Description

Technical Field

[0001] This invention relates to the field of packaging technology, and particularly to the field of sealed packaging products, specifically an edible oil anti-oxidation oil bottle. Background Technology

[0002] Edible oils are rich in polyunsaturated fatty acids, which are easily oxidized. When polyunsaturated fatty acids are exposed to air, they oxidize to form peroxides, which then decompose into short-chain aldehydes, ketones, acids, and other small molecule compounds, producing a strong, pungent odor. To prevent or slow down the deterioration of edible oils, measures such as adding antioxidants, low temperature, protection from light, and airtight storage are usually taken to mitigate oxidation.

[0003] Currently, adding antioxidants is often used to extend the shelf life and storage time of oils. There are many types of antioxidants, such as BHT, BHA, PG, and TBHQ. These artificially synthesized antioxidants pose potential harm to the human body and may cause tissue cancer. When antioxidants work, the free radicals produced by oxidation are inhibited or eliminated by the antioxidants. However, when the antioxidants are depleted, the rate of free radical generation accelerates, which can actually accelerate the oxidative rancidity of edible oils in the later stages of storage.

[0004] During the storage of oils, the likelihood of oil oxidation increases whenever oxygen is present. Therefore, isolating oils from air (oxygen) is fundamental and crucial for preventing oxidation, rancidity, and maintaining freshness.

[0005] In the storage and packaging of liquids, some liquids also need to be preserved in the absence of oxygen. Existing preservation methods usually involve filling them with inert gas or nitrogen, or using vacuum packaging. For liquids that need to be used in small doses and frequently, small vacuum packaging is usually used for preservation. Each time it is used, the packaging is opened and used quickly, and then the air in the packaging bag is squeezed out and the packaging bag is closed. This operation is very complicated and can easily cause a small amount of air to remain in the packaging bag, affecting the quality of the packaged liquid.

[0006] Furthermore, some liquids are hygroscopic or volatile, posing a risk of leakage and requiring a high degree of sealing. In cases of frequent use and frequent dispensing, there are no suitable packaging materials available. Summary of the Invention

[0007] This invention addresses the current problem that edible oil needs to be kept away from air during daily storage, while also requiring frequent opening and pouring. For this type of liquid that is frequently opened and needs to be kept fresh without oxygen, there is no suitable and stable packaging container. Existing small packaging designs have a series of problems such as cumbersome operation and high cost. To meet the needs of household oil use, this invention provides an anti-oxidation oil bottle for edible oil.

[0008] This invention is achieved using the following technology: This invention provides an edible oil anti-oxidation oil dispenser, including a dispenser body, a top cover fitted at the top opening of the dispenser body, a dust cover rotatably connected to one end of the top cover to cooperate with the spout, a packaging bag placed inside the dispenser body, an oil suction tube inside the packaging bag, the oil suction tube being connected to an oil suction connecting pipe at the opening of the packaging bag via an adapter, the oil suction connecting pipe being connected to the inlet of an electric diaphragm pump, the outlet of the electric diaphragm pump being connected to an oil outlet pipe, the free end of the oil outlet pipe extending to the spout; the electric diaphragm pump is controlled to open and close via a control device.

[0009] In implementation, the device includes a kettle body to keep the packaging bag upright for easy use and to improve its appearance. Materials can include plastic, glass, tinplate, aluminum alloy, stainless steel, etc. The shape can be kettle-shaped, cup-shaped, etc. A removable lid is attached to the top opening of the kettle body for easy bag replacement. A dust cover that mates with the spout is rotatably connected to one end of the lid. The packaging bag is placed inside the kettle body. The bag is a thin film bag made of aluminized PET and nylon composite materials, utilizing its airtight sealing properties while being relatively soft and easily foldable. It overcomes the negative pressure generated by oil extraction without air intake, allowing the edible oil inside the bag to be smoothly extracted or poured out. The packaging bag is replaceable and detachable, which is beneficial for storage and replacement. The packaging bag has an internal oil suction tube, which is connected to the oil suction connecting pipe at the bag opening via an adapter, making it convenient and reliable. The connection between the bag opening and the oil suction connecting pipe can also use other sealing connection methods. The oil suction connecting pipe is connected to the inlet of the electric diaphragm pump, and the outlet of the electric diaphragm pump is connected to the oil outlet pipe. The free end of the oil outlet pipe extends to the spout. The electric diaphragm pump is controlled by a control device to open and close.

[0010] Furthermore, the control device includes a power supply, with a power switch connected to the positive terminal of the power supply. The power switch acts as the master switch, ensuring that oil will not be dispensed when tilted at any angle during transportation or when not in frequent use, thus preventing liquid from spraying out during movement. The power switch is connected to the positive terminal of the micro DC motor of the electric diaphragm pump. The micro DC motor is a 3.7V DC motor. An oil pump tilt switch is connected to the line connecting the negative terminal of the micro DC motor and the negative terminal of the power supply. The tilt switch is activated when its tilt angle is greater than a preset angle. The oil pump tilt switch is installed at an angle of 45°, which can be set according to usage. When the tilt angle of the oil reservoir is greater than 45°, the diaphragm pump operates.

[0011] Furthermore, after the power supply is connected to the power switch, it is connected to the positive terminal of the electromagnet assembly. The electromagnet assembly includes a miniature 3.7V DC electromagnet. A push rod is fixed to the iron core of the electromagnet assembly facing the spout. The push rod rests against the dust cover. The cross-section of the dust cover is a horizontally placed "7" shape. There are pivots at the bends of the short and long parts. The push rod pushes the short part outward and the long part flips upward, opening the dust cover. When the electromagnet assembly is energized, the iron core of the electromagnet assembly is attracted to the spout. A flip-top tilt switch is connected to the connection line between the negative terminal of the electromagnet assembly and the negative terminal of the power supply. The tilt angle of the flip-top tilt switch is greater than the preset angle to connect the circuit. The flip-top tilt switch is installed at an angle of 10°.

[0012] Both the oil extraction tilt switch and the flip cover tilt switch are tilt switches. The tilt switch has a rolling mercury ball inside the cavity. A mercury contact is provided at the upper end of the cavity. When the tilt switch is tilted, the rolling mercury ball controls the opening and closing of the switch. The tilt angle of the flip cover tilt switch is greater than that of the oil extraction tilt switch.

[0013] When in use, turn on the power switch and hold the oil can to start tilting. When the oil can is tilted more than 10°, the flip-top tilt switch will gradually transition the oil can from tilted to horizontal. The mercury droplet rolls in the cavity. When the mercury droplet rolls to the mercury contact point, the circuit is connected. That is, the positive terminal of the power supply is connected to the positive terminal of the electromagnet assembly after passing through the power switch, and the negative terminal of the electromagnet assembly is connected to the power supply after passing through the flip-top tilt switch, forming a circuit. When the electromagnet assembly is energized, the iron core in the electromagnet assembly is drawn inward, the push rod fixed on the iron core extends, the dust cover is lifted, and the oil is ready to be dispensed.

[0014] Continue tilting. When the oil can is tilted more than 45°, the oil tilting switch gradually transitions from tilted to horizontal. The mercury droplet rolls in the cavity. When the mercury droplet rolls to the mercury contact point, the circuit is connected. That is, the positive terminal of the power supply is connected to the positive terminal of the micro DC motor after passing through the power switch, and the negative terminal of the micro DC motor is connected to the oil tilting switch and then connected to the power supply to form a circuit. The electric diaphragm pump is powered on and runs, drawing the oil out of the packaging bag.

[0015] Conversely, after oil discharge is completed and during the recovery and leveling process, if the tilt angle is less than 45°, the electric diaphragm pump is de-energized and oil discharge stops; if the tilt angle is less than 10°, the electromagnet assembly is de-energized, the push rod retracts, and the dust cover closes.

[0016] When all the oil in the packaging bag has been extracted, the packaging bag needs to be replaced. Remove the top cap, discard the old packaging bag, and replace it with the pre-installed cap of the new packaging bag.

[0017] Furthermore, a semi-automatic control system is adopted. The control device includes a power supply, which is a lithium battery. The positive and negative terminals of the power supply are connected to the positive and negative terminals of the micro DC motor of the electric diaphragm pump. An oil pumping tilt switch is connected to the connection line between the positive terminal of the power supply and the micro DC motor. The oil pumping tilt switch is installed at an angle of 45°, which can be set according to the usage. A limit switch is connected to the connection line between the negative terminal of the power supply and the micro DC motor. Opening the dust cover triggers the limit switch to connect the circuit.

[0018] When in use, the dust cover needs to be opened manually. When the dust cover is opened, the limit switch is pressed down, and the oil can is tilted. When the oil can is tilted more than 45°, the oil pump tilt switch is activated, the circuit is closed, that is, the positive terminal of the power supply is connected to the positive terminal of the micro DC motor after the oil pump tilt switch is connected, and the negative terminal of the power supply is connected to the negative terminal of the micro DC motor after the limit switch is connected. The diaphragm pump runs and the oil flows out.

[0019] This invention also provides a container for an anti-oxidation edible oil dispenser, comprising a dispenser body, a top cover fitted at the top opening of the dispenser body, a dust cover rotatably connected to one end of the top cover to cooperate with the spout, a packaging bag placed inside the dispenser body, the opening of the packaging bag being connected to the inlet of a solenoid valve via an adapter, the outlet of the solenoid valve being connected to an oil outlet pipe, the free end of the oil outlet pipe extending to the spout; the solenoid valve is controlled to open and close by a control device, the control device including a power supply, the positive and negative terminals of the power supply being connected to the positive and negative terminals of the valve solenoid of the solenoid valve, an oil extraction tilt switch being connected to the connection line between the positive terminal of the power supply and the valve solenoid, when the tilt angle of the dispenser body is greater than 90°, the oil extraction tilt switch is activated, to prevent the solenoid valve from opening too early or closing too late and allowing air to enter the packaging bag, the oil extraction tilt switch is installed vertically, the negative terminal of the power supply being connected to a limit switch being connected to the connection line between the power supply and the valve solenoid, the opening of the dust cover triggers the limit switch to activate the circuit.

[0020] When using the product, the dust cover needs to be opened manually. When the dust cover is opened, the limit switch is pressed down, and the oil can is tilted. When the oil can is tilted at an angle of 90° or more, that is, when the oil can is tilted from a vertical position to a horizontal position, the oil extraction tilt switch is activated, and the circuit is closed. That is, the positive terminal of the power supply is connected to the positive terminal of the valve solenoid after the oil extraction tilt switch, and the negative terminal of the power supply is connected to the negative terminal of the valve solenoid after the limit switch. The solenoid valve opens and oil is dispensed. When the oil can is tilted at an angle of less than or equal to 90°, the solenoid valve closes, and air will not enter the packaging bag.

[0021] The present invention also provides a container for an anti-oxidation oil jug, comprising a jug body, a handle fixed to the side wall of the jug body, a top cover snapped onto the top opening of the jug body, a packaging bag placed inside the jug body, the opening of the packaging bag being connected to the inlet of a manual valve, the outlet of the manual valve extending into the spout of the jug body, the spout being covered with a dust cover, and the top of the push-pull rod of the manual valve extending out of the top cover and connecting to a drive component, so that oil can be manually drawn out from the packaging bag.

[0022] In implementation, the device includes a kettle body with a handle fixed to its side wall. A top cover is fitted onto the top opening of the kettle body. A packaging bag is placed inside the kettle body, with its opening connected to the inlet of a manual valve. The manual valve is a pull-type valve, with its outlet extending into the spout of the kettle body. A dust cover is attached to the top of the top cover via a connecting strap. The push-pull rod of the manual valve extends beyond the top cover and connects to a drive mechanism. The push-pull rod is a pull rod, and a button is rotatably mounted on its extension. The drive mechanism is a button with a rotating shaft in the center. The short arm of the button rests against a protrusion on the outer wall of the top cover, which acts as a fulcrum. The long arm of the button is located directly above the handle. Oil is manually drawn from the packaging bag. During use, the device operates by opening and closing the oil outlet when it is lower than the oil level inside the kettle, preventing air from entering the packaging and ensuring a tight seal.

[0023] When using, to prevent air from entering, tilt the oil can more than 90 degrees, press the button downwards with your thumb. The long arm of the button will press down, the protrusion will support the short arm, and the rotating shaft will pull the lever outwards while rotating. The pull-type manual valve will draw the liquid out of the packaging bag and output the oil from the spout.

[0024] During implementation, a handle is fixed to the side wall of the kettle body, and a top cover is snapped onto the top opening of the kettle body. A packaging bag is placed inside the kettle body, and the opening of the packaging bag is connected to the inlet of the manual valve. The outlet of the manual valve extends into the spout of the kettle body. The manual valve is a push-type manual valve. A dust cover is placed on the top of the spout, and the dust cover is installed on the top of the top cover via a connecting strap. The top of the push-pull rod of the manual valve extends out of the top cover and connects to the drive component. The push-pull rod is a push rod, and a button is fixed to the top of the push rod extending out of the top cover. Oil is extracted from the packaging bag by manual oil extraction.

[0025] When in use, tilt the oil can more than 90 degrees, press the button directly downwards with your thumb. The button pushes the push rod inwards, and the push-type manual valve draws the liquid out of the packaging bag and outputs the oil from the spout.

[0026] This invention also provides an edible oil anti-oxidation oil dispenser, including a dispenser body, a handle fixed to the side wall of the dispenser body, a top cover snapped onto the top opening of the dispenser body, a packaging bag placed inside the dispenser body, the opening of the packaging bag connected to the inlet of a double-connected one-way valve, the metering port of the double-connected one-way valve connected to a metering device through a metering oil pipe, the metering device having a structure similar to an injection syringe, a piston rod installed in the metering cylinder, the oil being drawn and discharged by pulling the piston rod, the metering device can be installed on the top of the oil dispenser, or installed on the side of the dispenser as a handle, or placed inside the dispenser with the piston rod protruding from the lid, and the metering scale marked on the piston rod.

[0027] Specifically, the double-port check valve has two interconnected chambers, a lower chamber and an upper chamber. The bottom of the lower chamber has an inlet that connects to an oil suction pipe for drawing liquid from the packaging bag. The upper part of the lower chamber has a metering port, through which oil in the lower chamber can enter a metering device to measure the amount of oil drawn. The top of the lower chamber is connected to the bottom of the upper chamber, and the side of the upper chamber has an outlet. Both chambers are fitted with small balls that are used to block the openings via spring tops. The ball top of the lower chamber is installed at the inlet, and the ball top of the upper chamber is installed at the connection between the upper and lower chambers. The outlet of the double-port check valve extends into the spout of the vessel body, and the spout is covered with a dust cover, which is installed on the top of the upper cover via a connecting strap.

[0028] When in use, the piston rod of the metering device is pulled, and the oil enters the metering cylinder of the metering device through the suction pipe, the lower chamber, and the metering oil pipe. When the required amount is drawn, the piston rod of the metering device is pushed, and the oil is discharged from the metering cylinder of the metering device. It enters the lower chamber of the double check valve through the metering oil pipe. In the lower chamber, it pushes open the small ball in the upper chamber and enters the upper chamber. Finally, it flows out from the outlet.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] This invention relates to an anti-oxidation oil dispenser for cooking oil, providing a suitable anti-oxidation oil dispenser for household use, which is beneficial to human health. This device also provides a scheme to control the amount of oil used, allowing users to use the correct amount of oil to prevent excessive use. Over time, this can avoid the health problems caused by excessive oil consumption.

[0031] This device has the following advantages:

[0032] First, it prevents oxidation. Edible oil packaged using this device does not come into contact with air during storage and use, fundamentally solving the problem of easy oxidation of oils. Because it is isolated from air, there is no need to use antioxidants, greatly extending the shelf life of edible oils. This not only benefits oil manufacturers in terms of cost control, but also benefits the health of consumers and users, overcoming the major problem of people accidentally consuming oil with excessive peroxide values, which is the biggest advantage and most important function of this device.

[0033] Second, the operation is simple. The fully automatic operation of this device is exactly the same as that of a regular oil dispenser (cup). The oil pouring process is identical, requiring no additional operation. Simply pick up the oil dispenser, tilt it slightly, and the dust cover will automatically open. Continue tilting to a certain angle, and the oil will flow out. After pouring out the required amount, return the oil dispenser to its original position; the oil will stop flowing, and the dust cover will automatically close. Then, simply put the oil dispenser back in its place. The semi-automatic version only requires manually opening the dust cover before pouring and closing it afterward. Operation is simple, convenient, and quick.

[0034] Third, it has a pleasing appearance. Compared with the anti-oxidation cooking oil bottle with a squeeze-fold body, this device does not require a folding oil can shell and always maintains a perfect overall appearance.

[0035] Fourth, the cost is relatively low. Using this device, composite film packaging bags replace existing small plastic oil drums. In practice, it's essentially a replacement of the composite film packaging bags; after the edible oil is used up, the used composite film bag is discarded and replaced with a new, factory-sealed bag of oil. The outer shell and lid of the device can be used indefinitely. Because the composite film packaging bags used in this device have higher hygiene standards than existing small plastic oil drums and are cheaper, they are welcomed by edible oil manufacturers and consumers.

[0036] In addition, this device can also be more widely used in liquids with high flow index that need to be isolated from air or have reduced contact with air for preservation, such as volatile liquids, hygroscopic liquids, cosmetic products, etc. It is suitable for liquid storage containers of different capacities and has a wide range of applications.

Implementation

[0055] The specific embodiments of the present invention will be described in detail below. Example 1

[0056] An anti-oxidation oil dispenser for cooking oil, such as Figures 1-3As shown, the device includes a pot body 1, which keeps the packaging bag 2 upright for easy use and to improve its appearance. The pot body 1 can be made of materials such as plastic, glass, tinplate, aluminum alloy, stainless steel, etc., and its shape can be pot-shaped, cup-shaped, etc. A top cover 3 is snapped onto the top opening of the pot body 1. The top cover is removable for easy replacement of the packaging bag. A dust cover 7 that mates with the spout is rotatably connected to one end of the top cover 3. The packaging bag 2 is placed inside the pot body 1. The packaging bag 2 is a thin film bag made of composite materials such as aluminized PET and nylon. It utilizes its airtight sealing properties and its relatively soft and foldable nature to overcome the problem of leakage. The negative pressure created by preventing air from entering the oil allows the edible oil inside the bag to be easily extracted or poured out. The packaging bag is replaceable and detachable, which is beneficial for storage and replacement. The packaging bag 2 has an internal oil suction tube 16, which is connected to the oil suction connecting pipe 9 at the opening 4 of the packaging bag via an adapter 5. This connection is convenient and reliable. The connection between the opening 4 of the packaging bag and the oil suction connecting pipe 9 can also use other sealing connection methods, which can be quickly sealed. The oil suction connecting pipe 9 is connected to the inlet of the electric diaphragm pump, and the outlet of the electric diaphragm pump is connected to the oil outlet pipe 6. The free end of the oil outlet pipe 6 extends to the spout. The electric diaphragm pump is controlled by a control device to open and close.

[0057] like Figure 2 As shown, the control device is installed in the upper cover 3. The control device includes a power supply 15, which uses a rechargeable lithium battery. For the sake of simplicity and clarity in the drawing, the charging module is not shown. Based on this, a timing module can be added to create a smart, quantitative household appliance. This allows control over the amount of oil dispensed each time by setting a time interval. Existing technology in this area is mature and will not be elaborated further. The positive terminal of the power supply 15 is connected to a power switch 13, which acts as the master switch, ensuring that oil will not dispense when tilted at any angle during transportation or infrequent use, preventing liquid from spraying out during movement. The power switch 13 is connected to the positive terminal of the micro DC motor 14 of the electric diaphragm pump. The micro DC motor 14 is a 3.7V DC motor. An oil suction tilt switch 12 is connected to the negative terminal of the micro DC motor 14 and the negative terminal of the power supply. Figure 1 As shown, the oil pump tilt switch 12 is installed at an angle of 45°. The installation angle can be set according to usage habits. When the tilt angle of the oil reservoir is greater than 45°, the tilt angle of the oil pump tilt switch 12 is greater than the preset angle, which connects the circuit and the diaphragm pump 11 of the electric diaphragm pump starts to operate.

[0058] As another circuit, such as Figure 2 , 3As shown, after the power supply 15 is connected to the power switch 13, it is connected to the positive terminal of the electromagnet assembly 8. The electromagnet assembly 8 includes a miniature 3.7V DC electromagnet. A push rod is fixed on the iron core of the electromagnet assembly 8 facing the spout. The push rod rests against the dust cover 7. The cross-section of the dust cover 7 is a horizontally placed "7" shape. A pivot is provided at the bend connection between the short and long parts. The push rod pushes the short part outward and the long part flips upward, opening the dust cover 7. When the electromagnet assembly 8 is energized, the iron core of the electromagnet assembly 8 is attracted to the spout. A flip-top tilt switch 10 is connected to the connection line between the negative terminal of the electromagnet assembly 8 and the negative terminal of the power supply 15. The flip-top tilt switch 10 is installed at an angle of 10°. When the tilt angle of the flip-top tilt switch 10 is greater than the preset angle, the circuit is connected.

[0059] Both the oil extraction tilt switch 12 and the flip cover tilt switch 10 are tilt switches. The tilt switch has a rolling mercury ball inside the cavity. The upper end of the cavity is provided with a mercury contact. When the tilt switch is tilted, the rolling mercury ball controls the opening and closing of the switch. The tilt angle of the flip cover tilt switch 10 is greater than that of the oil extraction tilt switch 12, ensuring that the dust cover 7 is opened first before oil is extracted when tilting, thus avoiding contamination of the dust cover 7.

[0060] This embodiment uses fully automatic control. The operation method is exactly the same as the tilting action of an ordinary oil can. However, two parallel circuits are used to control the opening of the dust cover 7 and the oil dispensing. The oil dispensing is achieved by using an electric diaphragm pump to extract the oil, which can achieve the sealing of the oil can.

[0061] When in use, turn on the power switch 13 and hold the oil can to start tilting. When the oil can is tilted more than 10°, the flip-top tilt switch 10 gradually transitions from tilted to horizontal as the oil can is tilted. The mercury droplet rolls in the cavity. When the mercury droplet rolls to the mercury contact point, the circuit is connected. That is, the positive terminal of the power supply 15 is connected to the positive terminal of the electromagnet assembly 8 through the power switch 13, and the negative terminal of the electromagnet assembly 8 is connected to the flip-top tilt switch 10 and then to the power supply 15 to form a circuit. When the electromagnet assembly 8 is energized, the iron core in the electromagnet assembly 8 is drawn inward (moving to the left in the figure). The push rod fixed on the iron core extends, the dust cover 7 is lifted, and the oil is ready to be dispensed.

[0062] Continue tilting. When the oil can is tilted more than 45°, the oil tilting switch 12 gradually transitions from tilted to horizontal as the oil can moves. The mercury droplet rolls in the cavity. When the mercury droplet rolls to the mercury contact point, the circuit is connected. That is, the positive terminal of the power supply 15 is connected to the positive terminal of the micro DC motor 14 through the power switch 13, and the negative terminal of the micro DC motor 14 is connected to the oil tilting switch 12 and then to the power supply 15 to form a circuit. The electric diaphragm pump is powered on, and the diaphragm pump 11 runs to extract the oil from the packaging bag 2.

[0063] Conversely, after oil discharge is completed and during the process of restoring the flat position, if the tilt angle is less than 45°, the electric diaphragm pump 11 is de-energized and stops discharging oil; if the tilt angle is less than 10°, the electromagnet assembly 8 is de-energized, the push rod retracts, and the dust cover 7 closes.

[0064] When all the oil in packaging bag 2 has been extracted, the packaging bag needs to be replaced. Remove the top cover, discard the old packaging bag, and replace it with the pre-installed cap of the new packaging bag. Example 2

[0065] An anti-oxidation oil dispenser for cooking oil, such as Figures 4-6 As shown, this embodiment adopts semi-automatic control compared to embodiment 1. It uses a limit switch 17 to replace the flip-top tilt switch 10 and electromagnet assembly 8 in embodiment 1, resulting in lower manufacturing costs, lower power consumption, and suitability for long-term use. The structure and fixing method of the kettle body 1 and upper cover 3 in this embodiment are the same as in embodiment 1, but the control device is different. The control device is installed in the upper cover 3 and includes a power supply 15, which uses a lithium battery. The positive and negative terminals of the power supply 15 are connected to the positive and negative terminals of the micro DC motor 14 of the electric diaphragm pump. An oil-pulling tilt switch 12 is connected to the connection line between the positive terminal of the power supply 15 and the micro DC motor 14. The oil-pulling tilt switch 12 is installed at an angle of 45°, which can be set according to usage. A limit switch 17 is connected to the connection line between the negative terminal of the power supply 15 and the micro DC motor 14. Opening the dust cover 7 triggers the limit switch 17 to connect the circuit. Figure 6 As shown, specifically, one end of the dust cover 7 is rotatably mounted on the upper cover 3, and the long part covers the spout. The edge of the long part can be provided with a protrusion or an extended edge to facilitate hand operation, so as to avoid contaminating the spout when the dust cover 7 is flipped up. A connecting device can also be used here, so that the spout can be opened by holding the handle, realizing one-handed operation. This technology is relatively mature in the existing technology and will not be described in detail. The free end of the short part is rolled up, and the triggering device of the limit switch 17 is provided below the short part. When the short part rotates downward around the axis, the triggering device of the limit switch 17 is triggered.

[0066] When in use, the dust cover 7 needs to be opened manually. When the dust cover 7 is opened, it rotates, the long part folds upward, and the short part rotates accordingly, pressing down the limit switch 17. The limit switch 17 closes, and the oil can is tilted. When the oil can is tilted more than 45°, the oil suction tilt switch 12 is activated, and the circuit is closed. That is, the positive terminal of the power supply 15 is connected to the positive terminal of the oil suction tilt switch 12 and then to the positive terminal of the micro DC motor 14, and the negative terminal of the power supply 15 is connected to the negative terminal of the micro DC motor 14 after the limit switch 17. The diaphragm pump 11 operates, and the oil enters the diaphragm pump 11 from the oil suction pipe 19 through the adapter 5 and the oil suction connecting pipe 9. The diaphragm pump 11 delivers the oil from the oil outlet pipe 6 to the spout, and the oil flows out. Example 3

[0067] An anti-oxidation oil dispenser for cooking oil, such as Figures 7-9As shown, the device includes a kettle body 1, with a top cover 3 fitted onto the top opening of the kettle body 1. A dust cover 7, which rotatably connects to the top end of the top cover 3 and mates with the spout, is attached to the top. A packaging bag 2 is placed inside the kettle body 1. The opening 4 of the packaging bag 2 is connected to the inlet of a solenoid valve 18 via an adapter 5, achieving a sealed installation. The outlet of the solenoid valve 18 is connected to an oil outlet pipe 6, with the free end of the oil outlet pipe 6 extending to the spout. The solenoid valve 18 is controlled to open and close by a control device installed in the top cover 3. The control device includes a power supply 15, which is a lithium battery. The positive and negative terminals of the power supply 15 are connected to the positive and negative terminals of the valve electromagnet 19 of the solenoid valve 18. A sliding oil tilt switch 12 is connected to the connection line between the positive terminal of power source 15 and the valve solenoid 19. In order to prevent the solenoid valve 18 from opening too early or closing too late and causing air to enter the packaging bag, the structure of the sliding oil tilt switch 12 is exactly the same as that in embodiment 1. However, in this embodiment, the sliding oil tilt switch 12 is installed vertically. When the tilt angle of the pot body 1 is greater than 90°, that is, when the pot body is rotated to the horizontal direction, the sliding oil tilt switch 12 connects the circuit. A limit switch 17 is connected to the connection line between the negative terminal of power source 15 and the valve solenoid 19. When the dust cover 7 is opened, it triggers the limit switch 17 to connect the circuit. The connection between the limit switch 17 and the dust cover 7 is the same as that in embodiment 2, and will not be described in detail.

[0068] This embodiment is the same as embodiment 2, using semi-automatic control. The structure and connection method of the pot body 1 and the upper cover 3 are the same as those in embodiments 1 and 2. However, this embodiment does not require the use of an oil suction pipe, making installation and use more hygienic and convenient.

[0069] When using, the dust cover 7 needs to be opened manually. Flip the dust cover 7 up to open it. Press the limit switch 17 down with the dust cover 7, and the limit switch 17 will close. Hold the oil can and start tilting it. When the oil can is tilted at an angle greater than or equal to 90°, that is, when the oil can is tilted from a vertical position to a horizontal position, or even slightly more than horizontal, the oil suction tilt switch 12 will be activated, and the circuit will be closed. That is, the positive terminal of the power supply 15 is connected to the positive terminal of the valve solenoid 19 after the oil suction tilt switch 12, and the negative terminal of the power supply 15 is connected to the negative terminal of the valve solenoid 19 after the limit switch 17. The solenoid valve 18 will open and oil will be dispensed. Conversely, when the oil can is tilted at an angle less than or equal to 90°, the solenoid valve 18 will close and oil will stop dispensing. Manually close the dust cover 7 to prevent air from entering the packaging bag and keep the liquid inside the packaging bag sealed. Example 4

[0070] An anti-oxidation oil dispenser for cooking oil, such as Figure 10 , 11As shown, this embodiment employs manual control and includes a kettle body 1. A handle is fixed to the side wall of the kettle body 1. A top cover 3 is snapped onto the top opening of the kettle body 1. A packaging bag 2 is placed inside the kettle body 1. The opening of the packaging bag 2 is connected to the inlet of a manual valve. The manual valve is a pull-type manual valve 20. The outlet of the manual valve extends into the spout of the kettle body 1. A dust cover 7 is placed on the spout. The dust cover 7 is installed on the top of the top cover 3 via a connecting strap to prevent the dust cover 7 from being lost. The top of the push-pull rod of the manual valve extends out of the top cover 3 and connects to a driving component. In this embodiment, the push-pull rod is a pull rod 21. A button 22 is rotatably installed on the pull rod 21 extending out of the top of the top cover 3. The driving component is the button 22. A rotating shaft is provided in the middle of the button 22. The short arm of the button 22 rests against a protrusion on the outer wall of the top cover 3. The protrusion acts as a fulcrum. The long arm of the button 22 is located directly above the handle. Oil is extracted from the packaging bag by manual oil extraction. This device opens and closes when the oil outlet is lower than the oil level inside the container, preventing air from easily entering the packaging and ensuring a tight seal.

[0071] In use, to prevent air from entering, tilt the oil can more than 90°, press button 22 downwards with your thumb. The long arm of button 22 presses down, the protrusion supports the short arm, and the rotating shaft pulls the lever 21 outwards while rotating. The pull-type manual valve 20 draws the liquid out of the packaging bag and outputs the oil from the spout. Example 5

[0072] An anti-oxidation oil dispenser for cooking oil, such as Figure 12 , 13 As shown, the structures of this embodiment and embodiment 4 are the same except for the manual valve, push-pull rod and driving component.

[0073] A handle is fixed to the side wall of the kettle body 1. A top cover 3 is snapped onto the top opening of the kettle body 1. A packaging bag 2 is placed inside the kettle body 1. The opening of the packaging bag 2 is connected to the inlet of a manual valve. The outlet of the manual valve extends into the spout of the kettle body 1. The manual valve is a push-type manual valve 23. A dust cover 7 is placed on the top of the spout. The dust cover 7 is installed on the top of the top cover 3 via a connecting strap. The top of the push-pull rod of the manual valve extends out of the top cover 3 and is connected to a drive component. The push-pull rod is a push rod 24. A button 25 is fixed to the top of the push rod 24 extending out of the top of the top cover 3. Oil is extracted from the packaging bag by manual oil extraction.

[0074] When in use, tilt the oil can more than 90° and press the button 25 directly downwards with your thumb. The button 25 pushes the push rod 24 inwards, and the push-type manual valve 23 draws the liquid out of the packaging bag and outputs the oil from the spout.

[0075] Both this embodiment and Embodiment 4 are manual control devices. The manual valve does not require electricity, is easy to operate, and is suitable for use when taking small amounts of goods at long intervals. Example 6

[0076] An anti-oxidation oil dispenser for cooking oil, such as Figure 14 , 15 As shown, the device includes a container body 1, with a handle fixed to its side wall. A top cover 3 is fitted onto the top opening of the container body 1. A packaging bag 2 is placed inside the container body 1, and the opening of the packaging bag 2 is connected to the inlet of a double-check valve 26. The metering port of the double-check valve 26 is connected to a metering device 27 via a metering oil pipe 28. The metering device has a structure similar to a syringe, with a piston rod installed inside the metering cylinder. The oil is drawn and discharged by pulling the piston rod. The metering device 27 can be installed on the top of the oil container.

[0077] Specifically, the double-port check valve 26 has two interconnected chambers, a lower chamber and an upper chamber. The bottom of the lower chamber has an inlet connected to an oil suction pipe for drawing liquid from the packaging bag. The upper part of the lower chamber has a metering port, through which the oil in the lower chamber can enter the metering device 27 to measure the amount of oil drawn. The top of the lower chamber is connected to the bottom of the upper chamber, and the side of the upper chamber has an outlet. Both chambers are fitted with small balls for blocking the openings via spring tops. The small ball top of the lower chamber is installed at the inlet, and the small ball top of the upper chamber is installed at the connection between the upper and lower chambers. The outlet of the double-port check valve 26 extends into the spout of the vessel body 1. The spout is covered with a dust cover 7, which is installed on the top of the upper cover 3 via a connecting strap.

[0078] In use, the piston rod of the metering device 27 is pulled, and the oil enters the metering cylinder of the metering device 27 through the lower chamber via the oil suction pipe 16 and the metering oil pipe 28. When the required amount is drawn, the piston rod of the metering device 27 is pushed, and the oil is discharged from the metering cylinder of the metering device 27. It then enters the lower chamber of the double check valve 26 through the metering oil pipe 28. In the lower chamber, the small ball in the upper chamber is pushed open, and the oil enters the upper chamber and finally flows out from the outlet. Example 7

[0079] An anti-oxidation oil dispenser for cooking oil, such as Figure 16 , 17 As shown, except that the measuring device 27 is installed on the side of the pot as a handle, the rest is completely the same as in Example 6.
