[0020] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] Please see Figures 1 to 4 This is a double-layer juicing filter bag, which is the preferred embodiment of the present invention, comprising an outer bag 10 and an inner filter bag 20, wherein: The outer bag 10 is formed by welding the edges of the double-layer film. After welding the two sides of the outer bag 10, a cavity 30 is formed inside it. The upper side of the outer bag 10 is not welded, thus forming a dispensing port 40 that connects to the cavity 30. The lower side of the outer bag 10 is welded, and it protrudes outward near the bottom edge (left side in this embodiment, but it can also be right side) to form a juice outlet 50. The inner side of the dispensing port 40 is provided with at least two vertically parallel self-sealing strips 60. In this embodiment, there are two strips, so that the opening and sealing of the dispensing port 40 on the upper side of the cavity 30 can be easily controlled by the self-sealing strips 60. The double self-sealing strips 60 further enhance the sealing performance and reduce the probability of the juice filter bag bursting open under pressure.

[0022] In this embodiment, the inner filter bag 20 is made of food-grade non-woven fabric and has an inner storage area 21 for holding the material to be juiced. The pulp to be juiced is placed in the storage area 21 beforehand. After the outer bag 10 is pressed, the inner filter bag 20 and the pulp inside are pressed simultaneously, and the juice is filtered out along the inner filter bag 20.

[0023] In addition, the cavity 30 has a positioning area 31 formed by several welded positioning strips 70 on its inner side. The positioning area 31 is used to hold the inner filter bag 20 in a fixed position within the cavity 30 and has an opening for inserting the inner filter bag 20.

[0024] In this embodiment, the welding positioning strip 70 is a long, waist-shaped strip, and two welding positioning strips 70 form a group, forming three groups in total. These groups are distributed on three adjacent sides of the same rectangular area. Thus, the three groups of welding positioning strips 70 can enclose and form a rectangular positioning area 31. The side not covered by the welding positioning strip 70 faces the inlet 40, forming an opening for easy insertion of the inner filter bag 20. By opening the double self-sealing strip 60, the inner filter bag 20 can be easily inserted into the positioning area 31. The three groups of welding positioning strips 70 form a barrier, restricting the inner filter bag 20 to a fixed area within the cavity 30. After the self-sealing strip 60 is closed, the subsequent juicing process can be carried out.

[0025] The positioning area 31 formed by the three sets of welding positioning strips 70 is roughly located at the center of the cavity 30.

[0026] In addition, the welding positioning strip 70 and the inner edge of the cavity 30 are spaced to form a transition chamber 32 outside the positioning area 31, and there is a gap between adjacent welding positioning strips 70 to form a juice outlet channel 33 connecting the positioning area and the transition chamber 32. Specifically, in this embodiment, the positioning area 31 is defined as a rectangle by three sets of welded positioning strips 70. The positioning area 31 can also be defined as a rounded rectangle, a circle, or a trapezoid, which is not limited here.

[0027] Specifically, the distance d1 between the welding positioning strip 70 and the inner edge of the cavity 30 is 1cm, and the distance d2 between adjacent welding positioning strips 70 is 2cm, thereby forming the aforementioned transition chamber 32 and juice outlet channel 33, which facilitates the juicing operation.

[0028] In addition, a one-way valve 80 for discharging juice is provided inside the juice outlet 50. In this embodiment, the one-way valve 80 is a disposable or resettable diaphragm one-way valve 80, and a filter screen 81 for filtering residue is provided on its inlet or outlet side.

[0029] The membrane check valve 80 mentioned above is a common type of check valve 80 made of membrane in the field. It has a wide range of applications, such as decorative balloons and letter balloons. Its principle and structure will not be described in detail here.

[0030] In addition, during the preparation of the outer bag 10, the filter screen 81 is simultaneously welded and fixed along with the welding position of its edge.

[0031] Preferably, the outer bag 10 has a plurality of fixing holes 11 for hanging at the opening of the inlet 40. In this embodiment, there are two fixing holes 11, which are symmetrically distributed about both sides of the outer bag 10.

[0032] Preferably, the outer surface of the outer bag 10 is provided with a laser anti-counterfeiting label 12. The laser anti-counterfeiting label 12 can be used to record the production date of the pulp in the filter bag of this batch, which is convenient to link with the corresponding pressing equipment and manage the expired pulp batch.

[0033] Preferably, the outer bag 10 is a food-grade nano-breathable and light-blocking composite film with micropores, which can be reused while taking into account breathability and anti-oxidation. The material of this film is also common in the field and will not be described in detail here.

[0034] The working process and beneficial effects of this utility model are as follows: First, open the double self-sealing strip 60 to open the inlet 40 of the outer bag 10. Then, place the inner filter bag 20 containing fruit pulp into the inlet 40, allowing it to slide in along the opening of the positioning area 31 and finally stop within the boundary range formed by the welded positioning strip 70. After removing excess air, reseal the double self-sealing strip 60 to seal the outer bag 10. Finally, with the help of external extrusion equipment, extrude pressure on the front and back sides of the outer bag 10 at the corresponding positions of the positioning area 31. This causes the fruit pulp in the inner filter bag 20 to be crushed and juice to flow out. The juice continues to flow into the transition chamber 32 for buffering along the juice outlet 33 between the welded positioning strips 70. After converging in the transition chamber 32, it continues downward, opening the one-way valve 80 and flowing out along the juice outlet 50, completing the entire juicing process.

[0035] This invention uses a welding positioning strip 70 to fix the position of the inner bag and a transition chamber 32 to buffer the impact of juice, providing double protection to prevent the inner bag from breaking. At the same time, the inner filter bag 20 is replaceable and the outer bag 10 can be reused, thereby significantly reducing the cost of use.

[0036] In addition, the double self-sealing strip 60 enhances the seal, and the staggered squeezing position ensures that no leakage occurs during juicing, further improving the success rate of juicing; In addition, filter 81 is used to further intercept fruit pulp, preventing it from flowing out and mixing into the juice, so as not to affect the taste of the juice. In addition, the laser anti-counterfeiting label 12 can be used to record the production date of the pulp in the filter bag of this batch, which can be conveniently linked with the corresponding pressing equipment to manage the expired pulp batches.

[0037] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
