Dampproof cover heater
Technical field
The present invention relates to a kind of use and help the heater that the water evaporates in the drier in dampproof cover is fallen, belong to the optimisation technique of dampproof cover.
Background technology
Drier in dampproof cover needs dry reduction after having adsorbed moisture content, dry by the mode of Exposure to Sunlight, affected by the factors such as weather, and efficiency is low, and dry reduction rate is slow.For example be used in the dampproof cover that prevents camera lens mildew on camera, when drier has adsorbed a large amount of moisture content and need to be dried, the speed of reducing by sun dehydration is too slow.Therefore, need to find a kind of more effective and weatherproof way that can help the desiccant dryness reduction in dampproof cover.
Summary of the invention
The object of this invention is to provide a kind of effective and weatherproof dampproof cover heater that can help desiccant dryness reduction in dampproof cover.
Technical scheme of the present invention is: dampproof cover heater, is mainly comprised of shell 1, heat-conducting plate 2, conductive plate 3, heater 4 and power plug 5; Shell 1 hollow, the roof of shell 1 is provided with the bayonet socket 11 to outer process; The cylindricality that bayonet socket 11 is hollow, heat-conducting plate 2 is placed in shell 1; An end face of heat carrier 2 is outside exposed by bayonet socket 11, other end and an end face laminating that is positioned at the conductive plate 3 of shell 1; On the wall of heat-conducting plate or conductive plate combination, be reserved with the groove that holds heater 4, heater 4 is placed in groove; On conductive plate, be provided with electric wire and draw hole; Power plug 5 is fixed on shell, and the part that is positioned at shell is passed electric wire by electric wire and drawn hole and be connected with heater, is positioned at part outside shell for being connected with external power source; During work, dampproof cover 7 is screwed on bayonet socket 11, makes the heat-conducting plate of dampproof cover 7 and 2 laminatings of the heat-conducting plate of dampproof cover heater, power plug 5 is inserted in supply socket and is switched on power, until complete dehumidifying.
The upper surface of described heat-conducting plate 2 is provided with the shrinkage pool 21 to lower recess, and when dampproof cover that camera is used is screwed in while dehumidifying on dampproof cover heater, the peephole on dampproof cover is unsettled in this shrinkage pool 21.
Hollow space filling heat insulating wall 6 in shell 1.
Heater 4 is selected ptc heater.
beneficial effect:
1,by dampproof cover being screwed on the bayonet socket of dampproof cover heater, after switching on power, heater work produces heat, and heat passes to the drier that has adsorbed a large amount of moisture content in dampproof cover by heat-conducting plate, make water evaporates in drier in air, help drier reduction.

Fig. 2 is that the present invention is for the cross-sectional view to the heating of camera dampproof cover.
The specific embodiment
As depicted in figs. 1 and 2, dampproof cover heater, is mainly comprised of shell 1, heat-conducting plate 2, conductive plate 3, heater 4 and power plug 5.
Shell 1 hollow, the roof of shell 1 is provided with the bayonet socket 11 to outer process; The cylindricality that bayonet socket 11 is hollow, heat-conducting plate 2 is placed in shell 1; An end face of heat carrier 2 is outside exposed by bayonet socket 11, other end and an end face laminating that is positioned at the conductive plate 3 of shell 1; On the wall of heat-conducting plate or conductive plate combination, be reserved with the groove that holds heater 4, heater 4 is placed in groove, face and the conductive plate of heater join, another face and heat-conducting plate join, and the heat that heater produces passes to the heat-conducting block of dampproof cover by heat-conducting plate, again and then pass to the drier in dampproof cover, after drier is heated, the moisture content of drier absorption is evaporated out, by the mesh on dampproof cover baffle plate, is evaporated in air and is gone.
On conductive plate, be provided with electric wire and draw hole; Power plug 5 is fixed on shell, and the part that is positioned at shell is passed electric wire by electric wire and drawn hole and be connected with heater, is positioned at part outside shell for being connected with external power source; During work, dampproof cover 7 is screwed on bayonet socket 11, makes the heat-conducting block of dampproof cover 7 and 2 laminatings of the heat-conducting plate of dampproof cover heater, power plug 5 is inserted in supply socket and is switched on power, until complete dehumidifying.
The upper surface of described heat-conducting plate 2 is provided with the shrinkage pool 21 to lower recess, and when dampproof cover that camera is used is screwed in while dehumidifying on dampproof cover heater, the peephole on dampproof cover is unsettled in this shrinkage pool 21, prevents that heat from causing damage to peephole.
Hollow space filling heat insulating wall 6 in shell 1, reduces the loss of heat, and the heat that heater is produced passes to the drier in dampproof cover by conductive plate and heat-conducting plate as much as possible, helps desiccant dryness reduction.
Heater 4 is selected ptc heater.
Above-described embodiment is only for interpretation purposes of the present invention, and is not limitation of the present invention, and those skilled in the art, in essential scope of the present invention, make a variety of changes or substitute, and also should belong to protection category of the present invention.
