Description
Technical field
The utility model relates to optical fields, more particularly to a kind of eyeglass demister.
Background technique
In the modern life, the ophthalmology problem of people is further frequent, for judging the fundus camera of eye pathologies situation
It is more more and more universal in various big hospital, and bring eyeglass hazes the solution never to improve therewith.
Fundus camera is divided into fixed and hand-held at present, and fixed fundus camera is placed in indoor fixed bit
It sets, since movement is constant, the excessively indoor equilibrium temperature of hospital's multi-pass expends come the room temperature for preventing eyeglass from hazing, and surely keeping steady fixed
A large amount of electric energy, does not meet the environmental protection concept advocated at present.If do not needed by temperature in equalization chamber in two season of winter in summer
One end time is stood after opening air-conditioning to wait for eyeglass elimination surface water mist quietly.
The phenomenon that hand-held fundus camera is due to daily carrying, the unfixed reason in place to use, and eyeglass is caused to haze
It is more serious, it is much the demister according to common spectacles at present, is mounted with electric heating wire on eyeglass to realize demisting.And
Fundus camera is completely high to the required precision of image, and holes installation electric heating wire can be to eyeglass in control image in eyeglass
Distortion have a great image, and install the effective area that can reduce eyeglass additional in lens surface.It is maintained by increasing lens area
The cost of original effective area is excessively high.
And the closed internal environment of fundus camera is not suitable for for fever metal being directly exposed in air environment, with dust
Contact is easy to produce electrostatic, and the safety of the acquisition and equipment to image all brings hidden danger.
Utility model content
In order to solve the above-mentioned technical problem at least one aspect, the utility model provide following solution.
A kind of eyeglass demister, including shell, the clamping button for connecting eyeglass, the electric heating wire being connected with the clamping button
Fixed strip, the electric heating wire being mounted in the electric heating wire fixed strip, the buffering being set on the electric heating wire fixed strip
Block is set to the intracorporal battery of shell, and the electric heating wire fixed strip is silica gel material, wraps up one layer of aluminium outside the electric heating wire
Metal coating shell processed.
Further, control switch is provided on the shell.
Further, at least two eyeglass demisters are provided on one piece of eyeglass in symmetrically placed.
Further, the battery is rechargeable battery.
Further, the battery is lithium battery.
Further, the buffer stopper is rigid plastics material.
The advantages of the utility model: fixing electric heating wire fixed strip by clamping button, allows electric heating wire fixed strip and mirror
The contact condition on piece surface is further adjusted, and electric heating fixed strip is allowed more to be bonded lens surface, facilitate it is thermally conductive, and
Installing aluminum metal coating shell additional outside electric heating wire contact silica gel need not with electric heating wire directly, while can use up maximum journey again
Degree conducts heat to silica gel from electric heating wire, facilitates the demisting of mirror surface;Setting buffer stopper make electric heating wire fixed strip not with shell
Body surface face directly contacts, and avoids the silica gel material due to electric heating wire fixed strip itself, excessively rubbing with surface of shell can lead
Silica gel fine grained chippings is caused to fall off, accumulation excessively will lead to the mobile track blocking of driving device;Battery uses chargeable form side
Electric energy supplement.

As depicted in figs. 1 and 2, it is arranged on the eyeglass 6 there are two the eyeglass demister being symmetrically installed, including shell 9,
The clamping button 1 for connecting eyeglass 6, the electric heating wire fixed strip 2 being connected with the clamping button 1, are mounted on the electric heating wire and fix
Electric heating wire 4 in item 2, the buffer stopper 5 being set on the electric heating wire fixed strip 2, the battery 8 being set in shell 9.
The clamping button 1 is flexible plastic material, for electric heating wire fixed strip 2 to be closely bonded 6 surface of eyeglass, institute
Stating electric heating wire fixed strip 2 is silica gel material, wraps up one layer of aluminum metal coating shell 3 outside the electric heating wire fixed strip 2 and is used for
It is thermally conductive.By the temperature of electric heating wire 4 by aluminum metal heat-conducting to silica gel, silica gel is thermally conductive to 6 surface of eyeglass, increases 6 table of eyeglass
The temperature in face realizes mirror surface demisting.
Clamping button 1 in the present embodiment has certain elasticity and preferable plasticity using elastic organic plastics material.
So, the contact condition with 6 surface of eyeglass can be further adjusted by fixed electric heating wire fixed strip 2, makes to adjust
It is more convenient.And the material with certain elasticity and plasticity can help electric heating wire fixed block to be preferably adjacent to eyeglass 6, make
Heating effect is more efficient, and defogging, effect of drying are more obvious.
And it is in order to avoid electric heating wire 4 directly connects with silica gel that one layer of aluminum metal coating shell 3 is wrapped up outside electric heating wire 4
Touching, due to the high-temperature of electric heating wire 4, directly contacting with silica gel can cause to damage to Silica Surface, and have very big safety hidden
Suffer from, installing aluminum metal additional keeps the heat transfer route between electric heating wire 4 and silica gel more smooth.
And electric heating wire fixed strip 2 select silica gel material be in order to by aluminum metal and electric heating wire 4 and external environment every
Absolutely, the dust avoided in air is contacted with metal, and especially the dust in the temperature and environment of itself superelevation of electric heating wire 4 connects
Touching can generate the internal electronic element of electrostatic hazard fundus camera, and excessively high take daily image of temperature can generate centainly
Interference, reduce the success rate of image recognition specific region, and have security risk.
Electric heating wire fixed strip 2 is contacted directly with 9 surface of shell by buffer stopper 5, it is saturating due to fundus camera
Mirror assembly belongs to moving condition, realizes the demister focused, therefore be located at 6 both ends of eyeglass by changing the distance between lens
There can be CONTACT WITH FRICTION with 9 inner surface of shell, need to be arranged buffer stopper 5 to reduce electric heating wire fixed strip 2 and 9 inner surface of shell
Contact;And the silica gel material of electric heating wire fixed strip 2 itself, excessively rubbing with 9 surface of shell will lead to silica gel fine grained chippings and falls off,
Accumulation excessively will lead to the mobile track blocking of driving device, and driving device is exactly that fundus camera changes distance between lens
Realize the device of focusing.
Further, opening and closing of control switch 7 (such as control button) realization to heater strip, In are set on shell 9
The electricity for saving battery can be closed in time after the completion of the work of 6 demisting of eyeglass.
Further, the battery 8 is rechargeable battery.The recycling for facilitating battery, the step of eliminating replacement.
Further, the battery 8 be lithium battery, lithium battery relative to other kinds of battery have it is low in cost,
The high feature of high reliablity, popularity rate is not in the problem of some compatibility in the technical solution of the utility model.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations;
Although the utility model is described in detail with reference to the foregoing embodiments, it will be understood by those of skill in the art that its according to
It can so modify to technical solution documented by previous embodiment, or part of technical characteristic is replaced on an equal basis
It changes;And these are modified or replaceed, various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
Spirit and scope.
