Company patents

SHENZHEN JISU TECHNOLOGY CO., LTD

SHENZHEN JISU TECHNOLOGY CO., LTD's patent strategy reveals a surprising dual focus, with over half (53.7%) of its portfolio in Pumps (Centrifugal) and a significant 25.6% in Implants & Prosthetics, suggesting a diversification beyond traditional manufacturing into medical devices. While Pumps (Centrifugal) saw a 100.0% growth in 2025, its 25.0% decline so far in 2026, alongside a 75.0% decline in Implants & Prosthetics for 2026, indicates a potential shift in priorities, even as Electric Motors & Generators emerges as a new focus with a 100.0% growth in 2026 (so far).

Portable fan

Filed:2025-06-11Pub:2026-04-14
Applicant:SHENZHEN JISU TECHNOLOGY CO., LTD

A schematic diagram of a portable fan of the present disclosure is shown. The portable fan includes a housing, a substrate, and a fan assembly. The housing includes an accommodating cavity. The housing is further formed with an air inlet communicated to the accommodating cavity. At least a portion of the substrate is arranged on a radial inner side of the housing, and an air outlet is formed between the substrate and the housing. The fan assembly is arranged inside the accommodating cavity and is connected to a rear side of the substrate. The fan assembly includes a motor and a fan blade. The motor is a high-speed motor. A maximum diameter of the substrate is greater than or equal to a maximum diameter of the fan assembly, a front side of the substrate includes a protrusion. The protrusion protrudes forwards out of a front end of the housing.

FAN BLADE AND FAN

Filed:2025-09-19Pub:2026-01-15
Applicant:SHENZHEN JISU TECHNOLOGY CO., LTD

A fan blade and a fan are provided. The fan blade includes a hub and a plurality of blades. Each blade includes a blade root and a blade tail. The blade tail is twisted relative to the blade root. The blade roots of the plurality of blades are connected to the hub. By twisting the blade tail relative to the blade root, a twisted part plays a role in converging incoming air, so that air blown out of the fan blade is more concentrated, an air blowing effect is enhanced, and a user experience is enhanced. The twisted part plays the role in converging the incoming air, so that the air blown out of the fan blade is more concentrated, which increases an axial pressure, forms an air flow, improves air flowing efficiency of the blades, and improves a wind effect.

PORTABLE FAN

Filed:2024-03-26Pub:2024-07-11
Applicant:SHENZHEN JISU TECHNOLOGY CO.,LTD

A portable bladeless fan is provided and includes: a housing, a mix-flow fan, and a pressurizing member. The housing has an air inlet portion at a rear side of the housing and an air outlet portion at a front side of the housing. The mix-flow fan is configured to generate an airflow. The pressurizing member is connected to a front portion of the housing and disposed at a front of the mix-flow fan. The pressurizing member includes a pressurizing seat and second blades. The pressurizing seat includes a pressurizing surface that is at least partially increased in a radial direction from the rear side to the front side, the second blades are spaced apart from each other and are arranged on the pressurizing surface. The second blades re-arrange a direction of the airflow and to reduce a noise of the airflow.
