[0002] Shampoo is a basic hair care cosmetic specifically designed to cleanse the hair and scalp. Its core function is to remove oil, sweat, dandruff, and external pollutants. In the shampoo production process, filling equipment is used to fill shampoo into containers such as plastic bottles. After filling, a small amount of shampoo remains inside the filling head structure. During the production line's idle period, this residual shampoo is prone to denaturation, causing it to mix with the undenatured shampoo during subsequent fillings, thus affecting the quality of the final shampoo product.

[0003] It should be noted that the above content is only used to help understand the technical solution of this utility model, and does not represent an admission that the above content is prior art. Utility Model Content

[0007] A blocking assembly is disposed in the infusion channel and fixedly connected to the first tube body. A first protruding edge is provided circumferentially on the outer side of the second tube body. The first protruding edge abuts against the container opening to drive the second tube body to slide relative to the first tube body from a first position to a second position. When the second tube body is in the first position, the blocking assembly blocks the filling port; when the second tube body is in the second position, the blocking assembly releases the blockage from the filling port.

[0008] The gas injection assembly is used to inject gas into the infusion channel toward the filling port.

[0009] In one embodiment, an injection tube is installed at the end of the first tube body away from the second tube body, and the injection tube is in communication with the infusion channel;

[0010] In one embodiment, the gas injection assembly includes a gas injection tube, which is installed at the end of the first tube body away from the second tube body, and the gas injection tube is in communication with the infusion channel.

[0011] In one embodiment, the air injection tube is located above the liquid injection tube; the liquid injection tube and / or the air injection tube are inclined toward the filling port.

[0012] In one embodiment, the sealing assembly includes a connecting post and a sealing element. The connecting post is coaxially arranged with the infusion channel. One end of the connecting post is fixedly connected to the first tube body, and the other end of the connecting post is connected to the sealing element, which is used to seal the filling port.

[0013] In one embodiment, the filling port is located on the side of the second tube body and is inclined downward; the side wall of the middle part of the sealing member is used to fit tightly against the inner wall of the second tube body; the top of the sealing member has a structure that is narrow at the top and wide at the bottom to form a guide slope; when the second tube body is in the second position, the guide slope of the sealing member and the inclined surface of the filling port are on the same slope.

[0014] In one embodiment, a second protruding edge is provided on the outer side of the second tube body and below the filling port. The second protruding edge can be inserted into the container along with the second tube body. The second protruding edge has a triangular structure, and the inclined surface of the second protruding edge is on the same inclined surface as the inclined surface of the filling port. The free end angle of the second protruding edge is set at an acute angle.

[0015] In one embodiment, the first tube has a cylindrical insertion portion, and the second tube has a cylindrical sleeve portion, the sleeve portion being slidably fitted onto the insertion portion, and a seal being formed between the inner sidewall of the sleeve portion and the outer sidewall of the insertion portion; and the filling head structure further includes a spring member, the spring member being fitted onto the outer side of the sleeve portion, and the two ends of the spring member abutting against the protrusions of the first tube and the second tube respectively.

[0016] In one embodiment, the insertion part is provided with a limiting groove, the groove direction of which is in the same direction as the sliding path of the second tube body relative to the first tube body; the sleeve part is provided with a limiting block, the limiting block being slidably connected in the limiting groove;

[0017] In one embodiment, a sealing layer is provided on the side of the insertion portion that contacts the sleeve portion.

[0018] In one embodiment, the filling head structure further includes an air suction assembly for suctioning the inner cavity of the container before filling; the air suction assembly includes an air suction pipe and an air suction channel, the air suction pipe being installed in the first tube body; the air suction channel includes a first air suction sub-channel and a second air suction sub-channel that are connected to each other, the first air suction sub-channel being disposed in the first tube body, and the second air suction sub-channel being disposed through the connecting post.

[0019] To achieve the above objectives, this utility model proposes a filling device, which includes a filling head structure for shampoo as described in any of the above claims.

[0020] The technical solution of this utility model designs the filling head as a first tube and a second tube that can be slidably connected. During the filling operation, an external driving device first moves the entire filling head structure towards the container to be filled, so that the second tube is inserted into the container along the container opening, and the filling port is located in the inner cavity of the container. As the driving device continues to drive, the first circumferentially protruding edge located on the outer side of the second tube abuts against the container opening, thus restricting the second tube from moving, while the first tube continues to move, causing the second tube to slide relative to the first tube from a first position to a second position. Since the sealing component is fixedly connected to the first tube, when the second tube is in the second position, the sealing component releases the seal on the filling port, thereby realizing the filling operation. After the filling operation is completed, the gas injection component injects gas into the infusion channel towards the filling port, and uses the airflow driving force to spray the shampoo remaining in the infusion channel out of the filling port, thereby minimizing the amount of shampoo residue inside the filling head structure and ensuring the quality of the final shampoo product.

[0032] In the shampoo production process, a filling device is used to fill shampoo into containers such as plastic bottles. After filling, a small amount of shampoo remains inside the filling head structure. During the waiting period on the production line, the shampoo remaining inside the filling head structure is prone to denaturation, which causes it to mix with the undenatured shampoo during subsequent filling, thus affecting the quality of the final shampoo product.

[0033] To solve the above-mentioned technical problems, this utility model proposes a filling head structure for shampoo.

[0034] Please see Figure 1-4 In one embodiment of the present invention, the filling head structure includes a first tube 100 and a second tube 200 that are slidably connected; a filling port 201 is provided at one end of the second tube 200 away from the first tube 100; the second tube 200 can be inserted into the container (not shown in the figure) along the container opening to be filled, so that the filling port 201 is located in the inner cavity of the container; an infusion channel 300 is provided inside the first tube 100 and the second tube 200, and the infusion channel 300 is interconnected with the filling port 201;

[0035] A sealing assembly 400 is disposed in the infusion channel 300 and is fixedly connected to the first tube body 100. A first protruding edge 202 is provided circumferentially on the outer side of the second tube body 200. The first protruding edge 202 abuts against the container opening to drive the second tube body 200 to slide relative to the first tube body 100 from a first position to a second position. When the second tube body 200 is in the first position, as shown in the attached diagram... Figure 1 As shown, the sealing assembly 400 seals the filling port 201; when the second tube 200 is in the second position, as shown in the attached diagram... Figure 2 As shown, the sealing component 400 releases the seal on the filling port 201;

[0036] Gas injection assembly 500 is used to inject gas into the infusion channel 300 towards the filling port 201.

[0037] The technical solution of this utility model designs the filling head as a first tube 100 and a second tube 200 that can be slidably connected. During the filling operation, an external driving device (not shown in the figure) is first used to move the entire filling head structure towards the container to be filled, so that the second tube 200 is inserted into the container along the container opening, so that the filling port 201 is located in the inner cavity of the container. As the driving device continues to drive, the first protruding edge 202 located on the outer circumferential side of the second tube 200 abuts against the container opening, so that the second tube 200 is restricted from moving, while the first tube 100 continues to move, so that the second tube 200 slides relative to the first tube 100 from the first position to the second position. Since the sealing component 400 is fixedly connected to the first tube 100, when the second tube 200 is in the second position, the sealing component 400 releases the seal on the filling port 201, thereby realizing the filling operation. After the filling operation is completed, the gas injection component 500 injects gas into the infusion channel 300 towards the filling port 201. The airflow drives the shampoo remaining in the infusion channel 300 to be sprayed out of the filling port 201, thereby minimizing the amount of shampoo residue inside the filling head structure and ensuring the quality of the final shampoo product.

[0038] Specifically, an injection pipe 101 is installed at the end of the first tube 100 away from the second tube 200, and the injection pipe 101 is connected to the infusion channel 300. With this configuration, the filling device injects shampoo from the storage tank into the container through the filling head structure via the injection pipe 101, thereby completing the filling of the shampoo.

[0039] Specifically, the air injection assembly 500 includes an air injection pipe 501, which is installed at the end of the first tube 100 away from the second tube 200. The air injection pipe 501 is connected to the infusion channel 300. This configuration allows the air injection pipe 501 to be connected to an external air pump, enabling the gas generated by the air pump to be injected into the infusion channel 300 via the air injection pipe 501. This, in turn, causes any remaining shampoo in the infusion channel 300 to be ejected from the filling port 201, ensuring the successful implementation of the technical solution of this application.

[0040] Furthermore, the air injection tube 501 is located above the liquid injection tube 101; this arrangement prevents the shampoo injected from the liquid injection tube 101 from flowing into the air injection tube 501 under its own weight.

[0041] Furthermore, the liquid injection tube 101 and / or the air injection tube 501 are inclined toward the filling port 201. This arrangement, with the inclined liquid injection tube 101 and air injection tube 501 serving as guides, ensures that the injected shampoo and gas can move toward the designated filling port 201.

[0042] There are many specific structures for the aforementioned sealing assembly 400. In this embodiment, the sealing assembly 400 includes a connecting post 401 and a sealing element 402. The connecting post 401 is coaxially arranged with the infusion channel 300. One end of the connecting post 401 is fixedly connected to the first tube 100, and the other end of the connecting post 401 is connected to the sealing element 402, which is used to seal the filling port 201. This arrangement uses the connecting post 401 to fix the sealing element 402 to the first tube 100, allowing the sealing element 402 to move with the first tube 100, thus ensuring the smooth implementation of the technical solution of this application.

[0043] Furthermore, the filling port 201 is located on the side of the second tube 200, and the filling port 201 is inclined downward; the side wall of the middle part of the sealing member 402 is used to fit tightly against the inner wall of the second tube 200; the top of the sealing member 402 has a structure that is narrow at the top and wide at the bottom to form a guide slope 403; when the second tube 200 is in the second position, the guide slope 403 of the sealing member 402 and the inclined surface of the filling port 201 are on the same slope. With this configuration, when the second tube 200 is in the first position, the side wall of the middle part of the sealing member 402 is tightly fitted with the inner wall of the second tube 200, which can prevent the shampoo from flowing out of the gap between the sealing member 402 and the second tube 200 and from flowing out of the filling port 201, thereby achieving the purpose of sealing the filling port 201; when the second tube 200 is in the second position, since the guide slope 403 of the sealing member 402 and the inclined surface of the filling port 201 are on the same slope, the shampoo is guided by its slope, so that the shampoo can flow out more smoothly from the filling port 201.

[0044] Furthermore, a second protruding edge 203 is provided on the outer side of the second tube 200 and below the filling port 201. The second protruding edge 203 can be inserted into the container along with the second tube 200. The second protruding edge 203 has a triangular structure, with its inclined surface on the same inclined surface as the filling port 201, and the free end angle of the second protruding edge 203 is set at an acute angle. With this configuration, the shampoo flowing out of the filling port 201 continues to flow into the inner cavity of the container along the inclined surface of the second protruding edge 203. At the same time, because the free end angle of the second protruding edge 203 is set at an acute angle, when the shampoo drips from the free end angle of the second protruding edge 203, the shampoo is difficult to adhere to the bottom side of the second protruding edge 203. It can only drip down to the bottom of the inner cavity of the container under the action of gravity, thereby avoiding shampoo residue on the second protruding edge 203. The structure is simple and highly practical.

[0045] As a preferred embodiment of the above embodiments, refer to Figures 1 to 2The first tube 100 has a cylindrical insertion portion 102, and the second tube 200 has a cylindrical sleeve portion 204. The sleeve portion 204 is slidably sleeved on the insertion portion 102, and a seal is formed between the inner side wall of the sleeve portion 204 and the outer side wall of the insertion portion 102. The filling head structure also includes a spring member 600, which is sleeved on the outside of the sleeve portion 204. The two ends of the spring member 600 abut against the protrusions of the first tube 100 and the second tube 200, respectively. The protrusion of the second tube 200 can be the first protrusion 202 mentioned above. This configuration ensures that the second tube 200 can be smoothly slidably connected to the first tube 100 through the sliding fit between the sleeve part 204 and the insertion part 102. At the same time, a spring member 600 is provided to ensure that when the first protrusion 202 of the second tube 200 is released from contact with the container opening, the elastic force of the spring member 600 can reset the second tube 200, that is, the second tube 200 slides back to the first position. At this time, the sealing component 400 seals the filling port 201, which can prevent the shampoo in the infusion channel 300 from continuing to drip from the filling port 201.

[0046] Furthermore, the insertion part 102 is provided with a limiting groove 1021, the groove direction of which is set in the same direction as the sliding path of the second tube 200 relative to the first tube 100; the sleeve part 204 is provided with a limiting block 2041, which is slidably connected in the limiting groove 1021; with this configuration, the limiting effect between the limiting groove 1021 and the limiting block 2041 ensures that the first tube 100 and the second tube 200 will not separate from each other due to excessive sliding, resulting in a simple structure and strong practicality.

[0047] Furthermore, a sealing layer 2022 is provided on the side of the plug portion 102 that contacts the socket portion 204. This arrangement improves the sealing degree at the connection between the plug portion 102 and the socket portion 204 through the sealing layer 2022, further preventing shampoo from overflowing from the connection between the plug portion 102 and the socket portion 204.

[0048] As a preferred embodiment of the above embodiment, the filling head structure further includes an air suction component 700, which is used to suction air from the inner cavity of the container before filling. With this configuration, considering that when the first protruding edge 202 along the circumference of the second tube 200 abuts against the container opening, a closed structure is formed in the inner cavity of the container, if shampoo is directly filled into the inner cavity at this time, the air inside the container cannot be expelled, thus creating resistance to shampoo filling and preventing the shampoo from fully filling the container. For the above reasons, this embodiment includes an air suction component 700 to suction air from the inner cavity of the container before the filling operation, facilitating subsequent shampoo filling.

[0049] There are many specific structures for the suction assembly 700. In this embodiment, the suction assembly 700 includes a suction pipe 701 and a suction channel 702. The suction pipe 701 is installed in the first tube body 100. The suction channel 702 includes a first suction sub-channel 7021 and a second suction sub-channel 7022 that are connected to each other. The first suction sub-channel 7021 is disposed in the first tube body 100, and the second suction sub-channel 7022 is disposed through the connecting post 401. With this configuration, the suction pipe 701 is connected to an external air pump. Under the driving action of the air pump, the gas in the container cavity is discharged sequentially through the second suction sub-channel 7022, the first suction sub-channel 7021, and the suction pipe 701, thereby creating a vacuum state in the container cavity to facilitate subsequent shampoo filling. The above embodiment has a simple structure and strong practicality. Understandably, sealing rings (not shown in the attached drawings) should be provided at the connection points between the suction pipe 701 and the first suction sub-channel 7021, and between the first suction sub-channel 7021 and the second suction sub-channel 7022, to ensure the sealing of the connection points.

[0050] This utility model also discloses a filling device, including a filling head structure for shampoo according to any of the above embodiments. For the specific structure of the filling head for shampoo, please refer to the above embodiments. Since this filling device adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be elaborated further here.

[0051] It should be noted that the filling head structure for shampoo and other contents of the filling device disclosed in this utility model are prior art and will not be described in detail here.

[0052] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. Any application of this utility model directly or indirectly in other related technical fields is included within the patent protection scope of this utility model.
