Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass technology, and in particular provides a vacuum glass. Background Technology
[0002] Vacuum glass is favored for its excellent heat and sound insulation properties. Vacuum glass mainly consists of two layers of glass, an airtight joint, supporting components between the glass layers, and an air-absorbing component.
[0003] The suction components ensure that the vacuum space between the glass plates maintains a reliable vacuum level. There are two main types of suction components: evaporative and non-evaporative. They are typically pre-pressed or sintered. Evaporative suction components, after activation, form an evaporative film (such as a barium film) that remains in the visible area of the glass, affecting the overall aesthetics. Non-evaporative suction components often use block structures (such as rings, discs, or encapsulated cylindrical shapes). Due to their shape limitations, they are difficult to adapt to ultra-thin glass designs, and the complex encapsulation process restricts production efficiency. Utility Model Content

[0036] Please refer to Figures 1 to 9 This application provides a vacuum glass, including two glass components 1 and an air suction component 2.
[0037] Two glass pieces 1 are disposed over each other to form a vacuum space between the two glass pieces 1, and each glass piece 1 has a sealing edge 2;
[0038] The suction element 2 has a needle-like structure, and at least one glass element 1 has a groove structure 5 for accommodating the suction element 2, the groove structure 5 being adjacent to the sealing edge 2.
[0039] Understandably, the sealing edge 2 is the area where the surfaces of the two glass pieces 1 connect. For vacuum glass, the edges of the glass pieces 1 should all be sealing edges 2, thus forming a closed space. Furthermore, when the two glass pieces 1 are closed together, a support member 4 is provided between them, using multiple support members 4 to provide support.
[0040] The groove structure 5 should be formed by the inward indentation of the surface of the glass part 1, and the groove structure 5 is arranged adjacent to the sealing edge 2. Here, the extension direction of the groove structure 5 can be parallel to the extension direction of the sealing edge 2, or it can be at a certain angle.
[0041] The suction component 2 has a needle-like structure. Here, the needle-like suction component 2 should be a structural component with a large difference between its length and inner diameter. Therefore, its overall structure is slender. In this way, in addition to absorbing excess gas in the vacuum space, it has better concealment. Furthermore, the groove depth of the groove structure 5 used to support the suction component 2 is also shallower.
[0042] The vacuum glass of this invention has a groove structure 5 provided on any one or two glass pieces 1, and the groove structure 5 is adjacent to the sealing edge 2. At the same time, the needle-shaped suction element 2 is placed in the groove structure 5. In this way, the space occupied is significantly reduced and concealed packaging is achieved. The vacuum glass has low obstruction in the transparent area and no or almost no defects in appearance, which can better meet the development direction of vacuum glass towards high light transmittance and thinness.
[0043] In some embodiments, the inner diameter of the suction element 2 is ≤2 mm.
[0044] Understandably, the inner diameter of the suction component 2 refers to the maximum dimension of the cross-section of the suction component 2. For example, if the cross-section of the suction component 2 is circular, then the inner diameter of the suction component 2 is the diameter of the circular cross-section; or, if the cross-section of the suction component 2 is square, then the inner diameter of the suction component 2 is the width dimension of the square cross-section; or, if the cross-section of the suction component 2 is irregular, then the inner diameter of the suction component 2 is the maximum dimension of the irregular cross-section.
[0045] In some embodiments, the cross-sectional shape of the suction element 2 includes one or more of polygons, circles, and ellipses.
[0046] Understandably, the cross-sectional shape of the suction component 2 can be polygonal, such as triangular, quadrilateral, pentagonal, etc.; of course, it can also be circular or elliptical, and the cross-sections of different sections of the suction component 2 can also be different shapes.
[0047] In some embodiments, the extension direction of the groove structure 5 is the same as the extension direction of the sealing edge 2, and the distance between the groove structure 5 and the sealing edge 2 is ≤2 mm.
[0048] Understandably, the extension direction of the groove structure 5 should be the same as the extension direction of the sealing edge 2, and should be parallel to the extension direction of the sealing edge 2. The distance between the groove structure 5 and the sealing edge 2 refers to the distance from the inner wall surface of the groove structure 5 to the edge of the sealing edge 2.
[0049] In some embodiments, the groove structure 5 includes an arc-shaped groove bottom wall and a vertical side wall connected to the arc-shaped groove bottom wall.
[0050] Understandably, the cross-sectional shape of the groove structure 5 is U-shaped, which makes it easier to process and can be directly formed by milling.
[0051] In some embodiments, the groove depth of the groove structure 5 is the same as the inner diameter of the suction member 2; and / or,
[0052] The width of the groove structure 5 is 1.1 to 1.3 times the inner diameter of the suction component 2.
[0053] Understandably, the groove depth of the groove structure 5 refers to the distance from the surface of the glass piece 1 to the bottom of the groove structure 5, and the groove width of the groove structure 5 refers to the width between the two vertical sidewalls.
[0054] The ratio of the groove width of the groove structure 5 to the inner diameter of the suction component 2 can be 1.1, 1.2, or 1.3.
[0055] In some embodiments, the number of suction elements 2 is multiple, and the number of groove structures 5 is the same as the number of suction elements 2, with each groove structure 5 arranged side-by-side and parallel to the same sealing edge 2; or...
[0056] Each groove structure 5 is arranged in parallel at the corresponding sealing edge 2.
[0057] Understandably, multiple groove structures 5 can be arranged side by side and parallel to each other at the same sealing edge 2. Alternatively, one or more groove structures 5 can be arranged at each sealing edge 2. That is, the suction components 2 can be concentrated at the same sealing edge 2 or dispersed at each sealing edge 2.
[0058] Please refer to the figure. In some embodiments, the suction member 2 includes a suction active part 6 and a protective layer part 7 covering the outer surface of the suction active part 6.
[0059] Understandably, the protective layer 7 is used to protect the gas-absorbing active part 6, which can be triggered by heating or magnetization. Here, the material of the gas-absorbing active part 6 is zirconium-based material, titanium-based material, tantalum-based material, needle-based material, etc.
[0060] In some embodiments, the intake element 2 is a non-evaporative intake element 2.
[0061] The following examples illustrate this. Example 1
[0062] Figure 1 The image shown is one embodiment of this utility model. In this embodiment, a needle-shaped non-evaporative suction element 2 is provided in the vacuum space of the vacuum glass, located near the sealing edge 2 on the left side. The cross-sectional shape of the suction element 2 is as follows: Figure 3 As shown, its maximum inner diameter is 2 mm. The active intake part 6 of the intake element 2 is wrapped by the protective layer 7, isolating it from the air before activation. The needle-shaped non-evaporative intake element 2 has a circular or elliptical cross-sectional shape with an opening on one side. During activation, residual gas enters the intake element 2 through this opening and is adsorbed. The groove structure 5 is a supporting structure for the intake element 2. The groove structure 5 is located near the sealing edge 2 of the vacuum glass, and its cross-sectional shape is as shown. Figure 2 As shown. Figure 2 The groove structure 5 shown has a U-shaped cross-section. The groove on the glass component 1 is a slender needle channel structure that is adapted to the needle-shaped suction component 2. It is set on the lower glass component 1. During the normal installation and use of vacuum glass, it can be hidden in the protective edging or frame along with the sealing edge 2 without the need for separate shielding. This increases the effective usable area of the vacuum glass, ensures the overall light transmittance of the vacuum glass, and results in a high-quality vacuum glass product. Example 2

In this embodiment, a needle-shaped non-evaporative suction element 2 is provided in the vacuum space of the vacuum glass, located near the left sealing edge 2. The cross-sectional shape of the suction element 2 is as follows: Figure 6 As shown, its maximum inner diameter is 2 mm. The active intake part 6 of the intake element 2 is wrapped by the protective layer 7, isolating it from the air before activation. The needle-shaped non-evaporative intake element 2 has a rectangular cross-sectional shape with an opening on one side. During activation, residual gas enters the intake element 2 through this opening and is adsorbed. The groove structure 5 is adapted to the intake element 2. The groove structure 5 is located near the sealing edge 2 of the vacuum glass, and its cross-sectional shape is as follows. Figure 5 As shown. Figure 5 The groove structure 5 shown has a U-shaped cross-section. The groove on the glass component 1 is a slender needle channel structure that is adapted to the needle-shaped suction component 2. It is set on the lower glass component 1. During the normal installation and use of the vacuum glass, it can be hidden in the protective edging or frame along with the sealing edge 2 without the need for separate shielding. This increases the effective usable area of the vacuum glass, ensures the overall light transmittance of the vacuum glass, and results in a high-quality vacuum glass product. Example 3
[0064] Figure 7 The image shown is one embodiment of this utility model. In this embodiment, a needle-shaped non-evaporative suction element 2 is provided in the vacuum space of the vacuum glass, located near the left sealing edge 2. The cross-sectional shape of the suction element 2 is as follows: Figure 9 As shown, its maximum inner diameter is 2 mm. The active intake part 6 of the intake element 2 is wrapped by the protective layer 7, isolating it from the air before activation. The needle-shaped non-evaporative intake element 2 has a triangular cross-sectional shape with an opening on one side. During activation, residual gas enters the intake element 2 through this opening and is adsorbed. The groove structure 5 is adapted to the intake element 2. The groove structure 5 is located near the sealing edge 2 of the vacuum glass, and its cross-sectional shape is as shown. Figure 8 As shown. Figure 8 The groove structure 5 shown has a U-shaped cross-section. The groove on the glass component 1 is a slender needle channel structure that is adapted to the needle-shaped suction component 2.
