Description
Technical field
The utility model relates to field, antifog chamber, relates in particular to a kind of multistage antifog cold chamber.
Background technology
The equipment such as video camera, outdoor lamp and outdoor projector carry out in use procedure often using anti-fogging equipment to carry out antifog processing, will reduce the working effect of equipment or cause equipment to work preventing because producing fog.At present, of a great variety for the anti-fogging equipment of different components, function and effect are also uneven.
Chinese patent literature publication number 202843566U discloses a kind of electric video laryngoscope anti-smog device; be characterized in: by the heating component that is arranged on camera assembly front end, formed; described heating component consists of circuit board and the upper heating element that is arranged on circuit board, and described heating element is inlaid in camera lens over cap.
This utility model is by camera assembly front end, heating component being set, by heating make laryngoscope blade inside and outside be difficult to form the temperature difference, avoided forming water smoke in the end of laryngoscope blade.Because the temperature of outdoor environment is constantly to change, if will playing good heating effect, heating component needs a set of comparatively complicated temperature control system, significantly having improved the cost of anti-fogging equipment, and heating component meeting consumed energy, also can affect to being heated the life-span of equipment.
Utility model content
In order to overcome the defect of prior art, technical problem to be solved in the utility model is to propose a kind of multistage antifog cold chamber, and it is simple in structure, is easy to make, and has good anti-fog effect, and there is no energy loss.
For reaching this object, the utility model by the following technical solutions:
A kind of multistage antifog cold chamber that the utility model provides, comprise housing and seal pad, described seal pad is positioned at the inside of described housing, the opening part of described housing is provided with transparency cover, described transparency cover comprises the first hyaline layer, the second hyaline layer and interlayer, described interlayer is between described the first hyaline layer and described the second hyaline layer, described the first hyaline layer, described the second hyaline layer and described interlayer surround the first cavity, and described the second hyaline layer, described seal pad and described housing surround the second cavity.
Preferred version of the present utility model: described the first cavity and/or described the second cavity are vacuum chamber.
Preferred version of the present utility model: the inside of described the first cavity and/or described the second cavity is filled with low thermal conductivity gas.
Preferred version of the present utility model: described heater element is video camera or illuminating lamp.
Preferred version of the present utility model: described the first hyaline layer and described the second hyaline layer are made by glass or organic glass.
Preferred version of the present utility model: described interlayer is made by rubber.
Preferred version of the present utility model: described seal pad middle part be fixed with heater element.
The beneficial effects of the utility model are:
The utility model being provided with has the transparency cover of the first cavity, because the temperature conductivity of the first cavity is lower, make the heat of the second cavity inside medium be difficult to be passed to the first hyaline layer, even if external environment and heater element have the larger temperature difference, but the temperature difference of the surfaces externally and internally of the first hyaline layer directly contacting with external environment is also not obvious, therefore the surface of the first hyaline layer is difficult for forming water smoke.In addition, heater element is arranged in the second cavity, the second cavity is that vacuum chamber or its inside are filled with low thermal conductivity gas, the heat being sent by heater element is difficult to be passed to the second hyaline layer, therefore the first cavity and the second cavity form a multistage heat shield, have strengthened greatly antifog ability of the present utility model.In addition, the utility model also has simple and compact for structure, the low features such as making that are easy to of cost.
Accompanying drawing explanation
Fig. 1 is the cut-open view in the multistage antifog cold chamber that provides of the utility model embodiment.
In figure:
1, housing; 2, seal pad; 3, heater element; 41, the first hyaline layer; 42, the second hyaline layer; 43, interlayer; 5, the first cavity; 6, the second cavity.
Embodiment
Below in conjunction with accompanying drawing and by embodiment, further illustrate the technical solution of the utility model.
As shown in Figure 1, be the cut-open view in the multistage antifog cold chamber that provides in present embodiment.
A kind of multistage antifog cold chamber providing in the present embodiment, comprise housing 1 and seal pad 2, seal pad 2 is located at described housing 1 inside, the middle part of seal pad 2 is provided with for the fixing mounting hole of heater element 3, the opening part of housing 1 is provided with transparency cover, and transparency cover has two effects, and the one, prevent from forming water smoke, the 2nd, prevent that extraneous steam or dust from entering the cavity of housing 1 inside, thereby the heater element 3 of housing 1 inside can be worked.
Transparency cover shape can be circular, square or other shapes, transparency cover comprises the first hyaline layer 41, the second hyaline layer 42 and interlayer 43, interlayer 43 is circular, it is between the first hyaline layer 41 and the second hyaline layer 42, the first hyaline layer 41, the second hyaline layer 42 and interlayer 43 surround the first cavity 5, the second hyaline layers 42, seal pad 2 and housing 1 and surround the second cavity 6.The temperature conductivity of the first cavity 5 is lower, makes the heat of the second cavity 6 inside be difficult to be passed to the first hyaline layer 41.Therefore, even if external environment and heater element 3 have the larger temperature difference, but the heat that heater element 3 sends is difficult to along the azimuth travel at transparency cover place, therefore first inside surface of hyaline layer 41 directly contacting with external environment and the difference variation of outside surface are also not obvious, the surface of the first hyaline layer 41 is difficult for forming water smoke.
In addition, housing 1 and seal pad 2 all have good sealing effectiveness, therefore the steam of external environment condition is the internal cavities that is difficult to enter housing 1, therefore heater element 3 surfaces can not produce water smoke yet.
In the present embodiment, being preferably one of the first cavity 5, second cavity 6 both or both is vacuum chamber.Also can be that the inside of one of the first cavity 5, second cavity 6 both or both is filled with low thermal conductivity gas.Low thermal conductivity gas refers to that temperature conductivity is not higher than the gas of air temperature conductivity.Because the temperature conductivity of air itself is not high, therefore in the not high occasion of antifog effect requirements, also can directly use air as the medium of the first cavity 5 and the second cavity 6 inside.
The present embodiment is preferably the first hyaline layer 41 and the second hyaline layer 42 is made by glass or organic glass, and in order not affect the light transmission of internal heating element 3, the first hyaline layer 41 and the second hyaline layer 42 should be selected as much as possible transmittancy good material is made.
The present embodiment is preferably interlayer 43 and is made by low thermal conductivity material, and the present embodiment more preferably interlayer 43 is made by low heat conductivity rubber.Adopting the low material object of temperature conductivity is in order to reduce the heat transmission of 42 pairs of the first hyaline layers 41 of the second hyaline layer, thereby further guarantees that the first hyaline layer 41 is not subject to the impact of the heat that heater element 3 sends.
Below only with embodiment, the utility model is illustrated, but the utility model is not limited to above-mentioned size and outward appearance illustration, more should not form any restriction of the present utility model.As long as within any improvement that the utility model is done or modification all belong to the protection domain of the utility model claim opinion.
