The base includes a first retaining ring and a second retaining ring connected in sequence. The first retaining ring forms a first working groove, and the second retaining ring forms a second working groove. The first and second working grooves are interconnected. The first sealing ring is assembled in the first working groove and connected to the first retaining ring.

Description

Technical Field

[0001] This invention relates to the technical field of sealing joints, and more particularly to sealing joints. Background Technology

[0002] Mason jars are widely used in food storage and pickling due to their excellent sealing performance and diverse applications. In practical use, vacuum sealing of the inside of the jar is often necessary to extend the shelf life of the contents. However, most existing vacuum sealing equipment is designed for single-diameter Mason jars, requiring users to equip and replace multiple sets of sealing adapters of different specifications when dealing with Mason jars of different sizes or diameters. This not only increases equipment procurement and management costs but also cumbersome operating procedures, impacting work efficiency. Furthermore, existing sealing adapters often require repeated disassembly, assembly, and calibration during replacement, which can easily lead to incomplete seals and leaks, reducing the reliability of the seal and the practicality of the product.

[0003] In existing technologies, some sealing devices attempt to adapt to containers of different diameters by replacing components such as sealing rings. However, due to limitations in structural design, problems often arise such as loose fit between the sealing ring and the tank, low air extraction efficiency, and inconvenient maintenance and cleaning, making it difficult to meet users' sealing needs for high efficiency, convenience, and multi-specification compatibility. Therefore, how to provide a device that is simple in structure, easy to operate, compatible with Mason jars of different diameters, and achieves efficient and reliable sealing has become an urgent technical problem to be solved in this field. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides a sealing joint: the sealing joint includes a base, a first sealing ring, and a second sealing ring; the base includes a first retaining ring and a second retaining ring connected in sequence, the first retaining ring forming a first working groove, the second retaining ring forming a second working groove, and the first and second working grooves communicating with each other; the first sealing ring is assembled in the first working groove and connected to the first retaining ring; the second sealing ring is assembled in the second working groove and connected to the second retaining ring, the inner diameter of the second sealing ring being larger than the inner diameter of the first sealing ring; wherein, when a first Mason jar is assembled in the first working groove and contacts the first sealing ring, a suction machine is assembled in the second working groove; when a second Mason jar is assembled in the second working groove and contacts the second sealing ring, a suction machine is assembled in the first working groove.

[0005] The present invention also includes a sealing device comprising a suction machine and a sealing joint as described in any of the above claims, wherein the suction machine and the sealing joint are detachably connected.

[0006] The beneficial effects of this invention are as follows: This embodiment, through an innovative structural design of the sealing joint, proposes an effective solution to the technical problems in the prior art, such as poor sealing adaptability, complex operation, and insufficient sealing reliability when sealing Mason jars of different diameters. Specifically, the sealing joint includes a base, a first sealing ring, and a second sealing ring. The base is provided with a first retaining ring and a second retaining ring. The first retaining ring and the second retaining ring respectively form a first working groove and a second working groove that are interconnected, so that the first working groove and the second working groove can be flexibly assembled and connected with the suction machine and the Mason jar, respectively.

[0007] This structural design allows the sealing joint to accommodate Mason jars of different diameters. The first and second sealing rings are respectively positioned within their respective working grooves, with different inner diameters, thus precisely matching Mason jars of different sizes and improving the tightness and reliability of the seal.

Detailed Implementation

[0012] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, clearly and comprehensively demonstrating the technical solutions. It should be noted that the listed embodiments are only a part of the present invention, and not all possible implementations. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0013] Please see Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the sealing device provided in an embodiment of the present invention. Figure 2 This is a cross-sectional schematic diagram of the sealing device provided in an embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of a sealing joint 100 provided in an embodiment of the present invention.

[0014] This invention relates to a sealing device comprising a suction machine 200 and a sealing joint 100, which are detachably connected. Mason jars of corresponding diameters can be fitted to opposite ends of the sealing joint 100. After a Mason jar is fitted to one end of the sealing joint 100, the suction machine 200 is fitted to the other end, thereby creating a vacuum at one end of the sealing joint 100 to seal the Mason jar. Similarly, after replacing the Mason jar with one of a different diameter, it can be fitted to the other end of the sealing joint 100, and the suction machine 200 can be fitted to the opposite end to create a vacuum. The suction machine 200 operates primarily by pumping air.

[0015] The sealing device provided in this embodiment addresses the technical problems of existing technologies where sealing Mason jars of different diameters requires replacing multiple sets of adapters, resulting in cumbersome operation and low efficiency. It proposes a simple and highly compatible sealing solution. This sealing device features a structure where both ends of the sealing joint 100 are designed to accommodate Mason jars of different diameters. This eliminates the need for the user to replace the entire sealing device; instead, the user simply assembles the Mason jar of the desired diameter onto the corresponding end of the sealing joint 100 and connects the suction machine 200 to the other end to achieve vacuum sealing.

[0016] Through the above structural design, this technical solution effectively simplifies the operation process, improves the convenience and efficiency of sealing work, and reduces equipment replacement and maintenance costs. Meanwhile, the suction unit 200 and sealing joint 100 of the sealing equipment adopt a detachable connection method, facilitating cleaning, storage, and portability, enhancing the practicality and flexibility of the equipment. In summary, this technical solution can efficiently and conveniently seal Mason jars of different diameters, significantly improving the applicability of the sealing equipment and the user experience, achieving the expected technical results.

[0017] The sealing joint 100 includes a base 10, a first sealing ring 20, and a second sealing ring 30. The base 10 includes a first retaining ring 12 and a second retaining ring 13 connected to each other. The first retaining ring 12 forms a first working groove 101, and the second retaining ring 13 forms a second working groove 102. The first working groove 101 and the second working groove 102 are interconnected. The first sealing ring 20 is assembled in the first working groove 101 and connected to the first retaining ring 12. The second sealing ring 30 is assembled in the second working groove 102 and connected to the second retaining ring 13. The inner diameter of the second sealing ring 30 is larger than the inner diameter of the first sealing ring 20. When a first Mason jar is assembled in the first working groove 101 and contacts the first sealing ring 20, a suction machine 200 is assembled in the second working groove 102, aligned with the first working groove 101. When a second Mason jar is assembled in the second working groove 102 and contacts the second sealing ring 30, a suction machine 200 is assembled in the first working groove 101, aligned with the second working groove 102.

[0018] Taking the assembly of a first Mason jar in the first working tank 101 as an example, the first Mason jar is assembled into the first working tank 101, and the suction machine 200 is assembled into the second working tank 102. When the suction machine 200 works, it draws out the air in the first working tank 101 to form a negative pressure environment. The atmospheric pressure presses the first sealing ring 20 against the outer peripheral wall of the first Mason jar, thereby achieving the sealing effect.

[0019] This embodiment proposes an effective solution to the technical problems in the prior art, such as poor sealing adaptability, complex operation, and insufficient sealing reliability, by innovatively designing the sealing joint 100. Specifically, the sealing joint 100 includes a base 10, a first sealing ring 20, and a second sealing ring 30. The base 10 is provided with a first retaining ring 12 and a second retaining ring 13 that are connected to each other. The first working groove 101 and the second working groove 102 are interconnected, enabling flexible assembly and connection with the suction machine 200 and the Mason jar, respectively.

[0020] This structural design allows the sealing joint 100 to simultaneously accommodate Mason jars of different diameters. The first sealing ring 20 and the second sealing ring 30 are respectively positioned in their corresponding working grooves with different inner diameters, thus precisely matching Mason jars of different sizes and improving the tightness and reliability of the seal. The interconnected arrangement of the first working groove 101 and the second working groove 102 ensures that regardless of which end of the Mason jar is assembled, the other end can be connected to the suction machine 200 to effectively evacuate the required sealing space.

[0021] Taking the assembly of the first working tank 101 with the first Mason jar as an example, the suction machine 200 is connected to the first working tank 101 through the second working tank 102, extracting air from the first working tank 101 to create a negative pressure. This negative pressure causes atmospheric pressure to press the first sealing ring 20 tightly against the outer circumferential wall of the first Mason jar, achieving a highly efficient seal. This structure is also applicable to the combination of the second working tank 102 and the second Mason jar, greatly improving the versatility and convenience of the equipment.

[0022] In summary, this technical solution, through reasonable structural partitioning and sealing ring configuration, flexibly adapts to different specifications of Mason jars, is easy to operate, effectively improves sealing efficiency and reliability, reduces the complexity of replacing parts and the operation process, thereby achieving efficient sealing of Mason jars of various specifications, and achieving the technical effects of expanding the scope of application, simplifying the operation process and enhancing sealing performance.

[0023] The base 10 also includes a partition 11, a first retaining ring 12 and a second retaining ring 13 respectively disposed on opposite sides of the partition 11, the partition 11 and the first retaining ring 12 together forming a first working groove 101, the partition 11 and the second retaining ring 13 together forming a second working groove 102, the partition 11 having a vent hole 103, the vent hole 103 communicating with the first working groove 101 and the second working groove 102 respectively; a first sealing ring 20 is assembled in the first working groove 101 and connected to the first retaining ring 12; the second The sealing ring 30 is assembled in the second working groove 102 and connected to the second retaining ring 13. The inner diameter of the second sealing ring 30 is larger than the inner diameter of the first sealing ring 20. When the first Mason jar is assembled in the first working groove 101 and contacts the first sealing ring 20, the suction machine 200 is assembled in the second working groove 102, aligned with the vent hole 103. When the second Mason jar is assembled in the second working groove 102 and contacts the second sealing ring 30, the suction machine 200 is assembled in the first working groove 101, aligned with the vent hole 103.

[0024] The partition 11 can support the suction machine 200. A vent 103 is provided on the partition 11 to connect the first working slot 101 and the second working slot 102. Therefore, after assembling the suction machine 200, it only needs to be connected to the vent 103, thus improving sealing and exhaust efficiency. This technical solution solves the problem that when working slots of different diameters are located on one side of the partition 11, and when a smaller diameter Mason jar is being vacuumed, the smaller diameter Mason jar is inserted deep into the larger working slot, resulting in a large distance and causing inaccurate positioning of the sealing cap and vacuuming failure.

[0025] Please see Figures 1 to 4 As shown, Figure 4 This is a schematic diagram of the base 10 provided in an embodiment of the present invention from a first perspective.

[0026] The base 10 also includes a first limiting plate 14 and a second limiting plate 15. The first limiting plate 14 and the second limiting plate 15 are spaced apart on the inner wall of the first retaining ring 12 to form a first limiting groove 104, and the first sealing ring 20 is assembled in the first limiting groove 104. In this embodiment, by adding a first limiting plate 14 and a second limiting plate 15 to the base 10 and spaced them apart on the inner wall of the first retaining ring 12, a first limiting groove 104 is formed, and the first sealing ring 20 is securely assembled in the first limiting groove 104. This structural design effectively solves the technical problems in the prior art, such as the sealing ring being prone to positional displacement, inaccurate assembly, or loosening after long-term use.

[0027] The first sealing ring 20 is dually limited in both the radial and axial directions by the first retaining ring 12, the first limiting plate 14, and the second limiting plate 15, ensuring that the first sealing ring 20 is always kept in the predetermined position, effectively improving the fit between the sealing ring and the outer peripheral wall of the Mason jar and the sealing reliability. Furthermore, the limiting structure facilitates the quick and accurate installation and replacement of the sealing ring, simplifies maintenance operations, and extends the product's lifespan and user experience.

[0028] In summary, this technical solution, through the innovative design of the limiting plate structure, achieves precise positioning and stable fixation of the first sealing ring 20, solving problems such as easy displacement and detachment of the sealing ring, thereby significantly improving the sealing effect and operational reliability of the sealing device, and achieving the technical effect of improving sealing performance and structural stability.

[0029] The first sealing ring 20 includes a first fixing part 21, a first connecting part 22 and a first sealing part 23 connected in sequence. The first fixing part 21 and the first sealing part 23 form a first deformation cavity 25 at intervals. The opposite ends of the first fixing part 21 are respectively connected to the first limiting plate 14 and the second limiting plate 15. Atmospheric pressure applies a force to the first sealing part 23 through the first deformation cavity 25. The first sealing part 23 is used to contact the first Mason jar.

[0030] This embodiment innovatively designs the structure of the first sealing ring 20, dividing it into a first fixing part 21, a first connecting part 22, and a first sealing part 23 connected sequentially. A first deformation cavity 25 is formed between the first fixing part 21 and the first sealing part 23. Simultaneously, both ends of the first fixing part 21 are connected to the first limiting plate 14 and the second limiting plate 15, respectively. This structure effectively solves the problems of unstable sealing effect, poor fit, and inability of the sealing ring to fully deform to achieve a good seal under negative pressure in the prior art.

[0031] Specifically, the first deformation cavity 25 allows atmospheric pressure to apply pressure to the first sealing part 23 when the suction machine 200 operates and creates negative pressure. Under the action of external atmospheric pressure, the first sealing part 23 can undergo elastic deformation, thereby fitting more tightly against the outer peripheral wall of the first Mason jar, significantly improving sealing performance. Simultaneously, the connection between the first fixing part 21 and the limiting plate ensures stable positioning of the sealing ring, preventing displacement and detachment during installation and use, and improving the reliability of the sealing structure.

[0032] In summary, this technical solution, through the ingenious design of the first deformation cavity 25 and the reasonable division of labor among the various parts of the sealing ring, ensures the stable positioning of the sealing ring while utilizing atmospheric pressure to achieve adaptive deformation of the sealing parts. This effectively solves technical problems such as sealing failure and sealing ring displacement, thereby achieving the technical effects of stable sealing effect, strong fit and structural reliability.

[0033] The width of the first fixing part 21 is greater than or equal to the width of the first limiting plate 14, thereby preventing the first limiting plate 14 from extending beyond the first deformation cavity 25. The width of the second limiting plate 15 is greater than the width of the first limiting plate 14, and the second limiting plate 15 is further connected to the first connecting part 22.

[0034] In this embodiment, by designing the width of the first fixing part 21 to be greater than or equal to the width of the first limiting plate 14, the edge of the first limiting plate 14 can be effectively prevented from extending into the first deformation cavity 25, thus avoiding the limiting plate partially blocking the normal entry of external air into the first deformation cavity 25. This ensures that the first deformation cavity 25 can smoothly communicate with the external air, and that atmospheric pressure can be fully utilized to exert force on the first sealing part 23 during operation, promoting full deformation and effective fit of the first sealing part 23, thereby improving the sealing effect.

[0035] Furthermore, the width of the second limiting plate 15 is set to be greater than the width of the first limiting plate 14, and the second limiting plate 15 is further connected to the first connecting part 22. This structural design further strengthens the fixing and limiting effect on the first sealing ring 20, effectively preventing axial displacement and detachment of the sealing ring during use. At the same time, the connection between the second limiting plate 15 and the first connecting part 22 can improve the overall structural strength and stability of the first sealing ring 20, ensuring that the sealing ring maintains its predetermined working state under pressure, further improving the reliability of the sealing device.

[0036] In summary, this technical solution, by optimizing the width fit between the limiting plate and the first fixing part 21 and the connection between the second limiting plate 15 and the first connecting part 22, solves the problems in the prior art such as the limiting plate obstructing the deformation cavity and affecting the air pressure effect, and the sealing ring not being firmly positioned. This achieves the technical effect of atmospheric pressure being able to fully enter the deformation cavity, the sealing part deforming and fitting fully, and the structure being stable and reliable, significantly improving the sealing performance and service life of the sealing device.

[0037] A first chamfer 24 is provided on the outer peripheral surface of the first sealing part 23 away from the first connecting part 22 and away from the first deformation cavity 25. The first chamfer 24 can be a bevel or a rounded corner. Specifically, the first chamfer 24 makes the end transition of the first sealing part 23 smoother. When the first working groove 101 is installed into the first Mason jar, the first chamfer 24 can reduce resistance and interference during the assembly process, making it easier for the first Mason jar to slide in smoothly and fit against the first sealing part 23, effectively reducing the installation difficulty. At the same time, the first chamfer 24 can avoid local stress concentration caused by the protruding edges of the end of the first sealing part 23, reducing the risk of end breakage and deformation, thereby improving the durability and service life of the sealing ring.

[0038] In addition, the structure of the first chamfer 24 can also make the first sealing part 23 and the sealed surface more closely and evenly contacted, improve the sealing performance and prevent leakage.

[0039] In summary, this technical solution solves the problems of inconvenient sealing ring assembly, easy end damage, and poor sealing by setting a chamfer structure on the outer peripheral surface of the first sealing part 23, and achieves the technical effects of smooth sealing ring assembly, durable ends, and better sealing effect.

[0040] A channel 105 is formed along the axial direction of the vent 103, passing sequentially through the first limiting plate 14 and the second limiting plate 15, to facilitate the extraction of air from the first working groove 101 by the suction machine 200 during operation. In this embodiment, by setting the channel 105 along the axial direction of the vent 103, passing sequentially through the first limiting plate 14 and the second limiting plate 15, the channel 105 structurally penetrates the entire limiting structure. This technical solution effectively solves the technical problem in the prior art where air cannot be smoothly extracted due to the obstruction of the first limiting plate 14 and the second limiting plate 15.

[0041] Specifically, the through channel 105 enables the suction machine 200 to efficiently and quickly extract air from the first working slot 101 during operation. This ensures the continuity of the suction process, improves suction efficiency, and avoids problems such as obstructed airflow affecting sealing or suction performance.

[0042] The base 10 also includes a gap plate 16, which is located in the channel 105 and connected to the first retaining ring 12. The gap plate 16 can locally strengthen the structural strength of the base 10 at the position of the channel 105, and can also limit the position of the first Mason jar. Through the above structural design, the gap plate 16 can effectively solve the technical problems in the prior art such as insufficient structural strength and easy deformation of the channel 105 part of the base 10, and unreliable limiting of the first Mason jar.

[0043] Specifically, the gap plate 16 provides local reinforcement to the base 10 at the channel 105, enhancing its mechanical strength and stability and preventing deformation or damage to the channel 105 during suction, handling, or use, thereby extending the service life of the base 10. Furthermore, the gap plate 16, in conjunction with the first retaining ring 12, effectively limits the movement of the first Mason jar, preventing it from shaking, shifting, or falling off during installation, suction, or other operations, thus improving product safety and operational reliability.

[0044] In summary, this technical solution solves the problems of insufficient structural strength of the base 10 channel 105 and unreliable limiting of the first Mason jar by setting and connecting the gap plate 16 in the base 10 channel 105, and achieves the technical effect of local structural reinforcement of the base 10 and reliable limiting of the first Mason jar.

[0045] The width of the gap plate 16 is less than or equal to the width of the second limiting plate 15. In this embodiment, by designing the width of the gap plate 16 to be less than or equal to the width of the second limiting plate 15, the synergistic effect of the gap plate 16 and the second limiting plate 15 in limiting the first Mason jar is achieved. This technical solution effectively solves the technical problem in the existing structure that when the second limiting plate 15 fails due to wear, deformation, or other reasons, the first Mason jar is prone to shaking and displacement, resulting in reduced limiting reliability.

[0046] Specifically, when the second limiting plate 15 is working normally, its large width provides the main limiting function for the first Mason jar, ensuring the stable positioning of the Mason jar. When the second limiting plate 15 fails for any reason, the gap plate 16, due to its reasonable width design, can play an auxiliary limiting role in a timely manner, effectively preventing the first Mason jar from shifting or falling off, thereby ensuring the safety of the equipment and the reliability of the structure.

[0047] In summary, this technical solution, by reasonably limiting the width of the gap plate 16, enables it to assist in limiting the first Mason tank when the second limiting plate 15 fails, thus solving the risk caused by single-point failure of the limiting structure. It achieves redundant design of the limiting function and improves the reliability of the overall limiting structure, ensuring the stability and safety of the equipment during long-term use.

[0048] The base 10 also includes a plurality of protrusions 17 disposed on opposite sides of the partition 11. The protrusions 17 are used to hold the mouths of the first and second Mason jars. Taking the first Mason jar as an example, the protrusions 17 can ensure that the first Mason jar is separated from the partition 11 to form a gas flow channel 105, so as to allow the gas in the first working tank 101 to be smoothly extracted.

[0049] In this embodiment, the base 10 is provided with a plurality of protrusions 17, which are distributed on opposite sides of the partition 11 to support the mouths of the first and second Mason jars. This structural design effectively solves the problem of direct contact between the mouth of the Mason jar and the partition 11, and obstruction of the gas flow channel 105.

[0050] Specifically, the multiple protrusions 17 ensure a certain gap between the mouth of the first Mason jar and the partition 11 when the first Mason jar is installed, thus forming a continuous and stable gas flow channel 105 between them. Through this gas flow channel 105, the gas in the first working chamber 101 can be smoothly extracted, avoiding the problem of gas obstruction caused by a tight fit between the mouth of the jar and the partition 11. Furthermore, the protrusions 17 also limit and support the mouth of the first Mason jar, preventing the jar from shaking or shifting during assembly and operation, further improving the sealing performance and operational stability of the device.

[0051] In summary, this technical solution solves the technical problem of obstructed gas flow channel 105 caused by direct contact between the mouth of the Mason jar and the partition 11 by setting multiple protrusions 17 on both sides of the partition 11, thus achieving the technical effect of smooth gas extraction and improving the positioning accuracy and operational reliability of the Mason jar.

[0052] Multiple protrusions 17 surround the axis of the vent 103, forming a first ring and a second ring from the inside out. The first ring contains multiple protrusions 17 spaced apart from each other, and the second ring also contains multiple protrusions 17 spaced apart from each other. In this embodiment, multiple protrusions 17 surround the axis of the vent 103, forming a first ring and a second ring sequentially from the inside out, with multiple protrusions 17 in both the first and second rings distributed at intervals. This technical solution effectively solves the technical problems of the prior art, such as a single gas flow channel 105, low flow efficiency, or insufficient support stability.

[0053] Specifically, the two rings of protrusions 17, spaced apart, form multiple support points between the mouth of the Mason jar and the partition 11, improving the stability of the mouth and effectively preventing it from tilting, shaking, or deforming due to uneven force. Simultaneously, the spaced arrangement of the protrusions 17 creates multiple evenly distributed gas flow channels 105 around the vent 103, preventing obstruction of gas flow and allowing gas to be extracted from the working chamber more efficiently and smoothly, thus improving overall extraction efficiency.

[0054] In addition, the double-ring structure can further improve the limiting and buffering effect, making the gap between the bottle mouth and the partition 11 more uniform, which helps to extend the service life of related components and the operational reliability of the equipment.

[0055] In summary, this technical solution, by setting two rings of spaced protrusions 17 around the vent 103, not only improves the support and limiting effect of the bottle mouth, but also optimizes the distribution of the gas flow channel 105, solving the technical problems of low gas flow efficiency and insufficient support stability, and achieving the technical effects of smooth gas extraction and stable positioning of the Mason jar.

[0056] The protrusions 17 in the first ring extend around the axis of the vent 103, while the protrusions 17 in the second ring extend towards the axis of the vent 103. This technical solution addresses the problems of simple support structures, poor limiting effects, and poor gas flow around the vent 103 in existing technologies by setting protrusions 17 extending around the axis of the vent 103 in the first ring and protrusions 17 extending towards the axis of the vent 103 in the second ring, proposing an optimized structural design. Specifically, the protrusions 17 extending around the axis of the vent 103 in the first ring form a continuous annular support structure around the vent 103, effectively limiting the radial movement of components such as the bottle mouth and improving the stability and uniformity of the limiting effect. The protrusions 17 extending towards the axis of the vent 103 in the second ring are radially distributed towards the center of the vent 103, further strengthening the axial limiting effect on the bottle mouth, while simultaneously forming multiple dispersed gas flow channels 105 between the bottle mouth and the partition 11. Through the synergistic effect of the above structures, not only is the positioning and support between components improved, but the gas flow path is also optimized, facilitating smooth gas discharge, increasing extraction efficiency, and reducing airflow resistance. Furthermore, the rationally distributed protrusions 17 disperse stress, reduce localized wear, and improve overall sealing performance and the lifespan of the device. Therefore, this technical solution, through the combined design of annular and radial protrusions 17, effectively solves the problems of support, positioning, and gas flow in existing technologies, achieving higher sealing reliability and component durability.

[0057] The base 10 also includes a third retaining ring 18, which is respectively disposed on opposite sides of the partition 11 and surrounds the axis of the vent 103. The suction port of the suction machine 200 is arranged around the third retaining ring 18.

[0058] This technical solution addresses the problems of insufficient sealing of the suction port of the suction machine 200, easy leakage, and poor working stability in the prior art by adding a third retaining ring 18 to the base 10 and setting the third retaining ring 18 on opposite sides of the partition 11 and surrounding the axis of the vent 103. Specifically, the third retaining ring 18 allows the suction port of the suction machine 200 to surround and fit the third retaining ring 18, thereby forming a multi-layer sealing structure between the suction port and the base 10, effectively preventing gas leakage and significantly improving the sealing performance at the suction port. Simultaneously, the third retaining ring 18, as a structural support ring, not only enhances the assembly stability between the suction machine 200 and the base 10 but also effectively limits the shaking and displacement of the suction machine 200 during operation, improving overall operational stability. Furthermore, the double-sided third retaining ring 18 further disperses the force, reduces local stress concentration, and extends the service life of the device. In summary, this technical solution, by adding a third retaining ring 18, effectively solves the technical problems of insufficient sealing and stability, and achieves the technical effects of improved sealing performance and more stable and reliable operation of the suction machine 200.

[0059] Please see Figures 1 to 5 As shown, Figure 5 This is a schematic diagram of the base 10 provided in an embodiment of the present invention from a second perspective.

[0060] The sealing joint 100 also includes a retaining ring 40, which is assembled in the second working groove 102 and connected to the base 10. A second limiting groove 106 is formed between the retaining ring 40 and the partition 11, and a second sealing ring 30 is assembled in the second limiting groove 106. This technical solution adds a retaining ring 40 to the structure of the sealing joint 100, assembling the retaining ring 40 within the second working groove 102 and connecting it to the base 10. Through this structure, a second limiting groove 106 is formed between the retaining ring 40 and the partition 11, and the second sealing ring 30 is assembled in the second limiting groove 106. This design addresses the technical problems of inaccurate sealing ring positioning, easy detachment, and poor sealing reliability in the prior art, proposing effective improvement measures.

[0061] Specifically, the fixing ring 40 reliably confines the second sealing ring 30 within the second limiting groove 106, preventing displacement or detachment of the sealing ring during assembly and use due to pressure, vibration, or other reasons. This ensures the sealing ring is always in its optimal working position, improving the stability and reliability of the sealing structure. Simultaneously, the connection between the fixing ring 40 and the base 10 further enhances the rigidity of the overall structure, effectively preventing sealing failure caused by deformation of the sealing parts under stress. Furthermore, the precise positioning of the limiting groove allows the second sealing ring 30 to fully fit with the corresponding component, improving the sealing effect and effectively preventing gas or liquid leakage.

[0062] In summary, this technical solution, by setting a fixing ring 40 to form a second limiting groove 106 and assembling a second sealing ring 30, not only solves the technical problems of easy displacement of the sealing ring and poor sealing, but also improves the sealing performance and extends the service life of the device, thereby achieving the technical effect of stable structure and reliable sealing.

[0063] The retaining ring 40 and the base 10 are snapped together. After the second sealing ring 30 is installed, the retaining ring 40 is installed. After the retaining ring 40 is snapped together with the base 10, the retaining ring 40 simultaneously limits and fixes the second sealing ring 30.

[0064] This technical solution optimizes the assembly and positioning of the second sealing ring 30 by employing a snap-fit ​​connection between the fixing ring 40 and the base 10. It effectively addresses the problems of inconvenient installation, inaccurate positioning, and easy detachment of the sealing ring in existing technologies. Specifically, after the second sealing ring 30 is installed in its corresponding position, the fixing ring 40 is then assembled, and the snap-fit ​​structure ensures a reliable connection between the fixing ring 40 and the base 10. The fixing ring 40 simultaneously positions and fixes the second sealing ring 30 while the snap-fit ​​connection is in place.

[0065] Through the above structural design, the snap-fit ​​connection between the fixing ring 40 and the base 10 simplifies the assembly process, improves assembly efficiency, and avoids the risk of displacement or detachment of the sealing ring due to vibration or pressure changes during subsequent use, thereby significantly improving the positioning accuracy and sealing reliability of the sealing ring. Furthermore, this structure ensures that the second sealing ring 30 is always in the predetermined working position, effectively enhancing sealing performance, preventing media leakage, and extending the product's service life.

[0066] The base 10 also includes an elevation portion 19, which is connected to the second retaining ring 13. A second limiting groove 106 is formed between the elevation portion 19 and the fixing ring 40. The elevation portion 19 raises the second sealing ring 30, thereby moving the second sealing ring 30 away from the mouth of the second Mason jar, so as to ensure that the second sealing ring 30 and the peripheral wall of the second Mason jar fit together.

[0067] This technical solution adds an elevating part 19 to the base 10 and connects it to the second retaining ring 13, forming a second limiting groove 106 between the elevating part 19 and the fixing ring 40, within which the second sealing ring 30 is precisely confined. The elevating part 19 appropriately raises the second sealing ring 30, effectively preventing it from directly contacting or approaching the mouth of the second Mason jar.

[0068] The above structural design solves the technical problem in the prior art where the second sealing ring 30 easily comes into contact with the tank opening, leading to poor adhesion between the sealing ring and the tank wall, incomplete sealing, or even localized leakage. The raising effect of the lifting portion 19 allows the second sealing ring 30 to be located further away from the tank opening, promoting a full fit between the second sealing ring 30 and the circumferential wall of the second Mason jar, effectively improving the integrity and reliability of the seal. Furthermore, the tight fit between the second sealing ring 30 and the tank wall helps improve sealing performance, prevents gas or liquid leakage, and thus extends the service life of the sealing structure.

[0069] In summary, this technical solution, through the raised section 19 structure on the base 10, reasonably adjusts the position and bonding method of the second sealing ring 30, successfully solving the problems of loose bonding and poor sealing effect of the sealing ring, achieving reliable bonding between the sealing ring and the tank wall, improving the sealing performance and durability of the overall sealing structure, and achieving the ideal technical effect.

[0070] The heightening section 19 has multiple spaced-apart material reduction grooves 107, which partially reduce the thickness of the heightening section 19. This technical solution aims to solve the technical problems of low material utilization, large overall weight, and high processing cost of the heightening section 19 in the prior art by setting multiple spaced-apart material reduction grooves 107 on the heightening section 19.

[0071] Specifically, the material reduction groove 107 effectively reduces the material usage of the heightening section 19, avoiding unnecessary material waste while ensuring the basic structural strength and function of the heightening section 19, thereby reducing production costs. Simultaneously, due to the reduction in local thickness, the overall weight of the heightening section 19 is reduced, contributing to the product's lightweight design and facilitating subsequent assembly, handling, and use. The spacing of the material reduction groove 107 also optimizes the stress distribution of the heightening section 19, preventing localized stress concentration caused by material redundancy, further enhancing the structure's stability and durability.

[0072] Furthermore, the material reduction groove 107 simplifies the processing of the heightening section 19, reduces processing difficulty, and improves production efficiency. Overall, this technical solution, by rationally arranging the material reduction groove 107 on the heightening section 19, achieves both material savings and cost reduction, while ensuring structural strength and functionality, enhancing the product's portability and practicality, and achieving the expected technical effects.

[0073] The retaining ring 40 does not exceed the opening of the second deformation cavity, thereby preventing the retaining ring 40 from blocking external gas from entering the second deformation cavity. The raised part 19 is further connected to the second connecting part 32 to improve the installation stability of the second sealing ring 30.

[0074] This technical solution effectively solves the technical problem in the prior art where the structure of the fixing ring 40 easily blocks external gas from entering the second deformation cavity, causing the second sealing ring 30 to fail to deform properly and affecting the sealing effect, by limiting the size of the fixing ring 40 to not exceed the opening of the second deformation cavity. By ensuring that the fixing ring 40 does not prevent external gas from entering the second deformation cavity, external gas can smoothly enter the second deformation cavity, thereby ensuring that the second sealing ring 30 can deform in a timely manner according to the gas pressure, achieving a more reliable sealing effect.

[0075] Furthermore, the heightening portion 19 is further connected to the second connecting portion 32, improving the installation stability of the second sealing ring 30 and overcoming the problems of easy displacement of the sealing ring installation position and insecure sealing in the existing structure. Through the above structural design, the heightening portion 19 and the second connecting portion 32 form a stable support and positioning, effectively ensuring the accurate position and tight sealing of the second sealing ring 30 during use.

[0076] In summary, by optimizing the structural layout of the fixing ring 40 and the heightening part 19, this technical solution not only avoids the fixing ring 40 from blocking gas from entering the second deformation cavity, thus improving the responsiveness and sealing reliability of the sealing ring, but also enhances the installation stability of the second sealing ring 30, thereby achieving the technical effects of improved sealing performance and structural reliability.

[0077] The second sealing ring 30 includes a second fixing part 31, a second connecting part 32 and a second sealing part 33 connected in sequence. The second fixing part 31 and the second sealing part 33 form a second deformation cavity at an interval. The two opposite ends of the second fixing part 31 are respectively connected to the fixing ring 40 and the raising part. The second sealing part 33 is used to contact the second Mason jar.

[0078] In this embodiment, the second sealing ring 30 includes a second fixing part 31, a second connecting part 32, and a second sealing part 33 connected in sequence. The second fixing part 31 and the second sealing part 33 are spaced apart to form a second deformation cavity. The pressure inside the second deformation cavity is lower than the external pressure. Therefore, during use, external gas will enter the second deformation cavity, thereby applying pressure to the second sealing part 33, allowing the second sealing part 33 to fit more tightly against the second Mason jar, achieving a reliable sealing effect. The opposite ends of the second fixing part 31 are connected to the fixing ring 40 and the raising part, respectively, effectively ensuring the installation position and structural stability of the second sealing ring 30 and preventing the sealing ring from shifting under pressure. In addition, the second sealing part 33 is specifically designed for direct contact with the second Mason jar, improving the matching and airtightness of the sealing area.

[0079] The above technical solution solves the problems in the prior art where the second sealing ring 30 is prone to displacement, incomplete sealing, or unstable sealing performance under pressure. The structural design that utilizes external gas to apply pressure to the second sealing part 33 improves the tightness of the fit between the sealing part and the tank body, thereby enhancing the overall sealing performance and preventing gas leakage. Simultaneously, the second deformation cavity allows the sealing ring to absorb external pressure through deformation under pressure, further improving the reliability of the seal. Overall, this technical solution achieves the technical effects of improving the sealing effect of the second sealing ring 30, ensuring sealing reliability and structural stability, and significantly enhancing the sealing performance and durability of the product in practical applications.

[0080] The second sealing part 33 has a second chamfer 34 on its outer peripheral surface away from the second connecting part 32 and away from the second deformation cavity 35. The second chamfer 34 can be a rounded corner or a beveled corner.

[0081] Specifically, the second chamfer 34 significantly reduces the sharpness of this part. Whether a rounded or beveled corner is used, it reduces scratches, squeezing, or stress concentration caused by the end edge contacting other components during assembly, thereby reducing the risk of seal damage. At the same time, the second chamfer 34 helps guide the second Mason flask to be smoothly inserted into the corresponding installation position, improving the smoothness and efficiency of the assembly process and avoiding assembly difficulties caused by end jamming.

[0082] In addition, the application of the second chamfer 34 can improve the structural integrity and durability of the product, prevent the end cracks of the second sealing part 33 from expanding due to long-term use, and effectively extend the service life of the product.

[0083] The first retaining ring 12 has a first step 108 on its outer peripheral surface away from the partition plate 11 and away from the first working groove 101. The suction machine and the first step 108 are matched to ensure that the suction machine 200 is directly opposite the vent 103.

[0084] In this embodiment, a first step 108 is provided at the end of the first retaining ring 12 away from the partition plate 11, and this step is located on the outer peripheral surface away from the first working groove 101. The vacuum pump is matched with the first step 108 to ensure that the vacuum pump is always aligned with the vent hole 103 during installation or operation. Through the above structural design, the problems of inaccurate positioning of the vacuum pump, resulting in reduced vacuuming efficiency or misalignment of the vent hole 103 in the prior art are effectively solved. Specifically, the first step 108, as a limiting and positioning element, can provide a clear installation reference for the vacuum pump, preventing the vacuum pump from shifting or misaligning during use, and ensuring precise alignment between the vacuum pump and the vent hole 103. Thus, the technical effects of improving the positioning accuracy of the vacuum pump, enhancing vacuuming efficiency, reducing assembly difficulty, and improving product performance are achieved. Specifically, the first step 108, in conjunction with the limiting mechanism of the vacuum pump, ensures precise alignment between the vacuum pump and the vent 103. This prevents misalignment caused by assembly errors, guarantees smooth airflow, improves vacuum efficiency, simplifies the installation process, reduces human error in positioning, and enhances assembly consistency and reliability. Furthermore, by preventing misalignment between the vacuum pump and the vent 103, leakage and energy consumption are reduced, resulting in an overall improvement in product performance and lifespan. Therefore, this embodiment effectively solves the problems of inaccurate vacuum pump positioning or low vacuum efficiency, achieving reliable alignment between the vacuum pump and the vent 103, thereby improving vacuum efficiency and product performance.

[0085] The second retaining ring 13 has a second step 109 on its outer peripheral surface away from the partition plate 11 and away from the second working groove 102. The suction machine and the second step 109 are matched to ensure that the suction machine 200 is directly opposite the vent 103.

[0086] In this embodiment, a second step 109 is provided at the end of the second retaining ring 13 away from the partition plate 11, and this step is located on the outer peripheral surface away from the second working groove 102. The vacuum pump is matched with the second step 109 to ensure that the vacuum pump is always aligned with the vent hole 103 during installation or operation. Through the above structural design, the problems of inaccurate positioning of the vacuum pump, resulting in reduced vacuuming efficiency or misalignment of the vent hole 103 in the prior art are effectively solved. Specifically, the second step 109, as a limiting and positioning element, can provide a clear installation reference for the vacuum pump, preventing the vacuum pump from shifting or misaligning during use, and ensuring precise alignment between the vacuum pump and the vent hole 103. Thus, the technical effects of improving the positioning accuracy of the vacuum pump, enhancing vacuuming efficiency, reducing assembly difficulty, and improving product performance are achieved. Specifically, the second step 109, in conjunction with the limiting mechanism of the vacuum pump, ensures precise alignment between the vacuum pump and the vent 103. This prevents misalignment caused by assembly errors, guarantees smooth airflow, improves vacuum efficiency, simplifies the installation process, reduces human error in positioning, and enhances assembly consistency and reliability. Furthermore, by preventing misalignment between the vacuum pump and the vent 103, leakage and energy consumption are reduced, resulting in an overall improvement in product performance and lifespan. Therefore, this embodiment effectively solves the problems of inaccurate vacuum pump positioning or low vacuum efficiency, achieving reliable alignment between the vacuum pump and the vent 103, thereby improving vacuum efficiency and product performance.
