[0028] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1: In the prior art, when performing edible oil filling tasks for a long time, the nozzle of the filling head may be clogged due to the solidification of oil stains, resulting in a reduced amount of oil filled or poor oil discharge, thereby affecting the working efficiency of the filling machine. Faced with the problem of nozzle clogging, staff usually need to replace the clogged nozzle.

[0030] Therefore, in order to improve the replacement efficiency of the blocked nozzle, reduce the impact on the working efficiency of the filling machine, and realize the function of quickly replacing the nozzle, the utility model discloses a nozzle assembly that is easy to disassemble. Figure 3 and Figure 6, comprising a filling head 4 and a nozzle 5 sleeved in the filling head 4, wherein a groove is provided on the outer wall of the nozzle 5, a spring piece 8 is provided in the groove, the spring piece 8 is in a U-shaped structure as a whole, and the side of the spring piece 8 facing the output end of the nozzle 5 is higher than the side of the spring piece 8 facing the input end of the nozzle 5, and the end point of the spring piece 8 facing the output end of the nozzle 5 is provided with a stop plate perpendicular to the opening of the groove, the input end of the nozzle 5 is sleeved in the output end of the filling head 4, and a through groove 9 corresponding to the spring piece 8 is provided on the filling head 4;

[0031] In this embodiment, when the nozzle 5 needs to be assembled into the filling head 4, the user can insert the input end of the nozzle 5 into the output end of the filling head 4. As the nozzle 5 is continuously pushed, the inner wall of the filling head 4 will squeeze the spring piece 8, so that the spring piece 8 will be pressed into the groove. When the spring piece 8 moves to the position of the through groove 9, the spring piece 8 will pop out due to the loss of pressure and penetrate into the through groove 9. At the same time, the abutment plate will abut against the inner wall of the through groove 9 to prevent the nozzle 5 from sliding down, thereby achieving the purpose of fixing the nozzle 5. In this way, the process of installing the nozzle 5 can be more concise, and the nozzle 5 can be assembled without the help of other tools.

[0032] When the clogged nozzle 5 needs to be removed, the user can continue to press the spring piece 8 so that the spring piece 8 can be pressed into the groove again. Then the user only needs to pull the nozzle 5 out of the filling head 4 while continuing to press the spring piece 8 to complete the disassembly.

[0033] In this embodiment, in order to enable the nozzle 5 to spray oil smoothly, an oil pipe interface 6 for introducing oil is provided on the input end of the filling head 4. By connecting the external oil pipe to the oil pipe interface 6, edible oil can enter the filling head 4 along the oil pipe interface 6, and then the oil can be sprayed out through the nozzle 5.

[0034] Example 2: Based on Example 1, in order to reduce the misalignment between the spring piece 8 and the through slot 9 when assembling the nozzle 5, and to avoid the rotation or shaking of the nozzle 5 in the filling head 4, refer to Figure 4 and Figure 5 The present invention further includes a guide block 11 and a guide groove 12 for guiding and limiting. Specifically, a guide groove 12 is further provided on the outer wall of the nozzle 5, and a guide block 11 corresponding to the guide groove 12 is provided in the output end of the filling head 4;

[0035] In this embodiment, through the above structure, when the user inserts the nozzle 5 into the filling head 4, the user can align the guide groove 12 on the outer wall of the nozzle 5 with the guide block 11 in the filling head 4, and then slowly push the nozzle 5 along the direction of the guide groove 12 until the nozzle 5 is fully installed. This improves the accuracy of the nozzle 5 during installation and greatly reduces the possibility of the nozzle 5 rotating or shaking in the filling head 4, thereby improving the stability and reliability of the overall structure.

[0036] Illustratively, the four guide grooves 12 and the four guide blocks 11 are respectively distributed in a cross shape on the outer wall of the nozzle 5 and the inside of the filling head 4, so that the nozzle 5 can be evenly stressed during installation and can be accurately aligned with the guide blocks 11, further improving the convenience and stability of installation. At the same time, it can also enhance the connection strength between the nozzle 5 and the filling head 4, so that the nozzle 5 is not easy to loosen or fall off during the filling process, which helps to have a beneficial effect on the continuity and stability of the filling operation.

[0037] Example 3: Based on any one of Example 1 and Example 2, in order to further improve the stability of the nozzle 5 in the filling head 4, refer to Figure 7 The present invention further includes a support member for supporting the nozzle 5. Specifically, a receiving platform 13 is provided between the output end and the input end of the filling head 4. The receiving platform 13 is provided with a support member for supporting the nozzle 5 on the side facing the output end. The support member includes two upper and lower parallel retaining rings 14 and a spring 15 provided between the two retaining rings 14.

[0038] In this embodiment, when the input end of the nozzle 5 enters the interior of the filling head 4, the input end of the nozzle 5 will fit with one of the retaining rings 14 of the support. As the nozzle 5 continues to penetrate deeper into the filling head 4, the retaining ring 14 that fits with the nozzle 5 will move toward the retaining ring 14 at the other end under the contraction of the spring 15. Then, when the nozzle 5 penetrates to the specified position and the spring sheet 8 is engaged with the through groove 9, the spring 15 will release the pressure, so that the retaining ring 14 and the spring sheet 8 can tightly press the nozzle 5, so that it is stably fixed in the filling head 4.

[0039] At the same time, in another embodiment, when the nozzle 5 needs to be removed from the filling head 4, the user can continue to push the nozzle 5 toward the receiving platform 13. At this time, as the nozzle 5 continues to go deeper, the spring piece 8 engaged in the through groove 9 will be squeezed into the groove again by the inner wall of the filling head 4. Then the user only needs to press the finger on the through groove 9 and then pull out the nozzle 5 in the opposite direction to complete the disassembly operation. In this embodiment, the user does not need to continuously press the spring piece 8, which makes the process of disassembling the nozzle 5 more labor-saving.

[0040] In this embodiment, a snap ring 7 for receiving the spring sheet 8 is provided between the through groove 9 and the opening of the output end of the filling head 4. The filling head 4 is provided with a thread 10 for fixing the snap ring 7. When the spring sheet 8 is engaged with the through groove 9 and the abutment plate abuts against the inner wall of the through groove 9, the snap ring 7 can fit with the abutment plate to play a supporting role.

[0041] At the same time, the provision of the thread 10 makes it easier to disassemble the snap ring 7, thereby improving the replacement efficiency of the snap ring 7.

[0043] In one embodiment, by adopting the above-mentioned scheme, the working principle of the filling machine is that during the filling operation, when edible oil or other liquid to be filled is connected to the oil pipe interface 6 through an external oil pipe, the liquid will flow smoothly into the filling head 4 and then be sprayed out through the nozzle 5 to perform the filling operation.

[0044] Due to the clamping and supporting structure between the nozzle 5 and the filling head 4, that is, the cooperation between the spring sheet 8 and the through groove 9, and the elastic support of the retaining ring 14 and the spring 15 in the support member, the stability and reliability of the nozzle 5 during the filling process are improved.

[0045] In addition, the setting of the guide block 11 and the guide groove 12 further improves the convenience and accuracy of the installation of the nozzle 5. When installing the nozzle 5, the user only needs to simply align the guide groove 12 with the guide block 11 and gently push it in along the guide direction to complete the installation.

[0046] In the overall structure of the filling machine, the top seat 3 bears the weight of the nozzle assembly, while the conveyor belt 2 on the conveyor platform 1 can continuously transport the containers to be filled to the bottom of the nozzle 5 for filling operations. The support column plays a role in supporting and stabilizing the entire filling machine, helping it to prevent shaking or tilting during operation.
