Filter element device

Abstract

The utility model discloses a filter element device, and belongs to the technical field of water purification equipment. A waterway adapter in the filter element device is in sliding connection with a waterway seat along a target direction, and the waterway adapter is used for being connected with a waterway plate in the water purification equipment. Thus, when the filter element needs to be detached and replaced, an operator rotates the handle part in one direction, and the water path adapter is driven by the transmission assembly to move in the target direction and the direction away from the water path plate in the rotating process of the handle part, so that the water path adapter is separated from the water path plate. When the filter element needs to be connected with a water path plate in the water purification equipment, an operator rotates the handle part in the opposite direction, and the water path adapter is driven by the transmission assembly to move in the target direction and the direction close to the water path plate in the rotating process of the handle part, so that installation, namely water path connection, of the water path adapter and the water path plate is achieved. Therefore, when the filter element device is disassembled from the water purification equipment by adopting the structure, only the handle piece needs to be rotated to be matched with the waterway adapter, the whole weight of the filter element does not need to be borne, and the disassembly is easy and labor-saving.

Description

Filter cartridge device Technical Field

[0001] This application relates to the field of water purification equipment technology, and in particular to a filter cartridge device. Background Technology

[0002] Water purification equipment generally consists of a filter cartridge and a main unit. The filter cartridge is installed in the main unit and connects to the water circuit board, enabling it to perform its filtration function properly. The filtration capacity of the filter cartridge decreases with use, so it generally needs to be replaced after a period of use.

[0003] When installing the current filter cartridge, first place the filter cartridge into the filter cylinder, and then rotate the filter cartridge clockwise to connect the bottom of the filter cartridge to the water circuit board. When you need to remove the filter cartridge, you need to rotate the filter cartridge counterclockwise to disassemble it from the water circuit board, and then take the filter cartridge out of the filter cylinder.

[0004] However, the filter element becomes heavier after water is introduced, and the interaction force between the filter element and the water circuit board increases, making it difficult for the filter element to rotate. Summary of the Invention

[0005] This application provides a filter cartridge device. It solves the problem in the prior art where the filter cartridge's weight is too large after water flow, making rotation difficult. The technical solution is as follows:

[0008] One end of the filter bottle assembly has a water channel seat;

[0009] The water circuit adapter is located on top of the water channel seat and has a water channel hole extending along the target direction. The first end of the water circuit adapter is slidably connected to the water channel seat along the target direction, and the second end is used for detachable connection with the water circuit board of the water purification equipment. The target direction is parallel to the radial direction of the filter bottle assembly.

[0010] The transmission assembly is distributed between the top of the water channel seat and the handle, and is connected to the water channel adapter and the handle respectively; the handle is rotatably connected to the filter bottle assembly.

[0011] The handle is configured such that, during rotation relative to the filter bottle assembly around its central axis, the transmission assembly drives the water circuit adapter to move, thereby causing the second end of the water circuit adapter to extend or retract.

[0012] Optionally, the transmission assembly includes: a gear, a rack, and a carrier, wherein the shaft of the gear is fixedly connected to the handle and the shaft of the gear is parallel to the central axis of the filter bottle assembly; the rack meshes with the gear and one end of the rack is fixedly connected to the carrier, and the carrier is fixedly connected to the water circuit adapter.

[0013] Optionally, the carrier has a mounting groove and an opening communicating with and facing the mounting groove; the circumferential side of the water channel adapter has a mounting plate, and the mounting plate is installed into the mounting groove through the opening;

[0014] The carrier can move synchronously with the mounting plate during its movement.

[0015] Optionally, the carrier includes: a first baffle, a second baffle, and a pin, wherein the two sides of the first baffle are fixedly connected to the ends of the second baffle and the rack, respectively, and the first baffle has a insertion hole; the second baffle has a sleeve hole for fitting a water circuit adapter.

[0016] Wherein, a portion of the pin passes through the insertion hole and is positioned opposite to the second baffle along the target direction, forming the mounting groove.

[0017] Optionally, the top of the waterway seat has a first guide extending along the target direction, and the support member has a second guide that cooperates with the first guide;

[0018] The first guide member and the second guide member slide relative to each other along the target direction.

[0019] Optionally, the filter element device further includes: an upper cover located between the water channel seat and the handle, the upper cover being fastened to the water channel seat, the side of the upper cover having a first through hole, and the top of the upper cover having a second through hole; the handle is rotatably connected to the upper cover;

[0020] At least a portion of the water channel adapter and the transmission assembly are located within the area enclosed by the upper cover and the water channel seat, and the second end of the water channel adapter can extend and retract through the first through hole; a portion of the transmission assembly passes through the second through hole and is securely connected to the handle.

[0021] Optionally, the top cover has two first limiting portions arranged circumferentially on the side facing the handle, and the handle has a second limiting portion on the side facing the top cover;

[0022] When the handle is rotated to a first position relative to the top cover, the second limiting part engages with one of the first limiting parts; when the handle is rotated to a second position relative to the top cover, the second limiting part engages with another of the first limiting parts.

[0027] The beneficial effects of the technical solutions provided in this application include at least the following:

[0028] The water circuit adapter in the filter cartridge assembly is slidably connected to the water channel seat along the target direction. This adapter connects to the water circuit board in the water purification system. When the filter cartridge needs to be removed and replaced, the operator rotates the handle in one direction. During this rotation, a transmission component moves the water circuit adapter along the target direction away from the water circuit board, thus separating it from the board. When connecting the filter cartridge to the water circuit board, the operator rotates the handle in the opposite direction. This rotation, along with the transmission component, moves the adapter along the target direction towards the water circuit board, thus connecting it to the board. Therefore, with this structure, removing and installing the filter cartridge from the water purification system only requires rotating the handle and the water circuit adapter; the entire weight of the filter cartridge does not need to be supported, making installation and removal easy and effortless.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0043] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0044] Please refer to Figures 1 and 2. Figure 1 is a structural schematic diagram of a filter element device provided in an embodiment of this application, and Figure 2 is an exploded schematic diagram of a portion of the filter element device shown in Figure 1. The filter element device 000 may include: a filter bottle assembly 100, a water circuit adapter 200, a transmission assembly 300, and a handle 400.

[0045] One end of the filter bottle assembly 100 in the filter cartridge device 000 may have a water channel seat 101.

[0046] The water channel adapter 200 in the filter cartridge assembly 000 can be located on top of the water channel seat 101 and can have a water channel hole k1 extending along a target direction f. A first end of the water channel adapter 200 can be slidably connected to the water channel seat 101 along the target direction f, and a second end of the water channel adapter 200 can be detachably connected to the water circuit board (not shown) of the water purification device. The target direction f can be parallel to the radial direction of the filter bottle assembly 100. For example, the water channel adapter 200 includes a plurality of water pipes 201 arranged side-by-side, each water pipe 201 having a water channel hole k1 that communicates with the filter bottle assembly 100.

[0047] The transmission component 300 in the filter element device 000 can be distributed between the top of the water channel seat 101 and the handle 400, and is connected to the water channel adapter 200 and the handle 400 respectively. The handle 400 can be rotatably connected to the filter bottle assembly 100.

[0048] The handle 400 can be configured such that, during the rotation of the filter bottle assembly 100 relative to the filter bottle assembly 100 around the central axis L, the water channel adapter 200 is moved by the transmission assembly 300 to cause the second end of the water channel adapter 200 to extend and retract along the target direction f.

[0049] In this embodiment, the water path adapter 200 in the filter cartridge device 000 is slidably connected to the water channel seat 101 along the target direction f, and the water path adapter 200 is used to connect to the water channel plate in the water purification equipment. Thus, when the filter cartridge device needs to be disassembled and replaced, the operator rotates the handle 400 in one direction. During the rotation of the handle 400, the transmission assembly 300 drives the water path adapter 200 to move along the target direction f and away from the water channel plate, thereby separating it from the water channel plate. When it is necessary to connect the filter cartridge device 000 to the water channel plate in the water purification equipment, the operator rotates the handle 400 in the opposite direction. During the rotation of the handle 400, the transmission assembly 300 drives the water path adapter 200 to move along the target direction f and closer to the water channel plate, thereby achieving installation with the water channel plate, i.e., water path connection. Thus, when disassembling and assembling the filter element device 000 from the water purification equipment using the above structure, it is only necessary to rotate the handle 400 and the water circuit adapter 200 to cooperate, without having to bear the overall weight of the filter element, making disassembly and assembly easy and effortless.

[0050] In summary, this application provides a filter cartridge device, which may include: a filter bottle assembly, a water circuit adapter, a transmission assembly, and a handle. The water circuit adapter in the filter cartridge device is slidably connected to the water channel seat along a target direction, and the water circuit adapter is used to connect to the water circuit board in the water purification equipment. Thus, when the filter cartridge needs to be disassembled and replaced, the operator rotates the handle in one direction. During the rotation of the handle, the transmission assembly drives the water circuit adapter to move along the target direction and away from the water circuit board, thereby separating it from the water circuit board. When it is necessary to connect the filter cartridge to the water circuit board in the water purification equipment, the operator rotates the handle in the opposite direction. During the rotation of the handle, the transmission assembly drives the water circuit adapter to move along the target direction and closer to the water circuit board, thereby installing it with the water circuit board, i.e., connecting the water circuit. Therefore, when disassembling and assembling the filter cartridge device from the water purification equipment using the above structure, only the handle and the water circuit adapter need to be rotated; the entire weight of the filter cartridge does not need to be supported, making disassembly and assembly easy and effortless.

[0051] For example, please refer to Figure 3, which is a partially exploded schematic diagram of another filter element device provided in an embodiment of this application. The filter bottle assembly 100 may include a filter bottle 102 and a water channel seat 101, which can be installed at the opening of the filter bottle 102. The water channel seat 101 may have a mounting hole k communicating with the filter bottle 101, and a water channel adapter 200 can be inserted into the mounting hole k, with the water channel hole k1 communicating with the filter bottle 102.

[0052] Optionally, as shown in Figure 3, the transmission component 300 in the filter cartridge device 000 may include a gear 301, a rack 302, and a support member 303. The shaft 301a of the gear 301 can be securely connected to the handle 400, and the shaft 301a of the gear 301 can be parallel to the central axis L of the filter bottle assembly 100. The rack 302 can mesh with the gear 301, and one end of the rack 302 can be fixedly connected to the support member 303. The support member 303 can be securely connected to the water circuit adapter 200. In this case, using a relatively simplified gear and rack transmission mechanism, rotating the filter cartridge handle 400 drives the gear 301 to rotate forward and backward, thereby enabling the rack 302 and the support member 303 to drive the water circuit adapter 200 to reciprocate, realizing the connection and disconnection of the water circuit between the filter cartridge device 000 and the water circuit board in the water purification equipment. It should be noted that the rack 302 and the support member 303 can be an integral structure.

[0053] For example, please refer to Figure 4, which is a partial structural cross-sectional view of a filter element device provided in an embodiment of this application. In one possible implementation, the handle 400 may include a handle body 401 and a handle cover 402. A portion of the handle body 401 is protruding and may have a cavity Q1, and a connection hole k2 communicating with the cavity Q1 is located at the bottom. The handle cover 402 can be used to cover the cavity Q1. The end of the shaft 301a of the gear 301 can extend into the cavity Q1 through the connection hole k2 and be securely connected to the handle body 401. Thus, the operator can squeeze the handle body 401 to rotate the handle 400. For example, the end of the shaft 301a of the gear 301 can be securely connected to the inner bottom wall of the cavity Q1 of the handle body 401 by a first screw A.

[0054] For example, please refer to Figure 5, which is an exploded view of a partial structure of another filter element device provided in an embodiment of this application. In another possible implementation, the top of the handle 400 has a recess 403 and a clamping portion 404 fixed within the recess 403. The handle 400 may also have a first connecting hole k3 penetrating the clamping portion 404. The end of the shaft 301a of the gear 301 can extend into the first connecting hole k3 and be fastened to the handle 400. For example, the end of the shaft 301a of the gear 301 can be fastened to the edge portion of the top of the clamping portion 404 located in the first connecting hole k3 by a second screw B.

[0055] It should be noted that, in order to ensure the appearance of the handle 400, the clamping part 404 may have a countersunk hole k4 communicating with the first connecting hole k3. The inner diameter of the countersunk hole k4 is larger than the inner diameter of the first connecting hole k3. One end of the second screw B can pass through the countersunk hole k4 and the first connecting hole k3 in sequence and be fastened to the rotating shaft 301a of the gear 301. The other end of the second screw B may be located inside the countersunk hole k4.

[0056] In this embodiment, as shown in FIG3, the carrier 303 in the transmission assembly 300 may have a mounting groove 303a and an opening 303b communicating with the mounting groove 303a. The circumferential side of the water channel adapter 200 may have a mounting plate 202, which can be installed into the mounting groove 303a of the carrier 303 through the opening 303b. During the movement of the carrier 303, the mounting plate 202 can be moved synchronously. In this case, by providing the mounting groove 303a in the carrier 303 of the transmission assembly 300, and after the mounting plate 202 on the circumferential side of the water channel adapter 200 is installed in the mounting groove 303a through the opening 303b, the water channel adapter 200 can be moved by the gear and rack driving the carrier 303 to move. This ensures convenient assembly of the transmission assembly 300 and the water channel adapter 200, improving the assembly and disassembly efficiency of the filter element device 000.

[0057] In this application, please refer to Figures 3 and 6. Figure 6 is an exploded view of a partial structure of another filter element device provided in an embodiment of this application. The carrier 303 may include: a first baffle 3031, a second baffle 3032, and a pin 3033. The two sides of the first baffle 3031 can be fixedly connected to the ends of the second baffle 3032 and the rack 302, respectively. The first baffle 3031 has a insertion hole k5, and the second baffle 3032 has a socket hole k6 for connecting the water circuit adapter 200. A portion of the pin 3033 can pass through the insertion hole k5 and be positioned opposite the second baffle 3032 along the target direction f to form a mounting groove 303a. For example, during the assembly of the transmission component 300 and the water channel adapter 200, the second baffle 3032 is sleeved onto the water channel adapter 200 through the socket k6, and the second baffle 3032 can contact one side of the mounting plate 202; a portion of the pin 3033 is inserted into the other side of the mounting plate 202 through the insertion hole k5 on the first baffle 3031 and contacts the mounting plate 202. This facilitates the assembly and positioning of the carrier 303 and the water channel adapter 200, and allows users to repair and disassemble them themselves, improving ease of use.

[0058] It should be noted that when the water pipe adapter 200 includes multiple water pipes 201, the mounting plate 202 is used to connect the multiple water pipes 201, and the second baffle 3032 has socket holes k6 that correspond one-to-one with the multiple water pipes 201. For example, the first baffle 3031 may have multiple insertion holes k5 arranged in an array, and the pin 3033 may have multiple comb teeth C corresponding one-to-one with the multiple insertion holes k5. The multiple comb teeth C are arranged opposite to the second baffle 3032 along the target direction f, and the mounting plate 202 is inserted between the second baffle 3032 and the multiple comb teeth C. A water pipe 201 is distributed between every two adjacent comb teeth C.

[0059] Optionally, as shown in Figure 6, the top of the water channel seat 101 may have a first guide member 101a extending along the target direction f, and the carrier member 303 may have a second guide member 303b that cooperates with the first guide member 101a. The first guide member 101a and the second guide member 303b slide relative to each other along the target direction f. In this case, the guiding and limiting effect of the first guide member 101a and the second guide member 303b improves the stability and accuracy of the carrier member 303 during movement, further improving the assembly and disassembly efficiency of the filter element device 000.

[0060] For example, the first guide member 101a at the top of the water channel seat 101 can be a first strip-shaped guide groove, and the second guide member 303b in the support member 303 can be a first guide protrusion that slides in conjunction with the first strip-shaped guide groove. Alternatively, the first guide member 101a at the top of the water channel seat 101 can be a second guide protrusion, and the second guide member 303b in the support member 303 can be a second strip-shaped guide groove that slides in conjunction with the second guide protrusion.

[0061] In this embodiment of the application, as shown in Figures 3 and 4, the filter element device 000 may further include: an upper cover 500 located between the water channel seat 101 and the handle 400. The upper cover 500 can be fastened to the water channel seat 101. The side of the upper cover 500 may have a first through hole k7, and the top of the upper cover 500 may have a second through hole k8. The handle 400 can be rotatably connected to the upper cover 500. At least a portion of the water channel adapter 200 and the transmission assembly 300 can be located within the area enclosed by the upper cover 500 and the water channel seat 101. The second end of the water channel adapter 200 can extend and retract through the first through hole k7 in the upper cover 500, and a portion of the transmission assembly 300 can pass through the second through hole k8 in the upper cover 500 and be fastened to the handle 400. In this case, the connection between the upper cover 500 and the water channel seat 101 provides good protection for at least a portion of the water channel adapter 200 and the transmission assembly 300.

[0062] For example, in one possible implementation, as shown in Figure 3, the handle 400 is mounted on top of the cover 500 and is able to cover the top of the cover 500.

[0063] In another possible implementation, as shown in Figure 5, the top edge of the top cover 500 has a partially annular shielding protrusion 501, and the handle 400 can be located within the area enclosed by the annular shielding protrusion 501. This uses a recessed handle, reducing the overall height of the filter assembly and saving space.

[0064] Optionally, please refer to Figures 7, 8, and 9. Figure 7 is an exploded view of a handle and a top cover according to an embodiment of this application. Figure 8 is a bottom view of the handle in Figure 7. Figure 9 is an exploded view of another handle and a top cover according to an embodiment of this application. The side of the top cover 500 facing the handle 400 may have two first limiting portions 502 arranged circumferentially along the top cover 500. The side of the handle 400 facing the top cover 500 may have a second limiting portion D. When the handle 400 is rotated relative to the top cover 500 to a first position, the second limiting portion D in the handle 400 engages with one of the first limiting portions 502 in the top cover 500. When the handle 400 is rotated relative to the top cover 500 to a second position, the second limiting portion D in the handle 400 engages with the other first limiting portion 502 in the top cover 500. In this configuration, the cooperation of the two limiting parts enables a stable connection between the handle 400 and the upper cover 500, and limits the rotation angle of the handle 400 relative to the upper cover 500, thus improving ease of operation. It should be noted that in actual design requirements, the arrangement angle between the two first limiting parts can be set according to the travel of the rack after gear and rack engagement; this embodiment does not impose specific limitations on this.

[0065] In this application, one of the first limiting portion 502 in the upper cover 500 and the second limiting portion D in the handle 400 can be a limiting groove, and the other of the first limiting portion 502 in the upper cover 500 and the second limiting portion D in the handle 400 can be a limiting protrusion. Here, the extending directions of both the limiting groove and the limiting protrusion are parallel to the rotation shaft 301a of the gear 301. It should be noted that, in order to facilitate the engagement and disengagement of the limiting protrusion and the limiting groove, the edge regions of both the limiting protrusion and the limiting groove can be arc-shaped surfaces.

[0066] In this embodiment of the application, as shown in FIG5, the filter element device 000 may further include a handle 600, which is rotatably connected to the side of the upper cover 500. Thus, the handle 600 facilitates the handling and placement of the filter element device 000.

[0067] For example, as shown in Figure 5, when the top edge of the upper cover 500 has a partially annular shielding protrusion 501, the top of the upper cover 500 can have a relief groove 503 that matches the shape of the handle 600. The relief groove 503 can be arranged opposite to the annular shielding protrusion 501. When the handle 600 is folded, it can be located within the relief groove 503, which effectively improves the appearance of the filter element device 000.

[0068] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0069] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
