[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0018] Please refer to Figure 1-2 , an impurity filter for a ventilation pipeline, comprising a filter body, which is composed of an upper shell 1 and a lower shell 2. The upper shell 1 and the lower shell 2 are connected by threads. In this patent, the upper shell 1 uses internal threads and the lower shell 2 uses external threads. It is also possible that the lower shell 2 uses internal threads and the upper shell 1 uses external threads. The main thing is that the threaded structure can facilitate opening for impurity cleaning. Since the filter is used for gas filtration, the sealing performance of the threaded connection needs to be considered. Therefore, a sealing ring 9 is installed at the threaded connection of the upper shell 1 and the lower shell 2.
[0019] The upper shell 1 is provided with an air outlet 6, and the lower shell 2 is provided with an air inlet 7. After the gas from the air inlet 7 enters, it will enter the cavity formed by the upper shell 1 and the lower shell 2, and the impurity filtration is carried out through the filter component installed in the cavity, and then the gas is discharged from the air outlet 7.
[0020] The filtering component includes a baffle 3 with a circular structure and a filter sleeve 5. The baffle 3 is embedded in the groove part inside the upper shell 1, and the air outlet 7 is located inside the groove part. Then, the embedding of the baffle 3 will block the air outlet 7. Therefore, a number of notch parts 8 are provided on the outer edge of the groove part. The notch parts 8 are communicated with the air outlet 6. The gas in the cavity can flow in through the position of the notch parts 8 and be discharged to the air outlet 6. When the gas enters the notch parts 8, the gas has been filtered by the filter sleeve 5. As long as the filter sleeve 5 is located inside the notch parts 8, as Figure 3 shown. After several notch parts 8 are provided, there is no notch part 8 in this view. Then, the groove part can limit the position of the baffle 3. In this patent, the number of notch parts 8 is four.
[0021] On the side of the baffle 3 facing the lower shell, a circular limiting part 4 is provided, and the diameter of the circular limiting part 4 is smaller than the diameter of the baffle 3. The circular limiting part 4 is in contact with the inner wall of one end of the filter sleeve 5. The inner wall of the other end of the filter sleeve 4 is in contact with the convex ring platform 10 on the inner wall of the lower shell 2. And the filter sleeve 5 is of a cylindrical structure. The circular limiting part 4 and the convex ring platform 10 just fit the filter sleeve. Here, the fit means that the two components just contact each other. The purpose is to prevent the left and right displacement of the filter sleeve 5 from affecting the filtration of impurities. After the upper shell 1 and the lower shell 2 are tightened, one end face of the filter sleeve 5 leans against the baffle 3, and the other end leans against the inner wall of the lower shell 2, so that the filter sleeve 5 cannot move up and down. The air inlet 7 is located inside the convex ring platform 10. Then, the gas entering from the air inlet 7 will directly enter the filter sleeve 5, and the filter sleeve 5 filters the impurities in the incoming gas.
[0022] The upper shell 1 and the lower shell 2 are made of a transparent material. The transparent material can facilitate the user to observe the amount of impurities inside the filter. If too many impurities are not processed in time, it will affect the gas discharge volume. This design facilitates the monitoring of impurities.
[0023] In this patent, one filter sleeve 5 can be used. When the length of the filter sleeve 5 is relatively long, a filter sleeve 5 composed of multiple filter sleeves 5 spliced together will be more convenient for cleaning impurities than one filter sleeve 5. The groove part and the connecting part cooperate with each other at the splicing position of any two filter sleeves 5. Just open the groove part and the connecting part, clean the impurities inside a single filter sleeve 5, and after cleaning, just insert the connecting part into the corresponding groove part.
[0024] Working principle: After the gas enters from the air inlet 7, it will directly enter the filter sleeve 5. Due to the existence of the baffle 3 at the head end of the filter sleeve 5, the gas can only flow out through the mesh holes of the filter sleeve 5 and flow to the air outlet 6 through the notch parts 8.
[0025] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
