The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the present disclosure, unless otherwise specified, terms of orientation such as "upper, lower, left, right, top, bottom" are used based on the definition of fig. 1, and specifically refer to the drawing direction of fig. 1. "inner and outer" refer to the inner and outer contours of each component part itself. The terms "first, second, etc. are used herein to distinguish one element from another, and are not intended to be sequential or important. Furthermore, in the following description, when referring to the drawings, like reference numbers in different drawings denote like elements.

According to the specific embodiment of the present disclosure, there is provided a glass frit way structure, as shown in fig. 1, the glass frit way structure includes a crucible having a cavity and a glass frit way 1 penetrating through the cavity, the cavity is filled with a thermal insulation medium 2 wrapping the glass frit way 1, the crucible includes a crucible cover 3 and a crucible body 4 defining the cavity together with the crucible cover 3, the crucible cover 3 is disposed on an upper portion of the crucible body 4, a lower end of the crucible cover 3 has a contact surface 31 contacting the thermal insulation medium 2, and a thickness of the crucible cover 3 at a corresponding portion of the contact surface 31 is gradually reduced from two sides to the middle.

Through the technical scheme, in the glass frit way structure that this disclosure provided, crucible cover 3 reduces from both sides to the centre at the thickness of the part that contact surface 31 corresponds gradually, like this, while guaranteeing the heat preservation effect of crucible, can alleviate the deformation degree of crucible cover 3 self under the high temperature state, namely, alleviate the deformation degree of crucible cover 3 at the part that contact surface 31 corresponds, thereby alleviate the deformation of glass frit way 1 that leads to through heat preservation medium 2 because the deformation of crucible cover 3, thereby prolong the life of glass frit way 1, simultaneously because the deformation of crucible cover 3 at the middle part that contact surface 31 corresponds the part is the biggest, consequently the thickness of this application crucible cover 3 middle part is thinnest, the deformation of crucible cover 3 that can the at utmost reduces.

The thickness of the crucible cover 3 is a thickness in the vertical direction as shown in fig. 1. The two sides of the crucible cover 3 may mean that the crucible cover 3 is located at the two sides in the extending direction of the glass material path 1, and thus the center of the crucible cover 3 means the upper side corresponding to the vicinity of the axis of the glass material path 1. Of course, the two sides of the crucible cover 3 can also mean that the crucible cover 3 is located at two sides perpendicular to the extending direction of the glass material channel 1, so that the crucible cover 3 can still reduce the deformation degree thereof, and further reduce the extrusion on the glass material channel 1.
