Device.
Due to refrigerator thermometer be all using battery powered, can not circumscripted power line.Existing refrigerator thermometer is all
It is constantly in open state, the moment carries out temperature monitoring, therefore power consumption is very fast, and service life is shorter, usual consumer's replacement
Battery is also more troublesome.
Summary of the invention
In order to overcome the above-mentioned deficiency of the prior art, the utility model provides a kind of little power consumption and service life long refrigerator temperature
Meter.
The technical scheme in the invention for solving the technical problem is: a kind of refrigerator thermometer, including lighttight shell,
The front end of the shell is equipped with the cover board of light transmission, is equipped with circuit board in the shell, the rear end face of the circuit board with it is described
The inner wall of shell abuts to form dark surrounds, and the rear end of the circuit board is equipped with light-operated switch, which is in described
Dark surrounds in, the front end of the circuit board is equipped with the display screen of the information by displays temperature based on, the display screen with it is described
Circuit board electrical connection is also provided with loophole on the circuit board, injects so that extraneous light may pass through the loophole
Into dark surrounds.
It further, further include a hanger, the shell is equipped with turn hole, and the hanger is equipped with shaft, and described turns
Axis is inserted into the turn hole.
Further, the shell is equipped with flange, and the turn hole is located in the flange, the lower end of the hanger
Be additionally provided with supporting block, the supporting block can be abutted with the flange, the upper end of the hanger with can be with the support in refrigerator
Face abuts.
Further, the loophole is located at the edge of the circuit board, and the edge of the cover board is equipped with coating.
Further, the circuit board is equipped with reset switch, and the shell is equipped with opposite with the reset switch
The reset button of position.
The utility model has the beneficial effects that: passing through the cooperation of light-operated switch and loophole, so that refrigerator thermometer can
To follow ambient light variation automatic conversion shutdown or booting.When refrigerator doors are closed, light-operated switch does not receive light, thus
Refrigerator thermometer automatic shutdown；When refrigerator doors are opened, light is injected into dark surrounds from loophole, and light-operated switch receives
Light opens refrigerator thermometer.Therefore, more power saving environmental protection when use, the service life is longer.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
The front end of referring to Fig.1~Fig. 6, a kind of refrigerator thermometer, including lighttight shell 1, the shell 1 is equipped with light transmission
Cover board 2, circuit board 3 is equipped in the shell 1, the rear end face of the circuit board 3 abuts to be formed with the inner wall of the shell 1
The rear end of dark surrounds 15, the circuit board 3 is equipped with light-operated switch 4, which is in the dark surrounds 15
In, the front end of the circuit board 3 is equipped with the display screen 5 of the information based on displays temperature, the display screen 5 and the circuit board 3
Electrical connection is also provided with loophole 6 on the circuit board 3, thus extraneous light may pass through the loophole 6 be incident upon it is black
In dark situation 15.
In the present embodiment, the display screen 5 can all multi informations such as displays temperature information, information about power, security information,
With guarantee the refrigerator thermometer normal table use.Preferably, it is also integrated with auto-alarm function on the refrigerator thermometer,
When temperature is more than 0 °C ~ 8 °C/32 °F ~ 46.4 °F this safety zone ranges, meeting automatic alarm, to remind user
Check the abnormal condition of refrigerator and refrigerator thermometer.
It further include a hanger 7 in the present embodiment, the shell 1 is equipped with turn hole 8, and the hanger 7 is equipped with shaft 9,
The shaft 9 is inserted into the turn hole 8.The shell 1 is equipped with flange 10, and the turn hole 8 is located at described
In flange 10, the lower end of the hanger 7 is additionally provided with supporting block 11, and the supporting block 11 can be abutted with the flange 10, institute
State the upper end of hanger 7 with can be abutted with the supporting surface in refrigerator.Using the structure of the present embodiment, so that the refrigerator thermometer both may be used
It is used, is used on the partition that can also be placed in refrigerator, therefore user can be according in refrigerator on the hanging rod in refrigerator with hanging over
