Description

Technical Field

[0001] This utility model relates to the technical field of vacuum cleaner accessories, specifically to environmentally friendly collection bag sealing cards. Background Technology

[0002] As people's living standards improve, their requirements for the cleanliness of their living environment are also increasing. Vacuum cleaners and other cleaning equipment are being used more and more widely in homes and public places. In order to improve the convenience of use and cleaning efficiency, most existing vacuum cleaners and other cleaning equipment are equipped with base stations. Base stations have multiple functions, the most important of which are charging vacuum cleaners and other equipment and collecting dust.

[0003] Existing base stations generally consist of a dust collection chamber and a suction component. After the vacuum cleaner finishes cleaning, it is placed on the base station, and the base station's suction component starts working. Through strong suction, it draws the debris from the vacuum cleaner's dust cup into the dust collection chamber, achieving the purpose of centralized collection of debris. This dust collection method avoids the dust problem that may occur when users manually empty the dust cup, making it both convenient and hygienic.

[0004] To facilitate centralized processing of collected waste, collection bags are usually installed inside the dust collection chamber. The collection bags can effectively hold the waste, and when the waste is full, the user only needs to replace the collection bag, without the need for complicated cleaning of the dust collection chamber.

[0005] However, the collection bags currently on the market have some shortcomings. The connection between the existing collection bags and the base station's mainboard is not stable. In actual use, due to the large suction and vibration generated when the suction component is working, the unstable connection can easily cause the collection bag to shift or even fall off. Once the collection bag shifts or falls off, the garbage may leak into other parts of the dust collection chamber, which not only increases the difficulty of cleaning but may also affect the normal operation of the base station and reduce the dust collection effect. In addition, the loose connection between the collection bag and the mainboard may also lead to poor sealing, causing some dust to escape during the suction process, resulting in secondary pollution, which violates the original intention of environmental protection.

[0006] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0007] Regarding the aforementioned technical issue of unstable connection between the existing dust collection bag installed in the dust collection chamber and the mainboard, which facilitates waste collection and centralized treatment, this paper addresses the problem of the existing dust collection bag being unstable in connection with the mainboard.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] An environmentally friendly collection bag sealing card includes a main board with a first vent on the main board. The front of the main board has a sealing protrusion that corresponds to the first vent and is connected to the collection bag. The sealing protrusion and the opening of the collection bag are fixed together by ultrasonic process to form a sealed connection.

[0010] As described above, the sealing card for the environmentally friendly collection bag has multiple annular welded protrusions arranged concentrically around the center of the first vent.

[0011] As described above, the environmentally friendly collection bag sealing card has a movable plate slidably connected to the back of the main board. The movable plate is provided with a second vent corresponding to the first vent. When the movable plate slides on the main board until the second vent and the first vent are aligned, the garbage can enter the collection bag sequentially through the second vent and the first vent.

[0012] As described above, the environmentally friendly collection bag sealing card has two spaced slide rails on the back of the main board, and each slide rail has a groove on one side for inserting a movable plate and constraining the sliding of the movable plate.

[0013] As described above, each of the slide rail portions includes a main board protrusion on one side of the main board and a slide groove protrusion on the side of the main board protrusion closer to the main board. The slide groove protrusion is at a certain distance from the main board to form the slide groove.

[0014] As described above, the environmentally friendly collection bag sealing card has multiple groove protrusions, which are spaced apart along the length of the main board protrusions.

[0015] As described above, in the environmentally friendly collection bag sealing card, each of the main board protrusions has a connecting block on the side wall that is relatively far from the slide groove protrusion.

[0016] As described above, the environmentally friendly collection bag sealing card also includes a sealing component between the back of the main board and the movable plate. When the movable plate slides on the main board until the second vent and the first vent are completely misaligned, the sealing component and the body of the movable plate are sealed.

[0017] The sealing assembly of the environmentally friendly collection bag sealing card as described above includes a sealing ring disposed around the outside of the first vent.

[0018] As described above, the environmentally friendly collection bag sealing card has an assembly groove on the back of the main board and an assembly protrusion corresponding to the assembly groove on the sealing ring.

[0019] The beneficial effects of this utility model are as follows:

[0020] This utility model relates to the technical field of vacuum cleaner accessories, specifically an environmentally friendly collection bag sealing card. It includes a main board with a first vent. The front of the main board has a sealing protrusion corresponding to the first vent and connected to the collection bag. The sealing protrusion and the opening of the collection bag are sealed together using an ultrasonic process. When the vacuum cleaner's suction assembly starts working, a negative pressure environment is created in the dust collection chamber. After the waste is sucked from the vacuum cleaner's dust cup into the dust collection chamber, it enters the collection bag connected to the sealing protrusion through the first vent on the main board. Because the sealing protrusion and the opening of the collection bag are sealed together using an ultrasonic process, during suction, it effectively prevents waste and dust from leaking out from the connection between the collection bag and the main board. The ultrasonic process causes the materials of the sealing protrusion and the opening of the collection bag to fuse together under high-frequency vibration, forming a tight bond.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] like Figures 1 to 6As shown, the environmentally friendly collection bag sealing card of this embodiment includes a main board 1, on which a first vent 11 is provided. The front of the main board 1 is provided with a sealing protrusion 12 corresponding to the first vent 11 and connected to the collection bag. The sealing protrusion 12 and the opening of the collection bag are fixed together by ultrasonic process to form a sealed connection.

[0030] When the vacuum cleaner base station's suction component starts working, it creates a negative pressure environment in the dust collection chamber. After the debris is sucked into the dust collection chamber from the vacuum cleaner's dust cup, it enters the collection bag connected to the sealing protrusion through the first vent on the main board. Because the sealing protrusion and the bag opening are fixed together by ultrasonic technology to form a sealed connection, it can effectively prevent debris and dust from leaking out from the connection between the collection bag and the main board during the suction process. The ultrasonic technology causes the materials of the sealing protrusion and the bag opening to fuse together under high-frequency vibration, forming a tight bond, ensuring that gas and debris can only enter the collection bag through the first vent, thus achieving an efficient debris collection process.

[0031] The ultrasonic process creates a sealed connection that greatly improves the sealing between the collection bag and the main board. Compared with traditional connection methods, it can effectively prevent dust from escaping through gaps during collection and storage, reducing the possibility of secondary pollution and meeting environmental protection requirements.

[0032] The tight seal allows the suction force generated by the suction component to act more effectively inside the collection bag, smoothly sucking the garbage into the bag. After being sealed using ultrasonic technology, the suction force of the suction component can be fully utilized, improving dust collection efficiency.

[0033] When the suction component of the base station is working, it generates a large suction force and vibration. The connection formed by the ultrasonic process can firmly connect the collection bag to the main board, resist the influence of these external forces, and ensure that the collection bag will not shift or fall off due to suction and vibration. This avoids problems such as garbage leakage and difficulty in cleaning the dust collection chamber caused by the displacement of the collection bag, and ensures the normal operation and service life of the base station.

[0034] A robust connection reduces relative movement and friction between the collection bag and the mainboard, lowering the risk of component damage due to a loose connection. This extends the lifespan of both the collection bag and the mainboard, reduces the frequency of component replacement, and lowers operating costs.

[0035] Thanks to its excellent sealing, the collection bag can be easily replaced and disposed of. When the collection bag is full of trash, users can directly remove the mainboard from the vacuum cleaner base for cleaning or replacement.

[0036] like Figures 1 to 6As shown, the top surface of the sealing protrusion 12 in this embodiment is provided with a plurality of annular welded protrusions 13 arranged in concentric circles with the center of the first vent 11 as the center.

[0037] When the sealing protrusion 12 is fixed to the bag opening of the collection bag using ultrasonic technology, the ultrasonic equipment will generate high-frequency vibration. When the ultrasonic vibration is transmitted to the sealing protrusion 12, the annular welding protrusion 13 will first contact the bag opening of the collection bag. Due to the shape characteristics of the annular welding protrusion 13, under the action of ultrasonic vibration, the part of it that contacts the material of the bag opening (usually the annular welding groove corresponding to the annular welding protrusion 13) will generate heat, which will quickly soften the material and fuse it together. The concentric arrangement with the center of the first vent 11 as the center can ensure that the heat is evenly distributed on the contact surface between the sealing protrusion 12 and the bag opening of the collection bag during the ultrasonic welding process, so that the entire contact surface can achieve good welding, thereby forming a sealed connection. In this way, when the vacuum cleaner base station is working, garbage and dust can only enter the collection bag through the first vent 11 and will not leak from the sealed connection.

[0038] Specifically, multiple annular welded protrusions 13 form a multi-layered sealing structure. Even if a minor defect occurs in the seal of one of the annular welded protrusions 13, the other annular welded protrusions 13 can still function as a seal, greatly reducing the risk of dust and garbage leakage. This is similar to setting up multiple layers of protection for the connection between the collection bag and the mainboard, improving the overall sealing performance and reliability.

[0039] Preferably, the concentric circle arrangement allows the sealing pressure to be applied evenly to all parts of the bag opening during ultrasonic welding. This design avoids poor sealing caused by uneven local pressure, ensuring a tight connection throughout the sealing area and further improving the sealing effect.

[0040] The annular welding protrusion 13 increases the actual welding area between the sealing protrusion 12 and the bag opening. During ultrasonic welding, a larger welding area means more material fusion, thus increasing the weld strength. This makes the connection between the bag and the main board more robust, able to withstand greater suction and external forces, and reduces the possibility of the bag falling off or the connection point being damaged during use.

[0041] When the vacuum cleaner base station is working, the collection bag is subjected to various external forces such as suction and vibration. The concentrically arranged annular welded protrusions 13 can disperse these external forces to multiple annular structures, avoiding stress concentration at a certain point or area, thereby improving the fatigue resistance of the connection parts and extending the service life.

[0042] Preferably, the design of concentric circles with the center of the first vent 11 as the center has a certain regularity, which facilitates precise control in the ultrasonic welding process. The ultrasonic equipment can more accurately position and apply energy, so that each annular welding protrusion 13 can achieve the ideal welding effect, reducing the problem of unstable welding quality caused by process deviation.

[0043] The design of the annular welding protrusion 13 makes the welding process more stable and reliable, reduces the defect rate and improves production efficiency during production. At the same time, this regular design also facilitates the operation of automated production equipment, which is conducive to large-scale production and reduces production costs.

[0044] like Figures 1 to 6 As shown, a movable plate 2 is slidably connected to the back of the main board 1 in this embodiment. The movable plate 2 is provided with a second vent 21 corresponding to the first vent 11. When the movable plate 2 slides on the main board 1 until the second vent 21 and the first vent 11 are connected, the garbage can enter the collection bag in sequence through the second vent 21 and the first vent 11.

[0045] Specifically, the main board 1 and the movable plate 2 are connected by a sliding connection. The movable plate 2 can slide along a specific track or path on the back of the main board 1. The second vent 21 on the movable plate 2 is designed to correspond to the first vent 11 on the main board 1. When it is necessary to let the garbage into the collection bag, the movable plate 2 is pushed to slide on the main board 1, so that the second vent 21 and the first vent 11 gradually align and complete the docking.

[0046] Once the second vent 21 and the first vent 11 are connected, a continuous channel is formed. When the vacuum cleaner base station is working, the suction generated by the fan is used to suck up the garbage from the outside. The garbage will pass through the second vent 21 and the first vent 11 in sequence and finally enter the collection bag connected to the first vent 11 to realize the garbage collection function. When garbage collection is not needed, the second vent 21 and the first vent 11 can be staggered by driving the movable plate 2 to block the garbage from entering the collection bag. The connection and staggering of the second vent 21 and the first vent 11 can be controlled by sliding the movable plate 2, which can flexibly open or close the garbage entering the collection bag according to actual needs.

[0047] When the movable plate 2 slides to a position where the second vent 21 and the first vent 11 are misaligned, the movable plate 2 can play a certain sealing role, reducing the leakage of garbage and dust inside the collection bag.

[0048] When the second vent 21 and the first vent 11 are connected, a tight connection is formed, reducing suction loss, improving the efficiency of garbage collection, and further reducing the possibility of garbage leakage at the connection point.

[0049] The movable plate 2 can be slid off from the main plate 1 or slid to a position that is easy to operate. This allows users to more easily clean the first vent 11 and the second vent 21 when the vent needs to be cleaned, remove debris that may block the vent, and ensure that the garbage collection channel is unobstructed.

[0050] like Figures 1 to 6 As shown, the back of the main board 1 in this embodiment is provided with two spaced slide rails 14, and each slide rail 14 is provided with a groove 15 on one side for inserting the movable plate 2 and constraining the movable plate 2 to slide.

[0051] Specifically, during the assembly process, the movable plate 2 is inserted into the slide groove 15 on one side of the slide rail 14 on the back of the main board 1. The size and shape of the slide groove 15 are adapted to the edge of the movable plate 2, so that the movable plate 2 can be accurately embedded in the slide groove 15, and the movable plate 2 is initially positioned on the main board 1.

[0052] The slide groove 15 constrains the movable plate 2. Since the two side walls of the slide groove 15 restrict the movement of the movable plate 2 in the direction perpendicular to the sliding direction, the movable plate 2 can only slide along the extension direction of the slide groove 15 on the back of the main plate 1. When it is necessary to adjust the position of the movable plate 2 so that the second vent 21 and the first vent 11 are aligned or staggered, the movable plate 2 is pushed by an external force, and the movable plate 2 will slide linearly along a predetermined path under the constraint of the slide groove 15.

[0053] The two spaced slide rails 14 and their grooves 15 provide precise guidance for the sliding of the movable plate 2. Under the restriction of the grooves 15, the movable plate 2 can only slide in a straight line in a specific direction, avoiding deviation, shaking or twisting of the movable plate 2 during the sliding process. This ensures that the movable plate 2 can accurately reach the predetermined position and achieve precise docking or offset between the second vent 21 and the first vent 11, thereby ensuring the normal opening and closing of the garbage collection channel.

[0054] The inner wall of the slide groove 15 is reasonably designed and processed, and the surface is relatively smooth, which can reduce the friction between the movable plate 2 and the slide groove 15. At the same time, the constraint effect of the slide groove 15 on the movable plate 2 makes the movable plate 2 more evenly stressed during the sliding process, further reducing the probability of jamming and ensuring the smoothness of the sliding of the movable plate 2.

[0055] The two spaced slide rails 14 share the weight of the movable plate 2 and the force generated during sliding. When the movable plate 2 is pushed by an external force, the force is transmitted through the movable plate 2 to the two slide grooves 15 and distributed by the two slide rails 14. This avoids structural damage caused by excessive local stress. This method of distributing the force improves the load-bearing capacity and reliability of the entire structure and extends the service life of the product.

[0056] The groove 15 not only restricts the movement of the movable plate 2 in the sliding direction, but also provides a certain degree of support for the movable plate 2, preventing deformation of the movable plate 2 during use. In particular, when the movable plate 2 is subjected to lateral force or uneven pressure, the groove 15 can effectively resist these external forces, maintain the shape and dimensional stability of the movable plate 2, and ensure its normal sliding function.

[0057] The assembly method of inserting the movable plate 2 into the slide 15 is simple and easy, requiring no complicated tools or operating steps. During the production process, it can improve assembly efficiency and reduce production costs. At the same time, this simple assembly method also makes the product more convenient to transport and install, reducing the probability of failure caused by improper assembly.

[0058] If the movable plate 2 or the slide rail 14 malfunctions or needs cleaning, since the movable plate 2 slides by being inserted into the slide groove 15, the user or maintenance personnel can easily remove the movable plate 2 from the slide groove 15 and clean, repair or replace the movable plate 2 and the slide groove 15 separately, reducing the difficulty and cost of maintenance.

[0059] like Figures 1 to 6 As shown, each of the slide rail portions 14 in this embodiment includes a motherboard protrusion 141 disposed on one side of the motherboard 1 and a slide groove protrusion 142 disposed on the side of the motherboard protrusion 141 close to the motherboard 1. The slide groove protrusion 142 is at a certain distance from the motherboard 1 to form the slide groove 15.

[0060] Specifically, the motherboard bump 141 protrudes from one side of the motherboard 1, while the sliding groove protrusion 142 is located on the side of the motherboard bump 141 close to the motherboard 1, and there is a certain distance between them. This distance constitutes the sliding groove 15 for the movable plate 2 to be inserted and slid. When the movable plate 2 is inserted, it is within the space defined by the sliding groove protrusion 142 and the motherboard 1.

[0061] After the movable plate 2 is inserted into the slide groove 15, the slide groove protrusion 142 restricts the upward disengagement path of the movable plate 2. The main plate 1 serves as the support plane for the sliding of the movable plate 2. When it is necessary to adjust the position of the movable plate 2, an external force is applied to push the movable plate 2, and the movable plate 2 will slide along the direction defined by the main plate 1 and the slide groove protrusion 142, thereby realizing the cooperative action with related components (such as vents) on the main plate 1.

[0062] The movable plate 2 can be easily inserted through the opening of the slide groove 15. Since the slide groove 15 is an open structure formed by the main board protrusion 141 and the slide groove protrusion 142 and the main board 1, the operator can clearly see the insertion position and direction during assembly, which reduces the assembly difficulty and improves the assembly efficiency.

[0063] The main board protrusion 141 and the slide groove protrusion 142 provide clear guidance and positioning for the insertion of the movable plate 2. During the insertion process, the movable plate 2 will enter the slide groove 15 along the edge of the main board protrusion 141 and the slide groove protrusion 142, ensuring that the movable plate 2 is accurately installed in the predetermined position and ensuring the normal implementation of the subsequent sliding function.

[0064] The open-type slide 15 structure makes cleaning easier. Dust and debris can easily enter the slide 15. If the slide 15 were a closed structure, it would be more difficult to clean. However, with the slide 15 formed by the main board protrusion 141 and the slide protrusion 142, the operator can directly clean the inside. Using tools such as brushes or compressed air can effectively remove debris and keep the slide 15 clean, thereby ensuring the smooth sliding of the movable plate 2.

[0065] If the movable plate 2 or the slide rail 15 malfunctions, such as the movable plate 2 getting stuck or the slide rail protrusion 142 being damaged, due to the structural characteristics of the slide rail 15, maintenance personnel can easily disassemble and inspect the movable plate 2, and it is also easier to repair or replace components such as the slide rail protrusion 142, reducing maintenance time and costs.

[0066] Compared to some integral slide rail structures, this slide rail part 14, which consists of a motherboard protrusion 141 and a slide groove protrusion 142, reduces unnecessary material usage and effectively reduces the weight of the motherboard 1 and the entire device while ensuring structural strength and function.

[0067] like Figures 1 to 6 As shown, in this embodiment, there are multiple groove protrusions 142, which are spaced apart along the length direction of the main board protrusions 141.

[0068] Multiple sliding protrusions 142, spaced apart along the length of the main board protrusions 141, provide segmental support and guidance as the movable plate 2 is inserted into the sliding groove 15 and slides. When the movable plate 2 slides within the sliding groove 15, it will contact each sliding protrusion 142 in sequence. The sliding protrusions 142 restrict the displacement of the movable plate 2 in the direction perpendicular to the sliding direction, ensuring that the movable plate 2 slides smoothly along the predetermined path.

[0069] When the movable plate 2 is subjected to external forces (such as pushing or pulling forces) during the sliding process, the multiple sliding groove protrusions 142 can distribute these external forces to different locations. For example, when the movable plate 2 is subjected to lateral forces, each sliding groove protrusion 142 shares the lateral force, avoiding excessive local stress that could damage the sliding groove protrusions 142 or the movable plate 2, thus ensuring the stability and durability of the structure.

[0070] Compared to continuous one-piece slide rail protrusions, the use of multiple slide rail protrusions 142 at intervals reduces the amount of material used. In the manufacturing process, especially when using injection molding, extrusion and other processes to produce the main board 1 and slide rail 14, it can reduce the cost of raw materials and also reduce energy consumption in the production process, which meets the requirements of energy conservation and environmental protection.

[0071] Manufacturing multiple spaced groove protrusions 142 is easier than manufacturing continuous one-piece groove protrusions. In terms of mold design and processing, spaced groove protrusions 142 can simplify the mold structure and reduce the difficulty and cost of mold manufacturing. For example, in injection molds, spaced groove protrusions 142 can be demolded in a simpler way, which improves production efficiency.

[0072] When the movable plate 2 is inserted into the slide groove 15, the slide groove protrusions 142 arranged at intervals make it easier to insert the movable plate 2. Since there are gaps between the slide groove protrusions 142, the movable plate 2 can have a certain margin of error during the insertion process. The operator does not need to precisely align each position, which reduces the assembly difficulty and improves the assembly efficiency.

[0073] The gaps between the spaced slide protrusions 142 facilitate the cleaning of debris in the slide 15. Dust, debris and other debris can be more easily removed through these gaps, preventing debris from accumulating in the slide and affecting the sliding performance of the movable plate 2. At the same time, if a slide protrusion 142 is damaged, it is more convenient to replace a single slide protrusion 142 than to replace a continuous one-piece slide protrusion, thus reducing maintenance costs.

[0074] The multiple spaced groove protrusions 142 reduce the contact area between the movable plate 2 and the groove protrusions 142, thereby reducing the friction during the sliding process. The smaller friction makes the sliding of the movable plate 2 smoother, the operation easier, and improves the user experience. In addition, since the groove protrusions 142 support the movable plate 2 in segments, the jamming phenomenon caused by the deformation of the movable plate 2 is reduced, further ensuring the smoothness of the sliding.

[0075] When the movable plate 2 or the main plate 1 undergoes slight deformation due to factors such as temperature changes or external forces, the spaced sliding groove protrusions 142 can better adapt to this deformation. Compared with continuous one-piece sliding groove protrusions, multiple spaced sliding groove protrusions 142 have a certain degree of flexibility and can buffer the impact of deformation to a certain extent, ensuring that the movable plate 2 can still slide normally, thus improving the reliability and stability of the product.

[0076] like Figures 1 to 6 As shown, each of the motherboard protrusions 141 in this embodiment has a connecting block 143 on its side wall that is relatively far from the slide groove protrusion 142. The connecting block 143 is mainly used to realize the connection between the motherboard protrusion 141 and the base station. When it is necessary to assemble the motherboard 1 and the base station, the connecting block 143 can be connected to the base station through a specific connection method (such as bolt connection, snap connection, welding, etc.) to fix the motherboard 1 in the required position.

[0077] like Figures 1 to 6 As shown, a sealing component is also provided between the back of the main board 1 and the movable plate 2 in this embodiment. When the movable plate 2 slides on the main board 1 until the second vent 21 and the first vent 11 are completely misaligned, the sealing component and the plate body of the movable plate 2 are sealed.

[0078] Specifically, the movable plate 2 can slide on the main plate 1. The relative positions of the second vent 21 and the first vent 11 will change as the movable plate 2 slides. When the movable plate 2 slides to the point where the second vent 21 and the first vent 11 are completely misaligned, it means that the ventilation channel is blocked. At this time, the sealing component interacts with the plate body of the movable plate 2 to form a sealed state. This is because the sliding of the movable plate 2 causes it to contact the sealing component, triggering the deformation or fitting action of the sealing component, thereby achieving a seal.

[0079] The sealing components are usually made of materials with elasticity and sealing properties, such as rubber and silicone. When the movable plate 2 slides into place, the sealing component is squeezed by the body of the movable plate 2 and undergoes elastic deformation. This deformation allows the sealing component to fit tightly against the body of the movable plate 2, filling the gap between them and preventing the passage of substances such as gas, liquid or dust, thereby achieving a sealing effect.

[0080] like Figures 1 to 6 As shown, the sealing assembly of this embodiment includes a sealing ring 3 surrounding the outside of the first vent 11.

[0081] Specifically, the sealing ring 3 is arranged around the outside of the first vent 11. When the movable plate 2 slides on the main plate 1 until the second vent 21 and the first vent 11 are completely misaligned, the body of the movable plate 2 will come into contact with the sealing ring 3. Due to the pressure generated by the sliding of the movable plate 2, the sealing ring 3 will be squeezed.

[0082] The sealing ring is typically made of an elastic material (such as rubber or silicone), which deforms elastically when compressed. This deformation allows the sealing ring to tightly fill the gap between the movable plate 2 and the main plate 1, including any tiny gaps and uneven surfaces. This prevents substances such as gas, liquid, or dust from exchanging with the outside through the first vent 11, achieving a sealing effect.

[0083] The ring-shaped design can surround the first vent in all directions, forming a continuous sealed barrier. No matter which direction external substances try to enter the vent, they can be effectively blocked by the sealing ring, providing relatively comprehensive protection.

[0084] The structure of sealing rings is relatively simple, and they can usually be mass-produced through processes such as molding and injection molding, resulting in low manufacturing costs.

[0085] The installation process is also relatively simple; it only requires wrapping it around the outside of the first vent 11. This not only reduces the difficulty and time cost of installation, but also makes it easier to operate during subsequent maintenance and replacement.

[0086] like Figures 1 to 6 As shown, the back of the motherboard 1 in this embodiment is provided with an assembly groove 16, and the sealing ring 3 is provided with an assembly protrusion 31 corresponding to the assembly groove 16.

[0087] Specifically, the mounting groove 16 on the back of the motherboard 1 and the mounting protrusion 31 on the sealing ring 3 correspond to each other in shape and position. When installing the sealing ring 3, the mounting protrusion 31 can be precisely embedded into the mounting groove 16, just like two pieces of a jigsaw puzzle fitting together. Through this physical correspondence, the sealing ring 3 is quickly and accurately positioned on the motherboard 1, ensuring that the sealing ring 3 can be correctly positioned around the outside of the first vent 11.

[0088] When the mounting protrusion 31 is embedded in the mounting groove 16, due to the friction and tight fit between the mounting protrusion and the mounting groove, the sealing ring 3 can be firmly fixed on the main board 1. Even if the equipment is subjected to vibration, impact, or relative sliding between the movable plate 2 and the main board 1, the sealing ring 3 will not easily shift or fall off, thus ensuring the stability of the sealing effect.

[0089] The corresponding design of the mounting protrusion 31 and the mounting groove 16 eliminates the need for installers to spend a lot of time adjusting the position of the sealing ring when installing it. They can simply align the mounting protrusion with the mounting groove and insert it, which greatly shortens the installation time and improves production efficiency. This simple and intuitive installation method reduces the skill level required of installers and reduces the probability of problems caused by improper installation.

[0090] Accurate positioning ensures that the sealing ring can be precisely set around the first vent 11, avoiding the problem of poor sealing caused by the position deviation of the sealing ring. Only when the sealing ring is correctly positioned can the first vent 11 be effectively sealed when the movable plate 2 and the main plate 1 are in contact, preventing leakage of gas, liquid, etc.

[0091] The secure fixing ensures that the sealing ring remains in the correct position during use and will not shift due to external factors. This guarantees the long-term stability of the sealing performance, allowing the equipment to maintain a good sealing effect during long-term operation.

[0092] In mass production, the design of assembly protrusions and grooves ensures that the installation position and condition of the sealing rings on each product are consistent, thereby improving the consistency of product quality.

[0093] Because the sealing ring can be stably fixed on the motherboard, the risk of equipment failure caused by the sealing ring shifting or falling off is reduced, the reliability and stability of the entire product are improved, and after-sales maintenance costs are reduced.

[0094] When the sealing ring needs to be replaced due to wear or damage from long-term use, simply remove the mounting protrusion from the mounting groove to easily remove the old sealing ring and install the new one. This design makes the sealing ring replacement process simple and easy, reducing equipment downtime for maintenance.

[0095] Preferably, in this embodiment, a limiting component is provided between the main board 1 and the movable plate 2 to restrict their relative movement. The limiting component includes a first limiting block 22 at the top of the movable plate 2, a first limiting part 17 on the main board 1 corresponding to the first limiting block 22, a second limiting block 23 at or near the tail end of the movable plate 2, and a second limiting part 18 on the main board 1 corresponding to the second limiting block 23. When the movable plate 2 slides on the main board 1 to the point where the second vent 21 and the first vent 11 are connected, the first limiting block 22 cooperates with the first limiting part 17 to prevent the movable plate 2 from continuing to slide on the main board 1 in the same direction, so that the second vent 21 and the first vent 11 remain connected.

[0096] When the movable plate 2 slides on the main board 1 until the second vent 21 and the first vent 11 are completely misaligned, the second limiting block 23 cooperates with the second limiting part 18 to prevent the movable plate 2 from continuing to slide on the main board 1 in the same direction, so that the second vent 21 and the first vent 11 remain completely misaligned.

[0097] The limiting component restricts the sliding range of the movable plate 2, avoiding unnecessary friction and collision between the movable plate 2 and the main plate 1 due to excessive sliding, reducing wear on the movable plate 2 and the main plate 1, and extending the service life of key components of the equipment.

[0098] Stable vent alignment and staggered arrangement can reduce wear and damage to the vent edges, ensure the vent's sealing and integrity, and further improve the overall service life of the equipment.

[0099] During equipment maintenance and repair, the two working positions (connected and staggered) of the movable plate 2 determined by the limit component are very clear. Maintenance personnel can quickly and accurately determine whether the position of the movable plate 2 is normal, which facilitates the inspection and repair of the vent and related components.

[0100] Because the sliding range of the movable plate 2 is limited, it is more convenient to disassemble and install the movable plate 2. Maintenance personnel can operate according to the position indicated by the limit component, which improves maintenance efficiency and reduces maintenance costs.

[0101] Preferably, in this embodiment, the first limiting part 17 is the top of the motherboard 1, the second limiting part 18 is the bottom of the slide groove protrusion 142 near the bottom of the motherboard 1, and the first limiting part 17 is the handle on the movable plate 2. With this design, the structure of the motherboard 1 and the movable plate 2 can be utilized to reduce the number of parts and make the structure of the motherboard 1 and the movable plate 2 more compact.

[0102] Preferably, the second limiting block 23 is also provided with an assembly inclined surface 231, which facilitates the initial insertion and assembly between the movable plate 2 and the main plate 1.

[0103] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
