Description

Technical Field

[0001] This application relates to the technical field of incubator gas collection, and particularly to a gas sampling box. Background Art

[0002] An incubator needs to control the concentrations of carbon dioxide and oxygen. A carbon dioxide sensor is used to detect the carbon dioxide concentration inside the box and transmit the detection result to controller components such as a control circuit and a solenoid valve. If the detected carbon dioxide concentration inside the box is low, the solenoid valve opens, and carbon dioxide enters the box until the carbon dioxide concentration reaches the set concentration. At this time, the solenoid valve closes, and the carbon dioxide inside the box is cut off, reaching a stable state. Similarly, an oxygen sensor is used to detect the oxygen concentration inside the box and transmit the detection result to controller components such as a control circuit and a solenoid valve. If the detected oxygen concentration inside the box is high, the solenoid valve opens, and nitrogen is used to enter the box until the oxygen concentration reaches the set concentration. At this time, the solenoid valve closes, and the nitrogen inside the box is cut off, reaching a stable state.

[0003] In the prior art, carbon dioxide sensors, oxygen sensors, etc. are directly installed inside the incubator body and do not have the function of high-temperature sterilization. Or when the incubator performs the high-temperature sterilization function, it is necessary to manually disassemble the carbon dioxide sensor and the oxygen sensor, increasing the working procedures.

[0032] In addition, for better illustration of the present application, numerous specific details are given in the following specific embodiments. Those skilled in the art should understand that the present application can also be implemented without some specific details. In some instances, methods, means, elements and circuits well-known to those skilled in the art are not described in detail in order to highlight the gist of the present application.

[0033] Refer to Figure 1 , Figure 2 and Figure 3 , the gas sampling box of the embodiment of the present application is applicable to connecting the gas inlet and gas outlet of an incubator and includes: a sampling box housing 100, a fan 300, a carbon dioxide sensor 400 and an oxygen sensor 500. The sampling box housing 100 is a hollow structure, and a gas detection inlet and a gas detection outlet are provided on the bottom side wall. The gas detection inlet is communicated with the gas outlet of the incubator, and the gas detection outlet is communicated with the gas inlet of the incubator. The fan 300 is arranged inside the sampling box housing 100, between the gas detection inlet and the gas detection outlet, and the direction of the fan 300 is such that the gas detection inlet faces the gas detection outlet, and is used to transport the gas entering from the gas detection inlet to a position where the carbon dioxide sensor 400 and the oxygen sensor 500 can detect. The carbon dioxide sensor 400 and the oxygen sensor 500 are arranged inside the sampling box housing 100, between the fan 300 and the gas detection outlet, and detect the gas pumped into the inside of the sampling box housing 100.

[0034] In this embodiment, the gas sampling box is installed on the electrical installation board 700. The gas in the incubator body is extracted by the fan 300 and enters the chamber with a gas detection inlet. Then, it is transported by the fan 300 to the inside of the chamber with a gas detection outlet. Inside the chamber with the gas detection outlet, a carbon dioxide sensor 400 and an oxygen sensor 500 are installed to complete the concentration detection of the gas. Then, the gas is discharged and returned to the incubator body. In this way, in the ordinary culture mode, through the action of the fan 300, the gas sampling box device realizes the real-time transmission of the gas in the incubator body to the gas sampling box and the detection of the gas. When the incubator is sterilized at high temperature, by stopping the fan 300 from working, the transmission of the gas in the incubator body to the gas sampling box is stopped. Since the temperature of the gas sampling box is much lower than the inside of the incubator body, the protection of the sensor is realized.

[0035] It should be noted that the fan 300, the carbon dioxide sensor 400, and the oxygen sensor 500 in this application are existing realizable technologies, and no more elaboration will be made here.

[0036] In a specific embodiment, the gas sampling box further includes: a partition plate 110. The partition plate 110 is arranged inside the sampling box, between the gas detection inlet and the gas detection outlet. The partition plate 110 separates the gas detection inlet and the detection outlet into a gas inlet cavity and a gas detection cavity. The gas detection inlet is located in the gas inlet cavity, and the gas detection outlet is located in the gas detection cavity. The plate surface of the partition plate 110 is provided with ventilation holes to connect the gas inlet cavity and the gas detection cavity. The fan 300 is arranged on the partition plate 110 and is located in the gas inlet cavity. The air outlet of the fan 300 corresponds to and communicates with the ventilation holes of the partition plate 110.

[0037] In this embodiment, the setting of the partition plate 110 can divide the internal cavity of the sampling box into a gas inlet cavity and a gas detection cavity. And the ventilation holes opened on the partition plate 110 make the air outlet of the fan 300 correspond to the ventilation holes on the partition plate 110, and the gas extracted by the fan 300 from the inside of the incubator is discharged into the gas detection cavity, which can prevent the gas from flowing back to the gas inlet cavity or the incubator.

[0038] Furthermore, by arranging the carbon dioxide sensor 400 and the oxygen sensor 500 in the gas detection cavity of the sampling box, the gas drawn in by the fan 300 can be detected. When the other detection cavity is in a full state, the inspected gas will be discharged back into the incubator again. In this way, the partition has the functions of preventing gas backflow and fixing the fan 300.

[0039] In a specific embodiment, the gas detection inlet and the gas detection outlet are located on the same side of the side wall of the sampling box, and there is a preset distance between the gas detection inlet and the gas detection outlet, which facilitates the arrangement of the partition 110 between the gas detection inlet and the gas detection outlet.

[0040] In a specific embodiment, the sampling box housing 100 is a sealed structure, enabling the gas extracted from the inside of the incubator by the sampling box to be discharged back into the inside of the incubator, and also preventing external infections.

[0041] In a specific embodiment, the gas sampling box further includes: an electrical mounting plate 700, a detection outlet pipe 620, and a detection inlet pipe 610. The electrical mounting plate 700 is located above the incubator, the sampling box is arranged on the top of the electrical mounting plate 700, and through holes are provided on the plate surface of the electrical mounting plate 700. The detection outlet pipe 620 passes through the through hole, and its two ends are respectively communicated with the gas detection outlet and the gas inlet. The detection inlet pipe 610 passes through the through hole, and its two ends are respectively communicated with the gas detection inlet and the gas outlet. Among them, the electrical mounting plate 700 is ingeniously arranged above the incubator, which not only provides a stable support platform for the equipment inside the box, but also realizes the centralized management and convenient maintenance of electrical components.

[0042] Furthermore, in this embodiment, by setting the detection outlet pipe 620 and the detection inlet pipe 610 to communicate the gas detection outlet with the gas inlet, and the gas detection inlet with the gas outlet respectively, a distance can be provided between the electrical mounting plate 700 and the incubator.

[0043] In a specific embodiment, the gas sampling box further includes: a heat-insulating cotton 800. The heat-insulating cotton 800 is filled between the electrical mounting plate 700 and the incubator, which can effectively reduce the heat exchange between the inside of the incubator and the external environment.

[0044] In a specific embodiment, the sampling box housing 100 is made of stainless steel, and is not easily affected by the gas inside the incubator.

[0045] The embodiments of the present application have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments.
