Description

Timer

The utility model relates to a kind of health care clock apparatus, belongs to daily necessities field.

The clock that uses in people's daily life has only effects such as demonstration time, decoration, and still, cleaning with fresh air in the holding chamber has become the demand that people live.By retrieval as can be known, also there is not the clock apparatus of harmful bacteria in a kind of energy fresh air, the elimination air to come out at present.

The purpose of this utility model is a kind of novel clock apparatus of design, and it has can produce an amount of negative ion at the appropriate time, plays fresh air, eliminates effect such as harmful bacteria and health care in the air.

In order to realize above-mentioned task, the technical solution of the utility model is: the housing that circuit board, anion generator will be housed is fixed on the clock, circuit board in the housing connects with external power supply by lead, the output of circuit board connects with anion generator by lead, circuit board is provided with power circuit, automatic control circuit and negative ion generating circuit, makes clock apparatus.During use the utility model is fixed on wall or the furniture convenient the use.

The utlity model has that simple in structure, applicability is strong, characteristics such as power consumptive province, easy to use, reasonable price.

Be further described selecting for use crystal clock to make the utility model below in conjunction with drawings and Examples:

Fig. 1 is a structure diagram of the present utility model;

Fig. 2 is the A-A cut-open view of structure diagram of the present utility model;

Fig. 3 is the circuit theory diagrams of the utility model first embodiment;

Fig. 4 is the circuit theory diagrams of the utility model second embodiment.

1 is lead among the figure; 2 is housing; 3 is crystal clock; 4 is screw; 5 is anion generator; 6 is small fan; 7 is circuit board.

Embodiment 1: as Fig. 1, Fig. 2, shown in Figure 3, with the screw (4) that is distributed on the housing (2) housing (2) is fixed on the crystal clock (3), circuit board (7) is fixed on the housing (2), anion generator (5) is fixed on the housing (2); The circuit board (7) that is fixed on the housing (2) connects with external power supply by lead (1), and its output connects with anion generator (5) by lead (1).Circuit board (7) is provided with power circuit, automatic control circuit, negative ion generating circuit.

Establishing by transformer B1 on the circuit board (7) is the step-down of 220V power supply the 12V power supply; the rectification circuit of diode D1, D2, each composition of D3, D4 plays rectified action; is the rectification of 12V AC power direct supply; filter capacitor C1; the 9V DC power supply circuit that photoresistance GR, integrated regulator IC1 form, fuse RD shields to circuit.When indoor light is brighter, photoresistance GR resistance less (about tens Europe), power circuit is normally exported; When light was dark, photoresistance GR resistance is big (about tens kilo-ohms), and power circuit is not exported.The smoke sensitive circuit that automatic control circuit is made up of electrochemical capacitor C2, gas sensor HQ-II, resistance R 1, R2, diode D5, triode T1, resistance R 3 and by diode D6, capacitor C 3, resistance R 4, diode D7, triode T2, resistance R 5, diode D8, capacitor C 4, resistance R 6, triode T3, contact-making switch AN1, two compositions of time circuit that relay J 1 and LED are formed.The closed and disconnected of relay J 1 is being controlled the power supply and the outage of negative ion generating circuit respectively.Negative ion generating circuit is boosted to the 220V AC power about 650V by transformer B2, boost through the voltage doubling rectifing circuit of forming by capacitor C 5, C6, C7, C8 and diode D9, D10, D11, D12, direct supply about output 1300V, 7 metering functions of resistance R.Just can make clock apparatus with said method.

During use this clock apparatus is fixed on wall or the furniture, when indoor smoke is dense, when air is dirty, can produces an amount of negative ion, kill harmful bacterium, fresh air.

Embodiment two: as Fig. 1, Fig. 2, shown in Figure 4, with the screw (4) that is distributed on the housing (2) small fan (6) is fixed on the housing (2), be positioned between circuit board (7) and the anion generator (5), the blowing wind direction of small fan (6) faces anion generator (5), and the low pressure output of circuit board (7) connects with small fan (6) by lead (1).On circuit board (7), establish power circuit, automatic control circuit and negative ion generating circuit.Power circuit is the step-down of 220V AC power the 12V power supply by transformer B1, through diode D1, D2, D3, the rectification circuit rectification of each composition of D4 is a direct supply, filter capacitor C1 strobes, timing circuit does not have the output of giving the correct time evening ten by the program control clock IC1(that gets ready up to 5 o'clock mornings of next day), two joint dry cells, contact-making switch AN1, each one of AN2, capacitor C 2, C3, C4, each one of C5, resistance R 1, triode T1, resistance R 2, the clock circuit that diode D5 forms and by capacitor C 6, triode T2, resistance R 3, R4 integrated circuit (IC) 2, triode T3, relay J 1, circuit was formed when 90 minutes of forming of resistance R 5 were built, integrated regulator IC3 plays pressure stabilization function, forms power circuit by said method; The automatic control circuit of present embodiment, negative ion generating circuit principle and embodiment 1 are identical.Power supply, the outage of small fan (6), anion generator (5) are controlled in closure, the disconnection of the relay J 2 in the automatic control circuit respectively simultaneously, and 13 pairs of small fans of resistance R (6) motor plays metering function.Make the utility model with said method, have dense in indoor smoke, when air is dirty, produce an amount of negative ion, fresh air and kill harmful bacteria in the air, and when night, 10 o'clock Ban were to m seq six, automatic control circuit, negative ion generating circuit no power are saved electric energy, and the reliability of element is provided.
