The utility model relates to the technical field of heating ventilation air conditioning, disclose a kind of outdoor heating ventilation air conditioner with protection function, including heating ventilation air conditioner outdoor unit;Protection mechanism is equipped on the heating ventilation air conditioner outdoor unit;The protection mechanism includes waterproof shed, adjusting lever, water collecting box and connecting rod;The adjusting lever is set to the both sides of heating ventilation air conditioner outdoor unit, is located heating ventilation air conditioner outdoor unit upper end portion, and one end of adjusting lever is rotatably connected with heating ventilation air conditioner outdoor unit;One side of waterproof shed is fixed in the lower side of adjusting lever;The water collecting box is set to the both sides of heating ventilation air conditioner outdoor unit, is located heating ventilation air conditioner outdoor unit lower end portion;The connecting rod is fixedly installed in the side of water collecting box close to heating ventilation air conditioner outdoor unit.The utility model has solved the problem that internal electrical components cannot be protected because heating ventilation air conditioner outdoor unit is not covered on rainy days.

This utility model belongs to the technical field of steel grating, specifically disclosing a drainage ditch steel grating that is easy to clean. It includes a main body and seepage channels. Five sets of seepage channels are arranged between the front and rear of the main body. A left fixing block is fixed to the rear left side of the bottom of the main body, and a right fixing block is fixed to the rear right side of the bottom of the main body. A threaded rod is laterally movably connected between the left and right fixing blocks. This easy-to-clean drainage ditch steel grating utilizes the threaded rod movably connected between the left and right fixing blocks. Pushing the stop block horizontally towards the hidden slot above the slot exposes the handle. Rotating the handle rotates the second gear connected at the bottom, thereby pushing the first gear meshing on the left side. The threaded rod rotates between the left and right fixing blocks, and under the restriction of the front and rear limiting slots, pushes the stop plate horizontally to cover the seepage channels, or removes the stop plate to expose the seepage channels, thus solving the problem of inconvenient opening and closing.

The invention relates to the technical field of lithium ion batteries, in particular to a battery cell, a battery pack and electric equipment. The disclosed battery cell comprises a shell, a cover plate and an anti-explosion valve, the shell comprises a base material, a welding area is arranged on the base material in the length or width direction of the shell, and heat affected areas are formed on the two sides of the welding area. The cover plate is arranged at the open end of at least one side of the shell; the anti-explosion valve is arranged on the cover plate; in the thickness direction of the anti-explosion valve, a nick is formed in the end face of the anti-explosion valve, an opening face is defined by one side of the nick, and the projection area of the opening face is S0; the projection area of the cover plate is S2; the average grain size of the heat affected area is A1, the average grain size of the base material is A2, and S0, S2, A1 and A2 meet the condition that 7 < = 11. According to the battery cell, the influence of the welding temperature on the battery cell can be effectively reduced, the structural strength of the battery cell is not reduced, and the safety performance of the battery cell is improved.
