Problems solved by technology

[0002] In the current electrical products in our country, conventional electrical cabinet doors only use door locks to close the door, so usually in the process of use, especially when in a hurry, just unlock the lock, pull the door open, and take out the required Items, often forget to close the opened door, because the open door occupies a certain space, which brings some troubles to daily life, such as: the corners of the door are generally sharp, which will cause harm to people walking indoors Injury, especially for children, is a greater threat to safety. Moreover, because it is an electrical appliance such as a refrigerator, since the door is not closed, the refrigeration compressor will always be in working condition. Working for a long time will cause the compressor to overheat, thus Burn out the compressor and damage electrical products

Or after taking out the required items during use, even if you remember to close the door, you still close the door with both hands. Due to the uncertain force, the electrical cabinet door will make a "bang" sound when it is closed, causing the door and The vibration of electrical appliances not only has a certain impact on daily life, but also causes unnecessary damage to doors and electrical appliances for a long time, reducing the service life of electrical appliances
