Liquid nitrogen nail gun device

Abstract

The invention relates to a liquid nitrogen nail gun device which comprises a gun barrel, a gasification chamber, a motor and a handle. The gun barrel is located at the uppermost part of a nail gun, and the lower portion of the gun barrel is connected with an upper end opening of the gasification chamber. The upper end opening of the gasification chamber is of a necking-down structure. A liquid inlet is formed in one side of the top of the gasification chamber. The gasification chamber is of a double-layer structure, and a vacuum interlayer is arranged between the inner wall and the outer wallof the gasification chamber. Fan blades are arranged in the gasification chamber, the fan blades are connected with a motor through a connecting metal bearing, and the motor is connected with the handle. The gasification chamber is a power generation cavity needed by nail shooting and is used for storing liquid nitrogen and water, and the liquid nitrogen is finally gasified to generate pressure. The fan blades are started through the motor to fast rotate, due to the fan blades which rotate rapidly in the gasification chamber, the liquid nitrogen and water can be rapidly mixed, the gasificationrate of the liquid nitrogen is rapidly increased when the liquid nitrogen meets water, generated high pressure provides power, and then the nails can be shot up rapidly. By means of the liquid nitrogen nail gun device, the problem that when a traditional nail gun is used, heat emitting happens, and safety cannot be ensured is solved; and the device overall has the beneficial effects that the structure is simple, potential safety hazards are eliminated, and environment friendliness is achieved.

Description

technical field [0001] The technical solution of the present invention relates to a liquid nitrogen nail gun device, specifically a kinetic energy generating device that generates instantaneous high pressure through rapid gasification of liquid nitrogen to generate kinetic energy. Background technique [0002] A nail gun, a tool used to drive nails into wood, walls, etc., has in many ways replaced the hammer as the builder's tool of choice. Existing nail guns can be mainly divided into pneumatic nail guns, powder-driven nail guns, combustion-powered nail guns, electric nail guns, and electromagnetic-driven nail guns according to the source of power. These nail guns usually use compressed air (pneumatic), electromagnetic drive, highly flammable gas or gunpowder to gasify in the cavity, thereby forming power, and the nail is shot out by the nail gun needle. The problem that present nail gun exists is: the first, for the nail gun of electric and combustion power, especially be...
