When the drive assembly 66 is operated to rotate the tray 19, the notches 56, 57 of the first and first optical sensors 52, 53 are rotated through the circular paths %, 94. The first optical sensor 52 detects the presence of the stationary recess 56 and sends a number 20 to the control unit 73. Similarly, the second optical sensor 53 will detect the position notch 57 and will send a signal to the control unit 73. As will be discussed in detail later, the control unit 73 typically stops the drive assembly 66 when the first optical sensor 53 detects one of the position notches 57, and activates the associated fragrance element at that location. The device group 43 includes a first optical sensor 52 and a first ring formed with a stationary recess 22 1274592

In a display mode, a bias signal is preferably input to the microcontroller U2. Pins 2, 3, 5, and 6 from controller U2 are used as outputs, and are selectively adjusted to a low level to enable the corresponding LEDs. In the selection mode, the bias signal is preferably used as the output signal from the microcontroller U2, and the state of the switch swi-SW4 is read by the corresponding pins 2, 3, 5 and 6 of the microcontroller U2. A schematic diagram of the first optical sensor 52 and the second optical sensor 53 is shown in Fig. 33. The first optical sensor 52 preferably includes a 3 kohm resistor R13, and a light emitting diode LED 6 electrically coupled in series between the 12 volt power supply and the ground potential; and a photodetector LED 8 and a 27 kΩ resistor. R15 string 24 1274592 is electrically coupled between the 5 volt power supply and ground potential. The node between the resistor R15 and the photodetector LED 8 is preferably connected to the stationary signal of the micro-controller still pin 7 as shown in FIG. When the light beam between the LED 6 and the photodetector LED 8 is interrupted, the photodetector 5 is preferably disconnected, and the microcontroller senses the high level of the still signal (5 volts). Conversely, when the light beam between the LED 6 and the photodetector LED 8 is not interrupted, the optical debt detector is preferably a short circuit between the resistor R15 and the ground potential, and the microcontroller senses the low level of the stationary signal (about volts ). Similarly, the second optical sensor 53 preferably includes a 3 kohm resistor 10 R12, and the LED diode 5 is electrically coupled between the 12 volt power supply and the ground potential; and the photodetector LEDs 7 and 27 The kilo ohm resistor RM is electrically coupled in series between the 5 volt supply and the ground potential. The node between the resistor ri4 and the photodetector LED 7 is preferably coupled to the stationary signal of the pin 7 of the microcontroller U2 shown in FIG. 15 § When the beam between LED5 and photodetector LED7 is interrupted, the photodetector is preferably disconnected, and the microcontroller senses the high level of the still signal (5 volts). Conversely, when the beam between the 5 and the optical device is not interrupted, the optical device is preferably a short circuit between the resistor IIRM and the ground potential, and the microcontroller senses the low level of the stationary signal (about volts). . Referring now to Figure 30, the blower circuit 6b preferably includes - C945 electro-crystal Q2 and a blower connector JK2 coupled to the collector of the transistor Q2. The remaining terminals of the blower connection HJK2 are preferably connected to the post power supply. The blower connector JK2 allows the blower motor 35Β (not shown) to be easily coupled to it. 0 25 1274592 Diode 1N4148 The combination of D2 and 1 kohm resistor R2 is preferably connected in series to the pin from the processor U2. 1 heater + blower signal and the base of the transistor Q2. The 47uF/16v electrolytic capacitor E3 is preferably coupled between the node N1 (between the diode D2 and the resistor R2) and the ground potential. The collector of the crystal 5 body Q2 is preferably also connected to the ground. When the heater + blower signal from the processor U2 is high, the transistor Q2 is preferably driven to an on state, which is primarily grounded to one terminal of the blower connector JK2, and allows current to flow through the blower assembly 7 〇 motor 35B . Conversely, when the heater + blower signal from the processor U2 is low and the remaining 10 charge in the capacitor E3 is insufficient to maintain the transistor Q2 in the on state, the transistor Q2 is preferably driven to the off state, A terminal of the blower connector JK2 is substantially isolated, and a current is stopped flowing through the motor 35B. The blower assembly 70 is preferably controlled during the pulse mode by applying a positive pulse to the heater + blower signal. The positive pulse is sufficient to charge capacitor E3, maintain 15 transistor Q2 in an on state, and maintain motor 35B on. However, the positive pulse is preferably insufficient to excite the NMOSFET U3, which turns the heating element 45 away, and is described later in detail. Referring again to FIG. 30, the heater circuit 62 preferably includes a heater connector JK3 coupled to the heating element 45. (Not shown in Figure 3). The heater is connected to one of the terminals of the JK3 connector to the 12 volt power supply, and the other terminal is preferably coupled to the anode of the reinforced n-channel field effect transistor nmOSFET U3, which is commercially available. The second device group was purchased and the component number SDM4532 was obtained from Angus Technical Workshop b, 7th Floor, Capital Trade Center, 62 Zhenyi Road, Guangdong, Hong Kong, China. The source of NMOSFET U3 is better grounded than 26 1274592. Combination of 1 kohm resistor R4 and 1N4148 diode D3 ###& The junction is connected between the heater from the processor and the gate of the NMOSFET U3. The capacitor 〇 is preferably coupled between the node 5 N19 (which separates the resistor R4 and the diode D3) from the ground potential. (7) The kiloohm resistor R19 is preferably coupled between the gate of the NM〇SFET U3 and the ground potential. When the heater + blower signal from processor U2 is high, NMOSFET U3 is preferably driven to an on state, which primarily grounds one terminal of heater connector JK3 and allows current to flow through the heating element. Conversely, when the heater + blower signal from the processor is still low, the NMOSFET U3 is preferably driven to the off state, which is substantially separated from the heater connection | § JK3 one terminal, stopping the current flow Via heating element 45. The heating element 45 is preferably tied to the leveling mode by applying a DC level to the heater + fan # number control. The DC level is sufficient to maintain transistor Q2 in an on state, 15 and to maintain blower assembly 70 open, turning NMOSFET U3 into an on state to maintain heating τ° 45 in the on state. Thus, when the DC level is applied to the leveling die, both the blower assembly 70 and the heating element 45 are open. Referring again to the _th, the motor circuit 64 preferably includes a motor connector m coupled to the motor 35A (not shown). The motor connector 2 is connected to the 12 volt power supply, and the other connector of the motor connector is preferably connected to the collector of the 2SD965 transistor Q1. The collector of the transistor Q1 is preferably coupled to the motor signal from the pin 14 of the processor U2 via the i kilo ohm resistor; and the emitter of the transistor is preferably grounded. The collector of transistor Q1 is preferably coupled to the source of 27 1274592 enhanced mode p-channel field effect transistor PMOSFET U3 and to the drain of PM0SFETU3 via a singular (10) pole body 〇1. The motor circuit 64 preferably includes a C945 transistor Q3, the collector of which is preferably coupled in series with a 10 kohm resistor R16 and a 1 kohm resistor R3, and 5 is coupled to the source of the PM〇SFET U3. The node N3 separating the resistors R16 and R3 is preferably coupled to the gate of the PMOS transistor U3, and the emitter of the transistor (3) is preferably grounded. The base of transistor Q3 is preferably coupled to ground via a 10 kohm resistor R18, preferably coupled to the collector of A733 transistor 10 Q4 via a 10 kohm resistor Rn. The base of transistor Q4 is preferably coupled to the motor signal from pin 14 of processor U2 via a kiloohm resistor R9, which is preferably coupled to a 5 volt supply. When the motor signal from processor U2 is high, transistor 卩丨 is preferably driven to conduct, substantially grounding first end 116 of motor connector JK1, 15 and allowing current to flow through motor 35A. Further, when the motor signal is high, the electric crystal Q4 is turned off, and the transistor q3 is turned off. This interrupts the current path through the resistors R16, R3 and transistor Q3 from the 12 volt supply, so the maximum amount of current will flow through the motor 35A. In addition, when transistor Q3 is off, PMOSFET U3 is turned off, separating first and second terminals 116, 118 of motor 35A across PMOSFET U3. Conversely, when the motor signal from processor U2 is low, transistor Q1 is preferably turned off, which substantially separates first terminal 116 of motor connector JK1 from ground potential, and stops current flow through motor 35A. In addition, when the motor signal is low, the transistor Q4 is preferably driven to be turned on, so that the transistor q3 is driven to be the transistor 28 1274592. This provides a current path from the 12 volt supply through resistors R16, R3 and transistor q3, which further directs current from motor 35A. In addition, when the transistor Q3 is turned on, pm〇SFEtu3 becomes conductive, causing the first terminal and the second terminal 丨", 118 of the motor 35A to be short-circuited via the 5 PMOSFET U3 to ensure the first motor terminal and the second motor terminal 116, 118. There is no voltage drop between them. Thus, according to the present invention, the motor circuit 64 provides at least two types of machine rotation, which interrupts the rotation of the motor 35A as quickly as possible in response to the motor signal from the processor U2. Referring again to the % map, The table below shows the voltage and resistance approximation values for each position shown in Figure 30, and the motor 10 35A is running or stopped: the voltage value of the motor 35A at the operating position and the stop position and the position value of the resistance value shown in Figure 30. Voltage 5 volts 0 volts MOSFET impedance south Z short circuit N3 voltage 12 volts 1 · 〇 7 volts N6 voltage 0 volts 12 volts N7 voltage 0 volts 0.7 volts N8 voltage 〇 volts 12 volts N9 voltage 0.7 volts volts volts 3rd figure shows heat The resistor R11, preferably the series-connected capacitor C2' is interposed between the SNR signal of the microcontroller U2 pin 8 and the ground potential. The thermistor im is measurable due to temperature changes. The fixed resistance change 'so the microcontroller 15 U2 preferably uses the SNR signal as an input signal to monitor the temperature near the heater element. 29 1274592 Resistor R10 is preferably a series coupled capacitor C2, which is connected to the microcontroller U2. The REF signal of the pin 9 is between the ground potential and the microcontroller U2 preferably uses the REF signal as a reference signal for comparison with the SNR signal to counteract the influence of fluctuations in the surrounding temperature. The microcontroller U2 is preferably charged via the CRG signal. The C2, CRG signal is coupled to the microcontroller U2 pin 10 to the capacitor C2. The micro-control U2 then monitors the pulse width of the SNR signal, which is related to the resistance of the thermistor R11 to determine the temperature in the vicinity of the heating element 45. The invention will now be further described with reference to the accompanying drawings which illustrate the operation of the device group 43. The user typically first inserts a 12 volt DC power pack into the output 10, supplies power to the device set 43, and couples via the socket 36 shown in FIG. The device group is connected to a 12 volt power supply. Next, the user inserts the cassette 42 into the cassette accommodating cavity 47 and closes the top cover 7. The control unit 73 will receive power, and the card 42 is pressed. The electric switch 78 (the switch SW1 of Fig. 32) is located in the cassette accommodating cavity 47. The latch 31 is engaged at the lip portion 82 of the bottom portion 8 of the top cover 7, initially maintaining the device group 43 in the closed position of the seal 15, while the cassette 42 The inner turntable and the shallow tray 19 are in the rest position. Next, the user presses the right control panel U before the button 13 to activate the drive assembly 66 and the blower assembly 70. Once the shallow tray 19 is rotated from the rest position, the top cover 7 Will be locked in the closed position until the shallow pan 19 returns to the rest position. Preferably, the advance-skip printed circuit board 34iLED4 will rotate when the turntable is rotated to position the first fragrance element in the heater assembly 68, alerting the user that the turntable is already rotating. After the first fragrance element is in the heating assembly, the heating element 45 is activated, and preferably the LED 4 enters from the flashing state to a stable lighting state. The heating element 45 is typically rated to a built-in setting, typically including low, medium and high strength. The strength is better displayed on the left control panel 1〇, and the left control panel can be pressed by 30 1274592 to select 2. (4) Unit 73 can be assembled to the last intensity level selected by the memory user to actuate the card E42. Preferably, the control element Cui 73 monitors the temperature of the heating element 45 and applies a pulsed current to the heating element 维持 to maintain the desired level of intensity. The temperature can usually be monitored using thermistor R11 as shown in Figure 31. 5 The scent element of the cassette 42 is usually activated for a period of time which is selected to be long enough for the user to understand and perceive the aroma, but does not exceed the time the user desensitizes the fragrance, and desensitizes the fragrance occasionally. It is called "fragrance fatigue" or "accustomed to it". Reference is made to U.S. Patent Application: us 0068010 A. The operating time is about 15 minutes to 6 minutes and preferably about 10 minutes. The actuation time is usually also related to the activation of the fragrance body time and the fragrance element time after diffusion activation. When activated by heating the scented body, it was found that it is generally not necessary to activate the scented body to diffuse throughout the actuation phase. It is thus preferred to activate the fragrance element to undergo a shorter period of time than the actuation time selected for diffusion-activated fragrance element. The shorter time is from about 5 minutes to 1 minute 15 minutes and preferably about 8 minutes. For example, when the actuation time of the fragrance element after diffusion activation is selected to be about 30 minutes, the appropriate time for the activation of the element is about 22 minutes. This is advantageous because it allows the scent element to cool for about 8 minutes before allowing the inner turntable of the card (10) to be rotated. After the activation time of the fragrance element (usually about 3 minutes) after diffusion activation exceeds 20 hours, the control unit 73 preferably rotates the turntable to position the next fragrance element above the heating assembly 68. When the 'turntable rotates' again, the LEIM__ of the printed circuit board 34 is skipped. This New Fortune is restored to the last scented body. After the last scent element has been actuated, the control unit will continue to operate the blower assembly 70 while monitoring the temperature. After the device group has a temperature drop of 31 1274592 to 70 °C, the turntable will eventually be rotated to the rest position. When the user decides to stop the advancement of the card maker before the entire fragrance element is actuated, the user can press the advance 13 again. The electronic control unit turns off the heating assembly 68' preferably causes the LED 4 to begin to flash again. The control unit 73 continues to operate the blower assembly 70 while monitoring the temperature. Once the temperature drops below 7 ,, the device set 43 turns the turntable to the rest position and closes the blower assembly 70 and LED 4 °. When the user decides to skip a scent element, the user can press the jump Ha 14 control unit 73 normally The heating assembly 68 is turned off, preferably 10 LED4 is again flashed. The control unit 73 also continuously operates the blower assembly % while rotating the turntable to the secondary position. Once the next scent element reaches the upper position of the heating assembly, the normal program will be restored. However, if the skip button 14 is pressed when the device group state pushes the last scent element, the control unit 73 will be in the same manner as the user presses the advance button 13 as before. The device group 15 is operated 43, and the device group 43 is stopped. If the device group 43 is powered down during operation, the control unit is configured to return the turntable to the rest position after the power is restored. In addition, device group 43 will enter the standby mode after the device is powered. Referring now to Figs. 36 to S6, there is shown a second specific example of the device group 43 in which the volatilization of the material according to the present invention is carried out in accordance with the material (4). Comparing the figures to the first embodiment shown in the figure, the second embodiment typically includes modifications of the drive assembly 66, the addition _, the formation 68, and the positioning assembly 72. The operation of device group 43 and the associated details of control unit 73 remain unchanged. The relevant modifications are detailed later. Referring now to Figure 41, the spring damper 40 32 1274592 shown in Figures 8 and 15 is replaced by a combination of a gear 40A and a plurality of teeth 4 〇 B. The top housing 2 includes a gear 40A that is assembled to cooperate with a plurality of teeth formed at the bottom §. As illustrated, the bottom 8 series is configured to cooperate with at least one torsion spring % to open the rear grip cover 7 in a substantially upright position. When the cover 75 is opened, the combination of the gear 4A and the tooth 40B assists in controlling the operation of the torsion spring %. Gear 40A is preferably packaged in a grease selected to slow the action of cover 7. Referring now to Figures 51 through 54, similar to the first embodiment of the present invention shown in Figures 19 through 22, the drive assembly 66 and the positioning assembly 72 comprise a shallow disc 19, where the latch recess 84A has a tapered outer shape. . The latch recess 84A is again positioned at the rest position of the corresponding pocket 42 of the platter "week 10 edge 88. The tapered profile helps to determine that the latch 31 returns to the closed position shown in Figure 42 during operation of the device set. This may occur when the top cover 7 is opened and then the latch 31 is closed incompletely and not returned to the closed position. The tapered outer profile can smoothly return the key 86 of the latch 31 to the closed position when the shallow disk 19 is rotated, as shown in Figures 55 and 56. Referring now to Figures 4, 41, 42, 46 and 55, the cassette receiving cavity 47 formed in the top housing 2 includes a pair of circular openings 74A and rectangular openings 76A which are respectively arranged Cooperating with a pair of ejection members 41 and an electric switch. The ejection member 41A includes a spring 41B to assist in removing the card E mounted to the card receiving cavity 47. The electric switch 78A is coupled to the cavity The side branch 78B supports 'as shown in Fig. 42, and the current supplied to the main printed circuit board 32 will be cut off unless the cassette is mounted on the card, and the inner I 87. Now refer to Fig. 45 and 47 to 50, the drive assembly 66 includes a motor 35A and an evening gear 19, 2, 22, %, %, 27, 28, % are arranged in a hub 21 that rotates around the rotating shaft 110. The plurality of gears regroup 33 1274592 synthesizes a total of 953:1 gear reduction ratio to transmit 5 pieces of broken torque at a speed of about 3 seconds per revolution. The wheel is 21, as described above for the first aspect of the invention. ~ The motor 35A is coupled to the amp 2, and the worm is coupled to the worm wheel a. The shank is coupled to the first-wheel 23, which engages the second field. ^ - The pinion 23 is more than the face - the dance piece to the second record 26, and preferably (four) A shot W wheel 4 series light joint ugly pregnancy is formed into a part. The second small tooth 10 15 20 joint third The rib, the third gear 27 is engaged with the first gear 28. The four large gears 28 are coupled to the fourth pinion 30 by the fourth gear sleeve 29. The fourth large gear 28, the fourth gear sleeve 29 and the fourth The pinion gear is formed into a part. The first, the wire 3G is joined with the wheel (10) mounted thereon. The second specific wealth of the invention is compared with the first concrete example of the 15th to the _th. A small tooth is I. The height of the first large gear 24, the second small gear 26, the second wheel 27 and the fourth large gear 28 of the wheel 23 is higher than that of the shallow disk. The first one of the present invention In the example, the 'the pinion gear 23 is lightly coupled to the bottom of the worm wheel 22. As shown in the figure m, the first pinion 23 is coupled to the top of the worm wheel 22, and in the second specific example, the gear height is substantially increased. 40 and 43, the heating assembly (10) is similar to the first embodiment of the invention, including the heating element being closed to the heater cover 2 to be heated between the plungers 17. In the second specific example, the heating is performed. The cover is coupled to the heater plunger 17 by means of a fastener such as a screw. & Although a specific example of the present invention has been described with reference to the drawings, it should be understood that this is not limited to such specific examples. Those skilled in the art may make various other changes and modifications without departing from the scope or essence of the present invention.
