[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] The terms "first", "second", etc. in the specification and claims of the present utility model and the above-mentioned accompanying drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0027] Referring to "embodiment" or "embodiment mode" herein means that a specific feature, structure or characteristic described in connection with the embodiment or embodiment mode can be included in at least one embodiment of the present utility model. The appearance of this phrase at various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0028] In the related art, there is usually a certain amount of residual fluid in the filter element base (1). If these residual fluids are not properly treated, they are likely to leak when the filter element (7) is replaced, and may further cause pollution to the external environment, the newly installed filter element (7), and other positions of the filter element base (1). However, the common filter element bases (1) at present cannot effectively treat these residual fluids, resulting in the existence of this part of the fluid in the filter element base (1), which has a certain impact on the usability of the fluid treatment equipment.

[0029] In order to improve or solve the above technical problems, the inventors of the present application have conducted long-term research and proposed at least the following embodiments.

[0030] Refer to Figures 1 to 4 , Figure 1 which is a schematic cross-sectional structure diagram of the fluid treatment equipment provided by the embodiment of the present utility model. Figure 2 which is a schematic assembly structure diagram of the filter element base provided by the embodiment of the present utility model. Figure 3 is Figure 2 the schematic cross-sectional structure diagram of the A-A' section in Figure 4 which is a schematic cross-sectional structure diagram of the filter element base provided by the embodiment of the present utility model. Among them,Figure 3 The first position is shown as X, Figure 4 and the second position is shown as Y.

[0031] The present application provides a filter element base (1) for docking with a filter element (7). The filter element base (1) may include a base body (2) and a separator (3). A first flow channel (21) and a groove are formed in the base body (2). The separator (3) is provided with a liquid through hole (34), and a second flow channel (4) is formed in at least one of the base body (2) and the separator (3). One end of the second flow channel (4) communicates with the outside, and the other end communicates with the groove of the base body (2).

[0032] In this embodiment, by providing the second flow channel (4) that communicates the outside and the groove on the separator (3) and / or the base body (2), and the second flow channel (4) is isolated from the first flow channel (21), the fluid leaked into the groove of the base body (2) is discharged by using the second flow channel (4), reducing the probability of this part of the fluid contaminating the first flow channel (21). When the first flow channel (21) is not docked with the filter element (7), since the present application can discharge the residual fluid in the groove to the outside through the second flow channel (4), it can avoid this part of the fluid from leaking and contaminating other parts of the filter element base (1), or contacting the subsequent filter element (7) to cause contamination.

[0033] Optionally, the separator (3) may include a first blocking portion (31) disposed on the surface of the separator (3) facing the base body (2). When the separator (3) is in the first position relative to the base body (2), the first blocking portion (31) can abut against the groove on the periphery of the second flow channel (4), thereby isolating the second flow channel (4) from the groove. When the separator (3) is in the second position relative to the base body (2), the first blocking portion (31) leaves the groove on the periphery of the second flow channel (4), enabling the second flow channel (4) to communicate with the groove.

[0034] Moreover, regardless of whether it is in the first position or the second position, the second flow channel (4) is isolated from the liquid through hole (34) and the first flow channel (21), preventing the outside from directly communicating with the liquid through hole (34) and the first flow channel (21), and avoiding contamination of the liquid through hole (34) and the first flow channel (21) by the outside.

[0035] If the groove communicates with the outside at any time, the fluid leaked into the groove cannot be effectively controlled, and it may cause contamination due to the outflow of this part of the fluid at an unexpected time point. With the structure provided in this embodiment, the second flow channel (4) does not communicate the groove and the outside at any time, so that the timing of discharging the fluid leaked into the groove is controllable, improving the usability of the filter element base (1).

[0036] Optionally, the second flow channel (4) may specifically include a first groove (41) that communicates with the tank body. The first groove (41) and the first blocking portion (31) may be disposed on the same side surface of the separator (3), and can cooperate with the base body (2) to form at least part of the second flow channel (4). The first groove (41) may also be disposed on the surface of the base body (2) facing the separator (3), and cooperate with the separator (3) to form at least part of the second flow channel (4). When the separator (3) is in the second position relative to the base body (2), another part of the second flow channel (4) is docked with the first groove (41), thereby forming a complete second flow channel (4).

[0037] Specifically, the first groove (41) may be disposed on the surface of at least one of the separator (3) and the base body (2). For example, part of the first groove (41) is disposed on the separator (3), and another part of the first groove (41) is correspondingly disposed on the surface of the base body (2). When the separator (3) is in the second position relative to the base body (2), the base body (2) and the separator (3) on the periphery of the first groove (41) abut against each other, so as to communicate the first grooves (41) on the base body (2) and the separator (3) to form at least part of the second flow channel (4), enabling the fluid in the tank body to flow out to the outside through the second flow channel (4) without leaking to positions outside the second flow channel (4).

[0038] Refer to Figure 5 , Figure 5 in which the first position is shown as X. Figure 5 This is another cross-sectional structural schematic diagram of the filter element base provided by the embodiment of the present invention. The first blocking portion (31) may specifically be disposed on the separator (3) and be opposite to the first groove (41). The first blocking portion (31) and the first groove (41) can cooperate with the surface of the base body (2) facing the separator (3), so that when the separator (3) is in the first position, the second flow channel (4) is isolated from the tank body by using the first blocking portion (31). Its structure is relatively simple and reliable, and can reduce the molding cost of the second flow channel (4).

[0039] Furthermore, the filter element base (1) may further include an elastic member (5). The elastic member (5) is disposed between the base body (2) and the separator (3). Under the elastic action, both sides of the elastic member (5) can respectively abut against the separator (3) and the base body (2) on the periphery of the first groove (41), thereby sealing the gap between the base body (2) and the separator (3) and isolating the first groove (41) from the first flow channel (21). The elastic member (5) disposed here can improve the sealing performance of the first groove (41), making it difficult for the fluid in the tank body to leak during the process of entering the second flow channel (4), and reducing the probability of polluting other structures.

[0040] Optionally, the separator (3) is rotatably mounted on the base body (2). A first fluid opening (22) may be formed on one surface of the base body (2) that forms the groove body. The first fluid opening (22) can communicate with the first flow channel (21). A second blocking portion (33) may be provided on one surface of the separator (3) facing the base body (2). When the separator (3) is in the first position relative to the base body (2), the second blocking portion (33) can block the first fluid opening (22) to isolate the first flow channel (21) and the second flow channel (4).

[0041] Wherein, with the axis of rotation of the separator (3) as the center of the circle, the first fluid opening (22), the liquid through hole (34), and the second blocking portion (33) can be arranged on the same arc. In this embodiment, the way the separator (3) moves between the first position and the second position relative to the base body (2) is rotation. The first fluid opening (22), the liquid through hole (34), and the second blocking portion (33) are arranged on the same arc relative to the axis of rotation, so that during the process of the separator (3) moving from the first position to the second position, the structure corresponding to the first fluid opening (22) can gradually be converted from the liquid through hole (34) to the second blocking portion (33).

[0042] Optionally, when the separator (3) is in the first position relative to the base body (2), the elastic member (5) can abut between the second blocking portion (33) and the base body (2) on the periphery of the first fluid opening (22) to improve the sealing effect.

[0043] Further, when the separator (3) is in the second position relative to the base body (2), the elastic member (5) can abut between the separator (3) on the periphery of the liquid through hole (34) and the base body (2) on the periphery of the first fluid opening (22). The elastic member (5) connects the liquid through hole (34) and the first flow channel (21), and can isolate the groove body from the first flow channel (21), thereby improving the stability of the docking between the liquid through hole (34) and the first fluid opening (22).

[0044] Specifically, the elastic member (5) in the filter element base (1) can be relatively fixed to the base body (2) and abut against the separator (3).

[0045] Optionally, as Figure 3 、 4 shown, the groove body can specifically be a circular groove (23), and the first fluid opening (22) is formed on the bottom surface of the circular groove (23). The radial dimension of the separator (3) is slightly smaller than the inner diameter of the circular groove (23), so that the separator (3) can be embedded in the circular groove (23).

[0046] Among them, the axis of rotation of the spacer (3) relative to the base body (2) can be the center of the circular groove (23). By using the circular groove (23) provided in this embodiment, the spacer (3) and the movement trajectory of the spacer (3) can be limited, thereby improving the docking stability between the first flow channel (21), the liquid through hole (34), and the second blocking portion (33).

[0047] Further, referring to Figure 5 , the filter element base (1) may further include a negative pressure chamber (6), and the end of the second flow channel (4) away from the tank body may specifically communicate with the negative pressure chamber (6). The negative pressure chamber (6) can suck the fluid in the tank body through the second flow channel (4) by using negative pressure. The method provided in this embodiment can suck at the end of the second flow channel (4) connected to the outside, so as to promote the liquid in the tank body to be discharged to the outside through the second flow channel (4) and the negative pressure chamber (6).

[0048] Optionally, the filter element base (1) may further include a power member. The power member can be arranged in the second flow channel (4) and be in contact with the fluid in the tank body. When the power member works, it can promote the fluid in the tank body to move towards the direction close to the end of the second flow channel (4) away from the tank body, so that the fluid in the tank body can be discharged to the outside through the second flow channel (4).

[0049] Referring to Figure 6 , Figure 6 is a schematic structural diagram of the spacer provided in the embodiment of the present invention. The spacer (3) can specifically be a plate-like structure, and the spacer (3) may further be provided with reinforcing ribs (35). The number of the reinforcing ribs (35) is multiple, and the multiple reinforcing ribs (35) intersect with each other and are parallel to the plate surface. Due to the setting of the first groove (41), the structural strength of the plate-like spacer (3) may be affected. Therefore, reinforcing ribs (35) can be added to the spacer (3), so as to increase the strength of the spacer (3) through multiple intersecting ones, make its structure more stable, and thus improve the service life of the filter element base (1).

[0050] Further, the reinforcing ribs (35) can intersect with the first blocking portion (31), the second blocking portion (33), and the liquid through hole (34), so as to maintain the strength of the structure and reduce the probability of deformation.

[0051] Specifically, when the second flow channel (4) includes the first groove (41) opened on the spacer (3), the setting direction of the reinforcing ribs (35) can be perpendicular to or intersect with the first groove (41), so as to improve the strength of the spacer (3) in different directions.

[0052] Referring to Figure 5 , 6, when the isolation member (3) moves between the first position and the second position relative to the base body (2) in a rotational manner, the isolation member (3) may further include a rotating shaft (36). The reinforcing rib (35) may also be arranged around the isolation member (3) with the rotating shaft (36) as the center to form a circular reinforcing rib (35), thereby strengthening the strength of the isolation member (3) in the rotational direction of the isolation member (3). A plurality of reinforcing ribs (35) perpendicular to the circular reinforcing rib (35) may further extend from the rotating shaft (36), and a plurality of reinforcing ribs (35) tangent to the circular reinforcing rib (35) may also be provided near the circular reinforcing rib (35) to enhance the strength from multiple different directions.

[0053] Specifically, the rotating shaft (36) may be coaxial with the center of the circular groove (23).

[0054] Refer to Figure 1 , this application also provides an embodiment of a fluid processing device. The fluid processing device in this embodiment may include a filter element (7) and a filter element base (1) as described in any of the above embodiments. The filter element (7) is detachably fixed to the filter element base (1). Wherein, the fluid can flow into and out of the filter element (7) through the filter element base (1), so that the fluid processing device can input the fluid into the filter element (7) through the filter element base (1), use the filter element (7) to process the input fluid, and output the processed fluid through the filter element base (1). By using the fluid processing device provided in this embodiment, the fluid accumulated in the filter element base (1) can be discharged, the probability of pollution caused by these fluids can be reduced, and the usability of the fluid processing device can be improved.
