Description

Technical Field

[0001] This utility model belongs to the field of getters, and specifically relates to a getter container. Background Technology

[0002] A getter is a substance or device specifically designed to adsorb or remove specific impurities from a gas in order to increase or maintain a vacuum level. It is commonly used in environments that require a high vacuum, such as in semiconductor manufacturing, aerospace, optical instruments, electronic equipment, medical devices, and many other high-tech applications.

[0003] Getters work by absorbing gas molecules through chemical reactions or physical adsorption. They can effectively remove impurities such as oxygen, water vapor, carbon dioxide, and carbon monoxide from the air, thereby improving the vacuum level of the system. Getters can be solid materials, such as powder, flakes, tubes, or rings, or they can be in liquid or gas form.

[0004] Existing getter containers, such as the device for maintaining a vacuum in an insulating jacket (authorization publication number CN1046581C), include an open-top container made of an airtight material, preferably aluminum. A first layer of pressure is placed at the bottom of the container, and a second layer of pressure is placed on top to completely cover the first layer. The first layer is made of a Ba-Li getter alloy, while the second layer is made of a powdered desiccant material. The desiccant powder selectively contains a noble metal oxide and a material to prevent desiccant compression. This structure has an open upper surface, which is exposed during transport and storage, allowing the getter to come into contact with external air, thus affecting its performance during use. Utility Model Content

[0005] The main technical problem solved by this utility model is to provide a getter container that can ensure the performance of the getter during use.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a getter container, comprising a container body, wherein the top of the container body is provided with an opening, and a sealing structure is installed at the opening at the top of the container body;

[0007] The encapsulation structure includes a cover structure for covering the opening and a sealing structure for connecting the cover structure to the container body.

[0008] In a preferred embodiment of the present invention, the cover structure includes a circular plate, which is installed at the opening on the top of the container body and matches the shape and size of the opening.

[0009] In a preferred embodiment of the present invention, a circular hole is provided in the center of the circular plate.

[0010] In a preferred embodiment of the present invention, the sealing structure includes a limiting ring and a sealing layer. The limiting ring is installed inside the container body near the opening, and the bottom of the circular plate covers the top of the limiting ring.

[0011] In a preferred embodiment of this utility model, the outer circle of the circular plate is provided with a chamfer, and the chamfer, the limiting ring and the inner wall of the container body form a groove.

[0012] In a preferred embodiment of the present invention, the sealing layer is disposed within the groove.

[0013] The beneficial effects of this utility model are: This utility model provides a getter container, which adopts a sealing structure to seal the top opening of the getter container, thereby preventing the getter from being exposed to the air during storage and transportation, thus ensuring the performance of the getter during use. Attached Figure Description

[0014] Figure 1 This is a sectional view of the front view of a getter container.

[0015] The components in the attached diagram are labeled as follows: 1. Container body; 2. Circular plate; 3. Chamfer; 4. Limiting ring; 5. Circular hole; 6. Sealing layer; 7. Getter. Detailed Implementation

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0017] Please see Figure 1 A getter container includes a container body 1 with an opening at the top. A sealing structure is installed at the opening at the top of the container body 1 to seal the opening at the top of the container body 1, thereby preventing the getter 7 stored in the container body 1 from being exposed to the air during storage and transportation, thus ensuring the performance of the getter 7 when used.

[0018] The encapsulation structure includes a cover structure for covering the opening and a sealing structure for connecting the cover structure to the container body 1.

[0019] The cover structure includes a circular plate 2, which is installed at the opening on the top of the container body 1 and matches the shape and size of the opening.

[0020] The circular plate 2 has a circular hole 5 in the middle. When in use, the circular hole 5 is punctured before use.

[0021] By covering the circular hole 5 with low-temperature glass whose melting temperature is higher than the activation temperature of the getter 7, the getter 7 is first heated to activate it, and then heated until the low-temperature glass melts. After heating, the fluid-like low-temperature glass flows along the circular hole 5, and as the temperature cools down, it blocks the circular hole 5, thereby achieving a sealing effect.

[0022] The sealing structure includes a limiting ring 4 and a sealing layer 6. The limiting ring 4 is installed inside the container body 1 near the opening. The bottom of the circular plate 2 covers the top of the limiting ring 4. The outer circle of the circular plate 2 is provided with a chamfer 3. The chamfer 3 is connected to the limiting ring 4 by welding.

[0023] The chamfer 3, the limiting ring 4, and the inner wall of the container body 1 form a groove, and the sealing layer 6 is disposed in the groove. The sealing layer 6 includes adhesive sealing and heat-melt sealing.

[0024] Unlike existing technologies, this utility model provides a getter container with a sealing structure that seals the top opening of the getter container to prevent the getter from being exposed to air during storage and transportation, thereby ensuring the performance of the getter during use.

[0025] In the description of this utility model, it should be noted that all components are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional test methods. The terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship that the utility model product is usually placed in during use.
