The utility model relates to electric heating pipe technical field, and disclose a kind of leakproof glue structure for electric heating pipe processing, including base and electric heating tube, the end of support plate is fixedly installed with support, the middle part of support is fixedly installed with connecting plate, the electric heating tube is inserted in the middle part of connecting plate, O flat pad is placed in the middle part of connecting plate, the middle part of support is provided with sleeved washer assembly, the electric heating tube is located in the bottom center of sleeved washer assembly directly below;By pressing down pressure plate, it will drive inner sleeve to pass through O flat pad downwards, so that O flat pad is sleeved on the outside of inner sleeve, it will also be sleeved on the outside of electric heating tube, and because compression spring is compressed, after releasing pressure plate, it will drive inner sleeve to reset upwards under the action of compression spring, so that O flat pad and outer sleeve contact, and it will be pressed downwards relative to inner sleeve by outer sleeve, it will be completely sleeved on the outside of electric heating tube located in inner sleeve, so that it can be completely sleeved washer.

The utility model relates to the field of tobacco tar injection equipment, in particular to leakage-proof oil injection equipment which comprises a needle head body and a connecting piece, the needle head body is communicated with a plurality of oil injection needles, one end of the connecting piece is connected with the needle head body, and the other end of the connecting piece is connected with a sealing plug. The plane where the bottom of the sealing plug is located is lower than the plane where the tail ends of needle heads of all the oil injection needles are located. The outer diameter of the sealing plug is larger than or equal to the diameter of the heating wire assembly hole. The sealing plug is arranged, the position of the sealing plug is lower than the positions of the tail ends of the needle heads of all the oil injection needles, and meanwhile it is ensured that the outer diameter of the sealing plug is larger than or equal to the hole diameter of the heating wire assembly hole, so that the heating wire assembly hole is effectively plugged, and oil liquid is prevented from leaking from the hole. By means of the design, the problem that oil liquid is prone to leakage when the heating core is not installed in a traditional oil injection mode is fundamentally solved.
