It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0033] The following is in conjunction with the appendix Figures 1 to 4 The present application provides a detailed description of a filter support structure through specific embodiments and application scenarios.

[0034] Some embodiments of this application provide a filter support structure, including a fixing plate 100, a fixing component 200, and a bracket 300.

[0035] like Figure 1 and Figure 3 As shown, the fixing plate 100 is connected to the bracket 300, and the fixing plate 100 is used to place the filter. By being securely connected to the bracket 300, the fixing plate 100 provides a reliable and durable rigid support platform for the filter, completely avoiding the problems of unstable support and uneven physical force caused by arm fatigue during handheld operation, and significantly improving the stability and sustainability of operation.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, the fixing component 200 is disposed on the fixing plate 100 and is used to fix the filter placed on the fixing plate 100. By setting the fixing component 200, the position of the filter on the fixing plate 100 is constrained, effectively preventing the filter from moving, shifting or accidentally falling off, ensuring the stability of the filter during filtration and dispensing, eliminating the interference and physical burden caused to the operator due to the need to support the filter, and improving the convenience of operation.

[0037] like Figure 1 and Figure 4As shown, along the projection of the fixed plate 100 along its width, there is an angle between the fixed plate 100 and the support 300. This angle causes the fixed plate 100 to be tilted relative to the support 300, utilizing gravity to allow the gas inside the filter (such as air or replacement gas) to naturally gather towards the higher area and be smoothly discharged, while simultaneously promoting the liquid's flow towards the lower outlet due to gravity. Furthermore, the tilted fixed plate 100, combined with the support height of the support 300, effectively lifts the filter and its connecting pipes off the workbench surface, significantly reducing the contact distance and surface area with potential contaminants, greatly minimizing the risk of contamination introduced during cleanroom operations due to proximity to the workbench. Simultaneously, it solves the problems of poor exhaust, liquid residue, and potential contamination associated with traditional horizontal placement, while avoiding the instability of handheld operation, significantly improving the efficiency, reliability, and operational safety of the filter transfer and dispensing process.

[0038] like Figure 1 and Figure 2 As shown, the fixing plate 100 has a stop portion 110 for abutting the filter. The stop portion 110 provided on the fixing plate 100 provides a physical barrier for the filter, limiting the possible downward displacement of the filter on the fixing plate 100, ensuring that the filter always stays in the predetermined position during operation, enhancing the overall restraint effect of the fixing assembly 200 on the filter, preventing the risk of interface loosening, leakage or detachment caused by accidental sliding of the filter, and ensuring the stability of the spatial relationship between the filter outlet and the flow guiding and dispensing device, making the liquid outflow and subsequent dispensing operations more controllable and smoother. Thus, while improving the convenience and efficiency of operation, it further reduces the risk of splashing, contamination or operation failure caused by filter position displacement, and strengthens the overall stability and reliability of the filtration and dispensing process in a high-cleanliness environment.

[0039] like Figure 1 As shown, the stop portion 110 is formed by bending the fixing plate 100. The stop portion 110 is directly formed by bending the fixing plate 100 body, making the stop portion 110 and the fixing plate 100 a single integral structure, reducing the number of parts and lowering production and maintenance costs. At the same time, the bent stop portion 110 naturally forms a smooth transition with the plane of the fixing plate 100, without sharp edges or protrusions, which improves operational safety and makes cleaning and sterilization of the entire support structure more convenient and efficient. Ultimately, while ensuring the reliability of the stop function, the overall integrity, cleanliness compatibility, and ease of use of the equipment are optimized.

[0040] In some embodiments, such as Figure 1 and Figure 2As shown, the fixing component 200 includes a fixing rope, the two ends of which are fixed to the fixing plate 100, forming a space for fixing the filter. By setting a fixing rope, it is easy to wrap around the filter body and apply a uniform and moderate binding force, effectively preventing the filter from moving relative to the fixing plate 100, and further ensuring the stability of the filter placed on the fixing plate 100.

[0041] In some embodiments, the fixing assembly 200 includes two fixing ropes, one end of which is fixed to the fixing plate 100, and the other ends are connected to each other to form a space for fixing the filter. The two fixing ropes start from different anchor points on the fixing plate 100 and converge near the filter, effectively preventing the filter from moving relative to the fixing plate 100, and further ensuring the stability of the filter placed on the fixing plate 100.

[0042] The two fixed ropes can be connected by Velcro, snaps, knots or other methods.

[0043] like Figure 2 As shown, the fixing plate 100 is provided with connecting holes 120 for the fixing rope to pass through. The pre-set connecting holes 120 on the fixing plate 100 provide a precise, stable and convenient anchoring channel for the fixing rope. Operators can quickly and accurately pass the end of the fixing rope through the hole and reliably fix it without the need for additional tools or complicated operations, which significantly simplifies the rope installation and disassembly process.

[0044] like Figure 1 As shown, the included angle is 30°-60°. Precisely limiting the included angle between the fixed plate 100 and the support 300 to the range of 30° to 60° ensures that the downward force on the filter on the fixed plate 100 is within a controllable range. Combined with the stop part 110 and the fixing component 200, this reliably constrains its position. Simultaneously, it provides operators with a clear and easily accessible operating posture for observing liquid levels, connecting pipelines, and guiding and dispensing. Ultimately, while ensuring efficient, thorough, and pollution-free filtration and dispensing, it maximizes the safety and ease of operation of the equipment.

[0045] like Figure 1As shown, the bracket 300 includes a base 320 and a support rod 310. One end of the support rod 310 is connected to the fixed plate 100, and the other end is connected to the base 320. The bracket 300 provides a stable bottom support platform through the base 320, effectively distributing the overall load of the equipment and filter, ensuring that it does not tip over or slide during operation. The support rod 310, as a rigid height and angle transmission component, precisely lifts and maintains the fixed plate 100 at a specific safe height and preset tilt angle from the workbench surface, providing a solid and reliable stability foundation for the entire filtration and dispensing process, completely eliminating the risk of shaking from handheld or simple support. At the same time, the wide contact area between the base 320 and the workbench surface further reduces the pressure per unit area, enhancing adaptability to different workbench conditions.

[0046] like Figure 4 As shown, the fixed plate 100 is rotatably connected to the bracket 300 via a damping pivot 330. By employing the damping pivot 330, operators can easily apply external force to adjust to the optimal tilt angle according to specific filter models, liquid characteristics, or operating habits. After removing the external force, the damping torque allows the fixed plate 100 to immediately and stably hover at any target angle, completely avoiding the free swaying, accidental sagging, or the cumbersome need for additional locking devices caused by the lack of damping in traditional hinges. This hovering improves the flexibility and efficiency of operation, while ensuring the absolute stability and reliability of the filter's posture during adjustment and subsequent filtration and dispensing processes, completely eliminating fluid control failures caused by unexpected angle changes.

[0047] It should be noted that the damping shaft 330 uses friction to suspend the fixed plate 100, and the damping shaft 330 is existing technology and a component that can be directly purchased on the market. Its structure will not be described in detail here.

[0048] In some embodiments, such as Figure 4 As shown, the bracket 300 is provided with a blocking surface 311 for limiting the rotation of the fixed plate 100. By providing the blocking surface 311, when the fixed plate 100 rotates to its maximum angle, the blocking surface 311 contacts the fixed plate 100, thereby limiting the continued rotation of the fixed plate 100.

[0049] In some embodiments, the fixing plate 100 is provided with a blocking block for abutting against the bracket 300. By providing the blocking block, when the fixing plate 100 rotates to its maximum angle, the blocking block contacts the bracket 300, thereby limiting the continued rotation of the fixing plate 100.

[0050] In some embodiments, the bracket 300 is provided with a blocking surface 311 for limiting the rotation of the fixing plate 100, and the fixing plate 100 is provided with a blocking block for abutting against the bracket 300. By providing the blocking surface 311 and the blocking block, when the fixing plate 100 rotates to its maximum angle, the blocking block contacts the blocking surface 311, thereby limiting the continued rotation of the fixing plate 100.

[0051] The fixing plate 100 has an arc-shaped surface that fits into the filter. The surface of the fixing plate 100 is designed to match the outer contour of the filter, which increases the contact area with the filter housing and achieves a conformal fit of the curved surface. This provides the filter with all-round and more uniform support, effectively dispersing the filter's own weight and the local load generated during operation, and increasing the stability of fixing the filter.

[0052] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0053] Furthermore, it should be noted that the scope of the methods and apparatus in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. In addition, features described with reference to certain examples may be combined in other examples.
