Public-source profile reviewed

Shenzhen Huayi / AISNN

Shenzhen Huayi Transmission Technology Co., Ltd. (SZI Expo listing)

Longgang District, Shenzhen, China (public contact address; site not inspected)

Manufacturing overview

Air-suction devices, paired stimulators and rotating rabbit vibrators.

Shenzhen International Adult Expo identifies Shenzhen Huayi Transmission Technology Co., Ltd. at booth 15.A03 and links its AISNN website. AISNN's own About page names the same company and offers B2B contact at [email protected]. The official catalog supplies distinct product pages for Mango Tango, TornadoX and Rose Duo Symphony. QQip reviewed the product descriptions and images as public supplier sources; legal registry, production premises, audits and model tests remain unverified.

Company and brand connection

SZI Expo lists Shenzhen Huayi Transmission Technology Co., Ltd. and its AISNN domain; the AISNN About page names Shenzhen Huayi as the brand's manufacturer. The expo also publishes a Longgang District contact address. This establishes a public company-to-brand trail but is not an independent visit or registration check.

Three product mechanisms

Mango Tango pairs a suction unit with a connected vibrating unit. TornadoX uses rotating shaft motion with a separate rabbit-ear vibration program. Rose Duo Symphony combines a suction rose and a small connected vibrator, with a cap the supplier describes as switching the rose to tapping. These models should not be treated as interchangeable simply because they share a catalog category.

Published model data and limits

Official product tables provide item numbers or model names, material descriptions, control modes, charging, dimensions and supplier-stated IP ratings. QQip has not received the corresponding material certificates, water-ingress test reports, acoustic test method or sample measurements. Buyers should request documents specific to the exact item and production revision.

Questions for procurement

Confirm the contracting legal entity, precise manufacturing site, sample matching the catalog version, electrical and battery documentation, material declaration, control firmware, package contents, MOQ and lead time. For paired devices, verify how components connect and which parts charge or operate independently.

This profile summarizes the company’s publicly stated activities. Public-source review is separate from an independent factory inspection or ownership claim.
