The beneficial effect of this utility model is that it integrates explosion-proof pressure relief and oil level observation functions into one unit, enabling both pressure safety release and oil level monitoring, thereby reducing equipment complexity and maintenance costs, and providing a better solution for the safe and stable operation of capacitive voltage transformers.

The utility model discloses a quick plug type crankcase ventilation pipe, which comprises a ventilation pipe body and a quick plug connector, wherein the ventilation pipe body is made of nylon material and is used for connecting with a crankcase; one end of the quick plug connector is fixedly connected with the ventilation pipe body as a whole; and the other end of the quick plug connector is used for forming a quick plug structure with an engine bulb connector. The quick plug type crankcase ventilation pipe is made of conventional nylon material, thereby avoiding leakage risk. The one end of the DC type quick plug connector and the ventilation pipe body made of nylon material are fixedly connected as a whole by using a normal temperature bamboo joint press fitting process. The other end of the quick plug connector can directly form a quick plug type assembly with the engine connector. Compared with the assembly mode of the mainstream rubber pipe plus clamp in the market, the utility model can reduce assembly time on the basis of solving the leakage problem, thereby making the assembly more efficient, more reliable and more convenient in after-sales service.

This invention discloses a low-voltage wiring harness technology for vehicle front doors, specifically a structure for easy assembly and maintenance of a low-voltage wiring harness for vehicle front doors. The structure includes: a main front door wiring harness; at least one functional branch wiring harness assembly; and at least one quick-connect connector assembly. The quick-connect connector assembly includes a detachably connectable male connector terminal and a female connector terminal. The male connector terminal is provided with conductive contact terminals and is fixedly connected to the functional branch wiring harness assembly. The female connector terminal is disposed on the main front door wiring harness, thereby enabling the functional branch wiring harness assembly and the main front door wiring harness to form a modular connection. This invention employs a modular branch design combined with a foolproof quick-connect connector, completely changing the traditional overall binding mode. Assembly personnel can quickly connect the harness based on clear markings and the foolproof structure, significantly simplifying the assembly process and effectively reducing the probability of incorrect or missing connections.

This utility model relates to a head massager, comprising a shell and a rear shell. A massage assembly is located at the front of the shell, and an essential oil assembly is located in the middle of the massage assembly. A light panel assembly, a drive assembly, a circuit board, and a rechargeable battery are located at the rear of the shell. The massage assembly includes multiple sets of massage rods spaced apart from each other, a flexible cover, a support, a swing seat, and a track gear composite component. The front of the swing seat is fastened to the rear of the massage rod. A spherical massage head is located at the front end of the massage rod, and a ball is located at the rear of the swing seat.
