A kind of dampproof cover drier
Technical field
The present invention relates to the heater that the water evaporates in a kind of drier with helping in dampproof cover is fallen, belonging 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, affect by factors such as weather, and efficiency is low, dry reduction rate is slow.Such as be used in dampproof cover camera preventing camera lens mildew, when drier has adsorbed a large amount of moisture content needs drying, the speed of being reduced by sun dehydration is too slow.Therefore, need to find a kind of more effective and weatherproof way that the desiccant dryness in dampproof cover can be helped to reduce.
Summary of the invention
The object of the invention is: a kind of effective and weatherproof dampproof cover drier that can help the reduction of desiccant dryness in dampproof cover is provided.
Technical scheme of the present invention is: a kind of dampproof cover drier, forms primarily 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 bayonet socket 11 outwardly; Bayonet socket 11 is the cylindricality of hollow, and heat-conducting plate 2 is placed in shell 1; An end face of heat-conducting plate 2 is outside exposed by bayonet socket 11, fits with an end face of the conductive plate 3 being positioned at shell 1 in other end; The wall that heat-conducting plate or conductive plate combine is reserved with the groove holding heater 4, and heater 4 is placed in groove, and a face of heater connects with conductive plate, and another face connects with heat-conducting plate; The heat that heater produces, is passed to the heat-conducting block of dampproof cover, and then passes to the drier in dampproof cover by heat-conducting plate, after drier is heated, the moisture content of drier absorption is evaporated, and is evaporated in air goes by the mesh on dampproof cover baffle plate.
Conductive plate is provided with electric wire and draws hole; Power plug 5 is fixed on shell, and the part being positioned at shell is drawn hole by electric wire through electric wire and is connected with heater, is positioned at part outside shell for being connected with external power source.
During work, dampproof cover is screwed on bayonet socket 11, the heat-conducting plate 2 of the heat-conducting plate of dampproof cover and dampproof cover drier is fitted, power plug 5 is inserted in supply socket and switches on power, until complete dehumidifying.
The upper surface of described heat-conducting plate 2 is provided with the shrinkage pool 21 to lower recess, when the dampproof cover of camera be screwed in dampproof cover drier dehumidifies time, the peephole on dampproof cover is unsettled in this shrinkage pool 21.
Hollow space filling heat insulating wall 6 in shell 1.
Beneficial effect:
1, by dampproof cover being screwed on the bayonet socket of dampproof cover drier, after switching on power, heater work produces heat, and heat passes in dampproof cover the drier having adsorbed a large amount of moisture content by heat-conducting plate, make water evaporates in drier in air, help drier reduction.

Detailed description of the invention
As depicted in figs. 1 and 2, dampproof cover drier, forms primarily 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 bayonet socket 11 outwardly; Bayonet socket 11 is the cylindricality of hollow, and heat-conducting plate 2 is placed in shell 1; An end face of heat-conducting plate 2 is outside exposed by bayonet socket 11, fits with an end face of the conductive plate 3 being positioned at shell 1 in other end; The wall that heat-conducting plate or conductive plate combine is reserved with the groove holding heater 4, heater 4 is placed in groove, a face of heater connects with conductive plate, another face connects with heat-conducting plate, the heat that heater produces, and is passed to the heat-conducting block of dampproof cover by heat-conducting plate, and then the drier passed in dampproof cover, after drier is heated, the moisture content of drier absorption is evaporated, and is evaporated in air goes by the mesh on dampproof cover baffle plate.
Conductive plate is provided with electric wire and draws hole; Power plug 5 is fixed on shell, and the part being positioned at shell is drawn hole by electric wire through electric wire and is connected with heater, is positioned at part outside shell for being connected with external power source; During work, dampproof cover is screwed on bayonet socket 11, the heat-conducting plate 2 of the heat-conducting block of dampproof cover and dampproof cover drier is fitted, power plug 5 is inserted in supply socket and switches on power, until complete dehumidifying.
The upper surface of described heat-conducting plate 2 is provided with the shrinkage pool 21 to lower recess, when the dampproof cover of camera be screwed in dampproof cover drier dehumidifies time, the peephole on dampproof cover is unsettled in this shrinkage pool 21, prevents heat from causing damage to peephole.
Hollow space filling heat insulating wall 6 in shell 1, reduce the loss of heat, the heat that heater is produced passes to the drier in dampproof cover as much as possible by conductive plate and heat-conducting plate, helps desiccant dryness reduction.
Ptc heater selected by heater 4.
Above-described embodiment is only used to interpretation purposes of the present invention, and is not limitation of the present invention, those skilled in the art, in essential scope of the present invention, makes a variety of changes or substitutes, also should belong to protection category of the present invention.
