[0027] See also Figure 1 , Figure 1 It is a structural schematic diagram of an exploded view of the filtering device provided in this application.

[0028] The present application provides a filtering device, such as Figure 1As shown, the filter device 10 of this embodiment is disposed in a first water tank 20. The filter device 10 is partially disposed within the first water tank 20 and includes a housing 101 and a filter body 102 disposed within the housing 101. Specifically, the filter body 102 of the filter device 10 is located within the first water tank 20. The housing 101 of the filter device 10 may partially protrude from the first water tank 20. Therefore, when the filter device 10 filters the water within the first water tank 20, the filter body 102 can be fully used to filter the water flow within the first water tank 20, thereby improving the filtration efficiency of the filter device 10. The ends of the filter body 102 are sealed to the ends of the housing 101, forming an accommodating space 103 between the filter body 102 and the housing 101. Specifically, after the filter body 102 filters the water flow within the first water tank 20, the water flow can penetrate into the accommodating space 103 through the filter body 102, thereby completing the filtration of the water flow. One end of the filter body 102 passes through the housing 101 and communicates with the first water tank 20 . The housing 101 is provided with a water outlet 104 communicating with the accommodating space 103 .

[0029] In some embodiments, the filter device 10 is configured as a filter body 102 and a housing 101. When using the filter device 10, the filter body 102 can be slidably connected to the interior of the housing 101. When replacing the filter device 10, it is not necessary to completely remove the filter device 10 from the first water tank 20; only the filter body 102 needs to be removed from the housing 101. This makes assembly and disassembly of the filter device 10 more convenient when in use. Because one end of the filter body 102 passes through the housing 101 and communicates with the first water tank 20, the two ends of the filter body 102 are sealed to the two ends of the housing 101, thereby forming an accommodating space 103. After the water flows into the first water tank 20, the water flows through the filter body 102 and the end of the outer shell 101 connected to the first water tank 20 to enter the interior of the filter body 102. After entering the filter body 102, the water is filtered by the filter body 102 and penetrates into the accommodating space 103 formed between the outer shell 101 and the filter body 102. The outer shell 101 is provided with a water outlet 104 connected to the accommodating space 103, and the filtered water can be discharged through the water outlet 104.

[0030] Among them, the two ends of the filter body 102 are sealed with the two ends of the shell 101, so that the accommodating space 103 formed by the shell 101 and the filter body 102 can isolate the water flow in the accommodating space 103 from the water flow in the first water tank 20, reducing the possibility of the filtered water flow and the unfiltered water flow penetrating each other, which is conducive to ensuring that the unfiltered water flow enters the filtered water flow.

[0031] In a specific application scenario, the filter device 10 is set inside a toilet as an example. When the internal components of the toilet need to use water, the water can first be passed into the first water tank 20, and then filtered by the filter body 102 and seeped into the accommodating space 103. The filtered water in the accommodating space 103 is discharged through the water outlet 104. When the internal components of the toilet use water, it is beneficial to filter the dirt in the water, reduce the dirt deposition in the internal components, and cause damage to the internal components, which is beneficial to extend the service life of the internal components of the toilet and improve the user experience. In addition, the filter device 10 is set inside the toilet, and there is no need to connect other filters to the tap water connection outside the toilet, which effectively speeds up the installation efficiency of the toilet.

[0032] In this embodiment, since the filter device 10 needs to be replaced regularly when used for a long time, the filter device 10 in this application is directly installed in the toilet machine. When replacing the filter device 10, the filter body 102 can be taken out from the outer shell 101, and no special tools are required when disassembling and assembling the filter device 10, making the disassembly and assembly of the filter device 10 more convenient.

[0033] In the above embodiment, by providing the filter device 10 with a housing 101 and a filter body 102 disposed within the housing 101, when the filter device 10 needs to be replaced, the filter body 102 can be removed from or inserted into the housing 101, making the assembly and disassembly of the filter device 10 more convenient and facilitating regular replacement of the filter device 10. Furthermore, the ends of the housing 101 and the ends of the filter body 102 are sealed to form an accommodating space 103. Water in the first water tank 20 is filtered by the filter body 102, seeps into the accommodating space 103, and is then discharged through the water outlet 104, thereby extending the service life of the internal components of the filtered water.

[0034] In some implementations, such as Figure 2 As shown, the two ends of the filter body 102 and the two ends of the housing 101 are sealed, that is, a sealing ring 105 is provided between the two ends of the filter body 102 and the two ends of the housing 101, and the sealing ring 105 is clamped and fixed by the filter body 102 and the housing 101. Specifically, grooves can be opened around the two ends of the filter body 102, and the sealing ring 105 can be sleeved inside the grooves. When assembling the filter device 10, the sealing ring 105 can be sleeved into the grooves at the two ends of the filter body 102, and then the filter body 102 is inserted into the housing 101. After the filter body 102 is inserted into the housing 101, the sealing ring 105 is clamped by the filter body 102 and the housing 101, causing the sealing ring 105 to deform, effectively improving the sealing between the two ends of the filter body 102 and the two ends of the housing 101, and facilitating the flow of water in the first water tank 20 into the accommodating space 103.

[0035] In some embodiments, the filter device 10 further includes a filter cover 106, which is snap-fitted to the end of the housing 101 that is away from the filter body 102 and connected to the first water tank 20. The filter cover 106 can be threadedly connected to the housing 101 or snap-fitted into the housing 101, which is not specifically limited in this application. In other embodiments, a groove can be provided at the portion where the filter cover 106 connects to the housing 101, and a sealing ring can be provided within the groove. After the filter cover 106 is installed, the sealing ring can be clamped and fixed by the housing 101 and the filter cover 106, causing the sealing ring to deform, thereby improving the sealing performance of the filter device 10.

[0036] In a specific application scenario, when assembling the filter device 10, the sealing ring 105 is sleeved into the grooves at both ends of the filter body 102, and then the filter body 102 is inserted into the housing 101. The sealing ring 105 is clamped and squeezed by the housing 101 and the filter body 102, thereby improving the sealing between the ends of the filter body 102 and the ends of the housing 101. The filter device 10 is then placed in the first water tank 20, and the filter cover 106 is snapped into the housing 101. When disassembling the filter device 10, the filter cover 106 is removed to expose the filter body 102, and the filter body 102 is then removed from the housing 101.

[0037] In the above manner, the present application provides a filter device 10 within the first water tank 20, wherein the filter device 10 is provided as a housing 101 and a filter body 102 provided within the housing 101. When the filter device 10 needs to be replaced, the filter body 102 can be removed from or inserted into the housing 101, making the assembly and disassembly of the filter device 10 more convenient and facilitating regular replacement of the filter device 10. By providing sealing rings 105 at both ends of the filter body 102 and at both ends of the housing 101, a seal can be provided between the filter body 102 and the housing 101, effectively improving the sealing performance between the two ends of the filter body 102 and the two ends of the housing 101, and facilitating the flow of water within the first water tank 20 into the accommodating space 103. By providing a filter cover 106 at the end of the shell 101 away from the filter body 102 and connected to the first water tank 20, when disassembling the filter device 10, the filter cover 106 can be removed to expose the filter body 102, and then the filter body 102 can be taken out of the shell 101, thereby improving the convenience of disassembly and assembly of the filter device 10.

[0038] See also Figure 3The present application further provides a water system disposed within a toilet body 90. The water system includes a filter device 10 and a first water pump 30. The first water pump 30 is disposed within the toilet body 90 and is connected to a water outlet 104 via a pipeline. The other end of the first water pump 30 is connected to a cleaning assembly 40. The filter device 10 is any of the filter devices 10 described above. The filter device 10 and the first water pump 30 are disposed within the toilet body 90.

[0039] In some embodiments, the filter device 10 and the first water pump 30 are disposed within the toilet body 90, wherein the first water pump 30 is connected to the filter device 10, and the other end of the first water pump 30 is connected to the cleaning assembly 40. That is, when the toilet is in use, the filter device 10 filters the water, and the first water pump 30 transfers the filtered water to the cleaning assembly 40, and then the water is discharged through the cleaning assembly 40.

[0040] In a specific application scenario, the water system and filter device 10 are used in a smart toilet. After the user uses the smart toilet, the first water pump 30 pumps the filtered water from the filter device 10 and delivers it to the cleaning assembly 40. The cleaning assembly 40 then discharges the water to clean the user. The filter device 10 filters the water and pumps it out through the first water pump 30. On the one hand, the filtered water contains less dirt, thereby reducing the dirt deposited in the first water pump 30 and the cleaning assembly 40, which is beneficial for extending the service life of the first water pump 30 and the cleaning assembly 40. On the other hand, when the user uses the cleaning assembly 40 for cleaning, it can effectively ensure the cleanliness of the water flow, improving the user experience.

[0041] In some embodiments, as Figure 5 As shown, the water system includes a first water tank 20 and a second water tank 50. A filter device 10 is disposed within the first water tank 20, which is then disposed within the second water tank 50. The second water tank 50 is then disposed within the toilet bowl 90. When the toilet is in use, water flowing within the first water tank 20 is filtered by the filter device 10 and then pumped to the cleaning assembly 40 via the first water pump 30 for cleaning. This ensures the service life of the cleaning assembly 40 and the first water pump 30 and improves the user experience. Water flowing within the second water tank 50 is used to flush the toilet bowl 90 after use. A second water pump 501 is connected to the bottom of the first water tank 20. After use, the second water pump 501 pumps water from the second water tank 50 to flush the toilet. The second water pump 501 can be a centrifugal pump, but this is not specifically limited in this application.

[0042] In this embodiment, if Figure 4 and Figure 6As shown, an overflow port 201 is provided on the side wall of the first water tank 20, and the overflow port 201 is connected to the second water tank 50. That is, when filling the first water tank 20 and the second water tank 50, water can be first injected into the first water tank 20. After the water level in the first water tank 20 rises to the overflow level of the overflow port 201, the water injected into the first water tank 20 flows into the interior of the second water tank 50 through the overflow port 201, thereby completing the filling of the second water tank 50. In other embodiments, multiple overflow ports 201 can be provided on the first water tank 20, and the overflow ports 201 can have a certain height difference to reduce the risk of excessive water flow causing the water level in the first water tank 20 to rise too quickly, resulting in a single overflow port 201 being unable to completely discharge the water in the first water tank 20 into the second water tank 50. The specific setting can be based on user or process requirements and is not specifically limited in this application.

[0043] In some embodiments, the cleaning component 40 further includes: a heating element 401, a distribution valve 402 and a flushing element 403, wherein the heating element 401, the distribution valve 402 and the flushing element 403 are connected in sequence through pipelines, that is, after the water flow in the first water tank 20 is filtered by the filter device 10, the filtered water flow will be stored in the accommodating space 103 between the shell 101 and the filter body 102. When the cleaning component 40 is used, the shell 101 is provided with a water outlet 104 connected to the accommodating space 103, and the first water tank 20 is connected to the water outlet 104 through a pipeline. The first water tank 20 extracts the water flow in the accommodating space 103 and transports the extracted water flow to the heating element 401, and the heating element 401 processes the water flow. Heating, thereby heating the water flow to a preset temperature. After the water flow is heated to the preset temperature, the water flow is delivered to the distribution valve 402, and the water flow is divided into multiple paths by the distribution valve 402 and delivered to the flushing part 403, so that the flushing part 403 is tilted towards the user, wherein the multiple paths may include, one path is used to clean the user, and another path is used to clean the flushing part 403, so as to clean the flushing part 403 and reduce the contamination of the water flow due to long-term uncleaning of the flushing part 403, thereby reducing the user's experience. The specific path can be set according to the process and customer requirements, and the heating part 401 can heat the water flow to the preset temperature and can be set according to the user's usage habits. This application does not make specific limitations here.

[0044] In some embodiments, as Figure 5As shown, the water system also includes a water inlet 601, which is connected to the first water tank 20. A solenoid valve 602 is provided between the water inlet 601 and the first water tank 20. The water inlet 601 can be connected to tap water, which is delivered to the first water tank 20 through the water inlet 601. After the water level in the first water tank 20 reaches the overflow height of the overflow port 201, the water flows into the second water tank 50, thereby filling the second water tank 50. The water in the first water tank 20 is unfiltered water, that is, after the first water tank 20 is filled with water, the second water tank 50 is filled with water. One end of the water inlet 601 is connected to the first water tank 20, and a solenoid valve 602 is provided between the water inlet 601 and the first water tank 20. The solenoid valve 602 can control whether the water inlet 601 fills the first water tank 20 and the second water tank 50. After the first water tank 20 and the second water tank 50 are filled with water, the solenoid valve 602 can be turned off to stop filling the first water tank 20 and the second water tank 50 with water.

[0045] In a specific application scenario, opening the solenoid valve 602 allows the water inlet 601 to fill the first water tank 20 and the second water tank 50. The water in the first water tank 20 is filtered by the filter device 10. After the user finishes using the toilet, the first water pump 30 pumps the filtered water from the first water tank 20 out of the accommodating space 103 and delivers it to the cleaning assembly 40, which then cleans the user. Furthermore, the second water pump 501 can pump water from the second water tank 50 to clean the toilet.

[0046] In some embodiments, the first water tank 20 is provided with a tank cover 70, which is snapped onto the first water tank 20. The tank cover 70 is provided with an opening 701 that is compatible with the filter body 102, and the filter cover 106 is snapped into the opening 701. That is, the tank cover 70 is provided at the upper end of the first water tank 20 to seal the first water tank 20, thereby ensuring that the water in the first water tank 20 flows out from the upper end of the first water tank 20. In addition, to facilitate the disassembly and assembly of the filter device 10, an opening 701 is provided on the cover plate. The opening 701 is compatible with the size of the filter cover 106, so that the filter cover 106 can be snapped into the opening 701. When disassembling the filter device 10, the filter cover 106 can be removed from the opening 701.

[0047] In this embodiment, a first sensor 702 and a second sensor 703 are provided on the tank cover 70. The first sensor 702 is located in the first water tank 20, and the second sensor 703 is located in the second water tank 50. That is, one end of the first sensor 702 for detecting the water level is located in the first water tank 20, and one end of the second sensor 703 for detecting the water level is located in the second water tank 50. The first sensor 702 and the second sensor 703 are used to respectively detect whether the first water tank 20 and the second water tank 50 are short of water or full of water. When the first water tank 20 is short of water, the solenoid valve 602 can be controlled to open, so that the water inlet 601 starts to fill the first water tank 20 with water. When the water level in the first water tank 20 reaches the water level detected by the first sensor 702, the solenoid valve 602 is controlled to close, so that the water inlet 601 stops filling the first water tank 20 with water. When there is a lack of water in the second water tank 50, the second sensor 703 detects the lack of water in the second water tank 50, and controls the solenoid valve 602 to start filling water into the first water tank 20. The water level in the first water tank 20 reaches the overflow water level of the overflow port 201, and the water flow in the first water tank 20 is injected into the second water tank 50 through the overflow port 201. When the water level in the second water tank 50 reaches the water level detected by the second sensor 703, the solenoid valve 602 is controlled to stop filling water into the first water tank 20, thereby stopping filling water into the first water tank 20 and the second water tank 50.

[0048] Among them, the water level detected by the first sensor 702 may be the same as the overflow water level of the overflow port 201. Since the water flow in the second water tank 50 is injected through the overflow port 201 of the first water tank 20, that is, when there is a shortage of water in the first water tank 20 and the second water tank 50, the solenoid valve 602 opens to start injecting water into the first water tank 20. The on and off of the solenoid valve 602 can be based on the water level detected by the second sensor 703 to inject water or stop injecting water into the first water tank 20. The solenoid valve 602 can also stop injecting water into the first water tank 20 after both the first sensor 702 and the second sensor 703 detect the water level. This application does not make specific restrictions here.

[0049] In a specific application scenario, the filter device 10 and the water system are arranged in the toilet body 90. The water flow in the first water tank 20 is filtered through the filter body 102 and then penetrates into the accommodating space 103 between the outer shell 101 and the filter body 102. After the user uses the toilet, the first water pump 30 extracts the filtered water flow in the accommodating space 103 through the water outlet 104 and delivers it to the heating element 401. The heating element 401 heats the filtered water flow to a preset temperature and delivers it to the distribution valve 402. The distribution valve 402 divides the water flow into multiple paths and delivers it to the flushing element 403. The flushing element 403 cleans the user. When the toilet needs to be cleaned, the second water pump 501 pumps out the water in the second water tank 50 to clean the toilet. At this time, the first water tank 20 and the second water tank 50 are in a water-shortage state. The first sensor 702 and the second sensor 703 respectively detect that the water levels in the first water tank 20 and the second water tank 50 have not reached the preset water level, and control the solenoid valve 602 to open, so that the water inlet part 601 starts to fill water into the first water tank 20. When the water level in the first water tank 20 reaches the overflow water level of the overflow port 201, the unfiltered water in the first water tank 20 is injected into the second water tank 50. After the water levels in the first water tank 20 and the second water tank 50 reach the water levels detected by the first sensor 702 and the second sensor 703, the solenoid valve 602 is controlled to close, so that the water inlet part 601 stops filling water into the first water tank 20.

[0050] Through the above-mentioned method, the present application sets a filter device 10 on the water system. When the water system uses water, the water flow is filtered water flow, which can reduce the impact of dirt in the water flow on the water system and help to improve the service life of the water system. By setting the first water tank 20 inside the second water tank 50, the first water tank 20 is connected to the cleaning component 40, and the second water tank 50 is connected to the second water pump 501, the water flow can be divided into two paths. By setting an overflow port 201 on the first water tank 20, the water flow from the first water tank 20 can be transported to the interior of the second water tank 50. By setting a first sensor 702 and a second sensor 703 on the tank cover 70, which are located in the first water tank 20 and the second water tank 50 respectively, the first sensor 702 detects whether there is a lack of water in the first water tank 20, and the second sensor 703 detects whether there is a lack of water in the second water tank 50. By setting the tilting component as a heating element 401, a distributing valve 402 and a flushing element 403, the water flow can be heated by the heating element 401, thereby improving the customer's usage experience, and the water flow can be divided into two paths by the distributing valve 402, which can clean the user and the flushing element 403.
