As depicted in figs. 1 and 2, Fig. 1 is the structural schematic diagram of the drying device in one embodiment, and Fig. 2 is shown in FIG. 1
The top view of drying device.Drying device includes drying box 100 and dehumidification module 200.Wherein, chamber is provided in drying box 100
Body 110 is provided with the first blow vent 120 and the second blow vent 130 of connection cavity 110 on drying box 100；Dehumidification module 200
Including at least two gas circuits 210, one end connects the first blow vent 120, the second ventilation of other end connection after two 210 parallel connections of gas circuit
Mouth 130, i.e., form circulating air duct, drying tower 220 be provided in circulating air duct between dehumidification module 200 and drying box 100.Work
When, workpiece is placed in cavity 110, due to forming circulating air duct between dehumidification module 200 and drying box 100, air is dry
Vapor is carried in dry case 100 to enter in drying box 100, is then dried in drying box 100, and the air after drying is again
It is secondary to enter in drying box 100, so that vapor in drying box 100 is gradual drying with circulating air duct.Due to being again introduced into
After air in drying box 100 is dehumidified the drying of module 200, rather than the air in the drying device external world, therefore extraneous
Air humidity has little effect the drying effect of the drying device in the present embodiment, can greatly improve the dry of drying box 100
Dry effect.
Since dehumidification module 200 includes at least two gas circuits 210, connection the first ventilation in one end after two 210 parallel connections of gas circuit
Mouth 120, the other end connect the second blow vent 130, therefore drying tower 220 can be arranged in two gas circuits 210 respectively.For example,

Gas circuit 210 where dry tower 220 is in off state.
For example, drying tower 220 can be regenerated by the way of freezing, heating or blowing.It is provided in drying tower 220
Reproducible hygroscopic agent.It is certain that the regeneration (regeneration of hygroscopic agent in other words) of drying tower 220 refers to that drying tower 220 absorbs
After steam, close to saturation state, the wettability power of hygroscopic agent substantially reduces the hygroscopic agent in drying tower 220, is needed at this time to dry
Hygroscopic agent in dry tower 220 is regenerated, and the hygroscopic water in hygroscopic agent is discharged, to make the activity of hygroscopic agent recovery moisture absorption.Example
Such as, hygroscopic agent can be molecular sieve, silica gel or activated alumina etc..It, will be in hygroscopic agent by way of freezing, heating or blowing
Hygroscopic water discharge, make hygroscopic agent restore again moisture absorption activity.Corresponding, each drying tower 220 is correspondingly arranged on regenerating unit,
Regenerating unit can be for example cooler, heater or hair-dryer, drying tower 220 be acted on by regenerating unit, to drying
Hygroscopic agent in tower 220 is regenerated.
For another example, in an application scenarios, one of drying tower 220 is during entire moisture absorption, due to drying tower
Hygroscopic agent in 220 causes the moisture absorption efficiency of the drying tower 220 to be gradually reduced after absorbing hygroscopic water, therefore can be dry with one wherein
Dry 220 wettability power of tower opens another gas circuit 210 when dropping to the half of initial value, i.e. dry in two gas circuits 210
Dry tower 220 works at the same time, and can guarantee the stability of dehumidification efficiency in entire drying device at this time；A drying tower wherein
After 220 wettability powers are substantially reduced, the drying tower 220 is made to be in reproduced state, another drying tower 220 also has relatively strong at this time
Wettability power, to ensure that the stability of entire drying device dehumidification efficiency；When the drying tower 220 in reproduced state is complete
When at regenerative process, which is again placed in absorptive work state, two drying towers 220 are in suction again at this time
Wet condition, so that drying device dehumidification efficiency is more stable.
In some embodiments, dehumidification module 200 includes the gas circuit 210 of several parallel connections, is provided in each gas circuit 210
Drying tower 220, for example, several drying towers 220 that can connect in each gas circuit 210, to improve the dehumidifying effect of dehumidification device.
And the control air valve 230 of independent control 210 on-off of gas circuit is provided in each gas circuit 210.Specifically, air valve 230 can be with
The both ends of the drying tower 220 of the gas circuit 210 are set, any end in 210 drying tower 220 of the gas circuit also can be set.
As shown in Fig. 2, blowing interlayer 140 and return air interlayer are provided in drying box 100 in one of the embodiments,
150, wherein blowing interlayer 140 is connected to the first blow vent 120 and cavity 110, return air interlayer 150 is connected to 130 He of the second blow vent
Cavity 110, blowing interlayer 140 and the setting of the interval of return air interlayer 150, workpiece can be placed on blowing interlayer 140 and return air interlayer
Between 150.For example, blowing interlayer 140 and return air interlayer 150 are arranged on two opposite inner walls of cavity 110, and drying
It is covered with air outlet on interlayer 140 and opposite two walls of return air interlayer 150, so that draught area is increased, so that in cavity 110
Air can sufficiently recycle.
As shown in figure 3, Fig. 3 is the structural schematic diagram of the drying box 100 in one embodiment.It is provided in drying box 100
Circulating fan 240 is specifically provided with circulating fan 240 in the circulating air duct of drying device, when starting circulating fan 240
Afterwards, the air flowing in the circulating air duct in drying device can be accelerated.
As shown in figure 3, be provided with heating device 260 in drying box 100, by heating device 260 in drying box 100 into
Row heating, heating device can control the heating temperature in drying box 100, so that the heating and temperature control is not damaging drying box
