DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small-sized incense burner of the incense-burning type, and in particular, uses a direct current such as a battery as a heating source, and maintains an optimal heating temperature for a long time with minimum power by a heat storage structure and an electronic circuit. The present invention relates to an electronic censer capable of continuously adjusting a heating temperature.

[0002]

2. Description of the Related Art Conventionally, incense burners that burn incense and prize it include those that ignite and burn the incense itself formed in the incense burner,
There is a type that raises charcoal, puts ash on the top, controls the temperature with its thickness, and burns incense, or a type that burns incense by heating through a heating element. Some of the heat sources use a charcoal fire, a coal briquette, an alcohol, a candle, an electric heater using a general-purpose AC power supply (AC commercial power supply), or the like.

[0003]

In the above-mentioned incense burner, the method of heating a perfume with a heating element using a charcoal or the like has problems in terms of sustainability of heating and temperature control. Electric heaters that use a power supply, etc., always have a long power cord for supplying power to the heater, which impairs the beauty of the set incense burner itself, especially when burning natural high-grade incense wood. In an entertaining environment, the person may not be accustomed to an atmosphere that produces wabi, loneliness, silence, religious feelings, and the like. In addition, in the case of a standing behavior, the power cord may be hooked and the censer may fall. In addition, the portable power supply cannot be used in the outdoors where a commercial power supply is not nearby, or cannot be used in an area where the commercial power supply voltage is different. However, if you want to use it for a long time in a specific place, especially if you want to use it for commercial power by attaching a cord,
Care must also be taken.

Are fixed, and the variable resistor VR1 is varied. The switching voltage output from the switching IC A1 switches the transistor Q2 via the transistor Q1, and turns on (energizes) and turns off (stops) the heater 25 (RH). As for the above time, assuming that time is t, ton = 3.8 m / s and toff = 40 μ / s
1.4 m / s, the ratio D can be changed from D = 98.7% to 73%.
The temperature of the combustion dish due to the heat generated by the heat is 190 ° C. to 250 ° C.
Can be changed continuously.

In general, incense woods containing a large amount of extract are used at a relatively low temperature, and those containing a large amount of wood are often used at a high temperature.
° C, agarwood 210 ° ~ 230 ° C, sandalwood 220 ° ~
250 ° C is said to be a suitable temperature. However, there are many types of incense wood, and some types are blended. And
It is said that the ultimate incense that burns incense and wins prizes is the range of individual sensibility, and the setting of the optimal combustion temperature for each type of incense depends on the individuality of each individual. In this electronic incense burner, power consumption can be minimized by adopting an electronic circuit, and by setting the temperature setting knob to the temperature display scale, it is possible to freely select the optimal combustion temperature that suits each individual's sensitivity. Also, reproduction is easy.
