Description

Technical Field

[0001] This utility model relates to the technical field of dishwasher body sealing cover, and more specifically, to a sealing cover. Background Technology

[0002] In the daily use of dishwashers, the lid is crucial for ensuring the stability of the internal environment of the equipment and preventing liquid leakage and the entry of external impurities. The sealing performance of the lid structure used in some dishwashers on the market has certain limitations in sealing design. A good sealing effect can not only ensure that the dishwasher can effectively prevent water or other cleaning liquids from leaking during operation and avoid damage to the surrounding environment, but also maintain the stability of the internal pressure and temperature of the equipment, ensuring the washing effect.

[0003] A search revealed that patent publication number CN203111685U discloses a combined structure of a bottle cap and bottle mouth. The bottle mouth has an internal thread structure, and the bottle cap has an external thread structure. The bottle mouth and bottle cap are fixed and locked together by the threaded structure. The bottle cap and bottle mouth have two seals. The first seal is the contact surface between the bottle cap and the inner edge and end face of the bottle mouth. The product provides a good seal and can be filled with cold, hot, and carbonated beverages. After filling, it can be stored in a low-temperature environment. It eliminates the food safety hazards caused by mold growth at the bottle mouth and insect eggs infesting the threads. The double seal solves the problem of beverage spoilage caused by poor sealing due to bumps, drops, or impacts. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] When the connection between the lid and the dishwasher body is not tight enough, it is prone to loosening after long-term use or under external force, resulting in a decrease in sealing performance. Some lids are prone to aging and deformation when facing the high temperature, high pressure and frequent mechanical vibration environment inside the dishwasher, which in turn affects the sealing effect. Some dishwasher lids have cumbersome opening and closing procedures that require tools to disassemble, or unreasonable thread design makes tightening and loosening difficult, increasing the workload of operators and reducing work efficiency.

[0005] Therefore, a sealing cap is proposed to address the above issues. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sealing cap to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: It includes a base body, the outer side of which is provided with an external thread section. The thread specifications of the external thread section are strictly designed, with uniform thread spacing and depth. A snap-fit ​​block is also provided on the outer side of the base body via a snap-fit ​​mechanism. The top of the base body is open, and the edge of the opening is smoothly treated. An annular retainer is threadedly engaged on the outer side of the base body. An internal thread section is provided inside the snap-fit ​​block. When the annular retainer is installed on the outer side of the base body, the external thread section and the internal thread section can achieve threaded engagement. Annular blocks are evenly distributed on the top of the annular retainer, and the top of the annular blocks and the top of the annular retainer are integrally formed. An internal retainer block is provided inside the base body. An inner ring is detachably installed inside the base body. An inner cover plate is fixedly provided on the top of the inner ring. A snap-fit ​​interface is provided at the edge of the inner cover plate. An outer cover plate is also placed on the outer side of the base body.

[0008] Preferably, a specific distance is left between the opening and the external thread section, so that the threads can be fully engaged during the tightening process, and the opening and the snap block are on the same reference plane.

[0009] Preferably, a support plate is uniformly and securely installed on the outer side of the annular card holder, and the support plates are arranged in an orderly manner with equal spacing along the outer circumference of the annular card holder.

[0010] Preferably, a support ring is securely fixed to the outer side of the inner ring, the support ring is tightly fitted to the inner ring, and a sealing ring is provided inside the support ring, the shape of which is adapted to the internal space of the support ring.

[0011] Preferably, the inner ring is uniformly provided with partitions, which are arranged in an orderly manner at equal intervals along the circumference of the inner ring, and each partition is tightly connected to the inner wall of the inner ring.

[0012] Preferably, the top of the outer cover is provided with an anti-detachment snap ring, which is an annular protrusion. The anti-detachment snap ring is snapped into the snap interface at the edge of the inner cover. The shape of the snap interface is adapted to the anti-detachment snap ring. When the two are snapped together, the anti-detachment snap ring can be firmly embedded in the snap interface. Through this snapping method, the seat body is tightly connected to the outer cover with the help of the inner ring, the inner cover component and the outer cover.

[0013] Preferably, the outer cover is located directly above the annular card holder, and the two have a clear relative relationship in spatial layout, and the annular card holder and the outer cover are kept in a state of not contacting each other.

[0014] Preferably, a triangular block is provided inside the bottom of the base, the triangular block is embedded in the bottom of the base, and a through hole is provided on the upper side of the triangular block.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] Compared with existing technologies, this sealing cap achieves a precise threaded connection through the strictly designed uniform external thread section on the seat and the internal thread section in the snap block. At the same time, the sealing ring adapted inside the outer support ring of the inner ring can fit tightly against the relevant components, effectively preventing the entry of external air, moisture and impurities, thus greatly improving the sealing performance.

[0017] Compared to existing technologies, this sealing cap offers greater ease of operation. A specific distance between the opening and the external thread section ensures full thread engagement, and the opening and the snap-fit ​​block are on the same reference plane, facilitating quick and accurate installation and tightening by the operator. The anti-disengagement snap-fit ​​ring on the top of the outer cover plate and the snap-fit ​​interface on the edge of the inner cover plate fit together securely, allowing the seat to be tightly connected to the outer cover plate via the inner ring and inner cover plate. The opening and closing process is simple and efficient, reducing the operator's workload and improving work efficiency.

[0018] To address the issue of decreased sealing performance after repeated opening, the components of this sealing cover are securely connected. For example, the support plates arranged evenly and at equal intervals on the outer side of the annular base enhance the overall structural stability. Meanwhile, the triangular blocks embedded in the bottom of the base and providing through holes help balance internal and external pressure, reducing deformation and wear of components caused by pressure differences. Furthermore, the tight fit design of each component reduces the impact of repeated opening on sealing performance, extends the service life of the salt water dishwasher, and lowers operating costs.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] As attached Figures 1 to 5 The sealing cover shown includes a base 1. The outer side of the base 1 is provided with an external thread section 2. The thread specification of the external thread section 2 is strictly designed, and the thread spacing and depth are uniform. The outer side of the base 1 is also provided with a snap-fit ​​block 3. The top of the base 1 is provided with an opening 4. The edge of the opening 4 is smoothed. The outer side of the base 1 is threadedly connected to an annular retainer 5. The snap-fit ​​block 3 is provided with an internal thread section 6. When the annular retainer 5 is installed on the outer side of the base 1, the external thread section 2 and the internal thread section 6 can achieve threaded engagement. The top of the annular retainer 5 is uniformly provided with annular blocks 7. The top of the annular blocks 7 and the top of the annular retainer 5 are integral structures. The inside of the base 1 is provided with an inner retainer block 9. The inside of the base 1 is detachably installed with an inner ring 10. The top of the inner ring 10 is fixedly provided with an inner cover plate 14. The edge of the inner cover plate 14 is provided with a snap-fit ​​interface 15. An outer cover plate 16 is also placed on the outer side of the base 1.

[0028] Among them, the thread specification of the outer external thread section 2 of the seat body 1 is strictly designed, with uniform spacing and depth, forming a double thread engagement structure with the inner internal thread section 6 of the snap block 3. This design makes the ring-shaped snap block 5 tightly connected to the seat body 1. Compared with the ordinary single thread sealing cover, the sealing effect is significantly enhanced, effectively preventing brine leakage, reducing the entry of external air and impurities, and ensuring the purity and quality of brine.

[0029] The top opening 4 of the base 1 has a smooth edge, reducing friction with the sealing components during installation or disassembly, making operation smoother. The annular retainer 5 is threaded into the base 1, requiring no tools and can be manually rotated, significantly saving time and labor costs. It is especially suitable for scenarios where the salt water dishwasher body is frequently opened and closed. The annular retainer 5 has evenly distributed and integrally formed annular blocks 7 on its top, enhancing the overall strength of the annular retainer 5 and making it less prone to deformation and damage when subjected to pressure and vibration. The inner retainer 9 of the base 1 fits tightly with the detachable inner ring 1, ensuring a stable installation and facilitating cleaning, replacement, and maintenance, thus extending the service life of the sealing cover. The inner cover plate 14 is made visible, improving the user experience. The inner cover plate 14 and the outer cover plate 16 are connected by an inverted ring, making installation convenient and less prone to damage, reducing the rotational force of the cover and making rotation easy. Previously, the inner and outer covers were integrated, making rotation difficult.

[0030] Example 2

[0031] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details:

[0032] As a preferred embodiment, a specific distance is left between the opening 4 and the external thread section 2. During the tightening process, the threads are fully engaged, preventing deformation of the opening and avoiding damage to the threads or loose connection due to insufficient space. This effectively improves the stability and sealing performance of the connection between the sealing cover and the dishwasher body. The opening 4 and the snap-fit ​​block 3 are on the same reference plane, which ensures that the relative positions of each component are accurate during installation, facilitates precise positioning, prevents poor sealing or installation difficulties due to positional deviations, and improves assembly efficiency and sealing effect. Similarly, the snap-fit ​​and thread section on the base are also on the same reference plane. This design makes the overall product thickness more consistent and stable after shrinkage. The segmented design of the snap-fit ​​and thread section in products on the market results in inconsistent product thickness, which is prone to stress shrinkage deformation.

[0033] As a preferred embodiment, a support plate 8 is evenly and stably installed on the outer side of the annular bracket 5, which can evenly distribute the external force on the annular bracket 5, avoid excessive local stress and deformation and damage, and enhance the overall structural strength of the annular bracket 5. The support plates 8 are arranged and installed in an orderly manner with equal spacing along the outer circumference of the annular bracket 5, which can make the force on the annular bracket 5 more balanced, ensure its installation stability, and facilitate standardized production and installation, thereby improving production efficiency and assembly accuracy.

[0034] In a preferred embodiment, a support ring 12 is securely fixed to the outer side of the inner ring 10, providing stable support for the inner ring 10, enhancing the overall structural strength of the inner ring 10, and preventing deformation or displacement during use. The support ring 12 fits tightly with the inner ring 10, effectively reducing gaps between them, preventing liquid leakage, and improving sealing performance. A sealing ring 13 is provided inside the support ring 12. The shape of the sealing ring 13 is adapted to the internal space of the support ring 12, which can tightly fill the gaps, further enhancing the sealing effect, preventing leakage of liquids such as salt water, and ensuring the normal operation of the sealing cap.

[0035] In a preferred embodiment, partitions 11 are uniformly arranged inside the inner ring 10, which can reasonably divide the internal space of the inner ring 10, making the internal structure layout more regular and facilitating the partitioning of different components or functions. These partitions 11 are arranged in an orderly manner along the circumference of the inner ring 10 at equal intervals, which can ensure that the internal force of the inner ring 10 is uniform, avoid deformation or damage due to uneven local force, and extend the service life of the inner ring 10. Each partition 11 is tightly connected to the inner wall of the inner ring 10, which enhances the stability of the overall structure and can effectively prevent liquid leakage between the partition 11 and the inner wall, thus improving the sealing performance.

[0036] In a preferred embodiment, the top of the outer cover plate 16 is provided with an anti-detachment snap-fit ​​ring 17, which provides a stable structural foundation for snap-fit ​​and enhances the stability during snap-fit. The anti-detachment snap-fit ​​ring 17 is annularly protruding and is snap-fitted with the snap-fit ​​interface 15 at the edge of the inner cover plate 14. The shape of the snap-fit ​​interface 15 is adapted to the anti-detachment snap-fit ​​ring 17, so that the connection between the two is accurate and installation errors are reduced. When the two are snapped together, the anti-detachment snap-fit ​​ring 17 can be firmly embedded in the snap-fit ​​interface 15, which can effectively prevent the outer cover plate 16 from falling off and ensure the firmness of the connection. Through this snap-fit ​​method, the seat 1 is tightly connected to the outer cover plate 16 with the inner ring 10 and the inner cover plate 14 components, which improves the overall sealing performance and structural integrity.

[0037] In a preferred embodiment, the outer cover 16 is located directly above the annular bracket 5. This clear spatial layout facilitates the design and assembly of the overall structure, ensures accurate installation of each component, and improves assembly efficiency. The two components have a clear relative relationship in their spatial layout, which is beneficial for positioning the outer cover 16 and avoids installation deviations that could affect the sealing performance. Furthermore, the annular bracket 5 and the outer cover 16 remain in a non-contact state, which can effectively prevent friction and wear caused by contact, extend the service life of the components, and avoid uneven force on the outer cover 16 due to contact, ensuring its installation stability and thus improving the overall sealing performance and reliability of the sealing cover.

[0038] In a preferred embodiment, a triangular block 18 is provided inside the bottom of the seat body 1. The triangular block 18 is embedded in the bottom of the seat body 1. The triangular block 18 can enhance the structural strength of the bottom of the seat body 1, effectively resist external pressure and impact, prevent the bottom of the seat body 1 from deforming and being damaged, and improve the overall stability. A through hole 19 is provided on the upper side of the triangular block 1, which can play a role in ventilation, balance the internal and external pressure of the seat body 1, and avoid structural damage due to pressure difference. At the same time, the through hole 19 can also reduce the weight of the seat body 1 to a certain extent, save material costs, and does not affect its sealing performance and normal use.

[0039] The working process of this utility model is as follows: In use, first, prepare all components, including the base 1, annular retainer 5, inner ring 10, and outer cover 16. Next, thread the annular retainer 5 onto the outside of the base 1, using the external thread section 2 and the internal thread section 6 inside the snap-fit ​​block 3 to achieve threaded engagement, ensuring proper installation. Then, detachably install the inner ring 10 into the base 1, so that the inner ring 10 engages with the internal snap-fit ​​block 9 inside the base 1. At this time, the snap-fit ​​interface 15 on the edge of the inner cover 14 at the top of the inner ring 10 is in a ready-to-engage state. Finally, place the outer cover 16 in a suitable position, ensuring its top is protected against... The release ring 17 engages with the locking interface 15 at the edge of the inner cover plate 14. Because the locking interface 15 and the anti-release locking ring 17 are shaped to match, the anti-release locking ring 17 is firmly embedded in the locking interface 15, so that the seat 1 is tightly connected to the outer cover plate 16 with the help of the inner ring 10 and the inner cover plate 14. This ensures that the outer cover plate 16 is located directly above the annular locking seat 5 and that the annular locking seat 5 and the outer cover plate 16 do not contact each other. Then, a specific distance is left between the opening 4 and the external thread section 2, so that the threads can fully engage during the tightening process. The opening 4 and the locking block 3 are on the same reference plane. This completes the assembly and preparation of the sealing cover, which can then be put into use.
