Recently, the State Intellectual Property Office officially issued an authorization notice. The invention patent "A two-in-one quick connector with liquid extraction and air intake functions" (CN119508538 B) independently developed by Baoshili (Shanghai) New Materials Technology Co., Ltd. has been successfully authorized on April 25, 2025. This is another important achievement of Baoshili (Shanghai) in the invention of ultra-pure chemical packaging materials.
In the field of ultra-pure chemical packaging and transmission, the existing two-in-one connectors with liquid extraction and air intake functions have the following technical problems:
01 Sealing problem
The sealing design of the multifunctional connector is complex. Since it needs to have both liquid extraction and air intake functions, if the sealing design is not precise enough, it is easy to cause air or liquid leakage, which in turn affects the efficiency and safety of the system.
02 Corrosion resistance and wear resistance
When it comes to the transmission of different fluids (such as liquids and gases), the material of the connector must have good corrosion resistance, wear resistance and high pressure resistance. Otherwise, as the use time increases, the connector may corrode, wear or age, resulting in performance degradation or failure.
03 Complex operation issues
For connectors that need to have both the functions of pumping and air intake, if the two fluids are manually replaced, the working efficiency of the connector will be affected. If corrosive fluids are passed, manual replacement will also cause harm to human health.
"A two-in-one quick connector with pumping and air intake functions" developed by Baoshili has successfully overcome the above difficulties. It has three major advantages:
01 Convenient and efficient operation
Integrated pumping and air intake functions, simplified installation and use, automatic switching operation, saving a lot of manpower and time costs, and greatly improving work efficiency.
02 Eliminate reflux pollution
The clever design prevents liquid reflux, effectively avoids cross contamination, ensures the purity and safety of chemicals, and provides strong guarantees for high-precision processes.
03 Excellent and reliable performance
Excellent sealing and stability, can withstand a certain pressure and flow, and is not afraid of high pressure and complex working conditions, escorting the entire process of chemical transportation and storage.
At present, the invention is applied to Baoshili's ultra-pure chemical packaging materials, that is, Ultra-Clean HDPE Drum, which integrate the connection equipment of liquid extraction and gas delivery functions and are widely used in liquid delivery or extraction systems, such as chemical processing, fluid control systems, mechanical equipment, laboratory instruments, etc.
Baoshili's Ultra-Clean HDPE Drum have a leading advantage in the industry. They are made of imported high-purity HDPE raw materials and hollow blow molding equipment. They have ultra-clean, low particle, low ion precipitation, chemical resistance and other characteristics. They meet SEMI standards and are suitable for the storage and transportation of electronic-grade chemicals in the semiconductor and microelectronics fields.
Through continuous deep cultivation in the fields of chemical packaging and cleaning materials, Baoshili has accumulated more than 70 patents, covering three major categories: ultra-pure fluorine material products, ultra-pure chemical packaging materials, and Cleanroom Wiper. Among them, ultra-pure fluorine materials and ultra-pure chemical packaging materials, as the core of Baoshili's localization substitution strategy, are relying on their independent research and development advantages to continuously break the foreign technology monopoly and inject strong momentum into the development of the industry.
