Description

With the camera of heating arrangement

Technical field

The utility model relates to a kind of camera with heating arrangement.

Background technology

Camera head (camera) uses comparatively frequent in daily life, and it generally comprises housing, arranges opening on front side of housing, and opening part arranges clear glass eyeglass, arranges each components and parts in housing.In use procedure, in especially winter, owing to generating heat after the components and parts work in housing, cause enclosure interior space and the external world to occur the temperature difference, now clear glass eyeglass place is due to the temperature difference, easily occurs atomizating phenomenon, affects the normal use of camera head.

Utility model content

The purpose of this utility model is exactly to solve the problem, and provides a kind of camera with heating arrangement.

To achieve these goals, the utility model adopts following technical scheme: a kind of camera with heating arrangement, comprise tubular housing, the rear openings place of described housing removably arranges bonnet, the front openings place of described housing arranges clear glass eyeglass, and described housing, bonnet and clear glass eyeglass form accommodation space jointly, arrange shooting components and parts in described accommodation space, it is characterized in that

Described case top arranged outside, for gathering the first temperature sensor of ambient temperature, arranges the second temperature sensor for gathering accommodation space temperature inside described case top;

The single-chip microcomputer of effect control center is set in described accommodation space;

Arrange the heating arrangement be made up of accumulator, switch and electrical heating wire in described accommodation space, described accumulator, switch and electrical heating wire connect successively;

Described clear glass eyeglass is rounded, and described clear glass eyeglass arranges concave ring groove near periphery, and described electrical heating wire is arranged in concave ring groove, and the oral area of described concave ring groove arranges insulation crystalline ceramics ring;

Wherein, described first temperature sensor, the second temperature sensor and switch are all connected to single-chip microcomputer.

Preferably: described electrical heating wire cross section is square.

Compared with prior art, the utility model has following beneficial effect: the utility model can heat clear glass eyeglass, the clear glass lens atomization problem effectively preventing accommodation space internal-external temperature difference from causing.

Accompanying drawing explanation

Fig. 1 is the camera clear glass eyeglass schematic front view with heating arrangement in embodiment.

Fig. 2 is the camera cross-sectional schematic with heating arrangement in embodiment.

Description of reference numerals: 1 clear glass eyeglass, 2 insulation use crystalline ceramics ring, 3 electrical heating wires.

Embodiment

The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.

See Fig. 1 and Fig. 2, a kind of camera with heating arrangement, comprise tubular housing, the rear openings place of described housing removably arranges bonnet, the front openings place of described housing arranges clear glass eyeglass, described housing, bonnet and clear glass eyeglass form accommodation space jointly, shooting components and parts are set in described accommodation space, described case top arranged outside, for gathering the first temperature sensor of ambient temperature, arranges the second temperature sensor for gathering accommodation space temperature inside described case top; The single-chip microcomputer of effect control center is set in described accommodation space; Arrange the heating arrangement be made up of accumulator, switch and electrical heating wire in described accommodation space, described accumulator, switch and electrical heating wire connect successively; Described clear glass eyeglass is rounded, and described clear glass eyeglass arranges concave ring groove near periphery, and described electrical heating wire is arranged in concave ring groove, and the oral area of described concave ring groove arranges insulation crystalline ceramics ring; Wherein, described first temperature sensor, the second temperature sensor and switch are all connected to single-chip microcomputer.Described electrical heating wire cross section is square.

Principle of work: after the difference between the temperature that the first temperature sensor and the second temperature sensor detect is greater than preset value (such as preset value is 5 degree), Single-chip Controlling heating arrangement work (heating-up temperature of heating arrangement is greater than the temperature that the second sensor detects), prevents clear glass eyeglass place from hazing after heating arrangement work.After difference between the temperature that the first temperature sensor and the second temperature sensor detect is less than preset value (such as preset value is 5 degree), Single-chip Controlling heater stop works.

The foregoing is only preferred implementation of the present utility model, protection domain of the present utility model is not limited in above-mentioned embodiment, and every technical scheme belonging to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, the some improvement carried out under the prerequisite not departing from principle of the present utility model, these improvement also should be considered as protection domain of the present utility model.
