[0037] like Figures 1 to 5As shown, a filling device is provided in this embodiment, which includes a material cylinder 10, a filling member 20 and a sliding sleeve 30. The material cylinder 10 has a receiving chamber 11, the filling member 20 is fixedly connected to the bottom wall of the material cylinder 10, and one end of the filling member 20 is located in the receiving chamber 11, and the other end of the filling member 20 extends out of the material cylinder 10. The filling member 20 is provided with a filling channel 211, and the filling channel 211 can connect the receiving chamber 11 with the outside; the sliding sleeve 30 is slidably arranged on the outside of the filling member 20. The sliding sleeve 30 is provided with a transition cavity 31 on the peripheral wall, and the transition cavity 31 is communicated with the filling channel 211. The side wall of the sliding sleeve 30 is provided with a flow port 32, and the transition cavity 31 is communicated with the accommodating cavity 11 through the flow port 32. The sliding sleeve 30 has a feeding position and a discharging position. When the sliding sleeve 30 is at the feeding position, the material in the accommodating cavity 11 can enter the transition cavity 31 through the flow port 32. When the sliding sleeve 30 is at the discharging position, the material in the transition cavity 31 can enter the filling channel 211. Specifically, in this embodiment, the accommodating chamber 11 of the material cylinder 10 is used to store materials. When filling materials, the sliding sleeve 30 is first placed in the feeding position, and the liquid level of the material in the accommodating chamber 11 is lower than the liquid level of the circulation port 32, so that the material can enter the transition chamber 31 of the sliding sleeve 30 from the circulation port 32. Then, the sliding sleeve 30 slides upward along the filling member 20, and the transition chamber 31 moves upward relative to the top of the filling member 20, so that the liquid level of the material in the transition chamber 31 reaches the filling member 20, so that the material in the transition chamber 31 can enter the filling channel 211 and enter the filling container through the filling channel 211. In this filling device, the sliding sleeve 30 and the filling member 20 that are in contact with the material are both arranged inside the material cylinder 10. The inside of the material cylinder 10 is a sterile environment, which can ensure the cleanliness and sterility of the material, and thus ensure the product quality.

[0038] For further information, please refer to Figure 2 and Figure 3 The filling device includes a blocking member 40, which is fixedly connected to the sliding sleeve 30. When the sliding sleeve 30 is in the feeding position, the blocking member 40 blocks the outlet 212 of the filling channel 211. Specifically, in this embodiment, the blocking member 40 is fixedly connected to the sliding sleeve 30, and the blocking member 40 is located in the transition chamber 31 and is coaxially arranged with the filling channel 211. When the sliding sleeve 30 slides along the filling member 20, the blocking member 40 slides in the filling channel 211, and when the sliding sleeve 30 is in the feeding position, the blocking member 40 blocks the outlet 212 of the filling channel 211. This arrangement blocks the filling channel 211 when no filling is performed, which can reduce the risk of external impurities entering the filling channel 211, thereby further improving the cleanliness of the material and improving the product quality.

[0039] Furthermore, the circulation opening 32 is square, and the bottom wall of the circulation opening 32 is horizontally arranged. Specifically, in this embodiment, the bottom wall of the circulation opening 32 is horizontally arranged, which can not only make the material in the accommodating chamber 11 conveniently enter the transition chamber 31, but also make the liquid level of the material in the transition chamber 31 horizontal, and can obtain the total amount of the material contained in the transition chamber 31 through the height of the bottom wall of the circulation opening 32 of the transition chamber 31, and control the filling amount of the material of this filling by controlling the rising height of the sliding sleeve 30, thereby improving the convenience and flexibility of filling.

[0040] Specifically, in this embodiment, Figure 4 As shown, when the bottom wall of the transition chamber 31 is flush with the top of the filling member 20, the filling volume of the filling device is maximum.

[0041] Further, a plurality of flow openings 32 are provided, and the plurality of flow openings 32 are spaced apart on the side wall of the sliding sleeve 30 around the axial direction of the sliding sleeve 30. Specifically, in this embodiment, the plurality of flow openings 32 are spaced apart on the side wall of the sliding sleeve 30 around the axial direction of the sliding sleeve 30, so that the material can enter the transition chamber 31 through the plurality of flow openings 32 at the same time, thereby improving the feeding speed of the material and ensuring the filling efficiency.

[0042] Further, the filling device further includes a driving member 50, which is disposed at the top of the material cylinder 10, and is in transmission connection with the sliding sleeve 30, and is used to drive the sliding sleeve 30 to slide relative to the filling member 20.
