Description

Discontinuous smoke production device in a miniature steam locomotive}

The present invention relates to an intermittent smoke generator of a model steam locomotive, which is characterized in that regular and modest discharge of smoke is possible without a smoke tail.

A model is a dictionary, which is reduced, enlarged, or reproduced to a real size in the same or similar shape as the real, that is, the model, which is used as an educational material, simulation, research data, archive data, etc. do.

These models are largely divided into static models and dynamic models, and are based on realistic presentation in common. In particular, in the case of a dynamic model, the dynamic system has a dynamic system that allows motion motion that is almost like a real object. For example, the model steam locomotive is basically capable of driving motion, audible direction such as driving sound and horn sound, and a visual direction of generating smoke through a stack.

It is noted that the recent technology of the smoke generator is quite close to the real steam locomotive by installing a smoke generator at the bottom of the stack, and burning the fluid by the heat of the heater in the inside so that the burned smoke is discharged to the outside of the stack. .

However, since the smoke generator continuously discharges smoke, there is a lack of realism and sense of reality because there is a visual difference from the smoke that is regularly and sterilized in synchronism with the rotation of the axle seen in a real steam locomotive.

Therefore, an intermittent smoke generating device has been proposed that ensures a distinction between when smoke comes and goes. One of them is an electromagnet which is moved forward and backward in synchronization with the rotation of the wheels by air intake formed in the upper side of the blowing fan of the smoke generating furnace as proposed in Korean Patent Registration No. 10-352917 (chimney smoke generator of a toy model locomotive). By opening and closing the air inlet repeatedly, the smoke is discharged by the suction fan and the blowing action of the blower fan. On the contrary, when the air inlet is closed, the smoke is lost and the smoke is not discharged. This allowed for intermittent emissions of smoke.

However, the related art requires an electromagnet to be installed, which entails a cost increase due to the addition of parts and difficulty in securing an electromagnet installation space. Also, when the air inlet is closed, the amount of smoke is reduced but the blowing fan is reduced. Since the smoke is continuously rotating, a small amount of smoke in the smoke generating furnace may be discharged to the outside, so the complete control of the smoke is difficult.

The other domestic patent publication No. 2001-86751 (chimney smoke generating device of toy model train) and domestic utility model registration No. 20-216552 use a piston or a piston and a solenoid, the piston in synchronization with the reciprocating motion of the piston rod When this rises, the smoke generated in the smoke generating furnace is forcedly discharged by the upward movement of the piston, and when the piston descends, the smoke is not discharged by the suction force of the piston.

However, in the prior art, since the smoke generating path, the cylinder and the piston are located in a straight line, the upward movement of the piston acts as a pressure for pushing the vitreous fiber material, so it is questioned whether the smoke discharge action is actually possible.

Another Korean Utility Model Registration No. 20-218829 is a control means capable of sudden braking and rapid starting of a fan motor, and the amount of smoke is varied according to the speed of the model train, and the discharge time of the smoke depends on the speed of the model train. And although there is an advantage to control the emissions accurately, the complete control of the smoke has a disadvantage. That is, since the smoke control is controlled only by the braking of the fan motor when the smoke is not discharged, the smoke emission amount can be reduced, but the natural emission of the smoke cannot be prevented, resulting in the smoke tail.

Accordingly, the present invention is to provide an intermittent smoke generating device of a model steam locomotive capable of regular and stealing smoke discharge without a smoke tail,

In order to achieve a more efficient discharge of smoke, a smoke discharge control valve is provided at a portion where the smoke is discharged to open only when the blower fan is operated, and the blower fan is rotated at the end of each operation cycle to stop the smoke. By implementing the exhaust completely, it is possible to produce a real steam locomotive.

The intermittent smoke generating device of the model steam locomotive of the present invention,

The heater is configured to periodically generate heat in proportion to the rotational speed of a model steam locomotive wheel and periodically burns combustible fluid embedded in a combustion furnace, and is controlled to be periodically rotated in proportion to the rotational speed of the wheel so that the combustion smoke An intermittent smoke generator of a model steam locomotive having a blower fan and a fan motor that periodically blows air; It is achieved by including a smoke discharge control valve is installed in the stack located on the upper side of the combustion furnace and opened only when the blower fan is operated.

In addition, a heater that is periodically controlled to generate heat in proportion to the number of revolutions of the model steam locomotive wheel to periodically burn the combustible fluid embedded in the combustion furnace, and is controlled to be periodically rotated in proportion to the number of revolutions of the wheel and the combustion An intermittent smoke generating device of a model steam locomotive having a blowing fan and a fan motor for periodically blowing smoke; The fan motor is achieved by including being controlled to rotate counterclockwise at the end of each operating cycle.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The model steam locomotive of the present invention provides two embodiments to produce the same intermittent smoke generating effect as the real thing.

First, the intermittent smoke generating device of the model steam locomotive of the first embodiment is controlled to periodically generate heat in proportion to the rotational speed of the wheels 2 of the model steam locomotive 1, as shown in FIGS. A heater 10 periodically burning the combustible fluid f embedded therein, and a blowing fan 30 periodically controlled to be periodically rotated in proportion to the rotation speed of the wheel 2 to periodically blow the combustion smoke. And from the intermittent smoke generating device of the model steam locomotive having a fan motor 31,

It is configured to include a smoke discharge control valve 40 is installed in the stack 21 located on the upper side of the combustion furnace 20 is opened only when the blowing fan 30 is activated. At this time, the smoke discharge control valve 40 is opened by the wind pressure according to the start of the blower fan 30, for example, to be automatically closed when the wind pressure is not applied, the ball valve is applied, in addition to the same function This one-way valve (check valves) is applicable.

Reference numeral 50 is a detection switch (or detection sensor) for detecting the number of revolutions of the wheel, 60 is a pulse generator for generating a pulse signal proportional to the number of revolutions of the wheel (2).

The intermittent smoke generator of the model steam locomotive of the first embodiment detects that the number of revolutions of the wheel 2 is large and small by the detection switch 50 when the steam locomotive 1 is driven, and then the pulse generator 60 detects that the number of revolutions of the wheel 2 is high. By monopulsing, the operating speed of the heater 10 and the blower fan 30 is controlled in proportion to the number of revolutions of the wheel.

That is, when the heater 10 is operated, combustion smoke is generated by heating and combusting the combustible fluid, and combustion smoke generated by the blower fan 30 operating at the same time as the heater is carried out through the stack 21. It is blown out. On the other hand, when the heater 10 and the blower fan 30 are not in operation, since the heater and the blower fan are in a stopped state, not only combustion smoke is generated but also no blowing power is provided so that combustion smoke is not discharged.

Therefore, as the heater 10 and the blower fan 30 are periodically operated and not operated in proportion to the rotational speed of the wheel 2, the intermittent discharge of the combustion smoke is possible.

At this time, the smoke discharge control valve 40 installed in the stack 21 is a means for more effective intermittent discharge of the smoke, is opened by the wind generated when the blowing fan 30 is operated, the blowing fan If 30 is not in operation, it is naturally closed by its own weight as no wind is provided. Therefore, the blower fan 30 and the heater 10, which are already intermittently controlled, implement the discharge of smoke primarily, and are controlled by the smoke discharge control valve 40 to double the intermittent effect. .

On the other hand, the intermittent smoke generating device of the model locomotive of the second embodiment,

The configuration is the same as that of the first embodiment described above except that there is no smoke discharge control valve 40. However, in controlling the fan motor 31, by generating a reverse rotation drive pulse from the pulse generator 60 to cause the fan motor to rotate in reverse at the end of each operation cycle in which the fan motor is rotated forward, the blowing air according to the forward rotation After the action is completed, the moment is reversed and the smoke is sucked up to make it possible to control the smoke.

4 is a pulse graph of the fan motor and the heater according to the rotational speed of the wheel, a) is a pulse wave generated from the wheel (2) as the rotational speed (v) of the wheel (2) is proportional to the pulse wave The creation cycle is faster. At this time, when the wheel 2 rotates once, the interrupter may be set to be one or two times.

b) and d) show a fan drive pulse and a heater drive pulse having the same starting point as the pulse generated by the wheel 2. From this, it can be seen that whenever a periodic pulse wave occurs in the wheel, the fan motor 31 and the heater 10 are driven at the same time in proportion to it.

c) is a fan reverse rotation driving pulse, which corresponds to the second embodiment described above, and generates a reverse rotation pulse at the end of each cycle of the fan driving pulse, thereby periodically driving the smoke immediately after blowing the smoke. This becomes possible.

As described above, the present invention,

By operating the fan motor and heater periodically in synchronism with the rotation speed of the wheels, the primary smoke control effect can be obtained, and the smoke discharge control valve can be installed to open only when the blower fan is in the place where the smoke is discharged. By rotating the motor backwards at the end of each operation cycle, it is possible to effectively control the smoke by controlling the smoke emissions again.
