is pressed between button 3 and control circuit board 7, and rubber blanket 6 has recovery elastic force, and button 3 is upspring; Wherein, button 3 according to the different mining of function with different colors, so that User Recognition is accelerated input speed.

Also be provided with control circuit board 7 in the housing 1 of present embodiment, control circuit board 7 is provided with low consumption circuit, this low consumption circuit is when satisfying computing velocity, can enable the green power consumption mode of power saving, under this pattern, current sinking only is several microamperes, has further prolonged the serviceable life of main battery 4.

The back side of present embodiment housing 1 is provided with the battery cover 8 that is used for cover cap main battery 4, and battery cover 8 offers screw 81, so that by screw battery cover 8 is fixed on the housing 1.

The housing 1 of present embodiment comprises loam cake 11, lower cover 12, and promptly housing 1 is made up of loam cake 11 and lower cover 12, and loam cake 11 fastens mutually with lower cover 12; Display screen 2 is a LCDs, and it has good display.

The utility model in use, owing to adopted solar powered module 5 and main battery 4 to carry out dual power supply,, avoided often changing the trouble of main battery 4 so prolonged the serviceable life of main battery 4, also can reduce the quantity that abandons of refuse battery, reach the purpose of energy-conserving and environment-protective; And, just can change main battery 4 easily by dismounting cell lid 8, avoid counter to abandon, cause the waste of resource.

Should be noted that at last; above embodiment is only in order to the explanation the technical solution of the utility model; but not to the restriction of the utility model protection domain; although the utility model has been done to explain with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the essence and the scope of technical solutions of the utility model.
