Abstract
The utility model is specifically related to the improvement of monocular structure, and object is to provide a kind of antifog monocular.Described monocular comprises lens barrel housing, described lens barrel housing is provided with the cavity be made up of lens barrel housing evagination, and USB well heater is provided with on the madial wall of this cavity, also be provided with thermofin between described USB well heater and lens barrel housing, the USB interface of described USB well heater is stretched out outside lens barrel housing.The evolution of heat when USB well heater is connected with external power source, can make the gas temperature of lens barrel housing and enclosure interior rise, thus conduct heat on eyeglass, the fog on eyeglass be evaporated, therefore makes this monocular have anti-fog function.
Description
Technical field
The utility model belongs to optical instrument field, particularly relates to a kind of monocular with anti-fog function.
Background technology
During the place use telescope that people are lower in environment temperature or humidity is larger, the eyeglass being positioned at lens barrel two ends very easily hazes, and has had a strong impact on telescopical normal use.If with cloth or lens paper wiping eyeglass, easily make pad pasting on eyeglass cause wearing and tearing, decrease the serviceable life of eyeglass.Therefore, existing telescope defogging method normally solves by special heating tape is wrapped in lens barrel outside, but heating tape is wrapped in lens barrel outside, heat transfer efficiency is not high, heat utilization ratio is low, and uses this heating tape also to need supporting power supply and power lead, is not easy to carry.
Utility model content
The purpose of this utility model is to provide a kind of lens barrel inside and has USB well heater, antifog monocular easy to use.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of antifog monocular, comprise lens barrel housing, described lens barrel housing is provided with the cavity be made up of lens barrel housing evagination, and USB well heater is provided with on the madial wall of this cavity, also be provided with thermofin between described USB well heater and lens barrel housing, the USB interface of described USB well heater is stretched out outside lens barrel housing.
Preferably: described thermofin is rubber layer.
Preferably: described USB well heater comprises cellular substrate, electrical heating wire is installed with in the bee-hole of described cellular substrate.
Preferably: described cellular substrate is ceramic substrate.
Preferably: the one side that described ceramic substrate is connected with thermofin is hair side.
The utility model has following beneficial effect:
1. because USB well heater is arranged on lens barrel inside, and outer wrap has thermofin, and the heat overwhelming majority that USB well heater produces can be stayed lens barrel inside and heat the gas of lens barrel and lens barrel inside, improves the efficiency of heating surface and energy use efficiency.Meanwhile, because USB well heater is arranged in the lug boss of lens barrel, light passing through in telescope can not be stopped.
2. adopt USB interface to power to USB well heater, do not need to carry special equipment, easy to use.
3. thermofin preferred rubber, had both had good effect of heat insulation, again with the function of buffering.
4., as preferred embodiment, the substrate of USB well heater adopts honeycomb, improves the rate of heat exchange of gas in USB well heater and lens barrel, thus accelerates the speed of demist.
5. preferably ceramic is as the substrate of USB well heater, has the advantages such as heat transfer is fast, heating is even, working stability, life of product are long.
6. the one side be connected with thermofin due to ceramic substrate is hair side, is beneficial to it and thermofin is bonding, is convenient to processing and fabricating.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the cut-open view of A-A line in Fig. 1.
Embodiment
As shown in Figures 1 and 2, a kind of antifog monocular, comprise lens barrel housing 1, eyepiece and object lens are arranged on the two ends of lens barrel housing 1, lens barrel housing 1 is provided with the cavity be made up of lens barrel housing 1 evagination, and the USB interface 4 being provided with USB well heater 2, USB well heater 2 on the madial wall of this cavity is stretched out outside lens barrel housing 1.When eyeglass hazes, USB well heater 2 is connected with external power source by USB interface 4, and the gas of heating lens barrel and lens barrel inside, makes the temperature of telescope disk rise, thus the fog on removing eyeglass.Owing to being also provided with thermofin 3 between USB well heater 2 and lens barrel housing 1, it is outside that the heat that USB well heater 2 is produced not easily is lost to lens barrel housing 1, improves the efficiency of heating surface and energy utilization rate.Meanwhile, because USB well heater 2 is arranged in the cavity of lens barrel housing 1 evagination, light passing through in telescope can not be stopped, thus not disturb telescopical normal use.Described external power source is portable power source, is easy to carry.
The present embodiment preferred rubber, as thermofin 3, had both had good effect of heat insulation, again with the function of buffering.USB well heater 2 comprises cellular substrate simultaneously, is installed with electrical heating wire in the bee-hole of cellular substrate, improves the rate of heat exchange of gas in USB well heater 2 and lens barrel, thus accelerates the speed of demist.In addition, cellular substrate also have that intensity is high, good toughness, not yielding, resistance to compression, shock resistance, the advantage such as saving material.
Further preferably the present embodiment adopts ceramic substrate as cellular substrate as of the present utility model, make USB heating element conduct heat fast, heating evenly, working stability, improve demisting efficiency and extend life-span of product.The one side that ceramic substrate is connected with thermofin 3 is set to hair side, uses bonding agent to bond more closely by it with when thermofin 3 bonds, be convenient to processing and fabricating.
The core of the utility model only with regard to improving is set forth, and as the concrete layout of other assemblies of the antifog telescope of this monotubular, comprises concrete structure and the mounting means of eyepiece and object lens; And the concrete structure etc. of USB well heater is not then core of the present utility model, those skilled in the art are with reference to prior art or improvement further.
