Technical Field
[0001] This invention relates to a food preservation bag for household refrigerators that uses incense to consume oxygen and replenish carbon dioxide, belonging to the field of food preservation science and technology. Background Technology
[0002] With the improvement of people's living standards and the increase in family income, fresh fruits and other foods have gradually become an important part of people's daily diet. However, all foods have a certain shelf life, meaning their storage time is not very long. Fruits, in particular, have a distinct seasonality. Once ripe, the cells within the fruit quickly enter a programmed death process, causing them to rot and release water. This provides suitable conditions for the growth and reproduction of microorganisms, further accelerating the decay of the fruit. Therefore, a large amount of fruit is lost each year due to spoilage. In households, different people have different tastes, and when encountering a favorite fruit, people often buy more. Any uneaten fruit is stored in the refrigerator. However, although the low temperature in the refrigerator greatly slows down the programmed cell death process, even slightly spoiled cells can provide a suitable growth substrate for microorganisms, causing the fruit to rot faster and quickly lose its edible value. Therefore, how to conveniently store fresh fruits and other foods in the refrigerator for a longer period without causing spoilage has become a major problem that urgently needs to be solved. CN202210196881.3 provides a fruit preservation container with a biomimetic eggshell structure and an internal sterilization cloth cover; CN202510134583.5 provides the application of natural inducers in fruit preservation; CN202510121403.X provides polyethanol-coated preservation paper and its preparation method; CN202510060328.0 provides a highly efficient antibacterial and fully degradable preservation film and its preparation method; CN202411980705.4 provides an apple storage soaking solution and apple storage method; CN202411881465.2 provides a method for extending the shelf life of fruit using a modified atmosphere packaging box; CN202411852150.5 provides a low-temperature storage and preservation method for lychees; CN202411850996.5 provides a lychee preservation liquid and its application; CN202411...

In the field of fruit preservation, CN202411570756.X provides a fermentation method for Lactobacillus mucilaginosus and its application; CN202411523506.0 provides a green preservative and its preparation method and application; and CN202411478552.3 provides a biodegradable preservation film for fruit preservation and its preparation method. All of these patents can, to a certain extent, prevent fresh fruits and other foods from rotting and spoiling when stored in the refrigerator's cold storage compartment for a longer period of time. However, they are mostly disposable. After use, they need to be recoated, and the equipment cannot be recycled, making them extremely inconvenient to use. To overcome the challenge of conveniently storing fresh fruits and other foods in the refrigerator's crisper drawer for extended periods without causing spoilage, this invention provides a household refrigerator food preservation bag that uses incense to consume oxygen and replenish carbon dioxide. This bag employs an electric heating process to rapidly consume the oxygen within the bag by burning incense granules, producing carbon dioxide gas. Furthermore, the fresh fruits and other foods are wrapped in absorbent paper or wrapping paper with strong water-absorbing capabilities. The moisture and gases such as ethylene produced during storage are absorbed or decomposed. In the sealed space, water droplets do not accumulate on the surface of the fresh fruits and other foods, preventing the growth and reproduction of microorganisms that cause spoilage. Therefore, fresh fruits and other foods can be stored in the refrigerator's crisper drawer for a longer period and retain their excellent quality after being removed. The invention of this household refrigerator food preservation bag using incense to consume oxygen and replenish carbon dioxide is therefore necessary. Summary of the Invention

[0019] Example 1:
[0020] As shown in the figure, the present invention relates to a food preservation bag for home refrigerators that uses incense to consume oxygen and supplement carbon dioxide. It comprises a preservation bag body 1, an incense burner 2, an incense lighter 3, a self-sealing strip 4, a preservation bag opening 5, a preservation bag pleated edge 6, an incense storage compartment 7, an air outlet compartment 8, an air inlet 9, an air outlet 10, a combustion chamber 11, a power cord 12, incense particles 13, incense particle body 14, an incense particle central hole 15, an incense lighter head 16, a support ball 17, a resistance wire 18, an incense stick 19, a support ball groove 20, a positive power cord 21, a sheath cavity 22, a negative power cord 23, a sheath 24, an incense lighter control button 25, a release spring 26, a pressure film 27, a retaining shaft head 28, a connecting retaining film groove 29, a retaining rod cylinder 30, an anti-detachment protrusion 31, a positive protrusion 32, a positive electrode plate 33, a button battery 34, a pressing shaft 35, and a preservation bag bottom 36. The food storage bag body 1 is a self-sealing plastic bag for holding food, incense burner 2, and incense lighter 3. The plastic film used is made of polyethylene, polypropylene, polyvinyl chloride, or polyvinylidene chloride, with a thickness of 6-20 mils. The length of the food storage bag body 1 is 20-40 cm and the width is 20-30 cm. During production, the cylindrical plastic film is cut into segments 20-40 cm long. After flattening, the width of the plastic film tube is 20-30 cm. The flattened plastic film tube forms food storage bag pleats 6 on both sides. Then, one end of the plastic film tube is heat-sealed together to form a food storage bag. The bottom of the plastic film tube is 36; the other end of the plastic film tube is open, forming the opening 5 of the plastic bag. A self-sealing strip 4 is set inside the opening 5, 1-2 cm from the edge of the opening 5. The self-sealing strip 4 is made of plastic and consists of a cylindrical strip and a groove that can fit into the cylindrical strip. The cylindrical strip and the groove are respectively set on the inner surface of the two sides of the plastic bag body 1. When the opening 5 of the plastic bag is torn open, the self-sealing strip 4 can be pulled open to complete the filling of the plastic bag body 1. After the self-sealing strip 4 is pressed closed, it can seal the opening 5 of the plastic bag and preserve food. The preservation bag body 1 forms a sealed environment; both the incense burner 2 and the incense igniter 3 are located inside the preservation bag body 1. The incense burner 2 is not fixed, and the incense igniter 3 is the component that ignites the incense granules 13. The outer end of the incense igniter 3 is called the incense igniter control button 25, and the inner end of the incense igniter 3 is called the incense igniter head 16. The incense igniter control button 25 and the incense igniter head 16 are connected together by a power cord 12. The ceramic rod at the base of the incense igniter head 16 is fixed to the side wall of the combustion chamber 11, thereby fixing the incense igniter head 16 in the combustion chamber 11 of the incense burner 2; the incense igniter control button 25 is pressed... When the shaft 35 is pressed down, the positive electrode protrusion 32 at the lower end of the shaft 35 is lowered and comes into contact with the positive electrode plate 33 on the upper surface of the button battery 34, thereby closing the circuit of the entire incense burner 3 consisting of the incense burner control button 25, the power cord 12 and the incense burner head 16. The electrical energy of the button battery 34 is converted into heat energy at the resistance wire 18 and the incense stick 19, thereby igniting the incense particles 13 close to the support ball 17. The burning of the incense particles 13 consumes the oxygen in the combustion chamber 11 and releases the carbon dioxide produced by the combustion, thereby achieving the purpose of burning incense in the food preservation bag to consume oxygen and replenish carbon dioxide.The abutment 35 is made of plastic or rubber and consists of three parts: upper, middle, and lower. The upper part of the abutment 35 is cylindrical, with a diameter of 1-1.5 cm and a height of 2-5 mm, and is located above the release spring 26. The middle part of the abutment 35 is cylindrical, with a diameter of 5-10 mm and a height of 10-15 mm, and passes through the fixing rod tube 30. A locking protrusion 31 is fixed to the lower outer surface of the middle part of the abutment 35 by a screw thread. This prevents the middle part of the abutment 35 from slipping out of the fixing rod tube 30 when the release spring 26 pushes against it. The locking protrusion 31 is made of plastic or rubber and is annular, with an inner diameter of 5-10 mm, an outer diameter of 7-15 mm, and a thickness of 1- The lower surface of the ring is flush with the lower end of the middle part of the push shaft 35. The anti-detachment protrusion 31 is fixedly connected to the push shaft 35 with adhesive. The lower part of the push shaft 35 is conical, with an upper base diameter of 5-10 mm and a height of 3-5 mm. A copper sheet is fixedly connected to the outer surface of the tip of the cone. After the copper sheet is fixed to the outer surface of the tip of the cone, it forms the positive electrode protrusion 32. The edge of the positive electrode protrusion 32 is welded to the positive power line 21 and can move up and down with the movement of the lower part of the push shaft 35. When the push shaft 35 is pressed by external force, the positive electrode protrusion 32 falls and connects with the positive electrode plate 33, the circuit is closed, and the incense burner 3 functions to ignite the incense pellet 13. The positive electrode plate 33 is made of copper and is in the shape of a disc. The thickness is 0.01-0.05 mm, and the diameter is 3-5 mm. It is set on the upper surface of the button battery 34 and connected to the positive terminal of the button battery 34. When the push shaft 35 is released, under the action of the release spring 26, the upper part of the push shaft 35 is ejected, the positive terminal protrusion 32 rises and separates from the positive terminal plate 33, the circuit of the entire incense burner 3 is disconnected, the incense pellet 13 is no longer lit, and the already lit incense pellet 13 will also quickly extinguish as the oxygen is exhausted, while the carbon dioxide produced by the burning incense pellet 13 will quickly dissipate into the entire food preservation bag along the vent 10; the release spring 26 is made of spring steel and is spiral in shape, the inner diameter of the spiral is 5.5-11 mm, which fits perfectly in the push shaft 35. Outside the part, pressing the push shaft 35 can store elastic potential energy for the spring 26. When the hand is released, the elastic potential energy is converted into an upward elastic force, pushing the push shaft 35 upward, thereby disconnecting the circuit of the incense burner 3. The retaining rod cylinder 30 is a cylindrical cylinder set in the center of the retaining shaft head 28. It is cylindrical and is the space for the push shaft 35 to move up and down. Its diameter is 5.1-10.2 mm and its height is 5-10 mm. The button battery 34 is a commercially available button dry cell battery. It is set in the retaining shaft head 28 below the positive electrode 33. The upper surface of the button battery 34 is the positive electrode and is welded to the positive electrode 33. The lower surface of the button battery 34 is the negative electrode and is welded to this end of the negative power line 23.Power cord 12 is a double-stranded copper core power cord connecting the incense burner head 16 and the incense burner control knob 25. The cross-sectional diameter of the copper core is 0.1-0.3 mm. One strand of power cord 12 is the positive power cord 21, which connects to the positive terminal of the button battery 34 through the positive protrusion 32 and the positive plate 33. The other strand is directly connected to the negative terminal of the button battery 34. Each power cord has a sheath made of silicone rubber, which has excellent high-temperature resistance and a thickness of 0.1-0.2 mm. After the two copper core power cords run parallel, another sheath is wrapped around them, called sheath 24. Sheath 24 is made of silicone rubber, which has excellent high-temperature resistance and a thickness of 0.2-0.5 mm. The cavity enclosed by sheath 24 in power cord 12 is called sheath cavity 22. The positive power cord 21 and the negative power cord 23 are connected to the positive power cord 21 and the negative power cord 23. All components are housed within the foreskin cavity 22, except that the incense burner head 16 and the incense burner control button 25, as well as the positive power line 21 and the negative power line 23, are separately connected to their corresponding structural components. The pressure plate 27 is a plate that fixes the incense burner head 16 to the food storage bag body 1. It is made of copper, plastic, or stainless steel and is generally circular. However, a circular protrusion with a diameter of 8-12 mm is welded and fixed near the edge. The center of this circular protrusion coincides with the center of the fixing rod cylinder 30 inside the fixing head 28. The upper surface of the fixing head 28 is flat, and a connecting fixing groove 29 is provided at the circular position on the lower surface of the pressure plate 27. When the circular position on the lower surface of the pressure plate 27 is pressed into the connecting fixing groove 29, the pressure plate 27 can be tightly connected to the bag body 1. The fixed shaft heads 28 are connected together. Therefore, during installation, a round hole with a diameter of 5-10 mm is made inside the self-sealing strip 4 of the fresh bag opening 5 on the bottom wall of the fresh bag body 1. Then, the release spring 26 is sleeved on the middle of the pressing shaft 35, and then the pressure film 27 is sleeved on. Next, the middle part of the pressing shaft 35 is inserted from the outside to the inside along the round hole on the fresh bag body 1. The middle part of the pressing shaft 35 is inserted into the fixing rod cylinder 30. After the middle part of the pressing shaft 35 protrudes from the lower end of the fixing rod cylinder 30, the anti-detachment protrusion 31 is fixed. After the button battery 34, the positive electrode protrusion 32, and the positive electrode plate 33 are connected to the positive power line 21 and the negative power line 23, the entire fixed shaft head 28 is integrated into a whole. At the same time, the pressure film 27 is pressed, so that the ring of the pressure film 27 is pressed into the connecting film groove 29, thereby lighting the incense. The incense burner head 16 is fixed to the food storage bag body 1. The incense burner head 16 is a structure that converts electrical energy into heat energy to ignite the surrounding incense particles 13. It consists of a support ball 17, a resistance wire 18, an incense stick 19, a support ball groove 20, a positive power line 21, and a negative power line 23. The support ball 17 is spherical in shape, made of ceramic, and has a diameter of 5-10 mm. The support ball groove 20 is an annular groove located at the equator of the support ball 17. The cross-section is semi-circular, and the diameter of the semi-circle is 0.1-0.3 mm. It is used to hold the resistance wire 18. The two ends of the resistance wire 18 are connected to the positive power line 21 and the negative power line 23, respectively. The resistance wire 18 is made of tungsten, has a circular cross-section, and a diameter of 0.1-0.2 mm. The resistance wire 18 is a structure that converts electrical energy into heat energy.Four to eight incense sticks 19 are set on the ball support groove 20, with an included angle of 30°-60° between adjacent incense sticks. Each incense stick 19 is made of copper, and once it turns red-hot, it can ignite the incense pellets 13 that are close to it. The incense pellets 13 are spherical, with a diameter of 1-2 mm, and are made of a mixture of mugwort powder, elm bark powder, and cotton thread. The central hole 15 of the incense pellet is a cylindrical hole in the center of the incense pellet 13, with a cross-sectional diameter of 0.1-0.2 mm. Cotton thread is placed inside the hole to aid combustion of the incense pellet body 14. The incense pellet body 14 is the solid part of the incense pellet 13 excluding the central hole 15, and is composed of mugwort powder and elm bark powder. During production, the dried or oven-dried mugwort and elm bark are first pulverized into powder using a pulverizer, and then sieved to remove impurities and larger particles, so that the particle size of the powder is above 200 mesh. Elm bark powder is then added to the powder at a ratio of 5%. Add an appropriate amount of water to the mugwort powder, and mix the mugwort powder and elm bark powder in the correct proportions to form a fragrant paste. Then, use a mold to extrude the fragrant paste into strips with a cross-sectional diameter of 1-2 mm. Place the fragrant paste strips in a long groove with a semi-circular cross-section. Take a cotton thread, stretch it taut, and pull it back and forth along the length of the groove, so that the cotton thread cuts into the center of the fragrant paste strip. Then, place the fragrant paste strip with the cotton thread embedded in the center horizontally on a rolling board and slide it back and forth. The cut formed by the cotton thread is kneaded and closed, and the outer part of the long fragrant paste strip is kneaded into small balls of fragrant powder.13 Because the cotton thread continuously kneads throughout the kneading process... The individual incense granules 13 are then strung together with cotton thread to form an incense granule string. Finally, the formed incense granule string is placed in a well-ventilated and dry place to air dry completely before use. When using, the incense granule string is placed in the combustion chamber 11 around the incense burner head 16. Because the incense stick 19, after being powered on, has a high temperature, far exceeding the ignition point of the mugwort powder, it ignites the incense granules 13 near the incense stick 19. This allows the incense granules 13 to quickly consume the oxygen in the inner cavity of the preservation bag 1 during combustion, releasing the carbon dioxide produced by the combustion of the incense granules 13, thus creating an oxygen-free, high-carbon dioxide environment inside the preservation bag 1. The carbonized environment prevents the growth of aerobic bacteria, extending the shelf life of fruits. Simultaneously, burning mugwort releases terpenoids such as eucalyptol, camphor, thujone, and β-caryophyllene, as well as volatile oil components like borneol, 2,2′-dithiophene, 3,3,6,8-tetramethyl-1-tetrahydronaphthone, and 6-apigen-4-ol. Eucalyptol possesses antibacterial, anti-inflammatory, and antioxidant properties; camphor, with its distinctive aroma and insect-repellent and antibacterial effects, is released during mugwort burning; and terpenoids exhibit certain antibacterial and anti-inflammatory biological activities, making them one of the effective components for mugwort fumigation, disinfection, and insect repellency.The volatile oil components such as borneol, 2,2′-dithiophene, 3,3,6,8-tetramethyl-1-tetrahydronaphthone, and 6-apigen-4-ol are released during combustion, which together constitute the material basis for the pharmacological effects of mugwort smoke. Therefore, the substances released by burning mugwort can have antibacterial and disinfecting properties, which is also the material basis for extending the shelf life of fruits. The incense burner 2 is a structure that ignites the incense granules 13, consuming the oxygen in the air inside the preservation bag 1 and producing carbon dioxide gas that diffuses into the preservation bag 1. It is located inside the power cord 12 inside the preservation bag 1. The incense burner 2 is made of ceramic and is rectangular in shape. The length of the incense burner 2 is 3-5 cm, the width is 2-3 cm, and the thickness is 5-10 mm. The incense burner 2 consists of an incense granule storage chamber 7, an air outlet chamber 8, an air supply port 9, an air outlet port 10, and a combustion chamber 11. The incense granule storage chamber 7 is the space for holding the incense granules 13. It has an inclined bottom and a circular opening on the wall connected to the combustion chamber 11 so that the incense granules 13 can slide down into the combustion chamber by gravity. Inside chamber 11; combustion chamber 11 is the space where, when powered on, incense pellets 13 are burned, consuming oxygen and producing carbon dioxide, and an incense burner head 16 is installed inside; air outlet chamber 8 is a cavity that supplies air from inside the preservation bag 1 into the combustion chamber 11 and exhausts the carbon dioxide gas produced by combustion in the combustion chamber 11. Since the incense burner 2 is made of ceramic, and with the buffer of air outlet chamber 8, the burning of incense pellets 13 will not cause scalding or other effects on the plastic preservation bag 1. Air outlet chamber 8 is connected to combustion chamber 11 through air inlet 9, and the gas in air outlet chamber 8 diffuses into the preservation bag 1 through air outlet 10 on the wall of air outlet chamber 8. Both the air inlet 9 and the air outlet 10 are through holes, allowing gas to pass freely. In the incense burner 2, the incense pellets 13 that have slid from the incense pellet storage chamber 7 into the combustion chamber 11 accumulate around the support ball 17. When the button 35 of the incense burner control button 25 is pressed, the circuit is closed, and the resistance wire 18 in the support ball groove 20 converts electrical energy into heat energy, causing the metal incense stick 19 to heat up and turn red, thus allowing the incense pellets 13 near the support ball 17 to reach their ignition point and burn. The burning of the incense pellets 13 can, on the one hand, burn the incense... The bactericidal substances in granules 13 volatilize, achieving the effect of sterilizing and purifying the air inside the preservation bag 1. On the other hand, the combustion of granules 13 can quickly consume the oxygen in the air inside the preservation bag 1, forming carbon dioxide gas, thereby extending the shelf life of food. At the same time, after the oxygen in the air inside the preservation bag 1 is consumed, the oxygen required for the combustion of granules 13 is used up, and granules 13 will automatically extinguish and will not continue to burn. There is no need to worry about the safety hazards that may be caused by prolonged combustion of granules 13, making it safe and efficient.
[0021] Through practical verification, when using a food preservation bag for home refrigerators that uses incense to consume oxygen and replenish carbon dioxide to store fruit, first wrap the fruit in a paper towel and then put it into the preservation bag. Citrus fruits can be preserved for 3 months without spoiling or rotting, and the taste is almost unchanged, only slightly sweeter; bananas can be stored for more than 4 months without changing taste; apples can be stored for a long time, for 4 and a half months, and the taste and appearance of apples are almost unchanged.
