Embodiment
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1, the utility model comprises the housing 4 with air inlet 6 and air outlet 2, be provided with at the inner chamber of housing 4 and outside air imported via air inlet 6 and the fan 7 of being derived by air outlet 2, between air inlet 6 and air outlet 2 air mobile route on be also provided with heating element.
When fan 7 rotates, the air in housing 4 external world is imported the inner chamber of housing 4 by air inlet 6, and drive air to move along the inner chamber of housing 4, heating up through heating element heat absorption forms hot blast, is finally discharged by gas outlet 2.The hot blast of being discharged by housing 4 inner chamber is for brushing the protective cover glass 8 of camera, and the droplet that surface liquefaction of blowing off is formed, reaches the effect of demist.Simultaneously under hot wind action, above-mentioned protective cover glass 8 heats up, and effectively prevents droplet from continuing to be formed on surface.
In order to more effectively hot blast be guided to the surface of protective cover glass 8, on housing 4, the edge of air outlet 2 is also provided with wind deflector 1.The design reference camera inner space situation of wind deflector 1 and the installation site of this demister, resultant effect needs to ensure that hot blast blows with the angle necessarily tilted the surface pouring protective cover glass 8 after being flowed out by housing 4 inner chamber.
In the present embodiment, housing 4 comprises the mounting panel 4-1 being positioned at top and the base 4-2 being positioned at below, and both adopt multiple screw to be fixedly connected with.Top, the front-end and back-end of base 4-2 are all uncovered, mounting panel 4-1 comprises the horizontal plate body of covering base 4-2 open top and is positioned at the vertical plate body of horizontal plate body rear, covering base 4-2 rear end opening, namely the rear end that wherein air inlet 6 is located at the horizontal plate body of mounting panel 4-1 is positioned at the rear portion of housing 4 roof, and air outlet 2 is by the forward position of the horizontal plate body of mounting panel 4-1 and the front end of base 4-2 is uncovered forms.
The advantage of said structure design is adopted to be convenient to the installation of fan inside 7 and heating element and simplify the processing technology requirement of housing 4, the mounting panel 4-1 that split is arranged and base 4-2 can divide body formed, after fixing heating element and fan 7 are installed between, then screw is adopted to be fixed both.Like this, the difficulty of processing of housing 4 during integrated formed structure and the fussy degree of inner member installation is not only reduced, convenience when also ensure that inner member fault to a certain extent, demister dismounting safeguarded.
In the present embodiment, wind deflector 1 is formed in one in the wing plate stretched out obliquely in the horizontal plate body forward position of mounting panel 4-1.The design of integrated formed structure does not increase the difficulty of processing of mounting panel 4-1, and the angle of inclination of wing plate is determined by factors such as camera inner space situation and this demister installation sites.Resultant effect should be: after completing the installation of whole demister in camera, wind deflector 1 should setting angled with protective cover glass 8, after such hot blast is derived via air outlet 2, turn under the effect of wind deflector 1, hot blast brushes the surface of protective cover glass 8 at a certain angle, can ensure like this to blow the effect of drenching except droplet.
Actually arrange, fan 7 can adopt various structures form.In the present embodiment, fan 7 adopts the turbofan with advantages such as compact conformation, the volume of blast are large, and its entrance is connected with air inlet 6, export and point to air outlet 2.The gas flow of turbofan is perpendicular to rotating shaft, and outside air is sucked by air inlet 6, then is discharged by the outlet of turbofan, shifts to air outlet 2 through heating element.
In the present embodiment, heating element and fan 7 is all affixed is arranged on mounting panel 4-1, this improves the convenience that the assembling of whole demister is produced further.Particularly, heating element comprises the first heating element 3 and the second heating element 5, and both arrange and divide the both sides being positioned at the vertical median plane of housing 4 before and after the flow direction of air.
Mode that both above-mentioned first heating element 3 and the second heating element 5 are staggered front to back setting is the zigzag channel of air movement at housing 4 Inner Constitution, does not promote the overall width of housing 4, make structure become compact while increasing mobile route length.
Fig. 2 is using state figure of the present utility model, can find out: the demister in the technical program is arranged on the inside of camera, ensureing that hot blast brushes obliquely on the technical indicator basis of protective cover glass 8 surface (namely wind deflector 1 forms an angle close to protective cover glass 8 edge, with protective cover glass 8), the position of whole demister installation is comparatively flexible.For being arranged on the top of the cam lens group 9 of camera shown in figure, now hot blast blows the surface drenching protective cover glass 8 from top to bottom, it is conceivable that, this demister can also be set in other installation site, as carried out installing or be arranged on the inwall of camera protective cover at the sidepiece of cam lens group 9, be wherein excellent in the mode being arranged on cam lens group 9 top shown in Fig. 2, this sample demister can be followed above-mentioned lens group one and be installed in camera protective cover in the same way.
The temperature element 10 being used for testing environment temperature can also be installed in the present embodiment in camera protective cover, as temperature sensor, thermocouple etc., testing environment temperature arrives the dew point temperature Duan Shixiang controller (and control circuit board of camera) preset and sends signal, controller controls fan 7 and heating element start and stop according to preset rules, outside output or stopping supply hot blast are dynamic response processes.Said structure forms the responding device of automation, and therefore this demister has the ability from dynamic response, improves automaticity, without the need to manual intervention.
