[0030] The following will be combined with the drawings in the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] Reference Figure 1 , Figure 3 and Figure 5 The utility model provides an embodiment: an organic matter sampling device with a screening function, comprising a shell 1, a partition 2 is fixedly connected to the inside of the shell 1, a filter screen 3 is embedded in the middle of the partition 2, a gas collecting hood 4 is fixedly connected to one side of the shell 1, a connecting pipe 5 is fixedly connected to one side of the gas collecting hood 4, a threaded end of the connecting pipe 5 is threadedly connected to a collecting bottle 6, an air pump 7 is fixedly connected to the outer wall of the shell 1, an air outlet pipe 8 is fixedly connected to the output end of the air pump 7, the air outlet pipe 8 is arranged in a zigzag shape, one end of the air outlet pipe 8 is located inside the shell 1, and the opening of the air outlet pipe 8 faces the collecting bottle 6, and a fixed component is arranged on the outside of the filter screen 3. The partition 2 is arranged in a cross shape, and four filter screens 3 and collecting bottles 6 are arranged.
[0032] During use, when it is necessary to collect exhaust gas, the shell 1 is placed close to the exhaust gas source, and the air pump 7 is driven to make the gas flow out along the exhaust pipe 8. Since the exhaust pipe 8 is arranged in a zigzag shape, and the open end of the exhaust pipe 8 faces the collecting bottle 6, after the air flow is ejected from the exhaust pipe 8, the air around the exhaust pipe 8 will be driven to flow with the air flow, and then the gas on the rear side of the shell 1 enters the collecting bottle 6 and dissipates. At this time, the air on the left side of the shell 1 is dissipated, and the gas on the right side of the shell 1 enters the left side of the shell 1, thereby generating suction to collect the exhaust gas, and the air pump 7 is installed on the outside of the shell 1, so that it can prevent debris in the air flow from entering the air pump 7 and causing damage to it.
[0033] Reference Figure 1 and Figure 2 An air intake cover 9 is fixedly connected to the other side of the shell 1.
[0034] Exhaust gas can be guided into the interior of the housing 1 via the air inlet hood 9 .
[0035] Reference Figure 1 , Figure 3 and Figure 4 The fixing assembly includes a fixing frame 10 and a handle 11. The handle 11 is installed on one side of the outside of the fixing frame 10. The filter 3 is embedded in the inside of the fixing frame 10. The fixing frame 10 is located inside the housing 1. A card slot 13 is provided inside the housing 1, a groove 12 is provided on one side of the partition 2, and the top and bottom of the outer wall of the fixing frame 10 are located inside the groove 12 and the card slot 13 respectively.
[0036] The exhaust gas can be divided into four parts by the partition 2 and finally enter into four collecting bottles 6 respectively, and the blocked particles will fall on the inner bottom of the shell 1, and the fixing frame 10 can be pulled out from the inside of the shell 1 by pulling the handle 11. At this time, the filter 3 can be removed together, and then the filter 3 can be cleaned. During installation, the fixing frame 10 is aligned with the card slot 13 and the groove 12, and then the fixing frame 10 is inserted into the inside of the shell 1, so as to facilitate the loading and unloading of the filter 3 and facilitate the cleaning of the filter 3 later.
[0037] Reference Figure 1 , Figure 2 and Figure 3 A collecting bucket 14 is fixedly connected to the middle of the bottom surface of the shell 1, a collecting pipe 15 is fixedly connected to the bottom of the collecting bucket 14, and a sealing cover 16 is connected to the bottom threaded end of the collecting pipe 15. A through hole is provided at the bottom of the shell 1, and the collecting bucket 14, the through hole and the shell 1 are interconnected. A rubber sleeve 17 is fixedly connected to the outside of the collecting pipe 15.
[0038] The device can be held by hand through the collecting tube 15 and the rubber sleeve 17, and the particles blocked by the filter 3 will fall to the inner bottom of the shell 1, and finally fall into the collecting bucket 14 through the through hole. The collecting bucket 14 can guide the particles into the collecting tube 15. When use is over, the collected particles can be taken out by rotating and removing the sealing cover 16.
[0039] Working principle: During use, when it is necessary to sample the exhaust gas, the air inlet hood 9 is brought close to the exhaust gas source, and the air pump 7 is driven to make the gas flow out along the exhaust pipe 8. Since the exhaust pipe 8 is arranged in a zigzag shape, and the open end of the exhaust pipe 8 faces the collecting bottle 6, after the air flow is ejected from the exhaust pipe 8, the air around the exhaust pipe 8 will be driven to flow with the air flow, so that the gas on the rear side of the shell 1 enters the collecting bottle 6 and disperses. At this time, the air on the right side of the shell 1 disperses, and the gas on the left side of the shell 1 enters the right side of the shell 1, thereby generating suction to collect the exhaust gas, and when the exhaust gas enters the shell 1, the particulate matter in the exhaust gas can be blocked by the filter 3, and the particulate matter can be separated by the filter 3. The plate 2 can divide the exhaust gas into four parts, and finally enter the four collecting bottles 6 respectively. The blocked particles will fall on the inner bottom of the shell 1, and finally fall into the collecting bucket 14 through the through hole. The collecting bucket 14 can guide the particles into the collecting tube 15. When use is over, the collected particles can be taken out by rotating and removing the sealing cover 16, and the fixing frame 10 can be pulled out from the inside of the shell 1 by pulling the handle 11. At this time, the filter 3 can be removed together, and then the filter 3 can be cleaned. When installing, align the fixing frame 10 with the slot 13 and the groove 12, and then insert the fixing frame 10 into the inside of the shell 1, so as to facilitate the removal of the filter 3, which is beneficial to the cleaning of the filter 3 later.
