This may require a special plug. Some plugs have only metal heads and the lower half is covered with plastic, such as As long as the structure is clever, the sealing ring is made of hydrophobic material, and the water on the pin is wiped off during the insertion of the sealing cavity, and it can be insulated from water when inserted 2/3. Continue to insert it deeper until the retaining spring does not bottom out, and the phase line is not connected. When it is basically inserted to the bottom, the linkage structure connects the circuit and "electrical connection" occurs. This may be feasible, but I don't know how durable it is.

This is patented, OK

The application for a utility model is relatively simple and easy to pass compared to an invention patent. Huawei gets its tens of thousands of patents every year in this way. In fact, if you look closely at the technology of many utility models, it's just that simple. Most of them are just for show. After all, those companies have requirements and reward and punishment measures for the number of patents submitted for research and development, but they don't give much thought to quality. As long as it can pass the review, it's fine (in principle, if there is no identical application, it can generally be passed. Of course, they will spend money to find a professional application agency to assist with the format and process).

I wonder if the designer has considered the unexpected situation that the relay contacts stick together and the output is uncontrolled? After all, when used in a socket, the type and power of the electrical appliances cannot be restricted. For example, a capacitive load can easily generate a large surge current (tens of times the normal working current) and cause the contacts to melt and stick together. At this time, the uninformed user is still operating the relay in water. Who is responsible?

Thank you! I’ll take a closer look.

The value of a patent varies greatly. It may be worth hundreds of millions, or it may be worthless. For example: I once said in the power supply section that if you make a pancake pan into a triangle, you can apply for a patent, and it will be 100% approved. But is such a patent valuable?

The nRF24L01 wireless transmission module can achieve one-to-many, many-to-one, and many-to-many. According to the characteristics of the nRF24L01 chip, it can achieve that the data will not affect each other when multiple devices are running at the same time. This involves the pairing problem. When I did this, I thought of changing the receiving and sending addresses in real time. This method is indeed usable, especially in one-to-many situations, but it is not very good in many-to-one situations, and there will be data loss. Therefore, for many-to-one, it is recommended to use multi-channel receiving data, and combined with my method, I believe it can be solved. I didn't do that part. If someone has done it, I hope you can share it for learning. After all, OPEN SOURCE is a good method.

    In another demonstration area decorated as a bathroom, the staff turned on the shower head and sprayed hot water directly onto the socket where the water heater was plugged in. The water heater was not affected by the water and continued to work normally. The staff said that this socket is not only waterproof, but also solves the three major safety problems of "leakage, short circuit, and arc" that have long existed in traditional exposed electrical connection technology. Even if the electrical plug is unplugged in a space with natural gas reaching an explosive concentration, there will be no sparks caused by metal collision and no explosion.
