Adhesive composition for all-solid-state batteries, electrode sheets and all-solid-state batteries
This application relates to the field of all-solid-state lithium battery technology, disclosing an adhesive composition, electrode sheet, and all-solid-state battery for all-solid-state batteries. The composition includes 0.5-5.0 parts of a modified polymer adhesive and 95.0-99.5 parts of a non-polar organic solvent. The modified polymer has a hydrocarbon backbone and side chains containing 0.5-15.0 mol% nitrile or ester groups. The electrode sheet of this invention contains only 0.5-3.0 wt% adhesive and is prepared using a high-pressure hot-pressing process at 300-1000 MPa, resulting in a point-contact distribution of the adhesive at the microscopic level. This invention resolves the contradiction between adhesive solubility and the chemical stability of the sulfide electrolyte, achieving high peel strength and low interfacial resistance of the electrode with extremely low adhesive content. This effectively buffers the volume expansion of the active material, improving the cycle life, low-temperature performance, and rate performance of the all-solid-state battery.

A laparoscopic electrocoagulation hook with smoking function
ActiveCN224269421UIncreased durabilityImprove operational stabilityDirt cleaningSurgical instruments for heatingTissue fluidSmoke Emission
This utility model relates to the field of medical device technology and discloses a laparoscopic electrocoagulation hook with a smoking function. It includes a handle, a sleeve, an electrocoagulation rod, and an electrocoagulation hook head. A negative pressure absorption assembly is connected to the end of the sleeve away from the electrocoagulation hook head. A trigger switch for controlling the negative pressure absorption assembly is provided on the outer side of the handle. Several smoking holes are perforated through the outer wall of the sleeve near the electrocoagulation hook head. This laparoscopic electrocoagulation hook with a smoking function allows the trigger switch on the handle to activate the negative pressure absorption assembly to extract air from inside the sleeve. The smoke generated during surgery is then extracted through multiple smoking holes at the end of the sleeve, ensuring clear visibility of the surgical environment. The array design of multiple smoking holes significantly improves smoke collection efficiency, ensuring a clear surgical field. Furthermore, it effectively reduces the obstruction of the smoking channel by surgical exudates such as blood and tissue fluid during surgery, significantly improving the durability and operational stability of the laparoscopic electrocoagulation hook.

A protective mechanism for welding machines
This utility model relates to the technical field of welding protection equipment, specifically a protective mechanism for a welding machine, including a frame; the frame is equipped with a protective mechanism and a collection mechanism; the protective mechanism includes a protective frame, which is slidably connected to the side of the frame, and a protective cover is fixedly connected to the middle of the protective frame, with ventilation holes on the inner side of the protective frame. The ventilation holes serve as an air inlet and an air outlet, thereby forming a flowing gas barrier between the ventilation holes to guide and collect the fumes generated during welding. Simultaneously, the flowing gas can block splashing sparks, reducing the surface temperature of the sparks before they contact the protective cover, thus reducing damage to the protective cover. The flowing gas can also blow lighter sparks away from the protective cover. By reducing damage to the protective cover or reducing the amount of fume particles adhering to its surface, the service life of the protective cover is increased, and the frequency of maintenance or cleaning is reduced.

A pickling box for jewelry production
This utility model relates to the field of jewelry manufacturing technology, specifically disclosing a pickling tank for jewelry production. The tank includes a body with a loading basket suspended from a lifting device via a conveyor belt. An inlet / outlet is located on the top cover of the tank, with a sealing cap at each inlet / outlet. The conveyor belt can move up and down when the sealing cap closes the inlet / outlet. A rotating platform is located at the bottom of the tank, housing an acid tank, an electric heating furnace, and a water tank. The electric heating furnace has electric heating sources on its side walls and bottom. Rotating the rotating platform positions the acid tank or water tank directly below the loading basket. An exhaust system is connected to the tank. A temperature sensor is mounted on the electric heating furnace, and the electric heating sources are connected to a controller, which in turn is connected to the temperature sensor. The electric heating furnace heats the acid tank from the side and bottom, increasing the heating area and improving thermal efficiency. During pickling and washing, the tank is sealed, and the exhaust system extracts the acidic gases, reducing their diffusion.

Air duct structure adopting lateral shell for lateral air intake and air fryer
The utility model discloses an air duct structure and an air fryer adopting a lateral shell for lateral air intake, and relates to the technical field of air fryers, the air duct structure comprises an air fryer shell, a bottom plate and a support column, and the bottom end of the air fryer shell is provided with the bottom plate. Through holes are formed in the side edges of the air fryer shell and the bottom plate, meanwhile, a gap can be formed between the air fryer shell and a placement table top through the supporting columns, air flow can conveniently circulate on the side edges, then air can conveniently circulate in the air fryer, cold air can rapidly flow into the top end of the air fryer shell, and the air fryer shell can be conveniently placed on the air fryer. The heat dissipation fan in the neutralization fan is used for extracting relatively hot air inside, and the neutralization fan is used for neutralizing the sucked air flow and the hot air inside the exhaust pipe, so that the temperature can be quickly reduced, and then the air can be exhausted to the outer side through the heat dissipation net; therefore, the air fryer can improve the internal heat dissipation effect by adopting the air duct structure with air entering from the side edge.
