BRIEF SUMMARY
DESCRIPTION



Technical field

The present invention relates to a fuming or smoke-emitting device to simulate the smoke exhausted from the model steam locomotive and the model ship, etc. And more particularly, it is suitable for use on a model steam locomotive of railway. The railway model is different from toys, and its reduced scale and the method of operation are, to some degree, internationally standardized. As for the reduced scale, except minor ones, the two reduced scales are mainly adopted; one is refered to HO-gauge whose reduced scale of model train is about 1/80, another is refered to N-gauge whose reduced scale of model train is about 1/160. As the model locomotive recently tends to become small, N-gauge has been prevailing. The method of operation mostly used is the remote control to supply electric power in the rail from the transformer, from which, through the wheels, the motor gets the driving power. In the smoking state of the fuming device, it is required to simulate the smoke exhausted from the actual smoke locomotive. Although it may be possible to simulate the smoking state regardless of the size of the device and its production cost, the space to load the fuming device is, in actual fact, very restricted due to the reduction of the locomotive and other driving devices. Therefore it is required to reduce the size of the fuming device as much as possible. These requirements are critical. It seems to be impossible to make a small device by means of any mechanical design. So the technical problem is to answer the both requirements; that is, precise simulation of smoking state and reduction of the fuming device.


Background art

Any fuming method, tried so far, uses smoke produced by burning oil, and there are two general methods for exhausting the produced smoke, namely one has recourse to the mechanical device for burning and another has recourse to an air blower. In the former method, the smoking state has not been performed satisfactorily and the latter method requires an exaggerated device. However, one couldn't help compromising in using them to some extent. Some types of fuming devices are sold now. Among the products appeared in the "Tetsudo Mokei Shumi (Hobby of the Railway Model)", which is the Japanese special book of railway model, typical one is the product of West Germany which is the example of the specially designed device for burning. In the following, the explanation of the device is cited and summarized. "In West Germany, SEUTE sells some kinds of fuming devices. In Japan, the devices of product-numbers 99 and/or 100 for HO-gauge are familiar. Inner structure is very simple; there stands a thin steam pipe like an injection-needle in its center, and the upper part of it, about 7 mm long, is a heater with thin Nichrome wire wound. The oil for burning is stored in the botton of the device and the oil is pumped due to capillarity action in the pipe, then heated and evaporated by the heater and ejected upward. This process is made intermittently, so the white smoke continues to eject so long as the oil exists." But the following comments are made that the smoking state doesn't resemble and the amount of the smoke is too little and that the power of ejection is too little. The size of the device is relatively small, but the burning method requires the device to be set vertically, so the model locomotives available to the device are limited. Another typical product is one of Japan. In the following, the explanation of the device is cited and summarized. "A fuming device whose chamber for making smoke and blower are separated, and is designed for tender. That the amount of smoke is enough and the smoking state varies in accordance with the speed of the locomotive is characteristic." The device is limited to some particular locomotives for use, however, the smoking state is highly estimated.
