Description

Micromotor pump liquid formula electron cigarette

Technical Field

Currently, precision manufacturing and assembly of tiny components with dimensions from the millimeter to the micrometer scale have become an area of much industrial interest. The micro-driving device can perform small actions and has high position precision, and is typically applied to the fields of cell manipulation, automatic surgery and the like in the semiconductor industry and biotechnology. A micro-motor, a common micro-motion device, can generate small-sized motion by converting electric energy and magnetic energy into mechanical energy, but has high positioning accuracy. Current micro-motors can be divided into two categories: one type is driven by the driving force generated by various fields, including electrostatic micromotors, magnetostatic micromotors, electromagnetic micromotors, direct current and alternating current servo micromotors and the like; one is to convert the material deformation into driving force, including piezoelectric micromotors, shape memory alloy micromotors, magnetostrictive micromotors, etc.

The mainstream electronic cigarette realizes the passive delivery of tobacco juice by passively guiding the liquid storage cotton or the tobacco juice in the liquid storage bin to the heating core mainly through the siphoning action of the oil guide piece (such as the oil guide cotton). This mode can not the manual control tobacco juice to the volume of delivering of core that generates heat, often there is the tobacco juice transport volume not enough or too much the condition, when the efficiency of generating heat of the core that generates heat and the transport volume of tobacco juice mismatch, the dry combustion or the burnt core problem that the core temperature that can appear the tobacco juice transport volume not enough and generate heat too high and lead to, also can appear the tobacco juice transport volume too much and generate heat the insufficient problem of tobacco juice atomization that the core temperature is crossed and lead to the low excessively, the former can appear the flue gas scald the mouth, sensory defects such as sensory peculiar smell, the latter can appear that the cigarette volume diminishes, does not go out the cigarette and even inhales the sensory defect of tobacco juice. In order to solve the above problems, recently, there have been patents which use micro-pumps for active pumping of tobacco smoke, especially piezoelectric micro-pumps for pumping tobacco smoke. Although directional and quantitative pumping of the tobacco liquid can be achieved, there are two major drawbacks: firstly, the piezoelectric micropump is usually hexahedral and relatively large in size (the length and the width are generally several centimeters), and the miniaturization of electronic cigarette products is directly influenced; secondly, need a large amount of external pipelines and interfaces to connect atomizer and tobacco juice stock solution storehouse, directly influenced the integration degree of electron cigarette product, brought the difficulty for equipment and batch production.
