The uranium music player (53) can be one of the following, Mp3, ip〇D, CD Walkman, radio, mobile phone, PDA, etc., so that the user can change the music at any time. The alarm device (10') of the second embodiment of the present invention is implemented by engaging the buckle 4 (61) of the casing (6) with the buckle groove (71) of the gas furnace (7) to form a detachable alarm device. In this way, the setting position of the alarm device (1〇,) of the present invention can be adjusted to facilitate the proximity detection of the combustion state of the fire source of the burner, and the housing (6) can be rotated to adjust the gas sensor at any time (33). The distance between the burner and the fire source of the burner, and the reduction of the cooking device collision warning device 〇〇, during the cooking process. In addition, as shown in FIG. 6, the usage of the alarm device (1〇, 1〇,) of the present invention is as follows: 201137287 Step A 'Confirm and adjust the setting of the alarm device (1〇, 1〇,) and the fire. Position; step B, turning on the alarm device (1〇, 1〇,), causing the alarm device (1〇, 10') to perform a warm-up procedure; step C, 4 waiting for the first in the warm-up circuit (31) When the warning light (yeah) is lit, the warm-up procedure is completed; in step D, the adjustable resistance (10) in the sensing circuit (32) is continuously adjusted, and the state-of-warning 7F lamp (D4) is turned off, And the buzzer ((2) operation situation; and ν Ε Ε 、 、, cook condition to confirm whether to cancel the buzzer (μ) operation; if yes, then turn off the buzzer (22) when needed (such as leaving the gas furnace When the operation is resumed; if not, the alarm device (1〇, 1〇,) is normally operated. In the above step, the first switch (23) of the control circuit (2) is pressed to turn on the power to make the gas The sensor (10) and the music playing unit (5) are electrically operated, and the steps Β and the steps described above can be reversed. In the above step C, when warming up, due to the first comparator (10) in the warm-up circuit (8), the input terminal (ie, connected to the step-down resistor (R42); see Figure 3-1), The initial voltage is about 5 volts (v), which is higher than the initial voltage at the other input. Therefore, it needs to be programmed to 2 minutes to allow the voltage at the other input to flow through the current limiting resistor (R38) to the capacitor. (4) Charging, so that the voltage gradually rises and exceeds, the first comparison output is turned on and the first warning light (10) is illuminated, so that the first crystal (four) obtains a normal _ bias and is connected in series. The second transistor _ is functioning normally. The former Chunshi capacitor ((2) will be charged, and will be discharged through the diode (10) 15 201137287. Therefore, after the mother turns the power back on, it takes 1 to 2 minutes, and the warm-up time can be boosted to the appropriate operation. , H to achieve the circuit protection effect. ' In the above step D, when the gas sensor (33) is warmed up, the voltage drop value generated by the load resistor (10) 2) in the sensor circuit (32) will Depending on the type of gas sensor (33)' control is between 范围3 to 2 volts (V). Therefore, when the first warning light (D6) in the warm-up circuit (31) is on (refer to Figure 3~1), the adjustable resistance (R31) needs to be connected to remove the static DC of the load resistor (R32). The voltage, until the second warning light (D4) is illuminated, and then the fine adjustment adjustable resistor (10) 1) is returned, so that the second warning light (10) is not lit, so that the voltage of the second comparator (U2A) can be made The critical point at which the second warning light (D4) is illuminated is activated, and the turtle pressure between the second comparator (U2A) and the adjustable resistor (R31) is slightly higher than that of the second comparator (U2A). The voltage at the other input pin is about 〇 2 volts (V), so that the sensing sensitivity of the gas sensor (33) is kept at an optimum state. In the above step E, since there are two general cooking conditions, in which case the user wants to cook while listening to music, but does not need the buzzer (22) to operate, the second switch (24) is pressed. The alarm sound is released, and then the buzzer (22) is resumed when needed (such as when leaving the gas oven), but at this time the user's environment has been contaminated by soot, so it is necessary to see whether the buzzer (22) makes a sound. To confirm that the sensing sensitivity of the gas sensor (33) is kept in an optimal state, if the buzzer (22) makes a sound, the above step D procedure is performed; otherwise, the alarm device (10, 10,) is normal. Operation. The second situation is that when cooking, there is no need for the user to wait at the gas stove (7) at any time, so that the alarm will be activated, so that the user can pay attention to the fire through the music. When the gas cannot be effectively burned, the pin voltage of the second comparator (10) and the gas: rise f) will be affected by the gas ❹m(10) and the playback unit (5) will be cut and cut by T'. At this time, the control IC (21) will Stop the sound (4) heart' and let the bee D, lii (22) sound an alarm sounding carbon oxide to produce the body. This miscellaneous person can react early, and inhale too much discomfort. The embodiment of the feature details the construction of the coffee, but the new one is straightforward. The self-finance touches the progressive element, and the love is according to the law; but the above is only the preferred embodiment of the present invention, but The culvert belongs to the invention: =: Γ定触围, therefore, what is the meaning of the present invention, cross-linking, as long as it is within the range of equal range. 17 201137287 [Simple description of the drawing] Fig. 1.
