Description

Technical Field

[0001] This utility model relates to the field of getter container technology, and more specifically, to a getter container for vacuum insulation panels. Background Technology

[0002] Vacuum insulation panels, as a high-performance insulation material, rely on the near-absolute vacuum environment inside for their core insulation performance. The getter container, as a key auxiliary component of the vacuum insulation panel, is mainly used to hold the getter. The getter actively adsorbs residual gas inside the vacuum insulation panel and gas that has seeped in from the outside, thus maintaining the high vacuum level of the vacuum insulation panel for a long time.

[0003] In the prior art, patent CN204005036U discloses a packaging structure for getter in vacuum insulation panels, including a protective member and a container. The top of the container is open for holding the getter and desiccant; the bottom of the protective member is open, and the top has at least one vent hole. The protective member and the open portion of the container are fastened together, with the protective member mounted on the container and covering the container edge. This invention not only effectively prevents the barrier film of the vacuum insulation panel from being punctured by the container, but also prevents desiccant powder from falling out of the thin container.

[0004] However, the getter encapsulation structure still has the following technical problems: the inside of the getter container is a single cavity structure without partition design. The getter is directly filled in the cavity. During the transportation of the vacuum insulation plate, the getter is prone to accumulation due to vibration, forming local dense areas. In some areas, the adsorption effect will be poor due to the scarcity or absence of getter. Utility Model Content

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0029] like Figures 1-3 , Figure 6As shown in the figure, this utility model embodiment proposes a getter container for vacuum insulation panels, including a box body 1. A box cover 2 is pressed onto the box body 1 by a pressing mechanism 3. The box cover 2 is provided with a plurality of feeding ports 21 and vent holes 22. A first protrusion 24 and a second protrusion 25 are respectively provided at both ends of the box cover 2. A venting mechanism 4 is provided inside the first protrusion 24. The venting mechanism 4 includes a venting membrane 42, which is folded inside the first protrusion 24. A scraper 45 is provided on one side of the venting membrane 42.

[0030] like Figure 1 , Figure 3 , Figure 5 As shown, the box body 1 is provided with several partitions 12, and several discharge cavities 14 for storing getter are formed between the partitions 12 and the inner wall of the box body 1. The upper surface of the box body 1 is provided with strip grooves 13 on both sides.

[0031] Several partitions 12 are arranged in a grid pattern, forming several discharge cavities 14 that allow the getter to be evenly distributed in the box 1, ensuring that the getter in each area can fully contact the gas. The strip groove 13 provides guidance for the unfolding of the breathable membrane 42, ensuring that the breathable membrane 42 unfolds smoothly.

[0032] like Figure 1 , Figure 2 , Figures 6-8 As shown, a handle 23 is fixedly connected to the upper surface of the lid 2, and a U-shaped movable groove 26 is provided on one side of the lid 2. A receiving groove 241 and a card slot 251 are respectively provided in the first protrusion 24 and the second protrusion 25.

[0033] The feeding port 21 is used to add getter into the discharge chamber 14. Then, the getter is sealed in the discharge chamber 14 by unfolding the venting membrane 42. Several vent holes 22 serve as gas exchange channels, allowing residual or infiltrated gas inside the vacuum insulation board to enter the box 1 and contact the getter. The receiving groove 241 and the slot 251 are used to receive the venting mechanism 4 in the initial state and the fixed venting membrane 42 after unfolding.

[0034] like Figures 2-4 , Figure 6 , Figure 9 As shown, the ventilation mechanism 4 also includes a fixed plate 41, which is fixedly connected to the receiving groove 241. One end of the ventilation membrane 42 is fixedly connected to the fixed plate 41, and the other end is fixedly connected to a movable plate 43. A scraper 45 is fixedly connected to the lower surface of the movable plate 43. An operating rod 44 is fixedly connected to one end of the movable plate 43 near the U-shaped movable groove 26. The operating rod 44 passes through one side of the box cover 2 and is slidably connected to the inner wall of the U-shaped movable groove 26. Guide blocks 46 are fixedly connected to the lower surfaces of both ends of the fixed plate 41 and the movable plate 43. The guide blocks 46 are slidably connected to the inner wall of the strip groove 13.

[0035] Before adding the getter, the breathable membrane 42 is folded and positioned between the fixed plate 41 and the movable plate 43. The fixed plate 41, the breathable membrane 42, and the movable plate 43 are all located in the receiving groove 241. After adding the getter, the extended operating rod 44 drives the internal movable plate 43 to move towards the second protrusion 25, causing the breathable membrane 42 to gradually unfold and cover the discharge chamber 14. Subsequently, the box cover 2 is pressed to fix the getter in the discharge chamber 14. The guide block 46 slides along the inner wall of the strip groove 13 to provide precise guidance for the movement of the movable plate 43 and prevent the movable plate 43 from tilting.

[0036] As the scraper 45 moves with the movable plate 43, it flattens the accumulated getter, ensuring that the getter is evenly distributed in the discharge chamber 14.

[0037] like Figure 1 , Figure 2 As shown, the clamping mechanism 3 includes a pressure plate 31 fixedly connected to both ends of the first protrusion 24 and the second protrusion 25 respectively. Mounting plates 11 are fixedly connected to both ends of the box body 1. Several guide rods 32 are provided through the pressure plate 31. The lower end of the guide rod 32 is fixedly connected to the mounting plate 11. A spring 33 is fixedly installed on the upper end of the guide rod 32. The spring 33 is sleeved on the body of the guide rod 32. The lower end of the spring 33 is fixedly connected to the upper surface of the pressure plate 31.

[0038] In the initial state, the lid 2 presses against the box body 1 under the elastic force of the spring 33. When it is necessary to unfold the breathable membrane 42, the lid 2 is moved upward by pulling the handle 23, the spring 33 contracts, and the breathable mechanism 4 is disengaged from the receiving groove 241 for easy movement. When the operating rod 44 moves to the other end of the U-shaped movable groove 26, the lid 2 is lowered, so that the movable plate 43 is inserted into the slot 251. At the same time, the lid 2 presses against the breathable membrane 42, thereby fixing the breathable membrane 42.

[0039] This setup allows for rapid loading of the getter, preventing it from shifting randomly and improving the uniformity of gas adsorption in different areas.

[0040] The working principle of a getter container for a vacuum insulation panel:

[0041] Add getter into the discharge chamber 14 through several discharge ports. Pull up the handle 23 to move the lid 2 upwards. The spring 33 contracts, causing the venting mechanism 4 to disengage from the receiving groove 241. Move the operating rod 44 from one end of the U-shaped movable groove 26 to the other end, causing the movable plate 43 to move synchronously. The venting membrane 42 gradually unfolds, and the scraper 45 flattens and spreads the accumulated getter evenly. When the operating rod 44 moves to the other end of the U-shaped movable groove 26, lower the lid 2, causing the movable plate 43 to engage in the slot 251. Under the elastic force of the spring 33, the lid 2 presses the venting membrane 42 tightly, thus pressing the venting membrane 42 onto the getter, preventing the getter from moving randomly and improving the uniformity of gas adsorption in each area.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
