[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 In this embodiment: a split-type pneumatic filling head anti-pollution device includes a feed pipe 1 and a fixing frame 2. A discharge pipe 101 is fixedly installed below the feed pipe 1. Fastening rings 201 are fixedly installed on both sides of the top of the fixing frame 2. A filling head 3 is installed on the internal thread of the fixing frame 2. A sealing component is provided on the filling head 3.

[0023] In this embodiment, the top outer surface of the filling head 3 is provided with an external thread, and the bottom inner surface of the discharge pipe 101 is provided with an internal thread. The top of the filling head 3 can be screwed into the interior of the discharge pipe 101. By setting a fastening ring 201, when the filling head 3 is damaged, the fastening ring 201 can be opened and the filling head 3 can be rotated to disengage it from the discharge pipe 101, so that the damaged filling head 3 can be removed. During installation, the filling head 3 is rotated to screw it into the interior of the discharge pipe 101, and the fastening ring 201 is fixed to the outer surface of the feed pipe 1 to increase the stability of the filling head 3.

[0024] In this embodiment, a rotating groove 301 is provided on the filling head 3, and three sets of equally spaced sliding grooves 302 are provided below the rotating groove 301 on the filling head 3. A limiting ring 303 is fixedly installed above the rotating groove 301 on the filling head 3. By setting the limiting ring 303, the filling head 3 can be limited during installation to prevent the top of the filling head 3 from extending into the inside of the feed pipe 1, thereby affecting the filling process.

[0025] In this embodiment, a rotating ring 4 is installed inside the rotating groove 301 by a thread, a sliding plate 401 is slidably installed inside the sliding groove 302, and a gear groove 402 is provided on the outer side of the sliding plate 401.

[0026] In this embodiment, a groove 403 is provided at the bottom of the inner surface of the rotating ring 4, the top of the sliding plate 401 is rotatably connected to the groove 403, and the sliding plate 401 is in contact with the inner wall of the rotating groove 301.

[0027] In this embodiment, the sealing assembly includes a fixing block 5, a hinge ring 501, and a protective cover 502. The filling head 3 is fixedly installed between every two sets of slides 302. The hinge ring 501 is fixedly installed on the fixing block 5. The protective cover 502 is hinged between every two sets of fixing blocks 5.

[0028] In this embodiment, the inner walls of the three sets of protective covers 502 are all in contact with the outer surface of the filling head 3. When the bottoms of the three sets of protective covers 502 are combined, they are conical. The top outer surface of the protective cover 502 is provided with a rack 503 that matches the gear groove 402. The top of the protective cover 502 is engaged with the slide plate 401. When filling stops, the slide plate 401 moves downward by rotating the rotating ring 4. The gear groove 402 and the rack 503 cooperate to drive the protective cover 502 to rotate around the hinge ring 501, so that the free ends of the three sets of protective covers 502 move to the bottom of the filling head 3 and fit together, thereby sealing the filling head 3 and reducing the time the filling head 3 is exposed to the outside, thus preventing the filling head 3 from being exposed to the outside for a long time and increasing the risk of cross-contamination.

[0029] The working principle and usage process of this utility model are as follows: When filling stops, rotating the rotating ring 4 causes the sliding plate 401 to move downwards. Through the gear groove 402 and the rack 503, the protective cover 502 rotates around the hinge ring 501, so that the free ends of the three sets of protective covers 502 move to the bottom of the filling head 3 and fit together, thereby sealing the filling head 3 and reducing the time the filling head 3 is exposed to the outside, thus preventing the filling head 3 from being exposed to the outside for a long time and increasing the risk of cross-contamination. When filling, rotating the rotating ring 4 in the opposite direction can move the free ends of the three sets of protective covers 502 to the outside of the filling head 3, so that the filling head 3 is exposed, and filling can be carried out.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
