Description

Technical Field

[0001] The utility model relates to the field of water purifiers, in particular to a filter element seat and a fluid treatment device. Background Art

[0002] In a fluid treatment device such as a water purifier, a filter element device is generally provided to filter the input fluid through the filter element device, so as to output a fluid meeting the user's requirements. The filter element device will accumulate impurities during the continuous filtering process. When the impurity content is too high, the filter element device cannot perform the filtering function. Therefore, the filter element device is generally divided into two parts: a filter element and a filter element seat, so that the filter element can be conveniently disassembled, replaced or cleaned.

[0003] Since the filter element seat needs to introduce and discharge fluid to and from the filter element, there is usually a certain amount of residual fluid at the docking position between the filter element seat and the filter element. This part of the fluid may leak out when the filter element is disassembled. Therefore, a commonly used filter element seat is generally equipped with a separator that can move relative to the filter element seat. When the filter element is disassembled, the separator can be moved to a specified position to prevent the residual fluid from leaking out. However, due to the movable nature of the separator, when the filter element is normally docked with the filter element seat, it may also move under the action of the fluid, blocking the flow of the fluid between the filter element and the filter element seat; when the filter element is disassembled, the separator may also move under the action of the residual fluid, causing the residual fluid to leak out. Therefore, in actual use, the separator may interfere with the normal operation of the fluid device. Summary of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

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.

[0032] References herein to "embodiments" or "implementations" mean that the particular features, structures, or characteristics described in connection with the embodiments or implementations can be included in at least one embodiment of the present utility model. The phrase appearing in 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.

[0033] The filter element of a fluid processing device needs to be replaced after a period of use. When disassembling the filter element and the filter element seat, a certain amount of residual fluid remaining at the docking portion between the filter element seat and the filter element may leak out. Therefore, generally, a separator that can move relative to the filter element seat is provided in the common filter element seats currently. When disassembling the filter element, the separator can be moved to a specified position to prevent the residual fluid from leaking out. However, due to the movable nature of the separator, when the filter element is normally docked with the filter element seat, it may also move under the action of the fluid, blocking the flow of the fluid between the filter element and the filter element seat; when disassembling the filter element, the separator may also move under the action of the residual fluid, causing the residual fluid to leak out. Therefore, in actual use, the separator may interfere with the normal operation of the fluid device.

[0034] 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.

[0035] Refer to Figures 1-7 , Figure 1 which is a schematic cross-sectional structure diagram of a fluid processing device provided by an embodiment of the present utility model.

[0037] The present application provides a filter element seat (1), which includes a seat body (11), a separator (12), a seal (13), and a second limiting structure (2). Among them, a first flow channel (111) is formed in the seat body (11), and a second flow channel (121) is formed in the separator (12). The seal (13) includes a first limiting structure (131). The seal (13) can be disposed between the seat body (11) and the separator (12), and the seal (13) is relatively fixed to one of the seat body (11) and the separator (12). The second limiting structure (2) can be disposed on the other of the seat body (11) and the separator (12) relative to the seal (13).

[0038] Among them, when the separator (12) is in the first position relative to the seat body (11), the first limiting structure (131) can cooperate with the second limiting structure (2) so that the first flow channel (111) can be docked with the second flow channel (121). Or, when the separator (12) is in the first position relative to the seat body (11), the seal (13) can isolate the first flow channel (111) from the second flow channel (121).

[0039] The filter element seat (1) provided in this embodiment is provided with a first limiting structure (131) on the seal (13), one of the separator (12) and the seat body (11) is relatively fixed to the seal (13), and a second limiting structure (2) corresponding to the first limiting structure (131) is provided on the other that is not relatively fixed to the seal (13). Therefore, the cooperation relationship between the first limiting structure (131) and the second limiting structure (2) can be utilized. When the first flow channel (111) is docked with or isolated from the second flow channel (121), the separator (12) is relatively fixed to the seat body (11) through the seal (13), reducing the probability that the separator (12) undergoes relative displacement with the seat body (11) due to factors such as water flow, thereby improving the stability of the docking or isolation between the first flow channel (111) and the second flow channel (121).

[0040] Specifically, the first flow channel (111) can include a first opening (112), the second flow channel (121) can include a second opening (122), and the seal (13) can include a sealing portion (132). The seat body (11) and the separator (12) respectively abut against both sides of the sealing portion (132). The second limiting structure (2) is disposed on the periphery of the first opening (112) and / or the periphery of the second opening (122), and the first limiting structure (131) is disposed on the sealing portion (132).

[0041] In this embodiment, when the separator (12) is in the first position, the first opening (112) and the second opening (122) can communicate through the sealing portion (132), so that the first flow channel (111) is docked with the second flow channel (121). Thus, the docking portion of the first flow channel (111) and the second flow channel (121) is sealed by the sealing portion (132), reducing the probability of fluid leakage from this docking portion.

[0042] Refer to Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 6 in which the first position is shown as X, Figure 7 and the second position is shown as Y in . The sealing portion (132) may specifically include a sealing ring (133). The sealing ring (133) is provided with a through hole (134) corresponding to the first opening (112) and the second opening (122), and the through hole (134) can communicate the first opening (112) and the second opening (122).

[0043] Optionally, the seat body (11) may specifically further be provided with a ring groove (113) surrounding the periphery of the first opening (112), and the sealing ring (133) can be limited in the ring groove (113). And in the direction of docking of the first opening (112) and the second opening (122), at least a part of the sealing ring (133) is exposed outside the ring groove (113), so as to be in abutting fit with the surface of the separator (12) on the periphery of the second opening (122). When the first flow channel (111) is communicated with the second flow channel (121), the sealing ring (133) can seal the docking portion, preventing the fluid in the first flow channel (111) and the second flow channel (121) from leaking to the outside through the docking portion thereof. When the separator (12) is in the second position relative to the seat body (11), the second opening (122) does not dock with the through hole (134), and one side of the sealing ring (133) facing the separator (12) can abut against the surface of the separator (12), thereby isolating the first flow channel (111) from the second flow channel (121), and preventing the fluid in the first flow channel (111) from leaking to the outside through the first opening (112).

[0044] Specifically, the separator (12) may include a first mating portion (22). When the separator (12) is in the second position relative to the seat body (11), one side of the sealing ring (133) abuts against the first mating portion (22), and the other side abuts against the ring groove (113), thereby isolating the first flow channel (111) from the second flow channel (121).

[0045] Optionally, the sealing ring (133) may be made of a flexible material such as silica gel.

[0046] Refer to Figure 5, the sealing ring (133) may specifically include multiple concentric and spaced convex rings (135), and a sealing groove (136) is formed between adjacent convex rings (135). Among them, the first limiting structure (131) may be arranged on the inner wall of the sealing groove (136), and the second limiting structure (2) may extend into the sealing groove (136) to cooperate with the first limiting structure (131), so as to utilize the convex rings (135) on both sides of the sealing groove (136) to improve the structural stability of the sealing ring (133) while improving the sealing performance of the sealing member (13) at the docking part of the first flow channel (111) and the second flow channel (121).

[0047] Optionally, the number of the first flow channel (111), the second flow channel (121), and the sealing part (132) corresponds, and the number of all three can be at least two. In this embodiment, the sealing member (13) may further include a connecting part (137), the sealing parts (132) are connected through the connecting part (137), and the first limiting structure (131) is arranged on the connecting part (137). By connecting multiple sealing parts (132) through the connecting part (137), a connection relationship is established between the multiple sealing parts (132), and the sealing parts (132) can be relatively fixed to each other, thereby reducing the probability of fluid leakage caused by the displacement of a certain sealing part (132), which is beneficial to improving the sealing performance of the sealing part (132).

[0048] Furthermore, the number of the connecting parts (137) can be two, and the two connecting parts (137) are respectively located on the opposite sides of the sealing part (132). So that the overall structure is more stable. And, the two connecting parts (137) may further include arc-shaped connecting parts, and the arc-shaped connecting parts can be tangent to the contour of the sealing ring (133), which can make the overall structure of the sealing member (13) more stable and have better sealing performance.

[0049] Optionally, the moving mode of the isolating member (12) relative to the seat body (11) can be translational movement or rotational movement.

[0050] When the moving mode of the isolating member (12) between the first position and the second position is rotational movement, the connecting part (137) can be centered on the axis of rotation of the isolating member (12) rotating, so as to better adapt to the rotational movement of the isolating member (12). At this time, the first matching part (22), the first opening (112), the second opening (122), the sealing part (132), and the arc-shaped connecting part can be arranged on the same arc centered on the axis of rotation of the isolating member (12) rotating. During the process of the isolating member (12) rotating from the second position to the first position, the structure of the sealing part (132) docking with the first opening (112) gradually changes from the first matching part (22) to the second opening (122).

[0051] Optionally, refer to Figure 10 , Figure 10The first position is shown as X, and the second position is shown as Y. Figure 10 This is a schematic structural view of the separator provided by the embodiment of the present invention in the second position. The first limiting structure (131) may include one of the elastic flap (4a) and the plug-in member (4b), and the second limiting structure (2) may include the other of the elastic flap (4a) and the plug-in member (4b). The plug-in member (4b) is arranged along the direction from the second position to the first position, and the elastic flap (4a) includes a valve flap (41a) and a jack (42a).

[0052] Wherein, when the separator (12) is located at the second position relative to the seat body (11), the valve flap (41a) naturally closes so that the jack (42a) is closed, and the first flow channel (111) and the second flow channel (121) are isolated on both sides of the elastic flap (4a). During the process of the separator (12) moving from the second position to the first position, the plug-in member (4b) gradually abuts against the valve flap (41a) in the direction close to the first opening (112) on the side facing the seal member (13). The valve flap (41a) undergoes elastic deformation under the action of the plug-in member (4b), so that the jack (42a) becomes larger until the plug-in member (4b) can be inserted into the jack (42a). When the separator (12) is located at the first position, the plug-in member (4b) is inserted into the jack (42a), and the valve flap (41a) on the periphery of the jack (42a) abuts against the surface of the plug-in member (4b) under the elastic action, so that the connected first flow channel (111) and the second flow channel (121) are both isolated from the outside.

[0053] By using the method provided in this embodiment, the connection and isolation of the first flow channel (111) and the second flow channel (121) can be realized through the elastic deformation of the elastic flap (4a), and the valve flap (41a) can abut against the plug-in member (4b) under the elastic action, and the plug-in member (4b) is limited by the frictional force, so as to improve the stability of the butt joint between the first flow channel (111) and the second flow channel (121).

[0054] Refer to Figure 11 , Figure 11 This is another schematic structural view of the separator provided by the embodiment of the present invention in the second position. Figure 11The first position is shown as X, and the second position is shown as Y. The second limiting structure (2) may further include a plug-in portion (21). The plug-in portion (21) is disposed on the spacer (12) around the second opening (122) and / or the inner wall of the second opening (122). The first limiting structure (131) may be disposed on the inner wall of the through hole (134). When the spacer (12) is in the first position relative to the seat body (11), the plug-in portion (21) can be inserted into the through hole (134) and cooperate with the first limiting structure (131). Thus, the spacer (12) is limited to the first position by the limiting relationship between the first limiting structure (131) and the plug-in portion (21), improving the docking stability between the first opening (112) and the second opening (122).

[0055] Specifically, the plug-in portion (21) may include a sleeve (212) disposed around the second opening (122) and a buckle (213) disposed on the outer peripheral surface of the sleeve (212). The second limiting structure (2) may be a groove disposed on the inner wall of the through hole (134). When the spacer (12) is in the second position relative to the seat body (11), the valve flap (41a) of the seal (13) naturally closes to seal the jack (42a), thereby isolating the first flow channel (111) from the second flow channel (121). When the spacer (12) moves to the first position relative to the seat body (11), the valve flap (41a) is separated under the action of the plug-in portion (21), causing the jack (42a) to open. The sleeve (212) is inserted into the through hole (134), and the first flow channel (111) and the second flow channel (121) can communicate through the sleeve (212), and the buckle (213) can be engaged and cooperate with the first limiting structure (131), improving the docking stability between the first flow channel (111) and the second flow channel (121).

[0056] Optionally, in the direction from the second position to the first position, the dimensions of the buckle (213) and the sleeve (212) perpendicular to this direction can gradually decrease, thereby forming a guiding surface (211) towards the first position to guide the movement of the spacer (12) from the second position to the first position.

[0057] Optionally, as Figure 8 、 9 shown Figure 8 the first position is shown as X Figure 9 and the second position is shown as Y Figure 8 Another schematic diagram of the cooperation structure of the spacer provided by the embodiment of the present invention in the first position. Figure 9 is Figure 8Schematic diagram of the mating structure of the middle spacer in the second position. The first limiting structure (131) may specifically include one of the hook (3a) and the slot (3b), and the second limiting structure (2) may include the other of the hook (3a) and the slot (3b). Among them, the hook (3a) enters the slot (3b) along the direction from the second position to the first position, so as to be engaged and mated with the slot (3b). The first limiting structure (131) and the second limiting structure (2) provided in this embodiment can limit the spacer (12) when the spacer (12) is located at the first position relative to the seat body (11) through the mating relationship between the hook (3a) and the slot (3b), thereby improving the stability when the first flow channel (111) is docked with the second flow channel (121).

[0058] Specifically, the seal (13) may further include a second mating portion (3c), and the second mating portion (3c) is provided corresponding to the second position. When the spacer (12) is located at the second position relative to the seat body (11), the side surface of the spacer (12) where the second opening (122) is provided abuts against the second mating portion (3c), and the second mating portion (3c) is used to block the second opening (122) to isolate the first flow channel (111) from the second flow channel (121).

[0059] Further, as Figure 8 、 9 shown, the hook (3a) may be provided in two along the first position to the second position. When the spacer (12) moves to the second position, the slot (3b) on the side close to the second position can cooperate with the hook (3a) on the side close to the first position to limit the spacer (12) at the second position. Improve the usability of the first limiting structure (131) and the second limiting structure (2), so that they can be used simultaneously to improve the stability of the docking and isolation of the first flow channel (111) and the second flow channel (121).

[0060] Optionally, referring to Figure 6 、 7 , the first limiting structure (131) and the second limiting structure (2) can also be magnetically mated. Among them, the first limiting structure (131) and the second limiting structure (2) have opposite polarities, so that when the first limiting structure (131) approaches the second limiting structure (2), the two can attract each other, thereby relatively fixing the first limiting structure (131) and the second limiting structure (2) by magnetic attraction. When the spacer (12) is located at the second position relative to the seat body (11), the side surface of the spacer (12) where the second opening (122) is provided abuts against the second mating portion (3c), thereby using the second mating portion (3c) to block the second opening (122) to isolate the first flow channel (111) from the second flow channel (121).

[0061] Further, the first limiting structure (131) and the second limiting structure (2) can be electromagnets, metal magnets, etc.

[0062] Further, the first limiting structure (131) can be arranged in two from the first position to the second position. When the separator (12) moves to the second position, the second limiting structure (2) on the side close to the second position can be magnetically coupled with the first limiting structure (131) on the side close to the first position to limit the separator (12) at the second position. This enables the first limiting structure (131) and the second limiting structure (2) to not only function when the first flow channel (111) is docked with the second flow channel (121), but also improve the stability of the isolation state between the first flow channel (111) and the second flow channel (121).

[0063] As Figure 1 shown, the present application also provides a fluid processing device. The fluid processing device includes a filter element (5) and a filter element seat (1) as described in any one of the above embodiments, and the filter element (5) is detachably fixed to the filter element seat (1). Among them, the fluid can flow into and out of the filter element (5) through the filter element seat (1), so that the fluid processing device can input the fluid into the filter element (5) through the filter element seat (1), use the filter element (5) to process the input fluid, and output the processed fluid through the filter element seat (1). The fluid processing device provided in this embodiment relatively fixes the separator (12) and the seat body (11) through a seal (13), reducing the probability of relative displacement between the separator (12) and the seat body (11) due to factors such as water flow, improving the stability of the docking or isolation between the first flow channel (111) and the second flow channel (121), and thus improving the usability of the fluid processing device.
