Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and in particular to an oil storage bin structure with cyclic exhaust and an electronic cigarette provided with the structure. Background Art

[0002] At present, the oil storage cotton type electronic cigarettes on the market have oil storage cotton set in the oil storage bin (also called oil cup). The oil storage cotton usually adopts integrated cotton, which is used to store smoke oil and has the advantages of easy assembly, high oil locking, and stable oil conduction. Usually, the oil storage cotton is filled in the oil storage bin, and silicone parts are provided at the upper and lower ends. The oil storage bin is connected to the atomization core in the atomization ventilation duct. When in use, the smoke oil of the oil storage cotton is guided into the atomization ventilation duct through the atomization core, and the smoke oil is atomized into steam aerosol smoke by electrically heating the atomization core. However, when the oil storage bin is in a high temperature environment, the oil storage cotton will expand due to the heat. At this time, the exhaust fails to be timely, which increases the pressure in the oil storage cavity and easily causes oil leakage at the connection between the oil storage bin and the atomization core in the atomization ventilation duct. In addition, during the use of electronic cigarettes, negative pressure will be formed in the oil storage tank. If the pressure is not released in time or the pressure relief effect is poor, the oil storage cotton will expand, which will cause the smoke oil to concentrate or flow out, thereby increasing the oil storage cotton's oil seepage from the atomization core, causing oil leakage, thus affecting the user's experience. The existing solution usually provides a pressure relief hole on the upper sealing silicone part of the oil storage tank, but it does not achieve a good exhaust and pressure relief effect. Therefore, it is necessary to develop and improve the existing oil storage cotton type electronic cigarette to solve the above problems. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model proposes an oil storage bin structure with circulating exhaust to solve the problem that the exhaust and pressure relief effects of the existing oil storage cotton type electronic cigarette are poor.

The first exhaust channel and the second exhaust channel are respectively arranged at the left and right outer positions of the first channel. An exhaust groove is provided on the front and rear side walls of the oil storage integrated cotton corresponding to the first exhaust channel and the second exhaust channel.

[0009] Furthermore, the upper sealing silicone is provided with a first exhaust channel docking through hole corresponding to the upper end of the first exhaust channel, and a second exhaust channel docking through hole corresponding to the upper end of the second exhaust channel. The first exhaust channel docking through hole and the second exhaust channel docking through hole are provided with a groove connecting the first channel docking through hole.

[0010] Furthermore, the upper surface of the upper sealing silicone is provided with a convex edge in the peripheral area of ​​the docking through hole on the first channel, the docking through hole on the first exhaust channel, and the docking through hole on the second exhaust channel. The convex edge and the upper sealing silicone form a groove position, and an oil-absorbing cotton block is provided in the groove. The oil-absorbing cotton block is provided with a through hole corresponding to the position of the docking through hole on the first channel.

[0011] Furthermore, the atomization channel tube is a glass fiber tube or a stainless steel tube, and the upper end of the atomization channel tube is inserted into the docking through hole on the first channel.

[0013] The technical solution also discloses an electronic cigarette, in which the above-mentioned circulating exhaust oil storage tank structure is provided.

[0014] The beneficial effects of the utility model are as follows: the oil storage bin structure of the electronic cigarette designed by the technical solution is configured such that an exhaust channel for exhaust is provided on the first channel side of the atomization channel inside the oil storage integrated cotton in the oil storage tube body, and an exhaust groove is provided on the outer wall of the oil storage integrated cotton, so that the exhaust groove and the exhaust channel form a 360-degree circulating exhaust inside and outside the oil storage integrated cotton, which helps to exhaust and relieve pressure of the electronic cigarette in time during use through the circulating exhaust structure, thereby achieving better exhaust and pressure relief effects and balancing the pressure in the oil storage tube body.

[0015] When the electronic cigarette is in use or the external environment affects and negative pressure is formed inside the oil storage bin, the integrated oil storage cotton expands, and the oil in the integrated oil storage cotton will be concentrated or flow out. The oil will enter the exhaust channel set in the integrated oil storage cotton. The exhaust channel has the function of storing the oil. After the pressure is balanced, the oil will be absorbed by the integrated oil storage cotton, thereby keeping the exhaust channel unobstructed again. Therefore, the phenomenon of oil overflow and leakage of electronic cigarettes is effectively reduced. BRIEF DESCRIPTION OF THE DRAWINGS
