[0039] The bottom plate 2 is a key component for connecting the cover 1, and its main function is to seal the containing space 1a, thereby maintaining the stability of the environment inside the cover 1. In actual application, the bottom plate 2 and the cover 1 can be sealed by welding, bolt fastening or other means.

[0040] Further, at least one external pipe port 3 is arranged on the bottom plate 2. The external pipe port 3 is in communication with the inside of the containing space 1a, allowing the airflow to flow freely in multiple directions - either from the inside of the cover 1 to the outside of the bottom plate 2 (such as the exhaust process), or introducing gas from the outside of the bottom plate 2 to the inside of the cover 1 (such as the intake or air exchange process). In actual application, the number and position of the external pipe port 3 can be reasonably arranged according to actual needs to optimize the efficiency and uniformity of gas flow.

[0041] In the present embodiment, as shown in the accompanying Figure 2 , the bottom plate 2 is a flat plate structure, which is convenient for production and installation, connection with the cover 1, and ensures the stability and durability of the whole device. And in the production process, the flat plate structure of the bottom plate 2 eliminates welding and secondary finishing, shortens the production cycle, reduces the production cost, increases the use intensity of the whole device, improves the durability of the device, at the same time ensures the smoothness of gas flow, reduces vortex and resistance, and improves the user experience.

[0042] In one embodiment, at least one connecting part 4 is arranged on the bottom plate 2 away from the cover 1 to connect with an external support assembly, which enhances the stability and load-bearing capacity of the whole bell-shaped device.

[0043] In actual application, as shown in the attached Figure 2 figure, the connecting part 4 of the embodiment is a plurality of blind holes arranged on the bottom of the bottom plate 2, which are distributed on the edge or central area of the bottom plate 2 to ensure the stability and balance of the bell-shaped device after installation. The whole device is connected with external support rods through the blind holes to maintain the stability of the bell-shaped device. Specifically, the size and shape of the blind holes can be adjusted according to actual needs or the type and size of the support rods.

The sealing assembly 5 is arranged at the connection between the bottom plate 2 and the cover 1 and is press-fitted with the connection between the bottom plate 2 and the cover 1. When the cover 1 is combined with the bottom plate 2, the sealing assembly 5 effectively fills and seals the small gap between them, thereby ensuring the sealing of the accommodation space 1a. In actual application, the sealing assembly 5 can include a series of annular or strip-shaped sealing strips, sealing pads or sealing films, in addition, the sealing assembly 5 can also be equipped with a special pressing mechanism or adjusting device to fine-tune it when needed to ensure the best sealing effect.

[0047] As shown in the attached Figure 4 figure, the sealing assembly 5 is a sealing ring 6, in order to ensure the reliability and durability of the sealing, the inner side of the sealing ring 6 is provided with a first concave-convex structure 7, which increases the physical contact area between the sealing ring 6 and the contact surface, and also effectively improves the tightness and stability of the sealing through the interaction of the concave-convex structures.

[0048] The outer edge of the bottom plate 2 and the cover body 1 is provided with a second concave-convex structure 8 matched with the first concave-convex structure 7. When the cover body 1 is combined with the bottom plate 2, the sealing ring 6 is clamped between the two, and the first concave-convex structure 7 on the inner side is tightly pressed with the second concave-convex structure 8 on the outer edge of the bottom plate 2 and the cover body 1, which ensures the tightness of the seal, and also effectively prevents the sealing ring 6 from loosening or shifting during long-term use through the mutual embedding of the concave-convex structures. In actual application, in order to achieve the best sealing effect, the sealing ring 6, the first concave-convex structure 7 and the second concave-convex structure 8 are usually made of high molecular materials with excellent elasticity, wear resistance and aging resistance, to ensure stable sealing performance under extreme conditions.

[0049] In one specific embodiment, a temperature control assembly is also included, which is arranged in the cover body 1 for adjusting the temperature in the containing space 1a, improving the functionality and flexibility of the bell jar device, and providing strong support for various experiments, tests or production processes that require specific temperature environments.

[0053] In one specific embodiment, the gas flow direction of the external pipe port 3 is consistent with the extension direction of the central axis of the cover body 1. The external pipe port 3 serves as the key interface for the bell jar device to exchange gas with the external environment, and the setting of the gas flow direction is crucial to ensure the stability and uniformity of the environment in the cover body. In this embodiment, the gas flow direction of the external pipe port 3 is kept in line with the central axis of the cover body 1, which not only optimizes the gas flow path, reduces unnecessary turbulence and vortex, but also ensures that the gas can be uniformly and efficiently distributed into the containing space 1a, increasing the overall use intensity of the device, improving the durability of the device and enhancing the user experience.

[0054] In one specific embodiment, the cover body 1 is also provided with a connection assembly 9 at the end away from the base plate 2 for connecting external devices.

It improves the integration capability and flexibility of the bell jar device, and also provides a more efficient, reliable and convenient solution for various complex and variable application scenarios.

[0055] In one specific embodiment, the connecting part 4 includes a blind hole 10 matched with the shape of the external support assembly, and the base plate 2 is connected with the external support assembly through the blind hole 10.
