Description

Technical Field

[0001] The present invention relates to a quantitative oil pot for quantitatively measuring edible oil. Background Art

[0002] According to the "Dietary Guidelines for Chinese Residents 2016", it is recommended that each adult consume 25g to 30g of edible oil per day. Liang Xiaofeng, the deputy director of the Chinese Center for Disease Control and Prevention, said that 80% of Chinese families exceed the standard in the amount of edible oil consumed. Excessive intake of edible oil is one of the factors contributing to overweight and obesity. Limiting the intake of edible oil is beneficial to the prevention and treatment of chronic diseases caused by obesity. Although there is a call for "reducing salt, reducing oil, and reducing sugar", the specific methods for reducing the use in daily life still rely on the experience of users. Currently, the packaging of edible oil cannot display the usage amount during daily use, which is the main reason for the excessive amount of edible oil.

[0003] Edible oil is particularly vulnerable to oxidation and rancidity due to factors such as light, heat, enzymes, and metal ions, which can damage human health. The research on the antioxidant of edible oil has progressed slowly because most natural antioxidants are water-soluble and most synthetic antioxidants are harmful to the human body. In the research on packaging bottles, a comparison of the degree of oxidation reaction of edible oil in six groups of packaging materials including glass bottles, PET, food bags, and each with TBHQ in the air shows that the barrier property of glass is the best when TBHQ is not added. When TBHQ is added, the barrier properties of the three materials are not much different. Comparatively speaking, PET (with good chemical, physical, and mechanical strength [8]) with TBHQ has more market advantages. The Barilayer-T-1 film formed by using PET film as the base material and unilaterally coating BI enhances the tensile strength, surface tension, barrier property, etc., and is used as a soft packaging material. Comparing the soft packaging bags of three mainstream soft packaging materials PET / AL / PE, NY / EVOH / PE, and PET / VMPET / PE, it is found that although the barrier properties of NY / EVOH / PE and PET / VMPET / PE soft packaging bags are better, the main factors affecting the barrier property of soft packaging are the sealing performance of the valve and the mechanical strength of the soft packaging. Among these three materials, PET / VMPET / PE has the best comprehensive performance. Currently, edible oil in PET bottles is the main product on the market, but soft packaging has more cost advantages compared to PET bottles (the cost of a 1L soft packaging bag is only 1 / 3 of that of ordinary PET materials). Soft packaging can be squeezed and deformed, and the oil can be extruded by squeezing, reducing the contact of edible oil with air and extending the shelf life. Soft packaging has a smaller capacity, making it easier to take and quantify. In plastics and composite materials, additives added to make up for the deficiencies of packaging materials will still penetrate into food under high pressure, high temperature, and long-term use, endangering health.

[0004] The development of the economy has brought about a change in concepts, and food packaging that is safe, environmentally friendly, and distinctive has received increasing attention. Using traditional culture to endow food with characteristics on food packaging to increase the added value of food is a common design used by enterprises. However, in the overall design, there are still deficiencies such as single design, relatively backward production materials and technologies. For common big brands of edible oil, such as Luhua, Golden Arowana, Fortune, Dolly, etc., most are large packages of 1-5L. But now, there are more and more personalized small packages suitable for single people, bringing more choices to people.

[0005] In shopping malls and supermarkets, most of the small packaging edible oil bottles suitable for single people are 900ml PE plastic bottles, which are similar to large packages in use and design and lack novelty. Compared with the online shopping platform, there are various small-capacity edible oil packages. The first type is the edible oil packaging based on the extrusion principle. One is to extrude the outer packaging wall to directly force out the internal oil; another is the oil outlet method based on the principle of a liquid suction machine; there is also one that squeezes the edible oil in the middle through the blocking pieces at both ends of the edible oil to discharge the oil. The second type is the edible oil packaging based on the pouring principle, and its principle is the same as that of daily large bottle edible oil packaging. To make the use of edible oil healthier, some edible oil packages also have metering components. Currently, there are two metering methods. One is to know the dosage by allowing the edible oil to flow through the metering barrel at the upper part of the packaging; the other is to observe the rotation path for quantification during extrusion. However, the main drawbacks of the above various methods are that it is inconvenient to measure, the measurement is vague, or the measurement is rigid (only a fixed volume of oil can be discharged each time). Moreover, it cannot achieve both environmental protection, sealing, and hygiene well. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a quantitative oil pot that can achieve quantitative measurement and is convenient for measurement.

[0007] To solve the above technical problem, the quantitative oil pot of the present invention includes a soft bag. The soft bag has an oil cap, and a one-way valve is arranged in the oil cap. The oil cap is connected to an oil cylinder through a pipeline, and the oil in the soft bag enters the oil cylinder through the oil cap, one-way valve, and pipeline; the soft bag is located inside a transmission device. The transmission device includes a gear ring, and the gear ring is connected to a sun gear through a number of planetary gears. The sun gear and planetary gears are fixed on a shaft, and the sun gear and planetary gears rotate on the shaft. When the gear ring rotates, the gear ring drives the planetary gears to rotate, and the planetary gears drive the sun gear to rotate; the planetary gears are connected to a screw rod, and a nut is arranged on the screw rod. The nut is connected to a lifting plate. When the planetary gears rotate, they drive the screw rod to rotate. The rotation of the screw rod drives the nut to move, and the movement of the nut drives the lifting plate to lift and lower. The soft bag is located between the screw rod and the lifting plate, and when the lifting plate rises, it squeezes the soft bag.

[0008] The one-way valve includes a blocking piece, which is arranged inside the oil cap. A blocking piece spring is arranged between the blocking piece and the bottom of the oil cap, and the blocking piece is located between the blocking piece spring and the soft bag.

[0009] For indicating the quantitative measurement, a pointer is connected to the sun gear.

[0010] To achieve the reset of the pointer, an installation ring is mounted on the sun gear, a central shaft is mounted on the installation ring, and the pointer is mounted on the central shaft; outside the central shaft, the installation ring has a tooth groove, and the surface of the central shaft has a pawl, which is mounted on the central shaft through a movable shaft; at the installation position of the pawl, the central shaft has a movable hole, the movable shaft is mounted in the movable hole, when the pawl extends out of the movable hole, the movable shaft abuts against the pawl to make the pawl located in the tooth groove; inside the movable hole, a spring is sleeved outside the movable shaft, and the spring makes the movable shaft move towards the inner side of the central shaft; a button is arranged inside the central shaft, a return shaft is connected below the button, the return shaft has a vertical section at the upper part and a conical section at the lower part, the conical section abuts against the movable shaft to make it extend out of the movable hole and abut against the pawl to make the pawl located in the tooth groove, when the return shaft descends, the spring makes the movable shaft move towards the inner side of the central shaft, the movable shaft no longer extends out of the movable hole to abut against the pawl, the pawl disengages from the tooth groove, and the vertical section abuts against the movable shaft to prevent the movable shaft from disengaging from the movable hole; a button spring is arranged below the button, and the bottom of the button spring is located on the sun gear; a torsion spring is connected to the central shaft, one end of the torsion spring is fixed (such as fixed on the following top cover), and the other end of the torsion spring is connected to the central shaft.

[0011] The oil pot has a housing and a top cover, the housing is located outside the transmission device, and the top cover is located above the transmission device.

[0012] In the present invention, the planetary gear rotates a certain angle to drive the lifting plate on the screw rod to squeeze the internal soft package, so as to achieve the purpose of quantitative measurement. Compared with the current packaging that squeezes the bottle body, uses the principle of a pressing liquid suction machine, and relies on gravity to pour, the measurement accuracy is higher.

[0018] The quantitative oil pot has a housing and a top cover (not marked in the figure). There is a transmission device inside the housing, and the top cover is above the transmission device.

[0019] As Figure 1 shown, the transmission device includes a ring gear 1. The ring gear 1 is located between the housing and the top cover. The ring gear 1 is connected to a sun gear 3 through a number of (such as three) planetary gears 2. The sun gear 3 and the planetary gears 2 are fixed on shafts (the sun gear shaft 5 and the planetary gear shaft 4 respectively), and the sun gear 3 and the planetary gears 2 rotate on the shafts. When the ring gear 1 rotates, the ring gear 1 drives the planetary gears 2 to rotate, and the planetary gears 2 drive the sun gear 3 to rotate. The planetary gear 2 is connected to a screw rod 7. There is a nut 8 on the screw rod 7. The nut 8 is connected to a lifting plate 9. When the planetary gear 2 rotates, it drives the screw rod 7 to rotate. The rotation of the screw rod 7 drives the nut 8 to move, and the movement of the nut 8 drives the lifting plate 9 to move up and down.

[0020] A soft bag 10 is placed between the screw rod 7 and the lifting plate 9. When the lifting plate 9 rises, it squeezes the soft bag 10. As Figure 2 shown, the soft bag 10 has an oil cap 11. A one-way valve is arranged inside the oil cap 11. The oil cap 11 is connected to an oil cylinder 16 through a pipeline 15. The oil in the soft bag 10 enters the oil cylinder 16 through the oil cap 11, the one-way valve and the pipeline 15. Specifically, the one-way valve includes a blocking piece 13. The blocking piece 13 is arranged inside the oil cap 11. A blocking piece spring 12 is arranged between the blocking piece 13 and the bottom of the oil cap 11. The blocking piece 13 is located between the blocking piece spring 12 and the soft bag opening 14. By rotating a certain angle of the ring gear 1 and the planetary gears 2, the lifting plate 9 on the screw rod 7 is driven to squeeze the internal soft package (i.e., the soft bag 10) to achieve the purpose of quantification.

[0021] The sun gear 3 is connected to a pointer 29 to realize the indication of the rotation angle of the sun gear 3, so as to realize the indication of the quantitative measurement. Specifically, as Figure 3 、 4 shown, an installation ring is installed on the sun gear 3. The installation ring is composed of a lower block 17, a middle block 18 and an upper block 19. The lower block 17 is installed inside the sun gear 3 and is fixed to the long groove 6 on the sun gear 3 through a long convex block 20. As Figure 3As shown, the lower block 17 and the middle block 18 are connected together by teeth, and the upper block 19 is installed inside the middle block 18 and fixedly connected through the middle bump 21 and the middle groove 22. The upper block 19 has a tooth groove 23, and a middle shaft 33 (located in the middle of the upper block 19) is installed on the middle block 18, and the pointer 29 is installed on the middle shaft 33; outside the middle shaft 33, the upper block 19 has a tooth groove 23, and the surface of the middle shaft 33 has a pawl 24, and the pawl 24 is installed on the middle shaft 33 through a movable shaft 25; at the installation position of the pawl 24, the middle shaft 33 has a movable hole (not marked), and the movable shaft 26 is installed in the movable hole. When the pawl 24 extends out of the movable hole, the movable shaft 26 abuts against the pawl 24 to make the pawl 24 located in the tooth groove 23; inside the movable hole, a spring 27 is sleeved outside the movable shaft 26, and the spring 27 makes the movable shaft 26 move towards the inner side of the middle shaft 33; a button 31 is arranged inside the middle shaft 33, a return shaft 28 is connected below the button 31, and the return shaft 28 has a vertical section (not marked) at the upper part and a conical section at the lower part. The conical section abuts against the movable shaft 26 to make it extend out of the movable hole and abut against the pawl 24, so that the pawl 24 is located in the tooth groove 23, and the middle shaft 33 rotates together with the sun gear 3 to realize the rotation of the pointer 29.

[0022] When the return shaft 28 descends under the pressing of the button, without the reliance of the protruding conical section (the diameter of the conical section is larger than that of the vertical section) of the movable shaft 26, under the action of the spring 27, the movable shaft 26 moves towards the inner side of the middle shaft 33, and the movable shaft 26 no longer extends out of the movable hole to abut against the pawl 24, and the pawl 24 disengages from the tooth groove 23. At the same time, the vertical section abuts against the movable shaft 26 to prevent the movable shaft 26 from disengaging from the movable hole. A button spring 32 is arranged below the button 31, and the bottom of the button spring 32 is located on the sun gear (serving as the reference of the button spring 32). After the button 31 is pressed, the button spring 32 makes the button 31 reset upwards; a torsion spring 30 is connected to the middle shaft 33, one end of the torsion spring 30 is fixed (fixed on the top cover), and the other end of the torsion spring 30 is connected to the middle shaft 33.

[0023] When the mounting ring rotates with the sun gear 3, since the pawl 24 is located in the tooth groove 23, the middle shaft 33 rotates with the mounting ring, and the pointer 29 on the middle shaft 33 indicates the rotation angle. At this time, the torsion spring 30 generates torque or rotational force due to the rotation of the middle shaft 33. When the button 31 is pressed, the return shaft 28 descends, and the spring 27 makes the movable shaft 26 move towards the inner side of the middle shaft 33. The movable shaft 26 no longer extends out of the movable hole to abut against the pawl 24, and the pawl 24 disengages from the tooth groove 23. Under the force of the torsion spring 30 restoring to its original state, the middle shaft 33 rotates and resets, and the pointer 29 on the middle shaft 33 follows the reset.

[0024] The above embodiments do not limit the present invention in any way. All technical solutions obtained by means of equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
