DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments 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 in 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.

[0028] Example

[0029] A filling machine leak prevention device, such as Figures 1 to 3 As shown, the anti-leakage device is arranged on the filling head of the filling machine, and comprises a mounting portion 1 and a movable head 11, wherein the mounting portion 1 is connected to the filling head, and the movable head 11 is connected to the mounting portion 1;

[0030] A cavity is arranged inside the mounting part 1, and a connecting head 5 is fixedly connected to the top of the mounting part 1, and the connecting head 5 is communicated with the cavity; the cavity includes a pressure chamber 4 at the top and a mounting chamber 2 at the bottom; a liquid outlet chamber 13 is arranged inside the movable head 11, the bottom of the movable head 11 is open, and one side of the top of the movable head 11 is movably sealed and connected to the mounting chamber 2.

[0031] A liquid filling chamber 7 is provided on one side of the mounting portion 1, and the liquid filling chamber 7 is connected to the pressure chamber 4; a connecting port 15 is provided on the movable head 11 near the top and on the side facing the liquid filling chamber 7; it should be noted here that the position of the connecting port 15 should ensure that the connecting port 15 can be connected to the liquid filling chamber 7 after the movable head 11 moves upward. A contact plate 14 is fixedly connected to the outer side of the movable head 11 near the bottom, and a limit buckle 10 is estimated to be provided at the bottom of the mounting portion 1, and the limit buckle 10 is connected with the contact plate 14. The limit buckle 10 is used to block the contact plate 14 and limit the position of the contact plate 14.

[0032] Specifically, when in use, the leak-proof device is sealed and connected to the filling head and the filling head is opened. Figure 1 As shown, in the initial state, the pressure of the liquid in the pressure chamber 4 will push the movable head 11 downward so that the connecting port 15 and the filling chamber 7 remain disconnected. This self-sealing method can achieve a leak-proof effect. During filling, the movable head 11 of the leak-proof device is aligned with the bottle mouth and pressed down through the filling machine and the filling head. The contact plate 14 first contacts the bottle mouth and then pushes the movable head 11 and the mounting portion 1 to move relative to each other. Figure 3 As shown, the movable head 11 moves upward relative to the mounting portion 1 and connects the connecting port 15 with the liquid filling chamber 7. The liquid enters the pressure chamber 4 from the connecting head 5 and then enters the liquid filling chamber 7. The liquid in the liquid filling chamber 7 enters the liquid outlet chamber 13 after passing through the connecting port 15, thereby achieving filling. After the filling is completed, the filling machine and the filling head lift the anti-leakage device upward, and the pressure of the liquid in the pressure chamber 4 pushes the movable head 11 downward and disconnects the connecting port 15 from the liquid filling chamber 7, thereby preventing excess liquid and leakage.

[0033] In a preferred embodiment, Figure 1 as well as Figure 3 As shown, a limiting ring 6 is fixedly connected to the inner wall of the mounting portion 1 between the pressure chamber 4 and the mounting chamber 2. The limiting ring 6 is used to limit the top position of the movable head 11.

[0034] In a preferred embodiment, Figures 1 to 3 As shown, a compression spring 3 is provided inside the mounting portion 1; one end of the compression spring 3 is connected to the top of the mounting portion 1, and the other end is connected to the inner wall of the mounting portion 1. The compression spring 3 is used to assist the movable head 11 in rebounding. After the filling is completed, the compression spring 3 rebounds and pushes the movable head 11 downward so that the communication port 15 and the filling chamber 7 can be disconnected.

[0035] In a preferred embodiment, Figure 1 as well as Figure 3 As shown, a cleaning channel 9 is provided on the side wall of the mounting portion 1 below the filling cavity 7, and the cleaning channel 9 is connected to the mounting cavity 2; a cleaning joint 8 connected to the cleaning channel 9 is also provided on the outside of the mounting portion 1. The cleaning joint 8 is used to clean the water pipe and the water pump at the other end of the cleaning water pipe. After the filling is completed, the movable head 11 moves downward, at which time the connecting port 15 is connected to the cleaning channel 9, and water is flushed into the cleaning channel 9 through the water pump and the cleaning water pipe, and further flushed into the movable head 11 to clean the inside of the movable head 11.

[0036] In a preferred embodiment, the outer side of the connector 5 is provided with an external thread, and the leak-proof device is threadedly connected to the filling head through the connector 5. The threaded connection can ensure the connection stability between the leak-proof device and the filling head and can also ensure the sealing.

[0037] In a preferred embodiment, Figure 1 as well as Figure 3 As shown, the top of the liquid outlet chamber 13 is an arc-shaped structure. This design is to prevent the residual liquid at the top of the liquid outlet chamber 13 from dripping as much as possible but to flow downward along the inner wall of the movable head 11. This makes it convenient to extract the residual liquid through the exhaust fan.

[0038] In a preferred embodiment, Figure 2 As shown, a drip-proof inner ring 12 is provided in the movable head 11, and the cross-section of the drip-proof inner ring 12 is an arc-shaped structure that bends upward. Further optimized, a plurality of drip-proof inner rings 12 are evenly spaced on the side wall of the liquid outlet cavity 13. Further optimized, four drip-proof inner rings 12 are specifically provided. Further optimized, the drip-proof inner ring 12 is detachably connected to the movable head 11. Through the design of the drip-proof inner ring 12, the residual liquid inside the movable head 11 will flow down the inner wall of the movable head 11 and will be collected in the drip-proof inner ring 12, which prevents the residual liquid from dripping and can effectively improve the leakage prevention effect. By providing multiple drip-proof inner rings 12, the effect of preventing the residual liquid from dripping can be effectively improved. The specific setting of four is the optimal solution obtained according to actual use. The drip-proof inner ring 12 is detachably connected to the movable head 11 to facilitate the removal of the drip-proof inner ring 12 for cleaning.
