A portable swimming pool sanitizing dispenser

This application relates to the field of swimming pool disinfection equipment technology, and in particular to a portable swimming pool disinfection dispenser, which includes a feeding assembly, a spraying assembly, a buoyancy device, a drive device, and a direction-changing assembly. The medicine storage tank is equipped with a dosing channel, and the buoyancy device surrounds the medicine storage tank to ensure buoyancy. The spraying assembly uses wind power via a guide vane to rotate the diffusion chamber, achieving uniform dispersion of the disinfectant. This application enhances stability and uniform dispersion of the disinfectant through the design of a rotary bearing, sealing ring, and regulating valve. Simultaneously, the use of wind power to drive the guide vane and rotate the diffusion chamber enables rotation control and convenient operation. This application solves the problems of complexity and high cost of existing equipment, providing a lightweight and economical swimming pool disinfection solution suitable for home and small swimming pool scenarios.

In vitro trans-dermal diffusion apparatus for gas exposure

An in vitro trans-dermal diffusion apparatus for gas exposure, including: a gas generator, an exposure chamber, an exhaust treating device, a sampling arm, a diffusion chamber, a liquid replenishment tank, and a sample bottle rack. The in vitro trans-dermal diffusion apparatus for gas exposure supports multiple diffusion chambers conducting gas exposure experiments simultaneously. The sampling port and replenishing port of the diffusion chamber are separated, enabling the rapid replenishment of fluids through a replenishment tank after sampling, which reduces the time the skin membrane is separated from the receptor fluid. The sampling arm of the in vitro trans-dermal diffusion apparatus for gas exposure, combined with a telescoping rod, allows the sampling needle to be inserted into the sampling port for sampling and can also be extended into a sample bottle to release the sample, minimizing the contact between the sample liquid and the air.
