Description
Technical Field
The utility model relates to a dryer, in particular to a dryer.
Background
The dryer is especially a glass dryer, and is applied to the teaching field on a large scale, sealing agents such as vaseline can be uniformly coated between an outer body and a sealing cover for ensuring tightness, the sealing cover coated with the vaseline can only translate and rotate to open and close, a connecting valve can be arranged on the sealing cover or the outer body for improving air tightness of the existing vacuum (negative pressure) dryer, and a vacuum device is connected through the connecting valve.
Disclosure of Invention
The utility model aims to solve the technical problems that: in order to solve the dryer demand that current customer needs simple structure, convenient to use, can promote the leakproofness and be convenient for open and shut, provide a dryer.
The technical scheme adopted for solving the technical problems is as follows: the utility model provides a desicator, is used for placing the external body that is used for placing the drier by the drier lower floor including the upper strata to with set up the sealed lid on the external body, the vacuum pump is installed at the top of sealed lid, the vacuum pump includes the barrel with sealed lid sealing connection, barrel both ends opening and inside UNICOM, the front end of barrel has the extraction opening, extraction opening and external body UNICOM, the rear end of extraction opening has annular boss, places the elastic component on the boss, and the rear end of elastic component sets up at least one sealed pad, and the rear end of sealed pad sets up presses the pole, and the rear end demountable installation of barrel has the encapsulation circle, presses the pole setting in the inner circle of encapsulation circle.
Further, the elastic member is a mesh braid member or a spring member.
Further, the sealing gaskets comprise mounting rings, pressing rods are arranged in inner rings of the mounting rings, and at least one sealing groove for sleeving the sealing rings is formed in outer rings of the mounting rings.
Further, the sealing cover is also provided with a handle.
The utility model has the beneficial effects that the 'needle cylinder' capable of automatically rebounding is additionally arranged on the existing sealing cover capable of vacuumizing, the 'needle cylinder' is pressed before closing the cover, the 'needle cylinder' automatically rebounds after closing the cover, and air in the outer body is extracted into the 'needle cylinder', so that the pressure in the outer body is slightly negative pressure, and the sealing effect is improved (the sealing cover is more tightly attached with the outer body);
secondly, the needle cylinder is subjected to two sealing treatments, so that air in the outer body cannot flow from the needle cylinder to the outside, and meanwhile, the air in the outside cannot flow from the needle cylinder to the outer body.
When uncapping, press "cylinder" and press the air of extraction back in the external body for the external body no longer is negative pressure state, conveniently opens, need not current broken vacuum treatment, and current broken vacuum treatment needs to be to the dry thing adaptive operation, and the dry thing of one carelessly can pollute, and secondly introduces outside air and breaks the vacuum, can increase the consumption of drier, reduces the life of drier.
In conclusion, the utility model has the characteristics of simple structure, convenient use, good sealing performance and convenient opening and closing.
Drawings
The utility model will be further described with reference to the drawings and examples.
Fig. 1 is a schematic structural view of the present utility model.
