The power supply of the incubator 10 can be used by directly receiving power through the automotive power source 194 or the commercial AC power source 196, and can also be used by charging the power supply battery 192.

7A and 7B are views for explaining an example of a detachable structure of a carbon dioxide can in a portable carbon dioxide incubator according to a preferred embodiment of the present invention.

7A and 7B, the portable carbon dioxide incubator 10 according to a preferred embodiment of the present invention uses a carbon dioxide can 132 in which a predetermined amount of carbon dioxide is accommodated and sold, and for this purpose, a carbon dioxide supply line 136 And a carbon dioxide supply unit 130 including the solenoid valve 134 and the carbon dioxide can detaching port 140. Here, the carbon dioxide supply line 136 is connected to the carbon dioxide injection nozzle 138 installed to protrude into the culture chamber 30, and is connected to the carbon dioxide can 132. The solenoid valve 134 is installed on the carbon dioxide supply line 136 and operated by a control signal transmitted from the control unit 40 to adjust the amount of carbon dioxide supplied to the culture chamber 30. In addition, the carbon dioxide can detaching port 140 supports the carbon dioxide can 132 so that the carbon dioxide can 132 is connected to the carbon dioxide supply line 136. The carbon dioxide cans 132 applied to the present invention may be applied to those sold by Japan Three Phase Corporation. Since the carbon dioxide can 132 uses carbon dioxide of 99% purity, the carbon dioxide can 132 can be more easily adjusted. The concentration of carbon dioxide is supplied to the culture chamber 30 using the linear solenoid valve 134 which can finely control the supply amount of carbon dioxide. The linear solenoid valve 134 adjusts the control amount of the carbon dioxide concentration measured by the carbon dioxide concentration sensor 112 by purge control.

On the other hand, the portable carbon dioxide incubator 10 according to the preferred embodiment of the present invention constitutes a carbon dioxide can detachment 140 so that the carbon dioxide can 132 can be easily exchanged. The carbon dioxide can detachment opening 140 is a support plate 142 supporting a lower portion of the carbon dioxide can 132, and a carbon dioxide can placed on the support plate 142 by moving the support plate 142 upward by being coupled to the support plate 142. The guiding bar 146 coupled to the moving plate 141 and the long hole 148 formed on the moving plate 141 to guide the moving path of the moving plate 141 to be connected to the carbon dioxide supply line 136. ), The cam hole 152 and the locking jaw 154 is formed, and comprises a lever 150 coupled to the cam bar 147 of the moving plate 141 on the cam hole 152. When the carbon dioxide can detachment 140 is pulled upward by the handle 156 of the lever 150, the lever 150 rotates about the rotation shaft 158 to pull the cam bar 147, thereby the carbon dioxide can 132. By raising the carbon dioxide can 132 is connected to the carbon dioxide supply line 136. When the carbon dioxide can 132 needs to be separated, the cam bar 147 is detached from the catching jaw 154 of the cam hole 152 by lowering the handle 156 of the lever 150 and returned to its original position by the spring 160. Will come back. Of course, such a carbon dioxide can be attached and detached 140 may be applied to a variety of structures applied in a portable burner.

As described above, the portable carbon dioxide incubator according to a preferred embodiment of the present invention is shown in accordance with the above description and drawings, but this is merely described, for example, and various changes and modifications without departing from the technical spirit of the present invention. It will be appreciated by those skilled in the art that this is possible.

According to the portable carbon dioxide incubator according to the present invention, the portability is maximized, and the management of culture conditions and the like is easy, thereby improving the research results and allowing long-distance transfer of microorganisms, eggs, sperm and animal cells, bacteria, etc. This can be very useful. That is, the portable carbon dioxide incubator 10 according to the present invention installs the thermoelectric element 210, which is a Peltier element, and the first and second heat blocks 220 and 230 having excellent heat dissipation so as to be grafted to the thermoelectric element 210, and the constant temperature. By installing the fan 220 and the circulation fan 240, the temperature control in the culture chamber 30 is precisely and effectively made. In addition, by using the can of carbon dioxide can 132 in the form of a constant temperature unit 200 as described above, it is possible to maximize the portability by reducing the size and weight of the incubator. In addition, since the thermoelectric element 210 is applied, there is no vibration and noise compared to the incubator using a conventional heater and a compressor, all four seasons can be used, and it can be used in a place where the temperature change of a car is severe. In addition, to input the set value of the culture chamber 30 to the keypad 72 installed on the case 20, the wireless terminal 76 connected to the wireless communication port 74 and the wired port 78, such as serial or USB Since the wired terminal 80 to be connected can be used, not only various environmental conditions can be given and measured, but also the cultured organisms can be transferred without changing the environment. In addition, the display unit 90 including the display 92, the light emitting diodes 94, 96, 98, and the speaker 100 enables the user to easily know the set value and the current state, thereby enabling efficient incubator management.
