Description

Structure improved moisture remover of dampproof box

Technical field

The utility model relates to a kind of moisture remover of dampproof box, particularly a kind of structure improved moisture remover of dampproof box.

Background technology

What all needs prevented that humidity from avoiding going mouldy shoots with video-corder the mechanical, electrical sub-vigour part of shadow, archives material or the like article as video camera, camera, CD disc record, computer magnetic butterfly sheet, family, the store method of people's first-selection is that they are placed in the moistureproof case that has dehydrating unit, to guarantee long preservation and use.Therefore the function perfection of moisture remover of dampproof box whether, the moistureproof effect on moisture extraction that directly has influence on whole moistureproof case whether rational in infrastructure, thus and then as can be known, depended on the quality of moisture effect by the anti-mildewy effect of stored goods.China utility model patent Granted publication CN2606285Y, disclose a kind of " moisture remover of dampproof box ", it comprises drying box, heating mechanism, the heat-conducting plate in drying box of upper and lower casing, band mesh, the upper and lower valve plate that is hubbed on the upper and lower casing upper and lower and a driving mechanism and a master control mechanism that is used for controlling heating mechanism and makes the driving mechanism effect by this that is made of sma coil and extension spring.This patented technology scheme is for the moistureproof dehydrating unit of existing moistureproof case, certain contribution arranged aspect the effect on moisture extraction improving.Yet it is objectively having the following disadvantages: at first, when heating mechanism adstante febre, need the drier in the drying box, heat-conducting plate and guide duct heat together, known, the contraction of sma coil needs certain high temperature, so because the ratio of heat capacities of this structure is bigger, longer from beginning to be heated to the time that sma coil shrinks fully, also cause sma coil longer from beginning to be retracted to the complete perisystolic time, outside during this period moisture can enter dehydrating unit by the hole on the lower house in a large number, enter in the moistureproof case by the hole on the upper shell again, cause the moisture of moistureproof case in heating process to rise significantly, can't reach the purpose of accurate controlled humidity; Secondly, mechanism stops adstante febre when heating, drier in the drying box, heat-conducting plate and guide duct are dispelled the heat together, known, sma coil is drawn back to be needed temperature to return to approach normal temperature, because the ratio of heat capacities of this structure is bigger, longer from stopping to be heated to the time that sma coil is fully withdrawn, also cause sma coil longer from the time that begins to draw back before being fully withdrawn, outside during this period moisture can enter dehydrating unit by the hole on the lower house in a large number, enter in the moistureproof case by the hole on the upper shell again, cause the moisture of moistureproof case in heating process to rise significantly, can't reach the purpose of accurate controlled humidity; Again, because drying box only has a pair ofly, effect on moisture extraction is not very good.

Summary of the invention

Mesh box 15 described in the utility model has three at least, four have been disclosed among the figure, they are fixed on respectively on the mesh box holder 20 that defaults in first cavity of resorption, 19 wall portions, but this fixed position and fixed form are not unique, for example also four mesh boxes 15 can be fixed on the wall body of first epicoele 7, be positioned at the cavity that constitutes jointly by the first upper and lower chamber 7,19 as long as guarantee mesh box 15 in a word.As shown in Figure 4, place the drier 16 that is used to absorb moisture in the mesh box 15, and the heating plate 17 that will be used to make drier 16 after making moist to return to drying regime places in each mesh box 15, and be embedded in the drier 16, heating plate 17 is electrically connected with control circuit board 11 by lead, and its heating beginning is controlled by control circuit board 11 fully with the time that heating stops.Heating plate 17 preferably adopts positive temperature coefficient ceramic heating plate PTC.Heat pipe 14 direct fixed connections are therein on the end face on a mesh box 15 box limits, heat pipe 14 both can be welding with the fixed connection mode of mesh box 15, it also can be riveted joint etc., both integral productions can also be formed, be formed with in the centre of heat pipe 14 and be used for the tube chamber that passes for memory alloy spring 12.

Memory alloy spring 12 described in the utility model is the short length of a kind of chance heat shrinkable, do not have hot temperature and can reply the metal of length, when mounted, memory alloy spring 12 is behind the tube chamber that passes heat pipe 14 centres, its two ends are connected with an end of a pair of upper and lower valve block 1,2 respectively, and the other end of a pair of upper and lower valve block 1,2 is connected with the two ends of a tension spring 13 respectively.When work, memory alloy spring 12 can produce flexible according to temperature control, and a pair of upper and lower valve block 1,2 is rotated; And when memory alloy spring is not heated the answer normal length, then by a pair of upper and lower valve block 1,2 of tension spring 13 tensions.

Control circuit board 11 of the present utility model is built in the lid chamber that is made of second 10,26 common cooperations of upper and lower chamber.Further it both can be fixed on the chamber wall of second epicoele 10, also can be fixed on the chamber wall of second cavity of resorption 26, can also be separately fixed on the chamber wall in the second upper and lower chamber 10,26.Control circuit board 11 is connected with power supply by circuit.Here need to prove: because directly acquisition easily from the market of control circuit board 11, as selecting the model of being produced by the dynamo-electric Co., Ltd of the logical profit in Changshu City, Jiangsu Province, China for use is the moistureproof case control circuit board of CTA.0, therefore, the applicant here repeats no more.

Narrate the course of work of the present utility model below in conjunction with Fig. 2, Fig. 3:

At first, see also Fig. 2, when not heating, according to lever principle, on tension spring 13 tensions are a pair of, lower disc 1,2 one sides, on a pair of, lower disc 1, the 2 a pair of axle ears by two ends rotate, stretching memory alloy spring 12, cause a pair of on, lower disc 1, one of 2 sides and the 3rd, the 4th baffle plate 22,24 closely contacts, with the 3rd, four- way pore 21,23 close, with entering of isolated outside air, meanwhile, four mesh box 15 interior drier 16 utilize first, second passage 5, the moisture in the moistureproof case can be fully absorbed in the 9 convection circulation effects that produce.

Then, see also Fig. 3, when drier 16 absorption moistures reach capacity, at this moment make the heating plate 17 in the mesh box 15 be in heated condition by control circuit board 11, by heating plate 17 with heat transferred heat pipe 14, by heat pipe 14 heat is passed to memory alloy spring 12 again, memory alloy spring 12 is in the after-contraction of being heated, strain a pair of on, lower disc 1,2 opposite sides, make a pair of on, lower disc 1,2 opposite sides and first, second baffle 6,8 closely contacts, with first, second passage 5,9 close, with the gas in the isolated moistureproof case, meanwhile, utilize the 3rd adding the drier of pining for 16, four-way pore 21, the 23 convection circulation effects that produce can be got rid of the moisture content in the drier 16.

Because the thermal capacity of the utility model structure is less, when in heating, the temperature in the heat pipe 14 can rise rapidly, and memory alloy spring 12 is shunk rapidly.And when stopping to heat,, adding that the passage on the mesh box 15 is convenient to circulation of air because the thermal capacity of the utility model structure is little, the temperature in the heat pipe 14 can descend rapidly, and memory alloy spring 12 is drawn back rapidly.
