Description

Technical Field

[0001] This utility model relates to the field of honeycomb glass manufacturing technology, specifically a honeycomb-shaped glass. Background Technology

[0002] Honeycomb structures, as a highly efficient porous functional material, are widely used in gas separation, liquid filtration, catalytic reactions, and heat exchange. Traditional honeycomb structures are usually made of ceramic, metal, or polymer materials, and their internal channels are often irregularly arranged, making internal size control difficult and prone to dust generation. Although they possess a certain airflow or liquid conduction capacity, they still have significant limitations in practical applications. For example, the irregular channel design easily leads to turbulent airflow discharge, making it difficult to control airflow and pressure. In addition, the liquid storage function of traditional honeycomb structures is generally weak, and the liquid is prone to uneven distribution within the channels, making it difficult to achieve a balance between dynamic regulation and stable storage. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a honeycomb-shaped glass, which solves the technical problems that honeycomb structures cannot lock liquid and control airflow.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a honeycomb-shaped glass, comprising: A glass substrate having a first end face and a second end face opposite to each other, with a plurality of honeycomb microporous units provided between the first end face and the second end face. The honeycomb microporous units include inlet holes and outlet holes located on the first end face and the second end face respectively, and the inlet holes and outlet holes are connected by a guide channel. The guide channel is provided with multiple liquid storage unit cavities spaced vertically, and adjacent liquid storage unit cavities are connected by multiple horizontally arranged airflow unit channels.

[0005] Preferably, the guide channel is arranged in a vertical straight line.

[0006] Preferably, the inner diameter of the liquid storage unit cavity is larger than the inner diameter of the airflow unit channel.

[0007] Preferably, the cross-section of the liquid storage unit cavity is elliptical.

[0008] Preferably, the inner diameter of the liquid storage unit cavity is in the range of 45-60µm.

[0009] Preferably, the inner diameter of the airflow unit channel is in the range of 25-40µm.

[0010] Preferably, the glass substrate is transparent.

[0011] Preferably, semiconductor processes are used to achieve micron-level precision in the cellular aperture.

[0012] By employing the above technical solution, this utility model provides a honeycomb-shaped glass, which has at least the following beneficial effects: 1. This honeycomb glass, by setting straight guide channels within the glass substrate and arranging liquid storage unit cavities at intervals along the vertical direction, while connecting airflow unit channels between adjacent liquid storage unit cavities laterally, forms a composite structure for gas-liquid regulation. The straight guide channel design adjusts the airflow transmission path within the glass substrate, and in conjunction with the liquid storage unit cavities' function of storing liquid, the perforations effectively slow down the airflow discharge speed, achieving precise control of airflow pressure. The connection structure between the liquid storage unit cavities and the airflow unit channels not only utilizes liquid surface tension to balance gravity and prevent rapid liquid loss, but also achieves dynamic release and storage balance of liquid through air pressure conduction via the airflow unit channels, solving the problems of weak liquid storage function and insufficient airflow regulation capability in traditional honeycomb structures.

[0013] 2. In this honeycomb glass, the airflow from the gas source enters the straight guide channel through the inlet hole. Under the synergistic effect of the liquid storage unit cavity and the airflow unit channel, the air pressure is gradually adjusted due to the extension of the airflow path, liquid damping, and changes in the inner diameter of the channel. When the airflow passes through the liquid storage unit cavity, the presence of liquid increases the airflow resistance, forming a pressure buffer. The horizontally connected airflow unit channel can balance the air pressure difference between each liquid storage unit cavity, making the overall air pressure output more uniform and stable. This structure not only solves the problems of complex structure and low control accuracy of traditional air pressure control devices, but also allows for direct observation of the internal gas-liquid flow state due to the transparency of the glass substrate, facilitating real-time monitoring and adjustment. It has broad application prospects in fields such as microfluidic control. Attached Figure Description

[0016] 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.

[0017] Microfluidic control technology is playing an increasingly important role in fields such as biomedicine and chemical analysis. This requires glass materials capable of precisely manipulating tiny droplets, including functions such as storage, flow guidance, and controlled release. However, existing glass materials cannot adequately meet these requirements, necessitating the development of novel glass structures.

[0018] Due to the inherent limitations of existing technologies, such as the inability of honeycomb structures to store liquid and control airflow, please refer to... Figures 1-3 The honeycomb-shaped glass provided in this embodiment can realize the dynamic release and storage balance of liquid, and solve the problems of weak liquid storage function and insufficient airflow control capability of traditional honeycomb structures.

[0019] Traditional honeycomb structures typically have straight internal channels, allowing for rapid airflow and hindering pressure regulation. Furthermore, liquids tend to leak quickly through these straight channels, resulting in poor liquid storage. To address this issue, the glass substrate 1 has a first end face 11 and a second end face 12. Multiple honeycomb microporous units are positioned between the first end face 11 and the second end face 12. Each honeycomb microporous unit includes an inlet hole 111 and an outlet hole 121 located on the first end face 11 and the second end face 12, respectively. The inlet hole 111 and the outlet hole 121 are connected by a guide channel 13. The inlet hole 111 and the outlet hole 121... The connection design with the guide channel 13 establishes the basic path for gas-liquid transmission, providing a structural carrier for subsequent liquid storage and pressure regulation. Furthermore, multiple liquid storage unit cavities 14 are arranged vertically at intervals within the guide channel 13, and adjacent liquid storage unit cavities 14 are connected by multiple horizontally arranged airflow unit channels 15. The liquid storage unit cavities 14 can utilize the surface tension of the liquid to balance gravity, achieving leakage-free storage and solving the problem of rapid liquid loss. Moreover, the airflow unit channels 15 connect adjacent liquid storage unit cavities 14, balancing the pressure difference and forming an airflow guiding network to achieve coordinated pressure regulation.

[0020] Traditional straight channel designs result in short airflow transmission paths and rapid air pressure release, making it impossible to effectively regulate air pressure. To address this issue, the guide channel 13 is designed in a wavy, curved shape. The wavy, curved channel extends the airflow transmission path within the glass substrate 1, increases airflow resistance, slows down the discharge speed, and achieves precise regulation and buffering of air pressure.

[0021] Traditional honeycomb structures have uniform inner diameters, making it impossible to create differentiated functions for liquid storage and airflow conduction, resulting in low gas-liquid interaction efficiency. To address this issue, the inner diameter of the liquid storage unit cavity 14 is larger than that of the airflow unit channel 15. The larger inner diameter of the liquid storage unit cavity 14 provides ample liquid storage space, enhancing liquid storage capacity. The smaller inner diameter of the airflow unit channel 15 restricts liquid flow while ensuring smooth airflow conduction, achieving gas-liquid separation and coordinated control.

[0022] Traditional circular liquid storage chamber structures have low utilization efficiency of liquid surface tension, insufficient liquid storage stability, and uneven resistance distribution when airflow passes through. To address this issue, the cross-section of the liquid storage unit chamber 14 is elliptical. The elliptical cross-section can optimize the distribution of liquid surface tension and enhance the stability of liquid storage. At the same time, the major axis of the elliptical structure can guide airflow, reduce resistance, and improve gas-liquid interaction efficiency.

[0023] Traditional honeycomb structure channels lack precise design, resulting in either excessively large pores leading to liquid loss or excessively small pores affecting airflow conduction, failing to simultaneously achieve liquid storage and air pressure regulation functions. To address this issue, the inner diameter of the liquid storage unit cavity 14 ranges from 45 to 60 µm; the inner diameter of the airflow unit channel 15 ranges from 25 to 40 µm. The micron-level inner diameter of the liquid storage unit cavity 14 can balance the liquid's gravity and surface tension, achieving leak-free storage; the micron-level inner diameter of the airflow unit channel 15 can ensure smooth airflow and also create air pressure damping through the pore size difference, assisting in air pressure regulation.

[0024] Traditional honeycomb structures often use opaque materials such as ceramics and metals, which make it impossible to directly observe the internal gas-liquid flow state and are not convenient for real-time monitoring and control. To address this issue, the glass substrate 1 is transparent. The transparent glass substrate 1 allows for direct observation of the gas-liquid flow in the internal liquid storage unit cavity 14 and airflow unit channel 15 through optical means, facilitating real-time monitoring of the gas pressure control process and improving the controllability and reliability of the equipment.
