A vaccine storage box is arranged in the box body in a suspension mode, ice cubes are arranged in the box body, the vaccine storage box is buried in the ice cubes, two ventilation pipes are guided out of the vaccine storage box, the air inlet pipe penetrates through the wall of the box body and is connected with a fan air outlet formed outside the box body, the air outlet pipe penetrates through the wall of the box body and is communicated with the outside, the temperature sensor is arranged in the vaccine storage box, the temperature control circuit is arranged on the box body, the temperature sensor is connected with the temperature control circuit, and the control output end of the temperature control circuit is connected with the fan. Ice is used for cooling the vaccine storage box, when the temperature in the vaccine storage box is lower than a set value, the temperature control circuit controls the fan to work, outside hot air is exchanged into the vaccine storage box, and the temperature in the vaccine storage box is kept in a needed range. The ice refrigeration micro-power vaccine deepfreeze has the advantages of being less in power consumption and reliable in work.
Description
Technical field
The utility model relates to refrigerating equipment, particularly the improvement to Portable vaccine refrigerating box.
Background technology
Vaccine is very high to the temperature requirement of preserving, if rabies vacciness, hepatitis B vaccine are 2-8 ℃ of scope ,-20 ℃～8 ℃ of influenza vaccines, measles vaccines etc., if surpass this temperature, vaccine has just lost effect, does not have prophylactic effect, harm people's health.Having injected inefficacy vaccine also likely allows people miss effective inoculation time and cause death.
Vaccine transportation, storage have special refrigerating equipment, and the inoculation of going out also has special-purpose portable refrigerating box.
Current portable refrigerating box is divided into electric refrigeration-type and ice refrigeration-type.
Electricity refrigeration-type refrigerating box needs long-term power supply, is only suitable in using onboard.
In fact ice refrigeration-type refrigerating box is exactly an incubator, and special-purpose ice raft is placed in the inside, with ice, absorbs heat to the vaccine refrigeration of lower the temperature, due to not electricity consumption, is applicable to going out inoculating use.
But ice refrigeration-type refrigerating box can not accurately be controlled temperature, because the temperature of ice raft is below 0 ℃, thereby can only preserve the vaccine of some applicable deepfreezes, as influenza, measles vaccine etc.
And rabies vacciness, hepatitis B vaccine etc. need to if temperature is too low, will make the compositions such as dispersant in vaccine freeze separation at the vaccine of 2-8 ℃ of scope storage, cause vaccine to freeze to lose efficacy, so be not suitable for ice refrigeration-type refrigerating box storage.
Utility model content
The utility model object is to provide a kind of portable refrigerating box that utilizes ice refrigeration, can accurately control temperature, is beneficial to the vaccine that storage is high to temperature requirement, and the inoculation of conveniently going out is used.
Scheme of the present utility model is: a kind of ice micro-power consumption vaccine refrigerating box that freezes, comprise casing, fan, temperature sensor and temperature-adjusting circuit, it is characterized in that: in casing, be provided with the built on stilts vaccine depository dish of surrounding, after placing ice cube in casing, vaccine depository dish is embedded in ice cube, two ventilation ducts of pass-out on vaccine depository dish, wherein blast pipe is through box body wall, be connected with the air outlet that is located at the fan outside casing, discharge pipe is in communication with the outside through box body wall, in vaccine depository dish, be provided with temperature sensor, casing is provided with temperature-adjusting circuit, temperature sensor is connected with temperature-adjusting circuit, the control output end of temperature-adjusting circuit is connected with fan.
Blast pipe and discharge pipe are separately positioned on two walls of opposition of vaccine depository dish, and air intake pipe orifice is positioned at the bottom of box wall, and air outlet tube mouth is positioned at top.
The ratio of the cross-sectional area of blast pipe, discharge pipe and vaccine depository dish cross-sectional area is 1: 100---1: between 50.
The volume of vaccine depository dish and the ratio of tank-volumes are not more than 1: 2.
Vaccine depository dish adopts can.
The utility model has the advantages that: because refrigerating box for vaccine is embedded in ice cube, utilize ice to carry out absorbing and cooling temperature to it, refrigeration reliability is high.When temperature is lower than setting value, control circuit is controlled fan work, makes extraneous hot-air exchange enter refrigerating box for vaccine, and its temperature is raise, and reaches after setting value, and fan quits work, and makes like this temperature in refrigerating box for vaccine accurately control within the required range.Owing to only having fan and control circuit electricity consumption, have advantages of that power consumption is little, only need powered battery to use the long period, the utlity model has the advantage of reliable operation.
Accompanying drawing explanation
The utility model is described in further detail according to drawings and embodiments below.
Accompanying drawing is the utility model structural representation.
Mark in figure: 1 casing, 2 refrigerating box for vaccines, 3 control boxes, 4 fans, 5 blast pipes, 6 temperature sensors, 7 vaccines, 8 ice cubes, 9 discharge pipes.
The specific embodiment
The structure of embodiment is referring to accompanying drawing, and it comprises casing 1, fan 4, temperature sensor 6 and includes temperature-adjusting circuit and the control box of battery 3.
In casing 1, be provided with vaccine depository dish 2, vaccine depository dish 2 surroundings are built on stilts, and this space is used for placing ice cube 8, places the rear vaccine depository dish 2 of ice cube 8 and be embedded in ice cube 8 in casing 1, and 8 pairs of refrigerating box for vaccines of ice cube 2 carry out cooling, realize refrigeration object.
Two ventilation ducts of pass-out on vaccine depository dish 2, wherein blast pipe 5, through box body wall, is connected with the air outlet that is located at the fan 4 outside casing, and discharge pipe 9 is in communication with the outside through box body wall.
Fan 4 adopts centrifugal fan.
In vaccine depository dish 2, be provided with temperature sensor 6, casing 1 is provided with control box 3, inside has temperature-adjusting circuit, and temperature sensor 6 is connected with temperature-adjusting circuit, and the control output end of temperature-adjusting circuit is connected with fan 4.
The ratio of the cross-sectional area of blast pipe 5, discharge pipe 9 and vaccine depository dish 2 cross-sectional areas is 1: 100---1: between 50, caliber too conference causes free convection, causes the refrigeration of cannot lowering the temperature; The too little air-supply of caliber is not smooth, is unfavorable for heat exchange.
In order to deposit enough ice cubes, to use for a long time, the ratio of the volume of vaccine depository dish 2 and casing 1 volume is not more than 1: 2.
Good in order to conduct heat, vaccine depository dish 2 adopts cans, be beneficial to and ice cube between heat exchange.
During use, when the interior temperature of refrigerating box for vaccine 2 is lower than setting value, control circuit is controlled fan 4 work, make extraneous hot-air enter refrigerating box for vaccine 2 by blast pipe 5, by discharge pipe 9, cold air is discharged again, realize cold and hot exchange, the interior temperature of refrigerating box for vaccine 2 is raise.Reach after setting value, fan 4 quits work.Make like this temperature in refrigerating box for vaccine 2 accurately control within the required range.
Control circuit is circuit common, and its structure and principle no longer describe in detail.
Owing to only having fan and control circuit electricity consumption, have advantages of that power consumption is little, only need powered battery to use the long period, the utlity model has the advantage of reliable operation.
