[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Example 1:

[0030] Reference Figure 1-5 The poultry house microbial aerosol sampling device includes a sampling box 1, and also includes: a sampling bottle 2, which is slidably connected to the sampling box 1, and the bottom of the sampling bottle 2 is connected to an air intake pipe 203; a filter screen 201, which is installed on the side wall of the sampling bottle 2, and the filter screen 201 is arranged in an annular shape; a filter screen 202, which is installed in the sampling bottle 2; a rotating shaft 301, which is rotatably connected to the sampling bottle 2, and a fan blade 302 is fixedly connected to the rotating shaft 301. When the air intake pipe 203 inhales, the external gas will enter the sampling bottle 2 through the filter screen 201, and the air flow will drive the fan blade 302 to rotate, and finally the gas passes through the air intake pipe 20 3 discharge; multiple groups of bristles 304 are fixedly connected to the rotating shaft 301, and the bristles 304 are against the filter 201; a vibration component is arranged in the sampling box 1; a gas cleaning component is arranged on the rotating shaft 301, and multiple groups of mounting rods 303 are fixedly connected to the rotating shaft 301, and the bristles 304 are fixedly connected to the mounting rods 303. The end of the rotating shaft 301 away from the fan blades 302 passes through the sampling bottle 2, and a rotating handle 3011 is fixedly connected to the through end of the rotating shaft 301. A telescopic rod 101 is fixedly connected in the sampling box 1, and the sampling bottle 2 is fixedly connected to the telescopic end of the telescopic rod 101.

[0031] The sampling box 1 in this device is an equipment box with a built-in collection and sampling function, the specific model is LB-NS2112, and an air pump is provided inside, which is connected to the suction pipe 203, and the air outlet end of the air pump is connected to the internal collection and sampling device. Specifically, when in use, the air pump is used to create a negative pressure in the sampling bottle 2, thereby inhaling the external gas, so that the gas finally enters the collection and sampling device.

[0032] Specifically, when in use, the device is placed in a poultry house, and the sampling bottle 2 is extended from the sampling box 1 through the telescopic rod 101, and then the air pump is started. The air pump creates a negative pressure in the sampling bottle 2, and then the sampling bottle 2 continuously inhales the external gas. At this time, the gas first passes through the filter 201, and the filter 201 filters the larger impurities in the gas, and then the gas enters the sampling bottle 2. The flow of the gas will cause the fan blades 302 to rotate, and then the gas will be filtered again through the filter 202, and finally enter the air pump through the suction pipe 203 and enter the collection sampling device.

[0033] It should be noted that the aperture of filter 202 is consistent with the aperture of filter 1 201, and is used for secondary filtration. Filter 202 can be selected according to needs, or it can be not set. If it is set, it needs to be opened and cleaned regularly to avoid the accumulation of impurities generated by secondary filtration. In this embodiment, filter 202 is set to perform secondary filtration on the gas through filter 202. Because the gas filtered by filter 1 201 is unlikely to carry impurities, or carries very few impurities, but filter 202 can play a role of re-filtration, thereby improving the accuracy of subsequent sampling, so filter 202 is installed.

[0034] The rotation of the fan blades 302 causes the rotating shaft 301 to rotate, thereby causing the bristles 304 to clean the filter 201. The bristles 304 are fine brushes that can extend into the filter holes of the filter 201 for cleaning.

[0035] When the rotating shaft 301 rotates, the knocking assembly will continuously vibrate, thereby loosening the debris on the filter 201 through vibration, making it easier for the bristles 304 to brush away the debris;

[0036] When not in use, the rotating handle 3011 can be manually rotated to rotate the rotating shaft 301 and the bristles 304 can be used for manual cleaning.

[0037] Example 2:

[0038] Reference Figure 1-5 , a poultry house microbial aerosol sampling device is basically the same as Example 1, and further: the vibration component includes an auxiliary rod 306, a spring member 307, a knocking block 308, and a protrusion 204, the auxiliary rod 306 is fixedly connected to the rotating shaft 301, and an empty opening is opened on the end of the auxiliary rod 306 away from the rotating shaft 301, the spring member 307 is installed in the empty opening, and the knocking block 308 is slidably connected in the empty opening, the spring member 307 is connected to the knocking block 308, and multiple groups of protrusions 204 are arranged at equal intervals on the inner wall of the sampling bottle 2, and vibration can be generated by the contact between the knocking block 308 and the protrusion 204.

[0039] The vibration assembly utilizes the contact between the knocking block 308 and the protrusion 204 to continuously generate vibrations in cooperation with the spring member 307, thereby improving the cleaning ability through vibration.

[0040] Example 3:

[0041] Reference Figure 1-5 The poultry house microbial aerosol sampling device is basically the same as that of Example 1, and further: the gas cleaning component includes an outlet pipe 305, and an air blowing pipe 3051 is rotatably connected to the rotating shaft 301, the air inlet end of the air blowing pipe 3051 is located outside the sampling bottle 2, and the air blowing pipe 3051 is communicated with the air outlet pipe 305, and the air outlet pipe 305 is used to blow air into the filter 201.

[0042] When not in use, the handle 3011 can be manually rotated to rotate the rotating shaft 301, and air can be blown into the air outlet pipe 305 through the air pipe 3051 with the mouth, so that the bristles 304, the vibration component and the air pipe 3051 can be cleaned synchronously.

[0043] The utility model can effectively remove impurities adhering to the filter screen 201 by setting the bristles 304, the vibration component and the gas cleaning component. At the same time, the vibration and the air flow back-blowing method can further discharge the debris and avoid the accumulation of debris affecting the accuracy of sampling.

[0044] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
