Accessories that can be designed to meet the requirements of automatic assembly also emerge. In response to this demand, it has become a trend to design a bottle stopper piercer with this structure.

[0003] A Chinese patent (authorization announcement number: CN217366763U) proposes a bottle stopper puncture device. The purpose is to solve the problem in the prior art that water in the infusion bottle will wet the air filter membrane after entering the air inlet channel, slowing down the air intake and preventing liquid from flowing out of the liquid outlet pipe. The main scheme includes a puncture body, on which a liquid outlet channel and an air inlet channel are provided, an air filter membrane is provided at the air inlet end of the air inlet channel, and a gravity one-way valve structure is also provided between the air inlet channel and the air filter membrane, the gravity one-way valve structure includes an air filter seat, the air filter seat is provided with a through hole with an opening plane facing upward horizontally, the through hole is covered with a diaphragm, and the diaphragm covers the through hole under the action of gravity.

[0004] The original transparent plastic needle bottle stopper puncture device needs to be assembled into a dripper for infusion. The connection between the puncture device and the drip bucket must be completed through an inner ring placed inside. In this way, it is difficult to realize the automation of the production of such a dripper, and an extra inner ring mold must be opened and the inner ring product must be produced. For this reason, we propose a bottle stopper puncture device with a drip bucket mating surface. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution: a bottle stopper puncture device with a matching surface of a drip bucket 1, comprising a drip bucket 1, a puncture mechanism 2 fixed on the bottle stopper is arranged at the upper end of the drip bucket 1, the puncture mechanism 2 comprises a puncture head 201, and the infusion is made more convenient by inserting the puncture head 201 into the bottle stopper of the liquid bottle, a vent hole 202 is arranged inside the puncture head 201, a one-way ventilation protection mechanism 3 is arranged at the air inlet end of the vent hole 202, and the one-way ventilation protection mechanism 3 arranged at the vent hole 202 prevents the liquid in the liquid bottle from being discharged through the vent hole 202.

[0024] A connecting ring 206 is fixedly installed at the lower end of the inner wall of the drip bucket 1. The connecting ring 206 provided on the drip bucket 1 makes it more convenient to connect and install the infusion tube after the puncture head 201 is inserted and installed. A water inlet hole 205 is provided inside the puncture head 201 away from the vent 202. The water inlet hole 205 provided on the puncture head 201 enables the liquid material in the liquid bottle to be discharged through the water inlet hole 205 after the puncture head 201 is inserted into the liquid bottle, and the end of the puncture head 201 close to the drip bucket 1 protrudes from the inner wall of the drip bucket 1, thereby reducing the height of the dripping liquid.

[0025] An air inlet 203 is provided at the lower end of the vent hole 202 , and an air inlet filter 204 is fixedly installed at the air inlet end of the air inlet 203 . The air inlet filter 204 provided at the air inlet 203 filters the incoming air, thereby preventing dust or other debris in the air from entering through the air inlet 203 .

[0026] A plurality of barb rings 207 are fixedly mounted on the upper end of the outer wall of the puncture head 201. The barb rings 207 arranged on the puncture head 201 allow the puncture head 201 to be inserted into the bottle stopper of the liquid bottle, so as to prevent the puncture head 201 from falling off. A rubber telescopic tube 209 is fixedly mounted on the lower end of the outer wall of the puncture head 201. The rubber telescopic tube 209 is set to an elastic telescopic material, so that after the rubber telescopic tube 209 contracts, a certain spring thrust is provided. A retaining ring 208 is fixedly mounted on the upper end of the rubber telescopic tube 209, and the retaining ring 208 is slidably mounted on the outer wall of the puncture head 201. When the puncture head 201 is inserted into the bottle stopper, the retaining ring 208 squeezes the rubber telescopic tube 209. After the puncture head 201 is fully inserted, the rubber telescopic tube 209 pushes the retaining ring 208 to rise, so that the barb rings 207 cooperate with the retaining ring 208, and the puncture head 201 is fixed at the insertion position of the bottle stopper.

[0027] The protection mechanism 3 includes a mounting tube 301, and the mounting tube is fixedly installed inside the air inlet 203 near the vent 202. A sealing plate 303 is symmetrically rotated at one end of the mounting tube 301 away from the vent 202, and the sealing plate 303 is set to be a semicircular plate that matches the inner wall diameter of the mounting tube 301, and the sealing plate 303 is set to be a foam hollow material. When liquid enters the mounting tube 301 through the vent 202, the sealing plate 303 rotates to block one end of the mounting tube 301, thereby preventing the liquid from dripping onto the air intake filter 204 through the vent 202, causing the air intake filter 204 to become wet and the air permeability is reduced.

[0028] A plurality of blocks 302 are symmetrically installed on the inner wall of the mounting tube 301, and the blocks 302 are arranged in an arc shape to fit the inner wall of the mounting tube 301. The blocks 302 arranged on the mounting tube 301 block the sealing plate 303 from rotating, thereby preventing the sealing plate 303 from rotating too much, resulting in the sealing plate 303 not rotating back to its original position after liquid enters through the vent hole 202.

[0029] Working principle: when the puncture device is needed, the puncture head 201 is inserted through the stopper of the liquid bottle, the barbed ring 207 arranged on the puncture device is inserted into the stopper, and the retaining ring 208 squeezes the rubber telescopic tube 209. After the puncture head 201 is fully inserted, the rubber telescopic tube 209 pushes the retaining ring 208 to rise, so that the barbed ring 207 cooperates with the retaining ring 208 to fix the puncture head 201 at the insertion position of the stopper, thereby preventing the puncture device from falling off. The structure is simple, the production and manufacturing are convenient, the cost is low, and the assembly is convenient.
