Description

Technical Field

[0001] This application relates to the field of vacuum packaging technology, and more specifically to a vacuum packaging machine. Background Technology

[0002] As people's living standards continue to improve, the demand for food preservation is also increasing. Among various preservation methods, vacuum packaging stands out due to its convenience, low price, good preservation effect, and long preservation period, gradually moving from the commercial preservation field into ordinary households and gaining widespread user recognition. Therefore, various small vacuum packaging machines have appeared on the market to meet the food preservation needs of home users. The working principle of a vacuum packaging machine is to use a vacuum pump to extract air from the packaging bag, reducing the oxygen content inside the packaging, inhibiting the growth and reproduction of microorganisms, delaying the oxidation and spoilage of food, and thus maintaining the freshness and hygiene of the food. After completing the vacuuming operation, the heat-sealing component heat-seals the bag opening to ensure that the vacuum environment is maintained, further extending the food's shelf life. This type of small vacuum packaging machine is not only easy to operate but also compact, making it suitable for home use. However, traditional vacuum packaging machines have a significant problem when handling foods with juice: the juice is squeezed and overflows from the packaging bag, causing contamination of the vacuum packaging machine. This phenomenon not only affects the lifespan of the equipment but may also lead to secondary contamination of the food, reducing the preservation effect.

[0003] To address the aforementioned issues, Chinese utility model patent CN222876365U discloses a vacuum sealing machine, comprising a base, a groove, and a cover. The base has an internal cavity; the upper surface of the base is provided with a heat-sealing strip, a vacuum groove, an air hole, and a sealing gasket, with the vacuum groove located on one side of the heat-sealing strip; the sealing gasket is wrapped around the opening of the vacuum groove; the air hole is located between the inner wall of the sealing gasket and the wall of the vacuum groove, and the air hole communicates with the cavity; the groove is snapped into the vacuum groove, and a water-receiving groove is provided on the upper surface of the groove; one side of the cover is hinged to the side of the base away from the heat-sealing strip. In this technical solution, a water collection tank is used to collect the liquid extracted from the vacuum packaging bag, solving the problem of easy contamination when traditional vacuum packaging machines handle food packaging bags containing juice. However, when packaging food containing juice in batches, the water collection tank will quickly fill with liquid, which can easily overflow and dirty the packaging machine. It can even flow into the packaging machine through the air extraction port, causing short circuits and corrosion on the internal circuit boards, affecting the normal operation and service life of the equipment. Juice that is not cleaned in time can also cause the machine to produce odors, affecting the user experience. Therefore, users need to frequently disassemble the water collection tank and pour out the liquid. After cleaning, the water collection tank needs to be reinstalled and reset. Frequent operation is laborious and cumbersome, reducing the user experience. Summary of the Invention

[0004] The technical problem to be solved by this application is to provide a vacuum packaging machine that, by introducing a gas-liquid separation device, effectively solves the problems of traditional vacuum packaging machines being prone to equipment contamination and equipment damage caused by liquid entering the suction components when processing food packaging bags containing juice.

[0005] This application provides a vacuum packaging machine, including a housing, an air extraction component inside the housing, a vacuum chamber on the housing, and a gas-liquid separation device inside the housing. The vacuum chamber, the gas-liquid separation device, and the air extraction component are sequentially connected. The air extraction component is used to extract the gas-liquid mixture in the vacuum chamber, and the gas-liquid separation device is used to separate the extracted gas-liquid mixture to discharge the gas and collect the liquid.

[0006] In this technical solution, the housing is the main structure of the entire vacuum packaging machine, used to house components such as the suction assembly, vacuum chamber, and gas-liquid separation device. The vacuum chamber is used to accommodate the interface of the packaging bag to be vacuumed and to perform the vacuuming operation on the packaging bag. The suction assembly is responsible for extracting the gas-liquid mixture from the vacuum chamber to provide the necessary vacuum level. The gas-liquid separation device is used to separate the gas-liquid mixture extracted from the vacuum chamber. The separated gas is discharged through the suction assembly, and the separated liquid is collected in the gas-liquid separation device, effectively preventing liquid from entering the suction assembly, avoiding equipment damage caused by liquid ingress, extending the service life of the packaging machine, increasing liquid storage capacity through the gas-liquid separation device, reducing the frequency of user cleaning, improving packaging efficiency and user experience.

[0007] As an improvement, the gas-liquid separation device includes a wastewater tank and a top cover. The top cover is installed on the wastewater tank and is connected to the vacuum chamber and the suction assembly. In this technical solution, the wastewater tank is used to collect and store the liquid after gas-liquid separation. The top cover is installed on the wastewater tank and connects the vacuum chamber and the suction assembly to ensure that the gas-liquid mixture can smoothly enter the wastewater tank for gas-liquid separation and to discharge the separated gas. At the same time, it ensures the sealing of the wastewater tank to prevent liquid leakage and improves the stability and reliability of the equipment.

[0008] As an improvement, the top cover is equipped with a baffle plate, part of which is inserted into the wastewater tank. The baffle plate is used for gas-liquid separation of the extracted gas-liquid mixture. In this technical solution, a baffle plate is installed inside the top cover, with part of it inserted into the wastewater tank, for gas-liquid separation of the extracted gas-liquid mixture. During the extraction process, the baffle plate effectively blocks the liquid, making it easier for it to collect and fall into the wastewater tank, while ensuring rapid gas extraction, thereby achieving gas-liquid separation. The baffle plate's blocking effect reduces the risk of liquid entering the extraction assembly, avoiding equipment damage caused by liquid ingress and extending the equipment's service life.

[0009] As an improvement, the surface of the partition is provided with a hydrophobic coating. In this technical solution, by coating the surface of the partition with a hydrophobic coating, the adhesion of liquid on the partition surface is reduced, ensuring that the liquid forms water droplets on the partition surface and slides off quickly, reducing liquid residue on the partition surface, improving liquid collection efficiency, making it easier for the liquid to collect and fall into the sewage tank, and the hydrophobic coating has good wear resistance and corrosion resistance, ensuring stable performance during long-term use.

[0010] As an improvement, the bottom of the wastewater tank is provided with a drain outlet, which is detachably connected to a sealing component. In this technical solution, the drain outlet is used to directly discharge the liquid collected in the wastewater tank. The detachable sealing component facilitates regular cleaning of the wastewater tank by the user. The design of the drain outlet and the sealing component ensures that no liquid leakage occurs during normal operation, while also facilitating cleaning by the user when needed, ensuring the cleanliness and hygiene of the equipment, and reducing odors and bacterial growth caused by liquid accumulation. The detachable sealing component includes, but is not limited to, rubber plugs, threaded plugs, etc., and is simple to operate and reliable in use.

[0011] As an improvement, the wastewater tank and the shell are integrally formed, and the drain outlet is located on the bottom wall of the shell. In this technical solution, the wastewater tank and the shell are designed as a whole, which enhances the stability and sealing of the structure. The integrally formed structure reduces connection points and lowers the risk of liquid leakage. Designing the drain outlet on the bottom wall of the shell facilitates the user's operation of liquid discharge and cleaning. The user only needs to remove the sealing piece to directly discharge the liquid without removing the entire wastewater tank, thus improving cleaning efficiency and user experience.

[0012] As an improvement, the wastewater tank has a transparent or semi-transparent sidewall. In this technical solution, by designing a transparent or semi-transparent sidewall, users can intuitively observe the accumulation of liquid within the wastewater tank, facilitating timely cleaning, preventing liquid overflow, reducing maintenance costs, and ensuring that the transparent or semi-transparent material has good durability and corrosion resistance, such as polycarbonate (PC) or polymethyl methacrylate (PMMA), to maintain stable performance during long-term use.

[0013] As an improvement, the gas-liquid separation device is provided with a first gas port and a second gas port. The first gas port is used to connect to the vacuum chamber, and the second gas port is used to connect to the pumping assembly. In this technical solution, the design of the first and second gas ports allows the gas-liquid mixture to smoothly enter the gas-liquid separation device and discharges the separated gas, thereby improving the efficiency of gas-liquid separation.

[0014] As an improvement, the horizontal height of the first air inlet is lower than that of the second air inlet. In this technical solution, the first air inlet is lower than the second air inlet, allowing the liquid to settle naturally under gravity and be collected. This height difference design prevents liquid from flowing into the suction assembly, avoiding equipment damage caused by liquid ingress and extending the equipment's service life.

[0015] As an improvement, the extraction assembly includes an extraction motor and an extraction pipe, wherein the extraction pipe sequentially connects the vacuum chamber, the gas-liquid separation device, and the extraction motor. In this technical solution, the extraction motor provides power to drive the extraction process, drawing a gas-liquid mixture from the vacuum chamber. The vacuum chamber, the gas-liquid separation device, and the extraction motor are sequentially connected via the extraction pipe, allowing the gas-liquid mixture in the vacuum chamber to flow smoothly to the gas-liquid separation device for gas-liquid separation. The separated gas can then smoothly enter the extraction motor and be discharged, improving the operational stability and reliability of the equipment. Attached Figure Description

[0025] like Figures 1 to 4As shown, this application discloses a vacuum packaging machine, including a housing 1, an air extraction assembly 2 inside the housing 1, a vacuum chamber 11 on the housing 1, and a gas-liquid separation device 3 inside the housing 1. The vacuum chamber 11, the gas-liquid separation device 3, and the air extraction assembly 2 are sequentially connected. The air extraction assembly 2 is used to extract the gas-liquid mixture in the vacuum chamber 11, and the gas-liquid separation device 3 is used to separate the extracted gas-liquid mixture to allow the gas to be discharged and the liquid to be collected. The housing 1 is the main structure of the entire vacuum packaging machine, used to house the air extraction assembly 2, the vacuum chamber 11, and the gas-liquid separation device 3, etc. The vacuum chamber 11 is used to house... The interface of the packaging bag to be vacuumed is connected, and the packaging bag is vacuumed. The vacuum assembly 2 is responsible for extracting the gas-liquid mixture from the vacuum chamber 11 to provide the necessary vacuum degree. The gas-liquid separation device 3 is used to separate the gas-liquid mixture extracted from the vacuum chamber 11. The separated gas is discharged through the vacuum assembly 2, and the separated liquid is collected in the gas-liquid separation device 3, which effectively prevents liquid from entering the vacuum assembly 2, avoids equipment damage caused by liquid entry, extends the service life of the packaging machine, increases the liquid storage capacity through the gas-liquid separation device 3, reduces the frequency of user cleaning, and improves packaging efficiency and user experience.

[0026] More specifically, such as Figures 2 to 4 As shown, the gas-liquid separation device 3 includes a wastewater tank 31 and a top cover 32. The top cover 32 is installed on the wastewater tank 31 and is connected to the vacuum chamber 11 and the air extraction component 2. The wastewater tank 31 is used to collect and store the liquid after gas-liquid separation. The top cover 32 is installed on the wastewater tank 31 and connects the vacuum chamber 11 and the air extraction component 2 to ensure that the gas-liquid mixture can smoothly enter the wastewater tank 31 for gas-liquid separation and discharge the separated gas. At the same time, it ensures the sealing of the wastewater tank 31 to prevent liquid leakage and improve the stability and reliability of the equipment.

[0027] More specifically, such as Figures 2 to 4 As shown, the top cover 32 is provided with a partition 33, which is partially inserted into the sewage tank 31. The partition 33 is used to separate the extracted gas-liquid mixture. During the gas extraction process, the partition 33 can effectively block the liquid, making it easier for it to gather and fall into the sewage tank 31, while ensuring that the gas is extracted quickly, thereby achieving gas-liquid separation. Through the blocking effect of the partition 33, the risk of liquid entering the gas extraction component 2 is reduced, avoiding equipment damage caused by liquid entry and extending the service life of the equipment.

[0028] More specifically, the surface of the partition 33 is provided with a hydrophobic coating. By applying a hydrophobic coating to the surface of the partition 33, the adhesion of liquid to the surface of the partition 33 is reduced, ensuring that the liquid forms water droplets on the surface of the partition 33 and slides off quickly, reducing the residue of liquid on the surface of the partition 33, improving the liquid collection efficiency, making it easier for the liquid to collect and fall into the sewage tank 31, and the hydrophobic coating has good wear resistance and corrosion resistance, ensuring that the performance remains stable during long-term use.

[0029] More specifically, such as Figure 4 As shown, the bottom of the sewage tank 31 is provided with a drain outlet 311, and the drain outlet 311 is detachably connected to a sealing component 34. The drain outlet 311 is used to directly discharge the liquid collected in the sewage tank 31. The detachable sealing component 34 makes it convenient for users to clean the sewage tank 31 regularly. The design of the drain outlet 311 and the sealing component 34 ensures that there will be no leakage of liquid during normal operation, and at the same time, it is convenient for users to clean when needed, ensuring the cleanliness and hygiene of the equipment, reducing odor and bacterial growth caused by liquid accumulation. The detachable sealing component 34 includes, but is not limited to, rubber plugs, threaded plugs, etc., which are simple to operate and reliable to use.

[0030] More specifically, such as Figure 3 and Figure 4 As shown, the sewage tank 31 and the shell 1 are integrally formed. The drain outlet 311 is located on the bottom wall of the shell 1. The design of the sewage tank 31 and the shell 1 as a whole enhances the stability and sealing of the structure. The integrally formed structure reduces the number of connection points and reduces the risk of liquid leakage. The drain outlet 311 is designed on the bottom wall of the shell 1, which makes it convenient for users to operate the liquid discharge and cleaning. Users only need to remove the sealing part 34 to directly discharge the liquid without removing the entire sewage tank 31, which improves cleaning efficiency and user experience.

[0031] More specifically, the sewage tank 31 has a transparent or semi-transparent sidewall. By designing a transparent or semi-transparent sidewall, users can intuitively observe the accumulation of liquid in the sewage tank 31, which is convenient for timely cleaning, avoids liquid overflow, and reduces maintenance costs. Furthermore, the transparent or semi-transparent material should have good durability and corrosion resistance, such as polycarbonate (PC) and polymethyl methacrylate (PMMA), to ensure stable performance during long-term use.

[0032] More specifically, such as Figure 4 As shown, the gas-liquid separation device 3 is provided with a first gas port 35 and a second gas port 36. The first gas port 35 is used to connect to the vacuum chamber 11, and the second gas port 36 is used to connect to the pumping assembly 2. Through the design of the first gas port 35 and the second gas port 36, the gas-liquid mixture can smoothly enter the gas-liquid separation device 3 and discharge the separated gas, thereby improving the efficiency of gas-liquid separation.

[0033] More specifically, such as Figure 4As shown, the horizontal height of the first air port 35 is lower than that of the second air port 36. The liquid can settle naturally under the action of gravity and be collected. Through the height difference design, liquid is prevented from flowing into the air extraction component 2, avoiding equipment damage caused by liquid entry and extending the service life of the equipment.

[0034] More specifically, such as Figure 2 and Figure 3 As shown, the vacuum assembly 2 includes a vacuum motor 21 and a vacuum pipe 22. The vacuum pipe 22 is used to connect the vacuum chamber 11, the gas-liquid separator 3 and the vacuum motor 21 in sequence. The vacuum motor 21 provides power to drive the vacuum process and extract the gas-liquid mixture from the vacuum chamber 11. The vacuum chamber 11, the gas-liquid separator 3 and the vacuum motor 21 are connected in sequence through the vacuum pipe 22. The gas-liquid mixture in the vacuum chamber 11 can flow smoothly to the gas-liquid separator 3 for gas-liquid separation. The separated gas can smoothly enter the vacuum motor 21 and be discharged, improving the operational stability and reliability of the equipment.

[0035] This application is not limited to the above-described preferred embodiments. Anyone can derive other products in various forms under the guidance of this application. However, regardless of any changes made to their shape or structure, any technical solution that is the same as or similar to that of this application falls within the protection scope of this application.
