2results about How to "Efficient and quick removal" patented technology

Provided are a material removal device and method for a battery electrode plate, to remove a coating material of a predetermined region of the battery electrode plate. The battery electrode plate includes a current collector and a coating material attached to a surface of the current collector. The material removal device for a battery electrode plate includes a positioning member, a spraying port, and a suction port. The positioning member includes a side plate. A hollow space is defined by the side plate. The side plate is configured to be in contact with the current collector to isolate the coating material of the predetermined region in the hollow space. The spraying port is located in the hollow space, and configured to be in communication with a liquid source to spray a liquid onto the coating material of the predetermined region. The suction port is located in the hollow space and configured to be in communication with a vacuum generation device to suck the coating material of the predetermined region away from the current collector.

The utility model relates to a kind of net taste device and refrigerator.Net taste device includes: photocatalysis module, including carrier and photocatalyst, the carrier is configured as adsorbing odor molecule, the photocatalyst is arranged on the surface of the carrier;And light source, configured as providing excitation light irradiated on the photocatalysis module, for exciting the photocatalyst.Wherein, carrier utilizes the adsorption of odor molecule using "van der waals force", that is, using adsorption method to adsorb odor gas, this method can quickly and efficiently deodorization even in low temperature environment;And by light source provides excitation light irradiated on photocatalysis module, for exciting photocatalyst, so that photocatalyst is excited to produce active substance, the active substance and odor molecule occur catalytic decomposition reaction, to realize continuous and efficient removal of odor, even in low temperature condition, reaction efficiency is also higher.
