Definitions

  • the invention relates to the field of electronic heating atomization devices, and in particular to an electronic heating atomization device with multi-channel liquid supply.
  • Electronic heating atomization technology is a method of using electricity to heat the atomizing liquid to reach its boiling point to produce an aerosol mixed with steam and air.
  • Electronic atomizing devices are widely used in the field of electronic cigarettes. Its working principle is to conduct the atomizing liquid from the liquid storage end to the atomizing surface located in the air flow channel through the capillary pores inside the liquid-conducting material.
  • a heating element is provided on the atomizing surface. When the heating element is powered, the heating element on the atomizing surface will generate heat due to the thermal effect of the resistor, heating the atomizing liquid to the boiling point and producing atomized steam.
  • the atomized steam and the air entering the atomizer are mixed to form an aerosol substance, which is commonly known as smoke.
  • the continuous atomization process requires a continuous and sufficient supply of liquid through the liquid-conducting material, and at the same time, it cannot be supplied too much.

  • liquid enters from both ends of the liquid guiding parts made of liquid guiding materials, and the liquid guiding parts conduct the liquid from the liquid storage tank to the heating element for heating and atomization. Since the liquid is transferred from both ends to the middle through the capillary action of the liquid guiding parts, the liquid reaches some parts of the liquid guiding parts far away from the two ends, or the density of some parts of the liquid guiding parts is different, which causes the liquid to reach these parts at a slower speed, resulting in the heating element being too hot due to insufficient liquid supply, causing dry burning and other problems, affecting the taste of the smoke.

Description

多通道供液的电子加热雾化装置 技术领域
本发明涉及电子加热雾化装置领域，尤其是涉及一种多通道供液的电子加热雾化装置。
 背景技术
电子加热雾化技术是一种利用电加热雾化液，使其达到沸点产生蒸汽和空气混合而成的气溶胶，电子雾化装置广泛应用于电子烟领域。其工作原理是通过导液材料内部的毛细微孔将雾化液由储液端传导到位于气流通道内的雾化面上，位于雾化面的设有发热件，当给发热件供电，由于电阻的热效应，雾化面的发热体会发热，将雾化液加热至沸点，产生雾化蒸汽，雾化蒸汽和进入雾化器的空气混合就形成了气溶胶物质，也就是俗称的烟雾。而持续的雾化过程需要通过导液材料持续供液充足，同时不能供应的过多，液体过多会导致容易漏液，因此如何保证液体能充足供应较为重要。
通常液体从导液材料制成的导液件的两端进液，导液件将液体从储液仓传导到发热件上加热雾化，由于液体是通过导液件的毛细作用从两端到中间，液体到达导液件某些部位距离两端较远，或者导液件某些部位的密度不同，就导致液体到达这些部位的速度较慢，从而导致发热体因供液不足而温度过高，产生干烧等问题，影响烟雾口感。
