A volatile refined oil for hypnotizing and improving sleep quality is prepared from grass-leaved sweetflag rhizome (60-90 wt.%) and ginger (10-40 wt.%). Its advantages are high effect, and no poison and irritation.

The invention discloses an automatic acupuncture pen which comprises a pen holder, a pen hanger, a positioning head, a through hole, a gear-type rotating acupuncture box, an acupuncture depth controlsystem, a needle inserting and withdrawing system and a magnetic source. The pen hanger and the positioning head are connected at two ends of the pen holder in a threaded manner, the through hole is formed in the bottom end of the pen hanger, the gear-type rotating acupuncture box and the acupuncture depth control system are mounted inside the pen holder and sequentially connected with the positioning head, the needle inserting and withdrawing system is inserted into the gear-type rotating acupuncture box, the gear-type rotating acupuncture box comprises an acupuncture box, a gear-type rotating disk, a gear and an acupuncture box shell, the gear-type rotating disk and the gear are inserted into the acupuncture box, and the acupuncture box shell externally sleeves the acupuncture box. The acupuncture depth control system comprises a first push rod, a second push rod and a connecting rod, wherein the second push rod penetrates the through hole and is connected with the pen hanger, and the connecting rod is positioned between the first push rod and the second push rod. The needle inserting and withdrawing system comprises a transmission rod, a disk and a spring, wherein the disk is fixedly welded in the middle of the transmission rod, and the spring is wound on the transmission rod. The magnetic source is mounted inside the gear-type rotating disk. The automatic acupuncture pen issimple in structure, production cost is reduced, needle inserting depth can be adjusted, and operation and use of doctors are facilitated.

The invention discloses an all-weather fire and smoke real scene simulation training apparatus mainly used for simulating the phenomenon of combustion development of combustible matters in the air of a real fire scene, conducting researches on the development process of fires, training the reaction ability of fire-fighting personnel according to different fires, overcoming the fear, and putting out the fires accurately, effectively, and rapidly. According to the apparatus, various types of fire scenes can be simulated via the adjustment of the flow of solid combustible particles and combustible gas so that various simulation project trainings are realized; a host computer automatic control system is employed to perform safety protection and automatic record and analysis of training data; a combustor employs combustible gas as the fuel so that pollution to the surrounding environment is prevented; and an all-weather high-power automatic igniter is applicable to different weathers, and the training can be normally realized in weathers such as strong wind or heavy rain.

The invention discloses a small-sized portable air brazing welding gun. Air inlets which are communicated are formed on an air mixer, an adjusting valve component is formed by connecting an adjusting hand wheel, a shaft and nuts by screws and is matched with a reducing spring in a spring base, the spring base is arranged in a round nut, and the round and adjusting nuts are connected to the inner wall of a shell of a reducing valve; and a filter I is arranged in a thimble of an air bottle, a filter II and an air needle spring are arranged in an air needle base, a steel needle is also fixed on an air needle with an air needle sealing gasket, one end face of a disc-shaped bowl contacts the steel needle, and the other end of the disc-shaped bowl is matched and assembled with a sealing gasket which is tightly adhered to the spring base. The small-sized portable air brazing welding gun has the advantages that: the complete separation of liquid and air-phase gas is realized by setting two stages of filters, and combustible liquid-phase components cannot enter a gas channel, so that the phenomena of incomplete combustion and red flame are radically prevented; the reducing valve component has the dual functions of pressure adjustment and backfire prevention and can automatically close a flow channel of a gas bottle in case of backfire, so that hazard safety accidents caused by backfireare radically avoided and the safety of the gas bottle is guaranteed at the same time; and the small-sized portable air brazing welding gun is easy to operate, wide in application range, comfortable in handfeel and portable.
