The present application belongs to the technical field of water storage and waterway system, and particularly relates to a motor home and a hot water system thereof. In order to solve the problems of non-continuous hot water supply and slow heating speed of the existing hot water system of the motor home, the present application generates hot water by any one of the heating modes of heating through a heat exchange device, heating through a heat preservation water storage device and heating through an electric heating device when the vehicle is started, and generates hot water by heating through the electric heating device when the vehicle is not started. The present application can generate hot water fast and continuously in any state of the motor home.

The utility model discloses a novel steaming bed which comprises a bed body, a water tank and a steam generator, a steam chamber communicated with the steam generator is arranged on the upper portion of the bed body, a porous screen plate is arranged on the steam chamber, and at least one containing cavity is arranged on the porous screen plate. One end of the steam generator is connected with the water tank through a water inlet pipe, and at least one exhaust pipe extending into the steam chamber is arranged at the other end of the steam generator; and a return pipe is arranged at the bottom of the steam chamber and is connected to the water tank. The independent steam chamber is arranged in the bed body, high-temperature steam is directly provided for the steam chamber through the steam generator, the high-temperature steam is utilized to enable the traditional Chinese medicine bags in the porous screen plate and the containing cavity to be evenly heated and not prone to mildewing, and the independent external water tank is adopted to supply water to the steam generator to generate steam. Therefore, the water can be heated according to the required amount of steam, and the water heater can be started and stopped immediately, so that the temperature rise is quick, and excessive energy waste is avoided.

The utility model relates to the technical field of steam preparation, in particular to a steam generator and a steam generation system. The steam generator comprises a shell, a second heat exchange tube and a preheating unit; the shell is provided with a refrigerant inlet, a refrigerant outlet and a steam outlet; the second heat exchange pipe is connected between the refrigerant inlet and the refrigerant outlet, and the interior of the second heat exchange pipe is used for introducing a high-temperature refrigerant to exchange heat with water stored in the shell; the preheating unit is arranged at the top in the shell and comprises a first heat exchange pipe and a water supplementing pipe fitting which are connected in a heat exchange mode, the first heat exchange pipe is connected between the refrigerant inlet and the refrigerant outlet and used for introducing a high-temperature refrigerant and supplementing water in the water supplementing pipe fitting to conduct heat exchange, and a water inlet of the water supplementing pipe fitting extends out of the shell. A water outlet of the water supplementing pipe fitting is located in the shell and can supplement water in the shell. According to the steam generator, the heat exchange efficiency is remarkably improved, and then the steam preparation efficiency is improved.

This invention provides a cobalamin derivative, its preparation method, and its application in the synthesis of arsenopyrine, relating to the field of heterocyclic compounds, and more specifically to the field of arsenopyrine synthesis technology. This cobalamin derivative is prepared by linking a 3-amino-3-carboxypropyl (ACP) group to the cobalt atom of cobalamin (CbI), and protecting the 3-amino-3-carboxypropyl group with a 9-fluorenemethoxycarbonyl (Fmoc) and a tert-butyl (tBu) group.
