Description

Technical Field

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

[0002] With the improvement of people's living standards, sealing machines have gradually appeared in households. In related technology, a sealing machine includes a housing, an annular seal, and a heating element. The housing and the annular seal enclose a vacuum chamber. The heating element is positioned far from the annular seal and the vacuum chamber; this distance from the heating element and the opening of the bag to be sealed results in slow heat transfer and poor sealing effect. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, this application proposes a sealing machine.

[0005] In view of this, this application provides a sealing machine, comprising: a first cover having a first sealing chamber; a first sealing ring disposed within and surrounding the first sealing chamber; a second cover being closably connected to the first cover, the second cover having a second sealing chamber; a second sealing ring disposed within and surrounding the second sealing chamber, wherein when the first cover and the second cover are in a closed state, the first sealing chamber, the first sealing ring, the second sealing chamber, and the second sealing ring enclose a vacuum chamber; and a heating element connected to one of the first sealing ring and the first cover, wherein when the heating element is connected to the first cover and the first cover and the second cover are in a closed state, at least a portion of the heating element is located within the vacuum chamber.

[0006] The sealing machine provided in this application includes a first cover, a first sealing ring, a second cover, a heating element, and a second sealing ring.

[0007] The first cover has a first sealing chamber, and the second cover has a second sealing chamber.

[0008] The first sealing ring is located in the first sealing chamber, that is, the first sealing chamber serves as the mounting carrier for the first sealing ring and has the function of installing and fixing the first sealing ring.

[0009] The second sealing ring is located in the second sealing chamber. That is, the second sealing chamber serves as the mounting carrier for the second sealing ring and has the function of installing and fixing the second sealing ring.

[0010] The heating element is connected to either the first sealing ring or the first cover. That is, the heating element is connected to the first sealing ring, or the heating element is connected to the first cover.

[0011] When the heating element is connected to the first sealing ring, the first sealing ring serves as the mounting carrier for the heating element, functioning to install and secure it. The first sealing ring surrounds the first sealing chamber; that is, the heating element is installed within the first sealing chamber via the first sealing ring. The first cover body does not require a separate structure for installing and securing the heating element. This simplifies the structural complexity of the first cover body, facilitates the installation of the sealing machine, improves the assembly efficiency of the sealing machine, and reduces its production costs. Simultaneously, because the heating element is connected to the first sealing ring, the distance between the heating element and the first sealing ring can be reduced, decreasing the thickness of the structure between the heating element and the bag to be sealed. This allows the heat generated by the heating element to be effectively and promptly transferred to the bag, accelerating the heat transfer speed of the heating element, reducing heat loss, and ensuring the effectiveness and feasibility of sealing while reducing the energy consumption of the sealing machine. Furthermore, this design reduces the space occupied by the heating element on the first cover, allowing for a relative increase in the volume of the vacuum chamber. The vacuum chamber can be closer to the user, making it easier for the user to insert the bag into the vacuum chamber without causing vacuum failure. Unlike sealing machines in related technologies, where the user needs to insert the bag to the rear of the vacuum chamber to confirm placement, in this application, the vacuum chamber is closer to the front. This ensures that even if the bag is only partially inserted into the sealing area, vacuuming can still be completed effectively, improving the user experience. Additionally, when the heating element and vacuum chamber are separate, users may easily place the bag on the heating element without actually inserting it into the vacuum chamber, resulting in incomplete vacuuming. In this application, by placing the first sealing ring and the heating element together, the problem of vacuum failure is avoided when the user places the bag.

[0012] When the heating element is connected to the first cover and both the first and second covers are closed, at least a portion of the heating element is located within the vacuum chamber. Compared to related technologies where the heating element is located further away from the annular seal and vacuum chamber, this arrangement reduces the space occupied by the heating element on the first cover while maintaining the same overall dimensions of the sealing machine. This allows for a relative increase in the volume of the vacuum chamber, which can be positioned closer to the user. This makes it easier for the user to insert the bag into the vacuum chamber without causing vacuum failure. Furthermore, unlike related technologies where the bag needs to be inserted to the rear of the vacuum chamber to confirm its placement, in this application, the vacuum chamber is closer to the front. This ensures that even if the bag is only partially inserted into the sealing area, vacuuming can still be completed effectively, improving the user experience. Additionally, when the heating element and vacuum chamber are separate, the user may easily place the bag only on the heating element without actually inserting it into the vacuum chamber, resulting in incomplete vacuuming. In this application, the first cover and the heating element are arranged together, and when the first and second covers are in the closed state, at least a portion of the heating element is located within the vacuum chamber. This avoids the problem of vacuum failure when the user places the bag. Simultaneously, this structure reduces the distance between the heating element and the vacuum chamber, allowing the heat generated by the heating element to be effectively and promptly transferred to the bag to be sealed, accelerating the heat transfer speed of the heating element, reducing heat loss, and ensuring the effectiveness and feasibility of sealing while helping to reduce the energy consumption of the sealing machine.

[0013] When vacuuming the bag, first place the bag opening into the first or second sealing chamber, then close the first or second cover, so that the first and second covers are in the closed state. The first sealing chamber, the first sealing ring, the second sealing chamber, and the second sealing ring enclose a vacuum chamber. At this time, the air inlet of the sealing machine is blocked, and ambient air cannot enter the vacuum chamber through the air inlet. Vacuuming the vacuum chamber causes the first and second sealing chambers to be drawn together by air pressure, and the first and second sealing rings seal accordingly, pressing the bag opening tightly. The heat generated by the heating element melts or softens the bag, thus achieving a seal. After the vacuuming operation is complete, open the air inlet, and air will flow into the vacuum chamber through the air inlet. The vacuum chamber is no longer in a sealed vacuum state, and the first and second sealing chambers are no longer affected by the pressure difference, separating and detaching to complete the opening operation of the sealing machine.

[0014] In some technical solutions, optionally, when the heating element is connected to the first sealing ring, the first sealing ring covers at least a portion of the heating element.

[0015] In this technical solution, the mating structure of the first sealing ring and the heating element is defined.

[0016] When the heating element is connected to the first sealing ring, the first sealing ring covers at least a portion of the heating element. That is, the first sealing ring covers a portion of the heating element. Alternatively, the first sealing ring completely covers the heating element.

[0017] When the first sealing ring covers a portion of the heating element, that is, a portion of the heating element is located inside the first sealing ring while the other portion is exposed. Having a portion of the heating element inside the first sealing ring ensures the mating area between the first sealing ring and the heating element, guaranteeing the effectiveness and reliability of the assembly. Having the other portion of the heating element exposed means that it is not obstructed by the first sealing ring, facilitating heat dissipation and temperature measurement.

[0018] When the first sealing ring completely covers the heating element, that is, the heating element is entirely located within the first sealing ring, the heat generated by the heating element can be transferred to the bag to be sealed in a timely manner. This helps to accelerate the heat transfer speed of the heating element, reduce heat loss, and while ensuring the effectiveness and feasibility of sealing, it also helps to further reduce the energy consumption of the sealing machine.

[0019] In some technical solutions, optionally, the heating component includes: a bracket, at least a portion of which is located within a first sealing ring; an insulating member disposed on the portion of the bracket located within the first sealing ring; and a heating element disposed on the insulating member, with the heating element located between the first sealing ring and the insulating member.

[0020] In this technical solution, the heating component includes a bracket, an insulating component, and a heating element.

[0021] At least a portion of the bracket is located within the first sealing ring, the insulating element is disposed on the portion of the bracket located within the first sealing ring, and the heating element is disposed on the insulating element. That is, the bracket serves to support and fix the insulating element and the heating element to ensure the fit dimensions between the heating element and the vacuum chamber.

[0022] Understandably, the heating element is located between the first sealing ring and the insulating component. This arrangement shortens the distance between the heating element and the vacuum chamber, allowing the heat generated by the heating element to be effectively and promptly transferred to the bag to be sealed, accelerating the heat transfer rate and reducing heat loss. Furthermore, the structural design of the insulating component ensures the safety and reliability of the heating element's operation, enabling the sealing machine to meet safety regulations. Simultaneously, it prevents issues such as product leakage, air leakage, and water ingress, providing structural support for ensuring the safety and reliability of the product.

[0023] It is understandable that when the first sealing ring covers a portion of the heating element, part of the bracket is located inside the first sealing ring, and the other part of the bracket is located outside the first sealing ring, while both the insulating component and the heating element are located inside the first sealing ring. This arrangement ensures the effectiveness and reliability of the assembly between the heating element and the first sealing ring, while also increasing the exposed area of ​​the heating element and improving the timeliness and effectiveness of heat dissipation.

[0024] Understandably, when the first sealing ring completely covers the heating element, the bracket, insulation component, and heating element are all located within the first sealing ring. The first sealing ring can cover the heating element from all directions and angles, enhancing the stability of the assembled heating element and preventing it from falling off. Simultaneously, it prevents issues such as electrical leakage, air leakage, and water ingress, providing structural support to ensure the safety and reliability of the product.

[0025] In some technical solutions, optionally, the bracket is provided with a first slot, and at least a portion of the insulating element is located in the first slot; and / or the first sealing ring is provided with a second slot, and at least a portion of the bracket is located in the second slot, with the heating element abutting against the bottom wall of the second slot.

[0026] In this technical solution, when the bracket has a first slot, at least a portion of the insulating component is located within the first slot. This arrangement increases the mating area between the bracket and the insulating component, and the slot wall of the first slot serves to limit the insulating component, ensuring the stability and reliability of the assembly of the insulating component, bracket, and heating element. Simultaneously, this structural arrangement also helps to reduce the overall size of the heating component, decrease the occupancy rate of the sealing machine's internal space, and provide effective structural support for increasing the volume of the vacuum chamber.

[0027] When the first sealing ring has a second groove, at least a portion of the bracket is located within the second groove, and the heating element abuts against the bottom wall of the second groove. This arrangement shortens the distance between the heating element and the vacuum chamber, allowing the heat generated by the heating element to be effectively and promptly transferred to the bag to be sealed. Simultaneously, this structural design ensures the mating area between the bracket and the first sealing ring, and the groove wall of the second groove acts as a limiting bracket, ensuring the stability and reliability of the assembly of the insulating component, bracket, and heating element.

[0028] In some technical solutions, optionally, when the first sealing ring is provided with a second groove, the distance from the bottom wall of the second groove to the side end face of the first sealing ring facing the second sealing ring is greater than or equal to 0.5 mm and less than or equal to 2 mm.

[0029] In this technical solution, the mating structure between the heating element and the first sealing ring is further defined.

[0030] When the first sealing ring has a second groove, and the first and second covers are in the closed state, the distance from the bottom wall of the second groove to the side of the first sealing ring facing the second sealing ring is greater than or equal to 0.5 mm and less than or equal to 2 mm. This setting ensures that the heat generated by the heating element can effectively melt or soften the bag, while also ensuring the safety and reliability of the sealing machine.

[0031] If the distance from the bottom wall of the second slot to the end face of the first sealing ring facing the second sealing ring is less than 0.5mm, then the distance from the bottom wall of the second slot to the end face of the first sealing ring facing the second sealing ring is relatively short. In other words, when the first and second covers are closed, the portion of the first sealing ring between the second sealing ring and the heating element is thinner. This portion is more susceptible to damage under the heating effect of the heating element, potentially leading to problems such as electrical leakage, air leakage, and water ingress, thus reducing the product's performance and market competitiveness.

[0032] If the distance from the bottom wall of the second slot to the side of the first sealing ring facing the second sealing ring is greater than 2mm, then the distance from the bottom wall of the second slot to the side of the first sealing ring facing the second sealing ring is relatively large. In other words, when the first and second covers are in the closed state, the portion of the first sealing ring between the second sealing ring and the heating element is thicker, resulting in slower heat transfer, poor sealing performance, and reduced product performance and market competitiveness.

[0033] In some technical solutions, optionally, when the first sealing ring is provided with a second groove, the distance from the groove sidewall of the second groove to the outer peripheral wall of the first sealing ring is greater than or equal to 10mm.

[0034] In this technical solution, the mating structure between the heating element and the first sealing ring is further defined.

[0035] When the first sealing ring is provided with a second slot, the distance from the side wall of the second slot to the outer peripheral wall of the first sealing ring is greater than or equal to 10mm. The first sealing ring includes heating components on both sides. This setting limits the wrapping length of the first sealing ring, which can ensure the stability and reliability of the assembly between the first sealing ring and the heating component, as well as the area of ​​the heating component for temperature measurement and external heat dissipation.

[0036] In some technical solutions, optionally, when the first cover and the second cover are in the closed state and the first sealing ring covers a part of the heating component, the heating component has a first end and a second end opposite to each other along the direction from the second cover to the first cover. The first end is located inside the first sealing ring, and the second end is exposed outside the first sealing ring. The second end is located between the second sealing ring and the end of the first sealing ring that is away from the second sealing ring.

[0037] In this technical solution, the mating structure of the first sealing ring, the second sealing ring, and the heating element is further defined.

[0038] When the first cover and the second cover are in the closed state, and the first sealing ring covers a portion of the heating element, the heating element has a first end and a second end opposite to each other, arranged along the direction from the second cover to the first cover. The first end is closer to the second sealing ring than the second end. The first end is located inside the first sealing ring, and the second end is exposed outside the first sealing ring, and the second end is located between the second sealing ring and the end of the first sealing ring facing away from the second sealing ring.

[0039] Therefore, the first sealing ring can elevate the heating component, separating it from other components in the sealing machine. This spacing prevents the heating component from contacting other components and causing damage to them.

[0040] In some technical solutions, optionally, a portion of the second sealing ring forms a pressure strip, which abuts against the first sealing ring when the first cover and the second cover are in the closed state.

[0041] In this technical solution, the structure of the second sealing ring is further defined.

[0042] A portion of the second sealing ring forms a pressure strip.

[0043] The second sealing ring is arranged around the second sealing chamber.

[0044] When the first and second covers are closed, the second sealing ring abuts against the first sealing ring; specifically, the pressure strip abuts against the first sealing ring. After the vacuum chamber is evacuated, the first and second sealing rings are tightly attracted together, causing the first sealing ring and the pressure strip to abut against each other, effectively sealing the connection between the first and second sealing chambers and preventing air leakage. The pressure strip, under pressure, cooperates with the first sealing ring to tightly press the bag opening, ensuring uniform force distribution in the vent area and preventing partial unsealing or leaks at the bag opening.

[0045] A portion of the second sealing ring forms a pressure strip. This feature ensures the effectiveness and feasibility of the seal between the first and second sealing rings while simplifying the internal assembly structure of the sealing machine and reducing the difficulty of operation for users. Therefore, the second sealing ring not only seals the vacuum chamber but also presses down on the bag opening, enriching its functionality and improving the product's performance.

[0046] In some technical solutions, the second sealing ring may optionally include: two strip segments arranged opposite to each other and spaced apart along a first direction, one strip segment forming a pressure strip; and two connecting segments, each connecting segment connecting between the two strip segments, and the two connecting segments arranged spaced apart along a second direction; wherein the length of the strip segment in the second direction is greater than the length of the connecting segment in the first direction.

[0047] In this technical solution, the structure of the second sealing ring is further defined.

[0048] The second sealing ring consists of two strip segments and two connecting segments.

[0049] Two strip segments are arranged opposite each other and spaced apart along a first direction. Each connecting segment connects the two strip segments, and the two connecting segments are arranged spaced apart along a second direction. The two strip segments and the two connecting segments form a runway-shaped structure.

[0050] Specifically, a strip segment forms a pressure strip, which satisfies the requirement that a portion of the second sealing ring forms a pressure strip.

[0051] In addition, the longer strip segments form a sealing strip, which helps to extend the length of the sealing strip and the heating element, enabling sealing operations for larger bags as well as smaller bags, thus providing structural support to ensure the performance of the sealing machine.

[0052] In some technical solutions, optionally, the second sealing ring includes: a sealing ring body, the length of the sealing ring body in the first direction being less than the length of the sealing ring body in the second direction; a pressure strip disposed on the sealing ring body, at least a portion of the pressure strip protruding from the sealing ring body along the first direction, and the pressure strip extending along the second direction.

[0053] In this technical solution, the structure of the second sealing ring is further defined.

[0054] The second sealing ring includes a sealing ring body and a pressure strip. The length of the sealing ring body in the first direction is less than the length of the sealing ring body in the second direction; that is, the sealing ring body has a racetrack-shaped structure.

[0055] The sealing ring is arranged around the second sealing chamber.

[0056] A pressure strip is disposed on the sealing ring body. At least a portion of the pressure strip protrudes from the sealing ring body along a first direction, and extends along a second direction. When the first and second covers are closed, the pressure strip abuts against the first sealing ring. Specifically, after the vacuum chamber is evacuated, the first and second sealing rings are tightly attracted together, causing the first sealing ring and the pressure strip to abut against each other, effectively sealing the connection between the first and second sealing chambers and preventing air leakage. The pressure strip, under pressure, cooperates with the first sealing ring to tightly press the bag opening, ensuring uniform force distribution in the vent area and preventing partial unsealing or leaks at the bag opening.

[0057] The pressure strip is located on the sealing ring body. This feature ensures the effectiveness and feasibility of sealing the first and second sealing rings while simplifying the internal assembly structure of the sealing machine and reducing the difficulty of operation for users.

[0058] In addition, the pressure strip extends along the second direction. This arrangement helps to extend the length of the pressure strip and the heating element, enabling sealing operations for larger bags as well as smaller bags, thus providing structural support to ensure the performance of the sealing machine.

[0059] When the first cover and the second cover are in the closed state, the sealing ring and the pressure strip are both in contact with the first sealing ring.

[0060] In some technical solutions, optionally, when the first cover and the second cover are in the closed state, the pressure strip is positioned opposite to the heating element.

[0061] In this technical solution, the mating structure of the pressure strip and the heating element is further defined. When the first and second covers are in the closed state, the pressure strip and the heating element are positioned opposite each other. That is, the positional relationship between the pressure strip and the heating element is defined. The pressure strip can tightly press the bag opening onto the heating element, causing the bag opening to melt and seal upon heating, ensuring the flatness and strength of the bag opening seal. Because the pressure strip and the heating element are positioned opposite each other, the mating position of the bag opening pressed by the pressure strip and the heating element can be guaranteed, allowing the bag opening to be aligned with the heating element, providing structural support for ensuring the effectiveness and feasibility of the sealing.

[0062] In some technical solutions, optionally, the first cover and the second cover are rotatably connected, and the pressure strip is located on the side of the second sealing chamber away from the rotatable connection between the first cover and the second cover.

[0063] In this technical solution, the cooperative structure of the pressure strip, the second sealing chamber, the first cover and the second cover is further defined.

[0064] The first cover and the second cover are rotatably connected, and one of the first cover and the second cover can rotate relative to the other to meet the usage requirements of the first cover and the second cover being openable and closable.

[0065] The pressure strip is located on the side of the second sealing chamber away from the rotating connection between the first and second covers. When the first and second covers are closed, the pressure strip and the heating element are positioned opposite each other; therefore, the heating element is located on the side of the second sealing chamber away from the rotating connection between the first and second covers. Thus, both the pressure strip and the heating element are close to the openings of the first and second covers, reducing the distance between either the pressure strip or the heating element and the openings of the first and second covers. This reduces the area of ​​the bag extending into the vacuum chamber during vacuuming, enabling effective vacuuming and sealing of bags of various sizes. For example, it can effectively vacuum and seal small bags as well as large bags, improving the adaptability of the sealing machine and enhancing its performance and market competitiveness.

Detailed Implementation

[0077] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0078] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0079] The following reference Figures 1 to 7 The sealing machine 10 of some embodiments of this application is described.

[0080] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, according to some embodiments of this application, a sealing machine 10 is proposed, comprising: a first cover 100 having a first sealing chamber 110; a first sealing ring 210 disposed within and surrounding the first sealing chamber 110; a second cover 300 openably connected to the first cover 100, the second cover 300 having a second sealing chamber 310; and a second sealing ring 400 disposed within and surrounding the second sealing chamber 310. When the first cover... When the body 100 and the second cover 300 are in the closed state, the first sealing chamber 110, the first sealing ring 210, the second sealing chamber 310 and the second sealing ring 400 enclose a vacuum cavity 500; the heating component 220 is connected to one of the first sealing ring 210 and the first cover 100. When the heating component 220 is connected to the first cover 100 and the first cover 100 and the second cover 300 are in the closed state, at least a portion of the heating component 220 is located inside the vacuum cavity 500.

[0081] The sealing machine 10 provided in this application includes a first cover 100, a first sealing ring 210, a second cover 300, a heating element 220, and a second sealing ring 400.

[0082] The first cover 100 has a first sealing chamber 110, and the second cover 300 has a second sealing chamber 310.

[0083] The first sealing ring 210 is disposed in the first sealing chamber 110. That is, the first sealing chamber 110 serves as the mounting carrier for the first sealing ring 210 and has the function of installing and fixing the first sealing ring 210.

[0084] The second sealing ring 400 is disposed in the second sealing chamber 310. That is, the second sealing chamber 310 serves as the mounting carrier for the second sealing ring 400 and has the function of installing and fixing the second sealing ring 400.

[0085] The heating element 220 is connected to either the first sealing ring 210 or the first cover 100. That is, the heating element 220 is connected to the first sealing ring 210 or the heating element 220 is connected to the first cover 100.

[0086] When the heating element 220 is connected to the first sealing ring 210, the first sealing ring 210 serves as the mounting carrier for the heating element 220, and has the function of installing and fixing the heating element 220. The first sealing ring 210 is arranged around the first sealing chamber 110, that is, the heating element 220 is installed in the first sealing chamber 110 through the first sealing ring 210. There is no need to separately set up a structure for installing and fixing the heating element 220 inside the first cover 100. This simplifies the structural complexity of the first cover 100, facilitates the installation of the sealing machine 10, improves the assembly efficiency of the sealing machine 10, and helps reduce the production cost of the sealing machine 10. Meanwhile, since the heating element 220 is connected to the first sealing ring 210, the distance between the heating element 220 and the first sealing ring 210 can be reduced. This reduces the thickness of the structure of the sealing machine 10 located between the heating element 220 and the bag to be sealed, allowing the heat generated by the heating element 220 to be effectively and promptly transferred to the bag to be sealed. This accelerates the heat transfer speed of the heating element 220 and reduces heat loss. While ensuring the effectiveness and feasibility of sealing, it also helps to reduce the energy consumption of the sealing machine 10. In addition, this design can reduce the space occupied by the heating element 220 on the first cover 100, which can relatively increase the volume of the vacuum chamber 500. The vacuum chamber 500 can be closer to the user side, making it easier for the user to insert the bag into the vacuum chamber 500 without causing vacuum failure. Furthermore, unlike sealing machines in related technologies, where users don't need to insert the bag into the rear of the vacuum chamber to confirm its placement, in this application, the vacuum chamber 500 is closer to the front. This allows for efficient vacuuming even if the bag is only partially inserted into the sealing area, improving the user experience. Additionally, when the heating element 220 and vacuum chamber 500 are separate, users may easily place the bag only on the heating element 220 without actually inserting it into the vacuum chamber 500, resulting in incomplete vacuuming. In this application, the first sealing ring 210 and heating element 220 are placed together, preventing vacuuming failure when placing the bag.

[0087] When the heating element 220 is connected to the first cover 100 and the first cover 100 and the second cover 300 are in the closed state, at least a portion of the heating element 220 is located within the vacuum chamber 500. Compared to the arrangement of the vacuum chamber in related technologies, which is far from the annular seal, this arrangement reduces the space occupied by the heating element 220 on the first cover 100 while keeping the overall dimensions of the sealing machine 10 unchanged. This allows for a relative increase in the volume of the vacuum chamber 500, which can be closer to the user side. When placing a bag, the user can more easily insert the bag into the vacuum chamber 500 without causing vacuum failure. Furthermore, unlike sealing machines in related technologies, the user does not need to insert the bag to the rear of the vacuum chamber to confirm that the bag is in the vacuum chamber. In this application, the vacuum chamber 500 is closer to the front, so even if the bag is inserted only a short distance into the sealing area, the vacuum operation can be completed effectively, improving the user experience. Furthermore, when the heating element 220 and the vacuum chamber 500 are set separately, users may easily place the bag only on the heating element 220 without actually inserting it into the vacuum chamber 500, resulting in incomplete vacuuming. In this application, the first cover 100 and the heating element 220 are set together, and when the first cover 100 and the second cover 300 are in the closed state, at least a portion of the heating element 220 is located inside the vacuum chamber 500. This avoids the problem of vacuuming failure when the user places the bag. At the same time, this structure reduces the distance between the heating element 220 and the vacuum chamber 500, allowing the heat generated by the heating element 220 to be effectively and promptly transferred to the bag to be sealed, accelerating the heat transfer speed of the heating element 220, reducing heat loss, and helping to reduce the energy consumption of the sealing machine 10 while ensuring the effectiveness and feasibility of sealing.

[0088] When vacuuming the bag, first place the bag opening in the first sealing chamber 110 or the second sealing chamber 310, then close the first cover 100 or the second cover 300, so that the first cover 100 and the second cover 300 are in the closed state. The first sealing chamber 110, the first sealing ring 210, the second sealing chamber 310, and the second sealing ring 400 enclose the vacuum chamber 500. At this time, the air inlet of the sealing machine 10 is blocked, and air in the environment cannot enter the vacuum chamber 500 through the air inlet. Vacuuming the vacuum chamber 500 causes the first sealing chamber 110 and the second sealing chamber 310 to be sucked together by air pressure, and the first sealing ring 210 and the second sealing ring 400 seal accordingly to compress the bag opening. The heat generated by the heating element 220 can melt or soften the bag, thereby achieving a seal. After the vacuuming operation is completed, the air inlet is opened, and air will flow into the vacuum chamber 500 through the air inlet. The vacuum chamber 500 is no longer in a sealed vacuum state, and the first sealing chamber 110 and the second sealing chamber 310 are no longer affected by the pressure difference. The first sealing chamber 110 and the second sealing chamber 310 separate and fall off to complete the opening operation of the sealing machine 10.

[0089] For example, when the first cover 100 and the second cover 300 are in the closed state, the first sealing ring 210 and the second sealing ring 400 are located at the connection between the first sealing chamber 110 and the second sealing chamber 310, and the first sealing ring 210 and the second sealing ring 400 abut against each other. After the vacuum chamber 500 is evacuated, the first sealing ring 210 and the second sealing ring 400 are tightly attracted together to effectively seal the connection between the first sealing chamber 110 and the second sealing chamber 310 and prevent air leakage.

[0090] For example, when the first cover 100 and the second cover 300 are in the closed state, the first sealing ring 210 and the second sealing ring 400 are fitted together to seal. After the vacuum chamber 500 is evacuated, the first sealing ring 210 and the second sealing ring 400 are tightly attracted together to effectively seal the connection between the first sealing chamber 110 and the second sealing chamber 310 and prevent air leakage.

[0091] For example, when the first cover 100 and the second cover 300 are in the closed state, the first cover 100 is located above the second cover 300. Alternatively, when the first cover 100 and the second cover 300 are in the closed state, the second cover 300 is located above the first cover 100.

[0092] In some embodiments, for example, when the heating component 220 is connected to the first sealing ring 210, the first sealing ring 210 covers at least a portion of the heating component 220.

[0093] In this embodiment, the mating structure of the first sealing ring 210 and the heating element 220 is defined.

[0094] When the heating element 220 is connected to the first sealing ring 210, the first sealing ring 210 covers at least a portion of the heating element 220. That is, the first sealing ring 210 covers a portion of the heating element 220. Alternatively, the first sealing ring 210 completely covers the heating element 220.

[0095] When the first sealing ring 210 covers a portion of the heating element 220, that is, a portion of the heating element 220 is located within the first sealing ring 210, while the other portion of the heating element 220 is exposed outside the first sealing ring 210. Having a portion of the heating element 220 within the first sealing ring 210 ensures the mating area between the first sealing ring 210 and the heating element 220, guaranteeing the effectiveness and reliability of the assembly between the heating element 220 and the first sealing ring 210. Having the other portion of the heating element 220 exposed outside the first sealing ring 210 means that the other portion of the heating element 220 is not obstructed by the first sealing ring 210, thus facilitating heat dissipation and temperature measurement by the heating element 220.

[0096] When the first sealing ring 210 completely covers the heating element 220, that is, the heating element 220 is completely located inside the first sealing ring 210, the heat generated by the heating element 220 can be transferred to the bag to be sealed in a timely manner, which helps to accelerate the heat transfer speed of the heating element 220 and reduce heat loss. While ensuring the effectiveness and feasibility of sealing, it also helps to further reduce the energy consumption of the sealing machine 10.

[0097] In some embodiments, exemplarily, such as Figure 3 , Figure 4 and Figure 5 As shown, the heating component 220 includes: a bracket 222, at least a portion of which is located within the first sealing ring 210; an insulating member 224 disposed on the portion of the bracket 222 located within the first sealing ring 210; and a heating member 226 disposed on the insulating member 224, with the heating member 226 located between the first sealing ring 210 and the insulating member 224.

[0098] In this embodiment, the heating component 220 includes a bracket 222, an insulator 224, and a heating element 226.

[0099] At least a portion of the bracket 222 is located within the first sealing ring 210, the insulating element 224 is disposed on the portion of the bracket 222 located within the first sealing ring 210, and the heating element 226 is disposed on the insulating element 224. That is, the bracket 222 has the function of supporting and fixing the insulating element 224 and the heating element 226 to ensure the fitting dimensions of the heating element 226 and the vacuum cavity 500.

[0100] Understandably, the heating element 226 is located between the first sealing ring 210 and the insulating element 224. This arrangement shortens the distance between the heating element 226 and the vacuum chamber 500, allowing the heat generated by the heating element 226 to be effectively and promptly transferred to the bag to be sealed, thus accelerating the heat transfer speed of the heating element 226 and reducing heat loss. Furthermore, the structural design of the insulating element 224 ensures the safety and reliability of the heating assembly 220, enabling the sealing machine 10 to meet safety regulations. Simultaneously, it prevents problems such as product leakage, air leakage, and water ingress, providing structural support for ensuring the safety and reliability of product use.

[0101] It is understandable that when the first sealing ring 210 covers a portion of the heating element 220, a portion of the bracket 222 is located inside the first sealing ring 210, and the other portion of the bracket 222 is located outside the first sealing ring 210. Both the insulating component 224 and the heating element 226 are located inside the first sealing ring 210. This arrangement ensures the effectiveness and reliability of the assembly between the heating element 220 and the first sealing ring 210, while also increasing the exposed area of ​​the heating element 220 and improving the timeliness and effectiveness of heat dissipation from the heating element 220.

[0102] Understandably, when the first sealing ring 210 completely covers the heating element 220, the bracket 222, the insulator 224, and the heating element 226 are all located within the first sealing ring 210. The first sealing ring 210 can cover the heating element 220 from all directions and angles, enhancing the stability of the assembled heating element 220 and preventing the heating element 220 from falling off the first sealing ring 210. Simultaneously, it prevents problems such as product leakage, air leakage, and water ingress, providing structural support to ensure the safety and reliability of product use.

[0103] In some embodiments, exemplarily, such as Figure 3 and Figure 4 As shown, the bracket 222 is provided with a first slot 2222, and at least a portion of the insulating member 224 is located in the first slot 2222; and / or the first sealing ring 210 is provided with a second slot 212, and at least a portion of the bracket 222 is located in the second slot 212, and the heating member 226 abuts against the bottom wall 2122 of the second slot.

[0104] In this embodiment, when the bracket 222 is provided with the first slot 2222, at least a portion of the insulating member 224 is located within the first slot 2222. This arrangement increases the mating area between the bracket 222 and the insulating member 224. The groove wall of the first slot 2222 serves to limit the insulating member 224, ensuring the stability and reliability of the assembly of the insulating member 224, the bracket 222, and the heating element 226. Simultaneously, this structural arrangement also helps to reduce the overall size of the heating component 220, reduce the occupancy rate of the sealing machine 10's internal space, and provide effective structural support for increasing the volume of the vacuum chamber 500.

[0105] When the first sealing ring 210 is provided with the second slot 212, at least a portion of the bracket 222 is located within the second slot 212, and the heating element 226 abuts against the bottom wall 2122 of the second slot. This arrangement can shorten the distance between the heating element 226 and the vacuum chamber 500, allowing the heat generated by the heating element 226 to be effectively and promptly transferred to the bag to be sealed. Simultaneously, this structural arrangement ensures the mating area between the bracket 222 and the first sealing ring 210, and the slot wall of the second slot 212 acts as a limit for the bracket 222, ensuring the stability and reliability of the assembly of the insulating element 224, the bracket 222, and the heating element 226.

[0106] In some embodiments, exemplarily, such as Figure 3 , Figure 4 and Figure 5 As shown, when the first sealing ring 210 is provided with the second slot 212, the distance d from the bottom wall 2122 of the second slot to the side end face of the first sealing ring 210 facing the second sealing ring 400 is greater than or equal to 0.5 mm and less than or equal to 2 mm.

[0107] In this embodiment, the mating structure of the heating element 220 and the first sealing ring 210 is further defined.

[0108] When the first sealing ring 210 is provided with the second slot 212, and the first cover 100 and the second cover 300 are in the closed state, the distance d from the bottom wall 2122 of the second slot to the side end face of the first sealing ring 210 facing the second sealing ring 400 is greater than or equal to 0.5 mm and less than or equal to 2 mm. This setting ensures that the heat generated by the heating component 220 can effectively melt or soften the bag, while also ensuring the safety and reliability of the sealing machine 10.

[0109] If the distance d from the bottom wall 2122 of the second slot to the side face of the first sealing ring 210 facing the second sealing ring 400 is less than 0.5mm, then the distance from the bottom wall 2122 of the second slot to the side face of the first sealing ring 210 facing the second sealing ring 400 is relatively short. In other words, when the first cover 100 and the second cover 300 are in the closed state, the portion of the first sealing ring 210 located between the second sealing ring 400 and the heating element 220 is relatively thin. This portion of the first sealing ring 210 is easily damaged under the heating action of the heating element 220, which can lead to problems such as electrical leakage, air leakage, and water ingress, reducing the product's performance and market competitiveness.

[0110] If the distance d from the bottom wall 2122 of the second slot to the side of the first sealing ring 210 facing the second sealing ring 400 is greater than 2mm, then the distance from the bottom wall 2122 of the second slot to the side of the first sealing ring 210 facing the second sealing ring 400 is relatively large. In other words, when the first cover 100 and the second cover 300 are in the closed state, the portion of the first sealing ring 210 located between the second sealing ring 400 and the heating element 220 is relatively thick, resulting in slow heat transfer, poor sealing effect, and reduced product performance and market competitiveness.

[0111] In some embodiments, exemplarily, such as Figure 3 As shown, when the first sealing ring 210 is provided with the second slot 212, the distance L from the slot sidewall 2124 of the second slot to the outer peripheral wall 214 of the first sealing ring is greater than or equal to 10mm.

[0112] In this embodiment, the mating structure of the heating element 220 and the first sealing ring 210 is further defined.

[0113] When the first sealing ring 210 is provided with the second slot 212, the distance L from the side wall 2124 of the second slot to the outer peripheral wall 214 of the first sealing ring is greater than or equal to 10mm. The first sealing ring 210 includes heating elements 220 on both sides. This setting limits the wrapping length of the first sealing ring 210, which can ensure the stability and reliability of the assembly between the first sealing ring 210 and the heating element 220, and also ensure the area of ​​the heating element 220 for temperature measurement and external heat dissipation.

[0114] For example, the distance L from the groove sidewall 2124 of the second slot to the outer peripheral wall 214 of the first sealing ring includes 11mm, 12mm, 13mm, 14mm, and 15mm, etc., which will not be listed here.

[0115] In some embodiments, exemplarily, such as Figure 2 and Figure 4As shown, when the first cover 100 and the second cover 300 are in the closed state, and the first sealing ring 210 covers a part of the heating component 220, the heating component 220 has a first end 227 and a second end 228 opposite each other along the direction from the second cover 300 to the first cover 100. The first end 227 is located inside the first sealing ring 210, and the second end 228 is exposed outside the first sealing ring 210. The second end 228 is located between the second sealing ring 400 and the end 216 of the first sealing ring that is opposite to the second sealing ring.

[0116] In this embodiment, the mating structure of the first sealing ring 210, the second sealing ring 400, and the heating component 220 is further defined.

[0117] When the first cover 100 and the second cover 300 are in the closed state, and the first sealing ring 210 covers a portion of the heating element 220, the heating element 220 has a first end 227 and a second end 228 opposite to each other, arranged along the direction from the second cover 300 to the first cover 100. The first end 227 is closer to the second sealing ring 400 than the second end 228. The first end 227 is located inside the first sealing ring 210, and the second end 228 is exposed outside the first sealing ring 210, and is located between the second sealing ring 400 and the end 216 of the first sealing ring facing away from the second sealing ring.

[0118] Therefore, the first sealing ring 210 can elevate the heating component 220, thereby separating the heating component 220 from other components in the sealing machine 10. This arrangement of the heating component 220 from other components in the sealing machine 10 prevents the heating component 220 from contacting other components in the sealing machine 10 and causing damage to those components.

[0119] In this embodiment, the mating structure of the first sealing ring 210, the second sealing ring 400, and the heating component 220 is further defined.

[0120] The end face of the heating element 220 that is opposite to the second sealing ring 400 is referred to as the first end face, and the end face of the first sealing ring 210 that is opposite to the second sealing ring 400 is referred to as the second end face.

[0121] The positional relationship between the first end face, the second end face, and the second sealing ring 400 is defined such that the first end face is closer to the second sealing ring 400 than the second end face; that is, the distance from the first end face to the second sealing ring 400 is less than the distance from the second end face to the second sealing ring 400. Therefore, the first sealing ring 210 can elevate the heating element 220, separating it from other components within the sealing machine 10. This spacing prevents the heating element 220 from contacting other components and causing damage.

[0122] In some embodiments, for example, a portion of the second sealing ring 400 forms a pressure strip 420, which abuts against the first sealing ring 210 when the first cover 100 and the second cover 300 are in the closed state.

[0123] In this embodiment, the structure of the second sealing ring 400 is further defined.

[0124] A portion of the second sealing ring 400 forms the pressure strip 420.

[0125] The second sealing ring 400 is arranged around the second sealing chamber 310.

[0126] When the first cover 100 and the second cover 300 are in the closed state, the second sealing ring 400 abuts against the first sealing ring 210; specifically, the pressure strip 420 abuts against the first sealing ring 210. After the vacuum chamber 500 is evacuated, the first sealing ring 210 and the second sealing ring 400 are tightly attracted together, causing the first sealing ring 210 and the pressure strip 420 to abut against each other, effectively sealing the connection between the first sealing chamber 110 and the second sealing chamber 310 to prevent air leakage. The pressure strip 420, under pressure, cooperates with the first sealing ring 210 to tightly press the bag opening, ensuring uniform force distribution in the air vent area and preventing partial unsealing or leaks at the bag opening.

[0127] A portion of the second sealing ring 400 forms a pressure strip 420. This design ensures the effectiveness and feasibility of the seal between the first sealing ring 210 and the second sealing ring 400, while simplifying the internal assembly structure of the sealing machine 10 and reducing the difficulty of operation for the user. Therefore, the second sealing ring 400 not only seals the vacuum chamber 500 but also presses down on the bag opening, enriching its functionality and improving the product's performance.

[0128] In some embodiments, exemplarily, such as Figure 6As shown, the second sealing ring 400 includes: two strip segments 430, which are arranged opposite to each other and spaced apart along a first direction, and one strip segment 430 forms a pressure strip 420; two connecting segments 440, each connecting segment 440 connecting between the two strip segments 430, and the two connecting segments 440 are arranged spaced apart along a second direction; wherein, the length of the strip segment 430 in the second direction is greater than the length of the connecting segment 440 in the first direction.

[0129] In this embodiment, the structure of the second sealing ring 400 is further defined.

[0130] The second sealing ring 400 includes two strip segments 430 and two connecting segments 440.

[0131] Two strip segments 430 are arranged opposite each other and spaced apart along a first direction, and each connecting segment 440 connects the two strip segments 430, and the two connecting segments 440 are arranged spaced apart along a second direction. The two strip segments 430 and the two connecting segments 440 form a runway-shaped structure.

[0132] Specifically, a strip segment 430 forms a pressure strip 420, which satisfies the requirement that a portion of the second sealing ring 400 forms a pressure strip 420.

[0133] In addition, the longer strip segment 430 forms a pressure strip 420. This arrangement helps to extend the length of the pressure strip 420 and the heating element 220, enabling sealing operations for larger bags. Of course, it can also seal smaller bags, providing structural support to ensure the performance of the sealing machine 10.

[0134] In some embodiments, exemplarily, such as Figure 2 As shown, the second sealing ring 400 includes: a sealing ring body 410, the length of the sealing ring body 410 in the first direction being less than the length of the sealing ring body 410 in the second direction; a pressure strip 420 disposed on the sealing ring body 410, at least a portion of the pressure strip 420 protruding from the sealing ring body 410 along the first direction, and the pressure strip 420 extending along the second direction.

[0135] In this embodiment, the structure of the second sealing ring 400 is further defined.

[0136] The second sealing ring 400 includes a sealing ring body 410 and a pressure strip 420. The length of the sealing ring body 410 in the first direction is less than the length of the sealing ring body 410 in the second direction, that is, the sealing ring body 410 has a racetrack-shaped structure.

[0137] The sealing ring body 410 is arranged around the second sealing chamber 310.

[0138] A pressure strip 420 is disposed on the sealing ring body 410. At least a portion of the pressure strip 420 protrudes from the sealing ring body 410 along a first direction, and the pressure strip 420 extends along a second direction. When the first cover 100 and the second cover 300 are in the closed state, the pressure strip 420 abuts against the first sealing ring 210. Specifically, after the vacuum chamber 500 is evacuated, the first sealing ring 210 and the second sealing ring 400 are tightly attracted together, causing the first sealing ring 210 and the pressure strip 420 to abut against each other, effectively sealing the connection between the first sealing chamber 110 and the second sealing chamber 310, preventing air leakage. The pressure strip 420 can cooperate with the first sealing ring 210 under pressure to tightly press the bag opening, ensuring uniform force distribution in the air vent area and preventing partial unsealing or leaks at the bag opening.

[0139] The pressure strip 420 is located on the sealing ring body 410. This arrangement ensures the effectiveness and feasibility of sealing the first sealing ring 210 and the second sealing ring 400, while simplifying the internal assembly structure of the sealing machine 10 and reducing the difficulty of operation for users.

[0140] In addition, the pressure strip 420 extends along the second direction. This arrangement helps to extend the length of the pressure strip 420 and the heating element 220, enabling sealing operations for larger bags. Of course, it can also seal smaller bags, providing structural support to ensure the performance of the sealing machine 10.

[0141] When the first cover 100 and the second cover 300 are in the closed state, the sealing ring 410 and the pressure strip 420 both abut against the first sealing ring 210.

[0142] In some embodiments, for example, when the first cover 100 and the second cover 300 are in the closed state, the pressure strip 420 is disposed opposite to the heating component 220.

[0143] In this embodiment, the mating structure of the pressure strip 420 and the heating element 220 is further defined. This ensures that when the first cover 100 and the second cover 300 are in the closed state, the pressure strip 420 and the heating element 220 are positioned opposite each other. That is, the positional relationship between the pressure strip 420 and the heating element 220 is defined. The pressure strip 420 can tightly press the bag opening onto the heating element 220, causing the bag opening to melt and adhere upon heating, ensuring the flatness and strength of the bag opening seal. Because the pressure strip 420 and the heating element 220 are positioned opposite each other, the mating position of the bag opening pressed by the pressure strip 420 and the heating element 220 can be guaranteed, allowing the bag opening to be aligned with the heating element 220, providing structural support for ensuring the effectiveness and feasibility of the sealing.

[0144] In some embodiments, exemplarily, such as Figure 7As shown, the first cover 100 and the second cover 300 are rotatably connected, and the pressure strip 420 is located on the side of the second sealing chamber 310 away from the rotatable connection between the first cover 100 and the second cover 300.

[0145] In this embodiment, the mating structure of the pressure strip 420, the second sealing chamber 310, the first cover 100, and the second cover 300 is further defined.

[0146] The first cover 100 and the second cover 300 are rotatably connected, and one of the first cover 100 and the second cover 300 can rotate relative to the other to meet the use requirement that the first cover 100 and the second cover 300 can be opened and closed.

[0147] The pressure strip 420 is located on the side of the second sealing chamber 310 away from the rotatable connection between the first cover 100 and the second cover 300. When the first cover 100 and the second cover 300 are in the closed state, the pressure strip 420 is positioned opposite to the heating element 220. Therefore, the heating element 220 is located on the side of the second sealing chamber 310 away from the rotatable connection between the first cover 100 and the second cover 300. Therefore, it can be seen that the pressure strip 420 and the heating element 220 are both close to the opening 800 of the first cover and the second cover, which can reduce the distance between either the pressure strip 420 or the heating element 220 and the opening 800 of the first cover and the second cover. In this way, when vacuuming the bag, the area of ​​the bag extending into the vacuum chamber 500 can be reduced, which makes it possible to effectively vacuum and seal bags of various sizes. For example, small bags can be effectively vacuumed and sealed, and large bags can be vacuumed and sealed. This can improve the adaptability of the sealing machine 10 and help improve its performance and market competitiveness.

[0148] For example, when the first sealing ring 210 is provided with the second slot 212, the distance d from the bottom wall 2122 of the second slot to the side end face of the first sealing ring 210 facing the second sealing ring 400 includes 0.8mm, 1mm, 1.2mm, 1.5mm, 1.6mm and 1.8mm, etc., which will not be listed here.

[0149] For example, the length of the pressure strip 420 in the second direction is greater than the length of the connecting segment 440 in the first direction.

[0150] For example, the length of the heating component 220 in the second direction is greater than the length of the connecting segment 440 in the first direction.

[0151] When the first cover 100 and the second cover 300 are in the closed state, the sealing ring 410 and the pressure strip 420 both abut against the first sealing ring 210.

[0152] For example, the length of the pressure strip 420 in the second direction is greater than the length of the sealing ring body 410 in the first direction.

[0153] For example, the length of the heating component 220 in the second direction is greater than the length of the sealing ring body 410 in the first direction.

[0154] For example, the second sealing ring 400 is integrally formed with a pressure strip 420. This structural configuration simplifies the molding process of the second sealing ring 400 by eliminating the assembly process of the pressure strip 420, which helps to improve the processing efficiency of the product. In addition, the integral formation of the pressure strip 420 on the second sealing ring 400 can ensure the dimensional accuracy of the product.

[0155] For example, the first sealing ring 210 and the heating element 220 are integrally formed. This structural configuration simplifies the molding process by eliminating the assembly process of the first sealing ring 210 and the heating element 220, thus improving product processing efficiency. In addition, the integral formation of the first sealing ring 210 and the heating element 220 ensures the dimensional accuracy of the product.

[0156] For example, the length of the heating component 220 in the second direction is less than the length of the first sealing ring 210 in the first direction.

[0157] For example, such as Figure 1 As shown, the sealing machine 10 includes a first cover 100, a second cover 300, a second sealing ring 400, a vacuum pump 600, a heating element 220, and a circuit board 700. The first cover 100 includes a first sealing chamber 110, a bottom cover 120, and a lower cover 130. The second cover 300 includes a second sealing chamber 310, a housing 320, and an upper cover 330.

[0158] For example, the first sealing ring 210 and the heating element 220 are an integral structure. The heating element 220 is wrapped around the first sealing ring 210. The second sealing ring 400 has a pressure strip 420 integrally formed thereon. The pressure strip 420 and the heating element 220 are respectively installed on the upper cover 330 and the lower cover 130, and the pressure strip 420 and the heating element 220 are located in corresponding upper and lower positions. Figure 3 , Figure 4 and Figure 5As shown, when the first cover 100 and the second cover 300 are in the closed state, the distance from the bottom wall 2122 of the second slot to the end face of the first sealing ring 210 facing the second sealing ring 400 is d, where 0.5mm ≤ d ≤ 2mm. When d > 2mm, the thickness of the portion of the first sealing ring 210 between the second sealing ring 400 and the heating element 220 is too thick, resulting in slow heat transfer and poor sealing effect. When d < 0.5mm, the thickness of the portion of the first sealing ring 210 between the second sealing ring 400 and the heating element 220 is too thin, making the first sealing ring 210 prone to breakage, which can lead to problems such as product leakage, air leakage, and water ingress. The first sealing ring 210 has wrapping portions 230 on both sides, with a gap between the wrapping portions 230 to partially wrap the heating element 220. The wrapping part 230 is used to wrap the heating element 220. The heating element 220 exposes the first sealing ring 210 through the notch, which facilitates temperature measurement of the heating element 220 and heat dissipation of the heating element 220.

[0159] For example, by integrating the first sealing ring 210 with the heating element 220, the second sealing ring 400 integrates the pressure strip 420. This arrangement simplifies the internal structure of the sealing machine 10 and reduces the difficulty of user operation.

[0160] For example, the first sealing ring 210 and the heating element 220 can also be fully enclosed to prevent the heating element 220 from being exposed.

[0161] For example, the heating element 220 is integrated with the first sealing ring 210, and the pressure strip 420 is integrated with the sealing ring body 410.

[0162] The first sealing ring 210 has wrapping portions 230 on both sides, and the middle of the heating element 220 is exposed for heat dissipation.
