Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, in particular to an electronic cigarette which is convenient for replacing cigarette liquid. Background Art

[0002] Electronic cigarettes are electronic devices designed to simulate the traditional smoking experience. Other ingredients can be added to the smoke liquid to form different flavors, among which fruit, mint or candy flavors are the most common. During the use of electronic cigarettes, users usually need to separate the mouthpiece from the oil cup according to their personal preferences, so as to add their favorite smoke liquid into the oil cup;

[0003] However, when assembling the suction nozzle and the oil cup, the injection molding precision during the production of the suction nozzle and the oil cup is relatively low, which often leads to a large degree of fit between the suction nozzle and the oil cup. After multiple disassembly and assembly, the gap between the suction nozzle and the oil cup becomes larger, which leads to problems such as loose assembly and poor sealing. At the same time, when assembling the suction nozzle and the oil cup, the air in the oil cup cannot be discharged in time, causing the air in the oil cup to lift up the suction nozzle, which in turn leads to the problem that the suction nozzle cannot be assembled in place. Summary of the invention

[0004] The purpose of the utility model is to provide an electronic cigarette that is easy to replace the e-liquid, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electronic cigarette which is convenient for replacing smoke liquid, comprising a suction nozzle and an oil cup, the bottom end of the suction nozzle being inserted into the top port of the oil cup, the hole axis being interference fit between the suction nozzle and the oil cup, a suction nozzle fixing ring being clamped inside the bottom end of the suction nozzle, the suction nozzle fixing ring propping up the inside of the bottom end of the suction nozzle, a silicone sealing ring being sleeved on the inner wall of the suction nozzle fixing ring, a stamping air outlet rod being arranged inside the oil cup, a lower liquid inlet hole being provided on the outer wall of the stamping air outlet rod, the top end of the stamping air outlet rod being inserted into the suction nozzle, an exhaust hole being provided on the upper part of the stamping air outlet rod, the silicone sealing ring being sleeved on the top outer wall of the stamping air outlet rod, and the exhaust hole being covered by the silicone sealing ring, and an oil cup upper fixing ring being sleeved on the top outer wall of the stamping air outlet rod.

[0006] Furthermore, a nozzle cap is provided at the top end cover of the nozzle, and both the nozzle cap and the nozzle are made of PC material.

[0007] Furthermore, the cigarette holder fixing ring and the oil cup upper fixing ring are both stainless steel fixing rings.

[0008] Furthermore, a ceramic core is provided inside the bottom end of the stamped air outlet rod, oil-absorbing cotton is provided at the bottom of the ceramic core, an external threaded part is provided on the internal thread of the bottom port of the oil cup, the bottom end of the stamped air outlet rod is inserted into the top end of the external threaded part, and a non-woven fabric is provided on the outer wall of the bottom end of the stamped air outlet rod, and the non-woven fabric covers the lower liquid inlet hole on the stamped air outlet rod, and the non-woven fabric is fixed to the stamped air outlet rod by an O-ring.

[0009] Furthermore, an insulating sleeve is fixedly provided on the inner wall of the external threaded part, an electrode is clamped on the inner wall of the insulating sleeve, and the energized end of the electrode contacts the ceramic core through the oil-absorbing cotton.

[0010] Furthermore, the bottom end of the oil cup is sleeved with an oil cup lower fixing ring, and the oil cup lower fixing ring is a stainless steel fixing ring.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The connection between the nozzle and the oil cup is supported by the cigarette holder fixing ring and the oil cup upper fixing ring, and a seal is formed on the interference fit surface by the elastic silicone sealing ring. This design is very flexible. By selecting cigarette holder fixing rings and oil cup upper fixing rings of different sizes to match the nozzle and the oil cup, the relatively low injection molding precision can be compensated, and the effect of fast assembly and stable sealing can be achieved.

[0013] Through the upper exhaust hole of the stamped air rod, when the suction nozzle is inserted into the oil cup, the air in the oil cup can enter the stamped air rod, and then enter the suction nozzle, and finally be discharged from the opening on the top of the suction nozzle, ensuring that the suction nozzle can be inserted into place. After the suction nozzle is inserted into place, the silicone sealing ring covers the upper exhaust hole of the stamped air rod to form a seal, which requires a small sealing space below the exhaust hole and less air is trapped, thereby achieving the purpose of quickly exhausting the air in the oil cup and allowing the suction nozzle to be assembled in place.
