The utility model provides a pump head locking mistaken touch prevention lotion bottle which comprises a lotion bottle body and an infusion pump assembly, the top of the lotion bottle body is spirally connected with a bottle cap, a pressing base is installed above the bottle cap, a rectangular hole is formed in the surface of the top of the pressing base in a penetrating mode, and the bottom of the rectangular hole is provided with an opening. Through cooperative use of a rectangular hole, a limiting plate, a strip-shaped hole, a limiting column and a spring, a pressing head can be conveniently limited and locked when the emulsion bottle main body is not used, so that when a user uses the emulsion bottle, the user pokes the limiting plate to one end of the rectangular hole through fingers to separate the strip-shaped hole from the limiting column, and the user can conveniently use the emulsion bottle. Then the user can downwards press a pressing seat to extract the emulsion, after pressing is completed, the fingers leave the pressing seat, then a limiting plate restores to the original position under the action of a spring, a strip-shaped hole is connected to the outer side of a limiting column in a sleeving mode, and therefore the pressing seat is locked, pressing is blocked, and the emulsion pump is prevented from being touched by the child by mistake; and waste and unnecessary dangers are avoided.

The utility model provides a kind of methanol hydrogen production power generation system for submarine, it is related to methanol hydrogen production power generation technical field, to solve the power of submarine when diving is lower, since liquid hydrogen needs to be stored under ultra-low temperature, and it is more dangerous to store liquid hydrogen and liquid oxygen simultaneously in a submarine, including reformer;Reformer is connected with fuel tank by fuel pump;Reformer is provided with palladium membrane outside;Palladium membrane is connected with burner and hydrogen buffer tank respectively;Burner is connected with oxygen cylinder by pipeline;Hydrogen buffer tank is connected with fuel cell by pipeline;Reaction water storage tank is connected with methanol storage tank by pipeline;Methanol storage tank is connected with fuel tank;Methanol storage tank is connected with fuel tank by metering pump A. Only need to carry methanol as fuel in liquid state at normal temperature, submarine needs to carry high-pressure oxygen or liquid oxygen reaction to produce hydrogen, hydrogen and oxygen generate electricity in fuel cell to supply the electric motor drive of submarine, safe, quiet and efficient.
