The utility model provides a novel atmosphere stove, includes furnace body and furnace gate, the upper portion of furnace body is equipped with gas outlet, its characterized in that: the device also comprises a detection device and a furnace door sealing device; the detection device comprises a vent pipe connected with the air outlet, the furnace door sealing device comprises rollers, an inclined block and a fastening device, the furnace door is connected with the furnace body through the two rollers, and the two rollers are connected through the inclined block, so that the moving range of the furnace door is enlarged; the fastening device comprises a handle, a screw rod and a support, the support comprises a fixed end and a movable end, the bottom end of the handle is hinged to the fixed end, a sliding groove is formed in the movable end, a sliding block matched with the sliding groove is arranged in the middle of the handle, the handle drives the movable end to move up and down through the sliding block, and the screw rod is clamped at the tail end of the sliding groove of the movable end.

Preferably, the lower part of the furnace body is provided with universal wheels.

Preferably, the atmosphere furnace is electrically heated.

Preferably, the number of the fastening devices is 4, and the fastening devices are respectively arranged at four corners of the furnace door.

Preferably, the vent pipe is connected to a gas flow meter or a water tank.

Preferably, the vent pipe is a plastic hose.

The utility model has the advantages that:

the utility model discloses simple and practical is equipped with detection device on the device of current atmosphere stove. The user monitors whether the content of the inert gas in the atmosphere furnace meets the requirement or not in time according to the gas output of the detection device. The utility model discloses a sealing device, when opening, the furnace gate is contactless with the furnace body, and the work piece of conveniently taking adopts special fastener, makes the four corners of furnace gate and the laminating that the furnace body can be better, prevents that gas leakage from taking place.
