Electronic cigarettes are mainly composed of three parts: a pipe containing nicotine solution, an evaporation device and a battery. The atomizer is powered by a battery rod, which can convert the liquid nicotine in the cartridge into mist, so that the user has a smoking-like feeling when inhaling, and realizes "puffing the cloud". It can add various flavors of spices such as chocolate and mint to the pipe according to personal preference.

The internal structure of the cigarette rod uses the same basic components: a light PCBA board, rechargeable batteries, various electronic circuits.
Most electronic cigarettes use lithium-ion and secondary battery power components. Battery life depends on battery type and size, usage and operating environment. And there are many different types of battery chargers to choose from, such as socket direct charging, car chargers, and USB interface chargers. The battery is the largest component of an e-cigarette.
Some e-cigarettes use an electronic airflow sensor to activate the heating element, which activates the battery circuit upon inhalation. Whereas manual induction requires the user to press a button and then smoke. Pneumatic is easy to use, the manual circuit is relatively more stable than the pneumatic, and the smoke output is better than the pneumatic. With the development of hardware and software, some manufacturers have begun to develop fully automatic machines to manufacture electronic cigarettes, eliminating the use of manual wiring, welding or electronics to achieve higher safety and reliability.
Decompression valve decompression process
A pressure relief valve is a special device that automatically reduces the working pressure on the line by reducing the higher water pressure in the line before the valve to the level required by the line after the valve. Pressure relief valve is widely used in high-rise buildings, urban water supply pipe network pressure over the area, mines and other occasions to ensure that the water supply system water points to obtain appropriate service pressure and flow. In view of the water loss rate and the degree of waste is almost proportional to the size of the water supply system pressure, the valve has to improve the system operating conditions and potential water savings, YK43XF gas valve according to statistics its water saving effect of about 30% . Many types of pressure relief valve structure, the previous common thin-film, such as the spring-piston. The basic principle of the valve is to reduce the water pressure by the local resistance of the flow channel in the valve. The range of the water pressure drop is automatically adjusted by the pressure difference between the inlet and outlet of the film or piston connected with the valve flap. Since 2007, there have been some new type of pressure reducing valve, YK43F stainless steel gas pressure reducing valve, such as constant pressure reducing valve. Constant pressure than the principle of decompression is the use of valve body floating piston hydraulic ratio control, import and export side decompression ratio and the import and export of piston area ratio is inversely proportional. This valve works smoothly without vibration; there is no spring in the valve body, so there is no spring rust, metal fatigue failure considerations; good sealing performance without leakage, so both under pressure (water flow) and then the static pressure 0 o'clock); Especially in the decompression does not affect the water flow. When the calibrator is in non-working state, the compressed air input by the air source is filtered by the filter 1 and enters into the A chamber and the positive chamber. The main spool 19 presses against the valve seat under the pressure of the spring 20 and the air source to disconnect the A and B chambers. The air entering chamber A flows through ports 12 to F through the valve ports (aka valves), and then depressurizes through the constant orifice 13 to enter compartments G and D, respectively. Since the diaphragm 8 is not yet energized, the distance between the baffle plate 5 and the nozzle 4 is large, the flow resistance of the gas flowing out of the nozzle 4 is small, the pressures in the G and D chambers are low, and the diaphragm 3 and 15 Keep the original position. The trace gases entering the chamber are mainly discharged from the exhaust port through the valve chamber 2 through chamber B and the other portion is exhausted from the output port. At this moment, there is no air flow output at the output port. It is necessary for the nozzle baffle device to work to discharge the trace gas when it is discharged from the nozzle. Because it is a reactive gas consumption, it is desirable that the consumption be as small as possible. The basic performance (1) pressure regulating range: It refers to the output pressure of the relief valve P2 adjustable range, within the scope of the required pressure relief valve to the required accuracy. Regulating the pressure range and the main spring stiffness. (2) Pressure characteristics: It refers to the flow rate g is set value, due to input pressure fluctuations caused by the output pressure fluctuations. The smaller the output pressure fluctuation, the better the characteristics of the pressure reducing valve. The output pressure must be lower than the input pressure - the setting will not substantially change with the input pressure. (3) flow characteristics: It refers to the input pressure - timing, the output pressure with the output flow g changes in the holding capacity. When the flow rate g changes, the output pressure changes as small as possible. The lower the general output pressure, the smaller it fluctuates as the output flow changes.
