Buying skills of electric mosquito swatter

When purchasing an electric mosquito swatter, first, pay attention to whether there is information such as the implementation standard number, production date, factory address, and manufacturer's phone number on the outer packaging. Second, pay attention to whether there is a "lightning" danger sign or a "dangerous high voltage" warning on the electric mosquito swatter. 3. Check whether the instruction manual includes that the appliance should be kept away from children and cannot be used in places where flammable gas or explosive dust may exist, and whether there is a detailed description of the cleaning method, cycle and anti-leakage measures. If "lightning" is used Whether the flag has a detailed explanation of its meaning, etc. A good quality electric mosquito swatter can be identified by observing the handle, power grid and related signs. Genuine electric mosquito swatter handles are mostly made of engineering plastics, with good gloss; while defective products are often made of recycled plastic secondary processing, which not only has burrs, but also has a high possibility of breaking. The power grid of a good-quality electric mosquito swatter is generally a three-layer structure, and the distance between adjacent layers is large, and the power grid seems to be relatively thick. At the same time, the electric mosquito swatters produced by regular manufacturers are marked with the product name, operation method, factory address, factory name and other information, and the product also comes with a manual.

How to choose a flashlight

With the vigorous development of the power industry, outdoor flashlights play a very important role in our outdoor sports because of their high-precision brightness, long battery life and sturdy materials. So, how to choose an outdoor flashlight? 1. See where you want to use it, such as night riding, night fishing, outdoor camping, caving, patrolling, etc. 2. Look at the aperture, the aperture of a good LED flashlight is a uniform circle, and the light spot of a bad LED flashlight is divided into yellow and blue, and the distribution is uneven. Look at the brightness, a good LED flashlight has high brightness and slow decay. 3. Look at the battery, there are ordinary batteries, there are lithium batteries. Although the lithium battery can be charged, its service life is short, about 2 years, and the LED life is about 10 years, which can be selected according to the actual situation. Look at the light bulb. The light bulb went out, and it was difficult to distinguish good from bad with the naked eye. You can see the consistency when the bulb is on. 4. It looks waterproof. A good LED flashlight has waterproof function and good shock resistance, that is, it is anti-fall. Looking at the appearance, you will see this more clearly than I do, so I won't say much. I chose an aluminum alloy casing, which is beautiful and elegant. 5. Basic requirements for household flashlights: practical, cost-effective, comfortable operation, moderate brightness, convenient battery replacement, and easy maintenance; I personally suggest that if you use it at home, it is more appropriate to choose a domestic flashlight. The key is to choose a product with better quality, a big brand with certain professional experience and perfect after-sales service

Are electric mosquito swatters safe?

Won't. Electric mosquito swatters are about a few hundred volts. When the human body touches the positive and negative terminals at the same time, there will be obvious electric shock, but it is not dangerous, because its internal resistance is very large, and the voltage will drop immediately after touching the human body. The main advantages of the electric mosquito swatter: triple voltage, the electric mosquito swatter adopts the first triple voltage rectifier and circuit, the instantaneous output voltage is as high as 2500V, and the mosquito repelling effect is particularly good. No electric numbness, the electric mosquito swatter can kill the mosquitoes that are sucking blood, and it is harmless to the human body. No leakage. The electric mosquito swatter has a special three-layer mesh structure, which makes it easy for mosquitoes and flies to enter the net without slipping through the net. Precautions for electric mosquito swatter: Press the switch when attacking mosquitoes and flies, wave the mosquito swatter, and the mosquitoes and flies will be killed by light touch. Mosquito swatters killed by the net surface, please shake the net to make it fall off, do not rinse with water to prevent short circuit. The climate is humid, the mosquito swatter may absorb moisture without high pressure or become low pressure, and the killing effect will decrease. You should use a hair dryer to dry it in time or dry it in the sun, and the effect of the mosquito swatter will automatically recover. The electric mosquito swatter works on DC high voltage and will generate sparks of a certain intensity. Therefore, it is strictly forbidden to use and overhaul it in places full of flammable gases, and avoid touching the high-voltage power grid with hands or conductive metal rods when electrified. to prevent accidents. Electric mosquito swatters are not toys and should not be used by children.

Is the desk lamp as bright as possible?

01Is the brighter the desk lamp, the better? To answer first, no. In the past, we all know that we should not focus on using our eyes in a dimly lit environment, which can easily lead to myopia. Therefore, many parents go to the other extreme when choosing desk lamps, pursuing high-brightness lighting effects. The lights used by children to read and write are too bright, and this situation will also hurt the eyes. Some people may be puzzled, why is the light too bright to hurt the eyes? This is because when the human eye encounters strong light stimulation, the pupil will shrink to reduce the amount of light entering the eye. If the eye is used in an excessively bright light environment for a long time, the pupil will continue to shrink, causing the ciliary muscle to over-regulate. Cause eye fatigue, pain, and even dizziness. Everyone should have encountered a phenomenon in life. When you look directly at the light source, you will feel that there is a bright spot in front of your eyes. Even if you remove the line of sight, the bright spot will move along with it, causing temporary blurred vision. This is the macular area of ​​the retina. A "visual afterimage" produced by strong light stimulation. When we use our eyes under such strong light for a long time, it will cause damage to the retina (especially the macula), resulting in decreased visual sensitivity and permanent decline. In addition, adolescents are in the stage of growth and development. Like other organs in the body, the eyes are not yet fully mature and are easily changed by excessive stimulation by external factors. The eyes are stimulated by strong light for a long time, which will cause changes in the function of the eyeball, which will prevent the eyes from developing normally, resulting in the formation of myopia.
