Technical field
The present invention relates to a kind of armarium, for preventing the respiratory infectious disease of air-borne transmission, it is that a kind of improved expansible plug-in type killing in the air pathogen mixes fan housing.
Background technology
At present, the mixed wind exhaust passage of sterilizing concentrated by a kind of medicament, its equipment body is the casing with air inlet and air vent, box body wall is provided with for the spout to spraying agent in casing, casing section perpendicular to air flow is disposed with the filter layer that fabric is made, and the surrounding being close to filter layer is disposed with the filter layer that fixed fabric makes and injects the aperture of liquid to it and its operation principle of lid of aperture is：Utilize box body wall setting for spraying sterilized pharmaceutics in the spout of spraying agent in casing to casing, sterilized pharmaceutics is mixed in casing with air, reaches sterilization effect.Casing section perpendicular to air flow is disposed with the filter layer that fabric is made, and this filter layer can reach sterilization effect with immersion liquid sterilized pharmaceutics when air-flow passes through.Can prevent patient exhalation gas in line outdoor infection others' the drawbacks of.
But, if medicament more than one to be sprayed, the said equipment just seems unable to do what one wishes.If the negative pressure of mixed fan housing is too high, patient may feel that mask suction is too strong, inspiratory dyspnea.It is exactly also the sealing problem patching junction.The present invention is exactly to propose and solve this 3 problems.
Content of the invention
Now above-mentioned in order to overcome：If medicament more than one to be sprayed, the said equipment just seems unable to do what one wishes；If the negative pressure of mixed fan housing is too high, patient may feel that mask suction is too strong, inspiratory dyspnea；Patch the poorly sealed deficiency of junction, the present invention provides a kind of improved expansible plug-in type to mix fan housing.
The technical solution adopted for the present invention to solve the technical problems is：Single mixed fan housing includes air vent interface, air inlet interface, cydariform cylindrical cavity, pressurized seal pipe, pressurized seal pipe joint, sterilized pharmaceutics spray orifice, pressure sealing ring；Air inlet interface therein is connected with diameter greater than air vent interface diameter, air inlet interface, air vent interface, cydariform cylindrical cavity, and sterilized pharmaceutics spray orifice is located on cydariform cylindrical cavity；Including pressurized seal pipe cecum plug, pressurized seal pipe heating pipe joint, pressurized seal pipe air supply pipe, pressure sealing ring, pressure switch；One mixed fan housing air vent interface patches within the air inlet interface of another mixed fan housing, pressure sealing ring is therebetween, the pressurized seal Gutron of 2 mixed fan housings is crossed pressurized seal pipe joint and is linked to be a path, its end pressurized seal pipe cecum plug is blocked, the other end connects pressurized seal pipe air supply pipe by pressurized seal pipe heating pipe joint, pressurized seal pipe air supply pipe connects pressure switch, and pressurized seal pipe air supply pipe connects electric air pump；Pressure switch controls starting and the stopping of electric air pump, and when pressurized seal pipe supply pipe pressure is less than reset values, pressure switch contact is connected, electric air pump is controlled to start, when pressurized seal pipe supply pipe pressure is higher than setting value, pressure switch contact disconnects, and controls electric air pump to stop.
Adjust valve, butterfly valve element, negative pressure connection end, actuator, manual operator, servo amplifier including negative pressure transmitter, electronic butterfly, negative pressure transmitter measurement therein mixes the negative pressure of fan housing inner air, negative pressure connection end connects the negative pressure source including air-introduced machine entrance, electronic butterfly adjustment valve is arranged between negative pressure connection end and negative pressure transmitter measuring point, and butterfly valve element adjusts air mass flow；The signal of telecommunication of negative pressure transmitter is electrically connected to PID regulator, becomes closed-loop regulating system with manual operator, servo amplifier, electronic butterfly adjustment valve group, adjusts air mass flow by butterfly valve element butterfly valve core and maintains mixed fan housing negative pressure near setting value.
Or, mixed fan housing casing is made of plastic, or is made with metal, or is made with moistureproof paper.
Or, described taper air inlet section and exhaust section such as turning adopt screw thread tubular construction.
Including described in patch junction and fixed using screw and nut, all of screw and nut bar is all vertically machined with the latus rectum circular hole penetrating, and is easy to lock pin and passes through, and after plus lock pin, increased the fastness entirely mixing fan housing..
Its operation principle is：As grafting iron sheet chimney, series connection one by one is plugged together, to use various medicaments, more preferably, cydariform cylindrical cavity therein slow down the flow velocity of air to sterilization effect, is easy to medicament and has air subject to sterilization to mix, reaches sterilization effect.In order to strengthen sealing effectiveness, employ pressure sealing ring, one mixed fan housing air vent interface patches within the air inlet interface of another mixed fan housing, pressure sealing ring is therebetween, the pressurized seal Gutron of 2 mixed fan housings is crossed pressurized seal pipe joint and is linked to be a path, its end pressurized seal pipe cecum plug is blocked, and the other end connects pressurized seal pipe air supply pipe by pressurized seal pipe heating pipe joint, defines an airtight pressurized seal system.In order to ensure the pressure of pressure sealing ring, pressurized seal pipe air supply pipe connects pressure switch, and pressure switch controls electric air pump to start and stops it is ensured that the pressure of pressure sealing ring.Closed-loop regulating system adjusts air mass flow by butterfly valve element butterfly valve core and maintains mixed fan housing negative pressure near setting value.
The invention has the beneficial effects as follows：1. allow to spray the sterilized pharmaceutics of more than one；And by contrast, prior art, due to only having 1 sterilized pharmaceutics spray orifice, can only spray a kind of sterilized pharmaceutics.2. use closed-loop regulating system to adjust mixed fan housing negative pressure, patient respiration is comfortable on；And by contrast, the uncontrollable mixed fan housing negative pressure of prior art, the negative pressure as mixed fan housing is too high, and patient may feel that mask suction is too strong, inspiratory dyspnea.3. junction aeroseal is good, due to employ pressure sealing ring patching to connect, effectively increases junction aeroseal performance；And by contrast, prior art patches junction gap, poorly sealed.
