Description

Technical Field

[0001] This utility model relates to the field of liquid filling technology, and in particular to a filling device that prevents splashing and dripping. Background Technology

[0002] Liquid filling refers to the process of quantitatively filling liquid products (such as beverages, pharmaceuticals, cosmetics, edible oils, chemicals, etc.) into containers (such as bottles, cans, bags, barrels, etc.). It is a key link in the packaging industry and is widely used in many industries such as food, pharmaceuticals, daily chemicals, and chemicals.

[0003] Currently, the following problems exist during liquid filling: 1. After each filling, liquid often remains in the filling nozzle. This liquid, which is not filled into the container, will drip onto the surface of the filling ball or the ground. This dripping liquid increases production costs, soils the filling ball, and increases the workload of packaging personnel. 2. Because there is a certain distance between the filling nozzle (i.e., the filling tube) and the filling ball, and the pressure of the liquid in the filling nozzle is relatively high, the impact force generated when the liquid enters the filling ball during filling will cause the liquid to splash, which can easily lead to liquid waste. Utility Model Content

[0004] In response to the shortcomings of the existing production technology, the applicant provides a splash-proof and drip-proof filling device. By improving the filling structure, it ensures that the liquid will not splash during the filling process and that no liquid will remain at the filling outlet after filling, thereby avoiding waste of filling liquid.

[0005] The technical solution adopted in this utility model is as follows: A splash-proof and drip-proof filling device includes: a cavity, a cylinder, a liquid outlet pipe, a first sealing ball, a lifting part, and a second sealing ball. The cavity has a hollow structure. The cylinder is connected to the cavity, and the telescopic end of the cylinder is connected to the liquid outlet pipe. The first sealing ball is placed inside the liquid outlet pipe and located at the outlet end of the liquid outlet pipe, and is movably connected to the liquid outlet pipe. The lifting part is installed inside the cavity and located at the outlet end of the cavity, and is located outside the liquid outlet pipe. The second sealing ball is installed outside the cavity and located at the outlet end of the cavity, and is connected to the liquid outlet pipe.

[0006] Therefore, the opening and closing of the entire filling device is achieved through the cooperation of the first and second sealing balls, a double sealing component. Compared with existing filling methods, this method has a simple structure and is easy to operate. During the filling process, the filling bottle comes into contact with the fixed outlet end, which can effectively prevent liquid splashing. After filling, the double seal of the first and second sealing balls ensures that no liquid remains at the outlet end of the cavity, thus avoiding waste of filling liquid. In addition, the purpose of the first sealing ball sealing from the inside of the liquid outlet tube is to use the weight of the first sealing ball to achieve a seal, thereby reducing the risk of filling liquid leakage. The purpose of the second sealing ball sealing from the outside of the cavity is to use a cylinder to drive the liquid outlet tube to move the second sealing ball, thereby achieving a seal. At the same time, it can ensure that the second sealing ball and the outlet end of the cavity are tightly fitted, thereby further reducing filling liquid leakage and reducing the contact area between the filling liquid and the second sealing ball, so as to achieve the amount of filling liquid adhering to the second sealing ball, thereby further avoiding waste of filling liquid.

[0007] As a further improvement to the above technical solution: the distance between the side of the lifting part near the outlet end of the liquid outlet pipe and the outlet end of the liquid outlet pipe is d. Therefore, since the distance between the side of the lifting part near the outlet end of the liquid outlet pipe and the outlet end of the liquid outlet pipe is d, the accommodating space between the first sealing ball and the second sealing ball can temporarily store residual liquid, further preventing liquid leakage from the cavity and thus further preventing waste of filling liquid. Simultaneously, during the next filling, this temporarily stored residual liquid can be ejected by the movement of the second sealing ball, preventing liquid accumulation. Furthermore, since the distance between the side of the lifting part near the outlet end of the liquid outlet pipe and the outlet end of the liquid outlet pipe is d, the opening and closing of the first and second sealing balls are not simultaneous (i.e., during filling, the second sealing ball opens first, followed by the first sealing ball; during sealing, the first sealing ball closes first, followed by the second sealing ball). The purpose of this is to utilize the time difference between opening and closing to reduce the amount of residual filling liquid, thereby further preventing waste of filling liquid.

[0008] As a further improvement to the above technical solution: a first through hole is provided on the side wall of the cavity, and the liquid outlet pipe is slidably connected to the cavity; the liquid outlet pipe is provided with an L-shaped connecting rod, the L-shaped connecting rod passes through the first through hole and is connected to the second sealing ball, and the cross-sectional shape of the outlet end of the liquid outlet pipe is conical. Therefore, by using an L-shaped connecting rod, the entire filling device can achieve simultaneous movement of the first and second sealing balls (i.e., simultaneously handling the open and closed states) with only one cylinder. This improves the filling efficiency and reduces the overall size of the filling device, enhancing its integration and space utilization. Furthermore, it improves the coordination of the filling and sealing actions of the two sealing components, thus enhancing the anti-splash and anti-leakage effects of the liquid, further improving the overall sealing effect. The conical cross-sectional shape of the outlet pipe guides and positions the movement of the first sealing ball, ensuring a tight fit between the outlet pipe and the first sealing ball, further improving the sealing effect of the entire filling device.

[0009] As a further improvement to the above technical solution: the L-shaped connecting rod is connected to the second sealing ball through a transmission mechanism; the transmission mechanism includes: a first transmission rod and a second transmission rod, one end of the first transmission rod is rotatably connected to the cavity, the other end of the first transmission rod is connected to one end of the second transmission rod, the other end of the second transmission rod is connected to the second sealing ball, the first transmission rod has a sliding groove, the L-shaped connecting rod is inserted into the sliding groove and slidably connected to the first transmission rod. Therefore, since one end of the first transmission rod is rotatably connected to the cavity and the L-shaped connecting rod is slidably connected to the first transmission rod, the linear motion generated by the cylinder can be converted into the arc motion of the second sealing ball (that is, the cylinder drives the L-shaped connecting rod to move closer to or away from the filling ball, and the second sealing ball rotates around one end of the first transmission rod in the direction of moving away from or closer to the cavity). Thus, during filling, the second sealing ball is located diagonally below the cavity outlet end rather than directly below it. The liquid to be filled is directly poured from the cavity outlet end into the filling ball without being blocked by the second sealing ball. On the one hand, this can further avoid splashing during the liquid filling process, and on the other hand, it can avoid liquid waste.

[0010] As a further improvement to the above technical solution: the lifting part includes a lifting block and an annular fixing block. The distance d between the side of the lifting block near the outlet end of the liquid outlet pipe and the outlet end of the liquid outlet pipe is d. The cross-sectional shape of both the upper and lower ends of the lifting block is conical. The lifting block is connected to the annular fixing block through a support rod, and the annular fixing block is connected to the cavity. Therefore, the purpose of the conical cross-sectional shape at the upper end of the lifting block is to guide the filling liquid out from the outlet end of the liquid outlet pipe, thereby further improving the filling efficiency. The purpose of the conical cross-sectional shape at the lower end of the lifting block is, on the one hand, to guide the filling liquid out from the outlet end of the liquid outlet pipe, thereby further improving the filling efficiency; on the other hand, to prevent the filling liquid from accumulating at the lower end of the lifting block.

[0011] As a further improvement to the above technical solution: a sealing block is provided on the side of the cavity away from the cylinder. The sealing block has a second through hole and a third through hole. The second through hole is located at the position of the sealing block relative to the outlet end of the liquid outlet pipe. The cross-sectional shape of the second through hole is conical. The third through hole is located on one side of the second through hole. The first transmission rod passes through the third through hole. One end of the first transmission rod is rotatably connected to the sealing block. The second sealing ball abuts against the sealing block. Therefore, the purpose of designing the second through hole with a conical cross-section is to further store residual liquid, thereby reducing the amount of liquid overflowing when the second sealing ball seals. By designing the third through hole, on the one hand, the third through hole provides movement space for the transmission mechanism and the L-shaped connecting rod, ensuring that the movement of the transmission mechanism, the L-shaped connecting rod and the sealing block do not interfere with each other. On the other hand, the third through hole serves as a communication medium between the filling bottle and the external environment, allowing the gas inside the filling bottle to be discharged during liquid filling (i.e., if the third through hole is not provided, when filling begins, the gas inside the filling bottle can only enter the cavity through the second through hole, which will form air bubbles in the cavity and affect the filling of the liquid).

[0012] As a further improvement to the above technical solution: a placement groove is provided on the side of the sealing block away from the cavity, and both the second through hole and the third through hole are connected to the placement groove. Thus, by designing the placement groove, during filling, the filling bottle is placed in the placement groove and abuts against the sealing block. The placement groove restricts the movement of the filling bottle, ensuring that the second and third through holes are always connected to the filling bottle. The second through hole ensures that the liquid to be filled only flows into the filling bottle and does not leak to the outside, thereby avoiding liquid waste. The third through hole ensures that the filling bottle is always connected to the external environment, allowing gas inside the bottle to be expelled during filling.

[0013] As a further improvement to the above technical solution: a first sealing ring is provided between the lifting block and the sealing block. Thus, the first sealing ring ensures a good sealing effect between the cavity and the sealing block.

[0014] As a further improvement to the above technical solution: a second sealing ring is provided between the cavity and the outlet pipe. Thus, the second sealing ring ensures a good sealing effect between the cavity and the outlet pipe; simultaneously, during the sealing process, since the sealing of the first and second sealing balls does not occur simultaneously, the internal absorption of gas can alleviate the flow of liquid between the outlet pipe and the cavity (i.e., alleviate liquid dripping).

[0015] As a further improvement to the above technical solution: the diameter of the lifting block is d1, and the distance between the outlet ends of the liquid outlet pipe is d2; wherein: Therefore, by limiting the difference between the diameter of the lifting block and the diameter of the outlet end of the liquid outlet pipe, while keeping the diameter d2 of the outlet end of the liquid outlet pipe constant, it is ensured that the accommodating space between the lifting block and the outlet end of the liquid outlet pipe will not be too large or too small. If the accommodating space is too large, the diameter of the lifting block will be too small, which will affect the movement of the lifting block lifting the first sealing ball. If the accommodating space is too small, it will be detrimental to the flow of the filling liquid and will affect the filling efficiency of the liquid.

[0016] The beneficial effects of this utility model are as follows: This invention utilizes the cooperation of a first sealing ball and a second sealing ball as double sealing components to open and close the entire filling device. Compared to existing filling methods, this method is simpler in structure and easier to operate. During the filling process, the filling bottle comes into contact with the fixed outlet end, effectively preventing liquid splashing. After filling, the double seal of the first and second sealing balls ensures that no liquid remains at the outlet end of the cavity, thus avoiding waste of filling liquid. Furthermore, the purpose of the first sealing ball sealing from inside the outlet tube is to achieve a seal using its own weight, reducing the risk of filling liquid leakage. The purpose of the second sealing ball sealing from outside the cavity is to achieve a seal by using a cylinder to drive the outlet tube to move the second sealing ball, thereby achieving a seal. At the same time, it ensures a tight fit between the second sealing ball and the outlet end of the cavity, further reducing filling liquid leakage and minimizing the contact area between the filling liquid and the second sealing ball, thus minimizing the amount of filling liquid remaining on the second sealing ball and further avoiding waste of filling liquid.

[0017] This utility model also has the following advantages: 1. In this invention, the distance d between the side of the lifting part near the outlet end of the liquid outlet pipe and the outlet end of the liquid outlet pipe allows the space between the first sealing ball and the second sealing ball to temporarily store residual liquid, further preventing liquid leakage from the cavity and thus further preventing waste of filling liquid. At the same time, during the next filling, the temporarily stored residual liquid can be flung out by the movement of the second sealing ball, preventing this residual liquid from accumulating. Furthermore, because the distance d between the side of the lifting part near the outlet end of the liquid outlet pipe and the outlet end of the liquid outlet pipe allows the opening and closing of the first and second sealing balls to be non-simultaneous (i.e., during filling, the second sealing ball opens first, followed by the first sealing ball; during sealing, the first sealing ball closes first, followed by the second sealing ball). The purpose of this is to utilize the time difference between opening and closing to reduce the amount of residual filling liquid, thereby further preventing waste of filling liquid.

[0018] 2. This utility model uses an L-shaped connecting rod to enable the entire filling device to simultaneously move the first and second sealing balls (i.e., simultaneously handle the open and closed states) with only one cylinder. This improves the filling efficiency and reduces the overall size of the device, enhancing its integration and space utilization. Furthermore, it improves the coordination of the filling and sealing actions of the two sealing components, thus enhancing the anti-splash and anti-leakage effects of the liquid, further improving the overall sealing effect. The conical cross-sectional shape of the outlet pipe guides and positions the movement of the first sealing ball, ensuring a tight fit between the outlet pipe and the first sealing ball, further improving the sealing effect of the entire filling device.

[0019] 3. This utility model uses a second sealing ring to ensure a good sealing effect between the cavity and the outlet pipe; at the same time, during the sealing process, since the sealing of the first sealing ball and the second sealing ball is not carried out simultaneously, the internal absorption of gas can alleviate the flow of liquid between the outlet pipe and the cavity (i.e., alleviate the dripping of liquid).

[0020] 4. By limiting the difference between the diameter of the lifting block and the diameter of the outlet end of the liquid outlet pipe, this utility model ensures that the accommodating space between the lifting block and the outlet end of the liquid outlet pipe is neither too large nor too small, while keeping the diameter d2 of the outlet end of the liquid outlet pipe constant. If the accommodating space is too large, the diameter of the lifting block will be too small, which will affect the movement of the lifting block lifting the first sealing ball. If the accommodating space is too small, it will be detrimental to the flow of the filling liquid and will affect the filling efficiency of the liquid. Attached Figure Description

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0024] like Figures 1 to 1The diagram shows the preferred embodiment of this utility model. The anti-splash and anti-drip filling device of this embodiment includes: a cavity 1, a cylinder 2, a liquid outlet pipe 3, a first sealing ball 4, a lifting part 5, and a second sealing ball 6. The cavity 1 has a hollow structure. The cylinder 2 is connected to the cavity 1. The telescopic end of the cylinder 2 is connected to the liquid outlet pipe 3. The first sealing ball 4 is placed inside the liquid outlet pipe 3 and is located at the outlet end of the liquid outlet pipe 3, and is movably connected to the liquid outlet pipe 3. The lifting part 5 is installed inside the cavity 1 and is located at the outlet end of the cavity 1. The lifting part 5 is located outside the liquid outlet pipe 3. The second sealing ball 6 is installed outside the cavity 1 and is located at the outlet end of the cavity 1, and is connected to the liquid outlet pipe 3. Therefore, the opening and closing of the entire filling device is achieved through the cooperation of the double sealing components of the first sealing ball 4 and the second sealing ball 6. Compared with the existing filling methods, this method has a simple structure and is easy to operate. During the filling process, the filling bottle abuts against the fixed outlet end, which can effectively prevent liquid splashing. After filling, the double seal of the first sealing ball 4 and the second sealing ball 6 ensures that no liquid remains at the outlet end of the cavity 1, thus avoiding waste of filling liquid. In addition, the purpose of the first sealing ball 4 sealing from the inside of the liquid outlet pipe 3 is to achieve a seal by using the weight of the first sealing ball 4 itself, thereby reducing the risk of filling liquid leakage. The purpose of the second sealing ball 6 sealing from the outside of the cavity 1 is to use the cylinder 2 to drive the liquid outlet pipe 3 to move the second sealing ball 6, thereby achieving a seal. At the same time, it can ensure that the second sealing ball 6 and the outlet end of the cavity 1 are tightly fitted, thereby further reducing the leakage of filling liquid and reducing the contact area between the filling liquid and the second sealing ball 6, so as to achieve the residual amount of filling liquid adhering to the second sealing ball 6, thereby further avoiding waste of filling liquid.

[0025] It should be noted that: I. For example Figure 3 , 4 As shown, the entire filling device being in a sealed state means that the cylinder 2 is in a retracted state, the first sealing ball 4 is in contact with the outlet end of the liquid outlet pipe 3, and the second sealing ball 6 is in contact with the outlet end of the cavity 1 (i.e., the second through hole 801). II. Figure 5 As shown, the filling device being in the filling state means that the cylinder 2 is in the extended state, the first sealing ball 4 is abutted by the lifting part 5 (i.e., the lifting block 501) and lifted away from the outlet end of the liquid outlet pipe 3, and the second sealing ball 6 is located below the outlet end (i.e., the second through hole 801) of the cavity 1.

[0026] For example, the first sealing ball 4 is made of silicone or rubber, and the second sealing ball 6 is made of silicone or rubber.

[0027] In this embodiment, the distance between the side of the lifting part 5 near the outlet end of the liquid outlet pipe 3 and the outlet end of the liquid outlet pipe 3 is d. Therefore, since the distance between the side of the lifting part 5 near the outlet end of the liquid outlet pipe 3 and the outlet end of the liquid outlet pipe 3 is d, the accommodating space between the first sealing ball 4 and the second sealing ball 6 can temporarily store residual liquid, further preventing liquid leakage from the cavity 1 and thus further preventing waste of filling liquid. Simultaneously, during the next filling, this temporarily stored residual liquid can be ejected by the movement of the second sealing ball 6, preventing liquid accumulation. Furthermore, since the distance between the side of the lifting part 5 near the outlet end of the liquid outlet pipe 3 and the outlet end of the liquid outlet pipe 3 is d, the opening and closing of the first sealing ball 4 and the second sealing ball 6 are not simultaneous (i.e., during filling, the second sealing ball 6 opens first, and the first sealing ball 4 opens later; during sealing, the first sealing ball 4 closes first, and the second sealing ball 6 closes later). The purpose of this is to utilize the time difference between opening and closing to reduce the amount of residual filling liquid, thereby further preventing waste of filling liquid.

[0028] It should be noted that: such as Figure 3 , 4 As shown, when the entire filling process is in a sealed state, the distance between the side of the lifting part 5 near the outlet end of the liquid outlet pipe 3 and the outlet end of the liquid outlet pipe 3 is d. This distance d is such that the opening and closing of the first sealing ball 4 and the second sealing ball 6 are not simultaneous (i.e., during filling, the second sealing ball 6 opens first and the first sealing ball 4 opens later; during sealing, the first sealing ball 4 closes first and the second sealing ball 6 closes later).

[0029] In this embodiment, a first through hole 101 is provided on the side wall of the cavity 1, and the liquid outlet pipe 3 is slidably connected to the cavity 1; the liquid outlet pipe 3 is provided with an L-shaped connecting rod 301, which passes through the first through hole 101 and is connected to the second sealing ball 6; the cross-sectional shape of the outlet end of the liquid outlet pipe 3 is conical. Therefore, through the L-shaped connecting rod 301, the entire filling device can achieve the simultaneous movement of the two sealing components, the first sealing ball 4 and the second sealing ball 6, using only one cylinder 2 (i.e., simultaneously handling the open state and simultaneously being in the closed state). In this way, on the one hand, the filling efficiency of the entire filling device can be improved, and the volume of the entire filling device can be reduced, enhancing the integration of the entire filling device and improving space utilization. On the other hand, it can also improve the coordination of the filling action and the coordination of the sealing action of the two sealing components of the entire filling device, thereby improving the anti-splashing effect and anti-leakage effect of the liquid in the entire filling device, and further improving the sealing effect of the liquid in the entire filling device. The purpose of the conical cross-sectional shape of the outlet end of the liquid outlet pipe 3 is to guide and position the movement of the first sealing ball 4, so that the outlet end of the liquid outlet pipe 3 and the first sealing ball 4 can fit tightly, thereby further improving the sealing effect of the entire filling device.

[0030] In this embodiment, the L-shaped connecting rod 301 is connected to the second sealing ball 6 through the transmission mechanism 7. The transmission mechanism 7 includes a first transmission rod 701 and a second transmission rod 702. One end of the first transmission rod 701 is rotatably connected to the cavity 1, and the other end of the first transmission rod 701 is connected to one end of the second transmission rod 702. The other end of the second transmission rod 702 is connected to the second sealing ball 6. The first transmission rod 701 has a sliding groove 703. The L-shaped connecting rod 301 is inserted into the sliding groove 703 and is slidably connected to the first transmission rod 701. Therefore, since one end of the first transmission rod 701 is rotatably connected to the cavity 1 and the L-shaped connecting rod 301 is slidably connected to the first transmission rod 701, the linear motion generated by the cylinder 2 can be converted into the arc motion of the second sealing ball 6 (that is, the cylinder 2 drives the L-shaped connecting rod 301 to move closer to or away from the filling ball, and the second sealing ball 6 rotates around one end of the first transmission rod 701 in the direction of moving away from or closer to the cavity 1). Thus, during filling, the second sealing ball 6 is located diagonally below the outlet end of the cavity 1 rather than directly below it. The liquid to be filled is directly filled from the outlet end of the cavity 1 into the filling ball without being blocked by the second sealing ball 6. On the one hand, this can further avoid splashing during the liquid filling process, and on the other hand, it can avoid liquid waste.

[0031] In this embodiment, the lifting part 5 includes a lifting block 501 and an annular fixing block 502. The distance between the side of the lifting block 501 near the outlet end of the liquid outlet pipe 3 and the outlet end of the liquid outlet pipe 3 is d. The cross-sectional shape of both the upper and lower ends of the lifting block 501 is conical. The lifting block 501 is connected to the annular fixing block 502 through a support rod 503. The annular fixing block 502 is connected to the cavity 1. Therefore, the purpose of the conical cross-sectional shape of the upper end of the lifting block 501 is to guide the filling liquid out from the outlet end of the liquid outlet pipe 3, so as to further improve the filling efficiency of the liquid. The purpose of the conical cross-sectional shape of the lower end of the lifting block 501 is, on the one hand, to guide the filling liquid out from the outlet end of the liquid outlet pipe 3, so as to further improve the filling efficiency of the liquid, and on the other hand, to prevent the filling liquid from accumulating at the lower end of the lifting block 501.

[0032] In this embodiment, a sealing block 8 is provided on the side of the cavity 1 away from the cylinder 2. The sealing block 8 has a second through hole 801 and a third through hole 802. The second through hole 801 is located at the position of the sealing block 8 relative to the outlet end of the liquid outlet pipe 3. The cross-sectional shape of the second through hole 801 is conical. The third through hole 802 is located on one side of the second through hole 801. The first transmission rod 701 passes through the third through hole 802. One end of the first transmission rod 701 is rotatably connected to the sealing block 8. The second sealing ball 6 abuts against the sealing block 8. A placement groove 803 is provided on the side of the sealing block 8 away from the cavity 1. The second through hole 801 and the third through hole 802 are both connected to the placement groove 803. Therefore, the purpose of designing the cross-sectional shape of the second through hole 801 as a cone is to further store residual liquid, thereby reducing the amount of liquid overflowing when the second sealing ball 6 seals. By designing the third through hole 802, on the one hand, the third through hole 802 provides movement space for the transmission mechanism 7 and the L-shaped connecting rod 301, ensuring that the movement of the transmission mechanism 7 and the L-shaped connecting rod 301 does not interfere with the sealing block 8; on the other hand, the third through hole 802 serves as a communication medium between the filling bottle and the external environment, allowing gas to be discharged from the filling bottle during liquid filling (i.e., if the third through hole 802 is not provided, at the start of filling, the gas in the filling bottle can only pass through the second through hole 8). 01 enters the cavity 1, thus forming air bubbles in the cavity 1, affecting the filling of the liquid); by designing the placement groove 803, during filling, the filling bottle is placed in the placement groove 803 and abuts against the sealing block 8. The placement groove 803 restricts the movement of the filling bottle, so that the second through hole 801 and the third through hole 802 are always connected to the filling bottle. The second through hole 801 ensures that the liquid to be filled will only flow into the filling bottle and will not drip to the outside of the filling bottle, thereby avoiding liquid waste. The third through hole 802 ensures that the filling bottle is always connected to the external environment, and the gas in the filling bottle can be discharged during the filling of liquid.

[0033] In this embodiment, a first sealing ring 504 is provided between the lifting block 501 and the sealing block 8. Thus, the first sealing ring 504 (i.e., an O-ring) ensures a good sealing effect between the cavity 1 and the sealing block 8.

[0034] In this embodiment, a second sealing ring 102 is provided between the cavity 1 and the outlet pipe 3. Thus, the second sealing ring 102 (i.e., the O-ring) ensures a good sealing effect between the cavity 1 and the outlet pipe 3; at the same time, during the sealing process, since the sealing of the first sealing ball 4 and the second sealing ball 6 is not performed simultaneously, the internal absorption of gas can alleviate the flow of liquid between the outlet pipe 3 and the cavity 1 (i.e., alleviate the dripping of liquid).

[0035] It should be noted that during sealing, the contact area between the first sealing ball 4 and the outlet of the liquid outlet pipe 3 gradually increases, and the liquid flow gradually decreases until the first sealing ball 4 completely detaches from the lifting block 501, so that the first sealing ball 4 seals with the outlet end of the liquid outlet pipe 3. Subsequently, the second sealing ball 6 seals with the outlet end of the cavity 1. During the entire sealing process, the liquid between the liquid outlet pipe 3 and the cavity 1 will continue to flow out. Since the second sealing ring 102 (i.e., O-ring) is provided between the liquid outlet pipe 3 and the cavity 1, the internal suction of gas during the sealing process can alleviate the flow of liquid between the liquid outlet pipe 3 and the cavity 1 (i.e., alleviate the dripping of liquid).

[0036] In this embodiment, the diameter of the lifting block 501 is d1, and the diameter of the outlet end of the liquid outlet pipe 3 is d2; wherein: Therefore, by limiting the difference between the diameter of the lifting block 501 and the diameter of the outlet end of the liquid outlet pipe 3, while keeping the diameter d2 of the outlet end of the liquid outlet pipe 3 constant, it is ensured that the accommodating space between the lifting block 501 and the outlet end of the liquid outlet pipe 3 will not be too large or too small. If the accommodating space is too large, the diameter of the lifting block 501 will be too small, which will affect the movement of the lifting block 501 lifting the first sealing ball 4. If the accommodating space is too small, it will be detrimental to the flow of the filling liquid and will affect the filling efficiency of the liquid.

[0037] It should be noted that: This is the default value.

[0038] The liquid filling process of this utility model filling device is as follows: First, the storage tank of the liquid to be filled is connected to the inlet end of the liquid outlet pipe 3, and the filling container is installed in the placement groove 803 and abuts against the sealing block 8; then, the driving component is activated, and the liquid outlet pipe 3 is driven to move closer to the filling container through the cylinder 2. With the cooperation of the L-shaped connecting rod 301 and the transmission mechanism 7, the second sealing ball 6 is disengaged from the sealing block 8 and located below the second through hole 801; finally, as the liquid outlet pipe 3 continues to move closer to the filling container, the lifting block 501 is inserted into the outlet end of the liquid outlet pipe 3 and lifts the first sealing ball 4 so that the first sealing ball 4 is disengaged from the outlet end of the liquid outlet pipe 3. The liquid to be filled flows out from the storage tank, passes through the liquid outlet pipe 3 and the cavity 1 in sequence, and flows into the filling container through the second through hole 801, thus realizing the liquid filling operation.

[0039] The sealing process of the filling device of the present invention is as follows: First, the cylinder 2 is started, and the cylinder 2 drives the liquid outlet pipe 3 to move away from the filling container. As the liquid outlet pipe 3 continues to move away from the filling container, the first sealing ball 4 gradually comes into contact with the outlet end of the liquid outlet pipe 3, and the lifting block 501 gradually disengages from the outlet end of the liquid outlet pipe 3. After the lifting part 5 completely disengages from the outlet end of the liquid outlet pipe 3, the first sealing ball 4 seals the outlet end of the liquid outlet pipe 3. Finally, as the liquid outlet pipe 3 continues to move away from the filling container, the second sealing ball 6 is located at the position of the second through hole 801 and comes into contact with the sealing block 8. The first sealing ball 4 and the second sealing ball 6 achieve a double seal.

[0040] In summary, this invention utilizes the cooperation of a first sealing ball 4 and a second sealing ball 6 as double sealing components to achieve the opening and closing of the entire filling device. Compared to existing filling methods, this method has a simpler structure and is easier to operate. During the filling process, the filling bottle abuts against the fixed outlet end, effectively preventing liquid splashing. After filling, the double seal of the first sealing ball 4 and the second sealing ball 6 ensures that no liquid remains at the outlet end of the cavity 1, thus avoiding waste of filling liquid. Furthermore, the first sealing ball 4 enters from inside the liquid outlet pipe 3... The purpose of the sealing is to achieve a seal using the weight of the first sealing ball 4 to reduce the risk of leakage of the filling liquid. The purpose of the second sealing ball 6 sealing from the outside of the cavity 1 is to use the cylinder 2 to drive the liquid outlet pipe 3 to move the second sealing ball 6, thereby achieving a seal. At the same time, it can ensure that the second sealing ball 6 is tightly fitted with the outlet end of the cavity 1 to further reduce leakage of the filling liquid and reduce the contact area between the filling liquid and the second sealing ball 6, so as to achieve the residual amount of filling liquid adhering to the second sealing ball 6, thereby further avoiding waste of the filling liquid.
