The invention belongs to the technical field of batteries, and particularly discloses a battery cell, at least one end of a shell of the battery cell is provided with an opening, a cover plate is arranged at the opening, and the cover plate and the shell jointly define an accommodating space for mounting a pole group. An abutted seam is formed between the circumferential side wall of the cover plate and the inner wall of the shell. In the first direction, the end face of the cover plate away from the pole group side is higher than the end face of the shell towards the cover plate side, so that a step part is formed therebetween. On the outer side, away from the containing space, of the abutted seam, the shell and the cover plate are welded and connected at the step part to form a welding part, an included angle is formed between the melting direction when the welding part is formed and the plane where the cover plate is located, the melting direction faces the circumferential side wall of the cover plate, and the plane where the cover plate is located is perpendicular to the first direction. By means of the welding mode that the laser for welding the shell and the cover plate inclines relative to the cover plate, the risk that the laser leaks into the containing space from the abutted seam when the shell and the cover plate are welded is reduced, the pole group is prevented from being burnt, and meanwhile reliable connection between the shell and the cover plate is guaranteed.

The application discloses a steam exhaust condensation recovery system, which comprises a transfer box, a condensation box, a steam exhaust device, a steam input pipe and a condensation return water pipe connected with the transfer box, a steam output pipe and a condensation return pipe connected with the transfer box and the condensation box, and a steam exhaust pipe connected with the condensation box and the steam exhaust device. The steam input pipe is used for receiving steam output by a cooking device, and the steam exhaust device is used for exhausting steam to the outside. The steam exhaust condensation recovery system forms a steam exhaust path and a condensation water exhaust path. The application further discloses an integrated cooker with the steam exhaust condensation recovery system. The steam exhaust condensation recovery system has the advantages that water stains formed on a table board, a wall surface and the like are reduced, and condensation water can be recycled.

The utility model discloses an organic glass jig of inlaying blow -off channel relates to laser plastic hot melt welding jig technical field, including the pressing plate of organic glass material quality, the top central position of pressing plate is equipped with the through cavity, the bottom of through cavity penetrates the bottom wall of pressing plate, the top fixedly connected with the baffle of pressing plate, the baffle is located the right above through cavity top and will through cavity top completely cover. Through being equipped with the through cavity and air -cooled component, again cooperation baffle to the block of cold air, make air -cooled component can control cold air flow through the top surface of upper layer material to be welded, thereby can carry out the cooling to upper layer material to be welded, so even if the upper layer material to be welded transmittance reduces and leads to too much absorption laser heat and produces high temperature, this organic glass welding jig can also take away the heat of the upper layer material to be welded of poor transmittance in time and avoids its being burned or deformed, thereby effectively expands the application range of laser plastic welding process.
