Description

Technical Field

[0001] This utility model relates to the field of vacuum glass, specifically to a vacuum glass air intake structure. Background Technology

[0002] Vacuum glass is generally made up of two or more panes of glass. By sealing the two panes of glass and removing the air in between, a vacuum layer is formed. Vacuum glass has excellent thermal insulation and sound insulation properties.

[0003] Air may remain inside the vacuum chamber of vacuum glass, or trace amounts of gas may be slowly released by the material over time, causing a decrease in the vacuum level inside the chamber. Therefore, vacuum glass typically contains a getter to maintain the vacuum level inside the chamber over a long period, thereby extending its service life. However, most vacuum glass on the market uses round getters, which are far from the edge of the glass. This results in one or more obvious round dots on the frames of home decoration, curtain walls, and electrical appliance glass panels. Due to the volume and placement of the getter, the position of the getter is much larger than the depth of the groove into which the glass is installed, so it cannot be concealed during installation, affecting the aesthetics of the glass. Utility Model Content

[0004] To address the appearance issues caused by the aforementioned built-in getter in the cavity, this invention provides a vacuum glass getter structure, comprising a vacuum glass and a getter unit. The vacuum glass consists of two glass plates of equal size, with a sealing layer around the edges of the two glass plates to form a cavity. The getter unit is cylindrical, with evenly distributed air holes on its side. The getter unit is located within the cavity and is parallel to the edge of the vacuum glass. The distance between the getter unit and the sealing layer is 4 mm, and the diameter of the getter unit is 1 mm.

[0005] The intake unit 3 contains an intake agent.

[0006] The inner side of the glass plate 1 is provided with a fixing groove corresponding to the size of the air intake unit, and the depth of the fixing groove is ≤1mm. The air intake unit is made of a rolled metal sheet and contains an air intake agent.

[0007] The air intake unit can be in the shape of a C-shaped or U-shaped tube.

[0008] The beneficial effects of this utility model are:

[0009] The suction unit of this utility model is installed in a shallow groove of less than 1 mm and close to the edge of the glass. Compared with the traditional form of suction agent, this utility model has a small size and the suction unit is fixed at a position less than the depth of the groove in the glass. During subsequent installation, the suction unit can be completely hidden in the fixed frame and cannot be seen with the naked eye, thus improving the overall aesthetic effect of the vacuum glass.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] In the description of this utility model, it should be noted that the terms "inner," "upper," "lower," "left," and "right," etc., indicate the orientation or positional relationship based on the positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] Please refer to Figures 1-4 A vacuum glass suction structure includes a vacuum glass 1 and a suction unit 3. The vacuum glass is composed of two glass plates 1 of equal size, and the edges of the two glass plates 1 are sealed with a sealing layer 2 to form a cavity. The suction unit 3 is cylindrical (e.g., ...). Figure 2 , 4 As shown), the air intake unit 3 has evenly distributed air holes 31 on its side. The air intake unit 3 is located in the cavity. The air intake unit 3 is arranged parallel to the edge of the glass plate 1. The distance between the air intake unit and the sealing layer is 4mm.

[0018] The suction unit 3 contains a suction agent. The air holes can be arranged in one or more rows evenly on the surface of the suction unit 3. The shape of the air holes can be round, square or other shapes. The diameter of the suction unit is 1 mm.

[0019] A fixing groove is provided on the inner side of the glass plate 1 corresponding to the size of the air intake unit 3. The fixing groove is 14mm away from the edge of the glass plate 1. The air intake unit 3 is located in the fixing groove. The air intake unit 3 is made of a metal sheet rolled up. Before rolling, holes are punched to form a thin metal tube, and an air intake agent is placed inside the tube.

[0020] The specific suction unit 3 can be C-shaped or U-shaped, with a metal sheet directly pressed into the fixed groove to form a C-shaped or U-shaped tube. The suction agent is then placed inside the tube to simplify processing requirements. If it is C-shaped or U-shaped, a certain suction groove is formed, and drilling is no longer required. These two structures are not shown in the figure.

[0021] The vacuum glass manufacturing method based on the above-mentioned air-suction structure includes the following:

[0022] S1: Cutting. According to the design dimensions, the 6mm thick glass sheet is cut into two glass plates 1 of the same size. After cutting, a fixing groove with a depth of ≤1mm is processed on one of the glass plates 1 at a distance of 14mm from the edge. Finally, the cut glass plate 1 is ground, cleaned and dried to remove burrs, oil stains, dust and other impurities to ensure the fit between the two glass plates 1.

[0023] S2: Applying adhesive and placing supports. The glass plate 1 cut in step S1 needs to be tempered at high temperature. After processing, sealant is applied to the edges of the two glass plates 1. The sealant is glass powder or metal powder. The glass plate 1 with the fixed groove is placed below. Then, the suction unit 3 is placed in the fixed groove of the glass plate 1 below. Supports 4 are also evenly placed on its surface. The supports 4 maintain the gap between the two glass plates 1. The sealant surrounds the edges of the glass plate 1 to form a cavity. The supports 4 are metal, ceramic or glass microspheres to prevent the glass plate 1 from being pressed and dented by atmospheric pressure. No specific restrictions are made here.

[0024] The length of the suction unit in this embodiment is selected according to the size of the cavity formed between the two glass plates 1. At the same time, there can be multiple fixing slots, and fixing slots can be opened on one or both sides or above of the glass plates 1.

[0025] S3: Sealing and Joining. The arranged glass plates 1 are fed into the vacuum device, which is a high-temperature adjustable vacuum sealing device. A vacuum environment is created within the device using a vacuum pump, and the sealing material is heated and melted using a brazing process. After cooling, the sealing material forms a sealing layer 2, which connects and fixes the upper and lower glass plates 1 together to form a single piece of glass. Simultaneously, the vacuum cavity between the two plates is sealed, forming a vacuum glass. This achieves integrated vacuuming and sealing. The width of the sealing layer 2 after cooling is 10mm, and the distance between the suction unit 3 and the sealing layer is 4mm. The getter in the suction unit 3 is activated at a specific high temperature. After the two glass plates 1 are joined, the getter is activated, and any residual air or slowly released gas in the cavity reacts with the getter through the vent 31, thus maintaining the vacuum level within the vacuum cavity.

[0026] The vacuum sealing device is existing technology and will not be described in detail here.

[0027] S4: Inspection and Packaging. Perform visual inspection, vacuum degree testing, pressure resistance and sealing performance tests on the vacuum glass to ensure that the product meets the standards before packaging and boxing.

[0028] like Figure 3 , 4 As shown, after the vacuum glass is installed, the fixed position of the suction unit is smaller than the depth of the glass groove. The suction unit 3 is hidden inside the fixed frame 5 and cannot be observed with the naked eye, which improves the overall aesthetic effect of the vacuum glass.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
