2results about How to "Improve smoke removal effect" patented technology

This invention belongs to the field of medical device technology, and particularly relates to an endoscopic negative ion smoke removal system and a negative ion smoke removal power control method applied to this system. Compared with the existing technology that uses negative pressure suction to remove smoke from the endoscope lens, this invention provides a novel negative ion smoke removal system, including a base and an endoscope lens. The endoscope lens is mounted at one end of the base, which has an optical interface for providing a light source and a beam guide interface for mounting and transmitting the light source. A negative ion emitting device is located at the observation end of the endoscope lens away from the base. This device receives negative ion input and emits a high-voltage negative ion beam to form a negative pressure electrostatic field in front of the observation end, thereby preventing smoke from adsorbing onto the endoscope's observation surface. The negative ion smoke removal power control method provided by this invention automatically adjusts the negative ion output power through particulate matter detection, achieving a highly efficient and energy-saving smoke removal effect.

This application provides a smoke removal device and a dust removal machine. The smoke removal device includes a housing, a liquefaction module, an electric field module, and a fan. The housing has a receiving cavity and an oil fume inlet. The oil fume inlet is connected to the receiving cavity and is used to allow oil fumes to enter. The oil fumes flow in the receiving cavity and pass through multiple liquefaction components in sequence, so that the oil fumes are liquefied when they come into contact with the liquefaction components, so as to output part of the oil and filtered oil fumes. The electric field module has a honeycomb electric field with a gas channel. The filtered oil fumes are electrolyzed during the flow in the gas channel to output clean gas. The fan is housed in the receiving cavity and draws in the clean gas output by the honeycomb electric field. The exhaust end of the fan is used to discharge the clean gas to the external environment of the housing, so as to facilitate the liquefaction and electrolysis of oil fumes by the liquefaction module and the electric field module, thereby realizing the discharge of clean gas to the external environment, avoiding oil fumes from polluting the external environment, and improving the smoke removal effect of the smoke removal device.
