The PTC (Positive Temperature Coefficient) device used in the present invention is a kind of thermistor. The thermistor is a 2 ~ 2 oxide so that oxides such as cobalt, copper, manganese, iron, nickel, titanium and the like have an appropriate resistivity and a temperature coefficient. Three kinds of mixed and sintered semiconductors are roughly classified into NTC and PTC, and the semiconductor device is an electronic circuit device having a conductivity sensitive to changes in ambient temperature. Originally a trade name of Western, Inc., USA, it has recently been generalized as a pronoun of semiconductor devices for temperature detection.

Unlike ordinary metals, NTC (Negative Temperature Coefficient) thermistors have the characteristic of negative resistance temperature coefficient which decreases the resistance value as the temperature increases. ) It is classified into heat dissipation type and delay type, and there are various kinds of appearances from enlightenment to coin size.

It is used as a sensor for temperature control because it has a small heat capacity and a sudden resistance change occurs even at a slight temperature change.It is used for measuring temperature thermometer, thermometer, hygrometer, barometer, wind speed meter, microwave power meter, etc. The fields of use are wide, including automatic gain adjustment of communication lines.

Also, positive temperature coefficient (PTC) thermistor is a thermistor whose resistance value increases as the temperature increases, which has a positive resistance temperature coefficient of 0.1% of tin and cerium in the barium titanate-based semiconductor. It is made by mixing about. The sudden change in resistance at a certain temperature is called a critical temperature resistor (CTR).

2 to 5, the low-power handy heat transfer sealer according to the present invention is used in a state separated into the heat transfer sealer body 1 and the charger body (5), when the use is completed in a combined manner to charge again Used.

The heat-sealing sealer body 1 is further divided into a base 31 and a pressing unit 32. The base 31 is a sealer for controlling the PTC heater 16 and the PTC heater 16 to generate heat. A unit driving circuit, a switch 2 for operating the sealer unit driving circuit 10, an operation lamp 4 for displaying the operating state of the sealer unit driving circuit 10 to the outside, and an external power source By charging the power and the switch 4 is turned on, the rechargeable battery 14 for supplying the charged power to the PTC heater 16 is built-in, the pressing unit 32 is supported by the base 31 in a rotational manner When the user exerts a force, the PTC heater 16 is provided to press the PTC heater 16 provided on the base 31.

In addition, the charger body 5 integrally integrates a power supply circuit (not shown), a transformer 21, and a multiplication voltage generator 22 to charge the rechargeable battery 14 embedded in the heat sealer body 1. An anion generating circuit 20 is included, and an outer predetermined portion is provided with an anion discharging unit 6 which discharges an anion generated by the anion generator 23 of the anion generating circuit 20 to the outside.

The base 31 and the pressing portion 32 constituting the heat-sealing sealer body 1 are formed of a resin having heat resistance and impact resistance, and the upper end portion is bent to the left side as shown in FIG. In order to smoothly perform the sealing operation from the starting point of the sealing member during the operation, the predetermined portion of the side of the base 31 is provided with the operation lamp 4 consisting of two-color LED, red (R) depending on the use state Alternatively, the green color G is turned on.

In addition, the predetermined portion of the side of the base 31 is provided with a switch 2 for operating the heat-sealing sealer according to the present invention, the user of the base 31 and the predetermined portion outside the pressing portion 32 of the heat-sealing sealer. An anti-slip plate 3 is formed to easily hold the main body 1, and power supplied from the power supply unit of the charger main body 5 may be supplied to the rechargeable battery 14 on both sides of the lower part of the base 31. The charging terminal 7 is provided.

On the other hand, as another embodiment of the present invention, it is possible to propose a low-power handy heat transfer sealer composed of only the heat transfer sealer body (1) without having a separate charger body (5), in this case in the charger body (5) The DC jack 11 to be used is provided in place of the charging terminal 7 to receive external power.

Hereinafter, the driving circuit of the sealer unit used in the present invention will be described in detail by the circuit diagram shown in FIG.

The sealer unit driving circuit 10 normally operates in the unit driving circuit 10 even when the polarity of the DC jack 11 for supplying external power to the circuit and the external power supplied through the DC jack 11 is reversed. The bridge diode 12 for supplying power, the zener diode Dz for supplying a stable voltage to the rechargeable battery by restricting the supplied voltage not to exceed a predetermined value, and the zener diode Dz and the bridge diode 12 The transistor Q1, which controls the PTC sensor 13 by a power source, is installed in the vicinity of the rechargeable battery 14 to serve as a temperature sensor, and when the rechargeable battery 14 is heated, the rechargeable battery 14 is increased by an increased resistance. The PTC sensor 13 for limiting the power supplied to the switch, the switch 2 for operating the PTC heater 16 of the sealer unit driving circuit 10, and the bridge diode when the switch 2 is turned on ( 12) through It consists of PTC heater 16 that generates heat by the supplied power, and 2 color LEDs of red LED 17 and green LED 18, and changes depending on the connection state of power and the operating state of PTC heater 16. When the operating lamp 4 and the PTC heater 16 are installed in close proximity to each other to serve as a temperature sensor, and the resistance value is initially large, only the red LED 17 is turned on and the PTC heater 16 is heated. It consists of the NTC sensor 15 which lights only the green LED 18 by the resistance value reduced.

The current supplied through the DC jack 11 is supplied to the circuit through the bridge diode 12, the supplied current to drive the transistor T1 through a zener diode (Dz) to perform a constant voltage action, the transistor T1 The PTC sensor 13 charges the rechargeable battery 14 embedded in the heat-sealing sealer base 31.

The reason for using the bridge diode 12 in the present invention is that when the AC power supplied from an external power supply (not shown) is converted into DC by an adapter, the polarity of the DC power is incorrectly connected to the circuit. In order to prevent the direct current from being supplied, a circuit using the zener diode Dz is used to charge the rechargeable battery 14 at a stable voltage.

In addition, the PTC sensor 13 is a kind of static thermistor whose resistance increases when the temperature is high. In the initial state, the PTC sensor 13 does not generate heat and heat generated in the discharged battery 14 is discharged. Since the PTC sensor 13 has a small resistance value, the current supplied through the transistor T1 quickly charges the rechargeable battery 14,

On the other hand, if the current is continuously supplied to the PTC sensor 13 and the rechargeable battery 14, the PTC sensor 13 and the rechargeable battery 14 generates heat, and thus the resistance value of the PTC sensor 13 is increased to fully charge the battery. Since the current supplied to the PTC sensor 13 and the rechargeable battery 14 is limited, overcharging of the rechargeable battery 14 is prevented.

On the other hand, when the switch 2 provided in the heat-sealing sealer body 1 is turned off, the power supplied through the bridge diode 12 passes through the resistors R2 and R3 along the circuit branched immediately before the diode D5, and then the operating lamp ( It is supplied to the red LED 17 of 4), the red LED 17 is dimly lit by the resistance value to confirm that the power is connected to the heat seal body (1).

When the user turns on the switch 2 provided in the heat-sealing sealer body 1, the electric current discharged from the rechargeable battery 14 is supplied to the PTC heater 16 via the diode D6 and at the same time, the NTC sensor ( 15, and therefore the red LED 17 of the operation lamp 4 connected in parallel to the NTC sensor 15 is brightly lit.

Since the NTC sensor 15 has the characteristic of negative resistance temperature coefficient that the resistance decreases as the temperature increases, the initial resistance value is large, thereby limiting the current. When the heat is generated from the adjacent PTC heater 16, the resistance gradually increases. As the value decreases, the amount of current flowing increases.

Therefore, in the initial stage when the switch 2 is turned on, the red LED 17 connected in parallel with the NTC sensor 15 is turned on by the current supplied through the diode D7, but in series with the NTC sensor 15. The green LED 18 of the connected operation lamp 4 does not light up, and when the resistance value of the NTC sensor 15 decreases due to the heat generation of the PTC heater 16, the NTC sensor 15 is short-circuited. Since there is almost no value, the green LED 18 is turned on and the red LED 17 is turned off.

On the other hand, the charger main body 5 is provided with an anion generator circuit 20 having an anion generator 23, the anion generated by the negative ion generator 23 is the negative ion discharge portion 6 of the charger main body 5 Is emitted through the outside.

The negative ion generating circuit 20 is a secondary coil of the transformer 21 when the current supply interruption is repeated to the primary coil of the transformer 21 by the power supplied from a power supply (not shown) as shown in FIG. AC voltage is induced at.

In addition, the AC voltage induced in the secondary coil of the transformer 21 is applied to the voltage of one terminal of the output side to the multiplication voltage generator 22, the voltage of the other terminal on the output side of the negative electrode of the negative ion generator 23 ( And the voltage applied to the multiplication voltage generator 22 is rectified by a multiplication circuit in which capacitors C10-C17 and diodes D6-D13 are connected in a ladder form. After amplified by a high voltage DC voltage, a zero-potential is applied to the negative ion generator 23.

Therefore, a gas discharge is generated by applying a very high voltage between the zero potential of the anion generator 23 and the cathode (-), and when the gas discharge occurs, an anion is generated by the discharge phenomenon. The generated negative ions are discharged to the outside through the negative ion releasing part 6 provided in the charger main body 5.

The low-power handy heat transfer sealer according to the present invention uses a PTC heater 16 with low power consumption instead of a conventional nichrome wire as a heat generating member constituting the heater of the sealer unit, and controls the operation state of the PTC heater 16. The PTC sensor 16 which controls the rechargeable battery 14 inside the heat-sealing sealer main body 1 with the NTC sensor 15 is equipped with the heat-sealing sealer body 1 to the charger main body 5 after a user uses a heat-sealing sealer. When inserted, the rechargeable battery 14 built in the heat sealer body 1 is recharged and can be used repeatedly without replacing the battery, and the top of the heat sealer body 1 is made in an inclined state to the left side from the beginning of the sealing member. In order to effectively seal and increase the efficiency of the sealing operation, the negative ion discharge unit 6 provided on one side of the charger main body 5 to discharge the negative ions to the outside to purify the air in the room It works.
