Range hoods are a must-have device in the kitchen and are closely related to everyday life. How to purchase a range hood with ideal performance and price to keep the indoor environment clean and comfortable is a concern for every consumer. Pay attention to the following points when purchasing:
1. Structure: It is more stable to choose to install the fixed equipment. Usually, the range hood should be fixed on the wall. Therefore, in addition to the keys, holes, hooks, etc., it is required to have a suitable device to fix it on the wall. At the same time, the device should be made of metal that is not easily moved or deformed. So as not to cause loose use of the fixed equipment for a long time.
2. Marking: The name, trademark, rated voltage, rated input power and certification mark of the model, manufacturer or distributor should be indicated on the range hood. If the range hood has an illumination bulb, the maximum power of the bulb used should also be indicated on or near the lamp holder. At the same time, each range hood is equipped with a Chinese instruction manual to help consumers use it safely. In the instruction manual, the minimum distance between the range hood and the support surface of the cooking utensils on the stove should be marked, and the range hood should be directly prohibited from baking. The purchase should be clearly recognized.
3. Choose a good after-sales dealer and manufacturer. Under normal circumstances, you should purchase well-known brand range hoods. These product manufacturers have high-quality service teams, advanced production technology and production capacity, which not only can produce better quality range hood products, but also provide high quality. After-sales service, relieve the worries of using the range hood. It is difficult to solve problems in the process of using the product.
4. Consumers should choose range hood products according to their own consumption power. At the time of purchase, you can feel the leaking air around the range hood by hand. The air volume is not big. If there is no air leakage and the large air volume indicates that the range hood has strong ability to smoke, you can also directly feel the noise of the range hood. The size, especially the frontal noise, and the touch of the casing to see if the vibration, quiet, smooth running range hood is the user's first choice.

Light Emitting Diode F5 In-line
1. Welding prerequisite: (The solder joint must be at least 2mm away from the resin root)
Dip soldering: Please complete the soldering once within 5 seconds at 260°C to prevent the resin from being immersed in the tin bath.
Soldering iron: Use a 30W soldering iron with the tip temperature not higher than 350℃, and the soldering can be completed once within 5 seconds.
Do not apply external force to the product during soldering. Pay attention to prevent the LED pins from being corroded or discolored, otherwise it will cause soldering difficulties. It is recommended to use it as soon as possible.
2. Use attention:
Lead forming must be completed before soldering, and the spacing between the device holes on the circuit board should be consistent with the electrode pins.
If the product is cut under high temperature, it will be defective. Please cut the lead at room temperature.
Before the soldering temperature returns to normal, the LED must be protected from any vibration or external force.
3. Electrostatic protection:
In-line LED
High-brightness blue, green, and white products are sensitive to static electricity. Please be aware that the surge of static electricity will damage or destroy the product. Please use a conductive pad to ground the task table in contact with the product; the tip of the soldering iron must be grounded. To be grounded; it is recommended to use an ion generator.
4. Cleaning:
Special care must be taken when cleaning the gel with chemicals. Some chemicals can damage the surface of the gel and cause discoloration, such as trichloroethylene and acetone. It can be wiped and dipped in ethanol, and the time does not exceed 3 minutes at room temperature.
