Description

Multifunctional anti-fungus cupboard for endoscope

The utility model is mainly used in endoscope mildew-resistant in the medical department, dries up, deposits; Also can be used for the mildew-resistant of camera, microscope, camera lens and other optical instrument and precious article and deposit.

Both at home and abroad to the endoscope mildew-resistant, mainly adopt the silica gel moisture absorption at present, infrared ray, electric furnace toast or dehumidify with dehumidifier, but poor effect.Silica gel moisture absorption again when relative humidity 45%; Non-uniform temperature when infrared ray, electric furnace baking, also wayward; Indoor relative humidity can not be dropped to below 45% at mould Pluvial dehumidifier; Thereby endoscope still mildews.

The purpose of this utility model has solved the mildew-resistant of endoscope and optical instrument camera lens; Realized that endoscope dries up automation; Also can deposit endoscope and optical instrument.So both kept the original definition of endoscope, and improved the accuracy of diagnosis and treatment again, thereby be with a wide range of applications.

Technology of the present utility model solves the sheet case:

The multi-functional mildew-resistant cabinet of endoscope during mainly by automatic temperature control circuit, holding circuit, control circuit form.

The utility model is used the bridge balance principle and temperature is controlled BG ₀Two base stages link to each other BG with the electric bridge brachium pontis ₁Meet BG ₀Single-ended output, BG ₂Base stage meets BG ₁Output, C ₁With BG ₂Form trigger impulse and produce circuit, the trigger impulse of generation is through T ₂BCR is touched out in coupling output; BG ₃Base stage links to each other J with the RT contact ₁With BG ₃Emitter stage links to each other, when the RT conducting, and BG ₃Work, J ₁Work, J ₁During work, J _1-1Disconnect J _1-2Connect and report to the police; J _1-1Connect J with RH _1-2Connect BG with Y ₄Be connected on J _2-2Normally closed contact and C ₂Between, BG ₅Be connected on BG ₄Output, J ₂Be connected on BG ₅Colelctor electrode, J ₃Be connected on both ends of power; M ₁, M meets 220V, and is subjected to J _3-1Normal opened contact control, solenoid meets C ₃Two ends, C ₄, D ₁, D ₂, C ₃Form two voltage doubling rectifying circuit, solenoid work is subjected to J _3-2Often open, normally closed contact control.

Advantage of the present utility model:

Mildew-resistant is superior, and drying up saves time saves trouble, and dries up applicable to the endoscope of various models; A tractor serves several purposes; Capacity is big, can put 7 endoscopes, three religion mirrors and other optical lens; Winter, scope was placed in the cabinet suitable with body temperature, can keep flexibility, avoided optical fiber to fracture, and reduced advantages such as patient's misery and discomfort.

Below in conjunction with accompanying drawing the utility model is further described:

One, automatic temperature control circuit

Using the bridge balance principle controls temperature.When temperature reaches predetermined value, bridge balance, heater quits work, when the thermostat temperature skew, as not enough thermostat temperature, thermistor R _tResistance increases, and makes the electric bridge disequilibrium, differential pair tube BG ₀Produce potential difference between two base stages (3DG6), cause difference to put the output current potential and descend, thereby change BG ₁Duty (3CG5) makes BG ₁Tube voltage drop descends, and shortens C ₁In the charging interval of (0.1 μ F) electric capacity, trigger impulse produces in advance, and the BCR angle of flow increases, and RH heater strip terminal voltage raises, and makes in-cabinet temperature near thermostat temperature.When reaching thermostat temperature, R+(thermistor) resistance descends, thereby makes bridge balance, and the time that causes trigger impulse to produce is delayed the BCR(controllable silicon) angle of flow diminishes, and load RH terminal voltage reduces, and makes in-cabinet temperature reach constant temperature.BG in the circuit ₂Be BT ₃₃

Two, holding circuit

When in-cabinet temperature is put temperature above maximum prefetch, protection contact RT(mercurial thermometer) connect, thus make BG ₃(3DG12) conducting, J ₁Relay work, J _1-1Disconnect (cutting off RH end power supply), simultaneously J _1-2Closure, the y(loudspeaker) send chimes of doom, can guarantee circuit safety like this.

Circuit when three, controlling

(1) electric capacity charging process:

Dry up button K when pressing ₁: capacitor C ₂(220 μ) when being charged to certain value, BG ₄(3DJ6E) conducting makes BG ₅(3DG130) conducting, J ₂Work and self-locking; J ₃Relay is connected A: J in the push-button reset circuit _3-2Often open, normally closed contact is connected respectively, disconnect.J _3-2The normal opened contact closure, C ₄(470 μ), D ₁(N4001), D ₂(N4001), C ₃(2200 μ) forms two voltage-multiplying circuits, makes C ₃Two ends reach the 54V crest voltage, prepare for the electromagnetism pin resets.B:J _3-1Closure, M ₁(blower fan), M(air pump) work.

(2) capacitor discharge process:

Work as capacitor C ₂When discharging into certain value: BG ₄Do not work BG ₅End J ₂Relay discharges, J _2-2Often open, normally closed contact recovers ortho states; J ₃Relay outage A:J _3-2Often open, normally closed contact disconnects respectively, connect C ₃To the solenoid discharge, the electromagnetism pin is resetted; B:J _3-1Disconnect M ₁, M outage.
