[0028] The blood culture instrument housing air filter device comprises a device body 1, a culture chamber 101, a start knob 102 and a display 103 are respectively provided on the rear side surface of the device body 1, a culture box 1011 is sealed inside the culture chamber 101, an air vent 104 is provided on the right side surface of the device body 1, a filter chamber 105 is provided inside the device body 1, a blower 1051 and a filter plate 1052 are respectively provided inside the filter chamber 105, a coarse filter 1053 and a fine filter 1054 are respectively provided inside the filter plate 1052, and a convenient disassembly mechanism 2 is provided between the filter plate 1052 and the device body 1;

[0029] Specifically, the culture box 1011 is in contact with the inner wall of the culture chamber 101, and a placement hole for holding a blood culture bottle is provided on its rear surface;

[0030] In this embodiment, the culture box 1011 is mainly provided to hold blood culture bottles, and the start knob 102 is mainly provided to transmit a start signal to the device body 1 .

[0031] Specifically, the air holes 104 are symmetrically arranged about the right side surface of the device body 1, and are connected to the filter chamber 105. A screen is arranged inside the air holes 104. The rear surface of the filter plate 1052 fits through the rear surface of the filter chamber 105 and extends outward. The coarse filter 1053, the fine filter 1054 and the filter plate 1052 are integrally formed, and the interior of the filter chamber 105 is respectively connected to the interior of the culture chamber 101 through pipelines.

[0032] In this embodiment, the blower 1051 is mainly used to guide the air in the culture chamber 101, so that the bacteria in the culture chamber 101 can enter the filtration chamber 105 and come into contact with the coarse filter 1053 and the fine filter 1054, and the coarse filter 1053 and the fine filter 1054 can effectively block the bacteria, thereby achieving the filtering effect, which is convenient for protecting the staff.

[0033] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The convenient disassembly mechanism 2 includes a rotating screw 201 and a clamping hole 202. A movable plate 203 is sleeved on the outer surface of the rotating screw 201. A clamping column 204 is fixedly installed on the left side of the movable plate 203. A driving knob 205 is fixedly installed on the right end of the rotating screw 201.

[0034] Specifically, the outer surface of the rotating screw 201 is threadedly connected to the inner wall of the moving plate 203, and the left end of the clamping column 204 movably penetrates the right side surface of the device body 1 and is plugged into the clamping hole 202;
