Description

Technical Field

[0001] This utility model relates to the field of filling technology, and in particular to a drip-proof detergent filling head. Background Technology

[0002] Lotions are liquid preparations made from the extraction or mixing of medicinal herbs. They are mainly used for cleaning and treating unbroken skin or mucous membranes (such as the mouth and vagina). During the packaging stage, lotions require the use of a liquid filling machine for filling and packaging. When the bottle is full of liquid, the inlet pipe stops feeding liquid into the filling head, but the remaining liquid in the filling head will continue to drip into the bottle, causing the liquid in the bottle to overflow, resulting in contamination of the bottle and waste of liquid.

[0003] In the prior art, CN206705659U discloses an anti-drip filling head, including a valve body and a hollow tubular needle. The valve body contains a silicone bead, a spring, and a guide tube. One end of the valve body extends outwards to form an inlet tube, and the other end communicates with the needle tube. The silicone bead is located within the valve body and close to the inlet tube. One end of the guide tube abuts against the silicone bead, and the other end is fitted with a spring. The other end of the spring is fixedly connected to the inner wall of the valve body and close to the needle tube. Its advantage is that when the inlet tube stops supplying liquid, it prevents excess liquid in the inlet tube from entering the valve body, thus preventing liquid dripping and reducing waste.

[0004] However, the anti-drip structure of the aforementioned filling head is quite complex, which increases both the production cost and maintenance cost of the filling head.

[0005] To address this issue, a drip-proof detergent filling head is proposed, which possesses the advantage of being drip-proof and thus solves the problems mentioned in the background technology. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a leak-proof detergent filling head.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a drip-proof detergent filling head, comprising a filling head body, wherein a hinge block is fixed on each of the left and right sides of the lower part of the filling head body, and a left conical shell is rotatably mounted on the hinge block on the left side of the filling head body, and a right conical shell is rotatably mounted on the hinge block on the right side of the filling head body. A spoon-shaped receiving shell is integrally formed on the conical surface of the left conical shell, and a guide plate is obliquely welded to the inner wall of the right conical shell corresponding to the spoon-shaped receiving shell, with one end of the guide plate located below the filling port of the filling head body. A first fixing ear is welded to the surface of the left conical shell, and a second fixing ear is welded to the surface of the right conical shell. A quick-release screw is inserted between the first fixing ear and the second fixing ear.

[0008] As a further description of the above technical solution: the left conical shell and the right conical shell are semi-conical shells of the same size, and the left conical shell and the right conical shell fit together perfectly.

[0009] As a further description of the above technical solution: two hinge ears are welded and installed at the upper ends of the left conical shell and the right conical shell, and through holes are opened on the surface of the two hinge ears. Columnar protrusions connected to the through holes of the hinge ears are respectively provided on both sides of the hinge block.

[0010] As a further description of the above technical solution: one end of the guide plate extends to the inner side of the left conical shell, and an arc groove is provided inside the guide plate.

[0011] As a further description of the above technical solution: the cross-section of the spoon-shaped receiving shell is an inverted spoon-shaped structure, and the inner space of the spoon-shaped receiving shell forms a drip receiving cavity.

[0012] As a further description of the above technical solution: both the first fixing ear and the second fixing ear have circular holes on their surfaces, and the first fixing ear and the second fixing ear fit together with each other.

[0013] This utility model has the following beneficial effects:

[0014] In this invention, a left conical shell and a right conical shell are hinged at the filling port of the filling head body, and screws are used to lock the left and right conical shells together. When the detergent is filled through the filling head body, the dripping detergent residue flows into the spoon-shaped receiving shell of the left conical shell through the guide plate of the right conical shell, avoiding direct leakage of detergent residue and contamination of the packaging bottle. In the next detergent filling stage, the impact force of filling with sufficient detergent can carry out the residue in the spoon-shaped receiving shell. Combined with the first fixing ear, the second fixing ear and the quick-release screw installed between them, it not only meets the requirements of preventing dripping, but also has the advantages of simple structure and easy maintenance, thereby minimizing production and maintenance costs.

The filling head body 1 is equipped with a second fixing ear 9, and a quick-release screw is inserted between the first fixing ear 8 and the second fixing ear 9. This structure prevents the residual detergent from dripping out and contaminating the packaging bottle. In the next detergent filling stage, the impact force of filling a sufficient amount of detergent can carry out the residual liquid in the spoon-shaped receiving shell 4. Combined with the first fixing ear 8 and the second fixing ear 9 and the quick-release screw installed between them, it not only meets the requirements of preventing dripping, but also has the advantages of simple structure and easy maintenance, thereby minimizing the production and maintenance costs. The principle of the filling head body 1 is a known existing technology, and there are mature products available. Therefore, its principle will not be explained further.

[0024] In one embodiment, the left conical shell 2 and the right conical shell 3 are semi-conical shells of the same size, and the left conical shell 2 and the right conical shell 3 fit together perfectly. With this structure, it is easy to seal and guide the filled detergent, so that it can be accurately injected into the packaging bottle.

[0025] In one embodiment, two hinge ears 6 are welded to the upper ends of both the left conical shell 2 and the right conical shell 3, and through holes are opened on the surface of both hinge ears 6. Columnar protrusions connected to the through holes of the hinge ears 6 are respectively provided on both sides of the hinge block 5. This structure facilitates the rotation and installation of the left conical shell 2 and the right conical shell 3, and makes subsequent cleaning convenient.

[0026] In one embodiment, one end of the guide plate 7 extends to the inner side of the left conical shell 2, and the guide plate 7 is provided with an arc groove 10. With this structure, it is easy to receive the dripping detergent and guide it into the spoon-shaped receiving shell 4.

[0027] In one embodiment, the cross-section of the spoon-shaped receiving shell 4 is an inverted spoon shape, and the inner space of the spoon-shaped receiving shell 4 forms a drip receiving cavity. With this structure, it is easy to contain dripping detergent.

[0028] In one embodiment, the surfaces of the first fixing ear 8 and the second fixing ear 9 are both provided with circular holes, and the first fixing ear 8 and the second fixing ear 9 fit together. With this structure, it is easy to lock the left conical shell 2 and the right conical shell 3 after they are joined together.
