Description

Technical Field

[0001] The utility model relates to an experimental device, in particular to a glass dryer. Background Art

[0002] Glass desiccator is one of the necessary glassware in the laboratory, and is widely used in the fields of chemistry, chemical engineering, biology, medicine, etc. It is used to dry and store materials that are easy to deliquesce and deteriorate, and is widely used in various experiments.

[0003] The base and the main body of the existing glass dryer are integrally formed, and a ceramic isolation plate is placed in the middle to divide the glass dryer into a material chamber and a drying chamber. Since the desiccant is placed in the drying chamber of the glass dryer, each time the desiccant needs to be replaced, the ceramic isolation plate placed above the desiccant and the material on the ceramic isolation plate must be taken out before the desiccant can be taken out for replacement. This operation is not only time-consuming and laborious, affecting the progress of the experiment, but also causes the material to be out of the dry environment, which may cause the loss or deterioration of the material, affecting the precision and accuracy of the experiment.

[0004] At present, a Chinese patent with authorization announcement number CN220663302U in the existing patents discloses a glass dryer, including a glass container and a glass sealing cover. The glass container is loaded with a desiccant carrier piston at the bottom of the glass container. The desiccant carrier piston can be directly loaded and replaced with desiccant from the bottom of the glass container, further shortening the time for replacing the desiccant, reducing the contact between the material and the outside air, and improving the drying efficiency.

[0005] However, due to its structural problems, the amount of desiccant loaded in the desiccant carrier piston is limited, resulting in frequent replacement of the desiccant, affecting the progress of the experiment, and it is impossible to avoid contact between the material and the outside air when replacing the desiccant carrier piston. Summary of the invention

[0006] A glass dryer comprises a cover, a main body and a base, wherein the cover is sealingly covered on the upper opening of the main body, and the main body is rotatably sealingly covered on the base, the main body is provided with a material cavity for placing materials, and the base is provided with a drying cavity for placing desiccant; a lower platform is provided at the bottom of the main body, and a plurality of first air holes are arranged on the lower platform; an upper platform is provided at the top of the base, and a plurality of second air holes matched with the first air holes are arranged on the upper platform; the upper platform and the lower platform are rotated to control the connection between the first air holes and the second air holes, so as to realize the connection between the material cavity and the drying cavity.

[0007] Preferably, the lower edge surface of the cover body and the upper edge surface of the main body are both frosted surfaces, and the frosted surfaces are sealed by a sealant.

[0008] Preferably, the first ventilation holes and the second ventilation holes are evenly spaced and distributed along the circumferential direction, and the cross-sections of the first ventilation holes and the second ventilation holes are any one of triangle, square, circle or other polygons.

[0009] Preferably, an upper clamping groove having a positioning function is provided on the lower outer edge of the lower platform, and a lower clamping groove matching with the upper clamping groove is provided on the top of the upper platform.

[0010] Preferably, the contact surfaces of the upper clamping groove and the lower clamping groove are frosted surfaces sealed with a sealant.

[0011] Preferably, the upper platform and the lower platform are in close contact, and the contact surface between the upper platform and the lower platform is a frosted surface coated with a sealant.

[0012] Preferably, the outer walls of the main body and the base have markings for determining whether the first vent hole and the second vent hole are connected or not, and the outer wall of the base is provided with a first lower marking representing "open" and a second lower marking representing "closed".

[0013] Preferably, the upper mark is “▽” or any other directional expression symbol.

[0014] Preferably, the first lower mark is "O" or any other symbol representing "on", and the second lower mark is "C" or any other symbol representing "off".

[0015] Preferably, a push-pull drawer is provided in the drying chamber, the drawer is provided with a containing cavity for carrying the desiccant, and the drawer is sealedly connected to the base.

[0016] Preferably, the drawer and the drying chamber have matching card slots, and the surface of the card slot is sealed by a sealant.

[0017] Preferably, the base is made entirely of transparent glass, which facilitates observation of color changes of the desiccant and timely replacement.

[0018] Preferably, an upper handle is symmetrically provided on the outer wall of the main body, and a lower handle is symmetrically provided on the outer wall of the base, and the upper handle and the lower handle are any of pull rings, pull handles, and other shapes of protrusions or depressions.

[0019] Preferably, the end surface of the bottom of the base that contacts the desktop is provided with anti-skid grooves or any other structure with anti-skid effect.

[0020] In summary, the utility model has the following beneficial effects:

[0021] (1) By setting a drawer for holding desiccant at the base, the desiccant can be replaced without opening the cover to take out the material and the isolation plate, which is more efficient and convenient, and the operation is safer.

[0022] (2) The drawer structure can hold more desiccant, which can effectively reduce the frequency of replacing desiccant and save the cost of desiccant drying.

[0023] (3) By controlling the opening and closing of the first and second vent holes, the contact between the material and the outside air is avoided when the desiccant is replaced, thereby effectively preventing the loss and deterioration of the material. BRIEF DESCRIPTION OF THE DRAWINGS
