Description

Technical Field

[0001] This utility model belongs to the field of connecting accessories technology, specifically relating to a pneumatic connector with integrated air filtration function. Background Technology

[0002] In pneumatic systems, pneumatic connectors, as key components connecting pipelines and various pneumatic equipment, are traditionally used only to achieve physical connections between pipelines. However, the compressed air entering the pneumatic system usually contains a variety of contaminants, such as particulate impurities, moisture, and oil mist. These contaminants pose a threat to the normal operation of pneumatic equipment and may lead to problems such as accelerated wear, performance degradation, or even failure.

[0003] Although standalone air filtration solutions exist on the market, installing the filter separately from the pneumatic connector increases the complexity and overall cost of the system, while also taking up more installation space. Utility Model Content

[0004] This utility model addresses the aforementioned problems in the existing technology by proposing a pneumatic connector with integrated air filtration function.

[0005] This utility model can be achieved through the following technical solutions:

[0006] A pneumatic connector with integrated air filtration function, comprising:

[0007] The outer shell has its internal cavity divided into an upper cavity and a lower cavity by a partition;

[0008] The filter element is detachably disposed within the lower cavity;

[0009] A base assembly, which is movably connected to the axial direction of the housing, is used to fix the external air tube;

[0010] An elastic reset element is disposed between the base assembly and the housing, and is used to drive the base assembly to reset axially;

[0011] When the elastic reset mechanism is not subjected to external force, the base assembly is located inside the lower cavity and presses the filter element against the partition.

[0012] When the base assembly is pressed by an external force, the base assembly extends out of the lower cavity to connect or disconnect the air pipe, and retracts through the elastic reset mechanism after the external force is removed, thus re-pressing the filter element.

[0013] As a further improvement of this utility model, the base assembly includes a venting base, a connecting rod, and a top cap. The connecting rod passes through the partition, and the venting base and the top cap are respectively fixed to both ends of the connecting rod. The top cap is located in the upper cavity, and the venting base is located in the lower cavity.

[0014] As a further improvement of this utility model, the ventilated base is provided with several air inlets for compressed air to pass through, and the partition is provided with several air outlets, which are connected to the air inlets.

[0015] As a further improvement of this utility model, the filter element is sleeved on the connecting rod and placed on the ventilation base. When the ventilation base presses the filter element on the partition, the upper and lower end faces of the filter element cover the air inlet and the air outlet respectively.

[0016] As a further improvement of this utility model, the elastic reset member is configured as a reset spring, with both ends of the reset spring abutting against the top cap and the partition respectively, and the reset spring continuously providing elastic force to the vent base toward the partition.

[0017] As a further improvement of this utility model, the ventilation base can be configured as a planar structure or an umbrella structure. When the ventilation base is configured as an umbrella structure, it protrudes outward toward the end away from the filter element.

[0018] As a further improvement of this utility model, the outer circumferential surface of the ventilation base has a protruding latch. When the air tube is fitted onto the ventilation base, the latch pushes the air tube wall outward until it abuts against the inner wall of the outer shell.

[0019] As a further improvement of this utility model, when not subjected to external force, the outer circumferential surface of the vent base is located in the lower cavity. After pressing the top cap, the vent base moves outward until its outer circumferential surface moves out of the lower cavity.

[0020] As a further improvement of this utility model, the filter element is configured as a multi-layer filter structure, which is configured as a coarse filter screen, a filter membrane, and an activated carbon adsorption layer from the air inlet side to the air outlet side.

[0021] As a further improvement of this utility model, the outer wall of the upper cavity of the outer shell has connecting threads.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Integrated design: The air filtration function is directly integrated into the pneumatic connector, avoiding the complexity of needing to install a filter separately in traditional systems and simplifying the overall structure of the system;

[0024] 2. Saves space and cost: Since no additional space is needed to install a separate filtration device, it not only reduces installation costs but also saves valuable installation space, making it especially suitable for space-constrained application environments;

[0025] 3. Improved maintenance efficiency: The removable design of the filter element allows users to perform maintenance and replacement conveniently and quickly without complicated tools or steps, thereby improving maintenance efficiency and reducing downtime.

[0026] 4. Enhanced ease of use: The axial movement design of the base assembly makes the connection and disassembly of the air tube extremely simple, greatly improving the user's operating experience;

[0027] 5. Ensure high-efficiency filtration: The elastic reset mechanism ensures that the filter element is always in the best compressed state, preventing leakage caused by loosening. The upper and lower end faces of the filter element cover the air inlet and outlet, thus ensuring continuous high-efficiency filtration performance. Attached Figure Description

Detailed Implementation

[0036] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.

[0037] like Figures 1-7 As shown, this utility model provides a pneumatic connector with integrated air filtration function, comprising:

[0038] The outer shell 100 has its inner cavity divided into an upper cavity 101 and a lower cavity 102 by a partition 110, wherein the lower cavity 102 serves as a filter cavity for gas flow.

[0039] The filter element 120 is detachably installed in the lower cavity 102, which facilitates regular maintenance and replacement and ensures long-term stable filtration performance.

[0040] The base assembly 130 is movably connected to the axial direction of the housing 100. The base assembly 130 is used to fix the external air tube 200 and can move axially to facilitate the connection or disconnection of the air tube 200.

[0041] The elastic reset member 140 is disposed between the base assembly 130 and the housing 100 and is used to drive the base assembly 130 to reset axially.

[0042] When the elastic reset mechanism is not subjected to external force, the base assembly 130 is located inside the lower cavity 102 and presses the filter element 120 onto the partition 110 to ensure sealing and efficient filtration.

[0043] When it is necessary to connect or disconnect the air tube 200, simply apply pressure to the base assembly 130 to make it extend out of the lower cavity 102. After completing the corresponding operation, remove the external force, and the base assembly 130 will automatically retract to its original position through the elastic reset mechanism, re-press the filter element 120, and restore the working state.

[0044] Because the pneumatic connector has an integrated filter element 120, it can filter the compressed air during the ventilation process. The installation and removal of the air pipe 200 can be achieved simply by moving the base assembly 130 axially, making the operation simple and convenient.

[0045] Overall, the pneumatic connector provided in this embodiment has at least the following advantages:

[0046] 1. Integrated design: The air filtration function is directly integrated into the pneumatic connector, avoiding the complexity of needing to install a filter separately in traditional systems and simplifying the overall structure of the system;

[0047] 2. Saves space and cost: Since no additional space is needed to install a separate filtration device, it not only reduces installation costs but also saves valuable installation space, making it especially suitable for space-constrained application environments;

[0048] 3. Improved maintenance efficiency: The removable design of the filter element 120 allows users to perform maintenance and replacement conveniently and quickly without complicated tools or procedures, thereby improving maintenance efficiency and reducing downtime.

[0049] 4. Enhanced ease of use: The axial movement design of the base assembly 130 makes the connection and disassembly of the air tube 200 extremely simple, greatly improving the user's operating experience;

[0050] 5. Ensure high-efficiency filtration: The elastic reset mechanism ensures that the filter element 120 is always in the optimal compressed state, preventing leakage caused by loosening, thereby ensuring continuous high-efficiency filtration performance.

[0051] Preferably, the base assembly 130 includes a ventilated base 131, a connecting rod 132, and a top cap 133. The connecting rod 132 passes through the partition 110. The ventilated base 131 and the top cap 133 are respectively fixed to both ends of the connecting rod 132. The top cap 133 is located in the upper cavity 101, and the ventilated base 131 is located in the lower cavity 102. Specifically:

[0052] Ventilation base 131: Several air inlets 1311 are provided on its surface for compressed air to pass through;

[0053] Partition 110: Several air outlets 111 are provided at positions corresponding to the ventilation base 131 to ensure that gas can flow smoothly from the air inlet 1311, be purified by the filter element 120, and then flow out from the air outlet 111.

[0054] Filter element 120 arrangement: The filter element 120 is sleeved on the connecting rod 132 and placed on the ventilation base 131. When the ventilation base 131 presses the filter element 120 against the partition 110, the upper and lower end faces of the filter element 120 tightly cover the air inlet 1311 and the air outlet 111 respectively, ensuring the sealing and high efficiency of the filtration process.

[0055] By designing the filter element 120 to closely cover the air inlet 1311 and the air outlet 111, it is ensured that the gas must be effectively filtered by the filter element 120, thereby significantly improving the filtration efficiency and effect.

[0056] In addition, since the filter element 120 is sleeved on the connecting rod 132, when it is necessary to replace or clean the filter element 120, simply remove the top cap 133 and then take the vent base 131 out of the lower cavity 102 to complete the operation. No complicated tools or steps are required, which greatly facilitates the user's daily maintenance work.

[0057] Preferably, the elastic reset member 140 is configured as a reset spring, with both ends of the reset spring abutting against the top cap 133 and the partition 110 respectively, so that the reset spring can continuously provide the vent base 131 with elastic force in the direction of the partition 110.

[0058] The design of the reset spring provides a constant clamping force, ensuring that the filter element 120 is always tightly pressed against the partition 110 during normal use, preventing leakage or reduced filtration efficiency due to loosening, thereby ensuring sealing and high efficiency during the filtration process.

[0059] Preferably, the ventilation base 131 can be configured as a planar structure or an umbrella structure. When the ventilation base 131 is configured as an umbrella structure, its end facing away from the filter element 120 protrudes outward. It should be noted that both of these structures of the ventilation base 131 can play the role of ventilation, but the umbrella structure, due to its outward protrusion design, expands the flow area of ​​its air inlet 1311, thereby increasing the air flow rate.

[0060] The connection method between the ventilation base 131 and the external air pipe 200 is explained as follows:

[0061] Preferably, the outer circumferential surface of the ventilation base 131 has a protruding latch 13121311. When the air tube 200 is fitted onto the ventilation base 131, the latch 13121311 pushes the air tube 200 outward until it abuts against the inner wall of the outer shell 100, thereby ensuring the stability and firmness of the air tube 200 after installation.

[0062] Specifically: When it is necessary to disassemble or assemble the air tube 200, simply press the top cap 133 to move the ventilation base 131 axially to its outer circumferential surface (i.e. the mounting surface of the air tube 200) and move it out of the lower cavity 102, so that the connection or disassembly of the air tube 200 can be easily performed.

[0063] Subsequently, after the air tube 200 is installed, simply loosen the top cap 133, and the ventilation base 131 will automatically retract into the lower cavity 102 under the action of the return spring. At this time, the latch 13121311 pushes the wall of the air tube 200 outward until it contacts the inner wall of the outer shell 100 and forms a stable latch connection, ensuring that the air tube 200 will not easily loosen or fall off.

[0064] The design utilizes the top cap 133 and the elastic reset member 140 to allow users to easily move the ventilation base 131 axially by simply pressing the top cap 133, thereby enabling quick connection or disconnection of the air tube 200, which greatly facilitates user operation.

[0065] Preferably, the filter element 120 is configured with a multi-layer filtration structure, which consists of a coarse filter screen, a filter membrane, and an activated carbon adsorption layer, arranged sequentially from the air inlet side to the air outlet side.

[0066] Coarse filter: Used for initial interception of larger particles and impurities;

[0067] Filter membrane: Further removes finer particles and suspended solids;

[0068] Activated carbon adsorption layer: mainly used to adsorb pollutants such as moisture, oil mist and odors in the air.

[0069] By employing a combination of coarse filter, filter membrane, and activated carbon adsorption layer, it is possible to achieve graded treatment of pollutants of different sizes and types in the air:

[0070] First, a coarse filter removes large particles of impurities, reducing the burden on subsequent filter layers. Then, a filter membrane further removes fine particles. Finally, an activated carbon adsorption layer effectively removes moisture, oil mist, and other volatile organic compounds (VOCs), thereby improving the overall filtration efficiency.

[0071] Because each layer is optimized for specific types of contaminants, this not only improves the efficiency of a single layer but also reduces the stress on other layers, helping to extend the lifespan of the entire filter element 120. For example, the coarse filter can protect the filter membrane from direct impacts from large particles, reducing its wear rate.

[0072] In addition, the materials of the coarse filter screen and the filter membrane include, but are not limited to, PE, stainless steel, and copper, and the structures of the coarse filter screen and the filter membrane include, but are not limited to, sintered pore structures, foamed structures, and mesh structures.

[0073] Preferably, the outer wall of the upper cavity 101 of the housing 100 has connecting threads, which are used to connect to pneumatic components.

The above are specific embodiments of this utility model.
