Description

Novel electronic atomization core

Technical Field

The invention relates to the technical field of electronic cigarettes, in particular to a novel electronic atomization core.

Background

The electronic cigarette is an electronic product simulating a cigarette, and has the same appearance, smoke, taste and sensation as the cigarette. The atomizer is powered by a rechargeable lithium polymer battery, and the smoke oil in the oil tank is heated to be changed into steam, so that a user can absorb the steam. The electronic cigarette is used as a substitute for cigarette products and is mainly used for quitting smoking. Electronic cigarettes have an appearance and taste similar to cigarettes, but generally do not contain other harmful components such as tar, aerosols, etc. in cigarettes.

The key part of the electronic cigarette for generating atomization is the atomizer, and the core component in the atomizer is an atomization core. The ceramic atomization core heating technology is generally adopted in the existing market, a bowl-shaped ceramic main body is adopted, a bent resistance wire shape is formed at the bottom of the ceramic main body through a printing resistance wire and is arranged on the bottom surface of the bowl of the ceramic main body, the ceramic main body is used for loading smoke oil, the smoke oil is seeped downwards through holes in the ceramic main body, and the smoke oil is heated by the heating resistance wire printed on the bottom surface to form smoke and then returns to the two sides of the bottom of the bowl for output. The main drawbacks of this technique are: (1) the process of printing the resistance wire is restricted by the area of the bottom surface of the ceramic main body, in order to obtain larger heating amount to increase the smoke amount, the heating amount of the resistance wire needs to be increased, the resistance value of the resistance wire needs to be increased, and thinner resistance wire needs to be printed, however, the resistance wire is too thin, so that the difficulty of the printing process is increased, and the printed resistance wire is easy to burn off in the heating process due to the too thin resistance wire, so that the atomizing core is directly scrapped; (2) the daily drive of the tobacco tar atomizer is miniaturized, the original design volume of the ceramic main body is very small, the oil storage capacity of the existing bowl-shaped ceramic main body is small, the oil guide flow is small, the atomized smoke is also small, and the oil leakage speed of ceramic pores is slow, so that the requirement of a user on large smoke volume is difficult to meet; (3) because the resistance wire is the printing in the bottom of ceramic subject's bowl form, the printing resistance wire who meanders to lay so can plug up some hole export, atomization effect has not only been reduced, still can lead to using after a period like this, stifled tobacco tar on the hole by the shutoff can be continuous by the heating but can not send out, cause the tobacco tar to become the old oil that heats a lot of, because the multiple heating causes by stifled tobacco tar carbonization scorching, the cigarette that the atomizing core atomizing was come out can produce burnt flavor and carry other harmful substance, thereby make the aspirator can discover after using several times that the cigarette flavor becomes heavy etc. and use the obvious difference of new atomizing core, and then influence user experience.

In a further embodiment, the top end of the conductive electrode 3 is respectively inserted into the bottom of the liquid guiding base 1 and connected to two ends of the meshed metal heating sheet 2, so as to avoid the problem that the conductive electrode 3 falls off from the liquid guiding base 1 and is in poor contact with the meshed metal heating sheet 2 during use, thereby causing circuit disconnection, preferably, the conductive electrode 3 is provided with the counter hook part 31, the counter hook part 31 is a columnar or flat fixing structure vertical to the conductive electrode 3, and the conductive electrode 3 is further fixed inside the liquid guiding base 1 to prevent the conductive electrode 3 from falling off; of course, the counter hook 31 may also be a structure having any non-zero included angle with the lead electrode, so as to prevent the conductive electrode 3 from being easily pulled out and damaged when the conductive electrode 3 is pulled outwards; according to the invention, the flow blocking net piece is arranged above the net-shaped metal heating piece 2 in the oil guide channel 11, so that the flow limiting or throttling function is realized, the flow velocity of the tobacco tar is limited, and the purpose of adjusting the atomization amount of the tobacco tar is achieved; according to different requirements of customers, the flow blocking net piece can be added, different suction feelings are realized, and comfortable suction experience is provided for users more humanizedly.

According to the novel electronic atomizing core, the oil guide channel 11 penetrates from the top to the bottom of the oil guide base body, so that the oil storage volume of the oil guide channel 11 is increased, the oil storage capacity is large, the sufficient smoke oil flow can be ensured, meanwhile, the oil storage capacity can be increased due to the structure, a designer can be allowed to design the size of the liquid guide base body 1 to be smaller, and the space for overall more miniaturized design of an atomizer is provided; the netted metal generates heat piece 2 and directly paves in leading the terminal smog export that sets up of oil passageway 11 for netted metal generates heat piece 2 can be directly with lead the tobacco tar contact in the oil passageway 11, and the water conservancy diversion is fast, and each part of netted metal generate heat piece 2 fully contacts the tobacco tar, and the atomizing area is big and generate heat evenly, makes atomizing smog big, satisfies more users' user demand.

The above description is only an exemplary embodiment of the present invention, and is not intended to limit the scope of the present invention. Any equivalent changes and modifications that can be made by one skilled in the art without departing from the spirit and principles of the invention should fall within the protection scope of the invention.
