[0002] The ethylene oxide desorption room is mainly used for the treatment of medical products after EO sterilization. It is an important process equipment to speed up the removal of EO residues and accelerate shipment. It is an important production process for medical manufacturers to improve product quality and competitiveness.

[0003] At present, most of the existing ethylene oxide analyses use natural ventilation analysis, which can basically only meet single or a few similar operation tasks; on the other hand, in actual applications, since the humidity required in the analysis room is usually relatively constant, traditional ethylene oxide analysis rooms need to meet the requirements of heating and maintaining constant circulating humidity while analyzing products. In this way, only single or similar products can be analyzed during analysis. If you want to meet the operation tasks in different temperature ranges, you need to start the machine additionally, which is inefficient especially when facing complex medical equipment systems; therefore, a hot air circulation system is needed to assist the multi-task operation of the analysis room and increase the analysis efficiency.

[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the name of the utility model of this application to avoid blurring the purpose of this section, the abstract of the specification and the name of the utility model, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] Therefore, the purpose of the utility model is to provide a hot air circulation system for an analysis room to solve the problem that the existing ethylene oxide analysis room mentioned in the above background technology can only perform analysis operations on a single or similar product. If it is to meet the operating tasks in different temperature ranges, it needs to be started up additionally, which is inefficient especially when facing a complex medical device system.

[0012] As a preferred solution of the hot air circulation system for a parsing room described in the utility model, the hot air circulation system further includes a master control unit, namely a controller H.

[0013] Compared with the prior art, the beneficial effect of the utility model is that the hot air circulation system of the analysis room can flexibly adjust the humidity of the analysis room with the cooperation of the dehumidification device. At the same time, for example, when the analysis temperature of the analysis object needs to be lowered, the third solenoid valve will lower the valve opening, or keep it fully open according to the actual air volume demand.

[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Figure 1-Figure 3 The following is a schematic diagram of the entire structure of a hot air circulation system for a parsing room of the utility model. Figure 1-Figure 3 A hot air circulation system for an analysis room in the present embodiment comprises an analysis room body 1 and a corresponding hot air circulation system, the hot air circulation system comprising a heater 2 arranged on the upper part of the analysis room body 1, the air inlet end of the heater 2 is connected to the air outlet end of the fan 3, the air inlet end of the fan 3 is connected to the total air outlet of the hot air circulation system to which the analysis room body 1 belongs through the arranged return pipe 4, the return pipe 4 is also provided with a dehumidification device, the air outlet end of the heater 2 is connected to the supply air pipe 6, the analysis room body 1 has an air supply channel 7 connected to the other end of the supply air pipe 6, a plurality of units of hot air output pipelines are arranged on one side of the supply air channel 7, each hot air output pipeline has an air supply branch pipe 8 connected to the air supply channel 7, a third solenoid valve 81 is arranged on the air supply branch pipe 8, and a cold air pipeline 82 with adjustable air volume is connected to the air outlet direction of the third solenoid valve 81 on the air supply branch pipe 8.

[0022] The dehumidification device includes a dehumidifier 5 whose air inlet and air outlet are connected in series with a return pipe 4. The return pipe 4 is also provided with a flow regulating pipe 51 with one end connected to the air inlet direction of the dehumidifier 5 and the other end connected to the air outlet direction of the dehumidifier 5. A first solenoid valve 52 is provided on the return pipe 4 and adjacent to the air inlet of the dehumidifier 5. A second solenoid valve 53 cooperating with the first solenoid valve 52 is provided on the flow regulating pipe 51. When in use, in order to keep the analysis room in a constant humidity environment, for example, when the humidity is too high, the first solenoid valve 52 is fully open or the valve port is adjusted to a larger value, while the second solenoid valve 53 is closed and the valve port is adjusted to a smaller value. When the humidity is too low, the first solenoid valve 52 is closed and the second solenoid valve 53 is opened. At this time, the analysis room can cooperate with the humidification device to supplement the humidity. When the humidity is at the set normal value, the first solenoid valve 52 is closed and the second solenoid valve 53 is opened, thereby realizing flexible adjustment of the humidity, without the need for the heater 2 and the heating system to participate in the humidity adjustment, thereby ensuring the continuous temperature and analysis efficiency of the hot air circulation.

[0023] A temperature sensor 61 is also provided on the air supply pipe 6. The temperature sensor 61 can monitor the temperature of the hot air discharged from the air supply pipe 6 in real time. The temperature value of the hot air temperature is generally constant and in a relatively high state, which can facilitate the flexible adjustment of the subsequent hot air output pipeline.

[0024] In this embodiment, in order to enable each hot air output pipeline to independently adjust the temperature according to different analytical objects, an auxiliary fan 821 and a stop valve are further provided on the cold air pipeline 82, and a temperature sensor 83 is further provided on the air outlet port of the air supply branch pipe 8.

[0027] It can be understood that the hot air circulation system also includes a master control unit, namely, a controller H. The hot air circulation system of the analysis room should be equipped with a master control unit, which is referred to as controller H for short. The staff can uniformly control and set the hot air circulation system according to the hot air state and the needs of the analysis object, which brings convenience to the use of the hot air circulation system.

[0028] In summary, in a hot air circulation system for an analysis room of the present embodiment, when in use, when the analysis temperature of the analysis object needs to be lowered, the third solenoid valve 81 will lower the valve opening, or keep it fully open according to the actual air volume demand. At this time, the auxiliary fan 821 will be turned on and the purified normal temperature air or cold air will be sucked into the cold air duct 82 through the cold air duct 82, and the hot air in the supply air branch 8 will be appropriately cooled. The auxiliary fan 821 here can adopt a variable frequency adjustable form, so that the air inlet can be flexibly controlled according to actual needs, and the cold air duct 82 should also be equipped with at least a stop valve, which can close the cold air duct 82 when cold air is not needed. During this process, the temperature sensor 83 will monitor the hot air temperature at the outlet of the supply air branch 8 in real time, and the control unit will adjust the third solenoid valve 81, the auxiliary fan 821, etc. accordingly, thereby achieving the purpose of independent temperature control according to different analysis objects, and multi-task analysis can be performed simultaneously.
