As shown in fig. 1 to 5, the moisture-absorbing, waterproof and breathable product is mainly installed in various electrical appliances 1 such as automobile appliances, outdoor appliances or household appliances. The product comprises a housing 2, each structure of which is mounted on the housing 2, and the housing 2 is mounted on the electrical equipment 1, and the embodiment is exemplified by being mounted inside the electrical equipment 1. One side (outer side) of the housing 2 is close to the outside of the electrical apparatus 1, and the other side (inner side) is close to the middle of the electrical apparatus 1.
Preferably, a plurality of air holes 8 are formed in the outer side surface and the inner side surface of the shell 2, and each air hole 8 is generally divided into a plurality of rows and a plurality of columns and can exchange air with the outside to discharge moist water vapor and introduce dry air, so that the balance of the internal pressure and the external pressure of the closed space in the shell is ensured.
It is further preferable that a waterproof breathable film 9 is mounted on the outer surface of the case 2, wherein the waterproof breathable film 9 can not only prevent external liquid, solid particles and the like from entering the inside of the case 2, but also maintain the breathable function. Further, if necessary, the waterproof breathable film 9 may be exposed to the outside of the electrical appliance 1.
A heating housing 3 is placed inside the casing 2. Wherein, protective cover 10 in the inboard opening of shell 2 and installing can open earlier in protective cover 10, will heat casing 3 and put into the inside of shell 2 from inboard opening part, protective cover 10 in closing again, then shell 2 and interior protective cover 10 can play the guard action to heating casing 3.
The heating element 4 is connected to the outside of the heating case 3, and the inside is filled with the drying material 5. Wherein, the heating element 4 is a heating film, a heating plate or other suitable elements, is connected with the electrical equipment 1, can rapidly generate heat after being electrified, and heats the heating shell 3; and the drying material 5 is selected to be a suitable material having a desorption regeneration function, i.e., a function of absorbing moisture at normal temperature and rapidly releasing the absorbed moisture upon heating.
Preferably, the heating case 3 is opened at the top thereof, and the shielding cover 11 is installed at the opening, so that the drying material 5 can be filled into the heating case 3 through the top opening and then the shielding cover 11 is covered for encapsulation.
An outer temperature control spring 12 and an outer diaphragm valve 6 are arranged on the outer side of the heating shell 3, the tail end of the outer temperature control spring 12 is connected with the outer diaphragm valve 6, and the contraction or the extension of the outer temperature control spring 12 can control the closing or the opening of the outer diaphragm valve 6.
