affect vision
The most obvious harm of lying down and playing with a mobile phone is that it affects vision, and it is easier to affect unilateral vision. hot mobile phone，Especially after turning off the lights at night, the light will also stimulate the eyes and affect the vision.


damage the skin

Can e-cigarettes be smoked with cigarettes, but not recommended. Excessive smoking can make the human body addicted and cause great harm to the body.


There is no incompatibility between the components contained in electronic cigarettes and those contained in cigarettes, disposable pod ，and smoking together will not produce toxic substances, so electronic cigarettes can be smoked together with cigarettes.


However, because both electronic cigarettes and cigarettes contain a certain amount of nicotine, smoking too much will make the human body addicted, so it is generally not recommended to smoke too much together, but in the process of quitting smoking, E- can also slowly replace cigarettes with cigarettes to achieve smoking cessation the goal of.

First of all, we need to know that although the mobile phone screen is harmful to the eyes, it is not the only factor that causes myopia. display manufacturer，The materials of mobile phone screens are generally divided into OLED and LCD.


In terms of color gamut, OLED screens can display endless colors. Since they are self-illuminating, they are not affected by backlights, and they are more advantageous than LCD screens to display completely black images. In terms of display angle, the OLED screen is much better than the LCD, and the viewing angle of the LCD screen is very small


Having said so many advantages, it also has many disadvantages. For example, in terms of price, it is more than twice as expensive as LCD. Secondly, in terms of technical maturity, LCD is a very traditional display, and its production maturity is far superior to OLED. The display speed of OLED is also not as fast as LCD. Moreover, the OLED screen will flicker, which is an inherent flaw. The lower the brightness, the faster the flicker.


At the end of the analysis, the OLED screen is definitely more harmful to the eyes than the LCD screen. Just a single stroboscopic flicker is very harmful to the eyes. The OLED screen will always feel uncomfortable for the eyes after using it for a long time. Instead of discussing which screen is more harmful to the eyes, it is better to find the reason from yourself and reduce the use time of the mobile phone, so as to avoid the damage caused by the mobile phone

Dynamic headphones are the most common and common type of headphones. Its driver unit is basically a small dynamic speaker. Custom Headphones，The voice coil in the permanent magnet field drives the diaphragm to which it is attached. Driven by the signal current, the coil drives the diaphragm to sound.


Most of the dynamic headphones can be driven by the headphone output on the audio, which is reliable and durable, relatively easy to manufacture, has low distortion and wide frequency response. The disadvantage is that the efficiency is relatively low.


moving iron
Electromagnets are used to generate alternating magnetic fields. The vibrating part is a piece of iron suspended in front of the electromagnet. When the signal passes through the electromagnet, the electromagnetic field of the electromagnet changes, which causes the iron plate to vibrate. The advantages are long service life and high efficiency. The disadvantage is that the distortion is large and the frequency response is narrow. Often used in early telephone handsets.

cob light source: a high-efficiency integrated surface light source technology in which the LED chip is directly attached to a high-reflectivity mirror metal substrate.
LED light source: It integrates computer technology, network communication technology, image processing technology, embedded control technology, etc., so it is also a digital information product.

Different advantages
cob light source: It is convenient for the secondary optics of the product to improve the lighting quality; cob led display，it is simple to install and easy to use, reduces the difficulty of lamp design, and saves the cost of lamp processing and subsequent maintenance.
LED light source: low heat, miniaturization, short response time, etc., all of which make LED light source have great advantages and create favorable conditions for application in actual production and life.

Different light sources
cob light source: high color rendering, uniform light emission, no light spots, healthy and environmentally friendly.
LED light source: It can be used continuously for up to 100,000 hours. In the future, the application of LED light source in the lighting field will also become mainstream.

The pod can be injected with e-liquid, so what is the pod? Simply put, a pod is what separates the pod from the pod. When the pod is complete, best disposable vape，we inject the pod into the pod again for use. .


1. Reusable. This is very important. You don't need to buy a new pod after the pod has finished smoking the e-cigarette. You can fill the pods multiple times, which greatly reduces the cost. Compared with the obtained data, the cost is reduced by about 70%.


2. Simple operation. The fuel tank has reserved a fuel port. The entire oil filling process requires only three simple steps: remove the plug, add oil, and put the plug back in one at a time.


3. The choice of taste is flexible. Since the oil filling tank is self-filling, the oil filling amount can be controlled by itself. You can switch to other flavors after smoking to keep it fresh.

First, the point light source is small in size and light in weight, and can be used with a variety of lamps, which is not available in other lamps.


Second, the led point light source has good environmental protection. Even if it is discarded, it can be recycled, which is environmentally friendly and saves resources.


3. The led point light source has good safety and stability. Under the same conditions, compared with the traditional light source, the light decay of the point light source is small, which can be used for a long time and can withstand frequent switching.


Fourth, the point light source has good directionality, and can emit light in one direction, directly irradiating the surface of the irradiated object, and the utilization rate is high.

Plastic items need to be protected from sunlight during use, as do all plastic items. If plastic products are used outdoors in strong sunlight, stabilizers such as UV absorbers should be added to uncooked injection molding raw materials to prevent simple fading of plastic products when the solid is mild.


The stability of the dyes used to make plastics determines how much your product will fade. Therefore, plastic manufacturing ， when determining the colorant, the high temperature resistance of the colorant should be considered.


Some plastic products have poor acid and alkali resistance, such as molybdenum-chromium red, which is immune to dilute acid, but sensitive to alkali, while cadmium yellow is not acid-resistant. These two pigments and phenolic resins have a strong reducing effect on some colorants and affect the resistance of the colorants. Warm, weather resistant and colorfast.
