Abstract
The utility model relates to a mini-size ultraviolet disinfecting instrument, comprising a casing and a lamp holder which is arranged on the top of the casing, and the inner part of the casing is provided with a direct-current source, a switch, and a circuit block. The positive pole and the negative pole of the direct-current source are connected with the causing light circuit through a switch K; the light circuit is the output circuit of the push-pull oscillation formed by a transistor D1, a transistor D2, and an oscillation transformer T, and the output circuit of the push-pull oscillation is added to the two poles of the ultraviolet lamp by the high voltage pulse of the secondary output of the oscillation transformer T. The lamp holder can rotate corresponding to the casing, and the mini-size ultraviolet disinfecting instrument is convenient to conduct the surface sterilization to the articles in all kinds of occasions.
Description
The utility model belongs to disinfector, particularly a kind of micro type ultra-violet disinfecting instrument.
No matter ultraviolet ray disinfector of the prior art is a power supply with direct current or with the interchange, volume is all bigger, and ultraviolet radiation intensity is low, and direction of illumination can not change, and is of limited application.It is made up of single tube DC converter and AC and DC electric power system as " the efficient portable AC/DC ultraviolet sterilizer " of CN2105283U report.During work, it is luminous that the monolateral pulse voltage that relies on monolateral transistor converter vibration to produce removes to promote the ultra-violet lamp starter.There are two deficiencies in this structure, and the one, DC transfer circuit efficient is low, can only export monolateral pulse voltage, and then influences the luminous intensity of uviol lamp; Secondly, be that the charging circuit complexity is unreasonable, in fact can not realize AC/DC, and be a kind of poor efficiency DC circuit.
It is low that the purpose of this utility model provides a kind of power consumption, ultraviolet intensity height, the micro type ultra-violet disinfecting instrument that bactericidal effect is good.
The utility model comprises shell, in the enclosure DC power supply, switch and circuit block are installed, and is installed in the shell top, is equipped with the lamp holder of ultra-violet lamp in it.The both positive and negative polarity of DC power supply by K switch with cause optical circuit and link to each other, cause optical circuit and form push-pull oscillator circuit by transistor D1, D2 and oscillation transformer T, the two poles of the earth of the secondary and ultra-violet lamp of oscillation transformer T link to each other.
Because the bilateral circuit that the utility model adopts two transistor D1, D2 to form forms push-pull oscillator output, produces bilateral pulse, improves the efficient of circuit, the ultra-violet lamp luminous intensity is improved, and energy consumption is low.
Describe embodiments of the invention in detail below in conjunction with accompanying drawing.
The utility model is made up of shell 4 and lamp holder 3, in shell 4 DC power supply is installed, switch and circuit block; Be equipped with ultra-violet lamp 2 in the lamp holder 3.Link to each other by anchor 7 between lamp holder 3 and the shell 4.Lamp holder 3 can rotate around the strand nail, is convenient in various occasions the difformity article surface be sterilized.
Circuit of the present utility model as shown in Figure 3, Figure 4.The both positive and negative polarity of DC power supply by K switch with cause optical circuit and link to each other, cause optical circuit and form the push-pull oscillator output circuit by transistor D1, D2 and oscillation transformer T, secondary the two poles of the earth with ultra-violet lamp Rf of oscillation transformer T link to each other.Variable resistor R2 adjusts the oscillator working point.
The utility model adopts rechargeable battery as DC power supply.To battery charge, on circuit block, also be equipped with the charging circuit that bleeder resistance R1 and bridge rectifier ZL form by energy storage capacitor C for easily.Rectifier output end links to each other with the DC power supply same polarity.
Ultra-violet lamp in the lamp holder is perpendicular with dish circular lamp face 2 by fired 2, two electrodes of dish circular lamp face 5 that form of quartz glass tube.By the positioner in the lamp holder ultra-violet lamp is fixed therein, with lead 6 time extremely linking to each other the oscillation transformer T in the two poles of the earth 5 and the circuit.
Description of drawings:
Fig. 1 is the front view of present embodiment, and Fig. 2 is its vertical view, and Fig. 3 is the circuit block diagram of present embodiment, and Fig. 4 is the circuit theory diagrams of present embodiment.
Claims (3)
