In order to adapt to different application scenarios, improve welding quality, people constantly propose the electric iron of various improvement and various solder horn being suitable for various welding object.Chinese patent mandate publication number is CN201702484U, the solder horn in authorized announcement date on January 12nd, 2011, provide a kind of end of welding to be provided with Baltimore groove and solder horn end being divided into two heating blocks, storing up during soldering in the middle of tin groove is not subject to ectocine to reach energy-conservation object, and its shortcoming is suitable only for the larger solder joint of welding.Chinese patent mandate publication number is CN2027880151U, a kind of solder horn in authorized announcement date on March 13rd, 2013, provide a kind of solder horn of U-shaped welding end, U-shaped width is suitable with the width of surface-mounted device, can easily for directly welding or dismounting surface-mounted device, but its shortcoming is that the adaptable device of this structure is more single.Chinese patent mandate publication number CN203109400U, authorized announcement date is a kind of electric soldering bit on August 7th, 2013, provide a kind of solder horn being provided with triangle storage tin groove in welding end, once inhaling tin can multiple welding, but its shortcoming is this structure easily produces the too much problem of solder joint scolding tin.
Summary of the invention
Problem that the purpose of this utility model is for existing electric soldering bit complex structure and limitation is strong etc., provide a kind of structure simple, inhale that tin is many, welding effect good, electric soldering bit applied widely.
The utility model adopts following measure to reach:
A kind of electric soldering bit, comprise heating part and heat-conducting part, heat-conducting part is a heat conducting bar, the rear end of heat conducting bar is connected with heating part, front end is provided with the solder side of inclination, it is characterized in that solder side rear end and heat conducting bar are provided with the storage tin groove be connected, the width of storage tin groove diminishes from front to back gradually, and the degree of depth of storage tin groove diminishes from front to back gradually.
Storage tin slot opening area described in the utility model is not more than 1/3rd of solder side surface area, to prevent scolding tin from upwards assembling too much, prevents shortage of heat from affecting and inhales tin effect.
Storage tin channel section described in the utility model is part circular, makes scolding tin arrive pad more uniformly.
Storage tin groove described in the utility model is provided with and guides V-type groove, and the inclined-plane guiding scolding tin to flow through solder side lentamente reaches on the device that will weld.
Electric soldering bit of the present utility model is when carrying out weld job and inhaling tin, scolding tin can be sucked in storage tin groove, and the inclined-plane that these scolding tin sucked in storage tin groove can flow through solder side lentamente by the effect of molecule stress when welding reaches on the device that will weld, to reach good welding effect, the utility model has inhales the advantages such as tin amount is large, welding efficiency is high, applied widely.
