[0029] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0030] Example:

[0031] See also Figure 1-Figure 3 A drip-proof filling head includes a tube body 1, a cover plate 2, a drive ring 3 and a support rod 4. The tube body 1 is a cylindrical structure, one end of the tube body 1 is an outlet, and the end close to the outlet of the tube body 1 has a control area 5 inside, the control area 5 is a polygonal columnar space, and the control area 5 in this embodiment is a hexagonal columnar space, and the length direction of the control area 5 is consistent with the axial direction of the tube body 1.

[0032] A plurality of cover plates 2 are arranged in the control area 5. The cover plates 2 are triangular structures. One side of the cover plates 2 is rotatably connected to the cylinder of the control area 5, and the rotation axis of the cover plates 2 is perpendicular to the axis of the tube body 1. All the cover plates 2 are connected to all the cylinders of the control area 5 in a one-to-one correspondence. When all the cover plates 2 are on a horizontal plane, they can together form a plate-like structure and cut off the interior of the tube body 1.

[0033] A driving ring 3 is arranged in the tube body 1 . The driving ring 3 is located below the cover plate 2 and contacts the bottom surface of the cover plate 2 . The driving ring 3 is a circular ring structure.

[0034] At least three support rods 4 are arranged on the driving ring 3 . The support rods 4 are L-shaped structures, and one end of the support rods 4 is connected to the driving ring 3 along the vertical direction.

[0035] A plurality of slide grooves 6 are provided on the tube body 1, the length direction of the slide grooves 6 is consistent with the axial direction of the tube body 1, and the slide grooves 6 penetrate the side wall of the tube body 1. The number of the slide grooves 6 is the same as the number of the support rods 4, and the end of the support rod 4 away from the driving ring 3 passes through the slide groove 6.

[0036] The working principle of this embodiment is that a control area 5 is set inside the outlet end of the tube body 1 of the filling head, and multiple cover plates 2 are rotatably set in the control area 5, and the cover plates 2 are driven to rotate in the control area 5 by the driving ring 3, and the driving ring 3 is prompted to move up and down in the control area 5 through the support rod 4.

[0037] When the filling head is separated from the container, the cover plate 2 and the drive ring 3 automatically fall down under the action of gravity, so that all the cover plates 2 can automatically be in a horizontal state and form a plate-like structure to cut off the inside of the tube body 1, thereby preventing the product in the filling head from dripping from the mouth of the tube body 1.

[0038] During the process of inserting the tube body 1 into the container, the mouth of the container contacts the bottom surface of one end of the support rod 4 passing through the slide groove 6, and as the tube body 1 moves into the container, the mouth of the container presses under the support rod 4 and causes the support rod 4 to slide in the slide groove 6, so that the driving ring 3 drives the cover plate 2 to rotate, thereby opening all the cover plates 2 and forming a complete channel inside the tube body 1.

[0039] In one specific embodiment:

[0040] The cover plate 2 is an isosceles triangle structure. One side of the bottom edge of the cover plate 2 is rotatably connected to the cylindrical surface of the control area 5, and the cover plate 2 is rotatably connected to the lower end of the control area 5. At the same time, the coverage of the control area 5 is greater than the height line length of the cover plate 2.

[0041] In this embodiment, all the cover plates 2 are triangular in shape, so that when all the cover plates 2 form a plate-like structure, the sides of two adjacent cover plates 2 can fit together.

[0042] Preferably, a step 7 is provided on each side of the two waistlines of the cover plate 2, wherein one step 7 is located on the top surface of the cover plate 2, and the other step 7 is located on the bottom surface of the cover plate 2, and the steps 7 of two adjacent cover plates 2 can be interlocked. By providing the steps 7 on both sides of the cover plate 2, the contact surface of the two cover plates 2 can be increased, thereby improving the airtightness.

[0043] In addition, two ends of a side surface where the bottom edge of the cover plate 2 is located are respectively provided with a chamfer, and by providing the chamfer, interference between two adjacent cover plates 2 can be avoided.

[0044] In another specific embodiment:

[0045] A sealing pressure ring 8 is slidably provided in the control area 5 . The sealing pressure ring 8 is a polygonal structure. In this embodiment, the sealing pressure ring 8 is a hexagonal ring structure so as to match the control area 5 .

[0046] The outer side surface of the sealing pressure ring 8 is in sliding contact with the inner side surface of the control area 5, the bottom surface of the sealing pressure ring 8 is in contact with the top surface of the cover plate 2, and the inner side edge of the bottom surface of the sealing pressure ring 8 has an arc-shaped chamfer.

[0047] In this embodiment, by providing a sealing pressure ring 8 , it is possible to prevent the product in the tube body 1 from leaking out from the chamfers at both ends of the bottom edge of the cover plate 2 .

[0048] In another specific embodiment:

[0049] The inner side of the top of the sealing pressure ring 8 is chamfered, and the top of the control area 5 has an annular embedded area, which is also a hexagonal annular structure. The top of the sealing pressure ring 8 can be placed in the embedded area.

[0050] When the sealing pressure ring 8 is at the top end in the control zone 5 , the chamfers and the embedded area at the top of the control zone 5 can prevent the product from penetrating into the contact surface between the sealing pressure ring 8 and the control zone 5 .

[0051] In another specific embodiment:

[0052] A rubber ring is provided on the bottom surface of the sealing ring, and the rubber ring is provided to improve the sealing performance of the cover plate 2 after it forms a plate-like structure.

[0053] In another specific embodiment:

[0054] A sealing plate is provided at the corner of the support rod 4 , and the sealing plate can cover the chute 6 . By providing the sealing plate, the product is prevented from leaking out of the chute 6 .

[0055] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
