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.

The utility model discloses an automatic spot welding device for a unit voice coil. The automatic spot welding device comprises an automatic spot welding machine, a protection assembly and an adjusting assembly. According to the automatic spot welding device for the unit voice coil, the smoke protective cover is installed on the lower portion of the spot welding device in the automatic spot welding machine in a sleeved mode, smoke generated in spot welding at the bottom of the spot welding device can be isolated and protected, and the generated smoke is blown to the bottom of the smoke removal pipe on the other side of the smoke protective cover through the micro fan on one side of the smoke protective cover. Therefore, harmful smoke generated during spot welding is sucked into the welding smoke purifier through the smoke removal pipe to be purified, and the problems that the smoke generated during spot welding drifts to the bottom of the visual camera to pollute the visual camera, the detection accuracy of the visual camera is affected, and the safety of workers is affected due to accumulation of the smoke in the external environment are solved. And a bottom protection plate mounted at the bottom of the smoke protection cover below the micro fan can also prevent the problem that the air flow blown by the micro fan blows the spot welding wire harness at the upper end of the voice coil at the lower end.

The utility model discloses a welding machine with a positioning mechanism, which relates to the technical field of welding and comprises a welding platform, supporting seats for supporting are symmetrically mounted at the bottom of the welding platform, a positioning and clamping mechanism is mounted on the top surface of the welding platform, and a welding mechanism is fixedly connected to the rear side of the welding platform. And a smoke removal mechanism is mounted at the top of the welding mechanism. According to the welding machine with the positioning mechanism, the position of the adjusting screw rod in the positioning clamping mechanism is located outside the welding area, so that the phenomenon that adjustment and positioning cannot be achieved in the later period due to slag generated in the bonding welding process is avoided; meanwhile, due to the opposite arrangement of the thread directions on the adjusting screw rods, the movable clamping plates which are symmetrically arranged can be synchronously adjusted in the opposite direction and the reverse direction conveniently, and the convenience of clamping operation of the movable clamping plates on a welded object is improved; and multi-position welding work on the positioned welding object is facilitated.

The utility model belongs to the technical field of kitchen ware manufacturing, and particularly relates to an exhaust fume collecting hood. The smoke collecting hood comprises a box body used for collecting oil smoke, and one end of the box body is connected with a supporting pipeline used for fixing the box body in a penetrating mode. Compared with the prior art, the structure that the supporting pipeline is independently arranged on the box body is adopted. On one hand, the supporting pipeline can play a role of an oil smoke channel; and on the other hand, the supporting pipeline can also fix the box body, so that the box body is arranged above the gas stove. On the basis, the position of the supporting pipeline is specially designed, namely, the supporting pipeline is arranged at one end of the box body, so that the kitchen occupied space of the exhaust fume collecting hood is greatly reduced, and correspondingly, the cookware operation space is larger. Besides, compared with the folding design of the exhaust fume collecting hood in the prior art, the box body of the exhaust fume collecting hood can be directly arranged right above the burner of the gas stove, so that the oil fume suction is more accurate, and the fume purification effect is better.

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.
