Description
Technical Field
The utility model relates to an electron cigarette technical field especially discloses an electron tobacco tar atomizing is micropore ceramic thick film heating element for core.
Background
The tobacco tar type electronic cigarette is a virtual cigarette and is an alternative product of the traditional cigarette. The structure of the device comprises an electronic atomizer (containing tobacco tar and a heating atomization component), and a tobacco rod (containing a battery, a control circuit and an airflow inductor component). The working principle is that a battery is communicated with a heating element of an atomizer through a control circuit and an airflow sensor element in a cigarette rod, voltage is applied to the heating element of the atomizer, the heating element is heated to about 130 ℃ to 150 ℃, so that a tobacco tar solution containing nicotine, tobacco special essence, propylene glycol and vegetable glycerin in an oil bin of the atomizer is atomized into particles, and the particles are dispersed into an aerosol form by matching with inhaled air airflow, so that smoke simulating smoke is formed.
Compared with the traditional common cigarette, the tobacco of the traditional common cigarette generates thousands of carcinogenic harmful compounds such as tar, carbon monoxide, nitrosamine, radioactive substances and the like under the high-temperature condition when being burnt. The tobacco tar type electronic cigarette basically only contains nicotine and edible glycerin in smoke generated by tobacco tar atomization, so that the physiological needs and psychological needs of smoking consumers are met. Therefore, the tobacco tar type electronic cigarette reduces the harm of smoking consumers and the influence of public environment to a certain extent.
Through the development of several years, the heating elements adopted by the current domestic and foreign smoke type electronic smoke atomizer can be roughly classified into the following forms according to the development time sequence: first generation atomizer heating element: the oil guide cotton or the glass fiber rope is wound with a nichrome heating wire; the second generation of atomizer heating element: the porous ceramic is wound with a nickel-chromium alloy heating wire; the third generation of atomizer heating element: a buried-burning nickel-chromium alloy heating wire is added into the porous ceramic; schematic diagrams of the three types of atomizing core heating elements are shown in figures 1-3.
The first generation of atomizer heating element is a nichrome heating wire wound around the outside or inside of an oil-guiding cotton or a glass fiber rope. The defects of the heating element device of the atomizer are as follows: 1. the fine filaments in the glass fiber strands risk being inhaled into the lungs by the consumer; 2. the oil guide cotton or the glass fiber rope is easy to be burnt at the working temperature of the electronic cigarette to generate carcinogenic substances, which are harmful to the health of people and reduce the safety of the atomizer; 3. the heating area of the heating wire is small, the working temperature is high, tobacco tar is easily carbonized, peculiar smell is generated, and the taste and the service life of the electronic cigarette steam are influenced.
The second generation atomizer heating element device uses porous ceramic formed by high-temperature firing to replace oil guide cotton or glass fiber ropes, and a nichrome heating wire is wound outside the porous ceramic. Although the second generation of atomizers avoided the problem of oil cotton or fiberglass rope coking of the first generation of atomizers to some extent. However, the second generation of atomizer heating element has the defects that the nickel-chromium alloy heating wire is wound outside the porous ceramic, the heating wire is not in sufficient contact with the microporous ceramic substrate, so that the tobacco tar cannot be fully soaked into the heating wire, part of the heating wire which is not soaked by the tobacco tar is in a dry-burning state, the working temperature of the heating wire is too high, the tobacco tar is scorched, and the taste of the electronic cigarette steam is greatly influenced.
In the third generation of atomizer heating element device, an integral injection molding process is adopted, wherein a nickel-chromium alloy heating wire is embedded in a porous ceramic green body, and the porous ceramic green body and the nickel-chromium alloy heating wire are fired together at the temperature of about 600 ℃. The nichrome element of the heating element of the atomizer is embedded in porous ceramic, so that the problem of tobacco tar infiltration of the heating element of the second-generation atomizer is solved. However, when the nichrome wire is sintered at a high temperature of 1300 ℃ or higher, the alloy wire is oxidized and blackened, which affects the heating characteristics and the resistance characteristics. Therefore, in order to avoid the problem that the nickel-chromium alloy wire is black due to sintering oxidation at high temperature, the sintering temperature of the sintered porous ceramic is reduced from 1300 ℃ to about 600 ℃ in the manufacturing process. This causes the porous ceramics of the heating element device of the atomizer to have a loose structure because the sintering temperature is too low and the strength of the ceramic body is not enough. When the porous ceramic heater is soaked in the tobacco tar for a long time, the ceramic body of the porous ceramic is easy to fall off, and the risk that the ceramic powder separated by stripping is inhaled into the lung of a consumer can be easily caused. Meanwhile, the heating wire buried in the porous ceramic is easy to cause carbon deposition blockage of micropores of the porous ceramic in the working process, so that tobacco tar is burnt, and the taste and the reduction degree of the tobacco tar are influenced.
To sum up, the existing first-generation oil guide cotton or glass fiber rope with a winding nickel-chromium alloy heating wire, the second-generation porous ceramic with a winding nickel-chromium alloy heating wire and the third-generation porous ceramic with a buried burning nickel-chromium alloy heating wire all have various defects and problems, and the performance requirements of the development of electronic cigarette products on the atomizer heating device cannot be met.
