Various indexes of the automobile traveling data recorder equipment product can be rapidly tested within 180 seconds, whether the indexes are normal or not can be conveniently positioned, and a scheme which is simple, convenient, low in cost and capable of rapidly testing the product quality is provided.

This utility model discloses a portable essential oil massage device, belonging to the technical field of massage therapy devices, which solves the problems of inconvenient essential oil delivery and limited functionality in existing massage devices. The portable essential oil massage device includes a main body and a replaceable massage head. The bottom center of the main body has an insertion hole with two axial protrusions, and an essential oil chamber inside to hold an essential oil bottle. An oil guide tube passes through the top cap of the essential oil bottle and connects to a miniature solenoid valve. A miniature vibration motor with its axis perpendicular to the bottom surface is fixedly installed inside the main body via a shock-absorbing silicone pad. The top insert of the replaceable massage head has a groove matching the protrusions and an oil guide cavity connecting to the bottom micro-hole. The bottom surface of the main body and the top surface of the massage head are magnetically connected by an annular magnetic clasp. Through the synergistic action of the vibration motor and the magnetic insertion structure, the device achieves rapid massage head replacement, precise essential oil delivery, and multi-dimensional vibration massage functions. The unique effects of aromatic essential oils, combined with massage, accelerate blood circulation, promote skin absorption, and enhance the overall effect.

The application discloses a liquid lithium-lead self-cooling cladding with low MHD pressure drop, and relates to the technical field of fusion reactor engineering; comprising: an outer cladding, which comprises an outer cladding circumferential arc-shaped main flow channel; the outer cladding circumferential arc-shaped main flow channel comprises a first wall region flow channel and a tritium breeding zone flow channel arranged in sequence from inside to outside along the radial direction; an inner cladding, which comprises an inner cladding circumferential arc-shaped main flow channel; wherein the flow direction of the outer cladding circumferential arc-shaped main flow channel and the inner cladding circumferential arc-shaped main flow channel is parallel or tends to be parallel to the magnetic line direction of the circumferential magnetic field of the fusion reactor; the outer cladding circumferential arc-shaped main flow channel and the inner cladding circumferential arc-shaped main flow channel are provided with flow channel inserts at the turning positions of the inlet and the outlet; and the polar height a of the outer cladding circumferential arc-shaped main flow channel and the inner cladding circumferential arc-shaped main flow channel is greater than the radial width b; the cladding has the advantages of low MHD pressure drop, simple structure, small processing difficulty and easy realization in engineering.
