Description

  The present invention relates to a further improvement on a smokeless smoking device. Specifically, by connecting two circuits (input circuit and output circuit) to one input / output terminal of the embedded 8-bit microcomputer, more input / output can be controlled by the microcomputer The

  The smokeless smoking devices are the ones described in detail in Patent Documents 1 to 5 and, by inserting a commercially available filter-attached cigarette or heat stick into these jigs, smoke smoking or It is a smoking device that can smoke without smoking. Heat Stick is a cigarette with a filter that is used by inserting it into a smoking jig called Aikos that Philip Morris launched in Japan in 2014. In addition, BAT launched a smoking jig called Glow in Sendai City in 2016. And filter cigarettes used for glow are said to be Neostek. These are said to be heated cigarettes and are sold very well in recent years. These filter cigarettes use chemically treated tobacco leaves that produce smoke when heated, and are shaped like cigarettes with filters, but filters that are used with normal fire The attached cigarette is finished in a shape different in thickness and length. Filtered cigarettes for ICOS are about 7.2φ long and 45 mm long, and filter cigarettes for glow are about 5.2φ long and 83 mm long. The filter section of these filter-backed cigarettes is made in Skaska for transport to the smoker's mouth without absorbing the nicotine and smoke generated by tobacco leaf heating.

  Among these smokeless smoking devices, in particular, using a heat stick, in Patent Document 5, as a second embodiment, the smokeless smoking device disclosed in FIG. 2 can switch between smoked smoking and smokeless smoking, and can smoke In places where smoke is smoked, smoke with smoke just like smoking with ordinary fire, and in places where smoking is fooled, switch to smokeless smoking and enjoy smoke-free smoking Well, very popular.

In addition, this smokeless smoking device can set the heating temperature of the heater that heats the inserted tobacco leaf to three levels at the time of smoke smoking and smokeless smoking respectively, and the smoker sets the desired temperature You can now enjoy smoking and this feature is also well received by smokers.

However, in order to incorporate the control circuit into the smokeless smoking device, it is necessary to make the circuit small, and the 8-bit microcomputer used is a part number PIC12F675 or PIC12F683, as shown in FIG. Since there are only 8 pins, there are only 6 input / output pins other than Vdd and GND.

The six input / output pins are assigned as shown below in the smokeless smoking device. (See Figure 1)
・ 7 pin = GP0 / AN0 = measurement of input voltage ・ 6 pin = GP1 / AN1 = ON / OFF of red LED of D1
・ 5 pin = GP2 / AN2 = control voltage supply to Heater ・ 4 pin = GP3 = SW2 input ・ 3 pin = GP4 / AN3 = D1 green LED ON / OFF
・ 2pin = GP5 = Voltage supply control to BUZZER

Because of this assignment, the smokeless smoking device settings state, ie smokeless smoking / smoked smoking setting, furthermore, heater heating temperature setting (three stages), and 2x3 setting smokers The only way to confirm that setting is by the color and blinking state of the two-color diode D1 and the time and number of times BUZZER sounds. In the smokeless smoking device, smokeless smoking is green, smoked smoking is orange and two-color diode color, and the heating temperature setting is SW2 during about 5 seconds of blinking of the LED immediately after the power is turned on. The number of times the button is pressed is set, and the result is notified by the number of vibrations of BUZZER. Using the method.

However, there is a problem that this method is complicated and can not be used by the blind. There are many requests from users of the smokeless smoking device whether it can be reduced to a special purpose machine with less functions or can be changed into an easy-to-understand setting method.

FIG. 3 is an axial cross-sectional view of the smokeless smoking device 100 disclosed in FIG. 2 in Patent Document 5. FIG. 1 shows a drive circuit used in the smokeless smoking device 100. In the present invention, a slide SW having 1 circuit and 3 contacts shown in FIG. 2 and a setting condition input circuit consisting of 4 resistors are added to 3Pin and 6Pin of the drive circuit, and a smoke switch is used using slide SW21. We devised to be able to set the heating temperature of the heater by using the setting of smokeless smoking and the slide SW 22. The In1 terminal of FIG. 2 is connected to 3Pin of FIG. 1, and the In2 terminal is connected to 6Pin of FIG.

Control circuit diagram used for the smokeless smoking device disclosed in Patent Document 5 Setting condition input circuit made of slide SW and resistor according to the present invention The figure which added slide SW21 and 22 used for the setting condition input circuit of Example 1 of this application to back lid 200 of the axial direction sectional view of the smokeless smoking tool disclosed as patent document 5 as FIG. The appearance of the back cover to which the setting condition input circuit according to the first embodiment of the present invention is attached Pin function diagram of the 8-bit microcomputer used in the drive circuit in Figure 1

  FIG. 1 is a drive circuit diagram used in a conventional smokeless smoking device 100 disclosed in Patent Document 5. As shown in FIG. CN1 is a connector that receives a power supply voltage (DC 3.3 to 4.2 V) powered by a lithium ion rechargeable battery. IC2 is an IC that generates a stable voltage of DC 2.8 to 3.0 V from the power supply voltage. The IC 1 is an 8-bit microcomputer, in which software for driving the heater is written. D1 is a red and green two-color diode which can display red, green and orange. R1 and R2 are the current limiting resistors.

  The heater driving software written in the 8-bit microcomputer is made to operate as follows. When the smoker turns on, the two-color diode D1 blinks in orange (indicating that it is smoked) for 3 seconds. When the button SW2 is pressed during this blinking, the light turns green (indicating a smokeless smoking state) blinking. After blinking for 3 seconds, it turns on for 5 seconds. During this lighting, the heater heating temperature is set by the number of times the button SW is pressed. The number of times of pressing is 1 to 3 times (three or more times are determined to be 3 times). The heater heating temperature is the lowest at one time, and the heater heating temperature is the highest at three times. After lighting for 5 seconds, lighting for about 25 seconds of orange or green continues. During this time, the power supply voltage (DC 3.3 to 4.2 V) is continuously applied to the heater, and the surface temperature of the heater rapidly rises to shorten the time until the start of smoking. After about 25 seconds, BUZZER vibrates to indicate that it is possible to smoke. In addition, BUZZER vibrates at power ON, at the start of smoking, 30 seconds before the end of smoking, and at the end of smoking. When the power is turned on, the vibration should be short once (smoke smoking) or twice (smokeless smoking). When smoking starts or ends, it vibrates for a long time, and the number of vibrations vibrates for a set number of times of heating. The signal 30 seconds before the end of smoking is once with a long vibration.

  As described above, the heater drive software is made and explained to the smoker in the manual, but the user's reputation is complicated. More easily. Unfavorable.

  Smokeless / smokeless setting. Three heater heating temperature settings. It is obvious that it will be very easy to use if it is possible to set 2 × 3 settings before smoking starts. However, as can be seen from the circuit diagram of FIG. 1, all six input / output pins of the 8-bit microcomputer are used, and there is no pin for reading these set values. In order to solve this problem, it is easy to use an 8-bit microcomputer with 10Pin or more input / output Pin, but actually the shape of the microcomputer becomes large and it can not be incorporated into a smokeless smoking device There is a problem that the price of the microcomputer goes up and the price of the smokeless smoking tool goes up.

  Therefore, the inventor of the present invention can set the above six conditions or more before the start of smoking while using the current 8-bit microcomputer having six input / output pins, and the setting is visible or Even if you can not see, I devised a method to touch and understand settings.

  FIG. 2 shows a setting condition constituted by the slide SW 21 having three contacts of one circuit according to the first embodiment of the present invention, four resistors, and the slide SW 22 and four resistors proposed to solve the above problems. Two input circuits are shown.

  In1 of this circuit is connected to 3Pin of IC1 and In2 is connected to 6Pin of IC1. Further, Vout is connected to 1Pin of IC1 and GND is connected to 8Pin of IC1.

  The slide switches 21 and 22 are attached to the back cover 200 of FIG. The description of each part in FIG. 3 is described in detail in Patent Document 5, so the description is omitted here, but added are the slide SW 21 and 22 attached to the back lid 200, and BUZZER 201 Only.

  As shown in FIG. 4, two slides SW21 and SW22 are attached side by side to the back cover 200, and one to three protrusions 23, 24 are also formed on the side part of the knob of the slide SW like Braille. Because there is a pit, even the blind can tell where the position of the knob of the slide SW is.

  In FIG. 2, two setting condition input circuits by the slide SW and four resistors are shown. By connecting the circuit as described above, since one diode and one setting condition input circuit are connected to 3Pin and 6Pin of IC1, it can not be used as it is. However, as can be seen from FIG. 5, 7, 6, 5, and 3Pin can be used also as an output terminal (GP) and also as an input terminal (AN). The present invention was made using this function.

  First, a green diode, its limiting resistor R2 and In1 of FIG. 2 are connected to 3Pin of IC1. The voltage of In1 when the slide SW 21 is at the contact point (3) can be calculated by the formula: Vout x R / (R 20 + R), R = [R 2 x (R 21 + R 22 + R 23)] / (R 2 + R 21 + R 22 + R 23). Similarly, it is obvious that the calculation can be made when the contacts (2) and (1) are in place. Here, in the case of Vout = 3.0V, R2 = 330Ω, R20 to R23 = 680Ω, the voltage of In1 is 0.88V in the case of being at the contact point (3). 0.49 V if at contact (2). When the contact (1) is present, it becomes 0.29V. Similarly, in the case of the slide SW22, in the case of R2 = 510 Ω and R30 to R33 = 680 Ω. Contact point (3) = 0.97V. Contact point (2) = 0.65V. The contact point (1) is 0.35 V. Therefore, for example, if 3Pin and 6Pin are input Pin and this voltage is measured immediately after the power is turned on, it becomes possible to read into the microcomputer which contact point of the slide SW 21, 22 is.

  However, since the diode connected at the time of reading can not be turned on, it is necessary to add certain restrictions to the resistors R20 to R23 and R30 to R33 constituting the setting condition input circuit. That is, when the slide SW is at the contact point (3), the voltage of In1 or In2 is equal to or less than the voltage at which the diode lights up. Specifically, when the voltage at which the diode lights up is 1.5 V, the voltage needs to be set to 1.0 V or less. If all the resistors have the same value, calculation of about 680Ω is found to be good.

  After the reading is completed, 3Pin and 6Pin change to turn on the diode, but at the same time voltage is also applied to the setting condition input circuit, so current flows, but current flowing to the heater is very high. Because it is large, it can be ignored as the power consumption of smokeless smoking devices.

  Such a setting condition input circuit can also be connected to 5Pin (a heater is connected), so that, if necessary, another setting condition input circuit can be added.

  By adding the setting condition input circuit, when the power is turned on, the voltage of each of the slide SW 21 and 22 is measured and the setting of each slide SW is (1), (2), (3) I created a software that reads which one of At this measurement, since the terminal voltage of In1 and In2 is 1.0 V or less, the diode does not light. Thus, when the setting of the slide SW1 is (1) when the power is ON, smoke-free smoking, and (3) smokeless smoking. (2) If it is smoke smoking, it can be read that it is possible to smoke for about 10 minutes It was set to loose smoking. Furthermore, if the setting of the slide SW 2 is (1), the heater heating setting = 1, if (2) the heater heating setting = 2, and if (3) the heater heating setting = 3, it is possible to read became.

  As described above, by reading the setting of the slide SW when the power is turned on, it is apparent that the smokeless smoking device can be used by using the conventionally incorporated heater driving software.

  By adding the setting condition input circuit while using the 8-bit microcomputer used in the conventional smokeless smoking tool as it is, the setting of three smoking methods and three heating temperatures is visible and touched with a finger. It became understandable, and it became very easy to use smokeless smoking device.
