Frequently Asked Questions
- What does this utility model patent protect?
-
This patent protects the specific structural design of a rotary air hose connection mechanism used in inflation pumps. It covers the novel arrangement that allows the air hose to rotate freely at its connection point to the pump body, preventing tangling and reducing mechanical wear. The protection is held by Monzhen Technology (Shenzhen) Co., Ltd. under Patent No. ZL 2025 2 0900699.0.
- How long is this patent valid, and who maintains it?
-
Under Chinese patent law, utility model patents are valid for 10 years from the filing date. This patent was filed on May 9, 2025, giving it protection until approximately May 9, 2035, provided annual maintenance fees are paid on schedule. The patent holder, Monzhen Technology (Shenzhen) Co., Ltd., is responsible for maintaining the patent. Current validity status can be confirmed via the CNIPA Patent Register.
- What is the difference between a utility model patent and an invention patent in China?
-
In China’s patent system, an invention patent requires substantive examination and is valid for 20 years, while a utility model patent (实用新型) undergoes only formal examination and is valid for 10 years. Utility model patents are typically granted faster and cover structural or shape-based innovations, making them well suited for mechanical components like this rotary hose connection mechanism.
- How does this patented mechanism benefit users of the 龙德 inflation pump?
-
The rotary connection mechanism allows the air hose to rotate 360 degrees at the pump interface, eliminating hose kinking and tangling during use. This extends hose lifespan, improves user comfort during extended inflation tasks, and reduces the risk of connection failure under repeated mechanical stress — all of which contribute to the overall reliability and durability of the 龙德 product line.
