Arrive shown in Figure 6 like Fig. 1; A kind of automatic regeneration moisture absorption apparatus; Form by mounting box 1, controller 2, moisture absorption apparatus 3, valve 4, spring 5, memory spring 6, moisture probe 7, ptc heater 8; Mounting box 1 comprises inner box 11 and outer box 12; Described controller 2 is placed in the inner box 11, and described inner box 11 fastens dehumidifier space 13 of formation with outer box 12, and described moisture absorption apparatus 3, valve 4, spring 5, memory spring 6 are placed in the dehumidifier space 13; The both sides, inside of described inner box 11 are respectively equipped with one group to the oblique retaining 112 of the U-shaped sealing of the perpendicular retaining of the U-shaped of the inner box of mounting box inner process sealing 111, inner box, tiltedly are provided with inner box passage 113 on the inner box wall between the retaining 112 at the perpendicular retaining 111 of U-shaped sealing of each group inner box and the U-shaped sealing of inner box; The both sides of box 12 are respectively equipped with one group to the oblique retaining 122 of the U-shaped sealing of the perpendicular retaining of the U-shaped of the outer box of mounting box inner process sealing 121, outer box outside, box passage 123 outside on the oblique outer box wall that keeps off between 122 of U-shaped sealing of the perpendicular retaining 121 of U-shaped sealing of the outer box of each group and outer box, being provided with.
The perpendicular retaining of the U-shaped of described inner box sealing 111 is vertical with the mounting box inwall, the U-shaped sealing of described inner box tiltedly the U-shaped sealing of the angle that forms of two sides and two sides of the perpendicular retaining 111 of U-shaped sealing of inner box of retaining 112 and described inner box tiltedly tiltedly to keep off the angle of the mounting box inwall formation that 112 base belongs to identical with the U-shaped sealing of inner box respectively three limits of retaining 112; The perpendicular retaining of the U-shaped of described outer box sealing 121 is vertical with the mounting box inwall, the U-shaped sealing of described outer box tiltedly the U-shaped sealing of retaining 122 and inner box tiltedly keep off 112 inner box and outside the joint face both sides of box be symmetric arrays.
Described valve 4 is placed in by the U-shaped sealing of the perpendicular retaining of the U-shaped of inner box sealing 111, inner box tiltedly in the U-shaped sealing spaces that tiltedly retaining 122 forms jointly of the perpendicular retaining 121 of U-shaped sealing and the outer box of retaining 112, outer box, and the U-shaped sealing that the axis of described valve 4 is placed in the perpendicular retaining of the U-shaped sealing that is positioned at inner box 111, the inner box tiltedly perpendicular retaining 121 of U-shaped sealing of retaining 112, outer box and the U-shaped of outer box seals the oblique valve draw-in groove 14 that keeps off 122 crossover locations.Valve 4 can rotate round axis.
Described spring 5 is positioned at outer box 12, connects the valve 4 that is positioned at 13 both sides, dehumidifier space; Described memory spring 6 is positioned at inner box 11, connects the valve 4 that is positioned at 13 both sides, dehumidifier space.
As shown in Figure 7, described moisture probe 7 is placed in the drier in the moisture absorption apparatus 3 with ptc heater 8.
Described memory spring 6 adopts electric energy to reset.
In the application of reality, mounting box 1 is fixed in the installing hole on the airtight wallboards of box body, make inner box 11 be positioned at casing, outer box 12 is positioned at outside the casing.The original state of memory spring 6 is a no power; The traction that valve 4 receives spring 5 compresses the perpendicular retaining 111 of U-shaped sealing of inner box, and the U-shaped sealing that compresses outer box simultaneously tiltedly keeps off 122, at this moment; Valve 4 is separated outer box passage 123 with moisture absorption apparatus 3 fully; And inner box passage 113 is communicated with moisture absorption apparatus 3, that is to say, moisture absorption apparatus 3 is isolated with the outer air of casing fully in this state; And the moisture content in the casing can get into moisture absorption apparatus 3 and the agent that is dried absorption from inner box passage 113, thereby makes the air in the casing dry gradually.
When controller 2 detects humidity value that moisture probe 7 returns greater than the predefined humidity upper limit, controller 2 is given memory spring 6 and ptc heater 8 power supplies, and memory spring 6 is shunk; The pulling force that overcomes spring 5 makes valve 4 upsets, and valve 4 compresses the perpendicular retaining 121 of U-shaped sealing of outer box, and the U-shaped that compresses inner box simultaneously seals tiltedly retaining 112; At this moment, valve 4 is separated inner box passage 113 and moisture absorption apparatus 3 fully, and outer box passage 123 is communicated with moisture absorption apparatus 3; That is to say; Moisture absorption apparatus 3 is in connected state with the outer air of casing, and at this moment, drier is under the heating of ptc heater; Moisture content constantly evaporates, from the air that outer box passage 123 gets into outside the casing.The water content that detects drier when moisture probe 7 is less than predefined humidity lower limit; Controller 2 will be to ptc heater and memory spring 6 outages, and valve 4 overturns once more, gets into moisture absorption process again; So move in circles, just can keep the drying of article in the casing.
Controller 2 also comprises the gauge tap 21 that is arranged on the shell 11; Display screen 22; People can be provided with the humidity upper limit and humidity lower limit through gauge tap 21 according to the classification and the quantity of stored article, and display screen 22 is used to show drying regime and the duty of automatic regeneration moisture absorption apparatus in the casing.
Adopt automatic regeneration moisture absorption apparatus of the present invention to be installed on the airtight casing and use, after drier has suctioned moisture content, do not need manual work to take out and carry out dried; This device can carry out drying to drier automatically; And moisture content is discharged in the outer air of casing, after the drier drying, can carry out drying to the air in the casing again; So move in circles, realize the article that store are carried out dry purpose.
Automatic regeneration moisture absorption apparatus of the present invention is than adopting the semiconductor dehumidifier sheet that the article in the casing are carried out drying, and energy consumption is more hanged down more environmental protection.Automatic regeneration moisture absorption apparatus of the present invention is compared with the moisture absorption apparatus that needs artificial treatment, does not need manual intervention, can carry out regeneration reducing to drier automatically.
The foregoing description only is to be used for interpretation purposes of the present invention, and is not to be limitation of the present invention, and those skilled in the art in essential scope of the present invention, make various variations or alternative, also should belong to protection category of the present invention.
