Description

A kind of air purifying lamp

Technical field

The utility model relates to a kind of light fixture, and more particularly, it relates to a kind of air purifying lamp.

Background technology

Negative ion air purification energy saving lamp is that a kind of by energy-efficient high-tech product together with environmental protection perfect adaptation, product had both had good illumination effect, and energy conservation characteristic possesses again and purifies air, sterilization, sterilization, deodorizing smoke eliminating function.LED anion air purification lamp is also known as clean aldehyde lamp, be produce anion complex device microminiaturization after with energy-efficient lamp perfect adaptation, while light-illuminating, a large amount of anions can be produced and intersperse among space, thus play smoke abatement and dust control and eliminate the unusual smell, disinfection is dispelled the multiple efficacies such as pollution, being widely used in the Recreational places such as hotel, hotel, office, meeting room, family and tearoom, singing-hall, Internet bar, is the excellent product improving air quality, eliminate the pernicious gas such as formaldehyde, benzene.

This product can discharge a large amount of free electron while illumination, the oxygen of free electron in air is combined and produces the negativity ion being of value to health in a large number, discharge huge energy (this response class is like the lightning with the rainy day simultaneously, to thunder effect), the whole interior space is diffused into equably and with multiple harmful substances molecule in air as viruses molecule by the fuel factor anion of light, smog molecular reaction, thus make viruses molecule change structure or power conversion, play sterilization, sterilization, eliminates the unusual smell and the effect of smoke removing.

But there is a problem in the anion air purification lamp tool existed at present, due to need first by the boost in voltage in subminiature air cleaner (Mini negative ions generator) to 8KV and more than, if need to purify a large amount of dust, bacterium, the electric energy that unit interval can dissipate is not a peanut, and when after the germ Cell binding in anion and air, make the structural change of cell interior energy trasfer, cause it dead.And making benzene floating in air, toluene, formaldehyde, cigarette, dirt, pollen etc. attract particle to gather and natural subsidence, natural subsidence certainly will need certain hour, and in this time, upper air is still purified in fact, now produces reactive loss larger.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is that providing a kind of controls subminiature air cleaner by arranging multivibrator, while realizing providing to timing dust suction one effect that purifies air most possibly, ensure that its power consumption is lower.

For achieving the above object, the utility model provides following technical scheme: a kind of air purifying lamp, comprise subminiature air cleaner, described subminiature air cleaner is electrically connected with external ac power source by booster circuit, described subminiature air cleaner is coupled with protection switch, described protection switch is controlled by blocking circuit, described blocking circuit comprises multivibrator and Executive Module, described Executive Module is coupled to the output of multivibrator, and during multivibrator output high level, described Executive Module sends executive signal Control protection switch and closes, subminiature air cleaner is obtained electric.

The utility model can be set to further: described multivibrator comprises 555 timing chips, described 555 timing chips the 8th pin and the 4th pin couple, its second pin and the 6th pin couple, the second divider resistance and the 3rd divider resistance is coupled with between second pin and the 4th pin, the node that described second divider resistance and the 3rd divider resistance couple formation is connected to the 7th pin of 555 timing chips, be coupled with the 4th electric capacity between second pin of 555 timing chips and ground end, between the 5th pin of 555 timing chips and ground end, be coupled with the 5th electric capacity.

The utility model can be set to further: described 3rd divider resistance is adjustable resistance.

The utility model can be set to further: be coupled with press button between the 4th pin of described 555 timing chips and power supply high level.

The utility model can be set to further: described Executive Module comprises an optical coupler and a relay coil, and described optical coupler is controlled by multivibrator, and when the output of described multivibrator exports high level, relay coil adhesive protection switch closes.

By adopting technique scheme, compared to existing technology, serve following beneficial effect: because subminiature air cleaner exists the process of a sedimentation, in the process of sedimentation, control subminiature air cleaner power down, thus realize the function of economize on electricity, and when after a period of time, electric work can be obtained by again controlling subminiature air cleaner, make this lamp again exhale anion, ensure that under the prerequisite of lowest power consumption, serve the effect purified air.

Detailed description of the invention

Referring to figs. 1 through Fig. 2, the utility model embodiment is described further.

A kind of air purifying lamp; comprise subminiature air cleaner 13; subminiature air cleaner is electrically connected with external ac power source by booster circuit 11; subminiature air cleaner 13 is coupled with protection switch; protection switch is controlled by blocking circuit; blocking circuit comprises multivibrator 2 and Executive Module 3; Executive Module 3 is coupled to the output of multivibrator 2; and multivibrator 2 is when exporting high level; Executive Module 3 sends executive signal Control protection switch and closes, and subminiature air cleaner 13 is obtained electric.

With reference to shown in Fig. 1, the concrete annexation of booster circuit 1111 and function as follows: be provided with an external ac power source interface, for being connected with family expenses 220V AC power, its positive input terminal is connected to a rectifying tube D1, for carrying out halfwave rectifier to external ac power source, the output of rectifying tube is coupled with the first resistance R1, the other end of the first resistance R1 is by a filter capacitor C1 ground connection, for carrying out voltage stabilizing process to half wave rectified signal, described filter capacitor C1 is parallel with resonant component, described resonant component comprises the second resistance R2 be arranged in series successively, 3rd resistance R3 and the second electric capacity C2, the node that second electric capacity C2 and the 3rd resistance R3 couples also is coupled with the 4th resistance R4, 4th resistance R4 is connected to the control pole of controllable silicon SCR, controllable silicon is for controlling static discharge during over-voltage and over-current.As shown in Figure 1, also comprise a transformer 1212B, transformer 1212B turn ratio can be set to 24:900 circle; in order to realize boost function; protection switch and a rectifying tube D2, its rectification withstand voltage is 15KV, and a dividing potential drop protective resistance is connected on the loop at vice-side winding place jointly.
