Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to a liquid fuel combustion device having a storage battery or the like.

<Prior Art> A conventional liquid fuel combustion device includes a wick lifting device, an ignition device, and an odor control device, and each of these devices is operated using power from a power source. However, when using a storage battery such as a dry cell battery as a power source, two AA dry cell batteries (DC 3V) cannot normally be used for one season, so a separate storage battery power source is used for each device.

However, when a storage battery power source is provided for each of the ignition heater device, the wick lifting device, and the deodorizing device in this way, the power consumption of each device is different, and therefore the consumption timing of each storage battery is also different. There are some inconveniences such as the ignition device working even though the storage battery of the wick lifting device is exhausted, or the wick lifting device working and the ignition device working but the odor control device not working, etc., making it difficult to use the device smoothly. The disadvantage was that it was unable to perform its functions.

<Purpose> In view of the above, the present invention utilizes the same storage battery power source to utilize the difference in power consumption of each device to accurately notify the inoperable state of each device, and to create a liquid that can maintain smooth usage. The present invention aims to provide a fuel combustion device.

<Example> An example of the present invention shown in FIGS. 1 to 3 will be described below.

The connecting plate 20 has an engaging pin 13 near the outer periphery of the cam 21.
are engaged through. Then, the core lifting motor 23 is connected to the cam 2 via the motor mounting board 17.
The core lifting motor 2 is arranged in the opposite direction to the core lifting motor 2.
The motor shaft 24 of No. 3 passes through the motor mounting board 17 and is fitted into the cam 21. The cam 21
A first micro switch 25 for switching the core lifting/lowering motor 23 is installed on the base plate 17 close to above. Further, a second micro switch 26 for switching the heater delay circuit board 10 is installed above the other end of the motor mounting board 17, and a third micro switch 26 for switching the deodorizing delay circuit board 29 is installed below the other end of the motor mounting board 17. A micro switch 27 is installed.

The deodorizing device 5 is installed on the upper surface of the fuel tank 8, and the deodorizing device 5 is provided with a deodorizing motor 31, which is attached together with an exhaust pipe 32 to a deodorizing motor mounting case 33. The upper surface of the exhaust pipe 32 is provided with a plurality of exhaust holes 34.

As shown in FIG. 1, one terminal of the heater delay circuit board 10 is connected to the second microswitch 26 and connected to the anode side of the storage battery 1, and the other terminal is connected to the cathode side of the storage battery 1. . One terminal of the core lifting/lowering motor 23 is connected to a parallel connection of a power switch 35 and a first microswitch 25, and is connected to the anode side of the storage battery 1. Note that the power switch 35 has a structure that can immediately return to the OFF state by a spring or the like after inputting the power. The other terminal of the core lifting/lowering motor 23 is connected to the cathode side of the storage battery 1. One terminal of the deodorizing delay circuit board 29 is connected to the third microswitch 27 and connected to the anode side of the storage battery 1, and the other terminal is connected to the cathode side of the storage battery 1 and is connected to the output side of the deodorizing delay circuit board 29. A deodorizing motor 31 is connected to the deodorizing motor 31. That is, the core lifting/lowering motor 23, the heater 9, and the deodorizing motor 31, which are formed by connecting each switch, are connected in parallel.

Next, to explain the operation, first, when not in use,
As shown by the chain line in FIG. 2, the actuating plate 18 is at position B. In this state, the contact of the first microswitch 25 is located in the recess 22a of the cam 21 and is not turned on. When the power switch 35 is turned on from this state, the core lifting motor 23 rotates clockwise in the figure (A
direction), and the cam 21 rotates in the A direction.
After that, the power switch 35 is turned OFF, but at this point, the first micro switch 25 is turned ON by the rotation of the cam 21, so the core lifting motor 2
3 continues to rotate. And the recess 22b of the cam 21
When the switch rotates upward and reaches the contact position of the first micro switch 25, the first micro switch 25
is turned OFF and the core lifting/lowering motor 23 stops.
In this state, the connecting plate 20 is pushed down, and the actuating plate 18 is pushed up in the C direction around the centering axis 15, and the second micro switch 26 is opened at the right end of the connecting plate 20.
is turned on, the heater 9 is energized to red-hot, and the combustion wick 2 can be ignited. At this time, the heater delay circuit board 10 is energized for about 10 seconds.

When the fire is extinguished, when the power switch 35 is turned on, the wick lifting motor 23 rotates in the A direction, as in the case of ignition, and the cam 21 rotates in the A direction. Similarly to the ignition, when the power switch 35 is OFF, the rotation of the cam 21 has already turned off the first micro switch 25.
is ON, the core lifting motor 23 continues to rotate, and when the recess 22a of the cam 21 reaches the contact position of the first micro switch 25, the first micro switch is turned OFF and the core lifting motor 23 is stopped. do. At this time, the connecting plate 20 is pushed up, and the actuating plate 18 is pushed down in the direction B around the centering axis 15, and the third micro switch 2 is opened at its right end.
5 is turned on to rotate the deodorizing motor 31 and discharge the gas in the fuel tank 8 to the outside of the tank. The deodorizing delay circuit board 29 is energized for about 75 seconds.

Next, to explain the order in which the battery consumption status is notified, the current flowing to the heater 9 is 1100 mA, and the current flowing to the core lifting motor 23 is
The current flowing through the deodorizing motor 31 is 60 mA. Therefore, the heater 9 consumes the largest amount of power, followed by the core lifting motor 2.
3. It becomes the deodorizing motor 31. When the consumption of the storage battery 1 progresses, first of all, the red heat of the heater 9 becomes worse and the wick cannot be ignited, which can indicate that the consumption of the storage battery 1 has progressed. In this state, the storage battery 1 may be replaced with a new one. Furthermore, even if the ignition becomes impossible, the wick lifting device 3 and the deodorizing device 5 operate, so for example, if the heater 9 stops operating, it is possible to ignite the wick several dozen times using a match, lighter, etc. The lifting motor 23 and the deodorizing motor 31 can be operated.

In the case of the present invention, there is a problem that it cannot be maintained for one season with two AA batteries (DC 3V), but this can be solved by using batteries with a long power supply period.

As described above, as shown in FIG. 1, in this embodiment, the storage battery 1 is used as a power source for all devices, and the difference in power consumption of each device is effectively used to operate each device. It has the great advantage of being able to notify you of your disability.

It should be noted that the present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

<Effects> As is clear from the above explanation, the present invention has an ignition device for igniting a combustion wick, a wick lifting device for raising and lowering the combustion wick, and an ignition device for raising and lowering the combustion wick, each of which has successively lower power consumption. The device is equipped with an odor prevention device that reduces the odor caused by the gas, and the same storage battery is used as the power source for each device.

Therefore, according to the present invention, by using the same storage battery power source, the power consumption of each device is different, so it is possible to prevent the ignition device from operating even though the wick lifting device is not operating due to consumption of the storage battery. It is possible to ensure safety.

Moreover, if the wick lifting device is activated and the wick is lowered when extinguishing a fire, the deodorizing device will be activated afterwards, reducing the odor generated when extinguishing the fire, thereby ensuring comfort.

Furthermore, since the power consumption of each device is different, the power consumption decreases in the order of ignition device, wick lifting device, and deodorizing device, so you can accurately know that the other devices are working properly whenever you ignite the ignition device. It has excellent effects.
