Description

Technical Field

[0001] The present application relates to the field of bathroom technology, and in particular to a filter element assembly and a bathroom device. Background Art

[0002] Smart toilets are now popular on the market with functions such as flushing the buttocks, drying, and deodorizing. Currently, water directly entering the water supply system usually contains impurities. If these impurities are not filtered, the service life of the boosting equipment will be reduced or even damaged.

[0003] In the related art, a filter device is usually added to the smart toilet to filter the incoming water. The filter device is generally composed of a filter element and a mounting assembly. After the filter element is fixed by the mounting assembly, the incoming water can be filtered by the filter element.

[0004] Since the filter element has a limited amount of water to filter, it needs to be replaced after long-term continuous operation. However, in related technologies, the water supply needs to be stopped when the filter element is replaced or removed, which will cause the toilet to be unable to be used normally, seriously affecting the user's use. Utility Model Content

[0005] The present application provides a filter element assembly and a bathroom fixture to solve the problem that a toilet cannot be used normally when the filter element is replaced or removed.

[0006] In the first aspect, the present application provides a filter element assembly, comprising a barrel assembly, a filter element body and a valve core.

The filter element body is provided in the inner cavity of the barrel assembly, and comprises a water inlet and a water outlet. The valve core is provided in the connecting channel, and the valve core slides along the axial direction of the connecting channel between the first position and the second position. In the state of the first position, the water inlet channel is connected to the water inlet of the filter element body, and the water outlet of the filter element body is connected to the water outlet channel; in the state of the second position, the water inlet channel and the water outlet channel are connected.

[0007] Beneficial Effects: This filter cartridge assembly allows the replacement or removal of the filter cartridge without stopping the water supply, thus avoiding the problem of the toilet being unable to function normally due to filter cartridge replacement, greatly improving the user experience. Specifically, the filter cartridge assembly connects or disconnects the filter cartridge body with the water inlet and outlet channels by sliding the valve core within the connecting channel, thus ensuring the continuity of the water supply while enabling convenient replacement of the filter cartridge.

[0008] In an optional embodiment, the water outlet channel includes a first water outlet channel and a second water outlet channel. When the valve core is in the first position, the valve core is against the filter element body, so that the first end of the connecting channel is connected to the water inlet of the filter element body, and the water outlet of the filter element body is connected to the first water outlet channel. When the valve core is in the second position, the valve core is disengaged from the filter element body, so that the second end of the connecting channel is connected to the second water outlet channel.

[0009] Beneficial Effect: When the valve core is in the first position, the valve core and the filter body are in contact, and the filter body is connected to the water inlet channel and the first water outlet channel. In this case, the water flows in the direction of the water inlet channel, the connecting channel, the filter body, and the first water outlet channel. When the valve core is in the second position, the valve core is separated from the filter body, the water inlet channel is connected to the second water outlet channel, and the water flows in the direction of the water inlet channel, the connecting channel, and the second water outlet channel.

[0010] In an optional embodiment, the water outlet channel includes a second water outlet channel, and when the valve core is in the first position, the valve core is against the filter element body, the first end of the connecting channel is connected to the water inlet of the filter element body, and the water outlet of the filter element body is connected to the second water outlet channel; when the valve core is in the second position, the valve core is disengaged from the filter element body, so that the second end of the connecting channel is connected to the second water outlet channel.

[0011] Beneficial Effects: When the valve core is in the first position, it abuts against the filter body, connecting the water inlet channel and the second water outlet channel. The water flows in the following directions: the water inlet channel, the connecting channel, the filter body, and the second water outlet channel. When the valve core is in the second position, it disengages from the filter body, connecting the water inlet channel and the second water outlet channel. The water flows in the following directions: the water inlet channel, the connecting channel, and the second water outlet channel.

[0012] In an optional embodiment, the valve core includes a piston, a rod body, a spring and a limit block.

[0014] The first end of the rod body is connected to the piston, a limiting cylinder is provided in the inner cavity of the cylinder assembly, and the second end of the rod body extends into the inner cavity of the limiting cylinder and is in sliding contact with the inner wall of the limiting cylinder.

[0015] The spring is sleeved on the limiting cylinder, the first end of the spring abuts against the piston, the second end of the spring abuts against the inner wall of the inner cavity of the cylinder assembly, and the spring has a tendency to drive the piston away from the limiting cylinder.

[0016] The first end of the limit block is connected to one end of the piston facing the filter element body, the second end of the limit block is against the filter element body, and the first end and the second end of the limit block are arranged opposite to each other along the axial direction of the connecting channel.

[0017] Beneficial Effects: Through the coordination of the piston, rod, spring, and stopper, the valve core can slide stably between the first and second positions. This sliding process is smooth and reliable, effectively avoiding water supply problems caused by unstable valve core movement. Furthermore, the spring configuration enables the valve core to automatically return to its initial position when no external force is applied, thus ensuring the stability and reliability of the filter element assembly.

[0018] In an optional embodiment, a limit plate is provided in the connecting channel, a limit hole is provided on the limit plate, the limit block passes through the limit hole and abuts against the filter element body, and a connecting hole is provided on the limit plate, the connecting hole passing through the limit plate along the axial direction of the connecting channel. When the valve core is in the first position, the piston abuts against the limit cylinder; when the valve core is in the second position, the piston abuts against the limit plate.

[0019] Beneficial Effects: The provision of the limiting plate and limiting hole further restricts the movement trajectory of the valve core, preventing it from deviating from the predetermined path during sliding, thereby ensuring the normal operation of the filter element assembly. Simultaneously, the provision of the connecting hole enables the connection between the connecting channel and the inner cavity of the cylinder, ensuring that water entering from the water inlet channel can pass into the filter element body for filtration.

[0020] In an optional embodiment, the filter element body includes an inner tube, an outer tube, a plug, a first filter layer and a second filter layer.

[0021] The outer cylinder is sleeved on the outside of the inner cylinder, and the inner cylinder and the outer cylinder are coaxially arranged.

[0022] Beneficial Effects: The filter element achieves dual filtration through the configuration of the inner and outer cylinders, effectively improving the filtration effect. At the same time, the gap between the inner and outer cylinders and the filter layer in the inner cylinder cavity can be set with filter materials of different filtration accuracies as needed to meet different filtration needs.

[0023] In an optional embodiment, the outer cylinder is plugged into the inner wall of the cylinder assembly, the gap is connected to the water outlet channel, and when the valve core is in the first position, the filter element body is connected to the water inlet channel and the water outlet channel.

[0040] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0041] The following combination Figures 1 to 6 , describing the embodiments of the present application.

[0042] According to an embodiment of the present application, on the one hand, a filter element assembly is provided, including a barrel assembly, a filter element body 7 and a valve core 8.

[0043] The barrel assembly has an internal cavity, with a water inlet channel 3 and a water outlet channel defined on its sidewalls. A connecting channel 2 communicating with the water inlet channel 3 is located within the internal cavity of the barrel assembly. A filter element body 7, comprising a water inlet and a water outlet, is disposed within the internal cavity of the barrel assembly. A valve core 8 is disposed within the connecting channel 2 and slides axially along the connecting channel 2 between a first position and a second position. In the first position, the water inlet channel 3 communicates with the water inlet of the filter element body 7, and the water outlet of the filter element body 7 communicates with the water outlet channel. In the second position, the water inlet channel 3 communicates with the water outlet channel.

[0044] In this embodiment, the filter cartridge assembly enables filter cartridge replacement or removal without interrupting water supply, thus avoiding the problem of toilet failure due to filter cartridge replacement and greatly improving the user experience. Specifically, the filter cartridge assembly connects or disconnects the filter cartridge body 7 with the water inlet channel 3, the first water outlet channel 4, and the second water outlet channel 6 through the sliding of the valve core 8 within the connecting channel 2, thereby ensuring the continuity of water supply while enabling convenient filter cartridge replacement.

[0045] In some embodiments, the barrel assembly includes a barrel 1 and an end cap 5. The barrel 1 is provided with a connecting channel 2. The outer wall of the barrel 1 is provided with a water inlet channel 3 and a first water outlet channel 4. The water inlet channel 3 is connected to the inner cavity of the connecting channel 2, and the first water outlet channel 4 is connected to the inner cavity of the barrel 1. The end cap 5 is provided with a sink. The second end outer wall of the barrel 1 closes the sink, and the connecting channel 2 connects the inner cavity of the barrel 1 and the sink. The outer wall of the end cap 5 is provided with a second water outlet channel 6, which is connected to the sink.

[0046] Optionally, the water outlet channel includes a first water outlet channel 4 and a second water outlet channel 6. When the valve core 8 is in the first position, the valve core 8 is against the filter element body 7, so that the first end of the connecting channel 2 is connected to the water inlet of the filter element body 7, and the water outlet of the filter element body 7 is connected to the first water outlet channel 4. When the valve core 8 is in the second position, the valve core 8 is disengaged from the filter element body 7, so that the second end of the connecting channel 2 is connected to the second water outlet channel 6.

[0047] Optionally, the water outlet channel includes a second water outlet channel 6. When the valve core 8 is in the first position, the valve core 8 abuts against the filter element body 7, the first end of the connecting channel 2 communicates with the water inlet of the filter element body 7, and the water outlet of the filter element body 7 communicates with the second water outlet channel 6. When the valve core 8 is in the second position, the valve core 8 disengages from the filter element body 7, allowing the second end of the connecting channel 2 to communicate with the second water outlet channel 6. In this optional embodiment, the first water outlet channel 4 is not required.

[0048] The first end of the cylinder 1 may be provided with an opening, and the second end may be provided with a connecting channel 2. The first and second ends of the cylinder 1 may be arranged relative to each other along the axial direction of the cylinder 1. A water inlet channel 3 and a first water outlet channel 4 are provided on the outer wall of the cylinder 1, and the first water outlet channel 4 is connected to the inner cavity of the cylinder 1. An end cap 5 is provided at the second end of the cylinder 1, and the end cap 5 is provided with a sink. The outer wall of the second end of the cylinder 1 closes the sink, and the connecting channel 2 connects the inner cavity of the cylinder 1 and the sink. A second water outlet channel 6 is provided on the outer wall of the end cap 5, and the second water outlet channel 6 is connected to the sink. A filter element body 7 is provided in the cylinder 1 through the opening, and the filter element body 7 can be unloaded from the cylinder 1 through the opening. A valve core 8 is provided in the connecting channel 2, and the valve core 8 slides between a first position and a second position along the axial direction of the connecting channel 2. The water inlet channel 3 is connected to the inner cavity of the connecting channel 2, so that the water entering the water inlet channel 3 first flows into the connecting channel 2, and then changes the position of the valve core 8 in the connecting channel 2, so that the water in the connecting channel 2 can flow toward the inner cavity of the cylinder 1 or the sink direction respectively.

[0049] When the valve core 8 is in the first position, the valve core 8 abuts against the filter body 7, and the filter body 7 connects the water inlet channel 3 and the first water outlet channel 4. In this case, the water flow direction is specifically the water inlet channel 3, the connecting channel 2, the filter body 7, and the first water outlet channel 4. Alternatively, the filter body 7 connects the water inlet channel 3 and the second water outlet channel 6, and the water flow direction is specifically the water inlet channel 3, the connecting channel 2, the filter body 7, the sink, and the second water outlet channel 6. When the valve core 8 is in the second position, the valve core 8 is disengaged from the filter body 7, the water inlet channel 3 connects with the second water outlet channel 6, and the water flow direction is specifically the water inlet channel 3, the connecting channel 2, the sink, and the second water outlet channel 6.

[0050] It can be understood that the present application provides two types of clean water passages. One is to abut the filter element body 7 against the valve core 8, and push the valve core 8 to the end of the connecting cylinder 1 near the end cover 5 and seal it, so that the water entering the connecting channel 2 from the water inlet channel 3 can enter the filter element body 7 for filtration, and finally be discharged from the first water outlet channel 4. The second is to abut the filter element body 7 against the valve core 8, and push the valve core 8 to the end of the connecting cylinder 1 near the end cover 5 and seal it, so that the water entering the connecting channel 2 from the water inlet channel 3 can enter the filter element body 7 for filtration, and then pass through the connecting channel 2 and the cylinder 1 and enter the trough, and finally be discharged from the second water outlet channel 6. In addition, the different structures of the two clean water passages can both achieve normal water flow after the filter element body 7 is pulled out, that is, the unpurified water is uniformly discharged from the second channel, and the water flow path is the same.

[0051] It should be noted that after the filter element body 7 is inserted into the barrel 1, the filter element body 7 abuts against the valve core 8, allowing the valve core 8 to be in the first position and perform water purification. After the filter element body 7 is removed from the barrel 1, the valve core 8 returns to its second position. At this time, the valve core 8 is located on the side of the connecting channel 2 close to the filter element body 7, thereby blocking the connecting channel 2 and the inner cavity of the barrel 1, allowing water that has not been filtered by the filter element body 7 to flow directly from the water inlet channel 3 into the trough and be discharged through the second channel.

[0052] In some embodiments, the valve core 8 includes a piston 9 , a rod 10 , a spring 12 and a limit block 13 .

[0053] The cross-sectional shape of the piston 9 perpendicular to the axial direction of the connecting channel 2 is adapted to the cross-sectional shape of the inner cavity of the connecting channel 2. The outer circumferential surface of the piston 9 slides with the inner wall of the connecting channel 2, that is, the outer circumferential surface of the piston 9 always maintains a contact state with the inner wall of the connecting channel 2, which can ensure a sealing effect. The first end of the rod body 10 is connected to the end of the piston 9 facing the end cover 5. A limiting cylinder 11 is provided in the sink. The second end of the rod body 10 extends into the inner cavity of the limiting cylinder 11 and slides in contact with the inner wall of the limiting cylinder 11. The limiting cylinder 11 can limit the rod body 10 and restrict its displacement direction. The first and second ends of the rod body 10 can be arranged relative to each other along its axial direction. The spring 12 is sleeved on the limiting cylinder 11. The first end of the spring 12 abuts against the piston 9, and the second end of the spring 12 abuts against the bottom of the sink. The spring 12 has a tendency to drive the piston 9 away from the limiting cylinder 11. When the filter body 7 is installed in the cylinder 1, the filter body 7 presses the limiting block 13 downward, causing the piston 9 to move downward, putting the spring 12 in a compressed state. After the filter body 7 is removed, the spring 12 releases its elastic potential energy, which can reset the piston 9. The first end of the limiting block 13 is connected to the end of the piston 9 facing the filter body 7, and the second end of the limiting block 13 abuts against the filter body 7. The first and second ends of the limiting block 13 are arranged opposite each other along the axial direction of the connecting channel 2.

[0054] Optionally, a plurality of limit blocks 13 may be provided, and they may be arranged around the circumference of the piston 9 to make it more stable when in contact with the filter element body 7 , thereby avoiding tilting and hindering the movement of the piston 9 .

[0055] Optionally, the limiting cylinder 11 and the connecting channel 2 can be coaxially arranged, and the maximum cross-sectional diameter of the limiting cylinder 11 perpendicular to its axial direction is smaller than the maximum cross-sectional diameter of the connecting channel 2 perpendicular to its axial direction, so as to avoid the limiting cylinder 11 blocking the connecting channel 2.

[0056] Optionally, the cross-sectional shape of the inner cavity of the connecting channel 2 and the limiting cylinder 11 perpendicular to the axial direction thereof can be set to a circular, quasi-circular or polygonal structure.

[0057] In this embodiment, the cooperation of piston 9, rod 10, spring 12, and stopper 13 allows valve core 8 to stably slide between the first and second positions. This sliding process is smooth and reliable, effectively avoiding water supply problems caused by unstable movement of valve core 8. Furthermore, the provision of spring 12 enables valve core 8 to automatically return to its initial position when no external force is applied, thereby ensuring the stability and reliability of the filter element assembly.

[0058] In some embodiments, a limit plate 14 is provided in the connecting channel 2, a limit hole is provided on the limit plate 14, a limit block 13 passes through the limit hole and abuts against the filter element body 7, a connection hole 15 is provided on the limit plate 14, and the connection hole 15 passes through the limit plate 14 along the axial direction of the connecting channel 2, and the connection hole 15 can achieve a connection effect. The limit plate 14 can limit the displacement distance of the piston 9 to prevent it from detaching from the connecting channel 2. In the first position, the filter element body 7 and the limit plate 14 abut against each other, and the piston 9 is detached from the limit plate 14. The water entering from the water inlet channel 3 passes through the connection hole 15 between the multiple limit blocks 13 and enters the filter element body 7 for filtration. In the second position, the piston 9 abuts against the limit plate 14.

[0059] Optionally, under the limiting effect of the limiting block 13 and the limiting hole, a gap may exist between the limiting cylinder 11 and the rod body 10, and the spring 12 may be arranged in the gap.

[0060] Optionally, the limiting block 13 may be provided with a cylindrical structure having a notch 18 , and the limiting hole may be provided with a corresponding arc-shaped structure.

[0061] In this embodiment, the provision of the limiting plate 14 and the limiting hole further restricts the movement trajectory of the valve core 8, preventing the valve core 8 from deviating from the predetermined path during sliding, thereby ensuring the normal operation of the filter element assembly. Simultaneously, the provision of the connecting hole 15 establishes communication between the connecting channel 2 and the inner cavity of the barrel 1, ensuring that water entering through the water inlet channel 3 can pass into the filter element body 7 for filtration.

[0062] In some embodiments, the filter element body 7 includes an inner tube 16 , an outer tube 17 , a plug 19 , a first filter layer 20 and a second filter layer 21 .

[0063] Outer cylinder 17 is sleeved outside inner cylinder 16, and the two cylinders are coaxially arranged, with a gap between them. A notch 18 is provided on the outer circumference of the first end of inner cylinder 16, connecting the gap with the inner cavity of inner cylinder 16. The second end of inner cylinder 16 serves as a water inlet, which connects inner cylinder 16 to connecting channel 2. The gap communicates with the inner cavity of cylinder body 1, and the end of the gap away from the notch serves as a water outlet. A plug 19 abuts the first end of inner cylinder 16 and seals the first end of outer cylinder 17. A first filter layer 20 is disposed within the inner cavity of inner cylinder 16, and a second filter layer 21 is disposed within the gap.

[0064] Optionally, the first filter layer 20 and the second filter layer 21 may be made of one or both of an activated carbon layer and a PP cotton layer.

[0065] In this embodiment, the filter element body 7 achieves dual filtration through the arrangement of the inner cylinder 16 and the outer cylinder 17, effectively improving the filtration effect. Furthermore, the gap between the inner and outer cylinders 16, 17, and the filter layer within the inner cylinder 16 cavity allow for the installation of filter materials with varying filtration accuracies as needed to meet diverse filtration requirements.

[0066] Reference Figure 1-Figure 3 In some embodiments, the outer cylinder 17 is plugged into the cylinder body 1, the gap is connected to the first water outlet channel 4, the valve core 8 is in the first position, the filter element body 7 is connected to the water inlet channel 3 and the first water outlet channel 4, and the water flowing out of the gap is directly discharged through the first water outlet channel 4.

[0067] In this embodiment, when the filter element body 7 is connected to the first water outlet channel 4, the water entering the toilet can be filtered, thereby ensuring the quality of the water used in the toilet.

[0068] Reference Figure 4-Figure 6 In some embodiments, a through hole is provided on the second end of the cylinder 1, connecting the sink and the inner cavity of the cylinder 1. A check plug 22 is disposed within the through hole, which is adapted to connect the inner cavity of the cylinder 1 and the sink in a direction from the cylinder 1 toward the end cap 5. The outer cylinder 17 is plugged into the cylinder 1, and the second end of the outer cylinder 17 seals the first water outlet channel 4. When the valve core 8 is in the first position, the filter element body 7 connects the water inlet channel 3 and the second water outlet channel 6.

[0069] Optionally, one side of the anti-return plug 22 is connected to the outer wall of the through hole at the side of the hole facing the sink. When the anti-return plug 22 is in the second position, the remaining portion can block the through hole under the action of the water pressure in the sink. When the anti-return plug 22 is in the first position, the anti-return plug 22 is deformed under the action of the water pressure in the inner cavity of the cylinder 1, making the through hole conductive.

[0070] In this embodiment, when the filter element body 7 is connected to the second water outlet channel 6, the water inside the toilet can be circulated and filtered, thereby further improving the water quality of the toilet. At the same time, the provision of the anti-return plug 22 also ensures the unidirectional flow of water, avoiding the problem of water backflow.

[0071] In some embodiments, a ring body 23 is provided in the gap, the outer circumference of the ring body 23 is connected to the inner circumference of the outer cylinder 17, and the inner circumference of the ring body 23 is connected to the outer circumference of the inner cylinder 16. A channel 24 is provided on the ring body 23, and the channel 24 passes through the ring body 23 along the axial direction of the ring body 23.

[0072] Optionally, the ring body 23 may be constructed as an integral structure with the inner cylinder 16 or the outer cylinder 17 to facilitate assembly of the filter element body 7 .

[0073] Optionally, the holes 24 are arranged at intervals along the circumference of the ring body 23 on the inner circumferential surface or the outer circumferential surface of the ring body 23 .

[0074] In this embodiment, the provision of the ring body 23 and the hole 24 achieves a stable connection between the inner tube 16 and the outer tube 17 and ensures that the water filtered by the first filter layer 20 and the second filter layer 21 can flow out through the hole 24 .

[0075] In some embodiments, the outer circumference of the outer cylinder 17 and the inner circumference of the cylinder body 1 are connected by threads.

[0076] Optionally, threads may be provided on both the outer circumference of the outer cylinder 17 and the inner circumference of the cylinder body 1 to achieve connection between the filter element body 7 and the cylinder body 1 , thereby ensuring a fixed position and achieving a sealing effect.

[0077] In this embodiment, the outer cylinder 17 is threadedly connected to the cylinder body 1, allowing the filter element body 7 to be easily installed and removed, thereby facilitating filter element replacement and maintenance. The plug 19 also serves as a handle to facilitate twisting the filter element body 7 for removal and installation.

[0078] In some embodiments, the end cover 5 is connected to the cylinder 1 by bolts.
