Q1: Why are there fewer and fewer large vape players?
First of all, policies ban online platforms from selling all e-cigarette-related items. Due to operational difficulties, there are fewer physical stores. As a result, they fail to replenish reserves. And the large vapes need the vapers to learn more skills to use them. While small vapes are more convenient to use, simpler in structure, and can be purchased on many channels, the market has basically sought solutions from e-cigarettes.
Q2: Can e-cigarettes pass the plane security check?
It is fine to bring small e-cigarettes and e-liquid not exceeding 100ml to pass the security check. But it is only allowed to carry, can't vape on the plane. Lithium batteries with energy not exceeding 100wh (watt-hours) can be carried. Those with energy exceeding 100wh but not exceeding 16wh need to be approved by the airline. Even so, you cannot bring more than two pieces. Lithium batteries with energy exceeding 160wh cannot be carried or mailed. Therefore, we must check the battery capacity before boarding the plane. However, if the security check is upgraded during a special event, a bottle of e-cigarettes may not be allowed to be carried. But the small e-cigarettes currently on the market are basically approved.
Q3: Why does the throat dry out after Vaping too much?
The main component of e-liquid is vegetable glycerin. Glycerin is water-absorbing. When atomized at high temperatures, it will take away the moisture in the mouth. Naturally, the tongue and throat will feel dry. Vegetable glycerin (VG) and propylene glycol (PG) are highly water-absorbing substances. The ability to secrete saliva in each person's mouth is different. Some people have strong secretion ability, so they don't feel a dry mouth. PG and VG are healthy food additives. Essences and fragrances mainly provide various flavors, and nicotine provides addiction relief and throat hit.
Q4: Is secondhand vape a thing?
E-cigarette vapor is mainly atomized from vegetable glycerin, which is basically harmless to the human body. And e-cigarette vapor does not contain the main harmful substances of second-hand smoke such as tar and carbon monoxide.
However, it is not 100% safe. It is also up to the e-liquid you used. If your e-liquid contains nicotine, ultrafine chemistry materials, or various other toxins, including several cancer-causing agents. It also will do harm to others. So, you need to pay attention to the e-liquid you used. And don't vape indoors.
Q5: Can vapes set off smoke alarms?
Yes. Vapes can set off smoke alarms. Smoke alarms test the concentration of inhalable particulate matter in the air. It is also what we often call PM2.5. When the concentration of PM2.5 in the air exceeds the standard, the smoke alarm will alarm. Although the aerosol vapor of electronic cigarettes is not produced by combustion, also triggers the smoke alarm.
At present, the TIF smoke sensor in the United States prevents fire by monitoring the concentration of smoke. The ion smoke sensor is usually used inside the smoke alarm. It is an advanced technology, stable and reliable sensor. It is widely used in all kinds of fire alarm systems. Its performance is far better than gas-sensitive resistor fire alarms.
A smoke sensor is used to detect whether there is smoke and the concentration of smoke in the environment. Such as detecting thick smoke in a fire. When the smoke detector encounters smoke or certain specific gases, its internal resistance changes. When reaching an analog value, it will be generated to control it.
The smoke sensor uses the principle that the smoke-sensitive element is affected by the smoke (mainly combustible particles) concentration to change the resistance value to send an analog signal corresponding to the smoke concentration to the host. Smoke sensors mainly include ion smoke sensors, photoelectric smoke sensors, and gas-sensitive smoke sensors.
Among them, ion detectors form charged particles (ions) after the ionization of uncharged particles. Therefore, they are called ion smoke detectors. It is suitable for the detection of open fires.
Photoelectric Smoke Sensor
The detection chamber of the photoelectric smoke sensor is equipped with an optical sensor. When smoke enters the detection chamber, it will block the emission of light and cause scattering. The photoelectric receiver will receive the signal that changes due to light scattering. Then a change in the current signal is produced.
Gas-sensitive smoke sensor
The gas-sensitive smoke sensor is a sensor that detects a specific gas. It mainly includes semiconductor gas sensors, contact combustion gas sensors, and electrochemical gas sensors. And the semiconductor gas sensors are the most used.
Its applications mainly include the detection of carbon monoxide gas, gas, Freon (R11, R12), ethanol in exhaled breath, bad breath in the human oral cavity, etc.
The information related to the concentration is converted into electrical signals. And the information related to the existence of the gas to be measured in the environment can be obtained. According to the strength of these electrical signals, the detection, monitoring, and alarm can be carried out. It can also communicate with the computer through the interface circuit Composition of automatic detection, control, and alarm system.
American TIF sensor
Commonly used in gas leakage devices in homes and factories, and suitable for the detection of liquefied petroleum gas, butane, propane, methane, alcohol, hydrogen, smoke, etc.
Q6: Are e-cigarettes addictive?
The addictive ingredients in traditional cigarettes are nicotine and tar. The e-cigarettes do not contain tar. But to restore the irritation to the throat, e-cigarettes add an appropriate amount of nicotine. So e-cigarettes will produce a certain amount of addiction. If you vape it with nicotine-containing e-liquid, it is addictive.
Q7: Are e-cigarettes to blame for the "popcorn" lungs reported in the US?
For bronchiolitis obliterans (also commonly known as popcorn lung), vitamin E acetate is the culprit. All EVALI cases contain vitamin E acetate in the patient's lung fluid. There are many reasons that will cause vitamin E acetate. One is a multiple drug overdose, one is a fungal infection, and the other may be a bacterial infection of the lungs. U.S. researchers tested lung fluid from 99 healthy people, including 18 e-cigarette users. The result is no one detected vitamin E acetate. It was not found in any of the nicotine-containing e-liquids they tested for Vitamin E acetate, so the answer is no.
Q8: The British news media reported that switching from cigarettes to e-cigarettes can help improve heart health. Is this an exaggeration or is it true?
According to professor Siegel of the UK, there are many causes of heart disease. It is including diet, alcoholism, and lifestyle habits. However, Professor Siegel questioned the research project of Jacob George. A professor of cardiovascular medicine and therapeutics at the University of Dundee. (By switching from cigarettes to e-cigarettes, it was found that the cardiovascular index increased by an average of 1.5 percentage points within a month. And combined with other research results, every 1 percentage point increase in vascular function will reduce the incidence of cardiovascular disease by 13% "). Because the study not only did not prove that vaping will increase the cholesterol level of the observed subjects. But it also didn't clearly exclude possible causes other than e-cigarettes. Switching from cigarettes to e-cigarettes can help improve heart health, which remains to be studied.
Q9: Do e-cigarettes contain formaldehyde?
Not all produce formaldehyde, but some gamer-level devices that are admired by e-cigarette users will produce formaldehyde and other harmful substances. The principle of formaldehyde generation: 8 kinds of volatile carbonyl compounds produced by the cracking of glycerol and propylene glycol. The main solvents in electronic cigarettes are glycerol and propylene glycol. The calorific value of some is not enough to produce formaldehyde.
